SAN DIEGO – A novel myeloablative regimen along with familial haploidentical stem cell transplantation was well tolerated and cured 90% of 19 young patients with high-risk sickle cell disease who underwent the procedure, according to Mitchell S. Cairo, MD.

The approach involved parental donors who were partial matches (as opposed to human leukocyte antigen [HLA]–matched sibling donors), CD34 enrichment, and mononuclear cell add-back (2 x 10⁵ CD3/kg). The treatment resulted in a low cumulative incidence of acute and chronic graft-versus-host disease (6.2% and 6.7%, respectively) and stable to improved pulmonary and cardiac function. Patients also experienced significantly improved neurocognition and health-related quality of life at 2-year follow-up, Dr. Cairo of New York Medical College, Valhalla, reported at the annual meeting of the American Society of Hematology.

In a video interview, Dr. Cairo described the study, the potential benefits of familial haploidentical transplantation, and future directions.

“We have a 1-year 90% survival rate, and ... with a median follow-up now of 3 years with this approach, no patient has signs or symptoms of sickle cell disease,” he said. While the standard of care is “still to use an HLA-matched sibling donor that doesn’t have sickle cell disease,” this novel approach could benefit the five of six patients who don’t have such a donor.

The risks appear similar with the two approaches, but “more numbers will be needed to confirm this preliminary finding,” he said.

A second Food and Drug Administration–supported study with patients aged up to age 35 years (vs. 21 years in the current study) and with lower doses of the conditioning regimen to potentially reduce the risk of late adverse effects is underway, he said.

This study was supported by an FDA grant. Dr. Cairo reported receiving research funding from Janssen.

SAN DIEGO – Sickle cell research is booming after decades of stagnation, and talk of a cure is real, according to sickle cell disease expert Ifeyinwa (Ify) Osunkwo, MD.

“There is an opportunity to cure your disease no matter what age you are,” Dr. Osunkwo, medical director of the sickle cell program at Levine Cancer Institute at Atrium Health in Charlotte, N.C., said in a video interview at the annual meeting of the American Society of Hematology. “Sickle cell disease is now a disease of all ages and the treatments have to be treatments for everybody of all ages, not just for children.”

Dr. Osunkwo was the moderator of a press conference highlighting top research in sickle cell disease at ASH 2018. She pointed to findings from first-in-human trials of gene therapy using a lentiviral vector targeting BCL11A to reverse the sickle cell phenotype, as well as a study examining familial haploidentical stem cell transplantation with CD34 enrichment and mononuclear add-back in high-risk patients.

These two studies show parallel progress in curative therapies and are complementary, Dr. Osunkwo said. Improvements in transplants, and specifically in how patients are prepared and managed for them, will have a benefit in gene therapy.

But there are many other sickle cell disease studies being presented at ASH this year, she noted.

“There’s a recognition that sickle cell has been an understudied, underresourced, underexposed population,” she said. “And the suffering and the magnitude of medical problems is huge and it finally has bubbled up to the surface.”

Dr. Osunkwo reported being on advisory committees for Novartis and Pfizer and on the speaker’s bureau for Novartis. She has received honoraria from Terumo BCT and funding from the Health Resources and Services Administration and the Patient-Centered Outcomes Research Institute.

Over one-third of adolescents presenting with heavy menstrual bleeding were diagnosed with a bleeding disorder after screening, according to results of a retrospective study.

The high incidence of bleeding disorders detected argues for routine screening of adolescents with heavy menstrual bleeding (HMB), Brooke O’Brien, MD, of the University of Queensland, Brisbane, Australia, and her colleagues wrote in the Journal of Pediatric & Adolescent Gynecology.

“These findings support comprehensive and systematic hemostatic evaluation in adolescents with HMB,” Dr. O’Brien and her colleagues wrote. “A higher level of awareness of bleeding disorders as a cause for HMB in adolescence, especially [von Willebrand disease] and platelet function disorders, is needed and close multidisciplinary collaboration between the pediatric and adolescent gynecologist and hematologist in a specialized tertiary center should be established in the management of these patients.”

