RESUMO

BACKGROUND: Adrenal insufficiency (AI) in hemoglobin E (HbE)/beta thalassemia, including evaluation of mineralocorticoid axis, had not been studied. AIMS AND OBJECTIVES: In this study, we attempted to evaluate the prevalence of AI in HbE/beta thalassemia and wanted to determine if the prevalence of AI varied according to severity of HbE/beta thalassemia and transfusion requirements. METHODS: In this observational, cross-sectional study, 104 patients with HbE/beta thalassemia were evaluated. Among them, 57 and 47 were transfusion dependent and non-transfusion dependent. According to Mahidol criteria, patients were classified into mild (n = 39), moderate (n = 39), and severe (n = 26) disease. Early morning (8 Am) serum cortisol, plasma ACTH, and plasma aldosterone, renin were measured. Patients with baseline cortisol of 5 to 18 µg/dL underwent both 1 µg and 250 µg short Synacthen test. According to these results, patients were classified as having either normal, subclinical, or overt (primary/secondary) adrenal dysfunction. RESULTS: Adrenal insufficiency was found in 41% (n = 43). Among them 83.7% (n = 34) had primary AI and 16.3% (n = 9) had secondary AI. Thirty-three patients (31%) with normal or elevated ACTH and with low or normal aldosterone with high renin were diagnosed as having subclinical AI. There was no difference in prevalence of AI between transfusion dependent and non-transfusion dependent (P = .56) nor was there was any difference in prevalence of AI according to disease severity (P = .52). CONCLUSION: Adrenal insufficiency is common in HbE/beta thalassemia and is independent of transfusion dependency and disease severity.

RESUMO

BACKGROUND: Once-weekly basal insulin icodec has been tested in clinical trials for efficacy and safety over currently available glargine-100 and degludec in different clinical settings for type 2 diabetes. We performed this meta-analysis to evaluate its overall safety and efficacy as compared to glargine-100 and degludec (nonicodec), from all available randomized controlled trials. METHODS: Seven trials comparing once-daily basal insulin analogs to once-weekly basal insulin icodec were included. Based on available information, outcomes in terms of HbA1c, fasting plasma glucose reduction, and increase in time in range (TIR) were compared. Side-effects were compared for overall hypoglycemia, severe hypoglycemia, and weight gain. The pooled effect size for continuously distributed data was measured as a reduction in "estimated differences in mean (with 95% CI)." For categorical data, the pooled effect size was measured as the Mantel-Haenszel risk ratio (with 95% CI). RESULTS: Analyzing against the nonicodec comparators together, the "estimated mean changes" in HbA1c and fasting plasma glucose favoring icodec were -0.22% (-0.35, -0.10) and -1.59 mg% (-9.26, 6.08) respectively. The "estimated mean increment" in weight for icodec was 0.64 kg (0.61, 0.67). The "estimated mean percentage" increment in TIR for icodec was 4.24% (2.99, 5.49). The Mantel-Haenszel risk ratios for all hypoglycemic events and severe hypoglycemia for icodec were 1.24 (1.02, 1.50) (P = .03) and 0.81 (0.31, 2.08) (P is not significant), respectively, suggesting a 24% increased incidence of all hypoglycemia with icodec. CONCLUSION: Once-weekly basal insulin icodec as compared to once-daily basal insulin analogs had a slight increase in the risk of overall hypoglycemia and weight gain, without any difference in severe hypoglycemia, with similar glycemic control (in terms of fasting plasma glucose, HbA1c, and TIR).

RESUMO

Impaired awareness of hypoglycaemia (IAH) is present in around 25-40% of individuals with type 1 diabetes mellitus (T1DM). Herein, we present a case of an adolescent with T1DM and IAH who had worse corneal nerve parameters compared to a T1DM adolescent without IAH. Small fibre abnormalities detected by corneal confocal microscopy in an objective easy-to-perform non-invasive test might be a surrogate indicator of underlying autonomic dysfunction in T1DM and IAH.

