Abstract
Wilson's disease is a complicated medical condition caused by the accumulation of copper, mostly in the liver and brain. The genetic basis of Wilson's disease is attributed to the presence of pathogenic variants in the ATP7B copper-transporting gene, which prevents the excretion of copper through the biliary tract. To date, ATP7B remains the only identified gene that has been linked to the development of this disease. Our understanding of the disease has been associated with the identification of particular disease-causing variants that present specific impairments in copper transporters. It is crucial to identify the most frequent variant in terms of ethnicity to facilitate testing of its functionality. This study represents the initial comprehensive analysis of ATP7B variants, providing insights into the extensive range of disease-causing mutations. Here, we describe the 1275 distinct ATP7B variants documented so far, with particular emphasis on their regional and ethnic prevalence. The H1069Q missense variant is the most frequently reported in Europe, Northern America, and North Africa, whereas the R778L, C271*, and M645R variants are the most prevalent in the East Asian, Middle Eastern-South Asian, and South American populations, respectively. Acquiring such knowledge would facilitate the implementation of a selective mutation screening approach, targeting the most predominant variant identified within a specific ethnic group or geographic region for better diagnosis of the disease.

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
Nanotechnology seems to provide solutions to the unresolved complications in skin tissue engineering. According to the broad function of nanoparticles, this review article is intended to build a perspective for future success in skin tissue engineering. In the present review, recent studies were reviewed, and essential benefits and challenging issues regarding the application of nanoparticles in skin tissue engineering were summarized. Previous studies indicated that nanoparticles can play essential roles in the improvement of engineered skin. Bio-inspired design of an engineered skin structure first needs to understand the native tissue and mimic that in laboratory conditions. Moreover, a fundamental comprehension of the nanoparticles and their related effects on the final structure can guide researchers in recruiting appropriate nanoparticles. Attention to essential details, including the designation of nanoparticle type according to the scaffold, how to prepare the nanoparticles, and what concentration to use, is critical for the application of nanoparticles to become a reality. In conclusion, nanoparticles were applied to promote scaffold characteristics and angiogenesis, improve cell behavior, provide antimicrobial conditions, and cell tracking.

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.

Abstract
BACKGROUND Splenic cysts are quite rare and asymptomatic. They may result from infection by a parasite, especially Echinococcus granulosus (hydatid cyst), or from non-parasitic causes. Since primary splenic cysts are not common, simple cysts can be misdiagnosed with a hydatid cyst in endemic areas. CASE PRESENTATION We reported a 14-year-old Iranian girl initially presented with a vague abdominal pain, which progressed to left shoulder pain, fullness, early satiety, and shortness of breath and remained undiagnosed for 7 months despite seeking medical attention. Finally, imaging revealed a massive splenic cyst measuring 220 mm × 150 mm × 160 mm raising concern for a hydatid cyst due to regional endemicity. Consequently, the patient underwent total splenectomy. However, histopathological examination surprisingly revealed a simple non-parasitic cyst. CONCLUSIONS Detecting rare simple spleen cysts requires early ultrasonography (US) and careful reassessment of diagnoses for non-responsive or worsening symptoms. Distinguishing them from splenic hydatidosis, especially in endemic areas, demands thorough paraclinical evaluations and patient history regarding potential parasitic exposure. While total splenectomy is the primary treatment for these huge cysts, the optimal surgical approach should be tailored case by case. These insights emphasize a comprehensive diagnostic approach to enhance accuracy and optimize patient care for these uncommon cysts.

Abstract
BACKGROUND Teratoma is a type of germ cell tumor consisting of one or multiple tissues derived from germinal layers. The location and size of the tumor can cause various presentations. Here we report one of the largest ever cases of immature cystic teratoma. CASE PRESENTATION In this report, we presented a 24-year-old patient with dyspnea, chest pain, nausea, and anorexia. A computed tomography scan revealed a giant, right-sided mass measuring about 190 × 150 × 140 mm. Chemotherapy was initiated for the patient, followed by thoracotomy. Histopathological evaluation revealed the nature of the mass to be an immature mediastinal teratoma. CONCLUSION the incidence of immature mediastinal teratoma is uncommon, and due to its rarity, the diagnosis needs more profound evaluation studies such as radiological and pathological assessments. Immature teratomas are optimally treated by a combination of chemotherapy and complete resection.

Abstract
BACKGROUND Sclerosing angiomatoid nodular transformation of the spleen is a relatively rare benign vascular lesion in both adult and pediatric age groups with unclear etiopathogenesis and variable clinical presentations. Many benign and also malignant splenic masses could mimic sclerosing angiomatoid nodular transformation, both clinically and radiologically. Herein, we report our experience with a case of sclerosing angiomatoid nodular transformation in a 3-year-old girl. CASE REPORT A 3-year-old Iranian girl presented with abdominal pain, back pain, and constipation for 2 weeks. She was being followed up by a pediatrician due to her short stature and persistent anemia. Physical examination showed stable vital signs, short stature, pallor, and a puffy face. Laboratory evaluation showed normochromic normocytic anemia with a normal reticulocyte count, ferritin, and hemoglobin electrophoresis. Radiologic assessments revealed a hypoechoic lesion in the spleen with high vascularity, clinically suspected to be lymphoma. She was operated on, and after partial splenectomy, pathologic evaluation of the spleen showed a solitary, well-demarcated, and unencapsulated dark mass. Microscopic examination revealed micronodular appearance composed of irregular-shaped vascular spaces lined by plump endothelial cells and surrounded by concentric collagen fibers, features in keeping with sclerosing angiomatoid nodular transformation. The patient's anemia was resolved after surgery, and no clinical or radiologic deficits were noted during the 10-month follow-up visits. CONCLUSION Although sclerosing angiomatoid nodular transformation is exceedingly rare in children, it should be considered a differential diagnosis in pediatric splenic neoplasms with concurrent hematologic manifestations, such as anemia.

Abstract
BACKGROUND Posttransplant lymphoproliferative disorder is one of the most severe complications after transplantation, caused by uncontrolled proliferation of Epstein-Barr virus-positive B-cells in the setting of chronic immunosuppression. As one of the biggest transplant centers worldwide, we observed a potential increase in the number of patients with posttransplant lymphoproliferative disorder presenting with gastrointestinal symptoms in 1 year, during the coronavirus disease 2019 pandemic. There is limited information about dysregulation of the immune system following coronavirus disease 2019 infection, which may lead to Epstein-Barr virus reactivation in Epstein-Barr virus-positive B-cells and development of posttransplant lymphoproliferative disorder. Furthermore, there is no consensus in literature on a modality that can help in early diagnosis of posttransplant lymphoproliferative disorder with nonspecific gastrointestinal presentations before late and fatal complications occur. CASE PRESENTATION Our case series includes five Iranian (Persian) patients, three female (2, 2.5, and 5 years old) and two male (2 and 2.5 years old), who developed gastrointestinal posttransplant lymphoproliferative disorder after liver transplantation. All of our patients were on a similar immunosuppressant regimen and had similar Epstein-Barr virus serologic status (seronegative at time of transplantation but seropositive at time of posttransplant lymphoproliferative disorder diagnosis). Four patients had either a positive coronavirus disease 2019 polymerase chain reaction test or exposure within the family. Although all of our patients presented with nonspecific gastrointestinal symptoms, four patients developed late posttransplant lymphoproliferative disorder complications such as bowel perforation and obstruction. All five patients with gastrointestinal posttransplant lymphoproliferative disorder received chemotherapy, but only two survived and currently are continuing the therapy. In one of the surviving patients, prompt endoscopic investigation resulted in early diagnosis of posttransplant lymphoproliferative disorder and a better outcome. CONCLUSION Since 80% of our patients had exposure to coronavirus, a potential relationship might be suggested between the two. Furthermore, as we witnessed in one case, urgent endoscopic investigation in immunocompromised patients presenting with gastrointestinal symptoms can improve the clinical outcomes and therefore should be considered for early diagnosis of posttransplant lymphoproliferative disorder.

