Early elucidation for the causation of CN with the neurotraumatic and neurovascular theories were accurate in their times. Of late, the conceptual understanding of CN has evolved after description of the role of osteoclastic resorption of foot bones by activation of receptor activator of nuclear factor kappa-B (RANK). The activation of RANK by RANK ligand (RANKL) occurs as a result of recurrent trauma to an insensate foot inciting a pro-inflammatory cascade of multiple inflammatory cytokines locally, the most common being tumour necrosis factor-α (TNF-α), interleukin-1ß (IL-1β) and interleukin-6 resulting in a local 'cytokine storm'. In addition, non-inflammatory factors including hyperglycemic milieu by increasing advanced glycosylation end products (AGEs), and autonomic neuropathy by causing a decrease in calcitonin gene-related peptide (CGRP) and endothelial nitric oxide synthase, can upregulate the RANKL\u002F NF-кB pathway.\n\nActive CN of foot is defined clinically as a localised swelling, erythema and temperature difference exceeding 2˚C compared to a similar site on the opposite foot. The knee high non-removable total contact cast (TCC) is preferred as the treatment for the management of active CN.\n\nProblem Statement: TCC has inherent limitations including worsening of bone mineral density (BMD), cast-related tissue injury, shin ulcers and prolonged immobilization usually for 6 to 12 months) and adversely impact the quality of life of individuals with CNO. Moreover, TCC is associated with sweating, maceration, in-TCC skin ulceration and intolerance in hot weather of tropical countries.\n\nA knee-high walker rendered non-removable is suggested as a second choice in order to immobilise and offload the foot as a conditional recommendation with low quality of evidence. Presently there are no randomized controlled head-to head comparison of these non-removable knee high devices for active CNO.\n\nHence, this shall be the first study to the best of our knowledge for head-to-head comparison of two different offloading strategies for active CNO.\n\nMethods:\n\nThe diagnosis of active CN shall be further corroborated by X-ray and\u002For magnetic resonance imaging (MRI) (3T scanner Siemens MagnetromVerio). Sanders-Frykberg classification will be used for anatomical grading and localization of the involved site of the foot. A written informed consent shall be obtained from all participants.\n\nClinical details regarding duration of symptoms, inciting event, diabetes duration and coexisting microvascular and macrovascular diabetic complications will be recorded. Detailed neurological examination shall be performed including vibration perception threshold (VPT\\>25 mV was considered as abnormal) by biothesiometer-Vibrometer-VPT1(Diabetik Foot Care, Madras Engineering Service, India), 10-g monofilament (Diabetik Foot Care, Madras Engineering Service, India) perception at 5 standardized plantar sites and ankle reflex. Foot temperature shall be measured by infrared dermal thermometry (FLIR Systems Inc, Orlando, USA) with a pixel resolution of 4800 (80, 60), thermal sensitivity of \\\u003C0.15˚C and range of detection from -20˚C to 250˚C.\n\nBlood sample for biochemistry, bone turnover markers (BTMs) and inflammatory cytokines shall be collected after an overnight fast (8-10 hours) and analysed by ECLIA.\n\nAll participants will be randomised by one of the investigators at each site using computer generated randomisation blocks in 1:1 to either receive standardised non-walking, non-removable, knee high, fibre-glass total contact cast (group A) or posterior non-removable knee high slab (group B) for immobilisation.\n\nAll participants will be followed fortnightly and change of cast shall be performed in view of 'pistoning' effect due to reduction of edema at each visit. An average of 3 temperature recordings at the ROI of foot will be obtained after the removal of cast for 30 minutes, during each follow up visit. Inflammatory cytokines, BTMs shall be evaluated at baseline and at clinical remission or 12 months (whichever occurred earlier). Clinical remission of active CN shall be defined as a temperature difference \\\u003C2˚C between the affected foot and a similar site (temperature obtained thrice) on the opposite foot on two successive follow-up visits two-four weeks apart.