[A case of liver abscess with meningitis and endophthalmitis: invasive liver abscess syndrome].

A woman in her 70s was hospitalized and was diagnosed with liver abscess and managed with antibiotics in a previous hospital. However, she experienced altered consciousness and neck stiffness during treatment. She was then referred to our hospital. On investigation, we found that she had meningitis and right endophthalmitis concurrent with a liver abscess. Klebsiella pneumoniae was detected from both cultures of the liver abscess and effusion from the cornea. A string test showed a positive result. Therefore, she was diagnosed with invasive liver abscess syndrome. Although she recovered from the liver abscess and meningitis through empiric antibiotic treatment, her right eye required ophthalmectomy. In cases where a liver abscess presents with extrahepatic complications, such as meningitis and endophthalmitis, the possibility of invasive liver abscess syndrome should be considered, which is caused by a hypervirulent K. pneumoniae.

Seropositivity and Titers of Anti-Smooth Muscle Actin Antibody Are Associated with Relapse of Type 1 Autoimmune Hepatitis.

BACKGROUND It is important to avoid relapse in autoimmune hepatitis (AIH) because repeated multiple relapses have been associated with a worse prognosis. However, risk factors for relapse before initiation of treatment are not fully understood. The aim of this study was to find predictive markers for relapse of type 1 AIH. MATERIAL AND METHODS We reviewed the records of 53 patients diagnosed with type 1 AIH based on the revised scoring system proposed by the International Autoimmune Hepatitis Group (IAIHG) between 2009 and 2014 at 4 hospitals belonging to the Saga Study Group of Liver Diseases (SASLD). We analyzed the differences in background characteristics between patients with or without relapse. RESULTS All patients achieved remission after treatment, and 9 (17%) subsequently relapsed. The relapsed patients were significantly younger and had a higher positive rate of anti-smooth muscle antibody (ASMA) than the non-relapsed patients (100% vs. 25%, P=0.0012). Moreover, relapse rate increased with titer of ASMA, while titer of antinuclear antibody was not associated with relapse rate. CONCLUSIONS ASMA is a useful predictive marker for relapse of type 1 AIH during or after withdrawal of medical therapy. More careful attention should be paid to immunosuppressive therapy in patients with high titers of ASMA.

Sarcopenia is a risk factor for the recurrence of hepatocellular carcinoma after curative treatment.

BACKGROUND AND AIM: Sarcopenia, initially proposed as decreased of muscle mass and strength, is associated with aging and malignant diseases. The aim of the present study was to determine whether there is a correlation between sarcopenia and the recurrence of hepatocellular carcinoma (HCC) after curative treatment. METHODS: We conducted a retrospective analysis of consecutive naive patients with HCC who underwent curative resection or radiofrequency ablation. To eliminate the influence of cause or the severity of liver damage, subjects were limited to those with HCC with hepatitis C-related cirrhosis and Child-Pugh class A liver function. Patients were assessed using computed tomographic measurement of muscle mass at the level of the third lumbar (L3) vertebrae, the L3 skeletal muscle index (L3 SMI). Sarcopenia was defined by using previously published, sex-specific cut-off value. RESULTS: Sarcopenia was present in 61 of 92 patients. Patients' median age was 71.5 years (range, 47-84), and the baseline characteristics of patients were comparable between patients with and without sarcopenia except for sex, serum albumin level, prothrombin time, diabetes mellitus and body mass index. Recurrence rates at 1, 3 and 5 years were 39.1%,77.1%,81.7% for patients with sarcopenia and 23.5%,59.5% and 75.7% for patients without sarcopenia, respectively (P = 0.03). Multivariate Cox analysis revealed that sarcopenia and preoperative α-fetoprotein of more than 40 ng/mL were significant independent factors for recurrence. CONCLUSION: Sarcopenia is a risk factor for recurrence in patients with HCC who were treated with curative treatment.

Efficacy of ezetimibe for reducing serum low-density lipoprotein cholesterol levels resistant to lifestyle intervention in patients with non-alcoholic fatty liver disease.

