[Comparative analysis of clinical characteristics, evolution and mortality of hospitalized patients with COVID-19 during the first and second wave of the pandemic (ECCOVID Study)]. / Análisis comparativo de las características clínicas, evolución y mortalidad de pacientes hospitalizados por COVID-19 durante la primera y segunda ola de la pandemia (Registro ECCOVID).

INTRODUCTION: Clinical features and outcomes of SARSCoV-2 infections may change between different waves of the pandemic. The objective of this study was to compare clinical characteristics and outcomes between two cohorts of patients hospitalized for COVID-19 during the first and second waves in Argentina. METHODS: Multicenter and prospective registry of patients =18 years old with a confirmed diagnosis of COVID-19 admitted to 18 hospitals in Argentina during the first wave (March to October 2020) and second wave (March to July 2021) of the pandemic. Demographics, clinical characteristics, and outcomes of these patients were compared. RESULTS: A total of 1691 patients were included (first wave n = 809, second wave n = 882). Hospitalized patients during the second wave were older (median 53 years vs. 61 years, p < 0.001), had more comorbidities (71% vs. 77%, p=0.007) and required more supplemental oxygen at admission (21% vs 62%, p < 0.001). During hospitalization, patients of the second wave required more supplemental oxygen (49% vs. 85%, p < 0.001), invasive ventilation (12% vs. 22%, p < 0.001) and had higher 30- day mortality (11% vs. 26%, p < 0.001). Comparing only patients who required supplemental oxygen during hospitalization, 30-day mortality was 20% and 30% p < 0.001 for the first and second wave, respectively. CONCLUSION: Compared to patients admitted during the first wave, patients admitted with SARS-CoV2 during the second wave in Argentina were more seriously ill and had a higher mortality.

Introducción: Las características clínicas y evolutivas de los pacientes con diagnóstico de COVID-19 pueden diferir entre las distintas olas de la pandemia. El objetivo de este estudio fue comparar las características clínicas, evolución y mortalidad de pacientes hospitalizados por COVID-19 durante la primera y segunda ola en Argentina. Métodos: Registro multicéntrico y prospectivo de pacientes = 18 años con diagnóstico confirmado de COVID-19 internados en 18 hospitales de Argentina durante la primera (marzo a octubre 2020) y la segunda ola (marzo a julio 2021) de la pandemia. Se compararon variables demográficas, características clínicas, y evolución a 30 días. Resultados: Se incluyeron un total de 1691 pacientes (primera ola n = 809, segunda ola n = 882). Los pacientes hospitalizados durante la segunda ola tenían mayor edad (mediana 53 años vs. 61 años, p < 0.001), comorbilidades (71% vs. 77%, p = 0.007) y requerimiento de oxígeno (21% vs. 62%, p < 0.001). Durante la hospitalización, los pacientes de la segunda ola requirieron más oxigenoterapia (49% vs. 85%, p < 0.001), asistencia mecánica respiratoria (12% vs. 22%, p < 0,001) y presentaron mayor mortalidad (11% vs. 26%, p < 0.001). Comparando únicamente a los que requirieron oxigenoterapia durante la hospitalización, la mortalidad a los 30 días fue de 20% y 30% p < 0.001 en la primera y segunda ola respectivamente. Conclusión: Comparados con los pacientes internados durante la primera ola, los internados durante la segunda ola de SARS-CoV-2 en Argentina presentaron mayor gravedad y mortalidad.

Amoebic liver abscess in a COVID-19 patient: a case report.

BACKGROUND: Amoebiasis is a parasitic disease caused by Entamoeba histolytica, which affects people living in low- and middle-income countries and has intestinal and extraintestinal manifestations. To date, knowledge on coronavirus disease 2019 (COVID-19) coinfection with enteric parasites is limited, and E. histolytica coinfection has not been previously described. Here we present the case of a patient with COVID-19 who, during hospitalisation, presented a clinical picture consistent with an amoebic liver abscess (ALA). CASE PRESENTATION: A 54-year-old man, admitted as a suspected case of COVID-19, presented to our hospital with dyspnoea, malaise, fever and hypoxaemia. A nasopharyngeal swab was positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by reverse-transcription polymerase chain reaction. After 7 days, he developed diarrhoea, choluria and dysentery. An abdominal ultrasound showed a lesion compatible with a liver abscess; stool examination revealed E. histolytica trophozoites, and additional serology for E. histolytica was positive. After 12 days of treatment with metronidazole, ceftazidime and nitazoxanide, the patient reported acute abdominal pain, and an ultrasound examination revealed free liquid in the abdominal cavity. An emergency exploratory laparotomy was performed, finding 3000 mL of a thick fluid described as "anchovy paste". Computed tomography scan revealed a second abscess. He ended up receiving 21 days of antibiotic treatment and was discharged with satisfactory improvement. CONCLUSION: Here we present, to the best of our knowledge, the first report of ALA and COVID-19 co-presenting. Based on their pathophysiological similarities, coinfection with SARS-CoV-2 and E. histolytica could change the patient's clinical course; however, larger studies are needed to fully understand the interaction between these pathogens.

