Systemic sclerosis induced by the use of cocaine: is there an association?

Abstract

The association between cocaine abuse and systemic sclerosis (SSc) is rarely described. Two new cases of this association are presented: two young adults, after using inhaled cocaine for a few years, were diagnosed with SSc. While a 24 year-old white female patient presented with diffuse SSc with multiple digital ulcers and scleroderma renal crisis (SRC), a 27 year-old male patient presented limited SSc with skin ulcers and digital gangrene, rapidly evolving to death due to massive intestinal hemorrhage. The authors performed a literature search and found only eight previously published cases. The clinical picture of these patients shows a predominance of vascular involvement, including multiple ulcers and SRC. There is no association with specific SSc autoantibodies. The concomitance of alcohol and other drugs abuse, as well as the presence of drug adulterers, complicates a clear understanding of the role of cocaine in SSc patients.
