Factors Predicting Renal Outcomes in Hypertensive Emergencies With Severe Renal Impairment: A Single-Center Retrospective Study.

Background And Aims: Hypertensive emergencies, characterized by elevated blood pressure (BP) and multiple organ damage, have poor prognosis. Patients occasionally show gradual improvement in renal function with appropriate antihypertensive treatment despite renal impairment. However, reports analyzing factors predicting prognosis in patients with hypertensive emergencies and severe renal impairment are limited.

Anti-neutrophil Cytoplasmic Antibody-associated Vasculitis Superimposed on Post-streptococcal Acute Glomerulonephritis.

A 44-year-old woman was admitted due to gross hematuria and progressive renal dysfunction. Poststreptococcal acute glomerulonephritis (PSAGN) was suspected due to her elevated anti-streptolysin O and anti-streptokinase titers and hypocomplementemia. A renal biopsy showed crescent formation and endocapillary hypercellularity with neutrophil infiltrate.
