Sustained benefit in rheumatoid arthritis following one course of rituximab: improvements in physical function over 2 years.

OBJECTIVES: To evaluate the long-term impact on physical function of a single course of rituximab in rheumatoid factor, seropositive patients with active rheumatoid arthritis (RA) despite ongoing methotrexate treatment. METHODS: A randomized, controlled trial comparing rituximab alone [1,000 mg intravenously (iv) on days 1 and 15, n= 40], or in combination with cyclophosphamide (750 mg iv on days 3 and 7, n= 41) or oral methotrexate (> or =10 mg/week, n= 40) with placebo + methotrexate (> or =10 mg/week, n= 40), resulted in significant reductions in disease activity at weeks 24 and 48. Sustained improvements in physical function and standard effect sizes (SES) for changes in components of ACR and EULAR criteria were evaluated over 2 yrs. RESULTS: More patients receiving rituximab + methotrexate completed a 2-yr follow-up without further treatment than those receiving placebo + methotrexate (45% vs 15%, respectively), rituximab alone (10%) or rituximab + cyclophosphamide (22%). This reflected a higher percentage of patients receiving rituximab + methotrexate reporting improvements in Health Assessment Questionnaire Disability Index > or = minimum clinically important difference at 1 and 2 yrs (68% and 30%, respectively) compared with placebo + methotrexate (28% and 15%), rituximab monotherapy (43% and 10%) or rituximab + cyclophosphamide (39% and 12%). SES were high in all rituximab groups and revealed differing patterns of response over time. CONCLUSION: A single course of rituximab with continuing methotrexate in patients with active RA provided clinically meaningful improvements in physical function over 2 yrs, with lower discontinuation rates and larger SES for improvements in ACR and EULAR criteria components.

Anterior sonography of glenohumeral joint in patients with inflammatory joint disease.

Ultrasonography (US) was shown as an effective imaging modality in evaluating the shoulder. The shoulder joint is probably the most accessible joint for sonography in adults. However, inflammatory changes of the shoulder have received too little attention in US studies. Anterior access for US assessment of glenohumeral joint (GHJ) has not been investigated. Another problem of patients with acute synovitis of glenohumeral joint is the difficulty to perform a 90 degrees abduction for the axillary US because of severe pain and active and passive limitation. We offer the anterior access for assessment of glenohumeral joint synovitis (GHS). Sonographic evaluation (Sonosite-Titan) was carried out in 25 patients with acute GHS and 15 healthy controls. The diagnosis of GHS was made after the patients underwent physical examination and the laboratory evidence was obtained. We used the anterior position of transducer applied laterally to coracoid processus along the anterior joint cavity. The problem of anterior joint cavity investigation in neutral position is a poor presentation of the joint and the application of the biceps tendon. The problem is simply resolved after supination of the hand and external rotation of the shoulder. We measured and compared upper, middle, and lower width of the anterior GHJ cavity. Echogenicity of joint cavity was assessed by comparison with adjacent tissues. Homogeneity and regularity of GHJ cavity was designated in both groups as well. We measured labrum-infraspinatus distance on posterior view for assessment of GHJ synovitis. All cases of GHJ synovitis were confirmed by a US Doppler study. US investigation of healthy controls enabled to find normal values of the width of the anterior GHJ cavity that was less than 7.4 mm. The synovitis group showed GHJ cavity expansion: 8.3+/-2.4 (p=0.001) and 10.5+/-3.1 (p<0.001) for the middle and the lower anterior part of the GHJ respectively. The upper part width was not different in synovitis and control groups. Anterior joint cavity extension to 7.4 mm and upper in its lower part was high sensitive (96%) and specific (86%) US sign of synovitis with the test power above 0.9. The posterior labrum-infraspinatus extension had high specificity for synovitis (100%), but only seven of 25 patients (28%) had increased (>2 mm) the value of the labrum-infraspinatus dimension, which was previously proposed as the US sign of synovitis. Echogenicity of the anterior joint cavity in healthy controls was moderately high (far more echogenic than deltoid muscle). Echogenicity of synovitis declined, and mild effusions were found to be common. Those were not to be seen on US of GHJ in neutral position and were revealed only in supination and external rotation of the shoulder. Intra-articular tissue of healthy controls was relatively echo-homogenic compared with nonhomogenic one of the synovitis group. Bone irregularity was found in patients with long-standing GHJ synovitis reflecting erosive process. A certain position of the shoulder and good knowledge of the normal anterior joint cavity parameters enabled us to diagnose synovitis by anterior shoulder sonography, with the patients experiencing minimal pain during movements.

