RESUMO

BACKGROUND: In 2011, direct healthcare professional communication (DHPC) letters on citalopram and escitalopram were sent out to address the risk of QTc prolongation in the ECG. Healthcare professionals were informed about a reduction of the maximum recommended daily dose. Furthermore, a contraindication for QTc-prolonging co-medication was given. Previous studies noted that these instructions were implemented incompletely. AIM: For the first time, this study analyzed how the DHPC affected the prescription of citalopram and escitalopram in patients with anxiety disorders. METHODS: Drug utilization data from the project "Arzneimittelsicherheit in der Psychiatrie e. V." (AMSP) was used to examine whether the proportion of patients treated with a higher-than-recommended daily dose ("high dose") and the proportion of patients with QTc-prolonging co-medication would decrease post-DHPC (combined category of citalopram/escitalopram). RESULTS: Drug utilization data of n = 364 patients pre- and n = 262 patients post-DHPC were compared. The proportion of patients with high dose declined from 10.7% to 5.4% (p = 0.019). The proportion of patients with QTc-prolonging co-medication did not change significantly from pre- (54.7%) to post-DHPC (51.5%, p = 0.437). DISCUSSION: In accordance with previous studies, the proportion of high-dose patients decreased after DHPC publication while the proportion of patients with QTc-prolonging co-medication remained widely unchanged. The specific recommendation on daily dosage seems to have been better implemented than the broadly formulated contraindication of QTc-prolonging co-medication. Hence, DHPCs should be written precisely and give advice for specific clinical situations.

RESUMO

OBJECTIVES: Drug-induced liver injury (DILI) has been associated with various antipsychotic drugs (APDs). Comparative studies between individual APDs are largely not available. METHODS: Antipsychotic drug utilisation data and reports of severe antipsychotic DILI were assessed by using data from an observational pharmacovigilance programme-Arzneimittelsicherheit in der Psychiatrie (AMSP)-during the period 1993-2016. RESULTS: Of the 333,175 patients treated with APDs, a total of 246 (0.07%) events of severe DILI were identified. Phenothiazines were associated with significantly higher rates of severe DILI (0.03%, 95% CI = 0.02-0.04) than thioxanthenes (0.01%, 95% CI = 0.00-0.02) or butyrophenones (0.01%, 95% CI = 0.00-0.01). Among individual drugs, olanzapine (0.12%, 95% CI = 0.10-0.16), perazine (0.09%, 95% CI = 0.05-0.15) and clozapine (0.09%, 95% CI = 0.10-0.12 ranked highest. In 78 cases (31.7%), combination therapies with antipsychotic and antidepressant drugs or with two or more APDs were considered responsible. Male sex and a diagnosis of mania were associated with significantly higher rates of severe DILI while older patients (≥65 years old) were significantly less often affected. CONCLUSIONS: In the present analysis of a representative psychiatric inpatient cohort, olanzapine, perazine, and clozapine were the most common individual APDs associated with severe DILI.

RESUMO

BACKGROUND: Psychotropic drugs are the cornerstone of schizophrenia treatment, often requiring lifelong treatment. Data on pharmacotherapy in inpatient settings are lacking. METHODS: Prescription data of schizophrenic inpatients within the time period 2000-2015 were obtained from the database of the Drug Safety Program in Psychiatry (AMSP). Data were collected at 2 index dates per year; the prescription patterns and changes over time were analyzed. RESULTS: Among 30 908 inpatients (mean age 41.6 years, 57.8% males), the drug classes administered most often were antipsychotics (94.8%), tranquilizers (32%), antidepressants (16.5%), antiparkinsonians (16%), anticonvulsants (14.1%), hypnotics (8.1%), and lithium (2.1%). The use of second-generation antipsychotics significantly increased from 62.8% in 2000 to 88.9% in 2015 (P < .001), whereas the prescription of first-generation antipsychotics decreased from 46.6% in 2000 to 24.7% in 2015 (P < .001). The administration of long-acting injectable antipsychotics decreased from 15.2% in 2000 to 11.7% in 2015 (P = .006). Clopazine was the most often used antipsychotic, having been used for 21.3% of all patients. Polypharmacy rates (≥5 drugs) increased from 19% in 2000 to 26.5% in 2015. Psychiatric polypharmacy (≥3 psychotropic drugs) was present in 44.7% of patients. CONCLUSIONS: Combinations of antipsychotics and augmentation therapies with other drug classes are frequently prescribed for schizophrenic patients. Though treatment resistance and unsatisfactory functional outcomes reflect clinical necessity, further prospective studies are needed on real-world prescription patterns in schizophrenia to evaluate the efficacy and safety of this common practice.

