New Recommendations for Transitioning Youths With Brain Disorders to Adult Care
A new consensus statement provides recommendations for transitioning adolescents and young adults with neurologic disorders to adult care. Created by the Child Neurology Foundation, the recommendations were published online ahead of print July 27 in Neurology.
"The goal of this research is to help make the transition easier for millions of parents and caregivers of children who are reaching the age where they will be dealing with complex teenage and adult life situations," said study author Lawrence W. Brown, MD, a pediatric neurologist at the Children's Hospital of Philadelphia.
The consensus statement is the work of the Neurology Transition Consensus Panel, an interdisciplinary team including child neurologists, child neurology nurses, adult neurologists, rehabilitation specialists, patients, and family members of neurology patients.
The research team reviewed studies published within the last 10 years focused mainly on transition of care for those with neurologic disorders. Older studies and book chapters that were relevant to transition in general were also included. The consensus statement addresses the great majority of adolescents and young adults whose care shifts from pediatric to adult providers. The paper does not directly address children with brain diseases who are not expected to live to adulthood or those children who are managed by adult neurologists. However, it strongly recommends that adult models of care be introduced even if providers are unchanged.
The consensus statement identifies the following eight best practices for making the transition from pediatric to adult care as smooth as possible:
· Expectation of future transition to the adult care system with the youth and family is discussed before age 13.
· Self-management skills should be assessed at age 12 and reevaluated on a yearly basis.
· Yearly transition planning sessions should also address the youth's medical condition, including current medications and potential side effects; signs and symptoms of concern; genetic counseling and reproductive implications of the condition; issues of puberty and sexuality; driving, alcohol, substance use, and other risks; and emotional or psychological concerns and wellness.
· If appropriate, a discussion with the caregivers regarding the youth's expected legal competency (ie, whether there is a need for legal guardianship and powers of attorney) should begin by age 14. If the youth's expected legal competency is unclear, assessment of that capacity should be made yearly.
· A comprehensive transition plan should be developed by age 14 in collaboration with the youth, caregivers, other health care providers, school personnel, vocational professionals, community services providers, and legal services regarding all aspects of health, financial, and legal care. This is usually the responsibility of the primary care provider.
· The child neurology team is responsible for the neurologic component of the comprehensive transition plan and should update it annually.
· Adult providers are identified in collaboration with the youth and caregivers prior to the anticipated time of transfer. A medical transfer packet is prepared for the adult provider and provided to the youth; it includes the transition plan and medical summary with pertinent history, diagnostic evaluations, previous drug trials, current medications, and protocol for emergency care.
· The child neurology team communicates directly with the new adult provider to ensure smooth completion of the transition process, which is finalized after the first appointment. It is recommended that the child neurologist be available to the youth and the adult provider for continuity and support.
"We believe that following these steps will make a real difference in the lives of our patients as they become independent and self-sufficient adults to the greatest extent possible," said Dr. Brown.
The consensus statement was endorsed by the American Academy of Neurology, the Child Neurology Society, and the American Academy of Pediatrics and was cosponsored by Eisai.

