Abstract
About 30% of the FDA approved drugs in 2021 were protein-based therapeutics. However, therapeutic proteins can be unstable and rapidly eliminated from the blood, compared to conventional drugs. Furthermore, on-target but off-tumor protein binding can lead to off-tumor toxicity, lowering the maximum tolerated dose. Thus, for effective treatment therapeutic proteins often require continuous or frequent administration. To improve protein stability, delivery and release, proteins can be encapsulated inside drug delivery systems. These drug delivery systems protect the protein from degradation during (targeted) transport, prevent premature release and allow for long-term, sustained release. However, thus far achieving high protein loading in drug delivery systems remains challenging. Here, the use of protein desolvation with acetonitrile as an intermediate step to concentrate monoclonal antibodies for use in drug delivery systems is reported. Specifically, trastuzumab, daratumumab and atezolizumab were desolvated with high yield (∼90%) into protein nanoparticles below 100 nm with a low polydispersity index (<0.2). Their size could be controlled by the addition of low concentrations of sodium chloride between 0.5 and 2 mM. Protein particles could be redissolved in aqueous solutions and redissolved antibodies retained their binding activity as evaluated in cell binding assays and exemplified for trastuzumab in an ELISA.

Abstract
Objectives The purpose of this systematic review is to disclose the impact of autoimmune diseases and their medical treatment on dental implant survival and success. Material and Methods A literature search was conducted using MEDLINE (PubMed), The Cochrane Library and Embase up to December 6th, 2021. Any clinical study on patients with an autoimmune disease in whom implant therapy was performed was eligible. The quality of included studies was assessed using the Newcastle-Ottawa Scale. For each autoimmune disease group, data synthesis was divided into three groups: 1) overall results of the autoimmune disease, 2) overall results of corresponding control groups and 3) overall results of the autoimmune disease with a concomitant autoimmune disease (a subgroup of group 1). Descriptive statistics were used. Results Of 4,865 identified articles, 67 could be included and mainly comprising case reports and retrospective studies with an overall low quality. Implant survival rate was 50 to 100% on patient and implant level after a weighted mean follow-up of 17.7 to 68.1 months. Implant success was sporadically reported. Data on immunosuppressive medication were too heterogeneously reported to allow detailed analysis. Conclusions Overall, a high implant survival rate was reported in patients with autoimmune diseases. However, the identified studies were characterized by a low quality. No conclusions could be made regarding implant success and the effect of immunosuppressants due to heterogeneous reporting.

Abstract
OBJECTIVE Incidence of ulcerative colitis is globally increased. Enteric infections and their role in ulcerative colitis flares present a common health problem and a unique clinical challenge. We aimed to identify enteropathogens in flared ulcerative colitis patients and their antimicrobial susceptibilities and relation with the disease activity. METHODS Stool samples were collected from 95 patients with ulcerative colitis (17 inactive cases and 78 active cases) according to the Mayo score assessment of ulcerative colitis severity. Enteropathogens were examined using an automated VITEK2 system and FilmArray gastrointestinal pathogen panel. RESULTS Enteric infections were found in 81 patients (85.3%) with a significantly higher percentage in active ulcerative colitis (96.2% vs. 35.3%, P < 0.001). In 78 symptomatic patients, (78.7%) of bacteria as enteroaggregative and enteropathogenic E. coli , (11.5%) parasitic as Cryptosporidium and (7.7%) viral as Norovirus were the most detected microbial pathogens. Mixed, multidrug-resistant organisms (MDROs) and opportunistic infections were reported in 70.7%, 52.9% and 46.7% respectively. Raoultella ornithinolytica was reported for the first time as an enteropathogen in ulcerative colitis flare. Multiple organisms, MDROs, extended-spectrum beta-lactamases-producing and AmpC-resistant bacteria were significantly associated with disease severity. CONCLUSION Identifying enteropathogens especially opportunistic and MDR organisms as a cause of ulcerative colitis flare-ups is a matter of worry increasing their diagnostic and therapeutic burden. Periodic studies evaluating changes in microbial profiles and their antimicrobial susceptibilities are needed to achieve antibiotic stewardship and improve management.

