Acute gestational pyelonephritis: the impact on colloid osmotic pressure, plasma fibronectin, and arterial oxygen saturation.
Acute gestational pyelonephritis infrequently leads to nonhydrostatic permeability pulmonary edema known clinically as acute respiratory distress syndrome (ARDS). In this form of ARDS, sepsis is considered the primary cause of pulmonary dysfunction. Decreases in colloid osmotic pressure, plasma fibronectin, and arterial oxygen saturation are associated with a worsening prognosis in septic conditions. We sought to investigate the changes in these parameters with acute gestational pyelonephritis to gain insight into the factors that may place the patient at risk for sepsis-related morbidity. Colloid osmotic pressure, plasma fibronectin, and arterial oxygen saturation via pulse oximetry were prospectively measured during the inpatient treatment of 17 pregnant patients with acute gestational pyelonephritis. All three parameters achieved their nadir within 24 hours of hospitalization and the initiation of therapy. Although no patient developed significant pulmonary dysfunction, we believe that patient susceptibility for pulmonary edema and general morbidity could be maximal in the first 24 hours after therapy. Future studies using a larger number of patients may identify one or more of these laboratory parameters as helpful in identifying gravid patients who are at risk of developing gestational ARDS.
