Abstract
Objectives

To assess the effect of oral cholecalciferol 50,000IU monthly administered in people living with HIV (PLHIV) and 25(OH)D deficiency followed over 48 weeks.

Methods

A prospective observational study was conducted in a cohort of 110 PLHIV with 25(OH)D levels<20ng/mL. Changes in 25(OH)D levels were evaluated at 3, 6, and 12 months of treatment. The percentages of patients who achieved 25(OH)D levels>20 and >30ng/mL and changes in bone mineral density (BMD) were assessed.

Results

One hundred ten PLHIV (79% men, mean age 49.46 years) were included. The mean (standard deviation, SD) time on antiretroviral treatment was 10.69 (8.31) years and all patients had a viral load<50copies/mL. The mean 25(OH)D levels of 15.10±3.22ng/mL at baseline increased significantly (P<0.001) to 27.89±7.79ng/mL at 3 months, 28.53±8.45ng/mL at 6 months and 27.89±7.92ng/mL at 12 months. A total of 87.27% had normal 25(OH)D levels at 12 months (>30ng/mL in 36.1% of patients and >20ng/mL in 51.5%). Parathormone levels (PTH) also decreased significantly. Treatment was safe and well tolerated. On the other hand, no significant changes were observed in BMD.

Conclusions

Monthly administration of 50,000IU of cholecalciferol was effective in normalizing 25(OH)D deficiency in 87% of PLHIV, without observing changes in bone mineral density.

Resumen
Objetivos

Evaluar el efecto de la administración oral de colecalciferol 50.000UI mensuales en las personas que viven con VIH (PVVIH) y con deficiencia de 25(OH)D, seguidas durante 48 semanas.

Métodos

Se realizó un estudio observacional prospectivo en una cohorte de 110PVVIH con niveles de 25(OH)D<20ng/ml. Se evaluaron los cambios en los niveles de 25(OH)D a los 3, 6 y 12 meses de tratamiento. Se analizaron los porcentajes de pacientes que alcanzaron niveles de 25(OH)D>20 y >30ng/ml, así como los cambios en la densidad mineral ósea (DMO).

Resultados

Se incluyeron 110PVVIH (79% varones, edad media de 49,46 años). El tiempo medio (desviación estándar [DE]) en tratamiento antirretroviral fue de 10,69 (8,31) años y todos los pacientes presentaron una carga viral <50 copias/ml. Los niveles medios de 25(OH)D de 15,10±3,22ng/ml al inicio aumentaron significativamente (p<0,001) a 27,89±7,79ng/ml a los 3 meses, 28,53±8,45ng/ml a los 6 meses y 27,89±7,92 ng/ml a los 12 meses. Un total del 87,27% alcanzó niveles normales de 25(OH)D a los 12 meses (> 30 ng/ml en el 36,1% de los pacientes y >20ng/ml en el 51,5%). Los niveles de parathormona (PTH) también disminuyeron significativamente. El tratamiento fue seguro y bien tolerado. Por otro lado, no se observaron cambios significativos en la DMO.

Conclusiones

La administración mensual de 50.000UI de colecalciferol fue efectiva para normalizar la deficiencia de 25(OH)D en el 87% de las PVVIH, sin observarse cambios en la densidad mineral ósea.
