Symptomatic androgen deficiency and sexual dysfunctions in male patients receiving alectinib for ALK-positive advanced non-small cell lung cancer.

BACKGROUND: It is reported that treatment with anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKIs) induces hypogonadism both in male patients with ALK-positive cancer and in murine models. METHODS: In this study, three groups, including an experimental group of male patients with ALK-positive, advanced non-small cell lung cancer (ANSCLC) who were receiving alectinib (cohort A), a control group of female patients with ALK-positive ANSCLC who were receiving alectinib (cohort B), and a control group of male patients with ALK-negative ANSCLC (cohort C), prospectively underwent a full hormone assessment for androgen deficiency at 8 weeks after the start of treatment and in case of reported suspected symptoms. Patients with major sexual dysfunctions were referred to an endocrinologist. RESULTS: Ninety-five patients were consecutively enrolled onto the study. Among sixty-eight male patients, both median total testosterone levels (2.93 vs. 4.92 ng/ml; p = .0001) and free testosterone levels (0.11 vs. 0.17 pg/ml; p = .0002) were significantly lower in ALK-positive ANSCLC patients in cohort A compared with ALK-negative patients in cohort C; conversely, median FSH (10.32 vs. 17.52 mUI/ml; p = .0059) and LH levels (4.72 vs. 7.49 mUI/ml; p = .0131) were significantly higher in cohort C compared to cohort A. Median inhibin B levels were higher in ALK-positive male patients (74.3 vs. 44.24 pg/ml; p = .0038), but all patients had inhibin B values within the normal range. The percentage of male patients who had positive scores on the Androgen Deficiency in Aging Males (ADAM) questionnaire was 62% in cohort A and 26.8% in cohort C, including eight patients who reported at least one major symptom and were referred to Andrology Unit. No significant differences in the endocrine assessment were reported between cohorts A and B. CONCLUSIONS: Symptoms of androgen deficiency should be tracked in male patients with ALK-positive ANSCLC who are receiving alectinib, and testosterone replacement should be considered, as appropriate.

Diagnostic capabilities, clinical features, and longitudinal UBA1 clonal dynamics of a nationwide VEXAS cohort.

VEXAS is a prototypic hemato-inflammatory disease combining rheumatologic and hematologic disorders in a molecularly defined nosological entity. In this nationwide study, we aimed at screenshotting the current diagnostic capabilities and clinical-genomic features of VEXAS, and tracked UBA1 longitudinal clonal dynamics upon different therapeutics, including allogeneic hematopoietic cell transplant. We leveraged a collaboration between the Italian Society of Experimental Hematology and of Rheumatology and disseminated a national survey to collect clinical and molecular patient information. Overall, 13/29 centers performed UBA1 genomic testing locally, including Sanger sequencing (46%), next-generation sequencing (23%), droplet digital polymerase chain reaction (8%), or combination (23%). A total of 41 male patients were identified, majority (51%) with threonine substitutions at Met41 hotspot, followed by valine and leucine (27% and 8%). Median age at VEXAS diagnosis was 67 years. All patients displayed anemia (median hemoglobin 9.1 g/dL), with macrocytosis. Bone marrow vacuoles were observed in most cases (89%). The most common rheumatologic association was polychondritis (49%). A concomitant myelodysplastic neoplasm/syndrome (MDS) was diagnosed in 71% of patients (n = 28), chiefly exhibiting lower Revised International Prognostic Scoring System risk profiles. Karyotype was normal in all patients, except three MDS cases showing -Y, t(12;16)(q13;q24), and +8. The most frequently mutated gene was DNMT3A (n = 10), followed by TET2 (n = 3). At last follow-up, five patients died and two patients progressed to acute leukemia. Longitudinal UBA1 clonal dynamics demonstrated mutational clearance following transplant. We collected a nationwide interdisciplinary VEXAS patient cohort, characterized by heterogeneous rheumatologic manifestations and treatments used. MDS was diagnosed in 71% of cases. Patients exhibited various longitudinal UBA1 clonal dynamics.

