[The activity of erythrocyte and platelet glutathione reductase and glutathione-S-transferase in paranoid schizophrenia]. / Aktivnost' éritrotsitarnykh i trombotsitarnykh glutationreduktazy i glutation-S-transferazy pri paranoidnoi shizofrenii.

AIM: A comparative evaluation of glutathione reductase (GR) and glutathione-S-transferase (GST) activities in erythrocytes and platelets of patients with schizophrenia. MATERIAL AND METHODS: Fifty patients, 47 men and 3 women, aged 25-56 years (medium 34) with acute paranoid schizophrenia (F20.0 ICD-10) with hallucinatory-paranoid or paranoid syndrome were studied. The control group consisted of 48 healthy people, 45 men and 3 women, aged 21-59 years (medium 38). GR activity was determined by the oxidation of NADP-H in the reduction reaction of oxidized glutathione. GST activity was determined by the rate of chromogenic conjugate formation between glutathione and 1-chloro-2.4-dinitrobenzene. RESULTS: No differences in the erythrocyte GR and GST activities between the control group and patients with schizophrenia were found. The platelet activity of GR and GST was significantly lower in patients compared to the control group (Mann-Whitney U test, p<0.01). Spearman rank correlation analysis showed that the erythrocyte GST activity was significantly correlated with PANSSneg scores when measured at the beginning of the study, GST was higher in those patients who had less PANSSneg scores after treatment (R=-0.41, p<0.05). The activity of platelet GST in patients with schizophrenia was correlated with the severity of positive symptoms (PANSSpos score) at the beginning of the study before taking therapy (R=-0.31, p<0.05), i.e. the more prominent psychotic symptoms were expressed in patients with lower GST activity. Upon completion of therapy, this association disappeared. CONCLUSION: The activity of glutathione-dependent enzymes in the blood cells of schizophrenic patients determined before the beginning of antipsychotic pharmacotherapy may be important for objective assessment of this metabolic system status and the degree of its impairment in patients.

Oral Isotretinoin for the treatment of Aripiprazol-induced acneiform rash.

Acneiform rash is a commonly reported side effect to certain types of medications, including antipsychotic agents. Its clinical presentation consists mainly of papulopustular lesions. Other types of lesions, such as nodular or cystic, can also be observed. Body distribution of the lesions follows a similar pattern to acne vulgaris. Depending on the severity of the case, drug-induced acne may be treated in different ways. In mild cases, the use of topical antibiotics and retinoids in combination is usually effective. With more severe forms, it may be necessary to add oral antibiotics, such as tetracyclines, but a good response is not always achieved. Identification of the drug responsible for the side-effect is mandatory in refractory eruptions. Herein, we present the case of an Aripiprazole-induced acneiform rash successfully treated with oral Isotretinoin. The treatment was effective and well tolerated and there was no need to discontinue the psychopharmacological medication. This is the first study to report this modality of treatment.

[Side Effects of Smoking Cessation]. / Rauchstopp mit Nebenwirkungen.

Side Effects of Smoking Cessation Abstract. We present the case of a clozapine intoxication associated with aspiration pneumonia due to smoking cessation. Clozapine is mainly metabolized by CYP1A2. CYP1A2 is induced by cigarette smoking, which may change the plasma level of clozapine, especially if consuming habits change.

Cognitive deficit in patients with paranoid schizophrenia: Its clinical and laboratory correlates.

The aim of this study was to search for correlates of cognitive impairment in patients with paranoid schizophrenia among clinical, demographic, anamnestic and biochemical markers (NSE, S100B protein, BDNF, hs-CRP). Patients with paranoid schizophrenia (n=125) were examined using the Brief Assessment of Cognitive Function in Schizophrenia, the Rey-Osterrieth Complex Figure task, and a number of clinical scales including the Positive and Negative Syndrome Scale. The majority of patients demonstrated cognitive impairment. The type of impairment was highly heterogeneous and individual. Relationships were found between the degree of executive functioning and family history of mental illness; working memory and age of onset of schizophrenia; and visual memory and psychopathological symptomatology. Negative and affective symptoms were not significantly associated with cognitive functioning. Treatment with first generation antipsychotics was associated with a more frequent impairment of motor skills, and concomitant anticholinergic drugs, with reduced accuracy. Use of second-generation antipsychotics only was associated with better accuracy, working memory and speech fluency. Among the patients, 21.4% had signs of a systemic inflammatory response, indicating a possible role of inflammatory response in the development of schizophrenia. CRP, S100B and NSE levels reflected features of the course of illness and therapeutic response. Patients with lower concentrations of BDNF were characterized by lower processing speeds.

