Cenário epidemiológico da hanseníase e diferenças por sexo / Epidemiological scenario of leprosy and sex differences

Objetivo: Descrever o cenário epidemiológico da hanseníase segundo as características clínicas e demográficas entre indivíduos dos sexos feminino e masculino. Métodos: Trata-se de um estudo ecológico de série temporal. Avaliaram-se dados de pacientes notificados no Sistema de Informações de Agravos de Notificação (Sinan) durante o período de 2014 a 2017 no município de Paulo Afonso, na Bahia. Resultados: Foram notificados 130 casos novos, com taxa de detecção média nas mulheres de 14,7±5,6 por 100 mil habitantes, ou seja, valores bem acima da média estadual e nacional (p=0,011). Além disso, observou-se predominância de casos multibacilares em homens e paucibacilares em mulheres (p>0,0001). A faixa etária mais acometida foi entre 35 e 64 anos (53,1%), independentemente do sexo. Conclusão: A hanseníase apresentou-se com grau de endemicidade muito alto e acometendo prioritariamente as mulheres. Portanto, há necessidade urgente de elaboração de políticas públicas mais direcionadas ao enfrentamento da doença no município. (AU)

Objective: To describe the epidemiological scenario of leprosy according to the clinical and demographic characteristic among men and women. Methods: This is an ecological time-series study. Data from patients notified in the Sistema de Informações de Agravos de Notificação (Sinan) were evaluated from 2014 to 2017 in the municipality of Paulo Afonso, in Bahia. Results: A total of 130 new cases were reported, with an average detection rate in women of 14.7±5.6 per 100 thousand inhabitants, that is, values well above the state and national average (p=0.011). In addition, there is a predominance of multibacillary cases in men and paucibacillary cases in women (p>0.0001). The most affected age group was between 35 and 64 years old (53.1%), regardless of sex. Conclusion: Leprosy had a very high degree of endemicity affecting primarily women. Therefore, there is an urgent need to develop public policies that are more focused on coping with the disease in the municipality. (AU)

Carotid intima-media thickness and epicardial fat thickness predict precoronary artery disease status in psoriasis.

BACKGROUND: Carotid intima-media thickness test is a surrogate marker of subclinical atherosclerosis. Epicardial fat thickness is an early marker of coronary artery disease. Several studies have noted that psoriasis patients have an increased risk of coronary artery disease. In the present study, we attempted to see any variation in carotid intima-media thickness and epicardial fat thickness in psoriasis patients when compared to controls. AIMS: 1) To determine the carotid intima-media thickness and epicardial fat thickness in psoriatic patients and healthy controls. 2) To evaluate the association between carotid intima-media thickness and epicardial fat thickness in psoriasis patients. METHODS: A hospital-based study with 100 subjects (50 with psoriasis and 50 healthy controls) was conducted in the Dermatology Outpatient Department of Justice KS Hegde Charitable Hospital, a unit of KS Hegde Medical Academy affiliated to NITTE (Deemed to be University) Mangaluru. A detailed history and examination including body mass index, psoriasis area and severity index were done. Carotid ultrasound was done to measure carotid intima-media thickness and transthoracic echocardiography was done to assess epicardial fat thickness in both cases and controls. Independent sample t-test, Pearson rank correlation (r) coefficient were used for statistical analysis. P-value <0.05 was considered statistically significant. IBM Statistical Package for the Social Sciences version 22 Armonk, NY: IBM Corp was used for statistical analysis. RESULTS: Mean carotid intima-media thickness in the right carotid ([0.51 ± 0.1mm vs 0.47 ± 0.1 mm] [P = 0.038]) and left carotid ([0.53 ± 0.12 mm vs 0.48 ± 0.1 mm] [P = 0.041]) were significantly increased in psoriasis patients than in controls. Mean epicardial fat thickness was significantly increased ([1.76 ± 0.66 mm vs. 1.49 ± 0.47 mm] ([P = 0.020]) in patients with psoriasis when compared with the controls. Epicardial fat thickness was positively correlated with carotid intima-media thickness in patients with psoriasis. LIMITATIONS: The cross-sectional design of the study, smoking among study subjects, inter and intraobserver variability of measurement of epicardial fat thickness and carotid intima-media thickness. CONCLUSION: Carotid intima-media thickness and epicardial fat thickness were increased in psoriasis patients when compared with healthy controls. Epicardial fat thickness was positively correlated with carotid intima-media thickness in cases.

