Thick skin and thicker arteries: case report on a rare cause of hypertension.
Pediatr Nephrol
January 2025
Department of Paediatric Nephrology, Christian Medical College, Vellore, India.
Renovascular hypertension is the second leading cause of hypertension. Twenty-seven genes have been attributed to monogenic renovascular hypertension at present. We present a 15-year-old boy with facial dysmorphism, thick skin and renovascular hypertension with a novel gain-of-function variant in SMAD4 gene suggesting Myhre syndrome.

Background: Multisystem inflammatory syndrome in neonates (MIS-N) is a rare condition thought to be associated with prenatal exposure to maternal severe acute respiratory syndrome coronavirus 2 infection. This immune-mediated hyperinflammation has been described in neonates with multiorgan dysfunction, including cardiopulmonary, encephalopathy, coagulopathy, and vascular complications. However, renovascular complications in MIS-N are rare.

BACKGROUND Arterial hypertension in pediatric patients often presents complex diagnostic and therapeutic challenges. The diagnosis of hypertension in children is based on different guidelines than in adults, with arterial hypertension in children defined as systolic and/or diastolic blood pressure values at or above the 95th percentile for age, sex, and height. Unlike adult populations, it is predominantly secondary in etiology, with conditions such as renovascular hypertension as common causes.

Poor blood pressure control in treated patients with hypertension is an important topic in the field of hypertension, and an unmet need for new therapeutic drugs remains. Soluble guanylate cyclase (sGC), a key signal transduction enzyme responsible for vasodilation, has attracted increasing interest as a therapeutic target in various cardiovascular diseases. Two different sGC agonists, sGC stimulators and activators, can increase its enzymatic activity in reduced and oxidized/apo forms, respectively.

Proteinuria, especially albuminuria, serves as an independent risk factor for progression in cardiovascular and renal diseases. Clinical and experimental studies have demonstrated that renal nerves contribute to renal dysfunction in arterial hypertension (AH). This study hypothesizes that renal nerves mediate the mechanisms of protein endocytosis by proximal tubule epithelial cells (PTEC) and glomerular function; with dysregulation of the renal nerves contributing to proteinuria in Wistar rats with renovascular hypertension (2-kidney, 1-clip model, 2K-1C).
