Summary: Gastric cancer remains a global health problem, and Chile has one of the highest GC mortality rates in the region. Helicobacter pylori (H. pylori) infection is ubiquitous in Chilean adults, and it constitutes the main cause of GC worldwide. A long-term process occurs from premalignant lesions to carcinoma. H. pylori eradication during early stages of disease significantly impacts outcomes, favorin...

Summary: The primary objective of the REACT randomized clinical trial (RCT) is to optimize the clinical benefit from adjunctive clarithromycin treatment shown in the ACCESS trial and to provide evidence for the clinical benefit of early start of adjunctive oral clarithromycin guided by suPAR to prevent the progression into sepsis in patients with community-acquired pneumonia (CAP) at risk. This can be achi...

Summary: Bronchiectasis is a chronic inflammatory respiratory disease defined as the irreversible dilatation of one or more bronchi and is associated with chronic and frequently purulent expectoration, multiple exacerbations and progressive dyspnea. Bronchiectasis has a large heterogeneity. Different patients with bronchiectasis may have different etiology, clinical manifestations, and imaging features. Pr...

Summary: Helicobacter pylori infection is a widespread bacterial disease affecting nearly half of the world's population. In children, the infection displays distinct features versus adults, with lower prevalence, variable symptoms, and differing endoscopic and histological appearances. Typically acquired in early childhood, its transmission is closely linked to socio-economic disadvantage and overcrowding...

Summary: Treatment of Mycobacterium xenopi (MX) lung disease is not-well- tolerated and concerned a growing number of patients, especially with chronic pulmonary diseases or immunosuppression. The outcome of these patients is poor, and treatment is very long. Indeed, this duration is based on the date of sputum conversion. Treatment should be continued until 12 months after sputum conversion. In the vast m...

Summary: MAC lung infections are a growing public health problem. The ATS / IDSA 2007 guidelines for the treatment of these non-tuberculous mycobacterial infections recommend the use of a macrolide or azalide (clarithromycin or azithromycin), rifampicin or rifabutin and ethambutol. For MAC disseminated infections, several studies have compared combinations containing clarithromycin or azithromycin and foun...

Summary: H. pylori is an infection of the stomach that can cause chronic gastritis, gastric cancer and peptic ulcer disease. The goal of this study is to screen people for this infection and offer treatment for those who test positive for the infection. By treating those who are positive for H. pylori, there is an opportunity to prevent gastritis, peptic ulcer disease, and even gastric cancer.

Summary: This study will independently assess the efficacy and safety of 11 combination therapies in 12 arms, in dose-escalation/-evaluation and expansion phases, for the treatment of patients with relapsed/refractory multiple myeloma (RRMM) and newly diagnosed multiple myeloma (NDMM). The combinations to be evaluated are: * Arm 1: Selinexor + dexamethasone + pomalidomide (SPd); enrollment complete * Arm 2...

Summary: The prevalence of H. pylori antibiotic resistance has reached an alarming level worldwide. Antibiotic stewardship programs should be urgently developed and implemented. However, H. pylori antimicrobial susceptibility testing (AST) is rarely offered, making local resistance patterns not easily available. Guideline-recommended empiric therapies (GR-ET) may no longer reliably achieve high cure rate i...

Summary: To conduct an unblinded pragmatic randomized controlled trial (pRCT) Improvement of PPROM Management with Prophylactic Antimicrobial Therapy (iPROMPT) of a seven-day course of ceftriaxone, clarithromycin, and metronidazole versus the current standard of care of a seven-day course of ampicillin/amoxicillin and azithromycin or erythromycin to prolong pregnancy and decrease adverse perinatal outcomes...

Methods: This will be a multi-center, open labeled trial Patients: 360 patients with failure to H. pylori eradication for at least two times will be enrolled Determination of antibiotic resistance of H. pylori: Agar dilution test will be used to determine the minimum inhibitory concentrations of levofloxacin, tetracycline, rifabutin, and clarithromycin to guide the selection of antibiotics. Treatment regim...

Summary: Current first-line Helicobacter pylori eradication protocols involve multidrug regimens comprising a proton pump inhibitor (PPI) or bismuth agent combined with dual antibiotics (e.g., clarithromycin, amoxicillin, quinolones, furazolidone, nitroimidazoles, or tetracycline) administered for 7-14 days. In China, the bismuth-containing quadruple therapy (BQT) remains the standard first-line treatment ...
