[PMID: 39100634 PMCID: PMC11294743 DOI: 10.1016/j.aace.2024.04.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 04/22/2024] [Accepted: 04/25/2024] [Indexed: 08/06/2024] Open
Abstract
Background/Objective Severe hypocalcemia is common in critically ill patients. There are different mechanisms. To our knowledge, there are no data about the acute presentation of hypocalcemia at the time of diagnosis of aplastic anemia (AA). The objective of this case report was to describe the case of hypoparathyroidism with severe hypocalcemia in a critically ill patient with AA. Case Report A 60-year-old man presented with severe hypocalcemia with a calcium level of 6.1 mg/dL (reference range, 8.6-10.3 mg/dL) and hypoparathyroidism with a parathyroid hormone level of 11 pg/mL (reference range, 12-88 pg/mL). He developed a critical state caused by newly diagnosed AA and its complications, such as an acute decrease in the platelet value to a critically low level of 2 × 103/cmm, complicated by neutropenic fever and lower gastrointestinal bleeding. After the initiation of immunosuppressive therapy for AA, his parathyroid hormone-calcium metabolism improved and remained stable but did not normalize completely. Discussion In our patient, hypoparathyroidism with hypocalcemia may have been caused by cytokine-related upregulation of the calcium-sensing receptor in the setting of AA. On the other hand, given the severity of the initial hypocalcemia and only partial improvement in calcium homeostasis with residual mild hypocalcemia after treatment initiation for AA, autoimmune causes cannot be entirely ruled out, nor could a combination of cytokine-mediated and autoimmune causes. Conclusion It is essential to treat the underlying causes of hypocalcemia, which, in this case, were AA and hypoparathyroidism.

Abstract
BACKGROUND Vitamin D deficiency (VDD) is highly prevalent in the pediatric intensive care unit (ICU) and associated with worse clinical course. Trials in adult ICU demonstrate rapid restoration of vitamin D status using an enteral loading dose is safe and may improve outcomes. There have been no published trials of rapid normalization of VDD in the pediatric ICU. METHODS We conducted a multicenter placebo-controlled phase II pilot feasibility randomized clinical trial from 2016 to 2017. We randomized 67 critically ill children with VDD from ICUs in Canada, Chile and Austria using a 2:1 randomization ratio to receive a loading dose of enteral cholecalciferol (10,000 IU/kg, maximum of 400,000 IU) or placebo. Participants, care givers, and outcomes assessors were blinded. The primary objective was to determine whether the loading dose normalized vitamin D status (25(OH)D > 75 nmol/L). Secondary objectives were to evaluate for adverse events and assess the feasibility of a phase III trial. RESULTS Of 67 randomized participants, one was withdrawn and seven received more than one dose of cholecalciferol before the protocol was amended to a single loading dose, leaving 59 participants in the primary analyses (40 treatment, 19 placebo). Thirty-one/38 (81.6%) participants in the treatment arm achieved a plasma 25(OH)D concentration > 75 nmol/L versus 1/18 (5.6%) the placebo arm. The mean 25(OH)D concentration in the treatment arm was 125.9 nmol/L (SD 63.4). There was no evidence of vitamin D toxicity and no major drug or safety protocol violations. The accrual rate was 3.4 patients/month, supporting feasibility of a larger trial. A day 7 blood sample was collected for 84% of patients. A survey administered to 40 participating families showed that health-related quality of life (HRQL) was the most important outcome for families for the main trial (30, 75%). CONCLUSIONS A single 10,000 IU/kg dose can rapidly and safely normalize plasma 25(OH)D concentrations in critically ill children with VDD, but with significant variability in 25(OH)D concentrations. We established that a phase III multicentre trial is feasible. Using an outcome collected after hospital discharge (HRQL) will require strategies to minimize loss-to-follow-up.

