Results of Response-Guided Therapy with Pegylated Interferon Alpha 2a in Chronic Hepatitis B and D.

Pegylated interferon alpha 2a continues to be used for the treatment of chronic hepatitis D. The reported on-treatment virologic response varies between 17 and 47%, with relapses in more than 50% of these patients. No stopping rules have been defined, and the duration of the treatment is not clearly established, but it should be between 48 and 96 weeks. In total, 76 patients with compensated liver disease treated with peg-interferon according to the Romanian National protocol for the treatment of hepatitis D were retrospectively included. The duration of treatment was up to 96 weeks, with the following stopping rules: less than a 2 log HDV RNA decrease by week 24 and less than a 1 log decrease every 6 months afterwards. Six months after stopping the treatment, it can be restarted for unlimited cycles. The inclusion criteria were aged above 18, HBs Ag-positive, HDV RNA detectable, ALT above ULN and/or liver fibrosis at least F1 at liver biopsy, or Fibrotest and/or Fibroscan higher than 7 KPa and/or inflammation at least A1 at liver biopsy or Fibrotest. We monitored our patients for a total period of 4 years (including those that repeated the cycle). After the first 6 months of treatment, 27 patients (35.5%) had a greater than 2 log HDV RNA decrease, 19 of them achieving undetectable HDV RNA. Seventeen patients (22.3%) had undetectable HDV RNA 24 weeks after stopping 96 weeks of treatment, and none relapsed in the following 2 years. Of these 17 patients, 6 were cirrhotic, and 4 had F3. Undetectable HDV RNA at 24 weeks was the only parameter that predicted a long-term suppression of HDV RNA. In 49 patients, the treatment was stopped after 6 months according to protocol, but it was restarted 6 months later. Five of these patients finished a 48-week course of treatment; none achieved undetectable HDV RNA. During the first course of therapy, 45 patients had at least one moderate adverse reaction to treatment. In one patient, the treatment was stopped due to a serious adverse event (osteomyelitis). Treatment doses had to be reduced in 29 patients. The virologic response at week 24 can select the patients who will benefit from continuing the treatment from those who should be changed to another type of medication when available.

Primary Hepatic Marginal Zone Lymphoma in a Patient with Chronic Hepatitis C.

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) is a low-grade malignant lymphoma that appears frequently in the stomach, but other sites can also be involved: the intestinal tract, lungs, head, neck, skin, thyroid, breasts and liver. Recently, epidemiological evidences support the idea that there is an association between hepatitis C and B-cell non-Hodgkin lymphomas (that include MALT as a subtype). Primary non-Hodgkin lymphomas confi ned only to the liver are very rare (only 0.016% of all cases of all non-Hodgkin's lymphomas) and MALT is not the most frequent type. We present the case of a male patient, age 62, known with chronic hepatitis C, previously relapser a" er a 72 week treatment with peg-interferon alfa and ribavirin that was diagnosed at three years a" er the relapse with multiple focal liver lesions. One of the tumors was surgically removed and the histological exam performed demonstrated an extranodal marginal zone lymphoma with small B-cell with plasmacytoid diff erentiation confi ned only to the liver. Direct acting antiviral (DAA) therapy was started, but the virologic clearance was not obtained by week 10, leading to a change of DAA regimen at week 12. The antiviral therapy was continued until week 24. Imaging showed an increase in number and size of the focal lesions until week 12. At week 12 chemo- and immune-therapy was started with bendamustine and rituximab. A" erwards the evolution was favorable, the patient being now in complete remission and with undetectable viral load.

Efficacy and safety of tigecycline versus levofloxacin for community-acquired pneumonia.

BACKGROUND: Tigecycline, an expanded broad-spectrum glycylcycline, exhibits in vitro activity against many common pathogens associated with community-acquired pneumonia (CAP), as well as penetration into lung tissues that suggests effectiveness in hospitalized CAP patients. The aim of the present study was to compare the efficacy and safety of intravenous (IV) tigecycline with IV levofloxacin in hospitalized adults with CAP. METHODS: In this prospective, double-blind, non-inferiority phase 3 trial, eligible patients with a clinical diagnosis of CAP supported by radiographic evidence were stratified by Fine Pneumonia Severity Index and randomized to tigecycline or levofloxacin for 7-14 days of therapy. Co-primary efficacy endpoints were clinical response in the clinically evaluable (CE) and clinical modified intent-to-treat (c-mITT) populations at test-of-cure (Day 10-21 post-therapy). RESULTS: Of the 428 patients who received at least one dose of study drug, 79% had CAP of mild-moderate severity according to their Fine score. Clinical cure rates for the CE population were 88.9% for tigecycline and 85.3% for levofloxacin. Corresponding c-mITT population rates were 83.7% and 81.5%, respectively. Eradication rates for Streptococcus pneumoniae were 92% for tigecycline and 89% for levofloxacin. Nausea, vomiting, and diarrhoea were the most frequently reported adverse events. Rates of premature discontinuation of study drug or study withdrawal because of any adverse event were similar for both study drugs. CONCLUSION: These findings suggest that IV tigecycline is non-inferior to IV levofloxacin and is generally well-tolerated in the treatment of hospitalized adults with CAP.
