Micronutrient status in patients with diabetic foot ulcers: A cross-sectional study in Saudi Arabia.

Background: Patients with diabetes are at risk for developing diabetic foot ulcers (DFUs). It is recognized that type 2 diabetes (T2D) is distinguished by the loss of vitally important micronutrients because of the metabolic nature of this disease and its associated complexities. Objective: This study was performed to determine the level of micronutrients in patients with DFUs in Saudi Arabia. From February to May 2022, this descriptive study was conducted, adopting the cross-sectional design and a group of 88 patients with T2D. Materials and Methods: Applying the convenience sampling method, this study was conducted at a tertiary hospital in Riyadh, Saudi Arabia. Data collection was conducted through a standard questionnaire, and details regarding the demographic variables and micronutrient deficiency were collected. Results: Among the nutritional deficiencies identified, the one with the highest frequency was vitamin D, observed in 43.2% of the patient population; after vitamin D, in order of descent, were low ferritin levels (29.5%), B12 (13.6%), and the folic acid deficiency (12.5%). Folic acid showed a statistically significant difference among patients with cardiovascular disease (CVD) (P = 0.041). Moreover, vitamin B12 showed a significant association among patients who have charcot foot (P = 019) and previous amputation (P = 0.029). Conclusion: Vitamin B12 deficiency is significantly associated with patients who had an amputation; having charcot foot and folic acid revealed a vital relationship among patients with DFUs having CVD. Comprehensive research is a pressing need to enable deeper awareness of micronutrient deficiencies in patients with diabetes.

Factors Associated With Self-Efficacy of Foot Self-Care Among Patients With Diabetes Attending a Tertiary Care Center in Saudi Arabia.

Several reports have shown self-efficacy to be a reliable way of predicting foot self-care behavior in patients with diabetes. However, at a global level in general, and in Saudi Arabia in particular, investigation of the factors related to self-efficacy in executing foot self-care continues to remain inadequate. This study endeavors to identify the factors associated with the self-efficacy of foot self-care among patients with diabetes in Saudi Arabia. From a tertiary diabetes care center in Saudi Arabia, 175 patients with diabetes were selected to participate in this cross-sectional study. Employing the Arabic version of the Foot Care Confidence Scale (FCCS), the principal end results and the sociodemographic, clinical, and psychosocial independent variables were collected and assessed. From the total reported FCCS score, the mean was found to be 28.1 ± 8.2. Multiple linear regression analysis indicated 2 independent factors were positively associated with a higher reported FCCS score; being middle-aged (< 60 years old) (ß=0.31, P< .01) and having a higher score on the Foot Care Outcome Expectations Scale (FCOES) (ß=0.36, P< .01). In conclusion, patients with diabetes in Saudi Arabia have a mild level of self-efficacy to perform the needed foot self-care. Therefore, this has turned the spotlight on the young or middle-aged < 60-year-old Saudi population with diabetes as the target group, making them the priority for future self-efficacy promotion programs to upgrade the level of foot self-care.

Comparison of Point-of-Care and Laboratory Glycated Hemoglobin A1c and Its Relationship to Time-in-Range and Glucose Variability: A Real-World Study.