Response to first-line pembrolizumab in metastatic KRAS-mutated non-small-cell lung cancer.

Aims: This retrospective study aims to identify a possible predictive role of KRAS mutations in non-small-cell lung cancer in response to first-line pembrolizumab, either as monotherapy or combined with chemotherapy. Methods: Patients received pembrolizumab alone (n = 213) or associated with chemotherapy (n = 81). Results: A mutation in the KRAS gene was detected in 27% of patients. In patients on pembrolizumab alone, median progression-free survival in KRAS-mutated cases was longer than in wild-type cases (11.3 vs 4.4 months; p = 0.019), whereas median overall survival did not reach statistical significance (22.1 vs 12.5 months; p = 0.119). Patients receiving chemo-immunotherapy with KRAS-positive tumors had a similar progression-free survival (9.7 vs 7.3 months; p = 0.435); overall survival data were immature. Conclusion: This study suggests a correlation between KRAS status and response to pembrolizumab.

Diagnostic role of minor salivary glands biopsy in Sjögren's syndrome: correlations between histology and autoimmunity in a large, monocentric cohort.

Introduction: Based on ACR/EULAR classification criteria, minor salivary glands biopsy (MSGB) is a useful diagnostic tool for the diagnosis of primary Sjögren's syndrome (SS). The main objective of our study was to evaluate the diagnostic role of MSGB, as well as to highlight correlations between histological findings and autoimmune profiles. Material and methods: We retrospectively evaluated histological and autoimmunity data from patients who underwent MSGB in our department in cases of suspected SS, from March 2011 to December 2018. Salivary gland samples were evaluated using Chisholm and Mason (CM) grading and the focus score (FS). Results: A total of 1,264 patients (108 males, 1,156 females) were included. The median age was 55.22 ±13.51 years (range: 15-87). In univariate binary logistic regression, CM ≥ 3 and FS ≥ 1 were significantly predicted by antinuclear antibodies (ANA), anti-extractable nuclear antigens (ENA) and anti-Ro/SSA titer as well as anti-La/SSB, anti-Ro/SSA, rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) positivity. In multivariate analysis, CM ≥ 3 and MSGB positivity were significantly associated with ANA titer; FS ≥ 1 was not associated with laboratory findings. A positive biopsy was associated with laboratory findings, as ANA and ENA titers, anti-Ro/SSA, anti-La/SSB, RF and ACPA positivity may discriminate patients with SS-related histological findings. Conclusions: Minor salivary glands biopsy is a useful tool to diagnose SS in cases of highly suggestive clinical symptoms but in the absence of a specific autoimmunity.

Disparities in the prevalence of clinical features between systemic juvenile idiopathic arthritis and adult-onset Still's disease.

OBJECTIVE: To compare clinical features and treatments of patients with systemic JIA (sIJA) and adult-onset Still's disease (AOSD). METHODS: The clinical charts of consecutive patients with sJIA by International League of Association of Rheumatology criteria or AOSD by Yamaguchi criteria were reviewed. Patients were seen at a large paediatric rheumatology referral centre or at 10 adult rheumatology academic centres. Data collected included clinical manifestations, inflammation biomarkers, systemic score, macrophage activation syndrome (MAS), parenchymal lung disease, disease course, disability, death and medications administered. RESULTS: A total of 166 patients (median age at diagnosis 5 years) with sJIA and 194 patients with AOSD (median age at diagnosis 41 years) were included. The frequency of fever, rash, arthralgia, abdominal pain, MAS, parenchymal lung disease and increased acute phase reactants and ferritin were comparable between the two cohorts. Patients with sJIA had a higher prevalence of arthritis, whereas patients with AOSD had experienced leucocytosis and extra-articular organ involvement more frequently. Patients with AOSD were given more commonly low-dose corticosteroids, whereas biologic DMARDs were administered first-line more frequently in patients with sJIA. CONCLUSION: We found remarkable disparities in the prevalence of clinical manifestations between the two illnesses, which may partly depend on their classification by different criteria.

