Second woman spontaneously clears HIV: ‘We think more are out there’
It sounds like a fairy tale steeped in HIV stigma: A woman wakes up one morning and, poof, the HIV she’s been living with for 8 years is gone. But for a 30-year-old Argentinian woman from the aptly named village of Esperanza, that’s close to the truth, according to an article published in Annals of Internal Medicine.
The woman, the so-called Esperanza Patient, appears to be the second person whose immune system cleared the virus without the use of stem cell transplantation. The first was Loreen Willenberg, a California woman who, after living with HIV for 27 years, no longer had replicating HIV in her system. That case was reported last year.
“That’s the beauty of this name, right? Esperanza,” said Xu Yu, MD, principal investigator of the Ragon Institute of Massachusetts General Hospital, the Massachusetts Institute of Technology, and Harvard University, Boston, referring to the Spanish word for “hope.” “This makes us hopeful that a natural cure of HIV is actually possible.”
Two other people appear to have cleared HIV, but only after full replacement of the immune system via stem cell transplantation – the Berlin Patient, Timothy Ray Brown, and the London Patient. Another man, from Brazil, appeared to have an undetectable viral load after receiving intensified antiretroviral treatment plus supplemental vitamin B3.
The rarest of the rare
The Esperanza Patient is among a rare group of people living with HIV called elite controllers. These people’s immune systems can control HIV without antiretrovirals. Most elite controllers’ immune systems, however, can’t mount the immune attack necessary to eliminate all replicating HIV from their systems. Instead, their immune systems control the virus without affecting the reservoirs where HIV continues to make copies of itself and can spread.
The Esperanza Patient and Ms. Willenberg, however, appear to be the rarest of the rare. Their own immune systems seem not only to have stopped HIV replication outside of reservoirs but also to have stormed those reservoirs and killed all virus that might have continued to replicate.
The two women are connected in another way: At an HIV conference in 2019, Dr. Yu was presenting data on Ms. Willenberg’s case. At that conference, she met Natalia Laufer, MD, PhD, associate researcher at the Instituto de Investigaciones Biomédicas en Retrovirs y SIDA at the University of Buenos Aires. Dr. Laufer had been studying the Esperanza Patient at the time and asked Dr. Yu whether she and her team at the Ragon Institute could help her sequence the patient’s HIV genome to see whether, indeed, the virus had been spontaneously cleared from the patient’s system.
So that’s what the pair did, in collaboration with several other researchers into cures for HIV. The Esperanza Patient first acquired HIV in 2013, but in the 8 years that followed, results of 10 conventional viral load tests indicated the virus was undetectable (that is, below the level of quantification for standard technology). During that time, the woman’s boyfriend, from whom she had acquired HIV, died of AIDS-defining illnesses. She subsequently married and had a baby. Both her partner and baby are HIV negative. She only received HIV treatment for 6 months while she was pregnant.
A fossil record of HIV
Yet, there was still HIV in the woman’s system. Dr. Laufer and Dr. Yu wanted to know whether that HIV was transmissible or whether it was a relic from when HIV was still replicating and was now defective and incapable of replicating. They performed extensive genome sequencing on nearly 1.2 billion cells that Dr. Laufer had taken from the patient’s blood in 2017, 2018, 2019, and 2020, an additional 503 million cells that were from the placenta of the baby she gave birth to in 2020, and 150 million resting CD4 T cells. Proviral sequencing was undertaken of the full DNA of the HIV to detect whether the virus was still intact. The DNA was then analyzed by use of an algorithm and was tested for mutations. The investigators tested the patient’s CD4 cells to determine whether the cells still harbored any latent HIV.
In this way, they conducted a full viral workup using tests that are far more sensitive than the viral load tests the woman had undergone in the clinic. The investigators then assessed the patient’s immune system to see what the various cells of the immune system could tell them about how well her natural immune system could identify and kill HIV. They isolated the Esperanza Patient’s immune cells and subjected those cells to HIV in the lab to see whether the cells could detect and eliminate the virus.
And just to be safe, they checked to make sure there were no antiretroviral drugs in the patient’s system.
What they found was that without treatment, her CD4 count hovered around 1,000 cells – a sign of a functioning immune system. DNA sequences revealed large chunks of missing DNA, and one sequence had an immune-induced hypermutation. In total, seven proviruses were found, but none were capable of replicating. The CD4 cells they evaluated showed no evidence of latent HIV.
In other words, they had uncovered a fossil record.
“These HIV-1 DNA products clearly indicate that this person was infected with HIV-1 in the past and that active cycles of viral replication had occurred at one point,” Dr. Yu and colleagues write in their recent article.
What may be more useful to researchers looking to turn this spontaneous cure into treatment for millions of people living with active HIV was the evidence that the woman’s immune system had trained itself to attack HIV through a number of genetic mutations. What they found, the researchers write, was evidence of “an incomplete seroconversion” – that is, when the patient was acquiring HIV, the infection was stopped in its tracks.
Yet, Dr. Yu and colleagues say that they can’t prove that the woman is fully cured of HIV.
“Although this might sound unsatisfying, it reflects an intrinsic limitation of scientific research,” they write. “Scientific concepts can never be proved through empirical data collection; they can only be disproved.”
There are more out there
Are these women the only ones to have spontaneously cleared HIV? That’s the question, said Carl Dieffenbach, PhD, director of the Division of AIDS at the National Institute of Allergy and Infectious Diseases at the National Institutes of Health. Just like they can’t disprove that the women cured themselves, they can’t prove that she and Ms. Willenberg are the only two people to have experienced this cure.
