ABSTRACT
Objective: To gain better insight into the extent of secondary bacterial and fungal infections in hospitalized patients in India, and to assess how these alter the course of coronavirus disease 2019 (COVID-19) so that control measures can be suggested. Methods: In this retrospective, multicentre study, the data of all patients who tested positive for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) on reverse transcriptase polymerase chain reaction (RT-PCR), admitted to hospital between March 2020 and July 2021, were accessed from the electronic health records of a network of 10 hospitals across five states in North India. Results: Of 19,852 patients testing positive for SARS-CoV-2 on RT-PCR and admitted to the study hospitals during the study period, 1940 (9.8%) patients developed secondary infections (SIs). Patients with SIs were, on average, 8 years older than patients without SIs (median age 62.6 vs 54.3 years; P<0.001). The risk of SIs was significantly (P<0.001) associated with age, severity of disease at admission, diabetes, admission to the intensive care unit (ICU), and ventilator use. The most common site of infection was urine (41.7%), followed by blood (30.8%) and sputum/bronchoalveolar lavage/endotracheal fluid (24.8%); the least common was pus/wound discharge (2.6%). Gram-negative bacilli (GNB) were the most common organisms (63.2%), followed by Gram-positive cocci (GPC) (19.6%) and fungi (17.3%). Most patients with SIs were on multiple antimicrobials. The most commonly used antibiotics against GNB were beta-lactam/beta-lactamase inhibitors (76.9%), carbapenems (57.7%), cephalosporins (53.9%), and antibiotics against carbapenem-resistant Enterobacteriaceae (47.1%). Empirical use of antibiotics against GPC was seen in 58.9% of patients with SIs, and empirical use of antifungals was observed in 56.9% of patients with SIs. The average length of hospital stay for patients with SIs was almost twice as long as that of patients without SIs (median 13 vs 7 days). Overall mortality among patients with SIs (40.3%) was more than eight times higher than that among patients without SIs (4.6%). Only 1.2% of patients with SIs with mild COVID-19 at admission died, compared with 17.5% of those with moderate COVID-19 at admission and 58.5% of those with severe COVID-19 at admission (P<0.001). The mortality rate was highest in patients with bloodstream infections (49.8%), followed by those with hospital-acquired pneumonia (47.9%), urinary tract infections (29.4%), and skin and soft tissue infections (29.4%). The mortality rate in patients with diabetes with SIs was 45.2%, compared with 34.3% in those without diabetes (P<0.001). Conclusions: SIs complicate the course of patients hospitalized with COVID-19. These patients tend to have a much longer hospital stay, a higher requirement for oxygen and ICU care, and a significantly higher mortality rate compared with those without SIs. The groups most vulnerable to SIs are patients with more severe COVID-19, elderly patients and patients with diabetes. Judicious empirical use of combination antimicrobials in these groups of vulnerable patients can save lives. It is desirable to have region- or country-specific guidelines for appropriate use of antibiotics and antifungals to prevent their overuse.
ABSTRACT
Background: Globally, amoebiasis is the second leading cause of death due to parasitic diseases. Amoebic liver abscess (ALA) as an opportunistic infection in recently recovered COVID 19 disease patients has not been reported earlier. Methods: We present here a case series of 13 patients of ALA admitted during the month of May 2021 in BLK hospital, New Delhi, and had recently recovered from COVID 19 disease. Results: Out of 13, eight patients had moderate, and one had severe COVID 19 disease. All these patients had received steroids for the management of COVID 19 disease. The remaining 4 (30%) patients had mild disease. The mean age of our patients was 50 years (37-81 years). Out of 13 patients, nine (70%) were male, 5 were diabetic, 2 were hypertensive, and none were alcoholic. The most common presentation was fever (11/13) followed by upper abdomen pain (10/13). The mean time of symptom (fever or pain abdomen) onset from COVID 19 positivity date was 19 days (range 15-23 days). A complication the in form of localized intraperitoneal rupture was common in these patients and was seen in more than 50% (7/13) of patients. All the patients were managed with IV Metronidazole and abscess aspiration. All the patients were discharged, and the mean hospital stay was 6.6 days. Conclusion: We report here an increase in the incidence of ALA in recently recovered COVID 19 patients and propose that it is most likely due to alteration in the immune state of these patients. It is important for physicians to investigate for liver abscess in patients who present again with fever and/or pain abdomen within 2 weeks of COVID 19 recovery.
