BACKGROUND: Acne vulgaris (AV) is a chronic inflammatory disease in the pilosebaceous unit. Recent research has begun to focus on the essential relationship between oxidative stress and the pathogenesis of AV. The use of antioxidants like coenzyme Q10 (CoQ10) that has various advantages as adjuvant therapy is expected to be beneficial for AV. AIM: The study was aimed to analyze the effect of CoQ10 supplementation on serum SOD levels and the severity of AV patients. METHODS: A double blind-randomized controlled trial was carried out on 36 patients with AV and classified according to severity degree of AV. These patients were randomly divided into two groups (treatment group with tretinoin 0.025% cream and once-daily supplementation of CoQ10 100 mg tablet; and placebo group with tretinoin 0.025% cream and once-daily placebo tablet). Response to treatment was based on serum superoxide dismutase (SOD) level and AV severity degree. RESULTS: Administration of CoQ10 to AV patients significantly increase serum SOD level (p = 0.008) and improves the severity of AV after 8 weeks (p = 0.008). CONCLUSION: CoQ10 supplementation can increase serum SOD levels and improve the severity of AV.
Background: Burn injury defines as skin or tissue damage caused by heat, radioactivity, electricity, or chemicals. Burn injury have an impact on physiological homeostasis. Burn injury will cause an increase in free radicals, it can also cause changes in the platelet count. Melatonin has been proposed as burn supportive therapy because it acts as an antioxidant that can eliminate free radicals. Melatonin can increase the number of the platelets through the mechanism of increasing megakaryocyte fragmentation and modulating the cytokines involved in platelet production. Aim: Proving the effects of melatonin supplementation on the number of platelets in male Wistar rats with third degree of burn injury. Methods: This research was an experimental with randomized control group pre-post test design. Samples are 12 healthy male Wistar rats then randomly divide into two groups, control and experimental group. Each rat was induced 30% burn injury under anesthesia. Rats in control group were given placebo at 0, 8, and 16 hours after burn injury, while rats in experimental group were treated with melatonin intraperitoneal at 0, 8 and 16 hours after burn injury. Blood samples were collected from the retroorbital sinuses at 0, 3, and 24 hours. Data were analyzed statistically by Paired t-Test and Independent t-Test. Results: In control group, the number of platelets at 0-3 hours (p=0,024) and 0-24 hours (p=0,039) showed a significant decrease in platelet count. In experimental group, the number of platelets at 0-3 hours (p=0,047), 0-24 hours (0,015), 3-24 hours (p=0,04) showed a significant decrease in platelet count.Conclusions: Melatonin administration did not cause a significant increase of platelets number. Keywords: Burns, Platelet count, Melatonin
Background: For toddlers younger than 36 months, most of them still use diapers, so diaper rashes frequently appear in the diaper area. To improve the skin barrier, a moisturizer is needed to repair the skin barrier. Besides, the ceramide gold standard of moisturizer for diaper dermatitis, topical ingredients with natural ingredients can be used, for example, topical Aloe vera. Objective: To prove the effectiveness of topical Aloe vera moisturizer compared to other topical ingredients against diaper dermatitis. Methods: The results of the electronic database search Medline Pubmed, Scopus, EBSCOhost, ProQuest, Cochrane library, ClinicalTrials.gov, found 5 articles were included in the qualitative review (n = 289 subjects) and 4 articles (n = 214 subjects) were included in the meta-analysis. Results: Meta-analysis showed that after the administration of topical Aloe vera, there was a mean difference in the score of the degree of diaper dermatitis before and after therapy, the result showed negative value in the studies which were included the treatment group with Aloe vera. This indicates a decrease in the degree of diaper dermatitis after treatment with Aloe vera. The control group also showed that the mean score difference in the degree of diaper dermatitis after administration of control therapy was all negative. This shows that after the administration of therapy in the control group there was also a decrease in the score of the degree of dermatitis. The biggest decrease in the degree of diaper dermatitis was in the study conducted by Murni 2020, which was -2.10 ± 1.39. The lowest decrease in the degree of diaper dermatitis was found in the study conducted by Badelbuu 2019 B which received Chamomile, which was -0.93 ± 1.08. Meanwhile, in the Panahi’s study, the heterogeneity test results showed the value of Q=5,324 df=43; p=0,256, I2=24,866. This shows that the data is homogeneous, it is in line with the results of the statistical Q test and heterogeneity, the results of the I2 test obtained p < 0.001 which also indicates the data is homogeneous. The analysis was carried out using a fixed effect model because the data were homogeneous. The results of the meta-analysis showed that the statistical Q value was z value = -0.969 (p = 0.047). It has quite meaningful results. Conclusion: The meta-analysis showed that statistically there were only slight differences, but there were also studies that provided significant results. Topical application of Aloe vera appears to be more effective. The results of qualitative analysis on other skin barrier function parameters indicate that topical Aloe vera can improve skin barrier function in diaper dermatitis patients. In addition, it provides the same results as standard therapy and several other topical therapies that had been studied which had a good effect on repairing the skin barrier.
