Immune checkpoint inhibitor use and the incidence of hepatitis B virus reactivation or immune-related hepatitis in non-small cell lung cancer patients with chronic hepatitis B.

BACKGROUND: The safety of immune-checkpoint inhibitors (ICIs) has not been thoroughly investigated in non-small cell lung cancer (NSCLC) patients with chronic hepatitis B (CHB) or occult hepatitis B infection (OBI). The authors analyzed the incidence of hepatitis B virus (HBV) reactivation, immune-related hepatitis and jaundice in NSCLC patients in a real-world setting. METHODS: A total of 1277 NSCLC patients treated with ICIs were analyzed. Among them, 52 patients were hepatitis B surface antigen (HBsAg) (+) (group A, CHB), 759 patients were HBsAg (-)/hepatitis B core antibody immunoglobulin G (anti-HBc IgG) (+) (group B, OBI), and 466 patients were HBsAg (-)/anti-HBc IgG (-) (group C). Among the 52 patients with CHB, 38 (73.1%) were receiving antiviral therapy. The primary end point was HBV reactivation, immune-related hepatitis, and jaundice. The secondary end points included other immune-related adverse events and efficacy. RESULTS: HBV reactivation was observed in two patients (0.2%) who were both in group A (CHB). Among CHB patients who were not receiving antiviral therapy, HBV reactivation was observed in 14.3% (2 of 14 patients). The incidences of immune-related hepatitis and jaundice were comparable among the three groups. The incidence of ≥grade 3 other immune-related adverse events and efficacy were all comparable among the three groups (p > .05 for all comparisons). CONCLUSIONS: In this large, real-world cohort study, the safety and efficacy of ICIs were comparable in patients with CHB and OBI. HBV reactivation was observed in patients with CHB without antiviral therapy indicating antiviral prophylaxis should be required for them. For patients with OBI, the risk of HBV reactivation was minimal.

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.

Endoscopic ultrasound-guided gallbladder drainage as a first approach for jaundice palliation in unresectable malignant distal biliary obstruction: Prospective study.

OBJECTIVES: Endoscopic retrograde cholangiopancreatography (ERCP) represents the gold standard for jaundice palliation in patients with distal malignant biliary obstruction (DMBO). Biliary drainage using electrocautery lumen apposing metal stent (EC-LAMS) is currently a well-established procedure when ERCP fails. In a palliative setting the endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) could represent an easy and valid option. We performed a prospective study with a new EC-LAMS with the primary aim to assess the clinical success rate of EUS-GBD as a first-line approach to the palliation of DMBO. METHODS: In all, 37 consecutive patients undergoing EUS-GBD with a new EC-LAMS were prospectively enrolled. Clinical success was defined as bilirubin level decrease >15% within 24 h and >50% within 14 days after EC-LAMS placement. RESULTS: The mean age was 73.5 ± 10.8 years; there were 17 male patients (45.9%). EC-LAMS placement was technically feasible in all patients (100%) and the clinical success rate was 100%. Four patients (10.8%) experienced adverse events, one bleeding, one food impaction, and two cystic duct obstructions because of disease progression. No stent-related deaths were observed. The mean hospitalization was 7.7 ± 3.4 days. Median overall survival was 4 months (95% confidence interval 1-8). CONCLUSION: Endoscopic ultrasound-guided gallbladder drainage with the new EC-LAMS is a valid option in palliative endoscopic biliary drainage as a first-step approach in low survival patients with malignant jaundice unfit for surgery. A smaller diameter EC-LAMS should be preferred, particularly if the drainage is performed through the stomach, to avoid potential food impaction, which could result in stent dysfunction.

Unusual clinical spectra of childhood severe malaria during malaria epidemic in eastern Uganda: a prospective study.

