A 13-year-old castrated domestic shorthair cat was examined because of fever, anorexia, and dermatologic lesions. Crusting, erythema, and well-demarcated purple discoloration of the foot pads and the tips of the pinnae, nose, and tail were seen. A white flocculent precipitate was detected in cooled serum. This precipitate dissolved upon rewarming, consistent with a cryoglobulin. Hypercalcemia, high alanine and aspartate aminotransferase activities, thrombocytopenia, and a monoclonal IgG gammopathy were found. Numerous hepatic nodules were detected by means of abdominal ultrasonography. Cytologic evaluation of fine-needle aspirates of the liver and spleen revealed numerous plasma cells, and evaluation of a bone marrow aspirate revealed plasmacytosis. A diagnosis of multiple myeloma and monoclonal IgG cryoglobulinemia was made, and the cat was euthanatized.

Anaemia, manifesting as fatigue, dizziness, dyspnoea and anorexia, is common among patients with cancer. A host of factors, such as neoplastic bone marrow infiltration, impaired haematopoiesis, autoimmune haemolysis, impaired endogenous erthropoietin production and treatment with cytotoxic agents contribute to the underlying pathology. Traditionally, blood transfusions have formed the mainstay of therapy for the treatment of cancer-related anaemia. Numerous clinical trials have subsequently confirmed the safety and therapeutic utility of recombinant human erythropoietin (rHuEPO) in anaemic cancer patients, including those with haematological malignancies, such as multiple myeloma and non-Hodgkin's lymphoma. Indeed, well over 50% of unselected patients treated with rHuEPO can be expected to respond with increases in haemoglobin level and/or elimination of transfusion need. In addition, a low baseline serum erythropoietin level can identify those patients with haematological malignancies having a very high likelihood of responding to rHuEPO therapy. These findings, in combination with the possibility of titrating to a lower, maintenance dose, have improved the cost-benefit relationship and thus support the use of rHuEPO as an appropriate alternative to blood transfusions for the management of anaemic patients with lymphoma and myeloma.

We report a case of amyloidosis associated with K light chain multiple myeloma in a 42-year-old African American man. The patient initially had mild dyspepsia, which rapidly progressed to include anorexia, fulminant hepatic failure, and death within 9 weeks. This is only the fourth reported case of hepatic failure from myeloma-associated amyloidosis and the second reported case of light chain myeloma with amyloidosis resulting in a progressive clinical course of hepatic failure. Our patient was unique in that, despite severe disease, he had mild symptoms without laboratory abnormalities until 2 weeks prior to death.

C-reactive protein (CRP) is a nonspecific but sensitive marker of inflammation. Interleukin-6 (IL-6), IL-1, and tumor necrosis factor alpha induce the synthesis of CRP in hepatocytes. Increased CRP level is considered to be an important risk factor for atherosclerosis, myocardial infarction, peripheral vascular disease, and ischemic stroke. It is positively correlated with weight loss, anorexia-cachexia syndrome, extent of disease, and recurrence in advanced cancer. Its role as a predictor of survival has been shown in multiple myeloma, melanoma, lymphoma, ovarian, renal, pancreatic, and gastrointestinal tumors. Measurement of CRP is simple, cheap, and routine and provides valuable information in palliative care.

The failure-to-thrive syndrome in geriatric patients is marked by social withdrawal, apathy, depression, anorexia, and cognitive impairment. For therapy to be effective, the treatment plan must target several of theseareas. This case report describes one such course of treatment for a patient with multiple myeloma with failure-to-thrive who was successfully treated with modafinil and mirtazapine. By using combination pharmacotherapy, we were able to achieve immediate results in a gravely ill patient.

Interleukin (IL)-6, a pleiotropic cytokine with varied systemic functions, plays a major role in inflammatory processes. It modulates the transcription of several liver-specific genes during acute inflammatory states, particularly C-reactive protein, and controls the survival of normal plasmablastic cells. In addition, IL-6 has been implicated in hematopoiesis as a cofactor in stem cell amplification and differentiation. This article is the first review of clinical studies in the 1990s with anti-IL-6 monoclonal antibodies (mAbs) in the treatment of patients with cancer and related lymphoproliferative disorders. In six clinical studies of mAbs to IL-6 with BE-8 or CNTO 328 in patients with multiple myeloma, renal cell carcinoma, and B-lymphoproliferative disorders, anti-IL-6 mAb treatment decreased C-reactive protein levels in all patients. In most patients, levels decreased below detectable limits. The antibodies were well tolerated, and no serious adverse effects were observed in the vast majority of studies. The fact that anti-IL-6 mAb therapy decreased the incidence of cancer-related anorexia and cachexia may also be useful in the treatment of cancer patients.

