Systemic Osteoporosis and Osteopenia Among Periprosthetic Fractures After Total Hip Arthroplasty.

BACKGROUND: Most periprosthetic fractures following total hip arthroplasty (THA) are fragility fractures that qualify patients for osteoporosis diagnoses. However, it remains unknown how many patients were diagnosed who had osteoporosis before injury or received the proper evaluation, diagnosis, and treatment after injury. METHODS: We identified 171 Vancouver B2 (109) and B3 (62) periprosthetic femur fractures treated with a modular fluted tapered stem from 2000 to 2018 at one institution. The mean patient age was 75 years (range, 35 to 94), 50% were women, and the mean BMI was 29 (range, 17 to 60). We identified patients who had osteoporosis or osteopenia diagnoses, a fracture risk assessment tool (FRAX), bone mineral density (BMD) testing, an endocrinology consult, and osteoporosis medications. Age-appropriate BMD testing was defined as no later than one year after the recommended ages of 65 (women) or 70 years (men). The mean follow-up was 11 years (range, 4 to 21). RESULTS: Falls from standing height caused 94% of fractures and thus, by definition, qualified as osteoporosis-defining events. The prevalence of osteoporosis diagnosis increased from 20% before periprosthetic fracture to 39% after (P < 0.001). The prevalence of osteopenia diagnosis increased from 13% before the fracture to 24% after (P < 0.001). The prevalence of either diagnosis increased from 24% before fracture to 44% after (P < 0.001). No patients had documented FRAX scores before fracture, and only 2% had scores after. The prevalence of BMD testing was 21% before fracture and 22% after (P = 0.88). By the end of the final follow-up, only 16% had received age-appropriate BMD testing. The proportion of patients who had endocrinology consults increased from 6% before the fracture to 25% after (P < 0.001). The proportion on bisphosphonate therapy was 19% before fracture and 25% after (P = 0.08). CONCLUSIONS: Although most periprosthetic fractures following THA are fragility fractures that qualify patients for osteoporosis diagnoses, there remain major gaps in diagnosis, screening, endocrinology follow-up, and treatment. Like non-arthroplasty fragility fractures, a systematic approach is needed after periprosthetic fractures.

Relationships between adrenal insufficiency and cardiovascular outcomes in patients with atrial fibrillation, atrial flutter and paroxysmal supraventricular tachycardia.

BACKGROUND: Patients with Adrenal Insufficiency (AI) face elevated cardiovascular risks, but little remains known about arrhythmia outcomes in this context. METHOD: Analyzing the 2016-2019 Nationwide Inpatient Sample, we identified cases of Atrial Fibrillation, Atrial Flutter, and paroxysmal supraventricular tachycardia (PSVT) with a secondary diagnosis of AI. Mortality was the primary outcome while vasopressors and/or mechanical ventilation use, length of stay (LOS), and total hospitalization charges (THC) constituted secondary outcomes. Multivariate linear and logistic regression models were used to adjust for confounders. RESULTS: Among patients with Atrial Fibrillation, Atrial Flutter, and PSVT (N=1,556,769), 0.2% had AI. AI was associated with higher mortality (adjusted OR [aOR] 2.29, p=0.001), vasopressor and/or mechanical ventilation use (aOR 2.54, p<0.001), THC ($62,347 vs. $41,627, p<0.001) and longer LOS (4.4 vs. 3.2 days, p<0.001) compared to no AI. CONCLUSION: AI was associated with higher adverse outcomes in cases of Atrial Fibrillation, Atrial Flutter, and PSVT.

Improving Handoffs After Osteoporotic Fractures.

