Survey: Most military family physicians wary of transgender treatments
The U.S. military now allows transgender people to serve openly, and all medical personnel are supposed to be trained in their treatment – including care related to gender transition – by June 2017.
But a new survey of 204 family physicians who work for the military shows that most aren’t willing to prescribe cross-hormone treatment to eligible adult transgender patients.
In addition, “we found that most military clinicians did not receive any formal training on transgender care during their medical education, most had not treated a patient with gender dysphoria, and most had not received sufficient training to prescribe cross-hormone therapy,” said Natasha A. Schvey, PhD, an assistant professor with the medical and clinical psychology department at the Uniformed Services University of the Health Sciences, Bethesda, Md., and lead author of a new study that summarizes the survey findings.
An estimated 12,800 transgender people serve in the U.S. military, and researchers believe that they make up a larger proportion of the military population than in the general population.
In October 2016, the Department of Defense ended its ban on service by transgender troops. A policy statement says: “Service members with a diagnosis from a military medical provider indicating that gender transition is medically necessary will be provided medical care and treatment for the diagnosed medical condition, in the same manner as other medical care and treatment.”
For the new study, Dr. Schvey and her associates surveyed 204 of the approximately 1,700 family physicians who serve the military (JAMA Intern Med. 2017 Mar 13. doi: 10.1001/jamainternmed.2017.0136). The survey respondents had all attended an annual meeting in March 2016.
Most respondents were male (62.8%) and white (85.5%); 21.7% were residents. The highest number of respondents (42.6%) worked for the U.S. Air Force.
Almost three-quarters of the respondents said that they had received no training or medical education in gender dysphoria, and 62.7% said they had never treated a transgender patient as a physician.
Just under half (47.1%) of respondents – 82 – said they would prescribe cross-hormone therapy to eligible adult patients, but only one would do so independently. The others would only do so with additional education (7.5% of all responding physicians), the help of an experienced clinician (17.2%), or both (21.8%).
The other 52.9% said they wouldn’t prescribe the hormone therapy. Eight percent of all responding physicians blamed ethical concerns, 19.5% pointed to lack of comfort, and 25.3% mentioned both, the investigators reported.
Why are so many physicians so uncomfortable?
Dr. Schvey said the survey design doesn’t allow for speculation about what the ethical concerns might be, but “the data did indicate that hours of training on transgender care were directly associated with the likelihood of prescribing cross-hormone therapy. Therefore, some of the lack of comfort may be due to lack of experience and adequate training.”
Although family physicians are generally used to treating patients with hormones for contraception and to treat perimenopausal symptoms and hypogonadism, many don’t know about dosing regimens and other information regarding their use in transgender patients, study coauthor David A. Klein, MD, assistant professor of family medicine and pediatrics at the Uniformed Services University of the Health Sciences, said in an interview. And, he noted, “some are unaware that provision of cross-hormone therapy is within their scope of care.”
Going forward, “given that greater education in transgender care is associated with increased competency,” Dr. Schvey said in an interview, “it will be important to assess the training of military physicians to ensure skill and sensitivity in treating patients who identify as transgender.”
The study had no specific funding, and the authors reported no relevant conflicts of interest.
I first learned the term transsexual from a 1972 publication by the American Medical Association titled “Human Sexuality.” I found the textbook on my father’s bookshelf as a 10-year-old and for the first time found a word to describe my inner world.
Up until 2016, transgender individuals in the military were not given appropriate medical or psychological assistance. They were forced to seek help in secret, outside the military health care system, or to await discharge proceedings.
Although the situation has improved markedly, there is still a long way to go. We need better protocols for individuals who wish to transition while active duty, for retirees, and their family members. We need to aid them in preserving their fertility, and we need to foster an environment of openness where no soldier feels like he or she is isolated from fellow service members owing to gender identity.
