RESUMO

Patients with neuroendocrine tumors with unresec-table liver involvement can benefit from liver transplant. There is a specific set of guidelines for neuroendocrine tumors with liver metastasis that involve less than 50% of the liver. However, beyond those guidelines, there are reports of exceptional criteria patients who benefited from liver transplant. Here, we present 2 unusual cases of patients with exceptional circumstances and with neuroendocrine tumors who underwent liver transplant. The first case describes a patient with an extremely rare neuroen-docrine tumor of the proximal common bile duct that caused liver biliary cirrhosis. The patient underwent tumor resection and liver transplant concurrently. The second case describes a patient with a neuroendocrine tumor of unknown primary origin with more than 50% hepatic involvement who received a liver transplant after downstaging. In our center, patients with unresectable hepatic metastases from neuroendoc-rine tumors are currently selected for liver transplant based on well-established criteria. However, these 2 cases did not meet the criteria for consideration of liver transplant; thus, multidisciplinary team sessions were held to discuss these 2 cases. After a period of nonsurgical treatment and evaluation of the tumor behavior, we selected the patients as candidates for liver transplant based on the favorable tumor behavior and favorable response to treatment. For both patients, we did not observe any signs of tumor recurrence during follow-up. The outcomes were acceptable, and the patients tolerated treatment well. Considering the favorable tumor pathology (G1 phase and low Ki67 index), we suggest that more studies should be conducted to evaluate the outcomes of patients with low-grade tumors and that the criteria for patients with low-grade tumors could be extended based on such future data.

RESUMO

Objective: The analysis of the gene expression of peripheral blood mononuclear cells (PBMCs) is important to clarify the pathogenesis of hepatocellular carcinoma (HCC) and the detection of suitable biomarkers. The purpose of this investigation was to use RNA-sequencing to screen the appropriate differentially expressed genes (DEGs) in the PBMCs for the HCC. Methods: The comprehensive transcriptome of extracted RNA of PBMC (n = 20) from patients with chronic hepatitis B (CHB), liver cirrhosis, and early stage of HCC (5 samples per group) was carried out using RNA-sequencing. All raw RNA-sequencing data analyses were performed using conventional RNA-sequencing analysis tools. Next, gene ontology (GO) analyses were carried out to elucidate the biological processes of DEGs. Finally, relative transcript abundance of selected DEGs was verified using qRT-PCR on additional validation groups. Results: Specifically, 13, 1262, and 1450 DEGs were identified for CHB, liver cirrhosis, and HCC, when compared with the healthy controls. GO enrichment analysis indicated that HCC is closely related to the immune response. Seven DEGs (TYMP, TYROBP, CD14, TGFBI, LILRA2, GNLY, and GZMB) were common to HCC, cirrhosis, and CHB when compared to healthy controls. The data revealed that the expressions of these 7 DEGs were consistent with those from the RNA-sequencing results. Also, the expressions of 7 representative genes that had higher sensitivity were obtained by receiver operating characteristic analysis, which indicated their important diagnostic accuracy for HBV-HCC. Conclusion: This study provides us with new horizons into the biological process and potential prospective clinical diagnosis and prognosis of HCC in the near future.

