Hello, dear RLS friends! I would really appreciate your advice regarding my mother's ferritin levels. So she is currently on 0.375 mg (some days up to 0.5 mg) and 900 mg neurontin. I know DAs are not optimal, but at this point it would really be a problem to withdraw, especially that mom did start with neurontin and at a higher dose and it didn't help her. So she had one iron infusion a year ago, which was very effective. But recently she is starting to complain again, I am thinking it may be time for another one, please have a look at her blood levels and give some advice if you can:
levels before iron infusion: iron 13.55 µmol/g, latent iron binding capacity 44 µmol/g, total iron binding capacity 57.6 µmol/g, transferrin 2.76 g/L, transferrin saturation percentage 19.5 %, ferritin 96 µg
levels after iron infusion: iron 19.57 µmol/g, latent iron binding capacity 32 µmol/g, total iron binding capacity 51.6 µmol/g, transferrin 2.53 g/L, transferrin saturation percentage 30.8 %, ferritin 324 µg
levels now (a year after infusion): iron 12.8 µmol/g, latent iron binding capacity 37 µmol/g, total iron binding capacity 49.8 µmol/g, transferrin 2.53 g/L, transferrin saturation percentage 20.1 %, ferritin 142 µg
so my concern is whether it's acceptable to have an iron infusion at this quite normal ferritin level? I remember from some guidelines that this transferrin saturation percentage value must be 20% minimum.
and just another quick comment - mom's ALT level (liver ferment) is <6 - she never had it so low. Even though it is considered normal to have low values (high values are usually a concern), I read that low ALT levels may be caused by taking levodopa (she is not taking it, but DAs are sort of the same type, are they?) and anti-seizure drugs (which I believe neurontin is), plus it may be a sign of B6 vitamin deficiency, which also causes neuropathy. I will try to ask our neurologist about it, of course, but maybe somebody can add an input. Thanks again to every one here - you really help a lot!
