Reduction of relative handgrip strength and cardiometabolic risk in individuals with HIV/AIDS

Abstract INTRODUCTION: Low handgrip strength (HS) is associated with cardiometabolic alterations that have affected people with HIV/AIDS. METHODS: This was a cross-sectional study performed in adults receiving antiretroviral treatment. HS was evaluated using a dynamometer and divided by body weight to obtain the relative strength. The association between relative HS and overweight, increased waist circumference (WC), high body fat percentage, glycemia, and lipid ratios were assessed using logistic regression. RESULTS: Low relative HS was identified in 35% of participants and associated with increased WC (odds ratio = 9.7; 95% confidence interval = 2.8-33.0). CONCLUSIONS: The prevalence of low HS was high and associated with increased WC.

Lifestyle and sleep patterns among people living with and without HIV/AIDS

Abstract INTRODUCTION: Negative lifestyles affect the health and quality of sleep of those living with and without HIV/AIDS. METHODS: Individuals were divided into two groups based on whether or not they were living with HIV/AIDS. RESULTS: Among the 20 participants, 95% displayed a poor lifestyle, and both groups demonstrated low-quality sleep with significant differences between groups in the early sleep variables, total sleep time, and sleep patterns. CONCLUSIONS: Both groups demonstrated similar behavior with unsatisfactory lifestyles, poor sleep quality, and irregular sleep patterns.

Analysis of the collagen fibers on autopsied patients' uterus with the Acquired Immunodeficiency Syndrome / Análise das fibras colágenas do útero de pacientes autopsiadas com a Síndrome da Imunodeficiência Adquirida

Abstract Objectives: to compare the percentage of collagen fibers in the autopsied women's uterine body and cervix with and without the Acquired Immunodeficiency Syndrome (Aids). Methods: 30 autopsied women's medical files were selected from 1988 to 2013. 30 fragments of the uterine body and 30 cervix were collected and then divided into two groups, 15 with Aids and 15 without, The quantification of the collagen fibers of the uterine body and cervix was performed on slides stained with picrosirius, using the KS-300® system. Results: the percentage of collagen fibers was lower for cervix (U=336544; p=0.001) and higher for the uterine body (U=308726,5; p=0.004) in the retroviral group when compared to the group without the disease. The percentage was higher for cervix than the uterine body in the group with Aids (t=0,4793; p=0.0031). the same result was found in the group without Aids (t=2,397; p=0.0637). Conclusions: the increase in the percentage of collagen fibers in the uterine body of women with Aids' indicates an immune response for viral infection and reveals a failure in keeping the infection restricted to the cervix. The interpretation of the histochemical and morphometric parameters can be useful in the diagnosis associated to HIV infection, contributing for clinical improvement and life expectancy.

Resumo Objetivos: comparar a porcentagem de fibras colágenas no corpo e colo uterino de mulheres autopsiadas com e sem a Síndrome da Imunodeficiência Adquirida (Aids). Métodos: foram selecionados 30 prontuários de mulheres autopsiadas no período de 1988 a 2013. Foram coletados 30 fragmentos do corpo uterino e 30 do colo uterino, dividido em dois grupos, 15 com Aids e 15 sem. A quantificação das fibras colágenas do corpo e colo uterino foi feita nas lâminas coradas por picrosirius, utilizando-se o sistema KS-300®. Resultados: a porcentagem de fibras colágenas foi menor no colo (U=336544; p=0,001) e maior no corpo uterino (U=308 726,5; p=0,004) no grupo com a retrovirose quando comparado ao grupo sem a doença. A porcentagem no grupo com Aids foi maior no colo uterino do que no corpo (t=0,4793; p=0,0031). Sendo o mesmo resultado encontrado para o grupo sem Aids (t=2.397; p=0,0637). Conclusões: um aumento da porcentagem de fibras colágenas no corpo uterino das mulheres com Aids indica uma resposta imune frente a infecção viral e revela uma falha em manter a infecção restrita ao colo. A interpretação dos parâmetros histoquímicos e morfométricos podem ser úteis no diagnóstico das condições associadas à infecção pelo HIV, contribuindo para a melhora clínica e expectativa de vida.

