Soil-transmitted helminth infections are intimately connected with poverty. Yet, there is a paucity of using socioeconomic proxies in spatially explicit risk profiling. We compiled household-level socioeconomic data pertaining to sanitation, drinking-water, education and nutrition from readily available Demographic and Health Surveys, Multiple Indicator Cluster Surveys and World Health Surveys for Cambodia and aggregated the data at village level. We conducted a systematic review to identify parasitological surveys and made every effort possible to extract, georeference and upload the data in the open source Global Neglected Tropical Diseases database. Bayesian geostatistical models were employed to spatially align the village-aggregated socioeconomic predictors with the soil-transmitted helminth infection data. The risk of soil-transmitted helminth infection was predicted at a grid of 1×1km covering Cambodia. Additionally, two separate individual-level spatial analyses were carried out, for ...
Soil-transmitted helminthiasis (STH) is a type of helminth infection (helminthiasis) caused by different species of roundworms. It is caused specifically by those worms which are transmitted through soil contaminated with faecal matter and are therefore called soil-transmitted helminths. Three types of soil-transmitted helminthiasis can be distinguished: ascariasis, hookworm infection and whipworm infection. These three types of infection are therefore caused by the large roundworm A. lumbricoides, the hookworms Necator americanus or Ancylostoma duodenale and by the whipworm Trichuris trichiura. It has become the most common parasitic disease of humans worldwide. Approximately two billion people (about a third of global population) are infected as of the latest estimate, and four billion at risk, surpassing even the all-time most prevalent parasitic disease, malaria. The largest numbers of cases occur in impoverished rural areas of Sub-Saharan Africa, Latin America, Southeast Asia, and China. ...
Despite efforts to control neglected tropical diseases (NTDs), schistosomiasis and soil-transmitted helminthiases remain widely prevalent in sub-Saharan Africa. Recent data suggest that these infections are prevalent among preschool aged children (PSAC) in poor communities. Evidence of schistosomiasis and soil-transmitted helminths (STH) infection patterns and prevalence among PSAC is essential for effective treatment and control programmes. The aim of the study was to determine the prevalence, intensity and risk factors of schistosomiasis and STH infection among PSAC in the Ingwavuma area of uMkhanyakude District, South Africa. A cross-sectional study was conducted among 1143 PSAC aged 1-5 years in 34 preschools and early childhood development (ECD) centres. Data on risk factors was collected using a semi-structured questionnaire. A Kruskal-Wallis test was used to compare the differences in infection intensity with age. Pearson Chi-square test and multivariate logistic regression were performed to

