Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a recent outbreak of coronavirus disease (COVID-19). In Cuba, the first case of COVID-19 was reported on March 11, 2020. Elderly individuals with multiple comorbidities are particularly susceptible to adverse clinical outcomes in the course of SARS-CoV-2 infection. During the outbreak, a local transmission event took place in a nursing home in Villa Clara province, Cuba, in which 19 elderly residents tested positive for SARS-CoV-2. METHODS Based on the increased susceptibility to cytokine release syndrome, inducing respiratory and systemic complications in this population, 19 patients were included in an expanded access clinical trial to receive itolizumab, an anti-CD6 monoclonal antibody. RESULTS All patients had underlying medical conditions. The product was well tolerated. After the first dose, the course of the disease was favorable, and 18 of the 19 patients (94.7%) were discharged clinically recovered with negative real-time reverse transcription polymerase chain reaction test results at 13 days. After one dose of itolizumab, circulating IL-6 decreased within the first 24-48 h in patients with high baseline values, whereas in patients with low levels, this concentration remained over low values. To preliminarily assess the effect of itolizumab, a control group was selected among the Cuban COVID-19 patients that did not receive immunomodulatory therapy. The control subjects were well matched regarding age, comorbidities, and severity of the disease. The percentage of itolizumab-treated, moderately ill patients who needed to be admitted to the intensive care unit was only one-third of that of the control group not treated with itolizumab. Additionally, treatment with itolizumab reduced the risk of death 10 times as compared with the control group. CONCLUSION This study corroborates that the timely use of itolizumab in combination with other antivirals reduces COVID-19 disease worsening and mortality. The humanized antibody itolizumab emerges as a therapeutic alternative for patients with COVID-19. Our results suggest the possible use of itolizumab in patients with cytokine release syndrome from other pathologies.

Discontinuation of disease-modifying treatments in multiple sclerosis to plan a pregnancy: A retrospective registry study. Mult Scler Relat Disord 2020; 46:102518. [PMID: 32977075 DOI: 10.1016/j.msard.2020.102518] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 08/13/2020] [Accepted: 09/15/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND For safety reasons multiple sclerosis (MS) treatment guidelines recommend stopping or delaying the onset of disease-modifying therapies (DMT) before a planned pregnancy, but disease stability after DMT discontinuation is not well studied. The objective of this study is to describe the course of MS in patients who interrupted DMT before a planned pregnancy. METHODS This was a retrospective study using 2008-2016 data from a multicenter register of pregnancies in women with MS. In this paper, we present data from the subgroup of women with relapsing-remitting MS (RRMS) who interrupted DMT to try to conceive. Data from 1 and 3 years before DMT interruption, the period between DMT interruption and conception or resuming DMT, during pregnancy and one year postpartum were analyzed. Annualized relapse rates (ARR), Expanded Disability Status Scale (EDSS) scores, and magnetic resonance imaging (MRI), obstetric, and neonatal data were collected. RESULTS Twenty-seven women interrupted DMT (19 β-interferon, 5 glatiramer acetate, 2 natalizumab and 1 fingolimod) to try to conceive. After a mean of 10.6 months 6 women stopped trying to conceive and resumed DMT, while 21 women became pregnant after a mean of 7.0 months. In the overall cohort, in the period from when DMT was discontinued to when pregnancy was confirmed or DMT resumed, the ARR was 1.08, which was significantly higher than the ARR 1 year (0.44; p = 0.01) and 3 years (0.4; p = 0.06) before DMT discontinuation. The mean EDSS score when pregnancy was confirmed or DMT resumed was significantly higher than at DMT discontinuation (1.8 vs 1.36, p = 0.011). In the subgroup of patients who became pregnant, the ARR in the untreated period before pregnancy was 0.98, which was significantly higher than the ARR 1 year (0.38; p = 0.03) and 3 years (0.39; p = 0.0077) before DMT discontinuation. The ARR decreased to 0.51 during pregnancy and then increased to 0.76 during the first postpartum trimester (not significant). One year after delivery, the mean EDSS score (1.86) was significantly higher than at DMT cessation (1.35, p = 0.027) or pregnancy confirmation (1.45, p = 0.026). Patients who suffered relapses following DMT cessation before becoming pregnant had an 11-fold higher risk of relapse during pregnancy (relative risk [RR] = 11.1 [95%CI 1.6, 75], p = 0.002) and a 3-fold higher risk during the postpartum year (RR = 3.0 [95%CI 1.3,6.6], p = 0.007) than those who did not suffer relapses in period between DMT withdrawal and pregnancy. CONCLUSIONS In this retrospective registry study, discontinuation of DMT (mostly immunomodulatory drugs), to try to conceive resulted in an increase in MS relapse rates and disability progression.

