Hemophagocytic syndrome due to Epstein-Barr virus and cytomegalovirus coinfection in a patient on adalimumab.

INTRODUCTION: Hemophagocytic syndrome (HPS) is a rare but potentially fatal complication of viral infections. Epstein-Barr virus (EBV) and cytomegalovirus (CMV) often infect patients receiving TNF-alpha inhibitors (TNF-α inhibitors). While EBV and CMV are well established infections for the development of infectious mononucleosis, coinfection with EBV and CMV is common among immunosuppressed patients and can result in a fatal course. In addition, such viral infections can cause HPS. To the best of our knowledge, we present here the first report of HPS induced by EBV and CMV coinfection during anti-TNFα inhibitor use. CASE REPORT: A 23-year-old man hospitalized with fever, elevated liver enzymes, lymphadenopathy, and hepatosplenomegaly was diagnosed with HPS associated with EBV and CMV coinfection while using adalimumab. No clinical improvement was observed after discontinuation of adalimumab. HPS complicated by EBV and CMV coinfection was finally diagnosed, and immediate administration of ganciclovir and prednisone was considered to have prevented a lethal clinical outcome. CONCLUSION: For cases showing unexplained fever, elevated liver enzymes, and lymphadenopathy while using anti-TNFα inhibitors, screening for EBV and CMV coinfection should be encouraged. In addition, HPS should be considered in patients with EBV and/or CMV infection receiving anti-TNFα inhibitors to facilitate early definitive therapy.

Erectile dysfunction in patients with chronic viral liver disease: its relevance to protein malnutrition.

BACKGROUND: In patients with chronic liver disease (CLD), quality of life is generally accepted as poor, especially for physical function. However, sufficient data regarding erectile function has not been shown in patients with CLD. The international index of erectile function (IIEF) is widely used to assess erectile function, and a short form of the IIEF was recently developed (IIEF-5). Using this questionnaire, we evaluated erectile dysfunction (ED) in patients with CLD. METHODS: A total of 117 Japanese patients (64 with chronic hepatitis [CH] and 53 with liver cirrhosis [LC]) were analyzed. The etiologies were hepatitis B virus (HBV) in 21, HCV in 94, and non-B non-C in 2. The IIEF-5 and Medical Outcomes Study Short Form 36 (SF-36) were administered to the patients, and biochemical analyses for items serum albumin, prothrombin time, bilirubin, and ammonia were also performed. RESULTS: The incidence of ED was 85% in the total cohort with CLD, 78% in those with CH, and 92% in those with LC (P < 0.05 between CH and LC). ED was found in 50% of CLD patients under age 50 years, in 79% aged 50-59, and in 100% aged over 60 (P, overall <0.001). The scores for ED severity correlated with increasing grades of a modified Child-Pugh classification (P < 0.05). Simple regression analysis showed age (P < 0.01), physical function (P < 0.001), role physical (P < 0.001), and social functioning (P < 0.05) on the SF-36, and serum albumin (P < 0.001) as significant determinants of ED. Multiple regression analysis identified age (P < 0.001) and serum albumin (P < 0.001) as independent significant factors that determined ED. CONCLUSIONS: These data clearly demonstrate that liver disease is the cause of ED in patients with CLD, and serum protein status could be relevant to this condition in these patients.

Prospective study on early virologic response to treatment with interferon alpha-2b plus ribavirin in patients with chronic hepatitis C genotype 1b.

To evaluate the predictive value of early virologic response (EVR) of achieving a sustained virologic response (SVR), an open, prospective trial including 42 patients with chronic hepatitis C genotype 1b was performed with directly observed 24-week treatment with interferon alpha-2b plus ribavirin. We assessed the predictive values of EVR at days 3, 7, 14, and weeks 4, 8, and 12 of the SVR. The SVR in an intention-to-treat analysis was 19.0%. Patients who reached SVR presented a significantly faster reduction in plasma viral load. Stepwise multiple logistic regression analysis of the factors (gender, age, IFN dosage, ribavirin dosage, HCV RNA, ISDR, and loss of HCV RNA at week 4) revealed that loss of HCV RNA at week 4 was the only independent variable of treatment outcome (P=0.0039). A viral load at treatment day 3 above 100kIU/ml, at day 7 above 50kIU/ml, and at day 14 above 10kIU/ml was 100% predictive for virologic non-response in all except 1 patient. The cutoff levels for HCV RNA at days 3 and 14 of treatment were associated with an algorithm of the failure to detect HCV RNA after 12 weeks of treatment. In conclusions, a very early virologic response assessment could be useful for prediction of later outcome of combination therapy in chronic hepatitis C genotype 1b.

