BACKGROUND AND AIM: Compared to healthy subjects there is a higher
incidence of monoclonal immunoglobulins (= paraproteins = PP) in
patients infected with the human immunodeficiency virus (HIV).
High-grade B-cell non-Hodgkin's lymphomas (NHL) are the second most
common neoplasms in these patients. Our aim was to determine whether
paraproteins would be of diagnostic significance regarding an underlying
or developing NHL. PATIENTS AND METHODS: The sera of 202 HIV-positive
patients were tested for the presence of monoclonal or oligoclonal bands
by using high-resolution-electrophoresis (HRE) and immunofixation (IFX).
We also examined immunoglobulin concentrations, leucocyte count,
lymphocyte count, CD4 lymphocyte count and CD4/CD8-ratio and collected
clinical data. RESULTS: Paraproteins were detected in 26 (12.8%) of the
patients. 84.6% of PP were IgG, in 80.7% associated with a kappa light
chain. Patients with monoclonal or oligoclonal bands developed NHL
significantly more often compared to those without PP (16.7% and 2.8%,
respectively (p < 0.05%)). The CD4 count was significantly higher in
patients with PP. There was no difference in levels of immunoglobulins,
leucocyte count, lymphocyte count and CD4/CD8-ratio. The prevalence of
PP was equally distributed in patients at different CDC-stages of
HIV-infection. Common acute systemic infections like pneumocystis
carinii pneumonia (PCP), toxoplasmosis, mycobacteriosis or
cytomegalovirus (CMV) infection were not associated with paraproteins.
CONCLUSION: We conclude that paraproteins could indicate the presence of
a non-Hodgkin's-lymphoma.
