Abstract
AIM To study the frequency of hypogonadism (HG) in men with rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) and to evaluate the impact of HG on the course of RA and and concomitant diseases. MATERIALS AND METHODS A single-stage continuous study included 170 men with RA, 57 men with AS and 85 men with PsA, who were hospitalized at the Nasonova Research Institute of Rheumatology. Patients were assessed for total testosterone (ТS) levels and subsequently divided into subgroups with normal (>12 nmol/l) and reduced levels. An intergroup comparison was carried out on the main indicators used in clinical rheumatological practice to assess the stage, activity and other medical and demographic characteristics of rheumatic disease, as well as on concomitant conditions. The second stage of the study involved a pairwise intergroup comparison among patients with HG with RA, AS and PsA. RESULTS The incidence of ТS deficiency among patients with RA was 24.1%, among patients with AS - 17.5%, and with PsA - 31.8%. In patients with RA, HG was associated with a significantly higher mean body mass index, higher fasting blood glucose and uric acid, higher erythrocyte sedimentation rate and anemia. Patients with AS with HG had significantly lower hemoglobin levels and more frequent anemia, as well as higher levels of C-reactive protein and erythrocyte sedimentation rate. In PsA, older age was observed in the androgen deficiency group, as well as higher body mass index and fasting glucose levels; obesity was more common. An intergroup comparison of quantitative and qualitative indicators between patients with androgen deficiency in all three rheumatic diseases (RDs) did not reveal significant differences in the average concentrations of ТS, luteinizing hormone, sex hormone binding globulin, experience of RD, laboratory markers of inflammatory activity, as well as glucose and uric acid. A similar incidence of diabetes mellitus, obesity and anemia was noted for all three nosologies. CONCLUSION ТS levels and the presence of HG were not associated with the stage and activity of RD, but ТS deficiency was accompanied by higher laboratory indicators of inflammatory activity, lower hemoglobin values, and metabolic disorders. Patients with HG, regardless of nosology, had similar levels of sex hormones and indicators reflecting RD and concomitant conditions.

Abstract
Background Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with a remarkable predominance in female, suggesting that steroid hormones may be involved in the pathogenesis. However, steroid signature of SLE patients has not been fully explored. Methods A metabolic profiling analysis based on gas chromatography/mass spectrometry (GC/MS) with high sensitivity and reproducibility was employed to comprehensively reveal SLE-specific steroid alterations. Results More than 70 kinds of steroids in urine were detected by gas chromatography/mass spectrometry (GC/MS) to reveal SLE-specific steroid alterations. Principle component analysis demonstrated that the steroid profile was obviously distinguished between patients with SLE and controls. A lower level of total androgens was observed in patients, and nine androgens [dehydroepiandrosterone (DHEA), testosterone, Etio, androsterone, βαβ-Diol, Epi-An, Epi-DHT, 16α-OH-DHEA, and A-Diol] underwent significant decrease. Moreover, patients with SLE exhibited a slightly higher level of total estrogens than controls, and three estrogens (17-Epi-E3, 17α-E2, and E3) were remarkably increased. Furthermore, we identified the elevation of two sterols (Lan and Chol), and the reduction of one corticoid (11-DeoxyF) and two progestins (5α-DHP and 11β-OH-Prog) in patients. Discussion In this study, metabolic signature of urinary steroids associated with SLE was comprehensively defined by GC/MS for the first time, and steroid metabolism disorders were found in patients with SLE, especially the conversion of androgens to estrogens. Our findings will provide new insights for a deeper understanding of the mechanism of steroid hormones in the pathogenesis of SLE and will help to unravel the reason of sexual disparity in SLE.

Abstract
Importance Low testosterone levels in males have been linked with increase in proinflammatory cytokines—a primary culprit in COVID‐19 disease progression—and with adverse COVID‐19 outcomes. To date, however, no published studies have assessed the effect of testosterone therapy on COVID‐19 outcomes in older men. Objective To examine whether testosterone therapy reduced disease progression in older men diagnosed with COVID‐19. Design, setting, and participants Nested within a national cohort of older (aged ≥50 years) male patients diagnosed with COVID‐19 between January 1, 2020 and July 1, 2021 from the Optum electronic health record COVID‐19 database, two matched case–control studies of COVID‐19 outcomes were conducted. Cases—defined, respectively, as persons who (a) were hospitalized ≤30 days after COVID‐19 diagnosis (n = 33,380), and (b) were admitted to the intensive care unit or received mechanical ventilation during their COVID‐19 hospitalization (n = 10,273)—were matched 1:1 with controls based on demographic and clinical factors. Exposures Testosterone therapy was defined based on receipt of prescription at ≤60, ≤90, or ≤120 days before COVID‐19 diagnosis. Main outcomes and measures Adjusted odds ratios (ORs) for the risk of hospitalization within 30 days of COVID‐19 diagnosis and intensive care unit admission/mechanical ventilation during COVID‐19 hospitalization. Results The use of testosterone therapy was not associated with decreased odds of hospitalization (≤60 days: OR = 0.92, 95% confidence interval [CI] = 0.70–1.20; ≤90 days: OR = 0.87, 95% CI = 0.68–1.13; ≤120 days: OR = 0.97, 95% CI = 0.72–1.32) or intensive care unit admission/mechanical ventilation (≤60 days: OR = 0.67, 95% CI = 0.37–1.23; ≤90 days: OR = 0.63, 95% CI = 0.36–0.11; ≤120 days: OR = 0.58, 95% CI = 0.29–1.19). Conclusions and relevance This study showed that testosterone therapy was not associated with decreased risks of COVID‐19 adverse outcomes. These findings may provide clinically relevant information regarding testosterone treatment in older men with COVID‐19 and other respiratory viral infections with similar pathogenesis.

