What Potentially Modifiable Factors are Associated With Treatment Nonadherence in Pediatric Growth Hormone Deficiency? A Quantitative Study

ObjectiveA recent systematic review reported that up to 71% of patients with growth hormone deficiency and their families are nonadherent to treatment as prescribed. Nonadherence to growth hormone treatment presents a substantial and costly problem for the patient, health care provider, and health care system. The current study uniquely investigated the potentially modifiable factors associated with treatment nonadherence in this endocrine disorder.MethodsThe cross-sectional study was conducted among 82 parent/caregivers of children with growth hormone deficiency who were receiving growth hormone treatment. Self-report questionnaires investigated parent/caregiver perceptions and experiences of their child’s condition and prescribed treatment, in addition to their perceived relationship with their health care professional. The 8-item Morisky medication adherence scale was used for the assessment of treatment adherence.ResultsSixty-two percent of parents/caregivers were found to be nonadherent to growth hormone treatment as prescribed. Illness perceptions (consequences, identity, and coherence) and treatment concerns were found to be significantly associated with treatment adherence, as was the quality of the health care professional–parent/caregiver relationship.ConclusionThe study confirmed the extent of the adherence problem evident among the pediatric growth hormone deficiency population. In addition, it presented an insight into the explanatory factors that underpin nonadherence to growth hormone treatment. Our findings can be used to inform the development of adherence-focused interventions, with the purpose of supporting patients and their families and improving the use of prescribed growth hormone treatment within endocrine clinical practice.     

American Association of Clinical Endocrinology Consensus Statement: Addressing Stigma and Bias in the Diagnosis and Management of Patients with Obesity/Adiposity-Based Chronic Disease and Assessing Bias and Stigmatization as Determinants of Disease Severity

ObjectiveTo focus on the intersection of perception, diagnosis, stigma, and weight bias in the management of obesity and obtain consensus on actionable steps to improve care provided for persons with obesity.MethodsThe American Association of Clinical Endocrinology (AACE) convened a consensus conference of interdisciplinary health care professionals to discuss the interplay between the diagnosis of obesity using adiposity-based chronic disease (ABCD) nomenclature and staging, weight stigma, and internalized weight bias (IWB) with development of actionable guidance to aid clinicians in mitigating IWB and stigma in that context.ResultsThe following affirmed and emergent concepts were proposed: (1) obesity is ABCD, and these terms can be used in differing ways to communicate; (2) classification categories of obesity should have improved nomenclature across the spectrum of body mass index (BMI) using ethnic-specific BMI ranges and waist circumference (WC); (3) staging the clinical severity of obesity based on the presence and severity of ABCD complications may reduce weight-centric contribution to weight stigma and IWB; (4) weight stigma and internalized bias are both drivers and complications of ABCD and can impair quality of life, predispose to psychological disorders, and compromise the effectiveness of therapeutic interventions; (5) the presence and of stigmatization and IWB should be assessed in all patients and be incorporated into the staging of ABCD severity; and (6) optimal care will necessitate increased awareness and the development of educational and interventional tools for health care professionals that address IWB and stigma.ConclusionsThe consensus panel has proposed an approach for integrating bias and stigmatization, psychological health, and social determinants of health in a staging system for ABCD severity as an aid to patient management. To effectively address stigma and IWB within a chronic care model for patients with obesity, there is a need for health care systems that are prepared to provide evidence-based, person-centered treatments; patients who understand that obesity is a chronic disease and are empowered to seek care and participate in behavioral therapy; and societies that promote policies and infrastructure for bias-free compassionate care, access to evidence-based interventions, and disease prevention.     

