Reduced antibiotic use after initial treatment of acute respiratory infections with phytopharmaceuticals- a retrospective cohort study

Exploring the association between phytopharmaceutical use and antibiotic prescriptions in upper respiratory infections: results from a German cohort study evaluating the impact of naturopathy qualifications of general practitioners using routine data

Background

Antibiotic resistance is a significant global health threat, exacerbated by inappropriate prescribing practices, particularly for upper respiratory infections that are predominantly viral. Complementary and Integrative Medicine (CIM), including the use of phytopharmaceuticals, offers a potential strategy to reduce antibiotic prescriptions.

Objective

This study aimed to describe the impact of General Practitioners' (GPs) naturopathy (NP) qualifications and phytopharmaceutical prescriptions on the rate of antibiotic prescribing for upper respiratory infections (RTI).

Methods

We conducted a retrospective cohort study using routine data from the CONTinuous morbidity registration Epidemiologic NeTwork (CONTENT), which includes over 200,000 patients across four federal states in Germany. The study included data from n = 36 GPs who recorded at least one ICD-10 diagnosis of RTI. Antibiotic and phytopharmaceutical prescriptions were identified and analyzed through mixed-effects logistic regression models to explore the influence of GPs' naturopathy qualifications and phytopharmaceutical use on antibiotic prescribing patterns.

Results

The study included 40,344 patients managed by 36 GPs. Prescriptions of phytopharmaceuticals significantly reduced the likelihood of antibiotic use (OR 0.48, 95% CI 0.45-0.52). Additionally, holding a naturopathy qualification was associated with lower rates of antibiotic prescriptions (OR 0.73, 95% CI 0.69-0.78). The interaction between naturopathy qualification and phytopharmaceutical prescriptions also showed a significant effect (OR 1.43, 95% CI 1.27-1.62). Patient's year of birth influenced prescribing patterns indicating a reduction of antibiotic prescriptions for younger patients, while patients' gender did not reveal a significant effect.

Conclusion

Prescriptions of phytopharmaceuticals were significantly associated with a decrease antibiotic prescriptions among GPs, especially when combined with naturopathy qualifications. Training in naturopathic approaches could enhance antibiotic stewardship efforts in primary care settings, suggesting that broader integration of CIM elements into medical training could be beneficial in mitigating antibiotic resistance.

Multiple mechanisms enable broad-spectrum activity of the Pelargonium sidoides root extract EPs 7630 against acute respiratory tract infections

There is clinical evidence showing that the Pelargonium sidoides root extract EPs 7630 is a safe and effective treatment for a range of acute infectious respiratory illnesses. Moreover, EPs 7630 has been shown to reduce the use of antibiotics, which is important in the context of rising antibiotic resistance levels. A wide range of mechanisms appears to contribute to the beneficial effects of EPs 7630, e.g. antibacterial, antiviral, immunomodulatory, and epithelial barrier effects. This broad spectrum of pharmacological activities seems to enable the clinical activity of EPs 7630 against multiple respiratory infections. In particular, the combination of antiviral and immunomodulatory effects may enable EPs 7630 to tackle acute viral respiratory infections both in early stages of the disease process, which are driven by virus replication, as well as in later stages, which are caused by an overshooting immune response. Hence, EPs 7630 is a prime example of a plant extract with evidence-based clinical efficacy, including a solid understanding of the underlying mechanisms of action. The example of EPs 7630 demonstrates that plant extracts have a potential role as evidence-based clinical treatments and that they deserve pre-clinical and clinical testing and investigation in the same way as any other drug class.

Long-term benefits of EPs® 7630 in patients with acute sinusitis: a real-world cohort study