Introduction The main objective of the current study was to perform a comparison of point-of-care testing for hemoglobin A1c (POCT-HbA1c) versus the standard laboratory method (Lab HbA1c) and their relationship to time-in-range (TIR) and glucose variability (GV) among patients with diabetes mellitus (DM) presented to the outpatient diabetes clinics. Methods This single-center cross-sectional study was carried out on diabetic patients (aged ≥14 years of both genders) who undergo routine follow-up at our institution and whose physicians ordered HbA1c analysis for routine care. The included patients were those using the intermittently scanned continuous glucose monitoring (isCGM) Abbott's FreeStyle Libre system for at least three months and regular CGM users with at least 70% use. Results We included 97 diabetic patients (41 female and 56 male), with a median age of 25 years (Interquartile range= 18) and a mean DM duration of 10.33±5.48 years. The mean values of Lab-HbA1c and POCT HbA1c were 8.82%±0.85% and 8.53%±0.89%, respectively. The TIR, time below range, and time above range were 33.47±14.38 minutes (47.78%±14.32%), 5.44±2.58 minutes (8.41%±4.42%), and 28.8±8.27 minutes (43.81%±13.22%), respectively. According to the Bland-Altman plot analysis, the POCT-HbA1c values are consistent with the standard Lab-HbA1c values (SD of bias= 0.55, and 95% CI= -0.78 to 1.4). The univariate linear regression analysis showed a statistically significant relationship between laboratory HbA1c and POCT HbA1c (R2= 0.637, p <0.001), TIR (R2= 0.406, p <0.001), and GV (R2= 0.048, p= 0.032). After adjusting for age, gender, disease duration, diabetes type, and percentage of sensor data in a multivariable linear regression model, the linear associations remained significant (all p < 0.05). Conclusion The current findings show that TIR and GV can be used as endpoints and valuable parameters for the therapy of DM.

Prevalence and Risk Factors for Diabetic Peripheral Neuropathy among Patients with Type 2 Diabetes in Saudi Arabia: A Cross-sectional Study.

BACKGROUND AND AIMS: Neuropathy is the most prevalent among diabetes-related microvascular complications, of which distal symmetric polyneuropathy is very extensive. This study aimed to evaluate the frequency and risk factors for Diabetic Peripheral Neuropathy (DPN) among Type 2 Diabetes (T2D) in Saudi Arabia. METHODS: This study included 238 patients with T2D, between 18 and 80 years of age. Using a structured questionnaire, data on the sociodemographic characters of the study group and laboratory tests were collected. Distal symmetrical peripheral neuropathy in patients with diabetes was identified using the Michigan Neuropathy Screening Instrument (MNSI). RESULTS: In this cohort, 66 patients (27.7%) had positive MNSI questionnaire scores (≥ 7) and 90 (37.8%) patients had positive examination scores (≥ 2.5). From the patient's perception, patients on oral plus insulin treatment exhibited a higher risk for DPN (OR 2.95; p = 0.018) than those who received only oral treatment and an ulcer in an earlier period exhibited a higher risk for DPN (OR: 3.25; p = 0.005). From the health professionals' perception, more females than males showed a high risk for DPN (OR: 3.92; p = 0004). Likewise, compared to the patients in the age group of <50 years, those in the age group of ≥50 years revealed a high risk for DPN (OR 6.30; p = 0.009). Further, patients on oral and insulin treatments were at greater risk for DPN (OR: 3.71; p = 0.024); patients experiencing complications like prior ulcers, and high-density lipoprotein also exhibited higher risk than the patients who lacked them. CONCLUSION: Diabetes neuropathy is one of the most common complications of microangiopathy experienced by patients with T2D in Saudi Arabia. The risks for DPN among patients with T2D can be reduced with the implementation of focused and evidence-based interventions.

Evaluation of Patient Reported Satisfaction and Clinical Efficacy of Insulin Glargine 300 U/mL Versus 100 U/mL in Patients With Type 1 Diabetes Using Flash Glucose Monitoring System.

Background and Aims: To analyze patient-reported satisfaction and clinical effectiveness of concentrated insulin glargine 300 U/mL (Gla-300) among patients with type 1 diabetes (T1D) using a flash glucose monitoring (FGM) system. Methods: This comparative study was conducted among 86 patients with T1D (aged 14-40 years), who were treated with Glargine 100 U/mL (Gla-100) and switched to Gla-300 at day 1 (baseline). The following data were collected from each patient: demographic information, clinical parameters, and glycemic control markers. All patients completed the Diabetes Treatment Satisfaction Questionnaire (Arabic version), first at baseline and then after 12 weeks. A comparison was done for all the data recorded at baseline (on Gla-100) and after 12 weeks (on Gla-300) and subjected to analysis. Results: Compared to patients treated with Gla-100, significant improvements were observed in the Gla-300 group, in terms of the ambulatory glucose profile (AGP) markers, such as percentage of time spent within the target range of the glucose levels (70-180 mg/dL) (P = .037), percentage which fell below the target (<70 mg/dL) (P = .027), and percentage of time spent (<54 mg/dL) (P = .043). Compared to Gla-100, patients treated with Gla-300 experienced significant improvements in the current treatment satisfactions (P = .047), convenient finding treatment recently (P = .034), and flexible finding treatment recently (P = .041), recommend the current treatment (P = .042) and satisfied to continue the current treatment (P = .035). Conclusion: Compared to the patients on Gla-100, patients treated with Gla-300 exhibited significant improvements in the AGP markers and degree of treatment satisfaction.

