Abstract

Introduction: Opportunistic infections caused by bacteria and fungi are common in human immunodeficiency virus (HIV)-infected patients. Cryptococcus neoformans and Pneumocystis jirovecii are the most common opportunistic infections in immunosuppressed individuals, but their coexistence is rare. To our knowledge, this is the first case presented in Turkey involving the coexistence of C.neoformans fungemia and P.jirovecii pneumonia.

Case Presentation: A 26-year-old male patient presented with a cachectic appearance, cough, sputum, weakness, shortness of breath, and a weight loss of 15 kg in the last three months. It was learned that the patient was diagnosed with HIV three years ago, did not go to follow-ups, and did not use the treatments. CD4 cell count was 7/mm3 (3.4%), CD8 cell count was 100 (54%) mm3, and HIV viral load was 5670 copies/mL. In thorax computed tomography (CT), increases in opacity in diffuse ground glass density in both lungs and fibroatelectasis in lower lobes were observed. With the prediagnosis of P. jiroveci pneumonia, the HIV-infected patient was given trimethoprim-- sulfamethoxazole 15 mg/kg/day intravenously (i.v.). On the 4th day of the patient's hospitalization, mutiplex PCR-based rapid syndromic Biofire (Film Array) blood culture identification 2 (BCID2) test (Biomerieux, France) was applied for rapid identification from blood culture. C. neoformans was detected in the blood culture panel. The treatment that the patient was taking with the diagnosis of C. neoformans fungemia was started at a dose of liposomal amphotericin B 5 mg/kg/- day + fluconazole 800 mg/day.

Conclusion: While the incidence of opportunistic infections has decreased with antiretroviral therapy (ART), it remains a problem in patients who are unaware of being infected with HIV or who fail ART or refuse treatment. High fungal burden, advanced age, low CD4+ cell count, and being underweight are risk factors for mortality in HIV-positive patients. Our case was a cachectic patient with a CD4 count of 7 cells/mm3. Despite the early and effective treatment, the course was fatal.

Keywords: Cryptococcus neoformans, Pneumocystis jirovecii, co-infection, human immunodeficiency virus, case report, antiretroviral therapy.
