|February 25, 1989
Summary
Minimal changes disease in adults, particularly those over 50, often presents as nephrotic syndrome without renal insufficiency. Spontaneous remission occurred, and corticosteroid treatment was effective with few complications.
Area of Science:
- Nephrology
- Internal Medicine
Background:
- Minimal changes disease (MCD) is a primary cause of nephrotic syndrome in adults.
- Older adults (>50 years) with MCD represent a significant subgroup with potentially different clinical courses.
Purpose of the Study:
- To describe the clinical presentation, treatment response, and outcomes of adult patients with biopsy-proven minimal changes disease.
- To specifically analyze characteristics and outcomes in patients over 50 years of age.
Main Methods:
- Retrospective case series of 25 adult patients with MCD confirmed by kidney biopsy.
- Clinical data, including presentation, treatment, and follow-up, were analyzed.
Main Results:
- 32% of patients had "impure" nephrotic syndrome; none developed established renal insufficiency.
- Spontaneous remission was observed in 4 untreated cases.
- All but one treated patient responded to corticosteroids within a month; 40% achieved maintained remission.
- No significant complications from MCD or treatment were noted.
Conclusions:
- Minimal changes disease in adults is generally manageable with corticosteroids, even in older individuals.
- The disease course is often favorable, with a low risk of renal insufficiency and treatment-related complications.
