Clozapine

Obesity is highly prevalent among patients with schizophrenia. This issue needs to be addressed seriously. The different types of antipsychotic medication being prescribed appear to have different effects on WC. Patients treated with atypical antipsychotics, clozapine and olanzapine, had high.

Relapse is usually measured in weeks rather than hours or days. Sudden relapse is rare. Moreover, relapse progresses through stages that give ample warning.95, 96 Intervention becomes possible if one recognizes the relapse prodrome, particularly worsening psychosis with poor sleep and anxiety.97 If it appears that a patient's psychosis is worsening, a trial of supplemental benzodiazepines such as diazepam ; might help stave off full syndromal relapse.98 Most hospitalizations are short enough that in the vast majority of cases nothing adverse is likely to happen if the patient does not take a prescribed psychotropic during the hospital stay. The most important concern is to complete the medical surgical intervention. A thoughtful review of medications should help in deciding which ones to hold and which ones to restart in order to avoid withdrawal effects ; . Applicable maxim: Recognize when the specter of "imminent decompensation" is raised. "This patient wants to leave against medical advice. He can't smoke." Nicotine dependence deserves special mention, as "no smoking" policies are an area of contention for hospitalized smokers.99, 100 This is particularly true for patients with schizophrenia, who, as a group, are more likely to smoke and to be heavy smokers, compared to those without schizophrenia.101 Apart from its health-related effects, smoking affects the metabolism of many psychotropics. The tar products in cigarettes and not the nicotine itself ; are inducers of the P450 isoenzyme 1A2.102 Enforced abstinence could in theory lead to increased drug levels for medications metabolized through this isoenzyme. This effect is likely to be relevant only for long hospitalizations, as the "rebound" of the system like the induction ; takes several weeks. In those cases, drug toxicity e.g., for clozapine ; can develop.103 In general, the 1A2 system is "revved up" in smokers, and higher doses of medications metabolized through the P450 system such as haloperidol ; are required for smokers than for nonsmokers.104 In addition, smoking seems to contribute to hyponatremia.88 Several of the patients seen in our psychiatric consultation service wanted to sign out of the hospital because of smoking bans. A flexible approach to this problem usually worked: as unprofessional as this might seem, accompanying a patient for a smoking break went a long way. The patient felt supported and was able to stay in the hospital and receive the needed surgical intervention. An overly restrictive or legalistic view of the problem can thwart the.
Of the University of Pittsburgh will assess the feasibility and effectiveness of a three-month behavioral weight control program for patients treated with clozapine. Although clozapine represents a significant advance in the treatment of schizophrenia, it can cause significant weight gain in patients. This program involves modest caloric restriction and emphasis on regular physical activity. The data from this study will be used to support a larger study with the goal of working toward the development of a comprehensive treatment program.
Fluoxetine. Fluoxetine may inhibit the metabolism of sodium valproate as it does with tricyclic antidepressants, carbamazepine and diazepam. Chlorpromazine. Chlorpromazine may inhibit the metabolism of sodium valproate. Clozapine. Caution is advised during concomitant administration as competitive protein binding may potentiate an increase in clozapine or valproate levels. Mefloquine: Mefloquine increases valproic acid metabolism and has a convulsing effect, therefore epileptic seizures may occur in case 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.

