Acute post‐streptococcal glomerulonephritis in Central Australia

Abstract Objective To determine the incidence, clinical presentation and progress of acute post‐streptococcal glomerulonephritis in Central Australia. Design Retrospective observational analysis. Setting Paediatric inpatient admission at Alice Springs Hospital. Participants Patients admitted to Alice Springs Hospital under 14 years of age meeting diagnostic criteria for acute post‐streptococcal glomerulonephritis between January 2010 and December 2014. Main Outcome Measures Incidence of acute post‐streptococcal glomerulonephritis in central Australia. Biochemical abnormalities associated with acute post‐streptococcal glomerulonephritis. Co‐occuring conditions. Results Sixty‐nine out of the 174 cases reviewed were identified as having either acute post‐streptococcal glomerulonephritis (63) or probable acute post‐streptococcal glomerulonephritis (6). We calculate the incidence of APSGN admission to be higher than previously reported and the highest reported incidence globally in children. Clinical evidence of skin infection was frequently documented. Co‐occurring infections were common, including scabies/head lice, urinary tract infection and pneumonia. Fifty‐three patients showed biochemical evidence of acute kidney injury. Conclusions Aboriginal children in Central Australia have the highest incidence of acute post‐streptococcal glomerulonephritis reported worldwide. Urgent action is required to improve housing and reduce overcrowding in Central Australian towns and communities to reduce the burden of disease of skin infection and Group A Streptococcus related diseases. Without effective change in living conditions, it is unlikely that there will be a significant change in the morbidity related to these conditions.
