Temporal artery biopsy: a diagnostic tool for systemic necrotizing vasculitis. French Vasculitis Study Group.

OBJECTIVE: To describe the clinical, biologic, and histologic features of temporal artery biopsy (TAB)-localized systemic necrotizing vasculitides (SNV), and to assess their frequency among elderly patients undergoing TAB for suspected giant cell (temporal) arteritis (GCA). METHODS: The frequency of a TAB localization of SNV was prospectively assessed in a multicenter study of elderly patients undergoing TAB for suspected GCA. All patients with SNV fulfilling the American College of Rheumatology criteria for a specific vasculitic syndrome and with evidence of vasculitis on TAB were included in a retrospective, descriptive study. RESULTS: SNV was diagnosed based on the TAB in 1.4% of the patients with suspected GCA and in 4.5% of the positive (inflamed) TAB specimens. We retrospectively selected 27 patients (18 female, 9 male; mean +/- SD age 62+/-15 years, range 22-79 years) with SNV and TAB-localized vasculitis. Only 2 of these patients were known to have SNV before TAB localization. Twenty-two patients (81%) had cephalic symptoms, including jaw claudication in 33%, clinically abnormal temporal arteries in 33%, and neuro-ophthalmologic symptoms in 11%. All patients had systemic symptoms suggestive of SNV and histologically proven NV in the TAB specimens (70%) or elsewhere in other biopsy sites (74%). Abnormal biologic results suggestive of SNV were present in 17 patients (63%). For 4 patients, the TAB-documented involvement led to initial misdiagnoses of GCA, and systemic manifestations that developed under steroid therapy revealed the correct diagnosis. The final diagnoses of the patients were polyarteritis nodosa (PAN) (n = 11), Churg-Strauss syndrome (n = 6), micropoly-angiitis (n = 3), Wegener's granulomatosis (n = 3), hepatitis B virus-related PAN (n = 2), hepatitis C virus-related cryoglobulinemic vasculitis (n = 1), and rheumatoid vasculitis (n = 1). CONCLUSION: TAB-localized SNV presents a major diagnostic dilemma because it can mimic GCA. Careful analysis of clinical, biologic, and histologic data should lead to the correct diagnosis and help guide the clinician's choice of appropriate therapy.

Serial measurements of antineutrophil cytoplasmic autoantibodies in patients with systemic vasculitis.

PURPOSE: To assess the value of serial determinations of antineutrophil cytoplasmic autoantibodies (ANCA) for monitoring disease activity in patients with systemic vasculitis. PATIENTS AND METHODS: Forty-three patients with histologically proven vasculitis (21 with Wegener's granulomatosis, 17 with microscopic polyangiitis, and 5 with renal-limited vasculitis) were studied for a median follow-up of 22 months. Disease activity was prospectively assessed and quantified by the Birmingham Vasculitis Activity Score. A total of 347 sera were analyzed for ANCA determination. RESULTS: Relapses occurred in 23 (54%) of 43 patients. Diagnostic category (Wegener's granulomatosis vs micropolyangiitis and renal-limited vasculitis), severity of initial symptoms (mean vasculitis activity score, mean number of organs involved), and ANCA pattern [cytoplasmic-ANCA (c-ANCA) vs perinuclear-ANCA (p-ANCA)] did not significantly differ between relapsers and nonrelapsers. Lung involvement was more frequent at onset among relapsers [16 of 23 (70%) vs 6 of 20 (30%); P = 0.02]. Relapses were slightly, but not significantly, more frequent in patients with Wegener's granulomatosis or a c-ANCA pattern. The percentage of relapsers was greater in patients with persistently positive ANCA than in patients with negative or decreasing ANCA titers (86% vs 20%, P = 0.0001). However, the predictive value of an increase in ANCA titers for the occurrence of a subsequent relapse was only 28% (4 of 14) for c-ANCA, 12% (2 of 17) for anti-proteinase 3-ANCA, and 43% (6 of 14) for anti-myeloperoxidase-ANCA. An increase in ANCA occurred before or during relapse in 33% (10 of 30) of cases for c-ANCA/anti-proteinase 3 antibodies, and 73% (11 of 15) of cases for anti-myeloperoxidase antibodies. CONCLUSION: The persistence of ANCA positivity is strongly associated with relapses. However, an increase in ANCA titers has a poor value for the early prediction of a subsequent relapse and should not be used as a sole parameter for therapeutic intervention. In addition, our results suggest that serial anti-myeloperoxidase determination may be useful as a prognostic marker in patients who are p-ANCA positive.

