RESUMO Objetivo: Descrever a implementação e os resultados da colaborativa PROADI-SUS, do Ministério da Saúde Brasileiro, para redução das infecções relacionadas à assistência à saúde: pneumonia associada à ventilação mecânica, infecção primária da corrente sanguínea associada ao cateter venoso central e infecção do trato urinário associada ao cateter vesical de demora. Métodos: Estudo observacional prospectivo que pesquisou as etapas da implementação e dos resultados por 18 meses, em cinco unidades de terapia intensiva de Recife. As reduções de infecções relacionadas à assistência à saúde em cada unidade foram calculadas pelas medianas anteriores comparadas ao período do estudo. Resultados: A meta de redução das três infecções relacionadas à assistência à saúde, ou seja, 30% em 18 meses, foi obtida em no mínimo uma das infecções relacionadas à assistência à saúde nas cinco unidades de terapia intensiva, sendo ainda atingida para duas infecções relacionadas à assistência à saúde em dois hospitais e nas três infecções relacionadas à assistência à saúde em apenas um hospital; este último atingiu a meta prevista para 36 meses. Foram ações consideradas essenciais pelas equipes gestoras locais a implantação dos bundles e o acompanhamento dos resultados pelos profissionais. Também, aquisição de insumos e disponibilização junto aos leitos, sinalização, checklists, conscientização da equipe, adaptação, criação de times, treinamento e comemoração de conquistas foram avaliados como relevantes para redução das infecções relacionadas à assistência à saúde. Conclusão: A colaborativa reduziu infecções relacionadas à assistência à saúde, apesar da adesão parcial aos bundles. A hipótese é a de que o êxito se relacione com a metodologia do projeto e equipes multiprofissionais motivadas, especialmente a enfermagem.

ABSTRACT Objective: To describe the implementation and results of the collaborative PROADI-SUS project by the Brazilian Ministry of Health to reduce healthcare-associated infections: ventilator-associated pneumonia, primary central line-associated bloodstream infection and catheter-associated urinary tract infections. Methods: This was a prospective observational study that investigated the implementation stages and outcomes during 18 months in five intensive care units in the city of Recife. Reductions in healthcare-associated infections in each unit were calculated using previous medians compared to those of the study period. Results: The goal of reducing the three healthcare-associated infections, i.e., 30% in 18 months, was achieved in at least one of the healthcare-associated infections and was also achieved for two healthcare-associated infections in two hospitals and three healthcare-associated infections in just one hospital; the latter reached the target of 36 months. Implementing the bundles and monitoring the results by the professionals were considered essential actions by the local management teams. In addition, the acquisition of supplies and their availability alongside the beds, signage, checklists, staff awareness, adaptation, team building, training and celebration of achievements were assessed as being relevant for reducing healthcare-associated infections. Conclusion: The collaborative approach reduced healthcare-associated infections, despite partial adherence to the bundles. The hypothesis is that success is related to the project methodology and motivated multidisciplinary teams, especially nursing teams.

Resumo Fundamento Pacientes com HIV têm maior probabilidade de apresentar doenças cardiovasculares quando comparados à população em geral. Objetivo Este foi um estudo de caso-controle que teve como objetivo avaliar quais fatores estavam associados a uma redução na espessura médio-intimal da carótida (IMT) da carótida e ao aumento na dilatação mediada por fluxo (DMF) da artéria braquial em pacientes com HIV que receberam atorvastatina + aspirina por um período de 6 meses. Métodos Foi realizada uma análise secundária de um ensaio clínico, que incluiu pessoas vivendo com HIV e baixo risco cardiovascular. Um total de 38 pacientes alocados para o braço de intervenção e tratados por 6 meses com uma combinação de atorvastatina + aspirina foram incluídos. Todos os participantes foram submetidos a ultrassonografia da carótida e da artéria braquial, tanto no início quanto no final do estudo. Os casos que responderam com aumento >10% da dilatação braquial (DMF) e redução da espessura médio-intimal da carótida (IMT) foram considerados casos, e aqueles que não responderam foram considerados controles. Avaliamos os fatores associados às respostas positivas obtidas através da IMT e DMF. Resultados A redução do IMT não se associou significativamente a nenhum dos fatores de risco avaliados: idade (p = 0,211), sexo (p = 0,260), tabagismo (p = 0,131) ou tempo de diagnóstico do HIV (p = 0,836). Um aumento na DMF foi significativamente associado com a idade entre aqueles na faixa etária de 40-59 anos, p = 0,015 (OR = 4,37; IC 95%: 1,07-17,79). Conclusões Os indivíduos mais velhos foram mais propensos a apresentar um aumento na DMF após 6 meses de tratamento com atorvastatina + aspirina.

