    The present study aimed to elucidate the effectiveness of clozapine treatment in reducing the disabling period of chronically ill schizophrenic patients by investigating their rehospitalization status. Of 232 schizophrenic patients with a history of clozapine use who were recruited from the clinic at Seoul National University Hospital, 117 were selected who had been followed up for more than 1 year with respect to rehospitalization. To obtain information about the period before the clozapine change, a chart review of these 117 patients was conducted. The number and length of hospitalizations of the patients significantly decreased after clozapine treatment compared to the same period before clozapine treatment. The hospital days per year of the patients were also decreased significantly after clozapine introduction. By analysing 38 patients who were followed up for more than 5 years, it was suggested that the decrease in the number and length of hospitalizations was substantially sustained for up to 5 years after clozapine treatment. This study showed that the number and length of hospitalizations are significantly decreased by long-term clozapine treatment and that this effect can positively affect the social outcome of schizophrenic patients.

    Cyproheptadine is a cheap, widely available anti-allergy drug with a broad receptor binding profile which resembles that of clozapine. In rats discriminating clozapine from vehicle cyproheptadine mimicked clozapine very closely. Acutely it induced full generalization in the absence of response suppression, as observed with clozapine. Chronic administration of clozapine and cyproheptadine induced tolerance and cross-tolerance respectively to the clozapine stimulus. This was characterized by circa 3.5-fold parallel shifts to the right in the clozapine generalization curves. Such tolerance and cross-tolerance was spontaneously reversible, suggesting that it was pharmacodynamic, and that clozapine and cyproheptadine induce similar neuroadaptations when administered chronically. Administration of chlordiazepoxide at a very high dose induced no cross-tolerance to the clozapine stimulus showing the pharmacological specificity of tolerance. The clozapine stimulus is a compound cue involving actions at various receptors, and various clozapine-like antipsychotic (APD) drugs generalize fully to it. These data demonstrate that in vivo cyproheptadine resembles clozapine both acutely and chronically. Our findings, in conjunction with other actions of cyproheptadine -- induction of weight gain, alleviation of clozapine withdrawal, anxiolytic actions, alleviation of 'typical' APD-induced motoric side effects, and some preliminary clinical findings -- suggest that further study of cyproheptadine in conjunction with a 'typical' APD for the possible treatment of schizophrenia is merited at both pre-clinical and clinical levels.

    The aim of this study is to evaluate the safety and effectiveness of rapid clozapine titration in patients with schizophrenia in hospital settings. We conducted a retrospective two-center cohort study to compare the safety and effectiveness of clozapine with different titration rates in treatment-refractory patients with schizophrenia. In the first center, clozapine was started at 25-50 mg followed by 50-100 mg as needed every 6 h on day 1, followed by increases of 50-100 mg/day. In the second center, titration was slower; clozapine initiated with 12.5-50 mg on day 1 followed by increases of 25-50 mg/day. The number of days between starting of clozapine until discharge was shorter in the rapid titration group (22.4 ± 8.72 vs 27.0 ± 10.5, p = 0.1). Number of days of total hospital stay were significantly shorter in the rapid titration group (29.6 ± 10.6 vs 41.2 ± 14.8, p = 0.002). Hypotension was more common in the rapid titration group and one patient had suspected myocarditis. Rapid clozapine titration appeared safe and effective. The length of stay following initiation of clozapine was shorter in the rapid-titration group, although this was not statistically significant. However starting clozapine earlier together with rapid titration has significantly shortened the length of hospital stay in patients with treatment refractory schizophrenia.

  5. Is clonidine useful for treatment of clozapine-induced sialorrhea?

    Clozapine has shown superior efficacy in treatment of refractory schizophrenia, but its use is limited by emergent side-effects. Among other adverse effects, sialorrhea is a troublesome side-effect, its stigmatizing nature results in poor treatment compliance. Several hypotheses have been put forward in the etiology of clozapine-induced sialorrhea. 2 adrenergic antagonism is hypothesized to be involved in its pathophysiology, based on the response to clonidine and lofexidine. Oral clonidine (50 to 100 g/day) was tried on 12 stable outpatients of schizophrenia maintained on clozapine. Wet area over the pillow as reported by the patients was recorded at baseline and at 4 weeks of treatment along with the subjective response after the treatment. Most of the patients reported a decrease in sialorrhea without any adverse events. We describe encouraging results in an open case series of oral clonidine for clozapine-induced sialorrhea.

    Background Although clozapine has been shown to be the treatment of choice in people with schizophrenia that are resistant to treatment, one third to two thirds of people still have persistent positive symptoms despite clozapine monotherapy of adequate dosage and duration. The need to provide effective therapeutic interventions to patients who do not have an optimal response to clozapine is the most common reason for simultaneously prescribing a second antipsychotic drug in combination with clozapine. Objectives To determine the efficacy and tolerability of various clozapine combination strategies with antipsychotics in people with treatment resistant schizophrenia. Search methods We searched the Cochrane Schizophrenia Group Trials Register (March 2008) and MEDLINE (up to November 2008). We checked reference lists of all identified randomised controlled trials and requested pharmaceutical companies marketing investigational products to provide relevant published and unpublished data. Selection criteria We included only randomised controlled trials recruiting people of both sexes, aged 18 years or more, with a diagnosis of treatment-resistant schizophrenia (or related disorders) and comparing clozapine plus another antipsychotic drug with clozapine plus a different antipsychotic drug. Data collection and analysis Two review authors independently extracted data and resolved disagreement by discussion with third member of the team. When insufficient data were provided, we contacted the study authors. Main results Three small (range of number of participants 28 to 60) randomised controlled trials were included in the review. Even though results from individual studies did not find that one combination strategy is better than the others, the methodological quality of included studies was too low to allow authors to use the collected data to answer the research question correctly. Authors’ conclusions In this review we considered the risk of bias too high because of

    Antipsychotic drugs are the best means available for symptomatically treating individuals suffering from schizophrenia; however, there is a significant variability in clinical response to these psychotropic medications. Previous findings connect oxytocin (OXT) with schizophrenia and antipsychotic action. Therefore, we evaluated if OXT and OXT receptor (OXTR) genes might play a role in the symptom severity and clozapine treatment response in schizophrenia subjects. The rs2740204 variant in the OXT gene was significantly associated with treatment response (after 1000 permutations p=0.042) and nominally associated with negative symptoms in our sample. Furthermore, variants in the OXTR were nominally associated with severity of overall symptoms accessed using the Brief Psychiatric Rating Scale (rs237885, rs237887) as well as on the improvement of the positive symptoms (rs11706648, rs4686301, rs237899). Additional association studies in independent samples will be able evaluate whether OXT and OXTR genes are truly playing a role in the clozapine treatment outcome.

    Objectives Despite clozapine’s superior clinical efficacy in Treatment Resistant Schizophrenia (TRS), its adverse effects, need for periodic leukocyte monitoring, cost and variable clinical outcomes make the therapeutic decision making process difficult and mandate a clinical need to predict its treatment response. Hence, we investigated various clinical variables associated with treatment responses and adverse events of clozapine in TRS. Experimental Design We assessed socio-demographic and clinical profiles, premorbid adjustment, traumatic life events, cognition, disability, psychopathology and serum clozapine levels of 101 patients with TRS on stable dose of clozapine using the following instruments: Brief Psychiatric Rating Scale, Abnormal Involuntary Movements Scale, Addenbrooke’s Cognitive Examination—Revised, WHO Disability Assessment Scale-II, Childhood and Recent Traumatic Events Scale, and Premorbid Assessment Scale. We defined clozapine response a priori, adopted a case-control design framework and employed appropriate multivariate analyses. Principal Observations Past history of catatonia (p = 0.005), smoking more than one pack/day (p = 0.008), hyper-somnolence (p = 0.03) and cognitive dysfunction (p = 0.007) were associated with non-response to clozapine. Outcome definitions of non-response to clozapine influenced its association with clinical predictors. Conclusions Clinical variables are useful to predict response to clozapine. Smoking can be a potentially modifiable risk factor. Future longitudinal studies, investigating clinical and pharmacogenetic variables together, are desired.

    Objectives Clozapine is an atypical antipsychotic primarily prescribed for treatment-resistant schizophrenia. We tested the specific effect of clozapine versus other drug treatments on whole-blood gene expression in a sample of patients with psychosis from the UK. Methods A total of 186 baseline whole-blood samples from individuals receiving treatment for established psychosis were analysed for gene expression on Illumina HumanHT-12.v4 BeadChips. After standard quality-control procedures, 152 samples remained, including 55 from individuals receiving clozapine. In a within-case study design, weighted gene correlation network analysis was used to identify modules of coexpressed genes. The influence of mood stabilizers, lithium carbonate/lithium citrate and sodium valproate was studied to identify their possible roles as confounders. Results Individuals receiving clozapine as their only antipsychotic (clozapine monotherapy) had a nominal association with one gene-expression module, whereas no significant change in gene expression was found for other drugs. Conclusion Overall, this study does not provide evidence that clozapine treatment induces medium to large different gene-expression patterns in human whole blood versus other antipsychotic treatments. This does not rule out the possibility of smaller effects as observed for other common antipsychotic treatments. PMID:27315048

    Despite evidence that clozapine may be neuroprotective, there are few longitudinal magnetic resonance imaging (MRI) studies that have specifically explored an association between commencement of clozapine treatment for schizophrenia and changes in regional brain volume or cortical thickness. A total of 33 patients with treatment-resistant schizophrenia and 31 healthy controls matched for age and gender underwent structural MRI brain scans at baseline and 6-9 months after commencing clozapine. MRI images were analyzed using SIENA (Structural Image Evaluation, using Normalization, of Atrophy) and FreeSurfer to investigate changes over time in brain volume and cortical thickness respectively. Significantly greater reductions in volume were detected in the right and left medial prefrontal cortex and in the periventricular area in the patient group regardless of treatment response. Widespread further cortical thinning was observed in patients compared with healthy controls. The majority of patients improved symptomatically and functionally over the study period, and patients who improved were more likely to have less cortical thinning of the left medial frontal cortex and the right middle temporal cortex. These findings demonstrate on-going reductions in brain volume and progressive cortical thinning in patients with schizophrenia who are switched to clozapine treatment. It is possible that this gray matter loss reflects a progressive disease process irrespective of medication use or that it is contributed to by switching to clozapine treatment. The clinical improvement of most patients indicates that antipsychotic-related gray matter volume loss may not necessarily be harmful or reflect neurotoxicity.

    Objective: Clozapine is a second-generation antipsychotic used for treatment-resistant schizophrenia. Despite its effectiveness, clozapine is largely underused due to serious side effects such as leukopenia or neutropenia. We aimed to review whether to continue, discontinue or rechallenge clozapine treatment after such haematological side effects. Methods: We reviewed and summarized the literature on the use of clozapine, how to deal with its side effects, and suitable options in case of any haematological problems. Then, we described several cases successfully treated with clozapine and lithium after development of neutropenia or leukopenia Results: We present three patients with treatment-resistant schizophrenia. While they had demonstrated poor response to multiple antipsychotic trials, clozapine was started. Clozapine induced neutropenia; or leukopenia developed in some cases that was successfully reversed after lithium onset. Increased serious side effects related with coprescription of lithium and clozapine were not observed. Conclusion: Lithium increases neutrophil and total white blood cell count as a side effect that may be useful in patients who develop neutropenia or leukopenia while being treated with clozapine.

    Three ethical constructs of distributive justice--utilitarianism, Marxism, and the theories of John Rawls--are applied to selection of patients for treatment with clozapine. Elements of an ethical selection process include a means of monitoring the clinical effectiveness of the drug so that it is not wasted and procedures for ensuring that patients' rights to advocacy and due process are met. The authors suggest that a disproportionate number of patients with tardive dyskinesia may receive clozapine because clinicians and hospitals risk litigation if these patients continue to receive standard neuroleptics and experience worsening side effects.

    This preliminary prospective study evaluated cardiac status in 15 treatment-resistant schizophrenia patients (aged 18-55 years) without evidence of cardiovascular disease. Patients underwent clinical assessment, blood tests, ECG, and echocardiography before and during clozapine treatment for 4 weeks as doses increased from 25 to 100 mg/day. Serum concentrations of high-sensitivity C-reactive protein, troponin-I, brain natriuretic peptide, and clozapine+norclozapine were assayed at week 3; ECG and echocardiography were repeated at week 4. At moderate serum drug concentrations (124 ng/ml), the heart rate increased by 10% and high-sensitivity C-reactive protein levels were slightly elevated, but troponin-I and brain natriuretic peptide levels were not elevated. Echocardiographic indices indicated declining left ventricular (LV) diastolic and systolic function in 60-80% of participants, with an increase in systolic pulmonary artery pressure, A-wave velocity, and LV myocardial performance index by 16-24% in 60-80% of participants and a decrease in the E/A ratio by 29% in 73% of participants - all uncorrelated with drug concentrations. Early treatment with moderate doses of clozapine was associated with subclinical but substantial decreases in LV functioning in surprisingly high proportions of participants. Studies with more participants, higher drug doses, and long-term follow-up are needed to confirm and determine the course of the observed abnormalities and to evaluate their relationship with rare clinical cardiotoxicity associated with clozapine.

    Clozapine is known to be effective in treating schizophrenia patients with comorbid alcohol use disorders (AUD). However, few prospective studies have examined the effect of clozapine on community survival of the patient, which is one of the most important indicators of success for patients with schizophrenia. In this prospective, naturalistic, observational, community-survival-analysis study, we compared the effect of clozapine and risperidone on two-year psychiatric hospitalization rate and time to hospitalization in the treatment of patients with schizophrenia and comorbid AUD. We found that the clozapine treated patients were readmitted to hospital significantly later (mean survival=526.5 days, n=25 patients) than the risperidone treated patients (mean survival=420.4 days, n=36 patients). The survival curve for the clozapine-treated patients was significantly different from that of the risperidone treated patients (log-rank test, df=1, p=.045). At the end of the two-year study period, 75% of the risperidone treated patients had been admitted to the hospital, compared to only 48% of the clozapine treated patients. These findings suggest that clozapine should be considered for the treatment of schizophrenia patients with comorbid AUD. However, due to the limitations of this study, further studies will be required to confirm these findings. PMID:18262321

    Clozapine has been in use since 1975. It was withdrawn due to its toxic effects on granulocytes. It was reintroduced due to its positive effect on schizophrenia in patients who did not respond to two antipsychotic drugs. These patients suffer from a chronic debilitating disease, with numerous and sometimes chronic hospitalizations. Clozapine also has antiaggression and antisuicide effects, as well as specific effects on the negative symptoms of schizophrenia. There are severe side effects that may appear. These include suppression of granulocytes, cardiotoxic effect on the myocard, as well as cardiac conduction defects. It may also cause weight gain and early appearance of diabetis mellitus. All these side effects require strict and intensive monitoring. Clozapine blood Levels are needed for ascertaining the required dose. This article describes several reasons for the low level of use of clozapine in Israel. These include its side effect profile, tendency to use new medications, the demanding monitoring for side effects and the need for long term treatment to achieve clinical improvement.

    This 18-week, randomized, flexible-dose, double-blind, double-dummy trial evaluated ziprasidone as an alternative to clozapine in treatment-refractory schizophrenia patients. Patients had a DSM-IV diagnosis of schizophrenia, a history of resistance and/or intolerance to at least three acute cycles with different antipsychotics given at therapeutic doses, PANSS score >or=80, and CGI-S score >or=4. Patients were randomized to ziprasidone (80-160 mg/day, n=73) or clozapine (250-600 mg/day, n=74). On the primary ITT-LOCF analysis, baseline-to-endpoint decreases in PANSS total scores were similar in the ziprasidone (-25.0+/-22.0, 95% CI -30.2 to -19.8) and clozapine (-24.5+/-22.5, 95% CI -29.7 to -19.2) groups. A progressive and significant reduction from baseline in PANSS total score was observed from day 11 in both study arms. There were also significant improvements on PANSS subscales, CGI-S, CG-I, CDSS, and GAF, without between-drug differences. The two treatment groups had similar rates of early discontinuations due to AEs. AEs were mostly of similar mild-moderate severity in the two groups. There were also no detrimental effects on prolactin, renal and liver function, hematology, and cardiovascular parameters. However, ziprasidone but not clozapine showed a significant reduction of SAS and AIMS scores. Moreover, when compared with clozapine, ziprasidone also had a more favorable metabolic profile, with significant endpoint differences in weight, fasting glucose, total cholesterol, LDL cholesterol, and triglycerides. In conclusion, this trial indicates that both ziprasidone and clozapine, having comparable efficacy coupled with satisfactory general safety and tolerability, may be regarded as valuable options for the short-term treatment of difficult-to-treat schizophrenia patients with a history of multiple resistance and/or intolerance to antipsychotics. The more favorable metabolic profile of ziprasidone may represent an added value that could guide clinicians

  2. Comparison of Classical and Clozapine Treatment on Schizophrenia Using Positive and Negative Syndrome Scale of Schizophrenia (PANSS) and SPECT Imaging

    2005-01-01

    Many neuroimaging studies of schizophrenia have shown abnormalities in the frontal cortex, limbic system, basal ganglia, temporal and parietal lobes. These findings are not specific or consistent enough to build up a coherent theory of the origin of the brain abnormality in schizophrenia. This paper describes a state-of-the-art approach of SPECT to correlate neuropsychological evaluation. PANSS scores and different brain focal abnormalities of two groups of patients receiving Clozapine and classical antipsychotic treatments were observed. A total of 20 drug-free patients, actively psychotic schizophrenic, were selected according to the DSM-IV criteria. Pre-Post-treatment was designed using PANSS and 99mTc- ECD-SPECT to assess regional Cerebral Blood Flow (rCBF). The results showed that after treatment, differences in PANSS scores were significant in both groups, with superior scores resulting from the Clozapine therapy. Results were supported by SPECT, which showed a greater improvement in the Clozapine group. Both positive and negative symptoms were improved with Clozapine as well. Before treatment, hypofrontality was the most common (85%) finding, whereas after treatment hypofrontality was mostly cleared. However, in some areas like temporal and caudate, hyperfrontality was induced. Negative symptoms showed linkage to hypofrontality in both groups before and after treatment, and both positive and negative symptoms were improved more with Clozapine therapy than with classical treatment.

    Clozapine has been consistently shown to be superior to other antipsychotics in the treatment of psychosis. However, clozapine usage has been limited due to required routine blood monitoring and the potential for life threatening side effects. We report a case of a 66-year-old female patient, who developed clozapine-induced agranulocytosis after 10 weeks of clozapine treatment and was subsequently successfully treated with a combination of loxapine and cyproheptadine. The combination is thought to mimic the pharmacological profile of clozapine, rendering it as a possible alternative to traditional clozapine treatment.

    Clozapine has been consistently shown to be superior to other antipsychotics in the treatment of psychosis. However, clozapine usage has been limited due to required routine blood monitoring and the potential for life threatening side effects. We report a case of a 66-year-old female patient, who developed clozapine-induced agranulocytosis after 10 weeks of clozapine treatment and was subsequently successfully treated with a combination of loxapine and cyproheptadine. The combination is thought to mimic the pharmacological profile of clozapine, rendering it as a possible alternative to traditional clozapine treatment. PMID:27433365

    This multisite study was conducted to compare the efficacy and tolerability of combination treatment with clozapine plus aripiprazole versus combination treatment with clozapine plus haloperidol in patients with schizophrenia who do not have an optimal response to clozapine. Patients continued to take clozapine and were randomly assigned to receive daily augmentation with aripiprazole or haloperidol. Physicians prescribed the allocated treatments according to usual clinical care. Withdrawal from allocated treatment within 3 months was the primary outcome. Secondary outcomes included severity of symptoms on the Brief Psychiatric Rating Scale and antipsychotic subjective tolerability on the Liverpool University Neuroleptic Side Effect Rating Scale. A total of 106 patients with schizophrenia were randomly assigned to treatment. After 3 months, we found no difference in the proportion of patients who discontinued treatment between the aripiprazole and haloperidol groups (13.2% vs 15.1%, P = 0.780). The 3-month change of the Brief Psychiatric Rating Scale total score was similar in the aripiprazole and haloperidol groups (-5.9 vs -4.4 points, P = 0.523), whereas the 3-month decrease of the Liverpool University Neuroleptic Side Effect Rating Scale total score was significantly higher in the aripiprazole group than in the haloperidol group (-7.4 vs -2.0 points, P = 0.006). These results suggest that augmentation of clozapine with aripiprazole offers no benefit with regard to treatment withdrawal and overall symptoms in schizophrenia compared with augmentation with haloperidol. However, an advantage in the perception of adverse effects with aripiprazole treatment may be meaningful for patients.

    Clozapine is a gold standard medication and drug of choice in refractory schizophrenia. Among many of its fatal side effects, delirium is less reported and inconsistently recognized by clinicians. We here present a case of delirium which emerged during retreatment with clozapine in a patient of paranoid schizophrenia. A patient diagnosed with paranoid schizophrenia, was restarted on clozapine after he left medications and became symptomatic. He was delirious on 22nd day after clozapine was restarted. Clozapine was stopped and the patient was managed with standard treatment for delirium. After one week interval, clozapine was restarted. Delirium was not noted till 6 weeks of his hospital stay. Clozapine induced central anticholinergic toxicity or clozapine induced seizure might cause delirium in index case. Limited literature exist delirium with clozapine. Clinicians must have high index of suspicion to detect delirium during clozapine therapy. More researches should focus to explore the association between delirium and clozapine. PMID:26792049

    Clozapine is the treatment of choice for treatment-resistant schizophrenia, but it is associated with a risk of neutropaenia and agranulocytosis. Clozapine use is regulated by mandatory blood monitoring in the UK, requiring cessation of treatment should the absolute neutrophil count (ANC) drop below specified values. Benign reductions in the ANC in non-white populations are common, and this can preclude a patient from receiving treatment with clozapine. A diagnosis of benign ethnic neutropaenia can reduce these treatment restrictions (UK specific), but the degree of neutropaenia can be significant enough to still prevent treatment. In this report, we show that response to granulocyte colony stimulating factor (G-CSF) may be quite variable and difficult to predict, but with careful monitoring it can be used to increase the ANC count and allow continued treatment with clozapine.

    Agranulocytosis as a side effect of clozapine has been reported to be associated with initial phases of treatment, i.e., first six months. Agranulocytosis with clozapine during the initial phases of treatment has been linked to genetic vulnerability in the form of variations in the human leukocyte-antigen haplotypes. However, there is limited literature on late onset agranulocytosis with clozapine and this has very rarely been linked to human leukocyte-antigen haplotypes vulnerability. In this report we review the existing data on late onset agranulocytosis with clozapine and describe the case of a young man, who developed agranulocytosis with clozapine after 35 months of treatment and was found to have genetic vulnerability in form of being positive for HLA DR4. This case highlights underlying autoimmune immune mechanism in clozapine-induced agranulocytosis and the need for frequent blood count monitoring on clozapine even after the initial 6 months of starting treatment especially in patients with genetic vulnerability to develop this condition.

    2009-01-01

    Introduction Given the limited range of effective drug treatments for patients with schizophrenia, increasing numbers of patients, often termed 'treatment-resistant' are prescribed clozapine. While the induction of neutropenia or agranulocytosis by clozapine is well appreciated, other rare potentially fatal adverse reactions may also occur including acute interstitial nephritis as reported in this case. Case presentation A 57-year-old Caucasian woman with treatment-resistant chronic schizophrenia developed acute renal failure following initiation of treatment with clozapine. The adverse reaction occurred after only four doses of the drug had been administered (titrated from 12.5 to 25 mg per day). After clozapine had been withdrawn, the patient's renal function returned to normal with no other changes to medication. The patient had been exposed to clozapine about 4 years previously when she had developed a similar reaction. Conclusion Renal reactions to clozapine are extremely rare but, if not recognized promptly, may prove fatal. Psychiatrists need to be aware of this possible complication when clozapine is initiated.

    Metabolic complications are commonly found in people treated with clozapine. Reviews on the management of this problem have generally drawn conclusions by grouping different types of studies involving patients treated with various different antipsychotics. We carried out a systematic review and meta-analysis of pharmacological and non-pharmacological treatments for clozapine-induced obesity or metabolic syndrome. Two researchers independently searched PubMed and Embase for randomised controlled trials (RCTs) of treatments for clozapine-induced obesity or metabolic syndrome. All other types of studies were excluded. We only included RCTs where more than 50% of participants were taking clozapine. We identified 15 RCTs. Effective pharmacological treatments for clozapine-induced obesity and metabolic syndrome include metformin, aripiprazole, and Orlistat (in men only). Meta-analysis of three studies showed a robust effect of metformin in reducing body mass index and waist circumference but no effects on blood glucose, triglyceride levels, or HDL levels. In addition, there is limited evidence for combined calorie restriction and exercise as a non-pharmacological alternative for the treatment of clozapine-induced obesity, but only in an in-patient setting. Rosiglitazone, topiramate, sibutramine, phenylpropanolamine, modafinil, and atomoxetine have not shown to be beneficial, despite reports of efficacy in other populations treated with different antipsychotics. We conclude that randomised-controlled trial data support the use of metformin, aripiprazole, and Orlistat (in men only) for treating clozapine-induced obesity. Calorie restriction in combination with an exercise programme may be effective as a non-pharmacological alternative. Findings from trials in different populations should not be extrapolated to people being treated with clozapine. PMID:27496573

  14. Risks and Benefits of Rapid Clozapine Titration.

    Clozapine is often considered the gold standard for the treatment of schizophrenia. Clinical guidelines suggest a gradual titration over 2 weeks to reduce the risks of adverse events such as seizures, hypotension, agranulocytosis, and myocarditis. The slow titration often delays time to therapeutic response. This raises the question of whether, in some patients, it may be safe to use a more rapid clozapine titration. The following case illustrates the potential risks associated with the use of multiple antipsychotics and rapid clozapine titration. We present the case of a young man with schizophrenia who developed life threatening neuroleptic malignant syndrome (NMS) during rapid clozapine titration and treatment with multiple antipsychotics. We were unable to find another case in the literature of NMS associated with rapid clozapine titration. This case is meant to urge clinicians to carefully evaluate the risks and benefits of rapid clozapine titration, and to encourage researchers to further evaluate the safety of rapid clozapine titration. Rapid clozapine titration has implications for decreasing health care costs associated with prolonged hospitalizations, and decreasing the emotional suffering associated with uncontrolled symptoms of psychosis. Clozapine is considered the most effective antipsychotic available thus efforts should focus on developing strategies that would allow for safest and most efficient use of clozapine to encourage its utilization for treatment resistance schizophrenia.

    Clozapine is an atypical and novel antipsychotic medication useful for patients with schizophrenia who are refractory to treatment. Its use is often associated with troublesome side effects like sialorrhea, sedation, weight gain, enuresis, dizziness, besides life threatening side effects like agranulocytosis. Drug treatments used for Clozapine induced sialorrhea (CIS) like anticholinergic drugs and alpha 2 receptor antagonists have their own added side effects. A case of CIS responding to low dose of Amisulpride is reported.

    Background Clozapine causes significant metabolic disturbances including obesity and type 2 diabetes. Recent evidence that reduced glucagon-like-peptide-1 (GLP-1) may contribute to aetiology of clozapine-associated metabolic dysregulation suggests a potential therapeutic role for GLP-1 agonists. Method This open-label, pilot randomised controlled trial evaluates the effect of exenatide in clozapine-treated obese adults who have schizophrenia, with or without poorly controlled diabetes. Sixty out-patients will be randomised to once weekly extended release exenatide or treatment as usual for 24 weeks. Aims To evaluate the feasibility of larger studies regarding methodology, acceptability, tolerability and estimate efficacy for glycaemic control or weight loss. Secondary outcomes are psychosis severity and metabolic parameters. Conclusions This is the first trial investigating GLP-1 agonists for glycaemic control and weight loss in clozapine-treated patients with either diabetes or obesity. Clozapine-associated obesity and diabetes with exenatide (CODEX) will provide proof-of-concept empirical evidence addressing whether this novel treatment is practical and worthy of further investigation.

    Background One third to two thirds of people with schizophrenia have persistent psychotic symptoms despite clozapine treatment. Under real-world circumstances, the need to provide effective therapeutic interventions to patients who do not have an optimal response to clozapine has been cited as the most common reason for simultaneously prescribing a second antipsychotic drug in combination treatment strategies. In a clinical area where the pressing need of providing therapeutic answers has progressively increased the occurrence of antipsychotic polypharmacy, despite the lack of robust evidence of its efficacy, we sought to implement a pre-planned protocol where two alternative therapeutic answers are systematically provided and evaluated within the context of a pragmatic, multicentre, independent randomised study. Methods/Design The principal clinical question to be answered by the present project is the relative efficacy and tolerability of combination treatment with clozapine plus aripiprazole compared with combination treatment with clozapine plus haloperidol in patients with an incomplete response to treatment with clozapine over an appropriate period of time. This project is a prospective, multicentre, randomized, parallel-group, superiority trial that follow patients over a period of 12 months. Withdrawal from allocated treatment within 3 months is the primary outcome. Discussion The implementation of the protocol presented here shows that it is possible to create a network of community psychiatric services that accept the idea of using their everyday clinical practice to produce randomised knowledge. The employed pragmatic attitude allowed to randomly allocate more than 100 individuals, which means that this study is the largest antipsychotic combination trial conducted so far in Western countries. We expect that the current project, by generating evidence on whether it is clinically useful to combine clozapine with aripiprazole rather than with haloperidol

    Clozapine remains the antipsychotic of choice for refractory schizophrenia despite its propensity for serious blood disorders. When neutropenia or agranulocytosis occur in people taking clozapine, cessation of treatment is mandated and relapse often results. Because such patients are usually unresponsive to other antipsychotics, many clinicians consider restarting clozapine, despite the risks involved. However, the risks of clozapine rechallenge vary according to the cause and nature of the blood dyscrasia. Neutropenia can arise because of factors unrelated or indirectly related to clozapine treatment. These include benign ethnic neutropenia, concomitant drug therapy, co-existing medical conditions and drug interactions. In such cases, clozapine may be restarted if non-clozapine causes of neutropenia are identified and eliminated, although concurrent treatment with lithium (to induce leukocytosis) is sometimes necessary. Close monitoring of the patient is essential because it is rarely possible to completely rule out the contribution of clozapine to the blood dyscrasia and because lithium does not protect against clozapine-related agranulocytosis. In cases of clozapine-induced neutropenia (as distinct from agranulocytosis, which may have a different pathology) rechallenge may also be considered and, again, lithium co-therapy may be required. Where clozapine is clearly the cause of agranulocytosis, rechallenge should not be considered or undertaken unless there are very exceptional circumstances (severe and prolonged relapse following clozapine discontinuation). In these cases, re-exposure to clozapine may rarely be attempted where there are facilities for very close and frequent monitoring. Granulocyte colony-stimulating factor is likely to be required as co-therapy, given the very high likelihood of recurrence. Uncertainty over the likely cause of blood dyscrasia in people taking clozapine, coupled with uncertainty over the mechanism by which clozapine causes both

    Clozapine is a major atypical antipsychotic drug used in treatment-resistant schizophrenia (Patel and Allin. Ther Adv Psychopharmacol 2011;1:25-29). It interferes with dopamine binding to D1, D2, D3, and D5 receptors but has high affinity to D4. It also has an anticholinergic effect and antagonizes α-adrenergic, histaminergic, and serotoninergic receptors (Oerther and Ahlenius. J Pharmacol Exp Ther 2000;292:731-736). Clozapine has proved effective in treating positive and negative symptoms in patients with refractory schizophrenia, thus accounting for its frequent use. Despite its effectiveness, this drug is not without its adverse effects. The most well known is agranulocytosis. There are, however, many others, such as myocarditis, aspiration pneumonia, ileus, fever, hyperglycemia, hyperlipidemia, hypertriglycemia, tachycardia, and weight gain, among others (Bruijnzeel et al. Asian J Psychiatr 2014;11:3-7). Fever induced by clozapine is a common phenomenon (Lowe et al. Ann Pharmacother 2007;41:1700-1704), which usually occurs in the first 4 weeks of treatment, and its prevalence oscillates from 0.5% and 55%, depending on the study (Jeong et al. Schizophr Res 2002;56:191-193; Young et al. Schizophr Bull 1998;24:381-390). The fever lasts for 2.5 days on average, and unless the treatment is discontinued, it generally abates between day 8 and 16 of treatment (Kohen et al. Ann Pharmacother 2009;43:143-146). There are several different theories about the physiopathological mechanism; it could be a variation of malignant neuroleptic syndrome, an infection secondary to neutropenia, and allergic reaction or the emergence of the immunomodulating effect of clozapine. Some case reports in the bibliography have shown that patients in treatment with clozapine can develop a mild leukocytosis, but the presence of other concurrent symptoms, which indicate infection, is not common (Tham and Dickson. J Clin Psychiatry 2002;63:880-884). The theory of an allergic reaction is

    Treatment of severe and refractory manic episodes in hospital settings can occasionally be very difficult. In particular, severely excited patients showing aggressive, hostile, impulsive behaviours frequently require physical restraint and seclusion, high doses of antipsychotics and benzodiazepines, and sometimes, electroconvulsive therapy. Hospital stay is generally prolonged and such patients cause great emotional distress for other patients in the ward and clinical staff involved in their care. Here we report on three patients with a diagnosis of bipolar disorder and one patient with a diagnosis of schizoaffective disorder bipolar subtype, all of whom were hospitalized for severe manic episodes with psychotic features. These patients were extremely difficult to manage in the ward as no response could be obtained in the first week of treatment despite high doses of antipsychotics and benzodiazepine administration. The introduction and rapid titration of clozapine proved remarkably effective and was well tolerated in the acute management of these patients. We observed that clozapine had a superior and fast mood stabilization effect with rapid titration and could be extremely helpful in the management of such patients. PMID:26301080

    Schizophrenia disease models are necessary to elucidate underlying changes and to establish new therapeutic strategies towards a stage where drug efficacy in schizophrenia (against all classes of symptoms) can be predicted. Here we summarise the evidence for a GABA dysfunction in schizophrenia and review the functional neuroanatomy of five pathways implicated in schizophrenia, namely the mesocortical, mesolimbic, ventral striopallidal, dorsal striopallidal and perforant pathways including the role of local GABA transmission and we describe the effect of clozapine on local neurotransmitter release. This review also evaluates psychotropic drug-induced, neurodevelopmental and environmental disease models including their compatibility with brain microdialysis. The validity of disease models including face, construct, etiological and predictive validity and how these models constitute theories about this illness is also addressed. A disease model based on the effect of the abrupt withdrawal of clozapine on GABA release is also described. The review concludes that while no single animal model is entirely successful in reproducing schizophreniform symptomatology, a disease model based on an ability to prevent and/or reverse the abrupt clozapine discontinuation-induced changes in GABA release in brain regions implicated in schizophrenia may be useful for hypothesis testing and for in vivo screening of novel ligands not limited to a single pharmacological class.

    Clinical studies have shown clozapine to be effective in the treatment of schizophrenia and associated with an extremely low incidence of extrapiramidal side effects. Diverse studies indicate that clozapine is an atypical neuroleptic with a preferential activity on the mesolimbic structures and a lower affinity for striatal D2 receptors than the classical antipsychotics. The purpose of this study was to assess the behavioral properties of clozapine, especially its effects on aggressive and motor behaviors. Individually housed male mice of the OF1 strain were exposed to anosmic "standard opponents" 30 minutes after the last drug administration. One category of animals received a single IP dose of the compound (0.2, 0.5, 1 or 1.5 mg/kg). Another category received daily doses (0.5, 1 or 1.5 mg/kg) for 21 days. Encounters were videotaped and behavior evaluated using an ethologically based analysis. Clozapine, in the acute treatment condition, produced a significant decrease in "attack" and "threat" behaviors without "immobility" being significantly increased. These results suggest a rather specific antiaggressive action of the compound with little motor impairment. In the chronic administration, no significant change in aggressive behavior was observed which may be attributed to the development of some degree of tolerance.

    Astrocytic markers glial fibrillary acidic protein (GFAP) and connexin 43 (CX43) are known to have altered expression in brains of subjects with psychiatric disorders including autism and major depression. The current study investigated whether GFAP and CX43 expressions are affected by several commonly used psychotropic medications (clozapine, fluoxetine, haloperidol, lithium, olanzapine, and valproic acid). Using SDS-PAGE and western blotting technique, we observed that CX43 protein expression in prefrontal cortex was significantly increased following chronic treatment with fluoxetine and clozapine, while it was significantly decreased by haloperidol and lithium. GFAP protein expression was significantly decreased following chronic treatment with clozapine and valproic acid. These results suggest that astroglial markers GFAP and CX43 could be potential targets for therapeutic intervention.

    Clozapine is the treatment of choice in refractory schizophrenia. Its more extensive use is limited by adverse effects and the need for regular blood monitoring. However, black patients are disadvantaged with respect to clozapine usage. Lower baseline Absolute Neutrophil Count compared with Whites leads to a greater frequency of blood testing, treatment interruptions and discontinuation. This may in part be explained by Benign Ethnic Neutropenia, but too few black patients are thus registered. The four cases described in this report underline some of the difficulties if this problem is under-recognized. Moreover, in our sample of 191 clozapine recipients in an inner London hospital, black patients account for approximately half, but only a small proportion, 8/95 (8.4%) are registered as having Benign Ethnic Neutropenia. None of the Benign Ethnic Neutropenia-registered patients discontinued treatment for haematological reasons. To optimize clozapine treatment and improve long-term outcomes, a significantly greater proportion of Black patients should be registered as having Benign Ethnic Neutropenia.

    This meta-analysis of randomized controlled trials (RCTs) examined the efficacy and safety of the combination of electroconvulsive therapy (ECT) and antipsychotic medication (except for clozapine) versus the same antipsychotic monotherapy for treatment-resistant schizophrenia (TRS). Two independent investigators extracted data for a random effects meta-analysis and pre-specified subgroup and meta-regression analyses. Weighted and standard mean difference (WMD/SMD), risk ratio (RR) ±95% confidence intervals (CIs), number needed to treat (NNT), and number needed to harm (NNH) were calculated. Eleven studies (n = 818, duration = 10.2±5.5 weeks) were identified for meta-analysis. Adjunctive ECT was superior to antipsychotic monotherapy regarding (1) symptomatic improvement at last-observation endpoint with an SMD of -0.67 (p<0.00001; I(2) = 62%), separating the two groups as early as weeks 1-2 with an SMD of -0.58 (p<0.00001; I(2) = 0%); (2) study-defined response (RR = 1.48, p<0.0001) with an NNT of 6 (CI = 4-9) and remission rate (RR = 2.18, p = 0.0002) with an NNT of 8 (CI = 6-16); (3) PANSS positive and general symptom sub-scores at endpoint with a WMD between -3.48 to -1.32 (P = 0.01 to 0.009). Subgroup analyses were conducted comparing double blind/rater-masked vs. open RCTs, those with and without randomization details, and high quality (Jadad≥adadup analyses were Jadad<3) studies. The ECT-antipsychotic combination caused more headache (p = 0.02) with an NNH of 6 (CI = 4-11) and memory impairment (p = 0.001) with an NNH of 3 (CI = 2-5). The use of ECT to augment antipsychotic treatment (clozapine excepted) can be an effective treatment option for TRS, with increased frequency of self-reported memory impairment and headache.

    Catatonia as a clozapine-withdrawal syndrome has only been documented in the medical literature as case reports. We are reporting a case in which a 32-year-old man develops a catatonic state upon withdrawal of clozapine. The state was quite severe and needed ICU admission. The course was chronic and intermittent which we think was caused by the poor adherence to antipsychotics. The importance of identifying such cases early is underlined. PMID:26788394

  12. Generic clozapine: a cost-saving alternative to brand name clozapine?

    As a consequence of its prevalence, early onset and chronicity, schizophrenia imposes clinical and economic impediments to healthcare practitioners and society alike. Among the many antipsychotics available to treat the symptoms of this devastating illness, clozapine has emerged and differentiated itself from the others as the agent most efficacious for the treatment of refractory patients. Since the patent for Clozaril (Novartis) expired in 1998, three manufacturers of generic clozapine have submitted abbreviated new drug applications to the US FDA for review and approval to market a generic clozapine product. In each case, the US FDA deemed the generic formulations to be bioequivalent to the brand name Clozaril. Apart from case reports, industry-sponsored studies have been conducted comparing Clozaril with two generic formulations. In one case, a generic formulation of clozapine manufactured by Creighton Products Corporation (formerly a subsidiary [generic house] of Sandoz Pharmaceuticals) was found to be bioequivalent to Clozaril. On the other hand, studies (sponsored by Novartis) have challenged the bioequivalence, therapeutic equivalence and interchangeability between Clozaril and a generic formulation manufactured by Zenith Goldline Pharmaceuticals (now IVAX Corporation). The IVAX Corporation-sponsored studies refuted these claims citing data from two patient registry database studies and one small clinical trial. Apart from a single in-house bioequivalence study, no further investigations have been conducted with a third generic formulation manufactured by Mylan Pharmaceutical. Although the clinical significance of the above discrepancy is obvious, what is less than obvious is the pharmacoeconomic implications that arises from this debate. Clearly, if the brand name and generic formulations are 'truly' bioequivalent, then the cost savings realised would be the difference in acquisition cost. On the other hand, if the various formulations are not

    1. Clozapine is a dibenzodiazepine neuroleptic which presents the advantage of not having undesirable neurological side-effects. Its efficacy for the treatment of the symptoms of schizophrenia is known, but the use of clozapine is limited to treatment-resistant schizophrenic patients as it induces agranulocytosis with a higher incidence than that of other neuroleptic drugs. 2. The present study was designed in order to evaluate the benefit/risk of chronic treatment. The analysis was performed using the files of schizophrenic patients. These patients were not stabilized by a classical neuroleptic treatment and/or presented individual secondary effects. 3. Clozapine induced neutropenia and 1 case of agranulocytosis in 3 females. Analysis of leukocyte expression highlighted some premonitory symptoms in patients who presented neutropenia. The observation of 2 to 3 early successive peaks in leukocyte expression (between the third and tenth week of treatment) could be predictive of neutropenia in the 3 to 4 months of treatment. 4. The patients who presented a lower leukocyte base-line following a peak had a higher risk, of developing neutropenia. This might explain some late accidents beyond the first six months of treatment. 5. The present study confirmed the advantages of clozapine treatment and demonstrated that the risk of neutropenia may be diminished by the detection of premonitory symptoms and the early monitoring of patients at risk i.e. female patients and subjects with a lower leukocyte base-line.

    PubMed

    Pascual, Julio

    2012-04-10

    We define chronic migraine as that clinical situation in which migraine attacks appear 15 or more days per month. Until recently, and in spite of its negative impact, patients with chronic migraine were excluded of the clinical trials. This manuscript revises the current treatment of chronic migraine. The first step should include the avoidance of potential precipitating/aggravating factors for chronic migraine, mainly analgesic overuse and the treatment of comorbid disorders, such as anxiety and depression. The symptomatic treatment should be based on the use of nonsteroidal anti-inflammatory agents and triptans (in this case < 10 days per month). It is necessary to avoid the use of combined analgesics, opioids and ergotamine-containing medications. Preventive treatment includes a 'transitional' treatment with nonsteroidal anti-inflammatory agents or steroids, while preventive treatment exerts its actions. Even though those medications efficacious in episodic migraine prevention are used, the only drugs with demonstrated efficacy in the preventive treatment of chronic migraine are topiramate and pericranial infiltrations of Onabotulinumtoxin A.

    Background The comparative antidepressant effects of clozapine and other atypical antipsychotics for schizophrenia remain elusive, leading us to examine this question using the data from the Clinical Antipsychotic Trials of Interventions Effectiveness phase 2E. Methods Ninety-nine patients who discontinued treatment with olanzapine, quetiapine, risperidone, or ziprasidone because of inadequate efficacy were randomly assigned to open-label treatment with clozapine (n=49) or double-blind treatment with another atypical antipsychotic not previously received in the trial (olanzapine [n=19], quetiapine [n=15], or risperidone [n=16]). The primary outcome was the Calgary Depression Scale for Schizophrenia (CDSS) total score. Antidepressant effects of clozapine and the other atypical antipsychotics were compared in patients with chronic schizophrenia and those with a major depressive episode (MDE) at baseline (i.e. ≥6 on the CDSS), using mixed models. Results No differences in the baseline CDSS total scores were found between the treatment groups regardless of presence of an MDE. Clozapine was more effective than quetiapine in antidepressant effects for chronic schizophrenia (p<.01 for the whole sample and p=.01 for those with an MDE), and comparable to olanzapine and risperidone. Conclusion The present findings suggest clozapine demonstrates superior antidepressant effects to quetiapine and comparable effects to olanzapine and risperidone in chronic schizophrenia regardless of presence of MDE. Given the indication of clozapine for treatment-resistant schizophrenia (TRS) and the negative impacts of depressive symptoms on clinical outcomes in schizophrenia, further research is warranted to investigate antidepressant effects of clozapine in TRS with an MDE.

    A successful clozapine support group operates from the principle that the drug is most successful when the person takes it as prescribed. The likelihood of initial and ongoing collaboration with treatment is increased when the tangible gains of the treatment can be experienced in the self and demonstrated in others. Clozapine support groups can advance the goals of collaboration and recovery.

    Non-adherence to medication is a major issue in the treatment of schizophrenia in general and in particular for those treated with clozapine. A reliable tool to quantify patients long-term adherence to clozapine is currently unavailable. Enhanced FL3 neutrophil granulocyte fluorescence was serendipitously observed in a small population of schizophrenic patients treated with clozapine. The present study was aimed at assessing the association between clozapine use and FL3-fluorescence. A cross-sectional study was performed using data from the Utrecht Patient Oriented Database (UPOD). A total of 38,390 inpatients were included, of which 124 (0.33%) used clozapine. FL3-fluorescence was significantly higher (U=240,179, P<0.001) in clozapine users (mean (SD)=90.5 (11.8)) than in non-users (mean (SD)=69.8 (3.3)). Observed FL3-fluorescence was found to increase with increasing clozapine dose. The area under the receiver operating characteristic curve was 0.95. Our results confirm the association between use of clozapine and elevated FL3-fluorescence. Further research is needed to unravel the underlying mechanism and to investigate the true potential of FL3-fluorescence as a clozapine-adherence biomarker in clinical practice.

    Schizophrenia is associated with activation of the brain immune system as reflected by increased brain levels of kynurenic acid (KYNA) and proinflammatory cytokines. Although antipsychotic drugs have been used for decades in the treatment of the disease, potential effects of these drugs on brain immune signaling are not fully known. The aim of the present study is to investigate the effects of chronic treatment with antipsychotic drugs on brain levels of cytokines and KYNA. Rats were treated daily by intraperitoneally administered haloperidol (1.5 mg/kg, n = 6), olanzapine (2 mg/kg, n = 6), and clozapine (20 mg/kg, n = 6) or saline (n = 6) for 30 days. Clozapine, but not haloperidol or olanzapine-treated rats displayed significantly lower cerebrospinal fluid (CSF) levels of interleukin-8 compared to controls. Whole brain levels of KYNA were not changed in any group. Our data suggest that the superior therapeutic effect of clozapine may be a result of its presently shown immunosuppressive action. Further, our data do not support the possibility that elevated brain KYNA found in patients with schizophrenia is a result of antipsychotic treatment. PMID:26448689

    To rechallenge with clozapine for a patient who previously has experienced neutropenia or leucopenia or during clozapine treatment is a difficult clinical decision. Herein, we analyzed the results of such a rechallenge in 19 patients. We analyzed all the reports, from the database of the pharmacovigilance department of the Argentine National Administration of Drugs, Foods, and Medical Devices, of patients who were rechallenged with clozapine after a leucopenia or a neutropenia. Nineteen cases of rechallenge after leucopenia or neutropenia were reported between 1996 and 2014. One third of the patients re-exposed to clozapine developed a new hematologic adverse reaction. The second blood dyscrasia was less severe in 83% of the cases and had a shorter median latency as compared with the first (8 weeks vs 182 weeks, P = 0.0045). There were no significant differences for demographic and clinical characteristics of patients who developed a second dyscrasia as compared with those who did not. The present study shows that almost 70% of the patients rechallenged with clozapine after a leucopenia or a neutropenia did not develop a new hematological adverse effect, whereas the remaining 30% had a faster but less serious neutropenia.

    Constipation is a common and sometimes fatal side effect of clozapine treatment. In this study, we aimed to identify factors associated with clozapine-induced constipation. Data on 202 outpatients stabilized on clozapine treatment were collected. Of these, 71 patients (35%) had a current prescription for laxatives (a proxy for the presence of constipation). Mean clozapine dose was 400.4 mg/day in those prescribed laxatives and 390.1 mg/day in those not prescribed laxatives (p = 0.67), while mean clozapine plasma concentration was 0.53 mg/l and 0.49 mg/l, respectively (p = 0.29). Patients using laxatives had on average 29% higher norclozapine concentrations (mean = 0.34 mg/l) than those who did not use laxatives (mean = 0.27 mg/l; p = 0.046). Laxative use was more common in female patients (49.1%) than male patients (29.1%; p < 0.01). Prescribers should be vigilant for constipation at any dose or plasma concentration of clozapine and should be mindful that male patients may be undertreated. Norclozapine concentrations may predict clozapine-induced constipation. PMID:26557981

    Summary A case is presented of a 25-year-old man with treatment-resistant paranoid schizophrenia whose only previous trial of clozapine had been stopped following a suspected clozapine-induced myocarditis. Due to the failure of his psychosis to respond to a number of antipsychotic treatments and augmentation strategies, clozapine was restarted on admission. His rechallenge was marked by intermittent pyrexia, tachycardia and elevated C-reactive protein (CRP), but eosinophilia was absent. Clozapine was started and then stopped twice following extensive investigation and with specialist cardiology consultation. Physical symptoms and CRP elevation resolved shortly after clozapine cessation. We believe this constituted an idiosyncratic systemic inflammatory response to clozapine treatment.

