Chronic Dis Transl Med 2024; 10:22-30. [PMID: 38450303 PMCID: PMC10914015 DOI: 10.1002/cdt3.98] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 08/28/2023] [Accepted: 09/21/2023] [Indexed: 03/08/2024] Open
Abstract
Insulin is used as a therapeutic agent in patients with diabetes, and cutaneous lipohypertrophy (LH) and localized insulin-derived amyloidosis (LIDA) are well-known adverse effects associated with insulin injections. The clinical implications, management, assessment methods, and pathological differentiation of LH and LIDA have been recently updated. This review was to update our knowledge of the pathological differentiation, effects of insulin absorption, hypoglycemic events, and recent assessment methods for LH and LIDA. A scoping review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses extension for Scoping Reviews guidelines. Original studies and case reports in English were also included. PubMed and Scopus databases were searched for keywords to identify papers published up to January 2022. A total of 113 studies were identified through a database search, and 31 were eligible for inclusion in this scoping review. In the 31 studies included in this review, patients with type 2 diabetes had high frequencies of LH and LIDA. LH outcome parameters were assessed using pathological findings and imaging. LIDA is mainly determined by pathological methods, such as hematoxylin and eosin and Congo red staining. Several in vitro and in vivo LIDA models of LIDA have been developed. These results suggest that pathological analysis is required to identify LH and LIDA. It is important to consider LIDA, as it likely influences insulin adsorption and glycemic control. Although several studies have evaluated the LIDA process, little is known about the mechanisms underlying the development of adverse effects associated with insulin injections.

Diabetol Int 2024; 15:41-57. [PMID: 38264219 PMCID: PMC10800326 DOI: 10.1007/s13340-023-00665-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Accepted: 09/22/2023] [Indexed: 01/25/2024]
Abstract
Aim In order to achieve good glycemic control, the prevention and management of insulin balls is important for diabetic patients during insulin therapy. However, insulin balls still occur within the clinical setting. This review evaluated the effectiveness of programs designed to manage insulin balls. Methods A scoping review was conducted based on the Japanese and English literature available from a systematic literature search conducted from January 1964 to March 2022. Three databases were searched: PubMed, CINAHL, and Ichushi-Web. Results A total of 33 articles met the inclusion criteria, which consisted of 3 for prevention management of insulin balls and 30 for management after the occurrence of insulin balls. Findings for prevention management suggested that the insulin injection technique education (avoidance of repeated injections to the same site) and providing knowledge (about insulin balls) prevented the appearance of insulin balls. As for post-occurrence management, insulin injection technique education (avoidance of injections to the insulin ball, avoidance of repeated injections to the same site, and switching the injection site) improved blood glucose control. Hypoglycemia was observed in all studies that included an assessment of hypoglycemia. None of the studies evaluated long-term effects of either preventive or post-occurrence management. Conclusions Providing insulin injection technique education is an effective management protocol for insulin balls. Moreover, education about hypoglycemia is important for patients with insulin balls. Further studies to investigate the long-term effects in the management of insulin balls are needed.

Abstract
Lipohypertrophy is a common skin complication associated with insulin-treated diabetes. The impact of lipohypertrophy as a contributing factor to suboptimal glycemic control, glucose variability, and hypoglycemia is often under-recognized by health care professionals. In a recent Webinar on April 26, 2023, Diabetes Technology Society asked international experts to provide updates on the latest knowledge related to lipohypertrophy for practicing clinicians and educators, researchers, and industries involved in insulin delivery. A recording of the Webinar is freely available on the Diabetes Technology Society Web site (https://www.diabetestechnology.org/).

Abstract
Objective: This study examined subcutaneous tissue changes at sites used by continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM), and tested whether these changes, if any, were associated with glycated hemoglobin (HbA1c). Research Design and Methods: This prospective study investigated recently used CSII or CGM sites in 161 children and adolescents during the first year after initiation of a new diabetes device. Subcutaneous changes such as echogenicity, vascularization, and the distance from the skin surface to the muscle at CSII and CGM sites were assessed by ultrasound. Results: The distance from skin surface to muscle fascia at both the upper arm and abdomen was influenced by age, body mass index z-score, and sex. Especially in boys and the youngest, the depth of many devices outreached the mean distance. The mean distance for boys at the abdomen and upper arm ranged from 4.5-6.5 mm and 5-6.9 mm for all ages, respectively. Hyperechogenicity at CGM sites was 4.3% after 12 months. The frequency of subcutaneous hyperechogenicity and vascularization at CSII sites increased significantly over time (41.2% to 69.3% and 2% to 16% respectively, P < 0.001 and P = 0.009). Hyperechogenicity in the subcutis was not a predictor of elevated HbA1c (P = 0.11). Conclusion: There is large variation in the distance from the skin surface to the muscle fascia and many diabetes devices reach even deeper. Hyperechogenicity and vascularization increased significantly over time at CSII sites, but not CGM sites. The importance of hyperechogenicity for insulin absorption is unclear and further investigations are needed. Clinical Trial Registration number: NCT04258904.

Abstract
Therapeutic macromolecules possess properties such as size and electrostatic charge that will dictate their transport through subcutaneous (SC) tissue and ultimate bioavailability and efficacy. To improve therapeutic design, platforms that systematically measure the transport of macromolecules as a function of both drug and tissue properties are needed. We utilize a Transwell chamber with tunable collagen-hyaluronic acid (ColHA) hydrogels as an in vitro model to determine mass transport of macromolecules using non-invasive UV spectroscopy. Increasing hyaluronic acid (HA) concentration from 0 to 2 mg/mL within collagen gels decreases the mass transport of five macromolecules independent of size and charge and results in a maximum decrease in recovery of 23.3% in the case of bovine immunoglobulin G (IgG). However, in a pure 10 mg/mL HA solution, negatively-charged macromolecules bovine serum albumin (BSA), β-lactoglobulin (BLg), dextran (Dex), and IgG had drastically increased recovery by 20-40% compared to their performance in ColHA matrices. This result was different from the positively-charged macromolecule Lysozyme (Lys), which, despite its small size, showed reduced recovery by 3% in pure HA. These results demonstrate two distinct regimes of mass transport within our tissue model. In the presence of both collagen and HA, increasing HA concentrations decrease mass transport; however, in the absence of collagen, the high negative charge of HA sequesters and increases residence time of positively-charged macromolecules and decreases residence time of negatively-charged macromolecules. Through our approach, ColHA hydrogels serve as a platform for the systematic evaluation of therapeutic macromolecule transport as a function of molecular characteristics.

