Background: Vitamin D insufficiency is common in critically ill patients. It is hypothesized that vitamin D deficiency would be associated with sepsis in the critically ill. Thus, the present study aimed to investigate the association between vitamin D and sepsis severity. Method: In this cross-sectional study, patients with sepsis referring to a university hospital in Tehran, Iran, from February 2018 to March 2019 were included. Plasma concentrations of vitamin D in critically ill subjects admitted were assessed. Data were analyzed using SPSS version 20.0. P-values less than 0.05 were considered statistically significant. Results: Among the investigated patients, the mean serum level of vitamin D3 was 19.03 ± 13.08 ng/mL. The prevalence of vitamin D insufficiency in critically ill subjects with sepsis was 100% (150/150). Only sex (P = 0.01) indicated a significant association with vitamin D. Patients suffering from severe sepsis had lower levels of vitamin D compared to the patients with non-severe sepsis (P = 0.07). Conclusions: The present study showed that all critically ill patients studied had vitamin D insufficiency. In line with the biological evidence, the present study suggests that vitamin D deficiency may predispose patients to sepsis. Further studies are needed to establish the causes and mechanisms underlying these interpretations.

Background: Vitamin D insufficiency is a common global phenomenon. Its insufficiency is also reported to be common in hospitalized patients and particularly in critically ill patients. Methods: Following ethical approval, consent will be sought from either the patient or assent from a near relative. Successive patients admitted to the medical emergency and ICU at tertiary care health center who fulfill the following criteria for sepsis, within a 24 h time window, were included in the study. Results: A total of 50 patients were enrolled in the study, 37 (74.00%) were discharged whereas 13(26.00%) patients expired. The majority of patients, irrespective of outcome had Vitamin D deficiency. Although normal Vitamin D levels were observed in relatively higher proportion of patients who were discharged (29 patients) as compared to those who expired (12 patients) yet this difference was not significant statistically (P = 0.481). Conclusion: Vitamin D deficiency leads to increased risk of mortality in the critically ill patients. Keywords: Sepsis, Vitamin D deficiency, Mortality.

Vitamin D (25(OH)D) insufficiency and deficiency are highly prevalent in adult soccer players and can exceed 80% even in regions with high insolation; however, the treatment of this condition is often complicated. The aim of the present study was to examine the prevalence of vitamin D insufficiency and deficiency in youth Russian soccer players and the efficacy of its treatment. Participants were 131 young male football players (age 15.6 ± 2.4 years). Low vitamin D levels (below 30 ng/mL) were observed in 42.8% of the analyzed participants. These athletes were split in two groups composed of persons with vitamin D deficiency (serum vitamin D below 21 ng/mL) and insufficiency (serum vitamin D in range of 21–29 ng/mL). A dietary supplement of 5000 IU cholecalciferol per day was administered for two months. After the treatment, an average 92% increase in vitamin D concentration was observed (before treatment—19.7 ± 5.4 ng/mL, after treatment—34.7 ± 8.6 ng/mL, p<0.001) and 74% of the post-treatment values were within the reference range (30–60 ng/mL). Serum concentration of vitamin D increased by 200% ± 98% (p<0.001) during the first month of treatment with vitamin D deficiency and insufficiency being successfully treated in 83% of the football players. In summary, the prevalence of vitamin D insufficiency and deficiency was high in young Russian soccer players. Furthermore, it was indicated that the daily usage of cholecalciferol in a dose 5000 IU was an effective and well-tolerated treatment for vitamin D insufficiency. No linear dependency between the duration of treatment and increase in vitamin 25(OH)D concentration was observed.

Aim: This study is aimed to evaluate the relationship between serum vitamin D levels and metabolic syndrome in hemodialysis patients. Materials and Methods: This study was conducted with participation of 80 patients undergoing hemodialysis for more than 6 months three times a week, aged > 18 years. Their height, dry weight, waist circumference were measured. Biochemical parameters such as serum 25-hydroxyvitamin D, lipid profile, and fasting blood glucose were analyzed. Metabolic syndrome was defined using the National Cholesterol Education Program Adult Treatment Panel III criteria. Severe vitamin D deficiency, 25 (OH) vitamin D < 5 ng/ml; mild vitamin D deficiency, 25 (OH) vitamin D 5-15 ng/ml; vitamin D insufficiency, 25 (OH) vitamin D 16-30 ng/ml, and vitamin D sufficiency, 25 (OH) vitamin D > 30 ng/ml were categorized. Statistical analysis of the data was performed with the use of SPSS version 21.0. Results: 48.4% of hemodialysis patients were identified to have metabolic syndrome. According to the serum levels of vitamin D; 35.0% of patients had severe vitamin D deficiency, 37.4% of patients had mild vitamin D deficiency, 18.8% of patients had vitamin D insufficiency and 8.8% of patients had vitamin D sufficiency (> 30 ng/ml). Vitamin D insufficiency was significantly associated with metabolic syndrome and central obesity. Conclusions: Deficiency/insufficiency is observed in serum 25-hydroxyvitamin D levels in hemodialysis patients. Vitamin D insufficiency is associated with metabolic syndrome.

