Real-life effects, complications, and outcomes in 39 critically ill neonates receiving continuous kidney replacement therapy.

BACKGROUND: Continuous kidney replacement therapy (CKRT) has been expanded from simple kidney replacement therapy to the field of critical illness in children. However, CKRT is rarely used in critically ill neonates in the neonatal intensive care unit (NICU). This study aimed to describe patients' clinical characteristics at admission and CKRT initiation, CKRT effects, short-term outcomes, and predictors of death in critically ill neonates. METHODS: A 7-year single-center retrospective study in a tertiary NICU. RESULTS: Thirty-nine critically ill neonates received CKRT between May 2015 and April 2022 with a mortality rate of 35.9%. The most common primary diagnosis was neonatal sepsis in 15 cases (38.5%). Continuous veno-venous hemodiafiltration and continuous veno-venous hemofiltration were applied in 43.6% and 56.4% of neonates, respectively. The duration of CKRT was 44 (18, 72) h. Thirty-one patients (79.5%) had complications due to CKRT-related adverse events, and the most common complication was thrombocytopenia. Approximately 12 h after the CKRT initiation, urine volume, mean arterial pressure, and pH were increased, and serum creatinine, blood urea nitrogen, and blood lactate were decreased. In the multivariate logistic regression analysis, neonatal critical illness score [odds ratio 0.886 (0.786 ~ 0.998), P = 0.046] was an independent risk factor for death in critically ill neonates who received CKRT. CONCLUSIONS: CKRT can be an effective and feasible technique in critically ill neonates, but the overall mortality and CKRT-related complications are relatively high. Furthermore, the probability of death is greater among neonates with greater severity of illness at CKRT initiation.

Detection of a novel SETBP1 variant in a Chinese neonate with Schinzel-Giedion syndrome.

Schinzel-Giedion syndrome (SGS) is a multiple malformation syndrome characterized by typical facial features, severe neurodevelopmental delay, and multiple congenital abnormalities. SGS is associated with de novo pathogenic variants in the SETBP1 gene. In specific, SETBP1 variants in over 50 patients with classical or non-classical SGS were clustered within exon 4. A male Chinese neonate with dysmorphic facial features, nervous system disorders, and organ malformations at birth was examined in this study and long-term followed-up. Whole-exome sequencing was performed to identify any underlying pathogenic variants in the proband. Additionally, we reviewed the literature that documents the main clinical features and underlying variants of all patients genetically diagnosed with SGS. The neonate had a characteristic midface retraction, abnormal electroencephalogram waveforms, and genital abnormalities. The patient did not initially develop hydronephrosis or undergo a comprehensive skeletal assessment. Six months after birth, the patient had an epileptic seizure and experienced persistent neurodevelopmental delay with auditory and visual abnormalities. Color Doppler ultrasonography at 18 months revealed hydronephrosis and bilateral widening of the lateral ventricles. The patient died suddenly 20.5 months after birth. Whole-exome sequencing revealed a heterozygous de novo variant (c.2605A > G:p.S869G) in exon 4 degradation sequence in SETBP1. The reported de novo heterozygous variant in SETBP1 (c.2605A > G:p.S869G) broadens the knowledge of the scientific community's on the possible SGS genetic alterations. To the best of our knowledge, this is the first report of SETBP1 variant (c.2605A > G:p.S869G) in SGS. The clinical manifestations of neonatal SGS are atypical, and genetic testing is crucial for diagnosis. Long-term follow-up should be conducted after diagnosis to optimize the therapeutic interventions.

Giant spider angioma following cirrhosis in HIV-infected individuals.

Spider angioma refers to a type of telangiectasis that presents slightly beneath the skin surface on the face, neck, arms or upper trunk, often manifesting with a central red spot and reddish extensions that radiate outwards like a spider's web. The cutaneous spider angioma may be benign but it often indicates abnormal liver function, especially in patients with chronic cirrhosis. The spider angioma is irreversible and rarely occurred diffusely over the body or with giant sizes. Here, we report two rare multiple and giant spider angioma cases in patients with HIV/AIDS who developed chronic cirrhosis. In addition, we comprehensively reviewed related literatures and evaluated the existing possible mechanisms of spider angioma.
