Self-reported HIV/HAART-associated Lipodystrophy and Modifiable Risk Factors for Cardiovascular Disease

Abstract Background Patient self-report is the most common diagnostic tool in the literature to detect HIV/HAART-associated lipodystrophy. However, data on the association of cardiovascular risk factors with HIV/HAART-associated lipodystrophy assessed by self-report are still missing. Objectives To determine the prevalence of self-reported HIV/HAART-associated lipodystrophy and to identify independent associations between traditional modifiable cardiovascular risk factors and self-reported lipodystrophy. Methods We conducted a retrospective observational study at an outpatient infectious disease clinic in the Central-West of Brazil to identify the association between traditional modifiable cardiovascular risk factors and self-reported lipodystrophy. Sedentary lifestyle, smoking status, family history of cardiovascular disease, hypertension, diabetes, dyslipidemia, increased waist circumference and overweight were the cardiovascular risk factors assessed. Self-reported HIV/HART-associated lipodystrophy was categorized as: mild (noticeable by patients' close inspection), moderate (easily noticeable by patient and physician) or severe (readily noticeable by a casual observer). Prevalence ratio (PR) and 95% confidence interval (CI95%) were calculated. Multivariate Poisson's regression was used to analyze factors associated to HIV/HAART-associated lipodystrophy assessed by self-report considering a significance level of 5%. Results A total of 183 patients were included, with a mean age of 39.3±10.9 years. Most of the sample were male (77.6%), non-white (50.8%) and single (53.0%). The overall prevalence of HIV/HAART-associated lipodystrophy was 52.5% (95% CI 44.96 - 59.88). Severe lipodystrophy was observed in more than half patients (55.2%). No traditional modifiable cardiovascular risk factor was independently associated with lipodystrophy. Female sex (PR 1.49; 95% CI 1.15 - 1.95; p =0.003), time of HIV infection diagnosis of 1-3 years (PR 1.83; 95% CI 1.09 - 3.08; p =0.002) and a positive family history of CVD (PR 1.62; 95% CI 1.11 - 2.36; p <0.001) were independently associated with lipodystrophy. Conclusion HIV/HAART-associated lipodystrophy assessed by patient self-report was not associated with traditional modifiable cardiovascular risk factors.

Síndrome lipodistrófica do HIV e seus fatores associados: um estudo em um hospital universitário / Lipodystrophic syndrome of HIV and associated factors: a study in a university hospital

Resumo O uso de antirretroviral aumentou a sobrevida dos portadores do HIV, porém pode acarretar efeitos colaterais, como a síndrome lipodistrófica. O objetivo deste artigo é identificar a frequência da síndrome lipodistrófica e seus fatores associados em pacientes portadores do HIV em uso de terapia antiretroviral. Estudo transversal com pacientes acompanhados ambulatorialmente. A síndrome foi avaliada pela associação de dois parâmetros: emagrecimento periférico através da escala de gravidade de lipodistrofia e acúmulo de gordura central, mensurado pela relação cintura quadril. Para identificar as variáveis associadas foi realizada a análise de Regressão de Poisson. Dos 104 pacientes avaliados, 27,9% apresentaram a síndrome. Após ajuste, ser do sexo feminino (RPajustada = 2,16 IC95%1,43-3,39), ter excesso de peso (RPajustada = 2,23 IC95%1,35-2,65) e um maior tempo de uso dos antirretrovirais (RPajustada = 1,64 IC95%1,16-2,78) permaneceram positivamente associados à síndrome. Por outro lado, foi observada uma associação negativa com a contagem de CD4 £ 350 (RPajustada = 0,39 IC95%0,10-0,97). A alta prevalência da síndrome e sua associação com grupos específicos reforçam a necessidade do adequado acompanhamento e identificação precoce como forma de intervir nos fatores modificáveis.