RESUMO

BACKGROUND: Interaction between immune modulators and inflammatory factors is considered as one of the main underlying pathologies of non-alcoholic fatty liver disease (NAFLD). Hence we aimed to assess the association between these cytokines and melatonin. METHODS: We enrolled adult patients diagnosed with fatty liver by ultrasonography in a crosssectional study. All of them underwent Fibroscan evaluation. The subjects who met the inclusion and exclusion criteria for NAFLD were involved. A normal group who did not have NAFLD, viral or non-viral hepatitis, and without a history of pancreatobiliary surgery, bariatric surgery, and intake of any medication that influence the liver was also selected. The participants were categorized into the three following groups: 1) fibrosis>9.1 kPa and steatosis>290 dbm, 2) fibrosis: 6-9.0 kPa and steatosis 240-290 dbm, and 3) normal group with fibrosis<6.0 kPa and steatosis<240 dbm. Laboratory assessment and a questionnaire including demographic, anthropometric, laboratories, and clinical data were completed for each of them. RESULTS: Totally 97 subjects were enrolled in the present study. The mean age of the subjects was 42.2±11.3 years. 60% of them (59 patients) were female. Serum levels of melatonin, interleukin (IL)-1B, IL-18, and IL-33 increased according to the advancing of NAFLD state. Based on multiple linear regression model, melatonin was significantly associated with IL-1B (ß=2.8, P<0.001,95% CI=1.41-4.19), IL-18 (ß=0.018, P=0.0005, 95% CI=0.006-0.03), and IL-33 (ß=0.31, P=0.045, 95% CI=0.008-0.62) after adjustment for other variables. CONCLUSION: Melatonin level has a strong association with these cytokines. This linkage probably influences on the development and progression of NAFLD. Therefore it can be hypothesized that the therapeutic approach that affects this process may have a significant impact.

RESUMO

Antibody-mediated rejection is a rare complication following liver transplantation, and there is a lack of a comprehensive treatment strategy to provide detailed information about the dose and duration of antibody-mediated rejection treatment. This study describes 8 adult liver transplantation recipients who developed antibody-mediated rejection between 2002 and 2021 in our center, as well as a review of the literature on the reported cases of antibody-mediated rejection in liver transplantation recipients. Our center's medical records were reviewed retrospectively to extract the necessary data on patients' characteristics, management, and outcomes. Then, a comprehensive search using Embase, PubMed, Web of Science, Cochrane Library, and Google Scholar databases was conducted without time limitation until June 2021. Finally, a stepwise protocol was developed for managing acute, chronic, and recurrent antibody-mediated rejection in patients undergoing liver transplantation, based on our own experience, reported cases in the literature, and data from kidney transplantation. By review of the literature, 24 case studies containing 64 patients were identified, and their management strategies and outcomes were evaluated. Although various combinations of corticosteroids, plasma exchange, intravenous immunoglobulin, and biological agents are used in the treatment of acute antibody-mediated rejection in liver transplantation, treatment strategies should be classified according to the type, severity, and the timing of its onset. Given the importance of early treatment, rituximab and/or bortezomib should be started as soon as possible if no improvement in liver enzymes/bilirubin is observed during the initial treatment strategy using corticosteroids, plasma exchange, and intravenous immunoglobulin.

RESUMO

AIM: The associations between serum levels of melatonin and concentrations of tumor necrosis factor (TNF)-a and interleukin (IL)-6 were assessed among patients with different degrees of non-alcoholic fatty liver disease. BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) has become a very common worldwide disease. METHODS: In this cross-sectional study, adult patients diagnosed with fatty liver disease by Fibroscan evaluation were included if they met the inclusion/exclusion criteria for NAFLD. The participants were categorized into the three following groups: 1) fibrosis> 9.1KP and steatosis >290 dbm; 2) fibrosis: 6-9.0 KP and steatosis 240-285; and 3) fibrosis < 5.8 KP and steatosis<240 dbm. Post-fasting, 5 ml of venous blood was collected for laboratory assessment, and a questionnaire including demographic, anthropometric, laboratories and clinical data was completed. RESULTS: A total of 97 participants were included. The mean age was 42.21±11 years, and 59 patients (60.0%) were female. Melatonin levels as well as pro-inflammatory cytokines levels were correlated with advancing fibrosis and steatosis in univariate analysis. A significant association was observed between these cytokines and advancing fibrosis, severe steatosis levels, and melatonin concentrations. Furthermore, in the multiple linear regression model, melatonin levels showed a significant association with these cytokines. CONCLUSION: Melatonin may have protective effects on tissue injury during advancing liver fibrosis via cytokines modulation. Therefore, it can be considered as a potential therapeutic management strategy for NAFLD.

