Poor work outcomes in patients with spondyloarthritis: causes, consequences, and solutions.

BACKGROUND: Spondyloarthritis (SpA) affects patients in the prime of their economic productivity and can cause loss of work productivity and unemployment. We aim to identify factors associated with poor work outcomes in patients with SpA. METHODS: A cross-sectional study was performed in 100 patients with SpA who were employed, retired, or off work because of SpA. Data on sociodemographic and professional characteristics were collected as well as specific indices: BASDAI, ASDAS-CRP, BASFI, and BASMI. Work productivity in employed patients was assessed by the Work Productivity and Activity Impairment scale (WPAI:SpA). RESULTS: Patients were divided into 73 men and 27 women; the mean age was 43.68 ± 10.3 years. Fifty-nine percent of patients were employed and 26% were off work. The average disease duration was 12.24 ± 8.73 years. The mean BASDAI score was 4.4 ± 2.4, the average BASFI score was 4.6 ± 2.7, and the average ASDAS-CRP score was 2.77 ± 1.18. The mean BASMI was 4.4 ± 2.8. Among employed patients, the mean of absenteeism, presenteeism, and work productivity loss was 21.8 ± 33.13%, 42 ± 32%, and 46.5 ± 35.31%, respectively. In multivariable analysis, absenteeism was associated with ASDAS ≥ 2.1 (ß = 20.14), peripheral joint involvement (ß = 15.6), manual work (ß = 14.31), low level of education (ß = 7.92), and BASFI ≥ 4 (ß = 6.39). Presenteeism and work productivity loss were associated with manual work, BASFI ≥ , body mass index ≥ 25 kg/m2, smoking, the use of symptomatic treatment, and ASDAS-CRP ≥ 2.1. CONCLUSION: Spondyloarthritis affects work productivity. Screening for predictive factors should be considered by the clinician in the overall management of the disease. Key Points • SpA occurs among young and active patients; it could affect their professional lives and thus lead to loss of work productivity and unemployment. • The management of patients with SpA must be multidisciplinary; this includes assessing contextual factors in order to act on modifiable factors such as smoking and BMI, optimal management of the disease to maintain at least a low disease activity, and to ensure workstation layout and elimination of professional constraints that can affect work outcomes in patients with SpA.

Case Report: Extensive digital gangrene as a primary manifestation of late-onset systemic lupus erythematosus.

Background: Digital gangrene is a rare but serious complication of systemic lupus erythematosus (SLE). It occurs usually in middle-aged patients with longer disease duration. Case: Herein we report the case of a 56-year-old man (with no history suggestive of Raynaud's phenomenon, diabetes mellitus, smoking, trauma, infection, or chemical exposure), who presented with SLE and digital gangrene was among the first signs. He presented with a one-month history of joint pain, hair loss, photosensitivity, mouth ulcers, malar rash, dyspnea, and digital pain. Physical examination revealed painful and diffuse erythematous skin lesions in the extremities and back, as well as cyanosis in the fingers. We noted lymphocytopenia (600 cells/mm 3), and an elevated C-reactive protein (15.1 mg/l) on laboratory tests. Immunological tests were positive for antinuclear antibodies (ANA) with Title 1:400. Pulmonary computed tomography revealed pulmonary fibrosis, and pulmonary function tests revealed the restrictive pulmonary disease. Diagnosis of SLE with lung involvement was retained. The immunological assessment in search of elements in favor of a vascular origin of the patient's skin lesions was negative. Treatment was initiated with 200 mg/day hydroxychloroquine. For dermal and pulmonary involvement, intravenous (IV) pulse therapy was used with methylprednisolone (1,000 mg/d for three consecutive days monthly) and cyclophosphamide (1 g/month). Calcium blocking agents were also prescribed. However, the lesions did not improve. The patient was given two infusions of rituximab (1 g) at a 14-day interval with a marked improvement ofthe majority of vasculitis lesions, and a partial improvement of dyspnea. Conclusions: Digital gangrene is a rare complication of late-onset SLE, especially as a primary manifestation.
