Meta-Analysis
BACKGROUND
There has been an increasing resistance rate to tetracyclines, the first line treatment for cholera disease caused by V. cholera strains, worldwide. The aim of the present study was to determine the global status of resistance to this class of antibiotic among V. cholera isolates.
METHODS
For the study, electronic databases were searched using the appropriate keywords including: 'Vibrio', 'cholera', 'Vibrio cholerae', 'V. cholerae', 'resistance', 'antibiotic resistance', 'antibiotic susceptibility', 'antimicrobial resistance', 'antimicrobial susceptibility', 'tetracycline', and 'doxycycline'. Finally, after some exclusion, 52 studies from different countries were selected and included in the study and meta-analysis was performed on the collected data.
RESULTS
The average resistance rate for serogroup O1 to tetracycline and doxycycline was 50% and 28%, respectively (95% CI). A high level of heterogeneity (I > 50%, p-value < 0.05) was observed in the studies representing resistance to tetracycline and doxycycline in O1 and non-O1, non-O139 serogroups. The Begg's tests did not indicate the publication bias (p-value > 0.05). However, the Egger's tests showed some evidence of publication bias in the studies conducted on serogroup O1.
CONCLUSIONS
The results of the present study show that the overall resistance to tetracyclines is relatively high and prevalent among V. cholerae isolates, throughout the world. This highlights the necessity of performing standard antimicrobial susceptibility testing prior to treatment choice along with monitoring and management of antibiotic resistance patterns of V. cholerae strains in order to reduce the emergence and propagation of antibiotic resistant strains as well as the failure of treatment.

BACKGROUND
Posterior blepharitis is common and causes ocular surface and lid damage as well as discomfort. It affects 37% to 47% of all ophthalmology patients; its incidence increasing with age. It is a multifactorial disease associated with multiple other pathologies, such as rosacea, meibomianitis, and infections. Treatment usually focuses on reliefing the symptoms by using artificial tears, lid scrubs, and warm compresses. The condition may be notoriously difficult to manage adequately once it becomes chronic. One such management approach for chronic blepharitis is the use of oral antibiotics for both their antibacterial as well as anti-inflammatory properties. There are currently no guidelines regarding the use of oral antibiotics, including antibiotic type, dosage, and treatment duration, for the treatment of chronic blepharitis.
OBJECTIVES
To assess the benefits and harms of oral antibiotic use for people with chronic blepharitis.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2020, Issue 8); Ovid MEDLINE; Embase.com; PubMed; Latin American and Caribbean Health Sciences Literature Database (LILACS); ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). We did not use any date or language restrictions in the electronic search for trials. We last searched the electronic databases on 29 August 2020.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) comparing oral antibiotics with placebo in adult participants with chronic blepharitis (including staphylococcal, seborrhoeic, or Meibomian Gland Dysfunction (MGD)).
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methodology and graded the certainty of the body of evidence for six outcomes using the GRADE classification.
MAIN RESULTS
We included two studies with 220 participants (numbers of eyes unclear). One parallel-group RCT comparing oral doxycycline (40 mg once a day) with placebo enrolled 70 participants with blepharitis and facial rosacea in the USA. Follow-up duration was three months. One three-arm RCT conducted in South Korea investigated the effect of high-dose (200 mg twice a day) and low-dose (20 mg twice a day) doxycycline versus placebo after one month of study medication. It enrolled 50 participants with chronic MGD in each study arm (i.e. 150 participants enrolled in total). The two studies did not evaluate the same outcome measurements, which precluded any meta-analysis. The evidence for the effect of oral antibiotics on subjective improvement in symptoms was very uncertain. One study suggested that there was little to no effect of oral doxycycline on subjective symptoms based on the Ocular Surface Disease Index (OSDI) scores ranging from 0 to 100 (higher score indicates worse condition) (mean difference (MD) 3.55, 95% confidence interval (CI) -4.61 to 11.71; n = 70) and bulbar conjunctival hyperemia ranging from 0 (clear) to 4 (severe) (MD -0.01, 95% CI -0.38 to 0.36; n = 70) at 12 weeks. The three-arm RCT showed that oral doxycycline may slightly improve number of symptoms (MD -0.56, 95% CI -0.95 to -0.17; n = 93 (high-dose doxycycline versus placebo); MD -0.48, 95% CI -0.86 to -0.10; n = 93 (low-dose doxycycline versus placebo)) and proportion of participants with symptom improvement (risk ratio (RR) 6.13, 95% CI 2.61 to 14.42; n = 93 (high-dose doxycycline versus placebo); RR 6.54, 95% CI 2.79 to 15.30; n = 93 (low-dose doxycycline versus placebo)) at one month, but the evidence is very uncertain. We judged the certainty of evidence for subjective symptoms as very low. One study evaluated aqueous tear production by Schirmer's test (mm/5 min) (higher score indicates better condition) and tear film stability by measuring tear film break-up time (TBUT) in seconds (higher score indicates better condition) at one month. We found very low certainty evidence that oral doxycycline may improve these clinical signs. The estimated MD in Schirmer's test score after one month of treatment was 4.09 mm (95% CI 2.38 to 5.80; n = 93) in the high-dose doxycycline group versus the placebo group and 3.76 mm (95% CI 1.85 to 5.67; n = 93) in the low-dose doxycycline group versus the placebo group. The estimated MD in TBUT after one month was 1.58 seconds (95% CI 0.57 to 2.59; n = 93) when comparing the high-dose doxycycline group with the placebo group, and 1.70 seconds (95% CI 0.96 to 2.44; n = 93) when comparing the low-dose doxycycline group with the placebo group. Although there was a noted improvement in these scores, their clinical importance remains uncertain. One study suggested that oral doxycycline may increase the incidence of serious side effects: 18 (39%) participants in the high-dose doxycycline group, 8 (17%) in the low-dose doxycycline group, and 3 (6%) out of 47 participants in the placebo group experienced serious side effects (RR 6.13, 95% CI 1.94 to 19.41; n = 93 (high-dose doxycycline versus placebo); RR 2.72, 95% CI 0.77 to 9.64; n = 93 (low-dose doxycycline versus placebo)). Additionally, one study reported that one case of migraine headache and five cases of headache were observed in the oral doxycycline group, and one case of non-Hodgkin's lymphoma was observed in the placebo group. We judged the certainty of evidence for adverse events as very low.
AUTHORS' CONCLUSIONS
There was insufficient evidence to draw any meaningful conclusions on the use of oral antibiotics for chronic blepharitis. Very low certainty evidence suggests that oral antibiotics may improve clinical signs, but may cause more adverse events. The evidence for the effect of oral antibiotics on subjective symptoms is very uncertain. Further trials are needed to provide high quality evidence on the use of oral antibiotics in the treatment of chronic blepharitis.

BACKGROUND
Pulpal and periodontal healing are two main concerns of delayed replantation of avulsed teeth. The objective of this review was to evaluate the effectiveness of topical and systemic application of tetracyclines on pulpal and periodontal healing after tooth replantation.
METHODS
A comprehensive electronic search was conducted in six databases. This systematic review was carried out according to Cochrane Handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.
RESULTS
After exclusion of 246 irrelevant papers, 14 animal studies and one human study were included in this review. The human study showed that avulsed permanent teeth treated with doxycycline did not show a better clinical outcome for pulp and periodontal healing compared with treatment with normal saline. As for animal studies, significant more pulpal healing was observed in immature teeth treated with topical doxycycline in two researches, while another one study showed that there is no difference between teeth treated with normal saline and teeth treated with doxycycline. Systemic doxycycline exerted no significant effect on pulpal revascularization illustrated by one research. Only one out of four articles illustrated the positive effect of systemic tetracyclines on periodontal healing. One paper reported that intracanal application of demeclocycline promoted favorable periodontal healing. Two articles showed topical doxycycline contributed to favorable periodontal healing, while five studies showed no significant effect of topical tetracyclines on periodontal healing.
CONCLUSIONS
As a result of data heterogeneity and limitations of the studies, the effect of topical or systemic application of tetracyclines on pulpal and periodontal healing is inconclusive. More studies are required to get more clinically significant conclusions.