BACKGROUND: In sub-Saharan Africa (SSA), malaria remains a public health problem despite recent reports of declining incidence. Severe malaria is a multiorgan disease with wide-ranging clinical spectra and outcomes that have been reported to vary by age, geographical location, transmission intensity over time. There are reports of recent malaria epidemics or resurgences, but few data, if any, focus on the clinical spectrum of severe malaria during epidemics. This describes the clinical spectrum and outcomes of childhood severe malaria during the disease epidemic in Eastern Uganda. METHODS: This prospective cohort study from October 1, 2021, to September 7, 2022, was nested within the 'Malaria Epidemiological, Pathophysiological and Intervention studies in Highly Endemic Eastern Uganda' (TMA2016SF-1514-MEPIE Study) at Mbale Regional Referral Hospital, Uganda. Children aged 60 days to 12 years who at admission tested positive for malaria and fulfilled the clinical WHO criteria for surveillance of severe malaria were enrolled on the study. Follow-up was performed until day 28. Data were collected using a customized proforma on social demographic characteristics, clinical presentation, treatment, and outcomes. Laboratory analyses included complete blood counts, malaria RDT (SD BIOLINE Malaria Ag P.f/Pan, Ref. 05FK60-40-1) and blood slide, lactate, glucose, blood gases and electrolytes. In addition, urinalysis using dipsticks (Multistix® 10 SG, SIEMENS, Ref.2300) at the bedside was done. Data were analysed using STATA V15.0. The study had prior ethical approval. RESULTS: A total of 300 participants were recruited. The median age was 4.6 years, mean of 57.2 months and IQR of 44.5 months. Many children, 164/300 (54.7%) were under 5 years, and 171/300 (57.0%) were males. The common clinical features were prostration 236/300 (78.7%), jaundice in 205/300 (68.3%), severe malarial anaemia in 158/300 (52.7%), black water fever 158/300 (52.7%) and multiple convulsions 51/300 (17.0%), impaired consciousness 50/300(16.0%), acidosis 41/300(13.7%), respiratory distress 26/300(6.7%) and coma in 18/300(6.0%). Prolonged hospitalization was found in 56/251 (22.3%) and was associated with acidosis, P = 0.041. The overall mortality was 19/300 (6.3%). Day 28 follow-up was achieved in 247/300 (82.3%). CONCLUSION: During the malaria epidemic in Eastern Uganda, severe malaria affected much older children and the spectrum had more of prostration, jaundice severe malarial anaemia, black water fever and multiple convulsions with less of earlier reported respiratory distress and cerebral malaria.

A novel smartphone scleral-image based tool for assessing jaundice in decompensated cirrhosis patients.

BACKGROUND AND AIM: Serum bilirubin is an established marker of liver disease. Reliable tools for non-invasive assessment of jaundice in cirrhosis patients, at risk of clinical decompensation, are highly desirable. While smartphone-based imaging has been described in neonatal jaundice, it has not been investigated in advanced cirrhosis patients. METHODS: We included 46 hospitalized patients with acute cirrhosis decompensation and jaundice. Scleral images using an Android smartphone were taken to derive "Scleral Color Values (SCV)," which were matched with same day serum bilirubin measurements. In 29 patients, repeat SCV and bilirubin measurements were performed over time. We analyzed the relationship of SCV and its dynamics with serum bilirubin, clinical scores, and patient outcomes. RESULTS: Of 46 patients, 26 (57%) had alcoholic hepatitis as the decompensation precipitant. Seven patients died during admission; a further 12 following hospital discharge. SCV had an excellent linear correlation with serum bilirubin (rho = 0.90, P < 0.001); changes in SCV and serum bilirubin across different time points, were also closely associated (rho = 0.77, P < 0.001). SCV correlated significantly with CLIF Consortium Acute Decompensation score (rho = 0.38, P < 0.001) and grade of Acute-on-Chronic Liver Failure (rho = 0.42, P = 0.039). SCV was higher in patients who died, however, not significantly (86.1 [IQR 83.0-89.7] vs 82.3 [IQR 78.5-83.3], P = 0.22). The associations of SCV with clinical parameters mirrored those of serum bilirubin. CONCLUSION: Smartphone-based assessment of jaundice shows excellent concordance with serum bilirubin and is associated with clinical parameters in acute cirrhosis decompensation. This approach offers promise for remote assessment of cirrhosis patients at-risk of decompensation, post hospital discharge.

Comparison of severity and prognosis of jaundice due to Rh incompatibility and G6PD deficiency.

