Abstract
Glycogen storage disease (GSD) 1b is a metabolic disorder characterized by a deficiency of glucose 6-phosphate transporter and neutrophil alterations, which are reduced in number and functionally impaired. The present study aimed at investigating neutrophil dysfunction correlating submembrane and cytoskeletal changes at different ages with or without granulocyte-colony stimulating factor (G-CSF) treatment. GSD1b neutrophils showed reduced expression and diffused localization of focal adhesion kinase (FAK) and actin. No abnormalities were observed in GSD1a patient neutrophils. Gelsolin was also slightly reduced in neutrophils of GSD1b patients. When patients were treated for at least 3 months with G-CSF, the neutrophil number and the expression of FAK and actin were significantly increased. Granulocyte colony-stimulating factor treatment was similarly effective when performed in 1 year old patients. FAK auto- and IL-8-mediated phosphorylations were already affected as early as 1 year of age. G-CSF treatment also improved this alteration. Our data suggest that neutrophil dysfunction in GSD1b patients might be related to functional impairment and disorganization of proteins of the sub-membrane apparatus, and that G-CSF treatment counteracts neutropenia and prevents the progressive alterations of neutrophil sub-membrane proteins.

Abstract
Glucose-6-phosphatase, an enzyme localized in the endoplasmic reticulum (ER), catalyzes the hydrolysis of glucose-6-phosphate (G6P) to glucose and inorganic phosphate. In humans, there are three differentially expressed glucose-6-phosphatase catabolic genes (G6PC1-3). Recently, it has been shown that mutations in the G6PC3 gene result in a syndrome associating congenital neutropenia and various organ malformations. The enzymatic function of G6PC3 is dependent on G6P transport into the ER, mediated by G6P translocase (G6PT). Mutations in the gene encoding G6PT result in glycogen storage disease type-1b (GSD-1b). Interestingly, GSD-1b patients exhibit a similar neutrophil dysfunction to that observed in G6PC3-deficient patients. To better understand the causes of neutrophil dysfunction in both diseases, we have studied the neutrophil nicotinamide adenine dinucleotide phosphate (NADPH) oxidase of patients with G6PC3 and G6PT syndromes. Unexpectedly, sodium dodecyl sulfate-polyacrylamide gel electrophoresis experiments indicated hypo-glycosylation of gp91(phox), the electron-transporting component of the NADPH oxidase, in all of these patients. Rigorous mass spectrometric glycomic profiling showed that most of the complex-type antennae which characterize the neutrophil N-glycome of healthy individuals were severely truncated in the patients' neutrophils. A comparable truncation of the core 2 antenna of the O-glycans was also observed. This aberrant neutrophil glycosylation is predicted to have profound effects on the neutrophil function and merit designation of both syndromes as a new class of congenital disorders of glycosylation.

Abstract
We present a 23-year-old female with Glycogen storage disease Ib (GSD Ib) who was diagnosed with ulcerative colitis-like inflammatory bowel disease (IBD) at 7 years of age. G-CSF therapy reversed the IBD, was required to maintain IBD remission and was well tolerated. Neutrophil functions at time of diagnosis showed impaired chemotaxis but normal superoxide anion production and bactericidal activity. Ulcerative colitis-like IBD may also be seen in GSD Ib and is responsive to G-CSF therapy. Neutrophil dysfunction is variable among patients with GSD Ib.

Abstract
Glycogen storage disease type Ib is a rare inherited metabolic disorder that is caused by a deficiency of glucose-6-phosphate translocase with consequent accumulation of glycogen. The purpose of this study is to report a case affected by glycogen storage disease type Ib in which unusual oral findings were evident and to review the pertinent literature. The disease presents with failure to thrive, hepatomegaly, hypoglycemia, hyperlacticacidemia, neutropenia, and neutrophilic dysfunction causing increased susceptibility to recurrent infections. Common intraoral manifestations are dental caries, gingivitis, periodontal disease, delayed dental maturation and eruption, oral bleeding diathesis, and oral ulcers. Conversely, unusual oral lesions were observed in this case as hyperplastic-hypertrophic gingiva and giant cell granulomatous epulis. The treatment with granulocyte colony-stimulating factor markedly increased the neutrophil counts and reduced the frequency of infections and inflammations. Proper evaluation of the patient's oral condition, a program of preventive measures, and suitable medical consultation are important to minimize and avoid long-term complications.

