Promote Medication Safety and Reduce the Risk of Adverse Drug Events with Pharmacogenomic (PGx) Testing

Adverse drug events (ADEs) are the 4th leading cause of death in the United States, leading to 1.3 million emergency department visits and 350,000 hospitalizations annually.1 Each year, 4.5 million ADEs occur in the US, resulting in $2.5 billion in related healthcare costs.2-4 As many as half of ADEs are considered preventable, yet they continue to pose a serious public health risk with significant financial consequences. As the need to prevent ADEs becomes more dire, there is increased interest in minimizing patient risks.

Healthcare providers often turn to laboratory testing to manage their patients’ medications safely and effectively. For example, a physician might order a test to monitor serum potassium levels for patients taking angiotensin-converting enzyme (ACE) inhibitors or a liver function test (LFT) for a patient on statins.

Pharmacogenomic (PGx) testing is one under-utilized clinical tool that can significantly decrease a patient’s risk of experiencing an ADE. PGx testing identifies genetic variations that affect the structure and function of biological proteins associated with a medication’s absorption, distribution, metabolism, and excretion (ADME). Changes in these proteins functions can affect whether specific drugs are safe and effective for an individual.

PGx testing allows healthcare providers to personalize drug therapy and predict if a medication will be safe, effective, and non-toxic for a patient. Patients with personalized drug therapy based on PGx testing had a 30% lower occurrence of ADEs5 and 6.3% fewer hospitalizations.6 Additionally, PGx testing reduced emergency department and outpatient visits by 11% and 32.5%, respectively.6

Mitigating Adverse Drug Events in Polypharmacy with PGx

What are ADEs and Polypharmacy?

An adverse drug event, or ADE, occurs when a person is harmed due to a prescription medication. This can include known medication side effects or medication errors. About half of ADEs are considered preventable, yet they continue to pose a significant public health risk with substantial financial consequences. Approximately 1.3 million emergency visits1, 350,000 hospitalizations1, and $3.5 billion in excess medical costs2 occur annually in the United States from ADEs. The risk for ADEs increases with each medication a patient is taking, so patients taking multiple medications are at the highest risk for ADEs.

Polypharmacy occurs when a patient simultaneously takes multiple medications to treat one or more conditions. Nearly one third of adults in the United States take five or more medications3. Polypharmacy has become a significant concern in the healthcare industry, as it increases the risk for ADEs and medication failure. In extreme cases, polypharmacy can lead to death. As a result, strategies for decreasing polypharmacy and ADEs are a major focus of patients and healthcare professionals. This article will discuss how Pharmacogenomics (PGX) serves as a tool to help alleviate ADEs.

Who’s at risk?

Patients who are at the highest risk for polypharmacy include those with multiple health conditions, patients with more than one prescriber, and the elderly. In some cases, single conditions have guidelines which state that polypharmacy is a recommended treatment plan after monotherapy fails or underperforms. These conditions include hypertension, type II diabetes, and major depressive disorder. For these conditions, treatment guidelines instruct healthcare providers to add additional medications to a patient’s treatment plan when the first is inadequate. In some cases, healthcare providers may prescribe additional medications to treat the side effects of another drug. For example, a provider may prescribe an anti-nausea medication for a patient who experiences nausea as a side effect of codeine.

PGx – A Tool to Reduce ADEs and Polypharmacy

Laboratory testing is one of the most frequently used clinical tools to help providers safely and effectively manage their patients’ medications. Research shows that optimal usage of laboratory tests can decrease a patient’s risk of experiencing an ADE4. For example, a physician might order a test to monitor serum potassium levels for patients taking angiotensin-converting enzyme (ACE) inhibitors or a liver function test (LFT) for a patient on statins.

Pharmacogenomics (PGx) testing is one less frequently used clinical tool that can significantly decrease the risk of ADEs. PGx testing identifies variants in a patient’s DNA that affect how well that person responds to specific medications. PGx can help predict if a drug will be safe, effective, and non-toxic for a patient. The PGx test reduces the need for trial-and-error prescribing. Preemptive PGx testing is especially beneficial because it assists a prescriber in identifying a patient’s risk of experiencing an ADE before the medication is prescribed.

With PGx testing, a prescriber can make informed decisions that decrease the risk of polypharmacy. When a provider knows that a patient is more likely to have side effects from a medication, they can prescribe an alternative. Doing so eliminates the need for additional medications to treat the side effects of the first. A provider can also use PGx information to select a drug that is more likely to be effective for the patient. This reduces the risk of medication failure and makes it less likely that the provider will need to prescribe a second medication to treat the patient’s condition.

A Reproducible Method for Assessing the Effects of Blue Light Using in vitro Human Skin Tissues

Genemarkers LLC is pleased to announce the publication of the paper, Reproducible method for assessing the effects of blue light using in vitro human skin tissues, in the International Journal of Cosmetic Science.

High-intensity visible light (HEV), also known as blue light, accounts for approximately one-third of visible light. Electronic devices and artificial lighting are top emitters of blue light. Previous research has established that exposure to blue light for periods as short as 1 hour can have detrimental effects on the skin. Blue light exposure can increase reactive oxygen species (ROS), apoptosis, and necrosis. Although the damaging effects of blue light are well-established, the ability to study the impact of blue light on human skin has been limited by a lack of suitable in vitro testing methods. Genemarkers’ research bridges this gap.

Using a full-thickness, 3D, in vitro skin tissue model, Genemarkers used varying exposures of blue light to determine the biological effects on human skin. This work demonstrated that daily exposure to blue light produced dose-and-time-dependent changes in the genes associated with skin damage.

The study found that exposure to blue light increased the expression of genes that regulate inflammation and oxidative stress and decreased the expression of genes maintaining the skin barrier and tissue integrity. Exposure significantly increased biomarkers associated with aging and tissue damage. Treatment with ascorbic acid inhibited the effects of blue light, suggesting that topical antioxidants can protect the skin from the deleterious effects of blue light.

As a result of this work, Genemarkers has launched a new blue light testing service that includes a gene expression panel containing 52 genes specifically impacted by blue light; the genes regulate biological pathways such as oxidative stress, inflammation, and skin aging. This service enables Genemarkers’ clients to assess how their products protect against and repair damage caused by the skin’s exposure to blue light.
