Kandinsky-Clerambault's Syndrome: concept of use for Western psychiatry.

The aim of our paper is to describe Kandinsky-Clerambault's Syndrome, which has important cultural-historical value in the history of psychiatry, and to illustrate the syndrome by means of a case report. Although its component symptoms are known among Western psychiatrists, the syndrome's specific name is generally unknown. The authors suggest that detailed clinical descriptions of some specific conditions may contribute to a more detailed knowledge of psychopathology, a more colorful and memorable view of conditions, with an increased awareness of the historical and cultural origins of psychiatry.

[Vitamin B6 add-on therapy in treatment of schizophrenic patients with psychotic symptoms and movement disorders].

INTRODUCTION: Although there is great progress in the treatment of positive symptoms in schizophrenic patients and movement disorders induced by neuroleptics, it is still a problem for clinicians. In this study vitamin B6 treatment was provided to 15 patients who suffered from schizophrenia and schizoaffective disorder with positive psychotic symptoms and tardive dyskinesia. METHODS: This study was a double-blind crossover controlled during 9 weeks. Each patient was treated with up to 400 mg/day vitamin B6 versus placebo. Every week the patients' conditions were evaluated with Positive and Negative Symptoms Scale (PANSS), Extrapyramidal Symptoms Rating Scale (ESRS) and a blood sample of level pyridoxal was taken. RESULTS: The results did not show any therapeutic effect of psychotic symptoms from vitamin B6 added to antipsychotic agents, which patients received on a constant base. On the other hand, there was significant improvement in tardive dyskinesia and parkinsonian symptoms. There was no direct correlation between pathological symptoms and the serum baseline level of vitamin B6 nor its level during the treatment. CONCLUSION: The authors suggest that vitamin B6 may be efficient as the treatment for tardive dyskinesia and parkinsonism induced by neuroleptic agents. There is a need for further studies with larger samples and higher doses of vitamin B6 in order to examine the possibility of a positive therapeutic effect as an augmentation agent for the treatment of psychotic symptoms.

Acute dementia with delirium due to vitamin B12 deficiency: a case report.

OBJECTIVE: Vitamin B12 (cobalamin) is a key component in the catabolism of monoamines. B12 deficiency is associated with various neuropsychiatric disorders and may be more frequent in psychiatric inpatients. The authors describe a case report of a newly admitted and relatively young patient (52 years old) with organic psychosis secondary to vitamin B12 deficiency. No other overt clinical features of cobalamin deficit were observed. Symptoms were resolved with B12 and folate replacement. The patient's mental status remained stable over the 3 months after the treatment. The authors note that organic mental changes were reversible with B12 replacement. CONCLUSIONS: The authors propose that determination of serum vitamin B12 and folic acid levels should be recommended as routine screening in all new admissions of psychiatric patients regardless of their age or previous state of health.

Lithium-induced tremor treated with vitamin B6: a preliminary case series.

OBJECTIVE: The occurrence of tremor in patients receiving lithium is well known, but the management of this side effect is a significant problem both for patients and physicians. Although some reports have suggested that beta-blockers may be useful in treating lithium-induced tremor (LT), these agents have different side effects which limit the possibility of their use. Vitamin B6 has been reported to be effective in treatment of patients suffering from different kinds of neuroleptic-induced movement disorders including parkinsonism and tardive dyskinesia. METHODS: This report presents the results of a preliminary four-week open-label clinical trial of five patients who suffered from LT and who were treated with vitamin B6 (900-1200 mg/d). The severity of tremor was assessed using the tremor subscale from the Simpson-Angus Scale (SAS) and Subjective Clinical Improvement Impression scale (SCII). RESULTS: After the addition of vitamin B6 to their treatment, according to the SAS scores four patients showed an impressive improvement until total disappearance of tremor. The subjective scale, on which the patients' scored their impression of clinical improvement, showed similar results. None of the patients suffered from any side effects attributable to vitamin B6. CONCLUSIONS: The results suggest that vitamin B6 may alleviate LT, double-blind controlled trials are needed to establish this effect.

Vitamin B6 as add-on treatment in chronic schizophrenic and schizoaffective patients: a double-blind, placebo-controlled study.

