Anaesthetic management of infants with glycogen storage disease type II: a physiological approach

Pompe or Glycogen Storage Disease type II (GSD-II) is a genetic disorder affecting both cardiac and skeletal muscle. Historically, patients with the infantile form usually die within the first year of life due to cardiac and respiratory failure. Recently a promising enzyme replacement therapy has resulted in improved clinical outcomes and a resurgence of elective anaesthesia for these patients. Understanding the unique cardiac physiology in patients with GSD-II is essential to providing safe general anaesthesia.     

Multidisciplinary management of an obstetric patient with glycogen storage disease type 3

A 22-year-old primiparous woman with known glycogen storage disease type 3a presented to our hospital during her 12th week of pregnancy. Glycogen storage disease type 3 is a rare inherited disorder resulting from a deficiency of the glycogen debranching enzyme, causing the accumulation of abnormal short-chain glycogen in liver, blood cells, myocardium and striated muscle. Symptoms improve after puberty but the increased metabolism of pregnancy predisposes to hypoglycaemia, ketosis and lactic acidosis. Cardiomyopathy, distal weakness and peripheral neuropathy may present after the third decade. The patient was managed antenatally with regular cornflour feeds and was scheduled for elective caesarean delivery. She presented in early labour at 38 weeks and delivered a healthy neonate by urgent caesarean delivery under spinal anaesthesia. Intravenous dextrose infusion and regular blood glucose monitoring were used during the perinatal period to prevent hypoglycaemia. An arterial line was inserted in the operating room for frequent blood sampling and to avoid muscle cramps which could be induced by the intermittent inflation of the automated blood pressure cuff. Obstetric, anaesthetic and neonatal outcomes were uneventful.     

Renal disease in an adult with type 1 glycogen storage disease

The renal disease in an adult woman with Type 1 glycogen storage disease (GSD) is reported. Since she was 15 years old, several episodes of gouty arthritis had developed. At the age of 18, proteinuria was pointed out. Hepatomegaly, renomegaly out of proportion to the impairment of renal function, hyperuricemia, hyperlipidemia, fasting hypoglycemia and lactic acidemia were observed. The diagnosis of GSD was established on the basis of a glucose tolerance test, glucagon test and liver biopsy. The findings of renal biopsies performed at the ages of 24 and 27 years old suggested that glomerular damage might have preceded the tubulo-interstitial lesion.     

Anaesthetic management for a patient with Dejerine-Sottas disease and asthma

Dejerine-Sottas disease is a very uncommon degenerative disease of the peripheral nervous system. The details of perioperative anaesthetic management are discussed including the use of epidural anaesthesia, with supplemental intravenous anaesthesia and an LMA.     

Multiple adenomas and hepatocellular carcinoma in a renal transplant patient with glycogen storage disease type 1a (von Gierke disease)

We report on a 42-year-old female patient with glycogen storage disease type 1a (von Gierke disease, GSD 1a) who developed hepatic adenomas and finally a hepatocellular carcinoma 10 years after renal transplantation. The tumor was resected; however, the patient died 6 months later as a result of fulminant carcinoma recurrence. In patients who have GSD 1a with terminal renal failure, combined liver and kidney transplantation may be considered at an early stage of the disease.     

Hypertension in a child with type IA glycogen storage disease

Hypertension and proteinuria were observed in a 2-year-old child with type IA (von Gierke's) glycogen storage disease (GSD). She had evidence of hyperfiltration and had elevated selective renal vein renins. On renal biopsy, increased mesangial cell matrix and cellularity were observed with focal thickening and irregularity of the basement membrane. This case may be representative of the early renal findings in type IA GSD.     

Anaesthetic management of an obstetric patient with Pompe disease

Pompe disease (Glycogen storage disease type II) leads to abnormal glycogen deposition in various vital organs resulting in multiple systemic sequelae. We present the anaesthetic management for caesarean section of a 31-year-old parturient with known Pompe disease. The parturient had symptoms and signs of respiratory dysfunction and the pregnancy was complicated by preeclampsia. She underwent urgent caesarean section under regional anaesthesia resulting in the birth of a healthy baby girl. To our knowledge, this is the first reported case of both spinal anaesthesia for caesarean section and successful live birth in a patient with Pompe disease.     