Background: We evaluated whether EPs® 7630 prescription in patients with acute sinusitis (AS) is associated with less frequent recurrence of AS, occurrence of chronic sinusitis or nasal polyps, or fewer antibiotic prescriptions. Methods: This retrospective cohort study used electronic medical records from the IQVIA Disease Analyzer database. Associations between initial therapy [EPs® 7630, antibiotics, intranasal corticosteroid (INCS), or corticosteroid-free nasal spray within 3 days of AS diagnosis] and AS recurrence, incidence of chronic sinusitis or nasal polyps or rate of antibiotic prescription were studied using multivariable Cox or logistic regression models, adjusting for sex, age, insurance status, month of diagnosis, and comorbidity. Results: A total of 216,360 patients were analyzed. INCS prescription was associated with a higher risk of recurrent AS (HR: 1.40; 95% CI: 1.01-1.92) and a higher incidence of chronic sinusitis or nasal polyp diagnosis (HR: 1.39; 95% CI: 1.01-1.92) compared to EPs® 7630. Initial antibiotic therapy was significantly associated with higher risk of new antibiotic prescription in the period of 31-365 days after the index date compared to EPs® 7630 (OR: 2.20; 95% CI: 1.66-2.92). Conclusion: EPs® 7630 prescription is associated with long-term benefits in AS patients. EPs® 7630 can help to reduce inappropriate antibiotic use and might reduce the risk of chronic sinusitis or nasal polyps.

Proposed mechanisms of action of herbal drugs and their biologically active constituents in the treatment of coughs: an overview

Various medicinal plants find their use in cough treatment, based on traditions and long-term experience. Pharmacological principles of their action, however, are much less known. Herbal drugs usually contain a mixture of potentially active compounds, which can manifest diverse effects. Expectorant or antitussive effects, which can be accompanied by others, such as anti-inflammatory or antibacterial, are probably the most important in the treatment of coughs. The aim of this review is to summarize the current state of knowledge of the effects of medicinal plants or their constituents on cough, based on reliable pharmacological studies. First, a comprehensive description of each effect is provided in order to explain the possible mechanism of action in detail. Next, the results related to individual plants and substances are summarized and critically discussed based on pharmacological in vivo and in vitro investigation.

Current state of research on the clinical benefits of herbal medicines for non-life-threatening ailments

Herbal medicines are becoming increasingly popular among patients because they are well tolerated and do not exert severe side effects. Nevertheless, they receive little consideration in therapeutic settings. The present article reviews the current state of research on the clinical benefits of herbal medicines on five indication groups, psychosomatic disorders, gynecological complaints, gastrointestinal disorders, urinary and upper respiratory tract infections. The study search was based on the database PubMed and concentrated on herbal medicines legally approved in Europe. After applying defined inclusion and exclusion criteria, 141 articles were selected: 59 for psychosomatic disorders (100% randomized controlled trials; RCTs), 20 for gynecological complaints (56% RCTs), 19 for gastrointestinal disorders (68% RCTs), 16 for urinary tract infections (UTI, 63% RCTs) and 24 for upper respiratory tract infections (URTI) (79% RCTs). For the majority of the studies, therapeutic benefits were evaluated by patient reported outcome measures (PROs). For psychosomatic disorders, gynecological complaints and URTI more than 80% of the study outcomes were positive, whereas the clinical benefit of herbal medicines for the treatment of UTI and gastrointestinal disorders was lower with 55%. The critical appraisal of the articles shows that there is a lack of high-quality studies and, with regard to gastrointestinal disorders, the clinical benefits of herbal medicines as a stand-alone form of therapy are unclear. According to the current state of knowledge, scientific evidence has still to be improved to allow integration of herbal medicines into guidelines and standard treatment regimens for the indications reviewed here. In addition to clinical data, real world data and outcome measures can add significant value to pave the way for herbal medicines into future therapeutic applications.

Changes in the Prescription of Antibiotics and Phytopharmaceuticals in Children Treated for Acute Upper and Lower Respiratory Tract Infections in Pediatric Practices in Germany in 2013, 2018, and 2022

