Biegunka związana z antybiotykami
Objawy

Biegunka związana z antybiotykami (AAD) dotyczy około 20% pacjentów stosujących antybiotykoterapię, z częstością wahającą się od 5% do 39%, a u dzieci nawet do 35-80%. Objawy pojawiają się zwykle około tygodnia po rozpoczęciu leczenia, choć mogą wystąpić już po kilku godzinach lub nawet do 10 tygodni po zakończeniu terapii. Klinicznie AAD manifestuje się luźnymi, wodnistymi stolcami (≥3 na dobę) oraz łagodnymi dolegliwościami brzusznymi, które zazwyczaj ustępują samoistnie po zakończeniu antybiotykoterapii. Jednak u 10-25% przypadków AAD jest spowodowana infekcją Clostridioides difficile, charakteryzującą się cięższym przebiegiem: do 10-15 wypróżnień na dobę, bólem brzucha, gorączką <38,3°C, obecnością krwi lub śluzu w stolcu oraz ryzykiem powikłań takich jak pseudomembranous colitis, toxic megacolon, perforacja jelita, sepsa i niewydolność narządowa.

Definicja biegunki związanej z antybiotykami

Biegunka związana z antybiotykami (ang. Antibiotic-associated diarrhea, AAD) odnosi się do występowania luźnych, wodnistych stolców oddawanych trzy lub więcej razy na dobę po przyjęciu leków stosowanych w leczeniu zakażeń bakteryjnych (antybiotyków).12 Szacuje się, że około 1 na 5 osób (20%) przyjmujących antybiotyki rozwija biegunkę związaną z ich stosowaniem, przy czym częstość występowania w niektórych badaniach waha się od 5% do nawet 39% w zależności od populacji i rodzaju antybiotyku.134 U dzieci odsetek ten może być jeszcze wyższy i według niektórych danych sięgać do 35%, a w niektórych grupach nawet do 80%.5

Manifestacja kliniczna objawów

Objawy biegunki związanej z antybiotykami mogą pojawić się w różnym czasie po rozpoczęciu terapii antybiotykowej i mogą wahać się od łagodnych do ciężkich.1

Czas wystąpienia objawów

Biegunka związana z antybiotykami najczęściej rozpoczyna się około tygodnia po rozpoczęciu antybiotykoterapii.12 Warto jednak zauważyć, że objawy mogą pojawić się w różnym czasie:

  • Już w ciągu kilku godzin po rozpoczęciu antybiotykoterapii6
  • W trakcie stosowania antybiotyku (najczęściej pomiędzy 2 a 8 dniem przyjmowania leku)7
  • Dni lub nawet tygodnie po zakończeniu leczenia antybiotykiem1
  • W rzadkich przypadkach nawet do 10 tygodni po zakończeniu antybiotykoterapii8

Objawy łagodnej biegunki związanej z antybiotykami

U większości pacjentów biegunka związana z antybiotykami powoduje łagodne objawy, które obejmują:12

  • Luźne stolce (zmiana konsystencji na bardziej płynną)
  • Częstsze wypróżnienia (3 lub więcej luźnych stolców na dobę)
  • Łagodne dolegliwości brzuszne

210

Objawy te zwykle ustępują samoistnie w ciągu kilku dni po zakończeniu antybiotykoterapii, bez konieczności specjalistycznego leczenia.111

Objawy ciężkiej biegunki związanej z antybiotykami

Poważniejszą i potencjalnie zagrażającą życiu przyczyną biegunki związanej z antybiotykami jest infekcja wywołana przez bakterię Clostridioides difficile (dawniej Clostridium difficile, C. diff).12 Zakażenie C. difficile występuje w około 10-25% przypadków biegunki związanej z antybiotykami i może prowadzić do rozwoju poważnych powikłań.135

Objawy ciężkiej biegunki związanej z zakażeniem C. difficile obejmują:122

  • Nasilona biegunka (do 10-15 wypróżnień na dobę)8
  • Ciężkie odwodnienie
  • Silny ból i skurcze w dolnej części brzucha
  • Gorączka o niskim nasileniu (zazwyczaj poniżej 38,3°C)
  • Nudności
  • Utrata apetytu
  • Obecność krwi lub śluzu w stolcu8
  • Utrata masy ciała8