“We’re all struggling with this,” Dr. Dieffenbach told this news organization. “The goal is to get enough of these people so maybe there’s a road map to how to induce, trigger, change immunity. But this could well be a unique event at the time of initiation of infection. We just don’t know.”
What is needed, Dr. Yu said, is for clinicians to reach out to them regarding cases that could mimic the cases of Ms. Willenberg and the Esperanza Patient. Elaborate testing could then be conducted to see whether these cases are similar to those of Ms. Willenberg and the Esperanza Patient.
“We do think there are more out there,” Dr. Yu said in an interview.
Asked whether we’re still far away from applying these one-off cures to the millions of people taking HIV treatment daily, Dr. Yu responded, “We might be close. That’s the beauty of scientific discovery. We don’t know, but that’s why we need more engagement of the community and care providers to help us.”
The research was funded by the Bill and Melinda Gates Foundation and the National Institutes of Health. Dr. Yu and Dr. Dieffenbach have reported no relevant financial relationships.

Text-based COVID monitoring system could reduce deaths, relieve ED in winter surge
COVID Watch, a text message–based remote monitoring program developed by the University of Pennsylvania Health System, was associated with a 68% reduction in the risk of death, compared with those who received usual care. This was the main finding of a paper published in the Annals of Internal Medicine.
The investigators also determined that patients who enrolled in the program were more likely to seek care in the ED and when they did, they came in on average 2 days sooner than those who received usual care.
“When our clinical team designed COVID Watch the goal was to facilitate hospital care for patients who require it, while supporting access to care for patients who can safely remain at home,” study author M. Kit Delgado, MD, MS, an assistant professor of emergency medicine and epidemiology at Penn Presbyterian Medical Center in Philadelphia, said in an interview.
Researchers had initially hoped COVID Watch would relieve pressure on EDs, Dr. Delgado said.
Significantly lower mortality seen among COVID Watch group
For the study, Dr. Delgado and colleagues enrolled 3,488 patients in COVID Watch and 4,377 in the usual care group to compare outcomes at 30 and 60 days.
“We didn’t include patients who were diagnosed with COVID in the ER or hospital, so this is a lower-risk cohort of patients who test positive in outpatient settings,” Dr. Delgado noted. “Outpatients who received usual care and COVID Watch both had relatively low mortality, but it was significantly lower in those who were in COVID Watch.”
The researchers found that 3 patients in the COVID Watch group died within 30 days of their enrollment, compared with 12 in the control group. At 60 days after enrollment, 5 people within COVID Watch died, compared with 16 not using the system. More than one-third of the deaths in the usual care group occurred outside the hospital, compared with zero deaths among those in COVID Watch.
More than half of program participants were Black or Latino
The messaging system also reduced mortality rates among “all major racial and ethnic subgroups,” the researchers said, with more than 50% of the patients enrolled in COVID Watch having been Black or Latino.
“This is important because Black and Hispanic communities have experienced higher exposure and infection rates, decreased access to care, and have had higher mortality rates,” Dr. Delgado said. “Therefore, the results imply that this type of program could play a role in decreasing disparities in COVID outcomes if scaled more broadly.”
Outside expert: COVID Watch bring new approach to digital health monitoring
The study not only highlights the efficacy and sustainment of the COVID Watch program, but it sheds light on the possibility of using text message monitoring systems on other chronic disease conditions, said Jamie Faro, PhD, who was not involved in the study.
“It brings a new approach to health monitoring using digital means, which may lessen the burden on health care providers and be more cost effective than usual care approaches,” said Dr. Faro, who is assistant professor at the department of population and quantitative health sciences at the University of Massachusetts, Worcester. “Text messaging, which is used by over 80% of Americans, can allow us to reach a large percentage of the population for remote health care monitoring.”
Researchers of the current study said the findings “reveal a model for outpatient health system management of patients with COVID-19 and possibly other conditions where the early detection of clinical declines is critical.” Dr. Faro said that COVID Watch can have a measurable impact on an outcome that is truly life or death. However, it would be critical to understand how to reach those who either “were not offered or refused to take part in the program.”
The authors of the paper and Dr. Faro had no disclosures.

FROM ANNALS OF INTERNAL MEDICINE
Children and COVID: Youngest vaccinees off to a slower start
Specific figures for children aged 5-11 years are not yet available, but CDC data show that 1.55 million children under the age of 12 years had received at least one dose of COVID-19 vaccine as of Nov. 15, of whom almost 204,000 already had been vaccinated before Nov. 2. For children aged 12-15, the first 2 weeks after approval on May 12 produced almost 2.1 million vaccine initiations, according to the CDC’s COVID Data Tracker.
That dataset reveals several other noteworthy differences between the two age groups in the 10 days after approval:
- There were over 7,000 vaccine initiations on the first day in the 12-15 group; the younger group had 32.
- The older children reached 100,000 per day in 3 days; the younger children took 8 days.
- The older group topped 200,000 vaccinations per day on six different days; the younger group didn’t get above 175,000.
Children under 12 made up 27.5% of vaccine initiations in all age groups during the 2 weeks from Nov. 2 to Nov. 15, versus 3.4% for 12- to 15-year-olds and 1.2% for 16- and 17-year-olds, the CDC said, while also reporting that 3.6% of children under age 12 had received at least one dose of the COVID vaccine, compared with 57.8% of those aged 12-15 and 64.4% of 16- to 17-year-olds.
