Complementary and alternative medicine (CAM) is common in patients with cancer and its use is steadily increasing over time. We performed a multicenter survey in which the use of CAM in 442 Italian patients with chronic lymphocytic leukemia (CLL), the commonest form of leukemia in Western countries, was assessed. Data were collected by means of a face-to-face standardized questionnaire with several items. Mean age was 69 years; 258 patients (58%) were male and 184 (42%) female. Seventy-three patients (16.5%) were found to be CAM users. The most common CAM therapies were green tea, aloe formulations and high dose vitamins. Predictors of CAM use were female gender, younger age, higher education level, internet availability and newspaper reading. The reasons for CAM popularity among these patients are complex. Given the number of patients combining therapy with CAM and its possible drug interactions, doctor interest as well as patient education about CAM should be improved.

Autoimmune hemolytic anemia (AIHA) is a well-known complication of chronic lymphocytic leukemia (CLL). In recent years the anti-CD20 monoclonal antibody rituximab has been used for the therapy of steroid-refractory AIHA and autoimmune thrombocytopenia, either idiopathic or in association with CLL. We report the results of rituximab treatment for 14 patients suffering from CLL-associated AIHA. They developed a direct antiglobulin test positive AIHA at a mean time of 47 months (range 0-135 months) from the diagnosis of CLL. In 3 cases AIHA was diagnosed at the same time as CLL. Only 1 patient had fludarabine-related AIHA. All patients received steroids as first-line treatment. At a mean time of 46 days (range 1-210 days) from the diagnosis of AIHA all patients received rituximab at a dosage of 375 mg/m(2)/weekly for 4 weeks. All patients except 3 (2 died of cardiac failure or sepsis soon after the third cycle and 1 HCV-positive patient experienced a rise in serum amino transferases) completed the scheduled four programmed cycles. First injection side effects of rituximab were minimal. All but 2 patients showed an increase in hemoglobin levels in response to rituximab (mean value 3.6 g/dl; range 0.7-10 g/dl) and a reduction in the absolute lymphocyte count and lymph nodes and spleen volume. Nine patients required packed red cell transfusions before starting rituximab; 5 no longer needed transfusions just after the second cycle and another patient after the fourth cycle. Three patients (22%) were considered to fully respond and 7 (50%) only responded partially. At a mean follow-up of 17 months, 8 patients were still alive, 6 of them transfusion-free. Our results prove that the anti-CD20 monoclonal antibody is an effective and well-tolerated alternative treatment for CLL-associated AIHA.

We report a case of Guillain-Barré Syndrome (GBS) which appeared after mobilization therapy in a patient with B-cell chronic lymphocytic leukemia (B-CLL). After obtaining a partial remission with four cycles of fludarabine at standard dose, the patient underwent to high-dose Cytoxan in order to mobilize CD34+ hematopoietic progenitor cells. During neutropenia the patient experienced fever of unknown origin (FUO) and subsequently developed GBS with normalization of his neurologic condition after 2 months. It is possible that a viral-induced activation of an antigen-specific T and B-cell clone caused a local inflammation and toxicity of Schwann cells with demyelination and axonal damage with a self-limited course.
