Pancreatitis from meds

Good day,
my granny (98 yo) suffers from pancreatitis episodes, she already went
to hospital 3 times and she always risked to die.

The pancreatitises are supposed to be from gallstones origin, however
these are inoperable because of her age etc. But she always had them,
while the pancreatitis episodes are relatively recent.

I noticed that two meds she has taken recently (and continues to take)
can cause sporadic pancreatitis episodes under cronic assumption:
enalapril maleate and furosemide. There is quite a lot of literature on
Pubmed on this, and for both meds. I understand that the gallstones
probably do a good part of the job, but inflamations IMHO are additive.

I noticed that among ace-inhibitors almost all are reported to have
caused some episodes of pancreatitis in literature except Fosinopril
(and Imidapril but that is not sold in my country).

What do you think about an enalapril to fosinopril replacement? I am not
a doctor.

If you think it's reasonable I would like to try to convince our doctor
to prescribe fosinopril (that won't be easy knowing our doctor so at
least I would like to know your opinion before).

The other one is furosemide. This I believe is even more difficult to
replace: almost all the other diuretics are reported to cause sporadic
pancreatitis episodes. The only class which does not have this problem I
think is anti-aldosterone. I know nothing of anti-aldosterones... can
they replace furosemide in an old woman with some hearth problems
(chronic atrial fibrillation, some degree of cardiac insufficiency).

Thanks in advance

Gallstone pancreatitis and chemical pancreatitis from those meds are two
completely different mechanisms and her doctor should have no difficulty in
determining which of the two mechanisms is the cause of her recurrent
pancreatitis. I think one can be fairly certain that the basis is gallstones
and that her meds are not contributing in any way.

Obviously, she needs to have her gallbladder removed. The risk of her dying
from that operation may very well be less than the risk of three or more
episodes of pancreatitis. Her doctors have likely put her at far greater
risk by NOT taking her gallbladder out.

This is interesting but contrary to what I knew... I think I read in a
paper something like "the pancreatitis from meds has no distinguishable
features..."

Anyway: can you provide more detailed info about how to discriminate
between the two?

At the hospital they just said that "when they find gallstones they
assume that the reason for the pancreatitis is gallstones and not a rare
side effect from a widely used medication"

This leads me to believe that they didn't do a real estimation of what
you say.

If you can tell me more about the differences...

This was my opinion also but they didn't want to operate her. The
anesthesist said she probably would not have passed the anesthesia. They
didn't speak about precise likelihoods.

Probably they thought that a death during an operation was not good for
their career, while the patient was alive and could be dismissed... :-(
It is sad but I kinda understand this.

Thanks for your help

"When you hear hoofbeats, think of horses, not zebras".

Common things present commonly...pancreatitis in the presence of stones in
the gallbladder is presumed to be gallstone pancreatitis. That it might be
due to medication is pretty much just wishful thinking.

In an episode of gallstone pancreatitis, one might expect to see elevated
direct bilirubin and alkaline phosphatase as well as radiographic evidence
of an enlarged common bile duct.

Thanks

Direct bilirubin normal at 0.18 mg/dl

Alkaline phosphatase elevated at 687 MU/ml however captopril is reported
to elevate alkaline phospatase sometimes
http://www.rxlist.com/cgi/generic/captop_ad.htm so it might be the same
for enalapril

ecography results: (translating to english at my best...)
"Choledochus at ilum measures 5mm and does not contain stones." I think
5mm is normal, right?
"Cholecistis is 'hydropic' (? maybe) and contains numerous stones of
14-22 mm of size and biliary sludge."

14mm are not likely to pass IMO.

The other reason that leads me to think "meds" is that at the previous
hospitalization they said that the gallbladder (or duct?) was so much
blocked with stones that stones would probably not pass anymore, hence
they said this was probably the last pancreatitis she would have had.
Which turned out to be not true...

TIA

Perhaps their whole proposed scenario makes more sense to someone who's
actually on-scene, and can review all the lab work/xrays, get a history, and
examine the patient. From here, it sounds like she's being mismanaged.