Meanwhile, the first full week of November marked the second consecutive increase in the number of weekly child COVID cases, with 122,000 reported for Nov. 5-11. The number of new cases has now surpassed 100,000 for 14 consecutive weeks, the American Academy of Pediatrics and the Children’s Hospital Association said in their weekly COVID report. That report, which covers state health departments, has not included current information from Alabama, Nebraska, and Texas since the summer.
Regionally, the increases over the past 2 weeks were spread out among the East, the Midwest, and the West, while the decline that had been going on for several weeks in the South has largely come to a halt. The states with the highest percent increases over those 2 weeks are all in New England: Maine, New Hampshire, and Vermont, the AAP and CHA noted. In a separate report, the AAP said that Vermont has the second-highest child vaccination rate (81%) in the country, just behind Massachusetts (82%).
Specific figures for children aged 5-11 years are not yet available, but CDC data show that 1.55 million children under the age of 12 years had received at least one dose of COVID-19 vaccine as of Nov. 15, of whom almost 204,000 already had been vaccinated before Nov. 2. For children aged 12-15, the first 2 weeks after approval on May 12 produced almost 2.1 million vaccine initiations, according to the CDC’s COVID Data Tracker.
That dataset reveals several other noteworthy differences between the two age groups in the 10 days after approval:
- There were over 7,000 vaccine initiations on the first day in the 12-15 group; the younger group had 32.
- The older children reached 100,000 per day in 3 days; the younger children took 8 days.
- The older group topped 200,000 vaccinations per day on six different days; the younger group didn’t get above 175,000.
Children under 12 made up 27.5% of vaccine initiations in all age groups during the 2 weeks from Nov. 2 to Nov. 15, versus 3.4% for 12- to 15-year-olds and 1.2% for 16- and 17-year-olds, the CDC said, while also reporting that 3.6% of children under age 12 had received at least one dose of the COVID vaccine, compared with 57.8% of those aged 12-15 and 64.4% of 16- to 17-year-olds.
Meanwhile, the first full week of November marked the second consecutive increase in the number of weekly child COVID cases, with 122,000 reported for Nov. 5-11.

To boost HIV screening, ED nurses need institutional support
, according to a national survey of ED nurses. Nearly 43% of respondents said they had received “little” or “very little” HIV education as part of their professional development and practice.
This lack of continuing HIV education “often translated into attitudes that did not support the policy” of routine HIV screening in EDs, lead author Candace Elam, DNP, a family nurse practitioner at the Institute of Family Health in the Bronx, New York City, told this news organization. “But more than individual attitudes, what came out most clearly in the research was that organizational support for HIV screening in EDs was the one factor that could make or break whether an emergency nurse performs HIV screening,” she said. This includes working routine HIV screening into ED workflows and providing resources to streamline screening and testing efforts.
In 2006, the Centers for Disease Control and Prevention released guidance recommending routine HIV screening in all healthcare settings, including urgent care and EDs. Elam, who conducted the research as a student at Rutgers University School of Nursing in New Brunswick, N.J., noticed during her time as an ED nurse that, while her department had a policy supporting routine HIV screening, the practice was not consistent across all nursing staff. To find out how HIV screening varied nationally, Elam ran a national survey from Oct. through Dec. 2020, recruiting participants both by email outreach and Facebook.
In the 30- to 45-minute survey, respondents reported:
- Demographic information
- Knowledge of the CDC HIV screening recommendations
- Workplace HIV screening policy
- Self-reported performance of HIV screening
- Beliefs and attitudes pertaining to HIV screening
Overall, 371 individuals from 43 states filled out at least some part of the survey, and 171 individuals completed it. Of the 251 individuals who answered whether their EDs routinely conducted HIV screening, 76.9% responded affirmatively. Overall, 28.5% of respondents thought HIV screening was “not important” or “not at all important.” Nearly half – 47.6% – reported never offering HIV testing to all eligible patients regardless of risk factors, and only 14.3% reported offering testing all of the time. Only 25% of participants said they received “adequate” or “a lot” of HIV-related nursing education, and 42.9% reported “little” or “very little” education.
“For the most part, those of us working in hospitals, all the education that we get about HIV took place in school,” Elam said. “So, if you went to school in the early 2000s or in the 1990s, you don’t know much else.” Elam noted that she keeps informed on HIV research issues because it is an area of interest, but the hospital she had worked at did not contribute much to her knowledge.
Elam also found that in practice there were several barriers to performing screening, such as lack of availability of a dedicated HIV educator, tester, or counselors; not knowing where to refer patients who had a positive HIV test result; and insufficient time to address positive HIV test results in ED practice.
“A lot of these things are outside an individual nurse’s control,” said Elam, and can result in missing patients who would benefit from care. Lisa Leimer, RN, a nurse at Primary Health Care in Des Moines, works with patients after they have been diagnosed with HIV, but noted that many of her patients could have been identified earlier. “Once we get someone, you look back at medical records and you see that they have been in and out of the hospital,” she said. “There’s been multiple encounters,” she said.
Prioritizing HIV screening in all healthcare settings and including HIV education for all medical professionals – not just nurses – could help in the continuing battle against HIV. “So much has changed in the world of HIV,” she said. “We’re trying to end the epidemic, and it could happen if we identified, diagnosed, and treated the people that are living with it.”
Elam and Leimer have reported no relevant financial relationships.