Abstract
Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS) where immunopathology is thought to be mediated by myelin-reactive CD4+ T helper (TH) cells. The TH cells most commonly implicated in the pathogenesis of the disease are of TH1 and TH17 lineage, which are defined by the production of interferon-γ and interleukin-17, respectively. Moreover, there is emerging evidence for the involvement of TH17.1 cells, which share the hallmarks of TH1 and TH17 subsets. In this review, we summarise current knowledge about the potential role of TH17 subsets in the initiation and progression of the disease and put a focus on their response to approved immunomodulatory MS drugs. In this regard, TH17 cells are abundant in peripheral blood, cerebrospinal fluid and brain lesions of MS patients, and their counts and inflammatory mediators are further increased during relapses. Fingolimod and alemtuzumab induce a paramount decrease in central memory T cells, which harbour the majority of peripheral TH17 cells, while the efficacy of natalizumab, dimethyl fumarate and importantly hematopoietic stem cell therapy correlates with TH17.1 cell inhibition. Interestingly, also CD20 antibodies target highly inflammatory TH cells and hamper TH17 differentiation by IL-6 reductions. Moreover, recovery rates of TH cells best correlate with long-term efficacy after therapeutical immunodepletion. We conclude that central memory TH17.1 cells play a pivotal role in MS pathogenesis and they represent a major target of MS therapeutics.

Abstract
Thalidomide, lenalidomide and pomalidomide are immunomodulatory drugs (IMiDs) effective in the treatment of multiple myeloma, myelodysplastic syndrome (MDS) with deletion of chromosome 5q and other hematological malignancies. Recent studies showed that IMiDs bind to CRBN, a substrate receptor of CRL4 E3 ligase, to induce the ubiquitination and degradation of IKZF1 and IKZF3 in multiple myeloma cells, contributing to their anti-myeloma activity. Similarly, lenalidomide exerts therapeutic efficacy via inducing ubiquitination and degradation of CK1α in MDS with deletion of chromosome 5q. Recently, novel thalidomide analogs have been designed for better clinical efficacy, including CC-122, CC-220 and CC-885. Moreover, a number of neo-substrates of IMiDs have been discovered. Proteolysis-targeting chimeras (PROTACs) as a class of bi-functional molecules are increasingly used as a strategy to target otherwise intractable cellular protein. PROTACs appear to have broad implications for novel therapeutics. In this review, we summarized new generation of immunomodulatory compounds, their potential neo-substrates, and new strategies for the design of novel PROTAC drugs.

Abstract
Objectives To describe the demographics and evaluate the clinical outcomes of hypoxic coronavirus disease-2019 (COVID-19) patients treated with different immunomodulatory (IM) drugs in a resource-limited setting. Materials and methods We conducted a retrospective cohort study of these patients admitted to our hospital between March 22 and May 31, 2020. Data were abstracted from multiple electronic data sources or patient charts to provide information on patient characteristics, clinical, laboratory variables, and outcomes. Results A total of 134 patients met the inclusion criteria and were followed up till June 7, 2020. The median age of the patients was 55.6 years (range 20–89 years) and 68% were men. At least one comorbidity was seen in 72% of the patients with diabetes (44%) and hypertension (46%) being the most common. At triage, fever (82%), shortness of breath (77%), and cough (61%) were the most common presenting symptoms. A PaO2/FiO2 ratio less than 300 was seen in 60%, and 4.5% required invasive mechanical ventilation within 72 hours of hospital admission. Five immunomodulatory agents (hydroxychloroquine, methylprednisolone, colchicine, etoricoxib, and tocilizumab) were administered in different combinations. Overall, in-hospital mortality was 26.9%, and 32% required mechanical ventilation. Around 69% of patients were discharged home. Five variables (SpO2, PaO2/FiO2 ratio, leucocytosis, lymphopenia, and creatinine) on admission were found to be significant in the patients who died. Conclusion Our study provides the characteristics and outcomes of hypoxic COVID-19 patients treated with IM drugs in varied combination. Five independent variables were strong predictors of mortality. How to cite this article Mahale N, Rajhans P, Godavarthy P, Narasimhan VL, Oak G, Marreddy S, et al.

