- Health worker recommended vaccination rates among medical students in Brazil(2021) LEME, Mateus Deckers; GILIO, Alfredo EliasHealth workers are a risk population for many infectious diseases, which leads to a number of vaccines being routinely recommended for health care staff. Medical students are also prone to such hazards. This study accesses undergraduate medicine students' compliance to recommended health-staff vaccination, and their reasons for noncompliance. Method: An online questionnaire was sent to all undergraduates in a major public medical school in Brazil, asking about vaccination status to Hepatitis B, Measle-mumps-rubella, Varicella, Pertussis and Influenza, and reasons in case of noncompliance Results: 146 students answered the questionnaire, (response rate 14,6%). Overall vaccination status showed 74,7% of students with incomplete vaccination in some way, with an increase in vaccination status toward the end of the course. The highest noncompliance rates were Pertussis (49,3%), Varicella (47,3%) and Influenza (30,1%) vaccines. The vaccine with the lowest noncompliance rate was measles (9,6%). During the course, the greatest increases in adequate vaccination status were Hepatitis B, from 53,2% in first-years to 93,2% by the end sixth year (chi-sq 21, p < 0,0001), and Influenza, from 48,9% to 91,5% (chi-sq 22,5, p < 0,00009). Main reasons given not to vaccinate were vaccination hesitancy for influenza and varicella (respectively 61% and 46%), and lack of awareness of the need to vaccinate for pertussis (53%). Conclusions: Overall vaccine coverage in medical students in Brazil is still far from optimal. There is a markedly high level of vaccine hesitancy and unawareness of need to vaccinate for some diseases, particularly pertussis and influenza. (C) 2021 Published by Elsevier Ltd.
- Chronic medical conditions associated with invasive pneumococcal diseases in inpatients in teaching hospitals in Sao Paulo city: Estimating antimicrobial susceptibility and serotype-coverage of pneumococcal vaccines(2023) KFOURI, Renato A.; BRANDILEONE, Maria-Cristina C.; SAFADI, Marco Aurelio P.; RICHTMANN, Rosana; GILIO, Alfredo E.; ROSSI, Flavia; GUIMARAES, Thais; BIERRENBACH, Ana Luiza; MORAES, Jose C.; IPD, Sao Paulo Study Grp I. P. D. Sa Paulo Study GrpBackground: Chronic conditions increase the risk of invasive pneumococcal diseases (IPD). Pneumococcal vaccination remarkably reduced IPD morbimortality in vulnerable popula-tions. In Brazil, pneumococcal vaccines are included in the National Immunization Pro-gram (PNI): PCV10 for < 2 years-old, and PPV23 for high risk-patients aged >= 2 years and institutionalized >= 60 years. PCV13 is available in private clinics and recommended in the PNI for individuals with certain underlying conditions. Methods: A retrospective study was performed using clinical data from all inpatients from five hospitals with IPD from 2016 to 2018 and the corresponding data on serotype and antimicro-bial-non-susceptibility of pneumococcus. Vaccine-serotype-coverage was estimated. Patients were classified according to presence of comorbidities: healthy, without comorbidities; at-risk, included immunocompetent persons with specific medical conditions; high-risk, with immu-nocompromising conditions and others Results: 406 IPD cases were evaluated. Among 324 cases with information on medical condi-tions, children < 5 years were mostly healthy (55.9%), while presence of comorbidity pre-vailed in adults >= 18 years old (> 82.0%). Presence of >= 1 risk condition was reported in >= 34.8% of adults. High-risk conditions were more frequent than at-risk in all age groups. Among high-risk comorbidity (n = 211), cancer (28%), HIV/AIDS (25.7%) and hematological dis-eases (24.5%) were the most frequent. Among at-risk conditions (n = 89), asthma (16.5%) and diabetes (8.1%) were the most frequent. Among 404 isolates, 42.9% belonged to five serotypes: 19A (14.1%), 3 (8.7%), 6C (7.7%), 4 and 8 (6.2% each); 19A and 6C expressed antimicrobial-non -susceptibility. The vaccine-serotype-coverage was: PCV10, 19.1%, PCV13, 43.8%; PCV15, 47.8%; PCV20, 62.9%; PCV21, 65.8%, and PPV23, 67.3%. Information on hospital outcome was available for 283 patients, of which 28.6% died. Mortality was 54.2% for those with meningitis. Conclusion: Vaccine with expanded valence of serotypes is necessary to offer broad preven-tion to IPD. The present data contribute to pneumococcal vaccination public health policies for vulnerable patients, mainly those with comorbidity and the elderly. (c) 2023 Sociedade Brasileira de Infectologia.

