The constant presence of diseases or infectious agents within a given geographic area or population group. It may also refer to the usual prevalence of a given disease with such area or group. It includes holoendemic and hyperendemic diseases. A holoendemic disease is one for which a high prevalent level of infection begins early in life and affects most of the child population, leading to a state of equilibrium such that the adult population shows evidence of the disease much less commonly than do children (malaria in many communities is a holoendemic disease). A hyperendemic disease is one that is constantly present at a high incidence and/or prevalence rate and affects all groups equally. (Last, A Dictionary of Epidemiology, 3d ed, p53, 78, 80)

Natural history of papillary lesions of the urinary bladder in schistosomiasis. (1/895)

Variable epithelial hyperplasia was observed in urinary bladder of nine capuchin monkeys (Cebus apella) when examined at cystotomy 94 to 164 weeks after infection with Schistosoma haematobium. These hosts were followed for 24 to 136 weeks postcystotomy to determine the status of bladder lesions in relation to duration of infection and to ascertain whether lesion samples removed at cystotomy reestablished themselves in autologous and heterologous transfers. There was involution of urothelial hyperplasia in eight of nine animals and no evidence for establishment of transplanted bladder lesions.  (+info)

Candidate parasitic diseases. (2/895)

This paper discusses five parasitic diseases: American trypanosomiasis (Chagas disease), dracunculiasis, lymphatic filariasis, onchocerciasis and schistosomiasis. The available technology and health infrastructures in developing countries permit the eradication of dracunculiasis and the elimination of lymphatic filariasis due to Wuchereria bancrofti. Blindness due to onchocerciasis and transmission of this disease will be prevented in eleven West African countries; transmission of Chagas disease will be interrupted. A well-coordinated international effort is required to ensure that scarce resources are not wasted, efforts are not duplicated, and planned national programmes are well supported.  (+info)

Double-blind placebo-controlled study of concurrent administration of albendazole and praziquantel in schoolchildren with schistosomiasis and geohelminths. (3/895)

A double-blind placebo-controlled study of the concurrent administration of albendazole and praziquantel was conducted in>1500 children with high prevalences of geohelminths and schistosomiasis. The study sites were in China and the Philippines, including 2 strains of Schistosoma japonicum, and 2 different regions of Kenya, 1 each with endemic Schistosoma mansoni or Schistosoma haematobium. Neither medication affected the cure rate of the other. There was no difference between the side effect rate from albendazole or the double placebo. Praziquantel-treated children had more nausea, abdominal pain, and headache but these side effects were statistically more common in children with schistosomiasis, suggesting a strong influence of dying parasites. The subjects were followed for 6 months for changes in infection status, growth parameters, hemoglobin, and schistosomiasis morbidity. In all 4 sites, a significant 6-month increase in serum hemoglobin was observed in children who received praziquantel, strongly supporting population-based mass treatment.  (+info)

Age-specific decrease in seroprevalence of schistosomiasis in Puerto Rico. (4/895)

In our previous work, we reported the first systematic, island-wide, serologic survey for schistosomiasis in Puerto Rico in 40 years. In that study, approximately 3,000 serum samples from the 76 municipalities comprising the island of Puerto Rico were tested for the detection of antibodies to S. mansoni microsomal antigens by the Falcon assay screening test-enzyme-linked immunosorbent assay (FAST-ELISA) and those positive were confirmed by an enzyme-linked immunoelectrotransfer blot (EITB). The highest EITB positivity was found in 17 municipalities, which comprised 48% of all seropositive samples. An additional finding was that 10% of the 215 EITB-positive samples were from individuals 25 years or younger and were for the most part of residents from the high seroprevalence areas. Thus, for this study we focused on 766 individuals 25 years of age or younger (45.5% males and 54.4% females), two-thirds of which were from 10 municipalities with the highest EITB seropositivity, and one-third from the 10 municipalities with the lowest EITB seropositivity found in our previous study. Of all samples, the results showed an overall FAST-ELISA positivity of 11.6%, with males similar to females (12.6 versus 10.7%, respectively). Confirmation by EITB was only 1.8%, with a males three-fold higher than females (3% versus 0.7%). When seropositivity was measured by age in five-year increments, a clear age-specific decrease in seropositivity was observed. Thus, by FAST-ELISA, 16.7% of the 21-25-year-old age group was positive, decreasing to 14.6%, 9.9%, 7.9%, and 9.3% in the 16-20-, 11-15-, 6-10-, and 1-5-year-old age groups, respectively. Confirmatory EITB showed even more impressive results: 4.7%, 2.6%, 1.2%, 0.7%, and 0% in the same age brackets. With regard to the high prevalence municipalities, only four of 10 (11 of 228 = 4.8%) had confirmatory EITB-positive samples and most were from municipalities of the Rio Grande de Loiza River basin and tributaries. The male to female positivity ratio was 4:1. Of the low prevalence municipalities, only single positive cases (by EITB) were found in three disperse municipalities. These results support the concept that there has been little transmission of S. mansoni in Puerto Rico during the first half of the 1990s and confirms anecdotal comments of local physicians who have seen virtually no new infections during the past three years. This makes the documentation of eradication of schistosomiasis from Puerto Rico feasible, a goal that should be set as being before the 100th anniversary of its discovery on the island by Isaac Gonzalez-Martinez in 1904.  (+info)

