ABSTRACT

Background: Marital satisfaction is one of the important components of quality of life. Women's marital satisfaction is affected when they enter the middle age period, due to the mental and emotional tensions caused by the physical changes. In this regard, the present study aimed to investigate the association of quality of life with marital satisfaction, stress, and anxiety in middle-aged women referring to health centers of Ahvaz city, Iran. Methods: This cross-sectional descriptive-analytical study was conducted on 1,000 middle-aged married women (30-59 year of age) under the auspices of health centers of Ahvaz city, Iran in 2019. The subjects were selected by simple random sampling method, and were asked to complete demographic characteristics, quality of life questionnaire, Enrich marital satisfaction questionnaire, Holmes-Raheh stress questionnaire, and Spielberger state-trait anxiety inventory. The data were analyzed by using SPSS 0.22 software through mean, standard deviation, frequency, Pearson correlation and regression (p = 0.05). Results: Based on the results, 42.4% of the participants were between 40 and 50 years of age, 35.6% had a high school diploma, and 50% of them were housewives. Also, the results of Pearson's correlation showed a positive and significant relationship between quality of life and marital satisfaction (r = 0.178) (p < 0.001). However, quality of life had a negative and significant relationship with anxiety (r = -0.552) (r < 0.001) and stress (r = -0.188) (p < 0.001). Conclusion: Given the positive and significant relationship between quality of life and marital satisfaction, appropriate trainings are highly recommended for couples to increase the quality of life and marital satisfaction of middle-aged women and thus strengthen the health of family and society.

ABSTRACT

BACKGROUND: Chronic liver disease (CLD) in children, often leads to cirrhosis and end-stage liver disease (ESLD). CLD poses significant challenges in management and prognosis. Assessing body composition, including sarcopenia, is increasingly recognized as important in understanding outcomes in this population. METHODS: We conducted a prospective observational study, involving children aged 2 to 18 years with ESLD awaiting liver transplantation. Socio-demographic, clinical, and laboratory data were collected, and body composition was assessed using Bioelectrical Impedance Analysis (BIA). Sarcopenia was defined using age-specific cut-off points for appendicular skeletal muscle mass (aSMM) and fat-free mass (FFM). RESULTS: The study included 57 children (42.1% girls, 57.9% boys; median age: 10.9 years) with liver cirrhosis. Of them 11 (19.3%) died during the study. The mean duration of living with end-stage liver disease prior to participation was 5.43 years [IQR: 3.32, 8.39]. The most common etiology was biliary atresia (24.6%), followed by cryptogenic (22.8%). Deceased children exhibited significantly higher sarcopenia prevalence, lower basal metabolic rate and growth scores compared to survivors (P < 0.05), (771.0 vs. 934.0, P = 0.166) (65.0 vs. 80.5, P = 0.005). Total body and limb-specified lean mass were lower in deceased children, although not statistically significant. Similarly, total mineral (90% normal) and bone mineral content were lower in deceased children, with a significant difference observed only in water-to-FFM percentage (72.5 vs. 73.1, P = 0.009). CONCLUSION: This study highlights the high prevalence of sarcopenia among children with ESLD and its association with adverse outcomes, including mortality. Bioimpedance analysis emerges as a promising, non-invasive method for assessing body composition in pediatric ESLD, warranting further investigation and integration into clinical practice.

ABSTRACT

OBJECTIVES: The recurrence of underlying diseases remains a major cause of graft failure after liver transplant. This study aimed to identify factors associated with the recurrence of underlying diseases and investigate the incidence of these factors and recurrence at the main liver transplant center in Iran. MATERIALS AND METHODS: We included adult liver transplant recipients followed at Shiraz Transplant Center between 2011 and 2018 with a confirmed diagnosis of recurrence of underlying disease in our study. We reviewed medical records and extracted data on demographic characteristics, clinical and paraclinical features, medication use, and current status. We used a systematic random sampling method to select a control group of 95 transplant recipients who did not have recurrence. Of 3022 total transplant recipients, 76 recipients experienced a recurrence of their underlying disease. RESULTS: Model for End-Stage Liver Disease score, underlying disease, recipient blood group, donor sex, donor blood group, and rejection frequency were significantly different between study groups with and without recurrence of underlying diseases. Liver transplant recipients with recurrence had lower mean Model for End-Stage Liver Disease score. Recipients with recurrence also had higher rate of drug consumption (eg, prednisolone, tacrolimus, mycophenolate mofetil, sirolimus). Regression analysis showed that donor sex and rejection frequency had an effect on disease recurrence. Death occurred more frequently in liver transplant recipients with recurrence than in the control group (39.5% vs 26.3%), butthe difference was not significant. CONCLUSIONS: Donor sex and acute rejection frequency are independent factors predictive of the recurrence of underlying disease. Modifying risk factors can help minimize the recurrence of underlying diseases after liver transplant.

