High sensitive TROponin levels In Patients with Chest pain and kidney disease: A multicenter registry - The TROPIC study.

Background: Accuracy of high sensitive troponin (hs-cTn) to detect coronary artery disease (CAD) in patients with renal insufficiency is not established. The aim of this study was to evaluate the prognostic role of hs-cTn T and I in patients with chronic kidney disease (CKD).

Methods: All consecutive patients with chest pain, renal insufficiency (eGFR < 60 mL/min/1.

Recent advances in the management of pericardial diseases.

Pericardial diseases are relatively common in clinical practice either as isolated diseases or part of an underlying or systemic disease. Recent advances in the diagnosis and treatment have greatly improved the clinical management and lead to consensus documents on multimodality imaging and new guidelines on the diagnosis and therapy of pericardial diseases. The aim of the present paper is to summarize available evidence in order to provide an updated and comprehensive review on the recent advances in the management of pericardial diseases.

Combinations of colistin solutions and nebulisers for lung infection management in cystic fibrosis patients.

In this work different nebulisers were investigated in order to assess their efficiency in combination with colistimethate sodium (CMS) inhalation products. Four nebulisers, namely I-neb(®), Aeroneb(®) Go, eFlow(®)rapid and PARI LC(®) Sprint were studied in terms of delivered dose (DD), drug delivery rate (DDR) and respirable dose (RD) of CMS. The goal was to provide scientific data to physicians for prescribing the most appropriate nebuliser for the CMS specific user.

Thirty-day readmission rates after PCI in a metropolitan center in Europe: incidence and impact on prognosis.

Introduction: Thirty-day readmission rates after percutaneous coronary intervention (PCI) have been related to adverse prognosis, and represent one of the most investigated indicators of quality of care. These data, however, derive from non-European centers evaluating all-cause readmissions, without stratification for diagnosis.

Methods: All consecutive patients undergoing PCI at our center from January 2009 to December 2011 were enrolled.

Appraising failure of surgical and percutaneous revascularization: long term outcomes from an observational registry.

Aim: Many randomized trials have compared coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) in terms of efficacy, but data comparing outcomes of patients in which these two techniques have failed are lacking.

Methods: We included patients undergoing PCI at our center between July 2002 and December 2004. Subjects were distinguished in 2 groups: those with at least one occluded or stenotic saphenous vein graft (CABG failure), and those with at least one stent with angiographically documented restenosis (PCI failure).

Percutaneous coronary intervention in nonagenarian: a meta-analysis of observational studies.

Background: Developed countries are facing a sustained increase in life expectancy. Along with all social and cultural implications of increase lifespan, very elderly patients are undergoing percutaneous coronary intervention (PCI) with increasing frequency. However, there is limited evidence to guide clinicians in evaluating pros and cons of PCI in this very frail patient population.

Diffuse coronary disease: short- and long-term outcome after percutaneous coronary intervention.

Aim: The aim of this study was to evaluate short- and long-term results of PCI (percutaneous coronary intervention) in patients with small vessel coronary artery disease and the prognostic impact of the extension and the length of coronary lesions.

Methods And Results: All consecutive patients treated with PCI in our centre between July 2002 and December 2004 were included and divided into two groups according to the diameter of the implanted stents: small vessel disease was defined as requiring implantation of stents < 2.75 mm in diameter.

Short and long term outcome of percutaneous coronary intervention with drug eluting stent and bare metal stent in patients with chronic kidney disease.

Aim: Coronary artery disease represents the most important cause of mortality and morbidity in chronic kidney disease (CKD). Despite continuous improvements in percutaneous coronary intervention (PCI), CKD is still associated with more adverse events after PCI. We performed a retrospective study to compare bare metal stents (BMS) versus drug eluting stents (DES) in CKD.

Refractory anaemia with excess of blasts in transformation re-evaluated with the WHO criteria: identification of subgroups with different survival.

