Long term follow up of severely ill patients who underwent urgent cardiac transplantation.

OBJECTIVE--To assess long term survival (> 5 years) and quality of life in severely ill patients referred for urgent cardiac transplantation. SETTING--Tertiary referral centres: before transplantation at the National Heart Hospital (late 1984 to end 1986); after transplantation at Harefield Hospital. SUBJECTS--Eighteen patients (15 men; three women) who had required intensive support in hospital before cardiac transplantation and were alive at short term follow up. INTERVENTIONS--Intravenous infusions of cardiac drugs (mean 2.2 infusions), intravenous diuretics (17 patients), and many other drugs before transplantation. Intra-aortic balloon counterpulsation (four patients), temporary pacing (two), and resuscitation from cardiac arrest (three). Patients had specialised nursing care on a medical intensive care unit in almost every case. MAIN OUTCOME MEASURES--Long term survival in patients after urgent cardiac transplantation and perceived quality of life. RESULTS--Of 18 patients who were alive at short term follow up (mean (range) 19.4 (10-33) months), 14 were still alive in 1992 (69 (61-83) months). Ten still worked full time, and 11 reported no restrictions in their daily activities. Three of four patients who died in the intervening period survived > 5 years after transplantation. Overall, 17 of 18 patients survived at least 5 years. CONCLUSIONS--In severely ill patients who undergo urgent cardiac transplantation and survive in the short term, long term (5-7 year) survival and quality of life seem good.     

Management of uraemic pericarditis.

Of 250 patients undergoing haemodialysis from 1967 to 1974 17 presented with uraemic pericarditis. Seven of these patients who had been transferred early enough to peritoneal dialysis treatment were cured without pericardiectomy (mean survival 18 months (range 6-36); no deaths). Only one patient was cured from his pericarditis by "aggressive haemodialysis." In seven out of 10 patients treated with haemodialysis, pericardiectomy finally had to be performed because of pericardial tamponade (postoperative survival 20 months (range 8-36); one death). Two patients died from pericardial tamponade before surgery. In patients with evidence of uraemic pericarditis frequent peritoneal dialysis with high fluid withdrawal is the treatment of choice, but in cardiac tamponade pericardiectomy should follow a preoperative pericardiocentesis with limited fluid aspiration. Of possible significance in the aetiology of pericarditis were the findings that 10 of the 17 patients had hypertension with cardiac enlargement and that 14 presented with evidence of underdialysis, possibly due to the reuse of dialysis components.     

Percutaneous cryoablation for the treatment of medically inoperable stage I non-small cell lung cancer

Background

To evaluate the midterm results of percutaneous cryoablation for medically inoperable stage I non-small cell lung cancer.

Methodology/Principal Findings

Between January 2004 and June 2010, 160 patients underwent computer tomography guided percutaneous cryoablation for lung tumors at our institution. Of these patients, histologically proven stage I lung cancer patients with more than one year of follow-up, were retrospectively reviewed. All of these patients were considered to be medically inoperable with Charlson comorbidity index of 3 or greater. Follow-up was based primarily on computed tomography. There were 22 patients with 34 tumors who underwent 25 sessions of cryoablation treatment. Complications were pneumothoraces in 7 treatments (28%, chest tube required in one treatment), and pleural effusions in 8 treatments (31%). The observation period ranged from 12–68 months, average 29±19 months, median 23 months. Local tumor progression was observed in one tumor (3%). Mean local tumor progression-free interval was 69±2 months. One patient died of lung cancer progression at 68 months. Two patients died of acute exacerbations of idiopathic pulmonary fibrosis which were not considered to be directly associated with cryoablation, at 12 and 18 months, respectively. The overall 2- and 3-year survivals were 88% and 88%, respectively. Mean overall survival was 62±4 months. Median overall survival was 68 months. The disease-free 2- and 3-year survivals were 78% and 67%, respectively. Mean disease-free survival was 46±6 months. Pulmonary function tests were done in 16 patients (18 treatments) before and after cryoablation. Percentage of predicted vital capacity, and percentage of predicted forced expiratory volume in 1 second, did not differ significantly before and after cryoablation (93±23 versus 90±21, and 70±11 versus 70±12, respectively).

