Vanishing bile duct syndrome arising in a patient with T-cell-rich large B-cell lymphoma

Gallbladder non-Hodgkin's lymphoma: Case report

•

The patient was hospitalized for “intermittent fever, abdominal pain for 19 days” and then underwent laparoscopic cholecystectomy. After the operation, the patient’s condition deteriorated and eventually died. Postoperative pathological diagnosis confirmed gallbladder non-Hodgkin’s lymphoma.

•

Gallbladder non-Hodgkin’s lymphoma is very rare, and this case also includes hemophagocytic syndrome and bile duct disappearance syndrome, which is rare. This case is described from the onset of the patient to the hospital visit and postoperative conditions.

•

Bile duct disappearance syndrome (VBDS) is a syndrome characterized by reduced intrahepatic bile ducts as a pathological feature and cholestasis as the main clinical manifestation.

•

Hemophagocytic syndrome (HPS) is a group of heterogeneous diseases characterized by over-inflammatory responses due to hereditary or acquired immunodeficiency.

Introduction

Extrahepatic biliary non-Hodgkin’s lymphoma (EBNHL) is rare, with a prevalence of 0.6% of malignant biliary tumors. Primary biliary non-Hodgkin’s lymphoma accounts for 0.4% of extranodal non-Hodgkin’s lymphoma (NHL), accounting for approximately 0.016% of all NHL cases. The patient presented with typical bile duct disappearance syndrome. The late performance is a bloodthirsty syndrome.

Presentation of case

This patient was admitted to the hospital with “intermittent fever, abdominal pain for 19 days”. The relevant laboratory tests showed severe infection. The patients were treated according to abdominal infection, and then laparoscopic cholecystectomy was performed. After the operation, the patient's condition did not relieve and further deteriorated. Postoperative patient performance was not based on preoperative estimates, and surgery did not achieve the desired results. Postoperative pathological diagnosis confirmed gallbladder non-Hodgkin’s lymphoma. The patient eventually died.

Discussion

Non-calculus inflammation occurs more frequently in the gallbladder. Non-calculus infections are generally caused by bile stasis and ischemia, resulting in bacterial reproduction and reduced blood supply, and gangrene and perforation of the gallbladder are more likely to occur. This patient is also diagnosed and treated according to this idea. The development after surgery completely exceeded our expectations. Gallbladder non-Hodgkin’s lymphoma is very rare, and this case also includes hemophagocytic syndrome and bile duct disappearance syndrome, which is rare.

Conclusion

Malignant lymphoma of the extrahepatic biliary system is extremely rare, and its clinical manifestations are easily misdiagnosed. At the same time, non-calculous cholecystitis with fever, jaundice and hepatosplenomegaly should be considered.

Revaluation of vanishing bile duct syndrome

Vanishing bile duct syndrome (VBDS) can result from multiple etiologies, including congenital and genetic diseases, ischemic causes, neoplastic disorders, infections, immune disorders, drugs, idiopathic adulthood ductopenia (IAD) and so on. Recently, lymphoma, HIV/AIDS and drugs were identified to be major etiologies in the reported cases, some of which presented complex clinical course and were contributed by more than one etiological factor. Hepatic biopsy must be done for the diagnosis of VBDS and immunohistochemical staining for cytokeratin 7 (CK7) and CK19 has contributed to the establishment of diagnosis of VBDS. VBDS can be usually treated with symptomatic and supportive therapy, etiological therapy, liver transplantation, ursodeoxycholic acid and immunosuppressive agents. Glucocorticoids can be tried to switch to mycophemolate mofeil or tacrolimus when their effects are poor or side effects are severe. Severe cases ought to receive multimodality therapy besides plasmapheresis.

Vanishing bile duct syndrome and immunodeficiency preceding the diagnosis of Hodgkin lymphoma

Vanishing bile duct syndrome (VBDS) in association with Hodgkin lymphoma (HL) is well described but not well understood. We report an unusual case of a 75-year-old patient presenting with biopsy-proven VBDS and immunodeficiency, without identifiable cause, which showed a waxing and waning course, culminating in the development of HL 18 months later. To our knowledge, this is the first adult case in which VBDS preceded the diagnosis of HL by such a long period.

