Tolerability and Effectiveness of Progut in Treatment of Irritable Bowel Syndrome
Assessment of Tolerability & Effectiveness of Progut in Treatment of Irritable Bowel Syndrome
Irritable bowel syndrome (IBS) is a very common chronic functional gastrointestinal disorder characterised by abdominal pain/discomfort, bloating and alterations in bowel function. This condition significantly impairs quality of life and places a large burden on health care resources. Existing therapies for IBS are far from being satisfactory and new therapies are being constantly sought.
The pathogenesis of IBS remains unclear. Imbalance in the intestinal microbiota is considered to be one important etiologic factor for IBS. That some probiotics are effective in the prevention and treatment of IBS supports this idea.
Progut is a synbiotic: a combination of probiotics and prebiotics. Probiotics are viable beneficial bacteria that are normally present in a healthy digestive tract. Each capsule of Progut contains 9 billion viable bacteria from 8 different strains that are characteristics of a healthy normal gut microflora: Lactobacillus (L. acidophilus, L. casei, L. lactis, and L. bulgaricus); Bifidobacterium (B. longum, B. infantis and B. bifidum); and Streptococcus thermophilus at time of manufacturing. To ensure survival of these bacteria, Progut is encapsulated and enteric-coated.
The primary objective is to evaluate the tolerability of Progut treatment 1-3 capsules/day in patients with irritable bowel syndrome under the same conditions as those likely to be encountered in a standard general clinical practice or outpatient clinic.
The rationale for this study is to obtain tolerability data in patients with IBS in the Singapore. The secondary objectives are to evaluate the patients' satisfaction and symptom improvement with Progut treatment.

Detailní popis
This will be an open-label, single arm post marketing surveillance study involving an active treatment period of a minimum 3-week and a maximum 12-week duration. Treatment with Progut will be at the discretion of the attending doctor and decision is independent of this study. This study will only recruit patients following the prescription of Progut and follow them up for upto a maximum of 12 weeks.
At Visit 1 (Day 1), the eligible patients will receive a prescription for Progut from their physician. Depending on the discretion of the attending physician, they will be prescribed Progut for treatment duration lasting 3 to 12 weeks. Safety of Progut under normal clinical use will be assessed at the end of this period. Perception of effectiveness, and tolerability of treatment will be assessed on Day 8-15 using a phone interview. On Visit 2 (any time between Day 22 to 85, depending on duration of treatment given and schedule of their follow-up visit arranged by the attending physician), the patient will be evaluated for symptomatic improvement, perception of effectiveness, tolerability and satisfaction with treatment, following which he/she will formally exit the study.
This study design was chosen with the aim of recruiting rapidly a large cohort of patients representative of the population being prescribed Progut. A total of 50 patients will be included to allow for an assessment of patient's tolerability of Progut, as well as satisfaction and perception of effectiveness and symptom response in the Singapore population.
