Long term effectiveness of intravenous immunoglobulin in Churg-Strauss syndrome.
(57/216)
OBJECTIVE: To study the long term effectiveness of intravenous immunoglobulin and plasmapheresis associated with prednisone and cyclophosphamide in Churg-Strauss syndrome. SUBJECTS: and methods: We studied 18 subjects with new onset Churg-Strauss syndrome. All received the "standard" treatment based on prednisone (1 mg/kg/day for 1 month and then slowly tapered) and cyclophosphamide (2 mg/kg/day for 6 months in severe cases). In nine patients, synchronised cycles with plasmapheresis and intravenous immunoglobulin (2 g/kg) were repeated monthly for 6 months and every other month for a further three cycles. Clinical (disease activity monitored by Birmingham vasculitis activity score (BVAS) and damage index (modified Rankin score)) and functional (C reactive protein, blood eosinophil count, and electromyogram-electoneurogram) parameters were collected during treatment and the 3 year follow up period. RESULTS: After 12 months, all patients in the treatment group and four (44%) in the control group were in remission. At the end of the 3 year follow up period, we documented significant differences in BVAS (p<0.01), global damage (p<0.02), modified Rankin score (p<0.04), and the daily maintenance prednisone dose (p<0.002) between the two groups. We found a tendency towards lower frequency of relapse and incidence of osteoporosis in the treatment group. CONCLUSION: Complete clinical and functional recovery with a long term stable remission and a low incidence of side effects can be achieved by intravenous immunoglobulin associated with plasmapheresis in patients with Churg-Strauss syndrome.

Primary systemic vasculitis: clinical features and mortality.
(58/216)
BACKGROUND: Wegener's granulomatosis (WG), Churg Strauss syndrome (CSS) and microscopic polyangiitis (MPA) are primary systemic vasculitides (PSV), the clinical features of which have been described from tertiary centres. AIM: To provide the first clinical description of MPA from a general hospital and compare clinical features with WG and CSS. DESIGN: Retrospective analysis of patient records. METHODS: Records of 99 PSV patients attending a single hospital, from 1988 to 2000, were reviewed for: clinical features, date/age at diagnosis, sex, duration of illness, anti-neutrophil cytoplasmic antibodies (ANCA), treatment, comorbidity and deaths. Cases were classified using ACR, CHCC and Lanham criteria/definitions. Birmingham vasculitis activity scores (BVAS) and damage index (VDI) were calculated. Survival was assessed using Cox proportional hazards model and standardized mortality ratios (SMRs). RESULTS: Compared to previous reports there was more ENT (29%) and respiratory (29%) but less renal (92%) involvement in MPA, and less ENT involvement in WG (81%). CSS showed high neurological (72%), cardiovascular (28%) and gastrointestinal (17%) involvement and the highest median (range) VDI (p = 0.01 vs. WG; p = 0.001 vs. MPA). BVAS1 was significantly lower in MPA than in WG [median (range) 15 (4-29) vs. 21 (6-39), (p = 0.001)] but not in CSS [20 (7-28), p = 0.08]. SMR (95%CI) for PSV was 4.8 (3.0-6.6); 5-year survival was 45.1% for MPA, 75.9% for WG and 68.1% for CSS. Age was a significant risk, but only to the same extent as in the reference population. When age was adjusted for, no other significant factor was found. DISCUSSION: The clinical characteristics seen here are similar to those in previous series. There are difficulties in using the MPA CHCC definitions in classification. There is a high proportion of neurological involvement in CSS, causing permanent damage. MPA may have a poorer prognosis than WG or CSS. (+info)
Stable incidence of primary systemic vasculitides over five years: results from the German vasculitis register.
(59/216)
OBJECTIVE: To register all newly diagnosed patients with primary systemic vasculitides (PSV) in a large region in northern Germany. METHODS: Between January 1, 1998 and December 31, 2002 all newly diagnosed cases of PSV were identified in a large mixed rural/urban northern German region consisting of 2,777,275 habitants in a population-based prospective study. The following sources were used: departments of all hospitals, including their outpatient clinics; all departments of pathology; and the reference immunologic labs serving the catchment area. RESULTS: During 5 years, 642 PSV patients were identified. The incidence rates for all PSV were between 40 and 54 cases per 1 million and per year. People at age 50 years and older had a 3-5-fold higher risk of developing PSV compared with those younger than 50 years. The incidence rates of antineutrophil cytoplasmic antibody (ANCA)-associated PSV (Wegener's granulomatosis [WG], microscopic polyangiitis [MPA], Churg-Strauss syndrome [CSS]) were between 9.5 and 16/million/year. WG occured 2-3 times more frequently than MPA or CSS. CONCLUSION: Results of a population-based vasculitis register over 5 years for the incidence of PSV among 2.78 million habitants in northern Germany revealed a stable incidence for all PSV. Compared with other European studies coming from small regions or referral centers, the incidence rates for ANCA-associated PSV were the same as in Norway, lower than those in United Kingdom, but higher than those in Spain.

