Diabetic dyslipidemia and cardiovascular risk

Clinical outcomes and risk factors for posterior reversible encephalopathy syndrome in systemic lupus erythematosus: a multicentric case-control study

BACKGROUND

Posterior reversible encephalopathy syndrome (PRES) is a well-known but rare complication in patients (<1%) with systemic lupus erythematosus (SLE). However, current epidemiological data are quite scant. The aim of the present study was to describe potentially unrecognised risk factors.

PATIENTS AND METHODS

We performed a multicentre, retrospective case-control study in Mexico between 1999 and 2014. We included a total of 168 patients who accounted for 77 episodes of PRES, as follows: SLE/PRES, 43 patients with 48 episodes; SLE without PRES, 96 patients; and PRES without SLE, 29 patients. SLE diagnosis was considered when patients fulfilled ≥4 American College of Rheumatology criteria. PRES was defined by reversible neurological manifestations and MRI changes.

RESULTS

Patients with SLE/PRES were younger, presented with seizures as the most common manifestation (81%) and 18% had the typical occipital MRI finding. Hypertension (OR=16.3, 95% CI 4.03 to 65.8), renal dysfunction (OR=6.65, 95% CI 1.24 to 35.6), lymphopenia (OR=5.76, 95% CI 1.36 to 24.4), Systemic Lupus Erythematosus Activity Index ≥ 6 points (OR=1.11, 95% CI 1.01 to 1.22) and younger age (OR=0.86, 95% CI 0.81 to 0.91, p<0.001) were independent risk factors for development of PRES in SLE. Furthermore, dyslipidemia also characterised the association between PRES and SLE (OR=10.6, 95% CI 1.17 to 96.4).

CONCLUSIONS

This is the largest reported series of patients with SLE and PRES. We were able to corroborate the known risk factors for of PRES, and found two previously undescribed factors (lymphopenia and dyslipidemia), which suggests that endothelial dysfunction is a key element in PRES pathogenesis in lupus patients.

Effect of glycemic and lipid achievements on clinical outcomes type 2 diabetic, Chinese patients with stable coronary artery disease

AIMS

To describe the effect of glycemic and lipid achievements and their joint roles in future major adverse cardiovascular events (MACEs) prediction.

METHODS

One thousand two hundred sixty consecutive, type 2 diabetic patients with stable coronary artery disease (CAD) were identified, they were followed up a median of 24.07months.

RESULTS

At baseline, 85.4% of patients with blood pressure less than 140/90mmHg, while only a minority of patients met guideline-recommended hemoglobin A1C (HbA1C) (44.2%), low-density lipoprotein cholesterol (LDL-C) (24.7%), non high-density lipoprotein cholesterol (NHDL-C) (36.3%), or apolipoprotein B (apoB) levels (38.6%). After follow-up, patients achieving either glycemic or lipid goals experienced a lower rate of future events (HbA1C 35.4%, LDL-C 19.3%, NHDL-C 30.4%, apoB 26.7%). Dual-goal achievements of HbA1C and lipids showed the lowest event risk (adjusted relative risk, RR: HbA1C, 0.92 vs. LDL-C 0.75 vs. dual 0.27; HbA1C, 0.86 vs. NHDL-C 0.59 vs. dual 0.44; HbA1C, 0.74 vs. apoB 0.64 vs. dual 0.55). Patients with suboptimal goals (LDL-C 1.8-2.5mmol/L, NHDL-C 2.5-3.4mmol/L, or apoB 0.8-1.0g/L) were at risk when compared to those with guideline-recommended goals.

CONCLUSIONS

Dual-achievement of glycemic and lipid goals based on a relative well-controlled condition of blood pressure conferred a better prognosis in type 2 diabetic patients with CAD.

