          Abstract

          Poor growth and intestinal parasitic infections are widespread in disadvantaged urban children. This cross-sectional study assessed factors influencing poor growth and intestinal parasites in 376 children aged three to six years in daycare centers in Salvador, in the Northeast Region of Brazil. Data was obtained from seven daycare centers on child weight, height, socio-economic status, health and intestinal parasites in stool samples. Prevalence of moderate underweight (< -1SD > -2SD), wasting and stunting was 12%, 16% and 6% respectively. Socioeconomic status, birth order, and maternal weight were predictors of poor anthropometric status. Almost 30% of children were infected with more than one intestinal parasite. Helminths (17.8%), notably Trichuris trichiura (12%) and Ascaris lumbricoides (10.5%), and protozoan Giardia duodenalis (13%) were the most common types of parasites detected. One percent of children had hookworm and Cryptosporidium sp. and 25% had non-pathogenic protozoan cysts. Boys from families with very low socio-economic status had lower linear growth and presented a greater risk of helminth infection. Deworming is considered an alternative for reducing the prevalence of intestinal parasitic infections in this age group.

          Déficit de crescimento e parasitoses são comuns entre crianças residentes em periferias. Em estudo transversal com 376 pré-escolares (3-6 anos) de creches em Salvador, Nordeste do Brasil, avaliamos fatores predisponentes para déficit de crescimento e parasitose. Obtiveram-se dados em sete creches sobre peso da criança, altura, nível socioeconômico, estado de saúde e parasitos em amostras de fezes. Prevalência de baixo peso (-1 < DP > -2), desnutrição e baixa estatura foram 12%, 16%, e 6%, respectivamente; nível socioeconômico, ordem de nascimento e peso materno foram preditores da antropometria. Aproximadamente 30% estavam infectados com ≥ 1 parasita. Helmintos (17.8%), notavelmente Trichuris trichiura (12%) e Ascaris lumbricoides (10.5%) e protozoário Giardia duodenalis (13%) foram os mais comuns; < 1% tinha ancilostomíase e Cryptosporidium sp.; 25% apresentaram protozoários cistos não patogênicos. Meninos de famílias muito pobres tiveram menor crescimento e maior risco de helmintose. A desparasitação pode ser considerada uma alternativa para a redução da prevalência de parasitoses intestinais nesse grupo etário.

              Epidemiology and control of human gastrointestinal parasites in children.

              Parasites found in the human gastrointestinal tract can be largely categorized into two groups, protozoa and helminths. The soil-transmitted helminths (Ascaris lumbricoides, hookworm and Trichuris trichiura) are the most prevalent, infecting an estimated one-sixth of the global population. Infection rates are highest in children living in sub-Saharan Africa, followed by Asia and then Latin America and the Caribbean. The current momentum towards global drug delivery for their control is at a historical high through the efforts of numerous initiatives increasingly acting in coordination with donors, governments and local communities. Together, they have delivered enormous quantities of drugs, especially anthelmintics to children through nationwide annual or biannual mass drug administration largely coordinated through schools. However, a much larger and rapidly growing childhood population in these regions remains untreated and suffering from more than one parasite. Mass drug administration has profound potential for control but is not without considerable challenges and concerns. A principal barrier is funding. Stimulating a research and development pipeline, supporting the necessary clinical trials to refine treatment, in addition to procuring and deploying drugs (and sustaining these supply chains), requires substantial funding and resources that do not presently exist. Limited options for chemotherapy raise concerns about drug resistance developing through overuse, however, satisfactory pharmaco-epidemiology and monitoring for drug resistance requires more developed health infrastructures than are generally available. Further, the limited pharmacopeia does not include any effective second-line options if resistance emerges, and the research and development pipeline is severely depressed. Herein, we discuss the major gastrointestinal protozoa and helminths reviewing their impact on child health, changing epidemiology and how this relates to their control.
