The article offers a glimpse of pheochromocytona and paraganglioma (PPGL) management through ambulatory blood pressure monitoring (ABPM), with reference to a study on ABPM in PPGL in patients on amlodipine. It points out the challenge in the surgical management of PPGL and offers reminders about the use of calcium channel blockers as monotherapy, high-sodium diet and fluid intake. The efficacy of preoprative blockade with amlodipine in preventing hemodynamic instability in PPGL is discussed.

Background: The role of bisphosphonates (BP) in hypertrophic osteoarthropathy (HPOA) is unclear. We presented a case of primary HPOA and performed a systematic review of literature on the effect of BP on treatment response in primary and secondary HPOA., Methods: The study was prospectively registered in PROSPERO (CRD42022343786). We performed a PubMed literature search that restricted to the English language. We included patients diagnosed with primary or secondary HPOA who received BP. The primary endpoint assessed was the effectiveness of BP on response to pain or arthritis. Secondary outcomes included timing, degree, and duration of response, comparison to other HPOA therapies, impact of BP on radiology, bone scan, bone turnover markers, and adverse effects of BP., Results: Literature search retrieved only case reports. Forty-five patients (21 primary, 24 secondary HPOA) had received BP. Majority(88.3%) experienced improvement in pain or arthritis. Response was gradual for primary HPOA and within a median of 3 to 7 days for secondary HPOA after treatment with BP. Most patients had reduced bone scan uptake after BP. When other HPOA therapies were tried, half responded to BP after not having previously responded to other therapies, while a third received the treatments concurrently, making it difficult to attribute treatment response to a drug. Reporting of other secondary outcomes was very heterogenous and qualitative to draw conclusions. No major adverse effects have been reported for BP in HPOA., Conclusion: Bisphosphonates provide an effective and safe treatment option for primary and secondary HPOA. However, there is a lack of randomized controlled trials., (© 2024. The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.)

Objectives: To evaluate the clinical, hormonal and genetic characteristics of 46XY disorders of sexual development (DSD) patients from South India., Methods: 46XY DSD patients with a provisional diagnosis of 17β-hydroxysteroid dehydrogenase 3 (17BHSD3) deficiency, 5 alpha-reductase type 2 deficiency (5ARD2) or partial androgen insensitivity syndrome (PAIS) based on clinical and hormonal analysis were included in this study. All the patients underwent detailed clinical and hormonal evaluations. Targeted next-generation sequencing for all three genes (AR, HSD17B3, and SRD5A2) in parallel was carried out for all the included patients and their parents., Results: Based upon the clinical and hormonal analysis, among the 37 children with 46XY DSD in the present study, 21 children were diagnosed with 5ARD2, 10 with PAIS, and six with 17BHSD3 deficiency. However, genetic analysis revealed pathogenic mutations in nine patients - six in the AR gene, two in the SRD5A2 gene, and one in the HSD17B3 gene. The concordance rate between provisional hormonal and genetic diagnosis was only 22.2%. Two out of six subjects with AR gene variants were positive for somatic mosaicism., Conclusions: In the present study, a positive genetic diagnosis was detected in nine patients (24%), including five novel variants. In this study, mutations in the AR gene was the most reported. The authors did not find the testosterone: dihydrotestosterone (T: DHT) ratio to be an accurate hormonal diagnostic tool., (© 2024.

Introduction: The aim of this study was to compare insulin sensitivity, islet cell function, and incretin axes in pregnant subjects with GDM and normal healthy controls., Methods: Pregnant women at 24 to 28 weeks of gestation were subjected to a 75 g oral glucose tolerance test (OGTT). Samples for glucose, insulin, glucagon, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) were collected at 0, 30, 60, and 120 min during the OGTT. The Matsuda index (MI) and insulin secretion and sensitivity index-2 (ISSI-2) were assessed. The glucagon suppression index (GSI) was calculated along with the area under the curve (AUC) for glucose, insulin, glucagon, GLP-1, and GIP., Results: A total of 48 pregnant women (25 GDM and 23 controls) were finally analysed. The MI and ISSI-2 were low in the GDM group [4.31 vs. 5.42; P = 0.04], [1.99 vs. 3.18, P ≤ 0.01] respectively). Total AUC glucagon was higher in the GDM group (7411.7 vs. 6320.1, P = 0.02). GSI 30 was significantly lower in the GDM group (-62.6 vs. -24.7, P = 0.03). Fasting GLP-1 levels were low in GDM women (17.3 vs. 22.2, P = 0.04). The total AUC GLP-1 positively correlated with total GSI in the GDM group., Conclusion: Asian-Indian GDM women have high insulin insensitivity, islet cell dysfunction, and low fasting GLP-1. Incretin axis dysfunction plays a potential role in their islet cell dysfunction., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Indian Journal of Endocrinology and Metabolism.)

