Summary
This study details POEMS syndrome (polyneuropathy, organomegaly, endocrine disturbance, M-protein, skin hyperpigmentation) in 12 Chinese patients. Findings reveal distinct characteristics and a grave prognosis, with most patients dying within four years.
Area of Science:
- Hematology
- Neurology
- Endocrinology
Background:
- POEMS syndrome (polyneuropathy, organomegaly, endocrine disturbance, M-protein, and skin hyperpigmentation) is rare and less described in Chinese populations.
- Previous studies from Japan and Western countries highlight common features, but data on Chinese patients are limited.
Purpose of the Study:
- To describe the clinical characteristics, diagnostic findings, and prognosis of POEMS syndrome in a cohort of 12 Chinese patients.
- To compare these findings with previously reported cases from other ethnic groups.
Main Methods:
- Retrospective case series analysis of 12 Chinese patients diagnosed with POEMS syndrome.
- Review of clinical data, laboratory results, imaging findings (radiography), and M-protein analysis (immunoelectrophoresis, immunofixation electrophoresis).
Main Results:
- The Chinese cohort showed a predominance of middle-aged males, similar to other populations.
- Lambda M-protein was identified in 7 patients. Diabetic mellitus was notably absent.
- Osteosclerosis was less common; spinal compression fractures were a frequent radiographic finding.
Conclusions:
- POEMS syndrome in Chinese patients presents with some unique features, including a lack of diabetes and different radiographic findings.
- The syndrome carries a grave prognosis, with a high mortality rate within four years despite treatment.
- Further research is needed to understand ethnic variations and improve management strategies for POEMS syndrome.