RESUMO

Introduction: A structured dedicated health programme for Type 1 diabetes mellitus (T1DM) has been initiated in the state of West Bengal, India. Aim: The aim is to provide comprehensive healthcare to all children, adolescents and young adults living with T1DM, along with the provision of free supply of insulin, glucose measuring devices, blood glucose test strips, and other logistics. The strategic framework for programme implementation is to utilise the infrastructure and manpower of the already existing non-communicable disease (NCD) clinic under National Health Mission. Methodology: Establishing dedicated T1DM clinics in each district hospital by utilising existing healthcare delivery systems, intensive training and hand-holding of named human resources; providing comprehensive healthcare service and structured diabetes education to all T1DM patients; and building an electronic registry of patients are important components of the programme. T1DM clinics run once a week on the same day throughout the state. All T1DM patients are treated with the correct dose of insulin, both human regular insulin and glargine insulin. Patients are routinely monitored monthly to ensure good glycaemic control and prevent complications of the disease. Routine anthropometric examination and required laboratory investigations are conducted in the set-up of the already existing NCD clinic. Ongoing monitoring and evaluation of the T1DM programme are being conducted in terms of glycated haemoglobin (HbA1c) values, growth and development, complication rates, psychological well-being, quality of life, and direct and indirect expenditure incurred by families. Through this programme, any bottlenecks or gaps in service delivery will be identified and corrective measures will be adopted to ensure better health outcomes for those living with T1DM.

RESUMO

An 18-year-old girl was evaluated for primary amenorrhea. She was diagnosed with hemoglobin E (HbE)/beta-thalassemia during childhood and needed blood transfusions every month to maintain adequate hemoglobin levels. She was started on thalidomide to reduce her transfusion requirements at 12 years of age and became transfusion independent after 6 months. She had normal stature and Tanner stage 4 sexual maturation, but she failed to attain menarche. Investigations revealed that she had elevated serum gonadotropin levels, indicating primary ovarian dysfunction. Her karyotype was 46,XX. Ultrasonographic examination demonstrated the absence of follicles in both ovaries. There was no evidence of abnormalities of the urogenital tract. Thalidomide was stopped, and she attained menarche spontaneously 3 months thereafter. Subsequently, her menstrual cycles were regular. Repeat ultrasound scans demonstrated the presence of ovarian follicles as well as an increase in ovarian volume. Mechanistic links between ovarian dysfunction and thalidomide remain to be found. One possibility is impaired blood flow and follicular development.

RESUMO

Background: Non-communicable diseases including metabolic health disorders are becoming area of concern for low/middle income countries with poor health-care resources. Present study was planned to assess the prevalence of metabolically unhealthy (MU) subjects in the community and proportion of the MU subjects having the risk of significant Non-alcoholic Fatty Liver Disease (NAFLD) using a step-wise evaluation strategy in a resource-poor setting. Methods: Study was performed in 19 community development blocks of Birbhum district, West Bengal, India. Every fifth member in the electoral list was included for the first step evaluation (n = 79,957/1,019,365, 7.8%) to detect any metabolic risk. Subjects with any metabolic risk in the first step (n = 9819/41,095, 24%) were taken for second step evaluation with Fasting blood glucose (FBG) and ALT. Subjects with elevated FBG and/or ALT in the second step (n = 1403/5283, 27%) were taken into third step evaluation. Finding: At least one risk factor was found in 51.4% (n = 41,095/79,957). 63% (n = 885/1403) of the subjects with metabolic abnormality (third step) had MU state making its overall prevalence of 1.1% (n = 885/79,957). 53% of MU subjects (n = 470/885) had 'persistently elevated ALT' suggesting the risk of having significant NAFLD. Interpretation: Step-wise evaluation strategy could detect the subjects at risk, actually having MU state and proportion of MU subjects at risk of having 'persistently elevated ALT' (surrogate of significant NAFLD) in the community with minimum utilization of scarce resources. Funding: This study was funded by Bristol Myers Squibb Foundation, USA, under the program 'Together on Diabetes Asia' (Project Number: 1205 - LFWB).