Attitudes,Perceptions, and Practices Among Endocrinologists Managing Obesity

ObjectiveObesity has been globally recognized as a critically important disease by professional medical organizations, in addition to the World Health Organization and American Medical Association, but health care systems, medical teams, and the public have been slow to embrace this concept.MethodsThe American Association of Clinical Endocrinology staff drafted a survey, and 2 endocrinologists independently reviewed the survey’s questions and modified the survey instrument. The survey included questions related to practice and patient demographics, awareness about obesity, treatment of obesity, barriers to improving obesity outcomes, digital health, cognitive behavioral therapy, lifestyle medicine, antiobesity medications, weight stigma, and social determinants of health. The survey was emailed to 493 endocrinologists, with 305 (62%) completing the study.ResultsOf the responders, 98% agreed that obesity is a disease, whereas 2% neither agreed nor disagreed. Of the respondents, 53% were familiar with the term “adiposity-based chronic disease” and 13% were certified by the American Board of Obesity Medicine. Of the respondents, 57% used published obesity guidelines as a resource for treating patients with obesity. Most endocrinologists recommended dietary and lifestyle changes, but fewer prescribed an antiobesity medication or recommended bariatric surgery. American Board of Obesity Medicine-certified endocrinologists were more likely to use a multidisciplinary approach.ConclusionSelf-reported knowledge and practices in the management of obesity highlight the importance of a multimodal approach to obesity and foster collaboration among health care professionals. It is necessary to raise awareness about obesity among clinicians, identify knowledge gaps, and create educational tools to address those gaps.     

Minimizing Venous Thromboembolism in Feminizing Hormone Therapy: Applying Lessons From Cisgender Women and Previous Data

ObjectiveTo review he impact of estrogen-containing feminizing hormone regimens on transgender individuals’ risk for VTE.MethodsWe evaluated VTE risk by screening 1170 relevant studies published from 1994 to 2020, focusing on meta-analysis data.ResultsThe type of oral estrogen, route of administration, patient demographics, and comorbidities may affect the risk of VTE. Venous thrombosis is the most common vascular complication associated with HT.ConclusionConjugated equine estrogens and 17-β estradiol appear to be safer than oral ethinyl estradiol. Transdermal estrogen formulations appear to be the least thrombogenic estrogens. Estrogens used concomitantly with progestins increase the risk of VTE compared to estrogens alone.To date, there are no data to demonstrate the benefit of holding HT prior to vaginoplasty or other gender affirming surgeries. For most young, healthy transgender women, there is little risk of VTE with HT, while older patients with risk factors should be discussed case by case.     

Desmopressin Suppresses Gonadotropin-Induced Spermatogenesis in Patients With Pituitary Stalk Interruption Syndrome: A Retrospective,Single-Center Cohort Study

ObjectiveTo explore the influence of desmopressin on gonadotropin-induced spermatogenesis in patients with pituitary stalk interruption syndrome (PSIS).MethodsA single-center retrospective cohort study was conducted. All patients with PSIS had both gonadotropin and growth hormone (GH) deficiency. Patients were divided into desmopressin and nondesmopressin groups. The desmopressin and nondesmopressin groups were defined by the presence or absence of central diabetes insipidus, which determined whether the patient received desmopressin or not.ResultsThe average age of gonadotropin therapy was 24.3 and 26.1 in the desmopressin and nondesmopressin groups, respectively. The rate of successful spermatogenesis in the 2 groups was 31.58% and 77.27%, respectively. The period for first sperm appearance was 13.62 ± 5.95 and 13.48 ± 6.69 months, respectively. A multivariable Cox proportional hazards model found that the adjusted hazard ratio for desmopressin was 0.260, indicating a “possible” detrimental effect of desmopressin on spermatogenesis. Central diabetes insipidus would be expected to show a similar detrimental effect. The spermatogenesis rate decreased with increased dosage of desmopressin. In the nondesmopressin group, the rate of spermatogenesis was similar between the GH group and the non-GH subgroup. The GH group had higher sperm count and concentration than the non-GH group.ConclusionA minority of patients with PSIS had mild diabetes insipidus and received desmopressin therapy. The spermatogenesis rate decreased with increasing desmopressin dosage. In addition, GH supplementation did not affect the spermatogenesis rate.     

