Background and Objective: Systemic sclerosis (SSc)
is a systemic autoimmune disease which associate
with erectile dysfunction (ED). However, there was no
previous study in Thailand. This research aimed to
study the prevalence and risk factors of ED in SSc
patients.
Methods: A cross-sectional analytical research to
explore the prevalence and risk factors of ED in SSc
patients at the outpatient department of Khon Kaen
Hospital during 2nd May 2017 – 31st May 2018 using
the International Index of Erectile Function-5 (IIEF-5)
questionnaire.
Results: A total of 59 male participants found that
93.22% had ED and did not attempt intercourse. A
45.76% did not attempt intercourse. In the sexually
active group 32 men, the prevalence of ED was 87.5%
(95% CI, 71.01-96.49) which 43.75% were severe ED,
3.13% were moderate ED, 12.5% were mild to
moderate ED, 28.12% had mild ED, while only 12.5%
had no ED. Risk factor of ED is diffuse cutaneous
systemic sclerosis (dcSSc) with Odds ratio 10.57
(95%CI, 1.08-103.59, p=0.043).
Conclusions: The majority of male SSc patients had
ED and did not attempt intercourse. The significant
risk factor is dcSSc.