Conclusions/Significance

Although further accumulation of data is necessary regarding efficacy, cryoablation may be a feasible option in medically inoperable stage I lung cancer patients.     

Cardiac transplantation in 150 patients at Stanford University.

A total of 150 patients underwent cardiac transplantation at Stanford between January 1968 and August 1978. Sixty-two patients were alive at the end of this period, when the expected one-year survival rate was 70%, with an attrition rate of roughly 5% thereafter. Changes in postoperative managment resulting from continuing research contributed to improved survival rates. The results are equal or superior to those for recipients of renal transplants from unrelated donors. Major centres that have suitably trained staff and appropriate facilities for cardiac surgery should perhaps reconsider cardiac transplantation as an alternative to death in certain patients.     

High survival rate of 43% in out-of-hospital cardiac arrest patients in an optimised chain of survival

Aims

Survival to hospital discharge after out-of-hospital cardiac arrest (OHCA) varies widely. This study describes short-term survival after OHCA in a region with an extensive care path and a follow-up of 1 year.

Methods

Consecutive patients ≥16 years admitted to the emergency department between April 2011 and December 2012 were included. In July 2014 a follow-up took place. Socio-demographic data, characteristics of the OHCA and interventions were described and associations with survival were determined.

Results

Two hundred forty-two patients were included (73 % male, median age 65 years). In 76 % the cardiac arrest was of cardiac origin and 52 % had a shockable rhythm. In 74 % the cardiac arrest was witnessed, 76 % received bystander cardiopulmonary resuscitation and in 39 % an automatic external defibrillator (AED) was used. Of the 168 hospitalised patients, 144 underwent therapeutic procedures. A total of 105 patients survived until hospital discharge. Younger age, cardiac arrest in public area, witnessed cardiac arrest, cardiac origin with a shockable rhythm, the use of an AED, shorter time until return of spontaneous circulation, Glasgow Coma Scale (GCS) ≥13 during transport and longer length of hospital stay were associated with survival. Of the 105 survivors 72 survived for at least 1 year after cardiac arrest and 6 patients died.

Conclusion

A survival rate of 43 % after OHCA is achievable. Witnessed cardiac arrest, cardiac cause of arrest, initial cardiac rhythm and GCS ≥13 were associated with higher survival.     

Natural course of penicillamine nephropathy: a long term study of 33 patients

To elucidate the natural course of the nephropathy associated with penicillamine and thereby facilitate its clinical management 33 patients with rheumatoid arthritis who developed proteinuria during treatment with oral penicillamine were studied in detail throughout their renal illness. Renal biopsies were performed, and creatinine clearance and proteinuria were measured serially for 74 months (range 16-148 months). Fourteen patients developed proteinuria within six months after the start of treatment and 27 within 12 months. When treatment was stopped the proteinuria reached a median peak of 4·2 g/24 h (range 0·3-15·0 g/24 h) at one month (range 0-7 months) before resolving spontaneously by six months (12 patients), 12 months (21), or 18 months (29). In all patients but one, who developed carcinoma of the renal pelvis, proteinuria resolved by 21 months and its median duration was eight months. The median first and last measurements of creatinine clearance showed no appreciable change (80 ml/min and 78 ml/min), and no patient died from or needed treatment for renal failure. The HLA-B8 or HLA-DR3 alloantigen, or both, were identified in 10 patients. Renal biopsy specimens showed membranous glomerulonephritis in 29 patients, minimal change nephropathy in two, and electron dense deposits in the mesangial regions in two.In all the patients whose nephropathy was due solely to treatment with penicillamine the proteinuria resolved completely when the drug was withdrawn; renal function did not deteriorate, and corticosteroids were unnecessary.     

