Asociación de fascioliasis con el estado nutricional y coinfección enteroparasitaria en niños / Association of fascioliasis to nutritional status and enteroparasite coinfection in children

Introducción: La fascioliasis es causada por el trematodo Fasciola hepatica que afecta a animales herbívoros, omnívoros y al humano. Los niños de edad escolar son los más afectados y el órgano más dañado es el hígado. Este parásito requiere de reservorio y huésped intermediario para completar su ciclo biológico. Objetivo: Determinar la asociación de la fascioliasis con el estado nutricional y coinfección enteroparasitaria en niños. Métodos: La investigación se realizó entre septiembre de 2016 y abril de 2017 en el distrito de Santa María de Chicmo, región Apurímac. El estudio fue analítico de corte transversal. La población de niños de 6 a 16 años estuvo constituida por 2 172 individuos. El tamaño de muestra fue de 435 niños y se determinó mediante un muestreo simple al azar. Además, para que el muestreo fuera más eficiente se distribuyó el tamaño total de la muestra entre los estratos I.E. Primaria e I.E. Secundaria, para un resultado de 209 y 226 muestras, respectivamente. Sin embargo, se logró tomar 493 muestras coprológicas y serológicas repartidas proporcionalmente entre la totalidad de 23 instituciones educativas. Resultados: La prevalencia de fascioliasis fue de 5,3 por ciento (26/493; IC95 por ciento =3,2-7,4). Las instituciones educativas con mayor prevalencia fueron: Taramba con 17,2 por ciento (5/29; IC95 por ciento = 5,9-35,8), Libertadores de América con 16,1 por ciento (5/31; IC95 por ciento = 5,5-33,7), Mariano Melgar con 15 por ciento (3/20; IC95 por ciento = 3,2-37,9) y Nuestra Señora de Guadalupe con 10,8 por ciento (4/37; IC95 por ciento = 3-25,4). No se encontró asociación de fascioliasis con la valoración nutricional antropométrica ni con la coinfección enteroparasitaria en niños (p˃ 0,05). Conclusiones: La fascioliasis no estaría afectando el estado nutricional de los niños; asimismo, los signos clínicos, atribuidos a fascioliasis, corresponderían también a la alta presentación de parásitos entéricos(AU)

Introduction: Fascioliasis is caused by the trematode Fasciola hepatica and affects herbivorous and omnivorous animals as well as humans. Schoolchildren are the most affected group, and the organ most commonly targeted is the liver. This parasite requires an intermediate reservoir and host to complete its biological cycle. Objective: Determine the association of fascioliasis to nutritional status and enteroparasite coinfection in children. Methods: An analytical cross-sectional study was conducted from September 2016 to April 2017 in the district of Santa María de Chicmo, Apurímac Region. The child population aged 6-16 years was composed of 2 172 individuals. The sample size was 435 children, and it was determined by simple random sampling. Additionally, in order for the sampling to be more efficient, the total sample size was distributed between the strata Primary E.I. and Secondary E.I., for 209 and 226 samples, respectively. However, 493 coprological and serological samples were proportionally taken from the total 23 educational institutions. Results: Prevalence of fascioliasis was 5.3 percent (26/493; CI95 percent=3.2-7.4). The educational institutions with the highest prevalence were Taramba with 17.2 percent (5/29; CI95 percent= 5.9-35.8), Libertadores de América with 16.1 percent (5/31; CI95 percent= 5.5-33.7), Mariano Melgar with 15 percent (3/20; CI95 percent= 3.2-37.9) and Nuestra Señora de Guadalupe with 10.8 percent (4/37; CI95 percent= 3-25.4). No association was found between fascioliasis and nutritional anthropometric assessment or enteroparasite coinfection in children (p˃ 0.05). Conclusions: Fascioliasis was not found to affect the nutritional status of children. On the other hand, the clinical signs attributed to fascioliasis also correspond to the high presentation of enteric parasites(AU)

Prevalence of Intestinal Parasitic Infections and Associated Risk Factors among Pregnant Women Attending Prenatal Care in the Northwestern Ethiopia.

