Biegunka podróżnych
Objawy

Biegunka podróżnych, dotykająca 30-70% osób podróżujących do krajów o niższym standardzie sanitarnym, definiowana jest jako oddawanie ≥3 luźnych lub wodnistych stolców na dobę, często z towarzyszącymi objawami takimi jak skurcze brzucha, nudności, wymioty i gorączka. Okres inkubacji zależy od czynnika etiologicznego: bakterie (6-72 h), wirusy (6-24 h), pasożyty (1-3 tygodnie), toksyny (kilka godzin). Typowy czas trwania biegunki bakteryjnej wynosi 3-7 dni, wirusowej 2-3 dni, a pasożytniczej może trwać tygodnie lub miesiące. W większości przypadków choroba ma przebieg samoograniczający się, z około 50% pacjentów zdrowiejących w ciągu 48 godzin i średnim czasem trwania 4-5 dni. Cięższe postaci, zwłaszcza z gorączką ≥38°C, krwią w stolcu (dyzenteria) lub odwodnieniem, wymagają interwencji medycznej i często antybiotykoterapii. Szczególną uwagę należy zwrócić na grupy ryzyka: niemowlęta, osoby starsze, immunosupresyjne oraz z chorobami przewlekłymi.

Objawy biegunki podróżnych

Biegunka podróżnych to najczęstsza choroba związana z podróżowaniem, dotykająca od 30% do 70% osób podróżujących do krajów o niższym standardzie sanitarnym. Jest to zaburzenie przewodu pokarmowego, które charakteryzuje się nagłym wystąpieniem luźnych lub wodnistych stolców, spowodowane spożyciem skażonej żywności lub wody.123

Główne objawy

Biegunka podróżnych definiowana jest jako oddawanie trzech lub więcej luźnych lub wodnistych stolców w ciągu 24 godzin, często z towarzyszącymi dodatkowymi objawami. Do klasycznych objawów klinicznych należą:123

  • Nagłe oddawanie trzech lub więcej luźnych, wodnistych stolców dziennie
  • Pilna potrzeba wypróżnienia
  • Skurcze i bóle brzucha
  • Nudności
  • Wymioty
  • Gorączka
  • Wzdęcia
  • Ogólne osłabienie

123

Typowo pacjent doświadcza około 4-5 luźnych lub wodnistych wypróżnień dziennie, często z towarzyszącym dyskomfortem w jamie brzusznej i ogólnym złym samopoczuciem.12

Początek objawów

Objawy biegunki podróżnych najczęściej pojawiają się w ciągu pierwszego tygodnia podróży, choć mogą wystąpić w dowolnym momencie podczas wyjazdu, a nawet po powrocie do domu. W przypadku zakażeń bakteryjnych lub wirusowych objawy zwykle pojawiają się w ciągu 6-72 godzin od spożycia skażonej żywności lub wody.1234

Okres inkubacji zależy od czynnika etiologicznego:1

  • Zatrucia toksynami: objawy w ciągu kilku godzin
  • Zakażenia bakteryjne i wirusowe: 6-96 godzin
  • Zakażenia pasożytnicze: 1-3 tygodnie (wyjątek Cyclospora cayetanensis: 2-14 dni)

12

Stopnie nasilenia objawów

Biegunkę podróżnych można podzielić ze względu na nasilenie objawów:12

  • Łagodna: tolerowalna biegunka, która nie zaburza planowanych aktywności
  • Umiarkowana: biegunka, która wpływa na planowane aktywności i jest wyraźnie uciążliwa
  • Ciężka: biegunka uniemożliwiająca wykonywanie planowanych czynności, często z gorączką i/lub krwią w stolcu (dyzenteria)

12

Przebieg biegunki podróżnych

Czas trwania choroby

W większości przypadków biegunka podróżnych jest schorzeniem samoograniczającym się, które ustępuje bez leczenia w ciągu kilku dni. Typowo trwa:123

  • Biegunka bakteryjna: 3-7 dni bez leczenia
  • Biegunka wirusowa: 2-3 dni
  • Większość przypadków: ustępuje w ciągu 5 dni bez leczenia