Progresja choroby i rozwój ciężkiej postaci

W rzadkich przypadkach biegunka związana z zakażeniem C. difficile może prowadzić do poważnych powikłań, takich jak:16

  • Rzekomobłoniaste zapalenie jelita grubego (pseudomembranous colitis) – stan zapalny okrężnicy charakteryzujący się obecnością charakterystycznych białawych błon na śluzówce jelita1710
  • Toksyczne rozdęcie okrężnicy (toxic megacolon) – potencjalnie zagrażające życiu rozdęcie okrężnicy1610
  • Perforacja jelita – przerwanie ciągłości ściany jelita, mogące prowadzić do ogólnoustrojowego zakażenia16
  • Posocznica – ogólnoustrojowe zakażenie16
  • Niewydolność narządowa16

18

Objawami wskazującymi na rozwój tych ciężkich powikłań mogą być:1619

  • Wzdęcie brzucha
  • Silny ból brzucha
  • Wysoka gorączka (powyżej 38,3°C)
  • Obfita biegunka
  • Przyspieszone tętno
  • Niskie ciśnienie tętnicze
  • Objawy odwodnienia (bardzo suche usta, intensywne pragnienie, skąpomocz lub bezmocz, zawroty głowy, osłabienie)20

21

Patogeneza i przebieg biegunki związanej z antybiotykami

Biegunka związana z antybiotykami występuje w wyniku zaburzenia równowagi mikroflory jelitowej spowodowanego działaniem antybiotyków.922

Mechanizm powstawania

W warunkach prawidłowych w jelitach człowieka żyje wiele różnych gatunków bakterii, które tworzą złożony ekosystem. Antybiotyki mogą drastycznie zmienić tę równowagę poprzez:9

  • Zabijanie zarówno „dobrych”, jak i „złych” bakterii w jelitach
  • Zmniejszenie różnorodności mikrobiologicznej
  • Zaburzenie naturalnej funkcji ochronnej mikrobioty jelitowej
  • Upośledzenie wchłaniania węglowodanów, co prowadzi do wydzielania wody i luźniejszych stolców23

10

W większości przypadków jest to przejściowe zaburzenie, które ustępuje po zakończeniu antybiotykoterapii. Jednak w niektórych przypadkach, szczególnie przy stosowaniu antybiotyków o szerokim spektrum działania, może dojść do znacznego zmniejszenia liczby bakterii komensalnych i nadmiernego namnożenia bakterii patogennych, takich jak C. difficile.923

Czynniki sprzyjające rozwojowi biegunki

Biegunka związana z antybiotykami może wystąpić u każdego, kto przyjmuje antybiotyk, jednak pewne czynniki zwiększają ryzyko jej wystąpienia:20

  • Wcześniejsze epizody biegunki związanej z antybiotykami2013
  • Długotrwała antybiotykoterapia2013
  • Jednoczesne stosowanie więcej niż jednego antybiotyku20
  • Wiek poniżej 3 lat oraz wiek powyżej 65 lat1318
  • Dożylna droga podania antybiotyku13
  • Rodzaj infekcji (zwiększone ryzyko przy zakażeniach dolnych dróg oddechowych i dróg moczowych)13
  • Hospitalizacja8
  • Osłabiony układ odpornościowy20

24

Niektóre antybiotyki częściej powodują biegunkę niż inne. Do grupy podwyższonego ryzyka należą:15

525

Przebieg czasowy choroby

Typowy przebieg biegunki związanej z antybiotykami można podzielić na następujące etapy:

  1. Początek objawów: Najczęściej około tygodnia po rozpoczęciu antybiotykoterapii, choć może pojawić się wcześniej lub później12
  2. Faza ostra: Charakteryzuje się luźnymi, wodnistymi stolcami oddawanymi kilka razy dziennie, czasem z towarzyszącym dyskomfortem brzusznym2
  3. Ustąpienie objawów: W przypadku łagodnej biegunki objawy zwykle ustępują samoistnie w ciągu kilku dni po zakończeniu antybiotykoterapii11

