Which bacterium is most directly involved in acne pathogenesis?
Pseudomonas aeruginosa
Staphylococcus aureus
Propionibacterium acnes
Streptococcus pyogenes
Propionibacterium acnes is an anaerobic bacterium that colonizes hair follicles and contributes to inflammation in acne lesions. It plays a key role in acne pathogenesis through lipase activity and inflammatory mediators.
What does a closed comedo typically present as?
Cyst
Blackhead
Papule
Whitehead
A closed comedo, commonly called a whitehead, is covered by a thin layer of skin and appears as a small, flesh-colored bump. It results from follicular plugging without oxidation of sebum.
Which topical agent has keratolytic properties and helps to unclog pores?
Salicylic acid
Dapsone
Isotretinoin
Clindamycin
Salicylic acid is a beta-hydroxy acid that penetrates lipid-rich follicles and promotes exfoliation by dissolving intercellular desmosomes. Its keratolytic action helps to clear comedones and prevent new ones from forming.
Which hormone most directly increases sebum production in acne-prone skin?
Insulin
Androgens
Estrogens
Cortisol
Androgens stimulate sebaceous glands to increase sebum output, which can contribute to follicular blockage and acne formation. Higher androgen levels are linked to increased severity of acne.
Why are non-comedogenic skincare products recommended for acne-prone skin?
They contain high SPF
They alter skin pH dramatically
They are oil-based
They do not block pores
Non-comedogenic products are formulated to avoid ingredients that clog pores and exacerbate comedone formation. Using them minimizes the risk of new acne lesions.
Which oral antibiotic is considered first-line for moderate inflammatory acne?
Ketoconazole
Clindamycin
Erythromycin
Doxycycline
Doxycycline is a tetracycline antibiotic with anti-inflammatory properties commonly used for moderate inflammatory acne. It reduces Propionibacterium acnes colonization and cytokine production.
How does benzoyl peroxide exert its therapeutic effect in acne?
Releases free radicals to kill bacteria
Blocks androgen receptors
Reduces melanin synthesis
Inhibits 5-alpha reductase
Benzoyl peroxide generates oxygen free radicals that have bactericidal effects on Propionibacterium acnes. It also has mild keratolytic properties that help clear follicles.
What key counseling point should be given when prescribing topical retinoids?
Apply at night and expect dryness
They provide immediate results
Use only in the morning
Avoid using moisturizer
Topical retinoids are photosensitive and can cause irritation, so they are best applied at night. Patients should be counseled about initial dryness and advised to use gentle moisturizers.
Which dietary factor is most strongly associated with worsening acne?
High fiber intake
Omega-3 supplements
Low-fat dairy
High glycemic load foods
High glycemic load foods can trigger insulin and IGF-1 spikes that promote sebum production and follicular hyperkeratinization. Clinical studies link such diets to increased acne severity.
Which scale is commonly used to classify acne severity in clinical practice?
Apgar score
Psoriasis Area Severity Index
Global Acne Grading System (GAGS)
Glasgow Coma Scale
The Global Acne Grading System quantifies lesion types and distribution to assign a severity score. It aids clinicians in standardizing treatment decisions.
What is the primary pathological event that leads to comedone formation?
Lymphocyte infiltration
Follicular hyperkeratinization
Melanin overproduction
Collagen degradation
Follicular hyperkeratinization causes corneocytes to accumulate and block the pilosebaceous canal, forming a comedo. This is the initial step in acne lesion development.
In nodulocystic acne unresponsive to antibiotics, what is the recommended next step?
Add topical salicylic acid
Isotretinoin therapy
Switch to erythromycin
Increase benzoyl peroxide
Isotretinoin is indicated for severe nodulocystic acne that fails to respond to conventional therapies. It reduces gland size, sebum production, and inflammation.
Which side effect is most commonly associated with oral tetracycline antibiotics in acne treatment?
Hyperpigmentation
Excessive dryness
Photosensitivity
Alopecia
Tetracyclines, such as doxycycline, can cause photosensitivity reactions leading to sunburn. Patients should be advised to use sun protection.
Which topical antibiotic monotherapy is most likely to drive bacterial resistance?
Erythromycin benzoyl peroxide combination
Topical retinoid
Clindamycin
Salicylic acid
Topical clindamycin monotherapy can select for resistant strains of Propionibacterium acnes. Combining antibiotics with benzoyl peroxide reduces resistance risk.
What is the most effective maintenance therapy to minimize acne recurrence?
Topical retinoid application
High potency corticosteroid cream
Frequent exfoliating peels
Oral isotretinoin low dose
Topical retinoids normalize follicular epithelial desquamation and prevent new comedone formation. They are commonly used for long-term maintenance after clearing active lesions.
What is the primary mechanism by which isotretinoin reduces acne severity?
Inhibits melanin synthesis
Stimulates collagen deposition
Decreases sebaceous gland size and sebum production
Blocks androgen receptors
Isotretinoin induces apoptosis of sebocytes, leading to reduced gland size and sebum secretion. This addresses the primary etiologic factor in acne development.
Which laboratory tests are essential to monitor before and during isotretinoin therapy?
Complete blood count only
Thyroid function tests
Lipid panel and liver function tests
Renal function panel
Isotretinoin can cause hyperlipidemia and hepatotoxicity, so baseline and periodic monitoring of lipids and liver enzymes are required. Regular checks ensure safe dosing.
How do retinoids modulate keratinocyte differentiation in acne therapy?
By binding to nuclear retinoic acid receptors and altering gene transcription
By blocking histamine receptors in the skin
By directly killing Propionibacterium acnes
By inhibiting 5-alpha reductase in sebaceous glands
Retinoids bind to RAR and RXR nuclear receptors, influencing transcription of genes that regulate cell differentiation and proliferation. This normalizes desquamation and prevents comedo formation.
Combining benzoyl peroxide with a topical antibiotic primarily offers which benefit?
Increases skin pigmentation
Reduces antibiotic resistance development
Enhances systemic absorption
Prolongs antibiotic half-life
Benzoyl peroxide has bactericidal activity and oxidizes bacterial proteins, reducing the ability of Propionibacterium acnes to develop resistance against the antibiotic. This combination improves long-term efficacy.
Which hormonal therapy is most appropriate for female patients with acne and signs of hyperandrogenism?
Spironolactone
Metformin
Minocycline
Isotretinoin
Spironolactone is an anti”androgen that competitively inhibits androgen receptors in sebaceous glands and reduces sebum production. It is commonly used off-label for hormonally driven female acne.