Serum-synovial gradient data of normouricemic patients with history of gout and acute knee effusion.

The etiology of arthritis episodes in normouricemic patients with gout is still unclear. We propose that the fluctuation in synovial urate level, as well as pH, ion strength, albumin, and globulin values relative to serum levels, could be involved in crystal formation. To assess serum-synovial gradient (SSG), the sera and synovial fluid (SF) of six normouricemic patients (men, age 48-79) with a history of gout (American College of Rheumatology criteria) and acute knee effusion were screened for uric acid, pH, osmolality (Osm), P/Ca, albumin, globulin, and SSG. Monosodium urate monohydrate (MSUM) crystals were determined by polarized light (PL). Infectious arthritis was ruled out via Gram staining and synovial fluid culture. Negative X-ray and PL microscopy results excluded chondrocalcinosis. Five patients (1-5) had inflammatory knee effusion (WBC >2,000/mm(3)), and one (patient 6) had noninflammatory knee effusion (600 WBC/mm(3)). MSUM crystals were found in the WBC of patient 1 only. He had tophaceous gout with normal serum uric acid levels and showed significant negative Osm and P and positive Ca SSG. Two crystal negative patients had severe negative pH SSG with alkaline synovial fluid, significant P/Ca SSG, and high positive globulin SSG, while one of them had supersaturated SF uric acid content. The other patients displayed an increased Osm and P/Ca SSG. All SSG values were five to ten times higher than the coefficient of variance for used methods. Noninflammatory SF of patient 6 does not appear to be related to active gout. The data on SSG for MSUM, pH, Osm, Alb/Glob, and P/Ca in normouricemic patients with gout history and acute knee effusion was not homogeneous. We propose that acid-base and ionic-protein gradient may lead to instability of subsaturated urate solution, thereby predisposing to MSUM deposits within synovial membrane and inducing inflammation.

Recalcitrant leg ulcer due to mixed connective tissue disease.

We present a 28-year-old woman with mixed connective tissue disease (MCTD) complicated by a recalcitrant longstanding leg ulcer, which responded to complex therapy with local polydine, systemic ciprofloxacin, iloprost, enoxaparin and aspirin. Cyclophosphamide pulse therapy and corticosteroids controlled the systemic inflammation but failed to heal the leg ulcer. We considered a rationale of complex therapy for the leg ulcer on a basis of pathogenesis and complications of MCTD.

Non-invasive measurement of biomechanical skin properties in systemic sclerosis.

OBJECTIVE: To evaluate biomechanical properties of skin in patients with systemic sclerosis (SSc) using the BTC-2000 suction device. METHODS: Twenty five patients with limited cutaneous SSc (lcSSc), 20 patients with diffuse disease (dcSSc), and 25 age matched healthy controls were evaluated. Viscoelastic deformation (VED, mm), elastic deformation (ED, mm), ultimate deformation (UD, mm), and pressure-deformation ratio (PDR, mm Hg/mm) were measured on the dorsal surface of the forearm, shoulder, and above the trapezius muscle on the back. RESULTS: Indices of skin extensibility (VED, ED, UD) were reduced and resistance to stress (PDR) increased in patients with dcSSc compared with healthy controls, or patients with lcSSc, at all three sites (p<0.001). At all sites, and overall, UD, ED, and VED were lower and PDR was higher at skin score above grade 2, compared with clinically normal skin. For both lcSSc and dcSSc biomechanical differences from controls were found even at sites of clinically normal skin. CONCLUSION: BTC-2000 is a sensitive tool for clinical evaluation of skin involvement in SSc and may be a valuable adjunct to skin sclerosis score in disease monitoring.