Although I completed my medical training as a male, today I serve as a female physician in every respect within the Department of Defense. Last month, I graduated the Army Medical Department’s Advanced Course with honors, and now I look forward to the second half of my military career being treated like any other capable military physician. My hope is that over time all clinicians gain comfort and skill in treating transgender persons.

AKI seen in 64% of children hospitalized with diabetic ketoacidosis
A high proportion of children with type 1 diabetes who are hospitalized for diabetic ketoacidosis (DKA) develop acute kidney injury (AKI), according to results from a study.
Researchers reviewing records from a Canadian hospital found that in a cohort of 165 children hospitalized for DKA during a 5-year period (2008-2013), 64% developed the complication. Severe forms of AKI (stage 2 or 3) were common, representing 45% and 20%, respectively, of children with AKI. Two patients in the cohort required dialysis.
“We hypothesized that, because DKA is associated with both volume depletion and conservative fluid administration upon presentation, these children are potentially at high risk for AKI, above the level of risk expected by the rare reported cases in the literature,” Dr. Hursh and his colleagues wrote (JAMA Pediatr. 2017 Mar 13. doi: 10.1001/jamapediatrics.2017.0020).
The investigators found that lower serum bicarbonate levels and elevated heart rates were indeed associated with increased risk of severe AKI. Serum bicarbonate level of less than 10 mEq/L was associated with a fivefold increase in the odds of severe (stage 2 or 3) AKI (adjusted odds ratio, 5.22; 95% confidence interval, 1.35-20.22). Each increase of 5 bpm in initial heart rate was associated with a 22% increase in the odds of severe AKI (aOR, 1.22; 95% CI, 1.07-1.39).
Dr. Hursh and his colleagues defined AKI using serum creatinine values. As baseline values prior to hospital admission were not available, the researchers used estimated normal value ranges from published studies, choosing a glomerular filtration rate of 120 mL/min per 1.73 m2 as a standard baseline value. Urine output was not used as a measure because of inconsistent records.
Of particular concern was that more than 40% of patients with AKI “did not have documented resolution of AKI prior to discharge or arrangements for follow-up in the nephrology clinic. Of note, the final AKI stage was severe for 50% of these children,” the researchers wrote in their analysis.
The findings suggest that clinicians “should consider AKI as a frequent complication that accompanies pediatric DKA and should be especially alert to its presence in severe presentations of DKA,” they said. AKI is underrecognized “both because of a lack of awareness of AKI as a complication of DKA and because the serum creatinine level in pediatric patients must be interpreted in the context of the child’s age and height. It is crucial to develop or have in place systems that identify and monitor abnormal markers of renal function in this population.”
The researchers acknowledged as limitations of their study its retrospective design, the absence of baseline serum creatinine values, and the lack of urine output data for use in AKI severity grading. And prospective longitudinal studies, they wrote, “are needed to assess the effect of these AKI episodes on the trajectory of renal disease in children with diabetes.”
The researchers reported no outside funding or relevant financial disclosures.
With the lack of targeted therapies to prevent AKI or decrease its associated consequences, supportive care is the mainstay of treatment and focuses on fluid and electrolyte management, nutrition, prevention of further injury through close attention to medication dosing, and, when needed, renal replacement therapy. At first glance, these findings may not appear to be overly surprising or significant; children with volume depletion have decreased renal blood flow, leading to AKI, which corrects with fluid administration. However, the authors appropriately suggest that this issue is not a simple one and that fluid management should be carefully considered in these patients. Because of severe hyperglycemia and derangements in serum sodium concentration, children with DKA are at risk of potentially catastrophic cerebral edema, leading to recommendations for cautious administration of fluids in this high-risk population.
These findings may lead clinicians and investigators to question established practices related to aggressive fluid administration in the sickest children. While awaiting more research to determine the sweet spot for fluid management in children with AKI, it seems reasonable to give fluids to patients with AKI secondary to volume depletion while quickly shifting to more restrictive strategies in those who do not respond to volume and have decreasing urine output. This may be especially important for children with DKA, as conservative fluid management may decrease central nervous system complications.