Level of Agreement and Correlation Between the Estimated Hemoglobin A1c Results Derived by Continuous or Conventional Glucose Monitoring Systems Compared with the Point-of-Care or Laboratory-Based Measurements: An Observational Study.

INTRODUCTION: Hemoglobin A1C (HbA1c) is an important marker for diabetes care management. With the increasing use of new technologies such as continuous glucose monitoring (CGM) and point-of-care testing (POCT), patients and their physicians have been able to monitor and continuously check their blood glucose levels in an efficient and timely manner. This study aimed to investigate the level of agreement between the standard laboratory test for HbA1c (Lab-HbA1c) with point-of-care testing (POCT-HbA1c) and glucose monitoring index (GMI) derived by intermittently scanned CGM (isCGM) or estimated average glucose (eAG) derived by conventional self-monitored blood glucose (SMBG) devices. METHODS: A cross-sectional study was conducted at the Diabetes Treatment Center, Prince Sultan Military Medical City, Saudi Arabia, between May and December 2020 with 81 patients with diabetes who used the isCGM system (n = 30) or conventional finger-pricking SMBG system (n = 51). At the same visit, venous and capillary blood samples were taken for routine HbA1c analysis by the standard laboratory and POCT methods, respectively. Also, for isCGM users, the GMI data for 28 days (GMI-28) and 90 days (GMI-90) were obtained, while for SMBG users, eAG data for 30 days (eAG-30) and 90 days (eAG-90) were calculated. The limits of agreement in different HbA1c measurements were evaluated using a Bland-Altman analysis. Pearson correlation and multivariate linear regression analyses were also performed. RESULTS: Based on the Bland-Altman analysis, HbA1c levels for 96.7% and 96.1% of the patients analyzed by the POCT and the standard laboratory methods were within the range of the 95% limit of agreement in both isCGM and conventional SMBG users, respectively. About 93.3% of the GMI measurements were within the 95% limit of agreement. Also, about 94.12% of the eAG-30 and 90.2% of the eAG-90 measurements were within the 95% limit of agreement. Moreover, the correlation analysis revealed a statistically significant positive correlation and linear regression among Lab-HbA1c, POCT-HbA1c, GMI, and eAG in both conventional SMBG and isCGM users (all p < 0.001). These positive results persisted significantly after adjusting for different factors (all p < 0.001). CONCLUSION: GMI derived by isCGM or eAG derived by conventional SMBG systems, as well as the POCT-HbA1c measurements, showed a high level of agreement; therefore, we recommend them as potential methods for diabetes monitoring, especially when a rapid result is needed or with patients with uncontrolled diabetes or on intensive insulin therapy.

Assessment of Patient Satisfaction with On-Site Point-of-Care Hemoglobin A1c Testing: An Observational Study.

