Improving hand hygiene, optimizing antibiotic order sets, and removing catheters sooner were among the interventions associated with a decreased risk of infections after hysterectomy, according to research presented at the virtual annual scientific meeting of the Society of Gynecologic Surgeons.

“Implementation of bundled interventions and an institutional focus on reducing infection can successfully reduce the burden of posthysterectomy infectious morbidity,” said study author Shitanshu Uppal, MBBS, an ob.gyn. specializing in gynecologic oncology at the University of Michigan in Ann Arbor.

To assess the impact of quality improvement efforts on infectious morbidity after hysterectomy, Dr. Uppal and colleagues analyzed data from 1,867 hysterectomies performed between Oct. 8, 2015, and Oct. 7, 2018. Patients were at least 18 years old, younger than 90 years old, and underwent hysterectomy via any route at the University of Michigan Medical Center Hospital.

Interventions to reduce infections included the use of cefazolin as a preferred antibiotic, the addition of metronidazole to first-generation cephalosporins for antibiotic prophylaxis, subcuticular closure of open incisions, and earlier removal of Foley catheters. In addition, the institution evaluated and shared information about doctors’ hand hygiene, implemented enhanced recovery after surgery (ERAS) protocols, and held periodic meetings with doctors to discuss efforts to reduce infections. Most interventions were implemented by November 2017.

The primary outcome was overall infection rate in the 30 days after surgery for each of the 3 years included the study. Infections included superficial surgical site infections, deep infections, Clostridium difficile infections, and urinary tract infections, among others.

Patients’ baseline clinical characteristics did not differ during the 3 years studied. Length of stay decreased, which may be attributed to increased use of ERAS protocols and institution of same-day discharge in laparoscopic cases, Dr. Uppal said. The rate of malignancy on final pathology decreased from 29% in year 1 to 23% in year 3. The rate of laparoscopic surgery increased from 55% to 64%.

Infectious morbidity rates decreased from 7% in year 1 (47 infections per 644 cases) to 4% in year 3 (22 infections per 616 cases).

“We saw a reduction in infection rate in all categories,” said Dr. Uppal. “However, the reduction in urinary tract infection as well as superficial surgical site infection was most pronounced.”

After adjustment for the route of surgery, body mass index, age, malignancy on final pathology, modality of surgery, and comorbidities, performance of hysterectomy in year 3 was independently predictive of lower rates of infectious morbidity by 56%.

In addition, the standardized incidence ratio for surgical site infection as reported by the Centers for Medicare & Medicaid Services decreased. In December 2016, Michigan Medicine’s ratio was 1.057. At the end of 2018, the projected ratio was 0.243.

The interventions started on different dates, and “we are unable to conclude, from all the implemented interventions, which one worked,” Dr. Uppal noted.

“I hope the elements from this quality improvement initiative will become the standard of care in order to benefit our patients,” said Amy Park, MD, section head of female pelvic medicine and reconstructive surgery at Cleveland Clinic.

An erythematous rash was the most common cutaneous manifestation in patients with COVID-19, followed by chilblain-like lesions and urticaria-like lesions in a systematic review of mostly European studies.

Qing Zhao, MD, Xiaokai Fang, MD, and their colleagues at the Shandong Provincial Hospital for Skin Diseases & Shandong Provincial Institute of Dermatology and Venereology, in Jinan, China, reported the results of a literature review of 44 articles published through May 2020 that included 507 patients with cutaneous manifestations of COVID-19. The review was published in the Journal of The European Academy of Dermatology and Venereology.

Nearly all of the patients (96%) were from Europe, and more than half were women (60%), with an average age of 49 years. Most patients had multiple skin symptoms, with the most common being erythema (44%), chilblain-like lesions (20%), urticaria-like lesions (16%), vesicular manifestations (13%), livedo/necrosis (6%), and petechiae (almost 2%). The authors described erythema as being present in specific sites, such as the trunk, extremities, flexural regions, face, and mucous membranes. Slightly less than half of all patients had significant pruritus.

Data on systemic COVID-19 symptoms were available for 431 patients and included fever in about two-thirds of patients and cough in almost 70%, with dyspnea in almost half of patients. Almost 60% had fatigue, and almost 60% had asthenia. Information about the onset of skin symptoms was available in 88 patients; of these patients, lesions were seen an average of almost 10 days after systemic symptoms appeared and, in almost 15%, were the first symptoms noted.

Histopathologic exams were done for only 23 patients and, in all cases, showed “inflammatory features without specific pathological changes, such as lymphocyte infiltration.” In one study, reverse transcription polymerase chain reaction testing of skin biopsy specimens tested negative for SARS-CoV-2.

Expression of ACE2, the receptor of SARS-CoV-2, in the skin was evaluated in six of the studies. “Higher ACE2 expression was identified in keratinocytes, mainly in differentiating keratinocytes and basal cells compared to the other cells of skin tissues,” the authors wrote. These results were confirmed with immunohistochemistry, which, they said, found “ACE2-positive keratinocytes in the stratum basal, the stratum spinosum, and the stratum granulosum of epiderma.” They added that this provides evidence “for percutaneous infection or the entry of virus into patients through skin tissues,” but cautioned that more research is needed.

The authors acknowledged that there are still many unanswered questions about COVID-19, and that more clinical data and research are needed, to improve the understanding of the cutaneous manifestations associated with COVID-19.

Pathogenesis of different cutaneous manifestations may be different, Dr. Femia said. For example, urticaria and morbilliform eruption were described by the authors of the review as more benign eruptions, but pathogenesis may differ from that of so-called COVID toes and from the pathogenesis of purpura and ulcerations seen in patients with more severe disease, she noted. It is plausible, she added, that purpura and ulcerations may be a “direct invasion of SARS-CoV-2 into endothelial cells,” which creates secondary processes “that ultimately destroy the skin.”

Urticaria and morbilliform eruptions, on the other hand, “are more simply that the immune system is recognizing COVID, and in doing so, is also recognizing some antigens in the skin and creating a hypersensitive response to the skin” and has “nothing to do with the SARS-CoV-2 virus actually being in that location,” she said.

It is important to differentiate between patients who have skin manifestations attributed to COVID-19 and those with manifestations independent of COVID-19, which is difficult, Dr. Femia noted. A patient with COVID-19 and a cutaneous manifestation may be having a reaction to a medication. “It’s important to have a critical eye and to remember that, when we see these manifestations, we should always be investigating whether there was an alternative cause so that we can better learn what exactly we should be attributing to this infection,” she said

Adam Friedman, MD, professor and interim chair of dermatology at George Washington University, Washington, said the authors of the review had presented interesting work, but made some “assumptions that need to be proven.” Dr. Friedman also was not involved in the research, but agreed in an interview with the assessment that it is unlikely SARS-CoV-2 would penetrate the skin. While some viruses – such as the poxvirus that causes molluscum contagiosum and the herpes simplex virus – invade keratinocytes specifically, there is a particular clinical phenotype that results that is associated with changes in the epidermis. However, “the skin manifestations of COVID-19 do not fit with direct skin invasion, [but] rather the immune response to systemic disease,” he said.