Soil-transmitted helminthiases (STH) are among the most common neglected tropical diseases (NTDs). Worldwide, it is estimated that 880 million children across 102 countries need treatment for these parasites. To eliminate morbidity from STH, the World Health Organization (WHO) recommends the periodical large-scale treatment of children in endemic areas.. Since 2010, this public health approach - also called preventive chemotherapy (PC) - has been implemented and scaled up to impressive numbers. In 2018, more than 500 million children received medicine for STH.. This progress is being made possible thanks to an innovative public-private partnership, resulting in the largest medicine donation in history and tireless efforts by program managers, teachers and volunteers who support the implementation of annual targeted treatment of children at risk of STH.. In a new paper published in Infectious Diseases of Poverty, we show how sustaining preventive chemotherapy for at least 5 consecutive years ...
Soil-transmitted helminth infections continue to plague large parts of the world with India a significant contributor to the burden of disease [2]. Despite efforts to introduce usage of pit-latrines instead of open defecation, mass deworming program and improvement in water quality and sanitation, STH infections are still prevalent. A conducive climate for its growth, rapid and unplanned urbanization, social practices of open defecation and lack of community education and sanitation are some of the factors, which impedes control of infection in India. India undertook two massive deworming programme, one starting in year 2000 where a single dose of Albendazole and DEC was administered to filarial endemic regions and another in year 2015 covering 241 million children for treatment of STH infections. Although several studies have been published from different regions of India on this topic with the earliest scientific literature dating back as far as 1923 [51], the data on STH infections remains ...
The soil-transmitted helminths (also called geohelminths) are a group of intestinal parasites belonging to the phylum Nematoda that are transmitted primarily through contaminated soil. They are so called because they have a direct life cycle which requires no intermediate hosts or vectors, and the parasitic infection occurs through faecal contamination of soil, foodstuffs and water supplies. The adult forms are essentially parasites of humans, causing soil-transmitted helminthiasis (STH), but also infect domesticated mammals. The juveniles are the infective forms and they undergo tissue-migratory stages during which they invade vital organs such as lungs and liver. Thus the disease manifestations can be both local and systemic. The geohelminths together present an enormous infection burden on humanity, amounting to 135,000 deaths every year, and persistent infection of more than two billion people. Soil-transmitted helminths are typically from the following families of nematodes, ...
Rifampicin antibiotic is a new anti-wolbachia drug that was found to change the therapeutic approach for parasitic helminth diseases.
Intestinal helminth infections are the most prevalent neglected tropical diseases, predominantly affecting rural and marginalised populations. The mainstay of diagnosis is the microscopic examination of faecal samples to detect parasites in the form of eggs, larvae and cysts. In an effort to improve the standard of care, the comparative accuracy in detecting helminth infections of the hitherto used formalin-based concentration method (FC) was compared to a previously developed formalin ethyl-acetate-based concentration technique (FECT), prior to the systematic deployment of the latter at a research and humanitarian unit operating on the Thailand-Myanmar border. A total of 693 faecal samples were available for the comparison of the two diagnostic methods. The FECT was superior in detecting hookworm, Trichuris trichiura and small liver flukes. Interestingly, there was no significant difference for Ascaris lumbricoides, possibly due to the high observed egg density. Despite the minor increase in material
Following a recent Cochrane Systematic Review on deworming of school children against soil-transmitted helminthiasis, WHOs Strategic and Technical Advisory Group for Neglected Tropical Diseases (STAG-NTD) has issued a statement regarding the same. The STAG-NTD has reviewed the evidence (including the Cochrane Review) and states that it continues to endorse WHOs recommendation for mass deworming in areas…
In the acute phase of helminth infections are the main manifestations are due to toxic-allergic effect of parasitic worms on the body. In patients with marked fever, skin rash, muscle pain, lymphadenopathy. Often develops abdominal syndrome (dyspepsia, abdominal pain), pulmonary syndrome (dry cough, bronchospasm, shortness of breath), hepatolienal syndrome (enlarged liver and spleen), asthenovegetative syndrome (apathy, fatigue, sleep disturbances, irritability).. In the chronic phase of helminthiasis is dominated by organ-specific lesions caused mainly mechanical traumatization of the place of parasitism of helminths. So, in determining the course of intestinal helminths are dyspepsia and abdominal pain. The malabsorption in the intestine is accompanied by the polyhypovitaminosis, progressive weight loss. Frequent companion of intestinal helminth infections is iron deficiency anemia. When a massive parasitic infestation may rectal prolapse, hemorrhagic colitis, intestinal obstruction.. In the ...
Diagnosis of soil-transmitted helminths (STHs) in developing countries is commonly based on microscopic detection of eggs in stool samples, using the Kato-Katz (KK) method, which has a poor sensitivity for detecting light intensity infections. We compared the performance of the KK method and real-time PCR in the framework of a randomized trial, which evaluated four novel treatments against Trichuris trichiura and concomitant STH infections. Two stool samples obtained from 320 participants were examined at baseline and follow-up with quadruplicate KK and PCR analyses of one of the two samples using

