Sex- and Age-Related Impact of the COVID-19 Pandemic on Emergency Department Visits for Chest Pain in Curitiba, Brazil.

BACKGROUND: Women have higher mortality from acute coronary syndrome (ACS) compared with men. Women may hesitate to search for emergency care when experiencing chest pain, which delays treatment. OBJECTIVE: Our aim was to evaluate the changes in emergency visits for chest pain according to sex and age during the COVID-19 pandemic period compared with previous years. METHODS: We collected data on chest pain visits (International Classification of Diseases, Tenth Revision, Clinical Modification codes I20 [unstable angina], I21 [myocardial infarction], and R07.1-4 [chest pain]) from all public emergency departments (EDs) in Curitiba, Brazil. We compared the weekly rates of visits per 100,000 habitants on the epidemiologic weeks 11-52 of 2020 (COVID-19 pandemic period) with the average rates of the same weeks of 2018 and 2019 using Poisson regression. RESULTS: From 2018 to 2020, 37,448 individuals presented to the ED for chest pain, of whom 8493 presented during the COVID-19 pandemic period. Compared with previous years, we observed a 23% reduction in chest pain visits (10.1 vs. 13.0 visits per 100,000 habitants/week; p < 0.001), but this reduction was greater in women than in men (30% vs. 15%; p < 0.001). This reduction was associated with age among women (27%, 31%, and 36% for < 50 years, between 50 and 69 years and > 70 years, respectively, p for age-related trend = 0.041), but not among men. CONCLUSIONS: In this population-level study of Curitiba, Brazil, the reduction in ED visits during the COVID-19 pandemic was greater in women than in men, particularly among those > 70 years of age, suggesting that the sex- and age-related disparities in health care delivery for ACS may have worsened during the COVID-19 pandemic.

Noncommunicable diseases and their common risk factors in Curitiba, Brazil: results of a cross-sectional, population-based study.

OBJECTIVE: To describe the estimated prevalence of noncommunicable diseases and their common risk factors among the adult population of Curitiba, Paraná, Brazil, based on results of the EPIdemiology of CURitiba: EvaluAtion of Noncommunicable diseases (EPICUREAN) study. METHODS: This was a cross-sectional, population-based survey of 1 103 residents of Curitiba, grouped by age (18 - 39 years of age, 40 - 59, and ≥ 60 years), conducted in August 2013 - August 2014. Household interviews, anthropometry, blood pressure measurements, and fasting capillary glycemia were performed during two visits to each participant. The analyses included frequency distribution and prevalence estimates of main outcomes. Prevalence estimates, weighted by age and sex, were presented as absolute numbers and percentages. RESULTS: Prevalence estimates for self-reported depression were 21.2%; hypertension, 31.2%; diabetes, 9.1%; self-reported dyslipidemia, 21.7%; obesity, 21.2%; current smoking, 16.1%; binge drinking, 23.4%; and insufficient physical activity, 35.1%. Prevalences of diabetes and hypertension were higher among individuals with less schooling and the elderly. Binge drinking and leisure-time physical activity were more prevalent in young adults. Men presented higher prevalences of overweight, current smoking, and harmful use of alcohol. Obesity and moderate- to-severe risk of depression were more frequent among women and those with lower income. CONCLUSIONS: The prevalence of NCDs and common risk factors among the adult population of Curitiba are high and reveal a gradient of vulnerabilities by age, sex, education level, and income. To address health inequities and meet the needs of different population groups, the health system should monitor NCDs and risk factors and implement equitable public health policies.

Incidence of recent human immunodeficiency virus infection at two voluntary counseling testing centers in Pernambuco, Brazil, from 2006 to 2009.

This study shows HIV-1 incidence in the northeastern region of Brazil, where the HIV epidemic has spread recently. Incidence was higher among men (1.34%; 95% confidence interval [CI], 1.00% to 1.69%) than among women (0.55%; 95% CI, 0.43% to 0.68%) (P < 0.0001), and there was an association between younger age and recent HIV infection (P < 0.004).

Primary resistance of HIV to antiretrovirals among individuals recently diagnosed at voluntary counselling and testing centres in the metropolitan region of Recife, Pernambuco.

