Item Expanded dengue syndrome presenting with acute liver failure, acute kidney injury, pancreatic involvement, coagulopathy, and multiple intracranial hemorrhages in a young child: a case report(BioMed Central, 2022) Thadchanamoorthy, V.; Dayasiri, K.Background: Dengue is a mosquito-borne viral infection that typically occurs in tropical and subtropical countries. The clinical manifestations of dengue infection range from an asymptomatic subclinical course to severe dengue shock syndrome. Besides, dengue can affect any organ in the body and can present with atypical manifestations. Case presentation: We report a 6-year-old previously healthy Tamil child who had dengue complicated with multiorgan involvement. She initially presented with high fever, headache, body aches for 5 days, blood and mucus diarrhea, hematuria, and right knee joint swelling for 2 days. Dengue NS1 antigen was positive on day 2 of febrile illness. She was managed symptomatically in the local hospital for 3 days and transferred to the tertiary care hospital for further management. She was eventually diagnosed as having dengue hemorrhagic fever complicated with multiorgan involvement including acute liver failure, pancreatic involvement, coagulopathy, arthritis, acute kidney injury, and multiple intracranial hemorrhages. The constellation of disease manifestations was identified as expanded dengue syndrome. She was managed with fresh blood, platelet, and cryoprecipitate transfusions and intravenous antibiotics in addition to renal and liver support in the intensive care unit. On day 14 of illness, she deteriorated while on the ventilator and died due to multiple intracranial hemorrhages. Conclusion: The reported child with dengue hemorrhagic fever developed several unusual presentations such as acute liver and renal failure, disseminated intravascular coagulopathy, pancreatic involvement, and multiple intracranial hemorrhages, which form part of expanded dengue syndrome. In the seriously unwell child, it is important to look for unusual complications actively to improve outcomes.Item Acute-on-chronic liver failure:consensus recommendations of the Asian Pacific association for the study of the liver (APASL):an update.(Springer,, 2019) Sarin, S.K.; Choudhury, A.; Sharma, M.K.; Maiwall, R.; Al Mahtab, M.; Rahman, S.; Saigal, S.; Saraf, N.; Soin, A.S.; Devarbhavi, H.; Kim, D.J.; Dhiman, R.K.; Duseja, A.; Taneja, S.; Eapen, C.E.; Goel, A.; Ning, Q.; Chen, T.; Ma, K.; Duan, Z.; Yu, C.; Treeprasertsuk, S.; Hamid, S.S.; Butt, A.S.; Hamid, S.S.; Butt, A.S.; Jafri, W.; Shukla, A.; Saraswat, V.; Tan, S.S.; Sood, A.; Midha, V.; Goyal, O.; Ghazinyan, H.; Arora, A.; Hu, J.; Sahu, M.; Rao, P.N.; Lee, G.H.; Lim, S.G.; Lesmana, L.A.; Lesmana, C.R.; Shah, S.; Prasad, V.G.M.; Payawal, D.A.; Abbas, Z.; Dokmeci, A.K.; Sollano, J.D.; Carpio, G.; Shresta, A.; Lau, G.K.; Fazal Karim, M.; Shiha, G.; Gani, R.; Kalista, K.F.; Yuen, M.F.; Alam, S.; Khanna, R.; Sood, V.; Lal, B.B.; Pamecha, V.; Jindal, A.; Rajan, V.; Arora, V.; Yokosuka, O.; Niriella, M.A.; Li, H.; Qi, X.; Tanaka, A.; Mochida, S.; Chaudhuri, D.R.; Gane, E.; Win, K.M.; Chen, W.T.; Rela, M.; Kapoor, D.; Rastogi, A.; Kale, P.; Rastogi, A.; Sharma, C.B.; Bajpai, M.; Singh, V.; Premkumar, M.; Maharashi, S.; Olithselvan, A.; Philips, C.A.; Srivastava, A.; Yachha, S.K.; Wani, Z.A.; Thapa, B.R.; Saraya, A.; Shalimar; Kumar, A.; Wadhawan, M.; Gupta, S.; Madan, K.; Sakhuja, P.; Vij, V.; Sharma, B.C.; Garg, H.; Garg, V.; Kalal, C.; Anand, L.; Vyas, T.; Mathur, R.P.; Kumar, G.; Jain, P.; Pasupuleti, S.S.R.; Chawla, Y.K.; Chowdhury, A.; Alam, S.; Song, D.S.; Yang, J.M.; Yoon, E.L.; APASL ACLF Research Consortium (AARC) for APASL ACLF working PartyThe first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set up in 2004 on acute-on-chronic liver failure (ACLF) was published in 2009. With international groups volunteering to join, the "APASL ACLF Research Consortium (AARC)" was formed in 2012, which continued to collect prospective ACLF patient data. Based on the prospective data analysis of nearly 1400 patients, the AARC consensus was published in 2014. In the past nearly four-and-a-half years, the