Sleep: It Does a Body Good by Dr. Nancy Stewart

Sleep: it does a body good. No really, it does. When asked to write this month’s blog on sleep for Sleep Awareness Month, although honored, it was somewhat comical because the night prior I had one of my worst nights of sleep in a long time, taking care of a sick child. As health-care providers, we often lead stressful lives and pack way too much into our schedules. Both the Centers for Disease Control and the American Academy of Sleep Medicine recommend obtaining 7 to 9 hours of sleep per night for adults; unfortunately, many of us are not getting the recommended 7 to 9 hours of sleep.

MILWAUKEE – Congress has allocated a half billion dollars annually to the National Institutes of Health for a program that seeks to end America’s opioid crisis. The agency is putting in place over two-dozen projects spanning basic and translational research, clinical trials, and implementation of new strategies to address pain and fight addiction.

The Helping to End Addiction Long-term (HEAL) initiative has over $850 million in total obligated for fiscal year 2019, said Walter Koroshetz, MD, speaking at the scientific meeting of the American Pain Society. This represents carryover from 2018, a planning year for the initiative, along with the 2019 $500 million annual supplement to the NIH’s base appropriation.

In 2018, NIH and other federal agencies successfully convinced Congress that funding a coordinated use of resources was necessary to overcome the country’s dual opioid and chronic pain crises. “Luck happens to the prepared,” said Dr. Koroshetz, director of the National Institute of Neurological Disorders and Stroke (NINDS), Bethesda, Md., adding that many hours went into putting together a national pain strategy that is multidisciplinary and multi-layered, and involves multiple players.

The two aims of research under the initiative are to improve treatments for misuse and addiction, and to enhance pain management. Focusing on this latter aim, Dr. Koroshetz said that the initiative has several research priorities to enhance pain management.

First, the biological basis for chronic pain needs to be understood in order to formulate effective therapies and interventions. “We need to understand the transition from acute to chronic pain,” he commented. “We need to see if we can learn about the risk factors for developing chronic pain; if we get really lucky, we might identify some biological markers” that identify who is at risk for this transition “in a high-risk acute pain situation.”

Next, a key request of industry and academia will be development of more drugs that avoid the dual-target program of opioids, which affect reward circuitry along with pain circuitry. “Drugs affecting the pain circuit and the reward circuit will always result in addiction” potential, said Dr. Koroshetz. “We’re still using drugs for pain from the poppy plant that were discovered 8,000 years ago.”

The hope with the HEAL initiative is to bring together academic centers with patient populations and research capabilities with industry, to accelerate moving nonaddictive treatments through to phase 3 trials.

Recently, two studies were published addressing the potential association of childhood cancer and assisted reproductive technology. For more than a decade and a half, it has been acknowledged that ART is associated with increased concern both with structural birth defects, as well as imprinting disorders. As both of these issues have been linked to greater cancer risk in children, it is important to decipher the impact of ART on childhood cancer risk.

Published online April 1 in JAMA Pediatrics, the study, “Association of in vitro fertilization [IVF] with childhood cancer in the United States,”¹ by LG Spector et al. looked retrospectively at birth and cancer registries in 14 states with 8 years of data on 275,686 children were conceived via ART through 2013, who were compared with 2,266,847 children selected randomly.

The overall cancer rate per 1,000,000 person-years was low in both groups: 252 for the IVF group and 193 for the control group, for an overall hazard risk of 1.17. Of note, the rate of hepatic tumors was higher among the IVF group than the non-IVF group (18 vs. 5.7; hazard ratio, 2.46). There appeared to be no association with specific IVF treatments, whether children were conceived by donor egg vs. autologous egg; frozen embryos vs. fresh embryos; use of intracytoplasmic sperm injection (ICSI) vs. none; assisted hatching vs. none; and day-3 vs. day-5 transfer. The researchers concluded that the “increased rate of embryonal cancers, particularly hepatic tumors, that could not be attributed to IVF rather than to underlying infertility.”