INTRODUCTION: Undiagnosed and untreated hyperbilirubinemia in infants may result in Kernicterus Spectrum Disorder and poor prognoses. Rhesus incompatibility and glucose-6-phosphate dehydrogenase (G6PD) deficiency are among the known causes of infantile jaundice. This study was designed to define the severity and prognosis in jaundiced infants with Rh incompatibility or G6PD deficiency. METHODS: A total of 144 term, 2- 14 days old jaundiced infants (bilirubin > 20 mg/dl) with Rh incompatibility(85 infant) or G6PD deficiency(59 infant) were included in this cohort study with 24-month follow-up through available sampling at Ghaem hospital between 2015 and 2022. Denver II test was used at 6, 12, 18, and 24-month ages after discharge. Infants with Rh incompatibility or G6PD deficiency were assigned into two groups of favorable and poor prognosis. Following that, the bilirubin levels of these infants were compared at the time of admission. RESULTS: The bilirubin level in G6PD deficient infants with poor prognoses (37.96 ± 9.25 mg/dl) and neonates with Rh incompatibility (36.23 ± 5.08 mg/dl) almost was the same (P = 0.232). 40 babies (47%) caused by Rh incompatibility and 33 (56%) babies caused by G6PD deficiency had a poor prognosis (P = 0.465). Average bilirubin in babies with RH incompatibility with favorable prognosis is 21.8 and poor prognosis is 36.2 mg/dl. In infants with G6PD deficiency, it was 24 mg/dl with favorable prognosis and 38 mg/dl with poor prognosis (P < 0.0001). The severity of hyperbilirubinemia had a significant role in the prognosis of infants in both groups (P < 0.0001). CONCLUSION: The two-year prognoses of hyperbilirubinemia caused by G6PD deficiency are as poor as that of Rh incompatibility. The severity of hyperbilirubinemia had a significant role in the prognosis of infants in both groups.Exchange transfusion in cases with bilirubin < 25 mg/dl can improve the prognosis in both groups, especially in infants with Rh incompatibility.

Associations between neonatal jaundice and autism spectrum disorder or attention deficit hyperactivity disorder: Nationwide population based cohort study.

BACKGROUND/PURPOSE: Neonatal jaundice might result brain insults. Both autistic spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) are developmental disorders, which might result from early brain injury at neonatal period. We aimed to explore the association between neonatal jaundice treated with phototherapy and the ASD or ADHD. METHODS: This retrospective nationwide population cohort study was based on a nationally representative database of Taiwan, and neonates born from 2004 to 2010 were enrolled. All eligible infants were divided into 4 groups, without jaundice, jaundice with no treatment, jaundice with simple phototherapy only and jaundice with intensive phototherapy or blood exchange transfusion (BET). Each infant was follow-up until the date of incident primary outcomes, death, or 7-year-old, whichever occurred first. Primary outcomes were ASD, ADHD. Using cox proportional hazard model to analyze their associations. RESULTS: In total, 118,222 infants with neonatal jaundice were enrolled, including diagnosed only (7260), simple phototherapy (82,990), intensive phototherapy or BET (27,972 infants). The cumulative incidences of ASD in each group was 0.57%, 0.81%, 0.77%, and 0.83%, respectively. The cumulative incidences of ADHD in each group was 2.83%, 4.04%, 3.52% and 3.48%, respectively. Jaundice groups were significantly associated with ASD, ADHD, or either one, even after all other extraneous maternal and neonatal variables were adjusted. After stratification, the associations were still existed in subgroup with birth weights ≥2500 grams and in male subgroup. CONCLUSION: Neonatal jaundice correlated with the ASD and ADHD. The associations were significant in infants of both sexes and with birth weights larger than 2500 grams.

Perioperative Broad-spectrum Antibiotics are Associated With Decreased Surgical Site Infections Compared to 1st-3rd Generation Cephalosporins After Open Pancreaticoduodenectomy in Patients With Jaundice or a Biliary Stent.