INTRODUCTION: Poor glycemic control is a serious challenge in successful diabetes management. Given the low adherence and compliance with HbA1c testing frequency and the corresponding delay in the appropriate medication adjustment, point-of-care testing (POCT) for HbA1c provides an opportunity for better control of diabetes and higher patient satisfaction. The data with this regard are limited in Saudi Arabia. Therefore, we aimed to assess the level of patient satisfaction associated with the POCT service implementation for HbA1c and evaluate the differences between the number of requested and conducted HbA1c tests before and after POCT implementation and its effect on glycemic control in Saudi clinical practice. METHODS: We conducted a single-center ambispective descriptive cohort study in Riyadh, Saudi Arabia. This study had two phases: the retrospective phase (January 2017 to December 2017) and the prospective phase (January 2018 to December 2018). Patient satisfaction was assessed using the patient satisfaction questionnaire short form (PSQ-18) and on-site HbA1c point-of-care testing (HbA1c-POCT) satisfaction questionnaire. RESULTS: This study included 75 patients with diabetes (37% type 1, 63% type 2) with a mean age of 44.35 (± 17.97) years. The adherence to physician recommendations for HbA1c testing frequency increased from 24% to 85% (before and after POCT implementation, respectively). High levels of satisfaction across seven dimensions of PSQ-18 (77-88%) were reported towards the provided healthcare service after POCT implementation. Furthermore, a high level of agreement on the statements of the on-site HbA1c-POCT satisfaction questionnaire was also observed. Finally, the mean HbA1c level has significantly improved after POCT implementation compared to the traditional HbA1c laboratory testing before POCT implementation [8.34 ± 0.67 and 8.06 ± 0.62, respectively, p < 0.001). CONCLUSION: HbA1c testing at POCT improved adherence to recommendations for HbA1c testing frequency for better glycemic control and higher patient satisfaction. POCT reduces turnaround time, improves glycemic control, and facilitates the decision-making process. HbA1c measurement with POC devices is recommended to be implemented in diabetes treatment centers. All of the described benefits of POCT come together to make HbA1c testing the most common procedure for diabetes management at the point of care.

COVID-19 among people with diabetes mellitus in Saudi Arabia: Current situation and new perspectives.

BACKGROUND AND AIM: This review aims to report the current status of COVID-19 among people with diabetes, newly diagnosed diabetes, diabetic ketoacidosis, and programmatic efforts including vaccinations. METHODS: We conducted a literature search using PubMed, Google, and Scopus until July 15, 2021. RESULTS: In Saudi Arabia, most studies have reported diabetes as one of the highly prevalent comorbidities among patients with COVID-19. Currently, there are limited studies from Saudi Arabia on the newly diagnosed diabetes and diabetic ketoacidosis caused by COVID-19. The Saudi ministry has taken several measures to control the impact of COVID-19 among people with diabetes, including comprehensive guidelines and prioritized vaccinations. During the COVID-19 pandemic, the use of telehealth services dramatically increased in diabetes clinics in Saudi Arabia. CONCLUSIONS: Focused and evidence-based interventions are essential to control the impact of COVID-19 among people with diabetes.

Evaluation of Risk Factors Associated with Diabetic Foot Ulcers in Saudi Arabia.

BACKGROUND AND AIMS: Considering that diabetic foot ulceration is one of the major health issues globally, we aimed to evaluate the risk factors associated with foot ulcers in patients with type 2 diabetes mellitus (T2DM). METHODS: A total of 81 T2DM patients (age range: 40-80 years) registered at the Diabetes Treatment Center, Prince Sultan Military Medical City (PSMMC), Riyadh, Saudi Arabia between April and September 2015 were included in this cross-sectional study after purposive selection and assigning of patient numbers. The selected participants were interviewed and examined, and their medical records were reviewed for sensory, vibratory, and painful neuropathies; vascular insufficiency; retinopathy; and dermatological variations. The Wagner's classification system was employed to evaluate the stage of patients' foot ulcers. RESULTS: Among the study participants [mean age range: 56.4 ± 6.72 years; 53 males (65.4%)], cases of loss of protective sensation, foot deformity, amputation history, and dermatological abnormalities were notable. The Wagner gradation value of ulcers were grade 0 for 16% study population, grade 1 for 35.8%, grade 2 for 45.7%, grade 3 for 2.5%, and grades 4 and 5 for 0%. Approximately 19% of the patients had a previous case of amputation and 29.6% had nail disease. The most common footwear reported to be used by the patients was sandals shoes (46%). CONCLUSION: The issues of loss of protective sensation, vascular insufficiency, deformity, previous amputations, and dermatological abnormalities of the lower limbs were found to be most common among the foot ulceration patients. The study findings thus recommend regular foot examination, following basic hygiene habits, encouragement of the use of appropriate footwear, patient education about foot ulcers, and prompt treatment for minor injuries to prevent further ulceration in DM patients.

