Beta 2-microglobulin (beta 2m) is a small protein that forms the light chain of the class I major histocompatibility molecule and is also present in soluble form in serum and cerebrospinal fluid (CSF). Measles is associated with immune activation and evidence of immunologic abnormalities that persist for several weeks. To assess further the immunologic changes occurring during measles, beta 2m was measured in plasma and CSF. beta 2m became elevated during measles before the onset of the rash and was highest during the rash. Elevations persisted for several weeks and correlated well with levels of soluble interleukin-2 receptor and neopterin and less well with soluble CD8. CSF beta 2m was elevated in postmeasles encephalomyelitis. Plasma levels of beta 2m did not correlate with spontaneous proliferation of peripheral blood mononuclear cells (PBMC) or with in vitro production of beta 2m by cultured PBMC. The data suggest that increases in beta 2m in measles correlate better with cytokine production than with cell proliferation.

To study T cell and macrophage activity during measles, levels of interferon-gamma (IFN-gamma) and neopterin in plasma and cerebrospinal fluid (CSF) were measured. Plasma levels of IFN-gamma were elevated in measles (1.17 +/- 0.27) compared with healthy adults (0.13 +/- 0.06, P less than .05) and children (0.14 +/- 0.06, P less than .01). Plasma levels of neopterin were elevated in measles (32.5 +/- 2.7) compared with healthy adults (5.3 +/- 2.9, P less than .0001), healthy children (12.1 +/- 4.0, P less than .001), and children with other infectious diseases (20.6 +/- 4.0, P less than .02). IFN-gamma was increased in measles primarily during rash; neopterin remained elevated for several weeks. Levels of neopterin showed a significant positive correlation with plasma levels of soluble interleukin-2 receptor and soluble CD8, two other parameters of T cell activation. Children with measles complicated by pneumonia had higher levels of neopterin in serum than those with uncomplicated disease. Children with measles complicated by autoimmune encephalomyelitis had higher levels of neopterin in CSF than those with noninflammatory neurologic disease but lower than those with central nervous system infections. Thus, IFN-gamma seems to be produced in vivo during acute measles virus infection; deficiency of this lymphokine does not appear to correlate with increased susceptibility to secondary infections.
