Background: Few preclinical studies have shown that Knee osteoarthritis (KOA) is linked to gut microbiome dysbiosis and chronic inflammation. This pilot study was designed to look at the gut microbiome composition in KOA patients and normal individuals with or without vitamin D deficiency (VDD, serum vitamin D <30 ng/mL). Methods: This pilot study was conducted prospectively in 24 participants. The faecal samples of all the participants were taken for DNA extraction. The V3-V4 region of 16s rRNA was amplified, and the library was prepared and sequenced on the Illumina Miseq platform. Results: The mean (±SD) age was 45.5 (±10.2) years with no defined comorbidities. Of 447 total Operational Taxonomic Units (OTUs), a differential abundance of 16 nominally significant OTUs between the groups was observed. Linear discriminate analysis (LEfSe) revealed a significant difference in bacteria among the study groups. Pseudobutyrivibrio and Odoribacter were specific for VDD, while Parabacteroides, Butyricimonas and Gordonibacter were abundant in the KOA_VDD group, and Peptococcus, Intestimonas, Delftia and Oribacterium were abundant in the KOA group. About 80% of bacterial species were common among different groups and hence labelled as core bacterial species. However, the core microbiome of KOA and VDD groups were not seen in the KOA_VDD group, suggesting that these bacterial groups were affected by the interaction of the KOA and VDD factors. Conclusion: Parabacteroides, Butyricimonas, Pseudobutyrivibrio, Odoribacter and Gordonibacter are the predominant bacteria in vitamin D deficient patients with or without KOA. Together these results indicate an association between the gut microbiome, vitamin D and knee osteoarthritis.

The present study was aimed to study the effect of Sublingual Vitamin D3 on Serum Vitamin D level in Vitamin D deficiency patients. This was a cross-sectional and interventional study. All the Vitamin D deficiency patients of age 18-60years and either gender, willing to participate in the study were included. Patients who had greater than 20 ng/ml were excluded from the study. The total number of participants in our study was 200, out of these 111 males and 89 females, the mean age in our study was 51.07 ± 7.39Yrs. All volunteers were given sublingual vitamin D3 (60,000IU) in six doses every fifteen days of follow up for 3 months. The subject’s serum 25(OH)D levels were estimated before and after the treatment of sublingual vitamin D3. There was a statistically significant difference in serum vitamin D3 level before 16.61±6.71 ng/ml and after 35.80±7.80 ng/ml after treatment with Sublingual Vitamin D3. Six doses of 60,000IU of Vitamin D3 sublingual route having improved the role of serum 25(OH)D levels in the treatment of Vitamin D3 deficiency patients.Keywords: Vitamin D3; Sublingual route

Abstract Objectives To study the nutritional status and prevalence of RBC folate, Serum folate and vitamin D deficiency among adolescents. Methods A cross sectional pilot study was carried out among 96 adolescents visiting outpatient department for refraction at tertiary care hospital in North India. Anthropometric data was obtained for height in centimetres and weight in kilograms. A pretested questionnaire was used to capture quantitative data. Venous blood samples were collected where red blood cell (RBC), serum folate and serum Vitamin D concentrations were measured. Anaemia was defined as normal, mild, moderate and severe as Hb > 12gm/dl, 11–11.9 gm/dl, 8–10.9 gm/dl and < 8 gm/dl respectively. Serum folate deficiency was defined as serum folate < 7 nmol/l, and RBC folate deficiency and insufficiency were defined as RBC folate < 305 nmol/l and & < 748 nmol/l, respectively. Vitamin D deficiency, insufficiency and sufficiency was defined as 25(OH)D < 20 ng/ml, 20–29 ng/ml and ≥ 30 ng/ml respectively. Descriptive statistics and inferential statistics were used. Results Almost 46% of adolescents were malnourished (10.4% were underweight, 35.4% were overweight or obese) and mean BMI was 19.7 kg/meter2 however it did not differ significantly across gender. As compared to boys more girls were vegetarian by diet. The mean concentrations for Hb, serum folate and RBC folate were 12.7 (95% CI: 12.4, 13.0) gm/dl, 15.1 (95% CI 12.5, 17.7) nmol/L and 492.9 (95% CI 431.9, 553.9) nmol/L, respectively. Mean concentration for Hb was significantly different across gender (p – 0.0). Around 17% of adolescents were anaemic, 60% were deficient for serum folate and 79% were deficient for RBC folate. Mean serum vitamin D levels were 18 ng/dl (95% CI: 17.0, 22.3) no significant difference found across gender. A total of 62.5% were deficient and 28% were insufficient for vitamin D (ng/ml). Around 50% of the adolescents lack adequate sleep (<8 hours) and increase vitamin D levels were associated with increase sleep duration (r-0.02, p-0.02). Conclusions The nutritional status of adolescents in this study is poor and reflects a need to conduct a community-based study which can help in planning strategies to improve nutritional status during critical period of adolescence Funding Sources nil.

