Pulmonary hemorrhage and lupus

A 14-year-old patient presents with hematuria and proteinuria. Clinical evaluation reveals a positive anti-nuclear antibody titer, positive anti-double stranded DNA antibody and hypocomplementemia. Systemic lupus erythematosus (SLE) is diagnosed based on the 2019 EULAR/ACR (European League Against Rheumatism/American College of Rheumatology) classification criteria (Aringer et al. Arthritis Rheumatol 71:1400-1412, 2019). A kidney biopsy is performed that confirms the presence of immune complex glomerulonephritis, ISN-RPS (International Society of Nephrology/Renal Pathology Society) class IV (Bajema et al...

With the development of modern medical standards, autoimmune diseases and their associated successive osteoporosis have received increasing attention in recent years. Patients with autoimmune diseases, due to the characteristics of the disease and the prolonged use of glucocorticoid hormone therapy, may affect the bone formation and bone absorption of the patient, followed by severe successive osteoporosis, thereby increasing the risk of osteoporotic vertebral fractures. Vertebral compression fractures of the spine are common fracture types in patients with osteoporotic fractures...

Systemic Lupus Erythematosus (SLE) is a multifaceted, multisystem autoimmune disorder with diverse clinical expressions. While prevalence reports vary widely, pulmonary involvement accounts for significant morbidity and mortality in SLE. This comprehensive review explores the spectrum of pulmonary disease in SLE, including upper airway manifestations (e.g., laryngeal affection), lower airway conditions (e.g., bronchitis, bronchiolitis, bronchiectasis), parenchymal diseases (e.g., interstitial lung disease, acute lupus pneumonitis, diffuse alveolar hemorrhage), pleural diseases (e...

BACKGROUND: Nearly half of the Systemic lupus erythematosus (SLE) patients develop lung involvement. The study assessed the extent of pulmonary involvement among SLE patients and to identify the associated factors in the population. METHODOLOGY: This retrospective cohort study was conducted at Aseer Hospital and Khamis Myshat Hospital in the Southern region of Saudi Arabia. The study spanned from January 1, 2016, to June 3, 2023. Patient inclusion criteria encompassed individuals who received a definitive diagnosis and classification as per American College of Rheumatology criteria, while patients under 18 years of age and those with mixed connective tissue diseases were exclude...

BACKGROUND: Growing evidence showing that systemic autoimmune diseases (SADs) are associated with a high risk of atrial fibrillation (AF). However, the impact of SAD on the clinical course of AF patients is largely unknown. METHODS: Retrospective cohort study within a federated healthcare network (TriNetX). Using ICD codes, AF patients on anticoagulant therapy were categorized according to the presence of SAD (M32: Systemic Lupus Erythematosus (SLE); M33: Dermato-polymyositis (DMP); M34: Systemic Sclerosis (SSc); M35: Sjogren syndrome)...

OBJECTIVE: Pulmonary arterial hypertension (PAH) represents an important vascular complication of mixed connective tissue disease (MCTD) and systemic sclerosis (SSc). Microvascular involvement in these diseases can be investigated by means of nailfold capillaroscopy (NFC). Microvascular involvement detected in the nailfold bed is the mirror of the microvascular damage occurring in the entire body, further indicating the involvement of the target organs. The aim of this study was to evaluate the microvascular involvement in MCTD patients with or without PAH, compared to that found in SSc patients with or without PAH...

BACKGROUND: The assessment of nail changes in connective tissue diseases (CTD) has been rarely explored in previous studies. The use of dermoscopy to study vascular changes in nailfolds is an interesting diagnostic technique. The aim of the study was to describe the epidemiological, clinical, and dermoscopic features of nail lesions in CTD. METHODS: A prospective study was performed at the Dermatology Department of Habib Thameur Hospital (Tunis, Tunisia) in collaboration with the Internal Medicine Department over a period of 15 months, from July 2020 to September 2021, including patients diagnosed with systemic sclerosis (SS), systemic lupus erythematosus (SLE) and dermatomyositis (DM)...

In situ pulmonary artery thrombosis (ISPAT) is a relatively rare but potentially life-threatening complication of systemic lupus erythematosus (SLE) in children. We report the case of a 12-year-old girl who presented with fever, chest pain, and dyspnea. Immune thrombocytopenia was identified due to purpura and menorrhagia 3 months before presentation with a lowest platelet count of 12 × 109 /L. The sudden onset of fever, chest pain, and dyspnea were misdiagnosed as hyperinflammatory responses caused by pneumonia; these symptoms ameliorated with glucocorticoid and antibiotic treatment...

OBJECTIVE: The annual hospitalization rate of patients with systemic lupus erythematosus (SLE) is approximately 10%, and hospitalizations are responsible for most of the healthcare expenses. Herein, we analyzed 5-year hospitalization data of SLE patients and determined factors leading to hospitalization. METHODS: Clinical, laboratory, and hospitalization data of SLE patients admitted to our rheumatology clinic in 2015-2020 were retrieved from our SLE database and analyzed...

Antiglomerular basement membrane disease (anti-GBM) is an unusual cause of glomerulonephritis. Patients usually present with rapidly progressive glomerulonephritis with or without pulmonary hemorrhage. The diagnosis is based on linear deposits of IgG along the GBM and the presence of anti-GBM antibodies. However, cases with atypical anti-GBM disease in which an anti-GBM antibody was not detected have been reported. We report a 29-year-old pregnant woman with underlying systemic lupus erythematosus (SLE) who presented with severe glomerulonephritis due to atypical antiglomerular basement membrane disease...

