LECTURE No. 12. Malabsorption syndrome in children. Clinic, diagnosis, treatment

Enteropathy is a pathological condition that leads to a deficiency or impaired function of certain intestinal enzymes, due to the absence, deficiency or violation of the structure of certain intestinal enzymes that provide digestive processes.

Carbohydrate absorption: Food carbohydrates are composed of disaccharides:

1) sucrose (regular sugar = fructose + glucose), lactose (milk sugar = galactose + glucose);

2) monosaccharides: glucose and fructose;

3) plant starches (polysaccharide consisting of glucose molecules).

Enterocyte is not able to transport carbohydrates more than monosaccharide. Therefore, carbohydrates must be broken down before absorption. Malabsorption syndrome - a syndrome of impaired intestinal absorption, can result in malabsorption syndrome: a lack of pancreatic enzymes - a violation of the cavity phase of digestion; cholestasis, intestinal dysbiosis - a violation of the metabolism of bile acids, lipid transport to a violation of the biliary phase of digestion; deficiency of cavity enzymes (disaccharidases, peptidases, etc.
item) leads to a violation of membrane digestion; atrophy of the mucous membrane of the small intestine - to a violation of absorption, i.e., the cellulary phase of digestion, while membrane digestion also suffers; pathology of intestinal lymph flow, mesenteric circulation to - deterioration of further transport of absorbed substances - the outflow phase suffers; accelerated passage of food through the intestines - to the violation of all types of digestion.

    Rheumatism is a systemic inflammatory disease of the connective tissue with characteristic heart damage. Etiology, pathogenesis. The main etiological factor in acute forms of the disease is group A b-hemolytic streptococcus. In patients with protracted and continuously recurring forms of rheumatic heart disease, it is often not possible to establish a connection between the disease and streptococcus.

  8. LECTURE No. 1. Immunodeficiency conditions in children. Clinic, diagnosis, treatment
    Immunity is a way of providing and maintaining antigenic homeostasis. Immunodeficiencies - a decrease in the functional activity of the main components of the immune system, leading to a violation of the antigenic homeostasis of the body and, first of all, to a decrease in the body's ability to defend itself against microbes, which is manifested in increased infectious morbidity. Classification of immunodeficiency conditions: 1) primary

Laboratory methods: (AlAT, AsAT, ALP, proteinogram, thymol, prothrombin index, bilirubin and urine urobiligen) - an assumption of a diagnosis. Hepatic parenchymal clearance of blood with technetium is the only or early sign of the disease (hepatitis, cirrhosis, amyloidosis). Ultrasound and liver scintigraphy with technetium (confirmation

    Three phases of microbial colonization of the gastrointestinal tract in a child: 1) the first is aseptic, lasting from 10 to 20 hours; 2) the second - the initial colonization by microorganisms, the duration from 2 to 4 days, depending on external environmental factors, the nature of nutrition and time of application to the breast; 3) the third - stabilization of microflora (up to 1 month). Intestinal microflora is complex, dynamically
