ABSTRACT

BACKGROUND: As of 2016, ≈1.4 million people in the United States identify as transgender. Despite their growing number and increasing specific medical needs, there has been a lack of research on cardiovascular disease (CVD) and CVD risk factors in this population. Recent studies have reported that the transgender population had a significantly higher rate of CVD risk factors without a significant increase in overall CVD morbidity and mortality. These studies are limited by their small sample sizes and their predominant focus on younger transgender populations. With a larger sample size and inclusion of broader age range, our study aims to provide insight into the association between being transgender and cardiovascular risk factors, as well as myocardial infarction. METHODS AND RESULTS: The Behavioral Risk Factor Surveillance System data from 2014 to 2017 were used to evaluate the cross-sectional association between being transgender and the reported history of myocardial infarction and CVD risk factors. A logistic regression model was constructed to study the association between being transgender and myocardial infarction after adjusting for CVD risk factors including age, diabetes mellitus, hypertension, hypercholesterolemia, chronic kidney disease, smoking, and exercise. Multivariable analysis revealed that transgender men had a >2-fold and 4-fold increase in the rate of myocardial infarction compared with cisgender men (odds ratio, 2.53; 95% CI, 1.14-5.63; P=0.02) and cisgender women (odds ratio, 4.90; 95% CI, 2.21-10.90; P<0.01), respectively. Conversely, transgender women had >2-fold increase in the rate of myocardial infarction compared with cisgender women (odds ratio, 2.56; 95% CI, 1.78-3.68; P<0.01) but did not have a significant increase in the rate of myocardial infarction compared with cisgender men. CONCLUSIONS: The transgender population had a higher reported history of myocardial infarction in comparison to the cisgender population, except for transgender women compared with cisgender men, even after adjusting for cardiovascular risk factors.

ABSTRACT

Post-transfusion purpura is a rare transfusion-related complication that often goes undiagnosed. It is due to alloimmunization against platelet antigens which leads to acute profound thrombocytopenia following the transfusion of any platelet-containing product (red blood cells or platelets). It is commonly seen in multiparous women. Here, we report a case of post-transfusion purpura in a 56-year-old multiparous woman who developed acute thrombocytopenia seven days following a packed red blood cell transfusion. We will discuss the clinical presentation, diagnosis, workup and treatment of this rare disease. It is important to recognize this entity separately and to include it in the differential diagnosis of acute thrombocytopenia after a recent blood transfusion. Treatment for this condition consists of intravenous immunoglobulins, corticosteroids or plasmapheresis.

ABSTRACT

Inflammation is known to play a significant role in the process of atherogenesis and cardiovascular disease (CVD). Indeed, patients with chronic inflammatory diseases are at increased risk for cardiovascular events. However, the mechanisms linking chronic inflammation and CVD remain poorly understood. Psoriasis, a chronic inflammatory skin disease associated with a greater risk of early cardiovascular events, provides a suitable human model to study the pathophysiology of inflammatory atherogenesis in humans. Additionally, cytokines such as TNF-α, IL-17A, and other immune pathways are the common links between the pathogenesis of psoriasis and atherosclerosis, and hence the approved treatments for psoriasis, which include selective cytokine inhibition (e.g., anti-TNF, anti-IL-17A, and anti-IL-12/23) and immune modulation (e.g., methotrexate or cyclosporine), provide an opportunity to examine the effect of modulating these pathways on atherogenesis. We have been using this human model in a large, prospective cohort study, and this review summarizes our approach and results of using this human model to study inflammatory atherogenesis. Specifically, we review simultaneous multimodal imaging of several vascular beds using 18fludeoxyglucose positron emission tomography/computed tomography, 18fludeoxyglucose positron emission tomography/MRI, and coronary computed tomography angiography as well as cardiovascular biomarkers to better understand how modulation of inflammation may impact vascular diseases.