Withdrawal of Denosumab in Patients With Primary Hyperparathyroidism: A Follow-up Report of the DENOCINA Study

ObjectivesWe investigated the development in the primary outcomes: changes in bone mineral density (BMD) measured by dual x-ray absorptiometry at the lumbar spine, total hip, and femoral neck after 2 years.MethodsIn patients with primary hyperparathyroidism, we investigated the effects of 30-mg cinacalcet per day plus 60 denosumab every 6 months for 1 year (Deno group), versus denosumab plus placebo for 1 year (DenoPlacebo-group), versus placebo plus placebo injection for 1 year (Placebo group). After the study’s termination, most patients receiving denosumab were switched to bisphosphonate treatment.ResultsForty-three out of 45 participants were subject to follow-up. A total of 35 patients completed a 2-year follow-up dual x-ray absorptiometry-scan (Deno: n = 13; DenoPlacebo: n = 12; and Placebo: n = 10). None of the groups showed statistically significant changes in BMD or experienced decreases in mean BMD below the study’s baseline level. Overall, the changes in T-scores from the final study measurement to follow-up were similar among the groups (P = .38 for lumbar spine T-score, .63 for total hip, and .97 for femoral neck by 1-way ANOVA). P-calcium was not different over time (P = .20 for change over time and P = .08 for the difference between the groups by repeated measures ANOVA). A total of 5 participants suffered a fracture during the study or follow-up periods, all but one was in the placebo group.ConclusionEvidence suggests that it is possible to at least maintain BMD, and thus potentially lower the fracture risk by a short course of denosumab followed by antiresorptive therapy, where applicable in patients with primary hyperparathyroidism.     

Patient Understanding of Discharge Instructions for Home Diabetes Self-Management and Risk for Hospital Readmission and Emergency Department Visits

ObjectiveThe primary objective of this study was to examine the patient comprehension of diabetes self-management instructions provided at hospital discharge as an associated risk of readmission.MethodsNoncritically ill patients with diabetes completed patient comprehension questionnaires (PCQ) within 48 hours of discharge. PCQ scores were compared among patients with and without readmission or emergency department (ED) visits at 30 and 90 days. Glycemic measures 48 hours preceding discharge were investigated. Diabetes Early Readmission Risk Indicators (DERRIs) were calculated for each patient.ResultsOf 128 patients who completed the PCQ, scores were similar among those with 30-day (n = 31) and 90-day (n = 54) readmission compared with no readmission (n = 72) (79.9 ± 14.4 vs 80.4 ± 15.6 vs 82.3 ± 16.4, respectively) or ED visits. Clarification of discharge information was provided for 47 patients. PCQ scores of 100% were achieved in 14% of those with and 86% without readmission at 30 days (P = .108). Of predischarge glycemic measures, glycemic variability was negatively associated with PCQ scores (P = .035). DERRIs were significantly higher among patients readmitted at 90 days but not 30 days.ConclusionThese results demonstrate similar PCQ scores between patients with and those without readmission or ED visits despite the need for corrective information in many patients. Measures of glycemic variability were associated with PCQ scores but not readmission risk. This study validates DERRI as a predictor for readmission at 90 days.     

Preference of sweeteners among Saudi diabetes patients from a tertiary health care centre in Riyadh,Saudi Arabia