Abstract Background Patients with HIV are more likely to present with cardiovascular disease when compared to the general population. Objective This was a case-control study that aimed to assess which factors were associated with a reduction in the carotid intima-media thickness (IMT) and an increase in the brachial artery flow-mediated dilation (FMD) in HIV patients who received atorvastatin + aspirin during a period of 6 months. Methods A secondary analysis of a clinical trial was conducted, which included people living with HIV infection and low cardiovascular risk. A total of 38 patients allocated to the intervention arm and treated for 6 months with a combination of atorvastatin + aspirin were included. All participants underwent a carotid and brachial artery ultrasound, both at the beginning and the end of the study. Cases that responded with an increase of >10% of the brachial dilatation (FMD) and reduction of the carotid intima-media thickness (IMT) were considered cases, and those who did not respond were considered controls. We assessed the factors associated with the positive responses obtained through IMT and FMD. Results A reduction in the IMT was not significantly associated with any of the evaluated risk factors: age (p=0.211), gender (p=0.260), smoking (p=0.131) or time since HIV diagnosis (p=0.836). An increase in the FMD was significantly associated with age amongst those in the 40-59 age group, p = 0.015 (OR = 4.37; 95% CI: 1.07-17.79). Conclusions Older individuals were more likely to present with an increased FMD after 6 months of treatment with atorvastatin + aspirin.

ABSTRACT The efficacy of direct-acting antivirals (DAAs) in the treatment of chronic hepatitis C (CHC) in liver transplant recipients is poorly understood, and several factors, including immunosuppression, drug interactions, elevated viraemia, and intolerance to ribavirin (RBV), can reduce cure rates. We conducted a real-life study on liver transplant recipients with CHC treated with a combination of sofosbuvir (SOF) and daclatasvir (DCV) or simeprevir (SIM), with or without RBV, followed-up for 12 to 24 weeks. The treatment effectiveness was assessed by determining the sustained virological response (SVR) rates at 12 or 24 weeks after the treatment cessation. Eighty-four patients were evaluated, with a mean age of 63.4 ± 7.4 years, HCV genotype 1 being the most prevalent (63.1%). Nineteen patients (22.7%) had mild fibrosis (METAVIR < F2) and 41 (48.8%) significant fibrosis (METAVIR ≥ F2). The average time between liver transplantation and the start of treatment was 4 years (2.1-6.6 years). The SOF + DCV regimen was used in 58 patients (69%). RBV in combination with DAAs was used in seven patients (8.3%). SVR was achieved in 82 patients (97.6%), and few relevant adverse events could be attributed to DAA therapy, including a patient who stopped treatment due to a headache. There was a significant reduction in ALT, AST, GGT and FA levels, or the APRI index after 4 weeks of treatment, which remained until 12/24 weeks post-treatment. DAA treatment of CHC in liver-transplanted patients achieved a high SVR rate and resulted in the normalization of serum levels of liver enzymes.

