The impact of outpatient clinical care on the survival and hospitalisation rate in patients with alcoholic liver cirrhosis

In the study, we aimed to determine whether regular outpatient controls in patients with alcoholic liver cirrhosis have an impact on their survival and hospitalisation rates

Helicobacter pylori eradication rates in Slovenia in the period from 2017 to 2019 – data from the European Registry on Helicobacter pylori Management (Hp-EuReg)

International audienceBackground: Helicobacter pylori (H pylori) is the most common chronic bacterial infection in the world, affecting over 50% of the world's population. H pylori is a grade I carcinogen, responsible for the development of 89% of non-cardia gastric cancers. In the present study, we analyzed the data for H pylori eradication treatments in Slovenia after the 3rd National recommendations were implemented.Patients and methods: Slovenia is part of the European Registry on H pylori Management (Hp-EuReg) since the study was launched in 2013. Data were collected at AEG-REDCap e-CRF from September 2017 to December 2019. H pylori eradication treatment was assessed by modified intention-to-treat (mITT) and per-protocol (PP) analyses.Results: Overall, 823 patients from 3 medical institutions were included. Effectiveness with first line 14-day triple therapy with a proton-pomp-inhibitor (PPI), clarithromycin 500 mg, amoxicillin 1000 mg, all BID, was 93% by mITT (714 patients). In patients allergic to penicillin, first line 14-day triple therapy with PPI-clarithromycin-metronidazole achieved 83% effectiveness by mITT (35 patients). Second-line 14-day triple therapy with a PPI-amoxicillin-levofloxacin achieved 89% mITT eradication rate (51 patients). Second-line therapy with the 10-day three-in-one single capsule containing bismuth-tetracycline- metronidazole achieved optimal effectiveness (100% mITT) in 10 patients ( p=0.02).Conclusions: Slovenia is a country with < 15% H pylori resistance to clarithromycin. Triple therapy with a PPI plus two antibiotics during 14 days reported optimal effectiveness (over 90%). Ten-day quadruple bismuth second-line therapy had better results than 14-day triple therapy with levofloxacin)

Differences in the Antigens of Helicobacter pylori Strains Influence on the Innate Immune Response in the In Vitro Experiments

The immune response to Helicobacter pylori importantly determines the pathogenesis of infection as well as the success of antibiotic eradication of the bacteria. Strains of H. pylori were gathered from 14 patients who failed to eradicate H. pylori infection with antibiotics—therapy resistant strains (TRS)—or from patients who were able to eradicate H. pylori infection—therapy susceptible strains (TSS). The THP-1 cells were stimulated with H. pylori antigens. Cathepsin X expression on THP-1 cells and concentration of cytokines in the supernatant of THP-1 cells were measured with a flow cytometer. TSS H. pylori antigens increased the proportion of cathepsin X positive cells compared to TRS H. pylori antigens. TSS H. pylori antigens induced higher secretion of IL-12 and IL-6 compared to TRS H. pylori antigens (P<0.001; 0.02). Polymyxin B, a lipid A inhibitor, lowered the secretion of IL-12 and IL-6 in TRS and TSS. We demonstrated a H. pylori strain-dependent cathepsin X and cytokine expression that can be associated with H. pylori resistance to eradication due to lack of effective immune response. Differences in lipid A of H. pylori might have an influence on the insufficient immune response, especially on phagocytosis
