In the latest issue of the Morbidity and Mortality Weekly Report, the Centers for Disease Control and Prevention recommended hepatitis C virus screening for all adults and all pregnant women – during each of their pregnancies – in areas where prevalence of the infection is 0.1% or greater.

That’s essentially the entire United States; there’s no state with a statewide adult prevalence below 0.1%, and “few settings are known to exist” otherwise, the CDC noted (MMWR Recomm Rep. 2020 Apr 10;69(2):1-17).

The agency encouraged providers to consult state or local health departments or the CDC directly to determine local HCV prevalence. “As a general guide ... approximately 59% of anti-HCV positive persons are HCV RNA positive,” indicating active infection, the agency noted.

The advice was an expansion from the CDC’s last universal screening recommendation in 2012, which was limited to people born from 1945 to 1965; the incidence of acute infections has climbed since then and is highest now among younger people, so the guideline needed to be revisited, explained authors led by Sarah Schillie, MD, of the CDC’s Division of Viral Hepatitis, Atlanta.

The U.S. Preventive Services Task Force also recently recommended universal adult screening after previously limiting it to baby boomers.

As for pregnancy, the CDC’s past advice was to screen pregnant women with known risk factors, but that needed to be revisited as well. For one thing, the American Association for the Study of Liver Diseases and the Infectious Diseases Society of America have since recommended testing all pregnant women.

But also, the CDC said, it’s an opportune time for screening because “many women only have access to health care during pregnancy and the immediate postpartum period,” when treatment, if needed, can be started. Plus, HCV status is important for management decisions, such as using amniocentesis in positive women instead of chorionic villus sampling.

The rest of CDC’s 2012 recommendations stand, including screening all people with risk factors and repeating screening while they persist. Also, “any person who requests hepatitis C testing should receive it, regardless of disclosure of risk,” because people might be reluctant to report things like IV drug use, the authors said.

Screening in the guidelines means an HCV antibody test, followed by a nucleic acid test to check for active infection. The CDC encouraged automatic reflex testing, meaning immediately checking antibody positive samples for HCV RNA. RNA in the blood indicates active, replicating virus.

The new recommendations penciled out in modeling, with an incremental cost-effectiveness ratio (ICER) for universal adult screening of approximately $36,000 per quality-adjusted life year (QALY) gained, and an ICER of approximately $15,000 per QALY gained for pregnancy screening, where HCV prevalence is 0.1%; the 0.1% cost/benefit cutpoint was one of the reasons it was chosen as the prevalence threshold. An ICER under $50,000 is the conservative benchmark for cost-effectiveness, the authors noted.

There was no external funding, and the authors had no disclosures.

A large pooled analysis of almost 24,000 women showed women who breastfed had a 24% lower risk of invasive ovarian cancer.

Bonnie Becker/MDedge News

Multiple studies have reported a link between breastfeeding and a reduced risk of ovarian cancer, but other studies have found no such link, and the evidence that the protective effects differ by histologic types has been inconclusive.

“This large study with extensive information on breastfeeding provides epidemiological evidence that breastfeeding, a potentially modifiable factor, may confer significant reduction in ovarian cancer risk, including high-grade serous, the deadliest subtype,” Ana Babic, PhD, of Dana-Farber Cancer Institute and Harvard Medical School, both in Boston, and colleagues reported in JAMA Oncology.

Dr. Babic led the study of a pooled analysis of women from 13 case-control studies participating in the Ovarian Cancer Association Consortium. The study evaluated 9,973 women who had ovarian cancer and 13,843 controls, with a mean age of 57 and 56 years, respectively. The data were collected over 20 years through December 2009. Dr. Babic and colleagues claimed that this is the largest study of breastfeeding and ovarian cancer risk to date.

Besides calculating a lower risk of invasive cancer, the analysis also determined that any breastfeeding was associated with a 28% lower risk of borderline cancers, compared with women who never breastfed. “Among invasive tumors, the association was statistically significant for high-grade serous, endometrioid and clear-cell tumors,” Dr. Babic and colleagues wrote, with 25%, 27% and 22% reduced risk, respectively. The researchers also noted a similar, although not statistically significant, reduced risk for low-grade serous tumors, but no such association for mucinous tumors. For borderline tumors, breastfeeding correlated with a 32% lower risk for mucinous tumors and 23% reduction in risk for serous tumors.

The analysis included five studies with data on exclusive breastfeeding. Women who breastfed exclusively for at least 3 months had a 19% reduced risk of ovarian cancer, compared with women who never breastfed, while women who breastfed albeit not exclusively for 3 months had a 30% reduced risk. The analysis also found an association between longer duration of breastfeeding and reduced risk of invasive ovarian cancer: less than 3 months duration per child was associated with an 18% lower risk, while more than 12 months was associated with a 34% lower risk (P < .001). Other factors that seemed to mitigate risk were older age when breastfeeding and breastfeeding within the previous 10 years.

One of the strengths of the studies is that it separated low-grade and the more common and deadly high-grade serous tumors. While the analysis found similar trends with endometrioid ovarian cancers, it didn’t reach a conclusion about other invasive histotypes because there were fewer cases to evaluate. Because the study population was predominantly white, the researchers acknowledged they could not sufficiently evaluate patterns among blacks, Asian, and other ethnic groups. “The association between breastfeeding and ovarian cancer needs to be investigated in large populations of other races and ethnicities,” Dr. Babic and colleagues added.

Nonetheless, they noted that their results support the World Health Organization recommendations of at least 6 months of exclusive breastfeeding and continued breastfeeding with complementary foods for 2 years or more, even though breastfeeding for less than 3 months is associated with a significant reduction in ovarian cancer risk.

The study is significant because of its “thoughtful approach to addressing potential confounders (parity, age, etc.),” said David Barrington, MD, gynecologic oncology fellow at Ohio State University James Cancer Center in Columbus.

“For general obstetricians and gynecologists, this study provides an additional reason to advocate for breastfeeding,” Dr. Barrington added. “This data should be included in a thorough discussion of the multitudes of benefits breastfeeding provides to both the infant and the mother.”

