Key clinical point: Adjuvant abemaciclib plus endocrine therapy (ET) reduced the risk for recurrence and demonstrated a favorable safety profile in patients with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2−) early breast cancer (BC) at a high risk for recurrence.

Major finding: Abemaciclib+ET helped sustain the invasive disease-free survival benefit compared with only ET even at 42 months of median follow-up (hazard ratio 0.664; nominal P < .0001). Although the frequency of grade ≥3 adverse events was higher with abemaciclib+ET (49.9%) vs  ET alone (16.9%), it was considered manageable and acceptable for patients with high-risk early BC.

Study details: Findings are from the phase 3, monarchE trial including 5637 patients with HR+/HER2−, node-positive, early BC who were randomly assigned to receive adjuvant ET with or without abemaciclib.

Disclosures: This study was funded by Eli Lilly. Five authors declared being employees and shareholders of Eli Lilly, and the other authors reported ties with several sources, including Eli Lilly.

Key clinical point: In patients with high-risk early breast cancer (BC), a dose-dense adjuvant chemotherapy improved disease-free survival (DFS), whereas the addition of fluorouracil to the chemotherapy regimen failed to demonstrate any survival benefits.

Major finding: After a median follow-up of 15.1 years, the median DFS was similar with and without the addition of fluorouracil to the combination therapy of epirubicin, cyclophosphamide, and paclitaxel (EC-P; log-rank P = .11) and was significantly improved in the dose-dense vs  standard interval group (hazard ratio 0.77; P = .0004). The most common grade 3-4 adverse events were neutropenia and alopecia.

Study details: Findings are end of study results from the GIM2 trial including 2091 patients with node-positive early BC who were randomly assigned to receive standard-interval EC-P, standard-interval fluorouracil+EC-P (FEC-P), dose-dense EC-P, or dose-dense FEC-P.

On a recent overnight shift, our ObGyn on-call team was urgently paged to the emergency room for a patient who was brought in hemorrhaging after having passed out mid-flight from Texas to Boston. She was 12-weeks pregnant. We rushed her to the operating room for surgical removal of the pregnancy by dilation and curettage to stop her bleeding. Landing in Massachusetts had saved her life.

The significance of this patient’s case was not lost on the multidisciplinary teams caring for her, as the—at the time—impending Roe v Wade decision weighed heavily on our minds. One of many, her story foreshadows the harrowing experiences that we anticipate in the coming months and highlights the danger that the Supreme Court has inflicted on pregnant people nationally.

The Supreme Court decision on Dobbs v Jackson condemns us as a nation in which abortion rights are no longer federally protected under Roe v Wade.¹ Twenty-six states have been poised to ban abortion, and in at least 12 states, abortion is now illegal.^2,3 Political decision making will soon deny pregnant people the right to bodily autonomy, and the United States will lag behind other nations in abortion access.⁴ As ObGyn resident physicians who practice in tertiary referral hospitals in Massachusetts, where the ROE Act protects abortion beyond 24 weeks’ gestational age, we affirm abortion as essential health care that saves lives.⁵

Collectively as physician residents, we have provided an abortion for the patient at 22 weeks with a desired pregnancy who would have otherwise died from high blood pressures, the patient who ended her pregnancy to expedite breast cancer treatment, and the 16-year-old who feared for her life after suffering an assault by her partner for disclosing her pregnancy. With the overturn of Roe v Wade, patients like these will suffer dramatically divergent fates as race, class, and, now more than ever, geography will impact who is able to access abortion care.

Ramifications of the overturn of Roe

History foreshadows the grim impact of repealing Roe. Ohio’s 2011 law that requires the use of the restrictive protocol approved by the US Food and Drug Administration for mifepristone administration deepened existing inequities in abortion access.⁶ Patients with private insurance, higher income, higher level of education, and those who were White were more likely to obtain abortion care.⁷ In Texas, after the implementation of SB8 and other restrictive laws, Hispanic women whose travel distance increased more than 100 miles had the greatest reduction in abortion rates.^8,9 A recent study regarding banning abortion in the United States estimated a 7% increase in pregnancy-related deaths in 1 year, with a 21% increase in subsequent years.¹⁰

Inequities in abortion access subsequently will disparately increase deaths of pregnant individuals in certain populations.^11,12 Communities with the highest rates of unintended pregnancy, medical comorbidities, and lack of access to abortion, as well as historically marginalized populations—including non-Hispanic Black people, LGBTQIA people, those with limited English proficiency, and undocumented persons—will experience the greatest increase in pregnancy-related deaths due to a total abortion ban.^13-15

The US maternal mortality rate is already the highest among developed nations, and it will only climb if ObGyns are not appropriately trained to operate within our full scope of practice and, thus, are unable to provide the highest quality of care.^16,17

Abortion is a medical treatment that requires resident training

Abortion care must be protected. Uterine evacuation by medical management, suction curettage, or dilation and evacuation is indicated for undesired pregnancy, regardless of reasoning or life circumstance. Pregnancy carries inherent risks that can at times be deadly.¹⁸ Abortion serves as first-line treatment for certain life-threatening pregnancy risks, including septic miscarriage, maternal hemorrhage, early-onset severe preeclampsia, and certain health conditions.¹⁹ Surgical skills and medical management of abortion are therefore fundamental components of ObGyn care and residency training.²⁰

In choosing to become ObGyns,and particularly in selecting our training program, the ability to provide safe abortion care was a calculated priority. A recent study on the implications of overturning Roe predicted that nearly half of ObGyn residents will likely or certainly lose access to in-state abortion training.²¹ As demonstrated already in states with restrictive abortion laws, we will lose an entire generation of medical professionals skilled in performing this lifesaving procedure.^9,22 While privileged patients may travel across state borders to access care, ObGyn and other medical trainees who are contract bound to residency programs do not have such flexibility to seek out abortion training. Although we hope the reversal of Roe will be fleeting, the consequences of this lost generation are irreparable.^23,24 For physicians like ourselves, who fortunately are trained in surgical abortions and safe management of medical terminations, the discrepancy between evidence-based guidelines and impending political restrictions is distressing. We are forced to imagine refusing patients necessary health care—or face incarceration to save their lives.

The idea of watching a patient die, whether by hemorrhage, sepsis, or suicide, while armed with the tools of safe abortion technique is horrific. As authors with roots in Texas, Michigan, and Georgia, where abortion has or will almost certainly become illegal now that Roe v Wade is overturned, this scene is personal. It affects our future patients, our families, our colleagues, and our ability to return to our home states to live and practice.

