Моноклональная гаммапатия (МГ) неопределенного значения (MGUS) является не только предопухолевым состоянием, предшествующим развитию множественной миеломы (ММ) и других секретирующих опухолей, но и возможной причиной заболеваний неопухолевой природы, в том числе поражения почек Цель исследования. Оценить информативность методов «Freelite», в добавление к электрофорезу (ЭФ) и иммунофиксации (ИФ) белков сыворотки и мочи, для выявления МГ у больных с поражением почек. Материалы и методы. Из 113 больных с МГ было отобрано 87 больных с поражением почек, у которых МГ установлена при использовании метода ЭФ белков сыворотки, ИФ и метода определения свободных легких цепей – FLC «Freelite». Проведена оценка эффективности в диагностике МГ этой трехкомпонентной сывороточной панели. Результаты и обсуждение. Из 87 больных с поражением почек МГ была определена у 39 (45%) пациентов с AL-амилоидозом, 16 (18%) – с (HCV+) криоглобулинемическим гломерулонефритом (крио-ГН), 28 (32%) – с хроническим ГН (ХГН), 4 (4%) – с болезнью отложения легких цепей (БОЛЦ) с помощью трехкомпонентной скрининговой панели. Определение МГ с помощью ЭФ было возможным только у 38 (44%) больных. Добавление к сывороточным электрофоретическим методам вместо метода «Freelite» ЭФ и ИФ мочи уменьшило число пропущенных больных с моноклональной гаммапатией – в целом с 24 (27%) до 11 (13%), но не достигло чувствительности трехкомпонентной сывороточной скрининговой панели. У 10 (11,5%) пациентов МГ была представлена только интактными mIg с одним типом легких цепей – либо κ, либо λ. Наиболее часто – у 25% больных – интактная МГ наблюдалась при HCV(+) крио-ГН. У 37 (42,5%) пациентов выявлена комбинация интактных mIgM, mIgG или mIgA с mFLC. Почти у половины (46%) больных обнаружены только mFLC – анормальное отношение κ/λ. Заключение. Трехкомпонентная сывороточная скрининговая панель ЭФ+ИФ+«Freelite» расширяет возможности распознавания МГ малого объема (MGUS) и должна быть введена в алгоритм обследования больных нефрологического профиля.
Ключевые слова: моноклональная гаммапатия, метод иммунофиксации, Freelite, амилоидоз, хронический гломерулонефрит.

Мonoclonal gammopathy (MG) is not only the state preceding of hematological neoplasms, but also associated with non-hematological diseases, in particular kidney damage. Aim. To assess the diagnostic value of “Freelite” methods in addition to electrophoresis (EF) and immunofixation (IF) of serum and urine proteins for detecting MG in patients with kidney diseases. Materials and methods. 87 patients with kidney damage, in which MG was established using the method of electrophoresis of serum proteins (EF), immunofixation (IF) and the method of free light chains determination – FLC “Freelite” were selected. The diagnostic value of three-component serum panel was compared with EF and IF. Results and discussion. AL-amyloidosis with kidney involvement was diagnosed in 41% patients, cryoglobulinemic glomerulonephritis (cryo GN) – in 18%, chronic glomerulonephritis (CGN) – in 35%, also there was small number of patients with light chain disease and cast-nephropathy. Determination of MG using EP was possible only in 38 (44%). Adding to the serum electrophoretic methods instead of the “Freelite” method, the urine EF and IF reduced the number of missed patients with monoclonal gammopathy from 24 (27%) to 11 (13%), including in the subgroup of patients with AL-amyloidosis but did not reach the sensitivity of the three-component serum screening panel. In 10 (11.5%) MG was represented only by intact mIg with one type of light chain, either κ or λ. Most often – in 25% of patients, intact monoclonal gammopathy was observed in HCV (+) cryo GN. A combination of intact mIgM, mIgG or mIgA with mFLC, was detected in 37 (42.5%). In almost half (46%) of the patients, only mFLC was detected – an abnormal κ/λ ratio. Conclusion: The serum screening panel EF + IF + “Freelite” spreads the low-grade monoclonal gammopathy recognition (MGUS) and should be included in the algorithm of examining patients with kidney disease.
Keywords: monoclonal gammopathy, immunofixation of proteins, “Freelite”, amyloidosis, chronic glomerulonephritis.
