Immunogenicity of Inactivated SARS-CoV-2 Vaccine (BBIBP-CorV; Sinopharm) and Short-Term Clinical Outcomes in Vaccinated Solid Organ Transplant Recipients: A Prospective Cohort Study.

BackgroundImmunocompromised patients have lower seroconversion rate in response to COVID-19 vaccination. The aim of this study is to evaluate the humoral immune response with short-term clinical outcomes in solid organ transplant recipients vaccinated with SARS-CoV-2 vaccine (BBIBP-CorV; Sinopharm).MethodsThis prospective cohort was conducted from March to December 2021 in Abu Ali Sina hospital, Iran. All transplant recipients, older than 18 years were recruited. The patients received two doses of Sinopharm vaccine 4 weeks apart. Immunogenicity was evaluated through assessment of antibodies against the receptor-binding domain (RBD) of SARS-CoV-2 after the first and second dose of vaccine. The patients were followed up for 6 months after vaccination.ResultsOut of 921 transplant patients, 115 (12.5%) and 239 (26%) had acceptable anti S-RBD immunoglobulin G (IgG) levels after the first and second dose, respectively. Eighty patients (8.68%) got infected with COVID-19 which led to 45 (4.9%) of patients being hospitalized. None of the patients died during follow-up period. Twenty-four (10.9%) liver transplant recipients developed liver enzyme elevation, and increased serum creatinine was observed in 86 (13.5%) kidney transplant patients. Two patients experienced biopsy-proven rejection without any graft loss.ConclusionOur study revealed that humoral response rate of solid organ transplant recipients to Sinopharm vaccine was low.

Early Liver Transplant In Patients With Liver Cirrhosis Recovered From COVID-19 Infection.

OBJECTIVES: Coronavirus disease 2019 has resulted in significant morbidities and mortalities in nearly all parts ofthe world. There remain major concerns about management, timing, and safety of liver transplant in patients who have recovered from COVID-19. We aimed to study the clinical course and outcomes of patients with liver cirrhosis who recovered from COVID-19 and underwent liver transplant from deceased donors. MATERIALS AND METHODS: A retrospective study was conducted on liver transplant recipients who underwent liver transplant from April 1, 2020, to January 30, 2021. We evaluated all recipients of liver transplantfrom deceased donors during this period in the COVID-19 pandemic. RESULTS: There were 14 patients with decompensated liver cirrhosis who had recovered from COVID-19 as documented by reverse transcription-polymerase chain reaction test for SARS-CoV-2. Mean duration from COVID-19 to transplant surgery was 56.14 ± 29.96 days. Mortality occurred in 3 patients, and of whom 2 had been hospitalized and received medications for COVID-19 before transplant. Five patients had positive reverse transcription-polymerase chain reaction results for SARS-CoV-2 after liver transplant. CONCLUSIONS: This is a large reported series of patients with liver cirrhosis who have received liver transplant after recovery from COVID-19. We provided evidence that liver transplant from deceased donors should be considered in patients recovered from COVID-19, especially in those with deterioration of clinical status.

Clinical Evaluation of an HTK Solution for Liver Transplantation: A Phase 3 Randomized Pilot Clinical Trial Study.

BACKGROUND: Organ preservation solutions are not easily accessible in Iran, similar to many resource-limited countries. We aimed to evaluate the efficacy of a locally-produced HTK solution among adult liver transplantation candidates in a pilot clinical trial study. METHODS: Adult patients undergoing liver transplantation were randomly allocated into two groups. One received the HTK solution (PharMedCina Inc., Shiraz, Iran), and the second received the commercially available HTK solution (Custodiol ®). RESULTS: Overall, 28 individuals entered the study, including 11 and 9 males (78.6% and 64.3%) in the Custodiol® and local HTK groups, respectively. Clinical characteristics, including postoperative biliary complications, reperfusion syndrome, infection and primary non-function (PNF) rates, amount of intraoperative bleeding, length of hospital and ICU stay, peak aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and duration of follow-up were similar between the two groups (P>0.05). One patient died in the locally-produced HTK group. The patient underwent re-transplantation 20 days after his first liver transplantation due to PNF. Two patients died in the Custodiol group, both due to PNF of the liver, which occurred five and three days after transplantation. The two groups did not show any difference regarding serum levels of AST, ALT, alkaline phosphatase (ALP), bilirubin, platelet count, prothrombin time and international normalized ratio, white blood cell count, blood urea nitrogen, and creatinine on the first postoperative day and on the day of discharge (P>0.05). CONCLUSION: Based on the findings of this pilot study with the current sample size, no statistically significant difference was found between our locally-produced HTK solution and Custodiol® regarding clinical outcomes.