Retention rate of IL-1 inhibitors in Schnitzler's syndrome.

OBJECTIVES: Schnitzler's syndrome is a rare autoinflammatory disease. Clinical response to IL-1 inhibitor drugs has been described, but limited information is available on the long-term efficacy and safety of these agents in Schnitzler's syndrome. METHODS: A retrospective study was conducted of patients with Schnitzler's syndrome fulfilling Strasbourg diagnostic criteria followed in 9 Italian centres. The retention rate of IL-1 inhibitors was evaluated using Kaplan-Meier analysis. RESULTS: Fifteen of 20 patients with Schnitzler's syndrome were treated with IL-1 inhibitors: in total, they received 16 courses of anakinra (median duration 20.0 months [6.0-58.3]), and 8 courses of canakinumab (median duration 19.0 months [13.5-31.0]). The retention rate of IL-1 inhibitors was 73.4% [SE 9.4] at 1 year and 63.6% [SE 10.4] at 2 years. There was no significant difference between the retention rate of anakinra and canakinumab. The retention rate was higher in patients with a definite diagnosis according to the Strasbourg criteria as compared with those with a probable diagnosis (p=0.03). At the last follow-up visit, all patients who started therapy with IL-1 inhibitors were still on treatment, although in some cases with an increased dosage compared to the start of therapy. A sparing effect on the use of conventional synthetic disease-modifying anti-rheumatic drugs and a significant reduction of prednisone dosage (p=0.02) and of serum amyloid A (SAA) levels (p=0.03) were observed. CONCLUSIONS: The retention rate of IL-1 inhibitors in patients with Schnitzler's syndrome was high, particularly in patients with a definite diagnosis according to the Strasbourg criteria, reflecting their effectiveness in the treatment of this syndrome.

Adult-onset Still's disease with elderly onset: results from a multicentre study.

OBJECTIVES: In this study, we aimed at describing the clinical characteristics, life-threatening complications occurrence, and mortality of adult-onset Still's disease (AOSD) patients with elderly onset. METHODS: A multicentre retrospective study of prospectively followed-up AOSD patients included in Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale (GIRRCS) cohort was performed. RESULTS: Out of 221 assessed patients, 37 (16.7%) had an onset of the disease aged over 60 years. When compared with younger patients, these were characterised by a higher prevalence of pericarditis (p=0.008), comorbidities (p<0.0001), and mortality (p=0.023). Age predicted the presence of serositis in both univariate (HR: 1.02, 95%CI: 1.01-1.03, p=0.007) and multivariate analyses (HR: 1.02, 95%CI: 1.01-1.04, p=0.007). Age was also a significant predictor of parenchymal lung disease in both univariate (HR: 1.03, 95%CI: 1.01-1.05, p=0.017) and multivariate analyses (HR: 1.03, 95%CI: 1.00-1.05, p=0.048). Furthermore, age resulted to be a negative predictor of polycyclic pattern only in univariate analysis (HR: 0.99, 95%CI: 0.97-1.00, p=0.048). Finally, age significantly predicted the mortality in both univariate (HR: 1.03, 95%CI: 1.00-1.06, p=0.034) and multivariate analyses (HR: 1.05, 95%CI: 1.01-1.08, p=0.012). CONCLUSIONS: Clinical features of AOSD patients in the elderly were described in our cohort. Although the main clinical characteristics were similar comparing older and younger patients, patients aged over 60 years at disease onset were characterised by an increased prevalence of serositis, comorbidities, mostly cardiometabolic, and a higher mortality rate. Age predicted the presence of parenchymal lung disease and mortality, and it could be considered a negative prognostic factor in AOSD.

Paraneoplastic arthritides: an up-to-date case-based systematic review.

