Sickle cell disease is associated with worse long-term bone health than that of the general population, and SCD patients are more likely to experience vitamin D [25(OH)D] deficiency. Oral vitamin D3 supplementation can achieve protective levels in children with sickle cell disease, and a daily dose was able to achieved optimal blood levels, according to a report published online in Bone.

The researchers performed a prospective, longitudinal, single-center study of 80 children with SCD. They collected demographic, clinical, and management data, as well as 25(OH)D levels. Bone densitometries (DXA) were also collected.

Among the 80 patients were included in the analysis, there were significant differences between the means of 25(OH)D levels based on whether the patient started prophylactic treatment as an infant or not (35.7 vs. 27.9 ng/mL, respectively [P = .014]), according to the researchers.

They also found that, in multivariate analysis, an oral 800 IU daily dose of vitamin D3 was shown to be a protective factor (P = .044) in reaching optimal 25(OH)D blood levels (≥ 30 ng/mL).

Kaplan-Meier analysis showed that those patients younger than 10 years of age reached optimal levels significantly earlier than older patients when on supplementation (P = .002), as did those patients who were not being treated with hydroxyurea (P = .039), the researchers wrote.

Significant differences were seen between the mean bone mineral density in both DXAs performed when comparing suboptimal vs. optimal blood levels of 25(OH)D (0.54 g/cm² vs. 0.64 g/cm2, respectively, P = .001), for the initial DXA, and for the most recent DXA (0.59 g/cm² vs. 0.77 g/cm², respectively, P = .044). “VitD3 prophylaxis is a safe practice in SCD. It is important to start this prophylactic treatment when the child is an infant. The daily regimen with 800 IU could be more effective for reaching levels ≥ 30 ng/mL, and, especially in preadolescent and adolescent patients, we should raise awareness about the importance of good bone health,” the authors concluded.

The authors reported that they had no conflicts of interest.

Coronavirus disease 2019 (COVID-19) is a viral illness caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), currently causing a pandemic affecting many countries around the world, beginning in December 2019 and spreading rapidly on a global scale since. Globally, its burden has been increasing rapidly, with more than 1.2 million people testing positive for the illness and 123,000 people losing their lives, as per April 15th’s WHO COVID-19 Situation Report.¹ These numbers are increasing with each passing day. Clinically, SARS-CoV-2 has a highly variable course, ranging from mild disease manifested as a self-limited illness (seen in younger and healthier patients) to severe pneumonia/ARDS and multiorgan failure with intravascular coagulopathy.²

In this article, we intend to investigate and establish a comprehensive review of COVID-19–associated coagulopathy mechanisms, laboratory findings, and current management guidelines put forth by various societies globally. 
 

Mechanism of coagulopathy

COVID-19–associated coagulopathy has been shown to predispose to both arterial and venous thrombosis through excessive inflammation and hypoxia, leading to activation of the coagulation cascade and consumption of coagulation factors, resulting in microvascular thrombosis.³ Though the exact pathophysiology for the activation of this cascade is not known, the proposed mechanism has been: endothelial damage triggering platelet activation within the lung, leading to aggregation, thrombosis, and consumption of platelets in the lung.^2,5,6

Fox et al. noted similar coagulopathy findings of four deceased COVID-19 patients. Autopsy results concluded that the dominant process was diffuse alveolar damage, notable CD4+ aggregates around thrombosed small vessels, significant associated hemorrhage, and thrombotic microangiopathy restricted to the lungs. The proposed mechanism was the activation of megakaryocytes, possibly native to the lung, with platelet aggregation, formation of platelet-rich clots, and fibrin deposition playing a major role.⁴

It has been noted that diabetic patients are at an increased risk of vascular events and hypercoagulability with COVID-19.⁷ COVID-19 can also cause livedo reticularis and acrocyanosis because of the microthrombosis in the cutaneous vasculature secondary to underlying coagulopathy, as reported in a case report of two U.S. patients with COVID-19.⁸

Clinical and laboratory abnormalities

A recent study reported from Netherlands by Klok et al. analyzed 184 ICU patients with COVID-19 pneumonia and concluded that the cumulative incidence of acute pulmonary embolism (PE), deep vein thrombosis (DVT), ischemic stroke, MI, or systemic arterial embolism was 31% (95% confidence interval, 20%-41%). PE was the most frequent thrombotic complication and was noted in 81% of patients. Coagulopathy, defined as spontaneous prolongation of prothrombin time (PT) > 3s or activated partial thromboplastin time (aPTT) > 5s, was reported as an independent predictor of thrombotic complications.³

Hematologic abnormalities that were noted in COVID-19 coagulopathy include: decreased platelet counts, decreased fibrinogen levels, elevated PT/INR, elevated partial thromboplastin time (PTT), and elevated d-dimer.^9,10 In a retrospective analysis⁹ by Tang et al., 71.4% of nonsurvivors and 0.6% of survivors had met the criteria of disseminated intravascular coagulation (DIC) during their hospital stay. Nonsurvivors of COVID-19 had statistically significant elevation of d-dimer levels, FDP levels, PT, and aPTT, when compared to survivors (P < .05). The overall mortality in this study was reported as 11.5%.⁹ In addition, elevated ^d-dimer, fibrin and fibrinogen degradation product (FDP) levels and longer PT and aPTT were associated with poor prognosis.

Thus, d-dimer, PT, and platelet count should be measured in all patients who present with COVID-19 infection. We can also suggest that in patients with markedly elevated d-dimer (three- to fourfold increase), admission to hospital should be considered even in the absence of severe clinical symptoms.¹¹

COVID-19 coagulopathy management

In a retrospective study⁹ of 449 patients with severe COVID-19 from Wuhan, China, by Tang et al., 99 patients mainly received low-weight molecular heparin (LMWH) for 7 days or longer. No difference in 28-day mortality was noted between heparin users and nonusers (30.3% vs. 29.7%; P = .910). A lower 28-day mortality rate was noted in heparin patients with sepsis-induced coagulopathy score of ≥4.0 (40.0% vs. 64.2%; P = .029) or a d-dimer level greater than sixfold of upper limit of normal, compared with nonusers of heparin.¹²

Another small study of seven COVID-19 patients with acroischemia in China demonstrated that administering LMWH was successful at decreasing the d-dimer and fibrinogen degradation product levels but noted no significant improvement in clinical symptoms.¹³

Recently, the International Society of Thrombosis and Hemostasis and American Society of Hematology published recommendations and guidelines regarding the recognition and management of coagulopathy in COVID-19.¹¹ Prophylactic anticoagulation therapy with LMWH was recommended in all hospitalized patients with COVID-19, provided there was an absence of any contraindications (active bleeding, platelet count less than 25 x 10⁹/L and fibrinogen less than 0.5 g/dL). Anticoagulation with LMWH was associated with better prognosis in severe COVID-19 patients and in COVID-19 patients with markedly elevated d-dimer, as it also has anti-inflammatory effects.¹² This anti-inflammatory property of heparin has been documented in previous studies but the underlying mechanism is unknown and more research is required.^14,15