He added that future studies should evaluate breastfeeding and ovarian cancer risks in a more ethnically diverse population. “Understanding the potential impact of modifiable risk factors for ovarian cancer is paramount to overcoming racial disparities in outcomes,” Dr. Barrington said.

The study was supported by the U.S. National Cancer Institute. Dr. Babic reported grants from the U.S. National Institutes of Health. Some coauthors reported grants from the NIH, the National Health and Medical Research Council of Australia, the Federal Ministry of Education and Research of Germany, the Danish Cancer Society, or the Mermaid I Project. Some coauthors had no disclosures to report. Dr. Barrington has no relevant relationships to disclose.

Maternal preconception exposure to phthalates was associated with increased risk of preterm birth, according to a study of 420 births to subfertile couples over a 13-year period.

Previous studies have shown increased risk of preterm birth associated with prenatal exposure to phthalates, which are commonly found in a range of household and commercial products as well as medical equipment and some pharmaceuticals.

“Our results suggest that female exposure to [4 di(2-ethylhexyl) phthalate] DEHP before conception might be an unrecognized risk factor for adverse pregnancy outcomes, often overlooked in clinical practice,” wrote Yu Zhang of the department of environmental health at Harvard T.H. Chan School of Public Health, Boston, and colleagues.

The prospective cohort study evaluated preconception urinary levels of phthalates and phthalate substitutes in 419 women and 229 men participating in the Environment and Reproductive Health (EARTH) study, a cohort of couples seeking fertility care at the Massachusetts General Hospital Fertility Center. The study cohort gave birth during 2005-2018. The average gestational age of the 420 singleton children born to this cohort was 39 weeks, with 8% (n = 34) born preterm.

Adjusted models showed that maternal preconception urinary concentrations of phthalates and of cyclohexane-1, 2-dicarboxylic acid monohydroxy isononyl ester (MHiNCH), a metabolite of a nonphthalate plasticizer substitute, were associated with a 50% and 70% increased risk of preterm birth, respectively (P = .01, .11), according to results published in JAMA Network Open .

Sensitivity analysis showed that maternal preconception MHiNCH concentrations above the median were associated with a fourfold increased risk of preterm birth (risk ratio, 4.02; P = .08), Maternal preconception MHiNCH concentrations were associated with an average 2-day reduction in gestational age (P = .02).

Covariate-adjusted models found that paternal urinary phthalate metabolite concentrations were associated with an increased risk of preterm birth (RR, 1.41; P = .09), but this association was attenuated toward zero (RR, 1.06) in models that accounted for maternal preconception phthalate concentrations. Sensitivity analysis of 228 couples found the associations of maternal preconception phthalate metabolite concentrations and preterm birth remained robust in three different models: a twofold increased risk in covariate-adjusted models (P < .001); an almost fivefold increased risk in adjusting for prenatal levels (RR, 4.98; P < .001); and a twofold risk (P = .001) in adjusting for paternal levels. “Couple-based analyses confirmed the results for an association between maternal preconception DEHP concentrations and increased risk of preterm birth,” the investigators said.

“To our knowledge, this is the first study evaluating couples’ exposure to phthalate metabolites during the preconception window and its association with preterm birth,” the researchers wrote. “Our findings support a novel hypothesis: Maternal phthalate exposure during the critical period before conception may be associated with shorter gestation.”

“This study is consistent with several, but not all, prior studies supporting maternal prenatal exposure to phthalates increase preterm birth,” said Mark P. Trolice, MD, professor of obstetrics and gynecology at the University of Central Florida, Orlando. “The uniqueness of the current study was the assessment of couples’ exposures and the outcome, though paternal exposure to phthalates did not demonstrate a significant association.”

Dr. Trolice noted that about 25% of women in the study were smokers, but the study didn’t adjust for tobacco use and phthalate exposure, and 85% of the women were white. He urged caution in applying the study results in practice, adding that the study didn’t adjust for method of conception. “Assisted reproductive technology, multiple gestation, and advanced age are all known risk factors for preterm birth,”

The National Institute of Environmental Health Science funded the study. Two study coauthors received grants from the NIEHS, one coauthor received grants from the National Institutes of Health, and one received a grant from the Canadian Institutes of Health Research. No other disclosures were reported. Dr. Trolice has no financial relationships to disclose.

Combination therapy with apatinib and camrelizumab shows promising antitumor activity in patients with advanced cervical cancer, regardless of programmed death–ligand 1 (PD-L1) expression, according to preliminary findings from a phase 2 study.

Dr. Chunyan Lan

Apatinib, an inhibitor of vascular endothelial growth factor receptor-2, and camrelizumab, an anti-PD-1 monoclonal antibody, produced an objective response rate of 60% in evaluable patients.

Chunyan Lan, MD, of Sun Yat-sen University Cancer Center in Guangzhou, China, and colleagues reported these results in an abstract that had been slated for presentation at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer. The meeting was canceled because of the COVID-19 pandemic. The following data differ somewhat from the abstract.

Dr. Lan and colleagues reported results in 45 patients who had progressed after at least one line of systemic chemotherapy for metastatic, recurrent, or persistent cervical cancer, and had measurable disease. Patients had a median age of 51 years and an Eastern Cooperative Oncology Group performance status of 0-1. They were enrolled at four centers in China between Jan. 21 and Aug. 1, 2019.

Treatment consisted of oral apatinib at a dose of 250 mg once daily and intravenous camrelizumab at a dose of 200 mg every 2 weeks until disease progression, unacceptable toxicity, or consent withdrawal.

As of Jan. 22, 2020, 25 of 42 efficacy-evaluable patients had achieved a response. Two patients had a complete response, 23 had a partial response, and 12 had stable disease.

“We saw responses in patients regardless of PD-L1 expression,” Dr. Lan said. “In our study, 34% were PD-L1 negative, and the response rate is 65% in PD-L1-positive and 50% in PD-L1-negative [patients].”

The median duration of response was not reached, she added.

The median follow-up was 9.2 months, with the last patient enrolled having 6 months of follow-up. At the data cutoff, 19 patients had disease progression, and 8 had died of their disease.

The median overall survival also was not reached, Dr. Lan said, but overall survival at 9 months was 80%. The median progression-free survival was 7.6 months, and the 6-month progression-free survival rate was 58%.

