Introduction:

hypovitaminosis D is a highly spread condition worldwide, with clinical consequences that affect bone directly, among other manifestations. Antiepileptic drugs are among factors that cause this deficiency. In Uruguay, there is no information about hypovitaminosis D in children or patients who receive antiepileptic drugs.

Objectives:

to learn about the prevalence of hypovitaminosis D in children and adults in a health institution and to compare it with the prevalence in patients receiving antiepileptic drugs.

Method:

descriptive, transversal study conducted from March through December, 2017. The following variables were analysed: vitamin D, calcium, phosphorous, alkaline phosphatase and intact parathyroid hormone. Vitamin D insufficiency was defined as vitamin D levels of less than 30 ng per mL and deficiency as D levels of less than 20 ng per mL.

Results:

113 patients were included in the study, 60 of which were children and 53 adults. Global prevalence of vitamin D insufficiency was 89% and deficiency was 60%. In children taking antiepileptic drugs, the average vitamin D value was 17.5 ng/ml and it was 19.6 ng/ml for those not exposed to those drugs. In adults, the average vitamin D value was 18.1 in the population taking antiepileptic drugs and 16.9 in patients not taking that medication. The difference between average values was not statistically significant in children or adults. Calcemia levels observed were significantly lower in both children and adults taking antiepileptic drugs.

Conclusions:

vitamin D insufficiency was close to 90% and deficiency was over 50%. No significant differences were found between hypovitaminosis D groups, although reduced calcemia was observed in patients exposed to antiepileptic drugs. Further studies are necessary to analyse factors that cause this condition and its clinical consequences.