We commend the authors for exploring AKI in a novel pediatric population, expanding our knowledge on whom kidney function should be more diligently examined, providing insights on relevant fluid strategies, and increasing awareness for a group of patients who may benefit from closer long-term nephrology follow-up.

Replacement factors, bypassing agents safely manage fitusiran bleed events
Fitusiran appears to promote hemostasis and reduce the frequency of bleeding in patients with hemophilia. In a phase I trial of the investigational agent, breakthrough bleeds were treated effectively and safely with replacement factor or bypassing agent.
Bleed events were rare among patients achieving target antithrombin lowering of greater than 75% on fitusiran. Those that did occur were treated with factor concentrates, including recombinant Factor VIII or recombinant Factor IX, or with bypassing agents, including recombinant Factor VIIa or activated prothrombin complex–concentrates, Savita Rangarajan, MD, reported at the annual meeting of the European Association for Haemophilia and Allied Disorders.
The study included 41 patients with hemophilia A or B – 25 patients with inhibitors and 16 without inhibitors – who received either 50 mg or 80 mg of fitusiran. Early multiple ascending dose–cohorts received weekly subcutaneous dosing, and later cohorts received monthly dosing. All patients tolerated treatment well, with no serious adverse events related to the study drug. No thromboembolic events occurred, and the majority of adverse events were mild or moderate in severity, she noted.
Among patients with inhibitors, eight bleeds occurred in five patients with hemophilia A who were treated with Factor VIII, and three bleeds occurred in two patients with hemophilia B who were treated with Factor IX. Among those without inhibitors, six bleeds occurred in three patients treated with activated prothrombin complex–concentrates, and four occurred in three patients treated with recombinant Factor VIIa, said Dr. Rangarajan of Hampshire Hospitals NHS Foundation Trust, Basingstoke, England.
The ranges of factor replacement used per injection were 7-32 IU/kg of Factor VIII and 7-43 IU/kg of Factor IX.
The ranges of bypassing agents used per injection were 14-75 U/kg of activated prothrombin complex–concentrates (mean, 2.2 administrations per bleed) and 93-133 μg/kg of recombinant Factor VIIa (mean, 1.5 administrations per bleed), she said.
Doses of the factor concentrates and bypassing agents used were at or below those recommended by the World Federation of Hemophilia.
This phase I study of fitusiran, which targets and lowers antithrombin to improve thrombin generation and promote hemostasis in patients with hemophilia, is being conducted in four parts: Part A with healthy volunteers, parts B and C with patients with moderate to severe hemophilia A or B, and part D with patients with hemophilia A or B with inhibitors.
Findings from the current exploratory analysis of the data are encouraging as they demonstrate good treatment effect in the absence of identified safety concerns, Dr. Rangarajan said, noting that fitusiran should advance to pivotal studies in 2017 and that data on bleed management from a phase I and phase II open label extension will guide protocol on bleed management in phase III.

Fitusiran appears to promote hemostasis and reduce the frequency of bleeding in patients with hemophilia. In a phase I trial of the investigational agent, breakthrough bleeds were treated effectively and safely with replacement factor or bypassing agent.
Bleed events were rare among patients achieving target antithrombin lowering of greater than 75% on fitusiran. Those that did occur were treated with factor concentrates, including recombinant Factor VIII or recombinant Factor IX, or with bypassing agents, including recombinant Factor VIIa or activated prothrombin complex–concentrates, Savita Rangarajan, MD, reported at the annual meeting of the European Association for Haemophilia and Allied Disorders.
The study included 41 patients with hemophilia A or B – 25 patients with inhibitors and 16 without inhibitors – who received either 50 mg or 80 mg of fitusiran. Early multiple ascending dose–cohorts received weekly subcutaneous dosing, and later cohorts received monthly dosing. All patients tolerated treatment well, with no serious adverse events related to the study drug. No thromboembolic events occurred, and the majority of adverse events were mild or moderate in severity, she noted.
