RESUMEN
EXtend and eXjange were prospective, 1-yr, non-interventional, observational, multicentre studies that investigated deferasirox, a once-daily oral iron chelator, in iron-overloaded chelation-naïve and prechelated patients with myelodysplastic syndromes (MDS), respectively, treated in the daily-routine setting of office-based physicians. No inclusion or exclusion criteria or additional monitoring procedures were applied. Deferasirox was administered as recommended in the European Summary of Product Characteristics. Haematological parameters and adverse events (AEs) were collected at two-monthly intervals. Data from 123 chelation-naïve patients with MDS (mean age 70.4 yrs) with median baseline serum ferritin level of 2679 (range 184-16,500) ng/mL, and 44 prechelated patients with MDS (mean age 69.6 yrs) with median baseline serum ferritin level of 2442 (range 521-8565) ng/mL, were assessed. The mean prescribed daily dose of deferasirox at the first visit was 15.7 and 18.7 mg/kg/d, respectively. Treatment with deferasirox produced a significant reduction in median serum ferritin levels in chelation-naïve patients with MDS from 2679 to 2000 ng/mL (P = 0.0002) and a pronounced decrease in prechelated patients with MDS from 2442 to 2077 ng/mL (P = 0.06). The most common drug-related AEs were gastrointestinal, increased serum creatinine levels and rash. These studies demonstrate that deferasirox used in physicians' medical practices is effective in managing iron burden in transfusion-dependent patients with MDS.

The non-nucleoside reverse transcriptase inhibitors (NNRTIs) efavirenz (EFV) and nevirapine (NVP) taken in combination with nucleoside reverse transcriptase inhibitors (NRTIs) have both shown to be just as highly effective as protease inhibitors (PIs) in reducing viral load in patients infected with HIV. Our study compares the performance of these two NNRTIs with each other. This was a non-randomized, prospective, two-arm, multi-centre trial. We evaluated all patients with an EFV- or NVP-containing antiretroviral regimen. The primary endpoint was the difference in success rates defined as a viral load of
