Resumo Objetivou-se comparar características sociodemográficas, padrões de consumo de substâncias, comportamento sexual, utilização de serviços de saúde e envolvimento criminal de usuários, domiciliados e em situação de rua. Dados secundários do Inquérito Nacional sobre Uso do Crack, utilizando análise discriminante e de correspondência para comparar características dos usuários segundo condição de moradia. O modelo final de regressão logística evidenciou associações entre “situação de rua” e ser do sexo feminino, trabalho descontínuo, consumo de tabaco e “oxi” nos últimos 30 dias, uso de serviços de alimentação gratuita, baixo acesso a tratamento e frequentes detenções no último ano. Na análise de correspondência observou-se proximidade no espaço analítico de “troca de sexo por drogas”, “trabalho informal”, “idade” >31 anos, “baixo acesso a CAPS-ad”, “problemas com a justiça criminal” e “sexo feminino” com os usuários de crack desabrigados. Pouco se sabe sobre usuários de crack em contexto na região Nordeste do Brasil. Os resultados evidenciam dois subgrupos com características específicas. Enquanto os domiciliados têm acesso aos serviços de CAPS-ad e outras clínicas especializadas, os usuários em situação de rua relataram, basicamente, acesso a serviços de alimentação gratuita e redução de danos.

Abstract We compared sociodemographic characteristics, substance use patterns, sexual behavior, use of health services, and criminal records of homeless vs. domiciled users. Data are from the Brazilian National Survey on Crack Use. A discriminant model and correspondence analysis cross-compared characteristics of users according to their housing status. The logistic model revealed associations between “living in the streets” and female gender and intermittent work. “Homelessness” was also associated with the use of tobacco and “oxi” in the previous 30 days, reliance on soup kitchens, low access to public mental health services, and arrests in the previous year. Correspondence analysis highlighted the spatial proximity of the variables as follows: “having traded sex for drugs”, “informal work”, “age 31 years or older”, “access to public mental health services”, “problems with law enforcement”, and female gender with homeless crack users. People who smoke crack cocaine in Northeast Brazil are seldom studied. Their profiles, stratified according to their housing conditions, show subgroups with specific characteristics. While domiciled users have access to specialized clinics, homeless users basically reported access to free food and harm reduction services.

BACKGROUND The lepromatous pole is a stigmatising prototype for patients with leprosy. Generally, these patients have little or no symptoms of peripheral nerve involvement at the time of their diagnosis. However, signs of advanced peripheral neuropathy would be visible during the initial neurological evaluation and could worsen during and after multidrug therapy (MDT). Disabilities caused by peripheral nerve injuries greatly affect these patients’ lives, and the pathophysiological mechanisms underlying nerve damage remain unclear. OBJECTIVES To evaluate the outcome of peripheral neuropathy in patients with lepromatous leprosy (LL) and persistent neuropathic symptoms years after completing MDT. METHODS We evaluated the medical records of 14 patients with LL who underwent nerve biopsies due to worsening neuropathy at least four years after MDT. FINDINGS Neuropathic pain developed in 64.3% of the patients, and a neurological examination showed that most patients had alterations in the medium- and large-caliber fibers at the beginning of treatment. Neurological symptoms and signs deteriorated despite complete MDT and prednisone or thalidomide use for years. Nerve conduction studies showed that sensory nerves were the most affected. MAIN CONCLUSIONS Patients with LL can develop progressive peripheral neuropathy, which continues to develop even when they are on long-term anti-inflammatory and immunosuppressive therapy.

BACKGROUND CD64 (FcγR1) is a high-affinity receptor for monomeric IgG1 and IgG3. Circulating neutrophils express very low amounts of CD64 on their surface. OBJECTIVES Our primary aim was to investigate the utility of neutrophil CD64 surface expression as a biomarker of active pulmonary tuberculosis (TB). We hypothesised that elevated neutrophil CD64 expression in TB infection would be associated with interferon gamma (IFN-γ) as an inducer of CD64 expression. METHODS The expression level of CD64 per neutrophil (PMN CD64 index) was quantitatively measured with flow cytometry using a Leuko64 kit in samples from patients with TB and latent TB infection (LTBI) as well as healthy controls, as part of a prospective cohort study in Brazil. FINDINGS The PMN CD64 index in patients with TB was higher than that in healthy controls and LTBI. Receiver operating characteristic curve analyses determined that the PMN CD64 index could discriminate patients with TB from those with LTBI and healthy individuals. PMN CD64 index levels returned to baseline levels after treatment. CONCLUSIONS The positive regulation of CD64 expression in circulating neutrophils of patients with active TB could represent an additional biomarker for diagnosis of active TB and could be used for monitoring individuals with LTBI before progression of TB disease.

