Polyarthritis with perinuclear antineutrophil cytoplasmic antibody and Pyoderma gangrenosum. Report of a case.

The authors report a case of Pyoderma gangrenosum with seronegative nondestructive polyarthritis and perinuclear antineutrophil cyoplasm antibody. Rheumatic disorders that occur in association with Pyoderma gangrenosum are reviewed. The constellation of manifestations in the authors' patient does not have been reported previously and may represent a new entity among the rheumatic manifestations of Pyoderma gangrenosum.

No link between avascular necrosis of the femoral head and antiphospholipid antibodies.

The rate of occurrence of antiphospholipid antibodies was compared in 47 patients with avascular necrosis of the femoral head and in 47 controls matched on age and sex. Antiphospholipid antibodies were looked for using three techniques in each patient, namely the VDRL test, an ELISA for anticardiolipin, and a circulating anticoagulant detection procedure involving three different tests. The VDRL and the tests for circulating anticoagulants were negative in all the patients and controls. No significant between-group difference was found for the ELISA, which was positive in three patients and two controls.

Secretory phospholipase A2 generates the novel lipid mediator lysophosphatidic acid in membrane microvesicles shed from activated cells.

Nonpancreatic secretory phospholipase A2 (sPLA2) displays proinflammatory properties; however, its physiological substrate is not identified. Although inactive toward intact cells, sPLA2 hydrolyzed phospholipids in membrane microvesicles shed from Ca(2+)-loaded erythrocytes as well as from platelets and from whole blood cells challenged with inflammatory stimuli. sPLA2 was stimulated upon degradation of sphingomyelin (SPH) and produced lysophosphatidic acid (LPA), which induced platelet aggregation. Finally, lysophospholipid-containing vesicles and sPLA2 were detected in inflammatory fluids in relative proportions identical to those used in vitro. We conclude that upon loss of phospholipid asymmetry, cell-derived microvesicles provide a preferential substrate for sPLA2. SPH hydrolysis, which is provoked by various cytokines, regulates sPLA2 activity, and the novel lipid mediator LPA can be generated by this pathway.

Symptomatic osteonecrosis in recipients of nonautologous bone marrow transplants.

A retrospective study of 36 allogeneic bone marrow transplant recipients was conducted to determine the rate of occurrence of and risk factors for avascular osteonecrosis. Eight patients developed osteonecrosis, after a mean time interval of 18 months. Multiple sites were often involved (mean 2.37 per patient). Advanced roentgenologic lesions were present at diagnosis in most instances. The occurrence of osteonecrosis was not significantly correlated with the initial hematologic diagnosis, the preparative regimen, serum lipid abnormalities, presence of acute or chronic graft-versus-host disease, or corticosteroid therapy characteristics. Intraosseous blood vessels exhibited histologic lesions consistent with a role of graft-versus-host-disease vasculitis in the occurrence of osteonecrosis in nonautologous bone marrow transplant recipients.

Immunoblotting detection of so-called 'antikeratin antibodies': a new assay for the diagnosis of rheumatoid arthritis.

OBJECTIVES: To assess the diagnostic value for rheumatoid arthritis (RA), of an immunoblotting assay based on the rat oesophagus epithelium antigens recognised by the so-called 'antikeratin antibodies' ('AKA'), antigens that have been identified as three non-cytokeratin proteins (referred to as A, B and C proteins). METHODS: After polyacrylamide gel electrophoresis in non-denaturing conditions and electrotransfer of an epithelial extract, the immunoreactivities to the A, B and C proteins of a series of serum samples from 88 patients with RA and 100 patients with non-rheumatoid rheumatic diseases, were semiquantitatively evaluated. RESULTS: A total of 81.8% of RA serum samples recognised the three proteins, while 91% of non-RA serum samples only weakly recognised the A and B proteins but not the C protein. Only in the group of RA patients, were the titres of the antibodies to the A, B and C proteins found to be significantly correlated with each other and with the titres of 'AKA' detected by the standard indirect immunofluorescence (IIF) method. For a diagnostic specificity of 99%, the diagnostic sensitivities of the detection of the A and B proteins were 50% and 43.2%, respectively, when those of the detection of 'AKA' by IIF and of IgM-rheumatoid factor by enzyme-linked immunosorbent assay were 42% and 54%, respectively. In contrast, at a same specificity of 99%, the diagnostic sensitivity of the detection of the C protein was significantly higher with a value of 70.5%. CONCLUSION: This immunoblotting assay which is the first immunochemical method proposed for the detection of 'AKA, should be validated on larger series of patients but can already be considered as a very powerful test for the serological diagnosis of RA.