BACKGROUND: Vitamin B6, or pyridoxine, plays an intrinsic role in the synthesis of certain neurotransmitters that take part in development of psychotic states. Several reports indicate that vitamin B6 may be a factor in a number of psychiatric disorders and related conditions, such as autism, Alzheimer's disease, hyperactivity, learning disability, anxiety disorder, and depression. Moreover, there are anecdotal reports of a reduction in psychotic symptoms after vitamin B6 supplementation of psychopharmacologic treatment of patients suffering from schizophrenia or organic mental disorder. The aim of this study was to examine whether vitamin B6 therapy influences psychotic symptoms in patients suffering from schizophrenia and schizoaffective disorder. METHOD: The effects of the supplementation of vitamin B6 to antipsychotic treatment on positive and negative symptoms in 15 schizophrenic and schizoaffective patients (DSM-IV criteria) were examined in a double-blind, placebo-controlled, crossover study spanning 9 weeks. All patients had stable psychopathology for at least 1 month before entry into the study and were maintained on treatment with their prestudy psychoactive and antiparkinsonian medications throughout the study. All patients were assessed using the Positive and Negative Syndrome Scale (PANSS) for schizophrenia on a weekly basis. Patients randomly received placebo or vitamin B6, starting at 100 mg/day in the first week and increasing to 400 mg/day in the fourth week by 100-mg increments each week. RESULTS: PANSS scores revealed no differences between vitamin B6- and placebo-treated patients in amelioration of their mental state. CONCLUSION: Further studies with larger populations and shorter duration of illness are needed to clarify the question of the possible efficacy of vitamin B6 in treatment of psychotic symptoms in schizophrenia.

Successful use of donepezil for the treatment of psychotic symptoms in patients with Parkinson's disease.

The risk of psychosis among patients with Parkinson's disease (PD) is high, and the management of these patients remains a substantial problem for physicians. Atypical antipsychotics, despite their advantages over conventional antipsychotics, can cause different side effects and deterioration of PD. Several reports have suggested that donepezil can be helpful in the treatment of psychotic conditions in patients with dementia with Lewy bodies and Alzheimer's disease. This report presents the results of preliminary study of six patients (four women, two men; age range, 60-75 years) with PD (range of duration, 3-7 years) and dementia complicated by psychosis. All patients were treated with antiparkinsonian therapy, and donepezil was added to their regular treatment. The severity of the psychotic symptoms was assessed using the Scale for the Assessment of Positive Symptoms, and extrapyramidal symptoms were assessed using the Simpson-Angus Scale. With the addition of donepezil (as much as 10 mg/day) to their constant antiparkinsonian treatment, five patients had clinically significant (more than 53%) improvement on the assessment scale, and one patient had minimal (24%) improvement after 6 weeks of the treatment. None of the patients had side effects or deterioration of parkinsonian symptoms. The results suggest that donepezil may ameliorate psychotic symptoms in patients with PD, but this will need to be tested further in controlled, double-blind trials.

High-dose olanzapine for treatment-refractory schizophrenia.

To date there is no common or adequate therapeutic strategy for treatment of refractory schizophrenic patients. Increasing antipsychotics' doses in treatment-resistant schizophrenic patients is the most common intervention used by clinicians. Olanzapine is an atypical antipsychotic, which in a number of double-blind, placebo-controlled studies has been found to be more effective than haloperidol for the treatment of positive and negative symptoms of schizophrenia. During the last few years there have been several reports of successful results in prescribing olanzapine at dosages of more than 25 mg/day for treatment-resistant schizophrenic and schizoaffective patients. This report presents the results from the treatment of three resistant schizophrenic patients treated successfully with high dosages of olanzapine (35, 40, and 60 mg/day). None of the patients had any side effects, including abnormal laboratory levels and weight gain. The results and literature data suggest that in clinical practice some schizophrenic patients resistant to conventional neuroleptic treatment and not responding to olanzapine at recommended dosages as high as 20 mg/day may respond to higher dosages such as 40 or 60 mg/day, and these dosages are well tolerated. Further prospective clinical studies are needed.

Donepezil as add-on treatment of psychotic symptoms in patients with dementia of the Alzheimer's type.

Traditionally, the neuropsychiatric symptoms of Alzheimer's disease (AD) have been managed with neuroleptics or benzodiazepines, which have serious side effects. Preliminary observations suggest the possible value of cholinesterase inhibitors in the amelioration of psychotic symptoms in patients with dementia of the Alzheimer's type, dementia with Lewy bodies, and in patients with Parkinson's disease. Twelve inpatients with AD with psychotic symptoms and lack of improvement of their delusions/hallucinations during perphenazine treatment (8 mg/day) for 3 weeks received random open-label donepezil 5 mg daily in addition to an ongoing treatment of 8 mg/day perphenazine or 16 mg/day perphenazine. Assessments conducted at baseline and after weeks 2 and 4 included the Mini-Mental State Examination, the Global Deterioration Scale, the Positive and Negative Symptoms Scale, and the Clinical Global Impressions scale. Frequency of extrapyramidal symptoms was measured according to the Abnormal Involuntary Movement Scale. The donepezil-perphenazine group exhibited substantially greater and clinical improvements in mental state. At the end of the trial (4 weeks), Positive and Negative Symptoms Scale scores revealed significant differences between both groups (p = 0.006). The Clinical Global Impressions scale and the Mini-Mental State Examination scores also showed significant differences between the donepezil-perphenazine group and the perphenazine group (p = 0.028 and p = 0.027 respectively). No significant differences were found in the Global Deterioration Scale scores. Abnormal Involuntary Movement Scale scores showed a significant deterioration in extrapyramidal symptoms in the perphenazine group compared with the donepezil-perphenazine group (p = 0.016). Donepezil augmentation of neuroleptics may be appropriate for those patients for whom neuroleptic monotherapy either does not lead to symptom remission or is associated with intolerable adverse effects. This was an open-label study and there is need for larger studies with double-blind control and a long-term study design to define the efficacy of donepezil for patients with AD and psychotic symptoms.

