Clinical Trial of Docosahexaenoic Acid in Patients With Retinitis PigmentosaReceiving Vitamin A Treatment

Abstract: To determine whether a therapeutic dose of docosahexaenoic acid (DHA), an-3 fatty acid, will slow the course of retinal degeneration in adult patients with retinitis pigmentosa who are also receiving vitamin A. Design: Randomized, controlled, double-masked trial of 221 patients, aged 18 to 55 years, evaluated over a 4-year interval. Patients were given either 1200 mg/d of docosahexaenoic acid or control capsules. All were given 15000 IU/d of vitamin A (given as retinyl palmitate). Randomization considered gene… Show more

“…Indeed, because RP shows a definite but slow decline in visual function and degeneration of retinal structure, large clinical trials have set study periods for longer than 4 years, although their outcomes were different from those of this study. [21][22][23] We converted the length of ISe to rate (%) to exclude the effect of the length of ISe, because this study included patients with various stages of the disease. For instance, although a change in the length of ISe from 8000 to 7000 μm indicates the same extent of progression as a reduction from 1500 to 500 μm, the implications are quite different.…”

“…W postępowaniu farmakologicznym rozważano suplementację niektórych witamin, takich jak A i E [9,10], kwasu dokozaheksagenowego (docosahexaenoic acid -DHA) [3,10,11,12], luteiny [13,14], kwasu walproinowego [15,16], beta-karotenu [17], a także zastosowanie miejscowego podawania 0,2% winianu brimonidyny [18], wszczepianie wewnątrzgałkowych implantów [19] czy doustne przyjmowanie nilwadypiny [20]. Nadzieję wiąże się także z terapią genową [21,22,23] i transplantacją komórek macierzystych [21,23,24,25,26].…”

“…Niestety wyniki randomizowanych, kontrolowanych badań oceniających zmiany w polu widzenia i ostrości wzroku oraz ERG u pacjentów z RP otrzymujących suplementację witamin A, E i DHA nie wykazały istotnego wpływu na zahamowanie postępów choroby [9,10,11,12]. Berson i wsp.…”

“…Micronutrient supplements (Berson et al, 2004) and gene therapy to introduce trophic factors (McGee Sanftner et al, 2001) or to correct mutated genes (Bainbridge et al, 2008;Maguire et al, 2008) may be helpful in the early stages, but once photoreceptors and RPE cells are lost, only techniques to reconstruct or bypass the damaged retina will restore vision (for review, see Cronin et al, 2007).…”