Abstract
Sexual dimorphism refers to differences between biological sexes that extend beyond sexual characteristics. In humans, sexual dimorphism in the immune response has been well demonstrated, with females exhibiting lower infection rates than males for a variety of bacterial, viral, and parasitic pathogens. There is also a substantially increased incidence of autoimmune disease in females compared to males. Together, these trends indicate that females have a heightened immune reactogenicity to both self and non-self-molecular patterns. However, the molecular mechanisms driving the sexually dimorphic immune response are not fully understood. The female sex hormones estrogen and progesterone, as well as the male androgens, such as testosterone, elicit direct effects on the function and inflammatory capacity of immune cells. Several studies have identified a sex-specific transcriptome and methylome, independent of the well-described phenomenon of X-chromosome inactivation, suggesting that sexual dimorphism also occurs at the epigenetic level. Moreover, distinct alterations to the transcriptome and epigenetic landscape occur in synchrony with periods of hormonal change, such as puberty, pregnancy, menopause, and exogenous hormone therapy. These changes are also mirrored by changes in immune cell function. This review will outline the evidence for sex hormones and pregnancy-associated hormones as drivers of epigenetic change, and how this may contribute to the sexual dimorphism. Determining the effects of sex hormones on innate immune function is important for understanding sexually dimorphic autoimmune diseases, sex-specific responses to pathogens and vaccines, and how innate immunity is altered during periods of hormonal change (endogenous or exogenous).

Abstract
BACKGROUND Androgen insensitivity syndrome (AIS) is a rare X-linked genetic disease and one of the causes of 46,XY disorder of sexual development. The unstraightforward diagnosis of AIS and the gender assignment dilemma still make a plague for this disorder due to the overlapping clinical phenotypes. METHODS Peripheral blood mononuclear cells (PBMCs) of partial AIS (PAIS) patients and healthy controls were separated, and RNA-seq was performed to investigate transcriptome variance. Then, tissue-specific gene expression, functional enrichment, and protein-protein interaction (PPI) network analyses were performed; and the key modules were identified. Finally, the RNA expression of differentially expressed genes (DEGs) of interest was validated by quantitative real-time PCR (qRT-PCR). RESULTS In our dataset, a total of 725 DEGs were captured, with functionally enriched reproduction and immune-related pathways and Gene Ontology (GO) functions. The most highly specific systems centered on hematologic/immune and reproductive/endocrine systems. We finally filtered out CCR1, PPBP, PF4, CLU, KMT2D, GP6, and SPARC by the key gene clusters of the PPI network and manual screening of tissue-specific gene expression. These genes provide novel insight into the pathogenesis of AIS in the immune system or metabolism and bring forward possible molecular markers for clinical screening. The qRT-PCR results showed a consistent trend in the expression levels of related genes between PAIS patients and healthy controls. CONCLUSION The present study sheds light on the molecular mechanisms underlying the pathogenesis and progression of AIS, providing potential targets for diagnosis and future investigation.

Abstract
The association between hypogonadotropic hypogonadism and juvenile chronic arthritis has rarely been reported in the literature. We report an untreated case of systemic juvenile idiopathic arthritis in a young African male with co-presentation of hypogonadotropic hypogonadism. Possible pathophysiological and etiological links are discussed. A 16-year-old boy was received in our outpatient department for chronic arthritis with temporomandibular involvement and fever. There was no family history of rheumatic diseases or psoriasis. Body temperature was 39.5°C at admission. The clinical examination found synovitis of wrists and knees and inflammatory lymphadenopathy. This polyarthritis occurred in a context of hypogonadism marked by impuberism of Tanner classification stage P2G2. Laboratory tests showed biological inflammatory syndrome and hyperferritinemia with collapsed glycosylated ferritin at 11%. Hormonal testing found low blood testosterone (0.08 mg/L) and pituitary hormone levels attesting to hypogonadotropic hypogonadism. Screening for infections was negative. The immunological assessment for antinuclear antibodies, rheumatoid factor, and anti-cyclic citrullinated peptide antibodies were negative. Standard radiography showed bilateral wrist carpitis. The olfactory bulb was present and normal by cerebral magnetic resonance imaging. The diagnosis of systemic juvenile idiopathic arthritis associated with hypogonadotropic hypogonadism, probably related to delayed puberty, was retained. A therapy combining corticosteroid, methotrexate for arthritis, and hormone replacement with testosterone led to regression of arthritis, biological inflammatory syndrome, and hypogonadism. The presence of rheumatic disease in this context of hypogonadism, regardless of its cause, is mainly associated with very low testosterone levels and the presentation of arthritis in these patients tends to be more severe.

