Soil-Transmitted Helminthiasis is caused by nematode worm infections, namely Ascaris lumbricoides (round worm), Trichuris trichiura (whipworm) and Necator americanus or Ancylostoma duodenale (hookworm). At present, the prevalence of Soil-Transmitted Helminthiasis in Indonesia is still high. To reduce the prevalence of Soil-Transmitted Helminthiasis in Indonesia, the Ministry of Health of the Republic of Indonesia holds a mass worm treatment program for pre-school age children and school-aged children. The drug given is albendazole 400 mg single dose. This study aimed to determine the effectiveness of a single dose of albendazole 400 mg against infections of Ascaris lumbricoides and Trichuris trichiura. This study used a Pre-Experiment research design (One Group Pretest-Posttest). The research subjects were 66 people. Subjects positive for Ascaris lumbricoides were 37 people (mild infection 67.57%, moderate infection 27.03% and severe infection 5.41%). After giving a single dose of albendazole 400 mg to 37 people who were positive for Ascaris lumbricoides, 37 people had not found eggs of Ascaris lumbricoides on faecal examination after treatment. Positive subjects Trichuris trichiura were 54 people (mild infections 51.85%, moderate infections 44.44% and severe infections 3.73%). After giving a single dose of albendazole 400 mg to 54 positive people Trichuris trichiura, in severe infections, the percentage of eggs dropped was 100%. In moderate infections, the percentage of the number of eggs dropped is 95.83%. In mild infections, the percentage of total recovery was 7.14%, and the percentage of eggs dropped was 39.29%. The results of the Wilcoxon test on Ascaris lumbricoides obtained a significance value of <0.05, which means that there are significant differences in the examination before treatment and after treatment. The results of the Wilcoxon test on Trichuris trichiura obtained a significance value of 0.05, which means there were no significant differences in the results of the examination before treatment and after treatment. Albendazole 400 mg single dose is effective against Ascaris lumbricoides infection and is not effective against Trichuris trichiura infection.

SUMMARYAppetite and growth were studied in primary schoolboys (6–10 years) infected with Ascaris lumbricoides (86%) and Trichuris trichiura (100%) who received a single dose of pyrantel pamoate (which has little or no effect on Trichuris trichiura ) or a placebo. Boys were examined, allocated at random by descending Ascaris egg count to pyrantel (PR, n = 36) or placebo (PL, n = 36) groups, treated, and re-examined 3 and 7 weeks later. The 2 groups did not differ significantly before treatment in helminth infections, appetite, or growth. Three and 7 weeks after treatment, the PR group exhibited significantly greater increases than did the PL group in weight (0·2 kg and 0·4 kg more, respectively) and percentage weight-for-age (0·6% and 1·7% points more, respectively). Appetite increased significantly in the PR group at 3 and 7 weeks (P < 0·0005 and P < 0·01, respectively) but not in the PL group. The prevalence and intensity of A. lumbricoides infection were greatly reduced in the PR group at 3 and 7 weeks (both P < 0·0001) but not in the PL group. We conclude that treatment with pyrantel pamoate may improve appetite and growth in schoolchildren in areas where A. lumbricoides infections and poor growth are highly prevalent.

Prevalence of soil transmitted helminthes infections in apparently healthy school going children and other 528 people of different districts of Koshi regions of North Bihar were evaluated. Over all incidences of STHs infection was 39.39% during study. High incidence of STH was seen in the rainy season i.e., in the month of July and August, September, significantly higher (P<0.05) .The incidence of Ascaris lumbricoides was highest in the month of August (18.64%). The month of September was 15.25% followed by that of July (14.4%) and October with 10.16%. Also the incidence of hookworm registered the highest incidence in the month of June (19.27%) and lowest in the month of December (4.82%) during the study period. However prevalence of Trichuris trichiura was negligible and it was almost nil in the most of the months but was highest in month of September with 28.57% and lowest in October with 14.00% The climatic factors are responsible for soil transmitted helminthes which are temperature, rainfall and relative humidity. Ascariasis, Trichuriasis and Ancyclostomiasis (Hookworm infection) are found to be endemic in this region.