Why Do So Many People with Type 2 Diabetes Who Take Insulin Have Lipohypertrophy? Fate or Educational Deficiencies? Diabetes Ther 2023; 14:179-191. [PMID: 36472805 PMCID: PMC9735184 DOI: 10.1007/s13300-022-01341-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 11/07/2022] [Indexed: 12/12/2022] Open
Abstract
INTRODUCTION Cutaneous lipohypertrophy (LH) is a thickened, "rubbery" lesion in the subcutaneous tissue following multiple injections performed at the same site, i.e., an incorrect injection technique. It is widespread, averaging 47% of insulin patients worldwide, and has severe direct and indirect consequences. Direct consequences consist mainly of poor metabolic control and frequent hypoglycemic events (HYPOs), and indirect ones of markedly increased healthcare costs related to hospital access due to acute events and long-term disease complications. This observation also holds for Italy, despite the National Health System organization expecting every patient with diabetes to undergo a series of visits by different care team members, each performing a specific treatment/education task. Indeed, the recent literature points to poor awareness of LH relevance and metabolic consequences among doctors from general and diabetic hospital wards, with educational deficiencies on correct injection practice in nurses too. The aim was to establish if, to what extent, and by whom they had received training on correct insulin injection techniques, and how many initially received notions had persisted over time. METHODS We investigated the possible causes of such a failure from the point of view of 1160 insulin-requiring subjects with type 2 diabetes (T2DM), reporting for the first time to specialized diabetic structures through a validated questionnaire and, in the same patients, we searched for LH by inspection/palpation according to international guidelines, further confirmed by ultrasound scans. We then analyzed differences in education and injecting behavior between subjects classified as LH+ or LH- depending on the presence or absence of LH lesions. RESULTS We documented significant educational gaps, with 50% of patients failing to refer to healthcare professionals and relying on their peers with diabetes, thought to be more experienced in 15% of the cases. Seventy-five percent of LH- patients received education from healthcare providers, while 90% of LH+ learned from another patient or could not remember how they knew, and 68% of LH+ versus 52% of LH- (p < 0.01) patients had failed to receive training on injection techniques by healthcare providers. All of this enabled the most disabling features of diabetes from the very beginning of the disease history. CONCLUSIONS This study documents, from the patients' point of view, that educational gaps are significant and that, even in initially trained subjects, education on correct injection techniques has a fleeting effect if not regularly recalled. Therefore, to rehabilitate LH+ patients as soon as possible and prevent LH- patients from inadvertently slipping into the other group, there is an urgent need to educate doctors and nurses repeatedly on the importance of correctly injecting insulin to improve patients' knowledge and skills.

Abstract
Lipodystrophy is the most common dermatological complication in patients with diabetes on insulin therapy. Despite the high frequency of lipodystrophy, there are still several difficulties in giving advice about avoidance into practice among children and adolescents with type 1 diabetes and their caregivers. This cross-sectional study aims to evaluate the prevalence of insulin-induced lipodystrophy in a cohort of pediatric patients with type 1 diabetes, to identify associated clinical factors and to assess its influence on glycemic control. Two hundred and twelve patients attending our Diabetes Center during a three-month period were enrolled. The presence of lipodystrophy was assessed by inspection and palpation procedures. Demographic and clinical data including type of treatment, frequency of rotation of insulin administration sites, and glucose metrics of the previous 30 days were assessed and statistically analyzed. Prevalence of lipohypertrophy was 44.3%. Two patients were affected by lipoatrophy (0.9%). Improper rotation of insulin administration sites and low awareness on lipodystrophy were associated to the occurrence of this skin condition (p = 0.050 and p = 0.005, respectively). When comparing patients with and without lipodystrophy, a significant difference in glycemic variability parameters was detected (p = 0.036 for coefficient of variation, p = 0.029 for standard deviation score of glucose levels). Lipodystrophy still represents a common complication in patients on insulin therapy. The present study reveals its negative impact on glycemic variability. This finding emphasizes the importance of prevention strategies to minimize the occurrence of this dermatological complication that may interfere with clinical history of the disease.

Abstract
BACKGROUND The most common dermatological complication of insulin therapy is lipohypertrophy. OBJECTIVE As a proof-of-concept, we built and tested an automated model using a convolutional neural network (CNN) to detect the presence of lipohypertrophy in ultrasound images. METHODS Ultrasound images were obtained in a blinded fashion using a portable GE LOGIQe machine with an L8-18i-D probe (5-18 MHz; GE Healthcare, Frankfurt, Germany). The data was split into train, validation and test splits of 70%, 15%, and 15% respectively. Given the small size of the dataset, image augmentation techniques were used to expand the size of the training set and improve the model's generalizability. To compare the performance of the different architectures, the team considered the accuracy and recall of the models when tested on our test set. RESULTS The DenseNet CNN architecture was found to have the highest accuracy (76%) and recall (76%) in detecting lipohypertrophy in ultrasound images, when compared to other CNN architectures. Additional work showed that the YOLOv5m object detection model could be used to help identify the approximate location of lipohypertrophy in ultrasound images identified as containing lipohypertrophy by the DenseNet CNN. CONCLUSIONS We were able to demonstrate the ability of machine learning approaches to automate the process of detecting and locating lipohypertrophy. CLINICALTRIAL

Abstract
BACKGROUND Lipohypertrophy (LHT) has been suggested as an outcome of the adipogenic effects of insulin injection-related tissue trauma. It commonly occurs in the clinical setting, but the current understanding of LHT by the medical staff and diabetes patients remains insufficient; moreover, it has not garnered attention as a research topic. OBJECTIVE To investigate the ultrasound characterization of LHT, to identify the factors associated with LHT development by assessing the prevalence of LHT and compare the accuracy of clinical palpation with that of ultrasonography in LHT detection, and to further evaluate the possible impact of LHT on patients' blood glucose fluctuations. METHOD A cross-sectional study was conducted in 120 patients with type 2 diabetes. Patients' general information were obtained using a questionnaire, and the patients were evaluated for LHT by ultrasonography and clinical palpation of the abdomen. The patients were instructed to inject equal amounts of insulin in tissues with LHT and in normal adipose tissues (NATs) in two non-consecutive d in a selected week; the possible effect of LHT on patients' blood glucose fluctuations was assessed using a continuous glucose monitoring system. RESULTS LHT has characteristic ultrasonic signs. We found a high rate of missed LHT detection on clinical palpation compared with that on ultrasonography (P < 0.05). The duration of insulin treatment, rotation of injection sites, frequency of needle reuse, and number of insulin injections per day were the primary factors influencing the development of LHT (P < 0.05). Compared with NATs, LHT tissues showed extremely elevated amplitude of glycemic excursion, mean blood glucose levels, standard deviation of blood glucose levels and postprandial glucose excursion, and large fluctuations in blood glucose levels (P < 0.05). CONCLUSION Ultrasonography can more accurately detect LHT than can clinical palpation. LHT development is associated with several factors and can lead to significant fluctuations in blood glucose levels; thus, sufficient attention should be paid to investigating the underlying mechanism of LHT.

