2023 Update of Indian National Association for Study of the Liver Consensus on Management of Intermediate and Advanced Hepatocellular Carcinoma: The Puri III Recommendations

Hepatocellular carcinoma (HCC) presents significant treatment challenges despite considerable advancements in its management. The Indian National Association for the Study of the Liver (INASL) first published its guidelines to aid healthcare professionals in the diagnosis and treatment of HCC in 2014. These guidelines were subsequently updated in 2019. However, INASL has recognized the need to revise its guidelines in 2023 due to recent rapid advancements in the diagnosis and management of HCC, particularly for intermediate and advanced stages. The aim is to provide healthcare professionals with evidence-based recommendations tailored to the Indian context. To accomplish this, a task force was formed, and a two-day round table discussion was held in Puri, Odisha. During this event, experts in their respective fields deliberated and finalized consensus statements to develop these updated guidelines. The 2023 INASL guidelines offer a comprehensive framework for the diagnosis, staging, and management of intermediate and advanced HCC in India. They represent a significant step forward in standardizing clinical practices nationwide, with the primary objective of ensuring that patients with HCC receive the best possible care based on the latest evidence. The guidelines cover various topics related to intermediate and advanced HCC, including biomarkers of aggressive behavior, staging, treatment options, and follow-up care.

Overview of hepatocellular carcinoma: from molecular aspects to future therapeutic options

Hepatocellular carcinoma (HCC) is the seventh most highly prevalent malignant tumor globally and the second most common cause of mortality. HCC develops with complex pathways that occur through multistage biological processes. Non-alcoholic fatty liver disease, metabolic-associated fatty liver disease, alcoholic liver disease, autoimmune hepatitis, hepatitis B, and hepatitis C are the causative etiologies of HCC. HCC develops as a result of epigenetic changes, protein-coding gene mutations, and altered signaling pathways. Biomarkers and potential therapeutic targets for HCC open up new possibilities for treating the disease. Immune checkpoint inhibitors are included in the treatment options in combination with molecular targeted therapy.

Pediatric combined living donor liver and kidney transplantation for primary hyperoxaluria type 2

We report the case of a 12-year-old boy with primary hyperoxaluria type 2 (PH2) presenting with end-stage renal disease and systemic oxalosis who underwent a combined living donor liver and kidney transplant from 3 donors, 1 of whom was a heterozygous carrier of the mutation. Plasma oxalate and creatinine levels normalized immediately following the transplant and remain normal after 18 months. We recommend combined liver and kidney transplantation as the preferred therapeutic option for children with primary hyperoxaluria type 2 with early-onset end-stage renal disease.

Novel radiological technique to recognize acute liver failure caused by yellow phosphorous containing rodenticides

Yellow phosphorous rodenticide (YPR) poisoning is the commonest cause for acute liver failure (ALF) in southern and western India. Due to medicolegal issues, history of YPR ingestion may not be available. As early recognition of YPR poisoning is important and there are no specific biochemical assays, other early predictors to identify this entity is necessary. We evaluated the diagnostic role of plain computed tomography (CT) in identifying YPR-induced ALF. All patients admitted to the liver unit with a diagnosis of ALF underwent a plain CT scan abdomen. Demographic details, clinical history, laboratory parameters, liver attenuation index (LAI) calculated on CT scan, treatment details, need for liver transplantation and clinical outcome were analyzed. Parameters for YPR-induced ALF (ALF-YPR) and other causes (ALF-OTH) were compared. Ability of LAI to distinguish ALF-YPR and ALF-OTH was analyzed using receiver operating characteristic (ROC) curve analysis. Twenty-four patients (15 female [62.5%]) were included in the study. Thirteen patients (54%) had YPR poisoning, while the rest formed the ALF-OTH group (11,46%). ALF-YPR patients had higher transaminase levels, lower peak serum bilirubin levels. ALF-YPR livers had significantly lower LAI as compared to ALF-OTH (- 30 vs. - 8, p = 0.001). On ROC curve analysis, an LAI greater than - 18 ruled out YPR as the cause for ALF with 91% sensitivity and 85% specificity. On regression analysis, LAI was the only independent factor predicting ALF-YPR (odds ratio - 0.86, [0.76, 0.96] p = 0.008). Our data shows that LAI on plain abdominal CT scan can be used to quickly recognize ALF-YPR in unclear cases so that necessary treatment protocol can be activated, or patient transfer arranged. Our analysis shows that an LAI greater than - 18 can reliably rule out YPR ingestion as the cause for ALF.

Study protocol for The GOAL Trial: comprehensive geriatric assessment for frail older people with chronic kidney disease to increase attainment of patient-identified goals-a cluster randomised controlled trial

BACKGROUND

An increasing number of older people are living with chronic kidney disease (CKD). Many have complex healthcare needs and are at risk of deteriorating health and functional status, which can adversely affect their quality of life. Comprehensive geriatric assessment (CGA) is an effective intervention to improve survival and independence of older people, but its clinical utility and cost-effectiveness in frail older people living with CKD is unknown.

METHODS

The GOAL Trial is a pragmatic, multi-centre, open-label, superiority, cluster randomised controlled trial developed by consumers, clinicians, and researchers. It has a two-arm design, CGA compared with standard care, with 1:1 allocation of a total of 16 clusters. Within each cluster, study participants ≥ 65 years of age (or ≥ 55 years if Aboriginal or Torres Strait Islander (First Nations Australians)) with CKD stage 3-5/5D who are frail, measured by a Frailty Index (FI) of > 0.25, are recruited. Participants in intervention clusters receive a CGA by a geriatrician to identify medical, social, and functional needs, optimise medication prescribing, and arrange multidisciplinary referral if required. Those in standard care clusters receive usual care. The primary outcome is attainment of self-identified goals assessed by standardised Goal Attainment Scaling (GAS) at 3 months. Secondary outcomes include GAS at 6 and 12 months, quality of life (EQ-5D-5L), frailty (Frailty Index - Short Form), transfer to residential aged care facilities, cost-effectiveness, and safety (cause-specific hospitalisations, mortality). A process evaluation will be conducted in parallel with the trial including whether the intervention was delivered as intended, any issue or local barriers to intervention delivery, and perceptions of the intervention by participants. The trial has 90% power to detect a clinically meaningful mean difference in GAS of 10 units.

DISCUSSION

This trial addresses patient-prioritised outcomes. It will be conducted, disseminated and implemented by clinicians and researchers in partnership with consumers. If CGA is found to have clinical and cost-effectiveness for frail older people with CKD, the intervention framework could be embedded into routine clinical practice. The implementation of the trial's findings will be supported by presentations at conferences and forums with clinicians and consumers at specifically convened workshops, to enable rapid adoption into practice and policy for both nephrology and geriatric disciplines. It has potential to materially advance patient-centred care and improve clinical and patient-reported outcomes (including quality of life) for frail older people living with CKD.

