Hcy can be metabolized via remethylation to methionine or transsulfuration to cysteine which is dependent on several enzymes and cofactors. It is deleterious to blood vessel including glomeruli. Kidney is a major organ that metabolizes Hcy. More than 80% of patients with chronic renal disease develop hyperhomocysteinemia (hHcy). Accessible data of plasma Hcy in nephritic syndrome (NS) patients are controversial with increased, decreased and unchanged values reported. In renal patients, plasma Hcy concentration can be reduced by administration of folic acid. Absolute or relative deficiencies of folate, vitamin B6, or vitamin B12 may also play a role. Therefore, plasma Hcy, folic acid, vitamin B6, and vitamin B12 in children with acute glomerulonephritis (AGN) were accessed in this study. Hcy, folic acid vitamin B12, B6 and renal function such as blood urea nitrogen (BUN), creatinine (Cr) were analyzed 12 pediatric patients with AGN and 15 age and sex matched healthy children served as controls. The results revealed that a?significant increase in plasma Hcy in children with acute AGN when compared with controls. For simple regression analysis, Hcy was positively correlated with BUN, Cr, ferritin and uric acid but negatively correlated with serum glutathione. This research indicated hHcy suggests enhanced risks for inflammation and endothelial injury,?which lead to kidney disease. Folic acid has also been shown to improve endothelial function, suggesting an alternative explanation for the effect of folic acid on endothelial function. Careful considerations of not only dietary measures are necessary but also folate and vitamin B supplementation for reducing hHcy in AGN need to be investigated.展开更多

The data showed that the level of serum CMSC and ICPIC was markedly decreased in acute phase and returned to normal in the 7th week after onset of disease.Correlation analysis revealed that there were positive correlation between the level of serum CMSC and ICPIC and the serum concentration of CH50, C3, C4, but no linear correlation between the level of serum CMSC and ICPIC and the amount of CIC. These results suggest that the declined serum CMSC and ICPIC in AGN may be associ ated with the pathogenesis of AGN.展开更多

Meanwhile, there was a significant positive correlation between LPO and TXB2(r=0. 475,P<0.001 ), and a negative correlation between LPO and 6-KPGF1a(r=-0. 636,P<0. 001).All these indicate that FRs and PGs were all involved in the process of AGN and FRs destroyed renal tissue and physiology function themselves or by PGs generating.展开更多

Although infection is typically ongoing when patients present with SAGN, in the case of deep-seated infections, the presence of infection may not be apparent. The aim of this study is to highlight the importance of renal biopsy when the diagnosis is not obvious. We present a case of staphylococcus associated glomerulonephritis in a patient treated with beta-lactam antibiotics for staphylococcus bacteraemia. A renal biopsy helped differentiate between interstitial nephritis and staphylococcus associated glomerulonephritis.展开更多

This comprehensive review article provides an in-depth examination of the risk elements, etiology, diagnosis, management, and preventive approach of AKI. The causes that contribute to the development of AKI include prerenal, intrinsic renal, and postrenal. The diagnostic approach to AKI includes clinical, laboratory, and imaging studies to evaluate the root cause analysis and to find out the severity of kidney injury. Timely and accurate diagnosis is crucial for initiating appropriate management strategies. The treatment strategies may include fluid and electrolyte management, medication adjustments, nutritional support, and renal replacement therapy. The prospect of recovery diverges as it relies on the individual factors, reasons, and gravity of the condition. This review highlights the importance of raising awareness among healthcare professionals and the public about AKI, early recognition of risk factors, and prompt management. Further research is needed to explore novel therapeutic approaches and refine existing management guidelines for this critical condition.展开更多
