RESUMO

BACKGROUND: Gastric ulcers represent a worldwide health problem, characterized by erosions that affect the mucous membrane of the stomach and may even reach the muscular layer, leading to serious complications. Numerous natural products have been assessed as anti-ulcerogenic agents, and have been considered as new approaches for treatment or prevention of gastric ulcers. The present research investigated the preventive benefits of Apium graveolens L. (Apiaceae), known as celery, seed extract towards indomethacin-induced ulceration of the stomach in rats. METHODS: Metabolomic profiling, employing liquid chromatography coupled to high-resolution electrospray ionization mass spectrometry (LC-HR-ESI-MS), was implemented with the aim of investigating the chemical profile of the seeds. Histopathological analysis of gastric tissues, as well as assessment of numerous inflammatory cytokines and oxidative stress indicators, confirmed the in vivo evaluation. RESULTS: The prior treatment with A. graveolens seed extract resulted in a substantial reduction in the ulcer index when compared to the indomethacin group, indicating an improvement in stomach mucosal injury. Moreover, the gastroprotective effect was demonstrated through examination of the oxidative stress biomarkers which was significantly attenuated upon pre-treatment with A. graveolens seed extract. Vascular endothelial growth factor (VEGF), a fundamental angiogenic factor that stimulates angiogenesis, was markedly inhibited by indomethacin. A. graveolens seed extract restored this diminished level of VEGF. The dramatic reductions in NF-κB protein levels indicate a considerable attenuation of the indomethacin-induced IKκB/NF-κB p65 signaling cascade. These activities were also correlated to the tentatively featured secondary metabolites including, phenolic acids, coumarins and flavonoids, previously evidenced to exert potent anti-inflammatory and antioxidant activities. According to our network pharmacology study, the identified metabolites annotated 379 unique genes, among which only 17 genes were related to gastric ulcer. The PTGS2, MMP2 and PTGS1 were the top annotated genes related to gastric ulcer. The top biological pathway was the VEGF signaling pathway. CONCLUSION: A. graveolens seed extract possesses significant anti-ulcer activity, similar to famotidine, against gastric lesions induced by indomethacin in rats. It is worth highlighting that the extract overcomes the negative effects of conventional chemical anti-secretory drugs because it does not lower stomach acidity.

RESUMO

OBJECTIVE: To estimate the incidence rates (IR) of prespecified outcomes of interest in pediatric patients (1 month to < 1 year) treated with intravenous (IV) pantoprazole using Optum's longitudinal electronic health records database (Optum Market Clarity) from the United States (US). METHODS: This real-world, non-interventional, retrospective cohort study was conducted from 01 January 2007 to 31 December 2020 in patients who received IV pantoprazole. Premature patients and those weighing < 2.36 kg were excluded. Patients were categorized based on diagnosis of gastroesophageal reflux disease (GERD) and erosive esophagitis (EE) into: Subgroup 1 (GERD and EE), Subgroup 2 (GERD and no EE), and Subgroup 3 (absence of GERD and EE). Overall IRs (per 1000 person-years [PY]) and 95% confidence intervals (CI) of outcomes were estimated (overall and subgroups) and stratified by duration of IV pantoprazole treatment (< 4 days versus ≥ 4 days). RESULTS: Of 1879 eligible patients, none were identified in Subgroup 1; 851 (45.3%) and 1028 (54.7%) patients were identified in Subgroups 2 and 3, respectively. IRs of outcomes of interest ranged from 0.0 to 742.8 per 1000 PY. IRs were highest for vomiting (742.80), diarrhea (377.77), abdominal distension (214.31), hyponatremia (204.99), and hypokalemia (203.49). IRs were comparable between Subgroups 2 and 3. For most outcomes, IRs were higher among patients treated with IV pantoprazole for ≥ 4 days versus those treated for < 4 days. CONCLUSION: These results are consistent with the known safety profile of pantoprazole and emphasize the utility of using real-world data from pediatric populations for assessment of safety outcomes.