Nocturnal branched-chain amino acid administration improves protein metabolism in patients with liver cirrhosis: comparison with daytime administration.

BACKGROUND: In an attempt to optimize oral branched-chain amino acid (BCAA) administration to improve serum albumin in cirrhotic patients, we compared the effects of nocturnal and daytime BCAA administration on protein metabolism in cirrhotic patients. METHODS: Twelve cirrhotic patients were enrolled in a short-term study. Patients were administered either conventional daytime BCAA granule or nocturnal BCAA for a week, and metabolic analyses were performed, followed by a crossover study in the next week. Another 12 patients, who showed no improvement of serum albumin level with previous daytime BCAA administration, were randomly assigned to either a nocturnal or a daytime BCAA administration group in a long-term study. RESULTS: Low Fischer's ratio, reduced respiratory quotient, and low serum albumin were observed at entry in cirrhotic patients. Whereas daytime BCAA administration improved nitrogen balance and Fischer's ratio, these 2 were further significantly improved after nocturnal BCAA administration. There were no changes in parameters of energy metabolism throughout the study. In the 3-month follow-up, a significant increase in serum albumin was observed in patients administered nocturnal BCAA but not in those administered daytime BCAA. CONCLUSIONS: Nocturnal BCAA administration improved serum albumin in cirrhotic patients who showed no improvement in serum albumin level with daytime BCAA administration. This effect could be partly caused by the improved protein sparing with this administration method.

Advantage of IFN-beta/alpha2b same-day administration for ribavirin-intolerant patients with chronic hepatitis C.

AIM: Although interferon (IFN)/ribavirin is the mainstream combination treatment for chronic hepatitis C in patients with a high viral load, ribavirin is problematic for women of childbearing age and patients with anemia. Therefore we needed to establish a new regimen without ribavirin. METHODS: We devised a new regimen (same-day beta/alpha2b) to administer IFN-beta and alpha2b on the same-day, and compared it with IFN-alpha2b alone and IFN-alpha2b plus ribavirin. The cases were 36 patients (26.1%) in whom ribavirin could not be used (young women, anemia, etc.) among 138 patients who underwent IFN treatment after ribavirin release. RESULTS: The percentages of patients withdrawing due to side-effects were 6.8%, 18.8% and 17.0% in the treatment with same-day beta/alpha2b, IFN-alpha2b alone and IFN-alpha2b plus ribavirin groups, respectively. In genotype 1b, the sustained viral response (SVR) was 28.6% (4/14), 13.6% (3/22) and 25.0% (8/32) with a high viral load, and 91.7% (11/12), 27.3% (3/11) and 57.1% (4/7) with a low viral load for the respective groups. According to a study on viral half-life during the early phase of IFN therapy, there was no difference among the regimens of same-day IFN-beta/alpha2b, beta alone, alpha2b alone and twice-daily treatment with IFN-beta. Same-day beta/alpha2b treatment showed a significantly higher SVR rate in moving type patients with a genotype 1b/high viral load. CONCLUSIONS: Same-day beta/alpha2b treatment resulted in few cases where therapy was discontinued and showed a high SVR rate. This regimen is especially appropriate in cases where ribavirin has been deemed unsuitable.

Psychoneurological symptoms during interferon therapy in patients with chronic hepatitis: prospective study on predictive use of Cornell Medical Index and electroencephalogram.

BACKGROUND/AIMS: We assessed the usefulness of the Cornell Medical Index (CMI) and electroencephalogram (EEG) in the prediction and early detection of psychoneurological symptoms associated with interferon (IFN) therapy for chronic viral hepatitis. METHODS: Forty-eight consecutive patients received IFN for chronic viral hepatitis for 8-24 weeks. CMI was measured before IFN therapy. Serial EEGs were recorded before IFN therapy, 2, 4 weeks, and thereafter every 4 weeks in the therapy. RESULTS: Psychoneurological symptoms including insomnia, depression, and restlessness were seen in 11 (23%) of 48 patients. Five (13%) of 40 patients with CMI I and II and six (75%) of eight with CMI III developed psychoneurological symptoms (P<0.001). Sensitivity, specificity, and predictive accuracy of CMI III were 55%, 95%, and 75%, respectively. Abnormal EEG such as slow basic rhythm, appeared in 13 patients (27%) during IFN therapy. Psychoneurological symptoms were seen in six (46%) of the 13 patients with abnormal EEG, and in five (14%) of 35 in whom EEG remained normal (P<0.05). CONCLUSIONS: CMI is useful for the prediction of IFN-induced psychoneurological symptoms in patients with chronic viral hepatitis. Serial EEGs contribute to the screening and auxiliarily assessing the adverse effects of IFN on the central nervous system.
