Evaluation of periodontal status and cytokine levels in saliva and gingival crevicular fluid of patients with inflammatory bowel diseases.

BACKGROUND: Periodontal diseases and inflammatory bowel diseases (IBD, ulcerative colitis [UC] and Crohn disease [CD]) have been reported to present with increased salivary and gingival crevicular fluid (GCF) concentrations of cytokines. The aim of this study was to evaluate the salivary and GCF levels of TNF-α, IL-1ß, IL-10, and IL-17A and their associations with the periodontal statuses of UC, CD, and non-IBD patients, and to analyze the interrelationships among these cytokines, IBD conditions, and periodontal diseases. METHODS: This cross-sectional study was performed with a total of 131 patients (62 women and 69 men, mean age 42.96±13.02 years). Patients were divided into three groups: UC, CD, and non-IBD. Periodontal status was defined according to the 2017 World Workshop Disease Classification. Salivary and GCF cytokine levels were analyzed using ELISA. RESULTS: UC and CD patients diagnosed as having periodontitis and gingivitis presented with significantly higher levels of TNF-α and lower levels of IL-10 as compared with non-IBD patients (p<0.05). UC patients diagnosed with periodontitis exhibited significantly higher scores of bleeding on probing (p = 0.011) and increased salivary and GCF IL-1ß levels as compared with CD patients (p = 0.005, and 0.012, respectively). Considering the active and remission status of IBD, salivary IL-1ß was found to be correlated with the parameters representing the severity of periodontal diseases in active UC and CD patients. CONCLUSION: In the presence of periodontal diseases, UC and CD patients showed different expression levels of TNF-α, IL-1ß, and IL-10 in oral secretions as compared with non-IBD patients.

Assessment of salusin alpha and salusin beta levels in patients with newly diagnosed dipper and non-dipper hypertension.

OBJECTIVE: The pathophysiology of non-dipper hypertension has not been clarified. The relationship between salusins with atherosclerosis and hypertension has gained attention in recent years. The aim of this paper is to investigate whether salusins are associated with circadian blood pressure, left ventricular mass index, and diastolic functions in newly diagnosed hypertensives. METHODS: The study included 88 newly diagnosed hypertensive individuals. Twenty-four-hour ambulatory blood pressure monitoring and echocardiographic examinations were performed. The patients were assigned to dipper hypertension (n = 41) and non-dipper hypertension (n = 47) groups based on the ambulatory blood pressure monitoring results according to the presence of ≥ a 10% decrease in nighttime blood pressure values or not. Serum salusin α and ß levels were determined by electrochemiluminescence immunological test method. RESULTS: Compared to dipper hypertension, non-dipper hypertension group demonstrated lower salusin α levels (1818.71 ± 221.67 vs 1963 ± 200.75 pg/mL, p = .002), mitral E/A, septal E'/A' and higher salusin ß levels (576.24 ± 68.15 vs 516.13 ± 90.7 pg/ml, p = .001) and left ventricular mass index. Multivariate logistic regression analysis revealed salusin-α (OR 0.474, 95% CI 0.262 to 0.986, p = .001), salusin-ß (OR 2.550, 95% CI 2.123 to 2.991, p = .018), and left ventricular mass index (OR 2.620, 95% CI 2.124 to 2.860, p = .011) as independent predictors of non-dipper hypertension. As candidate markers to predict non-dipper hypertension, decreased salusin α, and increased salusin ß levels may mediate crosstalk between sympathetic and parasympathetic systems and indicate poor cardiovascular prognosis in hypertension.

Mean platelet volume and response to the first line therapy in newly diagnosed adult immune thrombocytopenia patients: a retrospective study

Background/aim: Immune thrombocytopenia (ITP) is treated by corticosteroids and/or intravenous immune globulin as the first line treatment when necessary. Mean platelet volume (MPV) is a marker of platelet production and function. In this study, we aimed to search the relationship between the MPV and the treatment response in ITP patients and it was hypothesized that MPV can be used as a predictor of the response. Materials and methods: The 70 newly diagnosed adult primary ITP patients and 70 of healthy people were included. MPV between ITP and healthy population, MPV in the diagnosis and after the treatment between the responders and the nonresponders were compared. Results: The responders had significantly higher MPV and the nonresponders had significantly lower MPV than the healthy population (11.09 and 10.21 fL, P = 0.03; 9.38 and 10.21 fL, P = 0.001). MPV in the diagnosis was significantly higher in the responders than the nonresponders (11.09 and 9.38 fL, P = 0.005). MPV significantly changed after the treatment in the responders (11.09 to 9.32 fL, P = 0.004). Conclusion: MPV can be used as a predictor of early response to the first line treatment in newly diagnosed adult primary ITP patients.

