Abstract
PURPOSE The purpose of this study was to systematically review the research literature with regards to treatments and intervention methods for hereditary hearing loss. Our goal was to provide reference guidelines for the rational use of medication and gene-targeted therapy for patients with hereditary hearing loss and discuss the future development of research in this area. METHOD We searched two core databases, PubMed and Web of Science, for relevant literature relating to potential treatments and interventional methods for hereditary hearing loss. Then, we used Microsoft Excel to perform basic statistical analysis of the data, the R language to perform bibliometric analyses, and VOSviewer and CiteSpace to visualize data. In addition, we clustered and descriptively analyzed the data and identified the relative importance of each approach with regard to precise patient outcomes. RESULTS In this study, we followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standardized screening process and identified a total of 103 research articles. The average annual growth rate of publications in this area was 12.73%. The country with the highest number of publications and citations was the United States; 80 of these publications (associated with 76.92% of funding) were supported by grants from 16 countries. Potential treatments and interventions were clustered according to the stage of research and showed that 8.74% remain in the research design stage, 59.22% are in the clinical validation stage, and 32.04% are being applied in the clinic. The main research focus in this field is cochlear implants and gene therapy. CONCLUSIONS Hereditary hearing loss is in a critical period of transition from preventive to therapeutic research. Gene-targeted interventions represent one of the most promising and effective treatments. SUPPLEMENTAL MATERIAL https://doi.org/10.23641/asha.24309193.

Abstract
PURPOSE If before cochlear implantation it was possible to assay biomarkers of neuroplasticity, we might be able to identify those children with congenital deafness who, later on, were at risk of poor speech and language rehabilitation outcomes. METHODS A group of 40 children aged up to 2 years with DFNB1-related congenital deafness was observed in this prospective cohort study over three follow-up intervals (0, 8, and 18 months) after cochlear implant (CI) activation. Children were assessed for auditory development using the LittlEARS Questionnaire (LEAQ) score, and at the same time, measurements were made of matrix metalloproteinase-9 (MMP-9) plasma levels. RESULTS There were significant negative correlations between plasma levels of MMP-9 at 8-month follow-up and LEAQ score at cochlear implantation (p = 0.04) and LEAQ score at 18-month follow-up (p = 0.02) and between MMP-9 plasma levels at 18-month follow-up and LEAQ score at cochlear implantation (p = 0.04). As already reported, we confirmed a significant negative correlation between MMP-9 plasma level at cochlear implantation and LEAQ score at 18-month follow-up (p = 0.005). Based on this latter correlation, two clusters of good and poor CI performers could be isolated. CONCLUSIONS The study shows that children born deaf who have an MMP-9 plasma level of less than 150 ng/ml at cochlear implantation have a good chance of attaining a high LEAQ score after 18 months of speech and language rehabilitation. This indicates that MMP-9 plasma level at cochlear implantation is a good prognostic marker for CI outcome.

Otolaryngol Head Neck Surg 2023; 169:210-220. [PMID: 36939587 DOI: 10.1002/ohn.284] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 12/20/2022] [Accepted: 01/16/2023] [Indexed: 02/10/2023]
Abstract
OBJECTIVE To systematically review the literature to determine auditory outcomes of cochlear implantation in children ≤12 months old. DATA SOURCE PubMed, EMBASE, Medline, CINAHL, Cochrane, Scopus, and Web of Science databases were searched from inception to 9/1/2021 using PRISMA guidelines. REVIEW METHODS Studies analyzing auditory outcomes after cochlear implantation (CI) in children ≤12 months of age were included. Non-English studies and case reports were excluded. Outcome measures included functional and objective auditory results. Two independent reviewers evaluated each abstract and article. Heterogeneity and bias across studies were evaluated. RESULTS Of 305 articles identified, 17 met inclusion criteria. There were 642 children ages 2 to 12 months at CI. The most common etiologies of hearing loss were congenital CMV, meningitis, idiopathic hearing loss, and GJB2 mutations and other genetic causes. All studies concluded that early CI was safe. Overall, outcomes improved following early CI: IT-MAIS (9 studies), LittlEARS (4 studies), PTA (3 studies), CAP (3 studies), GASP (3 studies), and LNT (3 studies). Nine studies compared outcomes to an older implantation group (>12 months); of these (n = 450 early CI, n = 1189 late CI), 8 studies showed earlier CI achieved comparable or better auditory outcomes than later implantation, whereas 1 study (n = 120) concluded no differences in speech perception improvement. CONCLUSION Auditory outcomes were overall improved in children ≤12 months old undergoing CI. Studies that compared early to late CI demonstrated similar or better auditory outcomes in early implantation group. Given the comparable safety profile and critical time period of speech and language acquisition, earlier CI should be considered for infants with hearing loss.

