简要总结
Sarcoidosis is a granulomatous disease for which the molecular and immunologic association with mycobacteria continues to strengthen. The investigators are interested in conducting a proof-of-concept investigation of the effects of antibiotics on sarcoidosis resolution. The investigators hypothesize that pulmonary sarcoidosis will improve faster if patients are given antimycobacterial therapy, in addition to their standard therapy.

入选标准
- •Subjects with sarcoidosis will be enrolled as defined below.
- •Patients with sarcoidosis as defined by the ATS/ERS/WASOG statement on sarcoidosis as defined by the clinical presentation consistent with sarcoidosis, as well as biopsy finding granulomas, and no alternative for the cause of the granulomas, such as tuberculosis.
- •Evidence of parenchymal disease on chest radiograph (Stage II, III or IV) or Stage I disease by chest radiographs and evidence of abnormal spirometry. . Subjects with concurrent extrapulmonary sarcoidosis, particularly skin and eye involvement, can be enrolled.
- •FVC of >=45% and <=80% of predicted normal value at screening.
- •If female, subject is either not of childbearing potential, defined as postmenopausal for at least 1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy), or is using one of the following methods of birth control for the duration of the study and 90 days after study completion:
- •condoms, sponge, foams, jellies, diaphragm, or intrauterine device
- •contraceptives (oral or parenteral) for three months prior to study drug administration
- •a vasectomized sole partner
- •Females of childbearing potential must have a negative urine pregnancy test at screening visit.
排除标准
- •No consent/inability to obtain consent.
- •Age less than 18 years of age.
- •Inability to draw blood.
- •ALT or AST >5 times upper limit of normal (ULN)
- •Pregnancy or breast feeding.
- •Allergy to macrolides, quinolones or rifamycins.
- •Visual Impairment as defined by differentiating colors per personal history.
- •Family or personal history of long QT syndromes.
- •Patients receiving another interventional investigational drug for sarcoidosis within the 30 days prior to dosing
- •Use of any investigational medication within the past 28 days prior to study enrollment.
- •Subject has been hospitalized for infection or received IV antibiotics within the previous 2 months prior to baseline.
- •Subject has a history of tuberculosis at anytime or close contact with a person with active tuberculosis within the previous 6 months, or persistent or active infections requiring hospitalization or treatment with IV antibiotics, IV antiretrovirals, or IV antifungals within 30 days of baseline, OR oral antibiotics, antivirals, or antifungals for purpose of treating infection, within 14 days of baseline.
- •Subject has an active infection requiring systemic antibiotics at time of screening
- •Subject has a history of listeriosis, treated or untreated tuberculosis, exposure to individuals with tuberculosis.
- •Have a diagnosis of other significant respiratory disorder other than sarcoidosis that would complicate the evaluation of response to treatment
- •Patients otherwise unsuitable for participation in the opinion of the investigator.
- •No smoking for past one year.
研究组 & 干预措施
Antibiotics
Levaquin 750 mg loading on day 1, then 500 mg po QD Ethambutol 15-25 mg/kg for a maximum of 1200mg po QD Azithromycin 500mg on day 1, then 250 mg po QD
**Rifampin 10 mg/kg for a maximum of 600mg po QD or Rifabutin 10 mg/kg for a maximum of 300 mg po QD. **We will not use both, but either one or the other based upon if the patient is on other medications that are metabolized by the cytochrome P450 pathway.
干预措施: levaquin; ethambutol; rifampin and azithromycin. (Drug)
结局指标
主要结局
Change in Absolute FVC From Baseline to Post Completion of 8 Weeks of Antibiotic Therapy.
时间窗: 8 weeks
The primary endpoint was improvement in absolute FVC from baseline to completion of therapy. Spirometry testing was performed using a standardized calibrated laptop spirometer, Flowscreen II USA Spirometer (VIASYS Healthcare Inc., Yorba Linda, CA). The volume accuracy of the spirometer was checked daily using a three liter calibration syringe. Each subject was given at least three attempts and the greatest measurement for absolute FVC and Forced Expiratory Volume (FEV1) at baseline, four week, and eight week assessments was recorded.
