Cardiac Autonomic Function Correlates with Arterial Stiffness in the Early Stage of Type 1 Diabetes

Arterial stiffness is increased in type 1 diabetes (T1D), before any clinical complications of the disease are evident. The aim of the present paper was to investigate the association between cardiac autonomic function and arterial stiffness in a cohort of young T1D patients, without history of hypertension and any evidence of macrovascular and/or renal disease. Large artery stiffness was assessed by measurement of carotid-femoral pulse wave velocity (PWV). Cardiac autonomic function was assessed by the cardiovascular tests proposed by Ewing and Clarke. Patients with a high cardiac autonomic neuropathy score (≥4) had significantly higher PWV than those with a low score (0-1). A negative, heart rate-independent, correlation between PWV and heart rate variation during respiration was observed (r = −0.533,  P < 0.001). In multivariable analysis, E/I index was the strongest correlate of PWV (β-coefficient = −0.326, P = 0.002). Cardiac parasympathetic function is a strong predictor of large arterial stiffness, in young T1D patients free of macrovascular and renal complications

Arterial stiffness is inversely related to plasma adiponectin levels in young normotensive patients with type 1 diabetes

OBJECTIVE This study investigated the association between arterial stiffness and plasma adiponectin in patients with type 1 diabetes. RESEARCH DESIGN AND METHODS Participants were normotensive patients with type 1 diabetes who were up to age 40 years. Subjects on statins with macrovascular disease or overt nephropathy were excluded. Large artery stiffness was assessed by measurement of carotid-femoral pulse wave velocity (PWV), whereas plasma adiponectin was measured by radioimmunoassay. RESULTS Data from 80 patients (age 27.1 ± 6.1 years, BMI 24.2 ± 3.1 kg/m2, HbA1c 7.5 ± 1.6%, 39 men, adiponectin 13.9 ± 6.7 μg/mL, and PWV 5.6 ± 0.9 m/s) were analyzed. Log adiponectin inversely correlated with age-adjusted PWV (r = −0.291, P = 0.009) and waist circumference (r = −0.427, P < 0.001). In a fully adjusted model, age, expiration/inspiration index, and log adiponectin were independently associated with PWV, explaining 39.6% of its variance. CONCLUSIONS Arterial stiffness is inversely related to adiponectin concentration in young patients with type 1 diabetes without major complications

The continuation of bevacizumab following disease progression in patients with metastatic colorectal cancer offers a survival benefit

Background/Aims: There is little information in the literature on the use of bevacizumab (BV) combination chemotherapy in multiple lines with regimens including irinotecan and oxaliplatin, in metastatic colorectal cancer (mCRC) patients with disease progression. The aim of this small retrospective institutional study is to compare the efficacy and safety of the continuation of BV in combination with various chemotherapeutic agents, within the framework of multiple line therapy in progressed mCRC patients. Methodology: Our retrospective study included 21 patients with mCRC that had received at least one course of irinotecan-based or oxaliplatin-based chemotherapy with BV before disease progression. BV treatment was continuously dispensed after disease progression. Sub-group analysis was performed in terms of age, site of metastases, spread and co-morbidity. Results: The median overall survival (OS) was 23+ months (range 4-51 months) with no statistically significant differences between the aforementioned subgroups of patients, except from the subgroup according to spread (p=0.044). Time to progression was 17 months. Anemia (all grades) was reported in 33.3% of the patients, while hemorrhage and thrombosis were reported in 28.6% and 14.3%, respectively. Conclusions: Multiple line treatment in advanced colorectal cancer, including BV combined with standard chemotherapy, may improve OS with an acceptable toxicity profile in patients with mCRC after disease progression. © H.G.E.

Survival benefit with the combination of docetaxel, gemcitabine and erlotinib in advanced and/or metastatic pancreatic cancer patients

Background/Aims: Although research on new effective treatments against pancreatic cancer is intense, limited therapeutic schemes are currently approved. The aim of the present study was to record the efficacy and safety of gemcitabine-erlotinib plus docetaxel combination therapy in patients with advanced and/or metastatic pancreatic cancer. Methodology: Twenty-five chemotherapy naive patients with histologically confirmed unresectable pancreatic cancer and documented extrapancreatic metastases, received biweekly gemcitabine 1,500mg/m2 during a 28-day long cycle; daily erlotinib 100mg per os; and docetaxel 80mg/m2 as intravenous infusion administered every 15 days. Patients were monitored every 4 cycles for survival, adverse events and tumour response with Computed Tomography scans. Results: Patients received 153 cycles in total, with a median of 7.64 cycles (range, 1-24). The median overall survival was 10 months and 45% of the patients reached and surpassed 1-year survival. No grade TV toxicities were recorded. The only grade III recorded toxicities were thrombopenia (4 patients, 16%), anaemia (1 patient, 4%) and neutropenia (1 patient, 4%). Overall the most frequently experienced adverse events were grade I anaemia (18 patients, 72%) and grade II rash (13 patients, 52%). Conclusions: Biweekly gemcitabine with erlotinib plus docetaxel administration is a practical alternative to pancreatic cancer treatment, presenting comparable results to weekly gemcitabine administration. © H.G.E.
