Abstract
BACKGROUND Diabetes Mellitus (DM) is a prominent health care issue worldwide. One of the most prevalent comorbidities of DM is cardiovascular disease (CVD). The objective of this study was to assess the utilization patterns of cardiovascular medications in patients with DM in Iran from 2013 to 2017. METHODS This retrospective cross-sectional study was undertaken using prescription claims data from 2013 to 2017 in Iran. Epidemiological data elements used in this study were obtained from the Global Burden of Disease (GBD) 2019 study. In addition, data on total medication sales were obtained from the national regulatory authority database. The data on medication utilization were analyzed according to the Anatomical Therapeutic Chemical Classification (ATC) /Defined Daily Doses (DDD) international system. RESULTS Based on the findings, Acetylsalicylic acid was the mainstay of treatment with a utilization rate of 191.7 DDD/ patient/ year in 2017, followed by Atorvastatin with 170.0 and Losartan with 115.1. Although there was an increasing trend in the utilization rate of the medications, the rate of Atenolol and Enalapril was constantly declining during the 2013-17 period. On the other hand, Valsartan and Metoprolol were attracting attention. Almost all medication utilization rates increased from the 30-39 age group up to the 80 + age group. Females had a higher utilization rate in each age group during the whole study period. CONCLUSION The present study reflects that medication utilization patterns were rational, according to the standard treatment guidelines. Utilization patterns of medications that are recommended for both prevention and treatment of CVD in diabetes were observed to be the highest. Implementation of further policies is needed to minimize cardiovascular complications of diabetes.

Abstract
The role of the renin angiotensin aldosterone system (RAAS) in the pathophysiology of hypertension, cardiovascular disease and kidney disease has been known for years. RAAS inhibitors have been the mainstay of chronic kidney disease (CKD) treatment. Studies have shown that therapy with angiotensin-converting enzyme inhibitors (ACE inhibitors) or angiotensinII receptor blockers (ARBs) reduce the excretion of albuminuria and slow the progression of kidney disease in patients with and without diabetes. In clinical practice, RAAS inhibitors are recommended as the antihypertensive of choice in patients with CKD and albuminuria with or without diabetes. In addition, they have demonstrated cardiovascular benefits beyond blood pressure control. The use of RAAS inhibitors in non-proteinuric nephropathy and advanced CKD is not without controversy. Double blockade of the RAAS is contraindicated. On the other hand, it is essential to know how to titrate doses and avoid side effects, mainly hyperkalaemia.

Abstract
The classic description of diabetic kidney disease (DKD) involves progressive stages of glomerular hyperfiltration, microalbuminuria, proteinuria, and a decline in the estimated glomerular filtration rate (eGFR), leading to dialysis. In recent years, this concept has been increasingly challenged as evidence suggests that DKD presents more heterogeneously. Large studies have revealed that eGFR decline may also occur independently from the development of albuminuria. This concept led to the identification of a new DKD phenotype: non-albuminuric DKD (eGFR < 60 mL/min/1.73 m2, absence of albuminuria), whose pathogenesis is still unknown. However, various hypotheses have been formulated, the most likely of which is the acute kidney injury-to-chronic kidney disease (CKD) transition, with prevalent tubular, rather than glomerular, damage (typically described in albuminuric DKD). Moreover, it is still debated which phenotype is associated with a higher cardiovascular risk, due to contrasting results available in the literature. Finally, much evidence has accumulated on the various classes of drugs with beneficial effects on DKD; however, there is a lack of studies analyzing the different effects of drugs on the various phenotypes of DKD. For this reason, there are still no specific guidelines for therapy in one phenotype rather than the other, generically referring to diabetic patients with CKD.

Abstract
INTRODUCTION People with type 2 diabetes mellitus (T2DM) and diabetic kidney disease (DKD) have increased morbidity and mortality risk. Angiotensin-converting enzyme inhibitors (ACEi) or angiotensin II receptor blockers (ARB) are recommended to slow kidney function decline in DKD. This representative, real-world data analysis of patients with T2DM was performed to detect onset of DKD and determine methods and timing of DKD diagnosis and time to initiation of ACEi/ARB therapy. METHODS Patients diagnosed with T2DM before January 1, 2016 who developed DKD between January 1, 2017 and June 30, 2019 were identified from a longitudinal ambulatory electronic health record (EHR) dataset (Veradigm Inc). Each record was analyzed using the CLinical INTelligence engine (CLINT™, HealthPals, Inc.) to identify delays and gaps in diagnosing DKD. DKD was diagnosed through two reduced estimated glomerular filtration rate (eGFR; < 60 mL/min/1.73 m2) measurements at least 90 days apart, a single elevated urine albumin-to-creatinine ratio (UACR; > 30 mg/g) measurement, or ICD-9/10 diagnosis codes for DKD and/or albuminuria. Time to diagnose (TTD), time to treat (TTT), and diagnosis to treatment time were assessed. RESULTS Of 6,499,409 patients with T2DM before January 2016, 245,978 developed DKD between January 1, 2017 and June 30, 2019. In this DKD cohort, ca. 50% were first identified through EHR diagnosis and ca. 50% by UACR or eGFR lab-based diagnosis. In patients who had UACR/eGFR assessed, more than 90% exhibited DKD-level results on the first diagnostic test. Average TTD after eGFR labs was 2 years; average TTT with ACEi/ARB was 6-9 months after DKD lab evidence. The majority of patients who developed DKD received ACEi/ARB therapy 6-7 months after diagnosis. CONCLUSION In a contemporary, large national cohort of patients with T2DM, progression to DKD was common but likely underrepresented. The low rate of DKD-screening labs, along with sizable delays in diagnosis of DKD and initiation of ACEi/ARB therapy, indicates that many patients who progress to DKD are not being properly treated.

Abstract
Diabetic retinal disease (DRD) remains the most common cause of vision loss in adults of working age. Progress on the development of new therapies for DRD has been limited by the complexity of the human eye, which constrains the utility of traditional research techniques, including animal and tissue culture models-a problem shared by those in the field of kidney disease research. By contrast, significant progress in the study of diabetic kidney disease (DKD) has resulted from the successful employment of systems biology approaches. Systems biology is widely used to comprehensively understand complex human diseases through the unbiased integration of genetic, environmental, and phenotypic aspects of the disease with the functional and structural manifestations of the disease. The application of a systems biology approach to DRD may help to clarify the molecular basis of the disease and its progression. Acquiring this type of information might enable the development of personalized treatment approaches, with the goal of discovering new therapies targeted to an individual's specific DRD pathophysiology and phenotype. Furthermore, recent efforts have revealed shared and distinct pathways and molecular targets of DRD and DKD, highlighting the complex pathophysiology of these diseases and raising the possibility of therapeutics beneficial to both organs. The objective of this review is to survey the current understanding of DRD pathophysiology and to demonstrate the investigative approaches currently applied to DKD that could promote a more thorough understanding of the structure, function, and progression of DRD.

