title: Influence of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone on serologic parameters and clinical course in lymphoma patients with autoimmune diseases.
abstract: BACKGROUND
  As patients with B-cell lymphomas suffering from an underlying autoimmune condition undergoing therapy with the CD20 antibody rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) offer the unique possibility of monitoring effects of therapy on various rheumatologic parameters, we have evaluated serologic autoimmune markers and the clinical outcome of patients with autoimmune diseases (ADs) who received lymphoma treatment with R-CHOP during the course of their disease.
  
  
  METHODS
  We have retrospectively analysed 13 patients with non-Hodgkin's lymphoma who concurrently suffered from ADs and were treated with the R-CHOP regimen. Subjective parameters along with rheumatoid factor (RF) and antinuclear antibodies (ANA) were serially measured.
  
  
  RESULTS
  The median levels of RF were 901 IU/ml [inter-quartile-range (IQR) 189-2520] before and 75 IU/ml (IQR 45-644) after therapy (P = 0.028). The median levels of ANA were 800 (IQR 140-2560) before and 100 (40-1280) after therapy (P = 0.027). Ten (77%) patients showed clinical improvement of their autoimmune symptoms, two (15%) reported no difference and one (7%) patient with rheumatoid arthritis-related worsening symptoms during therapy with R-CHOP. The autoimmune-related symptoms recurred after a median time of 7 weeks (IQR 6-8) in seven patients. In terms of lymphoma response, 11 patients achieved a complete remission and two a partial remission.
  
  
  CONCLUSIONS
  This analysis indicates that R-CHOP given for lymphoma treatment is also effective for therapy of concurrent rheumatoid diseases. Both rheumatoid parameters as well as clinical symptoms showed a significant decrease during treatment with this immunochemotherapy. The effects on the rheumatic diseases, however, seem to be of limited duration.
