Hookworm infections (Necator americanus, Ancylostoma duodenale) are common in rural areas of tropical and subtropical countries. Human get infection from direct percutaneous invasion infective larva contaminated soil. The majority infected patients remain asymptomatic. However, iron deficiency anaemia (IDA) due to chronic blood loss is the major complication. Here we presented a case with its r...
Hookworm infection is one of the most important parasitic infections of humans, possibly outranked only by malaria as a cause of misery and suffering. An estimated 1.2 billion people are infected with hookworm in areas of rural poverty in the tropics and subtropics. Epidemiological data collected in China, Southeast Asia and Brazil indicate that, unlike other soil-transmitted helminth infection...
BACKGROUND Epidemiological evidence suggests that hookworm infection protects against asthma. However, for ethical and safety reasons, before testing this hypothesis in a clinical trial in asthma it is necessary to establish whether experimental hookworm infection might exacerbate airway responsiveness during larval lung migration. OBJECTIVE To determine whether hookworm larval migration thro...
Hookworm infection is associated with anemia, especially among children and deworming can improve anemic status; however, little information is available about the degree to which anemia improves after deworming. We chose hookworm-endemic rural areas of Thailand, Nan Province in the north, Kanchanaburi Province in the west and Nakhon Si Thammarat Province in the south, to evaluate this problem....
As part of on-going efforts to control hookworm infection, the "human hookworm vaccine initiative" has recognised blood feeding as a feasible therapeutic target for inducing immunity against hookworm infection. To this end, molecular approaches have been used to identify candidate targets, such as Necator americanus (Na) haemoglobinase aspartic protease-1 (APR-1), with immunogenicity profiled i...
deficiency anemia had a medical examination in May 2002. She was diagnosed as having anisakiasis after upper endoscopy of the antrum of the stomach, and a worm was removed. Three years later, an upper endoscopy showed several worms in the first and second portions of the duodenum, but there were no symptoms. Ten live worms were removed using standard biopsy forceps and were identified by micros...
BACKGROUND The poor correlation between allergen-specific immunoglobulin E (asIgE) and clinical signs of allergy in helminth infected populations suggests that helminth infections could protect against allergy by uncoupling asIgE from its effector mechanisms. We investigated this hypothesis in Ugandan schoolchildren coinfected with Schistosoma mansoni and hookworm. METHODS Skin prick test (SP...
Soil-transmitted helminthiases are a public health problem in rural communities. A cross-sectional study of the prevalence and distribution of Ascaris lumbricoides, Trichuris trichiura and hookworm was conducted in 281 Orang Asli children (aborigines) aged between 2 and 15 years, from 8 Orang Asli villages in Selangor, Malaysia. All the children were infected with soil-transmitted helminthes, w...
This study evaluates the economic consequences of the successful eradication of hookworm disease from the American South. The hookworm-eradication campaign (c. 1910) began soon after (i) the discovery that a variety of health problems among Southerners could be attributed to the disease and (ii) the donation by John D. Rockefeller of a substantial sum to the effort. The Rockefeller Sanitary Com...
