Introduction: The clinical management of the inherited bleeding disorder von Willebrand disease (VWD) focuses on normalizing circulating levels of von Willebrand factor (VWF) and factor VIII (FVIII) to prevent or control bleeding events. The heterogeneous nature of VWD, however, complicates effective disease management and development of universal treatment guidelines.
Areas Covered: The current treatment modalities of VWD and their limitations are described and why this prompts the development of new treatment approaches.

Diabetes insipidus (DI) is a rare endocrine disease involving antidiuretic hormone (ADH), encompassing both central and nephrogenic causes. Inability to respond to or produce ADH leads to inability of the kidneys to reabsorb water, resulting in hypotonic polyuria and, if lack of hydration, hypernatremia. DI cannot be cured and is an unfamiliar disease process to many clinicians.

Polyuria-polydipsia syndrome is composed of arginine vasopressin deficiency, arginine vasopressin resistance and primary polydipsia and are characterised by severe polyuria with hypotonic urine. The water deprivation test is commonly used to indirectly assess the vasopressin response to water deprivation. We report a woman in her 20s who demonstrated severe polyuria (11-12 L/day) on submitting a 24-hour urine sample for analysis.

Objective: The aim of this study was to explore the impact of arginine vasopressin (AVP) and angiotensin II (Ang II) on aquaporin 2 (AQP2) expression in M - 1 cells.
Methods: M - 1 cells were stimulated with desmopressin (dDAVP) and Ang II, followed by treatment with tolvaptan and losartan. The expression and protein levels of V2R, AT1R, AQP2, and p-S256AQP2 were measured via ELISA, western blotting, RT-qPCR, and immunofluorescence.