Abstract
Aims/Introduction Subcutaneous dystrophic tissue (DT) produced by insulin injection causes dysglycemia owing to inadequate absorption of insulin. However, precise techniques for measuring DT have not been established. Shear wave elastography (SWE) is an imaging technology that can quantify tissue stiffness. In this study, insulin injection‐induced DT was quantified using SWE to generate whole‐abdominal wall subcutaneous tissue by three‐dimensional (3D) imaging in patients with type 2 diabetes who were treated with multiple insulin injections. Materials and Methods Seven patients with type 2 diabetes were recruited who received long‐standing multiple insulin injections. Using SWE, the shear wave velocity (SWV) of DT and control (normal subcutaneous tissue) was measured. Furthermore, two of seven patients underwent whole‐abdominal SWE examination to calculate the proportion of DT. A subcutaneous insulin tolerance test was also performed in both the DT and control tissues. Results The SWV in DT was significantly higher than that in the control tissue (2.87 [2.66–2.98] vs 1.29 [1.23–1.44] m/s, P < 0.01). The proportion of the DT volume was 0.67% and 5.21% for two individuals from the entire abdominal subcutaneous tissue volume. The area under the curve for the subcutaneously injected insulin aspart concentration at the DT sites was lower than that of the control tissue (75.0 [52.1–111] vs 116 [86.9–152.5] h*mU/L, P = 0.1). Conclusions SWE can be useful in quantifying abdominal subcutaneous insulin‐induced DT, especially the 3D volume of insulin injection‐induced DT from the entire abdominal subcutaneous tissue. This study is the first to examine the volume and distribution of abdominal subcutaneous DT using SWE.

Abstract
AIMS To investigate whether single use of 4 mm needles combined with education about injection technique and lipohypertrophy affects HbA1c, hypoglycaemia and glucose variability. METHODS Insulin-injecting people with diabetes recruited from nine Belgian diabetes centres were prospectively followed for 6 months. They were provided 4 mm pen needles and education concerning injection technique using an online platform (BD and Me™) based on the international Forum for Injection Technique & Therapy Recommendations focused on avoidance of lipohypertrophy zones and reduction of needle reuse. RESULTS A total of 171 people with diabetes were included of which 146 completed the study. At baseline, lipohypertrophy was present in 63.0% of those who completed the study, with 51.4% injecting in zones of lipohypertrophy, 37.0% incorrectly rotating and 95.9% reusing needles. After the intervention, 7.5% still injected in a lipohypertrophy zone, 4.1% rotated incorrectly and needle reuse decreased to 21.2%. The number of participants with severe hypoglycaemias (from 15.8% to 4.1%, p < 0.001), unexplained hypoglycaemias (from 46.6% to 16.4%, p < 0.001) and high glucose variability (from 64.4% to 29.5%, p < 0.001) was significantly reduced. HbA1c and total daily insulin dose remained stable. CONCLUSION The combination of 4 mm pen needles and online education on injection techniques significantly reduced the number of people with severe hypoglycaemic episodes, unexplained hypoglycaemia and high glucose variability but did not improve HbA1c control nor lower insulin needs.

Abstract
Background: It is important that physicians be aware of LH. We designed a questionnaire to determine physician awareness, knowledge, and behaviors regarding LH in clinical practice. Participants: A total of 499 questionnaires were completed by physicians in hospitals from 13 cities in Jiangsu Province, China. Key Results: Compared with physicians at tertiary hospitals, significantly fewer physicians at primary hospitals reported awareness of LH and its screening methods. The proportion of resident physicians aware of LH was significantly lower than the proportion of senior physicians. The proportion of physicians who could identify all LH risk factors among the low-GDP group was significantly higher than the high-GDP group. Only 38.7% of doctors could successfully identify all the hazards associated with LH, but more doctors in tertiary hospitals were able to do so compared to those in secondary and primary hospitals. Compared with tertiary hospitals, the proportions of primary and secondary hospitals with management processes were significantly lower. The proportion of doctors who educated patients regarding LH prevention and treatment in primary hospitals was markedly lower than in tertiary hospitals. Conclusions: Overall, physicians have an inadequate understanding of LH, especially in primary hospitals.

Abstract
INTRODUCTION Lipohypertrophy is a common complication of exposure to insulin therapy. Despite the prevalence of lipohypertrophy and its potentially hazardous effects on glucose regulation, it remains a relatively understudied problem in diabetes. The objective of this study was to characterize lipohypertrophic tissue using ultrasound in adults with type 1 diabetes. RESEARCH DESIGN AND METHODS An observational study of 74 people with type 1 diabetes from a diabetes center in South East London. Participants' insulin exposed areas were scanned with ultrasound, with a high-frequency linear probe (6-13 MHz). The observed tissue changes were described, measured and graded according to nodule size and thickness of the dermal layer. RESULTS Participants mean age and diabetes duration were 40.6 (±14.2) and 18.3 (±10.9) years, respectively, and 60% (n=44) were male. A total of 740 lipohypertrophic nodules were observed, ranging from 1.8 mm to 40 mm in width. The mean (SD/range) number of nodules per participants was 10.4 (±6.2/1-29). Delineation between the dermal layers was disrupted in all current injection sites. In 52 participants (70%), there was a 30% increase in dermal thickness compared with local none injected tissue, and in 36 participants (48%) the increase was 50%. The level of thickness was >3 mm in the abdominal areas of 22 (40%) of these participants and in thighs of eight participants (17.8%). Hypoechogenic areas suggestive of necrotic tissue were observed within the lipohypertrophic nodules of 22 (30%) participants. Needle length and nodule depth were correlated (r=0.69, p<0.001). A conceptual model of the insulin exposed tissue changes observed was constructed. CONCLUSIONS The study confirms that insulin-exposed tissue changes are heterogenous and has provided conceptual and grading frameworks for classifying these changes. Further studies are required to establish the clinical implications of these classifications, in relation to glucose regulation and other clinical parameters.

Abstract
The aim of this study was to explore the values of ultrasound for diagnosis and management of insulin-induced lipohypertrophy and further analyzing the impact of body mass index and subcutaneous fat thickness on ultrasound manifestations of lipohypertrophy.In this 3-month, prospective cohort study, a total of 162 patients with diabetes who used insulin therapy more than 1 year with unknown lipohypertrophy status were enrolled into this study. Demographic information, assessment of glycemic control and insulin injection technique were evaluated. Physical and ultrasound examination were separately performed to detect lipohypertrophy by a team of diabetes educator nurses or ultrasonographer in a blinded fashion. Patients with lipohypertrophy received insulin injection technique education based on ultrasound examination and Chinese guideline.Ultrasound examination detected 41.1% more patients (74.1% vs 52.5%; P < .001) with lipohypertrophy and 61.2% more lesions (216 vs 134; P < .001) than physical examination. Glycosylated hemoglobin A1c and fasting blood glucose were significantly decreased in patients with lipohypertrophy or subclinical lipohypertrophy (lipohypertrophy without visual and palpation changes) after receiving insulin injection technique education based on ultrasound examination and Chinese guideline than baseline at 3 months (P < .001). The proportion of lesions with ultrasound manifestation 2 (distortion of surrounding connective tissue) in obese and STF (>15 mm) groups were no more than 50% and showed a decreased trend with increased subcutaneous fat thickness and body mass index (P < .001).Lipohypertrophy has characteristic ultrasound manifestations which can detect more accurate results than palpation alone and provide detailed information to promote effective education on lipohypertrophy management, thereby improving glycemic control.

