ANÁLISE ACERCA DO CONHECIMENTO DE GESTANTES E PUÉRPERAS SOBRE A IMPORTÂNCIA DA TRIAGEM NEONATAL EM UMA UNIDADE DE SAÚDE E SEUS IMPACTOS QUANDO NEGLIGENCIADA

Neonatal screening based on the “heel prick test” biological matrix is a fundamental test performed in newborns for the screening of genetic, metabolic, and infectious diseases that can lead to health problems or irreversible deficiencies if neglected. The heel prick test is a public health policy adopted in many countries, including Brazil, and is widely recognized as one of the most important procedures in preventive medicine, in order to guarantee comprehensive care and universal access. Thus, the National Neonatal Screening Program (PNTN) was created in 2001, to promote and implement screening actions with a special focus on prevention, early intervention, and monitoring of children whose disease is included in the program's criteria. It is necessary that the health team guide the pregnant woman during the prenatal period, and the puerperal women, as well as their respective companions, on how and where to perform the “heel prick test”, highlighting its purpose to ensure effective awareness. Therefore, the present study aims to analyze the level of knowledge about neonatal screening in pregnant and postpartum women in the public health network. As well as introduce them to the importance of tracking in a timely manner to manage positive cases through monitoring and follow-up during treatment.

12591 Screening For Metabolic Dysfunction-Associated Steatotic Liver Disease In Diabetes Clinics

Abstract Disclosure: D. D'Annibale: None. M. Mimoto: None. R. Lis: None. A. Deioma: None. H. Patton: None. Screening for Metabolic Dysfunction-Associated Steatotic Liver Disease in Diabetes Clinics Background: The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) in patients with Type 1 (T1D) or Type 2 diabetes (T2D) is elevated, ranging from 22% in T1D to >55% in T2D. However, MASLD screening is not standard in diabetes clinics. The Fibrosis-4 (FIB-4) score and transient elastography (TE) are non-invasive tools to identify those at risk for MASLD and liver fibrosis. To identify at-risk individuals and determine the prevalence of undiagnosed MASLD in our Veterans with diabetes and elevated BMI, we developed a screening protocol using FIB-4 and TE. Methods: Veterans with T1D or T2D and elevated BMI seen in diabetes clinic were prospectively screened. Patients with prior TE or liver disease were excluded. In phase 1, patients were offered in-clinic TE during their visit. In phase 2, a FIB-4 determined referral to TE or hepatology. Results: 274 patients were screened over 8 months. Of 102 qualifying patients in phase 1, 28 had in-clinic TE; of these, 7 (25%) had a kPa of 8 or greater, indicating increased risk of fibrosis, and 16 (57.1%) had a CAP score >280, indicating severe steatosis.In phase 2, a FIB-4 was ordered in 157 qualifying patients. Of 110 completed tests, the FIB-4 was <1.3 (low risk), 1.3–2.6 (indeterminate risk) and >2.6 (high risk) in 61 (55.5%), 44 (40%) and 5 (4.5%), respectively. Patients were referred to TE (indeterminate) or hepatology (high risk). To date, 21 patients have undergone TE, 5 (23.8%) had a kPa of 8 or greater and 11 (52.4%) had a CAP score >280. Conclusions In Veterans with T1D or T2D and elevated BMI, both of our screening protocols identified those with severe steatosis (57.1% vs 52.4%) by TE at rates similar to those reported in the literature. Increased risk of fibrosis by TE was identified in ∼24-25% of our screened population. The high prevalence of undiagnosed MASLD in our Veteran population supports the need for screening in diabetes clinics. Increased provider awareness and point-of-care TE may increase access to screening and improve early diagnosis. Presentation: 6/2/2024

High bone fracture risk in a large modern cohort of liver transplant recipients.

