A woman who is Rh negative has two children, both of whom are Rh positive. The pregnancy with her first child posed no problem. But why is her second pregnancy potentially dangerous?

Answers

Answer 1

Rh sensitization can occur during pregnancy if you are Rh-negative and pregnant with a developing baby (fetus) who has Rh-positive blood. In most cases, your blood will not mix with your baby's blood until delivery. It takes a while to make antibodies that can affect the baby, so during your first pregnancy, the baby probably would not be affected.
But if you get pregnant again with an Rh-positive baby, the antibodies already in your blood could attack the baby's red blood cells. This can cause the baby to have anemia, jaundice, or more serious problems. This is called Rh disease. The problems will tend to get worse with each Rh-positive pregnancy you have.

The correct options that are true about disease modulating agents are:

Disease modulating medications reduce the frequency and severity of exacerbations, There are 5 drugs approved by the U.S. FDA to modify the progression of the disease, Disease modulating medications can carry significant health risks.

1. Disease modulating medications reduce the frequency and severity of exacerbations: Disease-modifying agents used in the treatment of multiple sclerosis (MS) have shown efficacy in reducing the frequency and severity of relapses or exacerbations. These medications work by targeting the underlying immune processes and inflammation associated with MS, helping to slow disease progression and mitigate relapse activity.

2. There are 5 drugs approved by the U.S. FDA to modify the progression of the disease: As of my knowledge cutoff in September 2021, there were five disease-modifying drugs approved by the U.S. FDA for the treatment of multiple sclerosis. These drugs include interferon beta-1a, interferon beta-1b, glatiramer acetate, teriflunomide, and dimethyl fumarate. Each of these medications has demonstrated effectiveness in reducing disease activity and modifying the course of MS.

3. Disease modulating medications can carry significant health risks: While disease-modifying agents have proven benefits, it is important to note that they can also carry significant health risks. These risks vary depending on the specific medication but may include side effects such as injection site reactions, flu-like symptoms, liver abnormalities, cardiovascular risks, or potential for serious infections. It is crucial for healthcare providers to carefully monitor patients receiving these medications and weigh the potential risks against the benefits on an individual basis.
