ABSTRACT
BACKGROUND: Histoplasmosis is a systemic mycosis caused by Histoplasma capsulatum (H. capsulatum). Systemic involvement of histoplasmosis usually occurs in immune-compromised patients, patients with AIDS, or those taking immunosuppressive therapy. The present study aims to describe the clinical and laboratory characteristics and treatment outcome of histoplasmosis as the diagnosis is challenging and management protocol differs. METHOD: This retrospective study was done using a data registry at the medicine department of Dhaka Medical College Hospital. Here, patients received the standard treatment of histoplasmosis. Here, patients received the standard treatment of histoplasmosis, and clinical outcome was assessed at 3 months following starting standard treatment. RESULT: A total of nine patients were enrolled, six (66.7%) had systemic histoplasmosis. Three were poultry workers, and the most common comorbidity was diabetes 3 (33.3%). Fever 7 (77.7%), weight loss 6 (66.7%), hyperpigmentation 5 (55.5%), cough 4 (44.4%), oral ulceration 4 (44.4%), lymphadenopathy 4 (44.4%), and hypotension 3 (33.3%) were the most common clinical presentations. Seven (77.7%) out of nine patients were cured of histoplasmosis; however, one died before initiating antifungal medications and another one died due to a hypersensitivity reaction to liposomal amphotericin B. Conclusion: For local histoplasmosis, oral itraconazole is an effective antifungal medication. However, in disseminated Histoplasmosis, liposomal amphotericin B followed by oral itraconazole is still one of the preferable and effective treatment options. Clinicians should be aware of hypersensitivity reactions of liposomal amphotericin B and its management before giving an infusion.