Nonalcoholic Steatohepatitis Is the Most Rapidly Growing Indication for Liver Transplantation in Iranian Patients.

OBJECTIVES: Nonalcoholic fatty liver disease is a rapidly growing disease and is hypothesized to become the most common cause of liver cirrhosis in the near future. This study aimed to investigate trends of nonalcoholic steatohepatitis as an indication for liver transplant in Iranian patients. MATERIALS AND METHODS: Liver transplant data from all adult patients (age > 18 y) who had undergone liver transplant between 1993 and 2017 at the Shiraz Organ Transplant Center (Shiraz, Iran) were reviewed. Underlying liver diseases leading to liver transplant were stratified according to year of transplant, and trends of increase or decline were analyzed. Kaplan-Meier curves were used for analysis of posttransplant survival of patients with nonalcoholic steatohepatitis and patients with modified nonalcoholic steatohepatitis. RESULTS: We evaluated 3184 liver transplant patients. Of these, 112 patients with biopsy-proven nonalcoholic steatohepatitis underwent liver transplant up to the end of 2017. Mean age of patients was 52.86 ± 9.01 years in those with nonalcoholic steatohepatitis and 51.73 ± 7.91 years in those with modified nonalcoholic steatohepatitis (P > .05).The prevalence of nonalcoholic steatohepatitis as an indication for liver transplant was 0.8% in 2011, 0.36% in 2012, 1.9% in 2013, 4.01% in 2014, 2.89% in 2015, 6.65% in 2016, and 9.97% in 2017. The prevalence of modified nonalcoholic steatohepatitis was 2.4% in 2011, 2.88% in 2012, 2.71% in 2013, 2% in 2014, 2.17% in 2015, 2.13% in 2016, and 2.28% in 2017. We found that nonalcoholic steatohepatitis as a cause of liver transplant increased significantly during recent years (P < .001). CONCLUSIONS: Nonalcoholic steatohepatitis is a rapidly growing indication for liver transplant among Iranian patients. Health care providers should consider programs for prevention and early diagnosis of patients with nonalcoholic steatohepatitis for proper treatment.

The Largest Single Center Report on Pediatric Liver Transplantation: Experiences and Lessons Learned.

OBJECTIVE: We described our experiences on pediatric liver transplantation (LT) from the largest LT center in the world termed the Shiraz Transplant Center. BACKGROUND: After the first successful pediatric LT in 1967, pediatric LT has become the routine treatment for children with liver failure worldwide. METHODS: Data on a total of 1141 pediatric cases of LT were collected. Specifics on baseline and anthropometric characteristics, clinicopathology, prognosis of recipients of LT, and donor characteristics are reported. RESULTS: Mean age of patients was 7.83 ±â€Š5.55 years old. Most common etiologies for LT were biliary atresia (15.9%), progressive familial intrahepatic cholestasis (13.4%), and Wilson's disease (13.3%), respectively.Whole organs, living donor grafts, and split grafts were used in 47.9%, 41%, and 11.1% of patients, respectively. In-hospital complications were seen among 34.7% of patients and the most common complications were infections (26.8%), bleeding (23.4%), and vascular complications (18%).Median (interquartile range) model for end stage liver disease score was 20 (15, 25). Main causes of death among patients were sepsis (35.2%), followed by post-transplantation lymphoproliferative diseases (10.5%), and primary nonfunction of liver (9%).Patient survival showed improvement over the years (1-year survival of 73.1%, 83.4%, and 84.4%, 2-year survival of 65.2%, 77.1%, and 78.7%, 5-year survival of 58.2%, 72%, and 77.8% for 1997-2007, 2007-2013, and 2013-2019, respectively; P < 0.001). CONCLUSIONS: This is the largest single-center report on pediatric LT in literature which provides valuable experiences in pediatric LT.

A Report of 85 Cases of COVID-19 and Abdominal Transplantation From a Single Center: What Are the Associated Factors With Death Among Organ Transplantation Patients.

