Paget's disease of bone: an update

Area of Science:

• Bone Biology
• Genetics
• Molecular Medicine

Background:

• Paget's disease of bone (PDB) is a focal skeletal disorder characterized by increased bone remodeling and abnormal bone architecture.
• Current treatments, such as amino-bisphosphonates, are effective in inducing prolonged disease remission.

Purpose of the Study:

• To review recent advancements in the clinical management, genetic predisposition, and molecular mechanisms of Paget's disease of bone (PDB).

Main Methods:

• Literature review of recent findings on Paget's disease of bone.
• Focus on genetic studies, particularly those involving the SQSTM1 gene.
• Analysis of molecular mechanisms and cellular processes affected in PDB.

Main Results:

• PDB exhibits focal areas of heightened bone turnover and altered bone structure.
• Amino-bisphosphonates provide effective and long-lasting remission for PDB patients.
• Significant genetic components are identified, with SQSTM1 gene mutations being a key area of research.

Conclusions:

• Substantial progress has been made in understanding PDB's epidemiology, genetics, and molecular biology.
• An integrated understanding of PDB etiology requires further identification of genetic and environmental factors and their interactions.
• Studying disrupted cellular mechanisms in PDB enhances the comprehension of normal bone remodeling processes.