Abstract
Langerhans cell histiocytosis (LCH) is a rare neoplastic disease in dendritic cells. LCH is classified as either a single-system (SS) or multisystem (MS) disease. There is not a standard first-line treatment for LCH in adults. We analyzed the efficacy and safety of immunomodulatory drugs (IMiDs) by searching PubMed/MEDLINE for case reports previously published. The clinical response (nonactive disease or active disease that regressed) was 94% in SS and 53% in MS. IMiDs should only be considered for adults with cutaneous SS involvement; in MS, they should be used only for patients not eligible for more aggressive treatments.

Abstract
This manuscript reviews the primary and secondary endpoints of pivotal phase III trials with immunomodulatory drugs in multiple sclerosis (MS). Considering the limitations of previous trial designs, we propose new standards for the planning of clinical trials, taking into account latest insights into MS pathophysiology and patient-relevant aspects. Using a systematic overview of published phase III (pivotal) trials performed as part of application for drug market approval, we evaluate the following characteristics: trial duration, number of trial participants, comparators, and endpoints (primary, secondary, magnetic resonance imaging outcome, and patient-reported outcomes). From a patient perspective, the primary and secondary endpoints of clinical trials are only partially relevant. High-quality trial data pertaining to efficacy and safety that stretch beyond the time frame of pivotal trials are almost non-existent. Understanding of long-term benefits and risks of disease-modifying MS therapy is largely lacking. Concrete proposals for the trial designs of relapsing (remitting) multiple sclerosis/clinically isolated syndrome, primary progressive multiple sclerosis, and secondary progressive multiple sclerosis (e.g., study duration, mechanism of action, and choice of endpoints) are presented based on the results of the systematic overview. Given the increasing number of available immunotherapies, the therapeutic strategy in MS has shifted from a mere “relapse-prevention” approach to a personalized provision of medical care as to the choice of the appropriate drugs and their sequential application over the course of the disease. This personalized provision takes patient preferences as well as disease-related factors into consideration such as objective clinical and radiographic findings but also very burdensome symptoms such as fatigue, depression, and cognitive impairment. Future trial designs in MS will have to assign higher relevance to these patient-reported outcomes and will also have to implement surrogate measures that can serve as predictive markers for individual treatment response to new and investigational immunotherapies. This is an indispensable prerequisite to maximize the benefit of individual patients when participating in clinical trials. Moreover, such appropriate trial designs and suitable enrolment criteria that correspond to the mode of action of the study drug will facilitate targeted prevention of adverse events, thus mitigating risks for individual study participants.

Abstract
Although there have been significant advances in the treatment of visceral leishmaniasis (VL) and several novel compounds are currently in pre-clinical and clinical development for this manifestation of leishmaniasis, there have been limited advances in drug research and development (R & D) for cutaneous leishmaniasis (CL). Here we review the need for new treatments for CL, describe in vitro and in vivo assays, models and approaches taken over the past decade to establish a pathway for the discovery, and pre-clinical development of new drugs for CL. These recent advances include novel mouse models of infection using bioluminescent Leishmania, the introduction of PK/PD approaches to skin infection, and defined pre-clinical candidate profiles.