Background: Little is known about the recent trends in antibiotic and phytopharmaceutical prescribing for acute upper (URIs) and lower respiratory tract infections (LRIs) in children and adolescents. Therefore, this study investigated changes in the prescription of antibiotics and phytopharmaceuticals in children diagnosed with acute URIs and LRIs in pediatric practices in Germany in 2013, 2018, and 2022. Methods: The present retrospective study included children aged 2-12 years diagnosed with acute URIs or LRIs in one of 180 pediatric practices in 2013, 2018, and 2022. The URIs included nasopharyngitis, sinusitis, pharyngitis, tonsillitis, laryngitis and tracheitis, and upper respiratory infections of multiple and unspecified sites, while the LRIs corresponded to bronchitis. The primary outcomes were the proportion of children being prescribed antibiotics and the proportion of those being prescribed phytopharmaceuticals. Results: A total of 120,894 children were diagnosed with acute URIs or LRIs in 2013 compared to 116,844 in 2018 and 127,821 in 2022. The prevalence of antibiotic prescription decreased for all diagnoses between 2013 and 2022. This decrease was statistically significant for both 2013-2018 and 2018-2022 for nasopharyngitis, pharyngitis, and bronchitis. Meanwhile, there was a significant increase in the use of phytopharmaceuticals for all diagnoses between 2013 and 2018. The prevalence of phytopharmaceutical prescription decreased slightly between 2018 and 2022, but this decrease was generally not statistically significant. Conclusions: The prescription of antibiotics has decreased and that of phytopharmaceuticals has increased in children diagnosed with acute URIs and LRIs in Germany over the last decade. More data are needed to corroborate these findings in other settings.

Efficacy and effectiveness of the herbal medicinal product BNO 1016 in the management of acute rhinosinusitis in the context of antibiotic stewardship

OBJECTIVES

To substantiate the clinical efficacy and investigate the real-world effectiveness of the herbal medicinal product BNO 1016 in acute rhinosinusitis (ARS) in the context of antibiotic stewardship.

METHODS

We performed a meta-analysis of the clinical trials ARhiSi-1 (EudraCT No. 2008-002794-13) and ARhiSi-2 (EudraCT No. 2009-016682-28) comprising 676 patients, analyzing the reduction of the Major Symptom Score (MSS) and improvement of the Sino-Nasal Outcome Test 20 (SNOT-20) by the herbal medicinal product BNO 1016. In addition, we performed a retrospective cohort study including 203,382 patients, comparing the real-life effectiveness of BNO 1016 in reducing ARS-related adverse outcomes in comparison to antibiotics and several other established therapies.

RESULTS

Treatment with BNO 1016 ameliorated symptoms of ARS by reducing MSS by 1.9 points (p < 0.0001) and improved quality of life (QoL) for patients by improving SNOT-20 by 3.5 points (p = 0.001) in comparison to placebo. In patients with moderate/severe symptoms, the positive effects of BNO 1016 were even more pronounced (MSS: -2.3 points (p < 0.0001); SNOT-20: -4.9 points (p = 0.0158)). In addition, treatment with BNO 1016 was as effective or significantly more effective in reducing the risk for adverse ARS-related outcomes such as follow-up antibiotic prescriptions, sick leave ≥7 days or medical appointments due to ARS, especially when compared to antibiotics.

CONCLUSION

BNO 1016 is a safe and effective treatment for ARS that can help reduce the overuse of antibiotics.

Potential Saving of Antibiotics for Respiratory Infections in Several European Countries: Insights from Market Research Data

Antibiotics represent an essential pillar in the treatment of respiratory infections (RI). Overuse of antibiotics in avoidable cases and inappropriate application in bacterial infections facilitate treatment resistance, threatening their effectiveness and causing a significant healthcare challenge. We therefore assessed the savings potential for antibiotics in ambulant care of selected RI (bronchitis and cough, pharyngitis, rhinosinusitis) in several European countries based on market research data for the year 2019. Number of antibiotic packages sold in pharmacies varied, with highest values in Serbia and France, and lowest in Sweden and Switzerland. Selected RI contributed nearly half of overall ambulant antibiotic prescriptions, with around one fifth given for bronchitis and cough; the vast majority was estimated to be of viral origin with potentially avoidable antibiotic use. Antibiotic consumption for selected RI in eight European countries (Austria, Belgium, the Czech Republic, France, Germany, Poland, Slovakia, and Switzerland) amounted to nearly 100 million, with an overall savings potential between 66.2 and 83.7 million packages. The highest estimated volume of avoidable antibiotics was in France (44.7 million, 0.80 per capita), and lowest in Switzerland (1.4 million, 0.18 per capita). Due to substantial savings potential, prudent use of antibiotics and adequate application of alternatives should be promoted in daily practice.

