Elevated CA125 levels are associated with adverse clinical outcomes in acute pancreatitis: A propensity score-matched study.

OBJECTIVES: Glycosylation alterations are indicative of tissue inflammation and neoplasia. However, there are no large-sample, real-world studies assessing the levels of serum carbohydrate antigen 125 (CA125) in patients with acute pancreatitis (AP). We aimed to identify the association between elevated CA125 levels and adverse clinical outcomes in AP. METHODS: This was a retrospective cohort study with an analysis of 3939 patients with AP who were admitted to the First Affiliated Hospital of Nanchang University between January 2015 and September 2019 that used data from a prospectively maintained database. Multivariate logistic regression analysis and a propensity score-matched analysis were conducted to reveal the relationship between elevated CA125 levels and poor prognosis. RESULTS: The overall prevalence of elevated CA125 (>35 U/mL) levels was 38.51% (1517/3939) in AP patients. Elevated CA125 levels were independently associated with higher risks of mortality (adjusted odds ratio (AdjOR), 1.82; 95% confidence interval (CI), 1.30-2.54; P < 0.001), severe acute pancreatitis (SAP) (AdjOR, 2.40; 95% CI, 2.00-2.88; P < 0.001), and infected pancreatic necrosis (IPN) (AdjOR, 3.54; 95% CI, 2.65-4.71; P < 0.001). The propensity score-matched cohort analysis also demonstrated that mortality (OR, 1.57; 95% CI, 1.06-2.23; P < 0.05), SAP (OR, 2.20; 95% CI, 1.77-2.73; P < 0.001), and IPN (OR, 2.79; 95% CI, 1.98-3.92; P < 0.001) were more common in the elevated CA125 group than in the normal CA125 group. CONCLUSIONS: Elevated CA125 levels (>35 U/mL) are independently associated with adverse clinical outcomes in AP patients. These observations justify ongoing efforts to understand the role of CA125 in the pathogenesis and prognosis of AP.

New Risk Factors for Infected Pancreatic Necrosis Secondary to Severe Acute Pancreatitis: The Role of Initial Contrast-Enhanced Computed Tomography.

BACKGROUND AND AIMS: Pancreatic necrosis is a risk factor for poor prognosis of acute pancreatitis (AP). However, the associations between the findings on initial contrast-enhanced computed tomography (CT) of the pancreas and infected pancreatic necrosis (IPN) are unclear. METHODS: This was a retrospective cohort study. Patients with severe AP (SAP) from January 2014 to December 2016 at the First Affiliated Hospital of Nanchang University were enrolled and assigned to an IPN group and a non-IPN group. Univariate and multivariate logistic regression analyses were sequentially performed to assess the associations between the variables and IPN development. A receiver operating characteristic (ROC) curve was generated for the qualified independent risk factor. RESULTS: Forty-two patients with IPN were compared with 100 patients without IPN. Contrast-enhanced CT was performed 7 (range 3-10) days after AP onset. Multivariate stepwise logistic regression analyses showed that the number of acute peripancreatic fluid collections (APFCs) (OR 1.328, P = 0.006), presence of peripancreatic and pancreatic parenchymal necrosis (OR 4.001, P = 0.001), and gastrointestinal wall thickening (OR 3.353, P = 0.006) were independent risk factors for IPN secondary to SAP. The area under an ROC curve for the number of APFCs was 0.714, the sensitivity was 78.60%, and the specificity was 57.30% at a cutoff value of 4.5. CONCLUSIONS: The number of APFCs, presence of peripancreatic and pancreatic parenchymal necrosis, and gastrointestinal wall thickening were independent risk factors associated with IPN. As initial contrast-enhanced CT (about 7 days from AP onset) plays an important role in predicting IPN, it is important for clinicians to consider initial imaging of the pancreas.

Social Capital and Quality of Life Among People Living With HIV/AIDS in Southeast China.

A cross-sectional study was conducted with 261 people living with HIV (PLWH) in Southeast China. A social capital questionnaire was used to measure social capital dimensions (trust, social connection, and social participation). A Chinese version of the Medical Outcomes Study HIV Health Survey (MOS-HIV) was used to assess Quality of Life (QoL); Physical Health Summary Scores (PHS) and Mental Health Summary Scores (MHS) were calculated. Multiple regression assessed whether social capital and its dimensions were associated with PHS and MHS. After controlling for sociodemographics and HIV-related factors, lower PHS scores were found among participants with low overall social capital (P < .01) and low trust (P < .001). Lower MHS scores were found among participants with low overall social capital (P < .001), low trust (P < .001) and low social connection (P < .01). Our findings identify potential intervention targets to improve QoL among PLWH in Southeast China, including the promotion of social capital.
