Hrvatsko dermatovenerološko društvo Hrvatskoga liječničkog zbora ustrojilo je radnu skupinu vodećih hrvatskih stručnjaka koji se bave psorijazom. Radna je skupina kritički proučila mjerodavnu znanstvenu literaturu te donijela smjernice za dijagnostiku i liječenje psorijaze., Croatian dermatovenerological society of the Croatian Medical Association formed the working group which consists of leading experts for psoriasis in Croatia. After a critical analysis of relevant scientific papers, the working group has developed guidelines for the diagnosis and treatment of psoriasis

Alopecia areata (AA) is a frequent disease with nonscarring hair loss on the scalp and/or body. Hair follicle in alopecia areata is not irreversibly destroyed, so potential for hair regrowth remains. Considering unknown etiopathogenesis, treatment of AA is symptomatic and directed toward halting disease activity. Lymphocytic inflammatory infiltrate around hair follicle, increased levels of autoantibodies, cytokine abnormalities and increased prevalence of autoimmune comorbidities, support the hypothesis of AA as an organ-specific autoimmune disorder. Therefore, investigations are directed toward new immunomodulatory or immunosuppressive drugs with induction effect on hair growth. New biologic drugs and their influence on hair growth as well as genetic therapy for alopecia areata are currently under investigation. Contemporary principles in therapy of alopecia areata and treatments available will be discussed in this article.

Psoriasis is a chronic, recurrent skin disease that lasts a whole life. A quarter of adults are suffering from severe forms of psoriasis that requires the application of the systemic treatment. Despite the development of new groups of medicines, traditional therapy is still of great importance. Methotrexate, cyclosporine and acitretin are cost-effective and provide excellent disease control. Methotrexate and acitretin are good choice in terms of maintenance therapy, whereas cyclosporin would ideally be used as intermittent therapy. Fear of serious side effects of traditional drugs can be avoided by setting individualized plan for each patient and careful monitoring.

Alopecija areata (AA) česta je bolest koja se očituje neožiljnim gubitkom dlake na vlasištu i/ili tijelu. Folikul dlake u alopeciji areati nije nepovratno uništen, stoga potencijal za ponovni rast kose ostaje. Budući da je etiopatogeneza nepoznata, liječenje AA je simptomatsko i usmjereno na zaustavljanje aktivnosti bolesti. Limfociti oko dlačnog folikula, povišena razina autoprotutijela, poremećaj citokina te udruženost s drugim autoimunosnim bolestima, podupiru hipotezu da je AA organ-specifična autoimunosna bolest. Nova su istraživanja stoga usmjerena na razvoj lijekova koji bi imunomodulatornim ili imunosupresivnim djelovanjem potaknuli rast dlake. Proučavanje utjecaja novih bioloških lijekova na rast kose, kao i razvoj genske terapije u tijeku su. U radu će biti raspravljeni suvremeni principi i dostupne metode liječenja alopecije areate., Alopecia areata (AA) is a frequent disease with nonscarring hair loss on the scalp and/or body.

Psorijaza je kronična, recidivirajuća bolest kože koja traje čitav život. Četvrtina bolesnika boluje od teškog oblika psorijaze koji zahtijeva primjenu sustavne terapije. Unatoč razvoju novih skupina lijekova, tradicionalna terapija i dalje je veoma važna. Metotreksat, ciklosporin i acitretin cijenom su prihvatljivi i pružaju odličnu kontrolu bolesti. Metotreksat i acitretin dobar su izbor u smislu terapije održavanja, dok je ciklosporin idealan kao intermitentna terapija. Strah od teških nuspojava tradicionalnih lijekova može se izbjeći individualnim određivanjem terapije i pažljivim nadzorom bolesnika., Psoriasis is a chronic, recurrent skin disease that lasts a whole life.
