Herpes Labialis

Overview of Herpes Labialis

• A few hours before the onset, there is a feeling of burning, or pain; this follow by a crop of vesicles which break down in 48 hours.
• These crops recur and the attack lasts for 3 to 7 days. It commonly occurs on the face at the mucocutaneous junction. [1]
• The rash usually heals within ten days, but the virus remains dormant in the trigeminal ganglion.[2]
• There may or may not a scar left after the attack. It precipitate by fever, strong sunlight, emotional stress, local trauma.[1]

Epidemiology of Herpes Labialis

In India, 63% of individuals were seropositive for Herpes Simplex Virus (HSV) in 2005. Within this figure, 33.3% were positive for HSV-1 and 16.6% were seropositive for HSV-2. Those with both HSV-1 and HSV-2 antibodies were estimated at 13.3% of the population. Indian men are more likely to be infected with HSV-2 than women, and increasing seroprevalence of this virus is associated with increasing age. [6]

Causes of Herpes Labialis (Cold sores)

• Cold sores are sometimes called oral herpes because they cause by the herpes simplex virus type 1 (HSV-1). This virus is very common and highly contagious.
• It spreads through saliva or close contact — often through kissing or by sharing utensils, straws, towels or lip balm with someone who has a cold sore.
• You may not know if you have infected with HSV-1 because symptoms of exposure to HSV-1 are generally mild.
• Children sometimes develop a fever and small blisters inside and around their mouths when they are first exposed to HSV-1.[4]

Exciting Factors:

• The infection is typically spread between people by direct non-sexual contact. Attacks can trigger by sunlight, fever, psychological stress, or a menstrual period.
• The infection is typically spread between people by direct non-sexual contact.
• Direct contact with the genitals can result in genital herpes. Diagnosis usually base on symptoms but can confirm with specific testing.[1]

Triggers factors:

• After you have been infected with HSV-1, the virus never goes away. It remains dormant (inactive) in a group of nerve cells in your face called the trigeminal ganglion.
• When the virus is triggered, or activated, it “wakes up” and travels through your nerves to your lips, where a cold sore develops. After an outbreak, the virus goes back to sleep in your body.
• What triggers a cold sore in one person might not cause an outbreak in another person. Some people with HSV-1 never develop a cold sore.
• A cold sore can be activated by a variety of factors, including:

• Hormonal changes during menstruation or pregnancy
• Sunburn
• Extreme temperatures (hot or cold)
• Stress (physical or emotional)
• Fatigue
• Fever and illness, such as cold or flu
• Damaged, dry or cracked lips[4]

Types

There are two types of Herpes Simplex Virus (HSV) that can cause Herpes Labialis (cold sores):

1. HSV-1: This is the most common cause of cold sores.
2. HSV-2: While primarily associated with genital herpes, HSV-2 can also cause cold sores in some cases. [7]

Risk factors

The primary risk factor for contracting Herpes Labialis (cold sores) is direct contact with someone who has an active lesion or with their saliva when they are shedding the virus (even if no sores are visible). Other risk factors include:

• Immunosuppression: Individuals with weakened immune systems are more susceptible to HSV infections and may experience more severe or frequent outbreaks.
• Stress: Emotional or physical stress can trigger outbreaks in individuals who are already infected with the virus.
• Sun exposure: Excessive sun exposure can also trigger outbreaks.

Pathogenesis of Herpes Labialis

The pathogenesis of Herpes Labialis (cold sores) involves several stages:

1. Primary Infection: The herpes simplex virus (usually HSV-1) enters the body through breaks in the skin or mucous membranes around the mouth. It then replicates in the epithelial cells, causing cell death and the formation of fluid-filled blisters.
2. Latency: After the initial infection, the virus travels along the nerve fibers to the trigeminal ganglion, where it establishes a latent (dormant) infection.
3. Reactivation: Various triggers (e.g., stress, sunlight, illness) can reactivate the virus, causing it to travel back down the nerve fibers to the skin, where it replicates and causes a new outbreak of cold sores. [9]

Pathophysiology

The pathophysiology of Herpes Labialis (cold sores) involves the following steps:

1. Primary Infection: The Herpes Simplex Virus (usually HSV-1) enters the body through breaks in the skin or mucous membranes around the mouth. The virus replicates in the epithelial cells, causing cell death and the formation of fluid-filled vesicles.

2. Viral Spread: The virus spreads to sensory nerve endings and travels along the axons to the trigeminal ganglion, where it establishes a latent infection.

3. Latency: During latency, the virus remains dormant within the neuronal cell bodies of the trigeminal ganglion.

4. Reactivation: Various triggers, such as stress, sunlight, fever, or hormonal changes, can reactivate the virus. The reactivated virus travels back down the nerve fibers to the skin, where it replicates and causes a new outbreak of cold sores.

5. Immune Response: The body’s immune system mounts an inflammatory response to the viral infection, leading to the characteristic signs and symptoms of cold sores, such as pain, redness, swelling, and blistering. [10]

Clinical Features

The clinical features of Herpes Labialis (cold sores) typically include:

1. Prodrome: Before the appearance of lesions, individuals may experience a prodrome of tingling, burning, itching, or pain in the area where the cold sore will develop.

2. Erythema and Edema: The affected area becomes red and swollen.

3. Vesicles: Small, painful, fluid-filled blisters appear, usually clustered together. These vesicles are typically located on the lips or around the mouth but can also occur on the nose, cheeks, or chin.

