OBJECTIVE: Acute Uncomplicated Diverticulitis (AUD) is defined as the inflammation of a colon diverticulum, often involving colic wall and pericolic fat. Conventional treatment of AUD includes antibiotics, usually ciprofloxacin and metronidazole, fasting, and fluid therapy. The aim of this study was to test the efficacy of a mix of three probiotic strains (Bifidobacterium lactis LA 304, Lactobacillus salivarius LA 302, Lactobacillus acidophilus LA 201; Lactibiane Iki®, Biocure [PiLeJe Groupe], Italy/PiLeJe Laboratoire, France) in association with conventional antibiotics in treating AUD compared to conventional antibiotics used alone.
PATIENTS AND METHODS: We enrolled 84 (25M/59F mean age 61.5 ± 11.5 years) consecutive patients who came to the Emergency Department of the Fondazione Policlinico Universitario A. Gemelli – IRCCS, Rome, Italy, with a diagnosis of AUD confirmed by CT scan. After routine blood test and dosage of C-reactive protein (C-RP), patients were randomly divided into two groups: Probiotic group (42 patients, 10M/32F mean age 62.23 ± 10.3 years) was treated with ciprofloxacin 400 mg twice a day and metronidazole 500 mg three times a day for one week and simultaneously supplemented with the probiotic mix, 1 sachet twice a day for 10 days. Control group (42 patients, 15M/27F mean age 59.01 ± 11.3 years) received the same antibiotic treatment without the probiotic mix. All patients filled a daily Visual Analog Scale (VAS) for assessment of abdominal pain, with a range value from 0 (asymptomatic) to 10, and CRP value was determined on admission and at discharge.
RESULTS: As regards abdominal pain, on Day 3, Group A showed a significant decrease of 4.06 points (51.4%) in VAS score compared to a decrease of 2.79 points (34.9%) in Group B. On Day 5 the decrease was of 6.3 points (80%) in Group A and of 4.85 points (61%) in Group B. VAS score was reduced by 7.59 points (96%) in Group A and 6.1 points (76%) in Group B on Day 7 +, and by 7.8 points (99%) in Group A and 7.2 points (90%) in Group B on Day 10. About inflammation, Group A showed a decrease in C-RP value of 64%, compared to a decrease of only 35% in Group B. We also observed that the duration of hospitalization was significantly shorter for patients in Group A: 89 h (3.7 days) in Group A vs. 101 h (4.2 days) in Group B (p=0.03).
CONCLUSIONS: Our results indicated showed that the supplement with the probiotic mix of Bifidobacterium lactis LA 304, Lactobacillus salivarius LA 302, and Lactobacillus acidophilus LA 201 in combination with the standard antibiotic therapy for AUD reduced abdominal pain and inflammation significantly more than antibiotic treatment used alone. These findings could be due to the anti-inflammatory activity of the probiotic mix. Larger studies are needed to validate its use in the clinical practice.
