Elizabeth Unger

Elizabeth (Beth) R. Unger, MD, PhD, is the Chief of the Chronic Viral Disease Branch (CVDB), Division of High-Consequence Pathogens and Pathology, National Center for Emerging and Zoonotic Infectious Diseases at the Centers for Disease Control & Prevention, Atlanta, Georgia. Chronic fatigue syndrome research falls under her department. She has worked at the CDC since 1997 and replaced Dr. William Reeves as Chief of CVDB in 2010. Dr. Unger has done extensive research at the CDC on the Human papillomavirus (HPV).

In 2005, the CDC published a study where they concluded that the 1994 CDC case definition (known as the empirical definition, Fukuda criteria, or the Reeves criteria) of CFS "identifies persons with CFS in a precise manner that can be readily reproduced by both investigators and clinicians." This study garnered much criticism from the patient community for not being specific enough to exclude patients which other illnesses. In particular, there is no mention of post-exertional malaise. Dr. Unger is listed as one of the ten authors.

Education
Dr. Unger received an undergraduate degree in Chemistry at Lebanon Valley College, Annville, PA and her PhD and MD in the Division of Biologic Sciences at the University of Chicago. Her residency and fellowship was completed at Pennsylvania State University Medical Center.

 * 2015, Pathway-focused genetic evaluation of immune and inflammation related genes with chronic fatigue syndrome."ABSTRACT: '...This study was done to explore the association of functionally important genetic variants in inflammation and immune pathways with CFS. Peripheral blood DNA was isolated from 50 CFS and 121 non-fatigued (NF) control participants in a population-based study...CFS was associated with 32 functionally important SNPs: 11 missense variants, 4 synonymous variants, 11 untranslated regulatory region (UTR) variants and 6 intronic variants. Some of these SNPs were in genes within pathways related to complement cascade (SERPINA5, CFB, CFH, MASP1 and C6), chemokines (CXCL16, CCR4, CCL27), cytokine signaling (IL18, IL17B, IL2RB), and toll-like receptor signaling (TIRAP, IRAK4). Of particular interest is association of CFS with two missense variants in genes of complement activation, rs4151667 (L9H) in CFB and rs1061170 (Y402H) in CFH...'"
 * 2015, Early menopause and other gynecologic risk indicators for chronic fatigue syndrome in women."ABSTRACT: '...84 CFS cases and 73 healthy controls...Cases and controls were of similar age. Women with CFS reported significantly more gynecologic conditions and surgical operations than controls...Menstrual abnormalities, endometriosis, pelvic pain, hysterectomy, and early/surgical menopause are all associated with CFS. Clinicians should be aware of the association between common gynecologic problems and CFS in women. Further work is warranted to determine whether these conditions contribute to the development and/or perpetuation of CFS in some women.'"
