Abstract   Vitamin D (VD) is important for the development and maintenance of bone tissue. This study used clinical and radiographic evaluations to analyze whether insufficient VD levels affect the periimplant health of patients with implant-supported prostheses. Data were collected for 33 patients with implant-supported prostheses: probing depth (PD); width of keratinized mucosa (wKM); bleeding index (mBI); periimplant plaque index (mPI); distance from implant to bone crest and VD level using chemiluminescence. After 1 year of implant-supported prosthesis installation, patients with levels under 30 ng/ml at baseline received 50000 IU of VD per week for 8 weeks (post treatment, PT), when clinical and radiographic evaluations were repeated for the control (n=19) and the VD (n=14) groups. Clinical and radiographic results were compared at baseline and at PT.  There were differences in PD (p=0.0247) and distance from implant to bone crest (p<0.0001), but there were not statistically different after supplementation.  wMK, mBI and mPI were not statistically different between groups.  VD levels were 24.95 ± 0.96 ng/mL in the VD group (42.42% of patients), whereas 57.57% of all participants had a mean VD value of 40.99 ± 1.23 ng/mL, a statistically significant difference (p = 0.0034). According to clinical and radiographic findings, VD serum levels do not seem to affect periimplant health. Keywords: Bone Density. Clinical Study.

Este estudo clínico e radiográfico avaliou a reposição dos níveis de vitamina D na saúde periimplantar de pacientes com próteses implantossuportadas. Profundidade bolsa a sondagem (PS), largura da mucosa queratinizada (LMQ), sangramento a sondagem (mBI), presença de placa bacteriana (mPI), distância entre implante e cristas ósseas e dosagem de VD utilizando o teste de quimioluminescência, foram medidos em 33 pacientes. Pacientes com dosagens acima de 30 ng/ml foram classificados como suficientes de VD (grupo controle, n = 19). Pacientes com menos de 30ng/ml (grupo VD, n = 14) receberam, após 1 ano da instalação da prótese sobre implante, reposição de 50.000 UI por semana durante 8 semanas, quando os exames foram repetidos. Dados iniciais intragrupos, bem como dados iniciais e pós-tratamento (PT) intergrupos e intragrupos, foram comparados. Diferenças estatísticas foram encontradas em PS (p=0.0247) e distância entre crista óssea e implante (p<0.0001) entre os grupos, mas não após reposição. Não houve diferença em LMQ, mBI e mPI entre os grupos. O valor médio de VD do grupo VD foi 24,95±0.96 ng/ml para 42,42% dos pacientes, enquanto 57,57% da amostra apresentaram valor médio de 40,99±1.23 ng/ml, demonstrando diferença estatística (p=0.0034). A reposição de VD não parece influenciar os achados clínicos e radiográficos da saúde periimplantar. Palavras-chave: Densidade Óssea. Estudo Clínico. Implantação Dentária.

9097 Background: Fatigue is one of the most common symptoms of patients diagnosed with cancer. Vitamin D deficiency has been associated with an increased risk of mortality in oncology patients. We conducted a prospective vitamin D (cholecalciferol) supplementation study to analyse the response to oral D3 supplementation on fatigue in this population of chemo-naïve patients. Methods: Eligibility critera included life expectancy ≥ 6 months, ECOG PS 0-3, low serum 25-hydroxyvitamin D3 at the time of diagnosis (using cutoff value of 32 ng/mL), and normal serum calcium level. Cancer related fatigue was measured with the Functional Assessment of Cancer Therapy Fatigue module (FACT-F). Patients were randomized to receive oral supplementation with 2,000 IU of Vitamin D3 daily for 3 months with standard cancer treatment or to continue standard treatment without vit D3 supplementation. Primary endpoint was changes in the FACT-F scale. Secondary endpoints was improvement of vitamin D serum levels and safety. Results: 69 vit D deficient patients enrolled in the this study between November 2009 and November 2011 returned a baseline FACT-F. The mean serum 25(OH)D levels were 18.7 ng/ml (SD = 7.4) at baseline. Patients in experimental arm showed marked improvement from baseline in fatigue (p<0.05) and vitamin D serum levels after 3 months (p<0.001). There were significant difference in fatigue score in patients with experimental arm and control arm after 3 months of treatment (p< 0.001). Conclusions: Vitamin D supplementation resulted in a significant increase in Fatigue score and serum 25(OH)D levels in vitamin D deficient patients. Fatigue improve rapidly but remain worse in control arm. The safety profile of vitamin D in combination with chemotherapy or BSC was acceptable. [Table: see text]

