Helicobacter pylori is one of the most commonly seen bacterium worldwide. It's in the etiology of multiple gastrointestinal diseases, ranging from gastritis to gastric carcinoma. The antimicrobial therapies, which are frequently prescribed empirically, are losing their effectivity as a result of the increasing antimicrobial resistance. As the standard triple therapy is now left especially in areas with high-clarithromycin resistance due to decreased eradication rates, quadruple therapies are recommended in most regions of the world. Alternatively, concomitant, sequential and hybrid therapies are used. There is still a debate going on about the use of levofloxacin-based therapy in order to prevent the increase in quinolone resistance. If no regimen can achieve the desired eradication rate, culture-guided individualized therapies are highly recommended. Probiotics, statins and n-acetylcysteine are helpful as adjuvant therapies in order to increase the effectiveness of the eradication therapy. Herein, we focused on different eradication regimens in order to highlight the current Helicobacter pylori treatment.

Highlights of the Study • Severity of chronic inflammation, where bacterial density is the highest, was found as the most effective criteria for eradication. • The presence of intestinal metaplasia (IM) and atrophy requires only an absolute treatment. • The presence of IM is not a decisive criterion for the success of the standard triple therapy.

Aim: Rapid prediction of prognosis is helpful in reflecting the disease severity and patient mortality. This is especially important in critically ill elderly patients who have high mortality risk. This study aimed to investigate the effects of admission laboratory results and medical histories on the prediction of prognosis in critically ill elderly patients. Material and Methods: Patients who were ≥65 years and admitted to a medical intensive care unit (ICU) between 2011 and 2013 were retrospectively analyzed. Results: The study included 449 patients and mortality rate was 47.4%. Nonsurvivors had lower pH, HCO 3 and albumin levels, and lower hematocrit and platelet counts, but higher aspartate aminotransferase, alanine aminotransferase, C-reactive protein (CRP), creatinine, phosphorus, magnesium and bilirubin levels, and higher leukocyte count than survivors. The rates of chronic kidney disease, being in a bedridden state and having cardiopulmonary resuscitation (CPR) before ICU admission were significantly high in nonsurvivors. Multivariate analysis showed that pH <7.20, albumin ≤2 gr/dL, low hematocrit and high CRP levels, high leukocyte count, bedridden state, and CPR were mortality predictors. After including the admission diagnoses and endotracheal intubation into the model, pH <7.20 (odds ratio [OR], 4.31; 95% confidence interval [CI], 1.59-11.70), albumin ≤2 gr/dL (OR, 3.61; 95% CI, 0.99-13.03), hematocrit level (OR, 0.94; 95% CI, 0.91-0.99) and leukocyte count (OR 1.06; 95% CI, 1.01-1.11) retained their prognostic importance for mortality. Conclusions: Severe acidemia, low albumin and hematocrit levels, and high leukocyte count at admission help clinicians to foresee the prognosis in severely ill elderly patients. They keep their importance even in the presence of other fundamental mortality predictors.