Abstract
PURPOSE Immunomodulatory drugs (IMIDS) have changed the treatment and outcome of patients suffering from multiple myeloma. However, with the oral administration adherence becomes an issue. Since there is no "gold standard" in measuring adherence, we assessed the adherence of myeloma patients with the help of different data sources. METHODS All patients who have been receiving IMIDS for at least 3 months were eligible. Computer assisted personal interviews of patients and, if possible, their caregivers were carried out. Attending oncologists evaluated the patient's adherence with the help of a standardized questionnaire. In addition, a retrospective analysis of prescription data was conducted. All data were analyzed statistically using SPSS. RESULTS One hundred myeloma patients, 35% female, 65% male, with a median age of 70 years (37-86) were interviewed. Prescription data could be evaluated in terms of adherence in 78 patients (78%), 56 caregivers could be questioned (56%). Ninety-seven percent of patients rated themselves as adherent in taking IMIDS. Data from treating oncologists, caregivers and prescriptions supported this result. IMID therapies were rated as very effective and significant, toxicities were acceptable and dosing regimens simple/uncomplicated. CONCLUSIONS Myeloma patients seem to be highly adherent to IMID treatments.

Abstract
The introduction of proteasome inhibitors (PIs), such as bortezomib (BTZ), and immunomodulatory drugs (IMiDs), including thalidomide (THAL) and lenalidomide (LEN), as first-line therapies in multiple myeloma (MM) has markedly improved the clinical outcomes of patients. However, MM remains incurable, and most patients eventually relapse. Moreover, prognosis is poor in patients who exhibit resistance to BTZ or LEN, and novel therapeutic approaches for such patients are urgently needed. Currently, the following six drugs are available for use in relapsed patients: second generation PIs (carfilzomib and ixazomib), an IMiD (pomalidomide), a histone deacetylase (HDAC) inhibitor (panobinostat), and two monoclonal antibodies (elotuzumab and daratumumab). The choice of treatment should be individualized based on certain factors, such as age, presence of comorbidities, frailty, cytogenetic risk, efficacy and toxicity of prior treatments, and the duration of the previous response. A course of triplet therapy containing two novel agents along with DEX is recommended, on first relapse, in fit and healthy patients, whereas doublet therapy is preferred for unfit or frail patients. Retreatment of relapsed/refractory MM (RRMM) with monoclonal antibodies and IMiDs is promising because these drugs have immunostimulatory effects. In addition, novel agents, including an anti-BCMA antibody-drug conjugate, are being studied. Clinical trials are needed to define the optimal treatment strategy for RRMM.

Abstract
Cancer patients have an increased risk of thrombosis. The development of cancer thrombosis is dependent on a number of factors including cancer type, stage, various biologic markers, and the use of central venous catheters. In addition, cancer treatment itself may increase thrombotic risk. Tamoxifen increases the risk of venous thromboembolism (VTE) by two- to sevenfold, while an impact on risk of arterial thrombosis is uncertain. Immunomodulatory imide drugs (IMiDs) such as thalidomide and lenalidomide increase the risk of VTE in patients with multiple myeloma (MM) by about 10-40% when given in combination with glucocorticoids or other chemotherapy agents; the risk of VTE in MM patients treated with IMiD-containing regimens necessitates that such patients receive thromboprophylaxis with aspirin, low-molecular-weight heparin, or warfarin. Among cytotoxic chemotherapy agents, cisplatin, and to a lesser extent fluorouracil, has been described in association with thrombosis. L-asparaginase in treatment of acute lymphoblastic leukemia is significantly associated with increased thrombosis particularly affecting the CNS, which may be due to acquired antithrombin deficiency; at some centers, plasma infusions or antithrombin replacement is used to mitigate this. Bevacizumab, an inhibitor of vascular endothelial growth factor, increases arterial and possibly venous thrombotic risk, although the literature is conflicting about the latter. Supportive care agents in cancer care, such as erythropoiesis-stimulating agents, granulocyte colony stimulating factor, and steroids, also have some impact on thrombosis. This review summarizes the mechanisms by which these and other therapies modulate thrombotic risks and how such risks may be managed.

Abstract
PURPOSE OF REVIEW The purpose of this review was to evaluate management strategies for common adverse effects of novel therapies in multiple myeloma (MM), including immunomodulatory drugs, proteasome inhibitors, monoclonal antibodies, and a histone deacetylase inhibitor. RECENT FINDINGS There are several adverse effects that occur across multiple classes of antimyeloma drugs, including rash, peripheral neuropathy, infusion reactions, and cardiotoxicity, but most can be managed without complete discontinuation of the agent or abandonment of the class. Additionally, several agents have critically important drug-drug interactions or dose-modification implications in hepatic or renal insufficiency that can be easily overlooked, and exacerbate adverse effects. As treatment of MM moves from fixed-duration traditional chemotherapy to novel agent-based regimens, commonly administered continuously until disease progression or intolerable toxicities, providers must adopt their management strategies for both acute and long-term adverse effects. Early and frequent monitoring for therapy-related complications, dose adjustments when needed, and timely treatment for toxicities are all important steps toward ensuring longevity of treatment from a limited array of therapeutic options that currently exist for a disease with a relapsing and remitting course.