Intestinal parasitic infections (IPIs) are the common health problems in developing countries with low socioeconomic and poor living conditions. IPIs affect millions of pregnant women worldwide and may lead to adverse maternal and fetal effects. The present study was aimed at determining the prevalence and associated risk factors of IPIs among pregnant women in Ethiopia. A hospital-based cross-sectional study involving 384 pregnant women was conducted from November 2018 to March 2019. Relevant information on potential risk factors associated with IPIs was gathered using a semistructured questionnaire. Stool samples were collected and examined using wet mount and formol-ether concentration techniques. Logistic regression was used to evaluate the possible association between dependent and independent variables. The overall prevalence of IPIs was 36.7%. Seven species of parasites were identified. The most prevalent intestinal protozoan parasite identified was Entamoeba histolytica/dispar (9.6%) followed by Giardia intestinalis (8.9%). The predominant helminth parasite identified was Ascaris lumbricoides (8.6%), followed by hookworm (5.2%), Taenia spp. (3.6%), Strongyloides stercoralis (1.3%), and Schistosoma mansoni (1.04%). Six pregnant women (1.56%) had infection by two parasite species. The odds of IPIs were higher among illiterates (AOR = 4.63), lowest monthly income earners (AOR = 3.49), primigravida (pregnant for the first time) (AOR = 2.04), those who used unboiled well/stream/river water for drinking (AOR = 14.55), ate soil (AOR = 2.32), and consumed raw vegetables (AOR = 1.91). The prevalence of IPIs in the study subjects was substantially high. Thus, screening of the women for IPIs and providing health education during their antenatal care (ANC) visit are recommended to prevent possible adverse maternal and fetal effects resulting from these infections.

The Distribution of Intestinal Parasites in Patients Presenting to a University Hospital in Istanbul: A Seven-year Retrospective Analysis

Objective: The purpose of this study was to determine the intestinal parasite distributions in patients who applied to the Parasitology Laboratory of Istanbul University-Cerrahpasa, Cerrahpasa Medical Faculty, by evaluating the parasites retrospectively. Methods: Normal saline and stool lugol were applied for direct examination of stool samples that were sent for parasite examination; cellophane band samples were evaluated microscopically. The samples suspected to have protozoa were evaluated using modified acid fast and trichrome staining methods. We evaluated the parasitological examination results of patients who applied to our laboratory between January 2012 and December 2018. Results: A total of 2.96% of the 20,948 patients who applied had parasites in their faeces. Blastocystis spp. was detected at the highest rate (63.23%), followed by Giardia intestinalis (17.26%), Enterobius vermicularis (12.58%), Taenia saginata (2.42%), Cryptosporidium spp. (1.94%) and Entamoeba histolytica/dispar (1.45%). Conclusion: Although the prevalence of intestinal parasitic infections has decreased when compared to previous years, it still remains important. For this reason, solving infrastructure problems, providing information on personal hygiene and sanitation rules are among the most important tasks needed to reduce the prevalence of intestinal parasites.

The high prevalence of intestinal parasitic infections is associated with stunting among children aged 6-59 months in Boricha Woreda, Southern Ethiopia: a cross-sectional study.

BACKGROUND: Prior studies reported controversial results about the association between intestinal parasitic infections and childhood under-nutrition. We investigated the association of intestinal parasitic infections with under-nutrition among children aged 6-59 months in Boricha Woreda, Southern Ethiopia. METHODS: This community-based prospective cross-sectional study was carried out from January 1-30, 2019 among 622 children aged 6-59 months. A two-stage stratified sampling procedure was used. Data were collected using a structured, face-to-face interviewer-administered questionnaire and standard anthropometric measurements. The stool specimens were collected using standard technique and examined for the existence and species of intestinal parasites using direct wet mount, Kato Katz and staining technique. We have entered data using Epi Data 3.1 and WHO Anthro software and all analyses were conducted using SPSS version 20. The descriptive analyses were done to find descriptive measures for the socio-demographic and other important variables. Multivariable logistic regression analysis was used to identify factors associated with under-nutrition. Adjusted odds ratios (AORs) with a 95% confidence interval (CI) were computed to assess the presence and strength of associations. RESULTS: The total prevalence of intestinal parasitic infection was 48.7% (95% CI, 44.77-52.62). Approximately one-fourth (22%) of the children were infected with moderate intensity infections. Prevalence of stunting, underweight, wasting were 39.3, 24 and 11.6%, respectively. The prevalence of stunting among children infected with the intestinal parasite (59.4%) was significantly higher than the prevalence in non-infected children (20.6%) (p < 0.001). The absence of sanitation facility, living in medium and large family size, lack of shoes wearing practice, consuming raw vegetables and fruits were positively associated with intestinal parasitic infections. The presence of intestinal parasitic infections was positively associated with stunting (AOR = 2.18, 95% CI: 1.36-3.50) but not with wasting (AOR = 0.58, 95% CI: 0.3-1.13) and underweight (AOR: 0.92, 95% CI = 0.55-1.54). CONCLUSIONS: Under-nutrition and intestinal parasitic infections were serious public health concerns. Consolidating the prevailing water, sanitation and hygiene packages and routine deworming of children aged 6-59 months may aid to decrease the burden of both stunting and intestinal parasitic infection in children. Also, improving modern contraceptive methods utilization to reduce family size is recommended.

