A 77-year-old woman with refractory multiple myeloma was treated with a 4-day continuous intravenous infusion of vincristine and doxorubicin and 4 days of oral dexamethasone. Nine days after her second cycle she presented with lethargy and weakness associated with hyponatremia. Evaluation revealed the syndrome of inappropriate secretion of antidiuretic hormone, which was attributed to the vincristine infusion. After normal serum sodium levels returned, further doxorubicin and dexamethasone chemotherapy without vincristine did not produce this complication.

From January 1984 to March 1987, eleven cases of multiple myeloma were registered in the Department of Radiotherapy, Safdarjang Hospital, New Delhi, giving an incidence of more than three cases per year. The cases had age distribution ranging 40-90 years, the youngest being 40 years and oldest 85 years. The majority were in their sixties. Majority were males. Moderate aches and pain either all over the body or confined to a region along with lethargy and weakness were the commonest presenting symptoms. Lytic bone lesions was the commonest complication. One case had cranial nerve involvement.

Cerebrospinal fluid (CSF) involvement in myeloma is rarely seen. Recently we experienced a case with this lesion. A 70-year-old man developed consciousness level disorder during the course of bronchopneumonia. Neurological examination revealed stuporous consciousness, neck stiffness and Kernig's sign. Immunoelectrophoresis showed monoclonal IgG in serum. CSF which was obtained through lumbar puncture was clear and its pressure was 155 mm H2O. It contained 207 white cells/3 mm3; glucose, 54 mg/dl; and protein, 33 mg/dl. The differential count of the CSF was (in %) monocytes, 48.0; plasma cells, 25.5; neutrocytes, 15.5; and lymphocytes, 11.0. Cytoplasm and nucleus of the plasma cells were in various sizes. Some irregular multiple nuclei, flaming cells and grape cells were also observed in them. The cytoplasm of the plasma cells fluoresced with antisera against lambda chains IgG. The value of immunofluorescent technique in identifying plasma cells in the CSF is emphasized.

A Phase II study of interferon alfa-2a was conducted in 64 patients with multiple myeloma (42 IgG, 16 IgA, 5 Bence-Jones type, and 1 IgD) in a multi-institutional cooperative trial. Partial remission was obtained in 10 (21.3%) of 47 evaluable patients, and minor responses in 5 (10.6%) of 47. Remission was reached at 22 to 89 days (median, 29 days) after the initiation of interferon alfa-2a and lasted 4 to 55 weeks (median, 8 weeks). Side effects were noted in more than two-thirds of patients, and included fever (58%), malaise (20%), anorexia (52%), nausea-vomiting (26%), lethargy (2%), and myelosuppression (56%). They were all reversible on discontinuation of interferon alfa-2a. Antibody to interferon alfa-2a was detected in 1 of 20 patients tested during the course of treatment. Thus, interferon alfa-2a was effective in multiple myeloma, producing unequivocal response in 21.3% of patients without unacceptable side effects.

A phase II study of recombinant human leukocyte A interferon was conducted in 64 patients with multiple myeloma in a multi-institutional cooperative trial. Partial remission was achieved in ten (21.3%) of 47 evaluable patients and minor response was observed in five (10.6%). Side effects were noted in more than two-thirds of the patients. They included fever (58%), malaise (20%), anorexia (52%), nausea and vomiting (26%), lethargy (2%), and myelosuppression (56%). An antibody to recombinant human leukocyte A interferon was detected in one of 20 patients.

Cold insolubility of a serum IgA cryoimmunoglobulin was found to be inhibited by the addition of 1.5 mM sodium decanedicarboxylate in vitro. The patient with the cryoglobulin had advanced multiple myeloma complicated by severe hyperviscosity that caused lethargy and episodic loss of consciousness. Decanedicarboxylic acid administered orally resulted in transient relief of symptoms and the loss of cryoprecipitability of the paraprotein. Further in vitro studies revealed that sodium salts of long-chain monocarboxylic acids with a minimum of eight carbons, and dicarboxylic acids with a minimum of 12 carbons inhibited cryoprecipitation. Salts of short-chain carboxylic acids, by contrast, enhanced cryoprecipitation. Sodium phenolate and sodium salts of benzoic acid, 2,4-DNP, phenylpropionic acid, and salicylic acid were also inhibitory. These latter compounds, which have a ring structure, did not cause precipitation at any concentration. It was demonstrated that the presence of a free carboxylic group was required for these activities; conversion of carboxylic acid to amide resulted in the loss of both the inhibitory and cryoprecipitation-enhancing effects. Normal plasma, or plasma from five other patients who had IgG, IgM, or mixed-type cryoglobulinemia, were not affected by any of these compounds. It is suggested that in selected cases of hyperviscosity syndrome associated with cryoglobulinemia, some of these compounds, especially monocarboxylic acids with appropriate chain lengths, or those with a ring structure, may have therapeutic applications.

A 15-year-old Dutch warmblood mare was presented because of lethargy, which had been present for several weeks, and severe anaemia. Total protein was high and serum electrophoresis revealed a monoclonal peak in the alpha-2 region. Monoclonal immunoglobulin, IgG(T), was detected by immuno-electrophoresis in serum and urine. Postmortem examination revealed a relatively large number of plasmacytoid cells in the bone marrow and a monotonous population of plasmacytoid cells in the spleen. These findings are suggestive of a plasma cell myeloma.

Multiple myeloma is a rare neoplasm in cats. Common presenting signs (e.g., lethargy, anorexia, weight loss) usually are nonspecific. Two cats with multiple myeloma were presented with primary complaints of lameness; one had femoral osteolytic lesions, and the other likely had hyperviscosity syndrome. The cat with osteolytic lesions was treated with chemotherapy; the primary lesion responded, but the neoplasia metastasized.

A patient presented with lethargy, nausea and diarrhoea and had a 10-year history of neurological symptoms in his legs. He was found to have renal failure. Investigations demonstrated a longstanding plasmacytoma of the sacrum and progression to myeloma. Such an indolent course for plasmacytoma is rare. A review of the clinical case and management of solid plasmacytomas is presented.

Severe hypercalcemia is a life-threatening medical emergency. It is most commonly caused by malignant tumors, but can also be caused by primary hyperparathyroidism or less often by a dysregulated production of active vitamin D in granulomatous disorders. Symptoms include nausea, vomiting, renal insufficiency, severe dehydration, lethargy, confusion, and even coma. Severity of symptoms, calcium concentrations, and the overall status of the patient are important considerations in selecting appropriate therapy. Hydration to correct volume depletion is the cornerstone of acute therapy. Loop diuretics may be added to saline hydration after extracellular fluid volume has been replenished to enhance urinary calcium excretion and mitigate fluid overload from rehydration. Calcitonin and intravenous infusion of bisphosphonates reduce serum calcium levels by interfering with calcium release from the skeleton. Dialysis with a low or zero calcium dialysate is reserved for patients who are refractory to these measures. Corticosteroids are effective with hypercalcemia due to increased vitamin D levels and in multiple myeloma.