Effects of EPs 7630 on the duration of inability to work in acute bronchitis - a meta-analysis

Background

Acute bronchitis (AB) has an enormous economic impact through lost working time. We investigated whether treatment with Pelargonium extract EPs 7630 may reduce the time of inability to work.

Methods

A meta-analysis of double-blind, randomized, placebo-controlled trials with adult patients suffering from AB was performed. The average number of days of inability to work and the proportion of patients who were still unable to work after one week's treatment were assessed.

Results

Four clinical trials with a total of 1,011 evaluable patients who received the marketed dosage of EPs 7630 (n=505) or placebo (n=506) for seven days were included in the meta-analysis. At baseline, 845/1,011 patients (83.6%) were unable to work. In the four trials, the proportion decreased to between 19 and 14% for EPs 7630 and to between 41 and 55% for placebo (meta-analysis risk ratio and 95% confidence interval: 0.35; 0.26-0.45; p<0.001). For the number of sick days, a weighted mean difference of 1.73 days (1.17-2.29 days; p<0.001) favoring EPs 7630 was observed.

Conclusions

For adults suffering from AB, this meta-analysis demonstrates that seven days' treatment with Pelargonium sidoides extract EPs 7630 significantly reduces the average number of sick days and significantly increases the proportion of patients who are able to return to work.

Prevalence of Antibiotic Prescription in Patients with Acute Rhinosinusitis Treated by General Practitioners and Otolaryngologists in Germany-A Retrospective Cohort Study

(1) Background: The goal of this retrospective cohort study, based on real-world data and conducted in Germany, was to investigate the prevalence of antibiotic (AB) prescription in patients with acute rhinosinusitis (ARS). (2) Methods: Data from the Disease Analyzer database were used for this cross-sectional study. Patients aged ≥18 years diagnosed with acute sinusitis by general practitioners (GPs) and ear, nose, throat (ENT) specialists between January 2012 and December 2020 were included. The main outcome of the study was the proportion of patients with ARS who received an AB prescription on the day of diagnosis or within three days afterwards. The proportion was estimated separately for patients treated by GPs and ENTs, and also for five age groups, as well as women and men. (3) Results: In total, 308,095 patients were diagnosed with ARS (187,838 by GPs and 120,257 by ENTs). 50.9% of patients treated by GPs and 50.0% treated by ENTs received an AB prescription. AB prevalence increased with age from 46.9% in the age group 18−30 years to 55.5% in the age group > 60 years. (4) Conclusions: We have shown a high prevalence of potentially inappropriate AB prescription for adult patients with ARS in both GP and ENT practices and also among both women and men and in several age groups. There is an urgent need for interventions to reduce inappropriate AB use.

Contribution of Symptomatic, Herbal Treatment Options to Antibiotic Stewardship and Microbiotic Health

Epithelial surfaces in humans are home to symbiotic microbes (i.e., microbiota) that influence the defensive function against pathogens, depending on the health of the microbiota. Healthy microbiota contribute to the well-being of their host, in general (e.g., via the gut-brain axis), and their respective anatomical site, in particular (e.g., oral, urogenital, skin, or respiratory microbiota). Despite efforts towards a more responsible use of antibiotics, they are often prescribed for uncomplicated, self-limiting infections and can have a substantial negative impact on the gut microbiota. Treatment alternatives, such as non-steroidal anti-inflammatory drugs, may also influence the microbiota; thus, they can have lasting adverse effects. Herbal drugs offer a generally safe treatment option for uncomplicated infections of the urinary or respiratory tract. Additionally, their microbiota preserving properties allow for a more appropriate therapy of uncomplicated infections, without contributing to an increase in antibiotic resistance or disturbing the gut microbiota. Here, herbal treatments may be a more appropriate therapy, with a generally favorable safety profile.

