DISCUSSION Hepatitis B reactivation is a well known adverse event in patients with chronic HBV infection receiving cytotoxic or immunosuppressive treatment. 3 Inhibition of TNFα might lead to ...additional advantages for viral replication owing to escape from host antiviral mechanisms. The antiviral activity of TNFα has long been recognised. 4 Indeed, synergistic activity of interferon GAMMA (INFGAMMA) and TNFα has been shown to affect early steps in herpes simplex virus replication at the level of early gene transcription and translation, 5 while these cytokines inhibit murine cytomegalovirus late gene transcription and DNA replication. 6 Data from animal models indicate that INFGAMMA and TNFα may also synergistically inhibit HBV gene expression and replication, leading to a reduction in the intracellular level of HBV transcripts. 7, 8 Moreover, TNFα, which is induced by HBV antigens, is supposed to be beneficial for viral clearance. 9 On the other hand, methotrexate might reduce the clearance of intrahepatic HBV depleting specific cytotoxic cells. 10 Despite the wide use of methotrexate in the treatment of RA and the high prevalence of HBV infections in some countries, to our knowledge, only two other cases 11, 12 with fulminant hepatitis B (precore variant mutant type) after two years' treatment and concomitant discontinuation of methotrexate have been reported.
Objective: To evaluate the efficacy and safety of monotherapy with adalimumab in patients with RA for whom previous DMARD treatment has failed. Methods: In a 26 week, double blind, placebo ...controlled, phase III trial, 544 patients with RA were randomised to monotherapy with adalimumab 20 mg every other week, 20 mg weekly, 40 mg every other week, 40 mg weekly, or placebo. The primary efficacy end point was ≥20% improvement in the ACR core criteria (ACR20 response). Secondary efficacy end points included ACR50, ACR70, EULAR responses, and the Disability Index of the Health Assessment Questionnaire (HAQ DI). Results: After 26 weeks, patients treated with adalimumab 20 mg every other week, 20 mg weekly, 40 mg every other week, and 40 mg weekly had significantly better response rates than those treated with placebo: ACR20 (35.8%, 39.3%, 46.0%, 53.4%, respectively v 19.1%; p⩽0.01); ACR50 (18.9%, 20.5%, 22.1%, 35.0% v 8.2%; p⩽0.05); ACR70 (8.5%, 9.8%, 12.4%, 18.4% v 1.8%; p⩽0.05). Moderate EULAR response rates were significantly greater with adalimumab than with placebo (41.5%, 48.2%, 55.8%, 63.1% v 26.4%; p⩽0.05). Patients treated with adalimumab achieved better improvements in mean HAQ DI than those receiving placebo (−0.29, −0.39, −0.38, −0.49 v −0.07; p⩽0.01). No significant differences were found between adalimumab and placebo treated patients for serious adverse events, serious infections, or malignancies. Injection site reaction occurred in 10.6% and 0.9% of adalimumab and placebo treated patients, respectively (p⩽0.05). Conclusion: Among patients with RA for whom previous DMARD treatment had failed, adalimumab monotherapy achieved significant, rapid, and sustained improvements in disease activity and improved physical function and was safe and well tolerated.