An Inverse Relationship Between Age of Type 2 Diabetes Onset and Complication Risk and Mortality: The Impact of Youth-Onset Type 2 Diabetes.

OBJECTIVE: This study compared the prevalence of complications in 354 patients with T2DM diagnosed between 15 and 30 years of age (T2DM15-30) with that in a duration-matched cohort of 1,062 patients diagnosed between 40 and 50 years (T2DM40-50). It also examined standardized mortality ratios (SMRs) according to diabetes age of onset in 15,238 patients covering a wider age-of-onset range. RESEARCH DESIGN AND METHODS: Complication status was assessed according to a standard protocol and extracted from our electronic database. Survival status was ascertained by data linkage with the Australian National Death Index. SMRs were calculated in comparison with the background Australian population and analyzed according to age of onset. RESULTS: After matching for duration, despite their younger age, T2DM15-30 had more severe albuminuria (P = 0.004) and neuropathy scores (P = 0.003). T2DM15-30 were as commonly affected by metabolic syndrome factors as T2DM40-50 but less frequently treated for hypertension and dyslipidemia (P < 0.0001). An inverse relationship between age of diabetes onset and SMR was seen, which was the highest for T2DM15-30 (3.4 [95% CI 2.7-4.2]). SMR plots adjusting for duration show that for those with T2DM15-30, SMR is the highest at any chronological age, with a peak SMR of more than 6 in early midlife. In contrast, mortality for older-onset groups approximates that of the background population. CONCLUSIONS: The negative effect of diabetes on morbidity and mortality is greatest for those diagnosed at a young age compared with T2DM of usual onset. These results highlight the growing imperative to direct attention toward young-onset T2DM and for effective interventions to be applied before middle age.

Diabetes Mellitus in Saudi Arabia: A Review of the Recent Literature.

The World Health Organization (WHO) has reported that Saudi Arabia ranks the second highest in the Middle East, and is seventh in the world for the rate of diabetes. It is estimated that around 7 million of the population are diabetic and almost around 3 million have pre-diabetes. Even more worrying perhaps, is the increasing pattern of diabetes noted in Saudi Arabia in the recent past. In fact, diabetes has approximately registered a ten-fold increase in the past three eras in Saudi Arabia. Diabetes mellitus (DM) has been found to be related to high mortality, morbidity and vascular complications, accompanied by poor general health and lower quality of life. In Saudi Arabia, DM is quickly reaching disturbing proportions and becoming a significant cause of medical complications and even death. However, when compared with the developed countries, the research work conducted, focusing particularly on the incidence, prevalence and socio-demographic properties of DM is woefully inadequate. The health burden due to DM in Saudi Arabia is predicted to rise to catastrophic levels, unless a wide-ranging epidemic control program is incorporated, with great emphasis laid on advocating a healthy diet, including exercise and active lifestyles, and weight control. To properly manage the DM in Saudi Arabia, a multidisciplinary approach is required. In this review we discuss all the aspects of DM in Saudi Arabia drawing from the published literature currently available.

Assessment of health-related quality of life among adolescents with type 1 diabetes mellitus in Saudi Arabia.

OBJECTIVE: To evaluate the health-related quality of life (HRQoL) for adolescents with type 1 diabetes mellitus (T1DM). METHODS: A cross-sectional study was conducted among 214 adolescents (13-18 years) with T1DM at the Diabetes Treatment Center, Prince Sultan Military Medical City, Riyadh, Saudi Arabia from June to September 2013. Respondents were selected by their availability during routine visits to outpatient clinics, and interviewed using the Arabic translated version of the Pediatric Quality of Life Inventory 3.0 Diabetes Module (PedsQL 3.0 DM) independently. RESULTS: Female gender, multiple daily injection (MDI), longer duration of T1DM (>7 years), diabetic ketoacidosis (DKA) and adolescents with >7 HbA1c level had at least one poor HRQoL outcome. Multivariate linear regression analysis showed that age, treatment type (MDI), DKA, and >7 HbA1c were independent influencing factors for subscale diabetes symptoms, whereas >7 HbA1c was the independent influencing factor for treatment barriers and overall HRQoL. The DKA was the independent influencing factor for the subscale of worry, and female gender was the independent influencing factor for the subscale of communication. CONCLUSION: Female gender, age, treatment type, >7 HbA1c, and DKA are the strongest determinants for lower HRQoL for at least one subscale of the PedsQL 3.0 DM.

