Differentiation between psoriatic arthritis (PsA) sine psoriasis and rheumatoid arthritis (RA) may be a challenge, especially in the early stages, hence the need for new instrumental markers to ...assist their diagnosis. In this study, we investigated possible dermoscopic differences in vascular appearance of nail fold and elbow (a classic site of repeated trauma) in these two conditions. Fifteen patients with PsA sine psoriasis, 12 patients with RA and 12 controls were included in the study. Regarding the nail fold vascular appearance in PsA sine psoriasis and RA cohorts, the presence of diffuse reddish background with or without sparse dotted vessels was significant in the former, whereas the evidence of parallel dotted/short linear vessels (“fish school‐like” pattern) or irregular/ramified, blurry, purple vessels were significant in the latter; none of these patterns were detected in the control group. Regarding the elbow, the pattern significantly associated with PsA sine psoriasis consisted of diffusely distributed, red, dotted vessels. On the other hand, RA patients and controls displayed similar dermoscopic findings, with three possible vascular patterns being observed: (i) irregular, blurry, purple vessels; (ii) avascular appearance; and (iii) sparse, dotted, purple vessels. In conclusion, dermoscopy may be a useful supportive tool for differentiating early PsA sine psoriasis from RA.
A few studies have reported the safety profile of interleukin (IL)-1 blockers from real life. The aim of this study is to describe anakinra (ANA) and canakinumab (CAN) safety profile in children and ...adults, based on data from a real-life setting. Demographic, clinical, and therapeutic data from patients treated with ANA and CAN were retrospectively collected and analyzed. Four hundred and seventy five patients were enrolled; ANA and CAN were prescribed in 421 and 105 treatment courses, respectively. During a mean follow-up of 24.39 ± 27.04 months, 89 adverse events (AE) were recorded; 13 (14.61%) were classified as serious AE (sAE). The overall estimated rate of AE and sAE was 8.4 per 100 patients/year. Safety concerns were more frequent among patients aged ≥ 65 years compared with patients < 16 years (
p
= 0.002). No differences were detected in the frequency of safety concerns between monotherapy and combination therapy with immunosuppressants (
p
= 0.055), but a significant difference was observed when injection site reactions were excluded from AE (
p
= 0.01). No differences were identified in relation to gender (
p
= 0.462), different lines of biologic therapy (
p
= 0.775), and different dosages (
p
= 0.70 ANA;
p
= 0.39 CAN). The overall drug retention rate was significantly different according to the occurrence of safety concerns (
p
value < 0.0001); distinguishing between ANA and CAN, significance was maintained only for ANA (
p
< 0.0001 ANA;
p >
0.05 CAN). Treatment duration was the only variable associated with onset of AE (OR = 0.399 C.I. 0.250–0.638,
p
= 0.0001). ANA and CAN have shown an excellent safety profile; the risk for AE and sAE tends to decrease over time from the start of IL-1 inhibition.
The best treatment of type II mixed cryoglobulinemia (MC) has still to be defined. Antiviral treatment for the frequent underlying infectious trigger hepatitis C virus (HCV) may be ineffective, ...contraindicated, or not tolerated in a fraction of cases, whereas current immunosuppressive treatments may lead to relevant complications. Selective B-cell blockade with rituximab was used in this study, based on favorable results in preliminary experience. Fifteen consecutive patients with type II MC (HCV-related in 12 of 15) were treated with rituximab, 375 mg/m2 intravenously weekly for 4 weeks. Only medium- to low-dose steroids were allowed, if already administered at the time of recruitment. All patients had active disease, poorly controlled or difficult to manage with previous treatments, including corticosteroids in all. Efficacy and safety of rituximab therapy were evaluated in the following 6 months. The overall follow-up after rituximab treatment ranged from 9 to 31 months. Rituximab proved effective on skin vasculitis manifestations (ulcers, purpura, or urticaria), subjective symptoms of peripheral neuropathy, low-grade B-cell lymphoma, arthralgias, and fever. Nephritis of recent onset went into remission in one case. Laboratory features, that is, significantly decreased serum rheumatoid factor and cryoglobulins and increased C4, were consistent with the clinical efficacy. Treatment was well tolerated, with no infectious complications. Thrombosis of retinal artery or self-limiting panniculitis occurred in one patient each. Rituximab may represent a safe and effective alternative to standard immunosuppression in type II MC. Controlled studies are needed to better define drug indications and the cost-efficacy profile in the different systemic manifestations.
