We designed this study to define determinants of gastrointestinal complications after cardiac surgery. From January 1992 through December 2000, 11,058 patients underwent cardiac surgery on cardiopulmonary bypass at our institution. Data were prospectively collected and univariate and multivariate analyses conducted. A total of 147 gastrointestinal complications occurred in 129 patients (129/11,058; 1.2%) including gastroesophagitis (18, 12.2%), upper gastrointestinal hemorrhage (42, 28.6%), perforated peptic ulcer (7, 4.7%), cholecystitis (10, 6.8%), pancreatitis (13, 8.8%), intestinal ischemia (17, 11.5%), colitis (18, 12.2%), diverticulitis (5, 3.4%), intestinal occlusion (2, 1.1%), lower gastrointestinal hemorrhage (1, 0.7%), and mixed gastrointestinal complications (14, 9.5%). Patients with gastrointestinal complications were significantly older and had significantly higher comorbidity (unstable angina, chronic renal failure, and peripheral vascular disease), morbidity (prolonged mechanical ventilation, intraaortic balloon pumping, bleeding, acute renal failure, stroke, and infection), and mortality rates (22.5% vs 4%, P < 0.0001). They also had longer cardiopulmonary bypass times and higher valvular surgery rates. Multivariate analysis identified 6 independent predictors for gastrointestinal complications: prolonged mechanical ventilation (odds ratio [OR], 5.5), postoperative renal failure (OR, 4.2), sepsis (OR, 3.6), valve surgery (OR, 3.2), preoperative chronic renal failure (OR, 2.7), and sternal infection (OR, 2.4). Factors such as mechanical ventilation, renal failure, and sepsis are the stronger predictors for GI complications, causing splanchnic hypoperfusion, hypomotility, and hypoxia. Furthermore, excessive anticoagulation after valve replacement may lead to GI hemorrhage. Valve surgery, often requiring anticoagulation, increases bleeding. Monitoring mechanical ventilation and hemodynamic parameters, adopting early extubation and mobilization measures, preventing infections, and strictly monitoring renal function and anticoagulation may prevent catastrophic abdominal complications.

Chronic renal failure needs substitutive treatment such as haemodialysis and peritoneal dialysis for the patient to survive. Kidney transplantation (KTx) improves survival of the patient with chronic renal failure. Since the first KTx, performed by Merrill in Boston in 1959, advances in medical therapy, immunosuppressive therapy and refinements in surgical technique have improved the quality of life of the transplant patient. We present a review of the incidence, diagnosis and therapy of surgical complications after KTx reported in the literature and a retrospective analysis of 297 consecutive cadaveric donor kidney transplants done in our institution from September 1993 to September 2002. Vascular complications represent 5-10% of postoperative complications. Our experience showed an incidence of 1.7% renal artery thrombosis, 1.4% renal vein thrombosis, 1.7% renal artery stenosis, 1.4% arterial rupture due to fungal arteritis, 0.7% spontaneous graft ruptures and 12% lymphoceles. Urological complications account for 10-15% of postoperative complications. In our series we found an incidence of 7.4% urinary leakage, 2.7% urinary obstruction and 3% urinary reflux. Gastrointestinal complications represent 16% of postoperative complications. Our series showed 1% pancreatitis with an overall mortality of 33% and an incidence of 1.7% intestinal perforations. Surgical complications still represent a challenge that increments morbidity and mortality among kidney transplant recipients. Data shown may offer some guidance on how to deal with early and late post-transplant surgical complications.

We reviewed our experience with simultaneous single incision bilateral native nephrectomy and renal transplantation in 11 patients (Group 1), compared to seven recipients who underwent staged laparoscopic bilateral nephrectomy followed by kidney transplantation (Group 2). Mean age, donor source, sex, cause of ESRD, and specimen size were similar in both groups (P=0.1). All Group 2 patients and 9 of 11 Group 1 patients had autosomal-dominant polycystic kidney disease. Perioperative Group 1 complications included: bowel injury, transplant urine leak, necrotic pancreatitis, delayed bowel movement, and severe shoulder pain secondary to diaphragmatic irritation. Seven (63.6%) Group 1 patients required an additional surgical procedure: midline incisional hernia, repair ureteral fistula, and repair enterocutaneous fistula. One Group 1 patient lost his graft secondary to bowel injury and intra-abdominal sepsis. No major complications, reoperations, or graft loss occurred in Group 2. For simultaneous bilateral native nephrectomy and kidney transplantation, over 60% of patients required an additional surgical procedure. Laparoscopic bilateral nephrectomy followed by kidney transplantation is a safe and feasible alternative.

Autosomal-dominant polycystic kidney disease is an inherited disorder characterized by multiple cysts in kidneys and other organs. A 63-year-old man was evaluated for the etiology of recurrent pancreatitis and chronic renal failure. Multiple cysts of kidneys, liver, and pancreas and pancreas divisum was diagnosed. Pancreatitis should be included in the differential diagnosis of abdominal pain in patients with ADPKD. Pancreas divisum may be a predisposing factor for acute pancreatitis in these patients.

