Hidrolipodistrofia ginóide (H.L.D.G.), a celulite, é comumente tratada com cosméticos contendo extratos vegetais. O estudo realizado foi: ultra-sonografia na avaliação da espessura da hipoderme e a microcirculação cutânea; uso de termômetro infravermelho na medida da temperatura e análise das medidas antropométricas da uma formulação cosmética anticelulítica contendo extrato hidroglicólico de Trichilia catigua e Ptychopetalum olacoides Bentham (catuaba e marapuama). Foram realizadas medidas iniciais e após aplicação da formulação. Os resultados apresentaram alterações estatisticamente significativas para a temperatura cutânea e medidas antropométricas. Não houve diferenças estatisticamente significativas nas medidas da hipoderme e microcirculação. Considerando os resultados, a formulação avaliada possui potencial ação coadjuvante na redução da hidrolipodistrofia ginóide. As técnicas podem ser associadas em conjunto com a avaliação sensorial e apreciabilidade cosmética. Os requisitos chaves para a reprodutibilidade das técnicas incluem ambiente controlado, monitoramento e climatização dos voluntários, procedimentos de medidas padronizados, protocolos de aplicação realístico e operadores qualificados. / Gynoid lipodystrophy (H.L.D.G.), the cellulite, is usually treated by cosmetics containing vegetal extracts ingredients. The study related to: ultrasonography evaluating the hypodermis thickness and skin blood microcirculation; the usage of the infra-red thermometer in the measurement of skin temperature and the assessment of anthropometrics measurements of a coadjuvant cosmetic formula based on hydroglycolic extract of Trichilia catigua and Ptychopetalum olacoides Bentham (catuaba and marapuama). Measurements were taken at first and again after the use of the formulation. The results indicate that there were statistically significant changes for skin temperature and also anthropometrics measurements. There were no statistically significant differences neither in hypodermis nor in blood microcirculation. Considering the final results, the formulation studied had a potential coadjuvant role by decreasing gynoid lipodystrophy. These techniques can be associated together with sensory evaluation and cosmetic appreciability. The key requirements for the reproducibility of the technique include: controlled environments, volunteers acclimatization and monitoring, standardized measurements procedures, realistic application protocols and qualified operators.

Methods: A systematic review of literature was conducted through a search protocol developed by the authors: articles were searched in Pubmed, Lilacs and Cochrane, between 1996 and 2010, of the type: controlled clinical trial, randomized or crossover; were adults, living with HIV/Aids under anti-retroviral therapy showing no opportunistic diseases. The intervention of interest was oral nutritional supplementation and/or lifestyle changes through specific nutritional therapy: dyslipidaemia, insulin resistance, lipodystrophy and systemic arterial hypertension. For qualitative classification of the articles we used the Jadad scale. The clinical trials, was controlled, randomized, open label, with a target population of adults with Aids in antiretroviral therapy and without opportunistic diseases. In the study on adherence was held randomized controlled trial and open. Among the 165 patients randomly assigned to two treatment groups for nutritional / dietary. The group treatment 1 (T1) and Treatment 2 (T2) received nutrition care, and the stage of nutritional diagnosis performed similarly in both groups and with service until completing treatment. With respect to conduct diet therapy groups (T1) and (T2)received nutritional counseling, group T2 also received individualized dietary plan. The groups had returns quaterly (T1) and monthly (T2). We considered dietary before and after the intervention and attendance at meetings as parameters of adherence to treatment. Results: In a systematic review 385 papers were found and seven met the inclusion criteria. The interventions applied in such studies were: diet plus physical exercises, diet plus supplement and only supplements. Dyslipidaemia was the common outcome to all studies. The studies assessing supplementation with omega 3 found significant reduction on triglycerides. Specific diet plus omega 3 supplementation showed an increase on HDL cholesterol. Supplementation with chromo nycotinate showed no effect on dyslipidaemia. Lifestyle modification,including diet and physical activity, drastically reduced the waist circumference, lipodystrophy and systolic arterial pressure. In the clinical trial among 165 patients in the study were 83 T1 and 82 T2. At the end of 7,3 months, 20% patients dropped out of the nutrition therapy. The T1 and T2 groups showed no significant difference in relation to socio demographic parameters. 