Introduction
The varicella-zoster virus, which is also responsible for chickenpox, causes shingles, also known as herpes zoster, a painful skin rash condition. After an individual recovers from chickenpox, typically during childhood, the varicella-zoster virus remains dormant in certain nerve cells within the body. This virus remains inactive in most adults and does not result in shingles. However, approximately one in three adults may experience a reactivation of the virus, leading to the development of shingles. Shingles are not a contagious condition in the conventional sense, as one cannot directly contract shingles from another person who has the condition. However, there is a small possibility that an individual with an active shingles rash can transmit the varicella-zoster virus to someone who has never had chickenpox or has not been vaccinated against it.
How Serious Is Shingles in the Elderly?
Shingles in the elderly can sometimes lead to serious complications, particularly if their immune system is weakened or suppressed due to their age. While shingles itself is rarely life-threatening, it can give rise to complications. Complications occur more frequently in elderly individuals, and approximately 1 in every 1,000 cases of shingles in adults over the age of 70 can be fatal. These complications can encompass:
1. Postherpetic neuralgia (chronic pain condition that can develop after a shingles infection).
2. Eye problems.
3. Ramsay Hunt syndrome (a condition resulting from varicella-zoster virus infection that leads to facial nerve inflammation, often accompanied by painful shingles, facial paralysis, and hearing loss).
4. Infection of the shingles rash by bacteria.
5. Development of white patches (loss of pigment) or scarring in the affected rash area.6. Inflammation of vital organs, such as:
- Lungs (pneumonia, inflammation, and infection of the lungs).
- Liver (hepatitis, an inflammatory condition affecting the liver).
- Brain (encephalitis, inflammation of the brain).
- Spinal cord (transverse myelitis, inflammation of the spinal cord).
- The membranes that surround the brain and spinal cord (meningitis, inflammation of the membranes surrounding the brain and spinal cord).
- These organ-related complications are rare but can be severe.
Notably, shingles not only occur more frequently in the elderly but also lead to a higher rate of hospitalizations and fatalities in this age group. While shingles itself is not a common cause of death, the complications it can bring about tend to be more severe in seniors and individuals with compromised immune systems.
How Common Is Shingles in Seniors?
Shingles is most commonly observed in individuals over the age of 50. According to researchers, around half of all shingles cases are diagnosed in individuals aged 60 and above, and the likelihood of developing shingles substantially increases once an individual reaches the age of 70. According to research, almost 50 % of people who survive to be 85 years old will get shingles at some point in their lives. It has been estimated that approximately one in three people will develop shingles at some point in their lives, and the risk of complications escalates significantly after the age of 60.
What Triggers Shingles in Older Adults?
Shingles in older adults can be triggered by various factors, primarily due to the weakening of their immune systems, which makes it more challenging to combat infections. The age-related decline in the strength of the immune system is one significant contributing factor.
Furthermore, several other factors can further compromise the immune system of older individuals, including stressful life events and undergoing cancer treatment. These additional stressors can make an older person's immune system more vulnerable. While most individuals who develop shingles recover and typically do not experience recurrent episodes, it is worth noting that shingles can occur more than once in some cases.
What Are the Symptoms of Shingles in Older People?
The symptoms of shingles in older adults are characterized by a range of discomforts and skin manifestations. When it reactivates, it leads to the development of shingles. The typical symptoms of shingles in older adults include:
-
A tingling or burning sensation on the skin in a particular area of the body.
-
An itchy rash.
-
Fluid-filled blisters.
-
Skin sensitivity to touch.
-
Presence of fever, nausea, and headaches.
A shingles rash typically appears in the form of a band on one side of the body, commonly on the chest, abdomen, or face, which serves as a helpful diagnostic indicator. Pain may be experienced a few days before the appearance of blisters or skin irritation and can persist even after the rash has subsided.
Significantly, compared to younger people, older adults typically experience more severe versions of these symptoms, especially the rash and pain. If not promptly treated, the pain can become chronic in older adults.
In addition to the symptoms mentioned, other shingles symptoms may include:
-
Headache.
-
Sensitivity to light.
-
Flu-like symptoms (without fever).
-
Itching.
-
Pain in specific areas of the body.
-
A rash characterized by blisters that fill with fluid and crust over.
-
Healing of the rash may take several weeks and can result in scarring. It is important to note that not all individuals will experience all the symptoms of shingles, with some having milder symptoms while others may experience more severe ones.
What Are the Treatment Options of Shingles in Older People?
The treatment options for shingles in older people involve a combination of antiviral and pain medications, as well as various strategies to alleviate symptoms and support recovery:
-
Antiviral Medication: The primary approach to combating a shingles outbreak is antiviral medication. Three types of antiviral drugs - Acyclovir, Valacyclovir, and Famciclovir - are approved for older adults. Valacyclovir, due to its ease of use with three daily doses, is often the preferred choice for older shingles patients. These antiviral medications help clear up the blisters more rapidly and reduce severe pain.
-
Pain Medication: For mild pain, Acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs) like Ibuprofen or Naproxen can provide relief. More severe pain may necessitate the use of opioid pain relievers or corticosteroids. However, the use of these medications and their potential interactions with other drugs should be closely monitored in older adults.
-
Anticonvulsant Medications: In cases where other treatments are ineffective, anticonvulsant drugs such as Gabapentin and Pregabalin may be prescribed. It is important to monitor their use in older individuals, as these drugs can cause dizziness. Taking them before bedtime may reduce the risk of dizziness-related falls.
-
Mindful Meditation: Research suggests that the practice of mindful meditation may help manage pain and improve functioning in individuals with shingles. Meditation training and daily practice could complement traditional pain management therapies.
How Long Does It Take To Recover From Shingles?
Shingles typically last two to six weeks. Starting antiviral medication promptly accelerates the healing process of the rash and alleviates symptoms. If the rash becomes infected, recovery may take longer. In some cases, shingles can lead to postherpetic neuralgia (PHN), which is a chronic pain condition that can develop after a shingles infection, continuing long after the rash has healed. This persistent pain lasts from weeks to years.
How Can Shingles Be Prevented in Older Adults?
The best way to prevent shingles is to get a vaccine called Shingrix, which is recommended for individuals over the age of 50. Even if someone has had shingles before, they are still advised to get the vaccine as a preventative measure.
Conclusion
In conclusion, shingles in the elderly can cause serious outcomes if ignored, which include death. Therefore, it is of utmost importance to seek medical attention promptly when shingles symptoms are suspected, as early treatment can reduce the severity of the condition and the risk of complications. Additionally, various self-care measures can help alleviate symptoms and support recovery.