In their study, Dr. O’Brien and her colleagues retrospectively evaluated 124 adolescents with HMB at a pediatric and adolescent gynecology tertiary care center between July 2007 and July 2017. Of these, 77 patients (62.1%) underwent screening for blood disorders.

The researchers found 27 adolescents overall were diagnosed with a blood disorder, which consisted of 35.0% of patients screened and 21.7% of all patients studied. Specifically, 14 of 27 patients (51.6%) screened were diagnosed with von Willebrand disease, 9 of 27 patients (33.3%) screened were found to have inherited platelet function disorders, 3 of 27 patients (11.1%) had inherited or acquired thrombocytopenia, and 1 of 27 patients (3.7%) had factor IX deficiency. The researchers also screened for iron deficiency and/or anemia and found 53 of 107 patients (49.5%) who were screened received a diagnosis, and 19 of 27 patients (70.3%) who were diagnosed with a bleeding disorder also had iron deficiency and/or anemia.

“In adolescents who are already known to have a bleeding disorder, consultation with a pediatric gynecologist and/or hematologist prior to menarche may be helpful to outline abnormal patterns of menstrual bleeding and to discuss options of treatment in the event of heavy menstrual bleeding,” Dr. O’Brien and her colleagues wrote.

Potential limitations in the study include the refractory nature of referrals at a tertiary care center potentially overestimating the prevalence of HMB in this population as well as the study’s retrospective design when investigating and measuring heavy menstrual bleeding, but researchers noted patients were reviewed and classified by a specialist pediatric hematologist.

The authors reported no relevant conflicts of interest.

SAN DIEGO – Patients aged younger than 60 years with favorable-prognosis diffuse large B-cell lymphoma who were randomly assigned to therapy with four cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) had progression-free, event-free, and overall survival rates comparable with those of patients assigned to six cycles, investigators in the FLYER trial reported.

The four-cycle regimen was associated with a marked reduction in adverse events, with an overall drop in nonhematologic malignancies of approximately one-third compared with the six-cycle regimen.

For younger patients with favorable-prognosis DLBCL – defined as an age-adjusted International Prognostic Index score of 0 and low tumor burden (less than 7.5 cm) – four cycles of R-CHOP can be a new standard of care.

In this video interview at the annual meeting of the American Society of Hematology, Viola Poeschel, MD, of Saarland University in Homburg, Germany, describes the patient population who may benefit from shorter duration therapy.

SAN DIEGO – An adult with sickle cell disease has had significant remissions in symptoms and a near elimination of transfusion requirements after receiving an infusion of autologous stem cells genetically modified to simultaneously induce the fetal form of hemoglobin and decrease sickle hemoglobin.

In a first-in-human, proof-of-concept study, transduction of hematopoietic stem cells with a lentiviral vector targeted against the gamma globin repressor BCL11A in erythroid cells led to rapid induction of fetal hemoglobin and a reversal of the sickle cell disease (SCD) phenotype in the early phase of stem cell reconstitution, reported Erica B. Esrick, MD, from the Dana-Farber/Boston Children’s Cancer and Blood Disorders Center in Boston.

“The potential advantage of this approach over the gene-addition strategy of gene therapy is that we can harness the physiologic switch machinery that exists in the cell to simultaneously increase fetal hemoglobin and decrease sickle hemoglobin,” she said at a briefing prior to her presentation at the annual meeting of the American Society of Hematology.

Several research groups are developing autologous gene therapy for beta-hemoglobinopathies, including the use of CRISPR-Cas9 technology to mimic a rare, naturally occurring mutation that causes the fetal type of hemoglobin to persist into adulthood in some patients with SCD and beta-thalassemia.

Dr. Esrick and her colleagues are trying a different approach: Using gene therapy to knock down BCL11A expression to induce gamma globin expression.

For the treatment, autologous hematopoietic stem cells are collected from patients following mobilization with plerixafor. The cells are then transduced with a lentiviral vector consisting of a novel short hairpin RNA embedded in an endogenous micro-RNA. The investigators refer to the construct as a shmiR (“schmeer”). The construct is designed to be erythroid specific, with BCL11A knocked down only in the red cell lineage, to avoid potential off-target effects of the therapy.

