Infekcja salmonellowa
Objawy

Salmonelloza to zakażenie przewodu pokarmowego wywołane przez bakterie Salmonella, najczęściej przenoszone przez spożycie surowego lub niedogotowanego mięsa, jaj, produktów mlecznych lub kontakt z zakażonymi zwierzętami. Okres inkubacji wynosi 6-72 godziny, a objawy obejmują biegunkę (często wodnistą, czasem z krwią lub śluzem), gorączkę 38-39°C, bóle brzucha, nudności, wymioty, dreszcze, bóle głowy i mięśni. Objawy utrzymują się zwykle 4-7 dni, choć biegunka może trwać do 10 dni, a pełna rekonwalescencja jelitowa nawet kilka miesięcy. Patogeneza polega na inwazji bakterii do komórek jelitowych, co prowadzi do zapalenia, zaburzeń absorpcji wody i elektrolitów oraz wydzielania płynów do światła jelita, skutkując biegunką i skurczami.

Charakterystyka infekcji salmonellowej

Infekcja salmonellowa (salmonelloza) to choroba wywoływana przez bakterie z rodzaju Salmonella, które są najczęściej zgłaszaną przyczyną zatruć pokarmowych. Bakterie te infekują przede wszystkim przewód pokarmowy, powodując zapalenie żołądka i jelit (gastroenteritis). Salmonelloza występuje na całym świecie i może dotyczyć zarówno ludzi, jak i zwierząt12.

Zakażenie bakteriami Salmonella następuje zwykle poprzez spożycie surowego lub niedogotowanego mięsa, drobiu, jaj lub produktów jajecznych, a także poprzez picie niepasteryzowanego mleka. Do zakażenia może również dojść przez kontakt z zakażonymi zwierzętami lub ich odchodami12.

Okres inkubacji

Okres inkubacji, czyli czas między ekspozycją na bakterie a wystąpieniem objawów, może wynosić od 6 godzin do 6 dni, najczęściej jednak objawy pojawiają się w ciągu 12-36 godzin od zakażenia123. U niektórych osób objawy mogą pojawić się już po kilku godzinach od spożycia dużej ilości bakterii, lub dopiero po 72 godzinach w przypadku przyjęcia mniejszej ilości skażonej żywności1.

Objawy infekcji salmonellowej

Większość osób z infekcją salmonellową rozwija biegunkę, gorączkę i bóle brzucha w ciągu 8-72 godzin po ekspozycji. Często osoby zarażone bakteriami Salmonella myślą, że mają grypę żołądkową1.

Najczęstsze objawy

Do najczęstszych objawów infekcji salmonellowej należą123:

  • Biegunka (czasami z krwią lub śluzem)
  • Skurcze i bóle brzucha
  • Gorączka (zwykle 38-39°C)
  • Nudności
  • Wymioty
  • Dreszcze
  • Ból głowy
  • Bóle mięśniowe

123

Biegunka jest zazwyczaj wodnista, ale może również zawierać krew. U większości osób występują niektóre lub wszystkie wymienione objawy, przy czym najczęstsze to biegunka i gorączka12.

Mechanizm powstawania objawów

Gdy bakterie Salmonella dostają się do organizmu w wystarczającej ilości, aby pokonać kwasy żołądkowe i układ odpornościowy, wnikają do jelita i niszczą komórki jego wyściółki. To utrudnia organizmowi wchłanianie wody, co prowadzi do skurczów żołądka. Woda opuszcza organizm w postaci biegunki1.

Zapalenie jelit zakłóca normalną absorpcję wody i składników odżywczych, powodując wydzielanie większej ilości płynów przez jelita, co skutkuje luźnymi, wodnistymi stolcami. Zwiększone skurcze mięśni mogą prowadzić do bólu brzucha i skurczów, które mogą być silne podczas infekcji Salmonella12.

Gdy układ odpornościowy rozpoznaje bakterie Salmonella jako obce najeźdźcze, uwalnia cząsteczki zwane cytokinami, które mogą wywołać gorączkę i wpływać na ośrodkowy układ nerwowy, przyczyniając się do bólów głowy12.

