The introduction of elexacaftor/tezacaftor/ivacaftor (ETI) therapy has further extended life expectancy of adults with cystic fibrosis (awCF), highlighting the need for increased attention to potential long-term health issues. Given the increasing prevalence of cardiovascular diseases in the ageing population and the presence of cardiovascular risk factors associated with CF, understanding the impact of ETI on cardiometabolic risk factors is a crucial clinical concern. The aim of our prospective observational study was to explore early changes in cardiac and metabolic biomarkers after 6 months of ETI therapy. A total of 58 consecutive awCF were enrolled during clinical stability at the Adult CF Center of the Policlinico Hospital in Milan, Italy between January 2021 and June 2022. Blood samples were obtained before ETI initiation and after 6 months, and underwent central processing for an extended panel of cardiometabolic biomarkers. We observed a rise in cholesterol, triglycerides, apolipoprotein-B and adipokine levels, while inflammatory markers decreased. The direct relationship between leptin and adiponectin suggest a disruption in the normal regulatory mechanisms that control these hormones, potentially leading to metabolic imbalances, such as increased risk of obesity and cardiovascular events. The impact of ETI on cardiovascular risk in awCF is heterogeneous and while it improves some risk factors, such as chronic inflammation, it has a worsening effect on lipoproteins. Our findings suggest that the dysregulation of adipokines could be a potential cause of the metabolic disturbances observed in awCF.
elexaftor /tezacaftor/ivacaftor (ETI)疗法的引入进一步延长了囊性纤维化(awCF)成人患者的预期寿命,突出了对潜在长期健康问题的更多关注的必要性。鉴于老龄化人群中心血管疾病患病率的增加以及与CF相关的心血管危险因素的存在,了解ETI对心脏代谢危险因素的影响是一个至关重要的临床问题。本前瞻性观察性研究的目的是探讨ETI治疗6个月后心脏和代谢生物标志物的早期变化。2021年1月至2022年6月,在意大利米兰Policlinico医院成人CF中心的临床稳定期间,共有58例连续的awCF患者入组。在ETI开始前和6个月后采集血液样本,并进行中央处理,以获得一组扩展的心脏代谢生物标志物。我们观察到胆固醇、甘油三酯、载脂蛋白b和脂肪因子水平上升,而炎症标志物下降。瘦素和脂联素之间的直接关系表明,控制这些激素的正常调节机制受到破坏,可能导致代谢失衡,如肥胖和心血管事件的风险增加。ETI对awCF患者心血管风险的影响是不均匀的,虽然它改善了一些危险因素,如慢性炎症,但它对脂蛋白的影响却恶化了。我们的研究结果表明,脂肪因子的失调可能是awCF中观察到的代谢紊乱的潜在原因。

Background

A highly effective therapy involving elexacaftor, tezacaftor, and ivacaftor (ETI) for cystic fibrosis (CF) patients has recently raised safety concerns regarding potential psychiatric disorders. The manuscript reports cases of suicide attempts in patients receiving ETI and investigates putative causality using the WHO spontaneous reporting database.

Methods

First, four cases of suicide attempts/self-injury are described. Second, a disproportionality analysis was conducted using spontaneous reports collected in Vigibase through the standardised MedDRA Query (narrow version) "Suicide/Self-injury" and ETI exposure. Reporting Odds Ratio (ROR) was calculated for the main and subgroup (i/suicide attempt, ii/suicidal ideation) analyses. Sensitivity analyses were performed with variations in exposure, to ivacaftor/lumacaftor to assess the intrinsic psychiatric risk of CF patients, and paracetamol as a positive control for suicide attempt and a negative one for suicidal ideation. Exposure to reduced-dose ETI was studied to evaluate the dose-gradient effect.

Results

Four cases of suicide attempt/self-injury occurred 3 to 13 months after ETI initiation in CF patients and were reported to the Bordeaux Pharmacovigilance centre. Aside, in Vigibase, ETI is associated with an increased likelihood of reporting suicidal behaviour (ROR 2.5, 95 % CI[2.1; 2.8]). A signal of disproportionate reporting was found for the subgroup of suicide attempts (1.4, 95 % CI[1.2; 1.8]), unlike ivacaftor/lumacaftor, which was associated only with the risk of reporting suicidal ideation. Significant ROR values were also found for reduced-dose ETI for all psychiatric effects studied except suicide attempt.

