Background & aims: Vitamin D is known as a neuroprotective hormone with anti-inflammatory and immune-modulatory properties. We evaluated the effect of vitamin D3 injection on vitamin D status and clinical outcomes in patients with low serum levels of 25-hydroxyvitamin D [25(OH)D] undergoing craniotomy for brain tumor resection.

Methods: Patients with benign brain tumors and serum 25(OH)D levels ≤20 ng/mL were randomized to two groups with an equal number of subjects. The study group (n = 30) received intramuscular injection of 300,000 IU vitamin D3 prior to surgery. The control group (n = 30) was left without intervention, and both groups underwent routine therapies.

Results: On day 5 after craniotomy, the serum 25(OH)D levels increased significantly in the study group (P= <0.001). The length of ICU and hospital stay was significantly lower in the study group compared to the control group (P = 0.01 and P = 0.008, respectively). It was true when the age, tumor size, tumor type, Karnofsky Performance Scale (KPS) score, and calcium and albumin levels at baseline entered the logistic regression model (OR = 0.17 (95%CI = 0.04-0.72, P = 0.01), and OR = 0.19 (95%CI = 0.04-0.82, P = 0.02), respectively). With and without the application of logistic regression analysis, there was no significant difference in perioperative complications.

Conclusions: Intramuscular injection of 300,000 IU of vitamin D3 in patients with low serum levels of 25(OH)D undergoing craniotomy, could rise safely the serum 25(OH)D level. This intervention, significantly reduced the length of ICU stay and hospitalization.
