Background: Erectile dysfunction (ED) has been reported among patients with systemic sclerosis (SSc) and primarily limited cutaneous SSc in Caucasians. While there is no data on ED among Thais in whom the diffuse cutaneous SSc subset is common. Objectives: We aimed to estimate the prevalence of ED among Thais with SSc, evaluate its severity, and determine the associated factors. Methods: We did a cross-sectional study among adult Thai male SSc patients. All eligible patients: a) completed the IIEF-15 questionnaire by themselves; b) underwent a genital examination by an experienced urologist to evaluate skin tightness of the penis, scrotum, and phimosis; and, c) were evaluated for Erection Hardness Score. Results: A total of 60 male SSc patients were included. The respective mean age and median disease duration was 54.8±7.2 years and 3.1 years (IQR 1.2–7.2). The definition of ED was fulfilled in 53 cases for a prevalence of 88.3% (95%CI 77.4–95.2), while 65% had severe ED, and none had skin tightness of the genitalia. Eight cases had acquired phimosis, and all were in the ED group. The patients with ED vs. those without ED had significantly lower scores for orgasm, sexual desire, and intercourse satisfaction, and trended to be older, have more severe skin tightness and have higher BMI. Conclusion: ED is a common problem in men with SSc and is mainly categorized as severe. The severity of SSc might increase the risk of developing ED. We found phimosis was a common genital abnormality co-occurring with ED in SSc. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the prevalence of dry eye disease (DED) in patients with both limited and diffuse subtypes of systemic sclerosis (SSc) and to determine the predictive factors associated with the occurrence of DED. Patients and Methods: This was a prospective consecutive cross-sectional study of patients with SSc. Each patient underwent a comprehensive ophthalmological evaluation. The Ocular Surface Disease Index (OSDI) was used to assess the symptoms of DED. Tear break up time (TBUT), Schirmer I and ocular surface staining (OSS) were used for objective tests. Patients were diagnosed DED using the DEW II diagnostic method which included both symptom and objective tests. The collected data of patients with and without DED were compared to find out possible associated factors. Logistic regression analysis was used to determine the effects of these factors. Results: Eighty-four SSc patients (25 limited and 59 diffuse subtypes) were studied. The prevalence of DED in SSc patients was 52.38%. The OSDI, tear break up time (TBUT), Schirmer I and ocular surface staining (OSS) were not significantly different between SSc subtypes. Among the 46 symptomatic patients, DED was noted in 44 (52.38%). Most patients (61.4%) were mixed aqueous deficiency-evaporative dry eye type (both TBUT and Schirmer I test positive). The mean age and the median of disease duration in DED patients were higher than those without DED with statistically significant difference (P = 0.004 and 0.019). Conclusion: DED was common in patients with SSc. The predictors for the occurrence of DED were older age and longer disease duration. Therefore, OSDI and objective tests for DED should be evaluated in all SSc patients, particularly those with older age and longer disease duration. [ABSTRACT FROM AUTHOR]

Thyroid disease, particularly hypothyroidism, has been reported in systemic sclerosis (SSc). Some clinical features of SSc can also present in hypothyroidism. Our aims were to determine the prevalence of, and describe clinical features associated with, hypothyroidism in SSc patients. We conducted a historical cohort study of adult SSc patients who underwent screening thyroid function tests at the Scleroderma Clinic, Khon Kaen University, Thailand, between 2009 and 2018. The patients who had any thyroid disorders before the onset of SSc and were diagnosed as an overlap syndrome were excluded. A total of 200 SSc were included according to sample size calculation, among whom the female to male ratio was 2:1. The majority of cases (137; 69.5%) were diffuse cutaneous SSc subset. The mean age was 55.8 ± 10.7 years and the median duration of disease 4.9 (IQR 1.6–9.9) years. Of the total, 9 had primary hypothyroidism (prevalence 4.5%; 95%CI 2.1–8.4) and 22 had subclinical hypothyroidism (prevalence 11%; 95%CI 7.0–16.2). Of the latter 22, 71% had dcSSc. Logistic regression analysis indicated that unexplained anemia was significantly associated with either subclinical hypothyroid or hypothyroidism (OR 2.74; 95% CI 1.17–6.47), whereas Raynaud's phenomenon had a negative association (OR 0.28; 95% CI 0.11–0.66). Neither severity of skin tightness nor internal organ involvement were associated with hypothyroidism among SSc patients. Clinical-subclinical hypothyroidism is uncommon among SSc patients, it is frequently associated with anemia, and less so Raynaud's phenomenon. Clinical-subclinical hypothyroidism should thus be considered in cases of unexplained anemia in SSc patients. [ABSTRACT FROM AUTHOR]