Resumo Trabalhos demonstraram que a distribuição geográfica da hanseníase está relacionada a diferentes fatores socioeconômicos. O objetivo deste artigo é estudar a distribuição geográfica da hanseníase no estado do Rio de Janeiro. Os casos de hanseníase notificados no período 2001-2012 foram mapeados segundo município. Foram calculados indicadores epidemiológicos e socioeconômicos. Utilizou-se o programa ArcMap para a construção dos mapas e o Terra View para o cálculo de taxa bayesiana. Observou-se que a hanseníase apresenta-se em níveis hiperendêmicos, especialmente na região metropolitana. No entanto, observa-se também uma redução do coeficiente de detecção no período mais recente do estudo. Em municípios da região metropolitana e da região noroeste a detecção em menores de 15 anos é elevada, indicando situação de transmissão ativa. Em municípios da região centro-sul e especialmente na baixada litorânea, observou-se elevada proporção de casos diagnosticados com grau II de incapacidade, refletindo alto índice de diagnóstico tardio. Não foi observada correlação linear entre os indicadores socioeconômicos e a detecção da hanseníase. Esses resultados contribuem para a análise da distribuição geográfica da hanseníase, importante para a identificação de áreas para alocação de recursos, visando controle e eliminação da doença.

Abstract Studies have demonstrated that the geographical distribution of leprosy is related to different socioeconomic factors. This article aims to study the geographical distribution of leprosy in the state of Rio de Janeiro. The cases of leprosy reported in the 2001-2012 period were mapped according to municipality. Epidemiological and socioeconomic indicators were calculated. The ArcMap program was used for the construction of maps and Earth View to calculate the Bayesian rate. It was observed that leprosy is presented in hyper-endemic levels especially in the metropolitan area. However, there is also a reduction of the detection rate in the most recent study period. In municipalities in the metropolitan region and the north western region detection in children under 15 is high, indicating an active transmission situation. In municipalities in the south-central region and especially in the coastal region, there was a high proportion of cases diagnosed with level II disability, reflecting late diagnosis. There was no linear correlation between socioeconomic indicators and leprosy rate. These results contribute to the analysis of the geographical distribution of leprosy, important for the identification of areas for resource allocation, aiming to control and eliminate the disease.

Contact surveillance is an important strategy to ensure effective early diagnosis and control of leprosy; passive detection may not be as efficient because it is directly tied to the ready availability of heath care services and health education campaigns. The aim of this study was to reinforce that contact surveillance is the most effective strategy for the control of leprosy. The analysed data were obtained from a cohort of contacts and cases diagnosed through a national referral service for leprosy. We analysed data from patients diagnosed between 1987-2010 at the Souza Araújo Ambulatory in Rio de Janeiro. Epidemiological characteristics of leprosy cases diagnosed through contact surveillance and characteristics of passively detected index cases were compared using a conditional logistic regression model. Cases diagnosed by contact surveillance were found earlier in the progression of the disease, resulting in less severe clinical presentations, lower levels of initial and final disability grades, lower initial and final bacterial indices and a lower prevalence of disease reaction. In this respect, contact surveillance proved to be an effective tertiary prevention strategy, indicating that active surveillance is especially important in areas of high endemicity, such as Brazil.

Contact surveillance is a valuable strategy for controlling leprosy. A dynamic cohort study of leprosy contacts was initiated in 1987 at Oswaldo Cruz Foundation. The objective of this work was to review the data on the major risk factors leading up to the infectious stage of the disease, estimate incidence rates of leprosy in the cohort and characterise the risk factors for the disease among the contacts under surveillance. The incidence rate of leprosy among contacts of leprosy patients was estimated at 0.01694 cases per person-year in the first five years of follow-up. The following factors were associated with acquiring the disease: (i) not receiving the BCG vaccine, (ii) a negative Mitsuda reaction and (iii) contact with a patient with a multibacillary clinical form of leprosy. The contacts of index patients who had high bacilloscopic index scores > 1 were at especially high risk of infection. The following factors were associated with infection, which was defined as a seropositive reaction for anti-phenolic glicolipid-1 IgM: (i) young age (< 20 years), (ii) a low measured Mitsuda reaction (< 5 mm) and (iii) contact with an index patient who had a high bacilloscopic index. BCG vaccination and re-vaccination were shown to be protective among household contacts. The main conclusions of this study indicate an urgent need for additional leprosy control strategies in areas with a high incidence of the disease.

