A 35-year-old Philipino female presented to our unit with advanced chronic kidney disease, secondary to medullary cystic kidney disease, which was diagnosed many years earlier in the Philipines. She had no significant heart disease. One year later, she was approaching end-stage kidney disease and a Tenckhoff catheter was inserted. Training for PD began four weeks later, using standard dextrose-based solutions.\nShe presented after four days of PD training with dyspnoea. She was otherwise well and was afebrile. Blood tests and ECG were unchanged. She had clinical evidence of a large, rightsided pleural effusion. This was confirmed on a chest radiograph (). A diagnostic aspirate was performed and yielded serous fluid. The pleural fluid biochemistry was consistent with a transudative process (). The high-pleural-fluid-serum-glucose ratio confirmed the clinical suspicion of a pleuroperitoneal leak.\nThe pleural effusion resolved over a number of days with conservative management and the maintenance of a dry peritoneal cavity. A follow-up chest radiograph was normal (). In accordance with patient preference, PD was discontinued. Haemodialysis (HD) access was established and HD is ongoing one year later.
A 13-year-old Indonesian boy who experienced successful living-related renal transplantation (LRRT) in 2017 (his 50-year-old father was his kidney donor) has been living with normal graft function. He underwent hemodialysis (HD) in 2014 after being diagnosed with end-stage renal disease (ESRD) secondary to bilateral renal hypoplasia. He was prepared for LRRT in March 2015; however, two months prior to the procedure he was infected with the hepatitis A virus (HAV). The HAV infection subsequently resolved, and LRRT preparations proceeded. Unfortunately, seven days prior to the scheduled LRRT procedure, there was a sudden significant rise in alanine transaminase (ALT) and aspartate aminotransferase (AST) levels, resulting in cancellation of the procedure. The rise in ALT and AST levels was later revealed to be caused by HCV seroconversion (). The patient was always hemodialyzed with a single-use dialyzer, and there was no history of blood transfusions or family history of viral hepatitis; however, there was an HCV outbreak in our pediatric dialysis unit in 2015.\nIn April 2015, his liver function markers rose (AST 498 U/L, ALT 816 U/L, Gamma-Glutamyltransferase (GGT) 170 U/L) and he was subsequently diagnosed with HCV infection (viral load 3.75 × 105 IU/mL, 5.57 log IU/mL of serum HCV RNA) (). HCV RNA genotype testing was conducted using hybridization probe (The Versant HCV Genotype 2.0 Assay (LiPA), Siemens), which revealed HCV genotype 1a. A 7.3-kPa liver stiffness was observed with transient elastography (fibroscan), which was categorized as F1-F2 (mild–moderate liver fibrosis) ().\nHe received interferon-based therapy with ribavirin post-HD once a week since September 2015. Six months after treatment initiation, the HCV was undetected and his liver function normalized. However, 10 months after treatment initiation, he had HCV virological breakthrough, suggested by HCV RNA of 1.28 × 104 IU/mL (4.11 Log IU/mL), leading to cessation of interferon therapy.\nPlans for LRRT were continued and HCV treatment was set up to be given a year post LRRT when stable renal graft function was achieved. In September 2017, LRRT was conducted. One year post-LRRT, graft function was normal; thus, treatment with DAAs for chronic HCV infection was commenced. Owing to a lack of evidence regarding treatment safety with DAAs in pediatrics, we arranged a thorough discussion with the Hospital Ethics Committee to obtain parental consent. In December 2018, he began receiving sofosbuvir/daclatasvir for 12 weeks. Evaluation immediately after (March 2019), at 12 weeks (June 2019), and at 24 weeks (October 2019) following treatment cessation showed no HCV recurrence (). Adverse effects, such as mild fever, fatigue, musculoskeletal pain, decreased appetite, itching and nasal congestion, were not found during treatment with DAAs.