Myocardial Infarction: A Five-Year Follow-up of Patients

Patients with acute myocardial infarction (2,020) admitted to coronary care units (CCU) in Utah were studied for five years. Of these, 1,641 (81.4 percent) survived to leave the hospital. The male to female ratio was 3.5:1. At four months, one year and yearly thereafter from the date of admission to CCU, patients were mailed follow-up questionnaires. Cause of death was obtained from autopsy reports and death certificates. Patients were grouped yearly by the number of cardiac symptoms reported. Of patients discharged whose cases were followed, 925 (61.9 percent) were alive after five years. Reinfarction was the major cause of death in the hospital; however, during follow-up only 36.8 percent of deaths were attributable to myocardial infarction. At follow-up after a year, fewer cardiac symptoms were reported by patients who survived to the fifth year of follow-up than by patients who did not. Women were older and showed a higher death rate during follow-up. Increasing age was found to be a determining factor in long-term mortality after acute myocardial infarction.     

Surgical Aspects of Bacterial Endocarditis

Forty patients with a previous history of bacterial endocarditis were treated surgically between December 1967 and August 1971. Of 28 patients who had elective valve replacements there were four hospital deaths and one late death. Seven patients underwent emergency operation for intractable heart failure before completion of antibiotic treatment, six survived operation and there was one late death. Six patients had operations for infection on pre-existing valve substitutes, of whom three were treated as emergencies. There were two hospital and no late deaths. 78% of all patients were alive and well four years to nine months after operation.These results confirm that in addition to elective valve replacement surgery has an important role both in the treatment of intractable heart failure during the infective stage of bacterial endocarditis and in the eradication of infection on cardiac prostheses.     

Survival Rates of Patients Treated by Home and Hospital Dialysis and Cadaveric Renal Transplantation

Of 109 patients admitted to the renal failure programme of the Royal Free Hospital 80·7% were surviving after six years. For patients on home dialysis the four-year rate was 86·2%, more deaths occurring in women than in men. The short-term survival rate of all patients was high—namely, 96·3% at six months and 94·4% at 12 months. Hence large increases in the rate of acceptance of patients as well as successful transplantation are necessary to balance acceptance and loss from this programme.     

Acute Ethanol Exposure Increases the Susceptibility of the Donor Hearts to Ischemia/Reperfusion Injury after Transplantation in Rats

Background

Many donor organs come from youths involved in alcohol-related accidental death. The use of cardiac allografts for transplantation from donors after acute poisoning is still under discussion while acute ethanol intoxication is associated with myocardial functional and morphological changes. The aims of this work were 1) to evaluate in rats the time-course cardiac effects of acute ethanol-exposure and 2) to explore how its abuse by donors might affect recipients in cardiac pump function after transplantation.

Methods

Rats received saline or ethanol (3.45 g/kg, ip). We evaluated both the mechanical and electrical aspects of cardiac function 1 h, 6 h or 24 h after injection. Plasma cardiac troponin-T and glucose-levels were measured and histological examination of the myocardium was performed. In addition, heart transplantation was performed, in which donors received ethanol 6 h or 24 h prior to explantation. Graft function was measured 1 h or 24 h after transplantation. Myocardial TBARS-concentration was measured; mRNA and protein expression was assessed by quantitative real-time PCR and Western blot, respectively.

Results

Ethanol administration resulted in decreased load-dependent (−34±9%) and load-independent (−33±12%) contractility parameters, LV end-diastolic pressure and elevated blood glucose levels at 1 h, which were reversed to the level of controls after 6 h and 24 h. In contrast to systolic dysfunction, active relaxation and passive stiffness are slowly recovered or sustained during 24 h. Moreover, troponin-T-levels were increased at 1 h, 6 h and 24 h after ethanol injection. ST-segment elevation (+47±10%), elongated QT-interval (+38±4%), enlarged cardiomyocyte, DNA-strand breaks, increased both mRNA and protein levels of superoxide dismutase-1, glutathione peroxydase-4, cytochrome-c-oxidase and metalloproteinase-9 were observed 24 h following ethanol-exposure. After heart transplantation, decreased myocardial contractility and relaxation, oxidative stress and altered protein expression were observed.

