March CAIR visit in Boston

Back home again after a "routine check-up" in Boston.  We are looking forward to spacing the trips further apart, but not sure when that will happen.  We had been going there every two months for visits, but last year went there nine times.  It is only March and we've been there twice this year already, with plans to return next month as well for another check-up. 

Peter has been doing well with a diet of real food during the day and unflavored formula overnight.  He has not gained enough weight or muscle mass to come off a night of TPN yet though.  He is down to 400 ml seven nights a week, which is down from the 750 ml that he had been put on after our last trip to Boston. 

While we were in Boston, we had some spare time before his appointment so we went to Trader Joe's and found a few fun things for Peter that were low in sodium.  (Thanks for your suggestion to look there, Colleen!)  They make a very flavorful tortilla chip that Peter fell in love with, called Veggie and Flaxseed Tortilla Chips.  He has eaten half a 12 ounce bag in two days!  He really craves flavor and there are three distinctly different chip flavors in the bag.  They have a long list of low-sodium products that they carry, which will be fun to explore.  Unfortunately, many of Trader Joe's products state that they may contain peanuts or be processed in a facility that uses nuts/peanuts, so we need to avoid them until we talk with an allergist about whether Peter can have nuts/peanuts, since he has a brother with peanut allergy.  But the chips were a great find.  We picked up some Falafel Chips to try as well, no peanut/tree nut warnings there either.  The plan between this visit and the next is to keep advancing nighttime feeds and try to get some more fat in during the day.  Dr. Kamin told us about whole milk Greek yogurt.  We have been using Chobani, which has lots of protein and Peter loves, but the highest fat yogurt they make is 2%, and usually we can only find 0%.  He only eats the plain flavor because, like the formula, when sugar is added the osmolality goes up and so can the ostomy output.  Even without an ostomy, people with short bowel syndrome often need to watch their sugars to keep stooling down.  We found some whole milk Greek yogurt yesterday, with fat content of 15%!  It looks like sour cream and is very rich.  Peter felt full faster, but we'll keep working with it to see if that might add some more calories.  He doesn't like to eat butter, but we are going to try to sneak that into his Gerber purees.  He always adds spices to them anyway, so it should be easy to get the butter in without his detection.  If we get a "clear" for trying peanut butter, that might give some healthy fat too.  He does drink whole-milk Lactaid. (Yes, he eats yogurt, but the team in Boston had awhile ago recommended Lactaid instead of milk, so we've still got him on that so we don't have to re-examine whether it is milk causing a problem with motility.)    He does not like avocados and gets tired of eggs after just a bite or two, but they would be good options for quality fat too.  Well, enough about food.

Of interest, images of Peter's liver circulation over the last several months seem to show that his portal vein clot is no longer there and that there is some blood flow through the portal vein.  Dr. Kamin indicated that this would be expected after time, but that if we looked right up on the portal vein, it would still appear different from a normal portal vein, perhaps scarred and with some reduced flow.  I did not realize that the vein would reopen, just thought collateral veins would develop in the belly to overcome the loss of portal vein flow.  Peter still has medusa-like veins on his belly, prominent and tortuous, but the hope has always been that with time and growth he would outgrow some of the portal hypertension.  There is likely a liver componenent to the portal hypertension as well, so that makes understanding the cause and detemining a solution difficult.  There has been discussion many times as to whether a shunt would help reduce the portal hypertension, redirecting the blood flow so that there is just less pressure.  The overriding thoughts of all doctors involved is that a shunt would not be good in Peter's case, as it could end up reducing necessary blood flow to the liver.  To hear that the portal vein does appear to have flow makes me even more optimistic that the portal pressure will continue to resolve over time, as we have all hoped.