BackgroundChoice of sweetening options can influence glyceamic control among patients with diabetes. This study aims to investigate the preference of added sweeteners for Saudi patients with diabetes, factors associated with the choice of sweeteners and the attitude of the patients towards the use of artificial sweeteners.MethodsThis was a cross-sectional study conducted at King Saud University Medical City in Riyadh, Saudi Arabia and targeting Saudi patients with type 2 diabetes mellitus. Data was collected via personal interviews accessing medical records of interviewed patients. Patients were asked about consumption of sweeteners and types of consumed soft drinks on daily basis. Bi-variate analysis of the associations between choice of sweeteners and patients characteristics was performed and followed by binary logistic regression to adjust for potential confounders such as age, gender, and education level.ResultsA total of 302 Saudi diabetic patients were recruited in this investigation. Among this sample, frequency of patients reporting weekly consumption of white sugar was the highest (57%), followed by honey (26%) and artificial sweeteners (12% for powder form and 10.5% for tablets). Consumption of white sugar was significantly more frequent among patients with higher level of Body Mass Index (BMI) (P value < 0.05). The frequency of using honey was higher among females while consumption of either sugared or low calorie soft drinks was significantly higher among male patients (P values < 0.05). Upon asking the patients about their attitude towards artificial sweeteners, only 25% of the sample agreed that their use can aid in reduction of caloric intake while 35% of the sample agreed that artificial sweeteners can be harmful to the body.ConclusionsAmong this sample of type 2 diabetes patients, the frequency of white sugar and honey use as a sweetening option is high. These findings generate the need for further research to investigate the effectiveness of health education and nutritional advice among diabetes patients attending similar clinical settings in Saudi Arabia.     

Flash Glucose Monitoring Compared to Capillary Glucose Levels in Patients With Diabetic Ketoacidosis: Potential Clinical Applications

ObjectiveFrequent, finger-prick capillary blood glucose measurement is standard care, used to drive insulin infusion rates for inpatients being resuscitated from diabetic ketoacidosis (DKA). Over recent years there has been a shift toward continuous interstitial glucose monitoring, allowing monitoring of glucose without repeated invasive testing. While continuous interstitial glucose monitoring has been safely and reliably utilized in the outpatient setting, it has yet to be studied in acutely unwell patients with DKA. The aim of this study, allowing for physiologically lower interstitial compared to capillary glucose, was to determine if interstitial flash glucose monitoring (FGM) would lead to insulin infusion rates that were similar to capillary blood glucose (CapBG) in DKA.MethodsIn this study, 10 patients with diabetes mellitus, assessed to be in DKA, were enrolled. At the same time as standard DKA management commencement, simultaneous FGM measurements were obtained. Duplicate paired glucose readings were then analyzed for agreement.ResultsActual (CapBG-driven) and predicted (FGM determined) insulin infusion rates were similar. Minor differences in predicted insulin infusion rates were noted in 2/10 patients at higher glucose concentrations, which may relate to the lag in change in glucose in the interstitial space.ConclusionBased on our results, a trial of clinical outcomes in patients with DKA treated with insulin infusion rates driven by CapBG versus subcutaneous FGM appears justified. The FGM method of testing may improve patient comfort, obviate fatigue, improve staff time and direct patient contact, and potentially facilitate rapid discharge.     

Assessing and Addressing the Risk of Venous Thromboembolism Across the Spectrum of Gender Affirming Care: A Review

ObjectiveAccumulating evidence demonstrates that gender affirming hormone therapy (GAHT) improves mental health outcomes in transgender persons. Data specific to the risks associated with GAHT for transgender persons continue to emerge, allowing for improvements in understanding, predicting, and mitigating adverse outcomes while informing discussion about desired effects. Of particular concern is the risk of venous thromboembolism (VTE) in the context of both longitudinal GAHT and the perioperative setting. Combining what is known about the risk of VTE in cisgender individuals on hormone therapy (HT) with the evidence for transgender persons receiving HT allows for an informed approach to assess underlying risk and improve care in the transgender community.ObservationsHormone formulation, dosing, route, and duration of therapy can impact thromboembolic risk, with transdermal estrogen formulations having the lowest risk. There are no existing risk scores for VTE that consider HT as a possible risk factor. Risk assessment for recurrent VTE and bleeding tendencies using current scores may be helpful when assessing individual risk. Gender affirming surgeries present unique perioperative concerns, and certain procedures include a high likelihood that patients will be on exogenous estrogens at the time of surgery, potentially increasing thromboembolic risk.Conclusions and RelevanceWithholding GAHT due to potential adverse events may cause negative impacts for individual patients. Providers should be knowledgeable about the management of HT in transgender individuals of all ages, as well as in the perioperative setting, to avoid periods in which transgender individuals are off GAHT. Treatment decisions for both anticoagulation and HT should be individualized and tailored to patients’ overall goals and desired outcomes, given that the physical and mental health benefits of gender affirming care may outweigh the risk of VTE.     

