Advances and challenges in kidney fibrosis therapeutics

  • Nature Reviews Nephrology
  • February 2025
  • Chronic kidney disease (CKD) is a significant global health issue impacting over 10% of the adult population. Current treatments such as dialysis and transplantation are expensive and do not provide a cure. Kidney fibrosis, characterized by an abnormal buildup of extracellular matrix in the kidney tissue, is a common consequence of CKD, regardless of its underlying cause, and is a leading factor in the decline of kidney function and eventual kidney failure. As a result, research efforts have been concentrated on identifying factors that contribute to kidney fibrosis in order to develop effective anti-fibrotic treatments. The transforming growth factor-β (TGFβ) family has been identified as playing a key role in fibrosis, leading to efforts to inhibit TGFβ signaling. While initial studies in animal models showed promise, the translation of these findings into clinical practice has fallen short of expectations. Although antihypertensive and antidiabetic medications have been shown to slow the progression of kidney disease and potentially fibrosis, the lack of technology for in vivo renal imaging hinders the ability to accurately assess their anti-fibrotic effects. The development of new drugs targeting pro-fibrotic signaling pathways, as well as those that promote cell repair and metabolic reprogramming, along with improved methods for identifying individuals with CKD and advancements in nanotechnology for kidney-specific drug delivery, offer new possibilities for addressing this significant public health challenge.

The Association of Outdoor Temperature with Severe Hyponatremia

  • Journal of The American Society of Nephrology
  • March 2025
  • Hyponatremia is a prevalent condition characterized by nonspecific symptoms and a complex etiology. The impact of outdoor temperature on hyponatremia remains understudied and varies depending on climate and location. This study sought to explore the relationship between outdoor temperature and the prevalence of severe hyponatremia.
  • The findings revealed a significant correlation between elevated temperatures and severe hyponatremia. Notably, the heightened prevalence of severe hyponatremia was most prominent among the elderly population. This underscores the importance of considering outdoor temperature as a potential contributing factor in the development of severe hyponatremia, particularly in vulnerable populations.

Sleep Disorders in CKD

  • American Journal of Kidney Diseases
  • February 2025
  • Sleep disorders are a common issue among patients with chronic kidney disease (CKD), yet they are frequently overlooked. The most prevalent sleep disturbances in individuals with CKD include insomnia, sleep apnea syndrome, restless leg syndrome, and periodic limb movement disorder. The presence of sleep disorders in CKD patients can exacerbate the already high morbidity and mortality rates in this population.
  • Detecting and managing sleep disorders in CKD patients can be challenging due to the overlapping symptoms with CKD itself, such as poor concentration, daytime sleepiness, and insomnia. Treating one symptom may negatively impact others, making the management of these disorders complex and requiring individualized approaches based on treatment response and potential adverse effects. However, addressing sleep disorders can lead to significant clinical benefits and improve the overall health-related quality of life for CKD patients.

A Pilot Trial of Nicotinamide Riboside and Coenzyme Q10 on Inflammation and Oxidative Stress in CKD

  • Clinical Journal of the American Society of Nephrology 
  • March 2025
  • Mitochondria-driven oxidative and redox stress, along with inflammation, are significant factors in the pathophysiology of Chronic Kidney Disease (CKD). Compounds that target mitochondrial metabolism have the potential to enhance mitochondrial function, reduce inflammation, and alleviate redox stress. However, there is currently limited evidence supporting their effectiveness in treating CKD.
  • A study conducted over a six-week period found that Nicotinamide Riboside (NR) and Coenzyme Q10 (CoQ10) led to improvements in markers of oxidative stress, inflammation, and cell bioenergetics in patients with moderate-to-severe CKD. This suggests that these compounds may hold promise as potential treatments for CKD.

Venous Thromboembolism Prevention in Nephrotic Syndrome: The Role of Aspirin, Vitamin K Antagonists, and Direct Oral Anticoagulants

  • Kidney International Reports
  • February 2025
  • Nephrotic syndrome (NS) poses a significant risk of venous thromboembolic events (VTEs), which can lead to increased morbidity and mortality. The current guidelines for VTE prophylaxis in NS patients are based on limited evidence, primarily from observational studies. This review delves into the complexities of hypercoagulability in NS, with a specific focus on aspirin as a potential prophylactic treatment.
  • We explore the pathophysiology underlying VTE in NS, shedding light on factors such as hypoalbuminemia, loss of anticoagulants, and heightened platelet reactivity. Additionally, we summarize the existing data on the efficacy of aspirin in reducing thromboembolic risk. While aspirin may offer benefits to certain patient populations, its overall effectiveness remains inconclusive. Some studies suggest that a combination of aspirin and anticoagulants may be more effective in reducing the risk of VTEs.

Clinical outcomes of patients undergoing hemodialysis with cool versus standard dialysate: A systematic review and meta-analysis.

  • American Journal of Nephrology
  • March 2025
  • Clinical practice guidelines recommend using lower dialysate temperatures (35.0°C–35.5°C) instead of the standard range (36.5°C–37.0°C) to reduce the risk of intradialytic hypotension. Despite these recommendations, numerous studies have been conducted since their publication. Therefore, the objective of this current study is to present an updated meta-analysis of clinical outcomes comparing cold dialysate to standard dialysate.
  • Utilizing cooled dialysate may offer a straightforward method to decrease the risk of interdialytic hypotension and improve mean arterial pressure, although it may come at the expense of patient comfort. The limitations associated with the quality of the studies included in this analysis highlight the necessity for high-quality, multicenter studies involving large and diverse study populations.

Sepsis-Associated Acute Kidney Disease Incidence, Trajectory, and Outcomes

  • Kidney Medicine
  • March 2025
  • The systematic evaluation of the prognosis of sepsis-associated acute kidney disease (SA-AKD) using real-world data is currently limited. This study aimed to utilize data algorithms on electronic health records to track the trajectory of SA-AKD from acute kidney injury (AKI) to chronic kidney disease (CKD).
  • It has been found that SA-AKD without recovery is linked to increased and long-term risks of kidney replacement therapy (KRT) initiation, mortality, and an elevated risk of de novo CKD-ND for patients who were initially free of CKD. Therefore, further studies are necessary to effectively manage the progression from AKI to AKD to CKD in real-world settings.

The acute effect of dark chocolate on blood pressure and renal hemodynamics as assessed with doppler ultrasound in healthy volunteers.

  • Journal of Renal Nutrition
  • March 2025
  • Dark chocolate, also known as DC, is a decadent treat that is abundant in cocoa, a compound known for its antioxidant and antihypertensive properties. Despite these well-known benefits, the impact of dark chocolate on renal hemodynamics remains largely unexplored. In order to address this gap in knowledge, a randomized, placebo-controlled study was conducted to investigate the effects of dark chocolate on blood pressure and renal perfusion. Doppler ultrasound was utilized to assess these parameters both at rest and during sympathetic stimulation, with white chocolate serving as the control.
  • The results of the study revealed that the consumption of dark chocolate led to an immediate decrease in renal resistive index (RRI), indicating vasodilation within the kidneys. In contrast, white chocolate had no discernible effect on renal hemodynamics. Interestingly, blood pressure only increased in individuals who were not regular consumers of dark chocolate, suggesting that habitual consumption may confer some degree of tolerance to its blood pressure-modifying effects.
