COVID-19 associated Mucormycosis (CAM): Implications for perioperative physicians - A narrative review.

Mucormycosis once considered a rare disease with an incidence of 0.005 to 1.7 per million, has become one of the greatest menaces during the coronavirus disease (COVID-19) pandemic. India alone has contributed to nearly 70% of the global caseload of COVID-associated mucormycosis (CAM) and it had even been declared as a notifiable disease. Second wave of COVID-19 pandemic saw a steep rise in the incidence of mucormycosis and these patients have been presenting to anesthesiologists for various surgical procedures due to its primary or secondary sequelae. Rhino-orbito-cerebral mucormycosis (ROCM) is the commonest manifestation and is caused by Rhizopus arrhizus. Injudicious use of corticosteroids in vulnerable patients could have been a major contributing factor to the sudden rise in ROCM during the pandemic. Concerns related to anesthetic management include COVID-19 infection and post COVID sequalae, common presence of uncontrolled diabetes mellitus, possibility of difficult mask-ventilation and/or intubation, various drug therapy-associated adverse effects, and interaction of these drugs with anesthetic agents. Thorough preoperative optimization, multidisciplinary involvement, perioperative care, and vigilance go a long way in improving overall outcomes in these patients.

The Effectiveness of SARS-CoV-2 Vaccination in Preventing Severe Illness and Death - Real-world Data from a Cohort of Patients Hospitalized with COVID-19.

Background: While long-term studies on the correlates of protection, vaccine effectiveness, and enhanced surveillance are awaited for SARS-CoV-2 vaccine, studies on breakthrough infections help understand the nature and course of this illness among vaccinated individuals and guide in public health preparedness. This study aims to compare the differences in the hospitalization outcomes SARS-CoV-2 infection of fully vaccinated individuals with with those of unvaccinated and partially vaccinated individuals. Materials and Methods: Single institution observational cohort study. This study compared the differences in clinical, biochemical parameters and the hospitalization outcomes of 53 fully vaccinated individuals with those of unvaccinated (1464) and partially vaccinated (231) individuals, among a cohort of 2,080 individuals hospitalized with SARS-CoV-2 infection. Descriptive statistics and propensity-score weighted multivariate logistic regression analysis adjusting for clinical and laboratory parameters were used to compare the differences and to identify factors associated with outcomes. Results: Completing the course of vaccination protected individuals from developing severe COVID-19 as evidenced by lower proportions of those with hypoxia, abnormal levels of inflammatory markers, requiring ventilatory support, and death compared to unvaccinated and partially vaccinated individuals. There were no differences in these outcomes among patients who received either vaccine type approved in India. Conclusions: Efforts should be made to improve the vaccination rates as a timely measure to prepare for the upcoming waves of this highly transmissible pandemic. Vaccination rates of the communities may also guide in the planning of the health needs and appropriate use of medical resources.

A Cross-Sectional Study to Ascertain the Effect of COVID-19 Pandemic on Regional Anaesthesia Practices Amongst Anaesthesiologists of India

Background and aims Regional anaesthesia has been advocated as a preferred modality during the coronavirus disease 2019 (COVID‑19) pandemic, but pursuing regional anaesthesia during COVID-19 is challenging. Our cross-sectional survey aimed to analyze the challenges in conducting regional anaesthesia and the alterations in practices imposed by the COVID‑19 pandemic across the nation. Material and methods The questionnaire was validated by seven experts. Following ethical approval and trial registration, this Google Forms-based survey was circulated to anaesthesiologists across the country via emails over 3 months (April 2021 to June 2021). Weekly reminders were sent to the non-responders till the desired sample size was attained, after which the survey was closed and responses were analyzed. Results Five hundred and thirty-two of 1100 anaesthesiologists completed the survey (48.3% response rate). Among the 532 respondents, 65.8% reported an increase in the use of regional anaesthesia due to the pandemic, with 77.4% reporting a change in practice. Almost 90% of the respondents used a dedicated operation theatre for all infected patients. Most respondents (75%) used disposable plastic drapes (75%) and full personal protective equipment (PPE) for COVID-19-positive patients during the procedure. However, using PPE resulted in poor vision due to fogging and multiple attempts and increased performance duration. Most respondents (74.4%) used gloves to maintain ultrasound probe sterility, while many other respondents (65.7%) used a sterile camera cover for the same. Many respondents ordered inflammatory markers during preoperative evaluation. Conclusion The present survey revealed that there was increased utilization of regional anaesthesia with increased utilization of PPE, sterility routines, and ordering of investigations. The use of PPE led to many challenges while performing regional anaesthesia. However, many deviations were identified from the accepted recommendations, and one needs to be aware of proper practices to achieve optimal patient outcomes and provider safety.

