Why immunosuppressive drugs after a transplant?

So you’ve just undergone a transplant and are now faced with the daunting prospect of taking immunosuppressive drugs for the rest of your life. Don’t worry, it’s not as bad as it seems! Here’s all you need to know about why it’s necessary for transplant patients to take immunosuppressants.

The Basics

First things first – what exactly are immunosuppressive drugs? Simply put, they’re medications that weaken or suppress the immune system. In normal circumstances, our immune system works tirelessly to protect us from infections and illnesses by attacking foreign substances like viruses and bacteria. However, after a transplant surgery, the new organ is seen as a foreign body by your immune system which can trigger an attack on this ‘invader.’ Immunocompromised individuals such as Transplant patients take these immunosuppessive drugs in order to prevent attacks on their transplanted organs.

Risks Involved in Not Taking Immunosuppressives

Now you might be thinking – “What could happen if I don’t take them?” Well dear reader here’s something that will definitely make you say WoW – Without immunosuppessive medication following transplantation there is high probability that one’s body will reject the transplanted organ resulting in some very severe consequences including but not limited to sepsis (life-threatening bacterial infection), injury or even loss of function of allografts which simply means somebody else’s tissue/organ that is transplanted into another person.

How do They Work?

Immunosuppressive medications work in various ways depending on their type; however most of them target T-cells which play key role in the inflammatory response initiated during inflammation processes also responsible for rejecting donor organs. These essential cells (T-cells) fight against foreign agents including newly-transplanted organs. The medication’s objective is to prevent the immune system from recognizing the transplanted organ as a foreign body that must be attacked; thus, reducing its overall effectiveness for fighting infections.

Common types of immunosuppressive drugs

There are several types of immunosuppressive pharmacology regimens available, and here are some examples:

Corticosteroids

Corticosteroids have been utilized since 1940s for their anti-inflammatory effects. Typical agents include prednisone and methylprednisolone which work by suppressing your immune response via multiple pathways affecting T-cells, B-lymphocytes macrophages amongst others leading to suppression/reduction in cytokine/chemokine production (inflammation inducing molecules) that would normally direct an attack on transplant organs.

Calcineurin Inhibitors

Calcineurin inhibitors such as cyclosporine (Sandimmune®, Gengraf®), tacrolimus (Prograf®) regulate nutrient signalling in cells thus interrupting signals essential for activation of lymphocyte proliferation thereby inhibiting transcription factors like Nuclear Factor Of Activated T-Cells resulting into cell cycle arrest,respiratory burst abrogation etc,this suppresses inflammation responsible for rejection reaction.

Anti-proliferative Drugs

Antiproliferative drugs including such azathioprine Imuran™ methotrexate Trexall ™ mycophenolate CellCept™ result in decreased number of immune cells mainly T -cells due to interfering with DNA synthesis leading to ineffective replication within these essential players usually promoted during transplant rejection reactions

How long do I need to take them?

Follow-up care after transplantation typically involves regular clinic visits if not home-based monitoring but generally you will need these medications indefinitely. Typically,your medical staff determines doses administered based among other things individual patient circumstances including age/type/kind of allograft used, general health of the recipient both pre and post transplant periods as well availability/compliance to other possible supportive therapies such as diet/lifestyle modifications etc.

Are there any side effects?

Yes! all medications have potential adverse events/side effects that arise in a certain percentage of patients usually short lived ranging from headache to life threatening adverse events. it is important that you remain under supervision during your follow-up clinic visits for thorough surveillance and resolution where applicable should they occur.

Potential Short-term Side Effects:

  • Nausea vomiting
  • Diarrhea
  • heartburn/acid reflux due to gastroesophageal reflex disorder or GORD,
  • weight gain/increased appetite confusion/hallucinations in elderly especially those on high dose corticosteroids.

Elevated blood pressure can also occur commonly with calcineurin inhibitors like cyclosporine – this occurs regularly thus regular assessment/review by healthcare specialists will be necessary.where long term use is required different complications may result.

This being said some of these same side affects form part os immunosuppressant utility when used responsibly such suppression of immune system has led to increased risk for atypical infections necessitate precautionary measures against sources/breeding foci of such microorganisms including careful home hygiene avoiding raw/uncooked meat/water sources amongst others.

Resuming Normal Life

Once you’ve been started on immunosuppressive drugs and your medical team deems time suitable,prioritized activities allowing bearing minimal strain/cost e.g walking within safe limits, light stretching exercises/swimming ,others include resumption work/home related duties strictly under supervision.

Additional Support Therapies

You should expect additional supportive therapy advice beyond medication,dietician/nutrition support pulmonary/cardiac etc according individual needs following evaluation.
