Abstract

Topical steroids, commonly used for a wide range of skin disorders, are associated with side effects both systemic and cutaneous. This article aims at bringing awareness among practitioners, about the cutaneous side effects of easily available, over the counter, topical steroids. This makes it important for us as dermatologists to weigh the usefulness of topical steroids versus their side effects, and to make an informed decision regarding their use in each individual based on other factors such as age, site involved and type of skin disorder.

 Introduction



Topical steroids were introduced in 1951, when Sulzberger and Witten first used topical hydrocortisone. [1] The anti-inflammatory and anti-proliferative actions of topical steroids result not only in their therapeutic effect but also in their side effects [Table 1]. In this way steroids act as a double-edged sword, which makes it important to use it with the utmost caution.{Table 1}

 Adverse Effects of Topical Steroids on Skin



Steroid Atrophy [Figure 1]

Physiology of skin atrophy due to topical steroids

Topical steroids cause the synthesis of lipocortin, which inhibits the enzyme phospholipase A2. Phospholipase A2 acts on the cell membrane phospholipids, to release arachidonic acid which causes the inflammation. The inhibition of phospholipase A2 results in the reduction of inflammation, mitotic activity and protein synthesis. [2]{Figure 1}

Topical steroid use causes skin to go through three phases-preatrophy, atrophy and finally tachyphylaxis. Atrophy causes a burning sensation, and further steroid use causes vasoconstriction and soothing of the burning. When topical steroids are withdrawn, vasodilation occurs, till the vessels become more dilated than their initial diameter, and this is known as a "trampoline-like effect". This occurs due to the effect of steroids on nitric oxide in the endothelium. Release of endothelial nitric oxide stores results in "hyperdilation" of vessels. [3]

Pathogenesis of skin atrophy due to topical steroids

Inhibitory effect on keratinocyte proliferation in the epidermisInhibition of collagen 1 and 3 synthesis in the dermisInhibition of fibroblasts and hyaluronan synthase 3 enzyme resulting in the reduction of hyaluronic acid in the extracellular matrix leading to dermal atrophy. [1],[4]

Factors that increase chances of atrophy are: Extremities of age, body site e.g. intertriginous areas, high-potency topical steroid, occlusion and moisture.

 Steroid-Induced Telangiectasia



Steroid-induced telangiectasia occurs due to stimulation of release of nitric oxide from dermal vessel endothelial cells leading to abnormal dilatation of capillaries. [1]

 Steroid Acne



The pathogenesis of topical steroid-induced acne has been proposed to be due to the degradation of the follicular epithelium, resulting in the extrusion of the follicular content. [1]

Factors predisposing to steroid acne are high concentration of the drug, application under occlusion, young adults below age 30, whites in preference to blacks and application to acne-prone areas of face and upper back.

 Steroid Rosacea



Topical steroids increase the proliferation of Propionibacterium acnes, and Demodex folliculorum, leading to an acne rosacea-like condition within 6 months. It is also known as "iatrosacea", "topical steroid-induced rosacea-like dermatitis" (TCIRD) or "topical steroid-dependent face" (TSDF) [Figure 2]. [5] Mometasone furoate, known to be safe for use on the face, in reality is a medium-potency steroid, and has resulted in "mometasone-induced steroid rosacea". [6] Steroid-induced rosacea has been commonly associated with topical fluorinated steroids. [5]{Figure 2}

 Perioral Dermatitis



Facial perioral dermatitis, more commonly seen in females, presents with follicular papules and pustules on an erythematous background, with sparing of the skin near the vermillion border of the lips. Steroid-induced perioral dermatitis is differentiated from common perioral dermatitis by history and clinical examination. Steroid-induced dermatitis has more erythema, inflammation, and scaling than its counterparts. Patients with steroid-induced dermatitis present with squeezed tubes of steroids that they have used and abused in hope of resolution of the skin condition. Hence, the term "tortured tube" sign. Substitution of hydrocortisone for fluorinated steroids resulted in the improvement of steroid-induced perioral dermatitis. [1],[7],[8]

 Purpura, Stellate Pseudoscars, Ulcerations



Steroid-induced protein degradation leads to dermal atrophy and loss of intercellular substance, which further cause blood vessels to lose their surrounding dermal matrix, resulting in the fragility of dermal vessels, purpuric hypopigmented, and depressed scars. [1]

