"Pre-Ramadan" telemedicine: Effect on fasting experience and glycemic control during ramadan in people with type 1 diabetes.

OBJECTIVE: People with type 1 diabetes (T1D) are advised to have a "pre-Ramadan" visit to receive the assessment and education needed to safely fast during the holy month of Ramadan. The COVID-19 lockdown has interrupted this standard of care in Muslim-majority countries where telemedicine is not well-established. Here, we examined the impact of virtual"pre-Ramadan" visits, as an alternative option to the traditional (in-person) visits, on fasting experience and glycemic control during Ramadan in people with T1D. METHOD: 151 individuals with T1D were categorized into 3 groups according to the type of"pre-Ramadan" visit that they attended in 2020: virtual (n = 50), in-person (n = 56), and no visit (n = 45). Number of days fast was broken and CGM metrics were retrospectively compared across the groups. RESULT: Patients who had a virtual"pre-Ramadan" visit were more likely to use continuous glucose monitors (CGM) than those who had no visit (61.7% and 38.6%, respectively, p < 0.05). Attending a virtual"pre-Ramadan" visit was associated with the least number of days fast was broken compared to those who had no visit (p < 0.01) or in-person visit (p = 0.02). CGM time in range (TIR) during Ramadan was the highest in those who had virtual "Pre-Ramadan" visits compared to those who had no visit or in-person visits (59%, 44%, and 47%,respectively). After adjusting for age, gender, pre-Ramadan A1c, and CGM use, the odds of fasting most days of Ramadan were highest in the virtual group [OR (CI): 9.13 (1.43, 58.22)] followed by the in-person group [3.02 (0.54,16.68)] compared to the no visit group. CONCLUSION: Virtual"pre-Ramadan" visits are effective alternative to in-person visits when managing people with T1D who plan to fast during Ramadan.

Assessment of the Effectiveness of a Protocol to Manage Dexamethasone-Induced Hyperglycemia Among Hospitalized Patients With COVID-19.

OBJECTIVE: Well-controlled glucose levels (ie, 70-180 mg/dL) have been associated with lower mortality from COVID-19. The addition of dexamethasone to COVID-19 treatment protocols has raised concerns about the potential negative consequences of dexamethasone-induced hyperglycemia. METHODS: We developed a protocol to guide the management of dexamethasone-induced hyperglycemia in hospitalized patients with COVID-19. Two of the 4 medical teams managing patients with COVID-19 at a tertiary center in Saudi Arabia used the protocol and the other 2 teams continued to manage hyperglycemia at the discretion of the treating physicians (protocol and control groups, respectively). The glycemic control and clinical outcomes in 163 patients hospitalized with COVID-19 and dexamethasone-induced hyperglycemia between July 5th and September 30th, 2020, were retrospectively compared between the 2 groups. RESULTS: Compared to the control group, the protocol group had higher proportions of patients with well-controlled glucose across all premeals and bedtime glucose readings throughout the hospital stay. The differences in glycemic control between the 2 groups were statistically significant for fasting glucose on days 4, 5, and the discharge day; prelunch glucose on the discharge day; predinner glucose on days 3, 5, and the discharge day; and bedtime glucose on day 1 (all P < .05). After adjusting for age, sex, nationality, body mass index, Charlson score, and diabetes status, patients in the protocol group were more likely to have well-controlled glucose levels compared with those in the control group. Moreover, the in-hospital mortality was significantly lower in the protocol group (12.93%) compared to the control group (29.93%) (P < .01). CONCLUSION: The implementation of a protocol to manage dexamethasone-induced hyperglycemia in hospitalized patients with COVID-19 resulted in more patients achieving well-controlled glucose levels and was associated with lower mortality from COVID-19.

COVID-19 Precautionary Measures and Type 1 Diabetes Patients in Saudi Arabia.

AIM: To minimize the spread of COVID-19, the Kingdom of Saudi Arabia (KSA) enforced a nationwide lockdown. We aimed to explore whether the manner in which Saudi patients with type 1 diabetes (T1D) manage their disease has changed during this unparalleled lockdown. METHODS: An online survey exploring the effect of lockdown on T1D outcomes was distributed among T1D patients residing in KSA during lockdown. RESULTS: A total of 1010 patients responded to the survey. Around 40% reported communicating with their physicians during lockdown. Age, level of education, residence, previous visits to diabetes education clinics, last HbA1c value, and average monthly income were all significantly associated with communication with the treating physician (p = 0.008, p < 0.001, p < 0.001, p = 0.002, p < 0.001, and p < 0.001, respectively). Age, level of education, and average monthly income were significantly associated with experiencing severe hypoglycemia (p = 0.036, p = 0.03, and p < 0.001, respectively), while average monthly income and level of education were significantly associated with experiencing diabetic ketoacidosis (DKA) (p < 0.001 and p = 0.0039, respectively); during lockdown. Patients who communicated with their physicians reported lower rates of severe hypoglycemia compared to those who did not (25.2% vs 30.7%, respectively). CONCLUSION: Age and level of education were significantly associated with communication with the treating physician, and experiencing severe hypoglycemia and DKA; in patients with T1D during the lockdown period in Saudi Arabia. Keeping two-way virtual communication channels between physicians and their T1D patients should be encouraged.