Abstract The use of antiretroviral drugs has increased the survival of HIV patients, but may have side effects, such as lipodystrophic syndrome. This article aims to identify the frequency of the lipodystrophic syndrome and its associated factors in patients with HIV using antiretroviral therapy. It involved a cross-sectional study with HIV patients, monitored on an outpatient basis. The syndrome was evaluated by the association of two parameters: peripheral weight loss through the lipodystrophy severity scale and central fat accumulation, measured by the hip waist ratio. Poisson regression analysis was performed to identify the associated variables. Of the 104 patients evaluated, 27.9% presented the syndrome. After adjustment, the female sex (PRadjusted = 2.16 CI95% 1.43-3.39), being overweight (PRadjusted = 2.23 CI95% 1.35-2.65) and a longer period of use of antiretrovirals (PRadjusted = 1.64 CI95% 1.16-2.78), remained positively associated with the syndrome. On the other hand, a negative association with CD4 count £ 350 (PRadjusted = 0.39 CI95% 0.10-0.97) was observed The high prevalence of the syndrome and its association with specific groups reinforce the need for adequate follow-up and early identification to intervene in modifiable factors.

Association between changes in body fat distribution, biochemical profile, time of HIV diagnosis, and antiretroviral treatment in adults living with and without virus infection

SUMMARY OBJECTIVES Individuals living with HIV seem to be more prone to changes in the redistribution of body fat, characterized as lipodystrophy, which may occur in conjunction with metabolic diseases. In the present study, such impacts were assessed in adults with and without HIV and associated with the time of virus diagnosis and treatment with antiretroviral. METHODS A cross-sectional study with 123 adults, in which 87 had HIV and 36 without HIV, of both sexes, in outpatient follow-up at the Specialized Care Service (SAE) in Macaé-RJ. The following were made: 1) Alteration in body fat distribution, measured by anthropometric parameters and self-reported lipodystrophy; 2) Biochemical profile; 3) Association between HIV diagnosis time and antiretroviral treatment. RESULTS 54.47% (n = 67) males, 45.52% (n = 56) females, mean age 37 years. Of these 87 were people living with HIV, 29% (n = 25) had self-reported lipodystrophy, mean time of virus infection, and antiretroviral treatment (5.80 ± 4.56 and 5.14 ± 3.82 years), respectively. Patients with self-reported lipodystrophy had a greater change in body fat distribution between 3-6 years of HIV diagnosis and a negative cholesterol profile. The antiretroviral treatment time influenced total cholesterol and triglycerides, even for patients without self-reported lipodystrophy, with a further nine years under treatment. CONCLUSION In this study, the negative cholesterol profile was mainly related to antiretroviral treatment time, even for patients without self-reported lipodystrophy, and changes in body fat distribution, measured by anthropometry, was especially associated with time for HIV infection in those with lipodystrophy self-reported.

RESUMO OBJETIVOS Indivíduos vivendo com HIV parecem mais propensos às alterações na redistribuição da gordura corporal, caracterizada como lipodistrofia, podendo acontecer em conjunto com as metabólicas. No presente estudo avaliaram-se tais impactos em adultos com e sem HIV e se associou ao tempo de diagnóstico do vírus e tratamento com antirretroviral. MÉTODOS Estudo tipo transversal, com 123 adultos, no qual 87 tinham HIV e 36 sem HIV, de ambos os sexos, em seguimento ambulatorial no Serviço de Atendimento Especializado (SAE) em Macaé - RJ. Foram feitos: 1) Alteração na distribuição da gordura corporal, mensurados por parâmetros antropométricos e lipodistrofia autorreferida; 2) Perfil bioquímico; 3) Associação entre tempo diagnóstico do HIV e tratamento com antirretroviral. RESULTADOS Incluíram-se 54,47% (n=67) do sexo masculino, 45,52% (n=56) do feminino, com média de idade de 37 anos. Destes, 87 eram pessoas vivendo com HIV, 29% (n=25) possuíam lipodistrofia autorreferida; tempo médio de infecção pelo vírus e tratamento antirretroviral (5,80±4,56 e 5,14±3,82 anos), respectivamente. Os pacientes com lipodistrofia autorreferida tiveram maior alteração na distribuição da gordura corporal entre 3-6 anos de diagnóstico do HIV e um perfil colesterolêmico negativo. O tempo de tratamento com antirretroviral influenciou o colesterol total e os triglicerídeos, mesmo para os pacientes sem lipodistrofia autorreferida, com mais de nove anos sob tratamento. CONCLUSÃO Neste estudo, o perfil colesterolêmico negativo se relacionou principalmente ao tempo de tratamento com antirretroviral, mesmo para os pacientes sem lipodistrofia autorreferida e as alterações na distribuição da gordura corporal, mensuradas por antropometria, se associaram especialmente ao tempo de infecção pelo HIV naqueles com lipodistrofia autorreferida.

