Aim To conduct a systematic review and meta‐analysis to understand the timing and factors associated with anti‐programmed cell death protein‐1 ( PD ‐1)/anti‐programmed cell death protein‐1 ligand ( PD ‐L1) inhibitor‐induced Type 1 diabetes. Methods We searched MEDLINE , EMBASE , SCOPUS and Cochrane databases (August 2000–2018) for studies of any design on immune checkpoint inhibitors. A total of 71 cases were reviewed from 56 publications. Comparisons were made using Fisher's exact and Student's t ‐tests. Results The mean ± sd age at Type 1 diabetes presentation was 61.7±12.2 years, 55% of cases were in men, and melanoma (53.5%) was the most frequent cancer. The median time to Type 1 diabetes onset was 49 (5–448) days with ketoacidosis in 76% of cases. The average ± sd HbA 1c concentration was 62 ± 0.3 mmol/mol (7.84±1.0%) at presentation. All cases had insulin deficiency and required permanent exogenous insulin treatment. Half of the cases had Type 1 diabetes‐associated antibodies at presentation, and those with antibodies had a more rapid onset ( P =0.005) and higher incidence of diabetic ketoacidosis ( P =0.02) compared to people without antibodies. Conclusions Many people developed Type 1 diabetes within 3 months of initial PD ‐1/ PD ‐L1 inhibitor exposure. People presenting with Type 1 diabetes‐associated antibodies had a more rapid onset and higher incidence of ketoacidosis than those without antibodies. Healthcare providers caring for people receiving these state‐of‐the‐art therapies need to be aware of this potential severe adverse event.
A 49-year-old female with history of hypertension, diabetes, and stage 4 chronic kidney disease presented to our facility 1 month prior for shortness of breath and hypoxia to 80%. Reverse transcription-polymerase chain reaction (RT-PCR) performed on nasopharyngeal swab resulted positive for SARS-CoV-2 infection. She was treated with supplemental oxygen and convalescent plasma during her 2 weeks admission. She was discharged on with 2 L of home oxygen. The D-dimer on admission and at the time of discharge was 1765 and 3486 ng/mL, respectively.Two weeks after discharge, she returned to our hospital with a 3 days history of excruciating diffuse abdominal pain melena and hematemesis. D-dimer was 12 444 ng/mL ,and fibrinogen was 184 mg/dL. Non-contrast CT scan revealed distended proximal jejunum with mural thickening (Fig. 1a). Exploratory laparotomy showed transmural ischemia at proximal jejunum (Fig. 1b), and 59 cm of jejunum was resected. Per the pathology report, microvascular thrombi that were partially organized within the submucosa (Fig. 2a) and cytologic changes suggestive of viral inclusion within the cytoplasm of glandular epithelial cell (Fig. 2b) were seen. Nasal swab RT-PCR test was negative for SARS-CoV-2 this time. She never had atrial arrhythmia shown on telemetry during these two admissions.Acute thromboembolic effects have been reported in COVID-19 infected patients leading to ischemic stroke, myocardial infarction,
Background The COVID-19 pandemic challenged the resilience of public health, including diagnostic testing, antiviral development and transmission prevention. In addition, it also affected the medical education of many residents and learners throughout the country. Historically, physicians undergoing their residency training were not involved in telemedicine. However, in response to the challenges faced due to COVID-19, the Accreditation Council for Graduate Medical Education (ACGME) released a provision in May 2020 to allow residents to participate in telemedicine. Method Lincoln Medical Center, located in the South Bronx of New York City, currently has 115 Internal Medicine residents, and telemedicine clinic visits have been conducted by residents since June 2020. An anonymous 25-question survey was sent to all Internal Medicine residents between August 8, 2020 to August 14, 2020. Result Of 115 residents, 95 (82.6% of the residents) replied to this questionnaire. Residents revealed feeling less confident in managing chronic diseases through telemedicine visits. The survey also shows that 83.1% of respondents prefer in-person visits during their training, 65.3% feel that the telemedicine experience will affect their future career choice, and 67.4% would prefer less than 50% of visits to be telemedicine in their future careers. Outcome The purpose of the new ACGME rules allowing telemedicine was to prevent the undertraining of residents and maintain health care for the patient during the COVID-19 pandemic. This affects residency training and the experiences of residents, which in turn can influence their future career plans.
