Liver abscesses occur in up to one-third of patients with chronic granulomatous disease (CGD). Surgery has traditionally been considered the cornerstone of management. Emerging reports in older children and adults, however, have demonstrated successful treatment of CGD-related liver abscesses with corticosteroids and antibiotics alone. We describe the safe and effective use of corticosteroids and antibiotics for CGD-related liver abscesses in an infant with X-linked CGD who had high surgical risk for hepatic resection. Medical management was started at 11 months of age and the abscesses resolved without requiring any subsequent invasive surgical procedures. This case report highlights that corticosteroids and antibiotics may be considered in the management of CGD-related liver abscesses in the infant age group, especially when surgical management is not an option.
1. Introduction Liver abscesses occur in up to 35% of patients with chronic granulomatous disease (CGD), with Staphylococcus aureus being the most frequently cultured pathogen [1,2]. The management of liver abscesses in CGD patients is not well-defined, but surgery has been a cornerstone of therapy [3,4]. A small number of reports in older children and young adults have described successful treatment of CGD-related liver abscesses with corticosteroids [2,5–7], with a more recent case series describing this approach as a “changing paradigm of management of liver abscesses” in CGD [8]. We report a case of an infant with X-linked CGD and a liver abscess successfully treated with corticosteroid and targeted antibiotic therapy without surgical resection. Written informed consent was obtained from the patient's family for this case report. 1.1. Case report A term male infant with a longstanding history of fevers and lymphadenitis developed abdominal distension and right upper quadrant
pain at 10 months of age. Abdominal ultrasound demonstrated a 5.0 × 1.8 × 2.0 cm hepatic subcapsular complex collection. He was empirically started on parenteral piperacillin-tazobactam and ciprofloxacin. CT abdomen (Fig. 1) confirmed a large subcapsular abscess (4.5 × 2.1 × 3.9 cm) on the right side of the liver anteriorly along segment V with extension into the hepatic parenchyma (Fig. 1A), as well as a second ill-defined lesion (0.8 × 0.6 × 0.9 cm) on the left side of the liver anteriorly along the falciform ligament (Fig. 1B). The subcapsular abscess was drained via image-guided therapy the following day, yielding 8 mL of pus, which grew methicillin-sensitive Staphylococcus aureus (MSSA). Piperacillin-tazobactam was changed to parenteral cloxacillin (50 mg/kg every 6 h) and ciprofloxacin was continued for one week while a percutaneous drain remained in situ. Neutrophil oxidative burst index was low on two occasions (9 and 1.1, with normal range 32–300). A clinical diagnosis of CGD was made, later confirmed to be due to a hemizygous nonsense mutation in the CYBB gene ((c.931C > T, p.Gln 311, Denver Genetic Laboratories)), which was classified as pathogenic. At 4 weeks of admission (11 months of age), the patient continued to have intermittent fever, abdominal pain, and elevated inflammatory

