Infection with Mycobacterium tuberculosis Beijing genotype strains is associated with polymorphisms in SLC11A1/NRAMP1 in Indonesian patients with tuberculosis.

Differences in host immune genes may predispose to tuberculosis caused by particular Mycobacterium tuberculosis genotypes. We examined this hypothesis in Indonesia by spoligotyping M. tuberculosis isolates recovered from 336 patients with pulmonary tuberculosis and typing the patients' SLC11A1 gene (formerly known as "NRAMP1"), which is involved in susceptibility to tuberculosis.

The effect of type 2 diabetes mellitus on the presentation and treatment response of pulmonary tuberculosis.

Background: Diabetes mellitus (DM) is a known risk factor for tuberculosis (TB), and with the increasing prevalence of type 2 DM in less developed regions, many patients with TB will have concomitant DM. Presently, little is known about the effect of DM on the clinical presentation and treatment outcome of TB.

Methods: In an urban setting in Indonesia, 737 patients with pulmonary TB were screened for DM and were followed up prospectively during TB treatment.

Cytokines related to nutritional status in patients with untreated pulmonary tuberculosis in Indonesia.

Although several studies have dealt with the patterns of cytokine production in tuberculosis, little is known about the association between nutrient deficiencies and cytokines in tuberculosis. The objective of this study was to assess the concentration of cytokines related to nutritional status during tuberculosis. In 41 untreated tuberculosis patients and matched healthy controls in an urban hospital in Indonesia, we measured: height and weight, parameters of iron, vitamin A and zinc; and cytokines concentrations in the circulation and production in whole blood cultures.

Dynamic changes in pro- and anti-inflammatory cytokine profiles and gamma interferon receptor signaling integrity correlate with tuberculosis disease activity and response to curative treatment.

Pro- and anti-inflammatory cytokines and their signaling pathways play key roles in protection from and pathogenesis of mycobacterial infection, and their balance and dynamic changes may control or predict clinical outcome. Peripheral blood cells' capacity to produce proinflammatory (tumor necrosis factor alpha [TNF-alpha], interleukin-12/23p40 [IL-12/23p40], and gamma interferon [IFN-gamma]) and anti-inflammatory (IL-10) cytokines in response to Mycobacterium tuberculosis or unrelated stimuli (lipopolysaccharide, phytohemagglutinin) was studied in 93 pulmonary tuberculosis (TB) patients and 127 healthy controls from Indonesia. Their cells' ability to respond to IFN-gamma was examined to investigate whether M.

Imported malaria in Jakarta, Indonesia: passive surveillance of returned travelers and military members postdeployment.

Background: Autochthonous malaria does not currently occur in Jakarta, the most populous city in Indonesia. Military, forestry, mining, and tourist activities draw Jakarta residents to distant parts of the archipelago with high rates of malaria. Although malaria is a reportable disease in Jakarta, little has been published.

A double-blind, placebo-controlled study of vitamin A and zinc supplementation in persons with tuberculosis in Indonesia: effects on clinical response and nutritional status.

Background: The results of cross-sectional studies indicate that micronutrient deficiencies are common in patients with tuberculosis. No published data exist on the effect of vitamin A and zinc supplementation on antituberculosis treatment.

Objective: Our goal was to investigate whether vitamin A and zinc supplementation increases the efficacy of antituberculosis treatment with respect to clinical response and nutritional status.

Decreased plasma leptin concentrations in tuberculosis patients are associated with wasting and inflammation.

Tuberculosis patients often suffer from severe weight loss, which is considered to be immunosuppressive and a major determinant of severity and outcome of disease. Because leptin is involved in weight regulation and cellular immunity, its possible role in tuberculosis-associated wasting was investigated. In an urban clinic in Indonesia, plasma leptin concentrations, indicators of adipocyte mass, appetite, C-reactive protein (CRP), tuberculin reactivity, and cytokine response were measured in tuberculosis patients and healthy controls.
