Multiple mutations will cause this drug to lose its effectiveness. Side effects include diarrhea and nausea.

Antidepressants: Antidepressants including MAOIs, tricyclic antidepressants and SSRIs ; may have the potential to inhibit the metabolism of valproate via the cytochrome P450 system. However, there is not expected to be any significant interaction within normal therapeutic doses. Antidepressants can lower the seizure threshold of non-stabilised epileptic patients, and so careful and regular monitoring of their condition is indicated. Clozapine: Caution is advised during concomitant administration as competitive protein binding may potentiate an increase in clozapine or valproate levels. Chlorpromazine: Chlorpromazine may inhibit the metabolism of valproate. Fluoxetine: Fluoxetine may inhibit the metabolism of valproate as it does with tricyclic antidepressants, carbamazepine and diazepam. Mefloquine: Mefloquine increases valproic acid metabolism and has a convulsing effect; therefore epileptic seizures may occur in cases of combined therapy. Cimetidine or Erythromycin: Valproate serum levels may be increased as a result of reduced hepatic metabolism ; in case of concomitant use with cimetidine or erythromycin. Carbapenem antibiotics: Decreases in valproate blood level sometimes associated with convulsions has been observed when valproate and carbapenem antibiotics panipenem, meropenem, imipenem, ertapenem, biapenem ; were combined. If these antibiotics have to be administered, close monitoring of valproate blood levels is recommended. Cholestyramine: May decrease the absorption of valproate. Interference with Clinical Laboratory and Other Tests Epilim is eliminated mainly through the kidneys, partly in the form of ketone bodies. This may give false positives in the urine testing of possible diabetics. There have been reports of altered thyroid function test results associated with sodium valproate. The clinical significance of this is unknown. Effect on Ability to Drive or Operate Machinery Use of Epilim may provide seizure control such that the patient may be eligible to hold a driving licence. However, patients should be warned of the risk of transient drowsiness, especially in cases of anticonvulsant polytherapy, too high a starting dose, too rapid a dose escalation or association with benzodiazepines and imovane.

EDUCATIONAL OBJECTIVE: At the conclusion of this presentation, the participants should be able to discuss the viral etiologies of vocal cord paralysis and the unique clinical characteristics and diagnostic criteria of West Nile virus infection. OBJECTIVES: West Nile virus has recently become a public health concern in the United States, after an outbreak in New York City in 1999. The virus may cause a spectrum of disease from flu-like symptoms to encephalopathy, muscle weakness, and, in some cases, death. We report a unique patient who developed a permanent vocal fold paralysis as a direct result of infection with the West Nile virus. STUDY DESIGN: Case report. METHODS: A 69 year old man presented in August 1999 with a one week history of severe, progressive muscle weakness. The patient's clinical course, diagnosis of West Nile virus and two year follow-up will be discussed. RESULTS: After admission to the intensive care unit, the patient developed hoarseness and was unable to maintain adequate respiratory volumes secondary to muscle weakness. Fiberoptic examination revealed bilateral vocal cord paralysis. The patient was intubated for ventilatory support due to his inability to maintain adequate tidal volumes secondary to a combination of respiratory muscle weakness and vocal fold paresis. Positive West Nile virus infection was documented on cerebrospinal fluid analysis. The patient subsequently required tracheotomy placement. After a prolonged hospital course, the patient was discharged to a nursing home with the tracheotomy tube in place. Two years later, the patient had recovered right vocal fold function, but the left vocal cord paralysis persisted. CONCLUSIONS: West Nile virus is now a nationally reportable disease and a major public health concern. Our case illustrates the importance of the inclusion of West Nile virus in the differential diagnosis of hoarseness, particularly in the background of flu-like symptoms and progressive muscle weakness. In addition, it underscores the need to examine the vocal folds if a tracheotomy is required in a patient with documented muscle weakness.

Characterized by fever, rash, eosinophilia, lymphadenopathy, pharyngitis, and malaise. It typically develops between 2 and 8 weeks after starting therapy but can occur after 12 weeks or longer.

Thematous eruption to more serious SJS or TEN. The liver is the most frequently involved internal organ in anticonvulsant HSR, although other organs such as the kidney eg, interstitial nephritis, vasculitis ; , central nervous system eg, encephalitis, aseptic meningitis ; , heart eg, myocarditis ; 44 ; or lungs eg, interstitial pneumonitis, respiratory distress syndrome, vasculitis ; 45, 46 ; may be involved 47 ; . In some patients, extensive organ involvement evolves as part of the anticonvulsant HSR. For example, a woman developed skin rash, fever and eosinophilia three weeks after starting carbamazepine. Fulminant respiratory and renal failure ensued. Autopsy showed pneumonitis, nephritis, serositis, pancreatitis, hepatitis and carditis 48 ; . A small subgroup of patients may become hypothyroid, as part of an autoimmune thyroiditis, within two months of initiation of symptoms 49 ; . HSR has been associated with the aromatic anticonvulsants, namely phenytoin, phenobarbital and carbamazepine 30, 47, 50-56 ; and lamotrigine 28, 57-60 ; . In many of the case reports, the hypersensitivity syndrome is often not recognized or diagnosed as an entity. In fact, the adverse event is likely to be reported as either the most prominent or most severe organ manifestation. For example, there are a large number of cases in the literature that have been termed `hepatotoxicity', yet closer investigation of these cases reveals that a rash and fever were also evident, heralding a diagnosis of HSR 61-65 ; . It has been suggested that the formation of toxic metabolites by phenytoin, carbamazepine and phenobarbital may play a pivotal role in the development of the HSR Figure 1 ; 30, 66 ; . Phenytoin, carbamazepine and phenobarbital are metabolized by cytochrome P450 to an arene oxide metabolite. This metabolite is usually detoxified by epoxide hydrolase; however, if detoxification is defective, the toxic metabolite may act as a hapten and initiate an immune response, or cell necrosis or apoptosis. In one study, 75% of a series of patients with anticonvulsant HSR to one aromatic anticonvulsant showed in vitro cross-reactivity to the other two 30 ; . Clinically, this correlated with a cross-reactivity rate of 75%. In addition, in vitro testing has shown that there is a familial occurrence of hypersensitivity to anticonvulsants, with an autosomal pattern of inheritance 30, 67 ; . A recent paper described four children who manifested symptoms of HSR with carbamazepine. In three patients, the syndrome was exacerbated after conversion to another aromatic anticonvulsant. Discontinuation of the aromatic anticonvulsant resulted in resolution of symptoms; valproic acid was well tolerated in three patients who required continued anticonvulsant therapy 68 ; . Diagnosis is dependent on clinical recognition and judgment. The lymphocyte toxicity assay is expensive and cumbersome to perform; it is only used in certain research centres 69 ; . Some studies have evaluated the usefulness of patch testing in the diagnosis of anticonvulsant HSR 70-75 ; . However, most of the studies have shown inconsistent results. For example, in five patients with systemic symptoms, oral challenges were performed with positive results; two of these patients had negative patch tests 72 ; . If patch testing is to be carried out in these patients, 1% or 10% carbamazepine Can J Clin Pharmacol Vol 6 No 3 Autumn 1999 and valacyclovir.

