What are anti rejection drugs and why are they used?

Do you know what a kidney is? Of course, you do. It’s that bean-shaped organ in your body responsible for filtering your blood so that all the bad stuff can be peed out of your system. Pretty amazing, right? Now imagine if one day it just decided to go on strike and leave you high and dry (or rather wet, considering all the fluids build up as waste). That would not be funny at all.

Sadly, this is a reality for many people with kidney failure. When the kidneys fail to function properly or cease functioning altogether, they need help from external sources like dialysis or even transplantation. The latter involves replacing dysfunctional kidneys with healthy ones from donors (living or deceased), which sounds like a miracle solution until the recipient’s immune system decides to reject it mercilessly.

This is where anti-rejection drugs come into play – these are medications used after an organ transplant to keep the recipient’s immune system from attacking the new organ as a foreign invader.

Understanding Organ Transplantation

Before we dive too deep into what anti-rejection drugs are and how they work their magic on our bodies’ systems let us first understand how transplantation works:

Organ transplantation refers to surgically removing an organ/tissue from one person (donor) and transferring/transplanting it into another person who has non-functional organs due to disease or injury (recipient). In other words; receiving some else’s functioning parts by suturing them in! Incredible isn’t it?

We may have heard of different types of transplant procedures like liver transplants cortical implants but did you know there are multifarious things that come along during transplant surgery except excising diseased areas – hand-eye coordination while acquiring replacement components/ applying modern techniques involving lasers etc… oh wait not everyone chooses laser treatment!

Now just because two individuals share similar blood groups doesn’t mean they have similar human leukocyte antigens (HLA). The closer a donor and recipient’s HLA, the higher their compatibility would be.

All sounds good but once an Organ transplant surgery carries out there is always a risk of organ rejection from our immune system which helps to keep us healthy against germs. As much as this sound altruistic it can also backfire when we start seeing what we see after organ transplant surgeries

What is Rejection?

It’s not just edgy teenagers who enjoy rejecting everything they come across – bodies do too. When something like an external object enters your body that isn’t recognised as “self”, the general response is for your immune system to attack and attempt to eliminate whatever it perceives as harmful invaders before they cause damage! It’s just doing its job – Saving you!

The problem with organs in transplants is that even though they are freshly harvested without any infections, bacteria or viruses due to lack of matching HLAs some parts may be recognised by our mortal immunity fighters (Yes I meant Immune System), meaning that antibodies created could identify grafted tissues/organs/limbs wrongly; causing significant harm (I’m Talking Maleficent Style here)!

Rejection leads to various types depending on how long has elapsed since transplantation: Hyperacute Rejection Occurs within minutes! Once Anatomic changes become obvious? One might have difficulty detecting Acute Cellular /Humoral among other forms

Pulling Back Let’s pause for now and let me give examples illustrating why are anti-rejections drugs necessary;

  1. You got into a horrible accident resulting loss of limbs hence putting you at life-long bed rest/ reliance on machine assistance.
  2. You may have gotten alcoholic cirrhosis later discovered needed liver transtuesnt
    3.And After years of peaceful married life despite having health issues all along, 70-year-old George finally gets his kidneys replaced through kidney renal replacement therapy

Great Examples You may say but in simple terms, transplant surgery exists for those with serious organ failure! Sure missing a few areas isn’t ideal could inhibit you from partying healthy or life athletic events lasting longer than your usual 40 mins. Still, transplant therapy augments the quality of living as well as lifespan!

The Antirejection Drugs

Now that we know what rejection is and why it’s bad news let’s talk about how antirejection drugs work their magic.

The aim of anti-rejection medicines is to suppress the immune system to stop antibodies’ creation-proliferation without attacking foreign objects like newly attached organs/limbs/extremities. Different categories/groups exist under Anti-rejections Meds such as Corticosteroids, Antimicrobials miscellaneous immuno-suppressants this cocktail limits body immunity making sure no erroneous attacks occur on grafted functions so they can continue to function optimally!.

Despite helping with acceptance of dependent objects, immunosuppression leads to an increased risk of infections since diminished Immune Surveillance potentially leading to many ridiculous health issues ranging from mild common cold influenza chickenpox etc… yes laughable until you get one yourself (Not Fun)

Organ transplantation industry has relied heavily on developing versatile stand-alone drugs that would reduce the side effects caused by these dangerous/insidious medication’s/life-saving drugs.

Types Of Medications Used In Transplantation:

There are numerous types/categories for Clinicians below discussed options;

1. Calcineurin inhibitors (CNIs)

Calcineurin inhibitors suppress T-cells which cause rejection in transplant patients; by inducing cell division arrest regulate t-cells proliferation morpholines/tacrolimus have decreased toxicity levels/(to name a few).

2.Antimetabolites

This drug category acted against cells right before replication occurs substances like Mycophenolate Mofetil and Azathioprine are the most well-known representatives. This class should be used when steroid side effects get worse or Calcineurin inhibitors have to leave.

3.Corticosteroids

This drug class is highly effective for reducing cancer/new organ warning sides Gratefully reduces inflammation by suppressing the immune system/hinders Fibrosis which can lead to greater complications Examples are Betamethasone, Methylprednisolone).

Parting Words

While anti-rejection medicines pave the way for recipients’ successful acceptance of new organs/life-extending functions; it should always be kept in mind you need to be responsible while under treatment with them as they bring their own unique challenges (like weakened immunity/ infection risks etc) To wrap things up make sure if planning or already undergone transplant surgery attention/specialists care is a must!).Never self medicate and follow prescriptions religiously also listen closely to doctors notes! Cheers!
