TL;DR: In this chapter, the current information available concerning autoantibodies to intracellular antigens in SLE is discussed.
Abstract: Systemic lupus erythematosus (SLE) is a disease which has engaged the clinical and research efforts of many groups of investigators, including rheumatologists, nephrologists, dermatologists, and hematologists. In addition, many immunologists interested in mechanisms underlying autoimmunity have studied patients with SLE and models of this disease in experimental animals. There is abundant evidence showing that immune complexes are involved in the generalized vasculitis and more specifically in the nephritis seen in patients with SLE. The immune complex disease is known to be related to circulating autoantibodies, and in this chapter we shall discuss the current information available concerning autoantibodies to intracellular antigens in SLE.

TL;DR: A method has been devised for the electrophoretic transfer of proteins from polyacrylamide gels to nitrocellulose sheets that results in quantitative transfer of ribosomal proteins from gels containing urea.
Abstract: A method has been devised for the electrophoretic transfer of proteins from polyacrylamide gels to nitrocellulose sheets. The method results in quantitative transfer of ribosomal proteins from gels containing urea. For sodium dodecyl sulfate gels, the original band pattern was obtained with no loss of resolution, but the transfer was not quantitative. The method allows detection of proteins by autoradiography and is simpler than conventional procedures. The immobilized proteins were detectable by immunological procedures. All additional binding capacity on the nitrocellulose was blocked with excess protein; then a specific antibody was bound and, finally, a second antibody directed against the first antibody. The second antibody was either radioactively labeled or conjugated to fluorescein or to peroxidase. The specific protein was then detected by either autoradiography, under UV light, or by the peroxidase reaction product, respectively. In the latter case, as little as 100 pg of protein was clearly detectable. It is anticipated that the procedure will be applicable to analysis of a wide variety of proteins with specific reactions or ligands.

TL;DR: In 1992, Piette and colleagues suggested that the ACR revised criteria be reevaluated in light of the above discoveries, and the presence and clinical associations or antiphospholipid antibodies in patients with SLE was suggested.
Abstract: In 1982, the Diagnostic and Therapeutic Criteria Committee of the American College of Rheumatology (ACR)published revised criteria for the classification of systemiclupus erythematosus (SLE) (1). During the ensuing decade several investigators, including Drs. Graham Hughes and Donato Alarcon-Segovia, among others, have described the presence and clinical associations or antiphospholipid antibodies in patients with SLE, as well as the occurrence of theprimary antiphospholipid syndrome (2-5). In 1992, Piette and colleagues suggested that the ACR revised criteria be reevaluated in light of the above discoveries (6).

TL;DR: Variables from the medical history, physical examination, laboratory tests, and radiographs were used to develop sets of criteria that serve different investigative purposes and these proposed criteria utilize classification trees, or algorithms.
Abstract: For the purposes of classification, it should be specified whether osteoarthritis (OA) of the knee is of unknown origin (idiopathic, primary) or is related to a known medical condition or event (secondary). Clinical criteria for the classification of idiopathic OA of the knee were developed through a multicenter study group. Comparison diagnoses included rheumatoid arthritis and other painful conditions of the knee, exclusive of referred or para-articular pain. Variables from the medical history, physical examination, laboratory tests, and radiographs were used to develop sets of criteria that serve different investigative purposes. In contrast to prior criteria, these proposed criteria utilize classification trees, or algorithms.

TL;DR: The study showed the clinical history screening test for AS to be moderately sensitive, but it might be better in clinical practice, and substitution of the Rome pain criterion for the New York pain criterion is proposed.
Abstract: The New York and the Rome diagnostic criteria for ankylosing spondylitis (AS) and the clinical history screening test for AS were evaluated in relatives of AS patients and in population control subjects. The New York criterion of pain in the (dorso) lumbar spine lacks specificity, and the chest expansion criterion is too insensitive. The Rome criterion of low back pain for more than 3 months is very useful. Our study showed the clinical history screening test for AS to be moderately sensitive, but it might be better in clinical practice. As a modification of the New York criteria, substitution of the Rome pain criterion for the New York pain criterion is proposed.
