RESUMO

Abstract In Colombia, the prevalence of intestinal parasitosis varies throughout its regions, social classes, and living conditions. We performed a cohort study (2017-2018) on children from 1-10 years old in El Cedro, Ayapel, Colombia. We tested a convenience sampling of those who accepted and signed the consent form. The National Intestinal Parasite Survey was applied; feces and water source sampling were tested for coprological and microbiology analysis, respectively. Education and pharmacologic treatment to the minor and co-inhabitants were performed. After the recruiting, we followed up at 7 and 12 months. Statistical analysis was performed using IBM® SPSS22. Participants 47, 61,7% male, average age 5,7 years. The caretakers had a low educational background. The monthly income of 72,3% of households was < USD 87. The coprological test showed 61,7% with at least one type of parasite; 32,2% with two or more. Trichuris trichiura was the most frequent. Water sources were positive for Escherichia coli. The population tested showed a high frequency of parasitic infection. We did not find a reduction of intestinal parasitosis with educa tion and pharmacologic treatment at the end of the follow-up. It must be necessary to impact social determinants of public health to achieve intestinal parasitosis control.


Resumen En Colombia, la prevalencia de parasitosis intestinal varía por regiones, clases sociales, condiciones de vida. Realizamos estudio de cohorte (2017-2018) en niños de 1-10 años en El Cedro, Ayapel, Colombia. Muestra por conveniencia, se incluyeron aquellos que aceptaron y firmaron el consentimiento. Se aplicó la Encuesta Nacional de Parásitos Intestinales; se analizaron muestras de heces y fuentes de agua para análisis coprológico y microbiológico, respectivamente. Se realizó educación y tratamiento farmacológico al menor y cohabitantes. Después del reclutamiento, seguimiento a los 7 y 12 meses. El análisis estadístico se realizó con IBM® SPSS22. Participantes 47, 61,7% hombres, promedio de edad 5,7 años. Cuidadores con bajo nivel educativo, ingreso mensual del 72,3% de los hogares fue <USD 87. La población analizada mostró una alta frecuencia de infección parasitaria, un 61,7% con al menos un tipo de parásito; 32,2% con dos o más. Trichuris trichiura fue el más frecuente. Las fuentes de agua fueron positivas para Escherichia coli. Al final del seguimiento, no se redujo la frecuencia de la parasitosis intestinal a pesar de educación y tratamiento farmacológico. Se requiere incidir en los determinantes sociales y de salud pública para lograr el control de las parasitosis intestinales.

RESUMO

Parasitic infections (PIs) are among the most frequent infectious diseases globally. Previous studies reported discrepant results regarding the prevalence of PIs in internationally adopted children (IAC). Data from IAC referred to our paediatric university hospital in 2009-2021 were collected to evaluate the frequency of PIs by the use of stool microscopic examination, antigen assays for Giardia lamblia and Cryptosporidium parvum, and serological tests for Toxocara canis, Strongyloides stercoralis, Schistosoma mansoni, Echinococcus spp., Taenia solium, and Trypanosoma cruzi. Uni- and multivariate logistic regression analyses were performed to evaluate risk factors for PIs and eosinophilia. The proportion of IAC with at least one positive test was 26.83% (640/2385); 2.13% (n = 51) had positive tests for 2 or 3 parasites. A positive assay for helminthic infection was retrieved in 11.07% of children (n = 264), and 17.86% (n = 426) presented with eosinophilia. The most common positive tests were anti-Toxocara canis antibodies (n = 312; 13.8%), followed by positive stool antigen for Giardia lamblia (n = 290; 12.16%), and positive microscopic stool examination for Blastocystis hominis (n = 76; 3.19%). A statistically significant association was found between PIs and region of origin (children from Latin America and Africa were more likely to present PIs than children from Eastern Europe), age 5-14 years, and eosinophilia. No significant association was observed between PIs and gender, vitamin D deficiency, or anemia. In conclusion, PIs are relevant in IAC and an accurate protocol is needed to evaluate IAC once they arrive in their adoptive country.