Despite coagulopathy being noticed with cases of COVID-19, bleeding has been a rare finding in COVID-19 infections. If bleeding is noted, recommendations were made to keep platelet levels greater than 50 x10⁹/L, fibrinogen less than 2.0 g/L, and INR [international normalized ratio] greater than 1.5.¹¹ Mechanical thromboprophylaxis should be used when pharmacologic thromboprophylaxis is contraindicated.¹⁶

COVID-19 patients with new diagnoses of venous thromboembolism (VTE) or atrial fibrillation should be prescribed therapeutic anticoagulation. Patients who are already on anticoagulation for VTE or atrial fibrillation should continue their therapy unless the platelet count is less than 30-50x10⁹/L or if the fibrinogen is less than 1.0 g/L.¹⁶

Conclusion

Coagulopathies associated with COVID-19 infections have been documented in several studies around the world, and it has been shown to be fatal in some cases. Despite documentation, the mechanism behind this coagulopathy is not well understood. Because of the potentially lethal complications associated with coagulopathies, early recognition and anticoagulation is imperative to improve clinical outcomes. These results are very preliminary: More studies are required to understand the role of anticoagulation and its effect on the morbidity and mortality associated with COVID-19–associated coagulopathy.

A recent study reported from Netherlands by Klok et al. analyzed 184 ICU patients with COVID-19 pneumonia and concluded that the cumulative incidence of acute pulmonary embolism (PE), deep vein thrombosis (DVT), ischemic stroke, MI, or systemic arterial embolism was 31% (95% confidence interval, 20%-41%). PE was the most frequent thrombotic complication and was noted in 81% of patients. Coagulopathy, defined as spontaneous prolongation of prothrombin time (PT) > 3s or activated partial thromboplastin time (aPTT) > 5s, was reported as an independent predictor of thrombotic complications.³

Hematologic abnormalities that were noted in COVID-19 coagulopathy include: decreased platelet counts, decreased fibrinogen levels, elevated PT/INR, elevated partial thromboplastin time (PTT), and elevated d-dimer.^9,10 In a retrospective analysis⁹ by Tang et al., 71.4% of nonsurvivors and 0.6% of survivors had met the criteria of disseminated intravascular coagulation (DIC) during their hospital stay. Nonsurvivors of COVID-19 had statistically significant elevation of d-dimer levels, FDP levels, PT, and aPTT, when compared to survivors (P < .05). The overall mortality in this study was reported as 11.5%.⁹ In addition, elevated ^d-dimer, fibrin and fibrinogen degradation product (FDP) levels and longer PT and aPTT were associated with poor prognosis.

Thus, d-dimer, PT, and platelet count should be measured in all patients who present with COVID-19 infection. We can also suggest that in patients with markedly elevated d-dimer (three- to fourfold increase), admission to hospital should be considered even in the absence of severe clinical symptoms.¹¹

COVID-19 coagulopathy management

In a retrospective study⁹ of 449 patients with severe COVID-19 from Wuhan, China, by Tang et al., 99 patients mainly received low-weight molecular heparin (LMWH) for 7 days or longer. No difference in 28-day mortality was noted between heparin users and nonusers (30.3% vs. 29.7%; P = .910). A lower 28-day mortality rate was noted in heparin patients with sepsis-induced coagulopathy score of ≥4.0 (40.0% vs. 64.2%; P = .029) or a d-dimer level greater than sixfold of upper limit of normal, compared with nonusers of heparin.¹²

Another small study of seven COVID-19 patients with acroischemia in China demonstrated that administering LMWH was successful at decreasing the d-dimer and fibrinogen degradation product levels but noted no significant improvement in clinical symptoms.¹³

Recently, the International Society of Thrombosis and Hemostasis and American Society of Hematology published recommendations and guidelines regarding the recognition and management of coagulopathy in COVID-19.¹¹ Prophylactic anticoagulation therapy with LMWH was recommended in all hospitalized patients with COVID-19, provided there was an absence of any contraindications (active bleeding, platelet count less than 25 x 10⁹/L and fibrinogen less than 0.5 g/dL). Anticoagulation with LMWH was associated with better prognosis in severe COVID-19 patients and in COVID-19 patients with markedly elevated d-dimer, as it also has anti-inflammatory effects.¹² This anti-inflammatory property of heparin has been documented in previous studies but the underlying mechanism is unknown and more research is required.^14,15

Despite coagulopathy being noticed with cases of COVID-19, bleeding has been a rare finding in COVID-19 infections. If bleeding is noted, recommendations were made to keep platelet levels greater than 50 x10⁹/L, fibrinogen less than 2.0 g/L, and INR [international normalized ratio] greater than 1.5.¹¹ Mechanical thromboprophylaxis should be used when pharmacologic thromboprophylaxis is contraindicated.¹⁶

COVID-19 patients with new diagnoses of venous thromboembolism (VTE) or atrial fibrillation should be prescribed therapeutic anticoagulation. Patients who are already on anticoagulation for VTE or atrial fibrillation should continue their therapy unless the platelet count is less than 30-50x10⁹/L or if the fibrinogen is less than 1.0 g/L.¹⁶

Conclusion

Coagulopathies associated with COVID-19 infections have been documented in several studies around the world, and it has been shown to be fatal in some cases. Despite documentation, the mechanism behind this coagulopathy is not well understood. Because of the potentially lethal complications associated with coagulopathies, early recognition and anticoagulation is imperative to improve clinical outcomes. These results are very preliminary: More studies are required to understand the role of anticoagulation and its effect on the morbidity and mortality associated with COVID-19–associated coagulopathy.

Differences in COVID-19-related death rates between people of white and Asian ancestry may be partly explained by documented ethnic/racial differences in risk for blood clotting and pulmonary thrombotic events, investigators propose.

“Our novel findings demonstrate that COVID-19 is associated with a unique type of blood clotting disorder that is primarily focused within the lungs and which undoubtedly contributes to the high levels of mortality being seen in patients with COVID-19,” said James O’Donnell, MB, PhD, director of the Irish Centre for Vascular Biology at the Royal College of Surgeons in Ireland.

Dr. O’Donnell and colleagues studied pulmonary effects and outcomes of 83 patients admitted to St. James Hospital in Dublin, and found evidence to suggest that the diffuse, bilateral pulmonary inflammation seen in many patients with severe COVID-19 infections may be caused by a pulmonary-specific vasculopathy they label “pulmonary intravascular coagulopathy” (PIC), an entity distinct from disseminated intravascular coagulopathy (DIC).

