Normative data for insulin-like growth factor-1 (IGF-1) in healthy children and adolescents from India.

BACKGROUND: Serum IGF-1 is an important biochemical tool to diagnose and monitor GH-related disorders. However, ethnic-specific Indian data following consensus criteria for the establishment of normative data, are not available. Our objective was to generate chronological age (CA)-, bone age (BA)- and Tanner stage-specific normative data for IGF-1 in healthy Indian children and adolescents. METHODS: A cross-sectional epidemiological study was conducted in schools and the community, which enrolled apparently healthy children and adolescents with robust exclusion criteria. The outcome measure was serum IGF-1 assessed using an electro-chemiluminescence immunoassay (ECLIA). The 2.5th, 5th, 10th, 25th, 50th (median), 75th, 90th, 95th, and 97.5th centiles for IGF-1 were estimated using generalized additive models. RESULTS: We recruited 2226 apparently healthy participants and following exclusion, 1948 (1006 boys, 942 girls) were included in the final analysis. Girls had median IGF-1 peak at CA of 13 years (321.7 ng/mL), BA of 14 years (350.2 ng/mL) and Tanner stage IV (345 ng/mL), while boys had median IGF-1 peak at CA of 15 years (318.9 ng/mL) BA of 15 years (340.6 ng/mL) and Tanner stage III (304.8 ng/mL). Girls had earlier rise, peak and higher IGF-1 values. The reference interval (2.5th-97.5th percentile) was broader during peri-pubertal ages, indicating a higher physiological variability. CONCLUSION: This study provides ethnicity-specific normative data on serum IGF-1 and will improve the diagnostic utility of IGF-1 in the evaluation and management of growth disorders in Indian children and adolescents.

Comprehensive safety profile of dipeptidyl peptidase-4 inhibitors: a post-marketing study based on FAERS database using signal detection algorithms.

BACKGROUND: Dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors) have acquired a foothold in managing type 2 diabetes mellitus, but few concerns have arisen regarding their overall safety profile. The aim of this study is to assess the potential risk of DPP-4 inhibitors by analyzing data from the FDA Adverse Event Reporting System (FAERS) database. RESEARCH DESIGN AND METHODS: This is a retrospective study which explored the FAERS database till March 2023 for the collection of safety reports. The disproportionality analysis was performed using signal detection algorithms (SDAs) incorporating frequentist-based data mining approach such as relative reporting ratio (RRR), reporting odds ratio (ROR) and proportional reporting ratio (PRR) with 95% confidence interval (CI). RESULTS: A total of 14,573 adverse event reports were reported in the FAERS public dashboard associated with all the included DPP-4 inhibitors. The computed PRR, ROR, and RRR indicated positive signals for DPP-4 inhibitors with cardiac failure, pancreatitis, pemphigoid, hypoglycemia, acute kidney injury and lactic acidosis. Saxagliptin showed a higher signal score for cardiac failure, while sitagliptin was more associated with pancreatitis. Moreover, alogliptin exhibited an elevated signal score associated with pancreatic carcinoma. CONCLUSION: Several significant disproportionality signals were observed with DPP-4 inhibitors. However, clinicians have to consider the comorbidities and concomitant drugs while prescribing these drugs.

Impact of short-term application of continuous glucose monitoring system(CGMS) on long-term glycemic profile in adolescents and adults with type 1 diabetes mellitus: An open-label randomized control cross over study.

AIMS: The use of Continuous Glucose Monitoring System (CGMS) improves glycemic parameters in Type 1 Diabetes Mellitus (T1D), but the cost is prohibitive. Here, we investigated the effect of short-term application of real-time and intermittently-scanned CGMS (rt and is-CGMS) in T1D individuals on change in HbA1c at the end of 3 months. METHODS: T1D individuals were randomized into three groups in a ratio of 1:1:2 - Group A (rt-CGMS for 2 weeks initially, followed by is-CGMS for 2 weeks at 3 months), Group B (is-CGMS for 2 weeks initially followed by rt-CGMS for 2 weeks at 3 months) and Group C (only self-monitoring of blood glucose), respectively. HbA1c at baseline, 3, and 6 months were compared. RESULTS: Out of a total 68 T1D patients, HbA1c decreased significantly in groups A and B at 6 months compared to the baseline, but not in group C. HbA1c was significantly lower in Group A compared to Group C at 3 and 6 months. Fructosamine levels significantly decreased in Group B before and after cross-over. Glycemic variability indices improved significantly after cross-over from is-CGMS to rt-CGMS. CONCLUSION: Intermittent application of CGMS for 2 weeks improves short- and long-term blood glucose control in T1D.

