A RARE CASE OF PNEUMONIA DUE TO CONCURRENT PNEUMOCYSTIS JIROVECI AND CYTOMEGALOVIRUS INFECTIONS

ABSTRACT

TYPE Case Report TOPIC Chest Infections INTRODUCTION: Cytomegalovirus is an important cause of morbidity and mortality in immunocompromised patients.CMV is an important cause of pneumoina in lung transplant patients too. Pneumocytis Jiroveci (PCP) can casue a potentially life-threatening infection in immunocompromised individuals, especially HIV patients or transplant patients. In our we are presenting a rare case of an immunocompromised patient with penumonia who was infected concurrently with CMV and PCP. CASE PRESENTATION A 53 year-old female patient with history of Rheumatoid Arthritis treated with methotrexate, prednisone and rituximab presented to the emergency room with fatigue and tiredness but no fever. She was tested for COVID-19 and influenza infections (PCR) and both were negative. At presentation, her WBC was 9900. CT with contrast of the chest showed no embolism but multi-focal ground glass opacities. Pulmonary and infectious disease teams were consulted. Blood culture was negative, MRSA screen was negative, Fungitell was positive, LDH test was elevated to 382. CMV quantitaive PCR of 10,000 copies. CMV PCR BAL is detected at 650 copies/ ml, and EBV PCR tests was negative. Pneumocystis Jiroveci pneumonia was detected on BAL DFA. Fungitell waqs more than 500. CMV retinitis has been ruled out by ophthalmology exam. Patient was diagnosed with concurrent infections. Pt was started on Bactrim, valganciclovir PO and intravenous ganciclovir with improvement in her condition. DISCUSSION: It is rare to have a concurrent pneumonia infection caused by Pneumocytis Jiroveci and CMV except in immunocompromised patients. CONCLUSIONS: A concurrent Pneumocystis Jiroveci and CMV pneumonia is a rare infection but could occur in immunocompromised patients. DISCLOSURE Nothing to declare.