Osteoporotic fractures among long-term care residents have substantial economic and human costs. After a fracture, many older adults do not receive an osteoporosis diagnosis or evidence-based treatment, which leads to increased risk of recurrent fractures. Optimal processes are well defined for transitioning medical care after a hip or vertebral fracture for osteoporosis evaluation, but the handoff process from the specialist back to a primary care practitioner (PCP) or to a rehabilitative setting is not well defined. Our interdisciplinary quality improvement team developed and evaluated a program for transitioning care from a hospital-based fracture liaison clinic (FLC) to PCPs caring for older adults across the care continuum. To understand the current process of postfracture care transitions, we analyzed the postfracture patient experience. We surveyed PCPs to assess barriers to osteoporosis treatment, and retrospectively conducted a baseline analysis of 87 patients who had sustained an osteoporotic fracture in 2020. This preliminary work showed several opportunities for practice improvement and helped us develop a practical multicomponent intervention aimed at improving care transitions from the FLC to PCPs. The intervention (June-September 2021) comprised a standardized documentation template in the electronic health record (EHR) for FLC clinicians, a structured handoff process, and an engagement tool for patients outlining the roles and responsibilities of each care team member. We compared care transition measures before and after intervention. EHR documentation of an osteoporosis diagnosis increased from 56% (49 of 87 patients) before intervention to 92% (48 of 52) after intervention (P < .001). Additionally, increases were observed in documentation of treatment recommendations, associated risk factors, and PCP discussions with patients regarding osteoporosis and related treatment. This practical, commonsense intervention established clear roles for each care team member. The intervention addressed systemwide barriers in facilitating a safe transition from a subspecialty care team to PCPs providing care to older adults with osteoporosis.

Clozapine and neutrophil response in patients of African descent: A six-month, multinational, prospective, open-label clinical trial.

INTRODUCTION: Clozapine is the most effective antipsychotic for treatment-resistant schizophrenia, but it is markedly underutilized, particularly in the US Black population, partly because of concern over clozapine-associated low absolute neutrophil count (ANC). People of African descent have a lower normative ANC range than the White population, which is associated with a specific "ACKR1-null" ("Duffy null") CC genotype (SNP rs2814778) on the ACKR1 gene, termed benign ethnic neutropenia (BEN). The range of ANC variability and safety of clozapine have not been established in people with BEN or examined prospectively in people of African descent. METHODS: We completed a multisite, 6-month, prospective, open-label clinical trial of clozapine treatment in people of African descent with schizophrenia spectrum disorders for whom clozapine was clinically indicated, with or without the ACKR1-null genotype. We examined clozapine safety and weekly ANC during clozapine treatment and evaluated ANC variability by ACKR1-null genotype, sex, study site, and clozapine dosing using repeated measures analysis of covariance. Genotype was assayed using TaqMan® technology. RESULTS: We enrolled 274 participants, of whom 227 (82.8 %) completed 6 months of clozapine treatment. There was one case of severe neutropenia (<500 cells/mm3) (0.36 %) over 1467.6 person-months of clozapine exposure. This participant recovered without sequelae after discontinuation of clozapine. Of the 249 participants with known genotypes, 199 (79.9 %) had the ACKR1-null genotype. Neutropenia (<1500 cells/mm3) occurred significantly more often in the ACKR1-null group (33 % [65/199]) than in those with the T allele (6 % (3/50); p < 0.001). Fourteen (5 %) patients discontinued due to adverse events. Rates of infection and fever were low and sialorrhea was the commonest side effect (N = 187, 68 %). CONCLUSION: To our knowledge, this is the largest prospective clozapine trial in people of African descent. Severe neutropenia was rare, despite the high prevalence (80 %) of the ACKR1-null genotype. Our findings suggest that clozapine can be used safely in Black patients including those with BEN.

Managing Bone Health in Breast Cancer.

OBJECTIVE: Osteoporosis is a common condition that can be caused or exacerbated by estrogen deficiency. METHODS: This narrative review will discuss optimizing bone health in the setting of adjuvant endocrine treatments for hormone receptor-positive breast cancer and the current use of antiresorptive agents as adjuvant therapy and as bone modifying agents. RESULTS: Adjuvant endocrine treatments for hormone receptor-positive breast cancer (tamoxifen and aromatase inhibitors) affect bone health. The exact effect depends on the agent used and the menopausal state of the woman. Antiresorptive medications for osteoporosis, bisphosphonates and denosumab, lower the risk of bone loss from aromatase inhibitors. Use of bisphosphonates as adjuvant treatment in breast cancer, regardless of hormone receptor status, is increasing because of benefits seen to cancer relapse and survival. CONCLUSION: Optimizing bone health in women with breast cancer during and after cancer treatment is informed by an understanding of breast cancer treatment and its skeletal effect.

Persistence and Recurrence of Hypercalcemia After Parathyroidectomy Over 5 Decades (1965-2010) in a Community-based Cohort.

