Item Auxiliary Liver Transplantation for Acute Liver Failure.(2016-01) Shanmugam, Naresh P; Al-Lawati, Tawfiq; Kelgeri, Chaya; Rela, MohamedBackground: Auxiliary partial orthotopic liver transplantation is a technique where part of diseased native liver is removed and replaced with healthy donor liver so that, the left behind native liver could later regenerate. Case characteristics: 2½-year-old girl with acute liver failure due to Hepatitis A. She underwent a successful auxiliary partial orthotopic liver transplantation. Outcome: Successful native liver regeneration and immunosuppression withdrawal after two and half years of surgery. Message: In selective cases of acute liver failure, auxiliary partial orthotopic liver transplantation could provide a chance for native liver regeneration and immunosuppression-free life.Item Genotypic Detection of Epstein-Barr Virus in Pediatric Transplant Recipients From India.(2015-11) Janani, Madhuravasal Krishnan; Malathi, Jambulingam; Rela, Mohamed; Farouk, Mohammed; J, Padmapriya; Madhavan, Hajib NObjective: To determine the rate of occurrence and genotypes of Epstein-Barr Virus (EBV) among pediatric renal and liver transplants recipients. Design: Observational study. Setting: Vision Research Foundation referral center and Institute of Liver Disease and Transplantation, Chennai, India. Participants: 70 pediatric solid organ transplant recipients and 60 voluntary healthy donors. Methods: Polymerase chain reaction (PCR) for detection and genotyping of EBV were carried out using genes targeting Viral capsid antigen, Nuclear antigen 1, 2 and 3, followed by real time PCR for viral load determination and further confirmed by phylogenetic analysis. Results: EBV was detected in 35 (51.4%) samples (32 liver and 4 renal transplants) with high viral load. Type A was detected in 33 samples, Type B in 2 liver transplant patients, and co-infection in one liver transplant patient who developed Post-transplant Lymphoproliferative Disorder (PTLD). Real time PCR results correlated with conventional PCR. The mean viral load for patients who did not develop PTLD was 50,424 copies/mL. Overall EBV load in patient with PTLD ranged from 1,40,392 copies/mL prior to PTLD diagnosis to 62,124 copies /mL post treatment. Conclusion: EBV infection is the high risk factor for PTLD after liver transplantation. PCR targeting of EBV can be applied to diagnose EBV infections and monitor treatment for EBV in pediatric solid organ transplant recipients.Item Hepatic metastasis with heterologous rhabdomyoblastic differentiation in a patient with gastrointestinal stromal tumor treated with imatinib.(2013-07) Vij, Mukul; Patra, Susama; Rela, MohamedGastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the intestinal tract. In patients with locally advanced and/or metastatic GIST, the introduction of tyrosine kinase inhibitor, imatinib mesylate, has transformed the management of this previously untreatable neoplasm into a treatable entity. Approximately 80% of advanced metastatic GISTs respond to imatinib treatment. However, the majority of patients suffer disease progression at a median of 2 years due to drug resistance. Generally progressing GISTs retain their typical morphology. Herein, we report an extremely rare case of progressive metastatic GIST with heterologous rhabdomyoblastic differentiation after, imatinib mesylate treatment. We also review the relevant literature.Item Hepatic solitary fibrous tumor: Report of a rare case.(2012-04) Patra, Sushma; Vij, Mukul; Venugopal, K; Rela, MohamedSolitary fibrous tumor (SFT) of the liver is an extremely rare neoplasm of mesenchymal origin. In the English literature, less than 40 cases of SFTs of the liver have been reported. The present case concerns a 34-year-old female who presented to us with complaint of dyspepsia. On examination, there was hepatomegaly. On ultrasound examination, an SOL in the liver was detected. Large tumor measuring 14.5 × 10 × 8 cm was resected. Microscopic evaluation of the tumor showed a well-circumscribed, low to moderately cellular tumor demonstrating spindle- and fibroblast-like cells within the collagenous stroma. Immunohistochemistry revealed diffuse strong cytoplasmic immunopositivity of CD34, Bcl2, and vimentin. A diagnosis of a benign SFT was given. The patient remained well 4 years after surgery. SFT is a rare mesenchymal neoplasm that occasionally involves the liver in adult patients. Most SFTs are benign, but some may have malignant histological features. With less than 40 reported cases in the literature, little can be said regarding its natural history or the benefits of adjuvant radio chemotherapy. Complete surgical resection remains the cornerstone of its treatment.Item Liver transplantation in children.