Materials and methods. HLA genotyping was accomplished in 51 DM1 patients and 51 volunteers randomly selected from the indigenous populationof Yakutia (Yakuts in three successive generations). Another 205 DM1 patients and 300 healthy subjects comprised random samples of patients andcontrols respectively from residents of Moscow and Moscow region. Results. HLA DRB1*17(03) allele proved to be the strongest one predisposing to DM1 in the Yakutian population (relative risk, RR=8,47) andDQB1*0304 in the Moscow population (RR=8,94). The presence of DRB1*04, DRB1*17(03), DQA1*0301, DQB1*0201, and DQB1*0302 accountedfor RR >2 in both populations. Only two alleles, DRB1*04 and DRB17(03), in the Yakutian population and five of the six (DRB1*04,DRB1*17(03), DQA1*(0301), DQB1*0302, and DQB1*0304) in the Moscow one were closely associated with DM1 (RR >4). DRB1*09, DRB1*11,DQB1*13, DQB1*0602/8 in Yakutian and DRB1*11, DRB1*13, DQA1*0103, DQB1*0301, DQB1*0602/8 in Moscow populations had the highestprotective potential (RR

Systemic scleroderma is an autoimmune disease of the connective tissue of unknown etiology. It is characterized by skin induration, lesions in the musculoskeletal system and the internal organs, and the Raynaud syndrome. An important component in pathogenesis of systemic scleroderma is disturbance of microcirculation involving endothelial proliferation and destruction, wall thickening and narrowing of the microvessel lumen, vasospasm, hemocyte aggregation, stasis, deformation and reduction of the capillary network (obliterating microangiopathy). Two main forms of the disease are distinguished: the diffuse and localized ones. The systemic nature of the diffuse form of systemic scleroderma is most obvious in the skin, but the digestive tract, respiratory organs, kidneys and the cardiovascular, endocrine, musculoskeletal and genitourinary systems are also affected. The incidence rate of systemic scleroderma is 6.3—12 cases per million population. Single case reports on scleroderma combined with other autoimmune diseases, including type 1 diabetes mellitus, in children and adolescents are available in literature. A rare case of a combination of two autoimmune diseases, type 1 diabetes mellitus and systemic scleroderma, in a 13-year-old girl is reported in this paper.

HLA-гаплотипы, аутоантитела к β-клеткам: роль в прогнозировании сахарного диабета 1 типа (результаты 11-летнего наблюдения) Титович Е.В., Кураева Т.Л., Прокофьев С.А., Петеркова В.А., Дедов И.И. (26,1%, 14,1%, 11,1% соответственно, p>0,05; 8,7%, 2,4%, 0% соответственно; p<0,05). Один вид антител также чаще встречался в группе высокого риска по сравнению с другими двумя (52,1%, 27,6%, 26,2% соответственно). ФГУ При этом GAD достоверно чаще определялись в группе с генотипом DQ2/DQ8 по сравнению с группой среднего и низкого генетического риска (65%, 37,9%, 18% соответственно; p<0,05). Антитела к инсулину, соответственно, выявлялись в 19%, 12,9% и 3,7% случаях (p I-III <0,05). Достоверных различий по распро-страненности ICA в группах не получено. За 11-летний период наблюдения манифестация СД1 произошла у 11 человек (6,4%), что соответ-ствует полученному ранее при популяционных исследованиях среднему риску развития заболевания у сибсов. Из группы высокого риска заболели
