Abstract
INTRODUCTION Reaching the point of treatment failure in the management of pediatric acute otitis media (AOM) is decision-changing, and is often associated with switching to a broader coverage antibiotic with/without middle ear surgical drainage. Yet, still there is no consensus on the definition of what is treatment failure, which may lead to confusion for clinical decision-making purposes. We sought to review the heterogeneity of treatment failure definitions in AOM. METHODS We searched for relevant English language manuscripts using the following key-words: ['otitis media' (OM) or (AOM)] AND ['treatment failure' or 'failure' or 'response failure' or 'response'] AND 'human' in various electronic databases from 1/1/2005 through 10/31/2020. RESULTS In the 60 retrieved papers, treatment failure was considered only when antibiotics had been prescribed beforehand, but not when watchful waiting had been adopted. We categorized the manuscripts into 5 major treatment failure definition subgroups, which occasionally overlapped: unimprovement or worsening of symptoms or signs of failure in otoscopy (n = 36), specialist(s) referral or hospital admission (n = 12), changing or adding antibiotic treatment (n = 22), failure to eradicate causative bacteria (n = 7) and failure as perceived by parents (n = 4). CONCLUSIONS We suggest a broader definition of AOM treatment failure including physical examination findings and degree of initial treatment response, which will enable an unbiased, uniform comparison of treatments for pediatric AOM.

Substantial reduction of antibiotic-non-susceptible pneumococcal otitis media following PCV7/PCV13 sequential introduction. J Antimicrob Chemother 2020; 75:3038-3045. [PMID: 32946586 DOI: 10.1093/jac/dkaa263] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 05/11/2020] [Accepted: 05/14/2020] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND In the pre-pneumococcal conjugated vaccines (PCVs) era, serotypes included in the 7/13-valent PCVs (PCV7/PCV13) caused most pneumococcal otitis media (OM) and antibiotic-non-susceptible pneumococcal OM (ANSP-OM) episodes. In southern Israel, sequential PCV7/PCV13 introduction resulted in >90% reduction of vaccine-serotype OM. OBJECTIVES We assessed the dynamics of ANSP-OM necessitating middle ear fluid culture following PCV7/PCV13 sequential introduction in young children. METHODS This was a prospective, population-based, active surveillance. All episodes in children <3 years old, during 2004-16, were included. Two subperiods were defined: (i) pre-PCV: 2004-08; and (ii) PCV13: 2014-16. ANSP was defined for the following antibiotics: penicillin (MIC ≥0.1 mg/L and ≥1.0 mg/L), macrolide, tetracycline, clindamycin, ceftriaxone, trimethoprim/sulfamethoxazole and chloramphenicol. MDR was defined as ANSP for ≥3 classes. RESULTS Overall, 2270 pneumococcal OM episodes were identified. Annual overall pneumococcal, PCV13 and non-PCV13 serotype OM incidence declined by 86%, 97% and 33%, respectively, comparing pre-PCV with the PCV13 period. During 2004-08, 95% of ANSP was observed in vaccine serotypes. Incidence of penicillin (MIC ≥0.1 mg/L and ≥1.0 mg/L), macrolide, tetracycline, clindamycin, ceftriaxone and multidrug ANSP-OM declined by >90% in the PCV13 period. Rates of trimethoprim/sulfamethoxazole and chloramphenicol ANSP-OM declined by 85% and 79%, respectively. The proportions of ANSP of all pneumococcal isolates declined by ∼70% for penicillin, ceftriaxone and erythromycin; 53% for tetracycline; and 55% for MDR, versus no significant reductions observed for chloramphenicol, trimethoprim/sulfamethoxazole and clindamycin. CONCLUSIONS PCV7/PCV13 sequential introduction resulted in rapid and substantial ANSP-OM reduction, in parallel with the near disappearance of PCV13-serotype OM and no increase in replacement disease.

Clin Infect Dis 2020; 68:818-826. [PMID: 30032236 DOI: 10.1093/cid/ciy570] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2018] [Accepted: 07/18/2018] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Hospitalization rates for infectious diseases in New Zealand (NZ) children have increased since 1989. The highest burden is among Māori and Pacific children, and the most socioeconomically deprived. New Zealand introduced pneumococcal conjugate vaccine (PCV)7 in June 2008, PCV10 in 2011, and PCV13 in 2014. METHODS A retrospective cohort study of NZ children aged <6 years between 2006 and 2015 was performed using administrative databases. Demographics and hospitalizations were linked to evaluate the impact of the PCV vaccination program on cases of invasive pneumococcal disease (IPD), all-cause pneumonia (ACP), and otitis media (OM), defined by ICD-10-AM codes, and to explore the effect by ethnicity and deprivation. RESULTS Between 2006 and 2015, there were 640 children hospitalized with IPD, 26589 for ACP, and 44545 for OM. IPD hospitalizations declined by 73% between 2005 and 2015 for children <6 years of age, whereas ACP and OM declined by 8% and 25%, respectively. The highest rates for all diseases were among Māori and Pacific children and those from high deprivation. However, the declines were highest among Māori and Pacific children and those from socioeconomically deprived areas. IPD hospitalizations declined by 79% and 67% for Māori and Pacific children, respectively, between 2006 and 2015. ACP declined by 12% in Māori and 21% in Pacific children. OM declined by 51% in Māori children. CONCLUSION In contrast to the increasing trend of hospitalization rates for infectious disease in New Zealand, the use of PCV appears associated with reductions in ethnic and socioeconomic disparities in hospitalization for IPD, ACP, and OM.

