Sensitive method for the simultaneous measurement of fluphenazine decanoate and fluphenazine in plasma by high-performance liquid chromatography with cuolometric detection

A highly sensitive and specific high-performance liquid chromatographic method with coulometric detection was developed for the simultaneous assay of fluphenazine decanoate and fluphenazine in plasma. The extraction and sample clean-up procedures are simple, rapid to execute, yet yield chromatograms relatively free of any interference from endogenous plasma constituents, such that the extraordinary sensitivity of the coulometric detector can be exploited fully. This is the first analytical procedure for the simultaneous determination of fluphenazine decanoate and fluphenazine. The detection limits for both fluphenazine decanoate and fluphenazine were 0.1 ng/ml plasma and the limits of quantitation were 0.25 ng/ml plasma. Standard curves from 0.25 to 10 ng/ml were linear with coefficients of variation <10%. The method was applied to measure plasma levels of fluphenazine decanoate and fluphenazine in patients under medication with 25–50 mg biweekly intramuscular (i.m.) injections of fluphenazine decanoate. It was possible to monitor the plasma levels of fluphenazine in all cases. Fluphenazine decanoate was present in measurable concentration in the plasma of 4 out of 5 patients who received biweekly i.m. injections of 50 mg fluphenazine decanoate. In a pilot experiment with a dog, the method was used to follow fluphenazine decanoate and fluphenazine plasma levels up to 13 days, at least, after i.m. single dose (10 mg/kg).

Risk of Bias from Inclusion of Currently Diagnosed or Treated Patients in Studies of Depression Screening Tool Accuracy: A Cross-Sectional Analysis of Recently Published Primary Studies and Meta-Analyses

Background

Depression screening can improve upon usual care only if screening tools accurately identify depressed patients who would not otherwise be recognized by healthcare providers. Inclusion of patients already being treated for depression in studies of screening tool accuracy would inflate estimates of screening accuracy and yield. The present study investigated (1) the proportion of primary studies of depression screening tool accuracy that were recently published in journals listed in MEDLINE, which appropriately excluded currently diagnosed or treated patients; and (2) whether recently published meta-analyses identified the inclusion of currently diagnosed or treated patients as a potential source of bias.

Methods

MEDLINE was searched from January 1, 2013 through March 27, 2015 for primary studies and meta-analyses on depression screening tool accuracy.

Results

Only 5 of 89 (5.6%) primary studies excluded currently diagnosed or treated patients from any analyses and only 3 (3.4%) from main analyses. In 3 studies that reported the number of patients excluded due to current treatment, the number of excluded patients was more than twice the number of newly identified depression cases. None of 5 meta-analyses identified the inclusion of currently diagnosed and treated patients as a potential source of bias.

Conclusions

The inclusion of currently diagnosed and treated patients in studies of depression screening tool accuracy is a problem that limits the applicability of research findings for actual clinical practice. Studies are needed that evaluate the diagnostic accuracy of depression screening tools among only untreated patients who would potentially be screened in practice.     

Outpatient Maintenance of Chronic Schizophrenic Patients with Long-acting Fluphenazine: Double-blind Placebo

A double-blind placebo trial of fluphenazine decanoate, a long-acting phenothiazine, was carried out to determine its value in maintenance therapy of chronic schizophrenic outpatients already established on the drug for a minimum period of eight weeks. In low doses it was significantly more effective than placebo in preventing relapse and admission to hospital. Relapse was accompanied by a resurgence of specifically schizophrenic symptoms and by an increase in abnormalities described by the relatives. There was no difference between the experimental and control groups in the treatment required for depression. The group on active medication required more treatment for Parkinsonism, but this difference did not reach statistical significance.In the context of a well-run special clinic for outpatient follow-up of chronic schizophrenic patients these results confirm the usefulness of long-acting fluphenazine. By inference, the benefit of this treatment highlights the need for adequate community services to deal with the residual chronic disabilities which are characteristic of these patients.

Psychological outcomes of different treatment policies in women with early breast cancer outside a clinical trial.