Among the rheumatic diseases whose symptoms are more often associated with the possibility of cancer and other malignancies are systemic sclerosis, dermatomyositis and rheumatic polymyalgia. However, a differential diagnosis should be performed in each case of non-typical rheumatic disease and/or other neoplastic disease risk factors. The article's aim was based on a literature review of this subject and presentation own a case description and discussion about arthritis as a paraneoplastic syndrome. The conclusions of our analysis were as follows: more often paraneoplastic arthritis occurs in men, in ages higher than 50 years old, in patients who poorly respond to treatment of arthritis with polyarticular symmetrical involvement of the limbs, seronegative type of inflammatory joint disease. In this group of patients, complete remission after treatment of the primary tumor and recurrence of the symptoms in the presence of metastasis was observed.

Drug survival of anakinra and canakinumab in monogenic autoinflammatory diseases: observational study from the International AIDA Registry.

OBJECTIVES: To investigate survival of IL-1 inhibitors in monogenic autoinflammatory disorders (mAID) through drug retention rate (DRR) and identify potential predictive factors of drug survival from a real-life perspective. PATIENTS AND METHODS: Multicentre retrospective study analysing patients affected by the most common mAID treated with anakinra or canakinumab. Survival curves were analysed with the Kaplan-Meier method. Statistical analysis included a Cox-proportional hazard model to detect factors responsible for drug discontinuation. RESULTS: Seventy-eight patients for a total of 102 treatment regimens were enrolled. The mean treatment duration was 29.59 months. The estimated DRR of IL-1 inhibitors at 12, 24 and 48 months of follow-up was 75.8%, 69.7% and 51.1%, respectively. Patients experiencing an adverse event had a significantly lower DRR (P=0.019). In contrast, no significant differences were observed between biologic-naïve patients and those previously treated with biologic drugs (P=0.985). Patients carrying high-penetrance mutations exhibited a significantly higher DRR compared with those with low-penetrance variants (P=0.015). Adverse events were the only variable associated with a higher hazard of treatment withdrawal [hazard ratio (HR) 2.573 (CI: 1.223, 5.411), P=0.013] on regression analysis. A significant glucorticoid-sparing effect was observed (P<0.0001). CONCLUSIONS: IL-1 inhibitors display an excellent long-term effectiveness in terms of DRR, and their survival is not influenced by the biologic line of treatment. They display a favourable safety profile, which deserves, however, a close monitoring given its impact on treatment continuation. Special attention should be paid to molecular diagnosis and mutation penetrance, as patients carrying low-penetrance variants are more likely to interrupt treatment.

Efficacy of monoclonal anti-tumour necrosis factor-α antibodies in uveitic macular oedema.

OBJECTIVES: To assess the efficacy of anti-tumour necrosis factor (TNF)-α agents in the treatment of refractory uveitic macular oedema (UME). METHODS: Patients with refractory UME treated with TNF-α blockers were retrospectively enrolled. Central macular thickness (CMT) was assessed at optical coherence tomography (OCT) at the start of TNF-α inhibition, after 3 and 12 months, and at the last follow-up visit. RESULTS: Thirty-six patients (56 eyes with UME) were enrolled. The mean follow-up period was 29.9±40.8 (4-184) months. A statistically significant decrease was observed in the frequency of UME (p<0.0001) and in the mean CMT values (p<0.0001) during the study period. Best corrected visual acuity improved in 35 eyes (62.5%), remained stable in 12 eyes (21.4%), reduced in 9 eyes (16.1%). The mean corticosteroid dosage significantly decreased during the study period (p=0.016). CONCLUSIONS: TNF-α inhibitors represent a useful treatment in patients with severe or resistant UME.

Long-Term Outcomes of Behçet's Syndrome-Related Uveitis: A Monocentric Italian Experience.