Procurou-se avaliar métodos e soluções tradicionalmente utilizados na evidenciação de ovos de helmintos parásitos, de fezes ou do solo, em amostras de areia de praia experimentalmente contaminadas com ovos de Ascaris lumbricoides, Trichuris trichiura, Toxocara canis e Ancylostoma sp. Das soluções classicamente utilizadas, a de Dicromato de Sódio (d= 1,350) foi a que apresentou melhores resultados (índice de recuperação = 50%) para ovos de Ascaris, em 24 horas de observação. As duas soluções propostas: Carbonato de Sódio (d= 1,040) e Detergente aniônico sintético - Sulfonato de Sódio (d= 1,040), apresentaram índices de recuperação surpreendentes, superiores a 80% para os ovos de Ascaris, em 24 horas de observação. Conclui-se que o detergente de uso doméstico, pelo seu baixo custo e facilidade de aquisição, pode ser usado na avaliação de rotina da contaminação de areias de praias pelos ovos de enteroparasitos, importantes indicadores de contaminação fecal, necessários a um adequado monitoramento sanitário do meio.

1 - Foram examinadas as fezes de 2.666 indivíduos, operários e funcionários de duas Emprésas industriais, situadas, uma na cidade do Rio de Janeiro e outra no Estado do Rio (Brasil); 2 - Dos 2.666 indivíduos, 1941 (72.80%) estavam parasitados por um ou mais helmintos e 725 (27,20%) tinham seus exames de fezes negativos; 3 - De cada um dos 2.666 indivíduos foi feito um hemograma completo, tendo sido aproveitada a taxa de eosinófilos que, em associação com os exames de fezes, constituiu o objeto principal dêste trabalho. 4 - Na Tabela A observa-se o número de vêzes em que cada um dos vermes foi observado e seus respectivos percentuais. Embora não seja um trabalho de epidemiologia, verifica-se que 46,81% são infestados pelo Trichuris trichiura; 23,85% pelo Strongyloides stercoralis; 22,46% pelo Necator americanus e/ou Ancylostoma duodenale; 20,51% pelo Ascaris lumbricóides; 1,65% pelo Schistosoma mansoni; 0.67% pelo Enterobius vermicularis; 0,26% por Taenia solium ou T. saginata e 0,11% por Hymenolepis nana; 5 - Os exames de fezes foram feitos pelos métodos de Faust (ou de Ritchie), de Willis, de Baermann e de sedimentação; 6 - A eosinofilia anotada foi a relativa ou em seu percentual, sendo considerada hipereosinofilia uma taxa de eosinófilos igual ou superior a 5% (Eo > 5%); 7 - Foram abordados de modo conciso os fatores que provocam oscilações na eosinofilia normal tais como a idade, a raça, as horas do nictêmero, os fatores físicos, o sexo, os fatores químicos e outros; 8 - Tratou-se de modo mais extenso das diferenças entre as hipereosinofilias parasitárias e não parasitárias, tendo sido focalizada a dinâmica da eosinofilia traduzida na curva de Lavier. 9 - A distribuição dos 2.666 casos foi feita pelos diferentes graus de eosinofilia, tendo sido levantados gráficos e traçadas curvas sôbre a distribuição de cada helminto e de suas associações. 10 - Por ser necessário à explanação do assunto, foi criado o "índice eosinofilico", o qual corresponde à relação entre o número de casos de um determinado grupo com Eo > 5% e Eo < 5%. Para o total de casos positivos, ao "índice eosinofílico" denominamos "índice eosinofílico médio" em para o total dos negativos "índice eosinofílico residual"; 11 - Estabelecendo-se o "índice eosinofílico", pode-se ajuizar a capacidade eosinofilogênica de cada helminto isoladamente, bem como a de suas associações; 12 - Atenção especial foi dada aos problemas da existência da hipereosinofilia nos casos com exames coprológicos negativos para helmintos, tendo-se passado em revista vários dos aspectos biológicos que o assunto comporta; 13 - Outra questão de grande importância clínica explanada neste trabalho é a do encontro de casos de parasitismo por vermes, sem hipereosinofilia. O autor, baseado em seus dados e em outros colhidos na literatura sôbre o assunto, discute a fisiopatologia da eosinopoiese nas helmintoses e ojerece uma interpretação para êste fato ainda não defintivamente esclarecido.

