Pathogenic variants in the subunit 1 of nuclear factor κB are thought to be one of the most frequent monogenic causes of common variable immunodeficiency. Besides the humoral immunodeficiency, <italic>NFKB1</italic> defect is characterized by a wide range of autoimmune, autoinflammatory and hematological features. To date, there are no standardized guidelines for immunosuppressive or anti-inflammatory therapy in patients with <italic>NFKB1 </italic>deficiency.</p> <p>We report on a 62 year old woman with common variable immunodeficiency due to heterozygous mutation in the <italic>NFKB1 </italic>gene, complicated by a systemic form of Still’s disease. Since initiation of the anti-cytokine therapy with the interleukin 6 antagonist olokizumab, resolution of constitutional symptoms has been achieved. Over the 1.5-years follow-up there has been an improvement on lymphadenopathy and joint syndrome according to computed tomography scan and ultrasound.</p> <p>Variety of manifestations of immune disregulation in complex of symptoms of <italic>NFKB1</italic> defect forces a neccessity of awareness of the specialists and requires a multidisciplinary approach to selection of an optimal tactic to patient treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Общая вариабельная иммунная недостаточность — наиболее распространенная форма врожденных дефектов иммунитета, однако ее генетическая причина известна менее чем в трети случаев.