    Dysphagia is listed as a 'rare' side effect following clozapine treatment. In this case report, we describe how significant clozapine-induced dysphagia has led to significant reduction of nutritional intake with subsequent substantial weight loss. An 18-year-old single man with an established diagnosis of treatment-resistant paranoid schizophrenia recovered well on a therapeutic dose of clozapine. However, he was noted to lose weight significantly (up to 20% of his original weight) as the dose was uptitrated. This was brought about by development of dysphagia, likely to be due to clozapine. Addition of nutritional supplementary liquids and initiation of a modified behavioural dietary/swallowing programme, while repeatedly mastering the Mendelsohn manoeuvre technique, alleviated the swallowing difficulties and restored his weight.

    Failure of an acute inflammatory response to resolve a wound infection heralds a cascade of events that affects the host and pathogens, culminating in a chronic, refractory condition. The factors contributing to this outcome include immune compromise of the host, antimicrobial resistance, wound-healing deficiencies, and the adherence of pathogens to themselves and wound surfaces via an impenetrable, resistant biofilm. To eradicate chronic infection, the pathogens, biofilm, surfaces available for adherence, and compromised tissue must be removed.

    Patients with borderline personality disorder (BPD) show significant impairment in functioning, particularly in the interpersonal and social domains. Prior reports suggest that clozapine may be effective in the management of BPD. We present the case of a patient with BPD who experienced persistent suicidal ideation and was treated with clozapine at a state psychiatric hospital. After treatment failure with other psychotropic medications, clozapine medication was initiated; not only did suicidal ideation cease, but social and professional functioning also greatly improved to the point of no longer requiring intensive levels of observation or restrictive procedures. Clozapine appears to be efficacious in the management of suicide attempts and self-injurious behavior. Moreover, it appears to be promising as a therapeutic measure for ameliorating the global functioning of patients with severe BPD. Larger, randomized, blinded, and controlled prospective studies are needed to confirm these findings and to determine optimal dosage. PMID:27121437

    Clozapine is effective in treatment resistant schizophrenia; however, it is underutilised probably because of its side effects. The side effects are also the potential reasons for clozapine discontinuation. A mandatory requirement for its use is regular monitoring of white blood cell count and absolute neutrophil count. However there are many side effects that need monitoring in clinical practice considering their seriousness. This article tries to summarise the clinical concerns surrounding the serious side effects of clozapine some of which are associated with fatalities and presents a comprehensive way to monitor patients on clozapine in clinical practice. It emphasizes the need to broaden the monitoring beyond the mandatory investigations. This may help in improving the safety in clinical practice and increasing clinician confidence for greater and appropriate use of this effective intervention. PMID:27776383

    Background Clozapine has been serving as the gold standard medication for patients with treatment-resistant schizophrenia who failed to respond to other antipsychotics. However, factors affecting response to this medication have not been comprehensively reviewed recently. Methods: In order to find factors associated with response to clozapine in schizophrenia, a literature search was conducted using PubMed through January 2011 with keywords of clozapine, response, and schizophrenia. Cross-referencing of relevant articles was also performed. Factors were arbitrarily classified into the following: demographic/clinical, oral dosage/pharmacokinetic, biochemical, (electro)physiological, genetic, imaging, and combinations. Results A synthesis from 280 articles indicated that demographic and clinical variables such as high baseline symptoms and low premorbid functioning have not been particularly useful in predicting response to clozapine. Pharmacokinetic evidence points to a threshold clozapine level of 350 ng/ml but in a context of significant inter- as well as intra-individual variability. Pharmacokinetic perspectives appear to have more implication in special situations including poor response, suspected toxicity and nonadherence. A number of laboratory-based studies have reported on many potential candidates for response prediction to clozapine, however, reproducibility, specificity, robustness of the findings, as well as clinical feasibility and cost-effectiveness all pose a significant practical challenge, in relation with the fact that pathophysiological bases of treatment resistance in schizophrenia largely remain to be elucidated. Conclusions No unequivocal factors to clozapine response were found despite a relatively rich body of the literature, which calls for more works on this important topic. Clozapine level of 350 ng/ml appears to be useful in case of nonresponse. PMID:22506438

  15. Chronic Pruritus: Clinics and Treatment

    Grundmann, Sonja

    2011-01-01

    Chronic pruritus, one of the main symptoms in dermatology, is often intractable and has a high impact on patient's quality of life. Beyond dermatologic disorders, chronic pruritus is associated with systemic, neurologic as well as psychologic diseases. The pathogenesis of acute and chronic (>6 weeks duration) pruritus is complex and involves in the skin a network of resident (e.g., sensory neurons) and transient inflammatory cells (e.g., lymphocytes). In the skin, several classes of histamine-sensitive or histamine-insensitve C-fibers are involved in itch transmission. Specific receptors have been discovered on cutaneous and spinal neurons to be exclusively involved in the processing of pruritic signals. Chronic pruritus is notoriously difficult to treat. Newer insights into the underlying pathogenesis of pruritus have enabled novel treatment approaches that target the pruritus-specific pathophysiological mechanism. For example, neurokinin-1 antagonists have been found to relieve chronic pruritus. PMID:21738356

    This study examined how repeated olanzapine (OLZ) or clozapine (CLZ) treatment in adolescence alters sensitivity to the same drug in adulthood in the phencyclidine (PCP) hyperlocomotion model. Male adolescent Sprague-Dawley rats (postnatal day (P) 44–48) were first treated with OLZ (1.0 or 2.0 mg/kg, subcutaneously (sc)) or CLZ (10.0 or 20.0 mg/kg, sc) and tested in the PCP (3.2 mg/kg, sc)-induced hyperlocomotion model for five consecutive days. Then a challenge test with OLZ (0.5 mg/kg) or CLZ (5.0 mg/kg) was administered either during adolescence (~P 51) or after the rats matured into adults (~P 76 and 91). During adolescence, repeated OLZ or CLZ treatment produced a persistent inhibition of PCP-induced hyperlocomotion across the five test days. In the challenge test during adolescence, rats previously treated with OLZ did not show a significantly stronger inhibition of PCP-induced hyperlocomotion than those previously treated with vehicle (VEH). In contrast, those previously treated with CLZ showed a weaker inhibition than the VEH controls. When assessed in adulthood, the enhanced sensitivity to OLZ and the decreased sensitivity to CLZ were detected on ~P 76, even on ~P 91 in the case of OLZ. These findings suggest that adolescent OLZ or CLZ exposure can induce long-term alterations in antipsychotic response that persist into adulthood. PMID:24257809

    The development of therapeutic strategies to effectively treat negative symptoms remains one of the primary goals in the treatment of schizophrenia. Mirtazapine is the first of a new class of dual action compounds, the noradrenergic and specific serotonergic antidepressants (NaSSa), whose activity is related to the enhancement of noradrenergic and serotonergic transmission by a presynaptic alpha2 antagonism and postsynaptic 5-HT2 and 5-HT3 antagonism, respectively. This study was a 8-week double-blind, randomized, placebo-controlled trial of 30 mg adjunctive mirtazapine to clozapine therapy in 24 patients with DSM-IV schizophrenia. The main finding at the end of the trial was a significant reduction on the Scale for the Assessment of Negative Symptoms (SANS) total scores in the mirtazapine group compared to placebo (P<0.01) with a significant improvement on the SANS subscales avolition/apathy and anhedonia/asociality. The Brief Psychiatric Rating Scale total score at week 8 showed superiority of mirtazapine over placebo. These findings suggest a potential role for mirtazapine as an augmentation strategy in the treatment of negative symptoms of schizophrenia. PMID:15076014

    Brain-derived neurotrophic factor (BDNF) regulates the survival and growth of neurons, and influences synaptic efficiency and plasticity. Peripheral BDNF levels in patients with schizophrenia have been widely reported in the literature. However, it is still controversial whether peripheral levels of BDNF are altered in patients with schizophrenia. The peripheral BDNF levels previously reported in patients with schizophrenia were total BDNF (proBDNF and mature BDNF) as it was unable to specifically measure mature BDNF due to limited BDNF antibody specificity. In this study, we examined whether peripheral levels of mature BDNF were altered in patients with treatment-resistant schizophrenia. Matrix metalloproteinase-9 (MMP-9) levels were also measured, as MMP-9 plays a role in the conversion of proBDNF to mature BDNF. Twenty-two patients with treatment-resistant schizophrenia treated with clozapine and 22 age- and sex-matched healthy controls were enrolled. The plasma levels of mature BDNF and MMP-9 were measured using ELISA kits. No significant difference was observed for mature BDNF however, MMP-9 was significantly increased in patients with schizophrenia. The significant correlation was observed between mature BDNF and MMP-9 plasma levels. Neither mature BDNF nor MMP-9 plasma levels were associated clinical variables. Our results do not support the view that peripheral BDNF levels are associated with schizophrenia. MMP-9 may play a role in the pathophysiology of schizophrenia and serve as a biomarker for schizophrenia.

    Clozapine is an antipsychotic medication with superior efficacy in treatment-refractory schizophrenia. The molecular basis of clozapine’s therapeutic profile is not well understood. We studied behavioral effects of clozapine in Caenorhabditis elegans to identify novel pathways that modulate clozapine’s biological effects. Clozapine stimulated egg laying in C. elegans in a dose-dependent manner. This effect was clozapine-specific, as it was not observed with exposure to a typical antipsychotic, haloperidol or an atypical antipsychotic, olanzapine. A candidate gene screen of biogenic amine neurotransmitter systems identified signaling pathways that mediate this clozapine-specific effect on egg laying. Specifically, we found that clozapine-induced increase in egg laying requires tyramine biosynthesis. To test the implications of this finding across species, we explored whether trace amine systems modulate clozapine’s behavioral effects in mammals by studying trace amine-associated receptor 1 (TAAR1) knockout mice. Clozapine increased pre-pulse inhibition (PPI) in wild-type mice. This increase in PPI was abrogated in TAAR1 knockout mice, implicating TAAR1 in clozapine-induced PPI enhancement. In transfected mammalian cell lines, we found no TAAR activation by antipsychotics, suggesting that modulation of trace amine signaling in mice does not occur directly at the receptor itself. In summary, we report a heretofore-unknown role for trace amine systems in clozapine-mediated effects across two species: C. elegans and mice. PMID:21529784

    Clozapine has been associated with a 1% incidence of agranulocytosis. The formation of an oxidized intermediate clozapine metabolite has been implicated in direct polymorphonuclear (PMN) toxicity. We utilized two separate systems to analyze the role of oxidized clozapine in inducing apoptosis in treated cells. Human PMN cells incubated with clozapine (0-10 {mu}M) in the presence of 0.1 mM H{sub 2}O{sub 2} demonstrated a progressive decrease of surface CD16 expression along with increased apoptosis. RT-PCR analysis showed decreased CD16 but increased FasL gene expression in clozapine-treated PMN cells. No change in constitutive Fas expression was observed in treated cells. In HL-60 cells induced to differentiate with retinoic acid (RA), a similar increase in FasL expression, but no associated changes in CD16 gene expression, was observed following clozapine treatments. Our results demonstrate increased FasL gene expression in oxidized clozapine-induced apoptotic neutrophils suggesting that apoptosis in granulocytes treated with clozapine involves Fas/FasL interaction that initiates a cascade of events leading to clozapine-induced agranulocytosis.

    Clozapine is a distinctive antipsychotic agent, having a unique clinical profile and an idiosyncratic safety profile. More so than with other agents, the weighting of its adverse event profile is critical, in order to counterbalance its clear clinical advantages. The safety issues with clozapine are in a number of areas, some of which are considered medical emergencies and potentially life-threatening. These include haematological (neutropenia and agranulocytosis), CNS (seizures), cardiovascular (myocarditis and cardiomyopathy), metabolic (diabetes), gastrointestinal and neuromuscular. Understanding the safety profile of clozapine allows an informed use of the agent that can maximise its clear clinical benefit and minimise the known risks.

    Recently, extensive efforts have been made to understand the rate of energy expenditure and the weight gain associated with atypical antipsychotic treatment, including identification of markers of obesity risk. In recent years, leptin, an adipocyte hormone, has gained significant interest in psychiatric disorders. S100B has been considered as a surrogate marker for astrocyte-specific damage in neurologic disorders. Also, S100B has been detected in adipose with concentration as high as nervous tissue as a second release source. In this study we evaluated the relationship between S100B and leptin in schizophrenic patients under treatment with clozapine and risperidone.This study included 19 patients meeting the DSM-IV-TR criteria for schizophrenia, having body mass index (BMI) of 16- 25 kg/m2 and suffering schizophrenia for more than 3 years and from this study. Twenty five healthy controls were group matched for age and gender whose BMI was 16-25 kg/m2. Serum S100B and leptin levels and positive and negative symptom scale (PANSS) were assessed at admission and after six weeks. During the study, S100B showed a strong and negative correlation with leptin (r = -0.5, P = 0.01). Also, there were negative correlation between serum S100B level and PANSS negative subscale after 6 weeks of treatment (r = -0.048, P = 0.8). Positive correlation between leptin level and PANSS suggested a potential role for leptin which can mediate the link between antipsychotic induced weight gain and therapeutic response in schizophrenia.

    Objective Clozapine is the most effective antipsychotic for treatment refractory people with schizophrenia, yet many patients only partially respond. Accumulating preclinical and clinical data suggest benefits with minocycline. We tested adjunct minocycline to clozapine in a 10 week, double blind placebo-controlled trial. Primary outcomes tested were positive and cognitive symptoms, while avolition, anxiety/depression and negative symptoms were secondary outcomes. Methods Schizophrenia and schizoaffective participants (N=52) with persistent positive symptoms were randomized to receive adjunct minocycline (100 mg oral capsule twice daily) (N=29) or placebo (N=23). Results Brief Psychiatric Rating Scale (BPRS) psychosis factor (p=0.098, effect size ES=0.39) and BPRS total score (p=0.075, effect size 0.55) were not significant. A ≥30% change in total BPRS symptoms was observed in 7/28 (25%) among minocycline and 1/23 (4%) among placebo participants, respectively (p=0.044). Global cognitive function (MATRICS Consensus Cognitive Battery, MCCB) did not differ, although there was a significant variation in size of treatment effects among cognitive domains (p=0.03), with significant improvement in working memory favoring minocycline (p=0.023, ES 0.41). The SANS total score did not differ, but significant improvement in avolition with minocycline was noted (p=0.012, ES=0.34). Significant improvement in the BPRS anxiety/depression factor was observed with minocycline (p=0.028, ES=0.49). Minocycline was well tolerated with significantly fewer headaches and constipation compared to placebo. Conclusion Minocycline’s effect on the MCCB composite score and positive symptoms were not statistically significant. Significant improvements with minocycline were seen in working memory, avolition and anxiety/depressive symptoms in a chronic population with persistent symptoms. Larger studies are needed to validate these findings. PMID:26082974

    Clozapine has been demonstrated to be useful for treating refractory schizophrenia. However, hypersalivation occurs in 31.0- 97.4% of the patients treated with clozapine. Accordingly, some patients who are disturbed by their hypersalivation refuse to continue with clozapine treatment. This study investigated the efficacy of the anticholinergic agent scopolamine butylbromide against clozapine-induced hypersalivation. Five schizophrenia patients were coadministered scopolamine butylbromide (30-60 mg/ day) for 4 weeks. At the baseline and after 4 weeks' treatment, we subjectively evaluated hypersalivation using a visual analog scale and objectively assessed it using the Drooling Severity Scale and Drooling Frequency Scale. As a result, improvements in the patients' Drooling Severity Scale and Drooling Frequency Scale scores, but no improvements in their visual analog scale scores, were observed after scopolamine butylbromide treatment. These results indicate that at least some schizophrenic patients with clozapine-induced hypersalivation would benefit from scopolamine butylbromide treatment. We conclude that clozapine-induced hypersalivation is one factor of stress to patients. Subjective hypersalivation was not improved, but objective hypersalivation was, by scopolamine butylbromide treatment. However, scopolamine butylbromide and clozapine possess anticholinergic effects so clinicians should closely monitor patients who take scopolamine butylbromide.

    Increased neuronal densities in subcortical white matter have been reported for some cases with schizophrenia. The underlying cellular and molecular mechanisms remain unresolved. We exposed 26 young adult macaque monkeys for 6 months to either clozapine, haloperidol or placebo and measured by structural MRI frontal gray and white matter volumes before and after treatment, followed by observer-independent, flow-cytometry-based quantification of neuronal and non-neuronal nuclei and molecular fingerprinting of cell-type specific transcripts. After clozapine exposure, the proportion of nuclei expressing the neuronal marker NeuN increased by approximately 50% in subcortical white matter, in conjunction with a more subtle and non-significant increase in overlying gray matter. Numbers and proportions of nuclei expressing the oligodendrocyte lineage marker, OLIG2, and cell-type specific RNA expression patterns, were maintained after antipsychotic drug exposure. Frontal lobe gray and white matter volumes remained indistinguishable between antipsychotic-drug-exposed and control groups. Chronic clozapine exposure increases the proportion of NeuN+ nuclei in frontal subcortical white matter, without alterations in frontal lobe volumes or cell type-specific gene expression. Further exploration of neurochemical plasticity in non-human primate brain exposed to antipsychotic drugs is warranted.

    Objective Although numerous reports suggest that different atypical antipsychotics can exacerbate or induce (de novo) obsessive-compulsive symptoms, there is no report of the development of ego-dystonic, suicidal obsessions during treatment with these medications. Here, the authors report the first case of clozapine-induced suicidal obsessions. Method The authors report a case of a patient diagnosed with bipolar disorder and who developed suicidal obsessions in the weeks after the dose of clozapine was increased from 150 mg/day to 300 mg/day. Results Symptoms quickly resolved after the treatment with clozapine was changed to the treatment with quetiapine and sodium valproate. Suicidal obsessions decreased promptly, within a few days, and disappeared completely when the dose of clozapine was 100 mg/day, quetiapine 600 mg/day, and sodium valproate 900 mg/day, 16 days after the initiation of changes in the medications. Conclusion The case report emphasizes the crucial need of differentiation between genuine suicidal desires and ego-dystonic suicidal obsessions. The authors suggest that in similar cases a change in antipsychotic medications to those with stronger antidopaminergic properties and lower 5HT2 receptor affinity should be considered, but also assume that the use of sodium valproate in treatment of obsessive-compulsive symptoms deserves further study.

  14. Historical treatment of chronic hepatitis B and chronic hepatitis C.

    Interferon is currently considered to be the only accepted effective treatment for chronic viral hepatitis. A history of the treatment of chronic hepatitis B and C before the use of interferon is presented here. Hepatitis B virus does not seem to be directly cytopathic and the disease is known to be modulated largely by the host's immune response. Experience with immunosuppressant and immunostimulant drugs and a wide variety of antiviral agents, however, has indicated that none of these are of any benefit in patients with chronic hepatitis B, with the possible exception of adenine arabinoside. In view of the much more recent identification of the hepatitis C virus, studies of therapy for chronic hepatitis C are inevitably less extensive. A pilot study using acyclovir in patients with chronic non-A, non-B hepatitis did not show any benefit, although the treatment period may have been too short for the results to be conclusive. The only agent other than alpha interferon to be tried in chronic hepatitis C is ribavirin, which may have some activity. Many of the agents studied in chronic hepatitis B should also be investigated for the treatment of patients with chronic hepatitis C. PMID:8314494

    There are many conditions in which chronic orofacial pain is a major diagnostic and therapeutic problem. It is generally accepted that surgical treatment for these chronic pain problems should be resorted to only when more conservative treatments have been ineffective. Literature concerning selected orofacial pain problems is reviewed and the indications for surgical management are discussed. PMID:6370045

    Medical charts of 480 schizophrenic in-patients (581 treatments) were analysed to evaluate the efficacy and side-effects of clozapine. Clozapine treatment lasted for mean 49 (s.d. 38) days. Of the sample, 11.0% showed worsening or no change, 31.5% slight improvement, 53.0% marked improvement and 4.5% almost total reduction of symptoms. At least one major side-effect occurred in 68.0% of patients. A combination of clozapine with classical neuroleptics, antidepressants, benzodiazepines or lithium is tolerated by most patients, but increases the incidence of some side-effects. Clozapine treatment had to be discontinued because of severe side-effects in 8.6% of patients. In 81 schizophrenic out-patients, clozapine significantly reduced the days of in-patient treatment and number of hospital readmissions. Two patients developed leucopenia but had no complications after clozapine withdrawal. This study indicates a satisfactory benefit/risk ratio and compliance in most of the patients.

    This report describes the efficacy of combined use of aripiprazole in the treatment of a patient with clozapine induced enuresis. Aripiprazole acts as a potential dopamine partial agonist and the dopamine blockade in the basal ganglia might be one of the causes of urinary incontinence and enuresis. We speculate that aripiprazole functioned as a D2 agonist in hypodopaminergic state of basal ganglia caused by clozapine and maintained dopamine level that would improve enuresis ultimately.

    Chronic migraine (CM) is defined as headache occurring more than fifteen days/month for at least three consecutive months, with headache having the clinical features of migraine without aura for at least eight days per month. Recently, new treatment options became available in chronic migraine patients. Topiramate is effective in chronic migraine, in the presence or absence of medication overuse, and/or other migraine prophylaxis. Efficacy of onabotulinumtoxin A as a preventive treatment of chronic migraine has been shown in the PREEMPT studies. Occipital nerve stimulation (ONS) is an invasive treatment for refractory chronic headaches. ONS has encouraging results in refractory chronic migraine patients in commercially funded, multi-centre randomized trials. PMID:25705314

    We describe a case in which a patient's clinical response to clozapine appears to correlate positively with his serum triglyceride concentrations. We propose that the observed clinical response may partly be the result of the physical interaction of clozapine with the very low-density lipoproteins. We base this supposition on our previous in-vitro study showing that the plasma distribution of clozapine is significantly altered by increases in plasma triglyceride concentrations. Although this case only represents one patient, it highlights the possibility that serum lipids may be potential contributors to the clinical effectiveness of clozapine. PMID:12131604

    Aim: To evaluate the efficacy and safety of the augmentation of clozapine with aripiprazole in patients with treatment-resistant schizoaffective and psychotic bipolar disorders in a retrospective manner. Pharmacodynamic and pharmacokinetic interactions between the two drugs were also investigated. Patients: Three men and 4 women (median age 36 and 40 years, respectively) who had mean scores at BPRS and CGI-Severity of 59.1±12.0 and 5.4±0.5, respectively, were treated with clozapine (mean dose 292.9±220.7 mg/day). Patients received an adjunctive treatment with aripiprazole (mean dose 6.8 ± 3.7 mg/day). Clozapine, norclozapine and aripiprazole plasma levels were measured by means of a high performance liquid chromatograpy with UV detection. Results: Total scores at BPRS decreased significantly (from 59.1±12.0 to 51.1±15.6, p=0.007) after aripirazole augmentation. In particular, the factors “thought disorder” (from 10.4±4.4 to 9.0±4.5, p=.047) and “anergia” (from 10.0±2.7 to 8.0±2.4, p=.018) significantly improved. Concomitant administration of aripiprazole and clozapine did not result in an increase in side effects over the period of treatment. Dose-normalized plasma levels of both clozapine and norclozapine and the clozapine/norclozapine metabolic ratio in all patients did not vary as well. Conclusion: The augmentation of clozapine with aripirazole was safe and effective in severe psychotic schizoaffective and bipolar disorders which failed to respond to atypical antipsychotics. A possible pharmacokinetic interaction between clozapine and aripiprazole does not account for the improved clinical benefit obtained after aripiprazole augmentation. PMID:20648219

    A Caucasian male in his early twenties suffering from treatment resistant schizophrenia was started on clozapine. After three days he developed tachycardia, a common side effect of clozapine induction. He had one temperature spike (38.9°C) on day ten after induction but remained clinically well. An ECG and blood tests were normal. Due to persistent tachycardia and an episode of collapse whilst seated on day 12, he was admitted to hospital for further investigation. A diagnosis of myocarditis was confirmed as a result of elevated cardiac enzyme levels and an echocardiogram. Following withdrawal of clozapine, supportive management, and initiation of cardiac medication, the patient made a successful recovery. He will be followed up with the cardiology team to ensure that his heart function returns to normal. Given the incidence of clozapine-induced myocarditis, the associated mortality risk, and diagnostic difficulties, this case raises questions about whether a formal system for identifying myocarditis should be adopted.

    2016-08-01

    Chronic migraine has a great detrimental influence on a patient's life, with a severe impact on socioeconomic functioning and quality of life. Chronic migraine affects 1-2% of the general population, and about 8% of patients with migraine; it usually develops from episodic migraine at an annual conversion rate of about 3%. The chronification is reversible: about 26% of patients with chronic migraine go into remission within 2 years of chronification. The most important modifiable risk factors for chronic migraine include overuse of acute migraine medication, ineffective acute treatment, obesity, depression and stressful life events. Moreover, age, female sex and low educational status increase the risk of chronic migraine. The pathophysiology of migraine chronification can be understood as a threshold problem: certain predisposing factors, combined with frequent headache pain, lower the threshold of migraine attacks, thereby increasing the risk of chronic migraine. Treatment options include oral medications, nerve blockade with local anaesthetics or corticoids, and neuromodulation. Well-defined diagnostic criteria are crucial for the identification of chronic migraine. The International Headache Society classification of chronic migraine was recently updated, and now allows co-diagnosis of chronic migraine and medication overuse headache. This Review provides an up-to-date overview of the classification of chronic migraine, basic mechanisms and risk factors of migraine chronification, and the currently established treatment options.

    Constipation is a frequently overlooked side effect of clozapine treatment that can prove fatal. We conducted a systematic review and meta-analysis to estimate the prevalence and risk factors for clozapine-associated constipation. Two authors performed a systematic search of major electronic databases from January 1990 to March 2016 for articles reporting the prevalence of constipation in adults treated with clozapine. A random effects meta-analysis was conducted. A total of 32 studies were meta-analyzed, establishing a pooled prevalence of clozapine-associated constipation of 31.2% (95% CI: 25.6–37.4) (n = 2013). People taking clozapine were significantly more likely to be constipated versus other antipsychotics (OR 3.02 (CI: 1.91–4.77), p < 0.001, n = 11 studies). Meta-regression identified two significant study-level factors associated with constipation prevalence: significantly higher (p = 0.02) rates of constipation were observed for those treated in inpatient versus outpatient or mixed settings and for those studies in which constipation was a primary or secondary outcome measure (36.9%) compared to studies in which constipation was not a specified outcome measure (24.8%, p = 0.048). Clozapine-associated constipation is common and approximately three times more likely than with other antipsychotics. Screening and preventative strategies should be established and appropriate symptomatic treatment applied when required. PMID:27271593

    The use of clozapine, an effective antipsychotic drug used in treatment-resistant schizophrenia, is associated with adverse effects. Sialorrhea is one such effect, which can be distressing for many patients. Studies on the pharmacogenetics of the adverse effects of clozapine are limited. The aim of the present study was to determine whether clozapine-induced sialorrhea is associated with a 120 base-pairs (bp) tandem duplication polymorphism in the dopamine receptor subtype D4 (DRD4) gene. Ninety-five patients, mean age 35.43±9.43 years, with treatment-resistant schizophrenia and on clozapine were included in the study. Development of sialorrhea in response to the drug, as manifested by drooling of saliva, was documented in 45 (47.4%) patients. Genotyping of the patients was carried out to detect the presence of the polymorphism of interest. Clozapine-induced sialorrhea was found to be associated significantly with the 120-bp duplication in DRD4. The association was found to fit a log-additive model with an odds ratio of 2.95 (95% confidence interval 1.51-5.75; P=0.0006). Thus, the presence of the 120-bp duplication in DRD4 appears to confer a risk for sialorrhea in response to clozapine therapy. The underlying pathophysiology and clinical significance of this phenomenon warrant further investigation.

    Information on dose- and concentration-related clinical effects of clozapine treatment in children and adolescents is scarce. This study aimed to examine the relationship between dose, serum concentration, and clinical outcome as well as the influencing factors thereof in paediatric patients treated with clozapine. Data from a routine Therapeutic Drug Monitoring (TDM) service between 2004 and 2014 were studied in 68 patients, aged 11-18 years. Severity of illness, therapeutic effectiveness and adverse drug reactions (ADRs) were assessed by standardized means. A relationship between the daily dose (mean 319 mg, 4.9 mg/kg) and serum concentration (mean 387 ng/ml) of clozapine was found with the variation in dose explaining 30 % of the variability in clozapine serum concentrations. Also gender contributed to the variability, however, no influence of age or concomitant medications was detected. Furthermore, a significant association was found between clozapine serum concentration and the occurrence of ADRs. Patients without ADRs had a lower mean serum concentration than those with mild (261.4 vs 407.3 ng/ml, P = 0.018) and moderate ADRs (261.4 vs 416.3 ng/ml, P = 0.028). As clozapine was estimated to be effective in lower blood concentrations, guidance on a possibly lower therapeutic range of clozapine serum levels in paediatric patients is provided. With ADRs increasing under higher concentrations, TDM is strongly recommended in paediatric clozapine therapy for individualized dosing. Dose adjustment in females also might be reasonable according to gender-related differences in serum concentrations. However, regarding the limitations of this study results should be validated in larger studies with more standardized designs. PMID:27221285

    Developments increasing our understanding of chronic urticaria have resulted in the simplification and improvement of available treatments. Currently, many treatments target mast cell mediators, but we can now disrupt mast cell activation with the anti-IgE antibody omalizumab, which has markedly advanced the treatment landscape for patients with difficult-to-treat urticaria. Current guidelines provide a framework for the management and treatment of patients with CU but, as each patient is different, knowledge and experience of specialist dermatologists and allergists are key to effective pharmacotherapy. This article reviews the different therapeutic options for patients with chronic spontaneous urticaria (also called chronic idiopathic urticaria) or chronic inducible urticaria and discusses management of special populations or special circumstances related to CU.

    One underrecognized adverse event of clozapine is the emergence or worsening of obsessive-compulsive symptoms (OCS). OCS, particularly violent thoughts, can be inaccurately described as psychosis and result in a misdiagnosis. We report a case of a 42-year-old man, initially diagnosed with schizoaffective, who was placed on clozapine for the management of "violent delusions." However, clozapine led to a worsening of these violent thoughts resulting in suicidal ideation and hospitalization. After exploration of the intrusive thoughts and noting these to be egodystonic, clearly disturbing, and time consuming, an alternative diagnosis of obsessive-compulsive disorder (OCD) was made. Clozapine was inevitably discontinued resulting in a significant reduction of the intrusive thoughts without emergence of psychosis or adverse events. While an overlapping phenomenology between OCD and psychotic disorders has been described, clozapine and other antiserotonergic antipsychotics have been implicated with the emergence or worsening of OCS. Unique to our case is that the patient's obsessions had been treated as psychosis leading to the inadequate treatment of his primary illness, OCD. This case highlights the potential for OCD to masquerade as a psychotic disorder and reminds clinicians that clozapine may worsen OCS. PMID:27313938

    Rationale Nicotinic systems in the hippocampus play important roles in memory function. Decreased hippocampal nicotinic receptor concentration is associated with cognitive impairment in schizophrenia and Alzheimer's disease. Methods We modeled in rats the cognitive effects of chronic decrease in hippocampal α7 or α4β2 receptors with 4-week continuous bilateral local infusions of the α7 nicotinic antagonist methyllycaconitine (MLA) or the α4β2 antagonist dihydro-β-erythroidine (DHβE). The working memory effects of these infusions were assessed by performance on the radial-arm maze. To test the effect of antipsychotic medication, we gave acute injections of clozapine and to determine the impact of nicotine, which is widely used by people with schizophrenia approximately half of the rats received chronic systemic infusions of nicotine. Results Chronic ventral hippocampal DHβE infusion caused a significant (p<0.001) working memory impairment. Acute systemic clozapine (2.5 mg/kg) caused a significant (p<0.005) working memory impairment in rats given control aCSF hippocampal infusions. Clozapine significantly (p<0.025) attenuated the memory deficit caused by chronic hippocampal DHβE infusions. Chronic ventral hippocampal infusions with MLA did not significantly affect the working memory performance in the radial-arm maze, but it did significantly (p<0.05) potentiate the memory impairment caused by 1.25 mg/kg of clozapine. Chronic systemic nicotine did not significantly interact with these effects. Conclusions The state of nicotinic receptor activation in the ventral hippocampus significantly affected the impact of clozapine on working memory with blockade of α7 nicotinic receptors potentiating clozapine-induced memory impairment and blockade of α4β2 receptors reversing the clozapine effect from impairing to improving memory.

  13. The diagnosis and treatment of chronic migraine

    PubMed Central

    2015-01-01

    Migraine is the most common disabling brain disorder. Chronic migraine, a condition characterized by the experience of migrainous headache on at least 15 days per month, is highly disabling. Patients with chronic migraine present to primary care, are often referred for management to secondary care, and make up a large proportion of patients in specialist headache clinics. Many patients with chronic migraine also have medication overuse, defined as using a compound analgesic, opioid, triptan or ergot derivative on at least 10 days per month. All doctors will encounter patients with chronic headaches. A basic working knowledge of the common primary headaches, and a rational manner of approaching the patient with these conditions, allows a specific diagnosis of chronic migraine to be made quickly and safely, and by making this diagnosis one opens up a substantial number of acute and preventive treatment options. This article discusses the current state of management of chronic migraine. PMID:25954496

  14. Impramine, fluoxetine and clozapine differently affected reactivity to positive and negative stimuli in a model of motivational anhedonia in rats.

    Anhedonia is a relevant symptom in depression and schizophrenia. Chronic stress exposure induces in rats escape deficit, disrupts the dopaminergic response to palatable food and the competence to acquire sucrose self-administration (SA), thus configuring a possible model of motivational anhedonia. Repeated lithium administration reverts stress effects and brings back to control values the breaking point (BP) score, a measure of reward motivation. In this study, we tested on this model two antidepressants, imipramine and fluoxetine, and two antipsychotics, haloperidol and clozapine. The dopaminergic response to sucrose consumption was studied in non food-deprived rats in terms of dopamine D1 receptor signaling in the nucleus accumbens shell (NAcS). More specifically, we studied the modifications in dopamine and cAMP-regulated phosphoprotein of Mr 32,000 (DARPP-32) phosphorylation pattern following sucrose consumption. Fluoxetine reverted the escape deficit and showed no effects on dopaminergic response and sucrose SA. Imipramine reverted sucrose SA and dopamine response deficit in half of the rats and the escape deficit in all animals. Haloperidol did not affect stress-induced deficits. Clozapine-treated rats recovered the dopaminergic response to sucrose consumption and the competence to acquire sucrose SA, although they still showed the escape deficit, thus confirming that motivation toward reward may be dissociated from that to punishment escape. These results indicate that imipramine or fluoxetine are not endowed with a rapid onset antianhedonic effect. On the other hand, clozapine treatment showed a motivational antianhedonic activity similar to that observed after lithium treatment. PMID:25686523

    2014-01-01

    Omalizumab is a monoclonal anti-immunoglobulin E antibody currently only approved for use in severe, refractory asthma. In recent years, many authors have reported satisfactory results with omalizumab in patients with difficult-to-treat chronic urticaria. As a result, clinical trials were undertaken to broaden the indication of omalizumab to include chronic urticaria, and the drug was recently cited as a third-line treatment after selective antihistamines at high doses in a consensus document on the treatment of chronic urticaria. In this article our aim is to provide a comprehensive update on the use of omalizumab in the treatment of chronic urticaria. The structure of this biologic agent and its possible mechanisms of actions in this setting will be presented. Treatment strategies and the different dosage regimens used in the series of cases published to date will also be reviewed. Finally, we will discuss the adverse effects that may arise with treatment and the recommended strategies for minimizing the most feared effect, anaphylaxis. Based on the experience of many researchers, omalizumab is emerging as a novel treatment for certain types of spontaneous refractory chronic urticaria and has shown promising results in this setting. The drug has a good safety profile and the main limitation is its high cost.

  18. Consumer access to clozapine in Australia: how does this compare to New Zealand and the United Kingdom?

    PubMed Central

    Mcmillan, Sara S.

    2016-01-01

    Background: Clozapine is an antipsychotic medication used in treatment resistant schizophrenia. However, clozapine is associated with a significant adverse effect profile and extensive monitoring is required to optimise consumer safety. Traditionally, clozapine can only be prescribed by a psychiatrist and dispensed at a hospital or hospital affiliated pharmacy in Australia. These restrictions could result in significant treatment burden for consumers taking clozapine. Objective: To identify (1) the different models of supply that exist for people living in the community taking clozapine in Australia and compare to those in New Zealand and the United Kingdom, and (2) explore how these supply models may impact on consumer burden from the perspective of professionals involved in the supply of clozapine. Method: Key informants were interviewed (n=8) from Australia, New Zealand and the United Kingdom regarding how consumers, who lived in the community, accessed clozapine. Data were analysed and led to the development of four clozapine supply models. These four models were further validated by an online survey of a wider sample (n=30). Data were analysed thematically and via simple descriptive statistics. Results: Clozapine supply varied depending on location. A secondary care model was utilised in the United Kingdom compared to a community based (primary care) model in New Zealand; Australia utilised a mixture of both secondary and primary care. A key theme from all study participants was that community pharmacy should be utilised to dispense clozapine to consumers living in the community, provided adequate training and safeguards are in place. It was noted that the utilisation of community pharmacies could improve access and flexibility, thereby reducing treatment burden for these consumers. Conclusion: There are predominately two models for supply of clozapine to consumers living in the community in Australia, New Zealand and the United Kingdom. One model utilises

A substantial number of patients stated that they had relief immediately following a series of four acupuncture treatments. It did not matter whether the needles were placed in the traditional meridian locations of in arbitrary fixed control points. Four weeks following treatment, 65% of the patients reported little or no reduction in the intensity of their pain, 17% reported a 50% reduction, and 18% at least a 75% reduction.

    Background Genetic testing in psychiatry promises to improve patient care through advances in personalised medicine. However, there are few clinically relevant examples. Aims To determine whether patients with a well-established genetic subtype of schizophrenia show a different response profile to the antipsychotic clozapine than those with idiopathic schizophrenia. Method We retrospectively studied the long-term safety and efficacy of clozapine in 40 adults with schizophrenia, half with a 22q11.2 deletion (22q11.2DS group) and half matched for age and clinical severity but molecularly confirmed to have no pathogenic copy number variant (idiopathic group). Results Both groups showed similar clinical improvement and significant reductions in hospitalisations, achieved at a lower median dose for those in the 22q11.2DS group. Most common side-effects were similarly prevalent between the two groups, however, half of the 22q11.2DS group experienced at least one rare serious adverse event compared with none of the idiopathic group. Many were successfully retried on clozapine. Conclusions Individuals with 22q11.2DS-schizophrenia respond as well to clozapine treatment as those with other forms of schizophrenia, but may represent a disproportionate number of those with serious adverse events, primarily seizures. Lower doses and prophylactic (for example anticonvulsant) management strategies can help ameliorate side-effect risks. This first systematic evaluation of antipsychotic response in a genetic subtype of schizophrenia provides a proof-of-principle for personalised medicine and supports the utility of clinical genetic testing in schizophrenia.

    Clozapine-induced sialorrhea (CIS) affects about one-third of patients treated with clozapine, at times can be stigmatizing, socially embarrassing, disabling, affect quality-of-life, cause poor compliance and can be potentially life-threatening adverse effect. Prompt and effective treatment of CIS may assist treatment tolerability, adherence, and better outcomes in patients with treatment nonresponsive schizophrenia. The beneficial effect of amisulpride augmentation of clozapine therapy for such patients may be enhanced by its anti-salivatory effect on CIS. Current series of five subjects who developed CIS that responded poorly to anticholinergic drugs found drastic improvement in daytime and nocturnal CIS with very low-dose (50-100 mg/day) of amisulpride. Low-dose amisulpride augmentation may also provide strong ameliorating effect on CIS. Nevertheless, a long-term, large-scale study with a broader dose range is warranted to evaluate the stability of this effect across time.

    The differential diagnosis for chronic ankle pain is quite broad. Ankle pain can be caused by intra-articular or extra-articular pathology and may be a result of a traumatic or nontraumatic event. A detailed patient history and physical examination, coupled with judicious selection of the appropriate imaging modalities, are vital in making an accurate diagnosis and providing effective treatment. Chronic ankle pain can affect all age groups, ranging from young athletes to elderly patients with degenerative joint and soft-tissue disorders. It has been estimated that 23,000 ankle sprains occur each day in the United States, representing approximately 1 sprain per 10,000 people per day. Because nearly one in five ankle injuries result in chronic symptoms, orthopaedic surgeons are likely to see patients with chronic ankle pain. Many patients with chronic ankle pain do not recall any history of trauma. Reviewing the management of the various disorders that can cause chronic ankle pain will help orthopaedic surgeons provide the best treatment for their patients. PMID:21553785

    Clozapine, an atypical antipsychotic agent, is highly effective in treatment-resistant schizophrenia; however, its major side effect is constipation. Instead of laxatives, rhein is a pharmacologically active component found in Rheum palmatum L., a medicinal herbal remedy for constipation. The purpose of this study is to determine whether rhein impacts the pharmacokinetics (PK) and pharmacodynamics (PD) of clozapine in brain when used to relieve clozapine-induced constipation. Here, we have investigated not only the PK of clozapine in blood but also the effects of rhein on the PK of clozapine in blood and in brain extracellular fluid together with the PD effects on neurotransmitters in extracellular fluid. The concentrations of clozapine and norclozapine in biologic samples were measured by ultra-performance liquid chromatography-tandem mass spectrometry. The drug-drug effects of rhein on extracellular neurotransmitter efflux in the rat medial prefrontal cortex (mPFC) produced by clozapine were assayed by high-performance liquid chromatography-electrochemical detection. The results demonstrate that the clozapine PK was nonlinear. Pretreatment with rhein for 7 days increased the total blood concentration of clozapine, but significantly reduced the unbound clozapine concentrations in the mPFC by approximately 3-fold. Furthermore, 7 days of rhein pretreatment thoroughly abolished the efflux of dopamine and its metabolite (3,4-dihydroxyphenylacetic acid) and altered the profile of homovanillic acid, another metabolite of dopamine, in the mPFC. In conclusion, rhein was found to substantially decrease clozapine and norclozapine concentrations in the mPFC dialysate, and this is accompanied by lower concentrations in the neurotransmitters in the same biophase. These findings suggest that a detailed clinical study for drug-drug interactions is recommended.

    We describe a case of a patient whose clozapine was discontinued after a “red result” following R-CHOP (rituximab with cyclophosphamide, hydroxydaunorubicin, Oncovin, and prednisolone) chemotherapy for large B-cell lymphoma. In some cases, manufacturers grant permission, on compassionate grounds, for clozapine to be continued or reinitiated following assessment by their consultant hematologist. Other than a recent case report, there is not much literature surrounding this medical issue. However, since the two leading causes of mortality in schizophrenia are cancer and cardiac disease, this is not an uncommon occurrence. Clinicians are reluctant to prescribe clozapine in view of its side-effect profile, despite its proven efficacy for managing treatment-resistant schizophrenia. The alternative is to prescribe two antipsychotics to manage symptoms. This approach may be associated with increased side effects, and evidence for actual benefits is scant. The consequences were disastrous in this case, as the individual not only relapsed following clozapine discontinuation, but the therapy for this treatable form of lymphoma had to be delayed. He was eventually admitted to an inpatient unit after having been stable for 15 years. We managed to stabilize him with olanzapine and aripiprazole which enabled the heme-oncology group to resume R-CHOP therapy with filgrastim (granulocyte colony-stimulating factor). Even so, he continued to exhibit severe psychotic symptoms, with religious delusions and auditory hallucinations. We therefore applied for permission to rechallenge him on clozapine. Permission was granted when protocol conditions were met, and reinitiation went without any adverse events. The patient’s symptoms showed improvement within a few weeks, and the other antipsychotics were discontinued once clozapine was titrated up to 300 mg. The decision to reinitiate clozapine following a red result is not to be taken lightly, but needs to be considered in terms of

    Chronic spontaneous urticaria, also known as chronic idiopathic urticaria or simply chronic urticaria, is a common disorder that has a prevalence in the general population that ranges between 0.5% and 1%. This condition negatively affects the patient's quality of life and has considerable impact on direct and indirect health-related costs. Chronic urticaria is difficult to manage. Nonsedating H1 antihistamines are the first line of therapy, but fewer than 50% of patients experience relief at recommended dosages. Although guidelines call for increasing the dosage when response is inadequate, some patients still do not achieve adequate control of symptoms. New treatment alternatives, with proven efficacy under the standards of evidence-based medical practice, must therefore be developed.

    Background Patients with schizophrenia often suffer from cognitive deficits and negative symptoms that are poorly responsive to antipsychotics including clozapine. Clozapine-induced sedation can worsen cognition and impair social and occupational functioning. Objectives To evaluate the efficacy, tolerability, and safety of modafinil for negative symptoms, cognition, and wakefulness/fatigue in DSM-IV–diagnosed schizophrenia patients treated with clozapine. Method A double-blind, placebo-controlled, flexible-dosed 8-week pilot trial was conducted between September 2003 and September 2007, adding modafinil up to 300 mg/d to stabilized schizophrenia outpatients receiving clozapine. Psychopathology, cognition, and wakefulness/fatigue were assessed with standard rating scales. Results Thirty-five patients were randomly assigned to treatment with study drug and included in the analysis. Modafinil did not reduce negative symptoms or wakefulness/fatigue or improve cognition compared to placebo. Modafinil was well tolerated and did not worsen psychosis. Conclusions Results of this pilot trial do not support routine use of modafinil to treat negative symptoms, cognitive deficits, or wakefulness/fatigue in patients on clozapine. However, given our limited power to detect a treatment effect and the clear possibility of a type II error, larger trials are needed to resolve or refute a potential therapeutic effect of uncertain magnitude.

    Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition among men of a wide age range, with detrimental effects on quality of life. The etiology, pathogenesis, and optimal treatment of CP/CPPS remain unknown, although progress has been made in these domains in recent years. A wide variety of pharmacologic and nonpharmacologic therapies have been studied in clinical trials, but most have shown limited efficacy in symptom alleviation. CP/CPPS is increasingly viewed as a condition that involves variable degrees of neuropathic pain. Medications such as gabapentin, pregabalin, memantine, and tricyclic antidepressants are often used in other neuropathic pain conditions and, therefore, are considered potential treatments for CP/CPPS. Few studies of these agents in patients with CP/CPPS have been reported, but future clinical trials should help to determine their utility and to characterize the pathogenetic mechanisms of pain in CP/CPPS. Combining treatment trials with biomarker, genomic, and imaging studies, in addition to epidemiologic and symptom-based assessments, will maximize the ability to probe disease etiology and pathogenesis, as well as identify effective treatment.

New technique including ligation of mucosa and submucosa of low-ampullar rectum providing ligation of hemorrhoidalvessels, lifting and recto-anal repair is developed and suggested. This method is advisable to use in case of chronic internal hemorrhoids stages I and II. The authors recommend simultaneous combined ligation of mucosa of low-ampullar rectum and internal hemorrhoids for stages III and IV. Different variants of latex ligation with external hemorrhoids excision were used in 103 patients. Pointed variants of latex ligation preserve important advantages including mini-invasiveness, simplicity and wide availability, low cost. Good remote results were obtained after these procedures in 87.3% of observations. Suggested tactics extends use of latex ligation and increases its effectiveness in treatment of different stages and forms of chronic hemorrhoids.

    There are many reports that show different thyroid abnormalities in schizophrenia without clear establishment of their role in etiology and treatment outcome of schizophrenia. Among these reports, there are only a few that consider a role for thyroid hormones as augmenting agents in the treatment with antipsychotic drugs. This case report outlines symptom subsidence of a patient with clozapine refractory paranoid schizophrenia and normal thyroid function who added levothyroxine to clozapine and found that symptoms of psychosis returned once levothyroxine was discontinued. Although this observation needs to be confirmed in controlled clinical trials, we aimed to discuss possible hypothesized mechanisms underlying this observation. PMID:26078905

    There have been limited reports on the effect of the atypical anti-psychotic agent clozapine on sleep measures and hormone secretion. The goal of this study was to determine the type, rate, and extent of changes in sleep measures and nighttime secretion of growth hormone (GH) and cortisol during clozapine treatment. Five schizophrenic patients (age: 32.4+/-7.4) and five age- and sex-matched normal subjects (age: 33.0+/-5.1) underwent nocturnal polysomnography (NPSG) before clozapine therapy (S1), and during early and late clozapine therapy (S2 and S3). Serum GH and cortisol levels were monitored during each NPSG. NPSG findings showed that the mean total sleep time, sleep efficiency, and duration of awakening were increased at S2, and maintained until S3. The mean amounts of stage 2 sleep at S2 and S3 increased significantly compared with that of S1. In unmedicated schizophrenic patients, the mean plasma GH level in rapid eye movement sleep was lower than during the waking stage, and the mean level of plasma cortisol was higher during the waking stage. Plasma cortisol levels did not differ between control subjects and patients at any time, but clozapine treatment decreased plasma cortisol levels at S2 compared with S1 and S3. Plasma GH levels were unchanged by clozapine treatment. Clozapine improved sleep continuity and increased stage 2 sleep time from the beginning of therapy. These effects were maintained through at least 7 weeks of therapy. However, clozapine did not affect the relationship of plasma GH and cortisol levels with sleep stages in schizophrenic patients.

