[Intestinal helminthiasis. III. A program of education and health in helminthiasis].

From August 1985 to June 1986 an Education Program for school-children and their parents or guardians was undertaken in Santa Eudóxia (S. Paulo, Brazil) with a view to the practice of knowledge concerning intervention with regard to parasitic helminths, with the aim of stimulating collective action. A manual of technical orientation for the coordinators had had been prepared. Three groups composed of school-children's parents or guardians was formed and these discussed four basic themes during the Course of Education and Health in Helminthiasis: 1. What the disease is like; 2. The worms which occur in man; 3. The significance of the disease; 4. Prophylactic measures. Each group prepared a manual about the content of the course. The results of the children's work were presented at the Health Education Fair, an event open to the whole community. The way this Program developed made it clear that the population had become aware of the magnitude of the problem. Furthermore, they feel the need of effective measures regarding the control of helminth infestation.

Comparative studies on the evaluation of the effect of new anthelminthics on various intestinal helminthiasis in Iran. Effects of anthelminthics on intestinal helminthiasis.

The effect of pyrantel pamoate, levamisole, mebendazole, thiabendazole and bephenium hydroxynaphthoate on various intestinal helminths were evaluated among the inhabitants of four villages in the Dezful area southwest of Iran. A total number of 328 persons, all infected simultaneously with Ascaris and hookworm (Ancylostoma duodenale) and 49.2% with Trichostrongylus spp., were randomly divided into six groups. One group was kept as the control and the other five were each treated with one compound. Follow-up examinations showed that all of the drugs used were highly effective on Ascaris, and the differences in the cure rate were not statistically significant except for bephenium hydroxynaphthoate which showed a lower cure rate. For hookworm, cure rates of 100, 90, and 85% were observed with levamisole, pyrantel pamoate and bephenium hydroxynaphthoate, respectively. Cure rates observed with mebendazole and thiabendazole were 35 and 51%, respectively. For Trichostrongylus, the highest cure rate was achieved with levamisole, followed by thiabendazole and mebendazole. While the percentage of people showing side-effects was rather low for all drugs, thiabendazole and bephenium hydroxynaphthoate produced a higher, and levamisole a lower, percentage of side effects.

[An assessment of the helminthiasis situation in Belorussia by the dynamics of the mean multiyear indices of population morbidity].

The study of population morbidity with helminthiasis prevalence in Byelorussia has revealed 11 nosological entities and has established that in 99.9% these were cases of ascariasis, trichocephaliasis and enterobiasis. In 1981-1989 dynamics of ascariasis and trichocephaliasis morbidity was characterized by a marked tendency towards its decrease, while there was a tendency towards moderate growth in enterobiasis morbidity. The values of the (intensive) rates of helminthiasis morbidity during the examination of hundreds of thousands people does not considerably depend on the fluctuations of the number of persons examined on the presence of helminths. To elaborate systems for epidemiologic surveys of helminthiasis it is necessary to increase the volume and improve the quality of information on the morbidity rates.

Helminthiasis

Canine and human gastrointestinal helminthiasis of the Kainji Lake area, Nigeria.

An investigation into gastrointestinal helminthiasis in human and dog population of the Kainji Lake area revealed a high prevalence of helminthiasis which may be due to lack of adequate health and veterinary facilities; crowdiness and squalid environment. The prevalent parasites in humans were Ancylostoma sp, 40.33%; Ascaris lumbricoides, 44.07% and Strongyloides stercoralis 4.05%, while in dogs Ancylostoma sp, 36.95%, Dipylidium caninum, 28.26%, Echinococcus granulosus, 8.69% and S. stercoralis 5.43%. The risk of incidental occurrence of helminths of dog, D. caninum, Toxocara canis, E. granulosus are highlighted and the need to educate the community on hygiene matters in the absence of adequate health facilities are recommended.

Helminthiasis, mite-allergy and IgE in a homogenous tropical population.

