Changes in Lipid Profile, Liver Enzymes and Inflammatory Factors Following Oral Supplementation with Propolis in Patients with Type 2 Diabetes

Objective: Nutritional ingredients with anti-inflammatory and antioxidant properties such as flavonoids and phenolic acids have been reported in propolis. The present study investigated the effect of propolis supplements on lipid metabolism, liver enzymes, and inflammatory factors in patients with type 2 diabetes. Materials and methods: This clinical trial was performed in a double-blind randomized manner with two parallel intervention (n = 30) and placebo (n = 30) groups. Each group received a capsule (propolis or placebo) of 500 mg 3 times a day for 8 weeks. The lipid profile, liver enzymes, and inflammatory factors were measured at the beginning and end of the study. Statistical analysis was performed by using SPSS software. Results: The mean of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL) levels decreased significantly at the end of the study in the intervention group (p < 0.05). Also, the serum high-density lipoprotein cholesterol (HDL) level increased significantly in this group (p < 0.05). Propolis supplementation significantly decreased C-reactive protein (CRP) and tumor necrosis factor-alpha (TNF-α) (p < 0.05). Also, propolis decreased the mean of aspartate transaminase (AST) and alanine transaminase (ALT) levels, but it was not significant (p > 0.05). Conclusions: Propolis supplementation can be helpful as a dietary supplement in patients with type 2 diabetes by improving status of lipid profile and inflammatory factors in diabetic patients

The effects of supplement propolis on metabolic and antioxidant factors in Type 2 Diabetes

Abstract Backgrand and aim: Diabete is one of the most common metabolic diseases. Oxidative stress and inflammation lead to its pathogenesis and complications. Due to the antioxidant and anti-inflammatory properties of propolis, this clinical trial was conducted to evaluate the effects of propolis supplementation on the metabolism of glucose and lipids, liver enzymes, the antioxidant index and inflammatory status in diabetic patients. Material and Methods: In this study patients with type 2 diabetes were randomly assigned to propolis group (n = 30) and placebo group (n = 30). The first group received a capsule propolis (500 mg) 3 times a day. The second group received the same therapy but a placebo capsule instead of propolis. Glucose-related indicators, lipid profiles, liver enzymes, antioxidant indexs and inflammatory status were evaluated. Results: The results showed a significant decrease in fasting plasma glucose, two-hour postprandial glucose, glycosylated hemoglobin (%), insulin resistance, total cholesterol, LDL cholestrol, triglyceride levels also Tumor necrosis factor alpha, C-reactive protein levels in propolis treated patients compared with placebo. In this study, high density lipoprotein cholestro levels, total antioxidant capacity, glutathione peroxidase and superoxide dismutase in the propolis group was significantly increased. Also the level of liver enzymes (AST and ALT) was not significantly increased. Conclusion: propolis treatment in type II diabetic patients has a beneficial effect on improving blood glucose control, lipid profiles, and inflammatory status and antioxidant indexs. Keywords: Diabetes, Propolis, Glucose Metabolism, Lipid Profile, Inflammatory Status, Antioxidant Indice

The Community-Based Child Health Integrated Program in Iran: A Mixed-Methods Process Evaluation

Objectives: The community-based Child Health Integrated Program (CHIP) was established to improve children’s health status in Iran. The current study was performed to understand how this program was implemented and experienced by the care providers and target group. Methods: A total number of 249 mothers who had children under 5 years (clients) and 70 caregivers (providers) were selected from 42 health care centers of Tabriz city to participate in the study. Quantitative and qualitative data were collected using two separated semi-structured interviews as well as self-developed questionnaires. The mixed-method process evaluation study was examined and reported the exposure and satisfaction status of the clients, and reach, delivery, fidelity rates, and contextual factors toward the CHIP. Results: Overall, low reach (11.2%), moderate-exposure (62.6%), and high satisfaction (80.1%) rates of the clients were reported to the program. The fidelity rate of the program tools was 42.9%, considered as an inadequate rate. Anthropometric measurement and vaccination of the children, as well as face-to-face training sessions for the mothers, were well delivered. However, some parts of the program including follow-up and group training sessions were delivered poorly. Conclusions: This process evaluation study demonstrated that the CHIP is a promising intervention for improving children's health care. However, the barriers identified in this study warrant consideration in subsequent health care needs among children. Further research is required to identify ways to improve the implementation and delivery of this intervention. Practice Implications: There is a dire need to enter some audit and feedback strategies in the form of monthly tracking of process indicators to extent of implementation of intervention components

Propolis supplementation improves glycemic and antioxidant status in patients with type 2 diabetes: A randomized, double-blind, placebo-controlled study

Abstract Objectives: The prevalence of type 2 diabetes has risen dramatically in recent years. There are many different safe therapies used for diabetes and also number of natural supplements that can be used to manage diabetes. We assessed the effect of oral propolis supplementation on blood glucose, insulin resistance and antioxidant status in type 2 diabetes. Methods: We conducted a randomized, double-blinded, placebo-controlled trial for 8-week. Sixty two patients with type 2 diabetes (30-55 years of age) were randomly assigned in two group, propolis (n = 31) and placebo (n = 31). Patients were given doses of 500 mg, three times a day (1500 mg), of propolis or placebo three time a day. The fasting blood sugar (FBS), two-hour postprandial glucose (2-hp), insulin, insulin resistance (IR), hemoglobin A(1)c (HbA(1)c), total antioxidant capacity (TAC) and activity of glutathione peroxidase (GPx) and superoxide dismutase (SOD) were measured at the beginning and end of the study. Statistical analysis was performed using SPSS software. Results: After two month, FBS, 2-hp, insulin, IR, HbA(1)c was significantly decreased in patients treated with propolis compared with placebo group (p < 0.05). Additionally intake of propolis significantly increased the blood levels of TAC and activity of GPx and SOD (p < 0.05). Conclusion: Propolis treatment can be helpful as a diet supplement in patients with type 2 diabetes through improvement in glycemic status, reduction in insulin resistance and amelioration in antioxidant status. This supplement without side effects can increase the effectiveness of prescribing drugs in diabetes.