    This paper reviews the impact of genetic variability of drug metabolizing enzymes, transporters, receptors, and pathways involved in chronic pain perception on the efficacy and safety of analgesics and other drugs used for chronic pain treatment. Several candidate genes have been identified in the literature, while there is usually only limited clinical evidence substantiating for the penetration of the testing for these candidate biomarkers into the clinical practice. Further, the pain-perception regulation and modulation are still not fully understood, and thus more complex knowledge of genetic and epigenetic background for analgesia will be needed prior to the clinical use of the candidate genetic biomarkers.

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a sporadically occurring, acquired neuropathic condition of autoimmune origin with chronic progressive or relapsing-remitting disease course. CIDP is a treatable disorder; a variety of immunosuppressive and immunomodulatory agents are available to modify, impede, and even reverse the neurological deficits and sequelae that manifest in the course of the disease. However, in many cases CIDP is not curable. Challenges that remain in the treatment of CIDP patients are well recognized and include a remarkably individual heterogeneity in terms of disease course and treatment response as well as a lack of objective and feasible measures to predict and monitor the responsiveness to the available therapies. In this chapter an overview of the currently used drugs in the treatment of CIDP patients is given and some important and controversial issues that arise in the context of care for CIDP patients are discussed.

    Chronic myelogenous leukemia is a clonal myeloproliferative neoplasm caused by reciprocal translocation involving chromosomes 9 and 22 resulting in the expression of a constitutively activated BCR-ABL1 tyrosine kinase that leads to the malignant transformation of the hematopoietic stem cells. The condition was previously known as a relentlessly progressive disease, but the treatment was revolutionalized by the efficacy of tyrosine kinase inhibitors. Therapeutic success is thus currently determined by the depth of molecular response achieved on therapy. Multiple tyrosine kinase agents are available even for the first line treatment. This guideline summarizes current focal points of the treatment of chronic myelogenous leukemia specific to Hungary and provides definitions for optimal molecular responses in this condition. Orv.

    A method for therapy of chronic parenchymatous parotitis is suggested supplementing dimethyl sulfoxide. As reported, the parotid glands produce parotin, an insulin-like substance, whose production is reduced in chronic parotitis; hence, short-acting insulin administered in microdoses was chosen for therapy. To potentiate local insulin effect and increase the sensitivity of oral mucosa peripheral receptors to it a 5% calcium pantothenate solution was used. This method was used in the treatment of 42 patients with chronic parenchymatous parotitis aged 23 to 62. The method is effective, it can be easily used by the patients themselves, and there are virtually no contraindications against such therapy.

    It has been repeatedly shown that clozapine is more efficacious than other antipsychotics in the management of treatment-resistant schizophrenia. However, clozapine is associated with a number of side effects including weight gain. Antipsychotic-induced weight gain has been linked with a number of untoward events including psychological factors such as stigma and low self-esteem, and physical factors such as metabolic syndromes and untimely death. The mechanism underlying antipsychotic (including clozapine)-induced weight gain is not clearly understood, although it is said to involve several brain areas, several neurotransmitters, neuropeptides and genetic factors. To some individuals however, clozapine use is associated with significant weight loss (13.5–50% of body weight). The observed weight loss in these groups of patients has not been attributed to any underlying diagnosable physical disorders. There have been a handful cases published with this phenomenon, which seems to be contrary to what is expected when clozapine is prescribed. From the currently published cases three groups emerge – those who lost weight simply by taking clozapine, those who lost weight due to improved mental state, engaging in diet and increased exercise, and those for whom weight loss was a sign of a poor response to clozapine. A case of JX who has a diagnosis of schizoaffective disorder is presented. JX lost over 26% of her body weight when she was prescribed clozapine. A detailed review of other published cases is undertaken. The underlying mechanisms involving weight loss are discussed and the implications to clinicians are highlighted. Coordinated studies to examine these groups of patients may provide some insight, not only in the mechanism of clozapine-induced weight loss, but also in the better management of patients with treatment-resistant schizophrenia involving clozapine use.

    Background Although clozapine is the gold-standard for treatment refractory schizophrenia, it has the worst metabolic profile of all antipsychotics. This is partly mediated by clozapine’s impact on glucagon-like peptide (GLP-1). There is an absence of robust evidence for effective treatments for clozapine associated weight gain and metabolic syndrome. Metformin, with its role in increasing GLP-1 may aid weight loss among people on clozapine. Methods We conducted a systematic-review and meta-analysis of metformin versus placebo for change in weight and metabolic syndrome for people on clozapine without diabetes mellitus. We searched the Cochrane Schizophrenia Group’s trial register, Pubmed and Embase, as well as the following Chinese databases: the Chinese Biomedical Literature Service System and China Knowledge Resource Integrated Database. This was supplemented by hand searches of key papers. Results Eight studies, of which three were from Chinese databases, with 478 participants were included. We found that metformin was superior to placebo in terms of weight loss (-3.12kg, 95%CI -4.88kg to -1.37kg) and BMI (-1.18kg/m2, 95%CI -1.76kg/m2 to -0.61kg/m2). Metformin significantly improved three of the five components of metabolic syndrome; waist circumference, fasting glucose and triglycerides. Sensitivity analysis on study quality and duration did not greatly impact results. Conclusions Metformin led to clinically meaningful weight loss among people on clozapine, and may reduce the rates of metabolic syndrome. Inclusion of metformin into the treatment protocols of people on clozapine, as tolerated, should be considered. Trial Registration PROSPERO registration number: CRD42015029723 PMID:27304831

    Although acute pain is a physiological response warning the human body of possible harm, chronic pain can be a pathological state associated with various diseases or a disease in itself. In the United States alone, around one-third of the population has experienced a chronic pain condition and annual cost to the society is in the range of 500-600 billion dollars.(1) It should be noted that if at all this is a very modest estimate, it surpasses the costs associated with cancer, heart disease, and diabetes combined.(1) Unfortunately, despite these humongous costs, the treatment of chronic pain is inadequate.(1) Chronic pain affects individuals in a variety of forms, and below we highlight some of the most common chronic pain conditions seen in a pain clinic. Most of these disorders are difficult to treat and typically require multimodal therapy including pharmacotherapy, behavioral modification, and targeted interventions. We have summarized the scope of each disorder, clinical features, proposed mechanisms, and current therapies for them (Table 1).

    Chronic hepatitis C is a leading cause of liver-related morbidity and mortality worldwide. If untreated, chronic hepatitis C can progress to advanced liver fibrosis, cirrhosis, liver failure, hepatocellular carcinoma and death. Until recently, treatment of hepatitis C predominantly constituted an immunomodulatory agent, peg-interferon-alfa and ribavirin. In 2011, the first class of directly acting antiviral agents, HCV NS3/4A serine protease inhibitors, was added to peg-interferon-alfa and ribavirin with increased efficacy. In the past year, an NS5B inhibitor, sofosbuvir, has emerged as a potent agent with pangenotypic efficacy, resulting in the first interferon-free regimen for the treatment of hepatitis C. This review summarizes the data that resulted in regulatory approval of sofosbuvir and highlights the future of hepatitis C therapy with sofosbuvir as the backbone of a highly effective antiviral regimen.

    Refractory schizophrenia poses many therapeutic dilemmas. Clozapine is currently considered as the most effective medication for the treatment of refractory schizophrenia. Unfortunately, it carries serious and often life-threatening adverse effects such as agranulocitosis, hypersalivation, somnolence, weight gain, diabetes, and epileptic seizures. Various combinations of clozapine with typical and other atypical antipsychotics have been suggested to improve its efficacy and reduce its often dose-related adverse effects. We present a case of a 37-year-old patient with refractory schizophrenia who has responded well to the combination of clozapine, sodium valproate, and pipamperone. The improvement was more evident in the following symptoms: auditory hallucinations, delusions, formal thought disorder, anhedonia, and social withdrawal. The combination was well tolerated: No extrapyramidal adverse effects were noted and the patient's full blood count was within normal limits. Pipamperone, a butyrophenone derivative, is a more selective antagonist of dopaminergic D4 receptors compared with D2 receptors and a serotoninergic 5HT-2A receptors antagonist. Thus, it shows "atypicality" and shares common characteristics with clozapine: 5HT-2A antagonism and D4 > D2 blockade selectivity. Therefore, augmentation of clozapine with pipamperone theoretically should have a synergistic effect that may provide several benefits to the patient: better antipsychotic efficacy with low risk for extrapyramidal adverse effects. This combination may also allow a decrease in clozapine dose, limiting its challenging adverse effects. To the author's knowledge, successful treatment of refractory schizophrenia with this drug combination is reported for the first time in the literature and probably merits further research.

    Significance: Chronic wounds include, but are not limited, to diabetic foot ulcers, venous leg ulcers, and pressure ulcers. They are a challenge to wound care professionals and consume a great deal of healthcare resources around the globe. This review discusses the pathophysiology of complex chronic wounds and the means and modalities currently available to achieve healing in such patients. Recent Advances: Although often difficult to treat, an understanding of the underlying pathophysiology and specific attention toward managing these perturbations can often lead to successful healing. Critical Issues: Overcoming the factors that contribute to delayed healing are key components of a comprehensive approach to wound care and present the primary challenges to the treatment of chronic wounds. When wounds fail to achieve sufficient healing after 4 weeks of standard care, reassessment of underlying pathology and consideration of the need for advanced therapeutic agents should be undertaken. However, selection of an appropriate therapy is often not evidence based. Future Directions: Basic tenets of care need to be routinely followed, and a systematic evaluation of patients and their wounds will also facilitate appropriate care. Underlying pathologies, which result in the failure of these wounds to heal, differ among various types of chronic wounds. A better understanding of the differences between various types of chronic wounds at the molecular and cellular levels should improve our treatment approaches, leading to better healing rates, and facilitate the development of new more effective therapies. More evidence for the efficacy of current and future advanced wound therapies is required for their appropriate use. PMID:26339534

Evidence for short-term use of systemic corticosteroids has been shown to be favorable in CRSwNP, but still limited in CRSsNP. Topical corticosteroids improve symptom scores in both CRS subgroups. The role of microbes in CRS is still controversial. Culture-directed antibiotics are recommended for CRSsNP with exacerbation. Long-term use of low dosage antibiotics is recommended for CRSsNP for their anti-inflammatory effects. Other emerging treatment options are also discussed. PMID:23785241

    Chronic lymphocytic leukemia (CLL) is the most common leukemia in the Western countries. The abnormal B lymphocytes progress into the blood and infiltrate the bone marrow, liver, spleen and lymph nodes. CLL is a disease of the adults and older individuals who often have coexisting conditions. It usually progresses slowly, but in patients who need treatment, CLL eventually returns. For relapsed, refractory patients treatment options are limited. The only curative treatment is bone marrow transplantation. However, the new, alternative therapeutics show superior efficacy in CLL than standard regimens. The aim of this review is to summarize the most important therapeutic aspects of CLL and to give an insight into the novel treatment options. PMID:27275639

    Chronic fatigue syndrome is characterised by intense fatigue, with duration of over six months and associated to other related symptoms. The latter include asthenia and easily induced tiredness that is not recovered after a night's sleep. The fatigue becomes so severe that it forces a 50% reduction in daily activities. Given its unknown aetiology, different hypotheses have been considered to explain the origin of the condition (from immunological disorders to the presence of post-traumatic oxidative stress), although there are no conclusive diagnostic tests. Diagnosis is established through the exclusion of other diseases causing fatigue. This syndrome is rare in childhood and adolescence, although the fatigue symptom per se is quite common in paediatric patients. Currently, no curative treatment exists for patients with chronic fatigue syndrome. The therapeutic approach to this syndrome requires a combination of different therapeutic modalities. The specific characteristics of the symptomatology of patients with chronic fatigue require a rapid adaptation of the educational, healthcare and social systems to prevent the problems derived from current systems. Such patients require multidisciplinary management due to the multiple and different issues affecting them. This document was realized by one of the Interdisciplinary Work Groups from the Institute for Rare Diseases, and its aim is to point out the main social and care needs for people affected with Chronic Fatigue Syndrome. For this, it includes not only the view of representatives for different scientific societies, but also the patient associations view, because they know the true history of their social and sanitary needs. In an interdisciplinary approach, this work also reviews the principal scientific, medical, socio-sanitary and psychological aspects of Chronic Fatigue Syndrome.

    Interdisciplinary concepts for the treatment of chronic wounds are mandatory because of the multifactorial reasons causing ulceration. This is a report on 6 years' experience at the wound care unit in Tübingen. Patients with chronic wounds (mainly diabetic, venous, and ischemic ulcers) were treated primarily as outpatients according to a standardised and interdisciplinary wound care protocol. Quality control was guaranteed by a standardised wound documentation system. The evaluation of this data demonstrates an overall healing rate of 69% within 52 weeks (mean). Before patients were referred to Tübingen, unsuccessful therapy was characterised by a mean wound duration of 35 weeks. The results presented justify this interdisciplinary wound care unit.

    Chronic low back pain (CLBP) is a significant healthcare problem, and many individuals with CLBP remain unresponsive to available interventions. Previous research suggests that hypnosis is effective for many chronic pain conditions; however, data to support its efficacy for CLBP are outdated and have been limited primarily to case studies. This pilot study indicated that a brief, 4-session standardized self-hypnosis protocol, combined with psycho-education, significantly and substantially reduced pain intensity and pain interference. Significant session-to-session improvements were also noted on pain ratings and mood states; however, follow-up data suggest that these benefits may not have been maintained across time in this sample. These findings need to be replicated and confirmed in a larger clinical trial, which could also assess the long-term effects of this treatment. PMID:20183738

    The first treatment of chronic myeloid leukemia (CML) included spleen x-radiation and conventional drugs, mainly Busulfan and Hydroxyurea. This therapy improved the quality of life during the chronic phase of the disease, without preventing nor significantly delaying the progression towards advanced phases. The introduction of allogeneic stem cell transplantation (alloSCT) marked the first important breakthrough in the evolution of CML treatment, because about 50% of the eligible patients were cured. The second breakthrough was the introduction of human recombinant interferon-alfa, able to achieve a complete cytogenetic remission in 15% to 30% of patients, with a significant survival advantage over conventional chemotherapy. At the end of the last century, about 15 years ago, all these treatments were quickly replaced by a class of small molecules targeting the tyrosine kinases (TK), which were able to induce a major molecular remission in most of the patients, without remarkable side effects, and a very prolonged life-span. The first approved TK inhibitor (TKI) was Imatinib Mesylate (Glivec or Gleevec, Novartis). Rapidly, other TKIs were developed tested and commercialized, namely Dasatinib (Sprycel, Bristol-Myers Squibb), Nilotinib (Tasigna, Novartis), Bosutinib (Busulif, Pfizer) and Ponatinib (Iclusig, Ariad). Not all these compounds are available worldwide; some of them are approved only for second line treatment, and the high prices are a problem that can limit their use. A frequent update of treatment recommendations is necessary. The current treatment goals include not only the prevention of the transformation to the advanced phases and the prolongation of survival, but also a length of survival and of a quality of life comparable to that of non-leukemic individuals. In some patient the next ambitious step is to move towards a treatment-free remission. The CML therapy, the role of alloSCT and the promising experimental strategies are reviewed in the context

    The treatment of chronic lymphocytic leukemia (CLL) has evolved over the last few decades. Recognition has increased of several key components of CLL biology currently manipulated for therapeutics. A milestone in the treatment of CLL was reached with the incorporation of immunotherapy with conventional chemotherapy. The fludarabine/cyclophosphamide/rituximab combination has demonstrated survival advantage for the first time in the treatment of CLL. Several other biological compounds are being explored with the hope of improving responses, impacting survival, and ultimately curing CLL. Important agents being tested are targeted on CLL surface molecules and their ligands, signal transduction protein and oncogenes. This review provides a brief summary of the recent advances made in preclinical and clinical investigation of selected promising therapeutic agents, which lead the target-directed therapeutic approach.

    Urticaria is a common and often debilitating dermatological condition defined by the sudden appearance of wheals, angioedema or both. It is further classified into specific subtypes based on duration and specific triggers. Awareness and understanding of urticaria are important to ensure a correct initial diagnosis and initiate appropriate guideline-based treatment outlining a stepwise approach. However, in chronic urticaria, approximately 50% of patients are refractory to the first step, the use of licensed doses of second-generation H1-antihistamines. If the second step, an increase in the dose of the second-generation H1-antihistamines, is also not successful, in the third step omalizumab (Xolair™, Novartis Pharma AG(©)/Genentech, Inc.(©)), an anti-IgE therapy, is recommended as an add-on. Of all alternative treatments mentioned in the guidelines, omalizumab is currently the only licensed treatment for H1-antihistamine-refractory chronic spontaneous urticaria, has a favorable risk/benefit ratio and was well tolerated in clinical studies.

    Chronic fatigue syndrome (CFS) presents with fatigue, low motivation, diminished mood, and reduced activity, all symptoms having extensive diagnostic overlaps with depression. Studies have linked chronic viral infections with CFS, and antiviral therapy has effectively treated CFS in adult patients. In a retrospective case series, 15 adolescents and preteens referred to the author for treatment-resistant depression or mood disorder were evaluated and found to have met the Fukuda diagnostic criteria for CFS. While a subset (4/15) had been diagnosed in the past with CFS, the majority had a current diagnosis of depression or a mood disorder. The Diagnostic and Statistical Manual-IV Text Revision (DSM-IV TR) criteria for depression were not met in all patients, although 3 cases of mood disorder not otherwise specified (MD-NOS) and 1 case of Tourette syndrome (TS) plus MD-NOS were diagnosed. Baseline scores on the Children's Depression Inventory (CDI) were below the cutoff for depression in all but 1 patient. Baseline self-assessment scales for CFS or fatigue were obtained and sleep was evaluated with sleep logs. All patients were treated subsequently with valacyclovir, with 93% having a positive response. At the end of treatment, scores on fatigue self-assessment scales improved significantly (P < .001). Vigor subscale scores also improved significantly (P < .001). Some patients experienced complete resolution of symptoms. Although not every patient was tested, available laboratory testing revealed increased counts of natural killer (NK) cells and decreased human herpesvirus 6 (HHV-6) antibody titers in all patients who responded to valacyclovir. This article discusses the significance of infectious agents in the pathogenesis of psychiatric symptoms. The study's data support an intriguing hypothesis that a portion of treatment-resistant depression in fact may be undiagnosed CFS or other chronic viral infection.

    For inflammatory bowel disease, unlike other chronic illnesses, there are sparse data available about patients' adherence to medication. The few studies vary widely, but noncompliance rates tend to be high, about 30-40%. Psychiatric disorders, including depression and anxiety, and poor patient-physician relationships are the most common causes of these patients' lack of adherence. Failure to adhere to prescribed medications increases risk of relapse and of colorectal cancer. Strategies that can improve adherence include establishing a partnership with the patient, simplifying the treatment regimen and increasing awareness through education and feedback.

    The atypical antipsychotic drug clozapine remains one of most effective treatments for schizophrenia, given a lack of extrapyramidal side effects, improvements in negative symptoms, cognitive impairment, and in symptoms in treatment-resistant schizophrenia. The adverse effects of clozapine, including agranulocytosis, make finding a safe clozapine-like a drug a goal for drug developers. The drug discrimination paradigm is a model of interoceptive stimulus that has been used in an effort to screen experimental drugs for clozapine-like atypical antipsychotic effects. The present study was conducted to elucidate the receptor-mediated stimulus properties that form this clozapine discriminative cue by testing selective receptor ligands in rats trained to discriminate a 1.25mg/kg dose of clozapine from vehicle in a two choice drug discrimination task. Full substitution occurred with the 5-HT2A inverse agonist M100907 and the two preferential D4/5-HT2/α1 receptor antagonists Lu 37-114 ((S)-1-(3-(2-(4-(1H-indol-5-yl)piperazin-1-yl)ethyl)indolin-1-yl)ethan-1-one) and Lu 37-254 (1-(3-(4-(1H-indol-5-yl)piperazin-1-yl)propyl)-3,4-dihydroquinolin-2(1H)-one). Partial substitution occurred with the D4 receptor antagonist Lu 38-012 and the α1 adrenoceptor antagonist prazosin. Drugs selective for 5-HT2C, 5-HT6 muscarinic, histamine H1, and benzodiazepine receptors did not substitute for clozapine. The present findings suggest that 5-HT2A inverse agonism and D4 receptor antagonism mediate the discriminative stimulus properties of 1.25mg/kg clozapine in rats, and further confirm that clozapine produces a complex compound discriminative stimulus.

    Objective It is well documented that clozapine treatment causes agranulocytosis, but it can also induce drowsiness, constipation, and hypersalivation; however, these symptoms are usually less severe. It has been reported that clozapine-treated patients with schizophrenia and psychiatric healthcare professionals consider different side effects to be important. The aim of this study was to assess current practice related to the side effects of clozapine in clozapine-treated patients with schizophrenia and psychiatric healthcare professionals in Japan. Methods Data were collected from January 2014 to August 2015 in Okehazama Hospital, Kakamigahara Hospital, and Numazu Chuo Hospital. Clozapine-treated patients with schizophrenia and psychiatric healthcare professionals (psychiatrists and pharmacists) were enrolled in this study. Results Of the 106 patients and 120 psychiatric healthcare professionals screened, 100 patients and 104 healthcare professionals were included in this study. We asked the patients what side effects caused them trouble and we asked psychiatric healthcare professionals what side effects caused them concern. The patients and psychiatrists held similarly positive views regarding the efficacy of clozapine. The healthcare professionals were concerned about agranulocytosis (92.4%), blood routines (61.3%). On the other hand, the patients experienced hypersalivation (76.0%), sleepiness (51.0%). A positive correlation (R=0.696) was found between patient satisfaction and DAI-10 score. Conclusion Patients experienced more problems than healthcare professionals expected. However, usage experience of clozapine healthcare professionals tended to have similar results to patients. It is necessary that all healthcare professionals fully understand the efficacy and potential side effects of clozapine. This is very important for promoting clozapine treatment in Japan.

    Accumulating evidence suggests an association between patient pretreatment expectations and numerous health outcomes. However, it remains unclear if and how expectations relate to outcomes after treatments in multidisciplinary pain programs. The present study aims at investigating the predictive association between expectations and clinical outcomes in a large database of chronic pain patients. In this observational cohort study, participants were 2272 patients treated in one of 3 university-affiliated multidisciplinary pain treatment centers. All patients received personalized care, including medical, psychological, and/or physical interventions. Patient expectations regarding pain relief and improvements in quality of life and functioning were measured before the first visit to the pain centers and served as predictor variables. Changes in pain intensity, depressive symptoms, pain interference, and tendency to catastrophize, as well as satisfaction with pain treatment and global impressions of change at 6-month follow-up, were considered as treatment outcomes. Structural equation modeling analyses showed significant positive relationships between expectations and most clinical outcomes, and this association was largely mediated by patients' global impressions of change. Similar patterns of relationships between variables were also observed in various subgroups of patients based on sex, age, pain duration, and pain classification. Such results emphasize the relevance of patient expectations as a determinant of outcomes in multimodal pain treatment programs. Furthermore, the results suggest that superior clinical outcomes are observed in individuals who expect high positive outcomes as a result of treatment.

    Over the past decade, several targeted therapies (e.g. imatinib, dasatinib, nilotinib) have been developed to treat Chronic Myeloid Leukemia (CML). Despite an initial response to therapy, drug resistance remains a problem for some CML patients. Recent studies have shown that resistance mutations that preexist treatment can be detected in a substantial number of patients, and that this may be associated with eventual treatment failure. One proposed method to extend treatment efficacy is to use a combination of multiple targeted therapies. However, the design of such combination therapies (timing, sequence, etc.) remains an open challenge. In this work we mathematically model the dynamics of CML response to combination therapy and analyze the impact of combination treatment schedules on treatment efficacy in patients with preexisting resistance. We then propose an optimization problem to find the best schedule of multiple therapies based on the evolution of CML according to our ordinary differential equation model. This resulting optimization problem is nontrivial due to the presence of ordinary different equation constraints and integer variables. Our model also incorporates drug toxicity constraints by tracking the dynamics of patient neutrophil counts in response to therapy. We determine optimal combination strategies that maximize time until treatment failure on hypothetical patients, using parameters estimated from clinical data in the literature. PMID:27764087

    Clozapine and some other atypical antipsychotics (e.g. quetiapine, olanzapine) have been found to exert a characteristic profile of action on operant behaviour maintained by progressive-ratio schedules, as revealed by Killeen's Mathematical Principles of Reinforcement model of schedule-controlled behaviour. These drugs increase the value of a parameter that expresses the 'incentive value' of the reinforcer (a) and a parameter that is inversely related to the organism's 'motor capacity' (δ). This experiment examined the effects of two further atypical antipsychotics, aripiprazole and amisulpride, on progressive-ratio schedule performance in rats; the effects of clozapine and a conventional antipsychotic, haloperidol, were also examined. In agreement with previous findings, clozapine (4, 8 mg kg⁻¹) increased a and δ, whereas haloperidol (0.05, 0.1 mg kg⁻¹) reduced a and increased δ. Aripiprazole (3,30 mg kg⁻¹) increased δ but did not affect a. Amisulpride (5, 50 mg kg⁻¹) had a delayed and protracted effect: δ was increased 3-6 hours after treatment; a was increased 1.5 hours, and reduced 12-24 hours after treatment. Interpretation based on Killeen's model suggests that aripiprazole does not share clozapine's ability to enhance reinforcer value. Amisulpride produced a short-lived enhancement, followed by a long-lasting reduction, of reinforcer value. Both drugs impaired motor performance.

    Chronic thromboembolic pulmonary hypertension is a rare but underdiagnosed disease. The development of imaging played a crucial role for the screening and the decision of operability over the past few years. Indeed, chronic thromboembolic pulmonary hypertension is the only type of pulmonary hypertension with a potential curative treatment: pulmonary endarterectomy. It is a complexe surgical procedure performed under cardiopulmonary bypass with deep hypothermia and circulatory arrest. The aim of the procedure is to completely remove the scar tissue inside the pulmonary arteries down to the segmental and sub-segmental levels. Compared to lung transplantation, which carries a postoperative mortality of 15-20% and a 5-year survival of 50%, pulmonary endarterectomy is a curative treatment with a postoperative mortality of less than 3%. However, lung transplantation remains an option for young patients with inoperable distal disease or after pulmonary endarterectomy failure. Considering that medical history of deep venous thrombosis or pulmonary embolism is lacking in 25 to 50%, the diagnosis of chronic thromboembolic pulmonary hypertension remains challenging. The lung V/Q scan is useful for the diagnosis showing ventilation and perfusion mismatches. Lesions located at the level of the pulmonary artery, the lobar or segmental arteries may be accessible to surgical removal. The pulmonary angiogram with the lateral view and the pulmonary CT scan help to determine the level of the intravascular lesions. If there is a correlation between the vascular obstruction assessed by imaging and the pulmonary resistance, pulmonary endarterectomy carries a postoperative mortality of less than 3% and has a high rate of success. If the surgery is performed at a later stage of the disease, pulmonary arteriolitis developed mainly in unobstructed territories and participated in the elevated vascular resistance. At this stage, postoperative risk is higher. PMID:25154908

    Chronic rhinosinusitis (CRS) is difficult to define, partly because the disease recognized by clinicians is both heterogeneous and the endpoint of different pathophysiologic, genetic, and environmental interactions. For this article, we define CRS as symptoms lasting more than 3 months combined with an imaging study showing inflammation in the sinuses. This article comments on some factors that are believed to influence the expression of CRS. These factors include anatomic abnormalities, immotile cilia, age, allergic sensitization, immune deficiency, dental infections, gastrointestinal reflux, smoking, biofilm, and the microbiome. Other factors are discussed in other sections. The article concludes with an overview of treatment. In brief, nasal steroids and large volume nasal irrigations are the first line of treatment for this inflammatory disease. Antibiotics are used when infections are thought to contribute. Oral steroids are frequently used in severe disease. Endoscopy and sinus computed tomography scans are used when surgery is contemplated. PMID:27393776

    None of the drugs currently available for chronic obstructive pulmonary disease (COPD) are able to reduce the progressive decline in lung function which is the hallmark of this disease. Smoking cessation is the only intervention that has proved effective. The current pharmacological treatment of COPD is symptomatic and is mainly based on bronchodilators, such as selective β2-adrenergic agonists (short- and long-acting), anticholinergics, theophylline, or a combination of these drugs. Glucocorticoids are not generally recommended for patients with stable mild to moderate COPD due to their lack of efficacy, side effects, and high costs. However, glucocorticoids are recommended for severe COPD and frequent exacerbations of COPD. New pharmacological strategies for COPD need to be developed because the current treatment is inadequate.

    This literature review is focused on diagnostics of acute clozapine intoxication with the fatal outcome. According to the Russian authors, clozapine intoxication ranks first in the structure of criminal poisoning and accounted for 99.7% of all the cases that occurred in Moscow during the period from 2003 to 2006. Toximetric investigations of clinical manifestations of clozapine intoxication revealed that the threshold clozapine concentration in blood is 0.12 ± 0.06 mg/I, the critical and lethal concentrations are 1.01 ± 0.2 mg/I and 3.5 ± 1.5 mg/I respectively. Autopsy on corpses of the victims of clozapine intoxication showed that most clozapine-induced pathological changes have a non-specific character (including largely circulatory disorders and dystrophic changes in parenchymatous organs). Clozapine poisoning is associated with the lengthening of QT-interval on ECG; at the values in excess of 500 ms, the risk of severe arrhythmia and sudden death significantly increases. Clozapine intake may lead to the development of potentially fatal myocarditis (the so-called clozapine-associated eosinophilic myocardium) in somatically healthy subjects. Foreign researchers report the possibility of a post-mortem increase of blood clozapine content compared with its antemortem level. They also showed that simultaneous use of substances stimulating activity of cytochrome P-450 enzymes (ethyl alcohol, finlepsin, fenitrin, nicotine) and clozapine accelerates metabolism and thereby reduces clozapine concentration in blood. It is concluded that comprehensive investigations of clozapine intoxication are needed taking into consideration pathomorphological changes induced by this agent, its potential interaction with other factors influencing human body, and the results of forensic chemical expertise of the fatal cases.

    Objective To report the clinical and functional results from arthroscopic release of the short radial extensor of the carpus (SREC) in patients with chronic lateral epicondylitis that was refractory to conservative treatment. Methods Over the period from January 2012 to November 2013, 15 patients underwent arthroscopic treatment. The surgical technique used was the one described by Romeo and Cohen, based on anatomical studies on cadavers. The inclusion criteria were that the patients needed to present lateral epicondylitis and that conservative treatment (analgesics, anti-inflammatory agents, corticoid infiltration or physiotherapy) had failed over a period of more than six months. The patients were evaluated based on the elbow functional score of the Mayo Clinic, Nirschl's staging system and a visual analog scale (VAS) for pain. Results A total of 15 patients (9 men and 6 women) were included. The mean Mayo elbow functional score after the operation was 95 (ranging from 90 to 100). The pain VAS improved from a mean of 9.2 before the operation to 0.64 after the operation. On Nirschl's scale, the patients presented an improvement from a mean of 6.5 before the operation to approximately one. There were significant differences from before to after the surgery for the three functional scores used (p < 0.01). No correlations were observed using the Spearman test between the results and age, gender, length of time with symptoms before the operation or injury mechanism (p > 0.05). Conclusion Arthroscopic treatment for lateral epicondylitis was shown to be a safe and effective therapeutic option when appropriately indicated and performed, in refractory cases of chronic lateral epicondylitis. It also allowed excellent viewing of the joint space for diagnosing and treating associated pathological conditions, with a minimally invasive procedure. PMID:26401498

  8. Effects of central activation of serotonin 5-HT2A/2C or dopamine D2/3 receptors on the acute and repeated effects of clozapine in the conditioned avoidance response test

    Rationale: Acute administration of clozapine (a gold standard of atypical antipsychotics) disrupts avoidance response in rodents, while repeated administration often causes a tolerance effect. Objective: The present study investigated the neuroanatomical basis and receptor mechanisms of acute and repeated effects of clozapine treatment in the conditioned avoidance response test in male Sprague-Dawley rats. Methods: DOI (2,5-dimethoxy-4-iodo-amphetamine, a preferential 5-HT2A/2C agonist) or quinpirole (a preferential dopamine D2/3 agonist) was microinjected into the medial prefrontal cortex (mPFC) or nucleus accumbens shell (NAs), and their effects on the acute and long-term avoidance-disruptive effect of clozapine were tested. Results: Intra-mPFC microinjection of quinpirole enhanced the acute avoidance disruptive effect of clozapine (10 mg/kg, sc), while DOI microinjections reduced it marginally. Repeated administration of clozapine (10 mg/kg, sc) daily for 5 days caused a progressive decrease in its inhibition of avoidance responding, indicating tolerance development. Intra-mPFC microinjection of DOI at 25.0 (but not 5.0) μg/side during this period completely abolished the expression of clozapine tolerance. This was indicated by the finding that clozapine-treated rats centrally infused with 25.0 μg/side DOI did not show higher levels of avoidance responses than the vehicle-treated rats in the clozapine challenge test. Microinjection of DOI into the mPFC immediately before the challenge test also decreased the expression of clozapine tolerance. Conclusions: Acute behavioral effect of clozapine can be enhanced by activation of the D2/3 receptors in the mPFC. Clozapine tolerance expression relies on the neuroplasticity initiated by its antagonist action against 5-HT2A/2C receptors in the mPFC. PMID:25288514

    It is well known that psychotropic drugs can induce EEG alterations. Dose dependence seems established; however, there are no data concerning the impact of plasma levels. The authors investigated the influence of clozapine plasma levels on the frequency of EEG alterations. Data from 29 inpatients (18 male, 11 female, 31.7 +/- 10.2 years) receiving clozapine in a dose range between 25 and 600 mg were collected prospectively. There was no psychotropic or anticholinergic comedication. All patients had normal EEGs before taking clozapine. Fifteen patients showed pathological changes (group 2) and 14 no changes (group 1). Discriminant analysis showed that EEG changes are dependent on plasma levels (P = 0.0009, plasma levels in group 1 mean 81.6 ng/ml, +/- SD 64.6, in group 2 235.7 ng/ml, +/- 169.8). A total of 72.4% of the patients were correctly classified as having either pathological EEG changes or none by this analysis. Variables such as dose, age, sex, weight and duration of treatment were not statistically relevant. It can therefore be suggested that clozapine plasma levels are a valid indicator for the appearance of electrophysiological reactions. PMID:7846212

  10. Evaluation and treatment of chronic renal failure.

    Chronic renal failure (CRF) is the irreversible deterioration of renal function that gradually progresses to end stage renal disease (ESRD). The chief causes of CRF include obstructive uropathy, primary glomerular diseases, reflux nephropathy and hypoplastic or dysplastic kidneys. Progressive hyperperfusion and hyperfiltration causes increasing glomerular injury and further renal damage. Symptoms of CRF are usually seen when GFR is between 10-25% of normal. Children with severe CRF often suffer from failure to thrive, growth retardation, acidosis, anemia and renal osteodystrophy. Management of CRF aims at retarding progression of renal damage and treatment of complications related to renal dysfunction. Measures suggested to retard progression include protein restriction, strict control of hypertension, use of angiotensin converting enzyme inhibitors and control of hyperlipidemia. Appropriate amounts of protein and calories are recommended to prevent growth failure. Nutritional supplements are often required. The availability of recombinant erythropoietin, calcitriol and human growth hormone has significantly improved the management of these patients. Once ESRD supervenes, renal replacement therapy in the form of chronic peritoneal or hemodialysis and transplantation is necessary.

    Insomnia is a disorder characterized by inability to sleep or a total lack of sleep, prevalence of which ranges from 10 to 15% among the general population with increased rates seen among older ages, female gender, White population and presence of medical or psychiatric illness. Yet this condition is still under-recognized, under-diagnosed, and under-treated. This article aims to review the operational definitions and management of chronic insomnia. A computerized search on PubMed carried from 1980 to January 2009 led to the summarization of the results. There are several strategies to manage chronic insomnia. To initiate treatment, it is necessary to define it and differentiate it from other co-morbid psychiatric disorders. Non-pharmacologic strategies such as stimulus control therapy and relaxation and cognitive therapies have the best effect sizes followed by sleep restriction, paradoxical intention and sleep hygiene education which have modest to less than modest effect sizes. Among pharmacotherapeutic agents, non-benzodiazepine hypnotics are the first line of management followed by benzodiazepines, amitryptiline and antihistaminics. However, adequate trials of combined behavior therapy and pharmacotherapy are the best course of management. PMID:20814491

    Systemic arterial hypertension (SAH) is a progressive cardiovascular syndrome caused by complex and interrelated causes. The early markers of this syndrome are often present even before the blood pressure (BP) elevation; therefore, SAH cannot only be classified by the BP elevation threshold, which sometimes is discreet. Its progression is strongly associated with structural and functional cardiovascular abnormalities, which lead to end-organ damage (heart, kidney, brain, blood vessels and other organs), and cause premature morbidity and death. In this sense, the BP is only a biomarker of this cardiovascular syndrome, which is why it is more useful to consider individual BP patterns of the ill patient rather than a single BP threshold. The study and treatment of hypertension in chronic kidney disease (CKD) has made some progresses, especially in patients requiring dialysis. The use of non-invasive technology to register the BP has reconfigured health care of patients in regards to the diagnosis, circadian pattern, clinical surveillance, pharmacological prescription, prognosis, and risk of cardiovascular events (as well as mortality). The opportunity in the diagnosis and treatment means a delay in the onset of complications and, also, of dialysis. The blockade of the renin-aldotensin-aldosterone system (RAAS), a regular monitoring of the dry weight of the population in dialysis, and non-pharmacological interventions to modify lifestyle are the maneuvers with greater impact on the morbidity and mortality of patients.

    Chronic venous disease (CVD) affects at least 15-25 % of the general population incurring not only high morbidity but also considerable economical burden. The mainstay of modern treatment of CVD are endovenous therapeutic procedures and compression therapy. As far as the pathogenesis of CVD is being gradually unraveled the interest in drugs able to impact the process is growing. Here we have presented an overview of a majority of oral preparations used so far to treat CVD including venous leg ulcers. After several decades of clinical use a few flavonoid preparations, in the first place micronized purified flavonoid fraction, collected enough evidence to recommend them as a short-term adjunct treatment of CVD. However, other compounds are also promising in this regards. Yet, we need more larger and longer-term clinical trials to more precisely define effects, cost-effectiveness and, above all, capacity for prophylactic application of the drugs. Learning more about basis of CVD will help design new drugs directed at specific aspects of the disease process. PMID:27379855

  15. Pegloticase: in treatment-refractory chronic gout.

    Intravenous pegloticase offers a novel approach to treating chronic gout refractory to conventional therapy. Pegloticase is a recombinant polyethylene glycol-conjugated form of uricase (a uric acid-specific enzyme lacking in humans) that catalyses the oxidation of uric acid to allantoin. In randomized, placebo-controlled, double-blind, 6-month, phase III trials, intravenous pegloticase 8 mg every 2 or 4 weeks provided sustained reductions in plasma uric acid levels to less than the therapeutic target of 6 mg/dL in a substantial proportion of patients with chronic gout who were refractory to, or intolerant of, conventional urate-lowering therapy. Pegloticase 8 mg every 2 weeks was associated with disease-modifying benefits relative to placebo, as shown by significant improvements from baseline in tophi resolution, frequency of gout flares and tender joint count, and clinically relevant and statistically significant improvements from baseline in health-related quality-of-life parameters related to disability, pain and physical function. Pegloticase 8 mg every 4 weeks was also significantly more effective than placebo with regard to most, but not all, of these endpoints. Preliminary data from an open-label extension of the phase III trials indicate that long-term treatment with pegloticase 8 mg every 2 or 4 weeks may maintain plasma uric acid normalization in patients who experienced a sustained uric acid response during the phase III trials. The most common serious adverse events associated with pegloticase are gout flares, infusion reactions and anaphylaxis. In addition, exacerbation of pre-existing congestive heart failure was reported in 2% of patients receiving pegloticase 8 mg every 2 weeks in the phase III trials.

    Cannabis use disorders (CUDs) are highly comorbid in patients with schizophrenia and are associated with poor outcome. Clozapine has been put forward as the first choice antipsychotic in this comorbid group. However, little is known about the mechanisms underlying the assumed superiority of clozapine. We compared the effects of clozapine and risperidone on attentional bias, subjective craving and associated regional brain activity in patients with schizophrenia and CUD. Overall, 36 patients with schizophrenia and 19 healthy controls were included. Patients were randomised to antipsychotic treatment with clozapine or risperidone. At baseline and after 4 weeks of medication use, regional brain responses were measured during a classical Stroop and a cannabis word Stroop using functional magnetic resonance imaging. Clozapine-treated CUD patients showed a larger reduction in craving and in activation of the insula during the cannabis word Stroop, while risperidone-treated patients showed a larger decrease in activation of the right anterior cingulate cortex during the classical Stroop. A significant association was found between decreases in subjective craving and decreases in insula activation during the cannabis word Stroop. These findings strongly suggest that clozapine may be a better treatment choice in patients with schizophrenia and CUD than risperidone. PMID:24646809

    The purpose of this paper is to assess the results obtained with the arthroscopy-assisted surgical technique for the treatment of chronic acromioclavicular joint instability (CACJI), based on non-rigid coracoclavicular (CC) fixation and anatomical CC reconstruction with a tendinous allograft. Patients with CACJI who underwent surgery between 2008 and 2012 were included in the study. Clinical assessments included SF36, VAS and DASH, applied at the preoperative visit (POV) and at the last follow-up visit (LFUV). The Constant score and the General Satisfaction Score (0-10) were applied at the last follow-up visit. Occurrence of secondary subluxations was assessed. Ten patients were included; mean age was 41 years (range 33-55). Mean follow-up was 25.50 months (range 24-30). Surgical treatment was indicated in all patients after failure of conservative treatment. Questionnaires applied at the POV and the LFUV showed the following results: 1. SF36: physical, POV = 29.60 ± 3.41 and LFUV = 59.58 ± 1.98 (p = 0.000); 2. SF36 mental, POV = 46.57 ± 3.80 and LFUV = 56.62 ± 1.89 (p = 0.000); 3. VAS: POV = 5.17 ± 2.40 and LFUV: 1.67 ± 2.07 (p = 0.022); and 4. DASH: POV = 63.33 ± 23.56 and LFUV = 2.61 ± 1.79 (p = 0.000). The Constant score and the general satisfaction at the LFUV were 95.56 ± 3.28 and 9.22 ± 0.67, respectively. There were no secondary subluxations. Treatment of CACJI with a CC suspension device and arthroscopically-assisted anatomical reconstruction of CC ligaments may provide a significant quality of life improvement to patients. It is a strategy that, upon considering primary mechanical CC fixation, may minimize the chance of failure and occurrence of secondary subluxations. PMID:26999968

    Forty-two patients were evaluated and treated during the past five years at the Union Memorial Hospital Hand Center with the diagnosis of chronic digital ischemia. These patients with this syndrome, manifested by pain, severe cold intolerance and occasional tip ulceration, all were failures of conventional conservative treatment of vasodilators, tobacco abstinence and beta blocking agents. The evaluation consisted of first ruling out large vessel disease by noninvasive techniques of angiography. The patients underwent a variety of noninvasive diagnostic tests including Doppler examination, pulse volume recordings with cold stress, radioisotope scanning of the digital circulation and peripheral sympathetic block of the digital nerves. Treatment included direct microvascular reconstruction of the distal ulnar or radial artery and palmar arch, in ten patients, thermal biofeedback, in 22 patients and a new surgical procedure-digital sympathectomy, in ten patients, involving 18 digits. Eight of ten patients with palmar arch reconstruction improved with seven of ten having patent vein grafts. Thermal biofeedback has been helpful in 20 patients. Testing shows that an increase in digital perfusion can be initiated by all patients. However, only 70% can achieve this improvement. Digital sympathectomy consists of isolating the terminal branches of the sympathetic nerves which travel with the peripheral nerves, dividing these branches and stripping the adventitia of the digital arteries. Eight of nine patients have the experienced improvement in digital circulation, as manifested by pulse volume recordings after operation and radioisotope studies. Pain is substantially alleviated and the ulcers healed. All of these patients responded before operation to the digital nerve block with measured increased in digital perfusion. PMID:7247519

    Clozapine is an effective antipsychotic for treatment-resistant schizophrenia, but can cause fatal hematopoietic toxicity as agranulocytosis. To elucidate the mechanism of hematopoietic toxicity induced by clozapine, we developed an in vitro assay system using HL-60 cells, and investigated the effect on hematopoiesis. HL-60 cells were differentiated by all-trans retinoic acid (ATRA) into three states according to the following hematopoietic process: undifferentiated HL-60 cells, those undergoing granulocytic ATRA-differentiation, and ATRA-differentiated granulocytic cells. Hematopoietic toxicity was evaluated by analyzing cell survival, cell proliferation, granulocytic differentiation, apoptosis, and necrosis. In undifferentiated HL-60 cells and ATRA-differentiated granulocytic cells, both clozapine (50 and 100μM) and doxorubicin (0.2µM) decreased the cell survival rate, but olanzapine (1-100µM) did not. Under granulocytic differentiation for 5days, clozapine, even at a concentration of 25μM, decreased survival without affecting granulocytic differentiation, increased caspase activity, and caused apoptosis rather than necrosis. Histamine H4 receptor mRNA was expressed in HL-60 cells, whereas the expression decreased under granulocytic ATRA-differentiation little by little. Both thioperamide, a histamine H4 receptor antagonist, and DEVD-FMK, a caspase-3 inhibitor, exerted protection against clozapine-induced survival rate reduction, but not of live cell counts. 4-Methylhistamine, a histamine H4 receptor agonist, decreased the survival rate and live cell counts, as did clozapine. HL-60 cells under granulocytic differentiation are vulnerable under in vitro assay conditions to hematopoietic toxicity induced by clozapine. Histamine H4 receptor is involved in the development of clozapine-induced hematopoietic toxicity through apoptosis, and may be a potential target for preventing its occurrence through granulocytic differentiation.

    N-desmethylclozapine (NDMC or norclozapine) is the major active metabolite of the antipsychotic clozapine in humans. The activity of NDMC differs from clozapine at a number of neurotransmitter receptors, probably influencing the pharmacological effects of clozapine treatment. Here, we tested the properties of NDMC in comparison with clozapine at recombinant human dopamine D(2) and serotonin 5-HT(1A) receptors, using a panel of functional assays implicating diverse signalling pathways. At dopamine D(2) receptors, NDMC as well as clozapine did not display agonist activity in measures of G protein activation by [(35)S]GTPγS binding and in the sensitive Extracellular Signal-Regulated Kinase 1/2 (ERK1/2) phosphorylation assay. In contrast, there were weak partial agonist actions of NDMC (but not of clozapine) for dopamine D(2)-dependent activation of Ca(2+) liberation via coexpressed chimeric Gα(q/o) proteins and for G protein-coupled inward rectifier potassium channel (GIRK) current induction in Xenopus oocytes. Intriguingly, GIRK currents induced by NDMC via dopamine D(2) receptors showed a rapid and transient time course, strikingly different from currents recorded with other receptor agonists. At serotonin 5-HT(1A) receptors, NDMC was a more efficacious partial agonist than clozapine for [(35)S]GTPγS binding, ERK1/2 phosphorylation and GIRK activation. Respective low and moderate partial agonist properties of NDMC at dopamine D(2) and serotonin 5-HT(1A) receptors thus differentiate the metabolite from its parent drug and may contribute to the overall effects of clozapine pharmacotherapy.

