The standard therapeutic approach for symptomatic uncomplicated diverticular disease (DD) remains to be defined, and only a few studies have tested the efficacy of probiotics in these patients.


Patients with symptomatic uncomplicated DD were randomized to a control arm, i.e., (group A, [N.=16], high-fibre diet alone), or to Group B ([n=18], twice daily 1 sachet of probiotic + high-fibre diet), or group C ([N.=16], twice daily 2 sachets of probiotic + high-fibre diet). The probiotic Genefilus F19© containing Lactobacillus paracasei sub. paracasei F19 was administered for 14 days/month for 6 months. The primary endpoint under consideration was a decrease in abdominal pain and bloating intensity after treatment.


Bloating decreased significantly in Groups B and C VAS score group B: 4.6 ± 2.6 vs. 2.3 ± 2.0, P<0.05, group C: 3.9 ± 2.9 vs. 1.8 ± 2.1, P<0.05). The decrease in abdominal pain within 24 hours in these groups did not reach statistical significance. During treatment, none of the group B (N.=4) or group C patients (N=3) with abdominal pain >24 hours reported the recurrence of this symptom, while the 3 group A patients reported at least one episode (P=0.016). No significant difference regarding abdominal pain <24 hours and bloating was observed between the two groups of patients treated with a low or high probiotic dose.


Lactobacillus paracasei F19, in association with a high-fibre diet, is effective in reducing abdominal bloating and prolonged abdominal pain in symptomatic uncomplicated diverticular disease, and could thus be a promising option in the treatment of these patients.