Family dermatology life quality index in patients with pemphigus vulgaris: A cross-sectional study.

BACKGROUND AND AIMS: Pemphigus vulgaris is a rare autoimmune intraepidermal vesiculobullous disease involving the skin and mucosa. It impacts the quality of life of both patients and their families. METHODS: A total of 70 patients with pemphigus vulgaris (either outpatient or hospitalized) were enrolled using the simple sampling method between 2016 and 2017 from the dermatology clinic at Faghihi Hospital, Shiraz, Iran. A validated Persian version of the Family Dermatology Life Quality Index (FLDQI) questionnaire was filled by a family caregiver. The questionnaire contained 10 items assessing the quality of life of the family. Demographic variables were recorded in a separate form. RESULTS: The mean age of the patients was 51 ± 11.3 years and that of the family caregivers was 32 ± 8.8 years. The FLDQI score was higher (poorer quality of life) if the patient was male, older, had shorter disease duration or had fewer disease recurrences (P = 0.046, 0.01, 0.001 and >0.001, respectively). Higher scores were also obtained in the less-educated caregivers (P = 0.026) but there was no association with either gender or age (P = 0.399, 0.1). CONCLUSION: Pemphigus vulgaris significantly affects the Family Dermatology Life Quality Index. Education and counseling of family caregivers by various support groups such as Pemphigus Family Associations could be effective in improving the quality of life of the caregivers. LIMITATIONS: This study did not assess the effect of comprising domain analysis, severity of disease, patients' Dermatology Life Quality Index (DLQI), mucosal involvement, response to treatment, outpatient or admitted status, socioeconomic status, or the quality of life among the various family members.

Autochthonous leprosy in Spain: Has the transmission of Mycobacterium leprae stopped?

BACKGROUND: The aim of this study is to explore whether transmission of M. leprae has ceased in Spain, based upon the patterns and trends of notified cases. METHODOLOGY: Data on new cases reported to the National Leprosy Registry between the years 2003-2018 were extracted. In absence of detailed travel history, cases were considered "autochthonous" or "imported" based on whether they were born within or outside of Spain. These data were analyzed by age, sex, clinical type, country of origin, and location of residence at time of notification. PRINCIPAL FINDINGS: Data were available on 61 autochthonous and 199 imported cases since 2003. There were clear declines in incidence in both groups, and more imported than autochthonous cases every year since 2006. Autochthonous cases were more frequently multibacillary and had older age at diagnosis compared to imported cases. All the autochthonous cases had been born before 1985 and were more than 25 years old at diagnosis. Male-to-female ratio increased with time for autochthonous cases (except for the last time period). The imported cases originated from 25 countries, half of them from Brasil and Paraguay. Autochthonous cases were mainly distributed in the traditionally endemic regions, especially Andalucía and the eastern Mediterranean coast. CONCLUSIONS: Autochthonous and imported cases have different epidemiologic patterns in Spain. There was a clear decline in incidence rates of autochthonous disease, and patterns consistent with those reported from other regions where transmission has ceased. Autochthonous transmission of M. leprae is likely to have now effectively stopped in Spain.

Trends and forecasts of leprosy for a hyperendemic city from Brazil's northeast: Evidence from an eleven-year time-series analysis.

This study's objective was to estimate the temporal trends of leprosy according to sex and age groups, as well as to estimate and predict the progression of the disease in a hyperendemic city located in the northeast of Brazil. This ecological time-series study was conducted in Imperatriz, Maranhão, Brazil. Leprosy cases diagnosed between 2006 and 2016 were included. Detection rates stratified by sex and age groups were estimated. The study of temporal trends was accomplished using the Seasonal-Trend Decomposition method and temporal modeling of detection rates using linear seasonal autoregressive integrated moving average model according to Box and Jenkins method. Trend forecasts were performed for the 2017-2020 period. A total of 3,212 cases of leprosy were identified, the average incidence among men aged between 30 and 59 years old was 201.55/100,000 inhabitants and among women in the same age group was 135.28/100,000 inhabitants. Detection rates in total and by sex presented a downward trend, though rates stratified according to sex and age presented a growing trend among men aged less than 15 years old and among women aged 60 years old or over. The final models selected in the time-series analysis show the forecasts of total detection rates and rates for men and women presented a downward trend for the 2017-2020 period. Even though the forecasts show a downward trend in Imperatriz, the city is unlikely to meet a significant decrease of the disease burden by 2020.

