AIM Interferon-alpha (IFN-alpha) has been extensively explored for its efficacy in various disease conditions and is currently used as a standard treatment in several of these. Its use is accompanied by a wide variety of possible side effects. These side-effects may hamper reaching and maintaining the dose needed for maximal therapeutic effect while their(More)
Tamoxifen is a largely inactive pro-drug, requiring metabolism into its most important metabolite endoxifen. Since the cytochrome P450 (CYP) 2D6 enzyme is primarily involved in this metabolism, genetic polymorphisms of this enzyme, but also drug-induced CYP2D6 inhibition can result in considerably reduced endoxifen formation and as a consequence may affect(More)
Depression and cognitive disturbance are well-known neuropsychiatric side effects of therapy with interferon-alfa (IFN-alfa). Aggression and irritability are also reported as side effects. Probably, central nervous system (CNS) serotonergic dysfunction is one of the underlying pathophysiological mechanisms of IFN-alfa-induced neuropsychiatric toxicity.(More)
Immunotherapy with interferon-alpha (IFN-alpha) induces neuropsychiatric side effects, most notably depression. In hepatitis patients treated with IFN-alpha, severity of depression correlates with a decrease in serum activity of dipeptidyl peptidase IV (DPP-IV, EC, a membrane-bound protease involved in the cleavage of cytokines and neuroactive(More)
Changes in individual quality of life (IQoL) and its correlates in patients admitted to an academic palliative care unit are reported. Correlates tested were pain, fatigue, and reconceptualization (changes in content of quality of life, a measure of adaptation). IQoL was measured with a structured interview method that derives an IQoL score from evaluations(More)
The role of undiagnosed psychiatric disorders in patients requesting euthanasia is an important ethical and professional issue. From June, 1997, until June, 1999, we included a psychiatric consultation as part of our standard procedure for handling euthanasia requests. Of 22 cancer patients who requested euthanasia at short notice: ten had their(More)
OBJECTIVES The Distress Thermometer (DT) is a promising instrument to get insight into distress experienced by cancer patients. At our Family Cancer Clinic the DT, including an adapted problem list, was completed by 100 women at increased risk of developing hereditary breast cancer (mean age 45.2 years; SD: 10.5). Additionally, the women filled in either(More)
Abnormal activity in peripheral blood of the cytosolic enzyme prolyl endopeptidase (PEP, EC, post prolyl cleaving enzyme, prolyl oligopeptidase) has been found in patients with a variety of psychiatric disorders, most consistently in mood disorders. Mood disturbance is a well-known side effect of immunotherapy with interferon-alpha (IFN-alpha).(More)
Immunotherapy with interferon-alpha (IFN-alpha) induces neuropsychiatric side effects, most notably depression. One of the presumed pathophysiological mechanisms is an effect on tryptophan metabolism. As tryptophan is the precursor of serotonin, decreased availability of tryptophan to the central nervous system could result in serotonin deficiency.(More)
AIM Immunotherapy with interferon-alfa (IFN-alfa) is used in a variety of diseases in- and outside clinical trials (e.g., chronic hepatitis, melanoma, chronic myelogenous leukemia, renal cell carcinoma, multiple myeloma). Treatment with IFN-alfa can cause (severe) neuropsychiatric side effects. The purpose of this article is to give an updated review of(More)
