Studies of the action of some anti-inflammatory drugs on complement mediated immune haemolysis.

1 The effects of various anti-inflammatory and non-anti-inflammatory drugs on complement mediated haemolysis have been studied. Drugs which were significantly protein bound were found to inhibit this form of immune lysis, but only at greater concentrations than achieved therapeutically. 2 Removal of the drugs by prolonged dialysis resulted in restoration of complement activity with the exceptions of phenylbutazone and warfarin sodium. 3 Reconstitution experiments indicated that C2 and some of the later components especially C7 were affected by the drugs. 4 Intra-articular injections of prednisolone (100 mg) in patients with rheumatoid arthritis, failed to produce significant changes in the synovial fluid complement system. 5 None of the drugs affected the binding of antibody to antigen, or the ability of sensitized sheep cells to fix complement.

Autoantibodies in childhood connective tissue diseases and in normal children.

The prevalence of nine serum autoantibodies has been studied in 117 children with various connective tissue disorders and in 134 normal controls. In juvenile rheumatoid arthritis rheumatoid factor was present in 5%, and antinuclear factor in 4%, compared with an incidence of 4% and 0% respectively in controls. In Henoch-Schönlein purpura there was little evidence of associated autoimmune disorder. Gastric parietal cell and thyroid microsomal antibodies were found in 9% and 10% of our control population, but the significance of this is not clear. It is concluded that in children the presence or absence of autoantibodies as diagnostic criteria should be interpreted with the greatest caution.

Liver disease in rheumatoid arthritis and Sjøgren's syndrome. Prospective study using biochemical and serological markers of hepatic dysfunction.

Inter-relationships of biochemical and immunological tests of liver function have been studied in a prospective study of 216 patients with rheumatoid arthritis (RA), 32 patients with Sjogren's syndrome, and 27 patients with the sicca syndrome, and these results have been compared with those obtained 289 patients with osteoarthrosis or with a form of seronegative polyarthropathy. In general the prevalence of abnormalities in serum alkaline phosphatase, bromsulphthalein excretion, smooth muscle antibody, and mitochondrial antibody in the former three groups was higher than in patients with osteoarthrosis. Patients with Sjogren's syndrome with RA had a higher prevalence of abnormalities of bromsulphthalein excretion, salivary duct antibody than patients with the sicca syndrome. Patients with RA had a higher pervalence of rheumatoid factor than those with the sicca syndrome. Patients with a positive smooth muscle or mitochondrial antibody were found to have a higher prevalence of hepatomegaly and splenomegaly, of abnormal liver function tests, of other autoantibodies, and of histological abnromalitis of liver than those in whom these tests were negative.

Studies of the viral flora in keratoconjunctivitis sicca.

Fifty patients suffering from KCS and exhibiting various patterns of corneal staining with fluorescein were examined for adenovirus types 3, 7, 8, and 14, herpes simplex, and the TRIC group by tissue culture and immunofluorescein techniques. No viruses were detected by either methods, and it is considered that presumption of virus involvement in these cases is untenable.
