Intact Mycobacterium leprae Isolated from Placenta of a Pregnant Woman, China.

Whether Mycobacterium leprae transmits from placenta to fetus remains unknown. We describe the case of a pregnant woman with untreated histoid leproma. Although her newborn was healthy, laboratory examination revealed intact M. leprae present in the placenta, suggesting that the placental barrier might prevent vertical dissemination of M. leprae.

Characteristics of pregnant and lactating women with leprosy.

INTRODUCTION: The clinical characteristics of women who conceive during leprosy and the association between leprosy and pregnancy are not well known. METHODS: This cross-sectional study included 49 pregnant or lactating women diagnosed with leprosy in 2011. RESULTS: The patients had a clinical dimorphous form of leprosy (44.9%), no physical incapacity at diagnosis (87.5%), and no complications in either the patient or infant (33.4%). In 36.3% of cases, leprosy symptoms were presented in the last trimester of pregnancy, and in 31.9% of patients were in the first trimester of lactation. CONCLUSIONS: The association between leprosy and pregnancy should be routinely investigated, particularly in endemic areas.

Leprosy and pregnancy: detection coefficient and proposal for a new index.

INTRODUCTION: Our study presents a method to generate a novel detection coefficient for the association between leprosy and pregnancy (DCLP). Methods The DCLP was calculated for women from the State of Pará (2007-2009), Brazil. Data were ordered, divided into five equal parts (corresponding to the P20, P40, P60, and P80 percentiles), and classified as low, medium, high, very high, or hyperendemic. RESULTS: Using the new index, we established the DCLP parameters for low (<0.36), medium (0.36-0.69), high (0.70-1.09), very high (1.10-1.50), and hyperendemic (>1.50). CONCLUSIONS: The new DCLP is more appropriate than the overall detection coefficient (DC), which does not take into account the particularities of the interaction between a disease and a specific physiological state.

Analysis of the detection coefficient for the association between leprosy and pregnancy in the integration region of Carajas, State of Para, Brazil

Introduction The association between leprosy and pregnancy is currently poorly understood and has been linked to serious clinical consequences. Methods A retrospective study between 2007 and 2009 was performed in the integration region of Carajás, Brazil on a population of pregnant lepers, with non-lepers of ages 12-49 years serving as the reference population. Results Twenty-nine pregnant lepers were studied during the study period. The detection rates (DRs) for the studied association were 4.7 in 2007, 9.4 in 2008, and 4.3 in 2009. Conclusions The Carajás region presented a medium pattern of endemicity during most of the study period, with a high DR found in 2008. .

Leprosy and pregnancy in the State of Pará: an epidemiological perspective.

INTRODUCTION: A few older publications describe leprosy associated with pregnancy, a situation that has been linked to leprosy exacerbation. This study aimed to describe the detection rate of this association in the State of Pará by county and Integration Region (IR) from 2007 to 2009 via an analysis of socio demographic, epidemiological and operational indices. METHODS: This was a descriptive study using information generated by the SINAN. The Detection Coefficient of the Leprosy and Pregnancy Association (DCLP) epidemiological index was constructed to help interpret the endemicity parameters. The disease was considered hyperendemic when greater than two cases per 10,000 inhabitants were identified. RESULTS: During the study period,149 associations were detected, with 14 hyperendemic counties: seven in 2007, fi ve in 2008 and two in 2009. The Carajás Integrated Region displayed the highest DCLP index in the period. Eldorado dos Carajás had the single highest DCLP index(5.7/10,000 inhabitants, 2008), whereas the DCLP index in Conceição do Araguaia was very high in all three years. However,most counties displayed low or medium DCLP indices. The annual averages were 0.31 DCLP (2007), bass; 0.30 (2008), bass and 0.19 (2009), bass. The average DCLP index was 0.26, which is considered low. Three clusters of medium endemicity were identified by the average DCLP in the study period. CONCLUSIONS: The analyses indicated that the surveillance program is still unsatisfactory in Pará. The interpretation of the endemicity parameters enabled qualitative and quantitative analyses to determine the epidemiological panorama of this association. The identification of high endemicity requires further clarification.

Combination prevention: new hope for stopping the epidemic.

HIV research has identified approaches that can be combined to be more effective in transmission reduction than any 1 modality alone: delayed adolescent sexual debut, mutual monogamy or sexual partner reduction, correct and consistent condom use, pre-exposure prophylaxis with oral antiretroviral drugs or vaginal microbicides, voluntary medical male circumcision, antiretroviral therapy (ART) for prevention (including prevention of mother to child HIV transmission [PMTCT]), treatment of sexually transmitted infections, use of clean needles for all injections, blood screening prior to donation, a future HIV prime/boost vaccine, and the female condom. The extent to which evidence-based modalities can be combined to prevent substantial HIV transmission is largely unknown, but combination approaches that are truly implementable in field conditions are likely to be far more effective than single interventions alone. Analogous to PMTCT, "treatment as prevention" for adult-to-adult transmission reduction includes expanded HIV testing, linkage to care, antiretroviral coverage, retention in care, adherence to therapy, and management of key co-morbidities such as depression and substance use. With successful viral suppression, persons with HIV are far less infectious to others, as we see in the fields of sexually transmitted infection control and mycobacterial disease control (tuberculosis and leprosy). Combination approaches are complex, may involve high program costs, and require substantial global commitments. We present a rationale for such investments and cite an ongoing research agenda that seeks to determine how feasible and cost-effective a combination prevention approach would be in a variety of epidemic contexts, notably that in a sub-Saharan Africa.

Prevalencia de la sífilis en embarazadas de seis ciudades Brasileñas / No disponible

Objetivos: Estimar la prevalencia de sífilis en gestantes de seis ciudades de Brasil y su asociación con variables socioeconómicas, demográficas y de comportamiento. Métodos: Estudio multicéntrico, transversal, que incluyó gestantes atendidas en consultorios prenatales de la atención primaria de salud entre los años 2004 y 2005. Se realizó examen de tamizaje para sífilis usando RPR y examen confirmatorio (ELISA) en la s que resultaron positivas. Se aplicó un cuestionario para colectar informaciones sociodemográficas, clínica-obstétricas, y de la actividad sexual de las voluntarias. Para le análisis estadístico y evaluar los factores de riesgo asociados a la sífilis se realizó análisis bivariado y multivariado por regresión logística múltiple y las pruebas “t” de Studen, Chi2 y test exacto de Fischer. Resultados: Fueron enroladas 3.303 gestantes, cuya edad media fue 23,8 años (± 6,9). La prevalencia de sífilis fue 2,6%. Más de 90% de las gestantes con sífilis presentaban infección latente. El riesgo de tener sífilis fue ocho veces mayor para las gestantes que refirieron haber tenido más de una pareja sexual en el último año. Otros predictores de la infección treponémica fueron: edad mayor de 40 años, nivel de escolaridad baja, tener antecedentes de úlceras genitales, y haber tenido pareja sexual con úlcera genital. Conclusiones: Se observó, en las gestantes brasileras una prevalencia de sífilis elevada. El principal factor de riesgo para esta infección fue tener más de una pareja sexual en los últimos 12 meses (AU)
