Outcomes of jaundice in advanced hepatocellular carcinoma - a sub-Saharan perspective.

BACKGROUND: Jaundice is a marker of advanced disease and poor outcomes in hepatocellular carcinoma (HCC). The aim of this study was to describe and analyse the management and outcomes of jaundiced HCC patients at a large academic referral centre in sub-Saharan Africa (SSA). METHODS: Treatment-naïve adult HCC patients who presented with jaundice between 1990 and 2023 were analysed. RESULTS: During the inclusion period, 676 HCC patients were treated at Groote Schuur Hospital. The mean age of the 126 (18.6%) who were jaundiced was 48.8 (± 13.2) years. Eighty-nine (70.6%) were male. Ninety-four (74.6%) patients with jaundice secondary to diffuse tumour infiltration had best supportive care (BSC) only. Thirty-two had obstructive jaundice (OJ); four were excluded because of missing hospital records. In 28 of these patients, 16 underwent biliary drainage (BD) and 12 received BSC only. The mean overall survival (OS) of the 126 patients was 100.5 (± 242.3) days. The patients with diffuse tumour infiltration had an OS of 105.9 (± 273.3) days. The patients with OJ survived 86.5 (± 135.0) days. There was no significant difference in OS between the three patient groups (p = 0.941). In the OJ group, patients who underwent BD survived longer than the BSC group (117.9 ± 166.4 vs. 29.2 ± 34.7 days, p = 0.015).

Prognostic markers in hepatitis A-related pediatric acute liver failure and validation of the Peds-hepatitis A virus prognostic model.

OBJECTIVES: Hepatitis A virus (HAV) is the commonest cause for pediatric acute liver failure (PALF) in India. The objective of the study was to identify the predictors of mortality and to evaluate the utility of Peds-HAV model in a cohort of non-LT HAV-PALF. METHODS: The study included HAV-related PALF from two non-transplant centers. The predictors of outcome were identified by univariate analysis followed by Cox regression analysis. The prognostic accuracy of Peds-HAV model, King's College Hospital (KCH) criteria and pediatric end-stage liver disease score (PELD) were evaluated. RESULTS: As many as 140 children with PALF were included, of whom 96 (68.6%) children had HAV-PALF. On Cox regression analysis, international normalized ratio (INR) (p < 0.001), jaundice to encephalopathy (JE) interval (p < 0.001) and hepatic encephalopathy (HE) grade 3/4 (p = 0.01) were independent predictors of mortality. The mortality rates were 0% (0/42), 14.3% (3/21), 60% (9/15) and 94.4% (17/18) when none, 1, 2 or 3 criteria of the Peds-HAV were met, respectively. Peds-HAV model at a listing cut-off of  ≥ 2 criteria predicted death with 89.7% sensitivity and 89.6% specificity. In contrast, KCH criteria had a lower sensitivity of 62.1%. PELD score had a sensitivity of 89.7% and specificity of 85.1% at a cut-off of 30. The overall prognostic accuracy of Peds-HAV model (89.6%) was higher than those of KCH (83.3%) and PELD (86.5%). CONCLUSION: INR, HE grade and JE interval were independent predictors of mortality. The study provides an external validation of Peds-HAV model as a prognostic score in HAV-PALF. CLINICAL TRIAL REGISTRY NUMBER: Not applicable as this is a retrospective study.

A comparative study of uncomplicated acute non-A-E hepatitis with acute viral hepatitis and acute onset autoimmune hepatitis.

