Aerobic capacity and health-related quality of life in adults HIV-infected patients with and without lipodystrophy

Abstract Introduction HIV infection and its therapy which can affect their aerobic capacity and health-related quality of life of patients. Objective We conducted a cross-sectional study to determine if aerobic capacity and health related quality of life was decreased in HIV-infected patients receiving highly active antiretroviral therapy and comparing patients with and without lipodystrophy. Research design and methods HIV-infected patients older than 18 years, and in current use of highly active antiretroviral therapy drugs, were evaluated for blood count, fasting total cholesterol, high density lipoprotein, triglycerides, glucose, HIV viral load and CD4/CD8 counts, body composition, peak oxygen consumption (peak VO2) and metabolic equivalent. Health related quality of life was assessed by using Short Form-36 (SF-36). Statistical analysis was carried out using SPSS version 20.0. Results A total of 63 patients with mean age of 43.1 ± 6.4 years were evaluated, of these 34 (54%) had lipodystrophy. The average peak VO2 (31.4 ± 7.6 mL kg−1 min−1) was significantly lower (p < 0.01) than expected values (37.9 ± 5.6 mL kg−1 min−1) according to the characteristics of the patients. The lipodystrophy group presented with a significant difference in muscle mass, body fat, peak VO2 and metabolic equivalent and in functional capacity domains of SF-36. Conclusion Aerobic capacity values were reduced in HIV-infected patients under highly active antiretroviral therapy when compared to predicted values. Lipodystrophy was associated with reduced aerobic capacity and higher frequency of metabolic syndrome. Lifestyle modification should be a priority in the management of chronic HIV disease.

Body changes: antiretroviral therapy and lipodystrophy syndrome in people living with HIV/aids / Alterações corporais: terapia antirretroviral e síndrome da lipodistrofia em pessoas vivendo com HIV/AIDS / Alteraciones corporales: terapia antirretroviral y síndrome de la lipodistrofia en personas que viven con VIH/SIDA

OBJECTIVE: to identify the different types of morphological alterations from lipodystrophy syndrome (LS) in outpatients and relate them to the therapeutic regimen used. METHOD: a cross-sectional study which recruited 60 patients with HIV and LS and 79 without LS, who consented to interview and data collection from their medical notes. RESULTS: the region most affected by lipoatrophy was the face; by lipohypertrophy, the abdomen, and by the mixed form, the alterations to the abdomen, face, and upper and lower limbs. CONCLUSION: among the therapeutic regimens, that comprised of zidovudine, lamivudine and efavirenz seemed to protect against LS. Nursing can act in the early identification of the changes, as well as providing guidance and support for patients affected by the changes in their body image.

OBJETIVO: identificar os diferentes tipos de alterações morfológicas da síndrome da lipodistrofia (SL) em pacientes dos atendimentos ambulatoriais e relacioná-las ao esquema terapêutico utilizado. MÉTODO: estudo transversal, para o qual foram recrutados 60 pacientes com HIV e SL e 79 sem a SL, que consentiram entrevista e coleta de dados em prontuário. RESULTADOS: a região mais acometida pela lipoatrofia foi a face; pela lipo-hipertrofia o abdome e pela forma mista as alterações em abdome, face, membros superiores e inferiores. CONCLUSÃO: dentre os esquemas terapêuticos, o composto pela zidovudina, lamivudina e efavirenz pareceu proteger contra a SL. A enfermagem pode atuar na identificação precoce das alterações, além de fornecer orientações e apoio aos pacientes acometidos pelas mudanças na imagem corporal.

What should we know about metabolic syndrome and lipodystrophy in AIDS? / O que devemos saber sobre síndrome metabólica e lipodistrofia na AIDS?

OBJECTIVE: Prevalence of chronic complications of HIV infection is increasing and early recognition and treatment of the components of metabolic syndrome (MS) are essential to prevent cardiovascular and metabolic complications. Considering this, we performed a cross-sectional study on the prevalence and risk-factors for MS among HIV-infected subjects. METHODS: A total of 819 patients followed at a large outpatient HIV unit were assessed by an interviewer-administered questionnaire that recorded several demographic, epidemiologic, clinical, laboratory, and social variables. Lipodystrophy diagnosis relied on agreement between patient's self-report and physician's observation of altered body-fat deposits. The presence of three or more of the following characteristics identified MS: increased waist circumference, hypertriglyceridemia, low HDL cholesterol level, hypertension, and hyperglycemia. We used logistic regression analyses to study variables independently associated with MS. RESULTS: The prevalence of MS was 20.6 percent and that of lipodystrophy was 38.5 percent. 61 (36.1 percent) out of 169 patients with MS had also lipodystrophy. Patients with metabolic syndrome were significantly more likely to be older (OR = 1.08), had higher CD4 counts (OR = 1.001), had an increased body mass index (OR = 1.27) and had longer exposure to antiretroviral therapy (OR = 1.01) than those without metabolic syndrome. CONCLUSION: Both traditional risk factors for cardiovascular disease and factors associated with HIV infection itself, such as an increased CD4 cell count and a longer exposure to antiretroviral therapy, seem to be associated with metabolic syndrome in the present study population.

