The effect of probiotics on gut flora, level of endotoxin and Child–pugh score in cirrhotic patients: results of a double-blind randomized study

Objective To determine the effect of Escherichia coli Nissle (Mutaflor, Ardeypharm GmbH, Herdecke, Germany) on the intestinal colonization, level of endotoxin and liver functions in patients with liver cirrhosis. Methods Thirty-nine patients with liver cirrhosis diagnosed by means of biopsy and clinical examinations were randomly allocated to treatment with E. coli Nissle or placebo for 42 days. Standard clinical examination, biochemical and hematological examinations, level of endotoxin and microbiological examination of the stool were performed before and after the treatment. Results In comparing the treatment of E. coli Nissle and placebo, significant improvement of the intestinal colonization (P<0.001) in the E. coli Nissle group was described. We found a trend of significant lowering of the endotoxemia (P=0.07) and improvement of liver functions evaluated by Child–Pugh score (P=0.06). Conclusion E. coli Nissle seems to be effective in the restoration of normal colonic colonization and can probably lower endotoxemia in cirrhotic patients.

Combined treatment of achalasia – botulinum toxin injection followed by pneumatic dilatation: long‐term results

Injection of botulinum toxin (BT) and pneumatic dilatation are available methods in nonsurgical treatment of achalasia. Authors anticipate beneficial effect of prior BT injection on the success of pneumatic dilatation and duration of its effect. There are no long-term data available to assess efficacy of combined treatment. From 1998 to 2007, 51 consecutive patients (20 men and 31 women, age 24-83) with achalasia were included and prospectively followed up. Each patient received injection of 200 IU of BT into the lower esophageal sphincter (LES) during endoscopy and 8 days later pneumatic dilatation (PD) under X-ray control was performed. The follow-up was established every 3 months first year and then annually. The efficacy was evaluated by a questionnaire concerning patients symptoms and manometry. Results were compared with 40 historical controls (16 men and 24 women, age 26-80) treated by PD alone using the same method and follow-up. Fifty-one patients underwent combined treatment. Four patients failed in follow-up and were not included for analysis. The mean duration of follow-up was 48 months with range 12-96 months. Thirty-four of forty-seven (72%) patients were satisfied with results with none or very rare and mild troubles at the time of the last visit. Forty-one patients were followed up more than 2 years. Effect of therapy lasted in 75% (31/41) of them. In 17 patients, more than 5 years after treatment, effect lasted in 12 (70%). Mean tonus of LES before therapy was 29 mm Hg (10-80), 3 months after therapy decreased to 14 mmHg (5-26). The cumulative 5 years remission rate (+/-95% CI) in combined treated patients 69% +/- 8% was higher than in controls 50% +/- 9%; however it, was not statistically significant (P= 0.07). In control group 1, case of perforation (2.5%) occurred. Eight patients (17%) with relapse of dysphagia were referred to laparoscopic Heller myotomy with no surgical complication. The main adverse effect was heartburn that appeared in 17 patients (36%). Initial injection of BT followed by PD seems to be effective for long-term results with fewer complications. But the combined therapy is not significantly superior to PD alone.

Variceal bleeding in portal hypertension: bacterial infection and comparison of efficacy of intravenous and per-oral application of antibiotics--a randomized trial.

Objective To determine the prevalence of bacterial infection in patients admitted to hospital with variceal bleeding in comparison with patients with liver cirrhosis admitted because of another reason. To compare the effect of orally administered antibiotics vs. intravenous antibiotics. Methods Bacteriological investigation of blood culture, urine, throat smear, perianal smear and ascites (polymorphonuclear count as well in ascites) was made in 46 cirrhotic patients admitted to hospital with variceal bleeding and 48 cirrhotic patients admitted because of another reason. Bleeders were treated endoscopically (sclerotization) and pharmacologically (terlipressin 1 mg every 4 h for 5 days), and were randomly allocated to the treatment with oral norfloxacin (25 patients) or intravenous ampicillin/sulbactam (21 patients). Early and late mortalities were evaluated. Results The incidence of infection was high in both groups (63.0% bleeders vs. 54.2% controls), but bleeding patients more often had positive blood culture (17.3% vs. 8.6%) and statistically significantly more positive findings in the throat smears (36.9% vs. 17.3%, P=0.04), which gives the evidence of increased pathological colonization in these patients. No difference in survival was seen in patients with per-oral or intravenous administration of antibiotics. Conclusion Bacterial infection was demonstrated in high percentage in patients with liver cirrhosis admitted to hospital. The administration of antibiotics is indicated in these patients. Intravenous application is probably of the same efficacy as per-oral one.

It encompasses a rare, primary motor disorder of the distal esophagus. Methods Over the period 1998-2006, 115 patients underwent various treatments for achalasia; the subgroup of seniors consisted of 26 patients. Six patients of these (age 69.7 y) underwent a modified Heller cardiomyotomy due to failure of previous endoscopic interventions. Standard esophageal manometry and 24 hour pH metry were performed pre- and postoperatively. Results Six senior patients with achalasia underwent a laparoscopic Heller myotomy. Average preoperative tonus of the LES was 55 mmHg, postoperative tonus of the LES decreased to 11 mmHg. We performed Toupet partial fundoplication in all patients; no microperforation of the esophagus was found in the preoperative esophagoscopy. We recorded minimal pathological gastroesophageal reflux in pH metry – the average preoperative DeMeester score was 8, postoperatively 10.5. Prolonged dysphagia was not present in any patient – preoperative GIQLI score was 94, postoperative score was 106. There was no mortality or morbidity in the group of the operated patients. Conclusion Our operational results and postoperative follow-up show that laparoscopic Heller myotomy with Toupet partial fundoplication is a safe and effective treatment and can be recommended as the method of first choice for senior patients with no contraindication for laparoscopic operation.