Grossman et al. [39] recently reported the survival of 368 patients with newly diagnosed glioblastoma treated with investigational new drugs either prior to or following radiotherapy. In their study, no significant difference in survival was detected between the two groups. However, the authors stressed that careful monitoring of tumour progression in patients treated with new agents prior to radiotherapy is mandatory to avoid delaying salvage radiotherapy. In our study, we observed slightly higher progression-free and overall survival rates in group B patients, which could either be due to the effectiveness of radiotherapy or to selection bias that excludes patients with rapidly progressing tumours from receiving radiotherapy. In the absence of postoperative randomisation, it was impossible to compare groups A and B, although both had very similar survival outcomes. Medications commonly used by patients with malignant gliomas corticosteroids, phenytoin, carbamazepine and phenobarbital ; affect the CYP3A4 enzyme system [26, 4045], cause an increase in the clearance of paclitaxel [40] and irinotecan, and require the use of larger doses of chemotherapy [4245]. In our study, the clearance of irinotecan was increased in four of five patients exposed to phenobarbital or carbamazepine, corroborating previous studies [46]. Interestingly, valproic acid is also registered for seizure prevention and does not interact strongly with the CYP3A4 enzyme. Valproic acid is conjugated in humans, reversibly inhibits hepatic UGT1A1 conjugation, both by competitive and noncompetitive mechanisms [46, 47], and interacts with drugs requiring glucuronidation [48]. In addition, valproic acid and its metabolites exert choleretic effects in animal models [49]. In Wistar rats, concomitant administration of valproic acid 200 mg kg with irinotecan 20 mg kg inhibited SN-38-G formation and increased AUCSN-38 by 270% as compared with control rats receiving irinotecan alone [19]. Therefore, valproic acid was expected to result in increased SN-38 exposure and intestinal toxicity in humans. However, our study shows that valproic acid did not increase the rates of diarrhoea and neutropenia as compared with previous studies in patients treated without anticonvulsants [30, 31]. In previously published pharmacokinetic data from phase I II studies in patients without brain tumours [5053] Table 4 ; , we found that in patients without gliomas the mean clearances of irinotecan ranged from 11.0 to 21.1 l h m2 Table 4 ; . In our study, the clearance of patients receiving valproic acid 17.2 l h m2, range 9.527.5 ; appears to be similar to that observed in patients treated without anticonvulsants 14.2 l h m2, range 12.416 ; . In our study, the exposure to SN-38 471.6 224.3 ngh ml ; was comparable with that previously reported by Abigerges et al. [50] and Rivory et al. [54] in phase I trials using similar doses of irinotecan. This is in contrast with the study by Friedman et al. [26] where the clearance of irinotecan in patients receiving phenytoin, carbamazepine and or phenobarbital was 30.4 8.3 l h m2 and was correlated with low exposures to SN-38 and SN-38-G. Based on our data, the glucuronidation of SN-38 did not seem to be completely inhibited in patients treated with valproic acid. Discrepancies between species might explain the absence of drug interactions between valproic acid and irinotecan in humans. In addition, we have recently shown that concomitant medications with valproic acid generate new metabolites by oxidation of the camptothecin backbone or the piperidinylpiperidine lateral chain of irinotecan [25]. Other factors that might help to explain the absence of inhibition of UGT1A1 in humans might be related to the schedule of dosage of valproic acid. In humans, valproic acid was given as a chronic daily oral administration starting several days before irinotecan, while in animal experiments a single i.v. valproic acid infusion was given immediately before the administration of irinotecan. Finally, chronic oral corticosteroids might help to counteract the effects of valproic acid by inducing UGT1A1 enzymes. In summary, irinotecan 350 mg m2 every 3 weeks ; has an effect that results in a median time-to-progression of 9 weeks in group A and 14.4 weeks in group B, with 6-month progressionfree survival rates of 26% and 43% in groups A and B, respectively. The toxicity profile of irinotecan requires careful clinical follow-up in patients with glioblastoma. We showed that valproic acid does not increase the exposure to SN-38 and the toxicity of irinotecan in patients with glioblastoma. Although the response rate of irinotecan as a single agent was limited, it remains an attractive drug for use in combination with nitrosourea, temozolomide and radiotherapy in patients with glioblastoma.