“[I]n terms of systemic invasion through the skin, it is possible, but this study certainly doesn’t show that. The presence/expression of ACE2 in the epidermis doesn’t translate to route of infection,” Dr. Friedman said..

The study received financial support from Shandong First Medical University, the Innovation Project of Shandong Academy of Medical Sciences and the Shandong Province Taishan Scholar Project. The authors report no relevant financial disclosures. Dr. Femia and Dr. Friedman had no relevant financial disclosures.

When the pandemic was just emerging from its infancy and we were just beginning to think about social distancing, I was sitting around enjoying an adult beverage and some gluten free (not my choice) snacks with some friends. A retired nurse who had just celebrated her 80th birthday said, “I can’t wait until they’ve developed a vaccine.” A former electrical engineer sitting just short of 2 meters to her left responded, “Don’t save me a place near the front of the line for something that is being developed in a program called Warp Speed.”

How do you feel about the potential SARS-CoV-2 vaccine? Are you going to roll up your sleeve as soon as the vaccine becomes available in your community? What are you going to suggest to your patients, your children? I suspect many of you will answer, “It depends.” What factors will you be considering when you try to decide between what is likely to be several competing SARS-CoV-2 vaccines?

Will it make any difference to you which biochemical-immune-bending strategy is being used to make the vaccine? All of them will probably be the result of a clever sounding but novel technique, all of them with a track record that is measured in months and not years. Will you be swayed by how large the trials were? Or how long the follow-up lasted? How effective must the vaccine be to convince you that it is worth receiving or recommending? Do you have the tools and experience to make a decision like that? I know I don’t. And should you and I even be put in a position to make that decision?

In the past, you and I may have relied on the Centers for Disease Control and Prevention for advice. But given the somewhat murky and stormy relationship between the CDC and the president, the vaccine recommendation may be issued by the White House and not the CDC.

For those of us who were practicing medicine during the Swine Flu fiasco of 1976, the pace and the politics surrounding the development of a SARS-CoV-2 vaccine has a discomforting déjà vu quality about it. The fact that like this year 1976 was an election year that infused the development process with a sense of urgency above and beyond any of the concerns about the pandemic that never happened. Although causality was never proven, there was a surge in Guillain-Barré syndrome cases that had been linked temporally to the vaccine.

Of course, our pandemic is real, and it would be imprudent to wait a year or more to watch for long-term vaccine sequelae. However, I am more than a little concerned that fast tracking the development process may result in unfortunate consequences in the short term that could have been avoided with a more measured approach to trialing the vaccines.

The sad reality is that as a nation we tend to be impatient. We are drawn to quick fixes that come in a vial or a capsule. We are learning that simple measures like mask wearing and social distancing can make a difference in slowing the spread of the virus. It would be tragic to rush a vaccine into production that at best turns out to simply be an expensive alternative to the measures that we know work or at worst injures more of us than it saves.

Of course, our pandemic is real, and it would be imprudent to wait a year or more to watch for long-term vaccine sequelae. However, I am more than a little concerned that fast tracking the development process may result in unfortunate consequences in the short term that could have been avoided with a more measured approach to trialing the vaccines.

The sad reality is that as a nation we tend to be impatient. We are drawn to quick fixes that come in a vial or a capsule. We are learning that simple measures like mask wearing and social distancing can make a difference in slowing the spread of the virus. It would be tragic to rush a vaccine into production that at best turns out to simply be an expensive alternative to the measures that we know work or at worst injures more of us than it saves.

It turns out that a pandemic, at least this COVID-19 version, can be a challenge for folks like me who are seldom at a loss for words. The pandemic has so overwhelmed every corner of our lives that it is hard to think of another topic on which to pontificate and still not tromp on someone’s political toes. One can always write about the pandemic itself, and I’ve tried that, but as the curtain is gradually being pulled back on this crafty little germ one runs the risk of making an observation today that will be disproved in a week or 2. However, I can’t suppress my urge to write, and so I have decided to share a few brief random observations. Of course they are related to the pandemic. And of course I realize that there is a better than fifty percent chance that they will be proved wrong by the time you read my next Letters from Maine.

Two of the many mysteries about SARS-CoV-2 involve young children who as a group appear to be less easily infected than adults and even when infected seem to be less likely to spread the disease to other people, particularly adults. One explanation posited by some researchers in France is that young children are less likely to have symptoms such as cough and are less powerful speakers and so might be less likely to spew out a significant number of infected aerosolized droplets (“How to Reopen Schools: What Science and Other Countries Teach Us.” By Pam Belluck, Apoorva Mandavill, and Benedict Carey. New York Times, July 11, 2020). While there are probably several factors to explain this observation, one may be that young children are short, seldom taller than an adult waistline. I suspect the majority of aerosols they emit fall and inactivate harmlessly to the floor several feet below an adult’s nose and mouth. Regardless of the explanation, it appears to be good news for the opening of schools, at least for the early grades.

Forget the deep cleaning

There has been a glut of news stories about reopening schools, and many of these stories are accompanied by images of school custodians with buckets, mops, spray bottles, and sponges scouring desks and walls. The most recent image in our local newspaper was of someone scrubbing the underside of a desk. I know it’s taking the World Health Organization an unconscionable period of time to acknowledge that SARS-CoV-2 is airborne, but the rest of us should have gotten the message long ago and been directing our attention to air handling and ventilation. The urge to scrub and deep clean is a hard habit to break, but this nasty bug is not like influenza or a flesh eating bacteria in which deep cleaning might help. A better image to attach to a story on school reopening would be one of a custodian with a screwdriver struggling to pry open a classroom window that had been painted shut a decade ago.

Managing the inevitable

Middlebury College in Vermont and Bowdoin College here in Brunswick, Maine, are similar in many respects because they are small and situated in relatively isolated small New England towns with good track records for pandemic management. Middlebury has elected to invite all its 2,750 students back to campus, whereas Bowdoin has decided to allow only incoming first years and transfer students (for a total of about 600) to return. Both schools will institute similar testing and social distancing protocols and restrict students from access to their respective towns (“A Tale of 2 Colleges.” By Bill Burger. Inside Higher Ed, June 29,2020). It will be an interesting experiment. I’m voting for Middlebury and not because my son and daughter-in-law are alums, but because I think Middlebury seems to have acknowledged that no matter how diligent one is in creating a SARS-CoV-2–free environment at the outset, these are college kids and there will be some cases on both campuses. It is on how those inevitable realities are managed and contained that an institution should be judged.

Patience

Unfortunately, the pandemic has exposed some of our weaknesses as a nation. We always have been a restless and impatient population eager to get moving and it has driven us to greatness. Hopefully, patience will be a lesson that we will learn, along with many others.