RESUMO

OBJECTIVE: Utility of corneal confocal microscopy (CCM) in children and adolescents with type 1 diabetes mellitus (T1DM) without neuropathic symptoms or signs and minimal abnormality in large and small nerve fiber function tests remains largely undetermined. This study aimed to evaluate the performance of CCM in comparison to thermal detection thresholds (TDT) testing and nerve conduction studies (NCS) for detecting neuropathy in children with T1DM. METHODS: A cohort of children and adolescents with T1DM (n = 51) and healthy controls (n = 50) underwent evaluation for symptoms and signs of neurological deficits, including warm detection threshold, cold detection threshold, vibration perception threshold, NCS, and CCM. RESULTS: Children with T1DM had no or very minimal neuropathic symptoms and deficits based on the Toronto Clinical Neuropathy Score, yet NCS abnormalities were present in 18 (35%), small fiber dysfunction defined by an abnormal TDT was found in 13 (25.5%) and CCM abnormalities were present in 25 (49%). CCM was abnormal in a majority of T1DM children with abnormal TDT (12/13, 92%) and abnormal NCS (16/18, 88%). CCM additionally was able to detect small fiber abnormalities in 13/38 (34%) in T1DM with a normal TDT and in 9/33 (27%) with normal NCS. CONCLUSION: CCM was able to detect corneal nerve loss in children with and without abnormalities in TDT and NCS.

RESUMO

BACKGROUND: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have recently been recommended as preferred agents for management of hyperglycemia in type 2 diabetes, primarily based on their ability to reduce a composite of major cardiovascular adverse events (3-point major adverse cardiovascular events [MACE]), predominantly by reducing cardiovascular death. However, reduction of the individual components, myocardial infarction (MI), or stroke (fatal and nonfatal) events have not been well explored. METHODS: In this meta-analysis, we included data available from cardiovascular outcome trials only, which were event-driven, randomized, and placebo-controlled. Pooled efficacy outcomes included Mantel Haenszel (MH) risk ratio using fixed model (with 95% CI) for fatal and nonfatal MI, stroke, and total MI and stroke. FINDINGS: Data from 4 eligible trials included 42,568 subjects. Total MACE, MI, and stroke were reported in 4176, 2157, and 1288 subjects, respectively. SGLT2is did not significantly reduce either MI or stroke individually or in totality. The MH risk ratio (95% CI) for fatal and nonfatal MI and stroke with different SGLT2is was found to be 0.93 (95% CI, 0.85-1.01) and 1.00 (95% CI, 0.89-1.11), respectively. For total atherosclerotic cardiovascular disease (ASCVD) events, MH risk ratio (95% CI) was 0.95 (95% CI, 0.89-1.02). For all nonfatal ASCVD (combined nonfatal MI and nonfatal stroke), MH risk ratio (95% CI) was 0.94 (95% CI, 0.88-1.02). INTERPRETATION: SGLT2is reduce MACE without any discernable significant reduction of the incidence of MI or stroke (fatal and nonfatal), probably implicating mechanisms unrelated to anti-atherogenic effects.