Political organizing is critical to protect and restore abortion rights and defend against conservative coercive politics.²⁵ Nearly half of pregnancies in the United States are unintended, and more than half of these end in abortion.^26,27 Threats to abortion access require action from every one of the 59% of Americans who believe abortion should remain legal.²⁸ This is especially important from a social and racial justice perspective as abortion bans will disproportionately affect marginalized groups and further exacerbate inequities in maternal mortality.¹³

Call to action

Now is the time for community action for reproductive justice and human rights. We urge everyone to donate to abortion funds, vote for leaders who support reproductive justice, and petition your state legislators to codify Roe into law. Now is the time to expand legislation to protect abortion providers and our patients. To ObGyns, family medicine physicians, internists, and other reproductive health clinicians, now is the time to maximize your abortion training. Now is the time to act; otherwise, pregnant individuals will die and future generations of physicians will not have the training to save their lives. ●

EXPERT COMMENTARY

Breast cancer is the most diagnosed cancer among US women after skin cancer.¹ As of the end of 2020, 7.8 million women were alive who were diagnosed with breast cancer in the past 5 years, making it the world’s most prevalent cancer. Given the wide reach of breast cancer and the increase in its distant stage by more than 4% per year in women of reproductive age (20–39 years), clinicians are urged to address fertility preservation due to reproductive compromise of gonadotoxic therapies and gonadectomy.² To predict the risk of infertility following chemotherapy, a Cyclophosphamide Equivalent Dose (CED) calculator can be used. A CED of 4,000 mg/m² has been associated with a significant risk of infertility.³

In 2012, the American Society for Reproductive Medicine removed the experimental label of oocyte cryopreservation then recently endorsed ovarian cryopreservation, thereby providing acceptable procedures for fertility preservation.⁴ Gonadotropin-releasing hormone agonist use during chemotherapy, which is used to protect the ovary in premenopausal women against the effects of chemotherapy, has been shown to have inconsistent findings and should not replace the established modalities of oocyte/embryo/ovarian tissue cryopreservation.^2,5

Details of the study

While studies have been reassuring that ovarian stimulation for fertility preservation in women with breast cancer does not worsen the prognosis, findings are limited by short-term follow-up.⁶

The recent study by Marklund and colleagues presented an analysis of breast cancer relapse and mortality following fertility preservation with and without hormonal stimulation. In their prospective cohort study of 425 Swedish women who underwent fertility preservation, the authors categorized patients into 2 groups: oocyte and embryo cryopreservation by ovarian hormonal stimulation and ovarian tissue cryopreservation without hormonal stimulation. The control group included 850 women with breast cancer who did not undergo fertility preservation. The cohort and the control groups were matched on age, calendar period of diagnosis, and region. Three Swedish registers for breast cancer were used to obtain the study cohort, and for each participant, 2 breast cancer patients who were unexposed to fertility preservation were used for comparison. The primary outcome was mortality while the secondary outcome was any event of death due to breast cancer or relapse.

Results. A total of 1,275 women were studied at the time of breast cancer diagnosis. After stratification, which included age, parity at diagnosis, tumor size, number of lymph node metastases, and estrogen receptor status, disease-specific mortality was similar in all categories of women, that is, hormonal fertility preservation, nonhormonal fertility preservation, and controls. In the subcohort of 723 women, the adjusted rate of relapse and disease-specific mortality remained the same among all groups.

Study strengths and limitations

This study prompts several areas of criticism. The follow-up of breast cancer patients was only 5 years, adding to the limitations of short-term monitoring seen in prior studies. The authors also considered a delay in pregnancy attempts following breast cancer treatment of hormonally sensitive cancers of 5 to 10 years. However, the long-term safety of pregnancy following breast cancer has shown a statistically significantly superior disease-free survival (DFS) in patients who became pregnant less than 2 years from diagnosis and no difference in those who became pregnant 2 or more years from diagnosis.⁷

Only 58 women in the nonhormonal fertility preservation group (ovarian tissue cryopreservation) were studied, which may limit an adequate evaluation although it is not expected to negatively impact breast cancer prognosis. Another area of potential bias was the use of only a subcohort to assess relapse-free survival as opposed to the entire cohort that was used to assess mortality.

Strengths of this study include obligatory reporting to the registry and equal access to anticancer treatment and fertility preservation in Sweden. Ovarian stimulating drugs were examined, as letrozole is often used in breast cancer patients to maintain lower estradiol levels due to aromatase inhibition. Nevertheless, this study did not demonstrate a difference in mortality with or without letrozole use. ●

Three Swedish registers for breast cancer were used to obtain the study cohort, and for each participant, 2 breast cancer patients who were unexposed to fertility preservation were used for comparison. The primary outcome was mortality while the secondary outcome was any event of death due to breast cancer or relapse.

Results. A total of 1,275 women were studied at the time of breast cancer diagnosis. After stratification, which included age, parity at diagnosis, tumor size, number of lymph node metastases, and estrogen receptor status, disease-specific mortality was similar in all categories of women, that is, hormonal fertility preservation, nonhormonal fertility preservation, and controls. In the subcohort of 723 women, the adjusted rate of relapse and disease-specific mortality remained the same among all groups.

Study strengths and limitations

This study prompts several areas of criticism. The follow-up of breast cancer patients was only 5 years, adding to the limitations of short-term monitoring seen in prior studies. The authors also considered a delay in pregnancy attempts following breast cancer treatment of hormonally sensitive cancers of 5 to 10 years. However, the long-term safety of pregnancy following breast cancer has shown a statistically significantly superior disease-free survival (DFS) in patients who became pregnant less than 2 years from diagnosis and no difference in those who became pregnant 2 or more years from diagnosis.⁷

Only 58 women in the nonhormonal fertility preservation group (ovarian tissue cryopreservation) were studied, which may limit an adequate evaluation although it is not expected to negatively impact breast cancer prognosis. Another area of potential bias was the use of only a subcohort to assess relapse-free survival as opposed to the entire cohort that was used to assess mortality.

