RESUMEN
Changes in bone mineral density (BMD) are common in adults infected with human immunodeficiency virus (HIV). There are few studies evaluating bone involvement in children infected. OBJECTIVE: To evaluate BMD in vertically HIV-infected children. METHODS: We studied 53 infected children (8-18 years) from five hospitals. Disease status, nutritional assessment, vitamin D (25-OHD) levels and immunological status were recorded. BMD was measured by densitometry. Descriptive analysis, comparison of means and simple and multiple linear regression were used. RESULTS: 88.7% children were in stage B and C, 57% were eutrophic and 18.9% had short stature. 33.3% had 25-OHD levels < 20 ng / ml. 11%, 6% and 4% of the children had BMD <-2DE in hip, spine and whole body respectively. BMD was correlated with BMI, height, disease stage and years of treatment. Only protease inhibitors (PIs) maintained their significance when adjusted for other variables. CONCLUSION: children infected with HIV had lower BMD by age compared to NHANES III data. The severity of the disease, height, zBMI, years of treatment with antiretrovirals, mainly IP, are related to the reduction of bone mass.

Resumen Los cambios en la densidad mineral ósea (DMO) son comunes en adultos infectados con virus de la inmunodeficiencia humana (VIH). Existen pocos estudios que evalúen el compromiso óseo en niños. Objetivo: Evaluar la DMO en niños infectados verticalmente por VIH. Métodos: Se estudiaron 53 niños infectados (8-18) de cinco hospitales. Se registró severidad de enfermedad, evaluación nutricional, vitamina D (25-OHD) y estado inmunológico. La DMO se midió mediante densitometría. Se utilizó análisis descriptivo, comparación de medias y regresión lineal simple y múltiple. Resultados: El 88,7% estaban en estadio B y C, 57% eran eutróficos y 18,9% tenían talla baja. El 33,3% presentaba niveles de 25-OHD < 20 ng/ml. El 11%, 6% y 4% de los niños tenían DMO < 2DE en cadera, columna y cuerpo entero, respectivamente. La DMO se correlacionó con IMC, talla, severidad de enfermedad y años de tratamiento. Sólo inhibidores de las proteasas (IP) mantuvieron su significancia al ajustar por otras variables. Conclusión: Los niños infectados con VIH tuvieron DMO más baja por edad comparados con datos de NHANES III. La severidad de la enfermedad, talla, zIMC, los años de tratamiento con anti-retrovirales, principalmente IP, están relacionados con la reducción de la masa ósea.
