    Streszczenie angielskie: In order to define more accurately the role of multidrug resistance (MDR)-related protein (mrp) gene in chronic lymphocytic leukemia (CLL), we addressed the question of its expression pattern in isolated peripheral blood B lymphocytes in seven healthy donors and 28 patients with CLL, with respect to some laboratory and clinical parameters of the disease. For this purpose, we used a semiquantitative reverse transcriptase polymerase chain reaction (RT-PCR), based on the coamplification of an internal standard not homologous to the DNA target to quantify the mrp transcription level in each studied sample. We report that the level of constitutive mrp gene's expression in peripheral blood lymphocytes is higher in CLL patients than in healthy controls. We found increased mrp gene expression levels in patients with higher white blood cells (WBC) and lymphocytes' counts as well as in more advanced disease stages according to Rai or Binet scale. Finally, mrp gene's expression was higher in patients with progressive CLL, especially in cases refractory to chemotherapy salvage. The results of the present study suggest that expression of mrp gene might be relevant in the pathogenesis of the MDR phenotype in CLL.

    Streszczenie angielskie: Cutaneous presentation of B-cell chronic lymphocytic laukaemia (B-CLL) is uncommon, and the influence of skin changes on B-CLL prognosis is unclear. We report a patient with B-CLL Rai II, with multiple nodular skin infiltrations on the trunk, arms and thighs as well as constitutional symptoms, who was successfully treated with cladribine. The peripheral blood (PB) lymphocytes were CD19, CD20, Cd23 and CD5 positive, which confirmed the diagnosis of B-CLL. Skin biopsy of one of the lesions showed an intense infiltrate composed of small lymphocytes with no epidermotropism. These cells also showed the expression of CD19, CD20, CD23 and CD5 antigens similar to those presented on PB lymphocytes. Polymerase chain reaction performed on bone marrow lymphocytes and a lesional skin biopsy using consensus primers for immunoglobulin heavy-chain genes also showed the same monoclonal population of B lymphocytes both in the bone marrow and in the skin. The patient received four courses of cladribine 0ú12 mg/kg**-1 daily as a 2-h infusion for five consecutive days. The courses were repeated at monthly intervals. The lymphocytosis gradually decreased and the PB count normalized after three courses. At the same time, a significant decrease in the cutaneous symptoms was observed. The patient became free of skin tumours after the fourth course of cladribine; only slight discoloration at the previous sites of cutaneous infiltration remained. There was no relapse of laukaemia cutis during a further 7 months of observation.
