ABSTRACT
OBJECTIVE: to make recommendations on the approach to nutritional problems (malnutrition, cachexia, micronutrient deficiency, obesity, lipodystrophy) affecting HIV-infected patients. METHODS: these recommendations have been agreed upon by a group of expertes in the nutrition and care of HIV-infected patients, on behalf of the different groups involved in drafting them. Therefore, the latest advances in pathophysiology, epidemiology, and clinical care presented in studies published in medical journals or at scientific meetings were evaluated. RESULTS: there is no single method of evaluating nutrition, and diferent techniques--CT, MRI, and DXA--must be combined. The energy requirements of symptomatic patients increase by 20-30%. There is no evidence to support the increase in protein or fat intake. Micronutrient supplementation in only necessary in special circumstances (vitamin A in children and pregnant woman). Aerobic and resistance excercise is beneficial both for cardiovascular health and for improving lean mass and muscular strength. It is important to follow the rules of food safety at every stage in the chain. Therapeutic intervention in anorexia and cachexia must be tailored, by combining nutritional and pharmacological support (appetite stimulants, anabolic steroids, and, in some cases, testosterone). Artificial nutrition (oral supplementation, enteral or parenteral nutrition) is safe and efficacious, and improves nutritional status and response to therapy. In children, nutritional recommendations must be made early, and are a necessary component of therapy. CONCLUSION: appropriate nutritional evaluation and relevant therapeutic action are an essential part of the care of HIV-infected patients.

Objetivo: realizar recomendaciones sobre el abordaje de los problemas nutricionales (malnutrición, caquexia, déficit de micronutrientes, obesidad, lipodistrofia) presentes en la infección VIH. Métodos: estas recomendaciones se han consensuado por un grupo de expertos en nutrición y en atención al enfermo VIH, en representación de las distintas sociedades firmantes. Para ello se han revisado los últimos avances fisiopatológicos, epidemiológicos y clínicos recogidos en estudios publicados en revistas médicas o presentados en congresos. Resultados: no existe un único método de valoración nutricional, debiendo combinarse cuestionarios y técnicas como TAC, RNM y DEXA. Los requerimientos energéticos en enfermos sintomáticos aumentan en un 20-30%. No existe evidencia que respalde el incremento del aporte proteico o graso. La suplementación de micronutrientes sólo es necesaria en circunstancias especiales (Vitamina A en niños y embarazadas). El ejercicio aeróbico de resistencia es beneficioso tanto para la salud cardiovascular como para mejorar la masa magra y la fuerza muscular. Es importante seguir normas de seguridad en toda la cadena alimentaria. La intervención terapéutica en la anorexia y caquexia debe ser individualizada, combinando soporte nutricional y farmacológico (estimulantes del apetito, agentes anabolizantes y testosterona en algún caso). La nutrición artificial (suplementación oral, nutrición enteral o parenteral) es segura y eficaz, mejorando el estado nutricional y la respuesta al tratamiento. En niños, las recomendaciones nutricionales deben ser muy precoces, formando necesariamente parte del tratamiento. Conclusión: La adecuada valoración nutricional y la pertinente actuación terapéutica son parte esencial de la asistencia del enfermo VIH

OBJECTIVES: Rash is the most frequent adverse event associated with nevirapine. The use of prednisone has been controversial in this setting. A double-blind placebo-controlled study was performed to evaluate its efficacy in nevirapine-induced rash prevention. DESIGN: Multicentered, randomized, double-blind, placebo-controlled clinical trial with prednisone (30 mg/day x 2 weeks). INCLUSION CRITERIA: HIV-1 infection; CD4 count >200 cells/mm3; plasma viral load (PVL) <5 log10 copies/ml; nevirapine (200 mg/day x 2 weeks, followed by 200 mg twice daily) plus stavudine and didanosine. Clinical follow-up was performed at 15, 30, and 60 days and thereafter every 2 months. RESULTS: In all, 75 evaluable patients were enrolled (39 prednisone/36 placebo). Median baseline CD4 + cell count was 390 cells/mm3 and PVL, 20,200 copies/ml. Overall, nine cases of rash (12.5%) were detected, seven (18%) in the prednisone group and two (5.5%) in the placebo group (odds ratio [OR], 3.85; 95% confidence interval [CI], 0.65-29.3; p =.11). Incidence of moderate-to-severe rashes leading to nevirapine withdrawal was 13.5% (5 of 37) in the prednisone group and 3% (1 of 35) in the placebo group ( p =.2). Median time to rash in both groups was 16 days. Adverse events that motivated withdrawal of therapy appeared in 6 patients from the prednisone group (15.4%) and 3 from the placebo group (8.3%) ( p =.3). CONCLUSION: Short-term prednisone administration does not prevent nevirapine rash, but might even increase its incidence.
