Summary: The aim of this study was to determine whether early measurements of serum aldosterone levels or plasmatic renin activity (PRA) could predict the need for surgical intervention in infants with obstructive congenital anomalies of kidney and urinary tract (CAKUT). A total of 20 infants aged 1-3 months with suspected obstructive CAKUT were prospectively enrolled and followed up for 2 years. The results showed that infants who required surgery had significantly higher levels of aldosterone at 1-3 months compared to those who did not require surgery (p = 0.006). The ROC curve analysis identified a cut-off of 100 ng/dL for aldosterone, which predicted the need for surgery with 100% sensitivity and 64.3% specificity. However, PRA measured at 1-3 months was not a predictor of surgery. In conclusion, early measurements of serum aldosterone levels can serve as a predictor for surgical intervention in infants with obstructive CAKUT.

Summary: Congenital anomalies of the kidney and urinary tract (CAKUT) is a common birth defect caused by complex genetic and environmental factors. Recent studies have suggested the involvement of long non-coding RNAs in the development of the kidney and urinary tract system. Research using PB transposon-based mutagenesis found that abnormal expression of Rik may lead to a reduction in UB branches by downregulating Bmp4, contributing to the development of CAKUT.

Summary: This review evaluates the efficacy of RAASi in treating proteinuria and CKD in children with CAKUT. While RAASi has shown effectiveness in reducing proteinuria and slowing CKD progression in many renal conditions, its efficacy in CAKUT patients is still uncertain. Therefore, a trial period of 6-12 months with gradual increase of RAASi dosage should be considered for CAKUT children with isolated proteinuria or proteinuria and CKD, and discontinuation of RAASi should be considered if no improvement in proteinuria is seen.

Summary: Ureteropelvic junction obstruction (UPJO) is a common cause of prenatal diagnosed hydronephrosis, with recent studies focusing on the use of ultrasound classification systems and MRI to stratify the risk in infants. Urinary biomarkers have also shown potential as a noninvasive alternative in identifying infants with clinically significant UPJO. Further research is needed to establish clear guidelines for evaluation and treatment to improve long-term outcomes for these patients.

Summary: The study showed that aliskiren significantly improved renal function, reduced necrosis and inflammatory cell infiltration in the cortex and medulla during acute and chronic partial ureteral obstruction in rat solitary kidney. Aliskiren also upregulated BCL-2 and downregulated IL-6, TGF-beta 1, collagen I, and fibronectin gene expression, while increasing GSH and SOD activity and reducing MDA and NO activity, leading to a more renoprotective effect when administered for four weeks compared to two weeks.

Summary: Redox signaling alterations contribute to CKD-associated cachexia. This review summarizes studies on the redox pathophysiology in CKD-associated cachexia and muscle wasting, and discusses potential therapeutic approaches using antioxidant and anti-inflammatory molecules to restore redox homeostasis. Antioxidant molecules have been studied in experimental models and patients with CKD, and oxidative stress is increased in CKD due to factors such as uremic toxins, inflammation, and metabolic and hormone alterations. Rehabilitation and anti-inflammatory molecules have shown beneficial effects for CKD-associated cachexia, and experimental studies have shown the importance of oxidative stress through the use of antioxidant therapies. Further studies are needed for potential therapies involving antioxidant therapy.

Summary: Diabetic cardiomyopathy is characterized by myocardial dysfunction in type 2 diabetes patients without traditional cardiovascular risk factors or overt clinical atherosclerosis and valvular disease. The activation of the renin-angiotensin system (RAS), oxidative stress, lipotoxicity, maladaptive immune responses, imbalanced mitochondrial dynamics, impaired myocyte autophagy, increased myocyte apoptosis, and fibrosis all contribute to the development of diabetic cardiomyopathy. Research has shown that the RAS plays a crucial role in this condition, with over-activation of the classical RAS axis leading to increased oxidative stress, fibrosis, and cardiac remodeling, while angiotensin-(1-7) has a protective effect. ACE inhibitors and angiotensin receptor blockers have been shown to improve heart functioning and reduce the occurrence of diabetic cardiomyopathy.
