Abstract
enBackground
Postpancreatitis diabetes mellitus (PPDM) is a common metabolic sequalae of acute and chronic pancreatitis. We conducted a cross-sectional study to examine the proportion of PPDM among patients clinically diagnosed with type 2 diabetes (T2D) in Denmark and their clinical and biochemical characteristics.
Methods
We identified all past diagnoses of pancreatitis among patients in the Danish Centre for Strategic Research in Type 2 Diabetes (DD2) cohort through linkage with national health registries. Using International Classification of Diseases, Tenth Revision codes we categorized patients as PPDM and further divided them into acute/chronic subtypes (PPDM-A and PPDM-C). We assessed PPDM prevalence and examined associations with clinical and biochemical parameters using log binomial or Poisson regression to calculate age-/sex-adjusted prevalence ratios (aPRs).
Results
Among 5564 patients with a clinical diagnosis of T2D, 78 (1.4%) had PPDM. Compared to T2D, PPDM patients were more often underweight or normal weight (body mass index ≤25.0 kg/m2: aPR 2.3; 95% confidence interval [CI]: 1.6-3.2) and had lower waist-to-hip ratio (≤0.95/≤0.80 in men/women: aPRs 1.8; 95% CI: 1.2-2.7). PPDM patients had lower plasma amylase levels (<17 U/L: aPRs 2.2; 95% CI: 1.1-4.3), higher insulin sensitivity (homeostatic model assessment 2S [HOMA2S] >63: aPR 2.0; 95% CI: 1.2-3.2) and tended to have worse glycaemic control (HbA1c ≥8.0%: aPRs 1.4; 95% CI: 0.8-2.4). PPDM-A was largely indistinguishable from T2D, whereas PPDM-C had impaired insulin secretion, higher insulin sensitivity, and worse glycemic control.
Conclusions
The proportion of PPDM among patients with clinically diagnosed T2D is ~1.5% in an everyday clinical care setting. Glucose metabolism of PPDM-A is largely indistinguishable from T2D, whereas PPDM-C differs in relation to insulin secretion and sensitivity.
摘要
zh背景
胰腺炎后糖尿病(PPDM)是急性和慢性胰腺炎常见的代谢后遗症。我们进行了一项横断面研究, 以检查在丹麦临床诊断为2型糖尿病患者中 PPDM 的比例及其临床和生化特征。
方法
在丹麦2型糖尿病战略研究中心(DD2), 通过与国家健康登记处的联系, 确定了所有过去诊断的胰腺炎患者。根据第十次国际疾病与相关健康问题统计分类修订代码, 将PPDM患者进一步分为急性/慢性亚型(PPDM-a 和 PPDM-c)。评估PPDM患病率, 使用对数二项式或对数泊松回归计算年龄/性别调整患病率(aPR) , 检查与临床和生化参数的相关性。
结果
5564例临床诊断为T2D 的患者中, 78例(1.4%)患有 PPDM。与T2D相比, PPDM患者体重偏轻或正常(体重指数≤25.0 kg/m2: aPR 2.3; 95% 置信区间[ CI] : 1.6-3.2) , 腰臀比较低(男/女≤0.95/≤0.80: aPR 1.8; 95% CI: 1.2-2.7)。PPDM患者血浆淀粉酶水平较低(< 17U/L: aPRs 2.2; 95% CI: 1.1-4.3) , 胰岛素敏感性较高(稳态模型评估2S [ HOMA2S ] > 63: aPR 2.0; 95% CI: 1.2-3.2) , 血糖控制较差(HbA1c ≥8.0% : aPRs 1.4; 95% CI: 0.8-2.4)。PPDM-A 与 T2D 在很大程度上没有区别, 而 PPDM-C胰岛素分泌减弱, 胰岛素敏感性增强, 血糖控制较差。
结论
在日常临床护理环境中, 临诊断为 T2D 的患者中 PPDM 的比例约为1.5% 。PPDM-A 的葡萄糖代谢与 T2D很难区分, 而 PPDM-C 在胰岛素分泌和敏感性的方面有所不同。
