Complete the following discussions: Identify a drug produced by rDNA technology, other than the drugs listed in your textbook. Describe the illness it is used to treat. In your opinion, should this technology be used to treat patients? Why or why not? Search the Internet and review your state’s regulations for newborn screening. Determine the number and types of tests being performed in your state. In your opinion, should all states be mandated to screen for all disorders that newborn screening detects? Why or why not?
Discussion 1: Drug produced by rDNA technology
One example of a drug produced by recombinant DNA (rDNA) technology is insulin. Insulin is a hormone produced by the pancreas that plays a vital role in regulating blood sugar levels. Individuals with diabetes either do not produce enough insulin (Type 1 diabetes) or are unable to use insulin effectively (Type 2 diabetes). Insulin therapy is the mainstay of treatment for diabetes and is essential for maintaining normal blood glucose levels.
rDNA technology enables the production of human insulin in large quantities. Previously, insulin was derived from animal sources, particularly pigs and cows. However, the use of animal-derived insulin had limitations, including the potential for allergic reactions and inconsistent quality. With the advent of rDNA technology, human insulin can be produced in bacteria or yeast cells, ensuring a safer and more reliable source of the hormone.
Insulin produced through rDNA technology has revolutionized diabetes care by providing a more effective and accessible treatment option. It allows for precise control of insulin dosing, leading to better glycemic control and reducing the risk of complications associated with diabetes. Moreover, the availability of recombinant insulin has improved the lives of individuals with diabetes by eliminating the need for regular injections of animal-derived insulin.
In my opinion, rDNA technology should definitely be used to produce insulin and treat patients with diabetes. The benefits of using recombinant insulin far outweigh any potential drawbacks. By utilizing this technology, insulin can be produced at a larger scale, ensuring a stable supply for patients worldwide. Moreover, the use of human insulin reduces the risk of allergic reactions and ensures consistent quality and purity.
Discussion 2: Newborn screening and its regulation
Newborn screening is a critical public health program that aims to identify infants at risk of certain genetic conditions or disorders shortly after birth. These disorders may not be apparent at birth, but early detection and intervention can greatly improve outcomes for affected infants. Each state in the United States has its own regulations and guidelines for newborn screening.
The number and types of tests conducted in newborn screening programs differ between states. However, some common conditions screened for include phenylketonuria (PKU), hypothyroidism, sickle cell disease, cystic fibrosis, and congenital hearing loss. These tests typically involve collecting a small blood sample from the newborn to screen for specific genetic markers or abnormalities.
In my opinion, it is essential that all states are mandated to screen for all disorders that newborn screening detects. Early detection of these conditions allows for prompt intervention and the implementation of appropriate treatment strategies. Many of these disorders, if left untreated, can lead to severe health problems and lifelong disabilities. Newborn screening serves as a crucial tool for identifying these conditions early on, providing infants with a better chance of leading healthy lives.
Furthermore, by mandating consistent screening protocols across all states, we ensure equal access to early detection and intervention for all newborns. This approach helps prevent disparities in healthcare access and ensures that every child has the opportunity to receive timely and appropriate care.
However, it is important to consider ethical considerations and the potential risks associated with expanding newborn screening programs. Such considerations include ensuring parental consent and understanding the implications of positive screening results. Additionally, there is a need for ongoing evaluation of the cost-effectiveness and feasibility of implementing additional screening tests.
In conclusion, rDNA technology has paved the way for the production of drugs like insulin, enabling more effective treatments for various illnesses. It is crucial to incorporate this technology into healthcare practices. Similarly, expanding newborn screening programs to include all detectable disorders across all states is essential for early intervention and equitable healthcare access for all infants.
