Clinical Utility of Personalized Serum IgG Subclass Ratios for the Differentiation of IgG4-Related Sclerosing Cholangitis (IgG4-SC) from Primary Sclerosing Cholangitis (PSC) and Cholangiocarcinoma (CCA). J Pers Med 2022; 12:jpm12060855. [PMID: 35743640 PMCID: PMC9225113 DOI: 10.3390/jpm12060855] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2022] [Revised: 05/10/2022] [Accepted: 05/21/2022] [Indexed: 11/16/2022] Open
Abstract
Background: The differential diagnosis of immunoglobulin G4-sclerosing cholangitis (IgG4-SC) from primary sclerosing cholangitis (PSC) or cholangiocarcinoma (CCA) is important. In this study, we aimed to find the best combinations of serum IgG subclasses and IgG4 levels for differentiating IgG4-SC from PSC or CCA. Methods: In total, 31 patients with IgG4-SC, 27 patients with PSC, and 40 patients with CCA were enrolled from 2003 to 2017 at a single tertiary referral center. We retrospectively assessed the IgG4, IgG4/IgG1, IgG4/(IgG1+IgG3), and (IgG4+IgG2)/(IgG1+IgG3) in each of the patients. ROC curves were established to obtain the optimal cutoff value for each parameter. McNemar’s test was used to compare the sensitivities, specificities, and accuracies of diagnostic algorithms. Results: In differentiating IgG4-SC from PSC, the accuracies of IgG4/IgG1 ≥ 0.087 and of IgG4/(IgG1+IgG3) ≥ 0.081 were significantly higher than that of IgG4 ≥ 135 mg/dL alone (78% vs. 66%, p = 0.025). Serum IgG4 ≥ 52 mg/dL showed the best accuracy for differentiation of IgG4-SC from CCA, with a sensitivity and specificity of 80% and 82%, respectively, but this was statistically not significant (p = 0.405). Conclusions: The serum IgG4/IgG1 or IgG4/(IgG1+IgG3) level may help to differentiate IgG4-SC from PSC. IgG4 alone is the most accurate serologic marker for the differentiation of IgG4-SC from CCA.

Abstract
Sclerosing cholangitis (SC) is defined as a condition with progressive stenosis and destruction of the bile ducts due to diffuse inflammation and fibrosis and currently includes three categories: primary sclerosing cholangitis (PSC), secondary cholangitis, and IgG4-related sclerosing cholangitis (IgG4-SC). SC categories share similar clinical features, such as cholestasis. Patients with SC present with cholestatic symptoms, including jaundice and pruritus, and blood tests reveal elevation of cholestatic enzymes. Cholangiography, endoscopic or magnetic, is inevitably required for making a diagnosis. Although the presentation of IgG4-SC and PSC are similar, the comorbidities, treatment response, and outcomes differ significantly, and therefore, it is strongly advisable to be familiar with these two diseases to make a correct diagnosis. Differentiation of cholangiocarcinoma from IgG4-SC and PSC is also extremely important. In this review, the clinical characteristics, comorbidities, treatment and outcomes of IgG4-SC and PSC will be outlined based on experience mainly from Japan.

Abstract
Immunoglobulin (Ig)G4-related sclerosing cholangitis (IgG4-SC) is a biliary tract manifestation of IgG4-related diseases (IgG4-RD); a subgroup of SC defined as a condition with progressive stenosis and destruction of the bile ducts due to diffuse inflammation and fibrosis. IgG4-SC is clinically characterized by the (a) chronic elevation of cholestatic enzyme levels, (b) significant elevation of serum IgG4 levels, (c) diffuse or segmental narrowing of intra and/or extra hepatic bile ducts with thickening of the bile duct wall in imaging studies, (d) marked lymphoplasmacytic and IgG4-positive plasma cell infiltration and fibrosis in histology, (e) presence of IgG4-RD in other organs, mainly involving autoimmune pancreatitis, and (f) excellent response to corticosteroids. The diagnosis of IgG4-SC is based on a combination of these findings. Although the IgG4-SC diagnosis is different from that of primary sclerosing cholangitis (PSC) or biliary and pancreatic malignancies, it is extremely important to diagnose or suspect IgG4-SC appropriately; as the incorrect diagnosis of PSC or malignant diseases may lead to the progression of fibrosis in patients due to untreated chronic cholestasis, or to unnecessary major surgical resections. Although its etiology remains unclear, recent studies of IgG4-SC have attempted to clarify the roles of the IgG4 molecule and novel autoantibodies detected in patients with IgG4-SC.

