OBJECTIVE: B cell-depletion therapy based on rituximab is a therapeutic option
for refractory disease in patients with systemic lupus erythematosus (SLE). The
aim of this observational study was to document long-term effects on B cell
function by following serum immunoglobulin levels in patients with SLE treated
with rituximab in routine clinical practice. METHODS: We included 57 consecutive
patients with SLE treated with rituximab and concomitant/sequential
immunosuppressants and measured serum total IgG, IgM, and IgA and IgG anti-dsDNA
antibodies, over a median of 48 months most recent followup. Flow cytometry was
used prospectively to assess B cell phenotypes in 17 of 57 patients. RESULTS:
Twelve patients (21%) had persistent IgM hypogammaglobulinemia (<0.4 gm/liter),
and 4 of 57 (5%) had low IgG (<7 gm/liter) at the most recent followup (range
12-144 months). This was not associated with serious adverse events or high
anti-double-stranded DNA (anti-dsDNA) antibodies (>1,000 IU/ml; normal <50
IU/ml). Factors predictive of low serum IgM included baseline serum IgM ?0.8
gm/liter (receiver operator curve analysis) and subsequent therapy with
mycophenolate mofetil (MMF; odds ratio 6.8, compared with other
immunosuppressants). In patients maintaining normal IgM levels (9 of 17), the
frequency of circulating IgD+CD27+ B cells was significantly higher (P?=?0.05).
At 12 months after rituximab, 7 of 30 SLE patients with baseline anti-dsDNA
?1,000 IU/ml had lost seropositivity. CONCLUSION: Lower baseline serum IgM levels
and sequential therapy with MMF were predictive of IgM hypogammaglobulinemia
after rituximab in SLE, but this was not associated with higher levels of
anti-dsDNA antibodies or an increased risk of infections. This provides useful
directions for clinicians regarding rituximab and sequential immunosuppressive
treatment for patients with SLE.