Painful Ulcerations Above the Malleoli
The Diagnosis: Livedoid Vasculopathy
Livedoid vasculopathy (LV) is a rare cutaneous disorder that most commonly affects the lower legs. It has an estimated incidence of 1 case per 100,000 per year and predominantly affects women.1 The disease pathogenesis is not fully understood but is thought to involve thrombosis and occlusion of dermal vessels resulting in tissue hypoxia.2 Both inherited and acquired thrombophilic conditions frequently are seen in patients with LV.3,4 Livedoid vasculopathy also has been described as idiopathic5 and is associated with immune complex deposition.6 However, the number of cases of idiopathic LV may be overestimated; as technological advancements to detect coagulation abnormalities improve, it is hypothesized that this entity will be identified less often.2,4
Livedoid vasculopathy has been described in the literature using the term PPURPLE (painful purpuric ulcers with reticular pattern of lower extremities).7 The triad of livedo racemosa, recurrent painful ulcerations, and residual healing with atrophie blanche characterizes the clinical manifestations of LV; however, all 3 characteristics do not need to appear simultaneously for a diagnosis to be made. The condition has a chronic course with spontaneous remissions and exacerbations. Episodic ulcerations occur, especially in the summertime, and heal slowly, leaving behind atrophic, porcelain white, stellate-shaped scars called atrophie blanche. Livedo racemosa also may be seen in Sneddon syndrome; however, these patients experience neurologic symptoms secondary to cerebrovascular occlusion. In contrast to livedo racemosa, acquired livedo reticularis represents a physiologic hypoperfusion pattern that occurs in response to cold exposure.8 A localized sharp pain, known as angina cutis, typically precedes the clinical symptom of painful ulcerations.9 Atrophie blanche once was thought to be specific to LV but has been seen in other diseases such as systemic lupus erythematosus and chronic venous insufficiency.2
The diagnosis of LV is based on identification of characteristic clinical features and skin biopsy. In almost all biopsy specimens, histopathology reveals fibrinoid occlusion of vessels in the superficial and mid dermis.4 Other findings may include epidermal necrosis and vessel wall hyalinization and infarction2 (Figure). Because LV is commonly misdiagnosed as vasculitis, the absence of hallmark features of vasculitis such as neutrophilic infiltrate of blood vessel walls and fibrinoid necrosis suggest the diagnosis. Extensive laboratory evaluation for inherited and acquired coagulation abnormalities should be performed.
Treatment of LV is difficult, as there is currently no consensus on optimal therapy. The mainstay of therapy is to reduce pain, prevent infection, and reduce ulceration and development of atrophie blanche. Underlying causes should be identified and appropriately treated. Because the primary pathogenesis of LV is considered to be a hypercoagulable state, first-line treatment often includes therapies to enhance blood flow and prevent thrombosis such as smoking cessation, antiplatelet therapy, and pentoxifylline. Vasodilating agents, anti-inflammatory agents, anticoagulation, and fibrinolytic therapy also have been used with varying degrees of success.7

A 58-year-old woman presented in the summertime with skin discoloration of the bilateral lower legs and painful ulcerations above the medial and lateral malleoli of 15 years’ duration. She denied any recent trauma to the area or change in skin lesion appearance with cold exposure. Extensive laboratory evaluation for inherited and acquired coagulation abnormalities was negative. A punch biopsy specimen obtained from the left anterior lower leg revealed vascular thrombi with extravasated erythrocytes and a sparse perivascular inflammatory cell infiltrate.
Enlarging Breast Lesion
The Diagnosis: Radiation-Associated Angiosarcoma
At the time of presentation, a 4-mm lesional punch biopsy was obtained (Figure), which revealed an epithelioid neoplasm within the dermis expressing CD31 and CD34, and staining negatively for S-100, CD45, and estrogen and progesterone receptors. The histologic and immunophenotypic findings were compatible with the diagnosis of angiosarcoma. Given the patient’s history of radiation for breast carcinoma several years ago, this tumor was consistent with radiation-associated angiosarcoma (RAAS).
Development of secondary angiosarcoma has been linked to both prior radiation (RAAS) and chronic lymphedema (Stewart-Treves syndrome).1 Radiation-associated angiosarcoma is defined as a “pathologically confirmed breast or chest wall angiosarcoma arising within a previously irradiated field.”2 The incidence of RAAS is estimated to be 0.9 per 1000 individuals following radiation treatment of breast cancer over the subsequent 15 years and a mean time from radiation to development of 7 years.1 Incidence is expected to increase in the future due to improved likelihood of surviving early-stage breast carcinoma and the increased use of external beam radiation therapy for management of breast cancer.
