Intestinal parasitic diseases in Riyadh, Saudi Arabia: prevalence, sociodemographic and environmental associates.

Our objectives were to assess the prevalence of intestinal parasitic infections in Riyadh and to determine associated sociodemographic and environmental factors. The study was conducted through a household survey. Three health centres were chosen from each of the five Riyadh urban regions and 15 from rural areas. Based on the average family size, a random sample of households were chosen. All household members were asked to participate in the study. Data were collected using a pre-designed questionnaire eliciting data on sociodemographic and environmental factors. A stool specimen of each individual was examined microscopically for the presence of trophozoites and cysts. Six thousand and twelve participants with a mean age of 23.3 +/- 17.4 (median 19 years, 48.6% males) were studied and 32.2% were infected. The infection rate was high in urban areas (33.3%), among children < 12 years (34.4%), non-Saudis (42.2%), single persons (34.9%), illiterate individuals (33.8%), those who obtained drinking water from tankers (36.1%) and those who disposed of sewage in open channels (47.1%). Stratified analysis showed that for Saudis <12 years parasitic infections were significantly higher among tanker users (39.5%) and septic tank users (36.8%). For Saudis> or =12 years low education, water storage and open sewage disposal were statistically associated with parasitic infections (P < 0.05). Among expatriates, infections were high among males (47.6%), urban residents (48.3%), single persons (46.9%), tanker users (39.5%) and septic tank users (78.6%). Multivariate logistic regression analysis showed that age < 12 years, non-Saudi nationalities, educational level below secondary school, tanker as source of water and open sewage disposal were independently associated with high intestinal parasitic infection.

[Training for diagnosis of intestinal parasitic diseases in the national laboratory system of Cuba].

A national training project in the diagnosis of intestinal parasites was conducted in 1997. An initial national course was followed respectively by courses in the Central, Eastern, and Western Provinces. Our results showed that Cryptosporidium parvum, Cyclospora cayetanensis, and leukocytes showed a significantly lower percentage of errors after the training than before (p < 0.01). The same occurred with Entamoeba histolytica/E. dispar and Chilomastix mesnilii (p < 0.05). Among the helminths, Taenia spp., Fasciola hepatica, and hookworm showed significantly fewer errors after the training (p < 0.01). In the other specimens, few mistakes were found both at the beginning and after the training, and the percentage of errors did not change (p > 0.05). Furthermore, when comparing scores before and after training, a significant increase in median scores appeared in the Central Provinces (p < 0.05), Western Provinces (p < 0.01), and in the entire series (p < 0.01). The results showed the effectiveness of this intervention; these periodic mandatory training courses should be developed together with national programs for quality assessment in Parasitology.

Prevalence of intestinal parasitic disease agents in stools of people in a rural area of Nigeria.

Little is known of the prevalence of intestinal parasites in rural areas of Nigeria because there are few published data and laboratories in these areas are rarely well equipped for parasitological work. During a survey of a Nigerian village, Ascaris and hookworms were found to be the commonest helminths and Entamoeba coli the commonest protozoan. Differences in parasite prevalences between rural and urban areas of Nigeria are related to occupation, cultural patterns, and physical, social and biological environments.

Treatment of intestinal parasitic disease.

Although improved sanitation in the United States has resulted in a general diminution in the prevalence of intestinal parasitic infections, some, such as enterobiasis, are not reduced by improved environmental or water sanitation and others, such as amebiasis and hookworm infection, persist in foci. Other infections, notably giardiasis, have increased due to the travels of American tourists in other countries where environmental sanitation is poor. North American physicians, therefore, may expect at some time to have to treat parasitic infections. Favored chemotherapeutic agents currently are: for amebiasis--metronidazole and diiodohydroxyquin; for giardiasis--metronidazole; for tapeworm infections--niclosamide; for enterobiasis--pyrantel pamoate, piperazine citrate, or pyrvinium pamoate; for ascariasis--piperazine citrate; for stronglyoidiasis--thiabendazole; for trichuriasis--mebendazole; for hookworm infection--pyrantel pamoate; for schistosomiasis japonica--tartar emetic; and for schistosomiasis mansoni--niridazole.

[Dynamics of intestinal parasitic diseases in children admitted to the TB Preventorium in Gorneşti, Mureş county].

This study follows the evolution of the intestinal parasitic infections during a 5 year period between 2000-2004, detected at the inhabitants of the TBC Preventorium Gornesti from Mureş county. The 127 children included in the study are aged between 3 and 16 year, they attend a special kindergarten and a special school. The most important species of parasites found were Giardia lamblia, Ascaris lumbricoides, Hymenolepis nana and Trichuris trichiura. Most of the infected children had mono-parasitosis, only a few showed poly-parasitic infections with 2 parasites. In spite of the adequate treatment, the infections did not disappear, but neither did their number increase.