Full results of the genome-wide scan which localises a locus controlling the intensity of infection by Schistosoma mansoni on chromosome 5q31-q33. (5/895)

Three hundred million individuals are at risk of infection by schistosomes, and thousands die each year of severe hepatic disease. Previous studies have shown that the intensity of infection by Schistosoma mansoni in a Brazilian population is controlled by a major gene, denoted as SM1. We report here the full results of a genome-wide search that was performed on this population to localise SM1. Two hundred and forty-six microsatellites were used for the primary map, and only one region in 5q31-q33 provided significant evidence of linkage. SM1 was subsequently mapped to this region, which contains several genes encoding cytokines or cytokine receptors which are involved in protection against schistosomes. Three additional regions, 1p22.2, 7q36 and 21q22-22-qter, yielded promising, although not significant, lod-score values. These regions contain candidate genes encoding cytokines or molecules relevant to anti-schistosome immunity.  (+info)

Cytotoxicity of human and baboon mononuclear phagocytes against schistosomula in vitro: induction by immune complexes containing IgE and Schistosoma mansoni antigens. (6/895)

Normal human blood monocytes, pre-incubated at 37 degrees C with sera from patients infected with Schistosoma mansoni, strongly adhered to S. mansoni schistosomula in vitro, whereas no significant adherence was induced by sera from uninfected individuals. Comparable adherence occurred with normal baboon blood monocytes or peritoneal macrophages when these cells were incubated with sera from S. mansoni-infected baboons. Adherence of macrophages to schistosomula was associated with damage to the larvae, as estimated by a 51Cr release technique. Neither adherence nor cytotoxicity was induced by pre-incubation of the schistosomula, instead of the monocytes, with immune serum. The relevant factor in immune serum was heat-labile, but was not a complement component. Absorption and ultracentrifugation experiments showed that immune complexes, containing S. mansoni-specific IgE antibody and soluble parasite antigens, produced monocyte or macrophage adherence and cytotoxicity. Similar observations have been reported previously in the rat model. Since the production of large amounts of IgE is a predominant feature of schistosome infections in man and experimental animals, it is possible that this new mode of mononuclear phagocyte activation could act as an immune effector mechanism against S. mansoni.  (+info)

Controlling schistosomiasis: the cost-effectiveness of alternative delivery strategies. (7/895)

Sustainable schistosomiasis control cannot be based on large-scale vertical treatment strategies in most endemic countries, yet little is known about the costs and effectiveness of more affordable options. This paper presents calculations of the cost-effectiveness of two forms of chemotherapy targeted at school-children and compares them with chemotherapy integrated into the routine activities of the primary health care system. The focus is on Schistosoma haematobium. Economic and epidemiological data are taken from the Kilombero District of Tanzania. The paper also develops a framework for possible use by programme managers to evaluate similar options in different epidemiological settings. The results suggest that all three options are more affordable and sustainable than the vertical strategies for which cost data are available in the literature. Passive testing and treatment through primary health facilities proved the most effective and cost-effective option given the screening and compliance rates observed in the Kilombero District.  (+info)

Eradication of schistosomiasis in Guangxi, China. Part 3. Community diagnosis of the worst-affected areas and maintenance strategies for the future. (8/895)

Reported are the results of a community-based assessment of maintenance of schistosomiasis eradication in Guangxi, a large autonomous region of China with a population of 44 million. Eradication of the disease was achieved in 1989 in Guangxi but maintenance costs are rising. We focused on three counties that had the most intense transmission in the past: Binyang, Jingxi, and Yishan. Four instruments were used: in-depth interviews, focus group discussions, a knowledge, attitudes and practices survey, and subsequent community feedback. In the past, schistosomiasis had serious consequences in Guangxi, decreasing work capacity and restricting marriage and occupational mobility. Since its eradication there have been clear benefits in terms of increased agricultural output and improved farming conditions. Personal habits and traditional manual farming activities in Guangxi would continue to expose a large proportion of the population to environmental risk if the disease were to return. Ignorance about control programme achievements is increasing and is related to youth and inexperience. There was a universal desire in the study counties for more local education about the history of the programme and about the risk of schistosomiasis returning. Snail surveillance is considered important, but people are not willing to volunteer for such work. Our study methods were novel for Guangxi and community feedback was helpful. Snail checking procedures have been modified to make them more efficient and no snails have been found since 1992. The animal and human stool examinations have ceased and vigilance now concentrates on snails and children (skin tests). The long-term strategy is to make the population invulnerable to future schistosomiasis transmission if the snail vectors return. This means continuing education and making the former endemic counties a high priority for water and sanitation improvements.  (+info)

