Presentation

  • Abstract Neutral lipid storage disease with myopathy (NLSDM) presents with skeletal muscle myopathy and severe dilated cardiomyopathy in nearly 40% of cases.[ncbi.nlm.nih.gov]
  • RESULTS: All eight patients presented with developmental delay or regression during late infancy and later developed epilepsy, mostly intractable generalized tonic seizures.[ncbi.nlm.nih.gov]
  • The present review focuses on current available evidence that supports the incremental value of STE in the diagnostic and prognostic workup of LVH.[ncbi.nlm.nih.gov]
  • Here we describe two different clinical presentations of this disease: one case with a clear phenotype of familial hypercholesterolaemia and one case with hepatosplenomegaly from childhood onwards.[ncbi.nlm.nih.gov]

Pathologist
  • Due to low awareness of this condition among physicians including surgical pathologists, majority of the liver biopsies, especially from the adults are often misdiagnosed as non-alcoholic fatty liver disease/non-alcoholic steatohepatitis or cryptogenic[ncbi.nlm.nih.gov]

Workup

  • The present review focuses on current available evidence that supports the incremental value of STE in the diagnostic and prognostic workup of LVH.[ncbi.nlm.nih.gov]
  • The coexistence of hepatomegaly and hypoglycemia should prompt a workup that includes measurement of BG, lactate, uric acid, and hepatic profile including liver function studies, CK, plasma total and free carnitine, acylcarnitine profile, urinalysis,[nature.com]
Dyslipidemia
  • Moreover, even in GSD I patients with apparent dyslipidemia, no premature atherosclerosis was shown ( 22 ).[cjasn.asnjournals.org]

Treatment

  • However, due to the risks and exclusion criteria of this treatment additional therapies are required.[ncbi.nlm.nih.gov]
  • In conclusion, CMA impairment contributes to cell malfunction in cystinosis, highlighting the need for treatments complementary to current therapies that are based on decreasing lysosomal overload. 2015 The Authors.[ncbi.nlm.nih.gov]
  • CBZ at low anticonvulsive treatment levels led to rapid normalization of alanine-aminotransferase and decrease of caspase-cleaved and uncleaved cytokeratin-18 fragments (M30 and M65). These effects reversed after discontinuation of treatment.[ncbi.nlm.nih.gov]
  • The majority of LSDs lack a curative treatment. This is particularly true for LSDs severely affecting the CNS.[ncbi.nlm.nih.gov]
  • Prognosis and treatment of glycogen storage diseases vary by type, but treatment typically includes dietary supplementation with cornstarch to provide a sustained source of glucose for the hepatic forms of GSD and exercise avoidance for the muscle forms[merckmanuals.com]

Prognosis

  • Prognosis Prognosis is unfavorable for patients with perinatal onset and classic forms who do not undergo liver transplantation. Long-term prognosis for others depends on the extent, severity, and progression of the condition.[orpha.net]
  • In patients with LVH, subclinical left ventricular (LV) dysfunction despite normal ejection fraction (EF) may be present before the onset of symptoms, which portends a dismal prognosis.[ncbi.nlm.nih.gov]
  • Prognosis The prognosis of GSD is highly varied. Overall, the long-term prognosis depends on the extent, severity, and progression of the disease. GSDs are generally multisystem diseases, with many potential complications.[encyclopedia.com]
  • Prognosis For NLSDI/Dorfman-Chanarin disease, the severity of the disease is linked to the myopathy and any associated disorders (which may include ocular and cerebral involvement).[orpha.net]
  • Prognosis is good; adult patients have normal stature and minimal hepatomegaly.[ommbid.mhmedical.com]

Etiology

  • This case illustrates a rare etiology of storage disease that causes abnormal liver function tests.[ncbi.nlm.nih.gov]
  • Genetic etiology of congenital/infantile nystagmus remains largely unknown. This study aimed to identify genomic mutations in patients with infantile nystagmus and an associated disease network.[ncbi.nlm.nih.gov]
  • Etiology NLSDI/Dorfman-Chanarin disease is caused by mutations in the ABHD5 gene (3p21), NLSDM by mutations in the PNPLA2/ATGL gene (localized to 11p15.5).[orpha.net]
  • Etiology The disease is caused by mutations in the GBE1 gene (3p12) encoding GBE. GBE deficiency results in storage of abnormal glycogen that resembles an amylopectin-like structure (polyglucosan).[orpha.net]
  • Negative investigations for infection etiology, unbalanced chromosomal abnormalities and congenital major malformations (heart, kidneys and vascular system).[clinicaladvisor.com]

Epidemiology

  • This report expands the epidemiology of FSD and demonstrates idiosyncrasy in response to oral carbamazepine and/or ursodeoxycholic acid in FSD.[ncbi.nlm.nih.gov]
  • Summary Epidemiology The group of diseases is very rare and the prevalence is unknown (around 50 cases have been reported in medical literature, of which 3 had NLSDM) because of the vagueness of the descriptions.[orpha.net]
  • GSD I is typically treated with frequent small meals of carbohydrates and cornstarch to prevent low blood sugar, while other treatments may include allopurinol and human granulocyte colony stimulating factor. [21] Epidemiology [ edit ] Overall, according[en.wikipedia.org]

Pathophysiology

  • Although the exact pathophysiology is not exactly the same, it is astounding how many similar pathways are altered in all of these diseases.[ncbi.nlm.nih.gov]
  • Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test Glycogen storage diseases (GSDs) are a group of inherited metabolic conditions caused by deficiency of enzymes responsible for[mayomedicallaboratories.com]
  • This may exacerbate subtle energy deficiency which has been discussed to play a pathophysiological role in glycogenoses [ 21 ],[ 22 ].[ojrd.biomedcentral.com]
  • Manifestations Although single gene defects typically result in substrate accumulation, the precise underlying pathophysiologic mechanisms that lead to clinical symptoms are not entirely clear.[emedicine.medscape.com]

Prevention

  • High-molecular-weight PVP polymers are prevented from renal excretion and are retained in the reticuloendothelial system.[ncbi.nlm.nih.gov]
  • There is no way to prevent GSDs.[mda.org.au]
  • Weinstein’s research lab, located at UConn Health , focuses on ways to prevent the complications of the disease—and on discovering a cure.[connecticutchildrens.org]
  • A drug commonly prescribed to prevent transplant rejection -- rapamycin -- stimulated autophagy and improved liver size and function in animal models.[sciencedaily.com]
