CHAC1 Mediates Endoplasmic Reticulum Stress-Dependent Ferroptosis in Calcium Oxalate Kidney Stone Formation.
Adv Sci (Weinh)

Department of Urology, Renmin Hospital of Wuhan University, Wuhan, Hubei Province, 430060, P. R. China.
The initiation of calcium oxalate (CaOx) kidney stone formation is highly likely to stem from injury to the renal tubular epithelial cells (RTECs) induced by stimulation from an aberrant urinary environment. CHAC1 plays a critical role in stress response mechanisms by regulating glutathione metabolism. Endoplasmic reticulum (ER) stress and ferroptosis are demonstrated to be involved in stone formation.

Secondary hyperoxaluria is a metabolic disorder characterized by an increase in urinary oxalate excretion. The etiology may arise from an increase in the intake of oxalate or its precursors, decreased elimination at the digestive level, or heightened renal excretion. Recently, the role of the SLC26A6 transporter in the etiopathogenesis of this disease has been identified.

Advanced diagnostic techniques, such as infrared spectroscopy, provide precise stone analysis, enabling clinicians to tailor interventions based on specific stone types and associated metabolic abnormalities. Calcium oxalate monohydrate stones often require invasive approaches like percutaneous nephrolithotomy, while uric acid responds well to dissolution therapy.

Human lactate dehydrogenase A (LDHA) is a homotetrameric isozyme involved in the conversion of glyoxylate into oxalate in the cytosol of liver cells (hepatocytes) and partially responsible for the overproduction of oxalate in patients with the rare disease called primary hyperoxaluria (PH). Recently, LDHA inhibition has been validated as a safe therapeutic method to try to control the PH disease. Stiripentol (STP) is an approved drug used in the treatment of seizures associated with Dravet's syndrome (a severe form of epilepsy in infancy) which, in addition, has been drawing interest in recent years also for potentially treating PH, due to its LDHA inhibitory activity.

Obstetrics and Gynecology Department, Anhui Wannan Rehabilitation Hospital (The Fifth People's Hospital of Wuhu), 241000 Wuhu, Anhui, China.
Background: Urinary tract stones present significant health risks to pregnant women and their foetuses. However, the specific risk factors contributing to stone formation during pregnancy, particularly within the Chinese population, remain poorly understood. This retrospective survey aimed to identify demographic, clinical, and obstetric risk factors associated with urinary tract stones in pregnant women at a tertiary hospital in China.