Are patients affected by chronic non-communicable diseases aware of their own clinical and laboratory parameters? A cross-sectional study from the south of Saudi Arabia

BackgroundPatient’s awareness of their clinical and laboratory parameters is an indicator of the degree of involvement in achieving their management goals. This investigation aimed to identify awareness of patients affected by chronic non-communicable diseases of their clinical and laboratory parameters and factors associated with the awareness.MethodsThis study was a cross-sectional investigation conducted in the Jazan region, between January and August 2020. Data was collected during phone interviews utilizing a semi-structured questionnaire. Odds ratios (ORs) were calculated to estimate the likelihood of awareness of each clinical and laboratory parameter according to the measured demographic variables.ResultsThe total number of recruited patients was 675. The mean age of participants was 53.7 years and the 28.7% of patients were illiterate. About 17% of the patient do not attend follow-up visits to any healthcare provider. When patients were asked about their parameters, 87% of them were able to report their body weight and 74% were able to report their height. However, less than half of patients were aware of their glycated hemoglobin level (HbA1c) (271/675 patients) and systolic blood pressure (BP) level (329/ 675 patients), and a minority were aware of their total cholesterol level (71/675 patients). Being female, resident in a rural area, illiterate, and older than 53 was strongly associated with high odds of limited awareness about their own clinical and laboratory parameters (P values < 0.05).ConclusionAwareness of patients affected by chronic non-communicable diseases of their own clinical and laboratory parameters in the Jazan region is sub-optimal where this limited awareness is likely to be associated with the lower engagement of patients with achieving their desired management targets.     

Health Benefit Costs and Absenteeism Among Employed Patients With Acromegaly

ObjectiveAcromegaly is associated with increased morbidity and mortality. Limited data are available on these patients’ utilization and costs of health care. This study assessed the impact of acromegaly on employees’ health benefit (direct and indirect) costs and absenteeism.MethodsA retrospective analysis was conducted of drug and medical claims and employer data (from January 2010 to April 2019) of patients with an acromegaly diagnosis and matched controls from a U.S. employee database. Patient claims were tracked for 12 months postdiagnosis (or matched) date. Outcomes were analyzed using separate 2-part regression models, controlling for clinical, demographic, and job-related variables.ResultsForty-seven patients with acromegaly and 940 controls were identified. Cohorts were similar in most demographic and job-related variables. Patients with acromegaly had a significantly higher Charlson comorbidity index score and higher incidence of claims for several comorbidities. Acromegaly drugs represented 16.3% of the acromegaly cohort’s total costs. Total health benefit costs were $54 821 higher (P < .05) for patients compared with controls, with direct costs representing 79.8% of the difference. Total indirect costs were higher for patients with acromegaly, with short-term and long-term disability comprising most of the difference between the acromegaly and control groups. Patients with acromegaly had significantly more short-term disability days than controls, but total sick days were similar for the 2 groups.ConclusionThe presence of acromegaly was associated with increased direct and indirect employee health benefit costs and increased work absenteeism.     

Predictors of Prolonged Euthyroidism After Radioactive Iodine Treatment for Graves’ Disease: A Pilot Study

