Chronic acid sphingomyelinase deficiency diagnosed in infancy/childhood in Polish patients: 2024 update.
Background: Acid sphingomyelinase deficiency (ASMD) is an autosomal recessive lysosomal storage disease (LSD) associated with biallelic pathogenic variants in the sphingomyelin phosphodiesterase 1 (SMPD1) gene.
Objectives: The aim of this study was to provide the 2024 update on chronic visceral and neurovisceral ASMD diagnosed in the infancy/childhood in Polish patients.
Material and methods: All the patients diagnosed in the pediatric age (0-18 years) with ASMD, both chronic neurovisceral and visceral type, and then systematically followed up, were enrolled into the study.
Results: A total number of 7 patients were enrolled into the study. Four patients were previously reported. Two patients were newly recognized with ASMD - 1 with chronic visceral and 1 with chronic neurovisceral ASMD. Splenomegaly was noted in all the patients while a mild liver enlargement was observed in 4 of 7 patients. All patients presented with decreased high-density lipoprotein cholesterol (HDL-C) and decreased serum 25-hydroxy-vitamin D concentration while almost all (6 of 7) with hypercholesterolemia. Cherry-red spot was observed in 5 of 7 patients, including 1 patient with neurovisceral type. Seven various SMPD1 gene variants were identified and missense variants were the most common types of genetic lesions, comprising 71% of all alleles. In all the screened patients, lyso-sphingomyelin (lyso-SM) in dried blood spot (DBS) was found elevated; however, the greater values were observed for patients with chronic neurovisceral type.
Conclusion: Chronic acid sphingomyelinase deficiency (ASMD) is a slowly progressive disease. Pediatric ASMD is characterized by spleno-hepatomegaly, dyslipidemia (with decreased HDL-C as the most characteristic) and infiltrative (interstitial) lung disease. Both visceral and neurovisceral chronic ASMD patients could present with cherry-red spot. Both acid spingomyelinase activity and lyso-spingomyelin concentration in DBS should be regarded as a first-tier screening method into ASMD.
期刊介绍：
Advances in Clinical and Experimental Medicine has been published by the Wroclaw Medical University since 1992. Establishing the medical journal was the idea of Prof. Bogumił Halawa, Chair of the Department of Cardiology, and was fully supported by the Rector of Wroclaw Medical University, Prof. Zbigniew Knapik. Prof. Halawa was also the first editor-in-chief, between 1992-1997. The journal, then entitled "Postępy Medycyny Klinicznej i Doświadczalnej", appeared quarterly.
Prof. Leszek Paradowski was editor-in-chief from 1997-1999. In 1998 he initiated alterations in the profile and cover design of the journal which were accepted by the Editorial Board. The title was changed to Advances in Clinical and Experimental Medicine. Articles in English were welcomed. A number of outstanding representatives of medical science from Poland and abroad were invited to participate in the newly established International Editorial Staff.
Prof. Antonina Harłozińska-Szmyrka was editor-in-chief in years 2000-2005, in years 2006-2007 once again prof. Leszek Paradowski and prof. Maria Podolak-Dawidziak was editor-in-chief in years 2008-2016. Since 2017 the editor-in chief is prof. Maciej Bagłaj.
Since July 2005, original papers have been published only in English. Case reports are no longer accepted. The manuscripts are reviewed by two independent reviewers and a statistical reviewer, and English texts are proofread by a native speaker.
The journal has been indexed in several databases: Scopus, Ulrich’sTM International Periodicals Directory, Index Copernicus and since 2007 in Thomson Reuters databases: Science Citation Index Expanded i Journal Citation Reports/Science Edition.
In 2010 the journal obtained Impact Factor which is now 1.179 pts. Articles published in the journal are worth 15 points among Polish journals according to the Polish Committee for Scientific Research and 169.43 points according to the Index Copernicus.
Since November 7, 2012, Advances in Clinical and Experimental Medicine has been indexed and included in National Library of Medicine’s MEDLINE database. English abstracts printed in the journal are included and searchable using PubMed http://www.ncbi.nlm.nih.gov/pubmed.
