Background and Objectives: Pneumonia is the inflammation of parenchyma of lungs. It strictly represents any inflammatory condition that involves the lungs along with the visceral pleura, airways, alveoli, connective tissues and vascular structures. The objective of the study was to see the efficacy of vitamin D in children with pneumonia.Material and Methods: A randomized control study was conducted in Department of Pediatric Medicine, Mayo Hospital, Lahore, Pakistan. One hundred patients with pneumonia received vitamin D along with appropriate antibiotics and one hundred were treated with antibiotics but without vitamin D. The patients were discharged after the fast breathing and chest in drawing settled. The duration of hospital stay was noted. They were followed up for next 90 days after discharge from hospital and any new episode of pneumonia was noted and recorded.Results: The mean number of days to recovery were similar between the group receiving vitamin D (5.7 ± 2.7 days) and the group not receiving vitamin D (6.1 ± 2.8days), (p=0.28). While comparing repeat episode of pneumonia within next three months, the repeat episode of pneumonia was significantly lower in the intervention group (2%) than the group without supplementation (9%; p = 0.002) within 30 days of supplementation of vitamin D.Conclusion: Vitamin D supplementation in a single dose to the children diagnosed as pneumonia significantly reduces the occurrence of new episodes of pneumonia within one month of discharge.Janaki Medical College Journal of Medical Sciences (2015) Vol. 3 (1):5-13

AbstractThe incidence of vitamin D deficiency is high globally, and vitamin D supplementation draws particular attention. The objective of this study was to investigate the effects of stratified vitamin D supplementation in middle-aged and elderly individuals with vitamin D insufficiency in Beijing. A total of 448 subjects aged over 40 years old were selected from a community in Beijing. Among them, 100 middle-aged and elderly people with vitamin D insufficiency were randomly selected on a voluntary basis. They were further divided into control group and intervention group. The control group received health education and lifestyle guidance, and the intervention group received lifestyle guidance and vitamin D supplementation for nine months. The doses were stratified as follows: for vitamin D insufficiency, oral vitamin D3 supplement was given at 5000 IU/w; for mild vitamin D deficiency, oral vitamin D3 supplement was given at 10 000 IU/w; for severe vitamin D deficiency, oral vitamin D3 supplement was given at 15 000 IU/w. Safety evaluation was conducted after three-month treatment. The intervention group consisted of 8%, 62%, and 30% of cases who had vitamin D insufficiency, mild vitamin D deficiency, and severe vitamin D deficiency, respectively, which were similar with the control group. It showed that the blood 25(OH)D level increased significantly in the intervention group, from 14.30±4.30 ng/ml to 33.62±6.99 ng/ml (p<0.001), in contrast to insignificant change in the control group. Stratified vitamin D supplementation effectively increased the blood 25(OH)D level, as well as the number of cases with corrected vitamin D insufficiency or deficiency.

Background: Vitamin D deficiency remains the most common cause of rickets globally and is highly prevalent in developing countries including India. This study aimed to compare the efficacy of vitamin D and calcium together with calcium alone on growth parameters of children with vitamin D deficiency in community based setting.Methods: A randomized controlled trial was conducted in community based setting in Kanpur district. Multistage random sampling technique was used to select a total of 395 children between 2 years to 5 years from 5 villages of block Vidhunu. Of these, 138 children were randomized into two groups using balanced block randomization technique. Group 1 received vitamin D with calcium together and group 2 received calcium alone for a period of 12 months. Anthropometry, serum vitamin D, calcium, alkaline phosphatase levels were estimated at baseline and after 12 months. Data was analyzed using SPSS 20. Student’s t test was used to analyze the differences in growth and laboratory parameters in the two groups. Multiple linear regression analysis was used to assess the effect of various factors on the growth parameters.Results: Prevalence of vitamin D deficiency was 78.7%. Baseline characteristics of both groups were similar. After 12 months, group 1 demonstrated significantly greater improvement in weight SD score (21.4%) and height SD score (10.3%) and growth velocity (9.1 cm/year) compared to group 2 (14.3%, 7.8% and 6.9 cm/ year respectively). Also subjects in group 1 showed significantly greater improvement in serum levels of vitamin D, calcium and alkaline phosphatase than group 2.Conclusions: Vitamin D supplementation along with calcium improves the growth of children. Regular supplementation of all children with vitamin D can be considered as a policy for prevention of malnutrition.

