    Hydroxychloroquine toxicity autofluorescence


    Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight.

    Hydroxychloroquine HCQ is efficacious for various diseases1,2, but can produce “bulls-eye” retinopathy that decreases vision even after discontinuance3,4. Retinopathy can be present in 7.5% of patients after 5 or more years of HCQ treatment, increasing to 20% after 20 years2. In 2016, the American Academy of Ophthalmology published new recommendations for the evaluation of HCQ. Fundus Autofluorescence FAF Early hydroxychloroquine toxicity can also be detected on autofluorescence as an increased ring of signal within the parafoveal and extramacular regions, which is indicative of photoreceptor dysfunction and RPE dysfunction. Dec 04, 2014 Hydroxychloroquine HCQ is an anti-malarial medication that has in recent times been utilized as treatment for a variety of autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus, and other inflammatory and dermatologic conditions. 1

    Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use. There are no similar demographic data for CQ, but dose comparisons in older literature suggest using 2.3 mg/kg real weight.

    Glycerol shock or chloroquine? - Transfection and Transduction Hours after transfection reaction has been applied to cells, gently remove media and replace with 10% glycerol or DMSO for 2-3 minutes. Remove and feed with complete media various references. *1 hour before transfection, replace cDMEM with cDMEM + 25 mM chloroquine. Add transfection reaction to this media, and incubate o/n JoVE.

    The antimalarial drugs quinine, chloroquine and mefloquine.
