Adverse reactions following mass drug administration with diethylcarbamazine in lymphatic filariasis endemic areas in the Northeast of Brazil

INTRODUCTION: The Global Programme to Eliminate Lymphatic Filariasis was launched with the goal of eliminating this disease via the annual mass drug administration (MDA) of a single dose of antifilarial drugs. Adverse drug reactions following MDA are a major factor of poor treatment adherence in several countries. This study assessed the occurrence of adverse drug reactions (ADRs) following the first round of mass treatment in two communities treated with different dosages of diethylcarbamazine (DEC) in the City of Recife, Brazil. METHODS: Population-based cross-sectional surveys were conducted in a random sample of the population living in both communities (Areas I and II). The dose of DEC recommended by the WHO (6mg/kg) was calculated based on the individual's weight-for-age. In Area II, weight differences between the genders were also considered when determining dosage. Data were obtained through interviews conducted in the first 12 to 48h and on the 5th day after MDA during household visits. RESULTS: A total of 487 and 365 individuals were interviewed in Areas I and II, respectively. The prevalence of ADRs in Area I (23.6; 95%CI: 19.1-29.5) was higher than in Area II (16.2; 95%CI:11.9-21.5)(p=0.0078). The prevalence of ADRs among females was higher than in males in Area I (p=0.0021). In Area II, no significant difference between the genders was observed (p=0.1840). Age was not associated with ADRs in either area. CONCLUSIONS: Adjusting MDA dosage schedules according to weight-for-age and sex may be may contribute to reduce the occurrence of adverse drug reactions in the population.

AIDS tendencies in São Mateus microregion, state of Espírito Santo, and Brazil from 1999 to 2008

INTRODUCTION: In Brazil, AIDS has been described as a multi-faceted pandemic. This study aimed to describe the trends of AIDS in São Mateus microregion, in Espírito Santo, and in Brazil, from 1999 to 2008. METHODS: Data were collected from the Notification Offences System, and a trend analysis was made. RESULTS: Microregion-based results are close to the state and national levels but with particular features that indicate the presence of regional sub-epidemics. CONCLUSIONS: Despite progress in nearly thirty years of the epidemic, AIDS remains an incurable disease, and prevention is still the best defense against it together with the implementation of specific public policies.

Rabies surveillance in bats in Northwestern State of São Paulo

Introduction Rabies is an important zoonosis that occurs in mammals, with bats acting as Lyssavirus reservoirs in urban, rural and natural areas. Rabies cases in bats have been recorded primarily in urban areas in Northwestern State of São Paulo since 1998. This study investigated the circulation of rabies virus by seeking to identify the virus in the brain in several species of bats in this region and by measuring rabies-virus neutralizing antibody levels in the hematophagous bat Desmodus rotundus. Methods From 2008 to 2012, 1,490 bat brain samples were sent to the Universidade Estadual Paulista (UNESP) Rabies Laboratory in Araçatuba, and 125 serum samples from vampire bats that were captured in this geographical region were analyzed. Results Rabies virus was detected in the brains of 26 (2%) of 1,314 non-hematophagous bats using the fluorescent antibody test (FAT) and the mouse inoculation test (MIT). None of the 176 hematophagous bat samples were positive for rabies virus when a virus detection test was utilized. Out of 125 vampire bat serum samples, 9 (7%) had levels of rabies virus neutralization antibodies (RVNAs) that were higher than 0.5IU/mL; 65% (81/125) had titers between 0.10IU/mL and 0.5IU/mL; and 28% (35/125) were negative for RVNAs using the simplified fluorescent inhibition microtest (SFIMT) in BHK21 cells. The observed positivity rate (1.7%) was higher than the average positivity rate of 1.3% that was previously found in this region. Conclusions The high percentage of vampire bats with neutralizing antibodies suggests that recent rabies virus exposure has occurred, indicating the necessity of surveillance measures in nearby regions that are at risk to avoid diffusion of the rabies virus and possible rabies occurrences.

Poor response to azithromycin in cutaneous leishmaniasis leading to a premature interruption of a multicentric phase III clinical trial in Brazil

Introduction Parenteral antimony-based compounds are still the standard of care for cutaneous leishmaniasis (CL) treatment in many countries, despite their high toxicity. Previous studies showed that oral azithromycin could be an option for CL treatment. The aim of this study was to evaluate efficacy and safety of oral azithromycin (AZ) for CL treatment compared with injectable meglumine antimoniate (MA). Methods This was a randomized, open-label, 2-arm, non-inferiority clinical trial. Treatment-naïve patients with localized CL were treated with MA (15mg/kg/day up to 1,215mg) or AZ (500mg/day) during 20 consecutive days. The primary efficacy end point was a CL cure 90 days after treatment completion. The analysis was performed with intention-to-treat (ITT) and per protocol (PP) analyses. After an anticipated interim analysis, the study was interrupted due to the high failure rate in the azithromycin group. Results Twenty-four volunteers were included in each group. The MA group had a higher cure rate than the AZ group with the ITT and PP analyses, which were 54.2% versus 20.8% [relative risk (RR) 1.97; 95% confidence intervals (95%CI) 1.13-3.42] and 72.2% versus 23.8% (RR 3.03; 95%CI 1.34-6.87), respectively. No unexpected adverse events were observed. Conclusions Azithromycin is ineffective for CL treatment and does not seem to have a role in the therapeutic arsenal for CL.

