RESUMEN

OBJECTIVE/BACKGROUND: Endovascular repair (EVAR) of mycotic aortic aneurysm (MAA) has become an alternative treatment for high risk patients. The aim of this study was to evaluate long-term survival and outcomes. METHODS: Retrospective analysis of 40 consecutive patients with MAAs undergoing EVAR and subsequent intravenous antibiotic treatment between September 2009 and April 2015. Follow-up was truncated on 30 April 2015. Uni- and multivariate logistic regression were used to assess risk factors of adverse outcomes. Cumulative survival was calculated using the Kaplan-Meier method. RESULTS: Median age at repair was 73 years (range 48-88 years) and 31 (77%) were men. Eleven (27%) patients were infected with Salmonella, 12 (30%) with non-Salmonella species, and 17 (42%) had negative cultures. Anatomical locations included the aortic arch/thoracic area in 10 (25%), the paravisceral area in seven (17%), and the infrarenal area in 23 (57%). Ten (25%) patients presented with aneurysm rupture and underwent emergency repair. Median follow-up was 25 months (range 1-69 months). Cumulative 1 and 5 year survival rates were 71% and 53%, respectively. Persistent or recurrent infection occurred in 20% (n = 8). Patients with persistent infection were treated with long-term medical therapy, but all died (75%; n = 6) within 6 months of repair. No survival difference was found between patients with or without Salmonella infections. However, there was a trend toward better survival in culture negative patients. CONCLUSION: EVAR of MAA is an acceptable alternative treatment of MAA. However, persistent infection after endovascular treatment does occur and is often fatal without surgical treatment.

RESUMEN

OBJECTIVE: Tacrolimus, a potent calcineurin inhibitor, is a widely used immunosuppressant. This study sought to determine whether conversion from cyclosporine to tacrolimus afforded benefits on biochemical profiles and graft function among Chinese heart transplantation recipients. METHODS: Forty-nine patients (44 men and 5 women) among 252 heart transplantations performed from 1995 to 2005 were converted from cyclosporine to tacrolimus due to rejection (69%) or to cyclosporine intolerance (31%). The median age of these recipients at transplantation was 46.4 years (range, 5 months to 68 years). Their median body weight was 60 kg (range, 4-84 kg). The allograft median ischemic time was 145 minutes (range, 52-300 minutes). We compared the biochemical markers, rejection episodes and allograft function. RESULTS: The mean duration from heart transplantation to conversion was 419 days. After conversion, the serum bilirubin and alanine transaminase levels were significantly improved at 1 year. The lipid profiles, including triglycerides, total cholesterol, and low-density lipoprotein were nonsignificantly changed. The rejection episodes significantly decreased from 1.53 to 0.15 per patient per year (P < .001). The left ventricular ejection fraction significantly improved from 54.3 +/- 17.9% to 63.2 +/- 10.9% (P < .01). The right atrial pressure significantly decreased from 9.1 +/- 5.8 mmHg to 6.3 +/- 4.3 mm Hg (P < .01). The pulmonary capillary wedge pressure significantly decreased from 15.3 +/- 9.5 mm Hg to 10.8 +/- 5.3 mm Hg (P = .04). CONCLUSION: In heart transplantation, conversion to tacrolimus owing to rejection or cyclosporine intolerance showed better liver profiles with fewer rejection episodes and improved graft function.

RESUMEN

Cryptococcosis is a rare infection with high mortality in patients who have undergone heart transplantation (HT). In this study, we report four cases of the disease selected from our 328 HT cases (1.22%) between 1987 and 2007. The purpose of this study was to review risk factors for cryptococcosis after HT. Three of the four patients were men. The mean time from HT to diagnosis was 8.5 months (range, 3-17 months). Cryptococcosis was subcutaneous in one patient, systemic in one, and meningeal in two. One patient died. The Antifungal regimens included intravenous amphotericin B (amBisone) and oral fluconazole (Diflucan). Patients with diabetes mellitus or renal insufficiency, are hepatitis B carriers, have undergone repeat HT, or are receivings steroid therapy are susceptible to cryptococcosis. The recommend anticryptococcal therapy is amphotericin B, followed by oral fluconazole for at least 6 months. Early diagnosis with aggressive diagnostic techniques and a combination of therapies must be considered to reduce the risk of death in HT recipients with cryptococcosis.