Nationwide impact of COVID-19 pandemic on postgraduate medical teaching, research, and mental stress: A cross-sectional online questionnaire-based survey.

Background and Aims: Coronavirus disease-2019 (COVID-19) pandemic has affected postgraduate medical education, training, and ongoing research work across specialties. Our survey aimed to analyze the effect of COVID-19 on challenges in pursuing research and academics and ascertain the stressors on residents across medical specialties. Material and Methods: The questionnaire was validated by 10 experts and following ethical approval, this google form-based survey was circulated to postgraduates across specialties across the country through social media platforms over 1 month (22 August 2020 to 21 September 2020). On clicking the link, the participants received brief information regarding the survey followed by the questionnaire. Weekly reminders were sent to the nonresponders till the desired sample size was attained, after which the survey was closed, and responses were analyzed. Results: Four hundred and nineteen of 900 residents completed the survey (46.6% response rate). Majority (88.8%) admitted that the inability to conduct the thesis and break in academics caused a significant amount of mental stress upon them. Though classes had resumed through online platforms for most residents (75.4%), the residents reported that lack of bedside learning (65.4%), inadequate progress tests (26.4%), and delay in thesis topic allotment (84.6% among those not allotted thesis) correlated with increased stress. Fear of extension of the course (53%; P = 0.019) and getting infected with COVID-19 (46.6%; P = 0.019) were most cited reasons for significant stress in most of the residents. Many residents (26%) were unable to sleep properly and 22.1% were unable to concentrate on academics. Majority believed that extension of the submission deadline, reduction in sample size, and change in topic would help to complete thesis. Conclusion: The present survey revealed that there is a major impediment to research and academics of medical postgraduates during COVID-19 pandemic which has markedly increased their stress levels.

Airway management, procedural data, and in-hospital mortality records of patients undergoing surgery for mucormycosis associated with coronavirus disease (COVID-19).

PURPOSE: Although unexpected airway difficulties are reported in patients with mucormycosis, the literature on airway management in patients with mucormycosis associated with Coronavirus disease is sparse. METHODS: In this retrospective case record review of 57 patients who underwent surgery for mucormycosis associated with coronavirus disease, we aimed to evaluate the demographics, airway management, procedural data, and in-hospital mortality records. RESULTS: Forty-one (71.9%) patients had a diagnosis of sino-nasal mucormycosis, fourteen (24.6%) patients had a diagnosis of rhino-orbital mucormycosis, and 2 (3.5%) patients had a diagnosis of palatal mucormycosis. A total of 44 (77.2%) patients had co-morbidities. The most common co-morbidities were diabetes mellitus in 42 (73.6%) patients, followed by hypertension in 21 (36.8%) patients, and acute kidney injury in 14 (28.1%) patients. We used the intubation difficulty scale score to assess intubating conditions. Intubation was easy to slightly difficult in 53 (92.9%) patients. In our study, mortality occurred in 7 (12.3%) patients. The median (range) mortality time was 60 (27-74) days. The median (range) time to hospital discharge was 53.5 (10-85) days. The median [interquartile range] age of discharged versus expired patients was 47.5 [41,57.5] versus 64 [47,70] years (P = 0.04), and median (interquartile range) D-dimer levels in discharged versus expired patients was 364 [213, 638] versus 2448 [408,3301] ng/mL (P = 0.03). CONCLUSION: In patients undergoing surgery for mucormycosis associated with the coronavirus disease, airway management was easy to slightly difficult in most patients. Perioperative complications can be minimized by taking timely and precautionary measures.