Grade 3 or greater treatment-related adverse events occurred in 68.9% of patients; adverse events occurring in at least 5% of patients included hypertension (22.2%), fatigue (15.6%), anemia (13.3%), and thrombocytopenia (6.7%).

“Nineteen patients were still on treatment at the data cutoff date, and 26 patients discontinued the study,” Dr. Lan said. “The most common reason to discontinue was disease progression, and three patients discontinued the study due to adverse events.”

“These preliminary results are very encouraging,” Dr. Lan said. “As we know, pembrolizumab is approved as the second-line therapy in recurrent cervical cancer [in] PD-L1-positive patients, and the objective response rate with pembrolizumab monotherapy for recurrent cervical cancer is only 17%, as reported in KEYNOTE-028 [J Clin Oncol. 2017 Dec 20;35(36):4035-41].”

Furthermore, apatinib monotherapy has been studied with only modest results.

“But in our study, this combination is really effective in recurrent cervical cancer, and we see a very durable response,” she said, again emphasizing that those responses occurred regardless of PD-L1 expression. “So this is important. ... We think our findings expand the opportunity of patients with recurrent cervical cancer to receive immune therapy.”

Study participants will be followed for 2 years, Dr. Lan noted.

She reported having no disclosures. The study is sponsored by Sun Yat-sen University.

The American College of Obstetricians and Gynecologists (ACOG) posted a useful resource on its website on March 30 for clinicians practicing ambulatory gynecology. The guidance, “COVID-19 FAQs for Obstetrician–Gynecologists, Gynecology” (https://www.acog.org/), is based on expert opinion and is intended to supplement guidance from the Centers for Disease Control and Prevention as well as previously issued ACOG guidance.¹

Which patients need to be seen, and when

The ACOG guidance provides examples of patients needing in-person appointments, video or telephone visits, or for whom deferral of a visit until after the COVID-19 outbreak would be appropriate. Highlights include:

In-person appointments

• suspected ectopic pregnancy
• profuse vaginal bleeding

Video or telephone visits

• contraceptive counseling and prescribing
• management of menopausal symptoms

Deferral of a visit until after the COVID-19 outbreak

• routine well-woman visits for average-risk patients.

Cervical screening

With respect to patients with abnormal cervical cancer screening results, ACOG recommends the ASCCP’s guidance that²:

• for patients with low-grade test results, colposcopy/cervical biopsies be deferred up to 6 to 12 months
• for patients with high-grade results, colposcopy/cervical biopsies be performed within 3 months.

Contraception

Regarding contraceptive services, the ACOG guidance suggests that placement of intrauterine devices (IUDs) and contraceptive implants should continue “where possible.” If initiation of long-acting reversible contraception (LARC) is not feasible, the guidance recommends that use of self-administered contraceptives (including subcutaneous injections, oral, transdermal patch, and vaginal ring contraception) be encouraged as a bridge to later initiation of LARC.

The guidance suggests that removal of IUDs and implants be postponed when possible.

Finally, the guidance suggests that patients with an existing IUD or implant who seek removal and replacement of their contraceptives be counseled regarding extended use of these devices.

Individualize your approach

ACOG emphasizes that no single solution applies to all situations and that each practice or clinic should evaluate the individual situation, including the availability of local and regional resources, staffing, and personal protective equipment; the prevalence of COVID-19 in the region; and the type of practice.

A roadmap for care

This guidance from ACOG should help clinicians caring for women during the COVID-19 outbreak to counsel and guide patients in a prudent manner.

STOWE, VT. – Menstrual migraine is more disabling than migraine that has no association with menstruation, said Susan Hutchinson, MD, director of the Orange County Migraine and Headache Center in Irvine, Calif. Compared with headaches associated with nonmenstrual migraine, headaches resulting from menstrual migraine last longer and are more difficult to treat. They tend to be associated with morning awakening and with nausea and vomiting. But in younger women with regular menses, menstrual migraine is predictable. The disorder offers “an incredible chance to be preemptive and think about short-term preventive strategies,” Dr. Hutchinson said at the annual meeting of the Headache Cooperative of New England.

What is menstrual migraine?

Menstrual migraine occurs during the perimenstrual window, which begins at 2 days before onset of bleeding and ends at 3 days of menses. Migraine that occurs during this window at least two-thirds of the time satisfies the criteria for menstrual migraine. A prospective headache diary is recommended, but not required, for making the diagnosis, said Dr. Hutchinson.

Most women with migraine have perimenstrual exacerbation of their headaches, as well as headaches at other times of the month. This phenotype is called menstrually related migraine. Pure menstrual migraine is migraine associated exclusively with menses. The International Classification of Headache Disorders-3 recognizes that menstrual migraine can be with or without aura. A headache diary can help distinguish between menstrual migraine and menstrually related migraine.

For pure menstrual migraine, it is appropriate to treat during the perimenstrual window. Preventive treatment may not be necessary throughout the month, said Dr. Hutchinson. Furthermore, hormonal treatment is the type of therapy most likely to be effective, she added. Menstrually related migraine requires a broader approach.
 

Gathering information during the visit

A 1972 study by Somerville and colleagues indicated that a decrease in estrogen is a powerful trigger of migraine. The investigators administered estrogen (i.e., intramuscular estradiol) or progesterone during the late luteal phase to women with menstrual migraine. Among women who received estrogen, migraine onset was postponed until the estrogen level decreased. The administration of progesterone postponed bleeding, but did not affect migraine. Progesterone treatment prevents migraine effectively on occasion, but estrogen treatment is much more likely to be a successful strategy, said Dr. Hutchinson.

Neurologists should ask certain questions of women with migraine, whether the patients are new or not, to gather information needed to make treatment decisions. For example, it is advisable to ask a woman whether she often has a headache with her period. “You may not want to use the word ‘migraine,’ because many women have been taught that headache is part of PMS,” said Dr. Hutchinson. Asking a woman how pregnancy, delivery, and breastfeeding affected her headaches can add further detail to her history and provide insight about the effects of hormonal changes. Asking what type of birth control the woman is taking can influence the choice of treatment, since some therapies are not appropriate during pregnancy.
 

