title: [Interleukin-1 beta in patients with primary immunocomplex glomerulonephritis].
abstract: Interleukin-1 is one of the most important pro-inflammatory cytokines whose role in the pathogenesis of glomerulonephritic process was proved in numerous studies. The aim of this study was to determine the urinary level of this cytokine in patients with primary immunocomplex glomerulonephritis and its significance in diagnosis of this disease. This prospective study comprised a total of 96 patients (84 males and 12 females) with primary immunocomplex glomerulonephritis. The elevated urinary IL-1 beta level was noticed in 43 (49.4%) patients with different histological forms of glomerulonephritis. The mean concentration was significantly higher in patient's group (57.7 +/- 120.7 pg/mg creatinine) (range 1.1-731) compared to control group (10.2 +/- 5.96 pg/mg creatinine) (range 1.6-25.4) (p < 0.05). There was no significant difference in the frequency of elevated urinary IL-1 beta concentration in different patients group based on histological type of glomerulonephritis (chi 2 = 6.377, p > 0.05). On the basis of our results we concluded that the elevated concentration of IL-1 beta in majority of patients with primary immunocomplex glomerulonephritis had suggested its role in the pathogenesis of glomerulonephritic process. The urinary level of IL-1 beta represents a novel, non-invasive parameter in the diagnosis of this disease, but its measurement is not useful in predicting the histological type of primary immunocomplex glomerulonephritis. The results of our study suggest the possibility that urinary IL-1 beta level reflects the activity of glomerulonephritic process and it could be useful in non-invasive monitoring of the disease progression.
