Rats with adjuvant-induced arthritis were observed to have increased alkaline phosphatase, acid phosphatase (two isozymes), and ATPase activity in the radial zone of articular cartilage, at the osteochondral junction, and in the bone marrow elements. A qualitative and quantitative reduction azure A, PAS colloidal iron, alcian blud critical electrolyte concentration staining (0.4 and 0.9 M (mg Cl2) was also observed in corresponding areas. These findings suggest the degradation of the articular cartilage matrix with possible simultaneous or resultant calcification.

Nineteen patients with Paget's disease of bone were studied 7 months to 5 years after therapy with mithramycin in a dose averaging 11.5 microgram/kg body weight daily for 10 days. Thirteen patients, including 3 with the longest followup intervals, remained free of pain. Objective measures of disease activity (serum alkaline phosphatase level and 99mtechnetium pyrophosphate bone scan) were less favorable. There was no evidence of long term toxicity.

Incubates of articular cartilage from young but not mature rabbits, as well as growth plate cartilage, elaborated PPi into basel Eagle's medium during a 4-hour period. Control rabbit synovial membrane and ear cartilage elaborated negligible amounts of PPi. The PPi was shown to be nondialyzable but could be dissociated from the alkaline phosphatase by ultracentrifugation. In 16 patients with osteoarthritis a substantial output of PPi by samples of articular cartilage from the knee was demonstrated. The present authors believe that either rapid cell division and matrix synthesis found in the base of ulcerating osteoarthritic cartilage or remodeling calcified sites comprise the origin of the PPi in such osteoarthritic cartilage. They further theorize that this PPi output accounts for a considerable fraction, if not all, of the elevated PPi levels found in synovial fluid of patients with osteoarthritis.

An enzyme-linked immunosorbent assay for the detection and quantitation of human immunoglobulin M (IgM), IgG, and IgA antibodies against Yersinia enterocolitica is described. Formalinized or heat-treated bacteria were adsorbed onto specially designed microcuvettes, and antibodies were allowed to attach to the antigen-coated cuvettes. Rabbit anti-human mu, anti-human gamma, and anti-human alpha antisera were allowed to react with human antibodies, and these class-specific anti-immunoglobulins were detected by alkaline phosphatase-labeled swine anti-rabbit IgG. A total of 423 sera were tested. The results obtained with the enzyme-linked immunosorbent assay were compared with the results of the conventional tube agglutination test. Persistence of different antibodies was studied in six patients. Antibodies of the IgM class persisted only for 1 to 3 months after onset of the disease; thus the occurence of IgM-class Yersinia antibodies in a single sample indicates a recently acquired infection. The persistence of the IgG- and IgA-class antibodies was variable and not parallel with each other. Remarkably, all three patients in which the disease was complicated with arthritis had IgA-class Yersinia antibodies at the end of the follow-up period of 9 to 14 months, and in those without arthritis the IgA-class antibodies disappeared within 3 months after onset of the disease.

This paper establishes a quantitative technique for measuring the percentage of enzyme-reactive cells found in adjuvant arthritic articular cartilage, synovial membrane and bone marrow. Using alkaline phosphatase histochemistry and a recently-developed method of handling hard tissues, the technique is validated, the inherent variabilities determined and the existence of intra-articular lesions established. The technique now allows for a precise in situ evaluation of adjuvant arthritic drug inhibition by measuring enzyme-reactive cell alterations within the joint tissue most affected by the arthritis.

A systematic prospective survey of 100 outpatients with rheumatoid arthritis revealed that 45 had biochemical evidence of liver disease. In most cases this was due to increases in total serum alkaline phosphatase (ALP) and/or gammaglutamyl transpeptidase (GGT). Examination of serum ALP isoenzyme profiles in 50 of the patients showed that the liver isoenzyme was the sole or major component in 44 patients, including many with normal total ALP levels. 18% had raised serum liver ALP together with raised GGT, suggestive of an underlying hepatobiliary lesion. No correlation could be detected between raised serum levels of liver enzymes and the age or sex of the patient, duration or severity of arthritis, and drug or alcohol history. However, there was a significant correlation between raised serum ALP and lacrimal or salivary gland dysfunction. It is suggested that immunological mechanisms may be involved in the development of hepatic abnormalities in rheumatoid arthritis.

Peripheral venous blood samples were drawn before and after induction of adjuvant arthritis in rabbits at intervals of 15 days. Using these samples, biochemical parameters were measured, including total protein, albumin, globulin, cholesterol, alkaline phosphatase, glutamic oxaloacetic transaminase and glutamic pyruvic transaminase. The various biochemical tests exhibited an abnormal pattern in adjuvant animals as compared to the normal rabbits. The significance of these findings has been discussed.

A study of liver abnormalities in 36 patients with mixed cryoglobulinemia in the absence of underlying infectious, connective tissue, or lymphoproliferative disorders revealed clinical or biochemical evidence of liver dysfunction in 84%. Hepatomegaly was detected in 77%, splenomegaly in 54%, and abnormalities in bilirubin, alkaline phosphatase, or serum glutamic oxalacetic transaminase in 77%. Only four of the patients had overt liver disease. Of 15 biopsies from 12 patients, there was normal tissue structure in two, minimal nonspecific changes in one, portal fibrosis in three, chronic persistent hepatitis in one, chronic active hepatitis in two, chronic active hepatitis with cirrhosis in four, and postnecrotic cirrhosis in two. These findings, together with the previously reported high incidence of serologic evidence of hepatitis B virus (HBV) infection, support the view that the syndrome of purpura, arthritis, and nephritis is often a consequence of immune-complex vasculitis secondary to HBV infection.

Technetium 99m-polyphosphate bone images are correlated with bone roentgenography, and serum calcium, phosphorus and alkaline phosphatase in 91 patients with suspected bone metastasis. Technetium polyphosphate bone images are the most sensitive and serum level of calcium and phosphorus are the least sensitive indicator of bone lesions. Bone roentgenography is not as sensitive as technetium polyphosphate images. Abnormal bone images with normal or abnormal bone roentenography associated with increased alkaline phosphatase in the absence of liver metastasis are highly suggestive of metastatic bone disease. Abnormal bone images adjoining the joints, associated with normal serum alkaline phosphatase and abnormal joint roentgenography suggest arthritis. It is recommended that technetium 99m-labelled phosphate bone images are considered to be the diagnostic procedure of choice to detect skeletal lesions. Polyphosphate bone images are highly sensitive, with the combination of elevated alkaline phosphatase they become relatively more specific for a metastatic bone disease.
