Risk Factors and Outcomes Analyses at 36 Months of a Prospective, Randomized, Multicenter, Trial of Daclizumab Induction in Simultaneous Kidney–Pancreas Transplant Recipients

Monitoring of nonsteroidal immunosuppressive drugs in patients with lung disease and lung transplant recipients: American College of Chest Physicians evidence-based clinical practice guidelines

OBJECTIVES

Immunosuppressive pharmacologic agents prescribed to patients with diffuse interstitial and inflammatory lung disease and lung transplant recipients are associated with potential risks for adverse reactions. Strategies for minimizing such risks include administering these drugs according to established, safe protocols; monitoring to detect manifestations of toxicity; and patient education. Hence, an evidence-based guideline for physicians can improve safety and optimize the likelihood of a successful outcome. To maximize the likelihood that these agents will be used safely, the American College of Chest Physicians established a committee to examine the clinical evidence for the administration and monitoring of immunosuppressive drugs (with the exception of corticosteroids) to identify associated toxicities associated with each drug and appropriate protocols for monitoring these agents.

METHODS

Committee members developed and refined a series of questions about toxicities of immunosuppressives and current approaches to administration and monitoring. A systematic review was carried out by the American College of Chest Physicians. Committee members were supplied with this information and created this evidence-based guideline.

CONCLUSIONS

It is hoped that these guidelines will improve patient safety when immunosuppressive drugs are given to lung transplant recipients and to patients with diffuse interstitial lung disease.

Delayed kidney allograft function after simultaneous pancreas-kidney transplantation

BACKGROUND

Simultaneous pancreas-kidney transplantation (SPKT) is one of the treatments for insulin-dependent chronic renal failure patients.

METHODS

One-year patient and kidney allograft survival rates of 150 patients undergoing SPKT were subjected to Cox regression and Kaplan-Meier analyses. Uni- and multivariate methods identified risk factors involved in allograft and patient survival.

RESULTS

One-year patient and kidney allograft survival rates were 82% and 80%, respectively. Delayed graft function (DGF) (P = .001; hazard ratio [HR]5.41) and acute kidney rejection episodes (P = .016; HR 3.36) were related to 1 year patient survival as well as intra-abdominal infection (IAI) rates. (IAI). One-year kidney allograft survival was related to DGF (P = .013; odds ratio [OR] 3.39), acute rejection (P = .001; OR 4.74), and IAI (P = .003, OR 6.29). DGF was related to a time on dialysis >27 months (P = .046; OR 2.59), cold kidney ischemia time >14 hours (P = .027; OR 2.94), donor age >25 years (P = .03; OR 2.82), and donor serum sodium concentration >155 mEq/L (P < .0001; OR 1.09). Female kidney to male recipient in 17% of the cases did not increase the risk of DGF. We observed an important correlation between donor serum sodium and creatinine (P < .0001), which suggested undertreatment of diabetes insipidus secondary to brain death.

CONCLUSIONS

DGF, acute rejection, and IAI were the main determinants of survival after SPKT. Improving the care of deceased donors may reduce DGF occurrence.

Acute Graft-versus-Host Disease in Pancreas Transplantation: A Comparison of Two Case Presentations and a Review of the Literature

As a complication of solid organ transplantation, acute graft-versus-host disease (GVHD) is most associated with small bowel and liver transplants. We present two cases of acute GVHD following pancreas transplantation. Case 1 was a 27-year-old female who underwent cadaveric pancreas transplant 9 months after a successful live donor kidney transplant. Case 2 was a 38-year-old male who received a simultaneous cadaveric pancreas and live donor kidney transplant. Both patients presented within 30 days of transplant with nonspecific symptoms. Rejection and infection were ruled out. Both subjects had progressive decline in mentation associated with pancytopenia and hyperbilirubinemia. Rash was not present until late in their hospital course. Skin biopsies demonstrated mixed chimerism with pancreas donor DNA diagnostic of GVHD. Acute GVHD is a rare, often fatal, complication of pancreas transplantation, and its presentation appears to differ from acute GVHD associated with stem cell transplantation.
