First off, some current stats for our 14 months old. He is now weighing 18.7lbs (Yippee!) which is still small for his age, but he has gained over two pounds in three months, which is big for him. He is climbing on EVERYTHING! His favorite past times are getting into the dog water, throwing things in the trash and playing in the toilet. If we find ourselves missing a utensil or remote, we know he has thrown it into the trash. We are pretty certain that we have already lost a whisk to this past time. He not only sucks his thumb but plays with his hair behind his ears. (As seen in the photo below.) We are seeing a very stubborn side to him recently. If he doesn't like something, he will let you know! And the best news of all, he is walking!!!
Now on to the kidney info. We got blood work last week. (While we were at the doctors, they noticed a start of an ear infection, which is his first.) The first thing the doctor looked at today was his ultrasound results. When he was a newborn, his kidneys were measuring 2.4 and 2.9 cm., normal size being 5 cm. His scan in July showed his kidneys had grown to 4.2 and 4.4, average being 6.3. When you look at his growth in comparison, this is a good number. The doctor charted the numbers and it appeared that Nate's kidneys were on the very, very low side of normal.....NORMAL!!! My heart lept thinking that maybe this was the start of "the end" with his kidney concerns. Well, then we moved on to the blood work.
His blood work was pretty consistent with the numbers we were seeing in the past. Creatinine remains at a .67, normal being .5. He has given a new blood test this time which measured his Vitamin D levels, turned out to be normal. The one number that continues to worry his doctor is his acid level. Nate is currently on medication to assist this level in regulating itself. Each appointment the doctor chooses to up his dosage, because it doesn't appear to be hitting where he needs to be. Today that number was again extremely low. So we are upping the dose again. The side effect associated with this low function is low weight gain, which we are obviously seeing in Nate.
Last but not least, Nate's urine was tested for the first time today. In the urine there is already evidence that Nate is losing protein. This number is what seemed to concern the doctor the most. The way he described it was Nate's little kidneys are compensating for their size. The little nephrons have grown in size to help with the demand for the filtering. There is a lot of pressure on these little cells to do a lot of work. Because of that pressure, they have a tendency to leak protein. He is going to have to start Nate on a medicine he wasn't planning on giving him until later in his life. This medicine will take some of the pressure off of his kidneys and not make them work so hard. So instead of maintaining a creatinine level of .6, the kidneys will only have to work to maintain a .7 or .8. In the end, this will help Nate elongate the life of his kidneys. Once scar tissue starts building up (because they are working so hard) it will be the beginning of the end for his little kidneys. So if we make them not work as hard, we might get a few more years out of them. His functionality of his kidneys is currently estimated at around 59%. This means he is right on the edge of being considered Stage III of kidney disease. (60% would mean he is in Stage II.)
We are still uncertain what this means for his future. The doctor is still hopeful that Nate will make it to his teenage years before needing a transplant, so we are not out of the woods, unfortunately. So we will "just keep swimming" as Dory the fish says. Nate has come so far in the last 5 months. All we can do is keep doing what we are doing. We are trusting God for where he takes us with this. Please continue to pray for our little guy. He is such a trooper!