Factors Associated with Health-Related Quality of Life among Saudi Patients with Type 2 Diabetes Mellitus: A Cross-Sectional Survey.

BACKGROUND: Diabetes mellitus (DM) is associated with high mortality, morbidity, poor general health, and loss of health-related quality of life (HRQOL). The objective of the study was to assess the factors associated with HRQOL among patients with type 2 diabetes mellitus (T2DM). METHODS: This was a cross sectional study conducted among 283 T2DM patients during June 2011 and September 2012 at a major tertiary hospital in Riyadh, Saudi Arabia. The respondents were purposively and conveniently selected according to their availability during their routine visit to the outpatient clinics and they were interviewed using the Arabic version of the Short-Form 36-item survey (SF-36) to assess the HRQOL. RESULTS: The mean age of the participants was 56.4±13.2 years. Around 63% (178) were males and 37% (105) were females. Glycosylated hemoglobin level was found to be significantly higher among female and HRQOL was higher among male. Respondents who were more than 50 years old had poor HRQOL than less than 50 years age group. Poor economic status, reported diabetic complications and longer duration of diabetes were significantly associated with poor HRQOL. The respondents treated with combination of therapies (oral medication plus insulin) indicated better HRQOL than patients with insulin therapy alone. Multivariate analysis indicated that gender, economic status (except subscale energy), and complications of DM (except subscale energy) as independent risk factor for HRQOL. CONCLUSION: Gender, economic status, and complication of DM were independent risk factors for majority of the subscales of HRQOL.

Long-term complications and mortality in young-onset diabetes: type 2 diabetes is more hazardous and lethal than type 1 diabetes.

OBJECTIVE: To evaluate long-term clinical outcomes and survival in young-onset type 2 diabetes (T2DM) compared with type 1 diabetes (T1DM) with a similar age of onset. RESEARCH DESIGN AND METHODS: Records from the Royal Prince Alfred Hospital Diabetes Clinical Database, established in 1986, were matched with the Australian National Death Index to establish mortality outcomes for all subjects until June 2011. Clinical and mortality outcomes in 354 patients with T2DM, age of onset between 15 and 30 years (T2DM15-30), were compared with T1DM in several ways but primarily with 470 patients with T1DM with a similar age of onset (T1DM15-30) to minimize the confounding effect of age on outcome. RESULTS: For a median observation period of 21.4 (interquartile range 14-30.7) and 23.4 (15.7-32.4) years for the T2DM and T1DM cohorts, respectively, 71 of 824 patients (8.6%) died. A significant mortality excess was noted in T2DM15-30 (11 vs. 6.8%, P = 0.03), with an increased hazard for death (hazard ratio 2.0 [95% CI 1.2-3.2], P = 0.003). Death for T2DM15-30 occurred after a significantly shorter disease duration (26.9 [18.1-36.0] vs. 36.5 [24.4-45.4] years, P = 0.01) and at a relatively young age. There were more cardiovascular deaths in T2DM15-30 (50 vs. 30%, P < 0.05). Despite equivalent glycemic control and shorter disease duration, the prevalence of albuminuria and less favorable cardiovascular risk factors were greater in the T2DM15-30 cohort, even soon after diabetes onset. Neuropathy scores and macrovascular complications were also increased in T2DM15-30 (P < 0.0001). CONCLUSIONS: Young-onset T2DM is the more lethal phenotype of diabetes and is associated with a greater mortality, more diabetes complications, and unfavorable cardiovascular disease risk factors when compared with T1DM.