One of the major changes suggested by the World Health Organization (WHO) classification with respect to the French-American-British (FAB) proposal for myelodysplastic syndromes (MDS) was to lower the bone marrow (BM) blast count from 30 to 20%, thus eliminating the refractory anaemia with excess of blasts in transformation (RAEB-t) category. However, a general consensus has not been reached, and several authors still retain RAEB-t as an MDS sub-entity. We re-evaluated our series of 74 patients classified as RAEB-t according to the FAB criteria by stratifying them into two subsets: patients with at least 5% peripheral blast (PB) cells but with BM blasts <20% (group I) and patients with BM blastosis between 20 and 30% and PBs <5% (group II).

Apoptosis susceptibility and cell-cycle distribution in cells from myelodysplastic syndrome patients: modulatory in-vitro effects of G-CSF and interferon-alpha.

Susceptibility to apoptosis varies in different forms of myelodysplastic syndromes (MDS). Our in vitro study aimed at better defining the cell kinetic profile by investigating whether G-CSF and interferon-alpha (IFNalpha) were capable of controling apoptotic/proliferative mechanisms in RAEB as well as in RAEB-t forms. Apoptosis and cell-cycle distribution were measured in mononuclear and in CD34+ cells from bone marrow samples of 27 MDS patients with RAEB (n = 15) and RAEB-t (n = 12).

Detection of BCR/ABL rearrangements in adult acute lymphoblastic leukemia using a highly sensitive interphase fluorescence in situ hybridization method (D-FISH).

Introduction: One hundred-and-six adult cases of acute lymphoblastic leukemia were prospectively investigated using a highly sensitive interphase fluorescence in situ hybridization assay which utilizes DNA probes that detect a double BCR/ABL fusion signal (D-FISH) in cells carrying the t(9;22) to evaluate the reliability and specificity of this method for the detection of the Ph translocation. The results were compared with those obtained in the same cases by conventional cytogenetics and by reverse-transcription polymerase chain reaction.

Materials And Methods: The study was performed using DNA probes that span the common breakpoints of the t(9;22) translocation and that detect a double BCR/ABL fusion in cells carrying this karyotypic anomaly, one on the abnormal chromosome 9 and one on the Ph chromosome.

Use of dual-color interphase FISH for the detection of inv(16) in acute myeloid leukemia at diagnosis, relapse and during follow-up: a study of 23 patients.

The value of dual-color fluorescence in situ hybridization (FISH) for the detection of inv(16), using two contigs of cosmid probes mapping on both sides of the chromosome 16p breakpoint region, was evaluated in 23 acute myeloid leukemias (AML) in different phases of the disease. At diagnosis interphase FISH detected inv(16) in 19/19 (100%) cases with conventional cytogenetics (CC) evident aberration and excluded the rearrangement in two patients with CC suspected inv(16). Moreover, it also identified an associated del(16p) in two patients.

Sequential molecular monitoring of chimerism in chronic myeloid leukemia patients receiving donor lymphocyte transfusion for relapse after bone marrow transplantation.

Recent observations of chimerism in patients relapsed following an allotransplant suggest the persistence of immunotolerance, thus offering a biologic rationale for the use of donor lymphocyte transfusion (DLT). In this study, we have analyzed by PCR amplification of several VNTR regions, sequential bone marrow and peripheral blood DNA samples in four patients who received DLT for CML relapse after bone marrow transplantation. Prior to DLT, all patients showed mixed chimerism in peripheral blood cells while two had mixed chimerism and two no chimerism in the BM.

Combined cytogenetic, FISH and molecular analysis in acute promyelocytic leukaemia at diagnosis and in complete remission.

This study reports the results of a simultaneous application of cytogenetic fluorescence in situ hybridization (FISH) and molecular analysis (RT-PCR) in 28 APL cases (23 M3 and five M3v; 26 studied at diagnosis and two at relapse). FISH on metaphases identified the t(15;17) in all cases who were positive for the PML/RAR alpha transcript by RT-PCR. Conventional cytogenetics revealed the t(15;17) in only 68% of cases.

Acute leukemia presenting a variant Ph chromosome with p190 expression, dup 3q and -7, developed after malignant lymphoma treated with alkylating agents and topoisomerase II inhibitors.