RESUMO

Tapeworms of zoonotic importance have been described as a leading public health problem. Current research was aim to assess the prevalence of tapeworms among 5-12years school children residing in district Lower Dir, Pakistan from January 2019-December 2019. The wet mount preparation in saline/iodine/methods were used for stool examination. Data was analyzed using appropriate descriptive, static methods. Of the 400 children studied 71.7% were infected with one or more species of intestinal parasites. Single infection of cestode species was found in 69 individuals with 17.2% prevalence and multiple parasitic infections were identified in 19.7% (n=79/400) individuals. The multiple infection were comprised as 10% (n=40) double, 6.75% (n=27) triple and 3% (n=12) quadruple. A total of 9 species of helminths and one species of protozoan infection. Among the helminths Ascaris lumbricoides was the most prevalent 33.1% (n=95), Taenia saginata 22.6% (n=65), hookworm 19.8% (n=57), Hymenolepis nana 18.8% (n=54), Enterobius vermicularis and Hymenolepis diminuta 1.39% (n=4each), Trichuris trichura 1.04% (n=3), Toxocara spp 0.69% (n=2) and Schistosoma japonicum 0.34% (n=1) were reported. One protozoan species was Cryptosporidium spp 0.69% (n=2) in current study. In case of A.lumbricoides, hookworm, E.vermicularis, T.trichura, T.saginata, H.nana and H.diminuta the male children of below 8 years of age were highly infected. Other infections are reported in the same prevalence with slight difference if any. We conclude that there is a need for mass scale campaigns to create awareness regarding health and hygiene in children and the need for development of effective poverty control programs because deworming alone is not adequate to control parasitic infections.(AU)


As tênias de importância zoonótica têm sido descritas como um dos principais problemas de saúde pública. A pesquisa atual teve como objetivo avaliar a prevalência de tênias entre crianças em idade escolar de 5 a 12 anos que residem no distrito de Lower Dir, Paquistão, de janeiro de 2019 a dezembro de 2019. Os métodos de preparação para montagem úmida em solução salina/iodo foram usados para exame de fezes. Os dados foram analisados usando métodos descritivos e estáticos apropriados. Das 400 crianças estudadas, 71,7% estavam infectadas com uma ou mais espécies de parasitas intestinais. Infecção única de espécies de cestóides foi encontrada em 69 indivíduos com prevalência de 17,2% e infecções parasitárias múltiplas foram identificadas em 19,7% (n = 79/400) indivíduos. As infecções múltiplas foram compostas por 10% (n = 40) dupla, 6,75% (n = 27) tripla e 3% (n = 12) quádrupla. Um total de 9 espécies de helmintos e uma espécie de infecção por protozoários. Entre os helmintos, Ascaris lumbricoides foi o mais prevalente 33,1% (n = 95), Taenia saginata 22,6% (n = 65), ancilóstomo 19,8% (n = 57), Hymenolepis nana 18,8% (n = 54), Enterobius vermicularis e Hymenolepis diminuta 1,39% (n = 4cada), Trichuris trichura 1,04% (n = 3), Toxocara spp 0,69% (n = 2) e Schistosoma japonicum 0,34% (n = 1). Uma espécie de protozoário foi Cryptosporidium spp 0,69% (n = 2) no estudo atual. No caso de A. lumbricoides, ancilostomíase, E. vermicularis, T. trichura, T. saginata, H. nana e H. diminuta, as crianças do sexo masculino com menos de 8 anos de idade estavam altamente infectadas. Outras infecções são relatadas na mesma prevalência, com ligeira diferença, se houver. Concluímos que há uma necessidade de campanhas em massa para criar consciência sobre saúde e higiene em crianças e a necessidade de desenvolvimento de programas eficazes de controle da pobreza, porque a desparasitação por si só não é adequada para controlar infecções parasitárias.(AU)

RESUMO

Background: Haw's syndrome results in bilateral projection of the third eyelid, which is caused by a dysfunction of the sympathetic innervation in the region, not accompanied by other ocular changes. It has been mostly seen in cats, under 2-year-old and, it usually shows an acute presentation. It is believed that the disorder may be self-limiting, but several infectious etiologies have been proposed, together with diarrhea. The aim of the study was to report a case of a 2-year-old mixed breed male feline, castrated and diagnosed with Haw's syndrome, associated with an infectious condition given the presence of Giardia sp. Case: A 2-year-old male, mixed-breed cat and orchiectomized, was admitted and treated at the Veterinary Hospital of the Federal University of Jataí. In the anamnesis, the owner complained that the cat had had pasty brown diarrhea for 4 days and a projection of the third eyelid. He emphasized that the animal used to have some episodes of diarrhea sporadically and the last deworming was carried out 3 months ago from that day. He reported contact with other random street and outdoor cats. On the physical examination, bilateral projection of the third eyelid was observed without any other visible alteration. The third eyelid projection was responsive to the mydriatic and adrenergic [phenylephrine 10%] eye drops instillation test. Complete blood count and serum biochemical evaluation of creatinine, alkaline phosphatase (ALP) and alanine aminotransferase (ALT) concentrations were performed. In addition, abdominal ultrasound and parasitological examination of feces were requested. Complete blood count showed eosinophilia and serum biochemical evaluations were within reference values. The coproparasitological examination detected Giardia sp. On the ultrasound, no significant changes were observed. The recommended treatment was anthelmintic [fenbendazole 50 mg/kg, SID, for 5 days]. However, one week later, the coproparasitological examination still showed Giardia sp. Given this scenario, the chosen treatment was the use of nitazoxanide [25 mg/kg, BID, for 7 days]. Therefore, the patient presented emesis and the treatment with nitazoxanide had to be suspended. Thus, metronidazole [25 mg/kg, BID, for 7 days] was prescribed, in addition to the environmental disinfection and daily litter box cleaning, all performed with quaternary ammonia. After 1 week of treatment with metronidazole, the patient's clinical improvement and reversal of the third eyelid projection were observed. Discussion: This case proved to be consistent with the data found in the literature, in which cats younger than 2-year-old are affected by Haw's syndrome and may present concomitant diarrhea. On the physical examination, the parameters evaluated were within normal reference for the cat species and the bilateral projection of the third eyelid was the only alteration found in the patient. The prognosis for the patient with Haw's syndrome and concomitant giardiasis is favorable, as long as the intestinal infection is treated briefly, in order to prevent the chronicity of the enteroparasitosis. The need of more studies is evident in order to explain the Haw's syndrome pathology and so, clarify the real cause of this disease. Since the syndrome is mostly, a self-limiting disease, interventions with topical ocular drugs are not necessary. However, in the event of a concomitant disease, infection or underlying cause, it must be treated correctly. Attention is drawn to the need of feces examination through coproparasitological evaluation in cases of diarrhea.