Przebieg choroby

Objawy infekcji salmonellowej zazwyczaj utrzymują się od kilku dni do tygodnia. Biegunka może trwać do 10 dni, ale powrót jelit do normalnego rytmu wypróżnień może zająć nawet kilka miesięcy12.

Typowa salmonelloza przebiega w następujący sposób123:

  • Objawy pojawiają się zwykle 6-72 godzin po zakażeniu
  • Gorączka utrzymuje się zazwyczaj przez około 48 godzin
  • Większość osób dochodzi do zdrowia bez specjalistycznego leczenia w ciągu 4-7 dni
  • Biegunka może utrzymywać się do 10 dni
  • Całkowity powrót do zdrowia może trwać do kilku tygodni

12

U niektórych osób infekcja Salmonella może mieć przebieg bezobjawowy, podczas gdy u innych może wywołać poważne objawy wymagające hospitalizacji12.

Ciężki przebieg i powikłania

Chociaż większość przypadków salmonellozy ma łagodny przebieg i ustępuje samoistnie, u niektórych osób mogą rozwinąć się poważne powikłania1.

Grupy ryzyka ciężkiego przebiegu

Do grup szczególnie narażonych na ciężki przebieg infekcji salmonellowej należą12:

  • Dzieci poniżej 5 roku życia
  • Osoby starsze (powyżej 65 roku życia)
  • Kobiety w ciąży
  • Osoby z osłabionym układem odpornościowym (np. chorzy na raka, HIV/AIDS)
  • Osoby z chorobami przewlekłymi

12

Najczęstsze powikłania

Do najczęstszych powikłań salmonellozy należą1:

  • Odwodnienie – utrata płynów w wyniku wymiotów lub biegunki może prowadzić do odwodnienia, które nieleczone może zagrażać życiu
  • Bakteriemia i sepsa – gdy Salmonella przedostaje się do krwiobiegu, może rozprzestrzenić się do innych części ciała i wywołać groźne infekcje
  • Zapalenie kości (osteomyelitis) – rzadkie zakażenie kości, częstsze u osób z niedokrwistością sierpowatokrwinkową
  • Reaktywne zapalenie stawów – odpowiedź układu odpornościowego powodująca zapalenie stawów, oczu i dróg moczowych po infekcji

123

U niektórych osób, zwłaszcza z obniżoną odpornością, bakterie Salmonella mogą także rozprzestrzenić się do moczu, krwi, kości, stawów, mózgu lub innych narządów wewnętrznych, powodując objawy związane z daną częścią ciała lub układem1.

Objawy odwodnienia

Częsta biegunka i wymioty mogą prowadzić do odwodnienia, które jest najczęstszym powikłaniem salmonellozy. Objawy odwodnienia obejmują12:

  • Zmniejszone wydalanie moczu
  • Suche usta i gardło
  • Mniejsza ilość łez
  • Zapadnięte oczy
  • Uczucie pragnienia
  • Zawroty głowy lub uczucie omdlewania przy wstawaniu
  • Ciemniejszy kolor moczu

12

Reakcje autoimmunologiczne

U niewielkiej liczby osób z infekcją Salmonella rozwija się ból stawów nazywany reaktywnym zapaleniem stawów (zespół Reitera). Stan ten może utrzymywać się przez miesiące lub lata i prowadzić do przewlekłego zapalenia stawów12.

Objawy reaktywnego zapalenia stawów obejmują1:

  • Zapalenie (obrzęk, zaczerwienienie, ból) stawów, szczególnie kolan, kostek, stóp i pięt
  • Zapalenie dróg moczowo-płciowych
  • Zapalenie oczu

12

Gorączka tyfoidalna

Niektóre szczepy bakterii Salmonella mogą powodować gorączkę tyfoidalną, która jest poważniejszą, ogólnoustrojową postacią salmonellozy i może zagrażać życiu, jeśli nie jest szybko leczona antybiotykami1.