Running title: Role of the C-terminus in ion movement by the KCCs oocytes. Additional experiments were carried out here to determine whether the effect of PMA differs between the isotonic and hypotonic conditions by preincubating oocytes for 15 min in medium L panel A ; or LH panel B ; with increasing amounts of PMA or 4-PMA from 0.0 to 1.0 M ; . Results are shown in Fig. 7 expressed as background-subtracted furosemide-sensitive, bumetanide-insensitive 86Rb + FRs normalized to those measured with "0" M PMA or "0" 4 -PMA. In both panels, a [PMA]-dependent decrease in carrier activity is observed but the kinetics of this effect appears to differ between the conditions. Indeed, a plateau begins to appear at ~0.3 M in panel A but at ~0.5 M in panel B, and apparent Ki PMA ; s based on a threeparameter Hill equation ; are 0.11 M and 0.32 M, respectively. Under either condition, importantly, 86Rb + FRs are seen to be nearly unaffected by an inactive analogue of PMA, 4-PMA. These findings indicate that the mechanisms by which PMA exerts its effect may differ between the two conditions but that the observed inhibition is probably accounted for by changes in kinase activity at the cell membrane. Effect of PMA on wt and mutant KCC2s under low Cl- isotonic vs. low Cl- hypotonic conditions. To determine whether PMA leads to changes in KCC2wt activity by promoting direct PKC-carrier interactions or by inducing other regulatory events, and whether it exerts its effect through the same mechanisms with medium LH vs. L, we repeated part of the experiments described above using 6 different mutants in which putative cytosolic PKC sites were removed, either a single site per mutant or all of the sites together. Results are shown in Fig. 8 for a [PMA] of 0.5 M and are expressed as phorbol ester-induced % decreases in furosemidesensitive, bumetanide-insensitive 86Rb + FRs. When the preincubation is carried out in medium LH panel A ; , both the wt and mutant KCCs are seen to behave analogously that is, their transport activity decreases by more than 30% with PMA. When, on the other hand, preincubation is carried out in medium L panel B ; , two of the mutants are found to become paradoxically more sensitive to the inhibitory effect of PMA, that is, their transport activity decreases by over 50%. These results suggest that the PMA effector involved in carrier inhibition does not produce its effect via canonical PKC sites. They also suggest that residue 940 or the region in which it occurs ; could play an important role under isotonic conditions by defining the accessibility of other sites to PMA-dependent effectors. DISCUSSION In the current study, we have used a mutagenic approach to identify important functional domains and residues in the putative Ct of the Na + -independent group of CCCs. More specifically, we have determined the role of three protein segments in this domain by analyzing a series of KCC2-KCC4 chimeras in which. Provide material for culture and sensitivity studies. Antimicrobials should be given for a minimum of 10-14 days. Twenty per cent of patients remain culture positive after seven days' treatment. If the patient is not fully recovered after ten days treatment, a further week of therapy is indicated 21 ; . Decongestants, Antihistamines and Steroids Oral decongestants do not significantly increase the size of the ostia. Topical agents such as oxymetazoline, xylometazoline and phenylephedrine shrink the nasal mucosa, improve drainage and provide symptomatic improvement. However, by reducing blood flow to the mucosa, they reduce the penetration of antibiotics, reduce ciliary motility and hamper clearance of infected material 7, 22 ; . Their overall effect on the clinical course and eventual outcome is unknown. If used at all, it should only be for the initial 24-48 hours. Ephedrine and xylometazoloine are least harmful to the cilia. Local agents should preferably be used as sprays, and in the erect posture. If drops are used, they should be instilled in a position with the head dependant, i.e., hanging over the edge of a bed, or with the patient on elbows and knees with the vertex touching the floor. This prevents immediate drainage of the medication into the pharynx 5 ; . Antihistamines produce inspissations of secretions and are probably harmful. Topical steroids provide rapid relief of pain but are otherwise ineffective. Antral Puncture Antral puncture is reserved for certain specific situations Table I ; . It generally done under general anesthesia in children and sertraline. Sults must be seen in this dim light. For example, symptom levels were only slightly lower on clozapine 79.1 vs. 83.6 on the Positive and Negative Syndrome Scale of Schizophrenia p 0.02 ; . Two questions arise: 1. Is this a clinically significant difference? 