This study was conducted to determine the frequency, severity and outcome of cardiac findings in patients with acute Puumala hantavirus-induced nephropathia epidemica (NE). 70 consecutive, hospital-treated patients with serologically confirmed NE were prospectively examined using serial electrocardiograms (ECG), plasma troponin I, tumour necrosis factor alpha (TNF-alpha), interleukin-6 (IL-6), and echocardiography (ECHO). Examinations were repeated after 3 and 12 months. ECG changes were observed in 57% of patients. Plasma troponin I levels remained normal in all. In six patients, ECHO showed left ventricular contraction abnormalities, and 1 patient had mild pericardial effusion. There were no differences in clinical or standard laboratory findings or in plasma TNF-alpha and IL-6 concentrations between patients with and without ECG or ECHO changes. During the follow-up, all acute-phase changes in ECG and ECHO reverted to normal, which probably reflects their benign nature. We conclude that abnormal cardiac findings are surprisingly common during NE.

We report a 60-year-old woman with rheumatoid arthritis complicated by pericarditis. Treatment with tocilizumab improved her polyarthritis, but the pericardial effusion increased so rapidly as to cause cardiac tamponade before the treatment could prove its efficacy. Pericardial effusion disappeared after pericardiocentesis. The pericardial fluid contained a remarkably high concentration of interleukin-6 (IL-6; 351,000 pg/mL), which tocilizumab appeared to have made yet higher compared to the reported IL-6 levels in rheumatoid pericarditis. No further exacerbation of pericarditis was observed after retreatment with tocilizumab. This case has important implications in that it suggests that the prominently elevated IL-6 level in pericardial fluid during tocilizumab treatment may be an indicator of its efficacy for pericarditis.

A 51-year-old Japanese woman developed systemic lupus erythematosus (SLE) in 1995. In August 2005, she had massive pericardial effusion due to lupus pericarditis, which was compromising her circulation. Methylprednisolone pulse, intravenous cyclophosphamide pulse and pericardiocentesis were all ineffective. The pericardium was cut surgically to create a passage to drain the liquid into the pleural cavity. The procedure was temporarily effective; however, massive liquid accumulated in the pleural cavity within 1 year. Oral tacrolimus and topical betamethasone injection were ineffective. Since the interleukin-6 (IL-6) level in the effusion was markedly increased (1160 pg/ml), tocilizumab was administered intravenously at a dose of 8 mg/kg every 4 weeks. The effect was astonishing and only a residual amount of pericardial effusion remained. Prednisolone was tapered successfully from 15 to 5 mg daily. Tocilizumab is a treatment of choice when we confront an intractable serositis with massive effusion in SLE, if the IL-6 level is high.

Acute pericarditis is inflammation of the pericardium with or without pericardial effusion. In the pediatric population, most patients with acute pericarditis are diagnosed with idiopathic pericarditis. Herein, we present two children with idiopathic pericarditis who underwent immunological assessment of pericardial effusion for the first time. Both patients showed equally high levels of interleukin-6 in the pericardial effusion. However, they had different treatment responses, in accordance with the pericardial effusion and serum interleukin-10 concentrations. Our present cases suggest that interleukin-10 may be associated with the response to anti-inflammatory therapy in idiopathic acute pericarditis.
