Hemostatic state augmented with platelet indices among Sudanese diabetic septic foot

Assessment of Glycemic Control in Patients With Diabetes in Northern Sudan Using Calculated HbA1c

BACKGROUND

Diabetes mellitus (DM) significantly burdens health services worldwide. As a simple and cost-effective method, the mathematical calculation of HbA1c is coming to be of value in areas with scarce resources. This study aimed to use calculated HbA1c to ascertain the prevalence of uncontrolled DM and correlate it with the risk factors for DM.

METHODS

In the River Nile State of northern Sudan, a cross-sectional study was conducted in five leading cities from May to August 2021. Patients diagnosed and recorded as having type 2 or type 1 DM were included in this study. Enzymatic methods were used to assess fasting blood glucose (FBG). We used the mean of three FBG readings for three months to calculate HbA1c using the equation {HbA1c = (FBG mg/dl) x 0.03+2.6}, which was used to compute the estimated mediocre blood sugar over the course of three months.

RESULTS

A total of 2047 diabetic patients from northern Sudan were studied for their DM control. Nearly two-thirds (65.2%) had uncontrolled DM. Of the patients studied, uncontrolled DM was significantly positively associated with older age, history of ischemic heart disease, and being a housewife. Multivariate regression analysis showed significant correlations between uncontrolled DM, an inactive lifestyle, and obesity.

CONCLUSION

The prevalence of uncontrolled DM among known patients with diabetic in northern Sudan is high (65.2%). The inactive lifestyles of housewives and freelance workers, having type 1 DM, and being hypertensive and obese are risk factors significantly associated with uncontrolled DM and its related complications.

Prevalence of diabetic foot amongst adults with diabetes mellitus in northern Sudan: A cross-sectional study

OBJECTIVE

The aim of this study was to determine the prevalence and associated factors for diabetic foot (DF) amongst patients with diabetes Mellites (DM) in Nahr an Nil State (River Nile State), Sudan.

METHODS

We conducted a cross-sectional study between May and August 2018. DM patients were examined for DF, and clinical data were collected through a questionnaire.

RESULTS

A total of 2048 DM patients were enrolled in the study. Their median (interquartile range) age was 58 (15) years. Over half (54.2%) of the patients were female. The median (interquartile range) of the duration of diabetes was 5 (6) years. In this sample, 70.1% of the patients had type 2 DM and 47.6% had hypertension as well. Of all enrolled patients, 21.2% had normal weight, 1.2% were underweight, 37.2% were overweight and 40.4% were obese. Two hundred and sixty (12.7%) patients had DF. Multivariate regression analyses showed that age [adjusted odds ratio (AOR) = 1.21; 95% confidence interval (CI): 1.18-1.24] and duration of DM (AOR = 1.09; 95% CI: 1.05-1.14) were positively associated with DF. Moreover, type 2 DM (AOR = 1.77; 95% CI: 1.17-2.68), family history of DM (AOR = 1.5; 95% CI: 1.07-2.09), hypertension (AOR = 2.93; 95% CI: 2.07-4.16) and obesity (AOR = 2.86; 95% CI: 1.70-4.81) were associated with DF. There was no significant association between DF and gender or overweight status.

CONCLUSION

This study found a high prevalence of DF. Older age, type 2 DM, duration of DM, family history of DM and hypertension are associated with DF.

Risk Factors for Major Amputation in Diabetic Foot Ulcer Patients

BACKGROUND

The purpose of our study was to identify the new and the more specific risk factors for major amputation in patients with diabetic foot ulcer (DFU).

METHODS

We used data from the Electronic Medical Record (EMR) database of our hospital from February 2014 to July 2020. Patients with DFU and amputation were included in the study. The logistic regression model was adjusted for demographic characteristics and related comorbidities between major and minor amputation groups.

RESULTS

Among 3654 patients with DFU, 363 (9.9%) were amputated. Patients with major versus minor amputation, in multivariable logistic regression models, major amputation independent factors included previous amputation history (odds ratio [OR] 2.31 [95% CI 1.17-4.53], p = 0.02), smoking (2.58 [1.31-5.07], p = 0.01), coronary artery disease (CAD) (2.67 [1.35-5.29], p = 0.03), ankle brachial index (ABI) <0.4 (15.77 [7.51-33.13], p < 0.01), Wagner 5 (5.50 [1.89-16.01], p < 0.01), activated partial thromboplastin time (APTT) (1.23 [1.03-1.48], p = 0.01), glycosylated hemoglobin A1c (HbA1c) (1.23 [1.03-1.48], p = 0.03), hemoglobin (Hb) (0.98 [0.96-1.00], p = 0.01), plasma albumin (ALB) (0.88 [0.81-0.95], p < 0.01) and white blood cell (WBC) (1.10 [1.04-1.16], p < 0.01).

CONCLUSION

Major amputation was associated with previous amputation history, smoking, CAD, Wagner 5, ABI <0.4, HbA1c, Hb, ALB, WBC, and APTT might be a new independent factor. In view of these factors, early prevention and guidance promptly orientated by multidisciplinary is of great significance to reduce the disability rate and economic burden.

Utility of Tetrahydrobiopterin Pathway in the Assessment of Diabetic Foot Ulcer: Significant and Complex Interrelations

OBJECTIVES

Tetrahydrobiopterin (BH4) pathway that included generation of neopterin (Neop), biopterin (Biop), and nitric oxide (NO) is altered in type 2 diabetes (T2D). The aim of this study was to assess the biomarkers of BH4 pathway in noninfected DFUs and to relate these levels to the variables of diabetes as well as to the hematological indices.

METHODS

We performed a cross-sectional investigating study in a Kurdish people including 30 healthy subjects (group I), 66 T2D patients (group II), and 57 DFUs patients (group III). Hematological indices including red cell distribution width (RDW), mean platelet volume (MPV), and platelet distribution width (PDW) were determined by Coulter hematological analysis. Serum BH4 markers including NO, Neop, and Biop were determined by using an enzyme-linked immunosorbent assay (ELISA) technology. The relationship between BH4 markers with glycemic and hematological indices was assessed by Spearman's correlation and multivariable regression analysis.

RESULTS

Neop was significantly increased while PDW was significantly decreased in group III compared with group II patients. Nitric oxide was found to be inversely correlated with age (r = -0.382), duration of diabetes (r = -0.264), mean arterial blood pressure (r = -0.532), body mass index (r = -0.321), RDW (r = -0.322), and PDW (r = -0.284) in group III patients. Circulating Neop and Biop significantly correlated with RDW and erythrocyte sedimentation rate. Multivariable regression analysis revealed that serum Neop predicted the DFUs in 92.5% of group III patients.

CONCLUSION

Tetrahydrobiopterin biomarkers are predictors of DFUs and the significant correlation of neopterin with red distribution width and erythrocyte sedimentation rate indicating the role of neopterin in the vascular and inflammation concerns of noninfected DFUs.
