Abstract

fetched live from OpenAlex

Granulomatosis with polyangiitis (GPA) is a rare disorder characterised by inflammation of small-sized and medium-sized blood vessels that result in damage to various organ systems, but it most commonly affects the respiratory tract and kidneys. It is one of the few entities that can present with ocular inflammation as well as renal impairment at the same time. We describe a case of a 38-year-old man with conjunctivitis, episcleritis, anterior uveitis as a first manifestation of GPA. His presentation with red eye and anterior uveitis prompted further workup, which revealed acute renal failure (creatinine 442 mmol/L), elevated inflammatory markers (erythrocyte sedimentation rate of 85 mmol/hour and C reactive protein of 72 mg/L), and a c-antineutrophil cytoplasmic antibody titre >8. An urgent renal biopsy was performed demonstrating necrotising crescentic glomerulonephritis, which led to the final diagnosis of GPA. Treatment induction with intravenous methylprednisolone and plasmapheresis followed by an oral prednisone taper and intravenous rituximab infusions leading to resolution of all symptoms and normalisation of kidney function. This report highlights conditions that can present with both ocular inflammation and renal dysfunction with a focus on GPA and its ocular manifestations.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
