Osteopontin: A New Facilitating Factor in Alopecia Areata Pathogenesis?

Osteopontin (OPN) is a multifunctional glycophosphoprotein secreted by many cell types, including osteoblasts, lymphocites, macrophages, epithelial cells, and vascular smooth muscle cells. It has been implicated in many physiological and pathological processes, such as cell-mediated immunity, inflammation, cell survival, and tumor invasion and metastasis. Osteopontin has multiple emerging roles in cutaneous biology and pathology and OPN involvement has been emphasized in Th1-mediated diseases such as psoriasis. Alopecia areata (AA) is a form of non-scarring hair loss affecting anagen stage hair follicles with a multifactorial autoimmune pathogenesis characterized by a prevalent Th1 cytokine profile. Given the role of osteopontin in Th1-mediated inflammation, we have postulated that OPN may be involved in AA pathogenesis. The aim of our study was to investigate plasma OPN level in alopecia areata before and after DPCP treatment. Our results showed that OPN plasma levels in patients with alopecia areata were higher than in healthy controls, but patients achieving complete recovery after DPCP treatment did not show a statistically significant reduction of OPN plasma levels.</p

MSCs and inflammation: not only a guardian role

  The literature on the relation between mesenchymal stem cells (MSCs) and inflammation is continuing to expand at a rapid rate with over 600 entries in PubMed under “MSCs and inflammation” starting from 2002. Inflammation is an essential part of the malignant microenvironment. Chemokines, leukocyte infiltration and cytokines are crucial elements, which contribute to cancer-related inflammation. Attracted by chemokines, MSCs are recruited at injury sites. After exposure to inflammatory factors in the local microenvironment, MSCs secrete several cytokines and vascular endothelial growth factor, which promote immunosuppression, angiogenesis and tumor growth. Here we compare by RT-PCR the expression of selected genes, related to inflammation, on MSCs derived from control (C-MSCs) and inflamed tissues (I-MSCs). First of all, an immunohistochemistry using anti-CD43 antibody was performed to better test the status of inflammation at the moment of tissues’ collection. CD43 is known as marker of inflammation, since it is expressed by most T cells, activated B cells, basophils, macrophages, monocytes and NK cells. Its expression was absent in “control” tissues, while it was strong in the “inflamed”. Subsequently, RNA was extracted, retro-transcribed and used for quantitative PCR. The genes were selected according to their role in inflammation: IL6 and IL8 (known as pro-inflammatory interleukins), TNFα (involved in systemic inflammation), CXCL2 (secreted by monocytes and macrophages and is chemotactic for polymorphonuclear leukocytes), CCL20 (strongly chemotactic for lymphocytes, its expression is induced by inflammatory cytokines), IFNγ (an important activator of macrophages) and TGFβ1 (promoting immunosuppression). Quantification of mRNA expression was calculated with the 2−ΔΔCt method, where ΔCt = Ct (gene of interest) − Ct (control gene) and Δ(ΔCt) = ΔCt (I-MSCs) − ΔCt (C-MSCs). The results revealed that the expression of all tested genes was higher in MSCs derived from inflamed tissues than in MSCs from control tissues (expressed as 1). This study underlines how MSCs are not inert guardians on inflammation, but as they play an active role

Bortezomib Plus Dexamethasone Followed by Escalating Donor Lymphocyte Infusions for Patients with Multiple Myeloma Relapsing or Progressing after Allogeneic Stem Cell Transplantation

