Assessing the Vaccination Status and Barriers to Influenza, Pneumococcal, and COVID-19 Vaccination Among Moroccan Patients With Chronic Inflammatory Rheumatic Disease.

OBJECTIVE: To evaluate the vaccination coverage of patients with chronic inflammatory rheumatic disease (CIRD) against influenza, pneumococcus, and COVID-19 and to determine, per the patients' point of view, the possible factors related to vaccination hesitation and/or refusal. METHODS: A cross-sectional study carried out by the vaccination working group of the Moroccan Society of Rheumatology, including patients with CIRD in Morocco. Information about vaccination coverage and reasons for non-vaccination against influenza, pneumococcal infection, and COVID-19 was collected. RESULTS: This survey included 230 patients (mean age of 46.9 +/-13.89 years; 68.7% females) affected by CIRD (rheumatoid arthritis 53%, spondyloarthritis 39.6%, psoriatic arthritis 7%). The study shows a significant lack of influenza and pneumococcal vaccination in CIRD patients, with vaccination coverage against influenza, pneumococcal infection, and COVID-19 at 2.2%, 0.4%, and 80.9%, respectively. The main reason for non-vaccination against influenza and pneumococcus was related to the absence of recommendations by their doctors (77%, 87%, p = 0.04). Additionally, the primary reason for non-vaccination against COVID-19 was the fear of the vaccine's side effects (51%, p = 0.0001), mainly a flare-up of CIRD (44%, p = 0.001). CONCLUSION: This survey shows a lack of influenza, pneumococcal, and COVID-19 vaccination in CIRD patients. The principal actions to improve vaccination should aim to educate patients and encourage rheumatologists to vaccinate their patients.

Knowledge, Attitudes, and Practices of Moroccan Community Rheumatologists' Regarding the Management of Non-radiographic Axial Spondyloarthritis: A National Cross-Sectional Study.

Introduction Non-radiographic axial spondyloarthritis (nr-axSpA) is within the spectrum of axial spondyloarthritis (axSpA). The emergence of the nr-axSpA concept, defined by the absence of significant erosive damage to the sacroiliac joints, has prompted numerous initiatives aimed at enhancing the early detection and management of this condition. The aim of the study was to assess the knowledge, attitudes, and practices related to the diagnosis and management of nr-axSpA by rheumatologists in Morocco. Methods We conducted a cross-sectional online survey among the rheumatologist community in Morocco. Rheumatologists received via e-mail a structured Google Forms (Google Inc., Mountainview, CA) questionnaire divided into four sections: sociodemographic data of rheumatologists, knowledge, attitudes, and practices related to the diagnosis and treatment management of nr-axSpA. Results A total of 110 rheumatologists (mean age of 44±13 years, 77.3% females, median professional experience of 12 years (4, 75; 26.25 years)) participated in the survey (response rate of 25%). Most responders reported a diagnosis delay issue in spondyloarthritis (SpA) (93.6%); 70.9% of rheumatologists incorrectly regarded the 2009 Assessment of Spondyloarthritis International Society (ASAS) classification criteria for axSpA as diagnostic criteria. Rheumatologists' awareness of recommended magnetic resonance imaging (MRI) sequences for detecting sacroiliac joint inflammation and structural changes in SpA varied significantly, from 69.1% to 14.5%. Their knowledge of additional subchondral edema cases in these joints, beyond SpA, ranged from 48.2% to 87.3%. Almost all rheumatologists believed that the use of sacroiliac MRI would contribute to the early diagnosis of axSpA (97.3%) but could also lead to false positive diagnoses, according to 47.3% of rheumatologists; 73.6% believed that incorrectly using the 2009 ASAS classification criteria as diagnostic criteria in nr-axSpA could also result in false-positive diagnoses. In their practice, 2009 ASAS classification criteria were used as diagnostic criteria in axSpA by 39.1% of rheumatologists. Of the total participants, 91.8% indicated that they approach nr-axSpA similarly to radiographic axial spondyloarthritis, with disparities in recommendations of biological therapies. Conclusion Our survey provides insight into the current status of nr-axSpA management among Moroccan rheumatologists. It also addresses concerns regarding the risk of false positive diagnoses when using the 2009 ASAS classification criteria for axSpA as diagnostic criteria by rheumatologists and the potential risk of misdiagnosis associated with excessive reliance on MRI, despite its utility for early diagnosis.

Active tuberculosis infection in moroccan patients with rheumatic diseases under biologic therapy: A multicenter national study.