Among patients with inhibitors, eight bleeds occurred in five patients with hemophilia A who were treated with Factor VIII, and three bleeds occurred in two patients with hemophilia B who were treated with Factor IX. Among those without inhibitors, six bleeds occurred in three patients treated with activated prothrombin complex–concentrates, and four occurred in three patients treated with recombinant Factor VIIa, said Dr. Rangarajan of Hampshire Hospitals NHS Foundation Trust, Basingstoke, England.

VIDEO: Rucaparib benefits HGOC with BRCA mutations
National Harbor, MD. – The PARP inhibitor rucaparib is safe and effective in patients with primary platinum-sensitive high-grade ovarian carcinoma who have germline or somatic BRCA mutations, according to integrated summary data from parts 1 and 2 of the phase II ARIEL2 study.
Prior analyses of ARIEL2 data included 493 patients with germline/somatic BRCA mutations and BRCA wild-type. The current analysis included the 41 patients from ARIEL2 part 1 and the 93 patients from ARIEL2 part 2 who had germline or somatic BRCA mutations, and overall response rates in these patients ranged from 52% to 86% depending on the number of prior therapies, Gottfried E. Konecny, MD, reported at the annual meeting of the Society of Gynecologic Oncology.
The highest overall response rates were seen in platinum-sensitive vs. platinum-resistant and platinum-refractory patients, said Dr. Konecny of the University of California, Los Angeles.
Median progression-free survival was 12.7 months in the platinum-sensitive patients vs. 7.3 and 5.0 months in platinum-resistant and platinum-refractory patients, respectively, he said.
Treatment was generally safe and well tolerated. The most common treatment-emergent adverse events were nausea, fatigue, vomiting, and anemia; the most common grade 3/4 events included anemia, increased ALT/AST, and fatigue.
Previous findings from ARIEL2 and other studies of rucaparib led to conditional approval of the drug (pending further confirmation of the data), first for patients with germline or somatic BRCA mutations who fail at least three prior lines of chemotherapy, then for those who fail two or more prior therapies.
In this video, Dr. Konecny discusses his findings and the next steps with respect to the study of rucaparib for high-grade ovarian carcinoma.
ARIEL2 was supported by Clovis Oncology. Dr. Konecny is on the speakers’ bureau for AstraZeneca and Clovis Oncology and has received research funding or honorarium from Amgen, Merck, and Novartis.

When a doctor becomes a patient
An individual’s identity is a learned response to social stimuli, modeling oneself to the expectations of others. Doctors are perceived to be benevolent, knowledgeable, and powerful in matters of life and death. However, a complex concept of reverse hierarchy and role disorientation can take place when a doctor becomes a patient. Because doctors dedicate much of their lives to ensuring the well-being of patients, they may have a skewed perception of their personal health risks and fail to acknowledge that they, too, can fall victim to illness.
‘Them, not me’
Studies have found that doctors often do not advocate the same treatments for themselves than they would for their patients:
- Although most doctors recommend annual check-ups for their patients, 70% of physicians do not get one themselves.1
- Doctors are more likely to recommend potentially life-saving treatment with severe side effects to their patients than for themselves.2
These studies highlight how objectivity may be absent when doctors make decisions about their own treatment, as well as the complexity associated with treating a doctor as a patient.
A doctor’s sense of identity often is strongest in a health care setting. However, becoming a patient precipitates a drastic change in authority, duty, privacy, and even attire. Earlier this year, a colleague was in the hospital for workup of a cluster of symptoms. On a personal level, she experienced a momentary loss of identity, increased anxiety, and loss of self-esteem, which reduced her ability to connect with those who, in her professional role as “doctor,” were her colleagues. Trust became a matter of contention, especially in the context of understanding the inner workings of the health care system—its limitations, risks, and the possibility of human error. Professionally, she thought some management procedures were objectionable, but quickly assumed the passive role to avoid being labeled as “difficult.”