AIM: To investigate the efficacy of ezetimibe and lifestyle intervention for treating patients with non-alcoholic fatty liver disease (NAFLD) and residual dyslipidemia via a combination of ezetimibe and lifestyle intervention. METHODS: Patients with NAFLD with residual dyslipidemia after a 6-month lifestyle intervention program were included. After completion of the 6-month program, the patients received p.o. administration of ezetimibe at 10 mg/day, in addition to lifestyle intervention, for 6 months. RESULTS: Of the 59 patients with NAFLD who had participated in the 6-month lifestyle intervention program between 2007 and 2012, 21 with residual dyslipidemia (10 males and 11 females) were enrolled. Median age was 58 years (range, 27-75), median bodyweight was 63.0 kg (range, 39.4-109.0), median body mass index was 25.4 kg/m2 (range, 18.2-37.1), median alanine aminotransferase was 23 IU/L (14-73), median high-density lipoprotein (HDL) was 58 mg/dL (range, 37-93), median triglycerides (TG) was 105 mg/dL (range, 42-216) and median low-density lipoprotein (LDL) was 153 (66-209) mg/dL. After 6 months of treatment with ezetimibe, serum LDL levels were improved in 15 of 20 (75%) patients (P = 0.0015), while no improvements were observed in the remaining five patient (25%). Ezetimibe was discontinued in one patient who developed skin rash. CONCLUSION: Ezetimibe is effective for treating residual dyslipidemia after lifestyle intervention in patients with NAFLD.

[A case of multiple liver abscesses associated with Streptococcus salivarius in a patient with chronic periodontitis].

Streptococcus salivarius is an oral commensal bacterium that rarely causes disease in humans. Here, we report a case of liver abscess associated with S. salivarius in a 41-year-old woman who presented with continuous abdominal discomfort, fatigue, and fever. She was diagnosed with multiple liver abscesses; she underwent percutaneous transhepatic abscess drainage. Thereafter, S. salivarius was isolated in all bacterial cultures of the drained abscesses, and it was sensitive to penicillins. She made a good recovery after treatment. In the absence of an infective source other than chronic periodontitis, the cause of liver abscesses was attributed to oral S. salivarius. S. salivarius is a normal oral commensal, and oral commensals must be considered if the infective origin of liver abscess cannot be determined.

Evaluation narcotic analgesic use and survival time in terminal stage liver diseases compared with lung cancer: a retrospective chart review.

Hepatocellular carcinoma (HCC) and liver cirrhosis are fatal diseases. This study aimed to investigate survival time and palliative care in terminal HCC and/or liver cirrhosis compared with lung cancer. Between January 2004 and December 2010, we enrolled 116 patients with terminal cirrhosis and/or HCC or lung cancer admitted to a municipal hospital in Japan; 48 had liver cirrhosis, 35 HCC and 33 lung cancer. By retrospective chart review, we evaluated: (i) rate of usage of narcotic analgesics and (ii) survival time from onset of coma (Glasgow Coma Scale less than 8). Time between coma and death was significantly shorter in the liver disease patients (cirrhosis and/or HCC: 7.0 h) than in lung cancer (44.0 h, p = 0.045). Total bilirubin was higher in HCC compared with cirrhosis (p<0.01). Rate of usage of narcotic analgesics was higher in lung cancer (20/33: 60.6%) than in liver disease (17/83: 20.5%, p<0.01); analgesics were used more frequently in HCC than in liver cirrhosis (p<0.01). These results suggest that liver cirrhosis and HCC patients do not always require palliative care and that survival time from onset of coma due to liver disease was not prolonged compared with lung cancer.

Gemcitabine plus nab-paclitaxel in older patients with metastatic pancreatic cancer: A post-hoc analysis of the real-world data of a multicenter study (the NAPOLEON study).

OBJECTIVES: This study aimed to examine the efficacy and safety of gemcitabine plus nab-paclitaxel (GnP) in older patients with metastatic pancreatic cancer (MPC), especially those ≥75 years old. MATERIALS AND METHODS: This study retrospectively enrolled 153 patients with MPC who received GnP as first-line chemotherapy. Patients ≥75 years old were allocated to the older group, and those <75 years old were assigned to the non-older group. We compared safety, antitumor efficacy, and survival between the two groups. In the older group, prognostic indicators of survival were also assessed. RESULTS: The pretreatment characteristics of the two groups were not significantly different excluding age, history of malignancy, and C-reactive protein levels. The initial dose and relative dose intensities of GnP were significantly lower in the older group. There were no significant differences in the adverse event and antitumor response rates between the two groups. Median progression-free survival and overall survival were 5.5 and 12.0 months, respectively, in the older group, versus 6.0 and 11.1 months, respectively, in the non-older group. In the older group, a Geriatric Nutrition Risk Index (GNRI) of less than 86 was associated with poor prognosis. CONCLUSION: GnP exhibited acceptable efficacy and safety in patients ≥75 years old with MPC. GNRI might be helpful for identifying older individuals at higher risk of unfavorable outcomes.

