Hi Red,
Don't be too concerned about the change in ferritin levels as ferritin levels can change because of other reasons, such as having a cold or infection, and the tests are not always totally accurate. See how it looks at your next test before you alter your chelation routine.
Some patients do get elevated creatinine levels while using exjade and this can be a sign of kidney disease. Patients with a prior history of kidney problems should discuss this with their physician before using exjade. All patients who do use exjade should have their creatinine levels checked at least once a month. If you haven't had high creatinine levels in the past and no kidney disease then you are a good candidate for exjade. I know many patients who are using exjade and also doing quite well in lowering their ferritin. It does seem that it takes awhile for ferritin to drop while using exjade, but after talking to dozens of patients who use it, what I have observed is that this happens because it takes some time to reach the maximum dose, as slowly raising the dosage is proving to be the best way to minimize the short term side effects, which include the rash and stomach discomfort. We also know several patients, including Danielle who are taking both exjade and desferal and having no problems with the combination, so if you're concerned about your ferritin rising when you start exjade, it is possible to continue with desferal too.
One thing I want to point out is that it is the consensus of top thal doctors that using more than one different chelator during your life is a better long term plan, as it reduces the long term side effects of the chelators. Desferal is known to cause hearing and vision problems in some patients over long use. L1 has very serious side effects in a small percentage of user (although, if more research is done into this, it may be found that the drop in white cells associated with L1 use, may actually be due to the white cell count dropping for other reasons. One member here was taken off L1 for some months when it was in fact the result of hepatitis C, which the patient was not aware of but the doctors were. I have noted that several patients I know have been taken off L1 when there was some other reason why the white cell count may have dropped. In most cases, L1 can be started again once the white cell count has risen). L1 is an excellent chelator that has been shown to extend the lives of thal patients better than any other chelator, largely due to its superior ability to remove iron from the heart. Unfortunately, it is not available in the US, other than in hardship status cases for patients who cannot tolerate other chelators.
It is absolutely up to you which chelator you choose and you brought up a point about attachment to the pump which is very valid. I have talked to many patients who have experienced some separation anxiety from their pumps once they started an oral chelator. It is very understandable, as patients view the pump as a protector and it isn't easy to abandon it. (By the way, anyone who has permanently abandoned a working pump, please let me know. Their are always patients asking for them and the cost is extreme for many patients. I can arrange for postage for anyone who wants to mail a pump). It may be time for you to consider an oral chelator, and as I said, you can continue desferal with either oral chelator, so that will give you a chance to see how well you tolerate exjade before committing to it. Start at a low dose and see how it goes.
