Evaluating the prognostic performance of the novel ERAP score in Vietnamese acute pancreatitis patients.

Early recognition of severe acute pancreatitis (AP) is crucial for timely intervention. This study aims to evaluate the prognostic accuracy of the Emergency Room Assessment of AP (ERAP) score and compare it with the Bedside Index for Severity in AP (BISAP) score in predicting severe AP, mortality, and persistent multiple organ failure (MOF) in Vietnamese patients. This prospective cohort study included AP patients admitted to Cho Ray Hospital between August 2021 and May 2022. Patient data, including demographics, clinical presentations, and laboratory results, were collected upon admission. The ERAP and BISAP scores were calculated from these admission data. The prognostic accuracy for severe AP, mortality, and persistent MOF was assessed via the area under the receiver-operating characteristic curve (AUC). Among 167 AP patients (mean age 41.5 ±â€…12.0 years), hypertriglyceridemia (34.7%) and alcohol (22.2%) were the most prevalent etiologies. Severe AP accounted for 33.5% of the patients. Mortality rates were higher in persistent MOF patients (42.9%) than in persistent single-organ failure patients (3.6%), with a P value <.001. The ERAP score had AUCs for predicting severe AP, mortality, and persistent MOF of 0.899, 0.817, and 0.867, respectively, with an optimal cutoff of ≥2. The ERAP score had a better prognostic value than the BISAP score in predicting severe AP (AUC: 0.899 vs 0.820; P = .0072) and persistent MOF (AUC: 0.867 vs 0.785; P = .0193) but had a similar prognostic value for mortality (AUC: 0.817 vs 0.728; P = .0628). The ERAP score has strong predictive value for severe AP and persistent MOF, surpassing the BISAP score in these categories while maintaining similar accuracy for mortality prediction in the Vietnamese population. The ERAP score can be a valuable tool for the early identification of high-risk AP patients, enabling timely and appropriate clinical interventions.

Emodin alleviates lung injury via the miR-217-5p/Sirt1 axis in rats with severe acute pancreatitis.

Acute lung injury (ALI) is closely related to high mortality in severe acute pancreatitis (SAP). This study unveils the therapeutic effect and mechanism of miR-217-5p on SAP-associated ALI. The miR-217-5p RNA expression was significantly up-regulated in lipopolysaccharide (LPS)-stimulated primary rat alveolar epithelial type II cells (AEC II) and sodium taurocholate-treated pancreas and lung in SAP rats. miR-217 inhibition protected AEC II from LPS-induced damage by inhibiting apoptosis and reducing the TNF-α, IL-6, and ROS levels. miR-217 inhibition suppressed apoptosis and alleviated mitochondrial damage through mitochondria-mediated apoptotic pathway in vitro. Sirt1 is a direct target of miR-217-5p. Dual-luciferase reporter assay confirmed the binding of miR-217-5p to Sirt1 mRNA 3'-UTR. The rescue experiment identified that the anti-apoptotic, anti-inflammatory, and anti-oxidative effects of miR-217 inhibition were mediated by Sirt1 in vitro. Emodin (EMO) protected AEC II from LPS-induced damage and alleviated pancreatic and lung tissue injuries. EMO exerted similar effects as miR-217 inhibition in vitro and in vivo. The effects of EMO were abolished by miR-217 overexpression. In conclusion, miR-217-5p inhibition exerts protective effects on SAP-ALI in vitro and in vivo by repressing apoptosis, inflammation, and oxidative stress through Sirt1 activation. EMO protects against lung injuries in SAP-associated ALI rats through miR-217-5p/Sirt1 axis.

Effectiveness and safety of low molecular weight heparin in the management of acute pancreatitis: a systematic review and meta-analysis.