Objawy gorączki tyfoidalnej różnią się od typowej salmonellozy i obejmują12:

  • Wysoką gorączkę, nawet do 40°C
  • Brak apetytu
  • Ból głowy
  • Bóle mięśniowe
  • Zaparcia (w przeciwieństwie do biegunki w zwykłej salmonellozie)
  • Letarg i osłabienie

12

Kiedy szukać pomocy medycznej

Większość przypadków salmonellozy ustępuje samoistnie, ale w niektórych sytuacjach konieczna jest pomoc medyczna. Należy skontaktować się z lekarzem, jeśli występują12:

  • Objawy, które nie ustępują po kilku dniach
  • Wysoka gorączka (powyżej 38,5°C)
  • Krew w stolcu
  • Częste wymioty, uniemożliwiające przyjmowanie płynów
  • Objawy odwodnienia (ciemny mocz, zmniejszone oddawanie moczu, suchość w ustach)
  • Nasilający się ból brzucha

12

Należy natychmiast udać się na oddział ratunkowy, jeśli występują następujące objawy1:

  • Krew w moczu lub stolcu
  • Biegunka utrzymująca się ponad trzy dni
  • Zawroty głowy
  • Ekstremalne pragnienie
  • Wysoka gorączka (powyżej 38,9°C)
  • Bardzo małe oddawanie moczu lub ciemny mocz
  • Bardzo suche usta, oczy i gardło
  • Wymioty (niemożność zatrzymania płynów)

12

Długoterminowe skutki infekcji salmonellowej

U większości osób salmonelloza ustępuje bez długotrwałych następstw. Jednak u niektórych pacjentów mogą wystąpić długoterminowe skutki zdrowotne1:

  • Zespół jelita drażliwego (IBS) – niektóre osoby po przebytej salmonellozie doświadczają przewlekłych problemów jelitowych, takich jak wzdęcia, biegunka i ból brzucha
  • Przewlekła biegunka – u niektórych osób utrzymuje się długotrwała biegunka po infekcji
  • Zespół przewlekłego zmęczenia – rzadkie powikłanie charakteryzujące się uporczywym i niewytłumaczalnym zmęczeniem, które nie ustępuje po odpoczynku
  • Powikłania neurologiczne – w bardzo rzadkich przypadkach może rozwinąć się zespół Guillaina-Barrégo, rzadkie zaburzenie autoimmunologiczne atakujące obwodowy układ nerwowy

12

Badania sugerują, że salmonelloza wiąże się z późniejszym rozwojem zespołu jelita drażliwego i zapalnych chorób jelit1.

Objawy infekcji salmonellowej Częstość występowania Czas trwania
Biegunka (czasami z krwią lub śluzem) Bardzo częste (90%) 4-10 dni
Skurcze i bóle brzucha Bardzo częste (>65%) 2-7 dni
Gorączka (38-39°C) Bardzo częste Zwykle do 48 godzin
Ból głowy Częste 2-7 dni
Nudności i wymioty Częste 1-3 dni
Bóle mięśniowe Częste 2-7 dni
Dreszcze Mniej częste 1-2 dni
Krew w stolcu Mniej częste Zmienny
Reaktywne zapalenie stawów Rzadkie (10-30%) Miesiące do lat

Przebieg infekcji salmonellowej

Infekcja salmonellowa (salmonelloza) zazwyczaj przebiega jako samoograniczająca się choroba z objawami żołądkowo-jelitowymi, takimi jak biegunka, bóle brzucha i gorączka. Objawy zwykle pojawiają się w ciągu 6-72 godzin po zakażeniu i ustępują samoistnie po 4-7 dniach. Biegunka może jednak utrzymywać się do 10 dni, a całkowity powrót do normalnego funkcjonowania jelit może zająć kilka miesięcy123.

Choć większość osób zdrowieje bez specjalistycznego leczenia, u niektórych pacjentów, szczególnie z grup ryzyka (dzieci, osoby starsze, z obniżoną odpornością), mogą wystąpić poważne powikłania, takie jak odwodnienie, bakteriemia czy reaktywne zapalenie stawów. W rzadkich przypadkach bakterie Salmonella mogą rozprzestrzenić się poza jelita, powodując infekcje innych narządów12.

Ważne jest picie dużej ilości płynów, aby zapobiec odwodnieniu, a w przypadku wystąpienia niepokojących objawów, takich jak wysoka gorączka, krwawa biegunka czy objawy odwodnienia, należy niezwłocznie skonsultować się z lekarzem12.