123

Badania wskazują, że około 50% pacjentów samoistnie wraca do zdrowia w ciągu 48 godzin, a u większości chorych średni czas trwania biegunki wynosi 4-5 dni.1 Jednak u niektórych osób objawy mogą utrzymywać się dłużej, a nawet mogą wystąpić wielokrotne epizody podczas jednego wyjazdu.12

Biegunka podróżnych o przedłużonym przebiegu

W niektórych przypadkach biegunka może utrzymywać się dłużej i być bardziej nasilona, zwłaszcza gdy wywołana jest określonymi bakteriami lub pasożytami. Biegunkę trwającą ponad 14 dni określa się jako przetrwałą biegunkę podróżnych.123

Przedłużające się objawy mogą być spowodowane:12

123

W przypadku zakażeń pasożytniczych, takich jak giardioza, objawy mogą utrzymywać się przez tygodnie lub nawet miesiące bez odpowiedniego leczenia.12

Powikłania biegunki podróżnych

Najczęstszym i najpoważniejszym powikłaniem biegunki podróżnych jest odwodnienie, szczególnie u dzieci i osób starszych. Objawy odwodnienia, które wymagają natychmiastowej interwencji medycznej, to:123

  • Suchość w ustach
  • Zmniejszone wydzielanie moczu (u niemowląt: mniej mokrych pieluch)
  • Płacz bez łez (u dzieci)
  • Zapadnięte oczy
  • Skurcze mięśni
  • Zawroty głowy, omdlenia
  • Silne osłabienie, senność
  • Ciemny mocz

123

Odwodnienie może zaburzać działanie przyjmowanych leków, w tym doustnych środków antykoncepcyjnych czy leków przeciwmalarycznych.12

Powikłania długoterminowe

Czasami po przebyciu ostrego epizodu biegunki podróżnych mogą wystąpić przewlekłe zaburzenia żołądkowo-jelitowe:12

123

Warianty kliniczne biegunki podróżnych

Dyzenteria

Dyzenteria to każda biegunka z obecnością krwi w stolcu. Jest zwykle cięższa i bardziej przedłużająca się niż typowa wodnista biegunka podróżnych i wymaga leczenia antybiotykami.1

Charakterystyka dysenterii:12

  • Początkowo niespecyficzne objawy grypopodobne
  • Wysoka gorączka (38°C i więcej)
  • Bóle głowy, bóle całego ciała
  • Początkowo wodnista biegunka w dużych ilościach
  • Później krew i śluz w stolcu

12

Dyzenteria najczęściej wywoływana jest przez bakterie takie jak Shigella, Salmonella i Campylobacter.1

Zatrucie pokarmowe

Zatrucie pokarmowe objawia się nagłymi nudnościami i obfitymi wymiotami wkrótce po spożyciu posiłku. Wymioty są głównym objawem, często z towarzyszącymi skurczami żołądka i później wodnistą biegunką.1

Biegunka spowodowana pasożytami

Biegunka wywołana przez pasożyty ma zwykle bardziej stopniowy początek łagodnych objawów, z 2-5 luźnymi stolcami dziennie. Charakterystyczne cechy:1

  • Giardioza (zakażenie Giardia duodenalis): wybuchowa biegunka z wzdęciami i odbijaniem o zapachu zgniłych jaj, wiatry, może utrzymywać się tygodniami bez leczenia1
  • Amebioza (zakażenie Entamoeba histolytica): zakres objawów od łagodnej biegunki do czerwonki, może być bardziej nasilona i przedłużona u osób z osłabionym układem odpornościowym1
  • Kryptosporydioza i Cyklosporioza: przewlekła wodnista biegunka1

Kiedy należy skonsultować się z lekarzem

Większość przypadków biegunki podróżnych ustępuje samoistnie, jednak w niektórych sytuacjach konieczna jest konsultacja lekarska. Należy szukać pomocy medycznej w przypadku:12

