1 A rapid, accurate and convenient technique for determination of acetylator phenotype of patients or subjects has not been available for routine clinical application. 2 An improved method for rapid and convenient determination of acetylator phenotype is described. 3 The plasma concentrations of dapsone (DDS) and monoacetyldapsone (MAD) were measured 3 h after a single oral 100 mg dose of dapsone using a specific and sensitive high performance liquid chromatographic assay. 4 The plasma concentration ratio of monoacetyldapsone to dapsone can accurately assess acetylator phenotype in patients or subjects. 5 The clinical applications for this method are discussed.

Objective: Heterocyclic amines (HCAs) are mutagens and carcinogens primarily generated when cooking meat at high temperatures or until well-done, and their major metabolic pathway includes hepatic N-hydroxylation via CYP1A2 followed by O-acetylation via N-acetyltransferase 2 (NAT2). NAT2 expresses a well-defined genetic polymorphism in humans resulting in rapid and slow acetylators. Recent epidemiological studies reported significant associations between dietary HCA exposure and insulin resistance and type II diabetes.

Background: Under standard therapies, the incidence of drug-induced liver injury (DILI) in patients with tuberculosis ranges from 2% to 28%. Numerous studies have identified the risk factors for antituberculosis DILI; however, none have been conducted in a multiethnic real-world setting. The primary outcome of the current study was to identify the risk factors that could be used as the best predictors of DILI in a multiethnic cohort.

The N-acetyltransferase 2 (NAT2) gene exhibits substantial genetic diversity, leading to distinct acetylator phenotypes among individuals. In this study, we determine NAT2 gene polymorphisms in tuberculosis (TB) patients and analyze serum isoniazid (INH) concentrations across the various genotypes. An observational prospective cohort study involving 217 patients with pulmonary or extrapulmonary TB was carried out.

Variants in the -acetyltranferase 2 gene, acetylator phenotypes and their association with tuberculosis: Findings in Peruvian patients.

J Clin Tuberc Other Mycobact Dis

Centro de Investigación de Genética y Biología Molecular, Facultad de Medicina Humana, Universidad de San Martín de Porres, Lima, Peru.

Background: Tuberculosis (TB) is a highly prevalent chronic infectious disease in developing countries, with Peru being one of the most affected countries in the world. The variants of the -acetyltransferase 2 () gene are related to xenobiotic metabolism and have potential usefulness in TB studies.

Aim: To determine whether gene variants and acetylator phenotypes are associated with active TB in Peruvian patients.

N-Acetyltransferase 2 gene polymorphism and its serum levels in vitiligo patients.

J Immunoassay Immunochem

November 2024

Medical Biochemistry and Molecular Biology Department, Faculty of Medicine, Menoufia University, Shibin El Kom, Egypt.

Background: Although numerous mechanisms are involved in vitiligo pathogenesis, few studies correlate N-acetyltransferase 2 to this disease.

Aim: To assess the N-acetyltransferase 2 (rs1799929) gene and its serum levels in vitiligo patients.

Subjects And Methods: In this case-control study, 65 vitiligo cases were compared to 65 age- and sex-matched healthy controls.
