An eight-strain probiotic has been shown to reduce the risk for pouchitis in patients with ulcerative colitis who undergo ileal pouch anal anastomosis (IPAA), but its cost-effectiveness depends on relapse risk and may only be justified in patients who experience frequent relapses of pouchitis, a new analysis showed.

“Our findings highlight that while probiotic treatments can reduce the risk of this complication, their high costs limit their overall value for most patients,” lead author Gaurav Syal, MD, a gastroenterologist at UCLA Health, said in a statement.

“Our analysis can help guide shared decision-making between patients, clinicians, and payers to ensure resources are used where they can provide the most benefit,” Syal added.

The study was published online in Gastro Hep Advances.

 

Common Complication After Ulcerative Colitis Surgery

Pouchitis is a common complication in patients with ulcerative colitis who undergo restorative proctocolectomy with IPAA, with a cumulative incidence of around 48% at 2 years and 80% at 30 years.

Many patients who experience pouchitis have a single episode and respond well to short antibiotic courses. However, others develop recurrent or relapsing pouchitis, and 17% progress to a chronic form that can become dependent on antibiotics or refractory to antibiotics.

An eight-strain probiotic was shown to be effective in primary and secondary prevention of pouchitis in randomized, placebo-controlled trials.

Syal and colleagues sought to determine whether it’s worth the cost.

They constructed decision-tree models with Markov simulations to compare the risk for initial development and recurrence of pouchitis over a 2-year period between no prophylaxis and daily use of the eight-strain probiotic.

In the primary prophylaxis model, the cycle length was 2 weeks and pouchitis treatment sequence was ciprofloxacinmetronidazole and ciprofloxacin-tinidazole. In the secondary prophylaxis model, the cycle length was 4 weeks and pouchitis treatment sequence was initially the same as the primary prophylaxis model with the addition of vedolizumab and infliximab.

Costs were calculated from a US third-party payer perspective, using a willingness-to-pay threshold of $100,000 per quality-adjusted life year (QALY).

For primary prevention, the probiotic slightly increased QALYs compared with no probiotic (0.927 vs 0.918) but at a far higher cost ($2223 vs $299), resulting in an incremental cost-effectiveness ratio (ICER) of $236,076 per QALY — well above the accepted threshold.

In patients with infrequent relapses, probiotic use was slightly more effective than no use of probiotic (cumulative QALYs, 1.26 vs 1.24) but more expensive ($3370 vs $557), yielding an ICER of $153,011 per QALY — again above the accepted threshold.

However, sensitivity analyses revealed that the probiotic was cost-effective in patients with frequent relapsing pouchitis — defined as two or more episodes per year.

In this subgroup, the ICER dropped below the willingness-to-pay threshold of $100,000 per QALY, and in some scenarios, the probiotic even became the dominant strategy, meaning it was both more effective and less costly than no prophylaxis, the researchers noted.

Current guidelines from AGA on managing pouchitis suggest using probiotics to prevent recurrent episodes of pouchitis with a caveat that those who experience infrequent episodes may choose to avoid secondary prevention strategies.

“Our findings supplement the guidelines by confirming that the eight-strain probiotics can be cost-effective in frequent relapsing not in infrequent relapsing pouchitis,” the authors wrote.

They also noted that the probiotic cost itself was the biggest driver of results, accounting for 95% of the total cost in the primary prevention model. According to their analysis, reducing its price by half could make it a cost-effective option more broadly.

They also noted that probiotic prophylaxis could be cost-effective for patients at higher-than-average risk, such as those with primary sclerosing cholangitis (PSC), who have 4.2 times higher odds of developing pouchitis than peers without PSC.

But they cautioned that “further research is warranted on the effectiveness of the eight-strain probiotic for primary prevention of pouchitis in patients with ulcerative colitis and IPAA and PSC.”

The study had no financial support. Syal reported receiving research support from Pfizer.
