Cardiovascular (CV) disease is the leading cause of mortality in systemic lupus erythematosus (SLE). The risk of myocardial infarction (MI) in SLE is twice the incidence and ten years earlier in onset than in the general population. We present the first known case in the Philippines of acute MI from triple vessel coronary artery disease (CAD) in a young female patient with SLE. This aims to increase recognition and improve preventive strategies for this rare lupus complication. A 31-year-old female with SLE for thirteen years, antiphopspholipid syndrome (APS) and controlled hypertension (HTN) presented with acute chest pain, diaphoresis, and dyspnea. She was a non-smoker with quiescent lupus and nephritis, maintained on low-dose aspirin, mycophenolate mofetil and hydroxychloroquine for the past four years. The physical examination revealed hypertension, bradycardia, normal heart sounds without murmurs, and no signs of lupus flare. The troponin level was elevated, and the electrocardiogram showed inferior wall ST-segment elevation myocardial infarction (STEMI). Coronary angiography revealed triple-vessel disease, with 80-90% stenosis of the left circumflex artery, and total occlusion of the left anterior descending and right coronary artery. There were segmental wall motion abnormalities and a low ejection fraction of 44% on echocardiography. The complete blood count, urinalysis, and serum C3 were within normal range. The anti-dsDNA was low and lipid levels were abnormal. The patient refused coronary artery bypass grafting (CABG). Medical management consisting of anti-platelets, beta-blockers, statin, and warfarin was maximized. The patient completed one year of follow-up without any lupus flares or cardiovascular events. This case illustrates the complex interaction of disease-related and traditional cardiovascular risk factors leading to premature coronary artery disease in a young female with SLE. The case demonstrates favorable one-year outcomes after optimized post-MI medical management. Aside from optimized lupus control and reduced glucocorticoid use, proactive screening and aggressive management of modifiable CV risk factors and antiphospholipid antibodies (aPL), are necessary.

Abstract An 18-year-old female with Systemic Lupus Erythematosus (SLE) presented with bilateral thigh pain, fever, and diarrhea three days before admission. Diagnosed with SLE one month earlier, she reported prior symptoms, including joint pain, malar rash, hair loss, and hyperpigmented lesions. Initial investigations revealed elevated transaminase levels (AST 355, ALT 132), positive ANA, decreased complement levels (C3 68, C4 16.8), and raised creatine kinase (619). A muscle biopsy confirmed myositis. The patient was treated with immunosuppressant (a combination of steroids and hydroxychloroquine) and supportive therapy. By the eighth day of hospitalization, her symptoms, especially thigh pain, resolved. Electromyocardiography was done, and the results were normal, indicating therapeutic success. This case highlights the importance of prompt diagnosis and management of myositis as a rare SLE manifestation to achieve favorable outcomes.

OBJECTIVES: To investigate the causal associations between autoimmune diseases and aplastic anemia (AA) using Mendelian randomization analysis. METHODS: Publicly available genome-wide association study (GWAS) data were utilized to obtain single nucleotide polymorphisms (SNPs) associated with autoimmune diseases and AA for analysis. The inverse variance weighted (IVW) method was employed as the primary analytical approach, with MR Egger, Weighted Mode, Weighted Median, and Simple Mode methods serving as complementary analyses. Heterogeneity and pleiotropy analyses were conducted using designated functions, and the robustness of Mendelian randomization results was assessed using leave-one-out analysis. RESULTS: The two-sample Mendelian randomization analysis using the IVW method revealed significant positive causal associations of rheumatoid arthritis (OR=1.094, 95% CI: 1.023-1.170, P=0.009, adjusted P=0.042), systemic lupus erythematosus (OR=1.111, 95% CI: 1.021-1.208, P=0.015, adjusted P=0.036), Hashimoto thyroiditis (OR=1.206, 95% CI: 1.049-1.387, P=0.009, adjusted P=0.029), and Sicca syndrome (OR=1.173, 95% CI: 1.054-1.306, P=0.004, adjusted P=0.035) with AA, which was supported by the results from the Weighted Median method. Sensitivity analyses indicated no evidence of pleiotropy or heterogeneity, and leave-one-out analysis confirmed the robustness of the causal relationships. No direct evidence was found linking Graves' disease, ulcerative colitis, Crohn's disease, autoimmune hepatitis, primary biliary cholangitis, or primary sclerosing cholangitis with AA (P>0.05, adjusted P>0.05), indicating a lack of causal association. Reverse Mendelian randomization results and multiple corrections indicated that AA was not an influencing factor for autoimmune diseases (adjusted P>0.05). CONCLUSIONS Our findings support at the genetic level that rheumatoid arthritis, systemic lupus erythematosus, Hashimoto thyroiditis, and Sicca syndrome are risk factors for AA, and confirm a causal association of the these 4 autoimmune diseases with an increased risk of AA.