Intestinal schistosomiasis, caused by Schistosoma japonicum, S. mekongi, mansoni, and S. intercalatum, can lead to serious complications ofthe liver and spleen. Urinary schistosomiasis is caused by S. haematobium.. It is difficult to know how many individuals die of schistosomiasis each yearbecause death certificates and patient records seldom identify schistosomiasis as the primary cause of death. Mortality estimates vary related to the type of schistosome infection but is generally low, for example, 2.4 of 100,000die each year from infection with S. mansoni.. All five species are contracted in the same way, through direct contact withfresh water infested with the free-living form of the parasite known as cercariae. The building of dams, irrigation systems, and reservoirs, and the movements of refugee groups introduce and spread schistosomiasis.. Eggs are excreted in human urine and feces and, in areas with poor sanitation, contaminate freshwater sources. The eggs break open to release a form ...
Summary 1. In the vicinity of Jaffa, Palestine, about the River Auja and its tributaries, there exists an endemic focus of vesical bilharziasis of not insignificant range. Progress in intensive farming will make it of still greater importance. 2. Contrary to prevailing opinion, the diagnosis of light cases of vesical bilharziasis by means of microscopical urine tests, frequently presents serious difficulties. In many cases, also eosinophilia fails as a positive test. In those cases, complement fixation (according to Fairley) seems to acquire particular significance. 3. In no case did subcutaneous application of emetine lead to permanent cure. On the other hand intravenous application of antimony tartrate (Christopherson's method) produced not a single failure. Sumario 1. En la vecindad de Jaffa, Palestina y en los alrededores del río Auja y sus tributarios, existe un foco endémico de bilharziosis vesical cuyo alcance es de importancia. El cultivo intenso del terreno le dará mayor importancia
The present study was conducted to analyze the alterations affecting cyclins D1, E, and A in bilharzial bladder cancer and to assess their potential clinical significance. A total of 125 cases were examined. Histopathological subtypes included 68 squamous cell carcinomas, 55 transitional cell carcinomas, and 2 adenocarcinomas. Immunohistochemical analyses were performed using a panel of well-characterized antibodies. The results were correlated with proliferative index, as assessed by Ki67 antigen expression. The cyclin D1-positive phenotype, defined as the identification of positive immunoreactivity in the nuclei of ,/=20% of tumor cells, was found in 33 of 107 (31%) evaluable cases. A significant association was observed between the cyclin D1-positive phenotype and deep muscle invasion (P = 0.02), high tumor grade (P = 0.02), and Ki67 high proliferative index (P = 0.03). The cyclin E-positive phenotype, defined as per cyclin D1, was found in 79 of 106 (75%) evaluable cases. The cyclin ...
Introduction. Epidemiology. Schistosomiasis (also known as bilharzia) is the second most important tropical disease after malaria, in terms of public health impact.1 Over 800 million people are at the risk of acquiring schistosomiasis in 76 endemic countries, with 46 of these countries in Africa.2,3 Approximately 207 million people worldwide are infected with schistosomiasis4 and 85% of the estimated number of infections are in the less developed areas of sub-Saharan Africa. Worldwide, Schistosoma haematobium causes more than half of the schistosomiasis infections, that is, approximately 112 million infections.4 S. haematobium and S. mansoni are responsible for about 280 000 deaths annually.4 In South Africa, more than 4 million people are estimated to be infected with schistosomiasis.4 The endemic areas in South Africa are in the north and the east, covering about a quarter of the country.5 The most common species in South Africa is S. haematobium . School-aged children usually present the ...
Abstract Studies have been done to determine the levels of human urinary granulocyte colony-stimulating factor in Egyptian patients with active bilharziasis. Colony-stimulating factor levels were measured by a semi-solid tissue culture colony assay with murine bone marrow as the target cell source. The levels in urine from patients with bilharziasis (mean 118) were found to be significantly elevated above control values found in normal human urine (mean 72) derived from the same population. This is the first demonstration of an effect of parasitic infection in man on the granulocyte regulatory system, and opens the way for future studies in this area.
Schistosomiasis (also known as bilharzia) is one of the most prevalent parasitic diseases. It is a poverty-related disease that leads to chronic illness. The threat posed by schistosomiasis is substantial: the WHO estimates that at least 200 million people worldwide required treatment in 2016, of which more than 90% live in Africa.1 Schistosomiasis affects a large proportion of children under 14 years of age, including at least 25 million preschool-age children. In these very young children, prevalence of infection may exceed 60%.2. Schistosomiasis is acquired when people come into contact with fresh water infested with the larval forms (cercariae) of parasitic blood flukes, known as schistosomes. The microscopic adult worms live in the veins draining the urinary tract and intestines. Most of the eggs they lay are trapped in the tissues and the bodys reaction to them can cause massive damage. Left untreated, schistosomiasis can lead to anemia, stunted growth, reduced learning ability and ...
Schistosomiasis (also known as bilharzia) is one of the most prevalent parasitic diseases. It is a poverty-related disease that leads to chronic illness. The threat posed by schistosomiasis is substantial: the WHO estimates that at least 200 million people worldwide required treatment in 2016, of which more than 90% live in Africa.1 Schistosomiasis affects a large proportion of children under 14 years of age, including at least 25 million preschool-age children. In these very young children, prevalence of infection may exceed 60%.2.

