lactic acid and Ataxia with Lactic Acidosis

lactic acid has been researched along with Ataxia with Lactic Acidosis in 43 studies

Lactic Acid: A normal intermediate in the fermentation (oxidation, metabolism) of sugar. The concentrated form is used internally to prevent gastrointestinal fermentation. (From Stedman, 26th ed)
2-hydroxypropanoic acid : A 2-hydroxy monocarboxylic acid that is propanoic acid in which one of the alpha-hydrogens is replaced by a hydroxy group.

Trial Outcomes

McMaster Gross Motor Function (GMFM 88)

The McMaster Gross Motor Function is a validated scale ranging from 0 to 100 (the higher the better). Since there was the possibility of a subject becoming totally disabled our FDA peer reviewed design called for its use as follows: If the subject completed both periods, the score was calculated as the difference in scores between the end of Period 2 (at 12 months) minus that at the end of Period 1 (6 months). If a subject became totally disabled, this difference was considered as plus infinity if it occurred in period 1 (Penalizes period 1), and minus infinity if it occurred in Period 2 (Penalizes period 2). The two treatments were compared via the Wilcoxon test, and the effect size was estimated using Kendall's Tau-B. This is interpreted in a similar manner to correlation with positive values favoring COQenzyme10 and negative values favoring placebo. One of the links in this report is to the the GMFM scale and how it is scored. A link to the instrument is included. (NCT00432744)

Non-parametric Hotelling T-square Bivariate Analysis of GMGF 88 and OPeds QOL.

This is a multivariate analysis of the first two outcomes: Period 2 minus Period 1 GMFM88 and Peds Quality of Life, analyzed as follows: First, to be in the analysis, subjects must contribute at least one of these endpoints. Second, if the subject became totally disabled during period 1, the difference was defined as + infinity, (highest possible evidence favoring period 2), and if the subject became totally disabled in period 2, the subject was scored as - infinity (highest possible evidence favoring period 1). Period 2 minus period 1 differences were ranked form low to high with missing values scores at the mid-rank. The Hotelling T-square was computed on these ranks and the P-value was obtained from 100,000 rerandomizations as the fraction of rerandomizations with T-sq at least as large as that observed. (NCT00432744)
Timeframe: end of 12 month minus end of 6 month difference.

Pediatric Quality of Life Scale

"The Pediatric Quality of Life Scale is a validated scale ranging from 0 to 100 (the higher the better). Since there was the possibility of a subject becoming totally disabled our FDA peer reviewed design called for its use as follows: If the subject completed both periods, the score was calculated as the difference in scores between the end of Period 2 (at 12 months) minus that at the end of Period 1 (6 months).