  • #1 Salmonella: Outbreaks, Causes, Symptoms & Treatment
    https://my.clevelandclinic.org/health/diseases/15697-salmonella
    Salmonella, or salmonellosis, is an infection with Salmonella bacteria that causes diarrhea, fever and stomach pains. Salmonella usually goes away on its own in a few days. You should drink plenty of fluids to prevent dehydration. Symptoms of salmonella include diarrhea, stomach pains or cramps, fever, nausea, vomiting and headache. Symptoms of salmonella appear anywhere from a few hours to a few days after eating contaminated food. When you get salmonella, it means enough bacteria have gotten past your stomach acid and immune system to make you sick. Salmonella bacteria invade and destroy the cells that line your intestines. This makes it hard for your body to absorb water, which can give you stomach cramps. The water leaves your body in the form of diarrhea. Symptoms of salmonella appear anywhere from a few hours to a few days after exposure to Salmonella bacteria. Symptoms of salmonella affect your stomach and intestines (GI tract) and include: Diarrhea (sometimes bloody). Fever. Stomach pains or cramps. Nausea and vomiting. Headache. You may have some or all these symptoms. No, you dont always throw up when you have Salmonella poisoning. The most common symptoms are diarrhea and fever, though you do sometimes throw up. When you have a salmonella, your poop is usually runny and you may have to go a lot. It may have blood in it. Call or visit your healthcare provider if you have blood in your poop. Salmonella poisoning is caused by the bacteria Salmonella. When more Salmonella bacteria get into your body than it can destroy, you get an infection that causes fever, diarrhea and other stomach (gastrointestinal) issues. Salmonella is usually self-limiting, meaning it goes away without treatment after a few days of symptoms. Most of the time you can manage at home until you feel better. Symptoms of salmonella usually last between four and seven days. Talk to your healthcare provider if your symptoms arent improving after three days. Salmonella complications may include: Dehydration. Loss of fluids from vomiting or diarrhea can lead to dehydration. If untreated, it can become life-threatening. Bacteremia and sepsis. When salmonella enters your bloodstream, it can travel to other parts of your body and cause dangerous infections. Osteomyelitis. A rare bone infection, more common in people with sickle cell disease. Reactive arthritis. An immune system response that causes inflammation in your joints, eyes, and urinary tract after infection. You should contact your healthcare provider if your symptoms dont get better after a few days. You should go to the ER if you have signs of serious illness or dehydration, including: High fever. Blood in your poop. Throwing up frequently, not being able to keep food or liquids down. Dark-colored pee or less pee (urine) than usual. Dry mouth or throat. Feeling dizzy when you stand.

    https://www.mayoclinic.org/diseases-conditions/salmonella/symptoms-causes/syc-20355329
    Salmonella infection is usually caused by eating raw or undercooked meat, poultry, and eggs or egg products or by drinking unpasteurized milk. The incubation period the time between exposure and illness can be 6 hours to 6 days. Often, people who have salmonella infection think they have the stomach flu. […] Most people develop diarrhea, fever and stomach (abdominal) cramps within 8 to 72 hours after exposure. […] Possible signs and symptoms of salmonella infection include: Diarrhea, Stomach (abdominal) cramps, Fever, Nausea, Vomiting, Chills, Headache, Blood in the stool. […] Signs and symptoms of salmonella infection generally last a few days to a week. Diarrhea may last up to 10 days, but it may take several months before bowels return to usual stool habits.

    https://www.pasteur.fr/en/medical-center/disease-sheets/salmonella-infection-salmonellosis
    The first symptoms of Salmonella infection occur on average 12 to 36 hours after eating a contaminated product. This may vary depending on the quantity of bacteria absorbed. Symptoms may begin just 6 hours after ingesting a large quantity of bacteria, or up to 72 hours after eating a small amount of contaminated food. […] Some people are more likely to develop severe symptoms: elderly people, young children, pregnant women and people under heavy medication may develop a more severe form of illness. […] It is thought that there are around 100,000 to 200,000 cases of Salmonella infection in France each year, leading to 4,000 hospitalizations. Estimates suggest that between 50 and 100 deaths are caused by Salmonella infection each year.

