title: Relationship between hypoalbuminemia, hyperlipidemia and renal severity in patients with lupus nephritis: a prospective study.
abstract: OBJECTIVE
  The purpose is to evaluate the relationship between hypoalbuminemia, hyperlipidemia, nephrotic and renal severity in patients with lupus nephritis.
  
  
  METHODS
  Autoantibodies and serological parameters were measured and analyzed in 429 patients with lupus nephritis in a single centre.
  
  
  RESULTS
  The prevalence for anti-dsDNA, anti-nucleosome and anti-histone was higher in the nephrotic syndrome (NS) patients than that in non-NS patients (p < 0.0001 for all comparisons). The NS patients had a higher proportion of diffuse proliferative renal lesions (69.05%) and membranous lesions (68.00%). Serum total cholesterol and albumin levels were associated with activity and severity of renal disease. The levels of proteinuria and serum albumin were positively correlated with activity and chronicity index (p < 0.001 for all correlations). The incidence of a poor renal outcome (p = 0.0461) in the NS patients was significantly increased. On the other hand, the remission rate (p = 0.0002) was significantly reduced and recurrence rate (p = 0.0027) was significantly increased in NS patients.
  
  
  CONCLUSIONS
  This paper highlights that nephrotic-range proteinuria, elevated total cholesterol level and decreased serum albumin levels may reflect the activity and severity of renal damage in SLE patients.
