Гемофагоцитарный лимфогистиоцитоз – группа врожденных и приобретенных заболеваний, возникающих вследствие нарушений регуляции иммунного ответа и характеризующихся гиперпродукцией гистиоцитов, а также цитотоксических T-лимфоцитов.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ: оценить взаимосвязь повышенного уровня растворимого интерлейкина-2 альфа в сыворотке крови и исходы поражения почек при гемофагоцитарном лимфогистиоцитозе.</p></sec><sec><title>ПАЦИЕНТЫ И МЕТОДЫ</title><p>ПАЦИЕНТЫ И МЕТОДЫ: В данном типе аналитических (экспериментальных) клинических исследований с дизайном рандомизированных клинических исследований, описанных в метаанализе, были проанализированы результаты обследования 283 пациентов с диагнозом гемофагоцитарный лимфогистиоцитоз и поражением почек. РЕЗУЛЬТАТЫ: при гемофагоцитарном лимфогистиоцитозе относительный риск и отношение шансов повышенного сывороточного уровня растворимого рецептора интерлейкина-2 в сыворотке крови развития почечной недостаточности и начала заместительной почечной терапии составили 1,04 и 1,12 в течение 28 дней соответственно, а межквартильный размах – 35,5 дня. Прогнозируемая вероятность смерти и необходимости начала заместительной почечной терапии при высоком сывороточном уровне растворимого рецептора интерлейкина-2 альфа не были статистически значимыми (р-значение 0,91 и р = 0,56 соответственно). Выявлена сильная отрицательная корреляция между сывороточным уровнем растворимого рецептора интерлейкина-2 альфа и кумулятивной частотой гипонатриемии, протеинурии, острого повреждения почек, азотемии. Статистически значимой взаимосвязи между данными анамнеза и сывороточным уровнем растворимого рецептора интерлейкина-2 альфа не выявлено.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: высокий сывороточный уровень растворимого рецептора интерлейкина-2 в сыворотке альфа взаимосвязан в кумулятивной частотой негативных почечных исходов.</p><p>Дополнительные файлы (Таблицы) расположены по адресу: https://figshare.com/authors/Fateme_Shamekhi_Amiri/9040742 </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: Hemophagocytic lymphohistiocytosis is an uncommon disease with a high mortality rate due to ineffective overactivation of the immune system. THE AIM: to assess the effect and prediction of elevated serum soluble interleukin-2 alpha level on kidney outcomes in hemophagocytic lymphohistiocytosis.</p></sec><sec><title>PATIENTS AND METHODS</title><p>PATIENTS AND METHODS: In this analytic (experimental) clinical studies type with randomized clinical trials design in meta-analysis article, two-hundred eighty-three patients with hemophagocytosis lymphohistiocytosis diagnosis and kidney impairment were investigated.</p></sec><sec><title>RESULTS</title><p>RESULTS: Relative risk and Odds ratio of elevated serum soluble interleukin-2 receptor alpha level on kidney failure progression to kidney replacement therapy was assessed 1.04 and 1.12 during 28 days and interquartile range of 35.5 days in hemophagocytic lymphohistiocytosis in this research. In prediction probability of death and chronic kidney disease progression to end-stage kidney disease led to kidney replacement therapy as outcome using high serum soluble interleukin-2 receptor alpha level was not significant statistically (p-value of 0.91 and p=0.56, respectively). There was strong negative correlation between soluble interleukin-2 receptor alpha levels and cumulative incidence of renal outcomes such as hyponatremia, proteinuria, acute kidney disease, elevated serum blood urea nitrogen and serum creatinine levels with rs of -0.7 and p-value of o.18. There was relationship between serum soluble interleukin-2 receptor alpha level and past medical history (p-value: 0.01) but overall this analysis did not show significant level statistically (p-value: 0.1).</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: There was a strong negative correlation between serum soluble interleukin-2 receptor alpha levels and cumulative incidence of renal outcomes.
