The aim of this study is to determine the proportion of clinical improvement, the score changing of type 1 interferon selected gene expression, and analysis of transcriptomics profiling in patients with idiopathic uveitis positive IGRA before and after receiving Anti-Tuberculosis Therapy (ATT).
Hopefully, by conducting this research, we are able to provide valid data that demonstrate the advantages/disadvantages usage of Anti-Tuberculosis Therapy in patients with idiopathic uveitis IGRA positive that correlate with type I IFN. This research is a part of our efforts in discovering bio-marker candidates of idiopathic uveitis IGRA positive clinical patients who will benefit from the ATT administration.
Diagnostic of Idiopathic Uveitis IGRA Positive patients were still unclear. This situation happens because it is still can't be explained if the uveitis from the patients was caused by mycobacterium tuberculosis or not which leads to doubtfulness for Anti-Tuberculosis Treatment (ATT). This study aims to help to provide evidence on whether ATT usage for Idiopathic Uveitis IGRA Positive would bring beneficial impact for the patients. This study will try to analyze the data from clinical improvements, Type 1 Interferon changes, and transcriptomics analysis from the patients.
1,170 studies on the registry are indexed under Tuberculosis; 175 are open to participants now.
This study's planned enrollment of 50 is below the median of 253 across 317 observational studies indexed under Tuberculosis.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Subjects who will be recruited to this study are patients who met the criteria described below:
Active inflammation in the past 180 days characterized by the following sign based on SUN Criteria(in at least one eye)
Active inflammation during patient registration, characterized by the following sign based on SUN Criteria (in at least one eye)
Exclusion Criteria:
Note (\^): Testing is conducted within 1-2 weeks prior to enrollment;
As many 10 subjects of the health volunteers are recruited for this study after giving consent. The health volunteers that will be recruited are the subject who met following criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Subjects: idiopathic uveitis with IGRA positive. Examinations: * Clinical improvement examinations at day 0, second week, week 8, month 3, month 6 and month 12. * Blood sampling at day 0, second week, month 6 for analysing type 1 IFN gene expression scoring using RT-qPCR methods.
Drug: Fixed drug combination (FDC) of ATT and Oral steroid
In the first two week, patients receive FDC of ATT only. Oral steroid start to be given in week three. The ATT regiment is continued for up to 6 months or more, in accordance with WHO guidelines. In the first two months the antibiotic combination given consisted of isoniazid (INH), rifampicin, pyrazinamide, and ethambutol. The next four months or continuation phases, the ATT given is rifampicin and isoniazid. The following dosage and administration of oral steroids will be given to patients, according to guidelines from the American Journal of Ophthalmologists (Douglas A. Jabs et al, 2000): Initial dose: 1mg/kg/day, with maximum adult oral dose 60-80 mg/kg and maintenance dose less than or equal to 10 mg/day. The tapering schedule: Over 40 mg/day, decrease by 10 mg/day every 1-2 weeks, 40-20 mg/day, decrease by 5 mg/day every 1-2 weeks, 20-10 mg/day, decrease by 2.5 mg/day every 1-2 weeks, 10-0 mg/day, decrease by 1 to 2.5 mg/day every 1-4 weeks.
Proportion of clinical improvement
Clinical improvement of uveitis patients with IGRA positive after receiving complete Anti Tuberculosis Therapy is measured by using The Standardization of Uveitis Nomenclature (SUN) inflammation degree. Clinical improvement definition is decreasing of inflammation degree up to two degrees or becoming 0 degree. Meanwhile, clinical failure is defined by increasing of inflammation degree or decreasing of inflammation degree up to one degree/ not becoming 0 degree or unchanged degree of first to fourth degree.
Time frame: 0, 14 days, 8 weeks, 3 months, 6 months, and 12 months
The changes of type 1 interferon scoring in selected gene expression
The score changes of type 1 interferon of uveitis patients with IGRA positive are determined by gene expression value of 10 varieties of type 1 interferon using Quantitative Reverse Transcriptase PCR (RT-qPCR) testing.
Time frame: 0, 14 days, 6 months.
Started Oct 2019 (actual). Primary completion is estimated for Jul 2024, 57 months after the start.
Of 122 non-industry observational studies under Tuberculosis, half reached primary completion within 41 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 76. This study's planned 57 months is above that.
Counting every sponsor, half of 134 studies reached it within 36 months; a quarter within 21 and three quarters within 76.
