With two impending clinical trials, Valley Fever Awareness Week, celebrated Nov. 7-15 in Arizona, is bigger than ever this year.
In fact, activities for the 13th annual observance — held by proclamation of the Arizona Governor’s Office since 2003 — have grown beyond the official second week in November with free presentations for the public and health professionals in Tucson and Phoenix scheduled from Oct. 24 to Nov. 18.
The More You Know, the Better
“You can’t prevent Valley Fever, but it’s important the public know about this disease largely of the lungs so they can ask their doctor when they get sick whether or not it’s Valley Fever,” said John N. Galgiani, MD, a University of Arizona professor of medicine and founding director of the UA Valley Fever Center for Excellence. “A third of all pneumonia cases in Phoenix and Tucson are caused by Valley Fever, but doctors often may forget to look for it. They’re more likely to do that if patients also know about this possibility and remind them.”
Common to the U.S. Southwest and Northwest Mexico, Valley Fever is caused by the Coccidioides species of fungus, which grows in soils in areas of low rainfall, high summer temperatures and moderate winter temperatures. These fungal spores become airborne when soil is disturbed by winds, construction, farming, gardening and other activities. In people and animals, infection occurs when a spore is inhaled. Most exposed people never show symptoms. In those who do, the symptoms resemble those of pneumonia, including cough, chills and chest pain as well as fatigue, fever, headaches and night sweats. Skin rashes or lumps also may occur.
Most people suffering from Valley Fever recover in a few weeks or months. Of the approximately 150,000 U.S. Valley Fever infections that occur per year, however, about 160 people die. Two-thirds of these infections affect Arizonans, mostly in the “Valley Fever Corridor” that runs between the state’s two largest cities of Phoenix and Tucson. Pets, especially dogs, also are susceptible to Valley Fever.
Valley Fever Awareness Week events provide opportunities to hear experts and ask questions about the illness known as Coccidioidomycosis.
Infectious Disease Threats
Physicians can get an early preview with Dr. Galgiani’s “Coccidioidomycosis Update” lecture on Saturday, Oct. 24, 12:30 to 1:30 p.m., at the 4th Annual Southwestern Conference on Medicine. The Tucson Osteopathic Medical Foundation event, whose theme is “Infectious Disease Threats in Primary Care,” will be hosted at the Tucson Osteopathic Medical Foundation Conference Center, 3182 N. Swan Road, Tucson. Register at www.tomf.org/cme
Dr. Galgiani will discuss the UA Valley Fever Center for Excellence’s participation in clinical trials about to start for a National Institutes of Health-funded study for which Duke University’s Human Vaccine Institute was awarded a $5 million contract in June to support research into Valley Fever pneumonia. That funding could grow to $9 million if all contract options are explored.
“We’re working with Duke as an enrollment site both in Tucson and Phoenix at the Banner – University Medical Centers,” Dr. Galgiani said. “It also involves study sites in California’s Central Valley.”
Meanwhile, the UA Valley Fever Center for Excellence continues pressing forward on efforts to get a potentially curative anti-Valley Fever drug, nikkomycin Z (NikZ), into clinical trials. Those efforts got a boost last October when NikZ won fast-track designation by the U.S. Food and Drug Administration as a “qualifying infectious disease product” (QIDP). The UA has been helping to move the antifungal drug into clinical trials and eventually to help patients. It licensed development rights for NikZ to Valley Fever Solutions, Inc., a small start-up business in Tucson.
Animals Get It, Too
The plan, Dr. Galgiani said, is to start clinical trials with dogs first and move to humans later. “Dogs get Valley Fever just like humans and even more commonly.”
Lisa Shubitz, DVM, an associate research professor in the UA School of Animal & Comparative Biomedical Sciences who works on the Valley Fever vaccine project, said Valley Fever in animals is a huge problem, with costs affecting dogs alone estimated at about $60 million a year in Arizona. The center isn’t quite ready to begin canine trials.
“We’ve completed some studies and have another about to start looking at how long mice stay immune,” Dr. Shubitz said. “So far, it’s up to six months. We’re looking to find out at what point the efficacy drops off. That study won’t be completed until next spring.”
Events Open to the Public
The public is invited to participate in six Valley Fever Awareness Week events, two in the Phoenix area, three in Tucson and one in Cottonwood, Ariz.:
