Background: Uveitis and acute renal failure can be seen in various immune-mediated systemic diseases. Here we present a case of a young man with a rare inflammatory oculorenal syndrome.
Case Report: A man in his thirties was admitted with a constellation of fatigue, flank pain, weight loss and bilateral acute anterior uveitis. Laboratory tests showed anaemia, leukocytosis with eosinophilia, as well as elevated creatinine and C-reactive protein, and urine analyses demonstrated mild proteinuria. Work-up excluded sarcoidosis, Sjögren's syndrome, systemic lupus erythematosus, ANCA-associated vasculitides, Behçet disease, spondyloarthritis and infection. Renal biopsy showed severe tubulointerstitial nephritis.
Interpretation: Following exclusion of the abovementioned disorders, a diagnosis of tubulointerstitial nephritis and uveitis (TINU) syndrome was made. TINU syndrome is a rare inflammatory disorder which can be diagnosed in patients presenting with uveitis and tubulointerstitial nephritis after exclusion of other causes of similar oculorenal involvement.

The renal tubule and collecting duct express a large number of proteins, all having putative immunoreactive motives. Therefore, all can be the target of pathogenic autoantibodies. However, autoimmune tubulopathies seem to be rare and we hypothesize that they are underdiagnosed.

Protothecosis is an infectious disease caused by unicellular algae of the genus Prototheca, which are mainly known for causing mastitis in farm animals. However, there are reports of protothecosis in humans and other animals, such as dogs and cats, which develop cutaneous lesions or systemic lesions. Dogs with the systemic form generally develop bloody diarrhoea and blindness and neurological signs may also occur.

Article Synopsis
- * An 18-year-old female with a history of recurring oral ulcers developed additional symptoms over ten years, leading to diagnoses of both BD and IgA nephropathy after biopsies.
- * The case highlights the rarity of co-occurrence between BD and IgAN in China, emphasizing the need for regular monitoring of kidney function in BD patients to catch potential issues early on.

Purpose: To report two patients who presented with scleritis associated with tubulointerstitial nephritis and uveitis syndrome (TINU).
Results: A 13-year-old male initially presenting with unilateral panuveitis with scleritis in the fellow eye was ultimately diagnosed with TINU. A 33-year-old male previously diagnosed with TINU presented with recurrent bilateral episcleritis as well as bilateral scleritis eight years after his first episode of bilateral anterior uveitis.