Vitamin D deficiency has been correlated with the infertility and lower clinical pregnancy following IVF. Anti-Mullerian hormone (AMH) plays a key role during follicle development; it has been recognised as a predictor of regular ovulation and probably IVF success. Considering the critical need for experimental human study to investigate the impact of vitamin D supplementation on ovulatory function, the aim of this study was to demonstrate the effectiveness of the vitamin D supplementation on AMH serum levels among reproductive-age women with vitamin D deficiency. 195 reproductive women (18–35 year-old) with confirmed vitamin D deficiency [serum 25(OH)D <75 nmol L–1] and without diagnosed polycystic ovary syndrome (PCOS) were enrolled to this controlled clinical trial. Participants were randomly assigned to a control group (n = 96) or an intervention group (n = 99). Women in the intervention group used 2000 IU day–1 vitamin D drops for 15 weeks. 19 participants were missed during the follow-up; finally the numbers of women in the intervention and control groups were 91 and 85, respectively. At the beginning of the study and after the intervention, 25-hydroxyvitamin D and AMH serum levels were quantified using enzyme immunoassay (EIA; Immunodiagnostic Systems, Boldon, UK) and ELISA (Beckman-Coulter Inc., Fullerton, CA, USA) methods respectively. The post-intervention AMH measurement was performed after 2–5 weeks in the same day-of-cycle on which basal AMH measurement was done. Paired t-test, independent t-test, and Pearson correlation were used as appropriate and a P-value of less than 0.05 was considered significant. Significantly low AMH levels were seen in the vitamin D deficient women of this study (14.46 ± 11.92 pmol L–1 in control group and 14.09 ± 11.52 pmol L–1 in intervention group). After the intake of vitamin D supplementation in intervention group, AMH levels were increased to 24.89 ± 12.47 pmol L–1, which were significantly different from the 15.43 ± 13.03 pmol L–1 in control group (P < 0.001). Correlation coefficients for AMH with pre-intervention and post-intervention vitamin D were r = 0.489 and r = 0.599 respectively (P < 0.001). Treatment of vitamin D deficiency increases AMH to the optimum levels. Vitamin D deficient women had low levels of AMH. These findings support other studies which found a correlation of poor IVF outcomes with low vitamin D levels. Vitamin D supplementation could be useful in the improvement of controlled ovarian hyper-stimulation/IVF outcomes in case of vitamin D deficiency.

BackgroundVitamin D has an immunomodulatory role but the effect of therapeutic vitamin D supplementation in SARS-CoV-2 infection is not known.AimEffect of high dose, oral cholecalciferol supplementation on SARS-CoV-2 viral clearance.DesignRandomised, placebo-controlled.ParticipantsAsymptomatic or mildly symptomatic SARS-CoV-2 RNA positive vitamin D deficient (25(OH)D<20 ng/ml) individuals.InterventionParticipants were randomised to receive daily 60 000 IU of cholecalciferol (oral nano-liquid droplets) for 7 days with therapeutic target 25(OH)D>50 ng/ml (intervention group) or placebo (control group). Patients requiring invasive ventilation or with significant comorbidities were excluded. 25(OH)D levels were assessed at day 7, and cholecalciferol supplementation was continued for those with 25(OH)D <50 ng/ml in the intervention arm. SARS-CoV-2 RNA and inflammatory markers fibrinogen, D-dimer, procalcitonin and (CRP), ferritin were measured periodically.Outcome measureProportion of patients with SARS-CoV-2 RNA negative before day-21 and change in inflammatory markers.ResultsForty SARS-CoV-2 RNA positive individuals were randomised to intervention (n=16) or control (n=24) group. Baseline serum 25(OH)D was 8.6 (7.1 to 13.1) and 9.54 (8.1 to 12.5) ng/ml (p=0.730), in the intervention and control group, respectively. 10 out of 16 patients could achieve 25(OH)D>50 ng/ml by day-7 and another two by day-14 [day-14 25(OH)D levels 51.7 (48.9 to 59.5) ng/ml and 15.2 (12.7 to 19.5) ng/ml (p<0.001) in intervention and control group, respectively]. 10 (62.5%) participants in the intervention group and 5 (20.8%) participants in the control arm (p<0.018) became SARS-CoV-2 RNA negative. Fibrinogen levels significantly decreased with cholecalciferol supplementation (intergroup difference 0.70 ng/ml; P=0.007) unlike other inflammatory biomarkers.ConclusionGreater proportion of vitamin D-deficient individuals with SARS-CoV-2 infection turned SARS-CoV-2 RNA negative with a significant decrease in fibrinogen on high-dose cholecalciferol supplementation.Trial register numberNCT04459247.

