Diabetic foot ulcers, their characteristics, and trends in survival: Real world outcomes at a tertiary care facility in India.

AIMS: Characteristics of diabetes-related foot ulcers (DFU), association with recurrence and amputation are poorly described in the Asian Indian population. METHODS: A prospectively maintained database was reviewed to characterize DFU and its association with amputation and recurrence. RESULTS: Of 200 patients, 63.5 % were male, the median age was 62 years (Min-Max:40-86), and median BMI was 27.90 kg/m2 (Min-Max:18.5-42.7). Median duration of Diabetes mellitus was 15 years (Min-Max:2-43). Complete healing occurred at a median of three months (Min-Max:0.23-37.62). Amputation for the current ulcer was required in 43.4 % of individuals. Ulcer recurrence was documented in 42.4 % instances, 66.1 % evolving on the ipsilateral side. Previous amputation was associated with the risk of subsequent amputation (Adjusted OR-3.08,p-0.047). Median time to ulcer recurrence was 4.23 years among those with amputation, in contrast to 9.61 years in those with healing. Cardiovascular death was the commonest cause of mortality, followed by sepsis. At a median follow up of 6.08 years, mortality at 1,3,5 and 10 years was 2.5 %,2.5 %,8.2 % and 30.9 % respectively among those who underwent amputation versus 0 %,0 %,10.1 % and 24.5 % respectively for those who achieved healing. CONCLUSIONS: Patients with DFU in India incur amputations at rates higher than conventionally described. With previous amputation, subsequent amputation risk triples. Ten-year mortality is 25%-30 %. Underestimates of the burden of recurrence and mortality are consequential of limited follow-up.

Prevalence of type 2 diabetes among tribal population of india: a multi-centric cross-sectional study.

BACKGROUND: The perception among healthcare workers is that the Indian tribal (indigenous) population are less affected by diabetes. This paper reports the prevalence of type 2 diabetes and its associated factors among tribal populations from six districts across India. METHODOLOGY: Random blood glucose (RBG) and fasting blood glucose (FBG) were measured for 8486 and 3131 adults, respectively, with a glucose meter. FBG ≥ 126 mg/dL (7.0 mmol/L) and RBG ≥ 200 mg/dL (11.1 mmol/L) were used to diagnose diabetes. In addition, blood pressure, anthropometric (height, weight, waist and hip circumferences), socio-demographic (age, gender, education, type of tribe and type of village) and behavioural data (tobacco smoking, non-smoking tobacco use and alcohol consumption) were collected. RESULTS: The overall prevalence of type 2 diabetes, based on RBG, was 4.77% (95% CI: 4.33-5.25). The prevalence of type 2 diabetes and prediabetes, based on FBG, was 6.80% (95% CI: 5.95-7.74) and 8.69% (7.72-9.73), respectively. The prevalence of type 2 diabetes was significantly associated with age (p<0.001), smokeless tobacco use (p < 0.05), hypertension (p < 0.001) and obesity (p < 0.01). CONCLUSION: The prevalence of type 2 diabetes among the Indian tribal population reported in this study is less than the national average of 7.3% for the general population. Hypertension and obesity were the major risk factors. Due to changing behavioural patterns, including dietary behaviour, there is likely to be an increase in the prevalence of hypertension and obesity, which further leads to increased prevalence of type 2 diabetes. Hence, appropriate interventions are to be initiated by the primary healthcare system.

A novel simple disposition index (SPINA-DI) from fasting insulin and glucose concentration as a robust measure of carbohydrate homeostasis.

AIMS: The widely used dynamic disposition index, derived from oral glucose tolerance testing, is an integrative measure of the homeostatic performance of the insulin-glucose feedback control. Its collection is, however, time consuming and expensive. We, therefore, pursued the question if such a measure can be calculated at baseline/fasting conditions using plasma concentrations of insulin and glucose. METHODS: A new fasting-based disposition index (structure parameter inference approach-disposition index [SPINA-DI]) was calculated as the product of the reconstructed insulin receptor gain (SPINA-GR) times the secretory capacity of pancreatic beta cells (SPINA-GBeta). The novel index was evaluated in computer simulations and in three independent, multiethnic cohorts. The objectives were distribution in various populations, diagnostic performance, reliability and correlation to established physiological biomarkers of carbohydrate metabolism. RESULTS: Mathematical and in-silico analysis demonstrated SPINA-DI to mirror the hyperbolic relationship between insulin sensitivity and beta-cell function and to represent an optimum of the homeostatic control. It significantly correlates to the oral glucose tolerance test based disposition index and other important physiological parameters. Furthermore, it revealed higher discriminatory power for the diagnosis of (pre)diabetes and superior retest reliability than other static and dynamic function tests of glucose homeostasis. CONCLUSIONS: SPINA-DI is a novel simple reliable and inexpensive marker of insulin-glucose homeostasis suitable for screening purposes and a wider clinical application.