Psychosocial Correlates of Body Image and Lipodystrophy in Women Aging With HIV.

Body image disturbance is increasingly relevant as women living with HIV (WLWH) live longer. We explored body image disturbance and changes in fat distribution (lipodystrophy) in 63 WLWH (mean age = 51 years) and evaluated associations among lipodystrophy, body image, and psychosocial variables. Eighty-one percent of participants reported one or more body parts (of six assessed) demonstrating lipodystrophy, and more than one third reported three or more affected body parts. Increased belt/waist (58%) and increased chest/breast (39%) sizes were most common. More diffuse lipodystrophy was significantly associated with poorer body image (F[2,54] = 11.86, p < .001, partial η = .313) and anxiety (F[2,52] = 3.82, p = .029, partial η = .133) after controlling for age and duration of infection. Lipodystrophy was prevalent in our sample; more diffuse lipodystrophy was associated with anxiety and poor body image. Providers should assess lipodystrophy in older WLWH and provide referrals for mental health services.

CROI 2016: Complications of HIV Infection and Antiretroviral Therapy.

Noncommunicable conditions such as cardiovascular disease, hypertension, renal and bone diseases, and malignancies as well as infectious complications are an ongoing concern during the course of treated HIV disease. Research in this area continues to focus on the epidemiology and risk factors for these conditions, on identifying the contributions of HIV-related immunopathology to specific and collective end-organ diseases, and on evaluating interventions to prevent or reduce the morbidity associated with these conditions. Data presented at the 2016 Conference on Retroviruses and Opportunistic Infections provided new insights into all of these areas.

HIV and noncommunicable diseases: the Asian perspective.

Asia is seeing a rise in noncommunicable diseases in their general population and among people living with HIV. Many Asians have low body weight, which can lead to higher plasma concentrations of antiretrovirals and, as a result, their toxicities. Examples are metabolic complications from protease inhibitors, chronic kidney disease from tenofovir, and hepatotoxicity from nevirapine. Asia has not only the highest burden of hepatitis B viral infection than any other continent but also a predominance of genotypes B and C, the latter associated with higher risk for hepatocellular carcinoma. HIV-associated neurocognitive disorders are equally common among Asians as other populations. Diastolic dysfunction and asymptomatic myocardial ischemia are not infrequent. Non-Hodgkin lymphoma is the most common AIDS-related cancer, whereas Kaposi sarcoma is relatively infrequent. Emerging data show high prevalence of human papillomavirus-associated anal dysplasia in men who have sex with men. Resource-limited countries in Asia suffer from lack of resources for national screening programs of noncommunicable diseases, which, in turn, limits the epidemiologic data that exist to guide the use of national health resources.

Prevalence of lipodystrophy and risk factors for dyslipidemia in HIV-infected children in Brazil

The aim of present study was to describe the frequency of lipodystrophy syndrome associated with HIV (LSHIV) and factors associated with dyslipidemia in Brazilian HIV infected children. HIV infected children on antiretroviral treatment were evaluated (nutritional assessment, physical examination, and laboratory tests) in this cross-sectional study. Univariate analysis was performed using Mann-Whitney test or Fisher's exact test followed by logistic regression analysis. Presence of dyslipidemia (fasting cholesterol >200 mg/dl or triglycerides >130 mg/dl) was the dependent variable. 90 children were enrolled. The mean age was 10.6 years (3-16 years), and 52 (58%) were female. LSHIV was detected in 46 children (51%). Factors independently associated with dyslipidemia were: low intake of vegetables/fruits (OR = 3.47, 95%CI = 1.04-11.55), current use of lopinavir/ritonavir (OR = 2.91, 95%CI = 1.11-7.67). In conclusion, LSHIV was frequently observed; inadequate dietary intake of sugars and fats, as well as current use of lopinavir/ritonavir was associated with dyslipidemia.

