Systemic lupus erythematosus (SLE) in males and especially in the elderly is infrequent. We describe two male patients over 65 years old, who presented with anaemia, cytopenia, nephritis, and serositis, suggesting that they suffered from an autoimmune disease. Following an interval of 6 and 9 years respectively, the diagnosis of SLE was made. In both patients, hypothyroidism, and eye involvement (uveitis and iridocyclitis) were present indicating autoimmune activity or even a new autoimmune syndrome. One patient was treated with corticosteroids and azathioprine upon which he developed many side effects from the steroid therapy. The other patient received treatment with intravenous immunoglobulin (IVIG), and at a follow-up period of 18 months, the patient's condition remained stable. We suggest that in the constellation of clinically multiple organ involvement in the elderly male, the diagnosis of SLE should be considered. IVIG may be a successful alternative therapy in this subset of patients.

Compared to the now numerous studies on the endocrinology of rheumatic diseases in adults, only a small number of studies has been published on children with rheumatic diseases. Prolactin has been most extensively investigated, showing interesting parallels with the findings in adults with rheumatological diseases. Thus, analogous to adult RA most forms of JRA or JCA (with the exception of ANA-positive JRA with uveitis) appear to show, if anything, low to normal levels of prolactin. Since the prolactin levels in adult RA depend on the inflammatory activity, and the physiological prolactin secretion decreases in chronic stress (especially sleep disorders), these results are most likely to be explained as reactive non-specific mechanisms in the stress of the disease. However, specific mechanisms are also being discussed to explain the low prolactin levels in adult RA. The results of prolactin measurements in juvenile SLE, juvenile ankylosing spondylitis and ANA-positive JRA with a raised incidence of uveitis, contrast with this. These conditions sometimes show significantly higher prolactin levels compared to healthy controls. A correlation of the increase of prolactin concentration with the inflammatory activity has been described for juvenile ankylosing spondylitis. These results correlate well with those of adult forms such as diseases of the seronegative spondyloarthropathies type, SLE and iridocyclitis. Raised prolactin concentrations are also found in these diseases. The inflammation promoting and immunostimulatory effects of prolactin found especially in animal experiments are confirmed clinically in these diseases by reports of successful treatments with the prolactin inhibitor, bromocriptine. The results available up to now for human growth hormone in JRA and JCA tend to be comparable with the results for prolactin in these form of paediatric rheumatological diseases. Besides normal values above, all lowered concentrations are measured for this hormone. Apart from other non-specific factors, its diminished secretion is mainly determined by the inflammatory activity of the disease. Low levels of growth hormone are likely to be a significant factor in the growth retardation in children with inflammatory rheumatological diseases. Up to now, the small number of investigations on gonadotrophins and the sex hormones in juvenile SLE and various forms of JRA published have not as yet yielded unequivocal results. The endocrine aspects of paediatric rheumatological diseases are thus still incompletely elucidated. However, there are many promising avenues for further fruitful research in this field.

A patient was identified with an unusual autoimmune syndrome consisting of systemic lupus erythematosus and sarcoidosis. Her serum contained extremely high levels of autoantibodies to the DEK protooncogene product. The patient's serum was used to clone a dek complementary DNA, which was expressed as a histidine-tagged fusion protein in Escherichia coli. Using affinity-purified recombinant DEK protein, anti-DEK autoantibodies were found in the patient's serum at a titer of 1:10(6) by enzyme-linked immunosorbent assay (ELISA). Longitudinal studies revealed marked variations in anti-DEK autoantibody levels over time. Although it has been suggested that anti-DEK autoantibodies are a marker for pauciarticular juvenile rheumatoid arthritis with iridocyclitis, the present data suggest that they may be associated with other disease subsets as well. The quantitative ELISA technique will be useful for defining these subsets further and for examining the relationship between anti-DEK titers and disease activity.