RESUMO

Patients with schizophrenia suffer from stigma and discrimination due to their illness. Yet it is not well examined how experiences of stigma and discrimination express at the early illness stage and how they develop subsequently. Therefore, clinical and psycho-social correlates of stigma experiences and perceived stigma are analyzed in patients with first-episode schizophrenia over the course of 1 year after their first in-patient treatment. Questionnaire data assessed within the multi-centre-RCT "First-Episode Study" of the German Research Network on Schizophrenia were analyzed. Patients with first-episode schizophrenia were assessed 8 weeks after their first in-patient treatment (post-acute assessment) and 1 year later. N = 48 (post-acute) and N = 24 (1-year follow-up) patients provided questionnaire data appropriate for analyses, with N = 12 dyads. These data included burden due to stigma experiences (B-STE), perceived stigma (PDDQ), clinical (PANSS, CDSS, CGI, GAF, SAS) and psycho-social factors (LQLP, FSNK-self-esteem, KK-Scale). Cross-lag-correlation models showed a causal relation between stigma experiences (post-acute) and reduced self-esteem after 1 year. Multiple regression models revealed different models for experienced and perceived stigma. Factors associated with higher stigma experiences were older age, worse clinical global impression, better social adjustment, lower self-esteem, and the belief that illness is not driven by chance or fate. The different associations between psycho-social factors and stigma experiences and perceived stigma demonstrate the complexity of this inter-relationship. The results have practical implications for psycho-educational and other therapeutic interventions addressing stigma coping. Since the sample was small and selective, replication studies are needed.

RESUMO

Thyroid diseases are often associated with psychiatric disorders. The prevalence of autoimmune thyroiditis in the general population is estimated to be at about 5-14 %. A clinical study was conducted to evaluate the association between autoimmune thyroiditis and depression in psychiatric outpatients. Fifty-two patients with depression and nineteen patients with schizophrenia (serving as control group), attending a psychiatric outpatient unit, were included. In addition to the measurement of thyroid-stimulating hormone (TSH), free triiodothyronine, free thyroxine, antithyroid peroxidase (anti-TPO) antibodies, and anti-thyroglobulin antibodies, ultrasound examination of the thyroid gland was performed. The proportion of pathologically increased anti-TPO levels in patients with depression was high. Furthermore, the distribution of pathologically increased anti-TPO levels was significantly (χ (2) = 5.5; p = 0.019) different between patients with depression (32.7 %) and patients with schizophrenia (5.3 %). In a gender- and age-adjusted logistic regression, the odds ratio of uni- or bipolar patients with depression for an autoimmune thyroiditis was ten times higher (95 % CI = 1.2-85.3) when compared with schizophrenia patients. TSH basal level did not differ between patients with depression and patients with schizophrenia. Our study demonstrates a strong association between anti-TPO levels, which are considered to be of diagnostic value for autoimmune thyroiditis (in combination with a hypoechoic thyroid in ultrasonography) with uni- or bipolar depression. It should be noted that the routinely measured TSH level is not sufficient in itself to diagnose this relevant autoimmune comorbidity.

RESUMO

The majority of opioid dependent patients suffer from various psychiatric and somatic comorbid diseases like mood and anxiety disorders, psychotic diseases, personality disorders, HIV infection, Hepatitis B and C. If medical treatment is needed, grouping active substances to FDA Pregnancy Categories (A, B, C, D or X) may be helpful. The majority of substances reported here only fulfill the FDA-categories C or D, which means that they could have teratogenic effects, but with probably different rank order. First of all, referring to mood, personality and anxiety disorders, the focus should be laid on non-pharmacological treatment by offering psychotherapeutic and supporting psychosocial interventions to the patients. However, opioid dependent pregnant patients who suffer from severe diseases such as psychosis, bipolar affective disorder or severe depression, may need psychoactive medication like antipsychotics, antidepressants or mood stabilizers to prevent them from harm caused by psychotic ideas and actions and/or suicidality. However these medications may comprise fetal risks, especially when taken together, and therefore should only be used when benefit and risks are considered together with patients and their relatives. It is important to avoid acute or renewed psychiatric decompensation. We present the current differentiated knowledge for therapy of opioid dependent patients with antipsychotics, antidepressants (e.g. higher fetal risk in case of treatment with fluoxetine and paroxetine) or mood stabilizers. All of them should only be used after considering benefit and risks. During pregnancy, there should not be switched between different antidepressant drugs. Referring mood stabilizers, the intake of valproic acid should be avoided in pregnancy or at least, dosage should be kept as low as possible since severe teratogenetic effects are known. In addition the specific drug treatment of HIV and hepatitis B during pregnancy is described. During childbirth HIV-infected patients should receive zidovudine intravenously to prevent vertical transmission. Co-infection with hepatitis C cannot be treated during pregnancy, since interferons are associated with a severe risk of fetal malformations and ribavirin has teratogenic effects; for this reason interferon therapy should be started after delivery.