RESUMO

PURPOSE: To study intestinal parasitosis and its association with viral load and CD4+ T cell count in HIV-infected individuals at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia. METHODS: A cross-sectional study was conducted from March to June 2019. Three hundred and sixteen study participants were selected using systematic random sampling technique. Sociodemographic and clinical data were collected using structured questionnaire. Stool samples were collected and examined using direct saline, formol ether concentration technique and modified acid fast staining. CD4+ T cell counts and viral load were determined by fluorescence-activated cell sorting (BD FACS) and COBAS Ampliprep/COBAS TaqMan HI2CAP assay, respectively. Data were entered into Epi Data 3.1 and transferred to SPSS version 20 software for analysis. Bivariable and multivariable analyses were performed using a binary logistic regression model. P values of less than 0.05 were considered statistically significant. RESULTS: The overall prevalence of intestinal parasitosis was 24.7% (78/316). The most commonly detected parasite was Cryptosporidium species with 5.4% (17/316), followed by Ascaris lumbricoides with 5.1% (16/316). There was a significant association with low CD4+ T cell count (AOR: 3.207; 95% CI: 1.237, 8.317), high viral load (AOR: 2.933; 95% CI: 1.326, 6.489), individuals aged 31-40 years (AOR: 0.305; 95% CI: 0.124, 0.751) and individuals aged 41-50 years (AOR: 0.261; 95% CI: 0.101, 0.671). CONCLUSION: In this study, prevalence of intestinal parasitic infections was high and was associated with low CD4+ T cell count and high viral load. Therefore, screening of HIV patients, especially those with low CD4+ T-cell count and high viral load, particularly for opportunistic intestinal parasitic infections would be of utmost importance in the efforts to prevent and control opportunistic infections in HIV patients.

RESUMO

This study was sought to determine the impact of CD4+ T-cell count and associated risk factors with intestinal parasitosis in people living with HIV (PLHIV) in Central Hospital, Auchi, Edo State, Nigeria. One hundred and seventy (170) HIV-seropositive subjects were enrolled in the study from 24 August 2015 to 22 January 2016. Sociodemographic data were assessed using structured questionnaires. Blood and stool samples were collected from every participant. CD4+ T-cell count and stool parasitology were performed. The prevalence of intestinal parasites was 44.7%. Helminthiasis (67%) was a predominant infection in the study, while 32.9% had protozoasis. Specifically, Ancylostoma duodenale (33.3%) was the most common helminth, and Trichuris trichiura (7.8%), the least. However, Strongyloides stercoralis, Ascaris lumbricoides and Hymenolepis nana were 13.7%, 31.5% and 13.7%, respectively. Cryptosporidium spp. (25.0%) was the only protozoan. Lower CD4+ T-cell count, ART naivety (OR = 2.62 p < 0.05), residence in a rural setting (OR = 0.89, p < 0.05), and farming occupation (OR = 1.70, p < 0.05) were associated with the prevalence of intestinal parasitosis among PLHIV. This study revealed a significantly high prevalence of intestinal parasitosis in ART naive PLHIV with reduced CD4+ count. Hence, it is recommended to frequently test for intestinal parasitosis and commencement of ART in all PLHIV to improve their health and longevity.