Resumo Fundamento: As pessoas que vivem com HIV têm um risco aumentado de doença cardiovascular e espessamento da carótida, devido à inflamação causada pelo vírus, à terapia antirretroviral e a outros fatores de risco. No entanto, poucos estudos observaram a ocorrência de doenças cardiovasculares e espessamento carotídeo na população soropositiva com baixo risco cardiovascular e carga viral indetectável. Objetivos: Avaliar a associação entre níveis de marcadores inflamatórios e espessura da carótida em pessoas vivendo com HIV, sob terapia antirretroviral e com baixo risco cardiovascular. Métodos: Para determinar o baixo risco cardiovascular em ambos os grupos (indivíduos infectados e não-infectados pelo HIV), foi utilizado o Escore de Risco de Framingham. Os marcadores inflamatórios (IFN-γ, TNF-α, IL-1β, IL-6, sVCAM-1 e sICAM-1) foram avaliados por citometria de fluxo. A espessura da carótida (mm) foi mensurada por meio de ultrassom com Doppler. O nível de significância foi de p < 0,05. Resultados: Em pessoas vivendo com HIV, a idade e o tabagismo foram associados a alterações da espessura da carótida. No grupo não-HIV, idade e níveis mais altos de colesterol total e LDL foram associados ao aumento da espessura da carótida. Utilizando a análise multivariada, observou-se associação significativa entre os níveis de TNF-α e IL-1β e maior chance de desenvolvimento de aterosclerose no grupo com HIV. Conclusão: Ambos os grupos têm risco semelhante de desenvolver doença cardiovascular, portanto, nosso estudo demonstra que indivíduos HIV-positivos com carga viral indetectável em terapia antirretroviral sem inibidores de protease e com baixo risco cardiovascular não apresentam diferenças na espessura da carótida em relação aos indivíduos não-infectados.

Abstract Background: People living with HIV are at increased risk of cardiovascular disease and carotid thickness, due to the inflammation caused by the virus, the antiretroviral therapy, and other risk factors. However, few studies have observed the occurrence of cardiovascular diseases and carotid thickness in HIV-positive population at low cardiovascular risk and with undetectable viral load. Objectives: To evaluate the association between levels of inflammatory markers and carotid thickness in people living with HIV, under antiretroviral therapy and at low cardiovascular risk. Methods: To determine low cardiovascular risk in both groups (HIV infected and non-infected individuals), the Framingham Risk Score was used. Inflammatory markers (IFN-γ, TNF-α, IL-1β, IL-6, sVCAM-1, and sICAM-1) were assessed using flow cytometry. Carotid thickness (mm) was measured using Doppler ultrasound. Level of significance was p < 0.05. Results: In People living with HIV, age and smoking status were associated with carotid thickness alterations. In the non-HIV group, age, higher total cholesterol, and LDL levels were associated with increased carotid thickness. Using the multivariate analysis, a significant association between TNF-α and IL- 1( levels, and a higher chance of atherosclerosis development in HIV group were observed. Conclusions: Both groups have a similar risk for developing cardiovascular disease, therefore our study demonstrates that HIV-positive individuals with undetectable viral load in antiretroviral therapy without protease inhibitors and with low cardiovascular risk do not present differences in carotid thickness in relation to uninfected individuals.