The aim of our study was to evaluate the effects of vitamin D supplementation on circulating levels of magnesium and selenium in patients with type 2 diabetes mellitus (T2DM). A total of 126 adult Saudi patients (55 men and 71 women, mean age 53.6 ± 10.7 years) with controlled T2DM were randomly recruited for the study. All subjects were given vitamin D3 tablets (2000 IU/day) for six months. Follow-up mean concentrations of serum 25-hydroxyvitamin D [25-(OH) vitamin D] significantly increased in both men (34.1 ± 12.4 to 57.8 ± 17.0 nmol/L) and women (35.7 ± 13.5 to 60.1 ± 18.5 nmol/L, p < 0.001), while levels of parathyroid hormone (PTH) decreased significantly in both men (1.6 ± 0.17 to 0.96 ± 0.10 pmol/L, p = 0.003) and women (1.6 ± 0.17 to 1.0 ± 0.14 pmol/L, p = 0.02). In addition, there was a significant increase in serum levels of selenium and magnesium in men and women (p-values < 0.001 and 0.04, respectively) after follow-up. In women, a significant correlation was observed between delta change (variables at six months-variable at baseline) of serum magnesium versus high-density lipoprotein (HDL)-cholesterol (r = 0.36, p = 0.006) and fasting glucose (r = - 0.33, p = 0.01). In men, there was a significant correlation between serum selenium and triglycerides (r = 0.32, p = 0.04). Vitamin D supplementation improves serum concentrations of magnesium and selenium in a gender-dependent manner, which in turn could affect several cardiometabolic parameters such as glucose and lipids.

AbstractPatients afflicted with melanoma show lower vitamin D serum levels (VDSL) than the healthy population. This hypothesis agrees with its well-known antiproliferative features. An observational study was carried out to collect VDSL in patients suffering from melanoma. Our aim was to identify a potential connection between low VDSL and the risk to incur melanoma. Furthermore, we studied the association between VDSL at the diagnosis of melanoma and other germane prognostic factors. The population held in regard was composed of 154 patients with a diagnosis of melanoma between 2016 and 2019. These patients were retrospectively collected from our follow-up storage. We compared VDSL to clinical and pathological parameters (age, sex, tumour location, Breslow’s depth, Clark’s level, histological subtype, ulceration, et aliqua). Moreover, we recruited a control group with negative melanoma history. Mean and median of VDSL were significantly lower in the melanoma group. Instead, we found a negative association between melanoma and VDSL > 30 ng/L (OR 0.11; p < 0.0001). No correlation between VDSL and both Breslow’s depth and Clark’s level was discovered, but the VDSL comparison between thin (depth ≤ 1 mm) and thick tumours (depth > 1 mm) revealed a statistically significant difference (21.1 ± 8.2 ng/L vs 17.8 ± 8.1; p = 0.01). Moreover, VDSL were significantly lower in melanomas with mitotic rate ≥ 1/mm2 (22.1 ± 8.3 ng/L; p < 0007). Nevertheless, no connection was found between VDSL and both ulceration and positive sentinel nodes (p = 0.76; p = 0.74). Besides, our study revealed no association between VDSL and histological subtype (p = 0.161). Lower VDSL correlate with thick and high mitotic rate tumours. Future prospective studies would investigate if appropriate upkeep of suitable VDSL can decrease the risk of primary and recurrent melanoma diagnosis.