Epidemiological profile of patients co-infected with visceral leishmaniasis and HIV/AIDS in Northeast, Brazil

Abstract INTRODUCTION: Visceral leishmaniasis (VL) and human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) co-infection has been a research topic of interest worldwide. In Brazil, it has been observed that there is a relative underreporting and failure in the understanding and management of this important association. The aim of this study was to analyze epidemiological and clinical aspects of patients with VL with and without HIV/AIDS. METHODS: We conducted an observational and analytical study of patients with VL followed in a Reference Service in the State of Maranhão, Brazil from 2007-2013. RESULTS: In total 126 patients were enrolled, of which 61 (48.4%) were co-infected with HIV/AIDS. There were more males among those with HIV/AIDS (85.2%, P>0.05) or with VL only (81.5%, P>0.05). These findings significantly differed based on age group (P<0.003); the majority of patients were aged 31-40 years (41.0%) and 21-30 years (32.3%) among those with and without HIV/AIDS co-infection, respectively. The incidence of diarrhea and splenomegaly significantly differed between the two groups (P=0.0014 and P=0.019, respectively). The myelogram parasitic examination was used most frequently among those with HIV/AIDS (91.8%), followed by those with VL only (69.2%). VL recurrences and mortality were significantly higher in the HIV/AIDS co-infected patients (P<0.0001 and P=0.012, respectively). CONCLUSIONS: Patients with VL with or without HIV/AIDS co-infection were mostly adult men. Diarrhea was more frequent in HIV/AIDS co-infected patients, whereas splenomegaly was more common in patients with VL only. In the group of HIV/AIDS co-infected patients, there was a higher rate of VL recurrence and mortality.

Protein carbonyl content: a novel biomarker for aging in HIV/AIDS patients

Abstract Background: The major complications of “treated” Human Immunodeficiency Virus (HIV) infection are cardiovascular disease, malignancy, renal disease, liver disease, bone disease, and perhaps neurological complications, which are phenomena of the normal aging process occurring at an earlier age in the HIV-infected population. The present study is aimed to explore protein carbonyl content as a biomarker for detecting oxidative DNA damage induced ART toxicity and/or accelerated aging in HIV/AIDS patients. Objective: To investigate the potential of carbonyl content as a biomarker for detecting oxidative Deoxyribonucleic acid (DNA) damage induced Antiretroviral Theraphy (ART) toxicity and/or accelerated aging in HIV/AIDS patients. Methods: In this case–control study a total 600 subjects were included. All subjects were randomly selected and grouped as HIV-negative (control group) (n = 300), HIV-infected ART naive (n = 100), HIV-infected on first line ART (n = 100), and HIV-infected on second line ART (n = 100). Seronegative control subjects were age- and sex-matched with the ART naive patients and the two other groups. Carbonyl protein was determined by the method described in Levine et al. DNA damage marker 8-OH-dG was determined using 8-hydroxy-2-deoxy Guanosine StressXpress ELA Kit by StressMarq Biosciences. Results: Protein carbonyl content levels and oxidative DNA damage were significantly higher (p < 0.05) in HIV-infected patients on second line ART and HIV-infected patients on first line ART than ART naive patients and controls. In a linear regression analysis, increased protein carbonyl content was positively associated with increased DNA damage (OR: 0.356; 95% CI: 0.287–0.426) p < 0.05. Conclusions: Carbonyl content may has a role as a biomarker for detecting oxidative DNA damage induced ART toxicity and/or accelerated aging in HIV/AIDS patients. Larger studies are warranted to elucidate the role of carbonyl content as a biomarker for premature aging in HIV/AIDS patients.

Diferenças e similaridades entre mulheres que vivem e não vivem com HIV: aportes do estudo GENIH para a atenção à saúde sexual e reprodutiva / Diferencias y similitudes entre mujeres que viven y no viven con VIH: aportes del estudio GENIH para la atención a la salud sexual y reproductiva / Differences and similarities in women living and not living with HIV: contributions by the GENIH study to sexual and reproductive healthcare

Resumo: Estudo quantitativo foi conduzido no Município de São Paulo, Brasil, comparando contextos de vulnerabilidade social e o comportamento sexual e reprodutivo de uma amostra de 975 mulheres vivendo com HIV/aids (MVHA) e de 1.003 mulheres usuárias da rede de atenção básica à saúde. As MVHA são marcadas por situações de maior vulnerabilidade que, potencialmente, aumentaram o seu risco para a infecção pelo HIV e para eventos no campo reprodutivo. Comparando com mulheres usuárias da rede de atenção básica à saúde, as MVHA relataram em maiores proporções: uso de drogas, sexo em troca de dinheiro, exposição a parceiros íntimos violentos, dificuldades no acesso a serviços de prevenção e diagnóstico precoce, ocorrência de gestações não planejadas, aborto provocado e gravidez na adolescência. Parcela considerável das mulheres usuárias da rede de atenção básica à saúde compartilha as mesmas experiências, porém em menor magnitude. A identificação de contextos de vulnerabilidade e a integração de serviços de testagem anti-HIV e de saúde sexual e reprodutiva devem compor as linhas de cuidado às mulheres, tanto nos serviços especializados quanto nos de atenção básica.