Antibiotic consumption is a key driver of antimicrobial resistance (AR), particularly in low- and middle-income countries (LMICs) where risk factors for AR emergence and spread are prevalent. However, the potential contribution of mass drug administration (MDA) and systematic drug administration (SDA) of antibiotics to AR spread is unknown. We conducted a systematic review to provide an overview of MDA/SDA in LMICs, including indications, antibiotics used and, if investigated, levels of AR over time. This systematic review is reported in accordance with the PRISMA statement. Of 2438 identified articles, 63 were reviewed: indications for MDA/SDA were various, and targeted populations were particularly vulnerable, including pregnant women, children, human immunodeficiency virus (HIV)-infected populations, and communities in outbreak settings. Available data suggest that MDA/SDA may lead to a significant increase in AR, especially following azithromycin administration. However, only 40% of studies evaluated AR. Integrative approaches that evaluate AR in addition to clinical outcomes are needed to understand the consequences of MDA/SDA implementation, combined with standardised AR surveillance for timely detection of AR emergence.

Orphanet Journal of Rare Diseases Apr 2021Hepatic Actinomycosis (HA) is one of the infections that causes disorders in patients when diagnosed untimely and inappropriately. (Review)
Review
BACKGROUND
Hepatic Actinomycosis (HA) is one of the infections that causes disorders in patients when diagnosed untimely and inappropriately.
METHODS
Case reports on HA in patients published between 2000 and April 2020 were gathered by carrying out a structured search through PubMed/Medline.
RESULTS
Through a survey of the Medline database, 130 studies were identified and then, 64 cases with HA were included in the final analysis. Asia had the largest share of cases with 37.5% (24 reports), followed by Europe and the Americas. Affected patients were predominantly males (64%) and the overall mortality rate was 1% with only one male patient in his 50 s dying. Nearly all patients (92%) were immunocompetent. However, in four patients, the use of immunosuppressive medication led to depression of the immune system. Most of the patients (80%) experienced complications. In terms of the complications, the most frequent ones were previous history of abdominal surgery (32%) and foreign bodies in the abdominopelvic region (20%). Actinomyces israelii was the most common pathogen isolated from patients. Abdominal pain (66%), fever (62%), weight loss (48%), night sweat, malaise, and anorexia (14%) over about 3.1 months were the most frequently reported clinical symptoms. Extension to one or more surrounding organs was evident in 18 patients (28%). Histopathologic examination confirmed infection in 67% of the patients and samples obtained from liver puncture biopsy (32%) were most frequently used in diagnosis. Surgery or puncture drainage + anti-infection was the most common method to treat patients and penicillin, Amoxicillin, Doxycycline, and ampicillin were the most frequently used drugs to control infection.
CONCLUSION
HA should be considered in patients with a subacute or chronic inflammatory process of the liver. With accurate and timely diagnosis of infection, extensive surgery can be prevented.

INTRODUCTION AND OBJECTIVE
Ivermectin (IVM) and doxycycline (DOXY) have demonstrated in-vitro activity against SARS-CoV-2, and have a reasonable safety profile. The objective of this systematic review was to explore the evidence in the literature on the safety and efficacy of their use as monotherapy and combination therapy in COVID-19 management.
METHODS
After prospectively registering the study protocol with the Open Science Framework, we searched PubMed, Google Scholar, clinicaltrials.gov, various pre-print servers and reference lists for relevant records published until 16 February, 2021 using appropriate search strategies. Baseline features and data pertaining to efficacy and safety outcomes were extracted separately for IVM monotherapy, DOXY monotherapy, and IVM + DOXY combination therapy. Methodological quality was assessed based on the study design.
RESULTS
Out of 200 articles screened, 19 studies (six retrospective cohort studies, seven randomised controlled trials, five non-randomised trials, one case series) with 8754 unique patients with multiple stages of COVID-19 were included; four were pre-prints and one was an unpublished clinicaltrials.gov document. The comparator was standard care and 'hydroxychloroquine + azithromycin' in seven and three studies respectively, and two studies were placebo controlled; six studies did not have a comparator. IVM monotherapy, DOXY monotherapy and IVM + DOXY were explored in eight, five and five studies, respectively; one study compared IVM monotherapy and IVM + DOXY with placebo. While all studies described efficacy, the safety profile was described in only six studies. Efficacy outcomes were mixed with some studies concluding in favour of the intervention and some studies displaying no significant benefit; barring one study that described 9/183 patients with erosive esophagitis and non-ulcer dyspepsia with IVM + DOXY (without causality assessment details), there were no new safety signals of concern with any of the three interventions considered. The quality of studies varied widely, with five studies having a 'good' methodological quality.
