Some patients may experience drug fever, a marked febrile response to penicillamine, usually in the second to third week following initiation of therapy. Drug fever may sometimes be accompanied by a macular cutaneous eruption. In the case of drug fever in patients with Wilsons disease or cystinuria, penicillamine should be temporarily discontinued until the reaction subsides. Then penicillamine should be reinstituted with a small dose that is gradually increased until the desired dosage is attained. Systemic steroid therapy may be necessary, and is usually helpful, in such patients in whom drug fever and rash develop several times.. In the case of drug fever in rheumatoid arthritis patients, because other treatments are available, penicillamine should be discontinued and another therapeutic alternative tried since experience indicates that the febrile reaction will recur in a very high percentage of patients upon readministration of penicillamine.. The skin and mucous membranes should be ...

D-penicillamine is gaining increasing acceptance worldwide for the treatment of rheumatoid arthritis, despite the drugs formidable toxic potential. Most reports of adverse reactions to penicillamine have concerned its commonly encountered skin, renal, or hematopoietic toxicity. More recently, several cases of myasthenia induced by penicillamine have been described (1-3).. Our patient is 59 years old and has had active rheumatoid arthritis for more than 20 years. During the preceding year he had become progressively debilitated and developed chronic pressure sores. He was confined to bed or chair, but could stand without assistance. ...
Penicillamine is a chelating agent used in the treatment of Wilsons disease. It is also used to reduce cystine excretion in cystinuria and to treat patients with severe, active rheumatoid arthritis unresponsive to conventional therapy. Penicillamine is used as a form of immunosuppression to treat rheumatoid arthritis. It works by reducing numbers of T-lymphocytes, inhibiting macrophage function, decreasing IL-1, decreasing rheumatoid factor, and preventing collagen from cross-linking. Its use in Wilsons disease, a rare genetic disorder of copper metabolism, relies on its binding to accumulated copper and elimination through urine ...

Penicillamine is a chelating (KEE-late-ing) agent that binds to excess copper and removes it from the blood stream. In certain conditions, excess copper can build up in the blood stream, leading to tissue damage throughout the body. Penicillamine is used to remove excess copper in people with an inherited condition...

Y1 - 1991/7/31. N2 - Molecular dynamics simulations of a zwitterionic bis(penicillamine) enkephalin derivative in 1.0 M saline solution have been performed. Two simulations produced essentially the same average results although they differed in the initial random placement of the salt ions. The dynamical and structural properties from the simulations were compared with those from a previous simulation of the peptide in pure water. The properties of the sodium and chloride ions were compared with those from a simulation of bulk salt solution. An inner-sphere complex between the peptide and the chloride ions was observed in which two to three chloride ions were associated with the NH3 + terminal hydrogen atoms. Several chlorides associated with more than one amide hydrogen simultaneously, and the ...
Indian childhood cirrhosis (ICC) is an almost uniformly fatal disease whose outcome may be modified with penicillamine if given at a sufficiently early stage. Twenty nine children with ICC seen in Pune, India, in 1980-7, who had survived at least five years from onset of penicillamine treatment, were reviewed aged 6.3 to 13 years. They were assessed clinically, biochemically, histologically, and by duplex Doppler ultrasound examination. None had symptoms suggestive of liver disease. There were no toxic effects of penicillamine other than asymptomatic proteinuria. Hepatosplenomegaly reduced significantly and liver function tests returned to normal in all. In four children, significant hepatosplenomegaly was associated with an abnormal duplex Doppler hepatic vein flow pattern and micronodular cirrhosis on biopsy. Clinical findings, growth and development, and ultrasound examination were normal in the remainder. Review of serial liver biopsy specimens showed a sequence of recovery from ICC through ...

The kinetics and mechanism of Ag(I)-catalyzed exchange of coordinated cyanide in hexacyanoferrate(II) by D-penicillamine (D-PA) have been monitored by following the appearance of blue colored complex [Fe(CN)5(D-PA)]3-at 423 nm, corresponding to metal to ligand charge transfer (MLCT) transition. The effect of pH, ionic strength, catalyst concentration and concentration of hexacyanoferrate(II) and D-penicillamine on the rate of reaction has also studied and explained. The findings indicate first order dependence each in [Fe(CN)6]4- and [D-PA]. The composition of the complex formed has been established to be 1:1 by mole ratio and slope ratio method. The kinetic observations suggest that the substitution follows an interchange dissociative (Id) mechanism which proceeds via formation of a solvent bound intermediate. The activation parameters ΔH# and ΔS# have also been calculated and provided in support of the proposed mechanistic scheme. It is observed first time that the drug D-penicillamine used ...