Resumo Fundamento: Pessoas que vivem com o HIV (HIV +) têm maior prevalência de aterosclerose e a desenvolvem mais precocemente do que a população geral. Objetivos: Foi avaliar e comparar as prevalências de aterosclerose avaliada pela medida da espessura mediointimal (EMI) das carótidas comuns e femorais, e do índice tornozelo-braquial (ITB) nos grupos controle e HIV com e sem inibidores de protease (IPs). Métodos: Foram incluídas 80 pessoas com HIV + [40 usavam IPs e 40 não] e 65 controles. O diagnóstico de aterosclerose foi determinado pela medição da EMI (carótidas e femorais) e do ITB. Fatores de risco clássicos para aterosclerose e específicos para o HIV foram comparados entre os grupos, usando testes estatístcos. O valor de p ≤ 0,05 foi cosiderado significativo. Resultados: A EMI > P75 ou presença de placa foi mais elevada no grupo de HIV sem IP que no controle (37,5% vs 19%, p = 0,04). A análise comparativa mostrou diferença significativa (p=0,014) na EMI nas artérias carótidas entre HIV + com IPs (0,71 ± 0,28 mm), sem IPs (0,63 ± 0,11 mm) e controles (0,59 ± 0,11 mm), A EMI na femoral não teve diferença significante entre os grupos. Não houve diferença significante entre os grupos controle e de HIV + quanto ao ITB. No entanto, observou-se uma diferença significativa (p=0,015) no ITB entre os grupos HIV + sem IPs (1,17 [1,08 - 1,23]), e controles [1,08 (1,07 - 1,17)]. Conclusão: Em pacientes com HIV, a aterosclerose é mais prevalente e parece ocorrer mais precocemente, com características distintas, em comparação a indivíduos HIV-negativos.

Abstract Background: The prevalence of atherosclerosis is higher in HIV-positive people, who also experience it earlier than the general population. Objectives: To assess and compare the prevalence of atherosclerosis evaluated by the intima-media thickness of carotid and femoral arteries, and by the ankle-brachial pressure index (ABPI) in HIV patients treated or not treated with protease inhibitors (PIs) and controls. Methods: Eighty HIV+ subjects (40 using PIs and 40 not using PIs) and 65 controls were included in the study. Atherosclerosis was diagnosed by (carotid and femoral) ITM measurement and ABPI. Classical risk factors for atherosclerosis and HIV were compared between the groups by statistical tests. A p ≤ 0.05 was considered significant. Results: An IMT > P75 or the presence of plaque was higher in the HIV+ than in the control group (37.5% vs 19%, p = 0.04). Comparative analysis showed a significant difference (p=0.014) in carotid IMT between HIV+ with PIs (0.71 ± 0.28 mm), without PIs 0.63 ± 0.11 mm and, and controls (0.59 ± 0.11 mm). There was no significant difference in femoral IMT between the groups or in ABPI between HIV+ subjects and controls. However, a significant difference (p=0.015) was found between HIV+ patients not treated with PIs (1.17 [1.08 - 1.23]), and controls 1.08 [1.07 - 1.17]). Conclusion: In HIV patients, atherosclerosis is more prevalent and seems to occur earlier with particular characteristics compared with HIV-negative subjects.

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.

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.

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.

INTRODUCTION: The incidence of ischemic heart disease is higher in patients with HIV/AIDS. However, the frequency of angina pectoris in these patients is still not known. Literature about this subject is still scarce. OBJECTIVE: To evaluate the prevalence of angina pectoris and risk factors for coronary disease and to examine the association between traditional risk factors and HIV-related risk factors and angina pectoris. METHOD: An epidemiological cross-sectional study, analyzed as case-control study, involving 584 patients with HIV/AIDS. Angina pectoris was identified by Rose questionnaire, classified as definite or possible. Information regarding risk factors was obtained through a questionnaire, biochemical laboratory tests, medical records and anthropometric measures taken during consultations at AIDS treatment clinics in Pernambuco, Brazil, from June 2007 to February 2008. To adjust the effect of each factor in relation to others, multiple logistic regression was used. RESULTS: There was a preponderance of men (63.2%); mean ages were 39.8 years for men, 36.8 years for women. The prevalence of definite and possible angina were 11% and 9.4%, respectively, totaling 20.4%, with independent associations between angina and smoking (OR = 2.88; 95% CI: 1.69-4.90), obesity (OR = 1.62; 95% CI: 0.97-2.70), family history of heart attack (OR = 1.70; 95% CI: 1.00-2.88), low schooling (OR = 2.11; 95% CI: 1.24-3.59), and low monthly income (OR = 2.93; 95% CI: 1.18-7.22), even after adjustment for age. CONCLUSION: This study suggests that angina pectoris is underdiagnosed, even in patients with medical monitoring, revealing lost opportunities in identification and prevention of cardiovascular morbidity.

