Morbimortality and determinants of reperfusion in ischemic stroke

SUMMARY BACKGROUND: Cerebrovascular accident (or stroke) and ischemic heart disease are the the major causes of death in the world. It is estimated that about 85% of strokes are ischemic in origin. Reperfusion therapy in the acute phase of ischemic stroke with a recombinant human tissue plasminogen activator is effective, but some factors influence the success of this treatment. OBJECTIVE: The aim of this study was to evaluate clinical aspects and possible determinants for reperfusion after venous thrombolysis. METHODS: This is a retrospective, cross-sectional, observational study based on a review of hospital records of inpatients diagnosed with ischemic stroke treated with intravenous thrombolysis, the main outcome being reperfusion or not. RESULTS: Data from this study revealed a predominance of females in the group of reperfused patients and males in the non-reperfused group, both maintaining moderate severity on the National Institutes of Health Stroke Scale and admission without statistical significance (p>0.18). In addition, the mean admission severity score was 13.2 for the group of reperfused patients and 14.2 for those not reperfused, and the mean ejection fraction of both groups was within normal functionality, with a mean of 0.50 for reperfused patients and 0.62 for non-reperfused patients. CONCLUSION: We found an association between successful venous chemical thrombolysis reperfusion and lower mortality in patients with acute stroke.

Weight gain in patients starting Dolutegravir-based ART according to baseline CD4 count after 48 weeks of follow up

ABSTRACT Background: Excessive weight gain is a current concern among People Living with HIV (PLHIV) starting ART. Objectives: To evaluate the weight gain after 48-weeks of ART in naive patients, according with baseline CD4 count. Methods: PLHIV starting 3TC + TDF + DTG with at least 48-weeks of follow up in two AIDS referral centers were stratified by baseline CD4 count (lower or higher than 200 cells/mm3). Data on CD4 count, HIV viral load, weight/Body Mass Index (BMI), lipids and glucose levels were collected at baseline, 24 and 48 weeks of treatment. For analysis purpose, patients were categorized according to their BMI progression. Results: A total of 270 patients were included in the study. Mean CD4 count were 78.3 ± 61.7 and 536.7 ± 273 cells/mm3 for low and high CD4 count groups, respectively (p < 0.001). Baseline BMI was significantly lower in low CD4 group (21.7 vs. 23.6 Kg/m2, p < 0.001). Patients in low CD4 group gained more weight than those in high CD4 group (11.2 ± 8.5 kg vs. 2.2 ± 4.2 Kg, p = 0.004). Overall weight gain was higher in women, regardless group (13.1 ± 7.9 Kg vs. 1.4 ± 3.6 Kg for women and men, respectively, p < 0.001). The proportion of overweight/obesity significantly increased in low CD4 group. Viral suppression rate was high for both groups. At week 48 the overall proportion of overweight/obesity was like that reported for the Brazilian population. Conclusions: Weight gain in the present study indicates a "return to health" phenomenon. Excessive weight gain was more frequent in women.

Association between personality factors and health-related quality of life in type 1 diabetes patients

ABSTRACT Objectives: The objective of the present study was to evaluate a possible association between personality factors (PF) and the health-related quality of life (HRQoL) of type 1 diabetes (T1D) patients. This allows for the investigation of obstacles related to treatment type and the presence of complications in HRQoL. Materials and methods: This cross-sectional study enrolled 78 patients aged 13-67 years from two diabetes clinics. PF was evaluated using the validated questionnaire Inventory of the Five Great Personality Factors. HRQoL was determined using the Brazilian Problem Areas in Diabetes Scale (B-PAID) questionnaire. The chi-square test, Fisher's exact test, and Welch's modified two-sample t-test were used to establish relationships. Results: In this sample of 46 women and 32 men with T1D and mean A1C of 8%-9%, we observed great suffering in 58.97% and that HRQoL was worse in women. "Openness" was the most prevalent PF and "extroversion" the least prevalent. "Neuroticism" facilitated a tendency to tolerate suffering. Conclusion: T1D patients' personalities influence their treatment. The PF "neuroticism" is potentially related to better HRQoL. Brazilian T1D patients indicated great suffering in their HRQoL, which may be characteristic across the country. Women experienced worse HRQoL, which is in line with world literature. However, the limited sample size in this study warrant further research to test the hypotheses.

