Efficacy of Brivaracetam in children with epilepsy.

BACKGROUND AND OBJECTIVES: To determine the efficacy, tolerance, and safety of BRV in children with epilepsy. METHODS: A retrospective study of patients with epilepsy who received treatment with BRV before age 16 years and underwent a minimum follow-up of 3 months. METHOD AND RESULTS: Sixty-six patients were included in the study. Patients received BRV at a mean age of 8.8 years (range 1-16 years). The majority (93.4 %) had refractory epilepsy, 27 with epileptic encephalopathy. The median maximum dose used was 4.3 mg/kg/day. In 30.3 % of the cases, seizure frequency was reduced by over 50 %, and 9 % remained seizure-free. Greater efficacy was observed in those patients who received higher doses and when a direct switch from levetiracetam (LEV) to BRV was performed. The ineffectiveness of LEV was not related to a failure to respond to BRV treatment. Side effects were identified in 24.2 % of the cases, the most frequent being irritability and drowsiness. CONCLUSIONS: BRV appears to be an effective, safe, and well-tolerated AED in children with refractory epilepsy.

Comparison of neointimal hyperplasia with drug-eluting stents versus bare metal stents in patients undergoing intracoronary bone-marrow mononuclear cell transplantation following acute myocardial infarction.

The aims of this study were to assess the safety of drug-eluting stent (DES) use and to compare the incidence of in-stent restenosis (ISR) and neointimal hyperplasia formation according to the type of stent implanted (DES vs bare-metal stents [BMS]) in patients who underwent intracoronary bone marrow mononuclear cell transplantation after acute ST elevation myocardial infarction. Fifty-nine patients with successfully revascularized ST elevation myocardial infarction (37 using BMS and 22 using DES) underwent paired angiographic examinations at baseline and 6 to 9 months after the intracoronary injection of 91 million +/- 56 million autologous bone marrow mononuclear cells. A subgroup of 30 patients also underwent serial intravascular ultrasound examinations. Off-line angiographic assessment showed 4 cases of binary ISR, primarily in BMS (3 cases), and no major adverse cardiac events were associated with stent type (mean follow-up period 41 +/- 10 months). At follow-up, angiographic late luminal loss was significantly lower in patients with DES than in those patients with BMS (0.35 +/- 0.66 vs 0.71 +/- 0.38 mm, p = 0.011). Multivariate analysis identified the use of DES (beta = -0.32, 95% confidence interval [CI] -0.57 to -0.26, p = 0.03) and a smaller baseline reference vessel diameter (beta = 0.29, 95% CI 0.04 to 0.54, p = 0.02) as independent predictors of lower late loss. Moreover, intravascular ultrasound showed a significant reduction of in-stent neointimal hyperplasia formation related to DES use compared with BMS use (Delta neointimal hyperplasia volume 5.4 mm(3) [95% CI 2.7 to 28.1] vs 35.9 mm(3) [95% CI 22.0 to 43.6], p = 0.035). In conclusion, these findings suggest that the use of DES is safe and may prevent ISR and neointimal hyperplasia formation in patients who undergo intracoronary bone marrow mononuclear cell transplantation after a successfully revascularized ST elevation myocardial infarction.

Etanercept plus colchicine treatment in a child with tumour necrosis factor receptor-associated periodic syndrome abolishes auto-inflammatory episodes without normalising the subclinical acute phase response.

UNLABELLED: We investigated the cause of hereditary periodic fever syndrome in a Spanish child with recurrent long episodes of fever, migratory skin rash, myalgia, arthralgia, conjunctivitis and abdominal pain. Infectious and autoimmune causes were ruled out. No familial history was reported. Analysis of the tumour necrosis factor receptor superfamily 1A (TNFRSF1A) gene identified a missense mutation (G36E) on exon 3. The absence of this variant in the patient's parents and in controls identified it as a de novo disease-associated mutation. Clinical symptoms disappeared with administration of etanercept; however, levels of acute-phase reactants remained increased and could not be stabilised by the addition of colchicine. We believe that this patient gained some symptomatic relief with etanercept therapy, although not enough to completely avoid the risk of amyloidosis. Thus it is debatable whether etanercept alone or combined with other drugs, is the treatment of choice for patients with tumour necrosis factor receptor-associated periodic syndrome. CONCLUSION: Since there is variability in treatment responses among different patients with tumour necrosis factor receptor-associated periodic syndrome, we suggest that a systematic evaluation of acute-phase reactants, especially SAA-1, could be useful in maintaining or modifying a given therapeutic approach in these patients.

Hyper-IgM syndrome with CHARGE association.

A girl with coloboma of the iris, sensorineural deafness, growth delay, distinctive face, and cranial nerve dysfunction was diagnosed of CHARGE association in the first year of life. She presented with repeated otitis. At 3 yr of age, the patient suffered a septicemia (Streptococcus pneumoniae, Corynebacterium sp.). The immunoglobulin G (IgG) and IgA serum levels were decreased, IgM increased and cellular immunity parameters were normal, supporting the diagnosis of hyper-IgM (HIM) syndrome. The sequence of CD40 ligand and cytidine deaminase genes were normal. From then on, she was receiving immunoglobulin intravenously with an excellent outcome. Here, we report the first case of CHARGE association and HIM syndrome in the same patient. Although the cause could not be identified, a non-random link is likely.
