“…The median age in our study was four years old, similar to the median age described in other Portuguese studies. 7,8 There has been a significant decrease in the number of salmonellosis in recent years worldwide 2 and our results concur with this data. Comparing our results with a previous retrospective descriptive study carried out in our pediatric department, between January 1999 and August 2003 (Jacinto et al, unpublished, presented as a poster in "IX Jornadas Nacionais de Infecciologia Pediátrica", Évora, 8 -11 October 2003) we saw an important reduction in the number of cases.…”

“…Between 1999 and 2003 there were 82 cases per year, in contrast with our findings of 11 cases per year. The reduction in incidence was also observed in the retrospective study by Almeida et al, 7 with an annual average of 43.6 cases (between 2005 -2009).…”

“…2). As mentioned in other Portuguese studies 7,8,10 and in the Jacinto et al study mentioned previously, the most isolated serotype was Salmonella Enteritidis, followed by Salmonella Typhimurium. The INSA Epidemiological Bulletin (2014 -2017) identified as the most frequent serotypes: Salmonella 4,5:i:-, followed by Salmonella Enteritidis and Salmonella Typhimurium, and reported an increase in Salmonella Enteritidis serotype between 2014 and 2017.…”

“…In the Almeida et al study, the ingestion of a potentially contaminated food was considered in 45.3% of cases. 7 Salmonellosis hospitalization was required in 58.7% of children, compared to 67.7% in the Jacinto et al study and 83.5% in the Almeida et al study. 7 The most frequent diagnosis was acute gastroenteritis (in 83.9%), as observed in 1999 -2003 (in 90%).…”

“…In this study, salmonellosis was slightly more frequent in males, as observed in other Portuguese retrospective studies. 7,8 Even though the majority of observed patients were Portuguese (81%), our hospital has a very high incidence of migrants, specially from African countries, some of them living with poor hygiene conditions, a known risk factor for this disease. We found no reference to birthplace in other Portuguese studies.…”

Salmonellosis in Children at a Portuguese Hospital: A Retrospective Study

et al. 2023

Introduction: Salmonellosis represents a considerable health, social and economic burden in both high- and low-income countries. Recently, in Portugal, most cases of Salmonella infections have been reported in children under 15 years of age. The main aim of this study was to characterize, from an epidemiological, microbiological, and clinical perspective, cases of Salmonella isolation among children.Material and Methods: The authors performed a descriptive study using retrospective analysis of cases of salmonellosis, in pediatric age, at a Portuguese Level II Hospital, between January 2015 and July 2020. Results: The population included a total of 63 children, of which 81% were Portuguese. Ethnicity was identified in 13 children, most of whom were African. The median age at diagnosis was four years old (3.5 - 9 years old). Despite the small number of cases per year in our study (11), one-third were severe enough to require hospitalization. Overall, 13% of patients were treated with antibiotics. In 63% of the isolates, serotype was identified: Salmonella Enteriditis (38%), Salmonella Typhimurium (22%), and Salmonella Typhi (3%). Antibiotic resistance rates were 19% for ampicillin and 6.4% for amoxicillinclavulanic acid and cotrimoxazole. No resistance to third-generation cephalosporins was found.Conclusion: Given the obtained results, we intend to improve knowledge on salmonellosis in Portugal and, consequently improve prevention strategies, treatment and its notification. Although the incidence of salmonellosis has been decreasing in recent years it is the second most frequent gastrointestinal infection in the European Union, contributing to significant rates of hospitalizations and use of antibiotics in Portugal.

Salmonella 1,4,[5],12:i:- is presently considered one of the major serovars responsible for human salmonellosis worldwide. Due to its recent emergence, studies assessing the demographic characterization and spatial epidemiology of salmonellosis 1,4,[5],12:i:- at local- or country-level are lacking. In this study, a analysis was conducted over a 10year period, from 2000 to the first quarter of 2011 at the Portuguese National Laboratory in Portugal mainland, with a total of 215 Salmonella 1,4,[5],12:i:- serotyped isolates obtained from human infections by a passive surveillance system. Data regarding source, year and month of sampling, gender, age, district and municipality of the patients were registered. Descriptive statistical analysis and a spatial scan statistic combined with a geographic information system were employed to characterize the epidemiology and identify spatial clusters. Results showed that most districts have reports of Salmonella 1,4,[5],12:i:-, with a higher number of cases at the Portuguese coastland, including districts like Porto (n=60, 27.9%), Lisboa (n=29, 13.5%) and Aveiro (n=28, 13.0%). An increased incidence was observed in the period from 2004 to 2011 and most infections occurred during May and October. Spatial analysis revealed 4 clusters of higher than expected infection rates. Three were located in the north of Portugal, including two at the coastland (Cluster 1 [RR=3.58, p≤0.001] and 4 [RR=10.42 p≤0.230]), and one at the countryside (Cluster 3 [RR=17.76, p≤0.001]). A larger cluster was detected involving the center and south of Portugal (Cluster 2 [RR=4.85, p≤0.001]). The present study was elaborated with data provided by a passive surveillance system, which may originate an underestimation of disease burden. However, this is the first report describing the incidence and the distribution of areas with higher risk of infection in Portugal, revealing that Salmonella 1,4,[5],12:i:- displayed a significant geographic clustering and these areas should be further evaluated to identify risk factors in order to establish prevention programs.

Salmonella enterica serovar Apeyeme is a rare pathogen that primarily affects poultry. However, there are limited data about this infection in humans. In this case, a 7-month-old infant presented with high-grade fever without diarrhea for 12 hours prior to admission. Upon admission, he developed seizures and was referred for further intervention. He was diagnosed with meningoencephalitis with complications of subdural effusion, empyema, and abscesses. Salmonella Apeyeme was found in cerebrospinal fluid culture, but no growth was detected in either blood or stool cultures. He was given meropenem, vancomycin, and ciprofloxacin, but later developed disseminated intravascular coagulation. His clinical condition deteriorated over time, and he died 18 days after admission. To conclude, Salmonella Apeyeme infection should be considered if a patient is diagnosed with meningoencephalitis and has a history of poultry exposure.