\n\nStatistical analysis:\n\nNormality of the data for each variable shall be assessed by Kolmogorov-Smirnov test. Data shall be expressed as mean ± SD if normally distributed and as median and inter-quartile range if skewed. Student T-test shall be used to compare the means of two groups for parametric data and Mann-Whitney U test for non-parametric data. Comparison of proportion of participants achieving remission shall be performed by Mc Nemar test.\n\nA Kaplan-Meier curve shall be constructed to assess the difference in remission of active CN with the interventions. Cox proportion hazard model will be used to identify the association between the baseline variables and incident remission. The variables are decided by their clinical relevance to active CN of foot.\n\nSample Size: 80 patients are required to be 80% sure that the upper limit of a one-sided 95% confidence interval (or equivalently a 90% two-sided confidence interval) will exclude a difference in favour of the TCC of more than 20%.",[38,44],{"label":39,"type":40,"description":41,"interventionNames":42},"Total Contact Cast (TCC) Comparator Arm","ACTIVE_COMPARATOR","standardised non-walking, non-removable, knee high, fibre-glass total contact cast",[43],"Device: Total Contact Cast",{"label":45,"type":40,"description":46,"interventionNames":47},"Posterior Slab Comparator Arm","posterior non-removable knee high slab",[48],"Device: Posterior Slab",[50,55],{"type":51,"name":52,"description":53,"armGroupLabels":54,"otherNames":24},"DEVICE","Total Contact Cast","Knee High Fiber Glass Total contact Cast",[39],{"type":51,"name":56,"description":57,"armGroupLabels":58,"otherNames":24},"Posterior Slab","Posterior Slab Knee high non walking",[45],[60],{"name":61,"affiliation":62,"role":63},"Ashu Rastogi, DM MD","PGIMER, India","PRINCIPAL_INVESTIGATOR",[65],{"name":61,"role":66,"phone":67,"phoneExt":24,"email":68},"CONTACT","9781001046","rastogi.ashu@pgi.ac.in",[70],{"facility":71,"status":72,"city":73,"state":24,"zip":74,"country":75,"countryCode":76,"cosmosGeoPoint":77,"geoPoint":82,"contacts":83},"Department of Endocrinology, PGIMER","RECRUITING","Chandigarh","160012","India","IN",{"type":78,"coordinates":79},"Point",[80,81],76.7884,30.73629,{"lat":81,"lon":80},[84],{"name":85,"role":66,"phone":67,"phoneExt":24,"email":86},"Ashu Rastogi, DM","rastogi.ashu@pgimer.ac.in",{"type":63,"investigatorFullName":88,"investigatorTitle":89,"investigatorAffiliation":5,"oldNameTitle":24,"oldOrganization":24},"Ashu Rastogi","Associate Professor","100560162",false,"NCT06573554","Contact Cast Versus Posterior Slab as Offloading Modality for Charcot Neuroarthropathy","Contact Cast Versus Posterior Slab as Offloading Modality for Charcot Neuroarthropathy of Foot in Diabetes (OFFLOAD Study): A Multicentric, Non-inferiority Study","Inclusion Criteria:\n\n* Type 2 Diabetes Mellitus\n* Unilateral pedal swelling\n* Active Charcot Neuroarthropathy\n* Age: 18 years and above.\n* Ability to Provide Consent\n\nExclusion Criteria:\n\n* presence of pedal ulcer,\n* osteoporosis (T score \\\u003C-2.5 at lumbar spine or hip),\n* gout,\n* active peptic ulcer disease,\n* steroid intake in the last three months,\n* estimated glomerular filtration rate (eGFR) \\\u003C30 ml\u002Fmin\u002Fm2,\n* active dental caries or invasive dental procedure,\n* peripheral vascular disease (ABI \\\u003C 0.7),\n* bilateral foot involvement,\n* pregnant\u002F lactating women and\n* those who had recently received antiresorptive agents (in the previous 12 months).\n* Negative consent","ALL","18 Years",{"count":99,"type":100},80,"ESTIMATED","INTERVENTIONAL",[103],"NA","Charcot neuroarthropathy (CN) is a condition in diabetic patients characterized by foot swelling, redness, and a temperature difference exceeding 2˚C compared to the other foot.