Available treatments

NSAIDs are among the treatments that neurologists should consider for the short-term prevention of menstrually related migraine, said Dr. Hutchinson. A study of 35 patients by Sances et al. compared placebo with 550 mg of naproxen sodium given twice daily. Treatment began at 7 days before bleeding onset and continued until the 6th day of menses. Patients underwent treatment for three menstrual cycles. Naproxen sodium significantly reduced headache intensity, headache duration, and the number of headache days, compared with baseline. Treatment was superior to placebo at 3 months. Approximately 33% of patients in the active group were headache free, but no controls were.

Magnesium is another potentially effective option. Facchinetti et al. compared placebo with 360 mg/day of magnesium in a study of 20 patients. Treatment, which was given for two cycles, began at 15 days before menses and ended at the start of menses. Compared with placebo, magnesium reduced the number of headache days and the total pain index. Magnesium is inexpensive, but it causes diarrhea in some patients. “Some women choose to take magnesium all month long, other women start at around ovulation,” said Dr. Hutchinson.

Hormonal treatments are another possible option for the short-term prevention of menstrually related migraine. For women who do not plan to become pregnant, oral contraceptive pills can keep estrogen levels high enough to prevent menstrually related migraine. Gynecologists may suggest that a woman take the pill continuously, skipping the placebo, for an entire year, but Dr. Hutchinson recommends that a woman stop taking the pill for 4 days approximately every 3 months. This discontinuation allows for withdrawal bleeding, but is not likely to cause a prolonged enough decrease in estrogen to provoke migraine, she said. The continuous contraceptive ring, which is inserted vaginally, is an alternative to the pill.

For women who do not want or need contraception, an estrogen patch or gel may be appropriate. Two studies in the 1980s found that a gel containing 1.5 mg of estradiol per 2.5 g reduced migraine frequency, duration, and severity. These studies did not gather long-term safety data, however. A 2006 study by MacGregor et al. found that percutaneous estradiol was associated with a 22% reduction in the number of migraine days, as well as with decreases in headache severity and associated nausea. But the risk of migraine during the 5 days following treatment cessation was increased by 40%. This finding suggests that the treatment period should be extended, said Dr. Hutchinson.

In addition to the timing, the dose of treatment affects the outcome. Smite et al. found no benefit of a 50-mcg dose of estradiol, compared with placebo. Pradalier and colleagues found that a 100-mcg dose was associated with decreased use of rescue medication, compared with a 25-mcg dose. These studies did not gather long-term safety data.
 

Oral contraceptives and the risk of stroke

Combined oral contraceptives, however, are associated with increased risk of stroke in women with migraine with aura. The dose of estrogen in the contraceptive affects the level of risk, said Dr. Hutchinson. A systematic review by Sheikh et al. found that high-dose ethinyl estradiol (i.e., greater than 50 mcg) was associated with a higher risk of ischemic and hemorrhagic stroke than low-dose ethinyl estradiol (i.e., less than 50 mcg) was. A 20-mcg dose was associated with an odds ratio of stroke of 1.7. Furthermore, among women using combined hormonal contraception, the risk of stroke was higher in women with aura than in women without aura.

“I like to look at the big picture,” said Dr. Hutchinson. “There’s a big difference between a woman who has one or two auras a year that last for 10 minutes and a woman who has complicated aura. I’m going to approach [the latter] woman differently.”

No consensus guidelines for prescribing combined oral contraceptives to women with migraine and aura have been developed. The International Headache Society says that physicians may prescribe low-dose estrogen to women with simple visual aura. The American College of Obstetricians and Gynecologists recommends progestin-only intrauterine or barrier contraception for this population. The World Health Organization holds that estrogen-containing contraception is contraindicated in all women who have migraine with aura.

“If you have women who have migraine without aura, low–estrogen dose combined hormonal contraceptives can be quite appropriate,” said Dr. Hutchinson. “I would tend to go with a 10- or 20-mcg low dose. It could be an option for women with migraine with aura, but only if the benefits outweigh the risks.” In a study by Calhoun et al., the vaginal ring was associated with reduced aura frequency in women with migraine and aura.
 

Choosing preventive and rescue medications

Although no triptan has FDA approval for the short-term prevention of menstrual migraine, studies have suggested that they are effective. In a study by Sances and colleagues, a twice-daily 1-mg dose of naratriptan taken 6 days perimenstrually reduced the frequency of menstrual-related migraine. At least 50% of treated patients in the study had no menstrual-related migraine. Silberstein and colleagues found that 59% of women who took 2.5 mg of frovatriptan twice daily had no menstrual-related migraine during the 6-day perimenstrual period, compared with 33% of women who received placebo.

Patients with menstrual migraine sometimes need rescue medication. Sumatriptan, either as an injection or an inhaled therapy, is one option. Another injectable option is a 60-mg intramuscular dose of ketorolac. Finally, occipital or sphenopalatine nerve block may be effective as well.

Dr. Hutchinson reported consulting for or serving on the advisory board of Alder, Allergan, Amgen, Biohaven, electroCore, Lilly, Novartis, Supernus, Teva, Theranica, and Upsher-Smith. She has served on speakers bureaus for Allergan, Amgen, electroCore, Lilly, Novartis, Supernus, and Teva.

Furthermore, among women using combined hormonal contraception, the risk of stroke was higher in women with aura than in women without aura.

“I like to look at the big picture,” said Dr. Hutchinson. “There’s a big difference between a woman who has one or two auras a year that last for 10 minutes and a woman who has complicated aura. I’m going to approach [the latter] woman differently.”

No consensus guidelines for prescribing combined oral contraceptives to women with migraine and aura have been developed. The International Headache Society says that physicians may prescribe low-dose estrogen to women with simple visual aura. The American College of Obstetricians and Gynecologists recommends progestin-only intrauterine or barrier contraception for this population. The World Health Organization holds that estrogen-containing contraception is contraindicated in all women who have migraine with aura.

“If you have women who have migraine without aura, low–estrogen dose combined hormonal contraceptives can be quite appropriate,” said Dr. Hutchinson. “I would tend to go with a 10- or 20-mcg low dose. It could be an option for women with migraine with aura, but only if the benefits outweigh the risks.” In a study by Calhoun et al., the vaginal ring was associated with reduced aura frequency in women with migraine and aura.
 

