[Trazodone Contramid® in clinical practice: personalizing antidepressant intervention].

Aim: This paper examines the use of Trazodone Contramid® in major depressive disorder (MDD), with a focus on practical guidance regarding real world challenges. The paper includes clinical case reports, developed for didactic reasons, which detail the practical management with Trazodone Contramid® of patients with MDD and either insomnia or anxiety or dementia or isolated (ipo)manic symptoms, which often fulfill the criteria for a diagnosis of MDD with with anxious distress or MDD with mixed features, according to the new DSM-5 classification.

Methods: A literature search was performed using appropriate keywords to identify studies where any formulation of trazodone was used.

Decreased plasma endogenous soluble RAGE, and enhanced adipokine secretion, oxidative stress and platelet/coagulative activation identify non-alcoholic fatty liver disease among patients with familial combined hyperlipidemia and/or metabolic syndrome.

Objective: In patients with familial combined hyperlipidemia (FCHL), without metabolic syndrome (MS), occurrence of non-alcoholic fatty liver disease (NAFLD) is related to a specific pro-inflammatory profile, influenced by genetic traits, involved in oxidative stress and adipokine secretion. Among FCHL or MS patients, hyperactivity of the ligand-receptor for advanced glycation-end-products (RAGE) pathway, as reflected by inadequate protective response by the endogenous secretory (es)RAGE, in concert with genetic predisposition, may identify those with NAFLD even before and regardless of MS.

Methods: We cross-sectionally compared 60 patients with vs.

Variations of plasma leptin and adiponectin levels in autistic patients.

Autism is a neurodevelopmental disorder with pathogenesis not completely understood. Although a genetic origin has been recognized, it has been hypothesized a role for environmental factors, immune dysfunctions, and alterations of neurotransmitter systems. In young autistic patients we investigated plasma leptin and adiponectin levels over a year period.

Effects of spa therapy on serum leptin and adiponectin levels in patients with knee osteoarthritis.

Adipocytokine, including leptin and adiponectin, may play an important role in the pathophysiology of osteoarthritis (OA). Spa therapy is one of the most commonly used non-pharmacological approaches for OA, but its mechanisms of action are not completely known. The aim of the present study was to assess whether spa therapy modified plasma levels of leptin and adiponectin in thirty patients with knee OA treated with a cycle of a combination of daily locally applied mud-packs and bicarbonate-sulphate mineral bath water.

Plasma levels of asymmetric dimethylarginine in cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy.

Background: Asymmetric dimethylarginine (ADMA) is a marker of endothelial dysfunction and a new independent risk factor for adverse cerebrovascular events in small vessel disease. Conversely, L-arginine (LARG) may have a protective role.

Methods: To assess ADMA, LARG levels and LARG/ADMA ratio in 16 patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) and normal controls, and to look for possible correlations with white matter changes.

Topiramate effects on plasma serotonin levels in children with epilepsy.

Topiramate (TPM) is a new, effective and safe antiepileptic drug. TPM is also effective in treating a wide spectrum of conditions such as eating disorders and related anomalies, bulimia nervosa and other conditions in which serotonin (5-hydroxytryptamine, 5-HT) is involved pathogenetically. Plasma serotonin mainly derives from blood platelets, which represent a valid model of serotoninergic neurons.

Sympathetic overactivity and plasma leptin levels in Rett syndrome.

Rett syndrome (RTT) is a severe developmental-neurological disorder, characterized by profound and progressive loss of intellectual functioning, occurring after a period (of at least 6 months) of normal development with classic stereotype hand movements, gait ataxia, jerky truncal ataxia, deceleration of brain and body organ growth and cardiac dysautonomia. Pathogenesis of sympathetic overactivity in RTT is unknown, but a previous study observed increased plasma leptin levels in Rett girls and it is well known the role of leptin in the regulation of sympathetic nervous system activity. Aim of our study is to evaluate a relationship between plasma leptin levels and sympathetic activity in RTT.

Immunological characterization of respiratory syncytial virus N protein epitopes recognized by human cytotoxic T lymphocytes.

