Validation Protocol of Vitamin D Supplementation in Patients with HIV-Infection.

Hypovitaminosis D and secondary hyperparathyroidism are frequent among HIV-infected patients. As there are no data about the best supplementation therapy both in treatment and in maintenance, we conducted an observational study of 300 HIV-infected patients for whom vitamin D and parathormone (PTH) had been measured in order to validate a protocol of vitamin D supplementation in patients with HIV-infection. Patients with vitamin D deficiency (defined as 25(OH)D < 10 ng/mL), insufficiency (defined as 25(OH)D < 20 ng/mL), or hyperparathyroidism (PTH > 65 pg/mL) were supplemented with cholecalciferol 16.000IU (0.266 mg) weekly (if deficiency) or fortnightly (if insufficiency or high PTH levels). Rates of normalization of 25(OH)D (levels above 20 ng/mL) and PTH levels (<65 pg/mL) were analyzed. Multivariate analysis of factors related to normalization was carried out. With a median follow-up of 2 years, 82.1% of patients with deficiency and 83.9% of cases with insufficiency reached levels above 20 ng/mL. However, only 67.2% of individuals with hyperparathyroidism at baseline reached target levels (<65 pg/mL). Independent factors for not achieving PTH objective were tenofovir (TDF) and protease inhibitors use. In HIV-infected patients with hypovitaminosis, the protocol of cholecalciferol supplementation normalized vitamin D levels regardless of antiretroviral regimen in a high proportion of patients but it was less effective to correct hyperparathyroidism.

Development of supportive services for frontotemporal dementias through community engagement.

The effect of early onset frontotemporal dementias (FTD) on spouses and children is profound, requiring different types of support services from pre-existing Alzheimer's disease interventions already in place. This article explores how the needs of families living with FTD resulted in three programme initiatives developed at Baycrest (an academic health sciences centre focused on ageing, in Toronto, Canada) to meet the needs of this population. These included an Internet-based videoconferencing support group for spouses, a website that provides support and counsel for children and their parents, and an adult day programme designed for FTD patients. The strength of these interventions is that services were developed with involvement of stakeholders in FTD care from the start, to deal with gaps in services in a sustainable way.