Abstract
BACKGROUND There exists strong evidence that human papillomavirus (HPV) is associated with cervical cancer (CC). HPV E6 is a major oncogene whose sequence variations may be associated with the development of CC. There is not sufficient data on the distribution of HPV types in ThinPrep cytology specimens and HPV 16/18 E6 gene variations among CC patients in the southwest of Iran. This study was conducted to contribute to HPV screening and vaccination in Iran. METHODS A total of 648 women screened for cervicitis, intraepithelial neoplasia or CC were included in the study. All participants underwent ThinPrep cytology testing, single-step HPV DNA detection and allele-specific reverse hybridization assays. Moreover, a total of 96 specimens previously tested positive for single infection with HPV16 or 18 were included for variant analysis. HPV16/18 lineages and sublineages were determined by PCR assays followed by sequencing the E6 gene and the construction of neighbor-joining phylogenetic trees. RESULTS Overall, HPV DNA was detected in 62.19% of all the screened subjects. The detection rates of HPV DNA among individuals with normal, ASC-US, ASC-H, LSIL, and HSIL cervical cytology were 48.9%, 93.6%, 100%, 100%, and 100%, respectively. Low-risk HPVs were detected more frequently (46.9%) than high-risk (38.9%) and possible high-risk types (11.1%). Of 403 HPV-positive subjects, 172 (42.7%) had single HPV infections while the remaining 231 (57.3%) were infected with multiple types of HPV. Our results indicated a remarkable growth of high-risk HPV66 and 68 and low-risk HPV81 which have rarely been reported in Iran and HPV90 and 87 that are reported for the first time in the country. In addition, 3 lineages (A, D, and C) and 6 sublineages (A1, A2, A4, C1, D1, and D2) of HPV16, and one lineage and 4 sublineages (A1, A3, A4, and A5) of HPV18 were identified. The studied HPV16 and 18 variants mainly belonged to the D1 and A4 sublineages, respectively. CONCLUSION The present study suggests that the prevalence of HPV infection in women of all age groups with or without premalignant lesions in the southwestern Iran is high and the predominant HPV types in the southwest of Iran may differ from those detected in other parts of the country. This study also highlights the necessity of not only initiating HPV vaccination for the general population but also developing new vaccines that confer immunity against the prevalent HPV types in the area and national cervical screening programs using a combination of thinPrep cytology test and HPV detection assays in order to improve the accuracy of the screening.

Abstract
BACKGROUND The immunity of CD4+ T cell subsets against human cytomegalovirus (HCMV) is considerable due to their essential role in controlling the infection in transplant individuals. Previously explained CD4+ subsets such as T helper (Th) 1 have been proven to have a protective role against HCMV infection, while the role of the recently identified Th22 subset has not been described yet. Here, the frequency changes of Th22 cells and the IL-22 cytokine production were investigated in kidney transplant recipients with and without HCMV infection. METHODS Twenty kidney transplant patients and ten healthy controls were enrolled in this study. Patients were categorized into HCMV + and HCMV- groups based on the HCMV DNA real-time PCR results. After isolating CD4+ T cells from PBMCs, the phenotype (CCR6+CCR4+CCR10+) and cytokine profile (IFN-γ-IL-17-IL-22+) of Th22 cells were analyzed by flow cytometry. The gene expression of Aryl Hydrocarbon Receptor (AHR) transcription factor was analyzed by real-time PCR. RESULTS The phenotype frequency of these cells was lower in recipients with infection than in those without infection and healthy controls (1.88 ± 0.51 vs. 4.31 ± 1.05; P = 0.03 and 4.22 ± 0.72; P = 0.01, respectively). A lower Th22 cytokine profile was observed in patients with infection than in the two other groups (0.18 ± 0.03 vs. 0.20 ± 0.03; P = 0.96 and 0.33 ± 0.05; P = 0.04, respectively). AHR expression was also lower in patients with active infection. CONCLUSIONS Overall, this study for the first time suggests that the reduced levels of Th22 subset and IL-22 cytokine in patients with active HCMV infection might indicate the protective role of these cells against HCMV.

Abstract
Angiogenesis is a vital step in tissue regeneration. Hence, the current study aimed to prepare oxidized dextran (Odex)/collagen (Col)-hydrogels with laminin (LMN), as an angiogenic extracellular matrix (ECM) component, for promoting human umbilical vein endothelial cell (HUVEC) proliferation and function. Odex/Col scaffolds were constructed at various concentrations and temperatures. Using oscillatory rheometry, scanning electron microscopy (SEM), and cell viability testing, the scaffolds were characterized, and then HUVEC proliferation and function was compared with or without LMN. The gelation time could be modified by altering the Odex/Col mass ratio as well as the temperature. SEM showed that Odex/Col hydrogels had a more regular three-dimensional (3D) porous structure than the Col hydrogels. Moreover, HUVECs grew faster in the Col scaffold (12 mg/mL), whereas the Odex (30 mg/mL)/Col (6 mg/mL) scaffold exhibited the lowest apoptosis index. Furthermore, the expression level of vascular endothelial growth factor (VEGF) mRNA in the group without LMN was higher than that with LMN, and the Odex (30 mg/mL)/Col (6 mg/mL) scaffold without LMN had the highest VEGF protein secretion, allowing the cells to survive and function effectively. Odex/Col scaffolds, with or without LMN, are proposed as a tissue engineering construct to improve HUVEC survival and function for angiogenesis.

Abstract
We reported two patients, a 45-year-old lady and a 48-year-old man, known cases of untreated liver and lung hydatid cysts complicated with bronchobiliary fistulae. Surgery was performed, and bronchobiliary fistulae were diagnosed intraoperatively. Lobectomy was done on the lobe, which was chronically infected. Symptoms resolved after surgery in both cases. Green-colored sputum in a patient with a history of echinococcosis should raise the physician's attention to the probability of a connection between the bronchial tree and the biliary tract. Surgery in advanced cases is a suitable therapeutic option.

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
OBJECTIVES Hereditary fructose intolerance (HFI) is caused by aldolase B enzyme deficiency. There has been no report about HFI from Iran and the type of mutations has not been reported in the Iranian population so far. CASE PRESENTATION Herein we report a 2 year old girl presented with failure to thrive, hepatomegaly, and liver dysfunction. The primary impression has been hepatic glycogen storage disease type 1 or 6. This diagnosis was not confirmed by laboratory data and liver biopsy. Therefore, targeted-gene sequencing (TGS) covering 450 genes involved in inborn errors in metabolic diseases was performed. The results of TGS showed a rare novel homozygous pathogenic variant c.944del (p.Gly315ValfsTer15) in the ALDOB gene. CONCLUSIONS This report introduces a novel variant that expands the mutational spectrum of the ALDOB gene in patients with HFI.