BACKGROUND AND AIMS: Non-A-E hepatitis (NAEH) not leading to acute liver failure (ALF) is poorly documented. The objective was to compare clinical and laboratory features of uncomplicated acute NAEH with acute viral (AVH) and autoimmune hepatitis (AIH) and histopathology in NAEH and AIH. METHODS: Cases of hepatocellular jaundice were included. These were grouped into AVH, AIH and NAEH based on clinical, laboratory and, when indicated, liver biopsy findings. NAEH and AIH were followed up at three months. RESULTS: Of 336 patients with hepatocellular jaundice, 15 (5%) were NAEH, 25 (7%) acute AIH and 45 (14%) AVH. Among NAEH patients, seven (46.7%) were males with a mean age of presentation 39 years. Jaundice (100%) was the most common presentation of NAEH. Peak bilirubin was 10.7 mg/dL. Peak aspartate and alanine aminotransferase (AST, ALT) were 512 and 670 U/L. Five (33.3%) patients had positive anti-nuclear antibody and one had anti-smooth muscle antibody. Mean immunoglobulin G (IgG) levels were 1829. On liver biopsy, all had ballooning degeneration, four (26.7%) had mild and three (20%) moderate interface hepatitis, four (26.7%) mild lymphoplasmacytic infiltrate, one (6.7%) rosette formation, bridging necrosis in none and stage 1 fibrosis in one. Comparing NAEH with AIH, AIH showed significantly older age at presentation, female predisposition, past history of jaundice, lower ALT, more autoantibodies, higher IgG, higher grade interface hepatitis, lymphoplasmacytic infiltrate, rosette formation and higher bilirubin, AST at three months. NAEH and viral hepatitis had similar features. CONCLUSION: Etiology of NAEH is unlikely to be autoimmune and is probably viral, unidentified as yet. Uncomplicated NAEH likely has self-limiting course even without specific treatment.

Jaundice caused by primary common bile duct lymphoma of a cat.

A 10-year-old American Shorthair cat presented with anorexia and jaundice, and echogenic evaluation revealed diffuse thickening of the common bile duct (CBD) wall. An exploratory laparotomy was conducted, the lesion was evaluated as difficult to remove, and the cat was euthanized and autopsied. Histologically, round neoplastic cells proliferated in the mucosa of the CBD and infiltrated the hepatic lobe, pancreas, and duodenum. Immunohistochemistry revealed that the neoplastic cells were positive for cytoplasmic-CD3 and granzyme B, and TCR-gamma clonal rearrangement was detected. Based on these findings, the neoplasia was diagnosed as a primary CBD lymphoma originating from cytotoxic T or natural killer cells. To the best of our knowledge, this is the first reported case of feline primary CBD lymphoma. Although rare, lymphoma of the CBD should be considered in cats with jaundice and thickening of the CBD.

Acute grade IV toxic hepatitis due to the e-cigarette.

A 46-year-old woman presented at the emergency department because of acute hepatitis with jaundice. After hepatological work-up including liver biopsy, drug induced liver disease (DILI) was suspected. Patient recovered completely within a few months. One year later she presented again with jaundice due to acute hepatitis. Vaping was the only agent that could be identified as causative agent for DILI. After VAPING cessation, the hepatitis resolved completely. Calculated RUCAM score was 10, making the diagnosis of toxic hepatitis very likely. During follow-up liver tests remained normal. This is the first report of severe DILI secondary to the use of e-cigarettes. In future vaping can be included in the differential diagnosis of DILI.

Hepatitis E virus infections among patients with acute febrile jaundice in two regions of Cameroon: First molecular characterization of hepatitis E virus genotype 4.

BACKGROUND: Febrile jaundice is a common indicator of certain infectious diseases, including hepatitis E. In Cameroon, the yellow fever virus is the only pathogen that is monitored in patients who present with this symptom. However, more than 90% of the samples received as part of this surveillance are negative for yellow fever. This study aimed to describe the prevalence and hepatitis E virus (HEV) genotype among yellow fever-negative patients in the Far North and West regions of Cameroon. METHODS: In a cross-sectional study, yellow fever surveillance-negative samples collected between January 2021 and January 2023 were retrospectively analyzed. Anti-HEV IgM and IgG antibodies were tested using commercially available ELISA kits. Anti-HEV IgM and/or IgG positive samples were tested for HEV RNA by real-time RT-PCR, followed by nested RT-PCR, sequencing and phylogenetic analysis. RESULTS: Overall, 121 of the 543 samples (22.3%, 95% CI: 19.0% - 26.0%) were positive for at least one anti-HEV marker. Amongst these, 8.1% (44/543) were positive for anti-HEV IgM, 5.9% (32/543) for anti-HEV IgG, and 8.3% (45/544) for both markers. A total of 15.2% (12/79) samples were positive for HEV RNA real-time RT-PCR and 8 samples were positive for HEV RNA by nested RT-PCR. Phylogenetic analysis showed that the retrieved sequences clustered within HEV genotypes/subtypes 1/1e, 3/3f and 4/4b. CONCLUSION: Our results showed that HEV is one of the causes of acute febrile jaundice in patients enrolled in the yellow fever surveillance program in two regions of Cameroon. We described the circulation of three HEV genotypes, including two zoonotic genotypes. Further studies will be important to elucidate the transmission routes of these zoonotic HEV genotypes to humans in Cameroon.