Strengths of this study include obligatory reporting to the registry and equal access to anticancer treatment and fertility preservation in Sweden. Ovarian stimulating drugs were examined, as letrozole is often used in breast cancer patients to maintain lower estradiol levels due to aromatase inhibition. Nevertheless, this study did not demonstrate a difference in mortality with or without letrozole use. ●

EXPERT COMMENTARY

Breast cancer is the most diagnosed cancer among US women after skin cancer.¹ As of the end of 2020, 7.8 million women were alive who were diagnosed with breast cancer in the past 5 years, making it the world’s most prevalent cancer. Given the wide reach of breast cancer and the increase in its distant stage by more than 4% per year in women of reproductive age (20–39 years), clinicians are urged to address fertility preservation due to reproductive compromise of gonadotoxic therapies and gonadectomy.² To predict the risk of infertility following chemotherapy, a Cyclophosphamide Equivalent Dose (CED) calculator can be used. A CED of 4,000 mg/m² has been associated with a significant risk of infertility.³

In 2012, the American Society for Reproductive Medicine removed the experimental label of oocyte cryopreservation then recently endorsed ovarian cryopreservation, thereby providing acceptable procedures for fertility preservation.⁴ Gonadotropin-releasing hormone agonist use during chemotherapy, which is used to protect the ovary in premenopausal women against the effects of chemotherapy, has been shown to have inconsistent findings and should not replace the established modalities of oocyte/embryo/ovarian tissue cryopreservation.^2,5

Details of the study

While studies have been reassuring that ovarian stimulation for fertility preservation in women with breast cancer does not worsen the prognosis, findings are limited by short-term follow-up.⁶

The recent study by Marklund and colleagues presented an analysis of breast cancer relapse and mortality following fertility preservation with and without hormonal stimulation. In their prospective cohort study of 425 Swedish women who underwent fertility preservation, the authors categorized patients into 2 groups: oocyte and embryo cryopreservation by ovarian hormonal stimulation and ovarian tissue cryopreservation without hormonal stimulation. The control group included 850 women with breast cancer who did not undergo fertility preservation. The cohort and the control groups were matched on age, calendar period of diagnosis, and region. Three Swedish registers for breast cancer were used to obtain the study cohort, and for each participant, 2 breast cancer patients who were unexposed to fertility preservation were used for comparison.

In the subcohort of 723 women, the adjusted rate of relapse and disease-specific mortality remained the same among all groups.

A 35-year-old woman with a history of hypothyroidism and idiopathic small fiber autonomic and sensory neuropathy presented to the emergency department (ED) 48 hours after IV immunoglobulin (IG) infusion with a severe headache, nausea, neck stiffness, photophobia, and episodes of intense positional eye pressure. The patient reported previous episodes of headaches post-IVIG infusion but not nearly as severe. On ED arrival, the patient was afebrile with vital signs within normal limits. Initial laboratory results were notable for levels within reference range parameters: 5.9 × 10⁹/L white blood cell (WBC) count, 13.3 g/dL hemoglobin, 38.7% hematocrit, and 279 × 10⁹/L platelet count; there were no abnormal urinalysis findings, and she was negative for human chorionic gonadotropin.

Due to the patient’s symptoms concerning for an acute intracranial process, a brain computed tomography (CT) without contrast was ordered. The CT demonstrated no intracranial abnormalities, but the patient’s symptoms continued to worsen. The patient was started on IV fluids and 1 g IV acetaminophen and underwent a lumbar puncture (LP). Her opening pressure was elevated at 29 cm H₂O (reference range, 6-20 cm), and the fluid was notably clear. During the LP, 25 mL of cerebrospinal fluid (CSF) was collected for laboratory analysis to include a polymerase chain reaction (PCR) panel and cultures, and a closing pressure of 12 cm H₂O was recorded at the end of the procedure with the patient reporting some relief of pressure. The patient was admitted to the medicine ward for further workup and observations.The patient’s meningitis/encephalitis PCR panel detected no pathogens in the CSF, but her WBC count was 84 × 10⁹/L (reference range, 4-11) with 30 segmented neutrophils (reference range, 0-6) and red blood cell count of 24 (reference range, 0-1); her normal glucose at 60 mg/dL (reference range, 40-70) and protein of 33 mg/dL (reference range, 15-45) were within normal parameters. Brain magnetic resonance images with and without contrast was inconsistent with any acute intracranial pathology to include subarachnoid hemorrhage or central nervous system neoplasm (Figure 1). Bacterial and fungal cultures were negative.

Discussion

Aseptic meningitis presents with a typical clinical picture of meningitis to include headache, stiffened neck, and photophobia. In the event of negative CSF bacterial and fungal cultures and negative viral PCR, a diagnosis of aseptic meningitis is considered.¹ Though the differential for aseptic meningitis is broad, in the immunocompetent patient, the most common etiology of aseptic meningitis in the United States is by far viral, and specifically, enterovirus (50.9%). It is less commonly caused by herpes simplex virus (8.3%), varicella zoster virus, and finally, the mosquito-borne St. Louis encephalitis and West Nile viruses typically acquired in the summer or early fall months. Other infectious agents that can present with aseptic meningitis are spirochetes (Lyme disease and syphilis), tuberculous meningitis, fungal infections (cryptococcal meningitis), and other bacterial infections that have a negative culture. Once an infectious cause becomes low on the differential, the remaining 3.5% of cases can be attributed to a noninfectious aseptic etiology.² This includes neoplasia, autoimmune, auto-inflammatory, iatrogenic, and drug induced (the most common subtype of this category) as possible causes.

The patient’s history, physical examination, vital signs, imaging, and lumbar puncture findings were most concerning for drug-induced aseptic meningitis (DIAM) secondary to her recent IVIG infusion. An algorithm can be used to work through the diagnostic approach (Figure 2).^3,4

Conclusions

We encourage heightened clinical suspicion of DIAM in patients who have recently undergone IVIG infusion and present with meningeal signs (stiff neck, headache, photophobia, and ear/eye pressure) without any evidence of infection on physical examination or laboratory results. With such, we hope to improve clinician suspicion, detection, as well as patient education and outcomes in cases of DIAM.

Aerococcus urinae (A urinae), a gram-positive coccus readily mistaken for a Staphylococcus species, was first identified in 1992.^1-3 It now reportedly accounts for 0.2% to 0.8% of clinical urine isolates.^4-6 A urinae bacteriuria is typically asymptomatic and mainly occurs in women.^7-9 Symptomatic A urinae urinary tract infection (UTI) occurs predominantly in older men with underlying urologic abnormalities.^4-10 

Serious A urinae infections are rare. The first 2 reported cases involved men with A urinae endocarditis, one of whom died.^11,12 To date, only 8 cases of spondylodiscitis due to A urinae have been reported.^13-20 Optimal treatment for invasive A urinae infection is undefined; however, the reported cases were treated successfully with diverse antibiotic regimen combinations; all including a β-lactam and beginning with at least 2 weeks of IV antibiotics.^13-20 We describe a man with A urinae bacteremia and spondylodiscitis, presumably arising from a urinary source in the setting of bladder outlet obstruction, who was treated successfully.

Case Presentation

A 74-year-old man with morbid obesity, type 2 diabetes mellitus, stage 2 chronic kidney disease, and tobacco use presented to the emergency department after 2 weeks of progressive, nonradiating, midthoracic back pain, lower extremity weakness, gait imbalance, fatigue, anorexia, rigors, and subjective fevers. On presentation, he was afebrile and hemodynamically stable. A physical examination revealed point tenderness of the midthoracic vertebrae, nontender costovertebral angles, diffusely decreased strength, nonsustained clonus in both lower extremities, inguinal intertrigo, and a buried penis with purulent meatal discharge.