Abstract
Glucose-6-phosphatase (G6Pase), an enzyme found mainly in the liver and the kidneys, plays the important role of providing glucose during starvation. Unlike most phosphatases acting on water-soluble compounds, it is a membrane-bound enzyme, being associated with the endoplasmic reticulum. In 1975, W. Arion and co-workers proposed a model according to which G6Pase was thought to be a rather unspecific phosphatase, with its catalytic site oriented towards the lumen of the endoplasmic reticulum [Arion, Wallin, Lange and Ballas (1975) Mol. Cell. Biochem. 6, 75--83]. Substrate would be provided to this enzyme by a translocase that is specific for glucose 6-phosphate, thereby accounting for the specificity of the phosphatase for glucose 6-phosphate in intact microsomes. Distinct transporters would allow inorganic phosphate and glucose to leave the vesicles. At variance with this substrate-transport model, other models propose that conformational changes play an important role in the properties of G6Pase. The last 10 years have witnessed important progress in our knowledge of the glucose 6-phosphate hydrolysis system. The genes encoding G6Pase and the glucose 6-phosphate translocase have been cloned and shown to be mutated in glycogen storage disease type Ia and type Ib respectively. The gene encoding a G6Pase-related protein, expressed specifically in pancreatic islets, has also been cloned. Specific potent inhibitors of G6Pase and of the glucose 6-phosphate translocase have been synthesized or isolated from micro-organisms. These as well as other findings support the model initially proposed by Arion. Much progress has also been made with regard to the regulation of the expression of G6Pase by insulin, glucocorticoids, cAMP and glucose.

Abstract
Glycogen storage disease type 1a (GSD 1a) is caused by a deficiency in microsomal glucose-6-phosphatase (G6Pase). A variant (GSD 1b) is caused by a defect in the transport of glucose-6-phosphate (G6P) into the microsome and is associated with chronic neutropenia and neutrophil dysfunction. Mutually exclusive mutations in the G6Pase gene and the G6P transport gene establish GSD la and GSD 1b as independent molecular processes and are consistent with a multicomponent translocase catalytic model. A modified translocase/catalytic unit model based on biochemical data in a G6Pase knockout mouse has also been proposed for G6Pase catalysis. This model suggests coupling of G6Pase activity and G6P transport. A 5-mo-old girl with hypoglycemia, hepatomegaly, and lactic acidemia was diagnosed with GSD 1a. She also developed neutropenia, neutrophil dysfunction, and recurrent infections characteristic of GSD 1b. Homozygous G188R mutations of the G6Pase gene were identified, but no mutations in the G6P translocase gene were found. We have subsequently identified a sibling and two unrelated patients with similar genotypic/phenotypic characteristics. The unusual association of neutrophil abnormalities in patients with homozygous G188R mutations in the G6Pase gene supports a modified translocase/catalytic unit model.

Abstract
OBJECTIVE To investigate the incidence, the severity, and the course of neutropenia, neutrophil dysfunction, and inflammatory bowel disease (IBD) in glycogen storage disease (GSD) type Ib. METHOD As part of a collaborative European Study on GSD type I, a retrospective registry was established in 12 European countries that included all patients with GSD-I who were known at the centers and were born from 1960 to 1995. Of a total of 288 patients with GSD-I, 57 who had GSD-Ib form the basis of this study. RESULTS Neutropenia (defined as an absolute neutrophil count <1 x 10(9)/L) was found in 54 patients. In 64% of the patients neutropenia was documented before the age of 1 year, but in 18% of the patients neutropenia was first noted between the ages of 6 and 9 years. Neutropenia was persistent in 5 patients and intermittent without any clear cyclical course in 45. Neutrophil function was investigated in 18 patients with neutropenia and was abnormal in all. Perioral infections were reported in 37 patients, perianal infections in 27 patients, and protracted diarrhea in 23 patients. Findings on colonoscopy and radiologic studies in 10 of 20 patients suspected to have IBD were abnormal in all. All patients with IBD, perioral infections, and perianal infections had neutropenia. CONCLUSIONS Intermittent severe neutropenia is frequently found in patients with GSD-Ib. The study also indicates that IBD in GSD-Ib is underdiagnosed; up to 77% of the patients studied had evidence of IBD, all of whom had neutropenia. IBD was not detected in those with normal neutrophil counts. These findings support the notion that neutropenia and/or neutrophil dysfunction in GSD-Ib and IBD are causally related.

