Tidskriftsartikel (refereegranskat)abstract
- Work from our laboratories has shown that the major antigenic determinants for rheumatoid factors (RFs) are in the C gamma 2-C gamma 3 interface region of IgG in the same area that binds staphylococcal protein A (SPA). Furthermore, the Fc binding proteins of groups A, C and G streptococci as well as the Fc binding proteins induced on cell surfaces by herpes simplex virus type I also bind to the same area of IgG. These binding site similarities between RFs and the microbial Fc binding proteins suggested conformational similarities between the RF antigen combining regions and the Fc binding regions of the microbial proteins. This hypothesis was supported by the observation that antibodies to SPA bind to the antigen combining regions of most RFs as well as to the Fc binding region of the T15 group A streptococcal Fc binding protein. These findings indicate that RFs bear the conformational internal image of these microbial proteins and suggest that RFs could arise as antibodies to the idiotypic determinants on antibodies to microbial Fc binding proteins. Alternatively, microbial Fc binding proteins could present IgG to the immune system in a way that renders specific areas of the C gamma 2-C gamma 3 interface region immunogenic. These relationships between RFs and microbial Fc binding proteins may prove to be important for our understanding of the generation of RFs in rheumatoid arthritis.

Acetylator phenotypes in rheumatoid-arthritis patients with or without adverse drug-reactions to sodium-aurothiomalate or d-penicillamine
- 1987
-

Tidskriftsartikel (refereegranskat)abstract
- The acetylator phenotype was determined in 59 patients with classical, seropositive and erosive rheumatoid arthritis (RA) treated with sodium-aurothiomalate or d-penicillamine. Patients with adverse drug reactions (ADR) leading to drug withdrawal (n=29) were compared with a group of patients without ADR (n=30). The frequency of slow acetylators was significantly (p< 0.05) increased in all RA patients, irrespective of the presence of ADR, particularly in the male patients, compared with a control population. No association was found between acetylator phenotype and clinical data or secondary Sjögrens's syndrome (SS).

Clinical symptoms and HLA antigens in a family with reiters disease
- 1985

Ingår i: Scandinavian Journal of Rheumatology. - 0300-9742 .- 1502-7732. ; 14:2, s. 149-158

Tidskriftsartikel (refereegranskat)abstract
- A clinical and immunogenetic study was performed on a three-generation family with Reiter's disease (RD). Twelve of 56 members of the family (33 clinically examined) including one in-law, had symptoms of arthritis, urethritis, conjunctivitis, uveitis, and/or mucocutaneous manifestations, but only one had the complete triad of Reiter's syndrome (RS). Radiographic sacro-iliitis was found in 7 individuals, and monoarticular onset was reported in 5 out of 7 with peripheral arthritis. HLA B27 was found in 26 of the 37 family members who were tissue typed (including one in-law). All individuals with RD were B27-positive. Seven different B27 phenotypes were identified. This finding suggests that RD is associated with the B27 antigen itself, and not to a gene closely linked to B27. From a pedigree analysis of this family an autosomal dominant inheritance with incomplete penetrance or multifactorial inheritance seemed the most probable alternatives. The family history is a useful adjunct in the diagnosis of RD.

HLA antigens in rheumatoid-arthritis patients with and without a family history of polyarthritis
- 1985
-
Ingår i: Scandinavian Journal of Rheumatology. - 0300-9742 .- 1502-7732. ; 14:4, s. 375-380

Tidskriftsartikel (refereegranskat)abstract
- The HLA antigens, A, B and DR, were studied in 141 patients with erosive, seropositive rheumatoid arthritis (RA). The frequency of the B27 antigen was significantly increased among patients with a family history of symmetrical polyarthritis compared with blood donor controls (p<0.001) and with patients without a family history of polyarthritis (p<0.005). The frequency of DR4 was significantly (p<0.001) increased among the RA patients, but there was no significant association between DR4 and a family history of polyarthritis.

Surface replacement of the hip in juvenile chronic arthritis

Tidskriftsartikel (refereegranskat)abstract
- Seventeen resurfacing arthroplasties undertaken in 13 patients with severe hip arthritis are described. The youngest patient was 14 years and the mean age 23 years. The average follow-up time is 2 years. In one patient, pain-free for 7 months, the femoral cup slipped and revision into total hip replacement was easily performed. The remaining patients are pain-free, have increased motion, a better walking capacity and can enjoy sex life. The tremendous improvement in quality of life for these young patients justifies operation even if all may have to be converted into total hip replacement within a couple of years, although there is nothing to indicate that in this early follow-up.

Backward tilting of the posterior atlantal arch in rheumatoid arthritis

Tidskriftsartikel (refereegranskat)abstract
- In a retrospective survey of 450 patients with rheumatoid arthritis on whom cervical spine radiography was performed, one patient was found with a backward tilting of the posterior arch of the atlas. With preserved relations anteriorly, the posterior arch was rotated downward in front of the spinous process of the axis, encroaching on the space of the spinal canal.

Posterior atlanto-axial dislocation in rheumatoid arthritis

Tidskriftsartikel (refereegranskat)abstract
- Seven patients with rheumatoid arthritis and posterior atlanto-axial dislocation are presented. The patients were elderly women who had suffered with the disease a long time. In all cases earlier cervical radiographs were available, excluding any predisposing congenital anomaly. Fracture and arthritic destruction of the dens, of parts of the body of the axis, or of the anterior arch of the atlas proved to be predisposing factors of the lesion.