Background : Low level of vitamin D impact the disease activity and the degree of fatigue in SLE patients. This study aims to determine the effect of vitamin D supplementation on disease activity and fatigue condition in Systemic Lupus Erythematosus (SLE) patients with hipovitamin D.Methods: We performed an open clinical trial. Subjects were randomized into two different groups (supplementation or placebo) using simple random sampling. The treatment group got vitamin D3 softgel/ cholecalciferol 1200 IU/day or 30 mg/day, while the control group gotplacebo for 3 months. SLEDAI scores and FSS scores were calculated at pre and posttreatment.Results: There were 20 subjectsfor supplementation group and 19 subjects in the placebo group. From this study, before and after treatment, we found a significant difference of mean level of vitamin D in supplementation group (p=0.000), and no significant difference inpatients with placebo (p=0.427). Moreover, from the SLEDAI score analysis, observed a significant difference bothin the supplemented group (p=0.000) and the placebo group (p=0.006). FSS scores significantly different in the supplemented group (p=0.000). Incorrelation test,there was a negative correlation (r=-0763) between vitamin D level and disease activity (SLEDAI), and both showing stastistical significance between thepre supplementation (p=0.000) and post supplementation (r=-0846; p=0.000). Similarly to theFSS scores, there was a meaningfulnegative correlation (r=-0.931, p=0.000) between the level of vitamin D with FSS scores pre and post supplementation (r=-0.911; p= 0.000). Furthermore, there was a significant correlation between disease activity (SLEDAI) pre supplementation with fatigue condition pre supplementation (r=0.846; p = 0.000) and postsupplementation (r=0.913; p= 0.000).Conclusion: The supplementation of vitamin D 1200 IU per day in patients with SLE improve disease activity and degree of fatigue.

Background: Tooth extraction can cause alveolar resorption, and will reduce the denture retention. The process of bone resorption looks like the process of osteoporosis. Calcium and vitamin D supplementation is the rational therapy for minimizing bone loss. Miacalcic is the drug of choice for osteporotic patient. Purpose: This study is aimed to know whether the combination of miacalcic, calcium lactate, and vitamin C are effective in inhibiting post extracted alveolar resorption. Methods: Thirty three healthy postmenopausal women were chosen as samples and they were classified randomly into control group (without treatment), 1st experiment group (treatment was started 3 months post extraction), and 2nd experiment group (treatment was started at the 2nd day post extraction). The treatment was done by giving miacalcic nasal spray, calcium lactate 500 mg and vitamin C 100 mg tablets every morning in 10 days every month for 3 months. X-ray photo of the post extracted area were taken an hour, 3 months, and 6 months post-extraction. Results: After 6 month, there was significant difference in buccolingual thickness decreasing among three groups (p<0.05). The maximum mean difference of buccolingual thickness decreasing was 0.72 mm, between control and 2nd experiment groups. There was no significant difference about decreasing bone density among them (p>0.10). The maximum difference of the mean of density decreasing was 1,906 g/cm2/mm between control and 2nd experiment groups. The increasing density mostly occurred in the 2nd experiment group. Conclusion: The combination of miacalcic, calcium lactate, and vitamin C are effective for inhibiting alveolar resorption, although statistically there was no significant difference about bone density decreasing. The sooner this treatment is given the better result will be achieved.Latar belakang: Pencabutan gigi menyebabkan resorpsi tulang alveolaris, dan akan mengurangi retensi geligi tiruan. Proses resorpsi tulang alveol pada osteoporosis mirip dengan proses resorpsi tulang pada penyembuhan luka bekas pencabutan. Miacalcic adalah obat utama untuk penderita osteoporosis. Kalsium dan vitamin D merupakan terapi yang rasional untuk meminimalkan resorpsi tulang. tujuan: Membuktikan apakah kombinasi miacalcic, kalsium laktat, and vitamin C juga efektif menghambat resorpsi tulang alveol pasca pencabutan. Metode: Sampel 33 wanita postmenopause yang sehat, terbagi secara acak ke dalam kelompok kontrol (tanpa perlakuan), kelompok eksperimen 1 (perlakuan mulai 3 bulan pasca pencabutan) dan kelompok eksperimen 2 (perlakuan mulai hari kedua pasca pencabutan). Perlakuannya yaitu: pemberian miacalcic semprot hidung, tablet kalsium laktat 500 mg dan vitamin C 100 mg setiap pagi, 10 hari dalam sebulan, selama tiga bulan. Foto sinar-X dari regio pasca pencabutan dibuat satu jam, 3 bulan, dan 6 bulan pasca pencabutan. Hasil: 6 bulan pasca-cabut, ada beda bermakna perihal selisih tebal bukolingual tulang alveol antar ketiga kelompok (p<0,05). Rerata penurunan ketebalan ini maksimal sebanyak 0.72 mm, antara kelompok kontrol dan kelompok eksperimen 2. Penurunan kepadatan tulang antar ketiga kelompok tidak bermakna (p>0,10). Beda maksimum rerata kepadatan tulang antara kelompok kontrol dan kelompok eksperimen 2 sebesar 1,906 g/cm2/mm. Peningkatan kepadatan terbanyak dialami anggota kelompok eksperimen 2. Kesimpulan: Kombinasi miacalcic, kalsium laktat, vitamin C efektif menghambat resorpsi tulang alveolaris, walaupun secara statistik beda penurunan kepadatan tidak bermakna. Makin awal pemberian perlakuan, hasilnya akan lebih baik.