BACKGROUND: In this study, we report the epidemiology of COVID-19 among recipients of organ transplantation and evaluate associated factors with death. METHODS: We screened 6969 patients who had organ transplantations in our center for COVID-19. Specific data on presentation, clinical course, treatment, and prognosis were acquired. RESULTS: We found 85 patients (66 liver, 16 kidney, 2 kidney-pancreas, and 1 liver-kidney recipient) who acquired COVID-19. Most common symptoms included fever (48.2%), cough (41.2%), myalgia (41.2%), and fatigue (40%). Dyspnea developed in 33% of patients. Overall, one-third of patients had an oxygen saturation of below 90% on admission. Patients were hospitalized for a median (interquartile range) of 9 (5, 13.7) days and had a 33.9% intensive care unit admission rate. Overall, 17 patients (20%) died, which included 31.3% of patients with kidney transplantations and 18.2% of patients with liver transplantations. All 4 pediatric patients in our series died. In our univariate analysis among adults, rates of leukopenia (38.4% versus 13.2%; P = 0.04), low albumin levels (53.8% versus 10.2%; P = 0.001), and shorter duration between transplantation and COVID-19 (P = 0.02), were higher among patients who died. In our least absolute shrinkage and selection operator regression model, low albumin levels (OR, 4.48; 95% confidence interval, 1.16-17.27) were associated with higher risk of death. CONCLUSIONS: This is the largest single-center report on abdominal transplantations and COVID-19. Liver and kidney transplant recipients have an increased risk of mortality compared with the general population due to COVID-19. More specifically, pediatric patients and those with low albumin levels are at higher risks of death due COVID-19.

Pediatric liver transplantation and COVID-19: a case report.

BACKGROUND: Immunosuppressed patients, including individuals with organ transplantation, have been among susceptible groups with regard to COVID-19, on the other hand pediatric patients more commonly undergo a mild clinical course after acquiring COVID-19. To the best of the authors knowledge, to this date very little data exists on COVID-19 in a pediatric patient with liver transplantation. CASE PRESENTATION: We report a three year-old boy who had liver transplantation at 18 months old. He was admitted due to dyspnea with impression of acute respiratory distress syndrome and was then transferred to the intensive care unit. Chest X-ray at admission showed bilateral infiltration. Vancomycin, meropenem, azithromycin, voriconazole and co-trimoxazole were started from the first day of admission. On day 4 of admission, with suspicion of COVID-19, hydroxychloroquine, lopinavir/ritonavir and oseltamivir were added to the antibiotic regimen. PCR was positive for COVID-19. The patient developed multi-organ failure and died on day 6 of admission. CONCLUSIONS: For pediatric patients with organ transplantations, extreme caution should be taken, to limit and prevent their contact with COVID-19 during the outbreak, as these patients are highly susceptible to severe forms of the disease.

Liver transplantation and COVID-19: a case report and cross comparison between two identical twins with COVID-19.

BACKGROUND: To this date little information exists on the effects, clinical course and outcome of the COVID-19 among patients undergoing transplantation. CASE PRESENTATION: A 35 year old male referred with loss of sense of smell and taste after having close contact with his brother who was diagnosed with COVID-19 five days prior to his symptoms. The patient had undergone liver transplantation 3 years prior to his referral due to primary sclerosing cholangitis in association with ulcerative colitis and was using immunosuppressive medications. The patient referred to a local physician with mild symptoms of fatigue, cough, myalgia, dizziness, and nausea/vomiting with a fear of contracting the disease. Except for a CRP of 32 his other blood tests were normal. After 3 days of hospital admission the patient was discharged with a good condition. His brother had developed fever, chills, headache, mild dyspnea and an objective loss of sense of smell and taste and was sent home and advised to self-quarantine. Both patients had CT scans in favor of COVID-19. CONCLUSION: Our patient who had liver transplantation and COVID-19 did not present more severe symptoms compared to his counterpart without liver transplantation and did not need to be hospitalized or be given antiviral drugs for COVID-19.

Single Center Long-Term Results of Pediatric Liver Transplantation.

