<p class="abstract"><strong>Background:</strong> The prevalence of vitamin D deficiency is the burning topic worldwide. Vitamin D deficiency is a under diagnosed medical condition since a significant proportion of the population in many countries and regions around the world have low serum 25-hydroxy (OH) vitamin D levels. The aim of this study was to investigate the association between serum vitamin D deficiency and knee osteoarthritis (OA).</p><p class="abstract"><strong>Methods:</strong> The study population consists of 200 patients divided into two groups, group 1 and group 2. Group 1 with 100 subjects with no clinical features of knee osteoarthritis served as controls and group 2 consists of 100 patients of patients diagnosed with knee osteoarthritis. Serum 25-OH vitamin D was measured in all the participants by the enzyme-linked fluorescence assay (ELFA) method and concentrations <20 ng/ml was considered as deficient.<strong></strong></p><p class="abstract"><strong>Results:</strong> In group 1, 47% were male and 53% were female whereas in group 2, 41% were male and 59% were female. In group 1, only 8% are vitamin D deficiency whereas in group 2, 61% have vitamin D deficiency. There was a significant association between serum vitamin D and staging of knee OA.</p><p class="abstract"><strong>Conclusions:</strong> The present study findings showed a significant association between serum 25-OH vitamin D deficiency and in patients with knee OA.</p>
Proximal femoral fractures are very common in elderly patients. These fractures are thought to be associated with osteoporosis. Vitamin D is a possible risk factor for osteoporosis. So, this study was done to evaluate the association of serum vitamin D level with types of femoral fractures in elderly patients. Methods:The study was done between December 2017 to December 2019, 120 patients with age >60 years (male and female both) with proximal femoral fractures were studied. Serum 25-hydroxy vitamin D, calcium, phosphate, alkaline phosphatase levels, liver function test, renal function test, hemoglobin and complete blood counts of all the patients were assessed. Results: On assessment of serum vitamin D in proximal femoral fracture in elderly patients, it shows an increase incidence of proximal femoral fractures in patients with low serum vitamin D level. Fracture of neck of femur was most common among all. Type of fracture has no significant statistical relationship with serum vitamin D levels. Conclusions: Osteoporosis and serum vitamin D level depends on age and sex of the patient. But type of proximal femoral osteoporotic fracture has no association with either grade of osteoporosis or serum vitamin D level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