RESUMO

BACKGROUND: Intestinal parasitosis is one of the commonly perceived serious problems often observed in children leading to high mortality. The objective of the study was to identify the intestinal parasites and study their prevalence in the two mostly disadvantaged communities (Musahar and Chepang) of Nepal. METHODS: This was a cross-sectional study conducted in the Musahar and Chepang communities of Nepal from April to October 2019. A total of 205 random stool samples were collected in dry, clean and screw-capped plastic containers and mixed with 2.5% potassium dichromate solution. A pre-structured questionnaire was used to collect data on predisposing factors. The laboratory examination of the stool samples was done by direct microscopy and further confirmed by concentration methods (formalin ether sedimentation technique and flotation technique using Sheather's sugar solution), and modified acid-fast staining. Detection of eggs of Enterobius vermicularis was done by cellophane tape method. RESULTS: The overall prevalence of intestinal parasitic infection was found to be 36.6%, with a similar prevalence in the Chepangs (39.8%) and in the Musahars (33.3%) (P > 0.05). The most predominant helminth was Ascaris lumbricoides (15.6%), while the most prevalent protozoan was Entamoeba histolytica/dispar (5.4%). The study also assessed a significant association between the prevalence of parasites with socio-demographic factors, types of drinking water consumption and sanitation habits of the people (P < 0.05). CONCLUSION: The findings of the study suggest a need for formulating effective preventive and control strategies against intestinal parasitic infections along with the continuity of mass deworming program.

RESUMO

El objetivo de la presente investigación fue determinar la prevalencia de parásitos intestinales en niños preescolares usuarios de 12 Centros de Educación Inicial Simoncito (CEIS) del municipio Angostura del Orinoco, estado Bolívar, Venezuela. Se estudiaron las heces de 515 niños de ambos géneros (2 a 5 años), mediante la técnica de sedimentación espontánea. La prevalencia de enteroparásitos fue de 39,4% (n=203). No hubo diferencias estadísticamente significativas (χ2 = 1,59 g.l.: 2 p> 0,05) respecto a la edad, pero si según el género (p<0,05), resultando los niños varones más afectados con 46,9%. Se identificaron 11 taxones de enteroparásitos, destacando el cromista Blastocystis spp. con 27,4% (n=141) y el protozoario Giardia intestinalis con 13,2% (n=68). Se encontró una baja prevalencia de helmintos, donde Ascaris lumbricoides fue el más común con 1,6% (n=8). De los 203 niños parasitados, el 70,9% (n=144) estaba monoparasitado y 29,1% (n=59) poliparasitado. Los principales parásitos asociados fueron Blastocystis spp. (89,8%), G. intestinalis (44,1%) y Endolimax nana (35,3%). En conclusión, se determinó una elevada prevalencia de parásitos intestinales en la población estudiada, por lo que estas infecciones continúan siendo un problema de salud pública en niños de Ciudad Bolívar, Venezuela


The objective of the present investigation was to determine the prevalence of intestinal parasites in preschool children users of 12 Simoncito Initial Education Centers (CEIS) of the Angostura del Orinoco municipality, Bolívar state, Venezuela. The feces of 515 children of both genders (2 to 5 years old) were studied using the spontaneous sedimentation technique. The prevalence of enteroparasites was 39.4% (n = 203). There were no statistically significant differences (χ2 = 1.59 d.f .: 2 p> 0.05) with respect to age but if according to gender (p <0.05), because the most affected were male child with 46.9%. Eleven taxa of enteroparasites were identified, highlighting the chromist Blastocystis spp. (27.4%) and the protozoan Giardia intestinalis (13.2%). A low prevalence of helminths was found, where Ascaris lumbricoides was the most common with 1.6%. Of the 203 parasitized children, 70.9% (n = 144) were monoparasitized and 29.1% (n = 59) polyparasitized. The main associated parasites were Blastocystis spp. (89.8%), G. intestinalis (44.1%) and Endolimax nana (35.3%). In conclusion, a high prevalence of intestinal parasites was determined in the population studied, so these infections continue to be a public health problem in children from Ciudad Bolívar, Venezuela

RESUMO

Se presentan tres casos clínicos de niños atendidos en el Hospital Universitario San José de Popayán en Cauca, Colombia, quienes consultaron por una infección severa causada por Ascaris lumbricoides. La severidad de la infección tuvo como consecuencia en el primer caso una colangitis aguda, en el segundo caso una obstrucción intestinal con peritonitis generalizada, y en el tercer caso una perforación intestinal y choque séptico. El objetivo de mostrar estos casos es dar a conocer estas presentaciones clínicas poco frecuentes en el entorno médico. Además, se resalta la importancia del conocimiento sobre esta especie de parásito, que termina siendo un problema más de salud pública, no solo en nuestro país, sino en gran parte del mundo


We report three clinical cases of children treated at the San José University Hospital in Cauca, Colombia, who consulted with a severe infection caused by Ascaris lumbricoides. The severity of the infection resulted in acute cholangitis in the first case, in intestinal obstruction with generalized peritonitis in the second case, and in intestinal perforation and septic shock in the third case. The objective of this report is to inform the medical community about these unusual clinical presentations. In addition, the importance of this parasite is highlighted as a public health concern, not only in our country but also globally