OBJECTIVES: Liver replacement continues to be the only definitive mode of therapy for children with end-stage liver disease. However, it remains challenging because of the rare donor organs, complex surgical demands, and the necessity to prevent long-term complications. Our objectives were to analyze 16 years of experience in the Shiraz University Organ Transplant Center. MATERIALS AND METHODS: We retrospectively analyzed the records of 752 patients (< 18 years old) who underwent orthotopic liver transplant at our center over a 16-year period. Mean age was 90 months, and male-to-female ratio was 1.25. Of the 752 transplants, 354 were whole organs, 311 were from living related donors, and 87 were in situ split liver allografts. Patient and graft survival rates were determined at 1, 3, and 5 years, and results between groups were compared. RESULTS: Overall mortality was 31.8%. The 1-, 3-, and 5-year patient survival rates were 77%, 69%, and 66%, respectively, whereas the respective graft survival rates were 75%, 68%, and 65%. We observed significant differences in survival according to graft type (log-rank test, P < .001). We also observed significant differences in survival probabilities according to age (log-rank test, P < .001). Cox regression was used to simultaneously analyze effects of age and graft type on survival. Both graft type and age significantly affected survival (P < .001). The 1-, 3, and 5-year survival rates for patients having whole organ transplants were 88%, 81%, and 78%. Patients who received living donor grafts had respective survival rates of 66%, 60%, and 58%, with rates of 65%, 47%, and 47% for patients who received split grafts. CONCLUSIONS: Our results were similar to those observed in the literature in terms of indication for transplant and posttransplant survival.

Portal vein thrombosis in patients with liver cirrhosis and its impact on early and long-term outcomes after liver transplantation.

AIM: Portal vein thrombosis (PVT) is a common complication amongst patients with liver cirrhosis. The PVT risk factors and its impact on post liver transplant outcome has not been well defined, yet. This study aimed to investigate PVT prevalence, its risk factors and influence on early and long-term outcomes after liver transplantation. METHODS: Adult (>18 years) patients with liver cirrhosis undergoing liver transplantation between March 2013 to March 2015 were included. Presence or absence of PVT was recorded at transplant. PVT risk factors in patients with liver cirrhosis and its impact on early and long-term outcomes were analysed. RESULTS: Portal vein thrombosis was diagnosed in 174 patients (17.3%). Large oesophageal varices (grade II and III vs grade I) (OR: 2.5; 95% CI: 1.46-4.26; P = 0.001), diabetes mellitus before transplantation (OR: 2.03; 95% CI: 1.13-3.64; P = 0.017) and cryptogenic-NASH (OR: 1.36; 95% CI: 1.08-1.72; P = 0.008) as a cause of underlying liver disease were the independent risk factors for PVT. PVT (OR: 2.05; 95% CI: 1.10-3.81; P = 0.023) was an independent predictor of early (within 90 days) posttransplant mortality, but did not influence long-term survival. CONCLUSION: Portal vein thrombosis prevalence is high in pretransplant period. NASH related cirrhosis and diabetes mellitus might be risk factors for PVT. More intense screening of these patients for PVT is warranted.

A New Consideration in Hepatic Artery Reconstruction in Adult Liver Transplant: Arterial Transposition Versus Extra-Anatomic Jump Grafts.

OBJECTIVES: In some cases of liver transplant, standard hepatic artery reconstruction may be difficult or impossible due to inadequate flow of the recipient's hepatic artery, as a result of stenosis, intimal dissection, or anomalies of the hepatic artery. We compared splenic artery transposition with extra-anatomic jump graft as 2 alternative methods for hepatic artery reconstruction in these situations. MATERIALS AND METHODS: We reviewed the files of 2135 liver transplant recipients from March 2011 to February 2016 at the Shiraz Transplant Center. Data of 93 patients with unusual hepatic artery reconstruction were analyzed to assess outcomes, morbidity, mortality, and pre- and posttransplant parameters (both clinical and paraclinical). Patients were divided into 2 groups: 17 with splenic artery transposition (splenic artery group) and 76 with extra-anatomic jump grafts (control group). RESULTS: There was only 1 occurrence (5.8%) of hepatic artery thrombosis in the splenic artery group causing extra-anatomic jump graft. However, in the control group, there were 4 occurrences (5.2%) of hepatic artery thrombosis, causing 1 revision of anastomosis and 3 retransplant procedures. No deaths due to hepatic artery complications were reported in the 2 groups. Three-year survival rate was 87.5% in the splenic artery group and 68.9% in the control group. CONCLUSIONS: Splenic artery transposition is an acceptable method for hepatic artery reconstruction in deceased-donor liver transplant procedures with no greater rates of complication or morbidity than extra-anatomic jump grafts. Less operation time and better exposure during surgery are advantages of this method.

