Vitamin A treatment for severe sepsis in humans; a prospective randomized double blind placebo-controlled clinical trial.

ABSTRACT: PURPOSE:To test the benefits of Vitamin A treatment in patients with sepsis on length of time in ICU, days on ventilator, days on intravenous blood pressure support and 28-day mortality. The trial was prospective, randomized and double-blind. As part of a larger sepsis trial, 63 patients with sepsis were randomized to receive either 100,000 IU of Vitamin A intramuscular or placebo over 7-days. Data analysis was by ANOVA with two tailed test and p < 0.05 as significant. RESULTS:The mean age was 51 ± 2 (mean ± SEM) with 54% female. Groups were well matched with regards to APACHE III score, WBC count, and incidence of bacteremia. In addition, all patients had an ACTH stimulation test using 250 mcg of ACTH IV and serum cortisol was measured at time 0, 30 and 60 min. Baseline cortisol of 24.6 ± 1 mg/dl increased to 41 ± 2 mg/dl at 30 min and 49 ± 2 at 60 min. There was no significant difference between the groups. All cortisol responses were greater than 11.9 mg/dl. Serum Vitamin A level was below normal in 54% of the patients. After randomization, 100,000 IU of Vitamin A daily was given to 32 patients and blinded placebo was given daily to 32 patients for seven days. This was administered as a 1 cc injection of either medication or placebo and was blinded from all but the research pharmacist. The number of days in the ICU was slightly, but not significantly reduced (p = 0.39) by approximately 2 days in the Vitamin A treated patients. The average number of days on blood pressure agents and the day on ventilator were similar. The 28-day mortality rates were similar between the two groups (28 vs 34% placebo vs Vitamin A group). Seven days of high dose intramuscular Vitamin A treatment in patients with sepsis where approximately 50% were vitamin A deficient had no benefit in adults with sepsis.

Project description:BACKGROUND:Sepsis accounts for 30% to 50% of all in-hospital deaths in the United States. Other than antibiotics and source control, management strategies are largely supportive with fluid resuscitation and respiratory, renal, and circulatory support. Intravenous vitamin C in conjunction with thiamine and hydrocortisone has recently been suggested to improve outcomes in patients with sepsis in a single-center before-and-after study. However, before this therapeutic strategy is adopted, a rigorous assessment of its efficacy is needed. METHODS:The Vitamin C, Thiamine and Steroids in Sepsis (VICTAS) trial is a prospective, multi-center, double-blind, adaptive sample size, randomized, placebo-controlled trial. It will enroll patients with sepsis causing respiratory or circulatory compromise or both. Patients will be randomly assigned (1:1) to receive intravenous vitamin C (1.5?g), thiamine (100?mg), and hydrocortisone (50?mg) every 6 h or matching placebos until a total of 16 administrations have been completed or intensive care unit discharge occurs (whichever is first). Patients randomly assigned to the comparator group are permitted to receive open-label stress-dose steroids at the discretion of the treating clinical team. The primary outcome is consecutive days free of ventilator and vasopressor support (VVFDs) in the 30?days following randomization. The key secondary outcome is mortality at 30?days. Sample size will be determined adaptively by using interim analyses with pre-stated stopping rules to allow the early recognition of a large mortality benefit if one exists and to refocus on the more sensitive outcome of VVFDs if an early large mortality benefit is not observed. DISCUSSION:VICTAS is a large, multi-center, double-blind, adaptive sample size, randomized, placebo-controlled trial that will test the efficacy of vitamin C, thiamine, and hydrocortisone as a combined therapy in patients with respiratory or circulatory dysfunction (or both) resulting from sepsis. Because the components of this therapy are inexpensive and readily available and have very favorable risk profiles, demonstrated efficacy would have immediate implications for the management of sepsis worldwide.