Lipodystrophy syndrome in HIV treatment-multiexperienced patients: implication of resistin.

BACKGROUND: Impaired production of adipocytokines is a major factor incriminated in the occurrence of lipodystrophy (LD). OBJECTIVE: To evaluate LD prevalence and subtypes in HIV treatment-multiexperienced patients, and to determine the correlations between adipocytokines and LD subtypes. METHODS: Cross-sectional study in a Romanian tertiary care hospital, between 2008 and 2010, in HIV-positive patients, undergoing cART for ≥6 months. LD diagnosis, based on clinical and anthropometric data, was classified into lipoatrophy (LA), lipohypertrophy (LH) and mixed fat redistribution (MFR). Blood samples were collected for leptin, adiponectin and resistin assessments. RESULTS: We included 100 patients, 44 % with LD, among which LA had 63 %. LA patients had sex ratio, median age, treatment duration and median number of ARV regimens of 1, 20, 93 and 3.5 compared to non-LD patients: 1.65, 31, 44 and 1. LH and MFR patients were older and had higher total and LDL cholesterol versus non-LD patients. For both overall group and female group, LA was associated in univariate and multivariate analysis with increased resistin (p = 0.02 and 0.04) and number of ARV regimens (p < 0.001). Determination coefficient (Nagelkerke R (2)) of increased resistin and the number of ARV combinations in the presence of LA was 33 % in overall group and 47 % in female patients. CONCLUSIONS: In our young HIV-positive population, LD had high prevalence with predominance of LA subtype. LA was associated with high resistin levels and greater number of ARV regimens in overall group and female subgroup. Resistin could be used as a marker of peripheral adipose tissue loss and might be used as a target for new anti-LD therapeutic strategies.

Prevalence and factors associated with lipodystrophy in AIDS patients

Introduction: The published literature shows an increased occurrence of adverse events, such as human immunodeficiency virus (HIV)-associated lipodystrophy syndrome, that are associated with the continuous use of antiretroviral therapy. This study was performed to estimate the prevalence and factors associated with lipodystrophy in acquired immune deficiency syndrome (AIDS) patients. Methods: We conducted a cross-sectional study between October 2012 and February 2013. The sample consisted of patients with AIDS who attended the Outpatient Treatment Center for Infectious Diseases at Nereu Ramos Hospital, Florianópolis, State of Santa Catarina, Brazil. We collected information on demographics, lifestyle, HIV infection, and clinical aspects of the disease. Self-reported signs of lipodystrophy and body measurements were used for lipodystrophy diagnosis. Results: We studied 74 patients (mean age 44.3±9.2 years; 60.8% men). Among the patients, 45.9% were smokers, 31.1% consumed alcoholic beverages, and 55.4% were sedentary. The prevalence of lipodystrophy was 32.4%, and sedentary subjects had a higher prevalence of lipodystrophy compared with physically active individuals. Conclusions: The prevalence of lipodystrophy was 32.4%. Physical activity was considered an independent protective factor against the onset of HIV-associated lipodystrophy. .

Characteristics and factors associated with the clinical forms of lipoatrophy during highly active antiretroviral therapy in Ouagadougou, Burkina Faso.