Plasma cell leukemia (PCL) is a rare disease and is the least common variant of multiple myeloma accounting for 2-3% of all plasma cell dyscrasias. We report a patient who presented with history of high grade fever, weakness, palpitations, loss of appetite, bone pains and mental confusion for twenty days. Initial evaluation revealed plasmacytosis with blood plasma cell count of 5184/cumm. His hemoglobin (Hb) was 11.3 gm/dl, platelets were 75000/cumm and total leucocyte count (TLC) was 21600/cumm (24% plasma cells). Bone marrow examination revealed >60% plasmablasts. Serum LDH was high at 3117 U/L and serum calcium was also elevated at 13.9 mg/dl. A diagnosis of PCL was made and the patient was started on treatment for hypercalcaemia with Melphalan/Prednisolone regime along with supportive care. Patient deteriorated very rapidly despite treatment and died on the eighth day. A detailed report of this case and a review of PCL is presented here.

Hypercalcemia associated with malignancies is reported in up to 20 to 30% of patients with cancer during the course of the disease, and points to a poor prognosis. Symptoms related to the central nervous system, as progressive mental impairment, stupor and coma, predominate. Alterations in kidney function (water-concentrating defect leading to polyuria) and gastrointestinal tract (anorexia, nausea, vomiting) corroborate to dehydration and a further increase in serum calcium. Cancer-induced hypercalcemia may be classified as: 1) local osteolytic hypercalcemia (LOH), due to marked increase in osteoclastic bone resorption in areas surrounding the malignant cells within the marrow space; 2) humoral hypercalcemia of malignancy, caused by the secretion of parathyroid hormone-related protein (PTHrP) by the malignant tumor; 3) ectopic hyperparathyroidism; 4) 1,25(OH)2 D-secreting tumors. Adequate control of hypercalcemia is necessary to give the patient time to respond to anti-cancer therapy. Volume expansion with saline will correct dehydration, improve glomerular filtration and increase urinary calcium excretion, which may be further stimulated by loop diuretics. Intravenous bisphosphonates are the most effective agents to control hypercalcemia, as they block osteoclastic osteolysis and also have antitumoral effects, decreasing bone metastases. New approaches to control the skeletal manifestations of malignancies are anti-PTHrP and anti-RANKL antibodies, osteoprotegerin, and also proteasome inhibitors in the case of multiple myeloma.

Although a double autologous peripheral blood stem cell transplant (APBSCT) is an effective therapy for patients (pts) with multiple myeloma and extends progression-free survival and overall survival, pts show a continued pattern of recurrent disease. The feasibility and tolerability of thalidomide (Thal) administered in the post-transplantation period as maintenance therapy was tested in 17 pts at a dose of 100 mg/d starting between 3 and 5 months after the second transplantation and continuing either until toxicity precluded further therapy or until pts had disease progression. After a median administration of 13 months (range: 3-26), 76.5% (13 pts) failed to tolerate Thal because of: transiet ischemic attack (three pts), severe fatigue (two), neutropenia (one), piastrinopenia (one), severe opportunistic infectious (two), erectile impotence (one), gastrointestinal toxicity (anorexia with weight loss one), peripheral neuropathy (two). After a median follow-up of 36 months (range: 10-59) from the second transplant, 13 patients attained a CR + near CR (with a conversion rate from 47.1% to 76.5%). In conclusion, Thal as maintenance therapy after double ASCT is associated with low feasibility and high toxicity and could prevent a lengthy use of this antineoplastic agent.

The aim of the study is to review the clinical manifestations and the hematological findings of brucellosis and pancytopenia, with or without hematological malignancies. The records of 202 patients with brucellosis were evaluated retrospectively. Among these cases of brucellosis seen in a 6 year period between April 1999 and June 2005, 30 patients with pancytopenia were identified. The most common manifestation was fever, followed by weight loss, anorexia, malaise, arthralgia, and hepatosplenomegaly. Bone marrow biopsies revealed hypercellularity or normocellularity. The most common findings in the bone marrow evaluation were histiocytic hemophagocytosis and granulomas. Among all cases, we diagnosed 5 hematological malignancies (1 acute myelogenous leukemia, 2 acute lymphoblastic leukemia, and 2 multiple myeloma) concurrently with brucellosis. The clinical symptoms and findings were similar in patients with and without malignancies. In cases with malignancies, the bone marrow biopsy revealed predominant primary disease involvement. Significant increases in ESR and CRP, severe anemia and thrombocytopenia were observed in patients with malignancies. Peripheral blood counts in patients without malignancies returned to normal after antibiotic treatment for brucellosis. However, pancytopenia in two patients with malignancies did not recover because of primary resistant disease. We conclude that while histiocytic hemophagocytosis may be considered as a major cause of pancytopenia, leukemic infiltration can also be an extreme and unusual cause of pancytopenia in patients in whom brucellosis was concurrently diagnosed with hematological malignancies.