Vitamin D Deficiency: An Underestimated Factor in Sepsis? Int J Mol Sci 2023; 24:ijms24032924. [PMID: 36769240 PMCID: PMC9917708 DOI: 10.3390/ijms24032924] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 01/28/2023] [Accepted: 01/31/2023] [Indexed: 02/05/2023] Open
Abstract
Vitamin D is an important immune modulator that is linked to infection susceptibility. It has been suggested that vitamin D deficiency plays a role in sepsis and septic shock because vitamin-D-related pathways are associated with various immunological, endocrine, and endothelial functions. Previous research has yielded inconclusive results regarding the link between mortality and vitamin D deficiency in sepsis patients. In patients with sepsis and severe vitamin D deficiency, an adequate vitamin D concentration may reduce mortality. Randomized controlled trials to assess the influence of vitamin D supplementation on clinical outcomes in sepsis patients with vitamin D deficiency are uncommon. We will provide an overview of the current knowledge about the relationship between vitamin D and sepsis in this review, as well as consider the potential value of vitamin D supplementation in this situation.

Abstract
Vitamins are essential micronutrients with key roles in many biological pathways relevant to sepsis. Some of these relevant biological mechanisms include antioxidant and anti-inflammatory effects, protein and hormone synthesis, energy generation, and regulation of gene transcription. Moreover, relative vitamin deficiencies in plasma are common during sepsis and vitamin therapy has been associated with improved outcomes in some adult and pediatric studies. High-dose intravenous vitamin C has been the vitamin therapy most extensively studied in adult patients with sepsis and septic shock. This includes three randomized control trials (RCTs) as monotherapy with a total of 219 patients showing significant reduction in organ dysfunction and lower mortality when compared to placebo, and five RCTs as a combination therapy with thiamine and hydrocortisone with a total of 1134 patients showing no difference in clinical outcomes. Likewise, the evidence for the role of other vitamins in sepsis remains mixed. In this narrative review, we present the preclinical, clinical, and safety evidence of the most studied vitamins in sepsis, including vitamin C, thiamine (i.e., vitamin B1), and vitamin D. We also present the relevant evidence of the other vitamins that have been studied in sepsis and critical illness in both children and adults, including vitamins A, B2, B6, B12, and E. IMPACT: Vitamins are key effectors in many biological processes relevant to sepsis. We present the preclinical, clinical, and safety evidence of the most studied vitamins in pediatric sepsis. Designing response-adaptive platform trials may help fill in knowledge gaps regarding vitamin use for critical illness and association with clinical outcomes.

Abstract
Background: Critically ill Indian children have a higher prevalence of vitamin D deficiency. However, there is not much data available on the subgroup with sepsis. It has been reported that there is an impaired response of parathyroid hormone (PTH) to vitamin D deficiency in critically ill children and adults. Hence, we also sought to analyze the PTH response to vitamin D among the subgroup of critically ill children with sepsis. Patients and methods: Vitamin D and PTH levels of 84 critically ill children with sepsis (cases) and 84 controls were compared between November 2018 and February 2020. Hypovitaminosis D was defined as levels <30 ng/mL. Results: The median (IQR) of vitamin D for cases was 26 (21.30–29.95) ng/mL and that for controls 39.3 (33.65–50.2) ng/mL; p <0.001. Cases had a higher prevalence of hypovitaminosis D as compared to controls (79.7 vs 9.5%; p <0.001). Among the cases, mortality was 24.6% in the 65 children with hypovitaminosis D and 10.5% in those with sufficient vitamin D; the differences were not statistically significant (p = 0.339). There were no significant differences in the duration of pediatric intensive care unit (PICU) stay, serum calcium, PTH, and disease severity among the aforementioned groups. Out of the 65 children with hypovitaminosis D, only 9 (13.8%) were PTH responders. There were no statistically significant differences in mortality, the PICU stay, or disease severity at admission between PTH responders and nonresponders. Conclusions: Hypovitaminosis D was more prevalent among critically ill children with sepsis compared to controls. Parathyroid gland response to hypovitaminosis D was impaired in children with sepsis.