FUNDAMENTO: A terapia antirretroviral aumentou drasticamente a expectativa de vida em pacientes com HIV/AIDS, embora a aterosclerose esteja associada a uma terapia de longo prazo. OBJETIVO: Investigar a prevalência de aterosclerose em pacientes com AIDS submetidos à terapia antirretroviral e a influência de tratamentos de diferentes regimes e durações. MÉTODOS: Pacientes com HIV/AIDS foram abordados durante consultas de rotina. Aqueles que estiveram em terapia antirretroviral por, pelo menos, dois anos tiveram o sangue coletado para análise do perfil lipídico e da glicemia em jejum e foram submetidos à tomografia computadorizada cardíaca para quantificação do escore de cálcio dentro de seis dias, no máximo. A aterosclerose foi definida como escore de cálcio maior que zero (CAC > 0). Fatores de risco tradicionais, síndrome metabólica e o escore de Framingham foram analisados. RESULTADOS: Cinquenta e três pacientes realizaram tomografia computadorizada cardíaca: 50,94% eram do sexo masculino, com idade média de 43,4 anos; 20% tinham hipertensão; 3,77% tinham diabetes; 67,92% tinham hipercolesterolemia; 37,74% tinham hipertrigliceridemia; 47,17% tinham HDL baixo; 24,53% atenderam aos critérios para síndrome metabólica; 96,23% foram classificados no escore de Framingham como "baixo risco"; e 18,87% eram tabagistas. A duração média do tratamento antirretroviral foi de 58,98 meses. A aterosclerose coronária ocorreu em 11 pacientes (20,75%). A duração da terapia antirretroviral não se relacionou à aterosclerose (p = 0,41), e não houve diferenças significativas entre os diferentes esquemas antirretrovirais (p = 0,71). Entre os fatores de risco tradicionais, o tabagismo (OR = 27,20; p = 0,023) e a idade (OR = 20,59; p = 0,033) foram significativos na presença de aterosclerose. Havia tendência para uma associação positiva da aterosclerose com a hipercolesterolemia (OR = 8,30; p = 0,0668). CONCLUSÃO: Os fatores associados à aterosclerose foram idade, tabagismo e hipercolesterolemia. A duração e o tipo de terapia antirretroviral não influenciaram a prevalência da aterosclerose.

BACKGROUND: Antiretroviral therapy has dramatically increased life expectancy in patients with HIV/AIDS although atherosclerosis has been associated with long-standing therapy. OBJECTIVE: To investigate the prevalence of atherosclerosis in patients with AIDS undergoing antiretroviral therapy and the influence of different schemes and duration of treatment. METHODS: HIV/AIDS patients were approached during routine consultations. Those who had been on antiretroviral therapy for at least two years had their blood collected for analysis of lipid profile and fasting glycemia and underwent cardiac CT for quantification of calcium score within six days at the most. Atherosclerosis was defined as calcium score greater than zero (CAC > 0). Traditional risk factors, metabolic syndrome and Framingham score were analyzed. RESULTS: Fifty-three patients performed cardiac CT. Twenty-seven (50.94%) were male, mean age 43.4 years; 20.00% had hypertension, 3.77% diabetes, 67.92% hypercholesterolemia, 37.74% hypertriglyceridemia and 47.17% low HDL. Thirteen (24.53%) met criteria for metabolic syndrome and 96.23% were classified in Framingham score as "low risk." Ten patients (18.87%) were smokers. Mean duration of antiretroviral treatment was 58.98 months. Coronary atherosclerosis occurred in 11 (20.75%) patients. Duration of antiretroviral therapy was not related to atherosclerosis (p = 0.41) and there were no significant differences between different antiretroviral regimens (p = 0.71). Among traditional risk factors, smoking (OR = 27.20; p = 0.023) and age (OR = 20.59; p = 0.033) were significant in the presence of atherosclerosis. There was a trend towards a positive association of atherosclerosis with hypercholesterolemia (OR = 8.30; p = 0.0668). CONCLUSION: Factors associated with atherosclerosis were age, smoking and hypercholesterolemia. Duration and type of antiretroviral therapy had no influence on the prevalence of atherosclerosis.

