Congenital syphilis: A prospective study of 22 cases diagnosed by PCR.

Congenital syphilis (CS) is caused by Treponema pallidum infection in utero. There is a need to develop new tools to diagnose CS: the diagnostic value of PCR is difficult to assess. The aim of this study was to describe the clinical and laboratory characteristics of mothers and infants with CS as diagnosed by PCR tests on various maternal and neonatal samples. PATIENTS AND METHODS: We included all infants epidemiologically linked to a mother diagnosed with syphilis whose samples were referred to the Syphilis Reference Center, and for whom at least one positive PCR result was obtained. RESULTS: Twenty-two mother-infant pairs (8.3%) with assay performed on samples from one to four different anatomic sites were included between February 2011 and April 2018. Seven mothers (31.8%) were born abroad, fifteen (68.2%) presented psychological and/or social problems, eight (36.4%) had not been screened for syphilis prior to delivery, and eleven (50%) were referred from French overseas departments or territories, or from the Paris region. Six infants (27.3%) were stillborn and six were born preterm, while fifteen infants (68.2%) presented clinical features of CS. All infants born preterm were symptomatic. Infant VDRL/RPR titer was no greater than four times that in the mother's serum, except in two cases. DISCUSSION: Lack of antenatal care, social disadvantage and psychological issues were common. There is a need for enhanced surveillance both in the French overseas departments/territories and in the Paris region. A larger study is required to assess the sensitivity and specificity of PCR. The best site for sampling has yet to be established. We recommend the collection of as many samples as possible to avoid underdiagnosis of CS.

Observational study of anorectal Chlamydia trachomatis infections in France through the lymphogranuloma venereum surveillance network, 2010-2015.

The objective of this article is to describe the epidemiology of lymphogranuloma venereum (LGV) and non-LGV Chlamydia trachomatis anorectal infections in France and to examine the characteristics of the affected populations via a voluntary sentinel surveillance system for LGV between 2010 and 2015. Anorectal samples positive for C. trachomatis (CT) were sent by the participating laboratories to the National Reference Center for CT for LGV identification. Biological and clinical data were collected by biologists and clinicians. There were 1740 LGV episodes and 2248 non-LGV episodes. Continuous monitoring highlighted a sharp increase in the number of LGV and non-LGV anorectal infections, which were 2.3-fold and 6.5-fold, respectively. Most of the infections occurred in men who have sex with men. LGV patients were older than non-LGV patients and were more frequently human immunodeficiency virus (HIV)-positive compared to non-LGV patients. Anorectal LGV was significantly associated with residence in Paris, HIV co-infection, concurrent syphilis and bloody anal discharge. Undocumented patient characteristics were strongly associated with anorectal LGV. The anorectal LGV epidemic is poorly controlled in France. Early detection and prompt treatment of patients and their sexual partners are required to prevent transmission in the context of pre-exposure prophylaxis (PrEP) for HIV infection.

[Evaluation of factors associated with tuberculosis treatment default in Chad]. / Évaluation des facteurs associés aux abandons du traitement antituberculeux au Tchad.

INTRODUCTION: Tuberculosis (TB) treatment default contributes to the perpetuation of the epidemic and increases the risk of emergence of new forms of multidrug-resistant TB. The aim of this study was to identify the factors associated with treatment default in Chad. METHOD: This prospective study interviewed 286 patients with pulmonary TB in three centers, recruited at the beginning of treatment. We compared patients who completed the treatment to the treatment defaulters. A logistic regression model was fit to identify factors associated with default. RESULT: 32% of patients defaulted, that is, abandoned treatment. The multivariate analysis demonstrated that a low educational level and ignorance of the contagious nature of TB were associated with treatment interruption. CONCLUSION: TB education, patient assistance, and active tracing of patients who fail to return can help to prevent abandonment of TB treatment.

[Determinants of tuberculosis diagnosis delay in limited resources countries]. / Les déterminants du délai de diagnostic de la tuberculose dans les pays aux ressources limitées.

BACKGROUND: Delayed diagnoses of pulmonary tuberculosis contribute to the spread of the epidemic. METHODS: This study aims to identify risk factors associated with patient delay (from symptoms onset to the first visit), health system delay (from the first visit to the tuberculosis treatment initiation) and total delay (sum of the patient and the health system delay) in low income and high tuberculosis burden countries. A systematic literature review has been performed using the keywords: "tuberculosis"; "delay", care seeking"; "health care seeking behavior"; "diagnosis" and "treatment". Only quantitative studies showing delays for pulmonary tuberculosis adult cases were included in this review. RESULTS: Low income, gender, rural life, unemployment, ageing and misunderstanding the microbial cause of tuberculosis are associated with delayed diagnoses. Systemic factors including low health care coverage, patient expenditures and entry into the health system by consulting a traditional healer or a non-skilled professional delay the beginning of tuberculosis treatment. CONCLUSION: Delays can be used as indicators to evaluate tuberculosis control programs. Active case finding in the households of contagious patients can help to diminish diagnostic delays in low-income countries with high endemicity.