ABSTRACT

Aim: The purpose of this retrospective single-center study was to determine the frequency of sarcopenia and its association with mortality and other morbidities in children with chronic liver disease who had undergone liver transplantation. Background: Sarcopenia, a muscle-wasting syndrome, is common in patients with advanced liver disease and is associated with increased morbidity and mortality. While sarcopenia in adults has been extensively studied, there is little information in this regard about children and adolescents with chronic liver diseases. Methods: The study included 108 children and adolescents who had undergone liver transplantation. Sarcopenia was measured using skeletal muscle index at the third lumbar vertebral level and assessed using abdominal computed tomography imaging. Results: The frequency of sarcopenia in the studied population was found to be 45.7%. Patients with sarcopenia were more likely to be male (P<0.0001), older (P<0.0001), and had lower height-for-age z-scores (P=0.012). Genetic/metabolic diseases were the most common underlying cause of sarcopenia in children. Except for a higher rate of transplant rejection in the sarcopenia group (P=0.035), there was no significant difference in mortality rates (P=0.688) or post-LT complications between the two groups. One year after LT, computed tomography-derived body composition parameters revealed no significant differences between children who survived and those who did not. Conclusion: Our findings indicated a high frequency of sarcopenia in children with chronic liver disease, implying that more research is needed to better understand its impact on clinical outcomes in this population.

ABSTRACT

Biliary atresia (BA) is the primary cause of neonatal jaundice with various pathological mechanisms. Many BA patients may experience progressive liver dysfunction and eventually need a liver transplant. Therefore, identifying potential non-invasive biomarkers for BA is crucial. miR-122, the most abundant microRNA in the liver, plays significant roles in different liver diseases. This study aimed to assess miR-122 levels in BA patients. Eighteen patients with biliary atresia were selected at random from the Shiraz Pediatric Liver Cirrhosis Cohort Study (SPLCCS), along with 18 healthy controls. Blood samples were collected, and biochemical parameters (such as liver function tests) were measured. Quantitative reverse-transcription PCR (RT-PCR) was conducted on serum samples from both the case and control groups to analyze miR-122 levels. The study results indicated that serum miR-122 expression in BA patients was elevated compared to the control group, although it did not reach statistical significance. Additionally, no correlation was found between miR-122 expression and serum levels of liver enzymes or other laboratory findings in BA cases. miR-122 could be a potential target for diagnosing BA; however, further research with a larger population is necessary to determine if miR-122 could serve as a useful biomarker for diagnosing BA.

ABSTRACT

OBJECTIVES: Identification of chronic rejection risk factors in liver transplant recipients is critical for early detection and prevention of further graft loss. We investigated characteristics of liver transplant recipients who had experienced chronic rejection and the associated risk factors versus patients without chronic rejection. MATERIALS AND METHODS: Data from 3022 adult liver transplant recipients between 2011 and 2018 were analyzed; of these, 80 patients had experienced chronic rejection. The control group included 98 randomly selected liver transplant recipients who did not have chronic rejection. RESULTS: The age of the recipients and the donors was significantly lower in the group with chronic rejection versus the group without chronic rejection.The results indicated that chronic rejection was significantly associated with the sex of the recipients (hazard ratio 3.2, 95% CI 1.77-6.08; P < .001) and with the sex concordance between the recipients and donors (hazard ratio 2.93, 95% CI 1.67-5.13; P < .001, respectively). Also, in the group without chronic rejection, there were no male donors; however, the group with chronic rejection had mostly male donors (P <.001). Cold ischemia time was longer in patients with chronic rejection versus that shown in the control group (P = .031), and there was a significant difference between the 2 groups in acute rejection frequency (P < .001). CONCLUSIONS: Recipient sex and sex concordance were independent risk factors for chronic rejection. Most transplantrecipients with chronic rejection responded to medicaltreatment, and the rate of graftloss was low among our recipients.

