came across something interesting on my rotations today - how do you explain the following readings in a patient:

52 y/o M w/ a PMH of hypertriglyceridemia (previously 1000 down to 450 now with drugs - no PMH of familiar hyper-TG-emia, though), acute renal insufficiency, hypothyroidism, hypertension, (NO DM) and has always had FBG of 90s (last one was in June 08) suddenly test for a FBG of 185 (patient claims he was fasting for 12 hours just like he's always done for all the previous lab work-ups)??? I mean, I can see if the patient's BG was previously always bordering in the 120s then I might buy this FBG but 90s to 185 in 3 months????? Anyone else find this scenario fishy?? MD signed the report off as pt having T2DM...hmm??? I just think it's very unlikely to become clearly non-diabetic to full-blown diabetes (full-blown since usually 2 readings of greater than 126 or I believe it is 1 reading greater than 180?? I could be wrong)

Is there a med list? (I don't think this this seeking medical advice )

Repeat the test.....

And I was anticipating a brilliant clinical answer from you as I opened the thread only to read..."Repeat the test..." What a let down!

renal insufficiency can cause insulin resistance, increased hepatic glucose output and abnormal glucose metabolism in non DM patient. But we need more HX.

For giggles, what's the HbA1c?

For giggles, what's the HbA1c?

Took my question....

We had a patient on rounds today with A1c= 11.2 --which was down from last time when it was 13.5

I would go with the second test...

Without more information and more detailed history, I always look for the simplest and most logical solution. I guess it comes from years of diagnosing sick computers (my second life). By the way, it was a brilliant clinical answer based on the information provided.

what about an OGTT?

 

[Megas]

Maybe not so fishy? Hx of hypothyroid common in diabetics (have seen citations of 10-30%), maybe 1 autoimmune dis. (hypothy.) manifested before second autoimmune dis. (DM).
Any recent intro of SGAs, glucocorticoids in med hx?

 

[Megas]

Nobody posted after me. Am I a thread killer? OMG, I'm a thread killer (and a double-poster)!

 

[gaba101]

No OGTT done or HbA1C done; I just recommended that they repeat the FBG

 

[patmcd]

A repeat FPG is certainly a good idea. T1DM can occur at any age, so that is a possible cause of the rapid onset albeit not very likely.