Background Soil-transmitted helminth (STH) infections remain a public health problem in developing countries. Their prevalence is particularly high in rural areas with people of low socioeconomic level. A single or mixed STH infection rarely causes death, but can affect nutritional status, growth, cognitive development and human health, especially in children.Objective To compare the nutritional status of STH-infected and uninfected children.Methods This cross-sectional study was conducted in June 2010 in children from 3 primary schools in the Simpang Empat and Kabanjahe Subdistricts, Karo District, North Sumatera Province. Fecal examinations were done by the Kato-Katz method to diagnose STH infections. Participants of this study consisted of 140 infected children and 141 uninfected children. Nutritional status classification was based on the 2000 Centers for Disease Control growth charts. All categorical data were analyzed by Chi-square test.Results Of 140 infected children, 8.6% were infected with Ascaris lumbricoides, 17.1% with Trichuris trichiura and 74.3% with mixed infections (Ascaris lumbricoides and Trichuris trichiura). We found significantly more STH infected children with mild to moderate malnutrition than the uninfected group. We also found significantly more mildly to moderately malnourished children with moderate infection intensity than mild infection intensity.Conclusion We find significantly more STH infected children with mild to moderate malnutrition than the uninfected group. We also find significantly more mildly to moderately malnourished children with moderate infection intensity than mild infection intensity. Higher severity of infection is associated with lower nutritional status.

Latar belakang: Infeksi kronis dari soil transmitted helminth (STH) dapat menyebabkan gangguan gizi, pertumbuhan dan kognitif pada anak. Untuk mengurangi dampak infeksi STH, diperlukan identifikasi faktor risiko. Penelitian ini bertujuan untuk mengidentifikasi faktor risiko yang berhubungan dengan infeksi STH pada siswa sekolah dasar di Desa Seraya Timur, Karangasem, Bali. Metode: Penelitian ini menggunakan desain potong lintang dengan mengambil total sampel. Penelitian dilaksanakan pada bulan Januari 2020. Data primer mengenai faktor-faktor risiko infeksi STH dikumpulkan dengan menggunakan kuesioner. Diagnosis infeksi STH dilakukan dengan pemeriksaan tinja dengan metode Kato-Katz. Analisis data menggunakan uji chi-square untuk menentukan faktor risiko yang berhubungan dengan infeksi STH. Hasil: Sebanyak 83 siswa yang berusia 6-12 tahun berpartisipasi dalam penelitian ini. Terdapat 9 siswa (10.84%) yang terinfeksi STH dengan intensitas infeksi ringan. Sebanyak 55.56% terinfeksi Trichuris trichiura, 33.33% terinfeksi Ascaris lumbricoides dan 11.11% terinfeksi cacing tambang. Terdapat beberapa faktor risiko yang memiliki hubungan bermakna dengan infeksi STH diantaranya adalah sering bermain tanah (OR=6.86; 95%CI 1.326-35.494), bermain tanpa alas kaki (OR=10.5; 95%CI 1.249-88.278) tidak mencuci tangan setelah bermain tanah (OR=9.450; 95%CI 1.809-49.358) dan tidak memotong kuku secara rutin (OR=6.462; 95%CI 1.250-33.388).  Pemberian obat cacing setiap enam bulan mampu memberikan efek proteksi terhadap infeksi STH (OR=0.085; 95%CI 0.016-0.449). Kesimpulan: Kebersihan diri menjadi faktor risiko yang berhubungan dengan infeksi STH. Direkomendasikan untuk meningkatkan promosi kesehatan terkait kebersihan diri disamping pemberian obat cacing setiap enam bulan. Kata kunci: Faktor risiko, infeksi STH, anak sekolah dasar   Abstract   Background: Chronic soil transmitted helminth (STH) infection might cause nutritional, growth and cognitive impairment in children. Identifying the risk factors of STH infection is crucially needed to minimize the infection effects. This study aimed to identify risk factors associated with STH infections among primary school students in Seraya Timur Village, Karangasem, Bali. Methods: This study used a cross-sectional design with a total sampling method. The study was conducted in January 2020. Risk factors data were collected using a questionnaire. The diagnosis of STH infection was done by stool examination with the Kato-Katz method. The chi-square test was used to determine the risk factors associated with STH infection. Results: 83 students with ages ranging from 6-12 years participated in this study. There were 9 students (10.84%) whose infected with mild infection of STH. 55.56% of students were infected by Trichuris trichiura, 33.33% were Ascaris lumbricoides infections and 11.11% were hookworm infections. There were several risk factors that significantly associated with STH infection including ground’s playing (OR=6.86; 95%CI 1.326-35.494), barefoot (OR=10.5; 95%CI 1.249-88.278), did not wash hands after playing soil (OR=9.450; 95%CI 1.809-49.358) and did not routinely cut their nails (OR=6.462; 95%CI 1.250-33.388). Deworming every six months could provide a protective effect against STH infection (OR=0.085; 95%CI 0.016-0.449). Conclusion: Personal hygiene is a risk factor associated with STH infection. It is recommended to increase personal hygiene promotion besides dewormed every six months. Keywords: Risk factors, STH infection, primary school students