Abstract
Congenitally deaf children who undergo cochlear implantation before 1 year of age develop their auditory skills faster than children who are implanted later. In this longitudinal study, a cohort of 59 implanted children were divided into two subgroups according to their ages at implantation-below or above 1 year old-and the plasma levels of matrix metalloproteinase-9 (MMP-9), brain-derived neurotrophic factor (BDNF), and pro-BDNF were measured at 0, 8, and 18 months after cochlear implant activation, while auditory development was simultaneously evaluated using the LittlEARs Questionnaire (LEAQ). A control group consisted of 49 age-matched healthy children. We identified statistically higher BDNF levels at 0 months and at the 18-month follow-ups in the younger subgroup compared to the older one and lower LEAQ scores at 0 months in the younger subgroup. Between the subgroups, there were significant differences in the changes in BDNF levels from 0 to 8 months and in LEAQ scores from 0 to 18 months. The MMP-9 levels significantly decreased from 0 to 18 months and from 0 to 8 months in both subgroups and from 8 to 18 months only in the older one. For all measured protein concentrations, significant differences were identified between the older study subgroup and the age-matched control group.

Searching for the Molecular Basis of Partial Deafness. Int J Mol Sci 2022; 23:ijms23116029.

Abstract
Hearing is an important human sense for communicating and connecting with others. Partial deafness (PD) is a common hearing problem, in which there is a down-sloping audiogram. In this study, we apply a practical system for classifying PD patients, used for treatment purposes, to distinguish two groups of patients: one with almost normal hearing thresholds at low frequencies (PDT-EC, n = 20), and a second group with poorer thresholds at those same low frequencies (PDT-EAS, n = 20). After performing comprehensive genetic testing with a panel of 237 genes, we found that genetic factors can explain a significant proportion of both PDT-EC and PDT-EAS hearing losses, accounting, respectively, for approx. one-fifth and one-half of all the cases in our cohort. Most of the causative variants were located in dominant and recessive genes previously linked to PD, but more than half of the variants were novel. Among the contributors to PDT-EC we identified OSBPL2 and SYNE4, two relatively new hereditary hearing loss genes with a low publication profile. Our study revealed that, for all PD patients, a postlingual hearing loss more severe in the low-frequency range is associated with a higher detection rate of causative variants. Isolating a genetic cause of PD is important in terms of prognosis, therapeutic effectiveness, and risk of recurrence.

Prospective cohort study reveals MMP-9, a neuroplasticity regulator, as a prediction marker of cochlear implantation outcome in prelingual deafness treatment. Mol Neurobiol 2022; 59:2190-2203. [PMID: 35061219 PMCID: PMC9262127 DOI: 10.1007/s12035-022-02732-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Accepted: 01/04/2022] [Indexed: 11/11/2022]
Abstract
Because of vast variability of cochlear implantation outcomes in
prelingual deafness treatment, identification of good and poor performers remains a
challenging task. To address this issue, we investigated genetic variants of matrix
metalloproteinase 9 (MMP9) and brain-derived
neurotrophic factor (BDNF) and plasma levels of
MMP-9, BDNF, and pro-BDNF that have all been implicated in neuroplasticity after
sensory deprivation in the auditory pathway. We recruited a cohort of prelingually
deaf children, all implanted before the age of 2, and carried out a prospective
observation (N = 61). Next, we analyzed the
association between (i) functional MMP9 (rs20544,
rs3918242, rs2234681) and BDNF (rs6265) gene
variants (and their respective protein levels) and (ii) the child’s auditory
development as measured with the LittlEARS Questionnaire (LEAQ) before cochlear
implant (CI) activation and at 8 and 18 months post-CI activation. Statistical
analyses revealed that the plasma level of MMP-9 measured at implantation in
prelingually deaf children was significantly correlated with the LEAQ score
18 months after CI activation. In the subgroup of DFNB1-related deafness (N = 40), rs3918242 of MMP9 was significantly associated with LEAQ score at 18 months after
CI activation; also, according to a multiple regression model, the ratio of plasma
levels of pro-BDNF/BDNF measured at implantation was a significant predictor of
overall LEAQ score at follow-up. In the subgroup with DFNB1-related deafness, who
had CI activation after 1 year old (N = 22), a
multiple regression model showed that rs3918242 of MMP9 was a significant predictor of overall LEAQ score at
follow-up.