Protozoan infections are under-recognized in Swedish patients with gastrointestinal symptoms.

In acute gastroenteritis (GE), identification of the infectious agent is important for patient management and surveillance. The prevalence of GE caused by protozoa may be underestimated in Swedish patients. The purpose was to compare the prevalence of E. histolytica, Cryptosporidium spp., G. intestinalis, and C. cayetanensis in samples from patients where the clinician had requested testing for gastrointestinal parasites only (n = 758) to where testing for bacterial GE only (n = 803) or where both parasite and bacterial testing (n = 1259) was requested and a healthy control group (n = 197). This prospective cohort study was conducted in Region Jönköping County, Sweden (October 2018-March 2019). Fecal samples were analyzed with microscopy and real-time PCR. Cryptosporidium spp. was detected in 16 patients in the bacterial GE group and in 13 in the both bacterial and parasite group; no cases were detected in the group were only parasite infection was suspected. C. cayetanensis was detected in two patients in the bacterial GE group. One case of E. histolytica was detected in the bacterial group and one in the both bacterial and parasite group. G. intestinalis was detected in 14 patients in the parasite only group, 12 in the both parasite and bacterial group, three in the bacterial GE group, and one in the control group. Diarrhea caused by protozoa, especially Cryptosporidium was under-recognized by clinicians and is likely more common than hitherto estimated in Sweden. A more symptom-based diagnostic algorithm may increase detection and knowledge about protozoan infections.

Prevalence and Associated Factors of Soil-Transmitted Helminth Infections among Children Living with and without Open Defecation Practices in Northwest Ethiopia: A Comparative Cross-Sectional Study.

Soil-transmitted helminth (STH) infections cause devastating effect in human health. School-age children (SAC) account for the highest prevalence of STH infections in sub-Sahara. Open defecation practicing might be the major contributing factor, and creating an open defecation-free (ODF) declared community is also a big challenge. This study aimed to assess the prevalence of STH infections and associated factors among SAC in ODF declared and open defecation-practicing kebeles. A comparative cross-sectional study was conducted among 806 SAC from January 2019 to April 2019. Questionnaire-based data were collected using a structured questionnaire. Stool samples were collected and processed via the Kato-Katz technique. Prevalence and associated factors were computed with descriptive statistics and regression, respectively. Variables with a P-value < 0.05 were considered as significantly associated. This study revealed that the prevalence of STH infections in open defecation-practicing and ODF declared kebeles were 39.0% and 30.0%, respectively. Wearing open shoes, wearing shoes sometimes, and playing with soil were significantly associated (P < 0.01) with STH infections in ODF declared kebeles. Similarly, wearing shoes sometimes, not using latrine, and playing with soil were also significantly associated (P < 0.01) with STH infections in open defection-practicing kebeles. In conclusion, lower prevalence of STH infections was recorded in ODF declared than in open defection-practicing kebeles. Wearing shoes sometimes, playing with soil, and not using latrine were associated with STH infections. Therefore, creating an ODF environment and community awareness should be strengthened.

Prevalence of geophagy and knowledge about its health effects among native Sub-Saharan Africa, Caribbean and South America healthy adults living in France.

Geophagy is widespread among women from Sub-Saharan Africa, South America and the Caribbean and may persist in western countries. This practice may be associated with adverse effects such as anaemia, constipation or intestinal occlusion. We aimed to determine the prevalence of geophagy and the level of knowledge about its health effects among healthy adults originating from these countries and attending a travel medicine and international vaccination consultation in France. Among 101 travellers enrolled in the study, 83 (82.1%) were born in Sub-Saharan Africa and 13 (12.8%) in South America or the Caribbean. The mean duration of residence in France was 15.6 ± 10.4 years. Previous or current geophagy was present in 42 travellers [previous geophagy in 31 (30.7%) and current consumption in 11 (10.9%)]; 38 (90.5%) were women. The rate of awareness of harmful effects of geophagy as the risk of iron-deficient anaemia (18.8%) and soil-transmitted intestinal parasitic infections (11.9%) was low overall. Women with previous or current geophagy more often had history of iron therapy compared to those who never consumed, both during pregnancy (50.0 versus 14.3%; p = 0.0009) and outside pregnancy (47.4 versus 2.8%; p < 0.0001). Despite a long period of residence in France, geophagy was still a current practice among 10.9% of Sub-Saharan, South American and Caribbean travellers, who are poorly informed of its harmful effects. Therefore, specific information tailored to Sub-Saharan, South American and Caribbean about the risks of geophagy should be implemented in western countries.Level of evidence Level V, descriptive cross-sectional survey.

Intestinal parasites including Cryptosporidium, Cyclospora, Giardia, and Microsporidia, Entamoeba histolytica, Strongyloides, Schistosomiasis, and Echinococcus: Guidelines from the American Society of Transplantation Infectious Diseases Community of Practice.