RESUMO

BACKGROUND: Gastric and duodenal ulcerations are common during multiple-dosing aspirin treatment, such as for prevention of cardiovascular disease. On capsule endoscopy, oral administration of the bacterial strain Bifidobacterium breve Bif195 (DSM 33360) reduced the risk of aspirin-induced small intestinal damage, without affecting cyclo-oxygenase-2 (COX-2) inhibition. AIM: To evaluate endoscopically the effect of Bif195 on aspirin-induced stomach and duodenal mucosal damage METHODS: Twenty-five healthy volunteers underwent two intervention periods in a randomised, double-blind, placebo-controlled crossover design including four gastroduodenoscopies and 6 weeks washout. Each intervention was a 4-week oral co-treatment of aspirin 300 mg daily and Bif195 (≥1011 colony-forming units daily) or placebo. Primary endpoint was change in Lanza score - ranging from 0 (normal mucosa) to 4 (>10 erosions or ulcer). RESULTS: All 25 participants (56% females); age 27.3 (±4.8) years; BMI 23.2 (±3.4) kg/m2 , completed the trial exhibiting significant increases in Lanza scores during placebo treatment as compared to baseline. Bif195 reduced gastric Lanza score with an odds ratio of 7.2 (95% confidence interval 1.72-30.08, p = 0.009) compared to placebo with no related adverse events. There were no significant changes in Lanza scores in the duodenum. CONCLUSIONS: Bif195 reduces aspirin-induced gastric mucosal damage and may serve as a safe supplement during multiple-dosing aspirin treatment.

RESUMO

Gastric ulcer is a common gastrointestinal disease caused by excessive gastric acid secretion, which has been recognized as one of the most common causes of morbidity and mortality in the world. The skin of Rana chensinensis is rich in collagen and many previous studies have shown that it has certain bioactivity. Therefore, we extracted and purified collagen with a molecular weight less than 10000 Da from the skin of Rana chensinensis, and studied its gastric protective mechanism through the model of ethanol-induced gastric ulcer in Balb/c mice. The results showed that through macroscopic observation and significantly reduced ulcer index, it was proved that PCRCS could protect gastric mucosa and alleviate the damage of ethanol to gastric mucosa. PCRCS reduced ethanol-induced oxidative stress by boosting depleted SOD levels and dramatically lowering MDA levels, as well as significantly reducing lipid peroxidation. Additionally PCRCS (Protein Chinese Rana chesinensis Skin) additionally decreased the launch of inflammatory mediators TNF-α and IL-6 and more desirable the content material of protective elements NO and PGE2 in gastric mucosa. Based on these findings, we believe that PCRCS has potential stomach protective effects on ethanol-induced gastric ulcer, which may be achieved by inhibiting oxidative stress and stomach inflammation.

RESUMO

INTRODUCTION: Keverprazan is a novel potassium-competitive acid blocker for the treatment of acid-related disorders requiring potent acid inhibition. This study aimed to establish the noninferiority of keverprazan to lansoprazole in the treatment of patients with duodenal ulcer (DU). METHODS: In this phase III, double-blind, multicenter study, 360 Chinese patients with endoscopically confirmed active DU were randomized 1:1 to take either keverprazan (20 mg) or lansoprazole (30 mg) treatment for up to 6 weeks. The primary end point was DU healing rate at week 6. The secondary end point was DU healing rate at week 4. Symptom improvement and safety were also assessed. RESULTS: Based on the full analysis set, the cumulative healing rates at week 6 were 94.4% (170/180) and 93.3% (166/178) for keverprazan and lansoprazole, respectively (difference: 1.2%; 95% confidence intervel: -4.0%-6.5%). At week 4, the respective healing rates were 83.9% (151/180) and 80.3% (143/178). In the per protocol set, the 6-week healing rates in keverprazan and lansoprazole groups were 98.2% (163/166) and 97.6% (163/167), respectively (difference: 0.6%; 95% confidence intervel: -3.1%-4.4%); the 4-week healing rates were respectively 86.8% (144/166) and 85.6% (143/167). Keverprazan was noninferior to lansoprazole in DU healing after the treatment for 4 and 6 weeks. The incidence of treatment-emergent adverse events was comparable among groups. DISCUSSION: Keverprazan 20 mg had a good safety profile and was noninferior to lansoprazole 30 mg once daily for DU healing.

RESUMO

Objective To evaluate the efficacy and safety of rabeprazole coadministration with low-dose aspirin (LDA). Methods From 2015 to 2018, we conducted a large-scale, multicenter, prospective observational study to assess the safety and efficacy of treatment with rabeprazole (5 or 10 mg/day) in combination with LDA. Results The incidence of adverse reactions was 0.73% (11/1,513 patients), with no serious adverse reactions. We found no trend toward increases in the incidence of adverse reactions with increases in treatment duration. The cumulative recurrence rate of ulcers by Week 52 (Kaplan-Meier estimates) was 3.50% (range, 1.56-7.75%). No gastrointestinal bleeding was reported. Conclusion Rabeprazole in combination with LDA appears as safe and effective in real-world situations as in clinical trials.

