Background: Patients with cardiac complaints but without confirmed diagnosis of coronary heart disease by angiography frequently develop cardiac events in the following years. This follow-up study investigated the frequency of cardiac symptoms and cardiovascular events (CVE) 5 years after initial angiography of patients with nonobstructive coronary artery disease (NobCAD, LIFE Heart study), with the aim to identify gender-specific indicators for CVE. Methods: In 2014/2015, 1462 women and men with NobCAD, defined as no or non-relevant obstructive coronary artery disease were identified among 2660 subjects participating in the observational angiographic LIFE Heart study. Questionnaires of 820 responding patients were analyzed. Results: The median observation time was 55 months. Cardiac symptoms were found in 53.6% of all patients, significantly more often in women than in men (59.4% vs. 48.8%; p = 0.002). CVE occurred in 46.1% of all participants (n = 378/820). Patients with cardiac symptoms had a 2.94 time higher risk for CVE than those without cardiac symptoms (p \textless 0.001). Men with no cardiac symptoms had significantly more CVE (p = 0.042) than women. Common risk factors for CVE comprised cardiac symptoms, atrial fibrillation, and age. Sex-specific risk factors comprised body mass index (BMI) \geq25 kg/m2 for women and anxiety for men. Conclusions: Patients with cardiac symptoms have about three times higher risk for CVE within 5 years than patients without cardiac symptoms. Sex differences exist in patients without symptoms where men were at higher risk for CVE. Atrial fibrillation was the strongest indicator for CVE, whereas anxiety was an indicator only in men and BMI \geq25 kg/m2 only in women, suggesting sex- and gender-specific phenotypic profiles.

Male sex is associated with unfavourable pharmacokinetics and prognosis in elderly patients with diffuse large B-cell lymphoma (DLBCL). We investigated higher rituximab doses for elderly male DLBCL patients. Elderly patients (61-80 years) received 6 cycles CHOP-14 (cyclophosphamide, doxorubicin, vincristine and prednisone at 14-day intervals) and were randomized to 8 cycles rituximab (males 500 mg/m(2) , females 375 mg/m(2) ) every 2 weeks or according to an upfront dose-dense schedule. In 268 (120 females, 148 males) no difference between the standard and the upfront dose-dense rituximab schedule was found (3-year PFS 72% vs. 74%; OS 74% vs. 77%; P = 0.651). The 500 mg/m(2) dose of rituximab for male patients was associated with serum levels and exposure times slightly better than in females and a male/female hazard ratio of 0.9 for progression-free survival (PFS) and 0.8 for overall survival. For elderly males, 500 mg/m(2) was not more toxic than 375 mg/m(2) rituximab, but improved PFS by 32.5% (P = 0.039), with a trend for a (30%) better overall survival (P = 0.076) in a planned subgroup analysis adjusting for International Prognostic Index risk factors. We conclude that the higher rituximab dose for elderly male patients abrogated the adverse prognosis of male sex without increasing toxicity. In the era of personalized medicine, sex-specific pharmacokinetics and toxicities should be investigated for all drugs where these parameters impact on outcome.

PURPOSE: To develop and validate a risk score for relapse in the CNS in patients with diffuse large B-cell lymphoma (DLBCL). PATIENTS AND METHODS: A total of 2,164 patients (18 to 80 years old) with aggressive B-cell lymphomas (80% DLBCL) treated with rituximab and CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone)-like chemotherapy, who were enrolled in studies from the German High-Grade Non-Hodgkin Lymphoma Study Group and the MabThera International Trial, were analyzed for occurrence of relapse/progression in the CNS. The resulting risk model was validated in an independent data set of 1,597 patients with DLBCL identified in the British Columbia Cancer Agency Lymphoid Cancer database. RESULTS: The risk model consists of the International Prognostic Index (IPI) factors in addition to involvement of kidneys and/or adrenal glands (CNS-IPI). In a three-risk group model, the low-risk group (46% of all patients analyzed), the intermediate-risk group (41%), and the high-risk group (12%) showed 2-year rates of CNS disease of 0.6% (CI, 0% to 1.2%), 3.4% (CI, 2.2% to 4.4%), and 10.2% (CI, 6.3% to 14.1%), respectively. Patients from the validation British Columbia Cancer Agency data set showed similar rates of CNS disease for low-risk (0.8%; CI, 0.0% to 1.6%), intermediate-risk (3.9%; CI, 2.3% to 5.5%), and high-risk (12.0%; CI, 7.9% to 16.1%) groups. CONCLUSION: The CNS-IPI is a robust, highly reproducible tool that can be used to estimate the risk of CNS relapse/progression in patients with DLBCL treated with R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy. Close to 90% of patients with DLBCL belong to the low- and intermediate-risk groups and have a CNS relapse risk < 5%; they may be spared any diagnostic and therapeutic intervention. In contrast, those in the high-risk group have a > 10% risk of CNS relapse and should be considered for CNS-directed investigations and prophylactic interventions.

