Systematic literature review and meta-analysis of Clostridium septicum aortitis.

BACKGROUND: Clostridium septicum bacteremia is often associated with occult malignancies (approximately 80%), especially of the right colon. Furthermore, inflammation of the aortic wall can rapidly lead to aneurysm induction through bacterial seeding into atheromatous lesions with consecutive life-threatening rupture. We summarize all published data on this rare and lethal disease to evaluate therapeutic approaches and give valid treatment recommendations because there are no guidelines. METHODS: A systematic review of the literature was conducted screening EMBASE and MEDLINE databases following the PRISMA guidelines with search period from first description to August 25, 2021. RESULTS: There were 72 cases of C septicum aortitis reported in 64 publications. Endovascular aortic repair (EVAR) was performed in a minority of patients (n = 6) unfit for surgery but lacked long-term survivors. Antibiotic treatment was beneficial in a bridge to surgery concept, but up to now harbored a 6-month mortality rate of 100% (median overall survival, 0.5 months) when no additional aortic repair was performed. Open aortic repair was the only potential curative approach but was accompanied with a 90-day-mortality of 26.7% (4/15). CONCLUSIONS: Open aortic repair combined with perioperative antibiotic treatment should be offered to all patients as the only potentially curative approach. If applicable, resection of a coexisting colonic tumor should be performed after successful aortic repair. Alternatively, long-term antibiotic treatment can be offered to patients unfit for surgery in a palliative setting. Endovascular aortic repair has been performed on a minority of patients with a high risk for stent graft infection and should remain a salvage strategy when therapeutic pressure demands acute intervention in patients unfit for surgery.

Aortic involvement in relapsing polychondritis: case-based review.

Relapsing polychondritis is a systemic inflammatory disease that mainly affects ears, nose, eyes, joints, and large airway. Relapsing polychondritis may also affect cardiac valves and large vessels with the aorta being most frequently involved. We conducted a systematic literature review to delineate the clinical characteristics, treatment, and outcome of relapsing polychondritis patients with aortic involvement including thoracic and abdominal aorta, aortic valve, and coronary arteries. 113 patients reported in 85 manuscripts were retrieved through the systematic literature search and references of the selected manuscripts. With the addition of a patient from our center, a total of 114 patients were included in the analyses. Aortic vessel involvement was the predominant type of involvement that was identified in 93 (82%) patients, while aortic valve involvement was identified in 41 patients (36%). The median age at aortic involvement was 37 years [IQR: 30-53] with a delay of 5 years [IQR: 1-8] between first relapsing polychondritis symptom and aortic involvement. Nineteen percent of the patients were asymptomatic at the time of aortic involvement diagnosis. The initial treatment was immunosuppressives in 41 patients (56%) and surgery in 28 patients (38%). The mortality ratio was 27% in a 24 month follow-up [IQR: 7.5-54 months]. Aortic dissection or rupture was the most frequent causes of mortality. Concomitant coronary artery involvement suggested a worse outcome. Aortic involvement in relapsing polychondritis is a mortal complication despite medical and surgical treatments. It may be asymptomatic in 19% of the patients which warrants the importance of screening.

Noninfectious aortitis: A case report.

INTRODUCTION: Noninfectious aortitis has been increasingly reported worldwide with a growing prevalence in western medicine. Attributed to our increasingly diverse population, western surgeons must be vigilant to promptly differentiate these cases from its more common infectious counterpart in order to ensure subsequent appropriate management of these patients. METHODS: We present a case report of a 71-year-old Indo-Caribbean male who presented with nonspecific abdominal and back pain, found to have aortitis of a noninfectious etiology.Results and conclusion: While our patient's process was ultimately managed without surgical intervention, the varied clinical presentation along with the lack of specific laboratory markers pose a challenge for surgeons to appropriately diagnose and manage aortitis. Appropriate diagnostic imaging, the utilization of a multidisciplinary team, and close patient monitoring are key components for effective management of this increasingly prevalent disease process.