The current reproduction number of COVID-19 in Saudi Arabia: is the disease controlled?

The infectiousness of COVID-19 is high among the susceptible population, making the calculation of the reproduction number (R) an essential step to implement preventive measures. We aim to estimate COVID-19 transmission to determine if the disease is successfully controlled or extra measured should be adopted to attain this goal. The daily incidence data of COVID-19 in Saudi Arabia from March 2nd, 2020, to April 4th, 2021, were obtained from the continuously updated Saudi Ministry of Health COVID-19 repository. To get accurate estimation of the situation over the last 4 months (from December 1st, 2020, to April 4th, 2021), we calculated the weekly (every 7 days) R starting from March 2nd, 2020, and till the last week of the available data. The calculated values of R were represented as median, first quantile (Q1), and third quantile (Q3). As early as the first week of December 2020, the median R was 0.81 (0.80-0.83) which means that each existing infected case would transmit infection to only one person. This was followed by fluctuations over the next few weeks around R value of 1, reaching its highest level of 1.45 (1.42-1.47) between December 31st, 2020, and January 6th, 2021. This was followed by a relatively steady decline over the following weeks, with some till mid-March where the R values started to slightly rise again. Social distancing, protective precautions, avoiding abuse of the partial lifting, expanding the screening process, and other Saudi measures sound to be successful and should be replicated in similar communities. This measure should be continued till the vaccination process is completed, to reduce the number of contacts and to avoid uncontrolled transmission of the disease.

Biomarkers of severity and outcome among adult COVID-19 positive patients admitted to a tertiary referral hospital

Background Studies have suggested several biomarkers related to disease progression, severity and outcome of COVID-19 infection including lymphocyte count, neutrophil count, neutrophil lymphocyte ration (NLR), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), platelet count, procalcitonin (PCT), interleukin 6 (IL-6), D-dimer, troponin, creatine kinase (CK), aspartate aminotransferase (AST) and many others.1 These biomarkers were found to have significant roles in the monitoring among COVID-19 patients and will help clinicians in the management protocols. Lymphopenia was found to be associated with poor outcome and predicts disease severity among patients with COVID-19.2 These studies have reported that more severe outcomes and disease progression of COVID-19 infection occur with lymphopenic patients particularly among younger patients.2 Patients with lymphopenia were reported to have a 3-fold higher risk of developing severe COVID-19.3 Higher neutrophil count and NLR have been observed among severe COVID-19 cases as much as 5.9-fold compared to patients with mild and moderate infection.4 Marked increase in the CRP level and its association with IL6 6 also reported to predict disease severity in its early stages especially among critical patients who need more aggressive management.5 Studies have also shown the association between elevated ESR, D-dimer and IL-6 with severe COVID-19 infection among older patients aged >60 years old.6 Coagulopathies were also reported among critical COVID-19 patients and the association between thrombocytopenia and COVID-19 severity and mortality was suggested.7 The multitude of studies that were conducted to determine useful laboratory markers to predict severe outcomes and mortality form COVID-19 was exorbitant. Method We conducted a prospective cohort observational study among adult patients aged 18 years old and above who presented with signs and symptoms of COVID-19 infection (cough, fever, difficulty/shortness of breath and malaise) and history of exposure to COVID-19 at the Emergency Department (ED) of King Saud University Medical City in Riyadh, Saudi Arabia. Sub analysis of 245 COVID (+) patients with severity and mortality showed that patients who were admitted to the ICU had significantly higher levels of WBC count (p=0.030), neutrophils (p<0.001), N/L ratio (p<0.001), D-dimer (p=0.006), potassium (p=0.009), ferritin (p<0.001), CRP (p<0.001), ESR (p=0.024), cortisol (p=0.037) and longer hospital stay (p<0.001) but significantly lower levels of haemoglobin (p=0.027) and FT3 (p<0.001) compared to patients who were not admitted to the ICU.

Severe vitamin D deficiency is not related to SARS-CoV-2 infection but may increase mortality risk in hospitalized adults: a retrospective case-control study in an Arab Gulf country.

