Central pontine myelinolysis scenario the CPM is caused by polydipsia leading to low blood sodium levels (hyponatremia). In schizophrenic patients with psychogenic polydipsia, inadequate thirst reception leads to excessive water intake, severely diluting serum sodium. With this excessive thirst combined with psychotic symptoms, brain damage such as CPM may result from hyperosmolarity caused by excess intake of fluids, (primary polydipsia) although this is difficult to determine because such patients are often institutionalised and have a long history of mental health conditions. It has been observed following hematopoietic stem cell transplantation. CPM may also occur in patients prone to hyponatraemia affected by: The currently
Serum amyloid A1 regulation of immunity. Serum amyloid A1 Serum amyloid A1 (SAA1) is a protein that in humans is encoded by the "SAA1" gene. SAA1 is a major acute-phase protein mainly produced by hepatocytes in response to infection, tissue injury and malignancy. When released into blood circulation, SAA1 is present as an apolipoprotein associated with high-density lipoprotein (HDL). SAA1 is a major precursor of amyloid A (AA), the deposit of which leads to inflammatory amyloidosis. The gene coding for human SAA1 is one of the 4 SAA genes mapped to a region in the short arm on Chromosome 15. Two of these
