Topical Lactoferrin and Luliconazole, Alone or in Combination, for Tinea Corporis

8 november 2026 uppdaterad av: Noura Abdelmoneim Mohammed Elseessy, Kafrelsheikh University

Efficacy and Safety of Combined Topical Lactoferrin and Luliconazole Therapy Versus Topical Luliconazole Monotherapy in Egyptian Patients With Tinea Corporis: A Double-Blind Randomized Controlled Trial

This clinical trial will compare three cream treatments for tinea corporis, also called ringworm of the body. It will include Egyptian adults aged 18 to 65 years whose skin infection is confirmed by examining a skin scraping under a microscope.

The main questions are:

  • Does using lactoferrin cream with luliconazole cream clear the infection better than either cream alone?
  • What side effects occur with each treatment?
  • Does the infection return after treatment?

Participants will be assigned by chance to one of three groups:

  • Lactoferrin 2% cream and luliconazole 1% cream.
  • Luliconazole 1% cream and a matching cream without lactoferrin.
  • Lactoferrin 2% cream and a matching cream without luliconazole.

The matching creams contain no active study ingredient and help keep treatment assignments hidden. Participants and the researchers assessing their skin will not know which treatment each participant receives.

Participants will apply their assigned creams twice daily for four weeks. They will attend study visits for skin examinations, symptom assessments, and monitoring for side effects. Skin scrapings will be examined to check whether the infection has cleared. Researchers will also assess changes in the size of the affected areas, itching, treatment satisfaction, and whether the infection returns.

Detaljerad beskrivning

This prospective, randomized, double-blind, parallel-group clinical trial will evaluate the efficacy and safety of topical lactoferrin 2% cream combined with topical luliconazole 1% cream compared with either agent alone in Egyptian adults with tinea corporis.

The study will be conducted at the outpatient clinics of the Department of Dermatology, Venereology and Andrology, Kafrelsheikh University Hospital, Egypt. Diagnosis will be established by clinical examination and confirmed by direct microscopic examination of skin scrapings using a 10% potassium hydroxide preparation. Written informed consent will be obtained before enrollment.

Eligible participants will be randomly assigned in a 1:1:1 ratio to combination therapy, luliconazole monotherapy with a matching lactoferrin vehicle cream, or lactoferrin monotherapy with a matching luliconazole vehicle cream. Participants and outcome assessors will remain unaware of treatment allocation. Active and matching vehicle creams will have identical appearance, consistency, packaging, and labeling.

Participants will apply their assigned creams to the affected areas twice daily for four weeks. In the combination group, lactoferrin cream will be applied before luliconazole cream. The corresponding application sequence will be maintained in the monotherapy groups using the matching vehicle creams. Additional topical or systemic antifungal treatment will not be permitted during the study.

Baseline assessments will include medical and treatment history, disease duration, previous recurrence, lesion number and location, lesion measurements, clinical photography, and assessment of itching. Subsequent assessments will evaluate treatment response, mycological findings, and adverse events.

The primary efficacy outcomes will be clinical cure and mycological cure. Clinical cure will be defined as complete disappearance of erythema, scaling, active lesion borders, and pruritus. Mycological cure will be defined as a negative potassium hydroxide examination.

Secondary assessments will include changes in lesion size, itching severity measured using a 10-cm visual analog scale, categorical clinical improvement, patient satisfaction, and recurrence after treatment. Recurrence will be assessed as clinical and/or mycological reappearance of infection.

Safety monitoring will include burning, erythema, irritation, pruritus, edema, hyperpigmentation, and other adverse events. The severity of adverse events and their relationship to study treatment will be documented.
