Granulocyte-monocyte apheresis: an alternative combination therapy after loss of response to anti-TNF agents in ulcerative colitis.
Scandinavian Journal of Gastroenterology 2019 April 15
OBJECTIVE: To evaluate the effectiveness and safety of the combination of granulocyte-monocyte apheresis (GMA) after loss of response (LOR) to anti-tumor necrosis factor (TNF) agents in ulcerative colitis (UC).
MATERIALS AND METHODS: A retrospective, multicenter study was performed in 11 inflammatory bowel disease (IBD) Units. Clinical remission was defined as a partial Mayo score ≤2. The effectiveness of the treatment was evaluated by the partial Mayo score and the rate of anti-TNF intensification, switch, swap or colectomy.
RESULTS: Forty-seven patients with ulcerative colitis were included (mean age 35 years, mean disease duration 52 months, 66% male and 59% extensive colitis). Twenty-three subjects were receiving infliximab, eighteen adalimumab and six golimumab. GMA was combined after a primary non-response (49%) or secondary loss of response (51%) to anti-TNF therapy. We observed a significant decrease in partial Mayo score and fecal calprotectin after GMA. Fifteen patients (32%) responded to the combination therapy without anti-TNF intensification, switch, swap or colectomy. Eight patients (17%) underwent colectomy. Two patients (4%) presented adverse events related to the technique.
CONCLUSIONS: Combination of GMA and anti-tumor necrosis factor is a safe and effective treatment after the loss of response to this biologic agents, with a significant decrease of the clinical disease activity and biomarkers, in a population with limited therapeutic alternatives.
