Cystic fibrosis (CF) is the most common lethal autosomal recessive disease in Caucasians, but rare in Asians. The mutations of cystic fibrosis transmembrane conductance regulator (CFTR) gene are responsible for CF. To date, less than 5 cases of CF have been reported and a few of them diagnosed based on the genotype of the CFTR gene in Korea. We encountered a 4-month-old Korean infant with CF and the diagnosis was confirmed by CFTR gene mutation analysis. The patient underwent surgical operation, due to meconium ileus at birth. He suffered by recurrent respiratory infections, failure to thrive, fatty liver with hepatomegaly, and cholestasis. The mutations of the CFTR gene were identified in the patient and his parents. The patient was a compound heterozygote with a nonsense mutation of c.263T>G, resulting in an amino acid change of p.Leu88X in exon 3. It was previously described in a Korean patient with CF. The other is a novel mutation; c.2089-2090insA mutation (p.Arg697LysfsX33) in exon 13. The mutation c.263T>G was inherited from his father, and the c.2089-2090insA mutation from his mother. Respiratory infection was recovered by supportive care, and cholestasis was improved slowly with sufficient feeding and supplementation of pancreatic exocrine enzymes. He is 19- month old now and shows catch-up growth. We report a novel CFTR mutation in a Korean infant with CF.

Recent studies have suggested that milk and certain dairy food components have the potential to protect against cardiovascular disease. In order to determine whether the addition of milk-derived phospholipids to the diet results in an improvement in metabolic and cardiovascular risk factors, we studied four groups (n=10) of C57BL/6 mice that were fed: (1) a normal non-purified diet (N); (2) the normal non-purified diet supplemented with phospholipid-rich dairy milk extract (PLRDME, 2.5% by wt) (NPL); (3) a high-fat semi-purified diet (HF) containing 21% butterfat+0.15% cholesterol by wt; or (4) HF supplemented with 2.5% by wt PLRDME (HFPL). Dietary PLRDME supplementation did not have a significant effect on metabolic parameters in mice fed the N diet. In contrast, in high-fat fed mice, PLRDME caused a significant decrease in: (a) liver wt (1.57+/-0.06 g vs. 1.20+/-0.04 g, P<0.001), (b) total liver lipid (255+/-22 mg vs. 127+/-13 mg, P<0.001, (c) liver triglyceride (TG) and total cholesterol (TC) 236+/-25 micromol/g vs. 130+/-8 micromol/g (P<0.01), 40+/-7 micromol/g vs. 21+/-2 micromol/g (P<0.05), respectively); and serum lipids (TG: 1.4+/-0.1 mmol/L vs. 1.1+/-0.1 mmol/L, P=0.01; TC: 4.6+/-0.2 mmol/L vs. 3.6+/-0.2 mmol/L, P<0.001; and PL: 3.3+/-0.1 mmol/L vs. 2.6+/-0.1 mmol/L, P<0.01). These data indicate that dietary PLRDME has a beneficial effect on hepatomegaly, hepatic steatosis and elevated serum lipid levels in mice fed a high-fat diet, providing evidence that PLRDME might be of therapeutic value in human subjects as a hepatoprotective or cardioprotective nutraceutical.

Lysosomal acid lipase (LAL) deficiency results in Wolman disease and cholesteryl ester storage disease (CESD), a more benign form. CESD is a recessive disorder characterized by hypercholesterolaemia, hypertriglyceridaemia, low blood HDL and variable phenotype, while hepatomegaly is usually evident during childhood or adolescence. An 11-year-old girl was referred to our department for combined hyperlipidaemia (total cholesterol 323, triglycerides 259 mg/dl). All family members had normal lipid profile and liver function tests. At 8 years she was admitted for acute Epstein-Barr virus infection, with hepatosplenomegaly and elevation of liver enzymes. Liver-spleen enlargement resolved, but serum alanine aminotransferase and aspartate aminotransferase were persistently twice the upper limits, with other liver function tests within the normal range. Ultrasonography showed normal liver and spleen size and minimal hepatic steatosis. Infectious, autoimmune and metabolic causes of elevated liver enzymes were ruled out, including glycogen storage disease. Dysbetalipoproteinaemia was also ruled out (ApoE phenotype: E3E3). In the following 2 years the girl was symptom-free, BMI was at the 50th-75th centile for age and lipid profile was unchanged despite a low-fat diet. At 13 years of age, low acid lipase activity was demonstrated in leukocytes (10 nmol/h/ per mg protein, normal 140-380) and cultured skin fibroblasts (181 nmol/h per mg protein, normal 1100-2400), leading to diagnosis of CESD. CESD usually progresses to hepatic fibrosis, with high risk of premature atherosclerosis. CESD prevalence may be underestimated in the general population. The diagnosis may be considered in all subjects with atypical combined hyperlipidaemia (usually dominant in transmission or related to metabolic syndrome) and atypical 'fatty liver disease', in the absence of overweight.