2. Even though the difference is minute, would it exist at all if the raters could not distinguish readily between clozapine and haloperidol patients because of their different side effects i.e. the trial was not really blind ; ? I would suggest that the answer to both questions is a resounding no. Although differences were claimed on the basis of statistical significance there were no clinical differences in either positive symptoms mean score on clozapine 19.5 vs. 21.2 on haloperidol, p 0.04 ; or, most surprisingly, on negative symptoms 20.9 vs. 21.2, p 0.02 ; . These are remarkable findings for a drug that is supposed to be effective in treatment-resistant patients. The symptom results also showed that there were 163 clozapine patients at 12 months i.e. 79.5% of those that started the trial ; and 159 haloperidol patients 72.9% ; which makes the claim, above, that more clozapine patients could continue treatment for the entire year look odd. It is explained by digging further and discovering that patients who stopped haloperidol were continued on other antipsychotics and included in the results, above, on symptoms.The patients who crossed over to another drug and completed one year of therapy differed and then only slightly ; in only one aspect from clozapine patients quality of life. That is, there was no difference in positive or negative symptoms between patients who completed one year so it is finally there in black and white its not clozapine that makes more people better, its staying on treatment.Therefore one could assume, until this is tested, that reducing extrapyramidal side effects virtually the only adverse effect that haloperidol has ; makes people better and any drug that does that will suffice. This seems to be exactly what every study is currently showing. The authors also stated that significantly more clozapine patients had a clinically important improvement in symptoms defined as a 20% or greater reduction in symptoms ; but buried the data supporting this assertion in their discussion. Easy to see why when the results are dragged out of the text 24% of clozapine patients had clinical improvement after 6 weeks vs. 13% haloperidol patients ; but after one year 37% of clozapine patients had clinical improvement as did 32% of haloperidol patients. That is, the much trumpeted gain occurs early; dare I suggest when the reduced extrapyramidal effects of clozapine are being experienced by the patient and seen by the rater e.g. less akathisia. Olanzapine 7, LY170053 ; 16, 17 is a novel atypical antipsychotic with similar binding profile as clozapine Table 1.1 ; . In studies of schizophrenic patients, 18 olanzapine was demonstrated to be effective in the treatment of both negative and positive symptoms with few EPS. Additionally, the potency of olanzapine in reversing the effects of d-amphetamine was greater, as compared to clozapine.16 The reversal of the inhibitory effects of d-amphetamine on A10 cells [Figure 1.1] has been hypothesized to be predictive of clinical antipsychotic efficacy ; .19 These findings are consistent with the fact that olanzapine is a DA antagonist in vivo, 17 and is more potent at DA D2 receptors17 in vitro, as compared to clozapine Table 1.1 and prochlorperazine.

Increasing by the fifth week to 2.73 109 L. At this time, Mr D began to show signs of relapse of his paranoid schizophrenia and was commenced on risperidone. Eight weeks following discontinuation, the neutrophil count was 2.93 109 L. This case is uncharacteristic of the usual picture of clozapine-associated neutropenia, which occurs much earlier after clozapine initiation, has a more rapid recovery time, and has been associated with eosinophilia or elevations in the WCC that might predate the neutropenia. The primary etiological role of clozapine appears likely given the gradual resolution of the neutropenia upon cessation of clozapine. Further, there was no discernible evidence for a physical cause of the neutropenia. The role of concomitant medication, especially valproic acid, remains unclear. This case confirms the necessity for ongoing hematological vigilance in patients taking clozapine!

Related Articles, Links Summary: OBJECTIVE: To review the published literature on serious adverse cardiac events associated with the atypical antipsychotic agent, clozapine, and to make recommendations for cardiac assessment of candidates for clozapine treatment and for monitoring of cardiac status after treatment is initiated. DATA SOURCES: We searched the PubMed and MEDLINE databases for articles published from 1970 to 2004 that contain the keywords "clozapine and myocarditis, " "clozapine and cardiomyopathy, " "clozapine and cardiotoxicity, " "clozapine and sudden death" or "clozapine and mortality." We also manually searched the bibliographies of these articles for related sources. STUDY SELECTION: We reviewed the 30 case reports, case series, laboratory and clinical trials, data mining studies, and previous reviews identified by this search. DATA SYNTHESIS: Recent evidence suggests that clozapine is associated with a low 0.015% to 0.188% ; risk of potentially fatal myocarditis or cardiomyopathy. The drug is not known to be independently associated with pathologic prolongation of the QTc interval, but it may contribute to pathologic QTc prolongation in patients with other risk factors for this condition. Conclusions: The low risk of a serious adverse cardiac event should be outweighed by a reduction in suicide risk for most patients taking clozapine. We provide recommendations for assessing and monitoring cardiac status in patients prior to and after initiation of treatment with clozapine and clomipramine.

