Several drugs have been implicated as causes of acute pancreatitis. This report presents four patients, three with lupus nephritis and one with membranous glomerulopathy, who developed acute pancreatitis while being treated with corticosteroids alone or in combination with azathioprine. Two of the reported patients died with a hemorrhagic pancreatitis and one of the patients developed a pancreatic pseudocyst. The pathogenesis of corticosteroid and/or azathioprine-induced pancreatitis is discussed.

Pediatric cases of systemic lupus erythematosus with an unfavorable outcome (terminal renal failure requiring chronic hemodialysis, or death) assembled during a retrospective multicenter study of pediatric SLE in the Paris metropolitan area were analyzed. Seven patients (6 girls, 1 boy) were entered into a chronic hemodialysis program. Four had diffuse proliferative glomerulonephritis, the pattern of glomerular disease classically responsible for end-stage renal failure. The other three patients had membranous glomerulonephritis with active segmental lesions, a form of glomerulopathy whose severe prognosis deserves to be emphasized. Nine other patients (8 girls, 1 boy) died. In six patients, death occurred as a result of a flare with malignant hypertension and progressive renal failure (1 case), pancreatitis (1 case), encephalopathy (2 cases) or cardiomyopathy (2 cases). An infectious disease (tuberculosis, mumps) was apparently the cause of the two cases of encephalopathy. One girl died as a result of a hemorrhagic syndrome with a cerebral hematoma. Two other girls died at home. Overall, among 111 children with SLE 14% had an unfavorable outcome. Sex and age at onset seemed to have no bearing on prognosis. Patients with renal involvement were apparently more likely to have an unfavorable outcome. Lastly, although the influence of ethnic origin is unproven, children living in foreign countries of French overseas territories, but treated in France have an increased risk for unfavorable outcomes.

Membranous glomerulonephropathy can be experimentally induced in rats, but spontaneous cases have been rarely reported. In this report, we present a typical case of spontaneous membranous glomerulonephropathy in a rat. A male Hatano low-avoidance (LAA) strain rat had a tumor mass on the right auricle, and was sacrificed at 41 weeks of age. Urinary screening by reagent strips revealed intense proteinuria. Histological tests revealed frequent presence of irregularly sized eosinophilic hyaline materials on the capillary wall and in the mesangium of renal glomeruli. Immunofluorescence revealed granular deposits of IgG, IgM, and C3 in the glomeruli. Subepithelial dense deposits were observed by electron microscopy accompanied by podocyte foot process effacement and occasional irregular thickening of the glomerular basement membrane. The rat also developed chronic lymphocytic pancreatitis, and the tumor mass on the right auricle was diagnosed as a fibrosarcoma. Screening tests for antibodies against major infectious agents and antinuclear antibody were negative. Western blot and indirect immunofluorescence analyses suggested the presence of an autoantibody against the pancreatic component. The glomerulopathy was considered an early stage of membranous glomerulonephropathy.

Atherosclerosis is strongly associated with dyslipoproteinaemia, and especially with increasing concentrations of low-density lipoprotein and decreasing concentrations of high-density lipoproteins. Its association with increasing concentrations of plasma triglyceride is less clear but, within the mixed hyperlipidaemias, dysbetalipoproteinaemia (Fredrickson type III hyperlipidaemia) has been identified as a very atherogenic entity associated with both premature ischaemic heart disease and peripheral arterial disease. Dysbetalipoproteinaemia is characterized by the accumulation of remnants of chylomicrons and of very low-density lipoproteins. The onset occurs after childhood and usually requires an additional metabolic stressor. In women, onset is typically delayed until menopause. Clinical manifestations may vary from no physical signs to severe cutaneous and tendinous xanthomata, atherosclerosis of coronary and peripheral arteries, and pancreatitis when severe hypertriglyceridaemia is present. Rarely, mutations in apolipoprotein E are associated with lipoprotein glomerulopathy, a condition characterized by progressive proteinuria and renal failure with varying degrees of plasma remnant accumulation. Interestingly, predisposing genetic causes paradoxically result in lower than average cholesterol concentration for most affected persons, but severe dyslipidaemia develops in a minority of patients. The disorder stems from dysfunctional apolipoprotein E in which mutations result in impaired binding to low-density lipoprotein (LDL) receptors and/or heparin sulphate proteoglycans. Apolipoprotein E deficiency may cause a similar phenotype. Making a diagnosis of dysbetalipoproteinaemia aids in assessing cardiovascular risk correctly and allows for genetic counseling. However, the diagnostic work-up may present some challenges. Diagnosis of dysbetalipoproteinaemia should be considered in mixed hyperlipidaemias for which the apolipoprotein B concentration is relatively low in relation to the total cholesterol concentration or when there is significant disparity between the calculated LDL and directly measured LDL cholesterol concentrations. Genetic tests are informative in predicting the risk of developing the disease phenotype and are diagnostic only in the context of hyperlipidaemia. Specialised lipoprotein studies in reference laboratory centres can also assist in diagnosis. Fibrates and statins, or even combination treatment, may be required to control the dyslipidaemia.

Pancreas transplantation aims to restore physiologic normoglycemia in diabetic patients with glomerulopathy and avoid or delay the onset of diabetic retinopathy and arteriopathy. Simultaneous pancreas-kidney transplant is the most common approach, using a cadaveric pancreas donation in conjunction with either cadaveric or live donor renal transplant. Alternative techniques include pancreas after kidney transplant, in which the pancreas transplant is performed some years after renal transplant. Pancreas transplant alone is utilized rarely in diabetic patients with compensated renal function. Pancreas grafts have vascular and enteric connections that vary in their anatomic approach, and understanding of this is critical for imaging with ultrasonography, computed tomography, or magnetic resonance imaging. Imaging techniques are directed to display the pancreatic transplant arterial and venous vasculature, parenchyma, and intestinal drainage pathway. Critical vascular information includes venous thrombosis (partial or complete), arterial occlusion, or aneurysm. Parenchymal abnormalities are nonspecific and occur in pancreatitis, graft rejection, and subsequent graft ischemia. Peripancreatic fluid collections include hematoma/seroma, pseudocyst, and abscess. The latter two are related to pancreatitis, duct disruption, or leak from the duodenojejunostomy. An understanding of transplant anatomy and complications will lead to appropriate use of imaging techniques to diagnose or exclude important complications.
