25 Hydroxyvitamin D

Introduction: Patients in intensive care units (ICUs) are at high risk of unfavorable outcomes. Considering the role of vitamin D (Vit D) in cardiovascular and immune functions, Vit D deficiency could affect ICU patients’ outcomes. This study aimed to evaluate Vit D status and its predictive value for outcome in ICU patients. Patients and Methods: A total of 169 ICU patients were followed during ICU stay. Primary outcome was the occurrence of at least one major adverse event; secondary outcomes were organ failure, septic shock, ICU-acquired infection, other adverse events, and ICU mortality. Plasma 25-hydroxyvitamin D (25(OH)D) was assessed by immunoassay. Multivariate Cox regression analyses were performed to test the associations of low 25(OH)D levels with poor outcomes. Results: Around 75% of patients had 25(OH)D levels <12 ng/ml. During their ICU stay, 114 patients experienced a major adverse event, 85 patients presented an ICU-acquired infection, and 22 patients died. Plasma 25(OH)D levels <12 ng/ml were associated with higher risk of major adverse events, Hazard ratio [95% CI], 4.47 [1.77, 11.3], p = .020, and ICU-acquired infection, 2.67 [1.01, 7.42], p = .049, but not with increased risk of ICU mortality. Conclusions: Hypovitaminosis D is very common in ICU patients. Results of the present study show that low plasma 25(OH)D levels are associated with increased risk of unfavorable outcomes in these patients. Additional research is needed to investigate the impact of Vit D status and effect of Vit D supplementation in ICU patients.

We aimed to examine whether low intensive care unit (ICU) admission 25-hydroxyvitamin D (25(OH)D) levels are associated with worse outcomes of COVID-19 pneumonia. This was a prospective observational study of SARS-CoV2 positive critically ill patients treated in a multidisciplinary ICU. Thirty (30) Greek patients were included, in whom 25(OH)D was measured on ICU admission. Eighty (80%) percent of patients had vitamin D deficiency, and the remaining insufficiency. Based on 25(OH)D levels, patients were stratified in two groups: higher and lower than the median value of the cohort (15.2 ng/mL). The two groups did not differ in their demographic or clinical characteristics. All patients who died within 28 days belonged to the low vitamin D group. Survival analysis showed that the low vitamin D group had a higher 28-day survival absence probability (log-rank test, p = 0.01). Critically ill COVID-19 patients who died in the ICU within 28 days appeared to have lower ICU admission 25(OH)D levels compared to survivors. When the cohort was divided at the median 25(OH)D value, the low vitamin D group had an increased risk of 28-day mortality. It seems plausible, therefore, that low 25(OH)D levels may predispose COVID-19 patients to an increased 28-day mortality risk.

Background: Critically ill patients frequently require intrahospital transfer for diagnostic or therapeutic procedures, or transfer to the intensive care unit. Intrahospital transfer exposes patients to an increased risk of adverse events. The reported rate of adverse events ranges from 4.2% to 79% based on data from high income countries. There is limited data available on intrahospital transfers in the South African context. This study aimed to determine the incidence of adverse events during intrahospital transfer, the physiological effects of intrahospital transfer, identify potential risk factors for adverse events and determine if adverse events were associated with poor clinical outcomes. Methods: The study was a single-centre, prospective, observational study of adult patients undergoing transport between the operating theatre and the intensive care unit (or vice versa) of a tertiary academic hospital in South Africa. Demographic data, transfer data (including adverse events, and the physiological parameters of the patients before and after transfer), and intensive care unit outcome data was collected between September 2018 and May 2019. Results: Data on 94 transfers was collected. Adverse events occurred in 23.4% (95% CI 14.7–32.1%) of transfers. Clinical adverse events, namely hypotension requiring management, made up 55% of the adverse events, while the remaining were technical adverse events (32% monitor failure, 9% ventilator failure and 4% infusion pump failure). The median transfer time was 10 minutes. Patients who developed adverse events during transfer were significantly older (median age 48 years versus 37 years, p = 0.037) and were significantly more likely to be receiving inotropic support (81.8% versus 51.4%, OR 4.26; 95% CI 1.31–13.82, p = 0.011) than those who did not have adverse events. Only the association with inotropic support remained on multivariable analysis. Patients who suffered an adverse event during transfer had a significantly higher mortality than those who did not have an adverse event (63.6% versus 30.6%, OR 3.98; 95% CI 1.46–10.84, p = 0.005) on univariate analysis, however this association was no longer significant on multivariable analysis. Increasing age, inotropic support and transfer by a medical officer as opposed to a registrar remained significant predictors on multivariable analysis. Significant physiological changes were noted in 80.9% of patients, with 64.9% of patients showing deterioration in at least one physiological parameter. Conclusion: Adverse events are common during the transfer of critically ill patients between the operating theatre and the intensive care unit. Even in the absence of adverse events, physiological changes occur in the majority of patients undergoing transfer. Patients receiving inotropic support are at increased risk of adverse events during transfer and enhanced attention to pre-transfer preparation and intratransfer management is warranted in these patients. The potential associations between adverse events during transfer and transferring personnel and ICU mortality needs to be explored in further studies.