Abstract
BACKGROUND Central nervous system damage in multiple sclerosis (MS) is responsible for serious deficiencies. Current therapies are focused on the treatment of inflammation; however, there is an urgent need for innovative therapies promoting neuroregeneration, particularly myelin repair. It is demonstrated that testosterone can act through neural androgen receptors and several clinical observations stimulated an interest in the potential protective effects of testosterone treatment for MS. Here, we sought to demonstrate the effects of a testosterone supplementation in testosterone-deficient men with relapsing-remitting MS. METHODS/DESIGN This report presents the rationale and methodology of TOTEM RRMS, a French, phase 2, multicenter, randomized, placebo-controlled, and double-blind trial, which aims to prevent the progression of MS in men with low testosterone levels by administration of testosterone undecanoate, who were kept under natalizumab (Tysabri®) to overcome the anti-inflammatory effect of testosterone. Forty patients will be randomized into two groups receiving either a testosterone treatment (Nebido®) or a matching placebo. The intervention period for each group will last 66 weeks (treatment will be injected at baseline, week 6, and then every 12 weeks). The main objective is to determine the neuroprotective and remyelinating effects of testosterone using tensor diffusion imaging techniques and thalamic atrophy analyses. As secondary objectives, impacts of the testosterone supplementation will be studied using other conventional and unconventional MRI parameters and with clinical outcomes. DISCUSSION The action of testosterone is observed in different experimental autoimmune encephalomyelitis models and epidemiological studies in humans. However, despite several preclinical data and some small clinical trials in MS, clear evidence for a therapeutic effect of hormone therapy is still missing. Therefore, our goal is to demonstrate the effects of testosterone therapies in MS. As there is no effective treatment currently available on fatigue in MS, careful attention should also be paid to secondary endpoints: fatigue, cognitive functions, and other symptoms that may improve life quality. Assuming a positive outcome of the trial, this treatment could be considered as a new neuroprotective and remyelinating therapy in relapsing-remitting MS and could be applicable to other demyelinating diseases.

Abstract
Prostate cancer affects African Americans disproportionately by exhibiting greater incidence, rapid disease progression, and higher mortality when compared to their Caucasian counterparts. Additionally, standard treatment interventions do not achieve similar outcome in African Americans compared to Caucasian Americans, indicating differences in host factors contributing to racial disparity. African Americans have allelic variants and hyper-expression of genes that often lead to an immunosuppressive tumor microenvironment, possibly contributing to more aggressive tumors and poorer disease and therapeutic outcomes than Caucasians. In this review, we have discussed race-specific differences in external factors impacting internal milieu, which modify immunological topography as well as contribute to disparity in prostate cancer.

[PMID: 30558178 PMCID: PMC6306858 DOI: 10.3390/jcm7120549] [Citation(s) in RCA: 69] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2018] [Revised: 12/09/2018] [Accepted: 12/11/2018] [Indexed: 12/20/2022] Open
Abstract
The role of testosterone in the pathophysiology of inflammation is of critical clinical importance; however, no universal mechanism(s) has been advanced to explain the complex and interwoven pathways of androgens in the attenuation of the inflammatory processes. PubMed and EMBASE searches were performed, including the following key words: "testosterone", "androgens", "inflammatory cytokines", "inflammatory biomarkers" with focus on clinical studies as well as basic scientific studies in human and animal models. Significant benefits of testosterone therapy in ameliorating or attenuating the symptoms of several chronic inflammatory diseases were reported. Because anti⁻tumor necrosis factor therapy is the mainstay for the treatment of moderate-to-severe inflammatory bowel disease; including Crohn's disease and ulcerative colitis, and because testosterone therapy in hypogonadal men with chronic inflammatory conditions reduce tumor necrosis factor-alpha (TNF-α), IL-1β, and IL-6, we suggest that testosterone therapy attenuates the inflammatory process and reduces the burden of disease by mechanisms inhibiting inflammatory cytokine expression and function. Mechanistically, androgens regulate the expression and function of inflammatory cytokines, including TNF-α, IL-1β, IL-6, and CRP (C-reactive protein). Here, we suggest that testosterone regulates multiple and overlapping cellular and molecular pathways involving a host of immune cells and biochemical factors that converge to contribute to attenuation of the inflammatory process.