Differentiating between primary and secondary angiosarcoma of the breast is important. Although primary breast angiosarcoma usually arises in women aged 30 to 40 years, RAAS tends to arise in older women (mean age, 68 years) and is seen only in those women with prior radiation.2 Additionally, high-level amplification of MYC, a known photo-oncogene, on chromosome 8 is a key genetic alteration of RAAS that helps to distinguish it from primary angiosarcoma, though this variance may be present in only half of RAAS cases.3 Immunohistochemical analysis of tumor cells for MYC expression correlates well with this amplification and also is helpful in distinguishing atypical vascular lesions from RAAS.4 Atypical vascular lesions, similar to RAAS, occur years after radiation exposure and may have a similar clinical presentation. Atypical vascular lesions do not progress to angiosarcoma in reported cases, but clinical and histologic overlap with RAAS make the diagnosis difficult.5 In these cases, analysis with fluorescence in situ hybridization or immunohistochemistry for the MYC amplification is important to differentiate these tumors.6
At the time of presentation, the majority of patients with RAAS of the breast have localized disease, often with a variable presentation. In all known cases, there have been skin changes present, emphasizing the importance of both patient and clinician vigilance on a regular basis in at-risk individuals. In one study, the most common presentation was breast ecchymosis, which was observed in 55% of patients.7 These lesions involve the dermis and are commonly mistaken for benign conditions such as infection or hemorrhage.2 In 2 other studies, RAAS most often manifested as a skin nodule or apparent tumor, closely followed by either a rash or bruiselike presentation.1,2
The overall recommendation for management of patients with ecchymotic skin lesions in previously irradiated regions is to obtain a biopsy specimen for tissue diagnosis. Although there is no standard of care for the management of RAAS, a multidisciplinary approach involving specialists from oncology, surgical oncology, and radiation oncology is recommended. Most often, radical surgery encompassing both the breast parenchyma and the at-risk radiated skin is performed. Extensive surgery has demonstrated the best survival benefits compared to mastectomy alone.7 Chemotherapeutics also may be used as adjuncts to surgery, which have been determined to decrease local recurrence rates but have no proven survival benefits.2 Adverse prognostic factors for survival are tumor size greater than 10 cm and development of local and/or distant metastases.2 Following the diagnosis of RAAS, our patient underwent radical mastectomy with adjuvant chemotherapy and remained disease free 6 months after surgery.
In summary, RAAS is a well-known, albeit relatively uncommon, consequence of radiation therapy. Dermatologists, oncologists, and primary care providers play an important role in recognizing this entity when evaluating patients with ecchymotic lesions as well as nodules or tumors within an irradiated field. Biopsy should be obtained promptly to prevent delay in diagnosis and to expedite referral to appropriate specialists for further evaluation and treatment.

Development of secondary angiosarcoma has been linked to both prior radiation (RAAS) and chronic lymphedema (Stewart-Treves syndrome).1 Radiation-associated angiosarcoma is defined as a “pathologically confirmed breast or chest wall angiosarcoma arising within a previously irradiated field.”2 The incidence of RAAS is estimated to be 0.9 per 1000 individuals following radiation treatment of breast cancer over the subsequent 15 years and a mean time from radiation to development of 7 years.1 Incidence is expected to increase in the future due to improved likelihood of surviving early-stage breast carcinoma and the increased use of external beam radiation therapy for management of breast cancer.
Differentiating between primary and secondary angiosarcoma of the breast is important. Although primary breast angiosarcoma usually arises in women aged 30 to 40 years, RAAS tends to arise in older women (mean age, 68 years) and is seen only in those women with prior radiation.2 Additionally, high-level amplification of MYC, a known photo-oncogene, on chromosome 8 is a key genetic alteration of RAAS that helps to distinguish it from primary angiosarcoma, though this variance may be present in only half of RAAS cases.3 Immunohistochemical analysis of tumor cells for MYC expression correlates well with this amplification and also is helpful in distinguishing atypical vascular lesions from RAAS.4 Atypical vascular lesions, similar to RAAS, occur years after radiation exposure and may have a similar clinical presentation. Atypical vascular lesions do not progress to angiosarcoma in reported cases, but clinical and histologic overlap with RAAS make the diagnosis difficult.5 In these cases, analysis with fluorescence in situ hybridization or immunohistochemistry for the MYC amplification is important to differentiate these tumors.6
At the time of presentation, the majority of patients with RAAS of the breast have localized disease, often with a variable presentation. In all known cases, there have been skin changes present, emphasizing the importance of both patient and clinician vigilance on a regular basis in at-risk individuals. In one study, the most common presentation was breast ecchymosis, which was observed in 55% of patients.7 These lesions involve the dermis and are commonly mistaken for benign conditions such as infection or hemorrhage.2 In 2 other studies, RAAS most often manifested as a skin nodule or apparent tumor, closely followed by either a rash or bruiselike presentation.1,2
The overall recommendation for management of patients with ecchymotic skin lesions in previously irradiated regions is to obtain a biopsy specimen for tissue diagnosis. Although there is no standard of care for the management of RAAS, a multidisciplinary approach involving specialists from oncology, surgical oncology, and radiation oncology is recommended. Most often, radical surgery encompassing both the breast parenchyma and the at-risk radiated skin is performed. Extensive surgery has demonstrated the best survival benefits compared to mastectomy alone.7 Chemotherapeutics also may be used as adjuncts to surgery, which have been determined to decrease local recurrence rates but have no proven survival benefits.2 Adverse prognostic factors for survival are tumor size greater than 10 cm and development of local and/or distant metastases.2 Following the diagnosis of RAAS, our patient underwent radical mastectomy with adjuvant chemotherapy and remained disease free 6 months after surgery.