Abstract
This study identified 8-azaguanine (8-AG) as a novel immunomodulatory drug (IMiD) through a high-throughput screen of the Preswick Chemical Library in a model of human NK cell cytotoxicity against blood cancer cells. 8-AG, originally developed as an antineoplastic agent, significantly increased the cytotoxicity of NK cells and was superior in this activity to previously known IMiDs, such as fluoxetine and amphotericin B, identified from the same library. IFN-γ expression was also slightly increased by 8-AG. Mechanistically, 8-AG increased conjugate formation between NK and target cells and subsequent cytolytic granule polarization, but not calcium mobilization, regulation of activating receptors, or expression of perforin or granzyme B. Thus, the antineoplastic activity of 8-AG should be re-evaluated in light of this novel potentiating effect on NK cells.

Abstract
Introduction Uveal melanoma is a rare tumour caused by genetic factors and alterations in the immune response. Inflammatory bowel disease (IBD) is a multifactorial chronic inflammatory disorder characterized by an inappropriate or excessive immune response. The two main types of IBD are Crohn's disease (CD) and ulcerative colitis (UC). A diagnosis of IBD and the use of immunosuppressive drugs are both independently associated with an increased risk of developing skin melanoma. The association between IBD and uveal melanoma (UM) has not been previously described. Cases description Two young Caucasian men, aged 24 and 28, developed UM 3 and 15 years, respectively, after being diagnosed with IBD. Both received long-term treatment with immunomodulatory drugs, with periodic switching among the drugs due to the refractory nature of IBD. In both cases, melanoma was treated by brachytherapy with iodine-125 COMS plaque implant at a dose of 75 Gy. Discussion Chronic inflammation can promote cell proliferation and growth. The use of immunomodulatory drugs is associated with an increased risk of developing melanoma and non-melanoma skin cancer. The two patients described in this report both had long-standing IBD treated with immunomodulatory drugs. It seems reasonable to suggest that these two factors may have promoted the development of uveal melanoma. More studies are warranted to investigate and confirm this possible association.

Abstract
Multiple myeloma (MM) involves the immune dysregulation not only of B cells but also of NK, T, and dendritic cells. Furthermore, the number of regulatory T and myeloid-derived immunosuppressive cells, which are associated with disease progression, also increases. Immunomodulatory drugs (IMiDs) such as lenalidomide and pomalidomide exhibit an antimyeloma effect and improve the immune status. Thus, IMiD-enhanced antibody-dependent cell cytotoxicity increases the cytotoxic activity of monoclonal antibody treatment. Among many antibodies, anti-SLAMF7 elotuzumab and anti-CD38 daratumumab have been approved in Japan, and their targeted antigens are responsible for functions that may influence clinical efficacy. Daratumumab exerts various mechanisms of antitumor activity and enhances T-cell immunity by inhibiting immunosuppressive cells. New monoclonal antibodies, including the anti-CD38 antibody isatuximab and anti-BCMA antibody-drug conjugate, are being developed and are expected to demonstrate clinical efficacy. To improve long-term prognosis and achieve cure for MM, immunotherapies such as IMiD-intensified antibody treatment, which resulted in better response rates and longer survival in refractory/relapsed MM, are essential.

Abstract
The serpin family of serine proteinase inhibitors plays key roles in the maintenance of mammalian homeostasis. Virus-encoded serpins disrupt the balance of mammalian proteases to facilitate virus replication in the infected host. DNA viruses, in particular members of the poxvirus family, have acquired multiple copies of the functional serpins which are essential for viral pathogenesis. Virus-encoded serpins have proven to be very effective inhibitors of host proteases and thus are very attractive candidate molecules as immunomodulatory drugs. With this chapter we explain approaches to identifying immune-modulating viral serpins.

