An exploratory study of serum urate levels in patients with amyotrophic lateral sclerosis.
Summary of "An exploratory study of serum urate levels in patients with amyotrophic lateral sclerosis."
Urate is a natural antioxidant, and high serum urate levels could be protective against the development of amyotrophic lateral sclerosis (ALS). To determine if serum urate concentrations were lower in ALS patients than in healthy controls, we compared serum urate levels in 132 ALS patients and 337 age/sex-matched controls. Median urate levels were lower in ALS patients compared to controls (4.2mgl/dL [range:1.4-8.2], vs. 4.7 [1.7-13.1]; p = 0.04). In univariate analysis, high urate levels were less likely to be associated with ALS (odds ratio [OR]: 0.53; 95%
0.29-0.97; p = 0.04), but after adjusting for age, sex and kidney function, the association was not statistically significant (
0.32-1.24; p = 0.18). Urate levels were lower in bulbar-onset ALS (3.9 mg/dL), compared to limb-onset ALS (4.3; p = 0.001), and in cases with longer disease duration compared to controls (4.1 mg/dL, vs. 4.7; p = 0.01). In this cross-sectional study, lower levels of serum urate were evident in ALS cases with bulbar-onset and longer disease duration, but were likely to be related to the malnutrition induced by ALS.

Medical and Biotech [MESH] Definitions
Hyperthyroxinemia, Familial Dysalbuminemic
An inherited autosomal dominant trait characterized by abnormally elevated levels of total serum THYROXINE; (T4) in euthyroid patients with abnormal SERUM ALBUMIN that binds T4 with enhanced affinity. The serum levels of free T4, free T3, and TSH are normal. It is one of several T4 abnormalities produced by non-thyroid disorder. This condition is due to mutations of the ALB gene on CHROMOSOME 4.
A uricosuric drug that is used to reduce the serum urate levels in gout therapy. It lacks anti-inflammatory, analgesic, and diuretic properties.
Thyroid Hormone Resistance Syndrome
An inherited autosomal recessive trait, characterized by peripheral resistance to THYROID HORMONES and the resulting elevation in serum levels of THYROXINE and TRIIODOTHYRONINE. This syndrome is caused by mutations of gene THRB encoding the THYROID HORMONE RECEPTORS BETA in target cells. HYPOTHYROIDISM in these patients is partly overcome by the increased thyroid hormone levels.
An enzyme that catalyzes the conversion of urate and unidentified products. It is a copper protein. The initial products decompose to form allantoin. EC 22.214.171.124.
A glutamate antagonist (RECEPTORS, GLUTAMATE) used as an anticonvulsant (ANTICONVULSANTS) and to prolong the survival of patients with AMYOTROPHIC LATERAL SCLEROSIS.
Background: Oxidative stress plays a role in the pathogenesis of neuronal death. Serum levels of urate or lipid were associated with the incidence of Parkinson's disease (PD). Objective: We compared u...
Objectives. To evaluate the person-level impact of weight loss on serum urate levels among men with a high cardiovascular risk profile. Methods. We analysed 12 379 men (mean serum urate level = 407 mu...
Dietary interventions have been suggested to be a safe cost-efficient way to control hyperuricemia. The aim of the study is to assess the potential of mediterranean diet as intervention to control the...
It is known that apoptosis may play a role in the pathophysiology of amyotrophic lateral sclerosis (ALS). Moreover, caspase-9 is implicated in the apoptosis pathway. The aim of the study was to invest...
Background: Although hyperuricemia is suggested to increase allantoin production in both pro- and antioxidant manners, it remains undetermined whether it increases the serum concentration of allantoin...
To compare the proportion of subjects whose serum urate (sUA) levels are < 6.0 mg/dL following 4 weeks of continuous treatment of RDEA594 in combination with allopurinol to allopurinol alo...
The purpose of this study is to determine the long-term safety of febuxostat compared to allopurinol in reducing serum urate levels in subjects with gout.
The purpose of this study is to determine the efficacy of febuxostat in reducing serum urate levels in subjects with gout.
The purpose of this study is to evaluate the long-term safety of febuxostat in maintaining serum urate levels within clinically acceptable levels in subjects with gout.
The objectives of this study are to determine the cerebrospinal fluid (CSF) levels of ABT-126 and to examine the effects of ABT-126 on exploratory biomarkers after administration of a sing...