- Clinical and laboratory features of urinary tract infections in young infants(2018) LO, Denise Swei; RODRIGUES, Larissa; KOCH, Vera Hermina Kalika; GILIO, Alfredo EliasABSTRACT Introduction: Urinary tract infection (UTI) is the most common serious bacterial infection in young infants. Signs and symptoms are often nonspecific. Objectives: To describe clinical, demographic and laboratory features of UTI in infants ≤ 3 months old. Methods: Cross-sectional study of infants ≤ 3 months old with UTI diagnosed in a pediatric emergency department, for the period 2010-2012. UTI was defined as ≥ 50,000 colony-forming units per milliliter of a single uropathogen isolated from bladder catheterization. Paired urinalysis and urine culture from group culture-positive and group culture-negative were used to determine the sensitivity and specificity of pyuria and nitrite tests in detecting UTI. Results: Of 519 urine cultures collected, UTI was diagnosed in 65 cases (prevalence: 12.5%); with male predominance (77%). The most common etiologies were Escherichia coli (56.9%), Klebsiella pneumoniae (18.5%) and Enterococcus faecalis (7.7%). Frequent clinical manifestations were fever (77.8%), irritability (41.4%) and vomiting (25.4%). The median temperature was 38.7°C. The sensitivity of the nitrite test was 30.8% (95%CI:19.9-43.4%), specificity of 100% (95%CI:99.2-100%). Pyuria ≥ 10,000/mL had a sensitivity of 87.7% (95%CI:77.2-94.5%), specificity of 74.9% (95%CI:70.6 -78.8%). The median peripheral white blood cell count was 13,150/mm3; C-reactive protein levels were normal in 30.5% of cases. Conclusions: The male: female ratio for urinary tract infection was 3.3:1. Non-Escherichia coli etiologies should be considered in empirical treatment. Fever was the main symptom. Positive nitrite is highly suggestive of UTI but has low sensitivity; whereas pyuria ≥ 10,000/mL revealed good sensitivity, but low specificity. Peripheral white blood cell count and C-reactive protein concentration have limited usefulness to suggest UTI.
- Respiratory viral infections in infants with clinically suspected pertussis(2013) FERRONATO, Angela E.; GILIO, Alfredo E.; VIEIRA, Sandra E.Objective: to evaluate the frequency of respiratory viral infections in hospitalized infants with clinical suspicion of pertussis, and to analyze their characteristics at hospital admission and clinical outcomes. Methods: a historical cohort study was performed in a reference service for pertussis, in which the research of respiratory viruses was also a routine for infants hospitalized with respiratory problems. All infants reported as suspected cases of pertussis were included. Tests for Bordetella pertussis (BP) (polymerase chain reaction/culture) and for respiratory viruses (RVs) (immunofluorescence) were performed. Patients who received macrolides before hospitalization were excluded. Clinical data were obtained from medical records. Results: among the 67 patients studied, BP tests were positive in 44%, and 26% were positive for RV. There was no etiological identification in 35%, and RV combined with BP was identified in 5%. All patients had similar demographic characteristics. Cough followed by inspiratory stridor or cyanosis was a strong predictor of pertussis, as well as prominent leukocytosis and lymphocytosis. Rhinorrhea and dyspnea were more frequent in viral infections. Macrolides were discontinued in 40% of patients who tested positive for RV and negative for BP. Conclusion: the results suggest that viral infection can be present in hospitalized infants with clinical suspicion of pertussis, and etiological tests may enable a reduction in the use of macrolides in some cases. However, the etiological diagnosis of respiratory virus infection, by itself, does not exclude the possibility of infection with BP.