Determining the prevalence and type of antiretroviral (ARV) resistance among ARV-naïve individuals is important to assess the potential responses of these individuals to first-line regimens. The prevalence of primary resistance and the occurrence of recent infections among individuals with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) were identified among recently diagnosed patients at five sexually transmitted disease/AIDS testing and counselling centres in the metropolitan region of Recife (RMR), Pernambuco, Brazil, between 2007-2009. One-hundred and eight samples were analysed using the Calypte® BED assay. Males predominated (56%), as did patients aged 31-50 years. Twenty-three percent presented evidence of a recent HIV infection. The median CD4+ T lymphocyte count was 408 cells/mm³ and the median viral load was 3.683 copies/mL. The prevalence of primary resistance was 4.6% (confidence interval 95% = 1-8.2%) based on criteria that excluded common polymorphisms in accordance with the surveillance drug resistance mutation criteria. The prevalence of resistance to non-nucleoside reverse transcriptase, nucleoside/nucleotide reverse transcriptase and protease inhibitors were 3.8%, 1.5% and 0.8%, respectively. Fifty-seven percent of strains were from clade B, 37.7% were clade F and 3.1% were clade C; there were no statistically significant differences with respect to resistance between clades. Recent infection tended to be more common in men (p = 0.06) and in municipalities in the south of the RMR (Jaboatão dos Guararapes and Cabo de Santo Agostinho) (p = 0.046). The high prevalence of recent infection and the high prevalence of non-B strains in this poor Brazilian region merit further attention.

Socioeconomic Status: The Missing Link Between Obesity and Diabetes Mellitus?

BACKGROUND: Currently, there is an epidemic expansion of obesity rates worldwide. The increasing number of obese individuals associated with the aging of population leads to increasing number of individuals with type 2 diabetes mellitus (T2DM) at the same rate. The traditional factors that link obesity to T2DM are related to genetics, hypercaloric diet, sedentary lifestyle, and stress. Individuals from lower Socioeconomic Status (SES) have restricted autonomy and opportunities that could lead to more stress and consequently increase in stress hormones, such as cortisol, catecholamines, glucagon, and growth hormone, which might ultimately change fat deposition, increasing visceral fat and increasing the risk of T2DM development. METHODS: We conducted a review of the literature on the effects of low SES and the risk of developing T2DM in obese persons. RESULTS: 191 studies were found. The obesity of lower SES individuals is more central than that for individuals from higher socioeconomic position. It is also proposed that the quality of food seems to be lower, with more intake of fat and simple carbohydrates and less of fruits, vegetables and whole wheat bread, in the more disadvantaged social classes. The lower income neighborhoods, without exercise facilities and unsafety are also associated with higher indices of physical inactivity. Cross sectional and prospective studies confirm the relationship between lower socioeconomic status and obesity and diabetes. The lower SES is associated to metabolic implications that are linked to insulin resistance and possibly may also interfere with the ability of beta cell to secrete insulin and change the gut microbiota, increasing even more the future risk of developing diabetes.

Neck Circumference and its Correlation to Other Anthropometric Parameters and Finnish Diabetes Risk Score (FINDRISC).