This first and largest cohort study of association between IVF and the risk of childhood cancer ever published showed little evidence of excess risk of most cancers, including more common cancers such as leukemia.

The authors did note limitations in their study. Mothers who conceived via IVF were more likely to be white, non-Hispanic, more educated, and older. Could this patient population undergoing ART be at greater risk of producing offspring with cancer concerns? If that were the case – and not great risk of childhood cancer in ART, per se – one therefore would extrapolate that couples undergoing ART vs. alternative infertility treatment should not show a treatment-biased risk (i.e., ART vs. non-ART).

This was demonstrated recently in the study, “Risk of cancer in children and young adults conceived by assisted reproductive technology.”² This Dutch historical cohort study with prospective follow-up of a median 21 years evaluated 47,690 live-born children, of which 24,269 were ART conceived, 13,761 naturally conceived, and 9,660 conceived naturally or with fertility drugs but not by ART.

Overall, cancer risk was not increased in ART-conceived children, compared with naturally conceived subfertile women or even the general population. A nonsignificant increased risk was observed in children conceived by ICSI or cryopreservation.

On the basis of these two studies, there appears to be no significant increased risk of cancer in children conceived through fertility treatment, including ART.

Although these studies do not support the conclusion reached by a 2013 meta-analysis of 9 studies that specifically looked at ART and 16 other studies that looked at other types of medically assisted reproduction (such medically assisted reproduction as reproduction achieved through ovulation induction; controlled ovarian stimulation; ovulation triggering; intrauterine, intracervical, or intravaginal insemination) which reported a significant increased risk of overall cancers (1.33), including leukemia, CNS cancer, and neuroblastoma,³ they do agree more closely with two prospective studies conducted in the United Kingdom and Nordic countries.

In the U.K. study,⁴ there was no overall increased risk of cancer associated with ART, but two types of cancer were noted to be higher in the ART-conceived group – hepatoblastoma (3.27 risk) and rhabdomyosarcoma (2.62 risk) – but the absolute risk of these two types of cancer was small in this 17-year study of 106,013 children. This, of course, would be consistent with the JAMA Pediatrics study. In the Nordic study,⁵ similar to the Dutch Study, IVF was not associated with a significant increased risk of cancer (1.08). The Nordic study included 91,796 children born of ART-assisted pregnancies, compared with 358,419 children born after spontaneous conceptions.

The evidence so far shows that there appears to be no significant increased risk of cancer overall associated with fertility treatments, including IVF.

Dovato (dolutegravir and lamivudine), a product of ViiV Healthcare, is intended to serve “as a complete regimen” for the treatment of HIV-1 infection in adults who have had no previous antiretroviral treatment and who have an infection with no known or suspected genetic substitutions associated with resistance to the individual components of Dovato.

“With this approval, patients who have never been treated have the option of taking a two-drug regimen in a single tablet while eliminating additional toxicity and potential drug interactions from a third drug,” said Debra Birnkrant, MD, director of the FDA’s Division of Antiviral Products.

The Dovato labeling includes a Boxed Warning that patients infected with both HIV and hepatitis B should add additional treatment for their HBV or consider a different drug regimen. The most common adverse reactions with Dovato were headache, diarrhea, nausea, insomnia, and fatigue. In addition, the FDA warned that, as there is a known risk for neural tube defects with dolutegravir, patients are advised to avoid use of Dovato at the time of conception through the first trimester of pregnancy.

Clinicians should offer biennial mammography to screen for breast cancer in asymptomatic average-risk women aged 50-74 years and should abandon clinical breast examinations (CBE) for screening in such women of any age, according to a new guideline from the American College of Physicians.

Catherine Yeulet/Thinkstock

Further, clinicians should discuss whether to screen with mammography in average-risk women aged 40-49 years and consider potential harms and benefits, as well as patient preferences. Providers should discontinue screening average-risk women at age 75 years and women with a life expectancy of 10 years or less, Amir Qaseem, MD, PhD, of the ACP and colleagues wrote on behalf of the ACP Clinical Guidelines Committee.

