Disease manifestations encompass skeletal hypomineralization with rickets and lung hypoplasia, vitamin B6-dependent seizures, craniosynostosis, and premature loss of deciduous teeth. The clinical presentation can comprise failure to thrive with muscular hypotonia, delayed motor development, and gait disturbances later in childhood. In adults, pseudofractures are a characteristic indicator of severely compromised enzyme activity, but non-canonical symptoms like generalized musculoskeletal pain, weakness, and fatigue, frequently accompanied by neuropsychiatric and gastrointestinal issues are increasingly recognized as key findings in patients with HPP. The diagnosis is based on clinical manifestations in combination with persistently low alkaline phosphatase (ALP) activity, elevated levels of ALP substrates, specifically inorganic pyrophosphate (PPi), pyridoxal 5'-phosphate (PLP) or urine phosphoethanolamine (PEA), and genetic confirmation of a causative ALPL variant. Considering the wide range of manifestations, treatment must be multimodal and tailored to individual needs. The multidisciplinary team for comprehensive management of HPP patients should include expertise to ensure disease state metabolic and musculoskeletal treatment, dental care, neurological and neurosurgical surveillance, pain management, physical therapy, and psychological care. Asfotase alfa as first-in-class enzyme replacement therapy (ERT) for HPP has been shown to improve survival, rickets, and functional outcomes in severely affected children, but further research is needed to refine how enzyme replacement can also address emerging manifestations of the disease. Prospectively, further elucidating the pathophysiology behind the diverse clinical manifestations of HPP is instrumental for improving diagnostic concepts, establishing novel means for substituting enzyme activity, and developing integrative, multimodal care.</p>","PeriodicalId":9601,"journal":{"name":"Calcified Tissue International","volume":"116 1","pages":"46"},"PeriodicalIF":3.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11885340/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143566016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the high prevalence of these conditions, translational research in this field is far from optimal, highlighting the need for stronger collaboration between basic and clinical scientists. This paper, authored by members of the basic and clinical action groups of the European Calcified Tissue Society (ECTS) and endorsed by the Board of the ECTS, examines the key barriers to effective translational research in musculoskeletal diseases, including clinician workload, differences in professional language and culture, physical distance between research sites, and insufficient interdisciplinary funding. Through interviews with eight institutional managers across five European countries, we observed that in some institutions, the collaboration between basic scientists and clinicians was regarded as no concern (but with room for improvement), and in most institutions it was recognised as a serious issue. We found consensus on the importance of collaboration yet identified discrepancies in the provision of structural and financial support. Based on these findings, we propose strategic initiatives to bridge the gap between basic and clinical research. Suggested measures include dedicated translational funding, integrated research facilities, collaborative scientific forums, strategic collaborations, establishment of physician-scientists, and, finally, bringing basic and clinical researchers together in the same building or even in a combined department. Notable successes, such as the development of the anti-osteoporotic drugs, romosozumab and denosumab, underscore the value of a coordinated approach and exemplify how shared insights between laboratory research and clinical practice can lead to impactful therapeutic advances. Moving forward, we advocate for institutional commitments to foster a robust translational research environment, as well as tailored funding initiatives to support such efforts.

The administration of bisphosphonates (BPs) in children with OI increases bone density. This antiresorptive inhibits osteoclast action, thus altering physiological processes, in which osteoclasts play important roles, such as the eruptive process. The aim of this investigation was to study the eruptive process (dental development of permanent dentition, resorption of temporary dentition, and alveolar eruption of the first permanent molar) in children with OI medicated with BPs and to compare the results with those of a control group. In total, 34 panoramic radiographs of children with OI [mean chronological age of 8.43 (± 1.77)] who were medicated with BPs for a period of one year or more were studied and 367 panoramic radiographs of healthy children [mean chronological age of 9.19 (± 1.62)] were used as controls. The Demirjian method was used to study the dental development of the seven permanent teeth in the third quadrant. Alveolar eruption of the first permanent molar was considered when perforation of the alveolar bone was produced. The Haavikko method was used to study the root resorption of the five primary teeth in the third quadrant, and software (PixelStick®) was used to measure the lengths of the mesial and distal roots of the primary molars. The cumulative dose of BPs was obtained by mathematically calculating the total dosage received (mg)/weight (kg) and multiplying the relative potency of the medication. The Mann‒Whitney U test was used for comparisons, and p < 0.05 indicated statistical significance. A delay of 0.95 points in dental development and delayed exfoliation of primary dentition between 1.31 and 1.66 years were described in the study group. A root resorption delay of 11.8% was described among the 5 primary teeth of 23.3% among the single-rooted teeth and of 5.6% among the two-rooted teeth in children with OI medicated with BFs (p < 0.05). Delayed alveolar eruption of the first permanent molar at 0.31 years of age was found in children with OI medicated with BFs. We detected delayed tooth development at one stage of maturation in the study group, which was clinically imperceptible. The dental age (≤ 0.55 years) was greater than the chronological age in both groups. We also reported delayed exfoliation of the primary dentition (from 1.31 to 1.66 years), delayed root resorption of the primary dentition (11.8%), and delayed (from 1 mm to 1.25 mm) root resorption of the primary molars in the study group. Although the degree of dental development of the first permanent molar was similar between the two groups, we found delayed (0.31 years) alveolar eruption in the study group and a greater delay (0.44 years) in children whose cumulative dose of bisphosphonates exceeded 2000.</p>","PeriodicalId":9601,"journal":{"name":"Calcified Tissue International","volume":"116 1","pages":"37"},"PeriodicalIF":3.3,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143363762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
