Background and aims Albumin infusion reduces the incidence of postparacentesis circulatory dysfunction among patients with cirrhosis and tense ascites compared with no treatment. Less costly treatment alternatives such as vasoconstrictors have been investigated, but the results are controversial. Midodrine, an oral α1-adrenergic agonist, increases effective circulating blood volume and renal perfusion by increasing systemic and splanchnic blood pressure. Our aim is to assess whether or not morbidity in terms of renal dysfunction, hyponatremia, systemic, or portal hemodynamics derangement or mortality differed in patients receiving albumin versus midodrine. Patients and methods Seventy-five patients with cirrhosis and refractory ascites were randomized to receive albumin infusion, oral midodrine for 2 days, or oral midodrine for 30 days after therapeutic large volume paracentesis (LVP). The primary endpoints were development of renal impairment or hyponatremia, change in systemic and portal hemodynamics, cost, and mortality in the short-term and long-term follow-up. Results No significant difference was found between groups in the development of renal impairment, hyponatremia, or mortality 6 and 30 days after LVP. A significant increase in 24-h urine sodium excretion was noted in the midodrine 30-day group. Renal perfusion improved significantly with the midodrine intake for 30 days only. The cost of midodrine therapy was significantly lower than albumin. Conclusion Midodrine is as effective as albumin in reducing morbidity and mortality among patients with refractory ascites undergoing LVP at a significantly lower cost. Long-duration midodrine intake can be more useful than shorter duration intake in terms of improvement of renal perfusion and sodium excretion.

Background/Aim:Balloon tamponade has been widely available in emergency situations of acute variceal bleeding. To lessen the complications of Balloon tamponade, a new special type of stent for exclusive use in acute variceal bleeding has been developed. This study aims to investigate the effectiveness and safety of the new self-expandable metal stents (SEMS) in the initial control of acute variceal bleeding. We also hypothesized that using SEMS can bridge the acute bleeding episode converting endoscopic management by sclerotherapy or band ligation to an elective procedure.Patients and Methods:Twenty patients with acute variceal bleeding were included in the study and 16 of them were allocated to receive stent treatment.Results:Stent deployment was successful in 15 of 16 patients (93.75%). Technical errors were reported in 3 (18.75%) patients. Initial control of variceal bleeding was reported in 14 (out of 16) (87.5%) patients. The mean duration of the procedure was 10 (±6) min. Mortality was reported in 4 (25.0%) patients.Conclusion:SEMS is a safe and effective mean to control acute variceal bleeding.

SUMMARYIntroduction: Several genetic mutations affect the first-line triple therapy for Helicobacter pylori. We aimed to study the most common genetic mutations affecting the metronidazole and clarithromycin therapy for H. pylori-infected Egyptian patients.Patients and Methods: In our study, we included 100 successive dyspeptic patients scheduled for diagnosis through upper gastroscopy at Cairo's University Hospital, Egypt. Gastric biopsies were tested for the presence of H. pylori by detection of the 16S rRNA gene. Positive biopsies were further studied for the presence of the rdxA gene deletion by Polymerase Chain Reaction (PCR), while clarithromycin resistance was investigated by the presence of nucleotide substitutions within H. pylori 23S rRNA V domain using MboII and BsaI to carry out a Restricted Fragment Length Polymorphism (RFLP) assay.Results: Among 70 H. pylori positive biopsies, the rdxA gene deletion was detected in 44/70 (62.9%) samples, while predominance of the A2142G mutations within the H. pylori 23S rRNA V domain was evidenced in 39/70 (55.7%) of the positive H. pylori cases. No statistically significant difference was found between the presence of gene mutations and different factors such as patients 'age, gender, geographic distribution, symptoms and endoscopic findings.Conclusion: Infection with mutated H. pylori strains is considerably high, a finding that imposes care in the use of the triple therapy to treat H. pylori in Egypt, since the guidelines recommend to abandon the standard triple therapy when the primary clarithromycin resistance rate is over 20%1.

Research is continuous for noninvasive tools for the prediction of portal hypertension than upper gastrointestinal endoscopy. Serum sCD163 correlates with hepatic venous pressure gradient, aiding in the prediction of portal hypertension. We aimed at investigating the role of sCD163 in the prediction of the presence and size of varices as well as a stratification tool for surveillance or prophylaxis by assessment of prognosis and risk of bleeding. Two hundred forty-three cirrhotic patients were divided into 3 groups: group I: no varices, group II: small-sized varices, and group III: medium-sized and large-sized varices. Serum sCD163 levels were assessed and correlated with abdominal ultrasound and laboratory investigations. Follow-up for 1 year was conducted to assess the risk of bleeding, and band ligation was performed for significant varices with follow-up of obliteration. sCD163 levels were significantly higher in patients with varices requiring prophylactic interventions (P = 0.03) and in large varices (P = 0.012), patients at risk of bleeding (P = 0.04), and the bleeder patients (P = 0.001). No relationship between the sCD163 levels and the rate of variceal obliteration was reported. sCD163 levels were positively correlated with the Child score (P = 0.05), the portal vein diameter (P = 0.02), and the splenic size (P = 0.04). Although sCD163 level cannot predict the development of varices, it serves as a good predictor for the detection of size of varices (large varices), the need of prophylactic interventions, and risk of variceal bleeding. sCD163 level is a helpful indicator with the progression of cirrhosis and portal hypertension.