Children and COVID: New cases up again after dropping for 8 weeks
As children aged 5-11 years began to receive the first officially approved doses of COVID-19 vaccine, new pediatric cases increased after 8 consecutive weeks of declines, according to the American Academy of Pediatrics and the Children’s Hospital Association.
Weekly cases peaked at almost 252,000 in early September and then dropped for 8 straight weeks before this latest rise, the AAP and the CHA said in their weekly COVID report, which is based on data reported by 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.
The end of that 8-week drop, unfortunately, allowed another streak to continue: New cases have been above 100,000 for 13 consecutive weeks, the AAP and CHA noted.
The cumulative COVID count in children as of Nov. 4 was 6.5 million, the AAP/CHA said, although that figure does not fully cover Alabama, Nebraska, and Texas, which stopped public reporting over the summer. The Centers for Disease Control and Prevention, with input from all states and territories, puts the total through Nov. 8 at almost 5.7 million cases in children under 18 years of age, while most states define a child as someone aged 0-19 years.
As for the newest group of vaccinees, the CDC said that “updated vaccination data for 5-11 year-olds will be added to COVID Data Tracker later this week,” meaning the week of Nov. 7-13. Currently available data, however, show that almost 157,000 children under age 12 initiated vaccination in the 14 days ending Nov. 8, which was more than those aged 12-15 and 16-17 years combined (127,000).
Among those older groups, the CDC reports that 57.1% of 12- to 15-year-olds have received at least one dose and 47.9% are fully vaccinated, while 64.0% of those aged 16-17 have gotten at least one dose and 55.2% are fully vaccinated. Altogether, about 13.9 million children under age 18 have gotten at least one dose and almost 11.6 million are fully vaccinated, according to the CDC.

72-year-old man • fever • new-onset urinary frequency • altered mental state • Dx?
THE CASE
A 72-year-old man was admitted to our Dallas hospital with a 4-day history of fevers and new-onset urinary frequency. He did not report any joint pain, sick contacts, or recent travel or recall any skin findings (rashes, insect bites). Past medical history was significant for hypertension, hyperlipidemia, diabetes, benign prostatic hyperplasia, recurrent urinary tract infections, and lumbar radiculopathy.
Initial signs and symptoms were suggestive of sepsis: a temperature of 102.7 °F, tachycardia, and a suspected genitourinary infection. This was supported by initial labs concerning for end-organ damage: elevated creatinine of 1.58 mg/dL (reference range, 0.67-1.17 mg/dL), elevated international normalized ratio (INR) of 1.6 (reference range, 0.9-1.1), hemoglobin of 12.8 g/dL (reference range, 13.5 - 17.5 g/dL), and platelet count of 99 ×109/L (reference range, 160-383 ×109/L).
Over the next several days, the patient’s condition worsened, and he experienced a decline in mental status, despite initiation of broad-spectrum antibiotics and fluid resuscitation. Although lumbar puncture was warranted, neither Neurology nor Interventional Radiology were willing to risk the procedure given the patient’s worsening hemoglobin (8.3 g/dL) and platelet count (51 ×109/L).
Preliminary work-up included a urinalysis negative for leukocytes, nitrites, and bacteria—despite a urine culture that showed gram-positive cocci. His chest x-ray was unremarkable, and computed tomography of his brain showed generalized atrophy without acute changes. The work-up was expanded to fungal cultures and immunochemical assays. Empiric treatment with micafungin and acyclovir was started without improvement.
Further conversation with family revealed that the patient liked to spend time outdoors and he’d had a similar episode in which he’d been diagnosed with an unknown disease from an insect bite. Pertinent negative tests included: HIV, syphilis, rapid heterophile antibody, influenza, respiratory virus panel, blood culture, fungal culture, antineutrophil cytoplasmic antibodies, histoplasmosis, brucellosis, malaria, Epstein-Barr virus, cytomegalovirus, and parvovirus. Coxiella burnetii and West Nile virus immunoglobulin (Ig) G were positive, suggesting a prior exposure.
THE DIAGNOSIS
Given these new findings and reported outdoor activities, Infectious Diseases recommended we start our patient on doxycycline for possible rickettsia infection. On Day 8, doxycycline 200 mg IV once daily was started. (The IV form was initiated due to the patient’s altered mentation.) The patient started to show improvement, and on Day 14, an immunofluorescence antibody (IFA) assay revealed Rickettsia typhi IgM titers 1:512 (< 1:64) and IgG titers 1:256 (< 1:64), consistent with a diagnosis of murine (endemic) typhus.
DISCUSSION
Murine typhus is an acute febrile disease caused by R typhi, an obligate, intracellular gram-negative organism.1 Worldwide, transmission to humans occurs mainly from infected rat fleas harbored by rodents. In the United States, it’s been suggested that opossums serve as an important reservoir in peri-domestic settings, with cat fleas as vectors.2-4 The disease is endemic to southern California and south Texas.4
Continue to: Incidence of murine typhus
Incidence of murine typhus has declined in the United States since 1945 with the use of the insecticide dichlorodiphenyltrichloroethane (DDT). However, a recent rise in murine typhus cases—likely due to ecological changes—makes timely diagnosis and treatment essential.5 An epidemiologic study of 1762 confirmed cases in Texas from 2003 to 2013 found an increase in the number of cases and an expansion of the geographic areas impacted.3 Thus, in the work-up of acute fever of unknown origin, it is not unreasonable to include murine typhus in the differential.
