Associations of major dietary patterns with cardiometabolic risk factors among Iranian patients with type 1 diabetes.

Objective: To examine the associations between dietary patterns and cardiometabolic risk factors among type 1 diabetic (T1D) patients. Methods: This cross-sectional study was conducted on 229 Iranian T1D patients. Data on dietary intakes were collected using a 168-item food frequency questionnaire. To identify major dietary patterns, we merged data on the 168 food items to obtain 23 food groups. Then, we constructed major dietary patterns using factor analysis with varimax rotation. We used binary logistic regression to assess the association between dietary patterns and cardiometabolic risk factors, in which potential confounders were adjusted. Results: Four dietary patterns were identified: Western, unhealthy, traditional, and semi-healthy patterns. After adjusting for confounders including demographic variables, physical activity, energy intake, and medical history, participants in the highest tertile of the Western dietary pattern had 2.53 (95 % CI: 1.03-6.22) and 3.37 (95 % CI: 1.18-9.63) times more odds of elevated HbA1c and low estimated glucose disposal rate (eGDR), respectively, compared with those in the lowest tertile. Such the positive association was also seen for elevated fasting blood glucose (FBG). Moreover, individuals in the top tertile of unhealthy diet had more odds of elevated LDL-c and abdominal obesity than those in the lowest tertile. Regarding the semi-healthy diet, higher adherence was associated with 51 % lower odds of elevated FBG (OR: 0.49, 95 % CI: 0.24-0.99). For other outcomes, no significant association was found. Conclusion: We found that T1D patients may take benefit from adherence to a semi-healthy diet with a low amount of unhealthy and Western-related foods.

Association of major dietary patterns with advanced glycation end products and high-sensitivity C-reactive protein in people with type 1 diabetes mellitus.

BACKGROUND: The associations of diet with serum levels of advanced glycation end products (AGEs) and high-sensitivity C-reactive protein (hs-CRP) have been examined in patients with type 2 diabetes mellitus (T2DM). However, data on patients with type 1 diabetes mellitus (T1DM) are limited. Therefore, this study was conducted to investigate the associations of major dietary patterns with serum levels of AGEs and hs-CRP among patients with T1DM. METHODS: A total of 229 patients with T1DM participated in this current cross-sectional study. We collected dietary data using a validated food frequency questionnaire (FFQ). The factor analysis approach was used to determine major dietary patterns. A fasting blood sample was collected from each participant to assess serum levels of AGEs and hs-CRP. The associations of dietary patterns with elevated levels of AGEs and hs-CRP were assessed using binary logistic regression. RESULTS: Patients with T1DM in the highest tertile of a Western dietary pattern had 4.32 times higher odds of having elevated AGEs than those in the lowest tertile (OR: 4.32, 95% CI: 1.86-10.05). Additionally, adherence to the Western diet was associated with 2.97 times greater odds of having elevated hs-CRP (> 3 mg/L) (OR: 2.97, 95% CI: 1.22-7.24) in these patients. Such positive associations were not observed for unhealthy and traditional dietary patterns. Moreover, higher adherence to a semi-healthy diet (characterized by high consumption of white meat, whole grains, processed meat, and a low salt intake) was associated with 87% lower odds of having elevated hs-CRP (OR: 0.13, 95% CI: 0.05-0.35). However, we found no significant association between the semi-healthy diet and AGEs levels. CONCLUSION: We found that adherence to a Western dietary pattern was associated with elevated levels of AGEs/hs-CRP in patients with T1DM. Also, we discovered a significant inverse association between adherence to a semi-healthy diet and hs-CRP levels.

Risk of infection in postmenopausal women with rheumatoid arthritis and osteoporosis taking denosumab and bDMARDS.

Background: There is no clear consensus regarding the potential of denosumab for increasing the risk of infection in patients who concurrently receive biologic disease-modifying anti-rheumatic drugs (bDMARDs). In this study, we compared the rate of infection in postmenopausal women with rheumatoid arthritis who received concurrent bDMARDs and denosumab with those who received bDMARDs alone. Methods: In a case-control study, postmenopausal patients with a confirmed diagnosis of rheumatoid arthritis who received concurrent bDMARDs and denosumab for at least one year were identified and included as the case group (n=40). A total of 44 age-matched postmenopausal rheumatoid arthritis women who received bDMARDs alone were included as the control group of the study. Using a chi-squared test, the incidence of bacterial or viral infections was extracted from the patients' profiles and compared between the two study groups. Statistical analyses were performed by SPSS for Windows, version 16 (Chicago, Illinois, USA). A p-value of fewer than 0.05 was regarded as significant. Results: The clinical and demographic characteristics of the patients of the two study groups were not significantly different. In total, four infections were recorded in the present series, two infections in each group. Accordingly, the rate of infection was 4.5% in the bDMARDs alone group and 5% in bDMARDs + denosumab group. This difference was not statistically significant (p=0.655, 95% CI: 0.121-6.742). Three out of four infections were herpes zoster infection. The other one was osteomyelitis of the first metatarsal bone, which occurred in the bDMARDs+denosumab group. None of the infections needed a hospitalization of IV antibiotics. Conclusion: The risk of infection is comparable between postmenopausal osteoporotic women with rheumatoid arthritis who receive bDMARDS alone and those who receive bDMARDS in combination with denosumab.

Diabetes Management during the COVID-19 Pandemic: An Iranian Expert Opinion Statement.

