[Aliphatic diamines and histamine in the serum of patients with chronic polyarthritis].

The concentration of histamine, cadaverine, putrescine as well as spermidine and spermine was measured in blood serum of patients with rheumatoid arthritis (RA). In comparison to normals there is no statistically significant difference in the concentration of putrescine and spermidine in blood serum of RA patients. Spermine which could be detected in all samples too did not show distinct abnormalities from healthy subjects. Histamine and cadaverine present in measurable amounts were only in particular cases. A relation between increased histamine and basophile count was not demonstrable. There is apparently no correlation between histidinemia which is reported in the literature for RA patients in blood serum and plasma, and histamine production in the blood.