Background: The aim of this study was to evaluate the prevalence of active tuberculosis (TB) infection in Moroccan patients with rheumatic diseases under biologic therapy, and to describe the demographic characteristics of these patients as well as to explore potential risk factors. Methods: This 14-year nationally representative multicenter study enrolled Moroccan patients with rheumatic diseases who had been treated with biologic therapy. Patient medical records were reviewed retrospectively for demographic characteristics, underlying rheumatic diseases, associated comorbidities, and TB-related data. Results: In total, 1407 eligible patients were studied, detailed records were obtained for only 130 patients; 33 cases with active TB were identified at an estimated prevalence rate of 2.3%. The mean age was 42.9 ± 12 years and 75.8% were males. Ankylosing spondylitis accounted for 84.8% of active TB cases, and the majority of the cases (31/33) occurred among antitumor necrosis factor-alpha (TNF-α) users. A total of 8 out of 33 patients were positive at initial latent TB infection (LTBI) screening by tuberculin skin test and/or interferon-gamma release assay. Consumption of unpasteurized dairy products (odds ratio [OR], 34.841; 95% confidence interval [CI], 3.1-389.7; P = 0.04), diabetes (OR, 38.468; 95% CI, 1.6-878.3; P = 0,022), smoking (OR, 3.941; 95% CI, 1-159.9; P = 0.047), and long biologic therapy duration (OR, 1.991; 95% CI, 1.4-16.3; P = 0.001) were identified as risk factors for developing active TB. Conclusion: Moroccan patients with rheumatic diseases under anti-TNF-α agents are at an increased TB risk, especially when risk factors are present. Strict initial screening and regular monitoring of LTBI is recommended for patients living in high TB prevalence areas.

Effects of kinesiotaping on disability and pain in patients with rotator cuff tendinopathy: double-blind randomized clinical trial.

BACKGROUND: Kinesiotaping (KT) is widely used in several musculoskeletal disorders particularly in shoulder pain. However, literature shows controversial results regarding the effect of KT on shoulder pathology. The aim of this study was to assess the clinical effects of KT in the short term on rotator cuff tendinopathy (RCT). METHODS: A randomized controlled double-blind clinical trial was conducted. The sample consisted of 50 subjects (25 per group). Patients were randomly assigned to the KT group (to receive therapeutic KT application) or to the placebo group (to receive sham KT application). Taping was applied every 4 days, a total of three times during the study period. We assessed the patients at baseline, at the end of taping period (D12), and at one-month post-taping (D30). Primary outcome was assessed through the Arabic version of the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH). Secondary outcomes were assessed through Visual Analogue Scale (VAS) for pain intensity at rest (VASr), during active movement (VASm), and at night (VASn). RESULTS: There were no significant differences between the two groups in the demographic and clinical characteristics and the pre-test scores. Results of repeated measures ANOVA showed significant improvement in DASH scores and in VAS for pain (at rest, during active movement and at night) from D12 in both groups. The use of ANCOVA, controlling for pre-test scores, showed no significant differences between groups, except for VASm at D30. CONCLUSION: This study showed that the standardized therapeutic KT used for shoulder pain was not superior to a sham KT application in improving pain and disabilities in patients with RCT. TRIAL REGISTRATION: The study was retrospectively registered on Pan African Clinical Trial Registry (identification number: PACTR202007672254335) on 21/07/2020. https://pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=12200.

Oral Hygiene Status in Rheumatoid Arthritis Patients and Related Factors.

OBJECTIVES: To evaluate oral hygiene status in Rheumatoid arthritis (RA) patients, to analyse possible related factors, and to investigate the role of the rheumatologist in information about importance of adequate oral hygiene status in RA patients. METHODS: A cross-sectional study that included 100 consecutive RA patients (89% female, mean age 46.7 ± 11.7 years). For each patient, we recorded oral symptoms, oral hygiene status and role of rheumatologist in information on the oral hygiene status. Factors associated with regular brushing (≥2/day) were also analysed. RESULTS: Median disease duration was 8 years (4;2). Dental pain was reported by 74% of patients and bleeding by 51% of them. Regular brushing was noted in 45% of patients. The use of a correct brushing method was noted in 14% of cases. Two patients reported visiting a dentist regularly. Information explaining that poor oral hygiene has a negative impact on RA was delivered by rheumatologist to 11 patients. Regular brushing of teeth was recommended by rheumatologist to 8 patients and 10 patients were advised by their rheumatologist to consult a dentist. Regular brushing was more important in women (48,3% vs 18,2%; p=0.05) and in the literate patients (57,6 vs 31,2%, p<0.01). No association was found between regular brushing, Disease Activity Score 28 (DAS28) and health Assessment Questionnaire (HAQ). CONCLUSION: This study illustrates bad oral hygiene status in RA patients, which seems more important in men and illiterate patients. It also highlights poor information given by the rheumatologist.