Clinical review: Vasculitis on the intensive care unit -- part 2: treatment and prognosis.
(60/216)
The second part of this review addresses the treatment and prognosis of the vasculitides Wegener's granulomatosis, microscopic polyangiitis, Churg-Strauss syndrome and polyarteritis nodosa. Treatment regimens consist of an initial remission phase with aggressive immunosuppression, followed by a more prolonged maintenance phase using less toxic agents and doses. This review focuses on the initial treatment of fulminant vasculitis, the mainstay of which remains immunosuppression with steroids and cyclophosphamide. For Wegener's granulomatosis and microscopic polyangiitis plasma exchange can be considered for first-line therapy in patients with acute renal failure and/or pulmonary haemorrhage. Refractory disease is rare and is usually due to inadequate treatment. The vasculitides provide a particular challenge for the critical care team. Particular aspects of major organ support related to these conditions are discussed. Effective treatment has revolutionized the prognosis of these conditions. However, mortality is still approximately 50% for those requiring admission to intensive care unit. Furthermore, there is a high morbidity associated with both the diseases themselves and the treatment. (+info)
Churg-Strauss syndrome associated with HIV infection.
(61/216)
A 28-year-old woman with a history of asthma and recent deep venous thrombosis presented with fever, chest pain, and peripheral eosinophilia. The patient was subsequently diagnosed with Churg-Strauss syndrome and HIV infection, representing to our knowledge only the second case of this association. Rheumatologic manifestations of HIV may precede clinical signs of infection. This is significant because steroidal and cytotoxic therapy may potentially worsen HIV infection. As the prevalence of HIV infection rises, there may be atypical presentations of various rheumatologic syndromes. The following case demonstrates a patient whose initial presentation for HIV infection was Churg-Strauss syndrome. (+info)
Churg-Strauss syndrome associated with hypersensitivity to acetaminophen.
(62/216)
Acetaminophen is a widely used antipyretic drug. We describe a 64-year-old Japanese woman who developed typical Churg-Strauss syndrome after frequent use of acetaminophen. Following the ingestion of acetaminophen, she exhibited various allergic reactions such as asthmatic attacks, pyrexia and petechiae on legs. In the lymphocyte transformation test, a positive reaction to acetaminophen was detected. A muscle biopsy revealed massive extravascular eosinophil infiltration and a necrotizing vasculitis. Hypersensitivity to acetaminophen may be implicated in the development of Churg-Strauss syndrome in this case. (+info)

An autopsy case of isolated eosinophilic coronary periarteritis: a limited form of Churg-Strauss syndrome or a new entity?
(64/216)
A 52-year-old man without a history of asthma or allergic diseases died of ventricular fibrillation early in the morning. His autopsy revealed no significant findings, except for a mild mural-thickening localized at the proximal region of the right coronary artery. Microscopic examination showed periarteritis with infiltration of numerous eosinophils in the adventitia. No significant vasculitis was found in any other organs. Based on the findings this seems to be the second reported case of isolated eosinophilic coronary periarteritis. (+info)
