Цель работы. Исследование механизмов, лежащих в основе развития неонатальной аллоиммунной тромбоцитопении (НАИТ) в России. Материалы и методы. Генетические полиморфизмы аллоантигенов тромбоцитов человека (Human Platelet Antigens, HPA) -1, -2, -3, -4, -5 и -15 определяли в 27 семьях, в которых родились дети с НАИТ. Для диагностики НАИТ использовали следующие критерии: 1) наличие тромбоцитопении у новорожденного; 2) отсутствие тромбоцитопении и повышенного количества тромбоцит-ассоциированных IgG у матери, 3) наличие в плазме /сыворотке матери антител, реагирующих с тромбоцитами отца. Генотипирование выявило наличие несовместимости по НРА аллоантигенам у 23 из 27 обследованных семей. В 16 (70%) из 23 семей обнаружены HPA-1 конфликты. В 8 случаях матери оказались гомозиготными носителями редкого НРА-1b аллеля, а в других 8 – НРА-1а аллеля, что явилось причиной несовместимости с НРА-1а и НРА-1b аллоантигенами плода/новорожденного. В 5 (22%) из 23 семей обнаружена несовместимость по HPA-15 (НРА-15а, n=2, и -15b, n=3), в 1 (4%) семье по НРА-5b и в 1 (4%) семье по НРА-3b аллоантигенам. Заключение. Основными причинами НАИТ в России являются конфликты по НРА-1a и -1b, а вторыми по частоте ‒ конфликты по НРА-15 аллоантигенам.
Ключевые слова: тромбоциты, неонатальная аллоиммунная тромбоцитопения, аллоантигены тромбоцитов человека, российская популяция.

The aim. Mechanisms underlying the development of neonatal alloimmune thrombocytopenia (NAIT) in in Russia have been studied. Materials and methods. Genetic polymorphisms of human platelet alloantigens (HPA) -1, -2, -3, -4, -5, and -15 were evaluated in 27 families having the newborns with NAIT. NAIT was diagnosed according to the following criteria: (1) newborn with thrombocytopenia; (2) mother with no thrombocytopenia and no increase of platelet associated IgG, (3) presence of antibodies reacting with paternal platelets in maternal plasma / serum. HPA genotyping revealed incompatibilities in 23 out of 27 tested families. In these 23 families HPA-1 conflicts were detected in 16 ones (70%). In 8 cases mothers were homozygous carriers of rare HPA-1b allele and in another 8 cases - of HPA-1a allele which cased incompatibilities with fetal HPA-1a and HPA-1b respectively. In 5 out of 23 families (22%) there were incompatibilities with fetal HPA-15 (HPA-15a, n=2 and HPA-15b, n=3), in 1 family - with HPA-5b (4%), and in 1 family – with HPA-3b (4%) alloantigens. In conclusion the main causes of NAIT in Russia were HPA-1a and -1b conflicts and HPA-15 conflicts were the second frequent ones.
Keywords: platelets, neonatal alloimmune thrombocytopenia, human platelet alloantigens, Russian population.
