BACKGROUND
Systemic Lupus Erythematosus (SLE) is an autoimmune inflammatory condition affecting multiple systems. Cardiovascular morbidity is a significant concern, with around 25% of SLE patients experiencing cardiac complications.
OBJECTIVE
This study aims to determine the prevalence of cardiovascular morbidity in SLE patients in King Fahad Medical City (KFMC) in Riyadh, Saudi Arabia.
METHODOLOGY
This retrospective record-based research was conducted at KFMC from January 2015 to October 2023. A review of the medical files of all SLE patients was accomplished.
RESULTS
The vast majority of the patients (90.9%) were females. The mean age for the patients was 36.5 years. The most common comorbidities were lupus nephritis (34.6%), hypothyroidism (18.4%), and anti-phospholipid syndrome (9.2%). The most commonly used medications were hydroxychloroquine (81.8%), corticosteroids (prednisolone) (43.0%), and mycophenolate mofetil (27.9%). Around 45.2% (n= 176) of the patients with SLE developed cardiovascular complications. The most commonly reported cardiovascular diseases that developed after diagnosing patients with SLE were hypertension (22.4%), valvular heart diseases (13.2%), and dyslipidemia (9.2%). The study also found that anti-dsDNA antibodies can reduce the likelihood of developing hypertension by 40%. This research contributes to the medical literature on SLE and sets the stage for future research on personalized healthcare strategies for managing SLE and its complications.
CONCLUSION
This study highlights that a considerable proportion of SLE patients(~50%) develop cardiovascular complications, with hypertension, valvular heart diseases, and dyslipidemia being the most common. We also discovered that anti-double-stranded deoxyribonucleic acid antibodies (Anti-dsDNA) reduce the likelihood of developing hypertension.

Review
Antiphospholipid antibodies (aPL) are both laboratory evidence and causative factors for a broad spectrum of clinical manifestations of antiphospholipid syndrome (APS), with thrombotic and obstetric events being the most prevalent. Despite the aPL-triggered vasculopathy nature of APS, vasculitic-like manifestations rarely exist in APS and mainly appear associated with other concurrent connective tissue diseases like systemic lupus erythematous. Several studies have characterized pulmonary capillaritis related to pathogenic aPL, suggesting vasculitis as a potential associated non-thrombotic manifestation. Here, we describe a 15-year-old girl who develops hepatic infarction in the presence of highly positive aPL, temporally related to prior non-severe COVID-19 infection. aPL-related hepatic vasculitis, which has not been reported before, contributes to liver ischemic necrosis. Immunosuppression therapy brings about favorable outcomes. Our case together with retrieved literature provides supportive evidence for aPL-related vasculitis, extending the spectrum of vascular changes raised by pathogenic aPL. Differentiation between thrombotic and vasculitic forms of vascular lesions is essential for appropriate therapeutic decision to include additional immunosuppression therapy. We also perform a systematic review to characterize the prevalence and clinical features of new-onset APS and APS relapses after COVID-19 for the first time, indicating the pathogenicity of aPL in a subset of COVID-19 patients.

INTRODUCTION
Since the beginning of the pandemic, many skin manifestations associated with COVID-19 have been reported. New reports show that COVID-19 can lead to autoimmune diseases (AIDs) and autoinflammatory diseases, especially dermatological.
METHODS
A prospective study was conducted by the dermatology department of the Centre Hospitalier Universitaire Ibn Rochd (CHU Ibn Rochd) of Casablanca in Morocco since the beginning of the pandemic including 18 patients with COVID-19-related skin manifestations.
RESULTS
Eighteen cases were collected with confirmed SARS-CoV-2 infection. The mean COVID score was 0.7. A percentage (94.44%) of the cases had general symptoms. Skin involvement was variable, mainly maculopapular rash (44.44%), purpura (27.77%), urticaria, varicelliform rash, necrotic lesions of the face, and pityriasis rosea Gibert (PRG)-like lesions. Mucosal involvement was found in 50%. Viral reactivation was found in 5.55%. Telogen effluvium was found in 22.22%. Moreover, AID was triggered by COVID-19: lupus (11.11%), associated with antiphospholipid syndrome (APL Sd) (5.55%), psoriasis (11.11%), alopecia, and pemphigus. Severe toxidermia was potentiated by SARS-CoV-2 infection (22.22%): Stevens-Johnson syndrome (Sd), acute generalized exanthematous pustulosis (APEG), and drug reaction with eosinophilia and systemic symptoms (DRESS).
CONCLUSION
The interest of this work is to report our experience during the COVID-19 pandemic to understand some pathophysiological mechanisms of its dermatological manifestations and to draw the attention of clinicians to the link of this infection with autoimmune and autoinflammatory diseases and toxidermia.

We report a case wherein adrenal function remained preserved despite bilateral adrenal infarction, as evidenced by dual-energy computed tomography (DECT) iodine density images. The patient was a 37-year-old man with a history of antiphospholipid syndrome concomitant with systemic lupus erythematosus. The patient underwent contrast-enhanced DECT, which revealed bilateral adrenal infarction. Laboratory tests revealed preserved adrenal function. On the iodine density images, the infarcted and noninfarcted areas in the adrenal glands were visually different. The volume of the non-infarcted area was 8.9 mL, which was 41% of the total adrenal volume. DECT may be a useful complementary tool for assessing the preservation of adrenal function.

