Dr. Hoehn-Saric studies various aspects of organ transplantation, specifically looking at how to enhance the health and success of kidney and pancreas transplants. He investigates conditions such as chronic allograft nephropathy, which is when kidney transplant patients experience a decline in kidney function. His work explores new treatments that adapt immunosuppressive therapies, ensuring better outcomes for patients. Additionally, he examines safety measures for pancreas transplants in diabetic patients with heart disease, aiming to maximize the number of patients who can safely receive transplants.
Key findings
In a study on chronic allograft nephropathy, 21 out of 28 kidney transplant patients showed improved kidney function after adjusting their immunosuppressive medication.
Among 316 patients undergoing pancreas transplants, heart disease increased serious complications from 2% in patients without heart issues to 11% in those with heart disease, indicating the importance of careful evaluations.
In his analysis of intertubular capillary changes in kidney transplants, Dr. Hoehn-Saric identified that severe changes indicate transplant damage, improving diagnostic accuracy for chronic rejection.
After implementing a family education program for kidney transplant candidates, the number of available living donors increased from 33.4% to 39.4%, particularly benefiting black and elderly patients.
In examining whole pancreas transplants, researchers found no evidence of recurrent type 1 diabetes, supporting patients’ options for managing their diabetes with this method.
Frequently asked questions
Does Dr. Hoehn-Saric study kidney transplants?
Yes, he focuses extensively on improving outcomes for kidney transplant patients, including new treatment methods for those with declining kidney function.
What are the benefits of pancreas transplants according to Dr. Hoehn-Saric's research?
His research suggests that pancreas transplants can be safe for patients with diabetes and heart disease, potentially leading to improved glycemic control without the risk of recurring diabetes.
Is there any research on living donors in kidney transplants?
Yes, Dr. Hoehn-Saric's studies show that educational programs can significantly increase living donor volunteer rates among kidney transplant candidates.
How does Dr. Hoehn-Saric contribute to patient safety in transplants?
He conducts research to ensure that comprehensive evaluations are in place, thereby allowing more patients with underlying conditions to safely receive transplants.

Plain English This study looked at how a structured education program for families of kidney transplant candidates influenced the number of living donors willing to help. Before the program, 33.4% of kidney transplant candidates had at least one potential living donor, but this number rose to 39.4% afterwards, particularly among black and elderly patients who traditionally had lower rates of donor volunteers. Living donors provided better transplant outcomes as well, with survival rates of 96.9% at one year and 93.2% at three years, compared to lower rates for cadaver donors.
Who this helps: This helps kidney transplant candidates, especially black and elderly patients, by increasing their chances of receiving successful living donor transplants.
Specificity of intertubular capillary changes: comparative ultrastructural studies in renal allografts and native kidneys.

Ultrastructural pathology
Drachenberg CB, Steinberger E, Hoehn-Saric E, Heffes A, Klassen DK +2 more
Plain English This study looked at how changes in small blood vessels in the kidneys can help diagnose chronic rejection of kidney transplants. Researchers analyzed 135 samples and found that while serious changes in these blood vessels often indicate a specific type of kidney transplant damage called transplant glomerulopathy (TG), similar, but less severe changes can also occur in native kidneys with other diseases, like lupus and hypertension. This matters because it helps doctors understand when TG is likely happening, especially when severe changes are present, improving kidney transplant care and monitoring.
Who this helps: This helps kidney transplant patients and their doctors.
Safe pancreas transplantation in patients with coronary artery disease.

Plain English This study focused on the safety of pancreas transplants in diabetic patients with heart disease. Researchers looked at 316 patients, finding that while 54% had significant heart artery blockages, only a few were excluded from surgery due to these concerns. Importantly, those without heart disease had much lower rates of serious heart problems after transplant (2% at one year versus 11% for those with heart disease), showing that careful heart evaluations allow more patients to safely receive a pancreas transplant.
Who this helps: This benefits diabetic patients needing transplants, particularly those with heart disease.
A novel approach to the treatment of chronic allograft nephropathy.

Transplantation
Weir MR, Anderson L, Fink JC, Gabregiorgish K, Schweitzer EJ +7 more
Plain English This study looked at a new treatment method for kidney transplant patients who were experiencing worsening kidney function. Researchers changed the immunosuppressive medication for 28 patients, reducing their cyclosporine dose by half and adding a drug called mycophenolate mofetil. As a result, 21 out of 28 patients showed improvement in kidney function, and the rate of kidney function decline significantly decreased, indicating that this approach can help stop or slow down kidney deterioration.
Who this helps: This helps kidney transplant patients experiencing loss of kidney function.

Plain English This study looked at kidney transplant patients whose biopsies showed "borderline changes," a category that usually doesn't require treatment. Out of 81 cases with these changes, about 78% of the patients with elevated creatinine levels received treatment for acute rejection, and most experienced some improvement in kidney function after treatment. This finding is important because it indicates that many patients who appear borderline may actually need treatment to protect their kidney transplants.
Who this helps: This helps kidney transplant patients who may benefit from timely treatment.
Histologic findings in islets of whole pancreas allografts: lack of evidence for recurrent cell-mediated diabetes mellitus.

Transplantation
Drachenberg CB, Papadimitriou JC, Weir MR, Klassen DK, Hoehn-Saric E +1 more
Plain English Researchers studied the condition of pancreatic islets in 55 patients who received whole pancreas transplants to see if they showed signs of a recurring immune response that can lead to type 1 diabetes. They found no evidence of specific inflammation in the islets that would indicate an attack on insulin-producing cells; instead, any inflammation present was linked to rejection of the transplant. This matters because it supports the idea that whole pancreas transplants are not at risk for recurrence of type 1 diabetes, which could encourage more patients to consider this option for managing their diabetes.
Who this helps: Patients with type 1 diabetes considering pancreas transplants.