Choosing preventive and rescue medications

Although no triptan has FDA approval for the short-term prevention of menstrual migraine, studies have suggested that they are effective. In a study by Sances and colleagues, a twice-daily 1-mg dose of naratriptan taken 6 days perimenstrually reduced the frequency of menstrual-related migraine. At least 50% of treated patients in the study had no menstrual-related migraine. Silberstein and colleagues found that 59% of women who took 2.5 mg of frovatriptan twice daily had no menstrual-related migraine during the 6-day perimenstrual period, compared with 33% of women who received placebo.

Patients with menstrual migraine sometimes need rescue medication. Sumatriptan, either as an injection or an inhaled therapy, is one option. Another injectable option is a 60-mg intramuscular dose of ketorolac. Finally, occipital or sphenopalatine nerve block may be effective as well.

STOWE, VT. – Menstrual migraine is more disabling than migraine that has no association with menstruation, said Susan Hutchinson, MD, director of the Orange County Migraine and Headache Center in Irvine, Calif. Compared with headaches associated with nonmenstrual migraine, headaches resulting from menstrual migraine last longer and are more difficult to treat. They tend to be associated with morning awakening and with nausea and vomiting. But in younger women with regular menses, menstrual migraine is predictable. The disorder offers “an incredible chance to be preemptive and think about short-term preventive strategies,” Dr. Hutchinson said at the annual meeting of the Headache Cooperative of New England.

What is menstrual migraine?

Menstrual migraine occurs during the perimenstrual window, which begins at 2 days before onset of bleeding and ends at 3 days of menses. Migraine that occurs during this window at least two-thirds of the time satisfies the criteria for menstrual migraine. A prospective headache diary is recommended, but not required, for making the diagnosis, said Dr. Hutchinson.

Most women with migraine have perimenstrual exacerbation of their headaches, as well as headaches at other times of the month. This phenotype is called menstrually related migraine. Pure menstrual migraine is migraine associated exclusively with menses. The International Classification of Headache Disorders-3 recognizes that menstrual migraine can be with or without aura. A headache diary can help distinguish between menstrual migraine and menstrually related migraine.

For pure menstrual migraine, it is appropriate to treat during the perimenstrual window. Preventive treatment may not be necessary throughout the month, said Dr. Hutchinson. Furthermore, hormonal treatment is the type of therapy most likely to be effective, she added. Menstrually related migraine requires a broader approach.
 

Gathering information during the visit

A 1972 study by Somerville and colleagues indicated that a decrease in estrogen is a powerful trigger of migraine. The investigators administered estrogen (i.e., intramuscular estradiol) or progesterone during the late luteal phase to women with menstrual migraine. Among women who received estrogen, migraine onset was postponed until the estrogen level decreased. The administration of progesterone postponed bleeding, but did not affect migraine. Progesterone treatment prevents migraine effectively on occasion, but estrogen treatment is much more likely to be a successful strategy, said Dr. Hutchinson.

Neurologists should ask certain questions of women with migraine, whether the patients are new or not, to gather information needed to make treatment decisions. For example, it is advisable to ask a woman whether she often has a headache with her period. “You may not want to use the word ‘migraine,’ because many women have been taught that headache is part of PMS,” said Dr. Hutchinson. Asking a woman how pregnancy, delivery, and breastfeeding affected her headaches can add further detail to her history and provide insight about the effects of hormonal changes. Asking what type of birth control the woman is taking can influence the choice of treatment, since some therapies are not appropriate during pregnancy.
 

Available treatments

NSAIDs are among the treatments that neurologists should consider for the short-term prevention of menstrually related migraine, said Dr. Hutchinson. A study of 35 patients by Sances et al. compared placebo with 550 mg of naproxen sodium given twice daily. Treatment began at 7 days before bleeding onset and continued until the 6th day of menses. Patients underwent treatment for three menstrual cycles. Naproxen sodium significantly reduced headache intensity, headache duration, and the number of headache days, compared with baseline. Treatment was superior to placebo at 3 months. Approximately 33% of patients in the active group were headache free, but no controls were.

Magnesium is another potentially effective option. Facchinetti et al. compared placebo with 360 mg/day of magnesium in a study of 20 patients. Treatment, which was given for two cycles, began at 15 days before menses and ended at the start of menses. Compared with placebo, magnesium reduced the number of headache days and the total pain index. Magnesium is inexpensive, but it causes diarrhea in some patients. “Some women choose to take magnesium all month long, other women start at around ovulation,” said Dr. Hutchinson.

Hormonal treatments are another possible option for the short-term prevention of menstrually related migraine. For women who do not plan to become pregnant, oral contraceptive pills can keep estrogen levels high enough to prevent menstrually related migraine. Gynecologists may suggest that a woman take the pill continuously, skipping the placebo, for an entire year, but Dr. Hutchinson recommends that a woman stop taking the pill for 4 days approximately every 3 months. This discontinuation allows for withdrawal bleeding, but is not likely to cause a prolonged enough decrease in estrogen to provoke migraine, she said. The continuous contraceptive ring, which is inserted vaginally, is an alternative to the pill.

For women who do not want or need contraception, an estrogen patch or gel may be appropriate. Two studies in the 1980s found that a gel containing 1.5 mg of estradiol per 2.5 g reduced migraine frequency, duration, and severity. These studies did not gather long-term safety data, however. A 2006 study by MacGregor et al. found that percutaneous estradiol was associated with a 22% reduction in the number of migraine days, as well as with decreases in headache severity and associated nausea. But the risk of migraine during the 5 days following treatment cessation was increased by 40%. This finding suggests that the treatment period should be extended, said Dr. Hutchinson.

In addition to the timing, the dose of treatment affects the outcome. Smite et al. found no benefit of a 50-mcg dose of estradiol, compared with placebo. Pradalier and colleagues found that a 100-mcg dose was associated with decreased use of rescue medication, compared with a 25-mcg dose. These studies did not gather long-term safety data.
 

