View Full Version : Difference between LADA and 1.5?

You guys are going to love this one.
I just got back from seeing my endo and I wanted to talk about my results. He dx'd me as a LADA but I tested negative for all antibodies with a 1.56 c-peptide. I'm black, 56 and until a few months ago, the picture of health.
What I wanted to talk about was the chance that I had "Atypical KPD". These are people who suddenly present with very high bg, are treated with insulin but then gradually become insulin independent and are then treated as t2's.
He noted that since the treatment for me as a LADA was the same for the Atypical KPD that the out come would tell what I was.
We are use to using the term LADA and 1.5 interchangeably but these Atypicals can and do go back and forth across beween being insulin dependent and insulin independent.

Hey, I'm not making this up!
http://www.ncbi.nlm.nih.gov/pubmed/15579799?log$=activity
Atypical ketosis-prone diabetes (http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=2592328)

From what I'm reading and from what the endo told me, most of these people were initially given a t2 dx and wound up in emergency with very high bg. After the bg was stabilized for a time, they went back to making there own insulin. Some. of course relapsed, some didn't. Some relapsed and still went back to being insulin independant.
The theory, from what I understand, is that high bg incapacitates the Beta cells. As this situation continues the bg worsens and a deadly spiral results. If normal bg is restored the Beta cells come back online and maintain relatively normal bg.
The really bad part for people with this is that most appear to be almost classic T2's but treating them initially as T2's could have very dire consequences.
I might be one of these types - I might not. Time will tell but I'm definitely keeping my 1.5 t-shirt.

Mike,

I understand that there are actually two types of type 1.5 diabetes: LADA (autoimmune based) and MODY (maturity onset diabetes of the young which is genetically based). Got any parental family history of diabetes?

Never heard of atypical KPD....but this just affirms my general mindset these days about diabetes....it's an unpredictable, constantly evolving/changing BEAST!

I think you might be talking about type 1b
Type 1B Or Idiopathic Diabetes (http://www.diabetestypes.org/type-1-diabetes/type-1-B-or-idiopathic-diabetes.htm)

Yep, this is a subgroup in t1b. I've come to think of Type 1b as the catch all place for diabetes that doesn't quite fit anywhere. Frankly, we are all so different in our diabetic responses, we all are idiomatic in some way. There seems be broad types but individually I'm finding that you really have to go by feel. The odd thing about this is that it should give people hope. Things might not be working but it doesn't mean it can't. There's probably as many solutions as people out there.

i am too tired to go the logical route..but as an aside..us type 1's lada..funky 1.5ers..we are diverse..and of course have our own funky challanges..but we are so cool...:)

Not often, but especially when I had a blood sugar crisis for several months back when I was 27 years old. My great-grandmother died of MODY3 at about 33-35 years of age of "brights disease" - essentially kidney failure and I woudn't doubt she had some ketosis going on (that was long before insulin was developed).

Most doctors do not look at MODY patients as severe enough to spill ketones - but that isn't my experience with my own MODY3. I think if you tie MODY3 together with beta-cell shut-down as blood sugar numbers stay high, then you can get there :eek:
