Topical Silymarin Cream as a Novel Therapy Versus Salicylic Acid Peels in Acne Vulgaris: A Split-Face Clinical Trial.

BACKGROUND: Acne vulgaris is a common dermatological condition that greatly impacts patients' self-confidence. Ongoing research is conducted to explore new treatment modalities. Silymarin owns special characteristics that qualify it as a possible treatment for acne vulgaris. OBJECTIVE: We evaluated the efficacy and safety of silymarin cream as a new therapeutic option against salicylic acid peels in the treatment of mild to moderate acne vulgaris. METHODS: A split-face, comparative, Quasi-experimental clinical trial included 30 patients with acne vulgaris. Salicylic acid 30% peels were applied as an office procedure to one half of the face every 2 weeks for 3 months. Topical silymarin 1.4% cream was prescribed as a home treatment, twice daily, to the other half of the face for 3 months. The results were evaluated using the Global Acne Grading System (GAGS), photographic evaluation, and patient self-assessment scale. The adverse effects during treatment were recorded. The sample size was calculated by Stata/IC 16.1. RESULTS: After treatment, a significant reduction of GAGS was noted on both sides of the face, with an insignificant difference between both treatments. The comparative photographic evaluation and patient self-assessment scale were also insignificant. Hyperpigmentation was recorded in 2 cases on the salicylic acid-treated side. No side effects for silymarin cream were observed. CONCLUSION: Topical silymarin cream 1.4% showed comparable results to Salicylic acid 30% peels. It can be considered a promising safe treatment modality for mild to moderate acne vulgaris.

Real-life treatment of cutaneous warts with cantharidin podophyllin salicylic acid solution.

Patients often request treatment of their burdensome cutaneous warts. However, a safe and effective treatment for cutaneous warts is lacking. This study evaluates treatment outcome, side effects, and patient satisfaction after topical application of cantharidin 1% podophyllin 2% salicylic acid 30% (CPS1) solution in a large series of children and adults with cutaneous warts. Fifty-two children and 83 adults with warts, treated with CPS1 solution between October 2012 and October 2014, were included. Complete clearance of warts occurred in 86.5% of children and 62.7% of adults treated with CPS1 solution (p < .01). Resolution of warts was partial in 3.9 and 24.1% and absent in 9.6 and 13.2% of children and adults respectively. Side effects were present in 41.2% of children and 46.3% of adults (p = .7). Most common side effects were blistering, pain, and burning sensation. No serious adverse events occurred. On a 10-point scale, median patient satisfaction score was 9.0 (interquartile range 7.8-10.0) and 8.0 (interquartile range 5.1-9.7) for children and adults respectively (p < .01). CPS1 solution is a safe and promising treatment modality with a high clearance and high patient satisfaction rate for the management of cutaneous warts, particularly in children.

Clinical comparison of salicylic acid peel and LED-Laser phototherapy for the treatment of Acne vulgaris in teenagers.

Acne vulgaris treatments usually cause sensitivity, teratogenicity and bacterial resistance. Investigations of other therapeutic techniques, such as phototherapy, are highly relevant. Thus, we compared the effectiveness of two Acne vulgaris treatments in adolescents: peeling with salicylic acid (SA) and phototherapy. Teens were randomly divided into: group I, treatment with SA peels (10%) and group II, treatment with phototherapy (blue LED and red laser lights). Photographs were taken before and after ten sessions of each treatment, carried out weekly, and compared. To compare the differences between the treatments, the Student t-test was used. P values < 0.05 were considered significant. Both techniques are effective therapies for the treatment of acne in teenagers since the number of comedones, papules and pustules decreased significantly at the end of the session. However, when the two treatments were compared, phototherapy showed a significant difference in reducing the number of pustules. The combined use of red and blue lights due to their anti-inflammatory and wound-healing properties is a more efficient alternative for treating Acne vulgaris in relation to SA and proves more reliable and without side effects, improving the adolescents' skin health.

Rapid treatment of mild acne with a novel skin care system containing 1% salicylic acid, 10% buffered glycolic acid, and botanical ingredients.

The biggest hurdle in the treatment of acne vulgaris is patient non-compliance that is due in large part to poor tolerability to common acne medications. As such, new acne treatments must be developed that balance good anti-acne efficacy with excellent tolerability in order to ensure patient adherence and by extension ensure good clinical outcomes. The goal of the present study was to determine the tolerability and efficacy of a novel skin care system, composed of a cleanser, containing 1% salicylic acid and botanical ingredients, and a treatment gel, containing 1% salicylic acid, 10% buffered glycolic acid and botanical ingredients for the treatment of mild acne. In this single-center, open-label clinical study, 25 male and female volunteers used the test cleanser and test gel twice daily over six weeks. Tolerability assessments showed that the skin care regimen was very well tolerated by all study volunteers. Acne severity was significantly reduced by two acne grades at six weeks. Inflammatory lesion counts were significantly reduced, on average, by 59.06% (P ≤ 0.0001), 91.62% (P ≤ 0.0001), 90.85% (P ≤ 0.0001) and by 98.55% (P ≤ 0.0001) at weeks 1, 2, 4, and 6, respectively. Non-inflammatory lesion counts were reduced, on average, by 13.54% (ns), 38.95% (P ≤ 0.0001), 44.48% (P ≤ 0.0001), and by 56.10% (P ≤ 0.0001) at weeks 1, 2, 4, and 6, respectively. Standardized photography also demonstrated a progressive reduction in acne lesions over time. In conclusion, results of the present study suggest that the tested skin care regimen offers rapid acne clearance and excellent tolerability that together may help to improve patient adherence as well as treatment outcome.

