One of the major complications after high-dose methotrexate (HDMTX) infusions is renal damage. We investigated the occurrence of proteinuria after HDMTX administration in children with pediatric malignancies (acute lymphoid leukaemia, osteosarcoma Burkitt's lymphoma). In the period 1989-1990 we gave 52 HDMTX courses to 24 children. During this period, prehydration and extra urinary alkalisation were performed only if the urinary specific gravity was over 1010 or if the urinary pH fell below 7. Using this schedule the mean values obtained for protein extraction were: before the therapy, 0.12 +/- 0.03 g/m2; on day 1 after MTX treatment, 0.38 +/- 0.06 g/m2; and on day 2 after the MTX infusion, 0.39 +/- 0.11 g/m2 (P < 0.01). A significant increase in proteinuria (> 0.2 g/m2 post- vs pretreatment) was detectable in 54% of the patients. In the period 1991-1992 we modified the hydration-alkalisation schedule to include i.v. prehydration for 18-24 h at 3 l/m2/day with a 0.45% NaCl-5% glucose solution along with sodium bicarbonate and posthydration for 72 h with the same solution. On this protocol the mean values determined for the urinary protein content were all in the normal range (pretreatment, 0.03 g/m2/day; day 1, 0.05 g/m2/day; and day 2, 0.08 g/m2/day). These findings were significantly different from the previous results (P < 0.05).

In a series of 2038 paraproteinemic sera, 9 IgD paraproteins (0.44%) were found. Clinical diagnosis of all the 9 was multiple myeloma. One patient had an IgD-lambda plasmacytoma which developed into plasmocellular leukemia. Our series of IgD paraproteins consisted of 6 females and 3 males with a mean age of 58.5 years. The mean concentrations of IgD paraproteins were 6.7 +/- 4.26 g/l and the mean proteinuria was 5.1 +/- 4.76 g/24 h. Eight IgD paraproteins had light chains lambda and one had light chains kappa.

The clinical course of multiple myeloma (MM), ranging from relatively asymptomatic form to frankly aggressive neoplasia, is more variable than that of other hematologic malignancies. The nature of tumor cells and/or the secondary effects of malignancy as anemia, hypercalcemia, and renal failure have shown to correlate with clinical behavior of MM. Prognostic variables include age, degree of anemia, morphologic subtypes, serum creatinine and calcium levels, Bence Jones proteinuria, plasma cell LI%, beta 2MG level, nucleolus-associated J chains and other laboratory prognostic factors. The plasma cell LI% is the most reliable predictor of survival. Analysis of the presenting features and the clinical characteristics indicates that there are several variants of MM with a poor prognosis, including juvenile myeloma, plasma cell leukemia, aggressive myeloma, high LDH myeloma, J chain myeloma, and amylase-producing myeloma. Four relapsing patterns have been pointed out. The appearance of an additional M-component (mutation escape) suggests the terminal or advanced stage of illness. A new lambda-type M-component can be found in patients with kappa-type myeloma. The prognostic significance of Bence Jones escape varies for different stage of illness. Bence Jones escape is an important predictor of the development of overt MM in patients with smoldering MM. The need for clearly established prognostic criteria is imperative for the choice of correct therapeutic strategies.

Induction therapy of promyelocytic leukemia with all-trans retinoic acid is a standard therapy despite significant side-effects. The most important, the "retinoic acid syndrome", consists of a hyperinflammatory reaction with capillary leakage (edema, pleural, and pericardial effusion), infiltration of myeloid cells into internal organs and systemic signs of inflammation. We describe here two cases of another hyperinflammatory reaction during all-trans retinoic acid therapy, the Sweet's syndrome, consisting of infiltrates of the skin and internal organs by neutrophilic granulocytes. Fever, painful erythematous cutaneous plaques, prominent musculoskeletal involvement (myositis, fasciitis), a sterile pulmonary infiltration and intercurrent proteinuria characterized the clinical course of all-trans retinoic acid-associated Sweet's syndrome. Treatment with glucocorticoids led to resolution of the syndrome within 48 h. Three other cases of all-trans retinoic acid-associated Sweet's syndrome without involvement of internal organs, prominent on our cases, were published previously. Recognition of ATRA-associated Sweet's syndrome is of practical importance.

Experimental SLE can be induced in susceptible 129/J mice by immunization with a human anti-DNA antibody bearing a common idiotype designated 16/6 Id. Immunized mice develop autoantibodies, leukopenia, proteinuria, and immune complex deposits in renal glomeruli. Case reports have described clinical improvement in SLE in individuals becoming infected with HIV-1. Because 129/J mice are susceptible to experimental SLE and to infection with the BM5def murine leukemia virus (MuLV) mixture but do not develop the lymphoproliferative/ immunodeficiency disorder known as murine AIDS (MAIDS), we superimposed this infection on immunization with the 16/6 Id. Multiple effects were observed. First, we noted an amelioration in the course of experimental SLE. Second, both in experimental SLE and in BM5def MuLV infection, immunoreactivity to HIV-1 gp120 was demonstrated, although gp120 is not present in the BM5def MuLV viruses. Third, production of autoantibodies characteristically found in SLE, e.g., anti-DNA, anti-RNP, and anti-SSA, was seen in BM5def MuLV-infected mice, demonstrating that an immune response as a consequence of infection had occurred despite the absence of MAIDS induction. We conclude that (1) retrovirus inoculation may ameliorate the course of experimental SLE; and (2) retrovirus inoculation, even in the absence of MAIDS induction, induces an immunologic response which promotes the production of potentially pathogenic autoantibodies.