Musculoskeletal pain, multimorbidity and associated factors in individuals followed at a physiotherapy service: cross-sectional observational study / Dor musculoesquelética, multimorbidade e fatores associados em indivíduos acompanhados por serviço de fisioterapia: estudo observacional de corte transversal

ABSTRACT BACKGROUND AND OBJECTIVES: Musculoskeletal pain is among the most disabling conditions, aggravating multimorbidity scenarios. Difficulties in the treatment of pain and multimorbidity highlight the importance of the study of these populations. The objective of this study was to determine the frequency of musculoskeletal pain and multimorbidity, the main complaints in patients admitted to physiotherapy services. METHODS: This is a cross-sectional observational study. Patients 50 years or older were evaluated using the Brief Pain Inventory, Roland Morris Disability Questionnaire for general pain, sociodemographic and clinical data form, and timed-up-and-go test. Descriptive analyses were performed through the distribution of absolute numbers and proportions for categorical variables. RESULTS: The sample consisted of 62 patients with 2 or more painful regions, 88.7% women with a median age of 67 years [IQR 62-72], 81% with body mass index above normal, 71% hypertensive and 97% with multimorbidity. The median of painful regions was 7 [IQR 4-8], the most prevalent being low back and knees (87%); 66% of patients describe severe pain, and median pain duration of 7.5 years [IQR 3-15]. The high number of painful regions had greater interference (p<0.05) in the lives of individuals and was associated with females (p=0.04) and the occurrence of a fall in the last year (p<0.003). CONCLUSION: The described population is mostly composed of hypertensive, overweight women with multimorbidity, chronic pain and a high number of painful regions, interfering in activities and in the affective components of life. A continuous study of chronic, diffuse musculoskeletal pain and multimorbidity is necessary, seeking better interventions for these patients.

Anxiety, health-related quality of life, and symptoms of burnout in frontline physicians during the COVID-19 pandemic

ABSTRACT Background: COVID-19 pandemic caused increased workload and stress for health professionals involved in the care of such patients. We aimed to describe the health-related quality of life, and burnout in frontline physicians diagnosed with anxiety during the COVID-19 pandemic. Methods: This was a cross-sectional study conducted during the first-wave phase of COVID19, from September to October 2020. Questionnaires were sent electronically to 450 physicians from State of Bahia, assessing symptoms of anxiety, health-related quality of life (HRQOL) and burnout syndrome. For the categorical variables, the Pearson's chi-square test was used and difference between means was compare using the Mann-Whitney test. was Groups with and without anxiety symptoms were compared using prevalence ratios (PR). Pearson's correlation measured the correlation between WHOQOL-BREF and MBI (Maslach Burnout Inventory) domains. The Fisher r-to-z transformation was used to assess the significance of the difference between two correlation coefficients. The significance level was <0.05. Results: Out of the 450 physicians, 223 (49,6%) completely answered the questionnaire and 38 (17%) showed symptoms of anxiety. Physicians with anxiety had higher scores in emotional exhaustion (EE) (38.31 ± 8.59 vs 25.31±0.87; p = 0.0001) and depersonalization (DP) (9.0 ± 5.6 vs 5.9 ± 5.3; p = 0.001) domains, and lower scores in personal accomplishment (PA) (32.1 ± 8.2 vs 36.3 ± 7.6; p = 0.004), than those without anxiety. All correlations between WHOQOL-BREF domains and MBI in physicians without anxiety were significant (p = 0.01). Conclusion: Physicians with anxiety showed more emotional exhaustion, less personal accomplishment, and lower quality of life. All domains of WHOQOL BREF were correlated with all MBI domains among physicians without anxiety. Differences in correlation according to anxiety were remarkable in psychological HOQOL BREF domain and emotional exhaustion and depersonalization MBI domains. The effect of anxiety leading to poorer levels of perceived health needs to be further investigated.

Self-prescribed Ivermectin use is associated with a lower rate of seroconversion in health care workers diagnosed with COVID, in a dose-dependent response