Clinical characteristics and outcomes of hospitalized patients with SARS-CoV-2 infection in a Latin American country: Results from the ECCOVID multicenter prospective study.

BACKGROUND: Clinical features and outcomes of SARS-CoV-2 infections diverge in different countries. The aim of this study was to describe clinical characteristics and outcomes in a cohort of patients hospitalized with SARS-CoV-2 in Argentina. METHODS: Multicenter prospective cohort study of ≥18 years-old patients with confirmed SARS-CoV-2 infection consecutively admitted to 19 hospitals in Argentina. Multivariable logistic regression models were used to identify variables associated with 30-day mortality and admission to intensive care unit (ICU). RESULTS: A total of 809 patients were analyzed. Median age was 53 years, 56% were males and 71% had at least one comorbidity. The most common comorbidities were hypertension (32%), obesity (23%) and diabetes (17%). Disease severity at admission was classified as mild 25%, moderate 51%, severe 17%, and critical 7%. Almost half of patients (49%) required supplemental oxygen, 18% ICU, and 12% invasive ventilation. Overall, 30-day mortality was 11%. Factors independently associated with ICU admission were male gender (OR 1.81; 95%CI 1.16-2.81), hypertension (OR 3.21; 95%CI 2.08-4.95), obesity (OR 2.38; 95%CI 1.51-3.7), oxygen saturation ≤93% (OR 6.45; 95%CI 4.20-9.92) and lymphopenia (OR 3.21; 95%CI 2.08-4.95). Factors independently associated with 30-day mortality included age ≥60 years-old (OR 2.68; 95% CI 1.63-4.43), oxygen saturation ≤93% (OR 3.19; 95%CI 1.97-5.16) and lymphopenia (OR 2.65; 95%CI 1.64-4.27). CONCLUSIONS: This cohort validates crucial clinical data on patients hospitalized with SARS-CoV-2 in Argentina.

Factores de estrés percibidos entre los recién ingresados a la carrera de enfermería / Fatores de estresse percebidos entre carreiras de enfermagem recém entradas / Perceived stress factors among newcomers to the nursing career

Resumen: Objetivo: Conocer los factores de estrés más prevalentes en el alumnado novel de las Facultades de Enfermería de las Universidades de Cádiz, Córdoba, Huelva y Sevilla, así como su relación con sus características sociodemográficas, académicas, socioeconómicas, de orientación y de salud. Diseño: Estudio observacional, descriptivo, transversal. Metodología: Se encuestó a un total de 617 estudiantes (tasa de respuesta del 95,66 %) del primer curso del grado en Enfermería. Los participantes completaron dos cuestionarios: uno sociodemográfico y de salud; y un cuestionario de estrés percibido por alumnos noveles. Se realizó un análisis descriptivo de los factores de estrés con frecuencia, media y desviación típica. Las relaciones se examinaron con análisis diferencial a través de estudios no paramétricos U Mann-Whitney y Kruskal-Wallis. Resultados: Las situaciones que más estrés causan a los nuevos universitarios son: "hacer frente a los exámenes" y "la cantidad de trabajo que tengo que afrontar". En consecuencia, el factor más estresante es el "estrés académico" y el menos estresante el "sentimiento de soledad". Los estudiantes que perciben mayor estrés en varios factores son: mayores de 25 años, mujeres, el alumnado que procede de otras provincias y los que viven de alquiler durante el curso académico. Conclusiones: La entrada a la universidad produce factores de estrés en el alumnado de enfermería, que pueden afectar a su salud, su calidad de vida y su rendimiento académico. Hacer frentes a los exámenes y la alta carga académica son las principales determinantes de estrés. Sin embargo, sería conveniente indagar más en esta línea con el fin de conocer las posibles causas de este problema y poder desarrollar estrategias de prevención que mejoren la calidad de vida de estos estudiantes.