Biomedical science is ever changing, and what may be believed in one era – for instance, bloodletting can cure disease or lobotomies can treat psychiatric disorders – may not be accepted in the next. However, one medical advance stands out in terms of maintaining and sustaining our health: vaccines. The data comparing morbidity and mortality before and after widespread vaccination are staggering. Before the smallpox vaccine, nearly 49,000 people were infected and more than 1,500 died annually from smallpox; by 1977, the vaccine eradicated the disease in the United States.¹ Polio caused paralytic disease in more than 16,000 people per year in the United States, including, perhaps most famously, President Franklin Roosevelt. After development of the polio vaccine, cases and deaths dropped to zero.²

Despite the evidence indicating the effectiveness of vaccines to reduce disease and death, rates of vaccination in the United States remain low among adults, ranging from about 23% for pneumococcal disease to 45% for seasonal influenza.³ Childhood immunization in 2017 hovered around 70% for those receiving all the recommended vaccines.⁴ Clearly there is room for improvement.

A woman’s ob.gyn. may be the only medical professional she sees regularly, and her annual well visit may be the only time she receives information regarding her weight and blood pressure, or reviews her current medications. For women who are planning pregnancy, pregnant, or post partum, ob.gyn. consultations present unique opportunities to increase patient engagement in healthy behaviors, such as diet, exercise, and regular sleep, because women are highly motivated to do what is best for their babies.

Immunization during pregnancy not only reduces the mother’s risk of severe disease, which can lead to complications, defects, and fetal or perinatal death, but also has been shown to improve the neonate’s ability to fight infection and may reduce vertical transmission of certain diseases. In this era of COVID-19 where we have no vaccine but we have evidence that pregnant women may be at greater risk for severe disease,⁵ routine immunizations are vital to maternal and fetal health.

We have invited Laura E. Riley, MD, chair of obstetrics and gynecology at Weill Cornell Medicine, New York, to address the importance of vaccination and the role of the ob.gyn. in advocating for this life-saving preventive health measure. Dr. Riley disclosed she is an author for Up to Date and was a consultant to GlaxoSmithKline about a cytomegalovirus vaccine.

Maternal immunization remains a priority for ob.gyns. – an opportunity to provide protection against serious infectious diseases for both the mother and the baby. With influenza vaccination rates in pregnant women still hovering around 50% and the emerging public health problem of vaccine hesitancy, we must fully embrace our responsibility to recommend immunizations and to effectively communicate what is known about their efficacy and safety. Ideally, we should offer them as well.

One reason for the low rates of influenza vaccination – one of the two vaccinations routinely recommended for all pregnant women in the United States – is that pregnant women do not always know the importance of the vaccine. This is actionable: Data clearly show that the physician’s recommendation makes a difference and that a clinician’s offer to administer the vaccination has an even greater impact.

A 2017 Centers for Disease Control and Prevention analysis of data from Internet panel surveys¹ shows that women who reported receiving both a clinician recommendation and offer of vaccination had higher coverage during the 2015-2016 and 2016-2017 influenza seasons (63.7% and 70.5%) than did women who reported receiving a clinician recommendation but no offer (37.5% and 43.7%) and women who reported receiving no recommendation for vaccination (12.8% and 14.8%).

The analysis suggests there are consistently missed opportunities: Fewer than 70% (67.3%) of pregnant women in the 2016-2017 flu season reported receiving a clinician recommendation for and offer of vaccination. This is similar to the prior three flu seasons, according to the CDC.

This year, with the COVID-19 pandemic ensuing, the prevention of severe influenza illness – and other vaccine-preventable illnesses – takes on even greater importance. It is not known what the impact of two potentially devastating respiratory infections could be for pregnant individuals. Therefore, maximal protection against at least influenza will be critical.
 

Influenza and Tdap

Poor outcomes and disproportionately high death rates for pregnant women were observed in both the influenza pandemic of 1918-1919 and the 1957 “Asian flu” pandemic. Maternal immunization for influenza has been recommended in the United States since 2004 (part of the recommendation that everyone over the age of 6 months receive an annual flu vaccine), but it was the H1N1 influenza pandemic of 2009 that reinforced its value and led our field to more fully embrace influenza vaccination as a priority for prenatal care.

Surprisingly, most of the pregnant women who became severely ill from the H1N1 virus were young and healthy and did not have a coexisting condition known to increase risk, such as asthma or diabetes. In an analysis of California epidemiologic data, ² only one-third of 94 pregnant women who were hospitalized with 2009 H1N1 influenza had established risk factors for complications from influenza, compared with almost two-thirds of nonpregnant women of reproductive age.

Nationally, 75 deaths of pregnant women were confirmed as because of H1N1 and 34 were possibly related to H1N1, most of which (64.3%) occurred in the third trimester.³ Records of the 1957 pandemic similarly show that pregnant women in the second and third trimesters were particularly affected.

That healthy pregnant women became so ill during the H1N1 pandemic raised several flags. For one, it became clearer that pregnancy is its own significant risk factor for severe illness from the influenza virus. Physiological changes believed to make a pregnant woman more susceptible to becoming ill include decreased lung capacity, increased nasal congestion, reduced colloid oncotic pressure, and changes in the immune system. The morbidity and mortality from H1N1 influenza also increased our drive as a specialty to convince women that vaccination is an important strategy in each influenza season.

The flu vaccine can be administered at any point during pregnancy. There is no evidence that the safety profile is any different during one trimester than another.

Patients should be reassured that vaccines recommended in pregnancy have undergone rigorous testing and that the influenza vaccine has been given to millions of pregnant women over decades. They also should understand that contracting influenza has risks for the fetus; research has demonstrated that pregnant women who contract influenza are at greater risk of spontaneous abortion as well as preterm birth and low birth weight.⁴

In addition, the issue of flu vaccine efficacy needs to be properly teased apart. Women read every year that the vaccine is not effective, so we need to discuss with patients what efficacy means. Does the vaccine prevent illness altogether, or does it prevent severe illness? For the most part, whereas influenza vaccines often do not offer an exact match for the year’s circulating strains – and therefore may not prevent all illness – data show that the vaccine can prevent severe illness.⁵ That is a worthy outcome.

Also worthy is the impact of influenza vaccination on the newborn. That maternal immunization also protects the baby – it can reduce the risk for influenza in infants under 6 months of age – is underappreciated and should be part of patient counseling. There is clear evidence that maternal immunization boosts the concentration of maternal antibodies that can cross the placenta and that infants benefit from this passive antibody protection.⁶

The Tdap vaccine (tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis), the second vaccine routinely recommended during each pregnancy, is administered as early as possible during the third trimester precisely for this reason – to boost maternal immune response and maximize the passive transfer of antibodies to the newborn. The target is the prevention of pertussis and associated hospitalizations and death during the first 2 months of life in an era when sporadic and unpredictable outbreaks of the infection are occurring.