“Achieving Optimal Clinical Outcomes in Autologous Fat Grafting: A Systematic Review of Processing Techniques”

BACKGROUND

Autologous fat grafting (AFG) is a versatile technique in reconstructive and cosmetic surgery. Graft processing is a key source of variability resulting in unreliable clinical outcomes, with no consensus on the optimal methodology. This systematic review identifies the evidence base supporting different processing paradigms.

METHODS

A systematic literature search was conducted using the PubMed, Scopus and The Cochrane Foundation databases. Studies comparing AFG processing methods and reporting long-term patient outcomes were identified.

RESULTS

Twenty-four studies (2413 patients) were identified. Processing techniques evaluated included centrifugation, decantation, washing, filtration, gauze rolling, as well as commercial devices and adipose-derived stem/stromal cell (ASC) enrichment methods. Objective volumetric and subjective patient-reported outcomes were discussed. There was a variable reporting of complications and volume retention rates. Complications were infrequent; palpable cysts (0-20%), surgical-site infections (0-8%) and fat necrosis (0-58.4%) were the most reported. No significant differences in long-term volume retention between techniques were found in AFG in the breast. In head and neck patients, greater volume retention was documented in ASC enrichment (64.8-95%) and commercial devices (41.2%) compared to centrifugation (31.8-76%).

CONCLUSIONS

Graft processing through washing and filtration, including when incorporated into commercial devices, results in superior long-term outcomes compared to centrifugation and decantation methods. ASC enrichment methods and commercial devices seem to have superior long-term volume retention in facial fat grafting.

Right Lobe Living Donor Hepatectomy in the Setting of Agenesis of Gall Bladder - A Case Report

Agenesis of Gall Bladder (AGB) is a rare congenital anomaly with only around 500 cases reported so far. The condition may be associated with other biliary anomalies and present diagnostic and technical challenges during hemi hepatectomy which can be surmounted with careful planning. Live donor hepatectomy in the setting of AGB has not been reported before. We report a case of AGB in a potential living donor and highlight the technical modifications used to perform a safe right hepatectomy in this donor.

First Report of a Paediatric Collision Tumour in the Liver Recognised After Liver Transplantation: Blissful Ignorance Has Benefits!

Liver tumours are uncommon in the paediatric population, constituting 1-2 % of all paediatric tumours and 4% of all paediatric liver tumours. Hepatoblastoma followed by hepatocellular carcinoma is the most common tumours in this age group. Simultaneous development of two discrete liver tumours of distinct histologies (collision tumour) has been occasionally reported in adults but never in children. We hereby present the first reported case of hepatic collision tumours (hepatocellular carcinoma and cholangiocarcinoma) in the explant liver of a child who underwent living donor liver transplantation for end-stage liver disease and severe hepatopulmonary syndrome. The manuscript describes the clinical, radiological and histopathological findings of this case and also highlights the dilemma associated with management of this case had the diagnosis been made in the preoperative setting and also about the proposed management plan for this case in the postoperative period.

When Push Comes to Shove! Emergency ABO-Incompatible Pediatric Living Donor Liver Transplant for Acute Wilson's Disease

ABO-incompatible living donor liver transplantation (ABOi-LDLT) is on the rise as a viable option in countries with limited access to deceased donor grafts. While reported outcomes of ABOi-LT in children are similar to ABO- Compatible liver transplant (ABOc-LT), most children beyond 1-2 years of age will need desensitization to overcome the immunological barrier of incompatible blood groups. The current standard protocol for desensitization is Rituximab that targets B lymphocytes and is given 2-3 weeks prior to LT. However, this timeline may not be feasible in children requiring emergency LT for acute liver failure (ALF) or acute-on-chronic liver failure (ACLF). In this emergency situation of ABOi-LT, a safe multipronged approach may be an acceptable alternative solution. We report a child with acute Wilson's disease with rapidly deteriorating liver function who underwent a successful ABOi-LDLT using a rapid desensitization protocol.

Living-Donor Liver Transplantation for Late-Onset Lysosomal Acid Lipase Deficiency

Late-onset liposomal acid lipase deficiency (LAL deficiency), previously known as Cholesteryl ester storage disease (CESD) is a rare genetic lysosomal storage disorder caused by deficiency of lysosomal acid lipase (LAL) due to mutations in the LIPA gene. LAL deficiency is a systemic disease that leads to the accumulation of fat and inflammation in the liver, premature atherosclerosis and gastrointestinal disease. Most of the patients require liver transplantation due to decompensated cirrhosis. Enzyme replacement therapy has been approved and is available in many countries. Here we describe a 16-year-old patient who was diagnosed to have late-onset LAL deficiency when he presented to us with ESLD. Subsequently, he underwent a living-donor liver transplant (LDLT) successfully. We discuss the ethical dilemmas in considering LDLT for LAL deficiency.

Liver Transplant Society of India Guidelines for Liver Transplant During COVID-19 times

Coronavirus disease-2019 (COVID-19) pandemic has affected liver transplantation in many ways. There is risk of infection to the transplant recipients; and COVID-19 is associated with significant risk of mortality in patients on wait list. The Liver Transplant Society of India (LTSI) has prepared guidelines regarding selection of adult and pediatric patients for liver transplantation, transplant for acute liver failure, use of deceased donor organs, transplant techniques and minimally invasive donor hepatectomy, pre- and postsurgery testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related coronavirus disease 2019 in donors and recipients, role of COVID-19 antibody testing, shifting of recipients from COVID-19 to non-COVID-19 areas after recovery, isolation policy of team members exposed to COVID-19 patients, drug therapy of proven or suspected COVID-19 infection early posttransplant, care of SARS-CoV-2 positive donors and recipients and a separate COVID-19 consent for surgery.

Delayed Expulsion of biliary cast after hepaticojejunostomy for post-liver transplantation biliary stricture-better cut than canulate?

BACKGROUND

Biliary strictures after living donor liver transplantation (LDLT) are a significant cause of post-transplant morbidity. Endoscopic therapy is usually the first choice of treatment though surgical treatment may provide better biliary drainage.

METHODS

We report a case of LDLT performed in a child for acute liver failure who developed an anastomotic biliary stricture with biliary cast formation. We performed a Roux en Y hepaticojejunostomy to treat the stricture.

RESULTS

Allograft function improved after surgery with no further episodes of cholangitis. Two months after the surgery, the child passed a large biliary cast in the stools. This reiterates the advantage of wide biliary drainage provided through surgical therapy.

CONCLUSIONS

Surgery for biliary strictures following LDLT may provide superior long term biliary drainage- especially when biliary casts are present.

The oncoprotective fever hypothesis: Have antibiotics, antimalarials and antipyrectics contributed to the global rise in cancer over the past century?

The adaptive and therapeutic nature of fever has been recognized for centuries and both local and systemic thermotherapy are now used to enhance the effectiveness of both chemotherapy and radiation therapy for cancer. We propose that the success of antiseptic, antibiotic, antipyretic and antimalarial strategies and medications over the past century and a half may have had the unintended effect of releasing precancerous growths and neoplastic foci from the inhibitory effects of intermittent fever. This may be a previously unrecognized factor in the overall rise in cancer rates in the late 19th and early 20th centuries.

