Anti-C1q antibodies have been found in many different systemic autoimmune diseases, they are strongly linked to immune complex disorder most prominently SLE and severe rheumatoid arthritis and have been suggested to be closely associated with lupus nephritis (LN). Generally anti-dsDNA antibodies have been acknowledged as an important tool in the diagnosis of SLE, however their predictive value as to the activity of the disease remains controversial, on the contrary anti-C1q antibodies appear to have a clear-cut relationship with renal complications of SLE not only have they been shown to play a pathogenic role in the development of lupus nephritis but also their serum levels correlate with the presence of active proliferation lupus nephritis.The aim of the study was to further investigate association between serum titer of anti-C1q antibody and disease manifestation of SLE, significant association were found between increased serum titer of anti-C1q antibody and nephritis with subsequent loss of kidney function . Methodology: the study was carried out in three different groups: healthy group, rheumatoid arthritis group and lupus nephritis group. All groups were subjected to determination of anti-C1q antibody, blood urea nitrogen (BUN) and serum creatinine UR - http://172.23.153.220/th.pdf ER -
