RESUMO

Nonalcoholic steatohepatitis (NASH), a chronic liver disease without an approved therapy, is associated with lipotoxicity and insulin resistance and is a major cause of cirrhosis and hepatocellular carcinoma. Aramchol, a partial inhibitor of hepatic stearoyl-CoA desaturase (SCD1) improved steatohepatitis and fibrosis in rodents and reduced steatosis in an early clinical trial. ARREST, a 52-week, double-blind, placebo-controlled, phase 2b trial randomized 247 patients with NASH (n = 101, n = 98 and n = 48 in the Aramchol 400 mg, 600 mg and placebo arms, respectively; NCT02279524 ). The primary end point was a decrease in hepatic triglycerides by magnetic resonance spectroscopy at 52 weeks with a dose of 600 mg of Aramchol. Key secondary end points included liver histology and alanine aminotransferase (ALT). Aramchol 600 mg produced a placebo-corrected decrease in liver triglycerides without meeting the prespecified significance (-3.1, 95% confidence interval (CI) -6.4 to 0.2, P = 0.066), precluding further formal statistical analysis. NASH resolution without worsening fibrosis was achieved in 16.7% (13 out of 78) of Aramchol 600 mg versus 5% (2 out of 40) of the placebo arm (odds ratio (OR) = 4.74, 95% CI = 0.99 to 22.7) and fibrosis improvement by ≥1 stage without worsening NASH in 29.5% versus 17.5% (OR = 1.88, 95% CI = 0.7 to 5.0), respectively. The placebo-corrected decrease in ALT for 600 mg was -29.1 IU l-1 (95% CI = -41.6 to -16.5). Early termination due to adverse events (AEs) was <5%, and Aramchol 600 and 400 mg were safe, well tolerated and without imbalance in serious or severe AEs between arms. Although the primary end point of a reduction in liver fat did not meet the prespecified significance level with Aramchol 600 mg, the observed safety and changes in liver histology and enzymes provide a rationale for SCD1 modulation as a promising therapy for NASH and fibrosis and are being evaluated in an ongoing phase 3 program.

RESUMO

INTRODUCTION AND AIMS: Helicobacter pylori (H. pylori) infection remains the leading cause of several gastroduodenal diseases. Despite the fact that multiple antibiotic regimens have been used to change its associated morbidity and mortality, the prevalence of this bacterial infection continues to be disproportionately high worldwide, mainly due to antibiotic resistance. To assess the noninferiority efficacy and safety of 210-day triple regimens on H. pylori eradication, we evaluated clarithromycin 500mg, lansoprazole 30mg, and amoxicillin 1g, all bid (standard triple therapy or CLA, Group 1) vs. pantoprazole 80mg, levofloxacin 500mg and azithromycin 500mg, all od (PLA, Group 2). Both regimens were compared in treatment-naïve patients. MATERIALS AND METHODS: An open label phase IIIb randomized and noninferiority trial comparing CLA vs. PLA was carried out for a 10-day period, within the time frame of June 2012 and March 2014. Eradication was verified with 13C-urea breath testing. Gastric biopsies were tested for fluorescence in situ hybridization (FISH)-clarithromycin resistance prior to any antibiotic administration. Efficacy and safety results were analyzed according to the noninferiority methodological approach. RESULTS: From the 227 H. pylori positive subjects that were randomized, 194 were finally analyzed as per-protocol. The group 2 eradication rate was 63% and was noninferior to the group 1 eradication rate of 58.5% (upper limit 95% CI: 0.11608; below the noninferiority margin: 0.1200). FISH clarithromycin-resistance was found in 28.2% of the cases. Adverse events, all minor and self-limited, were significantly higher in group 1 than in group 2 (86 vs. 65.4%; p=0.001). CONCLUSIONS: First-line H. pylori eradication with pantoprazole/levofloxacin/azithromycin combination therapy is as effective as the standard triple therapy, with better tolerability and easier dosing. Clarithromycin resistance should be considered when selecting antibiotics in Helicobacter pylori eradication treatments. ClinicalTrials.gov identifier NCT02726269.

RESUMO

BACKGROUND: GIDEON (Global Investigation of therapeutic DEcisions in hepatocellular carcinoma [HCC] and Of its treatment with sorafeNib) is a global, prospective, non-interventional study undertaken to evaluate the safety of sorafenib in patients with unresectable HCC in real-life practice, including Child-Pugh B patients who were excluded from clinical trials. METHODS: Patients with unresectable HCC, for whom the decision to treat with sorafenib, based on the approved label and prescribing guidelines, had been taken by their physician, were eligible for inclusion. Demographic data and disease/medical history were recorded at entry. Sorafenib dosing and adverse events (AEs) were collected at follow-up visits. The second interim analysis was undertaken when ~1500 treated patients were followed up for ≥ 4 months. RESULTS: Of the 1571 patients evaluable for safety, 61% had Child-Pugh A status and 23% Child-Pugh B. The majority of patients (74%) received the approved 800 mg initial sorafenib dose, regardless of Child-Pugh status; however, median duration of therapy was shorter in Child-Pugh B patients. The majority of drug-related AEs were grade 1 or 2, and the most commonly reported were consistent with previous reports. The incidence and nature of drug-related AEs were broadly similar across Child-Pugh, Barcelona Clinic Liver Cancer (BCLC) and initial dosing subgroups, and consistent with the overall population. CONCLUSIONS: Consistent with the first interim analysis, overall safety profile and dosing strategy are similar across Child-Pugh subgroups. Safety findings also appear comparable irrespective of initial sorafenib dose or BCLC stage. Final analyses in > 3000 patients are ongoing.