OBJECTIVES--To assess outside a clinical trial the psychological outcome of different treatment policies in women with early breast cancer who underwent either mastectomy or breast conservation surgery depending on the surgeon''s opinion or the patient''s choice. To determine whether the extent of psychiatric morbidity reported in women who underwent breast conservation surgery was associated with their participation in a randomised clinical trial. DESIGN--Prospective, multicentre study capitalising on individual and motivational differences among patients and the different management policies among surgeons for treating patients with early breast cancer. SETTING--12 District general hospitals, three London teaching hospitals, and four private hospitals. PATIENTS--269 Women under 75 with a probable diagnosis of stage I or II breast cancer who were referred to 22 different surgeons. INTERVENTIONS--Surgery and radiotherapy or adjuvant chemotherapy, or both, depending on the individual surgeon''s stated preferences for managing early breast cancer. MAIN OUTCOME MEASURES--Anxiety and depression as assessed by standard methods two weeks, three months, and 12 months after surgery. RESULTS--Of the 269 women, 31 were treated by surgeons who favoured mastectomy, 120 by surgeons who favoured breast conservation, and 118 by surgeons who offered a choice of treatment. Sixty two of the women treated by surgeons who offered a choice were eligible to choose their surgery, and 43 of these chose breast conserving surgery. The incidences of anxiety, depression, and sexual dysfunction were high in all treatment groups. There were no significant differences in the incidences of anxiety and depression between women who underwent mastectomy and those who underwent lumpectomy. A significant effect of surgeon type on the incidence of depression was observed, with patients treated by surgeons who offered a choice showing less depression than those treated by other surgeons (p = 0.06). There was no significant difference in psychiatric morbidity between women treated by surgeons who offered a choice who were eligible to choose their treatment and those in the same group who were not able to choose. Most of the women (159/244) gave fear of cancer as their primary fear rather than fear of losing a breast. The overall incidences of psychiatric morbidity in women who underwent mastectomy and those who underwent lumpectomy were similar to those found in the Cancer Research Campaign breast conservation study. At 12 months 28% of women who underwent mastectomy in the present study were anxious compared with 26% in the earlier study, and 27% of women in the present study who underwent lumpectomy were anxious compared with 31% in the earlier study. In both the present and earlier study 21% of women who underwent mastectomy were depressed, and 19% of women who underwent lumpectomy in the present study were depressed compared with 27% in the earlier study.) CONCLUSIONS--There is still no evidence that women with early breast cancer who undergo breast conservation surgery have less psychiatric morbidity after treatment than those who undergo mastectomy. Women who surrender autonomy for decision making by agreeing to participate in randomised clinical trials do not experience any different psychological, sexual, or social problems from those women who are treated for breast cancer outside a clinical trial.

Genetic Prediction of Antidepressant Drug Response and Nonresponse in Korean Patients

Genetic polymorphism contributes to variation in response to drug treatment of depression. We conducted three independent 6-week treatment studies in outpatients with major depressive disorder (MDD) to develop a pharmacogenomic model predicting response and nonresponse. We screened candidate genomic markers for association with response to selective serotonin reuptake inhibitors (SSRIs). No patients had received any antidepressant drug treatment in the current episode of depression. Outcome evaluation was blinded to drug and genotype data. The prediction model derived from a development sample of 239 completer cases treated with SSRIs comprised haplotypes and polymorphisms related to serotonin synthesis, serotonin transport, glutamate receptors, and GABA synthesis. The model was evaluated prospectively for prediction of outcome in a validation sample of 176 new SSRI-treated completer cases. The model gave a prediction in 60% of these cases. Predictive values were 85% for predicted responders and 86% for predicted nonresponders, compared to prior probabilities of 66% for observed response and 34% for observed nonresponse in those cases (both P<0.001). Convergent cross-validation was obtained through failure of the model to predict outcomes in a third independent sample of 189 completer cases who received non-SSRI antidepressants. We suggest proof of principle for genetic guidance to use or avoid SSRIs in a majority of Korean depressed patients.     

Severe euthyroid cardiac disease; technique for treatment with radioiodine

It is possible to safely lower the basal metabolism of patients suffering from severe cardiac disease by administering multiple small doses of radioiodine in order to achieve symptomatic relief. From the present study, multiple small doses of I(131) appeared to be as effective as single or multiple large doses of this material and complications such as thyroiditis, temporary thyrotoxicosis and bone marrow depression were almost always avoided. No damage to the parathyroid glands or the recurrent laryngeal nerve was observed. No radiation sickness developed after therapy.A scintigram of the thyroid gland was useful in determining the size, shape and function of the thyroid gland before and during radioiodine treatment and helped to determine the need for additional treatment. In order to prevent the distressing symptoms of the myxedema state, desiccated thyroid was administered when necessary. In the series of 278 euthyroid patients with severe cardiac disease who were treated with radioactive iodine, results were excellent in 35 per cent of cases and good in 44 per cent. In 21 per cent there was no improvement.

Combined antibiotic therapy of acute radiation disease in persons affected during the accident at the Chernobyl nuclear power station

One hundred and fifteen patients with acute radiation disease of degrees I to IV affected during the accident at the Chernobyl APS were treated in a specialized hospital. The anti-infection regimen included isolation, air sterilization with ultraviolet light, intravenous administration of broad spectrum of antibiotics (gentamicin, cephalosporins and carbenicillin) and nystatin. Some cases were treated with amphotericin. Some cases were treated with amphotericin B. Out of 22 patients who died at the early periods (days 14 to 34) or at the period of agranulocytosis in 7 patients sepsis was stated. In 5 of them it was complicated by pneumonia. In 5 patients who died at the late periods (days 48 to 99) or at the period of hemopoiesis normalization infectious complications by the death moment were stated: sepsis in 3 patients and pneumonia in 2 patients. The aspect of the microbiological diagnosis and therapy efficacy is discussed.     

DNA repair of hydrogen peroxide-induced damage in human lymphocytes in the presence of four antimutagens. A study with alkaline single cell gel electrophoresis (comet assay).

We assessed four antimutagenic compounds' influences on DNA repair in human lymphocytes exposed in vitro to hydrogen peroxide (20 microM, 5 min, at 4 degrees C). DNA damage and repair were estimated by means of alkaline single cell gel electrophoresis (comet assay). It was noticed that the enhancement of DNA repair was relatively strongest when fluphenazine was present in the cell culture medium. In the cases of anthocyanins and alkylresorcinols, the effects were almost 6-9 times weaker than that of FPh. The effect of todralazine on DNA repair was relatively weakest. Further study should be done on fluphenazine as a potential DNA repair-enhancing compound.