Resumo: Objetivo: Conhecer os fatores de estresse mais prevalentes em novos alunos das Faculdades de Enfermagem das Universidades de Cádis, Córdoba, Huelva e Sevilha, bem como sua relação com suas características sociodemográficas, acadêmicas, socioeconômicas, de orientação, educacionais e saúde. Delineamento: Estudo observacional, descritivo, transversal. Metodologia: Foram pesquisados ​​617 alunos (taxa de resposta de 95,66 %) do primeiro ano do curso de Enfermagem. Os participantes responderam a dois questionários: sociodemográfico e de saúde; e questionário de estresse percebido por alunos iniciantes. Foi realizada análise descritiva dos fatores de estresse com frequência, média e desvio padrão. Os relacionamentos foram examinados com análise diferencial por meio de estudos não paramétricos de U Mann-Whitney e Kruskal-Wallis. Resultados: As situações que mais estressam os novos estudantes universitários são "fazer exames" e "a quantidade de trabalho que tenho que enfrentar". Conseqüentemente, o fator mais estressante é o "estresse acadêmico" e o menos estressante são os "sentimentos de solidão". Os alunos que percebem o maior estresse em vários fatores são: maiores de 25 anos, mulheres, alunos que vêm de outras províncias e aqueles que vivem de aluguel durante o ano letivo. Conclusões: O ingresso na universidade produz fatores estressantes nos estudantes de enfermagem, que podem afetar sua saúde, sua qualidade de vida e seu desempenho acadêmico. A realização de exames e a alta carga acadêmica são apontados como os principais determinantes do estresse. No entanto, seria conveniente aprofundar as investigações nesse sentido para conhecer as possíveis causas desse problema e poder desenvolver estratégias de prevenção que melhorem a qualidade de vida desses alunos.

Abstract: Objective: To determine the prevalent stress factors among new students to the Faculties of Nursing at the Faculties of Nursing at the Universities of Cadiz, Cordoba, Huelva and Seville, and the influence of socio-demographic, academic, socio-economic, orientation and health factors. Design: A descriptive, observational and cross-sectional study. Methodology: 617 first year nursing students were surveyed (with a 95.66 % response rate) by means of two questionnaires, one for socio-demographics and health, the other for the stress perceived by new students. A descriptive analysis of the stress factors was then carried out for the frequency, mean and standard deviation. The relation between factors was examined through differential analysis by means of the Mann-Whitney U and Kruskal-Wallis non-parametric tests. Results: The situations of greatest anxiety among new undergraduates are "taking examinations" and "the amount of work I have to do". Consequently, the most stressful factor is "academic stress" whilst the least stressful is "feelings of loneliness". The students who feel most stress across various factors can be identified as: over 25, women, studying outside their home province, and living in rented accommodation during the academic year. Conclusions: Starting a degree in nursing is a stressful time, and students can find their health, quality of life and academic performance negatively affected. The main determinants of stress among new undergraduates are the joint demands of examinations and workload. It would undoubtedly be enlightening to examine this issue further in order to find the possible causes of the problem and to develop strategies that can help in its prevention and so improve the students' experience of university.

OBJECTIVE: To describe the genotypes of the carbapenemases reported from microbiological isolates of patients in Peru. METHODS: A systematic search of the biomedical literature about carbapenemases with genotypic confirmation was carried out. It included literature published from 1 January 2000 through 15 September 2019 in the PubMed, SCOPUS, Virtual Health Library, CONCYTEC Virtual Library, and Google Scholar databases, and other sources for the publication of abstracts or posters from national or international meetings. Two reviewers carried out the data selection and extraction. RESULTS: Fourteen studies, which carried out the genotypic characterization of 313 carbapenemases, were included. Of the total 313 reports, 103 analyzed enterobacteria: 74 were of Klebsiella pneumoniae, 11 of Proteus mirabilis, 7 of Enterobacter cloacae, and 11 of other enterobacteria; and 61 corresponded to bla NDM , 39 to bla KPC, and 3 to bla IMP . According to their molecular structure, 64 were metallo-ß-lactamases and 39 were serine-ß-lactamases. Of the total reports, 84 analyzed Pseudomonas aeruginosa: 79 corresponded to bla IMP , 4 to bla VIM , and 1 to bla GES. Of the total reports, 126 analyzed Acinetobacter baumannii: 55 corresponded to bla OXA-23 , 66 to bla OXA-24 , 3 to bla NDM, and 2 to bla OXA-143 . CONCLUSIONS: There is a limited number of publications about carbapenemases among patients in Peru. The genotype reports come primarily from hospitals in the country's capital. This is the first review that aims to identify the types of carbapenemases reported in enterobacteria, P. aeruginosa, and A. baummani.

