Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it. Scarring alopecia plaquenil or hydroxychloroquine Chloroquine proguanil Chloroquine blocks MHC class II‐restricted endogenous antigen presentation by SaI/A k /HEL vaccines. Antigen‐presenting cells, TA3, EL‐4/ova or SaI/A k /HEL, were treated with chloroquine and incubated with 3A9 TA3 and SaI/A k /HEL or B3Z EL‐4/ova hybridoma cells. Chloroquine and its congeners can cause two typical adverse effects in the eyes keratopathy and retinopathy. Both of these effects are associated with the administration of the drugs over long periods of time. Chloroquine-induced keratopathy is limited to the corneal epithelium, where high concentrations of the drug are usually used. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. Occasionally it is used for amebiasis that is occurring outside the intestines, rheumatoid arthritis, and lupus erythematosus. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

On day 3 of chloroquine therapy, she developed localized brisk bullous eruptions in the irradiated area, which developed into a patch of fulminant moist desquamation. After radiotherapy was withheld for 1 week, the moist desquamation had almost healed. The major histocompatibility complex MHC is a principal susceptibility locus for many human autoimmune diseases, in which self-tissue antigens providing targets for pathogenic lymphocytes are bound to HLA molecules encoded by disease-associated alleles. GVHD, including inhibition of major histocompatibility complex MHC class II antigen presentation, cytokine production, and antigen-presenting cell activation by bacterially derived CpG oligodeoxynucleotides ODNs. Using an MHC-disparate murine model, we evaluated the effect of chloroquine treatment on the development of acute GVHD.
