Zapalenie narządów miednicy mniejszej
Epidemiologia

Zapalenie narządów miednicy mniejszej (PID) jest ostrym, polimikrobinowym zakażeniem górnego odcinka żeńskiego układu rozrodczego, obejmującym macicę, jajowody i jajniki. W USA rocznie diagnozuje się ponad 1 milion przypadków PID, co generuje około 2,5 miliona wizyt lekarskich i 125-150 tysięcy hospitalizacji. Częstość występowania PID w populacji kobiet w wieku reprodukcyjnym wynosi około 4-5%, z najwyższą zapadalnością u kobiet w wieku 15-25 lat. Główne czynniki ryzyka to młody wiek, wczesne rozpoczęcie współżycia, wielość partnerów seksualnych, stosowanie wkładki wewnątrzmacicznej oraz wcześniejsze zakażenia przenoszone drogą płciową. Etiologia PID jest najczęściej związana z Chlamydia trachomatis (do 60% przypadków) i Neisseria gonorrhoeae, a także coraz częściej z Mycoplasma genitalium. Diagnostyka opiera się głównie na obrazie klinicznym, gdyż brak jest jednoznacznego testu diagnostycznego. Wskaźnik standaryzowany częstości występowania PID wynosi 53,19 na 100 000 populacji, z tendencją spadkową od 1990 roku, co przypisuje się skutecznym programom przesiewowym i leczeniu STI.

Epidemiologia zapalenia narządów miednicy mniejszej

Zapalenie narządów miednicy mniejszej (PID, ang. Pelvic Inflammatory Disease) jest ostrym zakażeniem górnego odcinka układu rozrodczego kobiet, obejmującym macicę, jajowody, jajniki oraz sąsiadujące struktury miednicy. Choroba ta stanowi poważny problem zdrowia publicznego na całym świecie.12 Dokładna ocena częstości występowania PID jest utrudniona ze względu na zróżnicowane objawy, które mogą się znacząco różnić w poszczególnych przypadkach, a także znaczną liczbę przypadków bezobjawowych lub o minimalnych objawach.34

Częstotliwość występowania na świecie

Szacuje się, że rocznie w Stanach Zjednoczonych występuje ponad 750 000 do 1,2 miliona przypadków ostrego PID.56 Według danych Centers for Disease Control and Prevention (CDC), każdego roku diagnozuje się ponad 1 milion przypadków PID, co prowadzi do około 2,5 miliona wizyt w gabinetach lekarskich i 125 000-150 000 hospitalizacji rocznie.7 W 2013 roku zdiagnozowano około 88 000 kobiet w wieku 15-44 lat.8

W badaniu National Health and Nutrition Examination Survey (NHANES) z lat 2013-2014, częstość występowania PID w wywiadzie wśród kobiet w wieku reprodukcyjnym w USA wynosiła 4,4%, co przekłada się na około 2,5 miliona kobiet w wieku 18-44 lat, które otrzymały diagnozę PID w swoim życiu.910 Ogólnie szacuje się, że PID dotyka około 4-5% kobiet w wieku reprodukcyjnym w Stanach Zjednoczonych.1112

W Kanadzie szacuje się, że rocznie diagnozuje się około 100 000 przypadków objawowego PID, a 10-15% kobiet w wieku reprodukcyjnym miało przynajmniej jeden epizod PID.13 W Anglii według badania z lat 2014-2023, wskaźniki diagnozowania PID u kobiet w wieku 15-44 lat wynosiły odpowiednio: 238 na 100 000 populacji w warunkach szpitalnych (26 454 diagnozy), 67 na 100 000 populacji w placówkach SHS (7 499 diagnoz) i 107 na 100 000 osobolat w placówkach GP (3 500 diagnoz).14

W krajach o wysokim dochodzie roczny wskaźnik PID zgłaszano na poziomie nawet 10-20 na 1000 kobiet w wieku reprodukcyjnym.15 Według danych z 2019 roku, standaryzowany według wieku wskaźnik (ASR) częstości występowania PID wynosił 53,19 na 100 000 populacji, ze spadkową tendencją od 1990 roku.16

Trendy epidemiologiczne

W ostatnich dekadach zauważono ogólny trend spadkowy w częstości występowania PID w Stanach Zjednoczonych i Europie Zachodniej, prawdopodobnie dzięki zwiększonym badaniom przesiewowym i leczeniu chlamydii i rzeżączki.1718 Dane z narodowych roszczeń ubezpieczeniowych, wizyt w gabinetach lekarskich i oddziałach ratunkowych wskazują na ogólny trend spadkowy zachorowalności na PID w Stanach Zjednoczonych od 2000 roku.19

Pomimo tego ogólnego spadku, niektóre badania wskazują na wzrost częstości występowania rzeżączki i chlamydii, co może wpływać na przyszłe trendy PID.20 W Wielkiej Brytanii badanie z 2021 roku wykazało, że między 2009 a 2019 rokiem wskaźniki PID związanego z chlamydią spadły o 58%, jednak PID związane z rzeżączką wzrosło o 34%.21

Czynniki demograficzne

PID najczęściej występuje u młodych, aktywnych seksualnie kobiet. Największą zapadalność obserwuje się u kobiet w wieku 15-25 lat, przy czym 75% przypadków dotyczy kobiet poniżej 25 roku życia.2223 Szczyt zachorowań przypada na wiek 15-29 lat, choć choroba może wystąpić u kobiet do 40 roku życia.24 Wskaźniki PID są najwyższe wśród kobiet w wieku 20-24 lat.25

Dane demograficzne wskazują, że PID jest przede wszystkim chorobą osób młodych.26 Wskaźniki są najwyższe wśród nastolatek i kobiet rodzących po raz pierwszy.27 U nastolatków w Lund w Szwecji w latach 70. roczna zapadalność wynosiła 1,5%.28