Liver transplantation (LT) has historically been associated with a high prevalence of osteoporosis, but most of the available data date back to late 1990s-early 2000s with limited sample size. Our aim was to assess the prevalence of bone fragility fractures and contributing factors in a large modern cohort of liver transplant recipients. Retrospective study of 429 consecutive patients receiving liver transplantation from 1/1/2010 to 31/12/2015. Final cohort included 366 patients. Electronic radiological images (lateral views of spine X-rays or Scout CT abdominal scans) performed within 6months from LT, were blinded reviewed to screen for morphometric vertebral fractures. Symptomatic clinical fragility fractures were recorded from the medical records. Patients with fragility fractures in the cohort were 155/366 (42.3%), with no significant differences between sexes. Most sustained vertebral fractures (145/155, 93.5%), mild or moderate wedges, with severe fractures more frequently observed in women. Multiple vertebral fractures were common (41.3%). Fracture rates were similar across different etiologies of cirrhosis and independent of diabetes or glucocorticoids exposure. Kidney function was significantly worse in women with fractures. Independently of age, sex, alcohol use, eGFR, and etiology of liver disease, low BMI was significantly associated with an increased risk for fractures (adjusted OR 1.058, 95%CI 1.001-1.118, P = 0.046). Our study shows a considerable fracture burden in a large and modern cohort of liver transplant recipients. Given the very high prevalence of bone fractures, a metabolic bone disease screening should be implemented in patients awaiting liver transplantation.

An Australian Community-Based Metabolic Dysfunction-Associated Steatotic Liver Disease Care Pathway for People with Type 2 Diabetes: Barriers and Considerations.

Although clinical guidelines endorse screening for metabolic dysfunction-associated steatotic liver disease (MASLD) with advanced fibrosis in people with type 2 diabetes (T2D), the feasibility of and barriers and considerations relevant to implementing this approach in the community remain unclear. Sequential adults with T2D attending selected community clinics during 2021-2023 were invited to receive a "liver health check" (n=543). A further 95 participants were referred directly from their general practitioner (GP) or self-referred to the study. A total of 302 participants underwent a point of care assessment of hepatic steatosis and stiffness (FibroScan) and were advised to see their GP to discuss the results. "Template" letters containing key results, their interpretation and advice about management of cardiometabolic risk, patient follow-up and referral criteria, were sent to participants' GPs. Referral to a tertiary liver clinic was advised in GP letters for 45 (15%) participants with an increased risk of clinically significant fibrosis (liver stiffness measurement ≥8), 15 participants with 'red flags' (eg splenomegaly, thrombocytopenia) and 2 with unsuccessful FibroScan examinations. A referral from GPs to the liver clinic was received for 27 (44%) of these 62 participants. Approximately 90% of GPs rated the "template" letters favourably on a Likert rating scale. The low rate of participation in the "liver health check" and liver clinic referral reflects a real-world scenario and may stem from societal under-recognition and engagement with MASLD, competing health priorities or under-appreciation of the link between liver fibrosis severity and mortality risk. Further studies need to address strategies to enhance participation in liver health assessments and determine their impact on liver-related morbidity/mortality and overall survival.

Screening for metabolic dysfunction-associated fatty liver disease: Time to discard the emperor's clothes of normal liver enzymes?

Metabolic dysfunction-associated fatty liver disease (MAFLD) is the most prevalent chronic liver condition worldwide. Current liver enzyme-based screening methods have limitations that may missed diagnoses and treatment delays. Regarding Chen et al, the risk of developing MAFLD remains elevated even when alanine aminotransferase levels fall within the normal range. Therefore, there is an urgent need for advanced diagnostic techniques and updated algorithms to enhance the accuracy of MAFLD diagnosis and enable early intervention. This paper proposes two potential screening methods for identifying individuals who may be at risk of developing MAFLD: Lowering these thresholds and promoting the use of noninvasive liver fibrosis scores.

Association between cardiometabolic index and hepatic steatosis and liver fibrosis: a population-based study.

The cardiometabolic index (CMI) is a new type of obesity index that is based on a combination of lipid levels and abdominal obesity indicators. It is closely correlated with the occurrence of diabetes mellitus, atherosclerosis, hypertension, and other diseases, thus playing an important role in the screening of metabolic diseases. This is coupled with hepatic steatosis and fibrosis which are characterized by excessive liver fat deposition. The aim of this study was to investigate the possible association between CMI and hepatic steatosis and liver fibrosis. A cross-sectional investigation was conducted using the 2017-2020 National Health and Nutrition Examination Survey (NHANES) dataset to probe the relationship between CMI and hepatic steatosis and liver fibrosis, while multiple linear regression models were used to test the linear association between CMI and controlled attenuation parameter (CAP) and liver stiffness measurement (LSM). Smooth-fit curves and threshold effects analysis were used to describe the nonlinear relationships. Subgroup analyses were performed according to gender, age, body mass index (BMI), hypertension, diabetes, cardiovascular disease, and smoking status. A total of 3084 adults aged 18-80 years were included in this analysis, and after controlling for a variety of variables, there was a significant positive correlation between CMI and CAP [20.38 (16.27,24.49)]. When subgroups were analyzed, this positive correlation was found to be stronger in the female population than in the male (P for interaction = 0.0303). Furthermore, the association between CMI and CAP was nonlinear. Using multiple regression analysis, it was shown that the linear relationship between CMI and liver fibrosis was not significant [-0.09 (-0.47,0.29)]. The findings suggest that elevated CMI levels are associated with hepatic steatosis, but that CMI is not linked to liver fibrosis. Larger prospective investigations are needed to confirm our findings.

