Why do this research?

Systemic lupus erythematosus and rheumatoid arthritis are diseases of the immune system that affect many parts of the body (e.g., joints, heart, eyes, skin), and can result in other medical complications and untimely death.

A drug called hydroxychloroquine (HCQ) is commonly used to treat systemic lupus erythematosus and rheumatoid arthritis. Existing studies have highlighted benefits of HCQ, including less severe disease, fewer complications (e.g., blood clots, problems with pregnancy or kidneys), and longer life. However, stopping HCQ can lead to episodes of more severe disease including death. Although HCQ is typically safe, inexpensive and easy to take, a serious long-term side-effect is eye damage that could cause vision loss.

Given the benefits and common use of HCQ, it is critical that the real risk be determined and findings shared with doctors and patients so that patients receive the best and safest care, and the health care system can use its dollars wisely.

What will be done?

Using the administrative health data, we will identify and study all patients in BC with SLE and RA who have been on hydroxychloroquine (HCQ) for at least 5 years and follow them for 5 years to determine the ‘real risk’ of eye damage using state-of-the-art eye testing equipment for annual examinations.

The overall goal of this study is to assess eye damage in systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) patients who use hydroxychloroquine (HCQ), state-of-the-art eye testing equipment.

Who is involved?

The research team consist of researchers, rheumatologists, ophthalmologists and family physicians who are committed to deliver safe and appropriate care to the population.
