Background

Diaper dermatitis is caused by overhydration of the skin, maceration, prolonged contact with urine and feces, retained diaper soaps, and topical preparations and is a prototypical example of irritant contact dermatitis. Signs and symptoms are restricted in most individuals to the area covered by diapers.[1]

Pathophysiology

Diaper rash affects the areas within the confines of the diaper. Increased wetness in the diaper area makes the skin more susceptible to damage by physical, chemical, and enzymatic mechanisms. Wet skin increases the penetration of irritant substances. Superhydration urease enzyme found in the stratum corneum liberates ammonia from cutaneous bacteria. Urease has a mild irritant effect on nonintact skin. Lipases and proteases in feces mix with urine on nonintact skin and cause an alkaline surface pH, adding to the irritation. (Feces in breastfed infants have a lower pH, and breastfed infants are less susceptible to diaper dermatitis.) The bile salts in the stools enhance the activity of fecal enzymes, adding to the effect.

Candida albicans has been identified as another contributing factor to diaper dermatitis; infection often occurs after 48-72 hours of active eruption. It is isolated from the perineal area in as many as 92% of children with diaper dermatitis. Other microbial agents have been isolated less frequently, perhaps more as a result of secondary infections.

Epidemiology

Mortality/Morbidity

With the exception of an individual who is immunocompromised, no mortality is associated with diaper rash when correctly diagnosed. However, a rash incorrectly diagnosed as diaper dermatitis certainly may lead to significant morbidity and mortality if associated with a serious illness.

Morbidity associated with diaper dermatitis is discomfort and the possibility of secondary bacterial or candidal infection, which may be more severe in an individual who is immunocompromised.

Race

No racial difference is observed.

Sex

No sexual difference is noted.

Age

Diaper dermatitis commonly affects infants, with peak incidence occurring when the individual is aged 9-12 months. One study determined that at any given time, diaper dermatitis is prevalent in 7-35% of the infant population.[2]

Diaper dermatitis can affect persons of any age who wear diapers, in particular, elderly people.