[Treatment of Horton disease. Value of synthetic antimalarials. Apropos of a retrospective study of 36 patients].

Thirty-six patients with giant cells arteritis were studied retrospectively. Histological examination of the temporal artery or another artery was positive in 95% of cases. Mean follow-up was five years. A synthetic antimalarial was used in every case. Two groups were differentiated. One (Group I) was composed of 21 patients who were given the antimalarial drug as part of the first-line therapy, either with a corticosteroid in a mean dose of 36 mg/d (18 patients) or with a nonsteroidal antiinflammatory agent. The other group (Group II) included 15 patients in whom the antimalarial was used after a period of corticosteroid therapy, because of steroid-dependency (n = 5) or adverse effects (n = 9), or as part of a routinely used protocol (n = 1). Withdrawal of the corticosteroid was achieved in 81% of cases, after a mean interval of 15 months. Many patients discontinued the corticosteroid after less than one year. The 18 Group I patients who were given a corticosteroid were all able to discontinue this drug. The overall recovery rate was 58%; mean time to recovery was 33 months with a mean follow-up of 52 months. There were no recurrences at discontinuation of the treatment. Adverse effects of antimalarial therapy were recorded in 30.5% of patients and required discontinuation of the drug in 19%. The most often used regimen was hydroxychloroquine (40 mg/d) for at least two years and prednisone 20 to 30 mg/d for two months, in the absence of vascular complications.(ABSTRACT TRUNCATED AT 250 WORDS)

[Rheumatologic aspects of toxocariasis (visceral Larva migrans). Apropos of 2 cases].

Visceral Larva migrans is a human infection by the larvae of dog ascarids or, more rarely, ascarids of other animal species. It is endemic in France. Two cases which respectively manifested as acute oligoarthritis and inflammatory myalgia with increased muscle enzyme levels are reported. Manifestations of the minor forms of this infestation are reviewed.

[Magnetic resonance imaging in osteoid osteoma].

The purpose of this study was to determine magnetic resonance imaging (MRI) features of osteoid osteomas and to evaluate the place of MRI in the diagnostic workup of suspected osteoid osteoma by comparing its diagnostic value with that of computed tomography (CT). Nine patients with radioclinical features highly suggestive of osteoid osteoma were investigated using bone scintigraphy, CT scan and MRI. MRI sequences were weighted for T1 (TR: 500 ms-TE: 34 ms), T2 (TR:2000 ms-TE:50-100 ms) and T1 after intravenous injection of gadolinium-DTPA contrast material. The appearance of the nidus and surrounding area were analyzed, as well as the accompanying inflammatory reaction involving the bone marrow, soft tissues or synovium. All patients had surgical treatment. Clinical recovery was achieved in every case. Histological studies confirmed the diagnosis of osteoid osteoma in 7 patients. In two cases, histological confirmation was not obtained and the exact nature of the lesion therefore remained in doubt, although clinical and scintigraphic findings as well as the subsequent course were consistent with the diagnosis of osteoid osteoma. In 5 cases, MRI proved inferior to CT scan for detecting the nidus. MRI disclosed edema of the bone marrow not seen on CT scan sections in 5 cases, edema of the soft tissues in three cases, and synovitis with joint effusion in one patient with an epiphyseal osteoid osteoma. At present, MRI plays only an ancillary role in the diagnosis of osteoid osteoma, which rests on the concomitant use of bone scintigraphy and CT scan.(ABSTRACT TRUNCATED AT 250 WORDS)