RESUMEN

After clinical heart transplantation (HT), it is crucial to use appropriate immunosuppressive agents to prevent rejection. The use of basiliximab or rabbit anti-thymocyte globulin (RATG) for induction therapy has significantly reduced the incidence of acute rejection episodes after kidney transplantation. In this study we sought to examine the effects of basiliximab after HT. From June 2006 to July 2007, we performed 43 HT including patients 18-65 years old undergoing primary HT who were included in this study of basiliximab induction (20 mg intravenous [iv] on days 0 and 4). Cyclosporine and everolimus were given with basiliximab induction. All others received RATG induction (1.5-2.5 mg/kg iv infusion on days 0, 1, and 2) followed by cyclosporine or tacrolimus combined with mycophenolate mofetil. All patients underwent the same operative procedure, steroid-tapering protocol, and postoperative care with protocol endomyocardial biopsy. Basiliximab was well-tolerated and easy to use. There was only 1 operative mortality; the patient died of sepsis due to Enterobacter cloacae. All others survived the operation and are alive and in good health with a 2-year survival rate of 92.86%. No severe adverse events were noted during the first postoperative month. No acute rejection > or = grade 2R or rejection associated with hemodynamic compromise was noted during the whole course. Basiliximab as induction immunosuppressant was simple, safe, and effective after HT.

RESUMEN

This study retrospectively investigated the outcomes of cardiac transplantation in a single medical center in Taiwan. From February 1997 to December 2005, 214 orthotopic cardiac transplantations were performed in our institution. Cumulative survival rates were compared by gender, waiting status, blood type, ischemia time, donor gender, age, and cause of brain death. The cumulative survival rates were significant different among recipient waiting status (P = .0026), blood type (P = .0376), and donor age > 40 years (P = .0260). The others parameters seem to not be different from the cumulative survival rate. There was a strong association between donors > 40 years old and increased postoperative mortality. The age of a marginal donor seemed to be > 40 years in this study.

RESUMEN

Because of a shortage of deceased donors, more than one-third of patients die during the waiting period for transplantation. This study was conducted to analyze the influence of gender on survival after heart transplantation. We retrospectively reviewed the recipients after primary orthotopic heart transplantation. According to gender, patients were divided into four groups: male donor to male recipient, male donor to female recipient, female donor to male recipient, and female donor to female recipient. Kaplan-Meier survival curves were plotted with log-rank tests. Cox regression analysis with dummy variables were used to examine the effects of donor gender, recipient gender, and donor-recipient gender combinations on survival after heart transplantation. The data did not show any significant effect of donor gender, recipient gender, or donor-recipient gender combinations on patient survival, using the methods of log-rank test and Cox regression with dummy variables. Based on our results, we concluded that gender was not an important factor in organ allocation.

RESUMEN

With improved immunosuppressive regimens, transplantation techniques, and postoperative care, heart transplantation (HTx) has been established as a definite therapy for end-stage heart disease. Because of a donor shortage, we have accepted marginal individuals. In this study, we identified donor-related factors influencing survival after HTx by retrospective analysis of recipient data after primary HTx from February 2002 to December 2006. The Cox regression model was used to examine the effects of the following variables on survival of 112 heart transplant recipients: demographic data of gender, age, body weight, donor-recipient body weight ratio; history of smoking, alcohol drinking, diabetes mellitus, hypertension, hepatitis B surface antigen, anti-hepatitis C virus antibody; donor condication before transplantation including catecholamine doses, hypotension, cardiopulmonary resuscitation, creatine MB isoenzyme of creatine kinase (CK-MB), tropinin I, and cold ischemic time of the allograft. Catecholamines and smoking showed significant influences on HTx survival. In our series, the percentage of donors receiving inotropic support before donation was 88% (n = 99), and the percentage of donors with a history of smoking was 25% (n = 28). There was no influence of donor status of diabetes, hypertension, or hepatitis B or C infection on postoperative survival. Our results showed that inotropic support of and a history of smoking by the donor were significant factors influencing posttransplant survival.