MARTINEZ-BARBABOSA, Ignacio et al. Frequency of geohelminths in pet dogs from seven municipalities of Mexico City. Vet. Méx [online]. 2011, vol.42, n.1, pp.83-91. ISSN 0301-5092.. The aim of this study was to analyze the degree of infection by geohelminths in pet dogs in seven municipalities of Mexico City, together with some risk factors for human health. Two hundred samples of canine faeces were analyzed using the Stoll method. A questionnaire was applied to their owners to obtain epidemiological data. The statistical analysis was carried out using chi-square to determine the relationship between the infection and selected variables, taking P = 0.10 as the significant value. The prevalence of geohelminths was 20% (40/200). T. canis 14% and A. caninum 7.5%. All the infections were slight. When the presence of the infection was correlated with the other variables, the following results were obtained: type of dwelling (P = 0.016), presence or not of a garden (P = 0.019), sleeping place of the ...
In this study, we took a multiomic approach toward investigating the effects of coinfection with soil-transmitted helminths and P. vivax. To our surprise, we found that the gut microbiota communities had a stronger association with malaria infection than with STH infections. We had previously reported, in both cross-sectional (20) and longitudinal (21) studies on the Orang Asli in Malaysia, that T. trichiura infection impacted microbial diversity and the composition of the microbiota in infected individuals. In contrast, the current study found that the microbiota of uninfected and STH-infected individuals are not significantly different (Fig. 4A; see also Fig. S5 in the supplemental material). This suggests that the environment in which the microbiota and STH exist (all the other cofactors, such as the diet, age, lifestyle, and other previous and current infections of the human host) may determine whether or not STH affect the gut microbiota. This could explain why the effects of STH on the gut ...
This volume covers research on the interaction of major helminth parasites with the immune system. The main focus of the e-book is the ability of helminths to subvert host immune responses, on the one hand. On the other hand, the immunological armamentarium of the host against invading parasites is described also in the light of new findings on innate and adaptive immunity. These include the discovery of a new category of lymphocytes, innate lymphoid cells, and the role of T helper cels such as Th1, Th2 and Th3 cells, T regulatory (Treg) and Th17 cells in helminth diseases and inflammation. The balance between these two T cell subsets during the various stages of helminth diseases is also discussed. The book concludes with a review of new therapeutic approaches to combat helminth parasites (biotherapy, vaccines and natural products). Immunity to Helminths and Novel Therapeutic Approaches provides updated information for medical students, clinicians and researchers in the fields of parasitology, ...

Soil-transmitted helminthiasis is one of 17 neglected tropical diseases, a grouping that also includes dengue and chikungunya, rabies, and leprosy. These infectious diseases largely affect the worlds most impoverished people, causing a high human and economic toll through chronic disability.. As their name suggests, they have historically received little global interest or research funding when compared to the big three diseases on the global health agenda: HIV/AIDS, tuberculosis and malaria.. The good news is that neglected tropical diseases have been rising to prominence since the 2012 London Declaration on Neglected Tropical Diseases. This large public-private partnership is committed to eliminating or controlling ten preventable neglected tropical diseases by 2020, and has attracted substantial investment from government and philanthropic sources.. ...

Background: The impact of helminth infection on the host immune response to tuberculosis (TB) has been characterized in experimental models but less so in the clinical setting. The objective of this study was to investigate the impact of deworming on the clinical outcome and cell mediated immune response in active TB.. Methods: Newly diagnosed pulmonary TB patients in Gondar, Ethiopia were examined for helminth infection. Helminth-positive TB patients (W+/TB) were randomized to albendazole (400mg X III per os) or placebo. The primary outcome was change in TB-score after 2 months, and secondary outcomes were sputum smear conversion at the 2nd month, and changes in chest x-ray pattern, CD4+ T-cell count, eosinophil count, IgE-levels and immunological responses after 3 months. In a subset of W+/TB, W-/TB patients and healthy controls, flow cytometry and ELISPOT assays were used to characterize the regulatory T-cell population (Tregs) and the frequency of PPD- stimulated IFN-γ, IL-5 and IL-10 ...

Kato-Katz is a widely used method for the diagnosis of soil-transmitted helminth infection. Fecal samples cannot be preserved, and hence, should be processed on the day of collection and examined under a microscope within 60 min of slide preparation. Mini-FLOTAC is a technique that allows examining fixed fecal samples. We assessed the performance of Mini-FLOTAC using formalin-fixed stool samples compared to Kato-Katz and determined the dynamics of prevalence and intensity estimates of soil-transmitted helminth infection over a 31-day time period.; The study was carried out in late 2013 on Pemba Island, Tanzania. Forty-one children were enrolled and stool samples were subjected on the day of collection to a single Kato-Katz thick smear and Mini-FLOTAC examination; 12 aliquots of stool were fixed in 5% formalin and subsequently examined by Mini-FLOTAC up to 31 days after collection.; The combined results from Kato-Katz and Mini-FLOTAC revealed that 100% of children were positive for Trichuris ...

