[Renal lesions in myelofibrosis (author's transl)]
Abstract:
In 26 cases of myelofibrosis, the authors investigated for possible renal impairment that can be appraised from the usual clinical, laboratory, and roentgenographic signs. No anomalies were demonstrated in 12 of these cases. In 14 (or 53%) of the patients, some anomaly was discovered : essentially proteinuria with minor alteration of renal function, but also, two cases of poorly functioning left kidney evidenced on intravenous urograms, one case of acute anuric renal failure connected with hyperuricemia, one case of hypokalemic tubulo-interstitial nephritis, and one case of glomerulonephritis with, nephrotic syndrome. This study, when compared to the literature, indicates that besides nephropathy specific to myelofibrosis and attributed to myeloid metaplasia in the kidney, serious consideration must be given to lesions due to (1) compression of the left kidney by the enlarged spleen, (2) urate precipitation in the urinary passages, and (3) a possible glomerular disorder whose mechanism remains undefined.
Insights
This study found that over half of myelofibrosis patients experienced kidney problems, including proteinuria and acute renal failure. These issues may stem from myeloid metaplasia, spleen compression, or urate precipitation.
Area of Science:
- Nephrology
- Hematology
- Oncology
Background:
- Myelofibrosis is a bone marrow disorder.
- Renal impairment can complicate myelofibrosis management.
Purpose of the Study:
- To investigate the prevalence and types of renal impairment in myelofibrosis patients.
- To identify potential causes of kidney damage in myelofibrosis.
Main Methods:
- Clinical, laboratory, and roentgenographic assessments were used.
- 26 myelofibrosis cases were analyzed.
- Literature review was conducted for comparison.
Main Results:
- Renal anomalies were found in 53% of patients.
- Common findings included proteinuria and minor renal function alterations.
- Specific cases showed poorly functioning kidneys, acute renal failure, tubulo-interstitial nephritis, and glomerulonephritis.
Conclusions:
- Renal impairment is common in myelofibrosis.
- Causes include specific myelofibrosis nephropathy, spleen compression, urate precipitation, and undefined glomerular disorders.
