Cardiac sarcoidosis: systematic review of literature on corticosteroid and immunosuppressive therapies

Abstract : Background Cardiac sarcoidosis (CS) is a life-threatening condition in which clear recommendations are lacking. We aimed to review systematically the literature on cardiac sarcoidosis treated by corticosteroids and/or immunosuppressive agents in order to update the management of CS. Methods Using Pubmed, Embase and Cochrane Library databases, we found original articles on corticosteroid and/or standard immunosuppressive therapies for CS which provided at least fair SIGN overall assessment of quality and analyse the relapse rate, major cardiac adverse events (MACEs) and adverse events. We base our methods on Prisma statement and checklist. Results We retrieved 21 studies. Mean quality provided by SIGN assessment was 6.8/14 (range 5–9). Corticosteroids appeared to have a positive impact on left ventricular function, atrioventricular block, and ventricular arrhythmias. For corticosteroids alone, nine (45%) studies (n=351) provided data on relapses, representing an incidence of 34% (n=119). Three studies (14%, n=73) provided data on MACEs (n=33), representing 45% of MACEs in patients treated by corticosteroid alone. Nine studies provided data on adjunctive immunosuppressive therapy in which four studies (n=78) provided data on CS relapse, representing an incidence of 33% (n=26). Limitations consisted in no randomised control trial retrieved and unclear data on MACEs in patients treated by combined immunosuppressive agents and corticosteroids. Conclusions Corticosteroids should be started early after diagnosis but the exact scheme is still unclear. Studies concerning adjunctive conventional immunosuppressive therapies are lacking and benefits of adjunctive immunosuppressive therapies are unclear. Homogenous data on CS long-term outcomes under corticosteroids, immunosuppressive therapies and other adjunctive therapies are lacking.