[Syncope, pain in the large joints, and painful swelling of the right eye in a 51-year-old patient : Pitfalls in the diagnosis and treatment of a rare disease]. / Synkope, Schmerzen der großen Gelenke und schmerzhafte Rötung des rechten Auges bei einer 51-jährigen Patientin : Fallstricke in Diagnostik und Therapie einer seltenen Erkrankung.

In the present case we report on a 51-year-old patient diagnosed with Cogan syndrome. This vasculitis of variable vessel size is a rare disease that poses a major challenge for the correct diagnostics and therapy. In the classic setting, it comprises a triad of non-syphilitic interstitial keratitis as well as hearing loss with vestibular dysfunction. A vascultis-related aortitis, an uncertain, more likely degenerative structure in combination with strongly elevated inflammation parameters was misinterpreted as infective endocarditis for a long time and treated with anti-infective medications. After diagnosis the patient recovered following treatment with high-dose steroids and in the further course cyclophosphamide and tumor necrosis factor­α blockers.

Giant abdominal aortic aneurysm of uncommon etiology due to Behçet disease.

Behçet disease is a multisystem disorder presenting with recurrent oral and genital ulcerations as well as with ocular involvement. Vascular involvement can occur in up to 50% of affected patients. Arterial aneurysms are often multiple and are characterized by a saccular configuration with increased risk of unexpected rupture, thrombosis, and aneurysm recurrence. Here we report a case of giant infrarenal abdominal aortic aneurysm in a 34-year-old man with Behçet disease who underwent aneurysmorrhaphy and aortobifemoral bypass.

Granulocyte-colony stimulating factor-associated aortitis in a woman with advanced breast cancer: a case report and review of the literature.

BACKGROUND: Granulocyte-colony stimulating factor (G-CSF) is increasingly been used to prevent febrile neutropenia (FN) associated with the administration of chemotherapy for various cancers. The most common adverse effects of G-CSF are bone pain and injection-site reactions and aortitis has rarely been reported. We report herein a rare case of G-CSF associated with aortitis in a woman with advanced breast cancer. CASE PRESENTATION: A 72-year-old woman with estrogen receptor-negative human epidermal growth factor 2-positive breast cancer with distant metastases in the lung was admitted. Her treatment was initiated with docetaxel in combination with trastuzumab and pertuzumab followed by the supportive use of a long-acting G-CSF, pegfilgrastim. After administration of pegfilgrastim on day 5, the patient had an intermittent fever (body temperature up to 39.6 °C) on day 9 which continued irrespective of taking levofloxacin. She visited our outpatient clinic on day 13 with no objective symptoms other than fever. Laboratory tests revealed a high neutrophil count (15,000/µl) and a high C-reactive protein (CRP) level (46.35 mg/dl) without any other abnormalities. There was no response upon administration of antimicrobial agents. An 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) revealed thickening of the wall of the descending thoracic aorta and left pleural effusion. Therefore, thoracic aortitis induced by pegfilgrastim was suspected. On day 19, the fever resolved spontaneously followed by a gradual reduction in the neutrophil count and CRP level. In the follow-up CT, the aortic wall thickness and pleural effusion had disappeared. CONCLUSIONS: G-CSF may cause aortitis due to stimulation of the production of inflammatory cytokines. In case of high continuous fever after administration of pegfilgrastim, aortitis should be suspected unless there are other infectious findings.

Aortitis caused by antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis: a case-based review.

Antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) is a systemic necrotizing small vessel vasculitis primarily affecting elderly patients. Neutrophil apoptosis and release of pro-inflammatory mediators promote small vessel inflammation and hence multi-organ disease. It rarely affects larger vessels with extremely rare aortic involvement. Diagnosis is made based on clinical presentation, tissue biopsy of affected organ, as well as immunofluorescence and ELISA assays for ANCA. Management includes immunosuppression (e.g., glucocorticoids, cyclophosphamide and rituximab) and supportive therapy. We present a rare case of a younger patient with AAV involving the aorta. The patient's diagnosis was supported by clinical presentation, systemic organ involvement, strongly positive c-ANCA, and skin as well as aortic tissue biopsy results. After failing multiple immunosuppressants, he responded well to rituximab with improved symptoms, inflammatory markers, and imaging findings. Based on our literature review, we were only able to find ten cases of ANCA-related vasculitis involving the aorta. This is the first reported case of successful treatment of AAV-related aortitis using rituximab. Our case report and literature review provide insight into treatment of severe cases of AAV with aortic involvement.

Clostridium septicum Bacteremia As the Presenting Sign of Colon Cancer.

Colon cancer is one of the leading causes of morbidity and mortality throughout the world. Some of the most common presenting signs are a change in bowel habits, alteration of fecal contour or consistency, blood in stool, fatigue, and weight loss. However, it may present insidiously. This is the case of an 81-year-old female with Clostridium septicum bacteremia as the primary presenting sign of metastatic colon cancer. In further literature review, we discuss the genomic associations that contribute to the severity of the disease and explore the potential links between the gut microbiome and colorectal carcinoma. This article highlights risk factor modifications and lab abnormalities that may be useful for the primary care provider and acute care practitioner.

Isolated Abdominal Aortitis Following a Urinary Tract Infection.

A 49-year-old female with a history of sporadic episodes of scleritis was initially seen by her primary care physician (PCP) due to a two-day history of cramping abdominal pain, new elevated high blood pressure, increased urinary frequency, and urgency. The patient was diagnosed with an acute cystitis supported by a positive urine culture for a pan sensitive Escherichia coli; however, after two courses of antibiotics as an outpatient, her blood pressure (BP) remained markedly elevated, and her abdominal pain got worse which prompted a computed tomography (CT) abdomen and pelvis with contrast revealing inflammatory changes consistent with aortitis. The diagnosis was supported by a magnetic resonance angiography (MRA) which showed wall thickening and enhancement extending for approximately 4.8 cm involving the abdominal aortic wall just prior to the bifurcation. An extensive work up including CTA, US doppler of four-limbs, and fluorodeoxyglucose (FDG)-positron emission tomography (PET) confirmed the isolated abdominal aortitis. After infectious etiologies were ruled out, the patient was started on prednisone 60 mg daily which resulted in marked improvement of her symptoms. After a four-month taper of steroids, the patient had complete resolution of her symptoms, with no signs of recurrence.

Long-term function of Hydrofit as hemostatic sealant: abridged republication.

The newly-designed hemostatic sealant, Hydrofit, was developed in Japan and consists of a urethane-based polymer without blood products. By applying Hydrofit gel to an anastomosis site on the aorta, water contact initiates a chemical change in the forming elastomer which adheres rapidly and tightly. We experienced an extirpation of Hydrofit gel that had been applied 4 years and 8 months previously in a 42-year-old female who underwent aortic valve replacement and graft replacement of the ascending aorta. The Hydrofit left around the aortic graft suture line was without infection and functioned very well as an elastic sealant for a long period.

Saprochaete capitata aortitis in an immunocomopetent patient after myocardial revascularization.

Saprochaete species infection is a rare fungal disease reported so far only in immunocompromised patients. We describe the first case of aortitis caused by Saprochaete capitata, presenting as ascending aorta aneurysm, with secondary endophthalmitis in an immunocompetent patient. Infection by Saprochaete capitata is potentially fatal, with a mortality ranging from 50% to 90% of cases. In the present case aortic aneurysm caused by Saprochaete capitata aortitis was successfully treated by the combination of accurate diagnosis with surgical and specific antifungal therapy.

Aortitis which developed after the administration of granulocyte-colony stimulating factor.