O objetivo deste trabalho foi comparar dados epidemiológicos de pacientes de hanseníase residentes em dois municípios com perfil socioeconômico e nível de endemicidade diferentes e que foram acompanhados em um mesmo centro de referência. Foi realizado um estudo descritivo dos dados de pacientes tratados no ambulatório Souza Araújo, 1986 a 2008, residentes nos municípios do Rio de Janeiro (n = 1353) e Duque de Caxias (n = 336). Entre os pacientes desta cidade, em comparação com os da outra, observou-se maior proporção de casos: com idade inferior a 15 anos, multibalicares, com maior índice baciloscópico (IB) inicial, e detectados através da vigilância de contatos. Os pacientes de Duque de Caxias apresentaram menor renda média e nível de escolaridade. Não foram observadas diferenças estatisticamente significativas quanto ao sexo, grau de incapacidade inicial, reação no diagnóstico, IB final, abandono e regularidade do tratamento. As diferenças encontradas entre os pacientes acompanhados em um mesmo centro de referência poderiam estar, em parte, relacionadas a diferenças contextuais existentes entre os municípios. Por outro lado, observou-se que a oferta de tratamento e acompanhamento podem minimizar o efeito que os fatores contextuais apresentam sobre os desfechos de saúde.

The scope of this study was to compare epidemiological data on leprosy patients living in two cities with different socioeconomic and endemic profiles that were monitored in a single center of reference. A descriptive study was made of data from patients in the Souza Araújo Outpatient facility treated in the period 1986-2008, who were resident in the cities of Rio de Janeiro = 1353) and Duque de Caxias (n = 336). Results: Among patients from Duque de Caxias, in comparison with patients from Rio de Janeiro, there was a higher proportion of cases: below the age of 15 years, multibacillary, higher initial bacilloscopic index (BI) and cases detected through surveillance of contacts. Patients in Duque de Caxias had lower average incomes and education levels. There were no statistically significant differences regarding gender, disability level, reaction in the diagnosis, final BI, bandonment and regularity of treatment. The differences found between the patients monitored in a single center of reference, could be partly related to contextual differences between the municipalities. On the other hand, it was observed that the provision of treatment and monitoring can minimize the effect of different contextual factors on health outcomes.

OBJECTIVE: To analyze a profile of patients treated at a national leprosy outpatient referral clinic in metropolitan Rio de Janeiro, Brazil, over a period of more than two decades, and the subgroup of nationally registered leprosy cases from the same residential area, as well as all registered cases statewide. METHODS: An observational, descriptive analysis was carried out for patients treated from 1986 to 2007 at the Souza Araújo Outpatient Clinic (Ambulatório Souza Araújo, ASA), a national referral center for the diagnosis and treatment of leprosy at the Oswaldo Cruz Foundation (Fiocruz) that serves clients from the city of Rio de Janeiro and other municipalities in the metropolitan area of Rio de Janeiro State. Demographic and clinical data for the subgroup of leprosy cases registered with Brazil's National Disease Notification System (Sistema Nacional de Informação de Agravos de Notificação, SINAN) between 2001 and 2007 and residing in the same municipalities as the ASA patients, and for all registered cases statewide, were also analyzed. RESULTS: Among the ASA patients, there was a decrease in average family income (from 3.9 to 2.7 times the minimum salary between the periods 1998-2002 and 2003-2007); the proportion of multibacillary (MB) patients (from 52.7% to 46.9%); and the proportion of patients younger than 15 years old (from 12.8% to 8.7%). Among the MB patients, the average initial and final bacilloscopic indices were significantly higher in 2003-2007. Compared with the SINAN cases, more ASA cases involved disability and were younger than 15 years old. CONCLUSIONS: Patients living with leprosy in the metropolitan area of the state of Rio de Janeiro belong to the most deprived social strata and have not benefited from the overall improvement in socioeconomic conditions in Brazil.