Conclusions

ETI exposure is related with increased reporting of suicidal behaviour. A potential dose-dependent effect merits further investigation.
背景:针对囊性纤维化(CF)患者的一种高效疗法,包括 elexacaftor、tezacaftor 和 ivacaftor (ETI),最近引发了有关潜在精神障碍的安全问题。本手稿报告了接受 ETI 治疗的患者自杀未遂的病例,并利用世界卫生组织自发报告数据库调查了可能的因果关系:方法:首先,描述了四例自杀未遂/自伤病例。方法:首先,介绍了四例自杀未遂/自伤病例;其次,通过标准化 MedDRA 查询(狭义版)"自杀/自伤 "和 ETI 暴露,利用 Vigibase 收集的自发报告进行了比例失调分析。主分析和亚组(i/自杀未遂,ii/自杀意念)分析均计算了报告几率比(ROR)。进行了敏感性分析,以伊伐卡夫托/卢马卡夫托暴露的变化来评估CF患者内在的精神疾病风险,并将扑热息痛作为自杀未遂的阳性对照和自杀意念的阴性对照。研究了减量ETI的暴露情况,以评估剂量梯度效应:结果:4例自杀未遂/自伤病例发生在CF患者服用ETI 3至13个月后,波尔多药物警戒中心收到了相关报告。此外,在 Vigibase 中,ETI 与报告自杀行为的可能性增加有关(ROR 2.5,95 % CI[2.1;2.8])。在自杀未遂亚组(1.4,95 % CI[1.2;1.8])中发现了过度报告的信号,这与 ivacaftor/lumacaftor 不同,后者仅与报告自杀意念的风险有关。在研究的所有精神影响中,除自杀企图外,减量ETI也发现了显著的ROR值:结论:ETI暴露与自杀行为报告的增加有关。潜在的剂量依赖效应值得进一步研究。

Background

Inhibiting ENaC in the airways of people with cystic fibrosis (pwCF) is hypothesized to enhance mucociliary clearance (MCC) and provide clinical benefit. Historically, inhaled ENaC blockers have failed to show benefit in pwCF challenging this hypothesis. It is however unknown whether the clinical doses were sufficient to provide the required long duration of action in the lungs and questions whether a novel candidate could offer advantages where others have failed?

Methods

Dose-responses with the failed ENaC blockers (VX-371, BI 1265162, AZD5634, QBW276) together with ETD001 (a novel long acting inhaled ENaC blocker) were established in a sheep model of MCC and were used to predict clinically relevant doses that would provide a long-lasting enhancement of MCC in pwCF. In each case, dose predictions were compared with the selected clinical dose.

Results

Each of the failed candidates enhanced MCC in the sheep model. Translating these dose-response data to human equivalent doses, predicted that substantially larger doses of each candidate, than were evaluated in clinical studies, would likely have been required to achieve a prolonged enhancement of MCC in pwCF. In contrast, ETD001 displayed a long duration of action (≥16 h) at a dose level that was well tolerated in Phase 1 clinical studies.

Conclusions

These data support that the ENaC blocker hypothesis is yet to be appropriately tested in pwCF. ETD001 has a profile that enables dosing at a level sufficient to provide a long duration of action in a Phase 2 clinical study in pwCF scheduled for 2024.
背景:据推测,抑制囊性纤维化患者(pwCF)气道中的 ENaC 可提高粘液纤毛清除率(MCC)并带来临床益处。从历史上看,吸入式 ENaC 阻断剂未能在囊性纤维化患者中显示出益处,这对这一假设提出了挑战。然而,临床剂量是否足以在肺部提供所需的长效作用尚不得而知,因此有人质疑新型候选药物是否能在其他药物失败的情况下提供优势?在绵羊 MCC 模型中建立了失败的 ENaC 阻滞剂(VX-371、BI 1265162、AZD5634、QBW276)与 ETD001(一种新型长效吸入式 ENaC 阻滞剂)的剂量反应,并用于预测可持久增强 pwCF 中 MCC 的临床相关剂量。在每种情况下,预测剂量都与选定的临床剂量进行了比较:结果:每种失败的候选药物都能增强绵羊模型中的 MCC。将这些剂量-反应数据转换为人体等效剂量后,预测每种候选药物都可能需要比临床研究中评估的剂量大得多的剂量,才能在 pwCF 中实现 MCC 的持久增强。相比之下,ETD001的作用持续时间较长(≥16小时),且剂量水平在1期临床研究中耐受性良好:这些数据证明,ENaC阻断剂假说尚未在pwCF中得到适当验证。ETD001 的特性使其剂量足以在计划于 2024 年进行的 pwCF 2 期临床研究中提供较长的作用时间。

Rationale

CF care guidelines recommend chronic inhaled antibiotics for chronic Pseudomonas aeruginosa (Pa) lung infection. These medications are costly, time consuming and prescription needs may change with improved outcomes.

