Prospective validation of a simple laboratory score to predict outcome after orthotopic liver transplantation

Objective

To establish a score to predict 30-day mortality and graft loss retrospectively and to validate the score prospectively.

Patients and Methods

Retrospectively in 296 liver transplant recipients, a score was developed that included the peak aspartate aminotransferase concentration within the first week and γ-glutamyltransferase and bilirubin concentrations at day 7 to predict graft loss or patient death within 30 days. The score was then prospectively validated in 86 patients undergoing liver transplantation.

Results

From the retrospective training cohort, cut-off values for prediction of adverse outcomes were determined using receiver operating characteristic curve analysis for peak aspartate aminotransferase (>1870 IU/mL), γ-glutamyltransferase (<214 IU/mL), and bilirubin (>5.75 mg/dL). Sensitivity and specificity of the score to predict an end point from the retrospective cohort were excellently reproduced in the prospective cohort. Overall, fulfilment of at least 2 criteria predicted graft loss or death within 30 days with sensitivity of 0.70 and specificity of 0.78. No patients with values that remained below all 3 thresholds experienced graft loss or death within 30 days.

Conclusions

This simple score calculated from standard laboratory values within the first week after liver transplantation enables prediction of graft loss and patient death within 30 days after transplantation. Early identification of patients at risk may help to improve outcomes by observing these patients more closely and allocating resources for them.     

Intestinal transplantation for short bowel syndrome secondary to gastroschisis

Background/Purpose

Gastroschisis is the most frequent cause of pediatric intestinal transplantation. This study reviews our experience of intestinal transplantation secondary to gastroschisis to elucidate those factors affecting the outcome of children with short bowel syndrome.

Methods

A retrospective review was performed for children who underwent intestinal transplantation for gastroschisis at the University of Miami between June 2003 and August 1994.

Results

Thirty-two transplants were performed in 28 children with gastroschisis during the study period. Associated intestinal anomalies were present in 22 infants (atresia [n = 14], volvulus [n = 3], and/or ischemia [n = 16]). Spontaneous prenatal closure of gastroschisis, a rare anomaly associated with bowel atresia and ischemia because of a very small abdominal defect, was seen in 9 patients. Most of the patients had a complicated course and required multiple abdominal surgeries before transplant. Fifteen (53.6%) patients are currently alive at a median follow-up of 23.5 months. Short-term survival rate has significantly improved in recent years.

Conclusions

Patients with complex gastroschisis and intestinal anomalies have a significant risk for progression to short bowel syndrome. Intestinal transplantation can be a lifesaving option and provides a satisfactory outcome for children with short bowel syndrome secondary to gastroschisis.     

Rectal cancer patients benefit from implementation of a dedicated colorectal cancer center in a Veterans affairs medical center

Background

A dedicated colorectal cancer (CRC) center was created in a Veterans Affairs Medical Center with the intent of improving quality of patient care and multidisciplinary cooperation.

Methods

Retrospective and prospective databases before and after creation of the CRC center, respectively, were created. Patients entered in each database included those requiring surgical intervention for CRC treatment. Statistical analyses included Fisher's exact, chi-square, and unpaired Student t tests as well as analysis of variance.

Results

The overall quality of care of CRC patients has improved as evidenced by a larger percentage of complete, margin-negative resections (P <.05) as well as an increase in the number of lymph nodes excised at surgery (P <.0001). Furthermore, a multidisciplinary approach is clearly beneficial as evidenced by the increased number of CRC patients receiving appropriate multidisciplinary therapy (P <.0001).

Conclusions

A dedicated CRC center has significantly improved quality of care for CRC patients.     

Currarino syndrome: proposal of a diagnostic and therapeutic protocol

Background/purpose

The Currarino syndrome (CS) is a peculiar form of caudal regression syndrome (CRS) characterized by the association of hemisacrum, anorectal malformation (ARM), and presacral mass. The authors analyzed retrospectively their series, and they propose a multidisciplinary diagnostic and therapuetic protocol that until now has not been introduced.

