Calcium level may be a predictive factor for pseudocyst formation after acute pancreatitis.

Pancreatic pseudocysts (PPs) are defined as fluid collections more than 4 weeks old that are surrounded by a nonepithelial wall of fibrous or granulation tissue. Many risk factors have been associated with pseudocyst development but predictive factors remain to be explored. The aim of this study was to investigate the clinical, and biochemical parameters that may predict the development of a PPs after an attack of acute pancreatitis (AP). The medical charts of 102 patients diagnosed with AP were enrolled into the study. Demographic, clinical and laboratory details were recorded at admission and at the 48(th) hour. There were several risk factors on admission and at the 48(th) hour that was predictive of PP formation when evaluated by univariate analysis such as: Alanine aminotransferase level at 48 hrs, calcium level at admission, base excess at 48 hrs, calcium level at 48 hrs, and albumin level at 48 hrs. In multivariate analysis, low calcium level at admission was the only variable that was shown to predict formation of PPs. Lower serum calcium level may be a predictive factor for the development of PPs after AP attack. We advise that patients with calcium levels below 8 mg/dl, after AP should be followed more closely.
