Abstract

Definitive diagnosis of kala-azar requires demonstration of parasites by diagnostic protocols based on invasive organ aspirations. We evaluated in the present study the diagnostic utility of an immunochromatographic test (ICT) for detection of anti- rK-39 antibodies for the non-invasive diagnosis of kala-azar and post kala-azar dermal leishmaniasis (PKDL) at a tertiary care centre of north India. The study was conducted in the Department of Microbiology, All India Institute of Medical Sciences, New Delhi, from July 2003 to October 2004. Of the 120 samples tested, 57 were found to be positive by ICT; of which, 51 were diagnosed as kala-azar and 6 as PKDL. The controls included individuals from endemic (50) and non endemic (19) areas with malignancies, haemolytic disorders, chronic liver diseases, hypersplenism, portal hypertension, metabolic disorders and sarcoidosis. In addition, 47 sera from confirmed cases of tuberculosis, malaria, typhoid, filariasis, leptospirosis, histoplasmosis, toxoplasmosis, invasive aspergillosis, amoebic liver abscess, AIDS, leprosy, cryptococcosis, strongyloidiasis, cyclosporosis, patients having collagen vascular diseases and hypergammaglobulinaemia were also tested to check the specificity of the t...Continue Reading

Aspergillosis

Aspergillosis is the name given to a wide variety of diseases caused by infection by fungi of the genus Aspergillus. Aspergillosis occurs in chronic or acute forms which are clinically very distinct. Most cases of acute aspergillosis occur in patients with severely compromised immune systems. Chronic colonization or infection can cause complications in people with underlying respiratory illnesses. Discover the latest research on aspergillosis here.

Antiparasitics

Antiparasitics are medications which are indicated for the treatment of parasitic diseases. Discover the latest research on antiparasitics here.
