GLP-1 ile stimüle insülin salınımında santral nöral yol majör bir rol oynamaktadır

• GLP-1, vagal afferent duyusal nöronlarla etkileşebilir

• Gİ sistemde, hepatoportal bölge ve/veya karaciğer dokusu

• Beyin sapı ve/veya hipotalamusta refleksler oluşturma

• Bu, pankreas ve Gİ sisteme stimüle eden veya inhibitör uyarılar yollayarak vagal motor nöronlarını aktive eder

Acute Pancreatitis in Type 2 Diabetes

Treated With Exenatide or Sitagliptin A retrospective observational pharmacy claims analysis RAJESH GARG, MD 1

WILLIAM CHEN, PHD, MPH 2

MERRI PENDERGRASS, MD, PHD

2,3

OBJECTIVE— Cases of acute pancreatitis have been reported in association with exenatide,

sitagliptin, and type 2 diabetes without use of these medications. It remains unknown whether

exenatide or sitagliptin increase the risk of acute pancreatitis.

RESEARCH DESIGN AND METHODS— A retrospective cohort study of a large medical

and pharmacy claims database was performed. Data for 786,656 patients were analyzed. Cox

proportional hazard models were built to compare the risk of acute pancreatitis between diabetic

and nondiabetic subjects and between exenatide, sitagliptin, and control diabetes medication

use.

RESULTS— Incidence of acute pancreatitis in the nondiabetic control group, diabetic control

group, exenatide group, and sitagliptin group was 1.9, 5.6, 5.7, and 5.6 cases per 1,000 patient

years, respectively. The risk of acute pancreatitis was significantly higher in the combined

diabetic groups than in the nondiabetic control group (adjusted hazard ratio 2.1 [95% CI

1.7–2.5]). Risk of acute pancreatitis was similar in the exenatide versus diabetic control group

(0.9 [0.6 –1.5]) and sitagliptin versus diabetic control group (1.0 [0.7–1.3]).

CONCLUSIONS— Our study demonstrated increased incidence of acute pancreatitis in

diabetic versus nondiabetic patients but did not find an association between the use of exenatide

or sitagliptin and acute pancreatitis. The limitations of this observational claims-based analysis

cannot exclude the possibility of an increased risk.

Chronic GLP-1 Receptor Activation by Exendin-4 Induces Expansion of Pancreatic

Duct Glands in Rats and Accelerates Formation of Dysplastic Lesions and

Chronic Pancreatitis in the KrasG12D Mouse Model

Belinda Gier,Aleksey V. Matveyenko,David Kirakossian,David Dawson,Sarah M. Dry,

and Peter C. Butler Diabetes 61:1250–1262, 2012

The extent and frequency of PDGs(Pancreatic Duct Glands) surrounding the

main pancreatic duct are increased by exendin-4 treatment in rats.

Sections from the head of the pancreas from an untreated control rat

27/05/2013

F–H: In addition, the epithelium often showed pseudostratification

and pseudopapillary features, which are features characteristic for

PanIN-like ( pancreatic intraepitelial neoplasia) lesions.

27/05/2013

27/05/2013

PDG cell replication is increased by exendin-4 treatment in rats.

27/05/2013

Exendin-4 treatment increased chronic pancreatitis and the frequency of mPanIN

lesions in Pdx1-Kras mice. Pancreata from Pdx1-Kras mice treated for 12 weeks with

either vehicle (A) or exendin-4 (B) (203 objective). The pancreas from the exendin-

4–treated animal demonstrates only scant residual intact acini (white arrow) with

more extensive inflammation and fibrosis (stars) and more frequent mPanIN (black

arrows).

27/05/2013

Duct cell replication frequency is increased in the pancreas of exendin-4–

treated Pdx1-Kras mice. Immunohistochemical labeling of Ki-67–positive cells

(brown; counterstained with hematoxylin) in benign ducts in areas of intact acinar

tissue in control mice (A) and exendin-4–treated mice (B).

There were no cases of pancreatitis, macroscopically or microscopically, in 400 rats.

Neither pancreatitis nor preneoplastic proliferative lesions was found in monkeys

dosed for 87 weeks, with plasma liraglutide exposure 60-fold higher than that

observed in humans at the maximal clinical dose. In conclusion, liraglutide did not

induce pancreatitis in mice, rats, or monkeys when dosed for up to 2 years and

at exposure levels up to 60 times higher than in humans.

Summary of pancreatitis findings

• While more cases of acute pancreatitis were reported with liraglutide vs. comparators, the estimated reporting rate ratio elevation was not statistically significant

• Reporting rates were low and within the predicted range for a population of patients with type 2 diabetes

• Considering patient histories, most reported cases of acute pancreatitis were unlikely to be linked to liraglutide treatment

• Overall, there are too few cases to be able to determine whether or not there is a cause-and-effect relationship between the development of acute pancreatitis and treatment with liraglutide

• Liraglutide has no adverse effects on the pancreas in animal studies

What is to come...

• Preclinical mechanistic safety studies investigating pancreatitis

• Two pharmacoepidemiological trials1

• using i3 Aperio and the Clinical Practice Research Datalink

• LEADER® will study pancreatitis safety in >9000 patients2

• information related to acute or chronic pancreatitis, as well as history of gallbladder disease, will be recorded at screening

• amylase and lipase will be measured at randomisation (visit 3) and again at visits 6, 7, 9, 11, 13 and 15

• additional measurements will be mandated in case of persistent, severe abdominal pain potentially suggestive of pancreatitis

• all suspected events of acute pancreatitis will be evaluated by an independent event adjudication committee

Imbalanced protease expression and activities may contribute to the development of

cancers including neuroblastoma. Neuroblastoma is a fatal childhood cancer of the

sympathetic nervous system that frequently overexpresses mitogenic peptides,

chemokines and their receptors. Dipeptidyl peptidase IV (DPPIV), a cell surface

serine protease, inactivates or degrades some of these bioactive peptides and

chemokines, thereby regulating cell proliferation and survival.

These data support a potential role for DPPIV in

inhibiting neuroblastoma growth and progression.

angiogenic structure) in vitro. HUVECs were co-cultured with control or DPPIV

expressing SK-N-AS cells for 18 h on matrigel basement. (a)Representative

DPPIV re-expression suppresses the tumorigenic potential of SK-N-AS cells in a

xenotransplantation mouse model. Two different sets of nude mice (BALB/C nu/nu,

n = 5 for each group, SK-N-AS+Vector or SK-N-AS+DPPIV) were injected

subcutaneously with 5X106 cells as a 50% suspension in matrigel. Tumors were

measured every 3 days. A. a.Effects of DPPIV on tumor growth. Results are presented

At present, the GLP-1 class of drugs is heavily promoted (and prescribed) as

having purported advantages that outweigh its risks. Singh and colleagues

provide a timely reminder that, despite large numbers of underpowered

studies claiming the contrary from marketing companies, little is yet

known about long-term adverse effects of the GLP-1 class of drugs on the

exocrine pancreas.

Unfortunate recent history documents unacceptable delays by regulatory

authorities to act on serious adverse effects detected in postmarketing

surveillance of drugs for T2DM, deemed 2 times a farce by Gale.11 We

hope history will not repeat itself with the GLP-1–based drugs, because in

this case, 3 times would not be a charm.