RESUMO

The present COVID-19 pandemic is a cause for concern among solid-organ transplant recipients, who are generally at high risk for infection and for whom infection with COVID-19 carries additional risks for complications and mortality that are higher than the COVID-19-associated risks for the general population. We report the case of a liver transplant recipient who presented with COVID-19 and multiple complications. A 39-year-old woman with a liver transplant was diagnosed with COVID-19 within the first week after transplant surgery. Mycophenolate was withheld, and interferon ß was administered for management of COVID-19. She developed thrombotic thrombocytopenic purpura, acute antibody-mediated rejection, and posterior reversible leukoencephalopathy syndrome during hospitalization. All of these complications may be related to COVID-19 or its management modalities. We considered 3 possible causes for thrombotic thrombocytopenic purpura in this patient: the COVID-19 infection itself, immunosuppression treatment with cyclosporine, and treatment with interferon ß. Immunosuppression reduction and interferon treatment may result in antibody-mediated rejection. COVID-19, thrombotic thrombocytopenic purpura, and cyclosporine may play a combined role in the development of posterior reversible leukoencephalopathy syndrome. In conclusion, thrombotic thrombocytopenic purpura, antibody-mediated rejection, and posterior reversible leukoencephalopathy syndrome may represent a continuum of 3 thrombotic microangiopathy conditions fostered by interplay between the COVID-19 infection and the treatment modalities for COVID-19 management in this patient.

RESUMO

BACKGROUND Inflammation has a significant impact on the development and progression of fatty liver diseases.In this study, we aimed to investigate the relation between serum levels of nuclear factor kappa B (NFkB) and Forkhead box protein P3 (FOXP3)with fibrosis severity among patients with non-alcoholic fatty liver disease(NAFLD). METHODS In a prospective study, the patients suspicios of havingfatty liver were enrolled. The exclusion criteria lack of viral hepatitis, autoimmune hepatitis, Wilson's or other known liver diseases,history of liver or biliary surgery,bariatric surgery, and medications that influence liver metabolism. The participantsunderwent liver fibroscan. According to liver fibrosis, the patients weredivided into two groups; 1)fibrosis less than 7.2 KP,2)advanced NAFLD, fibrosis ≥7.3 KP. A10 cc fasting blood sample was taken from each patient for laboratory assessments.The variables between the two groups were compared using Chi-square or Fisher's exact test.The independence of cytokines was assessed by a logistic regression test. RESULTS Totally 90 patients were enrolled.The mean age was 42.21 ± 11 years. Of them, 50 and 47 participants were allocated to groups 1 and 2, respectively. In the univariate analysis, we revealed asignificant difference between age, body mass index (BMI), fasting blood glucose, liver enzymes, total cholesterol, andtriglyceride levels. Also, there was a significant difference betweenthe levels of NFKB and FOXP3 in group one compared with group two of the participants,as FOXP3(9.17 ± 10.0 vs. 18.63 ± 12.9; p < 0.001) and NFKB (1.70 ± 1.70; p < 0.01). After excluding the confounding factors, we observed a significant association between fibrosis level and cytokine levels in logistic regression. CONCLUSION Serum levels of NFKB and FOXP3 increased by advancing liver fibrosis in patients with NAFLD.This is an independent association. The identification of intermediary regulatory factors would be necessary.