Antiphospholipid syndrome (APS) is characterized by thrombosis (which may be venous, arterial, or microvascular) and/or pregnancy morbidity in association with persistently positive antiphospholipid antibodies. Although thrombosis and pregnancy morbidity are the main clinical criteria for a diagnosis of APS in the revised Sapporo (Sydney) criteria, recently published American College of Rheumatology/European Alliance of Associations for Rheumatology classification criteria for APS have significantly refined the diagnostic algorithm to include a scoring system clustered into 6 clinical domains (macrovascular venous thromboembolism, macrovascular arterial thrombosis, microvascular thrombosis, obstetric, cardiac valve, and hematologic). Diagnosis of APS is complicated by the fact that significant heterogeneity exists in patients' clinical presentation, underlying vascular risk factors, and methods of detecting antiphospholipid antibodies. Despite the autoimmune nature of APS, anticoagulation remains the main strategy for secondary prevention of thrombosis. Furthermore, optimal antithrombotic treatment in APS patients with arterial thrombosis remains controversial due to a paucity of data from randomized controlled studies. In this paper, we present 2 cases and highlight the diagnostic and therapeutic challenges they pose and how we approach them in the light of current evidence.

We investigated trends in the use of therapeutic drugs for pregnant patients with rheumatic diseases in nine Chinese cities (Beijing, Chengdu, Guangzhou, Harbin, Hangzhou, Shanghai, Shenyang, Tianjin, and Zhengzhou) to provide a reference for drug use in clinic. Outpatient prescription data for pregnant patients diagnosed with rheumatic diseases in nine cities across China in 2016-2021 were extracted from the Hospital Prescription Cooperation Project of the Hospital Pharmacy Professional Committee of the Chinese Pharmaceutical Association. A retrospective analysis was then performed, incorporating data on patient age, defined daily doses (DDDs), defined daily cost (DDC), and other metrics. In 2016-2020, more than 70% of the pregnant patients diagnosed with rheumatic diseases in these nine cities were 25 to < 35 years of age. The most common rheumatic diseases during pregnancy were antiphospholipid antibody syndrome (APS) and systemic lupus erythematosus (SLE). In terms of the routine use of daily therapeutic drugs, the DDDs of low molecular weight heparins (LMWHs), glucocorticoids, and immunosuppressive agents dominated the top three. Intravenous immunoglobulin (IVIG) and tumor necrosis factor inhibitors (TNFi) have been used since 2019 and had been in the forefront of the DDC. The number and total cost of prescriptions for therapeutic drugs of pregnancy complicated by rheumatic diseases, have increased significantly over the study interval. Conventional therapeutic drugs, especially glucocorticoids, LMWHs, and hydroxychloroquine were the most widely used drugs in pregnant patients with rheumatic diseases. However, IVIG and TNFi, relatively high cost, have shown gradual increases in clinical use since 2019.

Review
BACKGROUND
The optimal treatment regimen for patients with Hughes syndrome remains unclear. Therefore, the authors sought to compare the outcomes of warfarin vs. factor Xa inhibitors in patients with Hughes syndrome.
METHODS
MEDLINE, Embase, and Cochrane Central databases were searched for randomized controlled trials (RCTs) comparing 8 efficacy and safety of warfarin and factor Xa inhibitors in patients with Hughes syndrome. Recurrent thrombosis, all-cause mortality, stroke, adverse reactions, and bleeding were among 10 outcomes of interest. Mantel-Haenszel weighted random-effects model was used to calculate 11 relative risks (RRs) with 95% CIs.
RESULTS
The analysis included 625 patients from four RCTs and one post-hoc analysis. Meta-analysis showed a statistically non-significant difference between factor Xa inhibitors and warfarin in the recurrent thrombosis risk (arterial or venous) [RR 2.77 (95%, CI 0.79, 9.65); =0.11, I=50%]. Consistent results were revealed among patients with a previous history of arterial thrombosis [RR 2.76 (95% CI 0.93, 8.16); =0.75, I=0%], venous thrombosis [RR 1.71 (95% CI 0.60, 4.84); =0.31, I=15%] and patients who were triple antiphospholipid antibodies (aPL) positive [RR 4.12 (95% CI 0.46, 37.10); 21 =0.21, I=58%]. Factor Xa inhibitors were significantly associated with an increased risk of stroke [RR 8.51 (95% CI 2.35, 13.82); =0.47, I=0%].
CONCLUSION
Factor Xa inhibitors exhibited an increased risk of stroke among patients with Hughes syndrome. In addition, although not significant, the higher RRs among patients on factor Xa inhibitors may indicate a higher risk of thrombotic events associated with factor Xa inhibitors.

Review
In the recently updated German S2k Guideline "Diagnostics and Therapy of Venous Thrombosis and Pulmonary Embolism," a new chapter was incorporated about recurrent venous thromboembolism (VTE) in patients on anticoagulation treatment. Despite the high efficacy of anticoagulation in most patients, approximately 2% experience a recurrent VTE event while receiving anticoagulant drugs. The proper diagnosis of the recurrent VTE is important and possible only with the knowledge of localization and thrombus burden of the primary VTE event. Possible reasons for recurrent VTE events in patients on anticoagulation are non-adherence to medication, sub-therapeutic drug levels due to resorption disorders or drug interactions, or concomitant disease with high thrombogenicity. Cancer is the most common underlying disease, but it is important to investigate and understand possible other causes whenever a breakthrough VTE event occurs. This results in the recommendation that in patients with VTE recurrence on therapeutic anticoagulation, in particular, the presence of malignant disease, antiphospholipid syndrome, and rare diseases like paroxysmal nocturnal hemoglobinuria or Behçet's disease should be considered. For VTE recurrence during heparin therapy, heparin-induced thrombocytopenia type II needs to be ruled out, even if platelet counts are within the normal range. Although the mechanisms of recurrence on anticoagulation can be evaluated in a certain degree, clinical evidence for the management of recurrent VTE in anticoagulated patients is minimal and mainly based on expert opinion. Switching anticoagulant medication and intensifying anticoagulant treatment are possible options.
