Мы представляем клиническое наблюдение больной с ММ с секрецией парапротеина Gκ, у которой развились нефротический синдром, макрогематурия и острое повреждение почек. В биоптате почки в гломерулярной базальной мембране выявлены микротрубочки диаметром 19 нм, организованные в пучки. В результате терапии по программе бортезомиб, циклофосфамид, дексаметазон (BorCyDex) была  достигнута полная ремиссия ММ и ИТГ с полным восстановлением функции почек. Методом повторной биопсии была  доказана резорбция депозитов. В последующем больной была  выполнена аутотрансплантация гемопоэтических стволовых клеток  крови  (ауто-ТГСК). Через 2 года  развился иммунохимический рецидив ММ, признаки нефропатии появились через 4 года  после ауто-ТГСК. В биоптате почки в период рецидива ММ вновь  была  диагностирована ИТГ c толщиной микротрубочек 11–12 нм. Особенностью нашего случая была обильная инфильтрация клубочков лимфоидными клетками с обтурацией просвета капилляров. Мы рассматриваем скопление лимфоидных клеток в просвете капилляров клубочков как особый вариант опухолевого поражения почек при ММ. Лимфоидные клетки  имели признаки плазматизации, в некоторых из них были обнаружены скопления микротрубочек, аналогичных депозитам в почке. Полученные данные подтверждают, что микротрубочки формируются в плазматических клетках, находящихся в просвете клубочковых капилляров, с последующей их миграцией в структуры почки.</p></abstract><trans-abstract xml:lang="en"><p>ITG (immunotactoid glomerulopathy) cases in patients with multiple myeloma (MM) are extremely rare. We present a clinical case of a patient with MM Gκ who developed nephrotic syndrome, macrohematuria and acute kidney injury. Kidney biopsy revealed microtubules in glomerular basement membrane 19 nm in diameter, organized in bundles. The patient was treated with bortezomib, cyclophosphamide and  dexamethasone (BorCyDex) and  achived complete remission after  6 cycles of therapy with a complete renal  function recovery. Repeated renal  biopsy has  revealed a complete resorption of the deposits. Later the patient has  received autologous hematopoietic stem cells  transplantation (auto-HSCT). After 2 years, an immunochemical relapse of MM has  developed. Nephropathy signs have appeared 4 years after  auto-HSCT, ITG was diagnosed again on kidney biopsy during MM relapse with microtubules 11-12 nm in diameter. A special characteristic of our case was excessive glomerular infiltration by the lymphoid cells  with capillary lumen  obstruction. We consider the build-up of lymphoid cells  in the glomerulal capillaries lumen  as a special variant  of renal  tumor lesion  in MM. Lymphoid cells  had  signs of plasmatization. Bundles of microtubules, similar to the deposits in kidneys, were revealed in some of lymphoid cells. The data obtained confirm that microtubules are formed in plasma cells that situated in the lumen  of glomerular capillary vessels and later migrate into renal structures.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>иммунотактоидная гломерулопатия</kwd><kwd>множественная миелома</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Immunotactoid glomerulopathy</kwd><kwd>multiple myeloma</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">RoodIM, LieverseLG, SteenbergenEJ еtal.
