| Abstract | Antibodies against cytoplasmic antigens of neutrophils, producing perinuclear (p-ANCA) as well as cytoplasmic staining with central accentuation (c-ANCA), have been described in non-HIV-infected patients with specific pathology such as glomerulonephritis and vasculitis. Here, we report on a patient with a vasculitis-like syndrome and a positive ANCA-test who appeared to be infected by HIV. Further analysis revealed that ANCA, p-ANCA as well as c-ANCA without central accentuation can be demonstrated in the serum of HIV+ individuals. In a cross-sectional study on individuals in different stages of HIV infection, we found that the occurrence of ANCA was limited to the symptomatic stages of HIV infection: p-ANCA was found in one out of 10 ARC patients and in two out of 11 AIDS patients with malignancies (AIDS-MAL), but not in AIDS patients with opportunistic infections (AIDS-OI). c-ANCA was found in four of the ARC patients, in two of the 14 AIDS-OI patients and in two AIDS-MAL patients. The presence of ANCA was not related to the degree of hypergammaglobulinaemia nor to specific symptomatology. ANCA containing sera from HIV+ individuals did not react with HEp2 cells nor with cytoplasmic antigens of lymphocytes, natural killer (NK) cells or eosinophils. Five out of the 11 (two p-ANCA and three c-ANCA) sera reacted weakly with cytoplasmic antigens of monocytes. All sera reacted with karyoplasts but not with cytoplasts prepared from neutrophils. These results suggest that HIV-ANCA might be directed against myeloid cell-specific granule constituents. However, sandwich-ELISAs with MoAbs against granule antigens that are frequently the target antigens of ANCA in HIV- individuals were negative. Also immunoprecipitation and immunoblotting, using lysates of neutrophil granules, did not allow further identification of the target antigens of HIV-ANCA. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