 Aggravation of Cutaneous Infections



Tinea versicolor, onychomycosis, dermatophytosis and Tinea incognito [Figure 3] are the common cutaneous infections aggravated by topical steroids. Granuloma gluteale infantum is a persistent reddish purple, granulomatous, papulonodular eruption on the buttocks and thighs of infants. It occurs when diaper dermatitis is treated with topical steroids. [1]{Figure 3}

 Delayed Wound Healing



Delayed wound healing may occur due to various reasons. Inhibition of keratinocytes may cause epidermal atrophy and delayed re-epithelialization. Inhibition of fibroblasts-reduced collagen and ground substance may result in dermal atrophy and striae. Inhibition of vascular connective tissue may cause telangiectasia and purpura. Delayed granulation tissue formation may be caused by inhibition of angiogenesis. [1]

 Contact Sensitization to Topical Steroids



Contact sensitization may occur due to prolonged use of steroids and application of certain drugs (e.g. nonfluorinated steroids - hydrocortisone, hydrocortisone 17-butyrate, budesonide). It is associated with cream formulations of steroids more often than ointments. Contact sensitization to topical steroids occurs due to the binding to amino acid arginine as part of certain proteins. Contact sensitization to steroids must be differentiated from hypersensitivity to other constituents e.g. lanolin, parabenes, antibiotics. [1]

Allergic contact dermatitis to topical steroids, presents as absence of response to treatment or as worsening of the dermatitis. It is usually seen in children with atopic dermatitis. Also, mild potent, steroids used commonly in children like desonide and hydrocortisone butyrate have an allergic property due to their structural instability. Some commonly used potent steroids are rare allergens, e.g. fluorinated corticosteroids, clobetasol propionate, betamethasone dipropionate, mometasone, etc. [9]

 Eyelid Dermatitis



Patients with atopic and seborrheic dermatitis on chronic topical steroids, develop a flare around the eyes within 5-7 days after stoppage of steroids.

 Tachyphylaxis



Topical corticosteroids may induce tachyphylaxis with chronic use. This is why the frequency of application of ultrahigh-potency topical corticosteroids is reduced after the first 2 weeks to no more than four or five times a week. Initially, steroids are effective; however, as time passes, patients stop responding to the same topical steroid and require oral steroids. Patients usually complain that steroids "are not effective anymore". [1]

 Trichostasis Spinulosa



A study has shown the association of trichostasis spinulosa with topical steroids. It is characterized by dark-brown, follicular papules involving the face, neck, upper chest, arms, and antecubital areas with a rough sensation on palpation. On examination, tufts of hairs are visible projecting through each of the tiny papules. Treatment involves daily tretinoin 0.05% cream. [10]

 Striae (Rubrae Distensae)



Striae due to steroids must be differentiated from those due to weight gain and pregnancy.

Pathogenesis of striae, according to Shuster, is due to the cross linking of immature collagen in the dermis, resulting in intradermal tears causing striae [Figure 4]. [11] Studies also show that deposition of collagen and scar tissue formation are implicated in the formation of striae. [1]{Figure 4}

 Post Peel (Laser) Erythema Syndrome



Persistent redness of the face, after peel or laser has been noted in patients using topical steroids before the procedure. [3]

 Status Cosmeticus



Women with status cosmeticus cannot tolerate makeup and complain of a continuous burning sensation after any application. Patients present with erythema and burning disproportionate to the redness. Examination reveals atrophy, telangiectasia, and acneiform papules. With steroid withdrawal, the atrophy eventually clears. [3]

 Chronic Actinic Dermatitis-Like Eruption



Patients present with facial erythema and lichenification on the face, forearms and upper neck. The difference between this condition and photo exacerbated dermatitis is that even though the rash is on the photo distributed area, it does not flare on sun exposure. [3]

 Corticosteroid Withdrawal Patterns



The pattern of corticosteroid withdrawal is as follows: A week after corticosteroids are stopped, a mild erythema occurs at the site of the original dermatitis. This flare lasts for 2 weeks ending with desquamation. Dermatitis localized to the eyelids, face, scrotum, or perianal area often persists. A second flare usually occurs within 2 weeks. This pattern of flare and resolution repeats itself but each time smaller duration of flares and longer resolution periods. The length of the time for which steroids had been used initially determines the duration of the withdrawal phase. [3]

 Conclusion



The key to safe use of topical steroid is short term use of appropriate potency steroid. However, when the skin condition remains resistant to treatment or affects a particular sensitive area, the prolonged use of steroids is not advisable. Selective glucocorticoid receptor agonists are being developed that have independent transrepression and transactivation action. This may lead to the development of a topical steroid without its adverse effects. [12]