Bone mineral density, turnover, and microarchitecture assessed by second-generation high-resolution peripheral quantitative computed tomography in patients with Sheehan's syndrome.

Sheehan's syndrome (SS) is a rare but well-characterized cause of hypopituitarism. Data on skeletal health is limited and on microarchitecture is lacking in SS patients. PURPOSE: We aimed to explore skeletal health in SS with bone mineral density (BMD), turnover, and microarchitecture. METHODS: Thirty-five patients with SS on stable replacement therapy for respective hormone deficiencies and 35 age- and BMI-matched controls were recruited. Hormonal profile and bone turnover markers (BTMs) were measured using electrochemiluminescence assay. Areal BMD and trabecular bone score were evaluated using DXA. Bone microarchitecture was assessed using a second-generation high-resolution peripheral quantitative computed tomography. RESULTS: The mean age of the patients was 45.5 ± 9.3 years with a lag of 8.3 ± 7.2 years prior to diagnosis. Patients were on glucocorticoid (94%), levothyroxine (94%), and estrogen-progestin replacement (58%). None had received prior growth hormone (GH) replacement. BTMs (P1NP and CTX) were not significantly different between patients and controls. Osteoporosis (26% vs. 16%, p = 0.01) and osteopenia (52% vs. 39%, p = 0.007) at the lumbar spine and femoral neck (osteoporosis, 23% vs. 10%, p = 0.001; osteopenia, 58% vs. 29%, p = 0.001) were present in greater proportion in SS patients than matched controls. Bone microarchitecture analysis revealed significantly lower cortical volumetric BMD (vBMD) (p = 0.02) at the tibia, with relative preservation of the other parameters. CONCLUSION: Low areal BMD (aBMD) is highly prevalent in SS as compared to age- and BMI-matched controls. However, there were no significant differences in bone microarchitectural measurements, except for tibial cortical vBMD, which was lower in adequately treated SS patients.

Trends estimation of obesity prevalence among South Asian young population: a systematic review and meta-analysis.

The premise for effective prevention and treatment of obesity is the availability of accurate prevalence figures. However, the prevalence of pediatric obesity and overweight in South Asian countries has seldom been analyzed. This article provides a comprehensive review and meta-analysis of studies on overweight and obesity to provide a more precise prevalence estimate. The study protocol was registered on PROSPERO (CRD42022320625). PubMed and Embase databases were comprehensively searched from inception till September 2023. The random-effects model was utilized to derive the pooled prevalence of obesity and overweight. Subgroup meta-analysis was used to assess variations in prevalence estimates across subgroups. A meta-regression analysis was also performed to assess the trend of overweight and obesity over the years. 152 studies were included with 489,525 participants. The pooled prevalence was 12.4 (95% CI 11.1-13.6) for overweight, 6.6% (95% CI 5.6-7.8) for obesity, and 19.3% (95% CI 17.1-21.7) for obesity and overweight. In subgroup analysis, Bangladesh reported a higher prevalence for both obesity (8.9%; 95% CI 4.9-13.9) and overweight (13.6%; 95% CI 9.2-18.8). Meta-regression analysis found a significant association between obesity prevalence and the publication year (ß = 0.004; p = 0.03; R2 = 2.74%). The results of this study indicate a relatively higher prevalence of childhood obesity in South Asia, emphasizing the necessity for large-scale awareness efforts and context-specific preventative methods.

Pituitary Dysfunction in Idiopathic Intracranial Hypertension: An Analysis of 80 Patients.

BACKGROUND: Empty sella is a commonly described imaging entity in patients with idiopathic intracranial hypertension (IIH). Though menstrual and hormonal disturbances have been associated with IIH, available literature lacks systematic analysis of pituitary hormonal disturbances in IIH. More so, the contribution of empty sella in causing pituitary hormonal abnormalities in patients of IIH has not been described. We carried out this study to systematically assess the pituitary hormonal abnormalities in patients with IIH and its relation to empty sella. METHODS: Eighty treatment naïve patients of IIH were recruited as per a predefined criterion. Magnetic resonance imaging (MRI) brain with detailed sella imaging and pituitary hormonal profile were done in all patients. RESULTS: Partial empty sella was seen in 55 patients (68.8%). Hormonal abnormalities were detected in 30 patients (37.5%), reduced cortisol levels in 20%, raised prolactin levels in 13.8%, low thyroid-stimulating hormone (TSH) levels in 3.8%, hypogonadism in 1.25%, and elevated levels of gonadotropins were found in 6.25% of participants. Hormonal disturbances were independent and were not associated with the presence of empty sella (p = 0.493). CONCLUSION: Hormonal abnormalities were observed in 37.5% patients with IIH. These abnormalities did not correlate with the presence or absence of empty sella. Pituitary dysfunction appears to be subclinical in IIH and responds to intracranial pressure reduction, not requiring specific hormonal therapies.

