RESUMO
BACKGROUND: Despite the low rate of bacterial coinfection, antibiotics are very commonly prescribed in hospitalized patients with COVID-19. RESEARCH QUESTION: Does the use of a procalcitonin (PCT)-guided antibiotic protocol safely reduce the use of antibiotics in patients with a COVID-19 infection? STUDY DESIGN AND METHODS: In this multicenter cohort, three groups of patients with COVID-19 were compared in terms of antibiotic consumption, namely one group treated based on a PCT-algorithm in one hospital (n = 216) and two control groups, consisting of patients from the same hospital (n = 57) and of patients from three similar hospitals (n = 486) without PCT measurements during the same period. The primary end point was antibiotic prescription in the first week of admission. RESULTS: Antibiotic prescription during the first 7 days was 26.8% in the PCT group, 43.9% in the non-PCT group in the same hospital, and 44.7% in the non-PCT group in other hospitals. Patients in the PCT group had lower odds of receiving antibiotics in the first 7 days of admission (OR, 0.33; 95% CI, 0.16-0.66 compared with the same hospital; OR, 0.42; 95% CI, 0.28-0.62 compared with the other hospitals). The proportion of patients receiving antibiotic prescription during the total admission was 35.2%, 43.9%, and 54.5%, respectively. The PCT group had lower odds of receiving antibiotics during the total admission only when compared with the other hospitals (OR, 0.23; 95% CI, 0.08-0.63). There were no significant differences in other secondary end points, except for readmission in the PCT group vs the other hospitals group. INTERPRETATION: PCT-guided antibiotic prescription reduces antibiotic prescription rates in hospitalized patients with COVID-19, without major safety concerns.

BACKGROUND: Proton pump inhibitors (PPIs) are among the most widely used drugs around the globe. A growing body of literature, however, has reported numerous side effects, such as hypomagnesemia. Symptoms associated with hypomagnesaemia range from nausea, tetany and cardiac arrhythmias. Treatment of PPI-induced hypomagnesaemia involves discontinuation of the PPI and magnesium supplementation if needed. CASE DESCRIPTION: A 72-year-old female was admitted to the ICU with omeprazole-induced severe hypomagnesaemia twice during a one-year timespan, clinically manifested by tetany and respiratory failure due to acute decompensated heart failure following new onset atrial fibrillation. After discontinuation of the PPI and intravenous magnesium supplementation she recovered fully. CONCLUSION: Hypomagnesaemia is a potentially serious adverse effect of PPIs. Serum magnesium levels should be monitored in chronic PPI-users with any neuromuscular, cardiovascular or non-specific symptoms, especially in the presence of known risk factors (alcohol use, malnutrition, malabsorption, hypertension and concomitant use of diuretics).

OBJECTIVE: To investigate whether advanced age may be a reason to refrain from treatment in patients with an acute abdominal aortic aneurysm (AAAA). METHODS: This was a retrospective cohort study that took place in a tertiary care university hospital with a 45-bed intensive care unit. Two hundred seventy-one patients with manifest AAAA, admitted and treated between January 2000 and February 2008, were included. Six patients died during operation and were included in the final analysis to ensure an intention-to-treat protocol, resulting in 234 men and 37 women with a mean age of 72 ± 7.8 years (range, 54-88 years). Forty-six patients (17%) were 80 years or older. Interventions involved open or endovascular AAAA repair. RESULTS: Mean follow-up was 33 ± 30.4 months (including early deaths). Mean hospital length of stay was 16.9 ± 20 days for patients younger than 80 and 13 ± 16.7 days for patients older than 80 years of age. Kaplan-Meier survival analysis revealed a significantly better survival for the younger patients (P < .05). Stratification based on urgency or type of treatment did not change the difference. Two-year actuarial survival was 70% for patients younger than 80 and 52% for those older than 80. At 5-year follow-up, these figures were 62% and 29%, respectively. Mean survival in patients older than 80 was 39.8 ± 6.8 months versus 64.5 ± 3.0 months in those younger than 80. CONCLUSIONS: For octogenarians, our liberal strategy of treating patients with AAAA was associated with satisfactory short- and long-term outcome, with no difference with regard to disease- or procedure-related morbidity between the younger and older group. Assuming an integrated system for managing AAAA is in place, advanced age is not a reason to deny patients surgery.