15,63% of group T2 reached the goal considered optimal for adhesion while 42.65% of group T1 were 100% adherence to queries. The T1 and T2 groups showed a reduction to the risk of food consumption, increased consumption of protective foods, increased fractioning meals in T2 group. Conclusion: In the systematic review by lowering triglycerides with omega 3 supplementation was the greatest nutritional intervention with scientific evidence. Prescription diet seems to be the most appropriate intervention to increase HDL. Still can not make inferences about the nutritional treatment of total cholesterol, LDL and insulin resistance. In the study of adherence, there were no differences between groups T1and T2, in relation to adherence and in relation to the goals of food consumption. / Objetivo: Avaliar o conhecimento científico disponível sobre o efeito do tratamento nutricional nas alterações metabólicas em pacientes com Aids e a adesão destes ao serviço de Nutrição e ao tratamento nutricional/dietoterápico. Métodos: Para revisão sistemática, conduziu-se revisão sistemática de literatura por meio de protocolo de busca nas bases de dados: Pubmed, LIlacs e Cochrane, entre 1996 e 2010, do tipo ensaio clínico, controlado, randomizado, crossover, sendo a população alvo: adultos, vivendo com HIV/Aids, em uso de terapia anti-retroviral e sem doenças oportunistas. A intervenção de interesse foi suplementação nutricional via oral e/ou mudança de estilo de vida através de tratamento dietoterápico específico: dislipidemia, resistência insulínica, lipodistrofia e hipertensão arterial sistêmica. Para o estudo de adesão realizou-se ensaio clínico controlado, randomizado e aberto. Cento e sessenta e cinco adultos com Aids em uso de TARV, alocados aleatoriamente em dois grupos para tratamento nutricional/dietoterápico. Os grupos Tratamento1(T1) e Tratamento 2 (T2) receberam consulta de nutrição, sendo a etapa de diagnóstico nutricional realizada de mesma forma em ambos os grupos e com atendimento até completar o tratamento. Os grupos (T1) e (T2) receberam orientações nutricionais, o grupo T2 recebeu ainda plano alimentar individualizado. O grupo T1 tinha agendamento de retornos trimestrais e o T2 mensal. Consideraram-se repercussões dietéticas após a intervenção e assiduidade às reuniões como parâmetros de adesão ao tratamento. Resultados: Na revisão sistemática, após localizar 385 artigos, sete foram incluídos. As intervenções utilizadas nesses estudos foram: dieta, dieta mais exercício físico, dieta mais suplemento e somente suplementos. Dislipidemia foi desfecho avaliado em todos os estudos. Os estudos que avaliaram suplementação com ômega 3 encontraram redução significativa dos triglicérides. Dieta específica mais suplementação de ômega 3 mostrou aumento de HDL-colesterol. Suplementação com nicotinato de cromo não teve efeito sobre a dislipidemia. Modificação de estilo de vida reduziu, significativamente a circunferência da cintura, lipodistrofia e pressão arterial sistólica. No ensaio clínico dentre os 165 pacientes incluídos no estudo 83 receberam o T1 e 82 o T2. Ao final de 7,3 meses, 20% pacientes desistiram do tratamento nutricional. 15,63% dos pacientes do grupo T2 e 42,65% do grupo T2 atingiram a meta considerada ótima para adesão. Os grupos T1 e T2 apresentaram redução para o consumo de alimento de risco, aumento do consumo de alimentos de proteção, aumento e no fracionamento das refeições no grupo. Conclusão: Na revisão sistemática a redução de triglicérides pela suplementação com ômega 3 foi a intervenção nutricional com maiores evidências científicas. A prescrição de dieta parece ser a intervenção mais adequada para aumentar HDL. Ainda não é possível fazer inferências sobre o tratamento nutricional do colesterol total, LDL e resistência insulínica. No estudo de adesão, não houve diferenças entre os grupos T1 e T2, em relação à adesão às consultas analisada pela assiduidade e em relação às metas de consumo alimentar avaliada pelas modificações de hábitos alimentares.

Association entre les déterminants du style de vie, l'ostéoporose et la lipodystrophie chez les personnes vivant avec le VIH : une analyse transversale de la Cohorte canadienne VIH et vieillissement.

