Levetiracetam, lamotrigine and carbamazepine: which monotherapy during pregnancy?

OBJECTIVE: Epilepsy treatment during pregnancy is still challenging. The study is aimed at comparing the efficacy and safety of carbamazepine (CBZ), lamotrigine (LTG) and levetiracetam (LEV) monotherapies during pregnancy in women with focal (FE) or generalized (GE) epilepsy. METHODS: A multicentre retrospective study was conducted to evaluate seizures frequency and seizure freedom (SF) rate during 3 months before pregnancy, each trimester of gestation and post-partum period in women on monotherapy with CBZ, LTG and LEV. RESULTS: Fifty-seven pregnancies (45 FE, 12 GE) on monotherapy (29 CBZ, 11 LTG, 17 LEV) were included. A significant reduction of seizure frequency was found in the first trimester of pregnancy as compared with that one before pregnancy (p = 0.004), more evident in GE (p = 0.003) and in LEV group (p = 0.004). The SF rate significantly increased in the first trimester in comparison to that one before pregnancy and persisted in the post-partum period in the whole sample (p < 0.001) and in women on LEV (p = 0.004). Besides, 88.57% of SF women before pregnancy remained unchanged during gestation and the post-partum period. One major heart malformation in CBZ and no major malformations in LTG and LEV groups were found. CONCLUSIONS: A better clinical outcome during pregnancy emerged since the first trimester in comparison to the before-pregnancy period, mostly evident in women with GE and LEV therapy, reinforcing the hypothesis of a protective role of pregnancy versus seizures. SF before pregnancy represents a significant predictive factor of good clinical outcome during gestation and the post-partum period. Compared to CBZ, LTG and LEV showed a better safety profile.

Systemic activation of Nrf2 pathway in Parkinson's disease.

BACKGROUND: Preclinical studies underlined the relevance of Nuclear factor erythroid 2-related factor 2 (Nrf2) transcription factor pathway in the pathogenesis of Parkinson's disease (PD). OBJECTIVE: The objective of this study was to explore Nrf2 pathway in vivo in PD, looking for novel disease biomarkers and therapeutic targets. METHODS: The levels of Nrf2, the downstream effectors (NAD(P)H dehydrogenase [quinone] 1 (Nqo1) enzyme, glutathione metabolism enzymes Glutamate-cysteine ligase (GCL) and Glutathione Reductase (GR)), the upstream activators (redox state and mitochondrial dysfunction), and α-synuclein oligomers were assessed in the blood leukocytes of PD patients comparatively to controls. Biochemical data were correlated to clinical parameters. RESULTS: In PD, Nrf2 was highly transcribed and expressed as well as its target effectors. The mitochondrial complex I activity was reduced and the oxidized form of glutathione prevailed, disclosing the presence of pathway's activators. Also, α-synuclein oligomers levels were increased. Nrf2 transcript and oligomers levels correlated with PD duration. CONCLUSIONS: Blood leukocytes mirror pathogenic mechanisms of PD, showing the systemic activation of the Nrf2 pathway and its link with synucleinopathy and clinical events. © 2019 International Parkinson and Movement Disorder Society.

Long-term efficacy and safety of lacosamide and levetiracetam monotherapy in elderly patients with focal epilepsy: A retrospective study.

OBJECTIVES: Epilepsy management in elderly patients is often complex because of several concomitant comorbidities that may limit the use of some antiepileptic drugs (AEDs). Levetiracetam (LEV) is a second-generation AED widely used in elderly patients with epilepsy while lacosamide (LCM), which has been recently approved in European Union (EU) as monotherapy for the treatment of focal onset seizures, is affected by a scarcity of data in such frail population. This study is aimed at assessing the efficacy and the tolerability of LCM as monotherapy in elderly patients affected by focal onset epilepsy compared with those receiving LEV. METHODS: A retrospective chart review of patients aged ≥65 years suffering from focal onset seizures, with or without secondary generalization on LCM monotherapy or LEV monotherapy, was performed. Data regarding demographic characteristics, seizure type and etiology, LCM and LEV daily dose, number of lifetime AEDs, seizure frequency at baseline and at 12 months of follow-up, and seizure freedom rates were reported. RESULTS: In this observational retrospective study, 22 patients on LCM (10 males, 12 females, mean age: 76.23 ±â€¯7.5) and 24 patients on LEV (10 males, 14 females, mean age: 73.58 ±â€¯6.39) were enrolled. Mean LCM daily dose was 204.51 ±â€¯88.51 mg and mean LEV daily dose was 1281.25 ±â€¯378.15 mg. All patients had comorbidities on chronic treatment. At 12 months of follow-up, mean monthly seizure frequency reduced from 4.23 ±â€¯8.53 to 0.33 ±â€¯0.9 (p < .001) in LCM group and from 2.29 ±â€¯6.11 to 0.2 ±â€¯0.81 (p < .001) in LEV group. Furthermore, 16/22 (72.7%) LCM patients were seizure-free at 12 months of follow-up while seizure freedom was achieved by 17/24 (70.8%) patients in LEV group. DISCUSSION AND CONCLUSION: Epilepsy management in elderly patients is often challenging. In this retrospective real-life study, the efficacy and the tolerability of LCM as monotherapy was favorable even at low doses in older patients and comparable with LEV with a high rate of long-term seizure freedom. Considering the frequent comorbidities and the risk of drug-drug interactions, LCM monotherapy may be a valuable option in elderly patients with focal onset epilepsy because of its favorable pharmacokinetic profile.

