| Popis: | The paper presents literature data, outlining topical issues of the cardiovascular pathology at mucopolysaccharidosis. It is damage to the heart and blood vessels, one of the cardinal signs of this pathology, that is often fatal. Cardiac pathology is recorded in all types of mucopolysaccharidosis, but it is most significant for patients with three clinical variants of Hurler syndrome, Hunter, and Maroteaux–Lamy syndromes. Typical signs of damage to the cardiovascular system in mucopolysaccharidosis are thickening of the valves with the development of their dysfunction (while the severity of damage to the left‑sided valves is more pronounced), myocardial hypertrophy, conduction disturbance, coronary artery disease, arterial hypertension. Many researchers emphasize the difficulties of clinical and functional examination of the cardiovascular system in patients with mucopolysaccharidosis, which is due to the presence of physical and intellectual limitations in patients, and a gradual symptoms aggravation. For the treatment of cardiovascular pathology at mucopolysaccharidosis, medical and surgical methods are used, including enzyme replacement therapy and stem cell transplantation. Gene therapy is considered one of the priority areas in the treatment of mucopolysaccharidosis. Significant progress in this aspect has been achieved with the use of viral vectors under experimental conditions in mice with mucopolysaccharidosis type VII. The basis of mucopolysaccharidosis prevention is medical and genetic counseling of families with subsequent prenatal diagnosis using molecular genetic methods (eg, DNA diagnosis). Thus, early diagnosis and timely pathogenetic treatment of mucopolysaccharidosis will help to prevent disability and adequate integration into society, and effective medical and genetic counseling of families will significantly reduce the incidence of new cases of these severe inherited diseases. |
