Efficacy and comparison of antimalarials in cutaneous lupus erythematosus subtypes: a systematic review and meta-analysis

Summary

Background

The antimalarials (AMs) hydroxychloroquine (HCQ) or chloroquine (CQ) have demonstrated variable cutaneous response rates in Cutaneous Lupus Erythematosus (CLE). Objectives: We sought to assess the global cutaneous response rate to HCQ and CQ, with respect to CLE subtypes, based on previously published studies.

Methods

We performed a systematic review and meta-analysis of studies published in MEDLINE, Embase, Cochrane library between 1965 and December 2015. The proportions of responders to AMs according to CLE subtypes were extracted from individual studies and pooled using random-effects or fixed models. The odds ratio (OR) was used as the measure of association to compare the response rates between CLE subtypes and AMs agents.

Results

Among 1990 lines of treatment with AMs from 31 included studies, the overall response rate to AMs was 63% (95% CI: 55-70) with important statistical heterogeneity across included studies. HCQ had a higher overall efficacy than CQ but this was non-significant (OR: 1.48 [95%CI: 0.98-2.23]). The response rate to AMs was different between CLE subtypes ranging from 31% (95% CI: 20-44) for chilblain lupus to 91% (95% CI: 87-93) for acute CLE and was significantly higher for acute CLE than for subacute CLE and intermittent CLE. In case of failure of a monotherapy with AM, the combinations of Quinacrine with HCQ or CQ seemed effective whereas too little data were available to assess the efficacy of the switch to another AM agent.

Conclusions

Wide discrepancies in cutaneous response to AMs are observed between CLE subtypes. A specific therapeutic approach considering CLE subtypes may improve CLE management.
