Lots of feces

Introduction Intestinal amebiasis is severe, sudden onset, high fever, severe intestinal colic for a long time, followed by discharge of mucus blood or bloody stool, 10 times a day, with urgency and weight, more feces, accompanied Have vomiting, loss of water, or even collapse or intestinal bleeding, intestinal perforation or peritonitis. Amoebic infections are caused by Rhizopoda, Amoebina, Ent-amoebidae, Entamoeba, and various Amoeba. Caused, the clinical habit is referred to as amoeba. Among them, the intestinal amoeba, although many species, mostly parasitic in the human body as a cohabiting organism without pathogenic ability, only the parasitic tissue of the amoeba parasitic in the human body, under certain conditions, can cause disease, is considered It is a pathogenic amoeba.

Cause

(1) Source of infection

The main source of infection is those who continue to receive cysts in the feces, including chronic patients, recovery periods, and asymptomatic carriers. Because the capsule is resistant to the external environment, it can survive for 5 weeks in the feces, such as contaminated water and food, which can spread the disease. Patients in the acute phase often discharge a large number of trophozoites, but die rapidly in the external environment, so patients in the acute phase are not included in the main source of infection. Human is the main host and storage host for the tissue amoeba. Although mites, pigs, dogs, rats, etc. can naturally infect E. histolytica, the source of infection is of little significance.

(2) Route of infection

It is generally believed that amoeba cysts contaminate things and water, and oral infection is the main route of transmission. Water pollution causes endemic epidemics. Raw and contaminated fruits and vegetables can also cause disease. Fly and cockroaches can also play a role in transmission. Male homosexuals can be infected by oral-pussy contact.

(3) Susceptibility to the population

The population is generally susceptible. There is no difference in gender, and there are relatively few chances of babies and children. Malnutrition, low immunity and treatment with immunosuppressive agents have many chances of developing diseases. Although the antibody titer is high after infection in the population, it has no protective effect, so repeated infection is more common.

(4) Popular features

It is distributed all over the world and is highly prevalent in tropical and subtropical areas. The infection rate is related to health conditions and living habits. In a few indeveloped countries, the infection rate is estimated to be 50%. In the world, the average infection rate is about 10%. In recent years, cases of acute amoebic dysentery and liver abscess in China are rare, and only some areas are still distributed.

1, chronic diarrhea or intestinal dysfunction, suspected and intestinal amebiasis.

2, typical dysentery-like mucus bloody stools, mild symptoms of poisoning, recurrent tendency, fecal microscopic examination to find the immersed red blood cells in the tissue of the amoeba trophozoite, can be diagnosed as intestinal amebiasis.

3, there are typical symptoms, but no pathogens are found in the feces, you can use serological tests or carefully observe the application of special effects, narrow-spectrum amoeba drugs, such as effective clinical diagnosis. The prognosis is generally good. Uncomplicated patients and patients who achieve effective pathogen treatment have a good prognosis. Patients with bowel disease or fulminant have a poor prognosis.

Differential diagnosis

Differential diagnosis of feces:

1, light

The clinical symptoms were not obvious, abdominal pain, diarrhea occurred intermittently, and there were cysts in the feces. Often a mixed infection of pathogenic and non-pathogenic insects. Intestinal lesions are mild, and antibodies are formed. When the body's resistance is reduced, symptoms of dysentery or liver abscess may occur.

2, ordinary type

Including acute and chronic manifestations, systemic symptoms are mild, no fever, slow onset of intermittent diarrhea, also known as amoebic dysentery. The typical acute manifestation is that the mucus blood is jam-like, more than 10 times a day, the amount of stool is medium, the feces are more, there is a foul smell, and the trophozoite can be found by a microscopic examination. The basic manifestation of this type is colonic rectal fever, the severity of the symptoms is related to the extent of the lesion. If the lesion is confined to the cecum, ascending colon, and the mucosal ulcer is lighter, the stool will increase this time. Even bloody stools will show typical relief. Those who are not treated or treated are prone to relapse or become chronic. Chronic symptoms can alternate for several months or years, and repeated episodes can lead to anemia, fatigue, bloating, changes in bowel movements or intestinal dysfunction, and physical examination touches colon thickening and tenderness. Stool examinations can have trophozoites and/or cysts.

3, heavy

Sudden onset, high fever, severe long-term colic colic, and then discharge mucus blood or bloody stool, 10 times a day, with urgency, heavy stools, accompanied by vomiting, water loss, and even Collapse or intestinal bleeding, intestinal perforation or peritonitis. This type is rare in people with severe infections, malnutrition, pregnant women or hormone therapy.
