Descriptor English: Hyperhomocysteinemia
Descriptor Spanish: Hiperhomocisteinemia
Descriptor hiperhomocisteinemia
Scope note: Afección en la que están elevadas las concentraciones plasmáticas de homocisteína y metabolitos relacionados (más de 13,9 micromoles por litro). La hiperhomocisteinemia puede ser familiar o adquirida. El desarrollo de la forma adquirida se asocia principalmente con la deficiencia de vitaminas B, de folato o de ambos (p. ej., la ANEMIA PERNICIOSA, la malabsorción de vitaminas). La forma familiar frecuentemente produce una elevación más intensa de la homocisteína total y de su excreción urinaria, apareciendo HOMOCISTINURIA. La hiperhomocisteinemia es un factor de riesgo de enfermedades cardiovasculares y neurodegenerativas, fracturas osteoporóticas y complicaciones durante el embarazo.

Scope note: Condition in which the plasma levels of homocysteine and related metabolites are elevated (>13.9 μmol/l). Hyperhomocysteinemia can be familial or acquired. Development of the acquired hyperhomocysteinemia is mostly associated with vitamins B and/or folate deficiency (e.g., PERNICIOUS ANEMIA, vitamin malabsorption). Familial hyperhomocysteinemia often results in a more severe elevation of total homocysteine and excretion into the urine, resulting in HOMOCYSTINURIA. Hyperhomocysteinemia is a risk factor for cardiovascular and neurodegenerative diseases, osteoporotic fractures and complications during pregnancy.