Abstract Background Premature birth is the main cause of mortality in children under 1 year, and vitamin D deficiency during gestation is associated with prematurity. The effects of vitamin D are mediated by its receptor, which is encoded by the VDR gene. VDR variants—such as single nucleotide variation (SNV)—are associated with increased risk of prematurity, but there are conflicting results. We evaluated serum vitamin D concentrations and the frequency of TaqI/A > G, BsmI/C > T, ApaI/C > A, and FokI/A > T VDR variants in mothers and preterm (PTN) and full-term (FTN) newborns. Methods We conducted a case-control study comprising 40 pairs of mothers and their PTNs (gestational age < 32 weeks and/or weight < 1500 g), and 92 pairs of mothers and FTNs as controls. Genotyping was performed by real-time PCR, and plasma vitamin D concentrations were measured by electrochemiluminescence. Results Vitamin D levels were significantly lower in PTN mothers. Genotypes TaqI/GG and BsmI/TT, and haplotypes AAG (TaqI/A-ApaI/A-FokI/G) and GCA (TaqI/G-ApaI/C-FokI/A) were significantly more frequent in PTN mothers, and genotypes TaqI/AG, ApaI/AA, and FokI/AG resulted in significantly lower vitamin D levels. Genotypes BsmI/TT and ApaI/AA were associated with vitamin D deficiency and 2.36 and 7.99 times greater likelihood of PTB, respectively. Vitamin D levels were also lower in PTNs, although it was not statistically significant. Genotypes BsmI/TT, ApaI/AA, and FokI/GG, and haplotype GAG (TaqI/G-ApaI/A-FokI/G) were significantly more frequent in PTNs. Those with FokI/GG genotypes had significantly lower vitamin D levels. Conclusions VDR variants contribute to variations in vitamin D concentrations and the increased risk of prematurity.

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.

Schizophrenic Patients

Background: Vitamin D is an immune-regulator that influences the neuro-inflammation process in schizophrenia. The study aimed to explore the vitamin D serum level in schizophrenic patients at the outpatient clinic of the Provincial Mental Hospital, West Java, Indonesia. Methods: A quantitative descriptive study was conducted in November-December 2019 using secondary data of all-male schizophrenic patients at the Provincial Mental Hospital. Data collected were demographic characteristics, clinical characteristics, and vitamin D Level. Scoring was then performed using Positive and Negative Syndrome Scale (PANSS) and Montreal Cognitive Assessment (MoCA) to assess the positive and negative symptoms as well as the cognitive symptoms based on the serum vitamin D levels. Result: All male schizophrenic patients had a low serum vitamin D level (mean16.67±5.6ng/ml) with 64.52% of them had vitamin D deficiency (<20 ng/ml). Interestingly, patients with vitamin D deficiency had a negative symptom (mean22.1±5.6ng/ml) whereas those with vitamin D insufficiency (20-29 ng/ml) had a positive symptom (mean 18.55±5.6ng/ml). Furthermore, patients with vitamin D deficiency had a lower impaired cognitive function value (mean 19.7±3.4ng/ml) compared to those with vitamin D insufficiency. Conclusions: A low vitamin D serum level in schizophrenic patients may play a role in the pathogenesis of this disorder. Further studies are needed to confirm this finding.

Objective: To know whether low levels of vitamin D affects severity of respiratory illness and its clinical outcomes. Design: Hospital based prospective cross sectional observational study. Setting : Pediatric Intensive Care Unit in Teaching Hospital affiliated with Medical College with study period of one and half years Methodology The study was performed on 50 cases of critically ill children with respiratory infectious disease admitted to the paediatric intensive care unit. Assessment of severity of respiratory infection was done with Paediatric respiratory severity score (PRESS). Serum vitamin D levels were assessed. Duration of PICU stay, hospital stay, need and type of respiratory support and its duration were also recorded. Results: Severe Vitamin D deficiency (<20ng/ml) was noted in 64% of total cases admitted with respiratory illness in PICU. Among these, 62.5% (20) cases had severe respiratory illness. The severity of respiratory illness was found to be highly significant with low Serum vitamin D values (p<0.01). Low serum vitamin D levels were also significantly associated with length of PICU stay (p<0.01), length of hospital stay (p=0.014), type of respiratory support (<0.001) and duration of respiratory support (p<0.001) Conclusion: A high prevalence of Vitamin D deficiency and insufficiency was found in critically ill children admitted with Respiratory infection. A strong statistical correlation was noted with Vitamin D deficiency and strongly associated with prolonged PICU care, respiratory support and hospitalization.