Abstract
INTRODUCTION Neuroprotection and remyelination are two unmet needs in the treatment of multiple sclerosis (MS). Therapeutic potential has been identified with sexual hormones, supported in women by a decrease in MS activity during the pregnancy, in men by a greater severity of symptoms and a faster progression than in women. Areas covered: The therapeutic effect of testosterone and estrogens is reviewed. Both hormones have demonstrated an anti-inflammatory effect. Testosterone has an effect in protecting neurons in culture against glutamate-induced toxicity and oxidative stress, and stimulates myelin formation and regeneration mediated through the neural androgen receptor. In experimental autoimmune encephalomyelitis model, estrogens significantly decrease inflammation in the central nervous system via ERα, while its action on ERβ leads to myelin and axon reparation. Estriol therapy in two phase 2 trials showed a decrease in clinical disease activity and inflammatory parameters in MRI. However, evidence of a therapeutic effect of testosterone is scarce. Expert commentary: Phase 3 trials with estriol as an add-on supplementation are now mandatory. Testosterone is another candidate to be tested in phase 2 trials. These hormones should be considered as an adjunctive therapy. New validated tools are needed to assess their effect on neuroprotection and remyelination.

Abstract
In addition to determining biological sex, sex hormones are known to influence health and disease via regulation of immune cell activities and modulation of target-organ susceptibility to immune-mediated damage. Systemic autoimmune disorders, such as systemic lupus erythematosus, rheumatoid arthritis, and multiple sclerosis are more prevalent in females, while cancer shows the opposite pattern. Sex hormones have been repeatedly suggested to play a part in these biases. In this review, we will discuss how androgens and the expression of functional androgen receptor affect immune cells and how this may dampen or alter immune response(s) and affect autoimmune disease incidences and progression.

Abstract
OBJECTIVE Sjögren's syndrome (SS) and systemic lupus erythematosus (SLE) are related by clinical and serologic manifestations as well as genetic risks. Both diseases are more commonly found in women than in men, at a ratio of ~10 to 1. Common X chromosome aneuploidies, 47,XXY and 47,XXX, are enriched among men and women, respectively, in either disease, suggesting a dose effect on the X chromosome. METHODS We examined cohorts of SS and SLE patients by constructing intensity plots of X chromosome single-nucleotide polymorphism alleles, along with determining the karyotype of selected patients. RESULTS Among ~2,500 women with SLE, we found 3 patients with a triple mosaic, consisting of 45,X/46,XX/47,XXX. Among ~2,100 women with SS, 1 patient had 45,X/46,XX/47,XXX, with a triplication of the distal p arm of the X chromosome in the 47,XXX cells. Neither the triple mosaic nor the partial triplication was found among the controls. In another SS cohort, we found a mother/daughter pair with partial triplication of this same region of the X chromosome. The triple mosaic occurs in ~1 in 25,000-50,000 live female births, while partial triplications are even rarer. CONCLUSION Very rare X chromosome abnormalities are present among patients with either SS or SLE and may inform the location of a gene(s) that mediates an X dose effect, as well as critical cell types in which such an effect is operative.

Abstract
Abstract
The article summarizes data on the association of Klinefelter syndrome (KS) with autoimmune rheumatic diseases, that is rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), polymyositis/dermatomyositis, systemic sclerosis (SSc), mixed connective tissue diseases (MCTD), Sjogren’s syndrome and antiphospholipid syndrome (APS). Recently, a higher risk for RA, SLE and Sjogren’s syndrome in patients with KS has been clearly demonstrated. However, the association of other autoimmune rheumatic disorders such as dermatomyositis/polymyositis, SSc, MCTD and APS is reported only casually. Based on the hormonal changes in KS, there are suggestions that low androgen and higher estrogen levels might be a predisposing factor for the development of autoimmune diseases, but evidence for the association is poor. Epidemiologic studies on larger cohorts of patients are required.

Abstract
Testosterone deficiency has been linked with autoimmune disease and an increase in inflammatory markers, such as C-reactive protein (CRP), tumor necrosis factor, and interleukin-6 (IL-6). However, no large-scale longitudinal studies have examined this association. We examined whether untreated hypogonadism was associated with an increased risk of rheumatic autoimmune disease in a large nationally representative cohort. Using one of the nation's largest commercial insurance databases, we conducted a retrospective cohort study in which we identified 123,460 men diagnosed with hypogonadism between January 1, 2002 and December 31, 2014 and with no prior history of rheumatic autoimmune disease. We matched this cohort to 370,380 men without hypogonadism, at a 1 to 3 ratio, on age and index/diagnosis date. All patients were followed until December 31, 2014 or until they lost insurance coverage or were diagnosed with a rheumatic autoimmune disease. Cox proportional hazards regression was used to calculate adjusted hazard ratios (aHRs). Untreated hypogonadism was associated with an increased risk of developing any rheumatic autoimmune disease (HR = 1.33, 95 % CI = 1.28, 1.38), rheumatoid arthritis (HR = 1.31, 95 % CI = 1.22, 1.44), and lupus (HR = 1.58, 95 % CI = 1.28, 1.94). These findings persisted using latency periods of 1 and 2 years. Hypogonadism was not associated with the control outcome, epilepsy (HR = 1.04, 95 % CI = 0.96, 1.15). Patients diagnosed with hypogonadism who were not treated with testosterone had an increased risk of developing any rheumatic autoimmune disease, rheumatoid arthritis, and lupus. Future research should further examine this association, with particular attention to underlying mechanisms.

