Background: Red blood cell distribution width (RDW) is a measure of the degree of heterogeneity of erythrocyte volume. Higher RDW levels are associated with increased mortality among patients with acute coronary syndrome (ACS), heart failure and other cardiovascular diseases. The association between RDW levels and clinical outcomes in patients admitted for further evaluation of chest pain is not known. Methods: A retrospective analysis of patients hospitalised with chest pain 2010-2016 was conducted. Patients diagnosed with ACS in the emergency department (ED) were excluded. Patients were divided into tertiles according to baseline ED RDW levels (≤13.1%, 13.1%13.9%). Study endpoints were diagnosis of ACS during the index hospitalisation and ACS and all-cause mortality during a median follow-up of 3.3 ± 1.9 years. Results: Included were 13,018 patients (mean age 58 ± 13 years, 61% male). Increased RDW levels were associated with higher rates of ACS in the index hospitalisation (6.1%, 6.6% and 8.1% for 1st, 2nd and 3rd tertiles, respectively, p  < .01), ACS during follow-up (8.6%, 10.1% and 13.4%, respectively, p  < .01), and with all-cause mortality during follow-up (2.5%, 4.6% and 15.4%, respectively, p  < .01). In multivariate analysis, RDW levels >13.9% (vs. ≤13.1%) were associated with ACS in the index hospitalisation (adjusted OR 1.25, 95% CI 1.04-1.51, p  = .02), ACS during follow-up (adjusted OR 1.35, 95% CI 1.05-1.73, p  = .02) and with all-cause mortality (adjusted HR 2.41, 95% CI 1.94-2.99, p  < .01). Conclusion: In this retrospective study of patients hospitalised with chest pain, higher RDW levels were associated with future ACS and long-term mortality.

ABSTRACT Focal amplification of specific regions of the genome creates high copy number and expression of oncogenes in tumors. By applying fluorescence in situ hybridization (FISH) to leukocytes of hepatitis C (HCV) patients and non-Hodgkin lymphoma (NHL) patients, we estimated gene dosage of the TERC gene at 3q26.3. Higher TERC copy numbers were found in NHL at diagnosis compared to HCV patient groups. Higher TERC copy numbers were also observed in NHL patient at diagnosis and relapse compared to patients in remission. We believe that the TERC gene amplification is involved in the process of genetic instability leading to tumor genesis such as in NHL.

Telomeres of tumor nuclei tend to form aggregates (TA). The aim of this study was to estimate the TA formation in leukocytes of patients with chronic hepatitis C (HCV) which is considered to be premalignant disease, in patients of HCV who eradicated the virus. PNA Telomere kit (Dako) was used to evaluate the TA formation with the utilization of 2D fluorescence microscopy. A higher rate of TA was found in both HCV groups as compared to controls. Our results indicate that HCV patients have some of the components that create the cascade of events leading to malignancies.

We report a patient with chronic hepatitis B infection who developed lymphoma and was treated with concomitant cytotoxic and antiviral therapy. In contrast to the expected life threatening fulminant hepatitis that is often reported in this clinical setting, in our patient normalization of liver function tests with temporary loss of viral replication markers were seen. The implications of this rare clinical and serological course are discussed.

Intensive combination chemotherapy administered to patients with non-Hodgkin's lymphoma (NHL) is inevitably associated with neutropenia and fever. However, the subset of patients who are at increased risk for myelotoxicity has not been clearly identified as yet. We evaluated 58 patients with NHL in order to verify whether bone marrow involvement (BMI) at diagnosis is a risk factor for neutropenia and infection following intensive chemotherapy. Patients with bone marrow involvement had significantly lower neutrophil counts both at diagnosis and following chemotherapy. An higher percentage of patients with BMI developed neutropenia (< 1000/mm3) following chemotherapy. Furthermore events of febrile neutropenia were more frequently encountered in patients with BMI. We conclude that BMI in patients with NHL is a risk factor for chemotherapy induced neutropenia and fever. The role of colony stimulating factors, administered in an attempt to prevent this complication, should be explored.