BACKGROUND: There is limited long-term follow-up of patients undergoing parathyroidectomy. Recurrence is described as 4% to 10%. This study evaluated persistence and recurrence of hypercalcemia in primary hyperparathyroidism after parathyroidectomy. METHODS: Single-institution retrospective (1965-2010) population-based cohort from Olmsted County (MN) of patients undergoing surgery for primary hyperparathyroidism. Patients' demographic data, preoperative and postoperative laboratory values, clinical characteristics, surgical treatment, and follow-up were noted. RESULTS: A total of 345 patients were identified, 75.7% female, and median age 58.4 years [interquartile range (IQR): 17.6]. In all, 68% of patients were asymptomatic and the most common symptoms were musculoskeletal complaints (28.4%) and nephrolithiasis (25.6%). Preoperative median serum calcium was 11 mg/dL (IQR: 10.8-11.4 mg/dL), and median parathyroid hormone was 90 pg/mL (IQR: 61-169 pg/dL). Bilateral cervical exploration was performed in 38% and single gland resection in 79% of cases. Median postoperative serum calcium was 9.2 mg/dL (IQR: 5.5-11.3). Nine percent of patients presented persistence of hypercalcemia, and recurrence was found in 14% of patients. Highest postoperative median serum calcium was 10 mg/dL (IQR: 6-12.4), and median number of postoperative calcium measurements was 10 (IQR: 0-102). Postoperative hypercalcemia was identified in 37% of patient. Fifty-three percent were attributed to secondary causes, most commonly medications, 22%. Three percent of patients required treatment for postoperative hypercalcemia. Median time to recurrence and death were 12.2 and 16.7 years, respectively. CONCLUSION: Recurrent hypercalcemia after successful parathyroidectomy is higher than previously reported. Most cases are transient and often associated to other factors with only the minority requiring treatment. Long-term follow-up of serum calcium should be considered in patients after successful parathyroidectomy.

Coronary artery calcium and bone mineral density by serial CTA: Does menopausal hormone therapy modify the association?

INTRODUCTION: Both osteoporosis and cardiovascular disease (CVD) increase in women after menopause. Estrogen deficiency is thought to be an underlying mechanism for both these conditions. METHODS: Healthy menopausal women (n = 374, age 42-58 years) underwent cardiac CT scans over four years as participants in the Kronos Early Estrogen Prevention Study (KEEPS), a randomized, controlled trial to Women randomized to either oral conjugated equine estrogens (o-CEE, n = 104), transdermal 17ß-estradiol (t-E2, n = 119) or placebo (n-115). CAC (Agatston units, AU), and BMD (mg/cm3) were measured from thoracic vertebrae at baseline and at the 4 years of the study using validated software. ANOVA and multiple linear regression analyzed the association between incident CAC or progression of CAC and BMD among the treatment groups. RESULTS: At baseline 374 women, 40 participants with CAC >0 had greater decrements in BMD than the 334 participants with CAC = 0 at baseline, The average change in BMD in o-CEE group with CAC was -9.6 ± 13.3 versus -3.1 ± 19.5 in those with zero CAC, p = 0.0018. With t-E2, BMD changed by -11.7 ± 26.2 in those with CAC versus +5.7 ± 26.2 in the zero CAC group, p ≤ 0. 0001. Similarly in the 66 participants that showed progression of CAC >1, had more BMD loss, than those with stable CAC regardless of the treatment. CONCLUSION: Progression of bone loss is reduced among women treated with o-CEE or t-E2. Progression of CAC is associated with greater BMD loss, a relationship that is differentially modified by t-E2 and o-CEE.

25-Hydroxyvitamin D and metabolic-related laboratory values in women with schizophrenia and hyperprolactinemia.

