Introduction

Seborrheic dermatitis is not directly causally related to HIV/AIDS, but AIDS can increase the risk and severity of seborrheic dermatitis. Most cases of seborrheic dermatitis are triggered by intrinsic factors; only some HIV/AIDS patients develop this skin condition secondarily due to immune deficiency. It is important to maintain skin cleanliness, use mild cleansing and skincare products, and avoid scratching or other irritants in daily life.

Seborrheic dermatitis has no direct causal relationship with HIV/AIDS; however, HIV infection can increase both the risk and severity of seborrheic dermatitis. Most cases of seborrheic dermatitis are triggered by intrinsic factors, and only some individuals with AIDS develop this skin condition secondary to immune deficiency. A detailed analysis is as follows:

Seborrheic dermatitis is a common chronic skin disorder primarily associated with Malassezia fungal infection and abnormal sebum production. Other contributing factors include genetics, mental stress, and deficiency of B-complex vitamins. Patients typically develop red, greasy, scaly patches accompanied by itching in areas rich in sebaceous glands. Symptoms can usually be relieved with antifungal skincare products. The majority of affected individuals have normal immune function, indicating that the condition is not inherently linked to AIDS, and therefore should not cause undue concern.

In people living with HIV/AIDS, the destruction of CD4+ T lymphocytes by the virus leads to severe immune impairment and weakened skin barrier defenses, allowing Malassezia fungi to overgrow and trigger inflammatory reactions. As a result, seborrheic dermatitis occurs more frequently and tends to be more persistent in these patients. However, it is not a specific or diagnostic sign of AIDS, and HIV infection cannot be diagnosed based solely on skin manifestations.

In daily life, maintaining skin cleanliness with gentle skincare products and avoiding scratching or irritation is essential. For scalp involvement, shampoos containing ketoconazole are recommended. Additionally, dietary supplementation with B-complex vitamins, regular sleep patterns, and stress reduction can help manage symptoms.