Global management of patients with knee osteoarthritis begins with quality of life assessment: a systematic review.

BACKGROUND: Knee osteoarthritis (KOA) is a prevalent form of chronic joint disease associated with functional restrictions and pain. Activity limitations negatively impact social connectedness and psychological well-being, reducing the quality of life (QoL) of patients. The purpose of this review is to summarize the existing information on QoL in KOA patients and share the reported individual factors, which may influence it. METHODS: We conducted a systematic review examining the literature up to JAN/2017 available at MEDLINE, EMBASE, Cochrane, and PsycINFO using KOA and QOL related keywords. Inclusion criteria were QOL compared to at least one demographic factor (e.g., age, gender), lifestyle factor (e.g., functional independence), or comorbidity factor (e.g., diabetes, obesity) and a control group. Analytical methods were not considered as part of the original design. RESULTS: A total of 610 articles were reviewed, of which 62 met inclusion criteria. Instruments used to measure QoL included: SF-36, EQ-5D, KOOS, WHOQOL, HAS, AIMS, NHP and JKOM. All studies reported worse QoL in KOA patients when compared to a control group. When females were compared to males, females reported worse QOL. Obesity as well as lower level of physical activity were reported with lower QoL scores. Knee self-management programs delivered by healthcare professionals improved QoL in patients with KOA. Educational level and higher total mindfulness were reported to improve QoL whereas poverty, psychological distress, depression and lacking familial relationships reduce it. Surgical KOA interventions resulted in good to excellent outcomes generally; although, results varied by age, weight, and depression. CONCLUSION: KOA has a substantial impact on QoL. In KOA patients, QoL is also influenced by specific individual factors including gender, body weight, physical activity, mental health, and education. Importantly, education and management programs designed to support KOA patients report improved QoL. QoL data is a valuable tool providing health care professionals with a better comprehension of KOA disease to aid implementation of the most effective management plan.

[Identification of carbapenem-resistant genes in enterobacteria from peruvian hospitals, 2013-2017]. / Identificación de genes de resistencia a carbapenémicos en enterobacterias de hospitales de Perú, 2013-2017.

The global spread of carbapenemases is a significant public health concern. The aim of this report is to describe the presence of KPC-type carbapenem-resistant genes and enterobacteria isolated in 12 hospitals and forwarded to the Peruvian National Institute of Health's National Infection Reference Laboratory during the period between 2013 and 2017. The strains were identified by conventional methods; antimicrobial resistance was determined by phenotypic and biochemical methods. The presence of resistant genes was detected by conventional PCR. Eighty-three (83) strains harboring carbapenemases were identified: 26 (31.3%) carrying the blaKPC gene, 56 (67.5%) the blaNDM gene, and one strain (1.2%) with the blaIMP gene. This is the first report that shows the circulating carbapenemases genes in Hospitals in Peru of cases submitted for their confirmation to the National Reference Laboratory, so it is necessary to improve the surveillance to better understand their situation in our country.

La diseminación global de carbapenemasas es de importancia en la salud pública. El objetivo del estudio es describir la presencia de genes de resistencia a carbapenémicos tipo KPC y metalobetalactamasas en enterobacterias aisladas de 12 hospitales y remitidos al Laboratorio de Referencia Nacional de Infecciones Intrahospitalarias del Instituto Nacional de Salud de Perú durante los años 2013 al 2017.