Abstract Multiple myeloma relapsing after allogeneic stem cell transplantation (alloSCT) has a poor outcome. To assess the safety and efficacy of bortezomib and dexamethasone (VD) combination followed by donor lymphocyte infusions (DLIs) in myeloma patients relapsing or progressing after alloSCT, a prospective phase II study was designed. The treatment plan consisted of three VD courses followed by escalated doses of DLIs in case of response or at least stable disease. Nineteen patients were enrolled with a median age of 57 years (range, 33 to 67); 14 patients were allografted from human leukocyte antigen–identical siblings and 5 from alternative donors. Sixteen of 19 patients received the planned treatment, but 3 patients did not: 2 patients because of disease progression and 1 refused. After the VD phase the response rate was 62%, with 1 complete remission, 6 very good partial remissions, 5 partial remissions, 2 patients with stable disease, and 5 with progressive disease. After the DLI phase, the response rate was 68%, but a significant upgrade of response was observed: 3 stringent complete remissions, 2 complete remissions, 5 very good partial remissions, 1 partial remission, 4 with stable disease, and 1 with progressive disease. With a median follow-up of 40 months (range, 29 to 68), the 3-year progression-free survival and overall survival rates were 31% and 73%, respectively. Neither unexpected organ toxicities, in particular severe neuropathy, nor severe acute graft-versus-host disease flares were observed. VD-DLIs is a safe treatment for multiple myeloma patients relapsing or progressing after alloSCT and may be effective

Patient satisfaction with calcipotriol/betamethasone dipropionate cutaneous foam for the treatment of plaque psoriasis: The LION real-life multicenter prospective observational cohort study

Topical treatment is the mainstay for mild or moderate psoriasis, but patients are generally little satisfied. Calcipotriol/betamethasone dipropionate (Cal/BD) cutaneous foam has shown to improve signs and symptoms in plaque psoriasis patients. This study assessed patient's satisfaction with Cal/BD foam in a real-life Italian dermatological clinical practice. A multicenter, 4-week observational prospective cohort study enrolled, in 17 Italian dermatology clinics, adult patients with plaque psoriasis on the body and/or scalp. Treatment satisfaction was assessed by 9-item Treatment Satisfaction Questionnaire for Medication (TSQM-9), preference over previous treatments by Patient Preference Questionnaire (PPQ), and change in disease state by Psoriasis Area Severity Index (PASI). Overall 256 patients were eligible, with a mean (SD) age of 55.6 (15.4) years, 59.4% were males. Psoriasis severity was mild in 52.0% of patients, moderate in 43.3%, and severe in 4.7%. Scalp involvement was present in 36.7% of patients. Previous antipsoriatic treatments had been received by 80.5% of patients. TSQM-9 median (25th-75th percentile) scores were 83.3 (66.7-88.9) for effectiveness, 77.8 (66.7-88.9) for convenience, and 78.6 (64.3-92.9) for global satisfaction. Mean (SD) PASI value decreased from 7.3 (4.8) to 2.1 (2.7) after 4 weeks. More than 90% of patients previously treated for psoriasis evaluated the Cal/BD foam more effective, easier to use and better tolerated compared to previous topical treatments at PPQ. This observational study provides real-life evidence of a high level of satisfaction with effectiveness and convenience of the Cal/BD foam in a cohort of plaque psoriasis patients, with an objective improvement in PASI

Multidisciplinary Management of Spondyloarthritis-Related Immune-Mediated Inflammatory Disease

Immune-mediated inflammatory diseases (IMIDs) are chronic autoimmune conditions that share common pathophysiologic mechanisms. The optimal management of patients with IMIDs remains challenging because the coexistence of different conditions requires the intervention of several specialists. The aim of this study was to develop a series of statements defining overarching principles that guide the implementation of a multidisciplinary approach for the management of spondyloarthritis (SpA)-related IMIDs including SpA, psoriasis, psoriatic arthritis, Crohn's disease, ulcerative colitis and uveitis

The role of ixazomib as an augmented conditioning therapy in salvage autologous stem cell transplant (ASCT) and as a post-ASCT consolidation and maintenance strategy in patients with relapsed multiple myeloma (ACCoRd [UK-MRA Myeloma XII] trial): study protocol for a Phase III randomised controlled trial

