ABSTRACT

Purulent pericarditis in adults is rare, but once it develops, it carries a high mortality rate. Adequate pericardial drainage and proper antibiotic treatment are essential in the successful management of purulent effusions, for which percutaneous catheter drainage is the most commonly performed technique. We herein report the case of a 75-year-old woman with purulent pericarditis attributable to methicillin-resistant Staphylococcus aureus. Although percutaneous pericardial drainage by catheter was used, the drainage was insufficient because of hyperviscous effusion. We performed surgical subxiphoid pericardial drainage, and a piece of a purulent stone was found in the pericardial cavity with purulent effusion. Additionally, daily intrapericardial washouts with physiologic saline alone were used as adjunct therapy. Five weeks later, the patient had a decreasing inflammatory reaction and symptom relief. She was discharged with no complications such as constrictive pericarditis.

ABSTRACT

This study investigated morning levels of pentraxin3 (PTX3) as a sensitive biomarker for acute inflammation in patients with obstructive sleep apnea (OSA). A total of 61 consecutive patients with OSA were divided into two groups: non-to-mild (n = 20) and moderate-to-severe (n = 41) OSA based on their apnea-hypopnea index (AHI) score. Those patients with moderate-to-severe OSA were further divided into continuous positive airway pressure (CPAP) treated (n = 21) and non-CPAP-treated (n = 20) groups. Morning and evening serum PTX3 and high-sensitivity (hs) C-reactive protein (CRP) levels were measured before and after 3 mo of CPAP therapy. The baseline hs-CRP and PTX3 levels were higher in patients with moderate-to-severe OSA than in those with non-to-mild OSA. Moreover, the serum PTX3 levels, but not the hs-CRP levels, were significantly higher after than before sleep in the moderate-to-severe OSA group (morning PTX3, 1.96 ± 0.52; evening PTX3, 1.71 ± 0.44 ng/ml). OSA severity as judged using the AHI was significantly correlated with serum PTX3 levels but not hs-CRP levels. The highest level of correlation was found between the AHI and morning PTX3 levels (r = 0.563, P < 0.001). CPAP therapy reduced evening and morning serum hs-CRP and PTX3 levels in patients with moderate-to-severe OSA; however, the reduction in PTX3 levels in the morning was greater than that in the evening (morning -29.8 ± 16.7% vs. evening -12.6 ± 26.8%, P = 0.029). Improvement in the AHI score following CPAP therapy was strongly correlated with reduced morning PTX3 levels(r = 0.727, P < 0.001). Based on these results, morning PTX3 levels reflect OSA-related acute inflammation and are a useful marker for improvement in OSA following CPAP therapy.

ABSTRACT

BACKGROUND: Sleep-disordered breathing (SDB) is thought to be a state of inflammation caused by hypoxic stress. Whether adaptive servo ventilation (ASV) attenuates the inflammatory response and improves the cardiac function of patients with congestive heart failure (CHF) accompanied by SDB was not been investigated. METHODS AND RESULTS: Seventeen inpatients with New York Heart Association (NYHA) II or III underwent polysomnography. There was a positive correlation between the apnea hypopnea index and high-sensitivity C-reactive protein (hs-CRP) level (r=0.753, P=0.016). The patients were divided into ASV (n=10) and non-ASV groups (n=7), and CHF-parameters were measured before and after ASV treatment. Improvement was noted for the NYHA class in the ASV group but not in the non-ASV group. In contrast to the non-ASV group, the level of brain natriuretic peptide (BNP), ejection fraction, and hs-CRP levels in the ASV group significantly improved (BNP, 212.1 ± 181.2 to 77.3 ± 54.0 pg/ml [P<0.05]; ejection fraction, 43.5 ± 6.4 to 53.3 ± 6.1% [P=0.002]; hs-CRP, 0.85 ± 0.58 to 0.21 ± 0.19 mg/dl, [P=0.008]). The increase in ejection fraction was correlated with a decrease in the hs-CRP level (r=-0.753, P=0.001). CONCLUSIONS: Anti-inflammatory effects of ASV are important contributors for improving cardiac function in patients with CHF accompanied by SDB.