A rapid action plan to improve diagnosis and management of lipodystrophy syndromes.

Lipodystrophy syndromes are rare diseases that can present with a broad range of symptoms. Delays in diagnosis are common, which in turn, may predispose to the development of severe metabolic complications and end-organ damage. Many patients with lipodystrophy syndromes are only diagnosed after significant metabolic abnormalities arise. Prompt action by clinical teams may improve disease outcomes in lipodystrophy syndromes. The aim of the Rapid Action Plan is to serve as a set of recommendations from experts that can support clinicians with limited experience in lipodystrophy syndromes. The Rapid Action Plan was developed using insights gathered through a series of advisory meetings with clinical experts in lipodystrophy syndromes. A skeleton template was used to facilitate interviews. A consensus document was developed, reviewed, and approved by all experts. Lipodystrophy is a clinical diagnosis. The Rapid Action Plan discusses tools that can help diagnose lipodystrophy syndromes. The roles of clinical and family history, physical exam, patient and family member photos, routine blood tests, leptin levels, skinfold measurements, imaging studies, and genetic testing are explored. Additional topics such as communicating the diagnosis to the patients/families and patient referrals are covered. A set of recommendations regarding screening and monitoring for metabolic diseases and end-organ abnormalities is presented. Finally, the treatment of lipodystrophy syndromes is reviewed. The Rapid Action Plan may assist clinical teams with the prompt diagnosis and holistic work-up and management of patients with lipodystrophy syndromes, which may improve outcomes for patients with this rare disease.

Ефективна інтегрована програма неонатального скринінгу як сучасний напрям діагностики спадкових хвороб обміну речовин у дітей (огляд літератури)

Today’s challenges contribute to technological progress in various fields of medicine. The introduction of extended neonatal screening (ENS) for hereditary metabolic diseases (HMDs) became the basis for the revolution of modern diagnostic technologies. Tandem mass spectrometry (TMS) technology has become a real breakthrough in the laboratory diagnosis of a number of HMDs, with the help of which it is possible to quickly determine the concentrations of dozens of different metabolites in a minimum amount of biological material at the same time. Purpose - to summarize the literature data on the current state, progress, and prospects of extended neonatal screening for hereditary metabolic diseases. We retrospectively analyzed the data of modern medical literature on ENS programs and investigated the issues of genomics and metabolomics in the practice of screening for HMDs according to scientometric databases: GoogleScholar, NCBI Pubmed, Cochranelibrary. The historical aspects of the formation and application of such a method of modern laboratory diagnosis of HMDs as tandem mass spectrometry are considered separately. Data on the role of genomics and metabolomics in the practice of neonatal screening for inborn errors of metabolism are also presented. Since the identification of patients by performing ENS provides an opportunity to expand knowledge about the genesis, frequency, genotype/phenotype correlation, and thus preliminary diagnosis and treatment benefit both the health care system and society. Thanks to exome and genome sequencing technologies, detection of a wider range of diseases has become available. No conflict of interests was declared by the author.

Alanine aminotransferase elevation varies by ethnicity among Asian and Pacific Islander children with overweight or obesity.

