Comparison of two ibuprofen formulations in the treatment of shoulder tendonitis.

In order to compare the efficacy and tolerance of two drug formulations of ibuprofen, conventional tablets 600 mg QID (CI) and sustained-release tablets 1200 mg BID (SRI), a total of 147 patients in 7 centres in Denmark with nontraumatic shoulder pain were included in a double-blind dummy study. Initially all patients received a local injection of corticosteroid and local anaesthetic, and were randomly allocated either drug (CI or SRI) for a period of 3 weeks. Complete relief was recorded from significantly more of the patients in the CI group (21%) than in the SRI group (7%) while a similar number of patients improved viz., 67% of the SRI treated group and 77% of the CI treated group. Based on doctor's assessment improvement in the two groups was equal. 44% of the patients recorded side effects, the number and pattern being the same in the two groups. No serious side effects were recorded. It is concluded that the two treatment regimens can be rated as clinically equivalent.

Restriction fragment length polymorphism of two HLA-B-associated transcripts genes in five autoimmune diseases.

The restriction fragment length polymorphism of the two human HLA-B-associated transcripts (BATs) genes, BAT1 and BAT2, identifying polymorphic bands of 12, 8, 2.5, and 1.1 kb, and at 3.3, 2.7, 2.3, and 0.9 kb, respectively, was investigated in patients with primary biliary cirrhosis (PBC), systemic lupus erythematosus (SLE), pauciarticular juvenile rheumatoid arthritis (P-JRA), rheumatoid arthritis (RA), and primary Sjögren's syndrome (pSS), and in healthy Danes. The BAT2/RsaI 2.7-kb band fragment was more frequent in PBC, pSS, and SLE than in controls, but the p values did not reach significance when corrected for multiple comparisons. For pSS and SLE, the associations may be secondary to primary associations with HLA-B8 because the BAT2/RsaI 2.3-kb band, which is allelic to the BAT2/RsaI 2.7-kb band, is strongly negatively associated with HLA-B8 and HLA-DR3. The only significance obtained shows that the HLA-B8 frequency is increased in BAT2/RsaI 2.7-kb positive pSS patients as compared to the corresponding controls indicating that the HLA-B8 association may be strongest. No missing or extra DNA fragments were observed in the disease groups when compared with controls indicating that gross deletions or duplications of the BAT1 and BAT2 genes in the patients are unlikely. In conclusions, it cannot be excluded that the BAT2/RsaI 2.7-kb band may contribute to the susceptibility to PBC, pSS, and SLE.

DNA polymorphism of HLA class II genes in pauciarticular juvenile rheumatoid arthritis.

We investigated the DNA restriction fragment length polymorphism (RFLP) of the major histocompatibility complex (MHC) class II genes: HLA-DRB, -DQA, -DQB, DPA, and -DPB in 54 patients with pauciarticular juvenile rheumatoid arthritis (PJRA) and in healthy Danes. The frequencies of DNA fragments associated with the following HLA class II genes were increased in PJRA when compared to normal controls: DRB1*08 (DRw8) (35.2% vs 10.3%, RR = 4.6, p less than 10(-3), DRB3*01/02/03 (DRw52) (76.3% vs 48.1%, RR 3.5, p less than 10(-3)), DQA1*0401 (41.0% vs 7.4%, RR = 7.9, p less than 10(-3)), DQA1*0501 (55.6% vs 29.7%, RR = 3.0, p less than 10(-2), DQB1*0301 (DQw7) (46.2% vs 17.5%, RR = 4.0; p less than 10(-2)), DPA1*0201 (44.2% vs 7.9%, RR = 8.7, p less than 10(-5)), and DPB1*02 (DPw2) (40.7% vs 7.1%, RR = 8.5, p less than 10(-6)). The frequency of DRB1*11 was not significantly increased. The frequencies of DNA fragments associated with the following HLA class II genes were decreased in PJRA although not statistically significantly so after 'correction' of p values: DRB1*04 (14.8% vs 40.2%, RR = 0.27; p less than 10(-3)), DRB1*07 (0% vs 25.9%, RR = 0.04, p less than 10(-3)), DRB4*0101 (DRw53) (25.9% vs 53.6%, RR = 0.31, p less than 10(-3)), DQA1*0102 (11.6% vs 36.0%, RR = 0.25, p less than 10(-4)), and DQA1*0201 (2.6% vs 34.2%, RR = 0.05, p less than 10(-2)).(ABSTRACT TRUNCATED AT 250 WORDS)

A comparative study of the protein pattern in serum and synovial fluid.

A routine program for evaluation of the protein pattern in serum and synovial fluid has been tested on 25 patients in a consecutive study. The program comprised agar gel electrophoresis, total protein and albumin determination, and immunochemical determination of antitrypsin, orosomucoid, haptoglobin, IgR, and IgA. Linear correlation analysis of corresponding data in serum and synovial fluid gave r-values for the five latter components which varied from 0.74 to 0.87. On this basis reference intervals in synovial fluid could be established. Total protein, haptoglobin and IgG were elevated in rheumatoid arthritis, compared with osteoarthritis.

Reiter's disease and the histocompatibility antigen, HL-A 27.

HL-A27 were found in 31 of 48 patients with Reiter's disease (65%) as compared with 8% of 2 103 health controls. It is suggested that HL-A27 is closely related to the inheritance of a special immune response leading to an increased susceptibility to a special type of reactive arthritis which Reiter's disease has in common with ankylosing spondylitis and a certain type of psoriatic arthritis.
