RESUMO

Rickettsioses and leptospirosis are infectious diseases that are often underdiagnosed due to a lack of knowledge about their epidemiology, pathophysiology, diagnosis, management, among others. Objetive: to characterize the seroprevalence and seroincidence of both Rickettsia and Leptospira agents and determine the risk factors for these outcomes in rural areas of Urabá, Antioquia. Methods: a secondary data analysis using information on Rickettsia and Leptospira exposure from a prior prospective study that explored sociocultural and ecological aspects of Rickettsia infection in rural Urabá, Colombia. A multinomial mixed logistic regression model was employed to analyze factors linked to seroprevalent cases of Rickettsia, Leptospira and both, along with descriptive analyses of seroincident cases. Results: the concomitant seroprevalence against Rickettsiaand Leptospira was 9.38% [95%CI 6.08%-13.37%] (56/597). The factors associated with this seroprevalence were age (ORa= 1.02 [95%CI 1.007-1.03]), male gender (ORa= 3.06 [95%CI 1.75-5.37]), fever history (ORa= 1.71 [95%CI 1.06-2.77]) the presence of breeding pigs (ORa= 2.29 [95%CI 1.36-3.88]), peridomicile yucca crops(ORa= 2.5 [95%CI 1.1-5.62]), and deforestation practices(ORa= 1.74 [95%CI 1.06-2.87]). The concomitant seroincidence against Rickettsia and Leptospira was 1.09% (3/274) [95%CI 0.29%-4.05%], three cases were female, with a median age of 31.83 years-old (IQR 8.69-56.99). At the household level, all the seroincident cases had households built partially or totally with soil floors, wooden walls, and zinc roofs. Two seroincident cases described the presence of equines, canines, and domestic chickens in intra or peri-domicile. Finally, two cases were exposed to synanthropic rodents, and one case to tick infestation. Conclusion: there is evidence of seroprevalent and seroincident cases of seropositivity against both Rickettsia and Leptospira in rural areas of Urabá, Colombia. These findings can help improve public health surveillance systems in preventing, detecting, and attending to the different clinical cases caused by these pathogens.

RESUMO

Resumen Introducción: el lupus eritematoso sistémico (LES) presenta diferentes manifestaciones clínicas, un de estas es la nefropatia lúpica (NL), que se asocia con progresión a enfermedad renal crónica (ERC) avanzada y mortalidad. Objetivo: determinación de las características clínicas y epidemiológicas de la NL en Santander. Métodos: estudio observacional descriptivo tipo serie de casos en pacientes con NL evaluados por primera vez, entre enero de 2017 a enero 2018, en consulta de nefroprevención. Según criterios de inclusión y exclusión se definieron variables cualitativas y cuantitativas. Se revisaron historias clínicas y el análisis de datos se realizó por medio de SPSS®. Resultados: se estudiaron 14 pacientes (85 % mujeres), la edad promedio de diagnóstico de NL fue de 36 años, con ERC 1 y 2 (72 %) y con proteinuria A3 (85 %). Se obtuvo biopsia renal en 64 %, con resultado concluyente en el 50 %, la clase histopatológica IV de NL fue la más común. La terapia de mantenimiento más frecuente fue corticoide en monoterapia (36 %), seguido de la combinación de corticoide y micofenolato (29 %). Conclusión: la NL predomina en mujeres jóvenes, en estadios tempranos de ERC con altos grados de proteinuria, por lo que se debe realizar una evaluación minuciosa en búsqueda de NL a todos los pacientes con LES, mediante programas de detección y seguimiento nefrológico temprano. El grado histopatológico IV fue el más frecuente, similar a lo reportado en Latinoamérica. Existen dificultades administrativas y técnicas en la toma de biopsias renales, se debe hacer énfasis en la necesidad de su realización, por su primordial importancia para definir el tratamiento.


Abstract Introduction: Systemic Lupus Erythematosus (SLE) has different clinical manifestations, being very relevant lupus nephropathy (NL) because is associated with progression to advanced chronic kidney disease (CKD) and mortality. Objective: Determination of the clinical and epidemiological characteristics of the NL in Santander. Methods: A descriptive observational study of a series of cases in patients with NL diagnosis, evaluated between January 2017 and 2018 for the first time in a nephroprotection consultation. Qualitative and quantitative variables are defined according to the inclusion and exclusion criteria. Electronic medical records were reviewed, and data analysis was performed through SPSS®. Results: 14 patients (85% women) were studied. The average age of diagnosis of NL was 36 years, mostly with stages of CKD 1 and 2 (72%) with proteinuria A3 (85%).Biopsy renal was performed in the 64%, a conclusive result in the 50%, being the histopathological grade IV of NL the most common. The most frequent maintenance therapy was corticosteroid alone (35.7%), followed by the combination of corticosteroid and mycophenolate (28.5%). Conclusion: NL predominates in young women, and presenting in early stages of CKD, with high degrees of proteinuria, so a thorough evaluation should be performed in search of NL in all patients with SLE through early nephrological screening and monitoring programs. The histopathological grade IV found is like that reported in Latin America. There are administrative and technical difficulties in the performance of renal biopsies, emphasis should be placed on the realization of this procedure because it takes a primary role in defining the treatment.