Abstract
Neutrophils from patients suffering from glycogen storage disease type Ib (GSD-Ib) show several defects. one of which is a decreased rate of glucose utilization. In this study, we established experimental conditions to show the stimulation of the neutrophil respiratory burst by extracellular glucose. With phorbol-myristate-acetate as stimulus of the burst, the activity of the NADPH oxidase in GSD-Ib neutrophils hardly increased on addition of glucose. In control and GSD-type Ia neutrophils, a clear increase was observed. The lack of response to extracellular glucose in GSD-Ib neutrophils is correlated with the inability to raise intracellular glucose-6-P levels on glucose addition, thereby limiting the activity of the generation of NADPH in the hexose-monophosphate shunt. Our study shows the usefulness of this test for the diagnosis of neutrophil function abnormality in GSD-Ib patients.

Abstract
Decreased 2-deoxyglucose (2-DOG) uptake is well described in the neutrophils of patients with glycogen storage disease type 1b (GSD 1b). We report a patient with GSD 1b who presented with a normal antenatal and perinatal 2-deoxyglucose uptake that showed a slow regression during the first months of life. These indicate limitations of 2-deoxyglucose uptake in the diagnosis of GSD 1b. While it appears that low uptake rate below 0.25 nmol/min in 10(6) cells is of significance, normal uptake does not rule out the presence of the disease. It seems that antenatal diagnosis of GSD 1b cannot be made by measurement of 2-deoxyglucose uptake in the fetal neutrophils.

Abstract
Patients with glycogen storage disease (GSD) 1b suffer from recurrent bacterial infections related to neutropenia and impairment of neutrophil functions. One of these functions is the oxidative burst activity which is initiated by NADPH oxidase and depends on the availability of glucose. This activity was markedly reduced in the patient's intact neutrophils when either N-formyl-methionyl-leucyl-phenylalanine (fMLP), or phorbol myristate acetate were used as stimulants. In disrupted GSD 1b polymorphonuclear leucocytes (PMNs), in the presence of exogenous NADPH, this activity was within the normal range. Degranulation, which is calcium dependent but glucose independent, was not significantly different in neutrophils from the patients as compared to controls. Resting cytosolic calcium concentration was indistinguishable from controls. Activation with 10(-7) M fMLP, in the presence or absence of glucose, triggered a prompt and rapid elevation of cytosolic calcium both in the control and the patients' cells. We have previously shown that hexose monophosphate (HMP) shunt activity and glycolytic rate were found to be lower by 70% in intact PMN cells of the patients compared with controls. These activities were normal in disrupted neutrophils. The uptake of the non-metabolized glucose analogues 2-deoxyglucose (2-DOG) and 3-O-Methylglucose (3-OMG) into PMN of GSD 1b patients was studied. 2-DOG is phosphorylated within the cells, thus its uptake rate reflects hexose transport at low concentrations, as long as phosphorylation is not rate limiting. Under those conditions (5 microM 2-DOG) transport was found to be similar to controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A summary review of leukocyte function in 42 published cases of glycogen storage disease Ib is presented. Polymorphonuclear and monocyte dysfunctions were evidenced in the majority of cases, whereas lymphocytes appeared to be unaffected. Phagocyte dysfunctions comprised in vivo mobilization and motility, in vitro random and directed migration, and one or several component functions of the "metabolic" ("respiratory") burst. On the basis of the available data it is impossible to know whether a primary functional deficit of the glucose 6-phosphate transport protein of the microsomal glucose 6-phosphatase system, as demonstrated in liver, also exists in these phagocytic cells and is responsible for this dysfunction.

