The Influence of Plaquenil/Hydroxychloroquine (HCQ) on Insulin Secretion

2016-09-21 20:23:21 | BioPortfolio

Summary

Antimalarials such as hydroxychloroquine (HCQ), are among the oldest prescribed drugs still used in clinical practice. Relatively inexpensive and well tolerated, these drugs have been recognized to be effective in autoimmune diseases such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Interestingly, there is growing evidence of their beneficial impact on cardiovascular risk, particularly diabetes. HCQ therapy can improve balance in patients with unbalanced diabetes. This drug therapy may be a new therapeutic approach for diabetes. There is need for a better understanding of the mechanisms responsible for the improvement of the metabolic response to drug treatment. The investigators hypothesize that treatment with a drug improves the function of the beta cell and its ability to secrete insulin in response to glucose. The investigators will examine the impact of short-term therapy for HCQ in beta cell function in healthy volunteers and in patients with type 2 diabetes.

Medical and Biotech [MESH] Definitions

The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

A chemotherapeutic agent that acts against erythrocytic forms of malarial parasites. Hydroxychloroquine appears to concentrate in food vacuoles of affected protozoa. It inhibits plasmodial heme polymerase. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 9th ed, p970)

A severe type of hyperlipidemia, sometimes familial, that it is characterized by the elevation of both plasma CHYLOMICRONS and TRIGLYCERIDES contained in VERY-LOW-DENSITY LIPOPROTEINS. Type V hyperlipoproteinemia is often associated with DIABETES MELLITUS and is not caused by reduced LIPOPROTEIN LIPASE activity as in HYPERLIPOPROTEINEMIA TYPE I .

Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).