Anaesthetic management of a patient with achondroplasia

A 12-year-old girl diagnosed with achondroplasia was admitted for bilateral ear surgery and adenotonsillectomy. She had classical symptoms and signs of upper airway obstruction, which is often seen in patients with achondroplasia. We describe the anaesthetic management of this patient, emphasizing the airway difficulties encountered and their anaesthetic implications.     

Anaesthetic management of a patient with microvillus inclusion disease for intestinal transplantation

We report the anaesthetic management of a 3-year-old-child with microvillus inclusion disease undergoing isolated small bowel transplantation. He required long-term total parenteral nutrition which was complicated with numerous episodes of catheter related sepsis. This resulted in thrombosis of the major blood vessels which critically restricted vascular access available for intravenous nutrition, becoming a life-threatening condition for the patient. Haemodynamic, respiratory parameters and urinary output were well preserved throughout the procedure. Besides a transitory increase in potassium following graft revascularization, biochemical changes were small. Anaesthetic management included comprehensive preoperative assessment, central venous angiography to depict accessibility of central and peripheral veins, assurance of additional vascular access through the intraoperative catheterization of the left renal vein, perioperative epidural analgesia and preservation of splanchnic perfusion to ensure implant viability.     

Effect of liver transplantation on hepatic glucose metabolism in a patient with type I glycogen storage disease

BACKGROUND: In type I glycogenosis, mutation of the glucose-6-phosphatase gene results in absent glucose-6-phosphatase activity in liver cells leading to fasting hypoglycemia. Liver transplantation is expected to normalize glucose homeostasis. METHODS: Endogenous glucose production (6,6 2H2 glucose) was measured after an overnight fast and during exogenous 13C-labeled glycerol infusion in a patient with glycogenosis type I 24 months after liver transplantation and in a group of healthy subjects. RESULTS: Compared with healthy subjects, the glycogenosis patient had normal fasting glucose production and glucose and insulin concentrations after liver transplantation, but mildly elevated plasma glucagon concentrations. Gluconeogenesis from exogenous glycerol (13C glucose synthesis) was similar and did not lead to enhancement of glucose production in both healthy controls and the patient. CONCLUSIONS: Liver glucoregulatory function is restored by orthotopic liver transplantation in type I glycogenosis.     

Perioperative management of benign hepatic tumors in patients with glycogen storage disease type Ia

Glycogen storage disease type Ia (GSD-Ia; von Gierke disease) is an inherited disorder caused by glucose-6-phosphatase deficiency, and there have been some reports of hepatic tumors in patients with this disease. We report two patients with benign hepatic tumors with GSD-Ia. One is a 19-year-old man who underwent segmentectomy 4 for a focal nodular hyperplasia, and the other is a 31-year-old woman who underwent segmentectomies 3, 5, and 6 for hepatic adenomas. Two significant perioperative complications, resulting from the carbohydrate metabolic disorders, hypoglycemia and metabolic acidosis, occurred in both patients. We managed the metabolic complications successfully by administering a sufficient volume of glucose intravenously. Close perioperative monitoring of blood glucose and lactate concentrations is essential in the perioperative management of patients with GSD-Ia. The intravenous administration of glucose, starting with a smaller dose and then increasing the dose, is adequate management for lactic acidosis with or without hypoglycemia during the perioperative period.     

Anaesthetic management of a patient with familial amyloid polyneuropathy of the Portuguese type

Although familial amyloid polyneuropathy of the Portuguese type (FAP-PT) was first described in 1952, there is little in the medical literature detailing the anaesthetic management of such patients. FAP-PT is a disease with multiple clinical manifestations which include disturbances of sensibility, progressive paresis starting in the lower extremities, autonomic dysfunction, cardiac conduction disturbances, gastro-intestinal disorders, nephrotic syndrome, sexual and sphincter disorders, extreme emotionalism and apprehension. Several intermingling problems have to be considered in the anaesthetic management of each individual case. In our patient a sinus dysrhythmia resolved after isoflurane and this seems to be a good choice for general anaesthesia in patients with FAP-PT, if they are in an early stage of heart involvement.
