Introduction
Pain management in acute pancreatitis (AP) is of critical therapeutic and prognostic significance. We aimed to identify patient phenotypes in AP based on pain management strategies and evaluate their prognostic impact.
Methods
Data from two major international prospective cohort studies of AP patients (PAINAP study, n = 2119 and APPRENTICE study, n = 1544) from 141 centers worldwide were collated. Demographic data and analgesic use (within 72 h of presentation) were used for latent class analysis of binary analgesic data. The number of clusters was determined by minimisation of Bayesian information criterion. Cluster assignment and AP outcomes were interrogated with multivariable mixed-effects logistic regression.
Results
Overall, 3469 patients (median age 52; 47 % female) were analysed. There were 1015 (29.2 %) patients that had moderately severe to severe AP. Within the first 72 h, 494 (14.2 %) patients received non-steroidal anti-inflammatory drugs (NSAIDs), 1410 (40.6 %) weak opioids, 1347 (14.2 %) strong opioids, and 48 (1.4 %) epidural analgesia. There were significant variations in analgesic prescribing patterns across centers (p < 0.001, interclass correlation coefficient 43.8 %). Latent class analysis identified 5 unique patient clusters: early NSAIDs use, minimal analgesic use, strong opioid use, early multimodal analgesia use, and early weak opioid use. The cluster characterized by early NSAIDs was associated with non-severe AP (adjusted odds ratio 0.64, 95 % confidence interval 0.44–0.93, p = 0.02), which could suggest that the use of NSAIDs was perhaps driven by milder pain severity.
Conclusion
Unique clusters in the management of pain in AP were identified, with associations to severity of AP. Substantial centre-level variations exist in the patterns of analgesic prescribing globally, contributing to variations in outcomes.

Background
Identifying biomarkers associated with pancreatic cancer (PC) development could facilitate early intervention and improve outcomes.
Methods
This study enrolled 206,363 participants, with 854 incident cases of PC were identified during follow-up. 168 metabolic biomarkers were measured by nuclear magnetic resonance spectroscopy, and the polygenic risk score (PRS) for PC constructed by 44 single nucleotide polymorphisms was calculated. Multivariate Cox regression analysis and multiple hypothesis testing were employed to evaluate the association between metabolites and PC risk. Stratified analyses and interaction tests were conducted to explore the effects of metabolites under different genetic backgrounds and lifestyle factors.
Results
After correction for multiple hypothesis testing, only plasma glycine levels showed a significant inverse correlation with PC risk (FDR-corrected P-value <0.05). High glycine levels were associated with a 21.4 % reduction in PC risk compared to low levels (HR: 0.786, 95 % CI: 0.657–0.940). PRS was positively associated with PC risk, with high PRS participants showing a 2.871-fold increased risk (95 % CI: 2.382–3.460). Glycine's protective effects were more pronounced in low PRS participants and never smokers. High glycine and low PRS participants demonstrated a 72.3 % reduction in PC risk compared to low glycine and high PRS participants (HR: 0.277, 95 % CI: 0.197–0.389). Notably, even among participants with the highest PRS, baseline plasma glycine levels were still significantly inversely associated with future PC risk.
Conclusion
Higher circulating glycine levels are associated with a reduced risk of PC, even in individuals with the highest genetic susceptibility. These findings suggest that higher circulating glycine levels may hold potential for PC prevention strategies, warranting further experimental validation of glycine supplementation in prospective trials.

Pancreatic adenosquamous carcinoma (PASC) is a highly rare and aggressive disease with poor prognosis. The median overall survival is less than one year. Aiming to identify the genomic characterization of the PASC, we conducted a retrospective analysis of the clinical characteristics and genomic alterations in 14 patients with PASC who underwent surgery at Beijing Hospital and Peking Union Medical College Hospital from 2010 to 2021. Genomic alterations were identified using targeted panel sequencing. We developed a PASC-specific signature to aid in the prognostic stratification of these patients. Our study revealed several genetic alterations potentially contributing to the development and progression of PASC, including TP53 mutations, MYC amplification, and CDKN2A deletion. Pathway enrichment analysis indicated that STK11 mutations, high tumor mutational burden (TMB-H), APC deletion, TERT/RICTOR amplification, and chromosomal instability (CIN-H) were significantly associated with altered pathways. Additionally, we confirmed the prognostic value of our PASC-specific signature through validation in an independent cohort of pancreatic ductal adenocarcinoma patients.