Understanding the predictive accuracy of the InsuTAG index over other surrogate indices in normoglycaemic, non-obese males from Southern India.

We aimed to evaluate the predictive accuracy of InsuTAG index against M value of the hyperinsulinaemic-Euglycaemic clamp (HEC) procedure and fasting surrogate indices of insulin sensitivity/resistance in young, normoglycaemic, Asian Indian males. HEC studies were done in young (mean age 19.7 ± 1 years), non-obese (mean BMI 19.2 ± 2.6 kg/m2), normoglycemic Asian Indian males (n = 110) and the M value was calculated. Surrogate indices namely InsuTAG index, HOMA-IR, FG-IR, QUICKI and McAuley index were calculated. Pearson's correlation and ROC-AUC at 95% CI were applied. Significant negative correlation was observed for InsuTAG index with the M value (r - 0.23, p = 0.01), McAuley index (r - 0.65, p < 0.01), QUICKI (r - 0.34, p < 0.01) and FGIR (r - 0.35, p < 0.01). Significant positive correlations of InsuTAG index were observed for BMI and waist circumference. The ROC-AUC was higher for InsuTAG index (0.75) than FGIR (0.30), QUICKI (0.31), and McAuley index (0.20). The InsuTAG cut-off value ≥ 19.13 showed 66.7% sensitivity and 69.2% specificity in this study group.

Do Bone Mineral Density, Trabecular Bone Score, and Hip Structural Analysis Differ in Indian Men with Parkinson's Disease? A Case-Control Pilot Study from a Tertiary Center in Southern India.

Objective: Parkinson's disease (PD) is a neurodegenerative condition that is characterized by bradykinesia, rigidity, and gait instability. Inherent to this condition is an increased predisposition to falls and fractures. Bone health in Parkinson's disease in India has not been studied thus far. This study aimed to assess the bone mineral density (BMD), trabecular bone score (TBS), and hip structural analysis (HSA) in Indian men with PD and compare them with matched controls. Methodology: A case-control study done at a tertiary care center from southern India. Bone biochemistry, BMD, TBS, and HSA were assessed. Results: Among 40 cases and 40 age, gender, and body mass index (BMI)-matched controls, there was no significant difference in BMD between both groups. The mean (SD) TBS at the lumbar spine [1.349 (0.090)] was significantly (P = 0.019) lower in men with PD as compared to matched controls [1.401 (0.089)]. Among the parameters of HSA, the buckling ratios were significantly higher at the femoral neck [11.8 (2.2) vs 9.4 (2.2); P = 0.001] and inter-trochanteric region [9.4 (2.1) vs 7.8 (1.4); P = 0.002] among cases as compared to matched controls. Vitamin D deficiency was significantly higher in this cohort of patients as was bone turnover marker indicating bone loss and a high bone turnover state. Conclusion: A comprehensive bone health assessment comprising BMD, TBS, and HSA may be required to capture all aspects of bone strength in Indian men with PD as BMD assessment as a stand-alone tool may not suffice to obtain all information pertaining to fracture risk in these individuals.

Hypertension Prevalence, Awareness, Treatment, Control and Risk Factors in Tribal Population of India: a Multi-Centric Cross-Sectional Study.

The prevalence of hypertension is increasing in the tribal population of India. Lifestyle modifications, including dietary changes and acculturation, are the main reasons for the high prevalence of hypertension among the Indian indigenous (tribal) population. This paper reports hypertension prevalence, awareness, treatment, control and risk factors among tribes in five districts of different geographical zones of India. A cross-sectional study was conducted among the adult tribal population of 7590 from these states. Data related to blood pressure, anthropometry, demographic and behavioural variables were collected with prior consent from the participants. The prevalence of hypertension is 34.0% and 28.3% among men and women, respectively. Of the total hypertensives, 27.5% were aware of their hypertension status; of them, 83.9% were receiving treatment, and blood pressure was in control among 33.5% of patients who were receiving treatment. Age, alcohol intake, sedentary lifestyle, Particularly Vulnerable Tribal Groups status and body mass index are found to be significantly associated with the prevalence of hypertension. The prevalence of hypertension is high among these tribal populations, which could be due to modernization and acculturation. Awareness and treatment-seeking behaviour are poor. Hence, early screening, awareness campaigns for seeking treatment, and health promotion are immediately required. Comprehensive health promotion programs need to promote lifestyle modification and re-orientation of the primary health care system to improve availability and accessibility to hypertension screening and treatment.

