Therapy of Wilson's disease continues to evolve. In 1997, zinc acetate was added to the list of drugs approved by the Food and Drug Administration, which includes penicillamine and trientine. The mechanism of zinc's anticopper action is unique. It induces intestinal cell metallothionein, which binds copper and prevents its transfer into blood. As intestinal cells die and slough, the contained c...

Adult human articular cartilage has been maintained in organ culture for 8 days, and the culture medium, which was changed on alternate days, was pooled. Normal and rheumatoid cartilage was obtained from patients and 4 types of culture were prepared: (1) cartilage alone; (2) cartilage + D-penicillamine; (3) cartilage + homologous synovium; (4) cartilage, synovium, and D-penicillamine. The hexos...

Elastosis perforans serpiginosa (EPS) is a rare reactive perforating dermatosis that is characterized by the transepidermal elimination of abnormal elastic fibers. Penicillamine, which is one of the clear triggers for EPS, is a heavy metal chelator that is primarily used for disorders such as cystinuria and Wilson's disease. It may cause alterations in the dermal elastic tissue such as pseudo-p...

introduction: the wilson disease is an autosomal recessive disease in which the liver, central nervous system, eyes, blood and other parts of the body involved. timely diagnosis and appropriate treatment of the disease requires awareness of the clinical presentations of this disease in children.methods: this case series study included 62 patients with wilson disease who admitted to children&apo...

In view of promising, but uncontrolled, reports of the use of D-penicillamine in active chronic hepatitis, a randomised, prospective, controlled trial of this drug against prednisone was carried out. Of the 35 patients entered, 18 received D-penicillamine (increasing to 1-2 g daily) and 17 prednisone (15 mg daily). In all patients the disease had already been brought under biochemical control w...

The clinical manifestations of Wilson's disease are believed to be due to the accumulation of toxic amounts of copper within the body. The primary aim of treatment is to remove these, usually by giving chelating agents that will combine with the copper and be excreted in the urine. The most effective of these therapeutic agents is penicillamine (Walshe, 1960), and clinical improvement follows i...

OBJECTIVES To evaluate the duration of treatment and the reasons for discontinuing therapy with disease modifying antirheumatic drugs in Spanish rheumatoid arthritis patients. METHODS An observational study was made of 629 patients with rheumatoid arthritis treated with disease modifying antirheumatic drugs between 1979 and 1991. The outcomes (treatment termination because of toxicity and lac...

Peroxynitrite-induced relaxation of isolated vessels may involve the formation of S-nitrosothiols. This study characterized the hemodynamic effects of systemically injected peroxynitrite in pentobarbital sodium-anesthetized rats and determined whether these effects were due to the formation of S-nitrosothiols. We utilizedl-penicillamine, which attenuates the hemodynamic effects of systemically ...
