Detecção de antígenos e anticorpos de Cysticercus em fluido cerebrospinal de pacientes com meningite crônica

Chronic meningitism is a less frequent manifestation of neurocysticercosis caused by Taenia solium cysticerci. In the present study we used Co-agglutination (Co-A), a simple and rapid slide agglutination test to detect specific Cysticercus antigen in the 67 cerebrospinal fluid (CSF) samples from patients with chronic meningitis of unknown etiology. The results were compared with that of ELISA for detection of antibodies. Among these samples four (5.97%) were positive for Cysticercus antigen by Co-A test and six (8.95%) were positive for antibodies by ELISA. Two samples were positive by both Co-A and ELISA, two were positive only by Co-A and four were positive only by ELISA. In the present study, although Cysticercus antigen and antibodies were present in CSF samples from eight (11.94%) patients, we cannot affirm that all the cases of chronic meningitis are due to cysticercosis, but for any case of chronic meningitis of unknown origin, it would be useful to consider the possibility of cysticercal meningitis.Meningite crônica é manifestação pouco freqüente de neurocisticercose causada por cisticerco de Taenia solium. No presente estudo utilizamos co-aglutinação (Co-A) um teste simples e rápido de aglutinação para detectar antígeno específico de Cysticercus nas 67 amostras de fluido cerebrospinal (CSF) de pacientes com meningite crônica de etiologia desconhecida. Os resultados foram comparados com os de ELISA para detecção de anticorpos. Dentre estas amostras quatro (5,97%) foram positivas para antígenos de Cysticercus pelo teste Co-A e seis (8,95%) foram positivas para anticorpos por ELISA. Duas amostras foram positivas por ambos Co-A e ELISA, duas foram positivas somente por Co-A e quatro foram positivas somente por ELISA. No presente estudo embora antígenos e anticorpos de Cysticercus estivessem presentes nas amostras de CSF de oito pacientes (11,94%), não podemos afirmar que todos os casos de meningite crônica sejam devidos à cisticercose, mas para qualquer caso de meningite crônica de origem desconhecida seria útil considerar a possibilidade de meningite por cisticerco

Cysticercus antibodies and antigens in serum from blood donors from Pondicherry, India

The aim of the present study was to screen the serum of blood donors, which are apparently healthy and residing in Pondicherry or its neighboring districts of Tamil Nadu State, for specific detection of Cysticercus antigens and antibodies. A total of 216 blood samples were collected from blood donors at the Central Blood Bank, JIPMER Hospital, Pondicherry, India during January and February 2004. Enzyme-linked immunosorbent assay (ELISA) was used to demonstrate anti-Cysticercus antibodies and the Co-agglutination (CoA) was used to detect antigen in sera. 14 (6.48 %) males were positive for either anti-Cysticercus antibodies or antigens. Of these eight sera were positive for anti-Cysticercus antibodies and six were positive for antigens. Results of the present study show that serum Cysticercus antigen detection may be a useful adjunct to antibody testing for seroprevalence studies of cysticercosis in the community. The present study is the first kind of study, carried out to determine both cysticercal antibodies as well as antigens in the serum samples collected from the healthy blood donors.O objetivo do presente estudo foi examinar o soro de doadores de sangue que são aparentemente saudáveis e residentes em Pondicherry ou seus distritos vizinhos do estado de Tamil Nadu, para a detecção específica dos antígenos e anticorpos de Cysticercus. Um total de 216 amostras de sangue foram coletadas de doadores de sangue do "Central Blood Bank, JIPMER Hospital", Pondicherry, Índia, durante janeiro e fevereiro de 2004. ELISA foi usado para demonstrar anticorpos anti-Cysticercus e co-aglutinação (CoA) foi utilizada para detectar antígenos no soro. 14 (6.48%) homens foram positivos para antígenos e anticorpos anti-Cysticercus. Destes, oito soros foram positivos para anticorpos anti-Cysticercus e seis positivos para antígenos. Os resultados do presente estudo mostram que a detecção de antígenos de Cysticercus no soro pode ser um adjunto útil para o teste de anticorpos para estudos de soroprevalência de cisticercose na comunidade. O presente estudo é o primeiro do tipo, realizado para determinar tanto anticorpos de Cysticercus como antígenos nas amostras de soro coletadas de doadores de sangue aparentemente saudáveis

