Abstract

 Background & Objective: Tumor-infiltrating lymphocytes (TILs) develop as recognition and defense against malignant cells by the host immune system. T cells are the most tumor infiltrating immune cells. There are controversial data about intratumor T cells and many have proposed diverse mechanisms for dysfunction of TILs. The aim of this study is analyzing Tumor Infiltrating T lymphocytes in patients with breast cancer by immunophenotyping.

 Methods: Sixteen women suffering from breast cancer were examined thirteen of them were confirmed histologically to be invasive ductal carcinoma (IDC). Tissue samples from patients and matched control group were processed for analysis by flow cytometry.

 Results: Results indicated that human breast cancer contain variable numbers of TILs. No significant changes in the percent of intratumor CD45+, CD3+ and CD3+/CD45+ cells were observed between studied group. Also there were no significant differences between cancer patients (group 1 and 2) and control group in the case of infiltration and activation status of T cells subpopulations. CD4+ cells in IDC patients and CD8+ cells in patients with other tumors (ILC+AMC) were the most infiltrated TILs. Intratumor TCD8+ cells expressed HLA-DR markers significantly more than CD25 as activation marker. In this investigation we could not find any correlation between TIL and both size and clinical stages of tumor.

 Conclusion: An immune infiltrate is an invariable finding in breast cancers, with considering the activation marker expression, TIL may be activated, albeit partially. Understanding the insensitive and/or suppressive nature of cancer cells to the immune system may provide important insights into tumor escape mechanisms as well as the development of anti-cancer strategies.

Abstract

  Background & objectives: There are growing evidences about relationship between vitamin D metabolism and occurrence of diabetes mellitus. Vitamin D has a role in secretion and possibly the action of insulin and modulates lipolysis and might therefore contribute to the development of cardiovascular diseases. This study was aimed to evaluate whether serum vitamin D3 level in patients with diabetes is lower than that in non-diabetics and if its level has any relation to indices of metabolic syndrome.

 Methods: Sixty nine subjects were enrolled in this case-control study (23 diabetic patients with good control of blood sugar, 23 poor control diabetic patients and 23 healthy subjects as control group). Serum 25(OH) D3, Fasting Blood Sugar (FBS), (2 hour postprandial blood sugar) BS 2hpp, triglyceride (TG), total cholesterol, HDL and HbA1C were measured. We also measured blood pressure, body weight, height and abdomen circumference for individuals. The data were analyzed by Anova, Chi-square and Pearson correlation.

 Results: Serum levels of Vitamin D3 were significantly lower in diabetics compared to non diabetics. (36/5±16/6 v.s. 56/6±19/1 nmol/lit, p<0/001). There was no statistical difference between the group with good control diabetes and poor control diabetes. There was no significant correlation between low serum vitamin D and metabolic syndrome parameters. These findings suggest the need for ongoing evaluation of possible protective role of vitamin D3 supplement in the development of diabetes.

 Conclusions: Based on our results vitamin D deficiency is prominent in patients with diabetes. It appears the vitamin D level should be monitored in diabetic patients.
