The most common peripheral neuropathy associated with HIV occurs in the later stages of HIV disease, usually after the patient has had other AIDS-defining illnesses. This disorder, called predominantly sensory neuropathy PSN ; or distal symmetric polyneuropathy DSPN ; , occurs in over 30% of individuals with AIDS. Autopsy-based studies have found it in nearly 100% of patients who died of AIDS. Because the symptoms of PSN are virtually identical to those of the toxic neuropathies TN ; associated with the antiretroviral agents ddI, ddC and d4T, the two classes of neuropathy will be considered together in this article. The Diagnosis of a sensory neuropathy requires a history compatible with predominantly sensory dysfunction and a physical examination notable for abnormal sensory findings in the feet, with reduced or absent ankle jerks. Ancillary testing is required in only a minority of cases.

| Tiagabine hclTell your doctor if you have thyroid, heart, or liver problems; have diabetes, glaucoma or osteoporosis; or are pregnant or breast-feeding. If you are to receive any medical dental treatment, tell them you are taking prednisone. Long term use of steroids may be associated with a range of side effects, eg thinning of the bones, decreased resistance to infection, increased blood pressure and diabetes. Discuss your prednisone therapy with your doctor if any vaccines are recommended. Prednisone may reduce the response to some vaccines, while live vaccines like rubella, should be avoided. NOTE: Prednisone is not a sports enhancing steroid.
Half life is shorter if co-administered with enzyme inducing drugs. * Levels which should be achieved in refractory epilepsy. A higher level can be achieved without toxicity when drug is given as monotherapy. * Carbamazepine doses are lower in elderly; phenytoin dose is higher in children; Valproate dose is higher with polypharmacy. * Primidone dose in children: 2years 200-500mg day: 2-5 years 500-750 mg day: 6-9 years 0.75- 1g day Table 2. AEDs: dose, plasma half life & effective drug level Porter et al 1989 ; 47 Though monotherapy has definite advantages and is a preferred mode of therapy when treating newly diagnosed cases, polytherapy may occasionally be superior to monotherapy. Veteran's Administrative study 37 showed that 40% of the cases not controlled on monotherapy improved with polytherapy and 11% became seizure free. Mattson 36 reported that the addition of a second drug improves the seizure control in 20 to 25% of the cases with 5 to 10% of patients becoming seizure free. A further addition of a third AED further improves the seizure control in another 10% of cases. With the availability of newer AEDs Table 3 ; with lower side effect profiles, the role of polytherapy is increasingly considered in treating the cases, uncontrolled with monotherapy i.e. difficult to treat cases or refractory cases ; leading to introduction of term "Rational Polytherapy" as a system for planning treatment. channels, modification of GABA- mediated chloride conductance, elevation of GABA levels or action on Tcalcium channels.

Types expressed in the target cells Clarke and Brunner, 1996; Watanabe et al., 1997 ; . Data from clinical material are still somewhat limited and the role of ER in antiestrogen-resistant and responsiveness requires further study. One small study of nine TAM-resistant and eight responsive tumors found 2-fold higher median levels of ER versus ER mRNA expression by polymerase chain reaction in the TAMresistant biopsies Speirs et al., 1999a ; . However, protein levels were not reported. The association with TAM resistance may reflect the poor prognosis associated with ER expression Speirs et al., 1999a ; . The role of ER mutants has been most widely studied for ER . Several mutant ER genes have been reported, but the consequence of this expression is unclear. For example, it is often not known whether the mutant mRNA is translated, although some mutant ER proteins clearly are produced Murphy et al., 1998 ; . Most tumors that express mutant ER concurrently express the wildtype receptor, with the mutant representing a relatively small proportion of total ER proteins. Thus, only dominant negative mutants have a substantial chance of affecting transcription. A mutant ER that perceives TAM as an agonist has been described in some MCF-7 cell variants Jiang et al., 1992 ; . It is not clear whether this, or functionally similar mutant proteins, occur in breast tumors in patients. At least five isoforms of ER have been identified, with three full-length isoforms exhibiting the ability to bind DNA as homodimers and heterodimers with ER Moore et al., 1998 ; . A tyrosine mutant of ER has been reported, but is sensitive to the actions of antiestrogens and is likely not involved in antiestrogen resistance Tremblay et al., 1998 ; . An exon 5 deletion mutant of ER also has been reported Vladusic et al., 1999 ; . Whether this mRNA is translated, and its likely role in antiestrogen resistance, remain to be elucidated. There is little compelling evidence that ER mutant proteins directly confer resistance in a significant proportion of breast tumors Karnik et al., 1994 ; . However, it would be premature to exclude the possibility that mutated ER confer resistance in some breast cancers. It is likely that a better understanding of the role of such ER mutants, whether these be of the ER and or ER genes, will likely emerge in the relatively near future. B. Coregulators of Estrogen Receptor Action Recently, several investigators have identified coregulator proteins that can significantly influence ER-mediated transcription; for an excellent recent review, see McKenna et al. 1999 ; . These can be most easily thought of as being either coactivators increase transcription, e.g., SRC-1 ; Xu et al., 1998 ; or corepressors inhibit transcription, e.g., N-CoR, SMRT ; Jackson et al., 1997; Soderstrom et al., 1997 ; . Binding of the SRC family of proteins is mediated by a conserved LXXLL motif that facilitates interactions with ligand-occupied ER Ding et and tiagabine.