Cocaine-Induced raynaud's phenomenon and ischaemic finger necrosis.

A 37-year-old man with ischaemic finger necrosis and recent-onset Raynaud's phenomenon associated with cocaine abuse is reported. Initial therapy with systemic vasodilators, low-molecular-weight heparin and aspirin failed. Resolution of the ischaemia and ulcer healing was rapidly achieved with intravenous infusions of the prostacyclin analogue iloprost. The mechanism of vascular ischaemic injury and the development of secondary Raynaud's phenomenon due to cocaine use is discussed.

Arthritis related to ileal pouchitis following total proctocolectomy for ulcerative colitis.

OBJECTIVE: To draw attention to arthritis that developed in patients who underwent total proctocolectomy with ileal pouch construction for ulcerative colitis (UC). METHODS: The course of 4 patients who developed arthritis for the first time after ileal-anal pouch anastomosis is described. In addition, the relationship to the chronic inflammation of the pouch-pouchitis-is discussed. RESULTS: The clinical manifestations were very similar to seronegative arthritis affecting mainly the joints of the lower extremities. It was accompanied by enthesopathy (2 patients) and by sacroiliitis (2 patients). All had active pouchitis. The abnormal laboratory test results were nonspecific, indicating chronic inflammation. All 4 patients tested negative for human leukocyte antigen (HLA) B27, and none had other concomitant extraintestinal manifestations. Steroids rapidly improved both the arthritis and pouchitis; however, disease-modifying antirheumatic drugs were required to maintain remission with minimal daily steroids. Flares of the arthritis were always associated with active pouchitis, but the opposite was not necessarily true. CONCLUSIONS: Arthritis related to ileal pouchitis after total colectomy for UC has many similarities to the arthritis associated with inflammatory bowel disease and should be added to the list of enteropathic arthropathies.

Ticlopidine-induced lupus.

Ticlopidine is a widely used drug for prevention of stroke and other serious vascular events with a multitude of possible side effects. An increasing number of drugs are being recognized as the triggering agents of drug-induced lupus. We describe three patients in whom the etiologic connection between ticlopidine and lupus was supported by the appearance of lupus-like features (fever, rash, arthritis, renal involvement, positive antinuclear and antihistone antibodies), shortly after drug initiation, and their gradual resolution after its discontinuation. If suggested by clinical or/and laboratory findings (fever of unknown cause, musculoskeletal involvement, hematologic abnormalities), the possibility of ticlopidine-induced lupus should be taken into consideration and appropriate investigations should be performed. Patients should resolve slowly but completely after withdrawal of ticlopidine.

Naproxen-induced leukocytoclastic vasculitis.

Cutaneous reactions to non-steroidal anti-inflammatory drugs (NSAIDs) are rare in spite of their wide use. Only a few cases of hypersensitivity angiitis related to naproxen have been described. We report the case of a 62-year-old woman in whom leukocytoclastic skin vasculitis, peripheral neuropathy and nephritis developed after a short naproxen treatment, and gradually regressed after discontinuation of the drug and under glucocorticoid therapy. In the light of the relevant literature, the clinical and laboratory features of this reversible condition are described.

Inflammatory bowel disease and myositis.

A patient with Crohn's disease developed proximal muscle weakness, increased serum creatine phosphokinase activity and electromyographic abnormalities. A muscle biopsy was non-diagnostic. Although rare, myositis should be included in the differential diagnosis of muscle weakness in patients with inflammatory bowel disease.

Chronic tophaceous gouty arthritis mimicking rheumatoid arthritis.

