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)

DNA typing for HLA-DPB1*02 and -DPB1*04 in multiple sclerosis and juvenile rheumatoid arthritis.

DP gene typing using in vitro DNA amplification combined with sequence-specific oligonucleotide probes (SSOP) has recently been reported. The amplification step may be specific for the HLA-DPB locus, or it may be specific for one or a group of HLA-DPB alleles, thus increasing the discriminatory power of the system. We report the combined use of group-specific DNA in vitro amplification followed by SSOP in typing for DPB1*02 and DPB1*04 variants. The method was used to type for these variants in 96 randomly selected, healthy Danes, in 37 patients with pauciarticular juvenile rheumatoid arthritis (PJRA), and in 38 patients with multiple sclerosis (MS). Increased frequencies of the cellularly defined HLA-DPw2 in PJRA and of HLA-DPw4 in MS have previously been reported. In the patient groups, the frequencies of the DPB1*02 and DPB1*04 variants did not differ significantly from those expected based on the cellularly defined HLA-DP types of the patients and the frequencies of the DPB1*02 and DPB1*04 variants among healthy Danes.

The variable intrafamiliar expressivity in Pendred's syndrome.

This study presents clinical, audiological, radiological and biochemical data on 14 individuals representing 6 families, each including at least one patient with the classical Pendred's syndrome. The size of the thyroid, degree of hearing loss and result of the iodine perchlorate discharge test showed great variations, even between affected relatives. Based on these observations a new definition of Pendred's syndrome is proposed. The use of the iodine perchlorate discharge test for detection of healthy carriers among family members is suggested.

NcoI restriction fragment length polymorphism (RFLP) of the tumor necrosis factor (TNF alpha) region in four autoimmune diseases.

The two-allele NcoI Restriction Fragment Length Polymorphism (RFLP) of the TNF alpha region yielding bands of 5.5 and 10.5 kb was investigated in patients with systemic lupus erythematosus (SLE), pauciarticular juvenile rheumatoid arthritis (P-JRA), rheumatoid arthritis (RA) and primary Sjögren's syndrome (pSS). In all four disease, we found a decreased frequency of the 10.5 kb allele which, however, was significant only in the SLE group. In all conditions except RA, the frequency of the 5.5 kb fragment was increased. In pSS and SLE, the frequency of HLA-B8 was increased in 5.5 kb fragment positive patients compared with corresponding controls and thus, the increase of this band and the decrease of the 10.5 kb band may be secondary to HLA-B8 associations owing to strong positive linkage disequilibrium between HLA-B8 and the 5.5 kb band.

IL-6 gene polymorphism in rheumatoid arthritis, pauciarticular juvenile rheumatoid arthritis, systemic lupus erythematosus, and in healthy Danes.

The restriction enzymes MspI and BglII identify two different two-allele restriction fragment length polymorphisms (RFLP) in the human IL-6 genes of healthy Danes. Co-dominant segregation was demonstrated for both marker-systems and the test for Hardy-Weinberg equilibrium showed no significant deviation from expectations. There is a strong correlation between the two marker systems. The two IL-6 RFLP's were studied in Danish patients with rheumatoid arthritis, pauciarticular juvenile rheumatoid arthritis, and systemic lupus erythematosus. The frequencies of the MspI and BglII marker phenotypes did not differ between healthy controls and the three disease groups. No extra or missing DNA fragments were observed in the disease groups when compared with controls.

Thyroid function in patients with Pendred's syndrome.

Thyroid function was studied in 17 unrelated patients with Pendred's syndrome. Fourteen patients had been treated with L-thyroxine, which was withdrawn during the investigation. Eight of the patients had previously had a thyroid resection. Thirteen patients had goiter at the time of study. The serum total thyroxine and serum total triiodothyronine concentrations were normal in 8, of whom 3 had elevated serum TSH concentrations. In the remaining 9 cases the thyroxine levels were below normal with elevated TSH. Serum reverse triiodothyronine concentrations were decreased in 8 out of 11. Median serum thyroglobulin was 973 micrograms/l (range 10.9-3200 micrograms/l) and increased in 13. Three patients had slightly positive thyroglobulin antibodies and one with normal level was thyrodectomized. Thyroid stimulating antibodies as measured by adenylate cyclase stimulation (median 114%, range 85-137%) were slightly increased in 11. When measured as TSH binding inhibiting immunoglobulins none were positive. Thyroid microsomal antibodies were negative in all. All patients with a detectable 131I uptake (n = 15) showed a pathological iodide perchlorate discharge test (median 32%, range 16-46%). These findings indicate an organification defect with impaired hormone synthesis.