Data from the CDC of morbidity and mortality from pertussis in children (2001-2011) prior to routine maternal vaccination show that the highest rates of pediatric hospitalizations and deaths occurred in newborns. Research has demonstrated that the Tdap vaccine is highly effective in preventing infections and hospitalizations in newborns: Case-control and cohort studies in the United Kingdom^7,8 have shown vaccine effectiveness of 91%-93%, and similar research⁹ done in the U.S. has demonstrated effectiveness of 78%-85%.

The Tdap vaccine is recommended for pregnant women at 27-36 weeks of gestation – in each pregnancy. The reason for revaccination with each pregnancy is that antibody levels do not remain high for too long; at 8 months post immunization, research has shown, maternal antibody levels have begun to wane.

The vaccine also is recommended for all individuals who will be in close contact with infants younger than 12 months (for example, parents, grandparents, and child-care providers) and who have not previously received it. However, “cocooning” the newborn is effective only when the mother also is immunized – a point that ob.gyns. need to better explain to their patients so that they understand the purpose of this strategy.
 

Other vaccines in pregnancy and post partum

As described in the American College of Obstetricians and Gynecologists’ committee opinion on maternal immunization, ⁴ it is the responsibility of the ob.gyn. or obstetric care provider to routinely assess the immunization status of every pregnant patient and recommend additional vaccines for those patients who have conditions or social/behavioral practices that put them at higher risk of acquiring vaccine-preventable diseases.

Patients who have asthma or diabetes, who smoke, or who have never been vaccinated for the prevention of pneumococcal disease should receive the PPV23 pneumococcal vaccine, for instance. For pregnant women with immune deficiencies such as HIV, the PCV13 vaccine followed by PPV23 is recommended. There are approximately 500,000 cases of invasive pneumococcal disease in the United States each year, resulting in 40,000 deaths, and many multidrug-resistant strains of Streptococcus pneumoniae.

Hepatitis A and B vaccines – both recombinant vaccines with no safety concerns – also can be given during pregnancy and are officially recommended for women who have high-risk exposures. In the case of hepatitis A, high risk entails traveling to countries where the disease is endemic. High-risk behavior for hepatitis B includes sex work or being the household contact or sexual partner of a person positive for hepatitis B surface antigen.

Other travel-related vaccines, such as Japanese encephalitis, yellow fever, smallpox, and inactivated polio vaccine, can be considered in pregnancy, but decisions should be driven by more in-depth conversations about potential risks and benefits. Unlike for other vaccinations, there are limited data on the safety of travel-related immunizations in pregnancy. Sometimes, the question of whether travel is advisable in the middle of pregnancy – whether potential risks are worth taking – is a valid question to pose in conversations with patients.

Standard obstetric practice includes assessment of rubella susceptibility at the beginning of pregnancy. In some locations such as New York, measles susceptibility is also routinely evaluated. After delivery, seronegative women should be vaccinated with MMR (measles, mumps, and rubella) vaccine prior to discharge. In recent years, with the growing problem of vaccine refusal and an increasingly mobile and global society, we’re seeing sporadic outbreaks of measles and rubella – diseases that were once eradicated.

Measles in particular is highly contagious and requires a herd immunity threshold of 92%-94% to prevent sustained spread of the disease. Postpartum immunization has important maternal and pediatric implications for subsequent pregnancies, before which vaccination is often missed.

Both the MMR vaccine and the varicella vaccine (another vaccine that can be initiated post partum) are live vaccines and therefore contraindicated during pregnancy but should be administered post partum, including to people who are breastfeeding.

Other immunizations that hold some promise to protect either the mother or fetus/neonate or both are in various stages of development or testing. These include vaccines for cytomegalovirus, malaria, respiratory syncytial virus, and group B streptococcus.
 

A word about COVID-19

In mid-July there were more than 120 vaccine candidates for COVID-19 in various phases of study and a host of questions. Will a vaccine be efficacious? Will it prevent severe illness, or illness altogether? And will it be safe for pregnant women?

Vaccines work by manipulating the immune system, and it is important to appreciate the possibility that there may be unique pregnancy-related issues to consider with future COVID-19 vaccines – issues that could influence the effectiveness, safety, and timing of vaccination – and to understand that with any new immunization, there will likely be reluctance on the part of pregnant women who routinely prioritize fetal safety over their own health.

Pregnant women have been excluded from COVID-19 vaccine trials, but there may come a time when experts decide that a vaccine against COVID-19 is beneficial in pregnancy. Thus far, we know that the disease is clearly different from influenza. A growing knowledge of the impact of COVID-19 on the health of pregnant women, particularly the risk of developing severe illness, will be important for the future of COVID-19 immunization, as many women will not want to accept any potential risk of a vaccine unless they believe there is a significant benefit.

Maternal immunization remains a priority for ob.gyns. – an opportunity to provide protection against serious infectious diseases for both the mother and the baby. With influenza vaccination rates in pregnant women still hovering around 50% and the emerging public health problem of vaccine hesitancy, we must fully embrace our responsibility to recommend immunizations and to effectively communicate what is known about their efficacy and safety. Ideally, we should offer them as well.

One reason for the low rates of influenza vaccination – one of the two vaccinations routinely recommended for all pregnant women in the United States – is that pregnant women do not always know the importance of the vaccine. This is actionable: Data clearly show that the physician’s recommendation makes a difference and that a clinician’s offer to administer the vaccination has an even greater impact.

A 2017 Centers for Disease Control and Prevention analysis of data from Internet panel surveys¹ shows that women who reported receiving both a clinician recommendation and offer of vaccination had higher coverage during the 2015-2016 and 2016-2017 influenza seasons (63.7% and 70.5%) than did women who reported receiving a clinician recommendation but no offer (37.5% and 43.7%) and women who reported receiving no recommendation for vaccination (12.8% and 14.8%).

The analysis suggests there are consistently missed opportunities: Fewer than 70% (67.3%) of pregnant women in the 2016-2017 flu season reported receiving a clinician recommendation for and offer of vaccination. This is similar to the prior three flu seasons, according to the CDC.

This year, with the COVID-19 pandemic ensuing, the prevention of severe influenza illness – and other vaccine-preventable illnesses – takes on even greater importance. It is not known what the impact of two potentially devastating respiratory infections could be for pregnant individuals. Therefore, maximal protection against at least influenza will be critical.
 

Influenza and Tdap

Poor outcomes and disproportionately high death rates for pregnant women were observed in both the influenza pandemic of 1918-1919 and the 1957 “Asian flu” pandemic. Maternal immunization for influenza has been recommended in the United States since 2004 (part of the recommendation that everyone over the age of 6 months receive an annual flu vaccine), but it was the H1N1 influenza pandemic of 2009 that reinforced its value and led our field to more fully embrace influenza vaccination as a priority for prenatal care.