Vitamin D inadequacy is pervasive in the oldest-old. Many vitamin D metabolites are available for supplementation, their effects on the recovery of adequate serum levels remain unknown. We investigate the effects of supplementation with cholecalciferol (D3) and calcifediol (25D3) on serum levels of 25(OH)D, 1-25(OH)D, bone and inflammatory markers, ultimately identifying clinical predictors of successful treatment. Sixty-seven oldest-old individuals were randomized to weekly administration of 150 mcg of 25D3 or D3, from hospital admission to 7 months after discharge. Supplementation of 25D3 and D3 were associated with increasing serum levels of 25(OH)D (p < 0.001) and 1-25(OH)D (p = 0.01). Participants on 25D3 experienced a steeper rise than those on D3 (group*time interaction p = 0.01), after adjustment for intact parathyroid hormone (iPTH) levels the differences disappeared (intervention*iPTH interaction p = 0.04). Vitamin D supplementation was associated with a decreasing trend of iPTH and C-reactive protein (CRP) (p < 0.001). Polypharmacy and low handgrip strength were predictors of failure of intervention, independent of vitamin D metabolites. In conclusion, D3 and 25D3 supplementation significantly increase vitamin D serum levels in the oldest-old individuals, with a tendency of 25D3 to show a faster recovery of acceptable iPTH levels than D3. Polypharmacy and low muscle strength weaken the recovery of adequate vitamin D serum levels.

Abstract Background Vitamin D deficiency is frequently present in inflammatory bowel disease (IBD) with a higher incidence in Crohn’s disease (CD) than in ulcerative colitis (UC). Given the involvement of the alimentary tract, many factors can contribute to vitamin D deficiency. The aim of the study was to investigate the association of vitamin D deficiency according to body mass index (BMI) in adult patients with IBD. Methods A cross-sectional study was conducted on a cohort of 152 IBD patients, 68.1% (n = 104) CD and 31.9% (n = 48) UC. The mean age of the total study population was 37.3±11.8 years and 57.3% (n = 87) were male. All patients were adult, Caucasian and without vitamin D supplementation. Patients were recruited during one year period. Results Out of all IBD patients, 60.5% (n = 92) had vitamin D deficiency, 32.2%, (n = 49) insufficiency and 7.2% (n = 11) sufficiency. According to BMI categories there were 12.5% (n = 19) obese patients, 27.6% (n = 42) overweight, 51.3% (n = 78) with normal body weight, and 8.6% (n = 13) underweight. There was a significant difference in vitamin D levels according to different BMI categories in terms of underweight patients having the lowest vitamin D levels; underweight 29.84±11.94 mmol/l, normal 46 ± 20.7 mmol/l, overweight 48±20.1 mmol/l, obese 51±15.3 mmol/l. In addition, there was a significant correlation of vitamin D levels and BMI values (Rho = 0.212, 95% CI 0.069–0.345, p = 0.004), which was more clearly observed in the lower range of BMI values (Figure 1). Male underweight patients had lower levels of vitamin D compared with female patients (26.6 ± 9 vs. 34.7 ± 5.6, p &lt; 0.05). Both patients with CD and UC had significant positive correlation of vitamin D levels and BMI values (UC Rho=0.40, 95% CI 0.16–0.59, p = 0.001, UC Rho = 0.27, 95% CI 0.01–0.05, p = 0.044). However, when comparing vitamin D levels according to phenotype, a significant difference in vitamin D levels was observed in underweight CD (28.4 ± 11.1) comparing to underweight UC patients (40.6 ± 10.6), p &lt; 0.05. In logistic regression analysis, CD phenotype was risk factor for vitamin D deficiency (OR 2.18 95% CI 1.01–4.72, β = 1.22, p = 0.04). Conclusion Our results on untreated IBD patients show a high proportion of vitamin D deficiency both in CD and UC, and significant correlation of vitamin D levels and BMI values, especially in the lower range of BMI values. Moreover, underweight CD patients have lower vitamin D levels comparing to UC. This suggests the need for regular vitamin D monitoring and supplementation especially in IBD patients at risk.