Limited research on alanine aminotransferase (ALT) screening for metabolic dysfunction-associated steatotic liver disease (MASLD) among US Asian/Pacific Islander (PI) children necessitates investigation in this heterogeneous population. Examine ALT elevation among Asian/PI children with overweight or obesity. Elevated ALT prevalence (clinical threshold) and association with body mass index ≥85th percentile were compared among 18 402 Asian/PI and 25 376 non-Hispanic White (NHW) children aged 9-17 years using logistic regression. ALT elevation was more prevalent among Asian/PI (vs. NHW) males with overweight (4.0% vs. 2.7%), moderate (7.8% vs. 5.3%) and severe obesity (16.6% vs. 11.5%), and females with moderate (5.1% vs. 3.0%) and severe obesity (10.2% vs. 5.2%). Adjusted odds of elevated ALT were 1.6-fold and ~2-fold higher for Asian/PI (vs. NHW) males and females (with obesity), respectively. Filipino, Chinese and Southeast Asian males had 1.7-2.1-fold higher odds, but Native Hawaiian/PI (NHPI) and South Asian males did not significantly differ (vs. NHW). Filipina and Chinese females with obesity had >2-fold higher odds, Southeast and South Asian females did not differ and NHPI findings were mixed (vs. NHW). High elevated ALT prevalence among Asian/PI children with overweight and obesity emphasizes the need for MASLD risk assessment and examination of ethnic subgroups.

Osteoporosis and cement usage in total hip arthroplasty.

Cement usage in total hip arthroplasty (THA) is increasingly common. However, osteoporosis-related fracture risk in cemented vs uncemented THA patients is poorly characterized. We aim to analyze the usage of metabolic bone care and osteoporosis fracture risk in cemented vs uncemented THA patients using FRAX and radiographic bone measurements. Chart review on 250 THA patients was performed retrospectively. Demographics, FRAX scores, hip radiograph measurements, osteoporosis diagnosis, treatment and screening were compared between cemented and uncemented THA patients. Logistic regression model was used to analyze factors influencing cement usage. Cemented THA patients have significantly higher osteoporosis-related fracture risk as measured by FRAX major (20% vs 13%) and FRAX hip (8% vs 5%). There is no significant difference in osteoporosis treatment, vitamin D / calcium supplementation, or metabolic bone disease screening based on patients' cement status. Female sex and rheumatoid arthritis status significantly predict cement usage, but FRAX scores do not predict cement usage. Additionally, 50% (10/20) of patients with Dorr C classification were uncemented. Although some patients undergoing THA with high osteoporosis-related fracture risk were identified and cemented, some risk factors including poor proximal femur shape (by Dorr classification) and poor bone quality (as measured by FRAX score) were potentially overlooked. Cemented patients had an increased risk for fractures but did not receive appropriately increased osteoporosis screening or treatment. III.

Selective screening for inborn errors of metabolism using tandem mass spectrometry in West Kazakhstan children: study protocol.

To set the reference values of 51 metabolites in the child population, 750 healthy children will be included. The selective screening will be performed among 1,500 patients aged 1day to 18years with suspected hereditary metabolic disorders. The results of selective screening will be interpreted by comparison with the reference values established. Diagnosis will be based on clinical signs, blood levels of amino acids, acylcarnitines, succinylacetone, and urine levels of organic acids and tests for gene mutations. An assessment of 37 inborn errors of metabolism frequencies in high-risk children will be performed. The research will further develop the national as selective as expanded newborn screening programs. The study was registered in clinicaltrials. gov (https://www. gov/study/NCT05910151) on 16 June 2023.

Selective Screening for Inborn Errors of Metabolism Using Tandem Mass Spectrometry in Newborns of the West Kazakhstan: Pilot Study

Tandem mass spectrometry can detect and quantify many metabolites in a single blood spot to diagnose amino acid disorders, organic acids, fatty acid oxidation, and urea cycle disorders. The use of tandem mass spectrometry (MS/MS) is expanding for the implementation of newborn screening programs for inborn errors of metabolism and for selective screening of children of different ages. In Kazakhstan, the use of MS/MS in metabolic screening programs is not yet developed due to the high cost of equipment and consumables and the lack of special screening centers and specialists. Data on the prevalence of most inborn errors of metabolism in Kazakhstan are not presented in the literature. Aim: to perform selective screening for hereditary metabolic diseases among newborns in western Kazakhstan using the liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Methods: Selective screening was performed among 250 newborns with suspected hereditary metabolic disorders using tandem mass spectrometry. Results: The results of selective newborn screening were interpreted by comparison with reference values established for this group. Diagnosis was based on clinical signs, blood levels of amino acids, acylcarnitines, succinylacetone, urine organic acids, and gene mutation tests. An assessment of 37 inborn errors of metabolism frequencies in high-risk newborns was performed. Conclusion: The research will further develop the national as selective as expanded newborn screening programs.

Long-Term Management of Patients with Mild Urea Cycle Disorders Identified through the Newborn Screening: An Expert Opinion for Clinical Practice.