[Low prevalence of anti-annexin V antibodies in antiphospholipid syndrome with fetal loss].

PURPOSE: Annexin V, a protein with potent anticoagulant activity has a calcium-dependent binding affinity for phospholipids. Annexin V is distributed in many organs, especially in the placenta and endothelium. Various studies have shown that placental annexin V is decreased in women with anti-phospholipid syndrome. It has been suggested that annexin V might be a target of anti-phospholipid antibodies and that the subsequent decrease in annexin V might be associated with obstetrical complications. We investigated the presence of anti-annexin V antibodies in the plasma of women with anti-phospholipid syndrome and obstetrical complications. METHODS: Twenty-three patients with at least one spontaneous abortion were included in the study. Anti-cardiolipin antibodies and lupus anticoagulant were present in 87% and 30% of the patients, respectively. A group of 40 healthy women were included in the control group. Anti-annexin V IgG and IgM antibodies were measured by ELISA. RESULTS: The IgG mean OD was 0.07 +/- 0.013 in patients and 0.042 +/- 0.06 in the control group. There was no significant difference between the two groups (P = NS). Only two out of the 23 patients and two out of the 40 healthy women were positive for IgG (OD > 0.25). The sensitivity of the assay was poor (8.7%). Even when the threshold was adjusted according to the mean OD in control subjects +2 SD, the sensitivity was still poor, reaching only 13%. CONCLUSION: The prevalence of anti-annexin V was low in patients with anti-phospholipid syndrome and repetitive spontaneous abortions. Anti-annexin V assay does not appear to be sensitive enough for the identification of anti-phospholipid antibodies that might be involved in the decrease in annexin V leading subsequently to thrombosis risk.

[Prevalence of antiphospholipid antibodies in Horton's disease and in polymyalgia rheumatica].

PURPOSE: Antiphospholipid antibodies (APL) are frequently observed in the course of giant cell arteritis and polymyalgia rheumatica. However, their role and relationships with potential ischemic events are still debated. METHODS: To determine the prevalence of APL in relation with ischemic events, 62 patients with giant cell arteritis and/or polymyalgia rheumatica were retrospectively studied. RESULTS: Before corticosteroid treatment 41% of the 51 patients with giant cell arteritis and 64% of the 11 patients with isolated polymyalgic rheumatica had high IgG ACL levels, with a frequency significantly higher than that (15.6%) of the control group which was composed of healthy elderly. IgM ACL were found in only two patients with giant cell arteritis. There was no correlation between the occurrence of an ischemic event (22 ischemic events in the 51 patients with giant cell arteritis) and the presence of ACL, even though the latter were more frequently observed in the giant cell arteritis group (52% versus 41% in non ischemic patients). The prevalence of ACL increased, reaching 59% if lupus anticoagulant was associated, but the difference was not significant. ACL disappeared soon after corticosteroid therapy had been initiated. CONCLUSION: Though ACL are frequently seen in giant cell arteritis and/or polymyalgia rheumatica, they are not related to ischemic events and disappear rapidly after corticosteroid treatment.

Influence of age on characteristics of polymyositis and dermatomyositis in adults.