Not all reports suggest that CAS outcomes are necessarily comparable to CEA in terms of post-procedural stroke. Mathur et al. 1998 ; reported the 30-day risk for stroke or death to be 7.7% overall and complication rates were found to be similar in patients with symptomatic and asymptomatic stenoses. In patients under the age of 80, the 30-day risk for stroke and or death was reported to be 5.6% while in patients over 80 years of age it jumped to 19.2%. Advanced age, presence of long or multiple lesions and severe stenosis were all identified as significant predictors of procedural strokes following carotid stenting Mathur et al. 1998 ; . It should be noted that, in patients who met NASCET criteria, the incidence of stroke and or death within 30 days of CAS was 2.7%. In a recent study, advanced age OR 1.06 ; , history of hemispherical TIA OR 4.7 ; and history of stroke OR 8.0 ; were reported to be predictive of 30-day complication rates associated with CAS Kastrup et al. 2005 and olanzapine. Maximal oxygen uptake VO2max ; was determined on a treadmill in 2 groups at 3510 m, PB 495 Torr, in chronic hypoxia. The Sajama Group SG ; were 7 healthy male mountain guides, Aymara natives Age: 32.2 5.7 ; born and living in the Sajama village at 4200 m. The La Paz group LP ; were 17 healthy Aymara male natives Age: 21.3 6.5 ; of the Bolivian army, born and living in La Paz 3500 m ; . Hematocrits and weights were not significantly different. ECG, VE , PEO2 , PE C O SaO2 were measured on-line in a computerized system that calculated VO2, VCO2 and RQ. The results show that the SG maintained the resting level SaO2 during the first 3 stages of exercise 90.0% TO 89.3% ; , whereas in the LPG, SaO2 progressively dropped. Furthermore, the SG has significantly lower oxygen consumption and carbon dioxide production than the LPG at every stage p 0.0001 ; . The SG ascended in 7 hours from 4300 m to 6542 m, prepared the soccer field, played 40 minutes intensely and returned to celebrate to the Sajama Village, all in 16 hours. In conclusion, the Sajama Group maintains a level of saturation equal to the value at rest during the initial stages of exercise and also consumes significantly much less oxygen than the La Paz control group. This remarkable work capacity at extreme altitude with complete cardiopulmonary, metabolic, genetic and phenotypic adaptation, made possible their extraordinary performance of soccer at 6542 m on the plateau summit of the Sajama Mountain, the highest in Bolivia.

The choice of appropriate anthelminthic drug for use in a control programme depends on safety, therapeutic effect efficacy ; , spectrum of activity, local health policy, and financial considerations. Other important issues to consider are the accessibility--including drug delivery--and acceptability of treatment, and possible integration with other control programmes. The possibility of drug resistance should also be carefully monitored when periodic chemotherapy is considered. With these factors in mind, the choice of anthelminthic drug for public health use should be tailored to the local epidemiology of soil-transmitted helminth infections. Information should be collected on prevalence and intensity of helminth infections, on population groups at highest risk of morbidity, and on the health impact of helminth infections in the community to be treated. This information should be used as the rationale for local health planners to choose the most appropriate anthelminthic drug and should be the backbone of a successful chemotherapy-based control programme Albonico, Crompton & Savioli, 1999.

Despite this, some studies have shown that chronic administration of atypicals can block the effects of NMDA antagonists such as ketamine. For example, repeated chronic administration of olanzapine for 7 days, but not haloperidol, reversed the impairment caused by PCP, an NMDA antagonist similar to ketamine Enomoto et al., 2005 ; . A study by Sams-Dodd 1996 ; also showed that chronic clozapine treatment inhibited PCP-induced stereotypical behaviour and social isolation. This phenomenon is also seen in the clinical situation, where antipsychotics can take a considerable length of time up to 6 weeks ; to start resolving symptoms. We therefore speculate that chronic clozapine administration may also lead to normal freezing behaviour, perhaps through changes in neural plasticity, for instance through the desensitisation of D2 autoreceptors Giardino et al., 1991; Reuss and Unsicker, 2001 ; . In addition, chronic treatment with typical antipsychotics such as haloperidol may not lead to desensitisation of D2 receptors, but instead lead to unwanted ; decreased sensitivity of D1 receptors Imperato et al., 1994; Reuss and Unsicker, 2001. By Dr. Richard F. Gottier The 39 books of the Old Testament, though written over many centuries, follow an amazingly coherent theme: God's covenant call upon one man and his descendants. The offspring of Adam soon degenerated to a godless generation, whose every thought was only evil continually. The generations born to Noah proved to be yet more defiant to God. At this point, God reached down into Mesopotamia and chose a man from whose seed He would develop a holy people. Their task was to be a `light to the nations' Isa. 42: 6 ; , evidence that God is righteous and good, worthy of our praise and worship. God's words to Abraham were straightforward: if he would walk blamelessly, obediently before Him, He would bless him with the land where he dwelt, bless his offspring bountifully, and establish an eternal covenant with his seed Gen. 17: 1 ; . The nature of God's covenant is emphasized repeatedly, `All the Land which you see, I will give it to you and to your descendents forever' Gen. 13: 15 ; . Forever! God