Coagulopathy in Neonates With Classic Galactosemia: A Life-Threatening Yet Underrecognized Complication.

Journal of pediatric health care : official publication of National Association of Pediatric Nurse Associates &amp; Practitioners2026 Feb 26

Classic galactosemia (CG) is a rare metabolic disorder caused by galactose-1-phosphate uridylyltransferase deficiency, leading to toxic metabolite accumulation and life-threatening complications such as failure to thrive, sepsis, and acute liver failure. We hypothesize that coagulopathy is an underrecognized complication of CG and that this gap is reflected by limited documentation in the medical literature. A PubMed literature review was conducted to identify articles describing coagulopathy in CG. We filtered for guidelines, meta-analyses, reviews, and systematic reviews. Our article screening followed PRISMA guidelines. Of 49 identified articles, 26/49 (53%) met inclusion criteria. Only 6/49 (12%) explicitly described coagulopathy in CG, and only 1/49 (2%) discussed management. These data supports our hypothesis that coagulopathy may be an underrecognized complication of CG by clinicians and identifies a gap in current medical literature. Improved early recognition of coagulopathy in neonates with CG could prevent delays in treatment and improve outcomes.

Pretreatment With a Selected Strain of Baker's Yeast, GY007, Prevents the Accumulation of Galactose Metabolites Following Dietary Galactose Exposure in a GALT-Null Rat Model of Classic Galactosemia.

Journal of inherited metabolic disease2025 Nov

The current standard of care for patients with classic galactosemia (CG) involves lifelong dietary restriction of high galactose foods, including most dairy products. Here, we present the results of a pilot study testing whether pretreatment with GY007, a strain of baker's yeast selected to metabolize galactose despite the presence of other sugars, would be sufficient to prevent the metabolic impact of dietary galactose exposure in a GALT-null rat model of CG. Specifically, we dosed cohorts of adolescent GALT-null rats with either (a) placebo alone, (b) placebo followed by galactose, or (c) GY007 yeast followed by galactose. All rats were treated 3 times daily for 8 consecutive days, for a combined daily dose of almost 27 mg galactose per rat. Wild-type rats dosed with placebo served as controls. All rats also had ad libitum access to water and chow that contained about 0.15% calories from galactose. Rats grew at the expected pace for the duration of the study regardless of treatment group. To test the metabolic efficacy of the GY007 pretreatment, we followed galactose, galactitol, and gal-1P longitudinally in blood, and at euthanasia in brain and liver. In both liver and red blood cells, most metabolites remained near placebo levels despite the galactose exposure, limiting our ability to test the efficacy of GY007 pretreatment in those tissues. However, in both plasma and brain, metabolites showed a significant elevation following galactose exposure, and this rise was prevented by pretreatment with GY007. These results demonstrate the potential of GY007 yeast to prevent the metabolic consequences of transient low-level dietary galactose exposure in GALT deficiency.

Myo-Inositol Deficiency, Structural Brain Changes, and Cerebral Perfusion Alterations in Classic Galactosemia: Preliminary Insights From a Multiparametric MRI Study.

Journal of inherited metabolic disease2025 Nov

Classic galactosemia is a rare metabolic disorder resulting from galactose-1-phosphate uridylyltransferase deficiency, which disrupts normal galactose metabolism, leading to toxic accumulation of galactose-1-phosphate and galactitol. Despite early dietary intervention, patients remain at risk for long-term neurological impairments, including cognitive deficits, motor speech disorders, and psychiatric conditions. The mechanisms driving these persistent abnormalities remain unclear. This study investigated brain metabolic and structural alterations in adults with classic galactosemia using advanced multiparametric MRI. Six patients (3 males, 3 females; mean age 34.0 ± 7.3 years) adhering to lifelong galactose-restricted diets and six age- and sex-matched controls underwent 3T and 7T MRI, including T1-weighted imaging, pseudo-continuous arterial spin labeling, and high-resolution MR spectroscopic imaging. Patients exhibited significantly lower myo-inositol (mIns) concentrations in cerebellum (p = 0.007), putamen (p = 0.023), and cerebral white matter (p = 0.001), reflecting a chronic mIns deficiency despite dietary management. Structural analyses revealed reduced volumes of white matter (p < 0.001), bilateral putamen (p < 0.038), and left thalamus (p = 0.044); alongside increased cortical thickness and reduced cortical surface area, indicating abnormal cortical maturation, particularly in regions associated with motor and cognitive processing. Additionally, cerebral blood flow was elevated in emotion-processing regions, including bilateral amygdala (p < 0.022) and thalamus (p < 0.038). These preliminary findings highlight persistent neurological alterations in classic galactosemia despite dietary management and suggest that chronic mIns deficiency may contribute to the pathophysiology. They underscore the need for larger, longitudinal studies to confirm these results, investigate potential correlations with clinical severity and biochemical markers, and explore therapeutic strategies aimed at modulating mIns metabolism.