BACKGROUND: The Neck Circumference (NC) is an anthropometric measure to evaluate obesity. The FINDRISC predicts the risk of developing type 2 diabetes mellitus. Our aims were to identify the mean value of NC in individuals with higher (≥15 points) and lower FINDRISC and to establish cutoff values that indicate individuals with higher FINDRISC. METHODS: It is a population-based, cross-sectional study representative of the city of Curitiba, Brazil. We studied individuals (>18 years), without diabetes mellitus, between August 2013 and August 2014. We evaluated anthropometric parameters, glycaemia, socioeconomic situation, chronic conditions, and their risk factors. In a sex-specific analysis, data are presented as mean and standard deviation. We performed Pearson's and Spearman's correlation between NC and the waist circumference, body mass index and FINDRISC. Receiver Operating Characteristic curves were estimated for NC and higher FINDRISC. Logistic regression models were built to analyze the association between higher FINDRISC and 1-SD increase in NC. RESULTS: We studied 950 individuals (621 women) with a mean age of 47.4 ± 17.6 years and body mass index of 26.2 ± 5.6 kg/m2. The mean NCs were 34.1 ± 3.1 cm in women and 38.2 ± 3.5 cm in men. Mean NC was lower in women (33.7 ± 2.9 cm vs. 35.8 ± 3.2 cm) and men (37.7 ± 3.4 cm vs. 41 ± 3.6 cm) with lower FINDRISC (p <0.001). All the correlations with NC were significant (p ≤ 0.001). The area under the curve for NC and the higher FINDRISC was 0.702 (95% CI 0.653 - 0.752) for women and 0.762 for men (95% CI 0.679 - 0.845), determining the best cutoff value of 34.5 cm for women and 39.5 cm for men to discriminate individuals with higher FINDRISC. Fully adjusted odds ratios for higher FINDRISC per 1-SD increase in NC in women and men were, respectively 1.89 (95% CI 1.53 - 2.33) and 2.86 (95% CI 1.91 - 4.29). CONCLUSION: NC is positively correlated to the body mass index, waist circumference, glycaemia, and FINDRISC scores in a population-based sample of adults. We identified the mean values of NC in higher and lower FINDRISC and established cutoff values for NC and higher FINDRISC.

Increase in human immunodeficiency virus 1 diversity and detection of various subtypes and recombinants in north-eastern Brazil.

PURPOSE: Diverse human immunodeficiency virus 1 (HIV-1) subtypes and circulating recombinant forms are found in Brazil. The majority of HIV-1 molecular epidemiological studies in Brazil have been conducted in the southern and south-eastern regions of the country, although several recent studies in the north-eastern region have addressed this issue. The objective of this study was to molecularly characterize HIV-1 circulating in Pernambuco, north-eastern Brazil. METHODOLOGY: A total of 64 samples were collected from 2002 to 2003, and another 103 were collected from 2007 to 2009. The protease and partial reverse transcriptase regions of the HIV-1 polymerase-encoding (pol) gene were sequenced, and subtyping, recombination and phylogenetic analyses were performed.Results/Key findings. Subtype B (60.9 %) was found to be predominant, followed by HIV-1 F (31.4 %). Several BF recombinants (4.2 %), and BC and AG recombinants were also identified. The intra-subtype genetic diversity was estimated to be 0.065 (sd±0.004) for HIV-1 B and 0.055 (sd±0.004) for HIV-1 F, reflecting a greater accumulation of mutations in subtype B (P<0.01). More codons were found to be under positive selective pressure in samples collected from 2007 to 2009, from individuals with a T-cell count≥200 cells mm-3 and from women. Coalescence data indicated that the subtype F population has been continuously expanding. CONCLUSIONS: HIV-1 shows high genetic diversity in the state of Pernambuco. Thus, additional molecular evaluations of circulating strains will provide a better understanding of the epidemic and may lead to more effective preventive strategies.

Safety and antiulcer efficacy studies of Achillea millefolium L. after chronic treatment in Wistar rats.

Achillea millefolium L. (Asteraceae), popularly known as yarrow, has been used in folk medicine to treat complaints such as inflammation, pain, wounds, hemorrhages and gastrointestinal disturbances. The aim of the present study was to assess the safety and efficacy of the aqueous extract (AE) of the plant after chronic exposure. Indeed, the AE was effective in protecting the gastric mucosa against acute gastric lesions induced by ethanol and indomethacin and in healing chronic gastric lesions induced by acetic acid with (ED(50)=32 mg/kg, p.o.). Safety studies were performed in female and male Wistar rats treated daily with AE (0.3-1.2 g/kg, p.o./day) or vehicle (water, 10 ml/kg/day) for 28 or 90 consecutive days. Satellite groups consisted of animals sacrificed 30 days after the end of these treatments. Clinical observations, body and organ weight measurements, gross autopsy, hematology, clinical biochemical and histopathological examinations were performed. Slight changes in liver weight, cholesterol, HDL-cholesterol and glucose were observed in male and female animals. These changes were not correlated with dose or time of exposure of the animals to the AE. Overall, the results show the antiulcer potential of the aerial parts of the Achillea millefolium which is accompanied by no signs of relevant toxicity even at very long chronic exposure.

