Epilepsia y gestación. Factores asociados con la presencia de crisis en la gestación / Epilepsy and pregnancy. Factors associated with epileptic seizures during pregnancy

Introducción: El manejo de la epilepsia durante la gestación requiere un control óptimo de las crisis, evitando los potenciales efectos teratogénicos del tratamiento antiepiléptico.ObjetivosDescribir las características clínicas y los resultados perinatales de las pacientes con epilepsia gestantes. Analizar los factores que se asocian a la presencia de crisis durante la gestación. Describir los fármacos antiepilépticos más utilizados y analizar los cambios en el régimen terapéutico en dos periodos: de 2000-2010 y 2011-2018.MétodosSe realizó un estudio prospectivo observacional de pacientes con epilepsia que notificaron su gestación en el periodo de 2000-2018. Se evaluó a las pacientes en el primer y segundo trimestre de gestación, tras el parto y al año. Se recogieron variables demográficas, relacionadas con la epilepsia, perinatales y obstétricas.ResultadosSe incluyeron 101 gestaciones. La edad media fue de 32,6 años, el 55,4% tenía una epilepsia focal, el 38,6% una epilepsia generalizada y el 5,9% indeterminada. Se registraron 90 nacidos vivos, nueve abortos espontáneos y cinco malformaciones congénitas, cuatro de ellas en monoterapia con valproato. En 40 gestaciones (39,6%) se registraron crisis, siendo tónico-clónicas generalizadas en 16 (40%). Las variables asociadas con la presencia de crisis durante el embarazo fueron el mal control el año previo a la gestación (66,7% vs. 15,1%, p < 0,001), el tratamiento con dos o más fármacos antiepilépticos (30% vs. 14,8% p < 0,001) y no recibir tratamiento (25% vs. 0% p < 0,001). Los fármacos antiepilépticos más utilizados en monoterapia fueron lamotrigina (n = 19, 27,1%), valproato (n = 17, 24,2%) y levetiracetam (n = 12, 17,1%). En el periodo más reciente (2011-2018) se encontró una mayor proporción de monoterapias (81,5% vs. 55,3%), además de un descenso en el uso de carbamazepina (23,1% vs. 2,3%) y valproato (30,8% vs. 20,5%); y un aumento marcado de levetiracetam (0% vs. 27,3%).

Patients were evaluated in the first and second trimesters of pregnancy, after delivery, and at one year. Data were collected on demographic variables, epilepsy, and perinatal and obstetric variables.ResultsA total of 101 pregnancies were included. Patients’ mean age was 32.6 years; 55.4% had focal epilepsy, 38.6% had generalised epilepsy, and 5.9% had undetermined epilepsy. We recorded 90 live births, 9 miscarriages, and 5 cases of congenital malformations, 4 of which were born to women who received valproate monotherapy. Forty patients (39.6%) presented seizures, with 16 (40%) presenting generalised tonic-clonic seizures. The variables associated with seizures during pregnancy were poor seizure control in the year prior to pregnancy (66.7% vs. 15.1%; P < .001), treatment with 2 or more antiepileptic drugs (30% vs. 14.8%; P < .001), and untreated epilepsy (25% vs. 0%; P < .001). The antiepileptic drugs most widely used in monotherapy were lamotrigine (n = 19; 27.1%), valproate (n = 17; 24.2%), and levetiracetam (n = 12; 17.1%). In the most recent period (2011-2018), we observed a greater proportion patients receiving monotherapy (81.5%, vs. 55.3%), as well as a decrease in the use of carbamazepine (2.3%, vs. 23.1%) and valproate (20.5%, vs. 30.8%); and a marked increase in the use of levetiracetam (27.3%, vs. 0%).

El insomnio y la pobre calidad de sueño se asocian a un mal control de crisis en pacientes con epilepsia / Insomnia and poor sleep quality are associated with poor seizure control in patients with epilepsy