RESUMO

Resumen La anemia se caracteriza por niveles bajos de hemoglobina. En Colombia, la anemia afecta al 27,7 % de la población. Las poblaciones más afectadas son los niños en edad preescolar, mujeres en edad reproductiva, embarazadas y personas de edad avanzada. Caso clínico: paciente de 58 años con cuadro clínico compatible con cor anémico, que requirió transfusión sanguínea. Mediante estudios de extensión se consideró una hemorragia digestiva por uncinariasis, por lo cual se dio un manejo antihelmíntico, con lo que tuvo buena evolución clínica y paraclínica. Discusión: hay múltiples factores de riesgo asociados con la adquisición de este parásito; se considera que esta entidad es una causa olvidada de hemorragia de vías digestivas y en algunos casos conlleva consecuencias graves como el cor anémico. El tratamiento se realiza mediante antihelmínticos, que tienen una efectividad entre el 62 % y el 92 %.


Abstract Anemia is characterized by low levels of hemoglobin. In Colombia, anemia affects 27.7% of the population. The most seriously affected populations are preschool children, women of reproductive age, pregnant women and the elderly. Clinical case: Upon admission, the 58-year-old patient was found to have a condition compatible with cardiomegaly and redistribution of blood flow and required a blood transfusion. Additional studies suggested that digestive hemorrhaging due to ancylostomiasis could be the cause. Treatment with anthelmintics was begun and had good clinical and paraclinical results. Discussion: Acquisition of this parasite, considered to be a forgotten cause of digestive bleeding, is associated with multiple risk factors. In some cases, there are severe consequences such as cardiomegaly and redistribution of blood flow. The effectiveness of treatment with anthelmintics ranges between 62% and 92%.

RESUMO

This study carried out a survey about enteropathogenic agents in domestic cats' shelter as a stage of investigation for the intermittent chronic diarrhea. Individual fecal samples from 39 cats with free access to the external environment were submitted to parasitological examination, parvovirus, and coronavirus by PCR, and Cryptosporidium spp., Giardia spp. and Tritrichomonas foetus by real-time PCR. From the cats evaluated, 30 (76.9%) were positive for one or more enteric agents, and coinfections were observed in 11 cats samples (28.2%). Helminth eggs were observed in 48.7% of cats (19/30), 16 (41%) were positive for parvovirus or coronavirus and 25.6% (10/30) were infected by protozoa. From the positives for protozoa, five cats were positive to T. foetus (12.82%). The first finding of this protozoan through PCR was in the southern Brazil, and the second was in the whole country. Chronic diarrhea in cats may be multifactorial in shelter animals where the population density is high and the control of parasitic, and viral infections are deficient. Moreover, it is due to poor hygiene conditions in these shelters. The factors associated with the proliferation of infectious diseases in shelters are correlated with new pathogens infections such as T. foetus.(AU)

RESUMO

Las parasitosis intestinales son consideradas un importante problema de salud pública. El propósito de la investigación fue relacionar el saneamiento ambiental con la prevalencia de parásitos intestinales en tres comunidades urbanas del municipio Maracaibo. Tipo de investigación descriptivo, correlacional, de diseño transversal. La identificación de los factores de riesgo del saneamiento ambiental se hizo mediante una ficha epidemiológica, participando un total de 345 individuos, incluyendo como variables para indagar el saneamiento: el almacenamiento de agua, acumulación de basura, presencia de fauna nociva y hacinamiento en la vivienda. Para la identificación de parásitos intestinales se efectuó un examen coproparasitológico directo con solución salina fisiológica y lugol. Se realizaron análisis estadísticos aplicando distribuciones de frecuencia, tablas de contingencias y asociación de variables mediante la prueba Chi cuadrado, aplicando el SPSS V.20. En cuanto a los principales factores de riesgo del saneamiento ambiental se encontró: almacenamiento de agua (98%), acumulación de basura (94%) y presencia de fauna nociva (92%). La prevalencia de parasitosis fue del46%, principalmente por Blastocystis sp (72%), resultando el 65% monoparasitado. El 48% presentó inadecuado saneamiento ambiental, 39% de la muestra presentó parasitosis cuando existe un deficiente saneamiento ambiental. En conclusión, se encontró que la prevalencia de las parasitosis fue alta, así como las de sus factores de riesgo asociadas, por lo que se demostró asociación entre el inadecuado saneamiento ambiental y la presencia de parasitosis.