Incidence of and Factors Associated With Leprosy Among Household Contacts of Patients With Leprosy in Brazil.

Importance: Despite progress toward reducing global incidence, leprosy control remains a challenge in low- and middle-income countries. Objective: To estimate new case detection rates of leprosy among household contacts of patients with previously diagnosed leprosy and to investigate its associated risk factors. Design, Setting, and Participants: This population-based cohort study included families registered in the 100 Million Brazilian Cohort linked with nationwide registries of leprosy; data were collected from January 1, 2007, through December 31, 2014. Household contacts of patients with a previous diagnosis of leprosy from each household unit were followed up from the time of detection of the primary case to the time of detection of a subsequent case or until December 31, 2014. Data analysis was performed from May to December 2018. Exposures: Clinical characteristics of the primary case and sociodemographic factors of the household contact. Main Outcomes and Measures: Incidence of leprosy, estimated as the new case detection rate of leprosy per 100 000 household contacts at risk (person-years at risk). The association between occurrence of a subsequent leprosy case and the exposure risk factors was assessed using multilevel mixed-effects logistic regressions allowing for state- and household-specific random effects. Results: Among 42 725 household contacts (22 449 [52.5%] female; mean [SD] age, 22.4 [18.5] years) of 17 876 patients detected with leprosy, the new case detection rate of leprosy was 636.3 (95% CI, 594.4-681.1) per 100 000 person-years at risk overall and 521.9 (95% CI, 466.3-584.1) per 100 000 person-years at risk among children younger than 15 years. Household contacts of patients with multibacillary leprosy had higher odds of developing leprosy (adjusted odds ratio [OR], 1.48; 95% CI, 1.17-1.88), and the odds increased among contacts aged 50 years or older (adjusted OR, 3.11; 95% CI, 2.03-4.76). Leprosy detection was negatively associated with illiterate or preschool educational level (adjusted OR, 0.59; 95% CI, 0.38-0.92). For children, the odds were increased among boys (adjusted OR, 1.70; 95% CI, 1.20-2.42). Conclusions and Relevance: The findings in this Brazilian population-based cohort study suggest that the household contacts of patients with leprosy may have increased risk of leprosy, especially in households with existing multibacillary cases and older contacts. Public health interventions, such as contact screening, that specifically target this population appear to be needed.

Leprosy in the elderly population of an endemic state in the Brazilian Northeast (2001-2017): epidemiological scenario

Abstract This ecological study aims to analyze both the tendency and the characteristics of leprosy in the elderly population in the state of Bahia, 2001-2017. The tendency was analyzed through joinpoint regression. Epidemiological variables were also included in the study. The average detection rate was 38.73/100,000, with prevalence of men (45.19/100,000). A downward trend occurred in both genders, from 2004, with a greater magnitude in women (annual percent change [APC] = −3.4%). Men presented higher proportions of the multibacillary forms and physical disabilities. The epidemiological scenario indicates the need of implementation of actions that stimulate early diagnosis and treatment of the elderly population.

Pleural fluid ADA activity in tuberculous pleurisy can be low in elderly, critically ill patients with multi-organ failure.

BACKGROUND: Adenosine deaminase (ADA) activity is typically elevated in patients with tuberculous pleural effusion (TPE), but low ADA has occasionally been reported in patients with TPE. The characteristics of these patients are not well-known, and erroneous exclusion of the possibility of TPE can result in a delayed diagnosis. This study investigated the characteristics of patients with TPE who had low ADA activity. METHODS: We retrospectively reviewed patients with microbiologically or pathologically confirmed TPE between 2012 to 2018 in a tertiary hospital in South Korea. Patients were categorised into two groups: high ADA (≥40 IU/L) and low ADA (< 40 IU/L). Clinical characteristics and Sequential Organ Failure Assessment (SOFA) scores were compared between groups. RESULTS: A total of 192 patients with TPE were included; 36 (18.8%) had ADA < 40 IU/L with a mean ADA activity level of 20.9 (±9.2) IU/L. Patients with low ADA were older (75.3 vs. 62.0 years, p < 0.001) and had a lower mean lymphocyte percentage (47.6% vs. 69.9%, p < 0.001) than patients with high ADA. Patients in the low ADA group had a significantly higher mean SOFA score (2.31 vs. 0.68, p < 0.001), and patients with organ dysfunction were significantly more common in the low ADA group (p < 0.001). Patients with 2 or ≥ 3 organ dysfunctions constituted 19.4 and 13.9% of the patients in the low ADA group, whereas they constituted 7.1 and 1.3% of the patients in the high ADA group (p < 0.001). Multivariate logistic regression analyses showed that older age (odds ratio = 1.030, 95% confidence interval 1.002-1.060, p = 0.038) and a higher SOFA score (odds ratio = 1.598, 95% confidence interval 1.239-2.060, p < 0.001) were significantly associated with low ADA activity in patients with TPE. CONCLUSIONS: ADA activity can be low in patients with TPE who are elderly, critically ill, and exhibit multiorgan failure. Low ADA activity cannot completely exclude the diagnosis of TPE, and physicians should exercise caution when interpreting pleural fluid exams.