These updated guidelines from the Infectious Diseases Community of Practice of the American Society of Transplantation review the diagnosis, prevention, and management of intestinal parasites in the pre- and post-transplant period. Intestinal parasites are prevalent in the developing regions of the world. With increasing travel to and from endemic regions, changing immigration patterns, and the expansion of transplant medicine in developing countries, they are increasingly recognized as a source of morbidity and mortality in solid-organ transplant recipients. Parasitic infections may be acquired from the donor allograft, from reactivation, or from de novo acquisition post-transplantation. Gastrointestinal multiplex assays have been developed; some of the panels include testing for Cryptosporidium, Cyclospora, Entamoeba histolytica, and Giardia, and the performance is comparable to conventional methods. A polymerase chain reaction test, not yet widely available, has also been developed to detect Strongyloides in stool samples. New recommendations have been developed to minimize the risk of Strongyloides donor-derived events. Deceased donors with epidemiological risk factors should be screened for Strongyloides and recipients treated if positive as soon as the results are available. New therapeutic agents and studies addressing the optimal treatment regimen for solid-organ transplant recipients are unmet needs.

Prevalence, Characteristics, Risk Factors, and Impact of Intestinal Parasitic Infections on School Children in Jeddah, Western Saudi Arabia.

Intestinal Parasitic Infections (IPIs) are a major public health problem worldwide, especially among children with a need for periodical evaluation of prevalence and risk factors to adopt an appropriate prevention strategy. This cross-sectional prospective study was conducted to identify prevalence, risk factors, characteristics, and impact of IPIs on school children in different regions of Jeddah, Saudi Arabia. Children were recruited from randomly selected schools. Questionnaires were distributed to students and filled by their parents to collect relevant information about sociodemographic, environmental, and hygienic living conditions. Stool samples and anthropometric measurements as indicators of nutritional status were collected from students who agreed to participate in the study. Fecal samples were examined by direct smear and formol-ether concentration method. Out of 581 collected stool samples, only 31 (5.3%) samples were positive for IPIs especially Blastocystis hominis (10 samples) and Giardia lamblia (six samples). The only two significant risk factors associated with IPIs were drinking water from tanks [odds ratio (OR): 3.35, 95% confidence interval (CI): 1.60-6.99, p = 0.001] and washing hands with only water (OR: 2.63, 95% CI: 1.17-5.93, p = 0.03). There was no significant impact of IPIs on growth parameters or level of children's academic performance.

[Access to drinking water, environmental protection and intestinal parasites in pediatric patients from the neighborhood El Codito in Bogotá, Colombia]. / Acceso a agua potable, protección ambiental y parasitismo intestinal infantil en El Codito. Bogotá, Colombia.

OBJECTIVE: To establish the correlation between intestinal parasitism in children younger than 6 years old and their dwelling in environmental protected areas without aqueduct service, in the neighborhood El Codito, in Bogotá, Colombia. MATERIALS AND METHODS: A cross-sectional study was done with 144 children between the ages of 4 and 70 months. Socio-demographic data were collected by surveying parents, and fecal samples were taken from the children to identify parasites. Descriptive measures were calculated for the variables by population type (parasitized and non-parasitized), establishing significant differences. Using a binary multivariate logistic regression, the correlation between intestinal parasitism and aqueduct was determined, adjusting the other studied variables. RESULTS: The prevalence of intestinal parasitism was 38.9%. The lack of aqueduct service was associated with intestinal parasitism (OR=31.25) after adjusting for other studied variables, which included affiliation to the subsidized health insurance regime compared with the contributory regime (OR= 1.49), home pets (OR= 2.58), mothers with professional jobs compared to mothers with non-professional jobs (OR=0.05), and dwelling in a rented room when compared with own dwelling (OR= 6.62). CONCLUSIONS: Children under the age of 6 living in protected areas without water service were more likely to suffer from intestinal parasitism. It is known that preserving protected areas to protect the environment is of great importance, but if the settlement of populations in these territories is not prevented in time, the population living there is subject to adverse conditions which violate human dignity.

