First Presentation – OcularHistoryJune2006 43 yearold African man OS: painfuleye
First Presentation – OcularExamination OU VA: 1.0/0.63 IOP: 18/48mmHg AC: 2+ cells, post. synechiae
First Presentation – OcularExamination Fundus OU: massive vesselocclusion neovasc. oftheopticdisc smallgranuloma like changes
First Diagnosis Panuveitis with occlusive vasculitis ofunclearorigin
First Presentation – Investigastions chest X-rayand CT: negativ ACE 34 (8-21) HIV, syphilis: negativ thalassemia ß+ (heterocygote) nosicklecellsdetectable
First Presentation – First Treatment Corticosteroids syst. Lasercoagulation Mycophenolate mofetil Avastin Improvement of uveitis
Follow up – First Treatment antiglaucomatous topicaldrugs corticosteroids syst. lasercoagulation
Follow up – After 1 -3 Months improvementofinflammation, lesstheneovascularisation corticosteroids syst. continued lasercoagulation mycophenolate mofetil avastin
Follow up – After 1 to 9 MonthsJuly 2006 to March 2007 neovascularizationof OD red. moreischemiaperipheral more AC cells, IOP increased systemiccorticosteroids, lasercoagulation avastin
Follow Up – After 9 Months • inflammation reduced, but neovascularisation still detectable
Follow Up – After 12 MonthsJune 2007 planned TNF-alpha blockingagents Quantiferon-test: positive
Second Diagnosis panuveitis with occlusive vasculitis probablyof TB origin but noothersignsof TB detectable
Follow Up – After 13 MonthsJuly 2007 PET-CT scan
1. Spiral CT CT 2. PET PET 3. Fusion Combinationof PET and CT
PET-Tracer: FDG (Fluor-18-Desoxyglucosis) • inflammation • tumor „Trapping“
SUV 2.4 PET/CT - Scan KM-CT Fusion PET+CT • enrichmentoftracer in paratracheal lymphnodes • followedbybiopsy
ResultsofBiopsy PCR for TB: negative biopsy: non caseatinggranulomas diagnosis: Sarcoid plannedtherapy: TNF-alpha blockingagents
Phone call after 3 weeks positive TB - culture
Follow Up – After 16 MonthsOctober 2007 start anti-TB treatment
Follow Up – Next MonthsOctober 2007 clinicallystablefindings regressionofneovascularisations occasionally intravitreal bleedings occasionally mild IOP increase
Follow Up – After 22 MonthsApril 2008 back fromAfrica massive increaseofliverenzymes stopof anti-TB treatment due totoxicity
Last Control– After 94 MonthsOctober 2014 VA: 1.0/0.9 IOP: 18/22 mmHg no AC cells, noneovascularisation treatment: topical anti-IOP drugs
Change ofParadigm • TB: Infectiousdiseasecreatestheproblems • but mayinitiate an immune response which mayleadtouveitis • diagnosis: Chest-X-Ray, Mantoux • but in caseof strong suggestionof TB QuantiFERONand PET-CT-Scan with biopsyandculture • problem: immune-mediated (latent?) TB • probablyeverywhere
Implications for Diagnosis • Tuberculosis: • PCR lesseffectiveasculture • specificityofquantiferontestmaybehigherthansuggested in theliterature • Sarcoidosis: • positive biopsynoprooveofsarcoid !! • inducedby TB?
Implicationsfor TB-Treatment • infectious TB • anti TB-treatment • non-infectious (latent, immune-mediated) TB • anti-TB T-cellsexist (+ Quantiferon Test) • despite massive IS: nogeneralisation • anti-TB with immunosuppressives
Immune-mediated TB TBAntigen Ag-Presentation Infectious TB T-Cells B-Cells Uveitis
Conclusion • TB maymimicsarcoiduntilthelevelofbiopsy • infectiousandimmenumediated TB caninduce panuveitis with retinal vasculitis • treatmentconsistsof anti-TB-treatment andprobablyevenimmunosuppressivetreatment