Interleukin (IL)-1 inhibitors have been suggested as possible therapeutic options in a large number of old and new clinical entities characterized by an IL-1 driven pathogenesis.
To perform a ...nationwide snapshot of the on-label and off-label use of anakinra (ANA) and canakinumab (CAN) for different conditions both in children and adults.
We retrospectively collected demographic, clinical, and therapeutic data from both adult and pediatric patients treated with IL-1 inhibitors from January 2008 to July 2016.
Five hundred and twenty-six treatment courses given to 475 patients (195 males, 280 females; 111 children and 364 adults) were evaluated. ANA was administered in 421 (80.04%) courses, CAN in 105 (19.96%). Sixty-two (32.1%) patients had been treated with both agents. IL-1 inhibitors were employed in 38 different indications (37 with ANA, 16 with CAN). Off-label use was more frequent for ANA than CAN (p < 0.0001). ANA was employed as first-line biologic approach in 323 (76.7%) cases, while CAN in 37 cases (35.2%). IL-1 inhibitors were associated with corticosteroids in 285 (54.18%) courses and disease modifying anti-rheumatic drugs (DMARDs) in 156 (29.65%). ANA dosage ranged from 30 to 200 mg/day (or 1.0-2.0 mg/kg/day) among adults and 2-4 mg/kg/day among children; regarding CAN, the most frequently used posologies were 150mg every 8 weeks, 150mg every 4 weeks and 150mg every 6 weeks. The frequency of failure was higher among patients treated with ANA at a dosage of 100 mg/day than those treated with 2 mg/kg/day (p = 0.03). Seventy-six patients (14.4%) reported an adverse event (AE) and 10 (1.9%) a severe AE. AEs occurred more frequently after the age of 65 compared to both children and patients aged between 16 and 65 (p = 0.003 and p = 0.03, respectively).
IL-1 inhibitors are mostly used off-label, especially ANA, during adulthood. The high frequency of good clinical responses suggests that IL-1 inhibitors are used with awareness of pathogenetic mechanisms; adult healthcare physicians generally employ standard dosages, while pediatricians are more prone in using a weight-based posology. Dose adjustments and switching between different agents showed to be effective treatment strategies. Our data confirm the good safety profile of IL-1 inhibitors.
Objective: To evaluate cancer risk among individuals with connective tissue disease (CTD) in Friuli Venezia Giulia, northern Italy. Methods: A population-based cohort study was conducted based on ...data from health records available in the regional healthcare database. Demographic characteristics, hospital discharges, exemption from medical charges, drug prescriptions, were individually matched with data from the population-based cancer registry. Cancer risk was assessed in people diagnosed with the following diseases: systemic lupus erythematosus (SLE), Sjögren’s syndrome (SS), systemic sclerosis (SSc), polymyositis (PM), and dermatomyositis (DM). Results: In all, 2504 patients were followed for a total of 18,006 person-years (median follow-up: 6.8 years). After 5 and 10 years of follow-up, the cumulative cancer incidence was 2.6% and 8.5%, respectively. The most common cancers were breast (n = 34), lung (n = 24), colon–rectum–anus (n = 20), and non-Hodgkin lymphomas (NHL) (n = 20). Overall, no excess cancer risk was noted (SIR = 0.87), whereas the number of observed NHL cases was more than two-fold significantly higher than expected (SIR = 2.52). The subgroup analysis showed a higher risk of NHL among SS patients (SIR = 3.84) and SLE patients (SIR = 2.69). Conversely, the study population showed a decreased risk for breast cancers (SIR = 0.61) and corpus uteri (SIR = 0.21). Conclusions: The incidence of NHL was higher among patients with SS and SLE. Careful surveillance for hematological malignancies in these patients is recommended.