The role of cardiovascular magnetic resonance imaging with T1 and T2 mapping in sudden cardiac death survivors

Background

Sudden cardiac death (SCD) in the adult population is poorly studied, although determining its etiology is crucial for management and prognosis [1]. Cardiovascular magnetic resonance imaging (CMR) is being increasingly utilized in SCD survivors [1,2]. The role of late gadolinium enhancement (LGE) imaging in patients with recent SCD and no significant coronary artery disease (CAD) is well established, but there is no data on the additive role of T1 and T2 mapping [1–3].

Purpose

This is a retrospective study to assess the role of CMR including T1 and T2 mapping in SCD survivors.

Methods

Between 01/2016 and 12/2019, we retrospectively analyzed patients who underwent CMR on a Siemens Magnetom Avanto 1.5 T scanner within 4 weeks of SCD. CMR protocol included cine imaging, T1 and T2 mapping, and LGE imaging. Native and post-contrast myocardial T1 values were measured within the septum on the mid short axis (SAX) and extracellular volume fraction was calculated using the standard formula. T2 values were measured in six mid segments on the mid SAX map. Additional measurements were performed if long axis T2 maps were available. Clinical data, electrocardiography (ECG), transthoracic echocardiography (TTE), coronary computed tomography angiography (CCTA), and left heart catheterization (LHC) were reviewed from the electronic health record. An ischemic evaluation was performed in 33 (94%) of patients.

Results

A total of 35 patients who underwent CMR for SCD were included for analysis (mean age 46.9±14.1 years; 20 (57%) male). SCD etiology was established based on clinical data, ECG, TTE, CCTA, and LHC in 9 (26%) patients. CMR provided the most probable SCD etiology in an additional 20 (57%) patients with T1 and T2 mapping abnormalities seen in 18 (51%) patients. Diagnoses determined by CMR included myocarditis (35%), hypertrophic cardiomyopathy (CMP) (20%), left ventricular non-compaction CMP (15%), dilated CMP (10%), takotsubo CMP (5%), and myocardial infarction with non-obstructive CAD (15%) (Table, Figure). Elevated native T1 was seen in 15 (43%) (mean T1 1069±60 ms; site specific normal <1080 ms), elevated ECV in 16 (46%) (30±7%; site specific normal <29%), and elevated native T2 in 22 (63%) patients (65±10 ms; site specific normal <60 ms). LGE was present in 31 (89%) patients. The etiology of SCD remained unknown in 6 (17%) patients despite extensive testing including CMR.

Conclusions

CMR has significant diagnostic and prognostic value in assessing SCD etiology compared to non-CMR based evaluation. Myocarditis is a common underdiagnosed cause of SCD in adult patients well seen in a CMR protocol with T1 and T2 mapping. Myocardial inflammation monitoring in SCD survivors with serial CMRs using T1 and T2 mapping could influence clinical decision making by justifying pharmacotherapy modification and timing of ICD implantation. To conclude, CMR with T1 and T2 mapping provides high diagnostic yield in the investigation of SCD etiology.

Management of portal hypertensive upper gastrointestinal bleeding: Report of the Coorg Consensus workshop of the Indian Society of Gastroenterology Task Force on Upper Gastrointestinal Bleeding

Portal hypertensive bleeding is a major complication of portal hypertension (PHT) with high morbidity and mortality. A lot of advances have been made in our understanding of screening, risk stratification, and management strategies for portal hypertensive bleeding including acute variceal bleeding leading to improved overall outcomes in patients with PHT. A number of guidelines on variceal bleeding have been published by various societies in the past few years. The Indian Society of Gastroenterology (ISG) Task Force on Upper Gastrointestinal Bleeding (UGIB) felt that it was necessary to bring out a standard practice guidance document for the use of Indian health care providers especially physicians, gastroenterologists, and hepatologists. For this purpose, an expert group meeting was convened by the ISG Task Force to deliberate on this matter and write a consensus guidance document for Indian practice. The delegates including gastroenterologists, hepatologists, radiologists, and surgeons from different parts of the country participated in the consensus development meeting at Coorg in 2018. A core group was constituted which reviewed all published literature on portal hypertensive UGIB with special reference to the Indian scenario and prepared unambiguous statements on different aspects for voting and consensus in the whole group. This consensus was produced through a modified Delphi process and reflects our current understanding and recommendations for the diagnosis and management of portal hypertensive UGIB in Indians. Intended for use by the health care providers especially gastroenterologists and hepatologists, these consensus statements provide an evidence-based approach to risk stratification, diagnosis, and management of patients with portal hypertensive bleeding.

Rodenticide ingestion is an important cause of acute hepatotoxicity in Tamil Nadu, southern India

BACKGROUND AND AIM

Though rodenticidal hepatotoxicity is reported from India, there is no systematic study to assess its magnitude. This study aimed to assess exposure to rodenticide as a risk factor for acute hepatotoxicity in Tamil Nadu, India.

METHODS

We retrospectively analyzed acute hepatotoxicity caused by ingestion of hepatotoxin or potentially hepatotoxic drug overdose across 15 hospitals in 6 districts of Tamil Nadu from 1 January 2019 to 30 June 2019. Study exclusion criteria were idiosyncratic drug-induced liver injury and chronic liver diseases.

RESULTS

Of the 702 patients, 685 gave history of consuming rodenticide; hepatotoxicity in the other patients resulted from paracetamol overdose (n=10) and due to other drugs (n=7); 97% patients had a suicidal intent. Of 671 patients with complete data, ratio of number of patients with hepatotoxicity due to rodenticide to paracetamol overdose was 450:6 (i.e. 75:1). The 451 rodenticidal hepatotoxicity patients (255 males, 75% were 15-34 years old) underwent conservative management (n=396), plasma exchange (n=54) and plasma exchange followed by liver transplant (n=1); 159 patients (35%) had poor outcome (131 died, 28 discharged in moribund state). Based on our observations, we estimate a case burden of 1584 rodenticidal hepatotoxicity patients (95% CI: 265-6119) with poor outcome in 554 patients in Tamil Nadu from January 2019 to June 2019. Population attributable risk for rodenticide as cause of hepatotoxicity was 22.7%.

CONCLUSION

Rodenticide ingestion was an important cause of acute hepatotoxicity in Tamil Nadu. Most patients were young and one-third had poor outcome. Public health interventions are needed to address this.

Liver Transplantation Society of India Guidelines for the Management of Acute Liver Injury Secondary to Yellow Phosphorus-Containing Rodenticide Poisoning Using the Modified Delphi Technique of Consensus Development

BACKGROUND

Acute liver failure caused by the ingestion of yellow phosphorus-containing rodenticide has been increasing in incidence over the last decade and is a common indication for emergency liver transplantation in Southern and Western India and other countries. Clear guidelines for its management are necessary, given its unpredictable course, potential for rapid deterioration and variation in clinical practice.