Resumen: El estudio cuantitativo se realizó en el Municipio de São Paulo, Brasil, comparando contextos de vulnerabilidad social y el comportamiento sexual y reproductivo de una muestra de 975 mujeres, viviendo con VIH/SIDA (MVHA) y de 1.003 mujeres usuarias de la red de atención básica a la salud. Las MVHA se marcan por situaciones de mayor vulnerabilidad que, potencialmente, aumentaron su riesgo para la infección por el VIH y para eventos en el campo reproductivo. Comparando con mujeres usuarias de la red de atención básica a la salud, las MVHA informaron en mayor proporción de: consumo de drogas, sexo a cambio de dinero, exposición a parejas sentimentales violentas, dificultades en el acceso a servicios de prevención y diagnóstico precoz, ocurrencia de gestaciones no planeadas, aborto provocado y embarazo en la adolescencia. Una proporción considerable de las mujeres usuarias de la red de atención básica a la salud comparte las mismas experiencias, aunque en menor magnitud. La identificación de contextos de vulnerabilidad y la integración de servicios de test anti-VIH y de salud sexual y reproductiva deben formar parte de las líneas de cuidado a las mujeres, tanto en los servicios especializados, como en los de atención básica.

Abstract: This quantitative study in the city of São Paulo, Brazil, compared contexts of social vulnerability and sexual and reproductive behavior in a sample of 975 women living with HIV/AIDS (WLHIV) and 1,003 women not living with HIV, the latter recruited among users of the primary healthcare system. WLHIV experienced situations of greater vulnerability that potentially increased their risk of HIV infection and unplanned pregnancy and abortion. Compared to women users of the primary healthcare system, WLHIV reported higher rates of drug use, sex for money, exposure to intimate partner violence, difficulties in access to services for prevention and early diagnosis, unplanned pregnancies, induced abortion, and teenage pregnancy. A considerable number of the women users of the primary healthcare system shared these same experiences, but at lower rates. The identification of contexts of vulnerability and the integration of HIV testing services with sexual and reproductive health services should constitute lines of care for these women, both in specialized and primary care services.

Quality of life, socioeconomic and clinical factors, and physical exercise in persons living with HIV/AIDS / Qualidade de vida, fatores socioeconômicos e clínicos e prática de exercício físico em pessoas vivendo com HIV/aids

ABSTRACT OBJECTIVE To analyze whether socioeconomic and clinical aspects and the aspects of healthy life habits are associated with the quality of life of persons living with HIV/AIDS. METHODS This is a cross-sectional exploratory quantitative research, with 227 persons living with HIV/AIDS, treated at two hospitals of reference between April 2012 and June 2014. We used structured questionnaires to assess socioeconomic aspects (gender, age, education level, marital status, race, socioeconomic status, dependents on family income, employment relationship), clinical parameters (time of disease diagnosis, use and time of medication, CD4 T-cell count, and viral load), and practice of physical exercise. To assess quality of life, we used the Quality of Life questionnaire (HAT-QoL). For characterization of the socioeconomic and clinical data and domains of quality of life, we conducted a descriptive analysis (simple frequency, averages, and standard deviations). We applied linear regression, following a hierarchical model for each domain of quality of life. RESULTS The domains that presented lower averages for quality of life were financial concern, concern with confidentiality, general function, and satisfaction with life. We found associations with the variables of socioeconomic status and physical exercise, therapy, and physical exercise for the last two domains, consecutively. CONCLUSIONS The quality of life of persons living with HIV/AIDS shows losses, especially in the financial and confidentiality areas, followed by general function of the body and satisfaction with life, in which socioeconomic and clinical aspects and healthy living habits, such as the practice of physical exercise, are determining factors for this reality.