Project description:IntroductionTo evaluate whether alkaline phosphatase (AP) treatment improves renal function in sepsis-induced acute kidney injury (AKI), a prospective, double-blind, randomized, placebo-controlled study in critically ill patients with severe sepsis or septic shock with evidence of AKI was performed.MethodsThirty-six adult patients with severe sepsis or septic shock according to Systemic Inflammatory Response Syndrome criteria and renal injury defined according to the AKI Network criteria were included. Dialysis intervention was standardized according to Acute Dialysis Quality Initiative consensus. Intravenous infusion of alkaline phosphatase (bolus injection of 67.5 U/kg body weight followed by continuous infusion of 132.5 U/kg/24 h for 48 hours, or placebo) starting within 48 hours of AKI onset and followed up to 28 days post-treatment. The primary outcome variable was progress in renal function variables (endogenous creatinine clearance, requirement and duration of renal replacement therapy, RRT) after 28 days. The secondary outcome variables included changes in circulating inflammatory mediators, urinary excretion of biomarkers of tubular injury, and safety.ResultsThere was a significant (P=0.02) difference in favor of AP treatment relative to controls for the primary outcome variable. Individual renal parameters showed that endogenous creatinine clearance (baseline to Day 28) was significantly higher in the treated group relative to placebo (from 50±27 to 108±73 mL/minute (mean±SEM) for the AP group; and from 40±37 to 65±30 mL/minute for placebo; P=0.01). Reductions in RRT requirement and duration did not reach significance. The results in renal parameters were supported by significantly more pronounced reductions in the systemic markers C-reactive protein, Interleukin-6, LPS-binding protein and in the urinary excretion of Kidney Injury Molecule-1 and Interleukin-18 in AP-treated patients relative to placebo. The Drug Safety Monitoring Board did not raise any issues throughout the trial.ConclusionsThe improvements in renal function suggest alkaline phosphatase is a promising new treatment for patients with severe sepsis or septic shock with AKI.Trial registrationwww.clinicaltrials.gov: NCT00511186.

Project description:We previously found decreased levels of Coenzyme Q10 (CoQ10) in patients with septic shock. The objective of the current study was to assess whether the provision of exogenous ubiquinol (the reduced form of CoQ10) could increase plasma CoQ10 levels and improve mitochondrial function.We performed a randomized, double-blind, pilot trial at a single, tertiary care hospital. Adults (age ?18 years) with severe sepsis or septic shock between November 2012 and January 2014 were included. Patients received 200 mg enteral ubiquinol or placebo twice a day for up to seven days. Blood draws were obtained at baseline (0 h), 12, 24, 48, and 72 h. The primary outcome of the study was change in plasma CoQ10 parameters (total CoQ10 levels, CoQ10 levels relative to cholesterol levels, and levels of oxidized and reduced CoQ10). Secondary outcomes included assessment of: 1) vascular endothelial biomarkers, 2) inflammatory biomarkers, 3) biomarkers related to mitochondrial injury including cytochrome c levels, and 4) clinical outcomes. CoQ10 levels and biomarkers were compared between groups using repeated measures models.We enrolled 38 patients: 19 in the CoQ10 group and 19 in the placebo group. The mean patient age was 62?±?16 years and 47% were female. Baseline characteristics and CoQ10 levels were similar for both groups. There was a significant increase in total CoQ10 levels, CoQ10 levels relative to cholesterol levels, and levels of oxidized and reduced CoQ10 in the ubiquinol group compared to the placebo group. We found no difference between the two groups in any of the secondary outcomes.In this pilot trial we showed that plasma CoQ10 levels could be increased in patients with severe sepsis or septic shock, with the administration of oral ubiquinol. Further research is needed to address whether ubiquinol administration can result in improved clinical outcomes in this patient population.Clinicaltrials.gov identifier NCT01948063.

Project description:Hops are the main components of beer that provide flavor and bitterness. Iso-α-acids, the bitter components of beer, have been reported to reduce body fat in humans, but the bitterness induced by effective doses of iso-α-acids precludes their acceptance as a nutrient. The matured hop bitter acids (MHBA) of oxidized hops appear to have a more pleasant bitterness compared to the sharper bitterness of iso-α-acids. While there has been little information concerning the identity of the MHBA compounds and their physiological effects, MHBA was recently found to be primarily composed of oxides derived from α-acids, and structurally similar to iso-α-acids. Here, we investigated the effects of matured hop extract (MHE) containing MHBA on reducing abdominal body fat in healthy subjects with a body mass index (BMI) of 25 to below 30 kg/m(2), classified as "obese level 1" in Japan or as "overweight" by the WHO.A randomized, double-blind, placebo-controlled parallel group study.Two hundred subjects (male and female aged 20 to below 65 years with a BMI of 25 or more and less than 30 kg/m(2)) were randomly assigned to two groups. During a 12-week ingestion period, the subjects in each group ingested daily 350 mL of test-beverage, either containing MHE (with 35 mg MHBA), i.e. the namely active beverage, or a placebo beverage without MHE. The primary endpoint was reduction of the abdominal fat area as determined by CT scanning after continual ingestion of MHE for 12 weeks.Compared to the placebo group, a significant reduction was observed in the visceral fat area after 8 and 12 w, and in the total fat area after 12 w in the active group. There was also a concomitant decrease in body fat ratio in the active group compared to the placebo group. No adverse events related to the test beverages or clinically relevant abnormal changes in the circulatory, blood and urine parameters were observed in either group.The present study suggests that continual ingestion of MHE safely reduces body fat, particularly the abdominal visceral fat of healthy overweight subjects.UMIN-CTR UMIN000014185.