    Clozapine is the only evidence-based therapy for treatment-resistant schizophrenia, but it induces agranulocytosis, a rare but potentially fatal haematological adverse reaction, in less than 1% of users. To improve safety, the drug is subject to mandatory haematological monitoring throughout the course of treatment, which is burdensome for the patient and one of the main reasons clozapine is underused. Therefore, a pharmacogenetic test is clinically useful if it identifies a group of patients for whom the agranulocytosis risk is low enough to alleviate monitoring requirements. Assuming a genotypic marker stratifies patients into a high-risk and a low-risk group, we explore the relationship between test sensitivity, group size and agranulocytosis risk. High sensitivity minimizes the agranulocytosis risk in the low-risk group and is essential for clinical utility, in particular in combination with a small high-risk group. PMID:25732907

    OBJECTIVE: To investigate the effects of 12 weeks of clozapine treatment on levels of cholesterol and related lipids in patients with schizophrenia. DESIGN: Prospective study. SETTING: University department associated with a teaching hospital. PARTICIPANTS: Eight patients (6 women and 2 men) with a clinical diagnosis of schizophrenia consistent with DSM-IV criteria. The patients were classified as treatment-resistant and had not responded to treatment with at least 2 conventional antipsychotics. INTERVENTIONS: Current antipsychotic medications were tapered and treatment with clozapine was initiated. OUTCOME MEASURES: Cholesterol and serum lipid levels, as well as Brief Psychiatric Rating Scale (BPRS) scores were measured before and after 12 weeks of treatment with clozapine. RESULTS: Clozapine treatment significantly improved the BPRS scores but did not significantly alter serum lipid levels, except triglyceride levels, which increased. CONCLUSION: The previously reported lower levels of cholesterol in treatment-resistant patients with schizophrenia cannot be attributed to the effects of clozapine administration. Further research is required to support and clarify the effects of antipsychotic drugs on lipid levels. Images Fig. 1 PMID:10586536

    Introduction: Chronic orchialgia is historically and currently a challenging disease to treat. It is a diagnostic and therapeutic challenge for physicians. Conservative therapy has served as the first line of treatment. For those who fail conservative therapy, surgical intervention may be required. We aim to provide a review of currently available surgical options and novel surgical treatment options. Methods: A review of current literature was performed using PubMed. Literature discussing treatment options for chronic orchialgia were identified. The following search terms were used to identify literature that was relevant to this review: Chronic orchialgia, testicular pain, scrotal content pain, and microsurgical denervation of the spermatic cord (MDSC). Results: The incidence of chronic orchialgia has been increasing over time. In the USA, it affects up to 100,000 men per year due to varying etiologies. The etiology of chronic orchialgia can be a confounding problem. Conservative therapy should be viewed as the first line therapy. Studies have reported poor success rates. Current surgical options for those who fail conservative options include varicocelectomy, MDSC, epididymectomy, and orchiectomy. Novel treatment options include microcryoablation of the peri-spermatic cord, botox injection, and amniofix injection. Conclusion: Chronic orchialgia has been and will continue to be a challenging disease to treat due to its multiple etiologies and variable treatment outcomes. Further studies are needed to better understand the problem. Treatment options for patients with chronic orchialgia are improving. Additional studies are warranted to better understand the long-term durability of this treatment options. PMID:26941490

    Chronic pain in the orofacial region has always been a vexing problem for dentists to diagnose and treat effectively. For trigeminal neuropathic pain, there are 3 medications (gabapentinoids, tricyclic antidepressants, and serotonin-norepinephrine reuptake inhibitors) to use plus topical anesthetics that have therapeutic efficacy. For chronic daily headaches (often migraine in origin), 3 prophylactic medications have reasonable therapeutic efficacy (β-blockers, tricyclic antidepressants, and antiepileptic drugs). The 3 Food and Drug Administration-approved drugs for fibromyalgia (pregabalin, duloxetine, and milnacipran) are not robust, with poor efficacy. For osteroarthritis, nonsteroidal anti-inflammatory drugs have therapeutic efficacy and when gastritis contraindicates them, corticosteriod injections are helpful. PMID:27475515

    Background Like fear conditioning, the acquisition phase of extinction involves new learning that is mediated by the amygdala. During extinction training, the conditioned stimulus is repeatedly presented in the absence of the unconditioned stimulus and the expression of previously learned fear gradually becomes suppressed. Our previous study revealed that chronic treatment with a selective serotonin reuptake inhibitor (SSRI) impairs the acquisition of auditory fear conditioning. To gain further insight into how SSRIs affect fear learning, we tested the effects of chronic SSRI treatment on the acquisition of extinction. Methods Rats were treated chronically (22 days) or subchronically (9 days) with the SSRI citalopram (10 mg/kg/day) before extinction training. The results were compared to those following chronic and subchronic treatment with tianeptine (10 mg/kg/day), an antidepressant with a different method of action. The expression of the NR2B subunit of the NMDA receptor in the amygdala was examined after behavioral testing. Results Chronic but not subchronic administration of citalopram impaired the acquisition of extinction and downregulated the NR2B subunit of the NMDA receptor in the lateral and basal nuclei of the amygdala. Similar behavioral and molecular changes were found with tianeptine treatment. Conclusions These results provide further evidence that chronic antidepressant treatment can impair amygdala-dependent learning. Our findings are consistent with a role for glutamatergic neurotransmission in the final common pathway of antidepressant treatment. PMID:23260230

    The atypical antipsychotic drug clozapine has multiple pharmacological actions, some of which, including 5-hydroxytryptamine (5-HT₂) and histamine (H₁) receptor antagonist effects, are shared by the non-selective 5-HT receptor antagonist cyproheptadine. Atypical antipsychotics have a characteristic profile of action on operant behaviour maintained by progressive ratio schedules, as revealed by Killeen's (1994) mathematical model of schedule controlled behaviour. These drugs increase the values of a parameter that expresses the 'incentive value' of the reinforcer (a) and a parameter that is inversely related to the 'motor capacity' of the organism (δ). This experiment examined the effects of acute treatment with cyproheptadine and clozapine on performance on a progressive ratio schedule of food reinforcement in rats; the effects of a conventional antipsychotic, haloperidol, and two drugs with food intake-enhancing effects, chlordiazepoxide and Δ⁹-tetrahydrocannabinol (THC), were also examined. Cyproheptadine (1, 5 mg kg⁻¹) and clozapine (3.75, 7.5 mg kg⁻¹) increased a and δ. Haloperidol (0.05, 0.1 mg kg⁻¹) reduced a and increased δ. Chlordiazepoxide (3, 10 mg kg⁻¹) increased a but reduced δ. THC (1, 3 mg kg⁻¹) had no effect. Interpretation based on Killeen's (1994) model suggests that cyproheptadine and clozapine enhanced the incentive value of the reinforcer and impaired motor performance. Motor impairment may be due to sedation (possibly reflecting H₁ receptor blockade). Enhancement of incentive value may reflect simultaneous blockade of H₁ and 5-HT₂ receptors, which has been proposed as the mechanism underlying the food intake-enhancing effect of cyproheptadine. In agreement with previous findings, haloperidol impaired motor performance and reduced the incentive value of the reinforcer. Chlordiazepoxide's effect on a is consistent with its food intake-enhancing effect.

    The literature to find the best approach to correct a chronic mallet finger deformity has been reviewed. All the evidence we found was type IV mallet finger injury, based on the CEBM classification. In the European literature, if correction of the proximal interphalangeal joint is not needed, and surgery is to be done on the distal interphalangeal joint only, then the most frequently reported technique involves the conversion of the chronic injury into an acute one by excising the scar and part of the joint capsule, and the extensor tendon is reattached with minor variations. An 80% to 100% success rate can be expected. In the US literature, the Fowler release is favored, but it does not reliably correct a flexion deformity of more than 35 degrees. Spiral retinacular reconstruction provides an excellent solution if the associated swan neck deformity needs to be corrected. PMID:21467915

    Clozapine (Leponex(®)), the main neuroleptic indicated in the treatment of resistant schizophrenia, requires therapeutic monitoring because of its side effects and the individual variability in metabolism. In addition, several cases of intoxication by this drug were described in the literature. In this work, we studied the indirect dosage of clozapine by selective electrode to the iodides for the optimization of an analytical protocol allowing therapeutic monitoring and the diagnosis of intoxication and/or overdose. Our results showed that the developed method is linear between 0.05 and 12.5 µg/mL (r = 0.980), with a limit of detection of 0.645.10(-3) µg/mL. It presents good precision (coefficient of variation less than 4%) and accuracy (coefficient less than 10%) for all the studied concentrations. With a domain of linearity covering a wide margin of concentrations, this method can be applicable to the dosage of clozapine in tablets and in different biological matrices, such as plasma, urines, and postmortem samples.

    Chronic cough is a frustrating and common problem, resulting in significant psychological and physical sequelae as well as enormous financial costs in terms of health care expense and time lost from work. Decreased QoL and depression are common. However, using a systematic approach, including assessing whether the patient uses ACE-I and cigarettes, excluding the presence of red flags and risk factors for life-threatening diseases, and obtaining and normal chest radiograph, more than 90% of cases of chronic cough are diagnosed as being caused by UACS, asthma, or GERD. It is recommended to address these conditions sequentially, starting with UACS. Nonasthmatic eosinophilic bronchitis and pertussis infections are unrecognized by primary care providers and should be considered after UACS, asthma, and GERD have been addressed. Finally, cough hypersensitivity syndrome is a new area of research and has been hypothesized to be the underlying factor in many cases of chronic cough, regardless of the inciting factor. More clinical research is needed to further elucidate the cough reflex pathway and the factors involved in modulating its sensitivity, which may eventually lead to new antitussive therapeutics.

    2014-12-01

    Back pain is a significant medical problem and one of the most common causes of medical consultations and missed work. In acute low back pain, patients with "red flags" indicating a serious underlying spinal or extraspinal disease must be identified by medical evaluation. Most cases of acute back pain are non-specific, and education, physical activity and pain medication is recommended. In addition, yellow flags (risks of developing chronic pain) should be recognized. The management of low back pain has been addressed by the German National Disease Management Guideline (NVL) low back pain published in 2010. This guideline evaluates the evidence and effectiveness of diagnostic and therapeutic interventions with a focus on nonspecific back pain. For chronic nonspecific low back pain intervention based on nondrug and drug therapy and a multiprofessional assessment is recommended. In patients with chronic inflammatory low back pain with onset before the age of 45, rheumatic spondyloarthritis should be considered. Recently, a guideline (S3-Leitlinie) for the management of axial spondyloarthritis including ankylosing spondylitis has become available. It provides evidence of physical and drug therapy including nonsteroidal antirheumatic and Tumor necrosis factor (TNF) inhibitor therapy. PMID:25465277

    Chronic finger extensor apparatus injuries are the result of the initial acute treatment having failed or being flawed. Because of their chronic nature, these injuries present various amounts of tendon retraction, tendon callus lengthening, peritendinous scar adhesions, static and dynamic imbalances with the flexor apparatus and intrinsic muscles, and joint contractures. This article will review the anatomy of the extensor mechanism and then will outline by location, the various clinical pictures that are secondary to chronic tendon injury. The clinical presentation of these injuries can be highly variable but their symptomatology and treatment are very specific. Of the possible therapeutic strategies for chronic mallet finger with or without associated swan-neck deformity, chronic boutonniere deformity, chronic sagittal band injuries, old ruptures on the dorsum of the wrist and traumatic defects in multiple tissues, conservative treatment is often the main element. Secondary surgical repair is not free of complications, and the results are often lacking. Rehabilitation and orthotic bracing are an integral part of the management of these injuries, no matter which treatment method is being considered. PMID:26184651

    Chronic treatment of pain with opiate drugs can lead to analgesic tolerance and drug dependence. Although all opiate drugs can promote tolerance and dependence in practice, the severity of those unwanted side effects differs depending on the drug used. Although each opiate drug has its own unique set of pharmacological profiles, methadone is the only clinically used opioid drug that produces substantial receptor endocytosis at analgesic doses. Here, we examined whether moderate doses of methadone carry any benefits over chronic use of equianalgesic morphine, the prototypical opioid. Our data show that chronic administration of methadone produces significantly less analgesic tolerance than morphine. Furthermore, we found significantly reduced precipitated withdrawal symptoms after chronic methadone treatment than after chronic morphine treatment. Finally, using a novel animal model with a degrading μ-opioid receptor we showed that, although endocytosis seems to protect against tolerance development, endocytosis followed by receptor degradation produces a rapid onset of analgesic tolerance to methadone. Together, these data indicated that opioid drugs that promote receptor endocytosis and recycling, such as methadone, may be a better choice for chronic pain treatment than morphine and its derivatives that do not.

    St John's wort (Hypericum perforatum) is notorious for its ability to induce the enzymes of the P450 system. Especially, it induces CYP1A2 and CYP3A4, enzymes that are closely involved in the metabolism of clozapine. We present a patient with schizophrenia, who was stable on a fixed dose with stable plasma level of clozapine, and who deteriorated after she started self-medicating with St John's wort. The reduced plasma clozapine level and the psychiatric condition normalized after the withdrawal of St John's wort. It is possible that, beside the induction of P450-enzymes, the induction of P-glycoprotein by St John's wort aggravated psychiatric deterioration of the patient. Physicians should be alert to patients self-medicating with over-the-counter medicines, especially when these medicines can lower clozapine concentrations below the therapeutic range.

    2016-01-01

    Pain is a complex and multidimensional perception, embodied in our daily experiences through interoceptive appraisal processes. The article reviews the recent literature about interoception along with predictive coding theories and tries to explain a missing link between the sense of the physiological condition of the entire body and the perception of pain in chronic conditions, which are characterized by interoceptive deficits. Understanding chronic pain from an interoceptive point of view allows us to better comprehend the multidimensional nature of this specific organic information, integrating the input of several sources from Gifford's Mature Organism Model to Melzack's neuromatrix. The article proposes the concept of residual interoceptive images (ghosts), to explain the diffuse multilevel nature of chronic pain perceptions. Lastly, we introduce a treatment concept, forged upon the possibility to modify the interoceptive chronic representation of pain through external input in a process that we call interoceptive modeling, with the ultimate goal of reducing pain in chronic subjects.

    Background: Sexual dysfunctions have been a major side effect of the second generation anti-psychotic drugs which often affects treatment compliance in patients with schizophrenia. There is no/few systematic review or research addressing sexual dysfunction and their effect on serum prolactin level among different atypical antipsychotics in India. Aims: To determine and compare the frequency of sexual dysfunction associated with olanzapine, risperidone, and clozapine and their effect on serum prolactin level in remitted patients with schizophrenia. Settings and Design: Cross-sectional hospital-based study. Recruitment by purposive sampling. Estimation of serum prolactin was done using enzyme-linked immunosorbent assay technique. Materials and Methods: The total sample size was 103, consisting of 31, 23, and 19 patients in olanzapine, risperidone, and clozapine groups, respectively and 30 controls. A Brief Psychiatric Rating Scale, Udvalg for Kliniske Undersogelser (UKU) Side Effect Rating Scale and Sexual Functioning Questionnaire were administered. Analysis of variance was used to compare clinical variables. Chi-square test was used to identify the frequency of sexual dysfunction. Kruskal–Wallis test was used to compare UKU side effect, sexual dysfunction, and blood parameters across the study groups. Results and Conclusion: Eighty-six percentage reported sexual dysfunction in one or more domains of sexual functioning in risperidone group as compared to 48.3% in olanzapine and 31% in clozapine groups, respectively. Prolactin level elevation was statistically significant in risperidone group followed by clozapine and olanzapine groups, respectively. PMID:26816428

    More than three million Americans have chronic hepatitis C infection, and the disease remains one of the most common blood-borne infections in the US. Treatment is focused on the chronic form of the disease, because the acute one tends to be self-limiting. In this article, we review the recent literature regarding the most effective therapy against hepatitis C infection, to confirm the current treatment of choice for the disease. We conclude that combination therapy with pegylated interferon and ribavirin remains the initial treatment of choice. New research focusing on adjuvant therapies, such as protease and polymerase inhibitors, has yielded early data that appear to be promising. PMID:21694905

    2013-01-01

    There is an increasing interest by doctors and patients in extracorporeal shock wave therapy (ESWT) for chronic plantar fasciopathy (PF), particularly in second generation radial extracorporeal shock wave therapy (RSWT). The present review aims at serving this interest by providing a comprehensive overview on physical and medical definitions of shock waves and a detailed assessment of the quality and significance of the randomized clinical trials published on ESWT and RSWT as it is used to treat chronic PF. Both ESWT and RSWT are safe, effective, and technically easy treatments for chronic PF. The main advantages of RSWT over ESWT are the lack of need for any anesthesia during the treatment and the demonstrated long-term treatment success (demonstrated at both 6 and 12 months after the first treatment using RSWT, compared to follow-up intervals of no more than 12 weeks after the first treatment using ESWT). In recent years, a greater understanding of the clinical outcomes in ESWT and RSWT for chronic PF has arisen in relationship not only in the design of studies, but also in procedure, energy level, and shock wave propagation. Either procedure should be considered for patients 18 years of age or older with chronic PF prior to surgical intervention. PMID:24004715

    To assess changing patterns of treatment for chronic anal fissure, a retrospective analysis of treatment for chronic anal fissure within one hospital between January 1990 and December 1996 was undertaken. A total of 221 patients received treatment for a chronic anal fissure in this period, of whom 209 had a surgical procedure. Manual dilatation of the anus was performed in 21 patients (10%) and has not been performed since 1995. Lateral internal sphincterotomy was performed in 183 patients (88%) and continues to be the mainstay of treatment. Five female patients (2%) were identified as having a sphincter defect by anal manometry combined with endoanal ultrasound and were treated by an anal advancement flap. From 1996 onwards, 15 patients (7%) were treated by topical glyceryl trinitrate (GTN) paste as the first line of treatment. Of these patients, nine have experienced healing of their fissure, and three have had relief of pain without healing of the fissure. Three have gone on to have a lateral internal sphincterotomy. Lateral internal sphincterotomy remains the primary form of treatment for chronic anal fissure. GTN cream has increasingly been offered as preliminary treatment over the last 12 months. Perioperative use of endoanal ultrasound allowed identification of patients who may be at high risk of postoperative incontinence from a sphincterotomy. An anal advancement flap has been used as an alternative surgical approach for these patients.

    Treating chronic pain in the context of opioid misuse can be very challenging. This paper explores the epidemiology and potential treatments for chronic pain and opioid misuse and identifies educational and regulation changes that may reduce diversion of opioid analgesics. We cover the epidemiology of chronic pain and aberrant opioid behaviors, psychosocial influences on pain, pharmacological treatments, psychological treatments, and social treatments, as well as educational and regulatory efforts being made to reduce the diversion of prescription opioids. There are a number of ongoing challenges in treating chronic pain and opioid misuse, and more research is needed to provide strong, integrated, and empirically validated treatments to reduce opioid misuse in the context of chronic pain.

    1 Cinnarizine, an inhibitor of calcium ion transport across smooth muscle cell membrane, has been shown to exert an anti-asthmatic effect in patients with chronic asthma. 2 It is postulated that antagonism to calcium ion transport across the mast cell membrane may cause the compound to have a pharmacological effect similar to sodium cromoglycate. 3 Cinnarizine is orally active and its therapeutic effect is demonstrated in a double-blind, cross-over, placebo controlled study. 4 Patient benefit was shown by a significant improvement in peak flow rate. A non-significant trend towards a reduction in symptomatic bronchodilator usage and a decrease in asthma symptom score was also shown. 5 It is concluded that cinnarizine could well prove to be the first of a new family of anti-asthmatic drugs offering a protective effect when taken systemically.

    Individuals with chronic widespread pain, including those with fibromyalgia, pose a particular challenge to treatment, given the modest effectiveness of pharmacological agents for this condition. The growing consensus indicates that the best approach to treatment involves the combination of pharmacological and non-pharmacological interventions. Several non-pharmacological interventions, particularly exercise and cognitive-behavioural therapy (CBT), have garnered good evidence of effectiveness as stand-alone, adjunctive treatments for patients with chronic pain. In this article, evidenced-based, non-pharmacological management techniques for chronic widespread pain are described by using two broad categories, exercise and CBT. The evidence for decreasing pain, improving functioning and changing secondary symptoms is highlighted. Lastly, the methods by which exercise and CBT can be combined for a multi-component approach, which is consistent with the current evidence-based guidelines of several American and European medical societies, are addressed.

    This systematic review addresses the pathophysiology, diagnostic evaluation, and treatment of several chronic pain syndromes affecting the pelvic organs: chronic proctalgia, coccygodynia, pudendal neuralgia, and chronic pelvic pain. Chronic or recurrent pain in the anal canal, rectum, or other pelvic organs occurs in 7% to 24% of the population and is associated with impaired quality of life and high health care costs. However, these pain syndromes are poorly understood, with little research evidence available to guide their diagnosis and treatment. This situation appears to be changing: A recently published large randomized, controlled trial by our group comparing biofeedback, electrogalvanic stimulation, and massage for the treatment of chronic proctalgia has shown success rates of 85% for biofeedback when patients are selected based on physical examination evidence of tenderness in response to traction on the levator ani muscle-a physical sign suggestive of striated muscle tension. Excessive tension (spasm) in the striated muscles of the pelvic floor appears to be common to most of the pelvic pain syndromes. This suggests the possibility that similar approaches to diagnostic assessment and treatment may improve outcomes in other pelvic pain disorders. PMID:22110274

    BACKGROUND: Among the chronic leg ulcers, venous ulcers are the most common and constitute a major burden to public health. Despite all technology available, some patients do not respond to established treatments. In our study, carboxymethylcellulose was tested in the treatment of refractory chronic venous ulcers. OBJECTIVE: To evaluate the efficacy of carboxymethylcellulose 20% on the healing of chronic venous ulcers refractory to conventional treatments. METHODS: This is an analytical, pre-experimental study. Thirty patients were included with refractory venous ulcers, and applied dressings with carboxymethylcellulose 20% for 20 weeks. The analysis was based on measurement of the area of ulcers, performed at the first visit and after the end of the treatment. RESULTS: There was a reduction of 3.9 cm2 of lesion area (p=0.0001), corresponding to 38.8% (p=0.0001). There was no interruption of treatment and no increase in lesion area in any patient. CONCLUSIONS: Carboxymethylcellulose 20% represents a low cost and effective therapeutic alternative for the treatment of refractory chronic venous ulcers. However, controlled studies are necessary to prove its efficacy. PMID:26982773

One patient died, 4 others had early interruption of treatment. Eleven of the 38 patients had efficient thrombolysis confirmed by arteriography. The facts confirm the possibility of thrombolysis during chronic arterial disease. The fact that the aggravation was recent was favourable factor in prognosis. The eleven patients improved, had severe aggravation of symptomes for less than 2 months. Thus thrombolytic treatment has a place of choice in the treatment of severe arterial disease where surgery is impossible, or dangerous, owing to the uncertain state of the vascular bed below the lesion. Efficacious, it permits reconstructive surgery in cases where it had been at first refused. The use of intermittent treatment, apart from advantages of confort and cost, seems to increase the efficacy of treatment.

    2010-01-01

    A chronic anal fissure is a common perianal condition. This review aims to evaluate both existing and new therapies in the treatment of chronic fissures. Pharmacological therapies such as glyceryl trinitrate (GTN), Diltiazem ointment and Botulinum toxin provide a relatively non-invasive option, but with higher recurrence rates. Lateral sphincterotomy remains the gold standard for treatment. Anal dilatation has no role in treatment. New therapies include perineal support devices, Gonyautoxin injection, fissurectomy, fissurotomy, sphincterolysis, and flap procedures. Further research is required comparing these new therapies with existing established therapies. This paper recommends initial pharmacological therapy with GTN or Diltiazem ointment with Botulinum toxin as a possible second line pharmacological therapy. Perineal support may offer a new dimension in improving healing rates. Lateral sphincterotomy should be offered if pharmacological therapy fails. New therapies are not suitable as first line treatments, though they can be considered if conventional treatment fails. PMID:21160880

    Prevalent in 14-17 % of the population, chronic pruritus is among the most common and stressful symptoms in medicine. In spite of new findings regarding the origin and chronification of the symptom, therapy remains a great challenge. There is a lack of approved therapies that provide rapid and efficient reduction of pruritus. As a result, the affected patients suffer a long time (even months to years), and somatic (scratch lesions, super infections, sleep disorders) and psychosomatic disorders develop. Interdisciplinary cooperation with various specialists is important not just for these reasons, but also due to different etiologies of the symptom and common comorbidities. In addition, there remains a great need for uniformly devised, clinically controlled studies, recommendations and guidelines. New therapeutic approaches are currently being verified in clinical trials. This allows for future prospects of possible new and partially targeted therapies. This article provides a summary of current therapeutic options based on case series, individual randomized controlled trials and the current S2K guideline. PMID:27351559

    Clozapine (CLZ) is the drug of choice for the treatment of resistant schizophrenia; however, its suitable use is limited by the complex adverse effects’ profile. The best-described adverse effects in the literature are represented by agranulocytosis, myocarditis, sedation, weight gain, hypotension, and drooling; nevertheless, there are other known adverse effects that psychiatrists should readily recognize and manage. This review covers the “rare” and “very rare” known adverse effects of CLZ, which have been accurately described in literature. An extensive search on the basis of predefined criteria was made using CLZ and its combination with adverse effects as keywords in electronic databases. Data show the association between the use of CLZ and uncommon adverse effects, including ischemic colitis, paralytic ileus, hematemesis, gastroesophageal reflux disease, priapism, urinary incontinence, pityriasis rosea, intertriginous erythema, pulmonary thromboembolism, pseudo-pheochromocytoma, periorbital edema, and parotitis, which are influenced by other variables including age, early diagnosis, and previous/current pharmacological therapies. Some of these adverse effects, although unpredictable, are often manageable if promptly recognized and treated. Others are serious and potentially life-threatening. However, an adequate knowledge of the drug, clinical vigilance, and rapid intervention can drastically reduce the morbidity and mortality related to CLZ treatment. PMID:26273202

    This study evaluates group treatment for women suffering from chronic pelvic pain. The concept of group treatment was based on psychosomatic and physio-therapeutical principles and on cognitive and operant behavioral therapy. Each group was composed of up to six women suffering from chronic pelvic pain, and two physiotherapists. Each group treatment session lasted 2.5 h per week for a period of 10 weeks. The women completed questionnaires and pain drawings four times during the treatment period from the beginning of the period till 15 months later. During 13 group treatment periods 53 women accomplished the treatment. Before the treatment the women had experienced pain for an average period of 5 years and 9 months (ranging from 6 months to 22 years). The women's descriptions of the changes derived from group treatment were analyzed according to the Grounded Theory Method. A methodical triangulation of quantitative and qualitative data as well as analyzes of the drawings were applied. One year after the end of the treatment, 39% of the women were pain-free. The average level of pain measured according to the Visual Analog Scale was reduced from 2.8 to 0.9 (p < 0.01). The intake rate of analgesics was reduced from an average of 8.5 units to 0.9 units per week (p < 0.01). Furthermore a reduction in the use of the National Health Service and increases in gainful employment were registered. By means of the Grounded Theory Analysis a model of the development process was elaborated. The process begins with the development of self-knowledge, followed by the woman assuming self responsibility for her own life and performing self-activeness. During the process the woman increases her feeling of self-control and personal mastery of her emotions. The women's pain drawings improved, resulting in more detailed drawings, the color intensity abating, the extent of pains declining, and the outlines blurring. In conclusion this kind of group treatment brings the women relief from

    Growing genetic evidence has implicated a role for neuregulin-1 (NRG-1) in schizophrenia pathogenesis as well as alterations in SNAP receptor (SNARE) proteins at both gene and protein levels in post-mortem investigations. In relation to a potential therapeutic mechanism for atypical antipsychotic medications, clozapine has been shown to increase both NRG-1 levels and synaptic markers in rodents. As evidence continues to mount for a potential restoration in connectivity by antipsychotic medications being a mode of efficacy we chose to examine the effects of the atypical antipsychotic clozapine and the typical antipsychotic haloperidol on NRG-1 and SNARE protein transcripts in a human brain aggregates exposed to plasma levels chronically for a period of three weeks. At the end of this exposure period we performed quantitative real-time PCR to investigate the mRNA levels of NRG-1, VAMP-1 and SNAP-25. Overall we found that clozapine had the ability to upregulate NRG-1 (+3.58 fold change) and VAMP-1 (+1.92) while SNAP-25 remained unchanged. Changes for haloperidol exposed aggregates were below our cut-off of +1.5. Overall the results of our investigation lend further support to atypical antipsychotic medications having the potential to increase levels of neurotrophic and synaptic markers such as NRG-1 and VAMP-1, the former being a strong candidate susceptibility gene for schizophrenia. In the absence of frank neuronal loss in schizophrenia, restoration of neuronal and synaptic functions by atypical antipsychotics in the brains of schizophrenics maybe a key mechanism of therapeutic efficacy by re-establishing normal connectivity and functioning.

    Chronic pruritus is a distressing symptom that is often refractory to treatment. Patients frequently fail topical therapies and oral over-the-counter antihistamines, prompting the clinician to consider alternative therapies such as neuroactive agents. Herein, the use of gabapentin and pregabalin, 2 medications well known for treating neuropathic pain and epilepsy that are occasionally used for relieving chronic pruritus is explored. The findings from original sources published to date to evaluate the use of gabapentin and pregabalin as antipruritic agents are explored. They are found to be promising alternative treatments for the relief of several forms of chronic pruritus, particularly uremic pruritus and neuropathic or neurogenic itch, in patients who fail conservative therapies.

    Imatinib mesylate has revolutionized the treatment landscape for patients with newly diagnosed chronic myeloid leukemia (CML). Imatinib at a dose of 400 mg/day is considered the standard treatment for all newly diagnosed chronic phase CML. Follow-up on the pivotal International Randomized Study of Interfreron versus STI571 (IRIS) study has shown excellent response rates, progression-free survival and overall survival after 8 years of follow-up. However, some patients will develop resistance to imatinib treatment due to a multitude of reasons. Numerous strategies to overcome resistance are available including dose escalation of imatinib, switching to a second generation tyrosine kinase inhibitor or to one of the newer non-tyrosine kinase inhibitors. This review guides the treating physician with a rational approach in the management of CML patients who fail initial treatment with imatinib or lose response while on therapy with imatinib.

    Chronic hand eczema is a common and often debilitating condition. Alitretinoin, a 9-cis-retinoic acid and pan-retinoic acid agonist, is a new and effective systemic treatment for chronic hand eczema, which provides another treatment option. A “clear” or “almost clear” response can be achieved in up to half of patients within a 24-week course of treatment. Even higher rates of remission can be obtained with a longer duration of treatment. Alitretinoin has a favorable overall profile of adverse effects; however, female patients who are at risk of becoming pregnant should follow a strict pregnancy-prevention program due to the teratogenic effects of this drug.

    A developed society is usually also characterized by an elderly population, which has a continuous percentage growth. This population frequently presents a cumulus of medical pathologies. With the development of the medication and surgical treatment of different affections, the life span has increased and the pathology of an old patient has diversified as far as the cumulus of various pathological diseases in the same person is concerned. Chronic subdural pathologies represent an affection frequently met in neurosurgery practice. Any neurosurgeon, neurologist and not only, has to be aware of the possibility of the existence of a chronic subdural haematoma, especially when the patient is old and is subjected to an anticoagulant or antiaggregant treatment, these 2 causes being by far the etiological factors most frequently met in chronic subdural haematomas. With an adequate diagnosis and treatment, usually surgical, the prognosis is favorable. Although the surgical treatment presents a categorical indication in most of the cases, the fact that there are many surgical techniques, a great relapse rate, as well as the numerous studies, which try to highlight the efficiency of a technique as compared to another, demonstrate that the treatment of these haematomas is far from reaching a consensus among the neurosurgeons. The latest conservatory treatment directions are still being studied and need many years to be confirmed. Abbreviations: CT = computerized tomography, MRI = magnetic resonance imaging PMID:26351527

    Clozapine displays stronger systemic metabolic side effects than haloperidol and it has been hypothesized that therapeutic antipsychotic and adverse metabolic effects of these drugs are related. Considering that cerebral disconnectivity through oligodendrocyte dysfunction has been implicated in schizophrenia, it is important to determine the effect of these drugs on oligodendrocyte energy metabolism and myelin lipid production. Effects of clozapine and haloperidol on glucose and myelin lipid metabolism were evaluated and compared in cultured OLN-93 oligodendrocytes. First, glycolytic activity was assessed by measurement of extra- and intracellular glucose and lactate levels. Next, the expression of glucose (GLUT) and monocarboxylate (MCT) transporters was determined after 6 and 24 h. And finally mitochondrial respiration, acetyl-CoA carboxylase, free fatty acids, and expression of the myelin lipid galactocerebroside were analyzed. Both drugs altered oligodendrocyte glucose metabolism, but in opposite directions. Clozapine improved the glucose uptake, production and release of lactate, without altering GLUT and MCT. In contrast, haloperidol led to higher extracellular levels of glucose and lower levels of lactate, suggesting reduced glycolysis. Antipsychotics did not alter significantly the number of functionally intact mitochondria, but clozapine enhanced the efficacy of oxidative phosphorylation and expression of galactocerebroside. Our findings support the superior impact of clozapine on white matter integrity in schizophrenia as previously observed, suggesting that this drug improves the energy supply and myelin lipid synthesis in oligodendrocytes. Characterizing the underlying signal transduction pathways may pave the way for novel oligodendrocyte-directed schizophrenia therapies. PMID:25477781

    Clozapine is an atypical antipsychotic drug used in the treatment of schizophrenia, which has been shown to reverse behavioural and dendritic spine deficits in mice. It has recently been shown that deficiency of 14-3-3ζ has an association with schizophrenia, and that a mouse model lacking this protein displays several schizophrenia-like behavioural deficits. To test the effect of clozapine in this mouse model, 14-3-3ζ KO mice were administered clozapine (5mg/kg) for two weeks prior to being analysed in a test battery of cognition, anxiety, and despair (depression-like) behaviours. Following behavioural testing brain samples were collected for analysis of specific anatomical defects and dendritic spine formation. We found that clozapine reduced despair behaviour of 14-3-3ζ KO mice in the forced swim test (FST) and altered the behaviour of wild types and 14-3-3ζ KO mice in the Y-maze task. In contrast, clozapine had no effects on hippocampal laminar defects or decreased dendritic spine density observed in 14-3-3ζ KO mice. Our results suggest that clozapine may have beneficial effects on clinical behaviours associated with deficiencies in the 14-3-3ζ molecular pathway, despite having no effects on morphological defects. These findings may provide mechanistic insight to the action of this drug.

The subjects were 62 patients, in whom the diagnosis was made using clinical and instrumental tests. The patients were divided into three groups. Group I received conventional pharmacotherapy; group II received a course of intravenous laser therapy in addition to it; group III received a course of laseropuncture and low-intensive laser irradiation of the hepatic area in addition to pharmacotherapy. The best results according to clinical and instrumental data were achieved in group III.

    Following cardiac transplantation, registry data has demonstrated a gradual improvement in survival over the last several decades, which is testament to continual improvement in aftercare strategy. However, a significant number of patients will eventually develop a new syndrome of chronic heart failure, owing to the multitude of physiological processes that occur after transplantation. This condition, referred to as chronic graft failure (CGF) should be regarded as a unique illness rather than one that is simply analogous with chronic heart failure. In particular, the unique pathophysiological (and pharmacological) environment in the setting of CGF presents a challenging situation to the transplant physician. There is uncertainty over which treatments to offer given a paucity of clinical trial data to support the use of standard heart failure treatments in CGF. In this review, we discuss which chronic heart failure treatments could be considered in the setting of CGF based on their mechanisms of action, benefits within the native heart failure setting, and the relevant issues within the posttransplant environment.

    Endoscopic argon plasma coagulation and bipolar electrocautery are currently preferred treatments for chronic radiation proctitis, but ulcerations and strictures frequently occur. Radiofrequency ablation (RFA) has been successful for mucosal ablation in the esophagus. Here we report the efficacy of RFA with the BarRx Halo90 system in three patients with bleeding from chronic radiation proctitis. In all cases, the procedure was well tolerated and hemostasis was achieved after 1 or 2 RFA sessions. Re-epithelialization of squamous mucosa was observed over areas of prior hemorrhage. No stricturing or ulceration was seen on follow-up up to 19 months after RFA treatment. Real-time endoscopic optical coherence tomography (EOCT) visualized epithelialization and subsurface tissue microvasculature pre- and post-treatment, demonstrating its potential for follow-up assessment of endoscopic therapies.

    Chronic idiopathic demyelinating polyradiculoneuropathy (CIDP) is a rare disease, the most frequent one within the spectrum of the so-called "chronic immune-mediated neuropathies". Challenges in the treatment of CIDP firstly concern its diagnosis, which may be difficult, mainly for the atypical forms. Secondly, challenges encompass the choice of the first-line treatment, such as corticosteroids, intravenous immunoglobulins (IVIg), and plasma exchanges (PE) that have been proven as efficacious by several randomized controlled trials (RCT). Recent reports have focused on both different regimens of corticosteroids, and the occurrence of relapses following treatment with either corticosteroids or IVIg. These data may be helpful for the choice of the first-line treatment and may result in changing the guidelines for treatment of CIDP in clinical practice. The third and more difficult challenge is to manage long-term treatment for CIDP, since no immunomodulatory treatment has to date been proven as efficacious in this situation. Lastly, challenges in the treatment concern the choice of the best outcome measure for CIDP in RCT and clinical practice. The aim of this article is to overview the results of the more recently reported published trials for CIDP, and to give some insights for the current and future management of CIDP.

    1999-01-01

    A chronic anal fissure may be regarded as an ischaemic ulcer. Until recently, its treatment necessitated surgical intervention to lower the tension of the internal sphincter (lateral internal sphincterotomy), or manual dilatation of the anus. A disadvantage of both methods is the risk of permanent sphincter injury resulting in reduced continence. Local application of ointment containing nitroglycerin (glyceryltrinitrate) or isosorbide dinitrate reduces the pressure at rest in the anal canal and increases the anodermal blood circulation. Both ointments in most patients lead to healing of the chronic anal fissure. Nitroglycerin ointment in a prospective, randomized trial brought about better healing than placebo treatment. The advantage of the ointment treatment, the needlessness of sphincterotomy, is particularly important in cases of existing sphincter abnormalities. It has the disadvantage that it takes longer for the fissure pain to abate. The principal side effect is headache. In over 50% of the patients the treatment has to be continued for longer than 6 weeks. Little is known as yet about the risk of recurrence. Before surgical interventions as the treatment of first choice can be definitely replaced by treatment with nitrate ointment the good results of the ointment treatment have to be confirmed. Also, more has to be found out about the risk of recurrence, the optimal duration of the treatment and the choice of the type of nitrate ointment.

    Separate lines of evidence have demonstrated the involvement of N-methyl-D-aspartate (NMDA) receptor and oligodendrocyte dysfunctions in schizophrenia. Here, we have carried out shotgun mass spectrometry proteome analysis of oligodendrocytes treated with the NMDA receptor antagonist MK-801 to gain potential insights into these effects at the molecular level. The MK-801 treatment led to alterations in the levels of 68 proteins, which are associated with seven distinct biological processes. Most of these proteins are involved in energy metabolism and many have been found to be dysregulated in previous proteomic studies of post-mortem brain tissues from schizophrenia patients. Finally, addition of the antipsychotic clozapine to MK-801-treated oligodendrocyte cultures resulted in changes in the levels of 45 proteins and treatment with clozapine alone altered 122 proteins and many of these showed opposite changes to the MK-801 effects. Therefore, these proteins and the associated energy metabolism pathways should be explored as potential biomarkers of antipsychotic efficacy. In conclusion, MK-801 treatment of oligodendrocytes may provide a useful model for testing the efficacy of novel treatment approaches. PMID:26973466

    2015-01-01

    Objectives: It has been repeatedly shown that clozapine is underutilized and there is delayed use of it in clinical practice. Method: An online survey was sent to 2771 consultant psychiatrists registered with the Royal College of Psychiatrists in the UK. A total of 243 responded to this survey. The survey elicited their views and experiences in using clozapine as well as to identify what may be the underlying causes for its underutilization. Results: Over 75% acknowledged that they had good training in using clozapine and about 56% had clozapine-dedicated service. However, 40.5% preferred to use several other antipsychotics prior to considering clozapine. A third felt it was not safe to start clozapine in the community and 42% had less than five patients on clozapine. Eleven possible reasons for clozapine underutilization were identified including concerns about side effects, patients not wanting to have blood tests and lack of experience or knowledge. Knowledge deficiency in certain aspects of clozapine use were identified, e.g. a third of respondents did not know that the risk of agranulocytosis changes with time, 42.7% did not think that clozapine can reduce substance use, while 20% were not aware of its benefit in reducing suicidal risk. Conclusions: Important areas of concern such as managing side effects and deficiency in evidence-based use of clozapine were identified. These can be targeted in training and professional development programme. PMID:26240748

    The present study examined the bioconcentration of 2 basic pharmaceuticals: verapamil (a calcium channel blocker) and clozapine (an antipsychotic compound) in 2 fresh water fishes, fathead minnow and channel catfish. In 4 separate bioconcentration factor (BCF) experiments (2 chemicals × 1 exposure concentration × 2 fishes), fathead minnow and channel catfish were exposed to 190 μg/L and 419 μg/L of verapamil (500 μg/L nominal) or 28.5 μg/L and 40 μg/L of clozapine (50 μg/L nominal), respectively. Bioconcentration factor experiments with fathead consisted of 28 d uptake and 14 d depuration, whereas tests conducted on catfish involved a minimized test design, with 7 d each of uptake and depuration. Fish (n = 4-5) were sampled during exposure and depuration to collect different tissues: muscle, liver, gills, kidneys, heart (verapamil tests only), brain (clozapine tests only), and blood plasma (catfish tests only). Verapamil and clozapine concentrations in various tissues of fathead and catfish were analyzed using liquid chromatography-mass spectrometry. In general, higher accumulation rates of the test compounds were observed in tissues with higher perfusion rates. Accumulation was also high in tissues relevant to pharmacological targets in mammals (i.e. heart in verapamil test and brain in the clozapine test). Tissue-specific BCFs (wet wt basis) for verapamil and clozapine ranged from 0.7 to 75 and from 31 to 1226, respectively. Tissue-specific concentration data were used to examine tissue-blood partition coefficients. PMID:26753615

    Plantar fasciitis, the most common cause of pain in the inferior heel, accounts for 11% to 15% of all foot symptoms requiring professional care among adults. The present study reports the results of a minimally invasive surgical treatment of chronic plantar fasciitis. All patients with plantar fasciitis who had undergone percutaneous latticed plantar fasciotomy at 3 clinical sites from March 2008 to March 2009 were included in the present study. The follow-up evaluations for this treatment were conducted using the Mayo clinical scoring system. We investigated 17 patients with recalcitrant chronic plantar fasciitis who had undergone this treatment within a follow-up period of ≥13 months. All procedures were performed in the clinic with the patient under local anesthesia. No wound infections or blood vessel or nerve damage occurred. At a mean follow-up period of 16.0 ± 2.29 (range 13 to 21) months, significant improvement was seen in the preoperative mean Mayo score (from 12.06 ± 2.54 to 89.76 ± 4.28, p < .001) and no patient had developed symptom recurrence. Also, none of the patients had developed complex regional pain syndrome. All patients were able to return to regular shoe wear by 3 weeks postoperatively. The technique of plantar fasciitis with percutaneous latticed plantar fasciotomy could be a promising treatment option for patients with recalcitrant chronic plantar fasciitis.

    Adult sleepwalking affects 2.5% of the general population and may lead to serious injuries. Fifty young adults with chronic sleepwalking were studied prospectively. Clinical evaluation, questionnaires from patients and bed partners, and polysomnography were obtained on all subjects in comparison with 50 age-matched controls. Subjects were examined for the presence of psychiatric anxiety, depression and any other associated sleep disorder. Isolated sleepwalking or sleepwalking with psychiatric disorders was treated with medication. All other patients with other sleep disorders were treated only for their associated problem. Prospective follow-up lasted 12 months after establishment of the most appropriate treatment. Patients with only sleepwalking, treated with benzodiazepines, dropped out of follow-up testing and reported persistence of sleepwalking, as did patients with psychiatric-related treatment. Chronic sleepwalkers frequently presented with sleep-disordered breathing (SDB). All these patients were treated only for their SDB, using nasal continuous positive airway pressure (CPAP). All nasal CPAP-compliant patients had control of sleepwalking at all stages of follow-up. Non-compliant nasal CPAP patients had persistence of sleepwalking. They were offered surgical treatment for SDB. Those successfully treated with surgery also had complete resolution of sleepwalking. Successful treatment of SDB, which is frequently associated with chronic sleepwalking, controlled the syndrome in young adults. PMID:15817520

  6. Update of Inpatient Treatment for Refractory Chronic Daily Headache.

    2016-01-01

    Chronic daily headache (CDH) is a group of headache disorders, in which headaches occur daily or near-daily (>15 days per month) and last for more than 3 months. Important CDH subtypes include chronic migraine, chronic tension-type headache, hemicrania continua, and new daily persistent headache. Other headaches with shorter durations (<4 h/day) are usually not included in CDH. Common comorbidities of CDH are medication overuse headache and various psychiatric disorders, such as depression and anxiety. Indications of inpatient treatment for CDH patients include poor responses to outpatient management, need for detoxification for overuse of specific medications (particularly opioids and barbiturates), and severe psychiatric comorbidities. Inpatient treatment usually involves stopping acute pain, preventing future attacks, and detoxifying medication overuse if present. Multidisciplinary integrated care that includes medical staff from different disciplines (e.g., psychiatry, clinical psychology, and physical therapy) has been recommended. The outcomes of inpatient treatment are satisfactory in terms of decreasing headache intensity or frequency, withdrawal from medication overuse, reducing disability, and improving life quality, although long-term relapse is not uncommon. In conclusion, inpatient treatment may be useful for select patients with refractory CDH and should be incorporated in a holistic headache care program.

  7. The chronic syndromes after previous treatment of pituitary tumours.

    Ultimately, almost all patients who are appropriately treated for pituitary tumours enter a chronic phase with control or cure of hormonal excess, adequate treatment of pituitary insufficiency and relief of mass effects. This phase is associated with improvement of initial signs and symptoms, but also with the persistent consequences of the initial disease and associated treatments. Pituitary insufficiency is a common denominator in many of these patients, and is associated with a reduction in quality of life, despite adequate endocrine substitution. Hypothalamic dysfunction can be present in patients previously treated for visual impairments caused by large suprasellar adenomas, or craniopharyngiomas. In addition to hypopituitarism, these patients can have multisystem morbidities caused by altered hypothalamic function, including weight gain and disturbed regulation of sleep-wake cycles. Mortality can also be affected. Patients cured of Cushing disease or acromegaly have chronic multisystem morbidities (in the case of Cushing disease, also affecting mortality) caused by irreversible effects of the previous excesses of cortisol in Cushing disease and growth hormone and insulin-like growth factor 1 in acromegaly. In addition to early diagnosis and treatment of pituitary tumours, research should focus on the amenability of these chronic post-treatment syndromes to therapeutic intervention, to improve quality of life and clinical outcomes.

  9. Evaluation and treatment of gout as a chronic disease.

    Perez-Ruiz, Fernando; Herrero-Beites, Ana Maria

    2012-11-01

    Gout is a disease caused by deposition of monosodium urate crystals in tissues. One of the limitations for successful treatment of gout is to consider it as an intermittent disease rather than a chronic inflammatory disease which, if improperly treated, leads to chronic clinical manifestations. In addition, gout is linked to increased cardiovascular morbidity and mortality.Urate-lowering therapy comprises both nonpharmacologic and pharmacologic interventions, but most patients will need urate-lowering drugs to achieve target therapeutic serum urate levels. Reaching target serum urate levels is associated with improvement in clinical outcomes, including a reduction of acute inflammation episodes, resolution of tophi, and improvement in health-related quality of life perception.A number of urate-lowering drugs are available but a number of patients fail to achieve or maintain therapeutic serum urate levels and go on to develop refractory chronic gout. For such patients, efforts have been made to develop new treatments (e.g., febuxostat or pegloticase).This review intends to increase the awareness of gout as a chronic deposition disease, and show that efforts should be made to properly control serum urate levels in order to achieve complete disappearance of urate crystal deposition.

  10. Prescribing clozapine and rifampicin: clinical impact of their interaction

    Parker, Caroline

    2016-01-01

    The predictable pharmacokinetic drug interaction between clozapine and rifampicin is listed in most standard reference texts but little detail is given or emphasis on its clinical significance. The interaction is based on theoretical knowledge of both drugs; to date just two case reports have been published. This article describes a third case demonstrating the significance of this interaction. This was potentially devastating for the patient who required an extended psychiatric admission. The enzyme induction was so potent that the dose of clozapine had to be increased approximately sixfold. Careful management of this significant interaction is essential for effective patient care.

    This article reports long-term infection and treatment failure in 18 symptomatic individuals infected with Blastocystis spp. Patients were initially treated with either metronidazole, iodoquinol or triple combination therapy consisting of nitazoxanide, furazolidone and secnidazole. Following treatment, resolution of clinical symptoms did not occur and follow-up testing revealed ongoing infection with the same subtype. Patients then underwent secondary treatment with a variety of antimicrobial agents but remained symptomatic with Blastocystis spp. still present in faeces. Sequencing of the SSU rDNA was completed on all isolates and four subtypes were identified in this group: ST1, ST3, ST4 and ST5. This study highlights the lack of efficacy of several commonly used antimicrobial regimens in the treatment of Blastocystis and the chronic nature of some infections. It also demonstrates the need for further research into treatment options for Blastocystis infection. PMID:24243286

    PubMed

    Ruszkiewicz, Cezary B

    2005-01-01

    The most frequent cause underlying the chronic lower extremities ischaemia is atheromatosis. As the basic symptom of the disease, intermittent claudication exerts essential impact upon the state of patient's health as it causes the limitation or the loss of the ability of unassisted walking and, effectively, also the deterioration of the quality of his or her life. The discovery of the etiopathogenesis of atheromatosis and correct assessment of risk factors involved are the elementary conditions of proper administering of pharmacological treatment as well as the basis for adequate planning of necessary prophylactic steps. In such cases, the diagnostic process ought to involve obtaining data from the patient's medical history and his or her physical examination, as well as determining his or her ankle-brachial index (ABI) and information derived from ultrasonographic examination performed at non-invasive diagnostics laboratory. The resultant treatment ought to focus on the improvement of the patient's functional efficiency. Before the necessity of surgical treatment is considered it is recommended to determine a plan for conservative treatment. Adequate diagnosis combined with an early commencement of conservative treatment in the cases of chronic lower extremities ischaemia frequently prove effective in arresting the development of the disease and, consequently, render invasive treatment unnecessary--thus resulting in the improvement of patient's quality of life.