(2002-02-04) Rela, Mohamed; Dhawan, AnilThe results of liver transplantation has improved significantly in the last decade with one year survival figures close to 90% for children with chronic liver disease. This can be attributed to improvement in surgical techniques, better postoperative care and newer immunosuppresive drugs. As a result of this, increasing number of children are referred for transplantation with no significant increase in the number of solid organ donors. The earliest transplants in children were performed using organs from size matched pediatric donors. However, as the pediatric donor numbers were limited, liver reduction techniques were developed to transplant small children before deterioration. Increasing experience with reduced livers led to the development of split liver, living donor and auxiliary liver transplantation. Better management of immunosuppressive drugs and newer agents such as Mycophenolate Mofetil have reduced the incidence of graft loss due to chronic rejection and long-term renal toxicity. The goal for the future will remain to be transplantation without the use of long-term immunosuppression.Item Pigmented hepatocellular adenoma with complete CD34 immunostaining pattern: A diagnostic dilemma.(2012-10) Vij, Mukul; Patra, Sushma; Rela, MohamedWHO defines hepatocellular adenoma (HCA) as a benign tumor composed of cells closely resembling normal hepatocytes, which are arranged in plates separated by sinusoids. It is more common in women. The present concerns a 41 years female who was found to have a mass lesion in liver on ultrasound while undergoing routine evaluation for dyspepsia. Computed tomography scan of abdomen showed 10 × 8 cm lesion in liver. Extended left hepatectomy was performed. Grossly hepatic cut surface showed circumscribed tumor with dark gray or black color. Microscopy revealed hepatocellular adenoma with abundant Dubin Johnson like pigment deposition. CD34 immunostaining showed complete sinusoidal pattern. We labeled the tumor as pigmented hepatic adenoma with complete CD34 staining pattern. To the best of author's knowledge only eight cases of pigmented hepatocellular adenoma are described in world literature.Item Recent Trends in the Diagnosis and Management of Biliary Atresia in Developing Countries.(2015-10) Ramachandran, Priya; Safwan, Mohamed; Reddy, Mettu Srinivas; Rela, MohamedNeed and purpose of review: Biliary atresia is a progressive obstructive cholangiopathy and is fatal if left untreated within 2 years of life. Delay in referral is because of difficulties in differentiating it from physiologic jaundice and identifying an abnormal stool color. This paper presents an overview on the diagnosis and discusses the current strategies in the management of this disease in developing countries. Methods: Articles were retrieved from the PubMed database using the terms ‘biliary atresia’, ‘Kasai portoenterostomy’ and ‘pediatric liver transplantation’. Contents of the article are also based on personal experience of the authors. Conclusion: A national screening program using stool color cards as part of standard care in the neonatal period will greatly improve early detection of biliary atresia. Outcomes will improve if it is diagnosed at the earliest after birth, the child is referred to an experienced pediatric hepatobiliary unit for evaluation, and undergoes an early Kasai procedure. If an early Kasai portoenterostomy is performed, nearly half of all children survive into adolescence, and about one-third are likely to have a long-term, symptom-free life with normal liver biochemistry. Sequential treatment combining Kasai as first line and liver transplantation as second line results in 90% survival for children with biliary atresia.Item Wolcott-Rallison Syndrome- Endocrinopathy with Recurrent Acute Liver Failure(Indian Academy of Pediatrics, 2019-12) Shanmugam, Joseph J; Shanmugam, Naresh; Rela, MohamedA 2-yr-old child with early onset diabetes and hypothyroidism,and diagnosed as Wolcott-Rallison Syndrome, developed twoepisodes of acute liver failure and recovered, but he remains athigh risk of developing another episode of acute liver failure.Autoimmune, metabolic or genetic disorders should be evaluatedin children with recurrent acute liver failure and genetic testsneeds to be considered
