Pancreas: head, body, and tail- bread loaf so paraffin and OCT are harvested in alternating sections:

1. Snap frozen vials with minced tissues and with or without RNAlater- 4 or more vials each from junctions of head and body and body and tail regions.

2. Paraffin blocks- 5-10 (OCT takes precedence over fixed when sample size is small)

3. OCT blocks- 5-10 all regions or as indicated by size

PLN:

1. OCT blocks – 3-5- as many as feasible depending on total numbers

2. Cells- place several dissected LNs in 15ml tubes containing sterile RPMI, hold at refrigeration until shipped or processed. 1-4 tubes depending on numbers

3. Frozen vials as for pancreas. Paraffin is optional.

Spleen and NonPLN: as for PLN. Paraffin is optional.

Duodenal mucosa: as for pancreas. Paraffin is optional.

nPOD Case Classification

`In the absence of islet autoantibodies or histopathology can we determine whether an individual has Type 1a’ diabetes after death?

George Eisenbarth 2011

Page 11: What’s New at nPOD? · 2013. 8. 5. · • DKA • HLA • FCP < 3.7ng/mL •

For nPOD to impact the underlying mechanisms leading to T1D

……………………………….and ultimately complications

will require sufficient and appropriate cases early in disease process

•  Antibody positive non-diabetic: multiple; younger •  Early (new-onset) •  Age matched controls: healthy; type 2 •  Accurate phenotypic characterization: ideally before

death

Page 12: What’s New at nPOD? · 2013. 8. 5. · • DKA • HLA • FCP < 3.7ng/mL •

Challenge •  Long duration of disease in many cases (median 12, range 1-44 years) •  Incomplete information Information gathered from the terminal medical charts and OPO questionnaires; Type 1a vs Type 1b vs Type 2

•  Exclude secondary causes eg steroids, medications, CFRD

•  Exclude immediate potential co-morbidities which might impact subsequent findings

•  Histology (UF) Type 1 diabetes (52)

40 - no insulin+ islets 12 - insulin+ (8 reduced, 4 many, 3 amyloid, 3 C-peptide) 8 - insulitis

Type 2 diabetes (16) 1 - no insulin+ islets 15 - insulin+ (7 reduced, 8 many - 5 have amyloid, 5 C-peptide) 0 - insulitis

Page 15: What’s New at nPOD? · 2013. 8. 5. · • DKA • HLA • FCP < 3.7ng/mL •

Conclusion

Thorough phenotypic characterization suggests most cases classified correctly despite low frequency of islet autoAb in longstanding diabetes

Histology needed in islet autoAb negative

cases to distinguish type 1a vs type 1b

Other Comments (Total Respondents) •  How do you share data (9) : Discussions with colleagues/ publications/

meetings/ conferences/ nPOD webinars and meetings/ local lab

•  Data sharing concerns (14): How will shared data be handled for similar projects/ Publishing novel findings, data repositories – when and how/ none – trust nPOD with unpublished information/ will this prevent collaboration and lessen rigor of study, promoting other labs to publish for the sake of being first/ sharing of stained sections submitted for publication but not yet accepted

•  Desired security of nPOD online database (13): Restricted to nPOD data sharing investigators only/ restricted to registered members only/ high/ standard login/ protect data from being altered or corrupted/ disclaimer about unpublished data/ know who is accessing data

•  Other Comments/Suggestions (8): Update online information for older cases where tissue pieces are no longer available/ advice on restricted samples that can no longer be accessed/ advance warning when a user reaches his or her limit to donor samples

The Future - Pushing the Boundaries and Advocating for Complications Research

in Type 1 Diabetes •  Approach existing networks (complications, clinical trials) to

obtain more cases with well defined natural histories & medical records

•  Obtain partial medical records of nPOD donors (in general population)

•  Create data base for storage of: •  PartialmMedical history •  Research data

•  Serve as a model for other registries/biorepositories in T1D…encouraging openness

•  Include analysis of those with T2D

Why is nPOD-E Important? •  Main goals:

1.  Expand organ collection (and distribution) by creating a network for organ recovery at qualified sites in European countries

2.  Obtain immediate access to highly valuable stored samples

3.  Provide the resources of nPOD tissues to European investigators, as well as those in the U.S.

nPOD-E Overview

•  Collaboration sites in Sweden & Finland – Working together to increase nPOD

investigator access to tissue samples

•  Individual sites established in Italy & Spain – Will screen, recover, store, and distribute – nPOD structural model utilized

Page 61: What’s New at nPOD? · 2013. 8. 5. · • DKA • HLA • FCP < 3.7ng/mL •

Collaboration Site Progress •  Sweden:

–  Collaborating with Dr. Gun Frisk, at Uppsala University, to obtain retrospective and prospective tissue samples, specifically islets from AAb+ donors.

–  Have received 365 slides from a pre-existing donor collection.

•  Finland: –  nPOD-E is collaborating with Dr. Hyöty, at the University of

Tampere, and the PEVNET/Europod project by developing coordinated activities (specimen distribution, data, data management, other).

Established 2 New Sites in Europe •  nPOD-E Italy:

–  Established new nPOD-E site in Siena, Italy with Dr. Francesco Dotta.

–  Similar to nPOD, this project will screen and recover Aab+ and T1D donors from multiple sites and use all of nPOD’s SOP.

•  nPOD-E Spain: –  Established new nPOD-E site in Barcelona, Spain with Dr. Eduard

Montanya. –  This project will recover from AAb+ and T1D donors. And use nPOD

SOP for its screening, recovery, case processing and distribution methods.

•  Screening and recovery efforts for both to begin in February 2012.

nPOD-T nPOD-T aims at establishing feasibility of procuring human pancreatic tissue from transplanted T1D patients, when possible both transplanted and native pancreas

This should allow for scientific discovery in relation to:

•  recurrent disease, which mimics spontaneous disease development, correlating biopsy data with clinical data

•  immunosuppression and potential regeneration

•  rejection and other chronic changes

Page 76: What’s New at nPOD? · 2013. 8. 5. · • DKA • HLA • FCP < 3.7ng/mL •

nPOD-T nPOD-T aims at collecting tissues in three different settings:

1. Organs/tissues from transplant recipients (post-mortem)

2. Biopsies of native and transplanted pancreas

•  at the time of transplantation

•  for recurrent disease and/or rejection, or hernia/other reasons

3. Archived biopsies
