BACKGROUND: PEG-based laxatives are considered today the gold standard for the treatment of constipation in children. PEG formulations differ in terms of composition of inactive ingredients which may have an impact on acceptance, compliance and adherence to treatment. We therefore compared the efficacy, tolerability, acceptance and compliance of a new PEG-only formulation compared to a reference PEG-electrolyte (PEG-EL) formulation in resolving faecal impaction and in the treatment of chronic constipation. METHODS: Children aged 2–16 years with functional chronic constipation for at least 2 months were randomized to receive PEG-only 0.7 g/kg/day in 2 divided doses or 6.9 g PEG-EL 1–4 sachets according to age for 4 weeks. Children with faecal impaction were randomized to receive PEG-only 1.5/g/kg in 2 divided doses until resolution or for 6 days or PEG-EL with an initial dose of 4 sachets and increasing 2 sachets a day until resolution or for 7 days. RESULTS: Ninety-six children were randomized into the study. Five patients withdrew consent before starting treatment. Three children discontinued treatment for refusal due to bad taste of the product (1 PEG-only, 2 PEG-EL); 1 (PEG-EL) for an adverse effect (abdominal pain). Intent-to-treat analysis was carried out in 49 children in the PEG-only group and 42 in the PEG-EL group.No significant differences were observed between the two treatment groups at baseline.Adequate relief of constipation in terms of normalized frequency and painless defecation of soft stools was achieved in all patients in both groups. The number of stools/week was 9.2 +/- 3.2 (mean +/- SD) in the PEG-only group and 7.8 +/- 2.4 in the PEG-EL group (p = 0.025); the number of days with stool was 22.4 +/- 5.1 in the PEG-only group and 19.6 +/- 7.2 in the PEG-EL group (p = 0.034).In the PEG-only group faecaloma resolution was observed in 5 children on the second day and in 2 children on the third day, while in the PEG-EL group it was observed in 2 children on the second day, in 3 children on the third day and in 1 child on the fifth day.Only 2 patients reported mild treatment-related adverse events: 1 child in the PEG-only group had diarrhoea and vomiting and 1 child in the PEG-EL group had abdominal pain requiring treatment discontinuation. The PEG-only preparation was better tolerated as shown by the lower frequency of nausea than in the PEG-EL group.In the PEG-only group, 96% of patients did not demonstrate any difficulties associated with treatment, as compared with 52% of patients in the PEG-EL group (p < 0.001). Also, the PEG-only formulation taste was better than that of PEG-EL (p < 0.001). The difference between the percentage of subjects who took > 80% of the prescribed dose was in favour of the PEG-only group (98% vs. 88%), though it did not reach a conventional statistical level (p = 0.062). CONCLUSION: PEG-only was better tolerated and accepted than PEG-EL in children with chronic constipation. At the higher PEG doses recommended by the manufactures children in the PEG-only group had higher and more regular soft stool frequency than PEG-EL.Trial NCT01592734.

Malone antegrade continence enemas are used in the management of neurogenic bowel to attain fecal continence. Several different irrigation solutions have been described but glycerin, an osmotic laxative that promotes peristalsis, has rarely been mentioned or studied. We assessed clinical outcomes in our patients with a Malone antegrade continence enema using glycerin based irrigation.

Study design:Cross-sectional study.Objective:To evaluate the long-term effect of the sacral anterior root stimulator (SARS) on neurogenic bowel dysfunction in a large, well defined spinal cord injury (SCI) cohort.Setting:Department of Neuro-Urology, Bad Wildungen, Germany.Methods:Subjects undergone surgery at for SARS-SDAF (sacral deafferentation) between September 1986 and July 2011 (n=587) answered a questionnaire. In total, 277 SARS subjects were available for the baseline (recall) and follow-up comparison.Results:Median age was 49 years (range: 19-80), time from SCI to surgery was 10 years (range: 0-49) and from surgery to follow-up 13 (range: 1-25). Of the responders 73% used SARS for bowel emptying. On visual analog scale (VAS) ranging from 0-10 (best), satisfaction with SARS was 10. Baseline and follow-up comparison showed a decline in the median VAS score 0-10 (worst) for bowel symptoms from 6 (range: 4-8) to 4 (range: 2-6), P<0.0001; median neurogenic bowel dysfunction score from 17 (range: 11-2) to 11 (range: 9-15), P<0.0001; median St Marks score from 4 (range: 0-7) to 4 (range: 0-5), P=0.01; and median Cleveland constipation score from 7 (range: 6-10) to 6 (range: 4-8), P<0.0001. Use of suppositories, digital evacuation and mini enema and subjects totally dependent on assistance during defecation were significantly lower after SARS.Conclusions:The SARS has the potential to be one of the few treatment methods targeting multiple organ dysfunctions following SCI.Spinal Cord advance online publication, 20 January 2015; doi:10.1038/sc.2015.2.