Murine typhus can be difficult to diagnose due to nonspecific clinical manifestation.3,4 A 2016 systematic review of 2074 patients reported common symptoms of fever, headache, malaise, chills, and myalgia.6 The most common laboratory abnormalities in adults were elevated aminotransferases, lactate dehydrogenase, hypoalbuminemia, and thrombocytopenia.6 A 4-fold increase in typhus group IgM or IgG-specific antibody titer by IFA is supportive of diagnosis.4
The differential diagnosis included urosepsis, prostatitis, syphilis, HIV, and meningitis. However, lack of response to broad-spectrum antibiotics and antifungals made a diagnosis of urologic infection unlikely. A negative sexually transmitted infection screen ruled out syphilis and HIV.
Treatment may begin without a definitive diagnosis
Serologic testing with IFA is the preferred diagnostic method; however, a definitive diagnosis is not needed before treatment can be initiated. Doxycycline is the first-line therapy for all rickettsioses. Adults are advised to take doxycycline 200 mg orally once, followed by 100 mg twice daily until the patient improves, has been afebrile for 48 hours, and has received treatment for at least 7 days.7 Oral chloramphenicol is considered a second-line treatment; however it is not available in the United States and is associated with adverse hematologic effects.7
Our patient responded remarkably well to the doxycycline. After a 14-day course was completed, he was discharged to a skilled nursing facility for physical rehabilitation.

THE TAKEAWAY
Rickettsia diseases, such as murine typhus, should be considered in the differential if a patient presents with a worsening clinical picture of unresolved delirium; fever despite use of broad-spectrum antibiotics, antifungals, and antivirals; and a history of potential outdoor exposure. Sources include opossums or cats when flea contact is likely. Rickettsia diseases belong in the differential when there is a history of travel to tropical areas, as well. All suspected cases should be reported to the local health department.

THE CASE
A 72-year-old man was admitted to our Dallas hospital with a 4-day history of fevers and new-onset urinary frequency. He did not report any joint pain, sick contacts, or recent travel or recall any skin findings (rashes, insect bites). Past medical history was significant for hypertension, hyperlipidemia, diabetes, benign prostatic hyperplasia, recurrent urinary tract infections, and lumbar radiculopathy.
Initial signs and symptoms were suggestive of sepsis: a temperature of 102.7 °F, tachycardia, and a suspected genitourinary infection. This was supported by initial labs concerning for end-organ damage: elevated creatinine of 1.58 mg/dL (reference range, 0.67-1.17 mg/dL), elevated international normalized ratio (INR) of 1.6 (reference range, 0.9-1.1), hemoglobin of 12.8 g/dL (reference range, 13.5 - 17.5 g/dL), and platelet count of 99 ×109/L (reference range, 160-383 ×109/L).
Over the next several days, the patient’s condition worsened, and he experienced a decline in mental status, despite initiation of broad-spectrum antibiotics and fluid resuscitation. Although lumbar puncture was warranted, neither Neurology nor Interventional Radiology were willing to risk the procedure given the patient’s worsening hemoglobin (8.3 g/dL) and platelet count (51 ×109/L).
Preliminary work-up included a urinalysis negative for leukocytes, nitrites, and bacteria—despite a urine culture that showed gram-positive cocci. His chest x-ray was unremarkable, and computed tomography of his brain showed generalized atrophy without acute changes. The work-up was expanded to fungal cultures and immunochemical assays. Empiric treatment with micafungin and acyclovir was started without improvement.
Further conversation with family revealed that the patient liked to spend time outdoors and he’d had a similar episode in which he’d been diagnosed with an unknown disease from an insect bite. Pertinent negative tests included: HIV, syphilis, rapid heterophile antibody, influenza, respiratory virus panel, blood culture, fungal culture, antineutrophil cytoplasmic antibodies, histoplasmosis, brucellosis, malaria, Epstein-Barr virus, cytomegalovirus, and parvovirus. Coxiella burnetii and West Nile virus immunoglobulin (Ig) G were positive, suggesting a prior exposure.
THE DIAGNOSIS
Given these new findings and reported outdoor activities, Infectious Diseases recommended we start our patient on doxycycline for possible rickettsia infection. On Day 8, doxycycline 200 mg IV once daily was started. (The IV form was initiated due to the patient’s altered mentation.) The patient started to show improvement, and on Day 14, an immunofluorescence antibody (IFA) assay revealed Rickettsia typhi IgM titers 1:512 (< 1:64) and IgG titers 1:256 (< 1:64), consistent with a diagnosis of murine (endemic) typhus.
DISCUSSION
Murine typhus is an acute febrile disease caused by R typhi, an obligate, intracellular gram-negative organism.1 Worldwide, transmission to humans occurs mainly from infected rat fleas harbored by rodents. In the United States, it’s been suggested that opossums serve as an important reservoir in peri-domestic settings, with cat fleas as vectors.2-4 The disease is endemic to southern California and south Texas.4
Continue to: Incidence of murine typhus
Incidence of murine typhus has declined in the United States since 1945 with the use of the insecticide dichlorodiphenyltrichloroethane (DDT). However, a recent rise in murine typhus cases—likely due to ecological changes—makes timely diagnosis and treatment essential.5 An epidemiologic study of 1762 confirmed cases in Texas from 2003 to 2013 found an increase in the number of cases and an expansion of the geographic areas impacted.3 Thus, in the work-up of acute fever of unknown origin, it is not unreasonable to include murine typhus in the differential.