Abstract
BACKGROUND Immune-mediated cholangiopathies comprise primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC) and IgG4-associated cholangitis (IAC). A common feature is the progressive destruction of bile ducts leading to cholestasis with fibrosis and cirrhosis of the liver over time. The diseases are mostly identified during routine laboratory testing. Clinical signs and symptoms such as pruritus, fatigue or jaundice are infrequent in the early stage. DIAGNOSIS The diagnostic work-up involves the patient's history, physical examination, serological tests, abdominal ultrasonography, magnetic resonance cholangiopancreatography (MRCP) and, where necessary, liver biopsy and genetic testing. THERAPY Ursodeoxycholic acid (UDCA) is an effective treatment of PBC. Second-line therapies in addition to UDCA for incomplete UDCA responders are obeticholic acid (OCA) and bezafibrate, whereby only OCA has received approval for this indication from American (Federal Drug Administration) and European (European Medicines Agency) authorities. In PSC, UDCA improves prognostic markers; dominant bile duct strictures are treated with endoscopic balloon dilatation. Despite therapy, liver transplantation is frequently necessary for PSC. The risk of developing cholangiocarcinoma, colon cancer, and gallbladder cancer is increased for patients with PSC. In contrast to PBC and PSC, IAC responds well to corticosteroids. Disease relapse, however, is common, making long-term treatment with low-dose prednisolone or azathioprine necessary.

Abstract
Autoimmune hepatitis (AIH) is characterized by elevated serum aminotransferases, immunoglobulin G, autoantibodies, and interface hepatitis, in the absence of a known diagnosis. Presentation is varied. Therapy is with immunosuppression. There is inflammation of the intrahepatic and/or extrahepatic bile ducts in Sclerosing cholangitis (SC) and when associated with inflammatory bowel disease, it is known as primary SC, with Ursodeoxycholic acid used for therapy. The overlap of clinical, biochemical and histological features of AIH and PSC is known as autoimmune sclerosing cholangitis (ASC) or overlap syndrome. Liver transplantation is performed when medical treatment fails and both AIH and PSC may recur post-transplantation.

Abstract
Primary sclerosing cholangitis is a rare, chronic cholestatic liver disease characterised by intrahepatic or extrahepatic stricturing, or both, with bile duct fibrosis. Inflammation and fibrosis of bile ducts and the liver are followed by impaired bile formation or flow and progressive liver dysfunction. Patients might be asymptomatic at presentation or might have pruritus, fatigue, right upper quadrant pain, recurrent cholangitis, or sequelae of portal hypertension. The key diagnostic elements are cholestatic liver biochemistry and bile duct stricturing on cholangiography. Genetic and environmental factors are important in the cause of the disease, with the intestinal microbiome increasingly thought to play a pathogenetic role. Approximately 70% of patients have concurrent inflammatory bowel disease and patients require colonoscopic screening and surveillance. Primary sclerosing cholangitis is associated with increased malignancy risk and surveillance strategies for early cholangiocarcinoma detection are limited. No single drug has been proven to improve transplant-free survival. Liver transplantation is effective for advanced disease but at least 25% of patients develop recurrent disease in the graft.

Abstract
In most cholestatic liver diseases the primary cholestasis-causing lesions are located in the biliary tree and may be of (auto)immune origin. Bile salts are responsible for the secondary toxic consequences. Bile salt and nuclear hormone directed therapies primarily aim at improving this secondary toxic injury. In primary biliary cholangitis, trials show statistically significant responses on biochemical endpoints. Preclinical studies suggest that FXR- and PPAR-agonists, inhibitors of the apical sodium-dependent bile salt transporter (ASBT-inhibitors) and the C23 UDCA derivative nor-UDCA are promising agents for the treatment of primary sclerosing cholangitis (PSC). Area covered: Pharmaceuticals that interfere with bile salt signaling in humans for the treatment of chronic cholestatic liver disease are reviewed. Expert commentary: Nuclear hormone receptors, bile salt transport proteins and receptors provide targets for novel therapies of cholestatic liver disease. These drugs show positive results on biochemical endpoints. For histological endpoints, survival and transplant-free survival, long-term trials are needed. For relief of symptoms, such as fatigue and pruritus, these drugs have yet to prove their value.