Objectives

We determined the proportion of pwCF with chronic, intermittent or negative Pa infection categories, their clinical and demographic characteristics, factors associated with inhaled antibiotic prescription and changes between 2011 and 2019.

Methods

This cohort study using the U.S. CF Foundation patient registry for pwCF >2 years, no prior lung transplant, and with ≥3 respiratory cultures/year determined chronic inhaled antibiotics (≥3 months per calendar year) and Pa infection status from encounter level data. Outcomes and odds of prescription for relevant clinical factors were evaluated using generalized estimating equation models with additional interaction between the predictor and the calendar year to examine changes of predictors over time.

Results

Proportion of pwCF with chronic and intermittent Pa decreased and antibiotic prescription rates increased for these groups and decreased for Pa negative pwCF. Hispanic ethnicity, female sex, pancreatic insufficiency, CF diabetes, and ivacaftor/lumacaftor were associated with higher antibiotic prescriptions for each Pa status. Among Pa-negative pwCF prescriptions were higher with Burkholderia spp. (1.17, (CI95 1.03,1.34)) or MRSA (OR 1.45, (1.26,1.68)) but decreased between 2011 and 2019. For Aspergillus OR increased to 1.6,(1.3,1.8) in 2019. Prescriptions for pwCF on ivacaftor decreased, becoming lower in 2019 for chronic (OR 0.7, (0.5,0.8)) and Pa-negative pwCF (OR 0.7, (0.5,0.8)).

Conclusions

Factors predicting inhaled antibiotic prescription differed between 2011 and 2019 indicating changes in health and care for pwCF even prior to triple-modulators.
依据:CF 护理指南推荐使用慢性吸入抗生素治疗慢性绿脓杆菌(Pa)肺部感染。这些药物成本高、耗时长,而且处方需求可能会随着治疗效果的改善而改变:我们确定了患有慢性、间歇性或阴性 Pa 感染类别的 pwCF 比例、他们的临床和人口统计学特征、与吸入式抗生素处方相关的因素以及 2011 年至 2019 年间的变化:这项队列研究使用了美国 CF 基金会患者登记处的数据,研究对象为年龄大于 2 岁、既往未进行过肺移植、呼吸道培养次数≥3 次/年的 pwCF,通过会诊数据确定慢性吸入抗生素(每个日历年≥3 个月)和 Pa 感染状态。使用广义估计方程模型评估了相关临床因素的结果和处方几率,并在预测因素和日历年之间添加了交互作用,以检查预测因素随时间的变化:结果:患有慢性和间歇性帕金森病的患儿比例下降,这些群体的抗生素处方率上升,帕金森病阴性患儿的抗生素处方率下降。西班牙裔、女性、胰腺功能不全、CF 糖尿病和 ivacaftor/lumacaftor 与每种 Pa 状态下的抗生素处方率较高有关。在 Pa 阴性 pwCF 中,伯克霍尔德氏菌(1.17,(CI95 1.03,1.34))或 MRSA(OR 1.45,(1.26,1.68))的处方量较高,但在 2011 年至 2019 年期间有所下降。曲霉菌 OR 在 2019 年增至 1.6,(1.3,1.8)。使用伊伐卡夫托的 pwCF 的处方量有所下降,2019 年慢性 pwCF(OR 0.7,(0.5,0.8))和 Pa 阴性 pwCF(OR 0.7,(0.5,0.8))的处方量有所下降:预测吸入抗生素处方的因素在 2011 年和 2019 年之间存在差异,表明即使在使用三联调节剂之前,pwCF 的健康和护理也发生了变化。