Following stem cell collection and transduction, patients undergo conditioning with busulfan prior to infusion of the modified stem cells.

In three patients treated thus far, the process has been shown to be highly efficient, with approximately 96% of treated cells transduced.

In the patient mentioned before, neutrophil engraftment was confirmed on day 22 after transfusion of the modified cells. He experienced adverse events that were consistent with myeloablative conditioning, but no adverse events associated with the modified cells.

During 6 months of follow-up the patient did not experience SCD-related pain, respiratory events, or neurologic events, and did not have anemia, with a total hemoglobin of 11 g/dL at 6 months. He has not required any transfusions since engraftment.

Patients in the trial will be followed for 2 years, and then will be enrolled in a 15-year follow-up study designed to evaluate the safety and the durability of therapy.

Dr. Esrick reported receiving honoraria from Bluebird Bio, maker of the short hairpin RNA construct used in the trial.

SAN DIEGO – Daily hydroxyurea treatment for sickle cell disease is feasible, safe, and effective for children in sub-Saharan Africa, according to the results of a large open-label, phase 1-2, international trial.

Andrew Bowser/MDedge News

Hydroxyurea was associated with reduced rates of malaria and other infections, resulting in improved survival, according to Léon Tshilolo, MD, PhD, of Centre Hospitalier Monkole in Kinshasa, the Democratic Republic of the Congo.

“Based on that data, we believe that wider access to hydroxyurea for sickle cell anemia has the potential to save millions of lives in Africa,” Dr. Tshilolo said in a press conference at the annual meeting of the American Society of Hematology.

Use of hydroxyurea has been limited in Africa because of cost, access issues, and challenges associated with laboratory monitoring, according to the researchers.

Moreover, most of the data on the efficacy of hydroxyurea come from studies conducted in the United States, Europe, and other high-income settings, said the study’s senior author Russell E. Ware, MD, PhD, of Cincinnati Children’s Hospital Center.

“Now that there’s data in an African setting, I think this will go a long way to advancing [hydroxyurea therapy] and encouraging governments, organizations, and pharmaceutical companies to bring it in,” Dr. Ware said in an interview.

In the study by Dr. Ware, Dr. Tshilolo, and their colleagues, 606 children in four sub-Saharan African countries completed a 2-month pretreatment screening phase designed to capture baseline clinical and laboratory data. The children, who were aged 1-10 years, were started at 15-20 mg/kg of hydroxyurea for 6 months, followed by escalation to the maximum tolerated dose.

With a median of 2.5 years of treatment, treated children experienced less pain and anemia, fewer cases of malaria and other infections, and lower rates of transfusions and death versus rates observed in the pretreatment screening phase of the trial.

The rate of vasoocclusive pain during hydroxyurea treatment was 44.6 events per 100 patient-years, compared with 98.3 events per 100 patient-years in the pretreatment period (incidence rate ratio, 0.45; 95% confidence interval, 0.37-0.56), according to data simultaneously published in the New England Journal of Medicine.

Malaria infection rates were 22.9 events per 100 patient-years in the hydroxyurea treatment period versus 46.9 events in the pretreatment period (IRR, 0.49; 95% CI, 0.37-0.66). Rates of nonmalaria infections were 90.0 events per 100 patient-years in the hydroxyurea treatment period versus 142.5 events per 100 patient-years in the pretreatment period (IRR, 0.62; 95% CI, 0.53-0.72).

Dr. Tshilolo said investigators were “encouraged” by the reduced infection rates, particularly in light of previous concerns that hydroxyurea could suppress the immune system and put children at risk for malaria.

Death rates were 1.1 per 100 patient-years in the hydroxyurea group and 3.6 per 100 patient-years in the pretreatment period (IR, 0.30; 95% CI, 0.10-0.88). Dose-limiting toxic events occurred in 5.1% of the children, which was below the protocol-specified threshold for safety, Dr. Tshilolo added.