Abstract
BACKGROUND AND AIMS A decrease in high-density lipoprotein (HDL)-cholesterol concentrations during transgender hormone therapy has been shown. However, the ability of HDL to remove cholesterol from arterial wall macrophages, termed cholesterol efflux capacity (CEC), has proven to be a better predictor of cardiovascular disease (CVD) largely independently of HDL-concentrations. In addition, the serum capacity to load macrophages with cholesterol (cholesterol loading capacity, CLC) represents an index of pro-atherogenic potential. As transgender individuals are exposed to lifelong exogenous hormone therapy (HT), it becomes of interest to study whether HDL-CEC and serum CLC are affected by HT. HDL-CEC and serum CLC have been evaluated in 15 trans men treated with testosterone and in 15 trans women treated with estradiol and cyproterone acetate at baseline and after 12 months of HT. METHODS Total HDL-CEC from macrophages and its major contributors, the ATP-binding cassette transporters (ABC) A1 and ABCG1 HDL-CEC and HDL-CEC by aqueous diffusion were determined by a radioisotopic assay. CLC was evaluated in human THP-1 macrophages. RESULTS In trans women, total HDL-CEC decreased by 10.8% (95%CI: -14.3;-7.3; p < 0.001), ABCA1 HDL-CEC by 23.8% (-34.7; -12.9; p < 0.001) and aqueous diffusion HDL-CEC by 4.8% (-8.4;-1.1; p < 0.01). In trans men, only aqueous diffusion HDL-CEC decreased significantly, -9.8% (-15.7;-3.9; p < 0.01). ABCG1 HDL-CEC did not change in either group. Serum CLC and HDL subclass distribution were not modified by HT in both groups. CONCLUSIONS Total HDL-CEC decreased during HT in trans women, with a specific reduction in ABCA1 CEC. This finding might contribute to a higher CVD risk.

Abstract
AIM To assess the impact of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers on renal and mortality outcomes in people with Type 2 diabetes and proteinuria. METHODS A literature search up to 6 June 2019 was performed. We included randomized trials of ≥100 participants with Type 2 diabetes and micro- or macroalbuminuria comparing an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker with placebo ± background anti-hypertensives or non-angiotensin-converting enzyme inhibitor or angiotensin receptor blocker-containing anti-hypertensives, which included follow-up of ≥12 months. Endpoints included doubling of serum creatinine, end-stage renal disease, all-cause and cardiovascular mortality and progression and regression of proteinuria. A Hartung-Knapp random-effects model (between-study variance calculated using the Paule-Mandel estimator) producing a risk ratio with 95% confidence interval was employed. RESULTS The use of an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker was not associated with a significant reduction in the risk of a doubling in serum creatinine (n = 7 trials, RR = 0.77, 95% CI = 0.50-1.21). Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers reduced the risk of progressing to end-stage renal disease (n = 8, RR = 0.79, 95% CI = 0.75-0.83). No difference in all-cause (n = 11, RR = 0.98, 95% CI = 0.89-1.08) or cardiovascular mortality (n = 6 trials, RR = 1.08, 95% CI = 0.92-1.28), nor the composite outcome of doubling in serum creatinine, end-stage renal disease or mortality (n = 3 trials, RR = 0.87, 95% CI = 0.72-1.06), was observed. Progression of proteinuria was decreased with angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use vs. control (n = 10, RR = 0.49, 95% CI = 0.33-0.74). Regression of proteinuria was not improved with an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker (n = 11, RR = 1.55, 95% CI = 0.93-2.58). CONCLUSION Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers may reduce the risk of end-stage renal disease and slow the progression of nephropathy, but they do not appear to decrease all-cause or cardiovascular mortality in people with Type 2 diabetes and proteinuria.

Abstract
BACKGROUND/AIMS The association of diastolic blood pressure (DBP) with incidence of chronic kidney disease (CKD) in the general population is not well examined. METHODS Using national health check-up database from 2008 to 2011 in the general Japanese population aged 39-74 years, we evaluated the association between DBP and incidence of CKD 2 years later in 127,954 participants without CKD. DBP was categorized by every 5 mm Hg from the lowest (<60 mm Hg) to the highest category (>100 mm Hg) and was further stratified into those with and without antihypertensive medications (BP meds). We calculated the OR for estimating adjusted risk of incident CKD using logistic regression model. RESULTS Participants were 62% female and 25.9% with BP meds, mean age of 76 years with estimated glomerular filtration rate of 78.2 ± 13.4 and DBP of 76 ± 11 mm Hg. Two years later, 12,379 (9.7%) developed CKD. Compared to DBP 60-64 mm Hg without BP meds as reference, multivariate analysis showed no difference in CKD risk at any DBP category among those without BP meds. However, in those with BP meds, risk increased according to lower DBP from 95 to 60 mm Hg (p for trend 0.05) with OR 1.51 (95% CI 1.14-1.99) in DBP <60 mm Hg. In subgroup analysis within those with or without BP meds, CKD risk was lower at higher DBP (p for trend 0.02) only in those without BP meds. CONCLUSION Lower DBP was associated with higher risk of incident CKD only in the general population taking antihypertensive medication.

Abstract
Chronic kidney disease (CKD) is a growing public health issue worldwide. It is acknowledged that CKD is associated with increased risk of cardiovascular disease, which is the leading cause of morbidity and mortality in this population. The role of the renin-angiotensin-aldosterone system in the pathophysiology of hypertension, and cardiovascular and kidney diseases is well known and the renin-angiotensin-aldosterone system is a major regulator of blood pressure through its effect on body fluids and electrolyte homeostasis. For 2 decades, renin-angiotensin system inhibitors have been the mainstay of treatment for CKD. Clinical trials have shown that prescription of monotherapy with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers reduces albuminuria and slows the progression of nephropathy in patients with diabetes. In clinical practice guidelines, renin-angiotensin system inhibitors are recommended as the antihypertensive drug of choice in patients with CKD with or without diabetes. Moreover, renin-angiotensin system inhibitors have been shown to offer cardiovascular protection beyond those resulting after blood pressure control. However, the benefits of renin-angiotensin system inhibitor prescriptions for patients with advanced CKD remain controversial. Patients with advanced CKD or who undergo dialysis are under-represented in clinical trials, and studies in this population are urgently needed.