OBJETIVOS: Establecer la relación entre parasitismo intestinal en niños menores de 6 años y vivienda en áreas de protección ambiental, sin servicio de acueducto, en El Codito -Bogotá, Colombia. MÉTODOS: Estudio de corte transversal que incluyó 144 niños entre los 4 y 70 meses de edad. Se recolectaron datos sociodemográficos encuestando a los padres y se tomaron muestras fecales de los niños. Se calcularon medidas descriptivas de las variables por tipo de población (parasitada y no parasitada) estableciendo diferencias estadísticamente significativas. Utilizando una regresión logística binomial multivariada se determinó la relación entre parasitismo intestinal y servicio de acueducto, controlando por las demás variables estudiadas. RESULTADOS: Se encontró una prevalencia de parasitismo intestinal de 38,9%. La falta de servicio de acueducto estuvo asociada a parasitismo (OR=31,25) ajustando por las demás variables estudiadas. Otras variables asociadas a parasitismo fueron: afiliación al régimen de salud subsidiado al compararla con el contributivo (OR=1,49), presencia de animales en la vivienda (OR=2,58), madres con oficio técnico-profesional al compararlas con madres con oficios no calificados (OR=0,05) y vivienda en habitación rentada al compararla con vivienda propia (OR=6,62). CONCLUSIONES: Los niños menores de 6 años viviendo en áreas protegidas sin servicio de acueducto presentaron con mayor frecuencia parasitismo intestinal. Si bien es claro que el establecimiento de áreas protegidas para preservar el medio ambiente es esencial, si no se previene el asentamiento de poblaciones en estos territorios a tiempo, la población que habita en los mismos está sujeta a condiciones adversas que atentan contra la dignidad humana.

Undernutrition, intestinal parasitic infection and associated risk factors among selected primary school children in Bahir Dar, Ethiopia.

BACKGROUND: Monitoring of undernutrition and parasitic infection are essential to design appropriate intervention strategies. The aim of this study was to assess the prevalence of undernutrition, intestinal parasitic infection and their associated risk factors among school children in Bahir Dar, Ethiopia. METHODS: A school-based cross-sectional survey was conducted from February to June 2014 among 382 students selected from primary schools in Bahir Dar. The study subjects were selected by a systematic random sampling method. Sociodemographic data from students and their family/guardians were obtained using structured questionnaire. Height and weight of the students were measured using a standard calibrated balance. Fresh fecal samples were collected and processed using formalin-ether concentration technique. The data were analyzed using SPSS version 20.0 statistical software. RESULTS: The overall prevalence of undernutrition was 41.6% (18.3% stunted, 26.7% thinness and 25.9% underweight). Meal frequency ≤ 3 times a day (AOR=4.11; 95% CI: 2.23-7.59) and family monthly income <500 birr (AOR=5.87; 95% CI: 2.61-13.23) were important predictors of undernutrition. The risk of stunting was increased among students with meal frequency ≤ 3 times a day (AOR=5.56; 95% CI: 2.97-10.41) and age ranges from 9-10 years (AOR=3.02; 95% CI: 1.41-6.47). The odds of thinness was significantly increased among students with parasitic infection (AOR=1.92; 95% CI: 1.15-3.19) and family monthly income <1500 birr (AOR=2.69; 95% CI: 1.16-6.26). The likelihood of being underweight was increased among students infected with intestinal parasites (AOR=2.43; 95% CI: 1.40-4.22). The overall prevalence of intestinal parasitosis was 52.4%. The risk of parasitic infection was significantly increased among students with unclean fingernails (AOR=4.96; 95% CI: 2.79-8.82) and irregular hand washing habit (AOR=8.05; 95% CI: 4.66-13.89). CONCLUSIONS: This study revealed that undernutrition and intestinal parasitic infection were public health problems among school children in the study areas. These results highlight the importance for integrated efforts to address undernutrition and parasitic infection.

Enteroparasitosis infections among renal transplant recipients in Khartoum state, Sudan 2012-2013.

OBJECTIVES: Renal transplantation procedure markedly increased over the past few decades. The risk of harboring parasitic diseases may affect transplant recipients during life expectancy. We aimed in this study to determine the enteroparasitosis frequency among renal transplant recipients in Khartoum state, Sudan. A case-control hospital-based study performed between November 2012 and May 2013, on 300 renal transplant recipients attending Sudanese Kidney Association hospital in Khartoum state, Sudan, along with 300 normal healthy individuals matching the case in age and sex. Stool samples were collected for parasitological studies. RESULTS: Out of the 300 renal transplant recipients: 242 (80.7%) were males mean age 43 ± 11.28 and 58 (19.3%) were females mean age 41 ± 13.41. Intestinal parasitic infection was observed in 118 participants and the overall frequency was 19.7%; of which 64 were cases (21.3%) and 54 (18.0%) were controls. Eight different species of intestinal parasites were identified; Entamoeba histolytica/dispar (7.5%), Entamoeba coli (6.5%), Giardia lambelia (3.2%), Cryptosporidium parvum (1.2%), Ascaris lumbricoides (0.6%), Enterobius vermicularis (0.3%), (0.2%) for each of Strongyloides stercoralis and Hymenolepis nana.