RESUMO

AIMS: Global Investigation of therapeutic DEcisions in hepatocellular carcinoma and Of its treatment with sorafeNib (GIDEON), a global, non-interventional, surveillance study, aims to evaluate the safety of sorafenib in all patients with unresectable hepatocellular carcinoma (uHCC) under real-life practice conditions, particularly Child-Pugh B patients, who were not well represented in clinical trials. METHODS: Treatment decisions are determined by each physician according to local prescribing guidelines and clinical practice. Patients with uHCC who are candidates for systemic therapy, and for whom a decision has been made to treat with sorafenib, are eligible for inclusion. Demographic data and medical and disease history are recorded at entry. Sorafenib dosing and adverse events (AEs) are collected throughout the study. RESULTS: From January 2009 to April 2011, >3000 patients from 39 countries were enrolled. The prespecified first interim analysis was conducted when the initial approximately 500 treated patients had been followed up for ≥4 months; 479 were valid for safety evaluation. Preplanned subgroup analyses indicate differences in patient characteristics, disease aetiology and previous treatments by region. Variation in sorafenib dosing by specialty are also observed; Child-Pugh status did not appear to influence the starting dose of sorafenib. The type and incidence of AEs was consistent with findings from previous clinical studies. AE profiles were comparable between Child-Pugh subgroups. DISCUSSION: The GIDEON study is generating a large, robust database from a broad population of patients with uHCC. First interim analyses have shown global and regional differences in patient characteristics, disease aetiology and practice patterns. Subsequent planned analyses will allow further evaluation of early trends.

RESUMO

INTRODUCTION: Landau-Kleffner syndrome is characterised by acquired aphasia and encephalographic alterations that may or may not be accompanied by epileptic seizures. AIM. To analyse the clinical and encephalographic features and response to treatment of 10 patients with Landau-Kleffner syndrome. PATIENTS AND METHODS: We reviewed the patient records, encephalograms and treatment administered to patients catalogued as having Landau-Kleffner syndrome. RESULTS: The mean age of the patients was 44 months. Of these cases, 60% presented epilepsy when the diagnosis was established and 70% were found to have epileptic status during slow-wave sleep in the encephalographic study. Results showed that 40% corresponded to variants of Landau-Kleffner syndrome. No cause of the disease could be established in any of the patients. In the neuroimaging study, only one patient displayed abnormalities in the magnetic resonance imaging of the brain. All the patients received adrenocorticotropic hormone (ACTH)-based treatment, at a dose of 1 IU/kg/day for one month, administered together with antiepileptic drugs such as valproic acid and clobazam. Convulsive seizures and epileptic status during slow-wave sleep disappeared in all the patients. In the patients without epileptic status, epileptic activity became less frequent, although it did not completely disappear. Aphasia improved considerably, which meant that all the patients were able to enroll in normal schools. CONCLUSIONS: We believe that early diagnosis, together with suitable and timely management of aphasic patients with encephalographic alterations that allow ACTH to be used at low doses, make it possible to offer an early education so as to provide maximum recovery from the disease.

RESUMO

INTRODUCTION: Alternating hemiplegia (AH) of childhood is a rare disease that gives rise to transient attacks of hemiplegia that may affect either side of the body indistinctly, or even both sides at the same time. Onset occurs before the age of 18 months and in some cases there are neonatal symptoms such as abnormal eye movements, especially nystagmus, and dystonic or tonic seizures. Attacks of hemiplegia, which disappear during sleep, begin before the age of one year. These symptoms can initially be taken for an epileptic disorder. CASE REPORTS: We describe the study of two male patients whose clinical symptoms appeared at the age of 6 months, with tonic seizures, upward deviation of gaze, without loss of consciousness, which occurred with a recurrence rate of between one and two attacks a week or several times a day. They were initially treated with antiepileptic drugs (AED), although the complementary tests, including electroencephalogram (EEG), computerised axial tomography (TAC), magnetic resonance (MR) scans and metabolic tests, were all normal. CONCLUSIONS: Since, to date, no specific test has been confirmed for the disease, diagnosis is essentially clinical and by exclusion. Treatment is symptomatic using flunarizine. In one of our cases, administration of a single 10 mg/day dose this drug at night lowered the frequency of the attacks of hemiplegia. The possibility of treating a patient who is a carrier of an AH with AED makes early knowledge and identification of this disease necessary in order to be able to improve the patient's prognosis.

RESUMO

INTRODUCTION: Organic acidurias have long been known to cause neurological problems, such as convulsions, stupor, coma, and psychomotor and mental retardation. The organic acidurias include propionic aciduria, methylmalonic aciduria (MMA), isovaleric acidemia, lactic acidemia and glutaric acidemia type I. However, the association of MMA with electrical activity of the brain characterised by a hypsarrhythmic pattern, refractory convulsions and psychomotor retardation is very rare. CASE REPORTS: Two patients, one male and one female, were seen to have psychomotor retardation, erratic attacks of myoclonic convulsions, hypsarrhythmic encephalographic pattern and an increase in the urinary excretion of methylmalonic acid, as shown by gas chromatography and mass spectrometry, all of which supported a diagnosis of MMA in both cases. In one patient, the brain MRI with gadolinium showed lesions compatible with brain atrophy. Protein restrictions, the administration of vitamin B12 and l carnitine re established the normal neurological state and reduced the urinary excretion of methylmalonic acid in one of them. CONCLUSIONS: To the best of our knowledge these are the first cases of MMA that have been seen accompanied by hypsarrhythmia. The rareness of this clinical presentation with the characteristics described above make us suspect that we are dealing with a new clinical syndrome.
