Agreement of site and central readings of ileocolonoscopic scores in Crohn's disease: comparison using data from the EXTEND trial

Background and AimsCentralized endoscopic scoring may reduce variability, but evidence is lacking in patients with Crohn’s disease. We assessed the agreement of endoscopic scorings between site endoscopists and one central reader by using data from the adalimumab Crohn’s disease clinical trial EXTEND.MethodsAgreement between readers for Crohn’s Disease Endoscopic Index of Severity (CDEIS)–scored endoscopies from 6 sites and Simple Endoscopic Score for Crohn’s Disease (SES-CD)–scored endoscopies from 19 sites in EXTEND was evaluated at baseline and weeks 12 and 52. Agreement on total scores was calculated by using intraclass correlation coefficient (ICC). Kappa statistic or Spearman correlation coefficient measured the agreement between readers for each ileocolonic segment on CDEIS variables including deep ulceration, surface involved, and ulcerated surface and SES-CD variables including ulcerated surface, size of ulcers, and affected surface.ResultsICCs on mean scores at baseline and weeks 12 and 52 were 0.78, 0.92, and 0.86 (CDEIS), and 0.77, 0.86, and 0.82 (SES-CD), respectively. Site endoscopists consistently reported higher scores. High agreement was observed for most segments and all time points for CDEIS variables and SES-CD large ulcers. Weak agreement occurred for the right side of the colon at all time points for CDEIS deep ulceration and SES-CD large ulcers and at baseline and week 12 for CDEIS ulcerated surface. Fair/moderate agreement occurred for SES-CD ulcerated surface and moderate/high agreement for affected surface for all segments and time points.ConclusionsSite and central readers showed high agreement on total CDEIS and SES-CD scores overall, whereas variability for individual segments was observed. Weakest agreement occurred at baseline, with a greater difference for SES-CD than for CDEIS score. (Clinical trial registration number: NCT00348283.

Four-year maintenance treatment with adalimumab in patients with moderately to severely active ulcerative colitis:data from ULTRA 1, 2, and 3

OBJECTIVES: The safety and efficacy of adalimumab for patients with moderately to severely active ulcerative colitis (UC) has been reported up to week 52 from the placebo-controlled trials ULTRA (Ulcerative Colitis Long-Term Remission and Maintenance with Adalimumab) 1 and 2. Up to 4 years of data for adalimumab-treated patients from ULTRA 1, 2, and the open-label extension ULTRA 3 are presented. METHODS: Remission per partial Mayo score, remission per Inflammatory Bowel Disease Questionnaire (IBDQ) score, and mucosal healing rates were assessed in adalimumab-randomized patients from ULTRA 1 and 2 up to week 208. Corticosteroid-free remission was assessed in adalimumab-randomized patients who used corticosteroids at lead-in study baseline. Maintenance of remission per partial Mayo score and mucosal healing was assessed in patients who entered ULTRA 3 in remission per full Mayo score and with mucosal healing, respectively. As observed, last observation carried forward (LOCF) and nonresponder imputation (NRI) were used to report efficacy. Adverse events were reported for any adalimumab-treated patient. RESULTS: A total of 600/1,094 patients enrolled in ULTRA 1 or 2 were randomized to receive adalimumab and included in the intent-to-treat analyses of the studies. Of these, 199 patients remained on adalimumab after 4 years of follow-up. Rates of remission per partial Mayo score, remission per IBDQ score, mucosal healing, and corticosteroid discontinuation at week 208 were 24.7%, 26.3%, 27.7% (NRI), and 59.2% (observed), respectively. Of the patients who were followed up in ULTRA 3 (588/1,094), a total of 360 patients remained on adalimumab 3 years later. Remission per partial Mayo score and mucosal healing after ULTRA 1 or 2 to year 3 of ULTRA 3 were maintained by 63.6% and 59.9% of patients, respectively (NRI). Adverse event rates were stable over time. CONCLUSIONS: Remission, mucosal healing, and improved quality of life were maintained in patients with moderately to severely active UC with long-term adalimumab therapy, for up to 4 years. No new safety signals were reported

Long-Term Efficacy and Safety of Adalimumab in Pediatric Patients with Crohn's Disease

Background: IMAgINE 1 assessed 52-week efficacy and safety of adalimumab in children with moderate to severe Crohn's disease. Long-Term efficacy and safety of adalimumab for patients who entered the IMAgINE 2 extension are reported. Methods: Patients who completed IMAgINE 1 could enroll in IMAgINE 2. Endpoints assessed from weeks 0 to 240 of IMAgINE 2 were Pediatric Crohn's Disease Activity Index remission (Pediatric Crohn's Disease Activity Index ≤ 10) and response (Pediatric Crohn's Disease Activity Index decrease ≥15 from IMAgINE 1 baseline) using observed analysis and hybrid nonresponder imputation (hNRI). For hNRI, discontinued patients were imputed as failures unless they transitioned to commercial adalimumab (with study site closure) or adult care, where last observation was carried forward. Corticosteroid-free remission in patients receiving corticosteroids at IMAgINE 1 baseline, discontinuation of immunomodulators (IMMs) in patients receiving IMMs at IMAgINE 2 baseline, and linear growth improvement were reported as observed. Adverse events were assessed for patients receiving ≥1 adalimumab dose in IMAgINE 1 and 2 through January 2015. Results: Of 100 patients enrolled in IMAgINE 2, 41% and 48% achieved remission and response (hNRI) at IMAgINE 2 week 240. Remission rates were maintained by 45% (30/67, hNRI) of patients who entered IMAgINE 2 in remission. At IMAgINE 2 week 240, 63% (12/19) of patients receiving corticosteroids at IMAgINE 1 baseline achieved corticosteroid-free remission and 30% (6/20) of patients receiving IMMs at IMAgINE 2 baseline discontinued IMMs. Adalimumab treatment led to growth velocity normalization. No new safety signals were identified. Conclusions: Efficacy and safety profiles of prolonged adalimumab treatment in children with Crohn's disease were consistent with IMAgINE 1 and adult Crohn's disease adalimumab trials