Leprosy in the elderly population of an endemic state in the Brazilian Northeast (2001-2017): epidemiological scenario.

This ecological study aims to analyze both the tendency and the characteristics of leprosy in the elderly population in the state of Bahia, 2001-2017. The tendency was analyzed through joinpoint regression. Epidemiological variables were also included in the study. The average detection rate was 38.73/100,000, with prevalence of men (45.19/100,000). A downward trend occurred in both genders, from 2004, with a greater magnitude in women (annual percent change [APC]=-3.4%). Men presented higher proportions of the multibacillary forms and physical disabilities. The epidemiological scenario indicates the need of implementation of actions that stimulate early diagnosis and treatment of the elderly population.

Inequalities in health by regime of affiliation to the health system in events of obligatory notification, Colombia, 2015 / Desigualdades en salud según régimen de afiliación y eventos notificados al Sistema de Vigilancia (Sivigila) en Colombia, 2015

Introduction: Inequalities in the health field are caused by the differences in the social and economic conditions, that influence the disease risk and the measures taken to treat the disease. Objective: We aimed to estimate the social inequalities in health in Colombia, according to the type of affiliation to the health system as a proxy of socioeconomic status. Materials and methods: We conducted a retrospective descriptive analysis calculating incidence rates age and sex adjusted for all mandatory reporting events using the affiliation regime (subsidized and contributory) as a socioeconomic proxy. Estimates were made at departmental level for 2015. Social inequalities were calculated in terms of absolute and relative gaps. Results: We found social inequalities in the occurrence of mandatory reporting events in population affiliated to the Colombian subsidized regime (poor population). In this population, 82.31 cases of Plasmodium falciparum malaria per 100,000 affiliates were reported more than those reported in the contributory regime. Regarding the relative gap, belonging to the subsidized regime increased by 31.74 times the risk of dying from malnutrition in children under 5 years of age. Other events such as those related to sexual and reproductive health (maternal mortality, gestational syphilis and congenital syphilis); neglected diseases and communicable diseases related to poverty (leprosy and tuberculosis), also showed profound inequalities. Conclusion: In Colombia there are inequalities by regime of affiliation to the health system. Measured socioeconomic status was a predictor of increased morbidity and premature mortality.

Introducción. Las desigualdades en salud se generan por diferencias en las condiciones sociales y económicas, lo cual influye en el riesgo de enfermar y la forma de enfrentar la enfermedad. Objetivo. Evaluar las desigualdades sociales en salud en Colombia, utilizando el tipo de afiliación al sistema de salud como un parámetro representativo (proxy) de la condición socioeconómica. Materiales y métodos. Se trata de un análisis descriptivo y retrospectivo en el que se calcularon las tasas específicas de incidencia, ajustadas por edad y sexo, para eventos de notificación obligatoria, utilizando el régimen de afiliación (subsidiado o contributivo) como variable representativa del nivel socioeconómico. Las estimaciones se hicieron a nivel departamental para el 2015. Las desigualdades sociales se calcularon en términos de brechas absolutas y relativas. Resultados. Se evidencian desigualdades sociales en la ocurrencia de eventos de notificación obligatoria, las cuales desfavorecen a la población afiliada al régimen subsidiado. En esta población, se reportaron 82,31 casos más de malaria Plasmodium falciparum por 100.000 afiliados, que los notificados en el régimen contributivo. Respecto a la brecha relativa, el pertenecer al régimen subsidiado se asocia con un aumento de 31,74 veces del riesgo de morir por desnutrición en menores de cinco años. Otros eventos también presentaron profundas desigualdades, como los relacionados con la salud sexual y reproductiva (mortalidad materna, sífilis gestacional y sífilis congénita), las enfermedades infecciosas y las enfermedades transmisibles relacionadas con la pobreza (lepra y tuberculosis). Conclusión. El tipo de afiliación al Sistema General de Seguridad Social en Salud en Colombia es un buen indicador del nivel socioeconómico, y es un factor predictor de mayor morbilidad y mortalidad prematura asociada con los factores determinantes sociales de la salud.

