Immune-complex glomerulopathy in patients treated with captopril.
Lancet (London, England)
|June 7, 1980
Summary
Captopril treatment may be linked to immune-complex glomerulopathy. Renal biopsies in 13 patients revealed early membranous glomerulopathy in 4, with some experiencing nephrotic syndrome.
Area of Science:
- Nephrology
- Immunopathology
- Pharmacology
Background:
- Captopril is an angiotensin-converting enzyme (ACE) inhibitor widely used for hypertension and heart failure.
- The potential renal side effects of ACE inhibitors, particularly immune-mediated glomerular diseases, require further investigation.
Purpose of the Study:
- To investigate the renal histopathological findings in patients treated with captopril.
- To determine if captopril is associated with the development of immune-complex glomerulopathy.
Main Methods:
- Renal biopsies were performed on 13 patients receiving captopril therapy.
- Histopathological analysis included light microscopy, electron microscopy, and immunofluorescence.
Main Results:
- Four patients exhibited findings consistent with early-stage membranous glomerulopathy (MGP).
- Electron microscopy revealed subepithelial deposits, and immunofluorescence showed a patchy granular pattern in other patients.
- One patient with MGP presented with nephrotic syndrome; another with MGP had a serum-sickness-like syndrome.
Conclusions:
- Captopril use may be associated with the development of immune-complex glomerulopathy.
- The findings suggest a potential link between captopril and glomerular immune complex deposition.
- Further research is warranted to elucidate the mechanisms and clinical significance of this association.
