RESUMO
Patient satisfaction scores have become an integral part of the vocabulary of medical practitioners. Patient satisfaction scores are a domain far ignored, but which have recently gained prominence as patients have demanded a fair share of their own assessments of their medical caregivers. This has created a complex interplay of meeting patients' demands and satisfying their wants and needs, which at times may not completely align with the best possible approach to management and standard of care algorithms. Here we present a commentary on patient satisfaction scores and their impact on physician well-being. We present historical aspects from both patient and provider perspectives and how they vary in private versus academic practice, and create some guidance for future refinement and implementation of these scores to serve two purposes: first, to allow for optimal doctor-patient relationships; and second, to enhance overall satisfaction for the patient as well as the physician.
RESUMO
Severe combined immunodeficiency (SCID) is characterized by a severe deficiency in T cell numbers. We analyzed data collected (n = 307) for PHA-based T cell proliferation from the PIDTC SCID protocol 6901, using either a radioactive or flow cytometry method. In comparing the two groups, a smaller number of the patients tested by flow cytometry had <10% of the lower limit of normal proliferation as compared to the radioactive method (p = 0.02). Further, in patients with CD3+ T cell counts between 51 and 300 cells/µL, there was a higher proliferative response with the PHA flow assay compared to the 3H-T assay (p < 0.0001), suggesting that the method of analysis influences the resolution and interpretation of PHA results. Importantly, we observed many SCID patients with profound T cell lymphopenia having normal T cell proliferation when assessed by flow cytometry. We recommend this test be considered only as supportive in the diagnosis of typical SCID.

Chronic granulomatous disease (CGD) is a primary immunodeficiency characterized by life-threatening infections and inflammatory conditions. Hematopoietic cell transplantation (HCT) is the definitive treatment for CGD, but questions remain regarding patient selection and impact of active disease on transplant outcomes. We performed a multi-institutional retrospective and prospective study of 391 patients with CGD treated either conventionally (non-HCT) enrolled from 2004 to 2018 or with HCT from 1996 to 2018. Median follow-up after HCT was 3.7 years with a 3-year overall survival of 82% and event-free survival of 69%. In a multivariate analysis, a Lansky/Karnofsky score <90 and use of HLA-mismatched donors negatively affected survival. Age, genotype, and oxidase status did not affect outcomes. Before HCT, patients had higher infection density, higher frequency of noninfectious lung and liver diseases, and more steroid use than conventionally treated patients; however, these issues did not adversely affect HCT survival. Presence of pre-HCT inflammatory conditions was associated with chronic graft-versus-host disease. Graft failure or receipt of a second HCT occurred in 17.6% of the patients and was associated with melphalan-based conditioning and/or early mixed chimerism. At 3 to 5 years after HCT, patients had improved growth and nutrition, resolved infections and inflammatory disease, and lower rates of antimicrobial prophylaxis or corticosteroid use compared with both their baseline and those of conventionally treated patients. HCT leads to durable resolution of CGD symptoms and lowers the burden of the disease. Patients with active infection or inflammation are candidates for transplants; HCT should be considered before the development of comorbidities that could affect performance status. This trial was registered at www.clinicaltrials.gov as #NCT02082353.

BACKGROUND: In the United States, rare disease (RD) is defined as a condition that affects fewer than 200,000 individuals. Collectively, RD affects an estimated 30 million Americans. A significant portion of RD has an underlying genetic cause; however, this may go undiagnosed. To better serve these patients, the Mayo Clinic Program for Rare and Undiagnosed Diseases (PRaUD) was created under the auspices of the Center for Individualized Medicine (CIM) aiming to integrate genomics into subspecialty practice including targeted genetic testing, research, and education. METHODS: Patients were identified by subspecialty healthcare providers from 11 clinical divisions/departments. Targeted multi-gene panels or custom exome/genome-based panels were utilized. To support the goals of PRaUD, a new clinical service model, the Genetic Testing and Counseling (GTAC) unit, was established to improve access and increase efficiency for genetic test facilitation. The GTAC unit includes genetic counselors, genetic counseling assistants, genetic nurses, and a medical geneticist. Patients receive abbreviated point-of-care genetic counseling and testing through a partnership with subspecialty providers. RESULTS: Implementation of PRaUD began in 2018 and GTAC unit launched in 2020 to support program expansion. Currently, 29 RD clinical indications are included in 11 specialty divisions/departments with over 142 referring providers. To date, 1152 patients have been evaluated with an overall solved or likely solved rate of 17.5% and as high as 66.7% depending on the phenotype. Noteworthy, 42.7% of the solved or likely solved patients underwent changes in medical management and outcome based on genetic test results. CONCLUSION: Implementation of PRaUD and GTAC have enabled subspecialty practices advance expertise in RD where genetic counselors have not historically been embedded in practice. Democratizing access to genetic testing and counseling can broaden the reach of patients with RD and increase the diagnostic yield of such indications leading to better medical management as well as expanding research opportunities.

