Acromegaly increases depressive symptoms and reduces quality of life of cohabitants.

PURPOSE: To assess how living with patients with acromegaly affects people's psychology and quality of life (QoL). METHODS: Acromegaly patients and their cohabitants included in this study. Patients were administered Acromegaly Quality of Life Questionnaire (AcroQoL), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI). Cohabitants were administered quality of life questionnaire (SF-36), BAI, BDI, and Zarit Caregiver Burden Interview (ZBI). RESULTS: This study included 84 patients with acromegaly and 84 cohabitants. Sixty-nine patients (n = 84, 82.1%) had an acromegalic appearance. Cohabitants who were affected by the acromegalic appearance had higher BAI, BDI, and ZBI scores than those who were not affected (p < 0.001 for all). Cohabitants who were affected by the acromegalic appearance had a significantly lower SF-36 score (p = 0.015). The BAI (r=-0.535, p < 0.001), BDI (r=-0.592, p < 0.001), and ZBI (r=-0.465, p < 0.001) scores of the cohabitants showed a negative correlation with AcroQoL. SF-36 scores showed correlation with AcroQoL (r = 0.387, p < 0.001). CONCLUSION: The chronic process of acromegaly and the external appearance of patients with this disease can negatively affect both the patients and the people living with them. Physicians being aware of this effect and taking counteractive measures may contribute positively to the course of acromegaly.

Disordered eating behaviors in gender-affirmative treatment seeking transgender people.

This study aimed to explore disordered eating behaviors in gender-affirming treatment (GAT)-seeking transgender (TG) adults and cisgender people, in addition to analyzing the association between gender dysphoria intensity, body mass index, and disordered eating behaviors. Data were collected from 132 GAT-seeking TG people with gender dysphoria who had never received GAT (91 TG men, 41 TG women), and 153 cisgender (99 cisgender men, 54 cisgender women) participants from Turkey. The Utrecht Gender Dysphoria Scale was used to evaluate the intensity of gender dysphoria. Eating Disorder Examination Questionnaire and Questionnaire on Eating and Weight Patterns-5 were utilized to assess disordered eating. There was no difference between TG women and TG men in terms of ED psychopathology. The most prominent characteristic in all four groups was shape concern, which was significantly higher in TG men and TG women when compared to cisgender men and cisgender women. Binge eating was notably more frequent in TG men and TG women compared to cisgender men, with 11% of the TG men and 7.3% of the TG women meeting the criteria for possible binge eating disorder. Screening for disordered eating behaviors, particularly binge eating, may be recommended in routine care for TG people.

Does the Association of Hashimoto's Thyroiditis with Differentiated Thyroid Cancer Really Have a Protective Role?

The study is an investigation of aggressive tumor features, prognosis, and disease-specific mortality rates of differentiated thyroid cancer (DTC) in the presence of concomitant Hashimoto's Thyroiditis (HT). The data of patients with DTC followed in our tertiary care center between 2000-2022 were analyzed. Variables such as patient age, gender, preoperative serum autoantibody levels, tumor characteristics, and treatment modalities were obtained from medical records. The diagnosis of HT was based either on the presence of a positive result in the pathological examination and/or on antibody positivity. A total of 637 patients [mean±SD age, 44.9±13.5 years; 485 women [76.1%)] were included in the analysis. The overall prevalence of coexistent HT was 22.9% (n=146). The disease-specific mortality associated with DTC was 2.9%. DTC patients with HT compared to those without; have more positive lymphovascular invasion (p<0.001), and lymph node metastases (p<0.001). According to the Kaplan-Meier curves, disease-specific survival rates among DTC patients without HT were significantly higher than patients with HT (log-rank p=0.002). The disease-specific mortality rate was 4.79% in DTC patients with HT, it was 1.43% in those without HT. Hashimoto thyroiditis was not associated with a 10-year recurrence-free survival (p=0.059). Differentiated thyroid cancers with concomitant HT are associated with some aggressive tumor features (such as lymphovascular invasion and nodal metastasis) and lower survival. In staging systems based on tumor risk factors, it may be useful to evaluate the presence of concomitant HT as a prognostic factor.

Altered thalamic volume in patients with mild autonomous cortisol secretion: a structural brain MRI study.

