Infection with Soil-Transmitted Helminths Is Associated with Increased Insulin Sensitivity.

Objective: Given that helminth infections have been shown to improve insulin sensitivity in animal studies, which may be explained by beneficial effects on energy balance or by a shift in the immune system to an anti-inflammatory profile, we investigated whether soil-transmitted helminth (STH)-infected subjects are more insulin sensitive than STH-uninfected subjects.

Design: We performed a cross-sectional study on Flores island, Indonesia, an area with high prevalence of STH infections.

Methods: From 646 adults, stool samples were screened for Trichuris trichiura by microscopy and for Ascaris lumbricoides, Necator americanus, Ancylostoma duodenale, and Strongyloides stercoralis by qPCR.

Relationship between carotid intima media thickness and helminth infections on Flores Island, Indonesia.

Objective: To examine the association between helminth infections and atherosclerosis.

Background: Chronic helminth infection, which can lead to poor nutritional status and anti-inflammatory response, might protect against the development of atherosclerosis.

Methods: A cross-sectional study was performed in Flores, Indonesia, an area highly endemic for soil-transmitted helminths (STH).

Blood pressure class and carotid artery intima-media thickness in a population at the secondary epidemiological transition.

Objectives: Data relating blood pressure (BP) class to subclinical organ damage are infrequently reported in populations with a traditional 'nonwestern' lifestyle. As the relevance of BP stratification to cardiovascular prognosis has not been elucidated in these low-income countries at the second epidemiological transition, we aimed to study the effect of BP class on carotid artery intima-media thickness (IMT) in Flores Island, Indonesia.

Methods: A cross-sectional study was performed in 476 inhabitants (men/women) of Flores.

Specificity of predominant IgG4 antibodies to adult and microfilarial stages of Brugia malayi.

Human infections with filarial nematodes such as Brugia malayi are accompanied by unusually high titres of parasite-specific IgG4 antibodies. We have compared the profile of antigens recognised by filarial-specific IgG1 and IgG4 isotypes by Western blotting. Serum samples were collected from 120 subjects exposed to Brugia malayi, divided into three groups of asymptomatic amicrofilaraemic (endemic normal), microfilaraemic, and elephantiasis patients.