Surprisingly, most of the pregnant women who became severely ill from the H1N1 virus were young and healthy and did not have a coexisting condition known to increase risk, such as asthma or diabetes. In an analysis of California epidemiologic data, ² only one-third of 94 pregnant women who were hospitalized with 2009 H1N1 influenza had established risk factors for complications from influenza, compared with almost two-thirds of nonpregnant women of reproductive age.

Nationally, 75 deaths of pregnant women were confirmed as because of H1N1 and 34 were possibly related to H1N1, most of which (64.3%) occurred in the third trimester.³ Records of the 1957 pandemic similarly show that pregnant women in the second and third trimesters were particularly affected.

That healthy pregnant women became so ill during the H1N1 pandemic raised several flags. For one, it became clearer that pregnancy is its own significant risk factor for severe illness from the influenza virus. Physiological changes believed to make a pregnant woman more susceptible to becoming ill include decreased lung capacity, increased nasal congestion, reduced colloid oncotic pressure, and changes in the immune system. The morbidity and mortality from H1N1 influenza also increased our drive as a specialty to convince women that vaccination is an important strategy in each influenza season.

The flu vaccine can be administered at any point during pregnancy. There is no evidence that the safety profile is any different during one trimester than another.

Patients should be reassured that vaccines recommended in pregnancy have undergone rigorous testing and that the influenza vaccine has been given to millions of pregnant women over decades. They also should understand that contracting influenza has risks for the fetus; research has demonstrated that pregnant women who contract influenza are at greater risk of spontaneous abortion as well as preterm birth and low birth weight.⁴

In addition, the issue of flu vaccine efficacy needs to be properly teased apart. Women read every year that the vaccine is not effective, so we need to discuss with patients what efficacy means. Does the vaccine prevent illness altogether, or does it prevent severe illness? For the most part, whereas influenza vaccines often do not offer an exact match for the year’s circulating strains – and therefore may not prevent all illness – data show that the vaccine can prevent severe illness.⁵ That is a worthy outcome.

Also worthy is the impact of influenza vaccination on the newborn. That maternal immunization also protects the baby – it can reduce the risk for influenza in infants under 6 months of age – is underappreciated and should be part of patient counseling. There is clear evidence that maternal immunization boosts the concentration of maternal antibodies that can cross the placenta and that infants benefit from this passive antibody protection.⁶

The Tdap vaccine (tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis), the second vaccine routinely recommended during each pregnancy, is administered as early as possible during the third trimester precisely for this reason – to boost maternal immune response and maximize the passive transfer of antibodies to the newborn. The target is the prevention of pertussis and associated hospitalizations and death during the first 2 months of life in an era when sporadic and unpredictable outbreaks of the infection are occurring.

Data from the CDC of morbidity and mortality from pertussis in children (2001-2011) prior to routine maternal vaccination show that the highest rates of pediatric hospitalizations and deaths occurred in newborns. Research has demonstrated that the Tdap vaccine is highly effective in preventing infections and hospitalizations in newborns: Case-control and cohort studies in the United Kingdom^7,8 have shown vaccine effectiveness of 91%-93%, and similar research⁹ done in the U.S. has demonstrated effectiveness of 78%-85%.

The Tdap vaccine is recommended for pregnant women at 27-36 weeks of gestation – in each pregnancy. The reason for revaccination with each pregnancy is that antibody levels do not remain high for too long; at 8 months post immunization, research has shown, maternal antibody levels have begun to wane.

The vaccine also is recommended for all individuals who will be in close contact with infants younger than 12 months (for example, parents, grandparents, and child-care providers) and who have not previously received it. However, “cocooning” the newborn is effective only when the mother also is immunized – a point that ob.gyns. need to better explain to their patients so that they understand the purpose of this strategy.
 

Other vaccines in pregnancy and post partum

As described in the American College of Obstetricians and Gynecologists’ committee opinion on maternal immunization, ⁴ it is the responsibility of the ob.gyn. or obstetric care provider to routinely assess the immunization status of every pregnant patient and recommend additional vaccines for those patients who have conditions or social/behavioral practices that put them at higher risk of acquiring vaccine-preventable diseases.

Patients who have asthma or diabetes, who smoke, or who have never been vaccinated for the prevention of pneumococcal disease should receive the PPV23 pneumococcal vaccine, for instance. For pregnant women with immune deficiencies such as HIV, the PCV13 vaccine followed by PPV23 is recommended. There are approximately 500,000 cases of invasive pneumococcal disease in the United States each year, resulting in 40,000 deaths, and many multidrug-resistant strains of Streptococcus pneumoniae.

Hepatitis A and B vaccines – both recombinant vaccines with no safety concerns – also can be given during pregnancy and are officially recommended for women who have high-risk exposures. In the case of hepatitis A, high risk entails traveling to countries where the disease is endemic. High-risk behavior for hepatitis B includes sex work or being the household contact or sexual partner of a person positive for hepatitis B surface antigen.

Other travel-related vaccines, such as Japanese encephalitis, yellow fever, smallpox, and inactivated polio vaccine, can be considered in pregnancy, but decisions should be driven by more in-depth conversations about potential risks and benefits. Unlike for other vaccinations, there are limited data on the safety of travel-related immunizations in pregnancy. Sometimes, the question of whether travel is advisable in the middle of pregnancy – whether potential risks are worth taking – is a valid question to pose in conversations with patients.

Standard obstetric practice includes assessment of rubella susceptibility at the beginning of pregnancy. In some locations such as New York, measles susceptibility is also routinely evaluated. After delivery, seronegative women should be vaccinated with MMR (measles, mumps, and rubella) vaccine prior to discharge. In recent years, with the growing problem of vaccine refusal and an increasingly mobile and global society, we’re seeing sporadic outbreaks of measles and rubella – diseases that were once eradicated.

Measles in particular is highly contagious and requires a herd immunity threshold of 92%-94% to prevent sustained spread of the disease. Postpartum immunization has important maternal and pediatric implications for subsequent pregnancies, before which vaccination is often missed.

Both the MMR vaccine and the varicella vaccine (another vaccine that can be initiated post partum) are live vaccines and therefore contraindicated during pregnancy but should be administered post partum, including to people who are breastfeeding.

Other immunizations that hold some promise to protect either the mother or fetus/neonate or both are in various stages of development or testing. These include vaccines for cytomegalovirus, malaria, respiratory syncytial virus, and group B streptococcus.
 

A word about COVID-19

In mid-July there were more than 120 vaccine candidates for COVID-19 in various phases of study and a host of questions. Will a vaccine be efficacious? Will it prevent severe illness, or illness altogether? And will it be safe for pregnant women?