Epidemiological, Clinical and Antiretroviral Susceptibility Characterization of Human Immunodeficiency Virus Subtypes B and Non-B in Pernambuco, Northeast Brazil.

BACKGROUND: HIV-1 diversity causes important differences in the virus' biological properties and their interactions with hosts, such as cell tropism, responses to antiretroviral therapy, drug-resistance, and disease progression. OBJECTIVES: We evaluated the interrelationship of phylogenetic inference with epidemiological and laboratory data for HIV-1 isolates circulating in Pernambuco, Northeast Region-Brazil. STUDY DESIGN: A total of 168 HIV-1 pol sequences were analysed, 64 were obtained from 2002-2003, and 104, from 2007-2009. Socio-demographic, clinical, and behavioural data were obtained from medical records. Laboratory testing enabled the determination of recent HIV-1 infections and co-infections with HBV, HCV, HTLV, or syphilis. Surveillance drug-resistance mutation analysis and antiretroviral susceptibility profiling were performed using HIV Drug-Resistance Database. RESULTS: HIV-1 non-B was associated with female, lower education, lower viral loads, and higher T cell counts mean. Frequencies of co-infection HIV-HBV, HIV-HCV, and HIV-syphilis were 27.8% (95% CI: 19.8-37.7), 1.04% (95% CI: 0.05-5.00) and 14.7% (95% CI: 8.6-23.0), respectively. Drug-resistant mutations rate was 2.98% (95% CI: 1.10-6.47). HIV-HBV subtype B co-infection was associated with men who have sex with men (MSM), higher education, higher viral loads and males. HIV-syphilis subtype non-B co-infection was associated with MSM status, lower T cell counts and males. CONCLUSIONS: Data showed the importance of molecular characterisations of the HIV-1 epidemic and its relation with epidemiological and clinical characteristics of the population, as well as its association with other infectious diseases, so they can effort to improve preventive measures for health services and more information about the progress and effects of the epidemic in Northeastern-Brazil.

Estimation of HIV incidence in two Brazilian municipalities, 2013.

OBJECTIVE: To estimate HIV incidence in two Brazilian municipalities, Recife and Curitiba, in the year of 2013. METHODS: The method for estimating incidence was based on primary information, resulting from the Lag-Avidity laboratory test for detection of recent HIV infections, applied in a sample of the cases diagnosed in the two cities in 2013. For the estimation of the HIV incidence for the total population of the cities, the recent infections detected in the research were annualized and weighted by the inverse of the probability of HIV testing in 2013 among the infected and not diagnosed cases. After estimating HIV incidence for the total population, the incidence rates were estimated by sex, age group, and exposure category. RESULTS: In Recife, 902 individuals aged 13 years and older were diagnosed with HIV infection. From these, 528 were included in the study, and the estimated proportion of recent infections was 13.1%. In Curitiba, 1,013 people aged 13 years and older were diagnosed, 497 participated in the study, and the proportion of recent infections was 10.5%. In Recife, the estimated incidence rate was 53.1/100,000 inhabitants of 13 years and older, while in Curitiba, it was 41.1/100,000, with male-to-female ratio of 3.5 and 2.4, respectively. We observed high rates of HIV incidence among men who have sex with men, of 1.47% in Recife and 0.92% in Curitiba. CONCLUSIONS: The results obtained in the two cities showed that the group of men who have sex with men are disproportionately subject to a greater risk of new infections, and indicate that strategies to control the spread of the epidemic in this population subgroup are essential and urgent. OBJETIVO: Estimar a incidência de HIV em dois municípios brasileiros, Recife e Curitiba, no ano de 2013. MÉTODOS: O método de estimação da incidência foi baseado em informações primárias, resultantes do ensaio laboratorial Lag-Avidity para detecção de infecções recentes do HIV, aplicado em uma amostra dos casos diagnosticados nas duas cidades em 2013. Para a estimação da incidência de HIV para a população total das cidades, as infecções recentes detectadas na pesquisa foram anualizadas e ponderadas pelo inverso da probabilidade de teste de HIV no ano de 2013 entre os casos infectados e não diagnosticados. Após a estimação da incidência de HIV para a população total, foram estimadas as taxas de incidência por sexo, faixa de idade e categoria de exposição. RESULTADOS: Em Recife, foram diagnosticados 902 indivíduos de 13 anos e mais com infecção de HIV. Desses, 528 foram incluídos no estudo, e a proporção estimada de infecções recentes foi de 13,1%. Em Curitiba, foram diagnosticadas 1.013 pessoas de 13 anos e mais, 497 participaram do estudo, e a proporção de infecções recentes foi de 10,5%. Em Recife, a taxa de incidência estimada foi de 53,1 por 100 mil habitantes de 13 anos e mais, enquanto em Curitiba, de 41,1 por 100 mil, com razão do sexo masculino para o feminino de 3,5 e 2,4, respectivamente. Foram evidenciadas elevadas taxas de incidência de HIV entre homens que fazem sexo com homens, de 1,47% em Recife e 0,92% em Curitiba. CONCLUSÕES: Os resultados obtidos nas duas cidades mostraram que o grupo dos homens que fazem sexo com homens está desproporcionalmente sujeito ao maior risco de novas infecções, e indicam que estratégias para controle da disseminação da epidemia nesse subgrupo populacional são essenciais e urgentes.

