ABSTRACT

Abstract INTRODUCTION: Hepatitis B virus (HBV) infection is a public health problem; therefore, we aimed to report HBV genotypes in Ceará, Brazil. METHODS: A total of 103 HBsAg-positive samples were subjected to HBV genotyping and subgenotyping. RESULTS: The following genetic compositions of samples were found: F-54% (F2-83.33%), A-40% (A1-65%), D-6%, C2-1%, E-1%, and G-1%. CONCLUSIONS: Some genotypes are only prevalent in certain parts of the world; however, the State of Ceará is a hub for migration and has one of the most important liver transplantation centers in Brazil, which can explain the prevalence of the F genotype.

ABSTRACT

Abstract INTRODUCTION: The transmission of Chagas disease (CD) through blood transfusion, organ transplantation, and oral transmission has gained greater visibility as a result of intensified vector control activities in endemic regions and to control CD in non-endemic regions. In Brazil, Ceará is one of the states that perform the most organ transplants. Therefore, the objective of this study was to assess the prevalence of Trypanosoma cruzi infection in organ donor candidates. METHODS: A retrospective analysis was performed on data from potential organ donors at the Center of Transplantation of the State of Ceará from 2010 - 2015. RESULTS: Data from a total of 2,822 potential donors were obtained, of which 1,038 were effective donors and 1,784 were excluded, likely due to lack of family authorization or medical contraindication. The prevalence of T. cruzi infection among these potential donors was 1.3% (n = 29). The majority of infected donors were males aged 41 - 60 years, residing in the interior of the state. Interestingly, 72.4% (n = 21) had positive or inconclusive serology for additional infections, such as cytomegalovirus, hepatitis B and C, and toxoplasmosis. Probability analysis revealed that stroke was the most common cause of death among potential donors with CD. CONCLUSIONS: There was a high prevalence of CD and other coinfections among potential solid organ donors in Ceará, and statistical tests have shown that these individuals are at increased risk of stroke when compared to potential non-reactive donors. This work highlights the importance of screening DC infection in potential donors.

ABSTRACT

Introduction: Signaling lymphocyte activation molecule (SLAM) is a self-ligand receptor on the surface of activated T- and B-lymphocytes, macrophages, and DC. Studies have shown PBMC from healthy individuals exposed to Leishmania differ in IFN-γ production. Objective: We investigated the role of SLAM signaling pathway in PMBC from high (HP) and low (LP) IFN-γ producers exposed to L. braziliensis in vitro. Methods: PBMC from 43 healthy individuals were cultured with or without antigen, α-SLAM, rIL-12 and rIFN-γ. The cytokines production was evaluated by ELISA, and SLAM expression by flow cytometry. Results: L. braziliensis associated with rIFN-γ or rIL-12 reduced early SLAM but did not modify this response later in HP. α-SLAM did not alter CD3+SLAM+ expression, and not affected IFN-γ and IL-13 production, in both groups, but increased significantly IL-10 in HP. Leishmania associated with α-SLAM and rIL-12 increased IFN-γ in LP, as well as IL-13 in HP. LP group presented low IFN-γ and IL-13 production, and low SLAM expression. Conclusion: Collectively, these findings suggest that when PBMC from healthy individuals are sensitized with L. braziliensis in vitro, SLAM acts in modulating Th1 response in HP individuals and induces a condition of immunosuppression in LP individuals.

