amoxicillin-potassium-clavulanate-combination and Asthma

Previous studies have suggested that aggressive treatment of sinusitis can decrease bronchial hyperresponsiveness (BHR). However, there is still too little evidence to draw this conclusion, and the concept remains controversial.. A prospective, open-label study.. University children's hospital allergy and immunology center and radiologic department.. Sixty-one children with mild asthma and allergic rhinitis participated in the study. Forty-one of these 61 children had sinusitis, and the remainder had no sinusitis. Ten matched, nonatopic, healthy children were used as a control group.. Children with chronic sinusitis were placed into two groups. One group was treated with amoxicillin-clavulanate for 6 weeks and then with nasal saline solution irrigation for 6 weeks. For the other group, the treatment order was reversed. Children without chronic sinusitis received nasal saline solution irrigation for 12 weeks.. Clinical symptoms and signs of sinusitis, FEV(1), and BHR were analyzed in the patients before and after treatment.. The clinical symptoms and signs of sinusitis, but not FEV(1), showed a significant improvement after antibiotic treatment. After aggressive treatment for sinusitis, it was found that the provocative concentration of methacholine causing a 20% fall in FEV(1) of children with mild asthma and sinusitis was significantly higher after treatment.. The results suggest that every asthmatic patient needs to carefully evaluate to determine whether the patient has concomitant sinusitis. Respiratory infections that meet criteria for sinusitis, even if they do not exacerbate asthma, should be treated. It is suggested that sinusitis should always be kept in mind as a possible inducible factor for BHR, and that aggressive treatment of chronic sinusitis is indicated when dealing with an asthmatic patient who shows an unpredictable response to appropriate treatment. Moreover, the findings of this study provide more evidence for an association between sinusitis and asthma with respect to BHR.

Chronic rhinosinusitis is frequently associated with asthma. A Th2 cytokine pattern has been recently reported in chronic rhinosinusitis in asthmatic children.. To evaluate the effects of treating concomitant chronic rhinosinusitis on respiratory symptoms and function and immunopathological parameters in asthmatic children.. Eighteen children with moderate asthma (age range, 5 to 12 years) poorly controlled by high doses of inhaled corticosteroids and chronic rhinosinusitis were evaluated for symptoms, spirometry, and inflammation at baseline, after treatment, and 1 month after suspension of treatment. All of the children were treated with a combination of amoxicillin and clavulanate (20 mg/kg twice daily) and fluticasone propionate aqueous nasal spray (100 microg/d) for 14 days. A short course of oral corticosteroids was also prescribed (deflazacort, 1 mg/kg daily for 2 days, 0.5 mg/kg daily for 4 days, and 0.25 mg/kg daily for 4 days). Rhinosinusal lavage for cytokine measurements and a nasal scraping for cytologic analysis were performed in all patients before and after medical treatment.. A negative endoscopy result was demonstrated in 15 children after treatment. Symptoms and respiratory function significantly improved after treatment and 1 month later; 8 children had intermittent asthma and 10 had mild asthma. A significant reduction of inflammatory cell numbers was detected in all asthmatic children. Interleukin 4 levels significantly decreased (P < 0.001), whereas interferon-y levels increased (P < 0.001).. Treatment of chronic rhinosinusitis is able to improve symptoms and respiratory function in asthmatic children, reducing inflammatory cells and reversing the cytokine pattern from a Th2 toward a Th1 profile.

It is commonly recommended that microbiological assessment should accompany the use of antibiotics prone to resistance. We sought to estimate the rate of microbiology testing and compare this to dispensing of the World Health Organization classified "watch" group antibiotics in primary care.. Data from a cohort of older adults (mean age 69 years) were linked to Australian national health insurance (Pharmaceutical Benefits Scheme & Medicare Benefits Schedule) records of community-based antibiotic dispensing and microbiology testing in 2015. Participant characteristics associated with greater watch group antibiotic dispensing and microbiology testing were estimated using adjusted incidence rate ratios (aIRR) and 95% confidence intervals (CI) in multivariable zero-inflated negative binomial regression models.. In 2015, among 244,299 participants, there were 63,306 watch group antibiotic prescriptions dispensed and 149,182 microbiology tests conducted; the incidence rate was 0.26 per person-year for watch group antibiotic dispensing and 0.62 for microbiology testing. Of those antibiotic prescriptions, only 19% were accompanied by microbiology testing within - 14 to + 7 days. After adjusting for socio-demographic factors and co-morbidities, individuals with chronic respiratory diseases were more likely to receive watch group antibiotics than those without, e.g. asthma (aIRR:1.59, 95%CI:1.52-1.66) and chronic obstructive pulmonary disease (COPD) (aIRR:2.71, 95%CI:2.48-2.95). However, the rate of microbiology testing was not comparably higher among them (with asthma aIRR:1.03, 95%CI:1.00-1.05; with COPD aIRR:1.00, 95%CI:0.94-1.06).. Priority antibiotics with high resistance risk are commonly dispensed among community-dwelling older adults. The discord between the rate of microbiology testing and antibiotic dispensing in adults with chronic respiratory diseases suggests the potential for excessive empirical prescribing.

Pneumonia is an infection of the lung parenchyma that may result in pleural thickening, effusion, or an empyema. When there is air or gas in association with purulent exudate in the pleural cavity, a pyopneumothorax exists. The progression to pyopneumothorax under tension is extremely rare. We present a case of tension pyopneumothorax in a child.

A Th2 cytokine pattern has recently been reported both in allergic and nonallergic chronic rhinosinusitis in asthmatic children. The aim of the study was to evaluate the cytokine pattern in chronic rhinosinusitis in allergic and nonallergic asthmatic children before and after medical treatment. Thirty asthmatic children were evaluated, 18 males and 12 females (mean age 9.1 years). Sixteen were allergic and 14 were nonallergic. All children were asthmatic and suffered from chronic rhinosinusitis, whose diagnosis was confirmed by endoscopy. All of them were treated with amoxicilline-clavulanate (20 mg/kg b.i.d.) and fluticasone propionate aqueous nasal spray (100 microg daily) for 14 days; a short course of oral corticosteroid was also prescribed (deflazacort 1 mg/kg daily for 2 days, 0.5 mg/kg daily for 4 days and 0.25 mg/kg daily for 4 days). Rhinosinusal lavage and nasal cytology were performed in all subjects before and after medical treatment. IL4 and IFNgamma were measured by immunoassay and inflammatory cells were counted by conventional staining. Thirteen allergic children and 12 nonallergic children showed a negative endoscopy after the treatment. Allergic subjects showed a significant decrease of IL4 (p = 0.0002) and a significant increase of IFNgamma (p = 0.03) after the treatment. Nonallergic children showed a significant decrease of IL4 (p = 0.0007) and a nonsignificant increase of IFNgamma. A significant reduction of the inflammatory infiltrate was detected in all asthmatic children (p < 0.05). This study confirms a Th2 polarization in chronic rhinosinusitis both in allergic and nonallergic asthmatic children. Moreover, the medical treatment of chronic rhinosinusitis reversed the cytokine pattern from a Th2 towards a Th1 profile both in allergic and nonallergic children.
