LATE DIAGNOSIS OF CONGENITAL SYPHILIS: A RECURRING REALITY IN WOMEN AND CHILDREN HEALTH CARE IN BRAZIL

Syphilitic hepatitis in infants, the forgotten disease that hepatologists have to brush up on: from a case series to a revision of literature

Clinical manifestations of congenital syphilis (CS) include liver disease with/without impaired liver function, identified as syphilitic hepatitis. Hepatic involvement may be dramatic; therefore, early diagnosis is crucial to provide treatment and prevent fatal outcomes. A new resurgence of CS cases has been described in recent years worldwide. We reported our experience with a case series of infants hospitalized for liver disease with a final diagnosis of CS, highlighting the wide spectrum of liver involvement, the rapid progression in cases with late diagnosis, and the pitfalls of the management of this forgotten but reemerging disease. A retrospective analysis of CS patients with hepatic presentation in the period 2008-2023 was conducted. We collected five cases (three female) with a median age of 13.8 days (range 1-84 days). In three cases, mothers were not screened for syphilis during pregnancy, and in two cases, they were seronegative in the first trimester screening. None practiced specific therapy during pregnancy. Hepatic involvement was characterized by hepatosplenomegaly, in four cases associated with cholestatic jaundice and in three cases with liver failure. Rapid plasma reagin (RPR) and Treponema pallidum hemagglutination assay (TPHA) were positive in all cases in mothers and infants. CS presented with multiorgan involvement and was fatal in one case.Conclusions: It is important to consider CS in infants with cholestasis and acute liver failure, but also in sick infants with isolated hepatomegaly. Early recognition of infants with CS is critical to identify missed cases during pregnancy and to start early treatment.

Factors influencing the positivity of diagnostic tests for congenital syphilis

OBJECTIVE

The objective of this study was to analyze the factors that influence the positivity of treponemal and non-treponemal tests in cases of congenital syphilis.

METHODS

This cross-sectional and correlational study was carried out from the analysis of the database of Disease and Notification Information System (SINAN, in Portuguese) using the data obtained through the Epidemiological Surveillance Group 29, with 639 notifications of congenital syphilis between 2007 and 2018. The data were analyzed by a descriptive and inferential analysis from logistic regression with a significance level of 5% (p≤0.05).

RESULTS

The positivity of the treponemal test was higher by 4.5 times in infants living in rural areas and 19.6 times among those whose mothers obtained the diagnosis of syphilis after birth. The treponemal test showed positivity 3.2 times higher for the variable "having been diagnosed between 2007 and 2015" and 5.5 times higher for the variable "having been diagnosed with maternal syphilis in the postpartum period."

CONCLUSION

This study shows that testing during prenatal care is essential for early diagnosis and prevention of syphilis complications.

CONGENITAL SYPHILIS IN THE PARAÍBA VALLEY USING A SPATIAL APPROACH

Objective:

To compare spatial patterns of congenital syphilis (CS) with those of socioeconomic and medical variables in Paraíba Valley, São Paulo, between 2012 and 2016.

Methods:

Ecological and exploratory study developed using spatial analysis tools, with information on CS cases obtained from official data reports. Rates were found for CS cases per 1,000 live births, number of family health teams and pediatricians available in the health system per 100,000 inhabitants, and social vulnerability index values. Thematic maps were constructed with these variables and compared using TerraView 4.2.2 software. Estimated global Moran (I_M) indexes were calculated. In order to detect areas with priority attention regarding the incidence of CS, BoxMaps were developed. The Spearman correlation was estimated for the variable values and compared using the Kruskal-Wallis test. P <0.05 was significant.

Results:

144,613 births and 870 CS cases (6.04/1000 live births) occurred during the study period. The average value of CS rates per municipality was 4.0±4.1, (0.0-17.6/1000 live births). Higher CS rates occurred in municipalities of the Upper Vale do Paraíba, contrary to the proportions of pediatricians who were in the far east of the region. The thematic maps of the variables presented a mosaic aspect, which characterized the random distribution of the variables. The I_M were not significant. No significant correlation was found between the variables. The BoxMap identified eight municipalities with high CS rates.

Conclusions:

Even though it was not possible to identify a spatial pattern of CS rates, it was shown that eight municipalities deserve the attention of city managers.

Case Report: A Delayed Diagnosis of Congenital Syphilis-Too Many Missed Opportunities

Congenital syphilis remains a significant public health problem nowadays. We describe the presentation of an infant with a delayed diagnosis of congenital syphilis, with a negative initial non-treponemal test. Our aim is to shed light on the incidence of missed prevention, the importance of awareness, maternal screening, and early diagnosis.