HIV-1 incidence among people seeking voluntary counseling and testing centers, including pregnant women, in Pernambuco State, Northeast Brazil.

The HIV-1 epidemic in Brazil has displayed new characteristics over time, with an increase in heterosexual transmission and a decline in the male-to-female ratio in AIDS cases. HIV screening was offered to patients attending the Voluntary Counseling and Testing Center in Paulista, Greater Metropolitan Recife, Pernambuco State, in Northeast Brazil, to determine HIV-1 incidence. BED capture enzyme immunoassay (BED-CEIA) was used to measure HIV-1 incidence, comparing it to the AxSYM avidity index method (Ax-AI). From 2006 to 2009, 14,014 individuals were tested, and only 18 pregnant women were diagnosed with HIV infection, resulting in 0.15% annual incidence (95%CI: 0-0.33), significantly lower than in men (1.03; 95%CI: 0.45-1.61) and non-pregnant women (0.50; 95%CI: 0.11-0.89). Despite the low HIV-1 incidence in pregnant women, the high rate of recent infection detected during prenatal care emphasizes the need to increase measures to prevent vertical transmission.

Epidemiology of travelers' diarrhea: details of a global survey.

BACKGROUND: Recent epidemiologic data on travelers' diarrhea (TD) are essential for the evaluation of conventional and future prophylactic and therapeutic measures. METHODS: To determine the epidemiology, including risk factors, impact and quality-of-life evaluation of TD, a cross-sectional survey was conducted over 12 months at the airports of Mombasa (Kenya), Goa (India), Montego Bay (Jamaica) and Fortaleza (Brazil) by distributing questionnaires to visitors just prior to their flying home. The study period was March 1996 to July 1998. RESULTS: Overall, 73,630 short-term visitors completed a questionnaire. The total diarrhea attack rate varied between a high of 54.6% in Mombasa and a low of 13.6% in Fortaleza, but only between 31.5% and 5.4% of all travelers had classic TD. The 14-day incidence rates varied between 19.5% and 65.7%. Few travelers meticulously avoided potentially dangerous food items, although in India and Kenya most travelers avoided those considered most dangerous. Risk factors were stays exceeding 1 week, age between 15 and 30 years, and residence in the UK. The impact, measured as incapacity or quality-of-life scores, was very considerable. CONCLUSIONS: TD continues to affect vacationers and business travelers as frequently as it did some 20 years ago. Compliance with recommendations to reduce exposure to pathogens by avoiding dangerous food items is poor among travelers from all countries. Implementation of food safety education programs may be difficult to achieve.

Comparison among the BED capture enzyme immunoassay test and AxSYM avidity index assay for determining recent HIV infection and incidence in two Voluntary Counselling and Testing Centres in Northeast Brazil.

