Acne vulgaris (acne) is a cutaneous pleomorphic disorder of the pilosebaceous unit involving abnormalities in sebum production and is characterized by both inflammatory (papules, pustules and nodules) and non-inflammatory (comedones, open and closed) lesions. Propionibacterium acnes and Staphylococcus epidermidis are common pus-forming microbes responsible for the development of various forms of acne. This disease remains a common condition in industrialized societies, with many mainstream treatment options available. There are many acne products on the market, and making an appropriate selection can be daunting. Common therapies that are used for the treatment of acne include topical, systemic, hormonal, herbal and combination therapy. Topically used agents are benzoyl peroxide, antibiotics and retinoid. Systemically used agents are antibiotics and isotretinoin. However, all such treatments carry risks and none is completely satisfactory. Natural alternatives are gaining greater research support, and have much to offer clinically in this disorder. This review focuses primarily on herbal treatments for acne that show scientific evidence of clinical efficacy, as well as the more common herbs shown to be useful in the treatment of this dermatologic disorder.

BACKGROUND Acne vulgaris is a pilosebaceous disorder. Bacterial activity and inflammation both influence acne formation. Antibiotics suppress the bacterial activities and elicit anti-inflammatory effects. The overuse of antibiotics may lead to resistance in bacteria. This study was aimed to provide an overview of bacteria that may cause acne and determine their susceptibility to antibiotics.METHODS This was a cross-sectional study sampling from 93 patients with acne in Ciptomangunkusumo Hospital. Comedones were extracted and cultured on Brucella blood agar, under aerobic and anaerobic conditions at 35oC for 24–48 hours. Bacterial identification was performed using Vitek®, and susceptibility test using E-test. Data interpretation was based on the Clinical and Laboratory Standards Institute 2015.RESULTS Staphylococcus epidermidis (50.5%), Propionibacterium acnes (11.0%), and Staphylococcus aureus (7.7%) were identified. Bacteria were not found in 69.2% and 1.1% of samples in anaerobic and aerobic cultures, respectively. P. acnes was susceptible to doxycycline (100%) and minocycline (100%), while 10% was resistant to erythromycin, clindamycin, and tetracycline. S. epidermidis was susceptible to minocycline (100%); but resistant to erythromycin (65.2%), clindamycin (52.2%) and tetracycline (32.6%). The susceptibility of S. epidermidis to doxycycline was 89.1%, which was lower than that of P. acnes (100%). S. aureus was found to be sensitive to minocycline (100%), doxycycline (71.4%), clindamycin (71.4%), and tetracycline (71.4%); but it was resistant to erythromycin (42.9%).CONCLUSIONS Doxycycline and minocycline showed 100% effectiveness for P. acnes. The isolated bacteria were more susceptible to doxycycline compared to tetracycline. The use of clindamycin and erythromycin needs to be limited as most S. epidermidis isolates were resistant to both.

This study intended to develop and evaluate isotretinoin (ITR) loaded nanoparticles taking chitosan as a polymer of interest. Ionic crosslinking method was utilized to prepare nanoparticles. Nanoparticles were formulated using varying ratios (chitosan: tripolyphosphate) and evaluated for its size, distribution of size, zeta potential, percentage of ITR entrapped within nanoparticles, in vitro drug release and its stability under accelerated conditions. The prepared nanoparticles (NPs) were spherical, white in color and free flowing, 321± 4.5 nm was the average size of optimized chitosan nanoparticles and it was able to entrap 88.76 ± 3.5%. The outcomes assured vast promise of the CNs of ITR (optimized) in management of acne and also increasing the therapeutic efficacy, thus establish to be a promising, effective and patient compliant formulation. INTRODUCTION Acne, a cutaneous pleomorphic condition of the pilosebaceous unit involving sebum production rate anomaly and described by inflammatory (pustules, nodules and papules) as well as non-inflammatory comedones (closed and/or open)(Knutson, 1974). Regular pus-forming microbes Propionibacterium acnes and Staphylococcus epidermidis are responsible for development of many forms of acne vulgaris(Rawat, Tripathi et al., 2015). It is a pleomorphic disorder and can manifest at any time during life but it most commonly occurs between ages of 12-24 years, accounting effective 85% of population (Cordain, Lindeberg et al., 2002). P. acne is an anaerobic microorganismexisting in acne lesionsthat promotes inflammation through a variety of mechanisms and involved inproducing pro-inflammatory mediators that diffuses through the follicle wall (Itoh, Tsuchida et al., 2014). Prominent in adolescence and puberty, acne is definitely associated with function of sebaceous gland, which stimulate higher secretion of sebum androgenically (Singh, Gangwar et al., 2016).However, the consequential sebaceous

AbstractVarious Achillea species are rich in bioactive compounds and are important medicinal plants in phytotherapy. In the present study, Achillea millefolium L., Achillea moschata Wulfen, and Achillea atrata L. were compared with respect to their phenolic profile and antibacterial activity against gram-positive bacteria strains (Staphylococcus, Propionibacterium). Particular focus was given to A. atrata, which has hardly been studied so far. Based on the metabolite profile, A. atrata exhibited more similarities to A. moschata than to A. millefolium. The former two only differed in the occurrence of four compounds. The flavonols syringetin-3-O-glucoside and mearnsetin-hexoside, not reported for an Achillea species before, have been detected in A. atrata and A. moschata. All Achillea species reduced growth of the tested bacteria. A. atrata demonstrated highest activity against Propionibacterium acnes and Staphylococcus epidermidis, both being involved in the pathogenesis of acne vulgaris. Furthermore, A. atrata has a pronounced anti–methicillin-resistant Staphylococcus aureus potential. Bioassay-guided fractionation revealed that only the most polar fraction of A. moschata displayed antimicrobial activity, which was attributed to phenolics such as apigenin, centaureidin, and nevadensin, being present in high amounts in A. atrata. Thus, this alpine species shows promising antimicrobial activity and might be a potential source for developing novel dermal/topical drugs.