Objective: To evaluate traditional and non-traditional risk factors for subclinical atherosclerosis in systemic lupus erythematosus (SLE). Methods: A prospective cohort of 78 patients with SLE ...without overt atherosclerotic disease was studied. SLE clinical and laboratory parameters, disease activity and damage, treatment and traditional risk factors for atherosclerosis were evaluated. At baseline (T1) and after five years’ follow up (T2), the serum levels of anti-oxidised palmitoyl arachidonoyl phosphocholine (oxPAPC), anti-heat shock protein 65, and anti-β2-glycoprotein I antibodies and C reactive protein were tested. At T2, intima-media thickness (IMT) was measured using duplex carotid sonography. Thickened intima, plaque, mean IMT (m-IMT), and maximum IMT (M-IMT) were assessed. Results: A thickened intima was seen in 22/78 (28%) patients and plaque in 13/78 (17%). M-IMT and m-IMT were (mean (SD)) 0.77 (0.34) mm and 0.55 (0.15) mm, respectively. Patients with carotid abnormalities were significantly older, had higher blood pressure and total serum cholesterol levels, and had taken a higher prednisone cumulative dosage than those without any lesions. The carotid abnormalities were associated with renal disease and ECLAM >2 at T1, and with azathioprine treatment. In multivariate analysis, age and cumulative prednisone dose were associated with carotid abnormalities; age, hypertension, and anti-oxPAPC at T2 were correlated with higher M-IMT and m-IMT. Conclusions: In patients with SLE some non-traditional risk factors for atherosclerosis were identified, the most important of which was the cumulative prednisone dose. The role of some traditional risk factors, such as age and hypertension, was also confirmed. The predictive value of the new immunological and inflammatory markers of atherosclerosis seems to be masked by some disease related features.
Objective: To determine the effect of tumour necrosis factor α (TNFα) blockade with etanercept in refractory knee joint synovitis (KJS) in rheumatoid and psoriatic arthritis, by local and systemic ...disease activity assessment and combined grey scale and power Doppler ultrasonographic monitoring. Methods: 27 knees affected by rheumatoid KJS (n = 12) and psoriatic KJS (n = 8) were assessed before receiving treatment and at 3 and 12 months’ follow up. Time dependent clinical changes in disease activity were monitored by C reactive protein, erythrocyte sedimentation rate (ESR), global health status (GHS), and Ritchie (RAI) and knee joint articular (KJAI) indices; synovial changes were monitored by ultrasonographic and power Doppler indices for grey scale synovial thickening and for distinct intrasynovial vessel power Doppler flow configurations (fluid/synovium interface (F/SI-PD) and pannus/cartilage interface (P/CI-PD)). Interobserver and intraobserver variability of grey scale and power Doppler ultrasonographic was evaluated. Response to treatment was assessed by analysis of variance for repeated measures on clinical and ultrasonographic variables. Results: Rapid (3 months) reduction in F/SI-PD flow (p<0.001), parallel to reductions of C reactive protein (p<0.05), ESR (p<0.001), KJAI (p<0.002), RAI, and GHS (p<0.001), was sustained at 12 months when it was accompanied by reduction in both synovial thickening and P/CI-PD flow (p<0.001). No differences (ANOVA) were noted at baseline or at 12 months in clinical and ultrasonographic variables between either the rheumatoid or the psoriatic KJS groups. Conclusion: Grey scale and power Doppler ultrasonography are reliable measures of long term change in rheumatoid and psoriatic KJS disease activity in response to anti-TNFα treatment with etanercept.
Objective. To investigate the role of clinical, immunological and psychological variables in influencing the health-related quality of life (HRQOL) of Italian patients with systemic lupus ...erythematosus (SLE). Methods. The Medical Outcomes Study Short Form-36 was applied in a cohort of 126 SLE patients. At the time of HRQOL testing all patients underwent a clinical and laboratory evaluation, together with the measure of disease activity, severity and damage. In addition, a battery of psychological tests including the Hamilton Anxiety Scale (HAS) and the Hamilton Depression Rating scale (HAM-D) was applied. Results. The parameters which seemed to greatly influence the impairment of HRQOL were older age, arthralgia–arthritis and higher HAS scores as well as HAM-D. In multivariate analysis (adjusted for age), arthralgia–arthritis and a higher HAM-D score were associated with HRQOL impairment. No relationship between HRQOL and SLE activity, severity or damage were found. However, a relationship between HAS or HAM-D scores and damage or arthralgia–arthritis was noted. Conclusion. Anxiety, depression and joint pain seem to be the major determinants of HRQOL impairment in SLE patients. Damage seems to influence HRQOL mostly through depression.
