Outcome of enzyme replacement therapy for hematological and visceral manifestations in children with acid sphingomyelinase deficiency: a single center experience in upper Egypt.
Article in Molecular and cellular pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThrombocytopenia is the most common hematologic manifestation of acid sphingomyelinase deficiency (ASMD). The introduction of enzyme replacement therapy (ERT) represents significant progress in the treatment landscape of this disorder. This study presents the largest pediatric case series of ASMD to date, providing valuable insights into the real-world application of ERT in affected children.
methodsTen children with ASMD (five with type B and five with type A/B) received ERT for one year. Growth parameters, complete blood counts, abdominal ultrasonography, liver function tests, lipid profiles, and neurological assessments were conducted at baseline and subsequently every three months. In addition, chest high-resolution computed tomography (HRCT) and dual-energy X-ray absorptiometry (DXA) were performed at baseline and repeated after one year.
resultsNo serious infusion-related reactions (IAR) were recorded. However, one patient developed a mild urticarial rash, while another experienced pyrexia. Anemia was present in all children at baseline. A significant increase in hemoglobin levels starting at week 12 (p = 0.02) with peak levels observed at week 50. Thrombocytopenia was present in 60% of patients at baseline. Platelet counts did not show a significant change at week 12 (p = 0.3), but a significant increase was observed after 24 weeks (p = 0.0196), and counts peaked at week 50 (p = 0.0057). There was a significant reduction in liver and spleen sizes, as well as lipid profile parameters. In addition, gradual improvements were observed in interstitial lung disease scores and bone mineral densities throughout the study course.
conclusionOur findings indicate that olipudase alfa provides significant benefits in key hematological and visceral clinical outcomes in pediatric patients with ASMD.