Evaluation of acoustic radiation force impulse elastography for fibrosis staging of chronic liver disease: a pilot study.

BACKGROUND: Acoustic radiation force impulse (ARFI) is a new technology integrated into conventional B-mode ultrasonography. ARFI is used to evaluate tissue stiffness in several organs, but this method has not been applied for liver fibrosis. AIM: The aim of this study was to determine whether ARFI elastography is useful for the evaluation of liver fibrosis. METHODS: This study enrolled 55 consecutive patients with chronic liver disease who underwent a liver biopsy for histological assessment of liver fibrosis by the Metavir scoring system. Liver stiffness of the 55 patients and 25 healthy volunteers was evaluated by ARFI elastography and was expressed as the shear wave velocity. Cut-off values were determined using receiver-operating characteristic (ROC) curves. RESULTS: Histological liver fibrosis was evaluated by Metavir scoring; F0: six cases, F1: 14 cases, F2: nine cases, F3: nine cases and F4: 17 cases. Liver stiffness determined by ARFI elastography was correlated with histological liver fibrosis (P<0.0001). The areas under the ROC curves were 0.94 (95% confidence intervals, 0.87-0.99) for F2-F4, 0.94 (0.88-0.99) for F3-F4 and 0.96 (0.91-1.01) for F4. The cut-off values of the shear wave velocity were as follows: >1.34 m/s for F2-F4 (sensitivity 91.4%, specificity 80%); >1.44 m/s for F3-F4 (sensitivity 96.2%, specificity 79.3%); and >1.80 m/s for F4 (sensitivity 94.1%, specificity 86.8%). CONCLUSIONS: Ultrasonic ARFI elastography is a novel, non-invasive and reliable method for the assessment of liver fibrosis in patients with chronic liver disease.

Assessment of tumor volume and density as a measure of the response of advanced hepatocellular carcinoma to sorafenib: Application of automated measurements on computed tomography scans.

BACKGROUND AND AIM: To better predict patient survival, we used automated tumor volume and density measurements to make an objective radiological assessment of the response of advanced hepatocellular carcinoma (HCC) to treatment with sorafenib. METHODS: Patients treated with sorafenib were identified retrospectively. Those who were diagnosed with Child-Pugh class A liver function, Barcelona-Clinic Liver Cancer stage C, and Eastern Cooperative Oncology Group performance status grade 0/1 were enrolled (n = 22). Reviews of contrast-enhanced computed tomography images were supported by the automated measurement of lesions using computer software. Treatment responses were assessed using volume and density criteria. Kaplan-Meier methods and multivariate Cox regression analysis were used to evaluate treatment responses and identify the most significant prognostic factors for overall survival (OS). RESULTS: After patients were dichotomized according to volume and density criteria, the median OS for those with an objective response (OR) (complete response + partial response) was 20.4 months and that for those with a non-OR (stable disease + progressive disease) was 9.3 months (P = 0.009). The best multivariate regression model for survival identified volume and density criteria (OR or non-OR) as a significant variable, along with baseline alpha-fetoprotein levels (log-rank test, P = 0.01). No other conventional criteria were identified as significant. CONCLUSIONS: Tumor volume and density assessment using automated lesion measurements may be an objective method of evaluating responses of advanced HCC to treatment with sorafenib.

Hepatitis C virus infection enhances insulin resistance induced by visceral fat accumulation.

BACKGROUND/AIMS: To clarify the impact of visceral obesity on hepatitis C virus (HCV)-infected patients, we examined the relationship between insulin resistance development and visceral fat accumulation. METHODS: We analyzed 87 HCV-infected patients with mild fibrosis (stage 1 or 2) in comparison with 125 sex- and age-matched patients with non-alcoholic fatty liver disease (NAFLD). The degree of visceral fat area (VFA; cm(2)) at the umbilical level was measured by abdominal computed tomography and divided into two grades: no visceral obesity, VFA<100 and visceral obesity, VFA>/=100. Insulin resistance was evaluated by homeostasis model assessment of insulin resistance (HOMA-IR) and the quantitative insulin sensitivity check index (QUICKI). Pancreatic beta-cell function was evaluated by homeostasis model assessment of beta-cell function (HOMA-beta). Serum soluble tumour necrosis factor (TNF)-receptors 1 and 2 and adiponectin were measured. RESULTS: Insulin resistance evaluated by HOMA-IR and QUICKI was correlated with visceral fat accumulation, and was higher in HCV patients than in NAFLD patients with visceral obesity. HOMA-beta was higher in HCV patients than in NAFLD patients for each VFA grade. Serum-soluble TNF-receptors 1 and 2 were higher in HCV patients than in NAFLD patients with visceral obesity. CONCLUSIONS: Hepatitis C virus infection is a risk factor for development of insulin resistance, particularly in patients with visceral obesity.

