The Efficacy of Prednisone and Azithromycin in the Treatment of Patients With Cat Scratch Disease
A Phase 4 study testing prednison and azithromycin, prednison, azithromycin and prednison, Azenil in people with Cat-scratch Disease and Bartonella Infections, run by Tel-Aviv Sourasky Medical Center at 1 site in Israel.
Trial summary
Bartonella henselae is the etiologic agent of cat scratch disease (CSD). 90% of patients present with regional lymphadenitis (typical CSD) while 10% will have disease involving other organs, such as neuroretinitis, arthropathy, erythema nodosum, and encephalitis (atypical CSD).

About this study
Official title: Open Label Study of Prednisone and Azithromycin in the Treatment of Patients With Cat Scratch Disease
Bartonella henselae is the etiologic agent of cat scratch disease (CSD). 90% of patients present with regional lymphadenitis (typical CSD) while 10% will have disease involving other organs, such as neuroretinitis, arthropathy, erythema nodosum, and encephalitis (atypical CSD). In most CSD cases resolution occurs in 2 to 3 months although a prolonged course often occurs. Data on the efficacy of antibiotic therapy in CSD is limited. Azithromycin has been shown to have a small favorable effect in a small comparative study and is commonly prescribed for CSD, however its overall effect is not satisfactory. Corticosteroids may be effective in the treatment of CSD for the following reasons:
- Many experts believe that host response is involved in the pathogenesis of CSD and is responsible for the clinical manifestations rather than the direct effect of B. henselae. The absence of viable organisms in affected lymph nodes (in the presence of positive PCR for B. henselae DNA), and the fact that arthritis, arthralgia and erythema nodosum (that are often associated with autoimmune diseases) have been described in CSD, support this concept.
- Corticosteroids have been anecdotally reported to have been administered to patients with CSD, apparently with some success. The purpose of this study is to evaluate the efficacy of corticosteroids in addition to azithromycin in CSD. The study hypothesis is that corticosteroids will improve out come. Ten patients with typical CSD will be treated with a 5-day oral course of prednisone (1 mg/kg up to 60 mg/day) and azithromycin (500 mg on day 1 and 250 mg on days 2-5). Patients will be under followed up for 3 months. Major outcome measures will include duration of symptoms and signs, with particular emphasis on affected lymph node size and duration using a specific scoring system (lymphadenitis score, LS). LS will be used to evaluate lymphadenitis at each follow-up visit. The time period from baseline LS until 75% and 90% reduction in LS in the treatment group will be compared with historical controls. The historical control group will be consisted of age, sex, and clinical manifestations-matched CSD patients who were treated with azithromycin without corticosteroids.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
prednison and azithromycinDrug
Patients with typical cat-scratch disease will be treated with a 5-day course of prednison and azithromycin.
prednison, azithromycinDrug
Cap Azithromycin 500 mg qd (first day), then 250 mg qd for 4 days and Tab prednison 1 mg/kg/day, not exceeding 60 mg/day, qd, for 5 days.
prednison, AzenilDrug
Cap Azenil 500 mg qd (first day), then 250 mg qd for 4 days and Tab prednison 1 mg/kg/day, not exceeding 60 mg/day qd, for 5 days.
What is being measured
The primary outcome is the main question the study is designed to answer.
Severity score of lymphadenitis using a lymphadenitis Score (LS).
LS will evaluate the severity of lymphadenitis, using the following clinical parameters: size of lymph node in cm; pain estimated by the patient, using a 0-5 scale (0 equals no pain, 5 the most severe pain); tenderness estimated by the physician, (0 equals no tenderness, 5 the most severe tenderness); erythema of the skin overlying the affected lymph-node (0 no erythema, 1 mild erythema, 2 moderate erythema and 3 severe erythema); suppuration of a lymph node will score 5 points, no suppuration will score 0. The total score will consist of the arithmetical summation of the 5 parameters.
Measured: Change from baseline in LS until 75% and 90% reduction in LS

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing prednison and azithromycin, prednison, azithromycin and prednison, Azenil in people with Cat-scratch Disease and Bartonella Infections, run by Tel-Aviv Sourasky Medical Center at 1 site in Israel.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 11 Nov 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Severity score of lymphadenitis using a lymphadenitis Score (LS). (time frame: Change from baseline in LS until 75% and 90% reduction in LS). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Nov 2011.