Abstract
Quantification of insulin is essential for diabetes research in general, and for the study of pancreatic β-cell function in particular. Herein, fluorescent single-walled carbon nanotubes (SWCNT) are used for the recognition and real-time quantification of insulin. Two approaches for rendering the SWCNT sensors for insulin are compared, using surface functionalization with either a natural insulin aptamer with known affinity to insulin, or a synthetic lipid-poly(ethylene glycol) (PEG) (C16 -PEG(2000Da)-Ceramide), both of which show a modulation of the emitted fluorescence in response to insulin. Although the PEGylated-lipid has no prior affinity to insulin, the response of C16 -PEG(2000Da)-Ceramide-SWCNTs to insulin is more stable and reproducible compared to the insulin aptamer-SWCNTs. The SWCNT sensors successfully detect insulin secreted by β-cells within the complex environment of the conditioned media. The insulin is quantified by comparing the SWCNTs fluorescence response to a standard calibration curve, and the results are found to be in agreement with an enzyme-linked immunosorbent assay. This novel analytical tool for real time quantification of insulin secreted by β-cells provides new opportunities for rapid assessment of β-cell function, with the ability to push forward many aspects of diabetes research.

Abstract
BACKGROUND Diabetes mellitus (DM) is the leading cause of end-stage renal disease and 50% of dialysis patients are insulin-treated. AIM to search for unexplained hypoglycemia (HYPO). METHODS identify a possible cause of HYPO due to altered insulin absorption. RESULTS insulin injected into subcutaneous lipo-hypertrophy (LH) nodules leads to unpredictable HYPOS. CONCLUSION looking for LH systematically and training patients to the best injection technique are new challenges for nephrologists to reduce HYPO and emergency hospitalization rates, thus sparing healthcare resources and improving the quality of life of insulin-treated dialysis patients.

Abstract
OBJECTIVE Insulin-induced lipodystrophy is of two types, lipohypertrophy and lipoatrophy. Lipodystrophy often leads to worsening of glycemic control in type 1 diabetes mellitus. Our objective was to identify the clinical, immunological, and other factor(s) associated with the development of lipodystrophy. METHODS In this observational cross-sectional hospital-based study, 95 children, adolescents, and young adults with type 1 diabetes mellitus were observed for the development of lipodystrophy. Injection technique, insulin dose, and glycemic parameters were noted. Serum TNF-α, IL-1β, and anti-insulin antibody levels were measured. Histopathological examination of the lipodystrophic area was done in a small number of people. RESULTS Among the participants, 45.2% of participants had lipohypertrophy and 4.2% had lipoatrophy exclusively; 3.1% of participants had coexisting lipohypertrophy and lipoatrophy. Improper injection site rotation technique was more common in participants with lipohypertrophy in comparison to those without lipodystrophy. The age of onset of diabetes, duration of insulin use, and the number of times of needle reuse were not significantly different between the lipohypertrophy and nonlipodystrophy groups. Serum TNF-α, IL-1β, and anti-insulin antibody levels; HbA1c; rate of hypoglycemia; and body weight-adjusted dose requirement were higher among the participants with lipohypertrophy. On histopathology, scant, or no inflammatory infiltrate was found in lipoatrophic and lipohypertrophic areas, respectively. CONCLUSION Improper insulin injection technique and higher levels of proinflammatory cytokines and anti-insulin antibody are associated with lipodystrophy in type 1 diabetes mellitus. HbA1c and rate of hypoglycemia are higher in people with lipodystrophy.

Abstract
Ultrasound is increasingly used in daily clinical practice to improve the efficiency of the clinical examination. In this article, we reviewed its various possible uses in the field of diabetology. The ultrasonic evaluation of the carotid arteries (plaques and intima media thickness) allows improving the assessment of the cardiovascular risk. Steatosis can be detected relatively easily on liver ultrasound. Ultrasound also allows a more sensitive detection of lipohypertrophy resulting in glycemic fluctuations and thus increasing the risk of hypoglycemia than the clinical examination. Finally, muscle ultrasound appears to be a promising tool to assess the nutritional status and its consequences (e.g., falls).

Abstract
INTRODUCTION Proper insulin injection technique has demonstrated positive clinical outcomes in patients with diabetes. A Canadian-based practice reflective was undertaken to evaluate the current state of understanding of injection technique practices by patients administering insulin, and the importance physicians place on proper injection technique. METHODS Twenty-four sites across Canada completed a practice profile survey and enrolled adult non-pregnant patients with either type 1 or type 2 diabetes injecting insulin using an insulin pen. Seven areas of proper injection technique to be evaluated were identified by the study steering committee: size of injection site, use of a skin lift, needle reuse, length of the needle, duration of the needle in the skin, injection into lipohypertrophic tissue, and applied injection force. During a scheduled visit, each patient filled out the Injection Technique Survey and the physician documented the answers via an electronic database. RESULTS Almost all physicians surveyed agreed (96%) that proper insulin injection technique is important or very important and 80% indicated they were either completely confident or fairly confident in discussing overall insulin injection technique. All patients surveyed were making at least one insulin injection technique error within the following categories: applied injection force (76%), area size of injection site (64%), duration of pen needle in skin (61%), pen needle reuse (39%), performs a skin lift with a 4 or 5 mm needle (38%), uses a longer pen needle than required (34%), and injection of insulin into lipohypertrophic tissue (37%). CONCLUSION Patients commonly make insulin injection errors. Patient and physician education on optimal insulin injection technique continues to be an unmet medical need for the treatment of patients with diabetes. Prospective trials examining the impact of new technology, diabetes educational teams, and e-learning as educational interventions are potential avenues to explore in future studies to support improved insulin injection technique.

To date, almost all case reports of insulin-derived amyloidosis described the presence of a subcutaneous mass that was observable on physical examination. This report presents two cases of insulin-derived amyloidosis without palpable masses at insulin injection sites. In both cases, blood glucose concentrations improved, and the insulin dose could be reduced by an average of 45% after changing the insulin injection sites. The insulin absorption at the site was reduced to at most 40% of that at a normal site in one case. Magnetic resonance imaging and ultrasonography were useful to screen and differentiate insulin-derived amyloidosis without a palpable mass. This report showed that insulin-derived amyloidosis without a palpable mass can be present at the insulin injection site, and has similar clinical effects to insulin-derived amyloidosis with palpable masses.