OBJECTIVE: Compare the effectiveness of 1st-3rd generation cephalosporins (1st-3rdCE) to broad-spectrum antibiotics in decreasing surgical site infections (SSI) after pancreatectomy. SUMMARY OF BACKGROUND DATA: SSI is one of the most common complications after pancreatic surgery. Various antibiotic regimens are utilized nationwide with no clear guidelines for pancreatectomy. As we await results of a recently initiated prospective trial, this study retrospectively evaluates over 15,000 patients using the same administrative data abstraction tools as in the trial. METHODS: All relevant clinical variables were collected from the 2016-2018 targeted-pancreatectomy database from the American College of Surgeon National Surgical Quality Improvement Program. Preoperative antibiotics were initially collected as first-generation cephalosporin, second or third-generation cephalosporin, and broad-spectrum antibiotics (Broad-abx). RESULTS: Of the 15,182 patients who completed a pancreatic surgery between 2016 and 2018, 6114 (40%) received a first-generation cephalosporin, 4097 (27%) received a second or third-generation cephalosporin, and 4971 (33%) received Broad-abx. On multivariate analysis, Broad-abx was associated with a decrease in all-type SSI compared to 1st-3rdCE (odds ratio = 0.73-0.77, P < 0.001) after open pancreaticoduodenectomy (PD). There was no difference in SSI between antibiotic-types after distal pancreatectomy. Subgroup multivariate analysis of open PD revealed decrease in all-type SSI with Broad-abx amongst patients with jaundice and/or biliary stent only, regardless of wound protector use (odds ratio = 0.69-0.70, P < 0.001). Propensity score matching of open PD patients with jaundice and/or biliary stent confirmed a decrease in all-type SSI (19% vs 24%, P = 0.001), and organ-space SSI (12% vs 16%, P < 0.001). CONCLUSION: Broad-abx are associated with decreased SSI after open PD and may be preferred specifically for patients with preoperative biliary stent and/ or jaundice.

Vanishing Bile Duct Syndrome Secondary to Hodgkin Lymphoma in a Child.

Vanishing bile duct syndrome (VBDS) is a condition resulting from progressive destruction and loss of intrahepatic bile ducts leading to cholestasis, biliary cirrhosis, and liver failure. It occurs secondary to various pathologic conditions like autoimmune diseases, graft versus host disease, drug reactions, and as a paraneoplastic syndrome in malignancies. We here described a 9-year-old girl who presented with cervical lymphadenopathy and jaundice. This child was diagnosed as a case of Hodgkin lymphoma. All other causes of cholestasis were ruled out by appropriate investigations (particularly autoimmune, metabolic, infections, and drug-induced possibilities). On liver biopsy, her diagnosis was established as VBDS. In view of hepatic dysfunction, alternative chemotherapy with dexamethasone, high-dose cytarabine, and cisplatin (DHAP) was given, and she was started on hepatoprotective measures with ursodeoxycholic acid. Hepatic function gradually improved after the initiation of chemotherapy. VBDS is considered a dismal paraneoplastic syndrome with a high-case fatality. This case report highlights the importance of early recognition and initiation of appropriate full-dose chemotherapy as the only way to achieve complete resolution of VBDS.

Differential effects of delayed cord clamping on bilirubin levels in normal and diabetic pregnancies.

