Abstract
Background & objectives Vitamin D plays an important role in bone metabolism, and liver is the intermediary site of vitamin D metabolism. The purpose of this study was to study the prevalence of vitamin D deficiency and bone health in patients with cirrhosis. Methods Prospectively, serum 25-hydroxy vitamin D [25(OH)D] level were assessed in cirrhotics by chemiluminescence method. Endocrine Society Clinical practice guideline was used to define deficiency and insufficiency of vitamin D. Bone mineral density (BMD) was assessed using dual-energy X-ray absorptiometry and the World Health Organization criteria was used to define osteoporosis and osteopenia. The lowest T score at the left hip neck or lumbar spine was taken as osteoporosis or osteopenia. The Child-Turcotte-Pugh score was used to assess the severity of cirrhosis. Results Cirrhotics (n=350, male: 278, compensated: 210) were included. Mean serum 25(OH)D level was 8.75 ng/ml. The prevalence of vitamin D deficiency (VDD) and low-BMD (osteopenia and osteoporosis) was 89.4 and 86 per cent, respectively. VDD, insufficiency and osteoporosis was found in 86.7, 11.9 and 33.8 per cent, respectively, in patients with compensated cirrhosis; and 93.6, 3.6 and 40 per cent, respectively, in patients with decompensated cirrhosis. Body mass index of >25 kg/m2 was protective for bone health. Interpretation & conclusions VDD and low-BMD is prevalent in Indian patients with cirrhosis and should be looked for in patients with cirrhosis for its prevention.

Administration of vitamin D and its metabolites in critically ill adult patients: an updated systematic review with meta-analysis of randomized controlled trials. Crit Care 2022; 26:268. [PMID: 36068584 PMCID: PMC9446655 DOI: 10.1186/s13054-022-04139-1] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Accepted: 08/25/2022] [Indexed: 11/22/2022] Open
Abstract
Background The clinical significance of vitamin D administration in critically ill patients remains inconclusive. The purpose of this systematic review with meta-analysis was to investigate the effect of vitamin D and its metabolites on major clinical outcomes in critically ill patients, including a subgroup analysis based on vitamin D status and route of vitamin D administration.
Methods Major databases were searched through February 9, 2022. Randomized controlled trials of adult critically ill patients with an intervention group receiving vitamin D or its metabolites were included. Random-effect meta-analyses were performed to estimate the pooled risk ratio (dichotomized outcomes) or mean difference (continuous outcomes). Risk of bias assessment included the Cochrane tool for assessing risk of bias in randomized trials. Results Sixteen randomized clinical trials with 2449 patients were included. Vitamin D administration was associated with lower overall mortality (16 studies: risk ratio 0.78, 95% confidence interval 0.62–0.97, p = 0.03; I2 = 30%), reduced intensive care unit length of stay (12 studies: mean difference − 3.13 days, 95% CI − 5.36 to − 0.89, n = 1250, p = 0.006; I2 = 70%), and shorter duration of mechanical ventilation (9 studies: mean difference − 5.07 days, 95% CI − 7.42 to − 2.73, n = 572, p < 0.0001; I2 = 54%). Parenteral administration was associated with a greater effect on overall mortality than enteral administration (test of subgroup differences, p = 0.04), whereas studies of parenteral subgroups had lower quality. There were no subgroup differences based on baseline vitamin D levels. Conclusions Vitamin D supplementation in critically ill patients may reduce mortality. Parenteral administration might be associated with a greater impact on mortality. Heterogeneity and assessed certainty among the studies limits the generalizability of the results.

Abstract
Abstract
Background
Abnormal vitamin D is prevalent in critical care settings, but its association with prognosis remains unclear. The study aimed to investigate the prevalence and predictors of abnormal blood 25-hydroxyvitamin D (25(OH)D), as well as its association with prognosis in critically ill patients.
Methods
Patients aged ≥ 18 years who were once admitted to the intensive care units (ICUs) of the Beth Israel Deaconess Medical Center between 2008 and 2019 with at least one measurement record of blood 25(OH)D were included as study population. Baseline characteristics associated with deficient or elevated blood 25(OH)D were investigated by univariable logistic regression analysis. The association between abnormal blood 25(OH)D and hospital mortality was examined by multivariable logistic regression analysis.
Results
A total of 1091 patients were included. Deficient 25(OH)D (< 30 ng/mL) was found in 790 (72.41%) patients and 17 (1.56%) were with an elevated level (> 60 ng/mL). A younger age, male, comorbid liver disease, and dialysis were risk factors of deficient blood 25(OH)D, while comorbid myocardial infarction, dementia, and rheumatic disease were protective factors evaluated by univariable logistic regression. Being admitted to cardiac vascular ICU or coronary care unit were associated with increased risk of elevated blood 25(OH)D. Patients with elevated blood 25(OH)D showed non-significantly higher hospital mortality compared to those with normal or deficient blood 25(OH)D (35.29% versus 14.44% and 14.56%, P = 0.058). After adjusted for potential confounding factors, elevated blood 25(OH)D was associated with increased risk of hospital mortality [odds ratio (OR) 3.80, 95% confidence interval (CI) 1.22–11.82, P = 0.021] when compared to those with normal blood 25(OH)D, but there was no significant association between deficient blood 25(OH)D and hospital mortality (OR 1.12, 95% CI 0.74–1.72, P = 0.589).
Conclusions
These findings suggest deficient blood 25(OH)D was rather common in critically ill patients, but was not an independent risk factor of hospital mortality, while elevated blood 25(OH)D was associated with worse prognosis.

