Background:Asthma is a common chronic inflammatory disease of the bronchial airways. Well defined treatment options for asthma are very few. The role of vitamin D3 on asthma is still baffling. Aim: We have examined the effect of vitamin D3 supplementation in mild to moderate persistent asthma patients.Materials and Methods:We conducted an open labeled, randomized comparative trial in 48 asthma patients. The study duration was about 90 days. The study had a run-in-period of 2 weeks. At the end of run-in-period, patients were divided into two groups: Usual care group (n = 31) patients received budesonide and formoterol and intervention care group (n = 32) patients received vitamin D3 supplementation along with their regular medicine.Results:The primary outcome of the study was to measure the improvement in forced expiratory volume in 1 second (FEV1). Patients in both groups had a significant improvement in FEV1 at the end of the study. The mean difference in percentage predicted FEV1 in usual care and intervention care group was 4.95 and 7.07 respectively.Conclusion:The study concluded that adjunctive therapy of vitamin D3 is effective in asthma patients. The present study will be an evidence based report; however, future studies are warranted in longer duration of time to substantiate the present findings.
Introduction: L-carnosine has been found to have multimodal activity. Aim: The aim of this review was to find out the efficacy of Lcarnosine in patients with age-related diseases. Methods: Clinical studies evaluated the effect of L-carnosine on cancer, cardiovascular disease, diabetes, and neurodegenerative disorders were searched in electronic bibliographic databases. The protocol has been registered with PROSPERO (CRD42022314033). The revised Cochrane risk of bias tool for randomized trials was used to assess all of the reports for risk of bias. RevMan 5.4 was used to conduct the meta-analysis. Results: Following the screening process, 14 papers were selected for systematic review, with 9 of them being qualified for meta-analysis. Many of the included studies showed that L-carnosine has potential therapeutic activity in age related diseases. Results from the meta-analysis showed that in diabetes mellitus, HbA1c [mean difference (MD) 95% CI = -1.25 (-2.49, -0.022); p = 0.05; p = 0.001; I 2 = 85%] and fasting blood sugar (FBS) [MD 95% CI = -12.44 (-22.44, -2.44); p = 0.01; p = 0.40; I 2 = 0%] and in neurodegenerative disorder, Wechsler Memory Scale Logical Memory 2 (WMS-LM2) [MD 95% CI = 1.34 (0.83, 1.85); p < 0.00001; p = 0.43; I 2 = 0%], showed statistically significant difference, favoring the L-carnosine group over the control group. While in neurodegenerative disorder, Alzheimer 's Disease Assessment Scale (ADAS) [MD 95% CI = 0.98 (-1.55, -0.42); p = 0.0007; p = 0.86; I 2 = 0%] and Back Depression Inventory (BDI) [MD 95% CI = -1.12 (-1.87, -0.37); p = 0.003; p = 0.73; I 2 = 0%] showed statistically significant difference, favoring the control group over L-carnosine group. Conclusions: Clinical studies were conducted to manage chemotherapy induced toxicities and there are no clinical studies available for its anti-cancer use, and the current evidence does not support its use in the treatment of cardiovascular disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