Murine typhus can be difficult to diagnose due to nonspecific clinical manifestation.3,4 A 2016 systematic review of 2074 patients reported common symptoms of fever, headache, malaise, chills, and myalgia.6 The most common laboratory abnormalities in adults were elevated aminotransferases, lactate dehydrogenase, hypoalbuminemia, and thrombocytopenia.6 A 4-fold increase in typhus group IgM or IgG-specific antibody titer by IFA is supportive of diagnosis.4
The differential diagnosis included urosepsis, prostatitis, syphilis, HIV, and meningitis. However, lack of response to broad-spectrum antibiotics and antifungals made a diagnosis of urologic infection unlikely. A negative sexually transmitted infection screen ruled out syphilis and HIV.
Treatment may begin without a definitive diagnosis
Serologic testing with IFA is the preferred diagnostic method; however, a definitive diagnosis is not needed before treatment can be initiated. Doxycycline is the first-line therapy for all rickettsioses. Adults are advised to take doxycycline 200 mg orally once, followed by 100 mg twice daily until the patient improves, has been afebrile for 48 hours, and has received treatment for at least 7 days.7 Oral chloramphenicol is considered a second-line treatment; however it is not available in the United States and is associated with adverse hematologic effects.7

More than half of people living with HIV have coronary plaque
More than half of people living with HIV and suppressed viral loads nonetheless had imaging-confirmed coronary artery disease – and despite longtime use of HIV drugs that have been associated with cardiovascular trouble, none of those drugs were implicated in disease risk in this study.
“Traditional risk factors and duration of HIV infection were associated with severe coronary artery disease,” said Andreas Knudsen, MD, PhD, an infectious disease provider at Copenhagen University Hospital, Hvidovre, Denmark, during his presentation at the 18th European AIDS Conference. “When we adjusted for time since diagnosis of HIV, none of the drugs remained associated with the severity of coronary artery disease.”
Notably, that included abacavir, which was found in another EACS presentation and in past research to be associated with increased rates of heart attacks. Abacavir is sold individually as a generic as well as a component of Epzicom (abacavir/lamivudine) and the single-drug regimen Triumeq (dolutegravir/abacavir/lamivudine).
The Copenhagen Comorbidity in HIV Infection (COCOMO) study enrolled 1,099 people living with HIV in the Danish capital beginning in 2015, and 705 of them had angiographies via CT available to include in the results. The participants were almost all male (89%), at a healthy weight (BMI of 25), and 96% had undetectable viral loads.
Large minorities of participants also had traditional risk factors for coronary artery disease. More than one in four smoked, one in five had high cholesterol, and 42% had high blood pressure. In addition, many had used drugs that have been associated with cardiovascular trouble, including abacavir, which 26% of participants had used; indinavir, used by 17% of participants; zidovudine/AZT, used by 47%; and didanosine, which 14% used. (While abacavir is still in use, the other three drugs are considered legacy drugs and are not in current use.)
In addition, nearly one in three (29%) were currently using a protease inhibitor, which has been associated with heart failure.
When the investigators looked at participants’ CTs, they found that, by the Coronary Artery Disease-Reporting and Data Systems (CAD-RAMS) scoring system, close to half (46%) had clear arteries with no signs of coronary artery disease. But that also meant that 54% had some blockage or stiffening of the arteries. The good news is that 27% of those people had minimal or mild coronary artery disease.
But a full 17% had confirmed obstructive coronary artery disease, and another 1 in 10 participants had the highest level of blockages. When they broke the data down by traditional and HIV medication–related risk factors for coronary artery disease, they found something interesting. Although obesity was associated with the presence of atherosclerosis, it wasn’t associated with severe disease. But diabetes was the reverse of that: It wasn’t associated with the presence of the disease, but it was associated with more severe disease.
And when they looked at abacavir, they found no relationship between the drug and atherosclerosis. “Abacavir was not associated with the presence of atherosclerosis and was also not associated with severity of disease,” said Dr. Knudsen.
Although past use of AZT, indinavir, and didanosine were associated with severity of atherosclerosis, that association went away when Dr. Knudsen and team adjusted the findings for time since diagnosis. What was associated atherosclerosis was length of time living with HIV itself. For every 5 years a person lived with HIV, the study found the risk of having any atherosclerosis increased 20% and severity increased 23%. In addition, being a man was associated with a nearly 2.5-times increased risk of having any atherosclerosis and a 96% increased chance of having more severe atherosclerosis. Having diabetes was associated with a nearly threefold increased risk of atherosclerosis, as was every additional decade of life for a person who was living with HIV.
The findings confirm the baseline data of the REPRIEVE trial, which recently released data showing similarly high rates of atherosclerotic plaque in people living with HIV who didn’t register as “at risk” for cardiovascular disease using traditional scoring methods.
“It’s important in that it’s a huge study that’s confirmatory [of] what we know, which is that there are high levels of subclinical coronary artery disease in people living with HIV,” said Steven Grinspoon, MD, professor at Harvard Medical School in Boston, Massachusetts, and principal investigator of REPRIEVE.
As for the lack of association between abacavir and cardiovascular risk, he said he’s taking the findings with a grain of salt.
“It’s hard to make a lot out of that,” he said. “It’s hard to know in a cross-sectional study. People put people on different things.”
In Spain, where Jose Ignacio Bernardino, MD, treats people living with HIV at La Paz University Hospital in Madrid, abacavir is mostly a moot point, as clinicians have long since moved away from maintaining people living with HIV on any abacavir-containing regimens. What’s more important in the study, he told this news organization, is that “worrisome” high level of risk. REPRIEVE will test whether statins can reduce heart disease events in people living with HIV. But in the meantime, he said the take-away for clinicians from the study is the primary importance of traditional cardiovascular risk factors.