OBJECTIVES: To examine demographic and clinical characteristics and long-term visual outcome in a cohort of Italian patients affected by Behçet's uveitis (BU). MATERIALS AND METHODS: Retrospective chart review of 47 patients with BU attending our unit between January 2018 and December 2019. Ophthalmologic manifestations, best-corrected visual acuity (BCVA), fluoroangiography and optical coherence tomography findings, and ocular complications were recorded. Predictive factors of a poor visual outcome and long-term complications were also investigated. RESULTS: Forty-seven patients (23 males and 24 females) for a total of 84 eyes were enrolled. Uveitis was bilateral in 37 (78.7%) patients with panuveitis being the most frequent anatomical pattern (40 out of 84 eyes), whereas 27 eyes presented a posterior uveitis. Isolated anterior uveitis was detected in 16 eyes. A significant improvement of median BCVA between baseline and last follow-up values was detected (p = 0.042). A higher risk of poor visual prognosis was observed in patients with uveitis duration greater than 15 years (p = 0.019). A significant resolution of retinal vasculitis was detected between baseline and last follow-up evaluation (p < 0.0001) whereas the mean ± SD macular thickness did not decrease significantly between baseline (376.00 ± 97.45 µm) and last follow-up evaluation (338.08 ± 55.81 µm). Forty-two eyes developed 57 complications during the disease course. Cataract was the most frequent (n = 12), followed by epiretinal membranes (n = 11) and cystoid macular edema (n = 6). The following variables were identified as predictors of long-term complications: human leukocyte antigen- (HLA-) B51 (p = 0.006), panuveitis (p = 0.037), and a uveitis duration of more than 15 years (p = 0.049). CONCLUSIONS: In Italian patients, BU typically arises in the third decade and predominantly manifests as a bilateral posterior uveitis or panuveitis. Its duration is associated with a poor visual prognosis. Uveitis duration, the presence of HLA-B51, and panuveitis are predictors of long-term structural complications, thus representing main drivers in the treatment decision-making.

Real-Life Data on the Efficacy of Canakinumab in Patients with Adult-Onset Still's Disease.

BACKGROUND: Interleukin-1 inhibition has revealed to be a successful treatment approach for patients with adult-onset Still's disease (AOSD). However, real-life experience is focused on the use of anakinra, while data about canakinumab (CAN) are mainly based on case reports and small case series. Patients and Methods. Patients classified with AOSD according to Yamaguchi criteria and treated with CAN were consecutively enrolled. Their clinical and therapeutic data were retrospectively collected and statistically analysed to assess the role of CAN as a therapeutic opportunity in AOSD patients in terms of clinical and laboratory disease control along with corticosteroid-sparing effect. RESULTS: Nine AOSD patients (8 females and 1 male) treated with CAN for 15.00 ± 12.3 months were enrolled. Resolution of clinical manifestations was reported in 8/9 cases at the 3-month assessment; a significant decrease in the number of tender joints (p = 0.009), swollen joints (p = 0.027), and disease activity score on 28 joints-C-reactive protein (DAS28-CRP) (p = 0.044) was observed during the study period. The systemic score of disease activity significantly decreased at the 3-month and 6-month assessments and at the last visit compared to the start of treatment (p = 0.028, p = 0.028, and p = 0.018, respectively). The daily corticosteroid dosage was significantly reduced at the 3-month and at the last follow-up visits (p = 0.017 and p = 0.018, respectively). None of the patients experienced adverse events or severe adverse events during the follow-up. CONCLUSIONS: CAN has shown prompt and remarkable effectiveness in controlling AOSD activity in a real-life contest, with a significant glucocorticoid-sparing effect and an excellent safety profile.

Role of Colchicine Treatment in Tumor Necrosis Factor Receptor Associated Periodic Syndrome (TRAPS): Real-Life Data from the AIDA Network.

OBJECTIVE: To analyze the potential role of colchicine monotherapy in patients with tumor necrosis factor receptor associated periodic syndrome (TRAPS) in terms of control of clinical and laboratory manifestations. METHODS: Patients with TRAPS treated with colchicine monotherapy were retrospectively enrolled; demographic, clinical and therapeutic data were collected and statistically analysed after having clustered patients according to different times at disease onset, penetrance of mutations, dosage of colchicine, and different disease manifestations. RESULTS: 24 patients (14 males; 15 with pediatric disease onset) treated with colchicine monotherapy were enrolled. Colchicine resulted in a complete response in 3 (12.5%) cases, partial response in 14 (58.3%) patients, and lack of response in 7 (29.2%) patients. There were not significant differences in colchicine response between pediatric and adult disease onset (p = 0.42), between low- and high-penetrance mutations (p = 0.62), and according to different dosages (p = 0.66). No significant differences were identified in the frequency of specific disease manifestations between patients experiencing any response to colchicine and patients with lack of response. CONCLUSIONS: Colchicine monotherapy is useful in a low percentage of TRAPS patients; nevertheless, it could be attempted in patients with milder phenotypes and at a lower risk of developing reactive amyloidosis.