Propofol is a widely used rapidly acting sedating or hypnotic agent in the intensive care setting. It is generally considered safe in both pediatric and adult patients and has been used frequently in cases of refractory status epilepticus. The formulation of propofol is highly lipophilic to facilitate central nervous system penetration and has a high fat content, and prolonged infusions have been known to cause both extrahepatic complications and hepatomegaly secondary to fatty liver. Whereas extrahepatic manifestations of prolonged propofol infusions have been well reported in non-neurologic intensive care patients, cases of pathologically confirmed fatty liver in patients with status epilepticus are relatively few. Furthermore, these cases of hepatomegaly and fatty liver have been also in the context of concomitant extrahepatic side effects. We report on a pediatric patient with refractory status epilepticus treated with a prolonged propofol infusion who developed isolated pathologically confirmed fatty liver without the usually reported extrahepatic manifestations.

Adiponectin is an insulin-sensitizing adipokine possessing multiple beneficial effects on obesity-related medical complications. This adipokine is secreted from adipocytes into the circulation as three oligomeric isoforms, including trimer, hexamer and the high molecular weight (HMW) oligomeric complex. Each oligomeric isoform of adiponectin possesses distinct biological properties and activates different signaling pathways in various target tissues. The hepato-protective activities have been demonstrated by many clinical and experimental studies. The decreased level of serum adiponectin represents an independent risk factor for nonalcoholic fatty liver disease (NAFLD) and liver dysfunctions in humans. In animals, elevation of circulating adiponectin by either pharmacological or genetic approaches leads to a significant alleviation of hepatomegaly, steatosis and necro-inflammation associated with various liver diseases. In adiponectin knockout mice, there is a pre-existing condition of hepatic steatosis and mitochondria dysfunction, which might contribute to the increased vulnerabilities of these mice to the secondary liver injuries induced by obesity and other conditions. This review aims to summarize recent advances on delineation of the structural, molecular and cellular mechanisms underlying the hepato-protective properties of adiponectin.

Krill oil (KO) is rich in n-3 fatty acids that are present in phospholipids rather than in triglycerides. In the present study, we investigated the effects of dietary KO on cardiometabolic risk factors in male C57BL/6 mice fed a high-fat diet. Mice (n = 6-10 per group) were fed for 8 weeks either: (1) a nonpurified chow diet (N); (2) a high-fat semipurified diet containing 21 wt % buttermilk + 0.15 wt % cholesterol (HF); (3) HF supplemented with 1.25 wt % KO (HFKO1.25); (4) HF with 2.5 wt % KO (HFKO2.5); or (5) HF with 5 wt % KO (HFKO5.0). Dietary KO supplementation caused a significant reduction in liver wt (i.e., hepatomegaly) and total liver fat (i.e., hepatic steatosis), due to a dose-dependent reduction in hepatic triglyceride (mean +/- SEM: 35 +/- 6, 47 +/- 4, and 51 +/- 5% for HFKO1.25, -2.5, and -5.0 vs HF, respectively, P < 0.001) and cholesterol (55 +/- 5, 66 +/- 3, and 71 +/- 3%, P < 0.001). Serum cholesterol levels were reduced by 20 +/- 3, 29 +/- 4, and 29 +/- 5%, and blood glucose was reduced by 36 +/- 5, 34 +/- 6, and 42 +/- 6%, respectively. Serum adiponectin was increased in KO-fed animals (HF vs HFKO5.0: 5.0 +/- 0.2 vs 7.5 +/- 0.6 microg/mL, P < 0.01). These results demonstrate that dietary KO is effective in improving metabolic parameters in mice fed a high-fat diet, suggesting that KO may be of therapeutic value in patients with the metabolic syndrome and/or nonalcoholic fatty liver disease.

