Serum oxidative stress is increased in patients with post cholecystectomy bile duct injury

Background: post-cholecystectomy bile duct injuries are identified by the onset of jaundice as well as elevated bilirubin and alkaline phosphatase levels during the peri-operative period. It is unknown how serum oxidative stress markers are modified in patients with post-cholecystectomy bile duct injuries. Objective: to determine serum oxidative stress marker levels (lipid peroxidation by-products, nitrites/nitrates and total antioxidant capacity) in patients with post-cholecystectomy bile duct injuries. Patients and methods: a prospective, transversal and analytical study was designed with two groups. Group 1: 5 healthy volunteer subjects. Group 2: 52 patients with post-cholecystectomy bile duct injuries (43 female and 9 male). An elective bilio-digestive reconstruction was performed at week 8. The serum oxidative stress marker levels were quantified by colorimetric method. Results: patients with bile duct injuries had a significant increased serum lipid peroxides (malondialdehyde and 4-hydroxyalkenals) and nitric oxide metabolites (nitrites/nitrates) levels compared to the control group. In contrast, total antioxidant capacity in patients with bile duct injuries remained similar compared to healthy controls. Conclusions: the results show that oxidative stress is usually associated to bile duct injury. © 2010 ARÁN EDICIONES, S. L

Tumor necrosis factor-alpha and interleukin-6 levels among patients suffering a bile duct injury during cholecystectomy [El comportamiento del factor de necrosis tumoral alfa e interleucina 6 en lesiones de v�as biliares postcolecistectom�a]

Background: During cholecystectomy, the bile duct may be injured. When this complication occurs, Kupffer cells are activated and produce tumor necrosis factor alpha (TNF-a) and interleukin-6 (IL6) to phagocyte toxic products Aim: To measure serum levels of TNF-a and IL-6 among patients that suffered a bile duct injury after a cholecystectomy. Patients and Methods: Serum levels of TNF-a and IL-6 were measured prior to the bile-enteric derivation and after one year of follow-up, in 31 patients that had a complete bile duct obstruction after open or laparoscopic cholecystectomy and in 5 healthy controls. Results: At baseline TNF-a levels in healthy subjects and patients with bile duct injury were 0 and 43.9 � 2.9 ng/mL, respectively (p < 0.01). At one year of follow up, TNF-a became undetectable among patients. At baseline, the values for IL-6 among healthy controls and patients were 3.0 � 2.0 and 72.0 � 94.7 pg/mL respectively, (p < 0,004). After one year of follow up, IL-6 levels decreased to 6.4 � 0.3 pg/mL among patients. Conclusions: TNF-a and IL-6 levels were elevated before bile-enteric derivation among patients with bile duct injury and became normal one year later

At one year of follow up, TNF-a became undetectable among patients.

Anticoagulant selection in relation to the SAMe-TT2R2 score in patients with atrial fibrillation: The GLORIA-AF registry

Aim: The SAMe-TT2R2 score helps identify patients with atrial fibrillation (AF) likely to have poor anticoagulation control during anticoagulation with vitamin K antagonists (VKA) and those with scores &gt;2 might be better managed with a target-specific oral anticoagulant (NOAC). We hypothesized that in clinical practice, VKAs may be prescribed less frequently to patients with AF and SAMe-TT2R2 scores &gt;2 than to patients with lower scores. Methods and results: We analyzed the Phase III dataset of the Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation (GLORIA-AF), a large, global, prospective global registry of patients with newly diagnosed AF and ≥1 stroke risk factor. We compared baseline clinical characteristics and antithrombotic prescriptions to determine the probability of the VKA prescription among anticoagulated patients with the baseline SAMe-TT2R2 score &gt;2 and ≤ 2. Among 17,465 anticoagulated patients with AF, 4,828 (27.6%) patients were prescribed VKA and 12,637 (72.4%) patients an NOAC: 11,884 (68.0%) patients had SAMe-TT2R2 scores 0-2 and 5,581 (32.0%) patients had scores &gt;2. The proportion of patients prescribed VKA was 28.0% among patients with SAMe-TT2R2 scores &gt;2 and 27.5% in those with scores ≤2. Conclusions: The lack of a clear association between the SAMe-TT2R2 score and anticoagulant selection may be attributed to the relative efficacy and safety profiles between NOACs and VKAs as well as to the absence of trial evidence that an SAMe-TT2R2-guided strategy for the selection of the type of anticoagulation in NVAF patients has an impact on clinical outcomes of efficacy and safety. The latter hypothesis is currently being tested in a randomized controlled trial.