PURPOSE: To compare thalamic volume and cognitive functions of patients with mild autonomous cortisol secretion (MACS) with control subjects and patients with overt Cushing's syndrome (CS). METHODS: In this cross-sectional study, volumes of regions of interest were assessed using 3 T magnetic resonance imaging and a voxel-based morphometry approach in 23 patients with MACS, 21 patients with active CS, 27 patients with CS in remission, and 21 control subjects. Cognitive functions were assessed using validated questionnaires. RESULTS: Patients with MACS had smaller left thalamic (F = 3.8, p = 0.023), left posterior thalamic (F = 4.9, p = 0.01), left medial thalamic (F = 4.7, p = 0.028), and right lateral thalamic (F = 4.1, p = 0.025) volumes than control subjects. Patients with active CS also had smaller left thalamic (F = 3.8, p = 0.044), left posterior thalamic (F = 4.9, p = 0.007), left medial thalamic (F = 4.7, p = 0.006), and right lateral thalamic (F = 4.1, p = 0.042) volumes compared to controls. Patients with CS in remission had smaller left medial (F = 4.7, p = 0.030) and right lateral thalamic (F = 4.1, p = 0.028) volumes than controls. Neuropsychological tests showed no difference between the groups. CONCLUSION: MACS may decrease thalamic volume.

Nociceptive flexion reflex in small fibers neuropathy and pain assessments†.

BACKGROUND: The nociceptive flexion reflex (NFR) is a polysynaptic and multisegmental spinal reflex that develops in response to a noxious stimulus and is characterized by the withdrawal of the affected body part. The NFR possesses two excitatory components: early RII and late RIII. Late RIII is derived from high-threshold cutaneous afferent A-delta fibers, which are prone to injury early in the course of diabetes mellitus (DM) and may lead to neuropathic pain. We investigated NFR in patients with DM with different types of polyneuropathies to analyze the role of NFR in small fiber neuropathy (SFN). METHODS: We included 37 patients with DM and 20 healthy participants of similar age and sex. We performed the Composite Autonomic Neuropathy Scale-31, modified Toronto Neuropathy Scale, and routine nerve conduction studies. We grouped the patients into large fiber neuropathy (LFN), SFN, and no overt neurological symptom/sign groups. In all participants, NFR was recorded on anterior tibial (AT) and biceps femoris (BF) muscles after train stimuli on the sole of the foot, and NFR-RIII findings were compared. RESULTS: We identified 11 patients with LFN, 15 with SFN, and 11 with no overt neurological symptoms or signs. The RIII response on the AT was absent in 22 (60%) patients with DM and 8 (40%) healthy participants. The RIII response on the BF was absent in 31 (73.8%) patients and 7 (35%) healthy participants (P = .001). In DM, the latency of RIII was prolonged, and the magnitude was reduced. Abnormal findings were seen in all subgroups; however, they were more prominent in patients with LFN compared to other groups. CONCLUSIONS: The NFR-RIII was abnormal in patients with DM even before the emergence of the neuropathic symptoms. The pattern of involvement before neuropathic symptoms was possibly related to an earlier loss of A-delta fibers.

Changing presentation of acromegaly in half a century: a single-center experience.

OBJECTIVE: Investigate the changes in the characteristics of presentation, in patients with acromegaly over a period of approximately half a century. METHODS: The medical records of patients diagnosed with acromegaly between 1980 and 2023 were retrospectively reviewed. The collected data were examined to assess any changes observed over the years and a comparison was made between the characteristics of patients diagnosed in the last decade and those diagnosed in previous years. RESULTS: A total of 570 patients were included in the study, 210 (37%) patients were diagnosed in the last decade. Patients diagnosed before 2014 had longer symptom duration before diagnosis, advanced age, larger pituitary adenomas, higher incidence of cavernous sinus invasion, and higher GH and IGF-1 levels than those diagnosed last decade (p < 0.05, for all). Furthermore, the patients diagnosed before 2014 had a lower rate of surgical remission (p < 0.001), and a higher prevalence of comorbidities such as diabetes, hypertension, colon polyps, and thyroid cancer at the time of diagnosis (p < 0.05, for all). CONCLUSION: There may be a trend for earlier detection of patients with acromegaly.

Risk of impulse control disorders in patients with Cushing's disease: do not blame cabergoline but do not give up caution.

