Jansen AFM, et al. - Via a study on identified Q fever patients, the researchers intended to increase awareness of concomitant chronic Q fever infection and systemic sclerosis and to provide insight into the course of systemic sclerosis during persistent Q fever infection. Shortly preceded or followed by the diagnosis of limited cutaneous systemic sclerosis, 4 cases of chronic Q fever persistent Coxiella burnetii infection were presented. A mild course of systemic sclerosis without the necessity of immunosuppressive drugs was associated with chronic Q fever preceding systemic sclerosis. Although, correlation among chronic Q fever development due to immunocompromised state and a more deteriorating course of systemic sclerosis was noted.
