Key Points Elderly patients with myeloma are heterogeneous and assessment strategies are needed to define the frailty profile. The proposed frailty score aims to better assess patients and provide them with more suitable therapies.

Insulin binding by insulin antibodies was determined serially in eight menstruating and in twelve pregnant diabetic subjects. No significant variation was noted in the insulin binding values before, during or after menstruation or during or after pregnancy. This constancy of insulin binding was observed despite major and minor changes in insulin needs. No causal relationship could be demonstrated between insulin binding by insulin antibodies and changing insulin requirements. If there is a relationship between the hormonal changes and the alterations in insulin needs during menstruation and pregnancy, the mechanism of this relationship is not mediated through the insulin binding capacity of circulating insulin antibodies.

Purpose To provide an update on recent advances in the management of patients with multiple myeloma who are not eligible for autologous stem-cell transplantation. Methods A comprehensive review of the literature on diagnostic criteria is provided, and treatment options and management of adverse events are summarized. Results Patients with symptomatic disease and organ damage (ie, hypercalcemia, renal failure, anemia, or bone lesions) require immediate treatment. The International Staging System and chromosomal abnormalities identify high- and standard-risk patients. Proteasome inhibitors, immunomodulatory drugs, corticosteroids, and alkylating agents are the most active agents. The presence of concomitant diseases, frailty, or disability should be assessed and, if present, treated with reduced-dose approaches. Bone disease, renal damage, hematologic toxicities, infections, thromboembolism, and peripheral neuropathy are the most frequent disabling events requiring prompt and active supportive care. Conclusion These recommendations will help clinicians ensure the most appropriate care for patients with myeloma in everyday clinical practice.

Clinical risk factors for nephropathy were assessed in a population-based study of Rochester, Minnesota, residents with diabetes mellitus initially diagnosed between 1945 and 1969 (incidence cohort). The 1031 Rochester residents with non-insulin-dependent diabetes mellitus (NIDDM) were followed through their complete medical records in the community to 1 January 1982. The prevalence of persistent proteinuria was 8.2% at the diagnosis of NIDDM. Among those initially free of persistent proteinuria, the subsequent incidence was 15.3/1000 person-yr. Twenty years after the diagnosis of diabetes, the cumulative incidence of persistent proteinuria was 24.6%. A proportional hazards model identified the following risk factors for persistent proteinuria in NIDDM: elevated initial fasting blood glucose (P < .01); older age at onset of diabetes (P < .01); male gender (P = .05); and presence of macrovascular disease (P = .05), diabetic retinopathy (P = .05), or glycosuria (P = .07) at the diagnosis of diabetes. Separate analyses controlling for attained age indicated no association between duration of NIDDM and the incidence of persistent proteinuria. Stratified analysis of the two most significant risk factors (fasting blood glucose and age) indicated that hyperglycemia was a stronger risk factor for proteinuria in younger diabetic subjects, perhaps because of a competing risk of death in the elderly diabetic patient. In contrast to a recently described decreasing secular trend of proteinuria in Danish insulin-dependent diabetes mellitus patients, there was no decrease over the past 40 yr in proteinuria risk in this NIDDM incidence cohort.

The incidence and prevalence of diabetes mellitus in residents of Rochester, Minnesota, for 25 years (1945 to 1970) were determined from available medical records. The over-all incidence rate for diabetes is 133 new cases per 100,000 population per year (age-adjusted to 1970 U.S. white population). The rate increased with age for both men and women and was higher among men over 30 years of age. The average annual incidence rates per five-year period for juvenile-onset diabetes mellitus were low and variable and showed little change. Polyuria, polydipsia, glycosuria, lean habitus, loss of weight, and high levels of fasting hyperglycemia at initial diagnosis occurred more frequently in younger than in older patients. The peak incidence in 1960 through 1964 and the decrease in the following five years may be a reflection of the introduction of the AutoAnalyzer method for blood glucose in 1958. The average annual incidence rates for 1955 through 1959 and 1965 through 1969 were essentially the same. The over-all prevalence for diabetes mellitus is 1.6 per cent, with a higher rate among men than among women over 40 years of age; among school children the rate is 0.1 per cent. Survivorship in the diabetic population is lower than that in the general population. The leading cause of death was coronary heart disease, the death rate from it being higher than for the general population.