Abstract
Oral thrush is considered as the opportunistic infection, which is caused by fungus Candida albicans. Various kinds of immunodeficiency diseases, such as HIV infection, immunosuppressive therapy, use of broad-spectrum antibiotics, and invasive surgical procedures such as solid organ or bone marrow transplantation, lead to increased susceptibility to fungal infections, but persistent and refractory thrush, with typical clinical signs of oral fungal infection and without any other sign of immunodeficiencies, has not been reported so far. We describe a case of persistent and refractory thrush with Klinefelter syndrome (47, XXY) as the unusual cause.

Abstract
Myogenesis, the formation and regeneration of muscular tissue, is a fundamental factor in embryonic development. N-methyl D-aspartate (NMDA) receptor synaptonuclear signaling and neuronal migration factor (Nsmf) mediates NMDA receptor endocytosis in GnRH neuronal cells. NMDA receptor is involved in myoblast differentiation by regulating Ca2 (+) dependent fusion of myocytes. In this study, we investigated the role of Nsmf in myoblast proliferation and differentiation. Quantitative-PCR, immunoblotting, and immunohistochemistry results showed that the Nsmf expression levels increased during both the differentiation and proliferation of myocytes. Knockdown of Nsmf in myocytes by siRNA did not affect the myocyte differentiation marker myogenin. However, flow cytometry showed that the proliferation rate of the Nsmf-knockdown cells was reduced compared to the control cells. Therefore, our results indicate that Nsmf is a novel myogenic factor that can enhance myoblast proliferation. Furthermore, Nsmf may be an important therapeutic target in diseases associated with aging, muscular dystrophy, or cachexia.

Abstract
Clinical and experimental evidence support a role for gonadal steroids in modulating the expression and course of autoimmune diseases such as lupus. Whether or not inherited variation in sensitivity to circulating androgenic hormones could influence the manifestations of such disease is, however, unknown. We sought to determine whether differences in androgen sensitivity conferred by variation in the exon 1 CAG repeat region of the androgen receptor (AR) gene were associated with differences in the clinical or humoral immune manifestations of lupus in a cohort of female subjects. We found that shorter AR CAG repeat lengths in lupus subjects correlated with a higher Systemic Lupus Erythematosus Disease Activity Index score, higher ANA levels, and expression of a broader array of IgG autoantibodies. Our findings of more severe clinical manifestations and more exuberant humoral autoimmunity in women with a shorter AR exon 1 CAG repeat length suggest a role for genetically determined sensitivity to androgens as a modulator of autoimmune processes.

Abstract
Ankylosing spondylitis is a chronic inflammatory disease characterized by inflammatory lower back pain and morning stiffness and accompanied by spine and sacroiliac joint involvement. Klinefelter's syndrome is a genetic condition that only affects males. Affected males have an extra X chromosome. This paper reports a 30-years-old male on followup with the diagnosis of Klinefelters syndrome. The patient admitted with complaints of inflammatory lower back, and neck pain and morning stiffness and was diagnosed with ankylosing spondylitis. Nonsteroidal anti-inflammatory drug and salazopyrine treatment resulted in significant regression in his complaints.

Abstract
As the population ages, more individuals with autoimmune diseases are experiencing reproductive senescence. Understanding the impact of menopause and age-related androgen decline on disease onset and course, as well as the potential for hormonal interventions, is critically important. In men, lupus erythematosis (SLE), rheumatoid arthritis (RA), and multiple sclerosis (MS) are associated with lower androgen levels. However, the impact of age-related declines in testosterone, as well as of testosterone replacement, on disease course remains underexplored. In women, the course of all three diseases with onset after the age of menopause differs from that with onset before menopause. Early age at menopause is associated with increased disease risk, and after menopause, disease course changes in SLE and RA. Less is known about MS. This article summarizes what is known about the relationship between reproductive aging and autoimmune diseases in men and women, and highlights areas for further investigation.

Abstract
Noncompaction of the ventricular myocardium is a congenital cardiomyopathy characterized by prominent ventricular trabeculations and deep intertrabecular recesses. In most cases, noncompaction is an isolated disease confined to the left ventricular myocardium. Fertile eunuch syndrome is a hypogonadotropic hormonal disorder in which the levels of testosterone and follicle-stimulating hormone are low. We report a case of biventricular noncompaction in association with bicuspid aortic valve and severe aortic stenosis in a 42-year-old man who was diagnosed with talipes equinovarus and fertile eunuch syndrome during childhood.

