Abstract
PURPOSE To report the occurrence of acute posterior multifocal placoid pigment epitheliopathy (APMPPE)-like posterior uveitis as part of the ocular manifestation of tubulointerstitial nephritis and uveitis (TINU) syndrome. METHODS A 54-year-old previously healthy woman received oral ibuprofen and dipirone because of high fever and malaise. Three days after being started on this treatment, she developed bilateral posterior uveitis resembling APMPPE accompanied by anterior segment inflammation in the context of acute renal nephritis and maculopapular skin rash probably related to drug exposure. RESULTS The patient was hospitalized because of acute renal failure and received support therapy and topical steroids in both eyes. A renal biopsy was not performed (based on good clinical response), but she fulfilled the clinical criteria of acute interstitial nephritis and TINU. Although her renal and ocular functions improved in the first week, she needed to be readmitted days later because of fever and generalized edema and received steroid pulse therapy. Fluorescein angiography was consistent with an APMPPE-like pattern and optical coherence tomography showed neither macular edema nor subretinal fluid. The ocular picture improved during the following weeks with fundus changes resembling those of APMPPE. CONCLUSION Although anterior uveitis is considered the typical ocular component of TINU syndrome, posterior uveitis resembling APMPPE may also be its ocular manifestation.

Abstract
PURPOSE To describe chorioretinal lesions in pediatric uveitis that are associated strongly with the HLA-DR, DQ class II type associated with tubulointerstitial nephritis and uveitis (TINU). DESIGN Retrospective, observational case series. METHODS SETTING University-based clinic. PATIENT POPULATION Fifteen consecutive patients with onset of bilateral panuveitis at less than 16 years of age who were seen between September 2004 and October 2012 and 6 pediatric patients with confirmed TINU. OBSERVATION PROCEDURE HLA-DR, DQ class II DNA typing. MAIN OUTCOME MEASURE Detection of the HLA-DRB1*01 and HLA-DQB1*05 risk alleles for TINU. RESULTS Fourteen (93%) of the 15 patients with otherwise unexplained pediatric panuveitis typed HLA-DRB1*01-HLA-DQB1*05. Eleven (73.3%) of 15 patients had bilateral sharply demarcated, usually inferior, 200- to 300-μm spots of chorioretinal atrophy, and 4 (27.7%) of 15 patients had bilateral clusters of 500- to 750-μm poorly defined orange choroidal lesions without overlying atrophy of the retinal pigment epithelium. None had interstitial nephritis. Four of the 6 definite TINU cases had class II typing and TINU risk alleles; all 6 had bilateral panuveitis. The frequency of risk alleles was statistically higher in those with pediatric panuveitis than in the North American population and in nonpanuveitis pediatric uveitis patients assumed to have the North American HLA distribution (P < .0001, Fischer exact test). Positive likelihood ratios were 9.92 to 5.18, depending on assumptions regarding pretest probability of disease. CONCLUSIONS Recognition of characteristic chorioretinal lesions in otherwise unexplained pediatric panuveitis, supported by selective HLA class II DNA typing, is useful in narrowing diagnostic possibilities and directing further evaluations. Panuveitis is underappreciated as a manifestation of TINU.

