Effects of High Density Lipoprotein Raising Therapies on Cardiovascular Outcomes in Patients with Type 2 Diabetes Mellitus, with or without Renal Impairment: The Action to Control Cardiovascular Risk in Diabetes Study

© 2016 S. Karger AG, Basel. Copyright: All rights reserved. Background: The role of high density lipoprotein-raising interventions in addition to statin therapy in patients with diabetes remains controversial. Chronic kidney disease (CKD) is a strong modifier of cardiovascular (CV) outcomes. We therefore investigated the impact of CKD status at baseline on outcomes in patients with diabetes randomized to standard statin or statin plus fenofibrate treatment in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) lipid trial. Methods: Among 5,464 participants in the ACCORD lipid trial, 3,554 (65%) were free of CKD at baseline, while 1,910 (35%) had mild to moderate CKD. Differences in CV outcomes during follow-up between CKD and non-CKD subgroups were examined. In addition, the effect of fenofibrate as compared to placebo on CV outcomes was examined for both subgroups. Results: All CV outcomes were 1.4-3 times higher among patients with CKD as compared to non-CKD patients. In patients with CKD, the addition of fenofibrate had no effect on any of the primary or secondary outcomes. In patients without CKD, however, the addition of fenofibrate was associated with a significant 36% reduction of CV mortality (hazards ratio [HR] 0.64; 95% CI 0.42-0.97; p value for treatment interaction \u3c0.05) and 44% lower rate of fatal or non-fatal congestive heart failure (CHF; HR 0.56; 95% CI 0.37-0.84; p value treatment interaction \u3c0.03). Conclusions: For patients with type 2 diabetes at high CV risk but no CKD, fenofibrate therapy added to statin reduced the CV mortality and the rate of fatal and non-fatal CHF

Chronic kidney disease and intensive glycemic control increase cardiovascular risk in patients with type 2 diabetes.

Results of the main Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial indicate that intensive glucose lowering increases cardiovascular and all-cause mortality. As the contribution of mild-to-moderate chronic kidney disease (CKD) to these risks is not known, we assessed the impact on cardiovascular outcomes in this population. Renal function data were available on 10,136 patients of the original ACCORD cohort. Of those, 6,506 were free of CKD at baseline and 3,636 met the criteria for CKD. Participants were randomly assigned to a treatment strategy of either intensive or standard glycemic goal. The primary outcome, all-cause and cardiovascular mortality, and prespecified secondary outcomes were evaluated. Risk for the primary outcome was 87% higher in patients with than in those without CKD (hazard ratio of 1.866; 95% CI: 1.651-2.110). All prespecified secondary outcomes were 1.5 to 3 times more frequent in patients with than in those without CKD. In patients with CKD, compared with standard therapy, intensive glucose lowering was significantly associated with both 31% higher all-cause mortality (1.306: 1.065-1.600) and 41% higher cardiovascular mortality (1.412: 1.052-1.892). No significant effects were found in patients without CKD. Thus, in high-risk patients with type II diabetes, mild and moderate CKD is associated with increased cardiovascular risk. Intensive glycemic control significantly increases the risk of cardiovascular and all-cause mortality in this population

Antinociception Depends on the Presence of G Protein γ\u3csub\u3e2\u3c/sub\u3e- Subunits in Brain

We have shown previously [Hosohata, K., Logan, J.K., Varga, E., Burkey, T.H., Vanderah, T.W., Porreca, F., Hruby, V.J., Roeske, W.R., Yamamura, H.I., 2000. The role of the G protein γ2 subunit in opioid antinociception in mice. Eur. J. Pharmacol. 392, R9-R11] that intracerebroventricular (i.c.v.) treatment of mice with a phosphorothioate oligodeoxynucleotide antisense to the γ2 subunit (Gγ2) of the heterotrimeric G proteins (antisense ODN) significantly attenuates antinociception by a δ-opioid receptor agonist. In the present study, we examined the involvement of Gγ2 in antinociception mediated by other (μ- or κ-opioid, cannabinoid, α2-adrenoreceptor) analgesic agents in a warm (55°C) water tail-flick test in mice. Interestingly, i.c.v. treatment with the antisense ODN attenuated antinociception by each analgesic agent. Missense phosphorothioate oligodeoxynucleotide treatment, on the other hand, had no effect on antinociception mediated by these agonists. The antinociceptive response recovered in 6 days after the last antisense ODN injection, indicating a lack of nonspecific tissue damage in the animals. These results suggest a pervasive role for the G protein γ2 subunits in supraspinal antinociception