W przypadku zakażenia C. difficile biegunka zazwyczaj zaczyna ustępować w ciągu pierwszych 72 godzin od rozpoczęcia ukierunkowanego leczenia przeciwbakteryjnego, jednak u niektórych pacjentów mogą rozwinąć się ciężkie objawy z dłuższym czasem zdrowienia.26 Co istotne, biegunka związana z C. difficile może nawracać mimo odpowiedniego początkowego leczenia u około 15-35% pacjentów w ciągu ośmiu tygodni.2618

Objawy alarmowe wymagające natychmiastowej interwencji

Należy natychmiast skontaktować się z lekarzem, jeśli podczas lub po antybiotykoterapii wystąpią następujące objawy:926

  • Więcej niż pięć luźnych stolców lub epizodów biegunki na dobę
  • Obfita, wodnista biegunka
  • Gorączka
  • Ból brzucha lub tkliwość brzucha
  • Krew lub ropa w stolcu
  • Oznaki odwodnienia (bardzo suche usta, intensywne pragnienie, skąpomocz lub bezmocz, zawroty głowy, osłabienie)
  • Wzdęcie brzucha
  • Przyspieszone tętno

1227282930

Oznaki odwodnienia

Jednym z najczęstszych powikłań biegunki jest utrata płynów i elektrolitów, prowadząca do odwodnienia.20 Szczególnie narażone są niemowlęta, małe dzieci i osoby starsze.1431 Objawy odwodnienia, które wymagają pilnej interwencji medycznej, to:20

  • Bardzo suche usta
  • Intensywne pragnienie
  • Skąpomocz lub bezmocz
  • Zawroty głowy
  • Osłabienie
  • Zmniejszona czujność i funkcje poznawcze
  • Bóle głowy
  • Drażliwość
  • Przyspieszona czynność serca
  • Zmniejszona siła mięśniowa i wytrzymałość

31

Ciężkie odwodnienie może prowadzić do uszkodzenia nerek i być zagrażające dla życia.3231

Różnice między łagodną a ciężką postacią biegunki związanej z antybiotykami

Poniższa tabela przedstawia kluczowe różnice między łagodną biegunką związaną z antybiotykami a ciężką postacią wywołaną zakażeniem C. difficile:

Cecha Łagodna biegunka związana z antybiotykami Ciężka biegunka (zakażenie C. difficile)
Częstość wypróżnień 3-5 razy dziennie Do 10-15 razy dziennie
Konsystencja stolca Luźne, wodniste Obfite, wodniste, czasem z krwią lub śluzem
Ból brzucha Łagodny dyskomfort Silny ból i skurcze
Gorączka Zwykle nieobecna Niska lub wysoka
Objawy ogólne Minimalne Nudności, utrata apetytu, osłabienie
Czas ustąpienia po zakończeniu antybiotykoterapii Kilka dni Może utrzymywać się dłużej, wymaga leczenia
Ryzyko powikłań Niskie Wysokie (odwodnienie, zapalenie okrężnicy, toksyczne rozdęcie okrężnicy)
Ryzyko nawrotu Niskie 15-35% pacjentów

892621

Szczególne grupy ryzyka

Biegunka związana z antybiotykami u dzieci

Biegunka związana z antybiotykami występuje częściej u dzieci poniżej 2 roku życia, gdzie odsetek zachorowań może sięgać nawet 18%.733 U dzieci biegunka zazwyczaj utrzymuje się od 1 do 7 dni, choć czasem może trwać od pierwszego dnia antybiotykoterapii aż do kilku tygodni po jej zakończeniu.7

Objawy biegunki u dzieci mogą obejmować:34

  • Wzdęcie brzucha i ból brzucha
  • Lekko opuchnięty brzuch
  • Częste wypróżnienia (nawet 15-20 razy dziennie)
  • Luźne, śluzowate stolce, czasem zielonkawe lub żółtawe
  • Pieniące się stolce lub zawierające niestrawione resztki pokarmowe
  • Krew lub śluz w kale (w cięższych przypadkach)
  • Zaczerwienienie skóry wokół odbytu z powodu drażniącego działania kwaśnego stolca