Jaundice in a Child with Sickle Cell Anemia: A Case Based Approach.

Sickle cell anemia (SCA) is an autosomal recessive disorder caused by a mutation in beta globin gene. Hepatobiliary system is affected in 10-40% of patients with SCA and has a multifactorial etiology. The authors present a child with SCA and conjugated hyperbilirubinemia due to biliary obstruction. He underwent endoscopic retrograde cholangiopancreatography (ERCP) and biliary stenting, had complications of post sphincterotomy bleed, retroperitoneal hematoma and post laparoscopic cholecystectomy sepsis with acute sickle hepatic crisis. He was managed successfully and is doing well on follow-up. Here authors discuss a stepwise approach in management of jaundice in a patient with SCA. Patients with SCA are prone to develop vaso-occlusive crisis (VOC) during periods of stress. VOC affects the liver as acute sickle hepatic crisis, acute hepatic sequestration or sickle cell intrahepatic cholestasis and is collectively termed as sickle cell hepatopathy. Hemolysis due to sickling results in cholelithiasis with its associated complications. These patients are vulnerable to viral hepatitis and hemochromatosis due to multiple blood transfusions. There may be a concomitant acute viral hepatitis, drug induced liver injury, Budd-Chiari syndrome or other chronic liver diseases. These conditions have considerable clinical overlap and may coexist, making the evaluation more challenging. Detailed history, examination and investigations are required for differentiation of etiology. Periods of stress must be tackled with proper hydration, oxygen supplementation, maintaining hemoglobin >10 g/dL, and a low hemoglobin S fraction. Patients with SCA and conjugated hyperbilirubinemia are "high-risk" and best managed by a multidisciplinary team. Preventive strategies like timely vaccinations, chelation, etc. must be practised.

Skin branding for jaundice in children: A brutal cultural dermatosis.

Dermatological conditions associated with socio-cultural and religious practices, known as "cultural dermatoses," are commonly seen in medical practice. This article presents seven cases of children who underwent skin branding for jaundice in Southern India. Skin branding, a traditional healing method, involves applying heated objects to cause third-degree burns. Healthcare providers should be aware of these cultural practices to avoid misdiagnosis.

Successful Treatment with Steroids in a Patient with Vanishing Bile Duct Syndrome and Acute Tubular Necrosis.

Vanishing bile duct syndrome (VBDS) is a rare but potentially serious cholestatic liver disease caused by various etiologies, including drugs. We herein report a complicated case of VBDS with acute tubular necrosis (ATN) that improved significantly with steroid treatment. An Asian man in his 30s was admitted with the acute onset of severe jaundice and a decline in the renal function. Although initial treatment with ursodeoxycholic acid did not reduce jaundice or renal dysfunction, steroid treatment remarkably improved the VBDS and ATN to within the respective normal ranges. Steroid treatment can be considered in cases of VBDS that appear to have an immune-mediated cause.

The association between jaundice and poorly differentiated pancreatic neuroendocrine neoplasms (Ki67 index > 55.0%).