Vaccines work by manipulating the immune system, and it is important to appreciate the possibility that there may be unique pregnancy-related issues to consider with future COVID-19 vaccines – issues that could influence the effectiveness, safety, and timing of vaccination – and to understand that with any new immunization, there will likely be reluctance on the part of pregnant women who routinely prioritize fetal safety over their own health.

Pregnant women have been excluded from COVID-19 vaccine trials, but there may come a time when experts decide that a vaccine against COVID-19 is beneficial in pregnancy. Thus far, we know that the disease is clearly different from influenza. A growing knowledge of the impact of COVID-19 on the health of pregnant women, particularly the risk of developing severe illness, will be important for the future of COVID-19 immunization, as many women will not want to accept any potential risk of a vaccine unless they believe there is a significant benefit.

The American Society for Metabolic & Bariatric Surgery (ASMBS) has issued a statement declaring that obesity surgery is not elective and should be resumed as soon as it›s safe to do so during the COVID-19 pandemic.

The ASMBS statement, “Safer Through Surgery,” was published online in Surgery for Obesity and Related Diseases by the ASMBS executive committee.

It is a reaction to the fact that some U.S. states have placed metabolic and bariatric surgery in the same low-priority category as cosmetic surgery as examples of “elective” procedures that should be among the last to be restarted when pandemic restrictions are eased.

Rather, ASMBS argues, although obesity surgery must be postponed along with other nonemergency procedures when surges in the novel coronavirus make them unsafe, such operations should be resumed as soon as possible along with other medically necessary procedures.

“Metabolic and bariatric surgery is NOT elective. Metabolic and bariatric surgery is medically necessary and the best treatment for those with the life-threatening and life-limiting disease of severe obesity,” the statement says.

And obesity itself is a major risk factor for worse COVID-19 outcomes, ASMBS President Matt Hutter, MD, told Medscape Medical News, noting that individuals with obesity are “more likely to be in [intensive care units].”

“Mortality rates are higher, even in young patients. And [obesity] ... is associated with other comorbidities including diabetes and heart disease...We know the clock is ticking for some folks. For those with early diabetes, the sooner the [bariatric] surgery the more likely it is [for diabetes] to go into remission.”

Because the pandemic may be around for a while, “If we can make people [with obesity] safer ... because they’ve had surgery ... they may be better off,” should they get COVID-19 later, he pointed out.

Hutter noted that the ASMBS recorded a series of webinars, archived on the society’s website, with panels discussing in-depth issues to consider in prioritizing patients when restarting metabolic and bariatric surgery.

There are some differences of opinion, such as whether the sickest patients should be the first to have the surgeries upon reopening, or whether those individuals might be worse off if they contract COVID-19 in the perioperative setting.

“I don’t think there’s a right or wrong answer, but I think we have to figure out what’s right for the individual patient, considering their specific risks of having versus not having surgery, of waiting 1 month, 2 months, or 6 months. One thing we do know is that obesity is a significant disease.”
 

‘Before, during, and after COVID, obesity itself remains an epidemic’

Asked to comment on the ASMBS stance, Obesity Society president Lee M. Kaplan, MD, PhD, sent Medscape Medical News a statement.

“We do not fully understand which aspects of obesity pathophysiology ... are most responsible for the adverse COVID-19 outcomes, nor do we know the degree to which reduced access to care, social isolation, and other social and environmental determinants of health disproportionately affect COVID-19 patients with obesity,” he noted.

“At this early stage, we have not yet determined the impact of weight loss and various types of antiobesity therapies on these risks.”

Nonetheless, Kaplan said, “the extended COVID-19 pandemic underscores the importance of increasing, not diminishing, our commitment to understanding and treating obesity, using all available, evidence-based therapies, including lifestyle modification, antiobesity medications, bariatric surgery, and combinations thereof.”

As all health care delivery is being reorganized around the pandemic, Kaplan added: “Rethinking and changing our approach to obesity needs to be a central feature of this process.

“Before, during, and after COVID, obesity itself remains an epidemic. Its high global prevalence, increasing severity, and profound impact on all aspects of health and disease require that it be addressed more universally within the health care system, with the same commitment afforded to other chronic diseases.”

Obesity treatment isn’t generally considered an emergency, he noted, “because obesity is a chronic disease, whose adverse health effects often accumulate slowly and insidiously. Its generally slow progression allows for careful and coordinated care planning, and advanced scheduling of therapeutic interventions, including surgery. These characteristics, however, should not lead us to infer that treating obesity itself is optional.”

Kaplan has reported consulting for Boehringer Ingelheim, Fractyl, Gelesis, GI Dynamics, Johnson & Johnson, Novo Nordisk, Pfizer, Rhythm Pharmaceuticals, the National Institutes of Health, and the Department of State.

For those with early diabetes, the sooner the [bariatric] surgery the more likely it is [for diabetes] to go into remission.”

Because the pandemic may be around for a while, “If we can make people [with obesity] safer ... because they’ve had surgery ... they may be better off,” should they get COVID-19 later, he pointed out.

Hutter noted that the ASMBS recorded a series of webinars, archived on the society’s website, with panels discussing in-depth issues to consider in prioritizing patients when restarting metabolic and bariatric surgery.

There are some differences of opinion, such as whether the sickest patients should be the first to have the surgeries upon reopening, or whether those individuals might be worse off if they contract COVID-19 in the perioperative setting.

“I don’t think there’s a right or wrong answer, but I think we have to figure out what’s right for the individual patient, considering their specific risks of having versus not having surgery, of waiting 1 month, 2 months, or 6 months. One thing we do know is that obesity is a significant disease.”
 

‘Before, during, and after COVID, obesity itself remains an epidemic’

Asked to comment on the ASMBS stance, Obesity Society president Lee M. Kaplan, MD, PhD, sent Medscape Medical News a statement.

“We do not fully understand which aspects of obesity pathophysiology ... are most responsible for the adverse COVID-19 outcomes, nor do we know the degree to which reduced access to care, social isolation, and other social and environmental determinants of health disproportionately affect COVID-19 patients with obesity,” he noted.

“At this early stage, we have not yet determined the impact of weight loss and various types of antiobesity therapies on these risks.”

Nonetheless, Kaplan said, “the extended COVID-19 pandemic underscores the importance of increasing, not diminishing, our commitment to understanding and treating obesity, using all available, evidence-based therapies, including lifestyle modification, antiobesity medications, bariatric surgery, and combinations thereof.”

As all health care delivery is being reorganized around the pandemic, Kaplan added: “Rethinking and changing our approach to obesity needs to be a central feature of this process.

“Before, during, and after COVID, obesity itself remains an epidemic. Its high global prevalence, increasing severity, and profound impact on all aspects of health and disease require that it be addressed more universally within the health care system, with the same commitment afforded to other chronic diseases.”

Obesity treatment isn’t generally considered an emergency, he noted, “because obesity is a chronic disease, whose adverse health effects often accumulate slowly and insidiously. Its generally slow progression allows for careful and coordinated care planning, and advanced scheduling of therapeutic interventions, including surgery. These characteristics, however, should not lead us to infer that treating obesity itself is optional.”

