Objective:To explore the clinical characteristics and genetic variants of two children with 3-hydroxy-3-methylglutaryl-coenzyme A lyase deficiency (HMGCLD).Methods:Two children with HMGCLD diagnosed at Henan Provincial Children′s Hospital respectively in December 2019 and June 2022 were selected as the study subjects. Clinical data and results of laboratory testing were analyzed retrospectively.Results:Both children had manifested with repeated convulsions, severe hypoglycemia, metabolic acidosis and liver dysfunction. Blood amino acids and acylcarnitine analysis showed increased 3-hydroxy-isovalyl carnitine (C5OH) and 3-hydroxy-isovalyl carnitine/capryloyl carnitine ratio (C5OH/C8), and urinary organic acid analysis showed increased 3-hydroxyl-3-methyl glutaric acid, 3-methyl glutaric acid, 3-methyl glutacoic acid, 3-hydroxyisoglycine and 3-methylprotarylglycine. Child 1 was found to harbor homozygous c. 722C>T variants of the HMGCL gene, which was rated as uncertain significance(PM2_Supporting+ PP3). Child 2 was found to harbor homozygous c. 121C>T variants of the HMGCL gene, which was rated as pathogenic(PVS1+ PM2_Supporting+ PP4). Conclusion:Acute episode of HMGCLD is usually characterized by metabolic disorders such as hypoglycemia and metabolic acidosis, and elevated organic acids in urine may can facilitate the differential diagnosis, though definite diagnosis will rely on genetic testing.

Objective:To explore the clinical features and genetic variants in three children suspected for β-ketothiolase deficiency (BKTD).Methods:Clinical manifestations, laboratory examination and genetic testing of three children suspected for BKTD at Henan Children′s Hospital between January 2018 and October 2022 were collected, and their clinical and genetic variants were retrospectively analyzed.Results:The children were all males with a age from 7 to 11 months. Their clinical manifestations have included poor spirit, shortness of breath, vomiting, convulsions after traumatic stress and/or infection. All of them had severe metabolic acidosis, elevated ketone bodies in blood and urine, hypoglycemia, with increased isoprenyl-carnitine and 3-hydroxyisovalyl-carnitine in the blood, and 2-methyl-3-hydroxybutyrate and methylprotaroyl glycine in the urine. All of them were found to harbor compound heterozygous variants of the ACAT1 gene, including c. 1183G>T and a large fragment deletion (11q22.3-11q23.1) in child 1, c. 121-3C>G and c. 826+ 5_826+ 9delGTGTT in child 2, and c. 928G>C and c. 1142T>C in child 3. The variants harbored by children 2 and 3 were known to be pathogenic or likely pathogenic. The heterozygous c. 1183G>T variant in child 1 was unreported previously and rated as a variant of unknown significance (PM2_Supporting+ PP3+ PP4) based on guidelines from the American College of Medical Genetics and Genomics. The large segment deletion in 11q22.3-11q23.1 has not been included in the DGV Database and was rated as a pathogenic copy number variation. Conclusion:The variants of the ACAT1 gene probably underlay the pathogenesis of BKTD in these three children.

Objective:To explore the efficacy and safety of sirolimus in the treatment of diazoxide unresponsive congenital hyperinsulinism(CHI) and summarize the single-center experience.Methods:A retrospective analysis was conducted on the clinical data of 5 cases of CHI treated with sirolimus after ineffective treatment with diazoxide, admitted to the Children′s Hospital Affiliated to Zhengzhou University from January 2017 to December 2022. The efficacy and safety of sirolimus in the treatment of CHI were evaluated.Results:The study included 5 patients, 3 males and 2 females. The age of onset ranged from 1 to 90 days. Initial symptoms included poor mental state(2/5) and convulsions(3/5). Blood glucose levels were 1.1 to 2.3 mmol/L, and insulin levels ranged from 13.52 to 70.53 μIU/mL. Two cases were classified as diffuse type, and the histological type of 3 cases was unknown. Genetic testing confirmed the diagnosis, with whole-exome sequencing revealing an unreported novel mutation in 1 case(ABCC8 exon 25_28del). Of the five patients, three patients were treated with sirolimus after diazoxide and octreotide failed, one patient was treated after unresponsive diazoxide, and the other one was treated after diazoxide, octreotide, and even near-total pancreatectomy failed. The onset age of sirolimus therapy ranged from 1 to 20 months. The maximum dosage of sirolimus was 1.2-3.2 mg·m -2·d -1, and the duration of medication ranged from 2 to 12 months. One patient was fully responsive to sirolimus, and the other four patients were partially responsive. All patients achieved euglycemia with sirolimus alone or in combination with standard CHI treatment. During follow-up, non-infectious diarrhea, elevated carcinoembryonic antigen, elevated triglycerides, and elevated liver enzymes were observed. Conclusion:This study indicates that sirolimus has a certain degree of efficacy in CHI patients for whom diazoxide treatment is ineffective. However, the long-term efficacy and safety warrant further multicenter trials.
