Aortic Pathology in Systemic Lupus Erythematosus: A Case Report and Review of Literature

Fatal ascending aortic aneurysm in a patient with systemic lupus erythematosus: A case report

Aortic aneurysm is a potentially life-threatening condition with higher incidence in patients with systemic lupus erythematosus(SLE). Patients usually present with nonspecific symptoms and diagnosis is typically made incidentally through imaging studies. Management strategies include medical therapy to control inflammation and hypertension, surgical intervention for large or symptomatic aneursyms, and close monitoring for early detection of complications. We present a case of a 49-year female with multiple joint pain and other nonspecific symptoms for 7 years. Anti-ds DNA and ANA titre were significantly high and CT angiogram showed ascending aortic aneurysm measuring 5.5 cm. Conservative management was started with steroids, hydroxychloroquine, and antihypertensives, while awaiting surgery. However she suddenly collapsed, probably due to aneurysm rupture and could not be revived. Our case report therefore emphasizes the importance of close surveillance and timely intervention to minimize the morbidity and mortality in these patients.

Subclinical vascular damage in Schistosoma spp. endemic regions

Background: Cardiovascular abnormalities have been described in patients with schistosomiasis. Their true prevalence and clinical features in endemic settings are unknown. Patients and methods: The study aimed to assess the prevalence of subclinical cardiovascular damage in a population endemic to schistosomiasis. A cross-sectional study was conducted using colour-ultrasound assessment of abdominal and carotid arteries among adults aged >18 years living in Kome Island, Tanzania. Carotid intimal medial thickness, carotid plaque, mean abdominal aortic diameter, and presence of aneurysms were assessed. Anamnestic data on previous Schistosoma infection was collected; the actual prevalence of Schistosoma mansoni and Schistosoma haematobium was also assessed through stool and urine investigations. Results: A total of 264 participants (166 female, 98 male) were enrolled (mean age of 50±15.5 years). The history of previous schistosomiasis was 27.3%, and actual positivity for Schistosoma mansoni was 5.9%. The Latero-lateral Abdominal Aortic Diameter was significantly increased among participants with a previous history of schistosomiasis (16.7±2.8 mm vs. 17.6±3 mm; p=0.02), with an aOR of 1.15 [CI 1.04-1.28]; p=0.007]. Conclusions: The significant difference in the Latero-lateral Abdominal Aortic Diameter in participants with previous Schistosomiasis history schistosomiasis, suggests the need for further investigations on aortic damage in endemic populations, independently from the positive laboratory investigations.

Surgical treatment of acute aortic dissection in a patient with SLE and prior antiphospholipid syndrome on therapy for over 30 years: a case report

BACKGROUND

In patients with systemic lupus erythematosus (SLE), lengthy treatment and long-term steroid use are the main risk factors for developing aortic aneurysms or aortic dissections. In patients with cardiac tamponade, hemodynamic collapse may lead to acute renal and hepatic failure.

CASE PRESENTATION

We report the successful treatment of a 55-year-old woman with SLE since the age of 21. She suddenly felt chest pain approximately 2 weeks before developing fever and vomiting and was admitted to our hospital. Initially, she had severe liver dysfunction and was admitted to the hepatology department, where treatment for fulminant hepatitis was initiated. However, computed tomography (CT) showed an acute aortic dissection (DeBakey type II) and severe bloody pericardial effusion. Therefore, we performed emergency pericardial drainage. Plasma exchange therapy was initiated as emergency aortic surgery was deemed impossible due to impaired liver function tests and coagulation. Ten days later, the patient developed peritonitis due to small bowel perforation, and laparotomy was performed for abscess drainage and perforation closure. She had received steroid pulse therapy at the age of 21. At 40 years of age, she developed deep vein thrombosis due to antiphospholipid antibodies and was prescribed prednisolone. She was ambulatory at 3 months after the onset of acute aortic dissection, and CT revealed a rapidly enlarging true aneurysm in the distal arch. We performed elective aortic surgery. Although there were no antiphospholipid antibodies, surgery could have led to a devastating antiphospholipid syndrome. Therefore, we decided to treat the patient with triple therapy. Methylprednisolone was intravenously administered intraoperatively and at 1 day postoperatively. The patient was discharged without complications after returning to her usual oral prednisolone regimen.

CONCLUSIONS

The patient described herein had a systemic circulatory failure due to cardiac tamponade, accompanied by liver failure. This condition is a significant cause of death in patients with aortic dissection-associated SLE and is extremely dangerous. However, multi-specialty intervention helped the patient recover, and she has been attending the outpatient clinic. Aortic surgery requiring hypothermia in SLE patients with antiphospholipid syndrome and a history of thrombocytopenia or thrombosis requires a multi-disciplinary treatment team, including cardiac surgeons and medical experts.