CONCLUSIONS
Evidence is not sufficiently strong to either promote or refute the efficacy of IVM, DOXY, or their combination in COVID-19 management.

Meta-Analysis
BACKGROUND
Osteoarthritis (OA) is common and burdensome for patients and health care systems. Our study purpose was to evaluate the long-term efficacy and safety of DMOADs in adults with knee and hip osteoarthritis.
METHODS
We searched Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and Web of Knowledge without language, publication, or date restrictions from inception through November 2018 for randomized controlled trials assessing 12 classes of DMOADs with at least 12 months of follow-up. Therapeutic effects were evaluated with pairwise and network meta-analysis. Outcomes included pain, function, minimum joint space width or cartilage volume, radiographic progression, and total joint replacement. Analyses were also performed for drug safety.
RESULTS
Twenty-eight randomized controlled trials with 11,890 patients were included. Glucosamine and chondroitin minimally improved both structure (minimum joint width or cartilage volume: network results: glucosamine: SMD 0.16; 95% CI [0.04, 0.28], chondroitin: SMD 0.21 [0.10, 0.32]) and symptoms (glucosamine: pain: - 0.15 [- 0.25, - 0.05]; function: - 0.17 [- 0.28, - 0.07], chondroitin: pain: - 0.06 [- 0.15, 0.03], and function: - 0.15 [- 0.26, - 0.03]). Strontium demonstrated improvement in structure (minimum joint width or cartilage volume: 0.20 [0.02, 0.38]), and vitamin D on symptoms (pain: - 0.15 [- 0.27, -0.03]; function: - 0.18 [- 0.31, - 0.06]). Although doxycycline also demonstrated a favorable efficacy ranking, its safety profile was poor (withdrawal: network relative risk 1.69 [1.03, 2.75]). The therapeutic effects of other medications were not ranked as highly.
DISCUSSION
Glucosamine and chondroitin yielded statistically significant but clinically questionable long-term benefit on structure and symptoms, though both had favorable safety profiles. Strontium improved structure, and vitamin D improved symptoms. Although doxycycline had a favorable efficacy ranking, its safety profile was poor. None of the 12 classes of drugs appears to have long-term clinically significant benefit.

Meta-Analysis
BACKGROUND
Chronic obstructive pulmonary disease (COPD) is a chronic respiratory condition characterised by persistent respiratory symptoms and airflow limitation. Acute exacerbations punctuate the natural history of COPD and are associated with increased morbidity and mortality and disease progression. Chronic airflow limitation is caused by a combination of small airways (bronchitis) and parenchymal destruction (emphysema), which can impact day-to-day activities and overall quality of life. In carefully selected patients with COPD, long-term, prophylactic use of antibiotics may reduce bacterial load, inflammation of the airways, and the frequency of exacerbations.
OBJECTIVES
To assess effects of different prophylactic antibiotics on exacerbations, quality of life, and serious adverse events in people with COPD in three separate network meta-analyses (NMAs), and to provide rankings of identified antibiotics.
SEARCH METHODS
To identify eligible randomised controlled trials (RCTs), we searched the Cochrane Airways Group Specialised Register of trials and clinical trials registries. We conducted the most recent search on 22 January 2020.
SELECTION CRITERIA
We included RCTs with a parallel design of at least 12 weeks' duration evaluating long-term administration of antibiotics prophylactically compared with other antibiotics, or placebo, for patients with COPD.
DATA COLLECTION AND ANALYSIS
This Cochrane Review collected and updated pair-wise data from two previous Cochrane Reviews. Searches were updated and additional studies included. We conducted three separate network meta-analyses (NMAs) within a Bayesian framework to assess three outcomes: exacerbations, quality of life, and serious adverse events. For quality of life, we collected data from St George's Respiratory Questionnaire (SGRQ). Using previously validated methods, we selected the simplest model that could adequately fit the data for every analysis. We used threshold analysis to indicate which results were robust to potential biases, taking into account each study's contributions to the overall results and network structure. Probability ranking was performed for each antibiotic class for exacerbations, quality of life, and serious adverse events.
