Immunological disorders leading to infectiousarthritis: case report
A 28-year-old man developed hypogammaglobulinaemiaand B-cell aplasia, with subsequent infectious arthritis due toUreaplasma urealyticum, after receiving antineoplastics forlarge B-cell lymphoma. [Dosages and duration of treatment notstated for all drugs except rituximab.]
The man was treated with eight cycles ofcyclophosphamide, doxorubicin, vincristine and prednisone,plus radiotherapy. After pulmonary relapse 3 months later, hereceived two cycles of etoposide, methylprednisolone,cytarabine and cisplatin and underwent surgical tumourdebulking. He received rituximab 375 mg/m2 postoperativelyin four weekly doses. One week after the last rituximab dose,he received further chemotherapy: etoposide, carmustine,cytarabine and melphalan, followed 1 month later by reducedintensity haematopoietic stem cell transplantation (HSCT)using fludarabine and radiation. Despite receivingmethotrexate and ciclosporin A for prophylaxis, he developedgraft versus host disease (GVHD), which was treated withcorticosteroids. Possible pulmonary aspergillosis was treatedwith voriconazole, and cytomegalovirus (CMV) infection wastreated with ganciclovir. One hundred days after HSCT hedeveloped extensive and moderately severe GVHD. At8 months post-transplantation, he presented with joint pain,left elbow tender swelling and redness. This spread to otherjoints and was accompanied by generalised erythema. He wasinitiated on piperazillin/tazobactam. There was noimprovement 5 days later and he was noted to havelymphopenia with complete B-cell aplasia andagammaglobulinaemia. Treatment was changed todoxycycline and IV immunoglobulin (IVIG). Polymerase chainreaction testing of joint fluid was positive for U. urealyticum,and septic arthritis due to U. urealyticum was diagnosed. Heexperienced a reactivation of his CMV, RSV-pneumonitis andacute renal failure necessitating haemodialysis.
His infections were treated and he recovered from thearthritis and other complications. He remained in completeremission 4.5 years post-transplant. Lack of immunoglobulinproduction persisted, and IVIG was continued.
Author comment: "[T]he combination of multiplelymphocytotoxic therapies. . .(intensive chemotherapy incombination with rituximab, intensive conditioning regimenincluding fludarabine and total body irradiation, allogeneicHSCT, GVHD and its treatment with corticosteroids) led toimpaired immune reconstitution post transplant, whichresulted in complete and long-lasting B-cell aplasia andagammaglobulinemia."Arber C, et al. Septic polyarthritis with Ureaplasma urealyticum in a patient withprolonged agammaglobulinemia and B-cell aplasia after allogeneic HSCT andrituximab pretreatment.