Objetivos: Evaluamos la presencia de trastornos del sueño en pacientes con epilepsia y analizamos su asociación con el control de las crisis.MétodosSe realizó un estudio transversal de pacientes con epilepsia reclutados consecutivamente entre septiembre de 2017 y diciembre de 2018. Los pacientes se clasificaron en 2 grupos según el control de crisis (buen control: pacientes sin crisis en las últimas 4 semanas) o mal control (pacientes con una crisis o más en las últimas 4 semanas). Se compararon variables demográficas y clínicas; insomnio, medido por el Índice de Severidad del Insomnio (ISI); somnolencia diurna excesiva, medida por la Escala de Somnolencia de Epworth (ESS); calidad del sueño, medida por el Índice de Calidad del Sueño de Pittsburgh (PSQI); depresión, medida por el Inventario de Depresión de Beck-II (BDI-II); y calidad de vida, medida por el test de Calidad de Vida en Epilepsia (QOLIE-10).ResultadosSe incluyeron 123 pacientes. El 31,7% tenía somnolencia diurna excesiva (ESS ≥ 10), el 50,4% insomnio (ISI ≥ 10) y el 53,6% mala calidad del sueño (PSQI ≥ 5). Los factores asociados con la presencia de crisis fueron el desempleo (odds ratio [OR] = 4,7; intervalo de confianza del 95% [IC 95%]: 1,36-19,2; p = 0,02), un mayor número de fármacos antiepilépticos (OR = 5,87; IC 95%: 1,81-27,1; p < 0,001), insomnio (OR = 1,9; IC 95%: 1,1-9,3; p = 0,04) y mala calidad del sueño (OR = 2,8; IC 95%: 1,9-10,32; p = 0,01).ConclusionesLos trastornos del sueño son frecuentes en pacientes con epilepsia. El insomnio y la mala calidad del sueño se asociaron con un peor control de crisis. Estos hallazgos apoyan que los trastornos del sueño son una comorbilidad frecuente en epilepsia, especialmente en pacientes con peor control de crisis. (AU)

Objectives: This study aimed to assess the presence of sleep disorders in patients with epilepsy and to analyse their association with seizure control.MethodsWe performed a cross-sectional study of patients with epilepsy, recruited consecutively between September 2017 and December 2018. Patients were classified as having good seizure control (no seizures in the last 4 weeks) or poor seizure control (at least one seizure in the last 4 weeks). We performed intergroup comparisons for demographic and clinical data, insomnia (Insomnia Severity Index [ISI]), excessive daytime sleepiness (Epworth Sleepiness Scale [ESS]), sleep quality (Pittsburgh Sleep Quality Index [PSQI]), depression (Beck Depression Inventory-II [BDI-II]), and quality of life (Quality of Life in Epilepsy Inventory-10 [QOLIE-10]).ResultsThe sample included a total of 123 patients, of whom 31.7% had excessive daytime sleepiness (ESS ≥ 10), 50.4% had insomnia (ISI ≥ 10), and 53.6% had poor sleep quality (PSQI ≥ 5). According to our multivariate analysis, presence of seizures was associated with unemployment (odds ratio [OR] = 4.7; 95% confidence interval [CI], 1.36-19.2; P = .02), a higher number of antiepileptic drugs (OR = 5.87; 95% CI, 1.81-27.1; P < .001), insomnia (OR = 1.9; 95% CI, 1.1-9.3; P = .04), and poor sleep quality (OR = 2.8; 95% CI, 1.9-10.32; P = .01).ConclusionsSleep disorders are common in patients with epilepsy. Insomnia and poor sleep quality were associated with poor seizure control. These findings support the hypothesis that sleep disorders constitute a significant comorbidity of epilepsy, especially in patients with poor seizure control. (AU)

The impact of insomnia disorder on adult attention-deficit/hyperactivity disorder severity: A six-month follow-up study.

BACKGROUND AND OBJECTIVES: The longitudinal relationship between insomnia disorder and adult attention-deficit/hyperactivity disorder (ADHD) has been scarcely investigated. This study aimed to evaluate the relationship between the remission of insomnia disorder and adult ADHD clinical severity, psychiatric and medical comorbidities, and the health-related quality of life (HRQoL) in a 6-month follow-up. METHODS: Ninety-two adult patients with ADHD and insomnia disorder (52.2% males; mean age 39.5 ± 11.0 years) were comprehensively assessed at baseline, 3 months, and 6 months of a follow-up period. The evaluation included semi-structured interviews (for ADHD and comorbidity assessment), the Pittsburgh Sleep Quality Index, Insomnia Severity Index, and Epworth Sleepiness Scale. The diagnosis of ADHD and insomnia disorder was performed according to DSM-5 criteria. At baseline and follow-up, psychoeducation/sleep hygiene and, if necessary, pharmacological were prescribed for insomnia. RESULTS: Eighty-seven patients completed the 6-month follow-up. Insomnia disorder remission was reported in 72.4% of cases and was related to a greater improvement in ADHD symptoms and severity throughout the follow-up period. Additionally, an improvement in psychiatric comorbidities and better HRQoL were associated with insomnia disorder remission. CONCLUSION: The current study highlights that the treatment of insomnia disorder in ADHD adult patients may have an important role in the outcome of ADHD therapeutic approaches by reducing their severity.

Psychosis after buprenorphine, heroin, methadone, morphine, oxycodone, and tramadol withdrawal: a systematic review.

