A 68 year old man with rheumatoid arthritis developed marrow aplasia during D-penicillamine treatment. Recovery of granulopoiesis and erythropoiesis was ineffective with features of a secondary sideroblastic anaemia. Absence of megakaryopoiesis persisted. Therapeutic measures failed, and the patient finally died. These events illustrate a haematopoietic stem cell injury induced by D-penicillamine.
Although in common use, there is still controversy as to the way in which gold and penicillamine act in rheumatoid arthritis (RA). In this study, synovial fluids from 4 groups of patients have been compared: (1) RA patients on gold/penicillamine, (2) RA patients on non-steriodal anti-inflammatory drugs (NSAID) only, (3) osteoarthritis patients, and (4) patients with sero-negative arthropathies....
Two spectrophotmetric methods based on combined redox - ligand exchange reactions were developed for the determination of captopril and penicillamine in pure form and in their dosage forms. The first method is based on attenuating the absorbance of a ternary complex: silver (I) - bromopyrogallol red - phenanthroline in a buffer solution of pH6-8. The method has the concentration ranges 2-10 μg ...
Correspondence Failure of D-penicillamine to affect peripheral joint involvement in ankylosing spondylitis or HLA B27-associated arthropathy Sir, We have treated 7 patients with peripheral joint involvement in ankylosing spondylitis or HLA B27-associated arthropathy with D-penicillamine and all failed to show improvement. D-penicillamine has been shown to help peripheral joints in rheumatoid ar...
A spectroscopic investigation of the complexes formed between the Pb(II) ion and D-penicillamine (H2Pen), a chelating agent used in the treatment of lead poisoning, was carried out on two sets of alkaline aqueous solutions with CPb(II) ≈ 10 and 100 mM, varying the H2Pen/Pb(II) molar ratio (2.0, 3.0, 4.0, 10.0). Ultraviolet-visible (UV-vis) spectra of the 10 mM Pb(II) solutions consistently show...
