RESUMEN

While recent policies have focused on allocating organs to patients most in need and lessening geographic disparities, the only mechanism to increase the actual number of transplants is to maximize the potential organ supply. We conducted a retrospective cohort study using OPTN data on all "eligible deaths" from 1/1/08 to 11/1/13 to evaluate variability in donor service area (DSA)-level donor authorization rates, and to quantify the potential gains associated with increasing authorization rates. Despite adjustments for donor demographics (age, race/ethnicity, cause of death) and geographic factors (rural/urban status of donor hospital, statewide participation in deceased-donor registries) among 52 571 eligible deaths, there was significant variability (p < 0.001) in donor authorization rates across the 58 DSAs. Overall DSA-level adjusted authorization rates ranged from 63.5% to 89.5% (median: 72.7%). An additional 773-1623 eligible deaths could have been authorized, yielding 2679-5710 total organs, if the DSAs with authorization rates below the median and 75th percentile, respectively, implemented interventions to perform at the level of the corresponding reference DSA. Opportunities exist within the current organ acquisition framework to markedly improve DSA-level donor authorization rates. Such initiatives would mitigate waitlist mortality while increasing the number of transplants.

RESUMEN

Histoplasma capsulatum sporadically causes severe infections in solid organ transplant (SOT) patients in the Midwest, but it has been an unusual infection among those patients followed at the University of Nebraska Medical Center (UNMC), located at the western edge of the 'histo belt.' Nine SOT patients with histoplasmosis are described (6 renal or renal-pancreas and 3 liver recipients) who developed severe histoplasmosis over a recent 2.5-year period at UNMC. Symptoms started a median of 11 months (range, 1.2-90 months) after organ transplant and consisted primarily of fever, cough, shortness of breath, and malaise or fatigue present for approximately 30 days prior to medical evaluation. All patients had an abnormal chest radiograph and/or computed tomographic scan. Tacrolimus was the main immunosuppressant in all 9 patients, along with prednisone or mycophenolate. Dacluzimab or thymoglobulin had been given around the time of transplant in 6 of 9. None was treated for an episode of acute rejection within 2 months before onset of histoplasmosis, although 2 were on high-dose immunosuppression after recent transplants. Diagnosis was made by culture in 8 of the 9 patients, with positive serum and urine histoplasma antigen tests in all 9 cases. From 1997 to 2001, during a period of relative quiescence of the disease in the general population, the rate of clinical histoplasmosis among SOT patients at UNMC was estimated at 0.11%, whereas during 2002 through the first half of 2004, the rate rose 17-fold to 1.9%. Histoplasmosis can present as a prolonged febrile illness with subacute pulmonary symptoms in a cohort of SOT patients, despite the absence of a regional outbreak.

RESUMEN

BACKGROUND: Hepatitis C (HCV) universally recurs following orthotopic liver transplantation (OLT), representing an important cause for retransplantation. Although it is often treated with interferon and ribavirin, ribavirin is contraindicated in the presence of renal failure. In this setting of renal failure, pegylated-interferon monotherapy may be useful for recurrent HCV in liver transplant patients. METHODS: Between June 2001 and November 2002, patients with recurrent HCV were screened to determine if they were eligible for treatment. Renal failure was defined as serum creatinine greater than 1.8 mg/dL. HCVRNA and liver biopsies were performed prior to treatment, end of treatment (EOT) and 6 months after EOT for those who were HCV-RNA negative at EOT. Patients were followed prospectively after starting weekly pegylated-interferon alpha 2b 1.0 microg/kg (Schering-Plough, Kenilworth, NJ, USA). RESULTS: Among the 45 patients with recurrent HCV screened, 9 were eligible, including 8 men and 1 woman of average age 55 years. Eight patients were intolerant to the treatment requiring discontinuation within the first 3 months. Two patients developed a sustained response to HCV eradication. One patient who completed treatment has normal liver tests but is still viremic. CONCLUSIONS: Pegylated-interferon alpha 2b is poorly tolerated in liver transplant recipients with recurrent HCV and chronic renal failure. Larger, prospective studies are required to determine the optimum duration of treatment and the impact of treatment on histology and quality of life.

RESUMEN

Resource utilization is an important consideration when patients are selected for orthotopic liver transplantation (OLT). The Mayo Risk Score has been proposed to help predict optimum time for OLT. We assessed the relation between Mayo risk score, Child-Pugh score, and resource utilization and outcome after OLT for primary biliary cirrhosis. The mean Mayo risk score was greater in patients who died than in the survivors (8.6 +/- 1.4 v 7.1 +/- 1.8; P <.05). There was a positive correlation between Mayo risk score and the 4 resource variables studied (intraoperative blood requirements, time ventilated, and duration of intensive care unit and hospital stays). Patients with a Mayo risk score greater than 7.8 used almost twice the resources of patients with a risk score less than 7.8. A positive correlation also existed between Child-Pugh score and duration of hospital stay. The mean Child-Pugh score in patients who died was greater than that in survivors (10.7 +/- 2.0 v 8.5 +/- 2.8, P =.03). This study confirms that Mayo Risk score is an important predictor of resource utilization and outcome after OLT.