The age-induced decline in the body's ability to fight disease is exacerbated by obesity and metabolic disease. Using a mouse model of diet-induced obesity, the combined challenge of a high-fat diet and age on liver morphology and biochemistry was characterized, while evaluating the potential of 15 min per day of high frequency (90 Hz), extremely low-magnitude (0.2 G) mechanical signals (LMMS) to suppress lipid accumulation in the liver. Following a 36-week protocol (animals 43 weeks of age), suppression of hepatomegaly and steatosis was reflected by a 29% lower liver mass in LMMS animals as compared with controls. Average triglyceride content was 101.7+/-19.4 microg mg(-1) tissue in the livers of high-fat diet control (HFD) animals, whereas HFD+LMMS animals realized a 27% reduction to 73.8+/-22.8 microg mg(-1) tissue. In HFD+LMMS animals, liver free fatty acids were also reduced to 0.026+/-0.009 microEq mg(-1) tissue from 0.035+/-0.005 microEq mg(-1) tissue in HFD. Moderate to severe micro- and macrovesicular steatosis in HFD was contrasted to a 49% reduction in area covered by the vacuoles of at least 15 microm(2) in size in HFD+LMMS animals. These data provide preliminary evidence of the ability of LMMS to attenuate the progression of fatty liver disease, most likely achieved indirectly by suppressing adipogenesis and thus the total adipose burden through life, thereby reducing a downstream challenge to liver morphology and function.

We focused on over-dose insulin (250 IU/kg i.p.) induced gastric ulcers and then on other disturbances that were concomitantly induced in rats, seizures (eventually fatal), severely damaged neurons in cerebral cortex and hippocampus, hepatomegaly, fatty liver, increased AST, ALT and amylase serum values, breakdown of liver glycogen with profound hypoglycemia and calcification development. Calcium deposits were present in the blood vessel walls, hepatocytes surrounding blood vessels and sometimes even in parenchyma of the liver mainly as linear and only occasionally as granular accumulation. As an antidote after insulin, we applied the stable gastric pentadecapeptide BPC 157 (10 microg/kg) given (i) intraperitoneally or (ii) intragastrically immediately after insulin. Controls received simultaneously an equivolume of saline (5 ml/kg). Those rats that survived till the 180 minutes after over-dose application were further assessed. Interestingly, pentadecapeptide BPC 157, as an antiulcer peptide, may besides stomach ulcer consistently counteract all insulin disturbances and fatal outcome. BPC 157 rats showed no fatal outcome, they were mostly without hypoglycemic seizures with apparently higher blood glucose levels (glycogen was still present in hepatocytes), less liver pathology (i.e., normal liver weight, less fatty liver), decreased ALT, AST and amylase serum values, markedly less damaged neurons in brain and they only occasionally had small gastric lesions. BPC 157 rats exhibited mostly only dot-like calcium presentation. In conclusion, the success of BPC 157 therapy may indicate a likely role of BPC 157 in insulin controlling and BPC 157 may influence one or more causative process(es) after excessive insulin application.

Type Ia Glycogen storage disease is an autosomal recessive hepatic metabolic disease due to a lack of glucose-6-phosphatase (G-6-Pase) activity presenting with growth retardation, lactic acidosis, fasting hypoglycemia with hypoinsulinemia, hyperuricemia, hepatomegaly, and hepatic adenoma with a risk of malignancy. The gene that encodes G-6-Pase was mapped to 17q21. There are some genotype-phenotype correlations. We report a case with delF327 mutation which is devoid of G-6-Pase activity; however clinical presentation in this case differs somewhat. Although correction of hypoglycemia and lactic acidosis with nocturnal intragastric feeding and uncooked starch therapy improves growth failure, mean height of the patients is often less than the target. Normal height and obesity in this case with hepatic steatosis and low hepatic glycogen storage requires clinical reevaluation since there are some overlapping phenotypes between type Ia GSD and metabolic syndrome. The phenomenon may be related to insulin resistance as a consequence of early aggressive nutrition therapy with frequent low glycemic index meals.

The effects of soybean-derived phospholipid, PIPS NAGASE(TM) (PIPS), on obesity-induced diseases were studied in obese rats. Dietary PIPS alleviated hepatomegaly and fatty liver in the rats. These effects were attributable to reduced lipogenesis and enhanced lipolysis in the liver. The results suggest that PIPS can be useful as a dietary component that would reduce the risk of lifestyle-related diseases.