Abstract
Insulin infusion pump, continuous glucose monitoring (CGM), and insulin infusion set (IIS) have been developed to be increasingly feasible for people with type 1 diabetes (T1D). Several recently approved CGMs are transitioning from 7-day to 10-day wear time without the need for fingerprick recalibration. Nevertheless, studies and improvements on IIS, a critical part of insulin pump therapy, have been limited. In particular, the recommended wear time of IIS is still 2-3 days, which can hardly match the current duration of CGM for potential closed-loop system development. It is generally believed that both the inserted catheter and the subsequent infused insulin drug could induce particular subcutaneous tissue response and skin-related complications at the infusion site. In certain cases, poor glycaemic control, increased risk of hypoglycemia, and serious cosmetic impact on people with diabetes were observed. Skin complication has also been attributed as an important factor resulting users to discontinue insulin pump therapy. This article provides the rare systematic review of IIS induced subcutaneous tissue responses and skin complications, including the impacts from the inserted catheters, the subcutaneous infused insulin, and the adhesive or tape used to immobilize the catheter. The FDA's recommendation for the frequency of IIS change was further discussed. Future studies on this topic are required to further understand the IIS-related problems, and future strategies could be developed accordingly to significantly reduce the incidence of these problems, extend the wear time, and increase the acceptance of insulin pump based therapy.

Abstract
The efficacy of insulin therapy in diabetes depends on proper injection technique. Professional education can results in higher patients’ satisfaction. Proper insulin injection is important to good glycemic control.
Objective The aim of this study was to elucidate injection techniques, treatment satisfaction and glycemic control after education among patients with type 2 diabetes. Methods 4513 insulin-treated diabetic patients enrolled in the observational study EGIDA II (Education and GensuPen In Diabetology II) filled out the questionnaire which focused on key insulin injection parameters, pain sensation scale and satisfaction of the treatment form before (visit 1) and after 3 months treatment with insulin injection (visit 2). The education was performed by trained healthcare professionals. To assess the utility and comfort during using new automatic injection system (GensuPen) we separated 2 groups: A – treated with GensuPen and B – treated with other pens. Results The education resulted in increased number of patients who properly remix cloudy insulin; inject insulin into skin; change every time the injection site; use the pen needle only once; prepare a pen for injection and store insulin. We noticed significant decrease in BMI and sensation of pain in both groups. Our study revealed that patients’ satisfaction with the treatment increased with each of the 5 items (type of the treatment, mood, physical activity, vital energy, a sense of control over the disease) using a 5-point scale, with greater increase in group A. The utility and comfort (weight, thickness, easiness in remove pen cap, cleaning, twisting, keeping in hand the pen, dial the dose, readable signaling of injected dose) during using the GensuPen significantly increased in group A. Finally the mean glucose level in self-control diary was significantly lower after 3 months of the treatment in both groups, however the difference between visit 1 and 2 was greater in group A. Conclusion The study showed that proper selection of pen and professional education can result in the improvement of insulin injection technique, higher patients’ satisfaction and better glycemic control.

Abstract
BACKGROUND Lipodystrophy has been reported as a common complication in insulin-treated patients, which could lead to unexplained hypoglycemia and suboptimal glycemic control. This study aimed to determine the prevalence, associated risk factors, and clinical characteristics of insulin-induced lipodystrophy in Thai patients. PATIENTS AND METHODS This was a cross-sectional study involving insulin-treated patients at Theptarin Hospital, one of the largest diabetes centers in Thailand. RESULTS A total of 400 patients were studied (female 53.5%, T2DM 86%, mean age 65.6±15.4 years, duration of diabetes 23.0±10.2 years, median insulin treatment 10 years, usage of insulin analog 72.1%, A1C 7.9±1.6%) . The prevalence of lipohypertrophy (LH) in overall patients was 37.3% (T1DM 46.4% and T2DM 35.8%). The highest prevalence (57.5%) was observed in long-standing (≥10 years) T1DM patients. Multivariate analysis revealed that the duration of insulin use (≥10 years), use of human insulin, and incorrect rotation of injection sites were associated with LH. Patients with LH were found to have 7-times greater risk of unexplained hypoglycemia when compared with patients without LH. Lipoatrophy (LA) was found in only four cases (1.0%). All LA cases had a concurrence palpable area of LH. CONCLUSION Insulin-induced lipodystrophy is still an overlooked complication in the conundrum of diabetes care. The presence of lipodystrophy was significantly associated with the occurrence of unexplained hypoglycemia. It should be emphasized to recognize this condition by inspecting and palpating insulin injecting sites regularly, and educate patients to avoid the development of lipodystrophy.

Abstract
IN BRIEF To be consistently effective, insulin must be delivered into subcutaneous tissue. If insulin is delivered intramuscularly, its uptake and action become variably faster, leading to suboptimal, inconsistent glucose control. The best strategy to avoid intramuscular injection is to use the shortest needles available. Injection sites should be rotated systematically to prevent lipohypertrophy, which also substantially affects insulin uptake and action. New evidence-based insulin delivery recommendations are available, and awareness of them should lead to more effective use of insulin therapy, improved clinical outcomes, and considerable cost savings.

Abstract
Aim. To estimate clinical significance of lipohypertrophy (LH) without visual and palpable changes, detected by ultrasonography of subcutaneous fat. Materials and methods. This study included 140 diabetic patients who received insulin in basal-bolus regimen. Ultrasonography of subcutaneous fat was performed for LH diagnostics in these diabetic patients. Than clinical significance of LH without visual and palpable changes was estimated. HbA1c level, fasting and postprandial glucose, episodes of hypoglycemia, body mass index (BMI) and scheme of insulinotherapy were evaluated at the moment of LH, after 3 and 6 months in all patients. Results and discussion. After changing injection sites, good results were demonstrated by measuring glucose and HbA1c level. Thus fasting glucose decreased from 9.03±1.98 mmol/l to 7.11±0.95 mmol/l (p=0.023). Postprandial glucose reduced from 10.27±2.72 mmol/l to 9.34±1.21 mmol/l (p=0.011). HbA1c level reduced from 9.27±1.75% to 7.43±1.02% (p=0.002). Also BMI decreased from 33.75±3.49 kg/m2 to 30.5±2.96 kg/m2 (p=0.018). Conclusion. LH without visual and palpable changes could worsen compensation of glycemic control and leads to hypoglycemia and chronic Somogyi rebound. So, LH without visual and palpable is as important and clinically significant as classic LH.

Abstract
Insulin-derived amyloidoma, also called an insulin ball, is a skin-related complication of insulin therapy caused by repeated insulin injections at the same site, where native folded insulin changes into amyloid fibrils and forms a mass with a granulomatous reaction. Insulin-derived amyloidoma is a clinically important condition because of its association with subcutaneous insulin resistance, but the precise effect and mechanism of the insulin absorption impairment have not been clarified. We generated insulin-derived amyloidomas in mouse skin, with the amyloidomas large enough to perform insulin tolerance tests in the mass by repeated injections of highly concentrated insulin amyloid fibrils. We demonstrated that the insulin-derived amyloidomas inhibit insulin absorption. By simultaneous administration of insulin and insulin amyloid fibrils, we showed that this effect is due to the amyloid fibril itself in the absence of a granulomatous reaction. In vitro studies revealed that insulin amyloid fibrils have extremely strong adhesion to native human insulin and various insulin analogs. Furthermore, we showed that native insulin that had adhered to insulin amyloid forms amyloid fibrils at physiological pH. These results suggest that the extreme adhesion of insulin amyloid to native insulin is the main mechanism of impaired insulin absorption and amyloidoma growth.