Abstract
Biologics are becoming an increasingly important part of patient care across Canada. Recent studies from the USA show that Black patients are less likely than White patients to receive biologic treatment for several medical conditions. The relative lack of race-based data in Canada makes it difficult to replicate such studies in Canada. As a result, there is a paucity of literature that explores the association between biologic usage and race in Canada. Our review aims to explore the factors that might be driving racial treatment disparity in Canada that likely parallels the inequalities found in the USA. We provide a summary of the available literature on the factors that contribute to biologic treatment hesitancy among Black and Indigenous populations in Canada. We highlight several solutions that have been proposed in the literature to address biologic treatment hesitancy. Our review found that biologic treatment decision at the individual level can be very complex as patient's decisions are influenced by social inputs from family and trusted community members, biologic-related factors (negative injection experience, fear of needles, formulation, and unfamiliarity), cultural tenets (beliefs, values, perception of illness), and historical and systemic factors (past research injustices, socioeconomic status, patient-physician relationship, clinical trial representation). Some proposed solutions to address biologic treatment hesitancy among Black and Indigenous populations include increasing the number of Black and Indigenous researchers involved in and leading clinical trials, formally training physicians and healthcare workers to deliver culturally competent care, and eliminating financial barriers to accessing medications. Further research is needed to characterize and address race-based new treatment inequalities and hesitancy in Canada.

Abstract
OBJECTIVE Immunomodulatory therapies improve the management of chronic diseases but can be associated with infectious risk. The present study was undertaken to examine the laboratory screening practices for hepatitis B virus (HBV), hepatitis C virus (HCV), and tuberculosis (TB) and rates of vaccination for pneumococcal and influenza in patients prescribed select immunosuppressive agents at our institution. METHODS A retrospective analysis was conducted to review patients who were prescribed a select immunosuppressive over 3 years. Data were extracted from electronic health records to identify rates of screening and vaccination prior to initiation or at any time. Logistic regression models were developed to identify predictors of screening and vaccination. RESULTS We identified 2,396 patients prescribed immunosuppressive medications by rheumatology (52.6%) and non-rheumatology specialties. Rates of screening at any time point were 84.5% (2,025 of 2,396) for HBV, 76.7% (1,838 of 2,396) for HCV, and 71.8% (1,720 of 2,396) for TB. Patients who had either in-system primary care providers (PCPs) or rheumatologists were more likely to receive pneumococcal vaccinations (odds ratio [OR] 1.98 [95% confidence interval (95% CI) 1.55-2.54] and OR 4.08 [95% CI 2.76-6.02], respectively). Patients with dermatologic (OR 1.67 [95% CI 1.14-2.45]) or rheumatologic providers (OR 2.5 [95% CI 1.86-3.36]) were more likely to be vaccinated for influenza. CONCLUSION More than 70% of patients were screened for either HBV, HCV, or TB at some point. Rates of pneumococcal vaccination were better than rates of influenza vaccination. Patients with in-system PCPs were more likely to be screened and vaccinated. Establishing and executing consistent processes for screening and vaccination prior to immunosuppressive treatment remains a priority in ambulatory settings.