FUNDAMENTO: Hipertensão arterial sistêmica (HAS) é fator de risco modificável, cujo controle pode reduzir doença cardiovascular nos pacientes com vírus da imunodeficiência adquirida (HIV). OBJETIVO: Estimar a prevalência de HAS e descrever as características dos pacientes com HAS e pré-hipertensão infectados pelo HIV/AIDS. MÉTODOS: Estudo seccional alinhado a uma coorte de pacientes com HIV/AIDS. Considerou-se hipertensão em níveis > 140/90 mmHg ou uso de anti-hipertensivos e pré-hipertensão em níveis > 120/80 mmHg. RESULTADOS: Dos 958 pacientes, 388 (40,5%) eram normotensos, 325 (33,9%) pré-hipertensos e 245 (25,6%) hipertensos. Desses 245 pacientes, 172 (70,2%) sabiam ser hipertensos e 36 (14,8%) apresentavam pressão arterial controlada. Tiveram diagnóstico de HAS após o diagnóstico do HIV 62 pacientes (54,4%). Lipodistrofia ocorreu em 95 (46,1%) dos pacientes, já sobrepeso/obesidade em 129 (52,7%). Utilização de antirretrovirais ocorreu em 184 (85,9%), 89 (41,6%) com inibidores de protease (IP) e 95 (44,4%) sem IP. Utilizavam antivirais > 24 meses 74,7%. Idade, antecedentes familiares de hipertensão, circunferência abdominal, índice de massa corporal e triglicerídeos foram maiores entre pacientes hipertensos. Tempo de infecção pelo HIV, contagem de linfócitos CD4, carga viral, tempo e tipo de esquema antirretroviral foram semelhantes nos hipertensos e pré-hipertensos. CONCLUSÃO: A elevada frequência de hipertensos não controlados e de riscos cardiovasculares nos infectados pelo HIV apontam a necessidade de medidas preventivas e terapêuticas contra HAS nesse grupo.

BACKGROUND: Hypertension (HBP) is modifiable risk factor, whose control may reduce cardiovascular disease in patients with human immunodeficiency virus (HIV). OBJECTIVE: To estimate the prevalence of hypertension and describe the characteristics of patients with hypertension infected by HIV/AIDS. METHODS: A cross-sectional study aligned to a cohort of patients with HIV/AIDS. The study considered hypertension at levels > 140/90 mmHg or use of antihypertensive drugs and pre-hypertension at levels > 120/80 mmHg. RESULTS: Out of 958 patients, 388 (40.5%) were normotensive, 325 (33.9%) were pre-hypertensive, and 245 (25.6%) were hypertensive. Out of these 245 patients, 172 (70.2%) were aware of the fact there they were hypertensive, and 36 (14.8%) had blood pressure controlled. Sixty-two (62) patients (54.4%) were diagnosed with hypertension after HIV diagnosis. Lipodystrophy occurred in 95 (46.1%) patients; overweight/obesity in 129 (52.7%). Use of antiretrovirals occurred in 184 (85.9%), 89 (41.6%) with protease inhibitors (PI) and 95 (44.4%) without PI. Out of these patients, 74.7 used antivirals > 24 months. Age, family history of hypertension, waist circumference, body mass index and triglyceride levels were higher among hypertensive patients. Time of HIV infection, CD4 count, viral load, time and type of antiretroviral regimen were similar in hypertensive and prehypertensive patients. CONCLUSION: The high frequency of uncontrolled hypertensive patients and cardiovascular risks in HIV-infected patients point out to the need for preventive and therapeutic measures against hypertension in this group.