RESUMO

IMPORTANCE: This proof-of-concept paper demonstrates that driver mutations can be detected in plasma in differentiated thyroid tumors, and we were able to detect mutations in upto 80% malignant thyroid nodules. Additionally, cancer subtypes could also be predicted using a 8-gene panel. In almost 90% follicular adenoma, rat sarcoma virus (RAS) mutations were detectable. There was a strong agreement between driver mutations found in plasma samples, FNAC materials, and histopathology samples. This has potential as a noninvasive, preoperative diagnostic tool (particularly of clinical importance in indeterminate nodules) and may help in detection of residual tumor after surgery. Future research is warranted to test the role of this tool to detect tumor recurrence. OBJECTIVE: Ultrasonographic (USG) evaluation and fine-needle aspiration (FNA) are cornerstone for evaluation of thyroid neoplasm. Molecular technique including detection of driver mutation from FNA cytology (FNAC) material is an established modality. In this study, we explored the feasibility of using plasma cell-free nucleic acids to identify known driver mutations in differentiated thyroid neoplasm. DESIGN: Patients presenting with thyroid nodules underwent USG with Thyroid Image Reporting and Data Systems scoring and FNAC (Bethesda classification). All patients in Bethesda 3, 4, 5, 6 underwent surgery and histopathological confirmation. Patients in Bethesda 2 (cosmetic concerns, compressive symptoms) underwent surgery, and rest were presumed benign on the basis of USG, FNAC features, and clinical followup.). SETTING: Endocrinology clinic. PARTICIPANTS: Subjects with thyroid nodule. INTERVENTION(S) OR EXPOSURE(S): None. MAIN OUTCOME(S) AND MEASURE(S): Plasma sample, FNA, and histopathology material were evaluated for driver mutations (8-gene panel comprising BRAF-V600E, RET/PTC3, RET/PTC1, TERT promoter, HRAS, NRAS, KRAS, and PAX8-PPARG). RESULTS: A total of 223 subjects were recruited; of these 154 were benign and 69 had differentiated thyroid cancer. We were able to detect driver mutation from plasma in 55 subjects (79.71%) of all malignant patients, and 11 patients in benign category had RAS mutation (follicular adenoma). Rest of the benign nodules did not have any detectable driver mutations. CONCLUSIONS AND RELEVANCE: Plasma might be a viable noninvasive alternative source for detection of driver mutations (8-gene panel) in subjects with differentiated thyroid tumors and may have significant clinical utility.

RESUMO

OBJECTIVES: 46, XY difference/disorder of sex development (DSD) is a relatively uncommon group of heterogeneous disorders with varying degree of underandrogenization of male genitalia. Such patients should be approached systematically to reach an aetiological diagnosis. However, we lack, at present, a clinical practice guideline on diagnostic approach in 46, XY DSD from this part of the globe. Moreover, debate persists regarding the timing and cut-offs of different hormonal tests, performed in these cases. The consensus committee consisting of 34 highly experienced endocrinologists with interest and experience in managing DSD discussed and drafted a consensus statement on the diagnostic approach to 46, XY DSD focussing on relevant history, clinical examination, biochemical evaluation, imaging and genetic analysis. CONTENT: The consensus was guided by systematic reviews of existing literature followed by discussion. An initial draft was prepared and distributed among the members. The members provided their scientific inputs, and all the relevant suggestions were incorporated. The final draft was approved by the committee members. SUMMARY: The diagnostic approach in 46, XY DSD should be multidisciplinary although coordinated by an experienced endocrinologist. We recommend formal Karyotyping, even if Y chromosome material has been detected by other methods. Meticulous history taking and thorough head-to-toe examination should initially be performed with focus on external genitalia, including location of gonads. Decision regarding hormonal and other biochemical investigations should be made according to the age and interpreted according to age-appropriate norms Although LC-MS/MS is the preferred mode of steroid hormone measurements, immunoassays, which are widely available and less expensive, are acceptable alternatives. All patients with 46, XY DSD should undergo abdominopelvic ultrasonography by a trained radiologist. MRI of the abdomen and/or laparoscopy may be used to demonstrate the Mullerian structure and/or to localize the gonads. Genetic studies, which include copy number variation (CNV) or molecular testing of a candidate gene or next generation sequencing then should be ordered in a stepwise manner depending on the clinical, biochemical, hormonal, and radiological findings. OUTLOOK: The members of the committee believe that patients with 46, XY DSD need to be approached systematically. The proposed diagnostic algorithm, provided in the consensus statement, is cost effective and when supplemented with appropriate genetic studies, may help to reach an aetiological diagnosis in majority of such cases.

