The anticonvulsant effect of citalopram as an indirect evidence of serotonergic impairment in human epileptogenesis

AbstractSome evidence would indicate that a serotonergic deficit may be involved in epileptogenesis. A preliminary trial of citalopram, a selective inhibitor of serotonin reuptake, was carried out. Citalopram 20mg/day was given to 11 non-depressed patients with poorly controlled epilepsy as an add on treatment with an open label design for 8–10 months. The median seizure frequency dropped by 55.6% in the whole group, with nine patients improving by at least 50%. No adverse reactions occurred with the exception of mild drowsiness. There were no changes of post-treatment as compared to pre-treatment AED serum concentrations. Although controlled studies are required to confirm the anticonvulsant effect of citalopram, these findings may be regarded as an indirect evidence of serotonergic impairment in human epileptogenesis

Short-term efficacy of ultramicronized palmitoylethanolamide in peripheral neuropathic pain.

Introduction. This study evaluates the efficacy of palmitoylethanolamide ultramicronized (PEA-um) as an add-on treatment in patients with diabetic or traumatic neuropathic pain (NP). Methods. 30 patients with chronic NP were assessed with Visual Analogue Scale (VAS), NP Symptom Inventory (NPSI), and Health Questionnaire Five Dimensions (EQ-5D), both at baseline and after 10 and 40 days of treatment with 1200 mg/die of PEA-um. All other therapies were maintained stable during the follow-up period. Results. VAS mean score significantly improved within the first 10 days, ranging from 8.20 ± 1.53 to 6.40 ± 1.83 (P<0.002), with a further decrease to 5.80 ± 2.04 (P<0.001) after 40 days of PEA-um administration. Moreover, NPSI total score improved from 5.2 ± 1.5 to 3.8 ± 2.1 (P: 0.025) and EQ-5D ranged from −0.30 ± 0.65 to 0.5 ± 0.34 (P<0.001) between T0 and T2. Conclusions. This study reports the prospective short-term efficacy data of oral PEA-um in patients with diabetic or traumatic NP. A significant improvement was observed both in VAS and NPSI scores and in quality of life scales after 40 days of treatment, although some limitations should be considered, including the short followup and the open-label study design

A DNA target-enrichment approach to detect mutations, copy number changes and immunoglobulin translocations in multiple myeloma.

Genomic lesions are not investigated during routine diagnostic workup for multiple myeloma (MM). Cytogenetic studies are performed to assess prognosis but with limited impact on therapeutic decisions. Recently, several recurrently mutated genes have been described, but their clinical value remains to be defined. Therefore, clinical-grade strategies to investigate the genomic landscape of myeloma samples are needed to integrate new and old prognostic markers. We developed a target-enrichment strategy followed by next-generation sequencing (NGS) to streamline simultaneous analysis of gene mutations, copy number changes and immunoglobulin heavy chain (IGH) translocations in MM in a high-throughput manner, and validated it in a panel of cell lines. We identified 548 likely oncogenic mutations in 182 genes. By integrating published data sets of NGS in MM, we retrieved a list of genes with significant relevance to myeloma and found that the mutational spectrum of primary samples and MM cell lines is partially overlapping. Gains and losses of chromosomes, chromosomal segments and gene loci were identified with accuracy comparable to conventional arrays, allowing identification of lesions with known prognostic significance. Furthermore, we identified IGH translocations with high positive and negative predictive value. Our approach could allow the identification of novel biomarkers with clinical relevance in myeloma