OBJECTIVEThe Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial demonstrated similar long-term clinical effectiveness of insulin-sensitizing (IS) versus insulin-providing (IP) treatments for type 2 diabetes on cardiovascular outcomes in a cohort with documented coronary artery disease. We evaluated the effects of randomized glycemic control strategy (IS vs. IP) on the prevalence and incidence of diabetic peripheral neuropathy (DPN).RESEARCH DESIGN AND METHODSDPN (defined as Michigan Neuropathy Screening Instrument [MNSI] clinical examination score >2) was assessed at baseline and yearly for 4 years. DPN prevalence and incidence were compared by intention-to-treat modeling by logistic generalized estimating equation models for prevalence and Kaplan-Meier estimates and Cox regression models for incidence rates.RESULTSResults are reported for 2,159 BARI 2D participants (70% males) with valid baseline and at least one follow-up MNSI score (mean age 62 ± 9 years, mean HbA1c 7.7 ± 1.6%, diabetes duration 10 ± 9 years). There were no differences in the prevalence of DPN between the IS and the IP groups throughout the 4 years of follow-up. In 1,075 BARI 2D participants with no DPN at baseline, the 4-year cumulative incidence rate of DPN was significantly lower in the IS (66%) than in the IP (72%) strategy group (P = 0.02), which remained significant after adjusting for the in-trial HbA1c (P = 0.04). In subgroup analyses, IS strategy had a greater benefit in men (hazard ratio 0.75 [99% CI 0.58–0.99], P < 0.01).CONCLUSIONSAmong patients with type 2 diabetes followed for up to 4 years during BARI 2D, a glycemic control therapy with IS significantly reduced the incidence of DPN compared with IP therapy and may add further benefit for men.

Abstract Maintaining results of successful induction therapy is an important goal in multiple myeloma. Here, members of the International Myeloma Working Group review the relevant data. Thalidomide maintenance therapy after autologous stem cell transplantation improved the quality of response and increased progression-free survival (PFS) significantly in all 6 studies and overall survival (OS) in 3 of them. In elderly patients, 2 trials showed a significant prolongation of PFS, but no improvement in OS. A meta-analysis revealed a significant risk reduction for PFS/event-free survival and death. The role of thalidomide maintenance after melphalan, prednisone, and thalidomide is not well established. Two trials with lenalidomide maintenance treatment after autologous stem cell transplantation and one study after conventional melphalan, prednisone, and lenalidomide induction therapy showed a significant risk reduction for PFS and an increase in OS in one of the transplant trials. Maintenance therapy with single-agent bortezomib or in combination with thalidomide or prednisone has been studied. One trial revealed a significantly increased OS with a bortezomib-based induction and bortezomib maintenance therapy compared with conventional induction and thalidomide maintenance treatment. Maintenance treatment can be associated with significant side effects, and none of the drugs evaluated is approved for maintenance therapy. Treatment decisions for individual patients must balance potential benefits and risks carefully, as a widely agreed-on standard is not established.

AbstractThe role of high-dose therapy followed by autologous stem cell transplantation (ASCT) in the treatment of multiple myeloma (MM) continues to evolve in the novel agent era. The choice of induction therapy has moved from conventional chemotherapy to newer regimens incorporating the immunomodulatory derivatives thalidomide or lenalidomide and the proteasome inhibitor bortezomib. These drugs combine well with traditional therapies and with one another to form various doublet, triplet, and quadruplet regimens. Up-front use of these induction treatments, in particular 3-drug combinations, has affected unprecedented rates of complete response that rival those previously seen with conventional chemotherapy and subsequent ASCT. Autotransplantation applied after novel-agent-based induction regimens provides further improvement in the depth of response, a gain that translates into extended progression-free survival and, potentially, overall survival. High activity shown by immunomodulatory derivatives and bortezomib before ASCT has recently led to their use as consolidation and maintenance therapies after autotransplantation. Novel agents and ASCT are complementary treatment strategies for MM. This article reviews the current literature and provides important perspectives and guidance on the major issues surrounding the optimal current management of younger, transplantation-eligible MM patients.
