Risk factors for expression and progression of limited joint mobility in insulin-dependent childhood diabetes

Association of limited joint mobility and increased plantar hardness in diabetic foot ulceration in north Asian Indian: a preliminary study

The aim of this article is to investigate the association of limited joint mobility and foot sole hardness in north Asian Indian type 2 diabetic patients. Limited joint mobility and hardness of the foot sole were measured for 39 subjects attending the AIIMS Endocrinology & Metabolism Clinic. The total subject divided into three groups: 13 control subjects (nondiabetic), 13 diabetic patients without neuropathy and 13 diabetic neuropathy patients. Neuropathy status was assessed using 10 gm Semen's Weinstein monofilament. Joint mobility parameters, such as ankle dorsiflexion/plantar flexion and metatarsophalangeal-1 dorsiflexion/plantar flexion, are measured using a goniometer. Foot sole hardness was measured using a durometer or shore meter. We found that diabetic patients with a neuropathic foot had significantly reduced joint mobility and increased foot sole hardness, placing them at risk for subsequent ulceration. Metatarsophalangeal-1 dorsiflexion/plantar flexion of both feet of diabetic patients had significant correlation (at p < 0.05, p < 0.001, p < 0.001 level) over age and body mass index. Also ankle plantar flexion/dorsiflexion and metatarsophalangeal-1 dorsiflexion/plantar flexion has a significant correlations (at p < 0.01, p < 0.05, p < 0.001, p < 0.001 level) with foot sole hardness in both feet of diabetic neuropathy subjects. Also linear regression analysis showed that duration of diabetes was significantly associated with the joint mobility parameters. In this study we conclude that joint mobility had reduced further if neuropathy and increased foot sole hardness coexisted owing to high plantar pressures. Hence, both limited joint mobility and increased foot sole hardness appears to be important determinants of foot sole ulceration in diabetic neuropathic subject.

Rheumatic manifestations of diabetes mellitus

DM is associated with various musculoskeletal manifestations. The strength of this relationship varies among the various musculoskeletal disorders; the associations are based mostly on epidemiologic data. For most of these conditions, definitive pathophysiologic correlates are lacking.Hand and shoulder disorders occur more frequently than other musculoskeletal manifestations of DM. Recognition of the association between DM and shoulder adhesive capsulitis, DD, and stenosing flexor tenosynovitis facilitates their correct diagnosis in the setting of DM and prompt initiation of appropriate treatment, which may include optimizing glycemic control. Conversely, awareness and identification of the characteristic musculoskeletal manifestations of DM may facilitate earlier diagnosis of DM and initiation of glucose-lowering therapy to retard the development of diabetic complications.Much less has been published about the musculoskeletal complications of DM than about its micro- and macrovascular complications. Prospective case-control cohort studies are needed to establish the true prevalence of musculoskeletal complications of DM and the metabolic syndrome, especially in this era of tighter glycemic control.The potential relationship between DM and the development of OA needs to be clarified in large, prospective, case-control cohort studies. The effect on musculoskeletal manifestations of various therapeutic regimens to manage DM should be studied prospectively. Treatment regimens for some musculoskeletal conditions associated with DM, such as DISH, should be studied in larger prospective, randomized,controlled clinical trials.At the molecular level, further studies are warranted to clarify the potential contribution of AGEs and adipokines to the development of OA and diabetic musculoskeletal syndromes, such as shoulder adhesive capsulitis, DD, stenosing flexor tenosynovitis, and LJM. Identification of such molecular targets for therapy would promote the development of additional treatments for these and other rheumatic diseases.

The diabetic hand: a forgotten complication?

The manifestations of diabetes in the hand were much discussed in the 1970s and 1980s. The present review aims to revisit the diabetic hand and to discuss the pathology of the hand that may be clinically important in diabetic patients. In the strict sense of the term, the "diabetic hand" encompasses the three most widely studied conditions which have traditionally been associated with diabetes, namely limited joint mobility, Dupuytren's contracture and trigger finger. There is evidence that these entities are significantly more frequent in patients with diabetes and also that they may be associated with diabetes duration, poor metabolic control and presence of microvascular complications. In a more general sense, though, there are other conditions affecting the hands, which also occur more frequently in diabetes. From a practical point of view, increased alertness both for neuropathic hand ulcers in patients with profound neuropathy and for diabetic hand infections is absolutely necessary. Recently, reduced hand strength is beginning to be recognized as a further complication of diabetes. Thus, the hand may reveal substantial pathology in diabetes, and ideally, clinical examination should not ignore it.

Longitudinal relation between limited joint mobility, height, insulin-like growth factor 1 levels, and risk of developing microalbuminuria: the Oxford Regional Prospective Study

AIMS

To determine risk factors for development of microalbuminuria (MA) in relation to detection of limited joint mobility (LJM+) of the interphalangeal joints in a longitudinal cohort of type 1 diabetic (T1DM) subjects.

METHODS

A total of 479 T1DM subjects diagnosed <16 years were followed from diagnosis of diabetes with annual assessments consisting of assessment of LJM, measurement of HbA1c and insulin-like growth factor 1 (IGF-1), and three urine samples for albumin:creatinine ratio (ACR).