BACKGROUND: Recent studies suggest that low-molecular-weight heparin (LMWH) may play a role in mitigating the severity of acute pancreatitis (AP). This systematic review and meta-analysis aims to synthesise existing evidence on the effectiveness and safety of LMWH in the treatment of moderately-severe and severe AP. METHODS: This systematic review and meta-analysis was conducted in accordance with the 2020 update of the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The systematic search was conducted in MEDLINE, the Cochrane Central Register of Controlled Trials, Scopus, and EMBASE, covering studies published up to February 2024. Randomised controlled trials (RCTs) and observational studies (n-RCTs) that reported the differences in the outcomes of AP for patients receiving LMWH in addition to the standard treatment (Intervention), compared to patients managed by standard treatment without LMWH (Control) were eligible. A random-effects model was used to calculate the pooled relative risk (RR) and mean differences (MD) with the corresponding 95% CI. RESULTS: Thirteen studies were included in the meta-analysis, all published between 2004 and 2022. Eight studies were RCTs, and five were n-RCTs. Data from 13,709 patients (6.971 Interventions and 6.738 Controls) were analysed. The comparison of Intervention and Control groups showed the superiority of LMWH to standard treatments in terms of overall mortality (RR = 0.44, 95% CI = 0.31; 0.64, P < 0.0001, I2 = 51%), acute necrotic collections (RR = 0.24, 95% CI = 0.09; 0.62, P = 0.003, I2 = 0%), and organ failure (RR = 0.67, 95% CI = 0.48; 0.93, P = 0.02, I2 = 78%). The Intervention group showed superior outcomes compared with the Control group for gastrointestinal bleeding (RR = 0.64, 95% CI = 0.44; 0.94, P = 0.02, I2 = 0%), length of hospital stay (MD= - 6.08, 95% CI = - 10.08; - 2.07, P = 0.003, I2 = 98%), need for operative interventions (RR = 0.50, 95% CI = 0.29; 0.87, P = 0.01, I2 = 61%), and vascular thrombosis (RR = 0.43, 95% CI = 0.31; 0.61, P < 0.00001, I2 = 0%). CONCLUSIONS: Moderate to high-quality evidence suggests that early intervention with LMWH could improve the prognosis of non-mild AP in terms of mortality, organ failure, and decreased incidence of vascular thrombosis. In light of our findings, integrating LMWH into the treatment regimen for moderate-severe to severe AP is advocated.

Chaiqin chengqi decoction treatment mitigates hypertriglyceridemia-associated acute pancreatitis by modulating liver-mediated glycerophospholipid metabolism.

BACKGROUND: The incidence of hypertriglyceridemia-associated acute pancreatitis (HTG-AP) is increasing globally and more so in China. The characteristics of liver-mediated metabolites and related key enzymes are rarely reported in HTG-AP. Chaiqin chengqi decoction (CQCQD) has been shown to protect against AP including HTG-AP in both patients and rodent models, but the underlying mechanisms in HTG-AP remain unexplored. PURPOSE: To assess the characteristics of liver-mediated metabolism and the therapeutic mechanisms of CQCQD in HTG-AP. METHODS: Male human apolipoprotein C3 transgenic (hApoC3-Tg; leading to HTG) mice or wild-type littermates received 7 intraperitoneal injections of cerulein (100 µg/kg) to establish HTG-AP and CER-AP, respectively. In HTG-AP, some mice received CQCQD (5.5 g/kg) gavage at 1, 5 or 9 h after disease induction. AP severity and related liver injury were determined by serological and histological parameters; and underlying mechanisms were identified by lipidomics and molecular biology. Molecular docking was used to identify key interactions between CQCQD compounds and metabolic enzymes, and subsequently validated in vitro in hepatocytes. RESULTS: HTG-AP was associated with increased disease severity indices including augmented liver injury compared to CER-AP. CQCQD treatment reduced severity and liver injury of HTG-AP. Glycerophospholipid (GPL) metabolism was the most disturbed pathway in HTG-AP in comparison to HTG alone. In HTG-AP, the mRNA level of GPL enzymes involved in phosphocholine (PC) and phosphatidylethanolamine (PE) synthesis (Pcyt1a, Pcyt2, Pemt, and Lpcat) were markedly upregulated in the liver. Of the GPL metabolites, lysophosphatidylethanolamine LPE(16:0) in serum of HTG-AP was significantly elevated and positively correlated with the pancreas histopathology score (r = 0.65). In vitro, supernatant from Pcyt2-overexpressing hepatocytes co-incubated with LPE(16:0) or phospholipase A2 (a PC- and PE-hydrolyzing enzyme) alone induced pancreatic acinar cell death. CQCQD treatment downregulated PCYT1a and PCYT2 enzyme levels in the liver. Hesperidin and narirutin were identified top two CQCQD compounds with highest affinity docking to PCYT1a and PCYT2. Both hesperidin and narirutin reduced the level of some GPL metabolites in hepatocytes. CONCLUSION: Liver-mediated GPL metabolism is excessively activated in HTG-AP with serum LPE(16:0) level correlating with disease severity. CQCQD reduces HTG-AP severity partially via modulating key enzymes in GPL metabolism pathway.