also promised to bless all who would bless Abraham and curse those who reviled him. And through Abraham's descendants all families on earth would be blessed Gen. 12: 2-3 ; . Moses summarized the essential points of this covenant with Abraham: `If you will indeed obey My voice and keep my covenant says the Lord ; , then you shall be My own possession among all the peoples. and you shall be to Me Kingdom of priests and a holy nation' Ex. 19: 5-6 ; . God promised to this people, Israel, that He would bless them with the covenant land forever, and would ever be `an enemy to their enemies, an adversary to their adversaries' Ex. 23: 22 ; . He further promised to set them high above the nations, with blessings and prosperity beyond their fondest hopes Deut. 28: 1-14 ; . So, one may ask: do these covenants remain unfulfilled? Or perhaps more accurately, are they just now in the process of being fulfilled - if we could grasp the entirety of His Word? Our God will move heaven and earth to fulfill every covenant promise, and just here is the scriptural foundation for understanding the unfolding of prophecy today. He is moving heaven and earth. Every promise of His Word will stand true forever. The restoration of Israel is basis enough for the understanding of our day. His people, His covenant, His Land will prove to be the vehicle for the consummation of the age, and the return of our Lord. Nonpharmacological stimuli in the drug self-administration paradigm to test their effectiveness in inducing reinstatement of drug seeking in animals Wikler and Pescor 1967; See 2002; Shaham et al. 2003 ; . In a more recent example, a recognition that protracted drug use in humans produces hallmark behavioral changes, such as continued use in the face of negative outcomes, persistent drug seeking during periods of drug absence, and increased motivation to obtain drug, has triggered methodological refinements in the animal model to assess the emergence of similar outcomes in rats Deroche-Gamonet et al. 2004; Vanderschuren and Everitt 2004 ; . While research on drug addiction in humans has influenced the design of experiments using animal models, investigations of the behavioral and neurobiological substrates of drug reinforcement in animals have also been instrumental in shaping our theories about drug dependence in humans. Here we review the utility of the drug selfadministration paradigm for extending our understanding of nicotine reinforcement. Recent data demonstrating an interaction between nicotine and nonpharmacological stimuli will be presented to illustrate the novel hypothesis that nicotine reinforcement derives from at least two sources: 1 ; the primary reinforcing effect of nicotine, an action that can sustain moderate levels of self-administration, can establish concurrent stimuli as conditioned reinforcers, and requires response-dependent drug administration, and 2 ; the effectiveness of nicotine in enhancing operant responding for reinforcing nonnicotine stimuli, an action that does not require a contingent relationship between drug administration and the reinforced operant see Table 1; Donny et al. 2003 ; . Parallel theories on the behavioral actions of psychostimulant drugs, such as cocaine, amphetamine, and pipradrol, will also be described. In addition, the capacity of nicotine to enhance reinforced behavior will be considered within the context of the neurobiological actions of nicotine, and the implications of this effect for smoking, smoking cessation, and the comorbid abuse of other addictive substances will be discussed.

Q: We just moved to Colorado and have been swamped by estate planning solicitations. We went to one presentation and got the scare of our lives. If we had only known how expensive and complicated it is to die in Colorado, we would never have relocated. A: It's not expensive. If your wills were good in your home state, they are valid in Colorado, along with Durable Powers of Attorney DPOA ; , although DPOAs are more likely to need changes just because of your move. In Colorado for a married couple with million or less of taxable worth, all that is needed is a standard will, durable powers of attorney, possibly a living will, and titling everything either in joint tenancy or having each other named as beneficiary or payable on death. All of the basic documents will probably cost less than 0 for each spouse to set up. For both federal and Colorado estates, there is no tax until million of taxable value has been accumulated. That figure is going up to .5 million in 2009. There is no tax in 2010 on any amount. In 2011, the exemption drops back to million. Thus, for a couple currently with no tax exposure, just doing wills would be a rational choice for the time being. If tax planning is needed for defensive planning, a tax will versus a tax living trust is a viable alternative in Colorado, costing anywhere from one-half to one-fifth the amount usually paid for a living trust. I might suggest redoing the Durable Powers of Attorney even though your out-of-state powers should work in Colorado. Often it is easier for the agent to use the wording and the format that is familiar in Colorado. I also prefer to sign four original DPOAs in case the principal becomes incapacitated and can't sign additional DPOAs. The cost is usually under 0 for each set of four Powers. Remember, durable powers of attorney are still needed even with living trusts in place. I might also suggest that you replace any out-of-state living wills the "shut off the machines" document ; since the Colorado form is free at any hospital and in my opinion has less of a chance of being rejected. Joint tenancy with right of survivorship and having each of you as the other's payable on death rounds and buy sertraline.

