Eosinophilic gastroenteritis is an eosinophilic infiltrate in the stomach, small intestine, colon, and rectum causing clinical symptoms. Knowing the process of formation and signs of the disease will help improve the effectiveness of treatment.

The diagnosis of eosinophilic gastroenteritis is confirmed by biopsy or collection of eosinophilic ascites in the absence of other pathogens, including intestinal parasites. Eosinophilic esophagitis should also be differentially diagnosed and discussed.

Hemorrhagic ulcerative colitis (CRC) is a chronic inflammatory bowel disease affecting the colon with an unclear pathogenesis. Research on this pathology has mainly developed in the last 100 years, however, in the literature, the record of a pathology characterized by diarrhea and having similar properties to CAP has been described since long.

Ulcerative colitis (ulcerative colitis) is a chronic inflammatory condition of unknown cause and with a relapsing clinical course. About half of the patients had a mild episode and were easily managed with aminosalicylate, while the other half required at least one course of oral or intravenous corticosteroids.

Leukopenia can be due to inherited autoimmune diseases, or due to immune system deficiency, certain diseases, or the use of certain medications that cause side effects.

Blood consists of blood cells and plasma, plasma is the liquid part of blood. This is the fluid that carries blood cells, the tiny particles that float in the plasma.

White blood cells travel through the bloodstream and destroy viruses, bacteria, and other foreign substances in the human body that can cause disease or infection. White blood cells form a defense barrier to protect the body from foreign substances.

White blood cells are one of the cellular components of the blood that have an immune function to protect the body against the invasion of agents such as bacteria, viruses, parasites, etc. Besides, there are also many types of white blood cells such as neutrophils, lymphocytes, monocytes, eosinophils, basophils that respond to different types of bacterial agents with different changes.

Eosinophilic esophagitis is an emerging disease and was once considered a rare condition but is now becoming more common, due to abnormal infiltration of eosinophils into the esophageal mucosa, affecting the esophageal structural function - can progress to reduce the diameter and narrow the esophagus. Careful evaluation of patients with dysphagia is needed to detect the disease and start treatment early for the patient.

Eosinophilic esophagitis (EOS) is an inflammatory condition in which the esophageal wall is infiltrated with large numbers of eosinophils, a condition first recognized in 1978.

Hemophagocytic lymphohistiocytosis is a rare but dangerous disease. It mainly occurs in children and sometimes also appears in adults, with the characteristic manifestation being immune dysfunction in the body.
