RESUMO
Candida auris is an emerging pathogen considered to be critical in the World Health Organization fungal organisms list. The study aims to determine the mortality and hospital stays attributed to Candida auris (C. auris) compared to other Candida species in adult patients with candidemia. A retrospective cohort of adults with candidemia was examined from seven centres in Colombia between 2016 and 2021. The primary outcome was 30-day mortality, and the secondary outcome was the length of hospital stay among survivors. Adjustment of the confounding variables was performed using inverse probability weights of exposure propensity score (candidemia by C. auris), survival regression models (Weibull distribution), and a counting model (negative binomial distribution). A value of 244 (47.6%) of the 512 patients with candidemia died within the first 30 days. The crude mortality in C. auris was 38.1% vs. 51.1% in Candida non-auris (CNA). In the Weibull model, mortality in the C. auris group was lower (adjusted HR: aHR- 0.69, 95% CI: 0.53-0.90). Antifungal treatment also decreased mortality, with an aHR of 0.36 (95% CI 0.27-0.47), while the presence of septic shock on patient progression increased it, with an aHR of 1.73 (95% CI 1.41-2.13). Among the patients who survived, no differences in the length of hospital stay were observed between the C. auris and the CNA groups, with an incidence rate ratio of 0.92 (95% CI: 0.68-1.22). Mortality in patients with C. auris bloodstream infections appears lower when adjusted for numerous confounding variables regarding treatment and the presence of septic shock in patient progression. We identified no significant effect of C. auris on the length of hospital stay in surviving patients.
RESUMO
Resumen La lipodistrofia (lipohipertrofia, lipoatrofia) es una complicación dada por la técnica inadecuada de inyección subcutánea de insulina. Se presenta el caso de una paciente de 46 años con diabetes mellitus tipo 2 descontrolada, en tratamiento con insulina glargina 45UI/día, sin control glucométrico y con múltiples ajustes y hospitalizaciones. Al ingreso, el automonitoreo muestra glucometrías basales y posprandiales fuera de metas, glucemia basal de 299 mg/dL y HbA1c de 11%. Al interrogatorio, se evidencian fallas en la técnica de aplicación de insulina, en particular falta de rotación del sitio de aplicación. En el examen físico se encuentra lipohipertrofia dada por panículo adiposo infraumbilical prominente bilateral e induración del tejido celular subcutáneo; en ecografía se visualiza infiltración grasa de rectos anteriores. Se da instrucción a la paciente sobre la correcta técnica de aplicación de insulina con rotación diaria del sitio de aplicación, descanso de zonas con lipohipertrofia y guía para automonitoreo. El automonitoreo en los 10 primeros días mostró mejoría de glucometrías basales hasta 116 mg/dL y valor limítrofe de 75 mg/dL, comparados con promedio de glucometría basal previa de 242 mg/dL con la misma insulina y dosis. Se hizo seguimiento estrecho para definir dosis requerida de insulina y vigilar posible hipoglucemia, con mejoría en la HbA1c de 9.2% y 8.8% a los 4 y 11 meses, respectivamente.
Abstract Lipodystrophy (lipohypertrophy, lipoatrophy) is one of the most common complications of subcutaneous insulin injections. This paper presents the case of a 46-year-old patient with uncontrolled type 2 diabetes mellitus, treated with insulin glargine 45UI/day, no glycemic control and multiple adjustments and hospitalizations. On admission, self-monitoring showed off-target basal and postprandial values, baseline glucose of 299 mg/dL and HbA1c of 11%. Medical history revealed flaws in the technique used for insulin administration, particularly, lack of application site rotation. Physical examination allowed to observe lipohypertrophy caused by excess bilateral infraumbilical adipose panniculus and induration of the subcutaneous cellular tissue. Ultrasound exposed fat infiltration in anterior recti. The patient was instructed on the correct technique for applying insulin with daily rotation of the application site, and allowing the areas affected by lipohypertrophy to rest. A self-monitoring guide was also provided. Self-monitoring within the first 10 days showed improvement in baseline glucose levels up to 116 mg/dL and borderline value of 75 mg/dL, compared to the previous baseline blood glucose level of 242 mg/dL with the same type of insulin and dose. Close follow-up was done to define the required insulin dose and to monitor possible hypoglycemia, obtaining an improvement in HbA1c of 9.2% and 8.8% at 4 and 11 months, respectively.