BACKGROUND: We aimed to study the factors associated with clinical forms of lipoatrophy in patients receiving highly active antiretroviral therapy (HAART) in Yalgado Ouédraogo Teaching Hospital, Ouagadougou, Burkina Faso. METHODS: This cross-sectional review from March 10 to November 10, 2011, included a nonprobability sample of HIV-infected adults receiving antiretroviral (ARV) medications for at least 6 months and monitored in the internal medicine department. The diagnosis of lipoatrophy was clinical. RESULTS: Three hundred patients were included. The sex ratio was 0.4 and the mean age was 42.1 ± 8.5 years. The mean duration of HAART was 73.2 ± 30.9 months. In all, 97 (32.3%) patients had lipoatrophy: 75 (25%) isolated and 22 (7.3%) mixed syndrome. Facial lipoatrophy was frequent (61.8%). Isolated lipoatrophy was associated with male sex (P = .002) and body mass index ≤25 (P < .05). Mixed syndrome was associated with female sex (P = .002), age >42 years (P < .05), physical activity (P = .003), smoking (P = .001), stavudine (d4T; P = .0001), or protease inhibitors (P = .01). CONCLUSION: Prevention of lipoatrophy associated with HAART requires the exclusion of modifiable risk factors that we identified.

HIV-associated lipodystrophy in South Africa: the impact on the patient and the impact on the plastic surgeon.

BACKGROUND: With 67% of the world's human immunodeficiency virus (HIV)-infected population existing in sub-Saharan Africa and recent access to highly active antiretroviral therapy (HAART), the demand for plastic surgical intervention in addressing lipodystrophy has expanded dramatically. We assessed the rate of lipodystrophy in a random clinic cohort, the demand for surgical correction and risk of treatment non-compliance. METHOD: Questionnaire and database cross-sectional review of 554 patients over a 3-month period at the Themba Lethu Clinic, Johannesburg, South Africa. RESULTS: A total of 479 patients completed the questionnaire, 83% were female. Nearly 90% of patients were on, or had been on, stavudine (d4T). The prevalence of lipodystrophy was 11.7%. Nearly 5.9% of patients had considered stopping treatment due to the development of lipodystrophy; 47% would consider surgery to correct unwanted physical changes. Male patients were satisfied by the changes they noted in their physical features following treatment (pre-treatment satisfaction 38% vs. post-treatment satisfaction of 94%). Female patients had 6.5 times more breast hypertrophy-related symptoms than in their pre-treatment state. CONCLUSION: We identify a prevalence of 11.7% of patients with HIV-associated lipodystrophy, of whom 5.9% would consider non-compliance on the basis of this side effect alone. The demand for surgical correction is significant and needs to be addressed.

Polymorphisms in Fas gene is associated with HIV-related lipoatrophy in Thai patients.

The present study aimed to evaluate the role of genetic polymorphisms in the emergence of lipoatrophy or lipodystrophy in HIV-infected patients with antiretroviral therapy (ART) in Thailand. Position 455 upstream of the Apolipoprotein C3 gene (ApoC3 T-455C, rs2854116), codon 64 of the Beta3 adrenergic receptor gene (ARß3 Tcod64C, rs4994), and position 670 upstream of the Fas gene (Fas A-670G, rs1800682) were genotyped in 829 HIV-infected Thai patients who had started ART. Crude and adjusted incidence rate ratios (IRR) were calculated using Poisson regression. The serum levels of cholesterol, triglycerides, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were also analyzed. Multivariate analysis revealed an association between the Fas -670AA genotype, but not the ApoC3 -455 or ARß3 cod64 genotypes, with the incidence of lipoatrophy after adjusting for gender and stavudine (d4T)-containing regimens (IRR=1.72, 95% CI=1.20-2.45, p=0.003). However, ApoC3 -455C homozygous patients showed elevated serum levels of triglycerides, while this genotype did not affect serum total cholesterol, HDL, or LDL levels in patients with lipoatrophy or lipodystrophy. In contrast, the ARß3 cod64 genotype did not show any significant association with the serum levels of cholesterol, triglycerides, HDL, or LDL. In conclusion, Fas -670AA affected the incidence of lipoatrophy in HIV-1-infected Thai patients, while the ApoC3 -455C allele affected the serum levels of triglycerides. These results confirmed the role of genetics in the development of ART-related metabolic disorders.