In summary, RAAS is a well-known, albeit relatively uncommon, consequence of radiation therapy. Dermatologists, oncologists, and primary care providers play an important role in recognizing this entity when evaluating patients with ecchymotic lesions as well as nodules or tumors within an irradiated field. Biopsy should be obtained promptly to prevent delay in diagnosis and to expedite referral to appropriate specialists for further evaluation and treatment.
The Diagnosis: Radiation-Associated Angiosarcoma
At the time of presentation, a 4-mm lesional punch biopsy was obtained (Figure), which revealed an epithelioid neoplasm within the dermis expressing CD31 and CD34, and staining negatively for S-100, CD45, and estrogen and progesterone receptors. The histologic and immunophenotypic findings were compatible with the diagnosis of angiosarcoma.

Patients Concerned about Hospitalist Service Handovers
Background: Service handovers contribute to discontinuity of care in hospitalized patients. Research on hospitalist service handovers is limited, and no previous study has examined the service handover from the patient’s perspective.
Study design: Interview-based, qualitative analysis.
Setting: Urban academic medical center.
Synopsis: Researchers interviewed 40 hospitalized patients using a semi-structured nine-question interview regarding their attending hospitalist service change. The constant comparative method was used to identify recurrent themes in patient responses. The research team identified six themes representative of patient concerns during service change: physician-patient communication, transparency in communication, hospitalist-specialist communication, new opportunities due to transition, bedside manner, and indifference toward the transition.
Authors used the six themes to develop a model for the ideal service handover, utilizing open lines of communication, facilitated by multiple modalities and disciplines, and recognizing the patient’s role as the primary stakeholder in the transition of care.
Bottom line: Incorporating patients’ perspective presents an opportunity to improve communication and efficiency during hospitalist service transitions.

Warfarin Reduces Risk of Ischemic Stroke in High-Risk Patients
Background: For patients with atrial fibrillation and history of intracranial hemorrhage (ICH), the risk of further ICH and the benefit of antithrombotic agents for stroke risk reduction remain unclear.
Study design: Retrospective cohort study.
Setting: National Health Research Institutes, Taiwan.
Synopsis: Using the National Health Insurance Research Database in Taiwan, researchers identified 307,640 patients with atrial fibrillation and a CHA2DS2-VASc score >/= 2. Of this group, 12,917 patients with a history of ICH were identified and separated into three groups: no treatment, antiplatelet treatment, or warfarin. Among the no treatment group, the rate of ICH and ischemic cerebrovascular accident were 4.2 and 5.8 per 100 person-years, respectively. Among patients on antiplatelet therapy, the rates were 5.3% and 5.2%, respectively. Among patients on warfarin, the number needed to treat (NNT) for preventing one ischemic stroke was lower than the number needed to harm (NNH) for producing one ICH among patients with a CHA2DS2-VASc score >/= 6. In patients with lower CHA2DS2-VASc scores, the NNT was higher than NNH.
Bottom line: Treatment with warfarin may benefit patients with atrial fibrillation and prior ICH with CHA2DS2-VASc scores >/= 6, but risk likely outweighs benefit in patients with lower scores.