Abstract
Inappropriate injection technique leads to incorrect insulin dosing, increased pain and impaired glucose control in patients with diabetes. This review examines in detail the results of two clinical studies, the Glycemic Impact of Insulin Injection Technique (GIIIT) and the UK Lipo Study (UKLS) that examined the effect of teaching patients proper injection techniques to achieve good glycemic control.
The GIIIT study included patients with type 1 and type 2 diabetes (1870 years) who were on a regimen of multiple daily insulin injections. They were categorised into three groups: those that received structured injection technique training using 4-mm injection needles (TN), those that received injection technique training (T) and control (C). The UKLS study included 75 patients who received structured training to reduce the risk of developing lipohypertrophy.
Initially, deviations from proper insulin injection technique were observed in a majority of patients in both the studies. In the GIIIT study, 6 months after training under TN and T conditions, HbA1c decreased by 1%, with no observable changes under the C condition. The daily insulin dose was increased by 6 IU in all conditions. Overall, the use of 4-mm short needles reduced post-injective pain in all patients. In the UKLS study, for 6 months, the variability of glycemia and frequency of unexplained hypoglycaemia decreased as the daily dose of insulin decreased by an average 6 IU; in addition, HbA1c level decreased from 8.6% to 8.2%. Six months after the training, both studies noted a decrease in or disappearance of lipohypertrophy in the patients.
These results indicate that proper injection technique training improves glycemic control in patients with diabetes.

Abstract
AIMS To define standard criteria for the detection of lipohypertrophy using ultrasonography and to determine the accuracy of this method. METHOD Individuals using insulin therapy for ≥2 years with unknown lipohypertrophy status were enrolled at a diabetes education centre. A team of diabetes educator nurses performed a clinical examination for evidence of lipohypertrophy and a separate team of ultrasonographers examined participants in a blinded fashion. RESULTS The echo signature for lipohypertrophy consisted of location in the subcutaneous layer and lesions that were 1) well circumscribed either by hyperechoic foci with defined borders or a nodular shape with a hypoechoic halo, 2) heterogeneous in echotexture compared with surrounding tissue, 3) associated with distortion of surrounding connective tissue with 4) absence of vascularity and 5) absence of capsule. Ultrasonography identified individuals with lipohypertrophy significantly more frequently than inspection or palpation (P<0.0001). Inter-observer agreement was moderate (κ=0.50) and limited by the presence of subclinical lesions in 73% of the participants. CONCLUSIONS The ultrasound detection of lipohypertrophy is consistent with clinical examination and is reproducible using a defined echo signature. (ClinicalTrials.gov registration no: NCT02348099).

Abstract
INTRODUCTION Lipohypertrophy (LH) is a common complication occurring in diabetes individuals. The most common methods used include palpation, visual examination and/or ultrasound (US). To date, there is limited information on the detection sensitivity among the different techniques used to identify LH. This systematic review aimed to identify studies that examined insulin-related LH using US detection to identify the prevalence, characteristics and morphology of LH, and to compare US and clinical palpation methods for detecting LH. METHODS Three electronic databases were systematically searched for studies detecting LH using US in insulin users. Articles were screened for eligibility and included studies were appraised using quality assessment tools. The quality of the evidence was evaluated using Grading of Recommendations Assessment, Development and Evaluation, and the extracted data was synthesised narratively. RESULTS Sixteen articles were included in the review providing data on 1722 patients. The prevalence of LH prevalence varied from 14.5% to 88% (median 56.6%). Identified risk factors for the development of included insulin injection behaviour such as a lack of injection site rotation and social factors such as low education level. Four studies compared LH detection by US to palpation, providing inconsistent results. One study showed that palpation detected 64% more LH, whilst two studies demonstrated that US identified 50% more sites and extended areas of LH (additional ~ 5 cm2). Another study provided comparable estimates between palpation and US in clinicians trained to detect LH (97%). CONCLUSION The evidence highlights a lack of congruence in results pertaining to the detection sensitivity of US and palpation for LH sites. More research with robust study design is needed to verify whether clinically palpation is sufficient to detect LH, or whether US would increase the precision of LH assessment to help address this common clinically significant problem.

Abstract
INTRODUCTION Using the Turkish and rest of world (ROW) Injection Technique Questionnaire (ITQ) data we address key insulin injection complications. METHODS Summarized in first ITQ paper. RESULTS Nearly one-third of Turkish insulin users described lesions consistent with lipohypertrophy (LH) at their injection sites and 27.4% were found to have LH by the examining nurse (using visual inspection and palpation). LH lesions in the abdomen and thigh of Turkish patients are slightly smaller than those measured in ROW but more than half of Turkish patients who have LH continue to inject into them at least daily. More than a quarter of Turkish patients have frequent unexplained hypoglycemia and nearly 2 out of 5 have glycemic variability, both of which have been linked to the presence of LH and the habit of injecting into it. Nearly half of Turkish injectors report having pain on injection. Of these, just over half report having painful injections only several times a month or year (i.e., not with every injection). In Turkey the diabetes nurse has by far the major role in teaching patients how to inject. Nearly 40% of Turkish injectors get their sites checked at least annually, and a larger proportion than ROW had received recent (within the last 12 months) instruction on how to inject properly. CONCLUSION Turkish patients and professionals have clearly made progress in injection technique, but there are still considerable challenges ahead which the new Turkish guidelines will help address.

Abstract
BACKGROUND Lipohypertrophy (LH) at insulin injection sites is a common but preventable complication in type 1 diabetes mellitus (T1DM). We evaluated the prevalence, contributing risk factors, and consequences of LH, specifically the glycemic variability (GV) among T1DM patients. METHODS This is a cross-sectional study conducted at a tertiary care center in India, wherein 139 subjects with T1DM were randomly selected and evaluated for the presence of LH through visual and palpation examinations. Demography, anthropometry, and injecting practices were evaluated using a validated questionnaire and their effect on LH was determined. Subsequently, the effect of LH on GV and unexplained hypoglycemia (UH) was studied. Mean glucose, mean amplitude of glycemic excursions (MAGEs), and continuous overlapping net glycemic action (CONGA) were assessed in a subset of patients who injected insulin alternately in LH and non-LH sites. RESULTS The overall prevalence of LH was 69.8%, and was significantly higher in adults than in children (P = 0.038). Improper rotation of sites (P < 0.0001) and insulin syringe reusage for more than five times (P = 0.009) significantly increase the risk of LH. The presence of LH has a significant effect on GV and UH with adjusted odds ratios of 17.65 (P < 0.0001) and 28.02 (P < 0.0001), respectively. Ambulatory glucose monitoring on a subset of patients confirmed that the mean glucose, MAGE, and CONGA were higher when subjects injected insulin at LH sites than at non-LH sites. CONCLUSIONS Improper rotation of sites and reuse of needles are the leading causes of LH in Indian T1DM patients, which, in turn, significantly increases the risk of GV and UH.

