ABSTRACT

Drone brood homogenate is a little-known bee product used in folk medicine to treat various health problems. It is a very nutritious milky substance with high content of nutrients: proteins, lipids, fatty acids, carbohydrates, vitamins (A, B, E and D), and minerals. Moreover, when collected on early stage of larvae development, it is, most of all, rich source of sex hormone (testosterone, progesterone and estradiol). Some beekeepers consider drone brood as a waste product, although in some countries they use it to fight Varroa. Meanwhile, in many scientific reports a curative effect of bee drone homogenate in treating urgent global health problems have been confirmed, including ovarian dysfunction in women and male infertility, thyroid and immunity disorders, as well as malnutrition in children. A few dietary supplements based on drone brood are available online. Many patents relating to drone brood-based dietary supplements have been filed in Russia, but their prevalence in EU countries is still limited. Further research is needed to fully recognize the pharmacological activity and increase the use of drone brood.

ABSTRACT

BACKGROUND: Functional appliances has been used for treatment of skeletal Class II malocclusion for a long time; however, the real skeletal effects, mandibular growth particularly, remain insufficient. Several auxiliary approaches have been attempted with the hope of enhancing treatment effects. In this review, we summarize and discuss the use of additional nutrition and hormones to assist the functional appliance treatment on patients with skeletal Class II malocclusion. METHODS: Relevant articles were identified by electronic research in MEDLINE Ovid using keywords such as "nutrition," "hormone," "functional appliance," "orthodontics," "maxillofacial development," and "maxillofacial abnormalities." References of related articles were assessed for relevant studies to identify additional published references. RESULTS: The literature search yielded 239 studies. According to the current literature, use of additional nutrition and hormones, including growth hormones, sex hormones, insulin, and insulin-like growth factor I, seem to improve the effects of functional appliance treatment on patients with skeletal Class II malocclusion. CONCLUSIONS: The current evidence indicates that additional nutrition or hormones might improve the treatment effects on mandibular hypoplasia compared with the functional appliance alone, which is a promising approach and calls for further studies.

ABSTRACT

Background: Venous thromboembolism (VTE), ischemic stroke, and myocardial infarction in transgender persons may be related to hormone use. Objective: To examine the incidence of these events in a cohort of transgender persons. Design: Electronic medical record-based cohort study of transgender members of integrated health care systems who had an index date (first evidence of transgender status) from 2006 through 2014. Ten male and 10 female cisgender enrollees were matched to each transgender participant by year of birth, race/ethnicity, study site, and index date enrollment. Setting: Kaiser Permanente in Georgia and northern and southern California. Patients: 2842 transfeminine and 2118 transmasculine members with a mean follow-up of 4.0 and 3.6 years, respectively, matched to 48 686 cisgender men and 48 775 cisgender women. Measurements: VTE, ischemic stroke, and myocardial infarction events ascertained from diagnostic codes through the end of 2016 in transgender and reference cohorts. Results: Transfeminine participants had a higher incidence of VTE, with 2- and 8-year risk differences of 4.1 (95% CI, 1.6 to 6.7) and 16.7 (CI, 6.4 to 27.5) per 1000 persons relative to cisgender men and 3.4 (CI, 1.1 to 5.6) and 13.7 (CI, 4.1 to 22.7) relative to cisgender women. The overall analyses for ischemic stroke and myocardial infarction demonstrated similar incidence across groups. More pronounced differences for VTE and ischemic stroke were observed among transfeminine participants who initiated hormone therapy during follow-up. The evidence was insufficient to allow conclusions regarding risk among transmasculine participants. Limitation: Inability to determine which transgender members received hormones elsewhere. Conclusion: The patterns of increases in VTE and ischemic stroke rates among transfeminine persons are not consistent with those observed in cisgender women. These results may indicate the need for long-term vigilance in identifying vascular side effects of cross-sex estrogen.

