Abstract
Monoclonal gammopathy of undetermined significance (MGUS) precedes multiple myeloma (MM). Population-based screening for MGUS could identify candidates for early treatment in MM. Here we describe the Iceland Screens, Treats, or Prevents Multiple Myeloma study (iStopMM), the first population-based screening study for MGUS including a randomized trial of follow-up strategies. Icelandic residents born before 1976 were offered participation. Blood samples are collected alongside blood sampling in the Icelandic healthcare system. Participants with MGUS are randomized to three study arms. Arm 1 is not contacted, arm 2 follows current guidelines, and arm 3 follows a more intensive strategy. Participants who progress are offered early treatment. Samples are collected longitudinally from arms 2 and 3 for the study biobank. All participants repeatedly answer questionnaires on various exposures and outcomes including quality of life and psychiatric health. National registries on health are cross-linked to all participants. Of the 148,704 individuals in the target population, 80 759 (54.3%) provided informed consent for participation. With a very high participation rate, the data from the iStopMM study will answer important questions on MGUS, including potentials harms and benefits of screening. The study can lead to a paradigm shift in MM therapy towards screening and early therapy.

Abstract
Monoclonal gammopathies are associated with advancing age but a familial predisposition has been recognized for several decades. A functional phenotype, characterized by increased immunoglobulin (Ig) production after mitogen stimulation has been identified in healthy members of 4 families showing a predisposition toward IgM and IgG/IgA disorders. B cells from these hyperresponders do not show increased rates of Ig gene translocations and no aberrations were detected in an in vitro model of the germinal center reaction. Array-based comparative genome hybridization revealed deletions of Ig genes in peripheral blood B cells, as expected. In addition, random changes were detected throughout the genome, presumably reflecting off-target activation-induced cytidine deaminase (AID) activity. These random changes were significantly less prevalent in B cells from hyperresponders, indicating less exposure to the germinal center environment during maturation.

Abstract
The prevalence of paraproteinemias or monoclonal gammopathies increases with age. No other major risk factors have been recognized, but significant associations have been reported with chronic antigen exposure, agricultural environment, and family history. In around 130 families reported worldwide, IgG or IgA monoclonal gammopathy of undetermined significance (MGUS) occurs with multiple myeloma (MM) whereas Waldenström's macroglobulinemia (WM) is linked to IgM MGUS. Of the 8 multi-case families described here, 5 are remarkable for including both IgG/IgA and IgM type disorders. In the remaining 3 families IgG/IgA MGUS and MM occurred with Hodgkin disease and T-cell malignancies. These different patterns of familial paraproteinemia indicate different genetic backgrounds. A previously described functional phenotype of hyper-responsive B lymphocytes fulfils criteria for being an endophenotype and may be related to raised serum IgM. Identifying an endophenotype is important to ensure correct classification of affected family members and thus enhance the power of genetic studies.

Abstract
BACKGROUND In Iceland, eight families have been identified with multiple cases of monoclonal gammopathies (MG) and other lymphoproliferative diseases. In one of these families with several cases of monoclonal gammopathy of undetermined significance (MGUS) and Waldenströms macroglobulinemia, in vitro stimulation with poke-weed mitogen revealed hyper-responsive B cells showing increased immunoglobulin production in one-third of disease-free family members. DESIGN AND METHODS In this study, the families were further traced and the list of names produced was compared with The Icelandic Cancer Registry (ICR) to find all recent cases of lymphoproliferative diseases. First-degree relatives and descendants older than 20yrs of age (n=350) were selected for screening for paraprotein. Selected family members were tested for B-cell hyper-responsiveness and the lymphocyte phenotype was analysed by flow cytometry. RESULTS Comparison of the total list of 4370 family members with the ICR revealed 22 new cases and screening for serum paraprotein identified nine new cases of MG, eight being first-degree relatives of known probands. Sixty cases of lymphoproliferative diseases are currently known within the eight families, five of them containing both IgG/A and IgM disorders. Twelve hyper-responders (HR) were identified in four families, eight from one family, of whom four were known already. Stimulated B cells from HR had a significantly higher proportion of CD27(+) memory/plasma cells than controls. CONCLUSION Identification of new affected family members by screening confirms a hereditary predisposition to B-cell proliferative diseases. Contrary to most studies, IgG/A and IgM disorders occurred together in five families. In four families, enhanced B-cell responsiveness was found in healthy subjects clustered around cases.

Abstract
A 46-year-old previously healthy woman was diagnosed with acute lymphoblastic leukaemia. The induction phase was complicated by alpha-haemolytic streptococcal bacteremia which responded to antibacterial therapy. Subsequently, the patient developed pneumonie due to Chlamydiapneumoniae which responded to macrolides. Following this infection the patient developed recurrent fever and new pulmonary infiltrates were noted. Bronchoscopy was performed and treatment was administered with liposomal amphotericin B (L-AmB, AmBisome) for two days, but was complicated by acute renal failure. Aspergillus fumigatus was cultured from bronchoalveolar lavage fluid [corrected] L-AmB was discontinued and voriconazole and caspofungin were administered. Despite aggressive antifungal therapy the patient developed progressive invasive infection, with central nervous system involvement as well as lesions appearing in the kidneys and liver. The patient died one week following the diagnosis of aspergillosis.
