ABSTRACT

BACKGROUND: Evidence has shown beneficial effects of probiotics in the treatment of irritable bowel syndrome (IBS); however, there is still a lack of data in this regard. We evaluated the efficacy of a multi-strain probiotic compound on IBS symptoms and quality-of-life (QOL). MATERIALS AND METHODS: Adult IBS patients (n = 132) were randomized to receive a probiotic compound containing seven bacteria species including Lactobacillus strains, Bifidobacterium strains and Streptococcus thermophiles or similar placebo, twice daily after a meal for 14 consecutive days. Improvement of IBS symptoms was assessed in categories of abdominal pain and distension and improvement of bowel habit. Improvement in patients QOL was assessed by the IBS-QOL instrument. Patients were evaluated for symptoms and QOL at baseline and then 1 month after completion of the treatment. RESULTS: After treatment, there was a decrease in abdominal pain and distension severity in both probiotic and the placebo groups (P<0.001), but there was no difference between the two groups in this regard (P>0.05). Improvement in bowel habit was observed in 33.3% of the probiotic and 36.5% of the placebo group (P = 0.910). There was no significant difference between the two groups in QOL after the treatment (P >0.05). CONCLUSIONS: We found no beneficial effects over placebo for a 2-week treatment with the above mentioned multi-strain probiotic compound in the treatment of IBS. Further, trials are yet required before a clear conclusion in this regards.

ABSTRACT

BACKGROUND: Recently, higher efficacy of the combination of long-acting beta2-adrenoceptor agonist and inhaled corticosteroids on controlling asthma symptoms has been hypothesized. This study aimed to examine the clinical effects of the combination of Budesonide with formoterol (Symbicort) and Budesonide (Pulmicort) alone in persistent asthma. MATERIALS AND METHODS: In a randomized double-blinded clinical trial, 76 patients with definite diagnosis of moderate-to-severe asthma were randomized to receive Pulmicort 180 mcg/inhalation two puffs twice daily, or receive Symbicort 80/4.5 mg/inhalation two puffs twice daily, or receive Symbicort 160/4.5 mg/inhalation two puffs twice daily for 3 months. All participants were initially evaluated by spirometry for assessing respiratory parameters and also the level of asthma control was assessed by Asthma Control Test (ACT). RESULTS: More significant improvement in spirometry parameters, including forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, as well as in peak expiratory flow (PEF) in both groups of Symbicort with the regimens 80/4.5 mg/inhalation or 160/4.5 mg/inhalation 2 puffs twice daily compared with Pulmicort group, ACT score was significantly improved in Symbicort group with the regimens 160/4.5 mg/inhalation compared with both Symbicort groups with lower dosage and Pulmicort group. Response to treatment in PEF parameter and also in ACT level was significantly more in those who received Symbicort with the regimens 160/4.5 mg/inhalation compared with other two interventional groups adjusted for gender and age. CONCLUSION: Symbicort with the regimens 160/4.5 mg/inhalation has higher efficacy in reducing asthma symptom and improving its control compared with low doses of this drug and with Pulmicort.