ABSTRACT Background: Over-the-counter use of ivermectin amongst other drugs as SARS-CoV-2 treatment has been increasingly common, despite the lack of evidence on its clinical efficacy. Objective: To evaluate the effect of ivermectin use on production of antibodies against SARS-CoV-2 in health care workers (HCW) diagnosed with COVID-19 and of Th1/Th2 cytokines by stimulated peripheral blood mononuclear cells of the same cohort (PBMCs). Methods: This cross-sectional study evaluated seroconversion and neutralizing antibodies production in HCW at Complexo Hospitalar Universitário Professor Edgard Santos (Salvador, Brazil), diagnosed with COVID-19 from May to July, 2020, as well as in vitro production of antibody against SARS-CoV-2 and Th1/Th2 cytokines. Analyses were performed between December 2020 and February 2021. Participants were stratified according to the use of ivermectin (≤ 1 dose vs. multiple doses) for treatment of COVID-19. Results: 45 HCW were included (62% women). Mean age was 39 years, and disease severity was similar across groups. Neutralizing antibodies were detected less frequently in multiple doses (70%) vs. ≤ 1 dose (97%) groups, p = 0.02). PBMCs of patients in multiple doses group also were less likely to produce antibodies against SARS-CoV-2 following in vitro stimulation with purified spike protein in comparison with patients in ≤ 1 dose group (p < 0.001). PBMC's production of Th1/Th2 cytokines levels was similar across groups. Abdominal pain (15% vs 46%, p = 0.04), diarrhea (21% vs. 55%, p = 0.05) and taste perversion (0% vs. 18%, p = 0.05) were more frequently reported by participants that used multiple doses of ivermectin. Conclusions: Although there was no evidence for differential disease severity upon ivermectin use for treatment of COVID-19 it was associated with more gastro-intestinal side-effects and impairment of anti-SARS-CoV2 antibodies production, in a dose dependent manner. This potentially impacts the effectiveness of immune response and the risk of reinfection and warrants additional studies for clarifying the mechanisms and consequences of such immunomodulatory effects.

Validation of the GeneXpert Xpress SARS-CoV-2 PCR assay using saliva as biological specimen

ABSTRACT In the pandemic, rapid and accurate detection of SARS-CoV-2 is crucial in controlling the outbreak. Recent studies have shown a high detection rate using saliva/oral fluids as specimens for laboratory detection of the virus. We intended to evaluate the test performance of the Xpert Xpress SARS-CoV-2 cartridge assay in comparison to a conventional qRT-PCR testing, using saliva as biological specimen. Forty saliva samples from symptomatic participants were collected. Conventional qRT-PCR was performed for amplification of E and RdRp genes and the Xpert Xpress SARS-CoV-2 assay amplified E and N2 genes. In the conventional assay, the median cycle threshold value of the E gene was 34.9, and of the RdRp gene was 38.3. In the Xpert Xpress assay, the median cycle threshold value of the E gene was 29.7, and of the N2 gene was 31.6. These results can allow a broaden use of molecular tests for management of COVID-19 pandemic, especially in resources-limited settings.

Spirometry results after treatment for pulmonary tuberculosis: comparison between patients with and without previous lung disease: a multicenter study / Comparação entre os resultados de espirometria após tratamento para tuberculose pulmonar em pacientes com e sem doença pulmonar prévia: um estudo multicêntrico

ABSTRACT Objective: To compare patients with and without previous lung disease, in terms of the spirometry results after they had been treated for pulmonary tuberculosis (PTB) and cured, as well as to analyze risk factors related to functional severity. Methods: This was a cross-sectional, multicenter study conducted at four referral centers in Brazil. Patients were divided into two groups: those with a history of lung disease or smoking (LDS+ group); and those with no such history (LDS− group). Patients underwent spirometry (at least six months after being cured). Sociodemographic and clinical data were collected. Results: A total of 378 patients were included: 174 (46.1%) in the LDS+ group and 204 (53.9%) in the LDS− group. In the sample as a whole, 238 patients (62.7%) had spirometric changes. In the LDS+ group, there was a predominance of obstructive lung disease (in 33.3%), whereas restrictive lung disease predominated in the LDS− group (in 24.7%). Radiological changes were less common in the LDS− group than in the LDS+ group (p < 0.01), as were functional changes (p < 0.05). However, of the 140 (79.1%) LDS− group patients with a normal or minimally altered chest X-ray, 76 (54%) had functional changes (p < 0.01). The risk factors associated with functional severity in the LDS− group were degree of dyspnea (p = 0.03) and moderate or severe radiological changes (p = 0.01). Conclusions: Impaired pulmonary function is common after treatment for PTB, regardless of the history of lung disease or smoking. Spirometry should be suggested for patients who develop moderate/severe dyspnea or relevant radiological changes after treatment for PTB.

