Polyethylene Glycol 3350 With Electrolytes Versus Polyethylene Glycol 4000 for Constipation: A Randomized, Controlled Trial.

ABSTRACT: OBJECTIVE:The long-term efficacy and safety of polyethylene glycol (PEG) in constipated children are unknown, and a head-to-head comparison of the different PEG formulations is lacking. We aimed to investigate noninferiority of PEG3350 with electrolytes (PEG3350?+?E) compared to PEG4000 without electrolytes (PEG4000). METHODS:In this double-blind trial, children aged 0.5 to 16 years with constipation, defined as a defecation frequency of <3 times per week, were randomized to receive either PEG3350?+?E or PEG4000. Primary outcomes were change in total sum score (TSS) at week 52 compared to baseline, and dose range determination. TSS was the sum of the severity of 5 constipation symptoms rated on a 4-point scale (0-3). Noninferiority margin was a difference in TSS of ?1.5 based on a 95%-confidence interval [CI]. Treatment success was defined as a defecation frequency of ?3 per week with <1 episode of fecal incontinence. RESULTS:Ninety-seven subjects were included, of whom 82 completed the study. Mean reduction in TSS was -3.81 (95% CI: -4.96 to -2.65) and -3.74 (95%CI: -5.08 to -2.40), for PEG3350?+?E and PEG4000, respectively. Noninferiority criteria were not met (maximum difference between groups: -1.81 to 1.68). Daily sachet use was: 0 to 2 years: 0.4 to 2.3 and 0.9 to 2.1; 2 to 4 years: 0.1 to 3.5 and 1.2 to 3.2; 4 to 8 years: 1.1 to 2.8 and 0.7 to 3.8; 8 to 16 years 0.6 to 3.7 and 1.0 to 3.7, in PEG3350?+?E and PEG4000, respectively. Treatment success after 52 weeks was achieved in 50% and 45% of children, respectively (P?=?0.69). Rates of adverse events were similar between groups, and no drug-related serious adverse events occurred. CONCLUSIONS:Noninferiority regarding long-term constipation-related symptoms of PEG3350?+?E compared to PEG4000 was not demonstrated. However, analysis of secondary outcomes suggests similar efficacy and safety of these agents.

<h4>Objective</h4>The long-term efficacy and safety of polyethylene glycol (PEG) in constipated children are unknown, and a head-to-head comparison of the different PEG formulations is lacking. We aimed to investigate noninferiority of PEG3350 with electrolytes (PEG3350 + E) compared to PEG4000 without electrolytes (PEG4000).<h4>Methods</h4>In this double-blind trial, children aged 0.5 to 16 years with constipation, defined as a defecation frequency of <3 times per week, were randomized to recei ...[more]

Project description:IMPORTANCE:Hepatic encephalopathy (HE) is a common cause of hospitalization in patients with cirrhosis. Pharmacologic treatment for acute (overt) HE has remained the same for decades. OBJECTIVE:To compare polyethylene glycol 3350-electrolyte solution (PEG) and lactulose treatments in patients with cirrhosis admitted to the hospital for HE. We hypothesized that rapid catharsis of the gut using PEG may resolve HE more effectively than lactulose. DESIGN, SETTING, AND PARTICIPANTS:The HELP (Hepatic Encephalopathy: Lactulose vs Polyethylene Glycol 3350-Electrolyte Solution) study is a randomized clinical trial in an academic tertiary hospital of 50 patients with cirrhosis (of 186 screened) admitted for HE. INTERVENTIONS:Participants were block randomized to receive treatment with PEG, 4-L dose (n?=?25), or standard-of-care lactulose (n?=?25) during hospitalization. MAIN OUTCOMES AND MEASURES:The primary end point was an improvement of 1 or more in HE grade at 24 hours, determined using the hepatic encephalopathy scoring algorithm (HESA), ranging from 0 (normal clinical and neuropsychological assessments) to 4 (coma). Secondary outcomes included time to HE resolution and overall length of stay. RESULTS:A total of 25 patients were randomized to each treatment arm. Baseline clinical features at admission were similar in the groups. Thirteen of 25 patients in the standard therapy arm (52%) had an improvement of 1 or more in HESA score, thus meeting the primary outcome measure, compared with 21 of 23 evaluated patients receiving PEG (91%) (P?<?.01); 1 patient was discharged before final analysis and 1 refused participation. The mean (SD) HESA score at 24 hours for patients receiving standard therapy changed from 2.3 (0.9) to 1.6 (0.9) compared with a change from 2.3 (0.9) to 0.9 (1.0) for the PEG-treated groups (P?=?.002). The median time for HE resolution was 2 days for standard therapy and 1 day for PEG (P?=?.01). Adverse events were uncommon, and none was definitely study related. CONCLUSIONS AND RELEVANCE:PEG led to more rapid HE resolution than standard therapy, suggesting that PEG may be superior to standard lactulose therapy in patients with cirrhosis hospitalized for acute HE.