The purpose of the study is to investigate the effects of delayed cord clamping on bilirubin levels and phototherapy rates in neonates of diabetic mothers. This was a prospective study that enrolled pregnant women without pregnancy complications and those with diabetes. Their neonates were randomized in a 1:1 ratio to delayed cord clamping. The main outcomes were the neonatal transcutaneous bilirubin values on 2-4 days postpartum and the rate of requiring phototherapy in infants. A total of 261 pregnant women were included in the final analysis (132 women with diabetic pregnancies and 129 women with normal pregnancies). In diabetic pregnancies, neonatal bilirubin levels on the 2-4 days postpartum and phototherapy rates were significantly higher in the delayed cord clamping group than in the immediate cord clamping group (7.65 ± 1.83 vs 8.25 ± 1.96, P = 0.039; 10.35 ± 2.23 vs 11.54 ± 2.56, P = 0.002; 11.54 ± 2.94 vs 12.83 ± 3.07 P = 0.024, 18.2% vs 6.3%, P = 0.042), while in normal pregnancies, there was no statistical difference in bilirubin values and phototherapy rates between the delayed cord clamping group and the immediate cord clamping group (P > 0.05). After receiving delayed cord clamping, bilirubin levels on the third postnatal day and the rate of requiring phototherapy in infants were higher in the diabetic pregnancy group than in the normal pregnancy group (10.35 ± 2.23 vs 11.54 ± 2.56, P = 0.013). CONCLUSION: Delayed cord clamping increased the risk of jaundice in newborns born to diabetic mothers, but had no effect in newborns from mothers with normal pregnancies. DCC may be a risk factor for increased bilirubin in infants of diabetic mothers. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04369313; date of registration: April 27, 2020 (retrospectively registered). WHAT IS KNOWN: • Delayed cord clamping had significant benefits for newborns by increasing neonatal hemoglobin levels and reducing the risk of neonatal anemia, etc. • Delayed cord clamping may lead to neonatal hyperemia, erythrocytosis, and hyperbilirubinemia, which increases the risk of neonatal jaundice. WHAT IS NEW: • Our trial focused on the differential effects of delayed cord clamping on jaundice in full-term newborns between diabetic pregnancies and normal pregnancies. And newborns of diabetic mothers who received delayed cord clamping had a significantly increased risk of jaundice compared to newborns with normal pregnancy. • Delayed cord clamping may be a risk factor for increased bilirubin levels in neonates of diabetic mothers.

Prolonged jaundice in hepatitis-E patients: Going beyond the optics.

Hepatitis E virus (HEV) is an RNA virus that is transmitted faeco-orally. Due to unhygienic living conditions and unsatisfactory treatment of drinking water, it is a major cause of acute viral hepatitis in Pakistan. Hepatitis E infection in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency may cause prolonged jaundice resulting in serious complications like, severe haemolysis, acute renal failure, encephalopathy and even demise. Although both these diseases occur frequently in our country there is a dearth of literature on the effect of Hepatitis E infection in G6PD deficient patients, leading to higher rate of complications in such patients. We report the case of a 37 years old male who was referred to our hospital with worsening jaundice. Patient had HEV infection with concomitant G6PD deficiency. This case had a different prospect, since it resulted in prolonged jaundice and severe haemolysis. However the patient's condition improved with conservative management.

Severe acute hepatitis of unknown origin.

At the beginning of 2022, in the United Kingdom, and later in several European countries, a group of pediatric patients who developed acute hepatitis of so far unknown origin was reported. Clinical data include nausea, vomiting, jaundice, and liver failure; some patients require liver transplantation. The affected population is younger than 10 years of age. The probable etiological agent is adenovirus genotype F41, and toxic factors have been ruled out, as well as a relationship with COVID-19. There are several theories to explain this phenomenon, which are being investigated.

A inicios de 2022, en Reino Unido, y posteriormente en varios países europeos, se informó sobre un grupo de pacientes pediátricos que desarrollaron hepatitis aguda de origen desconocido hasta ahora. Los datos clínicos consisten en náusea, vómito, ictericia y falla hepática; algunos pacientes necesitan trasplante hepático. La población afectada es menor a los 10 años. El agente etiológico probable es el adenovirus genotipo F41 y se han descartado factores tóxicos, así como la relación con COVID-19. Existen varias teorías para explicar este fenómeno, las cuales se están investigando.

Dizygotic twins with prolonged jaundice and microcytic, hypochromic, hemolytic anemia with pyropoikilocytosis.

Dizygotic twin males, born at 34 weeks gestation, had prolonged jaundice, microcytic, hypochromic anemia, FABarts hemoglobin, elevated end-tidal CO, and blood films consistent with hereditary pyropoikilocytosis. DNA sequencing revealed both had a heterozygous alpha spectrin (SPTA1) mutation (c.460_462dup) inherited from their asymptomatic mother, plus a 3-base pair duplication in alpha globin (HBA2) (c.364_366dupGTG) inherited from their asymptomatic father.

Maternal Instruction About Jaundice and the Incidence of Acute Bilirubin Encephalopathy in Nigeria.