Increased depression risk in patients with abdominal aortic aneurysm: a nationwide cohort study

Purpose

Abdominal aortic aneurysm (AAA) is a critical disease. Most studies of AAA consider reoperation rate, complications, or mortality, but do not consider a patient's mental state. However, there is a possibility of interaction between AAA and depression in disease development and prognosis. We investigated the incidence and risk ratio of depression in patients with AAA using nationwide data.

Methods

We selected subjects from National Health Insurance System database who were diagnosed with AAA between 2009 and 2015 and survived at least 1 year after diagnosis or AAA surgery (n = 10,373). We determined the control group using propensity score matching by age and sex. The control group had about 3 times the number of subjects as the AAA cohort (n = 31,119).

Results

The incidence of depression was 1.4 times higher in the AAA group than the control group. We further analyzed the incidence of depression in the AAA group according to treatment modalities (nonsurgical vs. surgical or nonsurgical vs. open surgical aneurysm repair vs. endovascular aneurysm repair) but found no significant difference among them. The incidence of depression was significantly higher in patients aged <65 years than in patients aged ≥65 years (hazard ratio, 1.539 vs. 1.270; P < 0.001).

Conclusion

The incidence of depression was higher in the AAA group, with an especially high risk for depression in patients aged <65 years. The psychiatric status of patients with AAA should be carefully monitored for clinicians to intervene when appropriate.

Prevalence, clinical features, risk factors, and outcomes of SLE patients with aortic aneurysm: a cross-sectional retrospective study in a Chinese single center

OBJECTIVES

The prevalence, clinical features, and outcomes of patients with systemic lupus erythematosus (SLE) complicated with or without aortic aneurysm (AA) were compared in a Chinese single-center cohort.

METHODS

Included in this study were SLE patients who received treatment at Shanghai Changhai Hospital between 2000 and 2020. The prevalence, clinical features, and outcomes of these SLE patients with or without AA were compared by Student's t-tests or Fisher's exact tests as appropriate. Risk factors associated with AA occurrence in SLE were evaluated by univariable and multivariable logistic regression analyses. The survival analysis between SLE patients with or without AA was conducted by the Kaplan-Meier method.

RESULTS

Of the 1843 SLE patients included in this study, 16 (0.86%) were identified as having AA, and 160 of the remaining 1825 SLE patients without AA were selected as a simple random sample for comparison. The SLE patients with AA showed a higher proportion of smoking and hypertension as compared with those with no AA. Multivariable logistic regression analysis showed that a long SLE duration and anti-RNP positivity were two independent risk factors associated with AA occurrence in SLE patients. The log rank test showed that SLE patients with AA had a significantly higher risk of progression to death. Renal disorder was associated with an even poorer outcome in SLE patients with AA.

CONCLUSION

The incidence of AA in SLE patients may be underestimated. The association between AA and SLE, especially in patients with multiple risk factors, should not be ignored. Key Points • The risk of SLE patients developing AA may be higher than that previously estimated. • The risk of SLE patients especially with multiple risk factors developing AA should not be ignored. • The diagnosis of AA should not be forgot when SLE patients present with chest, back, or abdominal symptoms with unexplained causes.

Aortic Pathology During COVID - 19 Pandemics. Clinical Reports in Literature and Open Questions on the two Co-Occurring Conditions

Background

Cardiovascular involvement in SARS-CoV-2 infection has emerged as one of viral major clinical features during actual pandemic; limb arterial ischemic events, venous thrombosis, acute myocardial infection and stroke have occurred in patients.

Acute aortic conditions have also been described, followed by interesting observations on cases, hypothesis, raised since the emergence of the pandemics.

Methods

a review of cases in literature of aortic pathology in patients with clinically suspected/microbiologically confirmed COVID-19 infection has been carried out to analyze anagraphic data, clinical presentation, treatment options and outcome.

Results

Seventeen cases have been included. Mean age of patients was 58.6 ± 15.2 years, with a male to female ratio of 12:15 (70.5% vs. 29.5%). Comorbidities were reported in 11 cases (64.7%), but in 5 cases (29.4%) no previous pathology was signaled in history. Hypertension was the most frequently reported comorbidity, in 8 cases, (47%), followed by renal pathology (17.6%), coronary artery disease (17.6%), previous aortic surgery (11.7%) and arrhythmia (11.7%); but also cerebrovascular disease, diabetes, autoimmune conditions, previous neoplasia and arrhythmia were reported once each. Fever and thoracic pain were the most frequently reported findings at presentation (8 cases, 47% each), followed by respiratory symptoms (6, 35.2%), low lymphocyte count (17.6%), features related to aneurysm rupture, ischemic stroke, abdominal pain and acute renal insufficiency. Reported aortic pathology included: type A aortic dissection (11 cases; 64.7%); new pathology of previous aortic graft (2 cases, 11.7%); 2 aortitis, 1 associated with type A aortic dissection; 1 thoraco-abdominal aortic aneurysm, 1 ruptured aortic aneurysm and 1 aortic embolizing thrombosis. Open surgery was carried out in 10 cases (58.8%), endovascular treatment in 3 (17.6%). Three patients (17.6%) died before surgery. Exitus was reported in 4 cases, with a total mortality of 23.5%.