We describe the occurrence of a variant Ph chromosome (v-Ph) in a therapy-related acute leukemia (s-AL), developed after 8-year treatment for a NHL with alkylating agents, anthracyclines and topoisomerase II inhibitors. The v-Ph originated from a complex t(2;9;22) translocation, expressed a p190bcr-abl fusion protein, and was associated to other specific changes, such as dup(3) (q21q26) and -7. The s-AL, apparently not preceded by a dysplastic phase, presented with signs of trilineage dysplasia with 10% micromegakaryocytes; it was classified as M5 according to FAB.

Application of fluorescence in situ hybridization in defining a complex t(9;21;22) Ph formation.

We describe the application of fluorescence in situ hybridization (FISH) in a case of suspected chronic myelogenous leukemia (CML), cytogenetically characterized by a t(21;22) with no clear involvement of chromosome 9. The dual color FISH technique, performed using specific painting probes for chromosomes 9,21,22 and a BCR/ABL translocation probe, enabled us to confirm the diagnosis of CML by detecting the BCR/ABL rearrangement on chromosome 22q and the involvement of chromosome 9 in a variant translocation t(9;21;22).

Trisomy 14 in hematologic diseases. Another non-random abnormality within myeloid proliferative disorders.

Two cases of myelodysplastic syndrome (MDS) and a case of acute nonlymphoblastic leukemia (ANLL) with a trisomy 14 are presented. The series of results derived from our cases, and those previously reported, strongly suggest that this anomaly may be another nonrandom change, confined within myeloid disorders and associated with patients' advanced age, marked tendency to bone marrow dysplastic features, normal platelet values, and not unfavorable prognosis.

Management of chronic myeloid leukemia in chronic phase with autologous stem cell transplantation and alpha-2 interferon: cytogenetic and clinical results.

Forty-eight patients with chronic myeloid leukemia (CML) in chronic phase (CP) were treated by autologous stem cells transplantation (ASCT) and alpha Interferon (IFN) with three approaches: 1) ASCT at diagnosis followed by IFN, 2) ASCT post IFN with cells collected after an interval from IFN discontinuance, followed by IFN, 3) ASCT in patients selected by cytoconversion obtained with IFN, performed soon after IFN discontinuance. Following ASCT, a major karyotype response (more than 65% Ph1 negative cells, MKR) was observed at least once in 40%, 53% and 83% of patients from the three groups, respectively. At last follow-ups (median 39, 40 and 21 months, respectively) 19%, 13% and 67% of patients still present a MKR with 2 patients from group 1 and 4 patients from group 3 being 100% Ph' negative.

Ph-negative and bcr-negative atypical chronic myelogenous leukemia: biological features and clinical outcome.

We report the clinical, hematologic, cytogenetic, and molecular characteristics of 13 patients with Philadelphia-negative (Ph-), bcr-negative atypical chronic myelogenous leukemia (CML). In the majority of cases, the phenotypic features at presentation resembled those of typical CML. However, these patients presented with a higher median age, lower median hemoglobin levels, and lower leukocyte and platelet counts than patients with Ph-positive CML.

Interferon therapy for Ph1 positive CML patients relapsing after T cell-depleted allogeneic bone marrow transplantation.

Eighteen chronic myeloid leukemia patients with hematological (four patients) or only cytogenetic (14 patients) relapse occurring after T cell-depleted allogeneic bone marrow transplantation (BMT) have been treated with alpha 2b interferon (IFN) at a starting dose of 5 x 10(6) i.u./m2 subcutaneously three times a week.

Cytogenetic follow-up after allogeneic bone-marrow transplantation for Ph1-positive chronic myelogenous leukemia.

Serial cytogenetic studies were carried out on 36 patients with Ph1-positive chronic myelogenous leukemia treated with allogeneic bone-marrow transplantation from unlike sex (21 patients) or like sex (15 patients) donors. Fourteen of the 21 sex-mismatched and 12 of the 15 sex-matched donor marrows were T cell depleted. Disease relapse was documented in 19 of the 26 patients who received T cell-depleted marrow, and in none of the 10 patients who received non-T cell-depleted marrow.