RESUMO

BACKGROUND: We studied the clinical characteristics and outcomes of 905 hospitalized coronavirus disease 2019 (COVID-19) patients admitted to Imam Khomeini Hospital Complex (IKHC), Tehran, Iran. METHODS: COVID-19 patients were recruited based on clinical symptoms and patterns of computed tomography (CT) imaging between February 20 and March 19. All patients were tested for the presence of COVID-19 RNA. The Poisson regression model estimated the incidence rate ratio (IRR) for different parameters. RESULTS: The average age (± standard deviation) was 56.9 (±15.7) years and 61.77% were male. The most common symptoms were fever (93.59%), dry cough (79.78%), and dyspnea (75.69%). Only 43.76% of patients were positive for the RT-PCR COVID-19 test. Prevalence of lymphopenia was 42.9% and more than 90% had elevated lactate dehydrogenase (LDH) or C-reactive protein (CRP). About 11% were severe cases, and 13.7% died in the hospital. The median length of stay (LOS) was 3 days. We found higher risks of mortality in patients who were older than 70 years (IRR = 11.77, 95% CI 3.63-38.18), underwent mechanical ventilation (IRR = 7.36, 95% CI 5.06-10.7), were admitted to the intensive care unit (ICU) (IRR = 5.47, 95% CI 4.00-8.38), tested positive on the COVID-19 test (IRR = 2.80, 95% CI 1.64-3.55), and reported a history of comorbidity (IRR = 1.76, 95% CI 1.07-2.89) compared to their corresponding reference groups. Hydroxychloroquine therapy was not associated with mortality in our study. CONCLUSION: Older age, experiencing a severe form of the disease, and having a comorbidity were the most important prognostic factors for COVID-19 infection. Larger studies are needed to perform further subgroup analyses and verify high-risk groups.

RESUMO

The coronavirus associated disease 2019 (COVID-19) caused by the SARS-CoV-2 virus has rapidly spread all around the world and became pandemic in March 2020. Data on liver transplantation and chronic liver disease during the pandemic has remained scarce, and there is little information on whether immunosuppressed patients are at higher risk of developing severe COVID-19 infection. This review provides information for health care providers who care for patients with liver transplantation and chronic liver diseases.

RESUMO

Acute Liver failure (ALF) is a life-threatening disease and is determined by coagulopathy (with INR ≥ 1.5) and hepatic encephalopathy as a result of severe liver injury in patients without preexisting liver disease. Since there are problems with liver transplantation including lack of donors, use of immunosuppressive drugs, and high costs of this process, new therapeutic approaches alongside current treatments are needed. The placenta is a tissue that is normally discarded after childbirth. On the other hand, human placenta is a rich source of mesenchymal stem cells (MSCs), which is easily available, without moral problems, and its derived cells are less affected by age and environmental factors. Therefore, placenta-derived mesenchymal stem cells (PD-MSCs) can be considered as an allogeneic source for liver disease. Considering the studies on MSCs and their effects on various diseases, it can be stated that MSCs are among the most important agents to be used for novel future therapies of liver diseases. In this paper, we will investigate the effects of mesenchymal stem cells through migration and immigration to the site of injury, cell-to-cell contact, immunomodulatory effects, and secretory factors in ALF.

RESUMO

OBJECTIVES: Orthotopic liver transplant can be accompanied by an obscure bleeding pattern in patients with severe hepatic malfunction. In the present study, coagulation conditions of patients with cirrhosis of the liver due to primary sclerosing cholangitis and nonbiliary causes of cirrhosis were compared using rotational thromboelastometry assays obtained before orthotopic liver transplant. MATERIALS AND METHODS: This case control study analyzed patients who were candidates for orthotopic liver transplant from 2010 to 2016. Eighty patients with cirrhosis of the liver (40 patients with primary sclerosing cholangitis and 40 with nonbiliary causes of cirrhosis) were randomly selected and enrolled into the study. Patients received rotational thromboelastometry assays under anesthesia just before the start of the operation, and results were compared between the 2 patient groups. RESULTS: Of 80 patients, 52 were men and 28 were women. In the assays, we found that maximum amplitudes in 10 and in 20 minutes and maximum clot firmness parameters were higher in patients with primary sclerosing cholangitis. The alpha angle and clot formation time were different in the intrinsic and extrinsic assay panels. In the intrinsic assay, we found clotting time to be shorter (P < .05). The average of all parameters in all 3 assays (intrinsic, extrinsic, and fibrinogen contribution) was lower in patients with nonbiliary causes of cirrhosis than in those with primary sclerosing cholangitis. CONCLUSIONS: In contrast with previous studies that found that patients with primary sclerosing cholangitis are hypercoagulable, our study observed that they have normal coagulable results. Furthermore, we found that, although mean coagulation indexes in patients with primary sclerosing cholangitis were within normal ranges, in patients with nonbiliary causes of cirrhosis, these indexes were generally lower.

