Pulmonary tularemia with antineutrophil-cytoplasmic-antibody-negative pauci-immune crescentic glomerulonephritis causing acute kidney injury: a case report and review of the literature

Pulmonary tularemia complicated by acute kidney injury is an uncommon clinical constellation. Biopsy-proven pauci-immune crescentic glomerulonephritis with antineutrophil-cytoplasmic-antibody-negativity in this setting appears to be very rare. Careful differential diagnosis, early recognition of tularemia, and timely initiation of effective antibiotic therapy are critical to achieving favorable outcomes.