RESULTS

After a median follow up of 10.9 years, 162 subjects (35.1%) developed LJM at median age 13.0 years and duration 5.2 years. More subjects developed LJM after compared to before puberty (67.6 v 32.4%). In LJM+ compared to LJM- subjects, HbA1c (mean 10.1 (SD 1.6) v 9.6 (1.4) %)) and ACR levels (median 1.1 (range 0.2-242.9) v 0.9 (0.4-70.7) mg/mmol) were higher, and in a Cox model probability of developing LJM was related to puberty and higher HbA1c levels. ACR levels were higher after detection of LJM compared to before (median 1.2 (range 0.4-102.6) v 0.8 (0.2-181.9) mg/mmol). Probability of developing MA was related to puberty, HbA1c, female sex, and presence of LJM (a 1.9-fold increased risk). Both LJM and MA were associated with lower height SDS (LJM: mean 0.0 (SD 1.0) v 0.2 (1.1); MA: 0.0 (1.0) v 0.2 (SD 1.0)) and lower IGF-1 levels.

CONCLUSION

The development of LJM was associated with an increased risk of microalbuminuria, independent of glycaemic control. Risk for both microalbuminuria and LJM was associated with puberty, reduced growth, and reduced IGF-1 levels, and may indicate underlying shared pathogenic mechanisms.

Early subclinical limited axial and large joint flexibility in type 1 diabetes mellitus adolescents

OBJECTIVE

The objective of this study was to compare the axial and large joint mobility in adolescents with and without type 1 diabetes mellitus (DM1).

PATIENT AND METHODS

To check this relationship, 72 DM1 adolescents aged 9-20 years were admitted into the trial and compared with 46 healthy control subjects aged 10-18 years. The youths were compared with regard to anthropometrics (age, proportion female/male, weight, height, and BMI) data. The years from DM1 diagnosis and HbA(1c) (index) were 4.9 +/- 3.6 years and 1.40 +/- 0.39%, respectively. The values of the tests of flexibility of the movements of cervical joint, the abduction of scapular, wrist and back-lumbar joints and abduction of lame-femoral were obtained through the Fleximeter.

RESULTS

The DM1 patients and controls did not differ regarding age (DM1 median 16, range 9-20 years vs. controls 16, range 10-18 years) and BMI (DM1 mean+/-S.D. 21.49 +/- 3.69 kg/m(2) vs. controls 20.76 +/- 2.81 kg/m(2)). The scapular, back-lumbar, and lame-femoral flexibility were, respectively, significantly lower (P < .001) in DM1 adolescents (175 +/- 8 degrees , 107 +/- 4 degrees , 66 +/- 10 degrees) compared with controls (189 +/- 13, 116 +/- 14, 76 +/- 12), but the cervical joint mobility was the same in both groups (DM1: 98 +/- l2 degrees vs. control: 101 +/- 13 degrees).

CONCLUSION

Thus, the results of our study show a subclinical limited axial and large joint mobility in DM1 adolescents. Future prospective studies are needed to ascertain whether the joint limitations found in these DM1 adolescents will persist into adulthood and play a role in the development of other diabetic complications.

Limited joint mobility in type 1 diabetic patients: associations with microangiopathy and subclinical macroangiopathy are different in men and women

OBJECTIVE

To study the relationship of limited joint mobility (LJM) in type 1 diabetic patients with microvascular complications, hypertension, and early atherosclerosis and to determine whether sex has an influence on possible associations.

RESEARCH DESIGN AND METHODS

A total of 335 consecutive unselected patients (191 women and 144 men), aged 14-40 years, were studied for LJM, retinopathy, nephropathy (stages III and IV), and hypertension. Standard laboratory tests were performed; the intima-media thickness (IMT) of the carotid arteries, which reflects the extent of early atherosclerosis, was measured by high-resolution ultrasound, and plaques were identified.

RESULTS

The frequency of LJM was 33.7% (29.8% in women and 38.9% in men). Subjects with LJM had a longer diabetes duration (P < 0.001) than those without (women 16.7 +/- 9.1 vs. 10.3 +/- 6.0 years; men 15.0 +/- 9.0 vs. 9.4 +/- 6.3 years). Age, HbA1c, lipids, and systolic/diastolic blood pressure were not different between men and women with or without LJM. Men with LJM had a higher albumin excretion rate (37.1 vs. 13.1 microg/min, P < 0.05) than those without LJM and showed a higher risk of proteinuria (odds ratio 1.8, 95% CI 1.2-2.7; P < 0.05), retinopathy (2.4, 1.7-3.5; P < 0.001), and hypertension (1.7, 1.2-2.6; P < 0.05). The occurrence of these complications was not different between women with and without LJM, but only women with LJM had a greater IMT (0.59 +/- 0.13 vs. 0.55 +/- 0.10 mm, P < 0.05) and a higher risk of plaques (odds ratio 2.1, 95% CI 1.3-3.4; P < 0.05) than women without LJM. In a multiple logistic regression analysis, adjusted for age and diabetes duration, male sex independently predicted the presence of LJM. Moreover, LJM proved to be an independent predictor of retinopathy in men only.

CONCLUSIONS

LJM is an indicator of microvascular disease in men, and LJM is associated with early macrovascular disease in women.
