This clinical trial is focused on studying the effects of a medication called prednisolone in treating a kidney condition known as acute interstitial nephritis. Acute interstitial nephritis is a condition where the spaces between the kidney tubules become swollen, which can affect kidney function. Prednisolone is a type of medication that helps reduce inflammation and is commonly used to treat various inflammatory conditions.

The purpose of this study is to investigate how effective prednisolone is in treating acute interstitial nephritis. Participants in the study will receive either prednisolone or a placebo. The study will monitor the kidney function of participants over a period of time to see how well the treatment works. The treatment will be administered in the form of tablets taken orally, and the study will last for a maximum of eight weeks.

Throughout the study, participants will have their kidney function checked at different intervals, including three months and twelve months after starting the treatment. The study will also look at other factors such as the stage of chronic kidney disease, the number of patients requiring dialysis, and the presence of any side effects like changes in blood sugar levels or infections. The goal is to gather information on the effectiveness and safety of prednisolone in managing acute interstitial nephritis.