Abstract
We sought to explore whether inherited differences in androgen sensitivity conferred by variation in the length of a CAG repeat in exon 1 of the androgen receptor gene could be correlated with differing manifestations of humoral autoimmunity in men with lupus. In a sample of 15 men with lupus, AR CAG repeat length was linearly correlated with levels of antibodies against extractable nuclear antigens and with the number of diagnostic criteria for lupus. Protein microarrays were used to assess levels of 86 different IgG and IgM autoantibodies in the sera of these patients. IgG autoantibodies were more frequently observed in male lupus patients with longer AR CAG repeat length (>23), while IgM autoantibodies were more prevalent in subjects with shorter CAG repeat length (≤23). These data support a potential role for androgen signaling in the modulation of immunoglobulin class switching processes, with consequent impact on the autoimmune phenotype in men with lupus.

Abstract
The article summarizes reports on the concurrence of Klinefelter's syndrome (KS) with inflammatory rheumatic diseases, rheumatoid arthritis (RA), juvenile idiopathic arthritis, psoriatic arthritis, polymyositis/dermatomyositis, systemic lupus erythematosus, systemic sclerosis, mixed connective tissue disease, the antiphospholipid syndrome, and ankylosing spondylitis. These include two case reports of patients with KS concurrently associated with RA or antisynthetase syndrome, respectively, previously reported by the author and his coworkers. Attention is paid to the pathogenesis and the course of the disease in patients with KS. The importance of early diagnosis of the syndrome, when occurring simultaneously with other diseases of connective tissue, is emphasized.

Abstract
Kilnefelter's syndrome (KFS) tends to be associated with autoimmune diseases. Although several reports describe association of KFS with different autoimmune diseases, association with rheumatoid arthritis is very rare. We report a case of (KFS) who had seropositive erosive rheumatoid arthritis, and discuss the role of sex hormones/X chromosome in the pathogenesis of disease.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that predominantly affects women. Despite isolated reports of patients with coexisting Klinefelter's syndrome (47,XXY) and SLE, no association of Klinefelter's syndrome with SLE or any other autoimmune disease has been established. The present study was undertaken to investigate the prevalence of Klinefelter's syndrome in a large population of patients with SLE. METHODS Sex chromosome genotyping was performed in 981 SLE patients, of whom 213 were men. A first group of 844 SLE patients from 378 multiplex families and a second group of 137 men with nonfamilial SLE were evaluated. In selected cases, chromosomes were enumerated by fluorescence in situ hybridization (FISH) and karyotyping in transformed B cell lines. RESULTS Of 213 men with SLE, 5 had Klinefelter's syndrome (1 in 43). Four of them were heterozygous at X markers, and Klinefelter's syndrome was confirmed by FISH and karyotyping in the fifth. An overall rate of 47,XXY of 235 per 10,000 male SLE patients was found (95% confidence interval 77-539), a dramatic increase over the known prevalence of Klinefelter's syndrome in an unselected population (17 per 10,000 live male births). Asking men with SLE about fertility was highly sensitive (100%) for Klinefelter's syndrome. All 768 women with SLE were heterozygous at X. CONCLUSION The frequency of Klinefelter's syndrome (47,XXY), often subclinical, is increased in men with SLE by approximately 14-fold compared with its prevalence in men without SLE. Diagnostic vigilance for 47,XXY in male patients with SLE is warranted. These data are the first to show an association of Klinefelter's syndrome with an autoimmune disease found predominantly in women. The risk of SLE in men with Klinefelter's syndrome is predicted to be similar to the risk in normal women with 46,XX and approximately 14-fold higher than in men with 46,XY, consistent with the notion that SLE susceptibility is partly explained by an X chromosome gene-dose effect.

Abstract
Testosterone is more than a “male sex hormone”. It is an important contributor to the robust metabolic functioning of multiple bodily systems. The abuse of anabolic steroids by athletes over the years has been one of the major detractors from the investigation and treatment of clinical states that could be caused by or related to male hypogonadism. The unwarranted fear that testosterone therapy would induce prostate cancer has also deterred physicians form pursuing more aggressively the possibility of hypogonadism in symptomatic male patients. In addition to these two mythologies, many physicians believe that testosterone is bad for the male heart. The classical anabolic agents, 17-alkylated steroids, are, indeed, potentially harmful to the liver, to insulin action to lipid metabolism. These substances, however, are not testosterone, which has none of these adverse effects. The current evidence, in fact, strongly suggests that testosterone may be cardioprotective. There is virtually no evidence to implicate testosterone as a cause of prostate cancer. It may exacerbate an existing prostate cancer, although the evidence is flimsy, but it does not likely cause the cancer in the first place. Testosterone has stimulatory effects on bones, muscles, erythropoietin, libido, mood and cognition centres in the brain, penile erection. It is reduced in metabolic syndrome and diabetes and therapy with testosterone in these conditions may provide amelioration by lowering LDL cholesterol, blood sugar, glycated hemoglobin and insulin resistance. The best measure is bio-available testosterone which is the fraction of testosterone not bound to sex hormone binding globulin. Several forms of testosterone administration are available making compliance much less of an issue with testosterone replacement therapy.

