Abstract

Rituximab is an anti-CD20 monoclonal antibody that has demonstrated efficacy in patients with indolent and aggressive forms of non-Hodgkin&#8217;s lymphoma and has become part of the standard therapy for patients with B-cell malignancies. The study was designed to examine if rituximab increases the risk to develop non-neutropenic infection (NNI). Medical records of 202 patients diagnosed as follicular lymphoma or small lymphocytic lymphoma were reviewed. Negative binomial regression was used to estimate relative risk (RR) of NNI. Rituximab (n= 41) and non-rituximab (n= 161) groups had a total of 31.636 and 195.691 reviewed patient days, and recorded a total of 67 and 154 infections, respectively. Negative binomial regression analysis revealed significant effects for the treatment (rituximab vs. non-rituximab) and age (p< 0.01). The RRs of viral and bacterial NNI for rituximab group compared to nonrituximab group were 3.33 and 2.60, respectively; while the RRs for one year increment of age were 1.03 and 1.04, respectively. The time-to-first viral and bacterial NNI for rituximab group were significantly faster than non-rituximab group. Rituximab may increase the risk of NNI in patients with follicular lymphoma or small lymphocytic lymphoma.

Özet

Rituximab bir anti-CD20 antikorudur ve indolant ve agresif Hodgkin dışı lenfomada etkinliği gösterilmiş ve B-hücreli lenfomaların standart tedavisi haline gelmiştir. Bu çalışma rituximab’ın nötropenik olmayan enfeksiyonları artırıp artırmadığını test etmek üzere planlandı. Foliküler lenfoma veya küçük lenfoısitik lenfolmalı 202 hastanın hastane kayıtları incelendi. Risk tahmini için negatif binomial regresyon analizi kullanıldı. Rituximab (n= 41) ve rituximabsız (n= 161) gruplarda total olarak 31.636 ve 195.691 hasta/gün değerlendirildi ve toplam 67’ye karşın 154 enfeksiyon saptandı. Negatif binomial regresyon analizde tedavi ve yaş önemli faktörler olarak bulundular (p< 0.01). Viral ve bakterial non-nötropenik enfeksiyonların relatif riskleri rituximab grubunda rituximab almayan gruba göre sırasıyla 3.33 ve 2.60 olarak saptandı. her bir yıl yaş artışında relatif riski sırasıyla 1.3 ve 1.04 olarak saptandı. İlk viral ve bakterial non-nötropenik enfeksiyon gelişmesi, rituximab grubunda rituximabsız gruba göre belirgin olarak daha hızlı idi. Sonuç olarak, rituximab, foliküler veya küçük lenfositik lenfomalı hastalarda non-nötropenik enfeksiyon riskini artırmaktadır.
