The relationship between strongyloidiasis and HTLV-I was investigated in Okinawa, an area where both conditions are endemic. Thirty-six patients with strongyloidiasis were seropositive for HTLV-I and suffered from several related clinical complications. Fourteen of these patients (39%) were shown to have monoclonal integration of HTLV-I proviral DNA in their blood lymphocytes, a condition designated as "smouldering" adult T-cell leukaemia (ATL). Monoclonal integration of proviral DNA correlated with an increased CD4/CD8 ratio and the presence of abnormal lymphocytes in the peripheral blood, and with a trend for greater severity of the parasitic infection. Although the immunodeficiency caused by HTLV-I could predispose to hyperinfestation by Strongyloides, it is also possible that both the parasitic and the retroviral infestations are important co-factors leading to the development of ATL.
