IntroductionDespite being one of the first diseases to be genetically characterised, β-thalassaemia remains a disorder without a cure in a majority of patients. Most patients with β-thalassaemia receive only supportive treatment and therefore have a poor quality of life and shorter life spans. Hydroxyurea, which has shown to induce fetal haemoglobin synthesis in human erythroid cells, is currently recommended for the treatment of sickle cell disease. However, its clinical usefulness in transfusion-dependent β-thalassaemia is unclear. Here, we present a protocol for a randomised double-blind controlled clinical trial to evaluate the efficacy and safety of oral hydroxyurea in transfusion-dependent β-thalassaemia.Methods and analysisThis single-centre randomised double-blind placebo-controlled clinical trial is conducted at the Thalassaemia Centre of Colombo North Teaching Hospital, Ragama, Sri Lanka. Adult and adolescent patients with haematologically and genetically confirmed transfusion-dependent β-thalassaemia are enrolled and randomised into the intervention or control group. The intervention group receives oral hydroxyurea 10–20 mg/kg daily for 6 months, while the control group receives a placebo which is identical in size, shape and colour to hydroxyurea without its active ingredient. Transfused blood volume, pretransfusion haemoglobin level, fetal haemoglobin percentage and adverse effects of treatment are monitored during treatment and 6 months post-treatment. Cessation or reduction of blood transfusions during the treatment period will be the primary outcome measure. The statistical analysis will be based on intention to treat.Ethics and disseminationEthical approval has been obtained from the Ethics Committee of Faculty of Medicine, University of Kelaniya (P/116/05/2018) and the trial is approved by the National Medicinal Regulatory Authority of Sri Lanka. Results of the trial will be disseminated in scientific publications in reputed journals.Trial registration numberSLCTR/2018/024; Pre-results.

Abstract Objective Psoriasis is an immune-mediated inflammatory skin disease. It can involve any body skin area, particularly the scalp, lower back, elbows, and knees. There are several topical and systemic therapies for the treatment. Nowadays, herbal medicines are popular treatments for dermatologic conditions. This two-arm parallel, randomized placebo-controlled clinical trial was conducted to examine the hypothesis of the efficacy of Melissa officinalis syrup on patients with mild-to-moderate Plaque psoriasis. Result Among 100 patients, 95 participants completed the trial and five of them withdrew. The mean pruritus intensity and PASI scores decreased significantly in the intervention group compared to the placebo group (P < 0.001). The DLQI score in the intervention group increased post-treatment compared to pre-treatment (P = 0.029); however, there was no significant difference between the intervention and control group at the end of the study (0.065). Trial registration: The trial was registered in the Iranian registry of clinical trials on November 9th, 2019 (https://www.irct.ir/trial/43434; registration number: IRCT20191104045326N1).

Abstract Background: Coronary microvascular disease (CMVD) refers to cardiovascular diseases with normal coronary angiography but evidence of myocardial ischemia or microcirculation lesions, often presenting as angina pectoris attack. Coronary artery of microtubules dysfunction is one of the pathogenesis of coronary heart disease,but the occurrence and development and the current of CMVD intervention therapy remains to be further researched.Chinese traditional medicine (TCM)has advantages in the treatment of cardiovascular diseases, therefore, this article describes an ongoing randomized controlled clinical trial, based on the theory of TCM, for the purpose of evaluating the efficacy and safety of Guhong injection ,a Chinese patent medicine,compared with placebo in patients suffering from CMVD. Methods/design: This is a multicenter, randomized, parallel arm, open-label, double-blind, placebo-controlled clinical trial. A total of 260 eligible patients will be allocated and randomly assigned, in a ratio of 1:1, to either the experimental group or the control group. The treatment course is 10 consecutive days, with a 8-week follow-up. The primary outcome is the frequency of angina attacks, Secondary outcomes include myocardial metabolites, ecg changes, quantitative score of TCM syndromes, inflammatory response and endothelial function indicators. Discussion: This trial is strictly designed in accordance with principles and regulations issued by the China Food and Drug Administration (CFDA). The results will provide high quality evidence on the efficacy and safety of Guhong injection in the treatment of CMVD. Trial registration: Chinese Clinical Trials Registry, ChiCTR1900022902.

AbstractBackgroundPremenstrual syndrome (PMS) has a high prevalence among women of reproductive ages but despite its high prevalence, it has no determined and absolute treatment, so far. So, the aim of the present study was to compare the effect Pimpinella Anisum (Anise) with placebo on the intensity of the symptoms of PMS.MethodsThe present study was a randomized double-blind controlled clinical trial. College students who were suffering from PMS and had the inclusion criteria were selected and randomly assigned into two groups of intervention (Anise) and control (placebo). Participants in the intervention group, received 110 mg capsules of Anise three times day (a total dose of 330 mg per day); the control group received similar capsules with the same dosing that contained starch. Consumption of the capsules was started 7 days before the start of the menstruation and continued until 3 days after, which was a total of 10 days during two consecutive menstruation cycles. The intensity of the symptoms of premenstrual syndrome was measured using Premenstrual Symptoms Screening Tool (PSST). To compare the intensity of the symptoms between the two study groups, generalized estimating equation statistical method was used.ResultsEventually, sixty-seven 18–35 year old college students who were suffering from premenstrual syndrome were enrolled in the study. Comparing the mean score of the intensity of the syndrome between the two groups after the first and the second menstruation cycles showed a decrease in the intervention group to 13.9 (p-value<0.001; 95% CI: 16.5,−11.4) and 9.8 (p-value<0.001; 95% CI: 12.4,−7.3), respectively.ConclusionResults of the study showed that, in general, Anise was effective in decreasing the symptoms of premenstrual syndrome in comparison to placebo.