Abstract
BACKGROUND & AIMS Immunoglobulin G4 sclerosing cholangitis (IgG4-SC) is a biliary tract manifestation of IgG4-related systemic disease. We investigated the demographics, clinical features at presentation, treatment response, and outcomes of IgG4-SC using data from a large-scale survey in Japan. METHODS We performed a retrospective cohort study of 527 patients with IgG4-SC (436 female; median age, 66.2 years; range, 23-89 years) in Japan from 2000 to 2015. Data on patient demographics, presentation, treatment response, and outcomes were collected from questionnaires given to patients at 211 referral centers in Japan in 2015. Patients were diagnosed with IgG4-SC based on the clinical diagnostic criteria established by the Japanese Biliary Association in 2012. Patients were followed for a median of 4.1 ± 3.1 years. Survival was assessed using the Kaplan-Meier curve and log-rank test. RESULTS Symptoms at presentation included jaundice (35% of patients) and pruritus (13% of patients); 28% of patients were asymptomatic. It was extremely rare for patients with IgG4-SC to present with symptoms of decompensated cirrhosis. At presentation, serum levels of IgG4 were increased (>135 mg/dL) in 84% of patients. Response to prednisolone was excellent in 90% of patients. No patients received liver transplants, and cholangiocarcinoma was found in only 4 patients (0.7%). Restenosis of bile ducts was observed in 19% of patients but did not affect overall survival. CONCLUSIONS In a retrospective cohort study of 527 patients with IgG4-SC in Japan, we found the disease to be benign. Most patients (90%) respond to treatment with prednisolone and few develop decompensated cirrhosis or cholangiocarcinoma.

Abstract
There is increased interest and recognition of the clinical variants of Sclerosing Cholangitis (SC) namely IgG4-SC, PSC/AIH overlap and PSC. For most Centers, the characteristic of IgG4-SC has not been thoroughly clinically compared with other sclerosing cholangitis variants. Further there are relatively few PSC/AIH overlap patients and the clinical outcome is not well characterized, especially for the PSC/AIH overlap syndrome. Our objective herein is to clarify the differences and similarities of the natural history of IgG4-SC, the PSC/AIH overlap and PSC alone. We also place in perspective the diagnostic value of serum IgG4 for IgG4-SC and investigate biomarkers for predicting the prognosis of sclerosing cholangitis. In this study, we took advantage of our large and well-defined patient cohort to perform a retrospective cohort study including 57 IgG4-SC, 36 PSC/AIH overlap patients, and 55 PSC patients. Firstly, as expected, we noted significant differences among immunoglobulin profiles and all patients exhibited similar cholestatic profiles at presentation. Cirrhotic events were found in 20 of total 57 IgG4-SC, 15 of 36 PSC/AIH overlap, and 18 of 55 PSC patients. Serum IgG4 was elevated in 92.65% of IgG4-SC patients with an 86% sensitivity and 98% specificity for diagnosis. IgG4-SC patients had a better treatment response at 6-month and 1-year than PSC/AIH patients, while the latter responded better with steroids than PSC patients. Importantly the adverse outcome-free survival of IgG4-SC patients was reduced, unlike earlier reports, and therefore similar to the PSC/AIH overlap syndrome. Serum IgG and total bilirubin were useful to predict long-term survival of IgG4-SC and PSC/AIH, respectively. In conclusion, serum IgG4≧1.25 ULN shows an excellent predictability to distinguish IgG4-SC among SC patients. IgG4-SC appears to be immune-mediated inflammatory process, while PSC/AIH overlap more tends to be cholestatic disease.

