The GranStone Trial

This study will investigate whether treatment with empagliflozin or losartan can reduce the risk of kidney stone formation in patients with paraffin disease, a condition caused by the injection of paraffin oil into muscle tissue for cosmetic muscle enlargement. Paraffin disease can lead to chronic inflammation, disturbances in calcium regulation, high blood calcium levels, kidney stones, and impaired kidney function. Previous studies from Herlev-Gentofte Hospital have shown that kidney stones occur in nearly half of affected patients, while approximately one-third develop reduced kidney function. Current treatment primarily consists of high-dose corticosteroids, which can reduce blood calcium levels but cause substantial adverse effects and may not adequately control the underlying disease process. Both empagliflozin and losartan are widely used medications with documented kidney-protective effects in other chronic kidney diseases. This randomized clinical trial will evaluate whether either treatment can prevent kidney stone formation and slow kidney-related complications in patients with paraffin disease. The purpose of this study is to determine whether treatment with empagliflozin or losartan can prevent kidney stone formation and improve kidney health in patients with paraffin disease.

Exploring Pathogenesis and Treatment of Hypercalcemia Caused by Intramuscular Injection of Paraffinoil

The aim of the study is to characterize paraffin oil induced granulomatous disease. We will investigate pathogenesis and natural history of paraffin disease. Subsequently, through further translational studies, we intend to identify novel treatments to be tested in future randomized clinical trials.