In a retrospective study of 79 consecutive patients, we evaluated characteristics of polymyositis (PM) and dermatomyositis (DM) and compared clinical presentation, biochemical findings, histologic changes, evolution, complications, and mortality rate of elderly patients (aged > or = 65 yr) and younger patients (aged < or = 64 yr) at the onset of PM/DM. We found a high prevalence of PM/DM in elderly patients: 23 patients (29%) were aged 65 years or over. We also found that esophageal involvement (34.8% versus 16.1%, respectively) and bacterial pneumonia related to both ventilatory insufficiency and esophageal impairment (21.7% versus 5.4%, respectively) were more common in elderly patients compared with younger patients, resulting in increased morbidity and mortality rates. Moreover, malignancy frequency was higher in elderly patients compared with younger patients (47.8% versus 9.1%, respectively, p = 0.0001), particularly patients with DM (10/11). Fifty percent of malignancies were colon malignancies in elderly patients. Erythrocyte sedimentation rate, C-reactive protein, fibrinogen, and ferritin levels were also higher in the elderly patient group compared with the younger group, and the presence of serum hypoprotidemia, hypoalbuminemia, and anemia was more frequent. Finally, PM/DM complete remission was less frequent (13.6% versus 41.1%) and the mortality rate (47.8% versus 7.3%) was higher in elderly patients than in younger patients. The main causes of death in elderly patients were bacterial pneumonia, due to ventilatory insufficiency and esophageal impairment, and malignancies. Our findings therefore indicate that PM/DM-related esophageal and lung involvement should be systematically searched for in elderly patients. Esophageal manometry and pulmonary function tests should become an integral part of initial evaluation in elderly patients for early detection of impairment. Moreover, as we observed a marked overrepresentation of colon cancer in elderly patients with DM, we suggest that the search for malignancies in elderly patients with DM should include lower gastrointestinal tract investigations.

Evaluation of the efficacy of etidronate therapy in preventing glucocorticoid-induced bone loss in patients with inflammatory rheumatic diseases. A randomized study.

The prevention and treatment of glucocorticoid-induced osteoporosis is a major concern for rheumatologists since inflammatory joint disease is among the most common reasons for long-term glucocorticoid therapy. We used a randomized placebo-controlled design to evaluate the efficacy of one-year cyclical etidronate therapy in preventing bone loss in 83 glucocorticoid-treated patients with rheumatoid arthritis, polymyalgia rheumatica, or giant cell arteritis. Glucocorticoid treatment duration was shorter than three months, and the starting dose was greater than 7.5 mg of prednisone-equivalent per day. Etidronate was given according to the standard cyclical schedule, i.e. 400 mg/d for periods of 14 days separated by 76-day intervals during which patients took 500 mg of supplemental calcium per day. The primary evaluation criterion was the change in lumbar spine bone mineral density after one year of etidronate therapy. Bone mineral density decreased by 1.94 +/- 0.61% in the placebo group and increased by 0.86 +/- 0.6% in the etidronate group, yielding a between-group difference of 2.8 +/- 0.86% (P = 0.002). The difference was largest in postmenopausal women (3.38 +/- 1.11%; P = 0.004). At the femoral neck, there was a smaller bone mineral density decrease in the etidronate than in the placebo group, but the difference (1.11 +/- 1.13%) was not statistically significant. The most common side effects were gastrointestinal symptoms and showed no difference between the two groups. Four fractures (including one vertebral fracture) occurred in the placebo group versus two (including one vertebral) in the etidronate group. Etidronate prevents glucocorticoid-induced lumbar spine bone loss in patients with rheumatoid arthritis, polymyalgia rheumatica, or giant cell arteritis.

Intravenous immunoglobulins as treatment of life threatening esophageal involvement in polymyositis and dermatomyositis.

