Microalbuminuria, a marker of kidney damage, is more common in systemic sclerosis patients. This prospective study highlights its increased prevalence compared to other skin conditions, indicating potential renal involvement in scleroderma.

Area of Science:

  • Nephrology
  • Rheumatology
  • Dermatology

Background:

  • Systemic sclerosis is a complex autoimmune disease with potential multi-organ involvement.
  • Renal complications, including kidney damage, are a significant concern in systemic sclerosis.
  • Microalbuminuria serves as an early indicator of kidney disease.

Purpose of the Study:

  • To investigate the prevalence and incidence of microalbuminuria in patients with systemic sclerosis.
  • To compare urinary albumin excretion in systemic sclerosis patients with control groups.

Main Methods:

  • Prospective study design.
  • Inclusion of 28 patients with systemic sclerosis.
  • Assessment of urinary albumin excretion, proteinuria, and serum creatinine levels.

  • Comparison with two control groups: primary Raynaud's disease (10 patients) and unrelated skin diseases (16 patients).

    • Main Results:

    • At baseline, 3/28 systemic sclerosis patients had microalbuminuria; one had proteinuria.
    • After one year, abnormalities persisted, with two patients showing increased serum creatinine.
    • An additional three patients developed microalbuminuria over the study period.
    • No microalbuminuria was observed in the primary Raynaud's disease control group.
    • Control group with unrelated skin diseases showed lower rates of microalbuminuria and proteinuria, with noted hypertension history.

    Conclusions:

    • Microalbuminuria is more prevalent in systemic sclerosis patients than in age-matched controls with other dermatological conditions and no vascular disease.
    • The findings suggest a higher risk of early renal involvement in systemic sclerosis.
    • Monitoring urinary albumin excretion is crucial for early detection of kidney damage in systemic sclerosis.