Schistosomiasis is caused by infection with trematodes S. mansoni, S. mekongi, S.japonicum and S. intercalatum. Urinary Schistosomiasis is caused by infection with S.haematobium.. Schistosomiasis is known to be highly endemic across Tanzania with published data suggesting that all regions have some level of infection. This can range from 12.7% to 87.6% for schistosomiasis. Urine questionnaire mapping for S. haematobium has been conducted in every school for the entire country in addition to limited mapping by stool examination for S. mansoni prevalence around the Lake Victoria regions.. The major contributory factors to such high levels of infection are limited access to safe water and lack of or poor environmental sanitation. Individuals are therefore continually exposed to the parasites and re-infection levels are high.. The consequences of these diseases globally are well documented, but particularly within Tanzania which has been a major focus for research into the transmission dynamics and ...
In this work the authors develop a mathematical model for the dynamics of a major helminth parasite of man, schistosomiasis. The model is a system of coupled non-linear equations. Numerical experimentations with the model reveal the remarkable stability of the dynamics of schistosomiasis. The steady state is invariably reached within 10-15 years of the start of the infection. A numerical solution of the model supports the often-stated and often-debated observation that the usual shape of the curve of the intensity of infection by age is produced through variability of water-contact behaviour among age groups and a slowly-acquired immunity to re-infection. It also indicates that convexity of the age-intensity profile can be due to variability of water-contact activities among age groups alone. The model can be used to answer questions of the what if variety about the dynamics of schistosomiasis especially as they relate ...

Antibody detection can be useful to indicate schistosome infection in people who have traveled to areas where schistosomiasis is common and in whom eggs cannot be demonstrated in fecal or urine specimens. Test sensitivity and specificity vary widely among the many tests reported for the serologic diagnosis of schistosomiasis and are dependent on both the type of antigen preparations used (crude, purified, adult worm, egg, cercarial) and the test procedure.[32] At the U.S. Centers for Disease Control and Prevention, a combination of tests with purified adult worm antigens is used for antibody detection. All serum specimens are tested by FAST-ELISA using S. mansoni adult microsomal antigen. A positive reaction (greater than 9 units/µl serum) indicates infection with Schistosoma species. Sensitivity for S. mansoni infection is 99%, 95% for S. haematobium infection, and less than 50% for S. japonicum infection. Specificity of this assay for detecting schistosome infection is 99%. Because test ...
Schistosomiasis (bilharziasis), an ancient disease, is a major world public health problem, second only to malaria and tuberculosis. In 1950, an estimated 115 million individuals were affected by this parasitic disease (1); in some endemic areas more than half of the people are infected. The extent to which schistosomiasis contributes to the morbidity and mortality of populations in endemic areas awaits more exact methods of diagnosis and more accurate reporting.. Three species of blood fluke (trematode) produce the disease in man: Schistosoma mansoni, found in the West Indies, northeastern and eastern South America, the Arabian peninsula, and Africa; S. haematobium, ...
The development of an efficient vaccine against human schistosomiasis represents a major challenge for the improvement of health in many developing countries.. Schistosomiasis affects millions people in numerous countries and hampers economical development of tropical areas.. Although progress has been made for the limitation of the disease severity by chemotherapy, continuous re-infection and risks of drug resistance point to the necessary development of alternative strategies.. It is widely agreed that immunological prevention of chronic parasitic infections will be extremely difficult to achieve. Conversely in some major helminth infections like schistosomiasis, where parasite eggs laying in the tissues is the exclusive cause of pathology and the elimination of eggs in nature is the source of transmission, inhibition of parasite fecundity might represent for the future a novel way to prevent the deleterious effects of these chronic infections in man..