PURPOSE: To asses risk of new-onset impulse control disorders (ICDs) in patients with Cushing's disease (CD) who initiated cabergoline (CBG) and to determine frequency of ICDs in CBG-treated patients with CD. METHODS: This naturalistic observational study had prospective and cross-sectional arms which included patients at five referral centers based in Istanbul. Patients who were scheduled for CBG were assigned to prospective arm. These patients underwent neuropsychological tests (Barratt Impulsiveness Scale, Minnesota Impulsive Disorders Interview, Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale, Go/No-Go Task, Iowa Gambling Task, and Short Penn Continuous Performance Test) for assessment of impulsivity and psychiatric evaluations at baseline, 3, 6, and 12 months of CBG treatment. Impulsivity and new-onset ICDs were prospectively assessed. Patients with CD with current CBG treatment for ≥ 3 months and matched CBG-naïve patients with CD were included in cross-sectional arm. These patients underwent the same neuropsychological and psychiatric assessments. The impulsivity and frequency of ICDs were compared between CBG-treated and CBG-naïve patients with CD. RESULTS: The follow-up duration of prospective cohort (n = 14) was 7.3 ± 2.3 months. One patient developed major depressive episode and another patient developed compulsive gambling after CBG. We observed no significant changes in impulsivity scores during follow-up. In cross-sectional arm, CBG-treated (n = 34) and CBG-naïve patients (n = 34) were similar in impulsivity scores and frequency of ICDs [3 patients (8.8%) vs. 2 patients (5.9%) respectively, p = 1.0]. CONCLUSION: CBG-treated patients with CD appeared to have a low risk of ICDs, suggesting that CBG still holds promise as a safe agent in CD.

Investigation of Obesity-Related HAdV-36 in NAFLD Patients: a Case-Control Study.

BACKGROUND: HAdV-36 leads to adipocyte proliferation of adipose tissue through E4orf1 gene, leading to the development of obesity and related diseases. We aimed to investigate the presence and any association of HAdV-36 in non-alcoholic fatty liver disease (NAFLD) patients Methods: The patient group was composed of 116 patients; 30 obese patients with NAFLD (BMI > 30 kg/m2), 30 patients with Diabetes Mellitus (DM)+NAFLD (BMI > 30 kg/m2), 16 patients with NAFLD (BMI < 30 kg/m2), and operated obese group with NAFLD (BMI > 30 kg/m2). The control group comprised 81 non-obese healthy adults. Liver adipose tissue samples were obtained in 30 operated NAFLD patients. HAdV-36-DNA, HAdV-36 neutralizing antibodies, serum lipid, and adipokine levels were analyzed. RESULTS: HAdV-36 neutralizing antibodies (HAdV-36 Ab-positive) were detected in 10/116 and 2/81 participants in the study and control groups, respectively; the difference was statistically significant (p < 0.005). LDL, total cholesterol but not adipokine levels were found to be significantly higher in HadV-36 Ab-positive patients (p < 0.05). While HAdV-36 was identified as a risk factor with OR = 4.11 in univariate analyses, there was no significant difference in binary logistic regression analysis. HAdV-36-DNA was detected in the adipose tissue samples of two patients. CONCLUSIONS: We suggest that the presence of HAdV-36 may lead to the development of obesity with the increase in adipose tissue, and diseases such as hyperlipidemia, NAFLD, DM, and metabolic syndrome may develop on the basis of chronic inflammation caused by obesity. Thus, HAdV-36 may be a plausible risk factor for the development of NAFLD.

Assessment of Neuroendocrine Changes and Hypothalamo-Pituitary Autoimmunity in Patients with COVID-19.

SARS-CoV-2 may affect the hypothalamic-pituitary axis and pituitary dysfunction may occur. Therefore, we investigated neuroendocrine changes, in particular, secondary adrenal insufficiency, using a dynamic test and the role of autoimmunity in pituitary dysfunction in patients with COVID-19. The single-center, prospective, case-control study included patients with polymerase chain reaction (PCR)-confirmed COVID-19 and healthy controls. Basal hormone levels were measured, and the adrenocorticotropic hormone (ACTH) stimulation test was performed. Antipituitary (APA) and antihypothalamic antibodies (AHA) were also determined. We examined a total of 49 patients with COVID-19 and 28 healthy controls. The frequency of adrenal insufficiency in patients with COVID-19 was found as 8.2%. Patients with COVID-19 had lower free T3, IGF-1, and total testosterone levels, and higher cortisol and prolactin levels when compared with controls. We also demonstrated the presence of APA in three and AHA in one of four patients with adrenal insufficiency. In conclusion, COVID-19 may result in adrenal insufficiency, thus routine screening of adrenal functions in these patients is needed. Endocrine disturbances in COVID-19 are similar to those seen in acute stressful conditions or infections. Pituitary or hypothalamic autoimmunity may play a role in neuroendocrine abnormalities in COVID-19.