Leprosy: prevalence and factors associated with seropositivity for anti-NDO-LID antibodies in children under 15 years of age.

BACKGROUND: A high prevalence of leprosy among children under 15 years of age indicates the need to implement actions to prevent new cases of the disease. Serological tests have been developed with the aim of helping to control the disease by indicating, through seropositivity, the presence of infection. OBJECTIVE: To analyze the prevalence and factors associated with seropositivity rate for anti-NDO-LID antibodies in children under 15 years of age, contacts of leprosy patients. METHOD: We performed a cross-sectional study with 210 children under 15 years old of age. Of them, 50 were household contacts and 160 were neighborhood contacts living in the municipality of Cuiabá, state of Mato Grosso, in 2016. The data were obtained from interviews and the NDO-LID rapid test during home visits from February to July 2016. For the analysis, we used Poisson regression and prevalence ratio. RESULTS: Seropositivity in contacts was 6.2%. Variables associated with seropositive tests included sex (PR = 1.05; 95% CI: 1.01 - 1.08), race/skin color (PR = 0.95; 95% CI: 0.90 - 0.99), residence area (PR = 1.05; 95% CI: 1.01 - 1.09), and number of people per household (PR = 1.06; 95% CI: 1.02 - 1.08). STUDY LIMITATIONS: The small sample size, besides leading to wide confidence intervals, may have been a limitation for the identification of associated factors. CONCLUSIONS: The prevalence of seropositivity was high. Variables associated with NDO-LID seropositivity included female sex, not to be brown skinned, live in urban areas, and live with five or more people.

Validity of maximal oxygen consumption prediction equations in young Saudi females.

OBJECTIVES: To determine the applicability of Jones, Hansen, and Wasserman predictive equations for maximal oxygen consumption (VO2max) in Saudi females.  Methods: This cross-sectional study was conducted at Imam Abdulrahman Bin Faisal University, Dammam, Kingdom of Saudi Arabia, between March and May 2017. Maximal oxygen consumption was measured directly through the COSMED system for cardiopulmonary exercise testing in 102 girls with normal body mass index (19-25 years old). Maximal oxygen consumption was indirectly predicted by Jones, Hansen, and Wasserman equations. Paired t-test, Pearson correlation, and Bland-Altman plot were used for comparison, correlation, and agreement analysis. Results: The difference between the mean and standard deviation (±SD) VO2max values of the direct measurement (27.39±4.06 ml/kg-1/min-1), and the Jones (35.19±2.12 ml/kg-1/min-1), Hansen (33.64±0.24 ml/kg-1/min-1), and Wasserman (35.20±0.17 ml/kg-1/min-1) equations, was statistically significant (p less than 0.001). Bland-Altman plot analysis suggested a lack of agreement between direct and predicted VO2max. Pearson correlation failed to reveal any correlation between direct VO2max and VO2max calculated with any of the 3 equations. Conclusion: Jones, Hansen, and Wasserman equations for prediction of VO2max cannot be justified in the studied population. For the better prediction of VO2max, either these equations should be modified, or a new equation should be developed for the Saudi population.

Predictors of mortality in patients with yellow fever: an observational cohort study.