RESUMO OBJETIVO Analisar se aspectos socioeconômicos, clínicos e de hábitos de vida saudável estão associados à qualidade de vida em pessoas vivendo com HIV/aids. MÉTODOS Pesquisa quantitativa exploratória de corte transversal, com 227 pessoas vivendo com HIV/aids, atendidos em dois hospitais de referência entre os períodos de abril 2012 a junho de 2014. Foram utilizados questionários estruturados para avaliar aspectos socioeconômicos (sexo, idade, escolaridade, estado civil, cor de pele, status socioeconômico, dependentes da renda familiar, vínculo empregatício), parâmetros clínicos (tempo de diagnóstico da doença, uso e tempo de medicação, contagem de células TCD4 e carga viral) e prática de exercício físico. Para avaliar qualidade de vida, utilizou-se o questionário Quality of Life (HAT-QoL). Para caracterização dos dados socioeconômicos, clínicos e domínios da qualidade de vida, conduzimos análise descritiva (frequência simples, médias e desvios-padrão). Aplicamos regressão linear, seguindo um modelo hierárquico para cada domínio da qualidade de vida. RESULTADOS Os domínios que apresentaram menores médias para a qualidade de vida foram preocupação financeira, preocupação com sigilo, função geral e satisfação com a vida. Foram encontradas associações com as variáveis status socioeconômico e exercício físico; terapia; e exercício físico para os dois últimos domínios, consecutivamente. CONCLUSÕES A qualidade de vida de pessoas vivendo com HIV/aids apresentam prejuízos, principalmente nas questões financeiras e de sigilo, seguidos da função geral do corpo e satisfações com a vida, em que os aspectos socioeconômicos, clínicos e hábitos de vida saudável, como a prática de exercício físico, são fatores determinantes para essa realidade.

Audiological manifestations in HIV-positive adults

OBJECTIVE: To characterize the findings of behavioral hearing assessment in HIV-positive individuals who received and did not receive antiretroviral treatment. METHODS: This research was a cross-sectional study. The participants were 45 HIV-positive individuals (18 not exposed and 27 exposed to antiretroviral treatment) and 30 control-group individuals. All subjects completed an audiological evaluation through pure-tone audiometry, speech audiometry, and high-frequency audiometry. RESULTS: The hearing thresholds obtained by pure-tone audiometry were different between groups. The group that had received antiretroviral treatment had higher thresholds for the frequencies ranging from 250 to 3000 Hz compared with the control group and the group not exposed to treatment. In the range of frequencies from 4000 through 8000 Hz, the HIV-positive groups presented with higher thresholds than did the control group. The hearing thresholds determined by high-frequency audiometry were different between groups, with higher thresholds in the HIV-positive groups. CONCLUSION: HIV-positive individuals presented poorer results in pure-tone and high-frequency audiometry, suggesting impairment of the peripheral auditory pathway. Individuals who received antiretroviral treatment presented poorer results on both tests compared with individuals not exposed to antiretroviral treatment. .

Complicaciones en los tratamientos odontológicos en los niños vih (+) con diagnóstico hematológico de anemia / The dental treatment complications in hiv (+) children with hematological diagnosis of anemia

Determinar las complicaciones en los tratamientos odontológicos en los niños VIH (+) con diagnóstico hematológico. Estudio retrospectivo, analítico y transversal de la relación entre niños VIH (+) con anemia y bajo terapia antirretroviral que asistieron al CAPEI/UCV en el período 2000-2010, y las complicaciones ocurridas en los tratamientos odontológicos. En relación a las complicaciones en todos los pacientes, se pudo observar en un 20% (28/137) infecciones y sangrado, mientras que el 80% (109/137) no presentó. El tratamiento odontológico llevado a cabo con las menores complicaciones y seguridad en estos niños y niñas con VIH, sumado a los procesos infamatorios e infecciones que inciden en la respuesta inmunológica, nos lleva a establecer como imperativo socio moral que la atención en salud bucal forme parte de los equipos interdisciplinarios dedicados al tratamiento de este tipo de paciente...

To determine the dental treatment complications in HIV (+) children with hematological diagnosis of anemia. A retrospective, analytical and cross-sectional study of the relationship between HIV (+) children with anemia and on antiretroviral therapy attending the CAPEI / UCV in 2000-2010, and complications occurred in dental treatments. In relation to complications in all patients, it was observed that 20% (28/137) had infections and sacred, while 80% (109/137) did not. The dental treatment carried out with minor complications and safety in these children with HIV, coupled with libelous processes and infections that affect the immune response, leads us to establish as a moral imperative partner in oral health care part of interdisciplinary teams dedicated to the treatment of this type of patient...