Abstract
OBJECTIVE Ankylosing spondylitis and related spondylarthritides are associated with HLA-B27, and also with intestinal inflammation, by unknown mechanisms. The folded HLA-B27 molecule is a trimer of heavy chain, beta2-microglobulin (beta2m), and short peptide. However, B27 heavy chain has an unusual propensity to misfold and trigger the unfolded protein response (UPR). This study was initiated to test the hypothesis that B27 misfolding plays a role in the pathogenesis of spondylarthritis. METHODS Rats with high transgene copy numbers of HLA-B27 heavy chain together with human beta2m (Hubeta2m) spontaneously develop colitis, peripheral arthritis, and occasional spondylitis, and those with lower transgene copy numbers remain healthy. We crossed disease-prone and healthy HLA-B27/Hubeta2m-transgenic rat lines with a healthy line, 283-2, carrying only the Hubeta2m transgene. HLA-B27 assembly was assessed by pulse-chase analysis of B27 molecules, and UPR triggering was assessed by measuring BiP/Grp78 messenger RNA (mRNA) in splenic concanavalin A blasts. Surface expression of B27 and Hubeta2m was determined by flow cytometry. Disease manifestations were identified by clinical observation, histology, and measurement of cytokine mRNA. RESULTS The extra Hubeta2m from the 283-2 line significantly reduced B27 misfolding and UPR triggering. Unexpectedly, however, F1 male offspring of the healthy 21-3 line crossed with the 283-2 line showed a high prevalence, severity, and duration of arthritis and spondylitis, in the absence of colitis. The arthropathy showed many features characteristic of human spondylarthritis. CONCLUSION These results suggest that B27 misfolding is associated with intestinal inflammation, but that neither B27 misfolding nor intestinal inflammation is critical to the development of B27-associated arthropathy.

Abstract
Current concepts of neuroendocrine immune (NEI) aspects of rheumatoid arthritis (RA) are reviewed and recent clinical trials of glucocorticoids and sex steroids are summarized. A novel physiopathogenetic perspective is presented. Data are provided of amplified NEI interactions and dysregulation, many years before symptomatic onset of RA. Chronic imbalances between the NEI, vascular endothelial, neural, and other vital counterregulatory intertwined networks are proposed to cause RA and influence its disease activity. Future research may reveal means of diminishing the onset risk as well as disease activity of RA by controlling these imbalances of NEI and other vital networks.

Abstract
Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease that is caused by genetic and environmental factors. The tumour necrosis factor (TNF) superfamily of genes play a central role in immune regulation and have been proposed to be involved in the development of SLE. TNFRSF5 (CD40) falls on 20q11-13, a region linked with SLE in three independent genome-wide studies. TNFSF5 (CD40L) falls on Xq26 and is the ligand for TNFRSF5. Seven single-nucleotide polymorphisms (SNPs) in CD40 and eight SNPs in CD40L were looked at for linkage disequilibrium (LD) and haplotype analysis in European-Caucasians. Limited haplotype diversity was observed across CD40 and CD40L, and >97% of the diversity was captured. We also examined the association of SNPs and haplotypes in CD40 and CD40L with SLE in European-Caucasians. There was no evidence of association for CD40 or CD40L in 408 European-Caucasian families with SLE from UK. Haplotype tagging SNPs (htSNPs) are made known, which will facilitate analysis for susceptibility in other autoimmune diseases and risk for infectious disease.

