Analysis of thiamine transporter genes in sporadic beriberi

2014

Abstract Objective Thiamine or vitamin B 1 deficiency diminishes thiamine-dependent enzymatic activity, alters mitochondrial function, impairs oxidative metabolism, and causes selective neuronal death. We analyzed for the first time, the role of all known mutations within three specific thiamine carrier genes, SLC19 A2, SLC19 A3 , and SLC25 A19 , in a patient with atrophic beriberi, a multiorgan nutritional disease caused by thiamine deficiency. Methods A 44-year-old male alcoholic patient from Morocco developed massive bilateral leg edema, a subacute sensorimotor neuropathy, and incontinence. Despite normal vitamin B 1 serum levels, his clinical picture was rapidly reverted by high-dose in…

We analyzed for the first time the role of all known mutations within three specific thiamine carrier genes SLC19 A2 SLC19 A3 and SLC25 A19 in a patient with atrophic beriberi a multiorgan nutritional disease caused by thiamine deficiency. Methods: A 44-year-old male alcoholic patient from Morocco developed massive bilateral leg edema a subacute sensorimotor neuropathy and incontinence. Despite normal vitamin B1 serum levels his clinical picture was rapidly reverted by high-dose intramuscular thiamine treatment suggesting a possible genetic resistance. We used polymerase chain reaction followed by amplicon sequencing to study all the known thiamine-related gene mutations identified within the Human Gene Mutation Database. Results: Thirty-seven mutations were tested: 29 in SLC19 A2 6 in SLC19 A3 and 2 in SLC25 A19. Mutational analyses showed a wild-type genotype for all sequences investigated. Conclusion: This is the first genetic study in beriberi disease. We did not detect any known mutation in any of the three genes in a sporadic dry beriberi patient. We cannot exclude a role for other known or unknown mutations in the same genes or in other thiamine-associated genes in the occurrence of this nutritional neuropathy.HumansThiamineGenePolymerase chain reactionGeneticsMutationNutrition and DieteticsbiologyMembrane Transport ProteinsThiamine Deficiencymedicine.diseaseAlcoholismEndocrinologyMutationbiology.proteinThiamineMutations

Examination and treatment of sleep-related painful erections--a case report.

1989

The case of a patient with sleep-related painful erections is described. Insomnia and a slight depressive syndrome occurred along with a long history of this disorder. No physical abnormality was found. At a baseline recording of sleep electroencephalography (EEG) and nocturnal penile tumescence (NPT), a disturbed sleep pattern and impaired NPT were recorded. Attempts to treat the disorder with diazepam, amitriptyline, trimipramine, and biperidene did not prompt a stable improvement of the disorder, but a dosage of 25 mg clozapine was sufficient to achieve normalized sleep architecture, remission of the depressive symptomatology, and normalization of NPT. It is likely that marked sedation i…

Amisulpride doses and plasma levels in different age groups of patients with schizophrenia or schizoaffective disorder.

2008

Abstract Because of a unique pharmacodynamic profile, amisulpride seems appropriate for treatment of elderly patients with schizophrenia. In a large-scale naturalistic therapeutic drug monitoring study, daily amisulpride dose, trough and dose-corrected amisulpride plasma levels, co-medication, clinical effectiveness (CGI) and side effects (UKU) were compared between age groups in 395 patients with schizophrenia or schizoaffective disorder (46% women; mean age 39.1 ± 14.2 years, range 18–83 years) under amisulpride therapy. Mean amisulpride doses (574 ± 269 mg/day), plasma levels (304 ± 274 ng/mL), dose-corrected amisulpride plasma levels (C/D ratios, 0.52 ± 0.41 ng/mL:mg), clinical respons…

Effects of Nebivolol versus Carvedilol on Left Ventricular Function in Patients with Chronic Heart Failure and Reduced Left Ventricular Systolic Func…

