ABSTRACT A 55-year-old woman with primary Immunoglobulin light chain (AL) systemic amyloidosis died due to spontaneous rupture of her liver following treatment with high-dose melphalan and autologous stem cell transplant (HDM/SCT). She was first diagnosed after developing nephrotic-range proteinuria. Spontaneous rupture of her liver occurred 10 days after treatment with HDM/SCT and was complicated by septic shock. She was not eligible for surgical intervention and died shortly after. Amyloid fibrils were extracted from the autopsied liver sample (05-135L) and the biochemical nature of the fibrils was analyzed using electrophoretic and immunohistochemical techniques. Our testing showed that the fibrils were composed of immunoglobulin lambda light chains that were not glycosylated. While the liver is often involved in AL amyloidosis, this is the first documented case of a spontaneous hepatic rupture in a patient during treatment with HDM/SCT. A literature review of spontaneous liver rupture in patients with amyloidosis is presented.

    ABSTRACT: AL amyloidosis is the most common form of systemic amyloidosis and is associated with an underlying plasma cell dyscrasia. The disease is often difficult to recognize because of its broad range of manifestations and, what are often, vague symptoms. Recent diagnostic and prognostic advances include the serum free light chain assay, cardiac magnetic resonance imaging, and serologic cardiac biomarkers. Treatment strategies that have evolved during the past decade are prolonging survival and preserving organ function in patients with this disease. This review outlines the role of high dose melphalan and stem cell transplantation in the treatment of AL amyloidosis.

    ABSTRACT: High-dose melphalan chemotherapy and autologous peripheral blood stem cell transplantation has been shown to result in durable hematologic response and prolonged overall survival in systemic AL amyloidosis. In this retrospective study, we evaluated clinical and hematologic responses in 69 patients with predominant liver involvement who were treated with high-dose intravenous melphalan and autologous stem cell transplantation from 1998 to 2006. Nine patients (13%) died from treatment-related mortality, similar to patients without hepatic involvement. The overall survival was 81% at one year and 61% at five years, by Kaplan-Meier estimates. A hematologic complete response was achieved by 53% (31/58) of patients at one year. A hepatic response occurred in 57% (33/58) at one year after high-dose intravenous melphalan and autologous stem cell transplantation and 63% (19/30) at two years after high-dose intravenous melphalan and autologous stem cell transplantation. In conclusion, hepatic disease improves in almost 2/3 patients treated with high-dose intravenous melphalan and autologous stem cell transplantation who have a complete or partial hematologic response to treatment.

    ABSTRACT: Spontaneous bleeding due to a non traumatic liver rupture is a rare occurrence. However, it is associated with high morbidity and mortality. Usually the predisposing factors are like Hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome in pregnant women and other liver diseases. It is generally diagnosed by imaging studies such as ultra sonogram or computerized tomogram (CT). Due to its rarity no standard treatment has been described. Here, we report two cases of spontaneous rupture of normal liver in two young males. They presented with severe shock and hemoperitoneum. The diagnosis was confirmed by CT. They were managed surgically. In case of hemoperitoneum, spontaneous liver rupture should be considered. An early aggressive resuscitation and appropriate intervention gives better outcome.
