CYP2C19*2 gene variant (G681A, rs4244285) as a prognostic marker for the clinical course of multiple myeloma.

Background: Multiple myeloma (MM) is the most common type of paraproteinemic hemoblastosis, which is characterized by an aggressive course, high mortality and a large number of complications. The G681A variant (*2, rs4244285) of the CYP2C19 gene leads to the formation of an inactive enzyme and, as a consequence, may affect the development and course of MM. The aim of this research was to analyze the effect of the G681A variant of the CYP2C19 gene on the risk of the development of MM and its course.

A Ukrainian multicenter prospective study of the value of PET/ CT prognostic role in primary patients with Hodgkins lymphoma in a real-life cohort.

Introduction: In recent years, the positron emission tomography combined with computed tomography (PET/CT) has changed and the treatment approaches in Hodgkins lymphoma (HL) patients have entirely improved. The main idea in several studies is the use of PET/CT and the International Prognostic Score (IPS) protocols in identification of patients within a high-risk group and potential early relapse/refractory disease.

Materials And Methods: This study was based on PET/CT evaluation and treatment strategies of patients from eight Centers of Hematology in Ukraine.

DEVELOPMENT OF GANGLIONOPATHY AND TABETIC VISCERAL CRISES ON THE BACKGROUND OF POLYRADICULONEUROPATHY ASSOCIATED WITH MONOCLONAL GAMMOPATHY (CASE REPORT).

The article presents an analysis of the clinical occurrence of development of chronic polyradiculoneuropathy associated with monoclonal IgG/k (kappa) gammopathy of the undetermined significance. The peculiarity of this occurrence is the uniqueness of the development of the symptoms which are characteristic of tabes dorsalis in this pathology with episodic severe visceral crises and also with ganglionopathy. The example describes the clinical polymorphism of the course of visceral crises, the problems of their diagnosis and as a consequence of inadequate treatment with the development of severe social maladaptation.

[Pneumococcus pathogenicity factors and their protective properties].

Owing to rapid development of molecular-biological and genetic methods of research in infectology as well as use of adequate models (tissue colonization of human respiratory epithelium, mice models of colonization, sepsis and meningitis), a significant progress in the field of pneumococcus pathogenicity factors has been made in the last decades. Aside from the well-known pathogenicity factor--capsule polysaccharide, to date several dozens of surface proteins providing adhesion, colonization and invasion have been detected in pneumococcus. Pneumolysin is a toxic factor and at the same time brain invasion factor.

[Experience of using thalidomide in the treatment of patients with multiple myeloma].

The results of treatment of patients with multiple myeloma with thalidomide and complications of this treatment are presented. Monotherapy with thalidomide and its combinations with corticosteroids and cytostatics is an effective as first line treatment and as a treatment of patients with refractory disease. The most common side effect is toxic neuropathy.