5-aminosalicylic acid (5-ASA) is drug of choice for the treatment of ulcerative colitis (UC). In this study, the efficacy of topical versus oral 5-ASA for the treatment of UC was examined as well as the action mechanism of this medication. A flexible tube was inserted into the rat cecum to establish a topical administration model of 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced UC. A total of 60 rats were divided into sham operation group (receiving an enema of 0.9% saline solution instead of the TNBS solution via the tube), model group, topical 5-ASA group, oral Etiasa group (a release agent of mesalazine used as positive control) and oral 5-ASA group (n=12 each). Different treatments were administered 1 day after UC induction. The normal saline (2 mL) was instilled twice a day through the tube in the sham operation group and model group. 5-ASA was given via the tube in the topical 5-ASA group (7.5 g/L, twice per day, 100 mg/kg), and rats in the oral Etiasa group and oral 5-ASA group intragastrically received Etiasa (7.5 g/L, twice per day, 100 mg/kg) and 5-ASA (7.5 g/L, twice per day, 100 mg/kg), respectively. The body weight was recorded every day. After 7 days of treatment, blood samples were drawn from the heart to harvest the sera. Colonic tissues were separated and prepared for pathological and related molecular biological examinations. The concentrations of 5-ASA were detected at different time points in the colonic tissues, feces and sera in different groups by using the high pressure liquid chromatography (HPLC). The results showed that the symptoms of acute UC, including bloody diarrhea and weight loss, were significantly improved in topical 5-ASA-treated rats. The colonic mucosal damage, both macroscopical and histological, was significantly relieved and the myeloperoxidase activity was markedly decreased in rats topically treated with 5-ASA compared with those treated with oral 5-ASA or Etiasa. The mRNA and protein expression of IL-1β, IL-6, and TNF-α was down-regulated in the colonic tissue of rats topically treated with 5-ASA, significantly lower than those from rats treated with oral 5-ASA or Etiasa. The concentrations of 5-ASA in the colonic tissue were significantly higher in the topical 5-ASA group than in the oral 5-ASA and oral Etiasa groups. It was concluded that the topical administration of 5-ASA can effectively increase the concentration of 5-ASA in the colonic tissue, decrease the expression of proinflammatory cytokines, alleviate the colonic pathological damage and improve the symptoms of TNBS-induced acute UC in rats.

OBJECTIVES:: Colonic dysbiosis contributes to the development of colonic inflammation in ulcerative colitis (UC). Fecal microbial transplantation (FMT) is being proposed as a novel treatment for UC as it can eliminate dysbiosis. However, no prospective data exists. We initiated a pilot study to evaluate feasibility and safety of FMT in children with UC. METHODS:: Ten children, 7 to 21 years of age, with mild to moderate UC (pediatric ulcerative colitis activity index [PUCAI] between 15 and 65) received freshly prepared fecal enemas daily for 5 days. Data on tolerability, adverse events and disease activity were collected during FMT and weekly for 4 weeks after FMT. Clinical response was defined as decrease in PUCAI by >15 and decrease in PUCAI to <10 was considered clinical remission. RESULTS:: No serious adverse events were noted. Mild (cramping, fullness, flatulence, bloating, diarrhea and blood in stool) to moderate (fever) adverse events were self-limiting. One subject could not retain fecal enemas. Average tolerated enema volume by remaining nine subjects was 165 mL/day. After FMT, seven out of the nine (78%) subjects showed clinical response within 1 week, six out of the nine (67%) subjects maintained clinical response at 1 month, and three out of the nine (33%) subjects achieved clinical remission at 1 week after FMT. Median PUCAI significantly improved after FMT (p = 0.03) compared to the baseline. CONCLUSIONS:: Fecal enemas were feasible and tolerated by children with UC. Adverse events were acceptable, self-limiting and manageable by subjects. FMT indicated efficacy in the treatment of UC.

Laxative-refractory opioid-induced constipation (OIC) is defined as OIC despite using 2 laxatives with a different mechanism of action (based on the Anatomical Therapeutic Chemical Classification System level 4 term [contact laxatives, osmotically acting laxatives, softeners/emollients, enemas, and others]). OIC has a significant impact on the treatment and quality of life of patients with severe chronic pain. This noninterventional, observational, real-life study in Belgium investigated the efficacy of prolonged-release oxycodone/naloxone combination (PR OXN) treatment regarding pain relief and OIC compared with previous prolonged-release oxycodone (PR OXY) treatment for laxative-refractory OIC in daily clinical practice.