Oral contraceptives and the risk of stroke

Combined oral contraceptives, however, are associated with increased risk of stroke in women with migraine with aura. The dose of estrogen in the contraceptive affects the level of risk, said Dr. Hutchinson. A systematic review by Sheikh et al. found that high-dose ethinyl estradiol (i.e., greater than 50 mcg) was associated with a higher risk of ischemic and hemorrhagic stroke than low-dose ethinyl estradiol (i.e., less than 50 mcg) was. A 20-mcg dose was associated with an odds ratio of stroke of 1.7. Furthermore, among women using combined hormonal contraception, the risk of stroke was higher in women with aura than in women without aura.

“I like to look at the big picture,” said Dr. Hutchinson. “There’s a big difference between a woman who has one or two auras a year that last for 10 minutes and a woman who has complicated aura. I’m going to approach [the latter] woman differently.”

Cervical pannus is a disease that could easily develop in an active-duty soldier or veteran. The disease has been associated with trauma and rheumatoid arthritis, or can be idiopathic. For years, cervical pannus has been closely tied to rheumatoid arthritis; however, a study published in 2019 showed that only 28% of patients with cervical pannus had an associated diagnosis of rheumatoid arthritis.¹ In the same study, 18% of patients had undergone some type of prior cervical spine surgery as the next most common cause. The condition also can occur years after an injury.

Background

In the US, 42,000 veterans are living with spinal cord disease, and thousands of these veterans have surgery every year.² Service men and women and veterans are at risk for cervical pannus as they age especially if they have a history of rheumatoid arthritis, cervical spine surgery, trauma, and numerous other causes. It is critical for health care providers who treat this population to understand cervical pannus, how to recognize it, and how to identify patients at risk. A cervical pannus can be life threatening if not detected and treated properly.

There is no clear definition for cervical pannus. Some researchers think of it as the chronically inflamed synovial membrane in patients with rheumatoid arthritis (RA); others consider it as a specialized synovial membrane derived from vascular soft tissue structures at or near the bone synovial membrane.³ The pathogenesis for developing a pannus is not well understood, and little is known when a pannus begins or its initial location. A pannus formation can occur in any synovial joint in the body, such as wrists, metacarpophalangeal joint, proximal interphalangeal joint, and cervical joints.

A cervical pannus can cause serious complications. It can lead to a cervical subluxation in up to 4% of patients with RA, or it also can occur spontaneously in some patients without RA especially those with trauma or cancer.⁴

There are 2 suggested mechanisms by which the synovial membrane proliferates. It was originally believed that T cells from the chronic inflamed joint lead to the pannus formation by initiating an autoimmune reaction through the production of different cytokines against arthritogenic agents.^3-5 These cytokines increase inflammation by recruiting neutrophils and activating various kinds of macrophages that might lead to increased osteoclast activity.⁶ Osteoclastic activity can damage bone and allow the synovium to penetrate the bone, forming the pannus.

Another proposed mechanism is that the synovial cells hyperpolarize and hypertrophy automatically without T-cell help by expressing oncogenes and their proteins.³ In either case, angiogenesis follows this proliferation and increases the influx of inflammatory cells into the joints, which can lead to more destruction.⁷ This increase in blood supply to the synovial membrane is important in the growth of the pannus and can have a damaging effect to cartilage, bone, and joints.^4,7

Cervical pannus can progress in patients with prolonged use of corticosteroids.⁸ Because a pannus can put pressure on any segment of the cervical spine and the cranio-cervical junction leading to cervical instability, patients with this condition may present with a variety of clinical symptoms.⁹ The most frequently reported clinical features include neck pain, easy fatigability, difficulty walking, abnormal gait, increased clumsiness, and numbness and tingling in the arms. Patients also may complain of neck stiffness and decreased neck motion.¹⁰Cervical pannus is most frequently seen in patients with RA. However, patients without a RA diagnosis and incidental atlantoaxial pannus on cervical spine magnetic resonance imaging (MRI) are unlikely to have previously undiagnosed RA.¹¹

Case Presentation

A 70-year-old white woman presented to the neurology clinic at Gretna Medical Center in Virginia in December 2016 with constant headache and imbalance that started in September 2016. She characterized the pain as predominately pressure (6 on a 10-point pain scale) with occasional shooting pains. The pain started at the left occipital lobe and radiated toward the left temporal lobe and left eye. The patient also stated that it was very difficult to lay her head down on a pillow to sleep and that she had to use a recliner in order to sleep over the past 3 months. She reported that the headache felt slightly worse if she had a lot of repetitive head and neck movements during the day. There was no photophobia, phonophobia, nausea, vomiting, facial paresthesias, lacrimation, nasal congestion, confusion, or impaired speech.

The patient’s lack of balance, which resulted in an unsteady gait, had started 1 month before and had increased significantly in the past 2 to 3 weeks. She stated that the unsteady gait was associated with numbness in her right upper and lower extremities, although more intense in the right lower extremity. Aside from the headaches, paresthesia, and unsteady gait, the patient reported no other major symptoms. She did not smoke tobacco or drink alcohol. Her family history revealed that her brothers had heart disease.

The patient’s vital signs at physical examination included heart rate, 83 beats per minute; blood pressure, 159/75 mm hg; temporal temperature, 97.9 °F; and respiratory rate, 20 breaths per minute. The patient’s gait was unsteady, needing stabilization by holding on to her husband’s arm, slightly favoring right lower extremity. Finger-to-nose test, rapid alternating movements, heel-knee-shin testing were all normal. The Romberg sign was positive. The patient could rise on toes and heels with slight balance disturbance. Deep tendon reflexes and reflexes in the upper and lower extremities was symmetric 2+ bilaterally. Musculoskeletal examination revealed strength and tone in all major muscle groups and demonstrated symmetrical movements with no fasciculation noted. A rheumatologic evaluation showed no abnormalities, including inspection of hands, feet, major joints, and other range of motion, besides her neck. The rest of the physical, cognitive, and neurologic examination findings were otherwise unremarkable. A routine rheumatologic laboratory evaluation was negative.

