Efficacy of Doxycycline in the Treatment of Early Stages of Mycosis Fungoides

Overview

Current study aims at assessing the efficacy of doxycycline as a potential treatment modality for early stages of MF.

Objectives Objective is to evaluate the efficacy of doxycycline in treatment of early stages of mycosis fungoides (IA, IB and IIA) and to assess its apoptotic enhancing effect by studying the expression of BCL2 by the T lymphocytes. Study Design Randomized controlled trial Population of study \& disease condition 30 patients with early stage mycosis fungoides (Stage Ia,Ib and IIa) Methodology in details After signing an informed consent, each participant will be subjected to: I. Baseline evaluation: 1. Baseline biopsy to document the current state of the disease and to assess immunohistochemically the expression of CD3 and Bcl2 by the lymphocytes. 2. Detailed history taking including onset, course, duration of the disease and history of any previous treatments used. 3. Detailed examination of skin lesions and scoring using: * Modified Severity of Index Weighted Assessment (mSWAT) * Composite Assessment of Index Lesion Severity (CAILS) 4. Pruritus scoring using a visual analog scale from 0-10, where 0=no pruritus and 10=worst imaginable pruritus 5. Photography II. Treatment and dosing protocol: Participants will be randomly allocated in either one of the treatment groups: Group A: Will receive oral doxycycline in a dose of 200 mg daily for three months. Group B: Will receive PUVA with dosing \& increments according to the standard protocols of the Phototherapy Unit, Dermatology Department, Cairo University; 3 sessions per week for 3 months. III. Timings of follow up visits and clinical assessments done: Patients will be regularly assessed at weeks 4, 8, and 12. Patients continuing for another three months, as mentioned above, will be assessed at weeks 16, 20 and 24. The following will be done at these follow up visits: mSWAT, CAILS, pruritus scoring and photography. Side effects will be monitored and managed accordingly. IV. Follow up biopsies: A repeat biopsy will be taken at initial improvement in CAILS (or at week 12) for immunohistochemical re-assessment of the expression of CD3 and Bcl2 by the lymphocytes.