Association between triglyceride glucose-body mass index and all-cause mortality in critically ill patients with acute pancreatitis.

This study delves into the correlation between the triglyceride glucose-body mass index (TyG-BMI) index upon hospital admission and clinical outcomes among this patient population. We investigated the association between TyG-BMI at hospital admission and clinical outcomes in this patient group, and analyzed data from the Medical Information Mart for Intensive Care IV database, identifying acute pancreatitis (AP) patients admitted to ICUs and stratifying them by TyG-BMI quartiles. We assessed the relationship between TyG-BMI and mortality (both in-hospital and ICU) using Cox proportional hazards regression and restricted cubic splines. The cohort included 419 patients, average age 56.34 ± 16.62 years, with a majority being male (61.58%). Hospital and ICU mortality rates were 11.93% and 7.16%, respectively. Higher TyG-BMI was positively correlated with increased all-cause mortality. Patients in the highest TyG-BMI quartile had significantly greater risks of in-hospital and ICU mortality. An S-shaped curve in the spline analysis indicated a threshold effect at a TyG-BMI of 243 for increased in-hospital mortality risk. TyG-BMI is a reliable predictor of both in-hospital and ICU mortality in severely ill AP patients, suggesting its utility in enhancing risk assessment and guiding clinical interventions for this vulnerable population.

Network pharmacological mechanism analysis and evidence-based medical validation of Dahuang Mudan Decoction in the treatment of acute pancreatitis.

BACKGROUND: Dahuang Mudan Decoction is commonly used in China for the treatment of acute pancreatitis. Nevertheless, the therapeutic efficacy of the drug remains a subject of debate, and its active ingredients and potential therapeutic targets remain to be determined. The present study used a network pharmacological approach to investigate the active ingredients and possible targets of the drug, and illustrated the clinical effectiveness of Dahuang Mudan Decoction in the treatment of acute pancreatitis by meta-analysis. METHODS: The present study investigated the active ingredients of the constituent herbs of Dahuang Mudan Decoction using the TCMID database. In order to further identify molecular targets, Swiss Target Prediction, OMIM and Genecards databases was be used. The present study used metascape database for gene ontology function enrichment analysis and Kyoto Genome Encyclopedia pathway enrichment analysis. A gene interaction network diagram was established for predicting the main targets and mechanism of action to Dahuang Mudan Decoction for acute pancreatitis. To further illustrate the validity of the gene targets and the clinical efficacy of the drug, 13 relevant studies were included for meta-analysis and analyzed using the Cochrane Collaboration's Review Manager 5.4 software. RESULT: After a thorough screening process, the present study identified three main components of Dahuang Mudan Decoction: kaempferol, quercetin and eupatin. These three major components have the potential to target 5 important proteins: AKT1, TNF-a, IL-6, TP53, HIF1A. In addition, pathway analyses by the Kyoto Genome Encyclopedia showed that Dahuang Mudan Decoction is active through the Pathways in cancer, AGE-RAGE signaling pathway in diabetic complications, PI3K-Akt signaling pathway, etc signaling pathway to act on acute pancreatitis. The results of meta-analysis showed that compared with the control group, the experimental group had superior performance in terms of overall treatment efficacy, reduction of hospital stays and inflammatory factor levels after treatment. CONCLUSION: In summary, network pharmacological studies have shown that Dahuang Mudan Decoction affects acute pancreatitis through different components, targets, and mechanisms. In addition, the meta-analysis study strongly supported the effectiveness of Dahuang Mudan Decoction in the treatment of acute pancreatitis.