Rasa również wydaje się być determinantem, choć nie jest jasne, czy z przyczyn biologicznych czy socjologicznych.29 W Stanach Zjednoczonych kobiety rasy czarnej mają prawie dwukrotnie wyższy wskaźnik PID niż kobiety rasy białej.30 Bez wcześniejszego wywiadu STI, częstość występowania PID w ciągu życia jest wyższa u kobiet rasy czarnej w porównaniu do kobiet rasy białej (6% vs 2,7%).31 Wśród pacjentek z wcześniejszym STI, częstość występowania w ciągu życia była podobna niezależnie od rasy (10% vs 10,3%).32

Czynniki ryzyka

Badania epidemiologiczne wykazały liczne czynniki związane z PID, z których wiele pokrywa się z czynnikami znanymi jako związane z nabyciem zakażeń powodujących PID.33 Do głównych czynników ryzyka należą:

  • Wiek poniżej 25 lat3435
  • Wczesny wiek rozpoczęcia współżycia seksualnego3637
  • Duża liczba partnerów seksualnych3839
  • Ryzykowne zachowania seksualne40
  • Partner z zakażeniem przenoszonym drogą płciową41
  • Historia wcześniejszego PID lub zakażenia przenoszonego drogą płciową42
  • Stan cywilny – kobiety niezamężne są bardziej narażone na PID niż kobiety zamężne43
  • Stosowanie wkładki wewnątrzmacicznej (IUD) – niewielki wzrost ryzyka w okresie tuż po założeniu4445
  • Irygacje pochwy (douching)4647
  • Palenie tytoniu48

Etiologia zapalenia narządów miednicy mniejszej

Zapalenie narządów miednicy mniejszej jest zwykle wynikiem wstępującego zakażenia polimikrobialnego z dolnego odcinka układu rozrodczego.4950 Większość przypadków PID (ponad 85%) jest spowodowana przez patogeny przenoszone drogą płciową lub patogeny związane z bakteryjną waginozą.51

Główne czynniki zakaźne

Dwa najważniejsze organizmy przenoszone drogą płciową związane z ostrym PID to Chlamydia trachomatis i Neisseria gonorrhoeae, które powinny być głównymi celami leczenia.52 C. trachomatis jest najważniejszym identyfikowalnym patogenem i odpowiada za do 60% PID w krajach północnoeuropejskich.53 Około 10-15% osób zakażonych C. trachomatis lub N. gonorrhoeae rozwija PID.5455

Coraz częściej uznawana jest również rola Mycoplasma genitalium w patogenezie PID, chociaż ograniczone możliwości testowania i dane badawcze utrudniają proaktywne działania w kierunku jej identyfikacji i leczenia.56 PID spowodowane przez M. genitalium jest zwykle bezobjawowe lub łagodne, z mniej nasilonymi bólami miednicy, mniejszą śluzowo-ropną wydzieliną szyjki macicy i mniejszą liczbą markerów zapalenia.57

W większości przypadków konkretna etiologia mikrobiologiczna PID jest nieznana i nie identyfikuje się określonego organizmu. C. trachomatis, N. gonorrhoeae i M. genitalium odpowiadają za szacunkowe 30-40% przypadków.58

Inne patogeny

Mniej niż 15% przypadków ostrego PID jest związanych z patogenami jelitowymi (np. Escherichia coli, Bacteroides fragilis, paciorkowce grupy B i Campylobacter spp.) lub patogenami układu oddechowego (np. Haemophilus influenzae, Streptococcus pneumoniae, paciorkowce grupy A i Staphylococcus aureus), które skolonizowały dolny odcinek układu rozrodczego.59

Inne mikroorganizmy związane z PID mogą obejmować mykoplazmy, bakterie beztlenowe i względnie beztlenowe (tlenowe), paciorkowce, mykoplazmy genitalne i Gardnerella vaginalis, która jest związana z bakteryjną waginozą.6061

Systemy nadzoru i raportowanie

PID nie jest chorobą podlegającą obowiązkowemu zgłaszaniu w Stanach Zjednoczonych i wielu innych krajach, co utrudnia dokładne określenie jego rozpowszechnienia.6263 Pomimo braku konkretnych wymogów raportowania dla PID, wszystkie stany mają przepisy i regulacje, które wymagają od klinicystów, laboratoriów lub obu, zgłaszania kobiet z PID, które mają pozytywny wynik testu na rzeżączkę lub chlamydię, do organów zdrowia publicznego.64

Oszacowanie częstości występowania i zapadalności na PID jest również utrudnione ze względu na brak pojedynczego standardowego testu diagnostycznego dla PID.65 Szacunki PID często opierają się na danych o przyjęciach do szpitala, które obejmują tylko skomplikowane przypadki.66

Badanie Global Burden of Disease (GBD) corocznie ocenia różne wskaźniki chorób od 1990 roku, co daje fantastyczną szansę na porównawczą ocenę obciążenia chorobami i trendów w 204 krajach i terytoriach na całym świecie.67 Takie badania pozwalają lepiej zrozumieć globalne obciążenie PID i jego zmiany w czasie.