Conclusions

These results demonstrate acute alcohol abuse increases the susceptibility of donor hearts to ischemia/reperfusion in a rat heart transplant model even though the global contractile function recovers 6 h after ethanol-administration.     

One Year's Experience in a Ministry of Health Dialysis Centre

A 10-bed dialysis unit, opened at the London Hospital in 1968, admitted 37 patients during its first year of operation. The aims of the unit were to prepare patients for renal transplantation and to provide instruction for dialysis treatment at home. A total of 2,012 days were spent in hospital, the average intervals between admission, the first dialysis, and discharge being 23·8 and 20 days, respectively. The overall number of readmissions was 1·5 per patient. These figures, together with the increasing number of patients accepted for such treatment, indicate the considerable number of supporting hospital beds, as well as medical and technical staff, required to maintain a dialysis unit.     

Patients with aortic stenosis referred for TAVI: treatment decision, in-hospital outcome and determinants of survival

Aims

To assess treatment decision and outcome in patients referred for transcatheter aortic valve implantation (TAVI) in addition to predictive factors of mortality after TAVI.

Methods

Three-centre prospective observational study including 358 patients. Endpoints were defined according to the Valve Academic Research Consortium.

Results

Of the 358 patients referred for TAVI, TAVI was performed in 235 patients (65%), surgical aortic valve replacement (AVR) in 24 (7%) and medical therapy (MT) in 99 (28%). Reasons to decline TAVI in favour of AVR/MT were patient preference (29%), peripheral vascular disease (15%) and non-severe aortic stenosis (11%). The logistic EuroSCORE was significantly higher in patients who underwent TAVI and MT in comparison with those undergoing AVR (19 vs. 10%, p = 0.007). At 30 days, all-cause mortality and the combined safety endpoint were 9 and 24% after TAVI and 8 and 25% after AVR, respectively. All-cause mortality was significantly lower in the TAVI group compared with the MT group at 6 months, 1 year and 2 years (12% vs. 22%, 21% vs. 33% and 31% vs. 55%, respectively, p < 0.001). Multivariable analysis revealed that blood transfusion (HR: 1.19; 95% CI: 1.05–1.33), pre-existing renal failure (HR: 1.18; 95% CI: 1.06–1.33) and STS score (HR: 1.06; 95% CI: 1.02–1.10) were independent predictors of mortality at a median of 10 (IQR: 3–23) months after TAVI.

Conclusions

Approximately two-thirds of the patients referred for TAVI receive this treatment with gratifying short- and long-term survival. Another 7% underwent AVR. Prognosis is poor in patients who do not receive valve replacement therapy.     

Statins Do Not Reduce Atrial Fibrillation After Cardiac Valvular Surgery: A Single Centre Observational Study

Introduction

Statins may theoretically reduce postoperative atrial fibrillation (AF) in patients after cardiac valvular surgery due to preservation of endothelial function and anti-ischaemic, anti-inflammatory and anti-remodelling effects.

Methods

Two hundred seventy-two patients who underwent cardiac workup and subsequently cardiac valvular surgery without AF and concomitant coronary artery bypass grafting (CABG) at our hospital were selected. Preoperative drug use and postoperative AF were recorded. AF was defined as any episode of AF longer than 10 s. In addition, results from echocardiography and blood samples were retrieved.

Results

Baseline characteristics were as follows: mean age was 65 ± 11 years, 142 (52%) patients were male, 189 (70%) had undergone aortic valve surgery and the mean left ventricular ejection fraction was 57 ± 12%. Statins were used by 79 patients (29%). Statin users, more often, had a prior percutaneous coronary intervention (25% vs 9%, p < 0.001) or CABG (24% vs 4%, p < 0.001), diabetes mellitus (22% vs 5%, p < 0.001) and more often used β-blockers (51% vs 24%, p < 0.001). Patients in the non-statin group more often had surgery on more than one valve (10% vs 3%, p = 0.043) and had a higher cholesterol level (222 ± 48 vs 190 ± 43 mg/dl, p < 0.001). Postoperative AF occurred in 54% (43/79) of the patients with and in 55% (106/193) of the patients without statins (p = 0.941). There was also no difference in the timing of onset of AF or duration of hospital stay.