The Use of Biomarkers in Early Diagnostics of Pancreatic Cancer

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal solid malignancies with increasing incidence. The poor prognosis is due to the aggressive nature of the tumor, late detection, and the resistance to chemotherapy and radiotherapy. A radical surgery procedure is the only treatment that has been shown to improve the 5-year survival rate to 20-25%. However, the majority of patients (80-85%) are diagnosed with locally advanced or metastatic disease and just 15-20% patients are diagnosed in an early stage allowing them to undergo the potentially curative surgical resection. The early detection of PDAC without the use of invasive methods is challenging and discovery of a cost-effective biomarker with high specificity and sensitivity could significantly improve the treatment and survival in these patients. In this review, we summarize current and newly examined biomarkers in early PDAC detection.

Qualitative Evaluation of the Composition of Refluxate by 24-Hour Multichannel Esophageal Intraluminal Impedance and pH-Monitoring and its Relationship to Extraesophageal Reflux Disease

We presented a study focused on qualitative evaluation of the composition of refluxate and its relationship with extraesophageal symptoms. Gastroesophageal reflux disease (GERD) is a disease caused by backflow of gastric contents into the esophagus due to the failure of physiological antireflux mechanisms and can lead to esophageal and extraesophageal symptomatology. Extraesophageal reflux (EER) is a condition where refluxate penetrate above the upper esophageal sphincter (UES) in to the oral cavity, pharynx, upper and lower respiratory tract and leads to pathological changes. The examinations in our study were carried out using 24-hour multichannel intraluminal impedance and pH esophageal monitoring (MII-pH), which compared to the more commonly used conventional pH-monitoring can accurately detect reflux episodes at all pH levels and divide the episodes to acid reflux, weakly acidic reflux and nonacid reflux, and also provides information of the composition of refluxate (liquid, gas and mixture). We evaluated results of the examinations from 200 patients in two groups. The first group included 100 patients with classic GERD and in the second group were 100 patients with EER symptoms. We evaluated DeMeester score, the number of reflux episodes by pH, simultaneously the state of matter and the rate of penetration in the UES area. Patients with EER symptoms have more weakly acid reflux episodes and fewer acid reflux episodes compared to a group of patients with classical GERD symptoms while we found minor differences in the frequency of individual components of refluxate. In the group with EER we also observed lower values of DeMeester score, a higher number of gaseous reflux episodes and generally significantly higher number of penetration of refluxate of all states of matter to the UES area.

The optimal bowel preparation intervals before colonoscopy: A randomized study comparing polyethylene glycol and low-volume solutions

BACKGROUND & AIMS The optimal duration of bowel preparation has only been assessed for polyethylene glycol (PEG). The aim of the study was to determine the intervals for achieving a satisfactory quality/tolerability of the preparation using PEG/ascorbic acid (PEGA) and sodium picosulphate/magnesium citrate (SPMC), and to compare them with 4L of PEG. METHODS A randomized, endoscopist-blinded, multicentre study. The 612 outpatients referred to a colonoscopy, were prepared using PEG, SPMC, PEGA. The quality, tolerability, duration of the preparation, and the interval from the end of the preparation to the colonoscopy was assessed. RESULTS Optimum duration of the preparation was similar for both PEG and SPMC (≥7.3 vs. ≥8.8 h, overall ≥8.4 h). Optimum interval to the colonoscopy was ≤11.8 h and did not differ between preparations (PEG, PEGA ≤ 11.8, SPMC ≤ 13.3 h). These times were the only predictors for a satisfactory preparation. The tolerability depends on the product type (SPMC) only. Timing of the preparation or the other factors had no impact on tolerability. CONCLUSION The optimum intervals for bowel preparation are identical for all preparations. Satisfactory preparation is achived at the preparation length ≥8.4 h and the time to colonoscopy ≤11.8 h.

Different clinical utility of oropharyngeal bacterial screening prior to percutaneous endoscopic gastrostomy in oncological and neurological patients.

Background. The aim of this study was to monitor oropharyngeal bacterial colonization in patients indicated for percutaneous endoscopic gastronomy (PEG). Methods. Oropharyngeal swabs were obtained from patients prior to PEG placement. A development of peristomal infection was evaluated. The analysis of oropharyngeal and peristomal site pathogens was done. Results. Consecutive 274 patients referred for PEG due to neurological disorder or cancer completed the study. Oropharyngeal colonization with pathogens was observed in 69% (190/274), dominantly in the neurologic subgroup of patients (P < 0.001). Peristomal infection occurred in 30 (10.9%) of patients and in 57% of them the correlation between oropharyngeal and peristomal agents was present. The presence of oropharyngeal pathogens was assessed as an important risk factor for the development of peristomal infection only in oncological patients (OR = 8.33, 95% CI: 1.66–41.76). Despite a high prevalence of pathogens in neurological patients, it did not influence the risk of peristomal infection with the exception for methicillin resistant Staphylococcus aureus (MRSA) carriers (OR 4.5, 95% CI: 1.08–18.76). Conclusion. During oropharyngeal microbial screening prior to the PEG insertion, the detection of pathogens may be a marker of the increased risk of peristomal infection in cancer patients only. In neurological patients the benefit of the screening is limited to the detection of MRSA carriers.
