Hemophagocytic Lymphohistiocytosis in the Setting of Disseminated Histoplasmosis and Uncontrolled HIV.

Cureus 2022 Apr 21;14(4):e24360. Epub 2022 Apr 21.

Internal Medicine, The University of Tennessee Health Science Center at Chattanooga, Chattanooga, USA.

Hemophagocytic lymphohistiocytosis (HLH) is a rare and life-threateningly aggressive syndrome caused by excessive immune activation. It involves the abnormal activation of lymphocytes and macrophages which leads to tissue destruction and inflammation. Traditionally HLH classification is currently separated into primary and secondary HLH based on genetic versus nongenetic events such as infection, malignancy, or autoimmune disorders. Read More

Notch regulates Histoplasma capsulatum clearance in mouse lungs during innate and adaptive immune response phases in primary infection.

J Leukoc Biol 2022 May 23. Epub 2022 May 23.

Department of Medicine, Division of Infectious Diseases, University of Cincinnati College of Medicine, Cincinnati, Ohio, USA, 234 Albert Sabin Way, Cincinnati, OH, 45267, United States.

The clearance of the pathogenic fungus, Histoplasma capsulatum, requires cooperation between innate and adaptive immunity. Since this organism is inhaled, lung macrophages and dendritic cells (DCs) are the first lines of defense. Moreover, DCs act as APCs to drive the education of type 1 Th cells to produce IFNγ, which contributes to the final elimination of H. Read More

Integrating Public Health Surveillance and Environmental Data to Model Presence of Histoplasma in the United States.

Epidemiology 2022 May 5. Epub 2022 May 5.

Biostatistics and Data Science, Wake Forest School of Medicine, Winston-Salem, NC.

Background: In the United States, the true geographic distribution of the environmental fungus Histoplasma capsulatum remains poorly understood but appears to have changed since it was first characterized. Histoplasmosis is caused by inhalation of the fungus and can range in severity from asymptomatic to life-threatening. Due to limited public health surveillance and under detection of infections, it is challenging to directly use reported case data to characterize spatial risk. Read More

Histoplasmosis acquired in Alberta, Canada: an epidemiological and genomic study.

Lancet Microbe 2021 May 3;2(5):e191-e197. Epub 2021 Mar 3.

Division of Infectious Diseases, Department of Medicine, University of Alberta, Edmonton, AB, Canada.

Background: The classic geographical range of histoplasmosis in North America primarily includes the states and provinces adjacent to the Ohio, Mississippi, and St Lawrence riverways. Although Alberta, Canada is not typically considered a region of risk for histoplasmosis, cases with suspected local acquisition have been reported. We aimed to investigate the epidemiology and geographical distribution of cases of histoplasmosis in Alberta to assess evidence for local acquisition of infections, using genomic analysis for corroboration.

Mycoses 2022 Apr 28. Epub 2022 Apr 28.

Durham County Department of Public Health, Durham, North Carolina, USA.

Biological sex, which comprises differences in host sex hormone homeostasis and immune responses, can have a substantial impact on the epidemiology of infectious diseases. Comprehensive data on sex distributions in invasive fungal diseases (IFDs) are lacking. In this review, we performed a literature search of in vitro/animal studies, clinical studies, systematic reviews and meta-analyses of invasive fungal infections. Read More

Histoplasmosis masquerading as tuberculosis: A report of three cases in immunocompetent children.

Indian J Pathol Microbiol 2022 Apr-Jun;65(2):406-409

Department of Pediatric Surgery, IPGMER, Kolkata, West Bengal, India.

The most common cause of granulomatous lymphadenitis in countries like ours is mycobactrium tuberculosis followed by atypical mycobacterial infection, fungal infections, parasitic infection, cat scratch disease, lymphogranuloma venereum (inguinal lymphadenopathy), and leprosy Here, we present three cases of lymphadenopathy due to histoplasmosis in immunocompetent children. Two of them presented with fever, lymphadenopathy, initially diagnosed as granulomatous lymphadenitis consistent with tuberculosis on FNAC and were put on antitubercular drugs.

Lung and Mediastinal Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration in Young Adults.

Acta Cytol 2022 Apr 7:1-10. Epub 2022 Apr 7.

Pathology and Laboratory Medicine, Cleveland Clinic, Cleveland, Ohio, USA.

Introduction: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is used to investigate pulmonary nodules, mediastinal lymphadenopathy, and mediastinal masses in both malignant and nonmalignant etiologies. EBUS-TBNA is most commonly used in the diagnosis and staging of patients with non-small-cell lung cancer in the middle-age and elderly populations. As lung cancer is uncommon in young adults, it is assumed that there are a distinct disease population and clinical background in young adults who undergo EBUS-TBNA. Read More

Department of Cardiovascular Medicine, Heart and Vascular Institute, Cleveland Clinic Foundation, 9500 Euclid Ave, Cleveland, OH 44195, USA.

Background: Diagnosis of fungal endocarditis can be challenging, especially among cases with negative blood culture results. Of fungal endocarditis cases, constitutes an even smaller proportion with ∼58 prior cases reported. Due to the rarity of histoplasmosis endocarditis and thus limited data, there is no current diagnostic guideline for testing within culture negative infective endocarditis. Read More

Faculty of Medicine, "Ovidius" University of Constanta, 900470 Constanta, Romania.

Lesions commonly associated with HIV infection include oral candidiasis, herpes simplex infection, oral Kaposi's sarcoma, hairy leukoplakia, periodontal diseases (linear gingival erythema and necrotizing ulcerative periodontitis), xerostomia, human papillomavirus-associated warts, aphthous ulcers, non-Hodgkin's lymphoma, histoplasmosis, carcinoma, exfoliative cheilitis, and HIV salivary gland disease. Non-Hodgkin's lymphoma (NHL) is the most common cancer in people living with HIV (PLWH), and the incidence is increased for aggressive B-cell NHL. Plasmablastic lymphoma (PbL) is a rare and aggressive B-cell malignancy that is often unresponsive to chemotherapy and usually has a poor prognosis. Read More

Retraction: Histoplasmosis affecting oral mucosa in an immunocompetent patient: A rarity in non-disseminated disease.

Authors:

Indian J Dermatol Venereol Leprol 2022 Mar-Apr;88(2):277

The article titled "Histoplasmosis affecting oral mucosa in an immunocompetent patient: A rarity in non-disseminated disease"1, published on pages 214-216, issue 2, volume 88 of the Indian Journal ofDermatology, Venereology, and Leprology (IJDVL), has been retracted by the Editorial Board of the journal following an investigation. It has been noted that Figure 2 of their published article is the one and the same as the upper panel of Figure 3 of another article published by Sen et al in the Indian Journal Dermatology (IJD). Also, the Editorial Board notes the fact that neither did the authors cite the earlier published article in the article published in the current issue of our journal, nor did they offer any explanation for the same when specifically queried upon why they had not done that.