The ACP guidance also addresses the varying recommendations from other organizations on the age at which to start and stop screening and on screening intervals, noting that “areas of disagreement include screening in women aged 40 to 49 years, screening in women aged 75 years or older, and recommended screening intervals,” and stresses the importance of patient input.

“Women should be informed participants in personalized decisions about breast cancer screening,” the authors wrote, adding that those under age 50 years without a clear preference for screening should not be screened.

However, the evidence shows that most average-risk women with no symptoms will benefit from mammography every other year beginning at age 50 years, they said.

The statement, published online April 8 in the Annals of Internal Medicine, was derived from a review of seven existing English-language breast cancer screening guidelines and the evidence cited in those guidelines. It’s intended to be a resource for all clinicians.

It differs from the 2017 American College of Obstetricians and Gynecologists (ACOG) guidelines in that ACOG recommends CBE and does not address screening in those with a life expectancy of less than 10 years. It also differs from the 2016 U.S. Preventive Services Task Force (USPSTF) guidelines, which make no recommendation on CBE and also do not address screening in those with a life expectancy of less than 10 years.

Other guidelines, such as those from the American College of Radiology, American Cancer Society (ACS), the Canadian Task Force on Preventive Health Care, and the National Comprehensive Cancer Network, recommend CBE, and the World Health Organization guidelines recommend CBE in low resource settings.

“Although CBE continues to be used as part of the examination of symptomatic women, data are sparse on screening asymptomatic women using CBE alone or combined with mammography,” the ACP guideline authors wrote. “The ACS recommends against CBE in average-risk women of any age because of the lack of demonstrated benefit and the potential for false-positive results.”

The guidance, which does not apply to patients with prior abnormal screening results or those at higher breast cancer risk, also includes an evidence-driven “talking points with patients” section based on frequently asked questions.

An important goal of the ACP Clinical Guidelines Committee in developing the guidance is to reduce overdiagnosis and overtreatment, which affects about 20% of women diagnosed over a 10-year period.

The committee reviewed all national guidelines published in English between January 1, 2013, and November 15, 2017, in the National Guideline Clearinghouse or Guidelines International Network library, and it also selected other guidelines commonly used in clinical practice. The committee evaluated the quality of each by using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument.

Alex Krist, MD, the USPSTF vice-chairperson, offered support for the “shift toward shared decision making that is emerging” and added it’s “part of a larger movement toward empowering people with information not only about the potential benefits but also the potential harms of screening tests.”

“In its 2016 recommendation, the Task Force found that the value of mammography increases with age, with women ages 50-74 benefiting most from screening. For women in their 40s, the Task Force also found that mammography screening every two years can be effective,” he told this publication. “We recommend that the decision to start screening should be an individual one, taking into account a woman’s health history, preferences, and how she values the different potential benefits and harms.”

Dr. Krist further noted that the USPSTF, ACP, and many others “have all affirmed that mammography is an important tool to reduce breast cancer mortality and that the benefits of mammography increase with age.”

Likewise, Robert Smith, PhD, vice president of cancer screening for the ACS, noted that the ACP guidance generally aligns with ACS and USPSTF guidelines because all “support informed decision making starting at age 40, and screening every two years starting at age 50 (USPSTF) or 55 (ACS).”

“The fact that all guidelines are not totally in sync is not unexpected. ... The most important thing to recognize is that all of these guidelines stress that regular mammography plays an important role in breast cancer early detection, and women should be aware of its benefits and limitations, and also remain vigilant and report any breast changes,” he said.

The guidance authors reported having no conflicts of interest.

A small study offers a tantalizing hint that the gout drug colchicine could help reduce inflammation-related complications of metabolic syndrome.

The 3-month trial did not meet its primary endpoint – change in insulin sensitivity as measured by a glucose tolerance test – but it did hit several secondary goals, all of which were related to the inflammation that accompanies prediabetes, Jack A. Yanovski, MD, and colleagues wrote in Diabetes, Obesity, and Metabolism.

