RESUMO
Introducción: La hipopotasemia es un trastorno hidroelectrolítico frecuente, asociado a enfermedades sistémicas y multifactoriales, cuya forma aguda puede complicarse y causar la muerte, pero en su presentación crónica puede ser un marcador de nefropatía. Objetivo: Caracterizar el perfil del paciente con hipopotasemia no medicamentosa atendidos de emergencia. Métodos: Se revisaron los registros de pacientes mayores de 18 años con diagnóstico de hipopotasemia, ingresados en el hospital en el período de junio 2018 a diciembre de 2019. Se colectaron datos demográficos, antecedentes médicos y evolución postratamiento. Se comparó con 108 pacientes sin hipopotasemia atendidos en el período de estudio. Resultados: Se encontraron 87 casos con edad media de 38,5 años. El 90,8 por ciento eran hombres menores de 50 años, de oficio agricultor (29,9 por ciento), con historia de exposición a plaguicidas y a altas temperaturas ambientales. La mayoría de ellos no tenía historia de enfermedad cardiometabólicas o renal previa. El 48,3 por ciento de todos los pacientes con hipopotasemia (n = 42) tenía creatinina mayor a 1,2 mg/dL y 63 por ciento tenía hiponatremia. La hipopotasemia fue moderada en 39 por ciento y severa en 12 por ciento, los hombres 4,7 veces más afectados que las mujeres. Respecto al grupo sin hipopotasemia y creatinina anormal, tenían mayor frecuencia de enfermedad crónica (92,5 por ciento versus 8 por ciento). Conclusiones: Se encontró hipopotasemia no medicamentosa en varones agricultores, sin enfermedad crónica, pero con datos de nefropatía temprana e hiponatremia, se sugirió la posibilidad de nefropatía mesoamericana. Debe establecerse una alerta epidemiológica regional y un programa de prevención y control(AU)
Introduction: Hypokalemia is a frequent hydroelectrolytic disorder, associated with systemic and multifactorial diseases, whose acute form can be complicated and cause death, but in its chronic presentation it can be a marker of nephropathy. Objective: To characterize the profile of the patient with non-drug hypokalemia seen in an emergency. Methods: The records of patients older than 18 years diagnosed with hypokalemia, admitted to the hospital from June 2018 to December 2019, were reviewed. Demographic data, medical history, and post-treatment evolution were collected. It was compared with 108 patients without hypokalemia seen in the same period. Results: 87 cases with mean age of 38.5 years were studied. 90.8% were men under 50 years of age, who worked as farmers (29.9percent), with history of exposure to pesticides and high ambient temperatures. Most of them had no history of previous cardiometabolic or renal disease. 48.3percent of all patients with hypokalemia (n = 42) had creatinine higher than 1.2 mg/dL and 63percent had hyponatremia. Hypokalemia was moderate in 39% and severe in 12percent, and it was found that men were affected 4.7 times more than women. Regarding the group without hypokalemia and abnormal creatinine, they had higher frequency of chronic disease (92.5percent versus 8percent). Conclusions: Non-drug hypokalemia was found in male farmers, without chronic disease, but with evidence of early nephropathy and hyponatremia. The possibility of Mesoamerican nephropathy was suggested. A regional epidemiological alert and a prevention and control program should be established(AU)

BACKGROUND: CKD of unknown etiology (CKDu) disproportionately affects young people in Central America who lack traditional CKD risk factors (diabetes and hypertension) and has instead been variably linked to heat stress, occupational and environmental exposures, nephrotoxic medications, and/or genetic susceptibility. This study aimed to estimate the prevalence of CKD and identify risk factors for traditional CKD and CKDu in Nicaragua. METHODS: Surveys and assessment for CKD markers in urine and serum were performed in 15-59 year olds in households of the León municipality of Nicaragua. The survey included questions on demographics, health behaviors, occupation, and medical history. Participants with CKD were subdivided into traditional CKD and suspected CKDu based on history of diabetes, hypertension, or other specified conditions. A multinomial logistic regression model was used to identify factors associated with traditional CKD and suspected CKDu, compared to the non-CKD reference group. RESULTS: In 1795 study participants, CKD prevalence was 8.6%. Prevalence in males was twofold higher than females (12% vs 6%). Of those with CKD, 35% had suspected CKDu. Both traditional CKD and CKDu were associated with male sex and increasing age. Traditional CKD was associated with a family history of CKD, history of urinary tract infections, and lower socioeconomic status, while CKDu was associated with drinking well water and a lower body mass index. CONCLUSIONS: Both traditional CKD and CKDu are significant burdens in this region. Our study supports previous hypotheses of CKDu etiology and emphasizes the importance of CKD screening.