Urea cycle disorders (UCDs) are a group of rare inborn errors of metabolism caused by a deficiency in one of the six enzymes or one of the two transporters involved in the urea cycle. Current guidelines suggest that early diagnosis and treatment of mild UCDs may improve survival and prevent decompensation and neurocognitive impairment. Nevertheless, clinical studies are very difficult to carry out in this setting due to the rarity of the diseases, and high-level evidence is scant and insufficient to draw conclusions and provide clinical guidelines. With the early introduction of newborn screening, the Italian healthcare organization fostered an advancement in expertise in metabolic disease management and screening programs, by allocating resources, and favoring the expansion of newborn screening. A group of experts operating in Italian centers decided to share their experience and provide advice for the management of mild UCDs in clinical practice. A consensus was reached by the Estimate-Talk-Estimate (ETE) method. Five items were identified, and statements for each item were agreed. Briefly, the panel advised completing the diagnosis by expanded newborn screening (ENS) with biochemical and genetic confirmation and by following up with the patient during the first year of life, with a routine laboratory and metabolic profile as well as with clinical observation. Early initiation of therapy is advised and should be followed by therapy adjustment once the diagnostic profile is completed. The therapy should be based on a low-protein diet and nitrogen scavengers. The long-term follow-up is based on growth and nutritional assessment, clinical and neurocognitive evaluation, and laboratory and instrumental parameter monitoring.

Availability of psychological resources for parents receiving communication of positivity at newborn screening for metabolic diseases in Italy.

Receiving information in the case of a positive or false-positive expanded newborn screening (ENBS) result for metabolic diseases is a stressful event. The availability of psychological support to families is crucial across the different communication steps and is recommended by different guidelines and position papers. However, more information is needed about the availability of psychological resources in the ENBS process. This national survey aimed to provide an overview of the availability of psychological resources for parents who received communication of positivity at the ENBS in the 23 Italian centers and how the support is provided to parents. An online survey was sent to the Heads of the ENBS centers asking about the availability of a clinical psychologist, their involvement in the ENBS process, and an estimation of parents receiving psychological support. More than 60% of the centers report having a clinical psychologist in the ENBS team; however, in more than 50% of cases, the psychologist does not participate in the consultation with parents (nor for the first consultation post-positivity or at confirmation of diagnosis). Furthermore, nearly 60% of the centers reported the experience of parental rejection of psychological sessions. Conclusion: There is a need for harmonization among the Italian ENBS centers concerning the availability of psychological resources and how these resources are provided to families. Parents' needs remained only partially fulfilled. What is Known: • Receiving communication of positivity at the ENBS can be highly stressful for parents and requires adequate psychological support. • The guidelines recommend psychological support for parents during the ENBS process. What is New: • Only 14/23 (60.9%) of Italian ENBS centers have a clinical psychologist within the team. • In half of the consultations with parents receiving communication of positivity, the clinical psychologist is never involved.

Nationwide Evaluation of Quality of Care Indicators for Individuals with Severe Mental Illness and Diabetes Mellitus, Following Israel's Mental Health Reform.

Diabetes Mellitus (DM) is more common among individuals with severe mental illness (SMI). We aimed to assess quality-of-care-indicators in individuals with SMI following the 2015 Israel's Mental-Health-reform.We analyzed yearly changes in 2015-2019 of quality-of-care-measures and intermediate-DM-outcomes, with adjustment for gender, age-group, and socioeconomic status (SES) and compared individuals with SMI to the general adult population.Adults with SMI had higher prevalences of DM (odds ratio (OR) = 1.64; 95% confidence intervals (CI): 1.61-1.67) and obesity (OR = 2.11; 95% CI: 2.08-2.13), compared to the general population. DM prevalence, DM control, and obesity rates increased over the years in this population. In 2019, HbA1c testing was marginally lower (OR = 0.88; 95% CI: 0.83-0.94) and uncontrolled DM (HbA1c > 9%) slightly more common among patients with SMI(OR = 1.22; 95% CI: 1.14-1.30), control worsened by decreasing SES. After adjustment, uncontrolled DM (adj. OR = 1.02; 95% CI: 0.96-1.09) was not associated with SMI.Cardio-metabolic morbidity among patients with SMI may be related to high prevalences of obesity and DM rather than poor DM control. Effective screening for metabolic diseases in this population and social reforms are required.

