Abstract [en]

Several autoimmune and inflammatory conditions, such as rheumatoid arthritis (RA) and primary Sjögrens’s syndrome (pSS), have repeatedly been linked to an increased risk of malignant lymphoma [1,2]. Certain inflammatory conditions are also associated with the development of specific lymphoma subtypes such as mucosa-associated lymphoid tissue (MALT) lymphoma in pSS and diffuse large B-cell lymphoma (DLBCL) in RA. The underlying mechanisms behind this association remain unclear. The highly increased risk of developing MALT lymphoma of the parotid gland in pSS indicates that local inflammatory processes can promote lymphoma development at the site of chronic inflammation [3]. In RA, an association between disease severity and risk of lymphoma has been shown.

Granulomatosis with polyangiitis (GPA), formerly Wegener’s granulomatosis, is a systemic small vessel vasculitis associated with the presence of anti-neutrophil cytoplasmic antibodies (ANCA) and characterized by granulomatous inflammation and necrotizing vasculitis of the airways and kidneys but possibly affecting any organ system. An increased risk of lymphoma in patients with GPA has been reported in several epidemiological studies [4,5]. However, very little is known about risk factors for lymphoma development in this group, possible relation to disease severity, treatment and lymphoma subtypes or the prognosis for the lymphomas. This is the first published study on GPA and lymphoma, giving detailed information on the GPA characteristics and possible risk factors for lymphoma and also lymphoma subtypes treatment and survival.

Abstract [en]

Objective: Systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) are autoimmune diseases that predominantly affect female patients, and therefore fewer investigations have been conducted in men. The aim of this study was to analyze sex hormone levels in male patients with SLE and those with SSc, compared to matched controls, in relation to the use of corticosteroids and cyclophosphamide (CYC).

Methods: Sex hormone levels were measured in fasting blood samples from male patients with SLE (n=71) and those with SSc (n=29) and compared to population-based, age-matched male controls. Relevant hormone profiles were identified using cluster analysis.

Results: Male SLE patients had higher levels of luteinizing hormone (LH) (P<0.0001) and more frequent bioactive testosterone deficiency (P=0.02) than their matched controls. The current dosage of prednisolone correlated inversely with the levels of bioactive testosterone (r=-0.36, P=0.03). Cluster analysis identified a subset of SLE patients with increased levels of follicle-stimulating hormone, LH, and prolactin as well as lower levels of bioactive testosterone (P<0.0001) in relation to higher daily doses of prednisolone. In male SSc patients, levels of testosterone (P=0.03) and bioactive testosterone (P=0.02) were significantly lower than those in matched controls. Use of CYC during the previous year was associated with lower bioactive testosterone levels in both SLE patients (P=0.02) and SSc patients (P=0.01), after adjustment for age.

Conclusion: The results of this study highlight the negative impact of corticosteroids on gonadal function in men with SLE. Furthermore, use of CYC during the year prior to study inclusion impaired bioactive testosterone levels in male patients with either SLE or SSc. Physicians should be more aware of the possibility of hypogonadism in male patients with autoimmune diseases. The need for hormonal supplementation remains to be formally evaluated in these patients.