“Colchicine is well-known to have anti-inflammatory properties, although its effect on obesity-associated inflammation has not previously been investigated,” said Dr. Yanovski of the National institutes of Health and his coauthors. “Classically, it has been posited that colchicine blocks inflammation by impeding leukocyte locomotion, diapedesis, and, ultimately, recruitment to sites of inflammation. ... Recently, it has been shown that colchicine also inhibits the formation of the NLRP3 [NOD-like receptor family pyrin domain-containing 3] inflammasome, an important component of the obesity-associated inflammatory cascade.”

The NLRP3 inflammasome has been shown to play an important part in promoting the inflammatory state of obesity, the authors noted. When a cell senses danger, NLRP3 uses microtubules to create an inflammasome that then produces interleukin-1 beta gene and interleukin-18. One of colchicine’s known actions is to inhibit microtubule formation, suggesting that it could put the brakes on this process.

The study comprised 40 patients who had metabolic syndrome, significant insulin resistance, and elevated inflammatory markers. Among the exclusionary criteria were having a significant medical illness, a history of gout, and recent or current use of colchicine.

The patients were randomized to colchicine 0.6 mg or placebo twice daily for 3 months. No dietary advice was given during the study period. Of the 40 randomized patients, 37 completed the 3-month study, though none left because of adverse events.

Although there were no significant between-group differences in levels of fasting insulin, colchicine did significantly decrease inflammatory markers, compared with placebo. C-reactive protein dropped by 2.8 mg/L in the active group but increased slightly in the placebo group. The erythrocyte sedimentation rate also decreased in the colchicine group, compared with placebo (difference, –5.9 mm/hr; P = .07). The active group experienced an improvement in fasting insulin as measured by the homeostasis model assessment–estimated insulin resistance index and in glucose effectiveness, which suggests metabolic improvement.

“Larger trials are needed to investigate whether colchicine has efficacy in improving insulin resistance and/or preventing the onset of diabetes mellitus in at-risk individuals with obesity-associated inflammation,” the authors concluded.

The study was supported by the Intramural Research Program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development and by the National Institutes of Health. None of the authors reported any disclosures or conflicts of interest relating to this study.

The Diagnosis: Juvenile Dermatomyositis 

Juvenile dermatomyositis (JDM) is a rare idiopathic inflammatory myopathy of childhood that is autoimmune in nature with an annual incidence ranging from 2.5 to 4.1 cases per million children. Its peak incidence is between 5 and 10 years of age, and it affects girls more than boys at a 2-fold to 5-fold greater rate.¹ Juvenile dermatomyositis is characterized by skeletal muscle weakness in the presence of distinctive rashes, including Gottron papules and heliotrope erythema. Muscle weakness typically is proximal and symmetrical, and eventually patients may have trouble rising from a seated position or lifting objects overhead. Other skin manifestations include nail fold capillary changes, calcinosis cutis, and less commonly ulcerations signifying vasculopathy of the skin.² A subset of patients will present with juvenile amyopathic dermatomyositis. These children have the characteristic skin changes without the muscle weakness or elevated muscle enzymes for more than 6 months; however, one-quarter may go on to develop mysositis.³ 

Diagnosis of JDM traditionally was based on the following 5 diagnostic criteria: characteristic skin rash, proximal muscle weakness, elevated muscle enzymes, myopathic changes on electromyogram, and typical muscle biopsy.¹ Current practice shows a broadening of diagnostic criteria using new techniques in the diagnosis of JDM. To make the diagnosis, the patient must have the characteristic skin manifestations with a minimum of 3 other criteria.⁴ A 2006 international consensus survey expanded the list of criteria to include typical findings on magnetic resonance imaging (MRI), nail fold capillaroscopy abnormalities, calcinosis, and
dysphonia.⁵  