Abstract
OBJECTIVE Clinicopathological characteristics, renal prognosis, and mortality in patients with type 2 diabetes and reduced renal function without overt proteinuria are scarce. RESEARCH DESIGN AND METHODS We retrospectively assessed 526 patients with type 2 diabetes and reduced renal function (estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m2), who underwent clinical renal biopsy and had follow-up data, from Japan's nationwide multicenter renal biopsy registry. For comparative analyses, we derived one-to-two cohorts of those without proteinuria versus those with proteinuria using propensity score-matching methods addressing the imbalances of age, sex, diabetes duration, and baseline eGFR. The primary end point was progression of chronic kidney disease (CKD) defined as new-onset end-stage renal disease, decrease of eGFR by ≥50%, or doubling of serum creatinine. The secondary end point was all-cause mortality. RESULTS Eighty-two patients with nonproteinuria (urine albumin-to-creatinine ratio [UACR] <300 mg/g) had lower systolic blood pressure and less severe pathological lesions compared with 164 propensity score-matched patients with proteinuria (UACR ≥300 mg/g). After a median follow-up of 1.9 years (interquartile range 0.9-5.0 years) from the date of renal biopsy, the 5-year CKD progression-free survival was 86.6% (95% CI 72.5-93.8) for the nonproteinuric group and 30.3% (95% CI 22.4-38.6) for the proteinuric group (log-rank test P < 0.001). The lower renal risk was consistent across all subgroup analyses. The all-cause mortality was also lower in the nonproteinuric group (log-rank test P = 0.005). CONCLUSIONS Patients with nonproteinuric diabetic kidney disease had better-controlled blood pressure and fewer typical morphological changes and were at lower risk of CKD progression and all-cause mortality.

Abstract
BACKGROUND This is the first update of a Cochrane Review first published in 2015. Renin angiotensin system (RAS) inhibitors include angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs) and renin inhibitors. They are widely prescribed for treatment of hypertension, especially for people with diabetes because of postulated advantages for reducing diabetic nephropathy and cardiovascular morbidity and mortality. Despite widespread use for hypertension, the efficacy and safety of RAS inhibitors compared to other antihypertensive drug classes remains unclear. OBJECTIVES To evaluate the benefits and harms of first-line RAS inhibitors compared to other first-line antihypertensive drugs in people with hypertension. SEARCH METHODS The Cochrane Hypertension Group Information Specialist searched the following databases for randomized controlled trials up to November 2017: the Cochrane Hypertension Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (from 1946), Embase (from 1974), the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. We also contacted authors of relevant papers regarding further published and unpublished work. The searches had no language restrictions. SELECTION CRITERIA We included randomized, active-controlled, double-blinded studies (RCTs) with at least six months follow-up in people with elevated blood pressure (≥ 130/85 mmHg), which compared first-line RAS inhibitors with other first-line antihypertensive drug classes and reported morbidity and mortality or blood pressure outcomes. We excluded people with proven secondary hypertension. DATA COLLECTION AND ANALYSIS Two authors independently selected the included trials, evaluated the risks of bias and entered the data for analysis. MAIN RESULTS This update includes three new RCTs, totaling 45 in all, involving 66,625 participants, with a mean age of 66 years. Much of the evidence for our key outcomes is dominated by a small number of large RCTs at low risk for most sources of bias. Imbalances in the added second-line antihypertensive drugs in some of the studies were important enough for us to downgrade the quality of the evidence.Primary outcomes were all-cause death, fatal and non-fatal stroke, fatal and non-fatal myocardial infarction (MI), fatal and non-fatal congestive heart failure (CHF) requiring hospitalizations, total cardiovascular (CV) events (fatal and non-fatal stroke, fatal and non-fatal MI and fatal and non-fatal CHF requiring hospitalization), and end-stage renal failure (ESRF). Secondary outcomes were systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR).Compared with first-line calcium channel blockers (CCBs), we found moderate-certainty evidence that first-line RAS inhibitors decreased heart failure (HF) (35,143 participants in 5 RCTs, risk ratio (RR) 0.83, 95% confidence interval (CI) 0.77 to 0.90, absolute risk reduction (ARR) 1.2%), and that they increased stroke (34,673 participants in 4 RCTs, RR 1.19, 95% CI 1.08 to 1.32, absolute risk increase (ARI) 0.7%). Moderate-certainty evidence showed that first-line RAS inhibitors and first-line CCBs did not differ for all-cause death (35,226 participants in 5 RCTs, RR 1.03, 95% CI 0.98 to 1.09); total CV events (35,223 participants in 6 RCTs, RR 0.98, 95% CI 0.93 to 1.02); and total MI (35,043 participants in 5 RCTs, RR 1.01, 95% CI 0.93 to 1.09). Low-certainty evidence suggests they did not differ for ESRF (19,551 participants in 4 RCTs, RR 0.88, 95% CI 0.74 to 1.05).Compared with first-line thiazides, we found moderate-certainty evidence that first-line RAS inhibitors increased HF (24,309 participants in 1 RCT, RR 1.19, 95% CI 1.07 to 1.31, ARI 1.0%), and increased stroke (24,309 participants in 1 RCT, RR 1.14, 95% CI 1.02 to 1.28, ARI 0.6%). Moderate-certainty evidence showed that first-line RAS inhibitors and first-line thiazides did not differ for all-cause death (24,309 participants in 1 RCT, RR 1.00, 95% CI 0.94 to 1.07); total CV events (24,379 participants in 2 RCTs, RR 1.05, 95% CI 1.00 to 1.11); and total MI (24,379 participants in 2 RCTs, RR 0.93, 95% CI 0.86 to 1.01). Low-certainty evidence suggests they did not differ for ESRF (24,309 participants in 1 RCT, RR 1.10, 95% CI 0.88 to 1.37).Compared with first-line beta-blockers, low-certainty evidence suggests that first-line RAS inhibitors decreased total CV events (9239 participants in 2 RCTs, RR 0.88, 95% CI 0.80 to 0.98, ARR 1.7%), and decreased stroke (9193 participants in 1 RCT, RR 0.75, 95% CI 0.63 to 0.88, ARR 1.7% ). Low-certainty evidence suggests that first-line RAS inhibitors and first-line beta-blockers did not differ for all-cause death (9193 participants in 1 RCT, RR 0.89, 95% CI 0.78 to 1.01); HF (9193 participants in 1 RCT, RR 0.95, 95% CI 0.76 to 1.18); and total MI (9239 participants in 2 RCTs, RR 1.05, 95% CI 0.86 to 1.27).Blood pressure comparisons between first-line RAS inhibitors and other first-line classes showed either no differences or small differences that did not necessarily correlate with the differences in the morbidity outcomes.There is no information about non-fatal serious adverse events, as none of the trials reported this outcome. AUTHORS' CONCLUSIONS All-cause death is similar for first-line RAS inhibitors and first-line CCBs, thiazides and beta-blockers. There are, however, differences for some morbidity outcomes. First-line thiazides caused less HF and stroke than first-line RAS inhibitors. First-line CCBs increased HF but decreased stroke compared to first-line RAS inhibitors. The magnitude of the increase in HF exceeded the decrease in stroke. Low-quality evidence suggests that first-line RAS inhibitors reduced stroke and total CV events compared to first-line beta-blockers. The small differences in effect on blood pressure between the different classes of drugs did not correlate with the differences in the morbidity outcomes.

