Efficacy Of Doxycycline & Versus Rifampin In Treatment Of Rhinoscleroma

Phase 1
Conditions
Rhinoscleroma
Interventions
Registration Number
NCT05431673
Lead Sponsor
Assiut University
Brief Summary

The study is conducted To evaluate the Efficacy of Doxycycline (alone and in combination with Ciprofloxacin) as an alternative to the regular regimen in treating rhinoscleroma, especially for cases with contraindication to the use of one or more of the regularly used drugs.

Detailed Description

Rhinoscleroma is a chronic granulomatous disease endemic in many eastern countries including Egypt, Its causative agent is a gram-negative bacillus, Klebsiella rhinoscleromatis. Low socioeconomic populations are the most affected.. There are four known stages of the lesion. The first of which the 'Catarrhal stage' with purulent rhinorrhea, then there is the 'Atrophic stage' with a picture similar to that of atrophic rhinitis. The next is the 'Hypertrophic' or 'Granulomatous' stage where there are bluish red rubbery nodules in any part along the distribution of the disease, and eventually the 'Fibrotic' or 'Sclerotic' stage with stenosis deformity and loss of functions of the parts affected. Examples of commonly used drugs are 'Rifampicin' which is the most commonly used drug exhibits good results but the need for close monitoring for fear of toxicity is the only limitation to its use, Ciprofloxacin' is another Antibiotic with special efficacy as it has good tissue penetration \& produces high concentrations in respiratory tract secretions. Recently 'Doxycycline' has been approved to be used in rhinoscleroma which has the advantage of not only easier dosing but also better patient compliance as it's used for a shorter course (6 weeks) compared to most other drugs.

Primary Outcome Measures
NameTimeMethod
Percentage of patients showing post treatment histopathologic resolution8 months from the start of treatment

Comparing Histopathologic changes pre and post intervention for the 3 groups and the number of participants whose post treatment biopsy show histopathologic resolution will be measued as percentage to the total number of participants in each group

Secondary Outcome Measures
NameTimeMethod
Nasal Symptoms8 months from the start of treatment

All participants will be asked to score 5 nasal symptoms (nasal congestion/obstruction, anterior rhinorrhea, posterior rhinorrhea, loss of smell and facial pain.) from 0 to 4.

0= no symptoms

1. mild symptoms

2. moderate symptoms

3. sever symptoms

4. very sever symptoms this score will be assessed at the screening visit \& follow up visits at 8 weeks , 6 months.

the total five-symptom score obtained will be the sum of the individual symptoms(0-20)
