A 15-year-old boy with severe combined immunodeficiency, fungal infection, and weight gain.

Hematopoietic stem cell transplantation (HSCT) outcomes in X-linked severe combined immune deficiency are most effective when performed with patients <3 months of age and without coexisting morbidity, and with donor cells from a matched sibling. Even under such favorable circumstances, outcomes can be suboptimal, and full cellular engraftment may not be complete, which results in poor B or natural killer cell function. Protein losing enteropathies can accompany persistent immune deficiency disorders with resultant low serum globulins (immunoglobulin A [IgA], IgG, IgM) and lymphopenia. Patients

Fatal histoplasmosis in a non-HIV patient in French Guiana.

Histoplasmosis is an endemic fungal infection that causes no symptoms or minor self-limited illnesses in most cases. Severe forms are commonly reported in patients with immunodeficiency disorders; histoplasmosis is considered to be an opportunistic infection in patients with AIDS. We report a case of disseminated histoplasmosis in a patient with no induced active suppression of the immune response. The infection was fulminant, and antifungal treatment was delayed because of a misdiagnosis of tuberculosis.

Histoplasmosis: results of the Colombian national survey, 1992-2008.

INTRODUCTION: Histoplasmosis, a fungal disorder characterized by a wide spectrum of manifestations that range from subclinical infections to disseminated processes, affects both immunocompetent and immunosuppressed individuals. Histoplasmosis is not a reportable disease in Colombia and consequently, a survey was designed to collect histoplasmosis cases diagnosed in the country. OBJECTIVE: The aim of this work was to analyze the data collected from 1992 to 2008. Materials and methods. The survey included demographic data, risk factors, clinical manifestations, imaging data, diagnostic methods

Fatal gastrointestinal histoplasmosis 15 years after orthotopic liver transplantation.

We report a case of ileo-colonic Histoplasmosis without apparent respiratory involvement in a patient who had previously undergone an orthotopic liver transplant (OLT) for primary biliary cholangitis 15 years earlier. The recipient lived in the United Kingdom, a non-endemic region for Histoplasmosis. However, she had previously lived in rural southern Africa prior to her OLT. The patient presented with iron deficiency anaemia, diarrhoea, abdominal pain and progressive weight loss. She reported no previous foreign travel, however, it later became known that following her OLT she had been on hol

Neuroinfections caused by fungi.

BACKGROUND: Fungal infections of the central nervous system (FIs-CNS) have become significantly more common over the past 2 decades. Invasio … omycetes (Mucor spp., Rhizopus spp.), dimorphic fungi (Blastomyces dermatitidis, Coccidioides spp., Histoplasma capsulatum), and dematiaceous fungi (Cladophialophora bantiana, Exophiala dermatitidis). Their common route of transmission is inhalation or inoculation from trauma or surgery, with subsequent hematogenous or contiguous spread. As the manifestations …

Chronic Meningitis Investigated via Metagenomic Next-Generation Sequencing.

IMPORTANCE: Identifying infectious causes of subacute or chronic meningitis can be challenging. Enhanced, unbiased diagnostic approaches are … ium, in 2 participants), a virus (HIV-1), and 4 fungi (Cryptococcus neoformans, Aspergillus oryzae, Histoplasma capsulatum, and Candida dubliniensis) were identified among the 7 participants by using mNGS. Evaluating mNGS data with a weighted z score-based scoring algorithm reduced the reported microbial taxa by a mean of 87% (range, 41%-99%) when taxa with a …

Gastrointestinal histoplasmosis in a patient after autologous stem cell transplant for multiple myeloma.

A 59-year-old patient with multiple myeloma on maintenance chemotherapy presented with fever, weight loss, and night sweats. An F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) computed tomography (CT) showed intra-abdominal lymphadenopathy with a mesenteric mass that led to further workup and diagnosis of histoplamosis. The patient was treated with amphotericin B and subsequently switched to itraconazole. This exemplifies the usefulness of FDG PET CT in diagnosis of infectious complications.

PET-CT scan positive pulmonary nodule revealing histoplasmosis: a case report.

Our medical staff identified a case of a forty-six years old Armed Force active duty female that presented with multiple systemic and pulmonary signs and symptoms, such as hemoptysis, arthralgias, chest pain and dyspnea after being exposed to a humid and old wooden building one year ago in the state of Georgia. Various imaging studies (cervical & thoracic x-rays and CT Scans), revealed diffuse small nodules at cervical & thoracic areas, osteolytic lesions and lymphadenopathy. Suspecting a malignant process, a PET-CT Scan was performed revealing a right lung lower lobe nodule consistent with a

Fever in hospitalized HIV-infected patients in Western French Guiana: first think histoplasmosis.

In Western French Guiana, there was a dramatic increase in HIV prevalence between 1990 and 2000. The present study describes the causes of fever among HIV patients hospitalized in the medical ward of the only hospital in the western part of French Guiana. A retrospective descriptive study was conducted between 1 January 2008 and 30 June 2010 in the department of medicine of Saint Laurent du Maroni Hospital. The main characteristics of 67 patients having presented with fever in the first 48 hours of hospitalization were described. Among patients with CD4 <200/mm(3)the main febrile opportunistic

Evaluation of a microtiter latex agglutination test for histoplasmosis.

Experiments were designed to evaluate a Microtiter latex agglutination (Micro-LA) test, as a serological aid in the diagnosis of histoplasmosis, and to compare this test with the conventional microtiter-complement fixation (CF) test for histoplasmosis. Sera tested were from cases of acute and chronic pulmonary and disseminated histoplasmosis, as well as from individuals not having histoplasmosis. Ninety-seven percent of the cases of acute pulmonary histoplasmosis had positive Micro-LA tests, whereas 91% had positive CF tests. Ninety-six percent of the patients having chronic pulmonary histopla

Re-estimation of the burden of serious fungal diseases in Uganda.

BACKGROUND: It is of utmost importance to monitor any change in the epidemiology of fungal diseases that may arise from a change in the number of the at-risk population or the availability of local data. OBJECTIVE: We sought to update the 2015 publication on the incidence and prevalence of serious fungal diseases in Uganda. METHODS: Using the Leading International Fungal Education methodology, we reviewed published data on fungal diseases and drivers of fungal diseases in Uganda. Regional or global data were used where there were no Ugandan data. RESULTS: With a population of ~45 million, w