Schizophrenia is a severe mental disorder with various medical comorbidities and early mortality. Hyperprolactinemia is common in women and its impact on sexual function, galactorrhea and amenorrhea is well known. This paper evaluates the risk of 25-hydroxy vitamin D deficiency and other metabolic related laboratory abnormalities in women with schizophrenia having hyperprolactinemia (N = 43). The mean prolactin level in these women was 88.5 ± 56.0 ng/mL. We found that 100% of women were overweight of which 74% (32/43) of the women were obese, 56% (23/41) had abnormal total cholesterol levels and 30% (13/43) had high fasting blood glucose. Vitamin D levels were considered deficient or inadequate in 37% of women. We did not see significant correlations of prolactin with laboratory measures, however all female patients had elevated and high prolactin levels, leading to low variability in a small sample, which may have precluded seeing any direct relationships. Recognizing prolactin related side effects and understanding the role of other health measures seen in women with antipsychotic induced hyperprolactinemia in our female patients are critical steps toward better personalization of their care and recovery.

Anti-aggressive effects of clozapine in involuntarily committed black patients with severe mental illness.

INTRODUCTION: Patients with severe mental illness are falsely characterized as aggressive by the media, perpetuating stigma. While exaggerated, some patients with severe mental illness are more aggressive without treatment. Clozapine may have a unique anti-aggressive effect in patients with schizophrenia-related disorders, independent of antipsychotic or sedative effects. Limited data in forensic and involuntary committed patients is currently available. PURPOSE: This study evaluates clozapine's effects on hostility and aggression in court-ordered Black patients. METHODS: This study analyzes a subgroup of Black patients from a larger prospective 24-week open-label clozapine study. All patients were involuntarily committed and enrolled from two participating state psychiatric hospitals. The primary outcome measured was total use of 'as needed' (PRN) or 'immediate need' (STAT) medications for aggression/hostility. Secondary outcomes included number and duration of seclusion and restraint (S/R) episodes, and changes in Brief Psychiatric Rating Scale (BPRS) hostility factor score. RESULTS: Sixty-nine patients were included in our analysis. Significant reductions were noted in PRN/STAT medication use over time (χ2 = 6.90; p = 0.008) and the BPRS hostility factor score was reduced by 30% over the 24 weeks (F = 4.34, df = 62, p = 0.002). CONCLUSIONS: Treatment with clozapine effectively reduced hostility and aggression within this cohort of involuntarily committed Black patients with mental illness compared to baseline. Specifically, it helped lower the total number of PRN/STAT medication administrations and improved clinician-rated hostility factor scores on the BPRS. Our findings are pertinent as data in forensic settings is lacking and Black patients have been infrequently included in large prospective clinical trials with clozapine.

Survival in primary hyperparathyroidism over five decades (1965-2010) a population-based retrospective study.

CONTEXT: Survival in patients with primary hyperparathyroidism (PHPT) remains uncertain. OBJECTIVE: To update survival in patients with PHPT in a United States community population. DESIGN: Retrospective cohort study. SETTING: Community population in Rochester, Minnesota. PARTICIPANTS: Residents who met criteria for PHPT from 1965 to 2010. INTERVENTIONS: Survival was estimated using the Kaplan Meier product-limit method. The Cox proportional hazards model was used to determine associations, as relative hazards (RR) with 95% confidence intervals (CI), of various risk factors with time to death. MAIN OUTCOME MEASURE: The overall age and gender-adjusted survival compared to white Minnesota residents. RESULTS: We identified 1139 PHPT individuals, 76% female, with a median age of 58 years. Most were observed without parathyroidectomy (69%). The relative risk of death among the entire cohort was 0.996 (95% CI: 0.91-1.09, P = 0.935) which was not different compared to Minnesota residents. Those with maximum serum calcium level ≥ 10.8 mg/dL (0.7 mg/dL above the reference range) had an increase in mortality (RR 1.32, 95% CI: 1.10-1.58, P = 0.002). Survival among all PHPT individuals after parathyroidectomy was no different from expected (RR = 1.06, 95% CI 0.89-1.28; P = 0.508). Mortality was significantly decreased after parathyroidectomy in those with serum calcium levels ≥10.8 mg/dL (HR 0.47, 95% CI: 0.36-0.61, P < 0.001). CONCLUSIONS: Mortality in the entire cohort was not different from expected. PHPT patients with a maximum serum calcium level ≥ 10.8 mg/dL had increased mortality. Survival was improved after parathyroidectomy in those with this degree of hypercalcemia.

Evaluation of Factors Associated With Fracture and Loss of Bone Mineral Density Within 1 Year After Liver Transplantation.

