In its wake, the COVID‐19 pandemic has ushered in a surge in the number of cases of mucormycosis. Most cases are temporally linked to COVID‐19; hence, the entity is described as COVID‐19‐associated mucormycosis (CAM). The present systematic review was undertaken to provide an up‐to‐date summary of the hitherto available literature on CAM. PubMed, Scopus and Google Scholar databases were systematically searched using appropriate keywords till 14 May 2021, to identify case reports/case series pertaining to mucormycosis in patients with COVID‐19. Relevant data extracted included demographic characteristics, comorbidity profile, clinical category of mucormycosis, glucocorticoid use, treatment offered and patient outcome. We identified 30 case reports/case series, pooling data retrieved from 99 patients with CAM. Most cases were reported from India (72%). The majority of the patients was male (78%) and had diabetes mellitus (85%). A prior history of COVID‐19 was present in 37% patients with mucormycosis developing after an initial recovery. The median time interval between COVID‐19 diagnosis and the first evidence of mucormycosis infection or CAM diagnosis was 15 days. Glucocorticoid use was reported in 85% of cases. Rhino‐orbital mucormycosis was most common (42%), followed by rhino‐orbito‐cerebral mucormycosis (24%). Pulmonary mucormycosis was observed in 10 patients (10%). The mortality rate was 34%; the use of adjunct surgery, which was undertaken in 81% of patients, was associated with better clinical outcomes (p

Purpose To provide a precise summary and collate the hitherto available clinical evidence on the effect of vitamin D supplementation on clinical outcomes in COVID-19 patients. Methods PubMed/MEDLINE, Scopus, and Web of Science databases were systematically searched using appropriate keywords till June 8, 2021, to identify observational studies and randomized controlled trials (RCTs) reporting adverse clinical outcomes (ICU admission and/or mortality) in COVID-19 patients receiving vitamin D supplementation vs. those not receiving the same. Both prior use and use of vitamin D after COVID-19 diagnosis were considered. Unadjusted/adjusted pooled odds ratio (OR) with 95% confidence intervals (CI) were calculated (PROSPERO registration number CRD42021248488). Results We identified 13 studies (10 observational, 3 RCTs) pooling data retrieved from 2933 COVID-19 patients. Pooled analysis of unadjusted data showed that vitamin D use in COVID-19 was significantly associated with reduced ICU admission/mortality (OR 0.41, 95% CI: 0.20, 0.81, p = 0.01, I2 = 66%, random-effects model). Similarly, on pooling adjusted risk estimates, vitamin D was also found to reduce the risk of adverse outcomes (pooled OR 0.27, 95% CI: 0.08, 0.91, p = 0.03, I2 = 80%, random-effects model). Subgroup analysis showed that vitamin D supplementation was associated with improved clinical outcomes only in patients receiving the drug post-COVID-19 diagnosis and not in those who had received vitamin D before diagnosis. Conclusions Vitamin D supplementation might be associated with improved clinical outcomes, especially when administered after the diagnosis of COVID-19. However, issues regarding the appropriate dose, duration, and mode of administration of vitamin D remain unanswered and need further research.

In this meta-analysis, we analyzed 7 observational studies for assessing the fracture risk in patients with hypoparathyroidism (hypoPT). We found that the risk of vertebral fractures is increased by almost 2-fold, especially those with nonsurgical hypoPT. Patients with hypoPT have higher bone mineral density than age- and sex-matched controls. This would theoretically translate into a lower risk of fractures, although available clinical evidence is contradictory. Hence, the present systematic review and meta-analysis was undertaken to collate and provide a precise summary of fracture risk in hypoPT. PubMed, Scopus, and Web of Science databases were systematically searched using appropriate keywords till March 8, 2021, to identify observational studies reporting the rate of occurrence of fractures among hypoPT patients (nonsurgical and/or postsurgical) compared to non-hypoPT subjects (controls). Study quality was assessed using Newcastle-Ottawa Scale. Pooled odds ratio (OR) with 95% confidence intervals (CI) was calculated. Subgroup analyses of nonsurgical and postsurgical hypoPT patients were also conducted. We identified 7 observational studies of high-quality pooling data retrieved from 1470 patients with hypoPT. When stratified based on the skeletal site, pooled analyses showed that hypoPT patients were at an increased risk of vertebral fractures compared to non-hypoPT controls (OR 2.22, 95% CI: 1.23, 4.03, p = 0.009, I2 = 49%, random-effects model). The increased risk of vertebral fractures was seen only in patients with nonsurgical hypoPT (OR 2.31, 95% CI: 1.32, 4.03, p = 0.003, I2 = 3%, random-effects model) but not in those with postsurgical hypoPT. hypoPT patients were not at an increased or decreased risk of any, humerus, or proximal femur/hip fractures than controls. Nonsurgical hypoPT patients are at an almost 2-fold increased risk of vertebral fractures and thus need to be actively screened irrespective of the underlying BMD.

Background and aims To summarize the available evidence on the use COVID-19 vaccines in patients with diabetes mellitus. Methods We performed a thorough literature search with regard to COVID-19 vaccines in patients with type 1 and type 2 diabetes mellitus. Results The novel coronavirus disease (COVID-19) tends to portend a poor prognosis in patients with diabetes mellitus (DM). Primary prevention remains the mainstay for mitigating the risks associated with COVID-19 in patients with DM. A significant step in primary prevention is timely vaccination. Routine vaccination against pneumococcal pneumonia, influenza, and hepatitis B is recommended in patients with DM with good efficacy and reasonable safety profile. With clinical data supporting a robust neutralizing antibody response in COVID-19 patients with DM, vaccination in individuals with DM is justified. In fact, as the burden of the disease is borne by people with DM, COVID-19 vaccination should be prioritized in individuals with DM. Multiple unresolved issues with regard to preferred vaccine type, vaccine efficacy and durability, frequency of administration, vaccination in children (

Objectives To determine the prevalence of sarcopenia obesity (SO) in healthy Indian adults and delineate the relative impact of the 3 indices of obesity [body mass index (BMI), waist circumference (WC), fat mass percent (FM%)] with regards to inter-definitional agreement and their relationship with usual gait speed (GS). Methods Apparently healthy adults (aged ≥ 20 years) with no background history of comorbidities were enrolled from the community by door-to-door survey. Following blood investigations, individuals with biochemical abnormalities were excluded. Enrolled participants underwent dual-energy X-ray absorptiometry (DXA). Sarcopenia was defined according to EWGSOP2 consensus based on indigenous cut-offs obtained from the Sarcopenia-Chandigarh Urban Bone Epidemiological Study (Sarco-CUBES). Obesity was defined based on BMI (≥ 25.0 kg/m2) or WC (> 90 cm in men, > 80 cm in women) or DXA-derived FM% (> 32% in men, > 40% in women). Results Data of 804 participants were analyzed after exclusion. The mean ± SD for BMI, WC, and FM% were 26.5 ± 2.7 kg/m2, 86.8 ± 9.6, and 34.7 ± 7.3%, respectively. Prevalence of sarcopenia was 3.2%. Based on BMI, WC, and FM%, the prevalence of SO in elderly subjects (≥65 years) was 5.4%, 5.4%, and 6.3%, respectively. Using Cohen’s kappa, inter-definitional agreement between the 3 groups was ‘almost perfect’. FM%, and not BMI/WC, emerged as a significant predictor of GS on multiple linear regression analysis. Conclusions The prevalence of SO in healthy elderly Indian adults is 5.4%–6.3%. Either BMI/WC/FM% can be used to correctly identify individuals with SO.

