Epidemiological characteristics and influencing factors of adenovirus-associated acute conjunctivitis in Shenzhen，2014‒2022 / 上海预防医学

ObjectiveTo investigate the epidemic characteristics and influencing factors of acute conjunctivitis caused by human adenovirus（HAdv）in Yantian District of Shenzhen City， Guangdong Province from 2014 to 2022， and to provide evidence for formulating effective prevention and control measures. MethodsDescriptive epidemiology was used to analyze the epidemiological characteristics of acute hemorrhagic conjunctivitis （AHC） cases reported from the Chinese disease prevention and control information system. Etiological characteristics of laboratory-confirmed cases were analyzed， and a case-control study method of test-negative design （TND） was conducted as well. According to the result of HAdv detection， analysis was used to identify the influencing factors of morbidity. ResultsA total of 1 005 AHC cases were reported in Yantian District， Shenzhen City from 2014 to 2022， with an average annual incidence rate of 49.49/105. The incidence rate ranged from 4.67/105 to 117.28/105. The peak incidence occurred from July to October each year， with a male-to-female ratio of 1.42∶1. The median （P25，P75） age of onset was 29（12，40） years. A total of 716 eye swabs were collected for etiological detection from 2014 to 2022. HAdv positive detection rate was 36.45% （263/716）， Cox 24v positive detection rate was 0.28% （2/716）， while EV70 was not detected. The longest viral shedding time in eye swabs was 10 days， with a median of 2 days. The highest HAdv positive detection rate （47.47%） was observed when the sampling-to-onset interval was 4‒5 days， and the difference was statistically significant （P<0.05）， with a trend of first increasing and then decreasing. Multivariate logistic regressing analysis showed that aged 18‒ years， and average temperature higher than 24.90 ℃ 3 days before onset （P<0.05） were the risk factors for acute HAdv conjunctivitis. ConclusionAHC in Yantian District， Shenzhen City showed a low level of prevalence from 2014 to 2022， with HAdv being the predominant pathogen. The peak period of viral shedding occurred on the 4th to 5th day after symptom onset， suggesting the importance of adherence to strict home isolation for infected persons. Aged18‒ years and average temperature increased 3 days before onset are associated with an increased risk of adenoviral conjunctivitis. It is recommended to strengthen personal protection and keep doing a good job of AHC surveillance and early warning， so as to timely prevent the outbreaks of AHC.

The main clinical manifestations included growth restriction and developmental delay after birth, accompanied by craniofacial deformities. At 7 months old, he was diagnosed as epilepsy due to convulsive limbs. At present, he is 2 years old, still has recurrent convulsions, can not raise his head, sit alone, crawl and talk, with hypotonia. Repeated cranial magnetic resonance imaging showed agenesis of the corpus callosum. The child′s parents had normal phenotypes. His copy number variation sequencing results showed partial overlap of chromosome 5p15.1-5p15.33 (chr5:1934522-18905656), which was determined as pathogenic copy number variation according to copy number variations evaluation criteria, and no abnormality was detected in his parents. According to the retrieval strategy set in this study, 10 literatures (all in English, reporting 17 cases) were retrieved, and a total of 22 5p duplication syndrome patients (including this case and 4 cases included in databases) were included. Seventeen of the 22 patients were younger than 14 years old with a onset age of 7 (0, 18) years, and the male to female ratio was about 1.1∶1. Among the 22 patients, craniofacial malformation was found in 19 patients, developmental disorder in 18, bone/muscle dysplasia in 15, autism in 11, attention deficit hyperactivity disorder in 9, mental retardation in 8, obesity in 5, epilepsy in 5, congenital heart dysplasia in 2, hypotonia in 4, strabismus/hyperopia in 2, and corpus callosum dysplasia, endocrine dysfunction, inguinal hernia as well as umbilical hernia in 1, respectively. There were 19 cases of multiple malformation and 3 cases of single malformation.Conclusions:5p15.1-5p15.33 duplication may be the genetic cause of this child. Facial malformation, developmental delay, skeletal/muscular dysplasia, intellectual disability, autism spectrum disorder and attention deficit hyperactivity disorder are the main clinical phenotypes of 5p copy number duplication. Corpus callosum dysplasia may be an extended phenotype of chromosome duplication at this location.

Analysis of a Chinese pedigree affected with rare heart diseases due to variants of TNNI3 and TAZ genes / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic basis for a Chinese pedigree affected with rare type heart disease.@*METHODS@#A pedigree identified at Shenzhen Maternity and Child Health Care Hospital Affiliated to Southern Medical University on July 9, 2021 was selected as the study subject. Clinical data were collected. Trio-whole exome sequencing (WES) was carried out for the proband and his parents. Candidate variants were validated by Sanger sequencing of his family members and bioinformatic analysis.@*RESULTS@#The proband, a 5-month-old male, was found to have Barth syndrome (dilated myocardiopathy and left ventricular non-compaction). Trio-WES revealed that he has harbored a hemizygous c.542G>A (p.G181A) variant of the TAZ gene, which was inherited from his mother. In addition, his mother, aunt and maternal grandmother were also found to harbor a c.557G>A (p.R186Q) variant of the TNNI3 gene. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c.542G>A (p.G181A) variant of the TAZ gene was classified as likely pathogenic (PS2_Strong+PM2_Supporting+PP3), whilst the c.557G>A (p.R186Q) variant of the TNNI3 gene was classified as pathogenic (PP1_Strong+PS4_Strong+PP3+PP4+PM2_Supporting).@*CONCLUSION@#The c.542G>A (p.G181A) variant of the TAZ gene probably underlay the Barth syndrome in the proband, and the c.557G>A (p.R186Q) variant of the TNNI3 gene may be responsible for the hypertrophic cardiomyopathy in his mother, aunt and maternal grandmother. Above finding has expanded the mutational spectrum of the TAZ gene and facilitated the diagnosis of this pedigree.

Erythroferrone is a newly discovered and important factor regulating iron homeostasis and mainly produced by erythroblasts. Erythroferrone responds to the increase of erythropoietin and regulates plasma iron level, along with the absorption and utilization of iron via hepcidin, which plays an important role in the pathophysiology of iron metabolism-related diseases. Erythropoietin deficiency and iron metabolism disturbance are prominent features of renal anemia complicated with chronic kidney disease. Accordingly, erythroferrone is corresponding to the pathogenesis, treatment and prognosis of renal anemia. The in-depth study contributes to the further understanding of the mechanism related to iron metabolism disorder, and erythroferrone is also expected to be used as a valuable biomarker in the detection of renal anemia and the evaluation of therapeutic response. The article systematically reviews the physiological function of erythroferrone and its research progress in iron metabolism and renal anemia.