Efficacy and tolerability of perampanel and levetiracetam as first add-on therapy in patients with epilepsy: A retrospective single center study.

Perampanel (PER) is a third generation antiepileptic drug (AED), recently approved as add-on therapy in both focal and generalized seizures. Levetiracetam (LEV) is a second generation AED, widely used in patients with epilepsy because of its favorable safety and efficacy profiles. Perampanel and LEV treatments have been associated with the occurrence of similar adverse events (AEs) (sleepiness, irritability, depression, anxiety, aggressiveness). The aim of the present retrospective single center study was to verify the efficacy and tolerability of PER and LEV used as first add-on therapy in patients with epilepsy affected by secondarily generalized seizures. We collected data from 15 patients treated with PER and 26 patients treated with LEV and followed at our site with follow-up visits at 3, 6, and 12months. This retrospective study documented the comparable efficacy of PER and LEV as first add-on treatments in patients affected by uncontrolled secondarily generalized seizures. However, more patients withdrawn LEV because of AEs compared with PER at the 3- and 12-month follow-up visits. The better tolerability of PER observed in this study could be related to the low therapeutic dose of PER prescribed when it is used as first adjunctive treatment for better controlling secondarily generalized seizures.

Periodic sharp wave complexes identify a distinctive phenotype in Creutzfeldt-Jacob disease.

OBJECTIVE: The aim of our study was to evaluate the diagnostic and prognostic value of Electroencephalogram (EEG), brain Magnetic Resonance Imaging (MRI) and cerebrospinal fluid features, currently representing Creutzfeldt-Jacob Disease (CJD) diagnostic criteria. METHODS: A retrospective study on rapidly progressive dementia patients admitted at the Neurology Clinic of the University of Rome "Tor Vergata" between 2015 and 2020 was conducted. We evaluated clinical, EEG, cerebrospinal fluid and neuroradiological findings. RESULTS: Our analysis included 13 patients with probable CJD and 18 patients with non-CJD rapidly progressive dementia. Periodic sharp wave complexes were observed in 7/13 CJD and in 4/18 non-CJD patients (p =.151). The sub-analysis according to the EEG features revealed that CJD patients with earlier periodic sharp wave complexes had a significantly lower average survival time (p =.003), a shorter time to admission (p =.003) and lower levels of cerebrospinal fluid p-tau (p =.008) compared to CJD patients without periodic sharp wave complexes. Finally, they did not show signs of signal alteration on Fluid Attenuated Inversion Recovery images. CONCLUSIONS: Despite the lowest diagnostic specificity and sensibility among the CJD criteria, periodic sharp wave complexes could identify a distinctive phenotype hallmarked by a faster evolution, a reduced survival time and specific MRI and cerebrospinal fluid features. SIGNIFICANCE: The early presence of the typical EEG pattern may play a prognostic role in CJD.

18F-FDG PET, cognitive functioning, and CSF biomarkers in patients with obstructive sleep apnoea before and after continuous positive airway pressure treatment.

INTRODUCTION: Dysregulation of cerebral glucose consumption, alterations in cerebrospinal fluid (CSF) biomarkers, and cognitive impairment have been reported in patients with obstructive sleep apnoea (OSA). On these bases, OSA has been considered a risk factor for Alzheimer's disease (AD). This study aimed to measure cognitive performance, CSF biomarkers, and cerebral glucose consumption in OSA patients and to evaluate the effects of continuous positive airway pressure (CPAP) treatment on these biomarkers over a 12-month period. METHODS: Thirty-four OSA patients and 34 controls underwent 18F-fluoro-2-deoxy-D-glucose positron emission tomography (18F-FDG PET), cognitive evaluation, and CSF analysis. A subgroup of 12 OSA patients treated with beneficial CPAP and performing the 12-month follow-up was included in the longitudinal analysis, and cognitive evaluation and 18F-FDG PET were repeated. RESULTS: Significantly reduced glucose consumption was observed in the bilateral praecuneus, posterior cingulate cortex, and frontal areas in OSA patients than controls. At baseline, OSA patients also showed lower ß-amyloid42 and higher phosphorylated-tau CSF levels than controls. Increased total tau and phosphorylated tau levels correlated with a reduction in brain glucose consumption in a cluster of different brain areas. In the longitudinal analysis, OSA patients showed an improvement in cognition and a global increase in cerebral 18F-FDG uptake. CONCLUSIONS: Cognitive impairment, reduced cerebral glucose consumption, and alterations in CSF biomarkers were observed in OSA patients, which may reinforce the hypothesis of AD neurodegenerative processes triggered by OSA. Notably, cognition and brain glucose consumption improved after beneficial CPAP treatment. Further studies are needed to evaluate the long-term effects of CPAP treatment on these AD biomarkers.