Metody diagnozowania i raportowania

Diagnoza PID jest często trudna ze względu na subtelne i łagodne objawy.68 Ponieważ nie ma precyzyjnych testów na PID, diagnoza zwykle opiera się na wynikach klinicznych.69 PID reprezentuje spektrum zakażenia i nie ma jednego złotego standardu diagnostycznego. Diagnoza kliniczna pozostaje najważniejszym praktycznym podejściem.70

Kilka eksperckich wytycznych omawia kliniczne podejście do diagnozy PID. Należą do nich wytyczne amerykańskich Centrów Kontroli i Zapobiegania Chorobom dotyczące zarządzania STI, europejskie wytyczne International Union against STI dotyczące zarządzania PID oraz wytyczne British Association for Sexual Health and HIV dotyczące zarządzania PID.71

Ze względu na trudności w diagnozie i potencjalne zagrożenie dla zdrowia reprodukcyjnego kobiet, lekarze powinni zachować wysoki wskaźnik podejrzenia PID.72 Wczesna diagnoza i leczenie uważane są za kluczowe elementy w zapobieganiu długoterminowym następstwom, takim jak niepłodność i ciąża pozamaciczna.73

Konsekwencje zdrowotne i społeczne

Zapalenie narządów miednicy mniejszej powoduje znaczące problemy medyczne, społeczne i ekonomiczne na całym świecie.74 Opóźnione leczenie PID ma silny związek z pogorszonymi wynikami i długoterminowymi powikłaniami. Jednakże nawet przy szybkim leczeniu mogą wystąpić długoterminowe powikłania.75

Główne powikłania zdrowotne

Nieleczone PID może prowadzić do tworzenia się tkanki bliznowatej i kieszonek zakażonego płynu (ropni) w układzie rozrodczym, co może spowodować trwałe uszkodzenia.76 Długoterminowe następstwa, szczególnie niepłodność jajowodowa, ciąża pozamaciczna i przewlekły ból miednicy są powszechne i niezwykle kosztowne.77

Jedno badanie oszacowało, że w przypadku kobiet z PID w wieku 20-24 lat, u 18% ostatecznie rozwinie się przewlekły ból, u 8,5% wystąpi ciąża pozamaciczna, a 16,8% będzie miało problemy z niepłodnością.78 Szacuje się, że PID odpowiada za 94% zachorowalności u kobiet związanej z zakażeniami przenoszonymi drogą płciową, w tym HIV w krajach o wysokim dochodzie.79

PID jest główną przyczyną niepłodności jajowodowej (około 30% przypadków), 50% ciąż pozamacicznych i jedną z najczęstszych przyczyn potencjalnie możliwego do uniknięcia przewlekłego bólu miednicy.80 Każdego roku w USA ponad 100 000 kobiet staje się niepłodnych w wyniku PID.81

Ryzyko długoterminowych następstw zwiększa się wraz z liczbą epizodów PID. Kobiety z powtarzającymi się epizodami PID są bardziej narażone na niepłodność, ciążę pozamaciczną lub przewlekły ból miednicy.82 Niedrożność jajowodów stwierdzono u 12,8% pacjentek po jednym zakażeniu, u 35,5% pacjentek po dwóch zakażeniach i u 75% pacjentek po trzech lub więcej zakażeniach.83

Wpływ społeczny i ekonomiczny

PID powoduje znaczące obciążenie dla systemu opieki zdrowotnej. Każdego roku w USA jest ponad 150 000 przyjęć związanych z PID.84 PID jest najczęstszą ginekologiczną przyczyną przyjęć do szpitala w Stanach Zjednoczonych, stanowiąc 18 na 10 000 zarejestrowanych wypisów ze szpitali.85

Koszty bezpośrednie i pośrednie PID i jego następstw są znaczne, szacuje się, że przekraczają 2000 dolarów kosztów na osobę w ciągu życia.86 Wskaźniki zachorowalności w częściach Afryki, Azji i Ameryki Południowej, gdzie opieka zdrowotna nie jest łatwo dostępna, są bardzo wysokie.87

Istnieją również doniesienia, że PID może być związane z wyższym ryzykiem udaru i raka jajnika.88 Ponadto, kobiety z PID są bardziej narażone na zakażenie HIV, jeśli zostaną na nie narażone.89

Strategie zapobiegania i kontroli

Zapalenie narządów miednicy mniejszej jest w dużej mierze możliwe do uniknięcia poprzez wczesne rozpoznanie i leczenie chorób przenoszonych drogą płciową (STDs).90 Wysiłki w zakresie zdrowia publicznego wdrożone w Skandynawii w celu zmniejszenia częstości występowania STI okazały się bardzo skuteczne w zmniejszeniu zapadalności na PID.91

Badania przesiewowe i wczesne leczenie

CDC zaleca coroczne badania w kierunku chlamydii u wszystkich aktywnych seksualnie kobiet w wieku 25 lat lub młodszych, starszych kobiet z czynnikami ryzyka zakażenia chlamydią (które mają nowego partnera seksualnego lub wielu partnerów seksualnych) oraz wszystkich kobiet w ciąży.9293

Badania przesiewowe i wczesne leczenie STI, szczególnie chlamydii, wykazały zmniejszenie zapadalności na PID.94 Randomizowane badania kontrolowane sugerują, że zapobieganie zakażeniu chlamydią zmniejsza zapadalność na PID.95

Szybkie i odpowiednie leczenie może zapobiec poważnym uszkodzeniom narządów rozrodczych.96 Im wcześniej PID jest leczone, tym mniejsze uszkodzenia wyrządzi układowi rozrodczemu.97 Im dłużej kobieta opóźnia leczenie PID, tym bardziej prawdopodobne jest, że stanie się niepłodna lub będzie miała w przyszłości ciążę pozamaciczną z powodu uszkodzenia jajowodów.98

Praktyki bezpieczniejszego seksu

Kobiety mogą chronić się przed PID, podejmując działania zapobiegające STD lub uzyskując wczesne leczenie, jeśli zachorują na STD.99100 Inne metody zapobiegania PID i chorobom przenoszonym drogą płciową obejmują zmniejszenie liczby partnerów seksualnych, unikanie niebezpiecznych praktyk seksualnych i używanie prezerwatyw ze środkiem plemnikobójczym.101