Methods

A series of 6 patients with CS is presented. Five of them were treated initially in other centers. None of them had an early diagnosis. All presented associated anomalies; in 50%, Hirschsprung’s disease (HD) and other dysganglionoses were present. One patient died of a presacral ectopic nephroblastoma.

Results

Depending on the expressivity, 3 types of CS can be identified, complete, mild, and minimal. Dysganglionoses and HD can be considered part of CS. A multidisciplinary diagnostic and therapeutic protocol is presented. Main points are sacrum x-Ray, molecular genetic diagnosis, radiologic evaluation of every member of CS families, magnetic resonance (MR) evaluation of patient spine and pelvis, suction rectal biopsies, and search for associated anomalies.

Conclusions

This protocol could give a valid contribution to the treatment of CS, allowing an early diagnosis and proposing a rational timing of multidisciplinary surgical procedures. Early diagnosis and treatment are essential to avoid morbidity and mortality from an undiagnosed presacral mass.     

Ventricular assist system applications in end-stage heart failure

Background

Mechanical circulatory support has an important role in the surgical therapy for heart failure. Patients deteriorating on transplantation waiting lists or those unsuitable for transplantation have been treated with ventricular assist devices. In this report, we have presented application of ventricular assist systems for patients with end-stage heart failure.

Methods

Between April 2007 and September 2010, we treated 37 patients with end-stage heart failure with mechanical circulatory support, including 5 children younger than 16 years of age. Three patients were females, and the overall mean age was 40 ± 18 years (range, 1.5-67). In 29 patients we implanted paracorporeal pneumatic ventricular assist devices. Axial flow pumps were chosen to support the left ventricle in 8 patients. Biventricular support was applied in 9 patients because of their poor preoperative clinical conditions and advanced evidence of right ventricular failure.

Results

Heart transplantation was performed in 16 patients (43%). One subject, who was managed with a left ventricular assist device implantation and coronary bypass grafting, was weaned from the system because of recovery of ventricular functions. Eleven patients (30%) are still on pump support. Nine patients (24%) died during mechanical circulatory support. The most prevalent cause of mortality was multiorgan failure (n = 5; 13.5%). Cerebrovascular hemorrhage was the cause of death in 2 patients. One patient died due to acute lung injury, and an other due to malignant melanoma.

Conclusion

Use of a ventricular assist device as a bridge-to-transplantation or as destination therapy can be performed with acceptable mortality. It may be the most promising option for patients with end-stage heart failure. Development of device technology, advanced monitoring of anticoagulation and anti-aggregation therapy, and greater clinical experience may yield better results.     

Basiliximab for the treatment of steroid-refractory acute graft-versus-host disease after unmanipulated HLA-mismatched/haploidentical hematopoietic stem cell transplantation

Background

Anti-CD₂₅ monoclonal antibodies (Mabs) have been evaluated for the treatment of steroid-refractory acute graft-versus-host disease (GVHD) in patients undergoing hematopoietic stem cell transplantation (HSCT) mainly with matched donors for years, but there is little attention concerning patients with unmanipulated human leukocyte antigen (HLA)-mismatched/haploidentical transplantations. We investigated the efficacy and safety of the chimeric Mab, basiliximab, to treat steroid-refractory acute GVHD after unmanipulated mismatched/haploidentical HSCT.

Methods

Fifty-three patients who developed steroid-refractory acute GVHD between July 2005 and July 2009 were treated at our institute with basiliximab. No prisoners were used in this study.

Results

Forty-six among 53 patients responded, including 37 complete remissions at a median response of 6 days from Mab initiation. There were 29 episodes of viral reactivations, 25 bacterial infections, and 11 probable fungal infections. Thirty-four out of 49 patients who could be evaluated developed chronic GVHD. Twenty-eight of 53 subjects (52.8%) were alive at a median follow-up of 16 months (range, 2-57) posttransplantation. The Kaplan-Meier probability of a 3-year event-free survival was 47.7%. The causes of death were infection alone (n = 15), progressive GVHD with infection (n = 3), relapse (n = 3), and other etiologies (n = 4).

