Summary

Serum creatinine and activity index are key predictors of diffuse proliferative lupus glomerulonephritis (DPGN) outcomes. Intraglomerular monocyte infiltration may offer a protective effect in DPGN patients.

Area of Science:

  • Nephrology
  • Immunology
  • Pathology

Background:

  • Diffuse proliferative lupus glomerulonephritis (DPGN) is a severe form of lupus nephritis.
  • Accurate prognostic markers are crucial for managing DPGN patients.

Purpose of the Study:

  • To evaluate the prognostic significance of various clinical and biopsy-derived parameters in DPGN.
  • To identify key predictors of short, intermediate, and long-term outcomes in DPGN.

Main Methods:

  • Analysis of 45 DPGN patients' clinical and biopsy data.
  • Proportional hazards analysis to assess prognostic factors.
  • Evaluation of serum creatinine, urinary protein, immunosuppressive doses, activity index (AI), chronicity index (CI), and intraglomerular monocyte count.

Main Results:

  • Serum creatinine (SCr), AI, and intraglomerular monocyte count (NSE index) were significant predictors of outcome.
  • When AI and CI components were analyzed, SCr, NSE index, karyorrhexis, and glomerulosclerosis emerged as significant factors.
  • Intraglomerular monocyte infiltration showed a protective effect.

Conclusions:

  • SCr and AI are powerful predictors of DPGN prognosis.
  • Histologic factors, including specific components of AI and CI, provide additional prognostic information beyond SCr.
  • Intraglomerular monocyte infiltration may play a protective role in DPGN.