RESUMEN

We describe a case of complex congenital heart disease treated using balloon septostomy, pulmonary artery banding. Blalock-Taussig shunt, and cardiac resynchronization therapy; however, heart failure developed. A bicaval anastomosis was used to relieve superior vena cava (SVC) obstruction despite possible anastomotic stenosis. The postoperative course was uneventful and the patient recovered rapidly. Thus, we recommend bicaval anastomosis using a longer donor SVC concomitantly performed during heart transplantation to relieve both heart failure and SVC obstruction in pediatric patients.

RESUMEN

OBJECTIVE: In this study, we examined whether cyclosporine was effective when combined with everolimus in clinical heart transplantation (HT). PATIENTS AND METHODS: From August 2004 to July 2007, 108 adult patients underwent primary HT. The main exclusion criteria were: donors > 60 years; cold ischemia times > 6 hours; recipients of multiorgan transplantation or a previous transplantation; and panel-reactive antibodies > or = 25%. The cyclosporine plus everolimus regimen (group CE, n = 32) was suggested first; upon refusal or if the recipient or donor was positive for hepatitis B surface antigen or PCR + hepatitis C infection, then patient was randomly assigned to success cyclosporine plus mycophenolate mofetil (MMF; group CM, n = 24) or tacrolimus plus MMF (group TM, n = 25). All patients underwent similar operative procedures and postoperative care with protocol endomyocardial biopsies. RESULTS: No 30-day mortality was noted in any group. The efficacy failure rates were 3%, 25%, and 16% in groups CE, CM, and TM, respectively (P = .04 between groups CE and CM). The 1-year survivals were 96.7% +/- 18.1%, 89.7% +/- 29.8%, and 81.0% +/- 35.5% for groups CE, CM, and TM, respectively (P = .04 between groups CE and TM). The 3-year survival rates were 91.9% +/- 28.3%, 79.8% +/- 46.0%, and 81.0% +/- 35.5% in groups CE, CM, and TM, respectively. CONCLUSIONS: The 3 immunosuppressive regimens offered good efficacy after HT. The cyclosporine plus everolimus regimen showed a significantly better result with less efficacy failure (compared with cyclosporine plus MMF: 3% vs 25%) and better 1-year survival compared with tacrolimus plus MMF: 96.7% vs 81.0%.

RESUMEN

Patients receive methylprednisolone pulse therapy (MPT) when acute cardiac rejection occurs. Although the regimen is generally safe and effective, severe complications occasionally develop. From 1997 to 2007, there were 210 cardiac transplantation procedures performed at our hospital. Among these patients, there were 23 episodes of acute rejection treated with MPT, 10 mg/kg/d. Two patients in our series had cardiac arrest within 36 hours after initiating the therapy. Endomyocardial biopsy specimens showed International Society for Heart Transplantation grade 1B allograft rejection in both cases. Emergent intubation and cardiopulmonary resuscitation were performed. Venoarterial extracorporeal membrane oxygenation (ECMO) was used to rescue the patients. The cardiac function in both patients recovered gradually. Left ventricular ejection fraction increased from 16.2% to 47% in one patient and from 27% to 30% in the other patient. One patient was successfully weaned from ECMO after 2 days of support. The other patient was discharged against medical advice because of hypoxia-related brain death after 3 days. Both patients had a history of tachyarrhythmias before initiation of MPT. Although the relationship between mechanisms of cardiac arrest and MPT is uncertain, the risk of cardiac arrest cannot be overlooked when initiating MPT, especially in patients with a history of tachyarrhythmia. Meanwhile, ECMO can serve as a rescue method if cardiac arrest occurs.