Stosowanie barier mechanicznych ze środkiem plemnikobójczym również zmniejsza ryzyko nabywania chorób przenoszonych drogą płciową.102 Metody barierowe antykoncepcji wydają się zmniejszać ryzyko PID, podobnie jak antykoncepcja doustna.103

Brak kontaktów seksualnych (abstynencja) jest jedynym pewnym sposobem uniknięcia zakażenia.104 Jeśli wybiera się aktywność seksualną, używanie lateksowych lub poliuretanowych prezerwatyw za każdym razem podczas seksu oralnego, analnego lub waginalnego obniży szanse na ponowne zachorowanie na PID.105

Edukacja i świadomość

Każdy kraj powinien ustanowić kompleksową edukację seksualną, która obejmuje edukację na temat zapobiegania STI.106 Rosnąca świadomość i edukacja na temat PID i jego związku z STI są kluczowymi elementami strategii zapobiegania.107

Ważne jest, aby rozmawiać z partnerem tak szybko, jak to możliwe, aby mógł on/ona otrzymać leczenie.108 Wszyscy ostatni partnerzy seksualni kobiet z PID powinni zostać poddani ocenie i empirycznemu leczeniu chlamydii i rzeżączki, niezależnie od patogenów zidentyfikowanych u kobiety z PID.109

Nowe wyzwania i kierunki badań

Pomimo postępów w diagnozowaniu i leczeniu PID, wciąż istnieją istotne wyzwania i obszary wymagające dalszych badań. Jednym z głównych wyzwań jest oporność na leki w leczeniu zakażeń rzeżączkowych.110 Na przykład częstość występowania oporności na fluorochinolony w N. gonorrhoeae sięga prawie 100% w niektórych regionach, a te środki nie są już zalecane do leczenia zakażeń N. gonorrhoeae.111

Odstępstwa od wytycznych leczenia PID są ogólnym problemem ze względu na ryzyko następstw, takich jak niepłodność, przewlekły ból miednicy, ciąże pozamaciczne i ryzyko sprzyjania oporności na antybiotyki.112 Pomimo istniejących zaleceń dotyczących postępowania w przypadku PID, wiele badań wskazuje na nieprzestrzeganie tych wytycznych przez niektórych świadczeniodawców.113

W świetle narastającej oporności na antybiotyki, trwają wysiłki mające na celu identyfikację najbardziej skutecznych klinicznie i opłacalnych podejść do leczenia PID.114 Standaryzacja schematów leczenia PID odzwierciedla obecną praktykę w społeczeństwach rozwiniętych. W przeciwieństwie do tego, postępowanie w przypadku PID jest mniej znormalizowane w krajach o niskim i średnim dochodzie, a istnieją duże różnice w stosowaniu antybiotyków ze względu na ograniczenia narzucone przez koszty i słabo rozwinięte systemy opieki zdrowotnej.115

Testowanie w miejscu opieki (POC) w kierunku STI podczas zakażenia bezobjawowego pozwoli na wczesną interwencję i pierwotną profilaktykę przyszłych następstw reprodukcyjnych.116 Wsparcie w przestrzeganiu zaleceń może być konieczne, aby pomóc pacjentom w leczeniu.117

Potrzebne są dalsze badania, aby ocenić stopień nakładania się rutynowych źródeł danych dla PID i historii PID u kobiet zdiagnozowanych z PID.118 Metody diagnostyczne i wiedza na temat etiologii chorób muszą zostać ulepszone, jeśli mają być podjęte dalsze badania epidemiologiczne i inicjatywy nadzoru.119