Intestinal parasites are considered an important public health problem. The purpose of the research was to relate environmental sanitation to the prevalence of intestinal parasites in three urban communities of the Maracaibo municipality. Type of descriptive, correlational, cross-sectional research. The identification of risk factors for environmental sanitation was made through an epidemiological sheet, involving a total of 345 individuals, including as variables to investigate the sanitation: water storage, accumulation of garbage, presence of harmful fauna and overcrowding in housing. For the identification of intestinal parasites, a direct coproparasitological examination was performed with physiological saline solution and lugol. Statistical analyzes were performed applying frequency distributions, contingency tables and association of variables using the Chi square test, applying the SPSS V.20. Regarding the main risk factors of environmental sanitation, it was found: water storage (98%), garbage accumulation (94%) and presence of harmful fauna (92%). The prevalence of parasitosis was 46%, mainly by Blastocystis sp (72%), resulting in 65% monoparasitic. 48% presented inadequate environmental sanitation, 39% of the sample presented parasitosis when there is poor environmental sanitation. In conclusion, it was found that the prevalence of parasitic infections was high, as well as the associated risk factors, which led to an association between inadequate environmental sanitation and the presence of parasitosis in the studied communities.

RESUMO

BACKGROUND: Some reports are available on the prevalence of opportunistic parasitoses among hemodialysis (HD) patients, yet there is a paucity of data on the association of CD4+ T-cell counts with such infections. Therefore, this study aimed to determine the prevalence of intestinal parasites and Toxoplasma gondii in relation to CD4+ counts among HD patients in Alexandria, Egypt. METHODS: A comparative cross-sectional study was conducted on 120 HD patients and 100 apparently healthy individuals between December 2014 and January 2016. Data and samples (stool and blood) were collected from the participants after obtaining their informed consent. Stool samples were examined for parasites after concentration and staining, EDTA-blood samples were used for CD4+ counting by flow cytometry, and sera were analyzed for anti-Toxoplasma IgM and IgG antibodies. RESULTS: A significantly higher prevalence rate of intestinal parasitoses was found among HD patients compared to apparently healthy individuals (52.5% vs. 12.0%, respectively), with absence of helminths. Cryptosporidium species (32.5%), B. hominis(24.2%) and microsporidia (11.7%) were the most frequent parasites among HD patients, while B. hominis (13.0%), Cryptosporidium species (11.0%) and G. lamblia (4.0%) were the most frequent parasites among their counterparts. Statistically significant differences in parasite infection rates between patients and their counterparts were found for Cryptosporidium species, B. hominis and microsporidia. However, parasite species were not significantly associated with diarrhea. On the other hand, the overall T. gondii seroprevalence rate among HD patients was significantly higher than that among their counterparts (33.3% vs. 8%, respectively). HD patients with CD4+ counts < 200 cells/µl were twice more exposed to intestinal parasitoses compared to those with counts ≥200 cells/µl, but the difference was not statistically significant. However, low CD4+ counts were significantly associated with higher rates of Cryptosporidium species, microsporidia and T. gondii. CONCLUSIONS: Intestinal parasitoses and T. gondii infection rates are significantly higher among Egyptian HD patients compared to apparently healthy individuals, with Cryptosporidium species, B. hominis, microsporidia and T. gondii being the most frequent parasites. CD4+ counts < 200 cells/µl are significantly associated with Cryptosporidium species, microsporidia and T. gondii among HD patients. Therefore, regular screening of HD patients for opportunistic parasites is recommended.

RESUMO

Introduction: Intestinal parasitosis by helminths and protozoa is still today a global public health problem mainly affecting people living in conditions of social vulnerability, including rural communities. Objective: Describe human intestinal parasitosis and environmental contamination with helminths and protozoa in the Quilombola community of Quartel do Indaiá (of African descent) in the State of Minas Gerais, Brazil. Methods: A cross-sectional study was conducted of stool and soil samples by spontaneous sedimentation, and of plant samples by centrifugation sedimentation, to detect intestinal helminths and protozoa. Water samples were analyzed for total and fecal coliforms. Results: Helminths and protozoa were found in 45.5 percent of the people (n = 66). The species detected were Ascaris lumbricoides (18.2 percent), Entamoeba coli (18.2 percent), Endolimax nana (18.2 percent), ancylostoma (6.1 percent, Iodamoeba butschlii (4.6 percent), Giardia duodenalis (3 percent) and Trichuris trichiura (1.5 percent). More than one species were present in 19.7 percent of the samples. In 18 of the 39 sites sampled, the soil was contaminated with E. coli, E. nana, A. lumbricoides, I. butschlii and/or Enterobius vermicularis. Vegetables (n = 135) were contaminated in 75 samples with 7 of the 8 species analyzed. The contaminants were E. coli cysts, A. lumbricoides eggs and ancylostoma. All water samples were contaminated with total and fecal coliforms. Conclusions: The Quilombola community of Quartel do Indaiá had high levels of human infection and high environmental contamination with intestinal parasites or protozoa, probably due to lack of appropriate sanitary conditions. It is necessary to improve the access to treated water and sanitation(AU)