Background: Oral vancomycin is a first line treatment for an initial episode of Clostridioides difficile infection. However, the comparative efficacy of different dosing regimens is lacking evidence in the current literature. Methods: We searched PubMed, Embase, Cochrane Library, and ClinicalTrials.gov. from inception to May 2019. Only articles published in English are reviewed. This meta-analysis compares the effects of low dose oral vancomycin (<2 g per day) versus high dose vancomycin (2 g per day) for treatment of initial Clostridioides difficile infection. Results: One randomized controlled trial and two retrospective cohort studies are included. A total of 137 patients are identified, 53 of which were treated with low dose oral vancomycin (39%) and 84 with high dose oral vancomycin (61%). There is no significant reduction in recurrence rates with high dose vancomycin compared to low dose vancomycin for treating initial episodes of non-fulminant Clostridioides difficile infection ((odds ratio (OR) 2.058, 95%, confidence interval (CI): 0.653 to 6.489). Conclusions: Based on limited data in the literature, low dose vancomycin is no different than high dose vancomycin for treatment of an initial episode of Clostridioides difficile infection in terms of recurrence rate. Additional large clinical trials comparing the different dosages of vancomycin in initial Clostridioides difficile infection are warranted.
Background: During the SARS CoV1 pandemic in 2003, there was much literature published about newly diagnosed diabetes mellitus (DM) in the patient population infected. This phenomenon has not been well established during this SARS CoV2 pandemic. In this case series, we aim to evaluate patients admitted to our facility with new onset DM who had a history of COVID-19 infection. Method: This was a single center case series that included adult patients who presented to our facility with new onset DM during June-October 2020 who had a history of SARS CoV2 positive PCR and/or positive IgG antibody to SARS CoV2. Pregnant patients were excluded. Data was collected from the hospital electronic medical records. Diagnosis of diabetes was determined in these patients via hemoglobin A1C (HbA1C) level greater than 6.5%. Results: Six patients fulfilled our diagnostic criteria. All patients were male with a median age of 54 years. The median BMI is 33.9, with 5 patients considered to be obese and 1 overweight. Other than the increased BMI, 2 patients with pre-DM and 3 patients who had a family history of DM, no other identifiable risk factors for DM were noted in this cohort. Five patients required hospitalization for HHS or DKA and 1 patient was managed as an outpatient. Median random serum glucose on presentation was 761.5 mg/dl and median HbA1C on presentation was 11.5%. Significant dosages of parenteral insulin (0.45 U/Kg) was required for hospitalized patients during their inpatient stay along with immediately after discharge to control their hyperglycemia. Glutamic Acid Decarboxylase and Islet Cell antibodies were done for 2 of the patients and were negative. Three of the patients who had follow up in 2 months showed improvement in their HbA1C (median of 7.1% [5.4–10.7]) and considerably diminished subcutaneous insulin requirement (0.2U/Kg). Two of these patients continued to follow up, and at 4 months from onset of DM, median HbA1C was 5.85% with insulin ceased. Of note, the patient who was lost to follow up was found to have an HbA1C improvement from 11.4% to 5.4% at the 2 month mark. Discussion: Both SARS CoV1 and SARS CoV2 activates the RAAS, causing insulin resistance by altering insulin signaling and increasing oxidative stress leading to dysfunction of pancreatic beta calls. The inflammatory cytokine storm response seen in COVID-19 can also decrease skeletal muscle sensitivity to insulin and decrease peripheral glucose uptake. These mechanisms may be leading to the new-onset DM noticed in our COVID-19 patients. In addition, there may be a possible immune-mediated mechanism given the matched time line between the COVID-19 antibody life span and the duration of DM. It is unknown whether this effect is permanent or temporary, although our results do support the latter. More studies that utilize a larger cohort and longer follow up are needed in order to get a better understanding of the mechanism of DM in COVID-19 infection.
