We report a case of disseminated histoplasmosis and COVID-19 infection in a renal transplant recipient in Argentina. The patient exhibited respiratory symptoms, and a chest computed tomography scan (CT) showed multiple bilateral centrilobular opacities with a tree-in-bud pattern in both lobes. The patient was initially treated as having bacterial community-acquired pneumonia, and then tuberculosis. A month later, histoplasmosis was diagnosed, and Histoplasma capsulatum LAmB clade was isolated from sputum, skin and oral lesions. The patient was hospitalized and treatment was started with intravenous liposomal amphotericin B. During the course of the antifungal therapy the respiratory symptoms worsened, a new chest CT showed a unilateral lesion with a ground glass appearance and SARS-CoV-2 was detected in a new nasopharyngeal sample. In addition, plasma therapy was administered, and the immunosuppressive regimen was adjusted (everolimus was interrupted, mycophenolate mofetil reduced, and meprednisone increased). Finally, the patient's progress was favorable and was discharged after five days on oral itraconazole treatment for histoplasmosis.
Se presenta un caso de histoplasmosis diseminada e infección por COVID-19 en un paciente trasplantado renal en Argentina. El paciente presentó un cuadro clínico respiratorio, y la tomografía computarizada (TC) de tórax mostró múltiples opacidades centrolobulillares bilaterales con patrón de árbol en brote. El paciente fue tratado inicialmente con antibióticos para agentes causantes de neumonía bacteriana adquirida en la comunidad y luego como tuberculosis. Un mes después se le diagnosticó una histoplasmosis diseminada y el hongo fue aislado del esputo, la piel y la mucosa oral. El hongo fue tipificado molecularmente como Histoplasma capsulatum clado LAmB. El paciente fue hospitalizado y se inició tratamiento con anfotericina B liposomal vía intravenosa. Durante el transcurso de la terapia antifúngica los síntomas respiratorios del paciente empeoraron, una nueva TC de tórax mostró una lesión unilateral con apariencia de vidrio esmerilado y se detectó SARS-CoV-2 en el hisopado nasofaríngeo. El paciente fue tratado con plasm |
