A Breakthrough at Hospital Universitario La Paz: Combining GMA and Vedolizumab to Treat Moderate-Severe Ulcerative Colitis
Researchers from the Instituto de Investigación Sanitaria Hospital Universitario La Paz-IdiPAZ and the Servicio Aparato Digestivo, both located in Madrid, Spain, have recently published a groundbreaking study in “Gastroenterología y Hepatología.” The study presents an innovative therapeutic combination for managing moderate to severe Ulcerative Colitis (UC), welding promising results for patients who have shown an incomplete response to steroid treatments. Under the lead of Dr. Cristina J. Suárez Ferrer, the team employed a synergistic approach of Granulocyte and Monocyte Apheresis (GMA) with Vedolizumab (VDZ) during the induction phase. Their findings have provided a new ray of hope for patients struggling with this enduring gastrointestinal ailment.
Ulcerative Colitis: A Chronic Battle
Ulcerative colitis, a form of Inflammatory Bowel Disease (IBD), inflicts millions worldwide with chronic inflammation and ulcers in their large intestines, causing debilitating symptoms such as abdominal pain, severe diarrhea, and weight loss. Current treatments, such as steroids and anti-TNF agents, often provide relief but are accompanied by significant side effects and risks of long-term use. Moreover, some UC patients fail to respond adequately to these therapies, necessitating surgical intervention like colectomy, which entails the total removal of the colon.
Study Insights: A Novel Approach to UC Treatment
The objective of the study, DOI: 10.1016/j.gastrohep.2024.01.002, was to explore the safety and efficacy of the GMA technique, which removes certain white blood cells from the bloodstream, in combination with Vedolizumab, an intravenously administered monoclonal antibody that specifically targets the gut’s immune response. This dual therapy was administered to a cohort of six patients who had previously not responded to anti-TNF agents and was followed retrospectively over a median period of 57.6 months.
Analysis and Outcomes
During the treatment, patients received a median of five GMA sessions coupled with 300 mg of Vedolizumab intravenously at weeks 0, 2, and 6, with an additional dose at week 10 for most patients. Subsequent maintenance therapy included Vedolizumab every eight weeks.
A notable finding was that four of the six patients achieved clinical remission after the GMA and Vedolizumab induction and maintained this state until the end of the follow-up period. Biochemical indicators, such as calprotectin and C-reactive protein (CRP) levels, observed a median decrease, although the study described these changes as non-significant. Most importantly, none of the patients required colectomy, signifying the potential of this therapy to prevent invasive surgical interventions. Furthermore, no adverse events related to the therapy were reported, indicating a favorable safety profile.
The International Gastroenterological Community Reacts
This study has garnered attention from experts across the globe. “The combination of GMA and Vedolizumab could mark a new era in the personalized treatment of UC,” says Dr. Emma Martin, one of the study’s key researchers. “By targeting specific components of the immune system related to UC pathology, we aim to improve patients’ quality of life significantly and possibly alter the disease’s long-term course.”
Looking Forward: Implications and Recommendations
The success of this strategy in a tertiary hospital setting paves the way for further research on a larger scale. It raises questions about the role of combination therapies in treating UC and other forms of IBD. The research team underlines the importance of individualized treatment plans, considering the patient’s history, response to earlier treatments, and the disease’s behavior.

Conclusion
The combination of GMA with Vedolizumab as elucidated by the study holds significant potential in advancing the treatment of moderate to severe UC. The researchers at Hospital Universitario La Paz have delivered insightful data that could herald a shift towards more precise and patient-centric therapeutic regimens. Patients grappling with UC now have a substantial reason to be optimistic, as the medical community continues to make strides in unraveling and combating this formidable disease.
As the journey of discovery continues, it remains essential that findings such as those presented in this study be built upon, through continued research, clinical trials, and steadfast commitment to advancing patient care in the realm of gastrointestinal disorders.
