Abstract
Histoplasmosis is a mycosis due to a dimorphic fungus Histoplasma capsulatum. This study aimed at providing an overview of histoplasmosis epidemiological, clinical, diagnostic, and therapeutic aspects from the last 30 years. This review was carried out using a systematic literature search on histoplasmosis from 1992 to 2021. We describe the clinical features, diagnostic methods and treatment. Empirical searches were conducted via the databases PubMed, Google Scholar and Science Direct. Between 1992 and 2021, 190 manuscripts were published and reported 212 cases of histoplasmosis. These publications included 115 and 97 cases of American and African histoplasmosis respectively. The number of publications increased over the last ten years with a maximum in 2020 (12.34 % of the cases reported). The disseminated forms of histoplasmosis were the most frequently reported cases as compared to the localized forms. This was the case with the American histoplasmosis (75.65 %) as well as with the African histoplasmosis (55.67 %). Itraconazole (31.17 %) and Amphotericin B (26.62 %) were the most used drugs in the management of these cases. American histoplasmosis is distributed worldwide whereas African histoplasmosis is mainly present in intertropical Africa. There is a critical need for setting up a global surveillance system, towards a better understanding of the disease.

Abstract
Disseminated histoplasmosis is a life-threatening disease usually seen in immunocompromised patients living in endemic areas. We present an apparently immunocompetent patient with gastrointestinal histoplasmosis who was initially diagnosed with biopsy-proven Crohn's disease. Following discontinuation of anti-inflammatory drugs and institution of antifungal therapy, his gastrointestinal illness completely improved. Specific fungal staining should be routinely included in histopathologic assessment of tissue specimens diagnosed as Crohn's disease.

A Rare Presentation of Possible Disseminated Histoplasmosis with Adrenal Insufficiency Leading to Adrenal Crisis in an Immunocompetent Adult: A Case Report. Case Rep Med 2020; 2020:8506746. [PMID: 32256604 PMCID: PMC7103037 DOI: 10.1155/2020/8506746] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2019] [Accepted: 02/14/2020] [Indexed: 11/24/2022] Open
Abstract
Histoplasmosis is caused by Histoplasma capsulatum, and commonly it causes an asymptomatic illness. Although Histoplasma is the commonest organism to infect adrenal glands, disseminated histoplasmosis in an immune-competent host leading to adrenal insufficiency is rare in current literature. Here, we report a case of possible disseminated histoplasmosis leading to adrenal crisis in a young Asian immunocompetent male. A 42-year-old Sri Lankan male with noninsulin-dependent diabetes mellitus presented with constitutional symptoms and feverishness for three weeks' duration. He was found to have hepatosplenomegaly with bilateral adrenal masses and pancytopenia. One week later, he developed severe vomiting and hemodynamic collapse and was found to have suppressed adrenal functions. Ultrasound-guided biopsy of adrenals showed fungal spores morphologically similar to Histoplasma. He was started on oral itraconazole and adrenal replacement therapy. He improved symptomatically with treatment and currently is on regular clinic follow-up with a plan to continue antifungal therapy for at least one year to prevent a relapse. Fungal infections, especially histoplasmosis, need to be considered in all immunocompetent patients with compatible history and bilateral adrenal masses. Adrenal insufficiency needs to be promptly diagnosed and treated to prevent Addisonian crisis in these patients.
