Objectives Cognitive dysfunction (CD) is a common manifestation of SLE that can have detrimental consequences for those affected. To date, no treatments have been approved for SLE-CD. This study aims to assess the association of azathioprine (AZA) and mycophenolate (MMF) use with SLE-CD, given that these medications have demonstrated neuroprotective qualities in prior studies. Methods Consecutive adult SLE patients presenting to a single healthcare center were considered for participation. The ACR neuropsychological battery for SLE was administered to consenting patients at 0, 6 and 12 months. Scores were compared with age- and sex-matched controls. Primary outcome was CD, defined as a z-score ≤−1.5 in two or more cognitive domains. Mixed-effects logistic regression models were constructed to estimate the odds of CD with respect to AZA and MMF use. Results A total of 300 participants representing 676 patient visits completed the study; 114 (38%) met criteria for CD at baseline. The cumulative AZA dose (g/kg) was associated with reduced odds of CD [odds ratio (OR) 0.76 (95% CI 0.58, 0.98), P = 0.04]. Years of AZA treatment was also associated with reduced odds of CD [OR 0.72 (95% CI 0.54, 0.97), P = 0.03]. MMF use was not associated with CD. Conclusion AZA use was associated with significantly lower odds of SLE-CD, while MMF use was not. Additional studies are warranted to further investigate the relationship of AZA and SLE-CD.

Antiphospholipid syndrome (APS) is a systemic autoimmune disorder marked by thrombosis and/or pregnancy morbidity in the presence of antiphospholipid antibodies (aPL). At the present time, treatment is primarily focused on anticoagulation. However, there is increasing awareness of the mechanisms involved in APS pathogenesis, which has led to the trial of novel therapies targeting those mechanisms. Following a brief review of the etiopathogenesis of and current management strategies in APS, this paper focuses on the evidence for these potential, targeted APS treatments, e.g., hydroxychloroquine, statins, rituximab, belimumab, eculizumab, defibrotide, sirolimus, and peptide therapy.

BackgroundSLE manifestations after ESRD may be underdiagnosed and undertreated, contributing to increased morbidity and mortality. Whether specific symptoms persist after ESRD or a shift towards new manifestations occurs has not been extensively studied, especially in the non-Caucasian patients in the United States. In addition, hydroxychloroquine (HCQ) prescribing patterns post-ESRD have not been described. The objective of this study was to assess lupus activity and HCQ prescribing before and after ESRD development. Knowledge gained from this study may aid in the identification of SLE manifestations and improve medication management post-ESRD.MethodsWe performed a retrospective cohort study of SLE patients with incident ESRD between 2010 and 2017. SLE-related symptoms, serologic markers of disease activity, and medication use were collected from medical records before and after ESRD development.ResultsFifty-nine patients were included in the study. Twenty-five (43%) patients had at least one clinical (non-renal) SLE manifestation documented within 12 months before ESRD. Of them, 11/25 (44%) continued to experience lupus symptoms post-ESRD; 9 patients without clinical or serological activity pre-ESRD developed new symptoms of active SLE. At the last documented visit post-ESRD, 42/59 (71%) patients had one or more clinical or serological markers of lupus activity; only 17/59 (29%) patients achieved clinical and serological remission.Thirty-three of 59 (56%) patients had an active HCQ prescription at the time of ESRD. Twenty-six of the 42 (62%) patients with active SLE manifestations post-ESRD were on HCQ. Patients who continued HCQ post-ESRD were more likely to be followed by a rheumatologist (26 [87%] vs 17 [61%],p = 0.024), had a higher frequency of documented arthritis (10 [32%] vs 1 [4%],p = 0.005), CNS manifestations (6 [20%] vs 1 [4%],p = 0.055), and concurrent immunosuppressive medication use (22 [71%] vs 12 [43%],p = 0.029).ConclusionsLupus activity may persist after the development of ESRD. New onset arthritis, lupus-related rash, CNS manifestations, low complement and elevated anti-dsDNA may develop. HCQ may be underutilized in patients with evidence of active disease pre- and post ESRD. Careful clinical and serological monitoring for signs of active disease and frequent rheumatology follow up is advised in SLE patients both, pre and post-ESRD.

It is commonly assumed that cognitive function deteriorates with age. While some age-related changes in cognitive function exist, they do not exist to the extent that is widely believed. The pathologic changes seen in patients with dementia differ significantly from those seen in healthy elderly persons. Additionally, many seniors exhibit virtually no changes at all and continue to lead fruitful lives well beyond the average life expectancy. There are important implications of assuming that dementia is a normal part of aging: this myth contributes to poorer cognitive performance in seniors, to stigma and to a lack of initiative in preventing cognitive decline. Here the author demonstrates the prevalence of this myth and then challenges it, taking into account current evidence regarding normal age-related cognitive changes and pathologic cognitive changes as seen in patients with dementia.
