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.

Pancreatic necrosis and severity are independent risk factors for pancreatic endocrine insufficiency after acute pancreatitis: A long-term follow-up study.

BACKGROUND: Pancreatic endocrine insufficiency after acute pancreatitis (AP) has drawn increasing attention in recent years. AIM: To assess the impact of risk factors on the development of pancreatic endocrine insufficiency after AP. METHODS: This retrospective observational long-term follow-up study was conducted in a tertiary hospital. Endocrine function was evaluated by the oral glucose tolerance test. The data, including age, sex, body mass index, APACHE II score, history of smoking and drinking, organ failure, pancreatic necrosis, debridement of necrosis (minimally invasive and/or open surgery), and time interval, were collected from the record database. RESULTS: A total of 361 patients were included in the study from January 1, 2012 to December 30, 2018. A total of 150 (41.6%) patients were diagnosed with dysglycemia (including diabetes mellitus and impaired glucose tolerance), while 211 (58.4%) patients had normal endocrine function. The time intervals (mo) of the above two groups were 18.73 ± 19.10 mo and 31.53 ± 27.27 mo, respectively (P = 0.001). The morbidity rates of pancreatic endocrine insufficiency were 46.7%, 28.0%, and 25.3%, respectively, in the groups with different follow-up times. The risk factors for pancreatic endocrine insufficiency after AP were severity (odds ratio [OR] = 3.489; 95% confidence interval [CI]: 1.501-8.111; P = 0.004) and pancreatic necrosis (OR = 4.152; 95%CI: 2.580-6.684; P = 0.001). CONCLUSION: Pancreatic necrosis and severity are independent risk factors for pancreatic endocrine insufficiency after AP. The area of pancreatic necrosis can affect pancreatic endocrine function.

Blue laser magnifying endoscopy in the diagnosis of chronic gastritis.

The current study aimed to evaluate the clinical value of using blue laser imaging combined with magnifying endoscopy in the diagnosis of chronic gastritis (CG). The groups used were as follows: The white light group (WLI, control group), linked color imaging group (LCI, observation group 1), blue laser imaging (BLI)-bright (brt) group (BLI-brt; observation group 2), BLI + magnified imaging (ME) group (observation group 3). WLI mode initially allowed the observation of mucosal suspicious lesions on the gastric mucosa. These lesions were photographed and the mode was changed to LCI, BLI-brt and BLI + ME. Different observational patterns were compared between modes to diagnose various grades of chronic gastritis. No significant differences were observed in the baseline information of enrolled patients. The LCI mode diagnosis rate was higher for Helicobacter pylori (HP) infection than in any other mode. LCI exhibited a high diagnostic rate for HP, BLI-brt exhibited a high diagnostic rate for atrophy and BLI/BLI + ME exhibited a high diagnostic rate for intestinal metaplasia and intraepithelial neoplasia. All modes exhibited higher diagnostic rates compared with the WLI mode. The pathological HP diagnosis rate (consistency) of HP infection was the greatest in the LCI group (endoscopic findings and pathological consistency). The BLI-BRT mode exhibited the highest pathological diagnosis rate for atrophic gastritis and the BLI/BLI + ME mode exhibited the highest diagnostic rate for intestinal metaplasia and low-grade intraepithelial neoplasia.

[Change of ROCK1 Gene Expression Level in Patients with Acute Lymphoblastic Leukemia and Its Clinical Significance].

OBJECTIVE: To investigate the expression change of ROCK1 gene in patients with acute lymphoblastic leukemia (ALL) and its prognostic significance. METHODS: Sixty patients with ALL were selected in our hospital from April 2017 to April 2018, and 60 healthy persons subjected to physical examination were selected as control. The venous blood was taken from the subjects, and then the mononuclear cells were separated. The ROCK1 gene expression level in the samples was detected by RT-PCR, and the expression level of ROCK1 protein was detected by Western blot. The correlation between ROCK1 gene expression and clinical characteristics of ALL patients was analyzed by using statistical methots. RESULTS: The RT-PCR showed that the relative expression level of ROCK1 gene in ALL patients was 1.37 (1.28-1.46), which was significantly higher than that in the control group (P<0.05). Western blot showed that the protein expression level of ROCK1 in ALL patients was higher than that in the control group (P<0.05). The expression level of ROCK1 gene correlated with age, WBC count, lactate dehydrogenase (LDH) level, peripheral blood immature cell count, and risk stratification of ALL patients (P<0.05). The expression level of ROCK1 gene did not correlate with sex, hemoglobin (Hb) level, platelet count and immunophenotype in ALL patients (P>0.05). The standard risk ratio of B-ALL and T-ALL patients with low ROCK1 expression was significantly higher than that in patients with high ROCK1 expression (P<0.05). The high risk ratio of B-ALL and T-ALL patients with low ROCK1 expression was significantly lower than those with high ROCK1 expression (P<0.05). The ratio of CR in the group with low ROCK1 expression patients was significantly higher than that in patients with high ROCK1 expression (P<0.05). The Relapse rate of the group with low ROCK1 expression was significantly lower than that of the group with high ROCK1 expression (P<0.05). Kaplan-Meier survival analysis showed that OS and DFS in ALL patients with low ROCK1 expression were superior to those in ALL patients with high ROCK1 expression (P<0.05). Multiple factor Cox regression analysis showed that age and ROCK1 gene were independent influencing factors for OS (P<0.05); leukocyte count and ROCK1 gene were independent influencing factors for DFS (P<0.05). CONCLUSION: The expression level of ROCK1 gene in ALL patients is high, which may stimulate the genesis of ALL, and the down-regulation of ROCK1 gene expression may help improve the therapeutic effect for ALL patients.