Impact of a Full-Time Donor Management Protocol on Donors' Liver Biopsy Findings: Progress to Date.

OBJECTIVES: This study investigated a fixed coordinator-directed donor management strategy's impact on donated liver quality, as determined by definitive biopsy results. MATERIALS AND METHODS: We collected donated liver biopsy results from donations both before and after implementing a fixed coordinator-directed donor management strategy. This strategy involved full-time attendance by a donor coordinator and continued resuscitation of brain-dead donors. All donations took place in a single organ procurement unit. We also followed up results of biopsies from the Liver Transplantation Center database of Namazi Hospital in Shiraz, Iran. RESULTS: We compared biopsy findings of 192 livers donated from 2012 to 2013 (group A) with 276 livers donated from 2015 until August 2016 (group B). Data analysis showed that 67 livers (34.9%) in group A were rejected for transplant owing to severe steatosis in 17 (8.9%), moderate/severe fibrosis in 9 (4.7%), moderate/severe necrosis in 28 (14.6%), and 13 (6.8%) rejected for other pathologies. Among group B livers, 59 (21.4%) were not deemed suitable for transplant owing to severe steatosis in 37 (13.5%), moderate/severe fibrosis in 6 (2.1%), and moderate/ severe necrosis in 16 (5.7%). Overall, steatosis was found in 94 livers (49.2%) in group A versus 175 livers (63.3%) in group B (P = .007). Donor age in group A averaged 36.5 years versus 47.9 years in group B (P = .02). Necrosis was found in 33 livers (17.2%) in group A and 22 livers (7.9%) in group B (P = .008). One-month survival rates were 95.3% and 96.3% for groups A and B (P = .08). CONCLUSIONS: Donated liver disqualification before transplant noticeably decreased despite the shift in demographic patterns from 2012 to 2016. In group A, brain-dead liver donors were younger and more often died from trauma, whereas group B donors had more cerebrovascular accident-induced deaths. This achievement took place alongside increased rates of steatosis and decreased rates of necrosis.

Transplantation of Deceased Donor Livers With Elevated Levels of Serum Transaminases at Shiraz Transplant Center.

BACKGROUND: The current organ shortage has prompted the use of marginal organs. We conducted this retrospective study to present our experience with transplanting deceased donor livers with elevated levels of serum transaminases and to explain whether elevated levels of serum transaminases in donors affect allograft function and survival of the recipients. METHODS: Data of deceased donor livers and patients, who underwent liver transplantation from March 2013 to March 2015 at Shiraz center for organ transplantation, was reviewed. Liver donors with aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) level of more than 500 IU/l and their related recipients were considered as the case group (n = 24) and the others were considered as the control group (n = 834). RESULTS: In the case group, the medians of levels of serum AST and ALT of donors were 834 ± 425 IU/L (range: 250 - 2285) and 507 ± 367 IU/L (range: 100 - 1600), respectively. Recipients were followed for a median of 13.6 ± 9 months (range: 7 - 28.4). Post-transplant complications were acute rejection (n = 5), infection (n = 3), portal vein thrombosis (n = 3), bile duct stricture (n = 1), and hepatic artery stenosis (n = 1). The one-year survival rate of the patients was 91.7%. Demographics, post-transplant complications and one-year survival rates were not significantly different between the two study groups. CONCLUSIONS: Transplanting deceased donor livers with markedly elevated liver enzymes may be an acceptable choice for expanding the donor pool.

Partial replacement of left hemidiaphragm in dogs by either cryopreserved or decellularized heterograft patch.

