Summary. Introduction: Alpha hydroxy acids (AHA) are a special group of organic acids found in many natural nutriments. They have been described in literature for the treatment of a number of conditions in which abnormal keratinization consistently contributes to pathogenesis. These include ichtyoses, warts, psoriasis, eczema and acne. Adapalene modulates cellular keratinization and inflammatory processes, and thus is highly comedolytic and anti-inflammatory. This latter effect is due to inhibition of the lipoxygenase activity and also to the oxidative metabolism of arachidonic acid. Aims: The aim of present study was to compare the efficiency and skin tolerance of a topical alpha hydroxy acid preparation and topical retinoid adapalen on mild to moderate acne, all in order to reduce acne. Experimental part: Group consisted of 35 subjects who were divided in two sub-samples. Within the first experimental sub-group 2ml of 40% solution of AHA (Dr Murad fruid acids 40%) was applied to all subjects (Nsg1=15), once a week. Within second experimental sub-group), 0,05% Adapalen (Airol cream) was applied to all subjects (Nsg2=20), once a day. Testing areas were 5x5 cm, left and right cheek, parallel. Therapy lasted for 7 weeks. For data statistical analysis and interpretation of results, software program "SPSS version 13" was used. Results were expressed through the descriptive statistics, as simple frequencies, while for establishing of statistically significant differences, t test of significance was used. Results: The results of this study showed that alpha hydroxy acid and adapalen had a significant effect in the treatment of mild to moderate acne by reducing the number of lesions (non-inflamed and inflamed). Furthemore, fewer side-effects were experienced by patients treated with AHA when compared to adapalen. Conclusion: Topical AHA and topical adapalene had overall efficiency and superior therapeutic dimension.

KORISNI EFEKTI LOKALNO PRIMENJENIH SUPSTANCI U LEČENJU BLAŽIH DO UMERENIH OBLIKA AKNI
Kratak sadržaj: Uvod: α-hidroksi kiseline (AHAs) predstavljaju posebnu grupu organskih kiselina koje su prisutne u mnogim prirodnim proizvodima. Ove kiseline se u literaturi pominju u tretmanima u kojima abnormalna keratinizacija doprinosi stalnim patološkim procesima, koji uključuju ihtioze, pojavu bradavica, psorijazu, ekcem i akne. Adapalen menja ćelijsku keratinizaciju i inflamatorne procese, a takođe ima i komedolitičko i protiv zapaljensko dejstvo. Ovi efekti nastaju kao posledica inhibicije aktivnosti lipooksigenaze, kao i oksidativnog metabolizma arahidonske kiseline. Ciljevi: Cilj istraživanja je bio poređenje efikasnosti i tolerancije kože na primenu preparata sa alfa-hidroksi kiselinama i retinoidom adapalenom, kod blažih do umerenih oblika akni, a sve u cilju smanjenja akni. Eksperimentalni deo: Uzorak je sačinjavalo 35 ispitanika, podeljenih u dva subuzorka. U okviru prvog subuzorka, svim ispitanicima (Nsg1=15), aplikovano je 2ml 40%-nog rastvora α-hidroksi kiselina (Dr Murad voćne kiseline 40%) jednom nedeljno. U okviru drugog subuzorka, svim ispitanicima (Nsg2=20), aplikovan je 0.05%-tni Adapalen (Airol krema), jednom dnevno. Testirane površine kože levog i desnog obraza, bile su 5x5 cm, paralelno. Terapija je trajala 7 nedelja. Za statističku analizu podataka i interpretaciju rezultata u upotrebi je bio softver "SPSS verzija 13". Rezultati su izraženi putem deskriptivne statistike u vidu učestalosti, dok je za utvrđivanje statistički značajnih razlika korišćen t test značajnosti. Rezultati: Rezultati ovog istraživanja su pokazali da α- hidroksi kiseline i adapalen imaju veliku ulogu u tretmanu, kojim se smanjuju akne redukcijom broja lezija (neinficiranih i inficiranih). Šta više, manje neželjenih efekata, imali su ispitanici tretirani α- hidroksi kiselinama u poređenju sa ispitanicima tretiranim adapalenom. Zaključak: Topikalna α-hidroksi kiselina i topikalni adapalen pokazali su ukupnu efikasnost i superiornu terapeutsku dimenziju.