Conclusions

Acute aortic events have occurred during pandemic in patients with clinically suspected/microbiologically confirmed COVID-19 infection. Confounding clinical features at presentation, the importance of anamnestic details (as previous vascular graft implant), the observed surgical and postoperatory challenges may suggest the need to consider the implications of the possible link between acute aortic events and SARS-CoV-2 infection, in order to promptly correctly diagnose the patient and respond to specific needs.

Many Different Patterns under a Common Flag: Aortic Pathology in HIV-A Review of Case Reports in Literature

BACKGROUND

Availability of highly active antiretroviral therapy (HAART) for HIV has prolonged life expectancy of patients but has also increased the incidence of non-AIDS comorbid conditions. Among these, there are cardiovascular diseases, and aortic involvement has been described in patients with HIV in the form of aortitis, aneurysms, or dissections. Our study aims to describe aortic pathology occurring in patients with HIV, focusing on clinical and surgical presentation, management, and outcome, through a review of cases published in literature.

METHODS

MEDLINE (www.ncbi.nlm.nih.gov/pubmed) database was reviewed for "aortitis" OR "aortic aneurysm" OR "aortic dissection" AND HIV. Research was restricted to English language. Only case reports were included. Data on patients' age, sex, traditional risk factors, timing from HIV diagnosis, pharmacological details, coinfection (syphilis, hepatitis C virus [HCV], and hepatitis B virus [HBV]), anatomical localization of lesion, presence of inflammatory involvement, rapid growing or rupture, and surgical treatment and outcomes were collected and summarized in tables.

RESULTS

Forty articles (51 cases) were included in the study. The mean age of patients was 48.8 ± 8.3 years. Male sex was preponderant (43 cases, 84.3%). Among traditional risk factors, hypertension and smoking were the most frequently reported ones (14 and 13 cases, respectively), followed by vasculopathy involving other arterial districts, dyslipidemia, diabetes, and drug addiction. In 3 cases, HIV was diagnosed in the same time as aortic pathology, whereas in most cases, aortic event occurred after five years from HIV diagnosis. In 30.5% of cases for which data on pharmacologic management were available, no treatment or poor adherence was reported. Coinfection occurred in some cases (syphilis in 6, HCV in 5, and HBV in 3). As for anatomical involvement, isolated thoracic lesions were more frequent (24, 47.1%), followed by abdominal and thoracoabdominal lesions. The etiology ranged from bacterial mycotic aneurysms to tertiary syphilis, postsurgical complications, or atherosclerosis. In 3 cases, HIV vasculitis was directly suggested, and in another 2, no other potential etiology had been diagnosed through cultural tests. Open surgical treatment was carried out in 30 cases (58.8%), and in addition, 10 endovascular (19.6%) and 2 hybrid procedures were described. Inflammatory features occurred in 7 cases, and a rapid evolution of lesions in 6. In 9 cases (17.6%), rupture occurred. Mortality was reported in 8 cases (15.7%).

CONCLUSIONS

Aortic pathology may occur in patients with HIV. The entanglement of different patterns of pathological involvement of the aortic wall, secondary to immune dysregulation, infectious process, or atherosclerotic damage that may co-occur in one single case, results in a very challenging management of the condition. Because of the increased life expectancy of patients and immigration from regions with both high HIV and coinfection prevalence, the incidence of aortic pathology could increase in the upcoming years, suggesting the urgent need for further studies to optimize management in these very complex cases.

Endovascular Treatment of Spontaneous Intracranial Internal Carotid Dissection in a Young Patient Affected by Systemic Lupus Erythematosus: A Case Report

Systemic lupus erythematosus (SLE) increases the risk of cerebrovascular events due to vascular changes, resulting in the weakening of the vessel walls. Moreover, patients with SLE have more incidence of arterial lesions such as dissections. Internal carotid dissection (ICA) is an infrequent cause of ischemic stroke, representing 2% of all ischemic events. We present a case of ischemic stroke, caused by a spontaneous dissection of intracranial ICA, treated with endovascular stent implantation, in a 22-year-old woman affected by SLE, newly diagnosed. ICA dissection with consequent ischemic stroke is an unusual first presentation of SLE disease. Our case highlights how, despite an infrequent occurrence, ICA dissection should be considered for young adults presenting with ischemic stroke, especially in those affected by SLE. This paper also shows the good technical result in the use of stenting in case of intracranial ICA dissection.