Abstract
INTRODUCTION Liver transplantation (LT) is the choice of therapeutic option for end-stage hepatic GSD patients; however, reports about the long-term outcome of LT in these patients have remained controversial. METHODS We performed a systematic review and meta-analysis of observational studies published until Dec 31, 2021, that investigated the long-term outcome of LT in hepatic GSD patients. A literature search in the MEDLINE/PubMed, EMBASE,Cochrane Library, Scopus and Web of Science Core Collection databases was performed. RESULTS 14 studies with 210 patients were included in our analysis. As the results showed, the pooled proportion of GSD patients with complications after liver transplant (e.g., hemorrhagic shock, biliary complications, tacrolimus encephalopathy, chronic hepatitis, hepatic artery thrombosis, hepatic adenoma, sepsis, liver dysfunction, chronic rejection, acute cellular rejection, and CMV infection) was 27.7% (95% CI: 20.42-35.67) without heterogeneity (I2 = 24.04%), as calculated by the random-effect model. The pooled proportion of GSD patients with complications related to GSD after LT, including HCC (Hepatocellular carcinoma), renal complication, muscle problems, delayed menarche, persistent neutropenia, pneumonitis, renal failure, and hepatic adenoma was 22.2% (95% CI: 7.97-40.01) with high heterogeneity (I2 = 82.47%). Subgroup analysis including the age of patients (adult/pediatric), duration of follow-up, and type of donor was conducted to investigate the resources of heterogeneity. CONCLUSION According to our investigation and review analysis, most GSD patients showed significant outcome improvement after liver transplantation. Overall, our findings showed an excellent outcome of liver transplantation in GSD patients; however, it needs further investigations to be confirmed.

Abstract
Limitations in liver transplantation and advances in cell therapy methods motivated us to study primary hepatocytes. The main challenge in using primary hepatocytes for liver regeneration is that they lose their functionalities. We aimed to develop a controlled-shape hydrogel and apply the conditioned-media of mesenchymal stromal cells (CM-MSCs) to improve in vitro hepatocyte functions. In this experimental study, following rat hepatocyte isolation by collagenase perfusion and collection of human umbilical cord CM-MSCs, a simple and precise system called electrodeposition was used to produce the patterned alginate hydrogel. To reduce the cytopathic effects, we used an indirect electrodeposition method. For characterizing this structure, mechanical properties, Fourier-transform infrared spectroscopy (FTIR), water uptake, in-vitro degradation, and hydrogel stability were studied. Urea synthesis as a basic function of hepatocytes was assessed in five different groups. Scanning electron microscope (SEM) was utilized to evaluate the primary hepatocyte morphology and their dispersion in the fabricated structure. We observed a significant increase in urea synthesis in the presence of CM-MSCs in patterned hydrogel alginate compared to 2D culture on day 3 (p<0.05). However, there was no significant difference in simple and patterned hydrogel on day 2. We found that the electrodeposition method is appropriate for the rapid fabricating of hydrogel structures with arbitrary patterns for 3D cell culture.

Abstract
Diabetes is an autoimmune disease in which the pancreatic islets produce insufficient insulin. One of the treatment strategies is islet isolation, which may damage these cells as they lack vasculature. Biocompatible scaffolds are one of the efficient techniques for dealing with this issue. The current study is aimed to determine the effect of transfected BM-MSCS with angiomiR-126 and -210 on the survival and functionality of islets loaded into a 3D scaffold via laminin (LMN). AngiomiRs/Poly Ethylenimine polyplexes were transfected into bone marrow-mesenchymal stem cells (BM-MSCs), followed by 3-day indirect co-culturing with islets laden in collagen (Col)-based hydrogel scaffolds containing LMN. Islet proliferation and viability were significantly increased in LMN-containing scaffolds, particularly in the miRNA-126 treated group. Insulin gene expression was superior in Col scaffolds, especially, in the BM-MSCs/miRNA-126 treated group. VEGF was upregulated in the LMN-containing scaffolds in both miRNA-treated groups, specifically in the miRNA-210, leading to VEGF secretion. MiRNAs' target genes showed no downregulation in LMN-free scaffolds; while a drastic downregulation was seen in the LMN-containing scaffolds. The highest insulin secretion was recorded in the Oxidized dextran (Odex)/ColLMN+ group with miRNA-126. LMN-containing biocompatible scaffolds, once combined with angiomiRs and their downstream effectors, promote islets survival and restore function, leading to enhanced angiogenesis and glycemic status.

Abstract
Gastrointestinal mast cell sarcoma is a rare variant of mastocytosis. It is a unifocal tumor with high destructive capacity and metastatic potential. Diagnosis of mast cell sarcoma can be challenging and might be so delayed that unfavorable prognosis may be expected. In this case report, we will describe our experience with a case of mast cell sarcoma in the small intestine of an elderly woman, which was diagnosed early on throughout the course of her disease and successfully treated. The patient was a 59-year-old woman who presented with abdominal pain, flushing, weight loss, and vomiting. Imaging studies supported the existence of an infiltrative neoplasm in the jejunum. Then, surgical removal of the tumor was performed. The presence of mast cells in the resected tumor was confirmed by immunohistochemistry, histopathology, and Giemsa staining. After almost a year of follow-up, the patient's overall condition was fine, and no signs of recurrence were found. This is the first reported case of successfully treated gastrointestinal mast cell sarcoma. All of the previously reported cases had been diagnosed after recurrence with no response to treatment. Our case shows the significance of early diagnosis and treatment in this condition and its impact on outcome and prognosis. That could be achieved only if the pathologist has a high suspicion for this rare disease and keeps it in the back of one's mind.

Abstract
BACKGROUND Cavernous hemangioma is a rare benign tumor which can sometimes mimic the clinical presentation and radiological findings of malignant tumors. Here we present a rare presentation of cavernous hemangioma in the mediastinum (CHM), along with a literature review among the main databases. CASE PRESENTATION We present a 48-year-old male who had suffered from persistent cough as the sole symptom of an anterior CHM. Computed tomography scan demonstrated a 12.5 × 10.8 cm mass in the anterior mediastinum. The mass was surgically resected, and histopathological evaluation established the diagnosis of CHM. The patient was discharged in good condition, in which during his four-month follow-up period, no recurrence of the tumor has been observed. CONCLUSION Although cavernous hemangioma rarely present in the mediastinum, it should be considered in the differential diagnosis of mediastinal tumors. However, our review of literature demonstrated a female dominance and average age of 40 years, with a 52% mortality rate based on previous reports.

Abstract
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.

Abstract
INTRODUCTION Fungal co-infections are considered an important complication in hospitalized patients with SARS-CoV-2 that can be attributed to disease aggravation, increased mortality, and poor outcomes. This study was conducted to determine the species distribution and antifungal susceptibility patterns of Candida isolates from hospitalized COVID-19 patients in Shiraz, Iran, in addition to associated risk factors and outcomes of co-infections with Candida species. MATERIALS AND METHODS In this single-center study, a total of 106 hospitalized COVID-19 patients were evaluated for clinical characteristics and outcomes. Species identification was performed by ITS1-5.8S-ITS2 gene sequencing. Antifungal susceptibility testing to fluconazole, itraconazole, voriconazole, posaconazole, caspofungin, amphotericin B, and nystatin was determined according to the M27-A3/S4 CLSI protocol. RESULTS Candida species were recovered from 48% (51/106) of hospitalized COVID-19 patients. Statistical analysis showed that patients who had heart failure, bacterial co-infection, and were receiving empirical antifungal therapy had a higher risk of developing Candida co-infection. In total, 71 Candida isolates were recovered, of which C. albicans (69%) was the most prevalent isolate. The majority of the Candida isolates were susceptible to all classes of tested antifungal drugs. DISCUSSION Our results elucidate a high rate of Candida co-infections among hospitalized COVID-19 patients. Comorbidities such as heart failure, HTN, COPD, bacterial infections as well as therapeutic interventions including catheterization, mechanical ventilation, and ICU admission increased the risk of Candida spp. isolation from the bloodstream, respiratory tract and urine samples, which led to a higher in-hospital mortality rate. Additionally, obtained data clarified that empirical antifungal therapy was not as successful as anticipated.