Conclusion

These data suggested that basiliximab was effective to treat steroid-refractory acute GVHD after unmanipulated HLA-mismatched/haploidentical stem cell transplantation.     

Esophageal foreign bodies in the pediatric population: our first 500 cases

Background

Children with esophageal foreign bodies are frequently seen by pediatric surgeons. Choking and dysphagia are common presentations; however, esophageal perforation has been reported. Historically, rigid esophagoscopy with extraction of the foreign body has been the recommended treatment. Alternatively, Foley balloon extraction is a safe and effective approach.

Methods

Over a 16-year period, 555 children presented with an esophageal foreign body. Retrospective analysis of the medical record was undertaken. Statistics were by univariate analysis.

Results

Two hundred ninety-eight boys and 257 girls presented with a mean age of 3.24 years. Dysphagia (37%) and drooling (31%) were the most common symptoms. Foreign bodies were lodged in the superior esophagus in 73%, and 88% of the objects were coins. Balloon extraction with fluoroscopy was performed in 468 children. Eighty percent of the objects were successfully removed with a mean fluoroscopy time of 2.2 min, and 8% were advanced into the stomach. The overall success rate was 88%, with failures necessitating rigid esophagoscopy under general anesthesia. Children younger than 1 year were the most likely to fail (25% failure rate). Airway aspiration never occurred. Significant savings in patient charges were observed with this approach.

Conclusions

Balloon extraction of pediatric esophageal foreign bodies is a safe and cost-effective procedure. This technique is applicable for infants, children, and adolescents. Experienced practitioners should be able to achieve greater than 80% success rate.     

A National Program Toward Improving Renal Health: Advancing Organ Donation Awareness

Background

Despite the national advocacy campaign for kidney transplantation from deceased donors in the Philippines 96% of kidneys transplanted into 721 kidney transplants from 1999 to 2001 came from living donors. A national survey on the knowledge, attitudes and perceptions of Filipinos on organ donation in 2001 showed factors that disadvantaged deceased organ donation to be poor understanding of “brain death,” religion, and fear of the operation. These concerns were addressed and another survey was conducted in 2005.

Objectives

To compare knowledge, attitudes, and perceptions of Filipinos on organ donation between 2001 and 2005, and compare the number of kidney transplants from deceased donors between 2001 until 2008.

Methods

Two surveys in 15 regions of the Philippines were conducted using multistage sampling. Using a structured questionnaire there were 2000 respondents in 2001, and 2140 in 2005. Analysis was performed using chi-square analysis.

Results

The majority of respondents knew about kidney donation. Between 2001 and 2005, there was increased awareness that transplants came from both living and deceased donors (37% to 41%) and a decline in those believing transplants came only from deceased donors (14% to 9%). Willingness to become a living (59% to 87%) or a deceased donor (35% to 49%) increased. The increase in transplantation from deceased donors from an average of 10 per year from 1999 to 2001 to 31 per year from 2006 to 2008.

Conclusion

Increased awareness about kidney donation among Filipinos, improved consent to become an organ donor, and an increase in kidney transplantation from deceased donors occurred from 2001 to 2008.     

Association between urothelial carcinoma after renal transplantation and infection by human papillomavirus types 16 and 18

Objective

To explore the association between urothelial carcinoma following renal transplantation and infection by human papillomavirus (HPV) types 16 and 18.

Materials and Methods

Of 3780 patients who underwent renal transplantation, we identified 90 cases of urothelial carcinoma. Tumor tissues collected from the 90 renal transplant recipients were compared with those from 30 nontransplanted patients with bladder cancer (control group) for HPV types 16 and 18 using polymerase chain reactions.

Results

Seven transplanted patients were HPV positive: HPV-16 was detected in 3 patients with bladder cancer (3/90; 3.3%), and HPV-18 in 2 patients with bilateral pelvic ureteral carcinoma (2/90; 2.2%), and 2 patients with bladder cancer (2/90; 2.2%). Only 2 cases from the control group were HPV positive (both HPV-18; 2/30; 5%). The difference between the RTR and control groups was not significant (P > .05).

Conclusion

Malignant tumors in the urinary system following renal transplantation did not seems to be associated with infection by HPV-16 or -18.     