Introducción: El parasitismo intestinal por helmintos y protozoarios todavía es un problema de salud pública mundial, que afecta sobre todo personas en condiciones de vulnerabilidad social, incluso las comunidades rurales. Objectivo: Describir la infección humana y la contaminación ambiental por parásitos/comensales intestinales en una comunidade 'quilombola' Quartel do Indaiá (descendentes de esclavos) del Estado de Minas Gerais, Brasil. Métodos: Estudio de corte transversal con análisis de muestras fecales y de tierra por sedimentación espontánea, y de vegetales por sedimentación con centrifugación para detección de parásitos o comensales intestinales. Se analizaron muestras de agua para detección de coliformes totales y fecales. Resultados: Se observó la ocurrencia de parásitos o comensales en 45.5 por ciento de las personas (n = 66). Las especies detectadas fueron Ascaris lumbricoides (18,2 por ciento), Entamoeba coli (18,2 por ciento), Endolimax nana (18,2 por ciento), anquilostomas (6.1 por ciento), Iodamoeba butschlii (4,6 por ciento), Giardia duodenalis (3 por ciento), and Trichuris trichiura (1,5 por ciento). Para 19,7 por ciento de las muestras se detectaron más de una especie. El suelo estuvo contaminado en 18 de los 39 sitios muestreados, con presencia de E. coli, E. nana, A. lumbricoides, I. butschlii y/o Enterobius vermicularis. Los vegetales (n = 135) presentaron contaminación en 75 muestras de 7, entre 8 especies analizadas. Sus contaminantes fueron quistos de E. coli y huevos de A. lumbricoides y anquilostoma. Todas las muestras de agua estaban contaminadas por coliformes totales y fecales. Conclusiones: La comunidad 'quilombola' Quartel do Indaiá presentó alta infección humana y alta contaminación ambiental por parásitos o comensales intestinales, lo que se debe probablemente a la falta de condiciones sanitarias. Se necesita mejorar el acceso para agua tratada y estructuras de saneamiento(AU)

RESUMO

Las parasitosis siguen siendo un grave problema de salud en pediatría, no tanto por la mortalidad que ocasionan sino por la morbilidad y sus secuelas en el crecimiento y desarrollo de los niños y en su desempeño en la vida adulta. Dentro de los parásitos de mayor prevalencia en los niños, están los que se transmiten por contacto con el suelo (geohelmintos o helmintos transmitidos por contacto con el suelo, HTS), dentro de los cuales, los de mayor prevalencia, son los áscaris, tricocéfalos y uncinarias. Como los parásitos intestinales no se reproducen en el organismo humano, su principal fuente de contagio se da a través del suelo que esté contaminado con materias fecales. Es por esta razón que los principales factores determinantes son: contaminación fecal del ambiente, agua contaminada, falta de excretas y malos hábitos higiénicos, especialmente en el lavado de manos. Sus manifestaciones clínicas son variables en intensidad y en signos, hay que tener presente que muchas de las personas parasitadas pueden estar asintomáticas durante mucho tiempo, pero siguen excretando huevos en las fecales, contaminando así el ambiente y perpetuando su prevalencia. Por esta razón, la Organización Mundial de la Salud (OMS) recomienda que en aquellas regiones o áreas donde la prevalencia de las geohelmintiasis sea igual o superior al 20% se debe hacer una desparasitación masiva y con una periodicidad acorde con la gravedad de esta prevalencia. En la actualidad se dispone de antiparasitarios efectivos, fáciles de suministrar (incluso por personal no médico). Los más comunes (albendazol y mebendazol) actúan inhibiendo la síntesis de adenosín trifosfato (ATP) necesario para su supervivencia. Como solamente se absorbe entre el 1% y el 5% del medicamento y su metabolismo es rápido, los efectos secundarios son leves y transitorios. Lo ideal es emplearlos en los pacientes que vivan en zonas de riesgo y en comunidades con una prevalencia igual o mayor al 20%, continuando con desparasitaciones periódicas de acuerdo al comportamiento de la prevalencia. Es evidente el impacto que se logra con la desparasitación periódica, tanto en el crecimiento y en el estado nutricional, como en el desempeño cognitivo, así como sus efectos en el campo social y ambiental.


