Expert-opinion-based guidance for the care of children with lysosomal storage diseases during the COVID-19 pandemic: An experience-based Turkey perspective.

This expert-opinion-based document was prepared by a group of specialists in pediatric inherited metabolic diseases and infectious diseases including administrative board members of Turkish Society for Pediatric Nutrition and Metabolism to provide guidance for the care of children with lysosomal storage disorders (LSDs) during the COVID-19 pandemic in Turkey. The experts reached consensus on key areas of focus regarding COVID-19-based risk status in relation to intersecting immune-inflammatory mechanisms and disease patterns in children with LSDs, diagnostic virus testing, particularly preventive measures and priorities during the pandemic, routine screening and diagnostic interventions for LSDs, psychological and socioeconomic impact of confinement measures and quarantines and optimal practice patterns in managing LSDs and/or COVID-19. The participating experts agreed on the intersecting characteristics of immune-inflammatory mechanisms, end-organ damage and prognostic biomarkers in LSD and COVID-19 populations, emphasizing the likelihood of enhanced clinical care when their interaction is clarified further studies addressing certain aspects related to immunity, lysosomal dysfunction and disease pathogenesis.

Recommendations on phenylketonuria in Turkey.

Background: Phenylketonuria (PKU), is an autosomal recessive disease leading to the conversion defect of phenylalanine (Phe) into tyrosine. Severe neurocognitive and behavioral outcomes are observed in untreated cases. The present paper aims to review clinical experiences and expert recommendations in diagnosis, treatment, and follow-up of pediatric PKU patients in Turkey.

Diagnostic value of plasma lysosphingolipids levels in a Niemann-Pick disease type C patient with transient neonatal cholestasis.

Objectives: Niemann-Pick disease type C (NPC) is a lysosomal storage disease due to impaired intracellular lipid trafficking caused by biallelic pathogenic variants in or genes. NPC is classified according to the age of onset of neurological manifestations. Cholestatic liver disease can be transient or lead to liver failure.

Liver involvement in neuroblastoma amplified sequence gene deficiency is not limited to acute injury: Fibrosis silently continues.

Biallelic mutations in neuroblastoma amplified sequence gene (NBAS) is a rare disease which is characterized by recurrent liver failure (RALF). We reported the novel mutations, clinical characteristics and long-term outcomes of 5 patients with novel biallelic NBAS variants. Four patients (80%) had acute, episodic liver crises (LC) triggered by fever, with a median age of onset of 8.

Glycogen storage disease type XII; an ultra rare cause of hemolytic anemia and rhabdomyolysis: one new case report.

Objectives: Aldolase A deficiency also known as glycogen storage disease (GSD) XII, is an ultra rare autosomal recessively inherited GSD, associated with hemolytic anemia and rhabdomyolysis.

Case Presentation: Here, we first report a patient with dermatological findings, hemodialysis requirement for rhabdomyolysis, and a novel likely pathogenic c.971C>T (p.

Brown Vialetto Van Laere syndrome: presenting with left ventricular non-compaction and mimicking mitochondrial disorders.

Background: Brown-Vialetto-Van Laere syndrome (BVVLS) is a rare, treatable neurodegenerative disorder with a variable clinical presentation, caused by mutations in three different riboflavin transporter genes.

Case: An 11-year-old-boy presented with respiratory insufficiency and a rapidly progressive muscle weakness. He was the fifth child of a consanguineous marriage with a medical history of hearing loss.

Clinical Features and Molecular Genetics of Autosomal Recessive Ataxia in the Turkish Population.

Background: Autosomal recessive cerebellar ataxias (ARCAs) are a heterogeneous group of inherited neurodegenerative disorders. The aim of this study was to present the clinical and genetic features of patients with ataxia complaints and those genetically diagnosed with ARCAs.

Materials And Methods: Thirty-one children with ARCA were retrospectively analyzed.

ASAH1 pathogenic variants associated with acid ceramidase deficiency: Farber disease and spinal muscular atrophy with progressive myoclonic epilepsy.

