"Real world" outcome of lenalidomide plus dexamethasone in the setting of recurrent and refractory multiple myeloma: extended follow-up of a retrospective multicenter study by the "rete ematologica pugliese".

This current retrospective multicenter analysis represents, to our knowledge, the first Italian study evaluating the efficacy and toxicity profile of "lenalidomide plus dexamethasone" as salvage therapy in patients with recurrent-refractory MM in the real life contest. Our study included patients who are usually excluded from clinical trials because of unfavorable baseline characteristics. Median OS was significantly longer in patients receiving "lenalidomide plus dexamethasone" for more than 12 months compared with those who had received "lenalidomide plus dexamethasone" for a shorter interval (P<0.0001). Median OS was not affected by best response achieved (P 0.4) and age (P 0.3). Quality of response did not correlate with number of previous lines of therapy (P 0.77) and age. Higher ORRs were recorded in the patients group with relapsed MM compared to those with refractory disease, but this difference was not statistically significant (P 0.38).

Oral iron chelator deferasirox in the treatment of secondary hemochromatosis following bone marrow transplantation in a patient with severe aplastic anemia.

Iron overload sometimes complicates the clinical course of bone marrow transplantation and can cause damage to liver and heart function. A patient with post-transplantation secondary hemochromatosis was treated with deferasirox, which not only normalized ferritin levels, but also reduced hepatic iron to normal values as measured by biosusceptometry with a superconducting quantum interference device. Side effects were minimal. The use of deferasirox to reduce post-transplant iron burden merits evaluation in a larger patient population.

Antibodies to HTLV-III and the lymphadenopathy syndrome in multitransfused beta-thalassemia patients.

Antibodies to HTLV-III have been investigated in 118 multitransfused beta-thalassemia patients. Thirteen patients (11.01%) were found to be positive; 3 of these 13 showed clinical and immunological signs of the lymphadenopathy syndrome. A retrospective study carried out on 65 sera has shown that at least 6 patients were negative 3 years before the present investigation. This is the first extensive study on HTLV-III infection in multitransfused beta-thalassemics. It suggests that these patients are at risk for the acquired immune deficiency syndrome and related diseases.

[Alpha-thalassemia in Puglia. II. Neonatal screening for Bart's hemoglobin]. / L'alfa thalassemia in Puglia. II. Screening neonatale per l'Hb di Bart.

550 blood specimens from the umbilical cord of newborn babies from Apulia have been screened in order to detect Hb Bart's. The electrophoresis of the haemoglobin by Cellogel (Tris Glycine pH 8.6) carried out on the 550 specimens have revealed in 43 variable quantities of Hb Bart's: 34 cases (6,18%) showed non measurable quota, whereas in the other 9 cases (1,63%) Hb Bart's varied from 2,19% to 26%. The haemoglobin biosynthesis "in vitro" of the baby presenting 26% of Hb Bart's has been reported.