OBJECTIVES: Large diaphragmatic defects are still a challenging issue for reconstruction using either synthetic prosthesis or bioprosthesis. To evaluate the possibility of using diaphragm allograft as a natural bioprosthesis in humans, we conducted a two-group study and compared cryopreserved and decellularized diaphragmatic heterograft patched in a canine model. METHODS: At the end of organ harvesting from a human donor, the left hemidiaphragm was taken to the laboratory in phosphate-buffered saline solution. The next step was freezing the grafts at -80°C, and preserving them for up to 2 months in Group 1. It was subjected to a detergent-enzymatic method (containing sodium deoxycholate/DNase lavations) of decellularization for 25 cycles in Group 2. Through left thoracotomy in the eighth intercostal space, cryopreserved patches in six dogs and decellularized patches in five dogs replaced the diaphragm. During the follow-up, sonography was done in all animals, but three and two dogs in Group 1 and 2 underwent computed tomography (CT) scan, respectively. The animals were euthanized after 6 months. RESULTS: There was no mortality. Sonography showed only motion impairment of the patches in all cases. In Group 1, CT scan showed mild atelectasis and scattered infiltration in the left lower lobe, fibrotic bands and minimal fluid collection under the diaphragm. In Group 2, CT scan showed scattered fibrotic bands and mild to moderate elevation of the left hemidiaphragm. There was no evidence of gross disruption and complete healing of the suture line. Necropsy in both groups showed patches were completely replaced with a dense fibrous tissue. In Group 1, focal calcification was noticeable in every case and foreign body-type granulomas were clearly seen all over the grafted tissue. Histology in Group 2 animals showed less inflammatory cell infiltration and scattered foreign body granulomas in comparison with the cryopreserved patch graft. CONCLUSIONS: The gross healing process in the decellularized heterograft is similar to the cryopreserved diaphragm but with fewer inflammatory cells and foreign body granulomas on histology. Both of them can be used instead of bioprostheses with regard to the fact that the decellularized patch technique is more complex and expensive. It is recommended to compare them with commercial bioprostheses.

Modified Multivisceral Transplant After Acute Abdominal Trauma.

A 50-year-old man sustained blunt abdominal trauma in a motor vehicle accident. He underwent exploratory laparotomy on the day of trauma, and severe bleeding from the base of the small bowel mesentery was controlled by mass ligation and through-and-through suturing. After transfer to our center, repeat exploratory laparotomy showed ischemic small intestine, ischemic right colon, and severe pancreatic trauma. The severely injured organs were excised including the entire small bowel, pancreas, spleen, stomach, and right hemicolon. The next day, a modified multivisceral transplant was performed including stomach, pancreaticoduodenal complex, and small bowel transplant. Postoperative complications included an intra-abdominal collection that was drained percutaneously with ultrasonographic guidance and severe rejection that was treated with anti-thymocyte globulin. In summary, for select patients who have severe abdominal trauma may be treated with acute multivisceral transplant.

Predictors of tumor-free survival after liver transplant in patient with hepatocellular carcinoma.

OBJECTIVES: To identify the predictors of overall survival and tumor-free survival of 88 hepatocellular carcinoma patients who were treated with orthotopic liver transplant at Shiraz Organ Transplant Center. MATERIALS AND METHODS: We performed this retrospective study after reviewing the transplant database of all patients who underwent orthotopic liver transplant secondary to hepatocellular carcinoma and liver cirrhosis. Hepatocellular carcinoma was diagnosed in 70 patients before liver transplant and 18 patients on histologic examination of the explanted livers. Cox regression identified independent factors that affected posttransplant survival. RESULTS: The overall survival rate was 83% and the tumor-free survival rate was 79.5%. Independent factors for tumor recurrence were Milan criteria, alpha-fetoprotein level before operation ≥ 400 ng/mL, tumor grade, vascular invasion, and age. Vascular invasion (odds ratio, 5; 95% confidence interval, 1.1 to 25.496; P = .049) and tumor grade (odds ratio, 14.42; 95% confidence interval, 3.652 to 56.95; P < .001 were statistically significant. CONCLUSIONS: Vascular invasion and tumor grade were predictive factors for tumor-free survival.

En-bloc liver-pancreas transplant in Iran.

Liver transplant can be challenging in cirrhotic patients with diabetes mellitus. In chronic liver disease, the glucose metabolism is altered; uncontrolled diabetes negatively influences the outcome of liver transplantation and poses difficulty in the management of immediate post transplantation period. Simultaneous liver-pancreas transplantation is an option to prevent early complications due to diabetes and also to improve the quality of life after transplantation in patients with Insulin-Dependent Diabetes Mellitus (IDDM) and chronic liver disease. We report the first en-bloc liver-pancreas transplant done in the transplant history of Iran. We describe the technical details of the procedure as well as the short term outcome after transplantation. In this case report, we also discuss in some details, the surgical, medical and immunological advantages of combined liver-pancreas transplantation as opposed to separate implantation of both organs.