The perchlorate discharge test with and without supplement of potassium iodide.

The purpose of the study was to compare the discharge of radioactive iodine from the thyroid after po administration of perchlorate with and without supplement of 2 mg potassium iodine (Kl) in 42 euthyroid controls, 26 patients with nontoxic goiter, 39 patients with thyrotoxicosis treated with radioactive iodine, and 39 patients with Pendred's syndrome. The discharge test was found to have a satisfactory specificity with supplement of 2 mg Kl, and was more sensitive to detect an organification defect than the standard perchlorate discharge test without Kl. In all groups of patients a significant discharge occurred after addition of Kl in contrast to healthy persons. Only in the group of patients with Pendred's syndrome a discharge of iodine was found in the perchlorate test without Kl.

Increased prevalence of late stage T cell activation antigen (VLA-1) in active juvenile chronic arthritis.

The presence of activated T cells as judged from the reaction with monoclonal antibodies (MoAb) against (a) a late stage T cell activation antigen (VLA-1), (b) the interleukin 2 (IL2) receptor (CD25), and (c) four different HLA class II molecules (HLA-DR, DRw52, DQ, and DP) was studied in 15 patients with active juvenile chronic arthritis (JCA), 10 patients with JCA in remission, and 11 age matched, healthy controls. In addition, the distribution of T 'helper/inducer' (CD4+), T 'suppressor/inducer' (CD4+, Leu8+), T 'suppressor/cytotoxic' (CD8+), and 'natural killer' (NK) cells (CD16+) was studied. Twenty patients and six controls were investigated for the capability to stimulate alloreactivated primed lymphocytes. The prevalence of VLA-1 positive, large cells was significantly increased to 5% (median value) in active JCA as compared with JCA in remission (2%, p less than 0.05) and controls (1%, p less than 0.05), whereas no significant difference between JCA in remission and controls was observed. Except for two patients with active JCA, less than 1% IL2 receptor bearing cells were found in patients with JCA and controls. No significant difference in the prevalence and expression of the various HLA class II antigens was observed between the groups. Similarly, no significant differences in stimulatory capability in secondary mixed lymphocyte culture (MLC) were seen. The distribution of T helper/inducer (CD4+), T suppressor/cytotoxic (CD8+), and NK cells was similar in active JCA, JCA in remission, and controls. The prevalence of T suppressor/inducer (CD4+,Leu8+) cells was higher in remission JCA (17%) than in active JCA (11%) and controls (10%). This increase, however, did not reach statistical significance. In conclusion, late stage but not early stage T cell activation antigens were increased in patients with active JCA as compared with patients with JCA in remission and control, whereas some patients in remission had an increased prevalence of T suppressor/inducer cells.

Volvulus of the cecum.

Twenty-six cases are reported of ileo-cecal volvulus admitted to three community hospitals over a period of six years. The operative management of ileo-cecal volvulus is discussed. Based on the results and review of the literature the authors recommend a right hemicolectomy in the presence of gangrene or perforation, in other cases a cecopexia with fixation in combination with intestinal tube decompression when needed.

Indomethacin treatment of acute pancreatitis. A controlled double-blind trial.

Thirty patients with acute pancreatitis were allocated to indomethacin suppositories, 50 mg twice daily, or identical-looking placebo suppositories for 7 days in a controlled double-blind trial. The groups of patients were not different with regard to age, sex, etiology, or number of Ranson criteria. The number of days with pain and number of opiate injections were significantly less in patients treated with indomethacin. The median values of serum amylase and serum calcium were not different before or at any day during treatment. Bleeding from the gastrointestinal tract was not seen.