“Given that thrombotic risk is significantly impacted by race, coupled with the accumulating evidence that coagulopathy is important in COVID-19 pathogenesis, our findings raise the intriguing possibility that pulmonary vasculopathy may contribute to the unexplained differences that are beginning to emerge highlighting racial susceptibility to COVID-19 mortality,” they wrote in a study published online in the British Journal of Haematology.
 

Study flaws harm conclusions

But critical care specialists who agreed to review and comment on the study for MDedge News said that it has significant flaws that affect the ability to interpret the findings and “undermine the conclusions reached by the authors.”

“The underlying premise of the study is that there are racial and ethnic differences in the development of venous thromboembolism that may explain the racial and ethnic differences in outcomes from COVID-19,” J. Daryl Thornton, MD, MPH, a fellow of the American Thoracic Society and associate professor of pulmonary, critical care, and sleep medicine at Case Western Reserve University, Cleveland, said in an interview. “This is an interesting hypothesis and one that could be easily tested in a well-designed study with sufficient representation from the relevant racial and ethnic groups. However, this study is neither well designed nor does it have sufficient racial and ethnic representation.”

Elliott R. Haut, MD, PhD, associate professor of surgery, anesthesiology and critical care medicine at Johns Hopkins Medicine, Baltimore, said in an interview that the study is “mediocre” and has the feel of a paper rushed to press.

“It talks about their theory that race, ethnicity, have an effect on venous thromboembolism, and that’s a pretty well-known fact. No one’s a hundred percent sure why that is, but certainly there are tons and tons of papers that show that there are groups that are at higher risk than others,” he said. “Their idea that this is caused by this pulmonary inflammation, that is totally a guess; there is no data in this paper to support that.”

Dr. Thornton and Dr. Haut both noted that the authors don’t define how race and ethnicity were determined and whether patients were asked to provide it, and although they mention the racial/ethnic breakdown once, subsequent references are to entire cohort are as “Caucasian.”

They also called into question the value of comparing laboratory data across continents in centers with different testing methods and parameters, especially in a time when the clinical picture changes so rapidly.
 

Coagulation differences

Dr. O’Donnell and colleagues noted that most studies of COVID-19-associated coagulopathy published to date have been with Chinese patients.

“This is important because race and ethnicity have major effects upon thrombotic risk. In particular, epidemiological studies have shown that the incidence of venous thromboembolism (VTE) is approximately three to fourfold lower in Chinese compared to Caucasian individuals. Conversely, VTE risk is significantly higher in African-Americans compared to Caucasians,” they wrote.

Because of the lower risk of VTE in the Chinese population, thromboprophylaxis with low-molecular-weight heparin (LMWH) or other agents is less frequently used in Chinese hospitals than in hospitals with predominantly non-Asian patients, they noted.

To see whether the were differences in coagulopathy between Chinese and white patients, the researchers enrolled 55 men and 28 women, median age 64, who were admitted to St. James Hospital with COVID-19 infections from March 13 through April 10, 2020. The cohort included 67 patients of white background, 10 of Asian ancestry, 5 of African ethnicity, and 1 of Latino/Hispanic ancestry.

Of the 83 patients, 67 had comorbidities at admission. At the time of the report, 50 patients had fully recovered and were discharged, 20 remained in the hospital, and 13 had died. In all, 50 patients were discharged without needing ICU care, 23 were admitted to the ICU, and 10 required ICU but were deemed “clinically unsuitable” for ICU admission.

Although the patients had normal prothrombin time (PT) and normal activated partial thromboplastin time (APTT), plasma d-dimer levels were significantly elevated and were above the range of normal in two-thirds of patients on admission.

Despite the increased d-dimer levels, however, there was no evidence of DIC as defined by the International Society of Thrombosis and Hemostasis Scientific and Standardization committee (ISTH SSC) guidelines. Platelet counts were in the normal range in 83.1% of patients, and only five had counts less than 100 x 109/L at admission. Fibrinogen levels were also elevated, as were C-reactive protein levels, both likely indicating an acute phase response.

“Thus, despite the fact that thrombotic risk is much higher in Caucasian patients and the significant elevated levels of d-dimers observed, overt DIC as defined according to the ISTH SSC DIC score was present in none of our COVID-19 patients at time of admission. Nevertheless, our data confirm that severe COVID-19 infection is associated with a significant coagulopathy in Caucasian patients that appears to be similar in magnitude to that previously reported in the original Chinese cohorts,” they wrote.

When they compared patients who required ICU admission for ventilator support and those who died with patients who were discharged without needing ICU support, they found that survivors were younger (median age 60.2 vs. 75.2 years), and that more critically ill patients were more likely to have comorbidities.

They also found that patients with abnormal coagulation parameters on admission were significantly more likely to have poor prognosis (P = .018), and that patients in the adverse outcomes group had significantly higher fibrinogen and CRP levels (P = .045 and .0005, respectively).

There was no significant difference in PT between the prognosis groups at admission, but by day 4 and beyond PT was a median of 13.1 vs. 12.5 seconds in the favorable outcomes groups (P = .007), and patients with poor prognosis continued to have significantly higher d-dimer levels. (P = .003)

“Cumulatively, these data support the hypothesis that COVID-19–associated coagulopathy probably contributes to the underlying pulmonary pathogenesis,” the researchers wrote.

They noted that the angiotensin converting enzyme 2 (ACE-2) receptor that COVID-19 uses to enter cells is expressed on both type II pneumocytes and vascular endothelial cells within the lung, suggesting that the coagulopathy may be related to direct pulmonary endothelial cell infection , activation, and/or damage, and to the documented cytokine storm that can affect thrombin generation and fibrin deposition within the lungs.

“In the context of this lung-centric vasculopathy, we hypothesize that the refractory acute respiratory distress syndrome phenotype observed in severe COVID-19 is due to concurrent ‘double-hit’ pathologies targeting both ventilation (V) and perfusion (Q) within the lungs where alveoli and pulmonary microvasculature exist in close anatomical juxtaposition,” they wrote.

The investigators noted that larger randomized trials will be needed to determine whether more aggressive anti-coagulation and/or targeted anti-inflammatory therapies could effectively treated PIC in patients with severe COVID-19.

The study was supported by the Wellcome Trust and the Health Research Board Health Service and the Research and Development Division, Northern Ireland. Dr. O’Donnell disclosed speakers bureau activities, advisory board participation, and research grants from multiple companies. The other doctors had no relevant conflicts of interest to disclose.

Cancer type, stage, and recent treatment may affect outcomes of COVID-19 in cancer patients, according to a study of patients from China.

The data showed that patients with hematologic malignancies and those with metastatic cancers had higher risks of developing severe or critical COVID-19 symptoms, being admitted to the ICU, requiring ventilation, and dying.

On the other hand, patients with nonmetastatic cancer had outcomes comparable to those of noncancer patients with COVID-19.