Clinical Features at Onset and Genetic Characterization of Pediatric and Adult Patients with TNF-α Receptor-Associated Periodic Syndrome (TRAPS): A Series of 80 Cases from the AIDA Network.

This study explores demographic, clinical, and therapeutic features of tumor necrosis factor receptor-associated periodic syndrome (TRAPS) in a cohort of 80 patients recruited from 19 Italian referral Centers. Patients' data were collected retrospectively and then analyzed according to age groups (disease onset before or after 16 years) and genotype (high penetrance (HP) and low penetrance (LP) TNFRSF1A gene variants). Pediatric- and adult-onset were reported, respectively, in 44 and 36 patients; HP and LP variants were found, respectively, in 32 and 44 cases. A positive family history for recurrent fever was reported more frequently in the pediatric group than in the adult group (p < 0.05). With reference to clinical features during attacks, pericarditis and myalgia were reported more frequently in the context of adult-onset disease than in the pediatric age (with p < 0.01 and p < 0.05, respectively), while abdominal pain was present in 84% of children and in 25% of adults (p < 0.01). Abdominal pain was significantly associated also to the presence of HP mutations (p < 0.01), while oral aphthosis was more frequently found in the LP variant group (p < 0.05). Systemic amyloidosis occurred in 25% of subjects carrying HP variants. As concerns laboratory features, HP mutations were significantly associated to higher ESR values (p < 0.01) and to the persistence of steadily elevated inflammatory markers during asymptomatic periods (p < 0.05). The presence of mutations involving a cysteine residue, abdominal pain, and lymphadenopathy during flares significantly correlated with the risk of developing amyloidosis and renal impairment. Conversely, the administration of colchicine negatively correlated to the development of pathologic proteinuria (p < 0.05). Both NSAIDs and colchicine were used as monotherapy more frequently in the LP group compared to the HP group (p < 0.01). Biologic agents were prescribed to 49 (61%) patients; R92Q subjects were more frequently on NSAIDs monotherapy than other patients (p < 0.01); nevertheless, they required biologic therapy in 53.1% of cases. At disease onset, the latest classification criteria for TRAPS were fulfilled by 64/80 (80%) patients (clinical plus genetic items) and 46/80 (57.5%) patients (clinical items only). No statistically significant differences were found in the sensitivity of the classification criteria according to age at onset and according to genotype (p < 0.05). This study describes one of the widest cohorts of TRAPS patients in the literature, suggesting that the clinical expression of this syndrome is more influenced by the penetrance of the mutation rather than by the age at onset itself. Given the high phenotypic heterogeneity of the disease, a definite diagnosis should rely on both accurate working clinical assessment and complementary genotype.

Adalimumab effectively controls both anterior and posterior noninfectious uveitis associated with systemic inflammatory diseases: focus on Behçet's syndrome.

