Advancing Access to Intestinal Microbiota Transplant: Bridging the Gap Between National Practices and the European Strategy.

Clostridioides difficile is an opportunistic pathogen that can cause a range of conditions, from asymptomatic carriage to severe illness, posing a significant public health threat due to its high mortality rates and substantial healthcare costs. Traditional treatment options, including antibiotics, often fail to eradicate the infection, leading to recurrent cases that severely impact patients' lives. Intestinal microbiota transplant (IMT) has emerged as an effective strategy for decolonizing pathogenic agents, demonstrating safety and efficacy, particularly in treating recurrent Clostridioides difficile infection (rCDI). Despite its potential, access to IMT is limited due to safety concerns, logistical challenges, and a lack of proper guidance, underscoring the urgent need for structured intestinal microbiota banks (IMBs). These organized facilities are crucial for the collection, screening, processing, and distribution of intestinal microbiota preparations, thereby facilitating the clinical application of IMT. In this narrative review, we discuss the relevance of applying IMT for the treatment of rCDI in Europe, with a focus on Portugal. We highlight the existence and distribution of IMBs across Europe and their importance in improving access to IMT. This review also addresses the challenges in creating an IMB and the development of such a structure in Portugal as a centralized repository for high-quality, standardized microbiota preparations, making IMT accessible for national hospitals. Additionally, it emphasizes the need to raise awareness among healthcare providers and the public to support the broader adoption of IMT.
