Abstrakt: Pneumocystis jirovecii pneumonia (PJP) is a potentially fatal type of pneumonitis, which may have devastating consequences. Typically, it occurs in immunocompromised patients, with the natural history varying depending on the presence or not of HIV infection. Staining and polymerase chain reaction (PCR) testing in induced sputum or bronchoalveolar lavage (BAL) is the cornerstone of the diagnosis, while trimethoprim-sulfamethoxazole is the treatment of choice. The etiological association of biologic agents with the occurrence of PJP is not entirely clear. Adalimumab is a fully human monoclonal anti-TNF-alpha antibody, which has been introduced relatively recently in the treatment of autoimmune inflammatory diseases, such as rheumatoid arthritis. In contrast to other biologic agents, such as Alemtuzumab or Infliximab, there are a small number of reports that support the drug's ability to trigger the occurrence of PJP. Hereby, we present a 53-year-old female patient with a medical history of rheumatoid arthritis on Adalimumab therapy, who developed PJP and we will discuss the main characteristics of PJP and the possible contribution of biologics to the occurrence of the infection.