RESUMO Objetivo: Comparar os resultados da espirometria de pacientes tratados e curados para tuberculose pulmonar (TBP) com e sem doença pulmonar prévia e analisar os fatores de risco relacionados à gravidade funcional. Métodos: Estudo transversal, multicêntrico, em quatro centros de referência no Brasil. Os pacientes foram classificados em dois grupos: grupo com doença pulmonar prévia ou história de tabagismo (grupo DPT+) e grupo sem doença pulmonar prévia e sem tabagismo (grupo DPT−). Os pacientes realizaram espirometria (pelo menos seis meses após a cura), e foram coletados dados sociodemográficos e clínicos. Resultados: Foram incluídos 378 pacientes: 174 (46,1%) no grupo DPT+ e 204 (53,9%) no grupo DPT−. Na amostra total, 238 pacientes (62,7%) apresentaram alguma alteração espirométrica. No grupo DPT+ houve predominância de distúrbio ventilatório obstrutivo (em 33,3%), e distúrbio ventilatório restritivo predominou no grupo DPT− (em 24,7%). Quando comparados com o grupo DPT+, os pacientes do grupo DPT− apresentaram menos frequentemente alteração radiológica (p < 0,01) e funcional (p < 0,05). Porém, dos 140 (79,1%) do grupo DPT− com radiografia de tórax normal ou minimamente alterada, 76 (54%) apresentaram alguma alteração funcional (p < 0,01). Os fatores de risco relacionados com a gravidade funcional no grupo DPT− foram grau de dispneia (p = 0,03) e alterações radiológicas moderadas ou acentuadas. Conclusões: O comprometimento da função pulmonar é frequente após o tratamento da TBP independentemente do histórico de tabagismo ou doença pulmonar prévia. A espirometria deve ser sugerida para esses pacientes que evoluem com grau moderado/grave de dispneia e/ou alteração radiológica relevante após o tratamento da TBP.

Factors associated with mortality in HIV patients failing antiretroviral therapy, in Salvador, Brazil

ABSTRACT Highly active antiretroviral therapy (HAART) has significantly improved survival of people living with HIV/Aids (PLWHA). However, poor treatment adherence to HAART and other problems, still cause therapy failure and contribute to increased morbidity and mortality of PLWHA. In this retrospective cohort study (2013-2015), we sought to evaluate the factors associated with mortality of PLWHA failing HAART in 2013, who were receiving care at a reference center for sexually transmitted diseases (STD) and HIV/AIDS. A total of 165 individuals over 18 years of age who were failing antiretroviral therapy were evaluated. In two-year follow-up, 19 (11.5%) deaths were documented. There were a significant association between mortality and report of illicit drug use (53%, p < 0.01), being attended by a larger number of medical professionals (6.3 ± 3.2, p = 0.02), use of firstline non-nucleoside reverse transcriptase inhibitor (74%, p = 0.01), and history of interrupting HAART ≥3 months (90%), p = 0.02). Patients who died had a significantly higher viral load (mean 49,192.4 ± 35,783.6 copies/mL) than survivors (26,389.2 ± 27,416 copies/mm3, p < 0.01), lower mean CD4 cell counts (127.8 ± 145.6 cells/mm3 vs. 303.3 ± 202.4 cells/mm3, p < 0.01), and higher frequency of previous virologic failure (89% vs. 74.7%, p < 0.01). Our results reinforce the importance of early detection and prevention of virologic failure, to reduce the mortality associated with this event.

Smoking and pulmonary tuberculosis treatment failure: a case-control study / Tabaquismo y fracaso del tratamiento de la tuberculosis pulmonar. Un estudio de casos y controles

ABSTRACT Objective: To determine the association between smoking and pulmonary tuberculosis treatment failure. Methods: This was a case-control study conducted at the Brazilian Institute for Tuberculosis Research in the city of Salvador, Brazil, between 2007 and 2015. We evaluated 284 patients treated for pulmonary tuberculosis, comparing 50 cases of treatment failure with 234 control cases in which the final outcome was cure. Results: Treatment failure was attributed to smoking and age rather than to gender, income, level of education, alcohol consumption, or marital status. Therefore, even after adjustment for age, the risk of treatment failure was 2.1 times (95% CI: 1.1-4.1) higher among the patients with a history of smoking. In addition, being over 50 years of age was found to increase the likelihood of treatment failure by 2.8 times (95% CI: 1.4-6.0). Conclusions: Smoking and aging are both associated with pulmonary tuberculosis treatment failure. Therefore, as part of a tuberculosis control program, health personnel should be prepared to offer strategies to promote smoking cessation and should be more careful with older patients.