Silent Hypoxia in Coronavirus disease-2019: Is it more dangerous? -A retrospective cohort study.

Background: Hypoxia in patients with COVID-19 is one of the strongest predictors of mortality. Silent hypoxia is characterised by the presence of hypoxia without dyspnoea. Silent hypoxia has been shown to affect the outcome in previous studies. Methods: This was a retrospective study of a cohort of patients with SARS-CoV-2 infection who were hypoxic at presentation. Clinical, laboratory and treatment parameters in patients with silent hypoxia and dyspnoeic hypoxia were compared. Multivariate logistic regression models were fitted to identify the factors predicting mortality. Results: Among 2080 patients with COVID-19 admitted to our hospital, 811 patients were hypoxic with SpO2 <94% at the time of presentation. Among them, 174 (21.45%) did not have dyspnoea since the onset of COVID-19 symptoms. Further, 5.2% of patients were completely asymptomatic for COVID-19 and were found to be hypoxic only on pulse oximetry. The case fatality rate in patients with silent hypoxia was 45.4% as compared to 40.03% in dyspnoeic hypoxic patients (P = 0.202). The odds ratio of death was 1.1 (95% CI: 0.41-2.97) in the patients with silent hypoxia after adjusting for baseline characteristics, laboratory parameters, treatment and in-hospital complications, which did not reach statistical significance (P = 0.851). Conclusion: Silent hypoxia may be the only presenting feature of COVID-19. As the case fatality rate is comparable between silent and dyspnoeic hypoxia, it should be recognised early and treated as aggressively. Because home isolation is recommended in patients with COVID-19, it is essential to use pulse oximetry in the home setting to identify these patients.

Effect of Nation-wide Lockdown on Palliative Care Services in a Tertiary Care Centre in India: A Retrospective Observational Study.

BACKGROUND: The ongoing coronavirus disease 2019 (COVID-19) pandemic has affected all the aspects of life of mankind, posing unique challenges for health-care services. In order to contain the spread of the virus, a countrywide mass lockdown has been imposed in India. Although the lockdown has modified the epidemic trajectory, it has affected the lives of many non-COVID patients. Patients in need of care could not approach hospitals. METHODS: This retrospective observational study was conducted in the Department of Onco-Anaesthesia and Palliative Medicine at a tertiary care center in India. The yearly data of patient flow for the year 2019 was compared with that during the lockdown. RESULTS: The single-day average of out-patients, in-patients, and other department consultation requests requiring palliative care decreased drastically during the lockdown in comparison to the previous year. The single-day average of teleconsultations increased more than double during the lockdown. CONCLUSION: Although lockdown decreases the spread of the epidemic, it increases the suffering of other patients who require medical care. Various steps have to be adopted in the regular working pattern of hospitals to cater to the needs of the patients requiring care, without increasing the risk of contracting COVID-19.

Concerns of Health Care Professionals Managing non-COVID Patients during The COVID-19 Pandemic: A Descriptive Cross- Sectional Study.