Abstract
A 54-year-old man of Persian origin presented to our department with a 1-year history of ulcers on the right leg that had been unresponsive to numerous topical treatments, accompanied by lymphedema of the right leg. Medical history included hypergonadotropic hypogonadism, which had not been further investigated. He was treated for 20 years with testosterone IM once monthly, which he stopped a year before the current hospitalization for unclear reasons. The patient reported no congenital lymphedema. Physical examination revealed two deep skin ulcers (Figure 1) on the right leg measuring 10 cm in diameter with raised irregular inflammatory borders and a boggy, necrotic base discharging a purulent hemorrhagic exudate. Bilateral leg pitting edema and right lymphangitis with lymphadenitis were noted. He had low head hair implantment, sparse hair on the body and head, hyperpigmentation on both legs, onychodystrophia of the toenails (mainly the large toe and less prominent on the other toes), which was atrophic lichen-planus-like in appearance and needed no trimming (Figure 2), normal hand nails, oral thrush, and angular cheilitis. Other physical findings were gynecomastia, pectus excavatum, small and firm testicles, long extremities, asymmetrical goiter, systolic murmur 2/6 in left sternal border, and slow and inappropriate behavior. The patient's temperature on admission was 39 degrees C. Blood cultures were negative for bacterial growth. Results of laboratory investigations included hemoglobin (11.2 g/dL), hematocrit (26.8%), normal mean corpuscular volume and mean corpuscular hemoglobin volume, and red blood cell distribution width (16%). Blood smear showed spherocytes, slight hypochromia, anisocytosis, macrocytosis, and microcytosis. Blood chemistry values were taken for iron (4 micro g/dL [normal range 40-150 micro g/dL]), transferrin (193 mg/dL [normal range 220-400 mg/dL]), ferritin (1128 ng/mL [normal range 14-160 ng/mL]), transferrin saturation (1.5% [normal range 20%-55%]), serum folate (within normal limits), and vitamin B12 (within normal limits). Direct Coombs' test equaled positive 2 + IgG. All these values indicated anemia of chronic diseases combined with hemolytic anemia. Further blood work-up tested antinuclear antibody (positive <1:80 homogeneous pattern), rheumatoid factors (143 IU/mL [positive >8.5 IU/mL]), C-reactive protein (286 mg/L [normal range 0-5 mg/L]), anticardiolipin IgM antibody (9.0 monophosphoryl lipid U/mL [normal range 0-7.00 MPL U/mL]) and antithrombin III activity (135% [normal range 74%-114%]). Results of other blood tests were within normal limits or negative, including lupus anticoagulant, beta2 glycoprotein, anticardiolipin IgG Ab, anti-ss DNA Ab, C3, C4, anti-RO, anti-LA, anti-SC-70, anti-SM Ab, P-ANCA, C-ANCA, TSH, FT4, anti-T microsomal, antithyroglobulin, protein C activity, protein S free, cryoglobulins, serum immunoelectrophoresis, VDRL, hepatitis C antibodies, hepatitis B antigen, and human immunodeficiency virus. Endocrinological work-up examined luteinizing hormone (22.9 mIU/mL [normal range for adult men 0.8-6 mIU/mL]), follicle stimulating hormone (49.7 mIU/mL [normal range for adult men 1-11 mIU/mL]), testosterone (0.24 ng/mL [normal range for adult men 2.5-8.0 ng/mL]), bioavailable testosterone (0.02 ng/mL [normal range for adult men >0.6 ng/mL]), and percent bioavailable test (8.1% [normal value >20%]). These results indicate hypergonadotropic hypogonadism. Plasminogen activator inhibitor 1 was 6 U (normal value 5-20 U/mL). Karyotyping performed by G-banding technique revealed a 47 XXY karyotype, which is diagnostic of Klinefelter's syndrome. Doppler ultrasound of the leg ulcers disclosed partial thrombus in the distal right femoral vein. X-rays and bone scan displayed osteomyelitis along the right tibia. Histological examination of a 4-mm punch biopsy from the ulcer border revealed hyperkeratosis, acanthosis, hypergranulosis, and mixed inflammatory infiltrate containing eosinophils compatible with chronic ulcer. Multiple vessels were seen, compatible with a healing process. Direct immunofluorescence of the biopsy revealed granular IgM in the dermo-epidermal junction. Indirect immunofluorescence was negative. Thyroid function tests showed normal thyroid stimulating hormone and free throxine4. Multinodular goiter was seen on thyroid scan and ultrasound. Thyroid fine needle aspiration was compatible with multinodular goiter (normal follicular cells, free colloid, macrophages with pigment). IV treatment with amoxicillin-clavulanic acid 1 g t.i.d. was administered for 2 weeks, with a decrease in temperature and normalization of the leukocyte level. Oral antibiotic treatment with amoxicillin-clavulanic acid was continued for 10 more days, followed by 25 days of ciprofloxacin for the osteomyelitis. Local treatment included saline soakings followed by application of Promogran (Johnson & Johnson, New Brunswick, NJ) and Kaltostat (ConvaTec Ltd., a Bristol-Myers Squibb Company, New York, NY) with slight improvement. At the same time, the patient was treated with warfarin sodium due to deep vein thrombosis under international normalized ratio 2-3. The patient was treated with IM testosterone once monthly for 1 year, which resulted in a reduction in the diameter and depth of the leg ulcers (Figure 3). Blood tests were not performed for follow-up of the immune state.

Abstract
Gender and sex hormones are strongly related to the incidence and progression of autoimmune rheumatic diseases. Although sex steroids have been shown to have direct effects on the immune system, their influence in vivo may be mediated via interactions with third party systems including the hypothalamic-pituitary-adrenal axis. Such interactions are well demonstrated in experimental animals. In humans, there is increasing, although indirect, evidence that these interactions also occur. Possible interactions at the cell and gene level, with mutual antagonism or synergy between cortico- and gonadal steroids, open new exciting hypotheses that await clarification.