AARC database has been enriched to about 5200 cases by major hepatology centers across Asia. The data published during the interim period were carefully analyzed and areas of contention and new developments in the field of ACLF were prioritized in a systematic manner. The AARC database was also approached for answering some of the issues where published data were limited, such as liver failure grading, its impact on the 'Golden Therapeutic Window', extrahepatic organ dysfunction and failure, development of sepsis, distinctive features of acute decompensation from ACLF and pediatric ACLF and the issues were analyzed. These initiatives concluded in a two-day meeting in October 2018 at New Delhi with finalization of the new AARC consensus. Only those statements, which were based on evidence using the Grade System and were unanimously recommended, were accepted. Finalized statements were again circulated to all the experts and subsequently presented at the AARC investigators meeting at the AASLD in November 2018. The suggestions from the experts were used to revise and finalize the consensus. After detailed deliberations and data analysis, the original definition of ACLF was found to withstand the test of time and be able to identify a homogenous group of patients presenting with liver failure. New management options including the algorithms for the management of coagulation disorders, renal replacement therapy, sepsis, variceal bleed, antivirals and criteria for liver transplantation for ACLF patients were proposed. The final consensus statements along with the relevant background information and areas requiring future studies are presented here.Item Predicting acute liver failure in dengue Infection(American Gastroenterological Association(AGA) Institute, Published by Elsevier Inc., 2013) Ranawaka, C.; Niriella, M.A.; Kumarasena, R.S.; Miththinda, J.K.N.D.; de Silva, A.P.; Premaratna, R.; de Silva, H.J.BACKGROUND: Dengue infections (DI) can range from being asymptomatic to severe illness. Unusual manifestations such as encephalitis, myocarditis, and acute liver failure (ALF) have been recognized. ALF is uncommon, but has a poor prognosis. The aim of this study was to identify predictors of ALF in DI. METHODS: Serologically confirmed patients with DI who were admitted to hospital from January 2009 to March 2010 were included. Patients consisted of direct admissions as well as referrals, some with deranged liver functions. Data was obtained from patient records. Clinical details and serum biochemistry was evaluated for up to five days from onset of illness. ALF in DI was defined as evidence of coagulation abnormality [International normalised ratio (INR) ≥ 1.5], and any degree of mental alteration (encephalopathy) in a patient without pre-existing cirrhosis. RESULTS: Out of 240 patients [57.7% male, 42.3% female; mean age 35.6 years (SD 15.4 years)], 164 had dengue with warning signs, 27 had dengue without warning signs and 49 had severe dengue. 15/49 severe dengue patients had profound shock. Abdominal pain, persistent nausea and vomiting (PNV), bleeding, hepatomegaly and ascites were present in 125, 92, 39, 129 and 28 cases respectively. Elevated aspartate aminotransferase (AST), serum bilirubin (SB), alkaline phosphatase (ALP) and gamma glutamyl transpeptide (GGT) were observed in 208, 20, 18 and 60 patients respectively. Of the 240 patients 41 had AST .1000 IU/ml (this included 4/ 15 with profound shock). 16/41 patients with AST .1000 IU/ml, including 4 with profound shock, developed ALF while none with AST ,1000 IU/ml developed ALF. In patients with AST .1000 IU/ml, presence of 2 or 3 of elevated SB, elevated ALP or PNV predicted the development of ALF with 93.8% sensitivity, 98.7% specificity, 83.3% positive predictive value and 99% negative predictive value (Fisher's exact test). CONCLUSIONS: Dengue patients with AST,1000 IU/ml are not at risk of developing ALF. Patients with AST .1000 (regardless of presence or absence of profound shock), with 2 or 3 of elevated SB, elevated ALP or PNV seem to be at risk of developing ALF. These findings need to be validated in a larger cohort of patients.