Finally, case reports of patients with severe psychiatric disorders reported clear benefits from the addition of tiagabine.37 In one patient, with schizoaffective disorder manic type ; tiagabine 8 mg daily was added as an adjunct to paroxetine and olanzapine. The adjunctive tiagabine successfully controlled paranoid features that appeared when the patient In preclinical studies, gabapentin was shown to have anxiolytic effects stopped taking lamotrigine. Two other patients in this case report and similar to those of diazepam, but did not produce the memory-impairing two patients in another report presented with severe, uncontrolled effects of the latter drug.21 Gabapentin has also been shown to be benmania mixed mania, with and without mood-congruent psychosis in eficial in clinical studies of patients with panic disorder the second report ; were reported to benefit from the addi PD ; , 20 social phobia SP ; , 18 obsessive-compulsive disorder tion of tiagabine to ongoing mood stabilizer and antide OCD ; , 23 and PTSD.24 In a randomized, double-blind, pressant treatment. Tiagabine treatment was followed by Tiagabine placebo-controlled, parallel-group study, 69 patients with complete remission of bipolar symptoms.33, 38 One patient SP were randomly assigned to gabapentin or placebo for is the only began to experience a manic episode at 3 mg day tiagabine, 14 weeks.19 A significant reduction p 0.05 ; in the sympbut these symptoms resolved after the dose was raised to currently available toms of SP were seen in patients on gabapentin compared 4 mg day. with placebo. The adverse events reported were consistent selective with the known side-effect profile of gabapentin. A small-scale European trial evaluated the use of GABA-reuptake tiagabine in eight patients with acute mania.39 The Various case reports have appeared in which gabapentin has inhibitor patients received higher initial doses 20 mg daily ; and a been reportedly useful in PTSD 22 and refractory PD, OCD, SGRI ; . more rapid titration than is typically employed 5 mg per and GAD.26 One case report described 18 patients with a day until limiting side effects occurred or 40 mg daily is variety of serious psychiatric illnesses and comorbid anxiety reached ; . Three patients with moderate mania showed disorders. Gabapentin was administered for up to 38 slight improvements, but none of the patients with severe months.25 Fifteen patients were treated for at least 12 months. mania showed a clear benefit. The authors suggested that The authors found that the anxiolytic effects of gabapentin tiagabine may not be effective as acute therapy for mania, were sustained over several months in most patients, with no but recommended further research on the drug as a mood evidence of tolerance or physical dependence after abrupt stabilizer. discontinuation. In these 18 patients, the most common adverse effects were drowsiness and dizziness during initiation of treatment. This is consistent with the literature, which indicates that gabapentin is generally well tolerated; the most common adverse effects include somnolence, dizziness, ataxia, fatigue, and weight gain.27 Tiagabine potentiates CNS GABAergic function through its unique ability to inhibit GABA reuptake at the GAT-1 GABA transporter. Tiagabine is the only currently available selective GABA-reuptake inhibitor SGRI ; . Tiagabine increases the amount of available extracellular GABA by up to 200%, 28 without perturbing normal physiologic control and without increasing total brain GABA. Some researchers have speculated that this unique mechanism of action may result in fewer adverse effects compared with other GABA-enhancing mechanisms.14, 29 Three major mood stabilizers, lithium, carbamazepine, and valproate, share GABAergic effects at GABA-B receptors and or on GABA turnover ; as one possible common mechanism for mood stabilization. The GABAergic activity of valproate is believed to be an important mechanism underlying both its anticonvulsive and mood-stabilizing effects.40 Recent work conducted at Yale University not yet published ; suggests that unipolar patients have mean plasma GABA levels that are only 50% of those of normal volunteers; these rise to 100% with SSRI treatment. They also reported that depressed bipolar patients, in contrast to non-bipolar depressives, have near-normal GABA levels, which become significantly higher than normal as clinical improvement occurs and tolmetin.
