    Documentedthataround80-90%of all L. donovani infections did not lead to clinical disease. The ratio ofincident clinical disease to incident seroconversion in these communities was 10 to 1 andrecent seroconverters had a ten timeshigherrisktodevelopdisease in the subsequent 18 months than those who did not sero-convert.

    Identified and defined the subsets of regulatory T cells play a role in pathogenesis of human VL, to identify the cellular source of the elevated IL-10 that is associated with active disease, and to validate IL-10orothersuppressivefactorsas potential targets to enhance the anti-parasitic immune response.

    Identified the HLA DR-DQ region (encodingMHC,classII,DRandDQ) as the majorsusceptibility locus across India and Brazil.

    Three diagnostic tests for VL were evaluated: FD-DAT (freeze-dried direct agglutination test), rK39 dipstick, and KAtex (urine latex antigentest).

    Tissue, blood, and urine samples were collected from clinical suspects,anddiagnostictestswere compared with direct microscopic examination of tissue smears.

    FD-DAT and rK39 demonstrated highaccuracy,withsensitivityover 95% and specificity over 90%.

    500 VL patients were randomly assigned to receive a single 15 mg/kg infusion of ABLE (376 patients)orLAmB(124patients).

    Initial cure rates were 95.9% for ABLE and 100% for LAmB, with clinical improvement similar between both groups (ABLE: 98.9%,LAmB:98.4%).AtDay180,

    definitive cure was achieved in 85.9%ofABLEpatientscompared to 98.4% for LAmB.

    Previous investigations using Leishmania lysate antigen demonstratedthattheimmunoglobulin (Ig) G1 response is a potential indicator of a patient's clinical status after chemotherapy. IgG1 or IgG enzyme- linked immunosorbent assays (ELISAs) with rK39 or lysate antigens and novel IgG1 rK39 rapid diagnostic tests (RDTs) were assessed with Indian VL serum samples from the following clinical groups: paired pre- and postchemotherapy (deemed cured); relapsed;otherinfectiousdiseases;and endemic, healthy controls. With paired pre- and post-treatment samples (n = 37 pairs), ELISAs with rK39- and IgG1- specific conjugates gave a far more discriminative decrease in post- treatment antibody responses when comparedtoIgG(P<.0001).NovelIgG1 rK39RDTsprovidedstrongevidencefor decreased IgG1 responses in patients who had successful treatment (P <

    .0001). Furthermore, both IgG1 rK39 RDTs (n = 38) and ELISAs showed a highly significant difference in test outcomes between cured patients and those who relapsed (n = 23; P < .0001).

Of 23 patients who were available for xenodiagnosis after treatment, one remained infectious to flies by qPCR on the pooled flies, but none remained positivebymicroscopy.Noneofthe184 asymptomatic participants were infectious to sandflies.
