Effectiveness and Safety of Ustekinumab in Elderly Patients with Crohn's Disease: Real World Evidence From the ENEIDA Registry.

BACKGROUND AND AIMS: Clinical trials and real-life studies with ustekinumab in Crohn's disease [CD] have revealed a good efficacy and safety profile. However, these data are scarcely available in elderly patients. Therefore, we aim to assess the effectiveness and safety of ustekinumab in elderly patients with CD. METHODS: Elderly patients [>60 years old] from the prospectively maintained ENEIDA registry treated with ustekinumab due to CD were included. Every patient was matched with two controls under 60 years of age, according to anti-tumour necrosis factor use and smoking habit. Values for the Harvey-Bradshaw Index [HBI], endoscopic activity, C-reactive protein [CRP] and faecal calprotectin [FC] were recorded at baseline and at weeks 16, 32 and 54. RESULTS: In total, 648 patients were included, 212 of whom were elderly. Effectiveness was similar between young and elderly patients during the follow-up. Steroid-free remission was similar at week 16 [54.6 vs 51.4%, p = 0.20], 32 [53.0% vs 54.5%, p = 0.26] and 54 [57.8% vs 51.1%, p = 0.21]. Persistence of ustekinumab as maintenance therapy was similar in both age groups [log-rank test; p = 0.91]. There was no difference in the rate of adverse effects [14.2% vs 11.2%, p = 0.350], including severe infections [7.1% vs 7.3%, p = 1.00], except for the occurrence of de novo neoplasms, which was higher in older patients [0.7% vs 4.3%, p = 0.003]. CONCLUSIONS: Ustekinumab is as effective in elderly patients with CD as it is in non-elderly patients. The safety profile also seems to be similar except for a higher rate of de novo neoplasms, probably related to the age of the elderly patients.

Amyloidosis and Crohn´s disease.

Secondary amyloidosis is a rare but serious complication of inflammatory bowel disease that may influence the prognosis even more than the underlying disease. Due to a better knowledge of the association of secondary amyloidosis to inflammatory bowel disease, early diagnosis of this complication is becoming more frequent, but its treatment continues to pose a challenge. We report 4 cases of patients with Crohn´s disease and amyloidosis diagnosed in the inflammatory bowel disease Units of Toledo and Ciudad Real, which represent 0.68% of the patients with Crohn´s disease of our health areas. There have been not cases of amyloidosis in patients with ulcerative colitis. In our 4 patients the secondary amyloidosis was clearly related to Crohn´s disease,which was often of fistulising type. The predominant clinical picture of amyloidosis was nephrotic syndrome. The patients responded to medical and surgical treatment of Crohn´s disease and colchicine, which improved renal function in all cases except in one who required kidney transplantation.

Amiloidosis y enfermedad de Crohn / Amyloidosis and Crohn's disease

La amiloidosis sistémica adquirida es una complicación rara pero grave de la enfermedad inflamatoria intestinal crónica, pudiendo condicionar el pronóstico más que la propia enfermedad de base. Debido al mejor conocimiento de la asociación de amiloidosis secundaria a enfermedad inflamatoria intestinal, el diagnóstico temprano se hace cada vez con mayor frecuencia, pero su tratamiento continúa siendo un reto. Describimos 4 casos clínicos de pacientes con enfermedad de Crohn (EC) y amiloidosis diagnosticados en las Unidades de EIIC de Toledo y Ciudad Real, lo que representa el 0,68% de los caso de EC de nuestras áreas sanitarias. No se ha descrito ningún caso de amiloidosis en pacientes con colitis ulcerosa. En los 4 pacientes la AA estaba claramente relacionada con la EC, y predominaron las formas estenosantes-perforantes. El cuadro clínico de presentación de la amiloidosis en la mayoría de los casos fue un síndrome nefrótico. Los pacientes respondieron al tratamiento médico-quirúrgico de la EC y a la colchicina, con lo que mejoró la función renal en todos los casos salvo en uno que precisó trasplante renal(AU)