RESUMO

Background: The analgesic drugs are the main cause of gastric ulcer. The objective of this study was to determine the gastroprotective ability of flavonoid, 6-aminoflavone in a rat pyloric ligation model of aspirin associated gastro-ulcerogenesis. Methods: A laboratory based experimental study was conducted in the animal house and research laboratory at Khyber Medical College, Peshawar from July to November 2019. A total of 42 adult male Spargue-Dawely rats were divided into seven groups. Flavonoid, 6-aminoflavone was administered orally in doses of 10, 25 and 100 mg/kg with misoprostol, as standard at 50 µg/kg orally for 4 days. On the last day aspirin was given orally at 200 mg/kg and the pyloric ligation surgery was performed. After 4 hours all animals were killed by cervical dislocation. The gastric tissues were collected for histomorphological study. The obtained data were expressed as mean±SEM. Analysis was carried out by using ANOVA. p value ˂0.05 was considered significant. Results: The animals treated with the different doses of 6-aminoflavone showed a marked protective effect in the histological observations. The 10 mg/kg dose had a mild protective effect as occasional ulcerative changes were observed. However, doses of 25 and 100 mg/kg significantly caused the reduction in the ulcer score. These effects produced were equipotent to the gastroprotective effectiveness inherent in the misoprostol. . Conclusion: These findings conclude that 6-aminoflavone as like other flavonoids has a significant gastroprotective propensity with significant effect produced at doses of 25 and 100 mg/kg and can be used as a part of therapy management for the treatment of gastrointestinal disease particularly ulcerative condition.

RESUMO

Importance: In arthroscopic knee and shoulder surgery, there is growing evidence that opioid-sparing protocols may reduce postoperative opioid consumption while adequately addressing patients' pain. However, there are a lack of prospective, comparative trials evaluating their effectiveness. Objective: To evaluate the effect of a multimodal, opioid-sparing approach to postoperative pain management compared with the current standard of care in patients undergoing arthroscopic shoulder or knee surgery. Design, Setting, and Participants: This randomized clinical trial was performed at 3 clinical sites in Ontario, Canada, and enrolled 200 patients from March 2021 to March 2022 with final follow-up completed in April 2022. Adult patients undergoing outpatient arthroscopic shoulder or knee surgery were followed up for 6 weeks postoperatively. Interventions: The opioid-sparing group (100 participants randomized) received a prescription of naproxen, acetaminophen (paracetamol), and pantoprazole; a limited rescue prescription of hydromorphone; and a patient educational infographic. The control group (100 participants randomized) received the current standard of care determined by the treating surgeon, which consisted of an opioid analgesic. Main Outcomes and Measures: The primary outcome was postoperative oral morphine equivalent (OME) consumption at 6 weeks after surgery. There were 5 secondary outcomes, including pain, patient satisfaction, opioid refills, quantity of OMEs prescribed at the time of hospital discharge, and adverse events at 6 weeks all reported at 6 weeks after surgery. Results: Among the 200 patients who were randomized (mean age, 43 years; 73 women [38%]), 193 patients (97%) completed the trial; 98 of whom were randomized to receive standard care and 95 the opioid-sparing protocol. Patients in the opioid-sparing protocol consumed significantly fewer opioids (median, 0 mg; IQR, 0-8.0 mg) than patients in the control group (median, 40.0 mg; IQR, 7.5-105.0; z = -6.55; P < .001). Of the 5 prespecified secondary end points, 4 showed no significant difference. The mean amount of OMEs prescribed was 341.2 mg (95% CI, 310.2-372.2) in the standard care group and 40.4 mg (95% CI, 39.6-41.2) in the opioid-sparing group (mean difference, 300.8 mg; 95% CI, 269.4-332.3; P < .001). There was no significant difference in adverse events at 6 weeks (2 events [2.1%] in the standard care group vs 3 events [3.2%] in the opioid-sparing group), but more patients reported medication-related adverse effects in the standard care group (32% vs 19%, P = .048). Conclusions and Relevance: Among patients who underwent arthroscopic knee or shoulder surgery, a multimodal opioid-sparing postoperative pain management protocol, compared with standard opioid prescribing, significantly reduced postoperative opioid consumption over 6 weeks. Trial Registration: ClinicalTrials.gov Identifier: NCT04566250.

