Presentation reference

Is it this?

Reference only, to read alongside your own examination.

Signs — what you find (6)

  • One or more toenails, usually a great toenail, appear thickened and discolored
  • Mild dry, scaly skin on the sole is often overlooked concurrent tinea pedis, mistaken for simple dryness [scaling]
  • Distal lateral subungual onychomycosis shows partial lifting of the nail from its bed with thickening or crumbling underneath
  • White superficial onychomycosis appears as chalky white deposits on the nail surface
  • Total dystrophic onychomycosis, the most advanced form, shows heavy thickening under the nail with destruction of the nail plate and bed ridging
  • Dermoscopy showing fine spikes and lengthwise streaks under the nail points to fungal infection rather than simple nail dystrophy

Tests (5)

  • A potassium hydroxide wet-mount of nail scrapings is only about 60% sensitive, but a positive result can separate a true fungus from a contaminant
  • A PAS-stained nail clip biopsy read by a pathologist is the most sensitive test, at about 95%
  • Fungal culture is very specific but only around 60% sensitive, and results take weeks to grow
  • PCR testing raises dermatophyte detection by about 20% compared with culture alone
  • Roughly half of abnormal-looking toenails turn out not to be fungal, so mycology testing is needed before treating

If not this — what else fits (6)

  • Yellow nail syndrome is named as a mimic of onychomycosis
  • A drug reaction can produce nail changes resembling fungal infection
  • Hypothyroidism is listed among the conditions that can resemble onychomycosis
  • Nail malignancy must be distinguished from onychomycosis
  • Psoriatic nail changes are on the differential for onychomycosis
  • Contact dermatitis of the nail fold is on the differential

TERBINAFINE

1st line

Formoral.solid

Adult dose and duration

250 mg orally once daily. x 6 weeks for a fingernail infection, or 12 weeks for a toenail infection.

Paediatric dose

Paediatric dosing is specialist-set and is not reproduced here.

Dose source

Egyptian National Drug Formulary - antimicrobial-2023.pdf, Terbinafine monograph (chapter PDF p415)

Why

Terbinafine is the formulary's oral first-line agent for dermatophyte onychomycosis, the most common cause of thickened, discoloured nails, and its own text notes other agents are preferred only when the cause is not a dermatophyte.

Cautions
  • Confirm the diagnosis with nail clipping microscopy/culture before committing to a multi-week course.
  • Hepatotoxicity risk - baseline and periodic liver function tests are advisable for a course this long; avoid in active liver disease.
  • A diabetic patient with nail or surrounding skin infection needs closer monitoring for complications.
  • Spreading cellulitis around the nail needs antibacterial treatment and reassessment, not an antifungal alone.

ITRACONAZOLE

2nd line

Formoral.solid

Adult dose and duration

Continuous dosing: 200 mg orally once daily for 6 weeks or 12 weeks. Alternative pulsed dosing: 200 mg orally twice daily for 1 week, repeated every 4 weeks, for 2 months or 3 months. x 6 or 12 weeks continuous, or 2 or 3 pulsed months — the formulary gives both figures without saying which nail gets which

Paediatric dose

Paediatric dosing is specialist-set and is not reproduced here.

Dose source

Egyptian National Drug Formulary 2023 — Antimicrobial, Itraconazole monograph, Onychomycosis (antimicrobial-2023.pdf, page index 55, printed p46)

Why

The formulary itself notes other agents (i.e. terbinafine) are preferred for dermatophyte onychomycosis, making itraconazole the second-line oral option, useful when terbinafine is unsuitable or the infection is non-dermatophyte.

Cautions
  • Capsules and oral solution are not interchangeable; give capsules after food, swallowed whole, and not with antacids.
  • Obtain liver function tests in patients with pre-existing liver disease and in anyone treated for longer than a month.
  • Contraindicated for onychomycosis in anyone with ventricular dysfunction or a history of congestive heart failure, and in women who are pregnant or contemplating pregnancy.
  • The formulary notes other agents are preferred for dermatophyte onychomycosis.
  • The formulary does not state which duration is for fingernail and which for toenail. Longer courses are conventionally used for toenail, but the formulary does not say so.
  • Numerous drug interactions via CYP3A4 (some statins, benzodiazepines, and other drugs) - review all concurrent medications before prescribing.
  • Contraindicated in heart failure with reduced ejection fraction; discontinue if signs or symptoms of heart failure occur.
  • Hepatotoxicity risk - monitor liver function on longer or repeated courses.
  • Avoid in pregnancy.
  • A diabetic patient with nail or surrounding skin infection needs closer monitoring for complications.