RESUMEN

Mediastinitis is a life-threatening complication among patients undergoing cardiac transplantation. There are conservative and aggressive surgical treatments. From October 1987 to October 2007, we reviewed the clinical records of 315 heart transplantations for those four cases with severe mediastinis needing surgical treatment for demographic data, clinical presentation, treatment, and outcome. Conservative therapy, such as sternal debridement without muscle flap closure and closed local irrigation with drainage, was performed in two cases. The other two patients needed aggressive surgical treatment with muscle flap or omental flap performed. Only one transplant recipient with severe mediastinis had undergone previous sternotomy before cardiac transplantation. The organisms were methicillin-resistant Staphylococcus aureus in three and Aspergillus fumigatus in one case. The one subject who received conservative therapy without a flap died. The other two with muscle flap and omental flap survived. Cardiac recipients survived if there was aggressive surgical treatment for severe mediastinitis. Meanwhile, we recommend prolonged aggressive antibiotic therapy and reduced immunotherapy.

RESUMEN

The incidence of tuberculosis is slightly higher among heart transplantation cases than in the general population in Taiwan. Tuberculosis shows a high mortality rate ranging from 22% to 31% in transplant recipients. From October 1987 to October 2007, we performed 315 heart transplantations. Clinical records were reviewed for demographic data, clinical presentation, treatment, and outcome. Tuberculosis was diagnosed by cultures of any body sample in association with compatible symptoms and signs. Mortality was related to tuberculosis if there was evidence of active tuberculosis at the time of death and no other etiology accounted for death. Ten patients who had received heart transplants were diagnosed as tuberculosis. There were seven pulmonary lesions and seven extrapulmonary lesions. Treatment consisted of isoniazid, rifampin, ethambutol, pyrazinamide, streptomycin, ciprofloxacin, and levofloxacin. Seven patients completed the antituberculosis treatment: the median treatment duration was 1 year. Three patients developed hepatitis. There was no tuberculosis-related mortality. Ten out of a total of 315 patients (3.17%) represented a tuberculosis rate higher than that reported for the general Taiwan population (67/100,000). This high mortality of infection may be completely treated by a combination of at least three drugs except pyrzinamide because of side effects and tolerance.

RESUMEN

We report a heart transplantation in a patient with no heart. A 60-year-old man suffered from severe infective endocarditis, and due to extensive involvement of the myocardium, only minimal myocardium was left after debridement of the necrotic myocardium and aortic annulus. We finally excised the entire heart to eradicate the infection source and employed 2 extracorporeal membrane oxygenations for full life support. The infection was controlled with strong antibiotics. The patient underwent successful heart transplantation 16 days following the excision and the patient fully recovered without any complications.

RESUMEN

OBJECTIVES: An oversized cardiac allograft may have a negative impact on survival outcomes according to previous studies; however, due to the shortage of pediatric donor hearts, the use of oversized cardiac allografts is sometimes inevitable. In this study, we reported the survival outcomes of pediatric patients in relation with the donor-recipient weight ratio. METHODS: Twenty-eight children, aged 3 months to 17 years, with dilated cardiomyopathy underwent primary cardiac transplantation at the National Taiwan University Hospital between 1995 and 2012. We analyzed these patients according to the donor-recipient weight ratio: group 1 (n = 19) with donor-recipient weight ratio <2.5 (median 1.1, interquartile range 1.0-1.6), and group 2 (n = 9) with donor-recipient weight ratio ≥2.5 (median 3.0, inter-quartile range 2.87-3.5). RESULTS: The 30-day survival rate was 100% for both group 1 and group 2 (P = 1). The survival rates for group 1 and group 2 were 95% vs 100% at 1 year, 84% vs 89% at 5 years, and 73% vs 61% at 10 years. The median survival was 14.4 years vs 12.9 years (P = .6313). CONCLUSION: In this cohort, the use of oversized cardiac allograft in pediatric patients for dilated cardiomyopathy did not have a negative effect on short-term and long-term survival.

