Itraconazole, sometimes abbreviated ITZ, is an antifungal medication used to treat a number of fungal infections. This includes aspergillosis, blastomycosis, coccidioidomycosis, histoplasmosis, and paracoccidioidomycosis. It may be given by mouth or intravenously.Common side effects include nausea, diarrhea, abdominal pain, rash, and headache. Severe side effects may include liver problems, heart failure, Stevens–Johnson syndrome and allergic reactions including anaphylaxis. It is unclear if use during pregnancy or breastfeeding is safe. It is in the triazole family of medications. It stops fungal growth by affecting the cell membrane or affecting their metabolism.Itraconazole was patented in 1978 and approved for medical use in the United States in 1992. It is on the World Health Organizations List of Essential Medicines.Recent research works suggest itraconazole (ITZ) could also be used in the treatment of cancer by inhibiting the hedgehog pathway in a similar way to sonidegib. Medical uses
Itraconazole has a broader spectrum of activity than fluconazole (but not as broad as voriconazole or posaconazole). In particular, it is active against Aspergillus, which fluconazole is not. It is also licensed for use in blastomycosis, sporotrichosis, histoplasmosis, and onychomycosis. Itraconazole is over 99% protein-bound and has virtually no penetration into cerebrospinal fluid. Therefore, it should not be used to treat meningitis or other central nervous system infections. According to the Johns Hopkins Abx Guide, it has "negligible CSF penetration, however treatment has been successful for cryptococcal and coccidioidal meningitis".It is also prescribed for systemic infections, such as aspergillosis, candidiasis, and cryptococcosis, where other antifungal drugs are inappropriate or ineffective.
Treatment
Treatment for juvenile hemochromatosis is similar to that for other forms of hemochromatosis and iron overload, and focuses on reducing the amount of iron in the body in order to prevent complications of iron overload. However, if the disease is not discovered early enough, or if progress is not well controlled, further treatments may be aimed at the symptoms of organ damage which may develop. Phlebotomy
Phlebotomy, the removal of blood from the body, is the main treatment for juvenile hemochromatosis. One unit of blood, the amount typically given during blood donation, is typically removed per session, and it is generally recommended that this be done once weekly until acceptable levels of iron are in the blood, which may take years. After these levels are reached, phlebotomy will be continued, but less often than once weekly, perhaps every few months. Chelation Therapy
In the event that phlebotomy is not an appropriate option or is not enough on its own to reduce iron levels, chelation medications, those that bind and remove certain metals from the blood, may be utilized. Examples of chelators specifically for iron include deferoxamine and deferasirox. Dietary Modification
It is recommended that those with juvenile hemochromatosis refrain from eating iron supplements, vitamin C supplements, and uncooked/undercooked seafood and shellfish, and reduce or eliminate consumption of alcoholic beverages and red meat. Additional Treatments
If the disease is advanced enough, further treatments can be aimed at the complications of the disease, depending on which are present:
Diabetes may be treated with oral medications and/or insulin as indicated.