PURPOSE: As the world continues to cautiously navigate its way through the coronavirus disease 2019 (COVID-19) pandemic, several breakthroughs in therapies and vaccines are currently being developed and scrutinized. Consequently, alternative therapies for severe acute respiratory coronavirus 2 (SARS-CoV-2) prevention, such as vitamin D supplementation, while hypothetically promising, require substantial evidence from countries affected by COVID-19. The present retrospective case-control study aims to identify differences in vitamin D status and clinical characteristics of hospitalized patients screened for SARS-CoV-2, and determine associations of vitamin D levels with increased COVID-19 risk and mortality. METHODS: A total of 222 [SARS-CoV-2 (+) N = 150 (97 males; 53 females); SARS-CoV-2 (-) N = 72 (38 males, 34 females)] out of 550 hospitalized adult patients screened for SARS-CoV-2 and admitted at King Saud University Medical City-King Khalid University Hospital (KSUMC-KKUH) in Riyadh, Saudi Arabia from May-July 2020 were included. Clinical, radiologic and serologic data, including 25(OH)D levels were analyzed. RESULTS: Vitamin D deficiency (25(OH)D < 50 nmol/l) was present in 75% of all patients. Serum 25(OH)D levels were significantly lower among SARS-CoV-2 (+) than SARS-CoV-2 (-) patients after adjusting for age, sex and body mass index (BMI) (35.8 ± 1.5 nmol/l vs. 42.5 ± 3.0 nmol/l; p = 0.037). Multivariate regression analysis revealed that significant predictors for SARS-CoV-2 include age > 60 years and pre-existing conditions (p < 0.05). Statistically significant predictors for mortality adjusted for covariates include male sex [Odds ratio, OR 3.3 (95% confidence interval, CI 1.2-9.2); p = 0.02], chronic kidney disease [OR 3.5 (95% CI 1.4-8.7); p = 0.008] and severe 25(OH)D deficiency (< 12.5 nmol/l), but at borderline significance [OR 4.9 (95% CI (0.9-25.8); p = 0.06]. CONCLUSION: In hospital settings, 25(OH)D deficiency is not associated with SARS-CoV-2 infection, but may increase risk for mortality in severely deficient cases. Clinical trials are warranted to determine whether vitamin D status correction provides protective effects against worse COVID-19 outcomes.

Diabetes and Covid-19 among hospitalized patients in Saudi Arabia: a single-centre retrospective study.

BACKGROUND: Information on the clinical characteristics and outcomes of hospitalized Covid-19 patients with or without diabetes mellitus (DM) is limited in the Arab region. This study aims to fill this gap. METHODS: In this single-center retrospective study, medical records of hospitalized adults with confirmed Covid-19 [RT-PCR positive for SARS-CoV2] at King Saud University Medical City (KSUMC)-King Khaled University Hospital (KKUH), Riyadh, Saudi Arabia from May to July 2020 were analyzed. Clinical, radiological and serological information, as well as outcomes were recorded and analyzed. RESULTS: A total of 439 patients were included (median age 55 years; 68.3% men). The most prevalent comorbidities were vitamin D deficiency (74.7%), DM (68.3%), hypertension (42.6%) and obesity (42.2%). During hospitalization, 77 out of the 439 patients (17.5%) died. DM patients have a significantly higher death rate (20.5% versus 12.3%; p = 0.04) and lower survival time (p = 0.016) than non-DM. Multivariate cox proportional hazards regression model revealed that age [Hazards ratio, HR 3.0 (95% confidence interval, CI 1.7-5.3); p < 0.001], congestive heart failure [adjusted HR 3.5 (CI 1.4-8.3); p = 0.006], smoking [adjusted HR 5.8 (CI 2.0-17.2); p < 0.001], ß-blocker use [adjusted HR 1.7 (CI 1.0-2.9); p = 0.04], bilateral lung infiltrates [adjusted HR 1.9 (CI 1.1-3.3); p = 0.02], creatinine > 90 µmol/l [adjusted HR 2.1 (CI 1.3-3.5); p = 0.004] and 25(OH)D < 12.5 nmol/l [adjusted HR 7.0 (CI 1.7-28.2); p = 0.007] were significant predictors of mortality among hospitalized Covid-19 patients. Random blood glucose ≥ 11.1 mmol/l was significantly associated with intensive care admission [adjusted HR 1.5 (CI 1.0-2.2); p = 0.04], as well as smoking, ß-blocker use, neutrophil > 7.5, creatinine > 90 µmol/l and alanine aminotransferase > 65U/l. CONCLUSION: The prevalence of DM is high among hospitalized Covid-19 patients in Riyadh, Saudi Arabia. While DM patients have a higher mortality rate than their non-DM counterparts, other factors such as old age, congestive heart failure, smoking, ß-blocker use, presence of bilateral lung infiltrates, elevated creatinine and severe vitamin D deficiency, appear to be more significant predictors of fatal outcome. Patients with acute metabolic dysfunctions, including hyperglycemia on admission are more likely to receive intensive care.