Hutter has reported receiving honoraria from Ethicon and Medtronic, and is a consultant for Vicarious Surgical and Sigilon Therapeutics. Kaplan has reported consulting for Boehringer Ingelheim, Fractyl, Gelesis, GI Dynamics, Johnson & Johnson, Novo Nordisk, Pfizer, Rhythm Pharmaceuticals, the National Institutes of Health, and the Department of State.

Hospitalized cancer patients have a high risk of nosocomial COVID-19 that is associated with increased mortality, so these patients should be treated in COVID-free zones, according to researchers.

In an observational study of patients with COVID-19 and cancer, 19% of patients had COVID-19 acquired during a non-COVID-related hospital stay, and 81% had community-acquired COVID-19.

At a median follow-up of 23 days, the overall mortality rate was 28%. However, the all-cause mortality rate in patients with nosocomial COVID-19 was more than double that of patients with community-acquired COVID-19, at 47% and 23%, respectively.

Arielle Elkrief, MD, of the University of Montreal, reported these results during the AACR virtual meeting: COVID-19 and Cancer.

“This is the first report that describes a high rate of hospital-acquired COVID-19 in patients with cancer, at a rate of 19%,” Dr. Elkrief said. “This was associated with high mortality in both univariate and multivariate analyses.”

The study included 250 adults and 3 children with COVID-19 and cancer who were identified between March 3 and May 23, 2020. They ranged in age from 4 to 95 years, but the median age was 73 years.

All patients had either laboratory-confirmed (95%) or presumed COVID-19 (5%) and invasive cancer. The most common cancer types were similar to those seen in the general population. Lung and breast cancer were the most common, followed by lymphoma, prostate cancer, and colorectal cancer. Most patients were on active anticancer therapy, most often chemotherapy.

Most patients (n = 236) were residents of Quebec, but 17 patients were residents of British Columbia.

“It is important to note that Quebec was one of the most heavily affected areas in North America at the time of the study,” Dr. Elkrief said.
 

Outcomes by group

There were 206 patients (81%) who had community-acquired COVID-19 and 47 (19%) who had nosocomial COVID-19. The two groups were similar with respect to sex, performance status, and cancer stage. A small trend toward more patients on active therapy was seen in the nosocomial group, but the difference did not reach statistical significance.

The median overall survival was 27 days in the nosocomial group and 71 days in the community-acquired group (hazard ratio, 2.2; P = .002).

A multivariate analysis showed that nosocomial infection was “strongly and independently associated with death,” Dr. Elkrief said. “Other risk factors for poor prognosis included age, poor [performance] status, and advanced stage of cancer.”

There were no significant differences between the hospital-acquired and community-acquired groups for other outcomes, including oxygen requirements (43% and 47%, respectively), ICU admission (13% and 11%), need for mechanical ventilation (6% and 5%), or length of stay (median, 9.5 days and 8.5 days).

The low rate of ICU admission, considering the mortality rate of 28%, “could reflect that patients with cancer are less likely to be admitted to the ICU,” Dr. Elkrief noted.
 

Applying the findings to practice

The findings reinforce the importance of adherence to stringent infection control guidelines to protect vulnerable patients, such as those with cancer, Dr. Elkrief said.

In ambulatory settings, this means decreasing in-person visits through increased use of teleconsultations, and for those who need to be seen in person, screening for symptoms or use of polymerase chain reaction testing should be used when resources are available, she said.

“Similar principles apply to chemotherapy treatment units,” Dr. Elkrief said. She added that staff must avoid cross-contamination between COVID and COVID-free zones, and that “dedicated personnel and equipment should be maintained and separate between these two zones.

“Adequate protective personal equipment and strict hand hygiene protocols are also of utmost importance,” Dr. Elkrief said. “The threat of COVID-19 is not behind us, and so we continue to enforce these strategies to protect our patients.”

Session moderator Gypsyamber D’Souza, PhD, an infectious disease epidemiologist at Johns Hopkins University in Baltimore, raised the question of whether the high nosocomial infection and death rate in this study was related to patients having more severe disease because of underlying comorbidities.

Dr. Elkrief explained that the overall mortality rate was indeed higher than the 13% reported in other studies, and it may reflect an overrepresentation of hospitalized or more severely ill patients in the cohort.

However, the investigators made every effort to include all patients with both cancer and COVID-19 by using systematic screening of inpatient and outpatients lists and registries.

Further, the multivariate analysis included both inpatients and outpatients and adjusted for known negative prognostic factors for COVID-19 outcomes. These included increasing age, poor performance status, and different comorbidities.

The finding that nosocomial infection was an independent predictor of death “pushed us to look at nosocomial infection as a new independent risk factor,” Dr. Elkrief said.

Dr. Elkrief reported grant support from AstraZeneca. Dr. D’Souza did not report any disclosures.

Low plasma vitamin D levels emerged as an independent risk factor for COVID-19 infection and hospitalization in a large, population-based study.

Participants positive for COVID-19 were 50% more likely to have low vs normal 25(OH)D levels in a multivariate analysis that controlled for other confounders, for example.

The take home message for physicians is to “test patients’ vitamin D levels and keep them optimal for the overall health – as well as for a better immunoresponse to COVID-19,” senior author Milana Frenkel-Morgenstern, PhD, head of the Cancer Genomics and BioComputing of Complex Diseases Lab at Bar-Ilan University in Ramat Gan, Israel, said in an interview.

The study was published online July 23 in The FEBS Journal.

Previous and ongoing studies are evaluating a potential role for vitamin D to prevent or minimize the severity of SARS-CoV-2 infection, building on years of research addressing vitamin D for other viral respiratory infections. The evidence to date regarding COVID-19, primarily observational studies, has yielded mixed results.

Multiple experts weighed in on the controversy in a previous report. Many point out the limitations of observational data, particularly when it comes to ruling out other factors that could affect the severity of COVID-19 infection. In addition, in a video report, JoAnn E. Manson, MD, DrPH, of Harvard Medical School in Boston, cited an observational study from three South Asian hospitals that found more severe COVID-19 patients had lower vitamin D levels, as well as other “compelling evidence” suggesting an association.

Dr. Frenkel-Morgenstern and colleagues studied data for 7,807 people, of whom 10.1% were COVID-19 positive. They assessed electronic health records for demographics, potential confounders, and outcomes between February 1 and April 30.

Participants positive for COVID-19 tended to be younger and were more likely to be men and live in a lower socioeconomic area, compared with the participants who were negative for COVID-19, in a univariate analysis.