RESUMEN Objetivo: Determinar la asociación entre el tabaquismo y el fracaso del tratamiento de la tuberculosis pulmonar. Metodología: Este es un estudio caso - control, realizado en el Instituto Brasilero para la Investigación de la Tuberculosis en Salvador, Brasil entre 2007 y 2015. Se compararon 50 casos de fracaso en el tratamiento con 234 controles de pacientes con diagnóstico de tuberculosis pulmonar y con resultado final de cura. Resultados: Se atribuyó el fracaso del tratamiento al tabaquismo y a la edad, y no al sexo, salario, escolaridad, consumo de alcohol o estado civil. Así, aun después del ajuste por edad, los pacientes con antecedentes de tabaquismo tienen 2,1 (IC95% 1,1-4,1) veces más chance de fracaso en el tratamiento de la tuberculosis. Además, tener una edad mayor de 50 años mostró que la posibilidad de fracaso aumenta 2,8 (IC95% 1,4-6,0) veces más. Conclusiones: El tabaquismo está relacionado con el fracaso del tratamiento de la tuberculosis pulmonar, así como también el envejecimiento. Por tal motivo, como parte del control de la tuberculosis, el personal de salud debe estar preparado para ofrecer estrategias que promuevan la cesación tabáquica y tener un mayor cuidado con pacientes de grupos etarios superiores.

Expansão da circulação do vírus Zika da África à América, 1947-2018: revisão da literatura / Expansión de la circulación del virus Zika de África a América, 1947-2018: una revisión de literatura / Expansion of Zika virus circulation from Africa to the Americas, 1947-2018: a literature review

Objetivo: descrever as expansões temporal e geográfica da circulação do vírus Zika (ZIKV) em países e territórios, desde seu isolamento até 2018. Métodos: revisão não sistemática da literatura do período entre 1947 e 2018, utilizando a base MEDLINE e estimativas da Organização Mundial da Saúde. Resultados: desde seu isolamento em 1947, a circulação do ZIKV expandiu-se pela África, Ásia e Pacífico, até chegar à América em 2013, causando manifestações clínicas graves; as maiores soroprevalências foram registradas na ilha de Yap (74%) e no Brasil (63%); mutações genéticas, a ausência de imunidade e a alta susceptibilidade dos vetores podem ter influenciado sua transmissibilidade e ajudam a explicar a magnitude de sua expansão. Conclusão: a expansão da circulação do ZIKV nas Américas foi a mais ampla já registrada, possivelmente resultado de características populacionais e geográficas dos locais por onde o vírus circulou.

Objetivo: Describir las expansiones temporal y geográfica de la circulación del virus Zika en países y territorios, desde su aislamiento hasta 2018. Métodos: Revisión no sistemática de la literatura del período comprendido entre 1947 y 2018 utilizando la base MEDLINE y estimaciones de la Organización Mundial de la Salud. Resultados: Desde su aislamiento en 1947 la circulación del virus Zika se expandió por África, Asia y el Pacífico hasta llegar a América en 2013, causando manifestaciones clínicas graves. Las mayores seroprevalencias se registraron en la isla Yap (74%) y en Brasil (63%). Mutaciones genéticas, ausencia de inmunidad y alta susceptibilidad de los vectores pueden haber influenciado su transmisibilidad y ayudan a explicar la magnitud de su expansión. Conclusión: La expansión de la circulación del virus Zika en las Américas fue la más amplia ya registrada, posiblemente como resultado de características poblacionales y geográficas de los lugares por donde el virus circuló.

Objective: to describe the temporal and geographical expansion of Zika virus (ZIKV) circulation in countries and territories, from the time it was first isolated until 2018. Methods: This was a non-systematic literature review covering the period from 1947 to 2018 using the MEDLINE database and World Health Organization estimates. Results: Since its isolation in 1947, ZIKV circulation spread through Africa, Asia and the Pacific before reaching the Americas in 2013, causing serious clinical manifestations; the highest seroprevalence rates were recorded in Yap (74%) and in Brazil (63%); genetic mutations, absence of immunity and high vector susceptibility may have influenced ZIKV transmissibility and help to explain the magnitude of its expansion. Conclusion: The spread of ZIKV circulation in the Americas was the most extensive recorded thus far, possibly as a result of population and geographical characteristics of the sites where the virus circulated.