Abstract Background Carbapenem-resistant Klebsiella pneumoniae (CRKP) has become a threat to public health, most notably as a superbug causing nosocomial infections. Patients in the intensive care unit (ICU) are at increased risk of hospital-acquired K pneumoniae infection, especially CRKP. This study was conducted to investigate the frequency of gastrointestinal and nasopharyngeal K pneumoniae colonization and its contribution to infections in ICU patients. Methods A 3-month prospective cohort study was performed in which 243 ICU patients were screened for intestinal and nasopharyngeal carriage of K pneumoniae at admission and once per week thereafter. The colonization and clinical infection isolates were analyzed by antimicrobial susceptibility testing to identify CRKP and were characterized by multilocus sequence typing (MLST) and whole-genome sequencing combined with epidemiological data to investigate the resistance mechanisms and assess the possible transmitted infection. Results Twenty-eight percent (68 of 243) of patients tested positive for carriage of K pneumoniae immediately upon admission to ICU, 54% (37 of 68) of which were nonduplicate CRKP isolates. Patients with carbapenem-susceptible K pneumoniae (CSKP) colonization at admission were more likely to acquire CRKP colonization during the ICU stay compared with patients without K pneumoniae colonization at admission. The incidence of subsequent CRKP infection in the baseline CSKP (32.3%, 10 of 31) and CRKP (45.9%, 17 of 37) carrier group was significantly higher than that of the baseline non-KP carrier group (8.6%, 15 of 175). The risk factors associated with acquired CRKP colonization during the ICU stay among negative CRKP colonization at admission included previous exposure to carbapenem, tigecycline or β-lactam/β-lactamases inhibitor, and invasive processes or surgical operations. Sixty-four percent (27 of 42) of patients with K pneumoniae infection were colonized by clonally related K pneumoniae strains according to enterobacterial repetitive intergenic consensus sequence-polymerase chain reaction analysis. ST11 (72%, 53 of 74) was the most predominant MLST type of clonally related CRKP isolate colonizing these patients, followed by ST15 (26%, 19 of 74). Conclusions The colonization of K pneumoniae may increase the incidence of corresponding K pneumoniae infection in critically ill patients in the ICU. High prevalence of ST11 CRKP (due to blaKPC-2) carriage and infection in ICU was observed.

Abstract Context: Blood levels of 25-hydroxyvitamin D [25(OH)D] is the generally accepted indicator of vitamin D status, but no universal reference level has been reached. Objective: The objective of the study was to determine the threshold at which low plasma 25(OH)D levels are associated with fractures in elderly men and clarify the importance of low levels on total fracture burden. Design and Participants: In the Uppsala Longitudinal Study of Adult Men, a population-based cohort (mean age, 71 yr, n = 1194), we examined the relationship between 25(OH)D and risk for fracture. Plasma 25(OH)D levels were measured with high-pressure liquid chromatography-mass spectrometry. Setting: The study was conducted in the municipality of Uppsala in Sweden, a country with a high fracture incidence. Main Outcome Measure: Time to fracture was measured. Results: During follow-up (median 11 yr), 309 of the participants (26%) sustained a fracture. 25(OH)D levels below 40 nmol/liter, which corresponded to the fifth percentile of 25(OH)D, were associated with a modestly increased risk for fracture, multivariable-adjusted hazard ratio 1.65 (95% confidence interval 1.09–2.49). No risk difference was detected above this level. Approximately 3% of the fractures were attributable to low 25(OH)D levels in this population. Conclusions: Vitamin D insufficiency is not a major cause of fractures in community-dwelling elderly men in Sweden. Despite the fact that cutaneous synthesis of previtamin D during the winter season is undetectable at this northern latitude of 60°, only one in 20 had 25(OH)D levels below 40 nmol/liter, the threshold at which the risk for fracture started to increase. Genetic adaptations to limited UV light may be an explanation for our findings.