Trial Watch: Therapeutic vaccines in metastatic renal cell carcinoma

Despite the renaissance of cancer immunotherapy, no novel immunotherapy has been approved for the treatment of renal cell cancer (RCC) since the availability of recombinant cytokines (interleukin-2, interferon-α). All vaccine trials have failed to meet their endpoints although they have highlighted potential predictive biomarkers (e.g., pre-existing immune response, hematological parameters, tumor burden). Recent advances in immunomodulatory therapies have prompted the study of combination treatments targeting the tumor immunosuppressive microenvironment consisting of regulatory T-cells (Treg), myeloid suppressor cells, and cytokines. Approaches under investigation are use of inhibitors to curb the overexpression of immune checkpoint ligands by tumor cells (e.g., anti-CTLA-4, anti-PD-1/PD-L1) and exploiting the immunomodulatory effects of anti-angiogenic agents that are the current standard of metastatic RCC care. Phase III trials are focusing on the possible synergy between therapeutic vaccines (e.g., IMA-901 and AGS-003) and anti-angiogenic agents.

Biliary complications after liver transplantation

Biliary complications (BCs) remain one of the most outstanding factors influencing long-term results after orthotopic liver transplantation. The authors carried out a systematic overview of 1720 papers since 2008, and focused on 45 relevant ones. Among 14,411 transplanted patients the incidence of BCs was 23%. Biliary leakage occurred in 8.5%, biliary stricture in 14.7%, mortality rate was 1-3%.

RISK FACTORS

preoperative sodium level; p = 0.037, model of end-stage liver disease score >25; p = 0.048, primary sclerosing cholangitis; p = 0.001, malignancy; p = 0.026, donor age >60, macrovesicular graft steatosis; p = 0.001, duct-to-duct anastomosis; p = 0.004, long anhepatic phase; p = 0.04, cold ischemic time >12 h; p = 0.043, use of T-tube; p = 0.032, insufficient flush of bile ducts; p = 0.001, acute rejection; p = 0.003, cytomegalovirus infection; p = 0.004 and hepatic artery thrombosis; p = 0.001. The management was surgical in case of biliary leakage, and interventional radiology or endoscopic retrograde cholangiopancreatography in case of biliary stricture. Mapping of miRNA profile is a new field of research. Nemes-Doros score is a useful tool in the estimation of hepatic artery thrombosis. Management of BCs requires a multidisciplinary expert team.

Complete remission of paraneoplastic vanishing bile duct syndrome after the successful treatment of Hodgkin's lymphoma: a case report and review of the literature

BACKGROUND

Vanishing bile duct syndrome has been associated with different pathologic conditions (adverse drug reactions, autoimmune diseases, graft versus host disease, and cancer). Though its causes are unknown, an immune-related pathogenesis is the most likely one. Vanishing bile duct syndrome can evolve to hepatic failure and, eventually, to death. The treatment is uncertain, but it needs the resolution of the underlying pathologic condition.

CASE PRESENTATION

We describe the association of Hodgkin's lymphoma with a syndrome characterized by cholestasis, aminotransferase elevation and an histological picture of bile duct loss. All other causes of hepatic function impairment were excluded (in particular, drugs, viral and autoimmune related diseases) eventually leading to the diagnosis of vanishing bile duct syndrome. Despite the fact that the dysfunction is not caused by hepatic Hodgkin's lymphoma involvement, liver impairment can limit the optimal therapy of Hodgkin's lymphoma. A treatment consisting of ursodeoxycholic acid, prednisone, and full dose chemotherapy restored hepatic function and achieved complete and long-lasting remission of Hodgkin's lymphoma.

CONCLUSION

We reviewed all case reports showing that vanishing bile duct syndrome is a dismal paraneoplastic syndrome being fatal in a high proportion of patients if not adequately treated. Indeed, this syndrome requires both an early recognition and an appropriate aggressive treatment consisting of full dose upfront chemotherapy which is the only way to achieve a resolution of the vanishing bile duct syndrome. Delayed or reduced intensity treatments unfavorably correlate with survival.

Immunotherapeutic strategies for the treatment of renal cell carcinoma: where are we now?

Immunotherapy with cytokines was the first effective treatment in metastatic renal cell carcinoma (mRCC). Long-term responders and complete remissions were observed, but efficacy in the overall population was limited with the consequence that targeted agents replaced cytokines. The discovery of tumor associated antigens as direct targets paved the way from theses rather unspecific to specific immunotherapeutic strategies, which are discussed in this review. Autologous or dendritic cell (DC) based tumor vaccination with vitespen or AGS-003, adoptive T-cell transfer and synthetic peptide vaccination with IMA901 are new and promising approaches. Besides that the more passive strategies of antibody dependent cytotoxicity with the VEGF antibody bevacizumab or the carbonic anhydrase IX antibody girentuximab are discussed. Immunomodulation by cyclophosphamide, tyrosine kinase inhibitors or nivolumab, which targets the PD-1 axis, further promote T-cell activation and combinatory strategies with these agents are outlined.