Abstract
INTRODUCTION Vitamin D deficiency in children is related to the augmented risk of bone illnesses, but its effect on critically ill children is still conflicting. This meta-analysis study was performed to assess the relationship between vitamin D deficiency in children and sepsis, paediatric risk of mortality III score, need for ventilation support, length of hospital stay, and duration of mechanical ventilation in critically ill children. METHODS Through a systematic literature search up to June 2020, 16 studies with 2382 children, 1229 children of them with vitamin D deficiency, were found recording relationships between vitamin D deficiency and sepsis, paediatric risk of mortality III score, need for ventilation support, length of hospital stay, and/or duration of mechanical ventilation. Odds ratio (OR) with 95% confidence intervals (CIs) was calculated between vitamin D deficiency children to non-vitamin D deficiency children on the different outcomes in critically ill children using the dichotomous or continuous methods with a random or fixed-effect model. RESULTS The vitamin D deficiency children category had significantly higher sepsis (OR, 2.35; 95% CI, 1.19-4.63, P = .01); paediatric risk of mortality III score (OR, 2.19; 95% CI, 1.13-4.25, P = .02); higher length of hospital stay (OR, 4.26; 95% CI, 0.81-7.70, P = .02); higher duration of mechanical ventilation (OR, 1.89; 95% CI, 0.22-3.56, P = .03) compared with that in the non-vitamin D deficiency children. However, the need for ventilation support in vitamin D deficiency children did not significantly differ from non-vitamin D deficiency children (OR, 2.00; 95% CI, 0.98-4.07, P = .06) with relatively higher results in vitamin D deficiency children. CONCLUSIONS Vitamin D deficiency in children might have an independent relationship with higher sepsis, paediatric risk of mortality III score, length of hospital stay, and duration of mechanical ventilation. The relation was relative with a higher risk in need for ventilation support with vitamin D deficiency children. This relationship encouraged us to recommend testing vitamin D levels in all critically ill children and providing them with supplemental vitamin D as prophylaxis.

Abstract
BACKGROUND Sepsis leads to the high mortality in critically ill infants and children. It is still controversial whether vitamin D deficiency was associated with the incidence of sepsis. Thus we designed the systematic review and meta-analysis. METHODS The Ovid Medline, Embase, PubMed, and Cochrane library were systematically searched until April 5, 2020. The 25 hydroxyvitamin D (25-OHD) level was recorded and set 20 ng/mL as cut-off in cohort study to divide the lower and higher 25-OHD group. The odds ratio (OR) and 95% confidence intervals (CIs) were calculated for comparing the impact of vitamin D deficiency on the incidence of sepsis in critically ill children. RESULTS A total of 27 studies were included with 17 case-control studies and 10 cohort studies. In those case-control studies, the maternal 25-OHD level and neonatal 25-OHD level in sepsis group was significant lower than non-sepsis group (P < .001). The percentage of severe vitamin D deficiency was significant higher in sepsis group comparing to non-sepsis group (odds ratio [OR] = 2.66, 95% CI = 1.13-6.25, P < .001). In those cohort studies, the incidence of sepsis in lower 25-OHD group was 30.4% comparing with 18.2% in higher 25-OHD level group. However, no statistical significant difference in terms of mechanical ventilation rate and 30-day mortality. CONCLUSION We demonstrated that critically ill infants and children with sepsis could have a lower 25-OHD level and severe vitamin D deficiency comparing to those without sepsis. Future studies should focus on the association of vitamin D supplement and the occurrence of sepsis in critically ill children.

Abstract
Background: We conducted a meta-analysis to investigate the possible effects of vitamin D deficiency on clinical outcomes of critically-ill children.Methods: We searched Scopus-Embase and PubMed-Medline databases to find eligible observational articles. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to estimate the strength of associations.Results: Seventeen articles (eighteen studies) involving 2987 critically ill patients met our inclusion criteria. Vitamin D deficiency was not associated with increased mortality. A significant association was only observed in very high developed countries between vitamin D deficiency and risk of sepsis [OR (95%CIs): 2.65 (1.30, 5.41)] and ventilation support requirement [OR (95%CIs): 1.35 (1.03, 1.77)].Conclusion: Our findings suggest that vitamin D deficiency is not associated with higher mortality among critically ill children but increases susceptibility to sepsis and the need for ventilator support in critical care settings.