METHODS

A modified Delphi approach was used for developing consensus guidelines under the aegis of the Liver Transplantation Society of India. A detailed review of the published literature was performed. Recommendations for three areas of clinical practice, assessment and initial management, intensive care unit (ICU) management and liver transplantation, were developed.

RESULTS

The expert panel consisted of 16 clinicians, 3 nonclinical specialists and 5 senior advisory members from 11 centres. Thirty-one recommendations with regard to criteria for hospital admission and discharge, role of medical therapies, ICU management, evidence for extracorporeal therapies such as renal replacement therapy and therapeutic plasma exchange, early predictors of need for liver transplantation and perioperative care were developed based on published evidence and combined clinical experience.

CONCLUSION

Development of these guidelines should help standardise care for patients with yellow phosphorus poisoning and identify areas for collaborative research.

Serum C-reactive protein and neutrophil-to-lymphocyte ratio as predictors of survival in cirrhotic patients with systemic inflammatory response syndrome and bacterial infection

BACKGROUND

Cirrhotic patients are prone to infections due to underlying immune dysfunction in them. We aimed to study the role of inflammatory markers, serum C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR), in predicting infection, blood culture positivity, and short-term (1 month) mortality in hospitalized cirrhotic patients.

METHODS

This prospective study was done over a period of 14 months (October 2017 to November 2018). Patient data included age, gender, etiology of cirrhosis, reason for admission, and comorbidity. Laboratory tests included blood chemistry and blood cell counts, and blood and urine culture. The specific tests included were CRP and NLR. Survival of patients in the following 1 month was noted. Area under receiver operating characteristic curve (AUROC), sensitivity, specificity, predictive values, diagnostic accuracy were calculated and logistic regression analysis performed. A p-value < 0.05 was considered significant.

RESULTS

Two hundred and eight patients formed the study cohort. The median age was 51.5 years and male predominance was noted. Alcohol-related liver disease (49%) was the commonest etiology. The infection rate was 62%, culture positivity was 58.5%, and mortality was 30.8%. NLR and CRP were significantly higher in those with documented infection (culture positive or negative) and among nonsurvivors. Optimal cutoffs for NLR and CRP to predict infection were 5.86 and 33.7, respectively. The risk of having an infection was 7.5 times and about 15 times if NLR and CRP were above the cutoffs. The risk of 1-month mortality was 2-3 times higher if patients had NLR and CRP above the cutoffs. The combination of NLR and CRP (≥ 5.86 and ≥ 33.7, respectively) increased specificity and diagnostic accuracy for infection.

CONCLUSION

NLR and CRP were independently good predictors of infection and 1-month survival among the patients with cirrhosis of liver included in this study.

Evaluation of Smear Layer Removal and Antimicrobial Efficacy of HybenX Against Enterococcus Faecalis Biofilm

To evaluate the antibacterial efficacy of HybenX, an endodontic irrigant against Enterococcus faecalis biofilm and determine its efficacy in removal of smear layer. Forty root canals were inoculated with E. faecalis for three weeks, divided into 4 groups and irrigated with: Group1: 5 ml 2.5% sodium hypochlorite; Group2: 5 ml 2% chlorhexidine gluconate; Group3: 5 ml HybenX; Group4: 5 ml distilled water (control). Dentin shavings were collected and plated on agar plates, followed by colony forming unit (CFU) determination. For smear layer removal examination, 30 single rooted teeth were instrumented and divided into 3 groups and treated with: GroupI: 5 ml of 17% EDTA; GroupII:5 ml of HybenX; and GroupIII: 5 ml of distilled water. Samples were then subjected to SEM examination. All irrigants showed a significant reduction in CFUs compared to the control group (P⟨ .001), but none compared to each other. Regarding smear layer removal in the apical third, EDTA removed smear layer more effectively than HybenX (P = .014). HybenX demonstrated good antimicrobial efficacy against E. faecalis biofilm and removed the smear layer effectively in coronal and middle third of the root canal system. HybenX can be considered as a promising irrigating agent in root canal treatment of infected teeth.

Role of therapeutic plasma exchange in acute liver failure due to yellow phosphorus poisoning

BACKGROUND

Therapeutic plasma exchange (TPE) has been utilized in various liver disorders. There is limited data on the efficacy of TPE in patients with acute liver failure (ALF).

METHODS

Study group consisted of patients who underwent TPE for ALF due to yellow phosphorous poisoning (YPP) between 2015 and 2019. Demographic data and biochemical parameters were recorded before and after TPE. Overall survival and transplant-free survival (based on King's College Hospital Criteria [KCHC]) were analyzed.

RESULTS

Forty-three patients underwent TPE for ALF due to YPP. Most of them were young males. Overall survival was 34 (79.06%). In our study population, 20 patients fulfilled KCHC (Group A) and 23 did not fulfill KCHC (Group B). Both the groups showed significant improvement in alanine aminotransferase, aspartate aminotransferase, and international normalized ratio (INR) after TPE (p < 0.05). In Group B, there was significant improvement in ammonia after TPE (p < 0.05) and all 23 patients (100%) survived after TPE. In Group A, 4 underwent liver transplantation (LT), 7 survived without LT, and the remaining 9 died without LT. Mean survival after completing TPE was 41.2 ± 44.5 days in Group A and 90 days in Group B. This difference was statistically significant (p = 0.001). There was statistically significant difference in post-TPE values of INR (p = 0.012) and ammonia (p = 0.011) between non-survivors and survivors. Adverse events such as hypotension (11.62%) and minor allergic reaction (4.65%) were managed conservatively.

CONCLUSION

TPE is an effective procedure in ALF due to YPP, not fulfilling KCHC for LT. In KCHC fulfilled group, though it shows LT-free survival benefit, there is requirement of prospective, large volume, multi-center study to assess its efficacy.

In Vitro Evaluation of Substantivity, Staining Potential, and Biofilm Reduction of Guava Leaf Extract Mouth Rinse in Combination with its Anti-Inflammatory Effect on Human Gingival Epithelial Keratinocytes

This study aimed to assess the biofilm reduction, staining potential, and cytotoxicity of guava extract mouth rinse compared to chlorhexidine (CHX). Substantivity, staining, and antibiofilm potential were investigated by spectrophotometry, colony-forming units, and luminosity color meter, respectively. The cell viability assay was conducted using a colorimetric assay to determine nontoxic levels of guava (0.15%) and CHX in human gingival epithelial keratinocytes (HGEK-16). Cells were treated with lipopolysaccharides (LPS, 1μg/mL) and guava to assess inflammatory gene expression levels of interleukin-β1, tumor necrosis factor-α, and Prostaglandin E2. A scratch wound healing assay investigated the effects of guava on cell migration. The teeth coated in guava mouth rinse displayed 19.4% higher substantivity compared to CHX (0.2%), and the anti-biofilm reduction was observed with both guava and CHX mouth rinses (P < 0.05). The overall discoloration changes were higher with CHX and distilled water compared to guava. Also, guava significantly enhanced HGEK-16 cell viability (P < 0.05), and IL-β1, TNFα and PGE2 expression presented a 0.6-fold decrease when exposed to guava and LPS (P < 0.05). The present study showed that guava mouth rinse fulfilled the requirement for an effective and useful oral care product with desirable substantivity and anti-biofilm action. In addition, guava reduced the inflammation response in HGEK-16 and may be a potential oral rinse for oral anti-inflammatory therapies.