Background: The severe acute respiratory syndrome coronavirus 2 can affect the hypothalamic-pituitary-gonadal axis (HPG) due to the expression of the angiotensin-converting enzyme 2 receptor., Objectives: To assess the prevalence of hypogonadism and Sertoli cell dysfunction in coronavirus disease 2019 (COVID-19) male survivors., Method: Male subjects recovered from acute COVID-19 infection were prospectively observed. The primary outcomes included the proportion of hypogonadism, defined biochemically as serum testosterone<230 ng/dL or CFT of<6.4 ng/mL if the total testosterone is between 230-320 ng/m. Sertoli cell dysfunction was defined as inhibin-B level<54.5 pg/mL. Subjects with hypogonadism were followed up at 12 months to assess the recovery of the HPG axis., Results: Eighty-three subjects aged≥18 years were evaluated at a median of 120 (±35) days post-recovery. Their mean age was 49.50±12.73 years, and the mean BMI was 26.84±5.62 kg/m 2 . Low testosterone was detected in 21 (24.71%) and low inhibin-B was detected in 14 (19.71%) out of 71 subjects at 3 months. Subjects with low testosterone were younger, with a mean age of 43.29±12.03 years (P-0.08) and higher BMI (P-0.012). The severity of COVID-19 infection, duration of hospitalization, and other factors were not significantly associated with low testosterone. At 12 months, 18 out of 21 subjects came for follow-up, of which 9 (50%) showed persistently low testosterone, suggestive of hypogonadism., Conclusion: Following COVID-19 infection, testosterone levels recovered over time; however, a significant proportion of subjects had low levels at 12-month follow-up. These findings have long-term implications for the management of COVID-19 subjects., Competing Interests: The authors declare no competing interests., (Thieme. All rights reserved.)

Purpose: Literature on the treatment of pre-transplant hepatic osteodystrophy (HOD) is limited. The general treatment measures and their timing are currently adopted from the literature on postmenopausal osteoporosis. Therefore, we conducted this randomized study to investigate the effect of zoledronic acid (ZA) on HOD., Methods: We randomized 36 male patients with cirrhosis (Child-Pugh class A and B) into 19 to the ZA arm and 17 to the placebo arm, respectively. Patients in the ZA arm received a single infusion of 4 mg ZA dissolved in 100 mL of normal saline at baseline, while patients in the placebo arm received a similar infusion of normal saline at baseline. The primary outcome of the study was the change in lumbar spine bone mineral density (LS-BMD) at 12 months., Results: Of 36 patients, 28 completed the study (15 in the ZA arm and 13 in the placebo arm). The mean increase in LS-BMD (g/cm 2 ) in the ZA and placebo arms was 5.11% (3.50) and 0.72% (4.63) [ P = 0.008], respectively. The trabecular bone score (TBS) did not improve significantly in either arm. The incidence of vertebral fractures (VFs) was similar in both arms. There was a significant decrease in plasma beta-C-terminal telopeptide (β-CTX) levels in the ZA arm compared to the placebo arm, while the change in plasma levels of procollagen 1 intact N-terminal propeptide (P1NP) was similar in both arms. Six patients (31.6%) in the ZA arm experienced adverse reactions such as fever and myalgia., Conclusion: ZA improved LS-BMD in male patients with HOD by decreasing bone resorption. However, it may not improve trabecular microarchitecture or prevent morphometric VFs in this population., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Indian Journal of Endocrinology and Metabolism.)