Fertility Desire and Motivation Among Individuals with Gender Dysphoria: A Comparative Study.

Despite receiving Gender-Affirming Hormone Therapy or Gender-Affirming Surgery, which may adversely impact their fertility, people with Gender Dysphoria (GD) may desire to form families. In this study, we aimed to quantitatively display fertility desire from the perspective of these individuals, despite all the legal challenges they face. The single center, cross-sectional comparative study included individuals with GD and cisgender volunteers. A Sociodemographic Data Form, the Fertility Desire Data Form, the Childbearing Motivations Scale and the Fertility Desire Scale were used. Of the 414 participants, 171 were individuals with GD (110 FtM; 61 MtF) and 243 were cisgender volunteers (142 cis-males; 101 cis-females). While 22% of the people with GD stated that they had regrets about not undergoing fertility preservation, 16% stated that they would like this process if it were legal. People with GD, particularly MtF, want to have children more than cisgenders. Moreover, people with MtF exhibited less negative motivations toward becoming parents, despite having reservations regarding the socioeconomic aspect of parenthood. Our findings indicate that fertility desire in people with GD is not less in comparison to cisgender people. Healthcare professionals should not forget to offer fertility preservation options as part of clinical practice before Gender-Affirming Therapy.

TransCOVID: Does Gender-Affirming Hormone Therapy Play a Role in Contracting COVID-19?

Based on the possible effects of androgens on the course of COVID-19, it can be posited that Gender-Affirming Hormone Therapy (GAHT) may affect the course of the disease in people with GD. We aimed to investigate the relationship between GAHT and contracting COVID-19, as well as the severity of the disease in individuals with Gender Dysphoria (GD). The single center, cross-sectional, web-based survey was completed by people with GD who received GAHT. The questionnaire contained three parts: a sociodemographic data form; a GAHT data form; a COVID-19-related data form. Of the 238 participants, 179 were individuals with female-to-male (FtM) and 59 male-to-female (MtF) GD. We detected that the risk of contracting COVID-19 increased 3.46 times in people with FtM GD, who had received testosterone therapy, in comparison to people with MtF GD, who received estrogen and anti-androgen therapy. Additionally, people with FtM GD who contracted COVID-19 had received longer testosterone therapy when compared to those who did not contract COVID-19. Our findings indicate that individuals with FtM GD who receive testosterone treatment within the scope of GAHT are at higher risk of contracting COVID-19 and that the clinicians who follow-up on GAHT should be more careful about this issue.

Problem-solving therapy can reduce psychological distress in patients with Cushing's disease: a randomized controlled trial.

OBJECTIVE: To evaluate the effects of online group problem-solving therapy (PST) for reducing negative problem orientation (NPO), psychological distress, and increasing quality of life in patients with Cushing's disease (CD). METHODS: In this randomized trial, we allocated 55 eligible patients to either PST (n = 28) or treatment as usual (TAU) (n = 27) groups. The analyses primarily relied on intent-to-treat (ITT) principle and were repeated with intervention completers (per-protocol analyses). Social problem-solving inventory-revised short form, Beck Depression Inventory (BDI), General Health Questionnaire-12 (GHQ-12), Perceived Stress Scale (PSS), The Satisfaction with Life Scale, and Cushing's Quality of Life scale were used. Pre-test, post-test, and follow-up measures were obtained. Linear mixed models were used to compare PST and treatment as usual (TAU) groups across time. RESULTS: Of the total 55 patients with CD, the mean age was 46 ± 12 years, 49 patients (89%) were female, and 41 patients (74.5%) were in remission. The patients within the PST and TAU groups were similar in terms of age, sex, and disease activity. ITT analyses showed a greater reduction of NPO scores in patients who received PST as compared to patients who received usual care (df = 45.9, p = 0.029, Cohen's d = 0.47). The decrease in NPO was sustained at follow-up (mean difference: - 2.2, p = 0.007). Results of the ITT analyses revealed no superior benefits of the intervention for psychological distress. However, per-protocol analyses demonstrated that PST provided a greater decrease in BDI, PSS, and GHQ-12 scores. CONCLUSION: PST may decrease NPO and improve the psychological well-being of patients with CD.