ABSTRACT

INTRODUCTION: Pregnancy is associated with several hormonal changes which influence the developing fetus. Variations in maternal endogenous hormones and prepregnancy use of hormonal preparations have been linked to asthma and allergy in the offspring, but findings are inconsistent. We plan to undertake a systematic review to synthesise the evidence on the association between endogenous and exogenous maternal sex hormones and the risk of asthma and allergy in the offspring. METHODS AND ANALYSIS: We will search Medline, Embase, Cochrane Library, Institute of Scientific Information Web of Science, Cumulative Index of Nursing and Allied Health, Scopus, Google Scholar, Allied and Complementary Medicine Database, Global Health, Psychological Information (PsycINFO), Centre for Agriculture and Bioscience (CAB) International and WHO Global Health Library from inception until 2016 to identify relevant studies on the topic. Additional studies will be identified by searching databases of proceedings of international conferences, contacting international experts in the field and searching the references cited in identified studies. We will include analytical epidemiological studies. Two researchers will independently screen identified studies, undertake data extraction and assess risk of bias in eligible studies, while a third reviewer will arbitrate any disagreement. We will use the Effective Public Health Practice Project tool to assess the risk of bias in the studies. We will perform a random-effects meta-analysis to synthesise the evidence. We will use the Grading of Recommendations Assessment, Development and Evaluation approach to rate the strength and quality of the overall evidence with respect to each outcome. ETHICS AND DISSEMINATION: Ethical approval is not required since the study is a systematic review of published literature. Our findings will be reported in a peer-reviewed scientific journal. PROSPERO REGISTRATION NUMBER: CRD42016048324.

ABSTRACT

Transgender women (TW) represent a vulnerable population at increased risk for HIV infection in Peru. A mixed-methods study with 48 TW and 19 healthcare professionals was conducted between January and February 2015 to explore barriers and facilitators to implementing a model of care that integrates HIV services with gender-affirmative medical care (i.e., hormone therapy) in Lima, Peru. Perceived acceptability of the integrated care model was high among TW and healthcare professionals alike. Barriers included stigma, lack of provider training or Peruvian guidelines regarding optimal TW care, and service delivery obstacles (e.g., legal documents, spatial placement of clinics, hours of operation). The hiring of TW staff was identified as a key facilitator for engagement in health care. Working in partnership with local TW and healthcare provider organizations is critical to overcoming existing barriers to successful implementation of an integrated HIV services and gender-affirmative medical care model for this key population in Peru.

ABSTRACT

Fertility treatment strategies are evolving, with a more rapid transition to assisted reproductive technology (ART) treatments after unsuccessful non-ART treatments. This trend increases the potential importance of adjuvant treatments in non-ART cycles, such as steroid hormone supplementation. It has been established that success rates of ART treatments are increased with the use of luteal support with progesterone. In the setting of non-ART cycles, however, the evidence is less clear, and clinical practices vary widely between providers and clinics. In this review, we aimed to provide an overview of the current evidence for the use of steroid hormone supplementation, including progesterone for luteal support, estrogens, androgens, and mineralocorticoids, in the setting of non-ART treatments for ovulatory women.

ABSTRACT

Osteoporosis is defined by decreased bone density and microarchitectural deterioration that predispose to fragility fractures. The WHO diagnostic criteria of osteoporosis require bone densitometry but treatment is possible on the basis of high clinical fracture risk and can be assessed by the FRAX risk algorithm. All those subject to fracture risk should be advised about proper basic treatment of osteoporosis, including exercise, prevention of falls, smoking cessation, avoidance of alcohol intake, and dietary or supplemental abundance of calcium and vitamin D. Underlying diseases must be studied after diagnosis of osteoporosis even if treatment is initiated without densitometry. When indicated, specific osteoporosis therapy includes bisphosphonates, denosumab, teriparatide, strontium ranelate or SERMs. In hypogonadism, gonadal steroids may be indicated alone or in addition to a specific treatment. Treatment effect and continuation are assessed after 2 to 5 years.

ABSTRACT

Individuals with gender dysphoria experience distress associated with incongruence between their biologic sex and their identified gender. Gender dysphoric natal males receive treatment with antiandrogens and estrogens to become feminized (transsexual females), whereas natal females with gender dysphoria receive treatment with androgens to become masculinized (transsexual males). Because of the permanence associated with cross-sex hormone therapy (CSHT), adolescents diagnosed with gender dysphoria receive gonadotropin-releasing hormone analogs to suppress puberty. High rates of depression and suicide are linked to social marginalization and barriers to care. Behavior, emotional problems, depressive symptoms, and global functioning improve in adolescents receiving puberty suppression therapy. Gender dysphoria, psychological symptoms, quality of life, and sexual function improve in adults who receive CSHT. Within the first 6 months of CSHT, changes in transsexual females include breast growth, decreased testicular volume, and decreased spontaneous erections, and changes in transsexual males include cessation of menses, breast atrophy, clitoral enlargement, and voice deepening. Both transsexual females and males experience changes in body fat redistribution, muscle mass, and hair growth. Desired effects from CSHT can take between 3 and 5 years; however, effects that occur during puberty, such as voice deepening and skeletal structure changes, cannot be reversed with CSHT. Decreased sexual desire is a greater concern in transsexual females than in transsexual males, with testosterone concentrations linked to sexual desire in both. Regarding CSHT safety, bone mineral density is preserved with adequate hormone supplementation, but long-term fracture risk has not been studied. The transition away from high-dose traditional regimens is tied to a lower risk of venous thromboembolism and cardiovascular disease, but data quality is poor. Breast cancer has been reported in both transsexual males and females, but preliminary data suggest that CSHT does not increase the risk. Cancer screenings for individuals of both natal and transitioned sexes should occur as recommended. More long-term studies are needed to ensure that CSHT regimens with the best outcomes can continue to be prescribed for the transsexual population.