Weight and height of people living with HIV/AIDS attended by the Brazilian National Health System / Peso e altura de pessoas vivendo com HIV/aids em atendimento no Sistema Unico de Saude

The nutritional status of people living with HIV/AIDS (PLWHA) is related to morbidity and mortality and its monitoring is important in the maintenance of the health status. This is a cross-sectional study carried out in Brazilian National Health System in the Municipality of São Paulo. It describes anthropometrical characteristics: weight and height; indices of weight for height (W/H), height for age (H/A), body mass index for age (BMI/A) and Z score for height and weight. The study includes 772 participants from all ages: children, adolescents, adults and elderly. The graphical analysis shows that in under-5s and in the 5 to 19 years old group, the W/H, the H/A and the BMI/A curves are similar to the reference population with an exception in the H/A for 5 to 19 years old group which is left-shifted (mean Z = -0.66). In the case of adults, graphics for the study population show median weight apparently lower than in the reference population for most age groups in the case of men, and when age is greater in women. The proportion of people over 20 years old with AIDS on anti-retroviral therapy is lower when coinfection is present (p < 0.001). The findings of the study showed that, for children and adolescents with HIV/AIDS, the average weight and height are lower than the values for non infected population. For adults and elderly, the weight average is lower than the reference population with a worsening among coinfected patients. This underscores the need to direct more effort in nutritional actions thus helping enhance the health status of this group.

O estado nutricional de pessoas que vivem com HIV/aids (PVHA) está relacionado a morbidade e mortalidade e seu monitoramento auxilia na manutenção do estado de saúde. Este é um estudo de corte transversal realizado no Sistema Único de Saúde no Município de São Paulo. O presente estudo descreve características antropométricas: peso e altura; índices de peso para estatura (P/E), estatura para idade (E/I), índice de massa corporal para idade (IMC/I) e escore Z para peso e estatura. Inclui 772 participantes entre crianças, adolescentes, adultos e idosos. A análise gráfica mostra que, em crianças menores de 5 anos e no grupo de 5 a 19 anos, o P/E, a E/I e as curvas de IMC/I são semelhantes às da população de referência, com uma exceção onde a curva de E/I para o grupo de 5 a 19 anos é deslocada para a esquerda (média Z = -0,66). No caso dos adultos, observou-se mediana de peso aparentemente menor do que a população de referência para a maioria dos grupos de idade entre os homens e para as mulheres em idade mais avançada. A proporção de pessoas maiores de 20 anos com aids usando terapia antirretroviral é menor na presença de coinfecção (p < 0,001). As conclusões do estudo mostraram que crianças e adolescentes com HIV/aids apresentam estatura e peso médio inferior à população não infectada. Entre os adultos e idosos, o peso médio é menor que o da população de referência, principalmente na presença de coinfecção. Enfatiza-se a necessidade de reforçar ações nutricionais, contribuindo, assim, para melhoria do estado de saúde desse grupo.

Association between muscle strength and the cardiopulmonary status of individuals living with HIV/AIDS

OBJECTIVE: The purpose of this study was to compare aerobic function [anaerobic threshold (%VO2-AT), respiratory compensation point (%VO2-RCP) and peak oxygen uptake (VO2peak)] between physically active patients with HIV/AIDS and matched controls and to examine associations between disease status, poor muscle strength, depression (as estimated by the profile of mood states questionnaire) and the aerobic performance of patients. METHODS: Progressive treadmill test data for %VO2-AT (V-slope method), RCP and (VO2peak) were compared between 39 male patients with HIV/AIDS (age 40.6±1.4 years) and 28 male controls (age 44.4±2.1 years) drawn from the same community and matched for habitual physical activity. Within-patient data were also examined in relation to CD4+ counts (nadir and current data) and peak isokinetic knee torque. RESULTS: AT, RCP and (VO2peak) values were generally similar for patients and controls.Within the patient sample, binary classification suggested that AT, RCP and (VO2peak) values were not associated with either the nadir or current CD4+ count, but treadmill test variables were positively associated with peak isokinetic knee torque. CONCLUSION: The aerobic performance of physically active patients with HIV/AIDS is generally well conserved. Nevertheless, poor muscle strength is observed in some HIV/AIDS patients, which is associated with lower anaerobic power and (VO2peak), suggesting the possibility of enhancing the aerobic performance of patients with weak muscles through appropriate muscle-strengthening activities.