BACKGROUND: Yellow fever virus infection results in death in around 30% of symptomatic individuals. The aim of this study was to identify predictors of death measured at hospital admission in a cohort of patients admitted to hospital during the 2018 outbreak of yellow fever in the outskirts of São Paulo city, Brazil. METHODS: In this observational cohort study, we enrolled patients with yellow fever virus from two hospitals in São Paolo-the Hospital das Clínicas, University of São Paulo and the Infectious Diseases Institute "Emilio Ribas". Patients older than 18 years admitted to hospital with fever or myalgia, headache, arthralgia, oedema, rash, or conjunctivitis were consecutively screened for inclusion in the present study. Consenting patients were included if they had travelled to geographical areas in which yellow fever virus cases had been previously confirmed. Yellow fever infection was confirmed by real-time PCR in blood collected at admission or tissues at autopsy. We sequenced the complete genomes of yellow fever virus from infected individuals and evaluated demographic, clinical, and laboratory findings at admission and investigated whether any of these measurements correlated with patient outcome (death). FINDINGS: Between Jan 11, 2018, and May 10, 2018, 118 patients with suspected yellow fever were admitted to Hospital das Clínicas, and 113 patients with suspected yellow fever were admitted to Infectious Diseases Institute "Emilio Ribas". 95 patients with suspected yellow fever were included in the study, and 136 patients were excluded. Three (3%) of 95 patients with suspected yellow fever who were included in the study were excluded because they received a different diagnosis, and 16 patients with undetectable yellow fever virus RNA were excluded. Therefore, 76 patients with confirmed yellow fever virus infection, based on detectable yellow fever virus RNA in blood (74 patients) or yellow fever virus confirmed only at the autopsy report (two patients), were included in our analysis. 27 (36%) of 76 patients died during the 60 day period after hospital admission. We generated 14 complete yellow fever virus genomes from the first 15 viral load-detectable samples. The genomes belonged to a single monophyletic clade of the South America I genotype, sub-genotype E. Older age, male sex, higher leukocyte and neutrophil counts, higher alanine aminotransferase, aspartate transaminase (AST), bilirubin, and creatinine, prolonged prothrombin time, and higher yellow fever virus RNA plasma viral load were associated with higher mortality. In a multivariate regression model, older age, elevated neutrophil count, increased AST, and higher viral load remained independently associated with death. All 11 (100%) patients with neutrophil counts of 4000 cells per mL or greater and viral loads of 5·1 log10 copies/mL or greater died (95% CI 72-100), compared with only three (11%) of 27 (95% CI 2-29) among patients with neutrophil counts of less than 4000 cells per mL and viral loads of less than 5·1 log10 copies/mL. INTERPRETATION: We identified clinical and laboratory predictors of mortality at hospital admission that could aid in the care of patients with yellow fever virus. Identification of these prognostic markers in patients could help clinicians prioritise admission to the intensive care unit, as patients often deteriorate rapidly. Moreover, resource allocation could be improved to prioritise key laboratory examinations that might be more useful in determining whether a patient could have a better outcome. Our findings support the important role of the virus in disease pathogenesis, suggesting that an effective antiviral could alter the clinical course for patients with the most severe forms of yellow fever.

Leprosy in children under 15 years of age in Brazil: A systematic review of the literature.

BACKGROUND: Leprosy is a chronic infectious disease neglected, caused by Mycobacterium leprae, considered a public health problem because may cause permanent physical disabilities and deformities, leading to severe limitations. This review presents an overview of the results of epidemiological studies on leprosy occurrence in childhood in Brazil, aiming to alert health planners and managers to the actual need to institute special control strategies. METHODOLOGY/PRINCIPAL FINDINGS: Data collection consisted of an electronic search for publications in eight databases: Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scientific Electronic Library Online (SciELO), PuBMed, Biblioteca Virtual em Saúde (BVS), SciVerse Scopus (Scopus), CAPES theses database, CAPES journals database and Web of Science of papers published up to 2016. After apply selection criteria, twenty-two papers of studies conducted in four different regions of Brazil and published between 2001 and 2016 were included in the review. The leprosy detection rate ranged from 10.9 to 78.4 per 100,000 inhabitants. Despite affecting both sexes, leprosy was more common in boys and in 10-14-year-olds. Although the authors reported a high cure proportion (82-90%), between 1.7% and 5.5% of the individuals developed a disability resulting from the disease. CONCLUSIONS/SIGNIFICANCE: The findings of this review shows that leprosy situation in Brazilian children under 15 years is extremely adverse in that the leprosy detection rate remains high in the majority of studies. The proportion of cases involving disability is also high and reflects the difficulties and the poor effectiveness of actions aimed at controlling the disease. The authors suggest the development of studies in spatial clusters of leprosy, where beyond the routine actions established, are included news strategies of active search and campaigns and actions of educations inside the clusters of this disease. The new agenda needs to involve the precepts of ethical, humane and supportive care, in order to achieve a new level of leprosy control in Brazil.

Demography and the dual epidemics of tuberculosis and HIV: Analysis of cross-sectional data from Sub-Saharan Africa.