Characterisation of parathyroid hormone concentration in extremely preterm or very low birthweight infants in routine clinical screening for metabolic bone disease: A service evaluation cohort study.

To characterise parathyroid hormone (PTH) concentrations in infants at high risk for metabolic bone disease, in order to assist clinical decisions around the use of PTH for screening. Infants born under 28 weeks' postmenstrual age or with birthweight under 1.5 kg in a tertiary neonatal unit in the UK were included. Clinical guidance was to assess PTH concentration in the first 3 weeks after birth. Clinical information was extracted from prospective records. Sixty-four infants had mean birth gestation of 26 weeks and birthweight of 882 g. Median PTH (sent on median day 18 of life) was 9.2 pmol/L (interquartile range 5.3-17 pmol/L). Sixty-seven per cent of infants had a PTH greater than 7 pmol/L. For 22% of the infants, raised PTH was not accompanied by abnormal phosphate or alkaline phosphatase. Eighty-nine per cent of infants tested were insufficient or deficient for 25-hydroxyvitamin D. Universal screening highlights the high frequency of high PTH in this high-risk population, implying a need for calcium supplementation. A considerable number of infants would not be identified as showing potential signs of metabolic bone disease if the assessment excludes the use of PTH. The high level of 25-hydroxyvitamin D deficiency may be a confounder.

A Cross-sectional Real-life Study of the Prevalence, Severity, and Determinants of Metabolic Dysfunction-associated Fatty Liver Disease in Type 2 Diabetes Patients.

Most data on liver assessment in type 2 diabetes mellitus (T2DM) patients are from retrospective cohorts with selection bias. We aimed at appraising the feasibility, results, and benefits of an outpatient systematic noninvasive screening for metabolic dysfunction-associated fatty liver disease (MAFLD) severity and determinants in T2DM patients. We conducted a 50-week cross-sectional study enrolling adult T2DM outpatients from a diabetes clinic. An algorithm based on guidelines was applied using simple bioclinical scores and, if applicable, ultrasound and/or elastometry. Two hundred and thirteen patients were included. Mean age and body mass index were 62 years and 31 kg/m2 and 29% of patients had abnormal transaminase levels. The acceptance rate of additional liver examinations was 92%. The prevalence of MAFLD, advanced fibrosis and cirrhosis was 87%, 11%, and 4%, respectively. More than half of the cases of advanced fibrosis had not been suspected and were detected by this screening. MAFLD was associated with poor glycemic control, elevated transaminases, low HDL-C and the absence of peripheral arterial disease. Advanced fibrosis was linked to high waist circumference and excessive alcohol consumption, which should be interpreted with caution owing to the small number of patients reporting excessive consumption. Simple bioclinical tools allowed routine triage of T2DM patients for MAFLD severity, with high adherence of high-risk patients to subsequent noninvasive exams.

1274-P: High Prevalence of Type 2 Diabetes without Traditional Risk Factors among Men Who Inject Drugs in Chennai, India

South Asians with type 2 diabetes (T2DM) are predominately normal- or underweight, due to early loss of beta cell function in addition to insulin resistance. Substances of misuse are an additional stressor on beta cells and may lead to an increased prevalence of T2DM. We determined the prevalence of T2DM and its correlates among people who inject drugs (PWID) in Chennai. We conducted a cross-sectional analysis among male PWID. T2DM was defined as fasting glucose ≥126mg/dL or a prior diagnosis. Logistic regression was used to identify correlates of T2DM. Among 1039 PWID, median age was 38.9 years (IQR 32.1, 44.9) and median BMI was 19.7 kg/m2 (IQR 17.8, 22.9). The most common injected substance was heroin (94.8%, n=998). T2DM prevalence was 8.4% (n=87), among whom 60% were underweight or normal weight and 64% had normal waist circumference. On univariable regression analysis, T2DM was not associated with greater frequency of drug use, type of drug, HIV, or Hepatitis C. On multivariable analysis, age >40 years (OR 3.0, 95% CI 1.3-6.8) and high waist circumference (OR 1.9, 95% CI 1.1-3.2) were associated with T2DM. The prevalence of T2DM among PWID is similar to India as a whole, though most cases would not be detected by screening using weight or waist circumference. Integrating universal metabolic disease screening into substance abuse treatment programs may help reduce morbidity and mortality from T2DM. Disclosure P.Chebrolu: None.