BACKGROUND: To compare the efficacy of Adalimumab (ADA) in noninfectious anterior uveitis (AU) and posterior segment (PS) involvement, associated with different conditions, with a focus on Behçet's syndrome (BS). METHODS: In this retrospective, multicenter post-hoc study, we evaluated the efficacy of ADA in terms of ocular control and relapses in 96 patients with AU and PS uveitis, either idiopathic (IU) or associated with BS or with other systemic disorders (OSD) (Juvenile Idiopathic Arthritis, Psoriatic Arthritis, Ankylosing Spondylitis, Vogt-Koyanagi-Harada, Inflammatory Bowel Disease), followed in three tertiary referral centers. RESULTS: Ninety-six patients (45 AU; 51 PS uveitis) were included. Eleven had IU, 58 BS, and 27 OSD. All patients with AU achieved complete long-term ocular control. In PS uveitis, 89%, 67% and 100% of patients with BS, IU and OSD achieved ocular control at the last follow-up (> 12 months), respectively. The lowest ocular relapse rate occurred in patients with AU with BS (1/13) or IU (0/2). ADA accounted for long-term disease control, and no predictors of ocular control and relapse were identified; particularly, ocular relapses seemed not related to systemic ones. Macular edema resolved in 75% and 67% of PS uveitis with BS and IU, respectively. CONCLUSIONS: ADA controls both anterior and posterior uveitis, with an efficacy similar in IU, BS and OSD patients. In BS, the efficacy of ADA seems to be independent of demographic and clinical characteristics, and ocular relapses mostly occurred independently from systemic ones. Based on our results, ADA may represent a valid alternative in anterior refractory uveitis.

Clinical characteristics and genetic analyses of 187 patients with undefined autoinflammatory diseases.

OBJECTIVES: To describe the clinical characteristics, treatment response and genetic findings in a large cohort of patients with undefined systemic autoinflammatory diseases (SAIDs). METHODS: Clinical and genetic data from patients with undefined SAIDs were extracted from the Eurofever registry, an international web-based registry that retrospectively collects clinical information on patients with autoinflammatory diseases. RESULTS: This study included 187 patients. Seven patients had a chronic disease course, 180 patients had a recurrent disease course. The median age at disease onset was 4.3 years. Patients had a median of 12 episodes per year, with a median duration of 4 days. Most commonly reported symptoms were arthralgia (n=113), myalgia (n=86), abdominal pain (n=89), fatigue (n=111), malaise (n=104) and mucocutaneous manifestations (n=128). In 24 patients, relatives were affected as well. In 15 patients, genetic variants were found in autoinflammatory genes. Patients with genetic variants more often had affected relatives compared with patients without genetic variants (p=0.005). Most patients responded well to non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids, colchicine and anakinra. Complete remission was rarely achieved with NSAIDs alone. Notable patterns were found in patients with distinctive symptoms. Patients with pericarditis (n=11) were older at disease onset (33.8 years) and had fewer episodes per year (3.0/year) compared with other patients. Patients with an intellectual impairment (n=8) were younger at disease onset (2.2 years) and often had relatives affected (28.6%). CONCLUSION: This study describes the clinical characteristics of a large cohort of patients with undefined SAIDs. Among these, patients with pericarditis and intellectual impairment appear to comprise distinct subsets.

Efficacy of anti-tumour necrosis factor-α monoclonal antibodies in patients with non-infectious anterior uveitis.

OBJECTIVES: To assess the efficacy of monoclonal anti-tumour necrosis factor (TNF)-α agents in patients with anterior uveitis (AU) in terms of decrease of recurrences, variation of visual acuity and steroid sparing effect and to identify any demographic, clinical or therapeutic variables associated with a sustained response to monoclonal TNF-α inhibitors. METHODS: Data from patients suffering from AU treated with adalimumab, infliximab, golimumab or certolizumab pegol were retrospectively collected and statistically analysed. RESULTS: Sixty-nine patients (22 males, 47 females), corresponding to 101 eyes, were enrolled. The mean follow-up period was 29.25±23.51 months. The rate of ocular flares decreased from 42.03 events/100 patients/year recorded during the 12 months preceding the start of TNF-α inhibitors to 2.9 flares/100 patients/year after the start of treatment (p<0.0001). The overall decrease in ocular flares was 93.1%. No statistically significant changes were identified in the best corrected visual acuity during the follow-up period (p>0.99). The number of patients treated with corticosteroids at baseline was significantly higher compared with that referred to the 12-month evaluation (p<0.001) and to the last follow-up visit (p=0.006). Concomitant treatment with conventional disease-modifying anti-rheumatic drugs (cDMARDs) represented the sole clinical, demographic or therapeutic variable associated with long-term treatment duration (p=0.045, R2=0.87). CONCLUSIONS: Monoclonal TNF-α inhibitors induce a remarkable decrease in the recurrence of AU during a long-term follow-up period and lead to a significant steroid sparing effect along with stabilisation of visual acuity. Concomitant treatment with cDMARDs represented the sole variable associated with treatment duration in the long-term.

