Outcomes and Factors Associated With Reduced Symptoms in Patients With Gastroparesis.

ABSTRACT: Gastroparesis is a chronic clinical syndrome characterized by delayed gastric emptying. However, little is known about patient outcomes or factors associated with reduction of symptoms.We studied adult patients with gastroparesis (of diabetic or idiopathic type) enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases Gastroparesis Clinical Research Consortium Gastroparesis Registry, seen every 16 weeks and treated according to the standard of care with prescribed medications or other therapies at 7 tertiary care centers. Characteristics associated with reduced symptoms, based on a decrease of 1 or more in the gastroparesis cardinal symptom index (GCSI) score after 48 weeks of care, were determined from logistic regression models. Data were collected from patients for up to 4 years (median, 2.1 y).Of 262 patients, 28% had reductions in GCSI scores of 1 or more at 48 weeks. However, there were no significant reductions in GCSI score from weeks 48 through 192. Factors independently associated with reduced symptoms at 48 weeks included male sex, age 50 years and older, initial infectious prodrome, antidepressant use, and 4-hour gastric retention greater than 20%. Factors associated with no reduction in symptoms included overweight or obesity, a history of smoking, use of pain modulators, moderate to severe abdominal pain, a severe gastroesophageal reflex, and moderate to severe depression.Over a median follow-up period of 2.1 years, 28% of patients treated for gastroparesis at centers of expertise had reductions in GCSI scores of 1 or greater, regardless of diabetes. These findings indicate the chronic nature of gastroparesis. We identified factors associated with reduced symptoms that might be used to guide treatment. ClinicalTrials.gov no: NCT00398801.

Project description:Background & aimsGastroparesis is a chronic disorder of the stomach characterized by nausea, vomiting, early satiety, postprandial fullness, and abdominal pain. There is limited information on gastroparesis in minority populations. We assessed ethnic, racial, and sex variations in the etiology, symptoms, quality of life, gastric emptying, treatments, and symptom outcomes of patients with gastroparesis.MethodsWe collected information from the National Institutes of Health Gastroparesis Consortium on 718 adult patients, from September 2007 through December 2017. Patients were followed every 4 or 6 months, when data were collected on medical histories, symptoms (based on answers to the PAGI-SYM questionnaires), and quality of life (based on SF-36). Follow-up information collected at 1 year (48 week) was used in this analysis. Comparisons were made between patients of self-reported non-Hispanic white, non-Hispanic black, and Hispanic ethnicities, as well as and between male and female patients.ResultsOur final analysis included 552 non-Hispanic whites (77%), 83 persons of Hispanic ethnicity (12%), 62 non-Hispanic blacks (9%), 603 women (84%), and 115 men (16%). A significantly higher proportion of non-Hispanic blacks (60%) had gastroparesis of diabetic etiology than of non-Hispanic whites (28%); non-Hispanic blacks also had more severe retching (2.5 vs 1.7 score) and vomiting (2.9 vs 1.8 score) and a higher percentage were hospitalized in the past year (66% vs 38%). A significantly higher proportion of Hispanics had gastroparesis of diabetic etiology (59%) than non-Hispanic whites (28%), but Hispanics had less-severe nausea (2.7 vs 3.3 score), less early satiety (3.0 vs 3.5 score), and a lower proportion used domperidone (8% vs 21%) or had a peripherally inserted central catheter (1% vs 7%). A higher proportion of women had gastroparesis of idiopathic etiology (69%) than men (46%); women had more severe symptoms of stomach fullness (3.6 vs 3.1 score), early satiety (3.5 vs 2.9 score), postprandial fullness (3.7 vs 3.1 score), bloating (3.3 vs 2.6 score), stomach visibly larger (3.0 vs 2.1 score), and upper abdominal pain (2.9 vs 2.4 score). A lower proportion of women were hospitalized in past year (39% vs 53% of men).ConclusionsIn patients with gastroparesis, etiologies, symptom severity, and treatments vary among races and ethnicities and between sexes.