Moderately good relief of pain was obtained with a combination of phenothiazines (especially pericyazine), antidepressant drugs and antihistamines. The theoretical implications of this are discussed and it is suggested that the drugs in question act partly by virtue of an effect on the multisynaptic neuronal systems whose activities are related to the experience of pain.

    Presented herein is experience in diagnosis and treatment of chronic diseases of lower-limb veins in a total of 242 children and adolescents. The authors used CEAP classification; C1 class was more often encountered in children. Treatment included surgical interventions, sclerotherapy, laser coagulation of pathological veins of lower extremities. Therapeutic outcomes were satisfactory in all patients, with no complications observed. It was determined that in paediatric phlebological practice prevailing are class C1 chronic venous diseases; characteristic is high concern of both the patient and parents. A timely commenced conservative program of treatment for children makes it possible to improve quality of life in class C1 and C2 chronic venous diseases. Laser coagulation of varicose saphenous veins of lower limbs in children makes it possible to remove pathological vessels, significantly improving quality of life of patients and shortening the terms of hospitalization twofold. Application of transcutaneous laser coagulation (Nd:YAG, 1064 nm) and microfoam sclerotherapy in children makes it possible to completely remove class C1 varicose veins, improving quality of life.

    The purposes of this systematic/critical review are: 1) to identify studies on the effects of exercise on chronic insomnia and sleep complaints in middle-aged and older adults and to compare the results of exercise with those obtained with hypnotic medications and 2) to discuss potential mechanisms by which exercise could promote sleep in insomniac patients. We identified studies from 1983 through 2011 using MEDLINE, SCOPUS and Web of Science. For systematic analyses, only studies assessing the chronic effects of exercise on sleep in people with sleep complaints or chronic insomnia were considered. We used the following keywords when searching for articles: insomnia, sleep, sleep complaints, exercise and physical activity. For a critical review, studies were selected on the effects of exercise and possible mechanisms that may explain the effects of exercise on insomnia. We identified five studies that met our inclusion criteria for systematic review. Exercise training is effective at decreasing sleep complaints and insomnia. Aerobic exercise has been more extensively studied, and its effects are similar to those observed after hypnotic medication use. Mechanisms are proposed to explain the effects of exercise on insomnia. There is additional documented evidence on the antidepressant and anti-anxiety effects of exercise. Exercise is effective to decrease sleep complaints and to treat chronic insomnia. Exercise presented similar results when compared with hypnotics; however, prospective studies comparing the effects of exercise with medical and non-medical treatments are warranted before including exercise as a first-line treatment for chronic insomnia are necessary.

    Migraine is the most common neurological disorder, and contributes to disability and large healthcare costs in the United States and the world. The treatment of migraine until recently has focused on medications, both abortive and prophylactic, but treatment of chronic migraine has been revolutionized with the introduction of botulinum toxin injection therapy. In this review, we explore the current understanding of migraine pathophysiology, and the evolution of the use of botulinum toxin therapy including proposed pathophysiological mechanisms through animal data. We also discuss the similarities and differences between three injection techniques.

    Objective Clozapine is the treatment of choice for refractory schizophrenia. The aim of this study was to compare the pharmacokinetics of the brand name (Clozaril) formulation and a generic formulation (Clzapine) of clozapine in Korean schizophrenic patients. Methods A prospective, randomized, crossover study was conducted to evaluate the steady-state pharmacokinetic profiles of Clozaril and Clzapine. Schizophrenic patients were randomized to receive either the brand name or generic formulation (100 mg twice daily) for 10 days, followed by the other formulation for 10 days. Plasma samples were collected on the last day of each treatment period. Results Twenty-two of 28 patients (78.6%) completed the study. The mean Cmax,ss values for Clzapine and Clozaril were 524.62 and 551.18 ng/mL, and the mean AUC0-12 values were 4479.90 hr·ng/mL and 4724.56 hr·ng/mL, respectively. The 90% CI values for the natural logarithmically transformed Cmax,ss and AUC0-12 ratios (Clzapine to Clozaril) after a single oral dose (100 mg) were 0.934 (0.849-1.028) and 0.936 (0.869-1.008), respectively. Five patients (20.8%) among 24 patients who took Clzapine reported 11 adverse events and six adverse events were reported by four patients (15.4%) among 26 who took Clozaril; there were no significant differences on physical examination or in vital signs, ECG, and laboratory tests between groups. Conclusion Generic clozapine (Clzapine) appears to be bioequivalent to brand name clozapine (Clozaril). PMID:26207129

    Background and aim The problem of antibiotic resistance is worldwide and affects many types of pathogens. This phenomenon has been growing for decades and nowadays we are faced with a wide range of worrisome pathogens that are becoming resistant and many pathogens that may soon be untreatable. The aim of this study was to determine the resistance and antibiotic treatment in chronic wounds of vascular origin. Methods We performed a cross sectional study on a sample of patients with chronic vascular wounds, hospitalized between October 2014 and August 2015, in the Clinic of Vascular Surgery in Trakia Hospital Stara Zagora. The statistical analysis of data was descriptive, considering the p value of ≤0.05, the threshold of statistical significance. Results In the group of 110 patients, the significantly most frequent chronic wound (p<0.001) was peripheral arteriopathy (47.3%, CI95%: 38.19–56.54). Among 159 strains, 30% of patients having multiple etiology, the species most frequently isolated were Staphylococcus aureus, E.coli, Enterococcus faecalis, Pseudomonas aeruginosa and Proteus mirabilis with a significant predominance (p<0.05) of the Gram negative (55.1%). The spectrum of strains resistance included the Beta-lactams (36.4%, p<0.001), Macrolides (20%), Tetracyclines (9.1%), Aminoglycosides (8.2%) and Fluoroquinolones (4.5%). Conclusions Gram negative microorganisms were the main isolates in patients with vascular chronic wound. Significantly predominant was the resistance to the beta-lactam antibiotics. PMID:27547055

  2. Combination treatment with interferon and ribavirin for chronic hepatitis C.

    Davis, G L

    Interferon was the first drug shown to be effective in patients with chronic hepatitis C, but initial treatment regimens achieved sustained loss of virus in only a small minority of patients. The combination of IFN with ribavirin now makes sustained response rates of 30% to 40% possible. This is quite a remarkable achievement for a pharmacologic treatment of a chronic viral infection. It is now reasonable to assume that early treatment and eradication of chronic hepatitis C might reduce the growing burden of hepatitis C and its complications on the healthcare system. Future researchers will strive to optimize combination treatment regimens. Longer treatment courses and intensified induction regimens using either daily dosing, high doses, or both may improve long-term response, but this remains speculative. Other forms of IFN may improve response or increase the ease of drug administration. Conjugation of biologic compounds to polyethylene glycol can result in significant prolongation of plasma half-life while maintaining the properties of the parent molecule. Some biologic properties may be altered, however, so pegylated IFN must continue to be evaluated in clinical trials. There is limited clinical data on other recombinant or natural interferons in combination with oral ribavirin, however, these may prove to be equally effective. Combinations of IFN with one or more other antiviral, anti-inflammatory, or immune modulatory agents will need to be studied. Although amantidine is not effective against hepatitis C as a single agent or in combination with IFN, the combination of IFN, ribavirin, and rimantidine has been shown to have antiviral activity superior to the IFN-ribavirin combination against influenza virus and possibly against HCV.

Availability of pain treatment facilities was scarce and the reported caseloads and wait times were generally high. A wide range of medical, physical, and psychological pain treatments were available. Most studies reported findings on the percentage of practitioners in different health care professions employed. Future studies should consider using more comprehensive search strategies to survey facilities, improving clarity on what is considered to be a pain treatment facility, and reporting on a consistent set of variables to provide a clear summary of the status of pain treatment facilities.

    Experiments have shown that chronic nicotine administration caused oxidative damage in various organs by increasing lipid peroxidation products and decreasing the activity of endogenous antioxidants. The aim of this study was to investigate the effects of taurine treatment on nicotine-induced oxidative changes in rat thoracic aorta and heart and to explore the possible mechanisms of action. Male Wistar albino rats (200-250 g) were injected with nicotine hydrogen bitartrate (0.6 mg/kg; i.p.) or saline for 21 days. Taurine was administered (50 mg/kg; i.p.) alone or along with nicotine injections. After decapitation, the thoracic aorta and heart tissues were excised. The aorta was used for in vitro contractility studies or stored along with the heart samples for the measurement of malondialdehyde (MDA) and glutathione (GSH) levels, myeloperoxidase (MPO) activity and collagen content. Tissue samples were also examined histologically. Serum samples were stored for the measurement of MDA, GSH and lactate dehydrogenase (LDH) activity. Chronic nicotine treatment impaired both the contraction and relaxation responses of the aortic rings to phenylephrine and acetylcholine, respectively. It increased lipid peroxidation, MPO levels and tissue collagen content of both aorta and heart samples. Taurine supplementation to nicotine-treated animals reversed the contractile dysfunction and restored the endogenous GSH levels and decreased high lipid peroxidation and MPO activities in both tissues. These data suggest that taurine supplementation effectively attenuates the oxidative damage because of chronic nicotine administration possibly by its antioxidant effects.

    Overproduction of oxidants (reactive oxygen species and reactive nitrogen species) in the human body is responsible for the pathogenesis of some diseases. The scavenging of these oxidants is thought to be an effective measure to depress the level of oxidative stress of organisms. It has been reported that intake of vegetables and fruits is inversely associated with the risk of many chronic diseases, and antioxidant phytochemicals in vegetables and fruits are considered to be responsible for these health benefits. Antioxidant phytochemicals can be found in many foods and medicinal plants, and play an important role in the prevention and treatment of chronic diseases caused by oxidative stress. They often possess strong antioxidant and free radical scavenging abilities, as well as anti-inflammatory action, which are also the basis of other bioactivities and health benefits, such as anticancer, anti-aging, and protective action for cardiovascular diseases, diabetes mellitus, obesity and neurodegenerative diseases.

    Introduction: Data on effect of clozapine on metabolic syndrome in adolescent patients with psychosis are limited. This study aimed to evaluate the prevalence and incidence of metabolic syndrome in children and adolescents with psychotic disorders prior to clozapine and while receiving clozapine. Secondary aims were to study the effectiveness and side effect profile of clozapine. Materials and Methods: Thirteen child and adolescent patients were evaluated at baseline, 3 months, and a follow-up beyond 6 months. Assessments were made for metabolic profile, effectiveness by positive and negative syndrome scale (PANSS), and side effects. Results: Prior to starting of clozapine, the prevalence of metabolic syndrome was 23%. After 3 months on clozapine, 38.5% (5/13) patients fulfilled criteria of metabolic syndrome and further on follow-up beyond 6 months (with last observation carried forward) 46.2% (6/13) had developed metabolic syndrome. There was a significant reduction in PANSS scores at 3 months and follow-up more so in those who developed metabolic syndrome at 3 months. Among the other side effects, hypersalivation was the most common side effect (100%) followed by sedation (69%). Conclusion: Half the prevalence of metabolic syndrome in adolescents on clozapine can be attributed to other factors prior to starting of clozapine, and another half can be attributed to clozapine. Clozapine is effective in an adolescent population. PMID:27335518

  9. Individual changes in clozapine levels after smoking cessation: results and a predictive model.

    Published reports document 20-40% lower mean serum clozapine concentrations in smokers compared with nonsmokers due to enzyme induction. Despite the increase in nonsmoking psychiatric facilities in the United States, previous studies have not tracked individual changes in serum clozapine levels after smoking cessation. Clozapine level changes were analyzed in 11 patients at Oregon State Hospital who were on stable clozapine doses, before and after implementation of a hospital-wide nonsmoking policy. A mean increase in clozapine levels of 71.9% (442.4 ng/ml +/- 598.8 ng/ml) occurred upon smoking cessation (p < .034) from a baseline level of 550.2 ng/ml (+/- 160.18 ng/ml). One serious adverse event, aspiration pneumonia, was associated with a nonsmoking serum clozapine level of 3066 ng/ml. Elimination of statistically extreme results generated a mean increase of 57.4 % or 284.1 ng/ml (+/- 105.2 ng/ml) for the remaining cases (p < .001) and permitted construction of a linear model which explains 80.9% of changes in clozapine levels upon smoking cessation (F = 34.9;p = .001): clozapine level as nonsmoker = 45.3 + 1.474 (clozapine level as smoker). These findings suggest that significant increases in clozapine levels upon smoking cessation may be predicted by use of a model. Those with high baseline levels should be monitored for serious adverse events. PMID:11763003

    Rehospitalization is an important outcome of drug effectiveness in schizophrenia. In this study, the hypothesis that clozapine and some second generation antipsychotics (SGA) were superior to first generation antipsychotics (FGA) in preventing rehospitalization of patients with schizophrenia discharged from a university hospital in Brazil was tested. A retrospective observational study was conducted designed to evaluate time to rehospitalization of patients with schizophrenia discharged on a regimen of oral FGA, depot FGA, risperidone, olanzapine and amisulpride, other SGA, or clozapine, during a three-year follow-up period. Risk factors associated with rehospitalization were examined. Of the 464 patients with schizophrenia discharged from hospital, 242 met criteria for study entry. Higher rehospitalization rates were observed in patients treated with depot FGA (30%), risperidone (30%) and other SGA groups (28.5%), respectively. Clozapine was significantly associated with lower rehospitalization risk compared with risperidone. The risk of rehospitalization in patients on olanzapine and amisulpride, and oral FGA, was similar to that of patients in use of clozapine. These results however, are limited by the heterogeneity of illness severity across the groups. PMID:21596442

    The development and evaluation of antiviral agents through carefully designed clinical trials over the last 25 years have heralded a new dawn in the treatment of patients chronically infected with the hepatitis B and C viruses, but not so for the D virus (HBV, HCV, and HDV). The introduction of direct acting antivirals (DDAs) for the treatment of HBV carriers has permitted the long-term use of these compounds for the continuous suppression of viral replication, whilst in the case of HCV in combination with the standard of care [SOC, pegylated interferon (PegIFN), and ribavirin] sustained virological responses (SVRs) have been achieved with increasing frequency. Progress in the case of HDV has been slow and lacking in significant breakthroughs.This paper aims to summarise the current state of play in treatment approaches for chonic viral hepatitis patients and future perspectives.

    Long-term chronic diseases have a high mortality rate around the world, affecting both genders equally. Despite improvements in the diagnosis and treatment of various health problems, lack of treatment compliance remains an obstacle to improving health and patient quality of life, and it carries a high associated socio-healthcare cost. The objectives of this study were to develop the concept of «therapeutic adherence», which includes both pharmacological compliance as well as non-pharmacological (level of agreement and patient involvement, lifestyle changes, etc.) treatments. The study also aimed to establish the clinical and socio-health impact of non-compliance, the reasons for non-compliance, and methods and strategies to improve compliance. The results of this study support therapeutic adherence as an essential goal of the healthcare system that encompasses all stakeholders involved in patient health.

    Chronic migraine (CM) is a common and disabling disorder that remains underdiagnosed and poorly treated. Significant unmet therapeutic needs add to the burden of this disorder; even when CM is recognized, effective treatment options are limited and randomized controlled trials supporting the use of various preventive medications are sparse. In this review, we discuss the available options for CM treatment. Currently the only FDA-approved treatment for CM prevention is onabotulinumtoxinA. Two double-blind studies have demonstrated the efficacy of topiramate for CM prevention, but it is not FDA-approved for this indication. Treatments in development for migraine will also be reviewed. Advancements in the understanding of migraine pathogenesis have identified new targets for both acute and preventive treatment and have engendered the development of targeted and mechanism-based therapies. The need for more effective treatment for CM patients, which has long since been identified, is now being addressed. Several of the emerging treatments for migraine prevention are under investigation specifically for CM or high-frequency episodic migraine.

    Objective. To describe the antiviral treatment patterns for chronic hepatitis B (CHB) among pregnant and nonpregnant women. Methods. Using 2011 MarketScan claims, we calculated the rates of antiviral treatment among women (aged 10–50 years) with CHB. We described the pattern of antiviral treatment during pregnancy and ≥1 month after delivery. Results. We identified 6274 women with CHB during 2011. Among these, 64 of 507 (12.6%) pregnant women and 1151 of 5767 (20.0%) nonpregnant women received antiviral treatment (P < 0.01). Pregnant women were most commonly prescribed tenofovir (73.4%) and lamivudine (21.9%); nonpregnant women were most commonly prescribed tenofovir (50.2%) and entecavir (41.3%) (P < 0.01). Among 48 treated pregnant women with an identifiable delivery date, 16 (33.3%) were prescribed an antiviral before pregnancy and continued treatment for at least one month after delivery; 14 (29.2%) started treatment during the third trimester and continued at least one month after delivery. Conclusion. Among this insured population, pregnant women with CHB received an antiviral significantly less often than nonpregnant women. The most common antiviral prescribed for pregnant women was tenofovir. These data provide a baseline for assessing changes in treatment patterns with anticipated increased use of antivirals to prevent breakthrough perinatal hepatitis B virus infection. PMID:25548510

    2009-01-01

    Chronic myeloid leukemia (CML) is a myeloproliferative disorder characterized by clonal expansion of pleuripotent hematopoetic stem cells. The incidence of CML is 1 to 2 cases per 100,000 people per year; in the Western Hemisphere, CML accounts for 15% of leukemias in adults. Discovery of the specific karyotypic abnormality of the Philadelphia (Ph) chromosome in the pathogenesis of CML has led to a better understanding of the disease and hence to an advancement of targeted therapeutics. Availability of imatinib as an accepted targeted therapy in newly diagnosed patients has changed the treatment paradigm in CML. The majority of CML patients in chronic phase achieve excellent and durable responses with standard-dose imatinib. Mechanisms of primary and secondary resistance to imatinib in CML have been extensively studied and newer tyrosine kinase inhibitors are now being evaluated for clinical use. It is important that at any time the CML treatment and response remain optimal and thus patients on imatinib require continuous monitoring for early detection of resistance. This review will discuss the treatment and guidelines for monitoring CML patients in the imatinib era. PMID:20616895

    Background: Insomnia is the most common sleep disorder that reduces quality of life. Objectives: Due to side effects of hypnotic drug and the increasing demand for alternative medicine substitutes, violet oil (VO) was used in this study. VO is a known medication in Iranian traditional medicine that induces sleep in insomniac patients. Patients and Methods: This study was conducted as an experimental pretest-posttest evaluation on VO efficacy in 50 patients with chronic insomnia in Iranian Traditional Medicine Clinic of Mashhad University of Medical Sciences, Mashhad, Iran. Treatment consisted of intranasal drop of VO, two drops containing 66 mg of VO in each nostril nightly before sleeping for one month. All patients were asked to complete an Insomnia Severity Index (ISI) questionnaire before the start of the trial and after one month of treatment. Results: Improvements in sleep and ISI scores were significantly greater in patients after a month receiving VO drop in comparison with before starting treatment (P < 0.05). A few patients reported some complications about VO consumption, most of which were mild and no serious adverse event was encountered. Conclusions: VO can be presented as a safe, well-tolerated, and effective herbal preparation in patients with chronic insomnia. PMID:25763239

    The binding of 11C-labelled clozapine in the brain was studied in three drug-free schizophrenic patients and in three healthy volunteers. High radioactivities were found in the striatum and in the frontal cortex. The rate constant k3, which is proportional to receptor association rate and the number of receptors, was lower in the frontal cortex compared to the striatum. No obvious difference between the two brain areas was seen for the dissociation rate constant from the receptors (k4). Two schizophrenic patients were reexamined after pretreatment with haloperidol, one after 6 weeks of treatment with a low oral dose, the other one after an IV injection 1 h before 11C-clozapine was given. After haloperidol pretreatment, the binding of 11C-clozapine in striatum and frontal cortex was reduced, more pronounced in the striatum, indicating competition for D-2 dopamine binding sites. Our finding indicates that clozapine has an affinity for a receptor population in the frontal cortex that is predominantly not of the dopamine-D2 type. This feature might be of importance for the unique clinical profile of the drug.

    Thermal therapy using far-infrared ray dry sauna was performed for patients with chronic fatigue syndrome (CFS). Symptoms such as fatigue, pain, and low-grade fever were dramatically improved on two patients. And prednisolone administration was discontinued and became socially rehabilitated 6 months after discharge. On other 11 patients with CFS, physical symptoms such as fatigue and pain improved, too. Furthermore, we reported that repeated thermal therapy had relaxation effect and diminishes appetite loss and subjective complaints in mildly depressed patients. These results suggest that repeated thermal therapy may be a promising method for the treatment of CFS.

  20. Approach to the Treatment of Chronic Metabolic Acidosis in CKD.

    PubMed

    2016-04-01

    Chronic metabolic acidosis is not uncommon in patients with chronic kidney disease (CKD). Clinical practice guidelines suggest that clinicians administer alkali to maintain serum bicarbonate level at a minimum of 22 mEq/L to prevent the effects of acidosis on bone demineralization and protein catabolism. Small interventional studies support the notion that correcting acidosis slows CKD progression as well. Furthermore, alkaline therapy in persons with CKD and normal bicarbonate levels may also preserve kidney function. Observational studies suggest that targeting a serum bicarbonate level near 28 mEq/L may improve clinical outcomes above and beyond targeting a value ≥ 22 mEq/L, yet values > 26 mEq/L have been reported to be associated with incident heart failure and mortality in the CRIC (Chronic Renal Insufficiency Cohort) Study. Furthermore, correcting acidosis may provoke vascular calcification. This teaching case discusses several uncertainties regarding the management of acidosis in CKD, such as when to initiate alkali treatment, potential side effects of alkali, and the optimum serum bicarbonate level based on current evidence in CKD. Suggestions regarding the maximum sodium bicarbonate dose to administer to patients with CKD to achieve the target serum bicarbonate concentration are offered.

    The introduction of second-generation tyrosine-kinase inhibitors (TKIs) has generated a lively debate on the choice of first-line TKI in chronic phase, chronic myeloid leukemia (CML). Despite the TKIs have different efficacy and toxicity profiles, the planned use of two TKIs has never been investigated. We report on a phase 2 study that was designed to evaluate efficacy and safety of a treatment alternating nilotinib and imatinib, in newly diagnosed BCR-ABL1 positive, chronic phase, CML patients. One hundred twenty-three patients were enrolled. Median age was 56 years. The probabilities of achieving a complete cytogenetic response, a major molecular response, and a deep molecular response (MR 4.0) by 2 years were 93%, 87%, and 61%, respectively. The 5-year overall survival and progression-free survival were 89%. Response rates and survival are in the range of those reported with nilotinib alone. Moreover, we observed a relatively low rate of cardiovascular adverse events (5%). These data show that the different efficacy and toxicity profiles of TKIs could be favorably exploited by alternating their use. Am. J. Hematol. 91:617-622, 2016. © 2016 Wiley Periodicals, Inc.

    Chronic pain in children and adolescents is associated with major disruption to developmental experiences crucial to personal adjustment, quality of life, academic, vocational and social success. Caring for these patients involves understanding cognitive, affective, social and family dynamic factors associated with persistent pain syndromes. Evaluation and treatment necessitate a comprehensive multimodal approach including psychological and behavioral interventions that maximize return to more developmentally appropriate physical, academic and social activities. This article will provide an overview of major psychosocial factors impacting on pediatric pain and disability, propose an explanatory model for conceptualizing the development and maintenance of pain and functional disability in medically difficult-to-explain pain syndromes, and review representative evidence-based cognitive behavioral and systemic treatment approaches for improving functioning in this pediatric population.

    Venous ulcer of the lower extremity is a common vascular condition and is associated with decreased quality of life, reduced mobility, and social isolation. Treatment of chronic venous ulcer (CVU) includes compression therapy, debridement of the ulcer when necessary, and wound care. Collagen and antimicrobial dressings can improve the proportion of ulcers healed compared with compression alone. Acellular skin equivalents are not superior to compression, but cellular human skin equivalents can promote more rapid healing, particularly in patients with longstanding ulcers. Current vascular surgical practice is to eliminate documented reflux or obstruction in patients with CVU that have failed a 3-month period of compression dressing, debridement, and local wound care. We found that surgical treatment of the superficial venous system can decrease the time to healing of CVUs compared with compression therapy alone, but does not increase the proportion of ulcers healed.

    2011-01-01

    Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired, immune-mediated polyradiculoneuritis that is progressive or relapsing over a period of at least 8 weeks. Although the exact pathogenesis is unclear, it is thought to be mediated by both cellular and humoral immune reactions directed against the peripheral nerve myelin or axon. CIDP also involves spinal nerve roots. Early medical treatment of CIDP is important to prevent axonal loss. Only three treatment regimens for CIDP have demonstrated benefit in randomized, controlled studies: corticosteroids, plasma exchange, and intravenous immunoglobulins (IVIg). Approximately 25% of patients respond inadequately to corticosteroids, plasma exchange or IVIg. Large placebo-controlled trials with alternative immunosuppressive compounds, e.g. mycophenolate mofetil, cyclosporine, cyclophosphamide, or monoclonal antibodies, are lacking. PMID:21694819

    This study examined the ability of the Theory of Planned Behavior (TPB; Ajzen, 1985) and the Transtheoretical Model of Behavior Change (TTM; Prochaska & DiClemente, 1983) to explain adherence and attrition in an online treatment program for chronic insomnia. Responses to questionnaire measures of the TPB and TTM were used to predict adherence and dropout over the subsequent 5 weeks of treatment. Results showed that there was a 17% dropout rate and that perceived behavioral control, social support, and intention to complete the program were significantly associated with adherence to sleep hygiene homework. Attrition was predicted only by symptom severity and psychiatric comorbidity. Implications are that these models should be considered to maximize adherence. PMID:20582757

    Four patients with refractory or poorly responsive chronic progressive demyelinating polyneuropathy (CPDP) were treated with total lymphoid irradiation (total dose, 2000 rad) in an uncontrolled feasibility study. All patients had previously failed conventional therapy for CPDP, as well as other unconventional treatments. During a follow-up period of 7 to 12 months after total lymphoid irradiation, there was a profound and sustained suppression of the absolute lymphocyte count and in vitro lymphocyte function, as well as an increase in the ratio of Leu-2 to Leu-3 T cells in the blood. Three of the four patients demonstrated improvement in distal muscle strength, and this was associated with increased functional capabilities in two patients. In contrast, no clinical improvement in sensation was noted in any patient. Nerve conduction studies showed patchy improvement in three patients. The results of this preliminary uncontrolled study indicate that radiotherapy deserves further study in the treatment of CPDP.

High Alt Med Biol. 17:61-69, 2016.-Millions of people worldwide live at a high altitude, and a significant number are at risk of developing Chronic Mountain Sickness (CMS), a progressive incapacitating syndrome caused by lifelong exposure to hypoxia. CMS is characterized by severe symptomatic excessive erythrocytosis (EE; Hb ≥19 g/dL for women and Hb ≥21 g/dL for men) and accentuated hypoxemia, which are frequently associated with pulmonary hypertension. In advanced cases, the condition may evolve to cor pulmonale and congestive heart failure. Current knowledge indicates a genetic predisposition to develop CMS. However, there are important risk factors and comorbidities that may trigger and aggravate the condition. Thus, appropriate medical information on CMS is necessary to provide adequate diagnosis and healthcare to high-altitude inhabitants. After reviewing basic clinical aspects of CMS, including its definition, diagnosis, and common clinical findings, we discuss aspects of its etiology, and address its epidemiology, risk factors, and treatment.

    The adult brain retains a substantial capacity for synaptic reorganization, which includes a wide range of modifications from molecular to structural plasticity. Previous reports have demonstrated that the structural remodeling of excitatory neurons seems to occur in parallel to changes in GABAergic neurotransmission. The function of neuronal inhibitory networks can be modified through GABAA receptors, which have a binding site for benzodiazepines (BZ). Although BZs are among the most prescribed drugs, is not known whether they modify the structure and connectivity of pyramidal neurons. In the present study we wish to elucidate the impact of a chronic treatment of 21 days with diazepam (2mg/kg, ip), a BZ that acts as an agonist of GABAA receptors, on the structural plasticity of pyramidal neurons in the prefrontal cortex of adult mice. We have examined the density of dendritic spines and the density of axonal en passant boutons in the cingulate cortex. Although no significant changes were observed in their anxiety levels, animals treated with diazepam showed a decrease in the density of spines in the apical dendrites of pyramidal neurons. Most GFP-expressing en passant boutons in the upper layers of the cingulate cortex had an extracortical origin and no changes in their density were detected after diazepam treatment. These results indicate that the chronic potentiation of GABAergic synapses can induce the structural remodeling of postsynaptic elements in pyramidal neurons. PMID:26733301

    Family, school and the peer network each shape the chronic pain experience of the individual child, and each of these contexts also represents a domain of functioning often impaired by chronic pain. The goal of the present article is to summarize what is known about these bidirectional influences between children with pain and the social systems that surround them. Case reports that illustrate these complex, transactional forces and their ultimate impact on the child’s pain-related functioning are included. A case involving siblings participating in an intensive interdisciplinary program for functional restoration and pain rehabilitation highlights how parents change through this treatment approach and how this change is vital to the child’s outcomes. Another case involving a child undergoing intensive interdisciplinary treatment illustrates how school avoidance can be treated in the context of pain rehabilitation, resulting in successful return to the regular school environment. Finally, an acceptance and commitment therapy-focused group intervention for children with sickle cell disease and their parents demonstrates the benefits of peer contact as an element of the therapeutic intervention.

    2009-01-01

    The development of imatinib for the treatment of chronic myeloid leukemia (CML) has proven to be an example of medical success in the era of targeted therapy. However, imatinib resistance or intolerance occurs in a substantial number of patients. Additionally, patients who have progressed beyond the chronic phase of CML do relatively poorly with imatinib therapy. Mechanisms of imatinib resistance include BCR-ABL point mutations resulting in decreased imatinib binding, as well as mutation-independent causes of resistance such as SRC family kinase dysregulation, BCR-ABL gene amplification, drug influx/efflux mechanisms and other poorly understood processes. The options for therapy in these patients include stem cell transplantation, imatinib dose escalation as well as the use of second-generation tyrosine kinase inhibitors. Dasatinib is a second-generation multi-kinase inhibitor with several theoretical and mechanistic advantages over imatinib. Moreover, several studies have evaluated dasatinib in patients who have progressed on imatinib therapy with encouraging results. Other novel agents such as mTOR inhibitors, bosutinib and INNO 406 have also shown promise in this setting. Although treatment options have increased, the choice of second-line therapy in patients with CML is influenced by concerns surrounding the duration of response as well as toxicity. Consequently, there is no agreed upon optimal second-line agent. This paper reviews the current data and attempts to address these issues. PMID:19707409

    Family, school and the peer network each shape the chronic pain experience of the individual child, and each of these contexts also represents a domain of functioning often impaired by chronic pain. The goal of the present article is to summarize what is known about these bidirectional influences between children with pain and the social systems that surround them. Case reports that illustrate these complex, transactional forces and their ultimate impact on the child's pain-related functioning are included. A case involving siblings participating in an intensive interdisciplinary program for functional restoration and pain rehabilitation highlights how parents change through this treatment approach and how this change is vital to the child's outcomes. Another case involving a child undergoing intensive interdisciplinary treatment illustrates how school avoidance can be treated in the context of pain rehabilitation, resulting in successful return to the regular school environment. Finally, an acceptance and commitment therapy-focused group intervention for children with sickle cell disease and their parents demonstrates the benefits of peer contact as an element of the therapeutic intervention.

    Purpose: To evaluate the clinical and radiological long-term results of recanalization of chronic occluded iliac arteries with balloon angioplasty and stent placement.Methods: Sixty-nine occluded iliac arteries (mean length 8.1 cm; range 4-16 cm) in 67 patients were treated by percutaneous transluminal angioplasty and stent placement. Evaluations included clinical assesment according to Fontaine stages, Doppler examinations with ankle-brachial index (ABI) and bilateral lower extremity arteriograms. Wallstent and Cragg vascular stents were inserted for iliac artery recanalization under local anesthesia. Follow-up lasted 1-83 months (mean 29.5 months).Results: Technical success rate was 97.1% (67 of 69). The mean ABI increased from 0.46 to 0.85 within 30 days after treatment and was 0.83 at the most recent follow-up. Mean hospitalization time was 2 days and major complications included arterial thrombosis (3%), arterial rupture (3%) and distal embolization (1%). During follow-up 6% stenosis and 9% thrombosis of the stents were observed. Clinical improvement occurred in 92% of patients. Primary and secondary patency rates were 75% and 95%, respectively.Conclusion: The long-term patency rates and clinical benefits suggest that percutaneous endovascular revascularization with metallic stents is a safe and effective treatment for patients with chronic iliac artery occlusion.

    Abstract Villafuerte, Francisco C., and Noemí Corante. Chronic mountain sickness: clinical aspects, etiology, management, and treatment. High Alt Med Biol. 17:61–69, 2016.—Millions of people worldwide live at a high altitude, and a significant number are at risk of developing Chronic Mountain Sickness (CMS), a progressive incapacitating syndrome caused by lifelong exposure to hypoxia. CMS is characterized by severe symptomatic excessive erythrocytosis (EE; Hb ≥19 g/dL for women and Hb ≥21 g/dL for men) and accentuated hypoxemia, which are frequently associated with pulmonary hypertension. In advanced cases, the condition may evolve to cor pulmonale and congestive heart failure. Current knowledge indicates a genetic predisposition to develop CMS. However, there are important risk factors and comorbidities that may trigger and aggravate the condition. Thus, appropriate medical information on CMS is necessary to provide adequate diagnosis and healthcare to high-altitude inhabitants. After reviewing basic clinical aspects of CMS, including its definition, diagnosis, and common clinical findings, we discuss aspects of its etiology, and address its epidemiology, risk factors, and treatment.

    Limits of treatment in chronic inflammatory demyelinating poly(radiculo)neuropathies (CIDP) patients are better known thanks to recent Cochrane reviews. (1) Randomized controlled trials have only focused on short-term effects, but most patients need long-term therapy, (2) There are three proven effective treatments available (prednisone; intravenous immunoglobulin or IVIg and plasma exchange or PE) which are useful in more than 60 p. 100 of patients, (3) New open studies indicated possible efficacy for mycophenolate, rituximab, etanercept, ciclosporine and interferons, and (4) Whether CIDP variants need specific treatment is still unknown. Many CIDP patients need treatment for years. The fear of side effects during long-term steroid treatment, the high costs of IVIg, the necessity for specialized equipment and the invasive nature of PE, are important factors determining the choice for one of these treatments. In most up-to-date treatment options, patients are initially treated with IVIg at a dosage of 2 g/kg administered for 25 days, clinical improvement can be judged within 10 days. The percentage of patients responding seems to be approximately 70 percent, with a very high chance (approximately 85 percent) that repeated administration of IVIg will be necessary, explaining why most neurologists add an immunosuppressive drug at this stage, but there is no consensus concerning the best drug to be used. Combinations of drugs are most likely to be useful in the next future, using IVIg, prednisone, and a immunosuppressor agent, such as mycophenolate, rituximab, etanercept, or ciclosporine. General measures to rehabilitate patients and to manage symptoms like fatigue and other residual findings are important.

    Recent evidence suggests that polyamines putrescine, spermidine and spermine are essential in maintaining normal cellular function. The present study investigated the effects of chronic treatment of difluoromethylornithine (DFMO, 3% in drinking water), a potent inhibitor of putrescine synthesis, for 54 consecutive days on animals'behavior and neurochemical levels in the CA1, CA2/3 and dentate gyrus sub-regions of the hippocampus and the prefrontal cortex. The DFMO group showed performance impairments in the place navigation and the probe test conducted 24 h after the training in the reference memory version of the water maze task, but not in the elevated plus maze, open field, object recognition, cued navigation and the working memory version of the water maze task when compared to the control group (drinking water only). DFMO treatment resulted in approximately 80-90% and 20% of reductions in the putrescine and spermidine levels, respectively, in the four brain regions examined, and a small reduction in agmatine level in the CA2/3, with no effects on spermine, glutamate and γ-aminobutyrate. The DFMO group showed decreased body weight relative to the control one. However, there were no significant differences between groups in the normalized brain, kidney and liver weights. The present study demonstrates that chronic treatment of DFMO depletes putrescine and decreases spermidine levels in the brain, inhibits growth, and impairs spatial learning and memory in the reference memory version of the water maze specifically. These findings merit further investigation to fully understand the functional role of endogenous polyamines in learning and memory.

    We evaluated immediate and long-term results of percutaneous transluminal angioplasty (PTA) and stent placement to treat stenotic and occluded arteries in patients with chronic mesenteric ischemia. Fourteen patients were treated by 3 exclusive celiac artery (CA) PTAs (2 stentings), 3 cases with both Superior Mesenteric Artery (SMA) and CA angioplasties, and 8 exclusive SMA angioplasties (3 stentings). Eleven patients had atheromatous stenoses with one case of an early onset atheroma in an HIV patient with antiphospholipid syndrome. The other etiologies of mesenteric arterial lesions were Takayashu arteritis (2 cases) and a postradiation stenoses (1 case). Technical success was achieved in all cases. Two major complications were observed: one hematoma and one false aneurysm occurring at the brachial puncture site (14.3%). An immediate clinical success was obtained in all patients. During a follow-up of 1-83 months (mean: 29 months), 11 patients were symptom free; 3 patients had recurrent pain; in one patient with inflammatory syndrome, pain relief was obtained with medical treatment; in 2 patients abdominal pain was due to restenosis 36 and 6 months after PTA, respectively. Restenosis was treated by PTA (postirradiation stenosis), and by surgical bypass (atheromatous stenosis). Percutaneous endovascular techniques are safe and accurate. They are an alternative to surgery in patients with chronic mesenteric ischemia due to short and proximal occlusive lesions of SMA and CA.

    Chronic radiation proctopathy (CRP) is a troublesome complication of pelvic radiotherapy. The most common presentation is rectal bleeding. CRP symptoms interfere with daily activities and decrease quality of life. Rectal bleeding management in patients with CRP represents a conundrum for practitioners. Medical therapy is ineffective in general and surgical approach has a high morbid-mortality. Endoscopy has a role in the diagnosis, staging and treatment of this disease. Currently available endoscopic modalities are formalin, potassium titanyl phosphate laser, neodymium:yttrium-aluminum-garnet laser, argon laser, bipolar electrocoagulation (BiCAP), heater probe, band ligation, cryotherapy, radiofrequency ablation and argon plasma coagulation (APC). Among these options, APC is the most promising. PMID:26981189

    Chronic perineal pain is the anorectal and perineal pain without underlying organic disease, anorectal or endopelvic, which has been excluded by careful physical examination, radiological and endoscopic investigations. A variety of neuromuscular disorders of the pelvic floor lead to the different pathological conditions such as anorectal incontinence, urinary incontinence and constipation of obstructed defecation, sexual dysfunction and pain syndromes. The most common functional disorders of the pelvic floor muscles, accompanied by perineal pain are levator ani syndrome, proctalgia fugax, myofascial syndrome and coccygodynia. In the diagnosis of these syndromes, contributing to a thorough history, physical examination, selected specialized investigations and the exclusion of organic disease with proctalgia is carried out. Accurate diagnosis of the syndromes helps in choosing an appropriate treatment and in avoiding unnecessary and ineffective surgical procedures, which often are performed in an attempt to alleviate the patient's symptoms.

    2011-06-01

    The prevalence of under nutrition in cirrhotic patients is 61% and it usually progresses as the disease becomes more advanced. The deterioration in the nutritional status and its associated metabolic derangements has raised doubts about the benefits of severe and prolonged protein restriction as a treatment for hepatic encephalopathy. However, the practice of dietary protein restriction for patients with liver cirrhosis is deeply embedded among medical practitioners and dietitians. To date, no solid conclusions may be drawn about the benefit of protein restriction. However, the negative effects of protein restriction are clear, that is, increased protein catabolism, the release of amino acids from the muscle, and possible worsening of hepatic encephalopathy. In conclusion, chronic protein restriction causes progressive and harmful protein depletion and must be avoided. PMID:22228881

    It is well documented in the current literature that chronic heart failure is often associated with cachexia, defined as involuntary weight loss of 5 % in 12 month or less. Clinical studies unraveled that the presence of cachexia decreases significantly mean survival of the patient. At the molecular level mainly myofibrillar proteins are degraded, although a reduced protein synthesis may also contribute to the loss of muscle mass. Endocrine factors clearly regulate muscle mass and function by influencing the normally precisely controlled balance between protein breakdown and protein synthesis The aim of the present article is to review the knowledge in the field with respect to the role of endocrine factors for the regulation of cachexia in patients with CHF and deduce treatment perspectives.

    Background People who inject drugs (PWID) constitute 10 million people globally with hepatitis C virus, including many opioid agonist treatment patients. Little data exist describing clinical outcomes for patients receiving HCV treatment with direct-acting antiviral agents (DAAs) in opioid agonist treatment settings. Methods In this retrospective observational study, we describe clinical outcomes for 50 genotype-1 patients receiving HCV treatment with triple therapy: telaprevir (n = 42) or boceprevir (n = 8) in combination with pegylated interferon and ribavirin on-site in an opioid agonist treatment program. Results Overall, 70% achieved an end of treatment response (ETR) and 62% achieved a sustained virological response (SVR). These treatment outcomes are nearly equivalent to previously published HCV outcomes shown in registration trials, despite high percentages of recent drug use prior to treatment (52%), ongoing drug use during treatment (45%) and psychiatric comorbidity (86%). Only 12% (n=6) discontinued antiviral treatment early for non-virological reasons. Four patients received a blood transfusion, and one discontinued telaprevir due to severe rash. Conclusions These data demonstrate that on-site HCV treatment with direct-acting antiviral agents is effective in opioid agonist treatment patients including patients who are actively using drugs. Future interferon-free regimens will likely be even more effective. Opioid agonist treatment programs represent an opportunity to safely and effectively treat chronic hepatitis C, and PWID should have unrestricted access to DAAs. PMID:26341685

    Abstract Chronic hepatitis C (CHC) disproportionately affects racial minorities in the United States (US). Although prior studies have reported lower treatment rates in Blacks than in Caucasians, the rates of other minorities remain understudied. We aimed to examine antiviral treatment rates by race and to evaluate the effect of other demographic, medical, and psychiatric factors on treatment rates. We performed a population-based study of adult CHC patients identified via ICD-9CM query from OptumInsight's Data Mart from January 2009 to December 2013. Antiviral treatment was defined by pharmaceutical claims for interferon and/or pegylated-interferon. A total of 73,665 insured patients were included: 51,282 Caucasians, 10,493 Blacks, 8679 Hispanics, and 3211 Asians. Caucasians had the highest treatment rate (10.7%) followed by Blacks (8.8%), Hispanics (8.8%), and Asians (7.9%, P < .001). Hispanics had the highest cirrhosis rates compared with Caucasians, Blacks, and Asians (20.7% vs 18.3%, 17.1%, and 14.3%, respectively). Caucasians were the most likely to have a psychiatric comorbidity (20.1%) and Blacks the most likely to have a medical comorbidity (44%). Asians were the least likely to have a psychiatric (6.4%) or medical comorbidity (26.9%). On multivariate analysis, racial minority was a significant predictor of nontreatment with odds ratios of 0.82 [confidence interval (CI): 0.74–0.90] for Blacks, 0.87 (CI: 0.78–0.96) for Hispanics, and 0.73 (CI: 0.62–0.86) for Asians versus Caucasians. Racial minorities had lower treatment rates than Caucasians. Despite fewer medical and psychiatric comorbidities and higher incomes and educational levels, Asians had the lowest treatment rates. Hispanics also had lower treatment rates than Caucasians despite having higher rates of cirrhosis. Future studies should aim to identify underlying racial-related barriers to hepatitis C virus treatment besides socioeconomic status and medical or psychiatric comorbidities

    Chronic spontaneous urticaria (CSU) is a disease with significant morbidity and relative prevalence that has important effects on the quality of life (QoL) of those who suffer from it. Omalizumab is a recombinant humanized anti-immunoglobulin E (IgE) antibody that binds to the Cε3 domain of the IgE heavy chain and prevents it from binding to its high-affinity receptor FcεRI. It has been largely studied in the field of asthma and is currently approved for the treatment of both adult and pediatric (children; >6-year-old) patients. In addition, in recent, well-controlled clinical trials in patients with CSU resistant to antihistamines, add-on therapy with subcutaneous omalizumab significantly reduced the severity of itching, and the number and size of hives, and increased patients' health-related QoL and the proportion of days free from angioedema compared with placebo, with an excellent tolerance. Thus, omalizumab is an effective and well-tolerated add-on therapy for patients with CSU who are symptomatic despite background therapy with H1 antihistamines. In this review, we cover the following points: epidemiology, pathogenesis, assessment of activity, impact on QoL, and treatment of CSU, and finally, we focus on omalizumab in the treatment of CSU including the pharmacokinetic properties and mechanism of action, and use in pregnant women, nursing infants, and children.

    Cocaine abuse and dependence is a major public health problem that continues to challenge medication-based treatment. Buspirone (Buspar) is a clinically available, non-benzodiazepine anxiolytic medication that acts on both serotonin and dopamine systems. In recent preclinical studies, acute buspirone treatment reduced cocaine self-administration at doses that did not also decrease food-reinforced behavior in rhesus monkeys (Bergman et al, 2012). The present study evaluated the effectiveness of chronic buspirone treatment on self-administration of cocaine and food. Five adult rhesus monkeys (Macaca mulatta) were trained to self-administer cocaine and food during four 1-h daily sessions under a second-order schedule of reinforcement (FR2 [VR 16:S]). Buspirone (0.32 and 0.56 mg/kg/h) was administered intravenously through one lumen of a double-lumen catheter every 20 min for 23 h each day for 7-10 consecutive days. Each buspirone treatment period was followed by saline control treatment until drug- and food-maintained responding returned to baseline levels. Buspirone significantly reduced responding maintained by cocaine, and shifted the dose-effect curve downwards. Buspirone had minimal effects on food-maintained responding. In cocaine discrimination studies, buspirone (0.1-0.32 mg/kg, IM) did not antagonize the discriminative stimulus and rate-altering effects of cocaine in four of six monkeys. These findings indicate that buspirone selectively attenuates the reinforcing effects of cocaine in a nonhuman primate model of cocaine self-administration, and has variable effects on cocaine discrimination.

    2000-03-21

    Background: Patients with chronic fatigue syndrome (CFS) have been faced with difficulties in diagnosis and lack of effective treatments. Anecdotal evidence suggests that use of alternative treatments may be common in these patients. Our primary objective was to compare the prevalence and patterns of alternative medicine use among twins who met the Centers for Disease Control and Prevention (CDC) CFS criteria to that of their non-CFS co-twins. Secondary goals were to assess how often alternative medicine use was discussed with physicians and the perceived benefit of these therapies. Methods: Sixty-three twin pairs discordant for CFS completed a survey about their use of 22 alternative therapies. Matched pair odds ratios and 95% confidence intervals were used to examine differences in the use between CFS twins and their non-CFS co-twins. Results: 91% of twins with CFS and 71% of non-CFS twins had used at least 1 alternative treatment in their lifetime. Twins with CFS were more likely to use homeopathy, mega-vitamins, herbal therapies, biofeedback, relaxation/meditation, guided imagery, massage therapy, energy healing, religious healing by others, and self-help groups than their non-CFS counterparts. A large proportion of all twins found alternative therapies helpful; however, only 42% of those with CFS and 23% of those without CFS discussed their use of alternative medicine with a physician. Conclusions: Individuals with CFS frequently used alternative medical treatments yet rarely communicated this use to their medical doctor. Future research should ascertain the usefulness of alternative practices in the management of CFS.

