Calcinosis: insights from other calcinoses.

ABSTRACT

PURPOSE OF REVIEW This review examines the current knowledge and recent developments in the field of vascular calcification focusing on the emerging role of senescence and inflammation in driving this disorder and exploring the overlap and relevance of these pathways to calcinosis in rheumatic disease. RECENT FINDINGS: Vascular calcification is an age-associated disorder. Recent studies have identified DNA damage, cellular senescence and consequent inflammation as key drivers of vascular smooth muscle cell osteogenic change and mineralization. Similar ageing and inflammatory factors are associated with calcinosis in rheumatic disease and some are targets of experimental drugs currently undergoing clinical trials. SUMMARY: Calcinosis in the vascular system and in rheumatic disease share similarities in terms of biomineralization and cardiovascular outcomes. Although research into the role of senescence and inflammation has recently been advanced in vascular calcification, little is known about the mechanistic role of inflammation in calcinosis in rheumatic disease. This review explores whether lessons from one calcinosis can be transferred and applied to the other to provide further insights and inform treatment strategies.