One-year direct costs of biological therapy in rheumatoid arthritis and its predictive factors: data from the Moroccan RBSMR registry.

The aim of the study was to estimate the annual direct costs of biological therapies in rheumatoid arthritis (RA), and to establish possible factors associated with those costs. The main data source was the Moroccan registry of biological therapies in rheumatic diseases (RBSMR Registry). We included patients with available 1-year data. Variables related to socio-economic status, disease and biological therapy were collected. Direct costs included prices of biologics, costs of infusions, and subcutaneous injections. Differences in costs across groups were tested by Mann-Whitney and Kruskal-Wallis tests. Correlations analysis was performed in search of factors associated with high costs. We included 197 rheumatoid arthritis patients. The mean age was 52.3 ± 11 years, with female predominance 86.8%. Receiving one of the following therapies: rituximab (n = 132), tocilizumab (n = 37), or TNF-blockers (n = 28). Median one-year direct costs per patient were €1665 [€1472-€9879]. The total annual direct costs were € 978,494. Rituximab, constituted 25.7% of the total annual budget. TNF-blockers and tocilizumab represented 27.3% and 47% of this overall budget, respectively. Although the costs were not significantly different in terms of gender or level of study, the insurance type significantly affected the cost estimation. A positive correlation was found between the annual direct cost and body mass index (r = 0.15, p = 0.04). In Morocco, a developing country, the annual direct costs of biological therapy are high. Our results may contribute to the development of strategies for better governance of these costs.

Pre-extensively drug-resistant tuberculosis spondylodiscitis in an immunocompetent patient: a case report.

Pre-extensively drug resistant tuberculosis (pre-XDR-TB) has been an area of growing concern, and posing a threat to global efforts of TB control. We report a case of PreXDR-TB spondylodiscitis with resistance to a Fluoroquinolone, in an immunocompetent patient under antibacillary treatment for pleural tuberculosis, managed with drug sensitivity-based second-line antituberculous drug regimen. Our case shows the challenges of the diagnostic and management of Drug-resistant TB spondylodiscitis.

Cross-cultural adaptation and validation of the Arabic version of the functional index for hand osteoarthritis.

BACKGROUND: The Functional Index of Hand Osteoarthritis (FIHOA) is a clinically and methodologically validated score used to assess functional impact in patients with hand osteoarthritis (OA). The aim of the study was to translate the FIHOA into classical Arabic, and to validate the psychometric properties of the translated version. METHODS: The FIHOA was translated into Arabic (FIHOA-AR) according to cross-cultural adaptation guidelines. The FIHOA-AR was administrated to patients diagnosed with hand OA according to the criteria of the American College of Rheumatology (ACR). A 5-day test-retest reliability and internal consistency study was performed using the intra-class correlation coefficient (ICC) and the Cronbach's alpha coefficient. External validity was measured by correlations between FIHOA-AR, hand pain visual analog scale (VAS) and the Health Assessment Questionnaire (HAQ). RESULTS: The sample consisted of 101 patients with hand OA. The obtained ICC > 0.9 and Cronbach's alpha of 0.93 indicated excellent reliability and internal consistency respectively. The evaluation of external validity showed strong correlation with hand pain VAS (r = 0.88, p < 0.001), and strong correlation with HAQ score (r = 0.86, p < 0.001). CONCLUSION: The FIHOA-AR is a reliable and valid score to assess functional disability in Arabic- speaking patients with hand OA.

Management of gout by Moroccan rheumatologists: a Moroccan Society for Rheumatology National Survey.