Soluble endothelial protein C is associated with blood pressure variability and salt consumption but not mean blood pressure in patients with newly diagnosed primary hypertension.

BACKGROUND: Hypertension is a widespread disease involving frequent thrombotic complications. Blood pressure variability (BPV) has recently been shown to be associated with end-organ damage and cardiovascular events. However, the pathogenesis of the relation between BPV and cardiovascular events has not yet been explained. Soluble endothelial protein C (sEPCR) exhibits a procoagulant effect by reducing the anticoagulant and anti-inflammatory effects of protein C and activated protein C. The purpose of this study was to evaluate sEPCR levels in hypertensive individuals and the parameters affecting that level, particularly BPV. METHODS: Fifty-one newly diagnosed hypertensive subjects and 31 healthy individuals were included in the study. Twenty-four-hour ambulatory blood pressure monitoring (ABPM) was performed after office control, and simultaneous 24-h urine was collected. BPV was calculated with average real variability (ARV) from ABPM data. Blood specimens were collected under appropriate conditions for sEPCR levels and biochemical tests. sEPCR levels were compared between the patient and healthy groups, after which parameters affecting sEPCR elevation in the hypertensive group were evaluated. RESULTS: sEPCR levels were significantly high in the hypertensive group (p < 0.05). At multivariate regression analysis in the hypertensive group, sEPCR was determined to be independently associated with 24-h systolic ARV (ß = 0.572, p < 0.05) and 24-h urine Na (ß = 0.428, p < 0.05). CONCLUSION: In our study, sEPCR was high in hypertensive individuals, and this elevation was related to ARV and urine Na excretion independently of mean blood pressure.

Elevated serum levels of procollagen C-proteinase enhancer-1 in patients with chronic kidney disease is associated with a declining glomerular filtration rate.

BACKGROUND: Procollagen C-proteinase enhancer-1 (PCPE-1) is a 55 kDa glycoprotein, which increases the activity of procollagen C-proteinases that break down C-terminal propeptides. Studies have shown that PCPE-1 is involved in the fibrotic process that occurs in various tissues and organs. Our review of the literature revealed no data concerning the relation between PCPE-1 and chronic kidney disease (CKD). The purpose of this study was to determine PCPE-1 levels in CKD. METHODS: One hundred thirty-one CKD patients and 34 healthy controls were included in our study. Demographic data were recorded, and routine biochemical tests were performed. Blood specimens were collected for PCPE-1 investigation. Demographic data, biochemical test results and PCPE-1 levels were compared between the control and patient groups. Parameters affecting PCPE-1 levels in our patient group were assessed. RESULTS: Procollagen C-proteinase enhancer-1 levels were significantly higher in our patient group compared to the control group. Parameters affecting PCPE-1 elevation in the patient group were identified as systolic blood pressure, blood urea nitrogen, phosphorus, haemoglobin, intact parathormone levels, glomerular filtration rate and body mass index. CONCLUSION: We determined high PCPE-1 levels in CKD patients. PCPE-1 levels being negatively correlated with glomerular filtration rate suggests that PCPE-1 may be associated with progression in CKD patients.

The Influence of Warfarin Adherence on Time in Therapeutic Range Among Patients with Mechanical Heart Valves.

BACKGROUND: Despite considerations of its therapeutic range and multiple drug-food interactions, warfarin is the mainstay of oral anticoagulation in patients with mechanical heart valves (MHVs). The quality of anticoagulation demonstrates variations, with 'time in therapeutic range' (TTR) values usually lower than expected. It has been hypothesized that warfarin adherence is among the modifiable causes of suboptimal coagulation. The aim of the study was to demonstrate the ability of the 8-Item Morisky Medication Adherence Scale (MMAS-8©) to identify patients with non-adherence to warfarin, and to define the predictors of optimal coagulation when a TTR value ≥65% is used as the surrogate. METHODS: In a cross-sectional survey of 112 patients, TTR6 months and TTR12 months were calculated using the Rosendaal method. A questionnaire was used to assess the patients' warfarin knowledge, bleeding complications, and adherence. Patients were categorized into low-adherence (LA), moderate adherence (MA) and high-adherence (HA) groups based on MMAS-8 values. The target INR was 2.5-3.5, and an effective TTR was defined as ≥65%. RESULTS: TTR6 months, TTR12 months and warfarin knowledge were significantly lower in the LA group than in the MA and HA groups. In addition, the bleeding score of HA patients was significantly lower than that of LA and MA patients. The MMAS-8 was the single independent predictor of effective TTR for six and 12 months on multivariate regression analysis (B = 0.506, p <0.001 and B = 0.469, p <0.001, respectively). CONCLUSIONS: Warfarin adherence accounted for poor TTR values in patients with MHV, and MMAS-8 was used effectively to identify those expected to have a low TTR, to suffer more complications, and to require robust education.