We report on a patient with an almost 20-year history of B chronic lymphocytic leukemia (B-CLL). During the last 2 years, the patient developed nephrotic syndrome (NS) due to membranous glomerulonephritis (MN), refractory to standard therapeutic regimens. Neither NS nor B-CLL responded objectively to systemic administration of two different combinations of corticosteroids and alkylating agents (chlorambucil, cyclophosphamide). Third-line therapy with cyclosporin A resulted in reduction of proteinuria and improvement of leukemia. Withdrawal of the drug led to an increase in leukocyte count.

Chronic lymphocytic leukemia is a common disease in the elderly but is rarely associated with a nephrotic syndrome. The rarity of this association suggests that leukemic cells may have certain properties or features that may lead to the development of glomerulonephritis. Effective medical treatment of the leukemia may not necessarily allow regression of the nephrotic syndrome; however, the effects of splenectomy on nephrotic proteinuria when associated to chronic lymphocytic leukemia have never been evaluated. We report the case of a 50-year-old male with stage C CD5+ chronic lymphocytic leukemia associated with a nephrotic syndrome due to Type I membranoproliferative glomerulonephritis. Chlorambucil and prednisone were unable to control the leukemia and the nephrotic range proteinuria, and were discontinued because of poor hematologic tolerance. A splenectomy immediately resulted in a spectacular remission of both chronic lymphocytic leukemia and the nephrotic syndrome. Spleen lymphocytes were collected and tested in quantitative flow cytometry for the expression of the main B cell associated markers. They did not exhibit any particular immunophenotypic pattern. This report of a remission of a glomerulonephritis associated with chronic leukemia following splenectomy is evidence of a possible relationship between the two diseases.

Therapy-related leukemia and myelodysplastic syndrome (TRL/MDS) in Japan were analysed in a multi-institution study to assess clinical, cytogenetic aspects, and prognostic factor. From 1985 to 1994, 405 cases of adult TRL/MDS were diagnosed and overall percentage of TRL/MDS in leukemia and MDS was 1.9%. Median age was 61 years old. The median latency from primary malignancies was 53.4 months, which latency was significantly shorter in the patients treated with chemotherapy. Primary malignancies were hematologic in 39%. Common symptoms were fatigue/ weakness and anemia. Chromosome 7,5, and 11 were frequently involved. MLL gene rearrangement were detected in 12 of 64 analysed cases. Overall median survival was 10.0 months. Body weight loss, neurologic abnormality, hypoproteinemia, hypofibrinogenemia, proteinuria, lack of Auer rods, and 5q-were prognostic factors in TRL/MDS. This large population study documented some datas useful for the prevention of TRL/MDS.

We report on a series of 26 patients diagnosed with primary (de novo) plasma cell (PC) leukemia (PCL) in whom we analyzed the clinicobiologic characteristics of the disease together with the immunophenotype, DNA cell content, proliferative index, and numeric chromosomal aberrations of the neoplastic PC, and compared them with 664 multiple myeloma (MM) patients at diagnosis. The median age, sex ratio, and bone lesion extension were similar, but PCL cases displayed a higher prevalence of clinical stage III, extramedullary involvement, and Bence Jones cases, with fewer IgA cases than for MM patients. In addition, according to several prognostic indicators (beta2-microglobulin serum level, proportion of S-phase PCs, proteinuria, calcium serum level, lactate dehydrogenase [LDH] and renal function), the incidence of adverse prognostic factors was significantly higher in PCL versus MM. Immunophenotypic expression was similar for CD38, CD138, CD2, CD3, CD16, CD10, CD13, and CD15, but PCL differed from MM in the expression of CD56, CD9 HLA-DR, CD117, and CD20 antigens. Twenty-two PCL cases were diploid and one was hypodiploid, while most MM cases (57%) showed DNA hyperdiploidy. With the fluorescent in situ hydridization (FISH) technique, 12 of 13 PCL cases displayed the numeric aberrations, -13 (86%), +/-1 (57%), +18 (43%), and -X in women (25%), but they lacked several numeric aberrations usually found in MM such as +3, +6, +9, +11, and +15. PCL cases had a lower overall response to therapy than MM cases (38% v 63%, P =.01332). Among PCL patients, a trend for a worse response was observed in cases treated with melphalan and prednisone (MP) versus polychemotherapy. Overall survival was significantly worse in PCL versus MM patients (8 v 36 months, P <.0001), but it was significantly better in PCL patients treated with polychemotherapy versus MP (18 v 3 months, P =.0137). By contrast, MM patients did not show significant differences in overall survival according to the treatment used, MP or polychemotherapy. Ten variables seemed to predict survival in PCL patients, but only the beta2-microglobulin level and S-phase PCs retained an independent value in multivariate analysis. In summary, our study illustrates that PCs from PCL display singular phenotypic, DNA cell content, and cytogenetic characteristics that lead to a different disease evolution versus MM.

IgE multiple myeloma is a rare disease characterized by a high frequency of Bence-Jones proteinuria and plasma cell leukaemia when compared to other isotypes of monoclonal proteins. Only 35 cases have been reported. We describe a 70-year-old woman with a stage III IgE kappa multiple myeloma presenting with a sacral plasmacytoma. Immunological and biochemical studies showed IgE kappa producing tumoral plasma cells. Serum total IgE was high without clinical symptoms suggesting an hyperIgE syndrome or mast cell activation. The patient underwent surgical removal of the sacral tumor and monthly melphalan-prednisone treatment together with intravenous pamidronate infusions. Magnetic Resonance Imaging (MRI) of the dorsolumbar spine revealed an epidural process leading to T6-T9 radiotherapy. Bone densitometry showed a decreased bone mineral content supporting the management of myeloma-related osteoporosis with bisphosphonate infusions. A good partial response with plateau-phase and increase of bone mineral content was achieved after 1 year of treatment and still persists after a 28 months follow-up.
