Question: Question: Is the risk of infections in hematologic patients treated with rituximab influenced by cumulative rituximab dosage - a single center experience?
Answer: Rituximab in induction treatment, either as monotherapy or combined with chemotherapy by itself does not increase the incidence or change the spectrum of infections in hematologic patients. However the possible influence of higher dosages of concomitant steroid medication on frequency of infections suggests that a heightened awareness of the potential for infectious complications should be applied to patients receiving higher doses of glucocorticoids in combination with other therapeutic regimens.

Answer:
no