Abstract
BACKGROUND Different types of non-hepatorenal tyrosinemia are among the rare forms of tyrosinemia. Tyrosinemia type II and III are autosomal recessive disorders caused by pathogenic variants in the tyrosine aminotransferase (TAT), and 4-hydroxyphenyl-pyruvate dioxygenas (HPPD) genes, respectively. There are still unclarified aspects in their clinical presentations, mutational spectrum, and genotype-phenotype correlation. MAIN BODY In this study, we evaluated the spectrum of TAT and HHPD gene mutations in patients with tyrosinemia type II and III. Moreover, biochemical and clinical findings are evaluated to establish a genotype-phenotype relationship in the above-mentioned patients. Thirty-three TAT variants have been reported in 42 families, consisting of 21 missense variants, 5 frameshift variants, 4 nonsense variants, 2 variants that primarily cause splicing site, and 1 skipping complete exon (large deletion). The most common variant is p.Arg57Ter, causing a splicing defect, and resulting in premature termination of translation, which was found in 10 patients from 3 families. In HPPD gene, eleven variants in 16 patients have been reported including 7 missense variants, 2 nonsense variants, 1 splice defect, and 1 frameshift variant so far. All variants are unique, except for p.Tyr160Cys, which is a missense variant found in two different patients. Regarding genotype-phenotype correlations, in 90% of tyrosinemia type II patients, positive clinical and biochemical correlations with a detected variant are observed. In HPPD gene, due to the small number of patients, it is not possible to make a definite conclusion. CONCLUSION This is the first large review of variants in TAT and HPPD, highlighting the wide spectrum of disease-causing mutations. Such information is beneficial for the establishment of a privileged mutation screening process in a specific region or ethnic group.

Abstract
OBJECTIVES Inosine triphosphate pyrophosphatase is an enzyme encoded by the ITPA gene and functions to prevent the incorporation of thiopurine nucleotides into DNA and RNA. Thiopurine drug metabolites such as azathioprine and 6-mercaptopurine have been included in the lists of inosine triphosphate pyrophosphatase substrates. Inosine triphosphatase gene alterations are other pharmacogenetic sequence variants possibly involved in thiopurine metabolism. This study aimed to evaluate the possible association between ITPA 94C>A gene sequence variant (C-to-A substitution at nucleotide 94) in liver transplant recipients. MATERIALS AND METHODS The genotyping of ITPA 94C>A was evaluated by the polymerase chain reaction- restriction fragment length polymorphism method in 200 liver transplant recipients as well as 100 controls. Data were analyzed with SPSS statistical software. RESULTS This study showed statistically significant associations between the CA genotype of the ITPA 94C>A sequence variant and liver transplant in the rejection and nonrejection groups. Moreover, the results reported in this study showed no significant differences between sex, age, and blood group in patients with liver transplant (with or without transplant rejection). CONCLUSIONS Our results indicated that there were statistically significant associations of the CA genotype of ITPA 94C>A sequence variant with liver transplant in the rejection and nonrejection groups. Further studies are recommended.

Abstract
BACKGROUND Model for end-stage liver disease (MELD) is currently used for liver transplantation (LT) allocation, however, it is not a sufficient criterion. OBJECTIVE This current study aims to perform a hybrid neural network analysis of different data, make a decision tree and finally design a decision support system for improving LT prioritization. MATERIAL AND METHODS In this cohort follow-up-based study, baseline characteristics of 1947 adult patients, who were candidates for LT in Shiraz Organ Transplant Center, Iran, were assessed and followed for two years and those who died before LT due to the end-stage liver disease were considered as dead cases, while others considered as alive cases. A well-organized checklist was filled for each patient. Analysis of the data was performed using artificial neural networks (ANN) and support vector machines (SVM). Finally, a decision tree was illustrated and a user friendly decision support system was designed to assist physicians in LT prioritization. RESULTS Between all MELD types, MELD-Na was a stronger determinant of LT candidates' survival. Both ANN and SVM showed that besides MELD-Na, age and ALP (alkaline phosphatase) are the most important factors, resulting in death in LT candidates. It was cleared that MELD-Na <23, age <53 and ALP <257 IU/L were the best predictors of survival in LT candidates. An applicable decision support system was designed in this study using the above three factors. CONCLUSION Therefore, Meld-Na, age and ALP should be used for LT allocation. The presented decision support system in this study will be helpful in LT prioritization by LT allocators.

Abstract
Cytomegalovirus (CMV) reactivation remains a common opportunistic infection with a prominent role in immune reconstitution in organ transplant recipients. CMVs as important drivers of natural killer (NK) cell differentiation has been indicated to prompt several phenotypic and functional alteration in these cells. We aimed to monitor the reconstitution of NK cells and change the signature of inflammatory proteins at the critical phase of CMV reactivation over six months after kidney transplantation. The present study indicated that CMV reactivation is associated with the development of IL-6, IL-10, and cytotoxic granules, including granzyme-B and granulysin, and the drop in the frequency of CD16 + NKG2A-CD57 + NK cell subset in kidney transplant recipients (KTRs) with reactivation versus non- reactivated ones. Our findings describe distinct immune signatures that emerged with CMV reactivation after kidney transplantation, which may be helpful in the timely management of CMV infection in KTRs.

Abstract
Background Recently, an unknown hepatitis outbreak among children has concerned many individuals worldwide. These cases are frequently reported, mainly from Europe and other countries. In this study, we present two similar patients, who, to the best of our knowledge, are the first cases reported in the Middle East (Shiraz, Fars Province, Iran). Unlike in similar cases reported up until 30 April 2022, our patients’ hepatitis eventually resulted in aplastic anemia. Case presentation In this study, we present cases of two Iranian boys aged 13 and 8 years with hepatitis of unknown origin who developed aplastic anemia in the course of hospitalization. Conclusions Hepatitis-associated aplastic anemia is a well-known immune-mediated form of aplastic anemia that we detected in our patients and treated with immunosuppressive therapy. One patient established a satisfactory response to the treatment, but unfortunately, the other was declared brain dead.