Synergistic Effect of Polyphenol-Rich Complex of Plant and Green Propolis Extracts with Antibiotics against Respiratory Infections Causing Bacteria

Bacterial infections are a prevalent complication after primary viral respiratory infections and are associated with high morbidity and mortality. Antibiotics are widely used against bacterial respiratory pathogens; however, the rise in antibiotic-resistant strains urges us to search for new antimicrobial compounds, including ones that act synergistically with antibiotics. In this study, the minimal inhibitory (MIC) and minimal bactericidal (MBC) concentrations of a polyphenol-rich complex of green propolis, Tabebuia avellanedae bark, and Olea europaea leaf extracts against Staphylococcus aureus, Haemophilus influenzae, and Klebsiella pneumoniae were determined, followed by an analysis of the synergistic effect with clarithromycin, azithromycin, and amoxiclav (875/125 mg amoxicillin/clavulanic acid). A combination of extracts showed activity against all three bacterial strains, with MIC values ranging from 0.78 to 12.5 mg/mL and MBC values from 1.56 to 12.5 mg/mL. The extracts showed synergistic activity with azithromycin and clarithromycin against S. aureus, with clarithromycin against K. pneumoniae, and with all three tested antibiotics against H. influenzae. Synergy with clarithromycin was additionally evaluated in a time-kill assay where the synergistic effects against S. aureus and K. pneumoniae were seen within the first 6 h of incubation. The results show the potential of polyphenol-rich extracts in enhancing the efficacy of antibiotic therapy and indicate their potential to be used in the management of respiratory infections.

Association between ivy leaves dry extract EA 575 prescriptions and antibiotic use, sick leave duration, and repeated infections in adult patients

OBJECTIVES

The present study aimed to analyze the association between the prescription of ivy leaf dry extract EA 575 (licensed under the trade name Prospan® in Germany) and the incidence of antibiotic use, incident bacterial complications, and days of sick leave in adult patients with cold diseases.

METHODS

This retrospective cohort study was based on the IQVIA Disease Analyzer database and included adult patients from 1032 general practices in Germany with a documentation of common cold between 2017 and 2020 (index date) and prescription of either EA 575 or an antibiotic drug within 3 days after index date. 1:1 propensity score matching based on age, sex, index month, physician, health insurance status, and the Charlson Comorbidity Index was carried out. Univariable regression models were used to investigate the association between EA 575 prescription and defined outcomes.

RESULTS

Data of 7034 patients treated with EA 575 and 7034 matched patients receiving an antibiotic were available. EA 575 prescription was associated with significantly lower odds of an antibiotic prescription in the time periods of 4-30 days (OR: 0.83; 95% CI: 0.72-0.96) and 31-365 days (OR: 0.44; 95% CI: 0.40-0.48) after the index date. EA 575 prescription was significantly associated with a lower rate of sick leave of more than 7 days (33.0% vs. 37.7%, OR: 0.81; 95% CI: 0.73-0.90) in patients with any sick leave, as well as with lower odds of a new cough diagnosis (OR: 0.91, 95% CI: 0.85-0.98) when compared to antibiotic prescription.

CONCLUSION

Our study provides further evidence that the use of phytopharmaceuticals, in particular ivy leaf dry extract EA 575, could contribute to a reduction in the number of inappropriate antibiotic prescriptions for respiratory infection with cough symptoms.

Effectiveness and tolerability of the thyme/ivy herbal fluid extract BNO 1200 for the treatment of acute cough: an observational pharmacy-based study

OBJECTIVE

Efficacy and safety of an oral thyme/ivy syrup for the treatment of acute cough was previously demonstrated in a randomized clinical trial. Here, we present real-life data from a pharmacy-based, observational study on the effectiveness and tolerability of another thyme/ivy combination (BNO 1200, Bronchipret drops).

METHODS

This observational, prospective, uncontrolled study was conducted in 305 German pharmacies. Cough and associated symptoms, cough severity and health related quality of life (HRQoL) were assessed at baseline, after 4 days and at individual end of treatment (EoT) in patients with acute cough due to upper respiratory tract infections who bought BNO 1200. Patients took BNO 1200 until resolution of cough and completed three validated questionnaires: patient-adapted Bronchitis Severity Score (BSS), cough severity visual analogue scale (VAS) and the Leicester Cough Questionnaire (LCQ-acute). They also rated speed of onset of treatment action on a VAS and tolerability.