Objective: To study the association of fetal growth restriction (FGR) with metabolic bone disease in preterm neonates., Methodology: This prospective cohort study included 94 preterm neonates with FGR as cases and an equal number of gestation-matched appropriate for gestational age (AGA) neonates without FGR as controls. The incidence of metabolic bone disease, and serum biochemical markers at various time intervals till 6 months corrected age were compared. The risk factors for metabolic bone disease and its association with stunting at 6 months of corrected age were studied., Results: The incidence of metabolic bone disease, though higher in the FGR neonates (15.5%), was not significantly different from AGA neonates (6.7%) [RR (95%CI) 0.92-5.82; P=0.06]. Birth weight [aOR (95%CI) 0.8 (0.64-0.98); P=0.03] and time to reach full feeds [aOR (95%CI) 1.17 (1.01-1.36); P=0.03] were significantly associated with an increased risk of metabolic bone disease after adjusting for FGR status. Mean (SD) levels of calcium, phosphorus, alkaline phosphatase, parathormone (PTH), and vitamin D were similar in both groups. No significant association existed between metabolic bone disease and stunting at 6 months of corrected age [RR (95%CI) 2 (0.75-5.4); P=0.16]., Conclusion: FGR was not found to be significantly associated with metabolic bone disease in preterm neonates.

Purpose: The objectives were to study the effect of a single dose of intravenous (IV) zoledronic acid (ZA) on changes in bone mineral density (BMD) (lumbar spine (LS), hip, & distal forearm), trabecular bone score (TBS) and bone turnover markers (BTMs) in postmenopausal osteoporotic women with and without diabetes over 12 months., Methods: Patients were divided into two groups: type 2 diabetes mellitus (T2DM) (n = 40) and non-DM (n = 40). Both groups received a single dose of 4 mg IV ZA at baseline. The BMD with TBS and BTMs (β-CTX, sclerostin, P1NP) were measured at baseline, six months, and 12 months., Results: At baseline, BMD in all three sites was similar in both groups. T2DM patients were older and had lower BTMs than non-DM patients. The mean increase in LS-BMD (gram/cm 2 ) at 12 months in T2DM and the non-DM group was 3.6 ± 4.7% and 6.2 ± 4.7 %, respectively (P = 0.01). However, the age adjusted mean difference in LS BMD increment between two groups at one year was - 2.86 % (-5.02% to -0.69%), P = 0.01. There was a comparable change in BMD at other two sites, BTMs, and TBS in both the groups over one year follow-up., Conclusion: The gain in the LS-BMD was significantly lower in T2DM group compared to non-DM subjects over 12 months after a single IV infusion of 4 mg ZA. The explanation for this could be low bone turnover in diabetes subjects at baseline., (© 2023.

Background: Dyslipidemia is an important comorbid factor of type 2 diabetes mellitus (T2DM) that increases the risk of cardiovascular diseases. This study aimed to assess the pattern of dyslipidemia and atherogenic indices and determine its relation with glycemic control., Methods: A cross-sectional study enrolled 382 patients with diabetic dyslipidemia. The socio-demographics data, clinical features, and laboratory parameters were collected. The baseline lipid parameters such as total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and glycated hemoglobin (HbA1C) were measured. Atherogenic indices such as TC/HDL-C ratio, TG/HDL-C ratio, LDL-C/HDL-C ratio, non-HDL-C/HDL-C and atherogenic index of plasma (AIP) [log10 (TG/HDL-C)] were calculated. T2DM patients were classified into three groups based on the degree of glycemic control: Good glycemic control (HbA1C<7%), fair control (HbA1C 7-8%), and poor control (HbA1C>8%)., Results: The population's mean age was 48.60±6.15 years, with 145 (38%) males. We found mixed dyslipidemia as the most prevalent (36.1%) form of dyslipidemia in our patients. The most common pattern in atherogenic indices was AIP (94.2%). HbA1c was positively correlated with duration of diabetes (r = 0.253, p<0.001). In multivariate logistic regression analysis, duration of diabetes (>10 years) was significantly associated with poor glycemic control with an odds ratio (OR) of 2.31(95% CI; 1.25-4.24, p=0.007)., Conclusion: The present study indicated that neither the pattern of dyslipidemia nor the atherogenic indices were markers of poor glycemic control among South Indian patients attending our tertiary care institute. However, duration of diabetes was significantly associated with poor glycemic control., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Bage et al.)

