Cholinesterase activity in the low density lipoprotein fraction of serum is increased in types IIa, IIb and IV hyperlipoproteinemic patients, whereas only types IIb and IV show increases in serum cholinesterase activity. In obese patients, cholinesterase activity is increased both in the serum and low density lipoprotein fraction only when hyperlipidemia is present. Cholinesterase activity is also found to increase in proportion with increases in low density lipoprotein, cholesterol, and triglycerides both in the serum and low density lipoprotein fraction. We suggest on the basis of these findings that cholinesterase has a function in lipid and lipoprotein metabolism.

Paraoxonase activities (322 healthy subjects) measured in the absence of ethylenediaminetetraacetic acid (EDTA) had a polymodal distribution profile with 60% of the subjects in the low activity mode; the activity measured in the presence of EDTA had a unimodal skewed distribution. Cholinesterase (ChE) activities (365 healthy subjects) had a unimodal, slightly skewed distribution. Patients with dementia (74) and patients with hyperlipidaemia (159) had different median paraoxonase and ChE activities than healthy subjects and all activity profiles had a higher skewness. The ChE variants usual (UU), fluoride resistant (FS) and atypical (AA) had the same affinity for the studied charged and uncharged ligands. The variants differed in rates of inhibition by the charged organophosphates and carbamates.

Alzheimer's disease (AD) is the most common cause of dementia affecting nearly 18 million people around the world and 4.5 million in the US. It is a progressive neurodegenerative condition that is estimated to dramatically increase in prevalence as the elderly population continues to grow. As the cognitive and neuropsychiatric signs and symptoms of AD progresses in severity over time, affected individuals become increasingly dependent on others for assistance in performing all activities of daily living. The burden of caring for someone affected by the disorder is great and has substantial impact on a family's emotional, social and financial well-being. In the US, the currently approved medications for the treatment of mild to moderate stages of AD are the cholinesterase inhibitors (ChEIs). Cholinesterase inhibitors have shown modest efficacy in terms of symptomatic improvement and stabilization for periods generally ranging from 6 to 12 months. There are additional data that have emerged, which suggest longer-term benefits. For the moderate to severe stages of AD, memantine, an N-methyl-D-aspartate (NMDA) receptor antagonist is in widespread use and has shown modest benefit as monotherapy and in combination with ChEIs. The cost effectiveness of the currently available therapeutic agents for AD has undergone great scrutiny and remains controversial, especially outside the US. Neuropsychiatric symptoms such as agitation and psychosis are common in AD. Unfortunately, in the US there are no Food and Drug Administration (FDA)-approved agents for the treatment of these symptoms, although atypical antipsychotics have shown some efficacy and have been widely used. However, the use of these agents has recently warranted special caution due to reports of associated adverse effects such as weight gain, hyperlipidemia, glucose intolerance, cerebrovascular events, and an increased risk for death. Alternative agents used to treat neuropsychiatric symptoms include serotonergic antidepressants, benzodiazepines, and anticonvulsant medications.