Background and aims Patients with diabetes mellitus (DM) often demonstrate impaired antibody response to influenza/hepatitis B vaccines. Hence, we compared anti-SARS-CoV-2 antibody response in non-severe COVID-19 patients with and without type 2 diabetes mellitus (T2DM). Methods Records of non-severe COVID-19 patients admitted at our institution between April 10, 2020 and May 20, 2020 were retrieved. Qualitative detection of total (IgG + IgM) anti-SARS-CoV-2 antibody was performed using electrochemiluminescence immunoassay in plasma samples collected at least 14 days post-polymerase chain reaction (PCR) confirmation of diagnosis. Results Thirty-one non-severe COVID-19 patients were included. Nine patients (29%) had T2DM with mean HbA1c at admission of 8.3 ± 1.0%. Anti-SARS-CoV-2 antibody was estimated at a median of 16 (14–17) days post-PCR confirmation of COVID-19 diagnosis. Only three patients (10%) were seronegative, and all had T2DM. Patients with T2DM were more likely to have non-detectable anti-SARS-CoV-2 antibodies than those without DM (p = 0.019). Conclusions COVID-19 patients with T2DM may not undergo seroconversion even after two weeks of diagnosis. Impaired seroconversion could theoretically increase the risk of reinfections in patients with DM. However, the finding requires validation in large-scale studies involving serial estimations of anti-SARS-CoV-2 antibodies in patients with and without DM., Highlights • Non-severe COVID-19 patients with T2DM were more likely to be seronegative for anti-SARS-CoV-2 antibodies. • Seronegative patients had higher HbA1c and longer duration of T2DM than seropositive patients. • Absence of anti-SARS-CoV-2 antibodies might increase the risk of reinfections in patients with T2DM.

Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological entity characterized by subcortical vasogenic edema presenting with acute neurological symptoms. Common precipitating causes include renal failure, pre-eclampsia/eclampsia, post-organ transplant, and cytotoxic drugs. Hypercalcemia is a rare cause of PRES; most cases occur in the setting of severe hypercalcemia secondary to malignancy or iatrogenic vitamin D/calcium overdose. Primary hyperparathyroidism (PHPT), as a cause of PRES, is an oddity. We report two cases of adolescent PHPT presenting with generalized tonic-clonic seizures and altered sensorium. On evaluation, both had hypertension, severe hypercalcemia (serum calcium 14.1 mg/dL and 14.5 mg/dL, respectively) and elevated parathyroid hormone levels. Magnetic resonance imaging (MRI) revealed T2/fluid-attenuated inversion recovery hyperintensities located predominantly in the parieto-occipital regions, suggestive of PRES. Identification and excision of parathyroid adenoma led to the restoration of normocalcemia. Neurological symptoms and MRI changes improved subsequently. An extensive literature search revealed only four cases of PHPTassociated PRES; none of them being in the pediatric/adolescent age group. The predominant clinical manifestations were seizures and altered sensorium. All had severe hypercalcemia; three had hypertension at presentation, while one was normotensive. Parathyroid adenomectomy led to normalization of serum calcium and resolution of neurological symptoms and radiological changes. Thus, severe hypercalcemia, although rare in PHPT, can lead to hypercalcemic crisis precipitating acute hypertension that can result in cerebral endothelial dysfunction with the breakdown of the blood-brain barrier, culminating in PRES. We therefore recommend that serum calcium levels should be checked in all patients with PRES and that PHPT be regarded as a differential diagnosis in those with underlying hypercalcemia.

To present the data on primary hyperparathyroidism (PHPT) in pregnancy from India obtained from a large database maintained over 15 years. We retrieved data of all women with gestational PHPT from the Indian PHPT registry between July 2005 and January 2020, and compared their clinical, biochemical, and other characteristics with age-matched non-pregnant women with PHPT. Out of 386 women, eight had gestational PHPT (2.1%). The common presenting manifestations were acute pancreatitis (50%) and renal stone disease (50%); two were asymptomatic. Five women (62.5%) had a history of prior miscarriages. Seven patients (88%) had preeclampsia during the present gestation. Serum calcium and intact parathyroid hormone (iPTH) were not statistically different from the age-matched non-pregnant PHPT group. Six patients with mild-to-moderate hypercalcemia were medically managed with hydration with/without cinacalcet while one patient underwent percutaneous ethanol ablation of the parathyroid adenoma; none underwent surgery during pregnancy. Mean serum calcium maintained from treatment initiation till delivery was 10.5 ± 0.4 mg/dl. One patient had spontaneous preterm delivery at 36 weeks; the remaining patients had normal vaginal delivery at term. None had severe preeclampsia/eclampsia. Fetal outcomes included low birth weight in three newborns (37.5%); two of them had hypocalcemic seizures. The prevalence of gestational PHPT was 2.1% in this largest Indian PHPT cohort, which is higher than that reported from the West (

Context Preliminary data on coexistence of secondary hemophagocytic lymphohistiocytosis syndrome (HLH) and disseminated intravascular coagulation (DIC) in critically ill children with novel coronavirus disease (COVID-19) are emerging. Herein, we summarize the available literature and fill-in the gaps in this regard. Evidence Acquisition We have performed a literature search for articles in PubMed, EMBASE and Google Scholar databases till May 12, 2020, with following keywords: “COVID-19”, “SARS-CoV-2”, “HLH”, “HScore”, “coagulopathy”, “D-dimer”, “cytokine storm”, “children” and “pediatrics” with interposition of Boolean operator “AND”. Results Children presenting with moderate-severe COVID-19 and Kawasaki disease shock-like syndrome exhibit peripheral blood picture analogous to HLH. HScore, a validated tool to diagnose HLH, has been suggested to screen severe COVID-19 patients for cytokine storm. However, HScore faces certain limitations in this scenario. It may be more pragmatic to use ‘high D-dimer’ (> 3 µg/mL) instead of ‘low fibrinogen’ to facilitate early detection of cytokine storm. COVID-19 associated coagulopathy resembles hypercoagulable form of DIC with bleeding being rarely reported. Although the International Society on Thrombosis and Haemostasis (ISTH) interim guidance recommends low molecular weight heparin in all hospitalized patients, data is lacking in population below 14 years of age. However, in the presence of life-threatening thromboembolic event or symptomatic acro-ischemia, unfractionated heparin (UFH) should be used with caution. Conclusions HScore can be used as a complement to clinical decision for initiating immunosuppression. Children with moderate-to-severe COVID-19, especially those with documented thrombocytopenia or chilblains, should be regularly monitored for coagulopathy.

Background and aims COVID-19 pandemic has challenged the physician-centered approach of diabetes care in India that is primarily based on routine clinic visits. We aim to review the various aspects of patient-centered care via diabetes self-management education based on available literature. Methods This is a narrative review using Pubmed, EMBASE and Google Scholar search till March 29, 2020. Search terms were “COVID-19”, “diabetes self-care”, “diabetes self-management education”, “DSME”, “diabetes self-management in India”, “diabetes self-care in India” and “DSME in India”. Results We have discussed an educational plan on diabetes self-management that can be adopted for people with diabetes mellitus in our country amid the ongoing pandemic. We have also identified the barriers to diabetes self-management in the current scenario and suggested possible solutions to overcome those. Conclusions We have reemphasized the need for a simultaneous patient-centered approach in routine diabetes care that has to be coordinated by a multidisciplinary team amid the ongoing COVID-19 pandemic., Highlights • Simultaneous patient-centered approach via diabetes self-management education (DSME) is essential in routine diabetes care. • During pandemic, DSME should focus on diet, exercise, medication adherence, hypoglycemia prevention and healthy coping. • Multidisciplinary team based DSME system can overcome the current barriers amid COVID-19 pandemic.