Single-center, open-label study of a proprietary topical 0.5% salicylic acid-based treatment regimen containing sandalwood oil in adolescents and adults with mild to moderate acne.

BACKGROUND: A proprietary topical blend of salicylic acid and highly purified sandalwood oil from Australia was used in this open-label study in adolescents and adults with mild to moderate facial acne. METHODS: The investigational regimen consisted of a foaming cleanser, an acne serum, a spot treatment, and a mask. Patients applied the treatment regimen as directed for 8 weeks. The primary efficacy measure was the percentage of patients assessed as improved, much improved, or very much improved according to the Global Aesthetic Improvement Scale (GAIS) ratings at week 8. Severity was rated using the Evaluator's Global Severity Scores (EGSS) at baseline and weeks 2, 4, and 8. Tolerability was assessed at baseline and weeks 2, 4, and 8 by asking patients to rate the severity of itching, scaling, erythema, burning, dryness, and stinging. Patients were also asked to complete an acne questionnaire. RESULTS: 89.4% (42/47) met the primary end point determined by the GAIS of improved (66%), much improved (19%), or very much improved (4%). Notable reductions in lesion counts were observed in patients with more severe or inflamed lesions. Tolerability was queried at all visits. No itching, scaling, or erythema was reported after initial application. Symptoms of intolerability peaked at week 2; however, most events were mild to moderate and were typically reported with use of the mask component. Intolerance decreased by week 4 and by week 8. The treatment regimen was well tolerated by patients. CONCLUSIONS: Results from this study support the use of a proprietary investigational regimen in patients with mild to moderate acne and warrant further investigation to determine whether longer-term therapy (ie, beyond 8 weeks) results in enhanced efficacy with minimal side effects, leading to continued patient compliance and skin improvement.

Control of salicylate intolerance with fish oils.

We report three patients with disabling salicylate-induced intolerance who experienced abrogation of symptoms following dietary supplementation with omega-3 polyunsaturated fatty acids (PUFAs). All three patients experienced severe urticaria, asthma requiring systemic steroid therapy and anaphylactic reactions. After dietary supplementation with 10 g daily of fish oils rich in omega-3 PUFAs for 6-8 weeks all three experienced complete or virtually complete resolution of symptoms allowing discontinuation of systemic corticosteroid therapy. Symptoms relapsed after dose reduction. Fish oil appears a safe and effective treatment for this difficult and often serious condition.

Evaluation of salicin as an antipyretic prodrug that does not cause gastric injury.

Pharmacokinetic and pharmacological studies were performed to compare the antipyretic effects of salicin (SL), saligenin (SG, an aglycone of SL) and salicylic acid (SA, an active metabolite of SL) in rats. When SL was administered orally to rats, SA appeared slowly in the plasma and levels increased gradually, in contrast to the rapid appearance observed after oral administration of sodium salicylate (SANa) or SG. Orally administered SL did not affect the rectal temperatures of afebrile rats at a dose of 5 mmol/kg; at this dose, SANa and SG lowered body temperature significantly. However, it significantly reduced yeast-induced fever, producing a normal body temperature, and completely prevented fever when administered simultaneously with yeast. SL did not induce gastric lesions even at a dose of 5 mmol/kg; conversely, SANa and SG induced severe gastric lesions in a dose-dependent manner at 1, 2.5 and 5 mmol/kg. Poor absorption of SL and rapid absorption of SA and SG were confirmed in an in vivo system, as well as in an in vitro system using everted rat jejunal sacs. Only small amounts of SA and SG were detected in the intestinal tracts of rats 1 h after oral administration, whereas more than 50 % of an SL dose was recovered as SL and SG from the intestinal tracts 1 h after treatment and 15.8 % of the dose was still present as SG 4 h after administration. When given to germ-free rats, 19.8 % of the SL dose was recovered intact, mainly from the cecum, and no SG was detected even at 4 h after treatment. These results indicate that SL is a prodrug which is gradually transported to the lower part of the intestine, hydrolyzed to SG by intestinal bacteria, and converted to SA after absorption. It thus produces an antipyretic action without causing gastric injury.