Objawy alarmowe u dorosłych

  • Biegunka trwająca dłużej niż 2 dni bez poprawy
  • Gorączka powyżej 39°C
  • Krwawa lub czarna biegunka
  • Silny ból brzucha lub odbytnicy
  • Utrzymujące się wymioty przez ponad 4 godziny
  • Objawy odwodnienia
  • Brak poprawy po zastosowaniu antybiotyków

1234

Objawy alarmowe u dzieci

U dzieci biegunka podróżnych może prowadzić do szybkiego odwodnienia, dlatego należy zachować szczególną ostrożność i skontaktować się z lekarzem, jeśli dziecko ma:12

  • Uporczywe wymioty
  • Gorączkę powyżej 39°C
  • Krwawą biegunkę lub ciężką biegunkę
  • Suchość w ustach lub płacz bez łez
  • Nietypową senność, ospałość lub brak reakcji
  • Zmniejszoną ilość moczu, w tym mniej mokrych pieluch u niemowląt

123

Przebieg kliniczny biegunki podróżnych ma tendencję do większej ciężkości i przedłużonego czasu trwania u dzieci, szczególnie u tych poniżej 2 roku życia.12

Biegunka podróżnych u osób w grupach ryzyka

Szczególną uwagę należy zwrócić na biegunkę podróżnych u:1

  • Niemowląt i małych dzieci
  • Osób starszych
  • Osób z osłabionym układem odpornościowym
  • Osób z przewlekłymi chorobami

12

W tych grupach biegunka podróżnych może prowadzić do poważniejszych powikłań, a odwodnienie może nastąpić szybciej i być trudniejsze do wykrycia.1

Podsumowanie objawów i przebiegu

Biegunka podróżnych to częsta dolegliwość, która dotyka od 30% do 70% podróżujących do krajów rozwijających się. Charakteryzuje się nagłym początkiem i oddawaniem co najmniej trzech luźnych lub wodnistych stolców na dobę, często z towarzyszącymi skurczami brzucha, nudnościami, wymiotami i gorączką.12

W większości przypadków biegunka podróżnych jest łagodnym, samoograniczającym się schorzeniem, które ustępuje bez leczenia w ciągu 3-7 dni. Niektóre przypadki mogą jednak być cięższe, trwać dłużej lub prowadzić do powikłań, takich jak odwodnienie.12

Najważniejsze działanie w przypadku biegunki podróżnych to zapobieganie odwodnieniu poprzez uzupełnianie utraconych płynów i elektrolitów. W przypadku ciężkich objawów, takich jak krwawa biegunka, wysoka gorączka lub objawy odwodnienia, należy szukać pomocy medycznej.123

Czynnik etiologiczny Okres inkubacji Czas trwania Charakterystyczne objawy
Bakterie 6-72 godzin 3-7 dni Wodnista biegunka, skurcze brzucha, gorączka
Wirusy 6-24 godzin 2-3 dni Wymioty (bardziej nasilone), biegunka, bóle głowy
Pasożyty 1-3 tygodnie Tygodnie-miesiące Powolny początek, przewlekła biegunka, wzdęcia
Toksyny Kilka godzin 1-2 dni Nagłe wymioty, później biegunka

    Traveler’s diarrhea is a digestive tract disorder that commonly causes loose stools and stomach cramps. It’s caused by eating contaminated food or drinking contaminated water. Fortunately, traveler’s diarrhea usually isn’t serious in most people it’s just unpleasant. […] Traveler’s diarrhea may begin suddenly during your trip or shortly after you return home. Most people improve within 1 to 2 days without treatment and recover completely within a week. However, you can have multiple episodes of traveler’s diarrhea during one trip. […] The most common symptoms of traveler’s diarrhea are: Suddenly passing three or more looser watery stools a day. An urgent need to pass stool. Stomach cramps. Nausea. Vomiting. Fever. […] Sometimes, people experience moderate to severe dehydration, ongoing vomiting, a high fever, bloody stools, or severe pain in the belly or rectum. If you or your child experiences any of these symptoms or if the diarrhea lasts longer than a few days, it’s time to see a healthcare professional.

    http://www.travelandimmunizationclinic.com/advice-for-travelers-on-travelers-diarrhea/
    Traveler’s diarrhea is considered the most predictable illness related to travel. The majority of cases of Traveler’s diarrhea begin all of the sudden. The illness typically results in an increase in the weight, volume and frequency of a person’s stool. An altered stool consistency is also quite common. In most cases, a traveler will suffer from four or five watery or loose bowel movements per day. Other symptoms include malaise, urgency, fever, bloating, abdominal cramps, diarrhea, vomiting, and nausea. […] In most cases, the issue will be benign and resolve itself within a day or two without having to seek treatment.