To determine the diagnostic cut-offs and the prevalence of sarcopenia in India. Indians have lower muscle strength and muscle mass than Caucasians. The prevalence of ‘probable sarcopenia’, ‘sarcopenia’, and ‘severe sarcopenia’ is 14.6%, 3.2%, and 2.3%, respectively; corresponding values are higher using well-established Western cut-offs. Indigenous and not Western cut-offs should be used to define sarcopenia in Indians. Comprehensive data on diagnosis and prevalence of sarcopenia in India are lacking. The present study was undertaken to determine cut-offs for low muscle strength (MS) and low muscle mass (MM), and find out the prevalence of sarcopenia in Indians. Apparently healthy individuals aged ≥ 20 years with no prior history of any co-morbidities were recruited from community by door-to-door survey. Participants eligible for study underwent blood sampling. Individuals identified as having biochemical abnormalities that could potentially affect MS and MM were excluded. Enrolled participants underwent DEXA. Muscle mass, MS, and physical performance were expressed as appendicular skeletal muscle index (ASMI), dominant handgrip strength (HGS), and usual gait speed (GS), respectively. Cut-offs for low MS and MM were defined as HGS and ASMI 2SD

BACKGROUND Primary hyperparathyroidism (PHPT) results in reduction of bone mineral density (BMD) and an increased risk of pathological fractures. Curative surgery does improve BMD; however, the magnitude of rise and predictive factors are highly variable amongst the hitherto available studies. OBJECTIVES To quantify the magnitude of improvement in BMD after curative surgery in patients with symptomatic PHPT and dissect out the possible clinical and biochemical parameters predicting the BMD rise. METHODS We conducted a retrospective study of symptomatic PHPT patients undergoing surgery between August 2016 and July 2018. Patients achieving biochemical cure with pre- and post-operative (at least 1 year after surgery) dual-energy X-ray absorptiometry scans performed were included in the study. RESULTS After exclusion, 63 patients were included in the study (M:F = 2:5; mean age = 44.8 years). At a median interval of 15 months, the median per cent change in BMD (ΔBMD) at lumbar spine (LS), total hip (TH), femoral neck (FN) and one-third distal radius (forearm) was 6.5%, 7.0%, 8.1% and 6.9%, respectively. Following multiple linear regression analysis, baseline BMD was found to inversely predict ΔBMD at LS, TH and forearm. Pre-operative iPTH positively predicted ΔBMD at LS and FN. Interestingly, 82.5% of the patients had a gain in body weight following curative surgery and change in body weight emerged as a significant positive predictor of ΔBMD at all sites. CONCLUSIONS Curative surgery improves BMD at all sites in patients with symptomatic PHPT. Weight gain following surgery can be used as a positive clinical predictor of BMD rise.

Background Craniopharyngiomas are sellar–suprasellar tumors that commonly present in children, with nonspecific symptoms of increased intracranial pressure, visual disturbances, and pituitary insufficiencies. Rarely has secondary hypophysitis (lymphocytic and xanthogranulomatous) been reported in association with craniopharyngioma. Case Description We have reported the case of a 16-year-old boy who had presented with gradually progressive diminution of vision in the right eye, intermittent headache, deceleration in growth velocity, and the lack of development of secondary sexual characteristics. Imaging revealed a sellar–suprasellar cystic lesion (3.8 × 3.1 × 3.5 cm) with calcifications. Laboratory tests revealed hypothyroidism, hypocortisolism, hypogonadism, and growth hormone deficiency. Craniopharyngioma was provisionally diagnosed. He underwent pterional craniotomy and gross total excision of the lesion. The excised tissue showed features of adamantinomatous craniopharyngioma, with a dense lymphoplasmacytic infiltrate and fibrosis involving the pituitary and dura mater. The lymphocytes were CD20-positive, and the plasma cells stained positive for IgG4 (50–60 IgG4-positive plasma cells/high power field). Consequently, the possibility of IgG4-related hypophysitis was considered in our patient. His serum IgG4 level was not elevated. Systemic involvement by IgG4-related disease was thoroughly ruled out. Fluorodeoxyglucose positron emission tomography/computed tomography did not show any clinically significant hypermetabolism anywhere in the body. At the 3-month follow-up examination, his headache had resolved. However, he had not regained vision in his right eye. Repeat imaging studies showed no residual tumor tissue. Conclusions The present case might represent the first ever report, to the best of our knowledge, of secondary IgG4-related hypophysitis due to craniopharyngioma, or it might, perhaps, be a chance association of these 2 entirely different disease entities.

Patients with type 2 diabetes mellitus (T2DM) have an increased risk of hip and vertebral fractures. The increased fracture risk has largely been attributed to poor bone quality and microarchitecture. The contribution of bone quantity, measured as areal bone mineral density (BMD), to the risk of fracture is variable with most studies showing an increase in BMD in T2DM. The present study was undertaken to find out the prevalence of osteoporosis and osteopenia (based on BMD) in a cohort of patients with T2DM and delineate the possible modifiable and non-modifiable risk factors. In this cross-sectional observational study, 252 otherwise ostensibly healthy patients with T2DM underwent dual energy X-ray absorptiometry (DEXA) scan. Osteoporosis and osteopenia were defined based on T-scores. The effect of modifiable and non-modifiable risk factors on BMD and osteoporosis were assessed. The mean age of the cohort was 59.9 years with a M:F ratio 2.9:3.4. The mean BMD at the lumbar spine and hip were 0.892 g/cm2 and 0.715 g/cm2, respectively. Males had significantly higher BMD at both the sites compared to females. The prevalence of osteoporosis and osteopenia was 33% and 40%, respectively. Female gender, increasing age, normal body mass index (BMI), low serum 25-hydroxyvitamin D, and use of pioglitazone were significantly associated with the risk of osteoporosis. The prevalence of osteoporosis and osteopenia in patients with T2DM is high. Female gender, increasing age, normal BMI, low serum 25-hydroxyvitamin D, and pioglitazone use further increase the risk of osteoporosis.

Pendular see-saw nystagmus is an extremely rare form of nystagmus characterised by cyclical movement of the eyes with a conjugate torsional component and a disjunctive vertical component. Intorsion and elevation of one eye is accompanied by simultaneous extorsion and depression of the contralateral eye. Most commonly it results from a suprasellar/parasellar mass compressing the meso-diencephalic region. Herein, we report a case of a 5-year-old girl who presented with pendular see-saw nystagmus secondary to a craniopharyngioma. The nystagmus resolved following excision of the lesion.

We aimed to estimate metabolic bone profile in a large cohort of healthy, adult Indian population to generate reference standards of serum calcium, phosphate and alkaline phosphatase (ALP), 25 (OH) Vitamin D and iPTH, and also to find out the prevalence of Vitamin D deficiency in healthy population. Apparently healthy people in the age group of 20–80 years, residing in the union territory of Chandigarh were chosen. Fasting samples for serum calcium, phosphate, albumin, alkaline phosphatase (ALP), 25 (OH) D and iPTH were collected and were processed on the same day. We recruited 930 healthy subjects from different subsectors of Chandigarh. Final analysis was done for 915 subjects. Out of this, 530 (58%) were women and 385 (42%) were men. The study participants were divided into two groups, less than and more than 50 years for the men and pre and post-menopausal for the women. The serum calcium, phosphate, ALP and iPTH were significantly higher in the post-menopausal women compared to the pre-menopausal women. The median plasma 25 (OH) D in men and women was 12.5 ng/mL and 14.3 ng/mL, respectively. 25 (OH) D deficiency was seen in 65.4% of individuals. 25 (OH) D levels co-related negatively with iPTH levels (r = − 0.4, p

The novel coronavirus disease (COVID-19) is on the rampage claiming over 297000 lives globally. Disease severity and mortality rates are higher in patients with underlying diabetes mellitus. Till date, there exists no effective vaccine or therapy against COVID-19. However, with limited clinical data, HCQ is being used for treatment and prophylaxis in patients with COVID-19. HCQ is also used as an anti-diabetic drug and has been approved in India as an adjunct to diet and exercise to improve glycemic control of patients with Type 2 Diabetes Mellitus (T2DM) on metformin and sulfonylurea combination in Type 2 Diabetes Mellitus (T2DM). Thus, although indiscriminate use of HCQ is fraught with danger, HCQ can be considered as a third-line add on anti-diabetic agent in people with T2DM amid the ongoing pandemic after having ruled out the contraindications to the use of this drug.