Conclusion

In this observational study, statin use was not associated with a reduced incidence of AF in patients after cardiac valvular surgery.     

Prognostic Impact of 9-Month High-Sensitivity C-Reactive Protein Levels on Long-Term Clinical Outcomes and In-Stent Restenosis in Patients at 9 Months after Drug-Eluting Stent Implantation

Introduction

The level of 9-month high-sensitivity C-reactive protein (hsCRP) in predicting cardiovascular outcomes is scanty in patients at 9 months after receiving drug-eluting stent (DES) implantations. This study aims to evaluate the relationship between 9-month follow-up hsCRP levels and long-term clinical outcomes in patients at 9 months after receiving DES.

Methods

A total of 1,763 patients who received 9-month follow-up angiography were enrolled and grouped according to hsCRP level 9 months after the DES implantation: group I (718 patients, hsCRP<1.0 mg/L), group II (639 patients, 1.0≦hsCRP≦3.0 mg/L), and group III (406 patients, hsCRP>3.0 mg/L).

Results

Group III patients had a lower cardiovascular event-free survival rate than group I or II patients during a follow-up of 64±45 months (64.5% vs. 71.6% vs. 72.8%, respectively, p = 0.012). Multivariate analysis showed that a follow-up hsCRP level <3.0 mg/L was an independent predictor of a major adverse cardiovascular event (cardiac death, reinfarction, target lesion revascularization, stenting in a new lesion, or coronary bypass surgery). Group III patients had a higher restenosis rate (11.3% vs. 5.8% vs. 6.6%, respectively, p = 0.002) and loss index (0.21±0.32 vs. 0.16±0.24 vs. 0.18±0.28, respectively, p = 0.001) than group I or II patients in 9-month follow-up angiography.

Conclusions

A high 9-month follow-up hsCRP level is an independent predictor of long-term clinical cardiovascular outcomes in patients at 9 months after DES implantation. It is also associated with a higher restenosis rate, larger late loss and loss index at 9 months after DES implantation.     

Two decades of aortic coarctation treatment in children; evaluating techniques

ObjectiveThis study focuses on the evolution of treatment techniques for aortic coarctation in children and assesses long-term morbidity.MethodsThis retrospective cohort study evaluates patients treated for native aortic coarctation, with at least 7 years of follow-up. To assess time-related changes, three time periods were distinguished according to year of primary intervention (era 1, 2 and 3). Operative and long-term follow-up data were collected by patient record reviews.ResultsThe study population consisted of 206 patients (177 surgical and 29 catheter-based interventions), with a median follow-up of 151 months. Anterior approach with simultaneous repair of aortic arch and associated cardiac lesions was more common in the most recent era. Median age at intervention did not change over time. Reintervention was necessary in one third of the cohort with an event-free survival of 74% at 5‑year and 68% at 10-year follow-up. Reintervention rates were significantly higher after catheter-based interventions compared with surgical interventions (hazard ratio [HR] 1.8, 95% confidence interval [CI] 1.04–3.00, p = 0.04) and in patients treated before 3 months of age (HR 2.1, 95% CI 1.27–3.55, p = 0.003). Hypertension was present in one out of five patients.ConclusionNowadays, complex patients with associated cardiac defects and arch hypoplasia are being treated surgically on bypass, whereas catheter-based intervention is introduced for non-complex patients. Reintervention is common and more frequent after catheter-based intervention and in surgery under 3 months of age. One fifth of the 206 patients remained hypertensive.     

Prognosis of new and worsening angina pectoris.