Introdução: A molécula de sinalização para ativação linfocítica (SLAM) é um receptor autoligante na superfície de linfócitos T e B ativados, macrófagos e DC. Estudos têm mostrado que PBMC de indivíduos saudáveis expostos à Leishmania diferem na produção de IFN-γ. Objetivo: Nós investigamos o papel da via de sinalização de SLAM em PMBC de altos produtores de IFN-γ (AP) e baixos (BP) expostos à L. braziliensis in vitro. Métodos: PBMC de 43 indivíduos saudáveis foram cultivadas com ou sem antígeno, α-SLAM, rIL-12 e rIFN-γ. Foi avaliada a produção de citocinas por ELISA e expressão de SLAM por citometria de fluxo. Resultados: L. braziliensis associado a rIFN-γ ou rIL-12 reduziu a expressão inicial de SLAM, mas não modificou esta resposta mais tarde em AP. α-SLAM não alterou a expressão de CD3+SLAM+, e não afetou a produção de IFN-γ e IL-13, em ambos os grupos, mas aumentou significativamente IL-10 em AP. Leishmania associada a α-SLAM e rIL-12 aumentou IFN-γ em BP, assim como IL-13 em AP. BP apresentaram baixa produção de IFN-γ e IL-13 e baixa expressão de SLAM. Conclusão: Coletivamente, esses achados sugerem que quando PBMC de indivíduos saudáveis são sensibilizados por L. braziliensis in vitro, SLAM atua na modulação da resposta Th1 em indivíduos AP e induz uma condição de imunossupressão em indivíduos BP.

ABSTRACT

Úlceras genitais são manifestações clínicas de etiologias diversas, o que pode dificultar o diagnóstico. Este relato de caso trata­se de mulher de 64 anos, com histórico de úlcera genital dolorosa há 4 meses, progressiva apesar do uso prévio de antiviral. Apresentava lesão ulcerada com comprometimento perianal. Histopatológico revelou neovascularização, edema e infiltrado inflamatório. Realizou tratamento com aciclovir endovenoso por 14 dias, com melhora parcial. O herpes simples crônico manifesta­se como verruga ou úlcera de pelo menos um mês, geralmente em imunossuprimidas. A resistência a agentes antivirais é uma complicação encontrada, mas a resposta ao tratamento costuma ser mais lenta do que nas infecções comuns.


Genital ulcers are clinical manifestations of diverse etiologies, which can make diagnosis difficult. This case report is about a 64­year­old woman with a history of progressive genital ulcer pain for 4 months, despite prior antiviral use. The ulcerated lesion showed perianal involvement. Histopathology revealed neovascularization, edema and inflammatory infiltrate. Despite the use of intravenous acyclovir for 14 days, the improvement was partial. Chronic herpes simplex reveals wart or ulcer of at least one month, usually in immunosuppressed patients. A resistance to antiviral agents is a complication factor, but the treatment response to common infections is usually slower.

ABSTRACT

In 2009, the World Health Organization (WHO) issued a new guideline that stratifies dengue-affected patients into severe (SD) and non-severe dengue (NSD) (with or without warning signs). To evaluate the new recommendations, we completed a retrospective cross-sectional study of the dengue haemorrhagic fever (DHF) cases reported during an outbreak in 2011 in northeastern Brazil. We investigated 84 suspected DHF patients, including 45 (53.6%) males and 39 (46.4%) females. The ages of the patients ranged from five-83 years and the median age was 29. According to the DHF/dengue shock syndrome classification, 53 (63.1%) patients were classified as having dengue fever and 31 (36.9%) as having DHF. According to the 2009 WHO classification, 32 (38.1%) patients were grouped as having NSD [4 (4.8%) without warning signs and 28 (33.3%) with warning signs] and 52 (61.9%) as having SD. A better performance of the revised classification in the detection of severe clinical manifestations allows for an improved detection of patients with SD and may reduce deaths. The revised classification will not only facilitate effective screening and patient management, but will also enable the collection of standardised surveillance data for future epidemiological and clinical studies.

