The reported incidence of uveitis is 52 persons per year per 100,000 population, with a greater incidence estimated in developing countries, including Indonesia. Uveitis has challenges in diagnosis and therapy, due to the existence of an immunological privilege mechanism, so it is not easy to obtain diagnostic markers or provide appropriate therapy. In uveitis, a work-up examination looking for signs in the entire body or systemic disease is often conducted.
Up until today, establishing the diagnosis of tuberculosis (TB)-associated uveitis is still a challenge. From histopathological studies, TB germs are difficult to find. Wreblowski et al. found that paucibacillary conditions also made TB bacteria difficult to find by PCR and tuberculin test results were also not completely reliable. The development of IGRA (Interferon-Gamma Release Assay) assays, such as QuantiFERON-Gold TB (QFT) has been investigated. Our previous study found that IGRA-positive uveitis patients with type 1 IFN gene expression score >5.61 were more likely to have active TB uveitis. In addition, serum C1q examination also showed an inverse correlation with this score.
Regarding therapy, until now corticosteroids and cycloplegics are the mainstay treatment for uveitis. However, appropriate administration of anti-infective drugs is necessary in cases of infection. Inflammation in TB-associated uveitis is thought to be the result of the immune response that occurs as a result of paucibacillary TB infection. Examinations can be redundant and problematic. Determination of therapy is also a dilemma because it is difficult to determine the right patient candidate for administration of anti-tuberculosis therapy (ATT). The protocol of ATT administration itself has not been standardized so it often follows the extra pulmonary TB protocol and there has been no reliable clinical trial research on ATT administration in patients with suspected TB uveitis yet no TB microorganisms are found directly in the eyes or other organs.
On this basis, the investigators planned a prospective randomized clinical trial study that involve idiopathic uveitis patients with positive IGRA test, to assess the effectivity of ATT compared to oral steroids. In addition, this study can also be used as a basis for validation of type 1 IFN scores and serum C1q as diagnostic/prognostic biomarkers in cases of TB-associated uveitis.

Dosage form: ATT fixed-dose combination (FDC). FDC intensive phase containing 150 mg of rifampicin, 75 mg of isoniazid not 300mg, 400 mg of pyrazinamide, and 275 mg of ethambutol, while FDC continuation phase containing rifampicin-isoniazid. Dosage: according to body weight, 30-37 kg: 2 tablets, 38-54 kg: 3 tablets, 55-70 kg: 4 tablets, more than 70 kg: 5 tablets. Frequency: Intensive phase: once daily. Continuation phase: 3 times/week. Duration: 9 months (2 months of FDC intensive phase + 7 months of FDC continuation phase)
Drug: Anti Tuberculosis Drug
Local steroids were prescribed according to the standard care by the attending uveitis specialists and tailored to the severity of the intraocular inflammation. Additionally, all participants in this group received oral methylprednisolone at a dosage of 0.8 mg/kg of body weight per day (maximum of 56 mg/day), which was tapered gradually based on the intraocular inflammation observed. Tapering of oral methylprednisolone involved reducing the dose by 8 mg for doses above 20 mg and by 4 mg for doses below 20 mg.
Drug: Methylprednisolone
ATT will be given in the form of fixed drug combination (FDC). Each patient will get a regimen of 2RHZE (2 months of FDC intensive phase, which contains of Rifampicin, Isoniazide, Pirazinamide, Ethambutol) + 7RH (7 months of FDC continuation phase, which contains of Rifampicin and Isoniazid). The dosage will be according to body weight, 30-37 kg: 2 tablets, 38-54 kg: 3 tablets, 55-70 kg: 4 tablets, more than 70 kg: 5 tablets. FDC drugs have to be consumed daily during intensive phase and three times a week during continuation phase.
Selected participants may be prescribed local or systemic immunosuppressants, including oral methylprednisolone, starting at a dosage of 0.8 mg/kg of body weight per day and tapered gradually (e.g., every three days or weekly) based on the severity of intraocular inflammation observed during presentation and follow-up visits.
Percentage of Treatment Failure
Treatment will be categorized as a failure if subject did not meet the following criteria at the 6-month follow-up post initial therapy, (1) less than or equal to 0.5+ anterior chamber cells by SUN criteria, less than or equal to 0.5+ vitreous haze clinical grading using the NEI scale, and no active retinal or choroidal lesions; and (2) no more than 7.5 mg of oral prednisone daily and less than or equal to 2 drops of prednisolone acetate 1% (or equivalent) per day; or in other words, the subject has persistent inflammation that keeps getting worse.
Time frame: 6 months after the initial therapy
Response to Treatment
Criteria for complete uveitis resolution applied to both eyes, in cases with bilateral uveitis, included: (1) fewer than or equal to 0.5+ anterior chamber cells according to the Standardized Uveitis Nomenclature (SUN) grading system, fewer than or equal to 0.5+ vitreous haze based on clinical grading using the NEI (National Eye Institute) scale, and no active retinal or choroidal lesions; and (2) no more than 7.5 mg of oral prednisone daily (i.e., methylprednisolone at 6 mg or less daily) and fewer than or equal to 2 drops of prednisolone acetate 1% (or equivalent) per day. Treatment will be categorized as a failure if subject did not meet the following criteria at the 6-month follow-up.
Time frame: 6 months after initial treatment
Time to Uveitis Resolution
Calculated from the time of randomization. These criteria had to be maintained for at least 90 days following the visit when the first complete uveitis resolution was recorded. If there was insufficient follow-up after resolution, maintained uveitis resolution was still considered. Participants who met criterion 1 but not criterion 2 were classified as having partial uveitis resolution (non-complete uveitis resolution). This was measured every visit using objectives of ophthalmologist's clinical judgement from slit-lamp examination and clinical complaints.
Time frame: 90 days after the visit of first uveitis resolution was recorded
Uveitis Relapse
Uveitis relapse was defined as any worsening of ocular inflammation (including a two-step increase in anterior chamber or vitreous cells as per the SUN grading system) or the occurrence of clinically new inflammatory activity (such as choroidal or retinal lesions) that necessitated a modification of local or systemic uveitis treatment after a minimum of 90 days of complete uveitis resolution at the patient level. Time to relapse was calculated from the first visit showing inactive uveitis until the first notification of uveitis relapse.
Time frame: 6 months after the initial therapy
Eye-Level outcome (Visual Acuity)
The differences in visual acuity between baseline and month 6.Visual acuity was considered to increase if the difference in best-corrected visual acuity between month 6 and baseline visits (measured with Snellen, in decimal equivalent) was equal to or greater than 0.1, stable if within the range of -0.1 to 0.1, and decreased if less than -0.1. If any cataract or vitreoretinal surgery was performed before the six-month follow-up, the last recorded visual acuity prior to the surgery was used.
Time frame: 6 months after baseline visit
Eye-Level outcome (Secondary glaucoma)
The incidence of secondary glaucoma (e.g., occurrences of increased intraocular pressure (IOP) above 21 mmHg in at least two consecutive visits that necessitated prescription of IOP-lowering medications).
Time frame: 6 months after baseline visit
Ran from Aug 2021 to primary completion in Oct 2024, 37 months.
Of 43 non-industry phase 2 interventional studies under Tuberculosis, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 37. This study's 37 months is above that.
Counting every sponsor, half of 63 studies reached it within 24 months; a quarter within 15 and three quarters within 36.
