Limited data are available on serum levels of different sphingomyelin (SM) and ceramide (CER) species in acne vulgaris (AV).This study aimed to identify circulating levels of neutral sphingomyelinase activity (N-SMase), ceramide-1-phosphate (C1P), sphingosine-1-phosphate (S1P), C16-C24 SMs and C16-C24 CERs in AV patients and controls.Serum was collected from 30 AV patients and 20 age, gender-matched control subjects. Serum levels of C16-C24 SMs and C16-C24 CERs were determined by an optimized multiple reaction monitoring (MRM) method using ultra fast-liquid chromatography (UFLC) coupled with tandem mass spectrometry (MS/MS). Serum activity of N-SMase was assayed by standard kit methods, C1P and S1P levels were determined by enzyme-linked immunosorbent assay (ELISA).A significant increase was observed in serum levels of C16 SM in patients with AV compared to controls. No significant difference was found in C18 and C24 SM levels between the two groups. Very-long-chain C24 CER was significantly decreased in AV patients compared to controls. Long chain C16-C20 CER levels showed no significant difference between AV patients and controls. A significant positive correlation was found between serum total cholesterol levels and all measured SMs and CERs in both the control and patient groups. Patients with AV had increased circulating levels of C16 SM, C1P and lower circulating levels of C24 CER compared to healthy controls, which may provide prognostic value for the disease.Future studies are needed to understand the role of altered sphingolipid levels in the pathophysiology of AV. |