  10. Biofeedback treatment of chronic constipation: myths and misconceptions.

    PubMed

    Chiarioni, G

    2016-09-01

    Chronic constipation is a prevalent disorder with considerable impact on healthcare costs and quality of life. Most patients would respond to conservative measures in primary care. Patients with refractory constipation are commonly referred to dedicated centers for appropriate investigations and management. After testing, three main subtypes of constipation are commonly identified: normal colon transit, slow transit, and functional defecation disorders. The etiology of functional defecation disorders is consistent with maladaptive behavior, and biofeedback therapy has been considered a valuable treatment option. Being safe and only marginally invasive, retraining has been historically employed to manage all types of refractory constipation. There are a number of strongly held beliefs about biofeedback therapy that are not evidence-based. The aim of this review was to address these beliefs concerning protocols, efficacy, indications, and safety, with a special focus on the relevance of identifying patients with a functional defecation disorder who are ideal candidates for retraining. Randomized controlled trials support the effectiveness of biofeedback therapy for severe, refractory constipation due to functional defecation disorders. Limitations of the treatment are discussed, but biofeedback remains the safest option to successfully manage this hard-to-treat subtype of constipation. PMID:27450533

    INTRODUCTION Anal fissures are commonly encountered in routine colorectal practice. Developments in the pharmacological understanding of the internal anal sphincter have resulted in more conservative approaches towards treatment. Simple measures are often effective for early fissures. Glyceryl trinitrate is well established as a first-line pharmacological therapy. The roles of diltiazem and botulinum, particularly as rescue therapy, are not well understood. Surgery has a defined role and should not be discounted completely. METHODS Data were obtained from Medline publications citing ‘anal fissure’. Manual cross-referencing of salient articles was conducted. We have sought to highlight various controversies in the management of anal fissures. FINDINGS Acute fissures may heal spontaneously, although simple conservative measures are sufficient. Idiopathic chronic anal fissures need careful evaluation to decide what therapy is suitable. Pharmacological agents such as glyceryl trinitrate (GTN), diltiazem and botulinum toxin have been subjected to most scrutiny. Though practices in the UK vary, GTN or diltiazem would be suitable as first-line therapy with botulinum toxin used as rescue treatment. Sphincterotomy is indicated for unhealed fissures; fissurectomy has been revisited and advancement flaps have a role in patients in whom sphincter division is not suitable. PMID:17688717

    2016-02-01

    Pruritus is a common and often times difficult to treat symptom in many dermatologic and systemic diseases. For pruritus with an inflammatory or autoimmune origin, therapies such as topical corticosteroids and antihistamines are often initiated. However, in the case that these and additional systemic therapies are ineffective, thalidomide, an immunomodulator and neuromodulator, may be a useful alternative treatment. Considerable relief of chronic pruritus has been demonstrated with thalidomide in case reports, case series, and controlled trials. Double-blind controlled studies demonstrated thalidomide's efficacy as an antipruritic agent in patients with uremic pruritus, primary biliary cirrhosis, and prurigo nodularis. In case reports, case series, and open-label trials, thalidomide significantly reduced pruritus associated with conditions such as actinic prurigo and paraneoplastic pruritus. Because of variations in study design and evaluation of antipruritic effect, it is difficult to fully understand thalidomide's role based on the evidence described to date in the medical literature. In this review, we provide an overview of the reported findings and evaluate thalidomide's utility in managing refractory pruritus in the context of its adverse risk profile. We propose that thalidomide can be an alternative or combination antipruritic treatment for patients who do not obtain enough relief from conservative therapy.

    Chronic graft-versus-host disease (cGVHD) following allogeneic hematopoietic stem cell transplantation (HSCT) has emerged as a predominant complication following HSCT and has a distinct etiology. We and others have previously demonstrated that bortezomib, a proteasome inhibitor, can prevent but not treat acute GVHD in mice. To assess the effects of bortezomib on cGVHD, a mouse minor histocompatibility antigen-mismatched strain combination was used to mimic clinical cGVHD sclerodermatous pathogenesis and phenotype. Treatment of ongoing cGVHD with bortezomib ameliorated cutaneous lesions, which were also associated with a reduction in total numbers of germinal center B cells and lower B-cell activating factor gene expression levels in cutaneous tissues. Importantly, lymphoma-bearing mice receiving allogeneic HSCT with bortezomib preserved graft-versus-tumor (GVT) effects. Based on these animal studies, we initiated an intrapatient dose escalation clinical trial in patients with extensive steroid–intolerant, dependent, or resistant cGVHD. Marked clinical improvement was observed in patients, which was also associated with reductions of peripheral B cells and minimal toxicity. These results indicate that bortezomib can be of significant use in the treatment of cGVHD and may also allow for maintenance of GVT. This trial was registered at www.clinicaltrials.gov as #NCT01672229. PMID:25009225

    2010-01-01

    Background Chronic depressions represent a substantial part of depressive disorders and are associated with severe consequences. Several studies were performed addressing the effectiveness of psychotherapeutic, pharmacological, and combined treatments for chronic depressions. Yet, a systematic review comparing the effectiveness of multiple treatment options and considering all subtypes of chronic depressions is still missing. Methods/Design Aim of this project is to summarize empirical evidence on efficacy and effectiveness of treatments for chronic depression by means of a systematic review. The primary objectives of the study are to examine, which interventions are effective; to examine, if any differences in effectiveness between active treatment options exist; and to find possible treatment effect modifiers. Psychotherapeutic, pharmacological, and combined treatments will be considered as experimental interventions and no treatment, wait-list, psychological/pharmacological placebo, treatment as usual, and other active treatments will be seen as comparators. The population of patients will include adults with chronic major depression, dysthymia, double depression, or recurrent depression without complete remission between episodes. Outcomes of the analyses are depressive symptoms, associated consequences, adverse events, and study discontinuation. Only randomized controlled trials will be considered. Discussion Given the high prevalence and serious consequences of chronic depression and a considerable amount of existing primary studies addressing the effectiveness of different treatments the present systematic review may be of high relevance. Special attention will be given to the use of current methodological standards. Findings are likely to provide crucial information that may help clinicians to choose the appropriate treatment for chronically depressed patients. PMID:21092304

    Objectives: With growing evidence for the effectiveness of craniosacral therapy (CST) for pain management, the efficacy of CST remains unclear. This study therefore aimed at investigating CST in comparison with sham treatment in chronic nonspecific neck pain patients. Materials and Methods: A total of 54 blinded patients were randomized into either 8 weekly units of CST or light-touch sham treatment. Outcomes were assessed before and after treatment (week 8) and again 3 months later (week 20). The primary outcome was the pain intensity on a visual analog scale at week 8; secondary outcomes included pain on movement, pressure pain sensitivity, functional disability, health-related quality of life, well-being, anxiety, depression, stress perception, pain acceptance, body awareness, patients’ global impression of improvement, and safety. Results: In comparison with sham, CST patients reported significant and clinically relevant effects on pain intensity at week 8 (−21 mm group difference; 95% confidence interval, −32.6 to −9.4; P=0.001; d=1.02) and at week 20 (−16.8 mm group difference; 95% confidence interval, −27.5 to −6.1; P=0.003; d=0.88). Minimal clinically important differences in pain intensity at week 20 were reported by 78% within the CST group, whereas 48% even had substantial clinical benefit. Significant between-group differences at week 20 were also found for pain on movement, functional disability, physical quality of life, anxiety and patients’ global improvement. Pressure pain sensitivity and body awareness were significantly improved only at week 8. No serious adverse events were reported. Discussion: CST was both specifically effective and safe in reducing neck pain intensity and may improve functional disability and the quality of life up to 3 months after intervention.

    We tested the efficacy of azithromycin ophthalmic solution for the treatment of chronic mixed anterior blepharitis. The findings suggest that patients with chronic mixed anterior blepharitis can be more effectively treated with azithromycin ophthalmic solution than erythromycin ophthalmic ointment. Patients treated with azithromycin ophthalmic solution show an extraordinary clinical response with shorter treatment duration.

  17. Treatment seeking behaviour in southern Chinese elders with chronic orofacial pain: a qualitative study

    2014-01-01

    Background Chronic orofacial pain (OFP) is common in general adult populations worldwide. High levels of psychological distress and impaired coping abilities are common among Western people with chronic OFP but limited information was found in southern Chinese people. This study aimed to explore the perceptions and experiences of community dwelling elderly people with chronic OFP symptoms and their treatment seeking behaviour in Hong Kong. Methods An exploratory qualitative interview study was conducted. Elderly people experiencing chronic OFP symptoms were invited to take part in an individual semi-structured interview. A total of 25 semi-structured interviews were performed for 25 participants. Results Pertinent issues relating to the treatment seeking behaviour emerged from the interviews, many of which were inter-related and overlapping. They were organized into three major themes: (i) Impact of chronic OFP on daily life; (ii) Personal knowledge and feeling of chronic OFP; (iii) Management of chronic OFP. The participants were found to have the intention to seek professional treatment, but there were barriers which discouraged them continuing to seek professional treatment. They also received complementary treatment for chronic OFP, such as acupuncture, massage and “chi kung”. Moreover, a wide range self-management techniques were also mentioned. On the other hand, those who did not seek professional treatment for the chronic OFP claimed that they had accepted or adapted to the pain as part of their lives. Conclusions This qualitative study observed that elderly people affected by chronic OFP symptoms in Hong Kong sought many different ways to manage their pain including traditional and complementary approaches. The role of the dentist in dealing with chronic OFP is unclear. Multiple barriers exist to accessing care for chronic OFP. The findings may be used to inform future chronic OFP management strategies in Hong Kong. PMID:24460663

    Neurotransmitter amino acid levels were measured in select brain regions of rats and mice after chronic treatment with sublethal doses of sodium hydrosulfide (NaHS). Brainstem aspartate, glutamate, glutamine, taurine and GABA levels increased in chronically but not acutely saline-treated rats. These increases may have been due to stress from frequent handling, and were prevented by chronic NaHS treatment (7.5 mg/kg ip every 8 hr for 3 consecutive days). In contrast, aspartate, glutamate and glutamine increased in female but not in male ICR mouse brainstems after once daily treatment with 7.0 mg/kg NaHS for 5 consecutive days. These effects of NaHS may indicate chronic low level H2S neurotoxicity. Differences between chronic and acute treatments, female and male responses, and treatment paradigms may complicate interpretations of such toxicity studies.

    Background: Chronic migraine is a common, highly disabling, underdiagnosed and undertreated entity of migraine. It affects 0.9%–2.2% of the general adult population. The present paper overviews the preclinical and clinical data regarding the therapeutic effect of onabotulinumtoxinA in chronic migraineurs. Methods: A literature search was conducted in the database of PubMed up to 20 May 2015 for articles related to the pathomechanism of chronic migraine, the mode of action, and the efficacy, safety and tolerability of onabotulinumtoxinA for the preventive treatment of chronic migraine. Results: The pathomechanism of chronic migraine has not been fully elucidated. The mode of action of onabotulinumtoxinA in the treatment of chronic migraine is suggested to be related to the inhibition of the release of calcitonin gene-related peptide and substance P in the trigeminovascular system. Randomized clinical trials demonstrated that long-term onabotulinumtoxinA fixed-site and fixed-dose (155–195 U) intramuscular injection therapy was effective and well tolerated for the prophylactic treatment of chronic migraine. Conclusions: Chronic migraine is a highly devastating entity of migraine. Its exact pathomechanism is unrevealed. Two-third of chronic migraineurs do not receive proper preventive medication. Recent clinical studies revealed that onabotulinumtoxinA was an efficacious and safe treatment for chronic migraine. PMID:26193319

    Exercise training is an established method of treatment in patients with chronic heart failure (CHF), which is still underused in Poland. It has been shown to improve exercise tolerance, physical fitness, clinical status and probably prognosis. Mechanism of it's beneficial effects is under investigation, to answer the question, whether exercise training just reverses changes caused by decrease in physical activity or interferes with the catabolic factors involved in the pathogenesis of myopathy. According to "cytokine theory", progression of CHF is at least partly due to the inflammatory process with cytokines in it's center. In this context it is investigated whether exercise training has immunomodulatory effects. This paper reviews the role of inflammation in the pathogenesis of CHF. It is stressed that intensive exercise increases inflammation. In this context immunomodulatory effects of exercise training are discussed. Papers review effects of physical training, taken into consideration different forms of training, it's influence of different stages of inflammation and clinical status of patients. It is emphasized, that probably there are differences in training effects in relation to etiology of CHF. There are not many studies concerning these problems. It seems, based on their results that improvement of exercise capacity and clinical status after exercise training may be, at least partly, explained by decrease in inflammatory reaction. These papers contributes to better understanding of the role of inflammation in CHF and open a new scope of investigation asking new questions.

    By 2020 chronic obstructive pulmonary disease (COPD) will be the third leading cause of mortality and fifth leading cause of morbidity. Research over the past two decades has shed important insights on the pathobiology of COPD, leading to the development of novel drugs. In the past, symptomatic treatment with bronchodilators was the predominant focus of COPD management. With increased awareness of the importance of airway inflammation in COPD progression, there has been a shift in emphasis to drugs that attack various targets in the inflammatory cascade. These drugs include phosphodiesterase 4 inhibitors, leukotriene modifiers and TNF antagonists, which are poised to enter the COPD market in the very near future. Tyrosine kinase antagonists, inhibitors of NF-kappaB, neutrophil elastase inhibitors, chemokine antagonists, mucolytics and novel antibiotics are being evaluated for possible effectiveness in COPD. Many of these drugs may enter the COPD market within the next decade. This paper reviews the molecular rationale for these emerging drugs and their potential efficacy in COPD.

  3. Hsp90 Inhibitors for the Treatment of Chronic Myeloid Leukemia

    PubMed Central

    Khajapeer, Kalubai Vari; Baskaran, Rajasekaran

    2015-01-01

    Chronic myeloid leukemia (CML) is a hematological malignancy that arises due to reciprocal translocation of 3′ sequences from c-Abelson (ABL) protooncogene of chromosome 9 with 5′ sequence of truncated break point cluster region (BCR) on chromosome 22. BCR-ABL is a functional oncoprotein p210 that exhibits constitutively activated tyrosine kinase causing genomic alteration of hematopoietic stem cells. BCR-ABL specific tyrosine kinase inhibitors (TKIs) successfully block CML progression. However, drug resistance owing to BCR-ABL mutations and overexpression is still an issue. Heat-shock proteins (Hsps) function as molecular chaperones facilitating proper folding of nascent polypeptides. Their increased expression under stressful conditions protects cells by stabilizing unfolded or misfolded peptides. Hsp90 is the major mammalian protein and is required by BCR-ABL for stabilization and maturation. Hsp90 inhibitors destabilize the binding of BCR-ABL protein thus leading to the formation of heteroprotein complex that is eventually degraded by the ubiquitin-proteasome pathway. Results of many novel Hsp90 inhibitors that have entered into various clinical trials are encouraging. The present review targets the current development in the CML treatment by availing Hsp90 specific inhibitors. PMID:26770832

    Chronic lymphocytic leukemia (CLL) is the most frequent type of hematological cancer in the Western World. An accumulation of leukemic cells in peripheral blood of patients is a result of apoptosis disturbances as well as an increase in germinal centers CLL cell proliferation. The differences between CLL patients in the course and response to therapy reflects personal variability between patients in their genetic material. It was documented that many sufferers from CLL are over 60 years old, and because of many countries' population obsolescence this type of leukemia could become more frequent in the future. CLL remains incurable, and the therapy regimens available at present could induce even complete remissions, but finally a relapse of the disease. The etiology of this disease is still not known, but our understanding of the processes running in CLL cells has significantly increased. A number of new agents with potential of CLL cell elimination by apoptosis or autophagy were characterized. Some of them reflect potential in cell sensitization to standard therapy. The major challenge for the future is to develop targeted anti-cancer therapy and design the optimal personalized manner of CLL treatment. A special interest is focused on anti-cancer agents - natural substances of plant origin. This paper reviews chosen new anti-leukemic agents belonging to different drug-classes (new monoclonal antibodies or apoptosis-, BCR signaling- and cell cycle-related inhibitors, substances of plant origin) which are under intense investigation in preclinical studies and early clinical trials.

    2016-01-01

    Chronic cough is common in the population, and among some there is no evident medical explanation for the symptoms. Such a refractory or idiopathic cough is now often regarded as a neuropathic disease due to dysfunctional airway ion channels, though the knowledge in this field is still limited. Persistent coughing and a cough reflex easily triggered by irritating stimuli, often in combination with perceived dyspnea, are characteristics of this disease. The patients have impaired quality of life and often reduced work capacity, followed by social and economic consequences. Despite the large number of individuals suffering from such a persisting cough, there is an unmet clinical need for effective cough medicines. The cough treatment available today often has little or no effect. Adverse effects mostly follow centrally acting cough drugs comprised of morphine and codeine, which demands the physician's awareness. The possibilities of modulating airway transient receptor potential (TRP) ion channels may indicate new ways to treat the persistent cough "without a reason". The TRP ion channel vanilloid 1 (TRPV1) and the TRP melastin 8 (TRPM8) appear as two candidates in the search for cough therapy, both as single targets and in reciprocal interaction. PMID:27483288

    Chronic lymphocytic leukemia (CLL) is characterized by a highly variable clinical course. Among the biological features underlying this heterogeneity, genetic lesions and the mutational status of the immunoglobulin heavy chain variable genes (IGHV) are of importance. Therapeutic options in CLL have been considerably expanded during recent years. The combination of fludarabine, cyclophosphamide and rituximab (FCR) has become gold standard in the first-line treatment of physically fit patients. Bendamustine plus rituximab (BR) is currently being compared to FCR in studies and chlorambucil is still of relevance for elderly patients with comorbidities. Alemtuzumab is an alternative for high-risk patients (refractory CLL, 17p deletion, TP53 mutation). Allogeneic stem cell transplantation (allo-SCT) offers the only chance of cure but not without substantial mortality. Innovative approaches focus on individualized, targeted therapies. A number of novel agents are in clinical trials and show marked efficacy combined with good tolerability. This review provides an overview of the current therapeutic options and of promising novel approaches.

    With the discovery of Philadelphia chromosome, understanding of chronic myeloid leukemia (CML) pathobiology has tremendously increased. Development of tyrosine kinase inhibitors (TKI) targeting the BCR/ABL1 oncoprotein has changed the landscape of the disease. Today, the expected survival of CML patients, if properly managed, is likely to be similar to the general population. Imatinib is the first-approved TKI in CML treatment, and for several years, it was the only option in the frontline setting. Four years ago, second-generation TKIs (nilotinib and dasatinib) were approved as alternative frontline options. Now, clinicians are faced the challenge of making decision for which TKI to chose upfront. Second-generation TKIs have been demonstrated to induce deeper and faster responses compared to imatinib; however, none of three TKIs have been shown to have a clear survival advantage, they all are reasonable options. In contrast, when considering therapy in individual patients, the case may be stronger for a specific TKI. Co-morbidities of the patient and side effect profile of the TKI of interest should be an important consideration in decision making. At present, the cost nilotinib or dasatinib is not remarkably different from imatinib. However, patent for imatinib is expected to expire soon, and it will be available as a generic. Clinicians, then, need to weigh the advantages some patients gain with nilotinib or dasatinib in the frontline setting against the difference in cost. Whatever TKI is chosen as frontline, intolerance, non-compliance, or treatment failure should be recognized early as a prompt intervention increases the chance of achieving best possible response.

    Fourteen patients (7 male, 7 female, 22-63 years), classified as having chronic fatigue syndrome (CFS), but without concurrent major depression, significant sleepiness or use of psychoactive medication, completed a double-blind, placebo-controlled, crossover study of the effects of the selective wakefulness-promoting agent, modafinil (200 and 400mg/day). The treatment periods were each 20 days, with washout periods of 2 weeks. The primary aim was to determine effects on cognition and the secondary aim was to determine effects on self-ratings of fatigue, quality of life and mood. Modafinil had mixed effects in two cognitive tasks. In a test of sustained attention, treatment with 200mg reduced the latency to correctly detect sequences, but 400mg increased the number of missed targets. In a test of spatial planning, the 200mg dose resulted in a slower initial thinking time for the easiest part of the task, whereas 400mg reduced the initial thinking time for the hardest part of the test. Lastly, in a test of mental flexibility and one of motor speed, patients performed worse whilst on modafinil (400mg), compared with the placebo period. No effects were observed on the performance of other psychometric tests or on self-ratings of fatigue, quality of life or mood, but this may have been due to insufficient statistical power. It is discussed whether the limited and mixed cognitive effects that we observed could have occurred by chance, or whether a subgroup of CFS patients with daytime sleepiness would have shown greater benefits.

    Background: Preclinical and clinical data suggest that cannabidiol (CBD), a major non-psychotomimetic compound from Cannabis sativa, induces antipsychotic-like effects. However, the antipsychotic properties of repeated CBD treatment have been poorly investigated. Behavioral changes induced by repeated treatment with glutamate N-methyl-D-aspartate receptor (NMDAR) antagonists have been proposed as an animal model of schizophrenia-like signs. In the present study, we evaluated if repeated treatment with CBD would attenuate the behavioral and molecular modifications induced by chronic administration of one of these antagonists, MK-801. Methods: Male C57BL/6J mice received daily i.p. injections of MK-801 (0.1, 0.5, or 1mg/kg) for 14, 21, or 28 days. Twenty-four hours after the last injection, animals were submitted to the prepulse inhibition (PPI) test. After that, we investigated if repeated treatment with CBD (15, 30, and 60mg/kg) would attenuate the PPI impairment induced by chronic treatment with MK-801 (1mg/kg; 28 days). CBD treatment began on the 6th day after the start of MK-801 administration and continued until the end of the treatment. Immediately after the PPI, the mice brains were removed and processed to evaluate the molecular changes. We measured changes in FosB/ΔFosB and parvalbumin (PV) expression, a marker of neuronal activity and a calcium-binding protein expressed in a subclass of GABAergic interneurons, respectively. Changes in mRNA expression of the NMDAR GluN1 subunit gene (GRN1) were also evaluated. CBD effects were compared to those induced by the atypical antipsychotic clozapine. Results: MK-801 administration at the dose of 1mg/kg for 28 days impaired PPI responses. Chronic treatment with CBD (30 and 60mg/kg) attenuated PPI impairment. MK-801 treatment increased FosB/ΔFosB expression and decreased PV expression in the medial prefrontal cortex. A decreased mRNA level of GRN1 in the hippocampus was also observed. All the molecular changes were

    Hepatitis E, caused by hepatitis E virus (HEV) infection, usually leads to an acute clinical course, and is the most common diagnosis among cases of acute viral hepatitis. From 2008, there have been increasing reports of chronic HEV infection in immunocompromised patients such as organ transplant recipients. Without intervention with antiviral treatment, approximately 60% of HEV infections in organ transplant recipients evolve into chronic HEV infections. Of these chronic hepatitis E patients, 10% may develop liver fibrosis and progress to liver cirrhosis. This article reviews chronic HEV infection and treatment in organ transplant recipients.

    Chronic pain can be described as a syndrome or process of decompensation not unlike any other chronic disease or illness. As such, chronic pain patients are often difficult to work with because of the pervasive personal, social, emotional, and physical impact of the syndrome on their lives and the lives of their families. The pain curve was developed to be used as an educational instrument to assist patients in understanding the disease process, confronting denial, and self-diagnosing their illness. This curve now in use at our institution describes both the progression and the recovery of the illness. The pain curve is used as an educational tool to aid patients in addressing important recovery issues such as denial and the disease process, the progression of symptoms in a chronic illness, medication and alcohol use and abuse in the management of chronic pain, the impact on and from the family and the importance of peer support.

    Kurz et al. conducted the first study of the intra-individual variability of clozapine plasma concentrations but did not take into account the effect of smoking and co-medication. As patients were receiving varying doses, Kurz et al. standardized plasma levels by using a plasma level/dose/kg ratio. In 15 patients, the mean coefficient of variation (CV) was 53% (S.D. = 21). In this new study, plasma clozapine and norclozapine concentrations were measured every 2 weeks in 47 patients randomized to 100, 300, or 600 mg/day for 16-week double-blind clozapine trials under controlled conditions (stable smoking, limited co-medication and absence of caffeinated beverages). For 100, 300 and 600 mg/day, the respective mean CVs for plasma clozapine concentrations were 23% (S.D. = 14), 19% (S.D.= 11) and 18% (S.D. = 8). For the combined concentrations of clozapine and norclozapine, the respective mean CVs were 20% (S.D. = 13), 16% (S.D. = 9) and 15% (S.D. = 7). Under 100 mg/day, the mean CV for clozapine concentrations was significantly higher for heavy smokers than non-heavy smokers (32%, S.D. = 3 vs. 19%, S.D. = 8) (p = 0.03). Studies of CVs in other environments are needed. Clozapine CVs may be important in order to understand the importance of variations around the therapeutic range and to interpret drug interactions above the usual noise of measuring plasma concentrations.

We have used the EMBASE and MEDLINE databases, and we applied bibliometric indicators of production, as Price’s Law on the increase of scientific literature. We also calculated the participation index (PI) of the different countries. The bibliometric data have also been correlated with some social and health data from the 12 most productive countries in biomedicine and health sciences. In addition, 5607 original documents dealing with clozapine, published between 1970 and 2013, were downloaded. Our results state non-fulfilment of Price’s Law, with scientific production on clozapine showing linear growth (r = 0.8691, vs. r = 0.8478 after exponential adjustment). Seven of the 12 journals with the highest numbers of publications on clozapine have an Impact Factor > 2. Among the countries generating clozapine research, the most prominent is the USA (PI = 24.32), followed by the UK (PI = 6.27) and Germany (PI = 5.40). The differences among countries on clozapine research are significantly related to economic variables linked to research. The scientific interest in clozapine remains remarkable, although after the application of bibliometric indicators of production, a saturation point is evident in the growth of scientific literature on this topic.

    Migraine is a common neurological disorder, characterised by severe headaches. Epidemiological studies in the USA and Europe have identified a subgroup of migraine patients with chronic migraine. Chronic migraine is defined as ≥15 headache days per month for ≥3 months, in which ≥8 days of the month meet criteria for migraine with or without aura, or respond to treatment specifically for migraine. Chronic migraine is associated with a higher burden of disease, more severe psychiatric comorbidity, greater use of healthcare resources, and higher overall costs than episodic migraine (<15 headache days per month). There is a strong need to improve diagnosis and therapeutic treatment of chronic migraine. Primary care physicians, as well as hospital-based physicians, are integral to the identification and treatment of these patients. The latest epidemiological data, as well as treatment options for chronic migraine patients, are reviewed here.

    The chronic MPTP+probenecid treatment paradigm has been used to successfully model the neurochemical, neuropathological, and behavioral effects associated with Parkinson's disease. Here, adult male C57Bl/6 mice were injected ip with 25 mg/kg MPTP and 250 mg/kg probenecid (MPTPp) or saline twice weekly for a total of 10 injections. Behavioral assessments included motor coordination, grip strength, spatial learning/memory, locomotor activity, and anhedonia. Those assessments were repeated up to 8 weeks post-treatment. In a subsequent experiment, adult male mice were treated with saline or MPTPp as described above. One-half of each group was allowed access to 1% trehalose in the water bottle. Trehalose intake averaged 1.90-2.34 g/kg. Behavioral assessments included locomotor activity, olfaction, motor coordination, grip strength, and exploratory behavior. Those assessments were repeated 4 weeks post-treatment. The strongest MPTPp effect was hyperactivity as exhibited in the open field. This increased activity was apparent in both experiments and occurred at all time points post-treatment. Assessments of grip strength, water maze performance, olfaction, and exploratory behavior did not indicate MPTPp-related alterations. When the specifications for the motor coordination test were made somewhat easier in the second experiment, there were deficits exhibited by the MPTPp group, the MPTPp+trehalose group and the trehalose group. The addition of trehalose did not alleviate any of the MPTPp-induced behavioral alterations; however, trehalose treatment significantly attenuated the striatal decreases in DA, DOPAC, HVA and 5-HIAA. These results provide a more comprehensive description of the behavioral alterations resulting from the chronic MPTPp treatment regimen and suggest that trehalose at this concentration does not act as a complete neuroprotectant.

Trehalose intake averaged 1.90-2.34 g/kg. Behavioral assessments included locomotor activity, olfaction, motor coordination, grip strength, and exploratory behavior. Those assessments were repeated 4 weeks post-treatment. The strongest MPTPp effect was hyperactivity as exhibited in the open field. This increased activity was apparent in both experiments and occurred at all time points post-treatment. Assessments of grip strength, water maze performance, olfaction, and exploratory behavior did not indicate MPTPp-related alterations. When the specifications for the motor coordination test were made somewhat easier in the second experiment, there were deficits exhibited by the MPTPp group, the MPTPp+trehalose group and the trehalose group. The addition of trehalose did not alleviate any of the MPTPp-induced behavioral alterations; however, trehalose treatment significantly attenuated the striatal decreases in DA, DOPAC, HVA and 5-HIAA. These results provide a more comprehensive description of the behavioral alterations resulting from the chronic MPTPp treatment regimen and suggest that trehalose at this concentration does not act as a complete neuroprotectant.

    Some patients have persistence of profound fatigue, myalgias, arthralgias without arthritis, dysesthesia/paresthesia, and mood and memory disturbances after standard courses of antibiotic treatment for Lyme disease. This constellation of symptoms has been variously referred to as "chronic Lyme disease," "post-Lyme disease syndrome," and "post-treatment chronic Lyme disease." Persistent symptoms have been reported in patients who are seropositive for IgG antibodies against Borrelia burgdorferi as well as in patients who are seronegative. The cause or causes of persistent symptoms in these patients have not been clearly defined and are controversial. Because of the temporal association of these symptoms with infection with B. burgdorferi, some patients have been treated with prolonged courses of antibiotics. Case reports and uncontrolled trials have reported the efficacy of prolonged antibiotic therapy, often with relapse of the symptoms after discontinuation of therapy. To date, only one randomized, placebo-controlled, double-blind trial of antibiotic therapy for these patients has been published. An abstract of a second placebo-controlled trial of antibiotic therapy in a smaller cohort has also been presented. This paper will describe this patient population in detail and will review the clinical, microbiological, and selected biochemical and immunologic parameters and their responses to antibiotic treatment in the setting of a controlled trial.

What the main prognostic factors are in order to make this selection remains a matter of discussion. Introducing a 'holistic approach' for the first time in chronic myeloid leukemia, as practiced in other diseases, and looking at the patient in a complete picture, considering several variables, such as comorbidities, age, concomitant drugs, lifestyle and patient expectations, may be of help to understand, patient by patient, the best therapeutic strategy.

    Objective: To evaluate the onset of efficacy of TEV-48125, a monoclonal antibody against calcitonin gene-related peptide, recently shown to be effective for the preventive treatment of chronic migraine (CM) and high-frequency episodic migraine. Methods: A randomized placebo-controlled study tested once-monthly injections of TEV-48125 675/225 mg or 900 mg vs placebo. Headache information was captured daily using an electronic headache diary. The primary endpoint was change from baseline in the number of headache hours in month 3. Herein, we assess the efficacy of each dose at earlier time points. Results: The sample consisted of 261 patients. For headache hours, the 675/225-mg dose separated from placebo on day 7 and the 900-mg dose separated from placebo after 3 days of therapy (p = 0.048 and p = 0.033, respectively). For both the 675/225-mg and 900-mg doses, the improvement was sustained through the second (p = 0.004 and p < 0.001) and third (p = 0.025 and p < 0.001) weeks of therapy and throughout the study (month 3, p = 0.0386 and p = 0.0057). For change in weekly headache days of at least moderate intensity, both doses were superior to placebo at week 2 (p = 0.031 and p = 0.005). Conclusions: TEV-48125 demonstrated a significant improvement within 1 week of therapy initiation in patients with CM. Classification of evidence: This study provides Class II evidence that for patients with CM, TEV-48125 significantly decreases the number of headache hours within 3 to 7 days of injection.

    Aim: This study aims to explore the clinical, microbiological, and biochemical impact of azithromycin (AZM) buccal patch in chronic generalized patients as a monotherapy as well as an adjunct to nonsurgical therapy. Materials and Methods: A parallel design was used forty periodontitis patients were randomly allocated into five groups, namely Group 1 scaling root planing (SRP) alone, Group 2 (SRP + AZM patch group), Group 3 (SRP + AZM tablet group), Group 4 (AZM patch monotherapy), and Group 5 (AZM tablet as monotherapy). Plaque index, gingival bleeding index, modified gingival index, probing pocket depth (PPD), and clinical attachment level (CAL) were assessed at baseline and 21 and 90 days. Subgingival pooled plaque sample was collected to assess periodontopathogens like Porphyromonas gingivalis and Prevotella intermedia (Pi) by anaerobic culture method. Tumor necrosis factor alpha (TNF-α) was also evaluated at baseline and 21 days. Periodontal maintenance was performed in Group 1 until 90th day, and clinical parameter was assessed at the end of 90th day. Results: SRP + AZM tablets showed greater reduction in clinical parameters (P < 0.05) AZM as monotherapy did not offer clinical benefits over SRP. Baseline data were compared at the end, i.e., 90th day a significant reduction in plaque scores, gingival bleeding, and PPD was observed however no significant gain in the clinical attachment was observed. Conclusion: The monotherapy resulted in no improvement of periodontal parameters, microbial parameters, and TNF-α level. It is safe to use AZM + SRP as a mode of nonsurgical treatment in periodontitis patients. PMID:27127325

    2009-01-01

    Lateral ankle sprains are amongst the most common injuries incurred by athletes, with the high rate of reoccurrence after initial injury becoming of great concern. Chronic ankle instability (CAI) refers to the development of repetitive ankle sprains and persistent residual symptoms post-injury. Some of the initial symptoms that occur in acute sprains may persist for at least 6 months post-injury in the absence of recurrent sprains, despite the athlete having returned to full functional activity. CAI is generally thought to be caused by mechanical instability (MI) or functional instability (FI), or both. Although previously discussed as separate entities, recent research has demonstrated that deficits associated with both MI and FI may co-exist to result in CAI. For clinicians, the main deficits associated with CAI include deficits in proprioception, neuromuscular control, strength and postural control. Based on the literature reviewed, it does seem that subjects with CAI have a deficit in frontal plane ankle joint positional sense. Subjects with CAI do not appear to exhibit any increased latency in the peroneal muscles in response to an external perturbation. Preliminary data suggest that feed-forward neuromuscular control may be more important than feed-back neuromuscular control and interventions are now required to address deficits in feed-forward neuromuscular control. Balance training protocols have consistently been shown to improve postural stability in subjects with CAI. Subjects with CAI do not experience decreased peroneus longus strength, but instead may experience strength deficits in the ankle joint invertor muscles. These findings are of great clinical significance in terms of understanding the mechanisms and deficits associated with CAI. An appreciation of these is vital to allow clinicians to develop effective prevention and treatment programmes in relation to CAI.

    Background While chronic constipation (CC) clinical trials have focused primarily on bowel symptoms (symptoms directly related to bowel movements), abdominal symptoms are also prevalent among patients. The United States Food and Drug Administration’s (FDA’s) guidance on the use of patient-reported outcome measures to support product approvals or labeling claims recommends that endpoints be developed with direct patient input and include all symptoms important to patients. Aim To identify a comprehensive set of CC symptoms that are important to patients for measurement in clinical trials. Methods Following a targeted literature review to identify CC symptoms previously reported by patients, 28 patient interviews were conducted consistent with the FDA’s guidance on patient-reported outcomes. Subsequent to open-ended questions eliciting descriptions of all symptoms, rating and ranking methods were used to identify those of greatest importance to patients. Results All 67 studies reviewed included bowel symptoms; more than half also addressed at least one abdominal symptom. Interview participants reported 62 potentially distinct concepts: 12 bowel symptoms; 21 abdominal symptoms; and 29 additional symptoms/impacts. Patients’ descriptions revealed that many symptom terms were highly related and/or could be considered secondary to CC. The rating and ranking task results suggest that both bowel (for example, stool frequency and consistency) and abdominal symptoms (for example, bloating, abdominal pain) comprise patients’ most important symptoms. Further, improvements in both bowel and abdominal symptoms would constitute an improvement in patients’ CC overall. Conclusion Abdominal symptoms in CC patients are equal in relevance to bowel symptoms and should also be addressed in clinical trials to fully evaluate treatment benefit. PMID:24940076

    Obsessive compulsive symptoms are commonly reported in those with schizophrenia. Clozapine has previously been reported to induce, aggravate and alleviate these symptoms. It is unclear if these are similar to the symptoms experienced by those with obsessive compulsive disorder. This study describes the obsessive compulsive symptom profile of a population of patients with schizophrenia treated with clozapine (n = 62) and compares this with patients with Obsessive Compulsive Disorder (n = 35). All participants were attending an outpatient community mental health service. The Obsessive Compulsive Inventory (which measures the frequency and associated distress of a range of "behavioural" and "cognitive" symptoms), the Hospital Anxiety and Depression Scale and a demographic questionnaire were completed. In addition the schizophrenia group treated with clozapine completed the Brief Psychiatric Rating Scale. The OCD group reported significantly more symptoms for all OCI subscales compared to the clozapine group. Overall fourteen (22%) of the schizophrenia treated with clozapine group had clinically significant total OCI scores. Two (3%) had documented OCS pre clozapine. De novo OCS was reported in twelve (19%) cases. Nine (11%) had documented OC symptoms pre-clozapine while only two (3%) had symptoms after clozapine was initiated. In terms of OC symptom profile, the clozapine group scored highest on the Doubting scale, a cognitive symptom whereas the OCD group scored highest on Washing, a behavioural symptom. Both groups reported greater distress with cognitive rather than behavioural symptoms. Medication including clozapine dose was not correlated with symptom severity. Anxiety correlated highly with obsessive compulsive symptoms in the Clozapine group but not the OCD group. Within the Clozapine group, Obsessing correlated highly with Unusual Thought Content. Findings suggest that obsessive compulsive symptoms in the Clozapine group may reflect a subtype of 'schizo

    The present study was designed to evaluate the behavioral and neurochemical profiles of clozapine and risperidone in rats in a dose-dependent manner. Animals injected intraperitoneally (i.p.) with clozapine (2.5, 5.0 and 10.0 mg kg-1) or risperidone (1.0, 2.5 and 5.0 mg kg-1) were sacrificed 1 h later to collect brain samples. Hypolocomotive effects (home cage activity and catalepsy) were successively monitored in each animal after the drug or saline administration. Both drugs significantly (p < 0.01) decreased locomotor activity at high doses and in a dose-dependent manner. Maximum (100%) cataleptic potential was achieved at a high dose (5.0 mg kg-1) of risperidone. Neurochemical estimations were carried out by HPLC with electrochemical detection. Both drugs, at all doses, significantly (p < 0.01) increased the concentration of homovanillic acid (HVA), a metabolite of dopamine (DA), in the striatum. Dihydroxyphenylacetic acid (DOPAC) levels increased in the striatum and decreased in the rest of the brain, particularly in clozapine-injected rats. 5-Hydroxyindoleacetic acid (5-HIAA), the predominant metabolite of serotonin, significantly (p < 0.01) decreased in the striatum. 5-Hydroxytryptamine (5-HT) was significantly (p < 0.01) increased by risperidone and decreased by clozapine in the rest of the brain. Striatal tryptophan (TRP) was significantly (p < 0.01) decreased by risperidone and increased in the rest of the brain. The striatal HVA/DA ratio increased and the 5-HT turnover rate remained unchanged in the rest of the brain. Results suggest that the affinity of the two drugs towards D2/5-HT1A receptors interaction is involved in lower incidence of extrapyramidal side effects. Role of 5-HT1A receptors in the treatment of schizophrenia is discussed. PMID:21134850

    Uncomplicated chronic rhinosinusitis (CRS) is generally treated with medical therapy initially and surgery is contemplated only after medical therapy has failed. However, there is considerable variation in the medical treatment regimens used and studies defining their efficacy are few. The aim of this study was to determine the proportion of patients treated medically who responded sufficiently well so that surgery was not required. Subgroup analysis to identify clinical features that predicted a favorable response to medical therapy was also performed. Eighty patients referred to the Otorhinolaryngology Clinic at North Shore Hospital were treated with a standardized medical therapy protocol (oral prednisone for 3 weeks, oral antibiotics and ongoing saline lavage and intranasal budesonide spray). Symptom scores were collected before and after medical therapy. Clinical features such as presence of polyps, asthma, and aspirin hypersensitivity were recorded. Failure of medical therapy was defined as the persistence of significant CRS symptoms, and those patients who failed medical therapy were offered surgery. Follow-up data were available for 72 (90%) patients. Of this group, 52.5%, (95% CI, 42.7%, 62.2%) failed to respond adequately to medical therapy and were offered surgery. The remaining patients (37.5%) were successfully treated with medical therapy and did not require surgery at the time of follow-up. The premedical therapy symptom scores were significantly higher than the postmedical therapy symptom scores (p < 0.01). The symptom scores of those patients postmedical therapy who proceeded to have surgery were significantly higher than the group who responded well to maximum medical therapy (MMT) and did not require surgery (p < 0.0001). There were no significant differences in the proportion of patients with asthma, aspirin sensitivity, or polyps between the groups failing or not failing MMT. In approximately one-third of patients with CRS, medical therapy

    The purpose of this pilot study is to determine if an association exists between clozapine-associated weight gain and resting metabolic rate (RMR). In doing so, we used a "pretest-posttest" single group design in which we measured resting metabolic rate and total body weight prior to implementing clozapine therapy and then again approximately 1 month after initiating clozapine therapy. The results of three patients treated with clozapine revealed an inverse relationship between resting metabolic rate and total body weight. Resting metabolic rates were notably reduced by 10.3-16.0% whereas total body weights had increased between 2.9 and 9 kg. To our knowledge, this is the first documentation of an antipsychotic medication being associated with the reduction in resting metabolic rate. PMID:15061248

    As a keratinized material, nail recently has attracting researchers' attention in the pharmaceuticals analysis. There are comparatively limited studies concerning nail's xenobiotic determination and its mechanism. This article reported the development of a sensitive, specific and reproducible LC-MS/MS method, which could be as a foundation of other studies on drug determination in nail. It can also be regarded as the first report on organic drug in mainland China. Sixteen nail samples from volunteers, who were ingested clozapine for more than nine months, are confirmed positive after being analyzed by the method. It is found that contents of clozapine in the patients' nails are above the nanogram level. Besides, a comparative study of clozapine concentration in nails and hair was made, with a result that there exists a correlation between the two materials in terms of clozapine concentration.

    The objective was to investigate the effect of nitrous/oxygen in chronic pain. Seventy-seven chronic pain patients referred to dental treatment with conscious sedation with nitrous oxide/oxygen had their records included in this research. Data were collected regarding the location and intensity of pain by the visual analogue scale before and after the treatment. Statistical analysis was performed comparing pre- and post-treatment findings. It was observed a remarkable decrease in the prevalence of pain in this sample (only 18 patients still had chronic pain, p < 0.001) and in its intensity (p < 0.001). Patients that needed fewer sessions received higher proportions of nitrous oxide/oxygen. Nitrous oxide may be a tool to be used in the treatment of chronic pain, and future prospective studies are necessary to understand the underlying mechanisms and the effect of nitrous oxide/oxygen in patients according to the pain diagnosis and other characteristics.

    Pre-treatment HCV quasispecies complexity and diversity may predict response to interferon based anti-viral therapy. The objective of this study was to retrospectively (1) examine temporal changes in quasispecies prior to the start of therapy and (2) investigate extensively quasispecies evolution in a group of 10 chronically infected patients with genotype 3a, treated with pegylated α2a-Interferon and ribavirin. The degree of sequence heterogeneity within the hypervariable region 1 was assessed by analyzing 20–30 individual clones in serial serum samples. Genetic parameters, including amino acid Shannon entropy, Hamming distance and genetic distance were calculated for each sample. Treatment outcome was divided into (1) sustained virological responders (SVR) and (2) treatment failure (TF). Our results indicate, (1) quasispecies complexity and diversity are lower in the SVR group, (2) quasispecies vary temporally and (3) genetic heterogeneity at baseline can be use to predict treatment outcome. We discuss the results from the perspective of replicative homeostasis. PMID:18613968

  19. A cognitive deficit induced in rats by chronic intermittent cold stress is reversed by chronic antidepressant treatment

    2010-01-01

    We have previously reported that 14-days of chronic intermittent cold (CIC) stress induced a cognitive deficit in reversal learning on the rat attentional set-shifting test. This effect may be related to dysregulation of 5-HT function in orbitofrontal cortex, as a model of cognitive dysfunction in depression. To test the ability of chronic antidepressant drug treatment to reverse the cognitive deficit induced by CIC, it was first necessary to assess the temporal characteristics of the CIC-induced cognitive deficit. Thus, in the first study, we assessed the duration of the cognitive deficit following 2-weeks CIC stress. Replicating previous experiments, CIC induced a reversal learning deficit tested 3 days after the last cold exposure. However, cognitive performance of CIC-stressed rats was no different from unstressed controls when tested 7, 14 or 21 days after termination of the stress treatment. We next compared behavior 3 days after 2-weeks CIC to that seen 3 days after 5-weeks CIC, and found similar deficits in reversal learning. Thus, in the final study, antidepressant drug treatment was initiated after 2-weeks of CIC stress, and was maintained for 3 weeks, concurrent with the continuation of CIC stress. Both chronic and acute treatment with the selective serotonin reuptake inhibitor, citalopram, but not the norepinephrine reuptake blocker, desipramine, reversed the cognitive deficit induced by CIC stress. Thus, this stress-induced cognitive deficit may be a useful model for cognitive deficits related to prefrontal cortical hypoactivity in depression, and for investigating neurobiological mechanisms underlying the beneficial effects of chronic antidepressant drug treatment.

    The case of a 52 year old woman with chronic severe refractory thrombocytopenia is presented. Over a three year period, her platelet count was persistently less than 20 × 109/litre (normal range, 150–400). She required repeated hospital admission for management of bleeding and received multiple blood transfusions. She was given repeated courses of steroids, immunosuppression, immunoglobulin, and splenectomy, without success, in an attempt to stop the chronic blood loss. Eventually, she was found to be profoundly hypothyroid. On correction of her thyroid deficiency the platelet count returned to the normal range and all bleeding stopped. The platelet count remains in the normal range three years later. PMID:15333667

    Clozapine is the most effective antipsychotic to date, but its benefits are counterbalanced by the risk of severe hematological effects. In this study, we analyzed whether clozapine inhibits polymorphonuclear (PMN) leukocyte chemotaxis. We found that clozapine, within the therapeutic concentration range, potently and selectively inhibits PMN chemotaxis induced by interleukin 8 (IL-8), a chemokine inducing neutrophil migration. The effect was not due to its action at dopamine, serotonin and muscarinic receptors, or to a direct antagonism to IL-8 receptors. Furthermore, clozapine did not inhibit PMN chemotaxis by its presumed toxic mechanism. In fact, after an overnight incubation in cell culture, the drug did not increase the physiological PMN apoptosis. An interference of clozapine with the autocrine release of leukotriene B4 (LTB4), a secondary chemoattractant secreted by neutrophils in response to the primary chemoattractant IL-8, was hypothesized. In agreement with this hypothesis, clozapine attenuated the IL-8-induced release of LTB4 in PMNs. A series of experiments with an antagonist of the LTB4 receptor, U75302, and an inhibitor of LTB4 synthesis, zileuton, provided support to this conjecture. Intriguingly MK-571, an inhibitor of the multi-drug resistance protein MRP4, playing a pivotal role in effluxing LTB4, completely blocked PMN chemotaxis induced by IL-8, but gave conflicting results when tested for its ability to reduce LTB4 release, increasing LTB4 efflux by itself but reducing the release when in combination with IL-8. The reduction of PMN chemotaxis due to clozapine could predispose patients to infections. Whether this effect is a prelude to clozapine agranulocytosis requires further investigation.

    Clozapine can cause severe adverse effects yet it is associated with reduced mortality risk. We test the hypothesis this association is due to increased clinical monitoring and investigate risk of premature mortality from natural causes. We identified 14 754 individuals (879 deaths) with serious mental illness (SMI) including schizophrenia, schizoaffective and bipolar disorders aged ≥ 15 years in a large specialist mental healthcare case register linked to national mortality tracing. In this cohort study we modeled the effect of clozapine on mortality over a 5-year period (2007-2011) using Cox regression. Individuals prescribed clozapine had more severe psychopathology and poorer functional status. Many of the exposures associated with clozapine use were themselves risk factors for increased mortality. However, we identified a strong association between being prescribed clozapine and lower mortality which persisted after controlling for a broad range of potential confounders including clinical monitoring and markers of disease severity (adjusted hazard ratio 0.4; 95% CI 0.2-0.7; p = .001). This association remained after restricting the sample to those with a diagnosis of schizophrenia or those taking antipsychotics and after using propensity scores to reduce the impact of confounding by indication. Among individuals with SMI, those prescribed clozapine had a reduced risk of mortality due to both natural and unnatural causes. We found no evidence to indicate that lower mortality associated with clozapine in SMI was due to increased clinical monitoring or confounding factors. This is the first study to report an association between clozapine and reduced risk of mortality from natural causes. PMID:25154620

    Clozapine can cause severe adverse effects yet it is associated with reduced mortality risk. We test the hypothesis this association is due to increased clinical monitoring and investigate risk of premature mortality from natural causes. We identified 14 754 individuals (879 deaths) with serious mental illness (SMI) including schizophrenia, schizoaffective and bipolar disorders aged ≥ 15 years in a large specialist mental healthcare case register linked to national mortality tracing. In this cohort study we modeled the effect of clozapine on mortality over a 5-year period (2007–2011) using Cox regression. Individuals prescribed clozapine had more severe psychopathology and poorer functional status. Many of the exposures associated with clozapine use were themselves risk factors for increased mortality. However, we identified a strong association between being prescribed clozapine and lower mortality which persisted after controlling for a broad range of potential confounders including clinical monitoring and markers of disease severity (adjusted hazard ratio 0.4; 95% CI 0.2–0.7; p = .001).