Objective: The aim of this study was to evaluate the difference in mean serum 25-hydroxy vitamin D level between migraineurs and nonmigraineurs, the association between hypovitaminosis D and migraine, and the effects of oral vitamin D supplementation on migraine-related symptoms as compared to placebo., Methods: Relevant databases were searched for observational studies and randomized-controlled trials (RCTs) which evaluated the difference in mean serum 25-hydroxy vitamin D level between migraineurs and nonmigraineurs; the association between hypovitaminosis D and migraine; and the effects of vitamin D supplementation on migraine-frequency, duration, and severity. Pooled mean difference and odds ratio were calculated (random-effects model, RevMan version 5.3)., Results: Ten observational studies and two RCTs were included. The serum 25-hydroxy vitamin D level in the migraineurs was significantly lower than that in the nonmigraineurs [mean difference - 4.44 ng/mL (95% CI: -6.11, -2.77)] (low-GRADE evidence). Hypovitaminosis D was found to be significantly associated with migraine [OR: 1.95 (95% CI: 1.07, 3.58)] (low-GRADE evidence). As compared to placebo, oral vitamin D supplementation significantly reduced the monthly migraine-frequency [mean difference: -2.20 (95% CI: -3.04, -1.36)]., ,: although it did not reduce the migraine-duration [mean difference: -16.00 hours per month (95% CI: -42.77, 10.76)] and migraine-severity score [standardized mean difference: -0.23 (95% CI: -0.79, 0.32)] (moderate-GRADE evidence)., Conclusion: Serum 25-hydroxy vitamin D level was significantly lower in the migraineurs than that in the nonmigraineurs, and hypovitaminosis D was significantly associated with migraine. Oral vitamin D supplementation significantly reduced migraine-frequency, but not its duration and severity., Competing Interests: None

Premature ovarian insufficiency (POI) is a common cause of infertility in women, characterised by amenorrhea and elevated FSH under the age of 40 years. In some cases, POI is syndromic in association with other features such as sensorineural hearing loss in Perrault syndrome. POI is a heterogeneous disease with over 80 causative genes known so far; however, these explain only a minority of cases. Using whole-exome sequencing (WES), we identified a MRPL50 homozygous missense variant (c.335T > A; p.Val112Asp) shared by twin sisters presenting with POI, bilateral high-frequency sensorineural hearing loss, kidney and heart dysfunction. MRPL50 encodes a component of the large subunit of the mitochondrial ribosome. Using quantitative proteomics and western blot analysis on patient fibroblasts, we demonstrated a loss of MRPL50 protein and an associated destabilisation of the large subunit of the mitochondrial ribosome whilst the small subunit was preserved. The mitochondrial ribosome is responsible for the translation of subunits of the mitochondrial oxidative phosphorylation machinery, and we found patient fibroblasts have a mild but significant decrease in the abundance of mitochondrial complex I. These data support a biochemical phenotype associated with MRPL50 variants. We validated the association of MRPL50 with the clinical phenotype by knockdown/knockout of mRpL50 in Drosophila, which resulted abnormal ovarian development. In conclusion, we have shown that a MRPL50 missense variant destabilises the mitochondrial ribosome, leading to oxidative phosphorylation deficiency and syndromic POI, highlighting the importance of mitochondrial support in ovarian development and function., (© 2023.

Diabetes mellitus (DM) is characterized by persistently elevated blood glucose concentration that lead to multisystem complications. There are about 400 medicinal plants cited to have a beneficial effect on DM. We must choose products wisely based on data derived from scientific studies. However, a major obstacle in the amalgamation of herbal medicine in modern medical practices is the lack of clinical data on its safety, efficacy and drug interaction. Trials of these herbal products often underreport the side effects and other crucial intervention steps deviating from the standards set by Consolidated Standards of Reporting Trials. Due to a lack of knowledge of the active compounds present in most herbal medicines, product standardization is difficult. Cost-effectiveness is another issue that needs to be kept in mind. In this mini-review, we focus on the anti-hyperglycemic effect of herbal products that are commonly used, along with the concerns stated above., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2023.

