- Standard Triple Therapy versus Sequential Therapy in Helicobacter pylori Eradication: A Double-Blind, Randomized, and Controlled Trial(2015) EISIG, Jaime Natan; NAVARRO-RODRIGUEZ, Tomas; TEIXEIRA, Ana Cristina Sa; SILVA, Fernando Marcuz; MATTAR, Rejane; CHINZON, Decio; HARO, Christiane; DINIZ, Marcio Augusto; MORAES-FILHO, Joaquim Prado; FASS, Ronnie; BARBUTI, Ricardo CorreaAim. To compare 10-day standard triple therapy versus sequential therapy as first-line treatment in patients infected with H. pylori. Methods. One hundred H. pylori positive patients (diagnosed by rapid urease test and histology), with average age of 47.2, M/F = 28/72, were randomized to receive either standard triple treatment (TT) as follows: lansoprazole 30 mg, clarithromycin 500 mg, and amoxicillin 1 g, b.i.d. for ten days, or sequential treatment (ST) as follows: lansoprazole 30 mg, amoxicillin and placebo 1.0 g b.i.d for the first five days, followed by lansoprazole 30 mg, clarithromycin 500 mg, and tinidazole 500 mg b.i.d, for the remaining five days. Eradication rates were determined 60 days after treatment by urease, histology, or C-13-urea breath test. Results. In intention to treat (ITT) analysis, the rate of H. pylori eradication in the TT and ST groups was the same for both regimens as follows: 86% (43/50), 95% CI 93,3 to 73.4%. In Per protocol (PP) analysis, the rate of H. pylori eradication in the TT and ST groups was 87.8% (43/49), 95% CI 94,5 to 75.3% and 89.6% (43/48), 95% CI 95,8 to 77.3%, respectively. Conclusions. In Brazil, standard triple therapy is as equally effective as sequential therapy in eradicating Helicobacter pylori patients. This study was registered under Clinical Trials with number ISRCTN62400496.
- Temporal Association Between Respiratory Events and Reflux in Patients With Obstructive Sleep Apnea and Laryngopharyngeal Reflux(2019) XAVIER, Sandra Doria; ECKLEY, Claudia Alessandra; DUPRAT, Andre Campos; FONTES, Luiz Henrique de Souza; NAVARRO-RODRIGUEZ, Tomas; PATROCINIO, Julio; TRIDENTE, Daniela; LORENZI-FILHO, GeraldoStudy Objectives: The aim of the current study was to test the hypothesis that there is a temporal correlation between reflux episodes and respiratory events in patients with laryngopharyngeal reflux and obstructive sleep apnea. Methods: Adults with clinically diagnosed laryngopharyngeal reflux confirmed by two validated instruments (reflux symptom index >= 13 and reflux finding score >= 7) and obstructive sleep apnea (OSA) underwent full polysomnography with concomitant and synchronized multichannel intraluminal impedance-pH esophageal monitoring. The apnea-hypopnea and arousal indexes that occurred 15, 30, and 45 minutes before and after each reflux episode were recorded and compared to full-night apnea and hypopnea and arousal index. Results: We studied 27 patients (14 males, age 51.7 +/- 9.1 years, body mass index 32.4 +/- 4.2 kg/m(2)) with laryngopharyngeal reflux (reflux symptom index 16 +/- 2 and reflux finding score 12 +/- 3) and OSA (apnea-hypopnea index = 32.3 +/- 28.4 events/h). We evaluated 102 reflux episodes. Almost half of the reflux episodes occurred while awake (43.1%) and only five reflux episodes (4.9%) occurred during an obstructive respiratory event. The apnea and hypopnea and arousal indexes 15, 30, and 45 minutes before and after reflux episodes were lower than full-night apnea and hypopnea and arousal indexes, respectively. Conclusions: Among patients with well-established laryngopharyngeal reflux and OSA, there is no temporal association between reflux and obstructive respiratory events. Even though the data comprised a small sample size, it seems that a more complex mechanism is involved with these two highly prevalent diseases.