Management of COPD within the Brazilian Unified Health Care System in the state of Bahia: an analysis of real-life medication use patterns / Gerenciamento da DPOC no Sistema Único de Saúde do estado da Bahia: uma análise do padrão de utilização de medicamentos na vida real

ABSTRACT Objective: To describe COPD pharmacological treatment patterns in the state of Bahia, Brazil, and to evaluate the extent to which these patterns conform to clinical guidelines for the management of COPD. Methods: This was a cross-sectional study of 441 patients referred from the Public Health Care Network of the state of Bahia to a public referral outpatient clinic of a COPD management program of the Brazilian Unified Health Care System. Individuals with a spirometry-confirmed diagnosis of moderate to very severe COPD were included in the study. Patients were evaluated as to whether they had used any COPD medications in the last seven days. The appropriateness or inappropriateness (undertreatment or overtreatment) of the patient's pharmacological treatment was evaluated by comparing the patient's current treatment with that recommended by national and international guidelines. Results: A total of 383 individuals were included in the analysis. Approximately half of the patients (49.1%) used long-acting bronchodilators. These patients were older and had had the disease longer. Of the sample as a whole, 63.7% and 83.0% did not receive pharmacological treatment in accordance with international and national recommendations, respectively. Inappropriateness due to undertreatment was indentified in more than half of the patients. Conclusions: Long-acting bronchodilators are frequently underused in individuals with moderate to very severe COPD within the Brazilian Unified Health Care System in the state of Bahia. Most patients in our sample were treated inappropriately, and undertreatment predominated. Strategies to improve access to long-acting bronchodilators and the quality of COPD pharmacological management are required.

RESUMO Objetivo: Descrever o padrão de tratamento farmacológico da DPOC no estado da Bahia e avaliar a conformidade desse padrão com diretrizes clínicas de manejo da doença. Métodos: Estudo de corte transversal envolvendo 441 pacientes referenciados da Rede de Atenção à Saúde do Estado da Bahia para um ambulatório de referência público de um programa do Sistema Único de Saúde de gerenciamento da DPOC. Foram incluídos no estudo indivíduos com diagnóstico de DPOC moderada a muito grave, confirmado por espirometria. Os pacientes foram avaliados com relação ao uso de algum medicamento para o tratamento da doença nos últimos sete dias. A avaliação da adequação ou da inadequação (sub ou sobretratamento) do tratamento farmacológico dos pacientes foi realizada comparando-se o tratamento atual desses pacientes ao preconizado por diretrizes nacionais e internacionais. Resultados: Um total de 383 indivíduos foi incluído na análise. Aproximadamente metade dos pacientes (49,1%) utilizava algum broncodilatador de longa duração. Esses pacientes eram mais idosos e possuíam maior tempo de duração da doença. Da amostra, 63,7% e 83,0% não recebiam tratamento farmacológico em concordância com as recomendações internacionais e nacionais, respectivamente. A inadequação por subtratamento foi identificada em mais da metade dos pacientes. Conclusões: Os broncodilatadores de longa duração são frequentemente subutilizados em indivíduos com DPOC moderada a muito grave no Sistema Único de Saúde da Bahia. Nesta amostra, a maioria dos pacientes era tratada de forma inadequada, com predominância de subtratamento. Estratégias que melhorem o acesso a broncodilatadores de longa duração e a qualidade do manejo farmacológico da doença são necessárias.

Low variation in initial CD4 cell count in a HIV referral center, in Salvador, Brazil, from 2002 to 2015

ABSTRACT Early initiation of antiretroviral therapy increases the likelihood of effective immune restoration, quality of life, and greater life expectancy for HIV-infected individuals. We evaluated the evolution of mean CD4+ cells count at diagnosis of HIV/AIDS in Salvador, Brazil from 2002 to 2015. We identified HIV/AIDS patients older than 18 years with diagnosis of HIV infection from 2002 to 2015, who had their first laboratory evaluation at Complexo Hospitalar Prof. Edgard Santos, Federal University of Bahia. Initial mean CD4+ cells count and age, over time were evaluated. A total of 1801 patients randomly selected individuals were included in the analysis. Overall mean CD4+ count at diagnosis in the whole period was 279 ± 265, varying from 191 in 2015 to 334 in 2011. There was no improvement in the immunological status at diagnosis from 2002 to 2015. In addition, a higher frequency of CD4+ cells count < 200 cells/mL in the last two years was observed. This suggests that the adopted strategies for early diagnosis of HIV/AIDS in Salvador, Brazil, are still ineffective.

