It is evident the need to improve new methods, predominantly morphologic and molecular, that are able to further exploit the study of the material from the prostatic biopsy. As to the profile of the molecular markers used in both studied groups, there was no significant difference in the sense of outlining an additional prognostic factor in the clinical practice.
Phagocytic functions by neutrophils/ monocytes and biochemical parameters were assessed in peripheral blood of patients with periodontitis, whether or not associated to type 2 diabetes, or patients with type 2 diabetes, or systemically healthy people. Fifty-eight participants were divided into four groups: Control – systemically and periodontally healthy patients (C, n=16), Periodontitis (P, n=14), Type 2 Diabetes (DM, n=11) and Periodontitis associated with type 2 diabetes (DMP, n=17). Blood samples were used to analyze phagocytic activity and the production of superoxide anion using optical microscopy. Significantly lower phagocytic activity of neutrophils was observed in non-opsonized samples (p = 0.008, Kruskal- Wallis) of the periodontitis group and in opsonized samples (p = 0.029, Kruskal-Wallis) of the periodontitis associated with type 2 diabetes group when these groups were compared to the healthy individuals when a 20:1 yeast: phagocyte stimulus was used. Periodontitis patients, whether associated (p = 0.0007, sensitized; Kruskal-Wallis, 20:1) or not with diabetes (p = 0.018 and 0.0007, in the proportions 5:1 and 20:1 yeast: monocyte respectively in sensitized samples; Kruskal-Wallis) also showed lower phagocytic function of monocytes compared to the control group. There was no significant difference in the production of superoxide anion among the evaluated groups. Severe clinical attachment loss was associated with lower levels of HDL in periodontitis patients and a higher percentage of A1C in diabetes with periodontitis patients (p< 0.05; Pearson and Spearman correlations, respectively). Patients with both associated diseases had higher levels of triglycerides and CRP (p < 0.001, Kruskal-Wallis) compared to patients with diabetes only. The results of the present study suggest that periodontitis negatively interferes with the innate immune response and may represent a major risk of systemic complications such as cardiovascular disease in diabetic patients or even in healthy individuals.
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.