Drug-induced aortitis is rare; thus, the diagnosis of drug-induced aortitis could be delayed unless clinicians are aware of the disease entity. Herein, we describe the case of a 66-year-old woman who developed aortitis after administration of granulocyte-colony stimulating factor (G-CSF) during chemotherapy for her breast cancer. Thickening of the aortic wall was clearly detected by computed tomography (CT) and magnetic resonance imaging. After excluding the other possible aetiologies, an association between G-CSF and the development of aortitis was highly suspected. Corticosteroid treatment rapidly regressed the aortitis, as confirmed by follow-up CT examination. G-CSF analog is generally well tolerated; however, there are limited case reports of G-CSF-associated aortitis, suggesting the causative effect of G-CSF in the development of aortitis. Currently, G-CSF-associated aortitis has received little attention among rheumatologists. As the delayed diagnosis results in irreversible changes in the aorta, not only oncologists but also rheumatologists should be aware of this unrecognized disease entity, G-CSF-associated aortitis.

Myocarditis and carotidynia caused by Granulocyte-Colony stimulating factor administration.

A 59 year-old woman was treated with adjuvant chemotherapy for triple negative breast cancer (TNBC) stage IB. She received pegfilgrastrim as secondary prophylaxis of neutropenia. After administration of pegfilgrastrim on day 11, she was hospitalised because of carotidynia and myocarditis that improved with antibiotics and steroids as an infection was suspected. Once she was recovered, another cycle of chemotherapy with pegfilgrastrim was administrated. At this time, the patient presented to our hospital with fever, odynophagia and chest pain, with diagnosis of myocarditis coupled with cardiogenic shock. She received antibiotics and steroids, advanced life support and also a pericardial window was done, with recovery of her condition. After a complete evaluation and exclusion of other possible aetiologies, we concluded that pegfilgrastrim was responsible for inducing carotidynia and myocarditis. Few cases have been published about Granulocyte-Colony stimulating factor (G-CSF) induced carotidynia and aortitis. However, this is the first reported case about G-CSF induced myocarditis and carotidynia.

Lupus Aortitis Successfully Treated with Moderate-dose Glucocorticoids: A Case Report and Review of the Literature.

Lupus aortitis is a rare and potentially life-threatening disorder. Previous studies have reported the utility of high-dose systemic glucocorticoids or surgery as the treatment, although there have been no related controlled trials. We herein report a 49-year-old woman with a 35-year history of systemic lupus erythematosus who was diagnosed with aortitis. Her symptoms and laboratory and imaging abnormalities rapidly resolved upon the administration of moderate-dose glucocorticoids. We subsequently performed a literature review of similar cases to identify the appropriate treatment and discuss these cases. A study of further cases will be needed to identify the characteristics of patients who would benefit from moderate-dose glucocorticoid therapy.

G-CSF-induced aortitis: Two cases and review of the literature.

BACKGROUND: Febrile neutropenia is generally recognised as a complication of myelosuppressive chemotherapy. Recombinant human granulocyte colony stimulating factor (G-CSF) is commonly used as a primary or secondary prophylaxis to reduce the degree and duration of neutropenia in patients at risk of developing chemotherapy-induced neutropenic fever and infectious complications. G-CSF is known to decrease mortality and increase the possibility of maintaining adequate chemotherapy dose intensity and density, which is essential in curable malignancies. Common side effects are generally mild. However, potentially fatal adverse events have also been reported. CASE PRESENTATION: Herein, we summarise previously reported and report two new independent cases of G-CSF-induced aortitis, both in patients treated with chemotherapy for breast cancer. The two cases, identified only a few months apart, share several common characteristics including type of cancer, gender, age, chemotherapy, G-CSF treatment regimen, and time span from G-CSF initiation to aortitis manifestation. The two cases were both diagnosed by CT scan and successfully treated with corticosteroids along with discontinuation of G-CSF. CONCLUSION: This case report highlights that although aortitis is a rare adverse event of G-CSF treatment, it should be considered in cases of unexplained fever and/or clinical and laboratory findings that do not respond to antibiotics.