Common variable immunodeficiency disorders (CVID) are a group of rare diseases of the immune system and the most common symptomatic primary antibody deficiency in adults. The "variable" aspect of ...CVID refers to the approximately half of the patients who develop non-infective complications, mainly autoimmune features, in particular organ specific autoimmune diseases including thyroiditis, and cytopenias. Among these associated conditions, the incidence of lymphoma, including mucosal associated lymphoid tissue (MALT) type, is increased. Although these associated autoimmune disorders in CVID are generally attributed to Systemic Lupus Erythematosus (SLE), we propose that Sjogren's syndrome (SS) is perhaps a better candidate for the associated disease. SS is an autoimmune disorder characterized by the lymphocytic infiltrates of lacrimal and salivary glands, leading to dryness of the eyes and mouth. Thus, it is a lymphocyte aggressive disorder, in contrast to SLE where pathology is generally attributed to auto-antibody and complement activation. Although systemic lupus erythematosus (SLE) shares these features with SS, a much higher frequency of MALT lymphoma distinguishes SS from SLE. Also, the higher frequency of germ line encoded paraproteins such as the monoclonal rheumatoid factor found in SS patients would be more consistent with the failure of B-cell VDJ switching found in CVID; and in contrast to the hypermutation that characterizes SLE autoantibodies. Thus, we suggest that SS may fit as a better "autoimmune" association with CVID. Examining the common underlying biologic mechanisms that promote lymphoid infiltration by dysregulated lymphocytes and lymphoma in CVID may provide new avenues for treatment in both the diseases. Since the diagnosis of SLE or rheumatoid arthritis is usually based on specific autoantibodies, the associated autoimmune features of CVID patients may not be recognized in the absence of autoantibodies.
To evaluate humoral and T-cell cellular-mediated immune response after three doses of SARS-CoV-2 mRNA vaccines in patients with systemic lupus erythematosus (SLE) under Belimumab.
12 patients on ...Belimumab and 13 age-matched healthy volunteers were recruited. Patients were in remission or in low disease activity, and they were taking no corticosteroids or only low doses. None of the patients and controls had detectable anti-SARS-CoV-2 antibodies due to previous exposure to the virus. All the patients received three doses of mRNA anti-SARS-CoV-2 vaccines and the humoral and cellular-mediated response were tested 4 weeks after the second dose (T0), 6 months after the second dose (T1) and 4 weeks after the third dose (T2). Comparison with the control group was performed at time T0 (i.e., 4 weeks after the second dose). Total anti-SARS-CoV-2 RBD antibodies were analyzed using a diagnostic assay, while cellular-mediated response was evaluated using the interferon-gamma release assay (IGRA).
A humoral response was documented in all the patients at T0 (median 459; IQR 225.25-758.5), but the antibody titer significantly declined from T0 to T1 (median 44.7; IQR: 30.3-202;
= 0.0066). At T2, the antibody titer significantly increased from T1 (median 2500; IQR: 2500-2500), and it was not different from T0 (respectively
< 0.0001,
= 0.66). Cellular-mediated response significantly declined from T0 to T1 (
= 0.003) but not from T0 to T2 (
= 0.3). No differences were found between patients and controls at T0 as regards both humoral and cellular responses (
= 1.0 and
= 0.09 for humoral and cellular responses, respectively).
The third dose of mRNA COVID-19 vaccine can restore both humoral and cellular immune response in SLE patients on Belimumab.
