Levofloxacin (LVFX) is one of respiratory quinolones with wide spectrum of antimicrobial efficacy for Gram-positive and -negative bacteria and also atypical bacteria, and 500 mg of intravenous LVFX infusion has recently been able to use once daily based on pharmacokinetics-pharmacodynamics in Japan. So far, there had been no reports of the prospective studies evaluating efficacy and safety of LVFX in patients with nursing and healthcare-associated pneumonia (NHCAP). This study was conducted to evaluate prospectively the efficacy and safety of LVFX in patients with NHCAP categories B and C (other antibacterial agents were allowed to use with LVFX) according to Japanese guideline for NHCAP by the Japanese Respiratory Society (JRS). LVFX 500 mg was intravenously administered once daily, and the clinical efficacy and safety were evaluated by clinical symptoms, peripheral blood laboratory findings and chest X-rays. Sixty-two patients (average age was 81.2 years old, female/male was 22/40) were firstly registered and evaluated for the safety of LVFX, and eventually 54 patients were enrolled for the evaluation of clinical efficacy of LVFX. The percentage of these 54 patients aged over 65 years old was 96.3%, NHCAP category B/C was 33/21. The efficacy of LVFX in all 54 patients evaluated was 85.2% (categories B/C of NHCAP was 81.8/90.5%). In addition, the efficacies of LVFX in each pneumonia severity category by A-DROP system by JRS in NHCAP patients were 100% in mild, 86.7% in moderate, 77.8% in severe/very severe. Nine patients (2 with liver dysfunction, 6 with renal dysfunction and 1 with thrombocytopenia) out of 62 patients were reported to have possible adverse effects of LVFX. All of the patients with liver and renal dysfunctions after starting LVFX administration demonstrated mild dysfunctions and continued LVFX treatment, and these dysfunctions normalized soon after cessation of LVFX. LVFX was changed to other antibacterial agent in one patient with thrombocytopenia, and also thrombocytopenia was normalized thereafter. In conclusion, LVFX is effective and relatively safe for categories B and C in patients with NHCAP.

Moxifloxacin (MFLX) is a respiratory quinolone, and is effective against not only Gram-positive and negative bacteria but also anaerobes. There has been no prospective studies evaluating the efficacy and safety of MFLX in patients with nursing and healthcare-associated pneumonia (NHCAP). Therefore, we assessed the efficacy and safety of MFLX in patients with NHCAP. NHCAP patients with mild and moderate severity assessed by the A-DROP system in community-acquired pneumonia guideline proposed by Japan Respiratory Society visited our hospitals from April 2011 to March 2012. Clinical symptoms, chest X-ray films and/or computed tomography, peripheral white and red blood cell and platelet counts, serum CRP, AST, ALT, BUN, creatinine were evaluated. Forty patients were eventually evaluated, and average age was 74.1 years old, male/female were 21/19, 92.5% (37/40) of them had one or more comorbidities. Median duration of MFLX administration was 7.1 days (4-15 days). The efficacy of MFLX in all patients was 87.5% (35/40). The efficacies in each age group were 87.9% (aged over 65 years old), 85.7% (aged under 64 years old), and in each pneumonia severity group by the A-DROP system were 91.7% (mild), 85.7% (moderate). Diarrhea and swelling of the breast were observed in one patient (2.5%) after starting MFLX administration. Mild elevated transaminases were observed in three patients (7.5%), and mild renal dysfunction was observed in two patients (5.0%). All abnormally increased levels of transaminases and serum creatinine were recovered after a cessation of MFLX. MFLX is effective and safe in patients with NHCAP.

Aim: To clarify the utility of sepsis evaluation using the Quick Sequential Organ Failure Assessment (qSOFA) tool in addition to the Pneumonia Severity Index (PSI); age, dehydration, respiration, orientation and blood pressure (A‐DROP) index; and immunodeficiency, respiration, orientation, age and dehydration (I‐ROAD) scoring systems, and risk factor evaluation of potentially drug‐resistant (PDR) pathogens are suggested in the 2017 guidelines for pneumonia of the Japanese Respiratory Society in nursing‐ and healthcare‐associated pneumonia patients. Methods: We included 289 hospitalized nursing‐ and healthcare‐associated pneumonia patients between April 2016 and March 2017, and investigated the ability of PSI, A‐DROP, I‐ROAD and qSOFA to predict pneumonia‐related mortality. We also evaluated the associations among the risk factors for PDR pathogens, the detection ratio of PDR pathogens and pneumonia‐related mortality. Results: The mortality rate of pneumonia during hospitalization was 6.9% (20/289). The area under the curve for pneumonia‐related mortality predicted using PSI, A‐DROP, I‐ROAD and qSOFA was 0.697 (95% confidence interval [CI] 0.59–0.80), 0.63 (95% CI 0.51–0.76), 0.61 (95% CI 0.52–0.70) and 0.701 (95% CI 0.59–0.81), respectively. In addition, higher areas under the curve were observed for pneumonia‐related mortality predicted according to a combination of PSI and hypoalbuminemia (<2.5 g/dL) (0.75, 95% CI 0.64–0.86), and qSOFA and hypoalbuminemia (0.74, 95% CI 0.62–0.86) than for PSI and qSOFA alone. No significant associations were observed among the risk factors for PDR pathogens, the detection ratios of PDR pathogens and pneumonia‐related mortality. Conclusions: qSOFA and the combination of qSOFA and hypoalbuminemia might be simple and useful evaluation tools for predicting pneumonia‐related mortality in nursing‐ and healthcare‐associated pneumonia patients.
