Hereditary thrombophilia as a possible risk factor for severe disease in COVID-19: a case series.

PURPOSE: The risk factors that modulate one's susceptibility for severe COVID-19 have been well documented. Despite this, hypercoagulability remains an often overlooked risk factor for severe disease for COVID-19. Because COVID-19 infection is a risk factor for hypercoagulability, a reasonable presumption/hypothesis is that patients with hereditary thrombophilia would be at a higher risk of thrombotic complications associated with COVID-19 infection. METHODS: This case report details two cases where previously unknown hereditary thrombophilias likely contributed to the mortality of COVID-19 patients. RESULTS: The first COVID-19 patient's cause of death was pulmonary thromboemboli from deep vein thrombosis due to heterozygous MTHFR C667T and heterozygous PAI-1 4G/5G mutations. The second COVID-19 patient's cause of death was an acute myocardial infarct due to a coronary artery thrombosis in the setting of heterozygous MTHFR A1298C and homozygous PAI-1 4G/5G mutations. In each case, COVID-19 infection was also considered contributory to death. CONCLUSION: The occurrence of these fatal thrombotic events in COVID-19 patients with hereditary thrombophilias raises questions as to whether this combination of thrombotic risk factors for hypercoagulability may have placed patients at a significant enough risk to experience these fatal thrombotic complications. Thus, while not sufficient alone to prove that SARS-CoV-2 patients with hereditary thrombophilias are at increased risk for thrombotic complications, these two cases indicate that further investigation is warranted into elucidating the relationship between thrombotic risk factors as it may identify an additional high-risk medical condition for COVID-19 and have important diagnostic and therapeutic ramifications.

Pulmonary Thromboemboli Due to Leiomyoma.

ABSTRACT: Uterine leiomyomas are the most common pelvic tumor in women and the most frequent indication for hysterectomy. Although benign lesions, leiomyomas can cause dysfunctional uterine bleeding, pelvic pain or discomfort, infertility, and spontaneous abortion. Despite the fact that uterine leiomyomas can result in a significant amount of morbidity, it is relatively rare for these common tumors to lead to death. Here we present a case of fatal pulmonary thromboembolism that occurred due to pelvic vein thrombosis in the setting of leiomyomas.

A Case of Spontaneous Coronary Artery Dissection in the Setting of Exogenous Testosterone.

ABSTRACT: Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome, occurring when there is separation of the coronary artery walls by intramural hemorrhage creating a false lumen. This compresses the arterial lumen, compromising the ability of the coronary artery to perfuse the myocardial tissue. Spontaneous coronary artery dissection is usually fatal, with risk factors including pregnancy, young age, and female sex, birth control, and other hormonal therapies.In this case report, we describe the case of a 31-year-old biological female transitioning to male with exogenous testosterone who experienced a SCAD. Given the known risk factors for SCAD, such as pregnancy and exogenous hormone therapy, this case raises additional considerations regarding rare unintended consequences of testosterone therapy.

Sphingomonas paucimobilis Bacteremia in a Patient With Retropharyngeal Abscess.

Sphingomonas p aucimobilis is a nonfermenting gram-negative bacillus that is widely distributed in both community environments and hospitals. Various infections have been identified in humans, but most have been limited to case reports. When reported, it is most commonly nosocomial infections associated with contaminated hospital equipment such as indwelling catheters, ventilators, hemodialysis devices, and very rarely upper respiratory tract infections. We report an unusual presentation of S . paucimobilis infection. This case report describes a 59-year-old immunocompetent man who presented with a retropharyngeal abscess. Blood culture was positive for S . paucimobilis. The patient was treated for a total of 21 days of intravenous (IV) cefepime and oral (PO) metronidazole. He showed significant improvement and was discharged home with no medical sequelae.