Scoring Systems that Predict Mortality at Admission in End-stage Liver Disease

Background

Various scoring systems have been developed to assess the severity and survival in end-stage liver disease.

Aim of the study

Prospective study to compare and analyze the efficacy of scoring systems in predicting mortality in ESLD patients who present with cirrhosis specific complications to the emergency room.

Materials and methods

This prospective, single point study was conducted over a two year period from September 2014 to August 2016 among 162 ESLD patients seeking admission to the emergency unit of Gleneagles Global Health City, Chennai. Baseline investigations incorporated hemogram, liver biochemical parameters, coagulation parameters (PT/INR), serum creatinine, serum electrolytes and blood gas analysis, to calculate the CTP score, MELD, MELD-Na, MESO, iMELD, Updated MELD, UKELD, SOFA and APACHE II. Comparison of MELD snd non MELD scores were done between survivors and nonsurvivors. The mortality rate for the same admission was calculated.

Results

Of the 162 patients requiring emergency admision, 148 were men (91.4%). The median age of patients was 56 years (range 25–75 years). The cause for liver cirrhosis was alcohol followed by nonalcoholic steatohepatitis and hepatitis B. The indications for emergency admissions were fever, tense ascites, reduced urine output and altered sensorium. Thirty patients (18.5%) expired during the same admission. The predictive accuracy of all scores for predicting mortality by ROC curves was between 0.7 and 0.8 (p < 0.05).

Conclusion

Although, all scores appear to be equally good, simple scores like CTP and MELD is all that is required to ascertain the prognosis of patients seeking emergency admission.

Explant liver evaluation decodes the mystery of cryptogenic cirrhosis!

Background and Aim

To determine the concordance of liver explants with the pretransplant diagnosis.

Methods

This was a retrospective analysis of 251 liver explants. Patient information included demography, comorbidity, and etiological diagnosis. Final diagnosis was based on morphological and histological findings. For non‐alcoholic steatohepatitis (NASH) and cryptogenic cirrhosis, we investigated comorbid states such as obesity, hypertension, and diabetes. Chi square test and Cohen's Kappa value were used. A P value of <0.05 was considered significant.

Results

A total of 192 patients (76.5%) were males. A significant concordance of explant diagnosis with pretransplant diagnosis was present in 225 (89.6%) patients. It was 100% for alcohol‐related disease, hepatitis B, hepatitis C, autoimmune (AI) liver disease, biliary cirrhosis, and Budd–Chiari syndrome. Of 37 patients with a pretransplant diagnosis of cryptogenic cirrhosis, major discordance was observed in 23 (62.1%). On explant, seven patients each had hemochromatosis 5 (13.5%), AI hepatitis, and NASH (18.9%); two had noncirrhotic fibrosis (5.4%); and one each had Wilson's disease and congenital hepatic fibrosis (2.7%). Of the 20 explants, 3 with pretransplant diagnosis of NASH had a diagnosis of cryptogenic cirrhosis on explant specimens. Cohen's Kappa for the concordance of pretransplant diagnosis and explant diagnosis in NASH and cryptogenic cirrhosis patients was 0.75 and 0.47, respectively. An incidental hepatocellular carcinoma was picked up in 16 explants, and 18 had granulomas.

Conclusion

Concordance between pretransplant and explant diagnosis is lower for NASH and cryptogenic cirrhosis. The true prevalence of cryptogenic cirrhosis in our study was 5.6%.

Prevalence and clinical presentation of cirrhotic cardiomyopathy: A single centre experience from southern India

BACKGROUND

There are scanty data from India on the prevalence and clinical profile of cirrhotic cardiomyopathy (CCM).

AIM

To identify the prevalence and clinical presentation of CCM in patients with liver cirrhosis.

METHODS

Five hundred and eighty-six patients with liver cirrhosis were recruited based on inclusion criteria and evaluated for cardiac parameters using electrocardiography, 2-dimensional echocardiography, dobutamine stress test and coronary angiography as needed. Baseline demographic data, liver biochemistry, endoscopic and radiological findings were recorded in all the patients. Appropriate statistical analyses were performed.  RESULTS: Four thousand eight hundred and seventy-seven patients with liver disease were registered during the study period. Five hundred and eighty-six cirrhotic patients had cardiac evaluation as per the study protocol. One hundred fifty-nine had coronary artery disease and were excluded. One hundred and ninety-eight of 427 remaining patients (46.4%) had CCM. The median age of patients with CCM was higher compared with those without CCM (52 years vs. 46 years; p-value < 0.00001). Likewise, cirrhosis-related complications ([isolated or in combination], lower pulse rate [< 60/min] and prolonged corrected QT interval [QTc]; p<0.00001) were more frequent in patients with CCM. After excluding known risk factors for CCM such as alcohol, diabetes, hypothyroidism, hypertension, the true prevalence of CCM was 8.2% (48 out of 586). Hepatotropic viral infections (p 0.03) and prolonged QTc (p 0.0004) were commoner in CCM.

CONCLUSION

Prevalence of CCM in our setting is 33.8%. CCM is commoner in males and is independent of the etiology of cirrhosis, comorbidity and severity of liver disease. Diastolic dysfunction and prolonged QTc interval are common in CCM.

Prevalence of Minimal Hepatic Encephalopathy in Patients With Liver Cirrhosis: A Cross-Sectional, Clinicoepidemiological, Multicenter, Nationwide Study in India: The PREDICT Study

BACKGROUND

The study aimed at assessing the prevalence and clinical profile of minimal hepatic encephalopathy (MHE) in patients with cirrhosis using neuropsychological assessment and at understanding the management practices of MHE in the Indian clinical setting.

METHODS

This cross-sectional, clinicoepidemiological study conducted at 20 sites enrolled liver cirrhosis patients with Grade 0 hepatic encephalopathy according to West-Haven Criteria. Patients were subjected to mini-mental state examination and those with a score of ≥24 were assessed using psychometric hepatic encephalopathy score. Short Form-36 questionnaire was administered to assess the impact on health-related quality of life.