OBJECTIVES: To analyze the factors which differentiate chronic tophaceous arthritis from rheumatoid arthritis. METHODS: We describe two cases of chronic gouty arthritis masquerading as rheumatoid arthritis. The characteristic features of each of these two conditions and the diagnostic approach are discussed in light of relevant literature. RESULTS: The correct diagnosis was reached by the combination of accurate history taking (family history of gout, alcoholism, previous diuretic therapy and renal stones), guiding clinical features (subcutaneous tophaceous deposits) and specific radiological (assymetrical erosions with sclerotic margins and overlying edges) and laboratory findings (hyperuricemia and hyperuricosuria). It was confirmed by the identification of monosodium urate (MSU) crystals in the synovial and subcutaneous tissues. CONCLUSIONS: Gout and rheumatoid arthritis rarely coexist. Chronic gouty arthritis may mimic rheumatoid arthritis, and vice-versa. Clinical suspicion supplemented by characteristic laboratory, radiological and histologic findings help at reaching an accurate diagnosis.

Primary subcutaneous nocardial infection in a SLE patient.

A patient with systemic lupus erythematosus (SLE) developed primary subcutaneous nocardiosis during steroid and cyclophosphamide therapy for diffuse proliferative glomerulonephritis. In spite of local process the patient manifested signs of general deterioration mimicking SLE exacerbation. The diagnosis was made by bacteriologic examination of the material obtained by CT guided aspiration. Surgical drainage and systemic treatment with trimethoprim/sulphamethoxazole (TMT/SMZ) 960 mg twice/d led to a clinical recovery and enabled the continuation of the steroid and cytotoxic regimen.

Seasonal distribution of relapse onset in rheumatoid arthritis and spondyloarthropathy: the possible effect of the solar factor.

BACKGROUND AND OBJECTIVE: The seasonal effect on the relapse of rheumatoid arthritis and spondyloarthropathies is still unclear. To assess the seasonal distribution of relapse onset in rheumatoid arthritis (RA) and spondyloarthropathy (SpA) and its association with solar factors. METHODS: The monthly distribution of relapse onsets during the years 1998-2000 was retrospectively chart reviewed in 364 patients. In 1998 a total of 131 patients were studied; 60 with seropositive (sp) RA, 30 with seronegative (sn) RA and 41 with SpA; 113 patients in 1999: 44 with spRA, 38 with snRA and 31 with SpA; 120 patients in 2000: 56 with spRA, 38 with snRA and 26 with SpA. All of them were treated in the Department of Rheumatology, which serves the population of northwestern Israel. Solar activity was analyzed according to the "Solar Terrestrial Activity Report Charts 1998-2000". The Central Israel Bureau of Statistics provided the sun global radiation data. Data was assessed during the summer (April-September) and winter (January-March, October-December). The correlation between the monthly distribution of disease relapses and solar factors was measured (SPSS-10 for WIN). RESULTS: Relapses in spRA patients occurred mostly during the summer months with peak activity during the month of July 2000. Single monthly peaks of spRA relapse onset were noted in January 1998-1999 and April 1998 and for snRA in January 1998 and June 2000, but there were no seasonal differences for spRA, snRA and SpA in 1998-1999 and for snRA and SpA in 2000. Relapses in spRA patients were associated with a summer bias of increased solar activity and global solar radiation in 2000 compared with lower peak solar activity in 1998-1999. Furthermore, in 2000 we found a significant correlation of the spRA monthly relapse count to solar activity (p = 0.005) and global sun radiation (p = 0.048) unlike snRA and SpA. No above-mentioned association and correlation was noted in 1998-1999. We revealed mild negative correlation (p = 0.046) of SpA relapse count only to peak solar flux (PSF) by analysis of data for 1998-2000 as one united group. CONCLUSIONS: Relapses were more frequent during the summer of 2000 (May-June-July) in spRA but not in snRA and SpA. The reasons are still unclear. No seasonal differences were observed in 1998-1999. Enhanced solar activity in summer-2000 compared with 1998-1999 may be inferred to be the proposed cause but coincidence may occur as well. Outbreak in RA and SpA was not registered despite increased peak solar activity in 2000. We observed mild evidence of reciprocal relation between SpA relapsing and solar activity during 1998-2000. Solar and any other possible contributory factors remain still to be elucidated.