4. Ulceration: The vesicles rupture, leaving shallow, painful ulcers.

5. Crusting: The ulcers dry and form a crust, which eventually falls off as the lesion heals. [11]

Sign & Symptoms of Herpes Labialis

For many people, symptoms are more severe the first time they develop a cold sore. When you have a cold sore outbreak:

• The first sign of a cold sore is usually a tingling, burning, or itching sensation on or around the lips, beginning about 12-24 hours before the cold sore develops.
• The area becomes red, swollen and painful as the blisters form.
• Over 2-3 days, the blisters rupture and ooze fluid that is clear or slightly yellow. This is sometimes called the “weeping phase.”
• About 4-5 days after the cold sore appears, it crusts and scabs over. It might crack or bleed as it heals.
• The scab then falls off, revealing skin that may be a little more pink or reddish than usual for a few days. It usually takes 1-2 weeks for the cold sore to heal completely.[2]

Clinical Examination of Herpes Labialis

• Inspection: The clinician will visually examine the affected area, looking for the characteristic clustered vesicles, ulcers, or crusts on the lips or around the mouth. They will also assess the distribution, size, and number of lesions.

• Palpation: The clinician may gently palpate the lesions to assess for tenderness, induration, or fluctuation.

• Regional Lymph Nodes: The clinician may also palpate the regional lymph nodes (e.g., submandibular, preauricular) to check for enlargement or tenderness, which can indicate an active infection. [12]

Diagnosis of Herpes Labialis

• Generally, Your doctor can usually diagnose cold sores just by looking at them.
• To confirm the diagnosis, your doctor might take a sample from the blister for testing in a laboratory.[5]

Differential Diagnosis

• Aphthous stomatitis (canker sores): These ulcers typically occur inside the mouth, are not preceded by vesicles, and are not contagious.
• Herpangina: This viral infection causes painful sores in the back of the throat and is accompanied by fever and sore throat.
• Impetigo: This bacterial skin infection causes honey-colored crusts and is usually located on the face or extremities.
• Contact dermatitis: This allergic reaction causes itching, redness, and sometimes blisters, and it is usually triggered by contact with an irritant or allergen.
• Traumatic ulcers: These ulcers are caused by injury to the mouth and are not contagious. [13]

Complication of Herpes Labialis

• Eye infections
• Genital sores
• Eczema
• New born: Babies under 6 months old may develop complications such as high fever and seizures because their immune systems aren’t fully developed.
• Immunocompromised people: In detail, For people with weakened immune systems, the herpes simplex virus can lead to encephalitis (in other words, swelling of the brain). Besides this, If you have HIV or are undergoing chemotherapy, cold sores could more severe and could take longer to go away.[4]

Investigations 

The diagnosis of herpes labialis is often made clinically based on the characteristic appearance and location of the lesions. However, in some cases, laboratory investigations may be necessary to confirm the diagnosis or to differentiate it from other conditions. These investigations may include:

1. Viral Culture: This involves swabbing the lesion and sending the sample to a laboratory to isolate and identify the virus. It is most sensitive during the vesicular stage of the outbreak.

2. Polymerase Chain Reaction (PCR): This test detects viral DNA in the sample and is more sensitive than viral culture. It can also differentiate between HSV-1 and HSV-2.

3. Direct Fluorescent Antibody (DFA) Test: This test uses antibodies labeled with a fluorescent dye to detect viral antigens in the sample.

4. Tzanck Smear: This test involves scraping cells from the base of a lesion and examining them under a microscope for the characteristic multinucleated giant cells seen in herpes infections. [14] 

Treatment of Herpes Labialis

• Cold sores generally clear up without treatment in two to four weeks.
• Several types of prescription antiviral medications may speed the healing process. Examples include:
• Acyclovir (Zovirax)
• Valacyclovir (Valtrex)
• Famciclovir
• Penciclovir (Denavir)
• Despite no cure or vaccine for the virus, a human body’s immune system and specialty antigens typically fight the virus.
• Docosanol, a saturated fatty alcohol, is a safe also effective topical application that has been approved by the United States Food and Drug Administration for herpes labialis in adults with properly functioning immune systems.
• The duration of symptoms can be shortened a bit if an antiviral, anesthetic, zinc oxide or zinc sulfate cream is applied soon after it starts. [5]

Prevention of Herpes Labialis

• Avoid kissing, intimate contact and oral sex with someone who has a cold sore.
• Don’t share towels, razors, dishes, cutlery, straws, lip balm or lipstick.
• Wash your hands before touching your lips, eyes or genitals.

If you’ve already come into contact with HSV-1, do these to reduce risk of a cold sore outbreak:

• Try to stay healthy: A fever can trigger a cold sore, which is why people sometimes call them fever blisters.
• Get enough rest: Fatigue weakens your immune system and makes you more likely to get sick.
• Wear lip balm with SPF: Protecting your lips from sunburn can help you avoid an outbreak.

If you have a cold sore, be careful around babies. Always wash your hands, and do not kiss a baby until the cold sore has healed completely.[4]

Homeopathic Treatment of Herpes Labialis

What Homoeopathic doctors do?

A homeopathy doctor tries to treat more than just the presenting symptoms. The focus is usually on what caused the disease condition? Why ‘this patient’ is sick ‘this way’?.
