[First experience with the application of rituximab for the treatment of patients with Sjogren's syndrome and disease].

Efficiency and tolerability of rituximab therapy were assessed in 13 patients with Sjogren's syndrome and disease (10) (SLE-1, RA-2). Nine patients (SD-8, PA-1) presented with lymphomas and 4 with systemic manifestations of the disease. Complete and partial remission of lymphoma was achieved in 7 (78%) and 2 (22%) patients respectively. Beneficial effect of therapy on systemic manifestations of the disease was recorded in 3 (75%) of the 4 cases and only 1 patient had cryoglubulinemic glomerulonephritis resistant to rutiximab. Subjective improvement of glandular manifestations was reported by 12 (92%) patients. Objective improvement of salivation and lacrimation was documented in 7 (54%) and 6 (48%) patients who had residual secretion before therapy. Positive outcome of therapy in 12 patients was associated with complete depletion of CD20+ lymphocytes in peripheral blood. These cells were found in a patient who died despite the treatment. Rutiximab significantly decreased medians of ESR, IgG, IgA, IgM, gamma-globulin, and RF levels (p = 0.05-0.002). In 8 patients, therapy resulted in the disappearance of blood cryoglobulins. Intravenous premedication with 500 mg methylprednisolone prevented side effects of rutiximab. The study showed high efficiency and good tolerability of rituximab in combination with pulsed therapy with alkylating cytostatics and courses of polychemotherapy for the treatment of lymphoma and cryoglobuliemic vasculitis in patients with Sjorgen's syndrome and disease. Combination of rutiximab and pulsed therapy was more efficient than rutiximab monotherpy in patients with grade I-IIE MALT-type lymphomas. Rutiximab decreased systemic and glandular manifestations of Sjogren's disease and syndrome in 75 and 48-54% of the patients respectively.