RESUMO

Silver nanoparticles (Ag NPs) have unique properties and display an important role in bioactivities such as antimicrobial, antiviral, antifungal, and anticancer. Stable Ag NPs were prepared by reaction of silver nitrate solution with extract of Melissa and characterized by UV-Vis spectroscopy, AFM, SEM, XRD, and Zeta potential. The resulted Ag NPs have a size range between 20 and 35 nm. The current study aims to evaluate the gastroprotective effect of Ag NPs against ethanol-induced gastric ulcers in rats. Thirty rats were randomly divided into five groups. The experimental groups were fed 175 and 350 ppm/p.o of Ag NPs orally. Ag NPs improved the adversative influence of ethanol-induced stomach damage as confirmed by declining ulcer index and raised the percentage of ulcer prevention. Significantly reduced ethanol-induced gastric lesions were evidenced by increased mucus secretion and pH of stomach content, decreased ulcer area, nonappearance of edema, and leucocyte penetration of the subcutaneous layer. In gastric homogenate, Ag NPs displayed a substantial upsurge in superoxide dismutase (SOD), catalase (CAT) activities, and significantly reduced malondialdehyde (MDA) levels., Ag NPs increased the intensity of periodic acid Schiff stained (PAS) and produced over-regulation of HSP-70 and down-regulation of Bax proteins. Ag NPs confirmed gastro-protection which might be attributed to its antioxidant effect, increased mucus secretion, increased SOD, and CAT, reduced MDA level, over-regulation of HSP-70 protein, and down-regulation of Bax protein.

RESUMO

OBJECTIVE: Management of erosive oesophagitis (EE) remains suboptimal, with many patients experiencing incomplete healing, ongoing symptoms, and relapse despite proton pump inhibitor (PPI) treatment. The Study of Acid-Related Disorders investigated patient burden of individuals with EE in a real-world setting. DESIGN: US gastroenterologists (GIs) or family physicians (FPs)/general practitioners (GPs) treating patients with EE completed a physician survey and enrolled up to four patients with EE for a patient survey, with prespecified data extracted from medical records. RESULTS: 102 GIs and 149 FPs/GPs completed the survey; data were available for 73 patients (mean age at diagnosis, 45.4 years). Omeprazole was healthcare professional (HCP)-preferred first-line treatment (60.8% GIs; 56.4% FPs/GPs), and pantoprazole preferred second line (29.4% and 32.9%, respectively). Price and insurance coverage (both 55.5% HCPs) and familiarity (47.9%) key drivers for omeprazole; insurance coverage (52.0%), price (50.0%), familiarity (48.0%), initial symptom relief (46.0%), and safety (44.0%) key drivers for pantoprazole. Only 49.3% patients took medication as instructed all the time; 56.8% independently increased medication frequency some of the time. Despite treatment, 57.5% patients experienced heartburn and 30.1% regurgitation; heartburn was the most bothersome symptom. 58.9% patients believed that their symptoms could be better controlled; only 28.3% HCPs were very satisfied with current treatment options. 83.6% patients wanted long-lasting treatment options. Fast symptom relief for patients was a top priority for 66.1% HCPs, while 56.6% would welcome alternatives to PPIs. CONCLUSION: This real-world multicentre study highlights the need for new, rapidly acting treatments in EE that reduce symptom burden, offer durable healing and provide symptom control.

RESUMO

BACKGROUND AND AIM: Duodenal ulcers, especially caused by increasingly drug-resistant Helicobacter pylori, are a concern in Asia. We compared oral vonoprazan versus lansoprazole for efficacy (healing duodenal ulcers) and safety in non-Japanese Asian patients. METHODS: In this phase 3, randomized (1:1), double-blind, double-dummy, parallel-group, non-inferiority study (April 5, 2017, to July 19, 2019), patients with ≥ 1 endoscopically confirmed duodenal ulcer, at 52 hospitals (China, South Korea, and Taiwan), received vonoprazan 20 mg once daily (QD) or lansoprazole 30 mg QD for 6 weeks maximum. Patients with H. pylori received bismuth-containing quadruple therapy including vonoprazan 20 mg twice daily (BID) or lansoprazole 30 mg BID, for 2 weeks, followed by vonoprazan or lansoprazole monotherapy QD (4 weeks maximum). Endpoints were endoscopically confirmed duodenal ulcer healing (Week 4/6; primary) and H. pylori eradication (4 weeks post-treatment; secondary); non-inferiority margins were -6% and -10%, using a two-sided 95% confidence interval (CI). RESULTS: Of 533 enrolled patients, one was lost to follow-up and one withdrew (full analysis set: 531 patients [vonoprazan, n = 263; lansoprazole, n = 268]; 85.4% = H. pylori positive). Vonoprazan was non-inferior to lansoprazole for duodenal ulcer healing (96.9% vs 96.5%; difference 0.4% [95% CI -3.00, 3.79]). H. pylori eradication rates were 91.5% (vonoprazan) and 86.8% (lansoprazole; difference 4.7% [95% CI -1.28, 10.69]). Vonoprazan and lansoprazole were well tolerated, with similar safety profiles, no new safety signals; no deaths occurred. CONCLUSIONS: Vonoprazan was well tolerated and non-inferior to lansoprazole for duodenal ulcer healing and achieved H. pylori eradication above the clinically meaningful threshold (90%), in non-Japanese Asian patients.