    Persistent diarrhea, vomiting, and severe stomach cramps can cause significant discomfort. […] This is especially true for salmonella poisoning, where you may be experiencing these symptoms for up to two weeks. […] The symptoms of salmonella infection last a few days to two weeks. However, it may take several months for your bowels to return to normal. […] Common signs and symptoms of salmonella poisoning include: […] The inflammation disrupts the guts normal absorption of water and nutrients, making the intestines secrete more fluids. […] This causes excess fluid in the intestines, resulting in loose, watery stools. […] Increased muscle contractions can lead to abdominal pain and cramping, which can be severe with salmonella infection. […] When the immune system recognizes the salmonella bacteria as foreign invaders, it releases molecules called cytokines that can induce a fever.

    Salmonellosis ranges clinically from the common Salmonella gastroenteritis (diarrhea, abdominal cramps, and fever) to enteric fevers (including typhoid fever) which are life-threatening febrile systemic illness requiring prompt antibiotic therapy. […] The most common form of salmonellosis is a self-limited, uncomplicated gastroenteritis. […] The incubation period for Salmonella gastroenteritis (food poisoning) depends on the dose of bacteria. Symptoms usually begin 6 to 48 hours after ingestion of contaminated food or water and usually take the form of nausea, vomiting, diarrhea, and abdominal pain. Myalgia and headache are common; however, the cardinal manifestation is diarrhea. Fever (38C to 39C) and chills are also common. At least two-thirds of patients complain of abdominal cramps. The duration of fever and diarrhea varies, but is usually 2 to 7 days.

    Enteric fevers are severe systemic forms of salmonellosis. […] The symptoms of enteric fevers are nonspecific and include fever, anorexia, headache, myalgias, and constipation. Enteric fevers are severe infections and may be fatal if antibiotics are not promptly administered. […] After invading the intestine, most salmonellae induce an acute inflammatory response, which can cause ulceration. […] Because of the intestinal inflammatory reaction, symptoms of inflammation such as fever, chills, abdominal pain, leukocytosis, and diarrhea are common. The stools may contain polymorphonuclear leukocytes, blood, and mucus. […] The diarrhea is due to secretion of fluid and electrolytes by the small and large intestines. […] Invasion of the intestinal mucosa is followed by activation of mucosal adenylate cyclase; the resultant increase in cyclic AMP induces secretion.

    Salmonellosis is a common bacterial infection caused by the Salmonella species, one of the leading causes of foodborne illnesses in the world. […] Once ingested, Salmonella bacteria infect the gastrointestinal tract, leading to a range of symptoms, including diarrhea, abdominal pain, fever, and vomiting. In most cases, symptoms subside within 4-7 days without the need for medical intervention. However, there are instances where the infection can cause more severe complications, some of which can result in long-term health issues. […] The primary symptoms of salmonellosis are gastrointestinal in nature. These include: Diarrhea: This is typically the most common symptom, and it can vary from mild to severe. In some cases, diarrhea can be watery or even bloody. Abdominal Pain: Cramping and discomfort are common, often occurring in the lower abdomen. Fever: A mild to moderate fever is often present. Nausea and Vomiting: These symptoms may also accompany the infection, though they are less common than diarrhea. Headache and Muscle Aches: General discomfort and tiredness may also be experienced.

These complications can last for months or even years and can significantly affect a persons quality of life. […] Some individuals who have recovered from salmonellosis experience ongoing gastrointestinal issues, such as bloating, diarrhea, and abdominal pain, which are characteristic of irritable bowel syndrome (IBS). This condition is sometimes referred to as post-infectious IBS and can be triggered by a bacterial infection like salmonellosis.
  • #1 Salmonellosis – Wikipedia
    https://en.wikipedia.org/wiki/Salmonellosis
    Typhoid fever occurs when Salmonella bacteria enter the lymphatic system and cause a systemic form of salmonellosis. Endotoxins first act on the vascular and nervous apparatus, resulting in increased permeability and decreased tone of the vessels, upset thermal regulation, vomiting, and diarrhea. In severe forms of the disease, enough liquid and electrolytes are lost to upset the fluid balance, cause an electrolyte imbalance, decrease the circulating blood volume and arterial pressure, and cause hypovolemic shock. […] Salmonellosis is associated with later irritable bowel syndrome and inflammatory bowel disease. A small number of people afflicted with salmonellosis experience reactive arthritis, which can last months or years and can lead to chronic arthritis.
