Psoriatic dactylitis: from immunopathogenesis to anti-cytokine and targeted synthetic therapies.

OBJECTIVES: Psoriatic arthritis (PsA) is an immune-inflammatory disease occurring in a subgroup of patients suffering from psoriasis. Dactylitis is recognised as a hallmark of PsA, being present in about 50% of patients. This article gives an overview of the complexity of psoriatic dactylitis, looking at clinical aspects as well as pathogenetic aspects and subsequent insights into treatment strategies. METHODS: The review focuses on the main evidence on pathogenesis, clinical features, and management of psoriatic dactylitis. RESULTS: In recent years, more studies have focused their attention on dactylitis in PsA patients, leading to a greater understanding of its pathogenesis and clinical presentation and to a growing expansion of the therapeutic armamentarium. Dactylitis is frequently associated with more severe PsA phenotype, often representing the initial feature of the disease. Its prompt recognition can be key for addressing early diagnosis and therapy of PsA, thus leading to better clinical and radiographic outcomes. CONCLUSIONS: There has been considerable progress in understanding psoriatic dactylitis, but major challenges remain. Although there has been a recent expansion in the therapeutic armamentarium for psoriatic dactylitis, there is still a paucity of evidence on a precision approach to this manifestation.

The role of bDMARDs in the prevention and treatment of inflammatory-related comorbidities in Psoriatic Arthritis.

INTRODUCTION: Psoriatic arthritis (PsA) is an immune-inflammatory disease that affects both joints and entheses, and with diverse extra-articular manifestations (psoriasis, inflammatory bowel disease (IBD), and uveitis). A wide range of comorbid conditions, including cardiovascular diseases, obesity, metabolic syndrome (MetS), nonalcoholic fatty liver disease (NAFLD), mental health disorders (depression/anxiety), and osteoporosis are highly prevalent in course of PsA.Biological DMARDs (bDMARD), including TNF-inhibitors (TNFi), Interleukin (IL-17i) and IL-23i represent the cornerstone of the management of active disease. The use of these therapies obviously requires considering comorbidities presence, safety aspects and contraindications. AREAS COVERED: The aim of this review is to describe the inflammatory mechanisms behind PsA comorbidities, and the role of bDMARDs in the prevention and treatment of these conditions in course of PsA. EXPERT OPINION: Tailoring therapeutic strategies to the individual characteristics of each PsA patient can be an effective approach to manage comorbidities, maximizing the efficacy of bDMARDs, and reducing the incidence of AEs. Identifying targets within disease pathways can guide research into therapeutics that address both PsA and comorbidities simultaneously, but more studies are advocated for clarifying the potential prevention and management of bDMARDs used for PsA.

Early psoriatic arthritis: clinical and therapeutic challenges.

INTRODUCTION: Psoriatic arthritis (PsA) is a chronic immunoinflammatory disease of the enthesis and adjacent synovium, skin, and nail, which early diagnosis may be crucial for starting a prompt therapeutic intervention. Theoretically, early treatment offers the advantage of acting on the reduction of the articular damage progression since initial phases of the disease. AREAS COVERED: This review explores the challenges of clinical-diagnostic aspects and the underlying pathophysiology of early PsA phases, as well as the evidence evaluating the impact of early intervention on disease outcomes. EXPERT OPINION: Main instruments for early PsA diagnosis include recognizing synovial-entheseal inflammatory signs at onset, improving screening PsA high-risk subjects, and increasing disease knowledge of physicians and patients with psoriasis or familial history. PsA continues to significantly impact on the Quality of Life of patients affected by the disease, making necessary to deeply study clinical manifestations, risk factors, and underlying immunoinflammatory mechanisms, as well as to identify biomarkers for early identification. Additionally, it remains a need to increase more evidence on understanding how early treatment of PsA and of psoriasis might influence the course of the disease.

A reverse translational approach reveals the protective roles of Mangifera indica in inflammatory bowel disease.