Transcription Factor Immunohistochemistry in the Classification of Pituitary Neuroendocrine Tumor/Adenoma: Proposal in a Limited-Resource Setting.

CONTEXT.­: Pituitary neuroendocrine tumors/adenomas are common intracranial tumors that require accurate subtyping because each tumor differs in its biologic behavior and response to treatment. Pituitary-specific transcription factors allow for improved lineage identification and diagnosis of newly introduced variants. OBJECTIVE.­: To assess the usefulness of transcription factors and design a limited panel of immunostains for classification of pituitary neuroendocrine tumors/adenoma. DESIGN.­: A total of 356 tumors were classified as per expression of pituitary hormones and transcription factors T-box family member TBX19 (TPIT), pituitary-specific POU-class homeodomain (PIT1), and steroidogenic factor-1 (SF-1). The resultant classification was correlated with patients' clinical and biochemical features. The performance and relevance of individual immunostains were analyzed. RESULTS.­: Reclassification of 34.8% (124 of 356) of pituitary neuroendocrine tumors/adenoma was done after application of transcription factors. The highest agreement with final diagnosis was seen using a combination of hormone and transcription factors. SF-1 had higher sensitivity, specificity, and predictive value compared with follicle-stimulating hormone and luteinizing hormone. On the other hand, TPIT and PIT1 had similar performance and Allred scores compared with their respective hormones. CONCLUSIONS.­: SF-1 and PIT1 should be included in the routine panel for guiding the classification. PIT1 positivity needs to be followed by hormone immunohistochemistry, especially in nonfunctional cases. TPIT and adrenocorticotropin can be used interchangeably as per availability of the lab.

Comparative study of diabetic ketoacidosis in the elderly and non-elderly patients: A nine-year experience from an academic hospital in North India.

BACKGROUND AND AIMS: Despite an increasing prevalence of the aged population with diabetes in low-middle-income countries, there is limited literature on geriatric hyperglycemic emergencies. The present study aimed to compare the spectrum and outcomes of diabetic ketoacidosis (DKA) between elderly and non-elderly adult patients in India. METHODS: Seventy-seven elderly patients (≥60 years) were compared to 477 non-elderly patients (13-59 years) with DKA admitted to the medical emergency, Postgraduate Institute of Medical Education and Research, Chandigarh, India, between January 2014 and December 2022. Clinical features, laboratory parameters, precipitating factors, and in-hospital outcomes were reviewed. RESULTS: Elderly patients less commonly had vomiting and abdominal pain than non-elderly patients (31.3 % vs. 66.2 %, 27.3 % vs. 60.1 %, respectively) and typically presented with dyspnea (48.5 %), altered mental status (47.8 %), and fever (46.3 %). Ketonemia and metabolic acidosis were significantly more marked in non-elderly patients, whereas elderly patients frequently had anemia, hypoalbuminemia, and renal dysfunction. The most common precipitations of geriatric DKA were infections (70.1 %), followed by treatment non-adherence (66.2 %) and non-infectious disorders (35.1 %). Infections and non-infectious disorders were significantly more frequent in elderly patients than in non-elderly patients. Respiratory and urinary tract infections were prevalent in both age groups. In-hospital survival was 74.9 % (n = 415) and remained lower in older patients (48.1 % vs. 79.2 %, P-value <0.001). The independent prognostic factors were age (OR 1.030, 95 % CI 1.006-1.054, P = 0.014), Glasgow coma scale (OR 0.789, 95 % CI 0.717-0.869, P <0.001), and infection trigger (OR 6.635, 95 % CI 2.852-15.441, P <0.001). CONCLUSION: Older patients with DKA present atypically, frequently have precipitation with infections and noninfectious disorders, and have poor outcomes.

Efficacy, safety, and dose-response effects of calcifediol supplementation on 25-hydroxyvitamin D, parathyroid hormone, and 1,25-dihydroxyvitamin D levels in healthy adults: An open-label, interventional pilot study.