RESUMEN

Renal function after heart transplantation (HTx) typically follows a biphasic pattern and an initial decay within 1 to 2 years. Trajectory of renal function after HTx is less reported, especially in Asia. The aims of this cohort study were to describe the changes in HTx recipients' serum creatinine and estimated glomerular filtration rate (eGFR) levels 5 years following HTx in Taiwan. METHODS: We retrospectively reviewed 5 years of 440 consecutive adult patients (≥ 18 years) who underwent first HTx from June 1987 to December 2014 at the National Taiwan University Hospital. RESULTS: Among 422 participants, they received induction therapy consisting of intravenous rabbit antithymocyte globulin. Here, we illustrated the trends over the years by dividing the subjects into 2 groups based on their immunosuppressive regimen of transplantation (1987-2002 and 2003-2014) The pretransplantation median serum creatinine concentration level was 1.2 mg/dL, rose to 1.4 mg/dL at 3 months after surgery, and remained steady over 5 years after HTx. Pretransplant median eGFR was 67 mL/min/1.73 m2.The median serum creatinine concentration level and eGFR at baseline were all significantly difference than pretransplantation (P > .05). This result has showed that an initial steep decline within 3 months after transplant remained stable 5 years after HTx. CONCLUSION: As renal function deteriorates after HTx, we observed a steep decline in serum creatinine level and glomerular filtration rate within the 3 months after HTx, followed by a slow rate of deterioration over the following months. We found a time-related progressive deterioration in renal function during the 5 years after HTx.

RESUMEN

OBJECTIVE: This study sought to determine the influence of everolimus on cyclosporine Neoral (CsA) pharmacokinetics over the first 6 months after heart transplantation in Chinese recipients. METHODS: Six de novo cardiac recipients receiving a CsA-everolimus-based immunosuppressive regimen after rabbit antithymoglobulin sequential immuno-induction were compared with six age-matched recipients receiving a CsA-azathioprine-based regimen. We compared CsA 12-hour area-under-curve (AUC) of the first dose (PK-1) and steady state dose (PK-S) at 1 month after transplantation. The CsA trough concentrations (Cmin) were compared over the first 6 months after transplantation. RESULTS: There was no significant difference between the two groups in age, gender, and body weight. With respect to dose-normalized CsA AUC(0-infinity) of PK-1 and dose-normalized CsA AUC(0-12) of PK-S, the difference between the everolimus- and the azathioprine-based regimens was not significant. The dose-normalized CsA trough concentrations (Cmin/dose) were significantly lower in the everolimus-based group than in the azathioprine-based group during the first 5 months after heart transplantation, but the difference was not significant at posttransplantation month 6. CONCLUSIONS: When CsA pharmacokinetic profiles were considered, the CsA dose requirement was not lower in Chinese patients receiving everolimus than that in patients receiving azathioprine. The results differed from reports from Western countries.

RESUMEN

Ventricular assist devices (VAD) have benefitted patients with end-stage heart failure as a bridge to heart transplantation (HTx). We present our experience with HTx after an extracorporeal membrane oxygenation (ECMO) hybrid with various ventricular assist devices (VAD). From May 1996 to December 2003, mechanical circulatory support with a Biopump VAD was performed in eight patients, HeartMate left VAD in eight patients, and Thoratec VAD in eight patients. Before VAD implantation, 19 patients maintained their circulation with ECMO. Half of the 24 patients were implanted with VAD to await a suitable donor for HTx. We observed that half of the patients supported by ECMO hybrid with various VAD awaited a suitable donor for HTx. In our experience, we recommend the application of ECMO for short-term support within 1 week and the Biopump VAD, Thoractec VAD, or HeartMate VAD for medium-term or long-term support as a bridge to HTx.