“We have to acknowledge that the major cardiovascular risk factor is age,” he said. “When patients are approaching their 50s, I usually try to stress a lot about cardiovascular risk factors in general. I stress healthy lifestyle – get physical exercise, hypertension, glucose, lipids – in every single patient.”
Dr. Knudsen and Dr. Bernardino have disclosed no relevant financial relationships. Dr. Grinspoon reports receiving personal and consulting fees from Theratechnologies and ViiV Healthcare.

Although obesity was associated with the presence of atherosclerosis, it wasn’t associated with severe disease. But diabetes was the reverse of that: It wasn’t associated with the presence of the disease, but it was associated with more severe disease.
And when they looked at abacavir, they found no relationship between the drug and atherosclerosis. “Abacavir was not associated with the presence of atherosclerosis and was also not associated with severity of disease,” said Dr. Knudsen.
Although past use of AZT, indinavir, and didanosine were associated with severity of atherosclerosis, that association went away when Dr. Knudsen and team adjusted the findings for time since diagnosis. What was associated atherosclerosis was length of time living with HIV itself. For every 5 years a person lived with HIV, the study found the risk of having any atherosclerosis increased 20% and severity increased 23%. In addition, being a man was associated with a nearly 2.5-times increased risk of having any atherosclerosis and a 96% increased chance of having more severe atherosclerosis. Having diabetes was associated with a nearly threefold increased risk of atherosclerosis, as was every additional decade of life for a person who was living with HIV.
The findings confirm the baseline data of the REPRIEVE trial, which recently released data showing similarly high rates of atherosclerotic plaque in people living with HIV who didn’t register as “at risk” for cardiovascular disease using traditional scoring methods.
“It’s important in that it’s a huge study that’s confirmatory [of] what we know, which is that there are high levels of subclinical coronary artery disease in people living with HIV,” said Steven Grinspoon, MD, professor at Harvard Medical School in Boston, Massachusetts, and principal investigator of REPRIEVE.
As for the lack of association between abacavir and cardiovascular risk, he said he’s taking the findings with a grain of salt.
“It’s hard to make a lot out of that,” he said. “It’s hard to know in a cross-sectional study. People put people on different things.”
In Spain, where Jose Ignacio Bernardino, MD, treats people living with HIV at La Paz University Hospital in Madrid, abacavir is mostly a moot point, as clinicians have long since moved away from maintaining people living with HIV on any abacavir-containing regimens. What’s more important in the study, he told this news organization, is that “worrisome” high level of risk. REPRIEVE will test whether statins can reduce heart disease events in people living with HIV. But in the meantime, he said the take-away for clinicians from the study is the primary importance of traditional cardiovascular risk factors.
“We have to acknowledge that the major cardiovascular risk factor is age,” he said. “When patients are approaching their 50s, I usually try to stress a lot about cardiovascular risk factors in general. I stress healthy lifestyle – get physical exercise, hypertension, glucose, lipids – in every single patient.”
Dr. Knudsen and Dr. Bernardino have disclosed no relevant financial relationships. Dr. Grinspoon reports receiving personal and consulting fees from Theratechnologies and ViiV Healthcare.

Expected spike in acute flaccid myelitis did not occur in 2020
suggested researchers at the Centers for Disease Control and Prevention.
Acute flaccid myelitis (AFM) is an uncommon but serious complication of some viral infections, including West Nile virus and nonpolio enteroviruses. It is “characterized by sudden onset of limb weakness and lesions in the gray matter of the spinal cord,” they said, and more than 90% of cases occur in young children.
Cases of AFM, which can lead to respiratory insufficiency and permanent paralysis, spiked during the late summer and early fall in 2014, 2016, and 2018 and were expected to do so again in 2020, Sarah Kidd, MD, and associates at the division of viral diseases at the CDC’s National Center for Immunization and Respiratory Diseases, Atlanta, said in the Morbidity and Mortality Weekly Report.
Monthly peaks in those previous years – each occurring in September – reached 51 cases in 2014, 43 cases in 2016, and 88 cases in 2018, but in 2020 there was only 1 case reported in September, with a high of 4 coming in May, CDC data show. The total number of cases for 2020 (32) was, in fact, lower than in 2019, when 47 were reported.
The investigators’ main objective was to see if there were any differences between the 2018 and 2019-2020 cases. Reports from state health departments to the CDC showed that, in 2019-2020, “patients were older; more likely to have lower limb involvement; and less likely to have upper limb involvement, prodromal illness, [cerebrospinal fluid] pleocytosis, or specimens that tested positive for EV [enterovirus]-D68” than patients from 2018, Dr. Kidd and associates said.
Mask wearing and reduced in-school attendance may have decreased circulation of EV-D68 – the enterovirus type most often detected in the stool and respiratory specimens of AFM patients – as was seen with other respiratory viruses, such as influenza and respiratory syncytial virus, in 2020. Previous studies have suggested that EV-D68 drives the increases in cases during peak years, the researchers noted.
The absence of such an increase “in 2020 reflects a deviation from the previously observed biennial pattern, and it is unclear when the next increase in AFM should be expected. Clinicians should continue to maintain vigilance and suspect AFM in any child with acute flaccid limb weakness, particularly in the setting of recent febrile or respiratory illness,” they wrote.

