Trial Outcomes & Findings for Calcium and Vitamin D to Optimize Bone Mass in Boys With Risperidone-induced Hyperprolactinemia (NCT NCT00799383)

NCT ID: NCT00799383

Last Updated: 2017-12-26

Results Overview

Peripheral quantitative computed tomography (pQCT) scan was obtained at the 4% and 20% sites of the nondominant radius to estimate trabecular and cortical BMD, respectively. A Stratec XCT-2000 scanner, software version 6.0 (Stratec, Inc., Pforzheim, Germany),was used. Trabecular BMD was measured as the mean density of the 85% central area of the bone's cross-section. Outcomes were measured at baseline, 18 weeks, and 36 weeks later.

Participant Flow

Between 02/2009 and 11/2013, medically-healthy 5 to 17 year-old risperidone-treated boys were enrolled, via screening of the electronic medical records, referrals, and word of mouth.

Participants were required to have been in treatment with risperidone for at least one year. They should have had a prolactin concentration ≥ 18.4 ng/ml on two occasions, within one week.

PRIMARY outcome

Timeframe: 36 weeks

Population: The number at baseline is smaller than the randomized number because bone scans with movement artifact were discarded. At late time points, the sample size reflects both attrition and exclusion due to movement artifact.

Peripheral quantitative computed tomography (pQCT) scan was obtained at the 4% and 20% sites of the nondominant radius to estimate trabecular and cortical BMD, respectively. A Stratec XCT-2000 scanner, software version 6.0 (Stratec, Inc., Pforzheim, Germany),was used. Trabecular BMD was measured as the mean density of the 85% central area of the bone's cross-section. Outcomes were measured at baseline, 18 weeks, and 36 weeks later.