Of 77 eosinophilic male adolescents studied, 12% were found to have helminthiasis and high circulating serum levels of IgE to Dermatophagoides pteronyssinus. This shows that worm-infested individuals can still mount high IgE responses to atopic non-helminthic allergens. The total serum IgE levels of these individuals were not significantly different from those with helminthiasis only, suggesting that there may be some form of repression of helminth-induced non-specific IgE in the presence of atopy; alternatively, allergen-related IgE may be repressed when an individual is worm-infested.

The prophylactic effect of ivermectin treatments on gastrointestinal helminthiasis of calves turned out early on pasture or late on mown pasture.

A study was undertaken to ascertain the prophylactic effect on gastrointestinal helminthiasis of (1) a single ivermectin treatment of calves 3 weeks after a late turnout on mown pasture and (2) two ivermectin treatments of calves 3 and 8 weeks after an early turnout. The single ivermectin treatment after a late turnout on mown pasture appeared to be an effective control measure for infections of Cooperia and, in particular, Ostertagia. The two treatments after an early turnout were also effective, although less so than the single treatment combined with the late turnout on mown pasture. Ivermectin treatment had no effect on the faecal egg output or the pasture larval counts of Nematodirus helvetianus. The proportion of inhibited early fourth stage larvae of Ostertagia was much higher in the control group than in either of the experimental groups.

Ivermectin in the control of helminthiasis in guinea fowl Numida meleagris galeata Pallas.

Guinea fowls (Numida meleagris galeata Pallas) were treated with subcutaneous injection of Ivomec at dose rate of 0.14 mg/kg to control and reduce mortalities due to helminthiasis. Ten hours after treatment faecal droppings contained both adult and larval stages of Ascaridia galli, Heterakis gallinarum, Subulura suctoria and fragments of Raillietina spp. Recovery was found 48 hours later. Drug efficacy was 100%.

An economic analysis of two schemes for the anthelmintic control of helminthiasis in weaned lambs.

The economic benefit obtained from 2 schemes for the strategic control of helminthiasis in weaned lambs has been assessed in the Western District of Victoria. The results were compared with those from sheep in control groups which were given a single anthelmintic treatment during an outbreak of helminthosis. Mortality in sheep receiving the critical treatment scheme of 2 appropriately timed anthelmintic treatments was 12%, compared with 22% in the group receiving the traditional series of summer and autumn treatments, and 26% in the control group. As a result of this difference in mortality rate, the critical treatment scheme was the most profitable control strategy at 1970-71 prices, yielding a net benefit of $70 per 100 sheep in comparison with the control group which received no strategic treatment. This is 538% return on funds invested in anthelmintic treatment. The benefit from this scheme was not unduly affected by variation in wool or sheep prices, nor to possible differences in mortality rate within the expected range. The traditional treatment scheme also yielded positive net returns, but the results were adversely affected by a small change in mortality rate and therefore could not be recommended for routine use on commerical farms.

Ivermectin in the treatment of helminthiasis in caged raised adult guinea-fowl (Numida meleagris galeata Pallas).

The treatment of natural infections of helminthiasis in caged raised guinea-fowls indicates a high efficacy of ivermectin in the elimination of infection due to both juvenile and adult stages of Heterakis gallinarum, Ascaridia galli, Subulura suctoria, Raillietina spp. and Capillaria caudinflata at dose levels of 0.07 mg/kg and 0.14 mg/kg per adult bird, subcutaneously administered. Guinea-fowls treated responded with no observable side effect and remained clean of any helminth infection for over 6 weeks. Discussion on the broad-spectrum and cost-effectiveness of the drug are briefly mentioned.

Changes in blood values of sheep suffering from acute and chronic helminthiasis.

Systematic blood changes in two groups of sheep, one suffering from acute and the other from chronic helminthiasis were studied. In the group with acute infection, there was a rapid increase in helminth egg output coupled with rapid decline in the values of packed cell volume (PCV), haemoglobin (Hb) and red blood cells (RBC). Fluctuations were observed in the value of white blood cells (WBC). In the group with chronic infection, a slow and unsteady increase in helminth egg output was accompanied by a slow and steady fall in the values of PCV, Hb and RBC. As with acute infection, the value of WBC was unsteady.