The Indian Society for Bone and Mineral Research (ISBMR) has herein drafted clinical practice guidelines for the diagnosis and management of osteoporosis for the people of India. Implementation of the position statement in clinical practice is expected to improve the overall care of patients with osteoporosis in India. In India, osteoporosis is a major public health problem. However, in the absence of any robust regional guidelines, the screening, treatment, and follow-up of patients with osteoporosis are lagging behind in the country. The Indian Society for Bone and Mineral Research (ISBMR), which is a multidisciplinary group of physicians, researchers, dietitians, and epidemiologists and who study bone and related tissues, in their annual meeting, drafted the guidelines for the diagnosis and management of osteoporosis that would be appropriate in a resource constraint setting like India. Diagnosis of osteoporosis can be made in a patient with minimal trauma fracture without the aid of any other diagnostic tools. In others, bone mineral density measured by dual-energy X-ray absorptiometry remains the modality of choice. Data indicates that osteoporotic fractures occur at an earlier age in Indians than in the West; hence, screening for osteoporosis should begin at an earlier age. FRAX can be used for fracture risk estimation; however, it may underestimate the risk of future fractures in our population and still needs validation. Maintaining optimum serum 25-hydroxyvitamin D levels is essential, which, in most cases, would require regular vitamin D supplementation. Pharmacotherapy should be guided by the presence/absence of vertebral/hip fractures or the severity of risk based on clinical factors, although bisphosphonates remain the first choice in most cases. Regular follow-up is essential to ensure adherence and response to therapy. Implementation of the position statement in clinical practice is expected to improve the overall care of patients with osteoporosis in India.

Objective To describe the prevalence and compare the clinicobiochemical profile of patients with primary hyperparathyroidism (PHPT) with and without type 2 diabetes mellitus (T2DM). Methods We conducted a retrospective observational study wherein the details of patients with PHPT with T2DM (PHPT-T2DM) and without T2DM were retrieved from the Indian PHPT Registry ( www.indianphptregistry.com ) between 2005 and 2019. We compared the clinical, biochemical, and postoperative findings of patients with PHPT-T2DM with age-, sex-, and body mass index–matched patients with PHPT without T2DM (in 1:2 ratio). Results Of the 464 patients with PHPT, 54 (11.6%) had T2DM. We observed an increase in the prevalence of PHPT-T2DM cases over time; only 7 (7.1%) of the total patients with PHPT had T2DM between 2005 and 2009 that increased to 31 (12.8%) in the last half decade (2015-2019). Patients with PHPT-T2DM had a significantly lower prevalence of nephrolithiasis (18.5% vs 36.1%, respectively; P = .03) and a higher prevalence of pancreatitis (22.2% vs 5.6%, respectively; P = .007) than those without T2DM. Furthermore, intact parathyroid hormone (203 pg/mL [139.8-437.3 pg/mL] vs 285 pg/mL [166-692 pg/mL], respectively; P = .04) and serum creatinine (0.90 mg/dL [0.67-1.25 mg/dL] vs 1.10 mg/dL [0.73-1.68 mg/dL], respectively; P = .03) levels were significantly lower in patients with PHPT-T2DM than those without T2DM. Also, tumor weight tended to be lower in patients with PHPT-T2DM than in the non-T2DM counterparts (1.05 g [0.5-2.93 g] vs 2.16 g [0.81-7.0 g], respectively; P = .06). Conclusion The prevalence of T2DM in Asian Indians with PHPT is 11.6%. Patients with PHPT-T2DM are characterized by a higher prevalence of pancreatitis, a lower prevalence of nephrolithiasis, and lower levels of intact parathyroid hormone/creatinine. Part of the clinical picture can possibly be explained by early detection of PHPT in patients with T2DM consequent to more frequent screening.

The second wave of the COVID-19 pandemic has hit India hard. The number of new cases per day has gone up from 11 794 in the first week of February 2021 to over 414 000 as of 6 May 2021. The number of new deaths per day has shot up from 116 in the first week of February 2021 to more than 4500 as of 18 May 2021. Test positivity rates rose nationwide from 2.8% in the first week of April 2021 to 22% in the first week of May. The second wave is different from the first wave that occurred in September 2020 in a few ways. First, the rate of increase in new cases is significantly higher. Second, a marginal rise has been recorded in the number of young people testing positive for the virus than the first wave. Third, compared with the first wave, there has been a substantial increase in the proportion of patients presenting with shortness of breath and those requiring oxygen supplementation and mechanical ventilation during the ongoing second wave. The sudden avalanche of severe COVID-19 cases has expectedly led to an acute shortage of hospital beds, oxygen and medications. Finally, unlike the first wave, a significant proportion of the cases in the second wave are being caused by SARS-CoV-2 variants, which are believed to be more …

PURPOSE OF REVIEW Despite estimated 77 million people having diabetes, bone health in Asian Indians with diabetes is largely unknown. This review summarizes the published literature on fracture risk and factors affecting it in Asian Indians with diabetes. RECENT FINDINGS Data on fracture prevalence in diabetes is limited; one study showed that diabetes was associated with a significantly higher number of fractures compared with subjects without diabetes (4% vs. 2.4%, P

Primary hyperparathyroidism (PHPT) is a rare endocrine disease in the pediatric population. Sporadic parathyroid adenomas remain the most common cause of pediatric PHPT. Parathyroid carcinoma (PC) is an extremely rare cause of pediatric PHPT. We report a 16-year-old boy presenting with a nonhealing fragility fracture of the right leg along with florid features of rickets. Examination revealed a neck mass, mimicking a goiter. Biochemical findings were consistent with PHPT. Imaging was suggestive of a right inferior parathyroid mass infiltrating the right lobe of thyroid. The patient underwent en bloc surgical excision of the parathyroid mass along with the right lobe of thyroid. Histopathology was suggestive of a PC. He achieved biochemical remission with normalization of serum calcium and parathyroid hormone levels. At follow-up, there was no biochemical or imaging evidence of recurrence or metastasis. Genetic analysis revealed heterozygous germline deletion of CDC73. An extensive literature search on PC was conducted, with an emphasis on the pediatric population. Thirteen cases of pediatric PC were identified. The median age of presentation was 13 years; there was no sex predilection. All cases were symptomatic; 31% had a visible neck mass. The median serum calcium and intact parathyroid hormone levels were 14.3 mg/dL and 2000 pg/mL, respectively. All patients underwent surgical excision, with 27% showing metastatic relapse. Our findings indicate that the preoperative features that could point toward a diagnosis of PC in a child with PHPT are a tumor size of >3 cm, thyroid infiltration on imaging, and severe hypercalcemia at presentation.