Abstract
The human leukocyte antigen (HLA) genotype has been shown to associate with tubulointerstitial nephritis (TIN) and tubulointerstitial nephritis with uveitis syndrome (TINU). The association of HLA genes with TIN was examined in this nation-wide study. HLA genotyping was performed in 31 pediatric patients with biopsy-proven TIN. All patients were examined by an ophthalmologist to diagnose possible uveitis. Class II HLA genotypes of TIN patients were compared with the Finnish reference population. We found a significant association between the HLA alleles DQA1*04:01 [risk ratio (RR) 5.0, 95% confidence interval (CI) 2.0-11.2], DQB1*04:02 (RR 2.7, 95% CI 1.4-5.3), and DRB1*08 (RR 3.8, 95% CI 1.5-8.4) and TIN. Uveitis was found in 20/31 (64.5%) patients. HLA genotyping of the TINU patients showed additional risk HLA alleles: DQA1*01:04 (RR 6.1, 95% CI 1.5-17.8), and DRB1*14 (RR 8.2, 95% CI 2.2-22.1). The alleles DQA1*01:04 (RR 8.8, 95% CI 2.2-26.5), DQA1*04:01 (RR 3.2, 95% CI 1.2-7.3), and DRB1*14 (RR 12.0, 95% CI 3.2-33.0) were more frequent in patients with TIN and chronic uveitis than in reference population. The HLA class II haplotype DQA1*04:01/DQB1:04:02/DRB1*08 was the most common combination in our study population (58.1%). None of the patients had haplotype DQA1*04:01/DQB1*06:02/DRB1*15, which is common in Finland. HLA genotype did not predict the renal outcome. We found a strong association between certain HLA genotypes both in TIN and TINU patients. The TIN/TINU-associated HLA alleles appear to vary depending on study population.

Tubulointerstitial nephritis and uveitis syndrome in a twelve-year-old girl. Case Rep Pediatr 2013; 2013:652043.

Abstract
Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disorder defined by the combination of biochemical abnormalities, tubulointerstitial nephritis, and uveitis. We describe a 12-year-old female, presented with a ten-day history of fever, characterized by sudden onset and rapid spontaneous resolution in few hours, accompanied by shivering, extreme fatigue, and loss of appetite. Laboratory values were consistent with renal failure of tubular origin. Renal biopsy confirmed a tubulointerstitial nephritis, with acute tubulitis, polymorphonuclear infiltration, and microabscesses. The renal interstitium was occupied by a dense inflammatory infiltrate, consisting of lymphocytes, plasma cells, and neutrophils. Glomerular structures were preserved. Ophthalmological examination that suggested a previous asymptomatic bilateral uveitis and HLA typing (HLA-DQA1∗0101/0201 and HLA-DQB1∗0303/0503) further supported the suspect of TINU syndrome. TINU syndrome is probably an underdiagnosed disorder, responsible for many cases of idiopathic anterior uveitis in young patients, especially in those who have asymptomatic renal disease and when proper diagnostic tests are not performed at the time of presentation.

Abstract
PURPOSE To evaluate the occurrence and characteristics of uveitis related to tubulointerstitial nephritis (TIN) in children. DESIGN Prospective, observational, multicenter, partly placebo-controlled treatment trial. PARTICIPANTS Nineteen children with a biopsy-proven TIN. METHODS Patients were treated with prednisone or followed without treatment. In addition to the nephrologic evaluations, the prospective follow-up included structured ophthalmological examinations at the onset of TIN and at 3 and 6 months after the diagnosis. MAIN OUTCOME MEASURES Occurrence, clinical features, and outcome of uveitis. RESULTS Some 84% (16/19) of the patients had uveitis, 83% (5/6) in the nontreatment group and 82% (9/11) in the prednisone-treated group. The remaining 2 patients, originally in the nontreatment group, were switched to the prednisone group after 2 weeks. Both of them developed uveitis. Altogether, 3 patients developed uveitis during prednisone treatment and 2 patients showed worsening of uveitis despite the systemic corticosteroid. Some 50% (8/16) of the patients with uveitis presented with no ocular symptoms; 88% (14/16) of the patients had a chronic course of uveitis. Two patients were diagnosed with uveitis before nephritis; nephritis and uveitis were diagnosed within 1 week from each other in 7 patients, and uveitis developed 1 to 6 months after the diagnosis of TIN in 7 patients. CONCLUSIONS There was no statistically significant difference in the occurrence of uveitis in patients with TIN in the prednisone and nontreatment groups. In this study, the occurrence of uveitis associated with TIN was considerably higher than previously reported. Uveitis related to TIN may develop late and is often asymptomatic. The ophthalmological follow-up of all patients with TIN is warranted for at least 12 months starting with 3-month intervals.