Zinc therapy has replaced penicillamine as first-line therapy for Wilsons disease. New guidelines reflect the paradigm shift in treatment that has occurred in recent years. In the old paradigm, Wilsons disease was seen as genetic disorder associated with the accumulation of copper in the liver and in other organs once the liver had become overloaded with copper. When left untreated, the disease was regarded as uniformly fatal. The old treatment guidelines advised, decoppering with penicillamine because this chelating agent was considered effective in restoring most patients to health. Before the start of treatment, patients were warned that their symptoms could worsen during the first weeks or months of therapy, so as to prevent them from abandoning penicillamine therapy in dismay. In the new paradigm, Wilsons disease is seen as a hereditary disorder associated with copper intoxication. The essence of symptomatic Wilsons disease is poisoning by free copper in the blood, that is, by copper ...
About 20 to 30 percent of patients consuming penicillamine suffer from after effects like vomiting, diarrhea, dysgeusia or distortion of taste sense and bone marrow suppression. Slowing down the healing process in the body is another reaction to this medicine.. Apart from the above painful side-effects, she also underwent severe depression. She was admitted to the Masina Mental hospital, a rehabilitation center in Mumbai around August 2008. She was given 14 electroshocks, also known as Electroconvulsive therapy (ECT) as a part of the treatment.. When you are first diagnosed for four to five years everyone is put on penicillamine because it removes copper faster though it has side effects too much of copper in the organs can result in irreplaceable damage hence everyone is put on penicillamine, Mendonca said in an interview to Scienceworldreport.com..

The significantly increased copper and oxidative stress levels are characteristic hallmarks of cancer cells. These differences provide a unique opportunity for selective targeting of cancer cells. D-penicillamine (D-pen) has been proposed to generate reactive oxygen species (ROS) in presence of copper. Therefore, these studies were aimed at investigating the potential application of a currently marketed copper chelator, D-pen, as a novel cytotoxic anti-cancer agent. D-pen was shown to produce ROS, specifically hydrogen peroxide (H2O2), in the presence of cupric sulfate through a copper catalyzed oxidation reaction. During this process D-pen was converted to D-pen disulfide. The experimental proof of the H2O2 generation was conclusively shown with the aid of a novel High Performance Liquid Chromatography (HPLC) assay. The in-vitro cytotoxicity of D-pen co-incubated with cupric sulfate was examined in human beast cancer (MCF-7 and BT474) and leukemia cells (HL-60, HL-60/VCR, and HL-60/ADR). D-pen was
Forty-one patients (18 male and 23 female) between the ages of 6 and 54 with a diagnosis of Wilsons disease and who were intolerant of d-penicillamine were treated in two separate studies with trientine hydrochloride. The dosage varied from 450 mg to 2,400 mg per day. The average dosage required to achieve an optimal clinical response varied between 1,000 mg and 2,000 mg per day. The mean duration of trientine hydrochloride therapy was 48.7 months (range 2 months to 164 months). Thirty-four of the 41 patients improved, 4 had no change in clinical global response, 2 were lost to follow-up and one showed deterioration in clinical condition. One of the patients who improved while on therapy with trientine hydrochloride experienced a recurrence of the symptoms of systemic lupus erythematosus which had appeared originally during therapy with penicillamine. Therapy with trientine hydrochloride was discontinued. No other adverse reactions, except iron deficiency, were noted among any of these 41 ...

Triethylenetetramine [TETA (trientine); Supplemental Fig. 1] is an alternative drug for Wilsons disease if the patient becomes intolerant to the primary medication with penicillamine (Walshe, 1969). TETA is a very efficient copper chelator and very well tolerated. However, it is rapidly metabolized to its mono (MAT)- and diacetylated (DAT) derivatives (Lu et al., 2007). Recently, TETA has also shown potency in the treatment of other diseases such as diabetes-associated end-organ damage (Cooper, 2011), cancer (Yin et al., 2003), and Alzheimers disease (Cooper, 2011).. TETA resembles the biogenic polyamine spermidine (Spd) in structure (Supplemental Fig. 1), but possesses only about +2 net charge at the physiologic pH compared with +3 that of Spd (Bencini et al., 1999; Frassineti et al., 2003). The polyamines Spd and spermine (Spm) are present at high concentrations in almost all cell types and are considered mediators of important cellular functions such as proliferation, differentiation, and ...