CONTEXT: The coronavirus pandemic has put an unprecedented burden on the health-care workers who are the cornerstone of the work system, preparing to mitigate its effects. Due to the lack of protective equipments, guidelines for managing patients, or proper training and education regarding the same, health care professionals (HCPs) working in non-COVID areas may face even greater problems than those working in COVID areas of a hospital. Our aim was to find out the concerns of HCPs working in non-COVID areas. SUBJECTS AND METHODS: After obtaining institutional ethics approval, a descriptive cross-sectional study was planned. An online Google-based questionnaire was rolled out to all doctors through various social media platforms who were dealing with COVID-negative patients. RESULTS: We received a total of 110 responses. 84.5% of participants were concerned about the risk of infection to self and family, 67.3% were concerned by the disruption of their daily activities. 56.4% of HCPs were disturbed by the lack of any concrete protocol for patient management. Less staff availability, delay in discharging duties toward their patients, and increased workload were other concerns. More than half of the doctors received N-95 masks whenever required and were trained in donning and doffing of Personal protective equipment. Sixty-eight percemt of our respondents labeled their current quality of life as stressful. CONCLUSION: It is the need of the hour to develop a comprehensive strategy focussing on the above challenges that HCPs working in non-COVID areas are facing. This will go a long way in not only providing holistic care to the patients but also in controlling this pandemic.

Smartphone-Based Telemedicine Service at Palliative Care Unit during Nationwide Lockdown: Our Initial Experience at a Tertiary Care Cancer Hospital.

BACKGROUND AND AIMS: With the COVID-19 pandemic, lockdown, and fear from contagion, the advantages of telemedicine are clearly outweighing the setbacks by minimizing the need for individuals to visit health-care facilities. Our study aims to assess how palliative medicine physicians could follow up on cancer patients and barriers they faced, discuss their results, and evaluate their treatment response with the help of telemedicine. MATERIALS AND METHODS: We conducted a prospective analysis of the smartphone-based telemedicine service at our palliative care (PC) unit from March 25, 2020, to May 13, 2020. We recorded the patient's reason for call, main barriers to a hospital visit, and the assistance given to them by the physician on call. Each caller was asked to measure his/her satisfaction with the service on a 4-point scale. RESULTS: Out of 314 patients, 143 (45.54%) belonged to Delhi and 171 (54.46%) belonged to other states. 157 patients sought help for symptom management; 86 patients needed to restock their opioid medications. Seventy-one patients required information regarding their oncological treatments requiring consultation from other departments. Titration of oral opioids and medication prescription (n = 129), contact details of other PC units at their native state for opioid procurement (n = 55), and attachment to our community-based PC service (n = 22) were main modes of management. Fifty-six patients were very satisfied and 152 patients were satisfied with the service. CONCLUSION: Telemedicine is the future of health-care delivery systems. In PC, we deal with immunocompromised debilitated cancer patients and telemedicine is immensely helpful for us to provide holistic integrated care to these patients who are unable to visit hospitals regularly.

Opioid Dispensing Patterns from a Tertiary Care Cancer Hospital during the Nationwide Lockdown in COVID-19 Pandemic.

INTRODUCTION: During the current COVID-19 crisis, striking a balance between adequate pain relief in advanced malignancy patients and avoiding hospitals due to fear of contracting the infection has been the biggest challenge for patients as well as palliative care physicians. This study explored the trends in opioid dispensing for cancer pain before and during the lockdown. METHODS: The trends were calculated based on an analysis of quantity of all opioids dispensed. March 24, 2020, was considered as a cutoff for analyzing before and during lockdown period dispensing trends. No information regarding individual patients was retrieved in the current study. RESULTS: There was a decrease in total morphine, tramadol, and fentanyl patch dispensing parallel to decrease in total number of patients visiting the outpatient department. However, there was a statistically significant increase in per capita opioid dispensing during the lockdown period. There was also an increase in the proportion of cancer pain patients that were dispensed morphine during the lockdown. CONCLUSION: Despite the lockdown, the palliative care team at Institute Rotary Cancer Hospital has continued to provide adequate pain relief to patients that could manage to reach the center. Policy-makers need to be cognizant of the pain relief needs of cancer patients in times when accessing hospitals is becoming increasingly difficult. Cancer-related pain and mortality could well be the next pandemic once the current COVID-19 begins to reduce.

Six-minute walk test and its predictability in outcome of COVID-19 patients.