ABSTRACT The global spread of carbapenemases is a significant public health concern. The aim of this report is to describe the presence of KPC-type carbapenem-resistant genes and enterobacteria isolated in 12 hospitals and forwarded to the Peruvian National Institute of Health's National Infection Reference Laboratory during the period between 2013 and 2017. The strains were identified by conventional methods; antimicrobial resistance was determined by phenotypic and biochemical methods. The presence of resistant genes was detected by conventional PCR. Eighty-three (83) strains harboring carbapenemases were identified: 26 (31.3%) carrying the blaKPC gene, 56 (67.5%) the blaNDM gene, and one strain (1.2%) with the blaIMP gene. This is the first report that shows the circulating carbapenemases genes in Hospitals in Peru of cases submitted for their confirmation to the National Reference Laboratory, so it is necessary to improve the surveillance to better understand their situation in our country.

The Prevalence, Correlates, Detection and Control of Diabetes among Older People in Low and Middle Income Countries. A 10/66 Dementia Research Group Population-Based Survey.

BACKGROUND: Little is known of the epidemiology of diabetes among older people in low and middle income countries. We aimed to study and compare prevalence, social patterning, correlates, detection, treatment and control of diabetes among older people in Latin America, India, China and Nigeria. METHODS: Cross-sectional surveys in 13 catchment area sites in nine countries. Diagnosed diabetes was assessed in all sites through self-reported diagnosis. Undiagnosed diabetes was assessed in seven Latin American sites through fasting blood samples (glucose > = 7 mmol/L). RESULTS: Total diabetes prevalence in catchment sites in Cuba (prevalence 24.2%, SMR 116), Puerto Rico (43.4%, 197), and urban (27.0%, 125), and rural Mexico (23.7%, 111) already exceeds that in the USA, while that in Venezuela (20.9%, 100) is similar. Diagnosed diabetes prevalence varied very widely, between low prevalences in sites in rural China (0.9%), rural India (6.6%) and Nigeria (6.0%). and 32.1% in Puerto Rico, explained mainly by access to health services. Treatment coverage varied substantially between sites. Diabetes control (40 to 61% of those diagnosed) was modest in the Latin American sites where this was studied. Diabetes was independently associated with less education, but more assets. Hypertension, central obesity and hypertriglyceridaemia, but not hypercholesterolaemia were consistently associated with total diabetes. CONCLUSIONS: Diabetes prevalence is already high in most sites. Identifying undiagnosed cases is essential to quantify population burden, particularly in least developed settings where diagnosis is uncommon. Metabolic risk factors and associated lifestyles may play an important part in aetiology, but this requires confirmation with longitudinal data. Given the high prevalence among older people, more population research is indicated to quantify the impact of diabetes, and to monitor the effect of prevention and health system strengthening on prevalence, treatment and control.

Hyperglycemia management in patients admitted to internal medicine in Spain: A point-prevalence survey examining adequacy of glycemic control and guideline adherence.

AIMS: Despite the increasing prevalence of hospitalized diabetic patients, there are few studies that evaluate the glycemic control and the rate of adherence to clinical practice guidelines for glucose monitoring and management in the hospital setting. METHODS: Crossover study using one-day surveys of all inpatients admitted to internal medicine wards from voluntary participating hospitals across Spain. Retrospective review of medical records was used to identify patients with hyperglycemia, causes for hospitalization, patients' demographic characteristics, appropriateness of glycemic monitoring and treatment during hospitalization. RESULTS: Among 5439 hospitalized patients studied there were 1000 (18.4%) with hyperglycemia in 111 participating hospitals. Patients mean age was 76.0±8.5 years (51.6% male). On admission, 91% had known diabetes (disease duration of 10.9±8.5 years), 5% had unknown diabetes and 4% had stress hyperglycemia. The comorbidity index (Charslon score) was 4 (interquartile range: 2 to 6) and 31% showed a high level of disability (Rankin scale). Main infringement in the process of care included lack of a recent HbA1c value (43.7%), use of sliding scale insulin therapy (20.7%), use of oral antidiabetic agents (8.9%), and less than three bedside point-of-care (POC) blood glucose test per day (17%). Glycemic target pre-meal and bedtime were achieved in 47% to 79.5% of POC. The rates of hypoglycemia (<70 mg/dL and <50mg/dL) were 10.3% and 2.4%, respectively. CONCLUSIONS: Our results suggest that there is an important gap between the clinical guidelines and both the management and the grade of glycemic control of diabetic inpatients.

The performance of laboratory tests in the management of a large outbreak of orally transmitted Chagas disease.