An 81-year-old man, with chronic renal failure due to chronic glomerulonephritis on maintenance hemodialysis (HD) for 4.5 years, was admitted to our hospital because of rapidly developing hyperglycemia and hypertension. He had been under good control on HD with no history of hyperglycemia. One month prior to admission he felt thirsty and generally fatigued, but did not inform medical staff of his symptoms. We diagnosed him as suffering from autoimmune pancreatitis (AIMP) associated with secondary diabetes mellitus, according to the typical feature of AIMP on endoscopic retrograde cholangiopancreatography and an elevated level of serum immunoglobulin G4 (IgG4). He was treated with insulin and a corticosteroid, following which, the diffuse narrowing of the main pancreatic duct improved and his serum IgG4 level reduced. AIMP is a rare but important complication in HD patients that requires prompt diagnosis and treatment; we are therefore reporting on a unique complication in a chronic HD patient.

TREATMENT OF ARTERIAL HYPERTENSION - Blood pressure (BP) should be regularly measured in all patients with CKD (Strength of Recommendation C). - BP control and proteinuria reduction delay progression of CKD (Strength of Recommendation A) and reduce cardiovascular risk (Strength of Recommendation C). Thus, control of both factors should be the treatment objective. - The BP target in patients with CKD should be < 130/80 mmHg, and 125/75 mmHg if proteinuria is > 1 g/24 hours (Strength of Recommendation A). - Lifestyle changes should be made: low-sodium diet (less than 100 mEq/day of sodium or 2.4 g/day of salt); weight reduction if patient is overweight (body mass index 20-25 kg/m2); regular aerobic physical exercise and moderate alcohol intake for BP control and prevention of cardiovascular risk (Strength of Recommendation A). - The choice of the antihypertensive drug in patients with CKD depends on the etiology of CKD, cardiovascular risk, or presence of clinical or subclinical cardiovascular disease (Strength of Recommendation A). - Two or more antihypertensive drugs are usually required to control blood pressure in patients with CKD (Strength of Recommendation B), and will frequently include a diuretic, which in stages 4-5 should be a loop diuretic (Strength of Recommendation B). - Renin-angiotensin-aldosterone system (RAAS) inhibitors are first choice drugs in patients with diabetic nephropathy, patients with non-diabetic nephropathy with a protein/creatinine ratio higher than 200 mg/g, and patients with heart failure (Strength of Recommendation A). The combination of ACEIs and ARBs is indicated for reducing proteinuria that remains high despite treatment with a RAAS inhibitor, provided potassium levels do not exceed 5.5 mEq/L (Strength of Recommendation B). - When RAAS blockers are started or their dose is changed in patients with advanced CKD, kidney function and serum potassium levels should be monitored at least after 1-2 weeks. DIAGNOSIS AND TREATMENT OF DYSLIPIDEMIA - A complete evaluation of the lipid profile including total cholesterol, LDL-C, HDL-C, and triglycerides should be performed in any patient with CKD at baseline and at least annually (Strength of Recommendation B). - In patients with stage 4-5 CKD and LDL-C >or= 100 mg/dL, treatment to decrease levels to < 100 mg/dL should be considered because of their high CV risk. This reduction is recommended in secondary prevention and in primary prevention in diabetic patients. Lipid-lowering treatment is recommended in all other patients, although no evidence showing its benefits is available yet (Strength of Recommendation C). - In patients with stage 4-5 CKD and triglyceride levels >or= 500 mg/dL which are not corrected by treating the underlying cases, treatment with triglyceride-lowering drugs may be considered to reduce the risk of pancreatitis. However, treatment with fibrates should be used with caution, and these drugs should not be associated to statins due to the risk of rhabdomyolysis (Strength of Recommendation C). There is little experience on the efficacy and safety of omega-3 fatty acids for the treatment of hypertriglyceridemia in patients with grade 4-5 CRF, but they may be considered a possibly safer alternative to fibrates (Strength of Recommendation C). SMOKING - Smoking is a cardiovascular risk factor and a risk factor for progression of kidney disease in patients with CRF (Strength of Recommendation B). - Use of active measures to achieve smoking cessation is recommended in patients with CRF (Strength of Recommendation C). HOMOCYSTEINE - Hyperhomocysteinemia has been postulated as a cardiovascular risk factor in the general population and in kidney patients, but the available evidence is not consistent. - There is no evidence that vitamin therapy decreases cardiovascular risk in patients with CRF, and recommendation of routine vitamin measurement and start of vitamin therapy to reduce cardiovascular risk in these patients is therefore questionable (Strength of Recommendation B). LEFT VENTRICULAR HYPERTROPHY - Left ventricular hypertrophy (LVH) is a cardiovascular risk factor in patients with CRF (Strength of Recommendation B). - It is advisable to perform an echocardiogram at baseline and every 12-24 months and to consider treatments allowing for LVH regression (Strength of Recommendation C). The approach to LVH should be early and multifactorial because its reversibility is limited once established (Strength of Recommendation C). - RAAS blockade with ACEIs or ARBs partially reverts LVH in patients with CRF (Strength of Recommendation B). ANTI-PLATELET AGGREGATION - Because of the high cardiovascular risk in patients with CKD, anti-platelet aggregant therapy, especially low-dose aspirin, would be indicated in patients with type 2 diabetes as primary prevention, and in all patients with CKD as secondary prevention. There is however no evidence of the benefits of anti-platelet aggregant therapy in primary prevention in patients with CKD, particularly in stages 4-5; indication for treatment in this situation should therefore be individualised because of its greater risk of bleeding. - Adequate good blood pressure control should previously be achieved to minimise the risk of haemorrhagic stroke (Strength of Recommendation C).