Tuberculosis incidence among people living with HIV/AIDS with virological failure of antiretroviral therapy in Salvador, Bahia, Brazil

Abstract Antiretroviral therapy for HIV has led to increased survival of HIV-infected patients. However, tuberculosis remains the leading opportunistic infection and cause of death among people living with HIV/AIDS. Tuberculosis has been shown to be a good predictor of virological failure in this group. This study aimed to evaluate the incidence of tuberculosis and its consequences among individuals diagnosed with virological failure of HIV. This was a retrospective cohort study involving people living with HIV/AIDS being followed-up in an AIDS reference center in Salvador, Bahia, Brazil. Individuals older than 18 years with HIV infection on antiretroviral therapy for at least six months, diagnosed with virological failure (HIV-RNA greater than or equal to 1000 copies/mL), from January to December 2013 were included. Tuberculosis was diagnosed according to the criteria of the Brazilian Society of Pneumology. Fourteen out of 165 (8.5%) patients developed tuberculosis within two years of follow-up (incidence density = 4.1 patient-years). Death was directly related to tuberculosis in 6/14 (42.9%). A high incidence and tuberculosis-related mortality was observed among patients with virological failure. Diagnosis of and prophylaxis for tuberculosis in high-incidence countries such as Brazil is critical to decrease morbidity and mortality in people living with HIV/AIDS.

Virological suppression in children and adolescents is not influenced by genotyping, but depends on optimal adherence to antiretroviral therapy

ABSTRACT Objective: To evaluate the virological outcomes in children and adolescents infected with HIV-1 in Salvador, Bahia according to genotyping results. Methods: We retrospectively evaluated the rates of virological suppression of children and adolescents submitted to HIV-1 genotyping test from January/2008 to December/2012. The participants were followed in the two referral centers for pediatric AIDS care, in Salvador, Brazil. Resistance mutations, drug sensitivity profiles, and viral subtypes were analyzed using the Stanford HIV-1 Drug Resistance Database. Adherence was estimated by drugs withdrawal at pharmacies of the two sites. Results: 101 subjects were included: 35 (34.6%) were drug-naïve, and the remaining 66 were failing ART. In drug-naïve group, 3 (8.6%), presented with NNRTIs resistance mutations, along with polymorphic mutations to PIs in most (82.8%) of them. Among the failing therapy group, we detected a high frequency (89.4%) of resistance mutations to PIs, NRTI (84.8%), and NNRTI (59.1%). Virological suppression after introduction/modification of genotyping-guided ART was achieved only for patients (53.1%) with drug withdrawal over 95%. Main detected HIV-1 subtypes were B (67.3%), F (7.9), C (1.9%), and recombinant forms (22.9%). Conclusions: Despite the use of genotyping tests in guidance of a more effective antiretroviral regimen, poor adherence to ART seems to be the main determinant of low virological suppression rate for children and adolescents, in Salvador, Brazil.

Chronic symptoms and pulmonary dysfunction in post-tuberculosis Brazilian patients

ABSTRACTBACKGROUND: Questionnaire and spirometry were applied to post-tuberculosis indigenous and non-indigenous individuals from Dourados, Brazil, to investigate the prevalence of chronic respiratory symptoms and pulmonary dysfunction.METHODS:This was a cross-sectional study in cured tuberculosis individuals as reported in the National System on Reportable Diseases (SINAN) from 2002 to 2012.RESULTS:One hundred and twenty individuals were included in the study and the prevalence of chronic respiratory symptoms was 45% (95% CI, 34-59%). Respiratory symptoms included cough (28%), sputum (23%), wheezing (22%) and dyspnea (8%). These symptoms were associated with alcoholism, AOR: 3.1 (1.2-8.4); less than 4 years of schooling, AOR: 5.0 (1.4-17.7); and previous pulmonary diseases, AOR: 5.4 (1.7-17.3). Forty-one percent (95% CI, 29-56) had pulmonary disorders, of which the most prevalent were obstructive disorders (49%), followed by obstructive disorder with reduced forced vital capacity disorders (46%) and restrictive disorders (5%). The lifestyle difference could not explain differences in chronic symptoms and/or the prevalence of pulmonary dysfunction.CONCLUSION:The high prevalence of chronic respiratory symptoms and pulmonary dysfunction in post-tuberculosis patients indicates a need for further interventions to reduce social vulnerability of patients successfully treated for tuberculosis.

