Survival prognostic factors and markers of morbidity in Spanish patients with systemic sclerosis.
-To identify survival prognostic factors and markers of morbidity among patients with systemic sclerosis (SSc).
Patients and Methods--The study included 72 patients diagnosed with SSc.
According to the extent of skin involvement, three groups of patients were established :
group 1, without sclerosis and with sclerosis of fingers and neck ;
group 2, with sclerosis of face and distal to elbows and knees ;
group 3, with generalised sclerosis including the trunk.
All patients were included in a study protocol to determine visceral involvement.
Cumulative survival after first symptom has been estimated according to the Kaplan-Meier method.
The association between a hypothetical prognostic factor and cumulative survival after first symptom was assessed by log rank test.
The association between a hypothetical risk factor and the prevalence of severe morbity was assessed by the odds ratio.
Multiple logistic regression models were used to identify the main predictors of severe morbidity.
--Survival was estimated to be 85% 10 years after first SSc symptom.
Survival was higher among SSc patients with skin involvement distal to elbows and knees than among the rest of patients ; a forced vital capacity (FVC) on spirometry lower than 70% of expected value was associated with a shorter survival, even after adjustment for diffuse SSc.
Skin involvement proximal to elbows or knees was associated with a higher prevalence of severe morbidity (OR=46.57 ; p<0.001). (...)
