Infections and systemic sclerosis: an emerging challenge

Abstract Mounting evidence has shown non-systemic sclerosis (SSc) related complications as a rising cause of hospital admission and mortality, out of which infections are among the top-five causes. Patients with SSc are at an increased risk of infection due to several features of the treatment options and to the disease itself. For instance, lung involvement is associated with a higher frequency of respiratory infections, whereas the presence of digital ulcers or calcinosis may result in skin and soft tissue infections, and even osteomyelitis. On the other hand, the growing trend towards immunomodulation and immunosuppression in patients with autoimmune diseases will place SSc patients at a higher risk of infectious complications, including opportunistic infections. A low suspicion threshold and an increasing awareness among treating specialists, particularly rheumatologists, are warranted for prevention, early diagnosis and management of infectious complications. Nonetheless, data on risk management strategies in SSc, such as vaccination and antimicrobial prophylaxis, are scarce. A narrative non-systematic review was performed to provide an update of infectious complications in patients with SSc.