BACKGROUND: Jaundice occurs in some pancreatic disease. However, its occurrences and role in pancreatic neuroendocrine neoplasms (PNENs) has not been well studied. In this study we showed the association between jaundice and the risk of high grade and poorly differentiated PNENs. METHODS: Ninety-three patients with head-neck PNENs were included. Poorly differentiated pancreatic neuroendocrine neoplasms were defined by a ki67 index > 55.0%. Logistic regression was used to show the association between demographic information, clinical signs and symptoms and the risk of poorly differentiated tumors. A nomogram model was developed to predict poorly differentiated tumor. RESULTS: Eight of 93 PNEN patients (8.6%) had jaundice. The age and ki67 index in patients with jaundice were significantly higher than those patients without jaundice. All jaundice occurred in patients with grade 3 PNENs. Mutivariable regression analysis showed that age (odds ratio(OR) = 1.10, 95% confidence interval (CI):1.02-1.19), tumor size (OR = 1.42, 95%CI:1.01-2.00) and jaundice (OR = 14.98, 95%CI: 1.22-184.09) were associated with the risk of poorly differentiated PNENs. The age and size combination showed a good performance in predicting poorly differentiated PNENs (area under the curve (AUC) = 0.81, 95% CI: 0.71-0.90). The addition of jaundice further improved the age- and size-based model (AUC = 0.86, 95% CI: 0.78-0.91). A nomogram was developed based on age, tumor size and jaundice. CONCLUSION: Our data showed that jaundice was associated with the risk of high grade PNENs and poorly differentiated PNENs.

Risk factors for postoperative pancreatic fistula following non-traumatic, pancreatic surgery. Retrospective observational study.

Pancreatic surgery e pancreatic fistula (POPF) is a potentially fatal sequela with substantial morbidity and mortality. POPF incidence and risk factors vary. This study aimed to evaluate the incidence and risk factors of patients with pancreatic fistula (PF) from patients undergoing various pancreatic surgeries for different pancreatic diseases. MATERIAL AND METHODS: A retrospective observational study was conducted in the surgical unit of our university hospitals from July 2014 to July 2019. Three hundred forty-seven patients were admitted with a clinical diagnosis of pancreatic fistula following both open and laparoscopic approaches for pancreatic benign and malignant tumors. RESULTS: The most prevalent age was >60 years (67%), with a male predominance (83%). The most common diagnosis before surgery was pancreatic head adenocarcinoma (32%), followed by duodenal neoplasm (19%) and true epithelial pancreatic cystic neoplasms (18%), ampullary neoplasms (15%), bile duct neoplasms (12%), neuroendocrine neoplasms (2%), and chronic pancreatitis (2%). The most prevalent site of the pancreatic tumor was the head (87%), while accompanied Jaundice (47%) and epigastric discomfort (37%) were the commonest presentations before surgery. Pancreatic duct diameter greater than 3 mm was present in 208 patients (60%), tumor size greater than 3 cm in 63%, hard pancreatic texture in 67%, and preoperative ERCP with a stent in 37% of cases. Tumor in the tail of the pancreas was found in 5% (17 patients) of cases. The commonest operations performed were open pylorus-preserving pancreaticoduodenectomy, open pancreaticoduodenectomy without pylorus-preserving, and open distal pancreatectomy with splenic preservation. Postoperative pancreatic fistula occurred in 8% of cases (27), with ISPGF grade A (biochemical leak) occurring in 17 patients (17/27) and clinically significant POPF occurring in 10 patients (10/27). POPF occurred in 13 patients after distal pancreatectomy, 11 patients after pancreaticoduodenectomy, two cases followed central pancreatectomy, and one. Grade B after pancreaticoduodenectomy and two after distal pancreatectomy. Grade C POPF occurred in four patients after pancreaticoduodenectomy but not after distal pancreatectomy. Age >55 (p=0.00), male (p=0.03), presence of symptom (p=0.0008), location at Head of the pancreas (p=0.0004), elevated CA19-9 (p=0.0004), jaundice (p=0.0001) and pancreatic texture (p=0.00**). CONCLUSION: Pancreatic fistula occurred in 27 patients (8%), a comparatively low incidence. POPF was linked to age, Jaundice, gender, pancreatic head cancer, symptoms, high CA 19-9, jaundice, and a soft pancreas. POPF incidence was higher after distal pancreatectomy, whereas POPF severity was higher after pancreaticoduodenectomy KEY WORDS: Pancreaticoduodenectomy, Pancreatic Fistula, Pancreatic Resection, Postoperative Complications.