25 Hydroxyvitamin D

Insufficient blood levels of the neurohormone vitamin D are associated with increased risk of COVID-19 severity and mortality. Despite the global rollout of vaccinations and promising preliminary results, the focus remains on additional preventive measures to manage COVID-19. Results conflict on vitamin D’s plausible role in preventing and treating COVID-19. We examined the relation between vitamin D status and COVID-19 severity and mortality among the multiethnic population of the United Arab Emirates. Our observational study used data for 522 participants who tested positive for SARS-CoV-2 at one of the main hospitals in Abu Dhabi and Dubai. Only 464 of those patients were included for data analysis. Demographic and clinical data were retrospectively analyzed. Serum samples immediately drawn at the first hospital visit were used to measure serum 25-hydroxyvitamin D [25(OH)D] concentrations through automated electrochemiluminescence. Levels < 12 ng/mL were significantly associated with higher risk of severe COVID-19 infection and of death. Age was the only other independent risk factor, whereas comorbidities and smoking did not contribute to the outcomes upon adjustment. Sex of patients was not an important predictor for severity or death. Our study is the first conducted in the UAE to measure 25(OH)D levels in SARS-CoV-2-positive patients and confirm the association of levels < 12 ng/mL with COVID-19 severity and mortality.

Objectives: The application of Central Venous Catheters (CVC) is associated with increased risk of microbial colonization and infection. The aim of present study was to assess the frequency of pathogens colonizing CVC and to determine their susceptibility pattern to various antimicrobial agents. Materials and methods: A total of 253 samples of CVC from intensive care units (ICU) patients were received for culture during 2003. All microorganisms were identified by standard microbiological methods and the susceptibility to antimicrobial agents was determined according to NCCLS recommendations. Results: A total of 184 (72.7%) cultures were positive and 223 pathogens were isolated. Coagulase negative staphylococci (CNS) were the dominant isolates (24.7%), followed by Enterobacter spp. (12.1%), Pseudomonas spp. (11.7%), Enterococcus spp. (9.9%), Klebsiella spp. (8.6%), Candida spp. (7.6%), Acinetobacter spp. (7.6%), other Gram negative nonfermentative bacilli (5.8%), Serratia spp. (4.5%), Staphylococcus aureus (2.6%), Proteus mirabilis (2.2%), E. coli (1.8%) and Citrobacter spp. (0.9%). Meropenem (84.5%) and vancomycin (100%) remain the most effective antimicrobial agents against Gram negative and Gram positive bacteria, respectively. Conclusion: Gram negative bacilli and CNS are the commonest microorganisms colonizing CVC from ICU patients. The increasing resistance of the bacteria to antimicrobial agents is the major problem in spite of restricted policy of using antimicrobial agents in ICU.

Abstract Background: Gastroscopy is a useful procedure for gastrointestinal (GI) bleeding. No definite clinical guidelines recommend on the choice of gastroscopy implementation in the intensive care unit (ICU) patient with suspected GI bleeding. The objective of this retrospective study was to compare the clinical effectiveness of gastroscopy in critically ill patients using high-dose proton pump inhibitor for suspected bleeding.Methods: ICU patients using a high-does proton pump inhibitor for suspected GI bleeding from January 2015 to February 2020 were retrospectively included. Massive GI bleeding, such as hematemesis and hematochezia, were excluded. After propensity score matching (PSM) between the gastroscopy and no gastroscopy groups, the change in hemoglobin level, requirement of RBC transfusion, length of ICU stay, and ICU mortality were compared. Results: Of the 116 subjects included, 34 patients had gastroscopy during ICU stay. Among the gastroscopy group, 13 (38.2%) patients showed normal findings, and the most frequent abnormal finding was gastric ulcer (n = 9, 26.5%), and 12 patients (35.3%) had a hemostatic procedure. After PSM, the gastroscopy group needed more red blood cell transfusion than the no-gastroscopy group (P = 0.01). There was no significant difference in the change in hemoglobin level (P = 0.10), length of ICU stay (P = 0.64), and ICU mortality (P = 0.55).Conclusion: This retrospective study showed that gastroscopy had no definite clinical benefit in ICU patients using high-dose proton pump inhibitor for suspected GI bleeding.

AbstractLow serum concentrations of several vitamins have been linked to increased risk of diseases including insulin resistance and type 2 diabetes (T2D). Fish is a good source of several vitamins, and the prevalence of T2D is low in populations with high fish intake. The aim of the present study was to investigate the effects of high fish intake on vitamins in serum from adults in autumn in South-Western Norway at 60° north latitude. In this randomised clinical trial, sixty-three healthy participants with overweight/obesity consumed 750 g/week of either cod (n 22) or salmon (n 22) as five weekly dinners or were instructed to continue their normal eating habits but avoid fish intake (Control group, n 19) for 8 weeks. The estimated vitamin D intake was significantly increased in the Salmon group when compared with the Cod group (P = 6·3 × 10−4) and with the Control group (P = 3·5 × 10−6), with no differences between groups for estimated intake of vitamins A, B1, B2, B3, B6, B9, C and E. Serum 25-hydroxyvitamin D3 concentration was decreased in all groups after 8 weeks; however, the reduction in the Salmon group was significantly smaller compared with the Cod group (P = 0·013) and the Control group (P = 0·0060). Cod and salmon intake did not affect serum concentrations of the other measured vitamins. The findings suggest that 750 g/week of salmon was not sufficient to prevent a decrease in serum 25-hydroxyvitamin D3 in autumn in South-Western Norway in adults with overweight/obesity.