A Rare Case of Primary Hyperparathyroidism Presenting as a C2 Brown Tumor-Plain Radiography Has yet again Proved Indispensable in Clinching the Diagnosis.

A brown tumor is one of the manifestations of hyperparathyroidism. It is a rare type of bone lesion that most often occurs in mandible, ribs, and large bones. Spinal involvement is extremely rare. We report an unusual case of a brown tumor of the axis vertebra in a 33-year-old male who presented to the orthopaedic clinic with posttraumatic C2 vertebra fracture and myelopathy. To plan further fixation and stabilization of C2 fracture, the patient underwent a plain radiograph and magnetic resonance imaging (MRI) of the cervical spine. The available routine chest radiograph at the time of MRI reporting clinched the diagnosis of primary hyperparathyroidism with a brown tumor of the axis vertebra. Thus, familiarity with subtle radiographic findings of this condition not only led to early diagnosis and appropriate treatment but also avoided unnecessary C2 biopsy and hardware fixation.

Cathepsin K Mutation-A Subtle Clinical Presentation.

Context: Pyknodysostosis is an uncommon inherited disorder associated with consanguinity, often presenting with sclerotic bone disease, short stature, dysmorphic features, and recurrent fragility fractures at an early age. Case: A 34-year-old woman was evaluated for the cause of recurrent fragility fractures. She was born of a third-degree consanguineous marriage and had a twin brother who was of short stature. The index patient had a height of 141 cm, dysmorphic features including frontoparietal bossing, blue sclera with short stubby fingers and toes. Radiological evaluation revealed diffuse osteosclerosis with acro-osteolysis exclusively in the toes, apart from mid-facial hypoplasia, lack of pneumatization of the paranasal sinuses, dental abnormalities, and scoliosis. Dual-energy x-ray absorptiometry revealed increased bone mineral density. Based on the clinical features, the patient was tested for cathepsin K gene variants using next-generation sequencing and was found to be positive for a novel homozygous c.224T>C, p.Met75Thr likely pathogenic missense variant. Discussion: This patient presented at a later age than expected with recurrent fragility fractures and the diagnosis was not suspected till adulthood, owing to the subtle clinical features. Confirmation with genetic testing helped in establishing the diagnosis. Conclusion: Pyknodysostosis, although uncommon, is one of the differential diagnoses for diffuse osteosclerosis presenting with recurrent fragility fractures. Next-generation sequencing in an appropriate setting may confirm the diagnosis.

Comprehensive evaluation of patterns of hypoglycemia unawareness (HUA) and glycemic variability (GV) in patients with fibrocalculous pancreatic diabetes (FCPD): A cross-sectional study from South India.

OBJECTIVES: Hypoglycemia unawareness (HUA) in patients with FCPD is common with an unclear etiology. We evaluated the prevalence, characteristics of HUA, glycemic variability (GV), its possible association with pancreatic glucagon secretion & cardiac autonomic function in patients with FCPD. METHODS: A two-week ambulatory glucose profile (AGP) and cardiac autonomic function test was done in patients with FCPD (n = 60), and categorized into UNAWARE (n = 44) and AWARE (n = 16) groups based on the Hypoglycemia Unawareness Index (HUI) score. Glycaemic variability was assessed from the AGP data using Easy GV 9.0.2 software. A subset of patients from both the groups (n = 11) underwent a mixed-meal challenge test and were compared with healthy individuals (controls; n = 11). RESULTS: HUA was evidenced in 73% (44/60) of patients with FCPD. Significant hypoglycemia, nocturnal hypoglycemia, duration of hypoglycemia and poor cardiac autonomic functions (p = 0.01) were prominent in the UNAWARE group. The overall GV was greater in the UNAWARE group. In the UNAWARE group, significantly reduced fasting and post prandial glucagon levels negatively correlated with HUI (r = -0.74, p < 0.05) and GV-hypoglycemia indices (p < 0.05) In contrast, significantly higher post prandial glucagon levels in the AWARE group positively correlated with post prandial hyperglycemia (r = 0.61, p < 0.05). CONCLUSION: Heterogeneity in patterns of glucagon secretion were significantly associated with HUA and GV. Reduced glucagon levels contribute to greater risks of HUA, nocturnal hypoglycemia and greater GV, while hyperglucagonemia predisposes to postprandial hyperglycemia and hypoglycemia awareness in patients with FCPD.