Background/objectives
Genetic mutations associated chronic pancreatitis (GCP), caused by pathogenic variants in SPINK1, PRSS1, or CFTR, represents a distinct subset of chronic pancreatitis, whereas alcoholic chronic pancreatitis (ACP) is the predominant adult etiology. We compared the clinical course and pancreatic cancer risk between GCP and ACP.
Methods
This retrospective cohort included GCP patients from a prospective registry with genetic testing (2009–2023) and ACP patients from a clinical database (1989–2023). Propensity score matching (1:3) balanced age, sex, BMI, smoking, diabetes, and Cambridge grade, yielding 139 GCP and 309 ACP patients. Outcomes were assessed using Kaplan–Meier and Cox regression, and cancer incidence was calculated per person-years with Poisson regression.
Results
In the matched GCP cohort, mutation distribution was SPINK1 67.6 % (94/139), PRSS1 15.8 % (22/139), and CFTR 11.5 % (16/139). Compared with ACP, GCP patients had more frequent pancreatic pain (89.2 % vs 77.3 %, p = 0.005) and a younger mean age at onset (26.5 vs 40.6 years, p < 0.001). New-onset diabetes was more common (35.3 % vs 21.7 %, p = 0.004) but developed later (22.5 vs 12.7 years, p < 0.001). Pancreatic atrophy occurred less often and later in GCP. Pancreatic cancer incidence was higher in GCP (4.24 vs 0.40 per 1000 person-years; IRR 10.61, p = 0.031), with all cancers arising within 5 years of diagnosis, predominantly in SPINK1 gene mutation carriers.
Conclusions
GCP shows distinct trajectories and an elevated early pancreatic cancer risk, particularly in SPINK1 gene mutation carriers, supporting genotype-stratified surveillance.
背景/目的:基因突变相关的慢性胰腺炎(GCP),由SPINK1、PRSS1或CFTR的致病变异引起,代表了慢性胰腺炎的一个独特的亚群,而酒精性慢性胰腺炎(ACP)是主要的成人病因。我们比较GCP和ACP的临床病程和胰腺癌风险。方法:该回顾性队列包括前瞻性基因检测登记的GCP患者(2009-2023)和临床数据库中的ACP患者(1989-2023)。倾向评分匹配(1:3)平衡了年龄、性别、BMI、吸烟、糖尿病和剑桥分级,得到139例GCP和309例ACP患者。使用Kaplan-Meier和Cox回归评估结果,使用泊松回归计算每个人年的癌症发病率。结果:在匹配的GCP队列中,突变分布为SPINK1 67.6% (94/139), PRSS1 15.8% (22/139), CFTR 11.5%(16/139)。与ACP相比,GCP患者胰腺疼痛更频繁(89.2% vs 77.3%, p = 0.005),平均发病年龄更年轻(26.5 vs 40.6岁,p < 0.001)。新发糖尿病更为常见(35.3%对21.7%,p = 0.004),但发病较晚(22.5年对12.7年,p < 0.001)。GCP患者胰腺萎缩发生率较低且较晚。GCP患者的胰腺癌发病率更高(4.24 vs 0.40 / 1000人-年;IRR 10.61, p = 0.031),所有癌症均在5年内发生,主要发生在SPINK1基因突变携带者中。结论:GCP表现出明显的轨迹和早期胰腺癌风险升高,特别是在SPINK1基因突变携带者中,支持基因型分层监测。

