Prognostic effect of Nesfatin-1 on the diagnosis and staging of acute cholecystitis.

BACKGROUND: Gallbladder diseases are an important health concern affecting approximately 20% of the population in developed countries. Acute cholecystitis is the most common complication of gallstones. The aim of our study is to determine the use of Nesfatin-1, which is an easily applicable and fast resulting and is thought to have an association with inflammatory events, in the diagnosis and grading of acute cholecystitis. METHODS: Patients who admitted and were hospitalized and treated with the acute cholecystitis diagnosis in Istanbul Training and Research Hospital between July 1, 2020, and December 1, 2020, were included in the study. The patients were divided in threemain groups as mild, moderate, and severe according to Tokyo Guidelines 2018 based on their routine blood tests and imaging results. All patients who are included in the study were tested for their blood leukocyte, neutrophil, lymphocyte, Nesfatin-1 levels, and neutrophil/lymphocyte ratios within the first 24 h of their hospitalization. RESULTS: With at least 15 patients in each group, 61 volunteers in total were included in the study as healthy volunteers, mild, moderate, and severe cholecystitis. The average age of the participants were 58.11±19.76 years. About 47.54% of the participants were female and 52.46% weremale. In the study, Nesfatin-1 levels in the patient groups were found to be lower than the control group. In the subgroup analyzes, Nesfatin-1 values in the middle patient group were found to be significantly lower than the control group; however, there was no statistically significant relationship between the severity of the disease and Nesfatin-1. CONCLUSION: Nesfatin-1 may guide the clinician for the diagnosis of the disease; however, no significant relationship was found between Nesfatin-1 and the severity or stage of the disease.

Flowcytometric Ratios of Immune Cells in the Prognosis and Staging of Acute Biliary Pancreatitis.

OBJECTIVE: To evaluate several lymphocyte subtypes with various parameters that can be applied easily and give fast results for their roles in evaluating the stage and prognosis of acute biliary pancreatitis. STUDY DESIGN: Case-control study. PLACE AND DURATION OF STUDY: The Emergency Department of Istanbul Training and Research Hospital, and Gaziosmanpasa Research and Training Hospital, Turkey, between June 2020 and April 2021. METHODOLOGY: Patients, who admitted to the Emergency Department with acute pancreatitis and treated after hospitalisation, were included in the study. The patients were divided into three groups; mild, moderately severe and severe, according to the 2012 revised Atlanta classification. Hematocrit, creatinine, potassium, sodium values, and flow cytometry ratios of lymphocyte, monocyte, CD4+, CD8+, and regulatory T cells were measured and the difference between the groups were evaluated. Their results were compared with healthy volunteers. RESULTS: A total of 53 persons including 40 with acute pancreatitis (14 mild, 14 moderately severe, and 12 in the severe pancreatitis groups) and 13 healthy volunteers, were included in the study. The average age of the studied participants was 50.9 ±13.42 years, 43.3% males and 56.7% females. Leukocyte values, lymphocyte rates, hematocrit rates, age, hospital staying duration, creatinine, potassium values, CD4+, and CD3+ lymphocyte rates were found to be different at a statistically significant level between the groups. CONCLUSION: High leukocyte, low lymphocyte, high hematocrit, advanced age, elevated creatinine, elevated potassium, low CD4+ T lymphocyte, low CD3+ T lymphocyte, and low lymphocyte/monocyte ratio were identified as poor prognostic indicators.
