Cystic fibrosis (cystic fibrosis of the pancreas) is characterized by a systemic lesion of the exocrine glands by increasing the viscosity of their secretion, which, as applied to the bronchopulmonary system, causes a sharp violation of the cleansing function of the bronchi and bronchial permeability. Frequent monogenic disease due to mutation of the cystic fibrosis gene, characterized by lesions of the exocrine glands, vital organs and systems, and usually having a severe course and prognosis. In most countries of Europe and North America, CF rates range from 1: 2000 to 1: 4000 newborns. In Russia, 1: 12 000 newborns. It is inherited in an autosomal recessive manner, i.e., both parents must be carriers of the mutant gene. The probability of birth of a patient with CF in such a family is 25%, 2-5% of the population are carriers of the MV gene. The CF gene was isolated in 1989 and is located in the middle of the long arm of the 7th chromosome. To date, more than 1000 gene mutations have been isolated. The most frequent mutation is del F 508 (53%). Mutations of the CF gene in the homozygous state lead to disruption of protein synthesis, which forms the chlorine channel in the membranes of epithelial cells, through which passive transport of chlorine ions occurs. This protein is called the cystic fibrosis transmembrane conductivity regulator (MBTP). Pathogenesis. The pathogenesis is that the secret of the exocrine glands, due to dysfunction of the chlorine canal, becomes particularly viscous, which explains most of the pathological processes underlying the pathogenesis of the disease. Clinic. In the bronchopulmonary system, a viscous secret, accumulating in the lumen of the bronchi, leads to complete obstruction of small bronchioles. As a result of infection with pathogenic microflora purulent inflammation develops. The most frequent pathogens are: staphylococcus and pyocyanic stick. The bronchial wall is destroyed. Formed bronchiectasis, pulmonary heart. In patients with cystic fibrosis, the chlorine channel on the apical part of the cell membrane “does not work”, resulting in impaired chlorine release from the cell, which contributes to an increased departure of sodium ions from the lumen into the cell, followed by the water component of the intercellular space. The result is a thickening of secretions of external secretion glands (bronchopulmonary system, pancreas, salivary glands, sex glands). The presence in the family of diseases of the lungs and intestines, stillbirths, spontaneous abortions. From birth - dry, hacking cough. Early onset of continuous relapsing bronchopulmonary inflammation. Exhaustion and physical development. Respiratory failure. "Drumsticks". Kilevidny bulging of the sternum. FER - persistent obstructive and restrictive disorders. Often seeding Pseudomonas. Pulmonary heart. Almost all patients excretory pancreatic insufficiency.

Pathophysiology Cystic fibrosis is a hereditary disease of the exocrine glands, which mainly affects the lungs and the gastrointestinal tract. The accumulation of an extremely thick and viscous secretion in the tracheobronchial tree in combination with a reduced activity of the ciliary epithelium causes pneumonia, wheezing and bronchiectasis. In the study of respiratory function
- Malformations of the pancreas
Hypoplasia (ICD-10: Q45.0), ectopia (ICD-10: Q45.8) of the pancreas are accompanied by impaired exocrine function in combination with or without endocrine disorders. Early adherence to symptoms of a fat-soluble vitamin deficiency is characteristic. Diagnosis is based on abdominal ultrasound, determining the activity of elastase in the feces, data from a coprological study and a stool lipidogram.

Among the autosomal recessive diseases, cystic fibrosis (cystofibrosis of the pancreas) is the most common. Its frequency among newborns in the European population is 1: 2500. The disease is caused by a generalized lesion of the exocrine glands. The cystic fibrosis gene is located on the 7th chromosome. This gene controls protein synthesis, called the transmembrane regulator.
- HEREDITARY DISEASES WITH UNBINDED PRIMARY BIOCHEMICAL DEFECT
The overwhelming majority of monogenic hereditary diseases are diseases with an unknown primary biochemical defect. For many of them, certain metabolic disturbances in the body are established at the level of pathological metabolites; however, the place of detectable biochemical deviations in the pathogenesis of the disease or the sequence of deviations remains unclear. In other cases there is no information about