Orally transmitted Chagas disease (ChD), which is a well-known entity in the Brazilian Amazon Region, was first documented in Venezuela in December 2007, when 103 people attending an urban public school in Caracas became infected by ingesting juice that was contaminated with Trypanosoma cruzi. The infection occurred 45-50 days prior to the initiation of the sampling performed in the current study. Parasitological methods were used to diagnose the first nine symptomatic patients; T. cruzi was found in all of them. However, because this outbreak was managed as a sudden emergency during Christmas time, we needed to rapidly evaluate 1,000 people at risk, so we decided to use conventional serology to detect specific IgM and IgG antibodies via ELISA as well as indirect haemagglutination, which produced positive test results for 9.1%, 11.9% and 9.9% of the individuals tested, respectively. In other more restricted patient groups, polymerase chain reaction (PCR) provided more sensitive results (80.4%) than blood cultures (16.2%) and animal inoculations (11.6%). Although the classical diagnosis of acute ChD is mainly based on parasitological findings, highly sensitive and specific serological techniques can provide rapid results during large and severe outbreaks, as described herein. The use of these serological techniques allows prompt treatment of all individuals suspected of being infected, resulting in reduced rates of morbidity and mortality.

Ocurrencia de Isospora belli, Cryptosporidium spp y Cyclospora cayetanenesis en pacientes urbanos evaluados por síntomas gastrointestinales con o sin imnunosupresión / Occurrence of Isospora belli, Cryptosporidium and Cyclospora cayetanenesis spp in urban patients evaluated for gastrointestinal symptoms with or without immunosuppresion

Este estudio de corte transversal, estimó la ocurrencia de infecciones por coccidias intestinales (CI) en pacientes urbanos procedentes de Caracas-Venezuela. Se analizaron, 1 831 referencias de pacientes externos de ambos sexos y con edad promedio ± desviación estándar de 28,8 ± 22,93 años. En la Sección de Geohelmintiasis del Instituto de Medicina Tropical (SGH-IMT), se evaluaron 4 650 muestras de heces seriadas, por examen directo, formol tritón éter y Baermann, pertenecientes a 1 550 pacientes. Adicionalmente, la prueba de Ziehl-Neelsen modificada, se aplicó a las muestras fecales de 150 pacientes, por solicitud del médico tratante o sugerencia de SGH-IMT. La eosinofilia (40,54 por ciento; 225/555) constituyó el principal motivo de referencia y consulta. El promedio ± DS de contaje absoluto de eosinófilo (3 151 ± 5 161) demostró eosinofilias leves (63/204) y moderadas (25/204). Otros motivos de consulta fueron: dolor abdominal (27,72 por ciento; 122/440), náuseas/vómitos (19,03 por ciento; 83/436), pujo/tenesmo (16,05 por ciento; 70/436) y por último, la consistencia líquida de las heces (4,87 por ciento; 74/1 477). Los parasitados (43,7 por ciento; 677/1 550) presentaron evacuaciones pastosa (81,25 por ciento; 494/608) y blandas (37 por ciento; 57/608). Sólo, 5,92. por ciento (36/608) presentaron consistencia líquida. La prueba de Ziehl-Neelsen modificada demostró 12 casos positivos (8 por ciento) para CI: Isospora belli (5,33 por ciento; 8/150), Cryptosporidium spp (2 por ciento; 3/150) y Cyclospora cayetanensis (0,66 por ciento; 1/150). El único caso de ciclosporiosis estaba co-infectado con Blastocystis hominis y no presentó cambios en la consistencia de las heces. Estos resultados apoya la idea de que los médicos interconsultantes soliciten la aplicación de exámenes coproparasitológicos adicionales, en forma seriada, de bajo costo, para evaluar pacientes inmunocompetentes urbanos, con síntomas gastrointestinales/ eosinofilia, ...

