ACTA ENDOCRINOLOGICA (BUC)

Corticosteroids are systemically or locally used agents in treating many skin disorders. Besides their benefits within the correct indications, they may also increase many adverse reaction risks. Systemic absorption of topical glucocorticoids may rarely cause Iatrogenic Cushing Syndrome (ICS) in the geriatric population. On the other hand, to the best of our knowledge, ICS cases coexisting with pyoderma gangrenosum (PG) have not been reported before in the geriatric population. Herein, we aimed to present a 67-year-old female patient who developed ICS and was accompanied by PG due to long-term use of topical clobetasol 17-propionate therapy.

Context. Inflammation-related markers may predict cardiovascular diseases. Objective. In this study, it was aimed to assess pentraxin-3 (PTX-3) levels and its relationship with carotid intima-media thickness (CIMT) and high-sensitive C-reactive protein (hsCRP) in patients with subclinical hypothyroidism. Design. Prospective cross-sectional study Methods. This study included 60 patients (aged 30-60 years) with subclinical hypothyroidism and 30 healthy volunteers as controls. The demographic characteristics and anthropometric measurements were performed in all patients and controls. In addition, sonographic carotid artery examination, thyroid functional tests, lipid profile, hsCRP, and PTX-3 levels of the participants were investigated. Results. The PTX-3, hsCRP levels and CIMT were higher in patients with subclinical hypothyroidism when compared to controls (p=0.008, p=0.001, p<0.001, respectively). The PTX-3 level was strongly correlated with hsCRP (r=0.865; p<0.001), but no such correlation was detected with CIMT (r=-0.255; p=0.50). In binominal logistic regression analysis, it was found that CIMT and serum uric acid levels were independent parameters associated with subclinical hypothyroidism. In ROC analysis, a cut-off value of >3.75 ng/mL for serum PTX-3 level predicted subclinical hypothyroidism with a sensitivity of 60% and specificity of 60.7% (AUC: 0.672, p=0.004). Conclusion. Showing inflammation and endothelial dysfunction, the PTX-3 may be a helpful marker in patients with subclinical hypothyroidism associated with increased risk for cardiovascular disease.