This study aimed to assess the effectiveness of a rural sanitation intervention, within the context of the Government of Indias Total Sanitation Campaign, to prevent diarrhoea, soil-transmitted helminth infection, and child malnutrition. It is based on a cluster-randomised controlled trial between May 20, 2010, and December 22, 2013, in 100 rural villages in Odisha, India.
BACKGROUND: In the first part of this study, we investigated the prevalence and associated key factors of soil-transmitted helminth (STH) infections among Orang Asli children in rural Malaysia; an alarming high prevalence and five key factors significantly associated with infections were reported. Part 2 of this study aims to evaluate the knowledge, attitude and practices (KAP) on STH infections among Orang Asli in Peninsular Malaysia.. METHODS: A cross-sectional study was carried out among 215 households from 13 villages in Lipis district, Pahang, Malaysia. Demographic and socioeconomic information of the participants and their KAP on STH were collected by using a pre-tested questionnaire.. RESULTS: Overall, 61.4% of the participants had prior knowledge about intestinal helminths with a lack of knowledge on the transmission (28.8%), signs and symptoms (29.3%) as well as the prevention (16.3%). Half of the respondents considered STH as harmful, while their practices to prevent infections were ...
Helminths (/ˈhɛlmɪnθs/), also commonly known as parasitic worms, are large multicellular organisms, which when mature can generally be seen with the naked eye. They are often referred to as intestinal worms even though not all helminths reside in the intestines; for example schistosomes are not intestinal worms, but rather reside in blood vessels.. There is no clear consensus on the taxonomy of helminths; it is more of a commonly used term to describe certain worms with superficial similarities. These are flatworms (platyhelminthes), namely cestodes (tapeworms) and trematodes (flukes), and roundworms or nemathelminths (nematodes) - both of these are parasitic worm types - and the annelida, which are not parasitic or at the most ectoparasites like the leeches.[1]. Many, but not all, of the worms referred to as helminths belong to the group of intestinal parasites. An infection by a helminth is known as helminthiasis, soil-transmitted helminthiasis, helminth infection or intestinal worm ...
The geographic distribution of helminth infection and tuberculosis (TB) overlap substantially. Experimental animal models and limited data from humans have shown that intestinal helminths could subvert the host immune response towards a T-helper 2 (Th2)-type immune response and an increased regulatory T-cell activity (Tregs). This in turn affects the hosts ability to mount an effective Th1 immune-mediated protection against Mycobacterium tuberculosis. However, evidence for this hypothesis in the human setting from helminth infected TB patients is limited. This thesis primarily focuses on the immunological and clinical impact of helminth infection on pulmonary TB. The kinetics of the Quantiferon-Gold (QFN) assay, which measures IFN-³ response to TB-specific antigens in whole blood was assessed and showed a modest decline during TB treatment to the level observed for healthy blood donors. We further assessed another clinical monitoring tool, the-TB-score, composed of clinical signs and symptoms ...
Abstract. Soil-transmitted helminths (STHs) are controlled by regular mass drug administration. Current practice targets school-age children (SAC) preferentially over pre-school age children (PSAC) and treats large areas as having uniform prevalence. We assessed infection prevalence in SAC and PSAC and spatial infection heterogeneity, using a cross-sectional study in two slum villages in Kibera, Nairobi. Nairobi has low reported STH prevalence. The SAC and PSAC were randomly selected from the International Emerging Infections Program's surveillance platform. Data included residence location and three stools tested by Kato-Katz for STHs. Prevalences among 692 analyzable children were any STH: PSAC 40.5%, SAC 40.7%; Ascaris: PSAC 24.1%, SAC 22.7%; Trichuris: PSAC 24.0%, SAC 28.8%; hookworm < 0.1%. The STH infection prevalence ranged from 22% to 71% between sub-village sectors. The PSAC have similar STH prevalences to SAC and should receive deworming. Small areas can contain heterogeneous
In this study altered immune response as measured by total serum IgE level among symptomatic HIV infected patients, asymptomatic HIV positive individuals and healthy controls with and without helminths co-infection and the impact of deworming and/or ART on these immune activation was assessed within defined groups of population from tropical settings of Ethiopia where both HIV and helminths infections are common. Consistent with the earlier suggestions [25-27] that Africans generally present with elevated total serum IgE levels and our previous observations [14-16], patients in this study also showed a high total serum IgE level as shown by more than three-folds of the total IgE above the reference ranges irrespective of HIV and helminths co-infections. The highly significant correlation between helminth egg intensity and serum IgE level may partly explain the elevated total serum IgE levels observed in sub-Saharan regions, where heavy helminthic infections are widespread [14-16, 25-27]. It ...
Background: On the basis of immunological considerations and in vitro trials on co-infections there is strong reason to suspect a detrimental effect of helminth infection on the course of HIV. The immunological answer very efficiently evoked by helminth infection is aimed at hijacking and suppressing the immune system in order to suit the requirements of the specific helminth. This permits helminths to cause chronic infection, often persisting over years and allowing some infecting worms to grow to several centimetres of length within their host. However, this immune modulation also affects non-related antigens (for example HIV) which would actually require a different line of immunological action.. Some clinical trials have been able to confirm this detrimental effect of helminths on HIV infection, while other trials failed to do so. A recent Cochrane review on clinical trials with HIV and helminth co-infection found an overall slight reduction of HIV viral load if helminth infection was ...