Choledochal Cyst and Pancreas Divisum: A Case Report.

BACKGROUND A choledochal cyst (CC), or biliary cyst, is a congenital or acquired anomaly of the biliary tree. Pancreas divisum (PD) is a rare congenital anomaly due to incomplete fusion of pancreatic ducts, which can complicate the clinical course of choledochal cysts. This rare combination is a surgical management challenge. This report presents the diagnosis and management of a 23-year-old woman with a combined choledochal cyst and pancreas divisum treated with pancreaticoduodenectomy. CASE REPORT This article presents the case of a 23-year-old woman who presented with severe, stabbing abdominal pain radiating to the back and epigastric tenderness and was diagnosed with pancreatitis. Initial imaging revealed a choledochal cyst, prompting further investigation with ERCP that showed concomitant PD. She was treated via pancreaticoduodenectomy. During the following 9 years, she was hospitalized over 2 dozen times for recurrent pancreatitis. CONCLUSIONS This report presents a complex case of a combined choledochal cyst and pancreas divisum, which was surgically managed by pancreaticoduodenectomy. The association of CC with PD should be suspected in patients with recurrent acute pancreatitis and/or cholangitis with no identifiable cause. Surgical treatment of CC with PD depends on the classification of the CC, and complications can include recurrent pancreatitis, though prognosis is often favorable. The purpose of this manuscript is to emphasize that pancreaticoduodenectomy is unlikely to provide favorable outcomes for CC with PD, especially considering there is evidence that less extensive surgical interventions produce better outcomes.

Effect of whole-process high-quality nursing on the quality of life of acute pancreatitis patients and the mechanism of miR-126-5p/HOXC8 axis promoting the progression of acute pancreatitis.

The current research was designed to investigate the impact of whole-process high-quality nursing on acute pancreatitis (AP) patients' quality of life as well as the mechanism of miR-126-5p/HOXC8 axis promoting AP progression. One hundred AP patients admitted to our hospital were chosen and separated into control group (CG, n=50) and study group (SG, n=50). The CG took the routine nursing, while the SG adopted the whole-process high-quality nursing. Besides, cerulein (CE) was treated in AR42J cells to establish an experimental model of AP. The proliferation, apoptosis along with inflammation of CE-treated AR42J cells were assessed. The outcomes manifested that in contrast to the CG, the recovery time of bowel sound, the improvement time of abdominal distension, the improvement time of abdominal pain, the exhaust time and the defecation time in the SG presented shorter, the anxiety and depression scores in the SG presented lower, the WHOQOL-100 scores of patients in the SG presented higher in the fields of physiology, psychology, environment and social relations, the total incidence of complications of the SG presented lower, and the total nursing satisfaction of the SG was better. Besides, miR-126-5p presented upregulation in CE-stimulated AR42J cells, and miR-126-5p inhibition increased the proliferation along with repressed the apoptosis and inflammation in CE-stimulated AR42J cells. Moreover, HOXC8 could be the target mRNA of miR-126-5p, and HOXC8 elevation promoted the proliferation along with repressed the apoptosis and inflammation in CE-stimulated AR42J cells. In addition, rescue assays further validated that HOXC8 silence offset the protective impact of miR-126-5p repression on AP cell damage. In conclusion, our study indicated that whole-process high-quality nursing could promote the quality of life of AP patients, and revealed that miR-126-5p inhibition relieved CE-stimulated AR42J cells injury caused by AP via targeting HOXC8. Our study might offer novel insights for AP treatment and nursing.