Malnutrición en niños colombianos con infección por VIH/SIDA / Malnutrition in Colombian children with HIV/AIDS infection

Introducción: La desnutrición (DNT) es una de las complicaciones más tempranas que se presenta en niños con infección por VIH/SIDA, asociada a su morbimortalidad. Igualmente como consecuencia de la terapia antriretroviral y otros medicamentos utilizados, se han encontrado problemas de resistencia a la insulina y obesidad. Objetivo: Determinar la prevalencia de malnutrición (MNT) en niños con infección por VIH/SIDA por carga viral de la Clínica de VIH/SIDA del Hospital Universitario del Valle de Cali, Colombia (HUV) y su posible asociación con algunos factores de riesgo. Metodología: Estudio descriptivo, observacional de corte transversal, con análisis de casos y controles, a quienes se les tomaron datos como carga viral, %CD4, peso y talla. Se categorizó la carga viral (copias/ml) en: <400, ≥400-<300000, ≥30000-<1 millón y ≥1 millón; y el %CD4 en: <15%, ≥15%-<25% y ≥25%. Se consideró DNT global (déficit P/E≥10%), DNT crónica (déficit T/E≥5%), DNT aguda (déficit P/T≥10%) y sobrepeso (exceso P/T≥10%). Resultados: Fueron incluidos 111 niños entre 0 meses y 15 años de edad, con predominio del género masculino (51,3%), con modo de transmisión vertical en 91,8%. El 58.5% tenían entre ≥400-<300000 copias/ml de carga viral; y el 59% presentaron %CD4 ≥25%. La valoración nutricional evidenció DNT global en 64%, DNT aguda en 58%, DNT crónica en 22% y sobrepeso en 18%. Hubo riesgo de 1.7, 1.5 y 2.0 veces más de presentar DNT global, aguda y crónica, respectivamente, si la carga viral era ≥400 copias/ml. Conclusión: En niños con infección por VIH/SIDA por carga viral de la Clínica Pediátrica de VIH/SIDA del HUV de Cali, Colombia, la prevalencia de MNT fue superior al 18%, con una relación positiva superior a 1.5 veces entre carga viral y los diferentes tipos de DNT.

Introduction: Undernutrition (UNT) is a complication that occurs earlier in children with HIV/AIDS associated morbidity and mortality. Also as a result of anti-retroviral therapies and other drugs used, have encountered problems of insulin resistance and obesity. Objective: To determine the prevalence of malnutrition (MNT) in children diagnosed with HIV/AIDS by viral load in the Pediatric Clinic HIV/AIDS at the Hospital Universitario del Valle in Cali, Colombia (HUV) and its possible association with certain risk factors. Methodology: A descriptive cross-sectional study, with case-control analysis, whose data were taken as viral load, CD4%, weight and height. Were categorized viral load (copies / ml): <400, ≥ 400 - <300000, ≥ 30000 - <1 million and ≥ 1 million, and the %CD4 <15%, ≥ 15% - <25% ≥ 25%. UNT is considered global (low W/A≥10%), chronic (low H/A≥5%), acute (low W/H≥10%) and overweight (excess W/H≥10%). Results: We included 111 children from 0 months to 15 years old with male predominance (51.3%), mode of transmission in 91.8%. 58.5% were aged ≥ 400 - <300,000 copies/ml viral load, and 59% had CD4% ≥25%. Nutritional assessment showed 64% global UNT, 58% acute UNT, 22% chronic UNT and 18% overweight. Risk was 1.7, 1.5 and 2.0 times the present global, acute and chronic UNT, respectively, if the viral load was ≥ 400 copies / ml. Conclusion: In children diagnosed with HIV/AIDS by viral load of Pediatric Clinic HIV/AIDS at the HUV in Cali, Colombia, the prevalence of MNT was higher than 18%, with a positive relationship more than 1.5 times between viral load and the different types of UNT.

Estado nutricional, clínico e padrão alimentar de pessoas vivendo com HIV/Aids em assistência ambulatorial no município de São Paulo / Nutritional and clinical status, and dietary patterns of people living with HIV/AIDS in ambulatory care in Sao Paulo, Brazil

