Hydroxychloroquine and Unexplained Recurrent Miscarriage

2020-01-21 11:32:37 | BioPortfolio


Recurrent miscarriage affects women of childbearing age worldwide. Vascular endothelial dysfunction and immunological impairment are associated with both recurrent miscarriage and preeclampsia. To date, there is no effective or optimal therapeutic approach for these conditions. Hydroxychloroquine has endothelial protective action via ant diabetic, lipid lowering, antioxidant effects or direct endothelial protection. Hydroxychloroquine is an antimalarial and immunomodulatory agent. In pregnancy, hydroxychloroquine is prescribed for inflammatory conditions associated with adverse perinatal outcomes such as systemic lupus erythematosus, antiphospholipid syndrome and placental inflammatory lesions such as chronic histiocytic intervillositis, hydroxychloroquine has therapeutic potential to improve placental function in pregnancies associated with heightened inflammation.

Medical and Biotech [MESH] Definitions

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)

The active metabolite of FOLIC ACID. Leucovorin is used principally as its calcium salt as an antidote to folic acid antagonists which block the conversion of folic acid to folinic acid.

An immunosuppressive agent used in combination with cyclophosphamide and hydroxychloroquine in the treatment of rheumatoid arthritis. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), this substance has been listed as a known carcinogen. (Merck Index, 11th ed)

Cell surface receptors that bind to and transport FOLIC ACID, 5-methyltetrahydrofolate, and a variety of folic acid derivatives. The receptors are essential for normal NEURAL TUBE development and transport folic acid via receptor-mediated endocytosis.

Derivatives of folic acid (pteroylglutamic acid). In gamma-glutamyl linkage they are found in many tissues. They are converted to folic acid by the action of pteroylpolyglutamate hydrolase or synthesized from folic acid by the action of folate polyglutamate synthetase. Synthetic pteroylpolyglutamic acids, which are in alpha-glutamyl linkage, are active in bacterial growth assays.