Outcome of antenatally diagnosed sacrococcygeal teratomas: single-center experience (1993-2004)

Aims

Sacrococcygeal teratomas (SCTs) are the commonest neonatal tumors with an incidence of approximately 1:30,000. There are few large single-center series and even fewer describing both their antenatal and postnatal course. We report the outcome of all fetuses investigated at a tertiary fetal medicine center with this diagnosis.

Method

Demographic details were obtained from a prospectively maintained database. Patient records were examined for additional data including antenatal and postnatal interventions. Data were described as median (range).

Results

Forty-one SCTs were diagnosed antenatally during the period 1993 to 2004. Twelve were excluded from subsequent analysis (single antenatal visit or attending for second opinion [n = 6] and termination of pregnancy [n = 6]). Twelve underwent fetal intervention (laser vessel ablation [n = 4], alcohol sclerosis [n = 3], cyst drainage [n = 2], amniodrainage [n = 2], vesicoamniotic shunt [n = 1]) for fetal hydrops and polyhydramnios to aid in delivery and to prevent obstructive uropathy developing in the fetus. Of these, 3 died in utero and 9 survived to be born (median gestational age, 33 weeks [27-37 weeks]). A further 3 died in the neonatal period. There are 6 long-term survivors (50%) from this group. Seventeen infants, without intervention, were born at median gestational age 38 weeks (26-40 weeks). One infant with severe cardiac anomalies died on the day of birth. All surviving infants had definitive excisional surgery at a median of 2 days (1-16 days). Current median follow-up of survivors is 39 months (8-86 months). There have been no recurrences. One child has mild constipation, and 3 are awaiting cosmetic revision of their scars.

Conclusions

The overall survival of antenatally diagnosed SCT is approximately 77%, with the development of hydrops and others requiring in utero intervention carrying a poor prognosis. Otherwise, the outcome after surgical excision is excellent.     

Complete reversal of the nephrotic syndrome after preemptive pancreas-kidney transplantation: a case report

Background

Nephrotic syndrome due to diabetic nephropathy is presently considered an indication for pancreas-kidney transplantation even in the absence of severe renal failure. Reversal of the nephrotic syndrome has been reported, but the mechanisms of this effect are unclear.

Aim

To describe the renal morphofunctional pattern and the pattern of proteinuria before and after preemptive pancreas-kidney transplantation.

Methods

Methods included quantitative and qualitative assessment of proteinuria as well as renal ultrasound and scintiscan.

Case report

A 42-year-old woman with type 1 diabetes since age 24 had widespread end-organ damage. Renal biopsy (2001) showed a mainly nodular pattern of diabetic nephropathy. Following referral (1999), her serum creatinine ranged from 1.6 to 2.2 mg/dL, with nephrotic range proteinuria (glomerular nonselective, tubular complete). Renal scintiscan revealed bilateral, symmetric, well-perfused kidneys. The functional data before pancreas-kidney graft (February 2003) were: serum creatinine 1.6 mg/dL, creatinine clearance 58 mL/min, serum albumin 2.6 g/dL, proteinuria 9.1 g/d. At hospital discharge (March 2003), the creatinine was 1.2 mg/dL, the creatinine clearance 97 mL/min, the proteinuria 0.676 g/d. Two months later, the creatinine was 1.2 mg/dL and proteinuria 0.421 g/d. A renal scintiscan demonstrated the functional prevalence of the grafted kidney (77% of total function), with vital, almost completely excluded native kidneys (functional contribution, 11.5% each). Proteinuria, ranging from 0.3 to 0.6 g/d, showed a physiological pattern.

Conclusions

Functional exclusion of the native kidneys by renal scintiscan gives morphological support to reversal of the nephrotic syndrome.     

Pregnancy in Renal Transplant Recipients

Objective

Renal transplantation with a well-functioning graft leads to a rapid restoration of endocrine and sexual functions. The aim of this study was to examine our experience with pregnancies among renal transplant patients, particularly with regard to their impact on graft function.

