Attenuation of Human Growth Hormone-Induced Rash With Graded Dose Challenge.

Adult growth hormone (GH) deficiency is rare and requires replacement with extrinsic/synthetic injection. GH hypersensitivity has been reported; specifically, atopic patients may develop rashes from somatotropin therapy. Allergic and non-allergic skin reactions to recombinant human GH are uncommon and infrequently reported. We describe a graded-dose challenge with intravenous Norditropin® in a 65-year-old atopic adult woman who developed a severe whole-body rash with Norditropin FlexPro® administration on several occasions but was negative on skin-prick testing to Norditropin® percutaneously and intradermally, but the patch testing was positive for gold and nickel. The patient was registered as a direct admission to the emergency room at a university hospital for a rapid antigen coronavirus disease 2019 (COVID-19) testing after having received two COVID-19 vaccinations and re-testing four months after vaccination. She was then directly admitted to a non-COVID-19 intensive care unit with direct bedside supervision by a registered nurse and a physician board certified in internal medicine, allergy/immunology, and pulmonary diseases. The patient brought a Norditropin® pen which our pharmacy team attached to a compatible syringe for dilutions. A graded dose challenge at a final dosage of 0.1 mL was performed and the patient was monitored for allergic and other adverse drug reactions, which did not occur. At the time of writing this case report, the patient has been maintained on Norditropin FlexPro® 0.1 mL and has not experienced any adverse reactions, including recurrent skin eruptions. The case presented is the first to describe a patient who successfully tolerated a graded dose challenge of an adult patient to GH replacement therapy (as Norditropin®) under supervision in an intensive care unit, whereas prior to reporting of this case, a graded dose challenge to GH replacement therapy had only been successfully performed in a child using another formulation of somatotropin (Humatrope®). Hence, this case lends support that graded dose challenge with somatotropin analogs may be considered for patients with isolated GH deficiency such as in the case presented here.

Pediatric COVID toes and fingers.

The emergence of the coronavirus disease 2019 (COVID-19) worldwide pandemic has been associated with a new constellation of cutaneous features in children. Among the unusual dermatologic presentations are the so-called COVID toes, inflammatory nodules of the feet and toes, sometimes involving the hands and fingers. These lesions mimic acral pernio, the synonym being chilblains. Unlike adult patients with COVID toes, children are less likely to manifest symptomatic COVID-19. Although a few studies have found some linkage to COVID-19 through the serum IgA or IgG severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein, other studies have no demonstrable linkage suggesting that barefoot children in cold weather develop such lesions. It appears that the chilblain-like lesions related to the period of the COVID-19 pandemic may reflect a brisk immune response portending a good prognosis and perhaps some form of innate immunity. The possible need to screen for coagulopathy is unclear, but this has been suggested in one report. Until we fully understand the pattern of immune response to COVID-19, questions may persist as to how disease manifestations are linked to SARS-CoV-2 exposures.

Influenza Vaccination Quality Improvement as a Model for COVID-19 Prophylaxis.

INTRODUCTION: Many comparisons have been made on the effect and impact of COVID-19 on influenza pandemics of history. Therefore, it is reasonable to infer that the strategies utilized by healthcare providers to improve influenza vaccination rates can similarly be applied to the administration of a COVID-19 vaccine. The purpose of this study was to determine the rationale of low influenza vaccination rates in an urban allergy clinic and how to improve patient education and knowledge regarding the importance of influenza vaccination. A three-year comparison of interventions is presented as well as its application to future COVID-19 vaccinations. METHODS: This study was performed at an outpatient allergy and clinical immunology practice (MSBI) with hospital affiliation in New York City, New York. A quality improvement medical committee was formed to optimize influenza vaccination rates to greater than 71% and established standardized protocols regarding patient intake workflows, vaccine counseling, and documentation. Patient records from four providers were used for this study to compare pre-and post-intervention rates. RESULTS: 984 patients met inclusion criteria, with a normal distribution of ages (18-80), race, and sex. Average vaccination rates prior to the intervention were 9.25-13.60%. The average vaccination rate after the intervention was 91.34%. DISCUSSION: The MSBI quality improvement study identified key areas to address in improving influenza vaccination rates. Vaccine hesitancy, public misinformation, and ambivalence surrounding vaccination with egg allergies or during a subcutaneous immunotherapy injection were all topics addressed during the 2018-2019 intervention year. Additional attention was also put toward provider education and standardization of documentation. Shared decision making and intensive education/outreach efforts are needed by physicians and patients alike to overcome vaccine hesitancy. In comparing this to upcoming COVID-19 vaccine challenges, similar barriers will likely also need to be addressed. Greater research is needed to understand patient motivations regarding hesitancy specific to the COVID-19 vaccine. CONCLUSION: As evidenced in the yearly battle with influenza and now the COVID-19 pandemic, it has become essential to identify and implement multi-level strategies to maximize vaccination rates, especially amid a global pandemic. With COVID-19 vaccines reaching emergency approval stages, it is important for healthcare providers to start creating workflows and strategies to address patient inquiries. The influenza vaccination quality improvement project presented here can be used as a guideline for future evaluations of COVID-19 vaccination efforts.
