RESUMO
This article reports on a 38-year-old kidney transplant patient who presented with fever, coughing and dypnea. The patient was immunosuppressed with mycophenolate and prednisone. Due to the suspicion of community acquired pneumonia antibiotic treatment was initiated and the patient was admitted to the intensive care unit. Despite antibiotic treatment the condition did not improve and in the subsequently performed bronchioalveolar lavage parainfluenza virus was diagnosed.Infections with respiratory viruses can be fatal in immunosuppressed patients. Human parainfluenza virus is the third most common pathogen of viral pneumonia. Molecular genetic detection methods allow fast and sensitive diagnosis of respiratory materials. As the treatment options are limited for these infections prophylactic measurements are important.
