Estimation of Plasma Levels of Tumor Necrosis Factor-a, Interleukin-4 and 6 in Patients with Chronic Periodontitis and Type II Diabetes Mellitus.

INTRODUCTION: Both periodontitis and type II diabetes mellitus (T2DM) are common diseases with a multifactorial etiology and have influence of cytokines in their pathogenesis and thus may also influence each other. In recent times, more attention has been given to understanding the influences of these inflammatory cytokines which are a main part of oral chronic inflammation on systemic health of the individuals. Therefore, the aim of this study was to evaluate the plasma cytokine levels, specifically tumor necrosis factor-a (TNF-a), interleukin (IL)-6, and IL-4, in chronic periodontitis patients and T2DM patients, so as to investigate the influence of chronic periodontitis in systemic inflammation associated with diabetes mellitus. MATERIALS AND METHODS: The present study comprised a total sample size of 60 patients. A detailed history along with complete periodontal examination were done for each person. These patients were subdivided into four study groups with 15 subjects (n = 15) in each group: group I: healthy individuals, group II: chronic periodontitis, group III: diabetes mellitus without chronic periodontitis, and group IV: diabetes mellitus with chronic periodontitis. Venous blood was withdrawn for obtaining serum samples from the subjects. Hemoglobin A1c (HbAlc) levels were measured from the automated chromatography. Using enzyme-linked immunosorbent assay kit, TNF-a, IL-4, and IL-6 were measured. RESULTS: It was observed that the difference between almost all the results showed statistical significance. Not much of a difference was seen when TNF-a and IL-6 findings of group II were compared with group III. Furthermore, IL-4 also did not differ when group II was compared with group IV. CONCLUSION: The inflammatory cytokines together control the inflammation process and a balance is maintained. However, in patients with diabetes mellitus, this balance is interrupted, which affects the final development and progression of the disease. Thus, hyperglycemia may be partly associated with the severity of the periodontal status in diabetic patients. CLINICAL SIGNIFICANCE: Hyperglycemia thus may play a role in increasing the severity of the periodontal status in diabetic patients. Keeping such relationship in mind, better treatment modalities can be provided to the patients.

Evaluation of Hemoglobin Concentration and Hematocrit Values in Temporomandibular Joint Ankylosis Patients in Comparison to Nonankylosed Patients.

AIM: The aim of this study is to find if there is any correlation between the hematological parameters and temporomandibular joint (TMJ) ankylosis and severity of the disease in such patients when compared with the nonankylosed patients. MATERIALS AND METHODS: A total of 70 patients with age ranging from 10 to 40 years were included in the study after excluding the subjects according to the inclusion criteria. We categorized the subjects into two major groups: group I: control (nonankylosed/ healthy subjects) and group II: study group (ankylosed subjects) with each group containing 35 subjects (n = 35) respectively. A detailed personal and medical history was obtained. The pharynx diameter was also recorded for each patient, and blood investigations using venous blood were done, which included hemoglobin concentration and hematocrit values. RESULTS: The results of study population showed a mean age of 22 ± 2.2 years. The most common etiology reported was trauma (65.7%) followed by infections, in which Noma was the most common one (80%). The difference of the mean values for hemoglobin and hematocrit concentration, between both the groups, was found to be statistically significant (p < 0.0001). Furthermore, a positive correlation was observed between the hemoglobin concentration and duration of ankylosis. CONCLUSION: This study was an attempt to find a relation between the hemoglobin and hematocrit values in TMJ ankylosis patients so that the clinical treatment and management of such patients during surgeries be improved and may be beneficial for the patient. CLINICAL SIGNIFICANCE: Temporomandibular joint ankylosis patients have to undergo complex surgical treatment, where the risk of excessive blood loss is high. Therefore, considering the complications of blood transfusions, such as infections and other risk factors, these patients can be good subjects for autologous blood transfusions, which help in improvement of the overall well-being of the patient.