The aims of this study were to compare the automated AxSYM avidity assay index with the BED capture enzyme immunoassay test and to calculate the HIV-1 incidence using the BED capture enzyme immunoassay and AxSYM avidity assay index algorithms within a population seeking the Voluntary Counselling and Testing Centres in two municipalities in the Metropolitan Region of Recife, Northeast of Brazil. An analysis was conducted in 365 samples that tested positive for HIV infection from frozen serum collected during the period 2006-2009. There was a similar proportion of males and females; most patients were heterosexual (86%) with a median age of 29 years. Of the 365 samples, 102 (28%) and 66 (18.1%) were identified as recent infections by BED capture enzyme immunoassay and AxSYM avidity assay index, respectively. The HIV-1 total incidence in the BED capture enzyme immunoassay and AxSYM avidity assay index algorithms were: 0.79 (95% CI: 0.60-0.98) and 0.34 (95% CI: -0.04 to 0.72), respectively. Incidence was higher among men. There was good agreement between the tests, with a kappa of 0.654 and a specificity of 95.8%. AxSYM avidity assay index may be helpful in improving the quality of the estimates of recent HIV infection and incidence, particularly when used in a combined algorithm with BED capture enzyme immunoassay.

Recent HIV infection rates among HIV positive patients seeking voluntary counseling and testing centers in the metropolitan region of Recife - PE, Brazil.

UNLABELLED: The BED capture enzyme immunoassay test makes it possible to determine whether individuals were recently infected with HIV. OBJECTIVE: In this study, the overall HIV and recent infections prevalences were determined at five Voluntary Counseling and Testing (VCT) centers, in the Metropolitan Region of Recife, Northeastern of Brazil. MATERIAL AND METHODS: A cross-sectional study was conducted among users of five VCTs in the metropolitan region of Recife between July 2007 and April 2009. Out of the individuals who tested positive for HIV, 169 were analyzed to assess the prevalence of recent infection by means of the BED-CEIA (BED-Calypte®). RESULTS: Out of 46,696 individuals tested 916 (1.96%) turned out positive for HIV infection The highest prevalence was in Recife (3.9%). The prevalence was higher among males (3.93%), and men who have sex with men (MSM) (12.4%). The frequency of recent infections among the 169 subjects evaluated was 23.7%. Recent infections were more common among individuals under 25 years of age. There was slight predominance of men and higher frequency of heterosexuals in both groups, but still a significant portion of MSM (33%). Subtype B predominated, followed by a high proportion of subtype F. CONCLUSIONS: Recent infection occurs mainly among young individuals and heterosexuals, despite a significant proportion of recent infection among MSM. These results suggest that preventive actions aimed at the MSM community remains a challenge and efforts focusing this group should continue to be a priority.

Estimation of HIV incidence in two Brazilian municipalities, 2013 / Estimação da incidência de HIV em dois municípios brasileiros, 2013

ABSTRACT OBJECTIVE To estimate HIV incidence in two Brazilian municipalities, Recife and Curitiba, in the year of 2013. METHODS The method for estimating incidence was based on primary information, resulting from the Lag-Avidity laboratory test for detection of recent HIV infections, applied in a sample of the cases diagnosed in the two cities in 2013. For the estimation of the HIV incidence for the total population of the cities, the recent infections detected in the research were annualized and weighted by the inverse of the probability of HIV testing in 2013 among the infected and not diagnosed cases. After estimating HIV incidence for the total population, the incidence rates were estimated by sex, age group, and exposure category. RESULTS In Recife, 902 individuals aged 13 years and older were diagnosed with HIV infection. From these, 528 were included in the study, and the estimated proportion of recent infections was 13.1%. In Curitiba, 1,013 people aged 13 years and older were diagnosed, 497 participated in the study, and the proportion of recent infections was 10.5%. In Recife, the estimated incidence rate was 53.1/100,000 inhabitants of 13 years and older, while in Curitiba, it was 41.1/100,000, with male-to-female ratio of 3.5 and 2.4, respectively. We observed high rates of HIV incidence among men who have sex with men, of 1.47% in Recife and 0.92% in Curitiba. CONCLUSIONS The results obtained in the two cities showed that the group of men who have sex with men are disproportionately subject to a greater risk of new infections, and indicate that strategies to control the spread of the epidemic in this population subgroup are essential and urgent.

