    Hydroxychloroquine diagnostic studies routinely


    One such commonly used medication for dermatologic and rheumatologic inflammatory conditions is hydroxychloroquine (Plaquenil), a chloroquine derivative. It is used to treat many diseases including malaria, rheumatoid arthritis and systemic lupus erythematosus.

    Mechanism of Toxicity. The mechanism of hydroxychloroquine retinal toxicity has yet to be fully elucidated. Studies have shown that the drug affects the metabolism of retinal cells and also binds to melanin in the RPE, which could explain the persistent toxicity after discontinuation of the medication. Hydroxychloroquine is commonly used alongside other disease-modifying drugs including methotrexate – especially for rheumatoid arthritis. However, some drugs can interact with hydroxychloroquine. Indigestion remedies for example, antacids including some over-the-counter preparations can stop hydroxychloroquine being absorbed. While FDA has granted approval for the treatment of discoid lupus97 and small clinical studies have shown positive benefits for porphyria cutanea tarda,98,99 in a large randomized clinical trial of dermatomyositis, HCQ treatment for 24 weeks did not show significant improvements in mouth and eye dryness compared with that in the placebo group.58 The immunological properties of CHQ analogues have also been tested in many bacterial, viral, and parasitic infections such as Q fever, chikungunya.

    It is imperative that patients and physicians are aware of and watch for this drug’s ocular side effects. Retinal toxicity from hydroxychloroquine is rare, but even if the medication is discontinued, vision loss may be irreversible and may continue to progress.

Hydroxychloroquine 6 mg/kg/day, max 400 mg/day is routinely used at the onset of disease in children and adolescents with SLE to reduce symptoms of fatigue, mucocutaneous manifestations, and alopecia, as well as a steroid toxicity–sparing agent. Efficacy of antimalarials in SLE has been demonstrated in clinically stable adults, with removal of the drug, resulting in increased incidence of disease activity.

    Sep 13, 2019 However, hydroxychloroquine is not used to treat severe or complicated malaria. Hydroxychloroquine is used to treat discoid lupus erythematosus DLE or systemic lupus erythematosus SLE or lupus. It is also used to treat acute and chronic rheumatoid arthritis. Hydroxychloroquine is available only with your doctor's prescription. Historically, the introduction of the age-corrected R1R2 ring ratio analysis significantly reduced interindividual variations and increased confidence in the interpretation of mfERG for chloroquine and hydroxychloroquine retinal toxicity. 11 Further studies showed that normalization to Ring 5, which is made up of multiple hexagons as opposed to a single central hexagon Ring 1, could increase the sensitivity of mfERG and reduce reliance on age correction. 12 The R2R5 ring ratio was found. Oct 15, 2012 Hydroxychloroquine HCQ is a 4-aminoquinoline which differs from chloroquine CQ in the addition of a hydroxyl group. Initially used as antimalarials, both drugs have now become mainstays in the management of rheumatic diseases principally systemic lupus erythematosus SLE and rheumatoid arthritis RA.

    The lysosomal inhibitor, chloroquine, increases cell surface. Sep 15, 2013 Chloroquine is a lysosomotropic agent as it is usually prepared as a diprotic weak base pKa 8.5. The unprotonated form of chloroquine preferentially accumulates in lysosomes as it rapidly diffuses across cell/organelle membranes.
