Comparison of the effect of hydrocortisone, hydrocortisone-17-butyrate and betamethasone on collagen synthesis in human skin in vivo.
It has been shown previously that topical corticosteroid treatment decreases collagen synthesis in human skin in vivo and that the adverse effects are due to reduced collagen synthesis. The aim of the present study was to evaluate the effect of hydrocortisone, hydrocortisone-17-butyrate and betamethasone on collagen synthesis in human skin in vivo. Fourteen healthy male volunteers applied hydrocortisone, hydrocortisone-17-butyrate, betamethasone and vehicle twice a day for one week to four separate areas marked on their abdominal skin. The collagen synthesis rate in the skin was measured by assaying collagen propeptides from the suction blisters induced on the treated areas. Aminoterminal propeptide of type I procollagen (PINP) and aminoterminal propeptide of type III procollagen (PIIINP) were measured from skin blister fluid using radioimmunoassays. Skin thickness was measured with ultrasound. Hydrocortisone decreased the two propeptides studied in the suction blister fluids less than did hydrocortisone-17-butyrate and betamethasone, but the interindividual variation was great. Hydrocortisone-17-butyrate and betamethasone had almost similar decreasing effects on the propeptides in the suction blister fluid. Hydrocortisone decreased the concentrations of PINP and PIIINP by about 35%. In some subjects (4/14) the decline of the collagen propeptide levels was over 50%. The decline in the concentration of PINP was 63% by hydrocortisone-17-butyrate and 69% by betamethasone, while the decrease in PIIINP was 55% by hydrocortisone-17-butyrate and 62% by betamethasone. None of the treatments had any effect on skin thickness within one week. In conclusion, it seems that hydrocortisone is less atrophogenic than hydrocortisone-17-butyrate and betamethasone, as shown by radioimmunoassays for collagen propeptides. The order of inhibitory potency of the three glucocorticoids on collagen synthesis was hydrocortisone < hydrocortisone-17-butyrate < betamethasone. Thus, assay of collagen propeptides from suction blisters can be used to screen various steroids with respect to their action on collagen synthesis.[1]References