Abstract
BACKGROUND AND OBJECTIVES There are several cPRA websites based on large enough samples in Eurotransplant, the United Network for Organ Sharing (UNOS), and the Canadian Transplant Registry (CTR). On the other hand, those calculators can differ based on the ethnicity to which they are applied. We developed the Iranian PRA calculator and compared it with UNOS and CTR calculators. METHODS The allele and haplotype frequencies of the Iranian donor pool were estimated using the HLA typing of 523 deceased Iranian kidney donors. The Organ Procurement and Transplantation Network formula was used to generate cPRA (cPRA frequency). We also used a computer script to compare the undesirable antigens of patients with the human leukocyte antigen (HLA) phenotype of donors (cPRA filtering). A total of 100 anti-HLA antibody profiles were determined in 100 sensitized individuals on the waiting list, and cPRA was estimated using various PRA calculators. RESULTS Variable allelic frequencies were obtained from population heterogeneity in each calculator's donor panel. However, no significant changes in cPRA were identified between the Iranian calculator, UNOS, and the Canadian online calculators. Lin's concordance correlation coefficient of .98 showed that cPRA (freq) and cPRA (filter) values had almost perfect agreement. INTERPRETATION AND CONCLUSION The cPRA values from the Iranian calculator are comparable to those from UNOS and CTR calculators. The donor filtering method was more useful because of factors like cost and flexibility. It also makes it easier to update cPRA on a regular basis.

Abstract
INTRODUCTION Islet transplantation has been introduced as a promising approach for the treatment of diabetes mellitus type 1. Despite many efforts to achieve a perfect treatment, further investigation is still needed to eliminate limitations and challenging issues. The objective of the present systematic review is to evaluate the efficacy of islet transplantation in diabetes mellitus type 1. EVIDENCE ACQUISITION We conducted a systematic review on the results of clinical studies on islet cell transplantation between January 2015 and November 2021. The Search strategy was designed and conducted in PubMed, Cochrane, Scopus, and Web of Science. EVIDENCE SYNTHESIS Studies have indicated that islet transplantation can reduce the daily insulin requirement as well as improving metabolic stability in diabetic patients. Even in some patients, insulin independence was achieved during the first year of transplantation. CONCLUSIONS Findings show that islet transplantation has a potential to become a promising treatment for diabetes mellitus type 1. In this regard, to obtain a trustworthy result, it is essential to design clinical studies (RCTs) with large sample size and long follow-up (cohort studies) to achieve a comprehensive and accurate appraisal of islet transplantation.

Abstract
There are a limited number of studies regarding the involvement of viruses in the development and pathogenesis of renal cell carcinoma (RCC). In this study, we aimed to discover whether human herpesvirus 6A (HHV-6A) and 6B (HHV-6B) and human polyomavirus JC (JCV) and BK (BKV) are associated with RCC and the expression of p53, p16INK4a, Ki-67 and NF-κB in RCC patients. A total of 122 histologically confirmed RCC tissue specimens and 96 specimens of their corresponding peritumoral tissues were included in this prospective study. Nested polymerase chain reaction (nPCR) was performed in order to amplify viral DNA sequences. Restriction endonuclease analysis was carried out to discriminate between HHV-6A and HHV-6B. p53, p16INK4a, Ki-67, and NF-κB immunostaining data of the studied tissue specimens were available from our previous study. Statistical analysis was performed to demonstrate the potential associations. HHV-6B and JCV were detected in 10.7% and 13.9% of RCC patients, respectively. We did not detect HHV-6A and BKV in any of RCC tissue specimens. Moreover, no association was found between either of these viruses and RCC. Our study revealed a significant association between HHV-6B and p53 overexpression. No other associations were found between cellular biomarkers p53, p16INK4a, Ki-67, and NF-κB and the studied viruses. The data of the present study, though very limited, disprove the involvement of HHV-6A, HHV-6B, BKV, and JCV in the initiation or progression of RCC. This article is protected by copyright.

Abstract
Background:Type 1 diabetes is an autoimmune disorder characterized by the loss of pancreatic islets. Islet allotransplantation is a potentially beneficial therapeutic approach for diabetes. Islets suffer a variety of cellular insults including ischemia and partial vascular loss during isolation, resulting in a significant reduction in viability prior to transplantation. The present study aimed to investigate the effect of angiogenic microRNA (miRNA)-126 and -210 on islet function and viability in an indirect way. Methods:Poly Ethylenimine (PEI)-miRNA-126 and -210 polyplexes were constructed at various Nitrogen/Phosphate (N/P) ratios. After confirmation by gel retardation and ethidium bromide dye exclusion assay, its cytotoxicity and transfection efficiency were analyzed by MTT and fluorescent assays, respectively. After that, the selected polyplexes were used to transfect Human Umbilical Vein Endothelial Cells (HUVECs) in vitro and were indirectly co-cultured with islet cells for three days. Real-time polymerase chain reaction and enzyme-linked immunoassay were conducted to verify the regulation of target genes and the functionality of the islets. Results:The findings showed that PEI could condense miRNAs at N/P=5. The viability of the HUVECs was decreased by increasing the amount of PEI. Additionally, ployplex-126 and -210 led to a decrease in the expressions of target genes, phosphoinositol-3 kinase regulatory subunit 2, sprouty-related EVH1 domain-containing protein 1, and ephrin-A3 in the islets. Moreover, the expressions of Bax and Bcl2 and their ratio in the treated groups by polyplex-126 and -210 led to better survival and function of the islets, with a higher expression of insulin and response to glucose stimulations. Furthermore, polyplex-210 could downregulate the anti-angiogenic protein, thrombospondin 1, compared to the other groups. Finally, the secretion of C-peptide was higher in polyplex-210 than in the other groups, adjusted for insulin secretion. Conclusion:The results indicated that angiogenic miRNAs could promote the survival and function of islet cells by interacting with their targets.

Abstract
BACKGROUND AND AIM Prostate cancer is the second most common cancer among men that has affected their quality of life. This study aimed to find prostate tissue-specific genes using bioinformatics methods to specifically target prostate cells in case of metastasis to other tissues. MATERIALS AND METHODS In this study, after finding a specific gene (MSMB) that is highly expressed in cancer, the optimal promoter region of this gene was isolated and inserted in an expression vector. Then, this vector was transfected into two prostate cancer cell lines (DU145 and LNCaP) and three non-prostate cell lines (LX-2, MRC-5, and U87) using the PEI chemical method. The expression of this vector in these cells was examined using fluorescent microscopy and flow cytometry. RESULTS We observed that the expression of MSMB promoter in DU145 cell line has a much higher activity than the CMV promoter, which is a ubiquitous promoter. The MSMB promoter didn't show any activity in cells other than that of prostate derived cell lines. CONCLUSION MSMB gene promoter with specific expression and high efficiency in prostate tissue compared to CMV promoter can play an essential role in gene therapy of prostate cancer.

Abstract
Pleomorphic hyalinizing angiectatic tumor (PHAT) is a rare tumor of the soft tissue, usually located in lower extremities. There are rarely tumors reported in other anatomic locations. Herein, we report retroperitoneal PHAT in a male patient. A 41-year-old man was referred to our clinic due to an incidentally found retroperitoneal mass. Computed tomography (CT) scan showed a solid hypoechoic lesion containing fat component and calcified elements measuring about 80*72*45 mm in the right lower quadrant (RLQ) of the abdomen. Magnetic resonance imaging (MRI) showed circumscribe lesion measuring about 60 x 48 mm with partial enhancement and fat component. In pelvic exploration, a large mass was found that had encased the right external iliac artery and vein. Therefore, the mass and its surrounding iliac vessels were excised and removed en block. Then, the external iliac vessels were reconstructed with Gortex graft. No recurrence was found in 1 month and 3 months post-operation follow up. We report a pelvic retroperitoneal PHAT as a rare location of this tumor. It seems that PHAT must be considered in differential diagnosis in patients with soft tissue tumors in the pelvic cavity.