Treatment of the elderly suffering from psychosis and dementia. J Clin Psychiatry. 1996; 57 Suppl 9 ; : 5356. [QUESTION 238]The patient described in Question 237 would likely benefit most from treatment with an antipsychotic medication. Antipsychotic management of delusions in the context of dementia requires careful selection of medication to avoid worsening the patient's condition through adverse effects. Medications with anticholinergic side effects such as thioridazine, olanzapine, chlorpromazine, and clozapine must be used with caution, particularly in the presence of prostatic hyperplasia. In this case scenario, the addition of risperidone may be of benefit. Neither nortriptyline nor lithium is considered to have antipsychotic activity and thus both should be avoided. Patients with dementia who develop psychosis have a greater incidence of extrapyramidal side effects and tend to experience a more rapid progression of their dementia course. Although risperidone may produce some extrapyramidal effects, it appears to do so less frequently than other high-potency antipsychotic medications such as haloperidol. Therefore, risperidone may often be used safely in the older patient with psychosis and is likely to have a lower incidence of drug-induced parkinsonism, akathisia, and dystonias. Risperidone is often effective for psychosis in the context of dementia at dosages of 0.5 to 2.0 mg d. Additionally, in the setting of prominent idiopathic Parkinson's disease with psychosis, clozapine has also been reported to be effective. The magnitude of response, determined by the change in both primary efficacy measures total BPRS and CGI scores ; , was significantly in favor of clozapine irrespective of the population under evaluation. Similarly, response was significantly greater in the clozapine group for the majority of secondary efficacy measures, with the exception of the Psychotic Depression Scale where significant differences were found for the per-protocol population only ; and the Calgary Depression Scale. The superiority of clozapine in improving Positive and Negative Syndrome Scale total and subscores and CGI scores confirms the preliminary results of an open comparison of clozapine and risperidone in 86 patients with treatment-resistant schizophrenia for a mean treatment duration of 12 weeks 16 ; . Although the previous trial was small in size and of open design, the Positive and Negative Syndrome Scale total and positive subscores, general psychopathology subscores, and CGI score showed significantly greater improvement with clozapine than risperidone. Although the Positive and Negative Syndrome Scale and CGI efficacy data from both this present study and that of Flynn et al. 16 ; contrast with data from an earlier comparative 8-week study 15 ; , this latter study has received strong criticism for its design. First, because of its small sample size N 86 ; , it lacked the power to show a statistical difference between the two drugs. Furthermore, the target dose chosen for clozapine in the titration period 300 mg ; was too low, and plasma levels were lower than those found to be optimal in previous studies 2729 ; . The use of a subtherapeutic dose of clozapine by Bondolfi et al. 15 ; is likely to explain why the Positive and Negative Syndrome Scale score changes reported in their study for clozapine were markedly lower than those reported in this present study 23.2 versus 37.5, respectively ; , while risperidone-treated patients had similar Positive and Negative Syndrome Scale score changes 27.4 versus 29.9, respectively ; . Finally, the authors acknowledged that the 8week duration of treatment may not have been sufficient to achieve optimal response. During the study, there was an increase in antipsychotic dosage for risperidone while the clozapine dosage reAm J Psychiatry 158: 8, August 2001.