RESUMO

Primary graft dysfunction (PGD) and non-function (PNF) happen in 8.7-24.7% and 0.9-7.2% of liver transplant recipients, respectively. These phenomena increase treatment cost and patients' death. This study assessed the effect of L-carnitine supplementation on the incidences of PNF/PGD in liver transplant recipients. This randomized, placebo-controlled, clinical trial was performed on adult liver transplant recipients. Patients took L-carnitine syrup 500 mg three times daily or placebo from the time of including in transplant waiting list until the day of transplant surgery (median 14 days, 1-192 days). Thirty-three patients in L-carnitine and 39 patients in placebo group completed the study. Although not statistically significant, PNF and PGD happened less frequently among recipients in L-carnitine compared with placebo group (3% vs. 12.8% for PNF; 15.2% vs. 30.8% for PGD). Alanine aminotransferase (ALT) and aspartate aminotransferase were lower in L-carnitine group at day 3 after transplantation. ALT declined more significantly within 48 h after transplantation in L-carnitine arm (median 120.50 vs. 79 IU/L; P = 0.03). One-month patients' survival was significantly higher in L-carnitine versus placebo group (97% vs. 74.4%; P = 0.008). The rates of PNF and PGD in L-carnitine group were approximately one-fourth and one-half of placebo group respectively. One-month patients' survival was higher in L-carnitine group.

RESUMO

BACKGROUND: Iran's experience with liver transplantation (LT) began more than two decades ago. The purpose of this article is to present the status of LT in Iran, review specific characteristics of the programs, their outcomes, and their growth to become one of the largest LT programs in the world. METHODS: A questionnaire, asking for data on the number of transplants performed and specifics of the recipients and type of donors with focus on indications and outcomes was sent to LT programs. RESULTS: During a period of 23 years, 4,485 LTs were performed at 6 centers in the country. Of these, 4106 were from deceased donors and 379 were from living donors. There were 3553 adults and 932 pediatric recipients. Hepatitis B and biliary atresia were the most common etiologies in adult and pediatric patients, respectively. Overall survival rates at 1, 5, and 10 years were 85%, 77%, and 71% for adults and 76%, 67% and 56% for pediatric patients, respectively. CONCLUSION: Approval of the brain death law in Iran and coordinated efforts by the transplant centers to build comprehensive LT programs has resulted in the ability to procure more than 700 deceased donors per year with acceptable long-term survival.

RESUMO

INTRODUCTION: There was no report of nephrotoxicity during clinical trials assessed sofosbuvir for treatment of hepatitis C (HCV) infection. This may be due to excluding patients with severe kidney dysfunction, as a main population at risk for drug-induced nephrotoxicity from these studies. There are some reports of acute kidney injury (AKI) possibly related to sofosbuvir-containing treatments from real-life experiences. Areas covered: Available data on epidemiology, type, and possible risk factors for nephrotoxicity of sofosbuvir-containing treatment are reviewed. Related articles were collected by searching Scopus, Pubmed, and Science direct. Search terms were 'sofosbuvir', 'nephrotoxicity', 'acute kidney injury', 'renal impairment', and "direct acting antiviral agents. Expert commentary: AKI may happen in 1-15% of patients who are treated with sofosbuvir-containing regimens. Compared with patients with normal kidney function, higher incidences of AKI have been reported in patients with baseline moderate to severe kidney dysfunction. Median time to AKI is 9 weeks after starting sofosbuvir. Baseline renal impairment, presence of ascites, diabetes or concomitant use of nephrotoxic drugs are possible risk factors for sofosbuvir-induced AKI. AKI following sofosbuvir-containing treatment is characterized by histological feature of acute interstitial nephritis and may be reversible following drug discontinuation. Monitoring of kidney function is recommended in sofosbuvir-treated patients.