    The incubation period between exposure and clinical presentation can provide clues to etiology. Toxin-mediated illness, for example, generally causes symptoms within a few hours. By contrast, illnesses caused by bacterial and viral pathogens have incubation periods of 6-96 hours. In general, illnesses due to protozoal pathogens have longer incubation periods (1-2 weeks), rarely presenting in the first few days of travel. An exception is Cyclospora cayetanensis infection, in which symptoms can present quickly (2-14 days).

    The cornerstone of treating travellers diarrhea is maintaining proper hydration. While staying hydrated is usually sufficient, taking medication may be necessary in more concerning cases. […] Diarrhea is considered mild if it is tolerable and does not interfere with planned activities. Mild symptoms usually resolve on their own and do not require any special treatment. However, if the need to use the restroom becomes too frequent or if you dont have easy access to facilities (such as during a journey), these anti-diarrheal medications can be used: Bismuth subsalicylate (e.g., Pepto-Bismol) […] Antibiotics are not recommended for mild diarrhea. […] Diarrhea that is intense enough to interfere with planned activities is considered moderate. For self-treatment of these cases, the use of loperamide (e.g., Imodium) as monotherapy, meaning taken alone, is recommended.

    Travelers’ diarrhea (TD) is the most predictable travel-related illness. Attack rates range from 30% to 70% of travelers during a 2-week period, depending on the destination and season of travel. TD is a clinical syndrome that can result from a variety of intestinal pathogens. Bacterial and viral TD present with the sudden onset of symptoms that can range from mild cramps and urgent loose stools to severe abdominal pain, bloody diarrhea, fever, and vomiting; with norovirus, vomiting can be more prominent. Diarrhea caused by protozoa (e.g., Cryptosporidium, Giardia duodenalis) may have a more gradual onset of low-grade symptoms, with 25 loose stools per day. Untreated, bacterial diarrhea usually lasts 3-7 days. Viral diarrhea generally lasts 2-3 days. Protozoal diarrhea can persist for weeks to months without treatment. An acute (less than 2 weeks) bout of TD can lead to persistent enteric symptoms, even in the absence of continued infection. This presentation is commonly referred to as post-infectious irritable bowel syndrome.

    Dr. Alexander Leung noted in Travelers Diarrhea: A Clinical Review, Travelers diarrhea is usually self-limited. If left untreated, approximately 50% of the patients are spontaneously cured in 48 hours and, in the majority of patients, the average duration of diarrhea is 4 to 5 days. […] He does add that the clinical course tends to be more severe and prolonged in children, especially those younger than 2 years of age.

    Traveler’s diarrhea usually goes away on its own within several days. Symptoms may last longer and be more severe if it’s caused by certain bacteria or parasites. In such cases, you may need prescription medicines to help you get better. […] If you’re an adult, see your doctor if: Your diarrhea lasts beyond two days. You become dehydrated. You have severe stomach or rectal pain. You have bloody or black stools. You have a fever above 102 F (39 C). […] Be especially cautious with children because traveler’s diarrhea can cause severe dehydration in a short time. Call a doctor if your child is sick and has any of the following symptoms: Ongoing vomiting. A fever of 102 F (39 C) or more. Bloody stools or severe diarrhea. Dry mouth or crying without tears. Signs of being unusually sleepy, drowsy or unresponsive. Decreased volume of urine, including fewer wet diapers in infants.