My colleague relayed 2 interesting viewpoints. First, doctors’ detached communication style seemed to evaporate when she revealed that she also is a physician. Perhaps it was the feeling of pride or competition that comes with being responsible for a colleague’s welfare or the camaraderie that lessened the divide. Slowness to relay clinical information or disregard for transparency—sometimes seen in the inpatient setting—were not apparent during my colleague’s care. However, aspects considered trivial from a doctor’s point of view, such as pre-procedural fasting, lack of privacy, and room changes became acutely intrusive.
Second, my colleague observed that her treatment team was overly solicitous. They wanted her to be pain-free and organized “urgent” tests to minimize waiting time. She recognized that there was an overt obligation to procure excessive investigations and treatment compared with a usual patient, because there was wariness of her vigilance of when things go wrong or are overlooked.
This situation was a reminder that clinicians should be mindful of finding the middle ground between unnecessary treatment for a “doctor as patient” and uninformed treatment for a “standard patient.”
Seek to understand
Role reversal represents the fundamental skill of connecting with others through self-awareness, self-regulation, and empathy.3 Studies have found that doctors who have assumed the patient role show more empathy and possess better communication skills.4 The situation for the doctor who becomes a patient may be disconcerting, but the “do no harm” nature of medicine and the generally accepting demeanor of patients render the relationship between empathy and role reversal especially harmonious. Although it is comfortable and convenient to stay on one side of the relationship, grasping an emotional representation of the other side is essential. It is the process of overcoming egocentricity and perceiving the subjective experience of the other role that is rewarding. We all desire to be understood, but to be understood, we must first seek to understand.

VIDEO: No disease progression in endometrial cancer patients with isolated tumor cells
AT THE ANNUAL MEETING ON WOMEN’S CANCER
NATIONAL HARBOR, MD. – Patients with endometrial cancer and isolated tumor cells in sentinel lymph nodes had excellent short-term outcomes, even if they opted out of adjuvant chemotherapy or radiation therapy.
In a single-center prospective study, all 10 such patients remained alive and free of disease progression at 3 years, Marie Plante, MD, said in a video interview at the annual meeting of the Society of Gynecologic Oncology.
The finding suggests that isolated tumor cells in sentinel lymph nodes are not, by themselves, an indication for adjuvant therapy in women with endometrial cancer, said Dr. Plante of Laval University in Quebec City. The issue remains controversial, however, and merits larger cohort studies with longer-term follow-up, she acknowledged.
Ultrastaging of sentinel lymph node biopsies that are negative on hematoxylin and eosin staining has boosted the detection of low-volume metastases. In the case of endometrial cancer with isolated tumor cells, there is a dilemma about whether to recommend adjuvant therapy. Very few studies have examined this relatively rare patient subgroup.
This study included 519 patients undergoing hysterectomy, salpingo-oophorectomy, lymphadenectomy, and sentinel lymph node mapping for endometrial cancer. Pathologic ultrastaging identified 31 patients with isolated tumor cells (6%), of whom 11 received adjuvant chemotherapy, 14 received pelvic radiation therapy, and 10 received brachytherapy or observation only.
Only one patient with isolated tumor cells developed recurrent disease within 3 years. This patient had a 7-cm carcinosarcoma that recurred despite adjuvant chemotherapy and radiation therapy. There were no recurrences among patients with endometrioid histology, Dr. Plante noted.
Dr. Plante cited no funding sources and reported having no conflicts of interest.

VIDEO: Sexuality, fertility are focus of cancer education website
MIAMI BEACH – Often people living with cancer hesitate to ask their providers about sensitive and important issues surrounding sexuality and fertility. At the same time, some clinicians remain uncomfortable raising questions regarding sexual function or simply lack the time to appropriately address the issues during a patient encounter.
A new online resource aims to solve both problems simultaneously, giving both patients and providers the tools to meaningfully address sexuality and fertility issues, Leslie R. Schover, PhD, said in a video interview at the annual Miami Breast Cancer Conference, held by Physicians’ Education Resource.