GENEVA, December 13, 2011 /PRNewswire/ --. - Number of donated tablets doubled to around 50 million per year Merck Serono, a division of Merck KGaA, Darmstadt, Germany, today announced its intention to further boost its efforts in the fight against the tropical disease schistosomiasis and to continue until the disease has been officially eliminated in Africa. The company plans to double its annual donation of tablets containing the active ingredient praziquantel from 25 million to 50 million in the medium term. The company committed itself to doing so at a meeting with the World Health Organization (WHO) in Geneva. Having originally planned to end the project in 2017, Merck Serono now intends to continue its efforts to fight schistosomiasis indefinitely. Complementary to this donation, Merck Serono will financially support a WHO-led school-awareness program in Africa. The objective is to educate children about the consequences of schistosomiasis and ways to prevent the disease. In addition, ...
Background: Despite major redevelopments and changes to existing health care delivery infrastructure a range of pathologies and associated health problems prevail that impact on society as a whole. Many of these diseases and health problems are directly attributable to lifestyle choices and environmental factors. One of these diseases is Schistosomiasis (also known as bilharzias), a condition still prevalent in countries such as Nigeria, with school age children most commonly affected. This study analysed the specific age distribution of Schistosomiasis and other gastrointestinal (GI) related parasitic infections among children (0-15 years) in Holy Ghost Hospital, Imo State Nigeria from 2012 - 2015. Methodology: Using a retrospective survey design, to provide a quantitatively measurable and statistical description of the subject under study the demographic profiles of 323 children with a clinical diagnosis of Schistosomiasis were collected. Details collated included year of clinical diagnosis, ...
Schistosomiasis is a parasitic disease that blights the lives of millions. It starves sufferers of nutrients - leaving children too weak to learn, parents too exhausted to work and whole families trapped in poverty. For just 50p per child, per year, we can provide life-changing medical treatment. Please give now to support our work. Schistosomiasis is one of several parasitic diseases born of poverty. It is commonplace in countries where there is no proper sanitation and little access to clean water. The parasites - a kind of flatworm - enter the body through contaminated water. Once inside, they feed on the nutrients in their hosts blood, slowly starving them of energy and good health.. ...
Over the past three years, The Carter Center, in partnership with the Nigeria Ministry of Health, has introduced an innovative way of simultaneously treating several parasitic diseases in Nigeria. In this approach - known as triple-drug treatment - a health worker gives a community member three different medicines at one time that in combination treat river blindness, lymphatic filariasis, schistosomiasis, and several kinds of intestinal worms. In the interview that follows, Frank Richards Jr., M.D., who directs the Centers programs for fighting these diseases, discusses the benefits of the triple-drug approach. Learn More ...

Schistosomiasis is an acute and chronic disease, also known as Bilharzia or snail fever. It is caused by different species of blood flukes of the genus Schistosoma, with an estimated 700 million people at risk of infection. The disease burden is difficult to estimate because of hidden pathologies such as bladder and kidney failure or bladder cancer. Estimates therefore vary widely, between 20,000 and 200,000 deaths per year,1 with up to 70 million disability-adjusted life years2 (DALY3: an estimate of the number of healthy life years lost). The disease is transmitted by freshwater snails that release larval forms of the parasite. As a consequence, schistosomiasis is most prevalent in poor communities in tropical and sub-tropical areas, where access to safe drinking water and adequate sanitation are scarce. As children tend to spend time swimming or bathing in water, the worms infect a large proportion of children under the age of 14 in many areas.. The presence of the intermediate host (the ...
Schistosomiasis, also known as Bilharziasis, is caused by a blood fluke whose larvae contaminate fresh water where humans contract the disease by wading, swimming, or bathing.
Schistosomiasis is an important parasitic disease affecting |207 million people in 76 countries around the world and causing approximately 250,000 deaths per year. At present, the main strategy adopted for the control of schistosomiasis is the use of safe chemotherapy, such as praziquantel. Howev …
This is the first study comparing the clinical and hemodynamic characteristics of patients with different forms of PAH in an area endemic for schistosomiasis. Overall, the characteristics of patients with PAH-Sch were similar to those of patients with PAH resulting from other etiologies. Among the 98 included patients with PAH, the prevalence of PAH-Sch was 57.1%, unlike other studies developed in a non-endemic region1414. Lapa MS, Ferreira MV, Jardim C, Martins BC, Arakaki JS, Rogerio S, et al. Características clínicas dos pacientes com hipertensão pulmonar em dois centros de referência. Rer Assoc Med Bras. 2006;52(3):139-43. that showed a prevalence of 30%. This difference can be attributed to the fact that the referral center in the current study is located in a region where disease control remains unsatisfactory, with high morbidity/mortality rates, increasing social and economic costs to the region, and worsening patient quality of life1515.

Schistosomiasis is a waterborne parasitic disease in sub-Saharan Africa, particularly common in rural populations living in impoverished conditions. With the scale-up of preventive chemotherapy, national campaigns will transition from morbidity- to transmission-focused interventions thus formal investigation of actual or expected declines in environmental transmission is needed as end game scenarios arise. Surprisingly, there are no international or national guidelines to do so in sub-Saharan Africa. The article therefore provides an introduction to key practicalities and pitfalls in the development of an appropriate environmental surveillance framework.. ...
Using a mathematical model of schistosomiasis transmission for a distributed set of heterogeneous villages, we showed that the transport of parasites via social and environmental pathways has consequences for parasite control, spread and persistence. First, we found that the condition for sustainable transmission for a connected set of villages was given by the largest eigenvalue of the BRM (λ1(R),1). Using a simple 2-village example, we showed that disease transmission could be sustained regionally even when individual villages did not locally support transmission. By exploring the interplay between different levels of hydrologic and social transport, we found that optimum transmission did not necessarily coincide with the most diffusive transports. Finally, we showed a rather counterintuitive finding related to disease control: in some cases, targeting of villages with high infection, without regard to village interconnections, may not lead to effective control. Sometimes even a simple ...
Human resistance to re-infection with S. mansoni is correlated with high levels of anti-soluble adult worm antigens (SWAP) IgE. Although it has been shown that IL-4 and IL-5 are crucial in establishing IgE responses in vitro, the active in vivo production of these cytokines by T cells, and the degree of polarization of Th2 vs. Th0 in human schistosomiasis is not known. To address this question, we determined the frequency of IL-4 and IFN-γ or IL-5 and IL-2 producing lymphocytes from schistosomiasis patients with high or low levels of IgE anti-SWAP. Our analysis showed that high and low IgE-producers responded equally to schistosomiasis antigens as determined by proliferation. Moreover, patients from both groups displayed similar percentages of circulating lymphocytes. However, high IgE-producers had an increased percentage of activated CD4+ T cells as compared to the low IgE-producers. Moreover, intracellular cytokine analysis, after short-term stimulation with anti-CD3/CD28 mAbs, showed that IgE high