Abstract
Type 2 immunity evolved to combat helminth infections by orchestrating a combined protective response of innate and adaptive immune cells and promotion of parasitic worm destruction or expulsion, wound repair, and barrier function. Aberrant type 2 immune responses are associated with allergic conditions characterized by chronic tissue inflammation, including atopic dermatitis (AD) and asthma. Signature cytokines of type 2 immunity include interleukin (IL)-4, IL-5, IL-9, IL-13, and IL-31, mainly secreted from immune cells, as well as IL-25, IL-33, and thymic stromal lymphopoietin, mainly secreted from tissue cells, particularly epithelial cells. IL-4 and IL-13 are key players mediating the prototypical type 2 response; IL-4 initiates and promotes differentiation and proliferation of naïve T-helper (Th) cells toward a Th2 cell phenotype, whereas IL-13 has a pleiotropic effect on type 2 inflammation, including, together with IL-4, decreased barrier function. Both cytokines are implicated in B-cell isotype class switching to generate immunoglobulin E, tissue fibrosis, and pruritus. IL-5, a key regulator of eosinophils, is responsible for eosinophil growth, differentiation, survival, and mobilization. In AD, IL-4, IL-13, and IL-31 are associated with sensory nerve sensitization and itch, leading to scratching that further exacerbates inflammation and barrier dysfunction. Various strategies have emerged to suppress type 2 inflammation, including biologics targeting cytokines or their receptors, and Janus kinase inhibitors that block intracellular cytokine signaling pathways. Here we review type 2 inflammation, its role in inflammatory diseases, and current and future therapies targeting type 2 pathways, with a focus on AD.

Abstract
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a curative treatment for high-risk hematologic disorders. There are multiple immune-mediated complications following allo-HSCT that are prevented and/or treated by immunosuppressive agents. Principal among these immune-mediated complications is acute graft-versus-host disease (aGVHD), which occurs when the new donor immune system targets host tissue antigens. The immunobiology of aGVHD is complex and involves all aspects of the immune system. Due to the risk of aGVHD, immunosuppressive aGVHD prophylaxis is required for nearly all allogeneic HSCT recipients. Despite prophylaxis, aGVHD remains a major cause of nonrelapse mortality. Here, we discuss the clinical features of aGVHD, the immunobiology of aGVHD, the immunosuppressive therapies used to prevent and treat aGVHD, how to mitigate the side effects of these immunosuppressive therapies, and what additional immune-mediated post-allo-HSCT complications are also treated with immunosuppression.

Abstract
Biologic medications are an expanding field of therapeutics for various medical conditions including cancer and inflammatory diseases. Due to their targeted approach to therapy, biologics can be less toxic than traditional systemic medications. However, as use becomes more widespread, adverse effects from biologic administration have also become apparent. Immune-related adverse events are a common mechanism by which biologics can cause on-target immune-related toxicities and both immediate and delayed-type hypersensitivity reactions. Immediate hypersensitivity reactions can be mediated by cytokine release or antibody mediated reactions, while delayed-type hypersensitivity is most often caused by serum sickness-like reactions. Additionally, biologics used for treatment of cancer using checkpoint blockade and rheumatologic disease using cytokine blockade can result in autoimmunity. Finally, when inflammatory cytokines are targeted for treatment of autoimmune or autoinflammatory disease, the host immune defense can be compromised predisposing to secondary immunodeficiency. This review will discuss the mechanisms of these reactions and discuss examples of biologics implicated in each of these adverse events.

Abstract
The differential diagnosis for an acute Crohn's flare should include enteric infection, a challenging yet critical distinction to make when determining appropriate therapy. Since both present similarly, identification of an enteric infection should be performed with comprehensive stool microbial testing. In the setting of moderate-to-severe disease, patients on biologic therapy may be more prone to infectious complications. We present a patient with chronic Crohn's disease with an unusual, previously undetected enteric infection due to Plesiomonas shigelloides. Once identified, appropriate antibiotic treatment led to resolution of the patient's acute symptomatology. This is the first reported case of P. shigelloides infection in Crohn's disease.

Abstract
Selective suppression of graft rejection while maintaining anti-pathogen responses has been elusive. Thus far, the most successful strategies to induce suppression of graft rejection relies on inhibition of T-cell activation. However, the very same mechanisms that induce allograft-specific T-cell suppression are also important for immunity against microbial pathogens as well as oncogenically transformed cells, resulting in significant immunosuppression-associated comorbidities. Therefore, defining the pathways that differentially regulate anti-graft versus antimicrobial T-cell responses may allow the development of regimen to induce allograft-specific tolerance. Recent work has defined a molecular pathway driven by the immunoregulatory protein coronin 1 that regulates the phosphodiesterase/cyclic adenosine monophosphate pathway and modulates T cell responses. Interestingly, disruption of coronin 1 promotes allograft tolerance while immunity towards a range of pathogenic microbes is maintained. Here, we briefly review the work leading up to these findings as well as their possible implications for transplantation medicine.