To assess the modalities and current practices in gout management reported by Moroccan rheumatologists. We performed a cross-sectional online survey using a questionnaire e-mailed to 360 rheumatologists included 30 multiple-choice questions. 105 rheumatologists responded to the survey with 29% of response rate. The number of gout patients seen per month was five (3-9); they were referred in 58.7% by a general practitioner. The clinical presentation of gout patients was dominated by gout crisis in 71%, and the association gout crisis and gouty arthropathy accounted for 19% of severe forms. 40% of rheumatologists apply the 2015ACR/EULAR classification criteria. Obesity accounted for 85.7% of the associated comorbidities. The most commonly prescribed Urate-lowering therapy (ULT) was allopurinol in 81.3% (± 12). 48% of rheumatologists reported starting allopurinol at 200 mg daily and associated it with colchicine during the first 6 months by 33.3%. The determination of uric acid levels was monitoring in 76.2% every 3 months. Administration of ULT to asymptomatic hyperuricemia was found in 69.5% when patients had renal complications, while only 14.3% recommended dietary and lifestyle measures. The median duration for therapeutic education was 15 min (10, 20). In 96.2%, the education of the patient was done orally. 93.3% of rheumatologists inform their patients on how to manage a gout attack, and 96.2% on the measures of hygiene and diet has adopted. Our survey gives an insight into the elements that should be improved in the management of gout by the Moroccan rheumatologists. It highlights the need to standardize the management of gout, hence the importance of developing Moroccan recommendations on gout.

Perception of Sleep Disturbances due to Bedtime Use of Blue Light-Emitting Devices and Its Impact on Habits and Sleep Quality among Young Medical Students.

INTRODUCTION: The use of blue light-emitting devices (smartphones, tablets, and laptops) at bedtime has negative effects on sleep due to light stimulation and/or problematic excessive use. We aimed to evaluate, among young medical students, if the perception of sleep disturbances due to bedtime use of these devices is consistent with healthier habits and a better sleep quality. MATERIALS AND METHODS: 294 medical students in medicine and pharmacy from the Faculty of Medicine and Pharmacy of Rabat, Morocco, took part in this anonymous and voluntary cross-sectional study and answered an electronic questionnaire. Student and Mann-Whitney U tests were used to compare variables between 2 groups based on their perception of sleep disturbances. The level of significance was p ≤ 0.05. RESULTS: 286 students (97.3%) used a blue light-emitting smart device at bedtime before sleep, and sleep quality was poor (Pittsburgh Sleep Quality Index, PSQI > 5) in 101 students (35.3%). The perception of sleep disturbances due to this night usage was reported by 188 of them (65.7%). In this group, 154 (81.9%) used their device with all the lights turned off in the room (p=0.02), 34 (18.1%) put devices under pillows (p=0.04), 114 (60.6%) interrupted sleep to check messages (p < 0.001), and the mean duration use of these technologies at bedtime was 2 h ± 23 min per night (p=0.02). Also, the mean sleep duration was 6.3 hours ± 1.25 (p=0.04), 119 (63.3%) presented fatigue on waking more than one time per week (p=0.04), and 76 (40.4%) presented poor sleep quality (75.2% of the students with PSQI > 5) (p=0.005). CONCLUSIONS: Despite the perception of sleep disturbances due to bedtime use of blue light-emitting devices, unhealthy sleep habits tend to be frequent in young medical students and worrying because it is associated to significant poor sleep quality.

Knowledge, attitudes, and practice of organ donation in Morocco: A cross-sectional survey.

In any health system, public awareness of organ donation fundamentally affects the organ transplantation programs. The aim of this study was to evaluate the knowledge and perception of the people in Morocco toward organ donation as well as to identify the reasons and determinants for refusal of organ donation. This opinion survey included a representative sample of 2000 participants in Morocco, and data related to sociodemographic characteristics, knowledge and self-opinion about organ donation, and reasons behind refusal were collected. Statistical analysis showed that 55.2% of the participants were women, the median age was 21 years, and 60.8% of included participants had secondary education. Almost two-thirds of surveyed participants (62.3%) showed a low to mid-level of knowledge about organ donation and transplantation in Morocco. About half of the interviewed participants (48.8%) refused to donate their organs. Concern about risk of medical error and the belief in trafficking of procured organs were the main reasons for refusal, seen in 66% and 62% of the interviewees, respectively. Univariate and multivariate logistic regression models showed that the older, the less educated and the less informed a person is, the less he accepted organ donation. Therefore, promotion of organ donation in Morocco should involve a regular information and awareness among the general population.

Relationship between poor quality sleep, excessive daytime sleepiness and low academic performance in medical students.