    While most travelers will have onset and resolution of diarrhea during their trip, some will present with symptoms after return. […] Although most cases of travelers’ diarrhea (TD) are acute and self-limited, some people develop persistent (14 days) gastrointestinal (GI) symptoms. […] Most cases of TD are the result of bacterial or viral infection and are short-lived and self-limited. […] In addition to prolonged symptoms of typical pathogens among immunosuppressed persons and sequential infection with different pathogens, ongoing infection with parasites can cause prolonged diarrheal symptoms. […] While individual bacterial infections rarely cause persistent symptoms, travelers infected with bacteria known to cause mucosal inflammation, such as Campylobacter spp., Shigella spp., or Salmonella spp., as well as diarrheagenic Escherichia coli, can experience persistent diarrhea, including cases where the organism may be resistant against antibiotics commonly used for empiric treatment of TD.
  • #1 Traveler’s diarrhea – Diagnosis and treatment – Mayo Clinic
    https://www.mayoclinic.org/diseases-conditions/travelers-diarrhea/diagnosis-treatment/drc-20352188
    Diagnosing traveler’s diarrhea typically involves taking a medical and travel history. A physical exam may be done to check for signs of dehydration. If symptoms are serious or don’t resolve on their own, a stool sample may be done to check for microorganisms. […] Traveler’s diarrhea may get better without any treatment. But while you’re waiting, it’s important to try to stay hydrated with safe liquids, such as bottled water or water with electrolytes such as an oral rehydration solution. […] Dehydration is the most likely complication of traveler’s diarrhea, so it’s important to try to stay well hydrated. […] If dehydration symptoms such as dry mouth, intense thirst, little or no urination, dizziness, or extreme weakness don’t improve, seek medical care right away. Oral rehydration solutions are intended only for urgent short-term use.

    Traveler’s diarrhea can be mild to severe. Most people who develop traveler’s diarrhea experience symptoms within the first 2 weeks, and often within 2 to 3 days, of arriving in a developing area. Symptoms include: […] Fever, vomiting, and stools with blood or mucus. These symptoms mean you have serious diarrhea, which is more likely to lead to problems with dehydration. Dehydration may alter the effect of any medicines being taken, such as oral contraceptives or antimalarials.

    Symptoms may include watery diarrhea, nausea, or abdominal cramping. […] Disease may be more severe and prolonged in immunocompromised individuals. […] Persistent TD also has been associated with tropical sprue and Brainerd diarrhea, both of which are believed to be caused by an infectious agent, although their culprit pathogens have yet to be identified. […] In some cases, persistent symptoms relate to chronic underlying GI disease or to a susceptibility unmasked by the enteric infection. […] Most prominent among these is celiac disease, a systemic disease manifesting primarily with small bowel changes. […] In genetically susceptible people, exposure to antigens found in wheat causes villous atrophy, crypt hyperplasia, and malabsorption. […] After an acute diarrheal infection, patients might experience a temporary enteropathy characterized by villous atrophy, decreased absorptive surface area, and disaccharidase deficiencies, which can lead to osmotic diarrhea, particularly after consuming large amounts of fructose, lactose, sorbitol, or sucrose.

    Traveller’s diarrhoea is generally a short, mild illness lasting on average about three to five days. […] The usual scenario is that the illness starts a few days after you arrive, and involves up to six episodes of loose faeces a day. You may feel sorry for yourself, but it doesn’t usually make you feel particularly unwell. […] The illness generally resolves itself in a few days (on average three to five). It rarely causes severe dehydration, although the potential is always there and is more of a risk in children and older travellers. […] Dysentery is any diarrhoea with blood in it. It can be more severe and protracted than the more common watery diarrhoea described earlier, and usually needs antibiotic treatment. […] Dysentery usually begins with nonspecific flu-like symptoms, and you often feel really rough, with headache, high fever (38C and above), and aches and pains all over.

    Traveller’s diarrhoea symptoms […] Most pathogens cause mild self-limiting diarrhoea for less than 72 hours. […] Diarrhoea lasting for longer than 14 days suggests more unusual organisms and testing for Giardia, Entamoeba, Cyclospora and Cryptosporidium species is required. […] Bloody diarrhoea (dysentery) occurs more commonly with some pathogens (Salmonella, Shigella and Campylobacter species). Some pain may accompany infection with Campylobacter spp. […] Diarrhoea caused by enterotoxigenic E. coli is usually watery and profuse. It may be preceded by abdominal pains, nausea and general malaise. […] G. lamblia is often associated with bloating and burping. […] In children aged under 5 years rotavirus is a common pathogen.