Waist circumference correlates with hepatic fat accumulation in male Japanese patients with non-alcoholic fatty liver disease, but not in females.

BACKGROUND AND AIM: Abdominal obesity, a component of metabolic syndrome, is a major risk factor for non-alcoholic fatty liver disease (NAFLD). In recent worldwide definitions of metabolic syndrome, waist measurement has been proposed as a simple and useful estimate of abdominal obesity, taking into account gender differences in waist circumference. The present cross-sectional study investigated the correlation of hepatic fat accumulation and waist circumference in Japanese NAFLD patients to determine if there are gender differences in this relationship. METHODS: Consecutive patients (n = 2111) who had at least one of two criteria for liver disease (alanine aminotransferase [ALT] level >30 IU/mL and aspartate aminotransferase [AST]/ALT ratio <1) underwent abdominal ultrasonography. Patients positive for hepatitis B virus, hepatitis C virus or autoimmune antibodies and whose alcohol intake was >20 g/day were excluded. Patients with NAFLD underwent abdominal computed tomography. Hepatic fat accumulation was estimated by liver/spleen attenuation ratio (L/S ratio) and visceral adipose accumulation was measured as visceral fat area (VFA) at the umbilical level. RESULTS: Of the 221 NAFLD patients, 103 were females. In males, the relationship between L/S ratio and waist circumference was negative (r =-0.356, P < 0.01), and there was no correlation in the female group. The relationship between L/S ratio and VFA was negative in both groups (males: r = -0.269, P < 0.01; females: r = -0.319, P < 0.01). Subcutaneous fat area/total fat area ratio at the umbilical level was larger in females than in males (P < 0.01). CONCLUSIONS: In NAFLD patients, waist measurement is more susceptible to gender differences than VFA.

A long-term survivor of undifferentiated carcinoma of the liver successfully treated with surgical treatments: A case report and literature review.

INTRODUCTION: Undifferentiated carcinoma of the liver is extremely rare. The biological characteristics and standard strategy for its treatment have not been established yet. PRESENTATION OF CASE: A 45-year-old man was admitted because of fever elevation and shivering. Abdominal computed tomography revealed a hypovascular cystic mass in segments 6 and 7 of the liver measuring 11.5 × 9.0 cm with ring enhancement and partial solid component. A diagnosis of liver abscess was made, and percutaneous transhepatic abscess drainage was performed. Reddish brown-colored pus showed no bacteria or amoebas. However, cytology demonstrated malignant cells. After additional examinations of magnetic resonance imaging and the positron emission tomography, extended posterior sectionectomy with cholecystectomy was performed. The excised specimen showed a solid and irregular tumor with extensive central necrosis. A pathological examination revealed diffuse proliferation of oval- and spindle-shaped malignant cells. Immunohistochemically, the malignant cells were diffusely positive for AE1/AE3 and vimentin and focally positive for granulocyte colony-stimulating factor and cytokeratin 19; however, hepatocyte-specific antigen, glypican 3, cytokeratin 7, and CD56 were negative. Therefore, a diagnosis of undifferentiated carcinoma of the liver was made. He has remained well without any recurrence for three years since the operation. DISCUSSION: Undifferentiated carcinoma of the liver might grow rapidly, resulting in necrosis with a cystic component. Therefore, it can be difficult to distinguish from liver abscess. CONCLUSION: This disease has markedly different clinical and biological features from common primary malignant tumor of the liver. However, if the tumor is a solitary mass, surgical resection might lead to a good prognosis.

Factors Associated with Post-Progression Survival in Patients with Advanced Hepatocellular Carcinoma Treated with Sorafenib.

