Pruritus Vulva

Pruritus vulvae, commonly known as vulvar itching, is a distressing symptom affecting the external female genitalia (vulva). It can significantly impact a woman’s quality of life, leading to discomfort, sleep disturbances, and emotional distress. While it can occur at any age, it is more prevalent in postmenopausal women.

Causes: 

The causes of pruritus vulvae are diverse and can be broadly categorized into:

• Infectious: Vulvovaginal candidiasis (most common), bacterial vaginosis, sexually transmitted infections, etc.
• Inflammatory/Dermatologic: Irritant or allergic contact dermatitis, lichen sclerosus, eczema, psoriasis, etc.
• Neoplastic: Vulvar intraepithelial neoplasia (VIN), vulvar cancer.
• Other: Atrophic vaginitis, diabetes mellitus, neurogenic pruritus, psychogenic pruritus, etc.

Clinical Features:

• Itching: The primary symptom, varying in intensity and duration
• Skin changes: Redness, swelling, excoriations, fissures, lichenification, dryness, etc.
• Associated symptoms: Burning, stinging, dyspareunia, vaginal discharge, urinary symptoms

Diagnosis:

• Detailed history and physical examination
• Laboratory tests: Wet mount, cultures, blood tests, allergy testing
• Additional tests: Biopsy, colposcopy, patch testing

Treatment:

• Addressing the underlying cause (e.g., antifungal for candidiasis, corticosteroids for dermatitis)
• Symptomatic relief: Cool compresses, antihistamines, topical anesthetics
• Lifestyle modifications: Avoiding irritants, wearing cotton underwear, practicing good hygiene
• Psychological support if needed

Prevention:

• Avoiding douching and harsh soaps
• Wearing breathable clothing
• Managing underlying medical conditions
• Practicing good hygiene[7]

Unfortunately, I could not find any specific epidemiological studies on Pruritus Vulva conducted exclusively in India with the year of publication. However, I can share some relevant information that may be helpful:

• A study titled "Pruritus Vulvae: A Clinicomycological Study" published in the Indian Journal of Dermatology, Venereology and Leprology in 2007, investigated the causes of pruritus vulvae in 100 women attending a dermatology outpatient department. The study found that the most common causes were fungal infections (58%), followed by irritant or allergic contact dermatitis (22%) and bacterial infections (10%).[4]

• Another study, "Clinical and Etiological Profile of Pruritus Vulvae" published in the Indian Journal of Sexually Transmitted Diseases and AIDS in 2015, examined 100 women with pruritus vulvae. This study reported similar findings, with fungal infections being the most common cause (52%), followed by bacterial vaginosis (20%) and irritant or allergic contact dermatitis (14%).[5]

While these studies do not provide specific epidemiological data such as prevalence or incidence rates, they offer valuable insights into the common causes of pruritus vulvae in Indian women.

It is important to note that further research is needed to establish the true epidemiological picture of pruritus vulvae in India.

Pruritus Vulva can broadly be categorized into several types based on underlying causes:

1. Infectious:

• Fungal infections: Candidal vulvovaginitis is the most common cause
• Bacterial infections: Bacterial vaginosis, though less frequent, can also contribute
• Viral infections: Herpes simplex virus can cause recurrent outbreaks with associated pruritus
• Parasitic infestations: Scabies or pubic lice can infrequently cause vulvar itch

2. Inflammatory/ Dermatological:

• Irritant or allergic contact dermatitis: Reaction to soaps, detergents, feminine hygiene products, etc.
• Lichen sclerosus: Chronic inflammatory condition causing thinning and whitening of vulvar skin
• Eczema/ Atopic dermatitis: Chronic skin condition with red, itchy patches
• Psoriasis: Autoimmune condition causing thick, scaly patches on skin

3. Neoplastic:

• Vulvar Intraepithelial Neoplasia (VIN): Precancerous changes in vulvar skin can sometimes present with itch
• Vulvar cancer: Though rare, can cause persistent pruritus

4. Other:

• Hormonal changes: Atrophic vaginitis due to estrogen deficiency in menopause
• Neurogenic pruritus: Itch originating from nerve dysfunction
• Psychogenic pruritus: Itch linked to psychological factors
• Idiopathic pruritus: Itch with no identifiable cause

Note: This categorization is based on the information presented in the reference book. Other classifications or subtypes might exist in different literature or clinical practices.[6]