Abstract
A number of large randomised controlled trials have shown that angiotensin-converting enzyme (ACE) inhibitors, compared with placebo or other blood pressure-lowering drugs, improve coronary heart disease outcomes (fatal and non-fatal myocardial infarction, and coronary revascularisation) in diverse patient groups, e.g. in primary and secondary prevention, those with and without left ventricular dysfunction, and among hypertensive and non-hypertensive subjects. An updated meta-regression analysis which included five major trials in patients with established coronary artery disease (CAD) (EUROPA, INVEST, ACTION, PEACE and CAMELOT) concluded that ACE inhibitor (ACE-I) therapy has clear benefits in secondary prevention, but there are important and unexplained differences between trials in clinical outcome, baseline cardiovascular risk, blood pressure changes and trial design which deserve further discussion of the underlying mechanisms and clinical interpretation. For example, in placebo-controlled trials the biggest (20—22%) reductions in primary end points (including mortality) have been observed with perindopril and ramipril, whereas trials using trandolapril and quinapril had no effect on survival or recurrent CAD events. This review summarises and compares the major findings of these recent trials, and provides further analysis of the underlying mechanisms and clinical significance of secondary CAD prevention with ACE-I therapy.

Abstract
Background. The renin-angiotensin system (RAS) has been considered to be responsible for the pathogenesis or progression of many diseases which may or may not be related to kidney. Genetic polymorphisms of the various components of the RAS have been associated with differences in the clinical course of several disease states in adults and children.Objectives. The purpose of our study was to investigate RAS gene polymorphisms in patients with steroid resistant primary focal segmental glomerulosclerosis (FSGS) and nephrotic syndrome responding to steroid therapy. Furthermore, we aimed to investigate whether there was an association between polymorphic alleles and responses to steroid therapy, the degree of renal dysfunction, and prevalence of end-stage renal disease (ESRD).Material and methods. One hundred and fifty-eight children with the diagnosis of nephrotic syndrome were recruited from the Nephrology unit in the Department of Paediatrics of Ege University. Forty-nine of them were classified as renal biopsy-proven FSGS and 102 patients were considered to have response to steroid treatment. Renal functional impairment was detected in 19 subjects with FSGS and end-stage renal insufficiency in 13 patients. The control group consisted of 287 healthy adult subjects. Angiotensin-converting enzyme (ACE), angiotensin II type 1 receptor (AT1R) and angiotensinogen (AGT) gene polymorphisms were determined by the polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) technique. Statistical significance was regarded as p<0.05.Results. There were no statistically significant differences for the C allele of AT1R or the T allele of AGT genes between the children with nephrotic syndrome and control group, but on the other hand statistically significant differences were detected for D allele of ACE gene. There was no significant relationship detected between the D allele of ACE, the C allele of AT1R or the T allele of AGT genes and response to steroid therapy, extent of renal dysfunction and the progression to ESRD. However, there was a significant relationship between T allele of AGT gene and resistance to steroid treatment (OR; 4,837, 95% CI; 1,723—13,577, p=0.01), renal dysfunction (OR; 3,189, 95% CI; 0,999—10,182, p=0.041) and progression to ESRD (OR; 3,852, 95% CI; 1,057—14,040, p=0.03).Conclusion. In this study, the angiotensino gene -235T allele was found to be related with steroid resistance, renal dysfunction and progression of ESRD in nephrotic syndrome.

Abstract
Current guidelines recommend renin angiotensin system inhibitors (RASI) as key components of treatment of hypertension in patients with chronic kidney disease (CKD), because of their effect on reducing the future rate of loss of glomerular filtration rate (GFR). A common risk of RASI in CKD is a haemodynamically mediated, and reversible, fall in GFR of varying severity and duration, any time after commencement of the Inhibitors. A benefit of the acute reduction in filtration rate with RASI may be a reduction in the future rate of loss in GFR: the greatest benefit likely to be in those patients with a greater rate of loss of GFR prior to, and a lesser acute loss of GFR after, introduction of RASI; and in those patients with significant proteinuria. An acute loss of GFR of >25% following the introduction of RASI is an indication to cease the RASI. An acute loss of GFR < 25% requires consideration of the likely risks of the lower GFR and benefits of any future reduced rate of loss of GFR. A fall in GFR in patients while on RASI is usually associated with a remediable cause. When the cause for the fall in GFR is not revealed, and the fall is less than 25%, hopeful expectancy is recommended. Hyperkalaemia in patients with CKD on RASI is more common with more severe disease, potassium retaining diuretics and hypoaldosteronism. Treatment should be modified to maintain a plasma potassium <6 mmol/L.

Abstract
BACKGROUND The renoprotective effect of inhibitors of renin-angiotensin system (RAS) has been identified through placebo-controlled trials. However, the effect of calcium-channel blockers (CCBs) on renal system is still controversial. Our current meta-analysis includes available evidences to compare the effect of dihydropyridine CCBs and ACEIs or ARBs on renal outcomes and mortality. We also further investigate whether CCBs can be used in combination with inhibitors of RAS to improve the prognosis of patients with chronic kidney disease (CKD). METHODS AND RESULTS Electronic databases were searched up to July 2012, for clinical randomized controlled trials, assessing the effect of dihydropyridine CCBs on the incidence of end-stage renal disease (ESRD) and all-cause mortality in contrast to ACEIs or ARBs. Eight clinical trials were included containing 25,647 participants. ESRD showed significantly higher frequency with CCBs therapy compared with ACEIs or ARBs therapy, though blood pressure was decreased similarly in both groups in every trial (OR, 1.25; 95% CI, 1.05-1.48; p = 0.01). In contrast, there was no significant difference in the incidence of all-cause mortality between these two groups, though ACEIs or ARBs exhibited better renoprotective effect compared to CCBs (OR, 0.96; 95% CI, 0.89-1.03; p = 0.24). CONCLUSIONS CCBs did not increase all-cause mortality incidence in patients with CKD though they displayed weaker renoprotective, compared to ACEIs or ARBs therapy. Our results suggest the combination of a CCB and an ACEI or ARB should be a preferable antihypertensive therapy in patients with CKD, considering their higher effect in decreasing blood pressure and fewer adverse metabolic problems caused.