RESULTS

Of the 1260 enrolled patients, 1114 were included in the analysis. The mean age was 49.5 years and majority were males (901 [81%]). The prevalence of MHE was found to be 59.7% (665/1114) based on the psychometric hepatic encephalopathy score of ≤-5. Alcohol-related liver disease was the most common etiology (482 [43.27%]) followed by viral infection (239 [21.45%]). Past smokers as well as those currently smoking were more likely to have MHE than nonsmokers. A significant association was found between tobacco chewing, smoking, alcohol consumption, diabetes, and the presence of MHE. Multivariable analysis revealed smoking as the only parameter associated with MHE. A total of 300 (26.9%) patients were on prophylaxis with lactulose/lactitol or rifaximin. These patients were less likely to have MHE as compared to those not on prophylaxis (odds ratio, 0.67; 95% confidence interval, 0.50-0.88; P = 0.005).

CONCLUSION

The disease burden of MHE is quite substantial in patients with cirrhosis with no apparent cognitive defect. Smoking, whether past or current, has significant association with the presence of MHE. Although MHE has been shown to adversely affect quality of life, prophylaxis for MHE is not routinely practiced in the Indian setting.The study has been registered under clinical trials registry of India (CTRI/2014/01/004306).

Stauffer’s Syndrome: A Rare Paraneoplastic Syndrome with Renal Cell Carcinoma

An elderly male patient presented with cholestatic jaundice and weight loss. On evaluation, he was found to have left renal mass and hepatomegaly. Diagnosis of Stauffer’s syndrome was confirmed based on his clinical history, biochemical evaluation, and liver biopsy. Resolution of jaundice was noted after removal of the renal mass.

Systematic review of methodologies used to assess mastectomy flap viability

BACKGROUND

Accurate prediction of mastectomy skin flap viability is vital as necrosis causes significant morbidity, potentially compromising results and delaying oncological management. Traditionally assessed by clinical judgement, a more objective evaluation can be provided using intraoperative imaging modalities. This systematic review aimed to compare all intraoperative techniques for assessment of mastectomy flap viability.

METHODS

A systematic literature review was performed using MEDLINE and Embase databases. Primary outcomes reported included specificity, sensitivity and predictive values of each test, and mean rates of mastectomy flap necrosis and reoperation. Secondary outcomes included cost analysis.

RESULTS

Some 18 studies were included. Designs were prospective cohort study (8), retrospective case series (4), prospective case series (3), retrospective case-control study (1), prospective pilot trial (1) and cost analysis study (1). The studies compared indocyanine green angiography (ICGA) (16 studies) and fluorescein dye angiography (FA) (3 studies) with clinical judgement. Sensitivity and specificity were highest for ICGA (5 studies) ranging from 38 to 100 and 68 to 91 per cent respectively. Both methods overpredicted necrosis. Mean rates of flap necrosis and reoperation decreased with ICGA (7·9 and 5·5 per cent respectively) and FA (3 and 0 per cent) compared with clinical judgement (19·4 and 12·9 per cent). Two studies were designed to define numerical parameters corresponding to perfusion using intraoperative techniques. Two studies performed a cost analysis for ICGA; one claimed a cost benefit and the other advocated its use in high-risk patients only.

CONCLUSION

ICGA and FA are potentially useful tools for mastectomy flap assessment. However, the predictive accuracy is subject to the specific settings and model of equipment used. Current recommendations support their use in high-risk patients.

An Insight into Antibiotic Resistance to Bacterial Infection in Chronic Liver Disease

BACKGROUND

End stage liver disease leads to immune dysfunction which predisposes to infection. There has been a rise in antibiotic resistant infections in these patients. There is scanty data f from India or idea regarding the same.

AIM OF THE STUDY

The present study was undertaken to determine the type of infection acquired and the prevalence of antibiotic resistant infections in cirrhotic patients at a tertiary referral center in South India.

MATERIALS AND METHODS

In this retrospective study, all consecutive cirrhotic patients hospitalized between 2011 and 2013 with a microbiologically-documented infection were enrolled. Details of previous admission and antibiotics if received were noted. In culture positive infections, the source of infection (ascites, skin, respiratory tract: sputum/endotracheal tube aspirate, pleural fluid; urine and blood) and microorganisms isolated and their antibiotic susceptibility was noted.

RESULTS

A total of 92 patients had 240 culture positive samples in the study period. Majority were Klebseilla followed by Escherichia coli and Enterococcus in nosocomial and health care associated infections. However, Enteroccocus was followed by E. coli and Klebsiella in community acquired infections. The antibiotic sensitivity pattern was analyzed for the major causative organisms such as E. coli, Klebsiella and Enterococcus. Most common resistant strains were extended spectrum beta lactamase producing enterobacteriacae (ESBL) followed by carbapenemase producing Klebsiella and methicillin resistant Staphylococcus aureus.

CONCLUSION

Noscomial infection is the most common type, with Klebsiella and E. coli and there is significant rise in ESBL producing organism.

Seroprevalence of cytomegalovirus in donors & opportunistic viral infections in liver transplant recipients

Background & objectives:

Opportunistic virus infections are common in liver transplant (LT) recipients. There is a risk of developing infection with cytomegalovirus (CMV) and herpes-related viruses such as herpes simplex virus-1 and 2 (HSV-1 & 2), Epstein-Barr virus (EBV) and Varicella Zoster virus (VZV), reactivation of infection and recurrent infection. This study was conducted to determine CMV seropositivity in donors and its influence on LT recipients and seropositivity of CMV, HSV-1 and 2, EB viral capsid antigen (EBVCA) and VZV in LT recipients and their reactivation.

Methods:

Pre-transplant data for IgG and IgM for CMV (and donor), HSV-1 and -2, EB viral capsid antigen (VCA) and VZV were available for 153 recipients. All recipients were on ganciclovir or valganciclovir prophylaxis for three months after LT. For reactivation rates, findings of post-transplant CMV quantitative reverse transcription polymerase chain reaction (CMV qRT-PCR) assay were associated with pre-transplant serological profile.

Results:

Of the 153 LT recipients, 131 were men (85.6%). The median age of LT was 46 yr (range 9 months-71 yr). Overall exposure to CMV was 71.8 per cent followed by EB VCA (61.4%) and VZV (49.6%). Susceptibility to both HSV-1 and -2 was high across all decades (P<0.001). Seropositivity of CMV in donor was 90.9 per cent (100 out of 110). Post-transplant CMV qRT- PCR was positive in 17 (26.6%; 3 in recipient negative) of 64 samples tested. qRT-PCR assay was positive in one out of four (25%) tested for HSV-1 and nine out of 19 (47.4%) tested for EBV. Two recipients tested for HSV-2 and one for VZV were negative. There were three deaths in recipients (D+ R+) who were also positive for CMV qRT PCR. There was one death due to HSV-1 pneumonia. One patient with EBV reactivation developed post-transplant lymphoproliferative disorder two years after transplant.

Interpretation & conclusions:

Transplant recipient were at highest risk of acquiring HSV-1 and -2 more so for HSV-2. CMV exposure in transplant recipients and donors were very high and at greatest risk for recipient reactivation rate. Despite this, death related to CMV reactivation was low.