RESUMO

BACKGROUND: Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal complaints. GERD, caused by the reflux of stomach contents into the esophagus, leads to troublesome symptoms such as heartburn and regurgitation. It is classified into two types: erosive esophagitis, characterized by visible esophageal mucosa erosion in endoscopy, and non-erosive reflux disease (NERD). GERD is a chronic and recurrent disease that impairs the quality of life and imposes socioeconomic and therapeutic burdens to both patients and society. OBJECTIVE: Due to the failure of the conventional treatments for GERD and to the traditional use of Amla (Phyllanthus emblica L.), in addition to beneficial effects shown in recent studies, we evaluated the safety and efficacy of Amla tablet for improvement of symptoms of patients with NERD. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: We designed a double-arm, randomized, double-blind, placebo-controlled clinical trial. Sixty-eight patients who had classic symptoms of GERD (heartburn, regurgitation and epigastralgia) for at least three months before the start of the trial were randomized in two parallel groups. Patients in the Amla group received two 500 mg Amla tablets twice a day, after meals, for 4 weeks. In the control group, patients received placebo tablets similar to the Amla prescription. MAIN OUTCOME MEASURES: The patients were visited at baseline, and at the end of the 2nd and 4th weeks of intervention; their symptoms were measured on a frequency and severity scale for the symptoms of NERD, according to the quality of life in reflux-associated disease questionnaire. RESULTS: Frequencies of heartburn and regurgitation in both groups of the study were significantly reduced after intervention (P < 0.001). Repeated measures logistic regression analysis showed that, in the Amla group, there was a more significant reduction in regurgitation frequency, heartburn frequency, regurgitation severity and heartburn severity during the study period, compared with the placebo group (P < 0.001). CONCLUSION: This randomized double-blind, placebo-controlled clinical trial demonstrated that Amla could reduce frequencies of heartburn and regurgitation and improve heartburn and regurgitation severity in patients with NERD. TRIAL REGISTRATION: Iranian Registry of Clinical Trials IRCT2016061428469N1.

RESUMO

BACKGROUND AND AIM: Recent studies have suggested the therapeutic effect of antimicrobial agents on primary sclerosing cholangitis (PSC). Therefore, we aimed to evaluate the efficacy of oral vancomycin in patients with PSC. METHOD: A triple blinded, randomized, placebo-controlled trial was performed on 29 patients (2015-2016) in the Imam Khomeini Hospital, Tehran, Iran (NCT02605213). Patients were divided into two groups by simple randomization method: placebo 11 (37.9%)/vancomycin 18 (62.1%) and were treated with oral vancomycin (125 mg, four times a day) for 12 weeks. All patients in both groups simultaneously underwent treatment with ursodeoxycholic acid (UDCA, 300 mg, three times a day) before and during the study. Patients' laboratory data and clinical symptoms were recorded at the beginning, first and third month after starting treatment, and the response to treatment was analyzed. RESULTS: 29 patients with a mean age of 36.27+/-10.60 years were included in the study. Primary endpoints were accomplished in the vancomycin group showing a significant decline in the mean level of PSC Mayo risk score (decrease rate 3rd month - baseline = -322.03%, p=0.026) during follow up time. Moreover, the analysis of the level of alkaline phosphatase (ALP) in the vancomycin group showed a significant decrease in the third month of treatment as compared to its level in the first month (mean difference 3rd month -1st month = -142.92, Decrease rate= -18.24%, p=0.02). Among secondary endpoints, erythrocyte sedimentation rate (p=0.005), gamma-glutamyl transpeptidase (p=0.02) and patients' symptoms including fatigue, pruritus, diarrhea and anorexia showed a significant decrease in the vancomycin group. CONCLUSION: This study demonstrated an acceptable efficacy of vancomycin in the treatment of PSC.