BACKGROUND: Vitamin D deficiency (VDD) is highly prevalent across the globe. Cholecalciferol (Vitamin D3) fails to attain sufficient serum concentrations of 25-hydroxyvitamin D (25(OH)D) in a significant proportion of supplemented individuals. Calcifediol (25-hydroxyvitamin D3) is less studied in healthy adults and its effects on 25(OH)D, parathyroid hormone (PTH), and 1,25-dihydroxyvitamin D (1,25(OH)2D) at higher doses are not well known. MATERIALS AND METHODS: The study was an open-label, interventional trial recruiting consecutive participants with VDD who were allocated to receive either 2 capsules (50 µg-group) or 1 capsule (25 µg-group) daily doses of calcifediol. Baseline assessment included clinicodemographic parameters, dietary calcium, calcemic (calcium, inorganic phosphate, albumin, alkaline phosphatase, urine spot calcium/creatinine), and hormonal parameters (25(OH)D, PTH, and 1,25(OH)2D). Participants were followed up at 4 and 8 weeks with repeat assessments of calcemic and hormonal parameters. RESULTS: There were 64 participants, 35 (50 µg-group) and 29 (25 µg-group), without any significant difference in any of the baseline parameters. 97.1% participants in the 50 µg-group (at 4 and 8 weeks) and 93.1% (at 4 weeks) and 96.5% (at 8 weeks) in the 25 µg-group attained 25(OH)D sufficiency (≥30 ng/ml) with calcifediol. The mean serum 25(OH)D was 84.0 ± 27.7 ng/ml in the 50 µg-group and 58.0 ± 23.6 ng/ml in the 25 µg-group group at 4 weeks, which later rose to 94.3 ± 21.8 ng/ml and 76.0 ± 16.4 ng/ml, respectively, at 8 weeks. PTH levels decreased in both groups at both time points. 1,25(OH)2D rose significantly in both groups at 4 and 8 weeks but was not significantly different between both groups. There was no case of incident hypercalcemia or symptomatic nephrolithiasis. CONCLUSION: Calcifediol is a safe and efficacious alternative for oral Vitamin D supplementation in young adults. Increment in 25(OH)D levels is rapid and dose-dependent.

Sellar Suprasellar Surprise: A Rare Case of Atypical Teratoid/Rhabdoid Tumor in an Infant.

We present a case of a 10-month-old male infant who initially presented with polyuria, polydipsia, drowsiness, and fever. Neuroimaging using non-contrast computed tomography (NCCT) demonstrated obstructive hydrocephalus associated with a suprasellar mass, for which emergency neurosurgical intervention was performed with right parietal medium pressure ventriculoperitoneal (MPVP) shunting. For fever, no cause was found with sterile cerebrospinal fluid (CSF) analysis, and empirical antibiotics were administered. The patient exhibited polyuria with hypernatremia and was diagnosed with arginine vasopressin (AVP) deficiency, further complicated by visual impairment due to left optic atrophy. Hormonal workup revealed secondary hypothyroidism and hypocortisolism. Imaging by contrast-enhanced magnetic resonance imaging (CEMR) revealed a lobulated solid-cystic suprasellar mass with flow void, suggestive of adamantinomatous craniopharyngioma initially. However, despite multiple neurosurgical interventions, the patient's condition deteriorated with recurrent fever and seizures, leading to a revision of ventriculoperitoneal shunts. Repeat CEMR showed an increase in the size of the lesion with spinal leptomeningeal metastasis, suggesting a different pathology. Transventricular biopsy confirmed an atypical teratoid and rhabdoid tumor (AT/RT), World Health Organization Classification of Tumors of the Central Nervous System (CNS WHO) grade 4, characterized by diffuse growth pattern, moderate nuclear pleomorphism, clear cytoplasm, and prominent nucleoli. Immunohistochemistry revealed positive vimentin staining and loss of integrase interactor 1 (INI1) expression, consistent with AT/RT. The patient's parents were counseled on the need for multimodal management, including surgery and chemotherapy. However, due to socioeconomic constraints and a guarded prognosis, they chose to leave against medical advice. This case illustrates the diagnostic challenges in distinguishing AT/RT from other suprasellar masses and emphasizes the importance of a multidisciplinary approach in managing complex pediatric cases.

A Rare Case of Headache in a Patient With McCune-Albright Syndrome: A Triple Threat.