Abstract
Patients with glycogen storage disease (GSD) type 1b, in contrast to patients with GSD 1a, are susceptible to recurrent bacterial infections suggesting defective phagocytic function. We have demonstrated a selective defect in respiratory burst activity but not in degranulation by phagocytic cells in GSD 1b but not in GSD 1a. The respiratory burst abnormality in phagocytic cells from GSD 1b patients was associated with impaired calcium mobilization, whereas these processes were normal in GSD 1a patients. Therefore, the alteration in calcium mobilization was an indication of a signalling defect in phagocytic cells from GSD 1b. However, calcium mobilization was normal in lymphocytes, indicating that defective calcium mobilization was not a global finding in circulating leukocytes, but was specific to phagocytic cells. Calcium mobilization in response to ionomycin was reduced suggesting decreased calcium stores in GSD 1b neutrophils. Therefore, altered phagocytic cell function in GSD 1b patients appears to be associated with diminished calcium mobilization and defective calcium stores. This defective calcium signalling was associated with a selective defect in respiratory burst activity but not degranulation.

Abstract
Two children with glycogen storage disease type Ib associated with numerous recurrent bacterial infections as a result of neutropenia and neutrophil dysfunction were treated with recombinant human granulocyte colony-stimulating factor (G-CSF). One of the two patients was previously treated with recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF); therapy had to be discontinued because of severe local side effects. Both colony-stimulating factors at dosages of 3 and 8 micrograms/kg/per day, respectively, increased the average neutrophil counts from less than 300 cells/microliters to more than 1200 cells/microliters. Two subpopulations of neutrophils could be identified by their capacity to produce H2O2: one subpopulation generated H2O2 normally and a second was defective in H2O2 production. The doses of G-CSF effectively enhanced and maintained that subpopulation of neutrophils which produced normal amounts of H2O2. Moreover, these colony-stimulating factor-induced neutrophils demonstrated effective phagocytosis of zymosan particles and killing of staphylococci. Chemotaxis was decreased and could not be normalized by treatment with G-CSF. We conclude that maintenance treatment with G-CSF improved the quality of life in both patients: The number and severity of bacterial infections decreased markedly during treatment. Long-term treatment with G-CSF (12 and 10 months, respectively) was well tolerated, and no adverse clinical events were observed.

Abstract
Neutropenia, neutrophil dysfunction, and recurrent infections are important manifestations of glycogen storage disease type Ib. We report here a child who has had adequate metabolic control, but developed brain abscess, an infection not previously described in this disease. This case provides further evidence that the neutrophil anomaly is related to the basic enzyme defect, not secondary to the metabolic derangement.

Abstract
Two children with glycogen storage disease type 1B developed chronic inflammatory bowel disease. The first, a 7-year-old boy, had ileitis and later developed perianal disease. The second developed colitis by the age of 9 years; in both the features were consistent with Crohn disease. The children had neutropenia and neutrophil mobility defects characteristic of GSD-1B. It is suggested that these neutrophil abnormalities are important in the pathogenesis of the bowel inflammation.

Abstract
Patients with glycogen storage disease (GSD) type 1b (1b), in contrast to patients with GSD type 1a (1a), are susceptible to recurrent bacterial infections suggesting an impairment in their immune system. In this study, phagocytic cell (neutrophil and monocyte) respiratory burst activity, as measured by superoxide anion generation, oxygen consumption, and hexose monophosphate shunt activity, was markedly reduced in both neutrophils and monocytes from GSD 1b patients as compared with either GSD 1a patients or healthy adult control cells. Degranulation, unlike respiratory burst activity, was not significantly different in neutrophils from GSD 1b patients as compared with controls. Both neutrophils and monocytes from GSD 1b patients showed decreased ability to elevate cytosolic calcium in response to the chemotactic peptide f-Met-Leu-Phe. In addition, calcium mobilization in response to ionomycin was also attenuated suggesting decreased calcium stores. Thus, reduced phagocytic cell function in GSD 1b is associated with diminished calcium mobilization and defective calcium stores. Defective calcium signaling is associated with a selective defect in respiratory burst activity but not degranulation.
