1.  Detection of cytomegalovirus antigens in phagocytosed serum complexes from a patient with rheumatoid arthritis, vasculitis, peripheral neuropathy, cutaneous ulceration, and digital gangrene. 
Annals of the Rheumatic Diseases  1992;51(4):553-555.
A patient with rheumatoid arthritis, vasculitis, peripheral neuropathy, cutaneous ulceration, and digital gangrene was studied. Circulating immune complexes were detected by C1q binding although serum complement levels were within the normal range. Immunofluorescent staining of buffy coat cells with specific antisera showed the presence of IgG and IgM in phagocytosed inclusions but complement C3 was not detected. A monoclonal antibody specific for cytomegalovirus detected antigens in phagocytosed inclusions on one occasion. These results may suggest that cytomegalovirus antigens are a hitherto unidentified component of serum complexes in patients with rheumatoid arthritis and may contribute to the pathogenesis of the vasculitic complications of rheumatoid arthritis by participating in immune complex formation.

3.  Immunological studies of the placenta in systemic lupus erythematosus. 
Annals of the Rheumatic Diseases  1978;37(2):129-134.
An immunological study was made of the placentae from 5 mothers with lupus erythematosus. 3 of the 5 mothers had anti-DNA antibodies in their sera at the time of delivery and in one of these anti-DNA antibodies were detected in the cord blood. This patient had active renal disease and serological evidence suggestive of circulating immune complexes in her blood at the time of delivery. Immunofluorescence studies showed granular deposition of immunoglobulin and C3 on the trophoblast basement membrane similar to that previously described on the glomerular basement membrane in systemic lupus erythematosus. Anti-DNA antibodies were eluted from the placenta in this case. We suggest that immune complex deposition on the trophoblast basement membrane in patients with active systemic lupus erythematosus may play a part in the increased fetal mortality in this disease.

5.  Rheumatoid Arthritis, Rheumatoid Factor, and Tests for Australia or Hepatitis-associated Antigen 
British Medical Journal  1972;4(5831):23-24.
False-positive results in tests for hepatitis-associated antigen using latex agglutination techniques may be due to rheumatoid factor in the serum. Possibly the use of IgM antibody in preparing the latex particles might diminish the occurrence of such reactions. No evidence was found for a relation between rheumatoid arthritis and a significant incidence of hepatitis-associated antigen detectable by countercurrent immunoelectro-osmophoresis.

6.  Aetiology of rheumatoid arthritis: an attempt to transmit an infective agent from patients with rheumatoid arthritis to baboons. 
Annals of the Rheumatic Diseases  1983;42(4):443-447.
Thirty baboons were injected intravenously and intra-articularly with material from the joints of 19 patients with active rheumatoid arthritis or with control material. Fifteen of the 30 animals received synovial fluid cells or synovial membrane cells from 3 patients with seronegative arthritis. Ten animals received pooled cells from a total of 16 cases of seropositive arthritis. Five animals were given nonrheumatoid cells. No signs of arthritis were recognised in the 27 surviving animals during 3 years of observation. No significant biochemical, haematological, or serological changes occurred during this period, and no gross or microscopic evidence of synovial or systemic disease was found post mortem.

7.  Viruses and lymphocytes in rheumatoid arthritis. II. Examination of lymphocytes and sera from patients with rheumatoid arthritis for evidence of retrovirus infection. 
Annals of the Rheumatic Diseases  1979;38(6):514-525.
The possible involvement of retroviruses in the aetiology of rheumatoid arthritis (RA) was investigated. Retrovirus antigens were not expressed on rheumatoid synovial and peripheral blood lymphocytes as judged by membrane immunofluorescence, radioimmunoassay, and complement-mediated cytotoxicity. The specific antiretroviral (anti-RD-144 and anti-SSAV) sera used in this study were produced in rabbits immunised with viral antigens grown in a homologous system (rabbit cells and medium supplemented with normal rabbit serum), avoiding non-specific immunofluorescence previously detected with donated antiretroviral sera. Immune complexes lodged in the rheumatoid synovial membranes did not contain, and other cells within the membranes did not express, retroviral antigens. Antibodies cross-reacting with primate retrovirus antigens were sought in sera from patients with 'autoimmune' diseases by means of solid phase radioimmunoassay. There were no retrovirus antibodies in the 3 groups of patients studied, that is, those with rheumatoid arthritis, systemic lupus erythematosus, and with non-RA conditions. Absorption of rheumatoid factor did not alter this conclusion. These results give little support to the hypothesis that activation of endogenous human retroviruses or an infection with horizontally transmitted retroviruses is associated with the rheumatoid process.

8.  Rheumatoid polyarthritis after rubella. 
Annals of the Rheumatic Diseases  1978;37(3):266-272.
A 21-year-old woman developed persistent polyarthritis indistinguishable from rheumatoid arthritis after rubella. The arthritis persisted for approximately 30 months and was associated with high levels of antibody to rubella virus and with rheumatoid factor. The antibody titres declined pari passu with clinical improvement which progressed to complete resolution. Fractionation of serial serum specimens showed a substantial and persistent IgM antibody response to rubella virus. Rubella antigen was not demonstrated in the synovial exudate.

An immunohistological survey of 28 full-term human placentas has demonstrated deposits of IgG, β1C, β1E, and fibrinogen/fibrin in areas of fibrinoid necrosis and on the trophoblast basement membrane in approximately 35% of placental villi. Traces of IgM were detected at similar sites in 18 of 28 full-term placentas. In 11 specimens of immature placentas (10–18 wk gestation) traces of IgG and β1C and deposits of fibrinogen/fibrin were also present, but IgM was not detected in this material. IgG was recovered in acidic eluates from an homogenized placenta which behaved as an antibody reactive with unidentified material present in fibrinoid deposits and on the thickened trophoblast basement membrane of some villi. It could not be determined whether this IgG was derived from the maternal or fetal circulation.
