Plasma MERS-CoV RT-PCR may serve as an effective tool to predict MERS-CoV-associated mortality. Older age and comorbid conditions may have contributed to the lack of efficacy of IFN-α2a or IFN-β1a with ribavirin in treating MERS-CoV. Absence of fever should not exclude MERS-CoV.

Middle East Respiratory Syndrome Coronavirus (MERS CoV) may cause severe pneumonia with significant morbidity and mortality, particularly in patients with multiple comorbid condition. MERS CoV pneumonia has not been previously reported in patients with Human Immunodeficiency Virus (HIV). Herein, we report a case of MERS CoV pneumonia with a successful outcome in a patient recently diagnosed with HIV.

Many patients with chronic hepatitis C (HCV) infection undergoing treatment with pegylated interferon-alpha (PEG-IFN-alpha) and ribavirin develop neutropenia requiring dose reduction or granulocyte colony-stimulating factor (G-CSF) supplement. We analysed the database of patients who completed treatment for chronic HCV infection between 2003 and 2006. Patients with absolute neutrophil counts below 1000 cells/microL were initiated on G-CSF (G-CSF group) while a matching group of patients who received anti-HCV treatment without developing neutropenia were used as a control group (non-G-CSF group). Patients on the G-CSF arm were divided into two subgroups based on the timing of G-CSF administration relative to PEG-IFN-alpha administration. Of the 163 patients with HCV infection, 30 patients received G-CSF, most of who were maintained on 300 microg of G-CSF once a week. Administration of G-CSF 2 days before or after each dose of PEG-IFN-alpha did not make a significant difference in the neutrophil counts. In the G-CSF arm, 23 of 30 patients (77%) had undetectable end-of-treatment viral response which was comparable with 27 of 30 in the control group (90%; P = 0.17). There was no statistically significant difference in the sustained viral response between the two groups (61%vs 76%, P = 0.18). In most patients PEG-IFN-alpha induced neutropenia improved with a once-a-week dose of G-CSF with a comparable virological outcome. Timing of G-CSF administration did not make any significant impact on the patient's neutrophil counts but was better tolerated when given 2 days apart from PEG-IFN-alpha.

We used hospital antibiograms to assess predominant pathogens and their patterns of in vitro antimicrobial resistance in central Illinois, USA. We found a lack of information about national guidelines for in vitro antimicrobial susceptibility testing and differences in interpretation among laboratories in the region.