RESUMO

INTRODUCTION: Renal involvement in type 2 diabetes mellitus (T2DM) may be due to diabetes (diabetic kidney disease (DKD)), causes other than diabetes (non-diabetic kidney disease (NDKD)) or overlap of DKD and NDKD (mixed kidney disease group). Prevalence of NDKD and predictive value of clinical or biochemical indicators have been explored in retrospective cohorts with preselection biases warranting the need for prospectively conducted unbiased renal biopsy study. RESEARCH DESIGN AND METHODS: Consecutive subjects aged >18 years with T2DM and renal involvement with estimated glomerular filtration rate of 30-60 mL/min/m2 and/or albumin:creatinine ratio of >300 mg/g were offered renal biopsy. Prevalence of DKD, NDKD and mixed kidney disease was documented. Clinical/laboratory parameters of subjects were recorded and compared between groups and were tested for ability to predict histopathological diagnosis. RESULTS: We screened 6247 subjects with T2DM of which 869 fulfilled inclusion criteria for biopsy. Of the 869 subjects, biopsy was feasible in 818 subjects. Out of 818, we recruited first 110 subjects who agreed to undergo renal biopsy. Among those 110 subjects, 73 (66.4%) had DKD; 20 (18.2 %) had NDKD; and 17 (15.4 %) had mixed kidney disease. Subjects with NDKD as compared with DKD had shorter duration of diabetes (p<0.001), absence of retinopathy (p<0.001) and absence of neuropathy (p<0.001). Logistic regression revealed that only presence of retinopathy and duration of diabetes were statistically significant to predict histopathological diagnosis of DKD. 30% of DKD did not have retinopathy, thereby limiting the utility of the same as a discriminator. Use of traditional indicators of biopsy would have indicated a need for renal biopsy in 87.2% of subjects, though 64.5% of the subjects had DKD, who would not have benefitted from biopsy. CONCLUSION: NDKD and mixed kidney disease in T2DM with renal involvement are very common and traditionally used parameters to select biopsies are of limited value in clinical decision making.

RESUMO

BACKGROUND AND AIMS: The pathophysiology of different types of diabetes is incompletely understood. Fatty acid binding protein 4 (FABP4), an intracellular lipid chaperone, is secreted from adipocytes (during lipolysis) and macrophage. FABP4 is known to be associated with insulin resistance. However its precise role in the pathogenesis of T2DM is unclear. Fabkin, the hormonal complex of FABP4 with ADK (Adenosine Kinase) and NDPK (Nucleoside Diphosphate Kinase) is suggested to fill this gap in understanding pathogenesis. Herein, we summarize the role Fabkin in glucose homeostasis. METHODS: Published relevant manuscripts that discussed the effect of FABP4 and Fabkin on glucose homeostasis were reviewed. RESULTS: The formation of Fabkin complex is driven by the strong affinities of FABP4 to ADK and to inherent high-affinity interaction of ADK with NDPK. It does not have any definite receptors. The complex acts through the following pathways: i) by modulation of Glucose-Stimulated Insulin Signalling (GSIS) through extracellular ADP/ATP interaction via G-protein-coupled purinergic P2Y1 receptors in pancreatic ß-cells which are potently agonized by ADP and antagonized by ATP. Fabkin drives ADK to produce ATP, coupled with reduced generation of ADP. This results in low extracellular ADP/ATP ratio which leads to impairment of insulin secretion, ii) by regulating intracellular calcium dynamics iii) by producing Endoplasmic Reticulum (ER) stress. CONCLUSIONS: Fabkin may integrate energy balance with functions of metabolic organs and thus play a major role in glucose homeostasis.

RESUMO

OBJECTIVE: Sodium-glucose cotransporter-2 inhibitors (SGLT2is) in cardiovascular outcome trials (CVOTs) demonstrate cardiovascular (CV) safety and benefits. Some dedicated randomized controlled trials (RCTs) demonstrate benefit in terms of renal outcomes and hospitalization due to heart failure (HF). RCTs report differences in the secondary outcomes with respect to mortality (CV and/or all-cause). We undertook a meta-analysis of all SGLT2is for which in addition to CVOT, HF outcome/renal outcome studies are available to establish whether individual SGLT2is were able to prevent death. METHODS: We included available event-driven randomized, placebo-controlled CVOTs and dedicated RCTs of SGLT2is exploring renal outcomes and HF. We included 3 trials of empagliflozin, 3 of dapagliflozin, 2 of canagliflozin, and 2 of sotagliflozin. The efficacy outcomes included all-cause mortality and CV mortality. Hazard ratios (HRs) with 95% CIs were pooled for individual molecules. RESULTS: The HR for all-cause mortality including all trials was 0.86 (0.80-0.93). The HRs for all-cause mortality in empagliflozin (N = 16 738), dapagliflozin (N = 26 208), canagliflozin (N = 14 543), and sotagliflozin (N = 11 806) were 0.86 (0.69-1.08), 0.83 (0.72-0.97), 0.86 (0.75-0.97), and 0.95 (0.81-1.11), respectively. The HR for CV mortality including all trials was 0.85 (0.78-0.92). The HRs for CV mortality in empagliflozin, dapagliflozin, sotagliflozin, and canagliflozin were 0.81 (0.63-1.03), 0.88 (0.78-1.00), 0.89 (0.74-1.07), and 0.84 (0.72-0.98), respectively. CONCLUSION: SGLT2is as a class reduce both all-cause mortality and CV mortality. Canagliflozin possibly reduces both all-cause mortality and CV mortality, whereas dapagliflozin may reduce all-cause mortality but not CV mortality. Empagliflozin and sotagliflozin may reduce neither.