Machine learning as a clinical decision support tool for patients with acromegaly.

OBJECTIVE: To develop machine learning (ML) models that predict postoperative remission, remission at last visit, and resistance to somatostatin receptor ligands (SRL) in patients with acromegaly and to determine the clinical features associated with the prognosis. METHODS: We studied outcomes using the area under the receiver operating characteristics (AUROC) values, which were reported as the performance metric. To determine the importance of each feature and easy interpretation, Shapley Additive explanations (SHAP) values, which help explain the outputs of ML models, are used. RESULTS: One-hundred fifty-two patients with acromegaly were included in the final analysis. The mean AUROC values resulting from 100 independent replications were 0.728 for postoperative 3 months remission status classification, 0.879 for remission at last visit classification, and 0.753 for SRL resistance status classification. Extreme gradient boosting model demonstrated that preoperative growth hormone (GH) level, age at operation, and preoperative tumor size were the most important predictors for early remission; resistance to SRL and preoperative tumor size represented the most important predictors of remission at last visit, and postoperative 3-month insulin-like growth factor 1 (IGF1) and GH levels (random and nadir) together with the sparsely granulated somatotroph adenoma subtype served as the most important predictors of SRL resistance. CONCLUSIONS: ML models may serve as valuable tools in the prediction of remission and SRL resistance.

Psychosocial effects and clinic reflections of the COVID-19 outbreak in patients with acromegaly and Cushing's disease.

PURPOSE: Patients with acromegaly and Cushing's disease (CD) may experience significant problems related to the COVID-19 outbreak. We aimed to investigate the psychosocial effects of the pandemic and reveal the follow-up characteristics. METHODS: The single center, cross-sectional, web-based survey study included patients with acromegaly and CD, PCR-confirmed COVID-19 patients and healthy volunteers without known any chronic disease. The semi-structured sociodemographic data form, The State-Trait Anxiety Inventory (STAI) and Impact of Event Scale-Revised (IES-R) were used. RESULTS: We examined 583 people (217 acromegaly, 127 CD, 102 PCR-confirmed COVID-19 patients and 137 healthy controls). The frequency of abnormal state anxiety and post-traumatic stress disorder (PTSD) were similar in patients with acromegaly and CD and healthy controls, and higher in PCR-confirmed COVID-19 patients than in these three groups (p < 0.001 for both). The frequency of abnormal trait anxiety was higher in patients with acromegaly and PCR-confirmed COVID-19 compared to patients with CD and healthy controls (p = 0.027, p < 0.001, respectively). There were no significant differences between the acromegaly and CD groups in terms of follow-up characteristics and perception of the severity of the COVID-19 outbreak (p > 0.05 for all). But, the treatment discontinuation rate was higher in patients with acromegaly than CD (p = 0.012). CONCLUSIONS: Our findings indicate that acromegaly and CD patients are psychologically less affected than PCR-confirmed COVID-19 patients and exhibit similar findings the general population. The clinicians should consider the psychosocial effects, as well as focus on the regular follow-up and medical treatments of these patients during the outbreak.

The effect of somatostatin analogs and acromegaly on the upper gastrointestinal system.

