BACKGROUND Glucose tolerance abnormalities including cystic fibrosis related diabetes (CFRD) are common in patients with cystic fibrosis (CF). The underlying pathophysiology is not fully understood. Emerging evidence suggests that CFTR dysfunction may directly or indirectly impact β-cell function, offering the potential for improvement with CFTR modulator therapy. In small pilot studies, treatment with ivacaftor improved insulin secretion in patients with the G551D CFTR mutation. In the current study, we examined the impact of lumacaftor/ivacaftor therapy on glucose tolerance and insulin secretion in patients with CF who were homozygous for the F508del mutation. METHODS 39 subjects from the PROSPECT Part B study who had been prescribed lumacaftor/ivacaftor by their CF care team at a CF Foundation's Therapeutic Development Network center were recruited. Subjects underwent 2-hour oral glucose tolerance tests (OGTTs) at baseline prior to first dose of lumacaftor/ivacaftor, and at 3, 6 and 12 months on therapy. OGTT glucose, insulin and c-peptide parameters were compared. RESULTS Compared to baseline, OGTT fasting and 2 hour glucose levels, glucose area under the curve, insulin area under the curve and time to peak insulin level were not significantly different at 3, 6 and 12 months on lumacaftor/ivacaftor therapy. Similarly, C-peptide levels were no different. CONCLUSIONS Lumacaftor/ivacaftor therapy did not improve insulin secretion or glucose tolerance in patients with CF who were homozygous for the F508del mutation.

Lumacaftor/ivacaftor 治疗未能增加 F508del/F508del CF 患者的胰岛素分泌

背景技术包括囊性纤维化相关糖尿病(CFRD)在内的葡萄糖耐量异常在囊性纤维化(CF)患者中很常见。潜在的病理生理学尚不完全清楚。新出现的证据表明,CFTR 功能障碍可能直接或间接影响 β 细胞功能,为 CFTR 调节剂治疗提供了改善的潜力。在小型试点研究中,ivacaftor 治疗可改善 G551D CFTR 突变患者的胰岛素分泌。在目前的研究中,我们检查了 lumacaftor/ivacaftor 治疗对 F508del 突变纯合子 CF 患者的葡萄糖耐量和胰岛素分泌的影响。方法 PROSPECT B 部分研究中的 39 名受试者,他们在 CF 基金会的 CF 护理团队开具了 lumacaftor/ivacaftor' s 治疗发展网络中心被招募。受试者在首次给药 lumacaftor/ivacaftor 之前的基线以及治疗 3、6 和 12 个月时接受了 2 小时口服葡萄糖耐量测试 (OGTT)。比较了OGTT葡萄糖、胰岛素和c肽参数。结果 与基线相比,在 lumacaftor/ivacaftor 治疗 3、6 和 12 个月时,OGTT 空腹和 2 小时血糖水平、曲线下葡萄糖面积、曲线下胰岛素面积和达到峰值胰岛素水平的时间没有显着差异。同样,C 肽水平也没有什么不同。结论 Lumacaftor/ivacaftor 治疗并未改善 F508del 突变纯合子 CF 患者的胰岛素分泌或葡萄糖耐量。受试者在首次给药 lumacaftor/ivacaftor 之前的基线以及治疗 3、6 和 12 个月时接受了 2 小时口服葡萄糖耐量测试 (OGTT)。比较了OGTT葡萄糖、胰岛素和c肽参数。结果 与基线相比,在 lumacaftor/ivacaftor 治疗 3、6 和 12 个月时,OGTT 空腹和 2 小时血糖水平、曲线下葡萄糖面积、曲线下胰岛素面积和达到峰值胰岛素水平的时间没有显着差异。同样,C 肽水平也没有什么不同。结论 Lumacaftor/ivacaftor 治疗并未改善 F508del 突变纯合子 CF 患者的胰岛素分泌或葡萄糖耐量。受试者在首次给药 lumacaftor/ivacaftor 之前的基线以及治疗 3、6 和 12 个月时接受了 2 小时口服葡萄糖耐量测试 (OGTT)。比较了OGTT葡萄糖、胰岛素和c肽参数。结果 与基线相比,在 lumacaftor/ivacaftor 治疗 3、6 和 12 个月时,OGTT 空腹和 2 小时血糖水平、曲线下葡萄糖面积、曲线下胰岛素面积和达到峰值胰岛素水平的时间没有显着差异。同样,C 肽水平也没有什么不同。结论 Lumacaftor/ivacaftor 治疗并未改善 F508del 突变纯合子 CF 患者的胰岛素分泌或葡萄糖耐量。在 lumacaftor/ivacaftor 治疗 3、6 和 12 个月时,葡萄糖曲线下面积、胰岛素曲线下面积和达到峰值胰岛素水平的时间没有显着差异。同样,C 肽水平也没有什么不同。结论 Lumacaftor/ivacaftor 治疗并未改善 F508del 突变纯合子 CF 患者的胰岛素分泌或葡萄糖耐量。在 lumacaftor/ivacaftor 治疗 3、6 和 12 个月时,葡萄糖曲线下面积、胰岛素曲线下面积和达到峰值胰岛素水平的时间没有显着差异。同样,C 肽水平也没有什么不同。结论 Lumacaftor/ivacaftor 治疗并未改善 F508del 突变纯合子 CF 患者的胰岛素分泌或葡萄糖耐量。