BackgroundThe relationship between asthma and vitamin D deficiency has been known for some time. However, interventional studies conducted in this regard have shown conflicting results.ObjectiveTo evaluate the efficacy of vitamin D supplementation in asthmatic patients in improving the degree of control of asthma.MethodsRandomised, triple-blind, placebo-controlled, parallel-group study in adult asthmatic patients with serum 25-hydroxyvitamin-D3 <30 ng/mL. The intervention group received oral supplementation with 16 000 IU of calcifediol per week, and the control group had placebo added to their usual asthma treatment. The study period was 6 months. The primary endpoint was the degree of asthma control as determined by the asthma control test (ACT). Secondary endpoints included quality of life measured using the mini Asthma Quality of Life Questionnaire, the number of asthma attacks, oral corticosteroid cycles, the dose of inhaled corticosteroids, number of emergency visits, unscheduled consultations with the primary care physician and hospitalisations for asthma.ResultsOne hundred and twelve patients were randomised (mean age 55 years, with 87 (78%) being women). Of the 112 patients, 106 (95%) completed the trial. Half the patients (56) were assigned to the intervention group and the other half to the control group. A statistically significant clinical improvement was observed in the intervention group (+3.09) compared with the control group (−0.57) (difference 3.66 (95% CI 0.89 to 5.43); p<0.001) as measured using ACT scores. Among the secondary endpoints, a significant improvement in the quality of life was found in the intervention group (5.34), compared with the control group (4.64) (difference 0.7 (95% CI 0.15 to 1.25); p=0.01).ConclusionAmong adults with asthma and vitamin D deficiency, supplementation with weekly oral calcifediol compared with placebo improved asthma control over 6 months. Further research is needed to assess long-term efficacy and safety.Trial registration numberNCT02805907.

Hypovitaminosis D is common in India. In the present prospective partially randomised study of vitamin D (D3) supplementation during pregnancy, subjects were randomised in the second trimester to receive either one oral dose of 1500 μg vitamin D3(group 1,n48) or two doses of 3000 μg vitamin D3each in the second and third trimesters (group 2,n49). Maternal 25-hydroxyvitamin D (25(OH)D) at term, cord blood (CB) alkaline phosphatase (ALP), neonatal serum Ca and anthropometry were measured in these subjects and in forty-three non-supplemented mother–infant pairs (usual care). Median maternal 25(OH)D at term was higher in group 2 (58·7, interquartile range (IQR) 38·4–89·4 nmol/l)v. group 1 (26·2, IQR 17·7–57·7 nmol/l) and usual-care group (39·2, IQR 21·2–73·4 nmol/l) (P = 0·000). CB ALP was increased (>8.02 μkat/l or >480 IU/l) in 66·7 % of the usual-care groupv. 41·9 % of group 1 and 38·9 % of group 2 (P = 0·03). Neonatal Ca and CB 25(OH)D did not differ significantly in the three groups. Birth weight, length and head circumference were greater and the anterior fontanelle was smaller in groups 1 and 2 (3·08 and 3·03 kg, 50·3 and 50·1 cm, 34·5 and 34·4 cm, 2·6 and 2·5 cm, respectively)v. usual care (2·77 kg, 49·4, 33·6, 3·3 cm;P = 0·000 for length, head circumference and fontanelle andP = 0·003 for weight). These differences were still evident at 9 months. We conclude that both 1500 μg and two doses of 3000 μg vitamin D3had a beneficial effect on infant anthropometry, the larger dose also improving CB ALP and maternal 25(OH)D.

Abstract Background Many international medical organizations recommend vitamin D supplementation for infants, especially exclusively breastfed infants. In Thailand, however, data regarding the vitamin D status in Thai infants are lacking. Such data would help to support physician decisions and guide medical practice. Methods Full-term, exclusively breastfed infants were randomized into two groups at 2 months of age to continue exclusive breastfeeding either without vitamin D supplementation (control group, n = 44) or with vitamin D3 supplementation at 400 IU/day (intervention group, n = 43) until 6 months of age. At 6 months, the serum vitamin D (25OHD) of the infants and their mothers, serum bone marker, and infants’ growth parameters were compared between the two groups. Results The infants’ serum 25OHD concentration was lower in the control group than intervention group (20.57 ± 12.66 vs. 46.01 ± 16.42 ng/mL, p < 0.01). More infants had vitamin D sufficiency (25OHD of > 20 ng/mL) in the intervention group than control group (93.0% vs. 43.2%, p < 0.01). There were no significant differences in the maternal 25OHD concentrations between the control and intervention groups (25.08 ± 7.75 vs. 23.75 ± 7.64 ng/mL, p = 0.42). Serum calcium, phosphorus, intact parathyroid hormone, alkaline phosphatase, and infants’ growth parameters were comparable between the two groups. After adjustment for the confounding factors, 25OHD concentration in the intervention group was 25.66 ng/mL higher than the control group (95% confidence interval, 19.07–32.25; p < 0.001). Vitamin D supplement contributed to an 88.7% decrease in the prevalence of vitamin D insufficiency/deficiency (relative risk, 0.11; 95% confidence interval, 0.04–0.35; p < 0.01). Conclusions Most full-term, exclusively breastfed Thai infants have serum vitamin D concentration below sufficiency level at 6 months of age. However, vitamin D supplementation (400 IU/day) improves their vitamin D status and prevents vitamin D deficiency. Trial registration The study was pre-registered in the Thai Clinical Trials Registry (TCTR20190622001) on 22/06/2019.