Abstract
BACKGROUND & AIMS In critically ill patients with liver disease, vitamin D deficiency is associated with higher disease severity, increased frequency of infections, and worse outcomes. This study sought to describe the trend of vitamin D in orthotopic liver transplantation (OLT) recipients and its association with outcomes. METHODS Prospective observational study of 67 consecutive OLT recipients enrolled between September, 2016 and August, 2017 at IRCCS-ISMETT, Palermo (Italy). Trend of vitamin D levels and potential factors influencing it levels were evaluated through a generalized linear mixed regression model. RESULTS Sixty-four (95.5%) recipients were vitamin D deficient (<20 ng/ml), with a median value of 8.8 ng/ml [6.2-12.9], and forty-seven of these (70.1%) showed severe deficiency (<12 ng/ml) at baseline, 7.9 ng/ml [5.4-8.9]. The baseline vitamin D showed an inverse correlation with liver disease severity: Child-Pugh, MELD score, bilirubin, INR, and organ failure (p < 0.01) at baseline. Vitamin D increased on postoperative day (POD) 28 compared with POD1: +4.5 ng/ml, C.I. 95% 3.6-5.3 ng/ml, p < 0.01. Lower baseline vitamin D, donor age, transfusion of fresh frozen plasma (negative impact, all p < 0.05), and intra-operative bypass (positive impact at POD 28, p < 0.01) were associated with variation of vitamin D levels after transplantation. Incomplete graft recovery was associated with lower vitamin D on POD28: 8.2 ± 4.4 versus 13.8 ± 9.4 ng/ml, p < 0.01; the odds ratio (OR) was 0.84; CI 95% 0.73-0.97, p = 0.014. The OR for infections within POD 28 was inversely associated with baseline vitamin D: 0.87; CI 95% 0.79-0.98, p = 0.02, and with vitamin D level at baseline <12 ng/ml: OR 6.44; CI 95% 1.66-24.94; p < 0.01. CONCLUSIONS Preoperative Vitamin D is correlated with disease severity, and was highly associated with invasive infection in the first 28 PODs. After OLT, the value on POD 28 had a strong association with graft function.

Abstract
AIM Vitamin D plays an important role in the pathological process of chronic liver disease (CLD), and the degree of vitamin D deficiency is related to the severity of CLD. The aim of our study was to investigate the association between severe vitamin D deficiency and the risk of all-cause mortality in patients with liver cirrhosis (LC). METHODS The PubMed, Embase, and Cochrane Library databases were searched systematically for eligible studies from the earliest available date to 15 January 2019. The exposure and outcome of interest was serum vitamin D levels and all-cause mortality, respectively. The pooled risk ratio (RR) values and their 95% confidence intervals (CIs) were calculated through a meta-analysis. RESULTS Eight studies published from March 2013 to January 2019 were included, involving 1,339 patients with LC. The meta-analysis showed that a severe serum vitamin D deficiency was associated with an increased risk of mortality in patients with LC (RR = 1.79; 95% CI 1.44-2.22; P < 0.01). CONCLUSION Our meta-analysis confirmed the association between severe vitamin D deficiency and mortality risk, suggested serum vitamin D level as a new index to predict the prognosis, and emphasized the importance of vitamin D supplementation in LC patients.

Abstract
Critical illness in patients is characterized by systemic inflammation and oxidative stress. Vitamin D has a myriad of biological functions relevant to this population, including immunomodulation by the alteration of cytokine production and nuclear factor loop amplification. Low serum levels have consistently been found in observational studies conducted on critically ill patients, but the causality with mortality and worse outcomes has not been confirmed. The current focus is on interventional trials, whereas the pharmacokinetic profile of vitamin D administration remains sparse and the optimal strategy has not been confirmed. So far, high-dose oral or enteral supplementation is the most studied strategy. The largest randomized controlled trial published so far, the VITdAL-ICU (Effect of High-dose Vitamin D3 on Hospital Length of Stay in Critically Ill Patients with Vitamin D Deficiency) trial, showed no benefits on mortality in its primary analysis. However, secondary analysis suggested improvement in those patients with severe deficiency (i.e., 25-dihydroxyvitaminD <12 ng/mL). Smaller trials investigated intramuscular and intravenous administration and found interesting intermediate biochemical findings, including increased cathelicidins, but were not powered to investigate relevant clinical outcomes in the critically ill. The latest meta-analysis, which was recently published, does not support benefits of vitamin D supplementation in the heterogeneous population of critically ill patients. The European guidelines, published in the last year, suggest supplementing severely deficient patients with levels <12.5 ng/mL within the first week after ICU admission. However, other societies do not support such supplementation in their older recommendations. Large trials are currently recruiting ICU patients and could elucidate potential clinical benefits of vitamin D therapy in the critically ill.