Does hip structural analysis confer additional benefit to routine BMD assessment in postmenopausal women with hip fracture? A study from a tertiary center in southern India.

This study from southern India showed that proximal hip geometry was significantly impaired in postmenopausal women with femoral neck fracture. The trabecular bone score (TBS), which is reflective of bone microarchitecture, was also significantly impaired in patients with fracture. INTRODUCTION: There is limited information with regard to comprehensive bone health in Indian postmenopausal women with neck of femur fracture. We studied the bone mineral density (BMD), trabecular bone score (TBS), proximal hip geometry, and bone mineral biochemistry in postmenopausal women with and without femoral neck fractures. METHODS: This was a cross-sectional study conducted at a tertiary care center in South India. BMD, TBS, and hip structural analysis (HSA) were assessed using a dual-energy X-ray absorptiometry (DXA) scanner. Bone mineral biochemical profiles were also studied. RESULTS: A total of 90 postmenopausal women with acute femoral neck fracture with mean (SD) age of 63.2 (6.1) years and 90 age-matched controls were included. The prevalence of osteoporosis was higher among cases as compared to controls (83.3% vs 47.8%; P < 0.001). Degraded bone microarchitecture (TBS value < 1.200) was more frequent among women with hip fracture as compared to controls (46.7% vs 31.1%; P = 0.032). Cross-sectional moment of inertia (CSMI) was significantly lower at the narrow neck (NN) and inter-trochanteric (IT) region in cases (P < 0.05) and buckling ratio (BR) was significantly higher at all three sites in postmenopausal women with femoral neck fracture as compared controls. Multivariate logistic regression analysis showed that femoral neck osteoporosis, low CSMI at NN and high BR at NN and femoral shaft emerged as factors significantly associated with femoral neck fractures. CONCLUSION: This study highlights that impaired parameters of proximal hip geometry and a low trabecular bone score may be significantly associated with femoral neck fractures in postmenopausal women.

Diabetes Mellitus With Renal and Müllerian Anomalies.

OBJECTIVE: Maturity-onset diabetes of the young (MODY) type 5 is caused by an autosomal dominant mutation in the HNF1B gene. Our objective was to report a case of a young girl with bicornuate uterus and recurrent renal stones with diabetes mellitus (DM) without a family history that was diagnosed to be MODY 5. CASE REPORT: A 12-year-old girl presented with recurrent renal stones that were managed with lithotripsy and double-J stenting at various time points. At the age of 14 years, she was found to have a bicornuate uterus with an absent cervix and vagina. She was diagnosed with DM at the age of 16 years without a preceding history of osmotic symptoms or steatorrhea. Although there was no family history of young-onset diabetes, given her long-standing history of müllerian abnormalities, renal cysts, and pancreatic hypotrophy, she was evaluated for MODY. Using the next-generation sequencing, she was found to be positive for a reported HNF1B gene pathogenic mutation c.494G>A (p.Arg165His), confirming a diagnosis of MODY 5. DISCUSSION: There is a significant overlap in clinical criteria for type 2 DM and MODY in the Asian Indian population. The HNF1B gene mutation is difficult to diagnose as none of the clinical manifestations are pathognomonic and many lack a family history of DM. Diagnostic algorithms with specific clinical and biochemical criteria along with pancreatic imaging can help in case detection and direct toward particular genetic mutation analysis. CONCLUSION: We suggest that genetic testing be offered to patients with otherwise unexplained DM and such genitourinary anomalies.

Differentials in dietary intake of macro and micronutrients in patients with type 2 diabetes and foot ulcers: Observations from a pilot study.

