Serum gastrin I (GLU-GLY-PRO-TRYP-LEU(GLU)6-ALA-[formula, see text]-GLY-TRY-MET-ASP-PHE-CO-NH2) concentrations were investigated by radioimmunoassay in 50 mothers and their newborn infants immediately after birth. The mean serum gastrin concentration in maternal blood was 52.80 +/- 13.37 (SD) pg/ml, and in cord blood 84.12 +/- 42.90 (SD) pg/ml. Both values were significantly higher than serum gastrin levels found in normal, healthy, nonpregnant women (Mean +/- SD = 32.34 +/- 18.35 pg/ml). There were no statistically significant differences in the cord serum gastrin concentrations with respect to sex, weight and length of the infant and age and parity of the mother.

Hepatic porphyrias are characterized by neurological symptoms manifested by abdominal pain, neuropathies and mental aberrations. Porphyrins are ubiquitous and essential biochemical constituents of living beings acting as mediators of oxidation reaction in the metabolism of the steroid, drugs, environmental chemicals or as a mean of exchanging gases, such as oxygen and carbon dioxide between the environment and the tissue of the body using endogenous polypeptide properties. The different porphyrins arising from the arrangement of normal heme synthesis are characterized by an accumulation and excretion of specific intermediate porphyrins and/or of precursors exerting toxic effect, initiating cascades of generations of polypeptides, neurotransmitters and gut-brain axis peptide responsible for the symptoms of clinical status. We studied polypeptide levels in 27 patients (19 females, 8 males) presenting acute attack of hepatic porphyria: 2 with ALA dehydratase-deficient porphyria; 9 with acute intermittent porphyria; 12 with porphyria cutanea tarda and 4 with variegate porphyria. During acute attacks of porphyria, polypeptides were found to be constantly increased: vasoactive intestinal polypeptide (VIP); neurotensin (NT); substance P; pancreatic polypeptide; gastrin-releasing peptide; gastrin and motilin. Administration of the somatostatin (antagonizing polypeptide), which was undetectable or low before treatment, apparently alleviated the acute symptomatology. Elevated levels of polypeptides, at least partly, contribute to appearance of acute symptoms in porphyria patients.
