ABSTRACT
OBJECTS The aim of the study was to investigate a possible relationship between plasma renin activity, angiotensin II, serum levels of angiotensin-converting enzyme, aldosterone and markers of immune activation in congestive heart failure (CHF). PATIENTS AND METHODS:
Fifty-three patients (50 male, three female, mean age 46 +/- 16 years) with congestive heart failure were studied. Twenty-eight patients had I or II NYHA class of CHF and 25 patients had III or IV NYHA class (NYHA class, mean +/- SD 2.3 +/- 0.9). Serum neopterin concentration and hormones were measured by commercial radioimmunoassays. Serum soluble receptors of tumour necrosis factor and interleukin-2 were determined by ELISA.RESULTS:
All analytes significantly correlated with NYHA classes (P < 0.05). There existed correlations between neopterin and angiotensin-converting enzyme or aldosterone (rs = 0.35 and rs = 0.36, P < 0.05). The soluble tumour necrosis factor receptor concentrations correlated with plasma renin activity (rs = 0.38, P < 0.05).CONCLUSION:
The result of our study suggest that there exists some relationship between the renin-angiotensin-aldosterone system and immune activation in severe congestive heart failure, however, the associations found are rather weak.