Abstract
Introduction: As well as its negative effect on the subcutaneous tissues, lipohypertrophy has negative effects on clinical data. The purpose of this study was to examine the frequency of lipohypertrophy, risk factors and perceived barriers preventing rotation in individuals with type 2 diabetes.
Methods: This descriptive cross-sectional study was conducted at Diabetes Education Center and Endocrine and Metabolism Clinic of a university hospital and Diabetes Education and Monitoring Center in a private hospital in Turkey between June 2016- April 2017. The inclusion criteria were as follows; undergoing at least one year of insulin therapy, injecting insulin pens or syringes themselves, being over 18 years of age, making regular injection of insulin and being a patient with type 2 diabetes. Introductory information form was used to collect the data. The data were analyzed using descriptive statistics and chi-square analysis with SPSS version 16.0.
Results: Factors influencing lipohypertrophy development were determined as follows; healthcare personnel who provide insulin education, duration of diabetes, the number of injection administered daily, needle length, the number of injection sites, insulin types, injection site rotation and intra-site rotation and needle exchange frequency. In addition, the prevalence of lipohypertrophy was found to be higher in patients with hypoglycemia, unexplained hypoglycemia, and those with high BMI and A1C.
Conclusion: It is recommended that diabetes education should be provided by the diabetes specialist nurses who have diabetes-specific certifications and / or education and who can provide full-time education. Randomized controlled interventional studies investigating how to prevent the lipohypertrophy development are also needed.

Abstract
Background Pen needles are an important component of insulin delivery among patients with diabetes, but are not universally covered in China. We compared clinical and economic characteristics of insulin-dependent patients in China who have some level of pen needle (PN) reimbursement to those with no PN reimbursement. Methods A cross-sectional study was conducted among 400 insulin users with Type 1 or Type 2 diabetes treated in outpatient endocrinology units of four large tertiary care hospitals in Nanjing, Chongqing, Beijing and Zhengzhou. Demographics, medical history, healthcare resource utilization (RU), out-of-pocket costs, insurance and PN reimbursement status were surveyed. Unit costs were assigned to healthcare RU and compared using descriptive statistics and multivariate regression models. Results A total of 400 patients were analyzed; 142 (35.5%) with some level of PN coverage/reimbursement and 258 (64.5%) without. Patients without PN reimbursement had a higher prevalence of lipohypertrophy (59.3% vs. 40.7%, p = 0.0007), greater median PN reuse (12 vs. 7 times per needle, p < 0.0001), greater 6-month insulin costs (1591 vs. 1328 Renminbi [RMB], p = 0.0025) and total unadjusted 6-month expenditures (6433 vs. 4432 RMB, p < 0.0001), respectively. After controlling for clinical and demographic characteristics, patients without PN reimbursement had 4.6 times greater odds of high costs compared to those with PN reimbursement. Conclusions Insulin users without PN reimbursement may pose a greater economic burden to China compared to those with PN reimbursement. Expansion of insurance coverage for insulin PNs can improve the quality of care and potentially help reduce the economic burden in this population.

Abstract
Variability in the effect of subcutaneously administered insulin represents a major challenge in insulin therapy where precise dosing is required in order to achieve targeted glucose levels. Since this variability is largely influenced by the absorption of insulin, a deeper understanding of the factors affecting the absorption of insulin from the subcutaneous tissue is necessary in order to improve glycaemic control and the long-term prognosis in people with diabetes. These factors can be related to either the insulin preparation, the injection site/patient, or the injection technique. This review highlights the factors affecting insulin absorption with special attention on the physiological factors at the injection site. In addition, it also provides a detailed description of the insulin absorption process and the various modifications to this process that have been utilized by the different insulin preparations available.

Abstract
Lipohypertrophy has been suggested as an outcome of lipogenic action of insulin and/or injection-related tissue trauma. In a cross-sectional study, we evaluated the predictors of lipohypertrophy in 372 type 1 diabetes patients (mean age 17.1 years) receiving subcutaneous insulin with pen and/or syringes for ≥3 months. On examining injection sites with inspection and palpation technique, 62.1% patients demonstrated lipohypertrophy. Univariate analysis showed that gender, BMI, HbA1c, injection device, rotation, injection area, needle length, insulin regimen, and total daily dose of insulin were associated with lipohypertrophy (p < 0.05). Notably, the mean needle reuse was comparable in patients with or without lipohypertrophy (8.1 vs. 7.2, p = 0.534). In multivariate logistic regression, gender, HbA1c, TDD, injection devices, and needle length lost its significance. Further, injections over smaller area (≤8.5 × 5.5 cm) and non-rotation of sites were found to be strongest independent predictor of lipohypertrophy (p < 0.0005 for both) with increased odds of 23.2 (95% CI 9.1-59.2) and 6.3 (95% CI 3.4-11.9) times, respectively. Being underweight was also a significant independent predictor (odds ratio [OR] 13.0 [95% CI 2.2-75.2], p = 0.004). Compared to rapid plus long-acting analogs, regular insulin plus long-acting analogs and conventional premixed insulin users had 3.2 (95% CI 1.5-6.8, p = 0.003) and 4.6 (95% CI 1.4-15.7, p = 0.014) fold higher risk of lipohypertrophy (mean injection frequency 4.01 vs. 4.01 vs. 2.09, respectively). Sub-group analysis showed that lipohypertrophy was 79% less likely in patients with multiple daily injections (≥4) than twice-daily regimen (OR 0.21, p < 0.0005). Moreover, lipohypertrophy was reduced to half with bolus doses of rapid-acting insulin analogs than regular insulin (p = 0.003), even though mean injection frequency was comparable (4.01 vs. 3.93, p = 0.229). This difference was statistically insignificant for basal doses with NPH or long-acting analogs (p = 0.069). Therefore, injection area, rotation, BMI, and insulin regimen are the best predictors of lipohypertrophy and together could correctly identify lipohypertrophy status in 84.4% patients with excellent discrimination capability (AUC = 0.906, p < 0.0005). In conclusion, findings of our study suggest that delivering rapidly absorbed insulin analogs over large injection area along with greater split of total daily doses reduce insulin-induced lipogenesis and outplay tissue trauma added through frequent injections and needle reuse.