MAIN RESULTS
Characteristics of studies and participants Eight trials were conducted at multiple sites that included hospital clinics or academic health centres. Seven were single-centre trials conducted in hospital clinics. Two trials did not report settings. Trials durations ranged from 12 to 52 weeks. Most participants had moderate to severe disease. Mean age ranged from 64 years to 73 years, and more males were recruited (51% to 100%). Forced expiratory volume in one second (FEV₁) ranged from 0.935 to 1.36 L. Most participants had previous exacerbations. Data from 12 studies were included in the NMAs (3405 participants; 16 treatment arms including placebo). Prophylactic antibiotics evaluated were macrolides (azithromycin and erythromycin), tetracyclines (doxycyclines), quinolones (moxifloxacin) and macrolides plus tetracyclines (roxithromycin plus doxycycline). Risk of bias and threshold analysis Most studies were at low risk across domains, except detection bias, for which only seven studies were judged at low risk. In the threshold analysis for exacerbations, all comparisons in which one antibiotic was compared with another were robust to sampling variation, especially macrolide comparisons. Comparisons of classes with placebo were sensitive to potential bias, especially macrolide versus placebo, therefore, any bias in the comparison was likely to favour the active class, so any adjustment would bring the estimated relative effect closer to the null value, thus quinolone may become the best class to prevent exacerbations. Exacerbations Nine studies were included (2732 participants) in this NMA (exacerbations analysed as time to first exacerbation or people with one or more exacerbations). Macrolides and quinolones reduced exacerbations. Macrolides had a greater effect in reducing exacerbations compared with placebo (macrolides: hazard ratio (HR) 0.67, 95% credible interval (CrI) 0.60 to 0.75; quinolones: HR 0.89, 95% CrI 0.75 to 1.04), resulting in 127 fewer people per 1000 experiencing exacerbations on macrolides. The difference in exacerbations between tetracyclines and placebo was uncertain (HR 1.29, 95% CrI 0.66 to 2.41). Macrolides ranked first (95% CrI first to second), with quinolones ranked second (95% CrI second to third). Tetracyclines ranked fourth, which was lower than placebo (ranked third). Contributing studies were considered as low risk of bias in a threshold analysis. Quality of life (SGRQ) Seven studies were included (2237 participants) in this NMA. SGRQ scores improved with macrolide treatment compared with placebo (fixed effect-fixed class effect: mean difference (MD) -2.30, 95% CrI -3.61 to -0.99), but the mean difference did not reach the minimally clinical important difference (MCID) of 4 points. Tetracyclines and quinolones did not improve quality of life any more than placebo, and we did not detect a difference between antibiotic classes. Serious adverse events Nine studies were included (3180 participants) in the NMA. Macrolides reduced the odds of a serious adverse event compared with placebo (fixed effect-fixed class effect: odds ratio (OR) 0.76, 95% CrI 0.62 to 0.93). There was probably little to no difference in the effect of quinolone compared with placebo or tetracycline plus macrolide compared with placebo. There was probably little to no difference in serious adverse events between quinolones or tetracycline plus macrolide. With macrolide treatment 49 fewer people per 1000 experienced a serious adverse event compared with those given placebo. Macrolides ranked first, followed by quinolones. Tetracycline did not rank better than placebo. Drug resistance Ten studies reported drug resistance. Results were not combined due to variation in outcome measures. All studies concluded that prophylactic antibiotic administration was associated with the development of antimicrobial resistance.
AUTHORS' CONCLUSIONS
This NMA evaluated the safety and efficacy of different antibiotics used prophylactically for COPD patients. Compared to placebo, prolonged administration of macrolides (ranked first) appeared beneficial in prolonging the time to next exacerbation, improving quality of life, and reducing serious adverse events. No clear benefits were associated with use of quinolones or tetracyclines. In addition, antibiotic resistance was a concern and could not be thoroughly assessed in this review. Given the trade-off between effectiveness, safety, and risk of antibiotic resistance, prophylactic administration of antibiotics may be best reserved for selected patients, such as those experiencing frequent exacerbations. However, none of the eligible studies excluded patients with previously isolated non-tuberculous mycobacteria, which would contraindicate prophylactic administration of antibiotics, due to the risk of developing resistant non-tuberculous mycobacteria.