Germinomas are highly immunogenic tumors eliciting a strong peri-tumoral immune response that can spillover into the surrounding healthy tissues. This phenomenon can also occur in intracranial germinomas, manifesting as secondary hypophysitis. Herein, we report a case of 12-year-old-girl presenting with polyuria and polydispsia. She had central diabetes insipidus (CDI) and panhypopituitarism. Imaging revealed a sellar-suprasellar mass with infundibular stalk thickening. Transphenoidal biopsy revealed epithelioid granulomas with immunostaining negative for germinomatous cells. Other causes of hypophysitis were ruled out. Accordingly, she was diagnosed as primary granulomatous hypophysitis and treated with high-dose corticosteroids. Three years later she again presented with headache, vomiting and diminution of vision. Imaging showed a heterogeneous, solid-cystic peripheral rim-enhancing lesion at the same location with involvement of hypothalamus, ependyma and pineal gland. Cerebrospinal fluid beta-human chorionic gonadotropin was markedly elevated, confirming the diagnosis of an intracranial germ cell tumor. She was started on chemotherapy; however, she succumbed to febrile neutropenia. We performed a literature search and found 18 anecdotal cases of secondary hypophysitis associated with intracranial germinomas. There was a slight male preponderance (male:female 5:4). Two-thirds of the cases were below 18 years of age. Polyuria was the most common presenting manifestation (83%). CDI and panhypopituitarism were seen in 89 and 78% cases, respectively. Imaging evidence of pituitary stalk thickening was seen in 12 cases (67%), while pituitary enlargement and/or sellar mass were reported in 11 cases (61%). Pineal involvement was extremely rare, being reported in only 1 case, implying the predilection of suprasellar (rather than pineal) germinomas in causing secondary hypophysitis. Histologically, 82% had lymphocytic hypophysitis, while 18% had granulomatous hypophysitis. Initially, the diagnosis of germinoma was missed in 60% of the cases who were wrongly treated with corticosteroids. To conclude, physicians should make it a dictum that all children and adolescents presenting with CDI and pituitary stalk thickening should be rigorously screened for an underlying intracranial germinoma before labeling them as primary hypophysitis.

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome characterized by recalcitrant hypophosphatemia. Reports from the Indian subcontinent are scarce, with most being single center experiences involving few patients. Herein, we conducted a retrospective analysis of 30 patients of TIO diagnosed at three tertiary care hospitals in India. Patients with persistent hypophosphatemia (despite correction of hypovitaminosis D), normocalcemia, elevated alkaline phosphatase, low TmP/GFR and elevated or ‘inappropriately normal’ FGF23 levels were labeled as having TIO. They were sequentially subjected to functional followed by anatomical imaging. Patients with a well-localized tumor underwent excision; others were put on phosphorous and calcitriol supplementation. The mean age at presentation was 39.6 years with female:male ratio of 3:2. Bone pain (83.3%) and proximal myopathy (70%) were the chief complaints; 40% of cases had fractures. The mean delay in diagnosis was 3.8 years. Tumors were clinically detectable in four patients (13.3%). The mean serum phosphate was 0.50 mmol/L with a median serum FGF23 level of 518 RU/mL. Somatostatin receptor-based scintigraphy was found to be superior to FDG-PET in tumor localization. Lower extremities were the most common site of the tumor (72%). Tumor size was positively correlated with serum FGF23 levels. Twenty-two patients underwent tumor resection and 16 of them had phosphaturic mesenchymal tumors. Surgical excision led to cure in 72.7% of patients whereas disease persistence and disease recurrence were seen in 18.2% and 9.1% of cases, respectively. At the last follow-up, serum phosphate in the surgically treated group was significantly higher than in the medically managed group.

Background Phosphaturic mesenchymal tumor-mixed connective tissue (PMT-MCT) is a rare tumor characterized clinically by presence of tumor-induced osteomalacia (TIO), subsequent to elevated fibroblastic growth factor 23 (FGF23) levels. This study aims to analyse the morphological spectrum of PMT along with clinico-pathological correlation and immunophenotype profile of this rare tumor. Materials and methods Detailed histological analysis of all tumors presenting with TIO over past 7 years was done retrospectively. Immunohistochemistry was performed in all cases for SATB2, STAT6, CD34, FGF23, ERG, S100 and smooth muscle actin (SMA). Results A total of 13 cases were analysed (8 female and 5 male) with mean age of 39.8 years. Five cases were arising from bone while 4 each from soft tissue and nasal cavity/paranasal sinus. All presented with hypophosphatemia, hyperphosphaturia, elevated serum FGF23 and features suggestive of osteomalacia. Histological examination revealed basophilic ‘grungy’ calcification seen in 7 (53.8%), osteoid formation in 8 (61.5%), chondroid matrix in 4 (30.8%), adipose tissue in 6 (46.2%), osteoclast-like giant cells in 9 (69.2%) and hemangiopericytomatous (HPC like) blood vessels in 7 cases (53.8%). HPC like vessels and adipose tissue were more common in nasal tumors while calcification was more common in tumors arising from bone. All cases showed immunoreactivity for SATB2 and clinical improvement following resection except one case with residual tumor. Conclusion PMT shows varied histological pattern with various matrix components depending on the site of the tumor. Serum FGF-23 is a useful adjunctive marker for diagnosis.

Purpose Observations studies have shown that prior use of statins is associated with a reduced risk of adverse clinical outcomes in patients with COVID-19. However, the available data are limited, inconsistent and conflicting. Besides, no randomised controlled trial exists in this regard. Hence, the present meta-analysis was conducted to provide an updated summary and collate the effect of statin use on clinical outcomes in COVID-19 using unadjusted and adjusted risk estimates. Methods PubMed, Scopus and Web of Science databases were systematically searched using appropriate keywords till December 18 2020, to identify observational studies reporting clinical outcomes in COVID-19 patients using statins versus those not using statins. Prior and in-hospital use of statins were considered. Study quality was assessed using the Newcastle-Ottawa Scale. Unadjusted and adjusted pooled odds ratio (OR) with 95% CIs were calculated. Results We included 14 observational studies pooling data retrieved from 19 988 patients with COVID-19. All the studies were of high/moderate quality. Pooled analysis of unadjusted data showed that statin use was not associated with improved clinical outcomes (OR 1.02; 95% CI 0.69 to 1.50, p=0.94, I2=94%, random-effects model). However, on pooling adjusted risk estimates, the use of statin was found to significantly reduce the risk of adverse outcomes (OR 0.51; 95% CI 0.41 to 0.63, p Conclusions Statin use is associated with improved clinical outcomes in patients with COVID-19. Individuals with multiple comorbidities on statin therapy should be encouraged to continue the drug amid the ongoing pandemic.

AIMS To summarize all relevant randomized controlled trials (RCTs) and provide precise effect estimates of glycaemic efficacy/safety of faster-acting insulin aspart administered by injection as compared to insulin aspart in people with diabetes mellitus. METHODS PubMed/Cochrane Library were systematically searched till October 10, 2020, to identify RCTs with duration ≥16 weeks, evaluating efficacy/safety of mealtime injections of faster aspart compared to insulin aspart in people with type 1 diabetes mellitus and type 2 diabetes mellitus. Studies using faster aspart as continuous subcutaneous insulin infusion were excluded. Continuous and dichotomous outcome variables (expressed as estimated treatment difference and rate ratio in RCTs, respectively) were pooled using generic inverse variance method with fixed/random-effects model. For each outcome variable, subgroup analysis between type 1 diabetes mellitus and type 2 diabetes mellitus was performed. RESULTS We included five RCTs; three of type 1 diabetes mellitus (n = 1963) and two of type 2 diabetes mellitus (n = 1780). All had low risk of bias. Faster aspart was associated with small but significant improvement in HbA1c than insulin aspart (MD: -0.06%, 95% CI: -0.10, -0.02, p = 0.005, I2 = 19%). HbA1c reduction was statistically significant only in type 1 diabetes mellitus on subgroup analysis (MD: -0.08%, 95% CI: -0.14, -0.02, p = 0.005, I2 = 47%). Besides, faster aspart was associated with reduced postprandial plasma glucose (PPG) increment at 1 h/2 h after meal test and increased 1,5-anhydroglucitol compared to insulin aspart. Early postprandial hypoglycaemic episodes were higher with faster aspart; however, overall and nocturnal hypoglycaemic episodes were not different from insulin aspart. CONCLUSIONS Faster aspart is associated with reduced HbA1c , PPG increment and comparable overall hypoglycaemic episodes with regard to insulin aspart.