    Background Epidemiological evidence has suggested a link between beta2-agonists and increases in asthma mortality. There has been much debate about possible causal links for this association, and whether regular (daily) long-acting beta2-agonists are safe. Objectives The aim of this review is to assess the risk of fatal and non-fatal serious adverse events in trials that randomised patients with chronic asthma to regular formoterol versus placebo or regular short-acting beta2-agonists. Search methods We identified trials using the Cochrane Airways Group Specialised Register of trials. We checked websites of clinical trial registers for unpublished trial data and Food and Drug Administration (FDA) submissions in relation to formoterol. The date of the most recent search was January 2012. Selection criteria We included controlled, parallel design clinical trials on patients of any age and severity of asthma if they randomised patients to treatment with regular formoterol and were of at least 12 weeks’ duration. Concomitant use of inhaled corticosteroids was allowed, as long as this was not part of the randomised treatment regimen. Data collection and analysis Two authors independently selected trials for inclusion in the review. One author extracted outcome data and the second author checked them. We sought unpublished data on mortality and serious adverse events. Main results The review includes 22 studies (8032 participants) comparing regular formoterol to placebo and salbutamol. Non-fatal serious adverse event data could be obtained for all participants from published studies comparing formoterol and placebo but only 80% of those comparing formoterol with salbutamol or terbutaline. Three deaths occurred on regular formoterol and none on placebo; this difference was not statistically significant. It was not possible to assess disease-specific mortality in view of the small number of deaths. Non-fatal serious adverse events were significantly increased when

    Bronchial asthma and chronic obstructive pulmonary disease (COPD), as chronic airway inflammatory diseases, seriously threaten the health of human beings. Chinese medicine has obvious advantages in prevention and treatment of them. "Preventive treatment theory" is a sort summarization of preventive medicine in Chinese medicine. The theory is not only reflected at the disease prevention levels, also embodied in the active treatment and the rehabilitation process. It was especially deep and colorfully embodied in the prevention and treatment of chronic airway inflammatory diseases such as asthma and COPD. In this paper,clarified were the prevention and treatment targets, ways of thinking and methods in different stages of asthma and COPD from various viewpoints including prevention before disease occurrence, treating disease at disease onset, preventing the aggravation once disease occurs, and consolidation after disease occurs. We hope to improve ways of thinking and prevention and treatment levels of bronchial asthma and COPD by Chinese medicine. PMID:24063226

    Effects of acute and chronic tianeptine treatments on ethanol withdrawal syndrome were investigated in rats. Ethanol (7.2% v/v) was given to adult male Wistar rats by a liquid diet for 30 days. Acute or chronic (twice daily) tianeptine (5, 10 and 20 mg/kg) and saline were administered to rats intraperitoneally. Acute and last chronic tianeptine injections and saline were done 30 min before ethanol withdrawal testing. After 2nd, 4th and 6th hours of ethanol withdrawal, rats were observed for 5 min, and withdrawal signs which included locomotor hyperactivity, agitation, tremor, wet dog shakes, stereotyped behavior and audiogenic seizures were recorded or rated. Locomotor activity in naive (no ethanol-dependent rats) was also tested after acute tianeptine treatments. Acute but not chronic tianeptine treatment attenuated locomotor hyperactivity and agitation in ethanol-dependent rats. Both acute and chronic tianeptine treatment produced some significant inhibitory effects on tremor, wet dog shakes, stereotyped behaviors and audiogenic seizures during the ethanol withdrawal. Our results suggest that acute or chronic tianeptine treatment attenuates ethanol withdrawal syndrome in ethanol-dependent rats and this drug may be useful for treatment of ethanol-type dependence.

    Objectives: The objective of this study was to evaluate the prevalence and severity of clozapine-induced hypersalivation, and assess the impact hypersalivation has on global functioning. Methods: Participants attending a dedicated clozapine clinic were invited to undertake a structured interview regarding their experiences of clozapine-induced hypersalivation. Two psychometric instruments to measure hypersalivation, the Nocturnal Hypersalivation Rating Scale and the Drooling Severity and Frequency Scale were used. Results: Clozapine-induced hypersalivation was experienced by 92% of participants, with nocturnal hypersalivation more prevalent compared to daytime hypersalivation (85% versus 48%). Daytime drooling was severe in 18% of cases and was present on a frequent or constant basis for 20% of individuals. Hypersalivation had at least a moderate impact on the quality of life of 15% of study participants. Conclusions: Clozapine-induced hypersalivation is the most prevalent adverse effect experienced by patients treated with clozapine and negatively impacts on quality of life, particularly if daytime drooling is present. The development of further strategies to ameliorate this adverse effect is required given the demonstrated lack of success to date in managing this condition. PMID:27354906

    2013-11-14

    Diabetes secondary to pancreatic diseases is commonly referred to as pancreatogenic diabetes or type 3c diabetes mellitus. It is a clinically relevant condition with a prevalence of 5%-10% among all diabetic subjects in Western populations. In nearly 80% of all type 3c diabetes mellitus cases, chronic pancreatitis seems to be the underlying disease. The prevalence and clinical importance of diabetes secondary to chronic pancreatitis has certainly been underestimated and underappreciated so far. In contrast to the management of type 1 or type 2 diabetes mellitus, the endocrinopathy in type 3c is very complex. The course of the disease is complicated by additional present comorbidities such as maldigestion and concomitant qualitative malnutrition. General awareness that patients with known and/or clinically overt chronic pancreatitis will develop type 3c diabetes mellitus (up to 90% of all cases) is rather good. However, in a patient first presenting with diabetes mellitus, chronic pancreatitis as a potential causative condition is seldom considered. Thus many patients are misdiagnosed. The failure to correctly diagnose type 3 diabetes mellitus leads to a failure to implement an appropriate medical therapy. In patients with type 3c diabetes mellitus treating exocrine pancreatic insufficiency, preventing or treating a lack of fat-soluble vitamins (especially vitamin D) and restoring impaired fat hydrolysis and incretin secretion are key-features of medical therapy.

    Chronic, low level treatment with a carbon monoxide releasing molecule (CO-RM), CORM-A1, has been shown to prevent the development of obesity in response to a high fat diet. The objective of this study was to test the hypothesis that chronic, low level treatment with this CO-RM can reverse established obesity via a mechanism independent of food intake. Dietary induced obese mice were treated with CORM-A1, the inactive compound iCORM-A1, or saline every 48 hours for 30 weeks while maintained on a high fat (60%) diet. Chronic treatment with CORM-A1 resulted in a 33% decrease from initial body weight over the 30 week treatment period while treatment with iCORM and saline were associated with 18 and 25% gain in initial body weight over the same time frame. Chronic treatment with CORM-A1 did not affect food intake or activity but resulted in a significant increase in metabolism. CORM-A1 treatment also resulted in lower fasting blood glucose, improvement in insulin sensitivity and decreased heptatic steatosis. Chronic treatment with CO releasing molecules can reverse dietary induced obesity and normalize insulin resistance independent of changes in food intake or activity. These findings are likely though a mechanism which increases metabolism. PMID:27144091

    NT69L is a neurotensin receptor agonist with antipsychotic-like activity. NT69L blocks apomorphine-induced climbing in rats with no effect on stereotypic behavior, attenuates d-amphetamine-induced hyperactivity, and blocks pharmacologically-induced disruption of prepulse inhibition (PPI) of the startle response. Repeated administration of NT69L results in tolerance to some, but not to all of its effects. Because schizophrenic patients require long term treatment, chronic (21-day) administration of NT69L was tested in PPI with comparisons to chronic haloperidol and clozapine treatment. Sprague-Dawley rats received acute or 21 daily, subcutaneous injections of NT69L (1.0 mg/kg). On days one and 21 the NT69L injection was followed 30 min later by treatment with either saline; the dopamine agonist, d-amphetamine (5.0 mg/kg); or the serotonin 5-HT2A psychotomimetic receptor agonist [1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane] DOI (0.5 mg/kg). Experiments were repeated with either haloperidol (1 mg/kg) or clozapine (20 mg/kg) in place of NT69L. Acute injection of NT69L significantly blocked d-amphetamine and DOI disruption of PPI. As with the acute injection, 21 daily administrations of NT69L also blocked d-amphetamine- and DOI-induced disruption of PPI. The data show that animals do not develop tolerance to the antipsychotic-like effects of NT69L when tested in the PPI of the startle response. The persistent efficacy of NT69L with chronic treatment provides further support for the therapeutic use of neurotensin agonists to treat schizophrenia and possibly other disorders that are characterized by PPI deficits. The modulatory role of NT69L on the dopaminergic and serotonergic neurotransmission systems both of which are implicated in the pathophysiology of schizophrenia is discussed. PMID:19800922

    Histamine H1 blockade is one of the more prominent actions of the multi-receptor acting antipsychotic clozapine. It is currently not known how much this H1 antagonism of clozapine contributes to the therapeutic or adverse side effects of clozapine. The current studies with Sprague-Dawley rats were conducted to determine the participation of histaminergic H1 receptor subtype in sensorimotor plasticity and memory function affected by clozapine using tests of prepulse inhibition (PPI) and radial-arm maze choice accuracy. The PPI impairment caused by the glutamate antagonist dizocilpine (MK-801) was significantly attenuated by clozapine. In the current project, we found that the selective H1 antagonist pyrilamine also reversed the dizocilpine-induced impairment in PPI of tactile startle with an auditory prepulse. In the radial-arm maze (RAM), pyrilamine, like clozapine, impaired working memory and caused a significant dose-related slowing of response. Pyrilamine, however, decreased the number of reference memory errors. We have previously shown that nicotine effectively attenuates the clozapine-induced working memory impairment, but in the current study, nicotine did not significantly alter the effects of pyrilamine on the RAM. In summary, the therapeutic effect of clozapine in reversing PPI impairment was mimicked by the H1 antagonist pyrilamine, while pyrilamine had a mixed effect on cognition. Pyrilamine impaired working memory but improved reference memory in rats. Thus, H1 antagonism seems to play a role in part of the beneficial actions of antipsychotics, such as clozapine.

    Chronic migraine, a subtype of migraine defined as ≥ 15 headache days per month for ≥ 3 months, in which ≥ 8 days per month meet criteria for migraine with or without aura or respond to migraine-specific treatment, is a disabling, underdiagnosed, and undertreated disorder associated with significant disability, poor health-related quality of life, and high economic burden. The keys to caring for chronic migraine patients include: (1) making a proper diagnosis; (2) identifying and eliminating exacerbating factors; (3) assessing for medication overuse (patients with chronic headache often overuse acute medications); and (4) continued management. Communication between patient and physician about treatment goals is important. The patient management guidelines presented in this article should help physicians improve treatment success and proactively address common comorbidities among their patients with chronic migraine.

    Stress is known to alter cognitive functions, such as memory, and it has been linked to the pathophysiology of mood and anxiety disorders. Chronic lithium treatment is used in some psychiatric disorders and has been suggested to act upon mechanisms which can enhance neuronal viability. The purpose of this work is to investigate a possible effect of lithium treatment in a chronic stress model. Adult male Wistar rats were divided in two groups, control and chronically stressed, treated either with normal chow or with chow containing LiCl for 40 days. Stress treatment was a chronic variable stress model, consisting of different stressors which were applied in a random fashion, once a day, every day. Memory was assessed by using the water maze task. The results demonstrated a marked decrease in reference memory in the water maze task in chronically stressed rats. This effect was attenuated by lithium treatment in all the parameters considered. No effect was observed in the working memory. These results indicate that lithium treatment may counteract some effects of chronic stress situations, particularly concerning spatial memory.

    Recent investigations of the cellular and molecular mechanisms of pain provide new hopes for more effective treatments for patients with chronic pain. At the molecular and genetic levels, new proteins and genes related to sensory sensation have been identified. However, many of these new discoveries have not resulted in better and more effective treatments for chronic pain. This disconnect between discovery and better treatment options is due, in part to the negative side effects associated with new treatment options, and also as a result of the ineffectiveness of these new drugs for inhibiting chronic pain. In this review, I will explore this disconnect between discovery and treatment, and propose that the failure of previous medicines can be due to their limited effects on injury-related plasticity, and question the common misperception of seeking compounds for high efficacy before understanding basic mechanisms of the target proteins in pain-related plasticity.

    Scedosporium apiospermum is a rare cause of fungal vertebral osteomyelitis that may result in chronic infection requiring multiple surgical interventions and long-term medical therapy. This case is the seventh one reported in the literature and is the first to include salvage surgery of a previous major spinal reconstruction. This report is also the first to describe the use of the new antifungal agent voriconazole. In treating this case of chronic vertebral osteomyelitis, several principles are emphasized from both the surgical and medical perspectives. From a surgical perspective, the use of salvage surgery, temporary avoidance of spinal instrumentation, and an appropriate choice of graft materials are emphasized. From a medical perspective, confirmation of the diagnosis, the need for long-term antifungal therapy, the need for long-term patient compliance, and the use of the new antifungal agent voriconazole are emphasized. Application of these principles has led to an adequate 2-year outcome.

    Over 240 million people worldwide are chronically infected with hepatitis B virus (HBV) and although a prophylactic vaccine and effective antiviral therapies are available, no cure exists. Curative regimens are urgently needed because up to one million deaths per year are caused by HBV-related liver cancer and end-stage liver disease. HBV is an hepatotropic virus which belongs to the Hepadnaviridae family and replicates its DNA genome via a reverse transcriptase mechanism. Effective therapies have been developed for chronic hepatitis B (CHB) infection in the last two decades. They rely on the use of interferon alpha and its pegylated formulation, and on nucleos(t)ide analogs that inhibit viral polymerase activity. Their results are discussed in this review as well as future perspectives. PMID:27318098

    Accurate evaluation of the degree of liver fibrosis in patients with chronic liver diseases (CLD) is crucial, as liver fibrosis is important in determining the prognosis of liver diseases. Currently, liver biopsy (LB) is considered the gold standard for staging liver fibrosis or cirrhosis. However, utilization of LB in clinical practice is often limited because of its invasive nature, sampling error and interobserver variability. Recently, transient elastography (TE) was introduced as a noninvasive, highly reproducible technique for assessing the degree of liver fibrosis. After extensive studies, TE is now regarded as a reliable surrogate marker for grading the severity of liver fibrosis in patients with CLD. In the past few years, the role of TE in monitoring liver stiffness and determining prognosis in patients with chronic hepatitis B (CHB) or chronic hepatitis C (CHC) who are undergoing antiviral treatment has been investigated. In patients with CHB, liver stiffness values decrease with antiviral treatment. TE can also be used to predict the incidence of liver-related events during antiviral treatment. In patients with CHC, TE can be used to monitor potential regression of liver fibrosis after antiviral treatment and may predict the treatment outcome of CHC. In addition, TE is an adjunct tool for distinguishing inactive hepatitis B virus carriers from patients with chronic active hepatitis. This review article discusses the important findings from recent studies focusing on the clinical application of TE in patients with chronic viral hepatitis who are undergoing antiviral treatments.

    Rheumatoid arthritis (RA) patients with chronic kidney failure are intolerant to most disease-modifying antirheumatic drugs (DMARDs) and NSAIDs due to their potential toxicities. Although the tumor necrosis factor (TNF) inhibitors have emerged as a highly effective treatment for RA, their safety and efficacy in RA patients with chronic kidney failure have not been well reported. We retrospectively evaluated the safety and efficacy of etanercept treatment in RA patients with chronic kidney failure. We describe three RA patients with chronic kidney failure who had been treated with DMARDs, steroids and NSAIDs, but were discontinued from these classical agents due to several side effects and nephrotoxicity. The patients were treated with 25 mg of etanercept once or twice a week. We evaluated disease activity and used decreasing renal function and increasing number of infections to monitor safety. All three patients improved after starting etanercept treatment and their steroid requirements were decreased. Linear relationships between Modification of Diet in Renal Disease study equation (MDRD) glomerular filtration rate (GFR) and time were observed. Thus, in all patients, the changes in GFR did not represent superimposed acute drug toxicity, but rather chronic progressive renal failure. These cases show that etanercept may be a safe and effective treatment option for RA patients with chronic kidney failure.

    The combination of prescription opioid dependence and chronic pain is increasingly prevalent and hazardous to public health. Variability in pain may explain poor prescription opioid addiction treatment outcomes in persons with chronic pain. This study examined pain trajectories and pain volatility in patients with chronic pain receiving treatment for prescription opioid addiction. We conducted secondary analyses of adults with chronic pain (n = 149) who received buprenorphine/naloxone (BUP/NLX) and counseling for 12 weeks in an outpatient, multisite clinical trial. Good treatment outcome was defined as urine-verified abstinence from opioids at treatment endpoint (Week 12) and during at least 2 of the previous 3 weeks. Pain severity significantly declined over time during treatment (b = -0.36, p < .001). Patients with greater pain volatility were less likely to have a good treatment outcome (odds ratio = 0.55, p < .05), controlling for baseline pain severity and rate of change in pain over time. A 1 standard deviation increase in pain volatility was associated with a 44% reduction in the probability of endpoint abstinence. The significant reduction in subjective pain during treatment provides observational support for the analgesic effects of BUP/NLX in patients with chronic pain and opioid dependence. Patients with greater volatility in subjective pain during treatment have increased risk of returning to opioid use by the conclusion of an intensive treatment with BUP/NLX and counseling. Future research should examine underlying mechanisms of pain volatility and identify related therapeutic targets to optimize interventions for prescription opioid addiction and co-occurring chronic pain.

    2005-01-01

    Since the introduction of behavioral medicine in the early 70s, cognitive-behavioral treatment interventions for chronic pain have expanded considerably. It is now well established that these interventions are effective in reducing the enormous suffering that patients with chronic pain have to bear. In addition, these interventions have potential economic benefits in that they appear to be cost-effective as well. Despite these achievements, there is still room for improvement. First, there is a substantial proportion of patients who do not appear to benefit from treatment interventions available. Second, although the effect sizes of most cognitive-behavioral treatments for chronic pain are comparable to those in psychopathology, they are quite modest. Third, there is little evidence for differential outcomes for different treatment methods. Fourth, there still is relatively little known about the specific biobehavioral mechanisms that lead to chronic pain and pain disability. One direction is to better match treatment programs to patients' characteristics. This can be done according to an "Aptitude X Treatment Interaction" framework, or from the perspective of the Moderator-Mediator distinction. In this introduction to the special series on what works for whom in cognitive-behavioral treatments for chronic pain, we review existing knowledge concerning both moderating and mediating variables in cognitive-behavioral treatments for chronic pain. We further argue in favor of theory-driven research as the only way to define specific a priori hypotheses about which patient-treatment interactions to expect. We also argue that replicated single-participant studies, with appropriate statistics, are likely to enhance new developments in this clinical research area.

Despite variance in origin or pathogenesis, these conditions are similarly characterized by chronic pain, poor physical function, mobility limitations, depression, anxiety, and sleep disturbance, and they are treated alone or in combination by pharmacologic and non-pharmacologic approaches, such as physical activity (aerobic conditioning, muscle strengthening, flexibility training, and movement therapies). Physical activity improves general health, disease risk, and progression of chronic illnesses such as cardiovascular disease, type 2 diabetes, and obesity. When applied to chronic pain conditions within appropriate parameters (frequency, duration, and intensity), physical activity significantly improves pain and related symptoms. For chronic pain, strict guidelines for physical activity are lacking, but frequent movement is preferable to sedentary behavior. This gives considerable freedom in prescribing physical activity treatments, which are most successful when tailored individually, progressed slowly, and account for physical limitations, psychosocial needs, and available resources.

    Tyrosine kinase inhibitors, now numbering 5 for the treatment of Philadelphia chromosome-positive leukemia, have proven ability to reduce clonal disease burden rapidly, dramatically, and durably, especially in chronic myeloid leukemia in the chronic phase. Deep molecular remissions are likely in most chronic phase patients and expectations on timing of response have been developed, validated as best as possible, and evolved over time. Increasing attention has been given to the initial decline of Bcr-Abl1 transcripts and the ultimate depth of molecular remission, overshadowing but not displacing the traditional role of cytogenetic response. This chapter reviews the evolution of response milestones for chronic phase chronic myeloid leukemia and tries to answer the question of how little disease is too much.

    Several tyrosine kinase inhibitors (TKIs) are now approved for the treatment of chronic myeloid leukemia in chronic phase. The efficacy of these drugs has been repeatedly demonstrated, as has their tolerability in most patients. However, late and chronic toxicities become an important issue for many patients facing long-term TKI exposure. For patients on long-term imatinib, gastrointestinal events, fluid retention, muscle cramps, fatigue, and hepatotoxicity are among the most common and most clinically relevant adverse events (AEs). A few of these have also emerged as important AEs with some of the newer TKIs. Distinct long-term toxicity concerns have emerged for dasatinib (pleural effusion, pulmonary hypertension, headache, and dyspnea) and nilotinib (rash, headache, myalgia, alopecia, and hyperglycemia), whereas due to the recent approval of bosutinib and ponatinib, their long-term toxicity profiles have not been fully characterized. Clinical experience with each of these drugs is accumulating, and ensuring proper adherence and monitoring for potential AEs is essential for effective treatment. PMID:27713843

    The treatment of patients with chronic wounds is becoming increasingly complex. It was therefore the aim of the members of the working group for wound healing (AGW) of the German Society of Dermatology (DDG) to report on the currently relevant aspects of non-interventional, topical wound treatment for daily practice. -Beside necessary procedures, such as wound cleansing and débridement, we describe commonly used wound dressings, their indications and practical use. Modern antiseptics, which are currently used in wound therapy, usually contain polyhexanide or octenidine. Physical methods, such as negative-pressure treatment, are also interesting options. It is always important to objectify and adequately treat pain symptoms which often affect these patients. Modern moist wound therapy may promote healing, reduce complications, and improve the quality of life in patients with chronic wounds. Together with the improvement of the underlying causes, modern wound therapy is an important aspect in the overall treatment regime for patients with chronic wounds.

    2-(14C)deoxyglucose autoradiography was used to determine local cerebral glucose utilization (lCGU) in rats following chronic cocaine treatment and subsequent abstinence. lCGU was examined in 43 discrete brain regions in animals which had received daily injections of cocaine for 14 days (10 mg/kg) followed by 3 days of saline or bromocriptine (10 mg/kg) treatment. Cocaine abstinence following chronic treatment significantly reduced lCGU in several regions including mesocorticolimbic structures such as ventral tegmental area, medial prefrontal cortex, and nucleus accumbens (NAc). Within the NAc, however, only the rostral pole showed significant reduction. In contrast, when bromocriptine treatment accompanied abstinence, lCGU was no longer reduced in mesocorticolimbic and most other regions, implying that metabolic recovery was enhanced by bromocriptine treatment during early abstinence following chronic cocaine treatment. These data suggest that cerebral metabolism is decreased during cocaine abstinence following chronic treatment in critical brain regions, and that this alteration can be prevented by treatment with direct-acting dopamine agonists such as bromocriptine.

    This case report evaluates virtual reality hypnosis (VRH) in treating chronic neuropathic pain in a patient with a 5-year history of failed treatments. The patient participated in a 6-month trial of VRH, and her pain ratings of intensity and unpleasantness dropped on average 36% and 33%, respectively, over the course of 33 sessions. In addition, she reported both no pain and a reduction of pain for an average of 3.86 and 12.21 hours, respectively, after treatment sessions throughout the course of the VRH treatment. These reductions and the duration of treatment effects following VRH treatment were superior to those following a trial of standard hypnosis (non-VR) treatment. However, the pain reductions with VRH did not persist over long periods of time. The findings support the potential of VRH treatment for helping individuals with refractory chronic pain conditions.

    2016-01-01

    Chronic Hepatitis C virus (HCV) infection carries a significant clinical burden in the United States, affecting more than 4.6 million Americans. Untreated chronic HCV infection can result in cirrhosis, portal hypertension, and hepatocellular carcinoma. Previous interferon based treatment carried low rates of success and significant adverse effects. The advent of new generation oral antiviral therapy has led to major improvements in efficacy and tolerability but has also resulted in an explosion of data with increased treatment choice complexity. Treatment guidelines are constantly evolving due to emerging regimens and real world treatment data. There also still remain subpopulations for whom current treatments are lacking or unclearly defined. Thus, the race for development of HCV treatment regimens still continues. This review of the current literature will discuss the current recommended treatment strategies and briefly overview next generation agents. PMID:27293521

    From 1990 to 2005 our department treated nine patients with chronic radial head dislocation by an ulnar osteotomy and indirect reduction by interosseous membrane. The patients varied in age from 2 years and 8 months to 10 years, and the time from the injury to operation ranged from 40 days to 3 years. The range of functional motion and carrying angle was restored in all nine patients, and no complications, such as recurrent dislocation, infection, or neurovascular injury were observed. This technique has proven to be a successful approach to treating such cases, with a low range of complications and good functional results. PMID:16741732

    In patients with chronic rhinitis, H1 receptor antagonists play an important role in relieving the symptoms of sneezing, itching, and rhinorrhea. New information about the pharmacokinetics and pharmacodynamics of first-generation H1 receptor antagonists such as chlorpheniramine has become available in the past few years. Comprehensive pharmacokinetic and pharmacodynamic studies of new relatively nonsedating H1 receptor antagonists such as terfenadine, astemizole, loratadine, and cetirizine are appearing. An understanding of the differences in pharmacokinetics and pharmacodynamics among H1 receptor antagonists is required for optimal use of these drugs.

    1990-07-01

    Opioid inhibition of phagocytosis in the protozoan ciliate Tetrahymena is antagonized by naloxone and this antagonism can be surmounted by increasing agonist concentration, which suggests a receptor-mediated mechanism. Desensitization of the opioid effect is time dependent in addition to concentration dependent. Chronic exposure to opioids results in the development of tolerance to the inhibitory effect of the agonists, and withdrawal of the latter results in a decrease in phagocytic capacity, which suggests that a state akin to dependence has been developed in these cells. Naloxone appears to behave as a partial agonist in tolerant cells, and there seems to exist cross-tolerance to mu and delta agonists.

  5. Fluvoxamine inhibition and carbamazepine induction of the metabolism of clozapine: evidence from a therapeutic drug monitoring service.

    1994-08-01

    Therapeutic drug monitoring data for clozapine were used to study interactions with other drugs. The distribution of the ratio concentration/dose (C/D) of clozapine was compared in four matched groups--patients simultaneously treated with benzodiazepines, patients on drugs that inhibit the cytochrome P450 enzyme CYP2D6, patients taking carbamazepine, and those not taking any of these drugs. No difference was seen among the monotherapy, CYP2D6, and benzodiazepine groups. Patients on carbamazepine had a mean 50% lower C/D than the monotherapy group (p < 0.001), indicating that carbamazepine is an inducer of the metabolism of clozapine. The C/D was inversely correlated to the daily dose of carbamazepine. Intraindividual comparisons in eight patients, with analyses both on and off carbamazepine, confirmed a substantial decrease of the clozapine concentration when carbamazepine was introduced. Four patients treated with clozapine were concomitantly given the antidepressant fluvoxamine. Three of them exhibited a much higher C/D ratio when on fluvoxamine compared with the monotherapy group. Two had their clozapine levels analyzed when on and off fluvoxamine. The dose-normalized clozapine concentration increased by a factor of 5-10 when fluvoxamine was added. We conclude that carbamazepine causes decreased clozapine plasma levels, while fluvoxamine increases the levels. The pathways are not known with certainty, but CYP1A2 may be of major importance for the metabolism of clozapine, since fluvoxamine is a potent inhibitor of this enzyme. A recent panel study suggests that determination of CYP1A2 activity with the caffeine test may be very useful for the dosing of clozapine. The induction of clozapine metabolism by carbamazepine might be partly mediated by CYP3A4.

  6. Environmental and behavioral controls of the expression of clozapine tolerance: Evidence from a novel across-model transfer paradigm

    Repeated administration of antipsychotic drugs induces a sensitization-like or tolerance-like effect in many behavioral tasks, including the conditioned avoidance response (CAR) and the phencyclidine (PCP)-induced hyperlocomotion, two rodent models with high predictive validity for antipsychotic activity. This study investigated the impacts of contextual and behavioral variables on the expression of clozapine tolerance using a recently validated across-model transfer paradigm (Zhang and Li, 2012). Male Sprague-Dawley rats were first repeatedly treated with clozapine (2.5–10.0 mg/kg, sc) in the CAR model or PCP (1.6 mg/kg, sc)-induced hyperlocomotion model for five consecutive days. They were then tested for the expression of clozapine tolerance in another model for another five days. Finally, all rats were switched back to the original model and tested again for the expression of clozapine tolerance. When tested in the PCP model, rats previously treated with clozapine in the CAR model did not show an immediate weaker inhibition of PCP-induced hyperlocomotion than those treated with clozapine for the first time, but showed a significantly weaker inhibition over time. In contrast, when tested in the CAR model, rats previously treated with clozapine in the PCP model showed an immediate weaker disruption of avoidance response than those treated with clozapine for the first time, but this weaker effect diminished over time. These results suggest that the expression of clozapine tolerance is strongly modulated by the test environment and/or selected behavioral response. Clozapine tolerance and its situational specificity may be related to the drug’s low extrapyramidal motor side effect, its superior therapeutic efficacy and/or emergence of clozapine withdrawal syndrome.

    2010-01-01

    Although chronic pancreatitis is a risk factor for pancreatic ductal adenocarcinoma (PDA), the relationship between chronic pancreatitis and PDA remains obscure. A critical obstacle to understanding the role of chronic pancreatitis is the lack of animal models. To develop one such model, mice were fed long-term with a choline deficient ethionine-supplemented (CDE) diet. Histological evaluation revealed that chronic pancreatitis, characterized by acinar atrophy, fibrosis and well-developed tubular complexes (TCs), was observed after 24 weeks of CDE diet treatment. Furthermore, expression of epidermal growth factor receptor (EGFR) and its ligands; serine protease inhibitor Kazal type 3 (Spink3) and transforming growth factor alpha (TGF alpha) and activation of K-Ras (GTP-Ras formation), which are frequently observed in human PDA, were indeed observed in parallel with TCs formation. Neoplastic lesions were not found after 54 weeks of treatment, suggesting that a continuation of CDE diet or another insult is required for the development of PDA.

    Dasatinib is one of the second-generation tyrosine kinase inhibitors used in imatinib resistance and/or intolerance, as well as in the frontline setting in patients with chronic myeloid leukemia-chronic phase, and also in patients with advanced disease. It is also utilized in Philadelphia chromosome-positive acute lymphocytic leukemia. While choosing the appropriate tyrosine kinase inhibitor (ie, dasatinib) for each individual patient, comorbidities and BCR-ABL1 kinase domain mutations should always be taken into consideration, among other things. This review mainly focuses on patient selection prior to dasatinib administration in the treatment of chronic myeloid leukemia. PMID:27784993

  12. Episodic and chronic migraine headache: breaking down barriers to optimal treatment and prevention.

    PubMed

    Lipton, Richard B; Silberstein, Stephen D

    2015-03-01

    Migraine is a common disabling primary headache disorder that affects an estimated 36 million Americans. Migraine headaches often occur over many years or over an individual's lifetime. By definition, episodic migraine is characterized by headaches that occur on fewer than 15 days per month. According to the recent International Classification of Headache Disorders (third revision) beta diagnostic criteria, chronic migraine is defined as "headaches on at least 15 days per month for at least 3 months, with the features of migraine on at least 8 days per month." However, diagnostic criteria distinguishing episodic from chronic migraine continue to evolve. Persons with episodic migraine can remit, not change, or progress to high-frequency episodic or chronic migraine over time. Chronic migraine is associated with a substantially greater personal and societal burden, more frequent comorbidities, and possibly with persistent and progressive brain abnormalities. Many patients are poorly responsive to, or noncompliant with, conventional preventive therapies. The primary goals of migraine treatment include relieving pain, restoring function, and reducing headache frequency; an additional goal may be preventing progression to chronic migraine. Although all migraineurs require abortive treatment, and all patients with chronic migraine require preventive treatment, there are no definitive guidelines delineating which persons with episodic migraine would benefit from preventive therapy. Five US Food and Drug Association strategies are approved for preventing episodic migraine, but only injections with onabotulinumtoxinA are approved for preventing chronic migraine. Identifying persons who require migraine prophylaxis and selecting and initiating the most appropriate treatment strategy may prevent progression from episodic to chronic migraine and alleviate the pain and suffering associated with frequent migraine.

    2014-08-01

    Loss of function in mitochondria, the key organelle responsible for cellular energy production, can result in the excess fatigue and other symptoms that are common complaints in almost every chronic disease. At the molecular level, a reduction in mitochondrial function occurs as a result of the following changes: (1) a loss of maintenance of the electrical and chemical transmembrane potential of the inner mitochondrial membrane, (2) alterations in the function of the electron transport chain, or (3) a reduction in the transport of critical metabolites into mitochondria. In turn, these changes result in a reduced efficiency of oxidative phosphorylation and a reduction in production of adenosine-5'-triphosphate (ATP). Several components of this system require routine replacement, and this need can be facilitated with natural supplements. Clinical trials have shown the utility of using oral replacement supplements, such as l-carnitine, alpha-lipoic acid (α-lipoic acid [1,2-dithiolane-3-pentanoic acid]), coenzyme Q10 (CoQ10 [ubiquinone]), reduced nicotinamide adenine dinucleotide (NADH), membrane phospholipids, and other supplements. Combinations of these supplements can reduce significantly the fatigue and other symptoms associated with chronic disease and can naturally restore mitochondrial function, even in long-term patients with intractable fatigue.

    Our aim is to present midterm results after endovascular repair of acute and chronic blunt aortic injury. Between December 1999 and December 2005, 13 patients were endovascularly treated for blunt aortic injury. Ten patients, 8 men and 2 women, mean age 38.7 years, were treated for acute traumatic injury in the isthmus region of thoracic aorta. Stent-graftings were performed between the fifth hour and the sixth day after injury. Three patients (all males; mean age, 66 years; range, 59-71 years) were treated due to the presence of symptoms of chronic posttraumatic pseudoaneurysm of the thoracic aorta (mean time after injury, 29.4 years, range, 28-32). Fifteen stent-grafts were implanted in 13 patients. In the group with acute aortic injury one patient died due to failure of endovascular technique. Lower leg paraparesis appeared in one patient; the other eight patients were regularly followed up (1-72 months; mean, 35.6 months), without complications. In the group with posttraumatic pseudoaneurysms all three patients are alive. One patient suffered postoperatively from upper arm claudication, which was treated by carotidosubclavian bypass. We conclude that the endoluminal technique can be used successfully in the acute repair of aortic trauma and its consequences. Midterm results are satisfactory, with a low incidence of neurologic complications.

    1991-09-01

    Quantitative autoradiographic procedures were used to examine the effects of chronic nicotine infusion on the number of central nervous system nicotinic cholinergic receptors. Female DBA mice were implanted with jugular cannulas and infused with saline or various doses of nicotine (0.25, 0.5, 1.0 or 2.0 mg/kg/hr) for 10 days. The animals were then sacrificed and the brains were removed and frozen in isopentane. Cryostat sections were collected and prepared for autoradiographic procedures as previously described. Nicotinic cholinergic receptors were labeled with L-(3H)nicotine or alpha-(125I)bungarotoxin; (3H)quinuclidinyl benzilate was used to measure muscarinic cholinergic receptor binding. Chronic nicotine infusion increased the number of sites labeled by (3H)nicotine in most brain areas. However, the extent of the increase in binding as well as the dose-response curves for the increase were widely different among brain regions. After the highest treatment dose, binding was increased in 67 of 86 regions measured. Septal and thalamic regions were most resistant to change. Nicotinic binding measured by alpha-(125I)bungarotoxin also increased after chronic treatment, but in a less robust fashion. At the highest treatment dose, only 26 of 80 regions were significantly changes. Muscarinic binding was not altered after chronic nicotine treatment. These data suggest that brain regions are not equivalent in the mechanisms that regulate alterations in nicotinic cholinergic receptor binding after chronic nicotine treatment.

    Successful treatment of many childhood diseases once considered terminal has resulted in the emergence of long-term effects of the disease or consequences of treatment that were previously unrecognized. Many of these long-term effects involve the central nervous system (CNS) and are developmental in the way that they emerge over time. Because we…

    Chronic kidney disease is a microvascular complication of diabetes mellitus (DM). Anemia is an important clinical manifestation to treat chronic kidney disease. Many subjects with poor socio-economic status having chronic kidney disease (CKD) and anaemia in a developing country can not afford the treatment with erythropoietin. This study has designed to see the efficacy of Nandrolone, a cheaper alternative; in comparison with recombinant human erythropoietin for management of anemia of pre-dialysis diabetic chronic kidney disease. Sixty adult diabetic patients with anaemia of chronic kidney disease on conservative treatment [Not on Hemodialysis (HD)] were enrolled. Patients were divided into two groups (Group 1 and Group 2) of 30 patients each. Group 1 patients received nandrolone deaconate 50 mg deep intramuscular and Group 2 recombinant human erythropoietin 100 IU per kilogram of body weight subcutaneously once weekly. Patients of both group received oral supplements in order to maintain body iron stores. All the relevant haematological and renal parameters were evaluated at the end of 3rd & 6th months. There was a statistically significant rise in haemoglobin concentration, packed cell volume, in both groups. The rise in haemoglobin concentration, in Group 2 was more marked followed by Group 1, at the end of 3rd, and 6th months. Nandrolone, though not equally effective, may be considered as a valid alternative therapy for the treatment of anemia of pre-dialysis diabetic chronic kidney disease to that of erythropoietin.

    The objective of the study was to investigate the effectiveness and efficacy of the randomized, parallel, and controlled trial of Traditional Chinese Medicine, general acteoside of Rehmanniae leaves, compared with piperazine ferulate in the treatment of primary chronic glomerulonephritis. Rehmanniae leaves and piperazine ferulate can reduce proteinuria and erythrocyturia effectively in the treatment of primary chronic glomerulonephritis. A total of 400 patients diagnosed with primary chronic glomerulonephritis were recruited from outpatient clinics and were randomly assigned to the treatment group (general acteoside of Rehmanniae leaves, two 200mg tablets, bid) or the control group (piperazine ferulate, four 50-mg tablets, bid ). The primary outcome was 24-h urinary protein. Secondary outcome measures included estimated glomerular filtration rate (eGFR), erythrocyturia, and electrolytes. After 8 weeks of treatment, the treatment group and the control group showed a mean reduction in 24-h proteinuria of 34.81% and 37.66%. The 95% CI of difference of the mean reduction in 24-h proteinuria between the two groups was [-11.50%, 5.80%]. No significant differences were found between the two groups in the erythrocyturia reduction. Neither group showed obvious changes between baseline and 8 weeks in eGFR or electrolytes. Adverse events occurred at a similarly low rate in the treatment group (1.5%) and control group (2.5%, P = 0.7238). Both general acteoside of Rehmanniae leaves and piperazine ferulate can reduce proteinuria and erythrocyturia effectively in the treatment of primary chronic glomerulonephritis.

    Treatment abandonment, the failure to complete therapy that is required for definitive disease control, frequently causes treatment failure for pediatric patients in low- and middle-income countries with chronic conditions, particularly cancer. Other forms of incomplete treatment affecting children in all settings, such as nonadherence and loss to follow-up, are often confused with treatment abandonment. Unclear definitions of incomplete treatment dramatically affect reported outcomes. To facilitate disease-specific and cross-sector analyses, we outline a practical approach to categorize forms of incomplete treatment, present distinct semantic categories with case examples and provide an algorithm that could be tailored to disease- and context-specific needs.

    Olanzapine and highly palatable diets can alter metabolism and brain function. We investigated the interaction of chronic treatment (4 months) with olanzapine and a cafeteria diet on metabolic parameters, memory tasks (spatial and aversive), the elevated plus maze and locomotor activity induced by d-amphetamine. Male Wistar rats were separated into the following groups: standard diet vehicle, standard diet and olanzapine, cafeteria diet vehicle and cafeteria diet and olanzapine. Olanzapine was administered in the drinking water (approximately 1.5 mg/kg/day), and after 3 days of treatment, the rats exhibited an expected anxiolytic effect and reduced amphetamine-induced hyperlocomotion. After 4 months of treatment, cafeteria diet vehicle and cafeteria diet olanzapine rats exhibited an increased body weight and heavier fat pads compared with the standard diet groups. Olanzapine increased only the epididymal and mesenteric fat pads. The cafeteria diet and olanzapine group showed greater glucose intolerance compared with all other groups. The cafeteria diet altered the effects of chronic olanzapine on the performance in the water maze and inhibitory avoidance tasks. Chronic olanzapine treatment failed to affect amphetamine-induced locomotion and to produce anxiolytic effects in the elevated plus maze task, regardless of the diet. Our results suggest that chronic olanzapine caused an increase in fat pads, which is putatively involved in the etiology of many metabolic diseases. Rats on the cafeteria diet were overweight and exhibited glucose intolerance. We did not observe these effects with olanzapine treatment with the standard diet. Moreover, the chronic treatment regimen caused tolerance to the antipsychotic and anxiolytic effects of olanzapine and seemed to potentiate some of the metabolic effects of the cafeteria diet. The cafeteria diet also modified the effects of chronic treatment with olanzapine on cognitive tasks, which may represent an undesirable effect of

    Recent articles have suggested that muscle biofeedback and transcendental meditation may be useful in treating chronic anxiety. To assess this, we conducted a controlled study comparing muscle biofeedback, transcendental mediation, and relaxation therapy. The study consisted of a six-week baseline period, six weeks of treatment, a six-week posttreatment observation period, and later follow-up. Thirty-one subjects completed the first part of the study and have been followed up for three to 18 months. Forty percent of the subjects had a clinically significant decrease in their anxiety. There were no differences between treatments with respect to treatment efficacy, onset of symptom amelioration, or maintenance of therapeutic gains. We found no evidence suggesting that the degree of muscle relaxation induced by any of the treatments is related to the therapeutic outcome. Relaxation therapies as a sole treatment appear to have a limited place in the treatment of chronic anxiety.

    A manifest clinical response has been achieved in 38 patients with chronic enteritis kept on apple diet in the form of apple powder produced from apple juice refuse. Carbohydrate loading with starch (polysaccharide), saccharose (disaccharide), glucose (monosaccharide), d-xylose made it clear that the apple powder improves hydrolysis and carbohydrate absorption: by 30%, 23%, 32% and 40% for starch, saccharose, glucose and d-xylose, respectively. Attenuation of the inflammation in the small intestine was also evident from the tendency to normalization of some fecal intestinal enzymes activity (entero-kinase, alkaline phosphatase). Changes in the systems PGE-cAMP and PGF-cGMP are suggested to play a role in the emergence of malabsorption syndrome, diarrhea, structural lesions in small intestinal mucosa.

    Heavy use of drugs impacts of the daily activities of individuals in these activities. Several groups of investigators have indeed documented changes in cognitive performance by individuals who have a long history of chronic drug use. In the case of marijuana, a wealth of information suggests that heavy long-term use of the drug may have neurobehavioral consequences in some individuals. In humans, heavy cocaine use is accompanied by neuropathological changes that might serve as substrates for cognitive dysfunctions. Similarly, methamphetamine users suffer from cognitive abnormalities that may be consequent to alterations in structures and functions. Here, we detail the evidence for these neuropsychological consequences. The review suggests that improving the care of our patients will necessarily depend on the better characterization of drug-induced cognitive phenotypes because they might inform the development of better pharmacological and behavioral interventions, with the goal of improving cognitive functions in these subsets of drug users.

The patients varied in age from 2 years and 8 months to 10 years, and the time from the injury to operation ranged from 40 days to 3 years. The range of functional motion and carrying angle was restored in all nine patients, and no complications, such as recurrent dislocation, infection, or neurovascular injury were observed. This technique has proven to be a successful approach to treating such cases, with a low range of complications and good functional results. PMID:16741732

    Seventy-four patients underwent operation for chronic pancreatitis during a 22 year period at UCLA Hospital. Follow-up data obtained for 60% of these patients an average of 3.2 years postoperation were analyzed by computer for statistically significant benefit between paired operation combinations and the variables of pain relief, stool habits, alcohol use, readmission for pancreatitis, and narcotic use. The combined group of total and cephalic pancreaticoduodenectomy proved more effective with respect to pain relief and readmission (p less than 0.05) than the group that had pseudocyst drainage. The comparison of groups that underwent resection or ductal drainage showed no statistical differences for the above variables. Regardless of type of operation, if the patient had evidence of pancreatic calcifications and had abstained from alcohol postoperatively, the likelihood of a return to normal activity was more favorable (p less than 0.05).

    Adenosine receptors have been the target of intense research with respect to potential use of selective ligands in a variety of therapeutic areas. Caffeine and theophylline are adenosine receptor antagonists, and over the past three decades a wide range of selective agonists and antagonists for adenosine receptor subtypes have been developed. A complication to the therapeutic use of adenosine receptor ligands is the observation that the effects of acute administration of a particular ligand can be diametrically opposite to the chronic effects of the same ligand. This ‘effect inversion’ is discussed here by Ken Jecobson and colleagues, and has been observed for effects on cognitive processes, seizures and ischaemic damage. PMID:8936347

    Chronic gastroparesis and CIP are debilitating disorders that are difficult to treat with currently available therapies. Failure of proper migration and differentiation of enteric neurons or ICC can result from specific genetic mutations and lead to phenotypes of CIP with or without concomitant gastroparesis. Intestinal dysfunction in diabetes may reflect a depletion of NO production (and perhaps other neurotransmitters or modulators), which is manifest as a syndrome of gastroparesis, diarrhea, or constipation in individual patients. As the key molecular changes underlying these disorders are defined, clinicians will begin to understand their precise etiology and rational medical therapy may become possible. In the future, testable hypotheses regarding the etiology of other functional bowel disorders (e.g., functional dyspepsia, irritable bowel syndrome, and so forth) may be developed.

    Chronic pain is a common reason for medical visits, but prevalence estimates vary between studies and have rarely included drug treatment data. This study aimed to examine characteristics of chronic pain and its relation to demographic and health factors, and factors associated with treatment of pain with opioid analgesics. A chronic pain module was added to the 2007 Kansas Behavioral Risk Factor Surveillance System (response rate = 61%). Data on prevalence, duration, frequency, and severity of chronic pain, demographics, and health were collected from a representative sample of 4090 adults 18 years and older by telephone. Logistic regression was used to examine the association of both chronic pain and opioid use with demographic and health factors. Chronic pain was reported by 26.0% of the participants and was associated with activity limitations (adjusted odds ratio [AOR] = 3.6, 95% confidence interval [95% CI] 2.8-4.5), arthritis (AOR = 3.3, 95% CI 2.6-4.0), poor mental health (AOR = 2.0, 95% CI 1.4-2.8), poor overall health (AOR = 1.9; 95% CI 1.5-2.5), and obesity (AOR = 1.6; 95% CI 1.2-2.0). Of the 33.4% of people with pain who use prescription pain medication, 45.7% took opioids, including 36.7% of those with mild pain. Chronic pain affects a quarter of adults in Kansas and is associated with poor health. Opioid analgesics are the mainstay of prescribed pharmacotherapy in this group, even among those reporting mild pain. Chronic pain affects 26.0% of adults in the state of Kansas, U.S.A. Overall, 45.7% of people who take prescription drugs for chronic pain reported taking opioid analgesics.

    The purpose of this article is to review the topic of interictal psychiatric comorbidity among adult patients with chronic epilepsy, focusing specifically on those studies that have used contemporary psychiatric nosology. Five specific issues are addressed: (a) the risk and predominant type(s) of psychiatric comorbidity in chronic epilepsy, (b) adequacy of recognition and treatment of psychiatric comorbidity, (c) the additional burdens that comorbid psychiatric disorders impose upon patients with chronic epilepsy, (d) the etiology of these disorders, and (e) strategies for treatment. Current appreciation for these issues in epilepsy is contrasted to related fields (e.g., primary care, psychiatry, and epidemiology), where considerable attention has been devoted to the identification, consequences, and treatment of psychiatric comorbidity. The issue of psychiatric comorbidity in epilepsy is reviewed with the aim of identifying a clinical and research agenda that will advance understanding of at least one important psychiatric condition associated with epilepsy-namely, major depression.

    Chronic pelvic pain has rarely been discussed in the pain management literature, although it is extremely common in general gynecological practice and often refractory to traditional medical and surgical therapy. A chronic pelvic pain program was developed to offer an alternative treatment approach for women for whom standard gynecological procedures were inappropriate or unsuccessful. Sixteen subjects completed the full 6-8 week interdisciplinary program, which included both somatic and behavioral therapies. Compared to a waiting list control the results showed a dramatic decrease in reported levels of pain following treatment. Anxiety and depression also decreased and psychosocial functioning improved, including return to work, increased social activities, and improved sexual activity. The outcome suggests that the interdisciplinary pain management approach is effective for the treatment of chronic pelvic pain. PMID:2352765

It is established, that the use of cycloferon liniment in the combined therapy decreases the infection load in periodontal recess and manifestation of local inflammation, normalizes the immunity indices, and reduces the level of endogenous intoxication. All these factors provide acceleration of the recuperation processes and decrease the frequency of recidivating.

    Chronic stressors and inflammatory immune activation may contribute to pathophysiological alterations associated with both major depression and cardiovascular disease. The present study, conducted in mice, assessed whether a chronic stressor of moderate severity that induced an anhedonic effect, when coupled with a bacterial endotoxin, lipopolysaccharide (LPS), additively or interactively provoked circulating and heart atrial natriuretic peptide (ANP), a potentially useful diagnostic and prognostic tool in cardiac diseases. As well, given the potential role of inflammatory processes in both depression and cardiovascular disease, we assessed pro-inflammatory mRNA expression in heart in response to the stressor and the LPS treatments. Male CD-1 mice that had been exposed to a chronic, variable stressor over 4 weeks displayed reduced sucrose consumption, possibly reflecting the anhedonic effects of the stressor. Treatment with LPS (10mug) provoked increased circulating corticosterone levels in both chronically stressed and non-stressed mice. Moreover, ANP concentrations in plasma and in the left ventricle were increased by both the stressor and the LPS treatments, as were left atrial and ventricular cytokine (interleukin-1beta; tumor necrosis factor-alpha) mRNA expression. Further, these treatments synergistically influenced the rise of plasma ANP. A link may exist between stressor-provoked depressive features (anhedonia) and immune activation, with elevated levels of ANP, a potential marker of cardiovascular disturbance. These findings are consistent with the view that chronic stressors and inflammatory immune activation may represent a common denominator subserving the frequent comorbidity between these illnesses.