Laboratory results indicated a white blood cell (WBC) count of 13.5 K/μL (reference range, 4.0-11.0), absolute neutrophil count of 11.48 K/μL (reference range, 2.0-7.7), C-reactive protein (CRP) level of 225.3 mg/L (reference range, ≤ 5.0), erythrocyte sedimentation rate of 85 mm/h (reference range, 5-15), serum blood urea nitrogen of 76 mg/dL (reference range, 8-26), and serum creatinine (SCr) of 1.9 mg/dL (reference range, 1.1-1.4). A urinalysis showed positive leukocyte esterase, WBC clumps, and little bacteria. Abdominal/pelvic computed tomography showed spondylodiscitis-like changes at T7-T8, bilateral perinephric fat stranding, bladder distension, and bladder wall thickening.

The patient was presumed to have discitis secondary to a UTI, with possible pyelonephritis, and was given empiric vancomycin and ceftriaxone. Spinal magnetic resonance imaging with contrast supported spondylodiscitis at T7-T8, extending to T8-T9. Preliminary results from the admission blood and urine cultures showed gram-positive cocci in clusters, which were presumed initially to be Staphylococcus aureus (S aureus).

The final urine culture report listed multiple organisms, predominantly A urinae (Table 1);

On hospital day 6, the patient’s back pain had resolved, micturition was normal, appetite had normalized, and SCr was minimally above baseline (1.4 mg/dL). He insisted on completing antibiotic treatment at home and had no other medical indication for continued hospitalization. Thus, antibiotic therapy was changed to an all-oral regimen of amoxicillin 1 g 3 times daily for 10 days and levofloxacin 750 mg daily for 6 weeks, and the patient was discharged to home.

The patient returned 5 days postdischarge due to anuria. Investigation showed severe acute kidney injury (SCr, 6.8 mg/dL) and bladder outlet obstruction due to phimosis and urethral meatal stenosis. Urinalysis was unremarkable. His CRP had declined from 225 mg/L (initial admission) to 154 mg/L. A urinae culture and 2 sets of blood cultures were finalized as no growth. He was diagnosed with postrenal acute kidney injury and underwent meatal dilation and Foley catheterization but declined surgical correction. When seen in the clinic 2 months postantimicrobial therapy, the patient had normal micturition, no symptoms or signs of infection, and steadily down-trending inflammatory markers.

Discussion

A urinae, historically considered a rare pathogen, has been identified with increasing frequency in urine cultures due to improved microbiologic diagnostic techniques. However, there are only 8 reported cases of A urinae spondylodiscitis. Urinary pathology is an accepted risk factor for A urinae infections; consequently, we suspect that our patient’s urinary outflow obstruction and poor genitourinary hygiene were related to his invasive A urinae infection.^10,21,22 We surmise that he had a chronic urinary outflow obstruction contributing to his infection, as evidenced by imaging findings, while the phimosis and urethral meatal stenosis were most likely infectious sequelae considering his anuria and acute kidney injury 5 days postdischarge. Indeed, the correlation between A urinae and urinary tract pathology may justify an evaluation for urinary pathology in any man with A urinae infection, regardless of the presence of symptoms.

By contrast, the implications of A urinae bacteriuria remain unclear. From a public health perspective, A urinae bacteriuria is rare, but the infectious mechanism remains undetermined with a case report suggesting the possibility of sexual transmission.^4-6,23 In our case, the patient was not sexually active and had no clear origin of infection. Considering the potential severity of infection, more studies are needed to determine the infectious mechanism of A urinae.

In terms of infectious morbidity, the results seem to vary by sex. In a retrospective study of about 30,000 clinical urine samples, 62 (58 from women, 4 from men) yielded A urinae. The 62 corresponding patients lacked systemic infectious complications, leading the authors to conclude that A urinae is a relatively avirulent organism.²⁴ Although possibly true in women, we are wary of drawing conclusions, especially regarding men, from a study that included only 62 urine samples were A urinae–positive, with only 4 from men. More evidence is needed to define the prognostic implications of A urinae bacteriuria in men.

As illustrated by the present case and previous reports, severe A urinae infections can occur, and the contributory factors deserve consideration. In our patient, the actual mechanism for bacteremia remains unclear. The initial concern for acute pyelonephritis was prompted by a computed tomography finding of bilateral perinephric fat stranding. This finding was questioned because it is common in older patients without infection, hence, is highly nonspecific. A correlation with urinary outflow obstruction may be an important clue in cases like this one.^25,26

Furthermore, whether the urinary tract truly was the source of the patient’s bacteremia is clouded by the differing antimicrobial susceptibility patterns of the A urinae blood and urine isolates. The simplest explanation for this discordance may be that all the isolates shared a common initial origin but adapted to different environments in the host (perhaps over time) or laboratory, producing phenotypic variation. Alternatively, the infection could have been polyclonal from the onset, with sampling error leading to the differing detected susceptibility patterns, or the blood and urine isolates may have represented independent acquisition events, involving distinct A urinae strains. Unfortunately (from an academic perspective), given patient preferences and recommendations from the infectious disease consultant, no bone biopsy was done for histology and culture to confirm infection and to allow comparative strain identification if A urinae was isolated. 

Optimal treatment for A urinae spondylodiscitis has yet to be established. β-lactams have shown good clinical efficacy despite being bacteriostatic in vitro.²⁷ Early in vitro studies showed synergistic bactericidal synergistic activity with penicillin plus aminoglycoside combination therapies.^27-30 Cases of endocarditis have been successfully treated mainly with the combination of a β-lactam plus aminoglycoside combination therapy.^30,31 Previous cases of spondylodiscitis have been treated successfully with diverse antimicrobial agents, including clindamycin, β-lactams, cephalosporins, fluoroquinolones, and aminoglycosides.¹⁴

Our patient improved rapidly while receiving empiric therapy with vancomycin and ceftriaxone and tolerated a rapid transition to oral amoxicillin and levofloxacin. This is the shortest IV treatment course for A urinae spondylodiscitis reported to date. We suspect that such rapid IV-to-oral transitions will suffice in most stable patients with A urinae spondylodiscitis or other invasive A urinae infections in line with the results of the OVIVA and POET trials.^32,33

Conclusions

We believe A urinae UTI in the absence of obvious predisposing factors should prompt evaluation for urinary outflow obstruction. Despite improved laboratory diagnostic techniques, spondylodiscitis related to A urinae remains a rare entity and thus definitive treatment recommendations are difficult to make. However, we suspect that in many cases it is reasonable to extrapolate from the results of the POET and OVIVA trials and rapidly transition therapy of A urinae spondylodiscitis from IV to oral antibiotics. We suspect a review of the US Department of Veterans Affairs population might uncover a higher incidence of A urinae infection than previously estimated due to the population demographics and the epidemiology of A urinae.

