Intensive methotrexate and cytarabine followed by high-dose chemotherapy with autologous stem-cell rescue in patients with newly diagnosed primary CNS lymphoma: an intent-to-treat analysis.

PURPOSE: To assess the safety and efficacy of intensive methotrexate-based chemotherapy followed by high-dose chemotherapy (HDT) with autologous stem-cell rescue in patients with newly diagnosed primary CNS lymphoma (PCNSL). PATIENTS AND METHODS: Twenty-eight patients received induction chemotherapy using high-dose systemic methotrexate (3.5 g/m2) and cytarabine (3 g/m2 daily for 2 days). Fourteen patients with chemosensitive disease evident on neuroimaging then received high-dose therapy using carmustine, etoposide, cytarabine, and melphalan with autologous stem-cell rescue. RESULTS: The objective response rate to the induction-phase chemotherapy was 57%, and median overall survival is not yet assessable, with a median follow-up time of 28 months. The overall median event-free survival time is 5.6 months for all patients and 9.3 months for 14 patients who underwent transplantation. Six of these 14 patients (43%) remained disease-free at last follow-up. Treatment was well tolerated; there was one transplantation-related death. Prospective neuropsychologic evaluations have revealed no evidence of treatment-related neurotoxicity. CONCLUSION: This treatment approach is feasible in patients with newly diagnosed PCNSL without evidence of significant related neurotoxicity. Although the transplantation results are similar to those achieved in patients with aggressive or poor-prognosis systemic lymphoma, the low response rate to induction chemotherapy and the significant number of patients who experienced relapse soon after HDT suggest that more aggressive induction chemotherapy may be warranted.

Liver regeneration is not altered in patients with nonalcoholic steatohepatitis (NASH) when compared to chronic hepatitis C infection with similar grade of inflammation

Fatty infiltration is associated with an increased incidence of complications and mortality after liver resection and transplantation. The aim of this study was to document the regenerative response in patients with hepatic steatosis and mild inflammatory activity (NASH) and to identify potential levels of impaired regeneration. Ki-67 immunostaining was similar in patients with NASH (ages 44.6 ± 15 years, labeling index, 0.4 ± 0.3%) when compared to patients with chronic hepatitis C infection (ages 50.7 ± 17 years, labeling index; 0.4 ± 0.7%). The labeling index was not increased in patients with a higher level of inflammation, a higher level of fibrosis, and a higher level of fat in either study group. In conclusion, liver regeneration is not altered in patients with nonalcoholic steatohepatitis, suggesting that the delayed postoperative liver failure seen in these patients may be related to another mechanism.

Correlation between changes in liver stiffness and preeclampsia as shown by transient elastography

Objective: The aim of this study was to evaluate the use of Fibroscan as a measure of liver transient elastography in women with preeclampsia and compare the results with a group of normotensive controls. Materials and Methods: In this prospective observational case-control study, women at 24–41 weeks gestation who were diagnosed with preeclampsia using standard criteria, between January 2012 and December 2013, were included. The Fibroscan test was performed by a hepatologist 1–7 days postpartum. A control group consisted of low-risk women with normal pregnancy outcomes. Results: Fibroscan results for fibrosis were significantly higher in the 32 preeclamptic women compared to the 16 normotensive women (mean 4.57 kPa vs. 3.66 kPa respectively, P = 0.01). There was no difference in liver steatosis between women with preeclampsia and normotensive women (226 vs. 225 kPa, respectively, P = 0.442) Conclusions: Fibroscan results for fibrosis were significantly higher in postpartum preeclamptic women (although within the normal range). Further studies are required in order to evaluate the usefulness of Fibroscan as an additional test in the evaluation and management of preeclampsia.     

Fatty Infiltration of Liver in Hyperlipidemic Patients

Hyperlipidemia is a known risk factor for fatty infiltration of the liver, a condition that can progress to cirrhosis and liver failure. The objectives of this study were to document the prevalence of fatty infiltration in the livers of hyperlipidemic patients and to identify the predictor variables associated with this condition. Over an 18-month recruitment period, clinical, biochemical, and radiologic assessments were performed in a cross-sectional manner in 95 adult patients referred to an urban hospital-based lipid clinic for evaluation and management of hyperlipidemia. The mean (±sd) age of the patients was 55 ± 13 years. Forty-eight (51%) were male. Fifty-two patients (55%) had hypercholesterolemia, 25 (26%) severe hypertriglyceridemia, 14 (15%) mixed hyperlipidemia, and 4 (4%) moderate hypertriglyceridemia. Obesity and diabetes were present in 36 (38%) and 12 (12%) of cases, respectively. A total of 61 (64%) patients had elevated liver enzyme tests. The most common enzyme abnormalities were an elevated serum ALT in 45 (47%) and GGT in 43 (45%) of patients. Ultrasound findings revealed diffuse fatty liver in 47 patients (50%), of which 21 cases (22%) were mild, 18 (19%) moderate, and 8 (9%) severe. The majority of patients with hypercholesterolemia [35/52 (67%)] had normal ultrasounds, whereas severe hypertriglyceridemia and mixed hyperlipidemia were frequently associated with radiologic evidence of fatty liver (odds ratios 5.9 and 5.1 respectively, P < 0.01). Independent predictors of fatty liver were; AST (P = 0.001), hyperglycemia (P = 0.02), and age (P = 0.04). In a model incorporating known risk factors for fatty liver, diabetes was the only risk factor other than hypertriglyceridemia that was significantly associated with fatty infiltration. No such effect was seen with age, gender, obesity, or alcohol consumption. In conclusions, the results of this study indicate that ultrasonographic evidence of fatty infiltration of the liver is evident in approximately 50% of patients with hyperlipidemia. Hypertriglyceridemia is the lipid profile most often associated with this condition. Serum AST values, hyperglycemia, and age independently predict the presence of fatty infiltration, while hypertriglyceridemia and diabetes are the only risk factors that significantly increase the risk of fatty infiltration in hyperlipidemic patients.