Virus-specific cytotoxic T lymphocytes (CTLs) are crucial for the control of respiratory syncytial virus (RSV) infection. This study has identified CTL epitopes of the RSV N protein in healthy subjects. We screened the primary structure of the N protein for HLA-A 0201-binding amino acid consensus motifs, identifying three peptides designated as N-RSV1, N-RSV2, and N-RSV3.

Effect of iloprost on plasma asymmetric dimethylarginine and plasma and platelet serotonin in patients with peripheral arterial occlusive disease.

Background: Iloprost, a prostacyclin analogue, is used in the treatment of peripheral arterial occlusive disease at Leriche-Fontaine stages III-IV, through intravenous infusion for at least 21 days. Recently, iloprost has been shown to be safe and effective in critical limb ischemia patients when administered per 7 days. We investigated in patients at Leriche-Fontaine stages III-IV the effect of 1-week treatment with iloprost on plasma asymmetric dimethylarginine (ADMA), plasma and platelet serotonin, and on clinical response.

Activity of citalopram on adenosine and serotonin circulating levels in depressed patients.

Citalopram is a selective serotonin reuptake inhibitor used in the treatment of depression. Recent investigations have shown that it reduces in rat brain the release of excitatory amino neurotransmitters acid glutamate and aspartate by the involvement of the inhibitory neuromodulator adenosine. In this study, we described citalopram and serotonin levels in plasma and platelets, as well as plasma adenosine levels, in depressive patients during acute and chronic administration of citalopram.

Plasma catecholamine levels after fluoxetine treatment in depressive patients.

It is known that selective serotonin reuptake inhibitors, widely used as antidepressive drugs, act by inhibiting the cell reuptake of serotonin, but their effect on the catecholaminergic system is not yet completely understood. In this study, we investigated plasma concentrations of norepinephrine, epinephrine and dopamine after acute and chronic administration of fluoxetine in depressive patients. Twelve patients affected by major depression received a single oral dose of fluoxetine in the morning, 5 mg in the first 5 days, 10 mg from the 6th to the 10th day and 20 mg from the 11th to the 40th day.

Can serotonin and fluoxetine levels in plasma and platelets predict clinical response in depression?

We describe the clinical response and the area under the concentration-time curve (AUC) of fluoxetine and serotonin levels in plasma and platelets in 10 depressive patients treated with 20 mg/day of fluoxetine for 30 days. Depression severity was assessed at baseline and after treatment by the Hamilton Rating Scale for Depression (HAM-D). "Good clinical response" was defined as a decrease of 50% or more of the total HAM-D score compared with baseline.

Nimodipine: drug pharmacokinetics and plasma adenosine levels in patients affected by cerebral ischemia.

Background And Objective: Nimodipine is a dihydropyridine calcium channel blocker used in the treatment of ischemic damage in subarachnoid hemorrhage. Recent investigations have shown that it is able to inhibit adenosine transport in human red blood cells and parietal cortex neurons. In this study we investigated the pharmacokinetics of nimodipine and the effect on plasma adenosine levels in patients affected by cerebral ischemia.

Serotonin and fluoxetine levels in plasma and platelets after fluoxetine treatment in depressive patients.

Depression is a mood disorder characterized by complex alterations of neurotransmitters such as serotonin, norepinephrine, and dopamine. In particular, there is substantial evidence of abnormalities in serotonin neurotransmission. Peripheral parameters of serotoninergic transmission, such as the 5-hydroxytryptamine content of plasma and platelets, have been used to identify biochemical alterations related to depression.

Increase of adenosine plasma levels after oral trimetazidine: a pharmacological preconditioning?

Trimetazidine (1-[2,3,4-trimethoxybenzyl] piperazine) (TMZ) is a cellular anti-ischemic agent able to prevent intracellular ATP decrease, limit intracellular acidosis, protect against oxygen-free radical-induced toxicity and inhibit neutrophil infiltration. However, its definitive mechanism of action had not been identified. Recent studies showed the existence of an endogenous mechanism of cellular protection against ischemia, defined as 'ischemic preconditioning'.
