Development and Evaluation of a Pharmacist-Driven Vitamin D Protocol for a Cystic Fibrosis Clinic.

OBJECTIVE: Vitamin D deficiency is commonly found in patients with cystic fibrosis (CF) and can have a negative effect on patients who are not at target goal according to Cystic Fibrosis Foundation's Vitamin D Deficiency Clinical Care Guidelines. The objective of this study is to determine the effectiveness of a pharmacist-driven vitamin D protocol (PDVDP) in improving, achieving, and maintaining 25-hydroxyvitamin D levels of patients in a pediatric CF clinic. METHODS: A retrospective chart review was conducted for pediatric patients with CF from August 2018 to March 2020 to determine the percent of patients with improvement in 25-hydroxyvitamin D levels to target goal (≥ 30 ng/mL). Patients' 25-hydroxyvitamin D levels at 6, 12, and 18 months after automatic enrollment into the PDVDP were compared to determine if improvement occurred, and to calculate relative percent increase of 25-hydroxyvitamin D levels for these patients. RESULTS: The mean 25-hydroxyvitamin D levels of the patients at baseline before the protocol and 6, 12, and 18 months after enrollment in the protocol were 23.2, 33.3, 32.7, and 34.6 ng/mL, respectively. These results demonstrate mean 25-hydroxyvitamin D levels at all follow-up time points were significantly greater than baseline (p < 0.001). At 6 months, 50% (n = 20) of pediatric patients reached the target 25-hydroxyvitamin D levels. CONCLUSIONS: The PDVDP was effective in increasing the number of patients able to reach target 25-hydroxyvitamin D levels. Our PDVDP process may also be used at other CF clinics to improve vitamin D outcomes collaboratively with the interprofessional CF team.

Obesity-related asthma in children: A role for vitamin D.

Excess adipose tissue predisposes to an enhanced inflammatory state and can contribute to the pathogenesis and severity of asthma. Vitamin D has anti-inflammatory properties and low-serum levels are seen in children with asthma and in children with obesity. Here we review the intersection of asthma, obesity, and hypovitaminosis D in children. Supplementation with vitamin D has been proposed as a simple, safe, and inexpensive adjunctive therapy in a number of disease states. However, little research has examined the pharmacokinetics of vitamin D and its therapeutic potential in children who suffer from obesity-related asthma.

Burkholderia glumae infection in an infant with chronic granulomatous disease.

An 8-month-old boy developed a necrotic lung mass from which Burkholderia glumae was recovered, leading to the diagnosis of chronic granulomatous disease (CGD). While other Burkholderia species have been identified as important pathogens in persons with CGD, B. glumae has not been previously reported to cause human infection.