Abstract
Genetic biomarkers of neuroplasticity in deaf children treated with cochlear implantation (CI) might facilitate their clinical management, especially giving them better chances of developing proficient spoken language. We investigated whether carrying certain variants of the genes encoding matrix metalloproteinase MMP9 and neurotrophin brain-derived neurotrophic factor (BDNF), involved in synaptic plasticity, can be taken as prognostic markers of how well auditory skills might be acquired. Association analysis of functional MMP9 rs3918242 and BDNF rs6265 variants and the child’s auditory development measured at CI activation and 1, 5, 9, 14, and 24 months post CI activation with LittlEARS Questionnaire (LEAQ) was conducted in a group of 100 children diagnosed with DFNB1-related deafness, unilaterally implanted before the age of 2 years. Statistical analysis in the subgroup implanted after 1 year of life (n = 53) showed significant association between MMP9 rs3918242 and LEAQ scores at 1 month (p = .01), at 5 months (p = .01), at 9 months (p = .01), and at 24 months (p = .01) after CI activation. No significant associations in the subgroup implanted before 1 year of life were observed. No significant associations between the BDNF rs6265 and LEAQ score were found. Multiple regression analysis (R2 = .73) in the subgroup implanted after 1 year of life revealed that MMP9 rs3918242 was a significant predictor of treatment outcome. In conclusion, C/C rs3918242 MMP9 predisposes their deaf carriers to better CI outcomes, especially when implanted after the first birthday, than carriers of C/T rs3918242MMP9.

Psychomotor development of 4-year-old deaf children with cochlear implants: Three case studies. Int J Pediatr Otorhinolaryngol 2021; 141:110570. [PMID: 33348125 DOI: 10.1016/j.ijporl.2020.110570] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Revised: 11/11/2020] [Accepted: 12/14/2020] [Indexed: 11/22/2022]
Abstract
OBJECTIVES Hearing is one of our most important senses, and hearing ability has an enormous impact on a child's psychomotor development. Children with auditory perception disorders may show abnormal development in terms of speech, language, and communication skills, as well as other disorders involving the cognitive sphere, social-emotional interactions, and motor development. This paper describes different paths of psychomotor development in three 4-year-old children. All were born with bilateral profound sensorineural hearing loss and were implanted early on with a cochlear implant. A longitudinal study of the children's psychomotor development was done for 3 years from the time of cochlear implantation. METHODS We present three children with congenital, profound bilateral sensorineural hearing loss. Psychomotor development was evaluated using the Children Development Scale (CDS) and the Psychomotor Development Evaluation Cards (PDEC). The three children were: Girl A (4 years 2 months 17 days) - a user of one CI, last assessment of psychomotor development (PDEC) was 37 months after CI activation; Boy B (4 years 3 months 21 days) - a user of two CIs, last assessment of psychomotor development (PDEC) was 39 months after activation of first CI; Boy C (4 years 1 month 5 days) - user of two CIs, last assessment of psychomotor development (PDEC) was 36 months after activation of the first CI. RESULTS Analysis of the results from Girl A showed very poor dynamics of development from the age of 12 months, when the first CDS evaluation was performed, up to the PDEC evaluation performed at age 4 years. The CDS score of Boy B showed a very high level of psychomotor development. The PDEC evaluation performed after 39 months of using the first CI showed that the psychomotor development of Boy B was consistent with his chronological age. Boy C presented an average level of psychomotor development (compared to typically developing children) in his CDS scores in the perioperative period and then at 4, 9, and 14 months after cochlear implantation. After 24 months, his CDS scores showed a high level of psychomotor development. After 3 years of CI use, the PDEC evaluation showed that Boy C had an average score in five tested areas, a high score in the area of fine motor skills and lateralization, and a low score in knowledge and learning competencies. CONCLUSIONS Children with bilateral profound hearing loss can present different paths of psychomotor development. Children who receive a CI may show an age-appropriate level of psychomotor development compared to typically developing children. However, a hearing, speech, and language rehabilitation specialist responsible for the child still needs to perform regular checkups to monitor all areas of psychomotor development. Also, the effects of the deaf child's environmental determinants on psychomotor development should be studied in detail. These determinants include the parents' emotional state, the parents' involvement in the child's rehabilitation, the family's quality of life, and the presence of deaf siblings. In particular, the difficulties encountered by the mother (or father) in being the parent of a deaf child may hinder the family from receiving adequate support.
