ZHONG-THESIS-2016.Pdf ANTIDEPRESSANTMINING AZ AMAZ DESIGNING A WEBBASED ALGORITHM AND VISUAL LANGUAGE FOR ANTIDEPRESSANT DRUG SELECTION TO EDUCATE PRIMARY CARE PRACTITIONERS By Amy Zhong A thesis submitted to Johns Hopkins University in conformity with the requirements for the degree of Master of Arts Baltimore, Maryland March, 2016 © 2016 Amy Zhong All Rights Reserved ABSTRACT Depression is a common mental disorder that affects approximately 14.8 million American adults each year. In addition to being a debilitating condition, depression often occurs in tandem with other medical conditions such as diabetes, heart disease, and cancer. While psychiatric professionals are essential for the management of mental health, majority of patients seek care from their primary care practitioners. This phenomenon is of great concern because diagnosis of depression within primary care settings has only been accurate 25-50% of the time. The antidepressant drug selection algorithm utilizes a unique formula to integrate patient and family medical histories, patient symptoms, and patient preferences to make optimal treatment selections. The development of a visual language explores the use of graphic elements to improve understanding of major pharmacological mechanisms, knowledge essential to making rational DQWLGHSUHVVDQWGUXJVHOHFWLRQV,QFUHDWLQJWKLVPRELOHZHEEDVHGDSSOLFDWLRQZHKRSHWR¿OOD void in resources available to primary care practitioners, and improve management of mental health within the primary care setting.

In addition to being a chronic mental illness, studies have shown that depression is also a frequent comorbidity of other conditions such as HIV/ AIDS, diabetes, multiple sclerosis, and cancer. Though depression is a treatable condition, it is frequently underdiagnosed and undertreated, and the disease is responsible for a 5-fold increased risk of mortality of comorbid medical conditions (ESC 2015). In 2010, antidepressants were the second most commonly prescribed drug in the US (IMS Health 2011). Between 1988-1994 and 2005-2008 their use increased by 400% (Pratt, et al. 2011). Meanwhile, disturbing evidence shows a steady increase in suicide rates since 2005 with the US suffering nearly 43,000 deaths in 2014 (AFSP 2014). This phenomenon has launched awareness of the increasing involvement of primary care practitioners (PCPs) in mental health – 80% of psychotropic drug prescriptions were made by PCPs in 2013 (Barkil-Oteo 2013) – and the evaluation of their abilities to detect depression and implement the necessary treatment. /LNHRWKHUSV\FKLDWULFGLVRUGHUVGHSUHVVLRQLVDGLI¿FXOWFRQGLWLRQWRUHFRJQL]H'HSUHVVLYH symptoms not only include depressed mood and anhedonia (inability to experience pleasure), but can range from insomnia and anorexia to decreased cognition and suicidal behavior.

The situation, as Dr. Ramin Mojtabai, Associate Professor in the Department of Mental Health at the Johns Hopkins Bloomberg School of Public Health describes, “Without enough time to really talk to patients about depression and with some patients increasingly open to the idea of an antidepressant for mild conditions, the primary care setting can be vulnerable to overprescribing” (Katz 2012).

  • M2021: Pharmacogenetic Testing
    Pharmacogenetic Testing Policy Number: AHS – M2021 – Pharmacogenetic Prior Policy Name and Number, as applicable: Testing • M2021 – Cytochrome P450 Initial Presentation Date: 06/16/2021 Revision Date: N/A I. Policy Description Pharmacogenetics is defined as the study of variability in drug response due to heredity (Nebert, 1999). Cytochrome (CYP) P450 enzymes are a class of enzymes essential in the synthesis and breakdown metabolism of various molecules and chemicals. Found primarily in the liver, these enzymes are also essential for the metabolism of many medications. CYP P450 are essential to produce many biochemical building blocks, such as cholesterol, fatty acids, and bile acids. Additional cytochrome P450 are involved in the metabolism of drugs, carcinogens, and internal substances, such as toxins formed within cells. Mutations in CYP P450 genes can result in the inability to properly metabolize medications and other substances, leading to increased levels of toxic substances in the body. Approximately 58 CYP genes are in humans (Bains, 2013; Tantisira & Weiss, 2019). Thiopurine methyltransferase (TPMT) is an enzyme that methylates azathioprine, mercaptopurine and thioguanine into active thioguanine nucleotide metabolites. Azathioprine and mercaptopurine are used for treatment of nonmalignant immunologic disorders; mercaptopurine is used for treatment of lymphoid malignancies; and thioguanine is used for treatment of myeloid leukemias (Relling et al., 2011). Dihydropyrimidine dehydrogenase (DPD), encoded by the gene DPYD, is a rate-limiting enzyme responsible for fluoropyrimidine catabolism. The fluoropyrimidines (5-fluorouracil and capecitabine) are drugs used in the treatment of solid tumors, such as colorectal, breast, and aerodigestive tract tumors (Amstutz et al., 2018). A variety of cell surface proteins, such as antigen-presenting molecules and other proteins, are encoded by the human leukocyte antigen genes (HLAs).