RESUMO

Aegle marmelos is cost-effective valuable South Asian tree. The folklore data reported its wide range pharmacological effects. In spite of vast reported work on various parts, the dry ripe fruit extract has not yet been studied for gastric ulcers. Present study is planned to investigate its potential protective effects against ethanol-induced gastric injury in rats. In current study the gastro protective effect of ethanolic crude extract of A. marmelos dried ripe fruit at 200, 400 and 800mg/kg body weight were studied in albino rats. Ranitidine used as standard drug (50mg/kg body weight). Absolute ethanol increase the degree of ulceration (UI) in rats while a significant improvement in the level of inhibition against ulceration was observed in test and standard groups as compare to control. Pre-fed test drug exhibited a significant reduction in the sore area (UI), accelerate % age protection and increased of gastric content in dose dependence manner. Test drug at 800mg/kg dose showed marked deduction in mean UI 3.0, significant increase in protection 83% with pH 7.3 (p<0.01). Standard drug exhibited 3.25 UI, 81% protection with pH 7.1. In conclusion, it was found that dry ripe fruit of A. marmelos possesses a significant anti-ulcer effect in rats.

RESUMO

Paspalidium flavidum (watercrown grass), a medicinal plant, is traditionally used in liver ailments and stomach problems. The hepatoprotective and gastroprotective activities of the aqueous methanol extract of Paspalidium flavidum (AMEPF) were studied in experimental animal models. Paracetamol and aspirin were used to induce hepatotoxicity and gastric ulcer in rats, respectively. Biochemical hepatic parameters, gastric pH, total acidity, ulcer index, percentage protection, nitric oxide and TNF-α were measured in AMEPF-treated groups. Moreover, GC-MS analysis of AMEPF was performed. Pretreatment with AMEPF improved the blood lipid profile and restored liver function tests in paracetamol-induced hepatotoxicity. While in aspirin-induced gastric ulcer, oral administration of AMEPF significantly reduced (P<0.05) the gastric lesions, total acidity and ulcer scoring index, TNF-α with upregulation of nitric oxide when compared with the Diseased group. AMEPF exhibited anti-lipid peroxidation activity. Histopathological studies were in good agreement with the biochemical findings. GC-MS analysis revealed the presence of anti-oxidant phyto-constituents, including oleic acid and 1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) in AMEPF.

RESUMO

Peptic ulcer is a widespread disease, with a lifetime frequency of 5−10% among the general population and an annual incidence of 0.1−0.3%. Ovothiol A is naturally produced from sea urchin eggs with special antioxidant activity. Gastric ulcers were induced in rats by a single ethanol dose (5 mL/kg). The rats were divided into control, ulcer, and ulcer with 250 and 500 mg/kg ovothiol A doses. Molecular docking studies were used to examine the interactions between ovothiol A and the H+/K+ ATPase active site residues. Ovothiol A led to a significant decline (p < 0.05) in gastric juice volume, ulcer index, MDA, IL-6, and cytochrome c, while levels of gastric juice pH, GSH, CAT, GST, SOD, and NO increased. Histopathological investigation of stomach sections revealed architecture preservation of the gastric mucosa after ovothiol A administration. The anti-ulcerogenic activity of ovothiol A includes scavenging free radicals, inhibition of inflammation, regulation of apoptosis, and stabilization of fibroblast growth factors to promote gastric ulcers healing.