Flurbiprofen was an effective UGT2B7 inhibitor Bauman et al., 2005 ; , and the recombinant human UGTs, 1A1, 1A3, 1A4, and 2B15, have all been shown to catalyze racemic flurbiprofen glucuronidation Kuehl et al., 2005 ; . However, no enantioselective assay for flurbiprofen glucuronidation has been conducted as of yet, and the main UGT isozymes responsible for the formation of R ; - and S ; -flurbiprofen glucuronide remain to be determined. The novel information presented in the current study includes the identification of the predominant UGT isozymes involved in flurbiprofen glucuronidation in the human liver, and the determination of whether the UGT isozymes involved in the glucuronidation of the R ; - and S ; -forms differ. A simple comparison of the glucuronidation activity among UGT isozymes is not sufficient to elucidate the main UGTs involved in the liver since the UGT content in each recombinant UGT isozyme could not be determined and the relative abundance of UGTs in the human liver has not been determined. In addition, because little data on the specific inhibitors of the respective UGT isozyme are available, identification of the main UGT isozymes involved in the glucuronidation of drugs is more difficult than that in cytochrome P450-mediated metabolism. Thus, in order to determine the responsible UGT isozyme, correlation studies as well as inhibition studies should be conducted. The glucuronidation of -estradiol at the 3-OH position and propofol 7.

Van Os, Dept. of Psychiat. and Neuropsychol., Maastricht University, Europ. Grad. School of Neuroscience, PO Box 616 DRT 10 ; , 6200 MD Maastricht, Netherlands] - COMPR. PSYCHIATRY 2003 44 6 ; - summ in ENGL The origins of cerebral abnormalities in psychotic patients remain unknown. Dermatoglyphics are suitable markers of prenatal injury due to their fetal ontogenesis and their susceptibility to some of the factors that also affect cerebral development. In a previous study, positive associations between brain volumetric measures and a dermatoglyphic marker, the ab-ridge count, were reported. The present study is an attempt to replicate that finding in an independent sample. Magnetic resonance imaging MRI ; scans and dermatoglyphic measures were available for 29 schizophrenia patients Research Diagnostic Criteria [RDC] criteria ; and 26 unrelated healthy controls. The images were processed using an automated procedure, yielding volumes of total grey matter, white matter, cerebrospinal fluid CSF ; , and total brain volume. The ab-ridge count was not positively associated with brain volumes in either patients or controls. The present findings do not support the hypothesis that the changes in brain volume seen in patients with schizophrenia are of prenatal origin. 2003 Elsevier Inc. All rights reserved. 522. Relationship between levels of insulin or triglycerides and serum concentrations of the atypical antipsychotics clozapine and olanzapine in patients on treatment with therapeutic doses - Melkersson K.I. and Dahl M.-L. [K.I. Melkersson, Department of Molecular Medicine, Sollentuna Psychiatric Polyclinic, Karolinska Institute, Stockholm, Sweden] - PSYCHOPHARMACOLOGY 2003 170 2 ; - summ in ENGL Rationale: Recent results suggest that treatment with the atypical antipsychotics clozapine and olanzapine is associated with increased insulin and lipid levels. Objective: The aim of the present study was to investigate potential relationships between insulin or other hormones related to glucose-insulin homeostasis or lipids and steady-state serum concentrations of clozapine or olanzapine in patients on therapeutic doses. Methods: Thirty-four patients, diagnosed with schizophrenia or related psychoses according to the DSM-IV criteria and treated with clozapine n 18 ; or olanzapine n 16 ; , were studied. Median treatment time with the antipsychotics was 5.3 years range 0.5-16.3 years ; . Fasting blood samples for insulin, C-peptide, insulin-like growth factor I, insulinlike growth factor binding protein-1, leptin, glucose and lipids were analyzed and investigated in relation to the patients' drug serum concentrations. Results: Hyperinsulinemia was found in 30-60% of the patients, hyperglycemia in 10-30%, hyperlipidemia in 4060% and hyperleptinemia in 10-20%. Moreover, levels of insulin, C-peptide and triglycerides correlated positively to the clozapine serum concentration and to the ratio of olanzapine to N-desmethylolanzapine concentrations. In contrast, levels of C-peptide, leptin and blood glucose were inversely correlated to the serum concentration of the metabolite N-desmethylolanzapine. Conclusions: Metabolic abnormalities i.e. hyperinsulinemia, hyperlipidemia and hyperleptinemia ; and insulin resistance were associated with both clozapine and olanzapine treatments. Levels of insulin and triglycerides increased by increasing clozapine serum concentration and by increasing ratio of olanzapine to N-desmethylolanzapine; the last due to the metabolite N-desmethylolanzapine probably having an inverse effect to the main compound olanzapine. Thus, the metabolic abnormalities induced by these two drugs are clozapineconcentration dependent in clozapine-treated patients, and ratio of olanzapine to N-desmethylolanzapine- concentration dependent in olanzapine-treated patients.