Głównym powikłaniem biegunki związanej z antybiotykami u dzieci jest odwodnienie, które występuje częściej u niemowląt poniżej 12 miesiąca życia.7 Należy natychmiast skontaktować się z lekarzem, jeśli u dziecka wystąpi ciężka biegunka, nowa gorączka, krew w kale, skrajne zmęczenie i brak przyjmowania płynów lub oznaki odwodnienia, takie jak zmniejszona ilość moczu, drażliwość, zmęczenie i suchość w jamie ustnej.735

Biegunka związana z antybiotykami u osób starszych i hospitalizowanych

Osoby starsze (powyżej 65 roku życia) oraz pacjenci hospitalizowani są szczególnie narażeni na rozwój biegunki związanej z antybiotykami, zwłaszcza wywołanej przez C. difficile.818 W tej grupie pacjentów ryzyko ciężkiego przebiegu i powikłań jest wyższe z powodu:36

  • Osłabionego układu odpornościowego
  • Chorób współistniejących
  • Wcześniejszych hospitalizacji
  • Zażywania wielu leków

618

U pacjentów przebywających na oddziałach intensywnej terapii czynnikami zwiększającymi ryzyko wystąpienia biegunki związanej z antybiotykami są: starszy wiek, dłuższy czas pobytu na OIT, czas stosowania inhibitorów pompy protonowej oraz czas trwania antybiotykoterapii.24

Podsumowanie progresji i objawów

Biegunka związana z antybiotykami to częste powikłanie antybiotykoterapii, występujące u około 20% pacjentów przyjmujących antybiotyki.1 Objawy najczęściej pojawiają się około tygodnia po rozpoczęciu leczenia, ale mogą wystąpić w każdym momencie podczas terapii lub nawet kilka tygodni po jej zakończeniu.12

W większości przypadków biegunka związana z antybiotykami ma przebieg łagodny i samoograniczający się, ustępując w ciągu kilku dni po zakończeniu antybiotykoterapii.1 Jednak u niektórych pacjentów, szczególnie tych z grupy podwyższonego ryzyka, może rozwinąć się ciężka postać choroby związana z zakażeniem C. difficile, która wymaga specjalistycznego leczenia i może prowadzić do poważnych powikłań.12

Ważne jest, aby monitorować objawy podczas antybiotykoterapii i niezwłocznie skonsultować się z lekarzem w przypadku wystąpienia objawów alarmowych, takich jak nasilona biegunka, gorączka, ból brzucha, krew w stolcu czy oznaki odwodnienia.926

    Antibiotic-associated diarrhea refers to passing loose, watery stools three or more times a day after taking medications used to treat bacterial infections (antibiotics). […] About 1 in 5 people who take antibiotics develop antibiotic-associated diarrhea. Most often, antibiotic-associated diarrhea is mild and requires no treatment. The diarrhea typically clears up within a few days after you stop taking the antibiotic. More-serious antibiotic-associated diarrhea requires stopping or sometimes switching antibiotics. […] For most people, antibiotic-associated diarrhea causes mild signs and symptoms, such as: Loose stools, More-frequent bowel movements. […] Antibiotic-associated diarrhea is likely to begin about a week after you start taking an antibiotic. Sometimes, however, diarrhea and other symptoms don’t appear until days or even weeks after you’ve finished antibiotic treatment.

    Antibiotic-associated diarrhoea is among the most common adverse events related to antibiotic use. Most cases are mild, but Clostridium difficile infection causes a spectrum of disease, ranging from occasional diarrhoea to colitis, toxic megacolon, and potentially death. […] Most cases of AAD are mild and self-limiting, and are associated with negative stool culture results. Given the widespread use of antibiotics, it is not surprising that this condition is so common, affecting 539% of people treated with antibiotics. […] The range of clinical disease that can occur in CDI is wide: diarrhoea and fever occur in almost all cases, but the most severe cases are characterised by colitis, toxic megacolon (dilatation of the colon, with the risk of perforation), multi-organ failure, or even death.