Doxycycline-associated acute pancreatitis: a rare adverse effect of a commonly prescribed antibiotic.

In this case, a woman in her 80s presented to the emergency department with signs and symptoms of acute pancreatitis that began after starting a course of doxycycline. Common aetiologies of acute pancreatitis, including alcohol use, gallstones and hypertriglyceridaemia were ruled out. Less common aetiologies, including recent Endoscopic Retrograde Cholangiopancreatography (ERCP) procedure, hypercalcaemia, malignancy, infection and trauma, were also ruled out, making drug-induced acute pancreatitis the most likely aetiology. After consideration of her medication list, doxycycline was determined to be the offending medication. On discontinuation and treatment with fluids and analgesics, her condition slowly improved.This case illustrates a rare but severe complication of doxycycline use. Determining the aetiology of drug-induced acute pancreatitis is more difficult in older patients due to high rates of polypharmacy. Recognition of doxycycline as an aetiology of drug-induced pancreatitis may allow earlier recognition and intervention in cases of suspected pancreatitis without a clear common aetiology in older patients with polypharmacy.

Diagnostic Value of Serum Amylase and Coagulation Function Indices in Distinguishing Acute Pancreatitis from Aortic Dissection.

BACKGROUND: Due to similar symptoms of abdominal pain, acute pancreatitis (AP) is often difficult to differentiate from acute aortic dissection (AAD) in clinical practice. It is unknown whether serum amylase and coagulation function indices can be used to distinguish AP from AAD. METHODS: In this retrospective study, 114 AP patients (AP group) and 48 cases with AAD (AAD group) admitted for acute abdominal pain were enrolled for a final analysis. The levels of serum amylase and coagulation function indices, including prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (APTT), fibrinogen (FIB), and D-dimer (DD), were tested before or on admission and compared between the two groups. Student's t-test was adopted for comparing the mean. Model discrimination was evaluated by using the area under the receiver operating characteristic curve (AUC). Comparison of AUC was performed by using the Z-test. RESULTS: Compared with the AAD group, amylase and FIB were both significantly increased, while DD was significantly lower in the AP group (all p < 0.01). There were no statistically significant differences of PT, INR, and APTT between AP and AAD (all p > 0.05). The AUCs in distinguishing AP from AAD were 0.913, 0.854, and 0.837 for amylase, FIB, and DD, respectively, but there were no significant differences observed among amylase, FIB, and DD (all p > 0.05). Finally, the cutoff values (specificity, sensitivity, and Youden index) in distinguishing between AP and AAD were 114 µ/L (80.70%, 95.83%, 0.765) for amylase, 2.62 g/L (76.32%, 85.42%, 0.617) for FIB, and 2.74 mg/L (95.61%, 62.50%, 0.581) for DD, respectively. CONCLUSIONS: Amylase, FIB, and DD can demonstrate accurate and reliable diagnostic values, suggesting that they are useful and potential biomarkers in distinguishing AP from AAD.

Involvement of heparanase in the pathogenesis of acute pancreatitis: Implication of novel therapeutic approaches.

