[Iron deficiency anemia in a patient with hereditary hemorrhagic telangiectasia. Case report].

Rendu-Osler-Weber disease or hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant disease. It is characterized by vascular dysplasia with the formation of telangiectasias on the skin, mucous membranes of the respiratory and digestive tracts, arteriovenous malformations (AVMs) in the internal organs, which is manifested by bleeding. Diagnosis is based on Curacao criteria: recurrent and spontaneous nosebleeds, multiple telangiectases on the characteristic localizations, AVMs in one or more of the internal organs, a family history of HHT (i.e. first-degree relative who meets these same criteria for definite HHT). Therapy is aimed at preventing and stopping gastrointestinal, nosebleeds, correction of iron deficiency anemia. A promising method of therapy is the use of angiogenesis inhibitors, in particular bevacizumab. The article presents a description of a clinical case of HHT in a 49-year-old woman with telangiectisia on the mucous membrane of the tongue, gastrointestinal tract and liver AVMs.

[Gaucher disease: achievements and prospects].

Gaucher disease (GD) is the most common lysosomal storage disorder, resulting from a deficiency in the activity of a lysosomal enzyme glucocerebrosidase, which is involved in the catabolism of sphingolipids. The phenomenal progress in understanding the pathogenesis and development of specific therapy of this disease over the past 60 years dramatically changed the clinical phenotype of GD, turning a severe progressive disorder into an asymptomatic metabolic defect. The evolution of the understanding of GD associated with fundamental discoveries in the field of cell biology, biochemistry and genetics may be of interest to a wide audience as a model of the effective work of the scientific community in the treatment of rare metabolic pathology.

Differential radiological diagnosis of tuberculous sacroiliitis and bone involvement in Gaucher disease: a clinical case.

Differential diagnosis of bone involvement in patients with Gaucher disease can be challenging. Other diseases with similar radiological signs should be ruled out. Here we present a clinical case of tuberculous sacroiliitis in the patient with type I Gaucher disease. Advanced radiological methods of examination are described. Our case report proves the necessity of an individual approach to the management of such cohort of patients. Keywords: Gaucher disease, tuberculosis of bones and joints, differential diagnosis, comprehensive treatment.

[Enzyme replacement therapy in adult patients with type I Gaucher disease].

Enzyme replacement therapy (ERT) is the standard for the treatment of Gaucher disease (GD). A lifelong intravenous administration of a recombinant analogue of human glucocerebrosidase compensates for the functional deficiency of its own enzyme. The use of ERT has changed the clinical phenotype of GD, a severe progressive disease has been turned into the status of an asymptomatic metabolic defect. At the same time, a reduced dosing ERT regimen applied in Gaucher patients who had achieved therapeutic goals has not yet been developed.

Constrictive pericarditis in a patient with inherited factor VII deficiency.

Constrictive pericarditis (CP) is the final stage of a chronic inflammatory process characterized by fibrous thickening and calcification of the pericardium that impairs diastolic filling, reduces cardiac output, and ultimately leads to heart failure. We present a clinical case of CP in a patient with rare inherited bleeding disorder - factor VII deficiency. Heart failure due to CP was suspected based on clinical symptoms, results of ultrasonic and radiological investigations. The diagnosis was verified by the results of cardiac magnetic resonance imaging. Pericardectomy was performed resulting in significant improvement in the patient's condition.

[Progressive pulmonary hypertension in a patient with type 1 Gaucher disease]. / Progressiruiushchaia legochnaia gipertenziia u patsienta s bolezn'iu Goshe I tipa.

Gaucher disease is the most common form of hereditary enzymopathies combined into a group of lysosomal storage diseases. The basis for the disease is a hereditary deficiency of the activity of acid ß-glucosidase, a lysosomal enzyme involved in the catabolism of lipids, which results in the accumulation of nonutilized cellular metabolism products in the macrophage lysosomes. The main clinical manifestations of type 1 Gaucher disease are cytopenia, hepatomegaly, and splenomegaly, and bone lesion. One of the atypical clinical manifestations of Gaucher disease is damage to the lungs with the development of pulmonary hypertension, which is usually considered within the underlying disease - the development of pneumosclerosis due to macrophage dysfunction. The paper describes a case of progressive pulmonary hypertension in a patient with type 1 Gaucher disease.