[Hypertriglyceridemic waist phenotype is a risk factor for subclinical atherosclerosis in human immunodeficiency virus-infected patients]. / El fenotipo "hipertrigliceridemia-cintura abdominal aumentada" es un factor de riesgo de aterosclerosis subclínica en pacientes con infección por el virus de la inmunodeficiencia humana.

BACKGROUND AND OBJECTIVE: To study the association between hypertriglyceridemic waist phenotype and the presence of subclinical atherosclerosis in human immunodeficiency virus (HIV) infected patients. PATIENTS AND METHODS: Cross sectional study. Hypertriglyceridemic waist phenotype was considered if the waist was ≥90cm and triglycerides ≥2.0mmol/l (178mg/dl) in men and ≥85cm and ≥1.5mmol/L (133mg/dl) in women, respectively. We used the intima-media thickness (IMT) to detect carotid subclinical atherosclerosis. RESULTS: We analyzed 152 patients, of whom 128 (84.2%) were receiving antiretroviral therapy, 40.7% were receiving protease inhibitors and 38.1% were treated with non-nucleoside reverse transcriptase inhibitors. The prevalence of hypertriglyceridemic waist phenotype was 23.6% (95% confidence interval [CI] 16.8-30.3%). Patients with hypertriglyceridemic waist phenotype had higher cardiovascular risk according to the Framingham score (11.09 [7.6] vs 3.88 [4], P=0.001) and lipodystrophy (33.3 vs. 13.7%, P=0.032) and metabolic syndrome (69.4 vs. 1.9%, P<0.001) were more frequent. The IMT was elevated in 21 (13.8%) patients. Hypertriglyceridemic waist phenotype (odds ratio [OR] 4.66 [95%CI 1.05-20.6; P = 0.043]) and metabolic syndrome (OR 3.74 [95%CI 1.25-11.23; P = 0.018]) were independently associated with higher IMT. CONCLUSIONS: The hypertriglyceridemic waist phenotype is a risk factor for subclinical atherosclerosis in HIV infected patients and it is useful to detect patients with lipodystrophy, metabolic syndrome and high cardiovascular risk.

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.

Prevalence of highly active antiretroviral therapy associated metabolic abnormalities and lipodystrophy in HIV infected patients.

BACKGROUND: Highly active antiretroviral therapy (HAART) improves the longevity of HIV patients. However, the side effect of the drugs leads to development of chronic metabolic and cardiovascular complications. OBJECTIVE: The aim of the study was to determine the prevalence and risk factors of the metabolic abnormalities and lipodystrophy among adult Ethiopian HIV infected patients on ART for one year and above. METHODS: A cross-sectional study was conducted among HIV infected patients on HAART for one year or more, attending the ART clinics of Tikur Anbessa Specialized hospital in Addis Ababa. A total of consecutive 356 HIV infected patients volunteered to participate in the study from July 2007 to January 2008. Data was collected using clinical interview technique on structured questionnaires and physical examination of the patient, 319 had biochemical tests performed. RESULTS: Three hundred fifty six HIV patients; 261 (73.1%) females and 95 (26%) males were studied. Two hundred nine (59.7%) patients were on Stavudine based and 135 (41.3%) were on Zidovudine based ART therapy. The overall prevalence of lipodystrophy was 68.3% (243), prevalence of hyperlipademia among 319 HIV patient was 56.9% Among these, the prevalence of hypercholesterolemia was 38.2%, high LDL cholesterol was 54.2% hypertryglyceredimeia was 15.2% Fasting hyperglycemia was 17.8% (IFG in 10.9% and overt diabetes in 6.9%). History of smoking was significantly associated with lipoatrophy and lipohypertrophy. ART regimen d4T was significantly associated with lipoatrophy. Duration of ART treatment > or = 1 yr was significantly associated with both lipoatrophy, lipohypertrophy and hypertriglyceredemia. CONCLUSIONS AND RECOMMENDATIONS: Lipodystrophies occurred in majority of patients on ART treatment for longer than one year, hyperlipaedemia and hyperglycaemia were also seen commonly in Ethiopian HIV patients on HAART. We recommend careful monitoring of metabolic abnormalities, examination of the patient for early detection of the side effect, change of the offending agents management of metabolic abnormalities.