A 26-year-old male presented with facial asymmetry since 11 years of age and painless progressive diminution of vision in the left eye since 16 years of age. He presented with an exacerbation of headaches for the past two months. On examination, he was tall and had acral enlargement, craniofacial deformity, and bilateral asymmetric testicular enlargement. Investigations revealed high insulin-like growth factor 1, non-suppressible growth hormone on oral glucose tolerance tests, and multiple pituitary hormone deficiencies. MRI showed pituitary macroadenoma with craniofacial and sphenoid fibrous dysplasia as well as multiple tuberculomas. Cerebrospinal fluid testing showed high protein, low glucose, and high adenosine deaminase, all consistent with a diagnosis of central nervous system (CNS) tuberculosis. His headache did not respond significantly to either octreotide or zoledronic acid. The patient was then initiated on antitubercular therapy, which led to near-complete resolution of the headache and CNS lesions within three months of therapy. CNS tuberculosis was a masquerader in the index case of acrogigantism due to McCune-Albright syndrome. Headaches may be multifactorial in a given case of acromegaly, and investigating for alternative or additional causes especially when dealing with treatment-refractory cases can be rewarding.

Unusual and lesser-known rare causes of adult growth hormone deficiency.

Growth hormone is among the most common hormones to be deficient in pituitary insult. It can occur either in isolation or combined with other hormone deficiencies. Growth hormone deficiency in adults (AGHD) can be due to causes acquired in adulthood or have a childhood-onset etiology, but the former is about three times more common. Usual causes of AGHD include mass effects due to a pituitary tumour, and/or its treatment (surgery, medical therapy, or radiotherapy), or radiotherapy to the head and neck region for non-pituitary lesions. The unusual or lesser-known causes of AGHD, are usually due to non-tumoral etiology and range from vascular and infective to inflammatory and miscellaneous causes. These not only expand the spectrum of AGHD but may also contribute to increased morbidity, adverse metabolic consequences, and mortality due to the primary condition, if unrecognised. The review features these lesser-known and rare causes of AGHD and highlights their clinical and diagnostic implications.

Normative Data on Dehydroepiandrosterone Sulphate (DHEAS) and its Attributes in Healthy Indian Children and Adolescents.

Dehydroepiandrosterone sulphate (DHEAS), the biochemical indicator of adrenarche and pubarche, is of paramount importance in the evaluation of puberty-related disorders. The reference range of DHEAS should be ethnicity, age, sex, pubarche and Tanner stage specific. Anthropometry, puberty assessment and hormonal parameters were estimated using electrochemiluminescence assay. Bone age was estimated using the BoneXpert software. Of 2191 healthy Indian children aged 5-18 y screened at Chandigarh, 1919 were included in the final analysis (994 boys). The median DHEAS levels at pubarche stage P2 were 82.10 (55.0-129.0) g/dl in girls and 132.50 (95.12-205.50) g/dl in boys. By ROC analysis, the level of DHEAS at pubarche was 63.7 g/dl (sensitivity 72.6%, specificity 64.4%) in girls and 82.2 g/dl (sensitivity 81.8%, specificity 68.8%) in boys. The median age at adrenarche was 9.5 y in both sexes. On multivariate regression analysis; bone age, body mass index (BMI), gonadal steroids, and insulin-like growth factor-1 (IGF-1) significantly correlated with serum DHEAS levels in either sex.

Diagnostic utility of procalcitonin for bacterial infections in diabetic ketoacidosis.

Procalcitonin is a widely used infection biomarker; however, its utility in identifying bacterial infection in diabetic ketoacidosis (DKA) is unclear. We aimed to evaluate its diagnostic performance for detecting DKA cases triggered by bacterial infections. We reviewed 303 case records of patients aged ≥ 13 years with DKA admitted to the emergency department, PGIMER (Chandigarh), between 2017 and 2022. Baseline procalcitonin was measured by electrochemiluminescence immunoassay, and a value > 0.5 ng/mL was considered elevated. Both microbiological reference standard (MRS) and composite reference standard (CRS) were used to evaluate the diagnostic performance of procalcitonin. 151/303 (49.8%) DKA cases had infection precipitations. Bacterial infections were present in 98 patients (53 microbiologically confirmed), of which urinary tract infection (n = 42), pneumonia (n = 19), skin and soft-tissue infection (n = 13), and bacteremia (n = 11) were common. The median value of procalcitonin was higher with bacterial infections than in patients without (3.68 vs. 1.00, P-value < 0.001). An elevated procalcitonin to detect bacterial infections in DKA had sensitivity 84.69%, specificity 34.15%, positive likelihood ratio (LR +) 1.29, and negative likelihood ratio (LR -) 2.44, against CRS. Against MRS, both LR + and LR - further decreased to 1.23 and 1.81, respectively. Using the receiver-operating-characteristic curve, an optimal cut-off of procalcitonin was calculated at 1.775 ng/ml against both CRS (area under curve 0.655, sensitivity 68.37%, specificity 59.02%, LR + 1.67, LR - 1.86, Yoden's index 0.274) and MRS (area under curve 0.616, sensitivity 67.92%, specificity 59.02%, LR + 1.66, LR - 1.84, Yoden's index 0.269). Procalcitonin does not help detect bacterial infections in patients with DKA at admission.