Poirier, Marc-Antoine 09 1900 (has links)
Introduction: Les personnes vivant avec le VIH (PVVIH) présentent des risques accrus d’ostéoporose et de lipodystrophie. Peu d’études se sont penchées sur l’association entre les déterminants du style de vie, le risque d’ostéoporose et le risque de lipodystrophie chez les PVVIH. Objectifs: L’objectif primaire était d’évaluer l’association entre l’ostéoporose, la lipodystrophie ainsi que différents déterminants du style de vie chez les PVVIH. Méthodologie: Tous les participants de la Cohorte canadienne VIH et vieillissement (CCVV) avec des données sur la densité minérale osseuse (DMO), mesurée par absortiométrie biphotonique à rayons X (DXA), ont été inclus dans cette étude transversale. Les déterminants du style de vie d’intérêt étaient : le revenu annuel, le niveau d’éducation, l’exercice physique ainsi que les consommations d’alcool, de tabac et de drogues illicites. Les covariables mesurées incluaient l’historique complet de la médication antirétrovirale, les comorbidités, les co-infections, la charge virale, le compte de CD4+ au recrutement et le compte de CD4+ nadir. L’ostéoporose a été définie par un score T de -2.5 ou moins. La lipodystrophie, évaluée par la composition corporelle via DXA, a été définie par un fat mass ratio (rapport des pourcentages de gras entre le tronc et les membres inférieurs) supérieur à 1.33 pour les femmes et 1.96 pour les hommes. Les rapports des cotes et les intervalles de confiance à 95% (IC95%) au recrutement ont été estimés en utilisant des régressions logistiques multivariées. Résultats: Nous avons inclus 547 PVVIH (âge médian 55 ans, 88% d’hommes) et 97 contrôles séronégatifs au VIH (âge médian 54 ans, 54% d’hommes). L’ostéoporose était présente chez 13% des PVVIH et 6% des contrôles (OR 2.21, IC 95% [0.96 – 6.06]). La lipodystrophie était présente chez 138 (28.3%, IC 95% 24.3 – 32.3%) des 487 PVVIH avec des données sur la disposition du gras corporel. Aucun des déterminants du style de vie était associé à l’ostéoporose ou à la lipodystrophie. Par contre, les covariables associées à un risque accru d’ostéoporose étaient l’âge avancé, un indice de masse corporelle (IMC) réduit et la co-infection à l’hépatite C. Les covariables associées au risque accru de lipodystrophie étaient l’âge avancé, l’hypertension, l’exposition prolongée aux antirétroviraux, ainsi que les expositions prolongées aux inhibiteurs nucléosidiques de la transcriptase inverse (INTI) et aux inhibiteurs de l’intégrase (INI). Conclusion: Aucune association n’a été décelée entre les déterminants du style de vie étudiés et l’ostéoporose ou la lipodystrophie. / Background: As a consequence of ART, people living with HIV (PLWH) are at higher risk for osteoporosis and lipodystrophy. However, the risk may also be influenced by lifestyle factors, but few studies have explored the association between modifiable lifestyle factors and the risk of osteoporosis or lipodystrophy in the PLWH population. Objectives: Our primary objective was to evaluate the lifestyle factors in relation to the risks of osteoporosis and lipodystrophy in a PLWH-based cohort. Methods: We conducted a cross-sectional analysis of data from the Canadian HIV and Aging Cohort Study (CHACS). We included all participants with available bone mineral density T-scores, which were measured by dual-energy X-ray absorptiometry (DXA) scans. Lifestyle risk factors of interest included annual income, education level, alcohol intake, tobacco use, illicit drug use and physical exercise. Other covariates considered were full antiretroviral medication history, medical comorbidities, coinfections, viral load, nadir CD4+ and current CD4+ count. Osteoporosis was defined by a T-score of -2.5 or lower at any of the measured sites. Lipodystrophy was assessed on whole body DXA and defined as a fat mass ratio (the ratio between trunk and lower limbs fat mass) greater than 1.33 for women and 1.96 for men. Baseline prevalence odds ratios (ORs) and 95% confidence intervals (95% CIs) were estimated by multivariate logistic regressions. Results: We included 547 PLWH (median age 55 years, 88% males) and 97 HIV-uninfected controls (median age 57 years, 64% males). Osteoporosis was present in 13.0% of PLWH (95% CI 10.2 – 15.8%) and 6% of controls (95% CI 1.4 – 11.0%); the OR of osteoporosis for HIV seropositivity was 2.21 (95% CI [0.96 – 6.06]). Lipodystrophy was found in 138 (28.3%, 95% CI 24.3 – 32.3%) of the 487 PLWH for which a fat mass ratio (FMR) was available. None of the lifestyle factors of interest were associated with osteoporosis or lipodystrophy. However, covariates associated with an increased risk of osteoporosis were increasing age, lower body mass index (BMI) and hepatitis C coinfection. Covariates associated with an increased risk of lipodystrophy were older age, hypertension, longer antiretroviral duration, and longer exposure to nucleoside reverse transcriptase inhibitors (NRTIs) and integrase strand inhibitors (INSTIs). Conclusion: No association was found between any of the lifestyle factors of interest and osteoporosis or lipodystrophy.