Abstract
Background Endotracheal tumors are rare in the respiratory system. Myoepitheliomas are benign tumors, which are rarely reported in the respiratory system. Herein, we report a rare case of endotracheal myoepithelioma, which was resected by rigid bronchoscopy.
Case presentation A 36-year-old man, presenting with chest pain, dyspnea, stridor, and hemoptysis, was referred to our center with radiological features of near-total tracheal obstruction due to mass. Fiberoptic bronchoscopy with argon plasma coagulation and rigid bronchoscopy with grasper forceps was utilized to resect the mass. Pathological evaluation of the mass demonstrated myoepithelioma. The patient was discharged in good condition. Now, after 6 months, the patient is symptom-free with no evidence of tumor recurrence or re-growth. Conclusions Despite being extremely rare, myoepithelioma should be considered a possible differential diagnosis for endotracheal tumors. Fiberoptic and rigid bronchoscopy management is an effective method for the resection of endotracheal tumors.

Abstract
OBJECTIVES Glycogen storage diseases (GSDs) are heterogeneous disorders caused by various enzyme deficiencies. GSD type IX α2, the most common subtype of GSD IX, is due to a deficiency of hepatic phosphorylase kinase. Herein we will report a novel mutation in this disease with an unusual presentation. CASE PRESENTATION we describe a 3-year-old boy who suffered from hepatomegaly, fatty liver disease, and liver cirrhosis. The cause of cirrhosis at a young age was unknown based on the laboratory data and liver biopsy, so we performed a targeted-gene sequencing (TGS) covering 450 genes involved in inborn metabolic diseases consisting of glycogen storage disorders genes with hepatic involvement. He was found out to have a rare novel pathogenic variant in the PHKA2 gene. CONCLUSIONS This novel variant c.2226+2T > C expands the mutational spectrum of the PHKA2 gene. Also, severe liver damage (cirrhosis) in patients with GSD- IX α2 has rarely been reported, which needs further discussion. We hypothesize that unidentified PHKA2 variants may be a rare cause of childhood liver cirrhosis.

Abstract
Background
Glycogen storage diseases (GSDs) are inherited glycogen metabolic disorders which have various subtypes. GSDs of type I, III, IV, VI, and IX show liver involvement and are considered as hepatic types of GSDs. Thus, liver transplantation (LT) has been proposed as a final therapy for these types of GSD. LT corrects the primary hepatic enzyme defect; however, the long-term outcomes of LT in these patients have not been extensively evaluated so far. There are few reports in the English literature about the outcome of GSD patients after LT. There has been no report from Iran. The present retrospective study aimed to evaluate the long-term outcomes of eight patients with GSD types I, III, and IV who underwent LT in the affiliated hospitals of Shiraz University of Medical Sciences, from March 2013 to June 2021. During this period, there were no patients with GSD VI and IX identified in this center.
Results
The median time of diagnosis of the GSDs and at transplant was 1 year and 11 years, respectively. All eight transplanted patients were alive at the time of follow-up in this study. None of them required a re-transplant. All of the patients showed normalized liver enzymes after LT with no sign of hypoglycemia.
Conclusions
LT is an achievable treatment for end-stage hepatic involvement of GSDs with a cure for metabolic deficiency. Our experience in these eight patients shows a favorable outcome with no mortality and no major complication.

Abstract
BACKGROUND There have been few studies regarding viral involvement in the pathogenesis of renal cell carcinoma (RCC). The aim of this study was to examine the possible association of Epstein-Barr virus (EBV) infection with clinicopathological features and cellular biomarkers including p53, p16INK4a, Ki-67 and nuclear factor-kappa B (NF-κB) in RCC tumors. METHODS In this prospective study, 122 histologically confirmed Formalin-fixed Paraffin-embedded RCC tissue specimens along with 96 specimens of their corresponding peritumoral tissues and 23 samples of blunt renal injuries were subjected to nested polymerase chain reaction (nPCR) in order to amplify EBV DNA sequences. The expression of p53, p16INK4a, Ki-67 and NF-κB was investigated by immunohistochemistry (IHC) assay. Statistical analysis was employed to demonstrate the possible associations. RESULTS Infection with EBV was found to be significantly associated with RCC. Our results indicate that p65 NF-κB signaling pathway is probably involved in EBV-mediated RCC pathogenesis. Moreover, we found p53, Ki-67 and cytoplasmic NF-κB expression to be associated with tumor nuclear grade in RCC patients. The expression of p53 and Ki-67 was associated with primary tumor category as well. In addition, p53 overexpression was significantly more frequent among nonconventional RCC tumors than the conventional histologic type. CONCLUSIONS Infection with EBV is likely to play an important role in the development of RCC through the constitutive and permanent activation of NF-κB p65 signaling pathway. However, more experiments and supporting data are required to reach a decisive conclusion.

Abstract
Background Undifferentiated embryonal sarcoma of the liver (UESL) is a rare liver tumor accounting for 6–13% of primary liver tumors. Accurate preoperative diagnosis is difficult, with a rather high misdiagnosis rate. Herein, we reported a very large UESL treated with anatomical resection. Our case is amongst the largest pediatric UESLs in the literature. Case presentation Herein, we report a 13-year-old girl presenting with right upper quadrant abdominal pain, postprandial vomiting, and abdominal distention, in which radiographic imaging demonstrated a huge UESL (28 × 20 × 12 cm). The patient was treated with partial hepatectomy and the 5 kg tumor was removed. The patient was discharged in good condition, with no significant complaints in her follow-up. Conclusions Although different treatment strategies have been reported for UESL cases, anatomical resection is still the main treatment approach, especially for large tumors.

Abstract
Background Gastric cancer is one of the lethal cancers and there is no effective treatment for these patients and still, 5-year survival rate is about 25% to 30%. Finding reliable biomarkers for early-stage diagnosis, targeted therapy, and survival prediction is a priority in this cancer. Objectives In this study we were trying to know about the molecular classification of gastric cancers in a group of patients from the South of Iran. Patients and Methods In a cross sectional study, 50 specimens of gastric cancer were selected that have enough tissue to be stained by immunohistochemistry (IHC). IHC was performed for Her-2, mismatch repair genes (MLH-1, MSH-2, MSH-6, and PMS-2), and PDL-1. Frequency of positive makers was compared with survival and outcome. Results and Conclusion In our study, deficient MMR (dMMR) was detected in 4 patients (8.0%). PD-L1 expression in tumor cells (TC) was observed in 1 of 4 cases (25%) with PMS2 loss. However, PD-L1 in TCs and TILs (tumor infiltrating lymphocytes) was negative in 1 case with MLH1 loss and in 3 of 4 cases with PMS2 loss, which was not statistically significant. All of our 50 cases were positive for MSH2 and MSH6, 24% of which showed TCs with PDL-1 expression and 32% of them in TIL. HER2 was positive in 2 (2/50, 4.0%) cases, among which all of the cases were positive for PD-L1 expression in TCs and TILs, respectively. However, in HER2-negative group, 26.2% (11/42) and 28.6% (12/42) of tumors were positive for PD-L1 in TCs and TILs, respectively. The expression rate of PD-L1 in HER2 negative TCs was significantly higher than that in HER2 positive TCs (P = .033). Immunohistochemistry for Her-2 was equivocal in 6 cases (12.0%) none of which expressed PD-L1 in tumor cells. In our study minimum and maximum survival times from detection of gastric cancer were 1 and 87 months, respectively. The mean ± SD and median ± SD of overall survival time were 30.69 ± 4.88 and 18 ± 1.45 months, respectively. One and 3-year survival rates of 40% and 24%, respectively. PD-L1 expression was not associated with survival, but its expression was associated with intestinal type Lauren classification and negative HER-2. PD-L1 positivity in tumor cells or tumor infiltrating lymphocytes was not an independent prognostic factor in gastric cancer.