Acute pancreatitis (AP) is a common gastrointestinal disease with high morbidity and mortality rate. Unfortunately, neither the etiology nor the pathophysiology of AP are fully understood and causal treatment options are not available. Recently we demonstrated that heparanase (Hpa) is adversely involved in the pathogenesis of AP and inhibition of this enzyme ameliorates the manifestation of the disease. Moreover, a pioneer study demonstrated that Aspirin has partial inhibitory effect on Hpa. Another compound, which possesses a mild pancreato-protective effect against AP, is Trehalose, a common disaccharide. We hypothesized that combination of Aspirin, Trehalose, PG545 (Pixatimod) and SST0001 (Roneparstat), specific inhibitors of Hpa, may exert pancreato-protective effect better than each drug alone. Thus, the current study examines the pancreato-protective effects of Aspirin, Trehalose, PG545 and SST0001 in experimental model of AP induced by cerulein in wild-type (WT) and Hpa over-expressing (Hpa-Tg) mice. Cerulein-induced AP in WT mice was associated with significant rises in the serum levels of lipase (X4) and amylase (X3) with enhancement of pancreatic edema index, inflammatory response, and autophagy. Responses to cerulein were all more profound in Hpa-Tg mice versus WT mice, evident by X7 and X5 folds increase in lipase and amylase levels, respectively. Treatment with Aspirin or Trehalose alone and even more so in combination with PG545 or SST0001 were highly effective, restoring the serum level of lipase back to the basal level. Importantly, a novel newly synthesized compound termed Aspirlose effectively ameliorated the pathogenesis of AP as a single agent. Collectively, the results strongly indicate that targeting Hpa by using anti-Hpa drug combinations constitute a novel therapy for this common orphan disease.

The causality between use of glucocorticoids and risk of pancreatitis: a Mendelian randomization study.

Background and aim: To date, the association between glucocorticoid use and the risk of pancreatitis remains controversial. The aim of this study was the investigation of this possible relationship. Methods: We carried out a two-sample Mendelian randomization (MR) analysis using GWAS data from European ancestry, East Asian descendants and the FinnGen Biobank Consortium to evaluate this potential causal relationship. Genetic variants associated with glucocorticoid use were selected based on genome-wide significance (p < 5×10-8). Results: Our MR analysis of European ancestry data revealed no significant causal relationship between glucocorticoid use and AP (IVW: OR=1.084, 95% CI= 0.945-1.242, P=0.249; MR-Egger: OR=1.049, 95% CI= 0.686-1.603, P=0.828; weighted median: OR=1.026, 95% CI= 0.863-1.219, P=0.775) or CP (IVW: OR=1.027, 95% CI= 0.850-1.240, P=0.785; MR-Egger: OR= 1.625, 95% CI= 0.913-2.890, P= 0.111; weighted median: OR= 1.176, 95% CI= 0.909-1.523, P= 0.218). Sensitivity analyses, including MR-Egger and MR-PRESSO, indicated no evidence of pleiotropy or heterogeneity, confirming the robustness of our findings. Multivariable MR analysis adjusted for alcohol consumption, BMI, cholelithiasis and C-reactive protein levels supported these findings. Replicated analysis was performed on datasets from the FinnGen Biobank Consortium and East Asian descendants, and similar results were obtained. Conclusions: This MR analysis suggests that there is no causal association between glucocorticoid use and the risk of pancreatitis.

Integrating metagenomics with metabolomics for gut microbiota and metabolites profiling in acute pancreatitis.

Acute pancreatitis (AP) is an inflammatory disease of the pancreas. Despite of a steadily increasing in morbidity and mortality, there is still no effective therapy. Gut microbial dysbiosis and its derived-metabolites disorder have been shown to play an important role in the development of AP, however, little is known regarding the crosstalk between gut microbiota and metabolites. In this study, we assessed the alterations in gut microbiota and metabolites by constructing three AP mouse models by means of metagenomic and metabolomic sequencing, and further clarified their relationship by correlation analysis. The results revealed that each model exhibited unique flora and metabolite profiles. KEGG analysis showed that the differential flora and metabolite-enriched pathway functions were correlated with lipid metabolism and amino acid metabolism. Moreover, two core differential bacterial species on Burkholderiales bacterium YL45 and Bifidobacterium pseudolongum along with eleven differential metabolites appeared to exert certain effects during the course of AP. In conclusion, further exploration of the crosstalk between microbiota and derived metabolites may provide novel insights and strategies into the diagnosis and treatment of AP.

m6A-activated BACH1 exacerbates ferroptosis by epigenetic suppression HSPB1 in severe acute pancreatitis.