The simplest explanation for this discordance may be that all the isolates shared a common initial origin but adapted to different environments in the host (perhaps over time) or laboratory, producing phenotypic variation. Alternatively, the infection could have been polyclonal from the onset, with sampling error leading to the differing detected susceptibility patterns, or the blood and urine isolates may have represented independent acquisition events, involving distinct A urinae strains. Unfortunately (from an academic perspective), given patient preferences and recommendations from the infectious disease consultant, no bone biopsy was done for histology and culture to confirm infection and to allow comparative strain identification if A urinae was isolated. 

Optimal treatment for A urinae spondylodiscitis has yet to be established. β-lactams have shown good clinical efficacy despite being bacteriostatic in vitro.²⁷ Early in vitro studies showed synergistic bactericidal synergistic activity with penicillin plus aminoglycoside combination therapies.^27-30 Cases of endocarditis have been successfully treated mainly with the combination of a β-lactam plus aminoglycoside combination therapy.^30,31 Previous cases of spondylodiscitis have been treated successfully with diverse antimicrobial agents, including clindamycin, β-lactams, cephalosporins, fluoroquinolones, and aminoglycosides.¹⁴

Our patient improved rapidly while receiving empiric therapy with vancomycin and ceftriaxone and tolerated a rapid transition to oral amoxicillin and levofloxacin. This is the shortest IV treatment course for A urinae spondylodiscitis reported to date. We suspect that such rapid IV-to-oral transitions will suffice in most stable patients with A urinae spondylodiscitis or other invasive A urinae infections in line with the results of the OVIVA and POET trials.^32,33

Conclusions

We believe A urinae UTI in the absence of obvious predisposing factors should prompt evaluation for urinary outflow obstruction. Despite improved laboratory diagnostic techniques, spondylodiscitis related to A urinae remains a rare entity and thus definitive treatment recommendations are difficult to make. However, we suspect that in many cases it is reasonable to extrapolate from the results of the POET and OVIVA trials and rapidly transition therapy of A urinae spondylodiscitis from IV to oral antibiotics. We suspect a review of the US Department of Veterans Affairs population might uncover a higher incidence of A urinae infection than previously estimated due to the population demographics and the epidemiology of A urinae.

Aerococcus urinae (A urinae), a gram-positive coccus readily mistaken for a Staphylococcus species, was first identified in 1992.^1-3 It now reportedly accounts for 0.2% to 0.8% of clinical urine isolates.^4-6 A urinae bacteriuria is typically asymptomatic and mainly occurs in women.^7-9 Symptomatic A urinae urinary tract infection (UTI) occurs predominantly in older men with underlying urologic abnormalities.^4-10 

Serious A urinae infections are rare. The first 2 reported cases involved men with A urinae endocarditis, one of whom died.^11,12 To date, only 8 cases of spondylodiscitis due to A urinae have been reported.^13-20 Optimal treatment for invasive A urinae infection is undefined; however, the reported cases were treated successfully with diverse antibiotic regimen combinations; all including a β-lactam and beginning with at least 2 weeks of IV antibiotics.^13-20 We describe a man with A urinae bacteremia and spondylodiscitis, presumably arising from a urinary source in the setting of bladder outlet obstruction, who was treated successfully.

Case Presentation

A 74-year-old man with morbid obesity, type 2 diabetes mellitus, stage 2 chronic kidney disease, and tobacco use presented to the emergency department after 2 weeks of progressive, nonradiating, midthoracic back pain, lower extremity weakness, gait imbalance, fatigue, anorexia, rigors, and subjective fevers. On presentation, he was afebrile and hemodynamically stable. A physical examination revealed point tenderness of the midthoracic vertebrae, nontender costovertebral angles, diffusely decreased strength, nonsustained clonus in both lower extremities, inguinal intertrigo, and a buried penis with purulent meatal discharge.

Laboratory results indicated a white blood cell (WBC) count of 13.5 K/μL (reference range, 4.0-11.0), absolute neutrophil count of 11.48 K/μL (reference range, 2.0-7.7), C-reactive protein (CRP) level of 225.3 mg/L (reference range, ≤ 5.0), erythrocyte sedimentation rate of 85 mm/h (reference range, 5-15), serum blood urea nitrogen of 76 mg/dL (reference range, 8-26), and serum creatinine (SCr) of 1.9 mg/dL (reference range, 1.1-1.4). A urinalysis showed positive leukocyte esterase, WBC clumps, and little bacteria. Abdominal/pelvic computed tomography showed spondylodiscitis-like changes at T7-T8, bilateral perinephric fat stranding, bladder distension, and bladder wall thickening.

The patient was presumed to have discitis secondary to a UTI, with possible pyelonephritis, and was given empiric vancomycin and ceftriaxone. Spinal magnetic resonance imaging with contrast supported spondylodiscitis at T7-T8, extending to T8-T9. Preliminary results from the admission blood and urine cultures showed gram-positive cocci in clusters, which were presumed initially to be Staphylococcus aureus (S aureus).

The final urine culture report listed multiple organisms, predominantly A urinae (Table 1);

On hospital day 6, the patient’s back pain had resolved, micturition was normal, appetite had normalized, and SCr was minimally above baseline (1.4 mg/dL). He insisted on completing antibiotic treatment at home and had no other medical indication for continued hospitalization. Thus, antibiotic therapy was changed to an all-oral regimen of amoxicillin 1 g 3 times daily for 10 days and levofloxacin 750 mg daily for 6 weeks, and the patient was discharged to home.

The patient returned 5 days postdischarge due to anuria. Investigation showed severe acute kidney injury (SCr, 6.8 mg/dL) and bladder outlet obstruction due to phimosis and urethral meatal stenosis. Urinalysis was unremarkable. His CRP had declined from 225 mg/L (initial admission) to 154 mg/L. A urinae culture and 2 sets of blood cultures were finalized as no growth. He was diagnosed with postrenal acute kidney injury and underwent meatal dilation and Foley catheterization but declined surgical correction. When seen in the clinic 2 months postantimicrobial therapy, the patient had normal micturition, no symptoms or signs of infection, and steadily down-trending inflammatory markers.