Inflammatory bowel diseases (IBDs) are chronic intestinal disorders often characterized by a dysregulation of T cells, specifically T helper (Th) 1, 17 and T regulatory (Treg) repertoire. Increasing evidence demonstrates that dietary polyphenols from Mangifera indica L. extract (MIE, commonly known as mango) mitigate intestinal inflammation and splenic Th17/Treg ratio. In this study, we aimed to dissect the immunomodulatory and anti-inflammatory properties of MIE using a reverse translational approach, by initially using blood from an adult IBD inception cohort and then investigating the mechanism of action in a preclinical model of T cell-driven colitis. Of clinical relevance, MIE modulates TNF-α and IL-17 levels in LPS spiked sera from IBD patients as an ex vivo model of intestinal barrier breakdown. Preclinically, therapeutic administration of MIE significantly reduced colitis severity, pathogenic T-cell intestinal infiltrate and intestinal pro-inflammatory mediators (IL-6, IL-17A, TNF-α, IL-2, IL-22). Moreover, MIE reversed colitis-induced gut permeability and restored tight junction functionality and intestinal metabolites. Mechanistic insights revealed MIE had direct effects on blood vascular endothelial cells, blocking TNF-α/IFN-γ-induced up-regulation of COX-2 and the DP2 receptors. Collectively, we demonstrate the therapeutic potential of MIE to reverse the immunological perturbance during the onset of colitis and dampen the systemic inflammatory response, paving the way for its clinical use as nutraceutical and/or functional food.

Loss of RAS Mutations in Liquid Biopsies of Patients With Multi-Treated Metastatic Colorectal Cancer.

BACKGROUND: Liquid biopsy (LB) is a non-invasive tool to evaluate the heterogeneity of tumors. Since RAS mutations (RAS-mut) play a major role in resistance to antiepidermal growth factor receptor inhibitors (EGFR) monoclonal antibodies (Mabs), serial monitoring of RAS-mut with LB may be useful to guide treatment. The main aim of this study was to evaluate the prognostic value of the loss of RAS-mut (NeoRAS-wt) in LB, during the treatment of metastatic colorectal cancer (mCRC). METHODS: A retrospective study was conducted on patients with mCRC between January 2018 and December 2021. RAS-mut were examined in tissue biopsy, at mCRC diagnosis, and with LB, during treatment. RESULTS: Thirty-nine patients with RAS-mut mCRC were studied. LB was performed after a median of 3 lines (0-7) of systemic treatment including anti-vascular endothelial growth factor (anti-VEGF) Mabs. NeoRAS-wt was detected in 13 patients (33.3%); 9 (69.2%) of them received further treatment with anti-EGFR Mabs with a disease control rate of 44.4%. Median overall survival (OS), from the date of LB testing, was 20 months in the NeoRAS-wt group and 9 months in the persistent RAS-mut group (log-rank 2.985; P = .08), with a 12-month OS of 84.6% and 57.7%, respectively. NeoRAS-wt was identified as a predictor of survival (HR = 0.29; P = .007), with an 11-month improvement in median OS and a 71% decrease in risk of death, in heavily pretreated patients. CONCLUSIONS: In conclusion, monitoring clonal evolution in mCRC by LB may provide an additional treatment line for patients with NeoRAS-wt in advanced disease.

JAK Inhibitors in Psoriatic Disease.

Psoriasis is now considered to be the cutaneous phenotype of a systemic inflammatory condition, recognized under the term Psoriatic Disease (PsD). PsD has several extracutaneous manifestations, such as inflammatory articular and entheseal involvement, leading to psoriatic arthritis (PsA), and the less frequent intestinal and ocular manifestations with colitis/inflammatory bowel disease and uveitis, respectively. There have also been several reports of an increased frequency of comorbidities such as hypertension, diabetes, dyslipidemia, obesity, metabolic syndrome and cardiovascular manifestations during the course of PsD. The link between psoriasis and related comorbidities is considered a long-term disease sequela, often characterized by an unhealthy lifestyle and a consequence of systemic inflammation; hence, psoriasis requires adequate and prompt treatment, with the aim of controlling not only cutaneous manifestations but also extracutaneous manifestations and systemic inflammation. Pharmacological strategies for PsD have significantly increased over recent years. Recently, the targeted synthetic DMARDs, Janus kinase (JAK) inhibitors, tofacitinib and upadacitinib, were added to the therapeutic armamentarium for treating PsA, and deucravacitinib for psoriasis. These oral agents act directly on inflammatory mechanisms underlining the disease, as antagonists of the intracellular JAK signal pathway and, by STAT phosphorylation, inhibit gene proinflammatory cytokine transcription. JAK inhibitors represent a recent additional treatment strategy for PsD management and, among these, tofacitinib and upadacitinib have recently been approved for PsA, and deucravacitinib for psoriasis. In this review we describe ongoing and recent phase II and III randomized controlled trials (RCTs) evaluating the efficacy and safety of investigational JAK inhibitors in psoriasis and PsA.