Abstract
Objective: Till date, several studies have compared angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) in terms of delaying the progression of diabetic nephropathy. But the superiority of one drug class over the other remains unsettled. This study has retrospectively compared the effects of ACE inhibitors and ARBs in diabetic nephropathy. The study aims to compare ACE inhibitors and ARBs in terms of delaying or preventing the progression of diabetic nephropathy, association between blood pressure (B.P) and urinary albumin and also B.P and serum creatinine with ACE inhibitor and ARB, know the percentage of hyperkalemia in patients of diabetic nephropathy receiving ACE inhibitor or ARB. Settings and Design: A total of 134 patients diagnosed with diabetic nephropathy during the years 2001–2010 and having a complete follow-up were studied, out of which 99 were on ARB (63 patients of Losartan and 36 of Telmisartan) and 35 on ACE inhibitor (Ramipril). Subjects and Methods: There was at least 1-month of interval between each observation made and also between the date of treatment started and the first reading that is, the observation of the 1st month. In total, three readings were taken that is, of the 1st, 2nd and 3rd month after the treatment started. Comparison of the 1st and 3rd month after the treatment started was done. Mean ± standard deviation, Paired t-test, and Chi-square were used for the analysis of the data. Results: The results reflect that ARBs (Losartan and Telmisartan) when compared to ACE inhibitor (Ramipril) are more effective in terms of delaying the progression of diabetic nephropathy and also in providing renoprotection. Also, ARBs have the property of simultaneously decreasing the systolic B.P and albuminuria when compared to ACE inhibitor (Ramipril). Conclusions: Angiotensin receptor blockers are more renoprotective than ACE inhibitors and also provide better cardioprotection.

Abstract
Diabetic Kidney Disease (DKD) is the leading cause of chronic kidney disease in developed countries and its prevalence has increased dramatically in the past few decades. These patients are at an increased risk for premature death, cardiovascular disease, and other severe illnesses that result in frequent hospitalizations and increased health-care utilization. Although much progress has been made in slowing the progression of diabetic nephropathy, renal dysfunction and the development of end-stage renal disease remain major concerns in diabetes. Dysregulation of the renin-angiotensin-aldosterone system (RAAS) results in progressive renal damage. RAAS blockade is the cornerstone of treatment of DKD, with proven efficacy in many arenas. The theoretically-attractive option of combining these medications that target different points in the pathway, potentially offering a more complete RAAS blockade, has also been tested in clinical trials, but long-term outcomes were disappointing. This review examines the “state of play” for RAAS blockade in DKD, dual blockade of various combinations, and a perspective on its benefits and potential risks.

Abstract
BACKGROUND Renin-angiotensin system (RAS) inhibitors are widely prescribed for treatment of hypertension, especially for diabetic patients on the basis of postulated advantages for the reduction of diabetic nephropathy and cardiovascular morbidity and mortality. Despite widespread use of angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) for hypertension in both diabetic and non-diabetic patients, the efficacy and safety of RAS inhibitors compared to other antihypertensive drug classes remains unclear. OBJECTIVES To evaluate the benefits and harms of first-line RAS inhibitors compared to other first-line antihypertensive drugs in patients with hypertension. SEARCH METHODS We searched the Cochrane Hypertension Group's Specialised Register, MEDLINE, MEDLINE In-Process, EMBASE and ClinicalTrials.gov for randomized controlled trials up to November 19, 2014 and the Cochrane Central Register of Controlled Trials (CENTRAL) up to October 19, 2014. The WHO International Clinical Trials Registry Platform (ICTRP) is searched for inclusion in the Cochrane Hypertension Group's Specialised Register. SELECTION CRITERIA We included randomized, active-controlled, double-blinded studies with at least six months follow-up in people with primary elevated blood pressure (≥130/85 mmHg), which compared first-line RAS inhibitors with other first-line antihypertensive drug classes and reported morbidity and mortality or blood pressure outcomes. Patients with proven secondary hypertension were excluded. DATA COLLECTION AND ANALYSIS Two authors independently selected the included trials, evaluated the risk of bias and entered the data for analysis. MAIN RESULTS We included 42 studies, involving 65,733 participants, with a mean age of 66 years. Much of the evidence for our key outcomes is dominated by a small number of large studies at a low risk of bias for most sources of bias. Imbalances in the added second-line antihypertensive drugs in some of the studies were important enough for us to downgrade the quality of the evidence.Primary outcomes were all-cause death, fatal and non-fatal stroke, fatal and non-fatal myocardial infarction (MI), fatal and non-fatal congestive heart failure (CHF) requiring hospitalization, total cardiovascular (CV) events (consisted of fatal and non-fatal stroke, fatal and non-fatal MI and fatal and non-fatal CHF requiring hospitalizations), and ESRF. Secondary outcomes were systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR).Compared with first-line calcium channel blockers (CCBs), we found moderate quality evidence that first-line RAS inhibitors decreased heart failure (HF) (35,143 participants in 5 RCTs, RR 0.83, 95% CI 0.77 to 0.90, ARR 1.2%), and moderate quality evidence that they increased stroke (34,673 participants in 4 RCTs, RR 1.19, 95% CI 1.08 to 1.32, ARI 0.7%). They had similar effects on all-cause death (35,226 participants in 5 RCTs, RR 1.03, 95% CI 0.98 to 1.09; moderate quality evidence), total CV events (35,223 participants in 6 RCTs, RR 0.98, 95% CI 0.93 to 1.02; moderate quality evidence), total MI (35,043 participants in 5 RCTs, RR 1.01, 95% CI 0.93 to 1.09; moderate quality evidence). The results for ESRF do not exclude potentially important differences (19,551 participants in 4 RCTs, RR 0.88, 95% CI 0.74 to 1.05; low quality evidence).Compared with first-line thiazides, we found moderate quality evidence that first-line RAS inhibitors increased HF (24,309 participants in 1 RCT, RR 1.19, 95% CI 1.07 to 1.31, ARI 1.0%), and increased stroke (24,309 participants in 1 RCT, RR 1.14, 95% CI 1.02 to 1.28, ARI 0.6%). They had similar effects on all-cause death (24,309 participants in 1 RCT, RR 1.00, 95% CI 0.94 to 1.07; moderate quality evidence), total CV events (24,379 participants in 2 RCTs, RR 1.05, 95% CI 1.00 to 1.11; moderate quality evidence), and total MI (24,379 participants in 2 RCTs, RR 0.93, 95% CI 0.86 to 1.01; moderate quality evidence). Results for ESRF do not exclude potentially important differences (24,309 participants in 1 RCT, RR 1.10, 95% CI 0.88 to 1.37; low quality evidence).Compared with first-line beta-blockers, we found low quality evidence that first-line RAS inhibitors decreased total CV events (9239 participants in 2 RCTs, RR 0.88, 95% CI 0.80 to 0.98, ARR 1.7%), and low quality evidence that they decreased stroke (9193 participants in 1 RCT, RR 0.75, 95% CI 0.63 to 0.88, ARR 1.7% ). Our analyses do not exclude potentially important differences between first-line RAS inhibitors and beta-blockers on all-cause death (9193 participants in 1 RCT, RR 0.89, 95% CI 0.78 to 1.01; low quality evidence), HF (9193 participants in 1 RCT, RR 0.95, 95% CI 0.76 to 1.18; low quality evidence), and total MI (9239 participants in 2 RCTs, RR 1.05, 95% CI 0.86 to 1.27; low quality evidence).Blood pressure comparisons between RAS inhibitors and other classes showed either no differences or small differences that did not necessarily correlate with the differences in the morbidity outcomes.In the protocol, we identified non-fatal serious adverse events (SAE) as a primary outcome. However, when we extracted the data from included studies, none of them reported total SAE in a manner that could be used in the review. Therefore, there is no information about SAE in the review. AUTHORS' CONCLUSIONS We found predominantly moderate quality evidence that all-cause mortality is similar when first-line RAS inhibitors are compared to other first-line antihypertensive agents. First-line thiazides caused less HF and stroke than first-line RAS inhibitors. The quality of the evidence comparing first-line beta-blockers and first-line RAS inhibitors was low and the lower risk of total CV events and stroke seen with RAS inhibitors may change with the publication of additional trials. Compared with first-line CCBs, first-line RAS inhibitors reduced HF but increased stroke. The magnitude of the reduction in HF exceeded the increase in stroke. The small differences in effect on blood pressure between the different classes of drugs did not correlate with the differences in the primary outcomes.

