BACKGROUND: Schizophrenia is a psychiatric disorder characterized by positive and negative symptoms often accompanied by depression and cognitive deficits. Positive symptoms, like delusions and hallucinations are caused by an excess of dopamine (DA) signaling and are treated with the second generation antipsychotic drugs. Negative symptoms of schizophrenia are represented by social withdrawal, apathy and blunted emotional response. It was demonstrated that co-administration of risperidone and selective serotonin reuptake inhibitors alleviated depressive symptoms and cognitive dysfunction in animal models of schizophrenia...

OBJECTIVE: Selective serotonin reuptake inhibitors (SSRIs) remain the first-line treatment for posttraumatic stress disorder (PTSD). However, adjunctive atypical antipsychotics are often used to target residual or refractory symptoms. Asenapine is a novel atypical antipsychotic that possesses a high serotonin (5-HT2A) to dopamine (D2) affinity ratio and alpha-adrenergic antagonism, which may be advantageous in treating PTSD. This pilot study aimed to identify the therapeutic potential of asenapine as an adjunctive treatment for PTSD...

AIM: Sexual dysfunction, common in schizophrenia, may be further exaggerated by antipsychotics, especially those of First Generation (FGAs), and antidepressants, such as Selective Serotonin Reuptake Inhibitors (SSRs). Mirtazapine, an antidepressant characterized by its different action mechanism compared with that of the majority of other antidepressants, may improve SSRI-induced sexual dysfunction in patients with depression. It is unknown, however, whether mirtazapine improves sexual functioning in schizophrenia...

OBJECTIVES: This study aimed to investigate mirtazapine-induced changes in responsive neurostimulator (RNS) recordings in a patient with epilepsy. MATERIALS AND METHODS: Cortical detection/stimulation counts from an RNS implanted in a patient with bitemporal epilepsy were matched to mirtazapine use to see if that drug altered hippocampal excitability. RESULTS: Mirtazapine decreased hippocampal stability; when mirtazapine was held after a washout period, DSC counts declined, but when it was retrialed, DSC counts increased...

An 83-year-old man with chronic renal failure was referred to our hospital because of subacute progressive right hemiparesis. A brain MRI showed high-intensity lesions in bilateral middle cerebellar peduncles and white matter of the left frontal lobe on T2-weighted images. The lesions increased gradually, so we suspected a brain tumor because (1)H-MRS images showed elevated Cho and decreased NAA, and also pathologic findings of the brain biopsy suggested glioblastoma. However, JC virus (JCV) in cerebrospinal fluid was revealed highly positive by PCR...

Weight gain and metabolic abnormalities are extensively found in patients taking psychotropic medications. Although mainly antipsychotics have been implicated, also antidepressants carry the potential to induce weight gain, with tricyclics and mirtazapine being associated with the greatest weight gain. It has been suggested that this could be due to the different ability of antidepressants to block adrenergic, cholinergic, and histaminergic postsynaptic receptors. To date, however, the link between antidepressant-induced weight gain and their receptor affinity profile has not been established...

Paraneoplastic itch occurs as the result of a systemic reaction to an underlying malignancy. Paraneoplastic itch is most commonly associated with lymphoproliferative malignancies and solid tumors that result in cholestasis. Paraneoplastic itch may occur in the absence of a primary rash or in association with dermatologic conditions such as erythroderma, acanthosis nigricans, dermatomyositis, Grover's disease, and eruptive seborrheic keratosis. Treatment of paraneoplastic itch is centered on targeting the underlying malignancy responsible for the systemic reaction...

Pruritus is a bothersome and prevalent symptom reported by patients suffering from both cutaneous and extracutaneous diseases. Psychogenic pruritus, also referred to as functional itch disorder, is a distinct clinical entity. According to the definition proposed by the French Psychodermatology Group (FPDG) in 2007, the disorder is characterized by pruritus which is the chief complaint and psychologic factors that contribute to eliciting, worsening, and sustaining the symptoms. Specific diagnostic criteria were proposed, including 3 compulsory and 7 optional, of which 3 have to be met in order to establish the diagnosis...

Psoriasis is a common chronic inflammatory skin disease observed in about 1-3% of the general population. About 60-90% of patients with psoriasis suffer from itching. Interestingly, in the past itch was not considered as an important symptom of psoriasis. Despite the high frequency of itch in psoriasis, the pathogenesis of this symptom is still not fully elucidated. Although most studies indicate neurogenic inflammation and the role of neuropeptides, other mediators may be important as well. The majority of psoriatic patients consider itch as the most bothersome symptom of the disease as it significantly alters daily functioning and psychosocial well-being...

Ultrasonic-assisted magnetic dispersive solid-phase microextraction coupled with high performance liquid chromatography has been developed for extraction and determination of mirtazapine, N-desmethyl mirtazapine, and 8-hydroxy mirtazapine in human urine and water samples. Magnetic graphene oxide-polyaniline nanocomposite (MGOPA) as a novel SPME sorbent was synthesized and used for the microextraction process. The analytical performance of MGOPA was compared with magnetic graphene oxide nanocomposite and indicated that the new sorbent was quite effective for extraction of mirtazapine, N-desmethyl mirtazapine, and 8-hydroxy mirtazapine...

Cognitive deficits are a core symptom of schizophrenia. It is controversial whether antidepressants could improve cognitive symptoms in schizophrenia patients. The present study was designed to identify the therapeutic effect of antidepressants on cognitive deficits in schizophrenia. In the present study, adolescent rats were repeatedly exposed to dizocilpine, which can induce cognitive deficits associated with schizophrenia. Then these rats were treated by six antidepressants (fluvoxamine, sertraline, paroxetine, escitalopram, venlafaxine, mirtazapine) or vehicle...

Several clinical reports have documented a beneficial effect of the addition of a low dose of risperidone to the ongoing treatment with antidepressants, in particular selective serotonin reuptake inhibitors (SSRI), in the treatment of drug-resistant depression and treatment-resistant anxiety disorders. In the present study, we investigated the effect of treatment with the antidepressant escitalopram (SSRI) given separately or jointly with a low dose of risperidone (an atypical antipsychotic) in the forced swim test and in the elevated plus-maze test in rats...

Newer generation antidepressant drugs (ADs) are widely used as the first line of treatment for major depressive disorders and are considered to be safer than tricyclic agents. In this critical review, we evaluated the literature on adverse events, tolerability and safety of selective serotonin reuptake inhibitors, serotonin noradrenaline reuptake inhibitors, bupropion, mirtazapine, trazodone, agomelatine, vilazodone, levomilnacipran and vortioxetine. Several side effects are transient and may disappear after a few weeks following treatment initiation, but potentially serious adverse events may persist or ensue later...