Dr. Tshilolo reported grants from the National Institutes of Health/National Heart, Lung, and Blood Institute and Cincinnati Children’s Research Foundation, along with nonfinancial support from Bristol-Myers Squibb. Dr. Ware reported grants from the NIH/NHLBI and Bristol-Myers Squibb.

Hydroxyurea was associated with reduced rates of malaria and other infections, resulting in improved survival, according to Léon Tshilolo, MD, PhD, of Centre Hospitalier Monkole in Kinshasa, the Democratic Republic of the Congo.

“Based on that data, we believe that wider access to hydroxyurea for sickle cell anemia has the potential to save millions of lives in Africa,” Dr. Tshilolo said in a press conference at the annual meeting of the American Society of Hematology.

Use of hydroxyurea has been limited in Africa because of cost, access issues, and challenges associated with laboratory monitoring, according to the researchers.

Moreover, most of the data on the efficacy of hydroxyurea come from studies conducted in the United States, Europe, and other high-income settings, said the study’s senior author Russell E. Ware, MD, PhD, of Cincinnati Children’s Hospital Center.

“Now that there’s data in an African setting, I think this will go a long way to advancing [hydroxyurea therapy] and encouraging governments, organizations, and pharmaceutical companies to bring it in,” Dr. Ware said in an interview.

In the study by Dr. Ware, Dr. Tshilolo, and their colleagues, 606 children in four sub-Saharan African countries completed a 2-month pretreatment screening phase designed to capture baseline clinical and laboratory data. The children, who were aged 1-10 years, were started at 15-20 mg/kg of hydroxyurea for 6 months, followed by escalation to the maximum tolerated dose.

With a median of 2.5 years of treatment, treated children experienced less pain and anemia, fewer cases of malaria and other infections, and lower rates of transfusions and death versus rates observed in the pretreatment screening phase of the trial.

The rate of vasoocclusive pain during hydroxyurea treatment was 44.6 events per 100 patient-years, compared with 98.3 events per 100 patient-years in the pretreatment period (incidence rate ratio, 0.45; 95% confidence interval, 0.37-0.56), according to data simultaneously published in the New England Journal of Medicine.

Malaria infection rates were 22.9 events per 100 patient-years in the hydroxyurea treatment period versus 46.9 events in the pretreatment period (IRR, 0.49; 95% CI, 0.37-0.66). Rates of nonmalaria infections were 90.0 events per 100 patient-years in the hydroxyurea treatment period versus 142.5 events per 100 patient-years in the pretreatment period (IRR, 0.62; 95% CI, 0.53-0.72).

Dr. Tshilolo said investigators were “encouraged” by the reduced infection rates, particularly in light of previous concerns that hydroxyurea could suppress the immune system and put children at risk for malaria.

Death rates were 1.1 per 100 patient-years in the hydroxyurea group and 3.6 per 100 patient-years in the pretreatment period (IR, 0.30; 95% CI, 0.10-0.88). Dose-limiting toxic events occurred in 5.1% of the children, which was below the protocol-specified threshold for safety, Dr. Tshilolo added.

Dr. Tshilolo reported grants from the National Institutes of Health/National Heart, Lung, and Blood Institute and Cincinnati Children’s Research Foundation, along with nonfinancial support from Bristol-Myers Squibb. Dr. Ware reported grants from the NIH/NHLBI and Bristol-Myers Squibb.

SAN DIEGO – Researchers were able to “flip the switch” from the adult to fetal form of hemoglobin using autologous stem cells genetically modified to simultaneously induce the fetal form of hemoglobin and decrease sickle hemoglobin.

The advance was announced by investigators at the Dana-Farber Cancer Institute and Boston Children’s Hospital at the annual meeting of the American Society of Hematology. At 6 months of follow-up, one adult patient in the proof-of-concept study has experienced a reversal of the sickle cell phenotype, with no pain episodes or respiratory or neurologic events.

The fetal form of hemoglobin is known to be protective against the signs and symptoms of sickle cell disease, but apart from a few rare exceptions, people with the disorder begin to experience debilitating symptoms as levels of the fetal form begin to decline in early childhood and levels of the adult form of hemoglobin steadily rise.