BACKGROUND: The world is worsely hit by the COVID-19 pandemic resulting in increased morbidity and mortality. Increased mortality has been observed in older adults with multiple comorbidities. Six-minute walk distance (6MWD) at admission can help us to guide the requirement of oxygen during hospital stay that can be used to determine which patient can be managed at home. MATERIALS AND METHODS: This study was a prospective observational study conducted on COVID-19 patients admitted at AIIMS, New Delhi, from October to December 2020. Patients aged more than 60 years were included in the study and underwent 6-min walk tests. Polypharmacy and multimorbidity were also assessed along with dyspnea which was measured on BORG scale. P < 0.05 was considered statistically significant. Statistical software STATA (version 14.2) was used for all the analyses. RESULTS: The mean age of the study population was 68.76 (7.4). Oxygen saturation prior to the 6-MWT was normal and has significantly higher than the post test (P ≤ 0.001). 6MWD was significantly correlated with pre values of oxygen saturation. 6MWD was observed more in patients who did not require oxygen during hospital stay. Self-reported dyspnea, pulse rate, oxygen saturation, and systolic blood pressure were significantly associated with the patients who had an oxygen requirement during the hospital stay. CONCLUSION: Self-reported dyspnea after 6MWT was found to be associated with oxygen requirement during hospital stay. Patients who have covered more distance in 6-min walk test have less oxygen requirement during hospital stay hence can be managed at home. This will reduce the health-care burden and will help to tackle the outburst during the ongoing pandemic.

Clinical features, demography, and predictors of outcomes of SARS-CoV-2 infection at a tertiary care hospital in India: A cohort study.

BACKGROUND: The "second wave" of the COVID-19 pandemic hit India from early April 2021 to June 2021. We describe the clinical features, treatment trends, and baseline laboratory parameters of a cohort of patients with SARS-CoV-2 infection and their association with the outcome. METHODS: This was a retrospective cohort study. Multivariate logistic regression models were fitted to identify clinical and biochemical predictors of developing hypoxia, deterioration during the hospital stay, and death. RESULTS: A total of 2080 patients were included. The case fatality rate was 19.5%. Among the survivors, the median duration of hospital stay was 8 (5-11) days. Out of 853 (42.3%%) of patients who had COVID-19 acute respiratory distress syndrome at presentation, 340 (39.9%) died. Patients aged >45 years had higher odds of death as compared to the 18-44 years age group. Vaccination reduced the odds of death by 40% (odds ratio [OR] [95% confidence interval [CI]]: 0.6 [0.4-0.9], P = 0.032). Patients with hyper inflammation at baseline as suggested by leukocytosis (OR [95% CI]: 2.1 [1.5-3.1], P < 0.001), raised d-dimer >500 mg/dL (OR [95% CI]: 3.2 [2.2-4.7], P < 0.001), and raised C-reactive peptide >0.5 mg/L (OR [95% CI]: 3.7 [2.2-13], P = 0.037) had higher odds of death. Patients who were admitted in the 2nd week had lower odds and those admitted in the 3rd week had higher odds of death. CONCLUSION: This study shows that vaccination status and early admission during the inflammatory phase can change the course of illness of these patients. Improving vaccination rates and early admission of patients with moderate and severe COVID-19 can improve the outcomes.

Impact of COVID-19 Pandemic on Cancer Surgical Services-AIIMS, New Delhi Experience.