  19. A neural model for chronic pain and pain relief by extracorporeal shock wave treatment.

    PubMed

    Wess, Othmar J

    2008-12-01

    The paper develops a new theory of chronic pain and pain relief by extracorporeal shock wave treatment. Chronic pain without underlying anatomical disorder is looked at as a pathological control function of memory. Conditioned reflexes are considered to be engraved memory traces linking sensory input of afferent signals with motor response of efferent signals. This feature can be described by associative memory functions of the nervous system. Some conditioned reflexes may cause inappropriate or pathological reactions. Consequently, a circulus vitiosus of pain sensation and muscle and/or vessel contraction is generated when pain becomes chronic (pain spiral). The key feature is a dedicated engram responsible for a pathological (painful) reaction. The pain memory may be explained by the concept of a holographic memory model published by several authors. According to this model it is shown how nervous systems may generate and recall memory contents. The paper shows how extracorporeal shock wave treatment may reorganize pathologic memory traces, thus giving cause to real and permanent pain relief. In a generalized manner, the idea of associative memory functions may help in the understanding of conditioning as a learning process and explain extracorporeal shock wave application as an efficient treatment concept for chronic pain. This concept may open the door for new treatment approaches to chronic pain and several other disorders of the nervous system.

    Antidepressants are often applied in the treatment of chronic pain. Analgesic action of tricyclic antidepressants (TCAs) has been extensively studied and proven. TCAs are associated with a number of adverse effects which are inconvenient for patients. The newer antidepressants have fewer side effects and equivalent efficacy on mood disorders. This article reviews the available publications (mainly placebo-controlled trials) concerning the efficacy of these medications in the treatment of chronic pain. The data regarding selective serotonin reuptake inhibitors (SSRI) are conflicting. Trazodone (a serotonin-reuptake inhibitor as well as a postsynaptic serotonin receptor antagonist) does not appear to be effective for the treatment of chronic pain. No placebo-controlled studies are available for noradrenergic and specific serotoninergic antidepressant (NaSSA)--mirtazapine and noradrenaline reuptake inhibitor (NaRI)--reboxetine. Bupropion, a noradrenaline and dopamine-reuptake inhibitor appears to be effective in the treatment of neuropathic pain. Venlafaxine--selective serotonin and noradrenergic reuptake inhibitors (SNRI) was shown to be effective in the treatment of different kinds of pain. Duloxetine (SNRI) is effective in relieving both the emotional and painful physical symptoms of depression. Additional randomized, controlled trials are necessary to fully evaluate the role of new antidepressants in the treatment of chronic pain. PMID:15771151

Three of the patients had suffered from poliomyelitis. All complained of increasing dyspnoea on exertion, ultimately interfering with almost every activity of daily life; three patients had severe acute respiratory failure necessitating urgent admission to the Respiratory Care Unit. Right heart failure was present in two. Two patients required mechanical treatment via an endotracheal tube. All the patients were discharged home with a cuirass respirator. Standard type shells were used initially with low efficiency due to the poor fit of the cuirass shell to the deformed thoracic cage. Tailor-made shells were constructed from polyester reinforced with glass fibre, modelled on plaster casts of the thoracic cage. Subjectively the patients improved greatly and were able to resume and increase many activities. One patient committed suicide for reasons unconnected with treatment but the other three patients have been doing well from the time the cuirass respirator treatment was started, respectively, 3, 6, and 10 years ago. This treatment seems particularly effective in younger patients with severe paralytic scoliosis and cardiorespiratory failure, although the possibility of using it in older patients suffering from scoliosis of other aetiology should certainly be explored.

    Efficacy of antidepressants fluvoxamine, amitriptyline and transcranial electrostimulation of the brain in the treatment of chronic daily headache has been studied. Amitriptyline had the highest effect in dosage 50 mg daily but was not well tolerated by patients that resulted in that only 50% of them finished the study. Fluvoxamine had high efficacy and good tolerability in the treatment of chronic daily headache and medication overuse headache. Small dosages of amitriptyline and fluvoxamine potentiated the analgesic effect of transcranial electrostimulation of the brain. The combination of antidepressants with transcranial electrostimulation of the brain alleviated the negative effect of the withdrawal of overused analgesics and may be recommended for out-patient use.

    Between 1972 and 1985, 107 patients with chronic Idiopathic Thrombocytopenic Purpura underwent splenectomy. Platelet life span and sites of sequestration were studied with labelled platelets and external scanning. Medical treatment was always of scarce and transient effectiveness and had considerable side effects. Splenectomy had minimal complications and mortality and caused no hazard of overwhelming sepsis in adults. The results of splenectomy were very satisfying, especially when platelet sequestration was mainly splenic (remission in about 90% of patients). Surgical treatment is at present the most effective in patients with chronic ITP.

    Targeted therapy has modernized the treatment of both chronic and acute lymphoblastic leukemia. The introduction of monoclonal antibodies and combinational drugs has increased the survival rate of patients. Preclinical studies with various agents have resulted in positive outputs with Phase III trial drugs and monoclonal antibodies entering clinical trials. Most of the monoclonal antibodies target the CD20 and CD22 receptors. This has led to the approval of a few of these drugs by the US Food and Drug Administration. This review focuses on the drugs under preclinical and clinical study in the ongoing efforts for treatment of acute and chronic lymphoblastic leukemia. PMID:27382259

    2014-06-01

    Sofosbuvir is a nucleotide analogue selective inhibitor of the RNA-directed RNA polymerase (NS5B) enzyme of the hepatitis C virus (HCV) genome. It has shown potent antiviral activity across all HCV genotypes and in a variety of patient populations, including treatment-naive patients; treatment-experienced patients who had failed previous standard therapy; patients with decompensated liver disease, including cirrhosis; and HIV co-infected patients. It is administered as a single, once-daily 400-mg tablet, has no food restrictions, has low potential for drug interactions, and requires no dose adjustment in mild to moderate kidney or liver impairment. When sofosbuvir is combined with pegylated interferon and/or ribavirin, its clinical and laboratory safety profile is similar to that which is expected from pegylated interferon or ribavirin alone. Rates of treatment discontinuation and dose reduction with sofosbuvir-containing regimens were lower than those commonly observed with pegylated interferon and ribavirin.

    Ten patients presenting with anovulatory syndrome (AS, 4 patients), inadequate luteal phase (ILP, 3 patients) and short luteal phase (SLP, 3 patients) were treated with epimestrol for 29 cycles in total. The initial treatment was always 10 mg/day for 10 days followed by a modification of the daily dose and/or length of treatment needed. Ovulation was induced in all 4 AS patients with an adequate luteal phase (ALP) in 3 of them. In all other patients (with ILP and SLP) an ALP was induced; 2 of them became pregnant. No side-effects were reported.

    Objective To understand the experiences and expectations of nurses in the treatment of women with chronic venous ulcers. Method Phenomenological research was based on Alfred Schütz, whose statements were obtained in January, 2012, through semi-structured interviews with seven nurses. Results The nurse reveals the difficulties presented by the woman in performing self-care, the perceived limitations in the treatment anchored in motivation, and the values and beliefs of women. It showed professional frustration because venous leg ulcer recurrence, lack of inputs, interdisciplinary work and training of nursing staff. There was an expected adherence to the treatment of women, and it emphasized the need for ongoing care, supported self-care and standard practices in treatment. Conclusion That treatment of chronic venous leg ulcers constitutes a challenge that requires collective investment, involving women, professionals, managers and health institutions. PMID:25517835

    2014-01-01

    The modern treatment era in chronic thromboembolic disease has seen significant advances in both surgical and medical treatment. One such treatment, the pulmonary endarterectomy (where established chronic organized thrombus is removed), has dramatically affected morbidity and mortality. These advances have outstripped basic research into the causes and pathophysiology of disease, which remain largely poorly understood. In this review, we will set out to explain some of the historical reasons for this, including the difficulties inherent in human studies and the lack of good animal models. We will review some of the recent advances in pathophysiology from registries and translational research, and we will summarize the treatment options, with some discussion of very recently published work, including medical and surgical treatments, both traditional and more experimental work in non-invasive techniques.

    Summary Background Ponatinib has shown efficacy in patients with refractory chronic myeloid leukaemia (CML) and in those with CML with a Thr315Ile mutation. We aimed to investigate the activity and safety of ponatinib as first-line treatment for patients with chronic-phase CML. Methods We did a single-arm, phase 2 trial at MD Anderson Cancer Center in Houston, TX, USA. Between May 3, 2012, and Sept 24, 2013, we enrolled patients with early (<6 months) chronic-phase CML and treated them with oral ponatinib once a day. Patients enrolled before July 25, 2013, were given a starting dose of 45 mg per day; we lowered this due to tolerability issues and patients enrolled after this date were given a starting dose of 30 mg per day. After a warning by the US Food and Drug Administration (FDA) in Oct 6, 2013, for vascular complications with ponatinib, we started all patients on aspirin 81 mg daily and reduced the dose of ponatinib to 30 mg or 15 mg per day for all patients. The primary endpoint was the proportion of patients who achieved complete cytogenetic response by 6 months in the per-protocol population. This trial is registered with ClinicalTrials.gov, number NCT01570868. Findings We enrolled 51 patients. Median follow-up was 20.9 months (IQR 14.9–25.2). 43 patients were started on 45 mg ponatinib every day; eight patients were started on 30 mg per day. 43 (94%) of 46 evaluable patients achieved complete cytogenetic response at 6 months. Most frequent toxicities included skin-related effects (n=35; 69%) and elevated lipase (n=32; 63%). Cardiovascular events (mainly hypertension) occurred in 25 (49%) patients. Grade 3–4 myelosuppression occurred in 15 (29%) patients. Five (10%) patients developed cerebrovascular or vaso-occlusive disease. 43 (85%) patients needed treatment interruptions at some time and 45 (88%) needed dose reductions. The study was terminated June 18, 2014, at the recommendation of the FDA due to concern about the increased risk of thromboembolism

    Chronic migraine is a common and debilitating headache syndrome. Botulinum neurotoxin, a potent toxin produced by the anaerobic bacterium clostridium botulinum, used largely for treatment of disorders associated with increased muscle tone and hyperhidrosis, is used for patients suffering from chronic migraine. In this study, a group of patients suffering from chronic migraine with medication overuse was treated with onabotulinum toxin A (Botox) to verify its efficacy for chronic migraine. The results confirmed the efficacy of onabotulinum toxin A (Botox) when used at the dosage of 155 UI according to the PREEMPT protocol. Although these results are preliminary, they led to intense efforts to evaluate the analgesic properties of onabotulinum toxin A (Botox) and to assess its use in clinical practice, in particular in migraine field.

    2014-01-01

    Chronic hepatitis B (CHB) virus infection is a global public health problem, affecting more than 400 million people worldwide. The clinical spectrum is wide, ranging from a subclinical inactive carrier state, to progressive chronic hepatitis, cirrhosis, decompensation, and hepatocellular carcinoma. However, complications of hepatitis B virus (HBV)-related chronic liver disease may be reduced by viral suppression. Current international guidelines recommend first-line treatment of CHB infection with pegylated interferon, entecavir, or tenofovir, but the optimal treatment for an individual patient is controversial. The indications for treatment are contentious, and increasing evidence suggests that HBV genotyping, as well as serial on-treatment measurements of hepatitis B surface antigen and HBV DNA kinetics should be used to predict antiviral treatment response. The likelihood of achieving a sustained virological response is also increased by extending treatment duration, and using combination therapy. Hence the paradigm for treatment of CHB is constantly evolving. This article summarizes the different indications for treatment, and systematically reviews the evidence for the efficacy of various antiviral agents. It further discusses the shortcomings of current guidelines, use of rescue therapy in drug-resistant strains of HBV, and highlights the promising clinical trials for emerging therapies in the pipeline. This concise overview presents an updated practical approach to guide the clinical management of CHB. PMID:24876747

    2013-10-01

    Treatment of CLL patients with conventional cytotoxic agents is often combined with significant toxicity that prevents broad application especially in elderly patients. In addition, relapse frequently occurs after application of conventional chemotherapy in CLL. Recently several new chemo-free treatment options have been introduced within clinical trials. Among them are monoclonal antibodies, most of them targeting the CD20 molecule: besides the licensed drugs rituximab and ofatumumab obinutuzumab, although in combination with chemotherapy, has recently shown high clinical efficacy in front-line treatment of elderly patients with CLL. Lenalidomide as monotherapy has demonstrated clinical efficacy in patients with relapsed disease and first data within clinical trials have been generated in the front-line setting. A promising class of novel agents has been designed to block aberrant signaling from the B-cell receptor. Ibrutinib acts by inhibiting the Bruton's tyrosine kinase (BTK) while idelalisib represents a first-in-class specific inhibitor of the phosphoinositol-3 kinase (PI3K) delta isoform. Another class of drugs with potential impact for chemo-free treatment strategies in CLL are the BH3-mimetic inhibitors of the Bcl-2 family of pro-survival proteins. Other interesting candidate drugs that are currently explored for CLL patients include small modular immunopharmaceutical (SMIP) proteins (e. g. TRU-016), CDK inhibitors (e. g. dinaciclib), HDAC inhibitors and others. Given all these novel agents and targets, chemo-free or at least chemo-reduced concepts may become reality in the near future for our patients suffering from CLL.

    Objective Given the critical role of behavior in preventing and treating chronic diseases, it is important to accelerate the development of behavioral treatments that can improve chronic disease prevention and outcomes. Findings from basic behavioral and social science research hold great promise for addressing behaviorally-based clinical health problems, yet there is currently no established pathway for translating fundamental behavioral science discoveries into health-related treatments ready for Phase III efficacy testing. This article provides a systematic framework for guiding efforts to translate basic behavioral science findings into behavioral treatments for preventing and treating chronic illness. Methods The ORBIT model for behavioral treatment development is described as involving a flexible and progressive process, pre-specified clinically significant milestones for forward movement, and return to earlier stages for refinement and optimization. Results This article presents the background and rationale for the ORBIT model, a summary of key questions for each phase, a selection of study designs and methodologies well-suited to answering these questions, and pre-specified milestones for forward or backward movement across phases. Conclusions The ORBIT model provides a progressive, clinically-relevant approach to increasing the number of evidence-based behavioral treatments available to prevent and treat chronic diseases.

    Objective This study explored the self-management strategies and treatment burden experienced by low income US primary care patients with chronic kidney disease. Methods Semi-structured interviews were conducted with 34 patients from two primary care practices on Buffalo’s East Side, a low-income community. Qualitative analysis was undertaken using an inductive thematic content analysis approach. We applied Normalization Process Theory (NPT) to the concept of treatment burden to interpret and categorize our findings. Results The sample was predominantly African-American (79%) and female (59%). Most patients (79%) had a diagnosis of Stage 3 CKD. Four major themes were identified corresponding to NPT and treatment burden: (1) Coherence – making sense of CKD; (2) Cognitive participation – enlisting support and organizing personal resources; (3) Collective action – self-management work; and (4) Reflexive monitoring – further refining chronic illness self-care in the context of CKD. For each component we identified barriers hindering patients’ ability to accomplish the necessary tasks. Conclusions Our findings highlight the substantial treatment burden faced by inner-city primary care patients self-managing CKD in combination with other chronic illnesses. Health care providers’ awareness of treatment burden can inform the development of person-centered care plans that can help patients to better manage their chronic illnesses. PMID:25416418

    Background. Transferrin is a negative acute phase protein, which decreases during inflammation and infection. The aim of the present investigation was to evaluate changes in the transferrin serum levels subsequent to non-surgical treatment of chronic periodontal disease. Methods. Twenty patients with chronic periodontitis and 20 systemically healthy subjects without periodontal disease, who had referred to Tabriz Faculty of Dentistry, were selected. Transferrin serum levels and clinical periodontal parameters (pocket depth, clinical attachment level, gingival index, bleeding index and plaque index) were measured at baseline and 3 months after non-surgical periodontal treatment. Data were analyzed with descriptive statistical methods (means ± standard deviations). Independent samples t-test was used to compare transferrin serum levels and clinical variables between the test and control groups. Paired samples t-test was used in the test group for comparisons before and after treatment. Statistical significance was set at P < 0.05. Results. The mean transferrin serum level in patients with chronic periodontitis (213.1 ± 9.2 mg/dL) was significantly less than that in periodontally healthy subjects (307.8 ± 11.7 mg/dL). Three months after periodontal treatment, the transferrin serum level increased significantly (298.3 ± 7.6 mg/dL) and approached the levels in periodontally healthy subjects (P < 0.05). Conclusion. The decrease and increase in transferrin serum levels with periodontal disease and periodontal treatment, respectively, indicated an inverse relationship between transferrin serum levels and chronic periodontitis.

  18. Chronic Antidepressant Treatment in Normal Mice Induces Anxiety and Impairs Stress-coping Ability

    Antidepressants are clinically used for patients with major depression. Antidepressant treatments in certain groups of patients are effective for relieving depression as well as anxiety disorder. However, it is not clearly known whether the use of current antidepressants in healthy persons is beneficial for upcoming depression- and anxiety-inducing life events. To address this question, normal mice were intraperitoneally administered with imipramine or fluoxetine for more than 2 weeks, and behaviors related to anxiety and depression were evaluated. Mice treated with imipramine or fluoxetine for more than 14 days exhibited significantly decreased immobility time in the forced swim test and tail suspension test, but these mice exhibited enhanced anxiety in several behavioral tests. Furthermore, chronic antidepressant treatments followed by sub-threshold level of stress in normal mice profoundly aggravated antidepressant-induced anxiety-like behaviors without further affecting depression-related behaviors. Chronic antidepressant treatments followed by sub-threshold level of stress produced swollen vesicles and ulcerations on the lips as well as a watery and inflammatory nose. Mice given chronic antidepressant treatments displayed intestinal abnormalities evidenced by a highly enlarged and inflamed small intestine full of defecation materials. These results suggest that chronic antidepressant treatment in normal mice provokes anxiety-like behaviors and impairs their stress-coping ability. PMID:26113795

    In gain-of-function STAT1 mutations, chronic mucocutaneous candidiasis disease (CMCD) represents the phenotypic manifestation of a complex immunodeficiency characterized by clinical and immunological heterogeneity. We aimed to study clinical manifestations, long-term complications, molecular basis, and immune profile of patients with dominant CMCD. We identified nine patients with heterozygous mutations in STAT1, including novel amino acid substitutions (L283M, L351F, L400V). High risk of azole-resistance was observed, particularly when intermittent regimens of antifungal treatment or use of suboptimal dosage occurs. We report a case of Cryptococcosis and various bacterial and viral infections. Risk of developing bronchiectasis in early childhood or gradually evolving to chronic lung disease in adolescent or adult ages emerges. Lymphopenia is variable, likely progressing by adulthood. We conclude that continuous antifungal prophylaxis associated to drug monitoring might prevent resistance to treatment; prompt diagnosis and therapy of lung disease might control long-term progression; careful monitoring of lymphopenia-related infections might improve prognosis.

    Converging evidence shows that neurochemical systems are crucial mediators of nicotine dependence. Our present study evaluates the effect of 3-month chronic nicotine treatment on the levels of multiple quaternary ammonium compounds as well as glutamate and gamma aminobutyric acid in the rat prefrontal cortex, dorsal striatum and hypothalamus. We observed a marked decrease of acetylcholine levels in the dorsal striatum (22.88%, p<0.01), reflecting the impact of chronic nicotine in local interneuron circuits. We found decreases of carnitine in the dorsal striatum and prefrontal cortex (19.44%, p<0.01; 13.58%, p<0.01, respectively), but robust enhancements of carnitine in the hypothalamus (26.59%, p<0.01), which may reflect the alterations in food and water intake during chronic nicotine treatment. Finally, we identified an increase of prefrontal cortex glutamate levels (8.05%, p<0.05), supporting previous studies suggesting enhanced prefrontal activity during chronic drug use. Our study shows that quaternary ammonium compounds are regulated in a highly brain region specific manner during chronic nicotine treatment, and provides novel insights into neurochemical regulation during nicotine use.

    Levels of unchanged mescaline were examined in the plasma and brain of albino Swiss-Webster mice pretreated with various doses of either clozapine or molindone. In clozapine treated mice, the mescaline levels were statistically significantly higher at 2 and 3 h with 7.5 and 15.0 mg/kg and at 1, 2 and 3 h with 30 mg/kg. Molindone at 4.0 and 8.0 mg/kg produced no significant effect; at 16.0 and 48.0 mg/kg, the levels were significantly higher at 1 and 2 h. Elevated brain levels of mescaline by clozapine and molindone indicate an adverse metabolic interaction between a hallucinogen and drugs that are commonly used to treat mescaline-induced psychosis.

    Obesity-related genetic variants, including TMEM18 (rs6548238), SH2B1 (rs7498665), and GNPDA2 (rs10938397), have been shown to be associated with obesity in the general population. Our study aimed to test whether these genetic variants are associated with metabolic profiles and metformin treatment response in clozapine-treated schizophrenic patients. We recruited 107 clozapine-treated patients who were genotyped and measured their metabolic profiles. Fifty-five subjects, who had at least 1 metabolic abnormality in a range of measures, were subsequently randomized to a 24-week trial of metformin (n = 28) or placebo (n = 27). We examined the associations between TMEM18, SH2B1, GNPDA2 genetic variants and metabolic profiles at baseline in all patients and metabolic changes in the trial groups. We found a significant association between SH2B1 and blood pressure at baseline in all patients. In the metformin group, TMEM18 minor allele carriers had a greater reduction in insulin levels (P = 0.04). A significantly higher proportion of TMEM18 and GNPDA2 minor allele carriers (60% and 40%) lost more than 7% of their body weight after metformin treatment as compared with their homozygous counterparts (21.7% and 15.4%, P = 0.02 and 0.004, respectively).There were trends toward favorable metabolic changes in minor allele carrier groups. In the placebo group, no association between genetic variants and changes in metabolic profiles was found. In conclusion, the study results suggest that these genes might be associated with metabolic abnormalities and response to metformin in clozapine-treated patients with schizophrenia.

    The role of microorganisms in the etiology and persistence of chronic wounds remains poorly understood. The chronic wound bed houses a complex microenvironment that typically includes more than one bacterial species. Difficulty lies in determining when the presence of bacteria impedes wound healing, thereby warranting intervention. Indications for antibiotic therapy and optimal treatment regimens are ill defined. The goal of this article is to describe the appropriate role of systemic antibiotics in the management of chronic wounds. A common sense approach will be offered based on six clinically pertinent questions: Is infection present? Are systemic antibiotics necessary? Should treatment be enteral or parenteral? What antibiotic or combination of antibiotics should be used? What should be the duration of therapy? What special circumstances are present (i.e., concomitant illnesses, potential drug-drug interactions) that can impact therapy?

    The treatment of this disease with laser such as He-Ne laser, Nd:YAG laser, and CO2 laser, etc., has been applied in our country, but application of the semiconductor laser therapy has received few reports. It has many advantages, such as ting volume, steady function, simple operation (the patient can operate it by himself), no side effects, remarkable results, and it is very convenient. So the semiconductor laser can be used to treat the chronic pharyngitis with irradiation on acupunctural points. One-hundred-twenty chronic pharyngitis patients were divided into 2 groups, a laser group and a medicine group, 60 cases for each. The effective rate is 91.6% and 66.6%, respectively. Obviously the treatment of chronic pharyngitis with semiconductor laser is valuable for widespread use. The principle of the laser therapy is discussed in the last part of this paper.

    The tyrosine kinase inhibitor Imatinib Mesylate has dramatically improved the clinical outcome of chronic myeloid leukemia (CML) patients in the chronic phase of the disease, generating unprecedented rates of complete hematologic and cytogenetic responses and sustained reductions in BCR-ABL transcripts. Here, we present an overview on the efficacy and safety of Imatinib and describe the most important clinical studies employing this drug for the frontline treatment of chronic phase CML. We also discuss recent reports describing the long-term outcome of patients receiving Imatinib for their disease. The imminent availability of generic forms of Imatinib coupled with the approval of expensive second-generation tyrosine kinase inhibitors underlines an unmet need for early molecular parameters that may distinguish CML patients likely to benefit from the drug from those that should receive alternative forms of treatment.

    We describe ultrasound-guided intralesional triamcinolone (ILT) injection for the management of chronic post-operative mammillary fistula (MF). Seven patients with chronic post-operative intraglandular MF were enrolled in this study. The initial response to treatment was assessed as complete in three cases; of the remaining four, three were resolved successfully with an additional ILT injection and the other had no resolution with an additional ILT injection. In five cases there was no recurrence after more than 1 year of follow-up. One patient had recurrence at 7 months, which was treated with a further ILT injection; this patient is without recurrence after a further 9 months' follow-up. This simple, safe procedure is suggested as an option for the treatment of chronic post-operative intraglandular MF and may be an alternative to surgery. PMID:23175497

What antibiotic or combination of antibiotics should be used? What should be the duration of therapy? What special circumstances are present (i.e., concomitant illnesses, potential drug-drug interactions) that can impact therapy? PMID:17199675

    American Trypanosomiasis or Chagas disease (CD) is a neglected disease that affects Latin American people worldwide. Two old antiparasitic drugs, benznidazole and nifurtimox, are currently used for specific CD treatment with limited efficacy in chronic infections and frequent side effects. New drugs are needed for patients with chronic CD as well as for immunosuppressed patients, for whom the risk of reactivation is life-threatening. We describe a case of chronic CD and systemic lupus erythematosus (SLE) that required immunosuppression to control the autoimmune process. It was found that benznidazole induced a reduction, but not an elimination, of circulating Trypanosoma cruzi levels, whereas subsequent treatment with posaconazole led to a successful resolution of the infection, despite the maintenance of immunosuppressive therapy.

    Background Burden of treatment refers to the workload of health care and its impact on patient functioning and well-being. There are a number of patient-reported measures that assess burden of treatment in single diseases or in specific treatment contexts. A review of such measures could help identify content for a general measure of treatment burden that could be used with patients dealing with multiple chronic conditions. We reviewed the content and psychometric properties of patient-reported measures that assess aspects of treatment burden in three chronic diseases, ie, diabetes, chronic kidney disease, and heart failure. Methods We searched Ovid MEDLINE, Ovid EMBASE, Ovid PsycINFO, and EBSCO CINAHL through November 2011. Abstracts were independently reviewed by two people, with disagreements adjudicated by a third person. Retrieved articles were reviewed to confirm relevance, with patient-reported measures scrutinized to determine consistency with the definition of burden of treatment. Descriptive information and psychometric properties were extracted. Results A total of 5686 abstracts were identified from the database searches. After abstract review, 359 full-text articles were retrieved, of which 76 met our inclusion criteria. An additional 22 articles were identified from the references of included articles. From the 98 studies, 57 patient-reported measures of treatment burden (full measures or components within measures) were identified. Most were multi-item scales (89%) and assessed treatment burden in diabetes (82%). Only 15 measures were developed using direct patient input and had demonstrable evidence of reliability, scale structure, and multiple forms of validity; six of these demonstrated evidence of sensitivity to change. We identified 12 content domains common across measures and disease types. Conclusion Available measures of treatment burden in single diseases can inform derivation of a patient-centered measure of the construct in patients with

  14. Clozapine-induced myocarditis may be associated with rapid titration: A case report verified with autopsy.

    Clozapine-induced myocarditis is a poorly understood, rare, potentially fatal adverse drug reaction with absolute risks ranging from 7 to 34 per 1000 in Australia and 0.07-0.6 per 1000 in other countries. Hypersensitivity reactions have been postulated including some cases probably associated with rapid titrations. This case describes a 50-year-old African-American man with schizoaffective disorder, naïve to clozapine, who probably died from clozapine-induced myocarditis. He was started on 25 mg/day of clozapine and received 1625 mg over 14 days, prior to his death on day 15. The autopsy found predominantly lymphocytic infiltrate of the perivascular soft tissue and myocardium of the ventricles, with occasional eosinophils. Using the Liverpool ADR Causality Assessment Tool, it was deemed probable that the patient's death was secondary to myocarditis. The patient had fulminant death with no obvious changes in vital signs. Neither C-reactive protein nor troponin was measured, but it is unlikely that the results would have arrived in time to prevent the patient's death. Age, rapid titration, and concomitant use of valproate contributed to this case, which was probably an idiosyncratic adverse drug reaction associated with rapid titration. Lamotrigine-induced Stevens-Johnson syndrome also appears to be an idiosyncratic adverse drug reaction associated with rapid titration, but its incidence has been remarkably reduced since the recommended starting lamotrigine dose was reduced and corrected by the effect of inhibitors such as valproate. Similarly, clozapine-induced myocarditis incidence probably can be reduced with the use of slow titrations, including even slower titrations for patients with lower ability to metabolize clozapine, such as those taking valproate.

    Selective Serotonin Reuptake Inhibitors (SSRIs) are commonly used drugs for the treatment of psychiatric diseases including major depressive disorder (MDD). For unknown reasons a substantial number of patients do not show any improvement during or after SSRI treatment. We treated DBA/2J mice for 28 days with paroxetine and assessed their behavioral response with the forced swim test (FST). Paroxetine-treated long-time floating (PLF) and paroxetine-treated short-time floating (PSF) groups were stratified as proxies for drug non-responder and responder mice, respectively. Proteomics and metabolomics profiles of PLF and PSF groups were acquired for the hippocampus and plasma to identify molecular pathways and biosignatures that stratify paroxetine-treated mouse sub-groups. The critical role of purine and pyrimidine metabolisms for chronic paroxetine treatment response in the mouse was further corroborated by pathway protein expression differences in both mice and patients that underwent chronic antidepressant treatment. The integrated -omics data indicate purine and pyrimidine metabolism pathway activity differences between PLF and PSF mice. Furthermore, the pathway protein levels in peripheral specimens strongly correlated with the antidepressant treatment response in patients. Our results suggest that chronic SSRI treatment differentially affects purine and pyrimidine metabolisms, which may explain the heterogeneous antidepressant treatment response and represents a potential biosignature.

    While reports suggest a single dose of senolytics may improve vasomotor function, the structural and functional impact of long-term senolytic treatment is unknown. To determine whether long-term senolytic treatment improves vasomotor function, vascular stiffness, and intimal plaque size and composition in aged or hypercholesterolemic mice with established disease. Senolytic treatment (intermittent treatment with Dasatinib + Quercetin via oral gavage) resulted in significant reductions in senescent cell markers (TAF(+) cells) in the medial layer of aorta from aged and hypercholesterolemic mice, but not in intimal atherosclerotic plaques. While senolytic treatment significantly improved vasomotor function (isolated organ chamber baths) in both groups of mice, this was due to increases in nitric oxide bioavailability in aged mice and increases in sensitivity to NO donors in hypercholesterolemic mice. Genetic clearance of senescent cells in aged normocholesterolemic INK-ATTAC mice phenocopied changes elicited by D+Q. Senolytics tended to reduce aortic calcification (alizarin red) and osteogenic signaling (qRT-PCR, immunohistochemistry) in aged mice, but both were significantly reduced by senolytic treatment in hypercholesterolemic mice. Intimal plaque fibrosis (picrosirius red) was not changed appreciably by chronic senolytic treatment. This is the first study to demonstrate that chronic clearance of senescent cells improves established vascular phenotypes associated with aging and chronic hypercholesterolemia, and may be a viable therapeutic intervention to reduce morbidity and mortality from cardiovascular diseases.

    Background and aim Ketamine is a drug used for the induction and maintenance of general anesthesia, for the treatment of postoperative and posttraumatic acute pain, and more recently, for the reduction of postoperative opioid requirements. The main mechanism of action of ketamine is the antagonization of N-methyl-D-aspartate (NMDA) receptors that are associated with central sensitization. In the pathogenesis of chronic pain and particularly in neuropathic pain, an important role is played by the activation of NMDA receptors. Although ketamine is indicated and used for the treatment of chronic cancer pain as an adjuvant to opioids, there are few clinical studies that clearly demonstrate the effectiveness of ketamine in this type of pain. The aim of this study is to analyze evidence-based clinical data on the effectiveness and safety of ketamine administration in the treatment of chronic neoplastic pain, and to summarize the evidence-based recommendations for the use of ketamine in the treatment of chronic cancer pain. Method We reviewed the literature from the electronic databases of MEDLINE, COCHRANE, PUBMED, MEDSCAPE (1998–2014), as well as chapters of specialized books (palliative care, pain management, anesthesia). Results A number of studies support the effectiveness of ketamine in the treatment of chronic cancer pain, one study does not evidence clear clinical benefits for the use of ketamine, and some studies included too few patients to be conclusive. Conclusions Ketamine represents an option for neoplasic pain that no longer responds to conventional opioid treatment, but this drug should be used with caution, and the development of potential side effects should be carefully monitored.

    Accurate diagnosis and treatment rates for chronic hepatitis B (HBV) and C virus (HCV) infections are usually missing. Aim of this study was to estimate the HBV and HCV treatment cascade (proportion and absolute numbers of tested, aware/unaware, infected and treated) in Greek adults. A telephone survey was conducted in a sample representative of the Greek adult general population. Prevalence rates were age-standardized for the Greek adult population and corrected for high-risk individuals not included in the survey. Of the 9974 participants, 5255 (52.7%) had been tested for HBV and 2062 (20.7%) for HCV with the proportion varying according to age and being higher in middle-age groups (P < 0.001). HBsAg was reported positive in 111/5255 (2.11%) and anti-HCV in 26/2062 (1.26%) tested cases. The age-adjusted prevalence was estimated to be 2.39% for HBV and 1.79% for HCV. Taking into account individuals at high risk for viral hepatitis not included in the survey, the 'true' prevalence was estimated to be 2.58% for HBV and 1.87% for HCV. Anti-HBV and anti-HCV treatment had been taken by 36/111 (32.4%) chronic HBV and 15/26 (57.7%) chronic HCV patients. In conclusion, almost 50% of chronic HBV and 80% of chronic HCV patients in Greece may be unaware of their infection, while only 32% or 58% of diagnosed chronic HBV or HCV patients, respectively, have been ever treated. Therefore, intensive efforts are required to improve the efficacy of screening for HBV and particularly for HCV as well as to reduce the barriers to treatment among diagnosed patients. PMID:25209157

    To gain insight into the possible immune targets of antidepressant, we evaluated the expression of several inflammatory mediators in the hypothalamus of rats chronically (28 days) treated with the serotonin selective reuptake inhibitor fluoxetine (5mg/kg, i.p.) or the tricyclic compound imipramine (15 mg/kg, i.p.). We focused our attention on the hypothalamus as it plays a key role in determining many of the somatic symptoms experienced by depressed patients. This brain region, critical also for expression of motivated behaviours, participates in the control of the hypothalamic-pituitary-adrenal axis activity and in stress response as well as coordinates physiological functions such as sleep and food intake that have been found altered in a high percentage of depressed patients. Notably, hypothalamus is a key structure for brain cytokine expression and function as it integrates signals from the neuro, immune, endocrine systems. By means of quantitative Real Time PCR experiments we demonstrated that a chronic treatment with either fluoxetine or imipramine resulted in a reduction of IL-6 and IFN-γ mRNAs and increased IL-4 mRNA expression in the rat hypothalamus. Moreover, we demonstrated that hypothalamic expression of members of IL-18 system was differentially affected by chronic antidepressant treatments. Chronically administered fluoxetine decreased IL-8 and CX3CL1 hypothalamic expression, while a chronic treatment with imipramine decreased p11 mRNA. Our data suggest that a shift in the balance of the inflammation toward an anti-inflammatory state in the hypothalamus may represent a common mechanism of action of both the chronic treatments with fluoxetine and imipramine.

    This review article was requested by editor-in-chief of this journal as ‘pediatric CHB treatment’ for the upcoming special issue. The main objective of chronic hepatitis B (CHB) treatment is diminishing the risk of complications related to chronic liver disease. In Asia, there are already some reports about hepatocellular carcinoma (HCC) in hepatitis B virus (HBV) infected children. The key points of treatment in children with CHB infections are selection of which patients to treat and conformation of the optimal therapy time that would reduce viral resistance. The choice of therapy is determined by the district (Western/Eastern), HBV genotype, medical accessibility, and economic state of the country. Newly developed nucleos(t)ide analogues (NAs) are potent in children with CHB. However, to improve therapeutic efficacy, physicians are recommended to follow treatment guidelines and determine the specific genotype in the CHB patient. In this article, the treatment of pediatric CHB is reviewed according to differences in genotype.

    Prenatal stress can cause many long-term behavior changes in offspring, but whether prenatal stress can alter addictive behavior in offspring and postnatal enriched environment treatment (EE) can restore these changes are unknown. We reported here that prenatal chronic stress (10 unpredictable, 1 s, 0.8 mA foot-shocks per day during gestational days 13-19) enhanced morphine-induced (10 mg/kg, s.c., per day, 6 consecutive days) place preference. Moreover, prenatal chronic stress caused higher depressive-like behavior in forced swimming test in adult offspring. However, enriched environment housing treatment on postnatal days 22-52 counteracted both the abnormal behaviors alterations. This work observed a phenomenon that might contribute to the understanding of clinically important interactions among addiction, prenatal stress and enriched environment treatment. Postnatal enriched environment treatment might be an important therapeutic intervention in preventing the prenatal stress-induced addictive disorders.

    Patients with a history of chronic self-destructive and self-injurious behavior present many difficulties to healthcare providers. These patients often have related substance abuse and personality disorders that complicate their medical care. Treatment encounters initially may be related to medical treatment of episodic substance intoxicated states with or without self-inflicted injuries. Patients later can develop comorbid medical illnesses associated with nonadherence of treatment or iatrogenic conditions, both of which result in complex end-of-life-care decisions. Institutional familiarity of repeat patients often leaves healthcare providers feeling responsible for the patient despite having little influence over the patients' ultimate behavioral outcomes. This article describes a patient with chronic alcohol abuse, treatment noncompliance, severe personality disorder, recurrent suicidal ideation, self-injurious behavior, alcoholic cirrhosis, and suicide attempt resulting in multisystem injuries leading to an ethical conflict regarding end-of-life care.

    The application of laser therapy on soft tissue is used for pain relief, anti-inflammation action and biostimulation. The efficiency of High Energy Laser Therapy has not yet been studied on Achilles tendinopathy. The aim of the study is to evaluate the effectiveness of a flow of Cold air and High Energy Laser Therapy (CHELT) versus Extracorporeal Shock Waves Therapy (ESWT) in the treatment of Achilles tendinopathy. In this prospective, clinical trial, 60 subjects affected by insertional Achilles tendinopathy were enrolled and randomized to CHELT (30 subjects) or to ESWT (30 subjects). In CHELT group the patients received ten daily sessions of 1,200 J and 12 W of laser therapy (wavelength of 1,084, 810 and 980 nm) added to a flow of cold air at -30 °C. In the ESWT group, the patients received three sessions at 3- to 4-day intervals of 1,600 impulses with an energy flux density (EFD) of 0.05-0.07 mJ/mm(2). Both groups of participants performed stretching and eccentric exercises over a 2-month period. The visual analogue scale (VAS), the Ankle-Hindfoot Scale, and the Roles and Maudsley Score were measured before treatment (T0), and at end of the treatment session (T1) and 2 (T2) and 6 months (T3) after treatment during the follow-up examinations. In both groups, we found a statistically significant improvement of the VAS at T1, T2 and T3 (p < 0.01). The difference between the two groups was statistically significant in favour of the CHELT group (p < 0.001). At 2 months, the CHELT group was statistically better for Ankle-Hindfoot Scale and the Roles and Maudsley Score (p < 0.05) and at 6 months only for the Roles and Maudsley Score (p < 0.001). High Energy Laser Therapy gave quicker and better pain relief. It also gave the patient a full functional recovery and greater satisfaction.

    Purpose: The purpose of this study is to evaluate the effectiveness of chronic suppurative lacrimal canaliculitis treatment using chalazion forceps. Patients and Methods: A prospective study was performed on consecutive patients who accepted the aid of chalazion forceps to treat chronic suppurative lacrimal canaliculitis. Two different treatment methods using chalazion forceps were performed according to the degree of lacrimal canaliculitis. Postoperatively, the patients received 0.5% levofloxacin eye drops four times per day and 0.5 g oral levofloxacin tablets once per day for 4 days. The follow-up period was more than 3 months. Lacrimal irrigation, the condition of the lacrimal punctum, and patients’ symptoms were carefully evaluated. Results: In total, 32 patients met the criteria for chronic suppurative lacrimal canaliculitis. Included were 6 males and 26 females. Their average age was 51.7 ± 14.9 years (range; 19–80 years), and all had unilateral canaliculitis. The mean duration of the symptoms was 18.9 ± 9.8 months (range; 3–48 months). The mean follow-up time was 14.7 ± 7.8 months. The signs and symptoms resolved completely in all patients within 15 days, and no recurrence was observed. No patients reported epiphora after the treatment. Conclusions: The use of chalazion forceps is effective in treating chronic suppurative lacrimal canaliculitis. The forceps may offer an alternative treatment technology in the management of suppurative lacrimal canaliculitis. PMID:27688281

    Chronic cough is a very common complaint in clinics throughout China. Clinical and basic science research on chronic cough started late, but in recent years the effort has yielded promising findings regarding the etiological diagnosis, treatment and pathogenesis. We found that inflammation in nonasthmatic eosinophilic bronchitis has some similarities to cough variant asthma but also a number of distinct differences. Recent evidence has also suggested a mechanistic link between airway neurogenic inflammation and and gastroesophageal reflux cough (GERC). Cough-related animal models have been developed, including models for esophageal reflux, nonasthmatic eosinophilic bronchitis and allergic rhinitis. Normal reference values for differential cell counts in induced sputum, cough sensitivity and esophageal 24-h pH monitoring in Chinese healthy subjects have been established. By using a modified algorithm for the etiological diagnosis of chronic cough, the causes of chronic cough have been investigated across a number of cities in China. The most common causes of chronic cough are cough variant asthma, eosinophilic bronchitis, upper airway cough symptoms, atopic cough and GERC, however, there are some regional variations. The Chinese National Guidelines on Diagnosis and Management of Chronic Cough were drafted in 2005, updated in 2009, and have been widely publicized and disseminated through many channels since their publication.

    2005-03-23

    Delta-opioid receptor (DOPr) activation fails to produce cellular physiological responses in many brain regions, including the periaqueductal gray (PAG), despite neural expression of high densities of the receptor. Previous histochemical studies have demonstrated that a variety of stimuli, including chronic morphine treatment, induce the translocation of DOPr from intracellular pools to the surface membrane of CNS neurons. PAG neurons in slices taken from untreated mice exhibited mu-opioid receptor (MOPr) but not DOPr-mediated presynaptic inhibition of GABAergic synaptic currents. In contrast, after 5-6 d of chronic morphine treatment, DOPr stimulation inhibited synaptic GABA release onto most neurons. Shorter exposure to morphine in vitro (upto 4 h) or in vivo (18 h) did not induce functional DOPr responses. DOPr-mediated presynaptic inhibition could not be induced in slices from untreated animals by increasing synaptic activity in vitro using high extracellular potassium concentrations or activation of protein kinase A. Induction of functional DOPr signaling by chronic morphine required MOPr expression, because no DOPr receptor responses were observed in MOPr knock-out mice. DOPr agonists also had no effect on miniature IPSCs in beta-arrestin-2 knock-out mice after chronic morphine. These results suggest that induction of DOPr-mediated actions in PAG by chronic morphine requires prolonged MOPr stimulation and expression of beta-arrestin-2.

    The purpose of this study was to identify whether veterans with chronic pain, substance abuse, and posttraumatic stress disorder (PTSD) diagnoses residing in a Residential Rehabilitation Treatment Program (RRTP) perceived a higher level of pain than those veterans who had chronic pain but did not have active substance abuse issues or PTSD. A sample of veterans (n = 200) with chronic pain undergoing treatment for either chemical dependency and/or PTSD in an RRTP and a Surgical Specialty Care outpatient clinic at a Department of Veterans Affairs medical center took part in the study. Multiple analysis of variance and further univariate statistics were examined to determine the association between groups on the different scales. There was a considerable difference in terms of which group of veterans perceived a higher rate of pain even with the use of the same four pain assessment scales (i.e., Numeric Rating, Visual Analog, Faces, and Mankoski). Scores were significantly higher for the RRTP group than the Surgical Specialty Care group on all screening measures (p < .001). Veterans with chronic pain, substance abuse, and/or PTSD diagnoses residing in an RRTP tended to have a higher perception of chronic pain compared to those without substance abuse or PTSD diagnoses.

    Chronic dialysis replacement treatments or renal transplants are instituted when the patient's glomerular filtration rate, measured by 24-h urine endogenous creatinine clearance, is <10-15 ml/mm and, as the The National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF KDOQI), European and Canadian guidelines point out, when one or two of the following complications occur: "uremic toxicity" symptoms, significant fluid retention that does not respond to loop diuretics, hyperkalemia, chronic anemia (hemoglobin <8 g), metabolic acidosis or acute pulmonary edema. In all patients for whom transplant is indicated, a selected live donor must be sought or, in the absence of contraindications, the patient should be registered with the national cadaver donation waiting list. While waiting for the transplant, patients will be on a chronic dialysis program. There is no national registry of patients undergoing chronic dialysis; only indirect data from the Mexican Kidney Foundation and the dialysis industry are available. However, it is estimated that 40,000-50,000 people are under this treatment and the numbers grow by 11% every year. Overall, it is thought that for every patient receiving chronic dialysis, there is one more patient who dies without access to therapy. Hemodialysis units must comply with the Official Hemodialysis Standard and the General Health Council Hemodialysis Unit Quality Assessment Form.

    The effects of acute and chronic administration of tianeptine, a novel antidepressant agent, on the hypothalamo-pituitary-adrenal axis were studied in the adult male rat. A single injection of tianeptine did not alter the activity of the hypothalamo-pituitary-adrenal axis. In contrast, chronic administration of tianeptine (10 mg/kg twice a day for 15 days) induced a significant decrease in the concentration of corticotropin-releasing factor (CRF) in the hypothalamus and adrenocorticotropin (ACTH) in the anterior lobe of the pituitary. Chronic tianeptine treatment did not modify CRF levels in the cerebral cortex and hippocampus, and did not alter alpha-melanocyte-stimulating hormone and beta-endorphin levels in the neurointermediate lobe of the pituitary. Using the in situ hybridization technique, we observed that chronic administration of tianeptine did not modify CRF mRNA levels in the paraventricular nucleus of the hypothalamus. The effect of chronic tianeptine treatment on the neuroendocrine response to stress was also investigated. Tube restraint stress for 30 min induced a significant depletion of hypothalamic CRF and a substantial increase of plasma ACTH and corticosterone. Tianeptine abolished the stress-induced reduction of hypothalamic CRF concentration and markedly reduced the stress-induced increase in plasma ACTH and corticosterone levels. Taken together, these results suggest that tianeptine acts primarily at the level of the hypothalamus: (1) in unstressed rats, tianeptine reduces hypothalamic CRF and pituitary ACTH contents; (2) in stressed animals, tianeptine attenuates the activation of the hypothalamo-pituitary-adrenal axis.

    Objectives To determine the feasibility of conducting a randomized clinical trial designed to compare two methods of manual therapy (myofascial physical therapy (MPT) and global therapeutic massage (GTM)) among patients with urologic chronic pelvic pain syndromes. Materials and Methods Our goal was to recruit 48 subjects with chronic prostatitis/chronic pelvic pain syndrome or interstitial cystitis/painful bladder syndrome at six clinical centers. Eligible patients were randomized to either MPT or GTM and were scheduled to receive up to 10 weekly treatments, each 1 hour in duration. Criteria to assess feasibility included adherence of therapists to prescribed therapeutic protocol as determined by records of treatment, adverse events which occurred during study treatment, and rate of response to therapy as assessed by the Patient Global Response Assessment (GRA). Primary outcome analysis compared response rates between treatment arms using Mantel-Haenszel methods. Results Twenty-three (49%) men and 24 (51%) women were randomized over a six month period. Twenty-four (51%) patients were randomized to GTM, 23 (49%) to MPT; 44 (94%) patients completed the study. Therapist adherence to the treatment protocols was excellent. The GRA response rate of 57% in the MPT group was significantly higher than the rate of 21% in the GTM treatment group (p=0.03). Conclusions The goals to judge feasibility of conducting a full-scale trial of physical therapy methods were met. The preliminary findings of a beneficial effect of MPT warrants further study.

    There is evidence for the efficacy of acupuncture treatment for chronic shoulder pain, but it remains unclear which acupuncture modes are most effective. We compared the effect of trigger point acupuncture (TrP), with that of sham (SH) acupuncture treatments, on pain and shoulder function in patients with chronic shoulder pain. The participants were 18 patients (15 women, 3 men; aged 42-65 years) with nonradiating shoulder pain for at least 6 months and normal neurological findings. The participants were randomized into two groups, each receiving five treatment sessions. The TrP group received treatment at trigger points for the muscle, while the other group received SH acupuncture treatment on the same muscle. Outcome measures were pain intensity (visual analogue scale, VAS) and shoulder function (Constant-Murley Score: CMS). After treatment, pain intensity between pretreatment and 5 weeks after TrP decreased significantly (p<0.001). Shoulder function also increased significantly between pretreatment and 5 weeks after TrP (p<0.001). A comparison using the area under the outcome curves demonstrated a significant difference between groups (p=0.024). Compared with SH acupuncture therapy, TrP therapy appears more effective for chronic shoulder pain.
