Mucopolysaccharidosis type VI, Maroteaux-Lamy syndrome is a lysosomal storage disorder with progressive, multisystem involvement caused by deficiency of the lysosomal enzyme N-acetylgalactosamine-4-sulfatase leading to accumulation of the glycosaminoglycan, keratan sulfate. Enzyme replacement therapy (ERT) has been shown to clinically benefit affected individuals. A combined treatment regime of ERT and hemopoietic stem cell transplantation (HSCT) has led to reduced morbidity and mortality in patients with MPS I. We have demonstrated that a treatment regime of ERT combined with HSCT in a 3-year-old girl with MPS VI provided similar benefit. This treatment regimen should be considered in the management of selected patients with MPS VI. Neither HSCT nor ERT can correct or completely prevent progression of the musculoskeletal complications. Long-term follow-up and regular assessments for these complications is necessary.

Excessive inorganic trace elements are added to livestock and poultry feed to meet the needs of animals, accompanied by frequent occurrence of excretion and gastrointestinal stress. Replacing inorganic trace elements with organic trace elements provides a promising solution to alleviate these problems. Therefore, this study aimed to assess the impact of replacing all inorganic trace elements (ITMs) in feed on the growth performance, meat quality, serum parameters, trace element metabolism, and gut microbiota of finishing pigs.

Mucopolysaccharidosis type I (MPS I) is a metabolic disorder characterized by a deficiency in α-l-iduronidase (IDUA), leading to impaired glycosaminoglycan degradation. Current approved treatments seek to restore IDUA levels via enzyme replacement therapy (ERT) and/or hematopoietic stem cell transplantation (HSCT). The effectiveness of these treatment strategies in preventing neurodegeneration is limited due to the inability of ERT to penetrate the blood-brain barrier (BBB) and HSCT's limited CNS reconstitution of IDUA levels.

Purpose: Hip fractures in elderly individuals are associated with high mortality rates, even with advanced treatment options. Identifying factors correlated with mortality could guide potential preventive strategies. Elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels, as well as the AST/ALT ratio (AAR), have been associated with mortality in various diseases, but their association with hip fracture mortality remains underexplored.

Neuronal ceroid lipofuscinosis type 2 (CLN2) is a rapidly progressive neurodegenerative disorder leading to premature mortality. Ambulatory CLN2 patients typically receive standard of care treatment through biweekly intracerebroventricular (ICV) enzyme replacement therapy (ERT) involving recombinant human tripeptidyl peptidase 1, known as cerliponase alfa (Brineura, Biomarin Pharmaceuticals). This study longitudinally assessed the impact of ICV cerliponase alfa ERT on gait, and postural control across a two-year span in two siblings diagnosed with atypical CLN2 disease.

Introduction: alkaptonuria is a rare hereditary metabolic disorder which is characterized by deficiency of the enzyme homogentisate 1,2 dioxygenase, which is responsible for the oxidation and renal elimination of homogentisic acid (HGA), which causes its accumulation. The excessive accumulation of HGA results in ochronosis and ochronotic arthropathy, which mainly affects the thoracolumbar spine and the large joints, leading to the need for joint replacement seeking to improve function and quality of life.
Clinical Case: hereby is presented a 67-years-old female patient with history of alkaptonuria with diffuse painful right hip of 4 years of evolution.