OBJETIVO: Analizar el perfil de los enfermos tratados en un servicio nacional de remisión de pacientes ambulatorios con lepra ubicado en la zona metropolitana de Río de Janeiro, Brasil, durante más de dos decenios, y el subgrupo de casos de lepra registrados a nivel nacional de la misma zona de residencia, así como todos los casos registrados a nivel estatal. MÉTODOS: Se llevó a cabo un análisis observacional y descriptivo de los pacientes tratados desde 1986 a 2007 en el servicio ambulatorio Souza Araújo (ASA), un centro de remisión nacional para el diagnóstico y el tratamiento de la lepra en la Fundación Oswaldo Cruz, que atiende a pacientes de la ciudad de Río de Janeiro y de otros municipios de la zona metropolitana del Estado de Río de Janeiro. También se analizaron los datos demográficos y clínicos del subgrupo de casos de lepra registrados con el Sistema Nacional de Notificación de Enfermedades del Brasil (SINAN) entre el 2001 y el 2007 residentes en los mismos municipios que los pacientes atendidos en el ASA, y de todos los casos registrados a nivel estatal. RESULTADOS: En los pacientes atendidos en el ASA hubo una disminución en los ingresos familiares promedio (de 3,9 a 2,7 veces el sueldo mínimo entre los períodos 1998-2002 y 2003-2007), en la proporción de pacientes multibacilares (de 52,7% a 46,9%), y en la proporción de pacientes menores de 15 años de edad (de 12,8% a 8,7%). En los pacientes multibacilares, los índices baciloscópicos promedio inicial y final fueron significativamente mayores en el período 2003-2007. En comparación con los casos del SINAN, en el ASA hubo más casos con discapacidad y en menores de 15 años de edad. CONCLUSIONES: Los pacientes con lepra de la zona metropolitana del Estado de Río de Janeiro pertenecen al estrato social más bajo y no se han beneficiado con el mejoramiento general de la situación socioeconómica en el Brasil.

Nerve biopsy examination is an important auxiliary procedure for diagnosing pure neural leprosy (PNL). When acid-fast bacilli (AFB) are not detected in the nerve sample, the value of other nonspecific histological alterations should be considered along with pertinent clinical, electroneuromyographical and laboratory data (the detection of Mycobacterium leprae DNA with polymerase chain reaction and the detection of serum anti-phenolic glycolipid 1 antibodies) to support a possible or probable PNL diagnosis. Three hundred forty nerve samples [144 from PNL patients and 196 from patients with non-leprosy peripheral neuropathies (NLN)] were examined. Both AFB-negative and AFB-positive PNL samples had more frequent histopathological alterations (epithelioid granulomas, mononuclear infiltrates, fibrosis, perineurial and subperineurial oedema and decreased numbers of myelinated fibres) than the NLN group. Multivariate analysis revealed that independently, mononuclear infiltrate and perineurial fibrosis were more common in the PNL group and were able to correctly classify AFB-negative PNL samples. These results indicate that even in the absence of AFB, these histopathological nerve alterations may justify a PNL diagnosis when observed in conjunction with pertinent clinical, epidemiological and laboratory data.

Usuários de drogas (UD) são uma população marginalizada e sob risco para hepatites virais que raramente acessam tratamento. Foi utilizado inquérito com 110 UD com Hepatite crônica e 15 entrevistas em profundidade com profissionais e gestores de saúde. A maioria dos entrevistados é homem, não branco, com baixa escolaridade, desempregado e com renda < salário mínimo. Nos últimos 6 meses, 61,8% usaram cocaína inalada e 64,7% uma vez por semana ou mais. Dos participantes, 50% tiveram relações sexuais com parceiros estáveis e 38,3% com parceiros ocasionais nunca/quase nunca usando preservativos. Preditores de busca por tratamento para dependência química incluem: raça/cor branca (OR:5.5), ter ensino médio (OR:8.7) e estar empregado (OR:5.7). 80,9% dos participantes buscou tratamento para hepatite, o acesso a serviços mais acolhedores é determinante para esse comportamento (OR:3.6). Oportunidades perdidas para tratamento de hepatite estão associadas a barreiras estruturais (inadequado apoio político/financeiro aos programas) e barreiras individuais (dependência química severa e baixa aderência). Aqueles que mais precisam de tratamento possuem menor chance de obtê-lo, salientando a importância de renovar estratégias para responder à epidemia de hepatite entre usuários de drogas empobrecidos e seus parceiros sexuais.