Lipoatrofia facial associada ao HIV/AIDS: do advento aosconhecimentos atuais / HIV-Associated facial lipoatrophy: from the advent to current knowledge

O advento da AIDS trouxe novos desafios para a Dermatologia. A terapia antirretroviral mudou drasticamente a morbimortalidade associada à infecção pelo HIV/AIDS, mas contribuiu para o surgimento de outras novas situações que exigem abordagem adequada do dermatologista. A Síndrome Lipodistrófica Associada ao HIV/AIDS tem origem multifatorial, mas está fortemente associada ao uso dos antirretrovirais. Compreende alterações na distribuição da gordura corporal, acompanhada ou não de alterações metabólicas. A perda da gordura da face, chamada lipoatrofia facial, é dos sinais mais estigmatizantes da síndrome. Esta condição, muitas vezes reveladora da doença, trouxe de volta o estigma da AIDS. É necessário que os especialistas que atuam com pacientes com HIV/AIDS identifiquem estas alterações e busquem opções de tratamento, dentre as quais se destaca o implante com polimetilmetacrilato, que é disponibilizado para tratamento da lipoatrofia facial associada ao HIV/AIDS no Sistema Único de Saúde.

The advent of AIDS has brought new challenges to Dermatology. Antiretroviral therapy dramatically changed the morbidity and mortality associated with HIV / AIDS, but contributed to the emergence of other new situations that require adequate approach by the dermatologist. The HIV / AIDS Associated Lipodystrophy Syndrome is multifactorial in origin, but it is strongly associated with the use of antiretroviral drugs. It includes changes in body fat distribution, with or without metabolic changes. The loss of facial fat, called facial lipoatrophy, is one of the most stigmatizing signs of the syndrome. This condition, often revealing of the disease, brought back the stigma of AIDS. It is necessary that the specialists working with patients with HIV / AIDS identify these changes and seek treatment options, amongst which stands out the implant with polymethylmethacrylate, which is available for the treatment of HIV / AIDS facial lipoatrophy in the Brazilian Public Health System.

Lipodystrophy in HIV/AIDS patients with different levels of physical activity while on antiretroviral therapy / Lipodistrofia em pacientes com HIV/AIDS com diferentes hábitos de atividade física, em uso de terapia antirretroviral

INTRODUCTION: Lipodystrophy is related to the use of highly active antiretroviral therapy (HAART) and can cause aesthetic stigma and increase the risk of developing cardiovascular diseases. Physical activity may be a valid alternative for the treatment and prevention of lipodystrophy. However, few studies address this issue. The objective of this study was to assess lipodystrophy related to highly active antiretroviral therapy in HIV/AIDS patients with different physical activity habits. METHODS: The sample was composed of 42 HIV/AIDS patients taking HAART medication who were visiting the Counseling and Testing Center (CTC) in Presidente Prudente. The level of physical activity was obtained using the International Physical Activity Questionnaire (IPAQ); lipodystrophy was diagnosed using a self-report questionnaire that was administered to the patient and then followed up by medical confirmation. The percentage of trunk fat was estimated by dual X-Ray absorptiometry (DEXA). Information about sex, age, length of HAART treatment, CD4+ T lymphocyte count (CD4) and viral load was also collected. RESULTS: A higher prevalence of lipodystrophy was observed in the sedentary group when compared to the physically active group, which indicates that physical activity may be a protective factor in relation to the occurrence of lipodystrophy. The group that had a higher CD4 had a higher proportion of lipodystrophy and a higher proportion of younger and physically active individuals. The patients with lipodystrophy had a higher percentage of trunk fat and were more sedentary than active individuals. CONCLUSIONS: A physically active lifestyle has a protective effect against the occurrence of lipodystrophy related to HAART.