Prevalence of Opportunistic Intestinal Parasites and Associated Factors among HIV Patients while Receiving ART at Arba Minch Hospital in Southern Ethiopia: A Cross-sectional Study.

BACKGROUND: Opportunistic Intestinal Parasites (OIPs) commonly cause morbidity in HIV/AIDS patients due to the decline of CD4+T-cells. The burden of Opportunistic Intestinal Parasitic Infections (OIPIs) in Ethiopia is expected to be high due to poor sanitation and co-pandemicity of HIV/AIDs. Therefore, frequent assessment of the magnitude and associated factors for intestinal parasitosis is essential for the management of HIV/AIDS patients. METHODS: A hospital based cross-sectional study was conducted among patients attending Arba Minch Hospital Antiretroviral Therapy (ART) Clinic from March to June 2016. Stool specimens were processed for parasitological examination using direct wet mount, formol-ether sedimentation and modified Ziehl-Neelsen staining techniques. CD4+ T-cell count data were taken from patients' medical records. A structured questionnaire was used to collect data on socio-demographic characteristics and possible associated factors for OIPIs. All the data were analyzed using SPSS version 20. RESULTS: Two hundred and twenty ART patients participated in the study. The overall prevalence of intestinal parasitic infections was 28.18% while that of OIPIs alone was 17.72%. Among identified intestinal parasites, Cryptosporidium species accounts for the highest frequency (19/220, 8.63%), followed by Cyclospora species (13/220, 5.90%). Presence of domestic animals (AOR=2.07, 95%CI:1.07-8.40, P= 0.032) and CD4+ T-cell count <500cell/µl (AOR=4.66, 95%CI:1.17-5.35, P= 0.001) were significantly associated with OIPIs. CONCLUSION: The study indicated that co-infection rate of OIPs is high among ART patients. It also found that contact with domestic animals and having CD4+ count <500 cell/µl predict for the presence of OIPs.

Introduction: the infections caused by intestinal parasitism are considered a health problem because of their high prevalence rates. Child population is the most affected one. The community "Pepita de Oro" does not scape this reality. Objective: to evaluate hygienic habits and knowledge on intestinal parasitism in 1-9 years-old in that community. Materials and methods: An observational, correlational and cross-sectional study was carried out in the urban marginal community "Pepita de Oro" from the city Tena, in the Ecuadorian Amazonia, in the period from August 2015 to September 2016. 50 family fathers applied a survey and coproparasitical tests were made to their 50 children, after obtaining the previous consent. The following variables were worked out: sex, age, kind of parasitism, water supply, water treatment, hygienic conditions, knowledge on intestinal parasitism and hygienic norms. Results: it was found that the habit of washing hands before eating was high, 94 %; washing hands after going to the toilet was 88 %. According to the results of the coproparasitical tests, the highest percent of children was found poliparasitized, with 77 % and 23 % were monoparasitized. The age group that was most affected by mono-parasitism was the 5-9 years-old group, with 18 %, while the 1-4 years-old group was the most affected with poliparasitism. 60 % was evaluated with parasitism and lack of knowledge on the different hygienic norms. Conclusions: hygienic habits knowledge and practice were poor and there is a prevalence of parasitism (AU).

The community "Pepita de Oro" does not scape this reality. Objective: to evaluate hygienic habits and knowledge on intestinal parasitism in 1-9 years-old in that community. Materials and methods: An observational, correlational and cross-sectional study was carried out in the urban marginal community "Pepita de Oro" from the city Tena, in the Ecuadorian Amazonia, in the period from August 2015 to September 2016. 50 family fathers applied a survey and coproparasitical tests were made to their 50 children, after obtaining the previous consent. The following variables were worked out: sex, age, kind of parasitism, water supply, water treatment, hygienic conditions, knowledge on intestinal parasitism and hygienic norms. Results: it was found that the habit of washing hands before eating was high, 94 %; washing hands after going to the toilet was 88 %. According to the results of the coproparasitical tests, the highest percent of children was found poliparasitized, with 77 % and 23 % were monoparasitized. The age group that was most affected by mono-parasitism was the 5-9 years-old group, with 18 %, while the 1-4 years-old group was the most affected with poliparasitism. 60 % was evaluated with parasitism and lack of knowledge on the different hygienic norms. Conclusions: hygienic habits knowledge and practice were poor and there is a prevalence of parasitism (AU).

Prevalence of Intestinal Parasites and Associated Risk Factors for Infection among Rural Communities of Chachoengsao Province, Thailand.

