Introduction: Cogan's syndrome (CS) is a rare autoimmune disease, characterized by ocular and vestibulo-auditory involvement. Treatment of CS could be challenging, and the only evidence-based data comes from case reports or series. Areas covered: There have recently been several reports of new treatment strategy involving the use of biological disease-modifying anti-rheumatic drugs such as TNFα inhibitors, anti-CD20 or anti-IL6 receptor antibodies, in cases resistant to first- or second-line drugs. Expert commentary: Corticosteroids are the cornerstone of CS therapy at disease onset and during acute phases of the disease. Conventional immunosuppressive therapy, such as methotrexate, could be used in relapsing patients or as a glucocorticoid sparing agent, but efficacy is often modest. The anti-TNFα monoclonal antibody Infliximab appears to be the most frequently used, leading to an improvement in hearing loss in 89% of the cases and allow corticosteroid tapering in 86% of the patients. The appropriate timing of Infliximab treatment has yet to be thoroughly investigated, but it seems to be more effective when started at an early stage of the disease. Efficacy of others anti-TNFα agents is controversial. Rituximab and Tocilizumab are a safe option, but results on hearing loss have still to be confirmed on larger patients' cohorts.

Abstract

Introduction: Cogan's syndrome (CS) is a rare autoimmune disease, characterized by ocular and vestibulo-auditory involvement. Treatment of CS could be challenging, and the only evidence-based data comes from case reports or series. Areas covered: There have recently been several reports of new treatment strategy involving the use of biological disease-modifying anti-rheumatic drugs such as TNFα inhibitors, anti-CD20 or anti-IL6 receptor antibodies, in cases resistant to first- or second-line drugs. Expert commentary: Corticosteroids are the cornerstone of CS therapy at disease onset and during acute phases of the disease. Conventional immunosuppressive therapy, such as methotrexate, could be used in relapsing patients or as a glucocorticoid sparing agent, but efficacy is often modest. The anti-TNFα monoclonal antibody Infliximab appears to be the most frequently used, leading to an improvement in hearing loss in 89% of the cases and allow corticosteroid tapering in 86% of the patients. The appropriate timing of Infliximab treatment has yet to be thoroughly investigated, but it seems to be more effective when started at an early stage of the disease. Efficacy of others anti-TNFα agents is controversial. Rituximab and Tocilizumab are a safe option, but results on hearing loss have still to be confirmed on larger patients' cohorts.