Patients and Methods

We analyzed 10 pregnancies in 7 renal transplant recipients for long-term graft outcomes in terms of clinical and biological data.

Results

The mean patient age was 28.5 ± 4 years. They all received a living donor kidney. The time between transplantation and the onset of pregnancy was 33.4 ± 23.2 months. Regarding the immunosuppressive therapy, all patients received steroids and cyclosporine; 4 patients received in addition azathioprine and 2 received mycophenolate mofetil that was changed at 1 month before conception to azathioprine. There was no significant difference between the serum creatinine before and during pregnancy. We did not observe any acute rejection episode. Pregnancy complications were preclampsia in 1 case, hypertension in 1 case, urinary tract infection in 2 cases, and anemia in 80% of patients during the third trimester. Premature rupture of membranes occurred in 1 case and preterm delivery in 2 cases. Two cases of neonatal death were registered. Cesarean section was performed in 50% of cases. The follow-up revealed 2 cases of chronic rejection.

Conclusion

A multidisciplinary approach is necessary for pregnancy which generally occurs at 2 years after kidney transplantation.     

The spectrum of surgical jaundice in infancy

Background

Conjugated jaundice arising during infancy may be caused by a number of different surgical conditions. The aim of this study was to compare clinical features, management, and outcome of all types of surgical jaundice presenting in the first year of life.

Methods

A retrospective review was conducted of all infants born in the United Kingdom with jaundice caused by a surgical cause referred to the authors’ institution from January 1992 to December 1999.

Results

There were 171 infants who could be separated into 3 specific groups: biliary atresia (BA, n = 137), inspissated bile syndrome (IBS; n = 14), and choledochal malformation (CM; n = 12) together with a group containing various miscellaneous conditions (n = 8). Infants with BA had higher bilirubin (P < .01) and aspartate aminotransferase levels (P < .001) and came to surgery earlier (P < .01) than infants with either IBS or CM. Infants with IBS and CM were more likely to be premature and have other malformations, respectively. Ultrasound scan was the principal investigation in the differentiation of BA from other causes of jaundice. Accurate prelaparotomy diagnosis was made by percutaneous liver biopsy in 87% of cases later shown to be BA. Currently, 88 (64%) of children with BA are alive with their native liver postportoenterostomy, 4 have died, and 45 have undergone liver transplantation (with 1 death postoperatively). A policy of primary portoenterostomy for BA followed by transplantation, if necessary, resulted in a survival rate of over 95%. All children in the other diagnostic groups are alive and anicteric after appropriate surgical intervention.

Conclusions

Approximately 80% of infants presenting with surgical jaundice have biliary atresia, whereas those with inspissated bile syndrome and choledochal malformations make up most of the remainder. Mortality in this age-group is confined to infants with BA, but even on these infants an overall survival rate of greater than 95% is currently expected.     

Dietary fat for infants with enterostomies

Background/Purpose

Infants with enterostomies frequently have signs of short bowel syndrome. Our goal was to assess the effect of dietary lipids on ostomy output and weight gain in infants with enterostomies.

Methods

We reviewed the medical records of 10 neonates with necrotizing enterocolitis or isolated intestinal perforations requiring temporary enterostomies. Infants had high stoma outputs and poor weight gain. All infants received a commercially available soluble dietary fat supplement added to their enteral feedings. Ostomy output as a percentage of enteral intake and daily weight gain were compared over 5-day intervals before and after adding the dietary fat.

Results

We observed a decrease in ostomy output after the addition of dietary lipids to enteral feedings, from an average of 29.3% to 19.8% of dietary intake, a relative decrease of 32% (P < .05). Daily weight gain increased from an average of 7.7 g/d to 26.8 g/d (P < .01) after treatment initiation. Infants with the greatest ostomy output (>20% of dietary intake) benefited the most by adding the dietary fat.

Conclusions

Dietary lipids appear to decrease ostomy output and improve weight gain in infants with enterostomies and short bowel syndrome. The use of dietary lipids may be helpful in infants with enterostomies to limit the morbidity of this condition.     

