Background:Fertility is thought to be not reduced in women affected by systemic lupus erythematosus (SLE), however disease-related factors, psychosocial effects of chronic disease as well as medication exposure might impair gonadal function.Objectives:The aim of this systematic review was to explore clinical, hormonal, serological, instrumental and management factors associated with fertility outcomes in women of childbearing age with SLE.Methods:This systematic review was conducted following the Preferred Reporting Items for systematic reviews and Meta-analysis (PRISMA) statement. All articles available in English, published from 1972 to 15th August 2020 in Pubmed, EMBASE, Scopus and Cochrane Library. Study selection and data collection were performed by two independent reviewers. All data were extracted using a standardized template. Risk of bias of the included studies was assessed by using the NIH risk-of-bias tool [1].Results:Of 788 abstracts, we included in the review 45 studies of which 1 systematic literature reviews, 16 cross-sectional studies, 15 cohort studies, 12 observational studies and 1 case-series study, with a total of 4656 patients. The mean age was 33.5 ± 5.4 years, while the mean disease duration was 97.4 ± 65.2 months. Figure 1 illustrates the quality of the included studies. Definitions of fertility/premature ovarian failure (POF) adopted in the studies varied in terms of the number of months of amenorrhea considered. Most studies did not use a hormonally based definition of fertility. Clinical factors associated with the development of POF were older age at the time initiation of therapy and older age at the onset of SLE disease. Cyclophosphamide exposure (CYC) and its cumulative dose influenced gonadal function in SLE women, leading to amenorrhoea and ovarian failure, as reported in 19 studies. Mycophenolate, azathioprine, calcineurin inhibitors and steroids seem to be associated with a lower risk of ovarian failure compared to CYC. 3 studies demonstrated that POF was more frequent in patients treated with CYC not receiving gonadotropin-releasing hormone analogues (GnRH) in comparison to those co-treated with GnRH. 11 studies evaluated the impact of damage and disease activity on ovarian reserve in patients with SLE with conflicting evidence. Finally, 18 studies investigated exposure to hormonal and serological factors able to influence fertility outcomes; among others nor Anti-Müllerian Hormone, neither anti-corpus luteum antibodies were associated with POF.Conclusion:The role of disease activity on fertility in SLE patients is contradictory. Regarding management factors associated with fertility in SLE women of childbearing age, the strongest evidence is about the treatment with CYC and its cumulative dose. Hormonal and serological factors did not impact on fertility outcome but might be used as a surrogate of fertility, especially after treatment with disease-specific drugs.References:[1]Study Quality Assessment Tools NIH. https://www.nhlbi.nih.gov/health-topics/study-quality-assessment-tools.[2]Andreoli L. et al.

Abstract Background and Aims With continuous identification of post-translational modified isoforms of proteins, it is becoming increasingly clear that post-translational modifications limit or modify the biological functions of native proteins are majorly involved in development of various chronic disease. This is mostly due to technically advanced molecular identification and quantification methods, mainly based on mass spectrometry. Mass spectrometry has become one of the most powerful tools for the identification of lipids. Method In this study, we used sophisticated high-resolution mass-spectrometric methods to analyze the soluble ligand of receptor Notch-3, namely the Y-box protein (YB)-1, in serum from systemic lupus erythematosus (SLE) patients. In addition, kidneys of lupus-prone (MRL.lpr) mice were analyzed by mass-spectrometric imaging techniques to identify the underlying pathomechanisms. Serum YB-1 was isolated by chromatographic methods, afterwards digested by trypsin and analyzed by matrix assisted laser desorption/ionization mass spectrometry (MALDI-MS). The kidneys were fixed in paraffin, then kidney sections were deparaffinized, tryptic digested and analyzed by mass-spectrometric imaging techniques. Mass-spectrometry of extracellular YB-1 in SLE patient serum revealed post-translational guanidinylation of two lysine’s within the highly conserved cold shock domain (CSD) of the YB-1 protein (YB-1-2G). Patients with increased disease activity and those with active renal involvement (lupus nephritis, LN) had a higher degree of dual-guanidinylation within the CSD. Of note, at least one of these modifications was present in all analyzed LN patients, whereas single-guanidinylated YB-1 was present in only one and double modification in none of the control individuals. Mass-spectrometric imaging analyses specifically localized YB-1-2G and increases Notch-3 expression in kidney sections from MRL.lpr mice. Results The data from this study clearly demonstrate the high potential of high-resolution mass spectrometric methods as well as mass spectrometric imaging techniques to identify pathomechanisms of diseases like SLE/LN.

Ophthalmic Manifestations

Objective Ophthalmic complications in Systemic Lupus Erythematosus (SLE) are broad and can occur in up to a third of patients. The British Isles Lupus Assessment Group (BILAG) 2004 Index identifies 13 ocular manifestations of active SLE, as opposed to those related to previous disease activity and/or the consequences of therapy. We conducted a systematic review of published literature to determine the frequency of ophthalmic manifestations of active SLE. Methods A systematic literature search of Ovid MEDLINE and EMBASE from their respective inceptions to July 2020 was conducted to identify cohort, case–control and cross-sectional studies. Results 22 studies meeting eligibility criteria were included. Most studies featured small sample sizes and were judged to have a high risk of methodological bias. The number and quality of studies did not allow us to confidently estimate the incidence of the conditions. No studies reported epidemiological data for orbital inflammation/myositis/proptosis. The prevalence of each of the other ocular manifestations, with the exception of retinal vaso-occlusive disease, was consistently less than 5%. Retinal vasculitis, uveitis and isolated cotton wool spots tended to be associated with more active SLE disease. Conclusion The prevalence of eye disease due to SLE activity is uncommon, but clinicians should be aware that some conditions tend to be associated with more active systemic disease. Further studies to determine the incidence and risk factors for these ophthalmic manifestations are needed.