A head computed tomography ordered before coming to the clinic showed normal results. An MRI of the head was obtained to evaluate for ischemic cause or structural abnormality (Figures 1 and 2). Given the patient’s presentation and the pattern seen on the MRI results, it was determined that large pannus posterior to the dens, severely narrowing the spinal canal, was most likely the diagnosis. A second opinion confirmed the diagnosis, and a second MRI revealed stabilization with no signs of enhancement.

The patient was advised to meet with a neurosurgeon to remove the pannus. The patient agreed on occiput to C2 posterior instrument arthrodesis as well as decompression. A plain film radiograph showed C2-occipital repair after surgery (Figure 3). The patient recovered in the neurosurgical intensive care unit, and the rest of the recovery was uncomplicated. She showed some improvement in her headaches and unsteady gait. A postoperative pathologic evaluation of tissue was not available. She was referred to a rheumatologist to rule out an autoimmune disease as the cause for this pannus, but no autoimmune disease was found.

Discussion

Cervical pannus is relatively uncommon in those without RA. However, there are multiple reasons that a patient could develop a cervical pannus. Cervical pannus in RA and cervical pannus without RA may mimic each other clinically, but medical management is distinctly different. Consequently, a rheumatology consult is necessary to ensure that there is no undiagnosed autoimmune disorder. Our patient did not have RA, and a neurosurgery intervention was needed to manage her headaches and unsteady gait. Although we could not isolate a cause of this patient’s cervical pannus development, we believed that nonintervention would adversely affect this patient.

The course of pannus progression can be fatal especially if left untreated.¹² MRI can detect a pannus and may be helpful for planning surgery.¹³ Surgical resection has been the treatment of choice for patients with neurologic symptoms.¹⁴ However, some cases have reported resolution of pannus associated with RA and other forms of chronic atlantoaxial instability only after posterior stabilization.¹⁴In order to manage pannus, cervical spine examination for the diagnosis of cervical involvement is encouraged to prevent morbidity and mortality.¹³ There are new data that demonstrated the potential of using retinoid X receptor agonists, such as bexarotene, as a treatment against the development and progression of pannus.¹⁴

Conclusions

We present a patient with cervical pannus disease without RA whose diagnosis was based on the pathognomonic pattern seen on MRI. She showed a clinically significant recovery with an occiput to C2 posterior instrument arthrodesis as well as decompression. She showed marked improvements in her headaches and unsteady gait. This case report highlights the importance of realizing cervical pannus as a disease found in patients without RA. It serves as an alert to clinicians for timely detection, diagnosis, and initiation of treatment to prevent mortality and long-term neurologic sequelae of cervical pannus.

Although further studies of early diagnosis and treatment for cervical pannus are warranted, we propose that including pannus in a differential diagnosis for patients with no RA could be lifesaving.

She showed some improvement in her headaches and unsteady gait. A postoperative pathologic evaluation of tissue was not available. She was referred to a rheumatologist to rule out an autoimmune disease as the cause for this pannus, but no autoimmune disease was found.

Discussion

Cervical pannus is relatively uncommon in those without RA. However, there are multiple reasons that a patient could develop a cervical pannus. Cervical pannus in RA and cervical pannus without RA may mimic each other clinically, but medical management is distinctly different. Consequently, a rheumatology consult is necessary to ensure that there is no undiagnosed autoimmune disorder. Our patient did not have RA, and a neurosurgery intervention was needed to manage her headaches and unsteady gait. Although we could not isolate a cause of this patient’s cervical pannus development, we believed that nonintervention would adversely affect this patient.

The course of pannus progression can be fatal especially if left untreated.¹² MRI can detect a pannus and may be helpful for planning surgery.¹³ Surgical resection has been the treatment of choice for patients with neurologic symptoms.¹⁴ However, some cases have reported resolution of pannus associated with RA and other forms of chronic atlantoaxial instability only after posterior stabilization.¹⁴In order to manage pannus, cervical spine examination for the diagnosis of cervical involvement is encouraged to prevent morbidity and mortality.¹³ There are new data that demonstrated the potential of using retinoid X receptor agonists, such as bexarotene, as a treatment against the development and progression of pannus.¹⁴

Conclusions

We present a patient with cervical pannus disease without RA whose diagnosis was based on the pathognomonic pattern seen on MRI. She showed a clinically significant recovery with an occiput to C2 posterior instrument arthrodesis as well as decompression. She showed marked improvements in her headaches and unsteady gait. This case report highlights the importance of realizing cervical pannus as a disease found in patients without RA. It serves as an alert to clinicians for timely detection, diagnosis, and initiation of treatment to prevent mortality and long-term neurologic sequelae of cervical pannus.

Although further studies of early diagnosis and treatment for cervical pannus are warranted, we propose that including pannus in a differential diagnosis for patients with no RA could be lifesaving.

Patients with gynecologic malignancies who consumed only water for 24 hours before and 24 hours after each chemotherapy cycle had fewer dose delays and reductions compared with patients who didn’t fast, results of a small study showed.

The study included 23 women with ovarian, uterine, or cervical cancer, most of whom received platinum-based chemotherapy and taxanes. Fewer treatment modifications were required among the 11 patients randomized to a 24-hour water-only fast before and after each chemotherapy cycle than among the 12 patients randomized to standard care. Furthermore, there were no hospital admissions in the fasting group and two admissions in the control group, according to study author Courtney J. Riedinger, MD, of the University of Tennessee Medical Center in Knoxville.

She and her colleagues detailed the rationale and results of this study in an abstract that had been slated for presentation at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer. The meeting was canceled because of the COVID-19 pandemic. Data have been updated from the abstract.
 

Rationale

“There’s a lot of new research and interest about nonpharmacologic interventions and lifestyle modifications to help patients cope with chemotherapy and even help with treatment, potentially,” Dr. Riedinger said in an interview.

“We decided to test water-only fasting because there’s not much data about the cell-fitness effects of fasting” on chemotherapy outcomes, she said.

Pre-chemotherapy fasting is based on the concept of differential stress resistance intended to protect normal cells but not cancer cells from the effects of chemotherapy. Fasting decreases levels of insulin-like growth factor 1, which leads healthy cells to enter a protective state by decreasing cell growth and proliferation. Cancer cells, in contrast, cannot enter the protective state, and are therefore more vulnerable than healthy, quiescent cells when exposed to drugs that target the cell cycle, Dr. Riedinger and colleagues noted.