ABSTRACT

Background MicroRNAs (miRNAs) are a group of small non-coding RNAs that bind to the target mRNA and regulate gene expression. Recently circulating microRNAs were investigated as markers of diseases and therapeutic targets. Although various studies analyze the miRNA expression in liver disease, these studies on PFIC are few. Progressive familial intrahepatic cholestasis (PFIC) is a rare liver disease with autosomal recessive inheritance. Most children with PFIC progress to cirrhosis and liver failure and consequently need to have a liver transplant. The aim of this study is the investigation of the miR-19b and miR-let7b expression levels in Iranian PFIC children. Methods 25 PFIC patients, 25 healthy children and 25 Biliary Atresia patients were considered as case and two control groups respectively. Blood samples were obtained and Liver function tests (LFTs) were measured. After RNA extraction and cDNA synthesis, quantitative PCR was performed using specific primers for miR-19b and miR-let7b. The U6 gene is used as an internal control. Results qPCR on PFIC patients’ samples demonstrated that the miR-19b and the miR-let7b expression were significantly decreased in patients compared to the control groups, with a p-value<0.0001 and p-value=0.0006 receptively. Conclusion In conclusion, circulating micro-RNA like miR-19b and miR-let7b have a potential opportunity to be a non-invasive diagnostic marker or therapeutic target for PFIC in the future (AU)


Antecedentes Los microRNA (miRNA) son un grupo de pequeños RNA no codificantes que se unen al ARNm diana y regulan la expresión génica. Recientemente se han investigado los microRNA circulantes como marcadores de enfermedades y dianas terapéuticas. Aunque varios estudios analizan la expresión de miRNA en enfermedades hepáticas, estos estudios sobre PFIC son escasos. La colestasis intrahepática familiar progresiva (PFIC) es una enfermedad hepática rara con herencia autosómica recesiva. La mayoría de los niños con PFIC progresan a cirrosis e insuficiencia hepática y, en consecuencia, requieren de un trasplante de hígado. El objetivo de este trabajo es la investigación de los niveles de expresión de miR-19b y miR-17b en niños iraníes con PFIC. Métodos Se consideraron 25 pacientes con PFIC, 25 niños sanos y 25 pacientes con atresia biliar como grupos de casos y controles. Se obtuvieron muestras de sangre y se midieron las pruebas de función hepática (LFT). Después de la extracción de RNA y la síntesis de cDNA, se realizó PCR cuantitativa usando cebadores específicos para miR-19b y miR-17b. El gen U6 se utiliza como control interno. Resultados La qPCR en muestras de pacientes con PFIC demostró que la expresión de miR-19b y miR-17b disminuyó significativamente en los pacientes en comparación con dos grupos de control, con un valor de p<0,0001 y un valor de p=0,0006, receptivamente. Conclusión En conclusión, los micro-RNA circulantes, como miR-19b y miR-let7b, tienen una oportunidad potencial de ser un marcador de diagnóstico no invasivo o un objetivo terapéutico para PFIC en el futuro (AU)

ABSTRACT

Background: Metabolic syndrome (MetS) is a set of conditions that occur together and increase the risk of cardiovascular disease. Previous studies have linked a gluten-free diet (GFD) to obesity and MetS in some populations. However, others have suggested that weight gain is usually regulated only in underweight individuals with celiac disease (CD). Owing to the lack of sufficient data and the importance of GFD in controlling cardiovascular disease, we surveyed the prevalence of MetS and its components before and after a year of GFD in patients referred to the main celiac clinic in southern Iran. Methods: This was a repeated cross-sectional study conducted on 69 patients with a definite diagnosis of cardiovascular disease who were on follow-up and registered at the Shiraz Celiac Clinic. Demographic, anthropometric, and laboratory measurements at the time of diagnosis and one year after the GFD were extracted from their medical records. Results: The participants' mean age was 35.53, and 68.1% were women. The prevalence of MetS increased from 5.8% to 11.6% after a year of the GFD; however, this increase was not statistically significant. Waist circumference (WC) and serum triglyceride levels were significantly elevated during the study period. Conclusion: A GFD may contribute to the development of MetS in patients with cardiovascular disease; however, the rate of MetS is still lower than that in the general population. It is critical to educate patients about these potential risks and encourage them to have a healthy lifestyle that includes a balanced diet and physical activity.