INTRODUÇÃO: Atualmente, a abordagem nutricional desempenha papel essencial no tratamento de pessoas que vivem com HIV/aids, particularmente no caso de alterações metabólicas pelo uso da terapia antirretroviral (TARV) que podem estar associadas ao maior risco de doenças cardiovasculares (DCV). OBJETIVO: Caracterizar o estado nutricional, clínico e a qualidade da dieta de pessoas que vivem com HIV/aids. METODOLOGIA: Trata-se de um estudo transversal envolvendo pessoas que vivem com HIV/aids em atendimento na rede de serviços especializados no município de São Paulo. Os usuários desta rede, em uso ou não de TARV, foram recrutados no período de dezembro de 2004 a maio de 2006, durante consultas de rotina. Foram coletados dados sociodemográficos, clínicos, bioquímicos, antropométricos e dietéticos. A qualidade da dieta foi avaliada segundo escores de padrão de consumo predominantemente "não protetor" e "protetor" para DCV. RESULTADOS: A amostra foi constituída por 238 pacientes em TARV e 76 sem TARV. A média dos níveis de colesterol total, triglicérides e glicemia foram maiores no grupo TARV (p < 0,001). A maior parte dos participantes do estudo, com e sem TARV, apresentava-se eutrófica, com média de índice de massa corporal 24,4 (± 4,3) e 24,3 (± 3,5) kg/m², respectivamente. A relação cintura-quadril foi maior entre homens em TARV que entre aqueles sem TARV (0,90 ± 0,06 versus 0,87 ± 0,05) (p < 0,001). O grupo em TARV apresentou média de escores indicativa de maior consumo de alimentos "não protetores" para DCV (p = 0,001). CONCLUSÃO: Foram evidenciadas condições nutricionais e metabólicas indesejáveis entre aqueles em TARV, predisponentes ao risco de DCV. É apontada a necessidade de direcionamento das intervenções em saúde a pessoas que vivem com HIV/aids, para o controle dos fatores associados a essas doenças antes do desfecho final.

INTRODUCTION: Nutrition currently plays a key role in the treatment of people living with HIV/AIDS (PLHA), especially in the case of metabolic alterations due to highly active antiretroviral therapy (HAART), which could be related to cardiovascular diseases (CD). OBJECTIVE: to describe the nutritional and clinical status, and the quality of diet of PLHA. METHODS: It is a cross-sectional study involving a network of ambulatory care facilities for PLHA in the city of São Paulo, Brazil. Patients, in use of HAART or not, were selected from December 2004 to may 2006, through routine clinic visits. We collected: socio-demographic, clinical, biochemical, anthropometric measures and dietary data. Diet quality was evaluated according to a "protecting" or "non-protecting" pattern of consumption scores for CD. RESULTS: The sample had 238 patients on HAART and 76 without treatment. Mean serum levels of total cholesterol, triglycerides and glucose were higher in the HAART group (p < 0.001). The majority of patients of both the treated and untreated group were eutrophic with a mean body mass index (BMI) of 24.4 (± 4.3) kg/m² and 24.3 (± 3.5), respectively. The waist-hip ratio was higher among men on HAART (0.90 ± 0.06 versus 0.87±0.05) (p < 0.001). The HAART group showed a mean food pattern score indicating a higher consumption of "non-protecting" foods for CD (p = 0.001). CONCLUSION: The results showed undesired nutritional and metabolic conditions among patients on HAART associated with CD. It is necessary to manage health intervention programs for PLHA in order to control cardiovascular risk factors before final outcomes.

Sarcoma de Kaposi relacionado à síndrome da imunodeficiência adquirida: características do comprometimento hepático na tomografia computadorizada e na ressonância magnética / Kaposi sarcoma related to acquired immunodeficiency syndrome: hepatic findings on computed tomography and magnetic resonance imaging", "_i": "en

Sarcoma de Kaposi é uma neoplasia associada a condições de imunossupressão que acomete os vasos linfáticos e sanguíneos. É a neoplasia intra-hepática mais comum na síndrome da imunodeficiência adquirida. A tomografia computadorizada e a ressonância magnética revelam múltiplos pequenos nódulos, proeminência e realce dos planos periportais, devido à presença de tecido neoplásico. Os autores descrevem um caso de paciente masculino, de 47 anos de idade, com síndrome da imunodeficiência adquirida e sarcoma de Kaposi disseminado.

Kaposi sarcoma is a neoplasm associated with immunosuppressive conditions, and involving blood and lymphatic vessels. It is the most frequent intrahepatic neoplasm in patients with acquired immunodeficiency syndrome. Computed tomography and magnetic resonance imaging demonstrate multiple small nodules, prominence and contrast-enhancement of periportal branches due to the presence of the neoplastic tissue. The authors report a case of a 47-year-old male patient with acquired immunodeficiency syndrome presenting disseminated Kaposi sarcoma.

Manifestações gastrointestinais relacionadas à síndrome da imunodeficiência adquirida: do diagnóstico / Gastrointestinal manifestations regarding the acquired immunodeficiency syndrome: from diagnosis to treatment

Os sinais e sintomas relacionados ao trato gastrointestinal em decorrência da síndrome da imunodeficiência adquirida (SIDA) são muito freqüentes. Por essa razão realizou-se uma revisão através do PubMed, para abordar os principais achados clínicos, diagnósticos e opções terapêuticas que orientem os médicos internistas frente a essas situações.