Abstract
The existence of primary renal lymphoma (PRL) in the kidney has long been debated due to its extranodal location and lack of lymphatic channels. Primary renal lymphoma is extremely rare, accounting for less than 1%, and is frequently misdiagnosed as renal cell carcinoma (RCC). We present a 50-year-old man presenting with right flank pain in the last week. The computed tomography scan showed a large isodense right renal mass with a small para-aortic lymph node suspected of RCC. The patient underwent right radical nephrectomy and lymphadenectomy with an uneventful postoperative outcome. The histopathology and immunohistochemistry showed diffuse large B-cell lymphoma. Then, the patient received five-cycle chemotherapy and regional radiotherapy. Within five years of follow-up, no symptoms of recurrence. In conclusion, even though PRL is a rare tumor type. An effort should be made to make a preoperative diagnosis because PRL can be treated with systemic chemotherapy instead of other renal tumors requiring nephrectomy.

Abstract
INTRODUCTION Despite developing strategies for antiviral treatment, cytomegalovirus (CMV) infection remains one of the most common challenges in kidney transplant recipients (KTRs). The evaluation of CMV viral load is still the most practical main clinical approach for CMV assessment and guides decision-making in recipient antiviral treatment. However, there is not a specific viral load cut off for initiating treatment yet. On the other hand, the cellular immune system and the innate immune response prove their roles in diagnosing CMV reinfection and monitoring the therapeutic regime to control CMV. Interactions among the components of cellular immunity encounter CMV reactivation provide a strong treatment management plan for clinical decisions about antiviral therapy against CMV. Natural killer (NK) cells, as essential effector cells, present potentially antiviral activity through distinct subpopulations. CCR7expressing NK cells were identified by high cytotoxicity and functionality among NK cell subsets. Here, we explored the correlation between CCR7+ expressing NK cells with viral load in CMV reactivated-kidney transplant recipients. MATERIALS AND METHODS A cross-sectional study was conducted among ten CMV reactivated KTRs. The CMV DNA copy number was evaluated utilizing real-time PCR.NK cell phenotypic profiling was done using flow cytometry. RESULTS Increasing of CMV viral load in CMV reactivated KTRs had a negative correlation with CCR7+CD57+ CD56/CD16+ NK cell (P < .05 r = -0.7) after CMV reactivation. Significantly increased level of CCR7-CD57- CD56/CD16+ NK cell was associated with CMV viral load within CMV reactivated KTRs (P < .05, r = 0.68). CONCLUSION CCR7 expression is associated with CMV reactivation, which offers a new aspect of CMV-associated immunity within the NK cell compartment. DOI: 10.52547/ijkd.6721.

Abstract
Background: Epidemiologic studies have shown world-wide increasing incidence of
ulcerative colitis (UC) as an autoimmune disease of intestine. In the
meantime, gastrointestinal H. Pylori infection is being decreased. Objectives: There are very few studies about comparing the presence of H. Pylori in the
colon and the disease activity of UC. There is no study form Iran. In this
study, we tried to investigate the presence of H. Pylori in the mucosa of
colon by molecular and microbiological as well as pathological methods to
find any association between the presence of this organism in the colon and
the presence and activity of UC. Patients and Methods: In 100 patients who referred to colonoscopy clinic, colonoscopy was
performed. Fifty-seven patients with the new diagnosis of UC were considered
as cases and 43 patients with normal screening colonoscopy for polyps were
considered as controls. Colon biopsies were evaluated according to
histopathology, clinical findings, and laboratory results to confirm the
diagnosis and the degree of activity in the cases of UC. Molecular studies
were also performed to evaluate the presence of H. Pylori genome in the
colon biopsies. A sample of colon was also cultured for H. Pylori. ELISA
test was performed in a sample of blood to evaluate the level of IL-10 and
IL-17 as regulatory cytokines of inflammation. Results: Cases with the diagnosis of UC showed significantly higher number of positive
colonic H. Pylori comparing to normal colonic mucosa. Also, the presence of
H. Pylori genome in the colon was associated with higher activity in the
cases with UC and higher levels of inflammatory mediators especially IL17
and lower levels of inhibitory mediators such as IL-10. Conclusion: Colonic colonization of H. Pylori was higher in the patients with UC and
higher activity of this disease comparing with normal control colonic
mucosa.

Abstract
Natural killer (NK) cells are essential for controlling certain viral infections, including cytomegalovirus (CMV). In particular, the importance of NK cells in the context of CMV infection is underscored by the adaptive capabilities of these cells. Evidence suggests that some viruses can directly interfere with NK cell compartments and their activation and lead to shape-shifting the NK cell receptor repertoire. Still, it remains unknown whether the CMV can interact with NK cells without intermediaries. Here, we examined whether the direct effects of CMV lysate alter phenotypical properties of NK cells. To investigate this issue, NK cells were isolated from the blood of CMV seropositive healthy donors by negative magnetic separation. Isolated NK cells were cultured in the presence of CMV lysate and analyzed for the expression of NKG2A, NKG2C, and CD57 by FACS caliber. The results showed that NKG2C expression is significantly upregulated in the presence of CMV lysate compared to without stimulated group (mean increase, 6.65 %; 95% CI, 0.2582 to 13.02; p=0.043; R square: 0.38). Likewise, results have shown a significant decrease in the frequency of NKG2A+CD57- NK cell subsets (p=0.005; 95% CI, -13.49 to -3.151; R square: 0.5957) in the stimulated group compared to without stimulated ones. According to these results, CMV may drive a direct influence on NK cell receptor repertoire, including the expansion of NK cells expressing NKG2C receptor, which is needed for further studies.

Abstract
Background Genetic abnormalities might have important role in pathogenesis of hepatic steatosis after liver transplantation. We aimed to investigate association between genetic variations in transmembrane 6 superfamily member 2 (TM6SF2) rs58542926, proprotein convertase subtilisin/kexin type 9 (PCSK9) rs505151 and proprotein convertase subtilisin/kexin type 7 (PCSK7) rs2277287 with hepatic steatosis in liver transplant recipients.
Methods In a cross-sectional study, adult (> 18 years) liver transplant recipients who were referred for their routine post-transplant follow-up between June 2018 and September 2018 were included in the study. Hepatic steatosis in transplant recipients was assessed by controlled attenuation parameter (CAP). Polymerase chain reaction-restriction fragment length polymorphism (PCR–RFLP) was used to study TM6SF2 rs58542926, PCSK7 rs2277287 and PCSK9 rs505151 genotypes. Results 107 liver transplant recipients were included. There was no association between different genotypes of PCSK9 rs505151 and PCSK7 rs2277287 with hepatic steatosis in liver transplant recipients (P value > 0.05). The presence of TT genotype of TM6SF2 rs58542926 was higher in patients with hepatic steatosis measured by CAP after liver transplantation. In patients with moderate and severe hepatic steatosis (grade 2 and 3 steatosis), AG + GG genotypes of PCSK9 rs505151 were more prevalent than AA genotype (OR 8.667; 95% CI 1.841–40.879; P value = 0.004) compared to patients with mild steatosis (grade 1). In multivariate regression model, AG + GG genotypes of PCSK9 rs505151 were associated with moderate and severe steatosis in liver transplant recipients (OR 5.747; 95% CI 1.086–30.303; P value = 0.040). Conclusions Genetic variations in TM6SF2 rs58542926 and PCSK9 rs505151 might be associated with hepatic steatosis in liver transplant recipients.