OBJECTIVE: This study's main objective is to carry out a systematic review of the onset of psychotic symptoms after opioid withdrawal. The opiate dependence correlated to psychiatric symptoms has been well described. MATERIALS AND METHODS: Following the PRISMA methodology. The consecutive search strategy was applied: (morphine OR buprenorphine OR oxycodone OR tramadol OR fentanyl OR remifentanil OR opioids OR heroin OR methadone) AND (Psychosis OR psychotic symptoms OR schizophrenia). RESULTS: 12 case reports, 3 series of cases, 2 clinical studies, and 2 reviews were found. It seems that the time association is present in all of them; symptoms appear days after the interruption of the opioid. Most of the articles reported are case reports that describe symptoms that appear after the suspension of the opioid substance; in most cases, the reintroduction of the opioid had therapeutic effects and provoked a remission of these symptoms. These preliminary findings indicate that opiates could have an antipsychotic effect; however, the literature is scarce. It is critical to consider, if needed, in opioid-dependent patients who start with psychosis after the opioid withdrawal the possible replacement or reintroduction of opioids to prevent further deterioration in the patient's mental status. CONCLUSIONS: This study encompasses a comprehensive description of the literature concerning the possible not well-studied outcome of opioid withdrawal. There are some reports of temporal association between withdrawal and psychotic symptoms that improved after the reintroduction of the opioid; it could be taken into consideration in the clinical practice.

[Drug-induced mania and hypomania: analysis of a case of lamotrigine-induced mania]. / Manía e hipomanía inducida por fármacos: análisis de un caso de manía inducida por lamotrigina.

INTRODUCTION: Lamotrigine is an antiepileptic medication approved as a mood stabilizer for the prevention of depressive episodes in bipolar disorder. Among its adverse reactions, it may present maniac symptoms, despite being an idiosyncratic adverse effect and low incidence. CASE REPORT: We present the case of a 58-year-old patient, diagnosed with bipolar disorder since her youth and who has required multiple therapeutic schemes. After a pharmacological change from lithium to lamotrigine in progressive ascending doses, she presented a mania decompensation, temporally consistent with the initiation of lamotrigine, and that was accentuated with increasing dose. The symptoms disappear when lamotrigine is withdrawn and a pharmacological approach is carried out. When evaluating the case according to the causality criteria of Naranjo et al, we found a possible result. CONCLUSION: Although lamotrigine-induced manifest symptoms have been previously documented, it is important to take this adverse effect into account, given the affective and behavioral repercussions. Further studies are needed to understand the bilateral relationship of this effect from a clinical and neurobiological point of view.

TITLE: Manía e hipomanía inducida por fármacos: análisis de un caso de manía inducida por lamotrigina.Introducción. La lamotrigina es un antiepiléptico aprobado como estabilizador del ánimo para la prevención de episodios depresivos en el trastorno bipolar. Entre sus reacciones adversas puede presentar sintomatología maniforme inducida, a pesar de ser un efecto adverso de carácter idiosincrático y baja incidencia. Caso clínico. Presentamos el caso de una paciente de 58 años, con diagnóstico de trastorno bipolar desde su juventud y que, a lo largo de la evolución de su patología, ha precisado múltiples esquemas terapéuticos. Tras un cambio farmacológico de litio a lamotrigina en dosis ascendentes progresivas, presenta descompensación maniforme, concordante temporalmente con el inicio de la lamotrigina y que se acentúa con el aumento de la dosis. La sintomatología desaparece al retirar la lamotrigina y realizar un abordaje farmacológico. Al evaluar el caso según los criterios de causalidad de Naranjo et al, encontramos un resultado posible. Conclusión. Aunque se ha documentado previamente sintomatología maniforme inducida por lamotrigina, es importante tener en cuenta este efecto adverso, dada la repercusión a nivel afectivo y conductual. Son necesarios más estudios para entender la relación bilateral de este efecto desde un punto de vista clínico y neurobiológico.

Epilepsy and pregnancy. Factors associated with epileptic seizures during pregnancy. / Epilepsia y gestación. Factores asociados con la presencia de crisis en la gestación.