RESUMO

CONTEXT: The majority of women with Sheehan syndrome (SS) suffer from sexual dysfunction. Severe androgen deficiency is a major contributory factor. Dehydroepiandrosterone (DHEA) supplementation has been reported to have variable efficacious in improving female sexual dysfunction (FSD) in several trials but studies using DHEA in SS are not available. OBJECTIVE: We aimed to study the use of DHEA supplementation in patients with SS. METHODS: In this crossover trial, 28 participants with SS (age 39.7 ±â€…8.6 years) were divided into 2 groups (using block randomization) who received DHEA supplements (25 mg twice daily) or matched placebo sequentially for 3 months each. Female Sexual Functioning Index (FSFI) score and serum DHEA sulfate (DHEAS) were measured at baseline and after completion of each phase. Glycemic parameters, lipid profile, and liver enzymes were also measured to assess metabolic side effects. RESULTS: There was significant improvement in FSFI score from baseline to end of the study in the DHEA group compared with the placebo group (P = 0.006). Mean FSFI score and most of the individual domains of female sexual dysfunction (FSD) improved with DHEA significantly in both groups (P = 0.001 for each group with DHEA). In those who received DHEA first followed by placebo, FSFI declined significantly after placebo (P = 0.041) but remained at an acceptable level of sexual functioning. Serum DHEAS increased significantly with DHEA treatment. No significant changes in glycemic index, lipid profile, and liver enzymes were noted with DHEA treatment. CONCLUSION: A short duration of DHEA supplementation in women with SS with FSD is efficacious and safe.

RESUMO

BACKGROUND: Mucormycosis is a rare but serious fungal infection which has dramatically increased in post-COVID patients. There is a paucity of safety data on amphotericin B (amphoB) used for mucormycosis treatment. OBJECTIVES: The objective of this prospective, observational, active safety surveillance study was to evaluate the safety profile of amphoB in a cohort of hospitalized patients who were on the drug for suspected mucormycosis. MATERIALS AND METHODS: All suspected adverse drug reactions (ADRs) in hospitalized mucormycosis patients who had received amphoB were analyzed. The nature, severity, outcome of the ADRs were recorded and analyzed. RESULTS: Of the 77 patients enrolled, 70% had documented history of prior COVID-19 infection. 96% had comorbidities, the most common being diabetes. Majority received conventional amphotericin B deoxycholate formulation. 97% experienced at least one suspected ADR and the median ADR/patient was 3. Out of 214 ADRs, 91 were serious but there were no ADR-related deaths. The most common ADRs were hypokalemia (31.78%), infusion-related reactions (22.43%), and anemia (17.29%). Thirty-three patients had serum potassium <2.5 mEq/L, while 11 had serum magnesium <1.25 mg/dL. Doubling of pretreatment creatinine level was noted in 15 patients. Seventy percent ADRs were of "possible" category as per the World Health Organization Uppsala Monitoring Centre categorization. CONCLUSION: AmphoB deoxycholate use in mucormycosis patients was associated with a high incidence of electrolyte abnormalities and infusion-related reactions. All ADRs subsided with medical management and none were fatal. The safety data generated from this study may be useful in resource-limited settings where the far more expensive liposomal formulation is not being used.
