I've seen at least a thousand acth stims with serum acth over the years I've been doing this and never seen the combo of values you have. Your stim suggests secondary AI. I've never seen a secondary (going by a stim that doubled or more from a low value) with serum acth greater than 43. I've never seen a primary who doubled or more on the stim. I look for upper 40's to low 50's for a good acth. Your DHEA suggests primary. I recommend you read what wrote about interpreting the acth stim and acth serum tests.

Your pregnenolone suggests hypopituitarism (acth, LH and FSH regulate pregnenolone which breaks down into DHEA, cortisol and sex hormones, so low pregnenolone suggests ACTH, LH and FSH are low).

Very wierd set of tests you have. I'm thinking you should be retested with ITT test instead of ACTH stim though ITT is used to stim, CRH, ACTH, cortisol and growth hormone and I recommend these all be tested in the ITT.

I recommend you get aldosterone and renin tested (fast salt 24 hours) especially if you have salt wasting symptoms (hard to handle outside heat, excessive sweating, excessive urination). Low renin (labs usually give the range for non fasting salt which is around 3-6, non fasting is about 3-24) is what secondaries have 99% of the time. Primaries have high renin. Aldosterone, fasting salt is around 4-22, labs usually give non fasting salt range. Secondaries will have low potassium 99% of the time, though some are in the middle of the range and it could go either way then. Primaries have high potassium, though some are in the middle of the range.

I recommend you also get total and free testosterone, LH, FSH, Estradiol, SHBG, igf-1. In primary hypogonad men, most will be top of the LH and FSH range to just above, secondary hypogonad men, 99% will be low, but in range.

Since thyroid always goes hand in hand with primary and secondary AI, also recommend you get TSH, free T3, free T4, TPO and Tga thyroid antibodies tested. In men, primary hypothyroid will be above 2.2 and higher, secondary is 1.8 or lower. Between 1.8 and 2.2 not so clear which it is if frees are low and hypo symptoms.

Wouldn't hurt to get prolactin tested, but in most cases isn't important to men unless top or above range, then prolactinoma tumor should be investigated. Sometimes hypothyroidism can raise prolactin which usually comes down when thyroid is treated.

Hang in there.

I've read the ACTH "Inperpretation Guide" on other forums (STTM) before, and I too was leaning towards Secondary, but my ACTH vs Cortisol looks like my Pit knows it's too low and is "raising it's voice" (we don't yell/shout in our household :D) to try to get more Cortisol.

Do you have references (that are legal to post here) that state that low Pregnenolone is a marker for Hypopituitarism? I thought since Preg. was a precursor for DHEA, and since my ACTH is probably high all the time, that it is all used up making DHEA and the other Adrenal products, (but not Cortisol for some reason - maybe an enzyme deficiency that is blocking Cortisol synthesis?). Doesn't the high ACTH in response to chronic lower Cortisol make Hypopituitarism less likely? (FSH/LH are low, but we'll get to that later). Also, since Aldosterone isn't ACTH depentent, wouldn't Pregnenolone need to be indepentend of ACTH as well, (or am I out in left field)?

Hopefully in "Round 2" with my Endo, he'll do the Aldosterone/Renin tests, (along with the Estradiol since it was high on the Saliva stuff). I have the "Hard to handle outside heat" thing, but I live in the Southern States, so that doesn't say much. ;) I haven't noticed any "excessive sweating" or "excessive urination", but if it were congenital, (which I suspect it is), then I wouldn't have a good point of reference to compare "excessive" to. Potassium and Sodium look ok. I did have a slightly low Potassium of 2.9 once back in 1994, but that was a while ago.

Sex hormones are another puzzler. As you can see, my T's, SHBG, and my FSH/LH are low, but my IGF-1 and Albumin are high. He didn't check Estradiol (E2), but since it was pretty high on the Saliva testing, I suspect it's pretty high. I read in some Endo training materials that the Hypothalamus can't tell T from E2, so if E2 is high it will lower GnHR and thus drop LH/FSH, and lower T/DHT production. Since low T/DHT means E2 synthesis isn't as repressed, more E2 is produced, the Hypothalamus sees too much sex hormones, and the cycle continues. I don't have Gynecomastia, (male boobies), but I don't think that rules out "Male Estrogen Dominance". It may be something as simple as too much T is being Aromatased into E2, and could I just use something to slow down the conversion, but there isn't a lot of info on this topic that I've found. I've called my Endo and left several messages asking to come in and check E2 and Aromatase rate, but I haven't heard anything back yet.

Thyroid function looks normal, (as far as TSH vs FT4), since it looks like my Thyroid is "following orders" and making as much T4 as the Pit wants. I know the TSH is lowered, but I think that has to do with low Cortisol downregulating Thyroid function instead of Hypopituitarism. The real puzzler is what is causing my FT3 to be +50 percentile higher then my FT4. I thought it was low Cortisol which prevents binding of the T3 at the cell and thus causing an increase in circulating T3, (what I term "Effective Hypothyroidism" since it's there but I can't seem to use it). I also read on a few other boards that E2 and T3 both compete for the same receptors, so high E2 might also explain the extra floating T3, (but I don't have any references other then a few posts on a Body Building forum). I'm still a little unsure as to if the Hypothalamus looks at FT4 or FT3 to regulate the Thyroid, so the relative elevated FT3 could also be a factor in causing the lowered TSH.

Prolactin, WBC, and RBC look good, so I don't suspect a tumor.

Iron, Ferritin, HGB, and HCT are a bit low, but that has to do with giving myself temporary low-iron Anemia, as I stated previously.

(Is it just me, or is this starting to feel like an episode of "House"...) :(
