Achondroplasia (ACH) is a common inherited skeletal dysplasia (inherited dwarfism) that compromises quality of life across the lifespan. In 2021, vosoritide became the first approved precision therapy for ACH and is now available in more than 40 countries. Compared with prior symptomatic measures, vosoritide has demonstrated favorable efficacy and a reassuring safety profile. Nevertheless, existing international ACH guidelines largely emphasize complication management and symptomatic care, and there is no unified consensus on pharmacologic therapy. To address this gap, an international expert group developed the International Consensus Guidelines for the Implementation and Monitoring of Vosoritide Therapy in Patients with Achondroplasia providing systematic recommendations that span the continuum of care - from initial patient contact and pre-treatment assessment to medication counseling, injection training, and long-term outcome monitoring. These recommendations complement and refine current management and nursing protocols for individuals with ACH and offer practical guidance for clinicians across diverse regions. This article highlights key elements of the guideline to provide evidence-based support and clinical direction for healthcare professionals in China treating children with ACH using vosoritide.

Achondroplasia (ACH) is a common skeletal dysplasia in children, primarily caused by mutations in the fibroblast growth factor receptor 3 (FGFR3) gene. These mutations disrupt the process of endochondral ossification in different types of bones, including long bones of the limbs and vertebrae. Children with ACH typically present with short stature and may experience severe multi-system complications. The diagnosis of ACH is based on typical clinical manifestations, imaging features, and genetic testing results. Treatment options mainly include pharmacological interventions and surgical procedures aimed at improving height, as well as symptomatic management for associated complications. This article discusses both prenatal and clinical diagnostic approaches for ACH, as well as treatment strategies focused on enhancing height, aiming to deepen the understanding of this condition.

This paper summarizes the clinical features, causative genes and treatment progress of patients with rickets-like genetic diseases, including X-linked hypophosphatemic rickets (XLH), hypophosphatasia, achondroplasia, vitamin D-dependent rickets, pycnodysostosis and ectodermal dysplasia, who visited the pediatric or child health clinic due to the symptoms of rickets, including bow legs, delayed closure of the anterior fontanelle, and sparse hair. Children with XLH usually go to hospital for bow legs and short stature, and biochemical evaluation reveals significantly low serum phosphorus so it is easily diagnosed. This disease is treated using phosphate mixture and 1,25(OH)2D3, which is different from the treatment of nutritional vitamin D deficiency rickets. Hypophosphatasia is characterized by a significant decrease in serum alkaline phosphatase, as well as normal serum calcium and phosphorus. The disease is caused by mutations in TNSALP gene. Patients with achondroplasia show short-limbed dwarfism and special face in addition to bow legs, but with normal serum calcium, phosphorus and alkaline phosphatase. Bone X-ray and FGFR3 gene test contribute to the diagnosis. Vitamin D-dependent rickets is an autosomal recessive disease, and active vitamin D supplement is effective in treatment of the disease. Patients with pycnodysostosis may be first seen at hospital because of large anterior fontanelle; in addition, they also show obtuse mandibular angle, dental abnormalities and dysplastic nails, which are caused by mutations in TSK gene. Children with ectodermal dysplasia may see a doctor for sparse hair, and they are easily misdiagnosed with nutritional vitamin D deficiency rickets. Ectodermal dysplasia is related to EDA, EDAR, EDARADD and WNT 10A genes.
