Objective:
To determine the factors affecting the procalcitonin level, and its association with the severity of pancreatitis in patients with acute pancreatitis (AP).
Study Design:
Cross-sectional analytical study.
Place And Duration Of Study:
Division of Gastroenterology, University of Health Sciences, Diyarbakır Gazi Yasargil Education and Research Hospital and Department of Gastroenterology, Dicle University School of Medicine, Diyarbakır, Turkey, between April 2017 and June 2021.
Methodology:
The study included 214 patients diagnosed with AP according to Atlanta criteria. By checking the PCT and CRP values of the patients in the first 12 hours, the relationship with these scales that predict the severity of pancreatitis was statistically examined.
Results:
Hundred and fifty-two patients (71.0%) had mild, while 62 patients (29.0%) had severe pancreatitis. According to the Atlanta criteria, the mean PCT level of patients with mild pancreatitis was 1.4±0.7 ng/mL, while the mean PCT level of patients with severe pancreatitis was 9.0±12.3 ng/mL (p<0.001). The diagnostic performance of PCT was better for predicting severe AP. For the 0.94 ng/mL cut-off, PCT had 86.9% sensitivity and 50.7% specificity. (AUC=0.731[95% CI: 0.669-0.811]; p<0.001; LR: 1.7). In patients with severe pancreatitis, the PCT level was 4.7±18.5 ng/mL in patients without concomitant infection and 15.8±8.1 ng/mL in patients with concomitant infection (p<0.001).
Conclusion:
High PCT value measured at the time of the first admission to the hospital may predict severe pancreatitis. In addition, a high PCT value at the time of admission to the hospital in patients with pancreatitis may indicate another concomitant infection.
Key Words:
Acute pancreatitis, Coinfection, Procalcitonin, Severity of pancreatitis.

01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

01:24Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