- Impacto do uso da prova rápida para estreptococo beta-hemolítico do grupo A no diagnóstico e tratamento da faringotonsilite aguda em pronto-socorro de Pediatria(2013) CARDOSO, Débora Morais; GILIO, Alfredo Elias; HSIN, Shieh Huei; MACHADO, Beatriz Marcondes; PAULIS, Milena De; LOTUFO, João Paulo B.; MARTINEZ, Marina Baquerizo; GRISI, Sandra Josefina E.OBJECTIVE: To evaluate the impact of the routine use of rapid antigen detection test in the diagnosis and treatment of acute pharyngotonsillitis in children. METHODS: This is a prospective and observational study, with a protocol compliance design established at the Emergency Unit of the University Hospital of Universidade de São Paulo for the care of children and adolescents diagnosed with acute pharyngitis. RESULTS: 650 children and adolescents were enrolled. Based on clinical findings, antibiotics would be prescribed for 389 patients (59.8%); using the rapid antigen detection test, they were prescribed for 286 patients (44.0%). Among the 261 children who would not have received antibiotics based on the clinical evaluation, 111 (42.5%) had positive rapid antigen detection test. The diagnosis based only on clinical evaluation showed 61.1% sensitivity, 47.7% specificity, 44.9% positive predictive value, and 57.5% negative predictive value. CONCLUSIONS: The clinical diagnosis of streptococcal pharyngotonsillitis had low sensitivity and specificity. The routine use of rapid antigen detection test led to the reduction of antibiotic use and the identification of a risk group for complications of streptococcal infection, since 42.5% positive rapid antigen detection test patients would not have received antibiotics based only on clinical diagnosis.
- Analysis of invasive pneumonia-causing strains of Streptococcus pneumoniae: serotypes and antimicrobial susceptibility(2011) YOSHIOKA, Cristina R. M.; MARTINEZ, Marina B.; BRANDILEONE, Maria C. C.; RAGAZZI, Selma B.; GUERRA, Maria L. L. S.; SANTOS, Silvia R.; SHIEH, Huei H.; GILIO, Alfredo E.Objectives: To identify the most common pneumococcal serotypes in children hospitalized with invasive pneumonia, correlate isolated serotypes with those included in conjugate vaccines, and ascertain the sensitivity of the isolated pneumococcal strains to penicillin and other antibiotics. Methods: From January 2003 to October 2008, a retrospective study of hospitalized children with a diagnosis of Streptococcus pneumoniae pneumonia was conducted at the university hospital of Universidade de Sao Paulo. Criteria for inclusion were: age greater than 29 days and less than 15 years, radiological and clinical diagnosis of pneumonia, and isolation of Streptococcus pneumoniae in blood cultures and/or pleural effusion. Results: The study included 107 children. The most common serotypes were 14 (36.5%), 1 (16%), 5 (14.6%), 6B (6.3%) and 3 (4.2%). The proportion of identified serotypes contained in the heptavalent, 10-valent and 13-valent conjugate vaccines was 53.1, 86.5, and 96.9%, respectively. Pneumococcal strains were sensitive to penicillin (minimum inhibitory concentration, MIC <= 2 mu g/mL) in 100 cases (93.5%) and displayed intermediate resistance (MIC = 4 mu g/mL) in 7 cases (6.5%). No strains were penicillin-resistant (MIC >= 8 mu g/mL) according to the Clinical and Laboratory Standards Institute 2008 standards. Tested isolates were highly sensitive to vancomycin, rifampicin, ceftriaxone, clindamycin, erythromycin, and chloramphenicol. Conclusions: Our results confirm a significant potential impact of conjugate vaccines, mainly 10-valent and 13-valent, on invasive pneumonia. Furthermore, susceptibility testing results show that penicillin is still the treatment of choice for invasive pneumonia in our setting.
- The impact of varicella vaccination on varicella-related hospitalization rates: global data review(2016) HIROSE, Maki; GILIO, Alfredo Elias; FERRONATO, Angela Esposito; RAGAZZI, Selma Lopes BettaAbstract Objective: To describe the impact of varicella vaccination on varicella-related hospitalization rates in countries that implemented universal vaccination against the disease. Data source: We identified countries that implemented universal vaccination against varicella at the http://apps.who.int/immunization_monitoring/globalsummary/schedules site of the World Health Organization and selected articles in Pubmed describing the changes (pre/post-vaccination) in the varicella-related hospitalization rates in these countries, using the Keywords ""varicella"", ""vaccination/vaccine"" and ""children"" (or) ""hospitalization"". Publications in English published between January 1995 and May 2015 were included. Data synthesis: 24 countries with universal vaccination against varicella and 28 articles describing the impact of the vaccine on varicella-associated hospitalizations rates in seven countries were identified. The US had 81.4%–99.2% reduction in hospitalization rates in children younger than four years, 6–14 years after the onset of universal vaccination (1995), with vaccination coverage of 90%; Uruguay: 94% decrease (children aged 1–4 years) in six years, vaccination coverage of 90%; Canada: 93% decrease (age 1–4 years) in 10 years, coverage of 93%; Germany: 62.4% decrease (age 1–4 years) in 8 years, coverage of 78.2%; Australia: 76.8% decrease (age 1–4 years) in 5 years, coverage of 90%; Spain: 83.5% decrease (age <5 years) in four years, coverage of 77.2% and Italy 69.7%–73.8% decrease (general population), coverage of 60%–95%. Conclusions: The publications showed variations in the percentage of decrease in varicella-related hospitalization rates after universal vaccination in the assessed countries; the results probably depend on the time since the implementation of universal vaccination, differences in the studied age group, hospital admission criteria, vaccination coverage and strategy, which does not allow direct comparison between data.