INTRODUCTION: Studies disagree as to whether there is a greater prevalence of hypertension among HIV/AIDS patients and the role of antiretroviral therapy. OBJECTIVE: Evaluate the prevalence of hypertension and risk factors in a cohort of HIV-infected patients, with emphasis on antiretroviral therapy. METHOD: Case-control study conducted at baseline of a cohort, between June/2007 and December/2008 in Pernambuco/Brazil. Blood pressure was classified as normal, prehypertension, and hypertension. RESULTS: Of 958 patients, 245 (25.6%) had hypertension (cases), 325 (33.9%) had prehypertension, and 388 (40.5%) were normotensive (controls). Comparison between hypertensive and normotensive patients showed that traditional factors, such as age > 40 (OR = 3.06, CI = 1.91-4.97), male gender (OR = 1.85, CI = 1.15-3.01), BMI > 25 (OR = 5.51, CI = 3.36-9.17), and triglycerides > 150 mg/dL (OR = 1.69, CI = 1.05-2.71), were independently associated with hypertension. Duration of antiretroviral therapy and CD4 > 200 cells/mm³ were associated with hypertension in univariate analysis, but did not remain in final model. Type of antiretroviral schema and lipodystrophy showed no association with hypertension. CONCLUSION: Hypertension in HIV/AIDS patients is partially linked to invariable factors, such as age and sex. Efforts should be directed toward controlling reversible factors, particularly excessive weight gain and unsuitable diet.

Women with human immunodeficiency virus (HIV) infection present a higher risk of infection by the human papillomavirus (HPV) and cervical cancer. To determine HPV genotypes and frequencies among HIV-positive women, an analytical cross-sectional study was carried out on 147 women (51 were pregnant and HIV-positive, 45 pregnant and HIV-negative and 51 HIV-positive and not pregnant), who were attended at a maternity hospital in Recife between April 2006-May 2007. They answered a questionnaire and underwent a gynaecological examination, with samples collected for HPV investigation by PCR, hybrid capture II, oncotic colpocytology (Papanicolau) and colposcopy. The frequency of HPV DNA was 85.3% (122/143), with a high proportion of HPV types that have been identified as high risk for cervical cancer. Among HIV-positive pregnant women, there was an HPV prevalence of 96% (48/50), of whom 60.4% (29/48) were high-risk. HPV 16, 58, 18, 66 and 31 were the most frequent types. Colpocytological abnormalities were observed in 35.3% (18/51) of HIV-positive non-pregnant women, 21.6% (11/51) of HIV-positive pregnant women and 13.3% (6/45) of HIV-negative pregnant women with a predominance of low-level lesions. A high prevalence of HPV infection was identified, especially with the high-risk types 16, 58, 18 and 66. This study identified high-risk HPV types in all three groups examined (HIV-positive pregnant women, HIV-negative pregnant women and HIV-positive not pregnant), characterising its distribution in this setting.

Introduction of highly active antiretroviral therapy has resulted in a significant reduction in morbimortality and significant changes in the causes of death among HIV/AIDS patients. For this reason, it has become essential to monitor survival and causes of death. We constructed a survival curve based on 597 adult patients notified as AIDS cases between 1997 and 2004, at the Hospital das Clínicas, Federal University of Pernambuco, Recife, Brazil. Among those patients, 150 (25%) progressed to death by December, 2005. Of these, 119 were studied in detail. The data were collected from notification files of the State Health Department and the State Mortality Information System, and were complemented by analysis of medical records. These 597 patients had a survival rate of 88%, 86% and 82% after one, two and five years, respectively, and a 75% likelihood of surviving to 1,984 days (66 months). Most of the deaths occurred during the first months after the diagnosis (median, 129 days). Patients who died were predominantly young men who had sexual exposure and came from Recife (the state capital) or its metropolitan region. When the patients were first seen, a large proportion had already presented severe signs of immunodeficiency. Comparing the patients within this group, the characteristics that were associated with lower survival were: male sex, hemoglobin < 10 mg/dL, lymphocytes < 1,000/mm³, use of fewer therapeutic drugs and antiretroviral regimens and non-introduction of protease inhibitors. Most of them died from AIDS-related diseases, particularly undefined respiratory infections.

