Antiphospholipid Syndrome and Antibodies Associated With Malignancy and Older Age: A Retrospective Study.

BACKGROUND: Antiphospholipid syndrome (APLS) is an established cause of thrombosis and hypercoagulability. However, the clinical characteristics of those with APLS or patients with positive antiphospholipid antibodies (APLA) in the embolic stroke of undetermined source (ESUS) have not been well studied. METHODS: A retrospective analysis was conducted between January 1, 2010, and December 31, 2020, across all three Mayo Clinic sites. Patients who were included in the study were tested for APLA and had a diagnosis of ESUS. Baseline characteristics, radiographic parameters, and outcome data were collected and compared between those who tested positive for APLS or had positive APLA and those who were negative. RESULTS: A total of 206 patients were included in the study. Eight (4%) patients were diagnosed with APLS, and 21 (10%) patients had positive APLA. On comparing those with a diagnosis of APLS and those without, patients with APLS were found to be significantly older (75 years old ± 9 vs. 58 years old ± 14, p = 0.001) and were more likely to have a history of cancer (50% vs. 13%, p = 0.012). Those with positive APLA had similar findings of being older (67 years old ±13 vs. 58 years old ± 14 p = 0.003) and more likely to have a history of cancer (29% vs. 8.4% p = 0.027). Radiographically, those with APLS had a higher white matter disease burden (Fazekas score median 2 (IQR 1.5-3) vs. median 1 (IQR 1-2), p = 0.028). CONCLUSION: Both APLS and positive APLA are associated with older age and a history of malignancy. These findings highlight the importance of considering a hypercoagulable evaluation even in the elderly ESUS population.

Concomitant presentation of eosinophilic or oncocytic mucoepidermoid carcinoma, immunoglobulin G4-related disease, and adult-onset asthma and periocular xanthogranuloma: Case report of 3 uncommon clinical entities.

RATIONALE: Immunoglobulin (Ig) G4-related disease (IgG4-RD) reportedly has a strong relationship with adult-onset asthma and periocular xanthogranuloma (AAPOX) and may be linked to sclerosing mucoepidermoid carcinoma (MEC). We present a rare case of IgG4-RD and AAPOX occurring in a patient with resected eosinophilic or oncocytic MEC. PATIENT CONCERNS: A 52-year-old woman was referred to our rheumatology clinic in 2020 to be evaluated for suspected IgG4-RD. DIAGNOSES: The patient had diagnoses of periorbital xanthelasmas, worsening glucocorticoid-dependent chronic rhinosinusitis and adult-onset asthma, and cervical lymphadenopathy persisting 2 years after resection of a low-grade MEC of a minor salivary gland. INTERVENTIONS: Because the patient's symptomatic relief was glucocorticoid dependent, IgG4-RD was suspected, and she was referred to our medical center. Her amylase and lipase levels were elevated. Serum IgG4 levels were initially within normal limits, but IgG4-RD was diagnosed because of the presence of lymphadenopathy and evidence of pancreatitis, which was shown on positron emission tomography/computed tomography. Furthermore, the IgG4 levels later increased without explanation. After the patient began combination therapy with a glucocorticoid (prednisone) and methotrexate, her symptoms improved but recurred when the daily oral glucocorticoid dosage decreased below 10 mg. An excisional biopsy of her right submandibular gland in 2021 yielded results consistent with IgG4-RD. In addition, AAPOX was diagnosed, given the presence of periocular edema and plaques, adult-onset asthma, and rhinosinusitis. OUTCOME: The patient was carcinoma free at last follow-up and was receiving medication to treat the other conditions. LESSONS: The diagnosis of these 3 concomitant, uncommon entities required approximately 7 years of medical investigations. Clinicians should know that IgG4-RD, AAPOX, and MEC may occur together.

Migraine with Visual aura and the Risk of Stroke- a Narrative Review.

OBJECTIVES: Patients with migraine with visual aura (MwvA) often present to eye care providers for evaluation. A thorough ophthalmological history and examination is needed to exclude ophthalmologic disorders. Additionally, it has been increasingly recognized that MwvA is associated with ischemic stroke (IS). The aim of this narrative review is to provide a comprehensive overview of the differential diagnosis of MwvA and its association with IS. MATERIALS AND METHODS: We conducted a PubMed search using key words including "migraine aura", "visual aura without headache", "late onset migraine accompaniment", "migraine and stroke", "migraine and atrial fibrillation", and "migraine and patent foramen ovale (PFO)". We narratively summarized the main findings of the identified studies in sections including age of onset and frequency of migraine with aura, stroke subtypes, and the role of cardioembolism in the migraine-stroke association. RESULTS AND CONCLUSION: For women younger than 50 years, MwvA is associated with an increased risk of IS, and the risk further increases in patients who also smoke and use oral contraceptives. Age of onset of MwvA 50 years or greater is associated with IS that occurs in late life. Studies reported that increased frequency of aura is associated with an increased risk of IS in women. MwvA is associated with an increased risk of cardioembolic stroke and a higher incidence of atrial fibrillation compared to migraine without aura. Most studies that assessed the migraine-stroke association were based on patients with MwvA. The risks of stroke associated with other types of migraine aura or aura without headache, as well as such association in men require further investigation. More data is needed to determine the absolute risk of stroke when evaluating MwvA in situations including smoking and low dose estrogen use, new or late onset (>50 years) MwvA, to facilitate the development of practice guidelines for stroke prevention in specific clinical scenarios.