These two years follow up; cross-sectional study estimates the occurrence of intestinal coccidias in urban patients from the metropolitan area of Caracas-Venezuela. One thousand eight hundred thirty one outpatient case reports were analyzed, both sex and 28.8 ± 22.93 years. Soil-transmitted helminthes laboratory of the Tropical Medicine Institute (SGH-IMT) evaluated 4 650 feces samples from 1 550 outpatients by direct, formol triton ether and Baermann techniques, Additionally, modified Ziehl-Neelsen, were done because of clinicians or SGH-IMT suggestion for 150 outpatients. Eosinophilia (40.54 percent; 225/555) was the major cause of referral and consultation. The mean of the absolute count of eosinophils (3 151+ 5 161) showed low (63/204) and moderate (25/204) eosinophila. Other causes of consultation were: abdominal pain (27.72 percent; 122/440), nausea/ vomiting (19.03 percent; 83/436), tenesmus/constipation (16.05 percent; 70/436) and finally, liquid fecal consistency (4.87 percent; 74/1477). Parasite infected patients (43.7 percent; 677/1550) had normal (81.25 percent; 494/608) and semi liquid feces (37 percent; 57/608). Only, 5.92 percent (36/608) had liquid consistency. Modified Ziehl-Neelsen demonstrates 12 positive IC (8 percent) for: Isospora belli (5.33. percent; 8/150), Cryptosporidium spp (2 percent; 3/150) and Cyclospora cayetanensis (0.66 percent; 1/150). The only case of cyclosporidiosis was co-infected with Blastocystis hominis and had normal feces. These results agrees with the idea for clinicians to ask for additional, low cost, serial parasitological test in feces, to evaluate urban inmunocompetent outpatients, with gastrointestinal symptoms/eosinophilia, even without diarrhea, because the basic feces techniques, used routinely, fails to make the precise parasite diagnostic, underestimating coccidiosis

Estudio de la fasciolosis hepática humana y parasitosis intestinales en el caserío Mesa Arriba del municipio Carache, estado Trujillo,Venezuela / Study of human hepatic fasciolosis and intestinal parasitosis in the Mesa Arriba Village, Carache Municipality, Trujillo State, Venezuela

Se realizó un estudio clínico epidemiológico para determinar la ocurrencia de fasciolosis hepática humana y parasitosis intestinales en el caserío Mesa Arriba, municipio Carache. estado Trujillo, Venezuela, zona descrita como endémica para fasciolosis bovina, donde dos casos aislados, se han reportado en humanos. Se estudiaron 98 personas previo consentimiento informado, a quienes se les realizó una encuesta epidemiológica, examen físico, hematología, aminotransferasas, estudio coproparasitológico y serológico: ELISA con antígeno de excreción-secreción de adultos de Fasciola hepatica (AFhES) y “Western blot”(WB). Con base en los datos obtenidos, se conoció que el 88,8% de los participantes había consumido berro silvestre (Rorippa nasturtium aquaticum) y 59,2% tuvo contacto con ganado vacuno. En el estudio coproparasitológico se encontró que el 47,9% presentó algún tipo de parásito intestinal, 20,4% correspondió a helmintos, 15,3% a protozoarios y 12,2% a infecciones mixtas. No se encontraron huevos de Fasciola hepatica. El 18,4% de las personas mostró eosinofilia. Se obtuvo un suero positivo por el método de ELISA, con bandas inespecíficas al WB-AFhES. Se administró tratamiento específico para parásitos intestinales. No se demostró fasciolosis humana en este trabajo, a pesar de encontrar factores favorables a la infección, pero el mismo representó una aproximación a su estudio epidemiológico en el estado Trujillo.

A clinical-epidemiological study to determine the occurrence of human hepatic fasciolosis and intestinal parasitosis was done at the Mesa Arriba Village, Carache Municipality, Trujillo State, Venezuela, area which has been described as endemic for bovine fasciolosis and where two isolated cases have been reported in humans. The study included 98 persons who, after previously signing an informed consent form, answered an epidemiological survey and were physically examined and submitted to the following laboratory tests: complete hematology, aminotransferase, and coproparasitology and serology; ELISA using Fasciola hepatica adult excretion-secretion antigen (AFhES) and “Western Blot” (WB). Based on the results obtained, it was found that 88.8% of participants had consumed wild watercress (Rorippa nasturtium aquaticum) and 59.2% had contact with bovine cattle. The coproparasitological study showed that 47.9% had some type of intestinal parasite: 20.4% corresponded to helmints, 15.3% to protozoa, and 12.2% mixed infections. There were no Fasciola hepatica eggs; 18.4% of the individuals showed eosinophilia. The ELISA test gave one positive serum with non-specific WB-AFhES bands. Specific anti-intestinal parasite treatment was indicated. Human fasciolosis was not demonstrated in this study, in spite of finding favorable factors for this infection, but is represents and approximation to its epidemiological study at Trujillo State.
