The inhibitor of apoptosis protein (IAP) family acts as an inhibitor of apoptosis pathways. The potential prognostic value of the expression of selected IAP family members, XIAP, cIAP-1, cIAP-2 and survivin protein, was evaluated with regard to treatment response and survival of 56 newly diagnosed adult patients with acute myeloid leukemia (AML). The presence of these IAP members influenced the achievement of a complete response (CR). In addition, overall survival (OS) was influenced by low survivin expression in univariate and multivariate analysis (p = 0.014 and p = 0.013, respectively). A strong correlation was observed between members of the IAP family (XIAP and cIAP-1, XIAP and cIAP-2, cIAP-1 and cIAP-2, p < 0.001 for all comparisons), while Smac/DIABLO demonstrated an inverse correlation with XIAP, cIAP-1 and cIAP-2 (p < 0.001 for all comparisons). Further studies should be undertaken to better demonstrate the mode of action of IAP members, as well as their prognostic and therapeutic potentials.

30/30 patients with lower UTI were enrolled in a randomized study to compare ciprofloxacin (250 mg/b.i.d.) and cefalexin (1 g/t.i.d.). In addition, 59 patients with cefalexin-resistant bacterial strains were treated in an open study arm. Ciprofloxacin showed convincingly better clinical and bacteriological efficacy than cefalexin. Both antibiotics were well tolerated. Ciprofloxacin has proved to be superior to cefalexin in the treatment of lower UTI.

IntroductionThe misbalance between a family of inhibitor of apoptosis proteins (IAP), regulated by the nuclear factor kappa B (NF-κB) and their natural antagonist second mitochondrial-derived activator of caspases/direct IAP binding protein with low pI (Smac/DIABLO) are important to biology of acute myeloid leukemia (AML).Material and methodsThe aim of the study was to assess NF-κB and Smac/DIABLO proteins expression in blasts of 109 newly diagnosed AML patients using the multicolor flow cytometry and evaluate their influence on AML patients outcome.ResultsExpression of NF-κB and of Smac/DIABLO proteins were found in 95% and 98% of the patients, respectively. A negative correlation between Smac/DIABLO and NF-κB was observed. Age < 60 years old as well as higher Smac/DIABLO expression were associated with a higher probability of complete response achievement in the multivariate analysis. Longer overall survival (OS) in the univariate and multivariate analyses was influenced by age < 60 years old, a favorable or intermediate-risk karyotype and high Smac/DIABLO expression. Additionally, in the survival analysis of the subgroups, the patients aged < 60 years old, with high Smac/DIABLO expression, lower NF-κB expression and < 50% of bone marrow blasts who were treated with standard treatment had better OS.ConclusionsLower NF-κB and higher Smac/DIABLO expression may influence AML patients outcome.

Of 60 patients who were suffering from bacterial infections, 30 were treated with mezlocillin and 30 with carbenicillin in a randomized study. The patients received the recommended daily doses of 16 g and 30 g, respectively. Clinical efficacy was found in all patients. Mezlocillin eliminated the strains more reliably than carbenicillin. The bacteriological success rate was 27/30 and 16/30, respectively. We should also take into account the fact that the six patients with cholecystitis who were treated with carbenicillin could not be controlled after treatment.
