SEROMUCOID IN LUPUS ERYTHRMATOSUS AND SCLERODERMA.

Seromucoid levels in blood of 50 normal men and in 63 cases of cutaneous collagen diseases were studied. There was a marked rise in the seromucoid level in cases of systemic lupus erythematosus and also a significant rise in scleroderma. This rise in seromucoid level may be a reflection of the degenerative connective tissue.

Treatment of genito-anal lesions in inflammatory skin diseases with PUVA cream photochemotherapy: an open pilot study in 12 patients.

BACKGROUND: Localized skin lesions of the genito-anal region such as in lichen sclerosus et atrophicus or in lichen planus are a burden for many patients, and therapeutic efforts, including therapies with potentially hazardous side-effects, are often unsatisfactory. Recently, PUVA bath photochemotherapy has been proven highly effective in the treatment of various inflammatory skin diseases, including localized scleroderma. Another form of topical PUVA therapy, 8-methoxypsoralen-containing cream or gel preparations, has been proven to be as effective as PUVA bath therapy for palmoplantar dermatoses. OBJECTIVE: We evaluated the clinical effects of PUVA cream photochemotherapy in patients with genital lesions of inflammatory skin diseases. METHODS: Twelve patients with lichen sclerosus et atrophicus, lichen planus, vulvar eczema and pruritus vulvae were included in the study. PUVA cream therapy was performed up to 4 times a week. RESULTS: PUVA cream photochemotherapy induced a significant clinical improvement of genital lesions in most patients, as revealed by clinical examination. Clinical improvement (reduction in size of lesions of erythema, and/or of pruritus) was achieved in most patients after 10-20 treatments and was reduced in patients that had only received 5-15 treatments. Cumulative doses ranged between 4.5 and 180 J/cm(2); all patients tolerated PUVA cream phototherapy well without any side-effects. CONCLUSION: PUVA cream phototherapy represents a highly effective therapy that should be further investigated as an alternative treatment for patients with genital lesions of inflammatory skin diseases.

A minoxidil-related compound lacking a C6 substitution still exhibits strong anti-lysyl hydroxylase activity in vitro.

It has been previously reported that minoxidil inhibits the activity of lysyl hydroxylase (LH), an enzyme which catalyzes the formation of hydroxylysine, which is necessary for proper maturation of collagen at the transcriptional and enzymatic levels. Using the reverse transcriptase-polymerase chain reaction, we confirmed that this inhibition occurred at least at the transcriptional level. Furthermore, we took advantage of this sensitive and rapid method to perform a quantitative structure activity relation study using several compounds structurally related to minoxidil. We found that when the C6 of the pyrimidinyl moiety was substituted, it had to be by a tertiary nitrogen, i.e. an N-piperidin ring for the inhibition of LH mRNA synthesis to be observed. Surprisingly, however, we found that 2,4-diamino-pyrimidin-3-oxide, a new compound lacking an organic moiety para to the nitroxide oxygen, also retained a high inhibitory effect on LH mRNA expression, comparable to that of minoxidil. We thus conclude that the presence of a substituent para to the nitroxide oxygen is dispensable for inhibition of LH mRNA to be observed in vitro. This brings new insights into the design of therapeutic agents useful in any condition where an overproduction of mature collagen is unwanted, i.e. accelerated wound healing, keloids and localized scleroderma.