Eosinophilia, elevated immunoglobulin E level and chronic enteritis due to intestinal helminthiasis.

Recurrent urticaria, abdominal pain, peripheral eosinophilia, hyperimmunoglobulin E and small bowel abnormalities on roentgenograms prompted evaluation of a 36 year old man for intestinal parasitism. Evidence for helminthiasis as the cause of his symptoms included changing antibody titers to helminth antigens and a dramatic response to therapy. Helminth larvae or eggs were not recovered. Diagnosis of strongyloidiasis, the most likely cause of the illness, is discussed.

Treatment of multiple intestinal helminthiasis with oxantel and pyrantel.

32 elementary school children were treated for multiple intestinal helminthiasis (ascariasis, trichuriasis and hookworm infections) with a combination of the pamoate salts of oxantel and pyrantel in a dose of 15 to 20mg/kg body weight of each in 1 daily dose for 3 consecutive days. The cure rate for ascariasis was 96.7%, and 84.4% for both trichuriasis and hookworm infections. 68.7% were completely cured of all 3 helminths. However, among those not completely cured, only 1 species of the previous 3 infecting helminths was present after treatment and then with a very marked reduction in egg count.

[Comparison of several coproparasitological techniques for the diagnosis of soil-transmitted intestinal helminthiasis].

Five hundred and eleven samples of feces were examined by several coproparasitological techniques: Kato-Katz, Willis, Ritchie and direct wet mount. It was found that Kato-Katz was the most reliable technique for the diagnosis of Trichuris trichiura, Necator americanus, and Ascaris lumbricoides, demonstrating the largest number of cases. Willis, Ritchie and direct wet mount were effective in that order. Taking into account that Kato-Katz is a quantitative method, it should be recommended in the diagnosis of soil-transmitted helminthiasis.

Intestinal helminthiasis and abdominal symptoms in adults.

In a study to test the association between soil transmitted intestinal helminthiasis and abdominal symptoms in a non-paediatric age group, 242 randomly selected patients (137 males, 105 females, median age 45 years) were asked specific questions pertaining to abdominal symptoms at the time of admission to the adult medical wards. Stool examination on all patients revealed a round worm prevalence rate of 21%. A larger proportion of stool positive female patients were symptomatic than stool negative females (68% vs 30%, p = 0.04). There was no significant difference in symptoms between stool positive and stool negative male patients (34.6% vs 31%, p = 0.91). The results suggested an association between intestinal nematode infection and abdominal symptoms in females but not in males.

Abdominal Pain

Intestinal helminthiasis in ex-patriates returning to Britain from the tropics. A controlled study.

A retrospective study was performed of clinical features in expatriates attending the Hospital for Tropical Diseases, London, with a sole diagnosis of ascariasis (100), trichuriasis (100), hookworm (75), and strongyloidiasis (36). Results were compared with a control group of 100 ex-patriates attending the same hospital in whom no diagnosis was made and in whom stool microscopy and peripheral blood eosinophil counts were normal. Almost one half of all patients with intestinal helminthiasis were asymptomatic. Of those with symptoms specific clinical features were no different from controls with the exception of a transient itch or rash in patients with strongyloidiasis. The presence of eosinophilia was not a reliable indicator of infection. This study suggests that it may be worth while performing stool microscopy in ex-patriates returning from the tropics even if they are asymptomatic.

[Seroepidemiologic studies in helminthiasis].

Epidemiological parameters subjected to variations corresponding to immunological structure of population are outlined on the basis of brief characteristics of immunity specificity in helminthiasis patients. Main trends in seroepidemiological studies are established. Authors analyzed the feasibility of assessment of some constituents of epidemic processes of various nosoforms by means of serological screening at the population level.

[Intestinal helminthiasis on Ancien-Fresco island (Ivory Coast)].

An epidemiologic survey has been done in November 1987 on 220 children aged from one to four in the Ancien-Fresco island (Côte-d'Ivoire). The results show that 84.5% of the children whose excreta have been examined have parasites. The Ascaridiasis is the helminthiasis the most frequent.