Juvenile arthritis implies an onset of disease under 16 years with arthritis persisting in one or more joints for at least six weeks, and with the active exclusion of well defined illnesses, such as systemic lupus erythematosus. Prognosis implies the ability to predict outcome. Its accuracy depends on many factors with early recognition and appropriate care being important. However, response to treatment may be variable. In general, those with involvement of a few joints do better than those with systemic disease or seropositive juvenile rheumatoid arthritis both with regard to persistence of disease activity and complications. These include not just joint deformities, but osteoporosis, amyloidosis, alterations in growth with overall failure and local anomalies, chronic iridocyclitis and psychosocial problems. More aggressive therapy was only introduced in the 1990's, so it is important that multicentre studies are properly assessed in the context of the suggested International diagnostic criteria. One hundred years ago, George Fredric Still drew attention to the systemic form of the disease as distinct from pure polyarthritis [1], but it was only in the 1970s, as follow-up proceeded, that the separate identity of variants became clinically evident [2]. At the Park City meeting [3] and at the EULAR meeting in 1977 [4] when three subgroups (notably systemic, polyarthritis and pauci-articular onset) were defined, that subclassification became regularly used. However, since there were no absolute diagnostic tests there had to be exclusions. At that time the most common medications were aspirin and corticosteroids, although a few patients received gold or penicillamine. In their large group Wallace and Levinson (1990) [5] found that at the 10 year follow-up between 31% and 55% still had active disease. Girls appeared to have a five-fold greater risk for persistent activity than boys; disease duration was probably the most important factor influencing disease activity at follow-up as suggested previously [6]. It was not until the 1990's that the more aggressive therapy in the form of methotrexate--which Giannini had shown to be effective when given in appropriate dosage [7]--and sulphasalazine [8] and the long acting local corticosteroid triamcinolone hexatonide became regularly employed [9, 10]. At the ILAR Meeting in 1993 an international task force was set up under the chairmanship of Dr. C. Fink [11] to develop a classification for the idiopathic arthritides in children, defining childhood as up to 16 years of age. Active exclusion of well-recognised disorders such as rheumatic fever or systemic lupus erythematosus, still had to be made. The first proposed types, which are mutually exclusive, are shown in Table 1. A more recent meeting in Durban under the chairmanship of Dr. R. Petty is yet to be published, but considerable advances have been made, particularly in the definition of subgroups.

Autoantibodies against the transcriptional DEK protein have been considered characteristic of the pauciarticular onset subtype of juvenile rheumatoid arthritis (JRA) associated with iridocyclitis in young girls. In this study we investigated the presence of anti-DEK autoantibodies in the sera of 288 patients with SLE using a recombinant DEK protein as autoantigenic target. Thirty sera (10.4%) were positive against DEK protein by immunoblotting. Patients with anti-DEK autoantibodies show a lower frequency of cutaneous manifestation, exhibit more frequently certain markers of a chronic inflammatory status like anaemia and positivity for C-reactive protein, as well as a higher frequency of anti-double-stranded DNA autoantibodies. In contrast to JRA patients positive for anti-DEK autoantibodies, no association with erosive arthritis nor iridocyclitis were found in SLE. In conclusion, our results show that 10.4% of SLE patients from our area show antibodies against DEK protein, although this feature did not clearly establish a clinical subset of the disease.

Blindness caused by severe vasculitis or uveitis is rare in juvenile systemic lupus erythematosus (JSLE) patients. In a 27-year period, 5367 patients were followed at our Paediatric Rheumatology Division and 263 (4.9%) patients had JSLE (American College of Rheumatology criteria). Of note, two (0.8%) of them had irreversible blindness. One of them presented with cutaneous vasculitis and malar rash, associated with pain and redness in both eyes, impairment of visual acuity due to iridocyclitis and severe retinal vasculitis with haemorrhage. Another patient had peripheral polyneuropathy of the four limbs and received immunosuppressive drugs. Three weeks later, she developed diffuse herpes zoster associated with acute blindness due to bilateral retinal necrotizing vasculitis compatible with varicella zoster virus ocular infection. Despite prompt treatment, both patients suffered rapid irreversible blindness. In conclusion, irreversible blindness due to retinal vasculitis and/or uveitis is a rare and severe lupus manifestation, particularly associated with disease activity and viral infection.

Vitamin D plays a key role in in calcium homeostasis and, thus, provides an important support in bone growth by aiding in the mineralization of the collagen matrix. However, vitamin D performs various immunomodulatory, anti-inflammatory, antioxidant and anti-fibrotic actions. Autoimmune diseases result from an aberrant activation of the immune system, whereby the immune response is directed against harmless self-antigens. Does vitamin D play a role in the pathophysiology of autoimmune diseases? And, if so, what is its role? In the last decade, researchers' interest in vitamin D and its correlations with autoimmune diseases has considerably increased. We conducted a literature review, covering the period January 1, 2009 through March 30, 2019, in PubMed. We analyzed more than 130 studies in order to find a correlation between vitamin D levels and its effect upon several autoimmune diseases. The analysis demonstrated an inverse association between vitamin D and the development of several autoimmune diseases, such as SLE, thyrotoxicosis, type 1 DM, MS, iridocyclitis, Crohn's disease, ulcerative colitis, psoriasis vulgaris, seropositive RA, polymyalgia rheumatica. International multicenter study could allow us to confirm the data already present in the literature in the single clinical studies and to evaluate when to effectively supplement vitamin D in patients who do not take corticosteroids.