RESUMO OBJETIVO Estimar a incidência de HIV em dois municípios brasileiros, Recife e Curitiba, no ano de 2013. MÉTODOS O método de estimação da incidência foi baseado em informações primárias, resultantes do ensaio laboratorial Lag-Avidity para detecção de infecções recentes do HIV, aplicado em uma amostra dos casos diagnosticados nas duas cidades em 2013. Para a estimação da incidência de HIV para a população total das cidades, as infecções recentes detectadas na pesquisa foram anualizadas e ponderadas pelo inverso da probabilidade de teste de HIV no ano de 2013 entre os casos infectados e não diagnosticados. Após a estimação da incidência de HIV para a população total, foram estimadas as taxas de incidência por sexo, faixa de idade e categoria de exposição. RESULTADOS Em Recife, foram diagnosticados 902 indivíduos de 13 anos e mais com infecção de HIV. Desses, 528 foram incluídos no estudo, e a proporção estimada de infecções recentes foi de 13,1%. Em Curitiba, foram diagnosticadas 1.013 pessoas de 13 anos e mais, 497 participaram do estudo, e a proporção de infecções recentes foi de 10,5%. Em Recife, a taxa de incidência estimada foi de 53,1 por 100 mil habitantes de 13 anos e mais, enquanto em Curitiba, de 41,1 por 100 mil, com razão do sexo masculino para o feminino de 3,5 e 2,4, respectivamente. Foram evidenciadas elevadas taxas de incidência de HIV entre homens que fazem sexo com homens, de 1,47% em Recife e 0,92% em Curitiba. CONCLUSÕES Os resultados obtidos nas duas cidades mostraram que o grupo dos homens que fazem sexo com homens está desproporcionalmente sujeito ao maior risco de novas infecções, e indicam que estratégias para controle da disseminação da epidemia nesse subgrupo populacional são essenciais e urgentes.

Frequency of primary resistance to antiretroviral drugs and genetic variability of HIV-1 among infected pregnant women recently diagnosed in Luanda-Angola.

The determination of the prevalence of primary resistance to antiretroviral therapy in different places of the world is of extreme importance in molecular epidemiology monitoring, and it can guide the initial patient therapy in a given geographical area. The frequency of drug resistance mutations (DRM) and the genetic variability of HIV-1 isolates from newly diagnosed HIV-infected pregnant women attending the antenatal clinics of the Lucrecia Paim and Augusto N'Gangula maternities, Luanda-Angola, were determined. Thirty five out of 57 samples (61.4%) were sequenced and one mutation associated with resistance to nucleoside reverse transcriptase inhibitors was detected. Additionally, two mutations associated with resistance to non-nucleoside reverse transcriptase inhibitors were also detected. No primary mutations associated with protease inhibitors (PI) were found. Subtypes A1, C, D, F1, G, H, CRF 13, CRF 37, and other mosaics were detected.

Antiretroviral resistance in individuals presenting therapeutic failure and subtypes of the human immunodeficiency virus type 1 in the Northeast Region of Brazil.

This study aimed to analyze human immunodeficiency virus (HIV) mutation profiles related to antiretroviral resistance following therapeutic failure, and the distribution of hiv subtypes in the Northeast Region of Brazil. A total of 576 blood samples from AIDS patients presenting therapeutic failure between 2002 and 2004 were analyzed. The genotyping kit viroSeq was used to perform viral amplification in order to identify mutations related to hiv pol gene resistance. An index of 91.1% of the patients presented mutations for nucleoside reverse transcriptase inhibitors (nrti), 58.7% for non-nucleoside reverse transcriptase inhibitors (nnrti), and 94.8% for protease inhibitors (pi). The most prevalent mutations were 184V and 215E for nrti, 103N and 190A for nnrti. Most mutations associated with PIs were secondary, but significant frequencies were observed in codons 90 (25.2%), 82 (21.1%), and 30 (16.2%). The resistance index to one class of antiretrovirals was 14%, to two classes of antiretrovirals 61%, and to three classes 18.9%. Subtype B was the most prevalent (82.4%) followed by subtype F (11.8%). The prevalence of mutations related to nrti and nnrti was the same in the two subtypes, but codon analysis related to PI showed a higher frequency of mutations in codon 63 in subtype B and in codon 36 in subtype F. The present study showed that there was a high frequency of primary mutations, which offered resistance to nrti and nnrti. Monitoring patients with treatment failure is an important tool for aiding physicians in rescue therapy.