Efficacy and safety of upadacitinib in a randomized trial of patients with Crohn’s disease

Background & Aims: We evaluated the efficacy and safety of upadacitinib, an oral selective Janus kinase 1 inhibitor, in a randomized trial of patients with Crohn's disease (CD). Methods: We performed a double-blind, phase 2 trial in adults with moderate to severe CD and inadequate response or intolerance to immunosuppressants or tumor necrosis factor antagonists. Patients were randomly assigned (1:1:1:1:1:1) to groups given placebo; or 3 mg, 6 mg, 12 mg, or 24 mg upadacitinib twice daily; or 24 mg upadacitinib once daily and were evaluated by ileocolonoscopy at weeks 12 or 16 of the induction period. Patients who completed week 16 were re-randomized to a 36-week period of maintenance therapy with upadacitinib. The primary endpoints were clinical remission at week 16 and endoscopic remission at week 12 or 16 using the multiple comparison procedure and modeling and the Cochran-Mantel-Haenszel test, with a 2-sided level of 10%. Results: Among the 220 patients in the study, clinical remission was achieved by 13% of patients receiving 3 mg upadacitinib, 27% of patients receiving 6 mg upadacitinib (P < .1 vs placebo), 11% of patients receiving 12 mg upadacitinib, and 22% of patients receiving 24 mg upadacitinib twice daily, and by 14% of patients receiving 24 mg upadacitinib once daily, vs 11% of patients receiving placebo. Endoscopic remission was achieved by 10% (P < .1 vs placebo), 8%, 8% (P < .1 vs placebo), 22% (P < .01 vs placebo), and 14% (P < .05 vs placebo) of patients receiving upadacitinib, respectively, vs none of the patients receiving placebo. Endoscopic but not clinical remission increased with dose during the induction period. Efficacy was maintained for most endpoints through week 52. During the induction period, patients in the upadacitinib groups had higher incidences of infections and serious infections vs placebo. Patients in the twice-daily 12 mg and 24 mg upadacitinib groups had significant increases in total, high-density lipoprotein, and low-density lipoprotein cholesterol levels compared with patients in the placebo group. Conclusions: In a phase 2 trial of patients with CD, upadacitinib induced endoscopic remission in a significant proportion of patients compared with placebo. Upadacitinib's benefit/risk profile supports further development for treatment of CD. (Clinicaltrials.gov, Number: NCT02365649

Primary Aldosteronism: A Practical Approach to Diagnosis and Treatment

Primary aldosteronism (PA) may account for as many as 10%–14% of hypertension cases. The plasma aldosterone concentration/plasma renin activity ratio is a simple screening test for PA that should be performed in all patients with refractory/severe hypertension, spontaneous or provoked (by diuretics) hypokalemia, or a requirement for excessive potassium supplementation to maintain normokalemia. PA can be confirmed by a fludrocortisone suppression test or 24‐hour urine collection for aldosterone. Confirmatory testing should be followed by high‐resolution computerized tomography of the adrenal glands to distinguish bilateral hyperplasia or an adenoma. A solitary tumor greater than 1 cm in size in a younger patient is an indication for surgery; all other (nondiagnostic) findings should be followed by bilateral adrenal venous sampling (if available) to identify a unilateral cause of PA. Treatment for a later alizing positive study is surgical; spironolactone or another mineralocorticoid receptor antagonist is the treatment of choice for a nonlateralizing study. If adrenal venous sampling is not readily available, patients may be successfully treated pharmacologically

Hyperaldosteronism Among Black and White Subjects With Resistant Hypertension

Recent reports suggesting that the prevalence of primary hyperaldosteronism may be higher than historically thought have relied on an elevated plasma aldosterone concentration/plasma renin activity ratio to either diagnose or identify subjects at high risk of having primary hyperaldosteronism and have not included suppression testing of all evaluated subjects. In this prospective study of 88 consecutive patients referred to a university clinic for resistant hypertension, we determined the 24-hour urinary aldosterone excretion during high dietary salt ingestion, baseline plasma renin activity, and plasma aldosterone in all subjects. Primary hyperaldosteronism was confirmed if plasma renin activity was 12 μg/24-hour during high urinary sodium excretion (>200 mEq/24-hour). Eighteen subjects (20%) were confirmed to have primary hyperaldosteronism. The prevalence of hyperaldosteronism was similar in black and white subjects. Of the 14 subjects with confirmed hyperaldosteronism who have been treated with spironolactone, all have manifested a significant reduction in blood pressure. In this population, an elevated plasma aldosterone/plasma renin activity ratio (>20) had a sensitivity of 89% and a specificity of 71% with a corresponding positive predictive value of 44% and a negative predictive value of 96%. These data provide strong evidence that hyperaldosteronism is a common cause of resistant hypertension in black and white subjects. The accuracy of these results is strengthened by having done suppression testing of all evaluated subjects