Abstract
Candidemia and other forms of invasive fungal infections caused by Candida glabrata and to a lesser extent Saccharomyces cerevisiae are a serious health problem, especially if their steadily rising resistance to the limited range of antifungal drugs is taken into consideration. Various drug combinations are an attractive solution to the resistance problem, and some drug combinations are already common in the clinical environment due to the nature of diseases or therapies. We tested a few of the common antifungal-immunomodulatory drug combinations and evaluated their effect on selected strains of C. glabrata and S. cerevisiae. The combinations were performed using the checkerboard microdilution assay and interpreted using the Loewe additivity model and a model based on the Bliss independence criterion. A synergistic interaction was confirmed between calcineurin inhibitors (Fk506 and cyclosporine A) and antifungals (fluconazole, itraconazole, and amphotericin B). A new antagonistic interaction between mycophenolic acid (MPA) and azole antifungals was discovered in non-resistant strains. A possible mechanism that explains this is induction of the Cdr1 efflux pump by MPA in C. glabrata ATCC 2001. The Pdr1 regulatory cascade plays a role in overall resistance to fluconazole, but it is not essential for the antagonistic interaction. This was confirmed by the Cgpdr1Δ mutant still displaying the antagonistic interaction between the drugs, although at lower concentrations of fluconazole. This antagonism calls into question the use of simultaneous therapy with MPA and azoles in the clinical environment.

Abstract
BACKGROUND Multiple myeloma (MM) is a hematological cancer caused by a proliferation of clonal plasma cells, leading to anemia, renal failure, hypercalcemia and destructive bone lesions resulting in significant morbidity. The overall survival has significantly improved with the incorporation of immunomodulatory drugs (IMiDs) and proteasome inhibitors (PI). OBJECTIVE Here we provide a comprehensive review on IMiDs including molecular mechanisms, recent advances in therapeutic applications and management of toxicities in the treatment of MM. METHODS Relevant publications in peer reviewed journals were retrieved by a selective search of PubMed. Systemic reviews, meta-analyses, randomized controlled trials, and treatment recommendations were reviewed and are summarized here. RESULTS Thalidomide, a first generation IMiD, is associated with significant toxicity in older patients. Lenalidomide, a more potent second generation IMiD with fewer side effects than thalidomide, is commonly used in newly-diagnosed multiple myeloma, relapsed refractory myeloma and as maintenance therapy after autologous stem cell transplantation (ASCT). Pomalidomide, a third generation IMiD, is 10 times more potent than lenalidomide and has shown impressive results in relapsed MM patients and in those refractory to both lenalidomide and bortezomib. CONCLUSION The clinical use of IMiDs in MM has significantly improved long-term survival and quality of life. Future studies are looking into novel biomarkers predictive of outcome in MM and new combinations of lenalidomide and pomalidomde with PI, monoclonal antibodies, immune checkpoint blockers and several other chemotherapies.

Abstract
BACKGROUND Coagulase-negative staphylococci (CoNS) such as Staphylococcus epidermidis are highly prevalent pathogens for sepsis in neonates. The interaction between host, environment and pathogenic factors of S. epidermidis are still poorly understood. Our objective was to address the role of several pathogenic factors of S. epidermidis on neonatal cytokine responses and to characterize the influence of three immunomodulatory drugs. METHODS We performed an ex-vivo model of S. epidermidis sepsis by assessment of blood cytokine production in neonatal whole blood stimulation assays (ELISA). S. epidermidis strains with different characteristics were added as full pathogen to umbilical cord blood cultures and the influence of indomethacin, ibuprofen and furosemide on neonatal immune response to S. epidermidis was evaluated (Flow cytometry). RESULTS Stimulation with S. epidermidis sepsis strains induced higher IL-6 and IL-10 expression than stimulation with colonization strains. Biofilm formation in clinical isolates was associated with increased IL-10 but not IL-6 levels. In contrast, stimulation with mutant strains for biofilm formation and extracellular virulence factors had no major effect on cytokine expression. Notably, addition of ibuprofen or indomethacin to S. epidermidis inoculated whole blood resulted in mildly increased expression of TNF-α but not IL-6, while frusemide decreased the production of pro-inflammatory cytokines, i.e. IL-6 and IL-8. CONCLUSIONS The virulence of sepsis strains is coherent with increased cytokine production in our whole-blood in-vitro sepsis model. Biofilm formation and expression of extracellular virulence factors had no major influence on readouts in our setting. It is important to acknowledge that several drugs used in neonatal care have immunomodulatory potential.