Discussion

A urinae, historically considered a rare pathogen, has been identified with increasing frequency in urine cultures due to improved microbiologic diagnostic techniques. However, there are only 8 reported cases of A urinae spondylodiscitis. Urinary pathology is an accepted risk factor for A urinae infections; consequently, we suspect that our patient’s urinary outflow obstruction and poor genitourinary hygiene were related to his invasive A urinae infection.^10,21,22 We surmise that he had a chronic urinary outflow obstruction contributing to his infection, as evidenced by imaging findings, while the phimosis and urethral meatal stenosis were most likely infectious sequelae considering his anuria and acute kidney injury 5 days postdischarge. Indeed, the correlation between A urinae and urinary tract pathology may justify an evaluation for urinary pathology in any man with A urinae infection, regardless of the presence of symptoms.

By contrast, the implications of A urinae bacteriuria remain unclear. From a public health perspective, A urinae bacteriuria is rare, but the infectious mechanism remains undetermined with a case report suggesting the possibility of sexual transmission.^4-6,23 In our case, the patient was not sexually active and had no clear origin of infection. Considering the potential severity of infection, more studies are needed to determine the infectious mechanism of A urinae.

In terms of infectious morbidity, the results seem to vary by sex. In a retrospective study of about 30,000 clinical urine samples, 62 (58 from women, 4 from men) yielded A urinae. The 62 corresponding patients lacked systemic infectious complications, leading the authors to conclude that A urinae is a relatively avirulent organism.²⁴ Although possibly true in women, we are wary of drawing conclusions, especially regarding men, from a study that included only 62 urine samples were A urinae–positive, with only 4 from men. More evidence is needed to define the prognostic implications of A urinae bacteriuria in men.

As illustrated by the present case and previous reports, severe A urinae infections can occur, and the contributory factors deserve consideration. In our patient, the actual mechanism for bacteremia remains unclear. The initial concern for acute pyelonephritis was prompted by a computed tomography finding of bilateral perinephric fat stranding. This finding was questioned because it is common in older patients without infection, hence, is highly nonspecific. A correlation with urinary outflow obstruction may be an important clue in cases like this one.^25,26

Furthermore, whether the urinary tract truly was the source of the patient’s bacteremia is clouded by the differing antimicrobial susceptibility patterns of the A urinae blood and urine isolates. The simplest explanation for this discordance may be that all the isolates shared a common initial origin but adapted to different environments in the host (perhaps over time) or laboratory, producing phenotypic variation. Alternatively, the infection could have been polyclonal from the onset, with sampling error leading to the differing detected susceptibility patterns, or the blood and urine isolates may have represented independent acquisition events, involving distinct A urinae strains. Unfortunately (from an academic perspective), given patient preferences and recommendations from the infectious disease consultant, no bone biopsy was done for histology and culture to confirm infection and to allow comparative strain identification if A urinae was isolated. 

Optimal treatment for A urinae spondylodiscitis has yet to be established. β-lactams have shown good clinical efficacy despite being bacteriostatic in vitro.²⁷ Early in vitro studies showed synergistic bactericidal synergistic activity with penicillin plus aminoglycoside combination therapies.^27-30 Cases of endocarditis have been successfully treated mainly with the combination of a β-lactam plus aminoglycoside combination therapy.^30,31 Previous cases of spondylodiscitis have been treated successfully with diverse antimicrobial agents, including clindamycin, β-lactams, cephalosporins, fluoroquinolones, and aminoglycosides.¹⁴

Our patient improved rapidly while receiving empiric therapy with vancomycin and ceftriaxone and tolerated a rapid transition to oral amoxicillin and levofloxacin. This is the shortest IV treatment course for A urinae spondylodiscitis reported to date. We suspect that such rapid IV-to-oral transitions will suffice in most stable patients with A urinae spondylodiscitis or other invasive A urinae infections in line with the results of the OVIVA and POET trials.^32,33

More than 280,000 women in the United States will be diagnosed with invasive breast cancer this year. For those with metastatic breast cancer with distant spread, the 5-year survival rate is approximately 28%. Whether advanced disease is discovered at initial diagnosis or in relapsed disease, it is imperative to understand the molecular characteristics of the metastatic tumor.  

Dr Susan Domchek, from the University of Pennsylvania, discusses the importance of retesting for estrogen receptor, progesterone receptor, and HER2/neu on a metastatic tumor focus in order to identify potential discordance between the primary cancer and metastatic disease. 

Additionally, Dr Domchek discusses the importance of molecular testing for targetable mutations, including P13K and germline BRCA1/2, for which approved therapies have shown survival benefit. 

The list of targetable mutations in breast cancer continues to expand. In the tumor-agnostic studies, pembrolizumab has shown survival benefit in tumors that have mismatch repair deficiency and microsatellite instability, and TRK inhibitors have shown efficacy in tumors positive for NTRK fusions. Numerous clinical trials are available looking at additional molecular-based therapies.

Sir Augustus d’Este (1794-1848) described the circumstances preceding his development of neurological symptoms as follows:¹ “I travelled from Ramsgate to the Highlands of Scotland for the purpose of passing some days with a Relation for whom I had the affection of a Son. On my arrival I found him dead. Shortly after the funeral I was obliged to have my letters read to me, and their answers written for me, as my eyes were so attacked that when fixed upon minute objects indistinctness of vision was the consequence: Soon after I went to Ireland, and without any thing having been done to my eyes, they completely recovered their strength and distinctness of vision…" He then described a clinical course of relapsing-remitting neurologic symptoms merging into a progressive stage of unrelenting illness, most fitting with what we know today as multiple sclerosis (MS).¹ Why did Sir Augustus d'Este connect the event of the unexpected death to the onset of a lifelong neurologic disease?

Jean-Martin Charcot first described MS in a way close to what we know it as today. Charcot considered stress a factor in MS. He linked grief, vexation, and adverse changes in social circumstances to the onset of MS at that time.² I, as a practicing MS specialist, am surprised neither by Sir Augustus d'Este's diary nor by Charcot's earlier assessments of MS triggers.³ As I write this narrative, I think of the many times I heard from people diagnosed with MS. "It happened to me because of stress" is a statement not estranged from my daily clinical practice

MS as a multifactorial disease

It is tempting to make a case for emotional stress as a cause of MS, but one must remember that MS is a very complex disease with unclear etiologies. MS, a treatable but not yet curable disease, is the interplay between the genetics of the host and numerous environmental factors that exploit a susceptible immune system leading to unrelenting immune dysregulation.⁴ Recent studies have brought some pieces of this intricate puzzle together. The role of Epstein-Barr virus (EBV) in the pathogenesis of MS is being dissected.⁵ The possible synergy between vitamin D deficiency, EBV, and certain genetic variations is being studied.⁶ The roles of smoking, environmental toxins, obesity, diet, Western lifestyle, and the gut microbiome are some of the top areas of clinical, translational, and basic research.^7-11 But what about emotional stress? Where does it fit, if anywhere, in the current research paradigm?