Prescription Practice for Diabetes Management among a Female Population in Primary Health Care

Introduction. Prescription for diabetes care is an important practice in primary care. Methods. This is a descriptive study carried out on at primary care clinics over a five-month period at Al Imam Medical Complex, Riyadh, Saudi Arabia. It was cross-sectional study of 160 female diabetic patients, who visited the services between January and May, 2012. Data were collected from the medical records on the clinical characteristics and drugs prescribed for their diabetic management. Results. The majority of the sample population (82%) was older than 40 years old. Half of them had concomitant hypertension, hyperlipidemia, and obesity. There were 500 prescriptions for diabetes management. More than 57% of participants were on two or more drugs for hyperglycemia. Metformin was the most common drug prescribed. Metformin and sulphonylurea were the most common combined medications. Most of cases ( 70%) were on a combination of antihypertensive drugs. ACE or ARBs and diuretic was the most common combined prescriptions. Statins and aspirin were used by 41% and 23.8% of the research population, respectively. Conclusion. Polypharmacy is a feature in diabetes care. Most of the prescription practice for diabetic care follows the recommended guidelines for hyperglycemia and hypertension. Management of dyslipidemia among diabetic patients, however, is an area that needs to be developed.

Lipid control in patients with diabetes mellitus

Patients with diabetes mellitus are at increased risk of cardiovascular disease (CVD). Dyslipidemia, an important component of the insulin resistance syndrome and type 2 diabetes, is strongly related to CVD risk and is open to therapeutic intervention. Statins have proved to be safe, very-well tolerated, and highly effective in reducing the levels of LDL cholesterol and apolipoprotein B. Primary and secondary CVD prevention trials have shown that use of statins leads to highly significant reductions in the incidence of major CVD events. A wealth of data on the outcomes of statin therapy is now available to guide clinical practice in the population of patients with type 2 diabetes. Statin therapy in patients with type 1 diabetes seems to have a similar benefit to that seen in patients with type 2 diabetes. However, despite statin therapy, high CVD risk persists in these populations. More-intensive statin therapy produces greater reduction in the incidence of CVD events, but a more-global approach to lipid management is likely to result in further risk reduction. After reductions in the levels of LDL cholesterol and apolipoprotein B, the next target of lipid-lowering therapy is to increase HDL-cholesterol levels, which tend to be low in patients with type 2 diabetes. The most effective HDL-cholesterol-raising agent currently available for use in clinical practice is niacin. Trials with surrogate end points have pointed to the cardiovascular benefit of adding niacin to statin therapy. Large CVD end point trials, which include many patients with diabetes, are underway to test the combination of a statin and niacin versus a statin alone.

Comparison of the CKD Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD) study equations: prevalence of and risk factors for diabetes mellitus in CKD in the Kidney Early Evaluation Program (KEEP)

BACKGROUND

Diabetes is a leading cause of chronic kidney disease (CKD). Whether reclassification of CKD stages based on glomerular filtration rate estimated using the CKD Epidemiology Collaboration (CKD-EPI) equation versus the Modification of Diet in Renal Disease (MDRD) Study equation modifies estimates of prevalent risk factors across stages is unknown.

METHODS

This is a cross-sectional analysis of data from the Kidney Early Evaluation Program (KEEP), a community-based health screening program targeting individuals 18 years and older with diabetes, hypertension, or a family history of diabetes, hypertension, or kidney disease. Of 109,055 participants, 68.2% were women and 31.8% were African American. Mean age was 55.3 ± 0.05 years. Clinical, demographic, and laboratory data were collected from August 2000 through December 2009. Glomerular filtration rate was estimated using the CKD-EPI and MDRD Study equations.

RESULTS

CKD was present in 25.6% and 23.5% of the study population using the MDRD Study and CKD-EPI equations, respectively. Diabetes was present in 42.4% and 43.8% of participants with CKD, respectively. Prevalent risk factors for diabetes included obesity (body mass index >30 kg/m(2)), 44.0%; hypertension, 80.5%; cardiovascular disease, 23.2%; family history of diabetes, 55.9%; and dyslipidemia, 43.0%. In a logistic regression model after adjusting for age and other risk factors, odds for diabetes increased significantly compared with no CKD with each CKD stage based on the CKD-EPI equation and similarly with stages based on the MDRD Study equation. Using a CKD-EPI-adjusted model, ORs were: stage 1, 2.08 (95% CI, 1.90-2.27); stage 2, 1.86 (95% CI, 1.72-2.02); stage 3, 1.23 (95% CI, 1.17-1.30); stage 4, 1.69 (95% CI, 1.42-2.03); and stage 5, 2.46 (95% CI, 1.46-4.14).

CONCLUSIONS

Using the CKD-EPI equation led to a lower prevalence of CKD but to similar diabetes prevalence rates associated with CKD across all stages compared with the MDRD Study equation. Diabetes and other CKD risk factor prevalence was increased compared with the non-CKD population.
