FcgammaRIIa polymorphism in systemic lupus erythematosus

FcgammaRIIs are the most widely distributed of the Fcgamma receptor family and play an important role in the clearance of immune complexes. Evidence that the FcgammaRIIa-R131 allotype is less able to process and clear immune complexes effectively suggests that this may be a disease susceptibility factor for systemic lupus erythematosus (SLE). Data from studies published thus far do not agree on the potential role of FcgammaRIIa polymorphism in the genetics of SLE. Most studies in fact show no evidence for any correlation between polymorphism of FcgammaRIIa and risk for SLE. However, it remains to be determined whether FcgammaRIIa polymorphism may play a critical role in certain groups of patients, especially in those of differing ethnic background. Polymorphism of FcgammaRIIa may also be important in determining disease phenotype, and identification of this influence may have important implications in patient care and in identifying patients for more aggressive therapy.

INTRODUCTION: Diabetic kidney disease (DKD) remains the leading cause of chronic kidney disease. Dysregulation of circulating miRNAs has been reported, suggesting their pathological roles in DKD. This study aimed to investigate differentially expressed miRNAs in the sera of type 2 diabetes mellitus (T2DM) patients with and without albuminuria in a selected Malaysian population.
METHOD: Forty-one T2DM patients on follow-up at a community clinic were divided into normo-(NA), micro-(MIC), and macroalbuminuria (MAC) groups. Differential levels of miRNAs in 12 samples were determined using the pathway-focused (human fibrosis) miScript miRNA qPCR array and was validated in 33 samples, using the miScript custom qPCR array (CMIHS02742) (Qiagen GmbH, Hilden, Germany).
RESULTS: Trends of upregulation of 3 miRNAs in the serum, namely, miR-874-3p, miR-101-3p, and miR-145-5p of T2DM patients with MAC compared to those with NA. Statistically significant upregulation of miR-874-3p (p = 0.04) and miR-101-3p (p = 0.01) was seen in validation cohort. Significant negative correlations between the estimated glomerular filtration rate (eGFR) and miR-874-3p (p = 0.05), miR-101-3p (p = 0.03), and miR-145-5p (p = 0.05) as well as positive correlation between miR-874-3p and age (p = 0.03) were shown by Pearson's correlation coefficient analysis.
CONCLUSION: Upregulation of previously known miRNA, namely, miR-145-5p, and possibly novel ones, namely, miR-874-3p and miR-101-3p in the serum of T2DM patients, was found in this study. There was a significant correlation between the eGFR and these miRNAs. The findings of this study have provided encouraging evidence to further investigate the putative roles of these differentially expressed miRNAs in DKD.
Fulltext Exploring the Interplay of Factors in Chronic Kidney Disease: Insights from The Malaysian Cohort Study

INTRODUCTION: There is an increasing prevalence of chronic kidney disease (CKD) in Malaysia; hence, identifying factors associated with the early stage of CKD is crucial for preventive measures. This study investigated the association between various factors and their interaction in a multi-ethnic Malaysian cohort.
METHODS: A nested case-control analysis was conducted on 3,160 eligible participants with renal profile data from The Malaysian Cohort project. CKD status was determined by estimated glomerular filtration rate using the Chronic Kidney Disease Epidemiology Collaboration equation. Multiple logistic regression analysis using the likelihood ratio method was used to identify the factors and their interaction with CKD.
RESULTS: This study suggested five factors associated with CKD: gender, ethnicity, physical activity, atherogenic plasma index (AIP), and systolic blood pressure. There was an interaction between AIP and gender, with increased odds of CKD among men with high AIP.
CONCLUSIONS: As CKD is mainly asymptomatic until it is in the later stages, these five factors serve as valuable tools for predicting CKD and enhancing the identification of at-risk individuals, particularly among men with elevated AIP. Future studies should focus on using these factors, especially in preventing new CKD cases and their progression.