The effect of therapeutic concentrations of D-penicillamine, sodium aurothiomalate, and levamisole on in vitro neutrophil chemotaxis and random migration in normal subjects and patients with rheumatoid arthritis was studied. D-penicillamine produced no changes. Sodium aurothiomalate produced dose-related reductions in chemotaxis in normal subjects and in patients who had a good clinical response to gold therapy, while patients who had failed to respond to gold showed a minimal nondose dependent reduction. Levamisole produced dose-dependent stimulation of chemotaxis, a greater effect found with the patients cells. Neutrophil chemotaxis improved to normal values in most patients responding to several months of D-penicillamine treatment but showed an immediate and marked stimulation in patients treated with levamisole. ...
An S-nitroso-N-acetylpenicillamine (SNAP) derivatization approach was used to modify existing free primary amines found in fibrin (a natural protein-based biomaterial) to generate a controlled nitric oxide (NO) releasing scaffold material. The duration of the derivatization reaction affects the NO release kinetics, the induction of controlled NO-release, hydrophobicity, swelling behavior, elastic moduli, rheometric character, and degradation behavior. These properties were quantified to determine changes in fibrin hydrogels following covalent attachment of SNAP. NO-releasing materials exhibited minimal cytotoxicity when cultured with fibroblasts or osteoblasts. Cells maintained viability and proliferative character on derivatized materials as demonstrated by Live/Dead cell staining and counting. In addition, SNAP-derivatized hydrogels exhibited an antimicrobial character indicative of NO-releasing materials. SNAP derivatization of natural polymeric biomaterials containing free primary amines ...
Wilsons disease (WD) is an autosomal recessive disorder with reduced biliary excretion of copper plus impaired formation of ceruloplasmin, leading to copper accumulation in the liver, brain, kidney, and cornea. Clinical manifestations include liver damage, psychiatric symptoms, and neurological features. We report a 35-year-old woman with a history of deranged liver functions who had severe depression several years later and eventually presented with parkinsonian features. The underlying diagnosis is WD and family screening revealed WD in 2 other siblings. She could not tolerate penicillamine because of fever and leucopenia. While taking trientine hydrochloride and zinc sulphate, her parkinsonism improved and her depression remained in remission. WD should be considered in patients with unexplained liver function derangement or psychiatric symptoms. Early diagnosis and initiation of specific treatment are crucial in minimising any further cerebral and hepatic damage as well as securing possible ...
Causes. An abnormal gene inherited as a recessive trait causes Wilsons disease. For people to exhibit signs and symptoms of the disease, they must inherit two copies of the gene, one from their mother and one from their father. Children wont develop signs and symptoms of the disease if they inherit the gene from only one parent. Instead, they become carriers of the disease, meaning they can pass on a copy of the mutated gene to their offspring. Siblings of people with diagnosed Wilsons disease have a one-in-four chance of carrying the same gene pattern and should be tested.. Treatment. Treatment usually continues for life and involves taking medications that help remove the deposited copper from tissues. These copper-removing medications include penicillamine (Cuprimine, Depen) and trientine (Syprine). Sometimes taking zinc supplements will help block copper absorption by the intestines.. Having this disease means youll also need to follow a low-copper diet. That means avoiding certain foods ...

Hey guys, the enzyme you are talking about is bromelain - a proteolytic enzyme (digests proteins). It is also a natural anti-coagulant as it breaks down the blood-clotting protein in your body called fibrin. Bromelain is also used to treat muscle injuries as well as being a digestive aid. When singers feel the effects of a sore throat coming on with a cold, we have them drink plenty of pineapple juice and eat fresh pineapple because bromelain also thins mucus as well as having potent anti-inflammatory properties. Bromelain enhances the effect of the digestive enzymes trypsin and pepin, thus aiding digestion. Believe it or not, it also enhances the effect of the antibiotics amoxicillin, erythromycin, penicillamine, and penicillin. And get this... in a recent study of 100 participants having urinary tract infections, ALL were cured when given bromelain with the trypsin enzyme, compared with just 46% who received antibiotics alone ...

To investigate the relationship between the nitric oxide (NO) and the endoplasmic reticulum (ER)-related cell death in human astroglioma CRT-MG cells, the cells were treated with S-nitroso-N-acetyl-D,L-penicillamine (SNAP), a NO donor and thapsigargin, an ER-stress inducer, respectively. The SNAP as well as thapsigargin increased the cytosolic Ca2+ and led to apoptosis in a dose dependent manner in CRT-MG cells suggesting NO depletes ER Ca2+. The expressions of ER-associated molecules including IRE1, p-eIF2\#945;, ATF-1 and Ero1-\#945; increased in the thapsigargin- or SNAP- treated CRT-MG cells. Among them the expression of IRE1 markedly began to increase at 12 hrs, peaked at 24 hrs, and was still persisted up to 48 hrs on the treatment of cells with thapsigargin or SNAP. Furthermore, the nuclease activity of IRE1 was also detected in the thapsigargin- or SNAP- treated CRT-MG cells. SNAP as well as the thapsigargin induced the formation of the IRE1-TRAF2 complex and the increase of expressions ...
Culture of mesangial cells (MCs) in 5.6 vs. 30.0 mmol/1 glucose for 3 weeks induced a sustained increase in protein kinase C (PKC) activity, transforming growth factor (TGF)-β1 mRNA, bioactive TGF-β, and collagen synthesis. Nitric oxide (NO), generated exogenously by the NO donor S-nitroso-N-acetyl, D,L-penicillamine (SNAP) or endogenously after the exposure of MC to interleukin-1β (IL-1β), suppressed bioactive TGF-β in MCs cultured in 5.6 or 30.0 mmol/1 glucose and suppressed or abolished increases in TGF-β1 mRNA and collagen synthesis induced by high concentrations of glucose or phorbol 12,13-dibutyrate without altering values obtained with normal glucose concentrations. SNAP had a transient suppressive effect on PKC activity, which may explain at least in part some of the actions of SNAP. The selective inhibitor of PKC, bisindolylmaleimide (GFX), mimicked NO action. The ability of SNAP and IL-lβ to suppress TGF-β and collagen synthesis was not mediated by cGMP, since the cGMP analog, ...