Abstract
This study aims to examine the risks of adverse events associated with anti-multiple myeloma (MM) therapies in a large population-based cohort of elderly patients with MM. Patients diagnosed with advanced MM from 2005 through 2009 and receiving anti-MM therapy were identified from the Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked data. We compared safety outcomes between novel agents (proteasome inhibitor (PI) and immunomodulatory drugs (IMiD)) and other therapies and between PI- or IMiD-based regimens and PI plus IMiD combination regimens. Of 2587 patients with advanced MM, 2048 (79%) received novel agents and 539 (21%) received other therapies. Patients with preexisting anemia and thrombocytopenia were significantly more likely to receive novel agents (85.9 vs. 82.4%, P = 0.038; 13.8 vs. 10.4%, P = 0.036), while those with preexisting cardiovascular disease and hypertension were significantly less likely to receive novel agents (73.4 vs. 79.8%, P = 0.003; 81.3 vs. 85.2%, P = 0.035). The hazard ratios for anemia, peripheral neuropathy, and thromboembolic events for patients receiving novel agents compared with those receiving other therapies were 1.19 (95% CI, 1.06-1.32), 1.57 (95% CI, 1.15-2.15), and 1.31 (95% CI, 1.03-1.67). The hazard ratios for anemia, neutropenia, and thromboembolic events for patients receiving PI plus IMiD combination therapies compared with those receiving PI- or IMiD-based therapies were 1.31 (95% CI, 1.12-1.54), 1.66 (95% CI, 1.27-2.18, and 1.37 (95% CI, 1.02-1.86). Novel agents significantly increased the risk of anemia, peripheral neuropathy, and thromboembolic events. PI plus IMiD combination therapies were associated with significantly higher risk for anemia, neutropenia, and thromboembolic events.

Abstract
The advent of novel agents for multiple myeloma (MM) is cause for a re-examination of the incidence of second primary malignancies (SPMs). We examined the SPM rate in MM patients who were enrolled in the prospective observational CALM (Collaboration to Collect Autologous Transplant outcome in Lymphoma and Myeloma) study. Between 2008 and 2012, 3204 patients with MM underwent a first autologous hematopoietic stem cell transplantation. Plerixafor was used as a mobilizing agent for patients with poor (or potentially poor) stem cell mobilization as defined by the respective centers. A total of 135 patients developed SPMs, with a cumulative incidence of 5.3% (95% confidence interval, 4.4 to 6.3) at 72 months. Ninety-four patients developed solid tumors, 30 developed hematologic malignancies, and 11 developed an SPM of an unknown type. The cumulative incidence of known hematologic and solid malignancies were 1.4% and 3.6%, respectively, at 72 months. In a univariate analysis, use of radiotherapy, type of induction regimen, hematopoietic stem cell dose, poor mobilizer status, plerixafor use, and sex did not influence the cumulative incidence of SPMs. Only age over 65 years was statistically associated with an increased incidence. Overall, the incidence of SPMs was comparable to earlier estimations of SPMs in MM.

Abstract
Community-acquired pneumonia (CAP) is the leading cause of death from infection in developed countries. There is evidence of an association between improved survival from infection and statin use. The possible beneficial effects of statins are complicated by the common use of macrolide antibiotics for pneumonia, with current guidance suggesting that concurrent macrolide and statin use is contraindicated.We conducted an observational study of statin use in patients with CAP. Of 2,067 patients with CAP, 30.4% were on statin therapy at admission. Statin users were more likely to survive the admission (p<0.001). In addition, we conducted a survey of doctors and found that knowledge regarding concurrent macrolide and statin use was lacking.These data suggest a potential role of statins in the management of CAP. Further research using high-dose statins is required to assess their safe use in subjects with mild to moderate infections.
