Utility of walk tests in progression of mild COVID-19 infection at a tertiary hospital in North India.

INTRODUCTION: There have been 214 million confirmed cases of COVID-19 worldwide with a total death tally of 4.4 million. The current study aims to determine the predictive value of various scores in assessment of progression of mild COVID-19 infection at a tertiary care hospital in North India. METHODS: The study population consisted of adults (age more than 18 years) with a confirmed diagnosis of COVID-19 by RT-PCR on nasopharyngeal specimens. Patients with only mild illness were enrolled. After the patients were admitted to the isolation ward, the presenting history, comorbidity status, vital signs and laboratory parameters were recorded. The 3 and 6 minute walk test was performed daily from admission till discharge or progression of severity of COVID-19 and it was used to calculate Borg dyspnoea score (BDS) and National Early Warning Score (NEWS2) scores. RESULTS: Our study consisted of 50 patients with 34 (68%) males and the mean (SD) age of the patient population being 28.1 (6.4) years. The most common symptoms were fever, sore throat, and cough. All laboratory parameters were within normal ranges for all the patients. 96% recovered without progression, while only 4% of them progressed to moderate illness. Results of the 3 and 6 minutes walk tests, BDS and NEWS2 scores showed improvement over the course of hospital stay. CONCLUSIONS: Although the walk tests and the scores improved over time, they failed to predict the disease progression.

Safety of SARS-CoV-2 vaccination in patients with inflammatory bowel disease: A systematic review and meta-analysis.

INTRODUCTION: Risk of adverse effects and flare of inflammatory bowel disease (IBD) are frequently cited reasons for COVID-19 vaccine hesitancy. METHODS: Electronic databases were searched to identify studies reporting the use of COVID-19 vaccine in IBD. We selected studies reporting the incidence of various adverse effects (local or systemic) and flares of IBD after COVID-19 vaccination. The pooled incidence rates for various adverse effects, stratified for the dose and the type of vaccine (adenoviral or mRNA) were estimated. RESULTS: Nine studies (16 vaccination cohorts) were included. The pooled incidence rate of overall adverse events was 0.55 (95%CI, 0.45-0.64, I2= 95%). The pooled incidence rate of local adverse events was 0.64 (0.47-0.78, I2= 100%). The pooled incidence rates of fatigue, headache, myalgia, fever and chills were 0.30 (0.21-0.40, I2= 99%), 0.23 (0.17-0.30, I2= 99%), 0.18 (0.13-0.24, I2= 99%), 0.10 (0.06-0.17, I2= 98%) and 0.15 (0.06-0.3, I2= 86%), respectively. The pooled incidence rates of severe adverse events, adverse events requiring hospitalization and flares of IBD following COVID-19 vaccination were 0.02 (0.00-0.12, I2= 97%), 0.00 (0.00-0.01, I2= 27%) and 0.01 (0.01-0.03, I2= 45%), respectively. CONCLUSION: COVID-19 vaccination in patients with IBD appears to be safe with only mild adverse events. Flares of IBD and severe adverse events requiring hospitalization were infrequent.

Effectiveness and Durability of COVID-19 Vaccination in 9447 Patients With IBD: A Systematic Review and Meta-Analysis.

BACKGROUND AND AIMS: The serological responses after severe acute respiratory syndrome coronavirus 2 vaccination may be attenuated in immunocompromised individuals. The study aimed to systematically evaluate the seroconversion rates after complete vaccination for coronavirus disease 2019 (COVID-19) in patients with inflammatory bowel disease (IBD). METHODS: Electronic databases were searched to identify studies reporting response to COVID-19 vaccination in IBD. Pooled seroconversion rates after complete vaccination were calculated. Subgroup analysis for vaccine types was also performed. Pooled seroconversion rates for various drugs or classes were also estimated. The pooled rates of breakthrough infections in vaccinated IBD patients were estimated. The pooled neutralization rates after complete vaccination were also estimated. The studies reporting durability of titers were systematically assessed. RESULTS: A total of 46 studies were included. The pooled seroconversion rate for complete vaccination (31 studies, 9447 patients) was 0.96 (95% confidence interval [CI], 0.94-0.97; I2 = 90%). When compared with healthy control subjects, the pooled relative risk of seroconversion was lower (0.98; 95% CI, 0.98-0.99; I2 = 39%). The pooled seroconversion rates were statistically similar among various drug classes. The pooled positivity of neutralization assays (8 studies, 771 participants) was 0.80 (95% CI, 0.70-0.87; I2 = 82%). The pooled relative risk of breakthrough infections in vaccinated IBD patients was similar to vaccinated control subjects (0.60; 95% CI, 0.25-1.42; I2 = 79%). Most studies suggested that titers fall after 4 weeks of COVID-19 vaccination, and the decay was higher in patients on anti-tumor necrosis factor alone or combination with immunomodulators. An additional dose of COVID-19 vaccine elicited serological response in most nonresponders to complete vaccination. CONCLUSIONS: Complete COVID-19 vaccination is associated with seroconversion in most patients with IBD. The decay in titers over time necessitates consideration of additional doses in these patients.

Clinical predictors of long COVID-19 and phenotypes of mild COVID-19 at a tertiary care centre in India.