  • #1 Global burden of pelvic inflammatory disease and ectopic pregnancy from 1990 to 2019 | BMC Public Health | Full Text
    https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-023-16663-y
    Pelvic inflammatory disease (PID) is a widespread female public problem worldwide. And it could lead to infertility, preterm labor, chronic pelvic pain, and ectopic pregnancy (EP) among reproductive-aged women. This study aimed to assess the global burden and trends as well as the changing correlation between PID and EP in reproductive-aged women from 1990 to 2019. […] In 2019, the ASR of PID prevalence was 53.19 per 100,000 population with a decreasing trend from 1990 (EAPC:0.50), while the ASR of EP incidence was 342.44 per 100,000 population with a decreasing trend from 1990 (EAPC:1.15). […] General negative correlations between the socio-demographic index and the ASR of PID prevalence and the ASR of EP incidence were observed at the national levels. […] PID and EP continue to be public health burdens with a strong correlation despite slightly decreasing trends detected in ASRs globally.
  • #2 Pelvic inflammatory disease: Clinical manifestations and diagnosis – UpToDate
    https://www.uptodate.com/contents/pelvic-inflammatory-disease-clinical-manifestations-and-diagnosis
    Pelvic inflammatory disease (PID) refers to acute and subclinical infection of the upper genital tract in females, involving any or all of the uterus, fallopian tubes, and ovaries; this is often accompanied by involvement of the neighboring pelvic organs. It results in endometritis, salpingitis, oophoritis, peritonitis, perihepatitis, and/or tubo-ovarian abscess. […] The majority of PID cases (over 85 percent) are caused by sexually transmitted pathogens or bacterial vaginosis-associated pathogens. Fewer than 15 percent of acute PID cases are associated with enteric (eg, Escherichia coli, Bacteroides fragilis, Group B streptococci, and Campylobacter spp) or respiratory pathogens (eg, Haemophilus influenzae, Streptococcus pneumoniae, Group A streptococci, and Staphylococcus aureus) that have colonized the lower genital tract.
  • #3 Epidemiology of Pelvic Inflammatory Disease | RTI
    https://www.rti.org/publication/epidemiology-pelvic-inflammatory-disease
    The epidemiologic study of pelvic inflammatory disease (PID) is hindered by symptoms that differ substantially from case to case, and by a substantial number of ”silent” cases with few or no symptoms. […] Demographic data indicate that PID is primarily a disease of the young. […] Race also appears to be a determinant, but whether for biologic or sociologic reasons is not known. […] Women who are not married face a greater risk for PID than married women. […] The majority of PID cases are associated with sexually transmitted diseases. […] Consistent with this finding is the pattern of risk factors related to sexual behavior: young age at first intercourse, high frequency of intercourse, and a large number of sexual partners all increase the risk of PID. […] On the other hand, barrier methods of contraception appear to reduce the risk of PID, as does oral contraception.
  • #4 Core Concepts – Pelvic Inflammatory Disease – Self-Study Lessons – National STD Curriculum
    https://www.std.uw.edu/go/comprehensive-study/pelvic-inflammatory-disease/core-concept/all
    Pelvic inflammatory disease (PID) is a clinical syndrome characterized by infection and inflammation of the upper female genital tract. This process results from the ascending spread of microorganisms in the vagina or cervix to the structures of the upper female genital tract, with potential infection and inflammation of the endometrium, fallopian tubes, pelvic peritoneum, and, in some instances, formation of tubo-ovarian abscess. […] It is difficult to accurately estimate the incidence and prevalence of PID in the United States as there is no single diagnostic test for PID, and it is not a reportable disease. In a comprehensive review of two sentinel data sources (National Health and Nutrition Examination Survey [NHANES] and the National Survey of Family Growth [NSFG]), investigators summarized the burden of and trends in PID among reproductive-aged women (18 to 44 years of age) in the United States and estimated a 4% self-reported history of PID and estimated 2 million or more reproductive-aged women in the United States having a diagnosis of PID in their lifetime.
  • #5 Pelvic Inflammatory Disease – StatPearls – NCBI Bookshelf
    https://www.ncbi.nlm.nih.gov/books/NBK499959/
    PID occurs most frequently in women ages 15 to 25 years. In 2001 there were more than 750,000 cases of PID in the United States. Over the past decade, the rates of PID have been decreasing, but it is still commonly seen in both outpatient clinics and emergency department settings. […] Delayed treatment of PID has a strong association with worsened outcomes and long-term complications. However, even with timely treatment, long-term complications can occur. One study estimated that for females with PID between 20 to 24 years of age, 18% would eventually develop chronic pain, 8.5% would develop ectopic pregnancies, and 16.8% would struggle with infertility. […] Each year there are over 150,000 admissions related to PID. The complication rates in parts of Africa, Asia, and South America where health care is not readily accessible are very high. There are also reports that PID may be associated with a higher risk of stroke and ovarian cancer.

    Pelvic inflammatory disease epidemiology and demographics On the Web […] It is estimated that between 750,000 and 1.2 million women are affected by PID each year in the United States. […] Incidence and prevalence are decreasing since 1985 because of widespread chlamydia screening and treatment. […] PID is the most common gynecologic reason for hospital admission in the United States, accounting for 18 per 10,000 recorded hospital discharges. […] Approximately 50,000 women become infertile in the US each year as a consequence of PID. […] PID is a common disease that tends to affect young women between the ages of 15 and 29 years. […] In the United States, African-American or Black-Caribbean ethnicity has been associated with a higher risk of PID.
  • #7 Pelvic Inflammatory Disease: Practice Essentials, Background, Pathophysiology
    https://emedicine.medscape.com/article/256448-overview
    Among 1171 sexually experienced reproductive-aged women in the 2013-2014 National Health and Nutrition Education Survey (NHANES) the prevalence of self-reported lifetime PID was 4.4%. Therefore, approximately 2.5 million women aged 18-44 years nationwide have received a diagnosis of PID in their lifetime (95% CI = 1.8-3.2 million). […] The CDC has estimated that more than 1 million women experience an episode of PID every year. The disease leads to approximately 2.5 million office visits and 125,000-150,000 hospitalizations yearly. […] No specific international data are available for PID incidence worldwide. In 2005, however, the World Health Organization (WHO) estimated that approximately 448 million new cases of curable STIs occur annually in individuals aged 15-49 years. […] The annual rate of PID in high-income countries has been reported to be as high as 10-20 per 1000 women of reproductive age. Public health efforts implemented in Scandinavia to decrease the prevalence of STIs have been quite effective in reducing the incidence of PID.
  • #8 Pelvic inflammatory disease
    https://womenshealth.gov/a-z-topics/pelvic-inflammatory-disease
    Pelvic inflammatory disease (PID) is an infection of a woman’s reproductive organs. In 2013, about 88,000 women ages 15-44 in the United States were diagnosed with PID. PID affects about 5% of women in the United States. The number of women with PID has dropped in recent years. This may be because more women are getting tested regularly for chlamydia and gonorrhea. […] If you think that you may have PID, see a doctor or nurse as soon as possible. […] Without treatment, PID can lead to serious problems like infertility, ectopic pregnancy, and chronic pelvic pain (pain that does not go away). If you think you may have PID, see a doctor or nurse as soon as possible. […] Ectopic pregnancies are more than six times more common in women who have had PID compared with women who have not had PID.

    Pelvic inflammatory disease (PID) is an ascending inflammatory process affecting the female upper genital tract. […] There are limited contemporary data on the prevalence, incidence, or burden of PID worldwide and the true incidence of disease is difficult to accurately estimate given the frequency of mildly symptomatic or asymptomatic disease. Published data suggest an overall decline in the rates and severity of PID in North America and western Europe, likely due to increased screening and treatment of gonorrhea and chlamydia. Nevertheless, PID remains a frequent and burdensome condition affecting women of reproductive age. Using data from two nationally representative probability surveys collecting self-reported PID history during 2006-2016, it was estimated that more than 2 million reproductive-aged US women have received a PID diagnosis in their lifetime.

