The clinical spectrum of Reiter's syndrome and similar postenteric arthropathies.

Certain infections of the genitourinary and gastrointestinal tracts, such as nongonococcal urethritis, dysentery and yersiniosis, precipitate characteristic arthritic syndromes in genetically susceptible individuals. Eye and skin lesions in the form of conjunctivitis, iritis, keratodermia blenorrhagica and erythema nodosum occurring in association with particular distributions of arthritis make recognizable clinical entities. Reiter's syndrome may be diagnosed with certainty from the presence of tender heels, low back pain, a predominance of knee and foot arthritis and pyuria, when the more obvious clinical markers of the syndrome are absent; a flagrant case represents one of the easiest clinical diagnoses in medicine. Diagnosis is important for a good prognosis, optimal treatment and sometimes prophylactic measures. Sacroiliitis often progressing to spinal ankylosis is a prominant feature in the B27-positive patient. Erythema nodosum occurs in B27-negative subjects as a response to yersiniosis and ulcerative colitis.

Synthesis by an established lymphocyte cell line from a rheumatoid synovium.

Lymphocytes derived from the synovium of a patient with rheumatoid arthritis were shown to synthesize predominantly IgG as measured by an equilibrium binding assay. Chromatographic separation of the radiolabeled lymphocyte culture supernatant revealed rheumatoid factor activity associated with IgG and IgM. In addition, immunofluorescence studies on fixed lymphocytes demonstrated that the majority of cells stained positive for both IgG and rheumatoid factor.

D-penicillamine in the treatment of rheumatoid arthritis.

Forty-four patients with definite or classic rheumatoid arthritis and failure to tolerate or respond to gold therapy were treated with D-penicillamine on a so-called go-slow, go-low regime. Seventeen patients tolerated the drug and had a 3-13 month follow-up assessment; 8 were markedly improved, 6 moderately or slightly improved, and 3 unimproved. Penicillamine had to be discontinued in 9 patients because of toxic side effects.

Inhibition of growth of T-strain mycoplasmas by hydroxamic acids and by aurothiomalate.

Sorbyl-, benzoyl-, and 3-amino-benzoyl hydroxamic acids inhibited the development of an alkaline pH by T-strain cultures grown in broth containing 0.05% urea and phenol red. The specificity of this urease inhibition was demonstrated by the inhibition, by 10(-4)m sorbyl-hydroxamic acid, of the release of (14)CO(2) from (14)C-urea by washed T-strain mycoplasmas in 4 hr of incubation. Sorbyl-, benzoyl-, and 3-amino-benzoyl hydroxamic acids at a concentration of 10(-3)m markedly inhibited the multiplication of T-strain 354 during 18 hr of incubation; this inhibition was not corrected by thymidine at a concentration of 500 mug per ml. Aurothiomalate was 20 times more inhibitory to Mycoplasma hominis DC-63 than to T-strain 354; equivalent inhibitory concentrations were 50 mug per ml for M. hominis and 1,200 mug per ml for T strains.

Metabolism of 14C-urea by T-strain mycoplasma.

When (14)C-labeled urea was metabolized by T-strain mycoplasma, 94 to 95% of the radioactivity was recovered as (14)CO(2), and significant radioactivity was not incorporated into cellular material.