1. Personal Hygiene and Lifestyle:

• Frequent douching: Disrupts the natural vaginal flora, increasing the risk of infections
• Use of harsh soaps, detergents, or feminine hygiene products: Can cause irritation and allergic reactions
• Wearing tight-fitting or synthetic clothing: Creates a warm, moist environment favorable for fungal and bacterial growth
• Excessive sweating: Can contribute to irritation and maceration of the vulvar skin

2. Medical Conditions:

• Diabetes mellitus: High blood sugar levels can promote fungal growth and impair the immune system
• Immunosuppression: Weakened immune system increases susceptibility to infections
• Urinary or fecal incontinence: Chronic moisture and irritation can predispose to skin breakdown and infections
• Sexually transmitted infections (STIs): Can cause vulvar lesions and inflammation

3. Hormonal Factors:

• Menopause: Estrogen deficiency leads to atrophic changes in the vulvar skin, making it more prone to irritation and infections
• Pregnancy: Hormonal fluctuations and increased vaginal discharge can increase the risk of vulvovaginal candidiasis

4. Other Factors:

• History of atopic dermatitis or other allergic conditions: Increases the likelihood of developing allergic contact dermatitis
• Psychological stress: Can exacerbate existing pruritus or trigger psychogenic pruritus
• Certain medications: Some medications can cause dryness or allergic reactions in the vulvar area

Note: This list of risk factors is not exhaustive. Other factors might also contribute to the development of Pruritus Vulva.[8]

The pathogenesis of Pruritus Vulva is complex and multifactorial, often involving an interplay of various factors:

1. Inflammation:

• Infectious agents: Bacteria, fungi, viruses, or parasites can trigger an inflammatory response in the vulvar skin, leading to the release of inflammatory mediators (histamine, prostaglandins, cytokines) that stimulate itch receptors.
• Irritant or allergic contact dermatitis: Exposure to irritants or allergens can initiate an inflammatory cascade, causing pruritus.
• Chronic inflammatory conditions: Lichen sclerosus and other dermatological conditions can result in chronic inflammation and persistent itch.

2. Nerve Sensitization:

• Peripheral nerve sensitization: Chronic inflammation or nerve injury can lead to heightened sensitivity of peripheral nerves, resulting in increased itch perception.
• Central sensitization: Persistent pruritus can lead to changes in the central nervous system, amplifying the itch sensation and making it more difficult to control.

3. Dryness and Atrophy:

• Menopausal changes: Estrogen deficiency can lead to vulvar atrophy, causing dryness, thinning of the skin, and increased susceptibility to irritation and pruritus.
• Other causes of dryness: Certain medications, soaps, and environmental factors can contribute to dryness and exacerbate itch.

4. Psychological Factors:

• Psychogenic pruritus: Psychological stress, anxiety, or depression can trigger or worsen pruritus in some individuals.
• Itch-scratch cycle: The act of scratching can provide temporary relief but can also further damage the skin, leading to more inflammation and pruritus, perpetuating the cycle.

5. Other Factors:

• Neoplastic processes: Vulvar intraepithelial neoplasia (VIN) or vulvar cancer can sometimes present with pruritus as an early symptom.
• Hormonal fluctuations: Changes in hormone levels during pregnancy or menstruation can sometimes contribute to pruritus.
• Idiopathic pruritus: In some cases, no specific underlying cause can be identified.

Note: This overview of pathogenesis is based on the information presented in the reference book. Further research is ongoing to fully elucidate the complex mechanisms involved in Pruritus Vulva.[7]

The pathophysiology of Pruritus Vulva involves a complex interplay of various factors, leading to the sensation of itch:

1. Sensory Nerve Stimulation:

• Itch Receptors: The vulvar skin is richly innervated with sensory nerve fibers containing specialized itch receptors (pruriceptors). These receptors can be activated by various stimuli, including inflammatory mediators, histamine, neuropeptides, and other pruritogens.
• Neurogenic Inflammation: In some cases, the itch sensation itself can trigger the release of additional inflammatory mediators from nerve endings, further amplifying the itch response.

2. Inflammatory Mediators:

• Histamine: Released from mast cells and basophils in response to allergens, irritants, or infections, histamine is a potent pruritogen that directly activates itch receptors.
• Prostaglandins and Leukotrienes: These inflammatory mediators, produced by various cells in response to tissue injury or inflammation, can sensitize nerve endings and contribute to itch.
• Cytokines: Released by immune cells during inflammation, cytokines can modulate the itch response and contribute to chronic pruritus.