Background: Multiple myeloma (MM) is a plasma cell tumour with an approximate annual incidence of 4500 in the UK. Therapeutic options for patients with MM have changed in the last decade with the arrival of proteasome inhibitors and immunomodulatory drugs. Despite these options, almost all patients will relapse post first-line autologous stem cell transplantation (ASCT). First relapse management (second-line treatment) has evolved in recent years with an expanding portfolio of novel agents, driving response rates influencing the durability of response. A second ASCT, as part of relapsed disease management (salvage ASCT), has been shown to prolong the progression-free survival and overall survival following a proteasome inhibitor-containing re-induction regimen, in the Cancer Research UK-funded National Cancer Research Institute Myeloma X (Intensive) study. It is now recommended that salvage ASCT be considered for suitable patients by the International Myeloma Working Group and the National Institute for Health and Care Excellence NG35 guidance. Methods/design: ACCoRd (Myeloma XII) is a UK-nationwide, individually randomised, multi-centre, multiple randomisation, open-label phase III trial with an initial single intervention registration phase aimed at relapsing MM patients who have received ASCT in first-line treatment. We will register 406 participants into the trial to allow 284 and 248 participants to be randomised at the first and second randomisations, respectively. All participants will receive re-induction therapy until maximal response (four to six cycles of ixazomib, thalidomide and dexamethasone). Participants who achieve at least stable disease will be randomised (1:1) to receive either ASCTCon, using high-dose melphalan, or ASCTAug, using high-dose melphalan with ixazomib. All participants achieving or maintaining a minimal response or better, following salvage ASCT, will undergo a second randomisation (1:1) to consolidation and maintenance or observation. Participants randomised to consolidation and maintenance will receive consolidation with two cycles of ixazomib, thalidomide and dexamethasone, and maintenance with ixazomib until disease progression. Discussion: The question of how best to maximise the durability of response to salvage ASCT warrants clinical investigation. Given the expanding scope of oral therapeutic agents, patient engagement with long-term maintenance strategies is a real opportunity. This study will provide evidence to better define post-relapse treatment in MM

Long-Term Drug Survival and Effectiveness of Secukinumab in Patients with Moderate to Severe Chronic Plaque Psoriasis: 42-Month Results from the SUPREME 2.0 Study

Purpose: SUPREME, a phase IIIb study conducted in Italy, demonstrated safety and high efficacy of secukinumab for up to 72 weeks in patients with moderate-to-severe plaque-type psoriasis. SUPREME 2.0 study aimed to provide real-world data on the long-term drug survival and effectiveness of secukinumab beyond 72 weeks. Patients and Methods: SUPREME 2.0 is a retrospective observational chart review study conducted in patients previously enrolled in SUPREME study. After the end of the SUPREME study, eligible patients continued treatment as per clinical practice, and their effectiveness and drug survival data were retrieved from medical charts. Results: Of the 415 patients enrolled in the SUPREME study, 297 were included in SUPREME 2.0; of which, 210 (70.7%) continued secukinumab treatment throughout the 42-month observation period. Patients in the biologic-naïve cohort had higher drug survival than those in the biologic-experienced cohort (74.9% vs 61.7%), while HLA-Cw6–positive and HLA-Cw6–negative patients showed similar drug survival (69.3% and 71.9%). After 42 months, Psoriasis Area and Severity Index (PASI) 90 was achieved by 79.6% of patients overall; with a similar proportion of biologic-naïve and biologic-experienced patients achieving PASI90 (79.8% and 79.1%). The mean absolute PASI score reduced from 21.94 to 1.38 in the overall population, 21.90 to 1.24 in biologic-naïve and 22.03 to 1.77 in biologic-experienced patients after 42 months. The decrease in the absolute PASI score was comparable between HLACw6–positive and HLA–Cw6-negative patients. The baseline Dermatology Life Quality Index scores also decreased in the overall patients (10.5 to 2.32) and across all study sub-groups after 42 months. Safety was consistent with the known profile of secukinumab, with no new findings. Conclusion: In this real-world cohort study, secukinumab showed consistently high long-term drug survival and effectiveness with a favourable safety profile