BACKGROUND: Convergence of tuberculosis (TB) and HIV epidemics is associated with higher morbidity and mortality risks and understanding their distribution across key demographic factors is essential for prevention and control. This analysis examines the prevalence of TB, HIV and TB-HIV coinfection across age and gender in patients with presumptive TB seeking care at the National TB and Leprosy Training Center in Nigeria. METHODS: Samples from 1603 presumptive pulmonary TB cases who provided informed consent were evaluated with a sequential testing algorithm that included a smear microscopy, cultures in liquid and broth media and then genotyping by Hain line probe assays. HIV was serially tested with two HIV rapid assays and retested with a third assay in non-conclusive samples. RESULTS: Twenty-three percent (375/1603) had confirmed pulmonary TB infection, 23.6% (378/1603) were positive for HIV infection and 26.9% (101/375) of the confirmed TB cases were HIV co-infected. Males had a higher prevalence of TB: 27.6% vs. 18.0%, p < .0001; and a lower prevalence of HIV: 19.0% vs. 29.6%, p < .0001. In the age range of 25-29 years, males were twice as likely to have TB (OR = 2.2; 95% confidence interval [CI]: 1.3-3.9, p = 0.0032) while females were five times more likely to have HIV (OR = 4.8; 95% CI: 2.6-8.9, p < .0001). Persons with TB-HIV coinfection were more likely to be young, female and less likely to be married. CONCLUSION: Younger females with a high burden of HIV may be under-diagnosed and under-reported for TB in Nigeria. Community programs for intensified and early detection of TB and HIV targeting younger females are needed in this setting.

Leprosy in individuals under the age of fifteen in priority cities, Mato Grosso, Brazil. / Hanseníase em menores de quinze anos em municípios prioritários, Mato Grosso, Brasil.

OBJECTIVES: We aimed to compare the sociodemographic, clinical and epidemiological characteristics of individuals under the age of 15, reported to have leprosy, and who lived in priority and non-priority cities, as well as to compare the spatial distribution of these reported cases in such cities. This is a cross-sectional study of new leprosy cases in individuals under the age of 15 (n=429) registered in the Information System for Notifiable Diseases from the State of Mato Grosso, Brazil, between 2011 and 2013. The diagnosed cases were compared regarding sociodemographic, clinical and epidemiological aspects using the chi-square test at a 5% significance level. The spatial distribution was made through ArcGIS 10.2 software. RESULTS: Of the 141 assessed cities in the state, according to the spatial distribution, 58.1% (n=82) showed a high, very high and hyper-endemic mean incidence coefficient, and, of these, 34.1% (n=28) include the group of priority municipalities. Of the new cases included in the study, 73.9% (n=317) were reported in priority cities. We observed a difference in the proportion of cases registered among the cities, with a greater proportion in priority cities, in the age group from five to nine years old (χ²=4.09; p=0.043), in the white race (χ²=7.01; p=0.008) and in the tuberculoid clinical form (χ²=3.89; p=0.048). There was a greater proportion in non-priority cases with regard to non-urban areas (χ²=24.23; p<0.001), two to five skin lesions (χ²=5.93; p=0.014) and spontaneous demand (χ²=6.16; p=0.013). CONCLUSION: The differences highlighted regarding clinical and epidemiological characteristics between the cities demonstrate the difficulty of endemic control in both municipality groups.

OBJETIVOS: Comparar as características sociodemográficas, clínicas e epidemiológicas de indivíduos menores de 15 anos notificados com hanseníase entre os municípios prioritários e os não prioritários, bem como a distribuição espacial destes casos registrados em tais municípios. Trata-se de um estudo transversal a partir de casos novos de hanseníase em menores de 15 anos (n=429) registrados no Sistema de Informação de Agravos de Notificação do estado de Mato Grosso, entre 2011 e 2013. Os casos diagnosticados foram comparados quanto aos aspectos sociodemográficos, clínicos e epidemiológico por meio do teste do qui-quadrado ao nível de significância de 5%. A distribuição espacial foi feita por meio do software ArcGis 10.2. RESULTADOS: Dos 141 municípios do estado avaliados segundo a distribuição espacial, 58,1% (n=82) apresentaram coeficiente médio de incidência alto, muito alto e hiperendêmico, sendo que, destes, 34,1% (n=28) contemplam o grupo dos prioritários. Dos casos novos incluídos no estudo, 73,9% (n=317) foram notificados em municípios prioritários. Observou-se diferença na proporção de casos registrados entre os municípios, com maior proporção nos prioritários quanto à idade de 5 a 9 anos (χ²=4,09; p=0,043), raça branca (χ²=7,01; p=0,008) e forma clínica tuberculoide (χ²=3,89; p=0,048), e maior proporção nos não prioritários quanto à zona não urbana (χ²=24,23; p<0,001), duas a cinco lesões (χ²=5,93; p=0,014) e demanda espontânea (χ²=6,16; p=0,013). CONCLUSÃO: As diferenças evidenciadas em relação às características clínicas e epidemiológicas entre os municípios demonstram a dificuldade de controle da endemia em ambos os grupos de municípios.