ABSTRACT

Long QT syndrome (LQTS) is an inherited disorder associated with life-threatening ventricular arrhythmias. An understanding of the relationship between the genotype and phenotype characteristics of LQTS can lead to improved risk stratification and management of this hereditary arrhythmogenic disorder. Risk stratification in LQTS relies on combined assessment of clinical, electrocardiographic, and mutations-specific factors. Studies have shown that there are genotype-specific risk factors for arrhythmic events including age, gender, resting heart rate, QT corrected for heart rate, prior syncope, the postpartum period, menopause, mutation location, type of mutation, the biophysical function of the mutation, and response to beta-blockers. Importantly, genotype-specific therapeutic options have been suggested. Lifestyle changes are recommended according to the prevalent trigger for cardiac events. Beta-blockers confer greater benefit among patients with LQT1 with the greatest benefit among those with cytoplasmic loops mutations; specific beta-blocker agents may provide greater protection than other agents in specific LQTS genotypes. Potassium supplementation and sex hormone-based therapy may protect patients with LQT2. Sodium channel blockers such as mexiletine, flecainide, and ranolazine could be treatment options in LQT3.

ABSTRACT

We have recently demonstrated that gonadal steroid hormones decrease formalin-induced temporomandibular joint nociception in rats. Given that the attenuation of inflammation is a potential mechanism underlying this antinociceptive effect, we evaluated the effect of gonadal steroid hormones on formalin-induced temporomandibular joint inflammation. Plasma extravasation, a major sign of acute inflammation, and neutrophil migration, an important event related to tissue injury, were evaluated. Formalin induced significantly lower temporomandibular joint plasma extravasation and neutrophil migration in proestrus females than in males and in diestrus females. Since estradiol serum level is high in proestrus females and low in diestrus females and in males, these findings suggest that the high physiological level of estradiol decreases temporomandibular joint inflammation. Estradiol but not progesterone administration in ovariectomized females significantly decreased formalin-induced plasma extravasation and neutrophil migration, an effect that was blocked by the estrogen receptor antagonist ICI 182780. Plasma extravasation and neutrophil migration were not affected by orchiectomy, but testosterone or estradiol administration in orchidectomized males significantly decreased them. The androgen receptor antagonist flutamide blocked the anti-inflammatory effect of testosterone while ICI 182780 blocked that of estradiol in males. Previous intravenous administration of a nonspecific selectin inhibitor significantly decreased formalin-induced temporomandibular joint nociception and neutrophil migration in males, revealing a potent and positive correlation between temporomandibular joint nociception and inflammation. Taken together, these findings demonstrate a pronounced anti-inflammatory effect of estradiol and testosterone in the temporomandibular joint region and suggest that this effect may mediate, at least in part, the antinociceptive effect of these hormones.