Purpose: To compare serum total calcium and phosphate levels in patients with non-severe COVID-19 with age, sex, and serum 25-hydroxyvitamin D level matched healthy adult cohort.Methods: In this retrospective case-control study, medical records of patients (≥18 years) diagnosed as non-severe COVID-19 admitted at and discharged from our tertiary care institution during the period from April 10, 2020 and June 20, 2020 were retrieved. Baseline investigations, notably, serum calcium, phosphate, albumin, magnesium, 25-hydroxyvitamin D, and C-reactive protein (CRP), were performed at admission before any form of calcium or vitamin D supplementation were considered. The biochemical parameters were compared with age, sex, and 25-hydroxyvitamin D matched healthy adult controls (1:1 ratio) derived from the Chandigarh Urban Bone Epidemiological Study (CUBES).Results: After exclusion, 72 patients with non-severe COVID-19 (63 mild and 9 moderate disease) and an equal number of healthy controls were included in the final analysis. Age, sex, serum 25-hydroxyvitamin D, and albumin levels were matched between the 2 groups. Hypovitaminosis D and hypocalcemia were seen in 97 and 67% of the patients, respectively. The patients had lower serum calcium (P value P = 0.007) compared with the controls. There was no statistically significant correlation between serum calcium and CRP.Conclusions: Hypocalcemia is highly prevalent even in COVID-19 patients with non-severe disease probably implying that hypocalcemia is intrinsic to the disease. Prospective studies with larger number of patients are required to prove this hypothesis and unravel the underlying pathophysiological mechanisms.

Similar to the SARS-CoV experience,1 a possible link between ABO blood groups with COVID-19 susceptibility and severity has been shown in multiple observational studies.2–4 Gerard et al 5 have further noted that people with B and/or O blood groups were less represented among COVID-19 patients, thereby highlighting the possible beneficial role of anti-A antibodies in COVID-19 susceptibility. In fact, it was known that anti-A antibodies can block the adhesion of SARS-CoV S-protein to ACE2 expressing cell lines.6 Given the genomic similarity between SARS-CoV-2 and SARS-CoV, it might be prudent to hypothesise a protective role of anti-A antibodies against COVID-19 severity as well. However, existing clinical evidence in this regard is controversial. Hoiland et al 7 had reported that critically ill COVID-19 patients with blood groups A and AB (lacking anti-A antibodies) were more likely to require mechanical ventilation and prolonged intensive care compared with patients with B/O (with anti-A antibodies). However, a genomewide association study of severe COVID-19 patients showed that those with blood group A had a higher risk of severe disease, while blood group O had a protective effect.8 Other studies found no association between ABO blood groups and COVID-19 severity/mortality.9–12 We aimed to summarise the available literature and provide a pooled analysis of the effect of A/AB (without anti-A antibodies) on clinical …

Dear Editor,Hungry bone syndrome (HBS) is a clinico-biochemical entity characterized by the development of profound and prolonged hypocalcemia associated with hypophosphatemia, hypomagnesemia, and rising alkaline phosphatase which follows curative parathyroidectomy for severe primary and secondary hyperparathyroidism. The prevalence of HBS after parathyroidectomy in primary hyperparathyroidism (PHPT) is variable with several case series from Asia reporting remarkably higher prevalence rates of 24–87% 1.

Background: Attendants of in-hospital patients are prone to undue stress resulting in depression, anxiety, melancholy and psychological distress. Hitherto available studies cater to attendants of patients admitted in critical care units and none have ventured to look into their cortisol dynamics. Herein, we have evaluated the magnitude of psychological distress and depression amongst ostensibly healthy attendants of non-critically ill patients and correlated them with cortisol dynamics. Methods: Non-critically ill patients admitted to the general medicine ward were chosen by purposive sampling and one attendant was selected from each patient. Those with known risk factors, psychiatric illnesses, chronic drug intake, addictions, and overweight/obesity were excluded. Psychological distress and depression were assessed using the General Health Questionnaire 12-items (GHQ-12) and the Patient Health Questionnaire (PHQ-9), respectively. Morning plasma cortisol, late-night plasma cortisol (LNPC), late-night salivary cortisol (LNSC), urinary free cortisol (UFC), and plasma cortisol after overnight 1 mg dexamethasone administration were measured. Results: After exclusion, 39 participants were recruited (M:F=2.3:1.6). The mean age was 34.1±11.4 years. The mean duration of stay in hospital ambience prior to recruitment was 16.2±1.2 days. Based on the PHQ-9 score, 55% of the participants had depression. Psychological distress prevailed in 13% of participants as per the GHQ-12 score. The median LNPC/LNSC was higher in participants with depression compared to those with no depression, however, there was no statistically significant difference. There was no significant correlation between GHQ-12/PHQ-9 scores and cortisol dynamics. Conclusions: Although depression is prevalent in about half of the patient attendants, cortisol dynamics remain largely unaltered over a short period of two to three weeks.

Background and aim To conduct a systematic literature review and analyze the demographic/biochemical parameters and clinical outcomes of COVID-19 patients with diabetic ketoacidosis (DKA) and combined DKA/HHS (hyperglycemic hyperosmolar syndrome). Methods PubMed, Scopus, Embase, and Google Scholar databases were systematically searched till August 3, 2020 to identify studies reporting COVID-19 patients with DKA and combined DKA/HHS. A total of 19 articles reporting 110 patients met the eligibility criteria. Results Of the 110 patients, 91 (83%) patients had isolated DKA while 19 (17%) had DKA/HHS. The majority of the patients were male (63%) and belonged to black ethnicity (36%). The median age at presentation ranged from 45.5 to 59.0 years. Most of the patients (77%) had pre-existing type 2 diabetes mellitus. Only 10% of the patients had newly diagnosed diabetes mellitus. The median blood glucose at presentation ranged from 486.0 to 568.5 mg/dl, being higher in patients with DKA/HHS compared to isolated DKA. The volume of fluid replaced in the first 24 h was higher in patients with DKA/HHS in contrast to patients with DKA alone. The in-hospital mortality rate was 45%, with higher mortality in the DKA/HHS group than in the isolated DKA group (67% vs. 29%). pH was lower in patients who had died compared to those who were discharged. Conclusion DKA in COVID-19 patients portends a poor prognosis with a mortality rate approaching 50%. Differentiating isolated DKA from combined DKA/HHS is essential as the latter represents nearly one-fifth of the DKA cases and tends to have higher mortality than DKA alone., Highlights • Occasional reports of diabetic ketoacidosis (DKA) have been reported in COVID-19. • DKA is more common in males and in individuals with black ethnicity and pre-existing T2DM. • DKA in COVID-19 portends a poor prognosis with mortality being higher in patients with combined DKA/HHS than isolated DKA.