The coronavirus infection is an evolving pandemic with high morbidity and mortality, especially in people with comorbidities. The case fatality rate (CFR) is 9.2% in the presence of diabetes, while it is 1.4% in those without any comorbidity. Diabetes is a prevalent disease globally; hence, healthcare professionals are highly concerned about severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic progression. Current evidence does not support higher incidence of coronavirus disease 2019 (COVID-19) in people with diabetes (PWD). However, people with diabetes are considered high risk for developing complications. Optimal metabolic control is a challenging concept, especially in the presence of an acute and severe respiratory viral infection. In this consensus, we considered the challenging issues in management of patients with diabetes during the COVID-19 pandemic. The consensus covers various aspects of outpatient as well as inpatient care based on the current evidence.

Effects of vitamin D optimization on quality of life of patients with fibromyalgia: A randomized controlled trial.

Background: Numerous studies have been conducted to evaluate the frequency of hypovitaminosis D in patients with fibromyalgia syndrome (FMS) and its association with FMS symptoms. This study aimed at assessing the effect of hypovitaminosis D on the symptoms and quality of life of patients with fibromyalgia. Methods: A total of 74 FMS patients with hypovitaminosis D were randomly assigned into group A (Trazodone 25 mg at bedtime + vitamin D 50 000 IU weekly) and group B (Trazodone 25 mg at bedtime + placebo). Serum vitamin D level, Widespread Pain Index (WPI), Fibromyalgia Impact Questionnaire (FIQ), Pittsburgh Sleep Quality Index (PSQI), and Short Form Health Survey (SF-36) were used at the beginning of the treatment and 4 and 8 weeks post treatment. Results: Significant improvements were observed in WPI, FIQ, and PSQI scores in both groups. Moreover, combination of vitamin D and Trazodone resulted in significant improvement of SF-36 scores compared to Trazodone therapy. Improvement in pain-related indices including the WPI and the physical component score (PCS) fraction of SF-36 was more noticeable in vitamin D/Trazodone combination therapy. Conclusion: This study suggests that vitamin D supplementation has significant therapeutic benefits in the management of FMS, especially in pain reduction of patients with fibromyalgia. According to our results, a combination of vitamin D supplements and a conventional antidepressant, when given to vitamin D-deficient fibromyalgia patients, could significantly improve both physical and psychological symptoms.

A study of the value of trabecular bone score in fracture risk assessment of postmenopausal women.

OBJECTIVE: Trabecular Bone Score (TBS) is an index of bone microarchitecture that provides additional skeletal information to areal Bone Mineral Density (aBMD). Recently TBS data has been used to optimize the Fracture Risk Assessment Tool (FRAX) predictive value. The aim of this study was to evaluate the clinical value of TBS on FRAX algorithm. MATERIALS AND METHODS: Among total of 358 postmenopausal Iranian women (mean age 61.3 ± 9.5 years) tested for aBMD and TBS, 184 osteopenic women were identified. Thoracolumbar spine X-ray done in all participants revealed twenty-one vertebral fractures. For the osteopenic group, FRAX and TBS adjusted FRAX (FRAX-TBS) were calculated and compared. RESULTS: Mean TBS of the patients was 1.31 (±0.11). A significant correlation was found between TBS and spine aBMD (r = 0.50, p < 0.001) and TBS and femoral neck aBMD (r = 0.37, p < 0.0001). A strong positive correlation was observed between aBMD adjusted FRAX and FRAX-TBS in predicting the risk of major osteoporotic fracture (r = 0.90, p < 0.0001), and hip fracture (r = 0.97, p < 0.0001). According to the area under the receiver operating characteristics curve, the predictive value of the three different models using aBMD, TBS, and combination of aBMD and TBS were similar (0.765, 0.776, and 0.781, respectively; p = 0.19). The proportion of the women needed treatment remained unchanged using FRAX or FRAX-TBS. CONCLUSION: This study showed no clinical benefit for TBS in postmenopausal women. Adding TBS data to aBMD or FRAX neither improved aBMD predictive value for vertebral fracture nor changed the decision on treatment based on FRAX.

GABRIC Diabetes School: an innovative education centre for people with diabetes.

Diabetes prevalence and deaths attributable to diabetes continue to rise across globally. Diabetes Self-Management Education and Support (DSME/S) is a critical resource designed to help people with diabetes (PWD) successfully selfmanage their disease; however, its utilization is too low. In the Islamic Republic of Iran, there are currently limited structured educational programmes and no national standards for DSME/S protocol. In response to this, the GABRIC Diabetes Education Association (GDEA) has been developed as a school for diabetics, which has a comprehensive DSME/S programme for PWD with 18 distinct courses on 5 levels for 8 target groups. In addition, GABRIC has developed a database registry with more than 100 000 members throughout the country, of whom 95% are diabetic with a proportion of 82% Type 2 diabetes and 13% Type 1 diabetes. The success of the GABRIC school model results is yet to be investigated through study trials, and offers a fruitful line of research.

Longstanding hypoparathyroidism in a fifty-two-year-old woman misdiagnosed as spondyloarthropathy.

INTRODUCTION: Hypoparathyroidism might cause various musculoskeletal findings, resembling Spondyloarthropathies. CASE PRESENTATION: We described a 52-year-old woman, diagnosed as a case of undifferentiated spondyloarthropathy for ten years, who was unresponsive to classic anti-inflammatory therapies. She developed anterior ischemic optic neuropathy and had elevated muscle enzymes during the course of disease. On a routine checkup, marked hypocalcemia and suppressed parathyroid hormone levels were found. Calcium and calcitriol therapy led to clinical and laboratory improvement. CONCLUSIONS: This case emphasizes the importance of recognizing rheumatic manifestations of hypoparathyroidism to preclude unnecessary treatments. Serum calcium should be included in the diagnostic workup of these patients.