Potenciais evocados auditivos de longa latência em adultos com HIV/Aids / Long latency auditory evoked potentials in adults with HIV/Aids

TEMA: potenciais evocados auditivos de longa latência. OBJETIVO: caracterizar os potenciais evocados auditivos de longa latência (Peall) de indivíduos com HIV/Aids comparando com os obtidos no grupo controle. MÉTODO: a casuística foi composta por 21 indivíduos com HIV/Aids pertencentes ao grupo pesquisa (14 do gênero masculino e sete do gênero feminino) com idade entre 31 e 48 anos e 21 indivíduos saudáveis pertencentes ao grupo controle (cinco do gênero masculino e 16 do gênero feminino) com idade entre 19 e 36 anos. Foram analisados os valores de latência e amplitude da onda P300, latência das ondas N1 e P2 e amplitude N1-P2. Os eletrodos foram colocados nas posições A1, A2, Cz e Fpz. RESULTADOS: no P300 observou-se que o grupo com HIV/Aids apresentou maiores valores de latência (p-valor = 0,010) e menores de amplitude (p-valor = 0,021) quando comparados com o grupo controle. Na análise do complexo N1-P2, ao comparar os grupos, verificou-se que o grupo pesquisa apresentou maiores valores de latência tanto para a onda N1 (p-valor = 0,035) como para a onda P2, porém esta última sem diferença estatisticamente significante. Com relação à análise da amplitude N1-P2, verificou-se que o grupo controle apresentou maiores valores, sendo esta diferença estatisticamente significante quando comparada ao grupo pesquisa. CONCLUSÃO: os achados do presente estudo mostraram que indivíduos com HIV/Aids apresentam alterações nos Peall, sugerindo comprometimento nas áreas corticais do sistema auditivo e mostrando a importância destes testes na avaliação audiológica de indivíduos com HIV/Aids.

BACKGROUND: Long Latency Auditory Evoked Potentials. AIM: to characterize the Long Latency Auditory Evoked Potentials (LLAEP) in individuals with HIV/AIDS in comparison to a control group. METHOD: the research sample was composed by 21 individuals with HIV/AIDS - research group (14 male and 7 female), with ages ranging from 31 to 48 years, and 21 healthy individuals - control group (5 male and 16 female), with ages ranging from 19 to 36 years. The latency and amplitude values of the P300 wave were analyzed; latency of N1 and P2 waves, and amplitude N1-P2. The electrodes were placed on the following positions: A1, A2, Cz and Fpz. RESULTS: the T-student test was used to analyze the results and the adopted significance level was of 5 percent. In the analyzes of P300 it was observed that the group with HIV/AIDS presented greater latency values (p-value = 0,010) and lower amplitude values (p-value = 0,021) when compared to the control group. The analysis of the N1-P2 complex revealed that the research group presented higher latency values for both, N1 wave (p-value = 0,035) and P2 wave, however for this last one, there was no significant statistical difference when compared to the control group. Concerning the amplitude analysis of the N1-P2 complex, it was verified that the control group presented significantly higher values when compared to the research group. CONCLUSION: the findings of this study indicates that individuals with HIV/AIDS present alterations in the Long Latency Auditory Evoked Potentials (higher latencies and lower amplitudes of N1, P2 and P300 waves), suggesting a disorder in the cortical regions of the auditory pathway, and therefore stressing the importance of such tests in the evaluation of these individuals.

Dislipidemia associada à terapia anti-retroviral em pacientes com AIDS / Dyslipidemia associated with antiretroviral therapy in AIDS patients

A disponibilidade da terapia anti-retroviral tem resultado em um enorme declínio nas taxas de morbidade e mortalidade dos pacientes infectados pelo vírus da imunodeficiência humana. entretanto, tal terapia tem sido associada a efeitos metabólicos adversos, como a dislipidemia; sendo assim, indivíduos com doença arterial coronariana devem ser identificados e tratados. Este artigo faz uma revisão das anormalidades dos lipídios e das lipoproteínas associadas ao uso dos inibidores de proteases, sobre o possível mecanismo da dislipidemia associada a estes inibidores e usa o protocolo do programa de educação para tratamento do colesterol em adultos(National Cholesterol Education Program Adult Treatment Panel III Guidelines) para o acompanhamento do paciente com dislipidemia.