ObjectivePatients with Graves’ disease who remain hyperthyroid under the treatment of antithyroid drugs (ATD) or cannot tolerate ATD usually receive radioactive iodine (RAI) to control disease activity. This pilot study aimed to identify predictors of prolonged euthyroidism > 12 months after receiving RAI.MethodsDemographic, clinical, and laboratory data from 117 patients receiving RAI were retrospectively collected, including age, gender, body surface area, smoking status, free thyroxine, thyrotropin, thyrotropin binding inhibiting immunoglobulin, microsomal antibody, thyroglobulin antibody, medication history, and thyroid volume. Only 85 patients without missing values were included in statistical analysis. The calculated RAI dose was the estimated thyroid volume × 0.4. The difference and ratio between the actual and calculated RAI doses were examined. A stepwise logistic regression analysis was conducted to identify important predictors of prolonged euthyroidism > 12 months. The cut-off values for discretizing continuous covariates were estimated by fitting generalized additive models.ResultsAmong the 85 patients on RAI, 18 (21.2%) achieved prolonged euthyroidism > 12 months, 38 (44.7%) remained hyperthyroid with decreased ATD doses, but 29 (34.1%) suffered permanent hypothyroidism and needed long-term levothyroxine. Logistic regression analysis revealed that patients with age > 66 years, 33 < age ≤ 66 years, quitting smoking vs nonsmoking or current smoking, 600 < micorsomal antibody ≤ 1729 IU/mL, 47% < thyrotropin binding inhibiting immunoglobulin ≤ 81%, 7 < thyroglobulin antibody ≤ 162 IU/mL, 0.63 < ratio between actual and calculated RAI doses ≤ 1.96, or taking hydroxychloroquine would have a higher chance of reaching prolonged euthyroidism > 12 months after receiving RAI. Its area under the Receiver Operating Characteristic (ROC) curve was 0.932.ConclusionPatients with Graves’ disease who received an actual RAI dose close to the calculated RAI dose achieved prolonged euthyroidism > 12 months if they also took hydroxychloroquine during RAI treatment.     

Arterial Stiffness,Carotid Intima-Media Thickness,Endocan, and A Disintegrin and Metalloproteinase With Thrombospondin Type I Motif 9 Levels and Their Relationship With Disease Activity in Patients With Acromegaly With and Without Cardiovascular Risk Factors

ObjectiveCardiovascular complications such as cardiomyopathy and endothelial dysfunction, which are frequently seen in patients with acromegaly, are among the most important causes of morbidity and mortality. In this study, we aimed to investigate arterial stiffness, carotid intima-media thickness, endocan level, and A disintegrin and metalloproteinase with thrombospondin type I motif 9 level and their relationship with disease activity in patients with acromegaly with and without cardiovascular risk factors.MethodsA total of 60 patients with acromegaly—25 with active disease, 26 with well-controlled disease, and 9 with newly diagnosed disease—and 60 age-, sex-, and body mass index (BMI)-matched healthy control subjects were enrolled in this study. All the subjects’ height, weight, BMI, systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting plasma glucose (FPG) level, insulin, hemoglobin A1C (HbA1C), C-reactive protein , lipid, endocan, A disintegrin and metalloproteinase with thrombospondin type I motif 9 levels, pulse wave velocity (PWV), and carotid intima-media thickness were measured.ResultsThe SBP, DBP, FPG level, HbA1C level, and PWV of the acromegaly group were higher than those of the control group. In patients with acromegaly with cardiovascular disease (CVD) risk factors, the PWV was higher than that in the control group, and in patients with acromegaly without CVD risk factors, the PWV was similar to that in the control group. In a correlation analysis, a positive correlation was found between PWV and age, BMI, SBP, DBP, FPG level, and HbA1C level in the acromegaly group.ConclusionIn our study, we found that arterial stiffness increased in patients with acromegaly with CVD risk factors and that increased arterial stiffness was associated with hemodynamic (SBP and DBP) and metabolic (BMI, FPG level, and HbA1C level) parameters.     