3. Skin Barrier Disruption:

• Dryness and Atrophy: Estrogen deficiency in menopause or other conditions can lead to vulvar atrophy, causing dryness, thinning of the skin, and increased susceptibility to irritation and pruritus.
• Irritants and Allergens: Exposure to harsh soaps, detergents, feminine hygiene products, or other irritants can disrupt the skin barrier, allowing penetration of pruritogens and triggering inflammation.

4. Central Sensitization:

• Chronic Itch: Persistent pruritus can lead to changes in the central nervous system, resulting in increased sensitivity to itch stimuli and a lower threshold for itch perception.
• Psychogenic Factors: Stress, anxiety, and depression can modulate the central processing of itch and contribute to chronic pruritus.

5. Other Factors:

• Infections: Vulvovaginal candidiasis, bacterial vaginosis, and other infections can trigger inflammation and pruritus.
• Hormonal Fluctuations: Changes in hormone levels during pregnancy or menstruation can sometimes contribute to pruritus.
• Neoplastic Processes: Vulvar intraepithelial neoplasia (VIN) or vulvar cancer can sometimes present with pruritus.

Note: The pathophysiology of Pruritus Vulva is complex and not fully understood. Further research is ongoing to elucidate the precise mechanisms involved.[9]

1. Itching:

• The hallmark symptom, often described as intense, burning, or stinging
• Can be localized to the vulva or extend to the perineum, anus, or inner thighs
• May be intermittent or continuous, and can worsen at night or with certain triggers (heat, moisture, friction)

2. Skin Changes:

• Redness, swelling, and inflammation of the vulvar skin
• Excoriations, fissures, or lichenification (thickening of the skin with accentuated skin markings) due to scratching
• Dryness, scaling, or cracking of the skin, particularly in atrophic vulvitis
• White patches or plaques in lichen sclerosus
• Vesicles or ulcers in herpes simplex virus infection

3. Associated Symptoms:

• Burning or stinging sensation
• Pain or discomfort during sexual intercourse (dyspareunia)
• Vaginal discharge (abnormal color, odor, or consistency)
• Urinary symptoms (frequency, urgency, dysuria) in cases of concomitant urinary tract infection

4. Psychological Impact:

• Frustration, anxiety, and embarrassment due to persistent itch
• Sleep disturbances due to nighttime itching
• Reduced quality of life and sexual dysfunction

Note: The specific clinical features can vary depending on the underlying cause of Pruritus Vulva. A thorough history and physical examination are essential for accurate diagnosis and management.[10]

The clinical examination for Pruritus Vulva should be comprehensive and include the following components:

1. Inspection:

• Careful visual examination of the entire vulvar region, including the mons pubis, labia majora and minora, clitoris, vestibule, and perineum.
• Note any skin changes such as redness, swelling, excoriations, fissures, lichenification, dryness, scaling, white patches, vesicles, or ulcers.
• Assess for signs of infection (discharge, odor, lesions) or atrophy (thinning of the skin, loss of rugal folds).

2. Palpation:

• Gently palpate the vulvar skin to assess for tenderness, induration, or masses.
• Examine the inguinal lymph nodes for enlargement or tenderness.

3. Speculum Examination:

• If indicated, perform a speculum examination to visualize the vaginal walls and cervix.
• Obtain samples for microbiological testing (wet mount, cultures) if infection is suspected.

4. Additional Assessments:

• Assess for signs of urinary or fecal incontinence, which can contribute to vulvar irritation.
• Evaluate for psychological distress or anxiety, which can exacerbate pruritus.

Note: A thorough clinical examination is essential for identifying the underlying cause of Pruritus Vulva and guiding appropriate management.[11]

Pruritus Vulva can have a wide range of differential diagnoses, including:

1. Infectious Causes:

• Vulvovaginal candidiasis (most common)

• Idiopathic pruritus

Note: The differential diagnosis of Pruritus Vulva can be extensive. A careful history, physical examination, and appropriate investigations are necessary to arrive at the correct diagnosis and guide management.[12]

Pruritus Vulva is often a benign and self-limiting condition, it can lead to several complications if left untreated or inadequately managed:

1. Skin Changes:

• Lichenification: Chronic scratching can lead to thickening and leathery changes in the vulvar skin, making it more prone to irritation and infection.
• Excoriations and Fissures: Persistent scratching can cause breaks in the skin, increasing the risk of secondary bacterial or fungal infections.
• Hyperpigmentation: Chronic inflammation can lead to darkening of the vulvar skin.

