[Dermatophagoides pteronyssinus mites in the Republic of Tajikistan]. / Kleshchi Dermatophagoides pteronyssinus v Respublike Tadzhikistana.

Studies were first carried out in the Republic of Tadjikistan to identify Dermatophagoides mites [correction of ticks]. They showed that they were present in the domestic dust from the bedding of patients with bronchial asthma. Their sensitivity to the allergen of domestic dust was determined.

[The etiological structure of acute viral hepatitis in Tadzhikistan in a period of decreased morbidity]. / Etiologicheskaia struktura ostrykh virusnykh gepatitov v Tadzhikistane v period snizheniia zabolevaemosti.

In the period of reduced incidence of viral hepatitis in Tajikistan, January-December, 1990, 1562 patients with acute viral hepatitis (AVH) were examined in the first days of the jaundice phase (928 children under 14 years and 634 adults) in Dushanbe. Markers of hepatitis A, B, and D (HBsAg, anti-HA IgM, anti-HBc IgM, anti-delta IgM) were determined by enzyme immunoassay. Hepatitis A occurred in 25.8% of the patients with AVH, mostly children of 1-6 years, HB in 22.8%, HD co- and superinfection) in 9.2%. In 42.1% of the patients who had no HA, HB, or HD markers in the blood, non-A, non-B hepatitis (mostly hepatitis E) was diagnosed, mainly in the age groups of 30-39 years (70.7%) and 15-29 years (59.2%). Thus, in Tajikistan hepatitis E occurs not only during outbreaks of this infection but also sporadically.

[Seroepidemiologic study of immunity to rubella among the population of Tadzhikistan]. / Seroépidemiologicheskoe izuchenie immuniteta k krasnukhe u naseleniia Tadzhikistana.

The first serological survey of the human population of Tajikistan was carried out with the purpose of detection of antibody inhibiting hemagglutination of rubella virus. As a result, in over 2500 persons high intensity of formation of the herd immunity was established. A greater portion of the population (66%) acquired antibody in preschol age. The formation of the immune portion completed by 10--14 years of age. Among women of the child-bearing ages about 8--15% had no antibody to rubella virus. This value in combination with intensive spread of rubella among children indicates that in this republic the epidermiological situation with rubella appears to be unfavourable for adult women.

[Etiology of pneumonias in young children according to data from comprehensive immunomicrobiological, virological and parasitological studies]. / Etiologiia pnevmonii u detei rannego vozrasta po dannym kompleksnogo immunomikrobiologicheskogo, virusologicheskogo i parazitologicheskogo issledovaniia.

Investigations carried out demonstrated acute pneumonia in young children to be characterized by the presence in the sputum from the deep respiratory tract of polymicrobial flora, in some of viral-microbial-fungus flora, and also of pneumocysts. Immunobiological and virological study demonstrated the etiological role of 7 virus species and 2 bacteria species in 70.8% of cases; pneumonia of viral etiology constituted 24.1 +/- 3.0%, of bacterial -- 24.6 +/- 3.0%, and of viral-bacterial -- 22.1 +/- 2.0%. In order to unify the approaches and methods of study of pneumonia etiology in young children complex immunomicrobiological, virological, and parasitological method of study is suggested.