NEUROCYSTICERCOSIS IN CHILDREN PRESENTING WITH AFEBRILE SEIZURE: CLINICAL PROFILE, IMAGING AND SERODIAGNOSIS

Neurocysticercosis (NCC) is one of the major causes of childhood seizures in developing countries including India and Latin America. In this study neurological pediatric cases presenting with afebrile seizures were screened for anti-Cysticercus antibodies (IgG) in their sera in order to estimate the possible burden of cysticercal etiology. The study included a total of 61 pediatric afebrile seizure subjects (aged one to 15 years old); there was a male predominance. All the sera were tested using a pre-evaluated commercially procured IgG-ELISA kit (UB-Magiwell Cysticercosis Kit ™). Anti-Cysticercus antibody in serum was positive in 23 of 61 (37.7%) cases. The majority of cases with a positive ELISA test presented with generalized seizure (52.17%), followed by complex partial seizure (26.08%), and simple partial seizure (21.73%). Headaches were the major complaint (73.91%). Other presentations were vomiting (47.82%), pallor (34.78%), altered sensorium (26.08%), and muscle weakness (13.04%). There was one hemiparesis case diagnosed to be NCC. In this study one child without any significant findings on imaging was also found to be positive by serology. There was a statistically significant association found between the cases with multiple lesions on the brain and the ELISA-positivity (p = 0.017). Overall positivity of the ELISA showed a potential cysticercal etiology. Hence, neurocysticercosis should be suspected in every child presenting with afebrile seizure especially with a radio-imaging supportive diagnosis in tropical developing countries or areas endemic for taeniasis/cysticercosis.Neurocisticercose é uma das causas mais comuns de crises em crianças em países em desenvolvimento incluindo Índia e América Latina. Neste estudo casos neurológicos pediátricos, apresentando crises afebris foram selecionados através de anticorpos anti-Cysticercus (IgG) no seu soro para avaliar possível etiologia de Cysticercus. O estudo incluiu total de 61 casos pediátricos de indivíduos com crises afebris (idade de um a 15 anos); houve predominância de pacientes do sexo masculino. Todos os soros foram testados usando um kit comercial IgG-ELISA (UB-Magiwell Cysticercosis kit™) avaliado previamente. O anticorpo anti-Cysticercus no soro foi positivo em 23 de 61 casos (37,7%). A maioria dos casos com teste de ELISA positivo apresentava crises generalizadas (52,17%), seguida por casos de crises parciais complexas (26,08%) e crises parciais simples (21,73%). Dores de cabeça foram a queixa principal (73,91%). Outras manifestações foram vômitos (47,82%), palidez (34,78%), sensório alterado (26,08%) e fraqueza muscular (13,04%). Houve um caso de hemiparesia diagnosticado como NCC. Neste estudo uma criança sem quaisquer achados significantes às imagens apresentou sorologia positiva. Houve associação estatística significante entre os casos com múltiplas lesões no cérebro e a positividade pelo ELISA (p = 0,017). No seu conjunto a positividade pelo ELISA demonstra etiologia potencial para a cisticercose. Portanto neurocisticercose deve ser suspeitada em qualquer criança apresentado crises afebris com imagem que sugira diagnóstico em países tropicais em desenvolvimento ou em áreas endêmicas para teníase/cisticercose

Geographical Variation in Antibiotic-Resistant Escherichia coli Isolates from Stool, Cow-Dung and Drinking Water