Discarded organs at Shiraz Transplant Center.

OBJECTIVES: This study sought to investigate discarded organs at the Shiraz University of Medical Sciences, Shiraz, Iran. MATERIALS AND METHODS: We performed a retrospective analysis of Shiraz Transplant Center database regarding discarded organ during May 2010 and December 2013. Our study investigated 80 unused liver donors' characteristics. The data included age, sex, cause of discard, cause of brain death, hypotension during hospitalization of donors, and result of liver biopsy. RESULTS: Among 780 grafts, 80 livers (10.25%), between May 2010 and December 2013, were unsuitable for transplant. Among the donors whose livers were discarded, 36 were women (45%) and 44 were men (55%) (mean age, 43.7 ± 14 years; range, 1-67 y). The most common causes of brain death were cerebrovascular accidents 27 (33.8%), trauma 27 (33.8%), aneurysm, and subarachnoid hemorrhage 13 (16.3%). The most common cause of unused organ were fatty liver 50 (62.5%) and necrosis 25 (31%) (steatosis more than 40%). CONCLUSIONS: Old age, cerebrovascular accidents, and severe steatosis ≥ 40 were the most common associated factors in organ discard in this study.

Reducing Social Disparity in Liver Transplantation Utilization through Governmental Financial Support.

BACKGROUND: A high proportion of patients suffering from end stage liver disease are from low socioeconomic classes , which limits their access to liver transplantation as the most effctive treatment of this condition because of cost barrier. OBJECTIVES: one of the most challenging aspects of liver transplantation is its affordability and utilization by those who need it the most. PATIENTS AND METHODS: Since November 2005, Iran Ministry of Health had covered 100% of the costs of in-patient liver transplantation care. To determine the effects of this policy, patterns of utilization of liver transplantation were compared before and after implementation of the policy. Group one included 112 and group two included 120 individuals who received transplantation before (from early January 2003 to November 2005) and after (from November 2005 to the end of December 2007) the legislation entered into the effect, respectively. Socioeconomic characteristics of these patients were evaluated by data collected about house and car ownership, education level, employment status, and place of residence. RESULTS: Coverage of the costs allowed more illiterate and semiliterate people (P = 0.032) as well as more unemployed or unskilled workers to receive transplantation (P = 0.021). The number of transplantations also increased in children and geriatric age group. This legislation also led to greater countrywide regional coverage of indigent patients. CONCLUSIONS: This survey provides evidence that coverage of the costs by Ministry of Health was effective in reducing social discrimination in utilization of liver transplantation, and narrowed the gap between low and high socioeconomic classes in Iranian society.

Tacrolimus related hypertrophic cardiomyopathy in liver transplant recipients.

BACKGROUND: Recently there are a number of reports on the cardiotoxicity of tacrolimus in post-transplant patients. There is no protocol for cardiovascular evaluation in these patients. This study was performed to evaluate the cardiotoxicity of tacrolimus in liver transplant recipients. METHODS: We evaluated 63 post-liver transplant patients who received tacrolimus. They were evaluated for cardiovascular complications by physical examination, electrocardiographic and echocardiographic examinations within three and six months following liver transplantation. Serum tacrolimus levels were checked by ELISA. For comparison, we selected 50 post-liver transplant patients who received no tacrolimus and evaluated them for cardiovascular function identically. RESULTS: Among 63 patients, 42 were male (66.7%) and 21 were female (33.3%); 70% of the patients were adults, and 19 (30%) were within the pediatric age group. The cardiovascular examinations, electrocardiogram and echocardiography of all patients three months post-transplantation were normal except for two children who developed tacrolimus related cardiac complications. Both had high serum tacrolimus levels. No adults developed cardiovascular complications. In the control group, the results of the cardiovascular evaluations were normal in all cases. CONCLUSION: The cardiovascular toxicity of tacrolimus, such as hypertrophic cardiomyopathy, may be observed in pediatric patients. Therefore, we recommend routine regular cardiovascular evaluation of children after liver transplantation.