Background: Low vitamin D levels are common in patients with foot and ankle disorders. We have previously demonstrated that juveniles diagnosed with osteochondritis dissecans (OCD) have a high prevalence of vitamin D deficiency. Moreover, there is evidence that OCD might be related to vitamin D deficiency in general. However, whether or not hypovitaminosis D is associated with OCD of the talus has yet to be elucidated. Methods: The aim of this study was to determine serum vitamin D levels [25(OH)D] of patients diagnosed with traumatic and idiopathic OCD of the talus. The vitamin D status of patients was measured and correlated to age, sex, season, etiology, laterality, degree of disease, and nicotine abuse. Moreover, parathyroid hormone and serum calcium levels of patients were obtained to assess for severe vitamin D deficiency and secondary hyperparathyroidism. Between January 2015 and December 2017, 65 patients with a mean age of 38.9 years and a total of 68 lesions were identified. Results: In total, 75.4% of patients had low vitamin D levels with a mean overall 25(OH)D level of 24.2 ng/mL. Specifically, 35.4% of patients were vitamin D deficient; another 40% were vitamin D insufficient, and only 24.6% of patients presented with sufficient vitamin D levels. Statistical analysis showed no significant difference comparing vitamin D levels of patients with idiopathic OCD to patients with traumatic OCD. Conclusion: We could not find any significant differences in the vitamin D status of patients with OCD of the talus compared with patients with foot and ankle disorders in general. However, we found that vitamin D deficiency was frequent in patients presenting with traumatic and idiopathic OCD of the talus. We believe it might be beneficial to routinely assess and treat the vitamin D status of patients. Level of Evidence: Level III, retrospective comparative study.

Abstract. Critically ill patients in intensive care units (ICUs) are exposed to various risk factors for vitamin D deficiency. Vitamin D deficiency in extended-stay patients may result in decreased muscle mass and increased fat tissue, which may impair rehabilitation and recovery. Our study aimed to evaluate the degree of serum vitamin D deficiency in critically ill surgical patients and its association with clinical outcomes. Clinical data from 186 adult male (n = 121; 65.1%) and female (n = 65; 34.9%) patients hospitalized in surgical ICUs at Ajou University Hospital from April 2015 to September 2016 were retrospectively analyzed. All adult surgical patients between the age of 18 and 88 years were enrolled. The mean serum 25-hydroxyvitamin D (25[OH]D) level of all patients was 17.8 ng/mL. A total of 120 patients (64.5%) with serum 25(OH)D levels < 20 ng/mL were classified as the deficiency group. A prolonged hospital stay was observed among the deficiency group but was not statistically significant ( p = 0.824). Serum 25(OH)D levels were significantly correlated with age but inversely correlated with Sequential Organ Failure Assessment (SOFA) score, selenium, triglyceride, and C-reactive protein levels. There was no significant difference in mortality rates between the group with a vitamin D injection and the group without a vitamin D injection (14.6% vs. 16.9%, p = 0.074). Vitamin D deficiency was common in surgical ICU patients; however, vitamin D levels were higher in older patients. In conclusion, vitamin D deficiency was inversely associated with the SOFA severity score (Correlation Coefficient –0.165, p = 0.024) but was not associated with the length of hospital or ICU stay and mortality.