Little information is available on relationships between the biophysical environment and antibiotic resistance. This study was conducted to investigate the antibiotic resistance pattern of Escherichia coli isolated from child stool samples, cow-dung and drinking water from the non-coastal (230 households) and coastal (187 households) regions of Odisha, India. Susceptibility testing of E. coli isolates (n = 696) to the following antibiotics: tetracycline, ampicillin/sulbactam, cefuroxime, cefotaxime, cefixime, cotrimoxazole, amikacin, ciprofloxacin, norfloxacin and nalidixic acid was performed by the disk diffusion method. Ciprofloxacin minimum inhibitory concentration (MIC) values were determined for ciprofloxacin-resistant isolates (n = 83). Resistance to at least one antibiotic was detected in 90% or more of the E. coli isolates. Ciprofloxacin MIC values ranged from 8 to 32 µg/mL. The odds ratio (OR) of resistance in E. coli isolates from children’s stool (OR = 3.1, 95% CI 1.18–8.01), cow-dung (OR = 3.6, 95% CI 1.59–8.03, P = 0.002) and drinking water (OR = 3.8, 95% CI 1.00–14.44, P = 0.049) were higher in non-coastal compared to coastal region. Similarly, the co-resistance in cow-dung (OR = 2.5, 95% CI 1.39–4.37, P = 0.002) and drinking water (OR = 3.2, 95% CI 1.36–7.41, P = 0.008) as well as the multi-resistance in cow-dung (OR = 2.2, 95% CI 1.12–4.34, P = 0.022) and drinking water (OR = 2.7, 95% CI 1.06–7.07, P = 0.036) were also higher in the non-coastal compared to the coastal region

is enhanced surveillance required?

OBJECTIVES: To report on relevant national surveillance systems of (N)CC and taeniasis (the infection with the adult tapeworm) in the European Union/European Economic Area, and to assess the magnitude of (N)CC occurrence by retrieving information on cases for the period 2000-2016. METHODS: (N)CC cases were retrieved via national reporting systems, a systematic literature search, contact with clinicians, and a search for relevant "International Statistical Classification of Diseases and Related Health Problems" (ICD)-based data. RESULTS: Mandatory notification systems for (N)CC were found in Hungary, Iceland and Poland. Ten cases were reported in Poland and none in Hungary and Iceland. Through the systematic literature review and information given by clinicians, 263 individual and 721 aggregated (N)CC cases from 19 European countries were identified. ICD-based data were obtained from five countries. From 2000 to 2016, a total of 3,489 cases (N)CC cases were coded: 832 in Italy, 8 in Latvia, 357 in Portugal, 2116 in Spain and 176 in Sweden. CONCLUSION: Despite being classified as a possible eradicable disease, (N)CC is still diagnosed across Europe, yet its true extent and impact remain unclear.publishersversionpublishe

A review of concurrent infections of malaria and dengue in Asia

Concurrent infections of malaria and dengue are when both of these mosquito-borne diseases occur simultaneously in an individual. In this review, reported cases with these co-infections in Asia are discussed. The focus is on the overlapping clinical presentations and the difficulties encountered in differential diagnosis. Also, cases reported in some special conditions, viz., pregnancy, foetal infections, and co-infections with one or more other infectious agents are highlighted. Due to similar clinical presentations of malaria and dengue, these co-infections may give rise to an incorrect diagnosis. Moreover, the treatment regimens for these co-infections are not the same as those for mono-infections. Hence, a delay in implementing the appropriate treatment regimen for these concurrent infections due to poor diagnosis can be fatal. The present review is intended to increase awareness about the clinical significance and the importance of these co-infections among clinicians, public health workers and health authorities in the Asian region. Though malaria-dengue concurrent infections are seldom reported from the Asian region, it is probably increasing particularly in the countries known to be endemic for both of the above diseases. A compulsory reporting of the incidences of malaria-dengue concurrent infections is recommended