    Pelvic inflammatory disease (PID) is an infection of a woman’s reproductive organs. In 2013, about 88,000 women ages 15-44 in the United States were diagnosed with PID. PID affects about 5% of women in the United States. The number of women with PID has dropped in recent years. This may be because more women are getting tested regularly for chlamydia and gonorrhea. […] If you think that you may have PID, see a doctor or nurse as soon as possible. […] Without treatment, PID can lead to serious problems like infertility, ectopic pregnancy, and chronic pelvic pain (pain that does not go away). If you think you may have PID, see a doctor or nurse as soon as possible. […] Ectopic pregnancies are more than six times more common in women who have had PID compared with women who have not had PID.

    Pelvic inflammatory disease (PID) is caused by a bacterial infection that spreads beyond the cervix to infect the upper female reproductive tract, i.e., the uterus (endometritis), fallopian tubes (salpingitis), and/or ovaries (oophoritis). […] Lifetime prevalence: 4.5% in women of reproductive age (1844 years). […] 1 million women experience an episode of PID/year. […] PID is one of the most common causes of infertility.

    PID is the most common infectious cause of lower abdominal pain in females. Up to two-thirds of cases may not be recognized. […] In Canada, there are approximately 100,000 cases of symptomatic PID diagnosed annually. In addition, it is estimated that 10%-15% of reproductive-aged females have had at least one episode of PID. […] Long-term sequelae of PID include infertility, ectopic pregnancy and chronic pelvic pain. The likelihood of developing these long-term sequelae is related to the number of PID episodes the person has experienced. […] PID can be a complicated polymicrobial infection. Etiologic agents associated with PID may include sexually transmitted infections (STIs) and endogenous anaerobic and facultative (aerobic) bacteria. […] In most cases, the specific microbial etiology of PID is unknown and no specific organism is identified. Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) are the most identified STIs in cases of PID. CT, GC and Mycoplasma genitalium account for an estimated 30%-40% of cases.

    Among 1171 sexually experienced reproductive-aged women in the 2013-2014 National Health and Nutrition Education Survey (NHANES) the prevalence of self-reported lifetime PID was 4.4%. Therefore, approximately 2.5 million women aged 18-44 years nationwide have received a diagnosis of PID in their lifetime (95% CI = 1.8-3.2 million). […] The CDC has estimated that more than 1 million women experience an episode of PID every year. The disease leads to approximately 2.5 million office visits and 125,000-150,000 hospitalizations yearly. […] No specific international data are available for PID incidence worldwide. In 2005, however, the World Health Organization (WHO) estimated that approximately 448 million new cases of curable STIs occur annually in individuals aged 15-49 years. […] The annual rate of PID in high-income countries has been reported to be as high as 10-20 per 1000 women of reproductive age. Public health efforts implemented in Scandinavia to decrease the prevalence of STIs have been quite effective in reducing the incidence of PID.

    Pelvic inflammatory disease (PID) is a widespread female public problem worldwide. And it could lead to infertility, preterm labor, chronic pelvic pain, and ectopic pregnancy (EP) among reproductive-aged women. This study aimed to assess the global burden and trends as well as the changing correlation between PID and EP in reproductive-aged women from 1990 to 2019. […] In 2019, the ASR of PID prevalence was 53.19 per 100,000 population with a decreasing trend from 1990 (EAPC:0.50), while the ASR of EP incidence was 342.44 per 100,000 population with a decreasing trend from 1990 (EAPC:1.15). […] General negative correlations between the socio-demographic index and the ASR of PID prevalence and the ASR of EP incidence were observed at the national levels. […] PID and EP continue to be public health burdens with a strong correlation despite slightly decreasing trends detected in ASRs globally.

    Available data from national insurance claims, visits to office-based physicians, and emergency departments point to an overall trend of decline in the incidence of PID in the United States since the year 2000. […] Epidemiologic studies have revealed numerous factors associated with PID, and many of these factors overlap with those known to be associated with acquisition of infections that cause PID. […] The organisms associated with PID depend on whether the PID is acute (duration of 30 days or less) or chronic (duration of 30 days or more). […] With acute PID, the ascending organisms trigger an inflammatory response that involves the endometrium, fallopian tubes, and/or the pelvic peritoneum. […] The sequelae of PID, including ectopic pregnancy, infertility, or chronic pelvic pain, may occur after a single episode of symptomatic PID. In addition, available data suggest women with subclinical PID can develop long-term sequelae, including infertility.

    Pelvic inflammatory disease (PID) is an ascending inflammatory process affecting the female upper genital tract. […] There are limited contemporary data on the prevalence, incidence, or burden of PID worldwide and the true incidence of disease is difficult to accurately estimate given the frequency of mildly symptomatic or asymptomatic disease. Published data suggest an overall decline in the rates and severity of PID in North America and western Europe, likely due to increased screening and treatment of gonorrhea and chlamydia. Nevertheless, PID remains a frequent and burdensome condition affecting women of reproductive age. Using data from two nationally representative probability surveys collecting self-reported PID history during 2006-2016, it was estimated that more than 2 million reproductive-aged US women have received a PID diagnosis in their lifetime.

Over the past decade, the rates of PID have been decreasing, but it is still commonly seen in both outpatient clinics and emergency department settings. […] Delayed treatment of PID has a strong association with worsened outcomes and long-term complications. However, even with timely treatment, long-term complications can occur. One study estimated that for females with PID between 20 to 24 years of age, 18% would eventually develop chronic pain, 8.5% would develop ectopic pregnancies, and 16.8% would struggle with infertility. […] Each year there are over 150,000 admissions related to PID. The complication rates in parts of Africa, Asia, and South America where health care is not readily accessible are very high. There are also reports that PID may be associated with a higher risk of stroke and ovarian cancer.