Neuroleptic malignant syndrome with thyroid disorder: An unusual case report.

RATIONALE: Neuroleptic malignant syndrome (NMS) is a life threatening neurologic emergency associated with neuroleptic or antipsychotic agent use. NMS is rarely related to thyroid disease. PATIENT CONCERNS: We report a case of NMS in a 66-year-old male with past medical history of paranoid schizophrenia on chlorpromazine, diabetes, hypertension and asthma, who presented with a humeral fracture after a fall. Patient developed hyperpyrexia, altered consciousness, autonomic instability, elevated serum creatine kinase (CK) without rigidity. DIAGNOSES: CT head and workup for infection were negative. Electroencephalogram (EEG) showed generalized slow wave activity. Ultrasound revealed a large goiter with nodules. INTERVENTIONS: Chlorpromazine was stopped due to concern of NMS. Patient was treated with cooling, fluid and electrolyte maintenance. OUTCOMES: Patient slowly improved and CK level normalized. Thyroid-stimulating hormone (TSH) level trended down from 10.2 mIU/L to 0.02 mIU/L. Patient was discharged with aripiprazole. LESSONS: Hypothyroidism predisposes patients to NMS by altering central dopaminergic systems. The typical symptoms may be masked by hypothyroidism. Thyroid dysfunction should be excluded in all patients with NMS. Discontinuing antipsychotic agents decreases TSH levels which maybe due to the negative feedback of dopaminergic activity. This is the first case report describing dramatic changes in TSH after discontinuing chlorpromazine in NMS.

Rocuronium-sugammadex for electroconvulsive therapy management in neuroleptic malignant syndrome: A case report. / Rocuronio-sugammadex para el manejo de la terapia electroconvulsiva en el síndrome neuroléptico maligno, a propósito de un caso.

Neuroleptics are a group of drugs widely used in the treatment of psychotic symptoms. Among their adverse effects is the ability to trigger a neuroleptic malignant syndrome (NMS). The diagnosis of NMS is determined by exclusion, and its initial therapeutic management should be the withdrawal of neuroleptics, the administration of benzodiazepines, and electroconvulsive therapy (ECT). ECT is an effective treatment in these patients, and in those cases with a poor response to treatment with antipsychotic drugs. A review is presented on the treatment options and anaesthetic implications of ECT used to handle a patient diagnosed with paranoid schizophrenia in the context of NMS.

Clozapine-induced acute interstitial nephritis.

Acute interstitial nephritis is a common cause of acute kidney injury. Acute interstitial nephritis is most commonly induced by drug although the cause may also be infective, autoimmune, or idiopathic. Although eosinophilia and eosinophiluria may help identify this disease entity, the gold standard for diagnosis remains renal biopsy. Prompt diagnosis is important because discontinuation of the culprit drugs can reduce further kidney injury. We present a patient with an underlying psychiatric disorder who was subsequently diagnosed with clozapine-induced acute interstitial nephritis. Monitoring of renal function during clozapine therapy is recommended for early recognition of this rare side-effect.

Weight Gain While Switching from Polypharmacy to Ziprasidone: A Case Report.

Second-generation antipsychotics (SGAs), valproate, and sulpiride are related to significant weight gain and risk of metabolic syndrome (MetS). Among SGAs, olanzapine and clozapine are associated with the highest metabolic risk while ziprasidone is among one of the SGAs with the lowest risk. Several reports suggest that weight loss is observed in switching other antipsychotics to ziprasidone. Here we describe a female patient with chronic paranoid schizophrenia who had an unexpected weight gain and developed MetS during a cross-switch from a polypharmacy of olanzapine, valproate and sulpiride to ziprasidone monotherapy.