RESUMO

The aim of this naturalistic observational study was to investigate EEG alterations in patients under olanzapine treatment with a special regard to olanzapine dose and plasma concentration. Twenty-two in-patients of a psychiatric university ward with the monodiagnosis of paranoid schizophrenia (ICD-10: F20.0), who received a monotherapy of olanzapine were included in this study. All patients had a normal alpha-EEG before drug therapy, and did not suffer from brain-organic dysfunctions, as verified by clinical examination and cMRI scans. EEG and olanzapine plasma levels were determined under steady-state conditions (between 18 and 22 days after begin of treatment). In 9 patients (40.9%), pathological EEG changes (one with spike-waves) consecutive to olanzapine treatment were observed. The dose of olanzapine was significantly higher in patients with changes of the EEG than in patients without changes (24.4 mg/day (SD: 8.1) vs. 12.7 mg/day (SD: 4.8); T = -4.3, df = 21, P < 0.001). In patients with EEG changes, the blood plasma concentration of olanzapine (45.6 µg/l (SD: 30.9) vs. 26.3 µg/l (SD: 21.6) tended to be also higher. The sensitivity of olanzapine dosage to predict EEG changes was 66.7%, the specificity 100% (Youden-index: 0.67). EEG abnormalities during olanzapine treatment are common. These are significantly dose dependent. Thus, EEG control recordings should be mandatory during olanzapine treatment with special emphasis on dosages exceeding 20 mg per day, although keeping in mind that EEGs have only a limited predictive power regarding future epileptic seizures.

RESUMO

Non-invasive screening parameters proving alcohol intoxication are necessary especially in forensic contexts. Results obtained by common measurement methods like the ethanol breath analyzer may be falsified by several parameters like hypoventilation. Therefore, we undertook a pilot study investigating the usefulness and applicability of methanol levels measured in saliva. Our results show that methanol levels in saliva are closely linked to ethanol levels in saliva (r = 0.971, P < 0.0001, t = 5.622, P = 0.000) as well as to ethanol levels in serum (r = 0.786, P = 0.001, t = -1.106, P = 0.058). Therefore, methanol levels measured in saliva might be applicable in order to increase the validity of other non-invasive measurement methods like the ethanol breath analyzer.

RESUMO

AIMS: The individual extent of structural brain tissue changes in patients with alcohol dependence is influenced by genetic factors, gender, age and possibly a dose/duration-effect. Aim of the present study was to investigate different types of alcoholic beverages with regard to hippocampal volume loss in patients suffering from alcoholism. METHODS: We included 52 patients with alcohol dependence and divided them according to their preferred type of beverage consumption (beer, wine, and spirits). Hippocampal volumes were determined using volumetric high-resolution MR imaging. RESULTS: There was a significant difference in hippocampal volumes between patients consuming different beverages (ANOVA: F = 7.454; df = 2; P = 0.0015) with the smallest volumes in the wine group, followed by the spirits group. Furthermore, patients with a preferred spirits consumption showed significantly higher plasma homocysteine levels (ANOVA: F = 3.39; df = 2; P = 0.042). Linear regression analyses revealed an association of homocysteine and hippocampal volume only in the group of patients preferring spirits (R(2) = 0.364; P = 0.008). CONCLUSIONS: Homocysteine-mediated excitotoxicity may be an important pathophysiological mechanism in ethanol-related brain damage, particularly in patients consuming wine and spirits. The extent of brain atrophy in beer consuming patients seems to be more moderate.

RESUMO

OBJECTIVE: Second-generation antipsychotics (SGAs) have proven superior to first-generation antipsychotics regarding relapse prevention, mainly in multiple-episode patients. Practice guidelines recommend SGAs as first-line treatment particularly in first-episode patients, although evidence for this group is still limited. Accordingly, the hypothesis of whether 1-year relapse rate in first-episode schizophrenia under maintenance treatment with risperidone is lower compared to haloperidol in low dose was tested. METHOD: Between November 2000 and May 2004, 1372 patients had been screened for eligibility in the inpatient facilities of 13 German psychiatric university hospitals. 159 remitted patients were enrolled after treatment of an acute first episode of schizophrenia according to ICD-10 F20 criteria. In the randomized controlled trial, double-blind antipsychotic treatment with risperidone or haloperidol was maintained in a targeted dose of 2 to 4 mg/day for 1 year. 151 patients were eligible for analysis. For 127 patients, this was a continuation trial after 8 weeks of randomized, double-blind, acute treatment with the same drugs; 24 patients were additionally randomly assigned after open acute treatment. RESULTS: With both antipsychotics (risperidone, N = 77; haloperidol, N = 74), no relapse evolved. Additionally, according to 2 post hoc defined measures of "marked clinical deterioration," significant differences occurred neither in the 2 respective deterioration rates (risperidone = 9%/23%; haloperidol = 8%/22%) nor in time until deterioration. Both antipsychotics were equally effective regarding significant symptom reduction and improvement in quality of life. Extrapyramidal symptoms were slightly higher with haloperidol. The overall dropout rate of 68%, however, was not significantly different between the 2 drug groups. CONCLUSION: Against the background of an overall favorable outcome, the hypothesized difference between risperidone and low-dose haloperidol regarding relapse prevention could not be supported for this sample of patients with first-episode schizophrenia. Possible design-related reasons for this finding are discussed. With regard to the high dropout rate, special programs are needed to keep schizophrenia patients who are in their early acute and postacute illness course in effective and safe treatment.