In this video interview, Erica B. Esrick, MD, from the Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, describes the novel approach of using RNA interference to knock down a repressor that suppresses expression of gamma globin in sickle cell disease.

CHICAGO – Apremilast was effective and well tolerated for up to 28 weeks for the treatment of oral ulcers in patients with active Behçet’s disease, based on findings from the randomized, placebo-controlled, phase 3 RELIEF trial.

At baseline, mean oral ulcer counts were 4.2 in 104 patients randomized to receive the oral phosphodiesterase-4 inhibitor and 3.9 in 103 patients in the placebo group. Mean visual analog scale (VAS) pain scores were 61.2 and 60.8 in the two groups, respectively.

The primary study endpoint of area under the curve for total number of oral ulcers over a 12-week period (AUC_Wk0-12) – a measure that reflects the number of oral ulcers that occur over time and also accounts for the recurring-remitting course of oral ulcers – was achieved. AUC_Wk0-12 was significantly lower in the apremilast group than in the placebo group (129.54 vs. 222.14, respectively; P less than .0001), Gulen Hatemi, MD, reported at the annual meeting of the American College of Rheumatology.

From baseline to week 12, apremilast treatment also resulted in a significantly lower number of oral ulcers (mean of 1.1 vs. 2.0 for placebo at 12 weeks) and significantly reduced pain from oral ulcers at every visit from week 1 through week 12 of the study, compared with placebo (mean VAS score change from baseline, –40.7 vs. –15.9), said Dr. Hatemi, a professor of medicine at Istanbul University.

“The [12-week] complete response rate ... was 53% in the apremilast group and 22.3% in the placebo group. The [12-week] partial response rate ...was 76% in the apremilast group and 48% in the placebo group,” she said, adding that the efficacy of apremilast was sustained with continued treatment through 28 weeks.

Study participants were adults (mean age, 40 years) with active Behçet’s disease and three or more oral ulcers at randomization or two or more at screening and at randomization. All had been previously treated with at least one nonbiologic medication for oral ulcers and were allowed to have received previous biologic therapies for other disease manifestations. Those with active major organ involvement were excluded.

Treatment included a 30-mg dose of apremilast twice daily for 12 weeks or placebo. After 12 weeks, all patients received apremilast through at least 28 weeks of the 64-week study.

At the 28-week analysis, patients who were initially randomized to placebo and who switched to apremilast after week 12 had benefits comparable with those seen in those randomized to apremilast at the start of the study. A complete response was seen in 59% and 62% of patients in the groups, respectively, and a partial response was seen in 90% and 85%, respectively. Additionally, the mean change in the VAS score for oral ulcer pain in the groups at that time was –40.6 and –41.9, Dr. Hatemi said.

Apremilast was well tolerated in this study; the incidence of adverse events was comparable in the treatment and placebo groups during the 12-week placebo-controlled phase of the study – 78.8% and 71.8%, respectively. The most common events were diarrhea, nausea, headache, and upper respiratory tract infection, she said.

“These were generally mild to moderate, and only two patients had to discontinue the study due to gastrointestinal adverse events,” she said, noting that no new safety signals were observed.

Behçet’s disease is a chronic, relapsing, multisystem inflammatory disorder characterized by recurrent oral ulcers that can be disabling and have a substantial effect on quality of life. These findings, which include efficacy data up to 28 weeks and safety data for at least 100 patients exposed to apremilast for at least 1 year, demonstrate the efficacy of apremilast for the treatment oral ulcers in patients with Behçet’s disease, she said, noting that “the safety findings were consistent with the known safety profile of apremilast.”

The RELIEF study was supported by Celgene. Dr. Hatemi reported receiving grant/research support from Celgene and serving as a speaker for AbbVie, Mustafa Nevzet Pharmaceuticals, and UCB.

NEW ORLEANS – Depression severity is correlated with seizure frequency and quality of life in adults with epilepsy, according to an analysis presented at the annual meeting of the American Epilepsy Society.