Abstract
Polymeric nanoparticles that combine dexamethasone and naproxen reduce inflammation and synergistically inhibit Interleukin-12b (Il12b) transcription in macrophages. This effect can be the result of a cyclooxygenase-dependent or a cyclooxygenase-independent mechanism. The aim of this work is to obtain potent anti-inflammatory polymeric nanoparticles by the combination of dexamethasone and ketoprofen, one of the most efficient cyclooxygenase-inhibitors among non-steroidal anti-inflammatory drugs, with appropriate hydrodynamic properties to facilitate accumulation and co-release of drugs in inflamed tissue. Nanoparticles are spherical with hydrodynamic diameter (117 ± 1 nm), polydispersity (0.139 ± 0.004), and surface charge (+30 ± 1 mV), which confer them with high stability and facilitate both macrophage uptake and internalization pathways to favor their retention at the inflamed areas and lysosomal degradation and drug release, respectively. In vitro biological studies concluded that the dexamethasone-loaded ketoprofen-bearing system is non-cytotoxic and efficiently reduces lipopolysaccharide-induced nitric oxide release. The RT-qPCR analysis shows that the ketoprofen nanoparticles were able to reduce to almost basal levels the expression of tested pro-inflammatory markers and increase the gene expression of anti-inflammatory cytokines under inflammatory conditions. However, the synergistic inhibition of Il12b observed in nanoparticles that combine dexamethasone and naproxen was not observed in nanoparticles that combine dexamethasone and ketoprofen, suggesting that the synergistic trans-repression of Il12b observed in the first case was not mediated by cyclooxygenase-dependent pathways.

Abstract
The introduction of biologic and targeted immunomodulators is a significant breakthrough in the therapeutic area of various fields of medicine. The occurrence of serious infections, a complication of secondary immunosuppression associated with these agents, leads to increased morbidity and mortality. Implementing preventive strategies could minimize infection-related complications and improve therapeutic outcomes. The purpose of this review is to focus on current evident approaches regarding screening, monitoring, preventing (immunization and chemoprophylaxis), and management of infections in patients who are candidates for about 70 biologic and targeted immunomodulators. Recommendations are based on relevant guidelines, especially the ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document series published in 2018.

Abstract
Metastasis of cancer to the skeleton represents a debilitating turning point in the lives of patients. Skeletal metastasis leads to moderate to severe ongoing pain along with bone remodeling that can result in fracture, events that dramatically diminish quality of life. Interleukin-6 (IL-6) levels are elevated in patients with metastatic breast cancer and are associated with a lower survival rate. We therefore determined the consequences of inhibition of IL-6 signaling using a novel small molecule antagonist, TB-2-081, on bone integrity, tumor progression, and pain in a rodent model of breast cancer. Rat MAT B III mammary adenocarcinoma cells were injected and sealed within the tibia of female Fischer rats. Growth of these cells within the rat tibia elicited increased IL-6 levels both within the bone exudate and in the plasma, produced ongoing pain and evoked hypersensitivity, and bone fracture that was observed by approximately day 12. Systemic TB-2-081 delivered by subcutaneous osmotic minipumps starting at tumor implantation prevented tumor-induced ongoing bone pain and evoked hypersensitivity without altering tumor growth. Remarkably, TB-2-081 infusion significantly reduced osteolytic and osteoblastic bone remodeling and time to fracture likely by decreasing osteoclastogenesis and associated increase in bone resorption. These findings indicate that blockade of IL-6 signaling may represent a viable, disease-modifying strategy to prevent tumor-induced bone remodeling allowing for stabilization of bone and decreased fractures as well as diminished ongoing pain that may improve quality of life of patients with skeletal metastases. Notably, anti-IL-6 antibodies are clinically available allowing for rapid testing of these possibilities in humans.