Abstract
AIMS Lipohypertrophy (LH) represents the most common skin-related complication associated with insulin therapy. Our aim is to estimate the prevalence of LH among insulin-treated patients, to identify its association with errors in insulin injection technique and storage, and the correlation between LH, risk of hypoglycemia, and glycemic control. METHODS Consecutive patients with T1DM or T2DM, attending a diabetes clinic for a routine visit, were administered an anonymous questionnaire investigating the modalities of insulin injection, the correct use of pen device, insulin storage, and reported frequency of hypoglycemic episodes. The presence of LH was assessed by inspection and palpation of injection sites. RESULTS Overall, 352 patients were enrolled (mean age 68 ± 12 years, 43.2% males, 88.9% with T2DM, mean duration of insulin therapy 9.1 ± 8.6 years). The prevalence of LH was 42.9%. At multivariate analysis, the strongest correlates of LH were not spacing injections (OR 20.4; 95% CI 10.5-39.6) and not rotating the site of injection (OR 2.01; 95% CI 1.08-3.75). Increasing doses of insulin and longer duration of insulin therapy also increased the risk of LH. The presence of LH was associated with a 2.7 times higher risk of severe hypoglycemia. Higher daily insulin doses, lack of rotation of injection sites, and keeping insulin in use in the refrigerator were independent correlates of higher HbA1c levels. CONCLUSIONS Insulin injection technique is suboptimal in many patients, highlighting the need for improved patient education. Increasing the awareness of the importance of preventing lipohypertrophy and insulin injection errors represents an important tool to reduce the clinical, social, and economic burden of diabetes.

Abstract
INTRODUCTION Improper injection technique can negatively affect glycemic control and treatment tolerability. We assessed the impact of structured insulin injection training on glycemic control. METHODS We compared changes in glycated hemoglobin (A1C) and fasting plasma glucose following structured insulin injection training in a 6-month pilot study in patients with type 1 or 2 diabetes. Patients were recruited from mobile clinics in Moscow, Russia, and randomized into three groups. Groups 1 and 2 received structured injection training, and group 3 did not. Group 1 received 4-mm needles sufficient for each injection; groups 2 and 3 provided their own needle supply. Changes in insulin total daily dose (TDD), injection technique, needle reuse, and lipohypertrophy (LH) were assessed. RESULTS Of 120 patients enrolled, 116 were included in all analyses (group 1, n = 43; group 2, n = 35; group 3, n = 38). At 6 months, mean [95% CI] reductions in A1C were significant in groups 1 and 2 (- 1.00% [10.9 mmol/mol (- 1.3 to - 0.6)] and - 1.00% [10.9 mmol/mol (- 1.4 to - 0.7)], respectively; P < 0.001 for both), but not in group 3 (- 0.02% [0.2 mmol/mol (- 1.2 to 1.6)]). Increases in insulin TDD, however, were similar and significant across groups (approximately 6 IU; P < 0.05). Injection technique improved, and needle reuse and LH declined in groups 1 and 2, but not in group 3. CONCLUSIONS Little is known about the glycemic impact of insulin injection training. We found that structured training and the use of short pen needles can improve injection technique, leading to significant A1C reductions and decreased rates of LH.

Abstract
OBJECTIVE Subcutaneous insulin absorption is one of the key factors affecting glycemic control in patients with diabetes mellitus under insulin therapy. Insulin-induced subcutaneous lipohypertrophy has been reported to impair insulin regular absorption and hence glycemic control. So far, lipohypertrophy diagnosis has only been clinical. This study aims at evaluating the possible role of ultrasound scan in the assessment of subcutaneous lipohypertrophy in patients affected by type 1 diabetes mellitus. METHODS A pilot observational retrospective study was performed in 20 patients affected by type 1 diabetes mellitus. In these patients the areas with clinical evidence of lipohypertrophy dependent on the insulin injections were characterized by the presence of tissues that at the ultrasound scan resulted similar to fibrotic tissues (hyperechogenic) or to an interstitial edema or to fat tissues (hypoechogenic). It was utilized a multi frequency linear probe (6-18 MHz). The patients were advised to avoid insulin injections on the areas with lipohypertrophy scanned by the ultrasound and the HbA1c changes were evaluated 3 months later. RESULTS The lipohypertrophic areas presented at least three different aspects upon ultrasound assessment: the iso-hyperechogenic one, with a predominant fibrotic component; the isoechogenic one, with "large tangles" fibrotic elements and the iso-hypoechogenic aspect with no fibrotic elements. When patients were advised to avoid insulin injections on areas with lipohypertrophy defined by ultrasound scan, 3 months after the first evaluation HbA1c had significantly improved (basal HbA1c 7.87 ± 0.56 versus 7.67 ± 0.52 3 months later, p = 0.029). No significant improvements of the HbA1c were found in the control matched group in which lipohypertrophy was only clinically valued through inspection and palpation. CONCLUSIONS Ultrasound scan can help identify and characterize the lipohypertrophic areas and this might be useful to improve glycemic control.

Abstract
La lipodistrofia (lipohipertrofia, lipoatrofia) es una complicación dada por la técnica inadecuada de inyección subcutánea de insulina. Se presenta el caso de una paciente de 46 años con diabetes mellitus tipo 2 descontrolada, en tratamiento con insulina glargina 45UI/día, sin control glucométrico y con múltiples ajustes y hospitalizaciones. Al ingreso, el automonitoreo muestra glucometrías basales y posprandiales fuera de metas, glucemia basal de 299 mg/dL y HbA1c de 11%. Al interrogatorio, se evidencian fallas en la técnica de aplicación de insulina, en particular falta de rotación del sitio de aplicación. En el examen físico se encuentra lipohipertrofia dada por panículo adiposo infraumbilical prominente bilateral e induración del tejido celular subcutáneo; en ecografía se visualiza infiltración grasa de rectos anteriores. Se da instrucción a la paciente sobre la correcta técnica de aplicación de insulina con rotación diaria del sitio de aplicación, descanso de zonas con lipohipertrofia y guía para automonitoreo.El automonitoreo en los 10 primeros días mostró mejoría de glucometrías basales hasta 116 mg/dL y valor limítrofe de 75 mg/dL, comparados con promedio de glucometría basal previa de 242 mg/dL con la misma insulina y dosis. Se hizo seguimiento estrecho para definir dosis requerida de insulina y vigilar posible hipoglucemia, con mejoría en la HbA1c de 9.2% y 8.8% a los 4 y 11 meses, respectivamente.

Abstract
INTRODUCTION Using the Indian and rest of world (ROW) injection technique questionnaire (ITQ) data, we address key insulin injection complications. METHODS In 2015 we conducted an ITQ survey throughout India involving 1011 patients. Indian values were compared with those from 41 other countries participating in the ITQ, known here as ROW. RESULTS More than a quarter of Indian insulin users described lesions consistent with lipohypertrophy (LH) at their injection sites and approximately 1 in 5 were found to have LH by the examining nurse (using visual inspection and palpation). Just over half of Indian injectors report having pain on injection. Of these, 4 out of 5 report having painful injections only several times a month or year (i.e., not with every injection). Doctors and diabetes educators in India (as opposed to nurses) have a larger role in teaching patients how to inject than they do in ROW. Despite this specialized approach, a very high percentage of patients report that they have not been trained (at least cannot remember being trained) in a wide range of essential injection topics. Only about 30% of Indian injectors get their sites checked at least annually, with nearly a third only having sites checked when they specifically complained and nearly 4 out of 10 never having had their sites checked. CONCLUSION Indian HCPs can clearly do a better job covering all the vital topics essential to proper injection habits.
