[Diagnostic criteria for systemic scleroderma]

Diagnostic informative value was studied of a set of N. G. Guseva's diagnostic criteria (1993) for systemic sclerosis (scleroderma). A total of 104 patients with systemic sclerosis (scleroderma) and 126 patients with other rheumatic diseases were examined. The above set of criteria was found out to be of high sensitivity and specificity--99% and 98.4% respectively. The authors present their own modification of the set of diagnostic criteria by N. G. Guseva (1993) which is not inferior in respect of sensitivity and specificity to the original but is more simple, and with a greater potential for further applications, due to which features it can come into widespread use.
