Systemic sclerosis & Raynaud's

Impact of Season, Environmental Temperature, and Humidity on Raynaud Phenomenon in an Australian Systemic Sclerosis Cohort

Arthritis Care Res (Hoboken)Published Cohort study

Authors' conclusion

Lower environmental temperature and higher relative humidity had significant associations with worsened RP in this systemic sclerosis cohort

Study context

Population
Patients with SSc in the Australian Scleroderma Cohort Study; mean monthly weather data from the closest weather station to the patient's address
Participants
1,972 patients9,175 visits
Outcome
Patient-reported worsened RP in the month preceding each study visit
Follow-up
Preceding month

Observational data: associations, not effects.

Further findings

Clinical associations of worsened RP

Strongly associated with telangiectasia, calcinosis and digital ulceration
Associated with anticentromere antibody and gastroesophageal reflux disease
Negative correlation with diffuse disease

Health-related quality of life (HRQoL) (Short Form 36)

Worsened RP strongly associated with worse HRQoL