Farber disease and spinal muscular atrophy with progressive myoclonic epilepsy are a spectrum of rare lysosomal storage disorders characterized by acid ceramidase deficiency (ACD), resulting from pathogenic variants in N-acylsphingosine amidohydrolase 1 (ASAH1). Other than simple listings provided in literature reviews, a curated, comprehensive list of ASAH1 mutations associated with ACD clinical phenotypes has not yet been published. This publication includes mutations in ASAH1 collected through the Observational and Cross-Sectional Cohort Study of the Natural History and Phenotypic Spectrum of Farber Disease (NHS), ClinicalTrials.

Defining clinical subgroups and genotype-phenotype correlations in NBAS-associated disease across 110 patients.

Purpose: Pathogenic variants in neuroblastoma-amplified sequence (NBAS) cause an autosomal recessive disorder with a wide range of symptoms affecting liver, skeletal system, and brain, among others. There is a continuously growing number of patients but a lack of systematic and quantitative analysis.

Methods: Individuals with biallelic variants in NBAS were recruited within an international, multicenter study, including novel and previously published patients.

Analysis of the caregiver burden associated with Sanfilippo syndrome type B: panel recommendations based on qualitative and quantitative data.

Background: Sanfilippo syndrome type B (Sanfilippo B) belongs to a group of rare lysosomal storage diseases characterized by progressive cognitive decline from an early age, acute hyperactivity, and concomitant somatic symptoms. Caregivers face a unique set of challenges related to the complex nature of Sanfilippo B, but the burden and impact on quality of life (QoL) of caregivers is poorly defined and best practice guidance for clinicians is lacking.

Methods: An international clinical advisors meeting was convened to discuss key aspects of caregiver burden associated with Sanfilippo B based on findings from qualitative and quantitative research undertaken to identify and quantify the nature and impact of the disease on patients and caregivers.

The effect of an antifibrotic agent, pirfenidone, on penile erectile function in an experimental rat model of ischemic priapism.

To date, no effective medical approach for the treatment of erectile dysfunction (ED) secondary to ischemic priapism (IP) has been described. The aim of this study was to evaluate the anti-inflammatory, antifibrotic, and antioxidant effects of pirfenidone (PFD) on cavernosal tissue in a rat model of IP. Forty-eight male albino rats aged 8-10 months, with mean weights of 410 ± 18.

A possible biomarker of neurocytolysis in infantile gangliosidoses: aspartate transaminase.

Gangliosidoses (GM1 and GM2 gangliosidosis) are rare, autosomal recessive progressive neurodegenerative lysosomal storage disorders caused by defects in the degradation of glycosphingolipids. We aimed to investigate clinical, biochemical and molecular genetic spectrum of Turkish patients with infantile gangliosidoses and examined the potential role of serum aspartate transaminase levels as a biomarker. We confirmed the diagnosis of GM1 and GM2 gangliosidosis based on clinical findings with specific enzyme and/or molecular analyses.

Can untreated PKU patients escape from intellectual disability? A systematic review.

Background: Phenylketonuria (PKU) is often considered as the classical example of a genetic disorder in which severe symptoms can nowadays successfully be prevented by early diagnosis and treatment. In contrast, untreated or late-treated PKU is known to result in severe intellectual disability, seizures, and behavioral disturbances. Rarely, however, untreated or late-diagnosed PKU patients with high plasma phenylalanine concentrations have been reported to escape from intellectual disability.

Late-Onset Leigh Syndrome due to Mutation in a 10-Year-Old Boy Initially Presenting with Ataxia.

Leigh syndrome (LS) is a progressive neurodegenerative disease caused by either mitochondrial or nuclear DNA mutations resulting in dysfunctional mitochondrial energy metabolism. The onset of clinical features is typically between 3 and 12 months of age; however, a later onset has been described in a few patients. Complex I deficiency is reported to be the most common cause of mitochondrial disorders.
