Background: around 1% of the Peruvian population lives with HTLV-1 infection. Of those infected, 3-5% could develop adult T-cell leukemia/lymphoma (ATLL). Strongyloides stercoralis co-infection has been associated with earlier ATLL onset. HTLV-1 infected CD4+ T cells express the surface marker CADM1. It is hypothesized that downregulation of CD7 is an indicator of ATLL progression in infected cells. Objective: to characterize, based on flow cytometry analysis, the proportion of CD4+ T cells that are CADM1+ and CD7- at diagnosis and at 2 and 4 weeks after initial antihelminth treatment in patients coinfected with HTLV-1 and Strongyloides stercoralis. Materials and methods: descriptive study using a secondary database. Flow cytometry results were analyzed using FlowJo (v10). For statistical analysis Stata (v17) was used. Results: the median of the proportion of CADM1+/CD7- CD4 T cells was 2.24% at the first visit and 4.40% at the last visit. No significant variation was observed between them. There was a trend towards stabilization in the proportion of CADM1+/CD7- CD4 T cells between the second and third visits (median 0,5%, p = 0,26). Conclusions: in this pilot study we observed a trend towards a reduction in the CADM1+/CD7- CD4 T cell population after starting antiparasitic treatment in patients coinfected with HTLV-1 and nonsevere strongyloidiasis. Even though further evaluation is needed in patients with severe strongyloidiasis, this finding suggests that there is no immediate monoclonal expansion that could increase the risk of ATLL.
