Actinomycosis-Induced Lung Abscess and Empyema After the Treatment of Idiopathic Focal Segmental Glomerulosclerosis

Abstract

In adults, focal segmental glomerulosclerosis occurs in approximately 35% of nephrotic syndrome cases. Proteinuria can be reduced using steroids or immunosuppressive drugs in patients with focal segmental glomerulosclerosis (FSGS) with proteinuria at the nephrotic level. However, depending on the corticosteroid treatment, immunosuppression develops and opportunistic infections are predisposed. Actinomycosis, one of the opportunistic infections, is a rare bacterial lung infection. Clinically, it has seen most frequently in the cervicofacial region by 50-60%, then in the abdominal region by 25% and in the thoracic region by 15%. In our case of FSGS diagnosed with renal biopsy, after the steroid use, empyema and bronchopleural fistula (BPF) were developed. In this study, we report a case of successful management of actinomycosis and complications after tube thoracostomy and decortication with antibiotherapy treatment.