ABSTRACT

INTRODUCTION: Female sexual dysfunction (FSD) is a complex and multifactorial condition. An increased incidence of FSD is especially associated with the decline of estrogen. Thus, menopause is a critical phase for FSD complaints. In this context, medicinal plants may be a therapeutic option. AIM: To identify and describe the popular and clinical uses of medicinal plants for FSD treatment in climacteric women. We highlighted the majority of the plants commonly involved with the female reproductive system including: Angelica sinensis, Cimicifuga racemosa, Ferula hermonis, Ginkgo biloba, Humulus lupulus, Lepidium meyenii, Tribulus terrestris, Trifolium pratense, and Vitex agnus-castus. METHODS: This study is a narrative review of studies of plants that are possible alternative treatments for FSD. The species described have clinical and popular uses in different cultures as well as medical indications for female reproductive disturbances, mainly in climacteric women. We have also analyzed the evidence level of clinical studies. MAIN OUTCOME MEASURES: The main outcome assessed is the efficacy of plants in improving the symptoms of FSD. RESULTS: There is little evidence from the literature to recommend the use of medicinal plants when treating FSD. The majority of studies with a strong level of evidence are associated with the treatment of the vasomotor symptoms of menopause. Ferula hermonis, Angelica sinensis, and Gingko biloba may be suggested for arousal disorder studies. Cimicifuga racemosa, Trifolium pratense, and Vitex agnus-castus may be recommended for several FSD. Humulus lupulus and Tribulus terrestris may help with desire disorder studies. Lepidium meyenii should be studied further. CONCLUSIONS: Studies of these plants indicate that they may be useful as a possible alternative and/or complementary approach for studies aimed at the treatment of FSD. At this time, however, this review cannot recommend a plant that has a strong enough level of evidence for treatment of FSD. Thus, there is a need for clinical (double-blinded and randomized) studies to evaluate the efficacy and safety of several plants that can exert a positive effect on the management of FSD.

ABSTRACT

The pervasiveness of low bone mass (LBM) in beta-thalassemia (Thal) patients (pts) is escalating as the average life expectancy of these pts increases. Adolescence is a period of substantial bone accrual, which is crucial for future bone strength. Studies of LBM are prevalent among adults with Thal. However, limited information exists about bone accrual and LBM in adolescents with the disease. Thirty-one pts with beta-Thal (26 Thal major [TM], 5 Thal intermedia [TI]), aged 9-20 years (mean: 15.3 years), 14 males and 17 females, underwent measurement of spinal bone mineral density (BMD) by DEXA (Lunar, Prodigy). Height, weight, body mass index, and Tanner stage were assessed at the time of the BMD measurement. A total of 16.1% of the patients had normal bone mass (Z > or = -1), 22.6% had reduced bone mass (Z = -1 to -2), and 61.3% had low bone mass (Z < or = -2). BMD Z correlated with height and weight Z scores. Some 53.9% of subjects had normal gonadal function and 46.1% had induced puberty with gonadal steroids. BMD Z significantly worsened with age (P < .0001). However, there was no difference in the LBM prevalence between subjects with normal versus those with induced puberty: BMD Z was -2 or less in 71.4% of subjects with normal puberty versus 66.7% in those with induced puberty. Our results indicate a high prevalence of LBM among adolescents with Thal regardless of adequate transfusion and chelation regimens. Bone accrual was found to be suboptimal in adolescents with normal or induced puberty. Thus, calcium and vitamin D supplementation with antiresorptive therapies should be evaluated in the adolescent Thal pt with close monitoring of growth and sexual development.

ABSTRACT

BACKGROUND: In Germany, there is a lack of population-based data related to the use of gynaecological health care services. The objectives of our analyses utilizing a population-based cross-sectional survey conducted in one geographically defined area [Study of Health in Pomerania (SHIP)] are to assess the prevalences of: (i) attendance of gynaecological outpatient facilities and of (cervical) cancer screening; (ii) gynaecological and breast surgery; (iii) use of oral contraceptives (OC) and menopausal hormone therapy (MHT). METHODS: We analysed socio-demographic factors, reproductive history, gynaecological service utilization, and use of sex hormones in 2186 women aged 20-79 years. We used standard statistics and sex- and age group-specific weighting factors to reflect characteristics of the population of Western Pomerania. RESULTS: Approximately 43% of women reported surgical procedures. Participation in cancer screening at least once was reported by 78% of women (lifetime prevalence). Two-thirds of women stated ever use of OC, 28% (aged >40 years) ever use of MHT. CONCLUSIONS: Women in Western Pomerania reported a high life-time use of both OC and MHT. The use of cervical cancer screening exceeded the national average. Women had an almost 50% risk of undergoing gynaecological, breast or obstetric surgery. The high use of MHT and surgical procedures calls for efforts regarding continuing medical education and health care policy actions.