Preoperative Calcium and Parathyroid Hormone Values Are Poor Predictors of Gland Volume and Multigland Disease in Primary Hyperparathyroidism: A Review of 2000 Consecutive Patients

ObjectiveCalcium and parathyroid hormone (PTH) values are believed to have a linear relationship in patients with primary hyperparathyroidism and correlate with parathyroid gland size, with higher values predicting single-gland disease. In this modern series, these preoperative values were correlated with operative findings to determine their utility in predicting the gland involvement at parathyroid exploration.MethodsTwo thousand consecutive patients who underwent initial surgery for sporadic primary hyperparathyroidism from 2000 to 2014 were reviewed. All patients underwent a 4-gland exploration. Relationships between preoperative calcium and PTH values with the total gland volume of each patient were examined and stratified using the number of involved glands: single adenoma (SA), double adenoma (DA), and hyperplasia (H).ResultsThere were 1274 (64%) SA, 359 (18%) DA, and 367 (18%) H cases. There was a poor correlation between preoperative calcium and PTH values (R = 0.37) and both poorly correlated with the total gland volume (R < 0.40). Similarly, subgroup analysis using the number of involved glands showed poor correlation. The mean total gland volume was similar among all subgroups (SA = 1.28 cm³, DA = 1.43 cm³, and H = 1.27 cm³; P = .52), implying that individual glands were smaller in multigland disease. SA was found in 271 (53%) of patients with calcium levels of ≤10.5 mg/dL and 122 (78%) with levels of ≥12 mg/dL (P < .001).ConclusionThis is the largest series correlating preoperative calcium and PTH values with operative findings of gland size and number of diseased glands. Although a lower calcium value predicts somewhat more multigland disease, the overall poor correlation should make the parathyroid surgeon aware that gland size and multigland disease cannot be predicted by preoperative laboratory testing.     

Desensitization to Methimazole

ObjectiveThionamides (methimazole and propylthiouracil) have been associated with common side effects, such as rash and pruritus, and rare but serious adverse effects, such as agranulocytosis and hepatotoxicity. Methimazole is usually the preferred thionamide for the treatment of hyperthyroidism if the patient is not planning to conceive or not in the first trimester of pregnancy, given the less frequent dosing and lower risk of hepatotoxicity. In patients who experience rash or itching when treated with methimazole, switching them to propylthiouracil is one treatment option. Here we report our experience regarding desensitization to methimazole to allow continued treatment with methimazole as an alternative management option.MethodsWe conducted a retrospective chart review of patients at a single institution who had side effects to methimazole and who were desensitized to methimazole under the supervision of an allergist. A total of 7 patients were included who experienced side effects to methimazole that did not include agranulocytosis or hepatotoxicity.ResultsAll 7 patients were able to take methimazole for treatment of their hyperthyroidism, either for continued medical therapy or as a bridge to definitive therapy, with either surgery or radioactive iodine treatment.ConclusionUnder the supervision of an allergist, desensitization to methimazole is an option for treating patients who experience side effects to methimazole (excluding agranulocytosis and hepatotoxicity).     

Patient Perspectives on the Extent of Surgery and Radioactive Iodine Treatment for Low-Risk Differentiated Thyroid Cancer

ObjectiveTo understand patient perspective regarding recommended changes in the 2015 American Thyroid Association (ATA) guidelines. Specifically, in regard to active surveillance (AS) of some small differentiated thyroid cancer (DTC), performance of less extensive surgery for low-risk DTC, and more selective administration of radioactive iodine (RAI).MethodsAn online survey was disseminated to thyroid cancer patient advocacy organizations and members of the ATA to distribute to the patients. Data were collected on demographic and treatment information, and patient experience with DTC. Patients were asked “what if” scenarios on core topics, including AS, extent of surgery, and indications for RAI.ResultsSurvey responses were analyzed from 1546 patients with DTC: 1478 (96%) had a total thyroidectomy, and 1167 (76%) underwent RAI. If there was no change in the overall cancer outcome, 606 (39%) of respondents would have considered lobectomy over total thyroidectomy, 536 (35%) would have opted for AS, and 638 (41%) would have chosen to forego RAI. Moreover, (774/1217) 64% of respondents wanted more time with their clinicians when making decisions about the extent of surgery. A total of 621/1167 of patients experienced significant side effects with RAI, and 351/1167 of patients felt that the risks of treatment were not well explained. 1237/1546 (80%) of patients felt that AS would not be overly burdensome, and quality of life was the main reason cited for choosing AS.ConclusionPatient perspective regarding choice in the management of low-risk DTC varies widely, and a large proportion of DTC patients would change aspects of their care if oncologic outcomes were equivalent.     