ABSTRACT

INTRODUCTION: The dengue hemorrhagic dengue (DHF) remains an important public health problem in Brazil. The objective of this study was to analyze the epidemiological characteristics of DHF cases during the 2003 epidemic in Ceará. METHODS: Suspected DHF cases with onset of symptoms between January and December 2003 were investigated. RESULTS: 37,964 classic dengue cases and 291 DHF cases were reported. Among the cases discarded, 75.5 percent were serologically positive but did not meet the criteria recommended by the World Health Organization (WHO). The DHF patients' median age was 30 years (2 - 88). Among the hemorrhagic manifestations, petechiae were the most (32.6 percent) frequent. Cases of gastrointestinal bleeding, ascites, pericardial pleural effusion, hepatomegaly, hypotension and shock showed higher risk of progression to death (p <0.05). CONCLUSIONS: The introduction of a new serotype (DENV-3) in Ceará, which encountered a susceptible population and high vector density, may have been the primary agent responsible for the magnitude of the epidemic. Timely and appropriate medical care, along with an organized care structure are essential for reducing its lethality.


INTRODUÇÃO: A febre hemorrágica do dengue (FHD) permanece como um importante problema de saúde pública no Brasil. O objetivo deste estudo é analisar os aspectos epidemiológicos dos casos de dengue hemorrágico durante a epidemia de 2003, no Ceará. MÉTODOS: Foram investigados os casos suspeitos de FHD, com início de sintomas no período de janeiro a dezembro de 2003. RESULTADOS: Foram reportados 37.964 casos de dengue clássica, com 291 casos de FHD. Entre os casos descartados, 75,5 por cento apresentaram sorologia positiva, mas não preenchem os critérios recomendados pela Organização Mundial de Saúde. A mediana de idade dos pacientes com FHD foi de 30 anos (2 - 88). Para manifestações hemorrágicas, as petéquias com 32,6 por cento foram as mais frequentes. Os casos de hemorragia digestiva, ascite, derrame pleural e pericárdico, hepatomegalia, hipotensão e choque apresentaram maior risco de progressão para óbito (p <0,05). CONCLUSÕES: A introdução de um novo sorotipo (DENV-3) no Ceará, encontrando a população suscetível e a alta densidade do vetor podem ter sido os principais responsáveis pela magnitude da epidemia. A atenção médica oportuna e adequada, bem como uma estrutura organizada de cuidado aos pacientes são indispensáveis para reduzir a letalidade.

ABSTRACT

INTRODUÇÃO: A doença de Chagas, causada pelo Trypanosoma cruzi, é tratada com benzonidazol, tendo o inconveniente de apresentar efetividade parcial e alta toxicidade, que varia desde reações de hipersensibilidade a aplasia medular. O objetivo foi descrever e avaliar a ocorrência de reações adversas em pacientes chagásicos em tratamento com benzonidazol em Fortaleza, Ceará. MÉTODOS: Estudo descritivo prospectivo envolvendo 32 pacientes chagásicos crônicos tratados com benzonidazol entre janeiro de 2005 e abril de 2006. Dados sociodemográficos e clínicos foram coletados de questionários, entrevistas e exames laboratoriais. As amostras de sangue foram coletadas antes, com 30 e 60 dias de tratamento. RESULTADOS: Reações adversas foram relatadas em 28 (87,5 por cento) pacientes tratados, tendo sido as mais frequentes: prurido (50 por cento), formigamento (43,8 por cento), fraqueza muscular (37,5 por cento) e rash cutânea (31,3 por cento). Dos 28 pacientes com reações adversas, oito (28,57 por cento) interromperam o tratamento. Reações adversas que culminaram com a suspensão do tratamento foram formigamento sete (87,5 por cento) ou erupção cutânea cinco (62,5 por cento). Observou-se aumento discreto dos níveis de aminotransferases durante o tratamento em (9,4 por cento) pacientes. CONCLUSÕES: Concluindo, o acompanhamento farmacoterapêutico dos pacientes chagásicos é de grande relevância na prevenção e detecção precoce das reações adversas a medicamentos.


