<p class="abstract"><strong>Background:</strong> Vitamin D has an important role in the regulation of calcium by stimulating intestinal absorption of calcium and phosphorous and osteoclastic resorption of bone thus being critical building bone. Given the high prevalence, severity, and cost of osteoporotic fractures, prevention strategies that are effective, low in cost and well tolerated are needed. One promising prevention strategy may be vitamin D supplementation. This animal study was done in order to establish the role of Vitamin D in fracture healing among rabbits.</p><p class="abstract"><strong>Methods:</strong> 8 rabbits were involved in the study with 4 in the control group &amp; 4 in the test group. A fracture was surgically induced on both the groups following which a single high dose of vitamin D was administered intra muscular injection to the test group and normal saline for the control group. Biomechanical properties of the fractured bones such as energy absorbed until fracture (EAUF), maximum load (N) and diameter at the fracture site (D) were assessed 12 weeks later.<strong></strong></p><p class="abstract"><strong>Results:</strong> Mean value of EAUF for test group was 401.8 N-mm and control group was 404 N-mm. Mean value of maximum load in control group is 228.8 N and for test group is 186.9 N.</p><strong>Conclusions:</strong>From the above results, the authors did not find any significant improvement in fracture healing in test group. Hence, further investigations are to be needed to prove the role of vitamin D3 in fracture healing.

Purpose: A growing number of studies indicate the importance of vitamin D supplementation for sports performance. However, the effects of a single high-dose vitamin D supplementation on ultramarathon-induced inflammation have not been investigated. We here analyzed the effect of a single high-dose vitamin D supplementation on the inflammatory marker levels in ultramarathon runners after an ultramarathon run (maximal run 240 km). Methods: In the study, 35 runners (amateurs) were assigned into two groups: single high-dose vitamin D supplementation group, administered vitamin D (150,000 IU) in vegetable oil 24 h before the start of the run (n = 16); and placebo group (n = 19). Blood was collected for analysis 24 h before, immediately after, and 24 h after the run. Results: Serum 25(OH)D levels were significantly increased after the ultramarathon in both groups. The increase was greater in the vitamin D group than in the control group. Based on post-hoc and other analyses, the increase in interleukin 6 and 10, and resistin levels immediately after the run was significantly higher in runners in the control group than that in those in the supplementation group. Leptin, oncostatin M, and metalloproteinase tissue inhibitor levels were significantly decreased in both groups after the run, regardless of the supplementation. Conclusions: Ultramarathon significantly increases the serum 25(OH)D levels. Attenuation of changes in interleukin levels upon vitamin D supplementation confirmed that vitamin D has anti-inflammatory effect on exercise-induced inflammation.

The Impact

Introduction: Observational studies indicate a significant impact of serum 25(OH)D concentration on incidence of hospital-acquired infections. However, we did not find any interventional study assessing the effect of vitamin D3 administration at the admission on the course of further hospitalization in internal medicine departments. Objective of the paper: Investigation of the impact of one-time high-dose vitamin D3 administration in elderly patients on the day of urgent admission to the hospital, on hospital-acquired infections. Materials and methods: A randomized, two-arms, open pilot study in 97 adults aged 60-100. A study group was given a single dose of 60,000 IU vitamin D3 and a control group was not subject to any intervention. Serum 25(OH)D and calcium were measured at the baseline and after 7 days. Results: 77.32% of studied patients were vitamin deficient, and among those, in 28.87% severe vitamin D deficiency was found. After single administration of 60,000 IU of vitamin D3, only 4 patients achieved recommended serum 25(OH)D concentration. The highest increase in serum 25(OH)D was observed in patients with severe deficiency. Numbers of observed nosocomial infections such as flu, hospital-acquired pneumonia or Klebsiella pneumoniae MBL+ infection did not differ significantly between study and control group, however there was a trend close to significance for lower incidence of Clostridium difficile infection in the vitamin D3 group. Conclusions: Preliminary results of the presented research indicate possible protective effect of single high dose of vitamin D3 against Clostridium difficile infection during hospitalization. Further research on larger group of patients, using higher dose of vitamin D3 is necessary.

