Introduction: Muscle mass may be a better predictor of mortality than BMI in chronic obstructive pulmonary disease (COPD). Serum creatinine depends on muscle mass and renal function; low values may predict higher mortality.
Objective: To determine whether there is an association between low serum creatinine and mortality in severe COPD.
Methods: This is a retrospective study of serum creatinine values at admission and within the last year before admission. Outcomes measured were mortality at 30 days and one year after admission in patients with acute type 2 respiratory failure secondary to COPD, who were admitted over a one-year period to a respiratory ward (N = 130). The statistics were calculated using the chi-squared test.
Results: There appears to be a significant relationship between the one-year pre-admission creatinine values and mortality at one year (p = 0.0003).
Conclusions: The relationship with mortality appears to be stronger with pre-admission creatinine values rather than the admission values and appears to predict the patients at the highest risk of mortality one year after admission.

Clinical presentation, outcomes and risk of relapses of lupus podocytopathy in a multicentre Italian cohort.
J Nephrol
January 2025
Department of Biomedical Sciences, Humanitas University, Via Rita Levi Montalcini 4, Pieve Emanuele, 20072, Milan, Italy.
Background: In an Italian cohort of lupus podocytopathy patients, we aimed to characterize the presenting features, therapy, and outcomes, and explore differences between relapsing and non-relapsing patients.
Methods: We identified 29 patients with lupus podocytopathy from 1994 to 2023 in 11 Italian Nephrology/Rheumatology Units, and divided them into two groups: relapsing and non-relapsing. Given the limited sample size, a p-value ≤ 0.
Puerarin Attenuates Podocyte Damage in Mice With Diabetic Kidney Disease by Modulating the AMPK/Nrf2 Pathway.

Nephrology Department, Jiangxi Provincial Key Research Laboratory of Traditional Chinese Medicine, Key Research Laboratory of Chronic Renal Failure, Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine, Nanchang, Jiangxi 330006, China.
This study aimed to investigate the potential mechanisms of puerarin in alleviating diabetic nephropathy (DKD) in mice. The DKD model was induced by multiple low-dose injections of streptozotocin (STZ) and a high-sugar and high-fat diet in male C57BL/6J mice. After confirming the onset of DKD, mice were given irbesartan, distilled water, or different concentrations of puerarin (40 and 80 mg/kg/d) by gavage for 8 weeks.

Department of Cardiology, Lishui Central Hospital and the Fifth Affiliated Hospital of Wenzhou Medical University, Lishui, China.
Background: The difference between the estimated glomerular filtration rate (eGFR) calculated from cystatin C and creatinine (eGFRdiff) serves as a biomarker of kidney function impairment. However, the role of eGFRdiff in cardiovascular-kidney-metabolic (CKM) health and its impact on mortality in CKM syndrome patients has not yet been studied.
Methods: This study included 3,622 participants from the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2004.
Acute kidney injury and ANCA positivity in a patient treated with glecaprevir/pibrentasvir: a case report.

Department of Pathology, Montefiore Medical Center, Bronx, NY, United States.
Background: Glecaprevir/pibrentasvir is an effective antiviral therapy for hepatitis C virus infection and is generally regarded safe in patients with renal impairment. However, renal complications are a notable, albeit rare, concern.
Case Presentation: We report a case of acute kidney injury in a man in his 50s with chronic hepatitis C virus, chronic obstructive pulmonary disease, morbid obesity, a history of heroin dependence, and untreated type 2 diabetes mellitus.
Prevalence of chronic kidney disease among Chinese adults with diabetes: a nationwide population-based cross-sectional study.

Background: To date, comprehensive data on the distribution of chronic kidney disease (CKD), the most prevalent comorbidity in diabetes, among Chinese adults with diabetes is lacking. Additionally, research gaps exist in understanding the association between CKD and cardiovascular health (CVH), an integrated indicator of lifestyle and metabolic control, within a nationwide sample of Chinese adults with diabetes.
Methods: A nationally community-based cross-sectional survey was conducted in 2018-2020.
