Моноклональная гаммапатия (МГ) рассматривается в настоящее время не только как состояние, предшествующее развитию гематологических неоплазм, но также и некоторых неопухолевых заболеваний, в частности поражения почек, что представляет высокоактуальную проблему. ЦЕЛЬ. Определить распространенность и варианты моноклональной гаммапатии (МГ) среди терапевтических больных, в том числе с неопухолевыми поражениями почек, для оптимизации методов их диагностики и определения тактики лечения. ПАЦИЕНТЫ И МЕТОДЫ. Всего проанализировано 11392 больных в течение 4 лет (2013–2016 гг.). Проводилось стандартное общеклиническое обследование, принятое в отделениях многопрофильного стационара. Для выявления МГ были использованы метод электрофореза белков сыворотки крови и 24-часовой концентрированной мочи, метод иммунофиксации белков сыворотки крови и мочи и метод определения свободных легких цепей в сыворотке крови (Freelite). РЕЗУЛЬТАТЫ. МГ диагностирована у 174 из 11392 больных: 49 % мужчин и 51 % женщин в возрасте от 18 до 85 лет и выявлялась в 2,1 раза чаще у больных нефрологического профиля. Среди больных этой группы у 41 % диагностирован AL-амилоидоз с поражением почек, у 18 % – криоглобулинемический гломерулонефрит, у 35 % – хронический гломерулонефрит и у небольшого числа больных – болезнь отложения легких цепей с поражением почек и cast-нефропатия. У 86 % больных нефрологического профиля величина МГ была менее 5 г/л, что соответствует олигосекреторной МГ, причем у 46 % из них – менее 1 г/л, еще 10 % имели величину МГ 5–10 г/л, и только у 4,42 % больных определены значения более 10 г/л. ЗАКЛЮЧЕНИЕ. Определено важное значение МГ в патогенезе поражения почек, особенно ее олигосекреторной формы, что требует применения у больных нефрологического профиля более чувствительных методов исследования МГиммунофиксации и Freelite.</p></abstract><trans-abstract xml:lang="en"><p>BACKGROUND. Мonoclonal gammopathy (MG) is not only the state preceding of hematological neoplasms, but also associated with non- hematological diseases, in particular damage of kidneys. Earlier diagnosis of MG represents an important area in treating patients with renal diseases associated with MG. THE AIM: To determine the frequency of MG among therapeutic and nephrological patients for optimization of methods of their diagnosis and treatment. PATIENTS AND METHODS: In common, 11392 patients were analyzed within 4 years (2013-2016). The standard clinical examination was conducted. Method of an electrophoresis of proteins of serum of blood and the 24-hour urine, method of immunofixation of proteins of serum and urine, and method of free light chains definition in serum (Freelite) were used for MG identification. RESULTS: MG is diagnosed in 174 of 11392 patients: 49 % of men and 51 % of women aged from 18 up to 85 years. MG was found 2.1 times more often in nephrological patient than in patients of therapeutic departments. Among patients of this group, AL-amyloidosis with kidney involvement was diagnosed in 41 %, cryoglobulinemic glomerulonephritis – in 18 %, chronic glomerulonephritis – in 35 %, also there was small number of patients with light chain disease and cast-nephropathy. 86 % of nephrological patients had less than 5 g/l of monoclonal protein that corresponds oligo secretory MG, and at 46 % from them – less than 1 g/l, other 10 % had MG of 5-10 g/l, and only in 4.42 % of patients MG more 10g/l was defined. CONCLUSION: We conclude that MG, especially oligo secretory form, play a significant role in pathogenesis of renal damage. It is important to apply sensitive methods – immunofixation of proteins and method «Freelite» for nephrological patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>моноклональная гаммапатия</kwd><kwd>метод иммунофиксации</kwd><kwd>Freelite</kwd><kwd>амилоидоз</kwd><kwd>хронический гломерулонефрит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>monoclonal gammopathy</kwd><kwd>immunofixation of proteins</kwd><kwd>Freelite</kwd><kwd>amyloidosis</kwd><kwd>chronic glomerulonephritis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kyle R, Rajkumar S/ Monoclonal gammopathy of undetermined significance and smouldering multiple myeloma: emphasis on risk factors for progression.
