Background:HIV infections are a worldwide health problem. HIV infection reduces CD4+ cell counts. Oxidative stress might play an important role in the stimulation of virus replication and immunodeficiency. Saliva might be the first line of defense against oxidative stress.Objective:The aim of this study was to evaluate the oxidative stress marker and antioxidant levels of saliva in HIV-infected patients by measuring total antioxidant capacity and malondialdehyde level.Methods:A total of 49 HIV-positive patients and 49 healthy HIV-negative individuals were randomly selected. All the patients were clinically examined. Five mL of unstimulated whole saliva was collected and evaluated by spectrophotometric assay. Data were analyzed with STATA 11.Results:Mean ages of the case and control groups were 28 and 33 years, respectively. Salivary malondialdehyde levels were significantly higher in the HIV-positive group (3.68±2.26) compared to the healthy control group (2.79±1.91). Levels of salivary total antioxidant capacity were significantly lower in the HIV-positive group (0.20± 0.09) compared to the control group (0.27±0.10).Conclusion:The antioxidant defense system in HIV-positive individuals was low and oxidative stress was high in this population. Saliva might be used as a diagnostic tool for antioxidant changes in HIV-positive patients in the future. There were changes in salivary antioxidant defense system and oxidative stress in HIV-positive individuals. Antioxidant supplements might help local salivary and general health statuses.

Background: One of the most common complications of pregnant women is gestational diabetes mellitus (GDM). Oxidative stress can play an important role in GDM. Objective: The aim of this study was to evaluate salivary antioxidants and oxidative stress markers in GDM. Method: Twenty pregnant women with GDM and 20 healthy pregnant women with normal blood glucose test participated in this study. Five mL of unstimulated saliva samples were collected. Spectrophotometric assay was carried out for sialochemical analysis. Stata software was used for data analysis. Results: The GDM group exhibited no significant difference in salivary total antioxidant capacity and malondialdehyde compared to the healthy control group. All of antioxidants markers, the uric acid, total antioxidant, peroxidase and catalase, decreased in GDM group that the difference of peroxidase and catalase was statistically significant. All of oxidative stress markers, the salivary malondyaldehid, total oxidative stress and total thiol, increased in GDM group. GDM group exhibited significantly higher salivary total oxidative stress levels. Conclusion: Catalase level was significantly lower and total oxidative stress was significantly higher. These two markers might have significant importance and might exhibit early changes compared to other factors in GDM. . Some of salivary antioxidants might have diagnostic, prognostic or therapeutic implications in GDM. Other studies with large sample size on salivary and blood samples need to be done to confirm this properties and salivary samples using instead of blood samples in GDM biomarkers changes.

Background: Diabetes Mellitus (DM) is a progressive metabolic disorder. Objective: The aim of this study was to investigate the relationship between antioxidant and oxidative stress markers in the saliva of patients with type 2 DM and a healthy control group. Methods: In this study, 20 patients with diabetes and 20 healthy individuals were evaluated. Salivary antioxidants markers consisted of total antioxidant capacity (TAC), uric acid (UA), peroxidase and catalase. Oxidative stress markers included total oxidant status (TOS), malondealdehyde (MDA) and total thiol (SH). Sialochemical analysis was performed with spectrophotometric assay. All the statistical analyses were conducted using STATA software. Results: TAC decreased significantly in patients with diabetes. Although salivary UA and peroxidase were lower in patients with diabetes compared to the control group, the difference was not significant. Salivary catalase in patients with diabetes was significantly lower than that in the control group. MDA and TOS exhibited significantly higher levels in type 2 DM. SH levels were slightly higher in DM. Conclusions: According to the results of the present study, there were some changes in the salivary levels of some antioxidants and oxidative stress markers in patients with type 2 DM and could be measured as an indicator of serum changes..