Parasitosis continues to be a serious problem in pediatrics, not only because it is a cause of death, but because of the morbility and the long-term effects it has on growth and development in children and later on in their adult life. The most prevalent parasites in children include those transmitted by contact with the soil (geohelminths or soil-transmitted helminths, STH), amongst which the most common are the ascaris, trichocephalia, and uncinaria. Since intestinal parasites are not produced inside the human body, they are mainly contracted through soil contaminated with fecal matter. Thus, the principal determining factors include fecal contamination in the environment, contaminated water, improper excreta management, and poor personal hygiene, especially hand washing. Its clinical manifestations vary in intensity and in signs; also, many individuals with parasites may be asymptomatic for a long period of time, but their fecal matter contains eggs, thus, contaminating the environment and perpetuating its prevalence. Therefore, the World Health Organization (WHO) recommends that regions where geohelminthiasis prevalence is 20% or higher should be massively treated for parasites with a periodicity that is appropriate for the seriousness of the prevalence. Currently, there are effective antiparsitics available that are easy to administer (even by non-medical personnel). The most common medications (albendazole and mebendazole) inhibit the synthesis of adenosine triphosphate (ATP) needed for survival. Since only between 1 and 5% of the medication is absorbed and children's metabolism is fast, secondary effects are minor and transitory. It is recommended that they be used in patients that live in high-risk areas and in communities with a prevalence of 20% or higher, conducting periodic mass drug administration for parasite removal depending on the behavior of the prevalence. Regular parasite removal has an evident impact on growth, nutritional state, cognitive performance, as well as its effects on the social and environmental fields.

RESUMO

OBJECTIVE: To describe the epidemiological and clinical profile of intestinal parasites in children in rural Central African Republic. PATIENTS AND METHODS: We conducted a multicenter cross-sectional study in Central African Republic rural areas. Children seen as outpatients regardless of the reason for consultation were included in the study after parental consent. Each stool sample sent to the laboratory in a plastic pot was subjected to a direct co-examination with physiological water. RESULTS: A total of 102 children were included in the study, of whom 53 were boys (51.96%), the median age was 4 years (3 months; 15 years old). They had a primary level of education in 31.37% of cases, 76.47% came from Health Region 1. Drilling was the source of drinking water in 61.76% of cases and the backwater was used for bathing by 26.47% of children. Abdominal pain was observed in 55 children (53.92%). The prevalence of intestinal parasitosis was 88.23%. Of 122 identified parasites, 96 were helminths (78.69%) and 26 were protozoa (21.31%). Of the three protozoan species isolated, Entamoeba histolytica was found in 15 cases (14.70%). The most common helminthiasis was Ascaris lumbricoides (40.19%). The frequency of parasitic infection was 92% in children aged from 5 to 9 years. Mono-parasitism was observed in 52.94% versus 33.33% for poly-parasitism. CONCLUSION: Intestinal parasitosis is a public health problem in Central African Republic rural areas. Improving access to drinking water for populations could reduce the magnitude of these diseases.

RESUMO

ABSTRACT: This study carried out a survey about enteropathogenic agents in domestic cats shelter as a stage of investigation for the intermittent chronic diarrhea. Individual fecal samples from 39 cats with free access to the external environment were submitted to parasitological examination, parvovirus, and coronavirus by PCR, and Cryptosporidium spp., Giardia spp. and Tritrichomonas foetus by real-time PCR. From the cats evaluated, 30 (76.9%) were positive for one or more enteric agents, and coinfections were observed in 11 cats samples (28.2%). Helminth eggs were observed in 48.7% of cats (19/30), 16 (41%) were positive for parvovirus or coronavirus and 25.6% (10/30) were infected by protozoa. From the positives for protozoa, five cats were positive to T. foetus (12.82%). The first finding of this protozoan through PCR was in the southern Brazil, and the second was in the whole country. Chronic diarrhea in cats may be multifactorial in shelter animals where the population density is high and the control of parasitic, and viral infections are deficient. Moreover, it is due to poor hygiene conditions in these shelters. The factors associated with the proliferation of infectious diseases in shelters are correlated with new pathogens infections such as T. foetus.


RESUMO: Uma pesquisa de agentes enteropatogênicos em gatos domésticos de um abrigo foi realizado como etapa da investigação das causas de diarreias crônicas intermitentes. Amostras fecais individuais de 39 gatos, com livre acesso ao ambiente externo, foram obtidas para pesquisa de helmintos através do exame parasitológico, investigação de parvovírus e coronavírus e de Cryptosporidium spp., Giardia spp. e Tritrichomonas foetus através de PCR em tempo real. Dos gatos avaliados, 30 (76,9%) foram positivos para algum ou mais de um destes agentes entéricos. Desses, 11 (28,2%) apresentaram co-infecções parasitárias. Ovos de helmintos foram observados em 48,7% dos gatos (19/30), 16 felinos (41%) foram positivos para parvovírus ou coronavírus e 25,6% (10/30) estavam infectados por protozoários. Dos positivos para protozoários, cinco apresentaram Tritrichomonas foetus (12,82%), um organismo pouco relatado no Brasil, sendo este o primeiro relato de detecção deste protozoário através de PCR em fezes de gatos no Sul do Brasil e o segundo no país. A diarreia crônica em gatos pode ser multifatorial em animais de abrigo onde a densidade populacional é elevada e os meios de controle parasitário e viral são deficitários, além das condições de higiene precárias. Os fatores associados à proliferação de doenças infecciosas em abrigos promovem o surgimento de infecções por novos patógenos como o Tritrichomonas foetus, até então pouco relatado no Brasil.