Double-blind randomized controlled trial of the routine perioperative use of terlipressin in adult living donor liver transplantation

Perioperative terlipressin (Tp) during living donor liver transplantation (LDLT) has been shown to reduce intraoperative portal pressures and improve renal function. Its role and safety profile have never been evaluated in a double-blind randomized controlled trial (RCT). The aim was to evaluate the hemodynamic effects, clinical benefits, and safety of perioperative Tp infusion in adult LDLT. This was a single-center double-blind RCT. Consenting adults with chronic liver disease and low risk of posttransplant renal dysfunction undergoing their first LDLT were randomized. The study group (terlipressin group [TpG]) received an initial bolus of Tp during surgery followed by a Tp infusion for 72 hours in the postoperative period. The placebo group (PbG) received a saline infusion. The primary endpoint was portal pressure after arterial reperfusion. Multiple intraoperative and postoperative variables served as secondary endpoints. A total of 41 patients were enrolled in the trial (TpG, 21; PbG, 20). There were no significant differences in intraoperative portal pressures, blood loss, fluid requirement, vasopressor requirement, or urine output. Peak intraoperative and end of surgery lactate levels were significantly higher in the Tp group. There was no difference in postoperative liver function tests. Incidence of acute kidney injury as assessed by Risk, Injury, Failure, Loss, and End-Stage Kidney Disease criteria was lower in the Tp group (27% versus 60%; P = 0.04). The TpG had less postoperative ascites, a lower need for percutaneous interventions, and a shorter hospital stay. Incidence of bradycardia requiring pharmacological intervention and withdrawal from study was significantly higher in the TpG. In conclusion, this study has not demonstrated a reduction in postreperfusion portal pressure with Tp. However, Tp infusion reduced postoperative ascitic drain output resulting in less frequent percutaneous interventions and reduced hospital stay. Intraoperative hyperlactatemia and symptomatic bradycardia are major concerns. Its use should be restricted to patients with high-volume ascites, and it needs close monitoring during drug infusion.

HRQOL using SF36 (generic specific) in liver cirrhosis

Health-related quality of life (HRQOL) is influenced by the disease state, associated complications and their management. In patients with liver cirrhosis co-morbidity, severity of liver disease and their complications are likely to affect the QOL. The aim of the study was to determine the factors that are likely to influence the domains of HRQOL using SF-36 in patients with liver cirrhosis. For the study, 149 patients with liver cirrhosis were compared with age-gender matched healthy controls for physical and mental components of SF-36 score and the effects of age, co-morbidity severity of liver disease and complications of liver cirrhosis on HRQOL were assessed using the same questionnaire. Results of the study showed that except for body pain, all the patients had a significantly low individual and composite domain score (p-value <0.0001) compared to age-gender matched controls. Patients below 45 years, Child-Turcotte-Pugh (CTP) C, a high model for end-stage liver disease (MELD) and higher rates of complication had low scores for body pain (KW p <0.005) and those above 55 years, for physical function (p <0.05). Both the physical components had a major impact on mental composite score (MCS) (KW p <0.05). Co-morbidity that included diabetes, hypertension and hypothyroid states in various combinations had no effect on SF-36 scores while co-morbid conditions like musculoskeletal pain, arthralgia etc. affected physical domains (physical function, body pain and role physical) and physical component score (PCS) (KW p <0.01 to <0.0001). By linear regression, MELD had a direct and significant association with overall PCS and mental component score (MCS).

Combination of TACE and Sorafenib Improves Outcomes in BCLC Stages B/C of Hepatocellular Carcinoma: A Single Centre Experience

BACKGROUND AND AIM

Transarterial chemoembolization (TACE) or sorafenib is recommended for hepatocellular carcinoma BCLC stages B and C respectively. We studied the role of combination of TACE and sorafenib in BCLC stages B/C.

MATERIAL AND METHODS

We undertook an observational study on a cohort of cirrhotics with HCC from August 2010 through October 2014. Patients in BCLC stages B/C who had received TACE and/or sorafenib were included. mRECIST criteria were used to assess tumor response. The primary end point was overall survival.

RESULTS

Out of 124 patients, 47.6% were in BCLC-B and 52.4% in BCLCC. Baseline characteristics were comparable. The predominant etiology was cryptogenic (37.2% and 38.5%, p = NS). 49.1% in BCLC-B and 56.9% in BCLC-C had received TACE+sorafenib. In BCLC-B, the overall survival improved from 9 months (95% CI 6.3-11.7) using TACE only to 16 months (95% CI 12.9-19.1) using TACE+sorafenib (p &lt; 0.05). In BCLC-C, addition of TACE to sorafenib improved the overall survival from 4 months (95%CI 3-5) to 9 months (95%CI 6.8-11.2) (p &lt; 0.0001). As per mRECIST criteria, patients on TACE+sorafenib had reduced progressive disease (37.8% vs. 83.3%), improved partial response (43.2% vs. 3.3%) and one had complete response compared to those on sorafenib alone (p &lt; 0.0001) in BCLC-C but not in BCLC-B group. Hand foot syndrome was noted in 27.7% patients on sorafenib and post TACE syndrome in 80.2% patients, but both were reversible. No major adverse events were noted.

CONCLUSION

TACE+sorafenib was more effective than TACE or sorafenib alone in HCC BCLC stages B or C with a significant survival benefit and improved tumour regression especially in BCLC-C patients.

Role of Colonoscopy in Differentiating Intestinal Tuberculosis from Crohn’s Disease

Background: The interface between tuberculosis (TB) and Crohn’s disease (CD) is relevant as TB complicates both the diagnosis and management of CD. Aim: This study aimed to identify the distinctive characteristics of ileocaecal and colonic TB (C‑TB) and colonic CD (C‑CD) at colonoscopy and to correlate the colonoscopy findings with histology. Materials and Methods: This prospective study included consecutive patients presenting with classical symptoms of TB or CD. The colonoscopic findings were compared with histology, which was taken as gold standard. Appropriate statistical tests were applied. Results: Fifty‑eight individuals fulfilled the inclusion criteria. Nine and 16 patients with C‑TB and C‑CD, respectively, had histological confirmation of respective diagnosis. In 33 specimens, the histological diagnosis was inconclusive. The sensitivity of colonoscopy for diagnosing C‑TB was high at 88.9% (95% confidence interval [CI]: 51.8–99.7). It was 50% (95% CI: 24.7–75.4) for CD. The reverse was true for CD whose specificity was high at 71.4% (95% CI: 55.3–84.3) and low for TB at 46.9% (95% CI: 32.5–61.7). All the patients diagnosed as confirmed CD or TB responded well to respective treatment. Six of the thirty patients with failed response to anti‑TB treatment required surgery or change in treatment after 2 months. Conclusion: Colonoscopic findings of isolated ileal involvement, aphthous ulcer, cobble stoning, long‑segment strictures, skip lesions and perianal involvement favored a diagnosis of CD. Correlation of colonoscopy with histology is poor for both CD and TB. The accuracy, sensitivity and specificity of colonoscopy were better and superior for the diagnosis of CD, than in the diagnosis of TB.

