2.Using effects of leflunomide (arava) in treating rheumatoid arthritis - a multicenter study in Viet Nam
Journal of Practical Medicine 2003;466(11):49-54
The effect of leflunomide on the variation of clinical and laboratory parameters on patients suffering from rheumatismal arthritis at active stage and the monitoring of side effects were studied in a 6 month opening non-comparing clinical investigation at 4 institutions in Vietnam. Oral leflunomide was administered 1 tablet (100mg) daily in the first 3 day, then 20mg daily in 6 months continuously. Results showed that clinical testing mean parameters reduced by 28-77% after 2 months and 57-83% after 6 months. In 21.4% of patients, at least 1 side effect manifested at light to moderate level

BACKGROUND: The American College of Rheumatology/European League against Rheumatism classification criteria for rheumatoid arthritis (ACR/EULAR criteria) include the rheumatoid factor (RF) test and the anti-citrullinated peptide/protein antibody (ACPA) test as serologic makers for rheumatoid arthritis. Antiperinuclear factor (APF) test, an originator of ACPA, is highly specific for rheumatoid arthritis and can be detected in RF or anti-cyclic citrullinated peptide (anti-CCP) negative rheumatoid arthritis, but it is not included in the serologic criterion of ACR/EULAR criteria. In this study, we investigated the way for applying the APF test to ACR/EULAR criteria. METHODS: We analyzed clinical symptoms and laboratory findings of 53 patients who were suspected having rheumatoid arthritis. All patients were negative for the RF and anti-CCP and positive for APF. We classified these patients into 4 groups according to the fluorescence intensity of APF test, and gave 1-4 points for APF positivity. The proportion of patients who scored 6 or greater in ACR/EULAR criteria in relation to APF scores was evaluated. RESULTS: Median scores of ACR/EULAR criteria showed a tendency to increase as the level of fluorescence intensity of APF rises, but ACR/EULAR scores of 4 groups were not different significantly from each other (P>0.05). The proportion of patients who scored 6 or greater in ACR/EULAR criteria were 39.6% and 77.4%, when scores of APF positivity were 2 and 3 points, respectively. CONCLUSIONS: We think it is reasonable to include APF test in the ACPA of ACR/EULAR criteria and give 3 points for APF positivity, regardless of its fluorescence intensity.

OBJECTIVETo assess the effect and safety of periodontal therapy in relieving the symptoms and clinical signs of rheumatoid arthritis (RA).
METHODSThe electronic search was conducted in Medline (OVID, 1950-2010 Sep), EMBASE (1984-2010 Sep), CENTRAL (2010, Issue 3), CBM (1978-2010 Sep) and the Chinese journals on stomatology were hand-searched. Clinical randomized controlled trials as well as clinical controlled trials were selected regarding the targeted issue. Two investigators evaluated the reporting quality and risk of bias of those included trials in accordance with CONSORT statement and Cochrane risk of bias assessment tools, and collected data of included studies in duplicate. Revman 5.0.23 was applied for Meta-analysis.
RESULTSFour trials met the inclusion criteria and a total of 150 patients were enrolled in the trials, one had low risk of bias and others had moderate risk of bias. Meta-analysis showed that pure periodontal therapy could not decrease disease activity score in 28 joints (DAS28) (P=0.06), and there was no statistically significant difference between periodontal therapy with anti-tumor necrosis factor-alpha (TNF-alpha) medication and pure anti-TNF-alpha medication (P=0.24). But the subgroup analysis showed that a significantly decreased DAS28 was achieved by periodontal therapy (P=0.03), and the interventions provided a remarkable effect on alleviating clinical signs and erythrocyte sedimentation rate of RA (P<0.05). Results of the symptoms relief differed from the studies. No adverse events were reported.
CONCLUSIONThe evidence available currently indicates that periodontal therapy may play a positive role in remitting the clinical signs and periodontal status of RA except the relief of the symptoms.

Rheumatoid nodulosis, a benign variant of rheumatoid arthritis (RA), is a rare condition characterized by multiple subcutaneous nodules and positive rheumatoid factor in the absence of systemic manifestations or joint disease. Asymptomatic nodules rarely require treatment, and are unlikely to recur after excision, except in cases in which RA develops. Here, we describe an unusual case of recurrent rheumatoid nodulosis in a 42-year-old female presenting with recurrent subcutaneous nodules on the plantar side of her left foot, which caused pain when walking. Nodules were initially excised to control symptoms; however, since the excision, the nodules have recurred twice in the absence of other RA symptoms.

OBJECTIVE: This study was designed to evaluate clinical features of 20 patients with rhupus syndrome and compare its characteristics with systemic lupus erythematosus(SLE) and rheumatoid artiritis(RA). METHODS: Patients considered to have rhupus who met the American College of Rheumatology(ACR) 1997 and 1987 revised criteria for SLE and RA, respectively and age, sex, and disease duration matched 64 patients with RA and 56 patients with SLE were selected for comparison. RESULTS: Twenty patients were all female and their mean age was 43.7+/-9.6 years(range 25~68). They had 5.5 ACR criteria for RA and 5 criteria for SLE. The mean age at onset of RA was 35.2+/-10.5 years(19~63) and that of SLE was 38.2+/-10.0 years(20~63), giving a mean interval between the diagnoses of the two diseases of 3.0+/-5.7 years (14~(-6)). There were 2 patients(10%) with rheumatoid nodule, and 18 patients(90%) with rheumatoid factor, and 16 patients(80%) with bone erosions on hand or wrist joints. The criterial for SLE included malar rash(20%), discoid rash(0%), photosensitivity(30%), oral ulcer(45%), arthritis(100%), serositis(35%), renal disorder(15%), neurologic disorder(0%), hematologic disorder(100%), immunologic disorder(90%), and positive antinuclear antibody(100%). Anti-dsDNA was more than 7.0U/ml in 15 patients(75%). The patients with rhupus syndrome showed lower amount of 24 hour urine protein, more severe radiologic involvement, younger age at onset of arthritis, higher titer of rheumatoid factor, lower frequency of low C3, and less complicated clinical course when compared with the patients with SLE(p<0.05). More frequent anemia, Rayanud's phenomenon, and more complicated clinical course in rhupus when compared with the patientw with RA(p<0.05), but the radiologic stage of hand and wrist was similar between rhupus and RA. CONCLUSION: Rupus syndrome showed somethisg different clinical characteristics and clinical course when compared with SLE and RA.

Journal of the Korean Radiological Society 2000;42(2):349-352
We report a case of rheumatoid nodule of the right knee in a 55-year-old woman which on the basis of MR images was misdiagnosed as soft tissue sarcoma. Rheumatoid nodules occur in up to 20% of adult patients with rheumatoid arthritis and most patients with rheumatoid nodules are rheumatoid factor positive. The nod-ules are most commonly located between the skin and an underlying bony prominence. In this case, the patient had a history of rheumatoid arthritis and a soft tissue mass was present in the lateral aspect of the right knee. T1-weighted images revealed a mass of similar signal intensity to that of muscle, and on T2 weighted im-ages, a central portion of high signal intensity was noted. Enhanced T1 weighted images demonstrated periph-eral rim enhancement. The mass extended to subcutaneous tissue, with penetration of lateral patellar retinacu-lum. Excisional biopsy was performed, and the pathologic diagnosis was rheumatoid nodule. Although its radi-ologic findings are non-specific, rheumatoid nodule should - in appropriate clinical settings - be included in the differential diagnosis of a predominently solid or centrally necrotic periarticular soft tissue.
