CYP1A2 -163A/A genotype influence carbamazepine pharmacokinetics. In addition to sex and total carbamazepine daily dose, -163C > A CYP1A2 polymorphism should be considered as a predictor of carbamazepine clearance.
Purpose We aimed to determine the association of two of the most important functional polymorphisms of IL-8 and IL-10 with the clinical course and outcome of acute pancreatitis. Method Ninety-three patients with acute pancreatitis were genotyped for IL-8-251T>A and IL-10-1082G>A using PCR-RFLP. The severity of the disease was determined based on the Atlanta Classification system. Results In patients treated with opioids, the odds for severe form of acute pancreatitis, its complications, and death were increased. Advanced age was associated with higher odds of organ/multiple organ failure and other systemic complications. Multivariate logistic regression analyses confirmed the observed effect of age and use of opioids, and revealed higher odds for the development of severe form of acute pancreatitis [P = 0.017, odds ratio (OR): 4.324, 95% confidence interval (CI): 1.305–14.323], its complications in general (P = 0.011, OR: 4.936, 95% CI: 1.442–16.897), pancreatic necrosis (P = 0.032, OR: 3.922, 95% CI: 1.122–13.707) and systemic inflammatory response syndrome (P = 0.037, OR: 3.838, 95% CI: 1.085–13.583) in the absence of IL-10-1082G>A variant allele. The effect of IL-8 -251T>A on acute pancreatitis severity or mortality was not detected. Conclusion Our study suggests the IL-10 -1082A allele as a protective factor in acute pancreatitis. Opioid analgesics treatment in acute pancreatitis is associated with severity, complications and mortality, while advanced age increases the risk of systemic complications.
Background/Aim. Acute pancreatitis is an inflammatory condition having the significant mortality rate in the case of severe forms of the disease. The aim of this study was to investigate putative factors of increased mortality in patients with acute pancreatitis with contradictory prior evidence, and to reveal factors that were insufficiently explored previously. Methods. This prospective cohort study with nested case/control design included all adult patients treated for acute pancreatitis in the Clinical Center of Kragujevac, Serbia, during the 3-year period (from October 2011 to December 2014). The cases (n = 19) were patients who died, while the controls (n = 113) were patients who survived. The associations between putative risk factors and the study outcomes were tested by univariate and multivariate logistic regressions, and expressed as crude and adjusted odds ratios (OR) with corresponding 95% confidence intervals (CI). Results. Significant association with the lethal outcome in acute pan-creatitis was found for advanced age (adjusted OR 1.12, 95%CI 1.02-1.23), presence of significant comorbidities (adjusted OR 10.62, 95%CI 1.01-111.39), higher interleukin-8 (IL-8) value on third day from onset of symptoms (adjusted OR 1.05, 95%CI 1.02-1.08), use of tramadol and/or morphine (adjusted OR 47.34, 95%CI 3.21-699.08), the Bedside index for severity in acute pancreatitis (BISAP) score ≥ 3 in the first 24 hours (adjusted OR 48.11, 95%CI 3.14-736.29), and prophylactic use of antibiotics (adjusted OR 0.07, 95%CI 0.01-0.85). Conclusion. Advanced age, significant comorbidities, use of tramadol and/or morphine and more severe disease as assessed by BISAP score can increase the risk of death in acute pancreatitis, while prophylactic use of antibiotics may have a protective role.
Carbamazepine exhibits significant inter-individual variability in its efficacy
Histamine is a biogen amin, which is formed by decarboxylation of the histidine amino acid, under the action of the L-histidine-decarboxylase enzyme. High level of free histidine in fish meat, bacterial histidin decarboxylase activity and high temperature of storage elevate the level of histamine. Among the most important factors that can affect the level of histamine in fish meat are the type of fish and the method of its preservation. In order to determine this dependence, 1030 samples of frozen fish (tuna, mackerel, sardines and sprat) and 167 samples of canned fish (tuna, sardines and mackerel) were monitored for histamine content by ELISA method. It was determined a lower concentration of histamine in frozen fish (from 5.71 mg/kg to 18.03 mg/kg) compared to canned fish (from 15.03 mg/kg to 110.6 mg/kg). The highest histamine concentrations were found in the mackerel samples, regardless of the preservation method (110.6 mg/kg in canned mackerel and 18.03 mg/kg in frozen mackerel), which were significantly higher compared to the histamine levels found in cans of tuna and sardines (p ˂0.0001). Of the total number of samples, three samples (two samples of canned sardines and one sample of canned mackerel) were declared unsafe for human health. In most of the analyzed samples, the level of determined histamine was relatively low, which confirms adequate implementation of control protocols and efficant surveillance of products placed on the Serbian market.
