Título

Assessment of the clinical profile of patients with obesity and asymptomatic COVID-19 undergoing bariatric surgery in Brazil

Introdução

Obesity has been pointed as the main risk factor for the aggravation of COVID-19 cases, with lots of studies showing higher necessity of mechanical ventilation, longer hospital stay and higher mortality rates in this population. However, successive cases of patients with grade II obesity presenting positive RT-PCR for Sars-CoV-2 without symptoms were observed in the preoperative period of bariatric surgery.

Objetivo

Outline the clinical and laboratorial profile of patients with obesity undergoing bariatric surgery who presented positive RT-PCR for Sars-CoV-2 in the preoperative period without symptoms presentation.

Método

Case series of 17 patients undergoing bariatric surgery who presented RT-PCR for Sars-CoV-2 in the preoperative period, with no reported symptoms. Data collected included demographic characteristics, length of hospital stay, waiting time for surgery, inflammatory response laboratory markers and micronutrients serum levels.

Resultados

In total, 219 patients underwent bariatric surgery in our institution during the study period. The incidence of asymptomatic cases was 7.7%. The sample comprised 88.2% of women, with mean age of 39.3 years and mean preoperative BMI of 37.7 Kg/m2. Thirty five percent of the sample had previous diagnosis of diabetes and 29.4% had hypertension. The mean time elapsed between a positive RT-PCR and the operation was 17 ± 7.5 days and the mean length of postoperative hospital stay was 1.9 ± 0.43 day. Mean lymphocytes count was 2,409.7/mm3 and the mean platelet-to-lymphocyte ratio was 126.3. Mean C-reactive protein value was 5.8mg/dL, while ferritin marked 107.4 µg/L. Dengue virus (DENV) IgG was identified in all patients who tested for it. Mean levels of vitamin D and zinc were 25.6 ng/mL and 79.9 µg/dL, respectively. There were no postoperative complications reported.

Conclusão

None of the included patients presented any of the laboratory markers related to disease severity. Moreover, it is important to notice that all patients who tested for DENV, had the specific IgG detected in their serum.