COVID pandemic has impacted cancer care delivery and cancer surgical services globally. There is an urgent need to study the extent of the impact of COVID on cancer surgery and individual institutional response and strategies adopted to counter the adverse impact. A review of administrative and clinical policy changes adopted at the tertiary cancer center to combat COVID pandemic and resume cancer surgical services were performed. A retrospective comparative analysis of cancer out-patient census during COVID pandemic affected year and the preceding normal year along with cancer surgery data audit for the same periods was performed to assess the impact of the pandemic on cancer surgery. In addition, COVID infection rates among cancer surgery patients and healthcare workers were evaluated. There was approximately a 50% reduction in cancer outpatient registrations during COVID pandemic affected year. A trend of increasing footfalls was noted with decreasing COVID intensity and opening of lockdowns. There was a 33% reduction in major elective surgery and a 41% reduction in emergency surgery performed during the COVID period. As far as cancer surgeries are concerned, there was a 12-50% reduction in volumes involving different subsites. Overall COVID positivity rates among cancer surgery patients was low (8.17%), and approximately 30% of healthcare workers involved in cancer surgery were tested positive for COVID during the study period. Results of the current study indicate a significant impact of COVID pandemic on cancer surgical services. There was a significant impact on outpatient visits and cancer surgery volumes. However, a multidisciplinary-coordinated team approach, effective administrative and policy implementation, adoption of revised surgical safety and anesthesia protocols, COVID screening, and testing protocols facilitated resumption of cancer surgical services without adverse impact on surgical outcomes.

Telemedicine as an Acceptable Model of Care in Advanced stage Cancer Patients in the Era of Coronavirus Disease 2019 - An Observational Study in a Tertiary Care Centre.

OBJECTIVES: The availability of routine care for patients with cancer during the coronavirus disease 2019 (COVID-19) pandemic has become challenging, and the use of telemedicine can be promising in this area. The objective of the study is to evaluate the feasibility of telemedicine-based palliative interventions in cancer patients. MATERIALS AND METHODS: This retrospective study was conducted in a tertiary care centre with 547 follow-up patients who used palliative medicine teleconsultation services. The following data were retrieved from the records: Patient's reason for the call, the main barriers to a hospital visit, the assistance given to them by the physician on the call and the patients' satisfaction with the service on a 4-point scale. The data were analysed using percentages for categorical variables and mean/standard deviation for quantitative variables. RESULTS: Out of the 547 patients, 462 (84.46%) utilised voice calling service, and the major reason for not visiting the hospital were cited to be fear of contracting COVID-19 (37.3%), inability to attend due to health constraints (7.13%) and issues with transportation (48.8%). The majority of the calls (63.62%) calls were regarding uncontrolled symptoms of the primary diseases. A total of 402 (73.49%) patients were very satisfied, and a total of 399 (72.94%) decided to continue to use this medium in the future as well. CONCLUSION: Telemedicine is a good modality for the assessment of chronic pain and providing symptomatic supportive care in patients with cancer in the COIVD-19 pandemic.

The COVID-19 pandemic: a new epoch and fresh challenges for cancer patients and caregivers-a descriptive cross-sectional study.

PURPOSE: Cancer patients and their caregivers are overwhelmed with features of uncertainty, fear, shock, worry, anxiety, sadness, and grief. To add on to their misery, the COVID-19 pandemic has severely afflicted the cancer care delivery. The study was conducted to observe the challenges faced by cancer patients and their caregivers and to formulate strategies for oncological setups to overcome those challenges. METHODS: After obtaining institutional ethical clearance, a descriptive cross-sectional study was conducted to observe the challenges faced by patients and their caregivers at the level of various domains (physical, logistic, psychological, socioeconomic, and spiritual) who visited the outpatient and inpatient department of cancer pain and palliative care unit. The results were expressed in absolute numbers. RESULTS: Major challenges encountered were suffering from physical symptoms like pain, nausea, vomiting, dyspnea (90%), postponement of cancer treatment (80%), fear of contracting COVID infection due to hospital visit (93.5%), lack of accommodation (70%), and lack of spiritual clarity and hope (50%). CONCLUSIONS: Major challenges faced by patients were in physical and psychological domains, and those by caregivers were in socioeconomic domains and handling physical symptoms of their patients. It is imperative to recognize and be cognizant of the challenges faced by cancer patients and their caregivers. Health care setups should formulate strategies to alleviate these challenges and provide holistic care to cancer patients. These strategies will hold in good stead for future pandemics also.