Sorafenib exerts modest antitumor activity in patients with advanced hepatocellular carcinoma (HCC), and radiological progressive disease (rPD) does not always correspond to so-called clinical progressive disease (cPD). We evaluated 101 patients who initiated sorafenib treatment for HCC and assessed post-progression survival (PPS) using the Cox proportional hazards model. PPS was calculated from the date of the first rPD until the date of death or the last follow-up. Using Cox model analysis of the 76 patients who experienced first rPD, we identified the Child-Pugh class, Eastern Cooperative Oncology Group performance status, the best antitumor response during treatment (using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1) and α-fetoprotein levels as independent factors affecting PPS. When these factors were used to define scores ranging from zero to five with a cutoff value of two, PPS of patients who received best supportive care (BSC) after rPD was not statistically significantly different from that of patients who received post-rPD therapy with scores ≥2 (p = 0.220). In contrast, the PPS for the post-rPD therapy group was significantly longer compared with the BSC patients with scores <2 (p < 0.001). Patients who scored ≥2 at their first rPD were judged cPD and as candidates for BSC.

Granulomatous reaction in hepatic inflammatory angiomyolipoma after chemoembolization and spontaneous rupture.

A 77-year-old Japanese woman was transported to a nearby hospital due to sudden abdominal pain and transient loss of consciousness. Abdominal computed tomography (CT) suggested hemoperitoneum and hepatic nodule. She was conservatively treated. Contrast-enhanced CT two months later revealed an increased mass size, and the enhancement pattern suggested the possibility of hepatocellular carcinoma (HCC). Under a clinical diagnosis of HCC, transcatheter arterial chemoembolization (TACE) was performed. A subsequent imaging study revealed that most of the lipiodol used for the embolization was washed out. Therefore, surgical resection was performed. Histologically, the nodule contained numerous inflammatory cells including small lymphocytes, plasma cells and macrophages. Notably, epithelioid granulomatous features with multinucleated giant cells were observed in both the nodule and background liver. Some of the multinucleated giant cells contained oil lipid. Among the infiltrating inflammatory cells, spindle-shaped, histiocytoid or myoid tumor cells with eosinophilic cytoplasm were found. The tumor cells were positive for Melan A and HMB45. The nodule contained many IgG4-positive plasma cells; these were counted and found to number 72.6 cells/HPF (range: 61-80). The calculated IgG4:IgG ratio was 33.2%. The nodule was finally diagnosed as previously ruptured inflammatory angiomyolipoma modified by granulomatous reaction after TACE.

Impact of Body Weight Reduction via Diet and Exercise on the Anti-Viral Effects of Pegylated Interferon Plus Ribavirin in Chronic Hepatitis C Patients with Insulin Resistance: A Randomized Controlled Pilot Trial.

OBJECTIVE: Insulin resistance (IR) modifies the anti-viral effects of interferon (IFN) therapy in patients with chronic hepatitis C (CHC). This prospective study evaluated whether lifestyle interventions improve the anti-viral response to treatment with pegylated (PEG)-IFN plus ribavirin (RBV) in patients with CHC. METHODS: The study cohort consisted of 60 patients chronically infected with a high viral load of hepatitis C virus genotype 1b and a homeostasis model assessment of IR (HOMA-IR) value above 2. The patients were divided into two groups, an intervention group (n=26) and a control group (n=34). The patients in the intervention group were prescribed diet and exercise treatment for 3-6 months to reduce their body weight by ≥5% before starting treatment with PEG-IFN plus RBV. RESULTS: Diet and exercise significantly reduced the HOMA-IR values in the intervention group, from 3.4 to 2.5 (p=0.0009), especially among the 15 patients who achieved a body weight reduction of ≥5%. The viral disappearance rate at 12 weeks was significantly higher in the intervention group among the patients with a ≥5% weight reduction than in the control group (53.3% vs. 23.5%, p=0.01). However, the sustained viral response (SVR) rates were similar. CONCLUSION: Improvements in IR achieved through weight reduction via lifestyle interventions may enhance the early viral response to PEG-IFN plus RBV in patients with CHC. However, this intervention program has no effect on the SVR rate.

Low-dose rectal diclofenac for prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis: a randomized controlled trial.