Background: This study assessed the effects of weekly vitamin D (VD) supplementation on clinical and biological parameters after scaling and root planning (SRP) in the treatment of periodontitis and served to validate the VD dosage regimen. Methods: It was a monocentric, randomized, double-blind, placebo-controlled clinical trial with 6 months follow-up. Healthy Caucasian periodontitis patients presenting serum 25(OH) vitamin D3 below 30 ng/mL were randomly allocated to test group (SRP + VD 25,000 international units (IU)/week) or the control group (SRP + placebo). Results: A total of 59 patients were screened, 27 were included and 26 completed 3 months (M) and 21 completed 6M control. Test (n = 13) and control groups (n = 14) had similar 25(OH) vitamin D3 levels at baseline (17.6 ± 7.4 vs. 14.4 ± 5.2, respectively). After one month, there was a significant difference between groups (32.9 ± 5.2 vs. 16.1 ± 4.7), also seen at M3 and M6 (t-test, p < 0.001). Periodontal treatment was successful in both groups, since it resulted in a reduction of all measured clinical parameters at M3 and M6 (probing pocket depth (PPD), full mouth bleeding and plaque). However, the reduction in PPD was greater in the test group. Conclusions: In this short-term pilot study, no significant differences were observed between two groups. However, supplementation with VD tended to improve the treatment of periodontitis in patients with initial 25(OH) vitamin D3 < 30 ng/mL and proved safe and efficacious. NCT03162406.

BACKGROUND: Serum otolin-1 is an inner ear protein exclusively expressed in otoconia and cells of vestibule and cochlea. Serum otolin-1 is found to be quantifiable in patients with BPPV. Low Vitamin-D is associated with pathogenesis of BPPV. Since otoconia degeneration contributes to BPPV, lack of Vitamin-D may impact otoconia structure and integrity. OBJECTIVE: We aimed at studying the s.otolin-1 as biomarker and significance of vit-D in BPPV. MATERIAL AND METHOD: 23 patients in test and control groups respectively were chosen within the age of 20 to 65 years. All the patients were diagnosed using Dix Hallpike menouver and head roll test, patients were treated with appropriate Canal Reposition Menouver (CRM). RESULTS: Serum Otolin-1 levels among the test ranged from 366 to 882 pg/mL with mean of 585.17 pg/mL whereas in control group ranged from 223 to 462 pg/mL with mean of 335.26 pg/mL. Mean Vitamin-D levels among the test group was 22.67 ng/mL (Range = 6.3–68.4) and that of control 15.43 pg/mL (Range = 5.4–27.7) respectively. The relationship between the serum Otolin-1 and Vitamin-D was not statistically significant. CONCLUSION: Otolin-1 levels is increased in BPPV patients and is sensitive in BPPV, specificity needs to be validated. Role of vitamin-D with respect to inner ear proteins needs further investigation.

ABSTRACT Background Observational studies report higher blood pressure (BP) among individuals with lower 25-hydroxyvitamin D concentration. Whether dosage of vitamin D supplementation has a differential effect on BP control remains unclear. Objective The study aimed to determine if daily vitamin D supplementation with 2000 IU is more effective than 800 IU for BP control among older adults. Methods This randomized, double-blind, ancillary trial of the Zurich Multiple Endpoint Vitamin D Trial in Knee Osteoarthritis enrolled adults aged ≥60 y who underwent elective surgery due to severe knee osteoarthritis. Participants were randomly assigned to receive high dose (2000 IU) or standard dose (800 IU) daily vitamin D3 for 24 mo. Outcomes included daytime and 24-h mean systolic BP. BP variability and serum 25-hydroxyvitamin D concentration were examined in a post hoc and observational analysis. Results Of the 273 participants randomly assigned, 250 participants completed a follow-up 24-h ambulatory BP monitoring (mean age: 70.4 ± 6.4 y; 47.2% men). The difference in daytime mean systolic BP reduction between the 2000 IU (n = 123) and 800 IU (n = 127) groups was not statistically significant (−2.75 mm Hg vs. −3.94 mm Hg; difference: 1.18 mm Hg; 95% CI: −0.68, 3.05; P = 0.21), consistent with 24-h mean systolic BP. However, systolic BP variability was significantly reduced with 2000 IU (average real variability: −0.37 mm Hg) compared to 800 IU vitamin D3 (0.11 mm Hg; difference: −0.48 mm Hg; 95% CI: −0.94, −0.01; P = 0.045). Independent of group allocation, maximal reductions in mean BP were observed at 28.7 ng/mL of achieved serum 25-hydroxyvitamin D concentrations. Conclusions While daily 2000 IU and 800 IU vitamin D3 reduced mean systolic BP over 2 y to a small and similar extent, 2000 IU reduced mean systolic BP variability significantly more compared with 800 IU. However, without a placebo control group we cannot ascertain whether vitamin D supplementation effectively reduces BP. This trial was registered at www.clinicaltrials.gov as NCT00599807.
