[Risk factors of hypertension in IgA nephropathy].

OBJECTIVE: To explore the risk factors of hypertension in patients with IgA nephropathy in South China. METHODS: The clinical and renal pathological data of 280 primary IgA nephropathy patients diagnosed by biopsy were analyzed to extinguish the risk factors of hypertension. RESULTS: A total of 96 patients were suffered with hypertension (34.3%). A single-variable analysis showed that the age (>or= 40 years), body weight (>or= 60 kg), absence of macrohematuria, duration of disease (>or= 60 months), blood urea nitrogen >or= 8 mmol/L, serum creatinine (>or= 133 micromol/L), hyperuricaemia, degree of 24 h-proteinuria (>or= 1.5 g), segmental glomerular lesions (>or= 25%), globe glomerular sclerosis (>or= 10%), tubular atrophy (>or= 25%), interstitial fibrosis (>or= 25%), interstitial inflammation (>or= 25%) and arteriole hypertrophy (>or= 10%) were all risk factors related to hypertension; multivariate logistic regression analysis showed that serum creatinine, age, arteriole hypertrophy, body weight and 24 h-proteinuria were the independent risk factors. CONCLUSION: Many factors were related the hypertension in patients with IgA nephropathy, while serum creatinine, age, arteriole hypertrophy, body weight and 24 h-proteinuria were the independent risk factors of hypertension.