Purpose: Poor quality of sleep and excessive daytime sleepiness affect cognitive ability and have a negative impact on the academic performance of medical students. This study aims to determine the prevalence of excessive daytime sleepiness, sleep quality and psychological distress as well as assess their association with low academic performance in this population. Participants and methods: A cross-sectional study was conducted among 457 medical students from the Faculty of Medicine and Pharmacy of Rabat, Morocco, who completed the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the Epworth Sleepiness Scale to determine the quality of sleep and excessive daytime sleepiness, respectively. Sociodemographic variables and psychological distress (Kessler Psychological Distress Scale) were also measured. Multivariate linear regression was performed in order to evaluate the link between low academic performance and sleep quality after adjusting for other covariates. Results: Among the included students, the median age was 20 (19; 21) years; 70.7% of the participants were females. Almost one-third of the students (36.6%) had excessive daytime sleepiness and this was more frequently observed in female students (43% vs 20.1%, <0.001). Furthermore, 58.2% of the students were poor sleepers (PSQI ≥5), while 86.4% of them had psychological distress. The bivariate analysis showed that psychological distress was associated with decreased risk of low performance (ß=0.04; 95% CI=0.005-0.07; P=0.024). Being a poor sleeper was statistically associated with poor academic performance (ß= -0.07; 95% CI=-0.14 to -0.002; P=0.04) in the multivariate analysis. In our study, daytime sleepiness was not statistically associated with academic performance. Conclusion: A poor sleep quality determined by PSQI ≥5 was related to poor academic achievement at the end of the study year in medical students.

Evaluation of Vitamin D Status in Rheumatoid Arthritis and Its Association with Disease Activity across 15 Countries: "The COMORA Study".

The aims of this study are to evaluate vitamin D status in 1413 RA patients of COMORA study from 15 countries and to analyze relationship between patients' RA characteristics and low levels of vitamin D. All demographic, clinical, and biological data and RA comorbidities were completed. The results showed that the average of vitamin D serum dosage was 27.3 ng/mL ± 15.1 [0.1-151]. Status of vitamin D was insufficient in 54.6% and deficient in 8.5% of patients. 43% of RA patients were supplemented with vitamin D and absence of supplementation on vitamin D was related to higher prevalence of vitamin D deficiency (p < 0.001). Finally, our study shows that the status of low levels of vitamin D is common in RA in different countries and under different latitudes. Absence of supplementation on vitamin D was related to higher prevalence of vitamin D deficiency. Low levels of vitamin D were associated with patients characteristics (age, BMI, and educational level), RA (disease activity and corticosteroid dosage), and comorbidities (lung disease and osteoporosis therapy). This suggests the need for a particular therapeutic strategy to improve vitamin D status in RA patients.

Evolution du concept de la qualité de vie au Maroc : cas de la polyarthrite rhumatoïde et de la spondylarthrite ankylosante

La polyarthrite rhumatoïde et la spondylarthrite ankylosante sont à la tête des rhumatismes inflammatoires chroniques (RIC). La souffrance engendrée par la douleur chronique rhumatismale, le retentissement sur le vécu journalier des patients et leur entourage, altèrent incontestablement la qualité de vie des patients. Ce travail reprend de manière succincte les études ayant abordé cet aspect chez les patients marocains souffrant de PR et de SPA. Ces travaux font l'unanimité sur la perturbation de la qualité de vie des patients marocains souffrant de ces RIC en affectant considérablement les domaines physique, psychique et social. Les études longitudinales, réalisées en particulier dans la PR, attestent de l'intérêt de la prise en charge adéquate de ces RIC pour améliorer la qualité de vie du patient marocain

Rheumatoid shoulder assessed by ultrasonography: prevalence of abnormalities and associated factors.

INTRODUCTION: The shoulder involvement in rheumatoid arthritis (RA) is common. It can be subclinical and compromise the function of the upper limb. Musculoskeletal ultrasonography can detect subclinical abnormalities in rheumatoid shoulder. Our aim was to assess the prevalence of ultrasound abnormalities in rheumatoid shoulder, and investigate their association with different parameters. METHODS: Cross-sectional study including 37 patients with RA, meeting the ACR/EULAR 2010 classification criteria, who were enrolled during a month. A questionnaire with sociodemographic, clinical and laboratory data was filled in for all patients. Ultrasound evaluation was performed by a single experienced operator. For each patient, both of shoulders were evaluated. RESULTS: Mean age was 50 years with female predominance. Median disease duration of RA was 7.5 years. All patients had a seropositive form of RA. Mean clinical DAS28 was 5.1. Mean HAQ was 1.2. Thirty-one (83.8%) patients had involvement of the shoulder: unilateral in 9(24.3%) cases and bilateral in 22(59.5%) cases. Synovitis was found in 16(43.2%) patients with Doppler in 4 (10.8%) cases. Sub-acromial bursitis was noted in 14 (37.8%) cases and the effusion in 20 (54.1%). Synovitis was noted especially in elderly individuals (p: 0.01). The Doppler was visualized in elderly patients (p: 0.01), with a shorter disease duration (p: 0.02) and with a high SDAI (p: 0.006). US inflammatory findings in anterior recess of glenohumeral joint were linked to a higher synovial index (p: 0.03) and a higher level of rheumatoid factor (p: 0.01). CONCLUSION: 59.5% of our RA patients had bilateral involvement of the shoulder which was related to the disease activity. Ultrasound should be a systematic tool to look for the involvement of this joint in RA patients.