    Antibiotics are safe for most people, it has been proven that a common side effect of the treatment is diarrhea. Symptoms can range from mild abdominal discomfort, watery diarrhea, to severe colitis and even death. […] According to several studies, diarrhea occurs between 5% and 39% of patients receiving antibiotics, depending on the population and the type of antibiotic. […] The major cause of antibiotic-associated diarrhea is infection with Clostridium difficile bacteria. […] Illness from C. difficile typically occurs after use of antibiotic medications and has become more frequent, more severe and more difficult to treat. […] Patients suffering from Inflammatory Bowel Disease, both ulcerative colitis and Crohns disease, are also particularly vulnerable to C. difficile infection and physicians recommend that their stools be tested whenever disease flares up with significant diarrhea. […] C. difficile infection recurs in up to 25% of the patients even after initial successful treatment, requiring another round of treatment with antibiotics.

    Among children this percentage can reach up to 80%. Most of the time, the diarrhea is purely functional, caused by the antibiotic-induced dysbiosis. It is usually of mild intensity and is self-limiting, lasting 1-5 days. Antibiotics displaying a broader spectrum of antimicrobial activity like clindamycin, cephalosporins, and ampicillin/amoxicillin are associated with higher rates of diarrhea. […] In 10 to 20% of cases, diarrhea results from infection with Clostridioides difficile (formerly known as Clostridium difficile) colonizing the microbiota. […] Nearly 1/3 of AAD cases are due to C. difficile. […] The highest risk of developing CDI was observed for cephalosporins (from 2nd to 4th generations), clindamycin, carbapenems, trimethoprim sulfonamide, fluoroquinolones and penicillin combinations.

    https://bhm.scholasticahq.com/article/39745-antibiotic-associated-diarrhea-beyond-c-difficile-a-scoping-review
    A common complication of antibiotic use is the development of diarrheal illness. The pathogenesis of antibiotic associated diarrhea (AAD) may be mediated through alteration of intestinal microbiota, overgrowth of opportunistic pathogens, and direct drug toxicity on the gut. […] Antibiotic associated diarrhea (AAD) is defined as passage of three or more unformed stools per day beginning anywhere from within a few hours up to 8 weeks after starting antibiotic therapy. […] The frequency of AAD has been reported to occur in 5-35% persons exposed to antimicrobials and varies upon the class of antibiotics received, health of the host and exposure to pathogens. […] AAD may range from mild, self-limiting illness to fulminant, pseudomembranous colitis that can be life threatening. […] The likely pathogenesis of AAD includes alteration of intestinal microbiota, direct drug toxicity on the gut and development of a superinfection by a pathogenic microbe.

    https://bhm.scholasticahq.com/article/39745-antibiotic-associated-diarrhea-beyond-c-difficile-a-scoping-review
    Numerous adverse effects to antibiotics have been associated with changes in the intestinal microbiota including diarrhea, acquisition of CDI, emergence of antibiotic resistant strains of enteric pathogens, and a decline in colonization resistance. […] C. difficile has been proven to cause AAD. C. difficile AAD is reported to be 4 and 60 times more common than C. perfringens or S. aureus, respectively. […] Clinical manifestations in CDI range from short-term colonization, acute diarrhea, fulminant diarrhea, which may be associated with pseudomembranous colitis and leukocytosis and may lead to death, and recurrent CDI (rCDI). […] The severity of illness may depend on risk factors such as age, host immune status, number of prior hospitalizations and presence of co-morbidities. […] S. aureus induced AAD was identified early in the antibiotic era as a cause of AAD in hospitalized patients.
  • #7 Antibiotic-associated diarrhea
    https://www.aboutkidshealth.ca/antibiotic-associated-diarrhea
    Diarrhea is common in children taking antibiotics. In most cases, it is mild. […] One in five children who take antibiotics will develop diarrhea. It is more common in children aged under two years and can occur with any type of antibiotic. […] For most children, antibiotic-associated diarrhea is mild. […] If a child has antibiotic-associated diarrhea, they will have loose or watery stools while taking antibiotics. Most times, the diarrhea lasts between one and seven days. […] Diarrhea usually begins between the second and eighth day of taking an antibiotic. Sometimes, however, it can last from the first day of antibiotics until a few weeks after your child finishes them. […] One of the main complications of antibiotic-associated diarrhea is dehydration. This is more likely to occur in babies less than 12 months old. If your child loses a lot of fluids, make sure they drink enough to replace them.
  • #7 Antibiotic-associated diarrhea
    https://www.aboutkidshealth.ca/antibiotic-associated-diarrhea
    Although rare, another complication of antibiotic use is inflammation (pain or swelling) of the large intestine. Signs of inflammation include severe diarrhea that may contain blood or mucus, fever, stomach pain, and extreme weakness. […] Call your child’s regular health-care provider right away if your child has severe diarrhea, has a new fever, has blood in the stool, is very tired and not drinking, or is showing signs of dehydration, such as less urine, crankiness, fatigue and dry mouth.