Glucagon-like-peptide-1 (GLP-1) agonists are commonly used to improve glycemic control and promote weight loss in individuals with type 2 diabetes mellitus (T2DM) and/or obesity. However, there is a paucity of evidence regarding GLP-1 agonist use in people with cystic fibrosis (pwCF). We present 11 people with CF (males: 3, females: 7; age range 24–47; BMI range 25.7–43.7) treated with GLP-1 agonists (semaglutide: 9,tirzepatide: 2) for variable duration (1–50 months). All experienced weight loss on GLP- 1 agonist therapy (median change in weight = -7.2 kg; change in BMI [kg/m2] = -0.9 to -8.1). Eight pwCF showed improvement in percent predicted forced expiratory volume in 1 second (ppFEV1) [change = -5 to + 18] and nine pwCF showed improvement in percent predicted forced vital capacity (ppFVC) [change= +1 to + 26]. Of the 7 pwCF with CFRD, all reduced their insulin quantity (mean, 31.5 % decrease in total daily insulin dose), and glucose time in range improved for most (mean, +11 % increase from baseline). Four pwCF stopped using GLP-1 agonists: 2 due to severe nausea/vomiting, 1 due to lack of perceived benefit, and 1 due to change in insurance coverage. This report is the largest published series to date of pwCF treated with GLP-1 agonist therapy.

胰高血糖素样肽-1(GLP-1)激动剂常用于改善 2 型糖尿病(T2DM)和/或肥胖症患者的血糖控制并促进减肥。然而,有关囊性纤维化患者(pwCF)使用 GLP-1 激动剂的证据却很少。我们介绍了 11 名囊性纤维化患者(男性:3 人,女性:7 人;年龄范围:24-47 岁;体重指数范围:25.7-43.7)接受 GLP-1 激动剂(司马鲁肽:9 人,替扎帕肽:2 人)治疗的情况,治疗时间长短不一(1-50 个月)。所有患者在接受 GLP-1 激动剂治疗后体重都有所下降(体重变化中位数 = -7.2千克;体重指数(BMI)[kg/m2] 变化 = -0.9 至 -8.1)。8 名患者的 1 秒内预测用力呼气容积 (ppFEV1) 百分比有所改善[变化 = -5 至 + 18],9 名患者的预测用力肺活量 (ppFVC) 百分比有所改善[变化 = +1 至 + 26]。在 7 名患有 CFRD 的患儿中,所有患儿都减少了胰岛素用量(平均每日胰岛素总剂量减少 31.5%),大多数患儿的血糖在范围内的时间有所改善(平均比基线增加 11%)。有 4 名患者停止使用 GLP-1 激动剂:2 人因严重恶心/呕吐而停止使用,1 人因认为缺乏益处而停止使用,1 人因保险范围发生变化而停止使用。本报告是迄今为止发表的最大规模的使用 GLP-1 激动剂治疗帕金森病的系列报告。在添加 GLP-1 激动剂后,所有患者的体重都减轻了,每日胰岛素剂量也减少了,而且大多数患者的肺功能都得到了改善。未来还需要进行多中心研究,以证实这些药物在 CF 患者中的疗效和安全性。

Background

Highly effective CFTR modulator therapy (HEMT) has improved the health of many people with cystic fibrosis (pwCF), offering opportunities to discontinue burdensome therapies. SIMPLIFY included randomized, controlled trials that confirmed non-inferiority of discontinuing versus continuing dornase alfa (DA) or hypertonic saline (HS) for 6 weeks in pwCF on HEMT. In this study of post-trial treatment use by SIMPLIFY participants, we hypothesized that randomization to discontinue DA or HS during the trial would be associated with a higher likelihood of non-use of each medication during follow-up.

Methods

We electronically surveyed SIMPLIFY participants every 4 weeks for 24 weeks after trial completion but before the main trial results were publicly disclosed. We asked them how often they used medications during the previous week. We estimated covariate-adjusted odds ratios (ORs) of DA or HS non-use by logistic regression with generalized estimating equations.

Results

After exclusions mostly due to lack of any surveys, 472 participants were included in the analysis population, 181 from the HS trial and 291 from the DA trial. Approximately half of the analysis population completed all six surveys. At every month of follow-up in both trials, the percentage of individuals reporting non-use of DA or HS during the previous week was greater among those randomized to discontinue therapy. Among participants with responses at 24 weeks, 30/122 (24.6 %) in the HS trial and 79/222 (35.6 %) in the DA trial reported non-use of the respective study medication. After adjusting for covariates, participants randomized to discontinue DA were 8.7-times (95 % CI: 4.3–17.7) more likely to not use DA during follow-up than those randomized to continue DA, and participants randomized to discontinue HS were 5.2-times (95 % CI: 2.1–12.8) more likely to not use HS during follow-up compared to those randomized to continue.