To assess muscle disease, MRI is utilized because it is a reliable noninvasive tool to assess muscle inflammation. Muscle biopsy is only recommended if the diagnosis is unclear.⁵ The results of the MRI in our patient displayed symmetric mild fatty atrophy of the gluteus maximus muscle, as well as edema in the right rectus femoris and left vastus lateralis muscles, suggesting early findings of myositis. Muscle enzymes may not be diagnostic because  they are not always elevated at diagnosis. Our patient had a normal creatinine kinase level (92 U/L [reference range, <190 U/L]), and both aldolase and lactate dehydrogenase also were within reference range. Conversely, antinuclear antibodies frequently are positive in patients with JDM, such as in our patient at a 1:320 dilution, but are nonspecific and nondiagnostic. It is recommended to include nail fold capillaroscopy to evaluate periungual capillary changes because nailfold capillary density is a sensitive measure of both skin and muscle disease.⁵ Using dermoscopy, nail fold capillary dilation was observed in our patient. 

Other differential diagnoses can have somewhat similar clinical features to JDM. Infantile papular acrodermatitis, commonly referred to as Gianotti-Crosti syndrome, is a viral exanthem that affects children (median age, 2 years).⁶ The rash appears as monomorphous, flat-topped, pink to brown papules affecting the face, buttocks, and arms; it typically spontaneously resolves in 10 days.⁶ 

Juvenile-onset lupus is a chronic autoimmune disorder that can involve any organ system and typically affects children aged 11 to 12 years with a female preponderance. Skin manifestations are similar to adult-onset lupus and include malar rash, discoid rash, oral ulcerations, petechiae, palpable purpura, and digital telangiectasia and ulcers. ⁷ 

Juvenile scleroderma is rare connective-tissue disorder that also has multiple organ involvement. Cutaneous involvement can range from isolated morphealike plaques to diffuse sclerotic lesions with growth disturbances, contractures, and facial atrophy.⁸ 

Verrucae planae, commonly referred to as flat warts, are papules caused primarily by human papillomavirus types 3, 10, 28, and 41. Children and young adults commonly are affected, and warts can appear on the hands, as in our patient.⁶ 

Treatment of JDM depends on disease severity at initial presentation and requires a multidisciplinary approach. The mainstay of treatment is high-dose oral prednisone in combination with disease-modifying drugs such as methotrexate and cyclosporin A. Patients with more severe presentations (eg, ulcerative skin disease) or life-threatening organ involvement are treated with cyclophosphamide, usually in combination with high-dose glucocorticoids.⁹ 

Early detection with aggressive treatment is vital to reduce morbidity and mortality from organ damage and disease complications. Mortality rates have dropped to 3%¹⁰ in recent decades with the use of systemic glucocorticoids. Delayed treatment is associated with a prolonged disease course and poorer outcomes. Disease complications in children with JDM include osteoporosis, calcinosis, and intestinal perforation; however, with early treatment, children with JDM can expect full recovery and to live a normal life as compared to adults with dermatomyositis.¹⁰ 

Prior to our patient's diagnosis, the family was assigned to move to an overseas location through the US Military with no direct access to advanced medical care. Early detection and diagnosis of JDM through an astute clinical examination allowed the patient and her family to remain in the continental United States to continue receiving specialty care.

Our patient had a normal creatinine kinase level (92 U/L [reference range, <190 U/L]), and both aldolase and lactate dehydrogenase also were within reference range. Conversely, antinuclear antibodies frequently are positive in patients with JDM, such as in our patient at a 1:320 dilution, but are nonspecific and nondiagnostic. It is recommended to include nail fold capillaroscopy to evaluate periungual capillary changes because nailfold capillary density is a sensitive measure of both skin and muscle disease.⁵ Using dermoscopy, nail fold capillary dilation was observed in our patient. 