Emotional stress and MS—Causality or not?

In the scientific method, several criteria must be proven for an element to be suspected in the etiology of a disease.¹² First, the suspect element must be present before the disease starts—i.e., a temporal association. Second, there must be a plausible biological explanation of how the suspect element acts in the disease's causation. Third, other variables that could confound the picture must be controlled for or dismissed. It is clear that no single factor is the cause of MS. By now, MS is agreed upon as a disease caused by multiple factors, some of which remain to be unraveled.⁹ The term "cause" has been utilized more recently by many authors when referring to EBV in relation to MS development, reasoning that in one study, in a small number of individuals with MS, EBV infection preceded the MS clinical diagnosis.¹³ Thus, the temporal association was provided. But does MS start at the onset of clinical symptoms?

For Sir Augustus d'Este, the disease may have started years before he visited the Highlands of Scotland, but only at that visit did MS become clinically apparent. So, the emotional trauma may have acted as a "trigger" for an MS flare-up rather than being a "cause" of MS. This might be a more plausible explanation of the association between emotional trauma and MS development. However, MS pathogenesis is complex, and one could argue that the disease starts many years before the first clinical symptoms that lead to diagnosis.

The MS prodrome has been demonstrated by several studies that suggest that MS may start many years before the clinical diagnosis.¹⁴ Radiologically isolated syndrome (RIS) further argues that MS may be clinically dormant for years, and clinical symptoms may not appear until later in the disease process.¹⁵ One may think that immune attacks on the optic nerves, spinal cord, or areas of the brainstem might be readily symptomatic compared to attacks on other structures of the central nervous system (e.g., periventricular or juxtacortical brain areas) that may be clinically silent. So, while for Sir Augustus d'Este it seemed that the disease started at the time of his visit to the Highlands of Scotland, it is equally plausible that it started years before the first clinical attack. Nevertheless, how could emotional stress play a role in the pathophysiology of MS?

Stress and the Immune System

At times of chronic stress, one may become more susceptible to infections. Reactivation of certain viruses can lead to oral ulcers, increased common cold symptoms, or other illnesses. For example, stress can reactivate herpes simplex type 1 and interestingly, EBV.^16,17 In MS, the immune system is dysregulated and has an autoimmune component. The effect of acute emotional stress differs from that of chronic stress.¹⁸ Several studies have examined the immune responses to both forms of stress.^19-21

Interestingly, acute stress activates cell-mediated immunity, increases immune cell trafficking to areas of injury, and, importantly, increases blood-brain barrier (BBB) permeability by activating resident mast cells in the brain and other areas, including the optic nerves.^22,23 Mast cell activation leads to BBB disruption, which is a key early step in the pathogenesis of MS. Thus, it is plausible that the proinflammatory changes associated with acute stress could be implicated in the pathogenesis of MS. This contrasts with chronic stress, which attenuates various immune responses, including suppressing cell-mediated immunity, but also dysregulate the immune system.

One could establish a biological plausibility for stress playing a role in the proinflammatory responses in MS. Whether it is causal or not, scientists can further explore the potential biologic explanations. While studying the association between acute stress and MS development or disease activity is difficult, several groups have examined the potential association. Many studies, however, have limitations due to the difficult nature of studying such an association, especially in quantifying or defining acute stress in general.

A limited number of studies on MS and stress: What do we know? And what are the challenges?

Rare studies have reported a potential association between MS development and stressful life events, while others reported no association.^24-26 Also, some studies observed an increase in MS relapses or the development of new magnetic resonance imaging (MRI) lesions following stressful life events or wartime, while others failed to show such an association.^26-30 There are few studies directly addressing the potential association between acute emotional stress and MS. The results of published studies are variable, and limitations are numerous. Limitations include the difficulty in measuring acute emotional stress, difficulty in its prediction, and ethical challenges of experimental design and recruiting participants. So, studies have focused on observational aspects, retrospective reviews, and surveys of memories prone to various biases. Rarely was the design of these clinical studies prospective. A few prospective studies reported an association between stressful life events and increased MS relapses and increased number of brain lesions.^27,31,32 Rare clinical trials have attempted to test stress reduction strategies and reported on the modest improvement of patient-reported outcomes and, in one study, a modest improvement in new MRI lesions.^33-35

Overall, several lines of evidence support a potential association between acute emotional stress and MS. Yet, the association is challenging to study, and future research might focus on stress-mitigation strategies and improving coping mechanisms in persons living with MS. It is important to note that it will be very difficult to design prospective studies to examine the potential association between acute emotional trauma and the development of de novo MS. Such studies will require a large number of participants (e.g., hundreds of thousands), long durations of follow-up (e.g., decades), and ways to classify repeated stressful events. An alternative approach is to ask persons newly diagnosed with MS at the time of initial diagnosis about any temporal association between their first symptom and stressful life events. However, this approach would provide some information on any association between the two, but not on causality of the disease itself.

Conclusion

The potential association between acute emotional stress and MS dates to the times of early descriptions of MS. Yet, research has been very limited and challenging. To date, the potential association remains elusive. Lines of evidence, while with limitations, have provided possible biologic explanations for the relationship between MS symptom onset and acute emotional stress. Although avoiding acute emotional stress is nearly impossible, incorporating global stress-coping strategies in early childhood education and secondary education might theoretically have potential beneficial effects on the subsequent risk of MS development or symptom flare-up, depending on a variety of factors.

But for now, when patients and colleagues ask me, “Can acute emotional stress be a ‘trigger’ for MS symptomology?,” my answer will remain, “Potentially, until proven otherwise.”

Rare studies have reported a potential association between MS development and stressful life events, while others reported no association.^24-26 Also, some studies observed an increase in MS relapses or the development of new magnetic resonance imaging (MRI) lesions following stressful life events or wartime, while others failed to show such an association.^26-30 There are few studies directly addressing the potential association between acute emotional stress and MS. The results of published studies are variable, and limitations are numerous. Limitations include the difficulty in measuring acute emotional stress, difficulty in its prediction, and ethical challenges of experimental design and recruiting participants. So, studies have focused on observational aspects, retrospective reviews, and surveys of memories prone to various biases. Rarely was the design of these clinical studies prospective. A few prospective studies reported an association between stressful life events and increased MS relapses and increased number of brain lesions.^27,31,32 Rare clinical trials have attempted to test stress reduction strategies and reported on the modest improvement of patient-reported outcomes and, in one study, a modest improvement in new MRI lesions.^33-35

Overall, several lines of evidence support a potential association between acute emotional stress and MS. Yet, the association is challenging to study, and future research might focus on stress-mitigation strategies and improving coping mechanisms in persons living with MS. It is important to note that it will be very difficult to design prospective studies to examine the potential association between acute emotional trauma and the development of de novo MS. Such studies will require a large number of participants (e.g., hundreds of thousands), long durations of follow-up (e.g., decades), and ways to classify repeated stressful events. An alternative approach is to ask persons newly diagnosed with MS at the time of initial diagnosis about any temporal association between their first symptom and stressful life events. However, this approach would provide some information on any association between the two, but not on causality of the disease itself.

