Subjective parameters markedly limit the referral of transplantation candidates to liver transplant centres.

BACKGROUND & AIMS: Equality of access to organ transplantation is a mandatory public health requirement. Referral from a local to a university hospital and then registration on the national waiting list are the two key steps enabling access to liver transplantation (LT). Although the latter procedure is well defined using the Model for End-stage Liver Disease score that improves equality of access, the former is mostly reliant on the practices of referring physicians. The aim of this study was to clarify the factors determining this initial step. METHODS: This observational study included consecutive inpatients with cirrhosis of whatever origin in a cohort constituted between 2003 and 2008, using medical records and structured questionnaires concerning patient characteristics and the opinions of hospital clinicians. Candidates for LT were defined in line with these opinions. RESULTS: Four hundred and thirty-three patients, mostly affected by alcoholic cirrhosis, were included, 21.0% of whom were considered to be candidates for LT. Factors independently associated with their candidature were: physician empathy [odds ratio (OR) = 10.8; 95% CI: 4.0-29.5], adherence to treatment (OR = 16.6; 95% CI: 3.7-75.2), geographical area (OR = 6.8; 95% CI: 2.2-21.3) and the patient's physiological age (OR = 2.3; 95% CI: 1.1-4.7). CONCLUSIONS: Several subjective markers restrict the referral of patients from local hospitals to liver transplant centres. Their advancement to this second step is thus markedly weakened by initial subjectivity. The development of objective guidelines for local hospital physicians to assist them with their initial decision-making on LT is now necessary.

Prospective assessment of renal histopathological lesions in patients with end-stage liver disease: effects on long-term renal function after liver transplantation.

BACKGROUND & AIMS: The incidence of organic renal lesions in patients with end-stage liver disease is unknown. The goal of this study was to make a prospective evaluation of renal histological lesions in a group of unselected patients awaiting liver transplantation. METHODS: Sixty cirrhotic patients underwent a renal biopsy via the transjugular route. The potential effect of renal lesions on renal function was evaluated five years after transplantation. RESULTS: The yield of biopsies enabling satisfactory analysis was 77%, and no major complications occurred. Proteinuria>0.5 g/day was observed in only 8.7% of these patients, microscopic haematuria in 4.3%, creatinine levels>133 mmol/L (1.5mg/dl) in 10.9%, and Modification of the Diet in Renal Disease (MDRD) clearance<60 ml/min in 13.0%. Twenty-five patients (55.3%) had a morphological diagnosis of renal disease, 15 displayed IgA nephropathy and immunofluorescence testing showed that 12 had specific diabetic linear staining for IgG and albumin, of whom seven had associated histological lesions of diabetic nephropathy. Five years after liver transplantation, renal function had significantly deteriorated more in patients with initial diabetic lesions than in those with normal histology or IgA nephropathy alone. CONCLUSIONS: In patients with end-stage liver disease, IgA nephropathy and diabetic lesions were frequently found despite the absence of renal impairment and/or urinalysis anomalies. Our results strongly suggest that severe renal failure develops preferentially in liver transplant recipients with diabetes or carbohydrate intolerance, and that pre-existing arterial lesions may favour the nephrotoxicity of calcineurin inhibitors. Diabetes prior to transplantation needs to be strictly managed and requires a renal sparing immunosuppressive regimen after transplantation.

Might physicians be restricting access to liver transplantation for patients with alcoholic liver disease?

BACKGROUND/AIMS: In France, the most common cause of cirrhosis is excessive alcohol consumption. Post-transplant survival rates in patients with alcoholic liver disease (ALD) are at least as good as those seen with other indications. However, fewer of these patients are found on the waiting list. To understand the reasons for this discrepancy, it was decided to examine physicians' attitudes concerning the allocation of deceased donor liver allografts. METHODS: Using a standardized postal questionnaire, 1739 physicians were asked to allocate 100 liver transplants to two competing groups of patients who were equivalent except for the cause of their cirrhosis (i.e. alcohol-related or primary biliary cirrhosis). A composite score was then used to assess their attitude regarding the behavior of alcoholics and their responsibility for their illness. RESULTS: Among the 475 respondents (response rate: 27.3%), 55.2% allocated fewer than 50 transplants to ALD patients. This lower rate was independently associated with factors such as being a general practitioner (odds ratio [OR]=3.2, 95% confidence interval [95%CI]=1.8-5.9), a misinterpretation of ALD patients being equivalent to others (OR=1.8, 95%CI=1.1-3.0) or unfavorable attitudes regarding alcoholics (OR=4.0, 95%CI=1.7-9.5, to OR=126.8, 95%CI=34.0-472.1). CONCLUSIONS: Greater information and education of physicians may improve access to liver transplantation for ALD patients.