Identifying and targeting malignant aging in sAML

of California San Diego
Researchers say they have identified RNA-based biomarkers that distinguish normal, aged hematopoietic stem and progenitor cells (HSPCs) from leukemia stem cells (LSCs) associated with secondary acute myeloid leukemia (sAML).
The team believes their discovery may provide a new way to predict leukemic relapse and identify targets for drug development.
Catriona Jamieson, MD, PhD, of the University of California San Diego in La Jolla, and her colleagues described the discovery in Cell Stem Cell.
The researchers noted that age-related hematopoietic stem cell exhaustion and myeloid-lineage skewing promote the transformation of hematopoietic progenitors into therapy-resistant LSCs in sAML. However, the contribution of RNA processing alterations to HSPC aging and LSC generation remains unclear.
With this study, Dr Jamieson and her colleagues discovered RNA splice isoform expression patterns that distinguished normal, aged HSPCs from sAML LSCs.
The team said the aged HSPCs displayed pro-apoptotic BCL2 splice isoform switching, while sAML LSCs favored pro-survival expression of BCL2L1 (BCL-XL).
“These splicing signatures could potentially be used as clinical biomarkers to detect blood stem cells that show signs of early aging or leukemia and to monitor patient responses to treatment,” said study author Leslie Crews, PhD, of the University of California San Diego.
“By being able to distinguish benign from malignant aging based on distinctive RNA splicing patterns, we can develop therapeutic strategies that selectively target leukemia stem cells while sparing normal hematopoietic stem cells,” Dr Jamieson added.
In fact, she and her colleagues were able to show that treatment with a pharmacologic splicing modulator known as 17S-FD-895 could eradicate sAML LSCs while sparing normal HSPCs. The compound reversed pro-survival splice isoform switching and impaired LSC maintenance.
“Our findings show that RNA splicing is a unique therapeutic vulnerability for secondary AML,” Dr Jamieson said. “RNA-splicing-targeted therapies may be a potent and selective way to clear leukemia stem cells and prevent relapse.”

Results of the phase 3 CASTOR trial suggest that adding daratumumab to treatment with bortezomib and dexamethasone can improve progression-free survival (PFS) in patients with previously treated multiple myeloma (MM).
Compared to patients who received only bortezomib and dexamethasone, those who received daratumumab as well had a higher response rate and longer PFS, but they also had a higher incidence of grade 3/4 adverse events (AEs).
These results were recently published in NEJM. They were previously presented at the 2016 ASCO Annual Meeting. The CASTOR trial was funded by Janssen Research & Development.
The trial enrolled 498 patients with relapsed or relapsed and refractory MM. Patients were randomized to receive bortezomib (1.3 mg/m2) and dexamethasone (20 mg) alone (control arm) or in combination with daratumumab (16 mg/kg).
Baseline characteristics were well balanced between the treatment arms. Across both groups, the median patient age was 64 (range, 30 to 88), the median time since MM diagnosis was 3.8 years, and the patients had received a median of 2 (range, 1 to 10) previous lines of therapy.
Efficacy
The overall response rate was significantly higher in the daratumumab arm than the control arm—82.9% and 63.2%, respectively (P<0.001). The rate of complete response or better was higher in the daratumumab arm as well—19.2% and 9.0%, respectively (P=0.001).
After a median follow-up of 7.4 months, the median PFS was not reached in the daratumumab arm and was 7.2 months in the control arm (hazard ratio=0.39, P<0.001). The estimated 12-month PFS was 60.7% and 26.9%, respectively.
Overall survival was not reached in either treatment arm.
This trial was unblinded after meeting its primary endpoint of improved PFS in this interim analysis. Based on the recommendation of an independent data monitoring committee, patients in the control arm were offered the option to receive daratumumab following confirmed disease progression.
Safety
AEs occurred in 98.8% of patients in the daratumumab arm and 95.4% of patients in the control arm. Grade 3/4 AEs occurred in 76.1% and 62.4%, respectively.
There was a higher incidence of the following AEs in the daratumumab arm than the control arm—thrombocytopenia (58.8% vs 43.9%), neutropenia (17.7% vs 9.3%), lymphopenia (13.2% vs 3.8%), peripheral sensory neuropathy (47.3% vs 37.6%), bleeding events (7.0% vs 3.8%), and secondary primary cancers (2.5% vs 0.4%).