Abstract Objective: To determine the impact of methicillin-resis-tant Staphylococcus aureus (MRSA) colonization on the occurrence of S aureus infections (methicillin-resistant and methicillin-suscep-tible), the use of glycopeptides, and outcome among intensive care unit (ICU) patients. Design: Prospective observational cohort survey. Setting: A medical-surgical ICU with 10 single-bed rooms in a 460-bed, tertiary-care, university-affiliated hospital. Patients: A total of 1,044 ICU patients were followed for the detection of MRSA colonization from July 1, 1995, to July, 1 1998. Methods: MRSA colonization was detected using nasal samples in all patients plus wound samples in surgical patients within 48 hours of admission or within the first 48 hours of ICU stay and weekly thereafter. MRSA infections were defined using Centers for Disease Control and Prevention standard definitions, except for ventilator-associated pneumonia and catheter-related infections, which were defined by quantitative distal culture samples. Results: One thousand forty-four patients (70% medical patients) were included in the analysis. Mean age was 61±18 years; mean Simplified Acute Physiologic Score (SAPS) II was 36.4±20; and median ICU stay was 4 (range, 1-193) days. Two hundred thirty-one patients (22%) died in the ICU. Fifty-four patients (5.1%) were colonized with MRSA on admission, and 52 (4.9%) of 1,044 acquired MRSA colonization in the ICU. Thirty-five patients developed a total of 42 S aureus infections (32 MRSA, 10 methi-cillin-susceptible). After factors associated with the development of an S aureus infection were adjusted for in a multivariate Cox model (SAPS II &gt;36: hazard ratio [HR], 1.64; P=.09; male gender: HR, 2.2; P=.05), MRSA colonization increased the risk of S aureus infection (HR, 3.84; P=.0003). MRSA colonization did not influence ICU mortality (HR, 1.01; P=.94). Glycopeptides were used in 11.4% of the patients (119/1,044) for a median duration of 5 days. For patients with no colonization, MRSA colonization on admission, and ICU-acquired MRSA colonization, respectively, glycopeptide use per 1,000 hospital days was 37.7, 235.2, and 118.3 days. MRSA colonization per se increased by 3.3-fold the use of glycopeptides in MRSA-colonized patients, even when an MRSA infection was not demonstrated, compared to non-colonized patients. Conclusions: In our unit, MRSA colonization greatly increased the risk of S aureus infection and of glycopeptide use in colonized and non-colonized patients, without influencing ICU mortality. MRSA colonization influenced glycopeptide use even if an MRSA infection was not demonstrated; thus, an MRSA control program is warranted to decrease vancomycin use and to limit glycopeptide resistance in gram-positive cocci.

AbstractThe imbalanced production of placental biomarkers and vitamin D deficiency have been proposed as risk factors for the development of preeclampsia (PE). However, little is known about the relationship between them and their role in early- versus late-onset PE. The objectives were to assess the role of 25-hydroxyvitamin D [25(OH)D] concentrations and the soluble fms-like tyrosine kinase 1 (sFlt-1) to placental growth factor (PlGF) ratio in the development of early- and late-onset PE; and to evaluate the relationship between 25(OH)D and the biomarkers.A retrospective, full-blinded cohort study was conducted at the Obstetric Emergency Service of a tertiary care hospital. Pregnant women (n=257) attending obstetric triage with suspicion of PE were included. sFlt-1, PlGF and 25(OH)D concentrations were measured by electrochemoluminescence (ECLIA) immunoassay and pregnancy outcome (development of PE) was registered from patients records.PE women showed lower 25(OH)D concentrations at clinical presentation than non-PE women (median: 35.0 nmol/L and 39.6 nmol/L, respectively; p=0.027). Women with 25(OH)D levels <50 nmol/L experienced an increased risk of developing late-onset PE [odds ratio (OR) 4.6, 95% confidence interval (CI) 1.4–15], but no association was found for early-onset PE. However, a sFlt-1/PlGF ratio above the corresponding cutpoints increased the risk of developing both early- and late-onset PE [ORs 58 (95% CI 11–312) and 12 (95% CI 5.0–27), respectively]. No association was found between 25(OH)D levels and sFlt-1/PlGF ratio.Low vitamin D status in women with suspected late-onset PE increases the risk of imminent development of the disease.