Severe acute pancreatitis (SAP) is characterized by acute inflammation of the pancreas. The transcription factor BTB and CNC homology 1 (BACH1) has been implicated in various biological processes, including oxidative stress, apoptosis, and cell cycle regulation. However, its involvement in the pathogenesis of SAP remains relatively understudied. In the present work, our data demonstrated that BACH1 level was significantly increased in SAP patients, cellular, and animal models, while heat shock protein B1 (HSPB1) expression was weakened. Mechanistic assays validated that BACH1 acted as a transcriptional inhibitor of HSPB1. Moreover, HPDE6-C7 cells were stimulated with cerulein (Cer) and LPS to mimic the pathological stages of SAP in vitro. Depletion of BACH1 remarkably improved cell survival and alleviated the oxidative stress, ferroptosis, and inflammatory responses in SAP cell models. However, these changes were dramatically reversed upon co-inhibition of HSPB1. Animal findings confirmed that loss of BACH1 decreased pancreatic injury, inflammatory responses, and ferroptosis, but these effects were weakened by HSPB1 silence. Overall, these findings elucidate that the overexpression of BACH1 favors the ferroptosis and inflammation by transcriptionally inhibiting HSBP1, thereby exacerbating SAP progression.

Molecular mechanism and potential role of mitophagy in acute pancreatitis.

Acute pancreatitis (AP) is a multifaceted inflammatory disorder stemming from the aberrant activation of trypsin within the pancreas. Despite the contribution of various factors to the pathogenesis of AP, such as trypsin activation, dysregulated increases in cytosolic Ca2+ levels, inflammatory cascade activation, and mitochondrial dysfunction, the precise molecular mechanisms underlying the disease are still not fully understood. Mitophagy, a cellular process that preserves mitochondrial homeostasis under stress, has emerged as a pivotal player in the context of AP. Research suggests that augmenting mitophagy can mitigate pancreatic injury by clearing away malfunctioning mitochondria. Elucidating the role of mitophagy in AP may pave the way for novel therapeutic strategies. This review article aims to synthesize the current research findings on mitophagy in AP and underscore its significance in the clinical management of the disorder.

Rare skin color changes in an acute pancreatitis patient undergoing maintenance hemodialysis.

BACKGROUND: Skin conditions are common in patients on maintenance hemodialysis and those with pancreatitis. However, there is a lack of research on dermatological issues in patients who have both hemodialysis and pancreatitis concurrently. CASE PRESENTATION: A 62-year-old male patient with a 4-year history of maintenance hemodialysis (MHD) presented with pain and was diagnosed with acute pancreatitis and gallbladder stones. Markedly elevated blood amylase, creatine kinase, and myoglobin were noted, alongside a purplish-red skin discoloration. Treatment included inhibition of digestive fluid secretion, anti-infection measures, blood purification, fasting, rehydration, and symptomatic care. Notably, continuous renal replacement therapy (CRRT) combined with hemoperfusion (HP) was employed. The patient's dialysis effluent initially appeared red. Upon examination of the patient's peripheral blood smear, red blood cell debris was not observed. The dialysis effluent (on Day 0) was analyzed, revealing no hemoglobin (0 g/L) but an elevated myoglobin concentration of 80.4 U/L. After the therapeutic intervention, the indicators, including the blood amylase, C-reactive protein, total bilirubin, creatine kinase, and myoglobin were improved. The patient experienced resolution of sternal and upper abdominal pain within two days. After four consecutive days of CRRT and HP treatment, the skin color returned to normal, alongside improved clarity of the dialysis effluent. Subsequently, the patient's method of blood purification was reverted to conventional hemodialysis. On the eighth day of hospitalization, the patient resumed normal diet and was discharged. CONCLUSIONS: In the case of the current patient with acute pancreatitis undergoing MHD, it is noteworthy to report the observation of a unique purplish-red skin discoloration. This phenomenon may be attributable to inflammation resulting from acute pancreatitis, and the retention of myoglobin within the body.

Quantification of muscle recovery in post-ICU patients admitted for acute pancreatitis: a longitudinal single-center study.