UMN Morris alumna, Dr. Andrea Lund, will present a lecture entitled, "From UMN Morris to Africa: Human-environment dynamics in the eco-epidemiology of schistosomiasis." Human schistosomiasis is parasitic disease that affects 200 million people worldwide and is second only to malaria in the global burden of parasitic disease. The transmission of human schistosomes occurs between freshwater snails and people when free-swimming parasite larvae penetrate the skin of someone who is wading, bathing or otherwise in contact with the water. The occurrence of schistosomiasis is often elevated in settings where water is actively managed for food or energy production. Andrea will discuss how social and environmental factors interact to perpetuate schistosome transmission, highlighting the need for environmental interventions to complement existing pharmaceutical-based controls. Dr. Andrea Lund holds a Ph.D. in Environment and Resources from Stanford University, a Masters of Public Health in Global

Schistosomiasis is caused by trematode worms Schistosoma spp., whose life cycle requires a definitive vertebrate host and an intermediate freshwater snail host. Transmission to humans occurs through exposure to fresh water containing infectious larvae, which can penetrate intact skin before developing into blood-dwelling adult worms. The disease is patchily distributed in parts of South America, Africa, the Middle East, China, and South East Asia, with about 200 million people infected and 20 million suffering severe consequences of infection....
praziquantel (biltricide) is the treatment. 1200 mg, 3x/day, with food, for two days. in case you are incorrect about the parasite ID, you can take a rotation of anti-parasite medication. You can find some protocols in facebook groups. Its very difficult to find accurate diagnosis in the US if you are unlucky enough to have a parasitic infection. But, you can still treat it. If pyrantel was like a miracle, it may be a different parasite than schistosomiasis, like enterobus vermicularis or maybe strongyloides. You may want to do a rotation of different anti-parasite medicines. Good luck and try not to worry, you can get better.. ...
Researchers at the Sackler School of Graduate Biomedical Sciences at Tufts and Tufts University School of Medicine (TUSM) have uncovered a mechanism that may help explain the severe forms of schistosomiasis, or snail fever, which is caused by schistosome worms and is one of the most prevalent parasitic diseases in the world. The study in mice, published online in The Journal of Immunology, may also offer targets for intervention and amelioration of the disease.. ...

During acute schistosomiasis worm ova released from adult S. japonicum elicit potent pro-inflammatory responses along with characteristic granuloma formation, which then causes substantial injuries to organs such as the liver and intestine where the eggs are trapped (Hirata et al., 2001). As a result, anti-inflammatory responses to limit excessive liver injury or intestinal hemorrhage are necessary to prevent host lethality (Herbert et al., 2008). In general, acute schistosomiasis is considered a Th1 disease (de Jesus et al., 2002), and a defect in developing a Th2 response during acute schistosomiasis is associated with high lethality in mice (Rani et al., 2012). Given that alternatively activated M2 macrophages possess a high capacity for secretion of Th2 cytokines, their role in limiting pro-inflammatory responses and granuloma formation during acute schistosomiasis has been highly appreciated.. Previous studies have suggested that the trafficking of monocytes and macrophages from peripheral ...
Female genital schistosomiasis is a neglected manifestation of schistosomiasis and its public health importance is yet to be determined. Symptoms and signs induced by genital schistosomiasis are unspecific and depending on the localisation of the infection the clinical picture is heterogenous. Pathological consequences of female genital schistosomiasis such as infertility may have a considerable impact on the social life of the diseased woman resulting in divorce or reduced chances to marry. In this paper the results of epidemiological, parasitological and clinical investigations of female genital schistosomiasis, which have been carried out in two study villages in Northern Tanzania, are described. The frequency of schistosomiasis of the cervix in women aged 15 to 45 years (38%) was similar to the frequency of urinary schistosomiasis (42%). The main pathological lesions seen were sandy patches, which seem to be pathognomic, leucoplakia and epithelial lesions. In cervical biopsies of women with ...
Brazil is an endemic country for schistosomiasis in the Latin American and Caribbean countries. Pernambuco is a higher-endemic Brazilian state among the 19 states reporting the disease in the country; schistosomiasis affects 102 (55%) of its 185 municipalities. Our objective was to evaluate the effectiveness of the treatment cycles of the SANAR Program (Plan to Reduce and Eliminate Neglected Diseases) in Pernambuco State in Northeast Brazil. A cross-sectional population-based study was conducted in 2014 via a household survey in 117 hyperendemic locations in the state of Pernambuco. We compared the schistosomiasis prevalence rates in hyperendemic locations, aggregated by geographical region, before and after the intervention. The dependent variable was a positive stool test result by the Kato-Katz method, and the main exposure variable was the number of treatment cycles (one/two). The covariables were the regions of the state and socioenvironmental, socioeconomic, demographic and behavioral

