Worse prognosis of IgA nephropathy (IgAN) is associated to hypertension, high proteinuria, glomerular and vascular sclerosis. A family story of hypertension (FHT) in relatives could be a strong predictor of the occurrence of hypertension (HT) in children. Renal vascular lesions (RVL) are often observed in normotensive patients with IgAN. In order to evaluate a possible association between FHT and LVR in patients with IgAN, we investigated two groups of 73 IgAN patients, sex (56 males and 17 females) and age matched, according to the presence or not of FHT. FHT was diagnosed if relatives and/or at least one child under 60 years of age had treatment for HT or systolic and diastolic BP over 140/90 mmHg at the time of the survey. Patients entering into the study were followed during an average period of 5 to 8 years. At the end of the study, all patients were explored for HT and renal function. Creatinine clearance (CrCl) was evaluated by Cockcroft and Gault formula and renal failure was defined as CrCl60mL/min. The results were as follow: at the time of renal biopsy, RVL were observed in 73% of males with FHT vs 16% of males without FHT (p0.0001) and 70.6% of females with FHT vs 29.4% of females without FHT (p0.001); at the end of the study period, HT was significantly associated to FHT in 89.6% of patients group with FHT vs 22.6% of HT patients in the group without FHT (p.0001). Renal failure was present in 45.2% of patients with FHT vs 4.1% of patients without FHT (p0.0001). These data suggest: VRL could be dependent of genetic factors; FHT should be an early predictor of VRL in patients with IgAN; FHT might be a risk factor for renal failure in patients with this renal disease. |