OBJECTIVES: Critically ill patients with severe pancreatitis exhibit substantial muscle wasting, which limits in-hospital and post-hospital outcomes. Survivors of critical illness undergo extensive recovery processes. Previous studies have explored pancreatic function, quality of life, and costs post-hospitalization for AP patients, but none have comprehensively quantified muscle loss and recovery post-discharge. By applying an AI-based automated segmentation tool, we aimed to quantify muscle mass recovery in ICU patients after discharge. MATERIALS: Muscle segmentation was performed on 22 patients, with a minimum of three measurements taken during hospitalization and one clinically indicated examination after hospital discharge. Changes in psoas muscle area (PMA) between admission, discharge and follow up were calculated. T-Test was performed to identify significant differences between patients able and not able to recover their muscle mass. RESULTS: Monitoring PMA shows muscle loss during and gain after hospitalization: The mean PMA at the first scan before or at ICU admission (TP1) was 17.08 cm², at the last scan before discharge (TP2), mean PMA was 9.61 cm². The percentage change in PMA between TP1 and TP2 ranged from - 85.42% to -2.89%, with a mean change of -40.18%. The maximum muscle decay observed during the stay was - 50.61%. After a mean follow-up period of 438.73 days most patients (81%) were able to increase their muscle mass. Compared to muscle status at TP1, only 27% of patients exhibited full recovery, with the majority still presenting a deficit of 31.96%. CONCLUSION: Muscle recovery in ICU patients suffering from severe AP is highly variable, with only about one third of patients recovering to their initial physical status. Opportunistic screening of post-ICU patient recovery using clinically indicated imaging and AI-based segmentation tools enables precise quantification of patients' muscle status and can be employed to identify individuals who fail to recover and would benefit from secondary rehabilitation. Understanding the dynamics of muscle atrophy may improve prognosis and support personalized patient care.

Effects of toll like receptor 4 (TLR4) and toll like receptor 2 (TLR 2) gene polymorphisms on clinical outcomes in acute non-biliary pancreatitis patients.

Introduction: In this retrospective study, it was aimed to evaluate effects of Toll Like Receptor 4 (TLR4) and Toll Like Receptor 2 (TLR 2) gene polymorphisms on clinical outcomes in acute non-biliary pancreatitis patients. Methods: A total of 108 acute non-biliary pancreatitis patients (ANBP) were retrospectively subjected to the study. Gender, age, number of attacks, hospitalization duration, amylase, lipase, aspartate aminotransferase (AST), alanine aminotransferase (ALT), leukocyte, C-reactive protein (CRP), total bilirubin, direct bilirubin, Atlanta score, ultrasonography (USG), Computer Tomography (CT) and patient outcome differences between TLR 4 Rs4986790, TLR 4 Rs4986791 and TLR 2 groups were evaluated. Results: According to TLR 4 Rs4986790 groups, females were significantly common in AA sequence (AA) group with statistically significant difference (p<0.05). Leukocyte mean of AG sequence (AG) group was significantly higher than of AA group (p<0.05). All parameter differences between TLR 4 Rs4986791 and TLR 2 groups were statistically insignificant (p>0.05). there was a statistically significant correlation between TLR 4 Rs4986790 and gender (r=0.265; p<0.01), Leukocyte (r=0.200; p<0.05) and Pseudocyst (r=0.203; p<0.05). TLR 4 Rs4986790 gene polymorphism had significant effect on leukocyte level in acute non-biliary pancreatitis patients (OR: -0.1.900; p<0.05). Predictive value of leukocyte for TLR 4 Rs4986790 was statistically significant (Area Under Curve: 0.624; p<0.05). For 7.65 leukocyte cut off value, sensitivity for AA gene polymorphism was 84.2% and specificity was 40.5. Conclusion: Although the clinical and outcome parameters of ANBP patients in terms of TLR 4 Rs4986791 and TLR 2 do not show significant differences, research findings point to the diagnostic value of patients' leukocyte parameters in determining TLR-4 Rs4986790 ploimorphism groups.
