RESUMEN

Adverse drug reactions (ADRs) reduce patients' quality of life, increase mortality and morbidity, and have a negative economic impact on healthcare systems. Nevertheless, the importance of ADR reporting is often underestimated. The project "FarmaREL" has been developed to monitor and evaluate ADRs in haematological patients and to increase pharmacovigilance culture among haematology specialists. In 13 haematology units, based in Lombardy, Italy, a dedicated specialist with the task of encouraging ADRs reporting and sensitizing healthcare professionals to pharmacovigilance has been assigned. The ADRs occurring in haematological patients were collected electronically and then analysed with multiple logistic regression. Between January 2009 and December 2011, 887 reports were collected. The number of ADRs was higher in older adults (528; 59%), in male (490; 55%), and in non-Hodgkin lymphoma patients (343; 39%). Most reactions were severe (45% required or prolonged hospitalization), but in most cases, they were fully resolved at the time of reporting. According to Schumock and Thornton criteria, a percentage of ADRs as high as 7% was found to be preventable versus 2% according to reporter opinion. Patients' haematological diagnosis, not age or gender, resulted to be the variable that most influenced ADR, in particular severity and outcome. The employment of personnel specifically dedicated to pharmacovigilance is a successful strategy to improve the number and quality of ADR reports. "FarmaREL", the first programme of active pharmacovigilance in oncohaematologic patients, significantly contributed to reach the WHO "Gold Standard" for pharmacovigilance in Lombardy, Italy.

RESUMEN

Adult onset hemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory syndrome, which can develop as a complication of many disorders. Early diagnosis is essential in order to avoid a fatal outcome. To confirm the diagnosis of acquired HLH made in a single institution series of adult patients with HLH-04 criteria, we applied the HScore and evaluated prognostic factors associated with clinical outcome. The median age of 35 patients was 54 (range 17-81), M/F ratio was 20/15. In 26/35 (74.3%) patients, an underlying haematological disease was present (2 Multicentric Castleman Disease, 10 B-cell Non-Hodgkin Lymphoma [NHL] and 14 T/NK-cell NHL); an autoimmune disorder was observed in four (11.4%) patients (one Still Disease, one undifferentiated connective tissue disease and two haemolytic anaemia); in five (14.3%), no underlying disease was identified. A concomitant infection by EBV was observed in 10 patients (28.6%), CMV in 8 (22.9%), HHV8 in 6 (17.1%) and HIV in 1 (2.9%). Hyperferritinemia, fever and splenomegaly were present in more than 90% of patients, whereas bone marrow hemophagocytosis in 51% of cases only. According to HScore, 34/35 patients had a >75% and 32/35 >93% probability of HLH. Four-year overall survival and HLH-free survival were 17.8% (CI 1.9-33.8) and 23.8% (CI 7.3-40.3), respectively. By multivariate analysis, presence of oedema and hyperbilirubinemia were predictors of death, whereas there was a statistically significant trend for viral infection as predictor of poor prognosis. B-NHL diagnosis was confirmed as associated to a better prognosis in comparison with T/NK lymphoma (4-year HFS 53.3% vs. 0%, p = 0.09) and similar to other aetiologies.

RESUMEN

Previous binding and contractility studies indicate that oxytocin (OT) receptors are present in rabbit epididymis. To investigate the effect of changing endocrine milieu on OT responsiveness, we induced hypogonadism (hypo) in rabbits with a single administration of a long-acting GnRH analog, triptorelin, and we replaced hypogonadal rabbits with different sex steroids. After 2 months from triptorelin administration, testosterone (T) plasma levels were decreased and OT responsiveness abolished. Administration of T to hypo rabbits restored T plasma levels but not OT sensitivity. Because Western blot analysis indicated that both estrogen receptors and aromatase are expressed in the epididymis, we treated hypo rabbits with estradiol valerate (E2v). E2v not only completely restored OT responsiveness but also even amplified it. Accordingly, Northern and Western blot analysis indicated that both OT receptor gene and protein were strongly induced by E2v but not by T. Surprisingly, also the class I estrogen receptor antagonist, tamoxifen restored OT sensitivity in hypo rabbits. To verify whether endogenous estradiol is involved in the regulation of OT receptor responsiveness, we treated intact rabbits with an aromatase inhibitor, letrozole. Blocking aromatase activity almost completely abolished OT sensitivity. These findings suggest a new function of estrogens in the male: regulation of OT responsiveness in epididymis.

RESUMEN

The E170 module was evaluated at 13 sites in an international multicentre study. The objective of the study was to assess the analytical performance of 49 analytes, and to collect feedback on the system's reliability and practicability. The typical, within-run coefficients of variation (CVs) for most of the quantitative assays ranged between 1 and 2% while a range of 2-4% was achieved with the infectious disease methods. Total precision CVs were found to be within the manufacturer's expected performance ranges, demonstrating good concordance of the system's measuring channels and a high reproducibility during the 2-4-week trial period. The functional sensitivity of 11 selected assays met the clinical requirements (e.g., thyreotroponin (TSH) 0.008 mU/l, troponin T 0.02 microg/l, total prostate-specific antigen (PSA) 0.03 microg/l). The E170 showed no drift during an 8-hour period and no relevant reagent carryover. Accuracy was confirmed by ring trial experiments and method comparisons vs. Elecsys 2010. The reliability and practicability of the system's hardware and software met with, or even exceeded, the evaluator's requirements. Workflow studies showed that E170 can cover the combined workload of various routine analysers in a variety of laboratory environment. Throughput and sample processing time requirements were achieved while personnel 'hands-on-time' could be reduced.