Autonomous growth hormone secretion due to McCune Albright syndrome in paediatric age group: an ominous triad.

PURPOSE: The current study aimed to report cases of McCune Albright syndrome (MAS) with growth hormone (GH) hyper secretion along with a systematic review of literature to elucidate challenges and intricacies in its diagnosis and management. METHODS: It was a single centre study carried out in individuals with MAS and autonomous GH secretion (AGHS). In addition, a systematic search of literature across three databases (PubMed, Scopus and EMBASE) was performed from inception until May 31, 2021 to identify cases of MAS with AGHS in the pediatric age group (<18 years). RESULTS: Three cases from authors centre and 42 cases identified from systematic literature review were analysed. Precocious puberty was the most common presenting endocrinopathy seen in 56.8% (25/44) cases, followed by hyperthyroidism (10/45), hypophosphatemia (4/45), and hypercortisolism (2/45). Cranio-facial fibrous dysplasia (CFFD) was seen in all while polyostotic fibrous dysplasia and Café au lait macule was seen in 40/45 (88.9%) and 35/45 (77.8%), respectively. Pituitary adenoma (58.3% microadenoma) was localized in 53.3% (24/45) cases on pituitary imaging. Biochemical and clinical remission of AGHS was achieved in 61.5% (24/45) cases with medical therapy. CONCLUSION: Diagnosing AGHS in MAS is challenging because of concomitant presence of CFFD, non-GH endocrinopathies associated height spurt and elevated serum IGF-1. GH-GTT should be performed in presence of elevated growth velocity and serum IGF-1 (>1 X ULN) despite adequate control of non-GH endocrinopathies. Medical management can lead to disease control in substantial number of cases and often entails use of multiple agents.

Impulse Control Disorders with Short-term Use of Cabergoline in Macroprolactinomas: A Prospective Study with a Brief Review of Literature.

Impulse control disorders (ICDs) are less-emphasized adverse effects of dopamine agonists. Evidence on prevalence and predictors of ICDs in patients with prolactinomas is limited and confined chiefly to cross-sectional studies. This was a prospective study performed to investigate ICDs in treatment-naïve patients with macroprolactinomas (n = 15) using cabergoline (Group I), compared to consecutive patients of nonfunctioning pituitary macroadenomas (n = 15) (Group II). Clinical, biochemical, radiological parameters and psychiatric comorbidities were evaluated at baseline. ICD was assessed by Minnesota impulsive disorder interview, modified hypersexuality and punding questionnaires, South Oaks gambling scale, kleptomania symptom assessment scale, Barratt impulsive scale (BIS), and internet addiction scores (IAS) at baseline and 12 weeks. Group I had a significantly lower mean age (28.5 vs. 42.2 years) with a female predominance (60%) compared to group II. Median tumor volume was lower in group I (4.92 vs. 14 cm3) despite significantly longer symptom duration (2.13 vs. 0.80 years) than in group II. Serum prolactin decreased by 86% (P = 0.006) and tumor volume decreased by 56% (P = 0.004) at 12 weeks in group I, with a mean weekly cabergoline dose of 0.40 ± 0.13 mg. There was no difference between both groups in hypersexuality, gambling, punding, and kleptomania symptom assessment scale scores at baseline and 12 weeks. Mean BIS showed a more remarkable change in group I (16.2% vs. 8.4%, P = 0.051), and 38.5% of patients transitioned from average to above-average IAS in group I. The current study found no increased risk of ICD with short-term use of cabergoline in patients with macroprolactinomas. The use of age-appropriate scores (such as IAS in younger individuals) may help diagnose subtle alterations in impulsivity.