In the developing world hundreds of millions of people suffer from intestinal parasitic worms (helminths) and intestinal protozoon infections (e.g. amoebiasis). These are often referred to neglected tropical diseases. This worm like organisms feed on their host, taking the nutrition and causing weakness and disease. More than 1 billion people are infected with soil-transmitted helminths, schistosomes and intestinal protozoa and the annual global burden might be as high as that owing to malaria or tuberculosis. This can cause undernourishment, dysentery (infection of the intestines) and diarrhea. It has been shown that parasitic infections in childhood can interfere with cognitive development (mental) and can have negative effects in adulthood. The global strategy to control helminthiasis is preventive chemotherapy, which is the regular administration of anthelminthic drugs (medication that works to treat parasitic worms) to at-risk populations. However, re-infection can occur due to unclear ...
Author Summary Schistosomiasis is a parasitic disease infecting over 200 million people. It remains a major public health concern despite treatment of over 120 million people in sub-Saharan Africa alone. Accurate diagnostic methods are essential for monitoring drug efficacy and long-term control program success. The World Health Organization recommends two Kato-Katz thick smears (Kato-Katzs) from a single stool for Schistosoma mansoni diagnosis to map prevalence and areas for control interventions. Although highly specific, Kato-Katzs are thought to be insensitive at low egg counts. The recently refined urine point-of-care circulating cathodic antigen test (POC-CCA) has been proposed as a diagnostic alternative for mapping areas for interventions, and potentially for assessing drug efficacy. Over three years we assessed the accuracy of six Kato-Katzs and a single POC-CCA in detecting infections in Ugandan primary-school children at 11 time points with repeated praziquantel treatments. Our results
LONDON - Chronic diarrhoea could be treated using parasitic worms, according to a new study.. Researchers from the New York University Langone Medical Center in a study of monkeys found that the treatment restores gut bacteria to a healthy state. Other work in mice has already suggested conditions such as ulcerative colitis could be treated in this way, the BBC News reported. Inflammatory bowel diseases, like colitis, are often fuelled by a wrongly targeted response by the immune system to gut bacteria.. Such diseases are more common in developed countries and scientists suggest this is because people in developing countries have more exposure to parasitic worm (helminth) infections and therefore have a natural protection that has evolved as people and worms learnt to co-exist. Recent studies have used parasitic worms to successfully treat inflammatory bowel disease in humans, but it is unclear exactly how they do this. The latest study looked at monkeys because young macaques kept in captivity ...

As an alternative strategy, we have focused on the use of defined parasitic worm products and recently taken this one step further by designing drug-like small molecule analogues of one such product, ES-62, which is anti-inflammatory by virtue of covalently attached phosphorylcholine moieties. Previously, we have shown that ES-62 mimics are efficacious in protecting against disease in mouse models of rheumatoid arthritis, systemic ...