New strategies for active finding of leprosy cases in the Amazonian region

AbstractINTRODUCTION: The use of the Self-Image Form (SIF) expands the identification of active leprosy cases to neighbors of index cases.METHODS: The SIF was used to screen two groups: case (neighbors of index cases of leprosy) and control (individuals residing next to houses without leprosy) group. A specialist investigated suspected leprosy cases for disease confirmation.RESULTS: New cases of leprosy were diagnosed in the case group (n = 7, 8.6%), but not the control group.CONCLUSIONS: The new surveillance strategy is inexpensive, efficient, and feasible within a primary health strategy. Future studies can help improve the use of the SIF.

A organização molecular do Celulossoma: caracterização estrutural da proteína CipA e estudo da diversidade das interações coesina-doquerina

A celulose, principal componente da parede celular vegetal e o composto orgânico mais abundante da biosfera, possui inúmeras aplicações biotecnológicas. O microrganismo anaeróbio Clostridium thermocellum (C.thermocellum) tem sido alvo de grande interesse pela sua capacidade em degradar eficientemente a celulose e outros componentes da parede celular vegetal, por meio de um complexo multi-enzimático altamente eficiente, denominado de celulossoma. A montagem deste complexo ocorre através de uma proteína multi-modular denominada CipA. Esta proteína estrutural possui módulos não catalíticos (coesinas tipo I) que se ligam a módulos complementares (doquerinas tipo I) presentes nas enzimas celulolíticas modulares. A CipA possui ainda um módulo doquerina de tipo II que permite a ancoragem deste complexo multi-enzimático à parede celular da bactéria. Na presente dissertação foram utilizadas as metodologias de Cristalografia de Raios-X, para caracterizar a interação coesina-doquerina a nível atómico e molecular, e de Microarrays, com o intuito de estudar as possíveis especifidades e afinidades dessas interações. Com base na primeira técnica foram elucidadas as estruturas do módulo coesina C4 da CipA em complexo com a doquerina da enzima modular Xyn10B e do módulo coesina C9 isolado. As estruturas foram comparadas com o complexo do módulo coesina C2-doquerina Xyn10B já publicado. Esta análise encontra-se descrita no capítulo 3. Por último, a técnica de Microarrays, associada à eletroforese em gel de poliacrilamida em condições nativas, permitiu a caracterização das diferenças de afinidade e especificidade entre os vários pares coesina-doquerina dos celulossomas de C. thermocellum e de Rumminococcus flavefaciens (R. flavefaciens). As especificidades e afinidades dos módulos doquerina, dos celulossomas mencionados anteriormente estão descritas no capítulo 4.

O incumprimento do contrato de crédito ao consumo pelo consumidor

Consumer relations, established between the Consumer and the Creditor, which carry a consequent inequality of contractual positioning between the parties, have been pushing the legislator to adopt more rigid regulations with regard to lending for the purchase of goods or services of consum issues. In this sense, the Decree-Law 359/91 was approved, meanwhile repealed by the Decree-Law 133/2009, which regulates the consumer credit agreement’s regime in the portuguese legal system. Through this contract, the financier makes available to the consumer a certain amount of money, which the consumer must repay, plus the respective remuneration (interest) and other charges, according to a refund plan agreed by the parties. The consumer will be in delay if he breaches this stipulation. In case of default, the creditor, notwithstanding, can choose to wait for the performance by the debtor, promote the loss of benefit of the term or the termination of the contract. From the outset it would seem that, in one way or another, the financier, by imposing a forced shortening of the contract duration initially agreed, will lose the right to remuneration for the provision of capital agreed, but not verified. Nevertheless, unlike presently, the previous regime allowed the parties to rule otherwise, being permitted to agree to the payment of interest of outstanding installments. On the other hand, in the consumer credit contract the principle of freedom of contractual provision of the parties is strongly mitigated by the special legislation, which prevents the waiver of rights by the consumer, and by the regime of general contractual terms, which restricts the freedom of the financier to stipulate the contractual content freely and the freedom of the consumer to negotiate. For all these reasons, associated with the growing need of credit resource to satisfy their needs of consumption, it is confirm the relevance of legislative intervention on consumers protection in the context of hiring credit.