Drug users (DU) are a marginalized group and at risk for viral hepatitis, who seldom access health services. A cross-sectional survey was conducted with 111 DU with chronic HBV/HCV and 15 in-depth interviews with health professionals/policymakers in Rio de Janeiro, Brazil. Most interviewees were male, non-white, with a low educational background, unemployed and/or living on less than $245 a month (minimun wage). In the last 6 months, 61.8% of interviewees snorted cocaine, 64.7% at least once a week. Half of the interviewees had a stable partner and 38.3% of those with occasional partners never/almost never using condoms. Addiction treatment seeking was found to be associated with: being white (OR:5.5), high-school degree (OR:8.7), and employment (OR:5.7). Hepatitis treatment seeking was high (80.9%), and access to low-threshold, user-friendly health services was key for treatment seeking behaviors (OR:3.6). Missed opportunities for hepatitis treatment seem to be associated with structural (uneven political/financial support to hepatitis programs) and patient-related barriers (severe addiction and non-adherence). Those most in need were less likely to access treatment, calling for renewed strategies, in order to curb hepatitis among impoverished drug users and their sexual partners.

OBJETIVO: Analisar os padrões de consumo de álcool e drogas de uma amostra representativa da população urbana brasileira na sua inter-relação com a saúde sexual e reprodutiva. MÉTODOS: Dados de inquérito de base populacional, de abrangência nacional, com plano amostral complexo, realizado em 2005. Foram entrevistados 5.040 indivíduos de ambos os sexos, na faixa etária de 16 a 65 anos. Analisaram-se questões relativas consumo de álcool e drogas e comportamento sexual. Utilizou-se análise bivariada e multivariada. RESULTADOS: O álcool foi a substância mais freqüentemente utilizada, com relato de uso regular, na vida, por 18% dos entrevistados. O consumo de drogas ilícitas foi referido por 9% dos entrevistados, especialmente, maconha e cocaína aspirada, com uso de drogas injetáveis infreqüente. Observou-se declínio do consumo de cocaína aspirada e incremento do uso de maconha (nos últimos 12 meses), comparados a resultados de pesquisa similar realizada em 1998. Histórico de abuso sexual constituiu fator de risco do consumo de drogas e uso regular de álcool. A referência por parte do entrevistado ao papel da religião na sua formação, ser branco e do sexo feminino se mostraram protetores frente ao consumo regular de álcool, particularmente prevalente entre homens mais velhos. As opções de lazer e a ausência de práticas religiosas atuais se mostraram associadas ao consumo de drogas. CONCLUSÕES: O consumo de álcool, regular ou não, é prevalente na população urbana brasileira, enquanto o uso de drogas injetáveis se mostrou raro. Ao longo da última década observou-se declínio no consumo de cocaína. Histórico de abuso sexual se mostrou central ao consumo posterior de drogas e álcool.

OBJECTIVE: To assess alcohol and drug use in a representative sample of the urban Brazilian population and their correlation with sexual and reproductive health. METHODS: Data from a national population-based survey with a complex sampling, performed in 2005 was used. A total of 5,040 individuals from both genders, in the age group from 16 to 65 years old, were interviewed. Issues regarding drug and alcohol use and sexual behavior were assessed. Bivariate and multivariate analyses were used. RESULTS: Alcohol was the most frequently used substance, with reports of regular use in the lives of 18% of interviewees. Use of illegal drugs was mentioned by 9% of the interviewees especially marijuana and snorted cocaine; injected drugs use was not frequent. There was a decrease in snorted cocaine use and an increase in marijuana use (in the last 12 months), compared to results of a similar survey conducted in 1998. History of sexual abuse was a risk factor for drug use and regular alcohol use. Interviewees mentioning the role of religion in their background, being White, and female were less likely to use alcohol in a regular way, which is especially prevalent among elderly males.Leisure activities and absence of current religious practice were associated with drug use. CONCLUSIONS: The regular or irregular alcohol use is prevalent in the urban Brazilian population, whereas injected drug use is rare. Over the last decade there was a decline in cocaine use. A history of sexual abuse was central to later use of alcohol and drugs.