Abstract
BACKGROUND Failure to achieve good blood pressure (BP) control is probably the most important reason for high rates of morbidity and mortality in patients with hypertension. Combination therapy has been shown to increase the percentage of patients in whom BP control is achieved. One combination is a calcium channel blocker (CCB) and an angiotensin-converting enzyme inhibitor (ACE-I). OBJECTIVE The aim of this study was to assess the effects of the fixed combination of the CCB manidipine and the ACE-I delapril in the treatment of hypertensive patients already given monotherapy with either component but with poor results (ie, insufficient BP control or adverse events [AEs]). METHODS In this Phase III, multicenter, open-label, clinical trial, patients with mild to moderate hypertension were assigned to 1 of 2 groups. Group 1 comprised patients whose diastolic BP (DBP) was >90 mm Hg or who experienced AEs with manidipine 20 mg once daily. Group 2 comprised patients who had a DBP >90 mm Hg or who experienced AEs with delapril 30 mg BID. In both groups, patients aged <65 years were to be treated with a fixed combination of manidipine 10 mg plus delapril 30 mg once daily for 12 weeks, whereas patients aged ≥65 years were to be treated with manidipine 5 mg plus delapril 15 mg once daily for 2 weeks and then manidipine 10 mg plus delapril 30 mg once daily for 10 weeks. Patients were assessed at baseline and at 2, 4, 8, and 12 weeks of treatment. At each visit, systolic blood pressure (SBP), DBP, and heart rate were measured 24 hours after dosing, and AEs were recorded. RESULTS Group 1 included 154 patients (80 men, 74 women; mean [SD] age, 55 [6] years); group 2 included 158 patients (79 men, 79 women; mean [SD] age, 56 [5] years). Mean BP decreased significantly in both groups (P<0.01). Compared with baseline values, mean SBP/DBP decreased 16.2 (3.8)/10.1 (1.9) mm Hg in group 1 and 15.8 (3.1)/11.0 (1.5) mm Hg in group 2 at the last visit. The success rate-rate of normalized DBP (≤90 mm Hg) and responder rate (DBP reduction ≥10 mm Hg)-was 79% in group 1 and 82% in group 2. The rates of treatment-related AEs were 11% in group 1 and 8% in group 2. In group 1, heart rate significantly increased from baseline only at 2 weeks (P<0.05); in group 2, at each visit (P<0.05) except at week 12. However, none of these differences were clinically significant. CONCLUSION In this study population of patients whose BP was not adequately controlled by monotherapy, the fixed combination of manidipine 10 mg plus delapril 30 mg, once daily, was effective and well tolerated.

Abstract
OBJECTIVE To determine the association between laboratory-derived measures of glycemic control (HbA1c) and the presence of renal complications (measured by proteinuria and estimated glomerular filtration rate [eGFR]) with the 5-year costs of caring for people with diabetes. RESEARCH DESIGN AND METHODS We estimated the cumulative 5-year cost of caring for people with diabetes using a province-wide cohort of adults with diabetes as of 1 May 2004. Costs included physician visits, hospitalizations, ambulatory care (emergency room visits, day surgery, and day medicine), and drug costs for people >65 years of age. Using linked laboratory and administrative clinical and costing data, we determined the association between baseline glycemic control (HbA1c), proteinuria, and kidney function (eGFR) and 5-year costs, controlling for age, socioeconomic status, duration of diabetes, and comorbid illness. RESULTS We identified 138,662 adults with diabetes. The mean 5-year cost of diabetes in the overall cohort was $26,978 per patient, excluding drug costs. The mean 5-year cost for the subset of people >65 years of age, including drug costs, was $44,511 (Canadian dollars). Cost increased with worsening kidney function, presence of proteinuria, and suboptimal glycemic control (HbA1c >7.9%). Increasing age, Aboriginal status, socioeconomic status, duration of diabetes, and comorbid illness were also associated with increasing cost. CONCLUSIONS The cost of caring for people with diabetes is substantial and is associated with suboptimal glycemic control, abnormal kidney function, and proteinuria. Future studies should assess if improvements in the management of diabetes, assessed with laboratory-derived measurements, result in cost reductions.

Abstract
India leads the world with largest number of diabetics earning the dubious distinction of "the diabetes capital of the world." Diabetes is associated with maternal and perinatal morbidity and mortality. The number of pregnant women with pre-existing diabetes is increasing, mainly from an increase in type 2 diabetes, but also an increase in type 1 diabetes. Overall, type 1 diabetes accounts for approximately 5% to 10% of all diabetes outside of pregnancy, and in pregnancy put together with type 2 account for 10% of diabetic pregnancies. Management of the pregnant diabetic woman is a complex task that ideally begins before conception. Specific attention is required for diabetic pregnancies in different trimesters of pregnancy. Diabetes, especially type 1 diabetes, can be a challenge in pregnancy, but with education, close monitoring, and latest therapeutic modalities, these women can have healthy newborns. Close attention to diet, glycemic control, metabolic stresses, and early diagnosis and monitoring of complications can make pregnancy a successful experience for women with diabetes. A MedLine search was done to review relevant articles in English literature on diabetes and pregnancy, and specific issues related to pregnancy in type 1 diabetes were reviewed.

Abstract
Diabetes mellitus is the leading cause of end stage renal disease and is responsible for more than 40% of all cases in the United States. Current therapy directed at delaying the progression of diabetic nephropathy includes intensive glycemic and optimal blood pressure control, proteinuria/albuminuria reduction, interruption of the renin-angiotensin-aldosterone system through the use of angiotensin converting enzyme inhibitors and angiotensin type-1 receptor blockers, along with dietary modification and cholesterol lowering agents. However, the renal protection provided by these therapeutic modalities is incomplete. More effective approaches are urgently needed. This review highlights the available standard therapeutic approaches to manage progressive diabetic nephropathy, including markers for early diagnosis of diabetic nephropathy. Furthermore, we will discuss emerging strategies such as PPAR-gamma agonists, Endothelin blockers, vitamin D activation and inflammation modulation. Finally, we will summarize the recommendations of these interventions for the primary care practitioner.