Abstract
The tubulo-interstitial nephritis and uveitis (TINU) syndrome, first described in 1975, is a rare disease most probably of autoimmune origin that is characterized by unilateral or bilateral uveitis and tubulointerstitial nephritis. Most patients are adolescents and it is sometimes associated with other autoimmune diseases, such as spondyloarthritis, rheumatoid arthritis and hyperthyroidosis. This article reports the case of a 43-year-old female patient who presented with refractory recurrent bilateral uveitis despite therapy with high doses of corticosteroids in combination with cyclosporin. When the patient was referred to this hospital for rheumatological examination after almost 1 year of therapy, mild renal insufficiency and proteinuria were found. The kidney biopsy revealed interstitial nephritis, partly crescent-shaped and partly chronic. A diagnosis of TINU syndrome was made and treatment with adalimumab in combination with methotrexate was started. The favorable clinical outcome indicated that tumor necrosis factor (TNF) alpha may play an important role in the pathogenesis of TINU syndrome.

Abstract
Purpose. Tubulointerstitial nephritis and uveitis (TINU) syndrome usually shows anterior segment intraocular inflammation, but severe posterior segment intraocular inflammation is rarely observed. We report 2 children with TINU syndrome complicated by subfoveal choroidal neovascularization (CNV). Methods. Case reports. Results. Patients were a 12-year-old girl and a 12-year-old boy diagnosed with probable TINU syndrome on the basis of typical ocular findings and high value of urinary β2 microglobulin even though renal biopsy was not performed. The girl showed development of CNV with subretinal macular hemorrhage along with the exacerbation of anterior chamber inflammation in her left eye. Subretinal macular hemorrhage recurred frequently even with oral prednisolone; therefore, intravitreal injection of bevacizumab (IVB) was performed. After IVB, the subretinal proliferative tissue shrunk and subretinal hemorrhage has not recurred for 5 years. The boy showed subretinal hemorrhage from CNV with severe anterior chamber inflammation in his left eye. With oral prednisolone, anterior chamber inflammation and subretinal hemorrhage disappeared, but shrunken subretinal fibrosis in the macula remained. Final visual acuity was poor due to residual subretinal fibrosis in both cases. Conclusions. Tubulointerstitial nephritis and uveitis syndrome has a potential to develop CNV that leads to severe visual loss; therefore, prompt anti-inflammatory therapy is required, and IVB should be regarded as a potential choice of treatment.

Abstract
Tubulointerstitial nephritis and uveitis (TINU) syndrome is a rare disease entity usually occurring in children. In the present study a case of TINU syndrome in an elderly patient is described and relevant literature is reviewed. A 61-year-old man presented with bilateral flank pain, urinary frequency, and foamy urine. A kidney ultrasonography revealed an increase in kidney parenchyma echogenicity. Following a kidney biopsy, the patient was diagnosed with acute tubulointerstitial nephritis. An ophthalmology examination initially performed for floater symptoms, revealed anterior uveitis in both eyes. Acute tubulointerstitial nephritis and anterior uveitis in both eyes responded to treatment with oral prednisolone, furosemide, carvedilol, and a topical steroid. TINU syndrome can occur in the elderly and should be part of the differential diagnosis when seeing a patient who has uveitis in association with renal disease; any therapy should be managed by both an internist and an ophthalmologist.

Abstract
A 32 year-old woman was referred from the Ophthalmology Department to rule out a possible systemic disease. Her only past medical history of relevance was a tuberculosis contact during childhood. She complained of floaters and progressive blurring of vision in both eyes for some months, as well as arthralgia and cough. Her visual acuity was 0.3 in the right eye and 0.4 in the left eye. Biomicroscopy showed bilateral anterior granulomatous uveitis (1+ cells). Funduscopy showed bilateral vitritis 3+, snow banking and peripheral phlebitis. Fluorescein angiography did not show central vasculitis, and optical coherence tomography showed bilateral cystoid macular oedema. Fundus autofluorescence was normal. How would you initially assess this patient in order to decide which systemic examination should be performed, bearing in mind the ophthalmological manifestations?

