A b s t r a c tBackground: The presented pilot study was conducted in order to evaluate dynamic fluctuations of blood inflammation markers among patients with congestive heart failure (CHF) and coexistent periodontitis (PD). Aim:The study hypothesis stated that elimination of chronic inflammation caused by PD has a significant impact on inflammation markers and, secondarily, also on the course and prognosis of CHF. N-terminal pro-B-type natriuretic peptide (NT-proBNP) and tumour necrosis factor alpha (TNF-a) markers were assessed due to their proven diagnostic significance.Methods: Blood samples were collected at the time of CHF patients' admission to the clinical ward (I examination) and then after 3-9 months (average six months) after periodontal treatment completion (II examination). With antibiotic cover, basic periodontal parameters (such as CAL, PD, PI, BOP) were evaluated, scaling and root-planning were performed, and orthopantomogram X-rays were conducted. Patients received instructions about domestic oral hygiene procedures. Measurements were repeated during a second examination of blood samples. Obtained results were compared and statistically analysed. Results:The initial outcome of the study confirmed the hypothesis that maintaining good and complex oral hygiene has an essential impact on blood concentration of NT-proBNP and TNF-a markers.Conclusions: Exploration of possibilities considering medical help and treatment optimisation seems to be evident also according to improvement of prognosis, therapy effectiveness, and patient comfort. Foregoing conclusions about biomarkers are, according to authors' best knowledge, the first such results reported in medical literature.

Objective Sinus tachycardia is frequently reported in systemic lupus erythematosus (SLE), while there are limited data on post-exercise ability to slow heart rate (i.e. heart rate recovery, HRR) in this group of patients. Methods We studied consecutive 70 patients with SLE and 30 healthy controls. All examined individuals underwent detailed clinical examination, echocardiography, Holter monitoring with heart rate variability and treadmill stress test using Bruce's protocol. HRR values were calculated as the difference between maximum HR during exercise and HR at the first (HRR1) and third (HRR3) minute of rest. Individuals with coronary artery disease, diabetes mellitus and suspected pulmonary hypertension were excluded from further analysis ( n = 15). Results Fifty-five SLE patients were eligible for this study: aged 41.5 ± 12.4 years, 87.3% women, SLICC/ACR-DI score 3.58 ± 1.85. In the SLE group 36.4% patients received beta-blockers, usually for previously detected sinus tachycardia and/or arterial hypertension. Mean HRR1 (36.9 ± 12.6 vs 49.5 ± 18.6, p = 0.0004) and HRR3 (55.5 ± 14.3 vs 69.2 ± 16.4, p = 0.0001) were significantly lower in SLE than in healthy individuals. Significantly negative correlations between SLICC/ACR-DI score and HRR1 ( r = -0.299, p = 0.01), HRR3 ( r = -0.361, p = 0.001) and exercise capacity ( r = -0.422, p < 0.0001) were revealed. Additionally, beta-blocker treatment was also revealed to alter significantly HRR1, HRR3 and exercise capacity in SLE. Conclusion Patients with SLE are characterized by attenuated HRR after exercise. In our study impaired HRR was associated with disease severity and beta-blocker treatment and probably with disease duration. The use of HRR assessment in SLE can be used as an additional marker of cardiac autonomic nervous system dysfunction.

In patients with SSc lasting more than 3 years, the disease is characterized by increased stiffness of the large systemic arteries. Longer duration of SSc leads simultaneously to the increased stiffness of the large systemic arteries and to the progressive impairment of RV function and its coupling to the pulmonary arterial bed.

Improvement of periodontal status may influence decrease of MPV value andincrease of congestive heart failure treatment efficacy and effect patient comfort. It is a new, not frequently used pattern of chronic disease treatment optimalization.

Objectives Patients with systemic lupus erythematosus (SLE) have a higher risk of myocardial involvement, which can result in ventricular dysfunction. The aim of our study was to estimate potential relationship between exercise capacity assessed by six minute walk test (6MWT) and echocardiographic parameters of left and right ventricular function in SLE patients. Methods We prospectively studied 66 SLE patients (57 F, age 44 (20–75) years) and 27 age matched healthy subjects. In addition to routine evaluation, 6MWT and transthoracic echocardiography including LV diastolic dysfunction parameters (E/A, E/É) were performed. Results While E/A was similar in both groups, E/E’ was higher in patients with SLE than in controls, 7.5 (4–22) vs 6.8 (1.6–9.4), p = 0.018. The mean 6MWT distance was significantly shorter in SLE (561.6 ± 150.7 vs 682.6 ± 98.1 m, p < 0.002). Among SLE patients only 53 (80.3%) were capable to walk at least 450 m, while in controls 27 (100%) (p = 0.013). We observed significant correlations between 6MWT distance and SLICC/ACR-DI (rho=−0.44, p < 0.001), E/A (rho = 0.30, p = 0.004), E/E’ (rho=−0.36, p < 0.001) in SLE patients. Univariable logistic regression models revealed that SLICC/ACR-DI, E/E’, tricuspid regurgitant peak gradient (TRPG), and right ventricular systolic pressure (RVSP) were associated with 6MWT distance lower than < 450 m. ROC curves shown high predictive value of E/E’ ratio, TRPG, RVSP in the prediction for 6MWT distance < 450 m. Conclusion Impaired exercise tolerance seems to result mainly from the severity of SLE and LV diastolic dysfunction.
