Oral treatment of acute bronchitis with thyme-primrose combination for about 11 days was superior to placebo in terms of efficacy. The treatment was safe and well tolerated.

Background Allergic bronchopulmonary aspergillosis (ABPA) is a severe hypersensitivity reaction to aspergillus species colonizing the airways of patients with asthma or cystic fibrosis. Biologics including anti-IgE and anti-IL5 antibodies have strongly changed the treatment of severe asthmatics and have partly been reported to be effective in the treatment of ABPA. Recently, dupilumab, an anti-IL4-Rα antibody which inhibits signaling by the Th2-cytokines IL4 and IL13, has been approved for the treatment of severe asthma. Case presentation Here, we report the case of a 49-year-old woman with severe asthma and ABPA, who was uncontrolled despite maximum inhalative therapy, anti-IL5-Rα antibody and continuous oral steroid therapy. Moreover, trials of itraconazole as well as omalizumab showed insufficient efficacy. Lung function revealed peripheral obstruction. FeNO and IgE were increased, eosinophils were suppressed under treatment while marked increases had been documented previously. Switching to dupilumab led to a complete resolution of pulmonary symptoms, resolution of exacerbations and complete withdrawal of oral steroids. A drastic improvement in lung function was noted, with an increase in FEV1 of almost 1 l. FeNO was normalized and IgE strongly reduced. Conclusion Our case highlights that a patient may exhibit differential treatment responses to the currently available asthma biologics and suggests switching treatment if outcome is insufficient. A potential role for dupilumab in the treatment of ABPA warrants future studies.

Eight healthy volunteers each received 2.0 g of ceftazidime by constant intravenous infusion over 20 min twice daily every 12 h for 8 days. Concentrations of ceftazidime in serum and urine were measured by a microbiological assay and by high-pressure liquid chromatography. Qualitative and quantitative studies on aerobic and anaerobic fecal flora were carried out before, during, and 2 weeks after the end of treatment. The mean (± standard deviation) maximum drug concentration in serum at the end of the 20-min infusion (day 1) was 185.5 ± 28.5 ,ug/ml, decreasing to 0.8 ± 0.4 pg/ml after 12 h. The mean recovery of drug in urine at 12 h was 71. No accumulation of ceftazidime could be observed during the 8-day study period. Mean maximum drug levels in serum were 185.5 to 214.5 pLg/ml, and mean trough levels were 0.8 to 1.1 ,ug/ml (days 1 to 8). No severe side effects were noted. During ceftazidime treatment, anaerobes were left intact, whereas members of the family Enterobacteriaceae could be isolated from stool in only three of eight subjects. Two weeks after discontinuation of the drug, all stool specimens contained ampicillin-and cefazolin-resistant gram-negative rods.

Nosocomial pneumonias, especially in ventilated patients, are a continuing problem in modern medicine. Pathogens most commonly involved with these pneumonias are Enterobacteriaceae, Ps. aeruginosa and S. aureus. Several prevention measures for nosocomial pneumonia are possible such as parenteral and topical antibiotics--a very controversial issue. Several studies with parenteral antibiotics, starting as early as 1954, could not prove any benefit of parenteral antibiotics in pneumonia prevention. Topical antibiotics, starting with polymyxin or gentamicin via the endotracheal tube in the 70s, gave controversial results. In a prospective, randomized, double-blind placebo controlled study with gentamicin via the endotracheal tube in ventilated ICU patients we found no significant reduction of pneumonia rate and mortality. However, the combined approach (SDD) of oropharyngeal, gastrointestinal and parenteral use of certain antibiotics appears to give promising results in specific patient subgroups such as ventilated polytrauma patients in ICU.