ABSTRACT

OBJECTIVES: Prolonged tracheal intubation and mechanical ventilation after liver transplant increase postoperative complications. Hence, timely extubation should be considered; however, a standard clinical criteria set or scoring system to select patients has not been established for early extubation after livertransplant.We investigated the factors that affect early extubation to design a predictive scoring system for early extubation. MATERIALS AND METHODS: This study is a case-control study of adult liver transplant patients. Preoperative, intraoperative, and postoperative clinical data were collected. Early extubation was defined as tracheal extubation immediately or up to 6 hours posttransplant. The variables were compared between the early extubation group and the delayed extubation (>6 hours) group. RESULTS: Our study enrolled 237 patients; among them, 57 patients (24%) were in the early extubation group, and 180 (76%) were in the delayed extubation group. Multiple logistic regression analysis showed that postoperative base excess level at admission to the intensive care unit, number of units of packed red blood cells transfused during surgery, urine volume, and excess base level 6 hours after surgery were the main predictors of successful early extubation. CONCLUSIONS: The initial base excess level at the entrance to the intensive care unit(postsurgery) and 6 hours after surgery, packed red blood cell volume transfused during surgery, and urine volume 6 hours after surgery are the main predictors for a successful early tracheal extubation.These factors are considered for the Shiraz Extubation Predictor formula.

ABSTRACT

BACKGROUND: Children receive transplants at a younger age, and the period of immunosuppression therapy may extend over decades. However, immunosuppression seems to be responsible for long-term mortality and morbidity. Pediatric liver transplant recipients can benefit from achieving immune tolerance and the opportunity of freedom from lifelong immunosuppression. This study aimed to investigate the frequency of prope tolerance among pediatric liver transplant recipients and the characteristics of these patients. METHODS: In this retrospective cohort study of pediatric liver transplant recipients, the medical records of transplant recipients treated at Shiraz Organ Transplant Center between 1994 and 2017 were reviewed. Prope tolerance was defined as normal laboratory values and stable clinical status on low-dose monotherapy. Children treated with low-dose monotherapy were categorized as the prope tolerant group. We compared the characteristics of prope tolerant recipients on low-dose monotherapy with patients on standard immunosuppression, i.e. full-dose tacrolimus plus steroids and mycophenolate mofetil. The data were analyzed with the t-test, chi-squared test, and a Cox proportional hazard model at a 5% significance level in SPSS software version 16. RESULTS: A total of 585 children with a mean age of 8.32 ± 5.23 years were enrolled. 341 patients were categorized as prope tolerant and 244 comprised the full immunosuppression regimen group. Mean age at transplantation and rejection frequency were lower in the prope tolerant group (p < 0.001, p < 0.001). Based on the underlying diseases, metabolic/genetic, biliary tract, and cryptogenic liver diseases were significantly more prevalent in the prope tolerant group (p < 0.001). However, autoimmune liver disease was found to be more prevalent in the full immunosuppression regimen group. Also, those who received living organs (p = 0.001) and recipients of organs from female donors had a greater likelihood of achieving prope tolerant. According to the multiple Cox regression results, age at transplantation (p = 0.022), rejection frequency (p < 0.001), and autoimmune liver diseases (p = 0.028) had a prognostic effect on prope tolerance. CONCLUSION: Factors as underlying disease, age at transplantation, and rejection frequency were factors that were predictive of prope tolerance in this sample of children. However, the risk of rejection should be considered during the tapering period.

ABSTRACT

Liver diseases in children and adolescents are a significant and arising public health issue and should be surveyed from different dimensions (clinical and para-clinical, psychological, socio-economic) and in diverse populations. Shiraz Liver Transplant Center, Shiraz, Iran is the only center for pediatric liver transplantation and its pre-operative evaluations. This provides a unique and valuable situation for studying this vulnerable population. The Shiraz Pediatric Liver Cirrhosis Cohort Study (SPLCCS) was established to assess cirrhotic children, the course of their disease, and treatment over time. This cohort study aimed to prospectively evaluate the natural course and factors that contributed to complications and death of children with chronic liver disease in the region. SPLCCS was launched in September 2018 after obtaining ethical approval; until August 2022, 370 children with end-stage liver disease were enrolled and followed every six months. Here, the cohort's features, the included population's baseline characteristics, and primary outcomes are reported.