The Will2love.com site features first-person patient account videos from women and men who faced similar concerns, said Dr. Schover, founder of the Will2Love digital health company based in Houston. In addition, vignettes with actors inform patients and also model how oncologists, oncology nurses, and other staff could effectively communicate with concerned patients. A professional portal offers online skills training for clinicians.

MIAMI BEACH – Often people living with cancer hesitate to ask their providers about sensitive and important issues surrounding sexuality and fertility. At the same time, some clinicians remain uncomfortable raising questions regarding sexual function or simply lack the time to appropriately address the issues during a patient encounter.
A new online resource aims to solve both problems simultaneously, giving both patients and providers the tools to meaningfully address sexuality and fertility issues, Leslie R. Schover, PhD, said in a video interview at the annual Miami Breast Cancer Conference, held by Physicians’ Education Resource.
The Will2love.com site features first-person patient account videos from women and men who faced similar concerns, said Dr. Schover, founder of the Will2Love digital health company based in Houston. In addition, vignettes with actors inform patients and also model how oncologists, oncology nurses, and other staff could effectively communicate with concerned patients.

U.S. chikungunya epidemic would likely put rheumatologists on front line
SNOWMASS, COLO. – The continental United States is vulnerable to an epidemic of chikungunya virus disease, an event which would have profound consequences for rheumatologists, Robert T. Schoen, MD, said at the Winter Rheumatology Symposium sponsored by the American College of Rheumatology.
“We certainly have all the factors in place where we could have a major epidemic of chikungunya, particularly in Florida, Texas, and neighboring states. As rheumatologists, I think we can own this infection if we want to because it causes an arthritis that is a true arthritis in a significant percentage of patients,” said Dr. Schoen, a rheumatologist at Yale University in New Haven, Conn.
“That’s a major impact when you think that these epidemics affect tens of thousands of individuals. If 25% of them develop long-term arthritis disability, that’s a whole new world for us,” the rheumatologist observed.
Chikungunya is a single-stranded RNA virus in the togaviridae family, which also contains rubella. The infection is transmitted by Aedes aegypti and A. albopictus, also known as the yellow fever and Asian tiger mosquitoes, respectively. Both mosquitoes are established inhabitants of much of the United States.
“This infection is a one-bite deal. These are very aggressive mosquitoes,” Dr. Schoen observed. “If you haven’t seen a case of chikungunya yet, you will soon,” he added.
In 2014, at the height of a massive Caribbean epidemic which included half a million cases in Puerto Rico, roughly 2,800 cases of chikungunya were imported into 46 U.S. states. In 2015, however, as the Caribbean epidemic waned and herd immunity developed, that figure fell to 653 imported cases. But the epidemic in India, which began in 2008, remains ongoing with no end in sight. Several of Dr. Schoen’s patients with chikungunya had recently returned from India when they first became ill.
“India provides an unlimited reservoir of immunologically naive patients to perpetuate the infection,” he observed.
Course of illness
The rate of asymptomatic infection has been variously estimated at 3%-25%. Symptomatic chikungunya is a biphasic illness. After a 2- to 6-day incubation period, patients develop rapid-onset fever with severe joint pain and muscle aches. Indeed, chikungunya means “bent over” in Makonde, an African Bantu language.
Roughly 60% of patients develop a rash during the acute febrile phase of the illness, which lasts about a week. The dermatitis is most often a maculopapular rash on the trunk which is “absolutely indistinguishable” from the rash caused by Zika virus infection, transmitted by the same vectors, Dr. Schoen noted.
During this acute phase, almost all patients develop a severe polyarthritis which can last for weeks or, less commonly, for months or years. This polyarthritis mimics seronegative rheumatoid arthritis. It is usually symmetric and often affects the hands, wrists, and feet.
The acute febrile phase is characterized by high levels of viremia, with up to 1 billion viral particles per milliliter of blood. During this period, definitive diagnosis of chikungunya can be made through reverse transcriptase–polymerase chain reaction testing or viral culture.