Cáncer gástrico por laparoscopia: análisis de los datos del Registro Nacional de Cirugía Gástrica por Laparoscopia

Objective

To study the data from the Laparoscopic Gastric Surgery Spanish National Register of laparoscopic Gastric Surgery and to analyse the type of surgery, the conversion to laparotomy, postoperative complications and mortality.

Patients and Method

From March 2005 to July 2008, details of 302 laparoscopic gastric surgical interventions were sent to the Association of Spanish Surgeons web-site. Details of surgical technique, reconversion, clinical and pathological data, morbidity and mortality were collected and analysed.

Results

A total of 245 patients had gastric adenocarcinoma, 35 of them stromal tumours and 22 other gastric pathologies. In gastric adenocarcinoma patients, resection was performed in 232 cases (95%). The most frequent histology was intestinal, mainly located in the distal third of the stomach, with 34% of the tumours being locally advanced. D2 lymphadenectomy was performed in 117 cases, D1 in 105, and D0 in 6. Reconversion was needed in 21 cases (9%), with technical difficulty being the most frequent cause . Postoperative complications were reported in 72 patients (31%), with anastomotic leak being one of the most significant. Postoperative mortality was 6%, with sepsis due to anastomotic leak and cardiac or respiratory complications the most frequent causes. The mean hospital stay of patients without complications was 9.2±3 days.

Conclusions

Laparoscopic gastrectomy for gastric cancer is a feasible but technically demanding procedure. Potential benefits of minimal invasive surgery can be reduced due to a high rate of postoperative complications.     

Ventricular assist device application as a bridge to pediatric heart transplantation: a single center's experience

Objectives

There are limited options for mechanical circulatory support to treat end-stage heart failure in pediatric patients. Although extracorporeal membrane oxygenation is commonly used in infants and children, ventricular assist devices (VAD) provide a longer duration of support with fewer complications before recovery or as a bridge to heart transplantation (HTx), as described herein.

Methods

This retrospective chart review of eight patients transplanted from April 2008 to December 2011, after left ventricular assist device (LVAD) implantation due to end-stage heart failure. Their mean age was 12 years (9-15 y) and mean body weight, 48 kg (20-78). All were New York Heart Association functional class IV with mean left ventricular ejection fractions less than 15%.

Results

The six patients (75%) received HTx after a mean LVAD support duration of 43.2 days; 2 (25%) died before a suitable heart became available. Their mean duration of LVAD support was 30 days. There were 4 (50%) who experienced clinically evident thromboembolic events: 3 (37.5%) cerebrovascular with 1 mortality and 1 (12.5%) as acute limb ischemia. Transient hemodialysis was performed in 4 (50%). Bloodstream infection identified in 6 (75%) was controlled with intravenous antibiotics. Driveline infection identified in 4 (50%) was treated successfully with local wound dressing changes and intravenous antibiotics. One 9-year-old boy died of rejection at 16 months after transplantation.

Conclusions

Because of the organ shortage, pediatric patients have a low chance to undergo HTx. VAD provides long-term support for children with end-stage heart failure before a suitable heart becomes available. A thromboembolic event remains a major complication influencing their survival.     

Congenital biliary atresia: liver injury begins at birth

Background

The timing of onset of liver injury in biliary atresia (BA) is not known, although in approximately 10% of cases, biliary pathologic condition associated with the biliary atresia splenic malformation syndrome must begin well before birth.

Methods

The study involved retrospective case-note review for infants with definite BA who underwent laparotomy within first week of life.

Results

Three infants were identified who had occlusive BA evident on the first day of life. In all cases, their liver was grossly normal, and histologic changes were trivial.

Conclusion

This suggests that the detrimental cholestatic liver injury, later characteristic of BA, only begins from the time of birth despite a prenatal occlusive biliary pathology. It may be that tissue injury only occurs with the onset of the perinatal bile surge initiating periductal bile leakage and the triggering of an inflammatory and ultimately fibrotic response.     

Establishment of an Ex Vivo Lung Perfusion Model Using Non-Heart-Beating Large Pigs

Background

Functional evaluation of potentially damaged lungs donated after cardiac death is crucial for widespread clinical transplantation. To date, the mean weight of animals used in studies of ex vivo lung perfusion (EVLP) has been 60 kg; however, in the clinical setting, donor weight may be greater.