Genetic selection can be a feasible method to help mitigate enteric methane emissions from dairy cattle, as methane emission-related traits are heritable and genetic gains are persistent and cumulative over time. The objective of this study was to estimate heritability of methane emission phenotypes and the genetic and phenotypic correlations between them in Holstein cattle. We used 1765 individual records of methane emission obtained from 330 Holstein cattle from two Canadian herds. Methane emissions were measured using the GreenFeed system, and three methane traits were analyzed: the amount of daily methane produced (g/d), methane yield (g methane/kg dry matter intake), and methane intensity (g methane/kg milk). Genetic parameters were estimated using univariate and bivariate repeatability animal models. Heritability estimates (±SE) of 0.16 (±0.10), 0.27 (±0.12), and 0.21 (±0.14) were obtained for daily methane production, methane yield, and methane intensity, respectively. A high genetic correlation (rg = 0.94 ± 0.23) between daily methane production and methane intensity indicates that selecting for daily methane production would result in lower methane per unit of milk produced. This study provides preliminary estimates of genetic parameters for methane emission traits, suggesting that there is potential to mitigate methane emission in Holstein cattle through genetic selection.

Background: Peroxisome proliferator-activated receptors (PPAR) α and γ genes play an important role in dyslipidaemia of T2DM., Aims: To estimate the frequency distribution of PPAR α and γ gene polymorphisms in South Indian T2DM patients with dyslipidaemia compared to healthy controls. Normative frequencies of SNPs were established and compared with data for 1000 genome populations., Methods: Eligible 382 cases and 336 age and sex-matched controls were enrolled. Six SNPs in PPARα [rs1800206 C>G (Leu162Val), rs4253778 G>C, rs135542 T>C] and PPARγ [rs3856806 (C>T), rs10865710 (C>G), rs1805192 C>G (Pro12Ala)] genes were selected for genotyping., Results: The allele and gene frequencies did not significantly differ between the diabetic dyslipidaemia cases and healthy controls. However, they were significantly different from that of 1000 genome populations except for rs1800206 C>G (Leu162Val) and rs1805192 C>G (Pro12Ala)., Conclusion: The studied polymorphisms in PPARα and PPARγ genes are not associated with diabetic dyslipidaemia among South Indian patients., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Indian Journal of Endocrinology and Metabolism.)

Thyroid gland can be affected by the COVID-19 infection. The pattern of thyroid function abnormality reported in COVID-19 is variable; in addition, some drugs used in COVID-19 patients like glucocorticoids and heparin can affect the thyroid function tests (TFT). We conducted an observational, cross-sectional study of thyroid function abnormalities with thyroid autoimmune profile in COVID-19 patients with varying severity from November 2020 to June 2021. Serum FT4, FT3, TSH, anti-TPO, and anti-Tg antibodies were measured before the initiation of treatment with steroids and anti-coagulants. A total of 271 COVID-19 patients were included in the study, of which 27 were asymptomatic and remaining 158, 39, and 47 were classified to mild, moderate and severe categories, respectively, according to MoHFW, India criteria. Their mean age was 49±17 years and 64.9% were males. Abnormal TFT was present in 37.2% (101/271) patients. Low FT3, low FT4, and low TSH were present in 21.03%, 15.9% and 4.5% of patients, respectively. Pattern corresponding to sick euthyroid syndrome was the most common. Both mean FT3 and FT3/FT4 ratio decreased with increasing severity of COVID-19 illness (p=0.001). In multivariate analysis, low FT3 was associated with increased risk of mortality (OR 12.36, 95% CI: 1.23-124.19; p=0.033). Thyroid autoantibodies were positive in 58 (27.14%) patients; but it was not associated with any thyroid dysfunction. Thyroid function abnormality is common among COVID-19 patients. Both low FT3 and FT3/FT4 ratio are indicators of disease severity while low FT3 is a prognostic marker of COVID-19 associated mortality., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Growth hormone (GH) excess is associated with several systemic complications, one of which is the increased risk of neoplastic processes particularly of the gastrointestinal (GI) tract. Among the GI neoplasms, the most reported association is with benign and malignant neoplasms of the colon. In the majority of published literature, an increased incidence of GI neoplasms, both colonic adenomas as well as colorectal carcinoma is reported. However, the studies on colon cancer-specific mortality rate are conflicting with recent studies reporting similar cancer-specific mortality rates in comparison to controls. Many studies have reported an association of colorectal neoplasms with GH levels. Pathogenic mechanisms put forward to explain this association of GH excess and GI neoplasms primarily involve the increased GH-insulin-like growth factor 1 (IGF-1) signaling. Both GH and IGF-1 have proliferative, anti-apoptotic, and angiogenic effects on the systemic tissues leading to cellular proliferation. Other contributing factors to the increased risk of GI neoplasms include slow intestinal transit with a redundant large bowel, altered bile acids, deranged local immune response, shared genetic susceptibility factors and hyperinsulinemia. In view of the increased risk association, most guidelines for the care of acromegaly patients recommend an initial screening colonoscopy. Recommendations for further follow-up colonoscopy differ but broadly, the guidelines agree that it depends on the findings at first colonoscopy and state of remission of GH excess. Regarding the concern about the risk of colorectal cancers in patients receiving recombinant GH therapy, most cohort studies do not show an increased risk., Competing Interests: Conflict-of-interest statement: All authors have no conflicts of interest to declare., (©The Author(s) 2023.