Schistosomiasis, a trematode parasite, is an agent of significant human and veterinary disease. It infects over 207 million people globally, with 700 million at risk of infection, mostly in Sub-Saharan Africa and is endemic in 74 countries. Classified as a Neglected Tropical Disease (NTD), it results in chronic health problems, and causes 200,000 deaths a year. NTDs are usually found in developing countries and are most prevalent in the poorest communities; in wealthier regions they have been contained so are less visible than other diseases such as HIV AIDS, tuberculosis and malaria (the big three). Schistosomiasis requires water contact for transmission and therefore thrives in areas where there is poor sanitation and unsafe (or contaminated) water. While schistosomiasis has lower mortality rates than the big three it causes high levels of morbidity, pain and disability.. ...
Schistosomamansoni is responsible for causing schistosomiasis in humans; a major public health problem worldwide. It is estimated that 200 million people, mostly children are infected with schistosomes. Schistosomiasis occurs in 76 tropical countries, 85% of the infections in Africa. InKenya, it is estimated that 3 million people are infected. Schistosome eggs are responsible for most pathology. Even though conventional drugs are effective in the treatment of the disease, very little progress has been achieved on treatment of schistosomiasis in Kenya. Praziquantel (PZQ) is the most effective drug against all adult stages of human schistosomiasis. Being the only drug used for treatment, other drugs should be sought to avoid development of drug resistance. The use of plant extracts in treatment of diseases is universal. Many plants have been used locally for treatment of bilharziasis in Kenya. The aim of this study was to determine Phytochemistry and antischistosomal activity of five plant ...
Chronic intestinal schistosomiasis has been reported to be associated with colonic polyps, colorectal cancer and ulcerative colitis. We aim to investigate the clinical characteristics of intestinal-related lesions caused by chronic intestinal schistosomiasis japonicum. Patients with and without chronic intestinal schistosomiasis were retrospectively enrolled from the endoscopy center of Wuhan Union Hospital from September 1, 2014, to June 30, 2019 with a ratio of 4:1. The characteristics of infected intestinal segments were analyzed in patients with chronic intestinal schistosomiasis. We also compared the characteristics of intestinal-related lesions, including colorectal polyps, colorectal cancer (CRC), ulceration or erosion of the intestinal mucosa and hemorrhoids, between the two groups. A total of 248 patients with chronic intestinal schistosomiasis and 992 patients without chronic intestinal schistosomiasis were analyzed. The most common sites of chronic intestinal schistosomiasis were the sigmoid

The most severe clinical manifestation of bilharziasis occurs when prolonged and extensive obstruction of the pulmonary arterioles by ova leads to pulmonary hypertension and cor pulmonale.. An analysis of 1,100 consecutive autopsies performed in four and one-half years disclosed 54 patients with Schistosomiasis mansoni of the liver and portal hypertension. Of these, 18 (33%) had pulmonary vascular obstruction of such degree as to produce bilharzial cor pulmonale. The clinical characteristics and results of radiographic and cardiac catheterization studies of these 18 subjects, as well as of seven additional living patients, will be discussed. The differentiating features from other conditions leading ...
Ninety-eight Zimbabweans presenting with the nephrotic syndrome (NS) were Investigated In an attempt to determine the role, if any, of schistosomiasis in the pathogenesis of their glomerulopathy. Whilst concomitant bilharzia was proved m 55% of patients, the overall incidence amongst nephrotics was not significantly higher (p>0.05) than in healthy controls. Furthermore, imunofluorescence microscopy employing schistosomal antisera failed to reveal the presence of schistosomal antigen in renal biopsy specimens. Circulating schistosomal antigen was however, demonstrated in the serum of approximately one third of cases overall and in approximately half the patients With proliferative glomerulonephiritis (GN). It is concluded that schistosomiasIs plays no primary role in the genesis of glomerulopathy in Zimbabweans, although it remains possible that the presence of circulating parasitic antigens may exacerbate glomerular injury in the course of glomerulonephritogenic infections

Background: Access to safe water and adequate sanitation are emphasized as important measures for schistosomiasis control. Indeed, the schistosomes lifecycles suggest that their transmission may be reduced through safe water and adequate sanitation. However, the evidence has not previously been compiled in a systematic review. Methodology: We carried out a systematic review and meta-analysis of studies reporting schistosome infection rates in people who do or do not have access to safe water and adequate sanitation. PubMed, Web of Science, Embase, and the Cochrane Library were searched from inception to 31 December 2013, without restrictions on year of publication or language. Studies titles and abstracts were screened by two independent assessors. Papers deemed of interest were read in full and appropriate studies included in the meta-analysis. Publication bias was assessed through the visual inspection of funnel plots and through Eggers test. Heterogeneity of datasets within the ...