Impact of the 10-valent pneumococcal conjugate vaccine on hospital admissions in children under three years of age in Iceland. Vaccine 2020; 38:2707-2714. [PMID: 32063434 DOI: 10.1016/j.vaccine.2020.01.094] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2018] [Revised: 01/28/2020] [Accepted: 01/30/2020] [Indexed: 01/07/2023]
Abstract
INTRODUCTION Pneumococcus is an important respiratory pathogen. The 10-valent pneumococcal vaccine (PHiD-CV) was introduced into the Icelandic vaccination programme in 2011. The aim was to estimate the impact of PHiD-CV on paediatric hospitalisations for respiratory tract infections and invasive disease. METHODS The 2005-2015 birth-cohorts were followed until three years of age and hospitalisations were recorded for invasive pneumococcal disease (IPD), meningitis, sepsis, pneumonia and otitis media. Hospitalisations for upper- and lower respiratory tract infections (URTI, LRTI) were used as comparators. The 2005-2010 birth-cohorts were defined as vaccine non-eligible cohorts (VNEC) and 2011-2015 birth-cohorts as vaccine eligible cohorts (VEC). Incidence rates (IR) were estimated for diagnoses, birth-cohorts and age groups, and incidence rate ratios (IRR) between VNEC and VEC were calculated assuming Poisson variance. Cox regression was used to estimate the hazard ratio (HR) of hospitalisation between VNEC and VEC. RESULTS 51,264 children were followed for 142,315 person-years, accumulating 1,703 hospitalisations for the respective study diagnoses. Hospitalisations for pneumonia decreased by 20% (HR 0.80, 95%CI:0.67-0.95) despite a 32% increase in admissions for LRTI (HR 1.32, 95%CI:1.14-1.53). Hospital admissions for culture-confirmed IPD decreased by 93% (HR 0.07, 95%CI:0.01-0.50) and no hospitalisations for IPD with vaccine-type pneumococci were observed in the VEC. Hospitalisations for meningitis and sepsis did not change. A decrease in hospital admissions for otitis media was observed, but did not coincide with PHiD-CV introduction. CONCLUSION Following the introduction of PHiD-CV in Iceland, hospitalisations for pneumonia and culture confirmed IPD decreased. Admissions for other LRTIs and URTIs increased during this period.

Updated Guidelines for the Management of Acute Otitis Media in Children by the Italian Society of Pediatrics: Prevention. Pediatr Infect Dis J 2019; 38:S22-S36. [PMID: 31876602 DOI: 10.1097/inf.0000000000002430] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/19/2022]
Abstract
BACKGROUND In recent years, new information has been acquired regarding the diagnosis, treatment and prevention of acute otitis media (AOM). The Italian Pediatric Society, therefore, decided to issue an update to the Italian Pediatric Society guidelines published in 2010. METHODS The search was conducted on Pubmed, and only those studies regarding the pediatric age alone, in English or Italian, published between January 1, 2010 and December 31, 2018, were included. Each study included in the review was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methodology. The quality of the systematic reviews was evaluated using the A MeaSurement Tool to Assess systematic Reviews (AMSTAR) 2 appraisal tool. The guidelines were formulated using the GRADE methodology by a multidisciplinary panel of experts. RESULTS The importance of eliminating risk factors (passive smoking, environmental pollution, use of pacifier, obesity, limitation of day-care center attendance) and the promotion of breastfeeding and hygiene practices (nasal lavages) was confirmed. The importance of pneumococcal vaccination in the prevention of AOM was reiterated with regard to the prevention of both the first episode of AOM and recurrences. Grommets can be inserted in selected cases of recurrent AOM that did not respond to all other prevention strategies. Antibiotic prophylaxis is not recommended for the prevention of recurrent AOM, except in certain carefully selected cases. The use of complementary therapies, probiotics, xylitol and vitamin D is not recommended. CONCLUSIONS The prevention of episodes of AOM requires the elimination of risk factors and pneumococcal and influenza vaccination. The use of other products such as probiotics and vitamin D is not supported by adequate evidence.

Abstract
Introduction: The introduction of 7-valent pneumococcal conjugate vaccine (PCV7) in childhood immunization programs reduced antimicrobial-resistant pneumococcal infections by vaccine serotypes. However, emerging antimicrobial-resistant non-vaccine serotypes, particularly serotype 19A, attenuated the overall effect. In 2010, higher-valent PCVs became available containing serotypes that are prone to become antimicrobial-resistant, like serotype 7F in PCV10 and PCV13, and serotype 19A in PCV13.Areas covered: This review evaluated literature published between June 1, 2008 and June 1, 2017 reporting on the effect of PCV10 or PCV13 implementation in routine infant immunization schedules on antimicrobial-resistant invasive pneumococcal disease (IPD), otitis media (OM), and nasopharyngeal carriage (NPC) in children and adults.Expert opinion: In countries with relatively high prior pneumococcal antimicrobial resistance (AMR), PCV13 childhood vaccination programs have reduced antimicrobial-resistant IPD, OM, and NPC in children and IPD in adults. The effectiveness of PCV13 against serotype 19A is likely an important contributing factor. Only few studies have documented the impact of PCV10 on AMR. Multiple factors may influence observed decreases in pneumococcal AMR including antimicrobial stewardship, case definition, time since PCV10/13 introduction, and pre-PCV10/13 AMR levels. This review emphasizes the importance of including impact on AMR when evaluating the full public health of pneumococcal vaccination programs.