Efficacy and safety of certolizumab pegol and golimumab in the treatment of non-infectious uveitis.

OBJECTIVES: The aim of the study was to evaluate the efficacy of golimumab (GOL) and certolizumab pegol (CZP) as additional treatment options for the treatment of uveitis. METHODS: Patients with longstanding uveitis receiving either GOL or CZP were retrospectively evaluated in terms of frequency of ocular flares, drug survival, changes in best corrected visual acuity (BCVA) and steroid-sparing effect. RESULTS: Twenty-one patients (30 eyes), 17 of whom being female, were enrolled in the study; 16 out of 21 patients had been previously treated with other tumour necrosis factor (TNF)-α blockers. A significant reduction in ocular flares (from 128.6 bouts for 100 patients-year to 42.9 events for 100 patients-year) was observed between the 12 months prior to the start of GOL or CZP and the 12 months thereafter (p=0.01). The 36-month drug survival was 54.5% for CZP and 50.0% for GOL with no statistically significant differences between the two biologic agents. No differences were detected concerning BCVA values and the mean corticosteroid intake between baseline and the last follow-up. The safety profile was excellent. CONCLUSIONS: GOL and CZP represent effective and safe treatment choices for patients with uveitis also when unsuccessfully treated with other anti-TNF-α drugs, permitting a significant reduction in the frequency of ocular flares and preserving visual function with a good long-term retention rate.

Monitoring Insulin-Aggregated Structures in the Presence of Epigallocatechin-3-gallate and Melatonin by Molecular Dynamics Simulations.

In the present work we illustrate the results of classical molecular dynamics simulations of model systems composed of six insulin molecules in water in the presence and in the absence of either epigallocatechin-3-gallate or melatonin molecules. For each model system, we performed three independent simulations (replicas) to study the aggregate formation dynamics and insulin interaction with epigallocatechin-3-gallate and melatonin. We find that melatonin is less stably close to insulin with respect to epigallocatechin-3-gallate, which interacts more stably with insulin molecules and mainly with insulin's chain B hydrophobic residues. We observe that the shape of the insulin-aggregated structures in the three model systems is different and depends on whether epigallocatechin-3-gallate is present or not. Simulations show that in the absence of epigallocatechin-3-gallate, insulin molecules tend to form linear aggregates, while in the presence of epigallocatechin-3-gallate, aggregates display a globular shape, less prone to form fibril structures.

Hints for Genetic and Clinical Differentiation of Adult-Onset Monogenic Autoinflammatory Diseases.

Monogenic autoinflammatory diseases (mAIDs) are inherited errors of innate immunity characterized by systemic inflammation recurring with variable frequency and involving the skin, serosal membranes, synovial membranes, joints, the gastrointestinal tube, and/or the central nervous system, with reactive amyloidosis as a potential severe long-term consequence. Although individually uncommon, all mAIDs set up an emerging chapter of internal medicine: recent findings have modified our knowledge regarding mAID pathophysiology and clarified that protean inflammatory symptoms can be variably associated with periodic fevers, depicting multiple specific conditions which usually start in childhood, such as familial Mediterranean fever, tumor necrosis factor receptor-associated periodic syndrome, cryopyrin-associated periodic syndrome, and mevalonate kinase deficiency. There are no evidence-based studies to establish which potential genotype analysis is the most appropriate in adult patients with clinical phenotypes suggestive of mAIDs. This review discusses genetic and clinical hints for an ideal diagnostic approach to mAIDs in adult patients, as their early identification is essential to prompt effective treatment and improve quality of life, and also highlights the most recent developments in the diagnostic work-up for the most frequent hereditary periodic febrile syndromes worldwide.