RESUMO

CONTEXT: Bowel obstruction is one of the most common causes of acute abdomen. Because of heterogeneity of patients' population and variety of causes, therapeutic strategies are not standardized, so treatment of intestinal obstruction is a surgical challenge in many cases. A traditional medicine approach could help detect some issues that were ignored by modern medicine. One of the major schools of medicine, with a history of several thousand years, is Iranian traditional medicine. In this regard, Avicenna, who lived in the medieval period, has had a great influence on the medical knowledge of the world by writing an encyclopedia of medicine entitled "Qanun of Medicine." EVIDENCE ACQUISITION: The aim of this study was to investigate Avicenna's views on the causes of intestinal obstruction and comparing them to modern medicine views. This is a review study on an Iranian traditional textbook of medicine by Avicenna, entitled "Qanun of Medicine" (in short "Qanun"). We used Qanun in its original language (Arabic) along with its Persian translation. It consists of 5 books. Part 16 of the third book talks about intestinal anatomy and introduces some intestinal diseases such as "qoolinj" and "ilavos." Intestinal obstruction can be a kind of "qoolinj" or "ilavos" disease. All intestinal obstruction etiologies in Qanun are searched in international and Iranian databases (Scopus, ISI, SID, and Iranmedex) and similar causes in modern medicine will be discussed in this article. RESULTS: According to Qanun, 16 causes are involved in intestinal etiologies of bowel obstruction such as "reeh," mucoid phlegm, abdominal hot and dry distemperament, decreased bile secretion, job, and so on while modern medicine considers some of them, for instance, volvulus, intestinal herniation, worm, intestinal pseudo-obstruction, and opiate. CONCLUSIONS: Attention to the similar causes of intestinal obstruction in modern medicine and traditional medicine is the starting point for investigation of noninvasive diagnostic and therapeutic methods that have been mentioned in Qanun. In addition, etiologies which are missed in modern medicine can open new doors to the researchers and gastroenterologists for the study, diagnosis, and prevention of the disease.

RESUMO

Objectives. The study was aimed at providing a psychosocial profile for Iranian liver transplant candidates referred to an established liver transplantation program. Material and Methods. Patients assessed for liver transplant candidacy in Imam Khomeini Hospital (Tehran, Iran) between March 2013 and September 2014 were included. The following battery of tests were administered: Psychosocial Assessment of Candidates for Transplant (PACT), the Short-Form health survey (SF-36), and Hospital Anxiety and Depression Scale (HADS). Results. Psychosocial assessment in 205 liver transplant candidates revealed significant impairments in several SF-36 domains; social functioning was the least and physical functioning was the most impaired domains. The prevalence of cases with probable anxiety and depressive disorders, according to HADS, was 13.8% and 5.6%, respectively. According to PACT, 24.3% of the assessed individuals were considered good or excellent candidates. In 11.2%, transplantation seemed poor candidate due to at least one major psychosocial or lifestyle risk factor. Poor candidate quality was associated with impaired health-related quality of life and higher scores on anxiety and depression scales (p < 0.05). Conclusions. Transplant programs could implement specific intervention programs based on normative databases to address the psychosocial issues in patients in order to improve patient care, quality of life, and transplant outcomes.

RESUMO

Pseudoaneurysm happens when the artery wall is injured and the blood is contained by the surrounding tissues with eventual formation of a fibrous sac communicating with the artery. We report a case of a 39-year-old man with inferior epigastric artery (IEA) pseudoaneurysm after paracentesis. The pseudoaneurysm was diagnosed by Doppler ultrasound and treated by surgical intervention regarding the patient's underlying comorbidity. IEA false aneurysm must be included in the differential diagnosis during investigation of the cause of any swelling after paracentesis. Cirrhotic patients may be more prone to this complication because of thin rectus muscle that could not confine the hematoma.