BACKGROUND AND AIM: The dietary profiles of patients with type 2 diabetes mellitus (T2DM) from Southern India have been infrequently studied. We aimed to study the differences in dietary intake of macro and micronutrients in elderly patients of Type 2 diabetes mellitus (T2DM), with and without foot ulcers. METHODS: Elderly patients with T2DM and foot ulcers (n = 79; mean age: 60.6 years) and those without foot ulcers (n = 59; mean age: 55.0 years) were studied. Biochemical evaluation for measures of glycemia, lipids and albumin were done and staging of foot ulcers was done using Wagner's scale. A 24-hour dietary recall was administered to quantify the mean daily intake (MDI) of macro, micronutrients and trace elements from portion sizes of food items consumed and compared to the recommended dietary allowance (RDA) for Indians aged 55 years and above. RESULTS: In patients with T2DM and foot ulcers, the MDI of carbohydrates, fats and phosphorus were significantly higher whereas the MDI of proteins and micronutrients namely zinc, folic acid, iron and carotene were lower than the RDA. Elderly patients with nephropathy and longer duration of T2DM have higher odds of developing foot ulcers, when compared to patients without foot ulcers. CONCLUSION: Elderly patients with T2DM and foot ulcers were deficient in dietary intake of proteins and micronutrients inclusive of carotene, folic acid, zinc, and Iron. Clinical care, regular monitoring of dietary intake and appropriate correction of nutritional deficiencies will aid in the management of diabetic foot ulcers.

Exocrine pancreatic insufficiency related fat malabsorption and its association with autonomic neuropathy in Asian Indians with type 2 diabetes mellitus.

BACKGROUND AND AIMS: We aimed to estimate the prevalence of exocrine pancreatic insufficiency (EPI) related fat malabsorption & to correlate it with measures of autonomic neuropathy in patients with T2DM from India. METHODS: Patients with T2DM (cases; n = 118) and normo-glycaemic individuals (controls; n = 82) underwent anthropometry and biochemical evaluation at baseline. The 72-hours fecal fat excretion was estimated by the Van de Kamer's titration method. Autonomic neuropathy was evaluated using an automated analyzer. RESULTS: The prevalence of EPI related fat malabsorption in cases was 45% (n = 53; 72 hours mean fecal fat level = 22.7 ± 5.6 g/day). Dysfunctions in the parasympathetic nervous system (PNS; 86.7%; p < 0.05), sympathetic nervous system (SNS; 92.4%; p < 0.05), and both; PNS + SNS (83.1%; p < 0.05) were significant. Amongst measures of PNS dysfunction, there was a significantly higher percentage of abnormal expiration: inspiration ratio (45.3%) and the 30:15 ratio (84.9%) (p < 0.05) in patients with T2DM and EPI related fat malabsorption. CONCLUSION: In this cross-sectional cohort of Asian Indian patients with T2DM (n = 118), EPI related fat malabsorption correlates significantly with autonomic dysfunction in patients with T2DM. However, these preliminary data need to confirmed in trials with more robust design.

Bone Mineral Density and Body Composition in Males with Motor Neuron Disease: A Study from Teaching Hospital in Southern Part of India.

BACKGROUND: Osteoporosis and sarcopenia are important aspects of motor neuron disease (MND). Individuals with amyotrophic lateral sclerosis (MND-ALS) have an increased risk of falls and fractures. Currently, the standard of care does not involve a routine assessment of bone mineral density (BMD) and body composition in these patients. We aimed to assess BMD, bone mineral parameters and body composition in men with MND and compared them with healthy controls. METHODS: Consecutive males between 50 and 80 years of age diagnosed as MND-ALS by revised El Escorial criteria and able to walk unassisted attending Neurology outpatient clinic were recruited into the study. Age, gender and body mass index (BMI) matched healthy controls were recruited from the local community. BMD and body composition were assessed by dual-energy x-ray absorptiometry (DXA). Bone mineral parameters and bone turnover markers (BTMs) were also assessed in them. RESULTS: A total of 30 subjects with MND-ALS and 33 controls were recruited. The mean age (years) was 59.2 in cases and 61.2 in controls. The mean BMD (g/cm2) between the two groups was similar; however, BTMs were significantly higher in the MND group (P < 0.05). Subjects with MND-ALS had significantly lower mean appendicular lean mass (ALM) (19.9 versus 22.4 kg; P = 0.007) and ALM corrected for BMI than the healthy control group (0.858 versus 0.934 kg/kg/m2; P = 0.034). Sarcopenic obesity (Percentage fat mass >27% + ALM/BMI <0.786 kg/kg/m2) was more prevalent in MND-ALS compared to controls (44.5% versus 16.7%; P = 0.03). CONCLUSION: Although BMD was not significantly different between subjects with MND-ALS and healthy controls, BTMs were significantly higher in the MND group indicating a high bone turnover state. Sarcopenia and sarcopenic obesity were also more in MND-ALS group than controls. Routine assessment for bone health parameters and body composition indices may be included in management of the patients with MND.