RESUMO

Proton pump inhibitors (PPIs), followed by histamine 2 receptor antagonists (H2RAs), are the most commonly used drugs to prevent gastrointestinal bleeding in critically ill patients through stress ulcer prophylaxis. The relative efficacy and drug-related adverse events of PPIs and H2RAs remain unclear. In this retrospective, observational, comparative cohort study, PPIs and H2RAs for stress ulcer prophylaxis in critically ill patients were compared using a common data model. After propensity matching, 935 patients from each treatment group (PPI or H2RA) were selected. The PPI group had a significantly higher 90-day mortality than the H2RA group (relative risk: 1.28; P = 0.01). However, no significant inter-group differences in the risk of clinically important gastrointestinal bleeding were observed. Moreover, there were no significant differences between the groups concerning the risk of pneumonia or Clostridioides difficile infection, which are known potential adverse events related to these drugs. Subgroup analysis of patients with high disease severity were consistent with those of the total propensity score-matched population. These findings do not support the current recommendations, which prefer PPIs for gastrointestinal bleeding prophylaxis in the intensive care unit.

RESUMO

OBJECTIVES: The World Health Organization (WHO) estimated that more than 50% of drugs were prescribed incorrectly, including stress ulcer prophylaxis (SUP) drugs. Prescribing SUP drugs in incorrect doses and frequencies are considered irrational, and may affects to the effectivity of the therapy. This research aimed to assess the appropriateness of the SUP drugs regimentation in the inpatient surgery room at Dr. Soetomo Hospital, Surabaya, Indonesia. METHODS: This research was cross-sectional study and conducted for 4 weeks in 2019 in the inpatient surgery room of Dr. Soetomo Hospital. The population was SUP drugs that were prescribed in inpatient surgery room. Those SUP drugs with indications for the prevention of stress-induced ulcers that complied to the terms listed on the American Society of Health-System Pharmacists (ASHP) were included as the samples, and vice versa. The samples then assessed for their regimentation appropriateness using the dose and frequency standard of ASHP. RESULTS: There were 224 dose units taken as sample, from the total population of 1,404 SUP drugs. The result showed that as much as 48.2% of SUP medications were given to the patients in inappropriate regimentation. Of that number, all ranitidine injection were inappropriately regimented. On the contrary all omeprazole injection dose units were appropriately regimented, meanwhile the amount of appropriate regimentation of sucralfate suspension were 74.6%. CONCLUSIONS: According to ASHP standard, the SUP drugs in the inpatient surgery room at Dr. Soetomo Hospital were mostly given in inappropriate regimentation. Further research is needed to explore how will those inappropriate regimentation affect on the efficacy of therapy in the patients.

RESUMO

OBJECTIVE: To determine whether the use of acid suppression and thickened feeds impact laryngomalacia outcomes in infants, including supraglottoplasty risk, time to supraglottoplasty, and hospitalization risk. STUDY DESIGN: We performed a retrospective cohort study to compare risk and time with supraglottoplasty and frequency and duration of hospitalizations for infants diagnosed with laryngomalacia at Boston Children's Hospital between January 1 and December 31, 2017. The primary outcomes were supraglottoplasty requirement, time to supraglottoplasty, and hospitalization risk. Multivariate analyses were performed to determine predictors of supraglottoplasty and hospitalization risk after adjusting for laryngomalacia severity and comorbidities in addition to propensity score adjustment. Kaplan-Meier curves were created to determine the impact of acid suppression use on time to supraglottoplasty. RESULTS: In total, 236 subjects with mean age 62.6 ± 4 days were included in the analysis; 55% were treated with acid suppression. Subjects treated with acid suppression had a greater risk of supraglottoplasty (hazard ratio 3.36, 95% CI 1.36-8.29, P = .009), shorter time to supraglottoplasty (5.64 ± 0.92 vs 7.98 ± 1.92 months, P = .006), and increased respiratory hospitalization risk (relative risk 1.97, 95% CI 1.01-3.85, 0.047), even after adjustment for covariates. Subjects receiving thickening had fewer respiratory hospitalization nights and longer time to supraglottoplasty (9.3 ± 1.7 vs 4.56 ± 0.73 months, P = .004), even after adjustment. CONCLUSIONS: Acid suppression use does not reduce the frequency of supraglottoplasty and related hospitalizations compared with untreated subjects. However, patients treated with thickening have decreased hospitalization and longer time to supraglottoplasty, suggesting that thickening of feeds may be a preferred intervention over acid suppression.