ABSTRACT

Aim: This review sought to evaluate the significance of a functional assessment for liver transplant candidates, i.e., frailty, in the pre-transplant setting and its association with mortality and morbidities. Background: Liver transplantation (LT) remains the treatment of choice for patients with end-stage liver disease. Due to the shortage of organs for LT, a careful selection of suitable recipients is essential. Frailty, a measure of physiologic reserve and increased vulnerability to stressors, was initially used in geriatrics and then introduced to the field of transplantation for better patient selection. Methods: PubMed, Scopus, and Web of Science databases were reviewed up until January 2023. The search terms included: "frail*", "liver", and "transplant*". A Meta-analysis was conducted for the hazard ratios (HRs) obtained from the COX regression models. Fifty-five studies were included in this review; ten were included in the meta-analysis. Results: The prevalence of frailty varied from 2.82% to 70.09% in the studies. Meta-analysis showed that overall frailty had a significant association with mortality (pooled adjusted HR [95%CI]: 2.66 [1.96-3.63]). Subgroup analyses revealed that both the Liver Frailty Index and Fried Frailty Index were significantly associated with mortality. Furthermore, these studies have demonstrated that this population's frailty is associated with ascites, hepatic encephalopathy, and esophageal varices. Conclusion: According to emerging evidence, frailty is associated with increased morbidity and mortality of the patients on the LT waiting list. Further randomized trials are required to determine the efficacy and safety of variable interventions in the frail population.

ABSTRACT

BACKGROUND: Liver transplantation (LT) is considered the only treatment for patients with end-stage liver disease and, despite its incredible impacts on the patients' health status, places them in an immunocompromised state in which opportunistic infection would find a way to present. Latent tuberculosis infection (LTBI) is the most common form of TB and can be diagnosed through tuberculin skin test (TST) or Interferon-Gamma Release Assays (IGRA). LT recipients are at significant risk of TB activation. There is no strict guideline to approaching these cases though, in most centers, Isoniazid (INH) would be prescribed prophylactically. INH is a hepatotoxic medication and can have adverse effects on the transplanted liver. There is no consensus on this issue; therefore, we aimed to survey the potential hepatotoxic effects of INH among LT recipients in Shiraz, Iran. METHODS: A retrospective cohort study was conducted among LT candidates and recipients at Abu Ali Sina Organ Transplantation Center between 1993 and 2019. All the cases underwent TST and chest X-ray to detect LTBI. All the LTBI were treated with INH from 6-9 months and followed by the level of liver enzymes for quick detection of hepatotoxicity. A control group was selected among LT recipients and matched for age, gender, MELD score, and donor age. RESULTS: Among 4895 medical records reviewed, 55 (1.12%) cases had LTBI. Neither INH-related hepatotoxicity, nor signs and symptoms that were suspicious to TB reactivation were reported. Overall, three deaths were reported, two because of myocardial infarction and one due to pneumonia. Ten patients (18.2%) experienced acute rejection as confirmed with pathology and responded to methylprednisolone. Aspartate aminotransferase (AST) was diminished from pre-LT time to the first time after transplantation; after that, it showed a steady pattern. Meanwhile, Alanine transaminase (ALT) was constant before and one stage later and decreased after that. Statistical analyses only showed significant changes in the total bilirubin titer between the case and control groups. CONCLUSION: This survey showed prophylactic management of LTBI with INH in LT candidates and recipients was associated with no hepatotoxicity or related death. It seems that INH prophylaxis is safe in LT settings and can efficiently prevent TB activation; however, careful monitoring for adverse effects and liver enzymes elevation is highly recommended.

ABSTRACT

BACKGROUND: Tissue engineering is considered as a promising tool for remodeling the native cells microenvironment. In the present study, the effect of alginate hydrogel and collagen microspheres integrated with extracellular matrix components were evaluated in the decrement of apoptosis in human pancreatic islets. MATERIALS/METHODS: For three-dimensional culture, the islets were encapsulated in collagen microspheres, containing laminin and collagen IV and embedded in alginate scaffold for one week. After that the islets were examined in terms of viability, apoptosis, genes and proteins expression including BAX, BCL2, active caspase-3, and insulin. Moreover, the islets function was evaluated through glucose-induced insulin and C-peptide secretion assay. In order to evaluate the structure of the scaffolds and the morphology of the pancreatic islets in three-dimensional microenvironments, we performed scanning electron microscopy. RESULTS: Our findings showed that the designed hydrogel scaffolds significantly improved the islets viability using the reduction of activated caspase-3 and TUNEL positive cells. CONCLUSIONS: The reconstruction of the destructed matrix with alginate hydrogels and collagen microspheres might be an effective step to promote the culture of the islets.