INTRODUCTION: The management of epilepsy during pregnancy requires optimal seizure control, avoiding the potential teratogenic effects of antiepileptic drugs. OBJECTIVES: This study aims to describe the clinical characteristics and perinatal outcomes of pregnant patients with epilepsy; to analyse the factors associated with seizures during pregnancy; to describe the most commonly used antiepileptic drugs in these patients; and to analyse changes in treatment regimens in 2 periods, 2000-2010 and 2011-2018. METHODS: We conducted a prospective observational study of patients with epilepsy who reported their pregnancy between 2000 and 2018. Patients were evaluated in the first and second trimesters of pregnancy, after delivery, and at one year. Data were collected on demographic variables, epilepsy, and perinatal and obstetric variables. RESULTS: A total of 101 pregnancies were included. Patients' mean age was 32.6 years; 55.4% had focal epilepsy, 38.6% had generalised epilepsy, and 5.9% had undetermined epilepsy. We recorded 90 live births, 9 miscarriages, and 5 cases of congenital malformations, 4 of which were born to women who received valproate monotherapy. Forty patients (39.6%) presented seizures, with 16 (40%) presenting generalised tonic-clonic seizures. The variables associated with seizures during pregnancy were poor seizure control in the year prior to pregnancy (66.7% vs. 15.1%; P < .001), treatment with 2 or more antiepileptic drugs (30% vs. 14.8%; P < .001), and untreated epilepsy (25% vs. 0%; P < .001). The antiepileptic drugs most widely used in monotherapy were lamotrigine (n = 19; 27.1%), valproate (n = 17; 24.2%), and levetiracetam (n = 12; 17.1%). In the most recent period (2011-2018), we observed a greater proportion patients receiving monotherapy (81.5%, vs. 55.3%), as well as a decrease in the use of carbamazepine (2.3%, vs. 23.1%) and valproate (20.5%, vs. 30.8%); and a marked increase in the use of levetiracetam (27.3%, vs. 0%). CONCLUSIONS: The factors associated with the presence of seizures during pregnancy were previous poor seizure control, treatment with 2 or more antiepileptic drugs, and lack of treatment during pregnancy. The most commonly used drugs were lamotrigine, valproate, and levetiracetam, with an increase in levetiracetam use and a decrease in valproate use being observed in the later period (2011-2018).

Pharmacological Treatment of Insomnia Symptoms in Individuals with Substance Use Disorders in Spain: A Quasi-Experimental Study.

INTRODUCTION: Pharmacological treatment of insomnia in patients with addictions has been hardly investigated and there are few researches about it in an inpatient detoxification. The aim of this study was to describe the outcomes of the pharmacological treatment of insomnia in SUD patients admitted to a detoxification unit in Spain, with a focus on the primary substance of abuse and co-occurring mental disorders. METHODS: A quasi-experimental study was conducted in 481 addicted in patients, who were admitted for substances detoxification in Vall d´Hebron University Hospital, Barcelona, Spain, from 2010 to 2015. The patients underwent systematic evaluation of axes I and II psychiatric disorders (SCID-I, SCID-II, and CAADID). Insomnia was evaluated using a night time sleep log. Substance-dependent patients, who had insomnia during hospital detoxification, received a psychotropic medication with hypnotic effect, keeping the regular clinical practice without randomization. RESULTS: At discharge, insomnia was considered to have been alleviated in 63.8% (n = 204) of patients while 36.2% (n = 116) of patients remained with insomnia disturbances. Comparing hypnotic treatments it was observed that mirtazapine and clotiapine were the treatment that corrected the insomnia more frequently. DISCUSSION: Since insomnia is not corrected in all patients, it should be further investigated in medications with hypnotic purpose. Based on the results of this work, randomized clinical trials might be proposed.

Higher severity of cocaine addiction is associated with tactile and somatic hallucinations.

BACKGROUND: The aim of this study is to describe the features of cocaine-dependent patients who have had cocaine-induced tactile/somatic hallucinations (CITSH), and to analyze the association with addiction-related variables and psychiatric comorbidity, comparing patients with CITSH, patients with cocaine psychotic symptoms (CIP) and no CITSH, and patients without any psychotic symptom. METHOD: A cross-sectional study was conducted in 767 cocaine-dependent patients in an outpatient treatment center for addictions. The following data were obtained: sociodemographic characteristics, CIP information, addiction-related variables and psychiatric comorbidity. A bivariate and multivariate analysis was performed. RESULTS: Of the whole sample, 6.6% reported CITSH at some point of their lives, 48.4% had suffered some CIP other than CITSH, and 45% had not experienced any psychotic symptom. According to multivariate analysis, risk of overdose increases by 12.1 (OR) times the probability of having had CITSH compared patients with CIP-no-CITSH. Other variables associated to patients with CITSH were: age of drug use onset, presence of episodes of overdose, prevalence of psychotic disorder induced by cocaine. In general, in all variables studied, patients with CITSH presented worse clinical features (addiction variables and psychiatric comorbidity) than patients with CIP without CITSH and non-CIP group. CONCLUSION: CITSH are usually associated with other psychotic symptoms induced by cocaine. The patients who experienced CITSH are more severe cases compared both with patients with CIP without CITSH and patients without CIP. Increased risk of overdose is an important issue in this type of patients.