Esophageal involvement is considered a major cause of morbidity and an indicator of poor prognosis in polymyositis (PM) and dermatomyositis (DM). We describe 3 patients with steroid resistant PM/DM with life threatening esophageal involvement, resulting in impossible oral feeding and enteral nutrition with a gastric tube. All patients had both dramatic and rapid improvement of all clinical manifestations after initiation of intravenous immunoglobulin (IVIG) therapy. Swallowing disorders completely disappeared after the second infusion of IVIG, which permitted normal oral feeding and ablation of the gastric tube. Our findings suggest IVIG should be considered the treatment of choice in such cases.

Longitudinal determination of antiphospholipid antibodies in lupus patients without previous manifestations of antiphospholipid syndrome. A prospective study.

OBJECTIVE: To investigate whether serial anticardiolipin determination contributes to the clinical management of patients with systemic lupus erythematosus (SLE) with no previous sign of the antiphospholipid syndrome (APS). METHODS: In 90 patients with SLE with no previous clinical manifestations of the APS, repeated clinical evaluations were performed, and serial blood samples (obtained over a 30 month period, range 13-53 mo) were screened for antiphospholipid antibodies (aPL). Anticardiolipin antibodies (aCL) were detected using an ELISA and considered positive if the result was >25 GPL on 2 separate occasions. Patients were not required to be on a specific treatment regimen during the study. RESULTS: Thirty-four patients (37%) had at least one positive ELISA and 11 (11/90, 12%) 2 positive ELISA for IgG aCL during the study. Lupus anticoagulant (LAC) was found in 16 patients, and a false positive VDRL in 5. At study completion, the total number of clinical or laboratory events associated with APS was 30. In univariate analysis, aCL was significantly associated only with LAC (p<0.012). Presence of aCL also correlated with hemoglobin level, anti-DNA antibody, leukocyte count, and the SLE Disease Activity Index (SLEDAI). LAC and aCL were significantly associated with each other (OR 5.17; 95% CI 1.5-17.7), but LAC had a better positive predictive value than aCL for arterial thrombosis and neurological events. CONCLUSION: Among our patients with SLE without previous clinical manifestations of APS, positive aCL did not predict the occurrence of APS within the next 3 years, but was statistically related to the clinical disease activity (SLEDAI).

[Raynaud's phenomena of occupational origin].

Raynaud's phenomenon must systematically lead to the research of a professional cause, mainly if the patient is a manual worker. The most frequent professional cause is vibrations disease which involves different occupations, especially woodcutters. In this disease, Raynaud's phenomenon may be associated with neurological or rheumatic manifestations. Prevention relies on tool improvement and reduction of exposure-time. The more uncommon hammer's syndrome is characterized by the onset of a terminal cubital artery aneurysm, resulting from repeated trauma on the palm of the hand. Raynaud's phenomenon is severe, with frequent trophic complications related to embolic migration towards digital arteries. Improved prevention explains that acrosyndromes related to vinyl chloride exposure are now very rare. Finally, a Raynaud's phenomenon may be the first symptom of a systemic sclerosis induced by silicate exposure.

[Lymph node tuberculosis in France in non-immunosuppressed adults: current pathology].

PURPOSE: Lymph node tuberculosis is more frequent in Africa or in HIV-infected patients. METHODS: We review results that were obtained in 18 patients with lymph node tuberculosis but without infection by HIV. Eight French native patients (mean age: 69 years) and ten African patients (mean age: 32.5 years) were included into the study. RESULTS: Of the 18 patients, 14 had exclusively hematopoietic localizations, two with medullar involvement and two with either liver or spleen involvement. Normal erythrocyte sedimentation rate was found in two out of 18 cases and normal C-reactive protein levels in seven out of 17 cases. Lymph node biopsy revealed lesions typically associated with tuberculosis in 12 out of 14 patients, two of them had no necrosis. Inflammatory syndrome was inconstant, tuberculin test sometimes negative. A favorable outcome was seen in all cases after 6, 12 or 18 months of treatment, depending on clinical appreciation. CONCLUSION: Tuberculous lymphadenopathy in non-HIV-infected patients may occur without inflammatory syndrome, with sometimes negative tuberculin test and without lymph node necrosis.
