Global 30-day morbidity and mortality of surgery for perforated peptic ulcer: GRACE study.

BACKGROUND: There is little international data on morbidity and mortality of surgery for perforated peptic ulcer (PPU). This study aimed to understand the global 30-day morbidity and mortality of patients undergoing surgery for PPU and to identify variables associated with these. METHOD: We performed an international study of adults (≥ 18 years) who underwent surgery for PPU from 1st January 2022 to 30th June 2022. Patients who were treated conservatively or had an underlying gastric cancer were excluded. Patients were divided into subgroups according to age (≤ 50 and > 50 years) and time from onset of symptoms to hospital presentation (≤ 24 and > 24 h). Univariate and Multivariate analyses were carried out to identify factors associated with higher 30-day morbidity and mortality. RESULTS:  1874 patients from 159 centres across 52 countries were included. 78.3% (n = 1467) of the patients were males and the median (IQR) age was 49 years (25). Thirty-day morbidity and mortality were 48.5% (n = 910) and 9.3% (n = 174) respectively. Median (IQR) hospital stay was 7 (5) days. Open surgery was performed in 80% (n = 1505) of the cohort. Age > 50 years [(OR = 1.7, 95% CI 1.4-2), (OR = 4.7, 95% CI 3.1-7.6)], female gender [(OR = 1.8, 95% CI 1.4-2.3), (OR = 1.9, 95% CI 1.3-2.9)], shock on admission [(OR = 2.1, 95% CI 1.7-2.7), (OR = 4.8, 95% CI 3.2-7.1)], and acute kidney injury [(OR = 2.5, 95% CI 1.9-3.2), (OR = 3.9), 95% CI 2.7-5.6)] were associated with both 30-day morbidity and mortality. Delayed presentation was associated with 30-day morbidity [OR = 1.3, 95% CI 1.1-1.6], but not mortality. CONCLUSIONS: This study showed that surgery for PPU was associated with high 30-day morbidity and mortality rate. Age, female gender, and signs of shock at presentation were associated with both 30-day morbidity and mortality.

Effect of bariatric surgery procedures on serum cytokine and Nesfatin-1 levels.

BACKGROUND: and Purpose: Obesity is known to cause chronic inflammation. We aimed to evaluate the changes in Nesfatin-1 and serum cytokine levels of patients who underwent sleeve gastrectomy or gastric bypass surgery. METHODS: A total of 30 patients with BMI>35 and undergoing bariatric surgery were divided in two group, sleeve gastrectomy (SG) (group-1), Roux-en-Y gastric bypass (RYGB) (group-2). Demographic data, weight, BMI, AST, ALT, blood glucose, CRP values, and IL-1ß, IFN-α, IFN-γ, TNF-α, MCP-1, IL-6, IL-8, IL-10, IL-12p70, IL-17A, IL-18, IL-23, IL-33 cytokine, and Nesfatin-1 values were noted at the time of hospitalization and in the 6th month postoperative follow-up. RESULTS: The mean age of the patients was 37.56 ± 11.73 years, and there were 16 females and 14 males in the study. Body weight and excess body weight change were slightly higher in RYGB patients than in SG patients. In RYGB and SG patients, a significant decrease was found in glucose, AST, ALT, CRP, IL-6, IL-10, and IL-18 values compared to the preoperative period, and serum Nesfatin-1 levels were significantly increased in RYGB patients and not significantly in SG patients. There were also significant decreases in IL-1ß levels in RYGB patients. On the other hand, a decrease in cytokines was observed in both surgical methods, except for IL-17A, although it was not significant. CONCLUSION: The present study showed that there is also a regression in inflammation, which can be associated with NLRP3 inflammasome, due to weight loss after bariatric surgery, more specifically in RYGB.

Type 2 diabetes mellitus remission in sleeve gastrectomy patients: Role of enteroendocrine response and serum citrulline and I-FABP levels.

INTRODUCTION: This prospective cohort study examines the relationship between post-sleeve gastrectomy (SG) weight loss and serum citrulline, I-FABP levels, and the I-FABP/citrulline ratio in obese patients, alongside the correlation with type 2 diabetes mellitus (T2DM) remission. METHODS: 88 participants were enrolled, including 48 undergoing SG and 21 with T2DM. 40 healthy individuals served as controls. Preoperative and 1-year postoperative assessments included citrulline, I-FABP, glucose, insulin, HbA1c, and C peptide levels. RESULTS: Significant weight loss and T2DM remission (11/21) were observed post-SG. Preoperatively, patients had low citrulline and high I-FABP levels, which normalized postoperatively. A positive correlation was found between the I-FABP/citrulline ratio and weight, BMI, glucose, insulin, and C peptide levels. CONCLUSION: SG not only induces enterocyte dysfunction and mass recovery but also may facilitate T2DM remission and alleviate obesity-related effects on the enteroendocrine system. These findings highlight the potential beneficial effects of SG on enteroendocrine function in obese patients.

Could we use PD-1 and PD-L1 expression on lymphocytes and monocytes as predictive markers for prognosis of acute biliary pancreatitis?

