[Behavior of insulin, C-peptide and proinsulin levels in serum in the course of acute pancreatitis].
14 patients with acute pancreatitis during 16 episodes of the disease were studied. The concentration was measured of blood glucose, serum insulin (IRI), serum C-peptide (CP) using two methods: with Byk-Mallinckrodt kits and with more specific M-1221 antibodies Novo, and of serum proinsulin (Pro) in fasting state on days 1, 2, 3, 5 and 10 after the acute onset. Apart from some sporadic rises in the initial period of the disease, the blood glucose level did not change significantly, and had rather a decreasing trend. The mean serum IRI concentration was 0.17 +/- 0.17 (SD) nmol/l, and it decreased on the 5th day to 0.06 nmol/l 0.04 nmol/l, rising again to 0.11 +/- 0.15 nmol/l on the 10th day. The serum Pro concentration was on the same days: 11.1 +/- 12.6, 4.2 +/- 2.4 and 7.5 +/- 10.8 pmol/l, while the serum CP concentration determined with M-1221 antibodies was 0.48 +/- 0.50, 0.34 +/- 0.19 and 0.52 +/- 0.25 nmol/l respectively. However, when for serum CP determinations the Byk-Mallinckrodt kits were used, the concentration of this peptide was on the 1st day 1.90 +/- 1.12 nmol/l, and it decreased over the following days to 1.08 +/- 0.98 on the 5th day, but remained on the same level on the 10th day (1.11 +/- 0.46 nmol/l).(ABSTRACT TRUNCATED AT 250 WORDS)