Reliability and validity of CDAI and SDAI indices in comparison to DAS-28 index in Moroccan patients with rheumatoid arthritis.

BACKGROUND: Clinical disease activity index (CDAI) and simplified disease activity index (SDAI) are useful tools for the evaluation of disease activity in patients with rheumatoid arthritis (RA), but have not been comparatively validated in Moroccan population. Therefore, this study was designed to assess validity and reliability of CDAI and SDAI in comparison to disease activity score-28 joints (DAS-28) in Moroccan patients with RA. METHODS: Patients with RA were included in a cross-sectional study. Patient characteristics and RA were collected. The disease activity was assessed by DAS-28, CDAI and SDAI. Patients were splitted into groups of remission, low, moderate and high activity on the basis of predefined cut-offs for DAS-28, CDAI, and SDAI. A Spearman correlation between composite indexes and inter-group comparison of the indexes were performed. Using DAS-28 as a gold standard, the Receiver operator characteristic (ROC) curve was used to assess the performance of a screening test at different levels. RESULTS: The study was conducted with 103 patients of female predominance (87.4%). Mean age was 49.7 ± 11.4 years. Median disease duration was in the order of 8 years [3-14]. There was an excellent correlation between DAS-28 and CDAI (r = 0.95, p <0.001), CDAI and SDAI (r = 0.90, p <0.001), and DAS-28 and SDAI (r = 0.92, p <0.001). There was a good inter-rater alignment between the DAS-28 and CDAI (Weighted kappa =0.743) and there was a moderate inter-rater alignment between the DAS-28 and SDAI (Weighted kappa =0.60), and also between the SDAI and CDAI (Weighted kappa = 0.589). There was no statistically significant difference between AUROC of CDAI and SDAI as both were performed equally well. DISCUSSION: This study is the first Moroccan case study to compare the performance of both CDAI and SDAI in evaluation of disease activity in patients with RA. Our study showed that there was a direct and excellent correlation between DAS-28 and CDAI, and SDAI and DAS-28. CONCLUSION: Our study shows a strong positive correlation between DAS-28, CDAI and SDAI. The cut-off values for CDAI and SDAI used in western literature can be used with minor modifications in Moroccan scenario.

Independent predictor factors of supine tachycardia in patients with type 2 diabetes mellitus.

INTRODUCTION: Supine tachycardia, frequently encountered in diabetic patients, is usually considered as an isolated diabetic complication in cardiac autonomic neuropathy. The objective of this study was to determine independent predictor factors of supine tachycardia among the clinical characteristics of type 2 diabetes mellitus. METHODS: This prospective study included type 2 diabetic patients. Supine tachycardia was considered as 10 minutes resting heart rate equal or higher than 80 beats/minutes. According to presence or not of supine tachycardia, two groups were identified: tachycardia diabetic patients and none tachycardia diabetic patients. Cardiovascular autonomic tests: deep breathing, hand-grip, and mental stress tests and blood tests were performed in all patients. Statistical analysis was done using the Student's t-test, and univariate and multivariate logistic regression analysis. RESULTS: We included 91 patients. The vagal response measured by the deep breathing test was 24.5 ± 5.7% in tachycardia diabetic patients vs 35.6 ± 6.8% in none tachycardia diabetic patients (P=0.007). The odds of supine tachycardia increased with serum creatinine (OR=1.350, 95% CI: 1.065-1.712, P=0.013) and serum uric acid levels (OR=1.034, 95% CI: 1.005-1.064, P=0.02) respectively, in diabetic patients. The prevalence of moderate renal failure was 45.5% in tachycardia diabetic patients vs. 21.6% in none tachycardia diabetic patients (P=0.034). CONCLUSION: A high frequency of supine tachycardia in type 2 diabetic patients was significantly related with an impairment of the parasympathetic nervous system but other independent predictor factors were associated to the occurrence of this supine tachycardia, such as higher levels of serum creatinine and uric acid and moderate renal failure.