Key findings

A higher proportion of COVID-19–positive patients had low plasma 25(OH)D concentrations, about 90% versus 85% of participants who were negative for COVID-19. The difference was statistically significant (P < .001). Furthermore, the increased likelihood for low vitamin D levels among those positive for COVID-19 held in a multivariate analysis that controlled for demographics and psychiatric and somatic disorders (adjusted odds ratio, 1.50). The difference remained statistically significant (P < .001).

The study also was noteworthy for what it did not find among participants with COVID-19. For example, the prevalence of dementia, cardiovascular disease, chronic lung disorders, and hypertension were significantly higher among the COVID-19 negative participants.

“Severe social contacts restrictions that were imposed on all the population and were even more emphasized in this highly vulnerable population” could explain these findings, the researchers noted.

“We assume that following the Israeli Ministry of Health instructions, patients with chronic medical conditions significantly reduced their social contacts” and thereby reduced their infection risk.

In contrast to previous reports, obesity was not a significant factor associated with increased likelihood for COVID-19 infection or hospitalization in the current study.

The researchers also linked low plasma 25(OH)D level to an increased likelihood of hospitalization for COVID-19 infection (crude OR, 2.09; P < .05).

After controlling for demographics and chronic disorders, the aOR decreased to 1.95 (P = .061) in a multivariate analysis. The only factor that remained statistically significant for hospitalization was age over 50 years (aOR, 2.71; P < .001).

Implications and future plans

The large number of participants and the “real world,” population-based design are strengths of the study. Considering potential confounders is another strength, the researchers noted. The retrospective database design was a limitation.

Going forward, Dr. Frenkel-Morgenstern and colleagues will “try to decipher the potential role of vitamin D in prevention and/or treatment of COVID-19” through three additional studies, she said. Also, they would like to conduct a meta-analysis to combine data from different countries to further explore the potential role of vitamin D in COVID-19.

“A compelling case”

“This is a strong study – large, adjusted for confounders, consistent with the biology and other clinical studies of vitamin D, infections, and COVID-19,” Wayne Jonas, MD, a practicing family physician and executive director of Samueli Integrative Health Programs, said in an interview.

Because the research was retrospective and observational, a causative link between vitamin D levels and COVID-19 risk cannot be interpreted from the findings. “That would need a prospective, randomized study,” said Dr. Jonas, who was not involved with the current study.

However, “the study makes a compelling case for possibly screening vitamin D levels for judging risk of COVID infection and hospitalization,” Dr. Jonas said, “and the compelling need for a large, randomized vitamin D supplement study to see if it can help prevent infection.”

“Given that vitamin D is largely safe, such a study could be done quickly and on healthy people with minimal risk for harm,” he added.
 

More confounders likely?

“I think the study is of interest,” Naveed Sattar, PhD,  professor of metabolic medicine at the University of Glasgow, who also was not affiliated with the research, said in an interview.

“Whilst the authors adjusted for some confounders, there is a strong potential for residual confounding,” said Dr. Sattar, a coauthor of a UK Biobank study that did not find an association between vitamin D stages and COVID-19 infection in multivariate models.

For example, Dr. Sattar said, “Robust adjustment for social class is important since both Vitamin D levels and COVID-19 severity are both strongly associated with social class.” Further, it remains unknown when and what time of year the vitamin D concentrations were measured in the current study.

“In the end, only a robust randomized trial can tell us whether vitamin D supplementation helps lessen COVID-19 severity,” Dr. Sattar added. “I am not hopeful we will find this is the case – but I am glad some such trials are [ongoing].”

Dr. Frenkel-Morgenstern received a COVID-19 Data Sciences Institute grant to support this work. Dr. Frenkel-Morgenstern, Dr. Jonas, and Dr. Sattar have disclosed no relevant financial relationships.

The study also was noteworthy for what it did not find among participants with COVID-19. For example, the prevalence of dementia, cardiovascular disease, chronic lung disorders, and hypertension were significantly higher among the COVID-19 negative participants.

“Severe social contacts restrictions that were imposed on all the population and were even more emphasized in this highly vulnerable population” could explain these findings, the researchers noted.

“We assume that following the Israeli Ministry of Health instructions, patients with chronic medical conditions significantly reduced their social contacts” and thereby reduced their infection risk.

In contrast to previous reports, obesity was not a significant factor associated with increased likelihood for COVID-19 infection or hospitalization in the current study.

The researchers also linked low plasma 25(OH)D level to an increased likelihood of hospitalization for COVID-19 infection (crude OR, 2.09; P < .05).

After controlling for demographics and chronic disorders, the aOR decreased to 1.95 (P = .061) in a multivariate analysis. The only factor that remained statistically significant for hospitalization was age over 50 years (aOR, 2.71; P < .001).

Implications and future plans

The large number of participants and the “real world,” population-based design are strengths of the study. Considering potential confounders is another strength, the researchers noted. The retrospective database design was a limitation.

Going forward, Dr. Frenkel-Morgenstern and colleagues will “try to decipher the potential role of vitamin D in prevention and/or treatment of COVID-19” through three additional studies, she said. Also, they would like to conduct a meta-analysis to combine data from different countries to further explore the potential role of vitamin D in COVID-19.

“A compelling case”

“This is a strong study – large, adjusted for confounders, consistent with the biology and other clinical studies of vitamin D, infections, and COVID-19,” Wayne Jonas, MD, a practicing family physician and executive director of Samueli Integrative Health Programs, said in an interview.

Because the research was retrospective and observational, a causative link between vitamin D levels and COVID-19 risk cannot be interpreted from the findings. “That would need a prospective, randomized study,” said Dr. Jonas, who was not involved with the current study.

However, “the study makes a compelling case for possibly screening vitamin D levels for judging risk of COVID infection and hospitalization,” Dr. Jonas said, “and the compelling need for a large, randomized vitamin D supplement study to see if it can help prevent infection.”

“Given that vitamin D is largely safe, such a study could be done quickly and on healthy people with minimal risk for harm,” he added.
 

More confounders likely?

“I think the study is of interest,” Naveed Sattar, PhD,  professor of metabolic medicine at the University of Glasgow, who also was not affiliated with the research, said in an interview.

“Whilst the authors adjusted for some confounders, there is a strong potential for residual confounding,” said Dr. Sattar, a coauthor of a UK Biobank study that did not find an association between vitamin D stages and COVID-19 infection in multivariate models.

For example, Dr. Sattar said, “Robust adjustment for social class is important since both Vitamin D levels and COVID-19 severity are both strongly associated with social class.” Further, it remains unknown when and what time of year the vitamin D concentrations were measured in the current study.

“In the end, only a robust randomized trial can tell us whether vitamin D supplementation helps lessen COVID-19 severity,” Dr. Sattar added. “I am not hopeful we will find this is the case – but I am glad some such trials are [ongoing].”

Dr. Frenkel-Morgenstern received a COVID-19 Data Sciences Institute grant to support this work. Dr. Frenkel-Morgenstern, Dr. Jonas, and Dr. Sattar have disclosed no relevant financial relationships.