Infusion-related reactions associated with daratumumab were reported in 45.3% of patients. These reactions were mostly grade 1 or 2.
The percentage of patients who discontinued treatment because of at least 1 AE was similar between the daratumumab and control arms (7.4% and 9.3%, respectively).

After a median follow-up of 7.4 months, the median PFS was not reached in the daratumumab arm and was 7.2 months in the control arm (hazard ratio=0.39, P<0.001). The estimated 12-month PFS was 60.7% and 26.9%, respectively.
Overall survival was not reached in either treatment arm.
This trial was unblinded after meeting its primary endpoint of improved PFS in this interim analysis. Based on the recommendation of an independent data monitoring committee, patients in the control arm were offered the option to receive daratumumab following confirmed disease progression.
Safety
AEs occurred in 98.8% of patients in the daratumumab arm and 95.4% of patients in the control arm. Grade 3/4 AEs occurred in 76.1% and 62.4%, respectively.
There was a higher incidence of the following AEs in the daratumumab arm than the control arm—thrombocytopenia (58.8% vs 43.9%), neutropenia (17.7% vs 9.3%), lymphopenia (13.2% vs 3.8%), peripheral sensory neuropathy (47.3% vs 37.6%), bleeding events (7.0% vs 3.8%), and secondary primary cancers (2.5% vs 0.4%).
Infusion-related reactions associated with daratumumab were reported in 45.3% of patients. These reactions were mostly grade 1 or 2.
The percentage of patients who discontinued treatment because of at least 1 AE was similar between the daratumumab and control arms (7.4% and 9.3%, respectively).
Long-acting all-injectable HIV therapy successful in phase 2b
DURBAN, SOUTH AFRICA – Long-acting injectable antiretroviral therapy with cabotegravir and rilpivirine in nanosuspension successfully suppressed HIV-infected patients’ plasma viral load to fewer than 50 copies/mL for 48 weeks as maintenance therapy in the LATTE-2 trial, David A. Margolis, MD, reported at the 21st International AIDS Conference.
The intramuscular gluteal injections given every 4 or 8 weeks also proved safe and extremely well tolerated. At week 48, more than 97% of patients on injectable maintenance antiretroviral therapy (ART) reported a high degree of satisfaction with their treatment regimen on a structured questionnaire and expressed a willingness to continue on injectable therapy in the future, according to Dr. Margolis of Viiv Healthcare in Research Triangle Park, N.C.
Cabotegravir is an HIV integrase inhibitor, rilpivirine a nonnucleoside reverse transcriptase inhibitor. Rilpivirine is already approved as Edurant, a once-daily 25-mg tablet for oral therapy. Cabotegravir is under development as a 30-mg once-daily tablet. As oral agents, each has a half-life of roughly 40 hours. The two-drug oral combination showed a high degree of safety and efficacy through 96 weeks of follow-up in the LATTE-1 study, previously reported by Dr. Margolis (Lancet Infect Dis. 2015 Oct;15[10]):1145-55) .
In addition, the two antiretroviral agents are being developed as long-acting injectables with half-lives of 20-90 days. LATTE-2 was a phase IIb, open-label, multicenter study that began with 309 HIV-positive, ART-naive subjects who participated in a 20-week induction phase during which they received 30 mg/day of oral cabotegravir plus abacavir/lamivudine to induce HIV viral suppression. During the last 4 weeks of the induction phase, participants also received oral rilpivirine at 25 mg once daily to ensure they could tolerate the drug.
At the end of the 20-week induction phase, 228 patients with an HIV viral load below 50 copies/mL were randomized 2:2:1 to maintenance therapy with intramuscular injections of long-acting cabotegravir at 200 mg/mL and long-acting rilpivirine at 300 mg/mL in nanosuspension every 4 or 8 weeks or to the oral once-daily versions of the two drugs.
After 48 weeks of maintenance therapy, an HIV RNA load of less than 50 copies/mL was present in 92% of subjects on injections every 8 weeks, 91% with injections every 4 weeks, and 89% of those on oral daily therapy. Moreover, of the eight virologic nonresponders at 48 weeks in the 8-week-injection schedule, six remained in the study and five of them have consistently achieved a viral load below 50 copies/mL in subsequent visits through week 72.