Objective

To investigate EVLP using lungs from large pigs (mean weight, 115 kg) to simulate human adult lungs donated after cardiac death.

Materials and Methods

Five heart-lung blocks were obtained at 20 minutes after death at the slaughterhouse. The lungs were flushed and preserved on ice for 6 hours before being connected to an ex vivo lung circuit, and were perfused for at least 2 hours.

Results

In all cases, perfusion was sustained for at least 2 hours. Mean (SEM) final flow rate was 4.9 (0.1) L/min, pulmonary artery pressure was 14.8 (1.7) mm Hg, and oxygen tension/fraction of inspired oxygen was 518.0 (18.0) mm Hg. The shunt fraction was 20.5% (4.0%). Histologic analysis demonstrated no significant pulmonary edema at the end of perfusion.

Conclusion

We successfully completed EVLP using lungs from large pigs.     

Importance of Introduction of a Psychological Care Unit in a Liver Transplantation Unit

Background

Psychological changes in terminally ill patients with liver disease are underestimated. Therefore, a psychological care unit was introduced in the liver transplantation unit in a transplantation hospital in Spain.

Objectives

To describe the establishment of the psychological care unit in a liver transplantation unit and to review its operation, and to evaluate and diagnose psychological changes in patients on the waiting list for liver transplantation.

Materials and Methods

Variables evaluated included consultations, interviews, level of care provided, appointments postponed, difficulties, and cost-effectiveness.Psychopathologic symptoms were evaluated using the Symptom Assessment-45 questionnaire (Derogatis, 1975), examining 9 psychopathologic dimensions.

Results

Thirty-eight patients were given an appointment, and 28 were interviewed. Twelve postponed the appointment. The level of support provided to patients on the waiting list was 70%. The hospital structure was used to develop the care unit, which is why it was only necessary to employ 1 professional psychologist. Of patients assessed, 54% exhibited relevant clinical symptoms of depression, and 47 demonstrated anxiety. Patients with symptoms of depression reported “loss of interest”; those with anxiety reported feeling “worried and tense.” Of these patients, an increased presence of symptoms was associated with various emotional problems such as hostility (33%), somatization (60%), obsession/compulsion (73%), interpersonal sensitivity (40%), phobic anxiety (20%), paranoid ideation (20%), and psychosis (6%).

Conclusions

Patients on the waiting list for liver transplantation demonstrate increased clinical symptoms of depression and anxiety. Therefore, it is of great importance to introduce a psychological care unit to detect and treat these conditions. Introduction of the liver transplant unit program has improved multidisciplinary care and is cost-effective.     

Serological Profile of Pretransplantation Liver Patients

Introduction

A liver transplantation is the first choice of treatment for patients with hepatic insufficiency due to chronic diseases. Infections in the postoperative period represent one of the main causes of mortality in these cases. However, few articles have evaluated the predominance of certain infectious diseases and their influence on postoperative mortality.

Methods

We retrospectively evaluated the medical records of 236 patients who underwent liver transplantation from January 1997 to January 2007. In these records we checked the serological profiles for these diseases: toxoplasmosis, syphilis, human T lymphotropic virus (HTLV) I and II infection, Chagas disease, hepatitis A, hepatitis B, hepatitis C, paracoccidioidomycosis, tuberculosis, acquired immunodeficiency syndrome, cytomegalovirus (CMV), and mononucleosis (Epstein-Barr virus [EBV]). The statistical analysis was performed by table frequencies.

Results

CMV showed positivity (CMV-IgG) in 94.7% of patients, 95.8% for EBV, 33.3% for toxoplasmosis, 47.9% for hepatitis C, and 5% for hepatitis B.

Conclusion

Our analysis showed the importance of serological investigations and diagnostic examinations before the transplantation procedure, seeking to minimize possible reactivation of the disease after the use of immunosuppression drugs, particularly in the first 6 months after transplantation, or even to avoid a primary infection.