    Pelvic inflammatory disease (PID) is the most common serious infection of women. Pelvic inflammatory disease is a cause of about 30% of infertility, 50% of ectopic pregnancies, and it is one of the most common causes of potentially preventable chronic pelvic pain. Pelvic inflammatory disease is not a reportable disease in the United States and precise figures on its prevalence are not available. Based upon a variety of sources, it is estimated that 10% to 15% of reproductive age women have had one episode of PID. An estimated 750,000 new cases occur annually. The rate of PID is highly dependent on age. Among teenagers, an annual 1.5% incidence occurred in Lund, Sweden during the 1970s. In the United States, black women have nearly twice the rate of PID as white women. Between 1982 and 1988, a drop occurred in the cumulative rate of PID in all demographic groups except for white teenagers. There was also an encouraging drop in hospitalization for multiple episodes of PID during this span.

    Pelvic inflammatory disease (PID) is an infection of the female reproductive organs. It most often occurs when sexually transmitted bacteria spread from your vagina to your uterus, fallopian tubes or ovaries. […] Pelvic inflammatory disease (PID) is an infection of one or more of the upper reproductive organs, including the uterus, fallopian tubes and ovaries. Untreated can cause scar tissue and pockets of infected fluid (abscesses) to develop in the reproductive tract, which can cause permanent damage. […] Many types of bacteria can cause PID, but gonorrhea or chlamydia infections are the most common. These bacteria are usually acquired during unprotected sex. […] There is a small increased risk of PID after the insertion of an intrauterine device (IUD). This risk is generally confined to the first three weeks after insertion.

    Pelvic Inflammatory Disease (PID) Information […] PID occurs when STD germs spread from the vagina up into the uterus and other organs. […] Untreated PID can lead to infertility, abnormal pregnancy, and/or chronic pain. […] Sexually active women in their childbearing years are most at risk, and those under age 25 are more likely to develop PID than those older than 25. […] The more sex partners a woman has, the greater her risk of developing PID. […] Women who douche may have a higher risk of developing PID compared with women who do not douche. […] Women who have an intrauterine device (IUD) inserted may have a slightly increased risk of PID near the time of insertion compared with women using other contraceptives or no contraceptive at all.

    PID is primarily a disease of sexually active females. The two most important sexually transmitted organisms associated with acute PID, C. trachomatis and N. gonorrhoeae, should be the main targets for treatment. Even if endocervical testing is not positive for either of these pathogens, they should still be covered, as upper tract infection cannot be ruled out.

    Pelvic inflammatory disease (PID) is the most common serious infection of women. Pelvic inflammatory disease is a cause of about 30% of infertility, 50% of ectopic pregnancies, and it is one of the most common causes of potentially preventable chronic pelvic pain. Pelvic inflammatory disease is not a reportable disease in the United States and precise figures on its prevalence are not available. Based upon a variety of sources, it is estimated that 10% to 15% of reproductive age women have had one episode of PID. An estimated 750,000 new cases occur annually. The rate of PID is highly dependent on age. Among teenagers, an annual 1.5% incidence occurred in Lund, Sweden during the 1970s. In the United States, black women have nearly twice the rate of PID as white women. Between 1982 and 1988, a drop occurred in the cumulative rate of PID in all demographic groups except for white teenagers. There was also an encouraging drop in hospitalization for multiple episodes of PID during this span.

    Pelvic inflammatory disease (PID) inflammation of the upper genital tract may include cervicitis, endometritis, salpingitis, tubo-ovarian abscess and pelvic peritonitis. PID usually occurs from ascending micro-organisms from the vagina and cervix, although a causative organism is not always isolated.

Early diagnosis and treatment reduces the risk of long-term sequelae, including chronic pelvic pain and tubal factor infertility. […] PID is not a notifiable condition and no national surveillance or reporting requirements exist. Estimates of PID incidence are limited and are largely based on hospital admission data, which only include complicated cases. Studies suggest most PID is treated in general practice and ambulatory settings. Recent research indicates hospitalisation for PID has decreased over the last two decades, which may be associated with increased chlamydia screening and treatment in outpatient settings. […] Prompt treatment is necessary to decrease the risk of long-term complications, which include ectopic pregnancy, infertility and chronic pelvic pain. Broad-spectrum antibiotic treatment is necessary to cover sexually transmitted infections and aerobic and anaerobic bacteria.

    PID causes major medical, social, and economic problems worldwide. Long-term sequelae, specifically tubal factor infertility, ectopic pregnancy, and chronic pelvic pain are common and extremely costly. It is estimated that PID accounts for 94% of morbidity in women associated with sexually transmitted infections (STIs), including HIV in high-income countries.

    Pelvic inflammatory disease (PID) is the most common serious infection of women. Pelvic inflammatory disease is a cause of about 30% of infertility, 50% of ectopic pregnancies, and it is one of the most common causes of potentially preventable chronic pelvic pain. Pelvic inflammatory disease is not a reportable disease in the United States and precise figures on its prevalence are not available. Based upon a variety of sources, it is estimated that 10% to 15% of reproductive age women have had one episode of PID. An estimated 750,000 new cases occur annually. The rate of PID is highly dependent on age. Among teenagers, an annual 1.5% incidence occurred in Lund, Sweden during the 1970s. In the United States, black women have nearly twice the rate of PID as white women. Between 1982 and 1988, a drop occurred in the cumulative rate of PID in all demographic groups except for white teenagers. There was also an encouraging drop in hospitalization for multiple episodes of PID during this span.