Case of functioning thoracic paraganglioma.

Functioning thoracic paraganglioma (PGL) is rare in clinical practice. We present a 33-year-old man with this pathology, who came with right-sided chest pain and was found to have a right-sided paravertebral mass. Fine needle aspiration cytology revealed a PGL. Urine normetanephrine was elevated and meta- iodobenzylguanidine scan showed increased tracer uptake in the right hemithorax, suggestive of a functioning neuroendocrine tumour. The patient was subjected to right PGL excision by video-assisted thoracoscopic surgery, after adequate preoperative preparations. The perioperative period was uneventful, except for a transient rise in blood pressure during the surgery. His blood pressure continued to be normal in the postoperative period. In any patient with a paravertebral mass, the possibility of PGL should be kept in mind even if the patient is normotensive. Making a preoperative diagnosis is important, because excision of functioning PGL without adequate preoperative preparation may be detrimental.

The triglyceride/glucose ratio is a reliable index of fasting insulin resistance: Observations from hyperinsulinaemic-euglycaemic clamp studies in young, normoglycaemic males from southern India.

BACKGROUND & AIMS: Non-obese Asians have a high propensity to develop insulin resistance. Therefore, screening such individuals for insulin resistance using simple surrogate indices is important. In this study, we aimed to validate the triglyceride-glucose (Tg/glu) ratio against the M value of hyperinsulinaemic-euglycaemic clamp (HEC) procedure and other surrogate indices of insulin resistance in normoglycaemic Indian males from Southern India. METHODS: A cohort of 105 normoglycaemic males (mean BMI: 19.2 ± 2.6 kg/m2) underwent HEC procedure. Surrogate indices of insulin resistance viz. the triglyceride-glucose (Tg/Glu) ratio, the triglyceride-glucose index, the McAuley's index, the HOMA-IR, the QUICKI, the fasting glucose to insulin ratio (FG-IR), and the fasting C- peptide index were calculated and correlated with the M value. The cut-off value for the Tg/Glu ratio was obtained using the Receiver Operator Characteristics (ROC) with Area under curve (AUC) analysis at 95% confidence interval (CI). The P value < 0.05 was considered statistically significant. RESULTS: The Tg/Glu ratio demonstrated significantly higher AUC (0.81), when compared to the Tg × glu index (0.63), 20/fasting C peptide × fasting plasma glucose index (0.55), HOMA-IR (0.47), QUICKI (0.26), FGIR (0.12) and McAuley's index (0.18). For the Tg/Glu ratio, a cut-off value ≥ 1.19 had high sensitivity (80%) and specificity (79%) values (PPV: 16%; NPV: 98.8%) respectively. CONCLUSION: The Tg/Glu ratio can be used as a reliable surrogate index to screen for risk of insulin resistance in lean, normoglycaemic males from Southern India.

Necrotizing soft tissue infection of the upper extremities in patients with diabetes mellitus in a tertiary care center-a retrospective study.

BACKGROUND: Necrotizing soft tissue infection (NSTI) of the upper extremities is a rare, but potentially life-threatening infection in patients with type 2 diabetes mellitus (T2DM). We analyzed the clinical characteristics and the outcome of NSTI of upper extremities in these patients. METHODS: This was a retrospective study analyzing the clinical characteristics and the outcomes of 33 T2DM patients with NSTI of upper extremities, who were treated in the department of hand surgery between January 2011 and December 2017. RESULTS: Predisposing factors for NSTI were recognized in 16 (48.5%) patients. Eleven (33.3)% patients had septic shock while ten (30.3%) had acute renal insufficiency at the time of presentation, of which six required dialysis. The mean glycosylated hemoglobin was 9.6(±2.6)% and the random plasma glucose at admission was 271(±96) mg/dl. Monomicrobial infection was seen in 16(49%) patients and polymicrobial infection in 9(27%) patients. Gram-positive causation was found in 25(66%) patients. Twelve (36.4%) patients required amputation, six (18.2%) of which were major. Death occurred in more than one-fifth (21.2%) of the patients during treatment. CONCLUSION: Necrotizing soft tissue infection of the upper extremities in T2DM is associated with increased risk of severe infection, amputation and mortality.