OBJECTIVE: Orthotopic liver transplant recipients are at high risk of fragility fractures both in pre-liver transplant (pre-LT) and in the immediate posttransplant (post-LT) period. The aims of this study were to identify risk factors associated with post-LT fracture and identify factors that contribute to changes in bone mineral density (BMD) in post-LT as they relate to the risk of fracture in the immediate post-LT period. METHODS: We conducted a retrospective cohort study of first-time LT recipients who had BMD testing within 2-year pre-LT and 1-year post-LT. We assessed factors associated with immediate post-LT fracture using logistic regression models and linear regression models. RESULTS: New fractures occurred in 41/286 (14.3%) of LT recipients during the first year following LT. In multivariate analysis, we noted an increased odds of fracture for patients with prior history of fracture (P < .001), patients who were older (P = .03), patients with higher end-stage liver disease score (P = .03), and patients with lower BMD. After adjustment for multiple testing, only a history of prior fracture was statistically significant. CONCLUSION: Our study demonstrated that prior fracture at any site was associated with developing a new fracture in the first year post-LT.

Secondary Fracture Prevention: Consensus Clinical Recommendations from a Multistakeholder Coalition.

Osteoporosis-related fractures are undertreated, due in part to misinformation about recommended approaches to patient care and discrepancies among treatment guidelines. To help bridge this gap and improve patient outcomes, the American Society for Bone and Mineral Research assembled a multistakeholder coalition to develop clinical recommendations for the optimal prevention of secondary fractureamong people aged 65 years and older with a hip or vertebral fracture. The coalition developed 13 recommendations (7 primary and 6 secondary) strongly supported by the empirical literature. The coalition recommends increased communication with patients regarding fracture risk, mortality and morbidity outcomes, and fracture risk reduction. Risk assessment (including fall history) should occur at regular intervals with referral to physical and/or occupational therapy as appropriate. Oral, intravenous, andsubcutaneous pharmacotherapies are efficaciousandcanreduce risk of future fracture.Patientsneededucation,however, about thebenefitsandrisks of both treatment and not receiving treatment. Oral bisphosphonates alendronate and risedronate are first-line options and are generally well tolerated; otherwise, intravenous zoledronic acid and subcutaneous denosumab can be considered. Anabolic agents are expensive butmay be beneficial for selected patients at high risk.Optimal duration of pharmacotherapy is unknown but because the risk for second fractures is highest in the earlypost-fractureperiod,prompt treatment is recommended.Adequate dietary or supplemental vitaminDand calciumintake shouldbe assured. Individuals beingtreatedfor osteoporosis shouldbe reevaluated for fracture risk routinely, includingvia patienteducationabout osteoporosisandfracturesandmonitoringfor adverse treatment effects.Patients shouldbestronglyencouraged to avoid tobacco, consume alcohol inmoderation atmost, and engage in regular exercise and fall prevention strategies. Finally, referral to endocrinologists or other osteoporosis specialists may be warranted for individuals who experience repeated fracture or bone loss and those with complicating comorbidities (eg, hyperparathyroidism, chronic kidney disease).

Non-contrast cardiac CT-based quantitative evaluation of epicardial and intra-thoracic fat in healthy, recently menopausal women: Reproducibility data from the Kronos Early Estrogen Prevention Study.

BACKGROUND: Cardiac fat is emerging as an important parameter for cardiovascular risk stratification. Accurate and reproducible volumetric measurements can facilitate in the serial assessment of cardiac fat by computed tomography (CT). We assessed the intra- and inter-observer variability of cardiac fat volumetric measurements using a semi-automated CT software. METHODS: We used non-contrast coronary calcium CT scans to quantify epicardial and intra-thoracic fat volumes. Two expert readers analyzed baseline and follow up CT scans of 45 subjects by using a semi-automated CT software (QFAT 2.0, Cedars Sinai-Medical Center). Correlation and Bland-Altman analysis was performed for both intra- and inter-observer comparisons for each cardiac fat type. RESULTS: The intra-observer correlation coefficients ranged between 0.86 to 0.99 and 0.87 to 0.99 for epicardial (median fat per reader (cm3) 20.9 to 25.7) and intra-thoracic (median fat per reader (cm3) 27.1 to 31.6) fat volumes respectively, with no significant differences between individual data points (all p > 0.38). The inter-observer correlation coefficient was 0.99 (p < 0.0001 for correlation) for both epicardial and intra-thoracic fat. By Bland-Altman analysis for epicardial fat measurements, mean difference of intra-observer was 0.90 cm3 with 95% confidence intervals (0.22,1.7) and -1.8 cm3 for inter-observer, with 95% CI (-2.9, -0.69). Bland-Altman plots for intra-thoracic fat measurements were similarly impressive for both inter- and intra-observer reads. CONCLUSIONS: Our data showed that measuring epicardial and intra-thoracic fat volumes by CT using a semi-automated software has excellent intra-observer and inter-observer reliability. Cardiac fat volumes can be obtained easily and reproducibly from routine calcium scoring scans and may help in assessing cardiovascular risk.