Similarly, cancer patients who had recently undergone surgery or received immunotherapy were more likely to have poor outcomes, whereas cancer patients treated with radiotherapy had outcomes similar to those of noncancer COVID-19 patients.

Hongbing Cai, MD, of Zhongnan Hospital of Wuhan University in China, presented these results at the AACR virtual meeting I. The results also were published in Cancer Discovery.
 

Cancer vs. noncancer patients

The study included 105 cancer patients with COVID-19 who were treated from Jan. 1 to Feb. 24, 2020, at 14 hospitals in Wuhan, China. Patients had lung (20.95%), gastrointestinal (12.38%), breast (10.48%), and thyroid cancers (10.48%) as well as hematologic malignancies (8.57%). Dr. Cai and colleagues matched the COVID-19 cancer patients to 536 COVID-19 patients without cancer. Patients were matched by hospital, duration of hospitalization, and age.

“COVID-19 patients with cancer had higher risks of all severe outcomes,” Dr. Cai noted.

Compared with noncancer patients, the cancer patients had a higher risk of:

• Severe or critical COVID-19 symptoms – odds ratio, 2.79 (P < .01).
• Being admitted to the ICU – OR, 2.84 (P < .01).
• Requiring invasive mechanical ventilation – OR, 14 (P < .01).
• Death – OR, 2.34 (P = .03).

Cancer type and stage

Dr. Cai noted that outcomes were the worst among patients with hematologic malignancies and those with metastatic cancer (stage IV).

Compared with patients without cancer, those with hematologic malignancies had a higher risk of:

• Severe/critical symptoms – OR, 10.61 (P < .01).
• ICU admission – OR, 9.66 (P < .01).
• Invasive mechanical ventilation – OR, 38 (P < .01).
• Death – OR, 9.07 (P = .01).

Compared with patients without cancer, those with metastatic cancer had a higher risk of:

• Severe/critical symptoms – OR, 5.97 (P < .01).
• ICU admission – OR, 6.59 (P < 0.01).
• Invasive mechanical ventilation – OR, 55.42 (P < .01).
• Death – OR, 5.58 (P = .01).

On the other hand, outcomes in patients with nonmetastatic cancer were not significantly different from outcomes in patients without cancer (P > .05 for all outcomes).
 

Cancer treatment

The treatments cancer patients received within 40 days before the onset of COVID-19 symptoms were radiotherapy (12.26%), chemotherapy (14.15%), surgery (7.62%), targeted therapies (3.81%), and immunotherapy (5.71%).

Compared with patients without cancer, those who received immunotherapy had a higher risk of:

• Severe/critical symptoms – OR, 10.61 (P < .01).
• Death – OR, 9.07 (P = .04).

Patients who underwent surgery had a higher risk of:

• Severe/critical symptoms – OR, 8.84 (P < .01).
• ICU admission – OR, 7.24 (P = .02).
• Invasive mechanical ventilation – OR, 44.33 (P < .01).

Conversely, outcomes in cancer patients who received radiotherapy were not significantly different from outcomes in patients without cancer (P > .10 for all).

These results suggest that “postponing surgery should be considered in outbreak areas,” Dr. Cai said, adding that scheduled radiotherapy can go ahead but with “intensive protection and surveillance.”

Dr. Cai said it remains to be seen whether patients with early-stage cancer need to postpone their treatments during the COVID-19 pandemic or whether immunotherapy aggravates severe outcomes in cancer patients with COVID-19. For now, she said, cancer patients should have individualized treatment plans based on their tumor type and stage.

Dr. Cai disclosed no conflicts of interest. This study was supported by the National Natural Science Foundation of China, the Singapore Ministry of Health’s National Medical Research Council, the National Institutes of Health/National Heart, Lung, and Blood Institute, and the Xiu Research Fund.

Unless global investments are made to improve care worldwide, 11.1 million children will die from cancer over the next 30 years; 9.3 million of them (84%) will be in low- and lower-middle–income countries, according to a report in Lancet Oncology.

The report suggests that one in two new cases of childhood cancer are undiagnosed in low- and middle-income countries. If that trend continues, the number of children with cancer who are never diagnosed over the next 3 decades will exceed the number of those who are diagnosed.

Childhood cancer “is not complex, expensive, difficult to diagnose, or complicated to treat,” yet there’s a “worldwide inequity and a bleak picture for children with cancer” in low-income and middle-income countries, according to the report authors. The authors are 44 oncologists, pediatricians, and global health experts from around the world, led by Rifat Atun, MD, a professor of global health systems at Harvard University in Boston.

“For too long, there has been a widespread misconception that caring for children with cancer in low- and middle-income countries is expensive, unattainable, and inappropriate because of competing health priorities. Nothing could be further from the truth,” Dr. Atun said in a statement.

Dr. Atun and colleagues argued that the burden of childhood cancer “could be vastly reduced with new funding to scale up cost-effective interventions.” In fact, the authors estimated that scaling up interventions could prevent 6.2 million childhood cancer deaths between 2020 and 2050.

The reduction in deaths would translate to 318.4 million life-years gained, which would, in turn, translate to a global lifetime productivity gain of $2,580 billion, four times greater than the cumulative cost of $594 billion. This would mean a net return of $3 for every $1 spent.

Potential funders include governments, professional organizations, philanthropic groups, and industry, according to the authors. They also laid out the following six-pronged framework on how to proceed:

• Include childhood cancer in universal health coverage.
• Develop national cancer control plans for low-income and middle-income countries.
• End out-of-pocket costs for childhood cancer.
• Establish national and regional cancer networks to increase access to care.
• Expand population-based cancer registries to include children.
• Invest in research and innovations in low-income and middle-income countries.

“Success will be attained through political leadership, global solidarity, collective action, inclusive participation of all major stakeholders, and alignment of national and global efforts to expand access to effective and sustainable care for children with cancer,” the authors wrote.

No funding sources were reported. The authors didn’t have any disclosures.

My pathology lab once faced a daily flood of colon polyps, pap smears, and prostate biopsies. Suddenly, our work has dried up. The coronavirus pandemic has cleared out operating rooms and clinics across the country. Endoscopy and radiology suites have gone dark.

Pathology is largely driven by mass screening programs, and the machinery of screening has grinded to a halt during the COVID-19 pandemic. The American Cancer Society currently recommends that “no one should go to a health care facility for routine cancer screening at this time.”

But malignancies are still growing and spreading even though a great deal of medical care is on hold. The most urgent cancer care is still taking place; the risks of delaying treatment for patients with advanced or symptomatic cancer are obvious—these tumors can cause severe pain and life-threatening complications.

But that leaves us with a more complex and uncomfortable question: Will the pause in screening ultimately leave patients with tiny, asymptomatic cancers or precursor lesions worse off? What will a delay mean for those with ductal carcinoma in situ or small breast cancers? What’s the long-term effect of all those dysplastic nevi and early melanoma left unexcised by dermatologists? Perhaps more troubling, what about the spreading kidney cancer that may have turned up as an incidental finding on a CT scan?
 