OBJECTIVE: To evaluate whether teaching mothers about neonatal jaundice will decrease the incidence of acute bilirubin encephalopathy among infants admitted for jaundice. STUDY DESIGN: This was a multicenter, before-after and cross-sectional study. Baseline incidences of encephalopathy were obtained at 4 collaborating medical centers between January 2014 and May 2015 (Phase 1). Structured jaundice instruction was then offered (May to November 2015; Phase 2) in antenatal clinics and postpartum. Descriptive statistics and logistic regression models compared 3 groups: 843 Phase 1 controls, 338 Phase 2 infants whose mothers received both antenatal and postnatal instruction (group A), and 215 Phase 2 infants whose mothers received no instruction (group B) either because the program was not offered to them or by choice. RESULTS: Acute bilirubin encephalopathy occurred in 147 of 843 (17%) Phase 1 and 85 of 659 (13%) Phase 2 admissions, which included 63 of 215 (29%) group B and 5 of 338 (1.5%) group A infants. OR for having acute bilirubin encephalopathy, comparing group A and group B infants adjusted for confounding risk factors, was 0.12 (95% CI 0.03-0.60). Delayed care-seeking (defined as an admission total bilirubin ≥18 mg/dL at age ≥48 hours) was the strongest single predictor of acute bilirubin encephalopathy (OR 11.4; 6.6-19.5). Instruction decreased delay from 49% to 17%. Other major risk factors were home births (OR 2.67; 1.69-4.22) and hemolytic disease (hematocrit ≤35% plus bilirubin ≥20 mg/dL) (OR 3.03; 1.77-5.18). The greater rate of acute bilirubin encephalopathy with home vs hospital birth disappeared if mothers received jaundice instruction. CONCLUSIONS: Providing information about jaundice to mothers was associated with a reduction in the incidence of bilirubin encephalopathy per hospital admission.

Concomitant Existence of Paroxysmal Nocturnal Hemoglobinuria in a Patient with Hb E (HBB: c.79G>A) Trait.

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal disorder that manifests with bone marrow failure, thrombosis and hemolysis. We present a 28-year-old male who presented with weakness, jaundice and transfusion dependence. On initial investigation, he was found to have anemia with jaundice with hemoglobin (Hb) capillary zone electrophoresis suggestive of Hb E (HBB: c.79G>A) trait. The same anomaly was also found in his mother. However, transfusion requirement was an unusual feature in the patient. As his corrected reticulocyte count was raised along with lactate dehydrogenase (LDH), which was suggestive of a hemolytic process, he was worked-up for the same. However, the direct Coombs test was negative. A bone marrow aspiration and biopsy was done to rule out hypersplenism but it revealed erythroid hyperplasia with reduced iron stores despite normal ferritin and iron studies. This was unusual as the patient had anemia requiring transfusions. He had no history of hemoglobinuria but a PNH by flowcytomety revealed a large clone of 81.2% in granulocytes and 88.5% in monocytes. The patient was started on Danazol and steroids for anemia which improved. He was counseled for matched sibling stem cell transplant. He had a full match with his brother. At the time of this study he awaits his transplant.

[Pancreatobiliary Fistula with Jaundice-A Case Report].

An 80-year-old woman was admitted to our hospital due to jaundice. CT and MRCP revealed that the common bile duct and main pancreatic duct were dilatated due to a cystic lesion in the pancreatic head. Moreover, ERCP revealed the presence of a pancreatobiliary fistula and mucus discharge from the enlarged papilla. The patient underwent biliary and pancreatic drainage using plastic stents. However, the treatment was not effective because of the presence of the protein plug. The patient underwent EST because of her rejection to surgery. After the procedure, jaundice was resolved. We report this case with a review of the available literature.

CA 19-9 predicts resectability of pancreatic cancer even in jaundiced patients.