Effects of Hormone Therapy on Heart Fat and Coronary Artery Calcification Progression: Secondary Analysis From the KEEPS Trial.

Background Heart fats (epicardial and paracardial adipose tissue [PAT]) are greater after menopause. Endogenous estrogen may regulate these fat depots. We evaluated the differential effects of hormone therapy formulations on heart fat accumulations and their associations with coronary artery calcification (CAC) progression in recently menopausal women from KEEPS (Kronos Early Estrogen Prevention Study). Methods and Results KEEPS was a multicenter, randomized, placebo-controlled trial of the effects of 0.45 mg/d oral conjugated equine estrogens and 50 µg/d transdermal 17ß-estradiol, compared with placebo, on 48-month progression of subclinical atherosclerosis among 727 early menopausal women. CAC progression was defined if baseline CAC score was 0 and 48-month CAC score was >0 or if baseline CAC score was >0 and <100 and annualized change in CAC score was ≥10. Of 727 KEEPS participants, 474 (mean age: 52.7 [SD: 2.6]; 78.1% white) had computed tomography-based heart fat and CAC measures at both baseline and 48 months. Compared with women on placebo, women on oral conjugated equine estrogens were less likely to have any increase in epicardial adipose tissue (odds ratio for oral conjugated equine estrogens versus placebo: 0.62 [95% CI, 0.40-0.97]; P=0.03). PAT did not change in any group. Changes in epicardial adipose tissue and PAT did not differ by treatment group. CAC increased in 14% of participants. The assigned treatment modified the association between PAT changes and CAC progression (P=0.02) such that PAT increases were associated with CAC increases only in the transdermal 17ß-estradiol group. Conclusions In recently menopausal women, oral conjugated equine estrogens may slow epicardial adipose tissue accumulation, whereas transdermal 17ß-estradiol may increase progression of CAC associated with PAT accumulation.

Clinical characteristics and depression score response after parathyroidectomy in primary hyperparathyroidism.

OBJECTIVE: Several studies indicate that patients with primary hyperparathyroidism (PHPT) undergoing parathyroid surgery have improvement in mood and neuropsychological functioning. The current analysis aims to examine the relationship between biochemical and clinical variables and the improvement in depression scores and in specific symptoms, after parathyroidectomy. DESIGN: A prospective observational case-control study at a referral centre. PATIENTS: Patients with PHPT undergoing parathyroidectomy (n = 88) or thyroid surgery (n = 85). MEASUREMENTS: The Patient Health Questionnaire-9 (PHQ-9) was utilized to obtain depression scores at enrolment and 12 months after surgery. The changes in PHQ-9 were analysed and correlated with baseline clinical and biochemical parameters. RESULTS: At enrolment, there was no difference between the groups in the number with a depression diagnosis (PHPT 34.1%, thyroid surgery, 35.5%, P = 0.86). However, baseline PHQ-9 scores were significantly higher in PHPT (median 7.5, range 0-27) than thyroid surgery patients (median 3.0, range 0-18, P < 0.0001). Following surgery, all PHQ-9 scores, total and symptom group (cognitive, somatic) improved and were no longer different between PHPT (total PHQ-9 median 2, range 0-16) and thyroid (median 1, range 0-14, P = 0.31) groups. Baseline parathyroid hormone level, but not calcium, had a weak relationship with change in PHQ-9 score after parathyroid surgery (P = 0.003). Baseline PHQ-9 score was correlated with change in PHQ-9 score at 12 months after parathyroid surgery (P < 0.001). CONCLUSIONS: Depression scores improve in both somatic and cognitive domains after parathyroidectomy for PHPT and baseline severity of depression predicts the response.