Antiphospholipid antibodies (APAs) are found quite frequently in patients with non-Hodgkin's lymphoma (NHL). However, the clinical significance of these antibodies is largely unknown. This study aims to delineate the clinical and prognostic role of APAs in NHL patients. Consecutive patients of NHL were screened for lupus anticoagulant (LA), IgG/IgM anticardiolipin antibody, and IgG/IgM anti-β2-glycoprotein I at the time of diagnosis. Baseline investigations, staging, and treatment were done as per institutional protocol. Patients were followed up until the last known outpatient visit or death. All were screened at each visit for any thromboembolic event. The association of APA status with baseline NHL characteristics and treatment response was evaluated by univariate analysis. Kaplan-Meier survival analysis was used to compare the final outcome in patients with or without APAs. Patients who were initially APA positive were retested for the corresponding antibody at the end of chemotherapy. Twenty-four out of 105 patients (22.8%) were APA positive at diagnosis. The presence of APA was not significantly associated with NHL stage, histology, International Prognostic Index score, activated partial thromboplastin time, or treatment response. The median duration of follow-up was 15 months. Only four patients developed venous thrombosis; none was APA positive. There was no statistically significant difference in overall survival between the two groups ( APAs are encountered more frequently in NHL patients than in the general population. However, APAs do not correlate with disease severity, thrombosis risk, treatment outcome, or overall survival.Antiphospholipid-Antikörper (APAs) treten häufig bei Non-Hodgkin-Lymphom-Patienten (NHL) auf, ihre genaue Rolle ist jedoch unklar. Wir verfolgten prospektiv 105 NHL-Patienten über eine mittlere Dauer von 15 Monaten. Antiphospholipid-Antikörper wurden bei 22,8% der NHL-Patienten nachgewiesen, eine Prävalenzrate, die viel höher ist als die der Allgemeinbevölkerung. Neunzehn (79%) waren positiv für einen einzelnen Antikörper, während fünf (21%) positiv für zwei Antikörper waren. Anti-β2-Glykoprotein I war das am häufigsten nachgewiesene APA, gefolgt von Lupus-Antikoagulans und Anti-Cardiolipin-Antikörper. Die mittlere aktivierte partielle Thromboplastinzeit unterschied sich nicht zwischen den APA-positiven und den APA-negativen Gruppen. Nur 4 Patienten (3,8%) hatten eine Venenthrombose entwickelt; Keiner war positiv für APAs. Der Status des Antiphospholipid-Antikörpers korrelierte nicht mit dem Krankheitsstadium, der Histologie, dem International Prognostic Index oder dem Ansprechen auf die Behandlung. Die Kaplan-Meier-Überlebensanalyse zeigte keinen statistisch signifikanten Überlebensunterschied zwischen APA-positiven und APA-negativen Patienten. Es wurde festgestellt, dass nur der Leistungsstatus das Überleben signifikant vorhersagt.

Loss of smell function (Anosmia) is reported to be associated with novel coronavirus disease 2019 (COVID-19) infection. The present study was designed to evaluate the effectiveness of an indigenously developed prototype smell test to identify/diagnose asymptomatic COVID-19 positive individuals. A panel of five different odorants belonging to Indian household with unique and mutually exclusive odor were used to develop prototype kit to test the hypothesis. The developed prototype kit was tested at 2 centers (N = 49 and 34) with slight modifications. Simultaneously, the kit was also tested on 55 (N = 35 and 20) healthy controls. Our results indicate that otherwise asymptomatic COVID-19 positive individuals were having quantifiable deficit in smell sensation. Interestingly, the variable sensitivity of different odorants was observed in different patients. None of the healthy controls reported difficulty in sensing any of the odorant, whereas, some of healthy controls did misidentify the odorants. Overall, the present study provides a preliminary data that loss in smell sensation for various odorants can be exploited as a quick and affordable screening test to identify infected cases among at risk individuals.

BACKGROUND The prevalence of hypertension in primary hyperparathyroidism (PHPT) varies from 20-80% with data being based on office-based blood pressure measurements. Little is known about ambulatory monitoring of blood pressure (AMBP) in PHPT and changes in blood pressure (BP) variables post-curative parathyroidectomy. Hence, we conducted a prospective study wherein we performed AMBP in apparently normotensive patients with PHPT and reevaluated them 3 months post-curative parathyroidectomy. METHODS Consecutive patients with symptomatic PHPT aged 20 years and above underwent 24 hours AMBP at enrollment and at 3 months after successful parathyroidectomy. Pre- and postoperative BP variables were compared and correlated with serum calcium, creatinine and intact parathyroid hormone (iPTH) levels. RESULTS After exclusion, 17 symptomatic PHPT patients were enrolled in the study. AMBP detected hypertension in 4 (23.5%) patients. There was a significant reduction in the average nighttime systolic (P=0.007) and diastolic BP (P=0.034) after parathyroidectomy. However, the average 24 hours systolic/diastolic BP, daytime systolic/diastolic BP and average 24 hours mean arterial pressure did not differ before and after surgery. Non-dipping blood pressure pattern was seen in 53% of patients at presentation and persisted in 50% of cases after successful surgery. None of the biochemical parameters significantly correlated with any BP variable. CONCLUSIONS AMBP can help detect hypertension in patients with PHPT that remains unrecognized with routine office-based blood pressure measurement. In addition, AMBP detects loss of normal dipping pattern in BP that persists in almost half of the patients even after successful parathyroidectomy, perhaps because of permanent vascular damage induced by PHPT.

Background and aims The novel coronavirus disease (COVID-19) pandemic and the resulting nationwide lockdowns have posed a major challenge to the management of pre-existing and newly diagnosed endocrine disorders. Herein, we have summarized the management approaches of common endocrine disorders amid the ongoing pandemic. Methods We have performed an extensive literature search for articles in PubMed, EMBASE and Google Scholar databases till 25 May 2020, with the following keywords: “COVID-19”, “diabetes mellitus”, “thyroid disorders”, “primary adrenal insufficiency”, “Cushing's syndrome”, “pituitary tumors”, “vitamin D″, “osteoporosis”, “primary hyperparathyroidism”, “hypoparathyroidism”, “management”, “treatment” and “guidelines” with interposition of the Boolean operator “AND”. Results We have summarized the feasible strategies for the management of diabetes mellitus, hypothyroidism, hyperthyroidism, primary adrenal insufficiency (including congenital adrenal hyperplasia), Cushing's syndrome, pituitary tumors, osteoporosis, primary hyperparathyroidism and hypoparathyroidism amid the constraints laid down by the raging pandemic. In general, medical management should be encouraged and surgical interventions should be deferred whenever possible. Ongoing medications should be continued. Sick-day rules should be sincerely adhered to. Regular contact with physicians can be maintained through teleconsultations and virtual clinics. Conclusions Considering the burden of endocrine disorders in the general population, their management needs to be prioritized amid the ongoing COVID-19 pandemic., Highlights • The COVID-19 pandemic has posed a challenge to the management of common endocrine disorders. • Medical management should be preferred over surgery whenever feasible. • Ongoing medications should be continued and sick-day guidelines should be strictly followed.

Osteoporosis is a disease with a high burden of morbidity. For its accurate diagnosis, using indigenous data as reference standards is needed. However, normative data on bone density is lacking in India. Therefore, we aimed to determine the reference range for bone density for the healthy population of north India. Osteoporosis is a major public health problem around the globe including India, resulting in significant morbidity, mortality, and health care burden. However, the reference values used for its diagnosis are largely based on data from the western population, which may lead to over- or underdiagnosis of osteoporosis in Indians. Our study aimed to determine the reference range for bone mineral density for the healthy population of India. This is a cross-sectional study of 825 subjects (men 380, women 445) (median age: 41 years, IQR 32–55 years), recruited by a house-to-house survey. The population was stratified into decade-wise groups and biochemical measurements including renal and liver function tests, glycated hemoglobin, serum calcium, 25-hydroxyvitamin D, parathyroid hormone, and bone mineral density were performed in all the subjects. The T-scores for men aged > 50 years and post-menopausal women were calculated based on the data generated from this study in young men and women aged 20–40 years. According to the BMD manufacturer’s data, which is based on the western population, 70% of the Indian men (> 50 years) and 48% of the post-menopausal Indian women had osteopenia while 18% of the men and 25% of the women had osteoporosis. However, according to the re-calculated T-scores from the current study, only 56% and 7.2% of men and 33% and 5% of women had osteopenia and osteoporosis, respectively. An age-related decline in bone mineral density, as seen in the western population, was also seen in both Indian men and women. We have established a reference database for BMD in healthy Indian adult population, which may have clinical implications for the diagnosis and intervention strategies for the management of osteoporosis.