Complex and Challenging Surgery like CRS with HIPEC is Easible Midst the COVID 19 Pandemic: Experience from Tertiary Care Center in India.

BACKGROUND: Amidst the COVID pandemic, most guidelines have recommended delaying surgery and giving chemotherapy for with peritoneal surface malignancies. However, when all options are exhausted, complex surgery like CRS with HIPEC can be performed in select patients. METHOD: To facilitate these complex surgeries with maximum safety, RT-PCR test for COVID-19 was performed for each patient. Personal protective equipment including N95 masks and face shields was used. A number of OT personals were limited. Taking these steps minimized the risk of COVID-19 infections among healthcare workers and patients. CONCLUSION: After implementing these steps, we were able to perform complex CRS and HIPEC procedure during the pandemic and thus improve oncological outcomes.

A Questionnaire-based Survey on Challenges Faced and Strategies Adopted by Pain and Palliative Care Physicians Working in Oncology Setup During Novel COVID-19 Pandemic - A Descriptive Cross-sectional Study.

OBJECTIVES: Novel coronavirus (COVID-19) pandemic has brought to the fore various challenges faced by pain and palliative care physicians working in oncology setup all over the country. Cancer care has been afflicted a lot during the pandemic, with challenges faced by patients and their caregivers as well as the healthcare workers. The questionnaire based online survey was conducted to explore the personal challenges faced, strategies adopted and to compare the challenges between different oncology setups. MATERIALS AND METHODS: After obtaining institutional ethical clearance the online questionnaire prepared through Google forms was rolled out to pain and palliative care physicians working all over the country with the help of social media platforms. The results were expressed in absolute number, percentage and comparisons were made with the help of Fisher's exact test. RESULTS: Maximum challenges faced were the fear of carrying infection back home (91%), the possibility of attending to a COVID positive case in day to day clinical practice because of inadequate space and screening (62%) and limited services provided by NGO's during pandemic (71%). Strategies commonly adopted were the provision of necessary personal protective equipment (83%), the conduct of educational sessions for the task force members (67%), maximum utilization of available space in the hospital (85%) and stockpiling of necessary medications and equipment (75%). CONCLUSION: It is the need of the hour to formulate strong and effective strategies to overcome the challenges encountered by pain and palliative care physicians so that we are equipped in the future to deal with any kind of pandemics.

Single-dose oral ivermectin in mild and moderate COVID-19 (RIVET-COV): A single-centre randomized, placebo-controlled trial.

INTRODUCTION: Ivermectin is an antiparasitic drug which has in-vitro efficacy in reducing severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) viral load. Hence, Ivermectin is under investigation as a repurposed agent for treating COVID-19. METHODS: In this pilot, double blind, randomized controlled trial, hospitalized patients with mild-to-moderate COVID-19 were assigned to a single oral administration of an elixir formulation of Ivermectin at either 24 mg or 12 mg dose, or placebo in a 1:1:1 ratio. The co-primary outcomes were conversion of RT-PCR to negative result and the decline of viral load at day 5 of enrolment. Safety outcomes included total and serious adverse events. The primary outcomes were assessed in patients who had positive RT-PCR at enrolment (modified intention-to-treat population). Safety outcomes were assessed in all patients who received the intervention (intention-to-treat population). RESULTS: Among the 157 patients randomized, 125 were included in modified intention-to-treat analysis. 40 patients each were assigned to Ivermectin 24 mg and 12 mg, and 45 patients to placebo. The RT-PCR negativity at day 5 was higher in the two Ivermectin arms but failed to attain statistical significance (Ivermectin 24 mg, 47.5%; 12 mg arm, 35.0%; and placebo arm, 31.1%; p-value = 0.30). The decline of viral load at day 5 was similar in each arm. No serious adverse events occurred. CONCLUSIONS: In patients with mild and moderate COVID-19, a single oral administration of Ivermectin did not significantly increase either the negativity of RT-PCR or decline in viral load at day 5 of enrolment compared with placebo.