COVID-19: A natural experiment

For many years, we’ve been dealing with the other side of the screening question: overdiagnosing and treating cancers that would probably never harm the patient. Overdiagnosis has been on a decades-long rise due to organized screening like PSA testing and mammography, as well as through ad hoc detection from heavier use of medical imaging. All of these have been disrupted by the pandemic.

Because the correlation between medical interventions and cancer overdiagnosis is clear, we can safely assume that overdiagnosis will decline during the pandemic. But what will be the net effect? Early detection of cancer undoubtedly saves some lives, but how many and at what cost has been a seemingly intractable debate.

Until now.

The coronavirus outbreak will be a natural experiment like no other. Economists and epidemiologists love to study “natural experiments” – systemic shocks that shed light on a complex phenomenon.

The unexpected nationwide delay in screening will undoubtedly inform the debate on overdiagnosis. For one, we can learn whether less intensive screening leads to more advanced cancers. Because screening will probably return to normal at different times across the country, we can almost simulate a randomized trial. Will this transformative data be a silver lining to this awful time?
 

The pressure to ‘fight’

The pandemic has also raised a question about cancer screening that goes beyond data: Why has the loud epidemic of coronavirus so thoroughly trumped cancer’s silent one? To me, the necessary urgency of our coronavirus response stands in stark contrast to the overly aggressive public health messaging used for cancer screening.

The tools used to fight the coronavirus epidemic have been forceful. We’re all diligently washing our hands and staying inside. We’re making sacrifices in our jobs and personal lives to stop the virus’ spread.

Cancer screening has similarly been touted as dogma – an urgent public health intervention that only a fool would turn down. The American Cancer Society once ran an infamous advertisement suggesting that if you decline mammography, you “need more than your breasts examined.” Even today, well-intentioned organizations run cancer screening drives pushing people to pledge to “get screened now.” It is no surprise, then, that I have had patients and family members confide in me that they feel guilty about not pursuing all of their recommended screening tests. The thought of anyone feeling like they caused their own cancer appalls me.

This pressure extends into the clinic. In many practices, primary care doctors are evaluated based on how many patients “comply” with screening recommendations. There seems to be a relentless drive to reach 100% screening penetration. These oversimplified tactics run counter to the shared decision making and informed consent we profess to value in medicine.

The tricky thing about cancer screening is that because most people will never develop the cancer being screened for, we know that most people can also never be helped by it. This doesn’t make screening useless, just as washing your hands can help even if it doesn’t guarantee that you won’t catch coronavirus. We know that some individuals benefit, which we detect at the population level. Overdiagnosis arises in the same way, as a phenomenon detected within populations and not individuals. These aspects of screening are what has led to cancer being viewed as a “societal disease” requiring a uniform response – 100% screening compliance.
 

Metaphors of war

These assumptions fall apart now that we are facing a real societal disease, an infectious disease outbreak. Coronavirus has made us reflect on what actions individuals should take in order to protect others. But cancer is not a contagion. When we decide whether and how to screen, we make intimate decisions affecting primarily ourselves and our family – not society at large.

Countless articles have been written about the use of metaphor in cancer, perhaps most famously by essayist and breast cancer patient Susan Sontag. Sontag and others have been critical of the rampant use of war metaphors in the cancer community. Wars invoke sacrifice, duty, and suffering. The “battle” against coronavirus really puts the “war on cancer” in perspective. These pandemic weeks have terrified me. I have been willing to do anything to protect myself and others. They’ve also exhausted me. We can’t be at war forever.

When this current war ends, will the “war on cancer” resume unchanged? Screening will no doubt begin again, hopefully improved by data from the coronavirus natural experiment. But I wonder whether we will tolerate the same kinds of public health messages – and whether we should – having now experienced an infectious disease outbreak where our actions as individuals really do have an impact on the health of others.

After feeling helpless, besieged, and even guilt-ridden during the pandemic, I think many people would appreciate regaining a sense of control over other aspects of their health. Cancer screening can save lives, but it’s a choice we should make for ourselves based on an understanding of the trade-offs and our own preferences. When screening restarts, I hope its paternalistic dogma can be replaced by nuanced, empowering tactics more appropriate for peacetime.

The American Cancer Society once ran an infamous advertisement suggesting that if you decline mammography, you “need more than your breasts examined.” Even today, well-intentioned organizations run cancer screening drives pushing people to pledge to “get screened now.” It is no surprise, then, that I have had patients and family members confide in me that they feel guilty about not pursuing all of their recommended screening tests. The thought of anyone feeling like they caused their own cancer appalls me.

This pressure extends into the clinic. In many practices, primary care doctors are evaluated based on how many patients “comply” with screening recommendations. There seems to be a relentless drive to reach 100% screening penetration. These oversimplified tactics run counter to the shared decision making and informed consent we profess to value in medicine.

The tricky thing about cancer screening is that because most people will never develop the cancer being screened for, we know that most people can also never be helped by it. This doesn’t make screening useless, just as washing your hands can help even if it doesn’t guarantee that you won’t catch coronavirus. We know that some individuals benefit, which we detect at the population level. Overdiagnosis arises in the same way, as a phenomenon detected within populations and not individuals. These aspects of screening are what has led to cancer being viewed as a “societal disease” requiring a uniform response – 100% screening compliance.
 

Metaphors of war

These assumptions fall apart now that we are facing a real societal disease, an infectious disease outbreak. Coronavirus has made us reflect on what actions individuals should take in order to protect others. But cancer is not a contagion. When we decide whether and how to screen, we make intimate decisions affecting primarily ourselves and our family – not society at large.

Countless articles have been written about the use of metaphor in cancer, perhaps most famously by essayist and breast cancer patient Susan Sontag. Sontag and others have been critical of the rampant use of war metaphors in the cancer community. Wars invoke sacrifice, duty, and suffering. The “battle” against coronavirus really puts the “war on cancer” in perspective. These pandemic weeks have terrified me. I have been willing to do anything to protect myself and others. They’ve also exhausted me. We can’t be at war forever.

When this current war ends, will the “war on cancer” resume unchanged? Screening will no doubt begin again, hopefully improved by data from the coronavirus natural experiment. But I wonder whether we will tolerate the same kinds of public health messages – and whether we should – having now experienced an infectious disease outbreak where our actions as individuals really do have an impact on the health of others.

After feeling helpless, besieged, and even guilt-ridden during the pandemic, I think many people would appreciate regaining a sense of control over other aspects of their health. Cancer screening can save lives, but it’s a choice we should make for ourselves based on an understanding of the trade-offs and our own preferences. When screening restarts, I hope its paternalistic dogma can be replaced by nuanced, empowering tactics more appropriate for peacetime.