Geohelminth infections are highly prevalent infectious diseases of childhood in many regions of the Tropics, and are associated with significant morbidity especially among pre-school and school-age children. There is growing concern that geohelminth infections, particularly exposures occurring during early life in utero through maternal infections or during infancy, may affect vaccine immunogenicity in populations among whom these infections are endemic. Further, the low prevalence of allergic disease in the rural Tropics has been attributed to the immune modulatory effects of these infections and there is concern that widespread use of anthelmintic treatment in high-risk groups may be associated with an increase in the prevalence of allergic diseases. Because the most widely used vaccines are administered during the first year of life and the antecedents of allergic disease are considered to occur in early childhood, the present study has been designed to investigate the impact of early exposures to
This paper reports the prevalence and intensity of soil-transmitted helminth (STH) infections measured in Zimbabwe before and after a control intervention based on annual deworming of school-age children (SAC) conducted from 2012 to 2018. In 2010, epidemiological data were collected from 13 195 SAC in 255 randomly selected schools in all districts nationwide using, as diagnostic methods, the Kato-Katz and the formal ether stool concentration technique. At follow up, conducted in 2017, only Kato-Katz was performed; specimens were collected from 13 352 children in 336 schools. The data were evaluated using a geospatial approach. The national prevalence of STH infection in SAC was estimated at 5.8% at baseline, with 0.8% of infections of moderate and heavy intensity. Preventive chemotherapy (PC) targeted all 2.5 million children of school age enrolled in Zimbabwe, with coverage ranging from 49% to 85%. At follow up, national prevalence of STH in SAC was estimated at 0.8%; infections of moderate and ...
Funding agencies are dedicating substantial resources to tackle helminth infections. Reliable maps of the distribution of helminth infection can assist these efforts by targeting control resources to areas of greatest need. The ability to define the distribution of infection at regional, national and subnational levels has been enhanced greatly by the increased availability of good quality survey data and the use of model-based geostatistics (MBG), enabling spatial prediction in unsampled locations. A major advantage of MBG risk mapping approaches is that they provide a flexible statistical platform for handling and representing different sources of uncertainty, providing plausible and robust information on the spatial distribution of infections to inform the design and implementation of control programmes. Focussing on schistosomiasis and soil-transmitted helminthiasis, with additional examples for lymphatic filariasis and onchocerciasis, we review the progress made to date with the application of MBG
Helminths, including nematodes, cestodes and trematodes, are complex parasitic organisms that infect at least one billion people globally living in extreme poverty. Helminthic infections are associated with severe morbidity particularly in young children who often harbor the highest burden of disease. While each helminth species completes a distinct life cycle within the host, several helminths incite significant lung disease. This impact on the lungs occurs either directly from larval migration and host immune activation or indirectly from a systemic inflammatory immune response. The impact of helminths on the pulmonary immune response involves a sophisticated orchestration and activation of the host innate and adaptive immune cells. The consequences of activating pulmonary host immune responses are variable with several helminthic infections leading to severe, pulmonary compromise while others providing immune tolerance and protection against the development of pulmonary diseases.

(Medical Xpress)-Doctor Joel Weinstock, a parasitologist at Tufts Medical Center in a commentary piece published in the journal Nature, describes work that he and colleagues have been involved in that focuses on studying the possibility of introducing parasitic worms into the guts of patients suffering from autoimmune diseases such as Crohns disease. The thinking he says, is that modern hygienic lifestyles may be contributing to such diseases and that reintroducing parasitic worms and perhaps certain bacteria into the gut may restore a natural balance in the gut and relieve patients of such symptoms as chronic diarrhea, bleeding and infections.
We recently demonstrated better outcomes in helminth-infected multiple sclerosis (MS) patients, compared with uninfected ones. The present study evaluates the role of TLR2 and retinoic acid (RA) in parasite-driven protection in MS patients. RA serum levels were significantly higher in helminth-infected MS patients than in uninfected MS subjects or healthy controls. Genes involved in RA biosynthesis and metabolism, such as Adh1 and Raldh2, as well as RA receptors and IL-10, were induced in dendritic cells (DCs) via TLR2-dependent ERK signaling. This programmed DCs to induce FOXP3+ T regulatory cells and suppressed production of proinflammatory cytokines (IL-6, IL-12, IL-23, and TNF-α) via induction of suppressor of cytokine signaling 3 (SOCS3), an effect mediated by soluble egg Ag (SEA) obtained from Schistosoma mansoni, and by RA. SEA-activated DCs also inhibited IL-17 and IFN-γ production through autoreactive T cells. These inhibitory effects were abrogated when SOCS3 gene expression was ...
Abstract Background The convergent distribution of the Human Immunodeficiency Virus (HIV) and helminth infections has led to the suggestion that infection with helminths exacerbates the HIV epidemic in developing countries. In South Africa, it is estimated that 57% of the population lives in poverty and carries the highest burden of both HIV and helmith infections, however, the disease interactions are under-researched. Methods We employed both coproscopy and Ascaris lumbricoides-specific serum IgE to increase diagnostic sensitivity and to distinguish between different helminth infection phenotypes and their effects on immune responses in HIV co-infected individuals. Coproscopy was done by formol ether and Kato Katz methods. HIV positive and negative adults were stratified according to the presence or absence of A. lumbricoides and/or Trichuris trichuria eggs with or without elevated Ascaris IgE. Lymphocyte subsets were phenotyped by flow cytometry. Viral loads, serum total IgE and eosinophils ...