RESUMO

PURPOSE: Higher homocysteine levels were found in actively drinking patients with alcohol dependence. Recent studies have shown that high homocysteine levels are associated with alcohol-withdrawal seizures. The aim of the present study was to calculate the best predictive cutoff value of plasma homocysteine levels in actively drinking alcoholics (n = 88) with first-onset alcohol-withdrawal seizures. METHODS: The present study included 88 alcohol-dependent patients of whom 18 patients had a first-onset withdrawal seizure. All patients were active drinkers and had an established diagnosis of alcohol dependence, according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Sensitivity and specificity were calculated by using every homocysteine plasma level found in the study population as cut-off value. A Bayes theorem was used to calculate positive (PPV) and negative (NPV) predictive values for all cutoff values used. RESULTS: The highest combined sensitivity and specificity was reached at a homocysteine plasma cutoff value of 23.9 microM. Positive predictive values ranged from 0.23 to 0.745; the maximum was reached at a homocysteine plasma level of 41.7 microM. Negative predictive values ranged from 0.50 to 0.935, with a maximum at a homocysteine plasma level of 15.8 microM. CONCLUSIONS: Homocysteine levels above this cutoff value on admission are a useful screening tool to identify actively drinking patients at higher risk of alcohol-withdrawal seizures. This pilot study gives further hints that biologic markers may be helpful to predict patients at risk for first-onset alcohol-withdrawal seizures.

RESUMO

Previous research has confirmed stable explicit memory deficits in schizophrenia across disease states. However, little is known about the implicit learning capabilities of individuals with schizophrenia across the course of illness. The current study assessed procedural learning in 19 schizophrenia subjects (DSM-IV criteria) and 19 matched controls using the Serial Reaction-Time Task (SRTT). The severity of negative, positive and disorganized symptoms was assessed using the Scales for the Assessment of Positive and Negative Symptoms. A sub-sample of 11 schizophrenia subjects and 11 controls was reassessed 20 months later when symptoms in the schizophrenia subjects had largely remitted. Schizophrenia subjects were severely impaired on sequence-specific procedural learning during an acute episode. This deficit could not be explained by a general memory or processing speed impairment. Impaired implicit learning scores were significantly related to higher ratings of disorganized symptoms. However, 20 months later, when acute symptoms had remitted, the performance of the schizophrenia subjects on procedural learning had normalized. Our findings might share a conceptual overlap with previous reports of a reduced ability of schizophrenia subjects during an acute episode to adapt ongoing perceptual and behavioral programs to previously experienced regularities in their environment.

RESUMO

OBJECTIVE: Efficacy of atypical antipsychotic in acute schizophrenic episodes is still in debate. This study evaluated treatment practices over 7 years of initial treatment with oral risperidone in acutely exacerbated patients with schizophrenia and in a subgroup of highly agitated, tense, and aggressive patients. Additionally, the study investigated the efficacy and tolerability of risperidone in routine clinical practice. METHODS: In a prospective, multicenter, observational trial from 1996 to 2002, patients with schizophrenia experiencing acute symptom exacerbations were treated with risperidone within 24 hours of inpatient admission. Patients with a total score of > or =15 points on the agitation subscale of the Positive and Negative Syndrome Scale (PANSS) were defined as highly agitated. Efficacy measures were carried out with a modified PANSS, the Clinical Global Impression (CGI) and the Brief Psychiatric Rating Scale (BPRS). RESULTS: A total of 1625 patients were evaluated. Despite prescription of decreasing risperidone dosages over 7 years, efficacy was maintained and tolerability improved significantly. Significant symptom relief occurred in all patients and was more pronounced in the subgroup of highly agitated patients (n = 256; P < 0.001 for PANSS, BPRS, and CGI). At Week 6, the mean daily dosage of risperidone was 4.8 mg in the highly agitated patients and 4.7 mg in the remaining patients, and more than 55% of all patients were receiving risperidone as monotherapy. CONCLUSIONS: Prescribing patterns with risperidone in patients with acutely exacerbated schizophrenia, including highly agitated patients, changed with the experience gained with this compound. In routine clinical practice in this indication, risperidone was found to be effective and well tolerated.
