Eye Institute, Cleveland Clinic Abu Dhabi, Abu Dhabi, United Arab Emirates.
Purpose: To report a case of biopsy-proven sarcoidosis in a patient with panuveitis and a positive interferon-gamma release assay (IGRA) from a non-endemic tuberculosis (TB) country.
Methods: Case report.
Results: A 26-year-old male from the United Arab Emirates (UAE) presented with granulomatous panuveitis characterized by mutton-fat keratic precipitates, anterior chamber and vitreous cells, and retinal vasculitis.
Predictive Markers of Incident Tuberculosis in Close Contacts in Brazil and India.

Programa de Pós-graduação em Ciências da Saúde, Universidade Federal da Bahia, Salvador, Brazil.
There are insufficient predictors of progression to tuberculosis among contacts. A case-control study within RePORT-Brazil matched 20 QuantiFERON-positive progressors and 40 non-progressors by sex, age, and exposure duration. Twenty-nine cytokines were measured by Luminex in QuantiFERON-TB Gold Plus supernatants collected at baseline and evaluated using machine learning for tuberculosis prediction.

BMC Ophthalmol
January 2025
Department of Tuberculosis, New District Branch of Northern Jiangsu People's Hospital of Jiangsu Province, Yangzhou, 225001, Jiangsu Province, China.
Background: This study aims to detect Mycobacterium tuberculosis complex (MTBC) DNA in intraocular fluid from clinically suspected tuberculous uveitis patients using multiplex polymerase chain reaction (PCR) and investigate the diagnostic utility of multiplex PCR for tuberculous uveitis.
Methods: Primers targeting three specific genes (MPB64, CYP141, and IS6110) within the MTBC genome were designed. Multiplex PCR was conducted using DNA from the H37Rv strain as well as DNA extracted from fluids of confirmed tuberculosis patients to assess primer specificity and method feasibility.

Rev Med Chil
June 2024
Sección de Gastroenterología, Hospital Clínico Universidad de Chile, Santiago, Chile.
Intestinal tuberculosis is a bacterial infection that represents 10% of extrapulmonary tuberculosis. It is known as the great mimicker due to its clinical presentation similar to other diseases such as Crohn's Disease or Neoplastic Intestinal Disease. Its diagnosis is complex, given the paucibacillary characteristic of the disease.
