Pleural effusion as a manifestation of a Cryptococcal infection in an HIV patient

Diagnosis of invasive cryptococcal infection in apparently nonimmunocompromised patients is difficult and often delayed. Human immunodeficiency virus- (HIV-) negative patients with decompensated hepatic cirrhosis might be at high risk of cryptococcal infection. We report here an 82-year-old Japanese female with end-stage hepatic failure and undergoing renal dialysis, hospitalized with septic shock-like symptoms. The patient had had hepatitis B virus (HBV) infection in the past. She survived only 4 days following admission. During hospitalization, she was found to have pleural effusion and ascites. Cryptococcus neoformans was obtained from blood culture but not from pleural effusion culture. Consequently, the patient was diagnosed as having invasive cryptococcosis in association with HBV-related hepatic cirrhosis. Unfortunately, the patient died prior to receiving antifungal agents. Twelve Japanese cases of hepatic cirrhosis-related invasive cryptococcal infection, consisting of previously described and this case, were summarized for discussion of the clinical features and outcomes.

Abstract Background Cryptococcal infections are frequently seen in immunosuppressed hosts. To date, few cases of cryptococcal infections presenting solely as pleural effusion have been described in liver transplant recipients. To our knowledge, this is the first case of cryptococcal pleuritis presenting with acute respiratory failure early post liver transplant. Methods 51- year old male with non- alcoholic cirrhosis complicated by chronic right hydrothorax underwent deceased donor liver transplantation with methylprednisolone induction. A week later, he developed acute respiratory failure requiring intubation. Pleural fluid was exudative with lymphocyte predominance; aerobic culture grew C. neoformans. Serum cryptococcal antigen was initially negative (prozone phenomenon was excluded) and subsequently turned positive titer 1:16. He was started on liposomal amphotericin and flucytosine, but developed acute kidney injury; induction therapy was changed to fluconazole with flucytosine for 2 weeks followed by fluconazole consolidation for 8 weeks. He remains on maintenance therapy. Donor serum cryptococcal antigen was negative, and recipients of other organs from the donor were clinically well. Results Pleural effusions are common in cirrhotic patients with ascites from hepatic hydrothorax. Although rare, Cryptococcal infection can manifest as isolated pleural effusion. Our patient was diagnosed with Cryptococcal empyema early post-transplant, though likely had subclinical or latent infection pre-transplant; evaluation for donor-derived infection was negative. Diagnosis of isolated pleural disease may be missed if only serum Cryptococcal antigen is tested, as antigen may not be detectable. Diagnosis is mainly established by pleural fluid culture and may be delayed, as pleural fluid is not routinely cultured when effusions are attributed to hepatic hydrothorax. Cryptococcal antigen in the pleural fluid may have a better diagnostic yield. Conclusion Cryptococcal infection should be considered in patients with cirrhosis and liver transplant recipients presenting with pleural effusion without any other abnormalities on chest imaging. Diagnosis may be missed if only serum cryptococcal antigen is used. Disclosures All Authors: No reported disclosures