BACKGROUND: Surgical resection remains the only curative option for pancreatic adenocarcinoma. Despite recent improvements in medical imaging, unresectability is still often discovered at the time of surgery. It is essential to identify unresectable patients preoperatively to avoid unnecessary surgery. High serum CA 19-9 levels have been suggested as a marker of unresectability but considered inaccurate in patients with hyperbilirubinemia. AIM OF THE STUDY: To evaluate CA 19-9 serum levels as a predictor of unresectability of pancreatic adenocarcinomas with a special focus on jaundiced patients. METHODS: All patients presenting with histologically-confirmed pancreatic adenocarcinoma and having serum CA 19-9 levels available prior to any treatment were included in this retrospective study. The relationship between serum concentrations of CA 19-9 and resectability was studied by regression analysis and theROC curves obtained. A cut-off value of CA 19-9 was calculated. In jaundiced patients, a CA 19-9 adjusted for bilirubinemia was also evaluated. RESULTS: Of the 171 patients included, 49 (29%) were deemed resectable and 122 (71%) unresectable. Altogether, 93 patients (54%) had jaundice. The area under the ROC curve for CA 19-9 as a predictor of resectability was 0.886 (95%CI:[0.832-0.932]); in jaundiced patients it was 0.880 (95% CI [0.798-0.934]. A cut-off in CA 19-9 at 178 UI/mlyielded 85% sensitivity, 81% specificity and 91% positive predictive value for resectability. There was no correlation between the levels of bilirubin and CA 19-9 (r = 0.149). CONCLUSION: Serum CA 19-9 is a good predictive marker of unresectability of pancreatic adenocarcinoma, even in jaundiced patients. CA 19-9 levels over 178 UI/ml strongly suggest unresectable disease.

MRI-based decision tree model for diagnosis of biliary atresia.

OBJECTIVES: To evaluate MRI findings and to generate a decision tree model for diagnosis of biliary atresia (BA) in infants with jaundice. METHODS: We retrospectively reviewed features of MRI and ultrasonography (US) performed in infants with jaundice between January 2009 and June 2016 under approval of the institutional review board, including the maximum diameter of periportal signal change on MRI (MR triangular cord thickness, MR-TCT) or US (US-TCT), visibility of common bile duct (CBD) and abnormality of gallbladder (GB). Hepatic subcapsular flow was reviewed on Doppler US. We performed conditional inference tree analysis using MRI findings to generate a decision tree model. RESULTS: A total of 208 infants were included, 112 in the BA group and 96 in the non-BA group. Mean age at the time of MRI was 58.7 ± 36.6 days. Visibility of CBD, abnormality of GB and MR-TCT were good discriminators for the diagnosis of BA and the MRI-based decision tree using these findings with MR-TCT cut-off 5.1 mm showed 97.3 % sensitivity, 94.8 % specificity and 96.2 % accuracy. CONCLUSIONS: MRI-based decision tree model reliably differentiates BA in infants with jaundice. MRI can be an objective imaging modality for the diagnosis of BA. KEY POINTS: • MRI-based decision tree model reliably differentiates biliary atresia in neonatal cholestasis. • Common bile duct, gallbladder and periportal signal changes are the discriminators. • MRI has comparable performance to ultrasonography for diagnosis of biliary atresia.

Outcomes of surgical resection of gallbladder cancer in patients presenting with jaundice: A systematic review and meta-analysis.

INTRODUCTION: Preoperative jaundice is considered a relative contraindication to radical gallbladder cancer (GBC) resection due to poor prognosis and high postoperative morbidity. Recent reports have indicated that aggressive surgery may improve long-term survival for patients with advanced GBC who present with obstructive jaundice. The current systematic review and meta-analysis aimed to compare postoperative outcomes among jaundiced and non-jaundiced patients with resectable GBC. METHODS: An electronic search was performed using several Medical Subject Headings terms: cholecyst, gallbladder, tumor, cancer, carcinoma, adenocarcinoma, neoplasia, neoplasm, jaundice, and icterus. Overall survival after surgery was the primary outcome; resectability and postoperative morbidity were the secondary outcomes. RESULTS: Overall survival was shorter among patients who presented with jaundice (Hazard ratio [HR]: 2.21, 95% confidence interval [CI], 1.64-2.97; P < 0.001). Patients with jaundice were less likely to have resectable disease (odds ratio: 0.27, 95% CI, 0.17-0.43; P < 0.001). The jaundice group had higher odds of postoperative morbidity, bile-leak, and posthepatectomy failure versus the non-jaundiced control group. CONCLUSIONS: Radical surgery for GBC resection for patients presenting with obstructive jaundice was associated with reduced overall survival and increased postoperative morbidity. Jaundiced patients with advanced GBC should be considered for surgical resection but need careful evaluation and counseling before undertaking extensive surgical resection.