    Aside from AIDS, the most common and serious complication of sexually transmitted diseases (STDs) among women is pelvic inflammatory disease (PID), an infection of the upper genital tract. Each year in the United States, more than 1 million women experience an episode of acute PID, with the rate of infection highest among teenagers. More than 100,000 women become infertile each year as a result of PID, and a large proportion of the 70,000 ectopic (tubal) pregnancies occurring every year are due to the consequences of PID. […] Recent data indicate that women who douche once or twice a month may be more likely to have PID than those who douche less than once a month. […] About one-fourth of women with suspected PID must be hospitalized. […] Women with recurrent episodes of PID are more likely than women with a single episode to suffer scarring of the tubes that leads to infertility, tubal pregnancy, or chronic pelvic pain. Infertility occurs in approximately 20 percent of women who have had PID. […] As many as one-third of women who have had PID will have the disease at least one more time.

    As many as 15 percent of women with PID may become infertile, and if a woman has multiple episodes of PID, her chances of becoming infertile increase. […] Women with repeated episodes of PID are more likely to suffer infertility, ectopic pregnancy, or chronic pelvic pain. […] The diagnosis of PID can be made when all three of the following symptoms are found during a pelvic exam: Lower abdominal tenderness, Tenderness of fallopian tubes and ovaries, Tenderness of the cervix. […] Prompt antibiotic treatment can prevent severe damage to reproductive organs. […] Hospitalization to treat PID may be recommended if the woman (1) is severely ill (e.g., nausea, vomiting, and high fever); (2) is pregnant; (3) does not respond to or cannot take oral medication and needs intravenous antibiotics; (4) has an abscess in the fallopian tube or ovary (tubo-ovarian abscess); or (5) needs to be monitored to be sure that her symptoms are not due to another condition that would require emergency surgery (e.g., appendicitis).

    Many women experience a clinically silent spread of infection to the upper genital tract, which results in subclinical PID. […] However, other studies revealed that a history of pelvic inflammatory disease prior to admission was associated with infertility, preterm labor, chronic pelvic pain and ectopic pregnancy. […] Tubal occlusion was found to be diagnosed in 12.8% of patients after one infection, in 35.5% of patients after two infections, and in 75% of patients after three or more infections. […] Some studies have revealed that the tubal adhesion caused by PID may increase the possibility of ectopic pregnancy. […] PID and amnionitis may result in poor outcomes of subsequent pregnancies. […] Therefore, we conducted a population-based study utilizing data from a nationwide health insurance database, the Taiwan National Health Insurance Research Database (NHIRD), to examine the risk of developing ectopic pregnancy and preterm labor among patients with PID.

    Pelvic inflammatory disease (PID) is a common reproductive health disorder among women of reproductive age. According to the Centers for Disease Control and Prevention (CDC), more than one million women are diagnosed with PID annually, and approximately 2.5 million women of reproductive age have had a PID diagnosis. PID is both a clinical and public health concern due to its potential to result in infertility in undiagnosed or poorly treated cases. This complication affects one in every eight women with a history of PID. Furthermore, PID is associated with other morbidities like chronic pelvic pain, ectopic pregnancy, and recurrence. […] Sexually transmitted infection (STI) screening partner notification and treatment have led to a decline in PID incidence rates. These prevention efforts have also helped reduce the direct and indirect costs of PID and its sequela, estimated to exceed $2000 per-person lifetime cost. The management of PID is slowly evolving, and diagnostic, and treatment guidelines are revised to reflect advances in diagnostics, therapeutics, and clinical research outcomes.

Despite existing recommendations for PID management, many surveys report failure to adhere to these guidelines by some care providers. […] In light of burgeoning antibiotic resistance, efforts to identify the most clinically efficacious and cost-effective approaches to PID treatment remain ongoing. The standardization of PID treatment regimens in these three examples reflects current practice in developed societies. In contrast, PID management is less standardized in low- and middle-income countries, and wide variations in antibiotic use exist due to limitations imposed by cost and underdeveloped healthcare systems.

    M. genitalium is now duly recognized as one of the organisms that play a role in the pathogenesis of PID, and limited testing capabilities and research data hinder proactive action toward its identification and treatment. PID due to M. genitalium is usually asymptomatic or mild, presenting with less severe pelvic pains, less mucopurulent cervical discharge, and fewer markers of inflammation. […] POC testing for STI during asymptomatic infection will allow early intervention and primary prevention of future reproductive sequelae. Adherence support may be necessary to assist patients through treatment. […] PID affects women of reproductive age across the globe. Prevention strategies such as asymptomatic screening have reduced PID prevalence, but non-adherence to treatment guidelines and antimicrobial resistance pose challenges for the management of affected women.

    Our primary interest lies in natural history in the absence of screening for STI infections so we used data for 2002. We developed a homogenous Markov model to describe PID and salpingitis history in women in England. […] We estimated that in England in 2002, 336% of women aged 3544 years had experienced at least one episode of PID (diagnosed or not) and 161% of them had experienced at least one episode of salpingitis (diagnosed or not). Further work is required to assess the degree of overlap between routine data sources for PID and of PID history for women diagnosed with PID.

    The epidemiology of pelvic inflammatory disease (PID) is considered to be a leading cause of morbidity in women but little is known of its epidemiology in England. […] To investigate the epidemiology of PID and explore factors associated with PID. […] The highest burden of disease was seen in general practice where 1.7% of reproductive age women were diagnosed with PID, although management fell below acceptable standards. […] The case-control study showed that PID had the characteristics typical of a sexually transmitted disease. […] Conclusions Diagnostic methods and knowledge of disease aetiology need to be improved if further epidemiological investigations and surveillance initiatives are undertaken.