Adjunct Aripiprazole Reduces Prolactin and Prolactin-Related Adverse Effects in Premenopausal Women With Psychosis: Results From the DAAMSEL Clinical Trial.

PURPOSE/BACKGROUND: Prolactin-related adverse effects contribute to nonadherence and adverse health consequences, particularly in women with severe mental illness. Treating these adverse effects may improve treatment acceptability, adherence, and long-term outcomes. METHODS/PROCEDURES: Premenopausal women with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder were recruited for a randomized, double-blind, placebo-controlled 16-week trial of adjunct aripiprazole (5-15 mg/d). Participants had elevated prolactin (>24 ng/mL) and were experiencing galactorrhea, amenorrhea, oligomenorrhea, or sexual dysfunction on a prolactin-elevating antipsychotic. Participants were evaluated biweekly for prolactin elevation and galactorrhea and completed a menstrual diary review. Psychiatric symptoms and adverse effects were closely monitored. FINDINGS/RESULTS: Forty-six women were randomized (n = 25 aripiprazole, n = 21 placebo). Thirty-seven completed at least 8 weeks of the study (n = 20 [80%] aripiprazole and n = 17 [81%] placebo). Aripiprazole (mean dose, 11.7 ± 2.4 mg/d) was effective for lowering prolactin relative to placebo (P = 0.04). In addition, 45% (9/20) of the aripiprazole group had a normalized prolactin (<24 mg/mL) compared with 12% (2/17) of the placebo group (P = 0.028). Galactorrhea resolved in 77% (10/13) of the aripiprazole-treated participants compared with 33% (4/12) in the placebo group (P = 0.028). Normalization of sexual function (<16 on the Arizona Sexual Experience Scale) occurred in 50% on aripiprazole (7/14) versus 9% (1/11) on placebo (P = 0.030). No differences between groups in symptoms or adverse effects were noted. Overall, women rated a mean score of 4.6 ± 0.6 on a 5-point Likert scale for sexual function improvement, suggesting their particular satisfaction with improvement in this domain. IMPLICATIONS/CONCLUSIONS: Building upon prior studies, this rigorous evaluation confirms the utility of adjunctive aripiprazole as a strategy for improving prolactin and managing prolactin-related adverse effects in premenopausal women with psychosis.

Pharmacokinetics and Safety Assessment of l-Tetrahydropalmatine in Cocaine Users: A Randomized, Double-Blind, Placebo-Controlled Study.

Cocaine use disorder (CUD) remains a significant public health challenge. l-Tetrahydropalmatine (l-THP), a well-tolerated and nonaddictive compound, shows promise for the management of CUD. Its pharmacologic profile includes blockade at dopamine and other monoamine receptors and attenuation of cocaine self-administration, reinstatement, and rewarding properties in rats. This study evaluated the safety of l-THP in human cocaine users and its influence on the safety and pharmacokinetics (PK) of cocaine. Twenty-four cocaine-using adult men were randomized to receive l-THP (30 mg twice a day orally) or placebo double-blind for 4 days, with an intranasal cocaine (40 mg) challenge on the fourth day. Safety and tolerability were evaluated using vital signs, ECG, clinical laboratory tests, and standardized self-report instruments. Peripheral venous blood was collected periodically and later assayed for l-THP and cocaine using highly sensitive and specific ultraperformance liquid chromatography-fluorescence detection (UPLC-FLD) methods. Twenty subjects completed the study, of whom 19 provided complete PK data. The short 3.5-day course of l-THP was safe and well tolerated and did not affect cocaine's PK or its acute cardiovascular effects. The cocaine AUC0→∞ was 211.5 and 261.4 h·ng/mL, and the Cmax was 83.3 and 104.5 ng/mL for the l-THP and placebo groups, respectively. In addition there were no significant differences in the number of side effects reported in each group (l-THP group 22 [48%], placebo group 24 [52%]) or vital signs including, heart rate, blood pressure, complete blood count, or ECG. These findings suggest that oral THP has promise for further development as a treatment for CUD.