RESULTS

A total of 749 patients participated in the study; 730 were included in the analysis. Mean treatment duration was 7.0 ± 3.6 days. Symptom severity assessed by BSS improved from 8.7 ± 3.8 score points (baseline) to 2.4 ± 2.6 at EoT (p < .0001). Clinically relevant improvements (MCID = 17 mm) in cough severity were reported by 87.2% of patients at EoT. HRQoL improved significantly (12.2 ± 3.3 points at baseline vs. 18.5 ± 2.7 at EoT; p < .0001), exceeding the MCID (=2 points) in 90.0% of patients. Tolerability was rated "good" or "very good" by 98.0% of patients. No adverse drug reactions were reported.

CONCLUSION

Patients with acute cough taking BNO 1200 had a significant reduction in BSS, cough severity and improvement in HRQoL confirming RCT data with the syrup formulation. BNO 1200 was well tolerated.

Effectiveness of Pelargonium sidoides in pediatric patients diagnosed with uncomplicated upper respiratory tract infection: a single-blind, randomized, placebo-controlled study

Upper respiratory tract infections (URTIs) are a condition characterized by upper airway inflammation often caused by viruses in humans. The present study aimed to assess the effectiveness of the liquid herbal drug preparation from the root extracts of Pelargonium sidoides in improving symptoms of uncomplicated URTIs. One hundred sixty-four patients with URTI were randomized and given either verum containing the root extracts of Pelargonium sidoides (n = 82) or a matching placebo (n = 82) in a single-blind manner for 7 days. The median total scores of all symptoms (TSS) showed a significant decreasing trend in the group treated with the root extracts derived from Pelargonium sidoides compared to the placebo group from day 0 to day 7 (TSS significantly decreased by 0.85 points in the root extract group compared to a decrease of 0.62 points, p = 0.018). "Cough frequency" showed a significant improvement from day 0 to day 3 (p = 0.023). There was also detected a significant recovery in "sneezing" on day 3 via Brunner-Langer model, and it was detected that the extract administration given in the first 24 h onset of the symptoms had provided a significant improvement in day 0 to day 3 (difference of TSS 0.18 point, p = 0.011).Conclusion: The findings of the study revealed that the Pelargonium sidoides extracts are effective in relieving the symptom burden in the duration of the disease. It may be regarded as an alternative option for the management of URTIs. What is Known: • Upper respiratory tract infections (URTIs), an inflammation on the upper airways, are the most common infectious disease in children. • Pelargonium sidoides, a traditional medicinal plant native to South Africa, is one of the ornamental geraniums that is thought to be effective in treating URTIs What is New: • It may be revealed that the dried root extract of Pelargonium sidoides compared with placebo might be an alternative treatment in improving the symptoms such as dry cough, sneezing, and relieving cough frequency. • The administration of the root extract at the onset of URTIs' signs may be regarded as an adjunctive option for the management of URTIs due to its effectiveness in decreasing the symptom burden of the disease.

Treatment of Urinary Tract Infections with Canephron® in Germany: A Retrospective Database Analysis

Objective: The goal of the present study was to evaluate treatment with Canephron^® compared to standard antibiotic treatment after diagnosis of acute cystitis or urinary tract infection (UTI), with regard to the risk of sporadic recurrent UTIs, frequent recurrent UTIs, UTI-related sick leave, additional antibiotic prescriptions, and renal complications (pyelonephritis). Methods: This retrospective cohort study was based on data from the IMS^® Disease Analyzer database (IQVIA), and included outpatients in Germany with at least one diagnosis of acute cystitis or UTI with a prescription of either Canephron^® or standard antibiotics between January 2016 and June 2019 and treated in general practitioner (GP), gynecologist, or urologist practices, from which the data were obtained. Multivariable regression models were used to investigate the association between Canephron^® prescription and the amount of sporadic or frequent recurrent UTIs, as well as the duration of UTI-related sick leave, the number of additional antibiotic prescriptions, and cases of pyelonephritis. The effects of Canephron^® were adjusted for age, sex, insurance status, and Charlson comorbidity score (CCI). Results: 2320 Canephron^® patients and 158,592 antibiotic patients were available for analysis. Compared to antibiotic prescription, Canephron^® prescription was significantly associated with fewer sporadic recurrences of UTI infections 30–365 days after the index date (odds ratio (OR): 0.66; 95%, confidence interval (CI): 0.58–0.72), as well as less frequent recurrences of UTI infections (OR: 0.61; 95% CI: 0.49–0.88), and also with reduced additional antibiotic prescription within 31–365 days (OR: 0.57; 95% CI: 0.52–0.63). No significant differences were observed between the Canephron^® and antibiotic cohorts with regard to the likelihood of sick leave (OR: 0.99; 95% CI: 0.86–1.14), new antibiotic prescription within 1–30 days (OR: 1.01; 95% CI: 0.87–1.16), or occurrence of pyelonephritis (Hazard Ratio (HR): 1.00; 95% CI: 0.67–1.48). Conclusion: These real-world data show that Canephron^® is an effective, safe symptomatic treatment for acute cystitis or UTI. It should be considered as an alternative treatment, particularly to also strengthen antimicrobial stewardship strategies.