- The impact of rotavirus vaccination on emergency department visits and hospital admissions for acute diarrhea in children under 5 years(2016) PAULO, Rodrigo Locatelli Pedro; RODRIGUES, Andre Broggin Dutra; MACHADO, Beatriz Marcondes; GILIO, Alfredo EliasIntroduction: Acute diarrheal disease is the second cause of death in children under 5 years. In Brazil, from 2003 to 2009, acute diarrhea was responsible for nearly 100,000 hospital admissions per year and 4% of the deaths in children under 5 years. Rotavirus is the leading cause of severe acute diarrhea worldwide. In 2006, the rotavirus monovalent vaccine (RV1) was added to the Brazilian National Immunization Program. Objectives: To analyze the impact of the RV1 on emergency department (ED) visits and hospital admissions for acute diarrhea. Method: A retrospective ecologic study at the University Hospital, University of Sao Paulo. The study analyzed the pre-vaccine (2003-2005) and the post-vaccine (2007-2009) periods. We screened the main diagnosis of all ED attendances and hospital admissions of children under 5 years in an electronic registry system database and calculated the rates of ED visits and hospital admissions. The reduction rate was analyzed according to the following formula: reduction (%) = (1 - odds ratio) x 100. Results: The rates of ED visits for acute diarrhea was 85.8 and 80.9 per 1,000 total ED visits in the pre and post vaccination periods, respectively, resulting in 6% reduction (95CI 4 to 9%, p<0.001). The rates of hospital admissions for acute diarrhea was 40.8 per 1,000 in the pre-vaccine period and dropped to 24.9 per 1,000 hospitalizations, resulting in 40% reduction (95CI 22 to 54%, p< 0.001). Conclusion: The introduction of the RV1 vaccine resulted in 6% reduction in the ED visits and 40% reduction in hospital admissions for acute diarrhea.
- A study of acceptance and hesitation factors towards tetanus, diphtheria, and acellular pertussis (Tdap) and influenza vaccines during pregnancy(2023) QUILES, Raquel; LEME, Mateus Deckers; LO, Denise Swei; GILIO, Alfredo EliasIntroduction: Vaccination of pregnant women with tetanus, diphtheria, and acellular pertussis (Tdap) and influenza vaccines is desirable to reduce neonatal and maternal morbidity and mortality. However, vaccine coverage rates and acceptance are frequently below recommended rates.Objectives: To ascertain Tdap and influenza vaccine coverage rates in our population and to study the reasons behind sub-optimal rates.Method: A survey was submitted to pregnant or in their puerperium women at the University Hospital of Sa & SIM;o Paulo University. Data were obtained during two consecutive influenza seasons (2017-2018), and vaccination was verified through vaccination chart checking. Respondents were classified according to their status as ""Received Tdap"" and ""Didn't receive Tdap"", and as ""Know"" or ""Doesn't know"" regarding their awareness of Tdap safety during pregnancy and protective effect on the newborn. Vaccine uptake and personal awareness of vaccination status were compared among these groups for Tdap and influenza vaccines.Results: In a studied sample of 207 patients (representative of the whole), coverage rates for Tdap and influenza vaccines were respectively 85.5% and 95.2%. Additionally, 84.5% received both vaccines. There was no vaccine refusal for Tdap and only 0.5% for influenza. For either Tdap or influenza vaccines, the main reason for not vaccinating was a lack of knowledge/information. Factors associated with not vaccinating Tdap during pregnancy were lower number of prenatal visits, being unemployed or freelance worker, not being aware of vaccine safety or its benefits for the baby, not being oriented by the doctor to be vaccinated, not being aware of personal vaccination status, and not having been vaccinated for influenza.Conclusion: While influenza vaccination coverage during pregnancy was ideal, Tdap rates were below recommended values. Significant factors associated with better coverage for Tdap during pregnancy included being employed and not being self-employed, (not yet reported in the Americas) and being aware of personal vaccination status.