Generalized Fast Discharges Along the Genetic Generalized Epilepsy Spectrum: Clinical and Prognostic Significance.

Objective: To investigate the electroclinical characteristics and the prognostic impact of generalized fast discharges in a large cohort of genetic generalized epilepsy (GGE) patients studied with 24-h prolonged ambulatory electroencephalography (paEEG). Methods: This retrospective multicenter cohort study included 202 GGE patients. The occurrence of generalized paroxysmal fast activity (GPFA) and generalized polyspike train (GPT) was reviewed. GGE patients were classified as having idiopathic generalized epilepsy (IGE) or another GGE syndrome (namely perioral myoclonia with absences, eyelid myoclonia with absences, epilepsy with myoclonic absences, generalized epilepsy with febrile seizures plus, or GGE without a specific epilepsy syndrome) according to recent classification proposals. Results: GPFA/GPT was found in overall 25 (12.4%) patients, though it was significantly less frequent in IGE compared with other GGE syndromes (9.3 vs. 25%, p = 0.007). GPFA/GPT was found independently of seizure type experienced during history, the presence of mild intellectual disability/borderline intellectual functioning, or EEG features. At multivariable analysis, GPFA/GPT was significantly associated with drug resistance (p = 0.04) and with a higher number of antiseizure medications (ASMs) at the time of paEEG (p < 0.001) and at the last medical observation (p < 0.001). Similarly, GPFA/GPT, frequent/abundant generalized spike-wave discharges during sleep, and a higher number of seizure types during history were the only factors independently associated with a lower chance of achieving 2-year seizure remission at the last medical observation. Additionally, a greater number of GPFA/GPT discharges significantly discriminated between patients who achieved 2-year seizure remission at the last medical observation and those who did not (area under the curve = 0.77, 95% confidence interval 0.57-0.97, p = 0.02). Conclusion: We found that generalized fast discharges were more common than expected in GGE patients when considering the entire GGE spectrum. In addition, our study highlighted that GPFA/GPT could be found along the entire GGE continuum, though their occurrence was more common in less benign GGE syndromes. Finally, we confirmed that GPFA/GPT was associated with difficult-to-treat GGE, as evidenced by the multivariable analysis and the higher ASM load during history.

[The treatment of acute psychotic episode: discrepancy between routine practice and evidence. The Project SIEP-DIRECT'S]. / Il trattamento dell'episodio psicotico acuto: discrepanze fra pratiche di routine ed evidenze. Il Progetto SIEP-DIRECT'S.

AIMS: To evaluate the quality of psychiatric care during the acute psychotic episode and the early post-acute period. METHODS: Data concerning 24 indicators, drawn from NICE recommendations, were collected in 19 Departments of Mental Health, in the frame of the SIEP-DIRECT'S Project to evaluate the implementation of NICE recommendations in Italian Mental Health Services. RESULTS: The treatment of the acute episode in the Italian Mental Health Services is not based only on admissions in Psychiatric Ward in General Hospitals, but also on intensive home based care. The utilization of day hospital facilities for treating acute episodes is less frequent, as the presence of home based follow up after discharge. About 3/4 of Departments of Mental Health did not have clinical guidelines concerning the pharmacological treatment in this area. However usually the standard practices followed NICE recommendations in terms of prescribed dosages, monitoring side effects and rationale for shifting to atypical antipsychotic drugs. Antipsychotic drugs, atypical or conventional, were frequently prescribed concurrently, while utilization of atypical antipsychotic drugs was increasing. CONCLUSIONS: The results show critical points concerning on one hand the scarce diffusion of clinical guidelines, on other hand the connection between standard practices, clinical guidelines and marketing of atypical antipsychotic drugs. It should be reinforced the role of the community and particularly at service level the capacity of community mental health teams to treat the acute patients.

[Multiple colonic anastomoses in the surgical treatment of short bowel syndrome. A new technique]. / Anastomosis colónica múltiple en el tratamiento quirúrgico del intestino corto. Una nueva técnica.

BACKGROUND: Some surgical pathologies eventually require intestinal resection. This may lead to an extended procedure such as leaving 30 cm of proximal jejunum and left and sigmoid colon. One of the most important consequences of this type of resection is "intestinal failure" or short bowel syndrome. This complex syndrome leads to different metabolic and water and acid/base imbalances, as well as nutritional and immunological challenges along with the problem accompanying an abdomen subjected to many surgical procedures and high mortality. Many surgical techniques have been developed to improve quality of life of patients. METHODS: We designed a non-transplant surgical approach and performed the procedure on two patients with postoperative short bowel syndrome with <40 cm of proximal jejunum and left colon. RESULTS: There are a variety of non-transplant surgical procedures that, due to their complex technique or high mortality rate, have not resolved this important problem. However, the technique we present in this work can be performed by a large number of surgeons. The procedure has a low morbimortality rate and offers the opportunity for better control of metabolic and acid/base balance, intestinal transit and proper nutrition. CONCLUSIONS: We consider that this technique offers a new alternative for the complex management required by patients with short bowel syndrome and facilitates their long-term nutritional control.