In our previous studies, WBN/KobSlc was characterized as a rat strain in which only males began to develop pancreatitis, and then presented with diabetic symptoms. In the course of studying their pancreatic inflammation, we detected molar caries in prediabetic males feeding on a standard diet (CRF-1) widely used for experimental animals. The purpose of this study is to confirm whether the WBN/KobSlc strain is caries-susceptible to the diet reported to be non-cariogenic, and to examine the effect of a prediabetic condition on their dental caries. For a morphological study, 25 male WBN/KobSlc rats aged 3.2-7.8 months and 24 females of the same strain aged 3.3-6.6 months were used, along with 10 males and 10 females of 8.2-month-old F344 rats. Marked dental caries were detected in the mandibular molars of male and female WBN/KobSlc rats regardless of pancreatitis, although no similar changes were observed in any teeth of the F344 strain fed the same diet. Soft X-ray examination revealed that the caries began in the crown and progressed horizontally and vertically, and that a severe radiolucent lesion extensively expanded to the entire crown, corresponding to a macroscopically deleted molar. The caries had gradually developed mainly in the second mandibular molar from more than 3.5 months of age, while none were seen in any rats before that time. The WBN/KobSlc rats were caries-susceptible even to the standard laboratory diet, and pancreatitis was not directly associated with the onset of dental caries in this strain.

IgG4 has been implicated in a diverse set of complex pathologies - e.g. autoimmune pancreatitis (AIP), idiopathic membranous nephropathy - and carries unique features including lack of activation of the classical complement pathway and a dynamic Fab-arm exchange. We recently showed that the rheumatoid factor (RF)-like activity of IgG4 is achieved through a hitherto unknown, Fc-Fc (and not Fab-Fc as is the case in classical RF; CRF) interaction; hence the name, novel RF (NRF). Here, we further explore the resemblance/difference between CRF and NRF. As heterophilic interactions of human IgM RF (CRF) are well known, we checked whether this is the case for IgG4. Human IgG4 showed variable reactivity to animal IgGs: reacting intensely with rabbit and mouse IgGs, but weakly with others. The binding to rabbit IgG was not through the Fab (as in CRF) but via the Fc piece, as was recently shown for human IgG (NRF). This binding correlates with the IgG4 concentration per se and could therefore be of diagnostic usage and incidentally explain some observed interferences in biological assays. In conclusion, here is defined a novel heterophilic antibody interaction and is established the universality of the unique Fc-Fc binding, both involving IgG4.

Fungal infections after kidney transplantation are a major cause of morbidity and mortality, and Candida infection of the pancreas is considered an infrequent but important agent in necrotizing pancreatitis. We report the case of a 43-year-old Caucasian patient who underwent simultaneous pancreas-kidney transplantation because of diabetes type I, and chronic renal failure with peritoneal dialysis. The postoperative course was complicated by acute pancreatitis due to the thrombosis of the splenic artery of the graft, the subsequent acute rupture of the external iliac artery caused by fungal arteritis (Candida glabrata), and peritonitis a few days later caused by sigmoid perforation with detection of Candida glabrata infection of the resected intestinal tract. The present case remarks that awareness and prevention of fungal infection are major issues in the transplant field. Important information can be added by systematic culture of conservation perfusates but, probably, the best way for early recognition of a critical level of infectious risk remains the routine application of the colonization index screening. In cases of positive results, preemptive antifungal therapy could be warranted.

A 77-year-old man with an infrarenal abdominal aortic aneurysm was referred with a complex medical history including pancreatitis, chronic renal failure, atrial fibrillation, and a cerebral infarction. He also had a history of atherosclerosis obliterans, treated with a vascular bypass using an 8-mm prosthetic graft 9 years previously. His complicated anatomy, including a small access route and a large common iliac artery, suggested usage of Powerlink, a bifurcated stent graft through the previously placed graft, as an access route. The patient was discharged from the hospital with a type III endoleak, which was completely resolved 5 months after discharge.