prophylactic itraconazole. Prophylactic trimethoprim-sulfamethoxazole was also initiated. Serial abdominal ultrasound imaging continued to be reassuring with gradually decreasing size of left hepatic lesions with increasing internal calcifications. The right subcapsular abscess did not re-accumulate and no new hepatic lesions occurred. Prednisolone wean started 6 weeks after initiation by approximately 20% weekly. IV cloxacillin was changed to oral cephalexin 150 mg/kg/day divided three times daily at just over 3 months of antibiotic therapy, and continued for an additional 4 months until abdominal imaging only showed small clusters of tiny calcifications. At 2 years of age, the patient underwent bone marrow transplantation for CGD. At over one year post-transplant, there was no evidence of recurrence of liver abscesses. His clinical course is summarized (Table 1).
markers (CRP 66.6 mg/L and ESR 53 mm/h) despite continuing IV cloxacillin. While the right subcapsular abscess had decreased in size post-drainage to 2.1 × 1.9 × 0.4 cm, the lesion in the left hepatic lobe had increased to 1.3 × 1.7 × 1.3 cm with a 2.8 × 1.9 × 2 cm area of surrounding hypoechoic halo. Surgical resection of the abscess was considered; however, based on the location of the lesions and the otherwise stable clinical status, the procedure was deemed to be high risk. Therefore, medical management was attempted with methylprednisolone intravenously (IV) (1 mg/kg/day), while continuing IV cloxacillin. His fevers abated following initiation of corticosteroids. Within one week, his inflammatory markers normalized and abdominal ultrasound demonstrated the right subcapsular abscess had decreased to 3 mm thickness and the left hepatic lobe lesion had decreased to 2.4 × 0.9 × 1.2 cm. Following 2 weeks of IV methylprednisolone, he was discharged home on oral prednisolone (1.5 mg/kg/day divided twice daily), IV cloxacillin, and itraconazole for fungal prophylaxis. Five days after discharge, the patient developed new fever. A CT abdomen showed the right subcapsular liver abscess had almost completely resolved (Fig. 1-2A). However, the left hepatic lesion increased to 1.4 × 1.7 × 2.7 cm (Fig. 1-2B); a biopsy showed only sterile fibrotic granulation tissue. Blood cultures remained negative and he was discharged home to continue oral prednisolone, IV cloxacillin and
2. Discussion We report a case description of an infant with CGD successfully treated for a liver abscess with antibiotic and corticosteroid therapy, thereby avoiding surgical resection. The management of liver abscesses in CGD patients has often included hepatic resection, due to disappointing results from only drainage of the abscess [4]. The risks of Fig. 1. Axial contrast enhanced CT images initially (1) and two months later (2). 1A. A heterogeneous sub-capsular liver lesion (thick white arrow) along segment V demonstrates a low attenuation region with peripheral rim enhancement concerning for an abscess with surrounding phlegmon. It appears to involve the underlying liver parenchyma and likely the adjacent abdominal wall. 1B. A smaller 0.8 × 0.6 × 0.9 cm hypoattenuating lesion (thin white arrow) is seen adjacent to the falciform ligament. 2A. The sub-capsular lesion resolved (thick white arrow) and attenuation changes are improved. 2B. The lesion increased in size (thin white arrow), measuring 1.4 × 1.7 × 2.7 cm.

surgery, however, are high with a surgical complication rate of up to 56% described in a case series of patients aged 2–31 years old [3]. The most common complications included persistence of the abscess, wound dehiscence, pancreatitis, and pneumonia [2,3]. In our patient, surgery was not an optimal option given the anatomical position and ill-defined lesions. Our case also highlights that increasing size of intrahepatic lesions is not necessarily an indication of failure of medical treatment. The patient's clinical status, inflammatory markers, and lesion biopsy were helpful to determine that the lesion was fibrotic granulation tissue rather than an active infection. A concern of an increased risk of infection with glucocorticoid use was mitigated by directed treatment against the initial proven pathogenic organism (MSSA) and the use of bacterial and fungal prophylaxis with antimicrobials. Case reports and case series have described successful treatment of CGD liver abscesses with corticosteroids [2,5–8]. Although the corticosteroid doses varied amongst the patients, the average starting dose was methylprednisolone 1 mg/kg for 2–3 weeks with an average taper of 3 months [2]. Only one case series has included any infant. Straughan et al. [8] reported a retrospective case series at the National Institutes of Health (Bethesda, Maryland) of 26 patients from 1980 to 2014 with CGD and liver abscesses in which 8 patients were treated with only corticosteroids and antibiotics. The median age at initiation of corticosteroids was 19 years (range 0.5–46) with the youngest being 6 months at corticosteroid initiation. Our patient differs from this series in that he had partially successful percutaneous interventional radiologic drainage followed by high dose corticosteroid management. Furthermore, we describe that our patient underwent successful hematopoietic stem cell transplantation after the medical management of his abscess. Our case report contributes to the collective experience of using corticosteroids and antibiotics in the management of CGD-related liver abscesses in the infant age group.

3. Conclusion In conclusion, this case report is to our knowledge the second report of safe and effective use of antibiotics and corticosteroids in the management of an infant with CGD and intrahepatic lesions who had a high surgical risk for hepatic resection. This case highlights the paradigm change away from open surgical procedures in the management of abscesses in patients with CGD. Corticosteroids plus antibiotics, in conjunction with close clinical and radiologic follow-up, may allow for resolution of liver abscesses without surgery in some infants.