Vitamin B6 versus mianserin and placebo in acute neuroleptic-induced akathisia: a randomized, double-blind, controlled study.

Treatment strategies against acute neuroleptic-induced akathisia (NIA) include anticholinergic (antimuscarinic) agents, dopamine agonists, GABAergic agents, beta-blockers, benzodiazepines, and serotonin antagonists. However, many patients who have acute akathisia fail to respond. In previous studies, mianserin and vitamin B6 were found to be effective in the treatment of acute akathisia. The purpose of this study was to compare the efficacy of B(6), mianserin and placebo in the treatment of acute NIA. Sixty schizophrenia and schizoaffective inpatients who have NIA were randomly divided to receive vitamin B(6) 1,200 mg/d, mianserin 15 mg/d, or placebo for 5 days, in a double-blind design. The Barnes Akathisia Rating Scale, Brief Psychiatric Rating Scale, and Clinical Global Impression were used to assess the severity of NIA and psychotic symptoms. The assessment was made at baseline and daily for the duration of the study. Compared with the placebo group, the vitamin B(6)-treated and mianserin-treated patients showed a significant improvement in the subjective (P < 0.0001), subjective distress (P < 0.0001), and global (P < 0.0001) subscales. The objective subscale did not show significant positive results (P = 0.056), but there was a trend toward symptom amelioration in both groups. A reduction of at least 2 points on the Barnes Akathisia Rating Scale global subscale was noted in the vitamin B(6) group (13/23, 56%) as well as in the mianserin groups (13/20, 65%), and in only one patient in the placebo group (1/17, 6%; P < 0.0005). Our results indicate that high doses of B(6) and a low dose of mianserin may be a useful addition to current treatments of NIA. The efficacy of vitamin B(6) and mianserin suggests that the pathophysiology of acute NIA is heterogeneous with the various subtypes of acute NIA responding differently to the various pharmacological approaches.

Augmentation with amisulpride for schizophrenic patients nonresponsive to antipsychotic monotherapy.

Despite the effectiveness of antipsychotic medications in treatment of schizophrenia, about 30% of patients who receive an adequate treatment have significant persisting symptoms. The problem of treatment-resistant psychosis is an important and difficult one. The aim of this study was to retrospectively evaluate the efficacy and safety of amisulpride augmentation in treatment-resistant schizophrenic patients. To the best of our knowledge, this is the first report about resistant schizophrenic and schizoaffective patients treated with the combinations of risperidone and amisulpride and ziprasidone and amisulpride. Data were collected from patient records. A total of 15 resistant schizophrenic patients (7 men, 8 women, 54.0 +/- 16.9 years old) were included in the study. Before addition of amisulpride, the patients were treated with monotherapy by atypical neuroleptics (clozapine, olanzapine, risperidone, or ziprasidone). The mean amisulpride dose was 693.3 +/- 279.6 mg/d. The mental state of 12 (80%) patients treated with combination was improved. Three (20%) patients showed no change in their mental state. Only 2 patients treated with a combination of risperidone and amisulpride had mild side effects. The results are preliminary and require confirmation in a randomized controlled trial. The authors suggest that amisulpride may be a promising option as an augmentation strategy in treatment-resistant schizophrenic patients.

Quetiapine-associated depression in a patient with schizophrenia.

Depression has been reported as a side effect of a wide variety of drugs in clinical medicine. Neuroleptics may cause depression in persons with or without any past history of psychiatric illness. Clinically, these drug-induced depressions may go unnoticed and thus create therapeutic problems. The authors present a case of quetiapine-associated depression in a patient being treated for schizophrenia. To the best of our knowledge it is the first description of depression associated with quetiapine treatment. This case report suggests that atypical antipsychotics may be a cause of depression. This is noteworthy because these medications have been found in the past to have an antidepressant action. Further data based on controlled studies are needed.

Lithium intoxication associated with intramuscular ziprasidone in schizoaffective patients.

Antipsychotic agents have been used for the treatment of mood disorders in schizophrenic and schizoaffective patients. It has also been suggested that combinations of lithium and antipsychotics may be more effective than either class alone in treatment of schizoaffective patients. Lithium is known to interact with a variety of medications, including conventional and atypical antipsychotics. Although these combinations are generally well tolerated, they may sometimes lead to various adverse side effects. The authors report two schizoaffective patients with manic psychotic state and psychomotor agitation treated with lithium. Both patients developed symptoms of lithium intoxication after intramuscular ziprasidone treatment. To the best of their knowledge, this is the first description of such an adverse effect of this new atypical neuroleptic drug. They assume that lithium intoxication in the two presented cases was associated with the fast increase of ziprasidone serum level after its parenteral application, possibly affecting lithium excretion and thereby leading to lithium intoxication.