    https://www.uptodate.com/contents/antibiotic-associated-diarrhea-caused-by-clostridioides-difficile-beyond-the-basics/print
    Antibiotic-associated diarrhea refers to diarrhea that develops in a person who is taking or recently took antibiotics. One of the most serious causes of antibiotic-associated diarrhea is infection with a bacterium called Clostridioides difficile. C. difficile infections are common, with approximately 500,000 cases per year in the United States. Infection is most common in people who are hospitalized, producing disease in more than 8 hospitalized patients per 1000 (0.9 percent) in 2008 in the United States. […] Symptoms of C. difficile may begin during antibiotic therapy or 5 to 10 days after the antibiotic is stopped; less commonly, symptoms do not develop until as late as 10 weeks later. The most common symptoms include diarrhea (three or more unformed bowel movements per day), or diarrhea associated with abdominal cramping. In more severe cases, patients may develop profuse watery diarrhea (up to 10 to 15 times per day), blood or pus in the stool, dehydration, abdominal tenderness and cramping, fever, nausea, loss of appetite, and weight loss. Anyone who develops one or more of these symptoms should seek medical care as soon as possible.

    https://www.health.harvard.edu/a_to_z/antibiotic-associated-diarrhea-a-to-z
    If you have a more dramatic change in your bowel bacteria, and C. difficile bacteria begin to overgrow, your symptoms can include: watery diarrhea, crampy abdominal pain, abdominal tenderness, fever, pus or blood in your diarrhea (if your illness progresses to C. difficile colitis). […] In some cases, fever and abdominal pain develop several days before diarrhea starts. […] Diarrhea caused by the C. difficile toxin usually starts while you are taking an antibiotic, but the diarrhea may be delayed and start a few weeks after you have stopped taking the medication. […] If you have mild, uncomplicated antibiotic-associated diarrhea, your bowel movements should gradually return to normal once your antibiotic treatment ends. […] C. difficile diarrhea usually begins to subside within the first 72 hours of treatment with medication. However, some people develop severe symptoms with a longer recovery time. C. difficile diarrhea can recur despite adequate initial therapy.

    In healthy people, many different species of bacteria live inside the bowel. […] This can change dramatically when a person begins treatment with an antibiotic. […] In most cases, the result is only a mild case of short-term diarrhea that goes away quickly after the antibiotic treatment ends. […] Occasionally, however, an antibiotic eliminates so many of the bowel’s „good” and harmless bacteria that the aggressive „bad” ones are free to multiply out of control. […] One type of bacteria in particular, a species called Clostridium difficile (C. difficile), can overgrow inside the bowel, producing irritating chemicals that damage the bowel wall and trigger bowel inflammation, called colitis. This can cause abdominal pain, cramps, diarrhea, and fever. In some cases, high-volume, diarrhea is so frequent that the person develops dehydration (very low levels of body water).
  • #9 Antibiotic-Associated Diarrhea – Harvard Health
    https://www.health.harvard.edu/a_to_z/antibiotic-associated-diarrhea-a-to-z
    Call your doctor promptly if you have been taking antibiotics and you develop any of the following symptoms: more than five loose stools or episodes of diarrhea per day, high-volume, watery diarrhea, a fever, abdominal pain or tenderness, blood or pus in your stool. […] Overall, the prognosis is excellent. Almost all adults with mild antibiotic-associated diarrhea recover completely without complications.