Project description:Background & aimsThe use of domperidone (DOM) for gastroparesis (GP) remains controversial and limited. We aimed to present outcomes of DOM therapy for treatment of patients participating in the multicenter National Institute of Diabetes and Digestive and Kidney Diseases Gastroparesis Clinical Research Consortium (GpCRC) Registries (GpR).MethodsThe GpCRC cohort consisted of patients with GP (75%) and with GP-like symptoms but with normal gastric emptying (25%). The DOM group initiated therapy during the 96 weeks of enrollment in GpR1 and GpR2. Patients who had previously taken or who were on DOM therapy at enrollment were excluded from this analysis. The control group did not use domperidone (non-DOM group) before or after enrollment. The following outcome measures were identified: change from baseline in Gastroparesis Cardinal Symptom Index total score, with 3 subscales, plus Gastroesophageal Reflux Disease and Patient Assessment of Upper Gastrointestinal Disorders-Quality of Life scores.ResultsOverall, of 748 patients, 181 (24%) were in the DOM group, whereas 567 were in the non-DOM group. Sixty-three percent of participants had idiopathic GP. At baseline, DOM patients compared with non-DOM patients were significantly younger, had lower body mass index, non-Hispanic ethnicity, a higher annual household income, lower narcotic utilization, lower supplemental and complimentary medication use, and were more likely to have delayed gastric emptying time, as well as worse nausea and fullness scores. Compared with non-DOM patients, DOM patients experienced moderate but significantly more improvement in GP outcome measures: Gastroparesis Cardinal Symptom Index total score (P = .003), nausea (P = .003), and fullness subscales (P =.005), upper abdominal pain score (P = .04), Gastroesophageal Reflux Disease score (P = .05), and Patient Assessment of Upper Gastrointestinal Disorders-Quality of Life score (P = .05).ConclusionsUtilizing the method of pragmatic modeling to evaluate long-term treatment of GP in a large GpCRC database, DOM treatment resulted in moderately but significantly improved GP. NOTE: This project was based on data generated by 2 GpCRC Registry studies recognized under the Clinicaltrial.gov numbers: NCT00398801 and NCT01696747 symptoms compared with a group receiving standard-of-care but not DOM.

Project description:Background & aimsThere are few effective treatments for nausea and other symptoms in patients with gastroparesis and related syndromes. We performed a randomized trial of the ability of the neurokinin-1 receptor antagonist aprepitant to reduce symptoms in patients with chronic nausea and vomiting caused by gastroparesis or gastroparesis-like syndrome.MethodsWe conducted a 4-week multicenter, double-masked trial of 126 patients with at least moderate symptoms of chronic nausea and vomiting of presumed gastric origin for a minimum of 6 months. Patients were randomly assigned to groups given oral aprepitant (125 mg/day, n = 63) or placebo (n = 63). The primary outcome from the intention-to-treat analysis was reduction in nausea, defined as a decrease of 25 mm or more, or absolute level below 25 mm, on a daily patient-reported 0-to-100 visual analog scale (VAS) of nausea severity. We calculated relative risks of nausea improvement using stratified Cochran-Mental-Haenszel analysis.ResultsAprepitant did not reduce symptoms of nausea, based on the primary outcome measure (46% reduction in the VAS score in the aprepitant group vs 40% reduction in the placebo group; relative risk, 1.2; 95% CI, 0.8-1.7) (P = .43). However, patients in the aprepitant group had significant changes in secondary outcomes such as reduction in symptom severity (measured by the 0-5 Gastroparesis Clinical Symptom Index) for nausea (1.8 vs 1.0; P = .005), vomiting (1.6 vs 0.5; P = .001), and overall symptoms (1.3 vs 0.7; P = .001). Adverse events, predominantly mild or moderate in severity grade, were more common in aprepitant (22 of 63 patients, 35% vs 11 of 63, 17% in the placebo group) (P = .04).ConclusionsIn a randomized trial of patients with chronic nausea and vomiting caused by gastroparesis or gastroparesis-like syndrome, aprepitant did not reduce the severity of nausea when reduction in VAS score was used as the primary outcome. However, aprepitant had varying effects on secondary outcomes of symptom improvement. These findings support the need to identify appropriate patient outcomes for trials of therapies for gastroparesis, including potential additional trials for aprepitant.