Abstract
Tubulointerstitial nephritis with uveitis (TINU) syndrome is an unusual and under diagnosed cause of acute interstitial nephritis. The interstitial nephritis may precede, follow or develop concurrent to the uveitis. About 200 cases have been reported worldwide with only a single case reported from India. We report a 16-year-old male with TINU syndrome.

Abstract
Acute idiopathic tubulointerstitial nephritis (TIN) is considered a condition with a good long-term prognosis. However, there is evidence that some patients develop permanent renal impairment. The aim of this study was to evaluate the clinical characteristics of TIN at the time of diagnosis in children and determine whether the findings upon presentation predict renal outcome. The clinical data and biopsy findings from 26 children with idiopathic TIN admitted to four Finnish university hospitals were analyzed retrospectively. Twenty-five patients (96%) manifested renal insufficiency. After the mean follow-up time of 2.75 years (SD 2.5; 0.9-13.5), 4 patients (15%) had permanent renal insufficiency and 8 patients (31%) had persistent low-molecular weight proteinuria. Uveitis was found in 12 patients (46%). Four of these patients (33%) developed chronic uveitis. Our analysis showed that none of the laboratory or biopsy findings upon presentation prognosticated renal outcome. No correlation between renal disease and uveitis could be found either. The occurrence of uveitis among TIN patients was higher than previously reported. Uveitis may develop late and without recurrence of renal dysfunction. Therefore, follow-up by a pediatrician and by an ophthalmologist is warranted in children with acute TIN for at least 12 months from diagnosis.

Abstract
PURPOSE We aim to describe the first case of tubulointerstitial nephritis and uveitis (TINU) syndrome reported in Scandinavia and to underline the importance of the syndrome, which should be better known among ophthalmologists. METHODS We report an 11-year-old boy who was admitted to hospital because of general fatigue and weight loss. Blood tests showed renal insufficiency and a renal biopsy revealed acute tubulointerstitial nephritis. One week after admission the patient developed transitory blurred vision and flickering shadows in the left eye. Slit-lamp examination revealed bilateral anterior non-granulomatous uveitis and TINU syndrome was diagnosed. RESULTS Because of renal insufficiency the patient was treated with systemic prednisone 50 mg/day for 3 weeks. Evolution was favourable, and prednisone was tapered over 10 weeks. Uveitis was treated with topical steroid with good effect. The only complication after 18 months of follow-up was transitory cushingoid aspect. CONCLUSIONS Tubulointerstitial nephritis and uveitis syndrome is a rare syndrome that is probably underdiagnosed in clinical practice. Co-operation between ophthalmologists and nephrologists/paediatricians is crucial for early diagnosis and instigation of treatment. Uveitis may occur before tubulointerstitial nephritis or the renal symptoms may be so mild that the patient is unaware of them. Therefore, ophthalmologists play an important role in the initial discovery of patients with TINU syndrome. Tubulointerstitial nephritis tends to be self-limiting, whereas uveitis tends to relapse and recurrences tend to be more severe than the initial uveitis. Therefore, the patient must be ophthalmologically monitored very carefully.

Abstract
Uveitis is a manifestation of complex processes that can represent an infectious process or a dysfunction of the immune system that may have grave effects on the eye. Although infectious causes, once properly identified, may be successfully treated by addressing the inciting organism with recognized interventions, the immune-modulated chronic forms of uveitis often provide more complex challenges in management. Recent strides in understanding the inflammatory pathway and better bioengineering capabilities have resulted in some new modalities of treatment.