ABSTRACT

BACKGROUND: The liver transplant recipients are often subjected to excessive therapy by immunosuppressive drugs which produce several complications. Consequently, the minimization or even withdrawal of immunosuppression in selected patients is an attractive alternative. We investigated the frequency and characteristics of these near (or prope from Latin) tolerance in liver transplant recipients in Shiraz Organ Transplant Center. MATERIAL AND METHODS: We reviewed the medical records of over 3800 adult liver transplant recipients to select a group treated with a low-dose tacrolimus monotherapy (n = 90) between 1994 and 2017 in our transplant center. The patients with the best liver function parameters were selected; then, the clinician arbitrarily decided to withdraw steroids first and then mycophenolate mofetil and maintain each patient on a low dose tacrolimus. We compared the characteristics of prope tolerant recipients on a low-dose tacrolimus with those on standard immunosuppression, namely full-dose tacrolimus plus steroids and mycophenolate mofetil (n = 233). Data were analyzed by t-test, chi-square test using SPSS software version 16. RESULTS: Out of over 3800 liver transplant patients, 90 (2.34%) recipients were treated with a minimum dose of tacrolimus monotherapy. These recipients were compared to a selected group of 233 (6.1%) recipients treated with full-dose tacrolimus plus steroids and mycophenolate mofetil. In a prope tolerant group, there were 55 males (61.1%) and 35 females (38.9%) recipients. Mean age at the time of transplant was 39.92 ± (SD = 13.40) years with an average time from the transplantation time to completed weaning from triple immunosuppression to low-dose monotherapy of 41.35 months (SD = 17.27). The most common etiology of liver disease among both groups was viral hepatitis. CONCLUSION: The achievement of prope (almost) immune tolerance was possible only in some liver transplant recipients with a relatively low risk of rejection. Our analysis suggests that there is a difference in the underlying diseases and recipients' age and the number of rejections between the two groups.

ABSTRACT

AIM: This study investigated the safety and efficacy of tenofovir disoproxil fumarate (TDF) compared with lamivudine (LAM) in the prevention of recurrent HBV infection after liver transplantation (LT). BACKGROUND: Although the recurrence of hepatitis B virus after liver transplantation (LT) is now very uncommon with both nucleoside and nucleotide analogs represented with lamivudine and tenofovir disoproxil fumarate, respectively, few studies have compared the two classes. METHODS: A total of 302 HBV-related post-transplant patients who received liver transplants from deceased donors were enrolled in this retrospective study from 2011 to 2015 in the Shiraz Organ Transplant Center, Iran. The demographic data, kidney function, recurrence, resistance rate, and acute rejections at 1-, 6-, and 12-month intervals and after 12 months were compared on TDF (n=209) and lamivudine (n=93) groups. RESULTS: During a median follow-up period of 42.9 months, mean creatinine level was not significantly different between the two groups. Hepatitis B virus recurrence rate as well as acute graft rejection episode had no statistical difference in either group over the study period. CONCLUSION: Kidney function, creatinine level, disease recurrence, and acute graft rejection were comparable between tenofovir disoproxil fumarate and lamivudine in patients who received follow-up periods.