Prevalence of and Factors Associated with Antibiotic Prescriptions in Patients with Acute Lower and Upper Respiratory Tract Infections-A Case-Control Study

Background: The goal of the present study was to estimate the prevalence of patient and physician related variables associated with antibiotic prescriptions in patients diagnosed with acute lower and upper respiratory tract infections (ALURTI), treated in general practices (GP) and pediatric practices, in Germany. Methods: The analysis included 1,140,095 adult individuals in 1237 general practices and 309,059 children and adolescents in 236 pediatric practices, from the Disease Analyzer database (IQVIA), who had received at least one diagnosis of an ALURTI between 1 January 2015 and 31 March 2019. We estimated the association between 35 predefined variables and antibiotic prescription using multivariate logistic regression models, separately for general and pediatric practices. The variables included the proportion (as a percentage) of antibiotics or phytopharmaceuticals on all prescriptions per practice, as an indicator of physician prescription preference. Results: The prevalence of antibiotic prescription was higher in patients treated in GP (31.2%) than in pediatric practices (9.1%). In GP, the strongest association with antibiotic prescription was seen in the practice preference for antibiotic use, followed by specific diagnoses (acute bronchitis, sinusitis, pharyngitis, laryngitis, and tracheitis), and higher patient age. In pediatric practices, acute sinusitis and bronchitis were the variables with the strongest association, followed by practice preference for antibiotic prescription. The strongest association with the non-prescription of antibiotics was practice preference for phytopharmaceuticals and the specific diagnosis of a viral infection. Conclusion: This study shows a high prevalence of antibiotic prescribing for patients with ALURTI in a primary care setting, especially in adult patients; physician related factors play an important role that should be addressed in interventions to reduce potentially inappropriate antibiotic prescribing.

The effects of Hedera helix on viral respiratory infections in humans: A rapid review

Brief overview

Based on the evidence identified in this rapid review, Hedera helix preparations and herbal complex preparations including H. helix may be a therapeutic option for treating early symptoms of respiratory tract infections. The best effectiveness for H. helix preparations has been proven for coughing, as an expectorant and to reduce the frequency and intensity of cough. Only weak evidence was found for all other researched symptoms. Both adults and children tolerate H. helix well. Currently, there is insufficient evidence to recommend the use of this supplement in the treatment or prevention of COVID-19. However, the current evidence justifies further research to better understand its applicability in coronavirus infections.

Verdic

tCurrent evidence suggests H. helix may improve the frequency and intensity of cough associated with viral respiratory infection. The overall applicability of additional findings is limited by the poorly defined outcome measures employed. However, studies focused explicitly on expectoration did report an increased conversion from dry to productive cough, and an improvement in expectoration amount, consistency and colour. These effects may be explained by a related finding of reduced oropharyngeal congestion and improved inflammatory markers (erythrocyte sedimentation rate and c-reactive protein). A decrease in frequency of night cough and respiratory pain was also reported, as was improved sleep quality and reduced cough-related sleep disturbance.

Some studies also measured general respiratory tract infection symptoms and identified clinical improvement or resolution of fever, fatigue, sore throat, sneezing, wheezing, nasal congestion, post-nasal drip and body-ache. A reduced need for antibiotic prescriptions was also identified. While not consistently reported, the majority of studies also found H. helix reduced the overall severity of viral bronchitis and related conditions. Tolerability was rated as between ‘good’ and ‘high’. Adverse events were rare or non-existent in almost all studies, and those that were reported were defined as non-serious and not drug-related.