Background
Acute pancreatitis (AP) varies in severity, and traditional severity stratifications often fail to predict its early course. In people living with HIV (PLWH), chronic immune dysregulation leads to aberrant cytokine responses which influence biomarker performance. We hypothesize that in regions with high prevalence of HIV infection, HIV status will influence the immune biomarker performance in the prediction of severity of AP.
Methodology
In this prospective case-control study conducted in KwaZulu-Natal, 144 adult patients with AP (29 % PLWH) were enrolled. Blood samples were collected within 24 h of admission, and plasma was isolated and cryopreserved before cytokine levels were quantified using a multiplex electrochemiluminescence assay. Clinical severity was assessed using revised Atlanta classification. Receiver operating characteristic analyses were performed to derive optimal biomarker thresholds based on Youden's index, with significance set at p < 0.01.
Results
In people without HIV, IL-6, TNF-α, IL-15, IL-17, and MCP-1 were significantly upregulated in severe AP, with IL-15 demonstrating the highest discriminative performance (AUC 0.917; optimal cut-off 3.79 pg/mL; sensitivity 94.1 %, specificity 72.9 %). In PLWH patients, TNF-α was the only cytokine significantly associated with AP severity (AUC 0.974; optimal cut-off 9.42 pg/mL; sensitivity 100 %, specificity 97.4 %), while IL-17 did not predict severity in PLWH. Across the combined cohort, cytokine thresholds were higher in PLWH.
Conclusion
Distinct immune signatures correlate with AP severity and are significantly influenced by HIV status. IL-15 outperformed IL-6, TNF-α, IL-17, and MCP-1 in people without HIV, whereas TNF-α was the only predictor of severity in PLWH. Higher thresholds for prediction of severity in PLWH underscore the need for HIV-specific biomarker thresholds and further research into tailored severity stratification, and development of immunomodulating therapies in AP.

Background: Pancreaticoduodenectomy (PD) presents a surgical challenge, and its feasibility in patients on dialysis is debated due to concerns over heightened perioperative risks. This study employs the NSQIP pancreatectomy database to investigate the impact of dialysis on PD-specific postoperative complications.
Methods: The NSQIP pancreatectomy targeted user file spanning 2014 to 2023 was used to identify patients undergoing a PD. Patients on dialysis were matched 1:3 to patients not receiving dialysis. Comparative analysis evaluated morbidity, mortality, and PD-specific complications.
Results: Among 43,565 patients who underwent a PD, 123 patients were on dialysis. Even after matching, dialysis patients displayed higher rates of complications, re-intubation, cardiac arrest, and bleeding (p < 0.001); furthermore, 30-day mortality was higher in the dialysis group (8.1% vs 3.0%, p = 0.014). However, rates of clinically relevant postoperative pancreatic fistula, delayed gastric emptying, and indwelling drain on POD 30 did not differ.
Conclusions: Although dialysis patients undergoing PD face increased risks of mortality and complications, PD-specific complications were not affected. These findings offer valuable insights for patient counseling and surgeon awareness.
背景:胰十二指肠切除术(PD)提出了一个手术挑战,由于担心透析患者的围手术期风险增加,其可行性一直存在争议。本研究采用NSQIP胰腺切除术数据库,探讨透析对pd特异性术后并发症的影响。方法:2014年至2023年NSQIP胰腺切除术目标用户文件用于识别PD患者。接受透析的患者与未接受透析的患者的比例为1:3。比较分析评估了发病率、死亡率和pd特异性并发症。结果:在43,565例PD患者中,123例患者接受透析治疗。即使配对后,透析患者的并发症、再插管、心脏骤停和出血发生率也较高(p < 0.001);此外,透析组的30天死亡率更高(8.1% vs 3.0%, p = 0.014)。然而,临床相关的术后胰瘘、胃排空延迟和pod30留置引流的发生率没有差异。结论:虽然透析患者接受PD后死亡率和并发症的风险增加,但PD特异性并发症不受影响。这些发现为患者咨询和外科医生意识提供了有价值的见解。