    One type of bacteria in particular, a species called Clostridium difficile (C. difficile), can overgrow inside the bowel, producing irritating chemicals that damage the bowel wall and trigger bowel inflammation, called colitis. This can cause abdominal pain, cramps, diarrhea, and fever. In some cases, high-volume, diarrhea is so frequent that the person develops dehydration (very low levels of body water). A more severe complication of C. difficile overgrowth can lead to a type of bowel inflammation called pseudomembranous colitis. Patients with pseudomembranous colitis are at risk of a severely distended colon that stops functioning (toxic megacolon), which can lead to a hole through the bowel wall (bowel perforation). […] Symptoms If you are taking an antibiotic, the medication will cause a mild change in your population of intestinal bacteria that may cause occasional loose stools or mild diarrhea for a few days. These symptoms should stop once your antibiotic treatment ends.
  • #10 Patient Basics: Antibiotic-Associated Diarrhea | 2 Minute Medicine
    https://www.2minutemedicine.com/patient-basics-antibiotic-associated-diarrhea/
    What Is It? In healthy people, many different species of bacteria live inside the bowel. Many are harmless or even helpful to the body, but a few have the potential to be aggressive troublemakers. Under normal circumstances, the “bad” bacteria are far outnumbered, and the bowel’s natural ecological balance keeps them under control. This can change dramatically when a person begins treatment with an antibiotic. This is because antibiotics can kill large numbers of the bowel’s normal bacteria, altering the delicate balance among the various species. In most cases, the result is only a mild case of short-term diarrhea that goes away quickly after the antibiotic treatment ends. Occasionally, however, an antibiotic eliminates so many of the bowel’s “good” and harmless bacteria that the aggressive “bad” ones are free to multiply out of control.

    https://www.mayoclinic.org/diseases-conditions/antibiotic-associated-diarrhea/diagnosis-treatment/drc-20352237
    To diagnose antibiotic-associated diarrhea, your doctor is likely to question you about your health history, including whether you’ve had recent antibiotic treatments. […] Treatment for antibiotic-associated diarrhea depends on the severity of your signs and symptoms. […] If you have mild diarrhea, your symptoms likely will clear up within a few days after your antibiotic treatment ends. […] If you develop C. difficile infection, your doctor will likely stop whatever antibiotic you’re currently taking, and might prescribe antibiotics specifically targeted to kill the C. difficile bacteria causing your diarrhea. […] For people with this type of infection, diarrhea symptoms may return and require repeated treatment. […] To cope with diarrhea, drink enough fluids. […] For infants and children with diarrhea, ask your doctor about using an oral rehydration solution, such as Pedialyte, to replenish fluids and electrolytes.

Antibiotic-associated diarrhea (AAD) was defined as the presence of at least 3 loose/liquid stools within 14 days from antibiotic onset. AAD occurred in 59/289 (20.4%) of patients, with increased risk in children younger than 3 years (relative risk [RR]=4.25), in lower respiratory (RR=2.11) and urinary infections (RR=3.67), intravenous administration (RR=1.81) and previous AAD episodes (RR=1.87). AAD occurred in 20.4% of children, with increased risk at younger age, lower respiratory and urinary tract infections, intravenous treatment and previous AAD. AAD was defined as the presence of 3 or more loose or liquid bowel movements per day during antibiotic treatment (early AAD) or within 14 days from the antibiotics course excluding other etiologies. AAD is a mild and self-limiting (309 days) adverse effect, but it can eventually cause severe electrolyte/fluid imbalance, hospital admission, and pseudomembranous colitis associated with Clostridium difficile infection in 10-25% of cases. The European Society for Pediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) reported AAD in up to 33% children taking antibiotics. A few studies showed an increased rate of AAD in young children, in particular with the use of specific antibiotics such as amoxicillin-clavulanate and ampicillin-sulbactam. The incidence and characteristics of the gastrointestinal manifestations by the different antibiotics are shown in Table 2. The most frequently prescribed antibiotics were protected penicillins, cephalosporins, and macrolides. Overall, 134/289 (46.4%) children were given intravenous antibiotics. In this group, AAD was significantly more frequent compared to oral antibiotic treatment (36/134 vs. 23/155, 26.9% vs. 14.8%; RR, 1.81; 95% CI, 1.13-2.89). We recognized the following as additional risk factors for AAD: Age: AAD was significantly more common among children younger than 3 years and in infants less than 12 months of age; Infection site: We noticed an increased incidence of AAD in cases of lower respiratory infections or urinary infections; Previous AAD: Children reporting previous episodes of AAD were at increased risk of AAD concomitant with a new course of antibiotics.