The natural history of new and worsening angina pectoris was studied in 251 men aged under 70 years. Most were ambulant and all were referred by selected general practitioners to a special hospital clinic over two and a half years. Heart attacks developed in 39 patients, nine of whom died. Seventy-two per cent of the attacks occurred within six weeks of the onset or worsening of angina. Of the 212 patients who did not suffer myocardial infarction and who were clinically reviewed six months after their first attendance 66 had been pain free for the previous three months and 14 had experienced only infrequent attacks of angina. Of the 128 men aged under 65 years who were previously in employment 81% had returned to full-time work six months after their first attendance. A discriminant function analysis using many variables was made to develop a predictive index that would allow patients with new or worsening angina who were likely to develop serious cardiac complications to be identified. This did not prove possible, and the only predictive factor of significance was an increased cardiothoracic ratio. The syndrome of new and worsening angina has a low risk of early death, and many patients are symptom free six months later. In general, emergency coronary arteriography and surgery is not indicated.     

Clinical and Angiographic Outcomes after Intracoronary Bare-Metal Stenting

Background

Data from a large patient population regarding very long-term outcomes after BMS implantation are inadequate. This study aimed to evaluate the very long-term (8–17 years) clinical and long-term (3–5 years) angiographic outcomes after intracoronary bare-metal stenting (BMS).

Methods and Results

From the Cardiovascular Atherosclerosis and Percutaneous TrAnsluminal INterventions (CAPTAIN) registry, a total of 2391 patients with 2966 lesions treated with 3190 BMSs between November 1995 and May 2004 were evaluated. In total, 1898 patients with 2364 lesions, and 699 patients with 861 lesions underwent 6-month and 3- to 5- year angiographic follow-up, respectively. During a mean follow-up period of 149±51 months, 18.6% of the patients died (including 10.8% due to cardiac death), 6.1% developed reinfarction, 16.2% had target lesion revascularization (including 81% of the patients within the first year), 14.5% underwent new lesion stenting (including 72% of the patients after 3 years), 2.4% underwent coronary bypass surgery, and 1.6% had definite stent thrombosis. The overall cardiovascular event-free survival rate was 58.5%. The 6-month angiographic study indicated a 20% restenosis rate. The minimal luminal diameter increased from 0.65±0.44 mm to 3.02±0.46 mm immediately after stenting, decreased to 2.06±0.77 mm at the 6-month follow-up, and increased to 2.27±0.68 mm at the 3- to 5-year follow-up.

Conclusions

This study provides clinical and angiographic results from a large population of patients who underwent BMS implantations after a long-term follow-up period (149±51 months). The progression of coronary atherosclerosis developed over time, and presented with new lesion required stent implantation. The follow-up angiographic findings reconfirmed the late and sustained improvement in luminal diameter between 6 months and 3–5 years.     

Nursing role to improve care to infarct patients and patients undergoing heart surgery: 10?years’ experience

Background

The nurse practitioner may be the ideal healthcare worker to create a new environment and may facilitate in the process of expediting discharge and improving patient safety. They can play an intermediary role between the consultants, nurses and patients, thereby combining the aspects of care (nursing) and cure (physicians).

Method

We describe the contribution and role of the nurse practitioner in a teaching hospital and provide an overview of the changes in care and cure that were facilitated by two nurse practitioners in the treatment of cardiac surgery patients or non-complicated acute coronary syndrome patients.

Results

The nurse-led clinic for postoperative patients has registered 1967 patients in the past 10 years. These patients were transferred at a mean of 5.5 days after their bypass operation. All patients had an uneventful clinical course in our hospital and were discharged alive. The period between discharge and outpatient clinic visit could be set at 4 weeks.The post-acute coronary syndrome (ACS) group included 1236 patients. Mortality in this patient cohort was 4% while 0.4% of these patients experienced a re-myocardial infarction. Additional surgery was needed in only 2% of these stable post-infarction patients. The mean length of stay was 5.9 ± 14.5 days.

Conclusion

This observational study confirms that a nurse-led postoperative care unit and post-ACS care unit is feasible and effective for the treatment of patients returning from cardiac surgery or transferred after uncomplicated ACS to a general cardiology ward.     

Renal replacement treatment for diabetic patients in Newcastle upon Tyne and the Northern region, 1964-88.

