Systemic sclerosis (SSc) is a severe chronic disease with a broad spectrum of clinical manifestations. SSc displays disturbed lymphocyte homeostasis. Immunosuppressive medications targeting T or B cells can improve disease manifestations. SSc clinical manifestations and immunosuppressive medication in itself can cause changes in lymphocyte subsets. The aim of this study was to investigate peripheral lymphocyte homeostasis in SSc with regards to the immunosuppression and to major organ involvement. 44 SSc patients and 19 healthy donors (HD) were included. Immunophenotyping of peripheral whole blood by fluorescence-activated cell sorting was performed. Cytokine secretions of stimulated B cell cultures were measured. SSc patients without immunosuppression compared to HD displayed lower γδ T cells, lower T helper cells (CD3+/CD4+), lower transitional B cells (CD19+/CD38++/CD10+/IgD+), lower pre-switched memory B cells (CD19+/CD27+/IgD+), and lower post-switched memory B cells (CD19+/CD27+/IgD−). There was no difference in the cytokine production of whole B cell cultures between SSc and HD. Within the SSc cohort, mycophenolate intake was associated with lower T helper cells and lower NK cells (CD56+/CD3−). The described differences in peripheral lymphocyte subsets between SSc and HD generate further insight in SSc pathogenesis. Lymphocyte changes under effective immunosuppression indicate how lymphocyte homeostasis in SSc might be restored. [ABSTRACT FROM AUTHOR]

To determine the prevalence of clonal T-large granular lymphocyte (T-LGL) cells in patients with spondyloarthritis (SpA) and psoriatic arthritis (PsA) and to define possible risk factors for this condition. We present a cross-sectional analysis with retrospective and prospective aspects. 115 SpA patients, 48 PsA patients and 51 controls were recruited between December 28, 2017 and January 23, 2019. Flow cytometry (FACS) was performed to screen for aberrant T-LGL cells. Molecular analysis was then employed to confirm the diagnosis in patients with suggestive FACS findings. Patients with clonal T-LGL populations were followed prospectively by FACS analysis. Electronic patient files were retrospectively analyzed to determine risk factors. Median age was 49 years for SpA, 55.5 years for PsA, and 54 years for controls. Median disease duration of SpA and PsA was 15 years and 11 years, respectively. 79.8% of patients had received biologics at some point, 75.5% had ever received tumor necrosis factor (TNF) inhibitors. 59.5% were treated with TNF inhibitors at the time of study inclusion. We identified clonal T-LGL expansions in 13 individuals equaling a prevalence of 6% (13/214). T-LGL patients were taking TNF inhibitors more frequently at the time of study inclusion (p = 0.022) and were more likely to have ever been treated with TNF inhibition (p = 0.046). Clonal T-LGL expansions can be detected in patients with SpA, PsA and also in healthy controls. Confirming earlier results, exposure to TNFα-blocking agents appears to increase the risk of developing clonal expansions of T-LGL cells. [ABSTRACT FROM AUTHOR]

The term complementary and alternative medicine (CAM) describes a broad spectrum of health care practices that are not an integral part of the conventional health care system. Many patients worldwide use CAM on their own initiative, often in combination with their conventional medical therapy. CAM use is attractive especially to patients with primary immunodeficiency, since they suffer from frequent infections and autoimmunity. Those are frequently addressed by CAM providers. The aim of this multicentric study was to collect information on the use of CAM by these patients and to define characteristics that are associated with the use of CAM. A total of 101 patients with primary immunodeficiencies at German hospitals were surveyed on their CAM use (further 14 patients rejected to participate). Multiple psychological tests (MARS-D, WHO-5, PHQ9, EFQ) were conducted to investigate variations among personality traits associated with CAM use. Additionally, clinical and sociodemographic patient data was collected. A total of 72% of patients used CAM to treat their primary immunodeficiency. The three most frequently used methods were physical exercise or fitness training (65%), dietary supplements (58%), and homeopathy (49%). Most patients did not discuss CAM use with their doctors, mostly because they felt that there was no time for it. CAM plays an important role for patients with primary immunodeficiency in a high-resource health care setting such as Germany. In clinical practice, doctors should create a platform to discuss needs that go beyond conventional therapy. [ABSTRACT FROM AUTHOR]

Objective: The goal of this study was to evaluate the long-term impact of adalimumab therapy on work-related outcomes in employed patients with rheumatoid arthritis (RA). Method: We utilized data from an observational cohort of German patients who initiated adalimumab treatment during routine clinical care. Analyses were based on employed patients (part-time or full-time) who continued adalimumab treatment for 24 months. Major outcomes were self-reported sick leave days in the previous 6 months, absenteeism, presenteeism, and total work productivity impairment as assessed by the Work Productivity and Activity Impairment (WPAI) questionnaire and disease activity assessments. The normal number of sick leave days was based on data from the German Federal Statistical Office. Results: Of 783 patients, 72.3% were women, mean age was 47.9 years, and mean disease duration was 7.8 years. At baseline (before adalimumab initiation), 42.9% of patients had higher than normal sick leave days (> 5) in the previous 6 months. During 24 months of adalimumab treatment, 61% of patients with higher than normal sick leave days at baseline returned to normal sick leave values (≤ 5 days/6 months). Overall, mean sick leave days/6 months decreased from 14.8 days at baseline to 7.4 days at month 24. Improvements were observed in WPAI assessments and disease activity measures, although presenteeism levels remained high (32.2% at month 24). Conclusions: Adalimumab treatment was associated with strong and sustained improvements in work-related outcomes in employed patients who continued on adalimumab for 24 months. Presenteeism appears to be the work outcome most resistant to improvement during RA treatment. Trial registration: NCT01076205 Key Points • Long-term adalimumab therapy was associated with sustained improvements in work outcomes in patients with rheumatoid arthritis. • Despite improvements in sick leave days and work absenteeism, presenteeism (impairment while at work) remained relatively high.

Hepatitis B virus (HBV) reactivation is a common complication of immunosuppressive treatment in high prevalence countries. Biological disease-modifying antirheumatic drugs (bDMARDs) cause this adverse event more often than conventional immunosuppressants. The incidence of HBV reactivation during treatment for rheumatic diseases in Germany is unclear. Furthermore, it remains open how to treat and monitor patients at risk during immunosuppressive therapy with bDMARDs. We examined 2054 patients from a German tertiary rheumatology center in order to analyze the prevalence of HBc-antibody-positivity and the incidence of HBV reactivation in German rheumatology patients treated with immunosuppressants. Of 1317 patients treated with bDMARDs and 737 conventional synthetic DMARD (csDMARDs) patients between 2008 and 2017, 86 had a history of HBV infection (anti-HBc positive). Only two patients were suffering from chronic infection (HBsAg positive). Three patients were treated pre-emptively with entecavir, and eight patients after HBV DNA reappearance. No liver failure occurred due to HBV reactivation. Compared to anti-HBc-positive patients without reactivation, the reactivation group included more patients exposed to three or more classes of bDMARDs (p = 0.017). The median HBs antibody titer was significantly lower in the reactivation group (15.0 IU/l vs. 293.5 IU/l; p = 0.001). This study shows that bDMARDs and csDMARDs can safely be administered to patients with a history of HBV, provided they are closely monitored. Low titers of anti-HBs antibodies and a history of ≥ 3 classes of immunosuppressants increase the risk of HBV reactivation. These data highlight major differences to high prevalence regions.
