Sciences Library and the GW Covid-19 Incident Management Intelligence Unit
- Multiple states set single day records as case counts and positivity rates increase:
- Florida breaks single day record for third day in a row
- In Arizona, health officials also reported a record, with 2,577 current
- Texas set a record for coronavirus-related hospitalizations for the 16th day in a row on Saturday, with 5,523 patients being treated. Following a record single-day increase of COVID-19 cases in the state, TX Gov. Greg Abbott has paused further phases of the state's reopening plan and halted elective surgeries in four counties.
- A retrospective case-control study of patients with severe COVID-19 found a non-statistically significant lower mortality in the treatment group (52% versus 62.1% P = 0.09). When excluding
intubated patients, there was statistically significant lower mortality in patients treated with tocilizumab (6% vs.
27% P = 0.024).
- A 21-day observational study published in CHEST found that in tocilizumab-treated patients, oxygenation
and inflammatory biomarkers (hsCRP and IL-6) improved. However, sIL-2R and D-Dimer levels increased. Survival of
severe patients treated with tocilizumab was similar to non-severe patients: (83% vs 91%; p=0.11).
- A retrospective, observational cohort study found that in patients with severe COVID-19 pneumonia,
treatment with tocilizumab, whether administered intravenously or subcutaneously, might reduce the risk of
invasive mechanical ventilation or death
- Tocilizumab treatment was associated with a reduced risk of invasive mechanical ventilation or death
(adjusted hazard ratio 0·61, 95% CI 0·40–0·92; p=0·020).
- Follow-up for outcomes was brief - between 4-18
- Colchicine: Results from the GRECCO-19 randomized clinical trial found that participants who received
colchicine had statistically significantly improved time to clinical deterioration. There were no significant
differences in high-sensitivity cardiac troponin or C-reactive protein
- As mentioned last week, preliminary results from the RECOVERY trial show mortality reduction in patients
on oxygen or invasive mechanical ventilation who received dexamethasone 6 mg given once daily for up to ten days
vs. usual case. Overall, 454 (21.6%) patients allocated dexamethasone and 1065 (24.6%) patients allocated usual
care died within 28 days (age-adjusted rate ratio [RR] 0.83; 95% confidence interval [CI] 0.74 to 0.92;
P<0.001). There was no benefit to people without an oxygen requirement and may be a trend towards harm in
- MGH FLARE summary of evidence on steroids, ARDS, and COVID-19 suggest clinicians should “strongly
consider the use of dexamethasone in their COVID-19 patients with an oxygen requirement or hypoxemic respiratory
- A study looking at the association between renin–angiotensin system inhibitors and COVID-19
complications found the risk of admission to ICU or death prior to ICU admission was 73 times higher
(odds ratio 1.73, 95% confidence interval 1.02–2.93) in patients treated at baseline with a RASI than in
patients not treated with this drug class. This association was confirmed when the analysis was restricted to
patients treated with antihypertensive agents. Further study on this potential link needs to be done. This is
counter to the finding of the earlier study in NEJM that found no increased risk of death in patients on
ACEs/ARBs - a study that was retracted.
- Mounting clues suggest the coronavirus might trigger diabetes: There have been reports of patients who
spontaneously developed diabetes after being infected with SARS-CoV-2. A recent experimental study in
miniature lab-grown pancreases published last week suggests that the virus might trigger diabetes by damaging
the cells that control blood An online registry has been developed to evaluate COVID-19 related diabetes
- CDC updates, expands list of people at risk of severe COVID-19 illness:
- Removes age threshold (over 65) from the older adult classification, now stating that risk increases
steadily as you
- Conditions the increase risk for severe COVID-19 disease: Chronic kidney disease; COPD; Obesity (BMI of
30 or higher); Immunocompromised state from solid organ transplant; Serious heart conditions, such as
heart failure, coronary artery disease, or cardiomyopathies; Sickle cell disease; Type 2 diabetes
- New Bill introduced this week - the Equal Access to Care Act- would allow licensed
providers to use telehealth in any state to treat patients in any location for up to 180 days after the end of
Public health interventions
- A JAMA article studying health disparities found that African American participants, men, and people
younger than 55 years were less likely to know how the disease is spread, were less likely to know the symptoms
of coronavirus disease 2019, washed their hands less frequently, and left the home more
- A JAMA Cardiology study found out-of-hospital cardiac arrests and deaths during the COVID-19 pandemic
significantly increased compared with the same period the previous year and were associated with older age,
nonwhite race/ethnicity, hypertension, diabetes, physical limitations, and nonshockable presenting rhythms
- A telemedicine system reduced the risks of delayed hospitalization for COVID-19 patients quarantined at home due
to disease Through the comparison of monitored symptoms between hospitalized and non-hospitalized patients,
this study found the prolonged persistence and deterioration of fever, dyspnea, lack of strength, and
muscle soreness to be diagnostic for identifying patients for hospitalization.
Updates for the District of Columbia
- As of June 28th, the District’s overall positive case total was 10,248 with 550
- DC’s positivity rate has risen from low of 2% on 6/12 to 4.4% on 6/20. However, this may be a
reflection of the drop in number of residents tested: 3498 on 6/12 down to only 745 on 6/20.
- Hospital occupancy is 78 % in DC; the proportion of occupancy due to COVID-19 continues to
decrease (126 of 1,944 total) and ventilator utilization remains below 50%.
- Sharp increases in cases in the Latino community: 42.6% of Latinos in the Baltimore-DC metro area who
were tested for SARS-CoV-2 were positive- a much higher proportion than for any other racial/ethnic group
possibly reflecting higher exposure rates and/or barriers to