Intestinal parasitic infections remain a major public health problem in many parts of Thailand, particularly in rural areas. This study aimed to determine the prevalence of intestinal parasitic infections and associated risk factors among the people living in Huai Sai sub-district, Bang Khla district, Chachoengsao Province, central Thailand. A cross-sectional survey was carried out from June 2017 to August 2017 which included a total of 224 participants. Stool samples were examined using a simple direct smear and formalin ethyl acetate concentration technique. Association between risk factors and intestinal parasitic infections was assessed using multivariate logistic regression analysis. The overall prevalence of intestinal parasitic infections was 16.1%. Soil-transmitted helminth infections (14.3%) were more common than protozoan infections (1.8%). The most common intestinal parasites were hookworms (6.7%) followed by Strongyloides stercoralis, (5.0%), Ascaris lumbricoides (1.3%) and Trichuris trichiura (1.3%). Entamoeba histolytica/dispar (1.0%), Giardia intestinalis (0.4%), and Blastocystis hominis (0.4%) were the protozoans identified. A high prevalence of infections was found in male participants of ≥40 years who raised dogs in the households and did not wear boots while working fields. Multivariate analysis showed a significant association of intestinal parasitic infections with gender with the adjusted odds ratio (OR) of 2.4 and 95% confidence interval (CI) of 1.1-5.2 (P=0.020). The results showed a high prevalence of soil-transmitted helminth infections among adults in rural communities which were particularly apparent regarding the skin-penetrating species of nematodes. A greater focus on intervention is required by improving sanitation and personal hygiene to prevent the spread of intestinal parasitic infections.

Intestinal Parasitic Infections and Environmental Water Contamination in a Rural Village of Northern Lao PDR.

A field survey studying intestinal parasites in humans and microbial pathogen contamination at environment was performed in a Laotian rural village to identify potential risks for disease outbreaks. A parasitological investigation was conducted in Ban Lak Sip village, Luang Prabang, Lao PDR involving fecal samples from 305 inhabitants as well as water samples taken from 3 sites of the local stream. Water analysis indicated the presence of several enteric pathogens, i.e., Aeromonas spp., Vibrio spp., E. coli H7, E. coli O157: H7, verocytotoxin-producing E. coli (VTEC), Shigella spp., and enteric adenovirus. The level of microbial pathogens contamination was associated with human activity, with greater levels of contamination found at the downstream site compared to the site at the village and upstream, respectively. Regarding intestinal parasites, the prevalence of helminth and protozoan infections were 68.9% and 27.2%, respectively. Eight helminth taxa were identified in fecal samples, i.e., 2 tapeworm species (Taenia sp. and Hymenolepis diminuta), 1 trematode (Opisthorchis sp.), and 5 nematodes (Ascaris lumbricoides, Trichuris trichiura, Strongyloides stercoralis, trichostrongylids, and hookworms). Six species of intestinal protists were identified, i.e., Blastocystis hominis, Cyclospora spp., Endolimax nana, Entamoeba histolytica/E. dispar, Entamoeba coli, and Giardia lamblia. Questionnaires and interviews were also conducted to determine risk factors of infection. These analyses together with a prevailing infection level suggested that most of villagers were exposed to parasites in a similar degree due to limited socio-economic differences and sharing of similar practices. Limited access to effective public health facilities is also a significant contributing factor.

Parásitos e inmigración: ¿cuál es la mejor actitud? / Parasites and immigration: what is the best approach?

El aumento de la población inmigrante en Europa (en España se considera que supone, en este momento, el 10% de la población total) conlleva un incremento en la prevalencia de determinadas enfermedades, en especial enfermedades infecciosas, y obliga a enfocar el estudio de los pacientes teniendo muy en cuenta las enfermedades prevalentes en su zona de origen. Diferentes organismos defienden el cribado sistemático, o el tratamiento empírico indiscriminado. El cribado debe incluir, al menos, un estudio coproparasitológico, de hemoparásitos y de parásitos urinarios. El estudio coproparasitológico es esencial, dada la alta prevalencia de parásitos intestinales en población procedente de áreas tropicales y subtropicales. La búsqueda de hemoparásitos es fundamental para la detección de Plasmodium, Babesia, Trypanosoma y también de algunas filarias. En individuos asintomáticos procedentes de zonas endémicas para Plasmodium es primordial la introducción de técnicas moleculares, dada la baja sensibilidad del resto. Todo individuo procedente de áreas endémicas para filariasis o enfermedad de Chagas debe ser sometido al cribado de estas. El cribado de Trypanosoma cruzi es de especial relevancia en embarazadas y donantes de sangre y de órganos. Se revisan los agentes etiológicos a tener en cuenta en población inmigrante ante un síndrome febril, cardiovascular, respiratorio, digestivo, hepatoesplenomegalia, síndromes nefrourológicos, neurológicos, reumatológicos, oftalmológicos, otorrinolaringológicos y cutáneos (AU)

