Evidence for a viral etiology of Paget's disease of bone
Clinical Orthopaedics and Related Research
|September 1, 1983
Abstract:
Ultrastructural studies of the bone cells in patients with Paget's disease of bone have revealed the presence of nuclear and cytoplasmic inclusions that resemble the nucleocapsids of Paramyxoviridae virus. Immunocytologic studies of bone biopsy specimens and cultured bone cells have demonstrated positive responses with antisera against measles virus and/or respiratory syncytial virus. These observations suggest that Paget's disease may be a slow viral infection of bone. The exact nature of the putative viral agent has yet to be established.
Insights
Paget
Area of Science:
- Virology
- Bone Biology
- Pathology
Background:
- Paget's disease of bone is a chronic condition affecting bone remodeling.
- Etiology remains largely unknown, with viral infections being a suspected cause.
Purpose of the Study:
- To investigate the potential viral etiology of Paget's disease of bone.
- To identify ultrastructural and immunocytologic evidence of viral agents in affected bone cells.
Main Methods:
- Ultrastructural analysis of bone cells from Paget's disease patients.
- Immunocytologic examination of bone biopsy specimens and cultured cells using specific viral antisera.
Main Results:
- Nuclear and cytoplasmic inclusions resembling Paramyxoviridae nucleocapsids were observed.
- Positive immunocytologic responses were noted with antisera against measles virus and respiratory syncytial virus.
Conclusions:
- Findings suggest a possible slow viral infection of bone as the cause of Paget's disease.
- The specific viral agent implicated requires further characterization.