INTRODUCTION: Chagas disease is caused by Trypanosoma cruzi and treated with benznidazole (BNZ). This drug has the troublesome features of presenting partial effectiveness and high toxicity ranging from hypersensitivity reactions to medullary aplasia. The objective here was to describe and evaluate the occurrence of adverse reactions in Chagas disease patients treated with benznidazole in Fortaleza, Ceará. METHODS: This was a prospective descriptive study involving 32 chronic Chagas patients treated with benznidazole between January 2005 and April 2006. Sociodemographic and clinical data were collected through questionnaires, interviews and laboratory tests. Blood samples were collected before treatment and after 30 and 60 days of treatment. RESULTS: Adverse reactions were reported in 28 patients (87.5 percent) patients and the most frequent of these were pruritus (50 percent), prickling (43.8 percent), muscle weakness (37.5 percent) and skin rash (31.3 percent). Out of the 28 patients with adverse reactions, eight (28.57 percent) discontinued their treatment. The adverse reactions that culminated with discontinuation of the treatment were prickling (7; 87.5 percent) or skin eruptions (5; 62.5 percent). There was a slight increase in aminotransferase levels during the treatment in 9.4 percent of the patients. CONCLUSIONS: Following up the drug therapy administered to Chagas patients is of great importance for prevention and early detection of adverse reactions to drugs.

ABSTRACT

Nosso grupo de pesquisa tem desenvolvido experiências de monitoramento de reações adversas em pacientes chagásicos em tratamento com benznidazol. A proposta de produção deste artigo nasceu da constatação da escassez de artigos que reunissem vários aspectos relacionados ao tratamento etiológico da doença de Chagas. Portanto, foram realizadas buscas de artigos originais e revisões indexadas, nas bases do Medline e Lilacs, de publicações relativas ao tratamento etiológico da doença de Chagas desde os primeiros ensaios terapêuticos até o momento incluindo mecanismo de ação, reações adversas, critérios de cura e indicações de tratamento do consenso brasileiro. Os medicamentos nifurtimox e benznidazol, utilizados atualmente no tratamento da doença de Chagas, apresentam eficácia acima de 80por cento na fase aguda e de 8por cento a 30por cento na fase crônica. O sucesso da terapêutica esbarra em alguns pontos tais como: esquema terapêutico prolongado, reações adversas, variabilidade genética dos parasitos e cepas naturalmente resistentes aos fármacos. Os resultados desta atualização revelam a necessidade do desenvolvimento de novos fármacos com atividade anti-T. cruzi que, por um lado, apresentem menor toxicidade, e por outro, maior eficácia na fase crônica.

ABSTRACT

Enteroparasites are related to gastrointestinal alterations among patients with HIV/AIDS, some causing severe manifestations in the period before the institution of the highly active antiretroviral therapy (HAART). The prevalence of enteroparasitoses in patients with HIV/AIDS seen at two hospitals in Ceará , Brazil, was compared in the pre-HAART (Group 1; n = 482) and HAART (Group 2; n = 100) eras. Fecal parasitologic examinations (FPE) were performed using the direct, Lutz, Baermann-Moraes and modified Ziehl-Neelsen methods. The following parasites were detected in Groups 1 and 2, respectively: Strongyloides stercoralis - 30.1 percent and 11 percent (p<0.0001), Ascaris lumbricoides - 15.6 percent and 2 percent (p<0.0001), hookworms - 13.7 percent and 2 percent (p<0.0001), Trichuris trichiura - 13.1 percent and 1 percent (p<0.0001), Hymenolepis nana - 0 and 1 percent (p = 0.1718), Giardia duodenalis - 7.9 percent and 1 percent (p = 0.0076), Entamoeba histolytica/dispar - 3.3 percent and 1 percent (p = 0.3301), Isospora belli - 4.8 percent and 1 percent (p = 0.0993), Cryptosporidium sp. - 8.1 percent and 0 (p = 0.0007), and non-pathogenic protozoans as well. There was a significant reduction in the prevalence of enteroparasites between the eras (63.9 percent to 24 percent; p<0.0001). In the HAART era, the following observations were made: greater frequency of enteroparasites in patients without antiretroviral therapy (p = 0.0575), as in those with AIDS (p = 0.08), and diarrhea (36 percent of the patients); lack of association with positive FPE (p = 0.626); and non-detection of Cryptosporidium sp. Strongyloides stercoralis showed an elevated prevalence in the two eras and was more frequent in men (32.41 percent) than women (19.04 percent) of Group 1 (p = 0.018), a finding suggesting the transmission of the helminth through sodomy. The advent of the HAART modified the profile of opportunistic infections, including parasites, probably due...