UNLABELLED: This study determined cyclosporine Neoral (CsA) pharmacokinetics and the accuracy of a limited sampling strategy to predict the 12-hour CsA area-under-the-curve (AUC) to provide a practical method for more accurate therapeutic drug monitor of CsA among de novo Chinese heart transplant recipients treated with an everolimus-CsA immunosuppressive regimen. METHODS: Blood samples were collected at 0, 0.5, 1, 2, 3, 4, 6, 8, 10, and 12 hours after oral administration of CsA in six de novo heart recipients receiving a CsA, everolimus, and methylprenisolone immunosuppressive regimen after rabbit antithymoglobulin sequential immuno-induction. We analyzed the pharmacokinetics of the first dose (PK-1) and steady state dose (PK-2) at 1 month after transplantation. The accuracy of a single-point sampling method to predict the AUC was generated by linear regression analyses. RESULTS: The t(max) and dose-normalized C(max) of PK-1 and PK-2 were similar. The correlations in single-point blood levels of PK-1 to predict the AUC(0-infinity) were much lower than the corresponding sampling times in PK-2. In PK-2 study, C4 had the best correlation (r(2) = 0.913, P = .003) to predict AUC(0-12). In addition, the trough concentrations, C(0) (r(2) = 0.875, P = .006) and C(12) (r(2) = 0.783, P = .02) also showed good correlations. C2 had insufficient correlation to predict AUC(0-infinity) in PK-1 or AUC(0-12) in the PK-2 study. In conclusion, the absorption of CsA was similar during PK-1 and PK-2. At steady dose, C4 had the best single-point correlation to predict AUC(0-12). Trough blood levels may be more practical in clinical use to monitor CsA.

RESUMEN

Simultaneous heart and kidney transplantation (SHKT) is feasible for combined cardiac and renal failure. Herein we reviewed our 10-year experience in SHKT. Six patients underwent SHKT from June 1995 to December 2004. Their ages ranged from 13 to 63 years old with a mean of 45.5 +/- 15.8 years. They were all men except one girl, who was the youngest (aged 13) who suffered from dilated cardiomyopathy with congestive heart failure and chronic renal failure due to systemic lupus erythematosus. Because of aggravating heart failure, she changed from hemodialysis to peritoneal dialysis. Because of intractable heart failure, she underwent SHKT from a 24-year-old female donor. All received hemodialysis before SHKT. The indications for heart transplantation included dilated cardiomyopathy (n = 3), ischemic cardiomyopathy (n = 1), cardiac allograft vasculopathy (n = 1), and cardiac allograft failure (n = 1). The immunosuppressive protocol and rejection surveillance were these employed for heart transplantation. No operative mortality was noted in this study. The 1-year and 5-year survival rates were the same, 83%. The 10-year survival rate was 55%. No cardiac or renal allograft rejection was noted. No renal allograft loss was noted. There were two late mortalities: the one, who underwent redo heart transplantation for coronary artery vasculopathy died of cardiac allograft failure 1 year after SHKT. The other patient died of massive ischemic necrosis of the intestine at 6 years after SHKT. Our experience showed that SHKT had good short- and long-term results without increasing immunosuppressive doses. End-stage failure of either the heart or the kidney did not preclude heart plus kidney transplantation.

RESUMEN

Patients with hepatitis B virus (HBV) infection have a higher morbidity and mortality after heart transplantation (HT). HBV infection is endemic in Taiwan. We studied the effect of lamivudine treatment of HBV infection after HT. From July 1987 to July 2005, 252 patients underwent HT. All recipients and donors underwent routine screening of hepatitis B surface antigen (HBsAg), hepatitis B e antigen, antibody to hepatitis B surface antigen, antibody to hepatitis B core antigen, antibody to hepatitis B e antigen, and an alanine aminotransferase (ALT) level before HT. When ALT was two times greater than the upper limit of normal or serum bilirubin was higher than 3 mg/dL in HBsAg-positive patients, HBV-DNA were checked by a branched DNA assay or polymerase chain reaction. When HVB-DNA was greater than 100,000 copies/mL, lamivudine (100 mg per day) was prescribed indefinitely. There were 14 patients under lamivudine treatment after HT, among whom, none suffered severe adverse reactions from lamivudine. Four patients died: one due to end-stage cirrhosis while awaiting liver transplantation at 14 months after HT. Two died of sudden death at 54 months and 138 months after HT. Another died of diffuse B cell lymphoma at 62 months after HT. All the survivors have normal ALT and undetectable HBV-DNA after lamivudine treatment. But the YMDD mutant was detected in two patients. With successful treatment of HBV infection in HT, it is not necessary to exclude HBV infection patients from HT.
