Interferon-alpha combined with ketoprofen as treatment of naïve patients with chronic hepatitis C: a randomized controlled trial.

In this randomized controlled study, we evaluated the efficacy and safety of interferon-alpha combined with ketoprofen to that of interferon-alpha alone in naïve patients with chronic hepatitis C. Forty patients were randomized to receive Interferon-alpha2a (3 million units three times a week) and ketoprofen (150 mg twice a day) and 40 to receive only interferon-alpha2a at the same dose. Patients were treated for 6 months and followed up for 6 months. Response was defined by undetectable HCV-RNA in serum at the end-of-treatment and after 6 months from the completion of therapy (long term response). At the end of treatment the response was similar in the two group. However, combination treatment showed significantly higher efficacy than monotherapy in achieving long term response (10%vs 32.5%; P = 0.014). Overall adverse events were similar in the two groups. 'Flu-like syndrome was significantly less common in the ketoprofen plus interferon group which experienced a significantly higher incidence of epigastric pain'. Our results indicate that the combination of ketoprofen plus interferon is significantly more effective than interferon alone in the treatment of naïve patients with chronic hepatitis C and is well tolerated. However this combined treatment appears to be less effective than the association of pegylated IFN and ribavirin which represent the current standard treatment. Thus, the role of ketoprofen in the treatment of chronic hepatitis C needs to be further evaluated against such a treatment.

Meta-analysis of three double-blind comparative trials with sustained-release etodolac in the treatment of osteoarthritis of the knee.

A meta-analysis was done with the final data from three trials that provided the first results relating to efficacy and safety of the new sustained-release (SR) formulation of etodolac versus established nonsteroidal anti-inflammatory drugs (NSAIDs) in the treatment of osteoarthritis (OA) of the knee. The studies were 4-week, double-blind, randomized, parallel-group comparisons of etodolac SR 600 mg (119 patients) against diclofenac SR 100 mg (54 patients), tenoxicam 20 mg (46 patients), or piroxicam 20 mg (18 patients). The primary efficacy parameters (assessed after 2 and 4 weeks of treatment) were physicians' and patients' overall assessments of patients' condition, night pain, and pain intensity. All patients had radiographic and clinical evidence of OA of the knee. For the meta-analysis, the data from the individual etodolac SR studies were pooled and compared with the pooled data for diclofenac SR, tenoxicam, and piroxicam. The homogeneity of the treatments across studies and the changes from baseline between groups were tested using a Cochran-Mantel-Haenszel test and an analysis of variance, including "study," "treatment," and "center within treatment" effects and their interaction. The analysis for the efficacy parameters was based on the final assessment during therapy (last visit). At baseline, the two treatment groups were comparable. Improvement rates were high in both groups (range, 68-81%), indicating that treatments were effective for most patients. No significant treatment difference was observed for the patients' overall assessment, night pain, or pain intensity. Both etodolac SR and the reference preparations were well tolerated. No clinically significant changes were noted in the laboratory data.(ABSTRACT TRUNCATED AT 250 WORDS)

Meta-analysis of two double-blind comparative studies with the sustained-release form of etodolac in rheumatoid arthritis.

A meta-analysis was done with the data from two studies that provided the first efficacy and safety results for the new sustained-release (SR) formulation of etodolac versus established nonsteroidal anti-inflammatory drugs in patients with rheumatoid arthritis (RA). The studies were 4-week, double-blind, multicenter, randomized, parallel-group comparisons of etodolac SR 600 mg (102 patients) with either diclofenac SR 100 mg (65 patients) or piroxicam 20 mg (35 patients). The data for etodolac SR were pooled and compared with the pooled data for the comparators. The primary efficacy assessments (weeks 2 and 4) were physician and patient overall evaluation of the patient's condition, number of painful/tender joints, and number of swollen joints. Patients met at least five of the American Rheumatism Association diagnostic criteria and were within Steinbrocker progression stage I, II, or III and functional class I, II, or III. The homogeneity of the treatment groups across studies and the changes from baseline between groups were tested using a Cochran-Mantel-Haenszel test and an analysis of variance including "study," "treatment," and "center within treatment" factors and their interaction. The efficacy analysis was based on the final assessment during therapy (last visit). The patients in the etodolac SR group were older than those in the comparators group (P = 0.032), and there were more patients over 65 years of age in the etodolac SR group than in the comparators group (31% versus 14%, respectively; P = 0.004).(ABSTRACT TRUNCATED AT 250 WORDS)

Expression of CD69 antigen on synovial fluid T cells in patients with rheumatoid arthritis and other chronic synovitis.