Viral failure defined as an HIV RNA viral load greater than 200 copies/mL on two occasions occurred in 1% of patients on the 8-week interval schedule, 1% of those on oral therapy, and no one on IM injections every 4 weeks. One patient on every-8-week schedule developed treatment-emergent viral resistance.
More than 80% of patients in both IM injection study arms experienced painful injection site reactions after their first treatment session, 82% of which were mild and 17% moderate. Ninety percent of these reactions resolved within 7 days; median duration was 3 days. Two patients withdrew from the study as a result of these reactions. After the first round of injections, the incidence of injection site reactions fell to 25%-30%.
Other adverse events consisted of fever, fatigue, headache, rash, and flu-like symptoms, each with an incidence of 2%-4%.
Based upon the LATTE-2 outcomes, the once-per-month injection regimen has been selected for the forthcoming pivotal phase III randomized clinical trials of long-acting cabotegravir/rilpivirine for ART, Dr. Margolis said.
The pharmaceutical industry is pursuing long-acting injectable ART both for pre-exposure prophylaxis (PrEP) and for treatment of HIV-infected patients. Clinicians and patients alike are eager for this option, especially for PrEP, where adherence to daily oral therapy has been suboptimal in many studies.
But there is a fly in the ointment. One of the most talked about studies presented at AIDS 2016 was Dr. Ian McGowan’s report that low levels of rilpivirine were found in plasma and female genital tract fluids more than 18 months after a single IM 1,200-mg dose of rilpivirine in seven participants in a long-acting PrEP study.
“There is certainly the possibility that extended periods of drug availability at perhaps subtherapeutic concentrations might increase the risk of ART resistance in individuals who seroconvert after exposure to long-acting PrEP,” cautioned Dr. McGowan, professor of medicine at the University of Pittsburgh.
No similar studies have as yet been done with other candidate long-acting injectables, he said.
“It’s clear, I think, that as we move forward with this exciting field of long-acting injectables we really need to better characterize the terminal half-life of these products so that we can better inform management of the pharmacokinetic tail and hopefully avoid the potential for ART resistance,” Dr. McGowan added.
His study was funded by the Bill and Melinda Gates Foundation.

Antibiotics overprescribed during asthma-related hospitalizations
Antibiotics are overprescribed in asthma-related hospitalizations, even though guidelines recommend against prescribing antibiotics during exacerbations of asthma in the absence of concurrent infection, reported Peter K. Lindenauer, MD, MSc, of Baystate Medical Center in Springfield, Mass., and his colleagues.
They examined the hospitalization records of 51,951 individuals admitted to 577 hospitals in the United States between 2013 and 2014 with a principal diagnosis of either asthma or acute respiratory failure combined with asthma as a secondary diagnosis. Each patient type and the timing of antibiotic therapy was noted.
A total of 30,226 of the 51,951 patients (58.2%) were prescribed antibiotics at some point during their hospitalization, while 21,248 (40.9%) were prescribed antibiotics on the first day of hospitalization, without “documentation of an indication for antibiotic therapy.”
Macrolides were most commonly prescribed, given to 9,633 (18.5%) of patients, followed by quinolones (8,632, 16.1%), third-generation cephalosporins (4,420, 8.5%), and tetracyclines (1,858, 3.6%). After adjustment for risk variables, chronic obstructive asthma hospitalizations were found to be those most highly associated with receiving antibiotics (odds ratio 1.6, 95% confidence interval 1.5-1.7).
“Possible explanations for this high rate of potentially inappropriate treatment include the challenge of differentiating bacterial from nonbacterial infections, distinguishing asthma from chronic obstructive pulmonary disease in the acute care setting, and gaps in knowledge about the benefits of antibiotic therapy,” the authors posited, adding that these findings “suggest a significant opportunity to improve patient safety, reduce the spread of resistance, and lower spending through greater adherence to guideline recommendations.”
The National Heart, Lung, and Blood Institute and Veterans Affairs Health Services Research and Development funded the study. Dr. Lindenauer and his coauthors did not report any relevant financial disclosures.