Objective: To investigate the value of serum C reactive protein (CRP) as a marker of erosive osteoarthritis (EOA) of the hand. Methods: Ninety eight patients, 67 with EOA and 31 with non-EOA of the ...hand, were included in the study and analysed for radiographic score (RS), number of erosions, and joint count (JC) at clinical observation and at bone scintigraphy. CRP was assayed in a serum sample by a highly sensitive immunonephelometric method. Results: The median (interquartile range) CRP level was 4.7 (2.4–6.9) mg/l in the EOA and 2.1 (0.5–4.9) mg/l in the non-EOA group (p = 0.001). In all patients, CRP correlated with RS (rs = 0.43, p<0.001), and mainly with JC at clinical observation (rs = 0.72, p<0.001) and at bone scintigraphy (rs = 0.47, p<0.001). The correlation of CRP with RS and JC was confirmed at clinical observation and at bone scintigraphy in the EOA subgroup, but only with JC at clinical observation in the non-EOA subgroup. Conclusions: CRP levels are higher in EOA than in non-EOA patients. These levels probably reflect the disease activity of EOA, as suggested by correlations between CRP and JC at clinical observation and at bone scintigraphy.
Objective: To evaluate the clinical usefulness of serum autoantibody profiling in patients with autoimmune myositis.
Methods: We retrospectively studied 74 consecutive patients: 68 had definite or ...probable myositis according to Bohan-Peter criteria, six suffered from antisynthetase syndrome with subclinical myopathy. Myositis specific antibodies (MSA) (anti-ARS, -SRP, -Mi-2) were determined by RNA immunoprecipitation or immunoblot, myositis associated antibodies (MAA) (anti-RoRNP, -U1RNP, -PM/Scl, -Ku) by immunoblot.
Results: Forty-three patients (58%) were positive for MSA: anti-Jo-1 in 15/27 polymyositis (PM) (55%), 4/33 dermatomyositis (DM) (12%), 1/8 overlap (12%) and 2/6 antisynthetase syndrome (33%); anti-ARS non-Jo-1 in 1/27 PM (4%), 2/33 DM (6%) and 4/6 antisynthetase syndrome (67%); anti-Mi-2 in 1/27 PM (4%) and 11/33 DM (33%); anti-SRP in 3/27 PM (11%) and 1/33 DM (3%). One patient was anti-Jo-1/Mi-2 positive, one anti-Jo-1/SRP positive. Moreover, 27 patients (36%) were positive for MAA: anti-Ro/SSA in 8/27 PM (30%), 7/33 DM (21%), 1/8 overlap (12%), and 3/6 antisynthetase syndrome (50%); anti-U1RNP in 1/27 PM (3.7%), 1/33 DM (3%), and 2/8 overlap (25%); anti-PM/Scl in 2/8 overlap (25%), anti-Ku in 2/8 overlap (25%). Anti-Jo-1 was predominantly associated with PM, anti-Mi-2 was almost exclusively found in DM patients. Anti-ARS antibodies were closely associated with interstitial lung disease and polyarthritis; notably, anti-ARS non-Jo-1 was more frequent in patients without overt muscle alterations. Anti-Ro/SSA antibody was not associated with any disease subset, but significantly more frequent in antisynthetase syndrome.
Conclusions: Searching for MSA and MAA in patients with autoimmmune myositis is recommended because of its diagnostic and clinical value. Anti-ARS non-Jo-1 antibodies seem to preferentially target patients with pulmonary fibrosis without overt myopathy.
Arthritis and tenosynovitis are frequently reported as complications of inflammatory bowel diseases. About 10% of patients with ulcerative colitis presents articular inflammation, usually in the ...phases of activity of intestinal disease. Tenosynovitis is also a frequent complication of ulcerative colitis. We describe here a case of tenosynovitis of both ankles occurring in a patient affected by ulcerative colitis not in active phase. Chest X-ray and TC showed hilar lymph node enlargement and transbronchial biopsy confirmed the diagnosis of sarcoidosis. In this disease tenosynovitis is very rare, unlike arthritis that is rather common. In conclusion we observed a case of ankle bilateral tenosynovitis as onset manifestation of sarcoidosis.
