Most importantly, it will be very

Aim was to evaluate if IFN-gamma boosts

30-day Sb alone.
Six-month cure rates were similar

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). There

Two treatments for VL were compared:oralmiltefosine((50or 100 mg daily for 28 days, 299 patients).) and intravenous amphotericin B (1 mg/kg every other day for 15 doses, 99 patients). Initialcureratewas100%inboth groups. Six-monthcurerateswere94%for miltefosine and 97% for amphotericin B. Miltefosinehadmildsideeffects (vomitingin38%anddiarrheain 20% of patients).

Paromomycin was found noninferior to amphotericin B for treating VL, with cure rates of 94.6%forparomomycinand98.8% for amphotericin B. Mortalitywaslessthan1%inboth groups. Adverse events were more frequent with paromomycin, includinginjection-sitepain(55%), transient liver enzyme elevation (6%), and reversible ototoxicity (2%). Amphotericin B was associated with nephrotoxicity (4%), fevers (57%),rigors(24%),andvomiting (10%). Paromomycin is a viable alternative to amphotericin B for visceral leishmaniasis treatment in India.PMID:17582067 |

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). There strong evidence for the use of IgG1inmonitoringtreatmentoutcomes inVL,andthefirstuseofanIgG1-based RDT using the rK39 antigen for the discrimination of post-treatment cure versusrelapseinVL.SuchanRDTmay |