PURPOSE: This study aimed to assess the significance of immunophenotyping and serum cytokines in predicting the clinical progression of acute biliary pancreatitis (ABP). MATERIALS AND METHODS: Cytokine levels, T-helper, cytotoxic T, natural killer (NK) cells, monocytes, HLA-DR, and PD-1, as well as PDL-1 immune checkpoints, were measured in ABP patients at the time of diagnosis and compared with results from healthy volunteers. The study also compared leukocyte counts, hematocrit, immunophenotyping results, cytokine statuses, and PD-1, PDL-1 expression between healthy volunteers and ABP subgroups categorized by pancreatitis severity. RESULTS: The study included 65 ABP patients and 20 healthy volunteers. Significant differences were observed between groups in hematocrit, leukocyte counts, total monocytes, lymphocytes, CD3+ total T cells, CD4+ Th cells, PD-1 expression on CD4+ and CD8+T lymphocytes, HLA-DR expression on CD14+ monocytes, NK cells, PD-L1 expression on CD14+ monocytes, classical and intermediate monocytes, as well as levels of IL-6, IL-8, IL-10, IL-18, and IL-33 cytokines. Moderate correlations were found with lymphocyte counts, PD-1+CD4+ cells, PD-L1+CD14+ cells, and strong correlations with HLA-DR+CD14+ cells. Hematocrit, CD3+ total T cells, NK cells, CD4+PD-1 + T cells, and CD8+PD-1 + T cells showed independent associations with the severity of ABP. Lymphocyte counts, CD14+HLA-DR+ cells, CD14+PD-L1+ cells, CD4+PD-1 + T cells, classical, and intermediate monocytes exhibited the highest Area Under the Curve rates in determining organ failure. CONCLUSIONS: Hematocrit, lymphocyte counts, CD14+HLA-DR+ cells, CD14+PD-L1+ cells, and intermediate monocytes emerged as parameters most closely associated with the severity and these parameters could be useful in predicting the severity of ABP.

Is peripheral blood immunophenotyping useful to understand the etiology of Idiopathic Granulomatous?

BACKGROUND: The etiology of idiopathic granulomatous mastitis (IGM) has not been clearly established. However, autoimmunity has recently become popular in etiopathogenesis. We aimed to investigate the immunophenotyping of immune cells to help clarify the etiopathogenesis of the disease. METHODS: Patients with IGM and healthy volunteers were included in the study. Patients were divided into active and remission groups based on their disease status. The ratios of total T cells, helper T cells, cytotoxic T cells, natural killer cells, regulatory T cells, and monocyte subtypes were measured using flow cytometry. In addition, age, complete blood count for leukocyte, lymphocyte, neutrophil, and eosinophil counts, and the smoking status of all volunteers were evaluated. RESULTS: A total of 33 volunteers, including 11 patients with active IGM, 10 patients with remission IGM, and 12 healthy volunteers, were included in the study. The neutrophil, eosinophil, neutrophil/lymphocyte, and non-classical monocyte values were significantly higher in IGM patients than in healthy volunteers. Additionally, the CD4+ CD25+ CD127- regulatory T cell was significantly lower in IGM patients than in healthy volunteers. Furthermore, neutrophil, neutrophil/lymphocyte ratio, CD4+ CD25+ CD127- regulatory T cells, and non-classical monocytes showed significant differences when IGM patients were divided into active and remission groups. IGM patients had higher smoking rates, but this was not statistically significant. CONCLUSION: The changes in many cell types evaluated in our study were similar to the cell profiles of some autoimmune diseases. This could provide minor evidence to suggest that IGM is an autoimmune granulomatous disease with a local course.

Cytokines the Etiology of Idiopathic Granulomatous Mastitis.

OBJECTIVE: To investigate the roles of cytokines in the etiopathogenesis of idiopathic granulomatous mastitis (IGM). DESIGN: Case-control study. PLACE AND DURATION OF STUDY: Istanbul Training and Research Hospital, Istanbul, Turkey, from September 2020 to January 2021. METHODOLOGY: Idiopathic Granulomatous Mastitis patients in active or remission who were admitted to the breast diseases outpatient clinic and healthy volunteers were included prospectively in the present study. The IL-1ß, IFN-α2, IFN-γ, TNF-α, MCP-1, IL-6, IL-8, IL-10, IL-12p (p70), IL-17A, IL-18, IL-23 and IL-33 values were measured with Flow Cytometry. The blood samples were taken before the treatment in the active IGM group. The ages, physical examination findings, menopausal and smoking conditions, and treatment methods were also evaluated. RESULTS: A total of 32 patients including 19 patients with active and 13 in remission, and 18 controls, were inducted making up a total of 50 subjects. The mean age was 37.18±7.15. The IL-1ß, TNF-α, IL-10, and IL-18 values were lower in patients with IGM than in the control group. Granulomatous Mastitis patients smoked more than the healthy participants. When the active patients, remission patients, and control group were evaluated together, no significant differences were detected in cytokine levels. CONCLUSION: The autoimmune and granulomatous reactions may not play a role in the etiopathogenesis of IGM because of the low levels of Th1 and Th17-related cytokines. However, some to baseline reference ranges were established. KEY WORDS: Idiopathic granulomatous mastitis, Cytokine, Autoimmunity, Smoking.