Abstract
A meta-analysis study was performed to evaluate the relationship between vitamin D deficiency children and sepsis and acute and critically mortality. Through a systematic literature search up to December 2019, 23 studies with 4451 children, 2500 children with vitamin D deficiency were identified reporting relationships between vitamin D deficiency and sepsis and/or acute and critical care unit mortality (six sepsis only, four acute and critically mortality only and 13 both sepsis and acute and critically mortality). Odd ratio (OR) with 95% confidence intervals (CIs) was calculated comparing vitamin D deficiency children to normal vitamin D children on the bases of sepsis and mortality in acute and critical care units using the dichotomous method with a random effect model. No significant difference was found between males and females in pooled studies all together (OR, 0.72; 95% CI, 0.43-1.22). Vitamin D deficiency children (OR, 2.24; 95% CI, 1.42-3.53) had higher sepsis compared to normal vitamin D children. Also, vitamin D deficiency children (OR, 1.77; 95% CI, 1.26-2.49) had higher acute and critically mortality compared to normal vitamin D children but not as much as that in sepsis. The extent of increased sepsis was higher than that in acute and critically mortality. The impact of vitamin D deficiency in children was observed in all populations. Based on this meta-analysis, vitamin D deficiency in children may have an independent-relationship with up to 2.24 fold risk of sepsis and acute and critical care unit mortality. This relationship forces us to recommend checking vitamin D concentration in all critically ill children.

Abstract
BACKGROUND The consequences of vitamin D deficiency regarding sepsis in children remain controversial. We conducted a meta-analysis of studies evaluating the association between vitamin D status and sepsis in children. METHODS We used EMBASE, Ovid Medline and Cochrane Library to conduct a meta-analysis of studies published in English before November 21, 2017. RESULTS Among 1146 initially identified studies, we included 13 studies according to predefined inclusion criteria comprising 975 patients and 770 control participants. According to a random effects model, the mean difference in 25(OH)D levels (nmol/L) between participants with sepsis (444) and controls (528) was (mean difference, -18.55; 95% confidence interval (CI), -19.45 to -17.66, p < 0.05). The association between vitamin D deficiency and sepsis was significant, with an odds ratio (OR) = 1.13 (95% CI, 1.18 to 1.50, p < 0.05). Factors that could explain differences in the results include the study location/medical conditions, study design, 25(OH)D assay methods, diagnostic sepsis at different ages, diagnostic criteria for sepsis, and sepsis with comorbidities. CONCLUSIONS The association between vitamin D deficiency/lower 25(OH)D levels and sepsis was significant in children and neonates. Further studies are required to confirm the results by considering more confounders.

Abstract
OBJECTIVES To estimate the prevalence of 25-hydroxyvitamin D (25(OH)D) deficiency and investigate its association with mortality in children with acute or critical conditions. DESIGN Systematic review and meta-analysis of observational studies. DATA SOURCES PubMed, OVID, Google Scholar and the Cochrane Library searched until 21 December 2018. ELIGIBILITY CRITERIA Studies of children hospitalised with acute or critical conditions who had blood 25(OH)D levels measured. DATA EXTRACTION AND SYNTHESIS We obtained pooled prevalence estimates of 25(OH)D deficiency and ORs for mortality. We calculated 95% CI and prediction intervals and investigated heterogeneity and evidence of small-study effects. RESULTS Fifty-two studies were included. Of 7434 children, 3473 (47.0%) were 25(OH)D deficient (<50 nmol/L). The pooled prevalence estimate of 25(OH)D deficiency was 54.6% (95% CI 48.5% to 60.6%, I2=95.3%, p<0.0001). Prevalence was similar after excluding smaller studies (51.5%). In children with sepsis (18 studies, 889 total individuals) prevalence was 64.0% (95% CI 52.0% to 74.4%, I2=89.3%, p<0.0001) and 48.7% (95% CI 38.2% to 59.3%; I2=94.3%, p<0.0001) in those with respiratory tract infections (RTI) (25 studies, 2699 total individuals). Overall, meta-analysis of mortality (18 cohort studies, 2463 total individuals) showed increased risk of death in 25(OH)D deficient children (OR 1.81, 95% CI 1.24 to 2.64, p=0.002, I2=25.7%, p=0.153). Four (22.0%) of the 18 studies statistically adjusted for confounders. There were insufficient studies to meta-analyse sepsis and RTI-related mortality. CONCLUSIONS Our results suggest that 25(OH)D deficiency in acute and critically ill children is high and associated with increased mortality. Small-study effects, reverse causation and other biases may have confounded results. Larger, carefully designed studies in homogeneous populations with confounder adjustment are needed to clarify the association between 25(OH)D levels with mortality and other outcomes.

