Abstract
Objective

Granulocyte–monocyte apheresis (GMA) has shown to be safe and effective in ulcerative colitis (UC), also in combination with biologics, mainly with anti-TNF. The aim of this study was to evaluate the efficacy and safety of combining GMA after primary non-response (PNR) or loss of response (LOR) to ustekinumab (UST) in patients with UC.

Patients and methods

A retrospective study was performed in 12 IBD Units, including all patients with refractory UC or unclassified IBD (IBD-U) who received combined GMA plus UST. The number and frequency of GMA sessions, filtered blood volume and time of each session were registered. Efficacy was assessed 1 and 6 months after finishing GMA by partial Mayo score, C-reactive protein (CRP) and fecal calprotectin (FC). Descriptive statistics and non-parametric tests were used in the statistical analysis.

Results

Seventeen patients were included (15 UC, 2 IBD-U; median age 47 years [IQR, 35–61]; 59% male; 53% E3). Most patients (89%) had prior exposure to anti-TNF agents and 53% to vedolizumab; 65% were also receiving steroids at baseline. Median partial Mayo score at baseline was 6 (IQR, 5–7) and it significantly decreased after 1 and 6 months (p=0.042 and 0.007, respectively). Baseline FC significantly decreased after 6 months (p=0.028) while no differences were found in CRP. During follow-up, 18% patients started a new biologic therapy and 12% required surgery; 64% of patients under steroids were able to discontinue them. Adverse events were reported in one patient.

Conclusion

GMA can recapture the response to UST in selected cases of UC after PNR or LOR to this drug.

Resumen
Objetivo

La granulocito-monocito aféresis (GMA) ha demostrado ser segura y eficaz en el tratamiento de la colitis ulcerosa (CU), incluso en combinación con fármacos biológicos, especialmente anti-TNF. El objetivo de este estudio fue evaluar la eficacia y la seguridad de la combinación de GMA y ustekinumab (UST) tras falta de respuesta primaria o pérdida de respuesta a este fármaco en pacientes con CU.

Pacientes y métodos

Estudio retrospectivo realizado en 12 Unidades de EII que incluyó a todos los pacientes con CU refractaria o EII no clasificada que recibieron GMA más UST. La eficacia se evaluó 1 y 6 meses después de finalizar la GMA mediante la puntuación de Mayo parcial, la proteína C reactiva (PCR) y la calprotectina fecal (CF). El análisis estadístico se realizó mediante análisis descriptivos y pruebas no paramétricas.

Resultados

Se incluyeron 17 pacientes (mediana 47 años [RIC: 35-61]; 59% mujeres; 53% E3). La mayoría de los pacientes (89%) habían recibido previamente anti-TNF y un 53% vedolizumab; el 65% también recibían esteroides concomitantes. La mediana de la puntuación de Mayo parcial basal fue de 6 (RIC: 5-7), y disminuyó significativamente tras 1 y 6 meses (p=0,042 y 0,007, respectivamente). La CF disminuyó significativamente tras 6 meses (p=0,028) y no se encontraron diferencias en la PCR. Durante el seguimiento, el 18% de los pacientes iniciaron un nuevo fármaco biológico y un 12% requirieron cirugía; el 64% de los pacientes tratados con esteroides pudieron suspenderlos. Se registraron efectos adversos en un paciente.

Conclusión

La GMA podría recuperar la respuesta a UST en casos seleccionados de CU tras la falta de respuesta primaria o pérdida de respuesta a este fármaco.