Malignant Hepatic Epithelioid Hemangioendothelioma with Villaret Syndrome

Malignant hepatic epithelioid hemangioendothelioma is a rare, vascular tumor of the liver with peak incidence in the middle age with a female preponderance and of unknown etiology. Majority of the tumors are asymptomatic. The gold standard for diagnosis of the tumor is liver histology showing presence of epithelioid tumor cells on a background of a hyaline stroma. Immunohistochemical positivity for CD31, CD34, Factor VIII, and Podoplanin (D2-40) is confirmatory. The treatment of choice is liver transplantation.

Chronic hepatitis C virus infection in India: Regional demographics and distribution of viral genotypes

BACKGROUND AND AIMS

Although chronic hepatitis C virus (HCV) infection affects millions of people in India, few studies have assessed host, viral, and disease characteristics of chronically infected patients at national and regional levels. Such information is critical to support large scale screening and treatment initiatives for chronic HCV infection in India.

METHODS

Patients with known chronic HCV infection making routine or for-cause visits to the participating study centers were enrolled in this observational study. Patients attended a single outpatient visit during which demographics and medical history were collected, a physical examination was performed, and blood and urine samples were collected for laboratory assessments. Samples were analyzed to determine HCV genotypes and subtypes, and genotypes of interferon lambda 3 (IFNL3) single nucleotide polymorphism. No therapeutic interventions were administered.

RESULTS

We enrolled 500 patients at 19 centers, categorized into four geographic regions (North, South, East, and West). All patients self-identified as Indian, and most (66 %) were male. Genotype 3 was the most common genotype overall (54 %); however, its prevalence varied greatly by region, ranging from 34 % in the South to 69 % in the East. Genotypes 1 (24 %) and 4 (6 %) were the next most common, and HCV genotype could not be determined for 16 % of patients.

CONCLUSIONS

This prospective survey suggests that demographics, viral, and host factors in patients with chronic HCV infection are highly variable in India and pose significant challenges for the implementation of broad-scale screening and treatment initiatives.

Composition of gallbladder bile in healthy individuals and patients with gallstone disease from north and South India

BACKGROUND

Gallstones (GS) in south India (SI) are predominantly pure pigment or mixed, while in North India (NI), these are either pure cholesterol or mixed. While cholesterol rich gallbladder (GB) bile predicts cholesterol GS, constituent of bile in primary pigment GS is not known. We compared the composition of GB bile from healthy liver donors and patients with GS from north and south India.

METHODS

Gallbladder bile from healthy liver donors from north (10) and south India (8) served as controls. Cases were patients from north (21) and south India (17) who underwent cholecystectomy for GS disease. Gallbladder bile from both cases and controls was analyzed for cholesterol, lecithin (phospholipid), and bile salts. Gallstones were classified as cholesterol, mixed, and pigment based on morphology and biochemical analysis.

RESULTS

The median cholesterol concentration in control bile from north was significantly high compared to south (p<0.001) with no difference in lecithin and bile salts (p NS). Except for one sample each from north and south, the cholesterol solubility of controls was within the critical micellar zone. Mixed GS were most frequent in north India (61.9 %) while pigment GS dominated in south (61.9 %). The median cholesterol concentration in bile samples of cholecystectomy patients from north India was significantly high GS (p < 0.00001) with significant lowering of bile salts and lecithin (p < 0.00001). In south India, patients with mixed GS had high cholesterol content in bile compared to controls and patients with pigment GS; bile in latter had significantly higher concentration of bile salt compared to controls and mixed GS. The ternary plot confirmed the composition of GB bile from north and south India.

CONCLUSIONS

Gallbladder bile in controls and patients with GS from north India had significantly high cholesterol concentration. In south India, patients with mixed GS had cholesterol rich bile while pigment GS had higher concentrations of bile salts.

Anaesthesia and intensive care for simultaneous liver-kidney transplantation: A single-centre experience with 12 recipients

Background and Aims:

The perioperative management of patients presenting for simultaneous liver and kidney transplantation (SLKT) is a complex process. We analysed SLKTs performed in our institution to identify preoperative, intraoperative and post-operative challenges encountered in the management.

Methods:

We retrospectively studied the case records of 12 patients who underwent SLKT between 2009 and 2014 and analysed details of pre-operative evaluation and optimisation, intraoperative anaesthetic management and the implications of use of perioperative continuous renal replacement therapy (CRRT) and the post-operative course of these patients.

Results:

Of the total 12 cases, 4 were under 16 years of age. The indications for SLKT were primary hyperoxaluria (5), congenital hepatic fibrosis with polycystic kidney disease (2), ethanol-related end-stage liver disease (ESLD) with hepatorenal syndrome type 1 (1). Four patients had ESLD with end-stage renal disease due to other causes. Six recipients received live donor grafts and 6 patients received cadaveric grafts. Seven patients received intraoperative CRRT. Mean duration of surgery was 12.5 h. Cardiac output monitors used were trans-oesophageal echocardiogram (2), pulmonary artery catheter (1) and pulse contour cardiac output monitor (3). There was 1 sepsis-related mortality on 7^th post-operative day.

Conclusion:

A thorough pre-operative evaluation and optimisation, knowledge and anticipation of potential problems, and meticulous intraoperative fluid management guided by appropriate monitoring and use of CRRT when needed can help in achieving successful outcomes.

Safe emergency evacuation of a Tertiary Care Hospital during the "once in a century" floods in Chennai, India

The coastal city of Chennai, India, was inundated by unprecedented heavy rains during the last week of November 2015, in what was billed as a "once in a century" floods. Over 350 people lost their lives in the floods. Global Hospital, a 250-bedded tertiary care hospital in Chennai, was heavily flooded leaving more than 100 patients and their relatives stranded inside with access totally cutoff from the rest of the world. This article describes how these patients, many in the Intensive Care Unit on ventilators, were safely managed within the hospital for over 48 h on very limited power supply and resources and then safely evacuated by fishing boats to three other city hospitals. Careful planning, anticipating hazards, identifying critical areas, effective communication and team work contributed to the successful management of this situation.

POEMS syndrome associated with plasmacytoma of the clivus: "Time discovers the truth"

Polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes (POEMS) syndrome is characterized by the presence of a monoclonal plasma cell disorder, peripheral neuropathy, and one or more of the following features: Osteosclerotic myeloma, Castleman's disease (angiofollicular lymph node hyperplasia), increased levels of serum vascular endothelial growth factor (VEGF), organomegaly, endocrinopathy, edema, typical skin changes, and papilledema. [1] Solitary plasmacytomas most frequently occur in the bone but can also be found in soft tissues (extramedullary plasmacytoma). [2] We report a case that showed a rare association of POEMS syndrome with a plasmacytoma of the clivus.
