SummaryThree adolescent and two adult patients suffering from chronic excited psychoses (either schizophrenia or schizoaffective disorder) resistant to traditional neuroleptics and clozapine were treated with combined clozapine-lithium. Improvement was assessed with the Positive and Negative Symptoms Scale, the Brief Psychiatric Rating Scale and the Clinical Global Impressions, administered before and during combined clozapine-lithium treatment. All patients demonstrated a significant improvement with this combination. There was no occurrence of agranulocytosis, neuroleptic malignant syndrome or other clinically significant adverse effects.

‘Alysis’ )abbreviation of Neuroanalysis(, - is the chosen definition for the rearrangement of psychiatric phenomology to approximate the hypothesized etiology of mental disorders. Currently the relevant scales such as Positive and Negative Symptoms Scale (PANSS) for schizophrenia and the Hamilton scales for depression and anxiety, and Mania Rating Scale have no specific guiding principle in the order of items. ‘Alysis’ is a reorganization of multiple known scales to fit a future brain-related diagnostic approach to mental disorders. Due to the regrouping of items from different scales and reorganizing them according to a brain-related hypothetic order, it is necessary to reassess the reliability of the new ‘Alysis’ rearrangement. In this work the new ‘Alysis’ format is described and then using t-scores analysis, compared to the widely-used Brief Psychiatric Rating Scale (BPRS) scale for mental disorders. It is shown that ‘Alysis’ is reliable thus can be a good diagnostic platform to go ahead and generate personalized testable-predictions about brain-related diagnostics for psychiatric patients.

AbstractObjectiveThe assessment of outcome in schizophrenic patients should consider both the response to treatment and the recovery of social skills. The aim was to evaluate the outcome and related psychostructural and clinical factors in schizophrenic patients after they underwent 6 months of residential multimodal treatment.MethodsFifty-two schizophrenic patients enrolled in a multimodal treatment program were included in the study. Symptomatology and social functioning were assessed with the Brief Psychiatric Rating Scale (BPRS) and the Social and Occupational Functioning Assessment Scale (SOFAS). The Karolinska Psychodynamic Profile (KAPP) was used for the psychostructural evaluation.ResultsAfter 6 months there was a significant improvement in the global scores of BPRS, SOFAS, and some areas of KAPP. The personality (KAPP) and social-occupational functioning (SOFAS) at baseline (T0) correlated with the global score of BPRS at 6 months (T6); moreover, SOFAS at T6 correlated with BPRS and KAPP at T0 and with the illness duration.ConclusionsThe better the personality functioning in schizophrenic patients the better seems to be the response to treatment, with regard to symptoms as well as rehabilitation. Personality assessment might be useful for the individualisation of therapies, even within the context of a standardised program.

Depressive Syndromes

Ninety-five schizophrenic patients were assessed using the Present State Examination, the Brief Psychiatric Rating Scale and the Scale for the Assessment of Negative Symptoms. Negative and depressive symptoms were frequent, and significant relationships among negative symptom complexes and depressive syndromes were noted. Retardation, lack of energy, slowness, and other symptoms of depression were significantly associated with the negative symptoms of schizophrenia. Depressed affect per se did not have a significant correlation with negative symptoms.

Care Costs

Objectives: Schizophrenia is a severe psychiatric disorder that has profound effects on both individuals and the community. Notwithstanding the suggestion for treating schizophrenia with a minimum dose of drugs, antipsychotic polypharmacy increases the patient’s care costs and drug interactions. Aripiprazole reduces the metabolic side effects of antipsychotic polypharmacy treatment. DRD2 and HTR2A can serve as predictors for response to treatment in schizophrenic patients. The purpose of this survey was to measure the DRD2 and HTR2A genes expression in the peripheral blood samples using Real-Time Quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR). Methods: A total of 19 patients with a long history of schizophrenia who received at least two types of antipsychotics with daily doses of more than 500 mg of chlorpromazine were entered into the study. The response rates to the treatment based on scores in the Brief Psychiatric Rating Scale (BPRS) questionnaire and DRD2 and HTR2A expression were compared between antipsychotic polypharmacy status and 6 months after monotherapy with aripiprazole. Results: The levels of DRD2 expression decreased significantly after the intervention. The mean changes in HTR2A expression and the BPRS questionnaire and also the relationship between changes in DRD2 and HTR2A expression and changes in BPRS score after the intervention were not significant. Discussion: The conversion of the antipsychotic polypharmacy state to monotherapy with aripiprazole has been accompanied by a significant decrease in DRD2A expression. These genes can be used for evaluating the response rate of schizophrenia treatments in the future.

Schizophrenic Outpatients

This paper presents an open study which evaluated the clinical effects of a partial and progressive reduction in neuroleptic medication in 32 outpatients suffering from schizophrenia who were receiving high doses (equivalent of ≥ 18 mg of oral haloperidol per day; EHL). After an observation period of twelve weeks, each subject's dose of neuroleptics was reduced by 50% at the rate of 10% every four weeks. Patients were receiving a mean of 62 mg per day EHL at the beginning of the study and 30 mg per day EHL at the completion of the study. After the reduction, the following was observed: 1. a significant but modest change in psychopathology: a decrease in negative symptoms and in the total score on Brief Psychiatric Rating Scale; and 2. a significant increase in tardive dyskinesia symptoms. Six subjects relapsed but five of them recovered without increasing their reduced medication. Results of this study are discussed in the context of trying to find a minimal maintenance dose in the treatment of schizophrenia. The relative paucity of change despite a large reduction in medication argues for réévaluation of dosage in patients on high or very high doses of neuroleptics. The results suggest that many patients taking high doses could be maintained on significantly lower doses of neuroleptics. With gradual reduction of medication it would seem that many patients who are receiving a high dose of neuroleptic can achieve a lower dose than their current maintenance level.

SummaryNimodipine was administered at the daily dose of 90 mg po, for 30 days, to ten chronic undifferentiated schizophrenics, eight men and two women, aged 31-35 years, maintained on previously longlasting neuroleptic treatments. In five patients, a placebo period of 15 days preceded the administration of the drug. Monitoring of psychiatric symptomatology by the Brief Psychiatric Rating Scale (BPRS) revealed significant nimodipine-induced improvement. However, the Andreasen Rating Scale for Positive Symptoms (SAPS) showed favourable effects only in the five patients who had not received placebo, while in the others both SAPS and the Andreasen Rating Scale for Negative Symptoms (SANS) showed no significant effect of therapy. The Tardive Dyskinesia Scale revealed no improvements of neurological symptoms after either placebo or drug treatment. Measurement of plasma MHPG concentrations revealed no significant changes induced by either placebo or nimodipine, while HVA plasma levels showed a trend toward decrease, and prolactin a trend toward increase, after nimodipine.

First Admission

The symptomatic response to standard antipsychotic treatment was assessed over the first 4 weeks of hospitalisation in 39 patients with DSM-III schizophrenia, active phase, using the Brief Psychiatric Rating Scale (BPRS). While highly significant improvement was noted overall, 36% of patients either did not improve or worsened. Furthermore there was no diminution in the withdrawal-retardation factor of the BPRS. Patients experiencing their first admission to hospital, all with recent-onset illness, were then compared with patients who presented with a recurrence and had illness of at least 3 years duration. Despite similarities in overall response, withdrawal-retardation scores did not diminish in recent-onset patients, in contrast to multiple admissions who demonstrated significant improvement. These findings suggest greater responsiveness of negative symptoms to treatment in patients with longstanding illness, and possibly a poorer prognosis in first admission patients with deficit manifestations.