Other differential diagnoses can have somewhat similar clinical features to JDM. Infantile papular acrodermatitis, commonly referred to as Gianotti-Crosti syndrome, is a viral exanthem that affects children (median age, 2 years).⁶ The rash appears as monomorphous, flat-topped, pink to brown papules affecting the face, buttocks, and arms; it typically spontaneously resolves in 10 days.⁶ 

Juvenile-onset lupus is a chronic autoimmune disorder that can involve any organ system and typically affects children aged 11 to 12 years with a female preponderance. Skin manifestations are similar to adult-onset lupus and include malar rash, discoid rash, oral ulcerations, petechiae, palpable purpura, and digital telangiectasia and ulcers. ⁷ 

Juvenile scleroderma is rare connective-tissue disorder that also has multiple organ involvement. Cutaneous involvement can range from isolated morphealike plaques to diffuse sclerotic lesions with growth disturbances, contractures, and facial atrophy.⁸ 

Verrucae planae, commonly referred to as flat warts, are papules caused primarily by human papillomavirus types 3, 10, 28, and 41. Children and young adults commonly are affected, and warts can appear on the hands, as in our patient.⁶ 

Treatment of JDM depends on disease severity at initial presentation and requires a multidisciplinary approach. The mainstay of treatment is high-dose oral prednisone in combination with disease-modifying drugs such as methotrexate and cyclosporin A. Patients with more severe presentations (eg, ulcerative skin disease) or life-threatening organ involvement are treated with cyclophosphamide, usually in combination with high-dose glucocorticoids.⁹ 

Early detection with aggressive treatment is vital to reduce morbidity and mortality from organ damage and disease complications. Mortality rates have dropped to 3%¹⁰ in recent decades with the use of systemic glucocorticoids. Delayed treatment is associated with a prolonged disease course and poorer outcomes. Disease complications in children with JDM include osteoporosis, calcinosis, and intestinal perforation; however, with early treatment, children with JDM can expect full recovery and to live a normal life as compared to adults with dermatomyositis.¹⁰ 

Prior to our patient's diagnosis, the family was assigned to move to an overseas location through the US Military with no direct access to advanced medical care. Early detection and diagnosis of JDM through an astute clinical examination allowed the patient and her family to remain in the continental United States to continue receiving specialty care.   
 

The Diagnosis: Juvenile Dermatomyositis 

Juvenile dermatomyositis (JDM) is a rare idiopathic inflammatory myopathy of childhood that is autoimmune in nature with an annual incidence ranging from 2.5 to 4.1 cases per million children. Its peak incidence is between 5 and 10 years of age, and it affects girls more than boys at a 2-fold to 5-fold greater rate.¹ Juvenile dermatomyositis is characterized by skeletal muscle weakness in the presence of distinctive rashes, including Gottron papules and heliotrope erythema. Muscle weakness typically is proximal and symmetrical, and eventually patients may have trouble rising from a seated position or lifting objects overhead. Other skin manifestations include nail fold capillary changes, calcinosis cutis, and less commonly ulcerations signifying vasculopathy of the skin.² A subset of patients will present with juvenile amyopathic dermatomyositis. These children have the characteristic skin changes without the muscle weakness or elevated muscle enzymes for more than 6 months; however, one-quarter may go on to develop mysositis.³ 

Diagnosis of JDM traditionally was based on the following 5 diagnostic criteria: characteristic skin rash, proximal muscle weakness, elevated muscle enzymes, myopathic changes on electromyogram, and typical muscle biopsy.¹ Current practice shows a broadening of diagnostic criteria using new techniques in the diagnosis of JDM. To make the diagnosis, the patient must have the characteristic skin manifestations with a minimum of 3 other criteria.⁴ A 2006 international consensus survey expanded the list of criteria to include typical findings on magnetic resonance imaging (MRI), nail fold capillaroscopy abnormalities, calcinosis, and
dysphonia.⁵  

To assess muscle disease, MRI is utilized because it is a reliable noninvasive tool to assess muscle inflammation. Muscle biopsy is only recommended if the diagnosis is unclear.⁵ The results of the MRI in our patient displayed symmetric mild fatty atrophy of the gluteus maximus muscle, as well as edema in the right rectus femoris and left vastus lateralis muscles, suggesting early findings of myositis.