This study was performed to evaluate the efficacy of cholecalciferol in improving renal and vascular functions in vitamin D-deficient patients with type 2 diabetes mellitus (T2DM) along with chronic kidney disease (CKD). One hundred patients (18 - 65 years), having T2DM along with CKD (stage IIIA and IIIB) and hypovitaminosis D were randomized (1:1) to receive either oral cholecalciferol 60,000 IU (Group A) or placebo (Group B) weekly for 8 weeks along with standard background treatment. They were followed up for another 24 weeks. Various parameters of renal and vascular functions were compared. Except for serum calcium and phosphate levels which were significantly higher in Group A ( p  < 0.001), there was no significant difference in any of the biochemical or vascular parameters between the two groups at 8 weeks. There were comparable changes in urinary albumin-creatinine ratio and carotid-femoral pulse wave velocity in the two groups at 8 and 24 weeks. There was no improvement in any of the vascular parameters from the corresponding baseline values in the two groups at 8 and 32 weeks. No improvement in renal and vascular functions was observed following treatment with oral cholecalciferol in patients with T2DM and CKD.

Context: Primary hyperparathyroidism (PHPT) can occur due to a neoplastic process or hyperplasia. While the disease presentation is predominantly asymptomatic in developed countries, this is not the case yet in India. Differentiation of the type of lesion can only be done based on histomorphology but has its own challenges. Immunohistochemical markers like Ki-67 have been studied to aid in diagnosis but data on this is sparse from India., Aims: The aim of this study is to assess the clinical, biochemical and pathological profile of PHPT and to analyse the differences in immunohistochemical marker Ki-67 among the various lesions., Setting and Design: A descriptive study was carried out on 38 PHPT patients who were treated at our institute from January 2011 to March 2021., Materials and Methods: Post-surgery, the causative lesions were categorised as adenoma (31), hyperplasia (5) and carcinoma (2). Clinical, biochemical, radiological and histopathological features of all lesions were collected and analysed. Ki-67 proliferation index was calculated. The various parameters were compared across the three groups of lesions and correlated with Ki-67 index., Results: Out of 38 patients, 37 were symptomatic with skeletal symptoms being the most common followed by renal symptoms. There was no difference in clinical or biochemical parameters among the three types of lesions. Significant negative correlation was seen between serum iPTH and serum 25-OH Vitamin D levels ( P0.006) The median Ki-67 index was found to be 0.40% in hyperplasia, 0.49% in adenoma and 5.84% in carcinoma., Conclusion: PHPT still presents as an overtly symptomatic disease in India. Diagnosis of the nature of lesion depends on the accurate application of morphological criteria. A high Ki-67 index was not found to be an absolute marker of carcinoma, as it was also seen in a small proportion of atypical adenomas., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Indian Journal of Endocrinology and Metabolism.)