The pulmonary manifestations of Systemic Lupus Erythematosus (SLE) in pediatric patients are poorly understood and the pulmonary manifestations reported from the adult population are generally extrapolated to the pediatric population. In the present work, the review of 228 files was carried out, in which the pulmonary manifestations, symptoms and antibody levels of the patients treated at the Hospital Regional de Alta Especialidad de Ixtapaluca (HRAEI), State of Mexico, Mexico, were identified. Statistical significance between groups was estimated using the Chi-square and Mann-Whitney U test...

Electrical impedance tomography (EIT) as a bedside, noninvasive, radiation-free technology, could quantify alveolar collapse and over-distension and provide real-time ventilation images of lungs. Clinical studies have shown potential benefit in reducing lung injury by EIT to guide mechanical ventilation setting in acute respiratory distress syndrome (ARDS). The respiratory management of ARDS with venous-venous extracorporeal membrane oxygenation (VV ECMO) remains a challenge for ICU doctors. Moreover, EIT has gained great interests in the respiratory management in VV ECMO therapy...

OBJECTIVES: To describe the pulmonary involvement in patients with catastrophic antiphospholipid syndrome (CAPS), focusing on its relationship with extrapulmonary involvement, laboratory, radiological, and pathological findings. METHODS: This retrospective cross-sectional study includes all patients grouped in the "CAPS Registry". All cases were reviewed, and those with pulmonary thromboembolism (PE) and/or diffuse alveolar hemorrhage (DAH) were selected. Data on pulmonary and extrapulmonary clinical presentation, radiologic patterns, laboratory findings, associated autoimmune diseases, treatments, and outcomes were analyzed...

BACKGROUND: Dysregulated long noncoding RNA (lncRNA) expression with increased apoptosis has been demonstrated in systemic lupus erythematosus (SLE) patients with alveolar hemorrhage (AH). SNHG16, a lncRNA, can enhance pulmonary inflammation by sponging microRNAs, and upregulate toll-like receptor 4 (TLR4) expression via stabilizing its mRNAs. TRAF6, a TLR4 downstream signal transducer, can induce autophagy and NETosis formation. In this study, we investigated whether SNHG16 could regulate TLR4-mediated autophagy and NETosis formation in SLE-associated AH...

Introduction: Diffuse alveolar hemorrhage (DAH) is a serious complication caused by systemic lupus erythematosus (SLE). Tissue damage and changes in immune response are all associated with excessive free radical production. Therefore, removing excess reactive oxygen species are considered a feasible scheme for diffuse alveolar hemorrhage treatment. Cyclophosphamide is often used as the main therapeutic drug in clinics. However, CTX carries a high risk of dose-increasing toxicity, treatment intolerance, and high recurrence rate...

BACKGROUND: Diagnosis and management of dengue hemorrhagic fever (DHF) can be challenging in the presence of confounding comorbidities. Important confounders are conditions that alter hematological parameters and intra/extra vascular fluid distribution. We report the case of a patient with active lupus nephritis, who developed DHF with subsequent bleeding and fluid overload. This is the first case report to highlight a unique set of diagnostic and therapeutic challenges in DHF in this context...

Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune disease characterized by a wide range of clinical manifestations affecting multiple organs. While standardized diagnostic criteria are commonly used, the lack of pathognomonic presenting signs and symptoms often makes the diagnosis challenging. Of the many pulmonary manifestations, diffuse alveolar hemorrhage (DAH) is one of the most severe complications caused by the disruption of the capillary alveolar interface. Although this condition is rarely encountered, it has a rapidly progressive course and can be life-threatening, which warrants a prompt diagnostic workup and an aggressive therapeutic approach...

Postpartum pulmonary syndrome as lupus flares in inactive or mild lupus is uncommon. The diagnosis and management of postpartum lupus flare in second pregnancy presenting with crescentic lupus nephritis (LN), secondary thrombotic microangiopathy (TMA), and severe lupus vasculitis in an undiagnosed systemic lupus erythematosus is extremely challenging. Here, in this case report, we present a young lady who presented with postpartum acute kidney injury (AKI) with systemic complaints about 4 weeks post-term uneventful delivery...

The spectrum of pulmonary manifestations associated with mixed connective tissue disease ranges from pulmonary hypertension and interstitial lung disease to pleural effusions, alveolar hemorrhage, and complications from the thromboembolic disease. Interstitial lung disease in mixed connective tissue disease is a frequently occurring entity, although in most cases it tends to be self-limited or slowly progressive. Despite this, a significant percentage of patients may present a progressive fibrosing phenotype, thus posing a great challenge regarding its therapeutic approach, given the scarcity of clinical studies that compare the efficacy of immunosuppressants available to date...

SIGNIFICANCE: Pulmonary involvement in childhood-onset systemic lupus erythematosus (cSLE), contributes to significant morbidity and mortality. Manifestations include chronic interstitial pneumonitis, pneumonia, pleuritis, alveolar hemorrhage, and shrinking lung syndrome. However, many patients can be asymptomatic from a respiratory standpoint and still have pulmonary function test (PFT) abnormalities. Our aim is to describe PFT abnormalities in patients with cSLE. METHODS: We completed a retrospective review of 42 patients with cSLE followed at our center...
