Background and Aims: Little is known about the risk factors of colectomy in patients with ulcerative colitis (UC) under thiopurine treatment. The aim of the study was to determine the prevalence and the predictive risk factors of colectomy in an extensive cohort of patients with UC treated with thiopurines in Spain. Methods: Among 5753 UC patients, we identified those diagnosed between 1980 and 2009 and treated with azathioprine or mercaptopurine (AZA/MP). We analyzed the age at diagnosis, familial history of IBD, extraintestinal manifestations (EIMs), disease extent, smoking status and treatment requirements (AZA/MP, cyclosporine (CsA) or anti-TNFα). Colectomies for dysplasia or cancer were excluded. Survival analysis and Cox proportional hazard regression were performed. Results were reported as hazard ratios (HR) with 95% CI. Results: Among the 1334 cases included, 119 patients (8.9%) required colectomy after a median time of 26. months (IQR 12-42) after AZA/MP initiation. Independent predictors of colectomy were: Extensive UC (HR 1.7, 95% CI: 1.1-2.6), EIMs (HR 1.5, 95% CI: 1.0-2.4), need for antiTNFα (HR 2.3, 95% CI: 1.5-3.4) and need for CsA (HR 2.4, 95% CI: 1.6-3.7). Patients requiring early introduction of AZA/MP had an increased risk of colectomy with a HR of 4.9 (95% CI: 3.2-7.8) when AZA/MP started in the first 33. months after UC diagnosis. Conclusions: Nearly one-tenth of patients with UC under thiopurines require colectomy. Extensive UC, EIMs, need for CsA or anti-TNFα ever and an early need for AZA/MP treatment were associated with a higher risk of colectomy. These risk factors of colectomy could help to stratify risk in further controlled studies in UC. © 2014 European Crohn's and Colitis Organisation.

Mantle cell lymphoma (MCL) is a mature B-cell neoplasm with an aggressive behavior, characterized by the t(11;14)(q13;q32). Several secondary genetic abnormalities with a potential role in the oncogenic process have been described. Studies of large MCL series using conventional cytogenetics, and correlating with proliferation and survival, are scarce. We selected 145 MCL cases at diagnosis, displaying an aberrant karyotype, from centers belonging to the Spanish Cooperative Group for Hematological Cytogenetics. Histological subtype, proliferative index and survival data were ascertained. Combined cytogenetic and molecular analyses detected CCND1 translocations in all cases, mostly t(11;14)(q13;q32). Secondary aberrations were present in 58% of patients, the most frequent being deletions of 1p, 13q and 17p, 10p alterations and 3q gains. The most recurrent breakpoints were identified at 1p31-32, 1p21-22, 17p13, and 1p36. Aggressive blastoid/ pleomorphic variants displayed a higher karyotypic complexity, a higher frequency of 1p and 17p deletions and 10p alterations, a higher proliferation index and poor survival. Gains of 3q and 13q and 17p13 losses were associated with reduced survival times. Interestingly, gains of 3q and 17p losses added prognostic significance to the morphology in a multivariate analysis. Our findings confirm previous observations indicating that proliferation index, morphology and several secondary genetic alterations (3q gains and 13q and 17p losses) have prognostic value in patients with MCL. Additionally, we observed that 3q gains and 17p losses detected by conventional cytogenetics are proliferation-independent prognostic markers indicating poor outcome. VVC 2010 Wiley-Liss, Inc.

Circadian rhythm interactions of hemostatic factors can modify tissue plasminogen activator (tPA) effects. We assess the relationship of the time frame of intravenous tPA administration with the outcome of patients with acute ischemic stroke (AIS). We studied 135 consecutive patients with AIS and transcranial duplex documented middle cerebral artery (MCA) occlusion treated with intravenous tPA. Complete recanalization was defined as total improvement on thrombolysis in brain ischemia (TIBI) grades 2h after tPA infusion. Clinical response was evaluated by the modified Rankin scale at 90 days. We determined plasminogen activator inhibitor-1 (PAI-1) levels in 33 patients with available plasma samples before treatment. Our results are follows: 92 (68.1) patients were treated in the diurnal (9:0021:00) and 43 (31.8) in the nocturnal period (21:009:00). Complete recanalization was recorded in 52135 (38.5) patients. Both the rate of complete recanalization (45.6 vs. 23.2; p.01) and good clinical outcome (64.1 vs. 44.2; p.02) were significantly higher in the group of diurnal tPA administration compared with those treated in the nocturnal period. The adjusted odds ratio (OR) of diurnal tPA treatment for complete MCA recanalization was 2.37 (95 confidence interval [CI], 1.025.52; p.045). Diurnal tPA infusion significantly improved the overall distribution of scores on the modified Rankin scale, as compared with nocturnal treatment (OR, 2.07; 95 CI, 1.164.64 by ordinal regression analysis). Low PAI-1 levels were associated with complete recanalization but did not significantly differ between the two time frames. In conclusion, diurnal administration of tPA is associated with complete MCA recanalization and better functional outcome at 90 days in patients with AIS.

Antiretroviral drugs in Spain are delivered by law only in hospital pharmacies. Commercial packages meet variable quality standards when dispensed drugs are returned due to treatment changes or adherence problems Nearly 20-25% of the initial regimens will be changed at 48 weeks for different reasons. We evaluated the economic impact on public health system of the inability of using returned drugs due to inefficient packaging.We defined socially efficient packaging as the best adapted one to being delivered in unit dose to outpatients and classified: Class A - Drug packed in unit doses with complete info (name of drug, dosage in mg, lot, and expiring date) in each unit, maintaining complete information of the drug if returned when the external package is opened. Class B - packed in blisters with complete info in the blister, but not in unit doses, without special conservation conditions (should be re-packed in unit doses in the pharmacy before its dispensation to assure a class A excellence). Class C - packed in plastic containers with complete info written only on a label over the container, would allow repackaging only before its initial delivery, but not when returned. Class D - drug packed in plastic containers with manufacturers warning that the product cannot be placed outside of the original package due to special conditions of conservation (fridge, humidity) that doesnt allow a unit dose repackaging or reusing an opened container. We analysed a 12-month period (July 2011-June 2012) in a hospital-based HIV outpatient pharmacy that serves 2413 treated individuals.Patients generated 23,574 visits to pharmacy, and received 48,325 drug packages, with 2.529.137 pills delivered. The patients suffered 1051 treatment changes for any reason. A total amount of 122.945 in treatment were returned to pharmacy in opened packages during the study period. 47.139.91 would be totally lost, mainly due to being packaged in class C and D boxes, the equivalent of treating 78 patients with rilpivirine/TDF/FTC during 1 month. Class A and B packages in bad condition represented only 1.1% of the cost. However, 75.805 came from returned packages in good condition that could potentially be reused. Most of the treatment changes were not foreseeable.A significant economic budget is lost through socially inefficient antiretroviral packages. Newer treatments are packaged in C and D categories, therefore maintaining these hidden costs in the near future. Any improvement in the excellence of packaging by the manufacturer, and favouring the choice of drugs supplied through efficient packages (when efficacy, toxicity and convenience are similar) should minimize the treatment expenditures paid by national health budgets.