ABSTRACT

OBJECTIVES: Liver transplant recipients are more susceptible to vancomycin-resistant enterococci colonization than healthy individuals. We investigated the prevalence of vancomycin-resistant enterococci colonization and its effect on the outcomes of liver transplant recipients. MATERIALS AND METHODS: Patients who had undergone primary liver transplant at the Shiraz Organ Transplant Center from 2015 to 2017 were enrolled in this study. Demographic characteristics, laboratory test results, duration of stay in the intensive care unit, total duration of hospital stay, and clinical outcome data were extracted from the Shiraz Organ Transplant Center database. Posttransplant outcomes such as graft rejection, mortality, hospital stay, and kidney function tests were included for the first 90 days after transplant. RESULTS: A total of 753 liver transplant recipients (470 males and 283 females) were included in this study. Vancomycin-resistant enterococci colonization was identified in 51 patients (6.8%) after transplant at the time of intensive care unit admission. Our study found no significant difference between outcomes for patients with vancomycin-resistant enterococci colonization and outcomes for patients without colonization, including graft rejection, mortality, hospital stay, and kidney function tests. CONCLUSIONS: Our study revealed that asymptomatic vancomycin-resistant enterococci colonization in liver transplant patients has no adverse effect on the duration of posttransplant hospital stay, early mortality rate, graft rejection rate, or kidney function compared with noncolonized patients.

ABSTRACT

OBJECTIVES: We aimed to determine outcomes and predictors of intraoperative-detected portal vein thrombosis in liver transplant recipients. MATERIALS AND METHODS: We retrospectively analyzed 806 adult liver transplant recipients from Shiraz, Iran, to determine those with intraoperative-detected portal vein thrombosis. Patients with this complication were compared with age- and sex-matched patients without this complication. Background diseases, surgery parameters, hospital admission, reoperation, rethrombosis, acute rejection, and use of antico-agulants were assessed. Cox proportional hazards, logistic regression, and random classification forest and random survival forest plots were used for data analyses. RESULTS: Mean age of patients was 44.7 ± 13.2 years. Patients with intraoperative-detected portal vein thrombosis (n = 91; 11.3%) had mortality ratio of 2.9 (range, 1.0-8.6) and 2-year survival of 78% versus 2-year survival rate of 92% in patients without this disease. Median time of survival in patients with this complication who died was 2 weeks versus 10 months in patients who died and did not have this complication. Random classification forest plots showed that high fasting blood sugar, autoimmune hepatitis, low prothrombin time, and cryptogenic cirrhosis were (in order) the main predictors of this complication. Random survival forest plots revealed that low prothrombin time, having intraoperative-detected portal vein thrombosis, Model for End Stage Liver Disease score, primary sclerosing cholangitis, diabetes mellitus, and hepatocellular carcinoma were (in order) the main predictors of death in liver transplant recipients. Low body mass index was associated with mortality in patients with intraoperative-detected portal vein thrombosis (by Cox proportional hazards). CONCLUSIONS: One of every 9 liver transplant patients had intraoperative-detected portal vein thrombosis. Hazard of death was 2.9, and death occurred far earlier in patients with this complication. Improvements in diabetes mellitus care, prothrombin time, Model for End-Stage Liver Disease score, and body mass index may improve outcomes of these patients.

ABSTRACT

BACKGROUND: COVID-19 has been spreading worldwide with a significant death toll. Solid-organ transplantation (SOT) recipients are at higher risk due to their suppressed immune system. In this study, we aimed to conduct a systematic review on COVID-19 clinical manifestations and treatment strategies in SOT recipients. METHODS: We searched three databases for relevant terms related to COVID-19 and transplantation. 50 studies, including 337 patients, were reviewed. RESULTS: Two hundred thirty six patients were male, with a mean age of 49.9 years. The most prevalent group was the kidney 57.0%, followed by 17.2% heart and 13.6% liver. Fever and cough were the most reported clinical presentations. Infiltration (55.4%) in chest x-ray and ground-glass opacity (67.1%) in CT scans were the most radiological findings. It was found that 96.8% and 72.4% of patients present with CRP level and lymphocytopenia, respectively, and 70.6% of kidney recipients patients presented with high creatinine levels. The most common baseline immunosuppressants were calcineurin inhibitors (88.9%) and antimetabolites (73.2%). Antimetabolites (84.3%) and calcineurin inhibitors (54.3%) were discontinued/decreased 84.3% whereas glucocorticoids dosage almost has no change (77.9%) or even increased. 18.4% of cases had died, and 65.9% were discharged. CONCLUSIONS: Patients' demographics, signs, symptoms, and radiographic findings in SOT recipients are almost similar to the general population. However, gastrointestinal symptoms appear to be more common. There are different treatment strategies, but in most of them, antimetabolite and calcineurin inhibitors were decreased or discontinued, while corticosteroids were increased. Finally, COVID-19 seems to be more severe and has higher mortality in SOT recipients compared to the general population.