OBJETIVO: A prevalência de complicações crônicas da infecção HIV está aumentando, e o reconhecimento precoce e o tratamento dos componentes da síndrome metabólica (SM) são essenciais para a prevenção de complicações cardiovasculares e metabólicas. Considerando isso, realizamos um estudo transversal sobre prevalência e fatores de risco para SM em indivíduos HIV+. MÉTODOS: Um total de 819 pacientes acompanhados em um ambulatório de HIV foi avaliado por um entrevistador que registrou em questionário dados demográficos, epidemiológicos, clínicos, laboratoriais e variáveis sociais. O diagnóstico de lipodistrofia baseou-se na concordância entre autorrelato do paciente e observação do médico das alterações de gordura corporal. A SM foi identificada pela presença de três ou mais das seguintes características: circunferência abdominal aumentada, hipertrigliceridemia, colesterol HDL baixo, hipertensão e hiperglicemia. Análises de regressão logística foram utilizadas para identificar variáveis associadas à SM. RESULTADOS: A prevalência de SM foi 20,6 por cento e de lipodistrofia foi 38,5 por cento. Entre os 169 pacientes com SM, 61 (36,1 por cento) apresentavam lipodistrofia. Os pacientes com síndrome metabólica tinham, significativamente, maior probabilidade de ser mais velhos (OR = 1,08), ter maior contagem de CD4 (OR = 1,001), ter maior índice de massa corporal (OR = 1,27) e ter maior tempo de exposição à terapia antirretroviral (OR = 1,01). CONCLUSÃO: Tanto fatores de risco tradicionais para doença cardiovascular quanto fatores associados à infecção HIV, como aumento da contagem de CD4 e maior exposição à terapia antirretroviral, parecem estar associados à SM na população estudada.

Antiretroviral therapy-associated dyslipidemia in patients from a reference center in Brazil

The aim of this study was to determine the impact of antiretroviral therapy on the lipid profile of human immunodeficiency virus (HIV) patients before and after the initiation of highly active antiretroviral therapy (HAART). This was a cross-sectional analysis of patients receiving HAART at a reference center in Belo Horizonte, Brazil, on the basis of medical records from 2002 to 2006. Patients were included if they had at least one lipid test or a clinical or laboratory diagnosis of dyslipidemia/lipodystrophy. Among the 692 patients, 620 met the eligibility criteria. The majority were males (66.5 percent), middle age (average 39 years), had a low educational level (60.4 percent), and low income (51.0 percent). HAART duration ranged from 11 days to 4.6 years, with a mean of 28.6 months (SD = ± 470.19 days). The prevalence of dyslipidemia/lipodystrophy nearly tripled (11.3 percent pre- and 32.4 percent post-HAART). Dyslipidemia was associated with older age (P = 0.007), nucleoside reverse transcriptase inhibitor (NRTI) + protease inhibitor (PI) regimens (P = 0.04), NRTI + non-NRTI (NNRTI) regimens (P = 0.026), the use of stavudine (d4T) in any regimen (P = 0.002) or in NRTI-based regimens (P = 0.006), and longer exposure to HAART (P < 0.000). In addition, there was no correlation between dyslipidemia and gender (P = 0.084). Only 2.0 percent of the patients received treatment for dyslipidemia during the trial. These results show a need for continuous monitoring of patients under antiretroviral therapy, particularly those using NRTI-based regimens, especially when combined with d4T and PIs. Secondly, interventions should be developed to correct metabolic changes.

Adverse effects of antiretroviral treatment.

BACKGROUND: The introduction of highly active antiretroviral therapy (HAART) has led to significant reduction in acquired immune deficiency syndrome (AIDS)-related morbidity and mortality. Adverse drug reactions (ADRs) to antiretroviral treatment (ART) are however, major obstacles in its success. AIMS: We sought to study the adverse effects of ART in a resource-restricted setting in India. METHODS: Hundred patients on ART were studied prospectively over a period of two years. All patients were asked to visit the clinic if they developed any symptoms or on a monthly basis. They were screened clinically and investigated suitably for any ADRs. RESULT: Out of the 100 patients, ten patients did not come for follow-up; only 90 cases were available for evaluation. ADRs were observed in 64 cases (71.1%) - the maximal frequency of ADRs was seen with zidovudine (AZT) (50%) followed by stavudine (d4T) (47.9%), efavirenz (EFV) (45.4%) and finally, Nevirapine (NVP) (18.4%). Most common ADRs were cutaneous (44.4%) followed by hematological (32.2%), neurological (31.1%), metabolic (22.2%) and gastrointestinal (20%). Most common cutaneous ADRs observed were nail hyperpigmentation (14.4%) and rash (13.3%). Immune reconstitution inflammatory syndrome (IRIS) was observed as a paradoxical reaction to ART in 20 (22.2%) cases. CONCLUSION: To optimize adherence and thus, efficacy of ART, clinicians must focus on preventing adverse effects whenever possible, and distinguish those that are self-limited from those that are potentially serious.

