1. Field of the Invention
This invention relates generally to a method of diagnosing leishmaniasis in a subject suspected of being infected with the parasitic protozoa Leishmania. In particular, the invention relates to enzyme-linked immunosorbent assays (ELISAs) for the detection of Leishmania parasite circulating antigens and Leishmania-specific antibodies in host samples.
2. Description of the Related Art
Leishmaniasis is a serious and sometimes fatal disease estimated by the World Health Organization (WHO) to affect approximately 12 million people in 88 countries. Recent epidemics of leishmaniasis have occurred in the Africa, the Indian subcontinent and Brazil. In addition to the concerns regarding significant morbidity and mortality caused by leishmaniasis in endemic areas, the increase in global travel concomitant with the increased incidence of the disease in HIV-infected and intravenous drug-user populations is a cause for concern in non-endemic areas more recently.
Unfortunately, current acceptable diagnostic practices lack the means for efficiently and accurately identifying those infected or exposed to the disease-causing parasite as explained in Martin, S. et al. (1998) Military Medicine 163(23):801-807. As a result, the prevention of leishmanial epidemics is greatly hindered and patient management is difficult. Additionally, there is an imminent threat of a developing population of people co-infected with HIV and Leishmania. To date, there are no antigen-detection type diagnostic tests available for Leishmaniasis. In view of this, antigen-detection assays are desperately needed for diagnosis, patient management and epidemiological studies.
Recombinant kinesin protein, rK39, is one of the few antigens that has been used in the development of antibody-detection immunoassays for active visceral leishmaniasis (VL). However, assays of this antigen and others fail to consistently detect antibodies in other clinical syndromes associated with a predominately T-cell and muted B-cell response. Moreover, antibody-detection assays have an inherent limitation—dependence on the immune response of the host to the parasite antigen. For example, in an immunocompromised host, the infection may not produce proportional antibody production and thereby escape detection.
Generally, the serological tests for diagnosing VL are highly sensitive (>90%). See Senaldi, G., et al., (1996) J. Immunol. Methods 193:9-5. These serological tests, however, pose problems of non-specificity resulting in false positive results from reference samples of other infectious diseases and subclinical leishmanial infections. Modifications of the antigens used for direct agglutination test (DAT) and for ELISA are reported to be markedly successful in eliminating false-positive results. See Zijlstra, E. E., et al., (1997) Trans. R. Soc. Trop. Med. Hyg. 91:671-673 and Badaro, R., et al., (1996) J. Inf. Dis. 173:758-761. Unfortunately, serological tests are rarely performed to diagnose cutaneous leishmaniasis because the sensitivities and specificities are disappointingly poor for that clinical manifestation. See Sanchez, J. L., et al., (1992) Am. J. Trop. Med. Hyg. 47:47-54; Garcia-Miss, M. R., et al., (1990) Trans. R. Soc. Trop. Med. Hg. 84:356-358.
The antigens used in immunoassays for the detection of leishmaniasis are traditionally derived from promastigotes cultivated in vitro, or from recombinant proteins. See Badaro et al. (1996); Choudhary, S., et al., (1992) J. Comm. Dis. 24:32-36; Badaro, R., et al., (1986) Am. J. Trop. Med. Hyg. 35:72-78; Choudhary, A., et al., (1990) Trans. R. Soc. Trop. Med. Hyg. 84:363-366; and Reed, S. G., et al., (1990) Am. J. Trop. Med. Hyg. 43:632-639. The promastigotes release metabolic products into the culture medium to produce conditioned medium. These metabolic products are immunogenic to the host. See Schnur, L. F., et al., (1972) Isrl. J. Med. Sci. 8:932-942; Sergeiev, V. P., et al., (1969) Med. Parasitol. 38:208-212; El-On, J., et al., (1979) Exper. Parasitol. 47:254-269; and Bray, R. S., et al., (1966) Trans. R. Soc. Trop. Med. -Hyg. 60:605-609.
The prior art assays are based on these metabolic products found in the in vitro culture medium. Thus, the presence of complex proteins or serum components required for growth of the parasites in culture pose several problems in the prior art assays. For example, the amount of manipulation needed to purify the targeted antigens from the metabolic products can affect the native composition of certain components necessary for a highly sensitive assay. Furthermore, insufficient purification techniques may create problems with specificity as common proteins remain in the antigen preparations, which cause non-specific reactions. Generally, the prior art assays are limited in scope to one species complex or clinical manifestation and have never demonstrated combined sensitivity and specificity of more than 90%.
Thus, a need exists for highly sensitive and highly specific assays for detecting, measuring, or diagnosing exposure to Leishmania.