Double-catheter lavage combined with percutaneous flexible endoscopic debridement for infected pancreatic necrosis failed to percutaneous catheter drainage.

BACKGROUND: Infected pancreatic necrosis (IPN) is a serious local complication of acute pancreatitis, with high mortality. Minimally invasive therapy including percutaneous catheter drainage (PCD) has become the preferred method for IPN instead of traditional open necrosectomy. However, the efficacy of double-catheter lavage in combination with percutaneous flexible endoscopic debridement after PCD failure is unknown compared with surgical necrosectomy. METHODS: A total of 27 cases of IPN patients with failure PCD between Jan 2014 and Dec 2015 were enrolled in this retrospective cohort study. Fifteen patients received double-catheter lavage in combination with percutaneous flexible endoscopic debridement, and 12 patients underwent open necrosectomy. The primary endpoint was the composite end point of major complications or death. The secondary endpoint included mortality, major complication rate, ICU admission length of stay, and overall length of stay. RESULTS: The primary endpoint occurrence rate in double-catheter lavage in combination with percutaneous flexible endoscopic debridement group (8/15, 53%) was significantly lower than that in open necrosectomy group (11/12, 92%) (RR = 1.71, 95% CI = 1.04 - 2.84, P < 0.05). Though the mortality between two groups showed no statistical significance (0% vs. 17%, P = 0.19), the rate of new-onset multiple organ failure and ICU admission length of stay in the experimental group was significantly lower than that in open necrosectomy group (13% vs. 58%, P = 0.04; 0 vs. 17, P = 0.02, respectively). Only 40% of patients required ICU admission after percutaneous debridement, which was markedly lower than the patients who underwent surgery (83%; P < 0.05). CONCLUSIONS: Double-catheter lavage in combination with percutaneous flexible endoscopic debridement showed superior effectiveness, safety, and convenience in patients with IPN after PCD failure as compared to open necrosectomy.

The outcomes of initial endoscopic transluminal drainage are superior to percutaneous drainage for patients with infected pancreatic necrosis: a prospective cohort study.

BACKGROUND AND STUDY AIM: The commonly used minimally invasive methods for patients with infected pancreatic necrosis (IPN) are initial endoscopic transluminal drainage (ETD) and percutaneous catheter drainage (PCD), which are followed, if necessary, by endoscopic or surgical necrosectomy. This study intends to explore which of the two minimally invasive treatments leads to a better prognosis. PATIENTS AND METHODS: Patients with IPN and an indication for intervention were prospectively enrolled and underwent either initial ETD or PCD followed, if necessary, by endoscopic or surgical necrosectomy. RESULTS: Initial treatment success occurred in 8 of 11 patients after ETD (72.7%) and in 3 of 13 patients after PCD (30.8%) (risk ratio [RR] with ETD, 2.36; 95% CI 0.97-5.77; P = 0.04). After 1 year of follow-up, 72.7% of patients survived with ETD, and 69.2% survived with PCD (RR 1.05; 95% CI 0.63-1.75; P = 0.85). Intestinal fistula seems to have occurred less in the patients who received initial ETD rather than PCD therapy (9.1 vs. 38.5%; RR 0.24; 95% CI 0.03-1.73; P = 0.098). Fewer patients who underwent an initial ETD were transferred to surgery (9.1 vs. 46.2%; RR 0.20; 95% CI 0.03-1.40; P = 0.047). A higher rate of new-onset diabetes (3 cases) or impaired glucose tolerance (1 case) occurred in initial PCD compared to ETD (40 vs. 0%, P = 0.042). CONCLUSION: The outcomes of initial endoscopic transluminal drainage are superior to percutaneous drainage for patients with infected pancreatic necrosis (ChiCTR-ONRC-13003653).

A quick screening model for symptomatic bacterascites in cirrhosis.

BACKGROUND: Diagnosis of spontaneous bacterial peritonitis in cirrhosis can be made when a patient has an ascites polymorphonuclear leukocyte count ≥250/mm3. However, symptomatic bacterascites, which is a variant of spontaneous bacterial peritonitis with signs of infection but an ascites polymorphonuclear leukocyte count <250/mm3, cannot be confirmed until the time-consuming ascites culture becomes positive. Currently, early indicators for symptomatic bacterascites remain undetermined. AIMS: To develop a quick screening model for early detection of symptomatic bacterascites in cirrhosis. MATERIALS AND METHODS: Data on patients with cirrhotic ascites from two hospitals (from 2010 to 2014) were collected retrospectively. Patients with symptomatic bacterascites were enrolled in the case group and compared with patients without any infection in the control group. Logistic regression analysis was used to build a model for screening symptomatic bacterascites, and a receiver operating characteristics curve was used to assess the model. RESULTS: In total, 103 patients were enrolled in the case group and 204 patients were enrolled in the control group. A screening model was constructed based on body temperature, abdominal tenderness, blood neutrophil percentage, blood total bilirubin, prothrombin time, and ascites nucleated leukocyte count. The area under the receiver operating characteristic curve was 0.939; a screening score of 0.328 was the best cutoff value. CONCLUSION: Patients with suspected symptomatic bacterascites can be quickly screened according to the developed model, and a screening score ≥0.328 indicates symptomatic bacterascites.
