A cross-sectional study was conducted on the prevalence and epidemiology of micro- and macroalbuminuria in diabetic outpatients in Gondar, Ethiopia. Microalbuminuria was defined as a mean urinary albumin concentration of 30-299mg L-1 in morning urine of three consecutive visits. The frequency of micro- and macroalbuminuria was 32% and 15% in IDDM patients and 37% and 20% in NIDDM patients, respectively. When only patients with a duration of more than 5 years were considered, micro- and macroalbuminuria were prevalent in 33% and 23% of IDDM, and 36% and 31% of NIDDM patients, respectively. In multiple regression analysis, urinary albumin levels (log) were significantly associated with systolic blood pressure and duration in IDDM patients even when proteinuric patients were excluded from the analysis. In NIDDM patients duration and diastolic blood pressure were significant predictors of urinary albumin concentrations. In order to delay chronic complications, screening for microalbuminuria by stick-testing in urine should be introduced into routine laboratory practice in developing countries.

Neutrophil gelatinase-associated lipocalin, kidney injury molecule-1, and periostin: Novel urinary biomarkers in diabetic nephropathy.
World J Nephrol
December 2024
Department of Physiology, All India Institute of Medical Sciences-Bibinagar, Hyderabad 508126, Telangana, India.
Background: Globally, diabetic nephropathy (DN) is the primary cause of chronic kidney disease. Currently, renal function is monitored indirectly using measures of serum creatinine, estimated glomerular filtration rate (eGFR), and proteinuria. Novel urinary biomarkers utilized in the early stages of DN have been described; these indicators can be used in the early identification of the disease, which is important for initiating treatment to halt or impediment the advance of diabetic nephropathy.

Article Synopsis
- Type 2 diabetes mellitus (T2DM) is a varied disease, and recent research suggests that new subgroup classifications can help evaluate the risk of diabetic complications, particularly diabetic kidney disease (DKD) in Chinese patients.
- In a study involving 612 Chinese T2DM patients over 3.5 years, researchers used a two-step cluster analysis with five key parameters to categorize patients into four distinct groups based on their diabetes characteristics.
- Findings revealed that certain groups, like the mild insulin resistance diabetes (MIRD) and severe insulin-deficient diabetes (SIDD), had higher risks of kidney disease progression compared to others, emphasizing the importance of these subgroup classifications in managing T2DM complications.
Urinary Nephrin: A Potential Biomarker of Early Glomerular Injury in a Cohort of Pregnant Women Attending Routine Antenatal Care Services.

Glomerular injury may occur during pregnancy as a consequence of systemic disease and pregnancy-related medical complications. While urinary nephrin has been shown to provide early identification of preeclampsia (PE) in high-risk pregnancies, the role of urinary nephrin in determining glomerular injury in pregnant women is yet to be explored. This study aimed to investigate the use of urinary nephrin as a predictor for early glomerular injury in a study conducted at the Townville University Hospital.

J Am Coll Cardiol

Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.
Background: Finerenone has kidney-protective effects in patients with chronic kidney disease with type 2 diabetes, but effects on kidney outcomes in patients with heart failure with and without diabetes and/or chronic kidney disease are not known.
Objectives: The purpose of this study was to examine the effects of finerenone on kidney outcomes in FINEARTS-HF (Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients With Heart Failure), a randomized trial of finerenone vs placebo among patients with heart failure with mildly reduced or preserved ejection fraction.
Methods: We explored the effects of finerenone on the secondary outcome of a sustained ≥50% estimated glomerular filtration rate (eGFR) decline or kidney failure (sustained eGFR decline <15 mL/min/1.
The development and progression of albuminuria in South Asians with type 2 diabetes compared with Western Europeans. Results from the HinDu the Hague diabetes study.

Public Health and Primary Care/ Health campus The Hague, Leiden University Medical Center, The Hague, Netherlands.
Aim: Although South Asians have an increased risk to develop diabetes, data on the difference in development and progression of diabetic nephropathy between ethnic groups are not consistent. The aim of this study was to evaluate possible differences in the development and progression of albuminuria in South Asians and Western Europeans (WE) with type 2 diabetes in a large closed cohort of South Asians with type 2 diabetes.
Methods: Data on 1269 South Asians and 2272 Dutch adults with type 2 diabetes who were treated in our diabetes clinic in 2006 or referred thereafter were extracted from electronic medical records.