Typically, though, patients make their way to a rheumatologist only well after the viremic period is over. In that situation, the diagnostic mainstay is serologic testing. Antichikungunya virus Immunoglobulin M is detectable starting on about day 5 after symptom onset, and it persists for the next 1-3 months. Immunoglobulin G (IgG) antibodies become detectable in the same time frame and remain elevated for years.
Dr. Schoen highlighted a small but intriguing study from Singapore that suggests that the early appearance of chikungunya-specific neutralizing IgG3–antibodies may constitute a marker for favorable long-term prognosis. The observational study involved 30 patients hospitalized for severe acute chikungunya infection. The investigators classified them into two groups: 14 patients had low levels of acute viremia, a less severe acute illness, and late development of IgG3 antibodies; the other 16 had a high initial viral load, a more severe acute phase, and a rapid IgG3 and interleukin-6 response to infection.
The patients with a robust early IgG3 response cleared the virus faster and none of them developed chronic arthritis. In contrast, those without early, chikungunya-specific IgG3 had a high rate of persistent arthralgia (J Infect Dis. 2012 Apr 1;205[7]:1147-54).
Treatment
No evidence-based treatment for chikungunya exists. Treatment in the acute phase is primarily supportive care. Rheumatologists on the Caribbean island of Martinique have reported a favorable experience using methotrexate at doses up to 25 mg/week or with standard doses of anti–tumor necrosis factor agents in chikungunya patients with severe bilateral symmetric chronic inflammatory joint disease arising during the 2013-2015 epidemic. The treatment response and tolerability were comparable with the results typically obtained in rheumatoid arthritis patients, according to the rheumatologists (Arthritis Rheumatol. 2016 Nov;68[11]:2817-24).
Dr. Schoen found the report from Martinique to be reassuring. He too has resorted to familiar rheumatologic medications in his severely affected patients. Anecdotally, his greatest success involved a patient with a 5-year history of disabling chikungunya polyarthritis who showed marked improvement after several months on hydroxychloroquine.
The Martinique investigators also reported on 22 patients who developed chikungunya while on biologic agents for rheumatoid arthritis, Crohn’s disease, psoriatic arthritis, or systemic lupus erythematosus. The biologics weren’t protective against the viral disease in these patients. All 22 of them developed severe acute chikungunya polyarthritis with a mean swollen joint count of 9.6 (Joint Bone Spine. 2016 Mar;83[2]:245-6).
Infection during pregnancy
There is a legitimate concern about chikungunya infection occurring during pregnancy, but, based on the experiences documented on Reunion Island, the risk to the baby is confined to intrapartum exposure in a viremic mother.
Reunion Island is a French region in the Indian Ocean off the eastern coast of Africa. It has first-world medical care. Much of the best documented early work on chikungunya outbreaks grew out of the 2005-2006 epidemic there, which affected more than one-third of the island’s 800,000-plus residents.
In a prospective study of 7,504 deliveries on the island during a 22-month period, mother-to-child transmission of chikungunya occurred only in the context of intrapartum viremia, with 19 cases of vertical transmission occurring among 39 affected mothers who delivered at a median 38 weeks of gestation. Cesarean section had no protective effect. All 19 infected neonates were asymptomatic at birth, with median onset of pain, fever, and thrombocytopenia on day 4. Nine of the 19 infected neonates developed encephalopathy with pathologic MRI findings, including cerebral hemorrhage in two cases (PLoS Med. 2008 Mar 18;5[3]:e60).
The case fatality rate for chikungunya is low at 0.1%. Most deaths occur in young children or elderly individuals with major comorbid conditions. Despite this low mortality, interest in chikungunya vaccine development is being driven by the infection’s impact on tourism, its spread to temperate climates, the economic impact of the considerable time lost from work, and military need. A promising attenuated, virus-like, particle-based vaccine is currently in phase II testing in the Caribbean.
Dr. Schoen reported having no financial conflicts.