Overlap syndrome is a rare condition involving the coexistence of at least two distinct autoimmune diseases, such as systemic lupus erythematosus and systemic sclerosis. This condition has limited studies on epidemiology probably because it is often under-recognized. We present a 22-year-old Filipino female with a 10-month history of hyperpigmented patches on the malar surface and extremities, with associated photosensitivity, fatigue, pallor, arthralgia, and oral ulcers, and positive antinuclear antibody titer. She was treated with oral Prednisone in tapering doses, leading to clinical improvement. Eight months later, there was a recurrence of hyperpigmented patches on the face and extremities with skin tightening and diffuse hair loss, development of shiny skin with facial fold loss, a beak-like nasal appearance, and episodes of dyspnea and malaise. Consistent with scleroderma, the patient was started on mycophenolate mofetil (MMF) 500 mg daily, with close monitoring for disease progression and systemic involvement. Overlap syndrome remains under-recognized due to its variable presentation and rarity. Treatment is individualized based on the specific connective tissue diseases involved and the patient’s symptoms. Multidisciplinary care is crucial for timely management and to adjust treatment as needed, given the potential for life-threatening complications involving cutaneous and internal organs.

A 26-year-old Filipino woman, gravida 4 para 0 (G4P0), with systemic lupus erythematosus (SLE) and lupus nephritis (LN), presented at 7 weeks of gestation. Her history included three previous pregnancy losses, including a stillbirth due to eclampsia. Following pregnancy confirmation, medications were adjusted to pregnancy-compatible immunosuppressants and antihypertensives. At 13 weeks, her disease remained quiescent, with persistent proteinuria and stable platelets. The patient remains under outpatient surveillance with plans for referral to tertiary maternal-fetal medicine (MFM) care. This case illustrates management challenges in lupus nephritis during pregnancy, emphasizing early risk stratification, safe pharmacotherapy, and coordinated multidisciplinary care in a low-resource setting.

Systemic Lupus erythematosus (SLE) is a multiorgan autoimmune disease that affects 20-150 per 100,000 women. It is a mutagenic disease which causes formation of autoantibodies immune complexes that leads to inflammation in different organs leading to organ damage. We present a case of a young female who was newly diagnosed to have SLE. She presented with an elevated ANA, low C3 and elevated Anti-DS DNA. She first manifested with epistaxis and subsequently experienced the various complications of SLE such as infection, thrombosis, bleeding, ascites, etc. The initial presentation of normochromic, normocytic anemia and thrombocytopenia together with further work-ups supported another concomitant autoimmune disease, namely Evan’s syndrome. Evan’s syndrome is a rare manifestation of SLE, and is observed in only 2.73% of the population. In addition, the patient manifested with sudden onset of right-sided body weakness with Cranial CT scan findings of areas of focal infarction in the frontal lobe with concomitant acute intracranial hemorrhages. The evidence of both thrombosis and hemorrhage provided conflicting management strategies for this patient. The use of hydroxychloroquine, which is the cornerstone of lupus therapy, provided beneficial antithrombotic effects. A multidisciplinary approach to management and prudent choice of medications were vital in the success of treatment on such a complicated case.

Systemic lupus erythematosus (SLE) is the most common form of lupus and a chronic autoimmune disorder that can affect multiple organ systems including the joints, skin, the cardiovascular system and even the central and peripheral nervous system. Although rare, these patients may present with neuropsychiatric symptoms. This patient presented initially with an SLE flare associated with sudden focal to generalized tonic-clonic seizures. Further rheumatologic workup was done which revealed that the patient also has scleroderma, an autoimmune connective tissue that causes inflammation of the skin and other key internal organs. Due to the seizure occurrence, cranial magnetic resonance imaging (MRI) was done which showed incidental mesial temporal sclerosis, which is the scarring of the medial part of the said lobe of the brain. Her overlap syndrome was managed with Hydrocortisone and she was given Valproic acid as her anti-epileptic drug with no recurrence of seizure afterwards.