Does zinc really help treat colds?
A new study published in BMJ Open adds to the evidence that zinc is effective against viral respiratory infections, such as colds.
Jennifer Hunter, PhD, BMed, of Western Sydney University’s NICM Health Research Institute, New South Wales, Australia, and colleagues conducted a meta-analysis of 28 randomized controlled trials (RCTs). They searched 17 English and Chinese databases to identify the trials and then used the Cochrane rapid review technique for the analysis.
The trials included 5,446 adults who had received zinc in a variety of formulations and routes — oral, sublingual, and nasal spray. The researchers separately analyzed whether zinc prevented or treated respiratory tract infections (RTIs)
Oral or intranasal zinc prevented five RTIs per 100 person-months (95% CI, 1 – 8; numbers needed to treat, 20). There was a 32% lower relative risk (RR) of developing mild to moderate symptoms consistent with a viral RTI.
Use of zinc was also associated with an 87% lower risk of developing moderately severe symptoms (incidence rate ratio, 0.13; 95% CI, 0.04 – 0.38) and a 28% lower risk of developing milder symptoms. The largest reductions in RR were for moderately severe symptoms consistent with an influenza-like illness.
Symptoms resolved 2 days earlier with sublingual or intranasal zinc compared with placebo (95% CI, 0.61 – 3.50; very low-certainty quality of evidence). There were clinically significant reductions in day 3 symptom severity scores (mean difference, -1.20 points; 95% CI, -0.66 to -1.74; low-certainty quality of evidence) but not in overall symptom severity. Participants who used sublingual or topical nasal zinc early in the course of illness were 1.8 times more likely to recover before those who used a placebo.
However, the investigators found no benefit of zinc when patients were inoculated with rhinovirus; there was no reduction in the risk of developing a cold. Asked about this disparity, Dr. Hunter said, “It might well be that when inoculating people to make sure they get infected, you give them a really high dose of the virus. [This] doesn’t really mimic what happens in the real world.”
On the downside of supplemental zinc, there were more side effects among those who used zinc, including nausea or gastrointestinal discomfort, mouth irritation, or soreness from sublingual lozenges (RR, 1.41; 95% CI, 1.17 – 1.69; number needed to harm, 7; moderate-certainty quality of evidence). The risk for a serious adverse event, such as loss of smell or copper deficiency, was low. Although not found in these studies, postmarketing studies have found that there is a risk for severe and in some cases permanent loss of smell associated with the use of nasal gels or sprays containing zinc. Three such products were recalled from the market.
The trial could not provide answers about the comparative efficacy of different types of zinc formulations, nor could the investigators recommend specific doses. The trial was not designed to assess zinc for the prevention or treatment of COVID-19.
Asked for independent comment, pediatrician Aamer Imdad, MBBS, assistant professor at the State University of New York Upstate Medical University, Syracuse, told this news organization, “It’s a very comprehensive review for zinc-related studies in adults” but was challenging because of the “significant clinical heterogeneity in the population.”
Dr. Imdad explained that zinc has “absolutely” been shown to be effective for children with diarrhea. The World Health Organization has recommended it since 2004. “The way it works in diarrhea is that it helps with the regeneration of the epithelium.... It also improves the immunity itself, especially the cell-mediated immunity.” He raised the question of whether it might work similarly in the respiratory tract. Dr. Imdad has a long-standing interest in the use of zinc for pediatric infections. Regarding this study, he concluded, “I think we still need to know the nuts and bolts of this intervention before we can recommend it more specifically.”
Dr. Hunter said, “We don’t have any high-quality studies that have evaluated zinc orally as treatment once you’re actually infected and have symptoms of the cold or influenza, or COVID.”
Asked about zinc’s possible role, Dr. Hunter said, “So I do think it gives us a viable alternative. More people are going, ‘What can I do?’ And you know as well as I do people come to you, and [they say], ‘Well, just give me something. Even if it’s a day or a little bit of symptom relief, anything to make me feel better that isn’t going to hurt me and doesn’t have any major risks.’ So I think in the short term, clinicians and consumers can consider trying it.”
Dr. Hunter was not keen on giving zinc to family members after they develop an RTI: “Consider it. But I don’t think we have enough evidence to say definitely yes.” But she does see a potential role for “people who are at risk of suboptimal zinc absorption, like people who are taking a variety of pharmaceuticals [notably proton pump inhibitors] that block or reduce the absorption of zinc, people with a whole lot of the chronic diseases that we know are associated with an increased risk of worse outcomes from respiratory viral infections, and older adults. Yes, I think [for] those high-risk groups, you could consider using zinc, either in a moderate dose longer term or in a higher dose for very short bursts of, like, 1 to 2 weeks.”
Dr. Hunter concluded, “Up until now, we all commonly thought that zinc’s role was only for people who were zinc deficient, and now we’ve got some signals pointing towards its potential role as an anti-infective and anti-inflammatory agent in people who don’t have zinc deficiency.”
But both Dr. Hunter and Dr. Imdad emphasized that zinc is not a game changer. There is a hint that it produces a small benefit in prevention and may slightly shorten the duration of RTIs. More research is needed.
Dr. Hunter has received payment for providing expert advice about traditional, complementary, and integrative medicine, including nutraceuticals, to industry, government bodies, and nongovernmental organizations and has spoken at workshops, seminars, and conferences for which registration, travel, and/or accommodation has been paid for by the organizers. Dr. Imdad has disclosed no relevant financial relationships.