A study on gender differences in newly detected leprosy cases in Sichuan, China, 2000-2015.

BACKGROUND: Many researches on gender differences in leprosy found that female patients were detected with the disease later and had more serious disabilities than male patients. We analyzed the gender differences related to epidemiological characteristics of new leprosy cases detected from 2000 to 2015 in Sichuan Province, China. METHODS: A retrospective study was undertaken to analyze the gender differences with respect to age, delay in disease detection, the main modes of detection, and disability grade. The chi-squared test and t test were applied for the comparison using Epi Info 7.2 with a significance level of a = 0.05. The data were collected from the Leprosy Management Information System in China. RESULTS: A total of 2900 new leprosy cases were detected from 2000 to 2015, of whom 2075 (71.6%) were male and 825 (28.4%) were female with a gender ratio of 2.5. The gender ratio of patients aged 15-30 was significantly lower than that of patients aged 31-45 and 46-60. Male cases were older than female cases when they were detected. The proportion of Grade 2 Disability (G2D) among men (20.6%) was significantly higher than that among women (17.3%). The average period of delay in detection among male cases was similar with that among females cases. CONCLUSIONS: Gender-related differences existed among the leprosy cases detected from 2000 to 2015. Female patients were younger than male patients. The detection of leprosy in women was not later than in the case of men. The disability situation in men was more serious than in women.

Serious Adverse Drug Events Reported to the FDA: Analysis of the FDA Adverse Event Reporting System 2006-2014 Database.

BACKGROUND: Data on adverse drug events (ADEs) observed at the population level provide important evidence regarding the safety of a pharmaceutical product in real-world settings. Recent patterns in serious and fatal ADE reporting have not been documented. OBJECTIVE: To assess recent patterns in serious and fatal ADE reports in the United States. METHODS: We conducted a retrospective analysis of the publicly available 2006-2014 FDA Adverse Event Reporting System database. Non-U.S. reports, reports from clinical trials, and reports with missing outcome data were excluded. The annual numbers of ADEs with reported outcome of death, disability, and other serious outcomes were determined. Types (direct, manufacturer expedited, or manufacturer periodic) and sources (consumer, health professional, or other) of these serious ADE reports were also identified. The distribution of serious ADE reports by patient age groups (< 18, 18-44, 45-64, and ≥ 65 years) was determined. Drugs listed as primary suspects in serious ADEs (death, disability, and other serious outcomes) were identified and ranked. Descriptive statistics were used to characterize the patterns in serious or fatal ADE reporting. RESULTS: From 2006 to 2014, the number of serious ADEs reported to the FDA increased 2-fold. A total of 902,323 serious outcomes were reported over the 9-year study period: 244,408 deaths, 72,141 disabilities, and 585,774 other serious outcomes. The relative percentage of reports of deaths was highest during 2012 (32.4%). The percentage of reports of disability was highest during 2006 (12.1%). Overall, the "other serious outcomes" category accounted for almost 65% of serious ADEs reports. Expedited reports from drug manufacturers were most common (about 72%) of the serious ADEs with available data on report type. Health professionals (47.3%) were the most common source of report followed by consumers (36.1%) and other sources (16.6%). A disproportionately high number of reported ADEs was among patients aged 45-64 years (40%) and ≥ 65 years (32.6%). Antineoplastic drugs were more frequently reported with deaths. Three antidepressant drugs were among the top 10 drugs reported with disability. During 2006-2014, there were 38 drugs with more than 1,000 reports of serious ADEs in a given year: 2 drugs currently withdrawn from the market (rofecoxib and parecoxib), 10 drugs with an FDA risk evaluation and mitigation strategies (REMS) program, 13 biologic or specialty drugs, and 14 others. CONCLUSIONS: An overall increase in the trend of the number of serious ADE reports was observed from 2006 to 2014. Drugs with a REMS program and biologic and specialty drugs were involved in a significant number of reported serious ADEs. Data on reporting patterns can guide surveillance and pharmacoepidemiological studies to understand the public health burden of serious ADEs. DISCLOSURES: No outside funding supported this study.