Abstract
PURPOSE Tubulointerstitial nephritis and uveitis syndrome (TINU) is a specific form of uveitis that is unfamiliar to most ophthalmologists. Thus, it is frequently overlooked in differential diagnosis. We hypothesized that recognition of subsets of uveitis can facilitate the diagnosis of rare entities such as TINU. DESIGN Retrospective case series. PARTICIPANTS One thousand nine hundred eighty-five patients with uveitis. METHODS We performed a computerized database analysis of patients evaluated for uveitis at the Casey Eye Institute from September 1985 until May 2005. The database includes details about ocular inflammation, including specific diagnosis, anatomic location, laterality, continuity, onset, complications, HLA-B27 status, and relative diagnostic certainty. Additionally, we reviewed all charts of patients diagnosed with TINU or with a presentation of uveitis that was typical of TINU (i.e., bilateral sudden-onset anterior uveitis). MAIN OUTCOME MEASURES Prevalence of TINU in identifiable subsets of patients with uveitis, visual acuity (VA), and renal function. RESULTS Individuals with TINU (n = 33) represented 1.7% of all patients with uveitis. However, TINU was diagnosed in 32 of the 316 patients (10%) presenting with bilateral sudden-onset anterior uveitis and in 20 of 62 of these patients (32%) who were younger than 20 years. Creatinine levels were more likely to be elevated in patients older than 40. Most patients maintained excellent VA and did not develop clinically significant renal impairment. CONCLUSION Tubulointerstitial nephritis and uveitis syndrome is a common cause of uveitis among patients who present with bilateral sudden-onset anterior uveitis. The size of this series clarifies the understanding of the relationship between renal and ocular disease; facilitates recognition of the syndrome; and adds to the knowledge on prognosis, complications, and role of antecedent medications.

Abstract
BACKGROUND Tubulointerstitial nephritis and uveitis (TINU) syndrome is characterized by a combination of idiopathic acute tubulointerstitial nephritis and uveitis. Krebs von den Lunge-6 (KL-6) is a human glycoprotein secreted by type II alveolar cells in the lung, and its serum levels increase in patients with pneumonia of various causes, as well as ocular sarcoidosis. The aim of the present study is to quantify serum KL-6 levels in patients with TINU syndrome, which has no pulmonary and sarcoid lesions, and elucidate the usefulness of KL-6 for the diagnosis and follow-up of this syndrome. METHODS Serum and urinary samples were obtained from 17 patients with TINU syndrome and 36 age-matched patients with uveitis from other causes. Sarcoidosis was eliminated because serum KL-6 levels increased during their lung lesion. Serum KL-6 level was determined by using a human KL-6 electrochemiluminescence immunoassay. Formalin-fixed paraffin-embedded renal tissue sections were incubated with anti-KL-6 monoclonal antibody, then examined immunohistochemically. RESULTS Mean serum KL-6 levels for patients with TINU syndrome and those with uveitis from other causes were 363.35 +/- 51.06 and 213.19 +/- 10.28 U/mL, respectively (P < 0.001). Urinary beta(2)-microglobulin levels of patients with TINU syndrome and uveitis from other causes were 4.06 +/- 1.31 and 0.16 +/- 0.20 mg/L, respectively (P < 0.001). All patients with TINU syndrome showed a simultaneous decrease in serum KL-6 and urinary beta(2)-microglobulin levels after the beginning of treatment. Strong immunoreactivity for KL-6 was observed in renal distal tubules in biopsy tissue of patients with TINU syndrome. CONCLUSION We show a significant increase in serum KL-6 levels in patients with TINU syndrome, whereas levels were normal in patients with other causes of uveitis without nephritis. Renal distal tubules stained strongly with anti-KL-6 antibody, suggesting that high KL-6 levels may reflect the renal lesion of TINU syndrome. Serum KL-6 may be a potential laboratory parameter for the diagnosis and follow-up of patients with TINU syndrome that could complement urinary beta(2)-microglobulin measurements.