The conclusion comes from a study of 120 people with epilepsy, 62 of whom had at least moderate depression based on the Patient Health Questionnaire-9 (PHQ-9). The Rapid Estimate of Adult Literacy in Medicine (REALM-R), Quality of Life in Epilepsy (QOLIE-10) and Charlson Comorbidity Index were used to assess patients’ health literacy, quality of life, and medical comorbidity, respectively

Among demographic characteristics, only inability to work was significantly associated with depression severity. Higher 30-day seizure frequency, panic disorder, and obsessive-compulsive disorder were correlated with more severe depression severity. Medical comorbidity was not associated with increased risk of depression.

Identifying and treating psychiatric comorbidities should be part of the management of patients with epilepsy, said Martha X. Sajatovic, MD, director of the Neurological and Behavioral Outcomes Center at Case Western Reserve University in Cleveland, who presented the data. “Following up to ensure they receive treatment is vital, because it can truly change patient outcomes and help them achieve their best quality of life.”

The study findings are consistent with those of previous research indicating that people with symptoms of depression are more likely to have more frequent seizures and decreased quality of life, said Dr. Sajatovic.

“Health care providers should screen their epilepsy patients for depression, but they shouldn’t stop there,” she advised. “A person may have depressive symptoms that don’t reach the level of depression but should be assessed for other types of mental health issues that could easily be overlooked.”

Patients with epilepsy should respond to the PHQ-9 annually, or more frequently, if warranted, she added.

“It’s important that people with epilepsy who have depression or other mental health issues get treatment such as cognitive behavioral therapy and medication,” said Dr. Sajatovic. “Even being in a self-management program helps, because the better they are at self management, the less likely they are to suffer negative health effects.”

This study was supported by a grant from the Centers for Disease Control and Prevention SIP 14-007 1U48DP005030.

NEW ORLEANS – Patients taking enzyme-inducing antiepileptic drugs (AEDs) may require a clinically meaningful increase in their vitamin D doses to achieve the same 25-hydroxyvitamin D (25[OH]D) plasma levels as patients taking nonenzyme-inducing AEDs, based on a retrospective chart review presented at the annual meeting of the American Epilepsy Society.

While patients receiving either type of AED had similar average 25(OH)D levels in the study (32.0 ng/mL in the enzyme-inducing AED group and 33.2 ng/mL in the noninducing AED group), those in the enzyme-inducing group required 1,587 U/day to meet the goal – a 409-unit increase in dose, compared with the 1,108 U/day dose taken by patients in the nonenzyme-inducing group.

“Patients taking enzyme-inducing AEDs may benefit from more intensive monitoring of their vitamin D supplementation, and clinicians should anticipate this likely pharmacokinetic interaction,” said Barry E. Gidal, PharmD, professor of pharmacy and neurology at the University of Wisconsin–Madison, and his colleagues.

Researchers have suggested that enzyme-inducing AEDs may affect CYP450 isoenzymes, increase vitamin D metabolism, and reduce 25(OH)D plasma levels. “It follows … that a potential pharmacokinetic interaction could exist between enzyme-inducing AEDs and oral formulations of vitamin D used for supplementation,” the investigators said.

To test the hypothesis, Dr. Gidal and his colleagues reviewed the charts of patients with epilepsy who were on any AED regimen and were prescribed vitamin D at William S. Middleton Memorial Veterans Hospital in Madison, Wisconsin, between January 2013 and September 2017.

The researchers grouped patients by those using enzyme-inducing AEDs and those taking noninducing AEDs. Patients who were taking AEDs in both categories were placed in the enzyme-inducing AED group. Patients with malabsorptive conditions and patients using calcitriol were excluded from the analysis.

Data included AEDs used, prescription and over-the-counter vitamin D use, 25(OH)D plasma concentration, renal function, age, gender, and ethnicity. Patients’ 25(OH)D levels were measured using a chemiluminescence immunoassay, and a minimum 25(OH)D plasma level of 30 ng/mL was the therapeutic goal.