INTRODUCTION: Hydroxychloroquine (HCQ), originally an antimalarial drug, is currently used to treat multiple disorders, especially rheumatic diseases. Given its good efficacy and safety, HCQ is widely administered in pregnant patients. However, the safety profile of HCQ during pregnancy remains controversial due to limited research. In addition, HCQ has been reported to reduce preeclampsia in patients with systemic lupus erythematosus (SLE) and could potentially alleviate the symptom of preeclampsia. However, the clinical profile and molecular mechanism of HCQ in preeclampsia is yet to be fully understood. METHOD: We reviewed the literature on HCQ treatment in pregnancy with rheumatic diseases and preeclamp-sia in PubMed and Web of Science. We also discussed the safety of long-term therapy with HCQ during pregnancy. RESULTS: HCQ mainly modulates autoimmune response through inhibition of lysosomal function, toll-like receptor (TLR) signalling, nicotinamide adenine dinucleotide phosphate-mediated oxidative stress and autophagy. Benefits of HCQ in treating rheumatic diseases, including antiphospholipid syndrome, rheumatoid arthritis and Sjogren's syndrome during pregnancy, has been demonstrated in clinics. In particular, multiple clinical guidelines recommend HCQ as an indispensable therapeutic drug for pregnant patients with SLE. Additionally, it may potentially function in preeclampsia to improve clinical symptoms. CONCLUSION HCQ is effectively used for rheumatic diseases during pregnancy. The benefits of HCQ treatment in rheumatic diseases outweigh the risk of adverse reactions it induces in pregnant women.

The remarkable efficacy of chimeric antigen receptor (CAR) T cell therapy in hematological malignancies has provided a solid basis for the therapeutic concept, wherein specific pathogenic cell populations can be eradicated by means of targeted recognition. During the past few years, CAR-based cell therapies have been extensively investigated in preclinical and clinical research across various non-tumor diseases, with particular emphasis in the treatment of autoimmune diseases (ADs), yielding significant advancements. The recent deployment of CD19-directed CAR T cells has induced long-lasting, drug-free remission in patients with systemic lupus erythematosus (SLE) and other systemic ADs, alongside a more profound immune reconstruction of B cell repertoire compared with conventional immunosuppressive agents and B cell-targeting biologics. Despite the initial success achieved by CAR T cell therapy, it is critical to acknowledge the divergences in its application between cancer and ADs. Through examining recent clinical studies and ongoing research, we highlight the transformative potential of this therapeutic approach in the treatment of SLE, while also addressing the challenges and future directions necessary to enhance the long-term efficacy and safety of CAR-based cell therapies in clinical practice.

Systemic lupus erythematosus (SLE) is an autoimmune disease accompanied by various complications, and the exact etiology remains unclear. Treatments for SLE encompass hormone therapy, plasma exchange and immunoadsorption, and targeted biological therapies. Berbamine (BBM), a cellular immunopotentiator with diverse biological functions, has not been reported to have immunomodulatory and therapeutic effects on SLE. The mice were divided into control group, model group, positive control group, low, medium and high BBM groups. In control group, C57BL/6J wild mice received intraperitoneal injection of saline. In model group, MRL/lpr lupus mice were treated with intraperitoneal injection of saline. In positive control group, MRL/lpr lupus mice received intragastric administration of hydroxychloroquine sulfate tablets [Plaquenil, 150 mg/(kg·d)]. In BBM groups, MRL/lpr lupus mice received intragastric administration of different concentration of BBM respectively [20 mg/(kg·d), 50 mg/(kg·d), 100 mg/(kg·d)]. After 8 weeks of treatment, blood was collected from the retro-orbital venous plexus, and ELISA was used to detect the levels of anti-double-stranded DNA (dsDNA) antibodies, antinuclear antibodies (ANA), and anti-small nuclear ribonucleoprotein/Sm (snRNP/Sm) antibodies. Spleen tissues were collected for analysis of Th1/Th2 ratio by flow cytometry. The RNA and protein of spleen were extracted, and the levels of T-box transcription factor T-bet and GATA3 (GATA binding protein 3) mRNA and protein were detected by qRT-PCR and Western blot. The proliferation of white blood cells in the blood was tested by blood routine test. The histopathological changes of kidneys of each group were detected by HE staining. Compared with the model group, the levels of ANA, anti-dsDNA, and anti-snRNP/Sm antibodies were significantly reduced in the BBM-treated groups. The Th1/Th2 ratio was significantly decreased in the model group, but reversed by BBM. Compared with the control group, T-bet expression was significantly downregulated, while GATA3 expression was significantly upregulated in the model group. After BBM intervention, T-bet expression significantly increased, while GATA3 expression decreased compared with the model group. The number of white blood cells significantly decreased in the model group, and increased in the BBM-treated groups. In the model group, the glomerular mesangial and endothelial cells showed significant hyperplasia, clear thrombus was observed in the dilated capillaries, and inflammatory cells infiltrated in the renal interstitium. In medium and high BBM groups, the infiltration of inflammatory cells and capillary thrombosis were significantly decreased. In conclusion, BBM exhibits certain immunomodulatory effects on SLE and promotes the proliferation of white blood cells.