ABSTRACT

Deficiency of the weak androgen dehydroepiandrosterone (DHEA) and its sulfoconjugated metabolite DHEA-S has been associated with a number of serious illnesses, including lupus, diabetes, Alzheimer's disease and some cancers. Accordingly, supplementation with DHEA has been proposed for a variety of illnesses. Observational clinical studies and in vitro experiments have suggested that DHEA treatment might have a significant impact on immunological function, bone density, cognition, atherosclerotic disease, some malignancies, insulin resistance and obesity. Endogenous circulating DHEA levels, however, may vary widely by gender, age and ethnicity and can be affected by acute changes in corticosteroid production, alcohol intake, smoking, body mass index, medications and thyroid function [1-3]. Clearly, these variables complicate the interpretation of clinical data. DHEA also gives rise to a number of as yet poorly characterised metabolites, further confusing the assessment of its net effects when considered as treatment in heterogenous populations. Given the complexity of potential effects of DHEA and its metabolites, coupled to the diversity of clinical conditions that they might, at least in theory, affect, it is not surprising that clinical confirmation of efficacy in several clinical contexts has been inconsistent and controversial, hampering drug development in what might potentially be an important and widespread market. The current review will consider recent work suggesting efficacy of DHEA (GL-701, prasterone, Prestara( trade mark ) [US], Anastar( trade mark ) [Europe]; Genelabs) in systemic lupus erythematosus.

ABSTRACT

Periods of intense hormonal fluctuations have been associated with heightened prevalence and exacerbation of underlying psychiatric illness, particularly the occurrence of premenstrual dysphoria, puerperal depression and depressive symptoms during perimenopause. It has been speculated that sex steroids such as estrogens, progestogens, testosterone and dehydroepiandrosterone (DHEA) exert a significant modulation of brain functioning, possibly through interactions with various neurotransmitter systems. It is therefore intuitive that abrupt alterations of these hormones would interfere with mood and behaviour. On the other hand, accumulating data suggest that hormonal interventions may also promote relief or even remission of depressive symptoms, as already demonstrated in studies with patients experiencing postpartum depression and perimenopausal depressive disorders. The extent to which perimenopause, alone, may increase the risk for depression is unclear. However, existing data strongly suggest that some women are particularly vulnerable to developing significant physical and psychological disturbances when entering perimenopause. This article reviews the effect of sex hormones and selective estrogen receptor modulators (SERMs) on mood among peri- and postmenopausal women. There are preliminary, though promising, data on the use of estradiol (particularly transdermal estradiol) to alleviate depression during perimenopause, use of a combination of estrogens and selective serotonin reuptake inhibitors for depression during the postmenopausal period, and the use of testosterone to improve psychological well-being and increase libido among women with induced menopause. Further studies would help to better delineate the usage of hormones as an antidepressant strategy (monotherapy or augmenting treatment) for peri- and postmenopausal women. A brief review of some nonhormonal interventions for the treatment of menopause-related symptoms that may significantly affect a woman's quality of life is also presented. There are some preliminary data suggesting the efficacy of antidepressants for the treatment of hot flushes; existing data on diet supplements and herbal products have shown more mixed results.

ABSTRACT

Serum testosterone levels decline gradually and progressively with aging in men. Many manifestations associated with aging in men, including muscle atrophy and weakness, osteoporosis, reduced sexual functioning, and increased fat mass, are similar to changes associated with testosterone deficiency in young men. These similarities suggest that testosterone supplementation may prevent or reverse the effects of aging. A MEDLINE search was performed to identify studies of testosterone supplementation therapy in older men. A structured, qualitative review was performed of placebo-controlled trials that included men aged 60 and older and evaluated one or more physical, cognitive, affective, functional, or quality-of-life outcomes. Studies focusing on patients with severe systemic diseases and hormone deficiencies related to specific diseases were excluded. In healthy older men with low-normal to mildly decreased testosterone levels, testosterone supplementation increased lean body mass and decreased fat mass. Upper and lower body strength, functional performance, sexual functioning, and mood were improved or unchanged with testosterone replacement. Variable effects on cognitive function were reported, with improvements in some cognitive domains (e.g., spatial, working, and verbal memory). Testosterone supplementation improved exercise-induced coronary ischemia in men with coronary heart disease, whereas angina pectoris was improved or unchanged. In a few studies, men with low testosterone levels were more likely to experience improvements in lumbar bone mineral density, self-perceived functional status, libido, erectile function, and exercise-induced coronary ischemia with testosterone replacement than men with less marked testosterone deficiency. No major unfavorable effects on lipids were reported, but hematocrit and prostate specific antigen levels often increased. Based on these results, testosterone supplementation cannot be recommended at this time for older men with normal or low-normal testosterone levels and no clinical manifestations of hypogonadism. However, testosterone replacement may be warranted in older men with markedly decreased testosterone levels, regardless of symptoms, and in men with mildly decreased testosterone levels and symptoms or signs suggesting hypogonadism. The long-term safety and efficacy of testosterone supplementation remain uncertain. Establishment of evidence-based indications will depend on further demonstrations of favorable clinical outcomes and symptomatic, functional, and quality-of-life benefits in carefully performed, long-term, randomized, placebo-controlled clinical trials.

