Single-Agent Brentuximab as Bridging Therapy for Hodgkin Lymphoma Patients With Hepatic Impairment

Vanishing bile duct syndrome as a presentation of Hodgkin's lymphoma

Vanishing bile duct syndrome is an uncommon condition characterised by the progressive loss and disappearance of bile ducts. It is an acquired form of cholestatic liver disease presenting with hepatic ductopenia (loss of >50% bile ducts in the portal areas). We present a case of vanishing bile duct syndrome as a presentation of Hodgkin's lymphoma who was treated with standard-of-care chemotherapy-doxorubicin, bleomycin, vinblastine and dacarbazine (along with brief administration of rituximab), which led to complete response and normalisation of liver function.

Fulminant Hepatic Failure as the Initial Presentation of Hodgkin Lymphoma in 4 Patients With Human Immunodeficiency Virus

In the era of antiretroviral therapy (ART), Hodgkin Lymphoma (HL) is a common non-AIDS-defining cancer with increasing incidence in people with human immunodeficiency virus (PWH). Through review of these cases, we identify clinical patterns such as declining CD4 count despite ART, hyperbilirubinemia and recurrent fever, which preceded diagnosis. Identifying these important signs and symptoms may lead to earlier diagnosis and initiation of therapy. Fulminant hepatic failure limits the ability to give standard of care chemotherapy, likely jeopardizing outcomes in this patient population. Alternative bridging therapies should be considered until hepatic function improves.

Administration of brentuximab vedotin to a Hodgkin lymphoma patient with liver dysfunction due to vanishing bile duct syndrome resulting in a partial response without any severe adverse events

Vanishing bile duct syndrome (VBDS) is a rare hepatic disorder which leads to liver failure as a result of progressive destruction of the intrahepatic bile ducts. There are no treatment modalities for VBDS itself and severe hepatic dysfunction restricts the treatment of underlying diseases. We safely treated a case of classic Hodgkin lymphoma (HL) with VBDS using brentuximab vedotin (BV). The patient was treated with 5 cycles of reduced BV and a partial metabolic response was obtained. Moreover, a standard dose of BV for another 5 cycles was accomplished with minimal adverse events. Our experience indicates that BV could be a treatment option for classic HL with VBDS.

A successful initiation of treatment of Hodgkin's lymphoma with adriamycin-bleomycin-vinblastine-dacarbazine dose reduction in a patient with fulminant hepatic failure and co-infection with human immunodeficiency virus and hepatitis B

INTRODUCTION

Hodgkin lymphoma is a highly curable lymphoproliferative malignancy with an overall relative survival rate of 87.4%. It is characterized by multinucleated Reed-Sternberg cells which are mostly derived from B cells in the germinal center.

CASE REPORT

We present a case of a 40-year-old gentleman with acquired immunodeficiency syndrome who presented with Stage 4b Hodgkin lymphoma complicated with fulminant hepatic failure and direct hyperbilirubinemia. The initial presentation of Hodgkin lymphoma as cholestatic jaundice is extremely rare.

MANAGEMENT AND OUTCOME

Though the survival rate with chemotherapy is high, the fulminant hepatic failure made the situation challenging with the use of chemotherapeutic regimens that require hepatic excretion. He received dose reduced adriamycin-bleomycin-vinblastine-dacarbazine regimen [doxorubicin 12.5 mg (6.75 mg/m²), bleomycin 18 units (10 units/m²), vinblastine 3 mg (1.5 mg/m²), dacarbazine 380 mg (190 mg/m²)] as well as bictegravir/emtricitabine/tenofovir alafenamide since admission for treatment of human immunodeficiency virus and hepatitis B. He started responding with the first cycle of dose reduced adriamycin-bleomycin-vinblastine-dacarbazine regimen with bilirubin levels trended down and normalized as well as his clinical condition improved. He received the full dose of adriamycin-bleomycin-vinblastine-dacarbazine on day 15.

DISCUSSION

Our case report emphasizes that the early usage of dose reduced adriamycin-bleomycin-vinblastine-dacarbazine regimen can restore hepatic function and can achieve improvement in hepatic function allowing the delivery of full-dose chemotherapy.

Optimizing outcomes in relapsed/refractory Hodgkin lymphoma: a review of current and forthcoming therapeutic strategies

The outcome of patients with relapsed/refractory classical Hodgkin lymphoma (rr-cHL) has improved considerably in recent years owing to the approval of highly active novel agents such as brentuximab vedotin and Programmed Death-1 (PD-1) inhibitors. Although no randomized trials have been conducted to provide formal proof, it is almost undisputable that the survival of these patients has been prolonged. As autologous stem-cell transplantation (SCT) remains the standard of care for second-line therapy of most patients with rr-cHL, optimization of second-line regimens with the use of brentuximab vedotin, or, in the future, checkpoint inhibitors, is promising to increase both the eligibility rate for transplant and the final outcome. The need for subsequent therapy, and especially allogeneic SCT, can be reduced with brentuximab vedotin consolidation for 1 year, while pembrolizumab is also being tested in this setting. Several other drug categories appear to be active in rr-cHL, but their development has been delayed by the appearance of brentuximab vedotin, nivolumab and pembrolizumab, which have dominated the field of rr-cHL treatment in the last 5 years. Combinations of active drugs in chemo-free approaches may further increase efficacy and hopefully reduce toxicity in rr-cHL, but are still under development.

Multi-Organ Failure as the Initial Presentation of Lymphocyte-Depleted Hodgkin Lymphoma in Two Patients with Human Immunodeficiency Virus

Patients with HIV-associated lymphocyte-depleted Hodgkin lymphoma (HIV-HL) often present with advanced, extranodal disease and aggressive clinical features, limiting definitive therapeutic intervention. Here we report two patients with HIV-HL who presented with multi-organ dysfunction as an initial manifestation of their malignancy. Both were initially treated with brentuximab vedotin (BV), which led only to a temporary partial response, highlighting the challenges of treatment. One patient was eventually started on nivolumab and responded very well to the immune checkpoint inhibitor. To our knowledge, this is the first case to describe successful use of nivolumab in a patient with relapsed lymphocyte-depleted HIV-HL. Prompt recognition of multi-organ dysfunction as an initial presentation of lymphocyte-depleted HIV-HL is essential to ensure rapid provision of therapy. While use of BV remains a reasonable option, earlier introduction of immunotherapy in the treatment of HL may provide an additional option in critically ill patients with lymphocyte-depleted HIV-HL.

Liver Involvement in Hodgkin's Lymphoma: Types of Injuries and Therapeutic Implications

The hepatocytolysis raises questions on following therapeutic conduct when it occurs during chemotherapy for Hodgkin's lymphoma, expression of its liver toxicity. But the onset of primary liver Hodgkin's lymphoma, including the form manifested by acute liver failure, poses even greater problems, as in the case of occurrence of vanishing bile duct syndrome - expression of a paraneoplastic syndrome, hemophagocytic lymphohistiocytosis, peliosis hepatis or association of lymphoma with infection with hepatitis viruses or human immunodeficiency virus or different autoimmune diseases. This review summarizes the clinical experience acquired on the relationship between Hodgkin's lymphoma and liver, from the point of view of clinical manifestations, used treatments and clinical evolution. Suggestions on the course of treatment in patients with Hodgkin's lymphoma and liver damage have been formulated starting from the metabolism and elimination of chemotherapy drugs and taking into account the clinical experience of published clinical trials and cases. This review is a synthesis of knowledge obtained in this field, during the time, of therapeutic possibilities and limits, and formulates potential future milestones for research.