Introduction: Vitamin D is significantly associated with virus replication in chronic hepatitis B virus (HBV) infection. However, the relationship between low serum vitamin D levels and HBV “a” determinant mutations remains unknown. Methodology: A total of 133 chronically HBV-infected, treatment-naive patients were randomly selected in the present study. Serum vitamin D levels were measured by using liquid chromatography-mass spectrometry. The HBV “a” determinant was amplified, sequenced, and analyzed by nested polymerase chain reaction (PCR). Results: Among 133 patients, 36, 88, and 9 patients had vitamin D deficiency (25(OH)D < 14 ng/mL), vitamin D insufficiency (25(OH)D ≥ 14 and < 30 ng/mL), and normal vitamin D serum levels ((25(OH)D ≥ 30 ng/mL), respectively. As results showed, 36 [11 genotype B HBVs (HBV/B) and 25 genotype C HBVs (HBV/C)] were isolated from the vitamin D-deficient group, 88 (48 HBV/B and 40 HBV/C) from the vitamin D-insufficient group, and 4 HBV/C strains from the normal serum-vitamin D group. Compared to the HBV/B infected patients with vitamin D insufficiency, higher rates of amino acid mutation within “a” determinant were detected in HBV/B-infected, vitamin D-deficient patients. Moreover, the change frequency of M133 was 27.27% in HBV/B infected patients with vitamin D deficiency, which was significantly higher than those in the vitamin D-insufficient group (p = 0.040). Conclusions: Vitamin D deficiency is significantly associated with genotype B HBV “a” determinant mutations.

AbstractObjectiveBlack and Hispanic individuals synthesize less vitamin D per unit of sun exposure than white individuals. The relationship between UV radiation and vitamin D insufficiency in minorities has not been well explored.DesignProspective cohort study.SettingUsing the National Health and Nutrition Examination Survey, we obtained serum vitamin D levels for non-Hispanic Whites, Hispanics and non-Hispanic Blacks aged ≥18 years from 2000–2006. We linked these data with the average monthly solar UV index by census tract and data on sun exposure, vitamin D supplementation, health and demographics. We used multivariable regression analyses to assess vitamin D deficiency (<15 ng/ml) and insufficiency (<20 ng/ml) in January (when the UV index was lowest) by race/ethnicity and geography.SubjectsAdults (n 14 319) aged ≥18 years.ResultsA 1-point increase in the UV index was associated with a 0·51 ng/ml increase in vitamin D (95 % CI 0·35, 0·67 ng/ml; P<0·001). Non-Hispanic Black race and Hispanic ethnicity were associated with a 7·47 and 3·41 ng/ml decrease in vitamin D, respectively (both P<0·001). In January, an estimated 65·4 % of non-Hispanic Blacks were deficient in vitamin D, compared with 28·9 % of Hispanics and 14·0 % of non-Hispanic Whites. An estimated 84·2 % of non-Hispanic Blacks were insufficient in vitamin D v. 56·3 % of Hispanics and 34·8 % of non-Hispanic Whites. More non-Hispanic Blacks were estimated to be deficient in vitamin D in January in the highest UV index quartile than were non-Hispanic Whites in the lowest UV index quartile (60·2 % v. 25·7 %).ConclusionsWintertime vitamin D insufficiency is pervasive among minority populations, and not uncommon among non-Hispanic Whites.

Aim: To determine the relationship between maternal serum 25(OH) D concentrations and development of preeclampsia. Study Design: A cross sectional comparative study. Place and Duration of Study: Department of Obstetrics and Gynaecology, University of Abuja Teaching Hospital, Abuja, between March 2016 and February 2017. Methodology: We included 55 women with preeclampsia and 55 healthy women. Data obtained included sociodemographic characteristics, clothing style and duration of exposure to sun light.  ELISA method was used for evaluation of serum vitamin D levels. Results: The prevalence of VD deficiency in the population was 15%, while 16.8% and 73% of the participants had insufficient and normal levels respectively. The prevalence of VD deficiency in women with preeclampsia was 20.4% while that in healthy pregnant women was 9.4% (P=.19). The mean serum 25-OH-D level of women with pre-eclampsia was significantly lower than that of healthy women (34.5±14.9 vs. 43.5±15.1, P = .003). Preeclamptic women with vitamin D insufficiency delivered at a higher gestational age than those with vitamin D deficiency (37.67(2.77) weeks vs. 33.55(2.38) weeks respectively, P = .007). In the adjusted analysis of cases with vitamin D defficiency, the odds of developing preeclampsia was not statistically significant [odds ratio (OR) = 3.27, CI = 0.99-10.83, P =.05].  However, the odds of developing preeclampsia in women with Vitamin D insufficiency was statistically  significant (OR = 3.20, CI = 1.02–10.06,  = 0.046). Conclusion: In conclusion, an association between vitamin D deficiency and preeclampsia was not demonstrated in this study. The results however suggest that maternal vitamin D insufficiency in late pregnancy is an independent risk factor for preeclampsia.