OBJECTIVES--To review the experience of renal replacement treatment in diabetic patients treated in Newcastle upon Tyne and the Northern region from 1964 to 1988, and to compare the morbidity and mortality of diabetic patients treated with dialysis or transplantation with those of matched controls of non-diabetic patients. DESIGN--Retrospective study of clinical case notes. SETTING--Renal units of the Northern region, particularly that in Newcastle upon Tyne. PATIENTS--All 65 diabetic patients treated by renal replacement treatment in Newcastle upon Tyne from 1964 to 1987; 42 diabetic patients were matched with 42 non-diabetic patients according to age, sex, year of starting treatment, and type of treatment (dialysis or transplantation). MAIN OUTCOME MEASURES--Sex, age, renal biopsy findings, blood pressure, history of diabetic treatment, and plasma creatinine concentration at the start of renal replacement treatment. History of renal replacement treatments, suitability for transplantation, history of transplantation, cumulative survival, and cause of death during follow up. Survival of technique, cumulative survival of the first peritoneal catheter and history of peritonitis in patients treated with continuous ambulatory peritoneal dialysis; source of graft, histocompatibility antigens, duration of associated stay in hospital, and graft survival in patients receiving renal or pancreatic transplant. RESULTS--1259 Patients with chronic renal failure were accepted for renal replacement treatment in Newcastle upon Tyne, of whom 65 (5%) had diabetes. The first was accepted in 1974, and between 1974 and 1980 another 15 were treated (mean age 42 years; 4% of new patients). From 1981 to 1987, 49 diabetic patients (mean age 44; 9% of new patients) were treated. Fifty patients (77%) had insulin dependent diabetes and the remaining 15 (23%) non-insulin dependent diabetes. On average, the patients were aged 25 (range 5-57) when diabetes was first diagnosed and 44 (range 24-70) at the start of renal replacement treatment. The mean age at the start of treatment was 40 for patients with non-insulin dependent diabetes and 58 for patients with non-insulin dependent diabetes. Transplantation was performed in 33 of the diabetic patients, whose mean age was lower than that of those who did not receive a transplant (41 v 48 respectively, p less than 0.05). Comparison between the 42 diabetic patients and matched controls showed that the overall survival at five years was 46% and 77% respectively. The three year survival of the diabetic patients who did not receive a transplant was poor (41% v 79% respectively). Of patients transplanted, survival at five years was 73% in the diabetic patients and 90% in the controls. However, there was no significant difference in the five year graft survival (64% v 46% respectively). CONCLUSIONS--Diabetes adversely affects morbidity and mortality in patients having renal replacement treatment, but renal transplantation seems to be the best option for treating diabetic patients with end stage renal failure.     

Panniculectomy in preparation for renal transplantation: a new indication for an old procedure to reduce renal transplantation-associated wound complications

End-stage renal disease patients who have lost a significant amount of weight are increasingly being evaluated for kidney transplantation. An abdominal panniculus, almost uniformly observed, creates an area predisposed to wound complications. Consequently, a panniculus may limit a patient's candidacy for transplantation. The authors describe their preliminary experience utilizing panniculectomy as a prophylactic procedure to reduce wound complications following kidney transplantation in patients whose panniculus would exclude them from renal transplantion. A single-institution chart review was conducted of nine patients with end-stage renal disease who underwent a panniculectomy in preparation for transplantation. Clinical outcomes and complications were reviewed. The nine patients included three men and six women with a mean age of 54.5 years and a mean body mass index of 28.3 kg/m. Four patients had diabetes. All patients underwent an uncomplicated panniculectomy, with a mean resected weight of 3.0 kg, and a mean length of hospital stay of 1.75 days. No one required blood transfusions. All patients were followed postoperatively for 3 months. Complications included an abscess and a skin dehiscence treated with local wound care. After recovery, patients were referred to the transplant center for re-evaluation for kidney transplantation. Thus far, four of these nine patients have undergone transplantation. This case series suggests that panniculectomy can be performed safely in patients with end-stage renal disease. Furthermore, panniculectomy gives these otherwise unsuitable kidney transplant candidates access to a life-saving operation.