Highlights • Young adults with T1DM lacked adequate awareness about COVID-19. • Prevailing lockdown had reduced the routine physical activity of people with T1DM. • Suboptimal glucose control could be linked to reduction in physical activity., Aims To assess the awareness about COVID-19 and the problems being faced by young adults with T1DM amid nationwide lockdown in India. Methods A cross-sectional telephone-based qualitative interview study was conducted in young adults (aged 18–30 years) with T1DM amid lockdown. Following verbal consent, participants were asked 8 open-ended questions, 5 on awareness about COVID-19 and 3 catering to problems being faced concerning diet, physical activity and treatment amid lockdown. On average, 3 interviews were conducted per day with each lasting for 15−20 min. Interviews were recorded, transcribed and analyzed by qualitative content analysis. Results Thirty-two participants were interviewed; after exclusion of two poorly recorded interviews, 30 were finally analyzed. Mean age of participants was 22.4 ± 4.0 years (M:F = 8:7). Only 30%, 40% and 53% of participants were aware of modes of transmission (respiratory droplets and fomites), cardinal symptoms (fever, cough and breathing difficulty) and means of prevention (staying indoors, social distancing and regular hand washing), respectively. Majority of participants were unaware of additional risks associated with COVID-19 in diabetes mellitus. Most participants could continue with their routine diet and prescribed treatment regime, however, 90% reported a reduction in physical activity and 72% experienced worsening of glycemic control amid lockdown. Conclusions Young adults with T1DM lack adequate awareness about COVID-19. Increasing awareness and imparting diabetes self-management education via digital/print media is needed.

Background and aims Diabetes mellitus is associated with poor prognosis in patients with COVID-19. On the other hand, COVID-19 contributes to worsening of dysglycemia in people with diabetes mellitus over and above that contributed by stress hyperglycemia. Herein, we have reviewed the two-way interactions between COVID-19 and diabetes mellitus. Methods We have performed an extensive literature search for articles in PubMed, EMBASE and Google Scholar databases till April 25, 2020, with the following keywords: “COVID-19”, “SARS-CoV-2”, “diabetes”, “diabetes mellitus”, “SARS”, “infection” and “management of diabetes mellitus” with interposition of the Boolean operator “AND”. Results Compromised innate immunity, pro-inflammatory cytokine milieu, reduced expression of ACE2 and use of renin-angiotensin-aldosterone system antagonists in people with DM contribute to poor prognosis in COVID-19. On the contrary, direct β-cell damage, cytokine-induced insulin resistance, hypokalemia and drugs used in the treatment of COVID-19 (like corticosteroids, lopinavir/ritonavir) can contribute to worsening of glucose control in people with diabetes mellitus. Conclusions The two-way interaction between COVID-19 and diabetes mellitus sets up a vicious cycle wherein COVID-19 leads to worsening of dysglycemia and diabetes mellitus, in turn, exacerbates the severity of COVID-19. Thus, it is imperative that people with DM take all necessary precautions and ensure good glycemic control amid the ongoing pandemic., Highlights • People with diabetes mellitus have severe disease, acute respiratory distress syndrome and mortality in COVID-19. • COVID-19 in turn leads to worsening of glucose control in people with diabetes mellitus. • Drugs being used to treat COVID-19 can also adversely affect glucose control. • The complex two-way interaction between COVID-19 and diabetes mellitus sets up a vicious cycle.

Congenital adrenal hyperplasia (CAH) occurring in twins is extremely rare. Most of these cases are of classic salt-wasting CAH due to 21-hydroxylase enzyme deficiency. Only two cases of the simple virilising form of CAH have been reported previously, with variable clinical presentations. In this report, we describe a pair of monozygotic twins with classic simple virilising form of CAH, who had a simultaneous onset and similar severity of clinical manifestations. Genetic analysis of the CYP21A2 gene in twin 1 showed the pres-ence of two heterozygous pathogenic sequence variants, c.518T>A and c.955C>T in the CYP21A2 gene, consistent with a diagnosis of CAH due to 21-hydroxylase deficiency. We also present a brief review of previous cases of twins with CAH.

Fibrous dysplasia (FD) is a benign bone lesion characterized by replacement of normal bone with abnormal fibrous tissue, clinically manifesting as deformities, bone pains, and pathological fractures. The standard medical management for FD includes systemic bisphosphonate therapy. The efficacy of systemic bisphosphonate is however limited with minimal functional improvement and pain relief. Keeping the above lacunae in mind, we have made a solitary attempt at treating FD with locally administered zoledronic acid. A 25-year-old gentleman had presented to our institute with swelling and pain involving the left thigh and left lower leg. He was diagnosed as having polyostotic FD, confirmed on bone histopathology. He was administered 4 mg of zoledronic acid intravenously while 1 mg of the drug was injected locally into the femoral lesion under ultrasound and fluoroscopy guidance. There were no peri-procedural complications. At 6 months follow-up, there was marked improvement in pain scores at the left thigh, while that at the left leg remained unchanged. In addition, repeat bone scintigraphy showed a 20.8% and 25.3% reduction in anterior and posterior uptake values, respectively, at the left femur while that at the left tibia remained unaltered.

A 40-year-old gentleman presented with a history of multiple swellings involving his face, scalp, left axilla, back, and right thigh for the past 8 years. For the last 6 months, he developed intermittent low-grade fever, anorexia, weight loss, and gradually worsening breathlessness. On evaluation, the patient was found to have abnormally elevated absolute eosinophil count. Workup for the etiology of eosinophilia was unrewarding. All investigations related to an underlying myeloproliferative disorder were negative. Hence, a clinical possibility of angiolymphoid hyperplasia with eosinophilia (ALHE) was kept which was confirmed on histopathology. In the absence of other causes of hypereosinophilia, a clinical diagnosis of “associated hypereosinophilic syndrome” secondary to ALHE was made. He was managed with oral corticosteroids. The absolute eosinophil count reduced markedly, while the swellings showed a more gradual response, shrinking in size by about 50% following two months of therapy. The index case thus highlights a rather unusual presentation of ALHE.

Background and aims Mucormycosis is an invasive fungal infection and carries a significant morbidity and mortality. A number of cases of mucormycosis have been reported in association with COVID-19. In this study, a consortium of clinicians from various parts of India studied clinical profile of COVID-19 associated mucormycosis (CAM) and this analysis is presented here. Methods Investigators from multiple sites in India were involved in this study. Clinical details included the treatment and severity of COVID-19, associated morbidities, as well as the diagnosis, treatment and prognosis of mucormycosis. These data were collected using google spreadsheet at one centre. Descriptive analysis was done. Results There were 115 patients with CAM. Importantly, all patients had received corticosteroids. Diabetes was present in 85.2% of patients and 13.9% of patients had newly detected diabetes. The most common site of involvement was rhino-orbital. Mortality occurred in 25 (21.7%) patients. On logistic regression analysis, CT scan-based score for severity of lung involvement was associated with mortality. Conclusion Universal administration of corticosteroids in our patients is notable. A large majority of patients had diabetes, while mortality was seen in ∼1/5th of patients, lower as compared to recently published data.