2. Infections:

• Secondary bacterial or fungal infections: Breaks in the skin from scratching can provide an entry point for pathogens, leading to cellulitis, abscesses, or impetigo.
• Recurrent vulvovaginal infections: Chronic inflammation and disruption of the normal vaginal flora can predispose to recurrent infections, such as candidiasis or bacterial vaginosis.

3. Psychological Impact:

• Anxiety and Depression: Chronic pruritus can significantly impact a woman’s quality of life, leading to anxiety, depression, and social isolation.
• Sleep Disturbances: Nighttime itching can disrupt sleep patterns, leading to fatigue and impaired concentration.
• Sexual Dysfunction: Pain and discomfort during intercourse can lead to decreased sexual desire and avoidance of intimacy.

4. Rarely:

• Vulvar Cancer: In rare cases, persistent pruritus can be a presenting symptom of vulvar cancer, particularly in older women.

Note: Early diagnosis and effective management of Pruritus Vulva are crucial to prevent these potential complications.[13]

The investigation of Pruritus Vulva aims to identify the underlying cause and guide appropriate management. It typically involves the following:

1. Detailed History:

• Onset, duration, and characteristics of the itch (location, severity, timing, triggers)
• Associated symptoms (vaginal discharge, urinary symptoms, skin changes)
• Medical history (diabetes, allergies, STIs, medications)
• Sexual history
• Personal hygiene practices

2. Physical Examination:

• Careful inspection of the vulva, perineum, and perianal area
• Assessment for skin changes, discharge, lesions, or signs of infection
• Speculum examination if indicated

3. Laboratory Investigations:

• Wet mount preparation of vaginal discharge to identify Candida, Trichomonas, or bacterial vaginosis
• Vaginal pH measurement
• Cultures for bacteria, fungi, or viruses if indicated
• Blood glucose test if diabetes is suspected
• Allergy testing if allergic contact dermatitis is suspected

4. Additional Investigations (if indicated):

• Biopsy of vulvar skin lesions to rule out malignancy or other dermatological conditions
• Colposcopy to evaluate for cervical or vaginal pathology
• Patch testing to identify allergens
• Nerve conduction studies or imaging if neurogenic pruritus is suspected

Note: The specific investigations will depend on the clinical presentation and suspected etiology.[14]

Although not all cases of Pruritus Vulva are preventable, certain measures can help reduce the risk and recurrence:

1. Hygiene and Lifestyle:

• Avoid douching: It disrupts the natural vaginal flora, increasing susceptibility to infections.
• Use mild, unscented soaps and detergents: Harsh soaps can irritate the delicate vulvar skin.
• Wear cotton underwear and loose-fitting clothing: This allows for better air circulation and reduces moisture buildup.
• Change out of wet clothing promptly: Dampness can promote fungal and bacterial growth.
• Practice good toilet hygiene: Wipe from front to back after using the toilet to prevent contamination of the vulva with fecal bacteria.

2. Manage Underlying Medical Conditions:

• Control diabetes: Maintain good blood sugar control to reduce the risk of fungal infections.
• Treat infections promptly: Seek medical attention for any signs of vaginal or vulvar infection.
• Manage incontinence: Use appropriate products and techniques to minimize moisture and irritation.

3. Hormonal Management:

• Consider topical estrogen for atrophic vaginitis: This can help restore the vulvar skin’s health and reduce dryness.
• Discuss hormonal contraceptives with your doctor: Some contraceptives can alter the vaginal environment and increase the risk of infections.

4. Other Measures:

• Avoid irritants and allergens: Identify and avoid potential triggers, such as certain soaps, detergents, fabrics, or feminine hygiene products.
• Manage stress: Practice relaxation techniques or seek professional help to manage stress and anxiety.
• Avoid scratching: Scratching can further damage the skin and worsen the itch. Use cool compresses or topical medications to relieve itching.

Note: These preventive measures can help reduce the risk of Pruritus Vulva. However, if symptoms persist or recur, it is important to seek medical evaluation to identify and address the underlying cause.[15]

Although there is no specific "Pruritus Vulva Diet," certain dietary and lifestyle modifications can help manage symptoms and promote vulvar health:

Diet:

• Probiotics: Consuming foods rich in probiotics or taking probiotic supplements can help maintain a healthy balance of vaginal flora and reduce the risk of infections. Yogurt, kefir, sauerkraut, and kimchi are good sources of probiotics.
• Anti-inflammatory foods: Incorporate foods with anti-inflammatory properties into your diet. These include fruits, vegetables, whole grains, fatty fish, nuts, and seeds.