My pathology lab once faced a daily flood of colon polyps, pap smears, and prostate biopsies. Suddenly, our work has dried up. The coronavirus pandemic has cleared out operating rooms and clinics across the country. Endoscopy and radiology suites have gone dark.

Pathology is largely driven by mass screening programs, and the machinery of screening has grinded to a halt during the COVID-19 pandemic. The American Cancer Society currently recommends that “no one should go to a health care facility for routine cancer screening at this time.”

But malignancies are still growing and spreading even though a great deal of medical care is on hold. The most urgent cancer care is still taking place; the risks of delaying treatment for patients with advanced or symptomatic cancer are obvious—these tumors can cause severe pain and life-threatening complications.

But that leaves us with a more complex and uncomfortable question: Will the pause in screening ultimately leave patients with tiny, asymptomatic cancers or precursor lesions worse off? What will a delay mean for those with ductal carcinoma in situ or small breast cancers? What’s the long-term effect of all those dysplastic nevi and early melanoma left unexcised by dermatologists? Perhaps more troubling, what about the spreading kidney cancer that may have turned up as an incidental finding on a CT scan?
 

COVID-19: A natural experiment

For many years, we’ve been dealing with the other side of the screening question: overdiagnosing and treating cancers that would probably never harm the patient. Overdiagnosis has been on a decades-long rise due to organized screening like PSA testing and mammography, as well as through ad hoc detection from heavier use of medical imaging. All of these have been disrupted by the pandemic.

Because the correlation between medical interventions and cancer overdiagnosis is clear, we can safely assume that overdiagnosis will decline during the pandemic. But what will be the net effect? Early detection of cancer undoubtedly saves some lives, but how many and at what cost has been a seemingly intractable debate.

Until now.

The coronavirus outbreak will be a natural experiment like no other. Economists and epidemiologists love to study “natural experiments” – systemic shocks that shed light on a complex phenomenon.

The unexpected nationwide delay in screening will undoubtedly inform the debate on overdiagnosis. For one, we can learn whether less intensive screening leads to more advanced cancers. Because screening will probably return to normal at different times across the country, we can almost simulate a randomized trial. Will this transformative data be a silver lining to this awful time?
 

The pressure to ‘fight’

The pandemic has also raised a question about cancer screening that goes beyond data: Why has the loud epidemic of coronavirus so thoroughly trumped cancer’s silent one? To me, the necessary urgency of our coronavirus response stands in stark contrast to the overly aggressive public health messaging used for cancer screening.

The tools used to fight the coronavirus epidemic have been forceful. We’re all diligently washing our hands and staying inside. We’re making sacrifices in our jobs and personal lives to stop the virus’ spread.

Ruxolitinib produced significantly better efficacy outcomes in patients with glucocorticoid-refractory acute graft-versus-host disease (GVHD), compared with investigator’s choice of control therapy, in the phase 3 REACH2 trial.

However, there was a higher incidence of thrombocytopenia with ruxolitinib than with control treatment, according to a report by Robert Zeiser, MD, of University of Freiburg (Germany) and colleagues on behalf of the REACH2 research group. The report was published in the New England Journal of Medicine.

The REACH2 trial (NCT02913261) is a randomized, open-label, phase 3 trial comparing the efficacy and safety of oral ruxolitinib (10 mg twice daily) with investigator’s choice of therapy for control treatment using a list of nine commonly used options.

Patients were 12 years of age or older with glucocorticoid-refractory acute GVHD after allogeneic stem cell transplant. A total of 154 patients were assigned to the ruxolitinib group, and 155 patients were in the control group.

Most patients – 152 in the ruxolitinib group and 150 in the control group – received at least one dose of trial treatment.

Treatment discontinuation occurred in 72% (111/154) of patients in the ruxolitinib group and in 85% (132/155) of those in the control group. The most common reason for discontinuation was lack of efficacy (in 21% and 44%, respectively).
 

Outcomes

The overall response at day 28 (the primary endpoint) was significantly higher in the ruxolitinib group than in the control group (62% vs. 39%; odds ratio, 2.64; P < .001). The durable overall response at day 56 was also significantly higher in the ruxolitinib group than in the control group (40% vs. 22%; OR, 2.38; P < .001).

The estimated cumulative incidence of loss of response at 6 months was 10% in the ruxolitinib group compared with 39% in the control group.

The median failure-free survival was considerably longer with ruxolitinib than with control treatment (5.0 months vs. 1.0 month; hazard ratio for relapse or progression of hematologic disease, non–relapse-related death, or the use of new systemic therapy for acute GVHD, 0.46).

The median overall survival was 11.1 months in the ruxolitinib group and 6.5 months in the control group (HR, 0.83).

Overall, 72 patients (47%) in the ruxolitinib group and 77 (51%) in the control group died by the data cutoff date. Most deaths were attributed to acute GVHD (22% in the ruxolitinib group and 25% in the control group).

The most common adverse events at day 28 (in the ruxolitinib and control arms, respectively) were thrombocytopenia (33% and 18%), anemia (30% and 28%), and cytomegalovirus infection (26% and 21%).
 

Praise for ‘successful’ randomized trial in GVHD

“The authors are to be congratulated for completing this successful randomized trial, which showed convincingly that ruxolitinib was more effective than the investigator’s choice of therapy ... in patients in whom glucocorticoid therapy had failed,” wrote Nelson Chao, MD, of Duke University in Durham, N.C., in his invited editorial.

He went on to speculate on the possible mechanism for ruxolitinib in these patients, discussing the possible role of the STAT3 and STAT1 signaling pathways.

Dr. Chao also found it “interesting that the incidence of infectious complications or relapse was apparently not greater with ruxolitinib than with control therapy,” but he noted that the total follow-up time was short.

“As with all good research, these observations raise important questions and set the stage for further work in this area,” he concluded.

The REACH2 trial was funded by Novartis. The study authors disclosed relationships with a variety of pharmaceutical companies, including Novartis. Dr. Chao reported having no relevant disclosures.

In a webinar designed to guide physicians in the care of hematology patients during the COVID-19 pandemic, three world experts on thalassemia and sickle cell disease (SCD) provided on-the-ground information from physicians who were dealing with the height of the crisis in their countries.

The webinar was organized by the European Hematology Association (EHA) and the Thalassemia International Federation (TIF).

Moderator Francesco Cerisoli, MD, head of research and mentoring at EHA, led the discussion with three guest speakers: Maria-Domenica Cappellini, MD, PhD, professor of hematology at the University of Milan; Androulla Eleftheriou, MD, executive director of TIF in Cyprus; and Raffaella Colombatti , MD, of the University of Padova in Italy, coordinator of the Red Cell Reserve Working Group of the Italian Association of Pediatric Hematology and Oncology.
 