Abstract
BACKGROUND Recent research has shown that a substantial number of patients with primary sclerosing cholangitis (PSC) can also have elevated serum/tissue IgG4. The aim of our study was to develop a simple scoring system for the discrimination of IgG4-related sclerosing cholangits (IgG4-SC) from PSC. METHODS Patients with IgG4-SC (n = 39) and PSC (n = 76) who had intrahepatic/hilar strictures were included. Candidate-differentiating variables included patient age, other organ involvement (OOI), inflammatory bowel disease, serum IgG4, and cholangiographic features. A scoring system was developed on the basis of these variables, and its performance was internally validated using a bootstrapping-based method. RESULTS The scoring system in the final model included age (<30 years, 0 points; 30-39 years, 1 point; 40-49 years, 2 points; 50-59 years, 3 points; ≥60 years, 4 points), OOI (no, 0 points; yes, 3 points), and beaded appearance (yes, 0 points; no, 2 points). The patients were classified according to their total score into three categories: 0-4 points, probable PSC; 5-6 points, indicating diagnostic steroid trial; 7-9 points, probable IgG4-SC. The discrimination between IgG4-SC and PSC using the scoring system was excellent (area under the receiver operating characteristic curve, 0.986). CONCLUSIONS A reliable differentiation of IgG4-SC from PSC can be made using the scoring system presented here. We suggest the diagnosis of IgG4-SC at a cutoff of 7 points or higher and the indication of diagnostic steroid trial at 5 or 6 points. External validation of our scoring system is warranted.

Abstract
BACKGROUND Several studies have demonstrated that elevated serum IgG4 levels are associated with poor outcomes of primary sclerosing cholangitis (PSC), but the impact of serum IgG4 levels on PSC remains controversial. In this study, we aimed to determine prognostic factors of patients with PSC and to investigate the association between serum IgG4 levels and the clinical features and prognosis of PSC in a Japanese cohort. METHODS We retrospectively analyzed follow-up data for 435 patients with PSC (UMIN000018438). Patients with distinct etiologies of sclerosing cholangitis including IgG4-related sclerosing cholangitis (IgG4-SC) were excluded from this study. RESULTS Serum IgG4 levels were tested at the time of diagnosis in 216 of 435 patients with PSC, and were elevated in 27 patients (>134 mg/dl, 12.5%). Clinical features at diagnosis were comparable between patients with normal and elevated serum IgG4 levels, with the exception of serum albumin. The overall and liver-transplantation free survival rate was comparable between the groups. Multivariate analysis indicated that age, albumin, and bilirubin, but not IgG4, at the time of diagnosis affected PSC prognosis. CONCLUSIONS The current study showed that serum IgG4 levels at diagnosis do not affect PSC prognosis in a Japanese cohort that excluded patients with IgG4-SC.

Abstract
Immunoglobulin G4 (IgG4)-related sclerosing cholangitis is a special form of cholangitis. As an autoimmune disease, IgG4-related sclerosing cholangitis has no specific clinical manifestations, and its pathogenesis remains unclear. In patients with this disease, serum concentration of IgG4 is elevated, intrahepatic or extrahepatic bile duct stenosis associated with biliary wall thickening is often revealed by biliary imaging, autoimmune diseases such as autoimmune pancreatitis may be present, and massive IgG4 positive plasma cell infiltration and widespread bile duct wall fibrosis are often showed by histopathological examination. It is often difficult to differentiate IgG4-related sclerosing cholangitis from primary sclerosing cholangitis, secondary sclerosing cholangitis and bile duct cancer. However, the disease is sensitive to hormone therapy. This article will review the current advances in research of IgG4-related sclerosing cholangitis.

Abstract
A variety of diseases are included under the umbrella term ‘cholangitis’, including hepatobiliary diseases with an autoimmune pathogenesis (such as primary sclerosing cholangitis, primary biliary cholangitis, and IgG4-associated sclerosing cholangitis) and disease processes associated with intraductal stones and infectious etiologies (such as ascending bacterial cholangitis, recurrent pyogenic cholangitis, and liver fluke-associated cholangitis). Recent advances in the pathophysiologic bases of these disorders, particularly with respect to the autoimmune variety, are allowing improved diagnosis and prognostication as well as providing the opportunity to refine and re-imagine treatment modalities. The aim of this review is to highlight selected advances in cholangitis research that point to novel insights into the pathophysiology, diagnosis, and treatment of this diverse array of disorders.
