What is the usual source of pulmonary emboli

IgE is the immunoglobulin associated with allergic reactions and is often elevated in patients with asthma. When a person with asthma is exposed to an allergen, their IgE levels increase, leading to the release of inflammatory chemicals such as histamine, which can cause bronchoconstriction and other symptoms of asthma.

IgA: This is an immunoglobulin that plays a role in the immune system's defense against infections. It is mainly found in the mucous membranes of the respiratory and gastrointestinal tracts.

IgG: This is the most abundant immunoglobulin in the bloodstream and plays a role in providing immunity against bacterial and viral infections. It can also cross the placenta and provide passive immunity to a developing fetus.

IgM: This is the first immunoglobulin produced in response to an infection and plays a role in the body's defense against bacterial and viral infections. It is found primarily in the bloodstream.

Primary hypertension, also known as essential hypertension, refers to high blood pressure that has no identifiable underlying cause. Risk factors for developing primary hypertension include a family history of hypertension, age, obesity, smoking, sedentary lifestyle, stress, and certain dietary factors.

Specifically, diabetes mellitus is a risk factor for hypertension due to the effects of insulin resistance and hyperinsulinemia on the blood vessels, as well as the increased prevalence of obesity and other comorbidities. Moderate alcohol consumption (up to 1 drink per day for women and up to 2 drinks per day for men) may actually have a protective effect against hypertension, but excessive alcohol intake can raise blood pressure and contribute to the development of hypertension.

Asian race is not a significant risk factor for primary hypertension, although there may be differences in the prevalence and severity of hypertension among different racial and ethnic groups.