Conclusion

The potential association between acute emotional stress and MS dates to the times of early descriptions of MS. Yet, research has been very limited and challenging. To date, the potential association remains elusive. Lines of evidence, while with limitations, have provided possible biologic explanations for the relationship between MS symptom onset and acute emotional stress. Although avoiding acute emotional stress is nearly impossible, incorporating global stress-coping strategies in early childhood education and secondary education might theoretically have potential beneficial effects on the subsequent risk of MS development or symptom flare-up, depending on a variety of factors.

But for now, when patients and colleagues ask me, “Can acute emotional stress be a ‘trigger’ for MS symptomology?,” my answer will remain, “Potentially, until proven otherwise.”

Sir Augustus d’Este (1794-1848) described the circumstances preceding his development of neurological symptoms as follows:¹ “I travelled from Ramsgate to the Highlands of Scotland for the purpose of passing some days with a Relation for whom I had the affection of a Son. On my arrival I found him dead. Shortly after the funeral I was obliged to have my letters read to me, and their answers written for me, as my eyes were so attacked that when fixed upon minute objects indistinctness of vision was the consequence: Soon after I went to Ireland, and without any thing having been done to my eyes, they completely recovered their strength and distinctness of vision…" He then described a clinical course of relapsing-remitting neurologic symptoms merging into a progressive stage of unrelenting illness, most fitting with what we know today as multiple sclerosis (MS).¹ Why did Sir Augustus d'Este connect the event of the unexpected death to the onset of a lifelong neurologic disease?

Jean-Martin Charcot first described MS in a way close to what we know it as today. Charcot considered stress a factor in MS. He linked grief, vexation, and adverse changes in social circumstances to the onset of MS at that time.² I, as a practicing MS specialist, am surprised neither by Sir Augustus d'Este's diary nor by Charcot's earlier assessments of MS triggers.³ As I write this narrative, I think of the many times I heard from people diagnosed with MS. "It happened to me because of stress" is a statement not estranged from my daily clinical practice

MS as a multifactorial disease

It is tempting to make a case for emotional stress as a cause of MS, but one must remember that MS is a very complex disease with unclear etiologies. MS, a treatable but not yet curable disease, is the interplay between the genetics of the host and numerous environmental factors that exploit a susceptible immune system leading to unrelenting immune dysregulation.⁴ Recent studies have brought some pieces of this intricate puzzle together. The role of Epstein-Barr virus (EBV) in the pathogenesis of MS is being dissected.⁵ The possible synergy between vitamin D deficiency, EBV, and certain genetic variations is being studied.⁶ The roles of smoking, environmental toxins, obesity, diet, Western lifestyle, and the gut microbiome are some of the top areas of clinical, translational, and basic research.^7-11 But what about emotional stress? Where does it fit, if anywhere, in the current research paradigm?

Emotional stress and MS—Causality or not?

In the scientific method, several criteria must be proven for an element to be suspected in the etiology of a disease.¹² First, the suspect element must be present before the disease starts—i.e., a temporal association. Second, there must be a plausible biological explanation of how the suspect element acts in the disease's causation. Third, other variables that could confound the picture must be controlled for or dismissed. It is clear that no single factor is the cause of MS. By now, MS is agreed upon as a disease caused by multiple factors, some of which remain to be unraveled.⁹ The term "cause" has been utilized more recently by many authors when referring to EBV in relation to MS development, reasoning that in one study, in a small number of individuals with MS, EBV infection preceded the MS clinical diagnosis.¹³ Thus, the temporal association was provided. But does MS start at the onset of clinical symptoms?

For Sir Augustus d'Este, the disease may have started years before he visited the Highlands of Scotland, but only at that visit did MS become clinically apparent. So, the emotional trauma may have acted as a "trigger" for an MS flare-up rather than being a "cause" of MS. This might be a more plausible explanation of the association between emotional trauma and MS development. However, MS pathogenesis is complex, and one could argue that the disease starts many years before the first clinical symptoms that lead to diagnosis.

The MS prodrome has been demonstrated by several studies that suggest that MS may start many years before the clinical diagnosis.¹⁴ Radiologically isolated syndrome (RIS) further argues that MS may be clinically dormant for years, and clinical symptoms may not appear until later in the disease process.¹⁵ One may think that immune attacks on the optic nerves, spinal cord, or areas of the brainstem might be readily symptomatic compared to attacks on other structures of the central nervous system (e.g., periventricular or juxtacortical brain areas) that may be clinically silent. So, while for Sir Augustus d'Este it seemed that the disease started at the time of his visit to the Highlands of Scotland, it is equally plausible that it started years before the first clinical attack. Nevertheless, how could emotional stress play a role in the pathophysiology of MS?

Stress and the Immune System

At times of chronic stress, one may become more susceptible to infections. Reactivation of certain viruses can lead to oral ulcers, increased common cold symptoms, or other illnesses. For example, stress can reactivate herpes simplex type 1 and interestingly, EBV.^16,17 In MS, the immune system is dysregulated and has an autoimmune component. The effect of acute emotional stress differs from that of chronic stress.¹⁸ Several studies have examined the immune responses to both forms of stress.^19-21

Interestingly, acute stress activates cell-mediated immunity, increases immune cell trafficking to areas of injury, and, importantly, increases blood-brain barrier (BBB) permeability by activating resident mast cells in the brain and other areas, including the optic nerves.^22,23 Mast cell activation leads to BBB disruption, which is a key early step in the pathogenesis of MS. Thus, it is plausible that the proinflammatory changes associated with acute stress could be implicated in the pathogenesis of MS. This contrasts with chronic stress, which attenuates various immune responses, including suppressing cell-mediated immunity, but also dysregulate the immune system.

One could establish a biological plausibility for stress playing a role in the proinflammatory responses in MS. Whether it is causal or not, scientists can further explore the potential biologic explanations. While studying the association between acute stress and MS development or disease activity is difficult, several groups have examined the potential association. Many studies, however, have limitations due to the difficult nature of studying such an association, especially in quantifying or defining acute stress in general.