At the Global Health Council Conference, I attended an interesting event, Impact of Schistosomiasis and Polyparasitic Infections on Anemia, Growth and Physical Fitness in Children in Coastal Kenya presented by Dr. Amaya Bustinduy of Case Western Reserve University which focused on neglected tropical diseases (NTD).. Schistosomiasis remains one of the most serious and prevalent neglected tropical diseases worldwide. According to Bustinduy, the WHO estimated that there are 235 million cases of schistosomiasis with 732 million to be at risk for contraction. 89% of all cases live in the less-developed areas of rural sub-Saharan Africa and South America.. Schistosomiasis is associated with diseases such as anemia, growth impairment in children, and mental retardation. The focus of Dr. Bustinduys ongoing study in Kenya is to address those morbidities as part of a larger study examining the ecology of transmission of Schistosomiasis. ...
In the province of Kracheh, in Northern Cambodia, a baseline epidemiological survey on Schistosoma mekongi was conducted along the Mekong River between December 1994 and April 1995. The results of household surveys of highly affected villages of the East and the West bank of the river and of school surveys in 20 primary schools are presented. In household surveys 1396 people were examined. An overall prevalence of infection of 49.3% was detected by a single stool examination with the Kato-Katz technique. The overall intensity of infection was 118.2 eggs per gram of stool (epg). There was no difference between the population of the east and west shore of the Mekong for prevalence (P = 0.3) or intensity (P = 0.9) of infection. Severe morbidity was very frequent. Hepatomegaly of the left lobe was detected in 48.7% of the population. Splenomegaly was seen in 26.8% of the study participants.

Looking for snail fever? Find out information about snail fever. see schistosomiasis schistosomiasis , bilharziasis , or snail fever, parasitic disease caused by blood flukes, trematode worms of the genus Schistosoma.... Explanation of snail fever
Where and how snails move is of concern in many developing countries because freshwater snails transmit schistosomiasis, a parasitic disease that affects more than 240 million people worldwide. Each snail can contaminate the water that people work, swim or wash in with many parasites, so movement of just one snail to a new area could introduce the disease in a previously healthy population. The study found that the way humans manage the land and waterways that snails traverse could be enabling their spread.. We dont think of snails as particularly mobile, but the genetic evidence we found - that snails can traverse substantial distances - is a reminder of just how difficult it is to contain and control infectious diseases carried by animals and insects, said Justin Remais, an associate professor of environmental health sciences at UC Berkeley, who led the study.. The study was published Dec. 15 in the journal PLoS Neglected Tropical Diseases.. Read more at UC Berkeley. Related: ...
Despite effective chemotherapy, schistosomiasis remains the second largest public health problem in the developing world. Currently, vaccination is the new strategy for schistosomiasis control. The presence of common antigenic fractions between Schistosoma mansoni and its intermediate host provides a source for the preparation of a proper vaccine. The objective of this paper is to evaluate the nucleoprotein extracted from either susceptible or resistant snails to protect against schistosomiasis. The vaccination schedule consisted of a subcutaneous injection of 50 µg protein of each antigen followed by another inoculation 15 days later. Analyses of marker enzymes for different cell organelles [succinate dehydrogenase, lactate dehydrogenase (LDH), glucose-6-phosphatase, acid phosphatase and 5-nucleotidase] were carried out. Energetic parameters (ATP, ADP, AMP, phosphate potentials, inorganic phosphate, amino acids and LDH isoenzymes) were also investigated. The work was extended to record worm ...

Initially, skin may be itchy and a rash may appear where the Schistosoma burrow into the skin. As the worms develop in the liver, fever, chills, cough, and muscle aches may develop. There may be liver enlargement or malfunction, diarrhea, abdominal pain, and vomiting. The kidneys may be also affected. In rare cases, eggs can reach the brain or spinal cord and cause seizures. Even without treatment, most cases do not result in permanent damage to organs, though there may be significant long-term health effects. Sometimes, however, the infection scars the liver so much that blood flow through the liver is partially blocked. This causes a condition called portal hypertension (POR-tal HY-per-ten-shun), which may cause sometimes fatal bleeding from swollen veins in the stomach and esophagus * . ...

At the end of the assessment, a short report summarizing the fact-finding is produced and discussed with representatives of the organizations that will likely be involved in the project. The most time-consuming and painstaking part is undoubtedly the assessment among the communities. Although transportation and living conditions among the most needy groups are often poorly developed, this important part of the assessment must not be neglected due to time constraints. In order to record the broadest possible diversity of situations, four or five communities with the greatest possibility of heterogeneity (ethnic, socio-economic, infrastructure situation, etc.) should be sought out to assess the variability of the living conditions in the proposed project area.. The following chronological diagrams present two examples for scheduling the activities in rural (Fig. 2) and urban areas (Fig. 3). If communities in urban areas are to be identified and investigated, the time required is shorter because ...
