Acute pancreatitis: mechanisms and therapeutic approaches
Acute pancreatitis is a complex inflammatory condition characterized by sudden onset and rapid progression, with severe cases often associated with high mortality. In recent years, the global incidence of acute pancreatitis has been increasing, with marked regional differences. This increasing trend not only places a considerable burden on healthcare systems but also significantly affects the physical and psychological well-being of patients. The most common causes-gallstone disease, hypertriglyceridemia, and alcohol abuse-also vary by region. This review provides a structured summary of current knowledge regarding the definition and classification of acute pancreatitis, along with recent advances in clinical scoring systems, biomarkers, and predictive models based on artificial intelligence. These tools are particularly valuable for risk stratification and early clinical decision-making. In addition, this review discusses the multilevel pathophysiological mechanisms involved in acute pancreatitis, including aberrant enzymatic activation, calcium overload, impaired autophagy, inflammatory responses, and various forms of pancreatic acinar cell death. From a therapeutic perspective, both early-phase management and strategies for later disease stages are addressed. This review also briefly assesses adjunctive therapies rooted in traditional Chinese medicine, including bioactive monomers, compound herbal formulas, and external treatment modalities. Furthermore, attention is given to individualized treatment approaches for special populations, as well as to emerging therapeutic avenues such as nanotechnology and extracellular vesicle-based interventions. Together, these insights serve as a comprehensive reference for the diagnosis and management of acute pancreatitis while also suggesting potential directions for future research and innovation.

Etiology & Epidemiology Insights
Acute pancreatitis incidence is rising globally, driven by improved diagnostic criteria and shifts in risk factors. Regional heterogeneity is significant, with varying primary causes like gallstones, hypertriglyceridemia, and alcohol abuse. Special populations, such as children and pregnant women, exhibit distinct etiological profiles.
Pathophysiological Mechanisms Insights
AP is driven by premature activation of pancreatic enzymes, calcium overload, impaired autophagy, and inflammatory responses. Specific mechanisms include lysosomal cathepsin dysfunction (CTSB, CTSL, CTSD, CTSC), ER and mitochondrial calcium signaling disruptions, ER stress, and multi-organ crosstalk. These processes contribute to acinar cell death (apoptosis, necrosis, necroptosis, pyroptosis, ferroptosis) and systemic inflammation.
Diagnosis & Prediction Insights
Diagnosis relies on characteristic abdominal pain, elevated serum lipase/amylase, and imaging findings. Clinical scoring systems (e.g., Ranson, APACHE II, BISAP, SIRS) and novel biomarkers (e.g., BUN, CRP, IL-6, TNF-α) aid severity assessment. AI/ML models, especially ensemble and deep learning methods, show promise in improving predictive accuracy for outcomes like organ failure and mortality, surpassing traditional tools.
Therapeutic Strategies Insights
Treatment involves early fluid resuscitation (lactated Ringer's preferred), pain management (stepwise analgesia), and nutritional support (early enteral nutrition). Etiological management targets specific causes (cholecystectomy for biliary AP, abstinence for alcoholic AP, plasmapheresis/insulin for HTG-AP). Surgical interventions are reserved for complications, with a step-up approach favoring minimally invasive techniques for infected necrosis.
Future Directions Insights
Future research focuses on personalized medicine, dynamic prediction models, multi-omics integration, and AI-driven decision support. Emerging therapies like nanotechnology-based drug delivery and extracellular vesicle-based interventions offer precision targeting and reduced systemic toxicity. Traditional Chinese Medicine (TCM) provides adjunctive benefits for anti-inflammation and organ protection.

Case Study: AI for Early SAP Prediction
A multi-task gated recurrent unit (MT-GRU) deep learning model was applied to a large Chinese cohort (n=13,645) for real-time prediction of organ failure in acute pancreatitis. The model achieved AUROCs of 0.910 for respiratory failure, 0.890 for circulatory failure, and 0.700 for acute kidney injury. This demonstrates the value of sequential modeling for dynamic clinical decision support, highlighting the potential of AI to identify patients at high risk of severe AP much earlier than traditional methods.

92.1% AUROC for XGBoost Model Predicting SAP requiring ICU AdmissionCase Study: Nanotechnology for Targeted Drug Delivery
Nanocarriers and nanodrugs, due to their small particle size and high specific surface area, can penetrate inflamed pancreatic tissue, overcome biological barriers, and achieve targeted delivery. For instance, thioketone-modified liposomal nanocarriers (DTM@KA NPs) significantly increased kaempferol bioavailability and alleviated pancreatic inflammation by promoting STAT6-mediated mitochondrial protein transport and Pink1/Parkin-regulated autophagy. Macrophage membrane-coated nanodelivery systems have also shown improved therapeutic efficacy for emodin, reducing serum α-amylase and lipase levels. This illustrates the potential of nanotechnology to enhance drug safety and optimize therapeutic outcomes by ensuring precise delivery to the affected sites.

Your AI Implementation Roadmap
A structured approach to integrating AI into your enterprise, ensuring a smooth transition and measurable impact.
Phase 01: Pre-analysis & Diagnostic Screening
Initial assessment of AP risk factors (gallstones, HTG, alcohol), diagnostic criteria application (RAC 2012), and severity grading (Ranson, APACHE II, BISAP, SIRS, CTSI). Utilize current biomarkers (BUN, CRP, IL-6, TNF-α) and AI-based predictive models for early risk stratification and prognosis.
Phase 02: Acute Management & Early Intervention
Initiate early fluid resuscitation with lactated Ringer's solution, guided by individualized, goal-directed protocols to optimize perfusion and avoid fluid overload. Implement stepwise pain management, starting with non-opioids. Begin early enteral nutrition within 24-72 hours, preferring oral or nasoenteral routes. Target underlying causes like acute cholangitis with ERCP, if indicated.
Phase 03: Pathophysiological Modulation & Adjunctive Therapies
Consider adjunctive therapies targeting key pathological mechanisms: cathepsin inhibitors, calcium channel blockers, autophagy modulators (mTOR inhibitors, trehalose), and anti-inflammatory agents (IL-6/TNF-α antagonists). Explore TCM-based interventions (bioactive monomers, compound herbal formulas, external treatments) as complementary strategies for anti-inflammation and organ protection.
Phase 04: Management of Complications & Later Stages
For necrotizing pancreatitis, follow a step-up approach, delaying intervention to allow necrosis to demarcate. Implement percutaneous catheter drainage (PCD) for liquefied collections. Consider endoscopic necrosectomy for walled-off necrosis (WON) or pancreatic pseudocysts adjacent to the GI tract. Surgical necrosectomy for extensive or infected necrosis with multi-organ failure. Address special populations (pregnancy, pediatric) with individualized protocols.
Phase 05: Long-term Recovery & Prevention
Monitor patients for long-term complications (diabetes, chronic pancreatitis). Implement lifestyle modifications and pharmacological agents for HTG-AP. Integrate emerging therapies like nanotechnology for targeted drug delivery and extracellular vesicles for tissue regeneration. Establish a comprehensive AP registry for continuous follow-up and refined classification.
