HCQS advantageous in children with proliferative lupus nephritis
A study published in the European Journal of Pediatrics has mentioned that HCQ improved the disease and LN activity in children with proliferative LN. The study also documented side effects like skin hyperpigmentation and mild retinal changes following HCQ usage.
It is already known that Hydroxychloroquine (HCQ) is an antimalarial agent. It manages mucocutaneous, musculoskeletal, and constitutional manifestations of systemic lupus erythematosus (SLE). There is a lack of data elucidating its side effects in children with a history of proliferative lupus nephritis (LN).
Considering this background, a study was conducted on 60 children with a history of proliferative LN classes III and IV treated with steroids and mycophenolate (MMF) regimens.
The study points could be summarised as follows:
- The study had two groups: the HCQ and the placebo groups.
- The HCQ group had 30 patients, and the placebo also had 30 patients.
- They were evaluated initially at 6- and a 12-month follow-up by mucocutaneous, ophthalmological examination.
- During the follow-up period, investigations were carried out on BUN, creatinine, 24 h proteinuria, triglycerides (TG), cholesterol, Antids-DNA, C3, and C4.
- SLE disease activity index (SLEDAI-2 k) was used.
- In the HCQ group, after 12 months, there was a significant decrease in Triglycerides, cholesterol, 24 h proteinuria, Antids-DNA, and SLEDAI score.
- The cumulative probabilities of developing primary end-points (LN partial and complete remission) were 40% and 60% in the HCQ group versus 53.3% and 36.7% in the placebo after 12 months.
- After 12 months, the HCQ group experienced mucocutaneous alopecia (3.3%), hyperpigmentation (10%), and ophthalmological mild retinal changes (6.7%), but they did not differ significantly from the placebo group.
