Shingles and Organ Transplant

A microorganism that cannot grow or reproduce apart or replicate from a living cell is called a virus. This microorganism has many types. It can be made from either DNA or RNA.

What is Herpes Zoster?

Herpes zoster, more commonly called shingles, is a viral skin infection caused by a member of a group of DNA viruses known as Varicella zoster virus, also called herpes zoster virus. This is the same etiologic agent for chickenpox. Shingles is characterized by an eruption of painful vesicles from one or more posterior ganglia along the area of distribution of the sensory nerves. There are two common terms of herpes zoster depending on the rashes’ distribution. Herpes zoster oticus involves the ear while herpes zoster ophthalmicus involves the orbit of the eye.

The Risk Factors

Shingles or herpes zoster will not exist without the presence of risk factors or contributing factors which can affect a person. These factors include previous history of chickenpox, an age of 50 years and above, and/or a weakened immune system caused by HIV/AIDS, cancer or cancer treatments. Examples of such treatment modalities for cancer are radiation and chemotherapy, prolonged use of steroids such as prednisone, and medications designed to prevent rejection of transplanted organs.

Organ transplant can contribute to the development of shingles. The main one at risk in an organ transplant from shingles is the organ transplant recipient or the one who receives the organ to be transplanted.

What is Organ Transplant?

Let us know more about organ transplant. It is a medical procedure which occurs by moving an organ or tissue from one body to another.

Types of Organ Transplant

This procedure has many types. Autograft is the transplantation of a tissue or an organ to the same person which means the donor and the recipient is the same. Allograft is the transplantation of a tissue or an organ between two of the same species but is not genetically identical. Isograft is the transplantation of a tissue or an organ between two the same species but is genetically identical such as an identical twin.

Xenograft is the transplantation of a tissue or an organ between one species to another. Split transplant, not usually a preferred option, is the transplantation of a tissue or an organ from a deceased donor that can be divided between two recipients.

Classification of the Body

An organ transplant is only done to the body’s replaceable parts. There are three classes of transplantable organs. Thoracic organs include the heart, lung, and heart. Abdominal organs consist of the kidney, liver, pancreas, intestine, and stomach. There are also other body parts used, such as the tissues, cell, and fluids like hand, cornea, skin, face, the islet of Langerhans, bone marrow or adult stem cell, blood transfusion or body parts transfusion, blood vessels, heart valve, and the bones.

Types of Donors

The organ transplantation that comes from a deceased donor will only be the heart, pancreas, stomach, hand, cornea, and blood vessels while the other organs mentioned above can be from both deceased or living donors. Deceased donors, formerly known as cadaveric donors, are those who have been declared brain dead but the organs are still useful. These organs are kept viable through ventilators or other mechanical mechanism until transplantation to a recipient is performed. Living donors are those alive who donate a replaceable tissue, cell, or fluid, or donates an organ or part of the organ that can still allow the donor to function despite the absence of the donated organ or part of an organ.

So what is the connection of organ transplant to shingles? The connection is actually pretty simple. In this medical procedure, organ rejection from the recipient is the anticipated problem and can be critical. When an organ is being transplanted to another species or to the organ recipient, the organ will be considered as a foreign body which can result to an organ transplant rejection or a failure of organ transplantation. For such reasons, medications are prescribed or administered to the recipient before the procedure so that the recipient’s body will not reject the transplant.

The medication administration continues until there are no signs and symptoms of organ transplant rejection that are observable. Immunosuppresant drugs are used for the organ recipient in order to prevent transplant rejection. However, such drugs can suppress his or her immune system. Once the recipient’s immune system is suppressed, it leads to a weak immune system, which, in turn, means any sort of infection that is caused by bacteria or a virus can penetrate the recipient’s body. Therefore, a weak immune system is indeed prone to acquire herpes zoster or shingles.