    To start with, the diarrhoea is often watery and in large quantities; later it gets less and you start to notice blood and mucus (slime) mixed in your faeces. […] If you suddenly get an attack of nausea and profuse vomiting soon after eating, it’s probably due to food poisoning. […] Vomiting is the main symptom, often with stomach cramps and some watery diarrhoea later. […] If diarrhoea strikes, you don’t necessarily need to reach for your medical kit for „stoppers” which paralyses the gut and stops the flow, or for antibiotics; there are some simple measures it’s worth taking. […] The most important treatment measure is to avoid dehydration by replacing lost fluids and salts, which you should start doing straight away.

    Dysentery – any diarrhoea containing blood or mucous. […] Giardia – explosive diarrhoea with bloating and rotten egg gas-like burping and flatulence. […] Most cases are resolved spontaneously with fluid replacement within 3 – 4 days. Persistent or complicated diarrhoea may require further drug treatment. […] Dehydration is the most serious consequence associated with most forms of travellers diarrhoea. Travellers experiencing TD should drink small amounts of clean water frequently to maintain good urine output (urinating twice a day, preferably more). […] Fluid lost through vomiting or persistent diarrhoea must be replaced to facilitate recovery. […] Aim to maintain clear-coloured urine. Small amounts of dark-coloured urine may indicate the need to increase fluid intake. […] Eating rice may assist early recovery.

    A rare cause of post-travel persistent diarrhea is Yersinia spp., a foodborne bacterial infection which can present as a subacute febrile gastroenteritis. […] Clostridioides difficile-associated diarrhea can occur after or during antibiotic use, including malaria chemoprophylaxis. […] The association between C. difficile and antimicrobial treatment is especially important to consider in patients with persistent TD that seems refractory to multiple courses of empiric antibiotic therapy. […] Giardia duodenalis is the most likely parasitic pathogen to cause persistent diarrhea. […] When giardiasis is left untreated, symptoms can last for months, even in immunocompetent hosts.

    Travelers diarrhea (TD) is the most common travel-related illness. It regularly affects millions of international travelers that visit countries with different sanitization standards and can significantly disrupt travel plans. Evidence suggests that the incidence of TD ranges from 30-70% of travelers, depending on the destination and season of travel. […] Health experts may define TD as 3 or more loose stools in a 24-hour period during a trip abroad to a country with different hygiene practices. It often presents with other symptoms, such as nausea and vomiting. The onset of symptoms may be during or within 10 days of travel and typically lasts for 3-5 days. […] Symptoms of TD may include: frequent loose stools, nausea and vomiting, fever, abdominal pain and discomfort, stools containing blood or mucus. Symptoms typically appear during or shortly after a period of foreign travel. The symptoms and duration of TD may vary depending on the causative agent. For example, without treatment bacterial or viral diarrhea may last for a few days, while protozoal diarrhea can persist for weeks or months.

    Travelers’ diarrhea (TD) is the most predictable travel-related illness. Attack rates range from 30% to 70% of travelers during a 2-week period, depending on the destination and season of travel. TD is a clinical syndrome that can result from a variety of intestinal pathogens. Bacterial and viral TD present with the sudden onset of symptoms that can range from mild cramps and urgent loose stools to severe abdominal pain, bloody diarrhea, fever, and vomiting; with norovirus, vomiting can be more prominent. Diarrhea caused by protozoa (e.g., Cryptosporidium, Giardia duodenalis) may have a more gradual onset of low-grade symptoms, with 25 loose stools per day. Untreated, bacterial diarrhea usually lasts 3-7 days. Viral diarrhea generally lasts 2-3 days. Protozoal diarrhea can persist for weeks to months without treatment. An acute (less than 2 weeks) bout of TD can lead to persistent enteric symptoms, even in the absence of continued infection.