A variable proportion of patients develop persistent/prolonged symptoms of Coronavirus Disease 2019 (COVID-19) infection (long COVID). We aimed to study the clinical predictors of persistent symptoms in patients with mild COVID-19 at 30 days post discharge (long COVID-19). We also tried to identify symptom clusters among mild COVID-19 patients. Fifty-seven patients admitted at a tertiary care centre after a positive RT-PCR report over a period of 2 months, were enrolled in the study. Details of presentation, history of illness, laboratory investigations and disease outcomes were recorded from documented medical records and discharge slip. The patients were contacted (telephonically) at 30 days after discharge and enquired regarding persistent symptoms, if any. Follow up data at 30 days post-discharge was available for 53 patients. Among them, the most common persistent symptom was fatigue (22.6%), followed by cough (9.4%) and myalgias (7.5%). There was a significant association of persistent symptoms with diarrhoea at presentation [OR 14.26 (95% CI 2.30-142.47; p = 0.009] and gap between symptom onset and admission [OR 1.40 (95% CI 1.08-1.93; p = 0.020] on multivariate logistic regression analysis. On cluster analysis, three phenotypes of mild COVID-19 were identified, which may have implications on monitoring and management. There appears to be a positive association of diarrhoea as a presenting manifestation and gap between symptom onset and admission with the persistence of symptoms classified as long COVID-19, even in mild illness. We also identified multiple phenotypes of mild COVID-19 illness, which warrant further exploration.

Clinical presentation of COVID-19 in patients with inflammatory bowel disease: a systematic review and meta-analysis.

BACKGROUND/AIMS: Coronavirus disease 2019 (COVID-19) is recognized to have variable clinical manifestations. The clinical presentation of patients with inflammatory bowel disease (IBD) having COVID-19 is unclear. METHODS: We identified articles reporting about the clinical presentation of COVID-19 in those with underlying IBD from PubMed and Embase. The studies, irrespective of design or language, were included. The overall pooled frequency of various symptoms was estimated. Joanna Briggs Institute Critical appraisal checklist was used to assess the quality of studies. RESULTS: Eleven studies, including 1,325 patients, were included in the pooled analysis. The pooled estimates for clinical presentation were; fever: 67.53% (95% confidence interval [CI], 45.38-83.88), cough: 59.58% (95% CI, 45.01-72.63), diarrhea: 27.26% (95% CI, 19.51-36.69), running nose: 27% (95% CI, 15.26-43.19) and dyspnea: 25.29% (95% CI, 18.52-33.52). The pooled prevalence rates for abdominal pain, nausea and vomiting were 13.08% (95% CI, 9.24-18.19), 10.08% (95% CI, 5.84-16.85) and 8.80% (95% CI, 4.43-16.70) per 100 population, respectively. CONCLUSIONS: The clinical presentation of COVID-19 in IBD patients is similar to the general population.

Mild COVID-19 infection-predicting symptomatic phase and outcome: A study from AIIMS, New Delhi.

CONTEXT: Comprehensive management of mild COVID infection calls for better understanding of symptomatology in these group of patients as well as early identification and close monitoring of patients at risk, data on which is limited. AIM: To study association between inflammatory markers and clinical presentation with progression of disease and the duration of resolution of symptoms. SETTINGS AND DESIGN: This is a retrospective study that has been conducted at a designated COVID -19 medical ward at AIIMS, New Delhi. METHODS AND MATERIAL: Fifty healthcare workers and their dependents who were admitted with asymptomatic and mild COVID-19 infection were included. Their records were retrospectively reviewed, entered into a predesigned proforma and analyzed. RESULTS: A total of 50 participants were included in the study of which 70% were healthcare workers. The patients were admitted with mild COVID illness out of which 22 (44%) were males. Most common symptom at presentation was fever (72%). Among patients who had mild disease versus those who progressed to moderate illness (n = 3), the patients with moderate illness were older [mean (SD): 57.33 (10.21) vs. 36.13 (14.05); P = 0.014] and had a longer duration of hospital stay [17 (1.41) days vs. 11.20 (3.86) days; P = 0.04]. Inflammatory markers, C-Reactive Protein (CRP) [2.46 vs. 0.20 (P = 0.024)], and Ferritin [306.15 vs. 72.53 (P = 0.023)] were higher in patients with moderate illness. There is also a significant correlation between the number of days taken for symptoms to resolve with Serum Ferritin (P = 0.007), CRP (P = 0.0256), and neutrophil lymphocyte ratio (NLR) (P = 0.044). CONCLUSIONS: Acute phase reactants/Inflammatory markers serve as good indicators of time taken to resolution of symptoms in acute COVID infection. NLR is a simple and inexpensive method to provide insight into symptomatic phase. These may be utility tools for primary care physician in the management in periphery and timely decision.

Risk factors and outcome among COVID-19 exposed and quarantined healthcare workers: A study on the status of existing practices of standard precautions.

CONTEXT: Health care workers (HCWs) are at high risk of COVID-19 infection but data on the risk factors for exposure and infection rate among Indian HCWs are limited. AIMS: Our study aims to identify the risk factors and behavior of HCWs which make them high risk for COVID-19 infection and the infection rate among them. SETTINGS AND DESIGN: This is a retrospective study conducted at All India Institute of Medical Sciences, New Delhi. METHODS AND MATERIAL: Fifty HCWs quarantined at our institute in April and May 2020 following exposure to confirmed or suspected COVID-19 cases, or due to development of Influenza-Like Illness (ILI) were included. Data was collected from medical records in a predesigned proforma and analyzed. RESULTS: Thirty-eight (76%) of the 50 quarantined HCWs had high-risk exposure and there was a significant breach in personal protective measures. N-95 masks were worn by 59.6%, gloves by 61.7%, and goggles or face shields by 2%. Exposures were more common in non-COVID areas of the hospital. Hydroxychloroquine pre-exposure prophylaxis was taken by 7 (14%). 3 (6%) were confirmed to be COVID-19 positive during the quarantine period. CONCLUSIONS: Our study has shown leniency among HCWs in adhering to infection control and personal protective measures resulting in an increased quarantine and infection rate and loss of manpower. The safety of our HCWs must be given paramount importance during this pandemic and should be ensured by educating them about infection control, and persistently reinforcing and strictly adhering to standard precautions.