The increasing immigrant population in Europe (in Spain it is assumed to account for 10% of the total population) is leading to a higher prevalence of some diseases, especially infectious diseases. When studying these patients, the most prevalent diseases in their area of origin must be taken into account. Different agencies advocate systematic screening, or indiscriminate empirical treatment. Screening should include a search for parasites in stool, blood and urine samples. Stool parasitological studies are fundamental, given the high prevalence of intestinal parasites in populations from tropical and subtropical areas. The search for blood parasites is essential for the detection of Plasmodium, Babesia, Trypanosoma and also some filaria. In asymptomatic individuals coming from areas endemic for Plasmodium, the use of molecular techniques is necessary, given the low sensitivity of conventional methods. All individuals from areas endemic for filariasis or Chagas disease should be screened. Screening for Trypanosoma cruzi is particularly important in pregnant women and blood and organ donors. We review the main agents to be considered in immigrant patients showing febrile, cardiovascular, respiratory or gastrointestinal syndromes, hepatosplenomegaly, and nephro-urological, neurological, rheumatologic, ophthalmological, ear, nose and throat (ENT) and cutaneous síndromes (AU)

Infections in patients affected by liver cirrhosis: an update.

Patients with liver cirrhosis present an increased incidence of infections. The main cause has been founded in alterations of the enteric flora and of the intestinal barrier probably due to portal hypertension, in addition to a reticulo-endothelial system dysfunction. Furthermore, those living with cirrhosis can report a high predisposition to sepsis and septic shock, due to the excessive response of pro-inflammatory cytokines and a complessive hemodynamic derangement. By the analysis in the experimental model of the cirrhotic rat, it was demonstrated that radio-labelled Escherichia coli given by the oral route resulted in the location of the bacteria in the gut, the ascitic fluid and mesenteric lymph nodes, a phenomenon known as bacterial translocation. Bacteria encountered with the highest frequency are those colonizing the intestinal tract, such as E. coli, Klebsiella pneumoniae and Enterobacteriaceae, intracellular bacteria and parasites are reported with a lower frequency. Multi-drug resistant bacteria are cultured with the highest frequency in those with frequent hospitalisations and report both high septic shock and mortality rates. Spontaneous bacterial peritonitis (SBP) is the commonest infection in cirrhotic, estimated to occur in 10-30% of the cases with ascites. A practical approach may include administration of a protected penicillin, III generation cephalosporin or quinolones in uncomplicated cases. Instead, in complicated cases and in nosocomial SBP, administration of cephalosporin or quinolones can be burned by the high resistance rate and drugs active against ESBL-producing bacteria and multi-drug resistant Gram positive bacteria have to be considered as empiric therapy, until cultures are available. When cultures are not readily available and patients fail to improve a repeated diagnostic paracentesis should be performed. Current investigations suggest that norfloxacin 400 mg/day orally has been reported to successfully prevent SBP in patients with low-protein ascites and patients with prior SBP.

Prevalence and risk factors of intestinal protozoan infections: a population-based study in rural areas of Boyer-Ahmad district, Southwestern Iran.

BACKGROUND: Parasitic infections are still a significant health problem in rural areas in developing countries including Iran. There is no recent population-based data about the prevalence of human intestinal parasites in most rural areas of Iran. The current study aimed to determine the prevalence of intestinal protozoan infection in inhabitants of rural areas of Boyer-Ahmad district, Southwestern Iran. METHODS: A total of 1025 stool samples were collected from the inhabitant of 50 randomly selected villages in Boyer-Ahmad Township. The stool samples were evaluated by parasitological methods including, direct wet-mounting, formalin ethyl acetate concentration, zinc sulfate floatation, and Trichrome permanent stain for detection of protozoan infections. Diarrheic samples were further evaluated with a modified Ziehl-Neelsen staining method for detection of coccidian parasites. RESULTS: The prevalence of both pathogenic and nonpathogenic intestinal parasites in the population was 37.5% (385 out of 1025 cases), some individual with multiple infections. Giardia lamblia was detected in 179 (17.46%), Blastocystis hominis in 182 (17.76%), Entamoeba histolytica/dispar in 9 (0.87%), Endolimax nana in 216 (21.07%), Entamoeba coli in 151 (14.73%), Ioedamoeba butschlii in 45 (4.39%), Chillomastix mesnili in 22 (2.14%), Trichomonas hominis in 2 (0.19%) and Dientamoeba fragillis in 2 (0.19%) of cases. Multivariate logistic regression revealed significant associations between protozoan infection (pathogenic protozoa) and contact with animals (OR yes/no = 2.22, p < 0.001) and educational status (OR higher/illiterate = 0.40, P = 0.01). CONCLUSION: Findings of this study demonstrated that protozoan infection rate in rural areas of southwestern Iran is still high and remained as a challenging health problem in these areas.