ABSTRACT

Dengue é doença viral sistêmica que ocorre de forma epidêmica em áreas tropicais e subtropicais da Asia, Américas e Africa. O vírus da dengue pertence ao gênero Flavivirus e à família Flaviviridae (arbovírus do grupo B). Aedes aegypti é o principal vetor e verdadeiro reservatório. A febre na dengue clássica persiste por período de dois a cinco dias com cefaléia intensa, mialgia, artralgia e dor retro-orbital. Alterações cutâneas incluem diversos achados como erupção morbiliforme que pode ser pruriginosa e que gera descamação residual, algumas manifestações hemorrágicas discretas como epistaxe, petéquias e sangramento gengival. Extravasamento capilar de plasma é responsável pela hemoconcentração e trombocitopenia observadas e que caracterizam a dengue hemorrágica. Manifestações cutâneas da dengue hemorrágica incluem lesões hemorrágicas disseminadas como petéquias e equimoses, mas também instabilidade hemodinâmica com pulso filiforme, pressão arterial convergente, extremidades frias, confusão mental e choque.


Dengue fever is a systemic viral disease that occurs epidemically in tropical and subtropical regions of Asia, Americas and Africa. The dengue virus belongs to the genus Flavivirus of the family Flaviviridae (group B arbovirus). Aedes aegypti is the major vector and the true reservoir for the virus. Classic dengue fever lasts for two-five days, with severe headache, intense myalgia, arthralgia and retro-orbital pain. Cutaneous alterations include several findings such as a diffuse morbilliform rash that may be pruritic and heals with desquamation, and minor bleeding phenomena such as epistaxis, petechiae, and gingival bleeding. Diffuse capillary leakage of plasma is responsible for the hemoconcentration and thrombocytopenia that characterize dengue hemorrhagic fever. Cutaneous manifestations of dengue hemorrhagic fever include many disseminated hemorrhagic lesions such as petechiae and ecchymoses, but also hemodynamic instability with filiform pulse, narrowing of pulse pressure, cold extremities, mental confusion, and shock.

ABSTRACT

Dengue outbreaks have occurred in several regions in Brazil and cocirculating dengue virus type 1 (DENV-1), DENV-2, and DENV-3 have been frequently observed. Dual infection by DENV-2 and DENV-3 was identified by type-specific indirect immunofluorescence assay and confirmed by reverse transcription polymerase chain reaction in a patient in Ceará with a mild disease. This is the first documented case of simultaneous infection with DENV-2 and DENV-3 in Brazil. Sequencing confirmed DENV-2 and DENV-3 (South-East/American) genotype III and (SriLanka/India), genotype III respectively.

ABSTRACT

As reações falso-positivas em testes de ELISA(Enzima Linked Immuno Sorbent Assay) podem acontecer. O presente trabalho demonstra a existência de reações cruzadas no teste de ELISA anti-HIV em 33 pacientes de 0 - 15 anos com diagnóstico de calazar. Foram observados 5 casos positivos para o teste de ELISA anti-HIV na primeira reação e em 4 (12,12%)houve a permanência da positividade na segunda reação sorológica. Estes pacientes positivos apresentaram Western Blot anti-HIV negativos. Devido o estigma da infecção pelo HIV, fica imperativo, em zonas endêmicas de Leishmaniose Visceral Americana, nos pacientes que tenham apresentado ELISA anti-HIV positivo, a realização de outro teste comprobatório do HIV( Western Blot)