Role of Patrick-FABER test in detecting sacroiliitis and diagnosing spondyloarthritis in subjects with low back pain.

OBJECTIVES: To evaluate sensitivity, specificity, and predictive value of Patrick-FABER test in assessing magnetic resonance imaging (MRI) sacroiliitis and addressing the diagnosis of spondyloarthritis (SpA) in subjects with low back pain (LBP). METHODS: Subjects with LBP were consecutively enrolled. The assessors were blinded to patients' clinical, laboratory, or imaging data. All subjects underwent sacroiliac joint MRI to detect presence of sacroiliac oedema or structural changes. RESULTS: One hundred and ten subjects were included in the study [males (61.8%); median age of 45 (21-69) years; LBP duration of 78 (3-240) months]. Patrick-FABER test sign's sensitivity was 76.2% (95% CI: 60.5-87.9%), specificity was 66.2% (95% CI: 53.6-77.2%), positive predictive value (PPV) was 58.1% (95% CI: 44.1-71.3%) and negative predictive value (NPV) was 81.8% (95% CI: 69.1-90.9%) for the diagnosis of sacroiliitis, with an overall diagnostic accuracy of 70%. At the univariate and multivariate analysis, Patrick-FABER test sign was associated with inflammatory lesions of sacroiliitis at MRI and SpA diagnosis. Univariate and multivariate analysis showed an association between smoking status (p=0.01), sacroiliitis, and SpA diagnosis. The odds of having sacroiliitis was 2.7 higher in smokers (OR: 2.7; 95% CI: 1.1-7) as compared to non-smokers and 6.3 higher in those with a positive Patrick-FABER test sign (OR: 6.3; 95%CI: 2.5-15.6) as compared to those with a negative sign. CONCLUSIONS: Our study shows that Patrick-FABER test positivity could represent a useful clinical test for addressing the use of sacroiliac joints MRI and SpA diagnosis in subjects with LBP. Further, smoking habit could represent an associate anamnestic element for addressing the use of sacroiliac MRI.

The negative impact of pain catastrophising on disease activity: analyses of data derived from patient-reported outcomes in psoriatic arthritis and axial spondyloarthritis.

OBJECTIVES: Psychosocial factors are recognised as important determinants of pain experience in patients with inflammatory arthritides. Among them, pain catastrophising, a maladaptive cognitive style, observed in patients with anxiety and depressive disorders, garnered specific attention. Here, we evaluated pain catastrophising (PC) and its related domains (Rumination, Magnification, and Helplessness), in psoriatic arthritis (PsA) and axial spondyloarhtiritis (axSpA) participants, to assess its impact on disease activity. Furthermore, we analysed possible correlations of PC-Scale (PCS) with those psychometric domains which have been already related to catastrophisation in patients with chronic pain. Lastly, we aimed to define the relationship between PCS and the different variables included in the composite indices of disease activity. METHODS: A multi-centre, cross-sectional, observational study has been conducted on 135 PsA (age 56 (47-64) years, males/females 40.74/59.26%; Disease Activity in Psoriasic Arthritis (DAPSA) 13.34 (5.21-22.22)) and 71 axSpA (age 49 (37-58) years, males/females 56.34/43.66%; Bath Ankylosing Spondylitis Arthritis Activity (BASDAI) 4.17 (2.1-6.3)) participants. Multivariable regressions and correlations were performed to evaluate the relationship between pain catastrophising and both disease activity and patient-reported outcomes. RESULTS: The adjusted linear regression model showed a positive association between PCS and DAPSA as well as between PCS and BASDAI; PCS negative impacts on the subjective domains of disease activity scores. CONCLUSIONS: This study suggests the role of PC, independently of inflammation, in disease perception and achievement of remission or low disease activity in chronic arthritides.

Recent developments for new investigational JAK inhibitors in psoriatic arthritis.