Lipodystrophy syndrome associated with antiretroviral therapy in HIV patients: considerations for psychosocial aspects: [review] / Síndrome de la lipodistrofia asociado con la terapia antiretroviral en pacientes con VIH: consideraciones para los aspectos psicosociales: [revisión] / Sindrome da lipodistrofia associada com a terapia anti-retroviral em portadores do HIV: considerações para os aspectos psicossociais: [revisão]

Several side effects have been strongly associated with antiretroviral therapy in HIV patients. Among them, the lipodystrophy syndrome which presents alterations in body shape with central adipose hypertrophy and peripheral lipoatrophy, reported by patients as a visible marker identifying them as HIV patients. This manuscript presents an analysis of current literature regarding the psychosocial aspects of HIV patients with lipodystrophy associated with antiretroviral therapy. The results show that the alterations in body shape can be disturbing in terms of psychosocial well being, affecting quality of life and increasing the stigma associated with the disease, with consequent disturbances in social relations. This analysis provides a preliminary review of the psychosocial aspects of lipodystrophy and further studies are needed for a better understanding of this complex syndrome, which could provide new information to be used in nursing care for HIV patients affected by this problem.

Varios efectos secundarios han sido fuertemente asociados con la terapia antiretroviral en pacientes con HIV. Entre ellos, el síndrome de la lipodistrofia se presenta con alteraciones en la forma del cuerpo con hipertrofia adiposa central y lipoatrofia periférica, las cuales son reportadas por pacientes como marcas visibles que los identifica como pacientes con VIH. En este manuscrito, presentamos un análisis de literatura actual con respecto a los aspectos psicosociales de pacientes con VIH presentándose con lipodistrofia asociado con la terapia antiretroviral. Los resultados demuestran que las alteraciones de la forma del cuerpo pueden ser inquietantes en lo que se refiere al bienestar psicosocial, afectando la calidad de vida y aumentando el estigma asociado con la enfermedad, con las consiguientes dificultades en las relaciones sociales. Este análisis provee un repaso preliminar de los aspectos psicosociales de la lipodistrofia; sin embargo, otros estudios son necesarios para entender mejor este complejo síndrome, proveyendo nueva información para ser utilizada en el cuidado de enfermería para pacientes con VIH que están afectados por este problema.

Diversos efeitos colaterais têm sido associados à terapia anti-retroviral em portadores da infecção pelo HIV, dentre esses, a síndrome da lipodistrofia apresentando hiperlipidemia e alterações na forma do corpo, com hipertrofia adiposa central e lipoatrofia periférica, relatada pelos pacientes como um visível marcador para a identificação de portadores da infecção pelo HIV. Este estudo consiste em análise da produção científica sobre aspectos psicossociais em portadores da infecção pelo HIV que apresentam lipodistrofia associada à utilização da terapia anti-retroviral. Os resultados mostram que alterações corporais podem ser suficientemente perturbadoras para o bem-estar psicossocial, afetando a qualidade de vida e aumentando o estigma da doença, ocasionando perturbações nas relações sociais. Esta revisão possibilita uma análise preliminar dos aspectos psicossocias da lipodistrofia; entretanto, outros estudos são necessários para o melhor entendimento desta complexa síndrome, trazendo novas informações a serem utilizadas no cuidado de enfermagem a portadores da infecção pelo HIV afetados por este problema.

Lipodystrophy and dyslipidemia in human immunodeficiency virus-infected Thai patients receiving antiretroviral therapy.

BACKGROUND: Lipodystrophy and dyslipidemia are increasing problems in HIV-infected patients receiving antiretroviral therapy (ART). OBJECTIVE: Determine the prevalence and predicting factors for lipodystrophy and dyslipidemia in these patients. MATERIAL AND METHOD: A cross-sectional study was performed on HIV-infected patients receiving ART in January 2006. Clinical assessment for lipodystrophy and blood tests for lipid profile were obtained. RESULTS: There were 56 patients with a mean age of 42.3 years and 71.4% were male. Lipodystrophy was detected in 66.1%. Baseline characteristics between patients with and without lipodystrophy were similar except for age, history of receiving d4T and undetectable HIV-RNA (p < 0. 05). There was a high prevalence of dyslipidemia (53.6%). By logistic regression, undetectable HIV-RNA (odds ratio (OR) 6.4, p = 0.016) and receiving d4T (OR 7.4, p = 0.022) are predicting factors for lipodystrophy. CONCLUSION: Lipodystrophy and dyslipidemia in HIV-infected Thai patients receiving ART are common. Clinical monitoring for these abnormalities during ART is highly recommended.