ABSTRACT

This article presents a literature review on the risk factors for oral clefts (lip and/or palate), emphasizing discussion of maternal exposure to endocrine disruptors. Several studies have identified the risk of cigarette smoking and alcohol consumption, use of anticonvulsant drugs, and exposure to organic solvents. A protective effect has been shown for supplementation with folic acid. As with other chemicals, the risk associated with exposure to sex hormones is still obscure, although some authors describe a moderate risk level. New studies addressing this hypothesis need to be conducted, while the population exposed to these endocrine disrupters is increasing.

ABSTRACT

A progressive decrease in androgen production is common in aging men. The physiological causes for this phenomenon seem to be multifactorial. The magnitude of the decline in testosterone with age and the prevalence of older men with low testosterone levels have not been well established. The extent to which an age-dependent decline in androgen levels leads to health problems that might affect or alter the quality of life remains under debate. In men older than middle age, total testosterone levels may be misleading because of an increase in sex hormone-binding globulin levels. The mechanism of the age-associated decrease of the endocrine testicular function is also essentially due to primary testicular failure, but important changes occur at the hypothalamopituitary level. The most prominent endocrinological alterations with aging are related to the sex steroids, but others, such as growth hormone, melatonin cortisol, and thyroxine, are also affected. The clinical picture of andropause syndrome is characterized by diminished sexual desire and erectile capacity, decrease in intellectual activity, fatigue, depression, decrease in lean body mass, skin alterations, decrease in body hair, decrease in bone mineral density that results in osteoporosis, and increase in visceral fat and obesity. Current medical treatments for androgen supplementation include oral tablets, intramuscular injections, and scrotal and nonscrotal patches. Unfortunately, none of these preparations mimic the circadian rhythm, even if some of them may approximate the circadian rhythm by dose adjustments. Moreover, the androgen supplementation could have adverse effects on different organs, namely, the liver, lipid profile, cardiovascular disease, prostate, sleep disorders, and emotional behavior. Clinical response is a better guide to dose requirements, regardless of serum testosterone levels. This important field must be actively investigated by the medical, behavioral, and social sciences.

ABSTRACT

OBJECTIVE: To determine whether glucocorticoid-induced osteoporosis in male veterans was managed in accordance with American College of Rheumatology (ACR) guidelines. These guidelines recommend bone mineral density (BMD) determination at the initiation of long-term therapy with prednisone > or =7.5 mg/d, provision of hormone replacement therapy as needed, calcium and vitamin D supplementation as necessary, and antiresorptive therapy for low BMD. DESIGN: Patients receiving prednisone > or =7.5 mg/d throughout a predefined six-month period were identified through a hospital pharmacy database. Electronic and paper chart review was carried out to determine whether BMD measurement by dual-energy X-ray absorptiometry had been performed. Supplemental calcium and vitamin D intake was assessed for each patient. In addition, pharmacy records were reviewed to determine whether antiresorptive therapy was prescribed for patients with low BMD. SETTING: The Wm. S. Middleton Veterans Affairs Medical Center, Madison, WI. RESULTS: Seventy-two men met study criteria. They had been receiving oral prednisone treatment for a median of 30 months (range 6-74); mean daily dosage during the six-month study period was 12.5 mg (range 7.5-37.5). Extensive record review revealed that only six patients (8%) received recommended calcium and vitamin D, and only 43 (60%) had a BMD determination. Of those 43 men, 32 had T-scores below -1, therefore meeting ACR criteria for recommended antiresorptive therapy. However, only 12 of these 32 patients were prescribed antiresorptive therapy. Although this study was not designed to evaluate differences among clinics, there appeared to be better adherence to ACR guidelines for patients cared for in a rheumatology specialty clinic than in other clinics at the institution. CONCLUSIONS: Adherence to ACR guidelines for management of glucocorticoid-induced osteoporosis was poor. Efforts to improve the prevention and management of glucocorticoid-induced osteoporosis in male veterans are warranted.