High degree of concordance between flow cytometry and geno2pheno methods for HIV-1 tropism determination in proviral DNA

Use of CCR5 antagonists requires previous viral tropism determination. The available methods have high cost, are time-consuming, or require highly trained personnel, and sophisticated equipment. We compared a flow cytometry-based tropism assay with geno2pheno method to determine HIV-1 tropism in AIDS patients, in Bahia, Brazil. We tested peripheral blood mononuclear cells of 102 AIDS patients under antiretroviral therapy by using a cytometry-based tropism assay and geno2pheno assay. Cellular membrane receptors were identified by using CXCR4, CCR5 and CD4 monoclonal antibodies, while detection of cytoplasmic mRNAs for gag and pol HIV regions was achieved by using a labeled probe. Genotypic identification of X4 and R5 tropic viruses was attempted by geno2pheno algorithm. There was a high degree of concordance between cytometry-based tropism assay and geno2pheno algorithm in determination of HIV-1 tropism. Cytometry-based tropism assay demonstrated higher sensitivity and specificity in comparison to geno2pheno, which was used as a gold-standard. One sample could not be amplified by geno2pheno method, but was classified as duotropic by cytometry-based tropism assay. We did not find any association between CD4+ count or plasma HIV-1 RNA viral load and tropism results. The overall performances of cytometry-based tropism assay and geno2pheno assay were almost identical in determination of HIV-1 tropism.

Hanseníase: avaliação em contatos intradomiciliares / Leprosy: evaluation in household contacts

INTRODUÇÃO: Os contatos intradomiciliares de hanseníase são meios para a manutenção da endemia. OBJETIVO: Identificar os motivos por que os contatos intradomiciliares não procuraram a Unidade de Saúde da Família (USF) para realização do exame dermatoneurológico, no município de Cajazeiras (PB). MÉTODOS: Pesquisa exploratório-descritiva, com abordagem qualitativa, realizada em três USF do referido município. Os dados foram coletados em entrevista, mediante aplicação de roteiro estruturado, durante visitas domiciliares a 31 contatos de casos de hanseníase; os dados foram tratados por meio da análise de conteúdo de Bardin. RESULTADOS: O principal motivo para a não realização do exame dermatoneurológico foi ausência de sinais e sintomas de hanseníase, e sentimentos como: medo do exame, desconfiança no serviço, dentre outros. CONCLUSÃO: Os contatos intradomiciliares não procuraram a USF para realização do exame dermatoneurológico por falta de informações prestadas pelos profissionais de saúde que os atendem na Estratégia em Saúde da Família.

INTRODUCTION: The household contacts of leprosy are means for the maintenance of the disease. OBJECTIVE: To identify the reasons why household contacts have not sought the Family Health Unit (FHU) for the dermatoneurological exam, in the municipality of Cajazeiras (PB). METHODS: Exploratory descriptive study with a qualitative approach, performed in three FHU of the mentioned municipality. Data were collected through interviews, by applying semi-structured script, during visits to 31 contacts of leprosy cases. The data were treated from Bardin's contentanalysis. RESULTS: The main reason for not performing the dermato-neurological examination was the absence of signs and symptoms of leprosy, and feelings such as fear of examination, distrust of service, among others. CONCLUSION: Household contacts have not sought the Family Health Unit (FHU) for the dermato-neurological exam for lack of information provided by health professionals who serve at the FHS.

Ferramentas no diagnóstico da hanseníase: o convencional e as inovações / Tools in diagnosis of leprosy: the conventional and innovations

A hanseníase é uma doença infecciosa, crônica, causada pelo Mycobacterium leprae, que afeta, em geral, a pele e os nervos periféricos. A neuropatia periférica é sua principal manifestação e responde pelo potencial da doença, em causar incapacidades e deformidades físicas. A hanseníase representa um grave problema de saúde pública, pois em regiões endêmicas a detecção de casos novos permanece relativamente estável. Esta pesquisa teve como objetivo apresentar as ferramentas convencionais e as inovações para o diagnóstico da hanseníase. Trata-se de uma revisão de literatura. Além do diagnóstico clínico, existem outras ferramentas convencionais para elucidação da hanseníase, tais como a baciloscopia, o teste cutâneo e o exame histopatológico. Uma das ferramentas inovadoras no diagnóstico da hanseníase é o teste sorológico, baseado na detecção de anticorpos específicos, quase universalmente positivos em pacientes MB, mas têm uma sensibilidade insuficiente para a definição diagnóstica em pacientes PB. Outra inovação é a técnica da PCR, método que vem revolucionando a prática da Biologia Molecular, usada para amplificar pequenas quantidades de DNA ou RNA. Existe ainda muitos espaços para novos testes diagnósticos que seriam necessários para a distinção entre indivíduos expostos/infectados e os que podem ter uma evolução ativa para a doença, permitindo um diagnóstico precoce e, assim, interrompendo sua cadeia de transmissão.