INTRODUCTION: Psoriatic arthritis (PsA) is a chronic inflammatory disease affecting about one-third of subjects with psoriasis. Several treatment modalities targeting Janus Kinase pathways and intracellular inflammatory cascade are now available and under clinical investigation to treat this disease. AREAS COVERED: This review describes ongoing and recently completed phase 2 and 3 randomized clinical trials (RCTs) evaluating the efficacy and safety of approved JAK (Tofacitinib and Upadacitinib) and investigational JAK inhibitors (JAK1 inhibitors: Filgotinib and Ivarmacitinib (SHR0302); TYK2 inhibitors: Brepocitinib (PF-06700841) Deucravacitinib (BMS-986165), and NDI-034858) in PsA through February 2023. EXPERT OPINION: Current standard of care has significantly improved the quality of life in PsA. Recently approved JAK inhibitors for PsA have addressed many of the unmet needs of PsA, particularly of those with severe phenotypes. Preliminary results from several RCTs have reported good and fast efficacy and an acceptable safety profile of investigational JAK inhibitors in PsA. Additional clinical trials and long-term outcome data on these agents are necessary for increasing available therapeutic options for PsA.

Management of Psoriatic Arthritis in Patients With Comorbidities: An Updated Literature Review Informing the 2021 GRAPPA Treatment Recommendations.

OBJECTIVE: The 2021 Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) treatment recommendations provide an evidence-based guide for selecting therapy based on the individual's disease features. Beyond the disease features and associated conditions (eg, uveitis and inflammatory bowel disease), comorbidities play an important role in selecting therapy for an individual patient. METHODS: We performed a systematic literature review. We examined the available evidence to inform treatment selection based on the presence or absence of comorbidities in psoriatic arthritis (PsA). RESULTS: Common comorbidities in PsA that may affect treatment selection include presence of baseline cardiovascular disease (CVD) or high risk for CVD, obesity and metabolic syndrome, liver disease, mood disorders, including depression in particular, chronic infections, malignancies, osteoporosis, and fibromyalgia and/or central sensitization. CONCLUSION: Comorbidities may influence both the effectiveness of a given therapy but also the potential for adverse events. It is important to assess for the presence of comorbidities prior to therapy selection.

Association of Tumor-Infiltrating Lymphocytes With Survival in Stages II and III Colorectal Cancer.

The tumor microenvironment is crucial in tumourigenesis, response to therapy, and elimination of tumor cells. Tumor-infiltrating lymphocytes (TILs) promote the host immune response and are associated with a better prognosis in colorectal cancer (CRC). This multicentric retrospective study evaluated the relationship between the presence and intensity of TILs and survival outcomes. A total of 651 patients from four Portuguese oncological centers who underwent surgical resection for stages II or III colorectal adenocarcinoma between 2016 and 2019 were included in this study. The mean age of the study population was 70 years; 58.2% were males. The median overall survival was 58.03 ± 1.29 months (95% confidence interval (CI) 55.50 - 60.56), and the median disease-free survival (DFS) was 53.02 ± 1.39 months (95% CI 50.29 - 55.74). Patients with high infiltrate (including those with moderate, abundant, or Crohn-like infiltrate) had significantly longer DFS i.e., 58.48 ± 1.84 months (95% CI 54.87 - 62.09 months) vs 49.22 ± 1.75 months (95% CI 45.79 - 52.64 months) in the group with absent or minimal infiltrate; p = 0.003. Assessing the side of the tumor, high infiltrate was associated with higher DFS (59.86 ± 2.36 months (95% CI 55.23 - 64.50 months) vs 49.60 ± 2.40 months (95% CI 44.90 - 54.29 months), p = 0.011). This work reinforces the importance of research into possible prognostic and predictive factors in patients with CRC.

Neuroendocrine carcinoma of vagina with prolonged survival.

We report the case of a woman in her 70s with a stage IVA small cell neuroendocrine carcinoma of the vagina. The patient started chemotherapy with cisplatin and etoposide followed by concurrent chemoradiotherapy and adjuvant chemotherapy. Pelvic MRI after completion of treatment did not show residual disease. Three years and 8 months after definitive treatment, the patient remains on regular follow-up without evidence of disease.

Analysis of rheumatoid- vs psoriatic arthritis synovial fluid reveals differential macrophage (CCR2) and T helper subsets (STAT3/4 and FOXP3) activation.

