Detaljerad beskrivning
This prospective cross-sectional study was conducted at the Section of Chemical Pathology, Department of Pathology and Laboratory Medicine, AKUH Karachi Pakistan after approval from Aga Khan University Hospital's Ethics Review Committee (ERC ID: 2019-1973-6924). Data of subjects tested for serum 25OHD between April 2020 to March 2021 was reviewed daily and those with 25OHD levels >150 ng/ml were contacted via telephone. Only the initial results of the subjects tested at Clinical Laboratory were included. Those with incomplete clinical history, 25OHD levels <150ng/ml, whose contact numbers were unavailable or not answering telephone calls were excluded. To maintain confidentiality all identifiers were removed, and study identity numbers were generated.
After explaining the reason for phone call, verbal informed consent was taken and clinical information of calcium and VD supplementation including prescribed or self-medicated, indications for prescription, formulation strength, total dosage, frequency, duration, and calcium status was collected on a structured clinical history forms. The hypercalcemia was labeled when serum calcium was >10.2 mg/dl.
Data analysis:
The statistical analysis was performed using the Microsoft Excel 2016. Subjects were categorized into two age groups: <18 years (pediatric) and ≥18 years (adult). Total doses of VD supplements were added to calculate cumulative supplementation and daily supplementation was calculated by dividing cumulative dose by duration of supplementation.
Descriptive statistics median (interquartile range, IQR) were calculated for numerical data while frequency (percentage) for categorical data. Frequencies of subjects with VD toxicity were derived and their correlates were evaluated in the both the age groups. Demographics (age and gender), calcium status of subjects, indications, formulation strengths, frequency, duration, cumulative and daily dose of supplementation were generated.