The team cited two studies suggesting a benefit from fasting prior to chemotherapy. In the first study, mice that underwent 48-60 hours of short-term fasting were significantly less likely to die after exposure to a high dose of etoposide, compared with mice that did not fast before exposure (PNAS; 105[24]: 8215-822).

The second study showed that breast and ovarian cancer patients had improved quality of life scores and decreased fatigue when they fasted for 36 hours before and 24 hours after a chemotherapy cycle (BMC Cancer;18: article 476).
 

Study details

Dr. Riedinger and colleagues conducted a nonblinded, randomized trial of fasting in women, aged 34-73 years, who had gynecologic malignancies treated with a planned six cycles of chemotherapy. The patients were instructed to maintain a water-only fast for 24 hours before and 24 hours after each cycle. Controls did not fast.

Patient functional status and quality of life were investigated with the National Comprehensive Cancer Network–Functional Assessment of Cancer Therapy Ovarian Symptom Index (NCCN-FACT FOSI-18). Questionnaires were completed at each chemotherapy visit, and the records were reviewed to evaluate compliance, changes in treatment plan, and hospitalizations.

In all, 92% of chemotherapy cycles were completed with fasting as directed.

There were no significant differences in any of the study measures between patients who fasted and those who did not. However, this study was not powered to detect a difference, according to Dr. Riedinger.

Still, there were trends suggesting a benefit to fasting. Fasting patients had a higher mean change in NCCN-FACT FOSI-18 score compared with controls – increases of 5.11 and .22, respectively.

Five patients in the fasting group required changes to their treatment regimen, compared with eight patients in the control group. In addition, there were no hospital admissions in the fasting group and two admissions in the control group.

Patients tolerated the fast well without significant weight loss, and there were no grade 3 or 4 toxicities among patients who fasted.

The investigators are planning a larger study to further evaluate the effect of fasting on quality of life scores and treatment, and to evaluate the effects of fasting on hematologic toxicities. Future studies will focus on the optimal duration of fasting and the use of fasting-mimicking diets to allow for longer fasting periods, Dr. Riedinger said.

The study was internally funded. The authors reported no conflicts of interest.

Patients taking isotretinoin can use telemedicine to meet with their prescribing physicians instead of in-person visits, and female patients can use at-home pregnancy tests to comply with the requirements of the iPLEDGE program during the COVID-19 pandemic, according to an update program posted on the iPLEDGE website.

Obencem/Thinkstock

The program’s other requirements – the prescription window and two forms of birth control – remain unchanged.

The change follows recent guidance from the Department of Health & Human Services and the Food and Drug Administration regarding accommodations for medical care and drugs subject to Risk Evaluation and Mitigation Strategies (REMS) in the midst of a public health emergency that requires most people to remain in their homes except for essential services.

Allowing females to take at-home pregnancy tests and communicate the results to physician according to their preference is “a game changer for the middle of a pandemic, obviously,” Neil Goldberg, MD, a dermatologist in Westchester County, New York, said in an interview. “These are patients who don’t need to spend time outside just to get pregnancy tests done. It makes it a lot easier.”

Dr. Goldberg is frustrated, however, that the accommodations have not been more widely publicized; he discovered the change incidentally when speaking to an iPLEDGE program representative to request a waiver for a patient who had taken her pregnancy test too early. The program had denied a similar request for a 15-year-old patient of his the previous week, despite the patient being abstinent and having been in shelter-in-place for several weeks.

“The size of your notice [on the website] should be proportionate to how important it is,” Dr. Goldberg said, and the small red box on the site is easy to miss. By contrast, asking anyone to leave their homes to go to a lab for a pregnancy test in the midst of a global pandemic so they can continue their medication would be putting patients at risk, he added.

The iPLEDGE program is designed in part to ensure unplanned pregnancies do not occur in females while taking the teratogenic acne drug. But the rules are onerous and difficult even during normal times, pointed out Hilary Baldwin, MD, medical director of the Acne Treatment and Research Center in New York City and past president of the American Acne and Rosacea Society.

Male patients taking isotretinoin must visit their physician every month to get a new no-refills prescription, but females must get a pregnancy test at a Clinical Laboratory Improvement Amendments–certified lab, which must then provide physical results to the prescribing physician. The doctor enters the negative pregnancy test and the two forms of birth control the patient is taking in the iPLEDGE program site.

Then the patient must take an online test at home to acknowledge they understand what it means to not get pregnant and enter the two forms of birth control they are using – which must match what the doctor enters – before the pharmacy can dispense the drug. The entire process must occur within 7 days or else the patient has to wait 19 days before starting the process over.

“We run a very tight schedule for girls. And every month, we would worry that something would interfere, a snow storm or something else, and that they wouldn’t be able to complete their objectives within the 7-day period,” Dr Baldwin said in an interview. “It was always difficult, and now with us not being able to see the patient and the patient not wanting to go to the lab, this became completely impossible.”

Until this change, some patients may not have been able to get their prescription for severe nodulocystic acne, which can cause physical and psychological scarring, and “postponing treatment increases the likelihood of scarring,” Dr. Baldwin pointed out.

The Food and Drug Administration has updated the labels for peginterferon beta-1a (Plegridy) and interferon beta-1a (Avonex) to include more information about usage of these medications during pregnancy and breastfeeding in women with multiple sclerosis (MS).

The FDA based the decision on data from more than 1,000 real-world pregnancies, including pregnancies from a large epidemiologic study and published studies over several decades, which found no connection between use of interferon-beta products during early pregnancy and an increased risk of major birth defects, according to the FDA.

As a result, the labels for both medications will no longer have the pregnancy category C designation; however, patients should continue to notify their health care provider if they are pregnant or plan to become pregnant.

The FDA decision to remove the warning follows a similar decision by the European Medicines Agency last year.

“Many women with MS are diagnosed during their childbearing years. With this important update for Plegridy and Avonex, healthcare providers have more data to inform appropriate treatment paths for patients who may be pregnant or planning for pregnancy,” said Bernd Kieseier, MD, MHBA, executive director and head of global MS at Worldwide Medical, Biogen, in a press release.