OBJECTIVE: In psoriatic arthritis (PsA) and rheumatoid arthritis (RA), inflammatory responses are characterized by increased production of pro-inflammatory molecules secreted by various immune cells. The main objectives of our study were: i) to measure levels of pro- and anti-inflammatory cyto-chemokines and soluble factors expressed in both PsA and RA SF; ii) to characterize the phenotype of infiltrated leuko-lymphocytes and; iii) to identify specific synovial biomarkers for both diseases. Notably, Synovial Fluid (SF) samples obtained from PsA and RA populations were compared with SF samples collected from clinically active osteoarthritis (OA) joints. METHODS: SF samples were collected from clinically active knee arthritis of PsA, RA and OA patients and assayed for cyto-chemokines profile and macrophage and T helper subsets markers and transcriptional factors by Elisa Spot and western blot. RESULTS: our study revealed that modulation of CCL-2, G-CSF, IL-1ß and TNF-α is peculiar and specific to RA synovial fluid, whereas we detected more significant levels of ICAM-1, IL-2, IL-6, IL-17A, C5a and CXCL-9/12 in PsA compared to RA patients. We also found that CCR2 expression appeared to be significantly upmodulated in PsA and, even more, in RA group, as well as the expression of specific Th and Treg transcriptional factors as STAT3/4 and FOXP3. CONCLUSION: Even though this study has several limitations, we identified a heterogenous scenario of peculiar molecular pathway and soluble mediators' production that characterize PsA and RA SF that may be useful in understanding the complex pattern of macrophages and lymphocytes infiltration in both pathologies and, potentially, pave the way for personalized precision therapies.

Neutrophile-to-lymphocyte, lymphocyte-to-monocyte, and platelet-to-lymphocyte ratios as prognostic and response biomarkers for resectable locally advanced gastric cancer.

BACKGROUND: Perioperative fluorouracil plus leucovorin, oxaliplatin, and docetaxel (FLOT) improves prognosis in locally advanced gastric cancer (LAGC). Neutrophil-to-lymphocyte (NLR), lymphocyte-to-monocyte (LMR), and platelet-to-lymphocyte (PLR) ratios are prognostic biomarkers but not predictive factors. AIM: To assess blood ratios' (NLR, LMR and PLR) potential predictive response to FLOT and survival outcomes in resectable LAGC patients. METHODS: This was a multicentric retrospective study investigating the clinical potential of NLR, LMR, and PLR in resectable LAGC patients, treated with at least one preoperative FLOT cycle, from 12 Portuguese hospitals. Means were compared through non-parametric Mann-Whitney tests. Receiver operating characteristic curve analysis defined the cut-off values as: High PLR > 141 for progression and > 144 for mortality; high LMR > 3.56 for T stage regression (TSR). Poisson and Cox regression models the calculated relative risks/hazard ratios, using NLR, pathologic complete response, TSR, and tumor regression grade (TRG) as independent variables, and overall survival (OS) as the dependent variable. RESULTS: This study included 295 patients (mean age, 63.7 years; 59.7% males). NLR was correlated with survival time (r = 0.143, P = 0.014). PLR was associated with systemic progression during FLOT (P = 0.022) and mortality (P = 0.013), with high PLR patients having a 2.2-times higher risk of progression [95% confidence interval (CI): 0.89-5.26] and 1.5-times higher risk of mortality (95%CI: 0.92-2.55). LMR was associated with TSR, and high LMR patients had a 1.4-times higher risk of achieving TSR (95%CI: 1.01-1.99). OS benefit was found with TSR (P = 0.015) and partial/complete TRG (P < 0.001). Patients without TSR and with no evidence of pathological response had 2.1-times (95%CI: 1.14-3.96) and 2.8-times (95%CI: 1.6-5) higher risk of death. CONCLUSION: Higher NLR is correlated with longer survival time. High LMR patients have a higher risk of decreasing T stage, whereas high PLR patients have higher odds of progressing under FLOT and dying. Patients with TSR and a pathological response have better OS and lower risk of dying.

Lymph node yield in the pathological staging of resected nonmetastatic colon cancer: The more the better?