Monday, February 17, 2014. Nigerian health officials partnering with international experts have embarked on a national programme to map Neglected Tropical Diseases (NTDs) by analysing data obtained from 14 of the countrys 36 states.. According to Nigerias Federal Ministry of Health, the country and the Democratic Republic of Congo, Ethiopia and Tanzania - contribute to more than 50 per cent of the NTDs burden in Africa, partly because they have climatic conditions that favour the diseases.. Experts say common NTDs in Nigeria include schistosomiasis, soil-transmitted helminth infections, trachoma, onchocerciasis and lymphatic filariasis.. ...
Preventive chemotherapy and transmission control (PCT) is the main strategy for control of onchocerciasis, lymphatic filariasis, schistosomiasis, soil-transmitted helminthiasis and trachoma. The strategy involves regular provision of preventive treatment (in the form of mass drug administration (MDA) campaigns) to entire populations or targeted risk groups (e.g. schoolchildren). This strategy reduces disease progression in treated individuals and prevents transmission of infection to others. Mass drug administration (MDA) programmes are rapidly expanding, although important questions remain. For example, will the planned MDA programmes be sufficient to achieve elimination in all epidemiological settings? To what extent is successful elimination jeopardized by low coverage and systematic non-adherence? When, and on the basis of what criteria can MDA be safely interrupted? Each of the modelling analyses highlight the importance of groups who systematically, or semi-systematically do not access MDA ...

Pets that are infested with a small number of worms may show no symptoms at all.. Diagnosis and Treatment of Worms in Cats and Dogs. Deworming is a simple procedure and relatively inexpensive. If worms are diagnosed via a stool sample, a deworming medication can be administered to eliminate them (such medications often require more than one application). Depending on the type of worms, medications are available as pills, liquids, pastes, chewables, topical treatments, and injectables.. If pets are treated at the first sign of worm infection, prognosis is good. Even very young animals are unlikely to die unless treatment is delayed until an infection is severe.. How to Prevent Intestinal Worm Infection in Cats, Dogs, and Humans. To reduce the risk of pets and people being infected with intestinal worms:. ...

Parasitic worms in humans are often associated with travel, but you can also get them at home. These organisms live in and feed off a living host, like a human. They arent always visible to the naked eye but are treatable. Heres what you should know about transmission, treatment, and how to avoid being a host.
Parasitic worms may be useful in treating lung disease and healing wounds, according to a study published online today (Jan.15) in Nature Medicine.
BACKGROUND: Reliable and updated maps of helminth (worm) infection distributions are essential to target control strategies to those populations in greatest need. Although many surveys have been conducted in endemic countries, the data are rarely available in a form that is accessible to policy makers and the managers of public health programmes. This is especially true in sub-Saharan Africa, where empirical data are seldom in the public domain. In an attempt to address the paucity of geographical information on helminth risk, this article describes the development of an updated global atlas of human helminth infection, showing the example of East Africa. METHODS: Empirical, cross-sectional estimates of infection prevalence conducted since 1980 were identified using electronic and manual search strategies of published and unpublished sources. A number of inclusion criteria were imposed for identified information, which was extracted into a standardized database. Details of survey population, ...

Routine deworming during antenatal care decreases risk of neonatal mortality and low birthweight: a retrospective cohort of survey data (to hyperlink) authored by Syracuse University, the World Health Organization (WHO) and SUNY Upstate is published in the journal, PLoS Neglected Tropical Diseases.. The researchers matched births on the probability of receiving deworming during pregnancy. They then modelled birth outcomes with the matched group to estimate the effect of deworming during antenatal care after accounting for various risk factors. They also tested for effect modification of soil-transmitted helminth prevalence on the impact of deworming during antenatal care.. Intestinal worms impact the health of women and girls of reproductive age and this study supports the fact that treating pregnant women can be beneficial, said Dr Antonio Montresor, Medical Officer, WHO Department of Control of Neglected Tropical Diseases.
