Risk factors of hypertension in IgA nephropathy / 中华内科杂志

ABSTRACT

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 (≥40 years), body weight (≥60 kg), absence of macrohematuria, duration of disease (≥60 months), blood urea nitrogen≥8 mmol/L, serum creatinine (≥133 μmol/L), hyperuricaemia, degree of 24 h-proteinuria (≥1.5 g), segmental glomerular lesions (≥25% ), globe glomerular sclerosis (≥10%), tubular atrophy (≥25%), interstitial fibrosis (≥25%), interstitial inflammation (≥25% ) and arteriole hypertrophy (≥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.
