Infectious Causes of Vulvovaginal Pruritus
Vulvovaginal pruritus, or itching, is most commonly caused by infections. The leading infectious agents include Candida species (causing vulvovaginal candidiasis), bacterial vaginosis, and Trichomonas vaginalis. Candidiasis is especially prevalent, affecting up to 75% of women at least once in their lives, and is characterized by intense itching, abnormal discharge, and sometimes pain or redness. Risk factors for candidiasis include pregnancy, diabetes, use of antibiotics or steroids, hormonal changes, and certain hygiene habits. Bacterial vaginosis and trichomoniasis are also significant contributors, particularly in sexually active women. Imbalances in the vaginal microbiota can lead to overgrowth of these organisms, resulting in pruritus and other symptoms. In children, pinworm (Enterobius vermicularis) infection can also cause vulvovaginal itching, especially with nocturnal symptoms2345+4 MORE.
Non-Infectious and Inflammatory Causes
Non-infectious causes are also important and include inflammatory skin conditions such as lichen sclerosus, atopic dermatitis, contact dermatitis, and psoriasis. Lichen sclerosus is a common cause, not only in postmenopausal women but also in young girls before puberty. These conditions can cause chronic itching, redness, and skin changes, and may require different management strategies than infections1210.
Neuropathic and Systemic Factors
Neuropathic disorders and systemic illnesses can also contribute to vulvovaginal pruritus. These may include nerve-related conditions or underlying systemic diseases that affect skin health or immune function. Such cases often require a multidisciplinary approach for accurate diagnosis and effective treatment110.
Hormonal, Environmental, and Hygiene-Related Factors
Hormonal changes, such as those occurring during pregnancy or menopause, can alter the vaginal environment and increase susceptibility to pruritus. Personal hygiene practices, including the use of scented products or harsh soaps, and environmental exposures can also irritate the vulvar area and trigger itching. Maintaining a healthy vaginal microbiota is crucial, as disruptions can lead to both infectious and non-infectious causes of pruritus15710.
Mixed and Chronic Cases
In many cases, vulvovaginal pruritus results from a combination of factors, including infections, inflammatory conditions, and environmental triggers. Chronic or recurrent cases may require comprehensive evaluation to identify all contributing causes. Psychological factors and the impact on quality of life should also be considered in long-term management110.
Conclusion
Vulvovaginal pruritus has a wide range of causes, including infections (such as candidiasis, bacterial vaginosis, trichomoniasis, and pinworm), inflammatory skin diseases (like lichen sclerosus and dermatitis), neuropathic and systemic conditions, hormonal changes, and environmental or hygiene-related factors. Accurate diagnosis often requires considering multiple potential causes, and effective management depends on addressing the underlying factors and the overall impact on the patient’s well-being1234+5 MORE.