Coronavirus disease 2019 (COVID-19) is associated with a high risk of mortality and complications in patients with diabetes mellitus. Achieving good glycemic control is very important in diabetic patients to reduce complications and mortality due to COVID-19. Recent studies have shown the mortality benefit and anti-inflammatory effects of Dipeptidyl-peptidase-4 inhibitors (DPP-4i) in diabetic patients with COVID-19. DPP-4i may have a beneficial role in halting the severity of infection primarily by three routes, namely viral entry inhibition, anti-inflammatory and anti-fibrotic effects and glycemic control. This has raised the pro-mising hypothesis that DPP-4i might be an optimal strategy for treating COVID-19 in patients with diabetes. This review aims to summarise the possible therapeutic non-glycemic effects of DPP-4i in diabetic patients diagnosed with COVID-19 in the light of available evidence., Competing Interests: Conflict-of-interest statement: All authors have no conflicts of interest to report., (©The Author(s) 2022.

Background: Snakebite envenomation (SE) is an important tropical disease in India, causing significant morbidity and mortality among patients. The hormonal deficiencies due to the involvement of the pituitary in case of SE can present in either acute or delayed setting. Hypopituitarism (HP) is often an underrecognized and relatively rarely reported complication of this neglected disease., Methods: We present here the data of 15 patients diagnosed to have HP following systemic SE and are being currently followed-up in the Endocrinology outpatient department of a tertiary care hospital of South India. The study was approved by the Institute ethics committee, and informed onsent was taken from all the study patients. The study was a record-based retrospective analysis of the patients with HP following SE. Clinical data including lag time in diagnosis and type of snake were determined. Further, hormonal data including all the anterior pituitary functions (thyroid stimulating hormone, free T4, cortisol, insulin-like growth factor (IGF-1) luteinizing hormone, follicular-stimulating hormone, testosterone; prolactin) and water deprivation test to determine diabetes insipidus (DI) in patients with polyuria on follow-up were extracted from the records and the hospital information system. An experienced neuroradiologist examined the magnetic resonance imaging (MRI) findings of the pituitary., Results: The mean age of the patients was 43 ± 9 years and 80% were male. Around 90% of patients belonged to upper-lower socioeconomic status according to the modified Kuppuswamy scale. The commonest snake species reported was Russell's viper. Thirteen patients had delayed HP. The median duration from snakebite to onset of HP symptoms was 1 year (range 0.33-10 years). However, the median time from snakebite to the diagnosis of HP was 7 years (range 1-13 years). Central hypothyroidism and hypogonadism were present in all subjects. However, central hypocortisolism was noted in 93% of patients. Low IGF-1 was noted in all the six patients where data were available. One patient had partial central DI. Thirteen out of 15 patients had reduction of pituitary volume in MRI., Conclusion: HP in patients with SE can appear slowly and the diagnosis is frequently delayed for years. Following snakebite, multiple pituitary hormone deficiencies associated with radiological abnormalities like a significant reduction in the pituitary volume are common., Competing Interests: None

In most patients, osteoporosis is diagnosed only after the occurrence of the first fragility fracture. It is of utmost importance to start osteoporosis medications immediately in these patients to prevent future fractures and also to reduce associated mortality and morbidity. There remains a hesitancy over initiating osteoporotic medications, specifically for antiresorptive agents like bisphosphonates following an acute fracture due to concern over their effect on fracture healing. The purpose of this review is to study the effect of the timing of initiation of different osteoporosis medications on healing after an acute fracture. Most of the human studies, including randomized control trials (RCTs), did not find any significant negative effect on fracture healing with early use of bisphosphonate after an acute fracture. Anabolic agents like teriparatide have shown either neutral or beneficial effects on fracture healing and thus can be started very early following any osteoporotic fracture. Although human studies on the early use of other osteoporosis medications like denosumab or strontium ranelate are very sparse in the literature, none of these medications have shown any evidence of delay in fracture healing. To summarize, among the commonly used anti-osteoporosis agents, both bisphosphonates and teriparatide are safe to be initiated in the early acute post-fracture period. Moreover, teriparatide has shown some evidence in favor of reducing fracture healing time., Competing Interests: Competing interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s), 2022.)
