Difference in the Timing of Initiation of Biologic Therapy in Early-Onset Versus Late-Onset Inflammatory Bowel Disease (IBD): A Single Tertiary Center Experience

AbstractAim:Childhood onset inflammatory bowel disease is more aggressive and has rapidly progressive clinical course than adult inflammatory bowel disease. Early-onset inflammatory bowel disease has more severe clinical progression as a subspecialised group of monogenic inflammatory bowel disease. We studied cardiac functions and aortic elasticity in children with early- and late-onset inflammatory bowel disease in remission period.Methods:Thirty-three paediatric patients were divided into subgroups according to age of disease onset (<10 and >10 years of age). Twenty-five healthy children were admitted as control group. M-Mode echocardiography and pulsed wave Doppler echocardiography were performed. Strain, distensibility, stiffness index of ascending, and abdominal aorta were evaluated.Results:Interventricular septum (mm) and left ventricular end-systolic diameter were higher (6.9 ± 1.2, 26.2 ± 4.6) in early-onset inflammatory bowel disease patients than control patients (6.1 ± 1.27, 22.7 ± 4.12) (p = 0.050, p = 0.050). Mitral E/E′ ratio and myocardial performance index were increased in inflammatory bowel disease and early-onset inflammatory bowel disease groups than control group (p = 0.046, p = 0.04; p = 0.023, p = 0.033). Diastolic functions were found to be impaired in inflammatory bowel disease and early-onset inflammatory bowel disease groups according to control group, while there was no difference between late-onset inflammatory bowel disease and control groups in terms of diastolic functions. Mitral E/A ratio was lower in inflammatory bowel disease patients and early-onset inflammatory bowel disease patients (1.46 ± 0.32, 1.4 ± 0.21) than control patients (1.70 ± 0.27) (p = 0.013, p = 0.004). Aortic elasticity did not differ between groups.Conclusion:Chronic low-grade inflammation has effects on left ventricular diameters and diastolic function in remission period. Aortic elasticity is not affected in our study groups.

Abstract Background The incidence of very early-onset inflammatory bowel disease (VEOIBD) is on the rise in Russia but the clinical data is lacking. We aim to study the disease phenotype, clinical course and the presence of primary immunodeficiency (PID) patients in this group. Methods Clinical records of VEOIBD patients treated in Russian State Pediatric Hospital between 2000 and 2018 were revised. In 60 patients admitted between 2016 and 2018 targeted sequencing (PID panel) was performed. 10 patients received genetic testing previously. Results 135 VEOIBD patients were identified: 95 (70%)with ulcerative colitis (UC), 31 (23%) with Crohn’s disease, 9 (7%) with PID. In 14 (11%) IBD patients the diagnosis was changed from UC to CD and vice versa. Median time of diagnosis was 7 months in UC, 24 months in CD and 44 months in PID. The most common clinical symptoms were loose stools (UC—98%, CD—84%), bloody stools (UC—93, CD—65%), stomach ache (UC—53%, CD—52%), fever (UC—35%, CD—42%). Common laboratory features included anemia (UC—56%, CD—39%), low serum ferrum level (UC—75%, CD—61%), thrombocytosis (UC—53%, CD—45%). From 103 patients tested for ANCA 26% had positive results (24—UC, 3—CD). Mean calprotectin level (76 patients) was 750 ± 54.4 μg/g. Pancolitis was seen in UC (84%), as well as in CD (61%). Epithelioid granulomas in CD were present in 7 patients, in 5 of them they were detected years after initial diagnosis. Sixty-nine% of UC and 90% of CD patients received steroids as induction therapy, steroid-dependency was common (42% in UC and 55% in CD). Forty-nine% of patients with UC and 23% od CD patients received azathioprine, anti-TNF agents were used in 26% UC patients and 77% CD patients. In 35% of patients receiving anti-TNF biologic therapy was started before the age of 6 years. 23,8% of VEOIBD patients failed to achieve clinical remission. Total colectomy was performed in 11 patients, in 3 of them the diagnosis was subsequently changed to CD. Segmental resection was performed in 9 CD patients, in 3 of them while on therapy. The most common form of PID was XIAP deficiency (3 patients), 2 of them achieved endoscopic remission after allogenic stem cell transplantation. Conclusion In the VEOIBD group CD resembles UC clinically and endoscopically. A substantial number of patients requires immunosuppressive and biologic therapy before the age of 6 years. Colectomy rates are still high regardless the use of biologics. Boys with refractory VEOIBD should be screened for XIAP deficiency.

ABSTRACT Objective: To report two patients with very-early-onset inflammatory bowel disease (VEOIBD) secondary to interleukin-10 receptor (IL-10R) mutations, explore immunophenotyping data and plasma cytokine profile on these cases compared to healthy controls, and describe the phenotype of IL-10/IL-10R mutations based on a literature review. Case description: We report on two female infants referred to our tertiary center at the age of ten months, with severe colonic and perianal disease, as well as significant malnutrition, who had shown limited response to usual inflammatory bowel disease (IBD) therapy agents. In the first case, whole-exome sequencing (WES) revealed a homozygous (c.537G>A/p.T179T) mutation in exon 4 of the IL-10RA gene, while in the second patient, compound heterozygosity was identified, also in the IL-10RA gene (chr11:117.859.199 variant A>G/p.Tyr57Cys and chr11: 117.860.335 variant G>T/p.Val123Leu). Both patients underwent hematopoietic cell transplantation (HCT). Immunological work-up of these patients revealed increased IL-10 plasma levels and increased IgA. Comments: Our case reports disclose novel findings on plasma cytokine profile in IL-10R deficiency, and we describe the severe phenotype of IL-10/IL-10R deficiency that should be recognized by physicians.