2006

Beta-adrenoceptor antagonist (beta-blocker) therapy results in a significant improvement in left ventricular (LV) systolic function and prognosis in patients with chronic heart failure. Both carvedilol and nebivolol produce hemodynamic and clinical benefits in chronic heart failure, but it is unknown whether their peculiar pharmacologic properties produce different effects on LV function.To assess the effects on LV function of nebivolol compared with carvedilol in patients with chronic heart failure and reduced LV systolic function.Seventy patients with a LV ejection fractionor=40% and in New York Heart Association (NYHA) functional class II or III were randomly assigned to receive carvedil…

Chronic sacral spinal nerve stimulation for fecal incontinence: long-term results with foramen and cuff electrodes.

2002

PURPOSE: Sacral spinal nerve stimulation is a new therapeutic approach for patients with severe fecal incontinence owing to functional deficits of the external anal sphincter. It aims to use the morphologically intact anatomy to recruit residual function. This study evaluates the long-term results of the first patients treated with this novel approach applying two techniques of sacral spinal nerve stimulator implantation. METHODS: Six patients underwent either of two techniques for electrode placement: one “closed” (electrodes placed through the sacral foramen) and one “open” (cuff electrodes placed after sacral laminectomy). Follow-up evaluation of their continence status ranged from 5 to …

Prognostic Value of a Comprehensive Cardiac Magnetic Resonance Assessment Soon After a First ST-Segment Elevation Myocardial Infarction

2009

ObjectivesTo evaluate the prognostic value of a comprehensive cardiac magnetic resonance (CMR) assessment soon after a first ST-segment elevation myocardial infarction (STEMI).BackgroundCMR allows for a simultaneous assessment of wall motion abnormalities (WMA), WMA with low-dose dobutamine (WMA-dobutamine), microvascular obstruction, and transmural necrosis. This approach has been proven to be useful to predict late systolic recovery soon after STEMI. Its prognostic value and the relative prognostic weight of these indexes are not well-defined.MethodsWe studied 214 consecutive patients with a first STEMI treated with thrombolytic therapy or primary angioplasty discharged from hospital.

Long-term use of deferiprone significantly enhances left-ventricular ejection function in thalassemia major patients

2012

A multicenter randomized open-label long-term sequential deferiprone–deferoxamine (DFP-DFO) versus DFP alone trial (sequential DFP-DFO) performed in patients with thalassemia major (TM) was retrospectively reanalyzed to assess the variation in the left ventricular ejection fraction (LVEF) [1].

Urinary metabolites of histamine and leukotrienes before and after placebo-controlled challenge with ASA and food additives in chronic urticaria pati…

2002

Background: The recovery of mediator metabolites from urine has the potential to provide a rapid, safe, and easily available index of release of mediators. We aimed to determine urinary metabolites of both histamine and leukotrienes (LTs) in patients affected by chronic urticaria (CU). Methods: Twenty patients with CU were studied. They were selected on the basis of double-blind placebo-controlled challenge (DBPC) with acetyl salicylic acid (ASA) and food additives. Ten patients (group B) were negative to both challenges. Ten patients (group C) presented urticaria and/or the appearance of angioedema during or 24 h after challenge, with reactions to ASA (five patients) or food additives (fiv…

Pharmacokinetics of atenolol in relation to renal function

1981

The plasma levels and urinary excretion of carteolol and its main metabolites 8-hydroxycarteolol and carteolol glucuronide were investigated in 6 healthy subjects and 9 patients with varying degrees of renal impairment following a single oral dose of 30 mg carteolol hydrochloride. In healthy subjects the half-life of carteolol was 7.1 h. 63% of the administered dose was recovered unchanged in urine, and in all 84% was excreted by the kidneys. The renal clearance of carteolol was 255 ml/min. In chronic renal failure (CRF) the terminal half-life was increased to a maximum of 41 h. Both the elimination rate constant and renal clearance were closely related to the creatinine clearance. In CRF t…