INTRODUCTION: Guidelines recommend regional lymphadenectomy with a lymph node yield (LNY) of at least 12 lymph nodes (LN) for adequate colon cancer (CC) staging. LNY ≥22LN may improve survival, especially in right-sided CC [Lee et al., Surg Oncol, 27(3), 2018]. This multicentric retrospective cohort study evaluated the impact of LNY and tumor laterality on CC staging and survival. MATERIALS AND METHODS: Patients with stage I-III CC that underwent surgery from 2012 to 2018 were grouped according to LNY: <22 and ≥ 22. Primary outcomes were LN positivity (N+ rate) and disease-free survival (DFS). Overall survival (OS) was the secondary outcome. Exploratory analyses were performed for laterality and stage. RESULTS: We included 795 patients (417 < 22LN, 378 ≥ 22LN); 53% had left-sided CC and 29%/37%/38% had stage I/II/III tumors. There was no association between LNY ≥22LN and N+ rate after adjustment for grade, T stage, lymphovascular invasion (LVI) and perineural invasion; a trend for a higher N+ rate in left-sided CC was identified (interaction p = 0.033). With a median follow-up of 63.6 months for DFS and 73.2 months for OS, 254 patients (31.9%) relapsed and 207 (26.0%) died. In multivariate analysis adjusted for age, ASA score, laparoscopic approach, T/N stage, mucinous histology, LVI and adjuvant chemotherapy, LNY ≥22LN was significantly associated with both DFS (HR 0.75, p = 0.031) and OS (HR 0.71, p = 0.025). Restricted cubic spline analysis showed a more significant benefit for right-sided CC. CONCLUSION: LNY ≥22LN was associated with longer DFS and OS in patients with operable CC, especially for right-sided CC.

Radio-cephalic fistula recovered with drainage to median basilic vein by straightening of the forearm cephalic vein: A case report.

The distal arteriovenous fistula (AVF) has less complications and better patency than the proximal fistula, when it works properly. The complications of outflow of the fistula are complex, and it is necessary to analyze all solutions to solve the problem. We introduce a novel approach to solve outflow problems of a radio-cephalic AVF by straightening of the forearm cephalic vein with drainage into the median basilic vein.

Long-term effectiveness and drug survival of golimumab in patients affected by psoriatic arthritis with cutaneous involvement.

OBJECTIVES: To determine the effectiveness of golimumab (GLM) in improving joint, periarticular structures and cutaneous manifestations in patients with moderate to severe psoriatic arthritis (PsA) with cutaneous psoriasis in different real-life clinical settings and 48-month drug survival. METHODS: Clinical and laboratory records were collected from PsA patients treated with GLM at baseline (T0) and after 6, 12, 24, 36, and 48 months of treatment. Comparisons were performed using a paired t-test or Wilcoxon test. Drug survival rates were analyzed using Kaplan-Meier estimates. p value < 0.05 was considered statistically significant. RESULTS: Data from 105 patients were collected. PsO occurred in 80% of patients and enthesitis in 78%, peripheral and axial arthritis in 63.8% and 35.3%, respectively, while erosions in 36.2%. The main comorbidities were cardiovascular diseases (31.4%) and metabolic syndrome (MetS) (19%). A statistically significant improvement in articular and cutaneous psoriasis was registered at T48 of GLM-therapy in clinical (DAPSA p < 0.0001; PASI p < 0.01; BASDAI p < 0.0001) and laboratory (CRP < 0.05) indexes. Gender (p = 0.652), BMI (p = 0.655), smoking habit (p = 0.466), and line of treatment (p = 0.208) did not affect treatment efficacy nor persistence. At T48, 42% of patients discontinued GLM: the most frequent reason was an insufficient response or loss of efficacy (28.6%). CONCLUSION: A 48-month GLM high drug persistence of PsA patients was observed in real-life, in patients presenting high disease activity, elevated prevalence of comorbidities, and more than one line of treatment at baseline. Patients' characteristics as gender, smoke, BMI, different lines of treatment, and concomitant methotrexate treatment affected treatment persistence, making GLM effective and safe in moderate-severe PsA in a long-term real-life setting. Key Points • Golimumab was effective in psoriatic arthritis, including both musculoskeletal and cutaneous manifestations. • Golimumab effectiveness and drug survival were not affected by comorbidities and patient-related characteristics. • The 4-year drug survival curves confirm the efficacy and safety of golimumab in psoriatic arthritis patients in a real-life setting.