Abstract
INTRODUCTION Diabetic nephropathy is a leading cause of chronic kidney disease (CKD) in the UK. These patients are at significantly increased risk of cardiovascular disease and of progression to end-stage renal disease. We review the epidemiology, pathogenesis and natural history of diabetic nephropathy and evaluate the therapeutic options available. SOURCES OF DATA We searched Medline and PubMed for source articles relevant to diabetic nephropathy and CKD. AREAS OF AGREEMENT Early multifactorial intervention including strict blood pressure control, the use of angiotensin-converting enzyme (ACE) inhibitors or angiotensin two-receptor blockers (A2RB's) and good metabolic control attenuates cardiovascular risk and slows the rate of progression of renal disease. AREAS OF CONTROVERSY Current areas of uncertainty include the relative benefits of ACE inhibitors and A2RBs in combination, whether direct renin inhibitors are harmful in patients with diabetes and also the positioning of hypoglycaemic agents as renal function declines. GROWING POINTS What are the appropriate metabolic and blood pressure targets for patients with diabetes? AREAS TIMELY FOR DEVELOPMENT: Therapeutic strategies as kidney function declines.

Abstract
BACKGROUND Previous studies have shown that patients with chronic kidney disease, including those with diabetic nephropathy, are more likely to die of cardiovascular disease than reach end-stage renal disease (ESRD). This analysis was conducted to determine whether ESRD is a more common outcome than cardiovascular death in patients with type 2 diabetic nephropathy, significant proteinuria, and decreased kidney function who were selected for participation in a clinical trial. STUDY DESIGN Retrospective analysis of the DIAMETRIC (Diabetes Mellitus Treatment for Renal Insufficiency Consortium) database derived from 2 prospective randomized controlled clinical trials (IDNT [Irbesartan Diabetic Nephropathy Trial] and RENAAL [Reduction of Endpoints in Non-Insulin-dependent Diabetes With the Angiotensin II Antagonist Losartan]). SETTING & PARTICIPANTS 3,228 adult patients with type 2 diabetic nephropathy from IDNT and RENAAL were combined to establish the DIAMETRIC database. This is the largest global source of clinical information for patients with type 2 diabetic nephropathy who have decreased kidney function and significant proteinuria. INTERVENTION Angiotensin receptor blocker versus non-angiotensin receptor blocker therapy to slow the progression of type 2 diabetic nephropathy (in the prospective trials). OUTCOMES & MEASUREMENTS Incidence rates of ESRD, cardiovascular death, and all-cause mortality. RESULTS Mean follow-up was 2.8 years; 19.5% of patients developed ESRD, approximately 2.5 times the incidence of cardiovascular death and 1.5 times the incidence of all-cause mortality. ESRD was more common than cardiovascular death in all subgroups analyzed with the exception of participants with low levels of albuminuria (albumin excretion <1.0 g/g) and well-preserved levels of kidney function (estimated glomerular filtration rate >45 mL/min/1.73 m(2)) at baseline. LIMITATIONS All participants were included in a prospective clinical trial. CONCLUSIONS Patients with type 2 diabetic nephropathy, characterized by decreased kidney function and significant proteinuria, are more likely to reach ESRD than die during 3 years' mean follow-up. Given the rapidly increasing number of cases of type 2 diabetes worldwide, this has implications for predicting future renal replacement therapy requirements.

Abstract
Type 2 diabetic nephropathy (type 2 DN) patients traditionally develop significant proteinuria prior to the development of renal impairment. However, this clinical paradigm, based on observations prior to the widespread usage of angiotensin-converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARB), has recently been questioned. 2,303 patients enrolled in the Sulodexide Overt Nephropathy Study (OVERT) were analyzed. Prior therapy with ACEi and/or ARB at the time of screening was recorded in 951 patients. 22% of patients had significant renal impairment with a PCR at screening of <500 mg/g. Therapy with ACEi and/or ARB at the time of screening was recorded in 94%, where prior medication data was available. In patients with type 2 DN and advanced renal impairment, levels of proteinuria below that which traditionally defines overt diabetic nephropathy, are found in more than one fifth of patients. We suggest that the high prevalence of ACEi and ARB usage in patients with type 2 DN may be effecting the traditional clinical paradigm of type 2 DN.

Abstract
The prevalence of preexisting diabetes in pregnancy is increasing largely because of an increase in type 2 diabetes. Outcomes of diabetic pregnancies for mother and newborn have improved greatly in recent decades from advances in understanding the disease process, improved education, and new treatment modalities delivered in a team approach. Nausea and vomiting from pregnancy and pregnancy-associated insulin resistance can make glycemic control a challenge. Care of women with preexisting diabetes demands careful monitoring in the preconception, prenatal, and peripartum periods.

Abstract
Activation of the renin-angiotensin-aldosterone system (RAAS) results in vasoconstriction, muscular (vascular and cardiac) hypertrophy and fibrosis. Established arterial stiffness and cardiac dysfunction are key factors contributing to subsequent cardiovascular and renal complications. Blockade of RAAS has been shown to be beneficial in patients with hypertension, acute myocardial infarction, chronic systolic heart failure, stroke and diabetic renal disease. An aggressive approach for more extensive RAAS blockade with combination of two commonly used RAAS blockers [ACE inhibitors (ACEIs) and angiotensin receptor blockers (ARBs)] yielded conflicting results in different patient populations. Combination therapy is also associated with more side effects, in particular hypotension, hyperkalaemia and renal impairment. Recently published ONTARGET study showed ACEI/ARB combination therapy was associated with more adverse effects without any increase in benefit. The Canadian Hypertension Education Program responded with a new warning: 'Do not use ACEI and ARB in combination'. However, the European Society of Cardiology in their updated heart failure treatment guidelines still recommended ACEI/ARB combo as a viable option. This apparent inconsistency among guidelines generates debate as to which approach of RAAS inhibition is the best. The current paper reviews the latest evidence of isolated ACEI or ARB use and their combination in cardiovascular diseases, and makes recommendations for their prescriptions in specific patient populations.

