5 CONCLUSION
In conclusion, our study provides evidence of a causal relationship between HHV-6 infection and CLA. This finding helps us understand the etiology of CLA and emphasizes the role of HHV6 in CLA in future studies. Further research is required to understand the impact of HHV-6 primary infection versus reactivation on the risk of CLA. We recommend testing for HHV-6 infection in patients with unexplainable Cutaneous leukocytoclastic angiitis. The relationship between herpesviruses and other forms of angiitis warrants further investigation.