Conclusions

In healthy pwCF on ETI, randomization to discontinue DA or HS during SIMPLIFY was associated with greater odds of not using each medication after the trial compared to randomization to continue. These findings suggest that participation in a treatment discontinuation trial can influence participants’ post-trial treatment decisions. This possibility may be relevant during discussions about research participation and clinical care.
背景:高效的 CFTR 调节剂疗法(HEMT)改善了许多囊性纤维化患者(pwCF)的健康状况,为他们提供了中止繁重疗法的机会。SIMPLIFY 纳入的随机对照试验证实,在接受 HEMT 治疗的囊性纤维化患者中,停用多纳酶α(DA)或高渗盐水(HS)6 周与继续使用多纳酶α或高渗盐水(HS)相比无劣效性。在这项关于 SIMPLIFY 参与者试验后治疗使用情况的研究中,我们假设在试验期间随机停用 DA 或 HS 与随访期间不使用每种药物的可能性较高有关:在试验结束后、主要试验结果公开之前的 24 周内,我们每 4 周对 SIMPLIFY 参与者进行一次电子调查。我们询问了他们上周使用药物的频率。我们通过使用广义估计方程的逻辑回归估算了经协方差调整的DA或HS不使用的几率比(ORs):主要由于缺乏任何调查而被排除后,472 名参与者被纳入分析人群,其中 181 人来自 HS 试验,291 人来自 DA 试验。大约一半的分析人群完成了全部六项调查。在这两项试验的每个月的随访中,报告在前一周未使用 DA 或 HS 的人数比例在随机中止治疗的人群中更高。在 24 周时有回复的参与者中,HS 试验中有 30/122 人(24.6%)和 DA 试验中有 79/222 人(35.6%)报告未使用相应的研究药物。调整协变量后,随机停用DA的参与者在随访期间不使用DA的可能性是随机继续DA者的8.7倍(95 % CI:4.3-17.7),随机停用HS的参与者在随访期间不使用HS的可能性是随机继续HS者的5.2倍(95 % CI:2.1-12.8):结论:在接受 ETI 治疗的健康男性和女性患者中,与随机选择继续治疗相比,在 SIMPLIFY 试验期间随机选择停用 DA 或 HS 与试验结束后不使用每种药物的几率更大相关。这些研究结果表明,参与终止治疗试验会影响参与者试验后的治疗决定。在讨论参与研究和临床治疗时,这种可能性可能与之相关。

Background

The constellation of hypertension, truncal obesity, impaired fasting glucose, low high-density lipoprotein, and hypertriglyceridemia is known as metabolic syndrome (MetSyn) and is associated with cardiovascular and other diseases. Elexacaftor-tezacaftor-ivacaftor (ETI) in people with cystic fibrosis (pwCF) is associated with weight gain but effects on cardiovascular risk are unknown. This study sought to investigate ETI exposure and risk for development of MetSyn in pwCF.

Methods

A prospective cohort study including pwCF ≥ 18 years old exposed to ETI was performed. All data for calculating MetSyn was collected from the electronic medical record at initiation and 1 year ± 3 months after starting ETI. A total of 152 pwCF exposed to ETI and 34 pwCF never exposed to CF transmembrane conductance regulator modulators were included in the analysis. Changes to hypertension classification was also examined over this period.

Results

After 1 year of ETI there was an increase in MetSyn from 13 to 30 pwCF, p < 0.0001. No new cases of MetSyn were seen in the group not exposed to ETI. After 1 year of ETI, more people met criteria for class 1 (BP 130–139/90–99 mm Hg) or class 2 hypertension (BP ≥140/≥90 mm Hg) regardless of prior modulator exposure, p < 0.0001.