Background:Diabetic foot ulcer (DFU) is one of the most common complications of diabetic patients. Mostly, non-healing DFU leads to infection, gangrene, amputation and even death. High costs and poor healing of the wounds need a new treatment such as alternative medicine. So, the aim of this study was to evaluate the efficacy of Aloe vera/ Plantago major gel (Plantavera gel) in healing of DFUMethods:Forty patients with DFU enrolled in a double-blind randomized clinical trial. The patients who were randomly assigned into the intervention group (n = 20), received topical Plantavera gel in addition to the routine cares, whereas the patients in the control group (n = 20), received topical Placebo gel in addition to the routine cares. Intervention was done twice a day for 4 weeks in the both groups. Photography and an evaluation of DFU healing were conducted by a checklist and then were scored at baseline and at the end of each week. The collected data was analyzed by SPSS software.Results:At the end of the study, there was a significant difference between the two groups in terms of total ulcer score (P<0.001) and Plantavera gel significantly reduced the ulcer surface comparing with the control group (P=0.039). However, there was not a significant difference between the two groups (P=0.263) in terms of the ulcer depth. During this study, no side effect was observed for Plantavera gel in the intervention group.Conclusion:Topical Plantavera gel seems to be an effective, cheap and safe treatment. Of course, further studies are required to confirm the properties of the wound healing of this gel.

Abstract Background Gestational diabetes is the most common medical complication in pregnancy, and it has many side effects for the mother and the fetus. The aim of this study was to evaluate the effect of oat bran consumption on gestational diabetes. Methods This study is a randomized clinical trial that was performed on 112 women with gestational diabetes treated with diet. Participants were randomly divided into two groups of 56. Participants in both groups were given a diet for gestational diabetes. In addition to the diet, the intervention group received 30 g of oat bran daily for 4 weeks at lunch and dinner. Tests of fasting blood glucose and two-hour postprandial (2hpp) glucose were taken from both groups: before the intervention, and 2 and 4 weeks after the start of the intervention. Data analysis was performed using SPSS statistical software (version 22) using independent t-test, as well as Chi-square and Mann-Whitney tests. P values less than 0.05 were considered statistically significant. Results There was no statistically significant difference between the two groups in terms of mean blood glucose before the intervention, while 2 and 4 weeks after the intervention, mean fasting blood glucose and two-hour postprandial (2hpp) glucose decreased significantly in the intervention group compared with the control group (P < 0.001). Conclusion Based on the results of this study, the addition of oat bran to the standard diet for pregnant women with gestational diabetes reduced fasting blood glucose and two-hour postprandial (2hpp) glucose. More detailed studies with higher sample sizes are recommended to prove the effectiveness of this valuable dietary supplement. Trial registration IRCT registration number:IRCT20191220045828N1.

Stress Oxidative

Abstract Background: Curcumin exhibited antioxidant and anti-inflammatory effects. The aim of this study, assess and compare curcumin and nano- curcumin effects on lipid profile, oxidative stress index and inflammatory factors of heart patients.Methods: This Randomized, Double-Blind, Placebo-Controlled Clinical Trial conducted on 90 patients undergoing coronary elective angioplasty. Patients were randomly divided into 3 groups. The first group received a 500 mg capsule of curcumin daily. The second group received an 80 mg capsule of nano- curcumin daily. The placebo group also received capsules similar to curcumin for 8 weeks. Lipid profile, stress oxidative factors and inflammatory markers measured in baseline and end of the investigation.Results: At the end of study, statistically significant changes was seen in the total cholesterol (TC), triglyceride (TG) and low density lipoprotein (LDL) in the intervention groups to the control group (p<0.05). These changes in the nano-curcumin group were greater than the curcumin group. Curcumin and nano-curcumin supplementation also caused a statistically significant improvement in plasma levels of total antioxidant capacity (TAC), malondialdehyde (MDA), Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), high-sensitivity C-reactive protein (hs-CRP), Interleukin 1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) in comparison to the placebo (p<0.05).Conclusion: Complementary therapy of cardiovascular patients with curcumin and nano-curcumin supplements, could improve lipid profile, stress oxidative index and, inflammatory factors. The effects of curcumin on nano formula may be better for cardiac patients due to high bioavailability. However, further investigation is suggested in this regard.