Abstract
The liver is considered a tolerogenic organ that can induce peripheral tolerance. The exact mechanisms of tolerance in the liver remain undefined. Regulatory T cells (Tregs) have been demonstrated to be involved in inducing and maintaining peripheral tolerance. They play an important role in the prevention of immune responses and autoimmunity. The main focus of this review is the role of Tregs and their subpopulation in liver transplantation. More specifically, this manuscript will highlight the recent findings about using Treg cells as a biomarker in liver transplantation. There are some reports and animal models about the role of Tregs in the process of rejection of liver transplantation. Previous reports and studies have suggested that by increasing the number of Tregs better liver transplant outcomes will be accomplished by enhancing tolerance. It has been shown that the levels of CD4 + CD25 + FOXP3+ Treg cells correlate with the inhibition of acute allograft rejection in liver transplantation; however, further studies must be done to address the potential role of Treg cells in chronic rejection. Indeed, in the future, Treg cells may have potential use as a beneficial biomarker to screen long-term graft function.

Abstract
BACKGROUND Cirrhosis is often an asymptomatic disease. Its early diagnosis before the development of life-threatening complications is an important step to prevent the progression of the disease. The aim of the present study was the identification of parameters that are significantly changed in cirrhosis, are not affected by the cause of cirrhosis, and are associated with fatal complications of cirrhosis. METHODS Demographic and pre-transplant ultrasound and laboratory findings were reviewed in patients with viral- (n = 27), autoimmune hepatitis- (n = 27), alcohol- (n = 18), primary sclerosing cholangitis- (PSC) (n = 36), and nonalcoholic steatohepatitis-related cirrhosis (n = 42). RESULTS Among laboratory findings, only the aspartate aminotransferase-to-platelet ratio index (APRI) value in cirrhotic patients was significantly higher than that of healthy individuals (p < 0.001) and, meanwhile, its value was not different among cirrhotic patients with various etiologies (p = 0.240) but was associated with the ascites, as a cirrhosis life-threatening complication (p < 0.001). CONCLUSIONS The APRI has acceptable potential to predict prognosis in cirrhosis. So, it can be a possible parameter to the prediction of the lethal complications of cirrhosis.

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 & Objective: Differential diagnosis between cholangiocarcinoma (CCA) and metastatic pancreatic ductal adenocarcinoma (PDA) in the liver is difficult and so far, no specific immunohistochemical marker is reported to differentiate these two tumors. Considering the existing literature, the level of expression of Annexins (Annexin A1, 10 and 13) have been studied for differential diagnosis between these two tumors by molecular methods and promising results have been reported. Therefore, in this study, we tried to investigate the immunohistochemical value of these three Annexins for the differential diagnosis of CCA and PDA in the liver. Methods: The articles that reported the research subject in 10 years (2009-2019), including 45 cases of CCA and 50 cases of metastatic PDA in the liver were evaluated considering the presence or absence of AnnexinA1 (ANXA1), Annexin A10 (ANXA10) and Annexin A13 (ANXA13) expression by immunohistochemistry, were investigated. Results & Conclusion: This study showed, ANXA1 was positive both in PDA and CCA, ANXA10 was positive in ~60% of PDA cases and ~40% of CCA cases, and ANXA13 was mostly negative in both groups. The best sensitivity was found in cytoplasmic and nuclear ANXA1 (80% and 84%, respectively) to distinguish PDA from CCA and vice versa. The best specificity was observed in ANXA10 and ANXA13 to distinguish PDA from CCA. Also, ANXA13 had the best specificity to distinguish CCA from PDA. Our investigations showed that, ANXA1 probably can classify positive cases correctly, but it cannot discriminate PDA from CCA. ANXA10 had fair sensitivity and specificity to discriminate PDA from CCA. ANXA13 apparently had a high specificity that can help to narrow-down the differential diagnoses.

Abstract
OBJECTIVES Estimation of liver fat among living donor candidates is necessary before living donor liver transplant. This study aimed to investigate the usefulness of the controlled attenuation parameter compared with liver biopsy for pretransplant estimation of hepatic steatosis in living liver donors. MATERIALS AND METHODS In this retrospective study, we included all individuals who underwent transient elastography with controlled attenuation parameter and ultrasonography-guided liver biopsy as a part of donor evaluations before living donor liver transplant. Clinical and laboratory data of living donor candidates were reviewed and collected. RESULTS Of 49 donor candidates included in this study, 21 (42.9%) had different degrees of hepatic macrosteatosis. Of the 21 donor candidates who had hepatic steatosis in liver biopsy, 13 individuals were diagnosed to have steatosis in transient elastography. Of the 28 donor candidates without hepatic steatosis in liver biopsy, 26 individuals showed no steatosis in transient elastography (odds ratio: 21.12; 95% CI, 3.91- 114.08; P < .001). Controlled attenuation parameter was useful in discriminating presence (P = .001) and grade of hepatic steatosis (P = .009) compared with liver biopsy with good sensitivity and specificity. CONCLUSIONS The controlled attenuation parameter is a noninvasive method for detection of hepatic steatosis in living donor candidates and can be used as an adjunct to liver biopsy for screening of living donor candidates before liver transplant.

Abstract
Cytomegalovirus (CMV) infection contributes to morbidity and mortality among kidney transplant recipients. Natural killer (NK) cells can battle against CMV in kidney transplant recipients (KTRs). This study aimed to analyze the association between CMV reactivation and the proportion of NK cell subsets and their activity. In a cross-sectional study, ten CMV reactivated KTRs, and ten non- CMV reactivated ones were recruited. Ten matched healthy controls were also included in this cohort. The presence of anti-CMV-IgG Ab in both KTR subgroups from seronegative donors and healthy controls was determined. The frequency of distinct subsets of memory-like NK cells was analyzed through NKG2C, NKG2A, and CD57 using flow cytometry. The activity of NK cells was evaluated after stimulation via coculture with K562 cell line and then assessment of the frequency of CD107a and granzyme B. The mRNA levels of transcription factors, including T-bet, EAT, and inflammatory proteins, including IFN-γ and perforin contributing to NK cell activation, were also evaluated. Results showed a significantly lower frequency of NKG2C + NKG2A-CD57+ NK cell population in CMV-reactivated KTRs compared to non-reactivated ones (P-value:0.003). NKG2C+ NK cells expressing CD107a/LAMP-1 significantly was increased in CMV-reactivated KTRs compared to non-reactivated ones (P-value: 0.0002). The mRNA level of IFN-γ had a significant increase in the CMV-reactivated KTRs vs. nonreactive ones (P-value: 0.004). Finally, evaluation of the NK cells' cytotoxicity and activity through assessment of CD107a/LAMP-1 expression and IFN-γ secretion may be helpful for the identification of the risk of CMV reactivation in KTRs.
