Re: 3 year old with possible kidney issues
Protein and blood in the urine along with a high creatinine is a sign of nephritis, an inflammation of the kidneys. This is a general term which describes the symptoms but doesn't tell you why it is there. Your little one should be checked thoroughly for strep related nephritis, which can occur following a strept infection, particularly one that is not treated, and autoimmune disorders such as lupus, that can cause nephritis. Lupus can occur in kids 3 years and up, so although unusual at this age, not unheard of. There are many other possibilities as well, but a nephrologist should be able to get to the bottom of it. I would question your child about a sore throat, and make sure a culture is done, so it can be treated if present. Any family history of autoimmune disease is important in history. An ultrasound of kidneys can be done to determine kidney size and position, etc. and to see if there are cysts or any other abnormalities. Proper diet is important especially if the creatinine is considerably elevated. A dietician consult might be helpful to learn what foods to encourage, what to avoid, like excess protein, and ways to ensure adequate calorie intake when appetite seems poor. Many children refuse to eat because their throat hurts when they swallow, and that connection is not always made. Fluid intake is an important aspect of care with kidney issues, depending on how severe it is. You mentioned seeing a ped. urologist, but I think a nephrologist (kidney specialist) is important given your child's symptoms. A urologist deals with lower urinary tract problems more than the kidneys themselves.