PURPOSE: To evaluate the effects of somatostatin analogs and disease activity status on the upper gastrointestinal system in patients with acromegaly. METHODS: One hundred eighty-one patients with acromegaly were retrospectively assessed. The demographic, biochemical, pathologic, and radiologic data of the patients were evaluated. The upper gastrointestinal endoscopies and endoscopic biopsies were investigated. We divided patients into four groups according to the use of somatostatin analogs, and into two groups according to disease activity. We compared the data of patients between groups A, B, C, and D, and controlled/uncontrolled groups separately. RESULTS: Before and in the peri-endoscopic period, 67 and 27 patients were being treated with octreotide long-acting release (LAR) (group A) and lanreotide autogel (group B), respectively. Twenty-one patients used somatostatin analogs, but they were stopped for various reasons before upper gastrointestinal endoscopy (group C), and 66 patients did not use a somatostatin analog (group D). In the peri-endoscopic period, 103 (60%) patients were responsive to medical and/or surgical treatment and 67 (40%) patients were non-responsive. The rate of gastritis was higher in group A than in groups B and D. The incidence of duodenitis and gastric ulcer was much higher in group D. The rate of gastritis was higher in the controlled group compared to the uncontrolled group. CONCLUSION: The study showed that octreotide LAR treatment could be a risk factor in addition to known factors for the development of gastritis in patients with acromegaly.

Treat Obesity to Treat Type 2 Diabetes Mellitus.

Obesity, a multifactorial, relapsing chronic disease, serves as a gateway to a spectrum of metabolic, cardiovascular, mechanical and mental health problems. Over the last few decades, the global prevalence of obesity has surged nearly threefold, mirroring the escalating rates of type 2 diabetes mellitus (T2DM). This parallel trajectory strongly suggests a cause-and-effect relationship between obesity and T2DM. Extensive research indicates that even modest weight gain elevates the risk of T2DM, favoring the notion of obesity being a root cause. This perspective finds robust support in numerous studies demonstrating the preventive effects of obesity management on the onset of T2DM. Beyond prevention, obesity management has been shown to enhance remission in individuals with T2DM and to decrease microvascular complications, cardiovascular risk factors, renal failure and heart failure. This evidence underpins the urgent need for global initiatives aimed at addressing obesity management as a key strategy in the prevention and management of T2DM and its complications.

The Effect of Metformin Treatment on Disease Control in Patients with Acromegaly.

BACKGROUND: The increase in portal insulin levels has been shown to upregulate growth hormone receptor expression in the liver, leading to increased insulin-like growth hormone- 1 levels. Metformin inhibits hepatic gluconeogenesis and reduces fasting insulin. OBJECTIVE: We evaluated the effect of metformin treatment in patients with acromegaly on growth hormone, insulin-like growth hormone-1, and pituitary adenoma size. METHODS: Patients who were followed up with the diagnosis of acromegaly in Istanbul University- Cerrahpasa, Cerrahpasa Medical Faculty were evaluated. The patients were divided into three groups after pituitary adenectomy as those who received somatostatin receptor ligand and metformin treatment (group A), somatostatin receptor ligand treatment only (group B), and those who received metformin treatment only (group C). Groups A and B were compared with each other, and patients in group C were compared among themselves. RESULTS: While the median insulin-like growth factor-1 level decreased to 170 ng/ml in Group A after the treatment, the median insulin-like growth factor-1 level decreased to 229 ng/ml in Group B, and a statistically significant difference was found between the two groups (p =0.020). There was no significant difference in post-treatment growth hormone levels and residual adenoma sizes between groups A and B (p >0.005). In group C, there was no significant difference in growth hormone values pre-and post-metformin treatment (p =0.078); however, the median insulin-like growth factor-1 level decreased from 205 ng/ml to 168 ng/ml during metformin treatment and was found to be statistically significant (p =0.027). CONCLUSION: Due to the effect of metformin treatment on insulin-like growth factor-1 values in patients with acromegaly, it can be used in disease control, as well as diabetes treatment.

The Association Between Oxidative Stress and Sperm Parameters in Patients with Acromegaly.

OBJECTIVE: Spermatozoa are susceptible to oxidative radicals when antioxidant defenses are inadequate. The extent to which oxidative radicals contribute to sperm damage in patients with acromegaly remains unclear. This study aimed to investigate and elucidate this relationship. METHODS: The overall status of oxidants and antioxidants in both seminal plasma and serum of patients with acromegaly compared to a control group of healthy individuals was investigated. In addition, sperm parameters, including important measures such as growth hormone and insulin-like growth factor-1 concentrations. RESULTS: Twenty-two patients with acromegaly with controlled disease and 14 healthy controls were included. The total oxidant status was significantly higher in the semen samples of the patients with acromegaly. A negative correlation was found between sperm total oxidant status and total sperm count and sperm concentration. Similarly, a negative correlation was found between the total sperm count and the sperm oxidative stress index. In individuals diagnosed with acromegaly, there was a statistically significant increase in sperm growth hormone levels. Conversely, the level of insulin-like growth factor 1 was significantly increased in the sperm of the control group, which consisted of healthy individuals. The correlation analysis revealed a significant relationship between venous total oxidant status and growth hormone levels in semen. CONCLUSION: The elevated levels of reactive oxygen radicals in individuals with acromegaly suggest a possible link between oxidative stress and its effects on semen quality.

