L. loa filariasis was diagnosed based on anamnestic data (i.e., area of origin: Cameroon), clinical (i.e., presence of parasite in the eye, pruritus) and paraclinical signs (i.e., eosinophilia and hyper-IgE), and parasitological test confirming the presence of microfilariae (MF) in two blood samples collected in the morning of two different days (at 8:00 am and 11 am, respectively) showing a different parasitic load of 144 MF/mL and 460 MF/mL, respectively. This evidence concerns the gene IGHE and Increased total eosinophil count.