Conclusions

Exposure to ETI for 1 year resulted in an increased number of cases of MetSyn. There was an increased incidence of hypertension associated with ETI exposure. Additional studies are needed to further examine this trend and to determine if these changes will translate to cardiovascular complications over time.
背景:高血压、躯干肥胖、空腹血糖受损、低高密度脂蛋白和高甘油三酯血症被称为代谢综合征(MetSyn),与心血管疾病和其他疾病相关。囊性纤维化患者(pwCF)服用 Elexacaftor-tezacaftor-ivacaftor (ETI) 会导致体重增加,但对心血管风险的影响尚不清楚。本研究旨在调查囊性纤维化患者的 ETI 暴露和 MetSyn 的发病风险:方法:进行了一项前瞻性队列研究,研究对象包括暴露于 ETI 的年龄≥ 18 岁的 pwCF。用于计算 MetSyn 的所有数据均来自开始使用 ETI 和使用 ETI 1 年 ± 3 个月后的电子病历。共有 152 名接触过 ETI 的儿童和 34 名从未接触过 CF 跨膜电导调节剂的儿童被纳入分析。在此期间,还对高血压分类的变化进行了研究:使用 ETI 1 年后,MetSyn 从 13 例增加到 30 例,p < 0.0001。未接触过 ETI 的人群中没有出现新的 MetSyn 病例。使用 ETI 1 年后,更多的人达到了 1 级高血压(血压 130-139/90-99 mm Hg)或 2 级高血压(血压≥140/≥90 mm Hg)标准,无论之前是否接触过调节剂,P < 0.0001:暴露于 ETI 1 年会导致 MetSyn 病例增加。高血压发病率的增加与暴露于 ETI 有关。需要进行更多的研究来进一步研究这一趋势,并确定这些变化是否会随着时间的推移转化为心血管并发症。

Background

Cystic Fibrosis (CF) patients historically suffered from undernutrition, infection and inflammation. Insulin insufficiency-related protein catabolism further compromised health. We aimed to determine whether insulin improves protein catabolism in CF youth with abnormal glucose tolerance (AGT).

Methods

This double-masked, placebo-controlled trial in CF youth age 10–25 with AGT who were in their usual state of health used triple-tracer stable-isotope methodology to measure protein turnover during a baseline test meal and after four weeks of insulin/placebo treatment. Healthy controls were assessed once. CF patients were randomized 1:1:1 to once-daily long-acting insulin (0.25 U/kg/d), three-times daily rapid-acting insulin (0.5 U/15gr carbohydrate), or injectable placebo.

Results

Thirty CF patients completed the study. There were no differences in any measure of protein turnover between insulin- and placebo-treated subjects, including endogenous protein breakdown (primary study endpoint). In contrast to earlier studies, protein turnover in the 37 CF patients who completed the baseline meal was normal compared to 20 healthy controls. Meal isotope appeared in plasma earlier in CF than controls, suggesting more rapid gut emptying. The study was interrupted by the pandemic; futility analysis led to study discontinuation before the planned remaining 15 CF patients were studied.

Conclusions

Recent advances in CF have led to remarkable clinical improvements. In this study, CF youth with AGT had normal protein catabolism at baseline. Pre-meal or daily basal insulin therapy, while safe and well tolerated, did not significantly enhance protein turnover and does not appear to be necessary in clinically stable patients prior to development of CFRD.
背景:囊性纤维化(CF)患者历来饱受营养不良、感染和炎症之苦。与胰岛素不足有关的蛋白质分解进一步损害了患者的健康。我们旨在确定胰岛素是否能改善糖耐量异常(AGT)的 CF 青少年的蛋白质分解代谢:这项双掩蔽、安慰剂对照试验以 10-25 岁、患有 AGT 且处于正常健康状态的 CF 青少年为对象,采用三重示踪剂稳定同位素方法,测量基线测试餐期间和胰岛素/安慰剂治疗四周后的蛋白质代谢情况。健康对照组接受一次评估。CF患者按1:1:1的比例随机接受每日一次的长效胰岛素(0.25 U/kg/d)、每日三次的速效胰岛素(0.5 U/15gr碳水化合物)或注射安慰剂治疗:30名CF患者完成了研究。胰岛素治疗和安慰剂治疗的受试者在蛋白质周转的任何指标上都没有差异,包括内源性蛋白质分解(主要研究终点)。与之前的研究相比,37 名完成基线餐的 CF 患者与 20 名健康对照组相比,蛋白质周转率正常。与对照组相比,CF 患者血浆中出现膳食同位素的时间更早,这表明肠道排空更快。这项研究因大流行病而中断;无用性分析导致在对计划中剩余的 15 名 CF 患者进行研究之前中止了研究:结论:CF 的最新研究进展已使临床症状得到显著改善。在这项研究中,患有 AGT 的 CF 青少年基线蛋白质分解代谢正常。餐前或每日基础胰岛素治疗虽然安全且耐受性良好,但并不能显著提高蛋白质的转化率,因此临床稳定的患者在出现 CFRD 之前似乎没有必要接受这种治疗。