Is There A Connection Between Primary Hypophysitis and Celiac Disease?

AIM: To investigate the autoimmune and genetic relationship between primary hypophysitis (PH) and celiac disease (CD). METHODS: The study was retrospective and patients with PH followed in our clinic between 2007 and 2022 were evaluated. Clinical, endocrinologic, pathologic, and radiologic findings and treatment modalities were assessed. Patients diagnosed with CD in the Gastroenterology outpatient clinic in 2020-2022 were included in the study as a control group. Information such as sociodemographic data, year of diagnosis, human leukocyte antigen (HLA) DQ2/8 information, CD-specific antibody levels, pathologic results of duodenal biopsy, treatment received, follow-up status, additional diseases, hormone use, and surgical history was obtained from patient records at PH.In patients diagnosed with PH, a duodenal biopsy was obtained, and the tissue was examined for CD by experienced pathologists. Anti-pituitary antibody (APA) and anti-arginine-vasopressin (AAVP) antibody levels of individuals with PH and CD were measured. RESULTS: The study included 19 patients with lymphocytic hypophysitis, 30 celiac patients, and 30 healthy controls. When patients diagnosed with lymphocytic hypophysitis were examined by duodenal biopsy, no evidence of CD was found in the pathologic findings. The detection rate of HLA-DQ2/8 was 80% in celiac patients and 42% in PH (p=0.044). (APA and AAVP antibodies associated with PH were tested in two separate groups of patients and in the control group. APA and anti-arginine vasopressin (AAVP) levels in PH, CD and healthy controls, respectively M [IQR]: 542 [178-607];164 [125-243]; 82 [74-107] ng/dL (p=0.001), 174 [52-218]; 60 [47-82]; 59 [48-76] ng/dL (p=0.008) were detected. The presence of an HLA-DQ2/8 haplotype correlates with posterior hypophysitis and panhypophysitis (r=0.598, p=0.04 and r=0.657, p=0.02, respectively). CONCLUSION: Although patients with PH were found to have significant levels of HLA-DQ2/8, no CD was found in the tissue. Higher levels of pituitary antibodies were detected in celiac patients compared with healthy controls, but no hypophysitis clinic was observed at follow-up. Although these findings suggest that the two diseases may share a common genetic and autoimmune basis, the development of the disease may be partially explained by exposure to environmental factors.

Serum Lipoprotein(a) Is Not Associated with Graves' Ophthalmopathy.

Aim: To investigate the relationship of serum lipoprotein(a) [Lp(a)] and other serum lipids with presence of Graves' ophthalmopathy (GO). Methods: A total of 99 consecutive patients diagnosed with Graves' disease (GD), aged 18-65 years, who had not received prior treatment for GO, thyroid surgery, or radioactive iodine therapy, were recruited between June 2020 and July 2022. In addition, 56 healthy controls (HCs) were included as the control group. All patients underwent an ophthalmological examination, and were classified based on the presence of GO into the GO group (n = 45) and no GO group (n = 54). Fasting blood samples were collected from all participants to analyze serum lipid parameters, including Lp(a), total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides. Results: The median serum levels of Lp(a) were 5.7 [4.3-9.2] in the GO group, 6.7 [3.7-9.9] in the no GO group, and 4.7 [3-7.6] in the HC group. The intergroup comparisons of serum Lp(a) levels showed no significant result. The serum levels of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides were also similar between the groups (P > 0.05 for all). However, when analyzing only euthyroid GD patients and the control group, the serum LDL cholesterol levels were found to be significantly higher in the euthyroid GO group [median: 132 interquartile range (IQR) (110-148) mg/dL] than in the HCs [median: 96 IQR (94-118) mg/dL] (P = 0.002). Conclusion: The findings of our study did not support the association between serum Lp(a) levels and GO.