INTRODUÇÃO: A lipodistrofia relacionada ao uso de terapia antirretroviral (TARV) pode causar estigma estético e elevar o risco de doenças cardiovasculares. A atividade física pode ser uma alternativa válida para o tratamento e prevenção da lipodistrofia. Entretanto, poucos estudos tratam dessa temática. O objetivo deste estudo foi verificar a ocorrência de lipodistrofia relacionada ao uso de TARV em portadores de HIV/AIDS, com diferentes hábitos de atividades físicas. MÉTODOS: A casuística foi formada por 42 portadores de HIV em uso de TARV, do Centro de Testagem e Aconselhamento de Presidente Prudente. Para obtenção do nível de atividade física aplicou-se o Questionário Internacional de Atividade Física (IPAQ); a lipodistrofia foi diagnosticada pelo autorrelato do paciente e a confirmação médica. O percentual de gordura de tronco foi estimado pela absortometria por raio-X de dupla energia (DEXA). Foram coletados também dados referentes a sexo, idade, tempo de uso de TARV, valores de CD4 e carga viral. RESULTADOS: Verificou-se maior ocorrência de lipodistrofia no grupo sedentário quando comparado ao ativo, além de fator protetor da prática da atividade física em relação à ocorrência da lipodistrofia. O grupo com valores mais elevados de CD4 também apresentou maior proporção de sujeitos com lipodistrofia, além de maior proporção de ativos e de indivíduos com menor faixa etária. Os acometidos pela lipodistrofia apresentaram maiores valores de percentual de gordura de tronco, bem como, os sedentários em relação aos ativos. CONCLUSÕES: O estilo de vida fisicamente ativa resultou em efeito protetor para ocorrência da lipodistrofia relacionada ao uso da TARV.

Human immunodeficiency virus treatment-induced adipose tissue pathology and lipoatrophy: prevalence and metabolic consequences.

BACKGROUND: Lipoatrophy and metabolic complications of treatment of human immunodeficiency virus (HIV) infection may share common associations with adipose tissue pathology and inflammation. To investigate these relationships, we undertook a large-scale study of adipose tissue, body composition, and metabolic outcomes among HIV-infected adult men at a tertiary hospital HIV cohort during the period 2001-2007. METHODS: Assessments included adipose biopsies (n = 211) for investigation of adipocyte mitochondrial DNA content, adipocytokine expression, and adipose macrophage content; and whole-body dual-energy x-ray absorptiometry (DEXA) scans (n = 225) for objective body composition changes; 138 individuals contributed both biopsy and DEXA data. RESULTS: Compared with 78 treatment-naive control subjects, 98 zidovudine recipients (48%) and 49 stavudine recipients (67%) had leg fat measures <10% threshold value. Adipose samples associated with current stavudine or zidovudine (n = 99) revealed significant adipocyte mitochondrial DNA depletion, adipose tissue macrophage infiltration, and elevated proinflammatory cytokine levels, compared with samples from control subjects and nonthymidine nucleoside reverse-transcriptase inhibitor (NRTI) recipients (all P < .05). Improvements in adipose pathology after NRTI switching (n = 21 longitudinal samples) correlated with increased preswitch adipose inflammation and less severe fat loss (both P < .05). Elevated ratios of total to high-density lipoprotein cholesterol levels and Homeostatic Metabolic Assessment scores correlated independently with lipoatrophy severity (P < .05) and increased body mass index (P < .05) in thymidine NRTI-experienced individuals. No effect of demographic or HIV-related variables, or HIV protease inhibitor therapy exposure was detected. CONCLUSIONS: Adipose tissue pathology and lipoatrophic fat loss are highly prevalent among recipients of stavudine- or zidovudine-based HIV treatment and are associated with adverse metabolic outcomes. Restoring adipose tissue health appears to be an important issue in the long-term treatment of this patient population.
