Efficacy and safety of empagliflozin: a "real-world" experience from Saudi Arabia.

BACKGROUND: Sodium-glucose cotransporter 2 (SGLT2) inhibitors are new agents for treating type 2 diabetes. In addition to the glycemic benefits, these agents provide cardiorenal protection in patients with diabetes and without diabetes. There is consistent evidence that these agents increase the risk of genitourinary infections and dehydration, but randomized controlled trials have not included patients from the Middle East. OBJECTIVES: Determine the efficacy and safety of empagliflozin, specifically whether the genitourinary infection risk differs in our population and whether there is an increased risk of dehydration, ketoacidosis, hypoglycemia, and hospitalization with fasting. DESIGN: Retrospective review of medical records. SETTINGS: Department of medicine at tertiary care center. PATIENTS AND METHODS: We reviewed the electronic records of patients with type 2 diabetes who took empagliflozin from 1 December 2018 to 30 November 2019. We collected safety and efficacy data for 12 months from the initiation of treatment. MAIN OUTCOMES MEASURES: Glycemic and weight loss efficacy, risk of hospitalization due to hypoglycemia, dehydration, and genitourinary infections. SAMPLE SIZE: 637 patients. RESULTS: We observed an improvement in glycated hemoglobin, a 4.2% weight loss, improved left ventricular function, stable serum creatinine, and reduced albuminuria. Our patients did not have an increased risk of genitourinary infections, hypoglycemia, dehydration, ketoacidosis, or hospitalizations. Fasting did not increase the incidence of adverse events. CONCLUSIONS: Empagliflozin is safe and effective in our local population. We hypothesize that glycosuria induced by empagliflozin is not the sole contributor to the increased risk of genitourinary infections. Local hygiene and circumcision might reduce this risk. Empagliflozin can be used safely during fasting. LIMITATIONS: Retrospective design. CONFLICT OF INTEREST: None.

Assessment of pain in patients with primary immune deficiency.

BACKGROUND: Primary immune deficiency (PID) patients may develop acute or chronic pain. Pain has not been studied in this population until now. OBJECTIVES: This study systematically assessed the pain of various durations in PID patients using validated pain questionnaires. SUBJECTS AND METHODS: A Short-Form McGill Pain Questionnaire (SF-MPQ), already validated in the Arabic language, was used to ascertain the characteristics and severity of pain. Additionally, an Arabic version of the Neuropathic Pain Questionnaire-Short Form (NPQ-SF) was employed to evaluate neuropathic pain in the same group of patients. RESULTS: Forty-six patients participated in the study. The mean age of the patients was 25 years. The most commonly diagnosed PID was a common variable immune deficiency (32.6%), followed by severe combined immune deficiency (19.57%). Based on the SF-MPQ, the pain was experienced by 30.4 % of the subjects who participated in the study; 57% of whom were on regular pain medications. The most common site reported for pain was the abdomen (35.7%). The mean duration of pain was 36.1 days ± 34.6 days. The most common comorbidities in these patients were bronchiectasis, followed by immune thrombocytopenic purpura, and scoliosis. None of the PID patients had significant neuropathic pain based on NFQ-SF. CONCLUSION: To the best of our knowledge, this is the first study to assess the prevalence as well as the severity and duration of pain in PID patients. There were significantly more subjects who had continuous pain. Treatment of pain in PID patients will have a significant effect on improving their quality of life.

Comparing the utility of 30- and 60-minute cortisol levels after the standard short synacthen test to determine adrenal insufficiency: A retrospective cross-sectional study.

Short Synacthen test (SST) involves measuring the baseline, 30-, and 60-minute serum cortisol levels, after injecting 250 µg of synthetic adrenocorticotropic hormone or Synacthen (ACTH). This study aimed to review the current clinical practice of performing SST to establish a standardized test protocol and to additionally test the hypothesis regarding performing the 60-minute cortisol test alone and the dependence of overall SST result on baseline cortisol level.Patients >14 years who underwent SST from January 2010 to December 2017 were included. Pearson's chi-square cross-tabulation was used to identify individuals with inconsistent 30- and 60-minute serum cortisol test results. Logistic regression analysis was performed to predict normal responses based on the baseline cortisol value.Of the 965 patients identified from pharmacy, medical, and laboratory records, 849 were included. Mean baseline, 30-, and 60-minute cortisol levels after ACTH injection were 394 ±â€Š286.58, 722 ±â€Š327.11, and 827 ±â€Š369.30 nmol/L, respectively. Overall, 715 (84%) and 134 (16%) patients had normal and abnormal responses, respectively. Primary and secondary adrenal insufficiency was diagnosed in 10% and 35%, respectively, while ACTH levels were not measured in 55% of the patients. Overall, 9.49% (n = 72) of the patients had a suboptimal response at 30 minutes, but reached the threshold value of 550 nmol/L at 60 minutes. This particular subgroup's mean change (240 nmol/L) in cortisol level from baseline to 30-minute was higher than that observed in patients with abnormal response at both time-points (mean change, 152 nmol/L). No patient with 30-minute optimal responses had 60-minute suboptimal responses. The baseline serum cortisol threshold of ≥226 nmol/L had 80% sensitivity, 71% specificity, and 93% positive predictive value for detecting a normal SST (P-value < .0001).Relying on a 60-minute cortisol level can identify all normal and abnormal responses, while relying on 30-minute cortisol level alone may produce false-positives. Additionally, a baseline cortisol level of ≥226 nmol/L is a reliable threshold for determining adequate adrenal function, particularly with a low pretest hypoadrenalism probability.

Idiopathic pleuroparenchymal fibroelastosis: The first case to be managed with a successful lung transplant at King Faisal Specialist Hospital and Research Center, Riyadh.

Idiopathic Pleuro-Parenchymal Fibroelsatosis (PPFE) is a rare, progressive and recently recognized subtype of idiopathic interstitial lung disease with no recorded successful treatment other than lung transplant. We report a case of idiopathic pleuroparenchymal fibroelastosis from the Middle East, managed successfully by bilateral lung transplant performed on a 26 year old Saudi male.