Despite the abundant sunlight, vitamin D deficiency is prevalent in South Asian countries including Bangladesh. Information on vitamin D level is insufficient in adults particularly in female garment workers in Bangladesh. This study was designed to evaluate the status of vitamin D, parathormone (PTH), calcium, and alkaline phosphatase (ALP) among the female garment workers in Bangladesh. Blood samples were collected from female garment workers (n=40, case group) and general female workers (n=40, control group) in Dhaka. Serum vitamin D, PTH, calcium, and ALP were measured by chemiluminescence microparticle immunoassay. The mean level of vitamin D was significantly (p<0.001) lower in case (14.2±2.6 ng/mL) than in the control (22.4±2.4 ng/mL) group. No significant difference was found at mean of PTH and calcium between case (33.9±17.2 pg/mL;9.1±0.6 mg/dL, resp.) and control (35.9±16.3 pg/mL;9.3±0.6 mg/dL, resp.) group. The mean ALP in case (117.2±14.4 U/L) group was significantly (p<0.001) higher than the control group (80.5±30.6 U/L). Overall, PTH level did not show significant correlation with vitamin D. However, calcium and ALP levels showed a significant positive (p<0.05) and negative (p<0.001) correlation with vitamin D, respectively. This study indicates a high prevalence of vitamin D deficiency in the female garment workers in Bangladesh.

Introduction. Recent research has shown conflicting evidence on the connection between vitamin D deficiency and community-acquired pneumonia (CAP) in children. Thus, we hypothesized that vitamin D deficiency could be a risk factor for CAP. Methods. Hospitalized children between 2 and 60 months with physician-diagnosed, radiologically confirmed severe community-acquired pneumonia (CAP) were enrolled as cases. Age-matched controls were enrolled from immunization and weighing clinics. A blood sample was collected to assess serum 25-(OH)D concentration. Unconditional logistic regression was done to examine the independent association of vitamin D level with community-acquired pneumonia. Results. Seventy-four children (females: 68%) were included. Overall, 27% had vitamin D deficiency (<20 ng/mL) and 37.8% had insufficiency (20–29 ng/mL). The vitamin D level ranged from 8.67 to 46.2 ng/mL. There was no statistically significant difference in 25(OH)D levels in controls and cases ( p = 0.694 ). In unconditional logistic regression, 25(OH)D concentration was not a determinant of CAP (OR: 0.99, CI: 0.937–1.044, p = 0.689 ). This lack of association remained after adjustment for age, gender, income, crowding, and exposure to passive smoke (OR: 0.99, CI: 0.937–1.065, p = 0.973 ). Household income was significantly associated with CAP (OR: 0.11, 95% CI: 0.021–0.567, p = 0.008 ). Conclusion. Two-thirds of the children with CAP had vitamin D deficiency/insufficiency. In comparison with healthy controls, vitamin D level was not a significant determinant of community-acquired pneumonia. It informs that further multisite research is required using more rigorous scientific methods for conclusive evidence on the relationship between vitamin D and CAP.

Objective: The objective of this study is to investigate the association between Vitamin D level and psoriasis, in particular in our city of the long, hot, and sunny weather, in an attempt to add a clarification to this controversial subject. Methods: A case–control study included 120 patients with psoriasis and 38 patients with psoriatic arthritis (PsA); 89 (56.3%) patients were male. Psoriasis area and severity index (PASI) was calculated for all patients with psoriasis and disease activity score using 28 joints (DAS28) and erythrocyte sedimentation rate (DAS28) was measured for all patients with PsA. The control group comprised 164 age- and sex-matched participants (91 males and 73 females). Vitamin D serum level was performed for both patients and controls. Results: Vitamin D levels in both patients and controls were 17.4±7.7 and 28.3±5.6, respectively. The level of Vitamin D was lower in a patient with disease duration equal and more than 10 years than those with a disease duration <10 years. There is no significant difference in Vitamin D levels between the two patient subgroups. Lower Vitamin D levels were associated with high PASI and high DAS28 in psoriasis and PsA, respectively. Conclusion: Patients with psoriasis and PsA associated with low levels of serum Vitamin D. Vitamin D deficiency was found to be associated with long disease duration in both psoriasis and PsA. Patients with active disease have lower Vitamin D levels.