BACKGROUND: Acute pancreatitis is a common complication of endoscopic retrograde cholangiopancreatography (ERCP). Rectal nonsteroidal anti-inflammatory drugs (specifically, 100 mg of diclofenac or indomethacin) have shown promising prophylactic activity in post-ERCP pancreatitis (PEP). However, the 100-mg dose is higher than that ordinarily used in Japan. METHODS: We performed a prospective randomized controlled study to evaluate the efficacy of low-dose rectal diclofenac for the prevention of PEP. Patients who were scheduled to undergo ERCP were randomized to receive a saline infusion either with 50 mg of rectal diclofenac (diclofenac group) or without (control group) 30 min before ERCP. The dose of diclofenac was reduced to 25 mg in patients weighing <50 kg. The primary outcome measure was the occurrence of PEP. RESULTS: Enrollment was terminated early because the planned interim analysis found a statistically significant intergroup difference in the occurrence of PEP. A total of 104 patients were eligible for this study; 51 patients received rectal diclofenac. Twelve patients (11.5%) developed PEP: 3.9% (2/51) in the diclofenac group and 18.9% (10/53) in the control group (p = 0.017). After ERCP, the incidence of hyperamylasemia was not significantly different between the two groups. Post-ERCP pain was significantly more frequent in the control group than in the diclofenac group (37.7 vs. 7.8%, respectively; p < 0.001). There were no adverse events related to diclofenac. CONCLUSIONS: Low-dose rectal diclofenac can prevent PEP.

Age-related fat deposition in multifidus muscle could be a marker for nonalcoholic fatty liver disease.

BACKGROUND: Although nonalcoholic fatty liver disease (NAFLD) is associated with visceral obesity, the relationship between visceral fat accumulation and skeletal muscle steatosis in patients with NAFLD has not been established. We evaluated: (1) the relationship between multifidus muscular tissue steatosis, visceral fat accumulation, and biochemical data in a cross-sectional study, and (2) the influence of weight reduction on multifidus muscular tissue steatosis in a longitudinal study. METHODS: Three hundred thirty-three NAFLD patients were enrolled. Hepatic steatosis, visceral fat area, and the multifidus muscle/subcutaneous fat attenuation ratio (MM/F ratio) were evaluated by computed tomography. To evaluate how weight reduction produced by diet and exercise affected the MM/F ratio, changes in the MM/F ratio were compared between weight reduction and non-weight reduction groups. RESULTS: There was a gender difference in MM/F ratios. The MM/F ratio was significantly correlated with age (male r = 0.613, P < 0.01; female r = 0.440, P < 0.01). The MM/F ratio was positively correlated with visceral fat area (male: r = 0.262, P < 0.01; female: r = 0.214, P < 0.01). A decrease in the MM/F ratio, concomitant with reduced visceral fat accumulation, led to alleviation of hepatic steatosis in 20 patients with weight reduction, but not in 22 patients without weight reduction. CONCLUSIONS: The MM/F ratio was closely related to aging and visceral fat accumulation. The MM/F ratio was improved by weight reduction, indicating that fat accumulation in the multifidus muscle evaluated by computed tomography might be a therapeutic indicator of NAFLD.

A pilot trial of body weight reduction for nonalcoholic fatty liver disease with a home-based lifestyle modification intervention delivered in collaboration with interdisciplinary medical staff.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a hepatic manifestation of the metabolic syndrome. The aim of this study was to evaluate a 6-month home-based lifestyle modification intervention delivered in collaboration with physicians, hygienists, registered dietitians, and nurses. METHODS: Outpatients with NAFLD diagnosed by abdominal ultrasonography were eligible for this study. Abdominal computed tomography (CT) scan evaluated liver fat deposition by the liver-spleen ratio (L/S ratio) and visceral fat accumulation as the visceral fat area (VFA; cm(2)). During the 6-month home-based lifestyle modification intervention, each patient was examined by physicians, nurses, hygienists, and registered dietitians, who provided individualized advice to the patients. Patients recorded their daily weight for self-control of weight with recommended diet and exercise regimens. RESULTS: Sixty-seven NAFLD patients were enrolled in this study and 22 patients (32.8%) completed the 6-month intervention. Nineteen of the 22 patients achieved significant improvements in body weight, body mass index (BMI), waist circumference, VFA, L/S ratio, and systolic blood pressure, with improved laboratory data. Overall, 39 patients withdrew from the intervention. The mean age of the patients who withdrew was 50.0 +/- 11.0 years, which was significantly younger than that of the patients who were followed up (60.1 +/- 10.1 years; P < 0.01). CONCLUSIONS: The reduction in body weight achieved by NAFLD patients during the 6-month intervention was associated with improved fat deposition and liver function. This intervention offers a practical approach for treating a large number of NAFLD patients with lifestyle modification therapy.