Italian experience with thalassemia and COVID-19

Dr. Cappellini discussed the Italian experience with 11 thalassemia patients followed by a network survey who developed COVID-19 in the northern part of Italy, where the pandemic has been most widespread.

There are no published data focusing specifically on SARS-CoV-2 infection in patients with thalassemic syndromes, but patients with preexisting comorbidities are likely to be more severely affected by SARS-CoV-2, according to Dr. Cappellini.

Of particular concern is the fact that patients with thalassemia, especially older ones, are frequently splenectomized, which renders them more vulnerable to bacterial infections and can trigger life-threatening sepsis. However, splenectomy is not known to increase the risk of viral infection or severe viral illness. Of additional concern is the fact that many thalassemia patients need routine and frequent transfusions.

Overall, the 11 thalassemia patients who developed COVID-19 experienced only mild to moderate symptoms. This is despite the fact that 72% of the patients were splenectomized, which did not appear to affect the clinical course, and all of the patients had thalassemia-related comorbidities.

Around half of the patients were hospitalized, but none of them required transfer to the ICU. One patient who was treated with chemotherapy for diffuse large B-cell lymphoma in 2019 but is now in remission required more intense ventilation support with the use of continuous positive airway pressure.

Only three patients received specific treatment for COVID-19: one with hydroxychloroquine (HCQ) alone, one with HCQ plus anakinra, and one with HCQ plus ritonavir/darunavir.

Overall, “the number of infected thalassemia patients was lower than expected, likely due to earlier and more vigilant self-isolation compared to the general population,” Dr. Cappellini said. She pointed out that the first early response in February by thalassemia physicians was to warn their patients via email and phone calls about the need for self-isolation and precautions against the pandemic.

Physicians “rapidly reorganized activities, postponing nonessential ones” and managed to provide patients “a safe track at the hospital to receive their life-saving treatment in COVID-19–free areas with health care personnel wearing protective equipment” and assessment of all entering patients for COVID-19 infection, Dr. Cappellini said.
 

Results in additional thalassemia patients and SCD patients

Dr. Eleftheriou described 51 cases of thalassemia patients with SARS-CoV-2 infection reported to TIF as of April 16. Patients were from Cyprus, Italy, the United Kingdom, France, Turkey, Iran, Pakistan, and Indonesia.

Of the 51 patients, 46 presented with mild to moderate symptoms. Five patients had severe respiratory symptoms and required hospitalization, two were hospitalized and discharged, and three died between day 5 and day 15 post hospitalization.

Dr. Colombatti followed with a brief presentation of the intersection of COVID-19 with SCD patients. She presented anecdotal data involving 32 SCD patients who exhibited COVID-19 symptoms. Dr. Colombatti obtained the data via personal communication with Pablo Bartolucci, of Hôpitaux Universitaires Henri Mondor in Créteil, France.

All 32 SCD patients were screened and treated for COVID-19, and 17 of them continued treatment for 10 days. In all, 22 patients were hospitalized, 11 were transferred to the ICU, and 1 died.
 

Ensuring adequate blood supply

Dr. Eleftheriou also discussed the TIF response to the COVID-19 pandemic, which focused on the adequacy of blood supplies for these patients who so often need transfusions.

Dr. Eleftheriou stated that a shortage of blood was reported in 75% of the 62 member countries of the TIF, with 58% reporting severe shortages and 35% reporting moderate to severe shortages.

The shortages resulted in many countries returning to older family/friends donation practices, rare use of whole blood transfusions, and the use of older blood transfusions (older than 28 days).

In addition, physicians have modified their transfusion strategy. They have reduced the amount of blood given to thalassemia patients from two units to one unit during any transfusion, while making arrangements for more frequent transfusions; for example, one transfusion per week but with precautions made to “limit the time spent in the clinic and to control blood supplies while safeguarding that all [thalassemia] patients will be able to get their transfusion,” Dr. Eleftheriou said.

The information in the webinar was provided with the caveat that “no general evidence-based guidance can be derived from this discussion.” There were no other disclosures given.

Overall, the 11 thalassemia patients who developed COVID-19 experienced only mild to moderate symptoms. This is despite the fact that 72% of the patients were splenectomized, which did not appear to affect the clinical course, and all of the patients had thalassemia-related comorbidities.

Around half of the patients were hospitalized, but none of them required transfer to the ICU. One patient who was treated with chemotherapy for diffuse large B-cell lymphoma in 2019 but is now in remission required more intense ventilation support with the use of continuous positive airway pressure.

Only three patients received specific treatment for COVID-19: one with hydroxychloroquine (HCQ) alone, one with HCQ plus anakinra, and one with HCQ plus ritonavir/darunavir.

Overall, “the number of infected thalassemia patients was lower than expected, likely due to earlier and more vigilant self-isolation compared to the general population,” Dr. Cappellini said. She pointed out that the first early response in February by thalassemia physicians was to warn their patients via email and phone calls about the need for self-isolation and precautions against the pandemic.

Physicians “rapidly reorganized activities, postponing nonessential ones” and managed to provide patients “a safe track at the hospital to receive their life-saving treatment in COVID-19–free areas with health care personnel wearing protective equipment” and assessment of all entering patients for COVID-19 infection, Dr. Cappellini said.
 

Results in additional thalassemia patients and SCD patients

Dr. Eleftheriou described 51 cases of thalassemia patients with SARS-CoV-2 infection reported to TIF as of April 16. Patients were from Cyprus, Italy, the United Kingdom, France, Turkey, Iran, Pakistan, and Indonesia.

Of the 51 patients, 46 presented with mild to moderate symptoms. Five patients had severe respiratory symptoms and required hospitalization, two were hospitalized and discharged, and three died between day 5 and day 15 post hospitalization.

Dr. Colombatti followed with a brief presentation of the intersection of COVID-19 with SCD patients. She presented anecdotal data involving 32 SCD patients who exhibited COVID-19 symptoms. Dr. Colombatti obtained the data via personal communication with Pablo Bartolucci, of Hôpitaux Universitaires Henri Mondor in Créteil, France.

All 32 SCD patients were screened and treated for COVID-19, and 17 of them continued treatment for 10 days. In all, 22 patients were hospitalized, 11 were transferred to the ICU, and 1 died.
 

Ensuring adequate blood supply

Dr. Eleftheriou also discussed the TIF response to the COVID-19 pandemic, which focused on the adequacy of blood supplies for these patients who so often need transfusions.

Dr. Eleftheriou stated that a shortage of blood was reported in 75% of the 62 member countries of the TIF, with 58% reporting severe shortages and 35% reporting moderate to severe shortages.

The shortages resulted in many countries returning to older family/friends donation practices, rare use of whole blood transfusions, and the use of older blood transfusions (older than 28 days).