The Evaluation of Low- and High-Dose Steroid Treatments in Subacute Thyroiditis: A Retrospective Observational Study

ObjectiveThe optimal steroid regimen in the treatment of subacute thyroiditis (SAT) is controversial. This study aims to compare low- and high-dose steroid regimens in the treatment of SAT.MethodsA single-center, retrospective observational cohort study with up to 1 year of follow-up was conducted. A total of 44 patients in the 16-mg methylprednisolone (MPS) group and 47 patients in the 48-mg MPS group were enrolled. Clinical and laboratory findings from the time of diagnosis to 1-year of the follow-up were assessed. Treatment response, recurrence, and hypothyroidism (HPT) rates were evaluated.ResultsClinical symptoms, sedimentation rates, C-reactive protein, and thyroid hormone levels of the patients were similar in the 2 groups. Recovery was achieved in all patients at the end of the treatments; however, treatment duration needed to be extended for 6 (13.6%) and 1 (2.1%) of the patients in the 16-mg and 48-mg MPS groups, respectively. The 48-mg MPS group had a higher SAT recurrence rate than the 16-mg MPS group (P = .04). Logistic regression analysis suggested that a lower thyroid-stimulating hormone level at the end of the treatment was a predictor of recurrence (β = –0.544, P = .014, 95% CI: 0.376-0.895). While the transient HPT rate was 10 (21.3%) and 10 (22.7%) in the 48-mg and 16-mg MPS groups, respectively, a permanent HPT developed in 5 (10.6%) of patients in the 48-mg MPS and 3 (6.8%) in the 16-mg MPS group. The permanent and transient HPT rates were determined to be similar in the low- and high-dose groups (P > .05).ConclusionLow-dose steroid therapy may be sufficient to achieve a complete recovery and better outcomes in SAT.     

Gonadotropin Therapy Once a Week for Spermatogenesis in Hypogonadotropic Hypogonadism

ObjectiveHypogonadotropic hypogonadism (HH) can be caused by congenital HH (CHH), pituitary stalk interruption syndrome (PSIS), and pituitary injury (acquired HH). Gonadotropin therapy, typically administered every other day or twice a week, is commonly used to promote spermatogenesis. The aim of this retrospective study was to evaluate the efficacy of weekly gonadotropin therapy on spermatogenesis in patients with HH (n = 160).MethodsThe patients’ diagnoses include Kallmann syndrome (KS) (n = 61), normosmic CHH (nCHH) (n = 34), PSIS (n = 48), and acquired HH (n = 17). The rate of successful spermatogenesis and median time to achieve spermatogenesis among these 4 subgroups were compared as well as between a weekly group (n = 95) and a twice-a-week group (n = 223) of CHH patients.ResultsOnce-a-week gonadotropin therapy resulted in 74% (119/160) of HH patients achieving spermatogenesis with significantly increased testicular volume and total testosterone levels (P < .001). The median period of spermatogenesis was 13 (interquartile range[IQR] 11.4-14.6) months. Larger basal testicular volume (P = .0142) was an independent predictor for earlier sperm appearance. Six spontaneous pregnancies occurred. Compared with the twice-a-week regimen for spermatogenesis, the weekly injection group had a similar median time of sperm appearance (14 [IQR, 11.6-16.4] vs 15 [IQR, 13.5-16.5] months), success rate (78% [74/95] vs 64% [143/223]), sperm concentration (20.9 [IQR, 5.0-46.3] vs 11.7 [IQR, 2.1-24.4] million/mL), and progressive sperm motility (40.8 ± 27.3% vs 36.9% ± 20.2%).ConclusionWeekly gonadotropin therapy is effective in inducing spermatogenesis, similar to that of twice-a-week therapy. A larger basal testicular size was a favorable indicator for earlier spermatogenesis.