Abstract
OBJECTIVES Type 2 diabetes is the main cause of end-stage renal disease in Europe and the United States. Angiotensin-converting enzyme (ACE) inhibitors slow down the progression of renal disease and, therefore, provide a renal-protective effect. The aim of this study was to assess the most cost-effective time to start an ACE inhibitor (or an angiotensin II receptor blocker in the event of cough) in patients with type 2 diabetes in Germany. METHODS Three strategies were compared: treating all patients at the time of diagnosing type 2 diabetes, screening for microalbuminuria, and screening for macroalbuminuria. A lifetime Markov decision model with simulated 50-year-old patients with newly diagnosed diabetes mellitus was developed using published data on costs and health outcomes and simulating the progression of renal disease. A statutory health insurance perspective was adopted. RESULTS In the base-case analysis, the treat-all strategy is associated with the lowest costs and highest benefit and, therefore, dominates screening both for macroalbuminuria and microalbuminuria. A multivariate sensitivity analysis shows that the probability of savings is 89 percent. CONCLUSIONS Patients with type 2 diabetes should receive an ACE inhibitor immediately after diagnosis if they do not have contraindications. The potential for cost savings would be even larger if the prevention of cardiovascular events were considered.

Abstract
OBJECTIVES To analyse the management of type 2 diabetes mellitus (T2DM) in Greenland in 2008. Study design. Observational and cross-sectional study, including a review of medical records and databases. METHODS Data on adult (> 19 years old) T2DM patients were collected from each primary health care centre in Greenland. Information was collected about age, gender, HbA1c, blood pressure, blood lipids, and from eye, feet and urine examinations from 15 of the 17 health care districts in Greenland, which represent 90% of the whole adult population of Greenland. Three clinics were excluded because of too few patients (only 7). The management of T2DM patients is described and is based on 6 processes and 3 biological indicators. RESULTS The 12 clinics together performed quite well looking at the monitoring of HbA1c (79%), blood pressure (69%) and blood lipids (83%). However, the screening rates were low within 2 years for microalbuminuria (47%), eye (50%) and foot examinations (29%). Great variation in the management of the treatment was observed among the clinics. No clinic achieved all the standards suggested in this paper. Screening for diabetic retinopathy seemed to be implemented, but the records were not fully updated, whereas screening for microalbuminuria and foot examinations clearly were not routine in most clinics. CONCLUSIONS The management of type 2 diabetes mellitus is a major task for the heath care system in Greenland. It is recommended that the implementation of a national strategy based on national guidelines, local diabetes registers and feedback to the clinics get underway as soon as possible.

Abstract
Direct renin inhibitors are the first new class of antihypertensive to emerge since angiotensin II receptor blockers. We discuss their reno- and cardioprotective potential, based on extrapolation from animal models and phase three trials that are currently ongoing. This paper reviews the potential benefits of direct renin inhibitors (DRIs), the only new anti-hypertensive class developed in the last decade, as compared to pre-existing classes of drug inhibiting more downstream, such as Angiotensin Converting Enzyme inhibitors (ACEI), Angiotensin 2 Receptor Blockers (ARBS).

Abstract
Twenty-four hour ambulatory blood pressure monitoring (ABPM) is a valuable tool in the pediatric and adolescent population with type 1 diabetes. It provides useful information not readily available from sporadic clinic blood pressure (BP) measurements and a more reliable estimation of the subject's BP over an extended period of time. Ambulatory blood pressure monitoring is gaining popularity with clinicians and investigators alike. The American Heart Association has recently issued recommendations for the use of ABPM in children and adolescents. We have incorporated ABPM into our adolescent diabetes practice and present useful information for clinicians planning to initiate 24 h ABPM in their clinical practice.

Abstract
Early renal insufficiency (ERI), defined as a calculated or measured glomerular filtration rate (GFR) between 30 and 60 mL/min per 1.73 m2, is present in more than 10% of the adult Australian population. This pernicious condition is frequently unrecognised, progressive and accompanied by multiple associated comorbidities, including hypertension, renal osteodystrophy, anaemia, sleep apnoea, cardiovascular disease, hyperparathyroidism and malnutrition. Several treatments have been suggested to retard GFR decline in ERI, including blood pressure reduction, angiotensin-converting enzyme inhibition, angiotensin receptor antagonism, calcium channel blockade, cholesterol reduction, smoking cessation, erythropoietin therapy, dietary protein restriction, intensive glycaemic control and early intensive multidisciplinary patient education within a renal unit. In addition, specific interventions have been reported to be renoprotective in atherosclerotic renal artery stenosis, diabetic nephropathy, lupus nephritis and certain forms of primary glomerulonephritis. The present paper reviews the available published randomised controlled clinical trials and meta-analyses supporting (or refuting) a role for each of these therapeutic manoeuvres.

Abstract
INTRODUCTION Our objective was to evaluate the effect of blocking the renin-angiotensin system (RAS) on the expression of transforming growth factor-beta 1 (TGF-beta1), platelet derived growth factor-B (PDGF-B), tumour necrosis factor-alpha (TNF-alpha) and vascular endothelial growth factor (VEGF) in diabetic kidney glomeruli. MATERIALS AND METHOD 1) Uninephrectomised streptozotocin induced diabetic rats were treated during eight months with vehicle (CD) or irbesartan (ID). Uninephrectomised non-diabetic rats were used as control group (ND). Protein urinary excretion and morphological renal damage were analysed. Glomerular expression of TGF-beta1, PDGF-B, VEGF and TNF-alpha were evaluated by Western blot and Immunohistochemistry. 2) Isolated glomeruli of diabetic rats were incubated 24-hours in the presence of different doses of irbesartan. Glomerular expression of TGF-beta1, PDGF-B, TNF-alpha and VEGF were determined by Western blot. RESULTS ND and ID presented lower renal injury and proteinuria than CD (p<0.05). Glomerular expression of TGF-beta1, PDGF-B, TNF-alpha and VEGF were similar in ND and ID, but lower than in CD (p<0.05). In addition, in isolated diabetic rat glomeruli, irbesartan reduced the content of all these factors. CONCLUSION Systemic and local administration of irbesartan lowers glomerular expression of TGF-beta1, PDGF-B, VEGF and TNF-alpha. These data suggest that part of the effect of lowering the expression of these growth factors and cytokines is due to a direct blockade of glomerular RAS.

Abstract
Chronic kidney disease (CKD), a major worldwide public-health problem which affects about 10% of the population, has an increased annual incidence rate of about 5-8%. This increased incidence is mainly due to type 2 diabetes and hypertension and the increasing incidence of elderly patients with CKD. Although the progression to end-stage renal failure (ESRF) is mainly based upon the underlying disease, comorbid conditions such as an initial low renal function, severe proteinuria, and high levels of blood pressure also play important roles in the development of ESRF. Since experimental and clinical evidence suggest that angiotensin II plays a central role in the progression of CKD, pharmacological inhibition of the renin-angiotensin-aldosteron system (RAAS) with angiotensin converting enzyme inhibitors or angiotensin II receptor antagonists has been suggested as first-line treatment for hypertension and prevention of ESRF in these patients. Aliskiren, a novel renin inhibitor is also a promising medical intervention. However, independently of the category of the drugs used, low target blood pressure levels seem to be equally or more important for the delay or prevention of CKD. In this review the results of studies with pharmacological inhibition of the RAAS in patients with diabetic and nondiabetic nephropathy is discussed.