Inborn errors of immunity (IEI) associated with immune dysregulation are not sufficiently addressed in shared recommendation, resulting in delayed diagnosis and high morbidity. The availability of ...precision medicine for some of these immune defects makes it urgent to evaluate effective strategies to diagnose and treat such defects before the occurrence of severe complications. A diagnosis of an IEI in these patients enabled the use of a more specific treatment in most cases, and these have the potential to prevent further disease progression. We studied immune dysregulation diseases in 30 patients with autoimmune or allergic phenotypes, exploiting data from clinics and immunophenotype, genetic and transcriptome investigations, and 6 of them were diagnosed with a monogenic disorder. Our results confirm that a non-negligible number of children with IEIs may present with signs and symptoms of immune dysregulation and share many features with common multifactorial immune conditions. Reaching a genetic diagnosis becomes more likely in the presence of multiple clinical manifestations, especially when in association with abnormalities of lymphocytes subsets and/or immunoglobulins levels. Moreover, 5 of 6 patients that obtained a diagnosis of monogenic disorder received precision therapy, in four cases with a good or moderate response.
Objective
To explore the experience of patients with systemic lupus erythematosus (SLE).
Methods
A systematic review of qualitative studies published in English in the past 10 years and identified ...through the PubMed, CINAHL, Scopus, and Web of Science databases was performed following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. The methodologic quality of each included study was assessed using the Critical Appraisal Screening Programme tool. Study findings were then subjected to a meta‐summary and meta‐synthesis.
Results
Twenty‐six studies with a good overall methodologic quality were included, documenting the experience of 565 adult patients (95% women). A total of 17 codes emerged, summarizing the life experience of SLE patients; the most and least frequent codes in the meta‐summary were “feeling not as I usually do” (69.2%) and “having wishes” (7.7%). The codes were then categorized into 5 main themes, summarizing the experience of living with SLE: 1) “experiencing waves of emotions due to the unpredictable nature of the disease,” 2) “trying to live an ordinary life,” 3) “listening to and obeying the body's limitations,” 4) “reviewing my life projects,” and 5) “dealing with future uncertainties.”
Conclusion
Several qualitative studies have been published to date using good methodologic approaches. According to the findings, SLE negatively impacts patient experiences by affecting multiple dimensions of their daily lives, with fatigue and pain as the most frequent symptoms.
To evaluate B-cell- and T-cell-mediated immune response to SARS-CoV-2 mRNA vaccination in patients with complex or rare systemic autoimmune diseases previously been treated with or under continuous ...treatment with B-cell-targeted therapies including rituximab (RTX) and belimumab (BEL).
Twenty-eight consecutive patients receiving RTX (n = 11) or BEL (n = 17) treatment and 13 age-/sex-matched controls (non-rheumatic healthcare personnel) were recruited. None of the patients had detectable anti-SARS-CoV-2 antibodies caused by prior exposure to the virus. All the patients and controls received mRNA vaccines and were tested three to four weeks after completion of vaccination. In all the RTX patients, vaccination was started within 5 months from the last infusion, and B-cell depletion was confirmed in all but one of them. Total anti-SARS-CoV-2 RBD antibodies were analyzed using a diagnostic assay, while T-cell response was evaluated using the interferon-gamma release assay (IGRA). Further, SARS-CoV-2 pseudoviruses were employed to verify the strain-specific neutralizing capacity of the antibodies.
Detectable anti-SARS-CoV-2 antibodies were documented in 1 out of the 11 RTX patients and 16 of the 17 BEL patients. The median concentration in the RTX and BEL patients was significantly lower than that in the controls (39.6 AU/ml vs. 1133 AU/ml, p = 0.002). The result of IGRA was positive in 8 of the 11 (72.7%) RTX patients and 16 of the 17 (94.1%) BEL patients, and interferon release in both the RTX and BEL patients was comparable to that in the control participants.
B-cell-targeted therapies do not preclude SARS-CoV-2 vaccination, since virus-specific cellular immunity can be induced even in the absence of circulating B cells. An important finding was that lupus patients treated with BEL developed immune responses to SARS-CoV-2; this indicates retention of the immunogenicity of the COVID-19 vaccine.