Prevalence of hypovitaminosis D and its association with oral lesions in HIV-infected Brazilian adults

Abstract: INTRODUCTION: This study assessed the prevalence of hypovitaminosis D and its association with oral candidiasis and clinical parameters of periodontitis (CPP) in HIV-infected patients. METHODS: Periodontal examinations for the 113 HIV-infected patients were recorded using the Community Periodontal Index. A cytological smear from the lateral borders of the tongue was performed to evaluate candidiasis. RESULTS: The frequency of hypovitaminosis D was 23.9%. In multivariate analysis, only the duration of exposure to HIV was associated with CPP [OR 4.72 (95% CI: 0.97-23.00)]. CONCLUSIONS: The prevalence of hypovitaminosis D was 23.9% and was not related with oral candidiasis or CPP.

Integrative literature review of the reported uses of serological tests in leprosy management

Abstract: An integrative literature review was conducted to synthesize available publications regarding the potential use of serological tests in leprosy programs. We searched the databases Literatura Latino-Americana e do Caribe em Ciências da Saúde, Índice Bibliográfico Espanhol em Ciências da Saúde, Acervo da Biblioteca da Organização Pan-Americana da Saúde, Medical Literature Analysis and Retrieval System Online, Hanseníase, National Library of Medicine, Scopus, Ovid, Cinahl, and Web of Science for articles investigating the use of serological tests for antibodies against phenolic glycolipid-I (PGL-I), ML0405, ML2331, leprosy IDRI diagnostic-1 (LID-1), and natural disaccharide octyl-leprosy IDRI diagnostic-1 (NDO-LID). From an initial pool of 3.514 articles, 40 full-length articles fulfilled our inclusion criteria. Based on these papers, we concluded that these antibodies can be used to assist in diagnosing leprosy, detecting neuritis, monitoring therapeutic efficacy, and monitoring household contacts or at-risk populations in leprosy-endemic areas. Thus, available data suggest that serological tests could contribute substantially to leprosy management.

A equidade na indeminização dos danos não patrimoniais

This study examines the quantification of compensation for non-pecuniary damage, awarded by means of judicial decisions based on equity, and seeks to verify whether such calculation safeguards legal certainty and predictability when applying the law, as well as whether it observes the principles of proportionality and equality. Firstly, the limits for discretionary judgment permitted to the judge were determined, by evaluating the criteria established under the law. Then, by examining the grounds of the judicial decisions in cases that had been selected beforehand, this study sought to detect operation modes in concrete considerations of equity used by judges. The examination of the grounds on which these judicial decisions are based permitted the comprehension of the calculation method used in each case and the observation that the criteria of compensatory nature, such as the extent of the damage and the respective consequences, assumed a primary role. Despite discrepancies in viewpoints with regard to certain issues of law, the jurisprudence examined reveals that great care is taken to consider the solutions reached in similar cases, in an attempt to ensure that the different criteria applied in the quantification of compensation are given uniform relevance. The comparison of decisions, reported to cases with similar legal contours, did not reveal relevant discrepancies in the calculation criteria used, nor are they disproportionate regarding the amount of compensation awarded, which means that resorting to equity, in determining the compensation to be awarded due to nonpecuniary damage, does not jeopardize legal certainty or predictability when applying the law, and observes the principle of proportionality, which is anchored in the constitutional principle of equality. The study performed, led to the conclusion that the grounds on which judicial decisions are based, by itemising the elements which are taken into account and the criteria adopted by the judge, allow these to be taken into consideration in similar cases, contributing towards uniform interpretation and application of the law, ensuring legal certainty and predictability when resorting to equity while quantifying compensation.

Sodium serum levels in hypoalbuminemic adults at general medical wards

Hypoalbuminemia may cause interstitial edema and hemodilution, which we hypothesized may influence serum sodium levels. Our purpose was to compare serum sodium levels of hospitalized adults with or without hypoalbuminemia. All sodium and albumin serum levels of 142 adults hospitalized at general medical wards over a six-month period were searched at a University Hospital mainframe computer. Relevant laboratory data and clinical details were also registered. Hypoalbuminemia was defined by serum albumin concentration < 3.3 g/dl Fisher, Mann-Whitney, and Student's t tests were applied to compare groups with or without hypoalbuminemia. Ninety-nine patients, classified as hypoalbuminemic, had lower blood hemoglobin (10.68 ± 2.62 vs. 13.54 ± 2.41), and sodium (135.1 ± 6.44 vs. 139.9 ± 4.76mEq/l) and albumin (2.74 ± 0.35 vs. 3.58 ± 0.28g/dl) serum levels than non-hypoalbuminemic (n=43). Pearson's coefficient showed a significant direct correlation between albumin and sodium serum levels (r=0.40) and between serum albumin and blood hemoglobin concentration (r=0.46). Our results suggest that hypoalbuminemic adults have lower serum sodium levels than those without hypoalbuminemia, a phenomenon that may be at least partially attributed to body water retention associated with acute phase response syndrome.
