Recommendations from SPNS/GEAM/SENBA/SENPE/AEDN/SEDCA/GESIDA on nutrition in the HIV-infected patient.

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

[Role of bone gammagraphy in the diagnosis of secondary osteomalacia in a patient treated with tenofovir]. / Utilidad de la gammagrafía ósea en el diagnóstico de osteomalacia secundaria en un paciente en tratamiento con tenofovir.

It is reported a HIV infected patient under antiretroviral therapy including tenofovir therapy who was referred to the Nuclear Medicine Department to complete bone pain study. A bone scan was performed at 3 hours after the injection of 740 MBq of 99mTc-MDP, revealing an abnormal distribution with characteristic changes compatible with osteomalacia. In further analysis, a secondary hyperparathyroidism and osteomalacia were diagnosed in the context of Fanconi syndrome, an infrequent complication described in patients under treatment with tenofovir.

Utilidad de la gammagrafía ósea en el diagnóstico de osteomalacia secundaria en un paciente en tratamiento con tenofovir / Role of bone gammagraphy in the diagnosis of osteomalacy secondary to tenofovir treatment

Presentamos el caso clínico de un paciente infectado por el virus de la inmunodeficiencia humana (VIH) que recibía tratamiento antirretrovírico, incluyendo el análogo de nucleótido tenofovir, y que acudió al servicio de Medicina Nuclear para completar un estudio por dolor óseo. En la gammagrafía ósea, realizada a las tres horas de la administración de 740 MBq de 99mTc-MDP, se observó un patrón anómalo de captación del trazador, con características compatibles con osteomalacia. En estudios analíticos realizados con posterioridad fue diagnosticado de osteomalacia e hiperparatiroidismo secundario a síndrome de Fanconi, que es una complicación infrecuente descrita en los pacientes tratados con tenofovir
