Proteinase-3 (PR3) is an abundant serine proteinase stored in the azurophilic granules of neutrophils and released to the cell surface upon activation where it contributes to local tissue destruction and inflammation. The sub-population of membrane PR3 (mPR3) high expression (PR3-high) varies among individuals. There are many reports about PR3 in Wegener's granulomatosis, but few about PR3 expression in patients with common inflammatory disorders, such as sepsis. The mPR3 expression on neutrophils from 56 patients with inflammatory disorders and from 64 healthy volunteers was examined by flow cytometry. High variability in the percentage of PR3-high (%PR3-high) neutrophils was observed in healthy volunteers and patients with inflammatory disease, and the %PR3-high was significantly greater in the patients (72 +/- 19% vs 55 +/- 20%, P < 0.0001). Overall neutrophil PR3 expression in patients with infectious diseases, especially systemic inflammatory response syndrome (SIRS) was significantly high (P < 0.01) and showed a positive correlation with C-reactive protein (CRP). Even under inflammatory conditions not involving autoimmune vasculitis, there are significant increases in both the absolute surface expression of PR3 and the numbers of neutrophils expressing high levels of PR3 and these correlate with CRP levels. The data are consistent with a model in which neutrophil membrane expression of PR3 is greatly influenced by an in vivo inflammatory environment.

We report to simultaneous use of extracorporeal life support (ECLS), plasmapheresis, hemodiafiltration and exogenous surfactant for the treatment of pulmonary hemorrhage, arterial hypertension, and renal failure secondary to nodose polyarteritis (NPA) in a 23-month-old patient. NPA is an autoimmune disease that affects small -and medium- caliber muscular arteries. Hypoxemia refractory to treatment with conventional and high frequency oscillatory ventilation was supported by ECMO while awaiting control of the autoimmune disease through the use of plasmapheresis and immunosuppressive treatment. Although the combination of ECLS with plasmapheresis is rare, it has been described during the management of cases of organ transplant, intoxication, cardiac failure, and sepsis. There are only two previous reports describing the use of this combined therapy for the treatment of pulmonary hemorrhage secondary to autoimmune vasculitis in childhood.

Internal jugular vein thrombosis is a rare critical cardiovascular emergency, which has potential catastrophic clinical outcomes by resulting in stroke and pulmonary embolism. Several etiologies have been reported; however, there are limited data on Lemierre's and Trousseau's syndromes, which are both rare conditions with advanced disease progression and poor clinical outcomes. Lemierre's syndrome may present with typical progressively infectious symptoms and signs, including sore throat, neck mass, and fever, whereas Trousseau's syndrome may present with thrombophlebitis and painful edema. Without antibiotic agents controlling the infection, the condition of patients with Lemierre's syndrome may progress to sepsis or septic shock. The infection pattern plays an important role for differential diagnosis. Herein, we describe the case of a 46-year-old woman presenting with atypical symptoms of Trousseau's syndrome mimicking Lemierre's syndrome. Laboratory analysis including protein C, protein S, rheumatoid factor, and antinuclear antibody ruled out hypercoagulopathy and autoimmune vasculitis. Abdominal computed tomography and panendoscopy revealed ulcerative tumor at the antrum. Pathological examination confirmed the presence of signet-ring cell adenocarcinoma. We highlight the clinical features and etiologies of internal jugular vein thrombosis, especially in Lemierre's syndrome and Trousseau's syndrome, to aid physicians in making an early diagnosis and providing timely management.
