Efficacy of Diacerein on Ocular Surface Disease in Degenerative Arthritis Patients

Dry eyes is multi-factorial disease which inflammation play etiological role. Diacerein is drug which has anti-inflammatory effect by antagonist Interleukin-1, decrease Interleukin-1 receptor, increase Interleukin-1 Receptor antagonist. This observational study enrolled participants who going to take diacerein for osteoarthritis, measure corneal staining score, Ocular surface disease index score, Tear Osmolarity, Tear break up time, Schirmer 1 test, Interleukin-1 Receptor antagonist, Interleukin-1 alpha, Interleukin-1 beta level in tear at the time of enrollment and after 2 months.

Treatment and study plan

Diacerein

Drug

Diacerein prescribing by orthopedist. Dry eye sign and symptom was asses before start diacerein and after 2 months.

Primary outcomes

  1. Corneal staining score change from baseline at 2 months

    Time frame: At the time of enrollment and 2 months

    Stain Cornea with Fluorescine, count and score staining at the cornea according to National eye institute : score 0-15 (0=no staining)

Secondary outcomes

  1. Ocular surface disease index score

    Time frame: At the time of enrollment and 2 months

    Ocular Surface Disease Index : 0-100 (0=no any symptom)

  2. Tear Osmolarity

    Time frame: At the time of enrollment and 2 months

    Use Tearlab to measure tear osmolarity

  3. Tear break up time

    Time frame: At the time of enrollment and 2 months

    Stain Cornea with Fluorescine, wait until tear film break, record time that tear break

  4. Schirmer 1 test

    Time frame: At the time of enrollment and 2 months

    place Schirmer strip at the fornix without anesthesia, wait for 5 min, record tear distance

  5. Interleukin-1 receptor antagonist, Interleukin-1 alpha, Interleukin-1 beta level in tear

    Time frame: At the time of enrollment and 2 months

    Extract tear from Schirmer strip and use Bioplex for cytokine measurement of Interleukin-1 receptor antagonist(picogram/ml), Interleukin-1 alpha(picogram/ml), Interleukin-1 beta(picogram/ml)
