Abstract
Infections are among the most serious complications in patients with systemic lupus erythematosus (SLE), with bacterial and viral infections being the most common. Non-tuberculous mycobacterial (NTM) infections are quite rare and are typically seen in older patients with SLE with longstanding disease duration treated with corticosteroids. Here, we describe a 39-year-old woman with SLE and an unusual pattern of recurrent NTM disseminated infections. After excluding the presence of autoantibodies against interferon-γ, whole exome sequencing revealed a homozygous polymorphism in the NF-kappa-B essential modulator (NEMO) gene. Primary immunodeficiencies should be included in the differential diagnosis of patients with recurrent opportunistic infections, even in those with iatrogenic immunosuppression.