AbstractVitamin D (vitD) deficiency is the most common nutritional deficiency worldwide. Most patients are treated with oral vitD capsules (either vitD2 or vitD3). A few studies have reported equal efficacy of buccal spray vitD. This is a new formulation that is absorbed via the oral mucosa into the systemic circulation, bypassing the gastrointestinal route. The main objective of this systematic review was to identify RCT evidence for the comparative effectiveness of buccal spray versus oral vitD on serum 25-hydroxyvitaminD [25-OHD] concentrations and any adverse effects of buccal spray vitD. We have published an a priori protocol using Joanna Briggs Institute (JBI) methodology (PROSPERO CRD42018118580). A three-step search strategy to identify RCTs was conducted, which reported serum 25-OHD concentrations from five databases from 2008–2018. Retrieved abstracts were screened; included papers imported into JBI SUMARI and assessed for study quality (GRADE) by two authors. Meta-analysis was planned. Three RCTs met our inclusion criteria. Due to heterogeneity of studies, meta-analysis was not possible. In a RCT crossover study, mean serum 25-OHD concentrations were significantly higher in patients with malabsorption syndrome (n = 20) on 1000IU buccal spray + 117.8%(10.46, 95%CI6.89,14.03ng/ml) vs.1000IU oral vitD3 + 36.02%(3.96, 95%CI2.37, 5.56ng/ml) at 30days (p < 0.0001). Mean serum 25-OHD were also significantly higher in healthy adults (n = 20) on buccal spray + 42.99%(7.995, 95%CI6.86,9.13ng/ml)vs.oral vitD3 + 21.72%(4.06, 95%CI3.41,4.71ng/ml) at 30days (p < 0.0001). In another RCT crossover study, ANCOVA revealed no significant difference in the mean and SD change from baseline total 25-OHD concentrations in adults (n = 22) on 3000IU buccal spray vs. 3000IU oral vitD3 + 44%,26.15 (SD17.85) vs. + 51%,30.38 (SD17.91)nmol/l, respectively;F = 1.044, adjusted r20.493,p = 0.313 at 4 weeks. In a RCT, 800IU buccal spray was equally effective as 750IU oral vitD3 in children with neurodisabilities(n = 24) at 3 months. Both groups had a significant increase in 25-OHD; 11.5 ng/ml(median8–19) to 26.5(13.6–39)ng/ml and 15.5ng/ml(8–20) to 34.5(22–49)ng/ml, respectively (z = 150;p < 0.0001). The overall certainty of evidence was very low to moderate. No adverse effects were reported. The evidence from these studies suggests that 800IU-3000IU doses of buccal spray vitD3 given daily may be an effective alternative as oral vitD3 in obtaining short-term haematological responses in serum 25-OHD concentrations. Buccal spray vitD3 may be a useful alternative for patients with intestinal malabsorption or dysphagia. Future research should compare buccal spray VD3 to intramuscular injections and confirm these findings in well-designed trials.

Abstract Premenstrual syndrome (PMS) is a common disorder in the reproductive age that negatively significant impacts on women’s quality of life. This randomized clinical trial study was undertaken to investigate the effect of vitamin D supplementation on inflammatory and antioxidant markers in 44 vitamin D deficient (25(OH)D < 20 ng/mL) students with PMS. Participants received either 50,000 IU vitamin D3 or a placebo pearl fortnightly for 4 months. At the baseline and in the last 2 months of intervention, participants were asked to complete the PMS Daily Symptoms Rating form along with taking the pearls and their blood samples were collected to assess serum levels of 25(OH)D3, Interleukin10 and 12 (IL-10, IL-12) and total antioxidant capacity (TAC). In vitamin D group, serum levels of IL-10 and IL-12 significantly decreased while TAC significantly increased post-intervention. There were significant differences regarding serum IL-12 and TAC levels between the two groups. Mean score of the total PMS symptoms showed significant improvement in 25(OH)D. Vitamin D supplementation seems to be an effective strategy to improve inflammation and antioxidant markers in vitamin D deficient women with PMS. This clinical trial was registered at Iranian Registry of Clinical Trials on 20/06/2018 (IRCT20180525039822N1).