Abstract
Objectives To investigate platelet volume indices and in-hospital mortality in children on mechanical ventilation. Methods This retrospective study included children aged <16 years on mechanical ventilation, and compared parameters, measured on admission, between survivors and non-survivors. Dynamic platelet volume indices over the first 7 days were visualized. Independent risk factors of mortality were identified using multivariate logistic regression analysis. Results Out of 2 319 children aged 28 days–3 years, serum albumin (odds ratio [OR] 0.9, 95% confidence interval [CI] 0.85, 0.96), bilirubin (OR 1.01, 95% CI 1.0, 1.77), and lactic acid (OR 1.22, 95% CI 1.05, 1.38) levels were associated with mortality. Out of 2 415 children aged > 3 years, procalcitonin (OR 1.01, 95% CI 1.0, 1.01) and lactic acid (OR 1.22, 95% CI 1.09, 1.35) were associated with mortality. Platelet volume indices on admission were not independently associated with mortality in either group. Mean platelet volume (MPV) and platelet distribution width (PDW) showed different trends in non-survivors versus survivors over 1 week in both age groups. Conclusions Platelet volume indices may be associated with mortality in critically ill children receiving mechanical ventilation.

Abstract
BACKGROUND Vitamin D deficiency (VDD) has been hypothesized not only to be common but also to represent a potentially modifiable risk factor for greater illness severity and clinical outcome during critical illness. The objective of this systematic review was to determine the frequency of VDD in pediatric critical illness and its association with clinical outcomes. METHODS MEDLINE, Embase, and CENTRAL were searched through December 12, 2016, with no date or language restrictions. The primary objective was to estimate the prevalence of VDD in the pediatric intensive care unit (PICU) and compare vitamin D status with healthy control populations. Secondary objectives were to evaluate whether VDD is associated with mortality, increased illness severity, PICU interventions, and patient clinical course. Random effects meta-analysis was used to calculate pooled VDD event rate, compare levels with those of control subjects, and evaluate for associations between VDD and clinical outcome. RESULTS Among 2700 citations, 17 studies meeting study eligibility were identified. The studies reported a total of 2783 critically ill children and had a median sample size of 120 (range 12-511). The majority of studies used a 25-hydroxyvitamin D [25(OH)D] level less than 50 nmol/L to define VDD, and the pooled VDD prevalence was 54.8 (95% CI 45.4-63.9). Average 25(OH)D levels were significantly lower in PICU patients than in healthy control subjects (pooled difference -17.3 nmol/L, 95% CI -14.0 to -20.6). In a meta-analysis calculation, we found that VDD was associated with increased mortality (OR 1.62, 95% CI 1.11-2.36), illness severity, and need for PICU interventions. CONCLUSIONS Approximately 50% of critically ill children have VDD at the time of PICU admission, defined as a blood total 25(OH)D concentration under 50 nmol/L. VDD was further determined to be associated with greater illness severity, multiple organ dysfunction, and mortality in the PICU setting. Clinical trials are required to determine if optimization of vitamin D status improves patient outcome. TRIAL REGISTRATION PROSPERO, CRD42016026617 . Registered on 11 January 2016.