OBJECTIVES: The expression of the CD69 antigen on synovial fluid and peripheral blood lymphocytes was studied in 12 patients with rheumatoid arthritis (RA), five subjects with other forms of chronic synovitis, and on the peripheral blood lymphocytes of 15 patients with systemic lupus erythematosus (SLE) and immune vasculitis. METHODS: The CD69 antigen and other activation markers (HLA-DR, interleukin 2 receptor (IL-2R), transferrin receptor) were measured by cytometric analysis. In patients with RA soluble IL-2R was determined by enzyme linked immunosorbent assay (ELISA). RESULTS: The percentage of T cells bearing CD69 was significantly increased in synovial fluid from patients with RA (30.3 (13)%) and other chronic synovitis (18 (9)%). The expression of CD69 on peripheral blood lymphocytes of patients with RA, other chronic synovitis, and SLE and immune vasculitis was within the normal range 2.1 (1.2)%. According to previously published work, a high proportion of synovial fluid T cells are HLA-DR positive (64.2 (12.4)% in synovial fluid from patients with RA and 61 (1.2)% in synovial fluid from patients with other chronic synovitis). Transferrin receptor expression on synovial fluid was up-regulated compared with that on peripheral blood. The increase of IL-2R expression on synovial fluid lymphocytes v peripheral blood was not significant; the quantitative determination of soluble IL-2R levels gave a mean value of 921 (351) U/ml in synovial fluid of patients with RA, 672 (229) U/ml in the serum of the same patients, and 273 (100) U/ml in serum from normal subjects. CONCLUSIONS: Synovial fluid lymphocytes are in a different functional state than peripheral blood lymphocytes. CD69 antigen is an interesting cellular marker which should be studied in patients with chronic synovitis. The unusual expression of the activation antigens and the sequence of their appearance require further study.

[Clinical experience with the use of piroxicam in fast-dissolving sublingual capsules in acute recurrent osteoarthritis].

Open, non comparative study to evaluate the efficacy and safety of piroxicam Fast Dissolving Dosage Form (FDDF) for sublingual administration in treatment of reacutized osteoarthritis. Fifty-four patients with flare-ups of osteoarthritis involving various joints were enrolled in the study. They were treated with 20 mg/die piroxicam sublingual tablets for a total of 4 weeks. Drug efficacy was evaluated on the basis of the variation of spontaneous pain, pain on passive motion, functional limitation and capacity of performing a specific activity. Intensity of spontaneous pain on the first day showed a statistically significant improvement (p < 0.0001) only 15 minutes after the drug administration. This improvement in pain intensity increased until day 3. All other efficacy parameters showed a statistically significant improvement (p < 0.0001) 7 days after the beginning of treatment. Local and systemic tolerability was good. No patient showed local side effects; only 6 patients experienced systemic side effects. In conclusion, piroxicam sublingual tablets for treatment of osteoarthritis flare-ups showed analgesic efficacy already 15 minutes after drug administration, and good anti-inflammatory efficacy with good local and systemic tolerability.

Prevalence and clinical associations of anticardiolipin antibodies in systemic lupus erythematosus: a prospective study.

The main objectives of the present study were to determine the prevalence of IgG and IgM anticardiolipin antibody (aCL) isotypes in systemic lupus erythematosus (SLE) in order to analyze their possible association with the clinical manifestations of the disease. Clinical features of 64 consecutive and unselected SLE patients were prospectively studied. Sera from the same patients taken during each clinical manifestation were tested for the presence of aCL. The prevalence of aCL was 43.75% for the IgG isotype and 9.4% for the IgM isotype. A strong linkage between the presence of these antibodies and the occurrence of both thrombosis and abortions was found: a weaker association with neurological events and thrombocytopenia was also demonstrated. The titre of aCL appeared to be linked with the probability of having the clinical manifestations associated with these autoantibodies. Our results suggest that thrombosis and abortion, and possibly thrombocytopenia and central nervous system involvement, may be associated with the presence of aCL at the time when these clinical events develop in SLE patients.
