Su riesgo de desarrollar trastornos hemorrágicos puede aumentar por la edad, el historial familiar y genético, otras afecciones médicas y medicinas, y el sexo.

Sus genes u otras causas, como afecciones médicas o medicinas, pueden causar trastornos hemorrágicos. Algunas veces, es posible que se desconozca la causa. Cualquier problema que afecte la función o el número de factores de coagulación o plaquetas puede generar un trastorno hemorrágico.

Los trastornos hemorrágicos se pueden heredar o se pueden adquirir, es decir, que los desarrolla durante su vida. Los trastornos hemorrágicos adquiridos son más comunes que los trastornos hemorrágicos hereditarios.

Las personas que tienen la anemia de células falciformes tienen hemoglobina anormal, llamada hemoglobina S o hemoglobina falciforme, en sus glóbulos rojos. La hemoglobina es una proteína en los glóbulos rojos que transporta el oxígeno por todo el cuerpo. Las personas que tienen la anemia de células falciformes heredan dos genes de hemoglobina anormales, uno de cada padre.

If you already know you have AAT deficiency, you probably also have a related lung or liver disease. Ongoing medical care and lifestyle changes can help you manage your health. Your doctor may also talk to you about making healthy lifestyle changes such as quitting smoking, avoiding secondhand smoke and other lung irritants, and getting annual flu and pneumonia vaccines.

AAT deficiency usually is diagnosed after you develop a lung or liver disease that is related to the condition. But knowing the symptoms and getting an early diagnosis is important to help prevent serious disease, especially with treatment and lifestyle changes.

The first lung-related symptoms of AAT deficiency may include shortness of breath, less ability to be physically active, and wheezing. Some people may not have any symptoms or complications. AAT deficiency can lead to lung and liver diseases.

Alpha-1 antitrypsin (AAT) deficiency happens when you do not make enough AAT protein. The AAT protein is made in your liver. This protein enters your blood and protects your organs, including the lungs, from damage. For example, your immune system is your body’s defense against bacteria and viruses but if it is overactive, it can damage your body while fighting diseases. The AAT protein prevents you from having too much inflammation in your lungs. Without enough AAT protein, your immune system may damage your lungs and lead to lung disease.

One of the fundamental variables in preclinical biomedical research is sex: whether a cell, tissue, or animal is female or male. Biological sex is an important consideration for this research that underlies drug development, clinical trials, and prevention approaches.

NIH expects that sex as a biological variable will be factored into research designs, analyses, and reporting in vertebrate animal and human studies. Strong justification from the scientific literature, preliminary data, or other relevant considerations must be provided for applications proposing to study only one sex.
