Objectives: Belimumab has recently been approved for the treatment of systemic lupus erythematosus (SLE) refractory to standard therapy. Following one case of an SLE flare after cessation of belimumab, we hypothesized that this might lead to a rebound phenomenon and possible exacerbation of SLE.Method: Members of the Israeli Society of Rheumatology were contacted by e-mail and asked to report cases of an SLE flare following cessation of belimumab treatment.Results: Three cases of SLE patients who experienced a severe SLE flare following cessation of belimumab therapy were reported. In all cases, belimumab was given as treatment for active mucocutaneous manifestations and/or polyarthritis with improvement in all three patients, one of whom achieved disease remission. In all three cases, patients experienced a severe flare in previously uninvolved major organ systems, including one case of class IV lupus nephritis accompanied by a new-onset severe headache with elevated cerebrospinal fluid (CSF) protein and white matter lesions on brain magnetic resonance imaging (MRI), one case of severe pneumonitis and haemolytic anaemia, and one case of a systemic flare, fatigue, arthritis, and severe abdominal pain.Conclusions: Belimumab therapy has been shown to be beneficial in the management of active SLE, mostly in patients with mucocutaneous and musculoskeletal manifestations. We suggest a possible rebound effect following cessation of belimumab that could be due to an increase in B-cell activating factor (BAFF) levels and lead to a disease flare. Future assessment of BAFF levels in patients stopping belimumab therapy and clinical correlation may support this hypothesis. Further studies are needed to confirm this observation.

Objectives: To study the association between traditional disease-modifying antirheumatic drugs (c-DMARD) or anti-TNF-α agents and herpes zoster (HZ) in patients with psoriatic arthritis (PsA).Methods: A retrospective cohort study was conducted in patients with PsA between 2002 and 2013. Patients were grouped as follows: no DMARDs (Group A); c-DMARDs (Group B); anti-TNF-α agents (Group C); anti-TNF-α agents in combination with c-DMARDs (Group D). Crude incidence rates (IR) were calculated as number of HZ episodes per 1000 patient-years. A Cox regression model was used to adjust for HZ risk factors (age, gender, steroid use, Charlson Comorbidity Index score, and previous treatment) in order to estimate their contribution to the risk of the first HZ event.Results: The study included 3128 patients, mean age 50.26±14.54 years; 46.2% male. During a period of 20 096 person-years 182 HZ events were observed. The crude IR (95% CI) of HZ in the study population was 9.06 per 1000 patient-years, and in Groups A-D 7.36 (5.41 to 9.79), 9.21 (7.5 to 11.21), 8.64 (4.84 to 14.26), 17.86 (10.91 to 27.58), respectively. In a multivariate analysis, age (HR 1.01, 95% CI 1.00 to 1.02), treatment with steroids (HR 1.08, 95% CI 1.04 to 1.13), and a combination of anti-TNF-α agents and c-DMARDs (HR 2.37, 95% CI 1.32 to 4.22) were significantly associated with HZ events.Conclusions: In our database, the risk of HZ was significantly increased with age, treatment with steroids, and combination of anti-TNF-α agents and c-DMARDs, but not with c-DMARDs or anti-TNF-α therapy alone. Time to HZ event was shorter in patients treated with anti -TNF-α agents. [ABSTRACT FROM AUTHOR]

The article discusses a study by C.R. Juhl and others published within the periodical related to assessment of growing evidence of risk factors associated with coronary artery disease in patients with severe hidradenitis suppurativa (HS). Topics discussed include higher mean heart rate among people with HS compared when adjusting for sex and age in univariate analysis, higher body mass index and increased risk of cardiovascular mortality and sudden death.