The multivariant analysis was adjusted for potentially confounding variables including 25(OH)D concentration, over-the-counter vitamin D use, chronic kidney disease, age, gender, and ethnicity.

The analysis included 1,113 observations from 315 patients, and 263 of the observations (23.6%) were in the enzyme-inducing AED group. The enzyme-inducing group and noninducing groups were mostly male (90.5% and 91.8%, respectively) and similar in average age (65.9 and 61.4 years, respectively). Variables were evenly distributed between the groups, with the exceptions of chronic kidney disease, which was less common in the enzyme-inducing group (6.1% vs. 13.8%), and ethnicity (78.7% Caucasian in the enzyme-inducing group vs. 87.7% Caucasian in the noninducing group). The most common enzyme-inducing AED was phenytoin (50.6%), followed by carbamazepine (31.9%), phenobarbital (14.1%), oxcarbazepine (6.8%), primidone (1.9%), and eslicarbazepine (0.8%).

NEW ORLEANS – Patients taking enzyme-inducing antiepileptic drugs (AEDs) may require a clinically meaningful increase in their vitamin D doses to achieve the same 25-hydroxyvitamin D (25[OH]D) plasma levels as patients taking nonenzyme-inducing AEDs, based on a retrospective chart review presented at the annual meeting of the American Epilepsy Society.

While patients receiving either type of AED had similar average 25(OH)D levels in the study (32.0 ng/mL in the enzyme-inducing AED group and 33.2 ng/mL in the noninducing AED group), those in the enzyme-inducing group required 1,587 U/day to meet the goal – a 409-unit increase in dose, compared with the 1,108 U/day dose taken by patients in the nonenzyme-inducing group.

“Patients taking enzyme-inducing AEDs may benefit from more intensive monitoring of their vitamin D supplementation, and clinicians should anticipate this likely pharmacokinetic interaction,” said Barry E. Gidal, PharmD, professor of pharmacy and neurology at the University of Wisconsin–Madison, and his colleagues.

Researchers have suggested that enzyme-inducing AEDs may affect CYP450 isoenzymes, increase vitamin D metabolism, and reduce 25(OH)D plasma levels. “It follows … that a potential pharmacokinetic interaction could exist between enzyme-inducing AEDs and oral formulations of vitamin D used for supplementation,” the investigators said.

To test the hypothesis, Dr. Gidal and his colleagues reviewed the charts of patients with epilepsy who were on any AED regimen and were prescribed vitamin D at William S. Middleton Memorial Veterans Hospital in Madison, Wisconsin, between January 2013 and September 2017.

The researchers grouped patients by those using enzyme-inducing AEDs and those taking noninducing AEDs. Patients who were taking AEDs in both categories were placed in the enzyme-inducing AED group. Patients with malabsorptive conditions and patients using calcitriol were excluded from the analysis.

Data included AEDs used, prescription and over-the-counter vitamin D use, 25(OH)D plasma concentration, renal function, age, gender, and ethnicity. Patients’ 25(OH)D levels were measured using a chemiluminescence immunoassay, and a minimum 25(OH)D plasma level of 30 ng/mL was the therapeutic goal.

The multivariant analysis was adjusted for potentially confounding variables including 25(OH)D concentration, over-the-counter vitamin D use, chronic kidney disease, age, gender, and ethnicity.

The analysis included 1,113 observations from 315 patients, and 263 of the observations (23.6%) were in the enzyme-inducing AED group. The enzyme-inducing group and noninducing groups were mostly male (90.5% and 91.8%, respectively) and similar in average age (65.9 and 61.4 years, respectively). Variables were evenly distributed between the groups, with the exceptions of chronic kidney disease, which was less common in the enzyme-inducing group (6.1% vs. 13.8%), and ethnicity (78.7% Caucasian in the enzyme-inducing group vs. 87.7% Caucasian in the noninducing group). The most common enzyme-inducing AED was phenytoin (50.6%), followed by carbamazepine (31.9%), phenobarbital (14.1%), oxcarbazepine (6.8%), primidone (1.9%), and eslicarbazepine (0.8%).