In the NORRE study (EHJCVI (2014) 15, 680 – 690) normal values determined by echocardiography were published in healthy subjects (n = 734) with mean age of 46+13 years (range: 20 – 78). Left ventricular (LV)-volumes showed good correlations to the participants' (pts') age. LV-volumes were decreased and LV ejection fraction (EF) was increased according to the increase of the pts' age. A significant correlation between age and LV-mass was only found in women. Left atrial (LA)-volumes did not significantly change with age. Parameters of diastolic function showed a strong age-dependency (decrease of E/A-ratio; increase of E/E'-ratio). In the present LIFE-Adult analysis echocardiographic parameters were compared to the NORRE data. In 773 pts (326 males and 447 females; median age: 51 years), standardised transthoracic echocardiography was performed according to the national and international recommendations. The following parameters were analysed: LV- and LA-volume analyses by M-Mode measurements and 2D-LV planimetry, maximum E-and A-velocity, E/A-ratio and E/E'-ratio. The cohort was divided in age related subcohorts between 20 – 40, 41 – 50 and 51 – 60 years. Mean LV-diameter was 54 ± 5 mm (males) and 49 ± 4 mm (females). There was no age-dependency in males, but a tendency of LV-diameter increase in females. Mean LA diameter was 39 ± 4 mm in males and 35 ± 4 mm in females. Mean LA-diameter-index was 20 ± 2 mm/m2 (males) and 20 ± 3 mm/m2 (females) showing Age-dependency of an increasing LA-diameter in males and females. LV mass-index was 100 ± 20 g/m2 (males) and 83 ± 19 g/m2 (females) showing a tendency of increasing LV mass-index with age in males and females. Subsequently, septal and posterior wall thickness slightly increases with age. No differences of LVEF with increase of the pts' age could be observed. E/A-ratio was decreased and E/E'-ratio was increased with increase of the pts' age. The analysis of the echocardiographic parameters of the LIFE-Adult trial showed differences of the age-dependency in comparison to the NORRE data.

Abstract (Expand)

The E/E'-ratio is used as a surrogate parameter for the estimation of the left ventricular enddiastolic pressure. It is assumed that chronic systolic and diastolic heart failure is associated with E/E'-values of more than 15 or at least with intermediate values between 9 – 5. The aim of the present retrospective analysis of the epidemiological echocardiographic cohort of the LIFE-Adult study (Leipzig Research Centre for Civilization Diseases) was to evaluate the correlation of NT-BNP (N-terminales propeptid BNP) values to the E/E'-ratio by the assessment of left ventricular diastolic function in this cohort. In 773 participants (pts) standardised transthoracic echocardiography was performed and in 748 pts NT-BNP was analysed. The E/E'-ratio was determined according to the international recommendations by measuring the maximum velocity of the early diastolic inflow by pulsed wave Doppler echocardiography and the basal septal maximum myocardial velocity by tissue Doppler echocardiography at early diastole. NT-BNP was determined using commercially available diagnostic tests. Pathological NT-BNP levels were assumed in the range > 222pg/ml. Normal E/E'-ratios as well as normal NT-BNP levels were observed in 91% of all participants. In 1.4% of the pts elevated NT-BNP levels were found in the presence of normal E/E'-ratio. In contrast in 1.1% of the pts elevated E/E'-ratios were found in the presence of normal NT-BNP levels. Most of the pts with heart failure detected by NT-BNP vales > 222pg/ml also showed intermediate E/E'-ratios between 9 and 15 (42pts). In only 0.8% of the pts (5 pts) significantly elevated E/E'-ratios > 15 and pathological NT-BNP levels could be observed (see fig). Only 4 pts with elevated NT-BNP values showed left ventricular systolic dysfunction. E/E'-ratio has to be verified to be suitable for the detection of heart failure patients. The present data show that E/E'-ratio of > 15 is not well correlated to increased NT-BNP levels.

Abstract (Expand)

Treatment of relapse and primary progression in aggressive lymphoma remains unsatisfactory; outcome is still poor. Better treatment strategies are much needed for this patient population. The R1 study is a prospective multi-center phase I/II study evaluating a dose finding approach with a triple transplant regimen in four BEAM dose levels in patients with relapsed aggressive non-Hodgkin lymphoma. The aim of the study was to determine feasibility, toxicity, and remission rate. In a total of 39 patients (pts.) enrolled in the study, 24 pts. were evaluated in the following analysis. Twenty pts. had aggressive B cell lymphoma, and two pts. had T cell lymphoma. All evaluated patients responded to DexaBEAM with a sufficient stem cell harvest. The phase I/II study was started with BEAM dose level II. Four patients were treated at dose level II, and 20 pts. were treated at dose level III. Due to the early termination of the study, dose levels I and IV were never administered. Sixteen pts. completed therapy according to protocol, and eight pts. (33.3 %) stopped treatment early. Infections (27 %) and stomatitis (13 %) were the most frequent grade III/IV non-hematologic toxicities. Thirteen percent of patients presented with severe grade III/IV lung toxicity during modified BEAM (m-BEAM). Fourteen pts. achieved a complete response (CR), one pt. achieved no change (NC), six pts. had progressive disease (PD), and two pts. died; for one pt., outcome is not known. One-year and 3-year event-free survival (EFS) was 38 and 33 %, respectively. Overall survival (OS) after 1 and 3 years was 50 and 38 %. In conclusion, dose escalation of standard BEAM is not feasible due to toxicity.