In addition, physicians have modified their transfusion strategy. They have reduced the amount of blood given to thalassemia patients from two units to one unit during any transfusion, while making arrangements for more frequent transfusions; for example, one transfusion per week but with precautions made to “limit the time spent in the clinic and to control blood supplies while safeguarding that all [thalassemia] patients will be able to get their transfusion,” Dr. Eleftheriou said.

The information in the webinar was provided with the caveat that “no general evidence-based guidance can be derived from this discussion.” There were no other disclosures given.

As an Episcopal priest, Father Robert Pace of Fort Worth, TX, is used to putting others first and reaching out to help. So when the pulmonologist who helped him through his ordeal with COVID-19 asked if he would like to donate blood to help other patients, he did not hesitate.

“I said, ‘Absolutely,’” Pace, 53, recalls. He says the idea was ‘very appealing.’ ” During his ordeal with COVID-19 in March, he had spent 3 days in the hospital, isolated and on IV fluids and oxygen. He was short of breath, with a heartbeat more rapid than usual.

Now, fully recovered, his blood was a precious commodity, antibody-rich and potentially life-saving.

As researchers scramble to test drugs to fight COVID-19, others are turning to an age-old treatment. They’re collecting the blood of survivors and giving it to patients in the throes of a severe infection, a treatment known as convalescent plasma therapy.

Doctors say the treatment will probably serve as a bridge until other drugs and a vaccine become available.

Although the FDA considers the treatment investigational, in late March, it eased access to it. Patients can get it as part of a clinical trial or through an expanded access program overseen by hospitals or universities. A doctor can also request permission to use the treatment for a single patient.

“It is considered an emergent, compassionate need,” says John Burk, MD, a pulmonologist at Texas Health Harris Methodist Hospital, Fort Worth, who treated Pace. “It is a way to bring it to the bedside.” And the approval can happen quickly. Burk says he got one from the FDA just 20 minutes after requesting it for a severely ill patient.
 

How it works

The premise of how it works is “quite straightforward,” says Michael Joyner, MD, a professor of anesthesiology at the Mayo Clinic, Rochester, MN. “When someone is recovered and no longer symptomatic, you can harvest those antibodies from their blood and give them to someone else, and hopefully alter the course of their disease.” Joyner is the principal investigator for the FDA’s national Expanded Access to Convalescent Plasma for the Treatment of Patients with COVID-19, with 1,000 sites already signed on.

Convalescent therapy has been used to fight many other viruses, including Ebola, severe acute respiratory syndrome (SARS), the “bird” flu, H1N1 flu, and during the 1918 flu pandemic. Joyner says the strongest evidence for it comes from the 1950s, when it was used to treat a rodent-borne illness called Argentine hemorrhagic fever. Using convalescent plasma therapy for this infection reduced the death rate from nearly 43% before the treatment became common in the late 1950s to about 3% after it was widely used, one report found.

Data about convalescent therapy specifically for COVID-19 is limited. Chinese researchers reported on five critically ill patients, all on mechanical ventilation, treated with convalescent plasma after they had received antiviral and anti-inflammatory medicines. Three could leave the hospital after 51-55 days, and two were in stable condition in the hospital 37 days after the transfusion.

In another study of 10 severely ill patients, symptoms went away or improved in all 10 within 1 to 3 days after the transfusion. Two of the three on ventilators were weaned off and put on oxygen instead. None died.

Chinese researchers also reported three cases of patients with COVID-19 given the convalescent therapy who had a satisfactory recovery.

Researchers who reviewed the track record of convalescent therapy for other conditions recently concluded that the treatment doesn’t appear to cause severe side effects and it should be studied for COVID-19.

Although information on side effects specific to this treatment is evolving, Joyner says they are “very, very low.”

According to the FDA, allergic reactions can occur with plasma therapies. Because the treatment for COVID-19 is new, it is not known if patients might have other types of reactions.
 

Who can donate?

Blood bank officials and researchers running the convalescent plasma programs say the desire to help is widespread, and they’ve been deluged with offers to donate. But requirements are strict.

Donors must have evidence of COVID-19 infection, documented in a variety of ways, such as a diagnostic test by nasal swab or a blood test showing antibodies. And they must be symptom-free for 14 days, with test results, or 28 days without.

The treatment involves collecting plasma, not whole blood. Plasma, the liquid part of the blood, helps with clotting and supports immunity. During the collection, a donor’s blood is put through a machine that collects the plasma only and sends the red blood cells and platelets back to the donor.
 

Clinical trials

Requirements may be more stringent for donors joining a formal clinical trial rather than an expanded access program. For instance, potential donors in a randomized clinical trial underway at Stony Brook University must have higher antibody levels than required by the FDA, says study leader Elliott Bennett-Guerrero, MD, medical director of perioperative quality and patient safety and professor at the Renaissance School of Medicine.

He hopes to enroll up to 500 patients from the Long Island, NY, area. While clinical trials typically have a 50-50 split, with half of subjects getting a treatment and half a placebo, Bennett-Guerrero’s study will give 80% of patients the convalescent plasma and 20% standard plasma.

Julia Sabia Motley, 57, of Merrick, NY, is hoping to become a donor for the Stony Brook study. She and her husband, Sean Motley, 59, tested positive in late March. She has to pass one more test to join the trial. Her husband is also planning to try to donate. “I can finally do something,” Sabia Motley says. Her son is in the MD-PhD program at Stony Brook and told her about the study.
 

Many questions remain

The treatment for COVID-19 is in its infancy. Burk has given the convalescent plasma to two patients. One is now recovering at home, and the other is on a ventilator but improving, he says.

About 200 nationwide have received the therapy, Joyner says. He expects blood supplies to increase as more people are eligible to donate.

Questions remain about how effective the convalescent therapy will be. While experts know that the COVID-19 antibodies “can be helpful in fighting the virus, we don’t know how long the antibodies in the plasma would stay in place,” Bennett-Guerrero says.

Nor do doctors know who the therapy might work best for, beyond people with a severe or life-threatening illness. When it’s been used for other infections, it’s generally given in early stages once someone has symptoms, Joyner says.

Joyner says he sees the treatment as a stopgap ‘’until concentrated antibodies are available.” Several drug companies are working to retrieve antibodies from donors and make concentrated antibody drugs.

“Typically we would think convalescent plasma might be a helpful bridge until therapies that are safe and effective and can be mass-produced are available, such as a vaccine or a drug,” Bennett-Guerrero says.

Even so, he says that he doesn’t think he will have a problem attracting donors, and that he will have repeat donors eager to help.
 

More information for potential donors

Blood banks, the American Red Cross, and others involved in convalescent plasma therapy have posted information online for potential donors. People who don’t meet the qualifications for COVID-19 plasma donations are welcomed as regular blood donors if they meet those criteria

According to the FDA, a donation could potentially help save the lives of up to four COVID-19 patients.

Father Pace is already planning another visit to the blood bank. To pass the time last time, he says, he prayed for the person who would eventually get his blood.