Exit interviews with caregivers of pediatric patients with classic galactosemia to explore meaningfulness of changes in the ACTION-galactosemia kids trial.

Orphanet journal of rare diseases2025 Sep 30

Classic Galactosemia is a rare, autosomal recessive disease in which galactose is not metabolized properly due to severe deficiency/absence of the galactose-1-phosphate uridylyltransferase (GALT) enzyme, converting to an aberrant and toxic metabolite, galactitol. Living with the debilitating symptoms and long-term consequences of Classic Galactosemia creates a heavy burden on patients' and their families' lives. Objectives were to: (1) Evaluate the impact and burden of disease; (2) Qualitatively explore changes in patient symptoms following treatment; and (3) Document the meaningfulness of changes resulting from treatment with govorestat as assessed by the Caregiver Global Impression of Severity (CGIS) and Caregiver Global Impression of Change (CGIC) scales. The AT-007-1002 clinical trial involved a Phase 1/2 dose escalation component (Part A) followed by a Phase 3, randomized, double-blind, placebo-controlled long-term administration component (Part B) that evaluated potential clinical benefit. Exit Interviews were completed prior to unblinding of data. The in-depth, qualitative interviews were semi-structured, using a discussion guide, and conducted by either Zoom or GoToMeeting. Thirty-six caregiver interviews were conducted, capturing the experience of 37 pediatric patients (one caregiver had 2 patients enrolled in the study). Thematic analysis was undertaken to identify themes or patterns within the data. All analyses were conducted on blinded data. Following finalization of the analysis and report findings, post-hoc analysis of the unblinded data was then conducted to explore the meaningfulness of patients experience by treatment arm. This study confirms the substantial burden known to be associated with Classic Galactosemia in a pediatric population. The difficulties experienced were across multiple areas including cognitive function, behavior/social function, motor function, emotional function, communication, vision problems, ovarian insufficiency, sensory difficulties, and sleep problems. The interviews demonstrated that most patients (approximately two thirds) experienced an improvement in symptoms and impacts associated with classic galactosemia over the course of the trial. Nearly all caregivers reported that they perceived a 1-category change on the Caregiver Global Impression of Severity or Caregiver Global Impression of Change items, indicating severity and change respectively, was meaningful to them and the patient. Unblinded analysis of the exit interview data confirmed the patient experience reported by caregivers was different between the treatment arms, providing qualitative support for the treatment benefit of govorestat when compared to placebo. Furthermore, the qualitative data from caregivers provide in-depth insights of their unique lived experience that highlight the substantial impact that this improvement had on the caregiver's and the patient's quality of life. The improvements observed led to a reduction on the burden of Classic Galactosemia and may lead to a greater patient's greater independence. The exit interviews confirmed the burden of Classic Galactosemia disease across multiple domains. Qualitative investigation suggests that observed changes are meaningful to the patient and caregiver, and changes were more commonly reported in those receiving govorestat compared to placebo. Full clinical trial findings will be published separately.

Patterns of Penetrance and Expressivity of Long-Term Outcomes in Classic Galactosemia.

Journal of inherited metabolic disease2025 May

Long-term complications are common among patients with classic galactosemia (CG) and show both reduced penetrance and variable expressivity. Overall prevalence rates for complications in cognitive, motor, and speech/voice/language outcomes among US and European cohorts are known. However, age at presentation, whether these complications cluster, and what factors might associate with penetrance remain unknown. These gaps in knowledge limit prognostic accuracy for young patients and leave open the question of whether complications in different outcome domains may have shared modifiers. Here we addressed these questions using data from medical records and family survey responses from 164 patients and 77 controls. We found that for cases who experienced long-term complications, the median age at presentation of challenges in cognitive outcome was about 5 years, in motor outcome was about 3 years, and in speech/voice/language outcome was about 2 years. We also found highly significant clustering of complications in these three domains. Finally, we tested six factors for possible association with penetrance: history of severe neonatal symptoms, GALT genotype and predicted residual GALT activity, days of neonatal milk exposure, rigor of non-dairy galactose restriction in early childhood, peak red blood cell (RBC) galactose-1P level in infancy, and baseline RBC galactose-1P level in early childhood. Of these, only history of severe neonatal brain-related symptoms consistently associated with higher penetrance, and only detectable predicted residual GALT activity consistently associated with lower penetrance. Combined, these results substantially extend what is known about the natural history of long-term complications in CG.