JUSTIFICATIVA E OBJETIVOS: Para reduzir a mortalidade da sepse foram sugeridas intervenções agrupadas na campanha "Sobrevivendo à Sepse". O objetivo do estudo foi descrever a aplicação destas intervenções: controle glicêmico, corticóide no choque séptico, inotrópicos e drotrecogina-alfa na sepse. MÉTODO: Foram estudados 110 pacientes com sepse de sete hospitais do Recife/Brasil, que receberam drotrecogina alfa entre 2003/2006. Foram obtidos dados no manuseio da sepse conforme a campanha "Sobrevivendo a Sepse", uso da drotrecogina alfa, mortalidade aos 28 dias e sangramentos intensos. RESULTADOS: O APACHE II médio foi 25,6 e o SOFA médio foi 9,2; 95% dos pacientes apresentaram duas ou mais disfunções orgânicas e 98% apresentavam choque séptico; 56% tinham menos de 65 anos. O foco de infecção mais comum foi abdominal (48%) e respiratório (28%). Utilizou-se hidrocortisona em 61% dos pacientes, e 29(48,3%) morreram. Dos 38 pacientes com choque séptico prolongado que não o receberam, 28(73,7%) faleceram. Cerca de 97 pacientes apresentaram glicemia não controlada, destes, 65% atingiram controle glicêmico estrito e a mortalidade foi 51,6%. O ganho de fluídos variou de 600 ml a 9.400ml nas primeiras 24h. Disfunção miocárdica foi detectada em 30 pacientes. A infusão da drotrecogina-alfa foi iniciada em 24h em 45%, entre 24 e 48h em 35% e após 48h em 20%. Morte ocorreu em 57% e sangramento intenso em 9%. CONCLUSÕES: Observaram-se divergências entre as recomendações da campanha "Sobrevivendo à Sepse" e a prática clínica. A mortalidade foi 57%, similar à encontrada na literatura para pacientes com choque séptico, independente do uso da drotrecogina-alfa.

BACKGROUND AND OBJECTIVES: To face the high mortality of sepsis, interventions grouped as "Surviving Sepsis Campaign" have been suggested. The aim of the study was to describe the application of glycemic control, corticoid use in septic shock, inotropics and drotrecogin-alpha in sepsis. METHODS: We studied 110 patients with sepsis from Recife/Brazil, who received drotrecogin-alpha between 2003/2006. Data on management of sepsis considering Surviving Sepsis Campaign, drotrecogin-alpha, mortality at 28 days and severe bleeding were recorded. RESULTS: Mean APACHE II was 25.6 and mean SOFA was 9.2. Around 95% of the patients presented two or more organ dysfunctions and 98% presented septic shock. The majority (56%) were under 65 years. Abdominal (48%) and respiratory (28%) focus of infection were the most prevalent. Hydrocortisone was used in 61% of the patients, and 29 (48.3%) died. Of the 38 patients with prolonged shock that did not receive it, 28 (73.7%) died. Of the 97 patients who presented uncontrolled glycemia only 65% achieved strict glycemic control and the mortality was 51.6%. Fluid gain ranged from 600 ml to 9,400 ml in the first 24h. In only 30 patients was myocardial dysfunction detected. The infusion of drotrecogin alpha started within 24h in 45%, between 24 and 48h in 35% and after 48h in 20%. Death occurred in 57% and severe bleeding in 9%. CONCLUSIONS: Discrepancy between the recommendations of Surviving Sepsis Campaign and clinical practice was observed. Death rate was 57%, similar to that found in the literature for septic shock irrespective of the use of drotrecogin-alpha.