The patient is an otherwise healthy two-month-old boy who received the recommended vaccinations for his age group, which included the rotavirus pentavalent vaccine (RV5; RotaTeq) at his two-month well child visit. Three days later, he developed prolonged non-bloody diarrhea and was found to have persistently positive rotavirus antigen in his stool. Subsequent workup revealed mild defects in his functional T-cell immunocompetence. Genetic testing was obtained through the Invitae panel and was negative for hereditary forms of primary immunodeficiencies. The rotavirus antigen was found to have cleared from his stool around four months after receiving the RV5. Unfortunately, the source of the rotavirus infection was unable to be determined. The caregivers had misconceptions about the vaccine and the child's immune system function which led to refusal of any further vaccinations. Healthcare providers should strive to develop honest and respectful relationships with parents to have thoughtful dialogues regarding vaccine safety and efficacy.

The PAX1 gene plays an important role in the development of the parathyroid glands and the thymus. Mouse knockout models of PAX1, PAX3, and PAX9 have been found to have hypoplastic or absent parathyroid glands. To our knowledge, there are no reported cases of PAX1-associated hypoparathyroidism in humans. We present a case of hypoparathyroidism in a 23-month-old boy with a homozygous pathogenic variant in the PAX1 gene (PAX1 NM_006192.5 c.463_465del variant), predicted to cause an in-frame deletion of asparagine at position 155 (p.Asn155del) of the PAX1 protein. The hypoparathyroidism was unmasked after the patient developed significant hypocalcemia while receiving GoLYTELY (polyethylene glycol 3350, sodium sulfate anhydrous, sodium bicarbonate, sodium chloride, potassium chloride) for bowel cleanout. The patient had mild and asymptomatic hypocalcemia prior to hospitalization. The patient was noted to have inappropriately normal parathyroid hormone (PTH) level at the time of documented hypocalcemia thereby suggesting a diagnosis of hypoparathyroidism. Plain language summary: The first human case of hypoparathyroidism associated with a rare genetic disorder: a case report of PAX1 gene mutation The paired box (PAX) gene family is important for embryo development. One subfamily, PAX1, is necessary for development of the spinal column, thymus (important for the immune system development), and parathyroid (helps regulate the amount of calcium in the body). We present the case of a 23-month-old boy with known PAX1 gene mutation who came in with episodes of vomiting and poor growth. His presentation was thought to be most likely related to constipation. He was started on bowel cleanout medication and intravenous fluids. However, his calcium that had been mildly low subsequently dropped to very low levels. The level of parathyroid hormone (which helps regulate calcium levels) was inappropriately normal, meaning that his body was unable to make more, and was consistent with hypoparathyroidism. He was treated with calcium supplements and vitamin D and calcium levels normalized. He continues to be on calcium and vitamin D and calcium levels have remained stable. Doctors should keep this complication in mind when treating patients with PAX1 gene mutation.
RESUMO
Background: The past 2 years of the COVID-19 pandemic brought with it many unknowns for patients with immunodeficiency. Because of the concern for severe infection in those with immunocompromise, patients have been eager for effective prevention, vaccination, and treatment strategies. Preexposure prophylaxis provides another means of prevention in those with immunocompromise. A combination of tixagevimab and cilgavimab (Evusheld [AstraZeneca Cambridge, United Kingdom]) was granted emergency use authorization for preexposure prophylaxis at the end of 2021, but questions remained regarding how this would be tolerated and the side effects associated with its use. Objectives: Our aim was to evaluate the safety and tolerability of Evusheld in patients with CVID from our tri-site institution. Methods: We performed an institutional review board-approved, retrospective chart review of patients with common variable immunodeficiency (CVID) who received Evusheld before March 26, 2022. Results: Of the 45 patients with CVID who received Evusheld, 41 (91%) received the recommended full dose of 600 mg. The majority of patients (39 of 45 [87%]) tolerated Evusheld without adverse events. The adverse events reported included immediate injection site pain, fatigue and cough, an episode of shingles, and chest pain. Conclusions: This is an initial report on the safety and tolerability of Evusheld injections in patients with CVID. The majority of patients tolerated the injections without adverse events. For patients with reported chest pain, the results of a subsequent cardiac workup were negative. The efficacy of Evusheld could not be evaluated owing to the short median follow-up of this study (19 days).
RESUMO
Patient satisfaction (PS) surveying has become a commonly used measure of physician performance, but little is known about the impact on pediatricians. To investigate our hypothesis that PS surveys negatively impact pediatricians, we conducted a survey at an academic children's medical center. Of 155 eligible physicians, 115 responded (response rate 74%). Two-thirds (68%) did not find the PS score report useful and 88% did not feel that PS scores accurately reflect the physician's clinical ability. A third reported ordering tests, medications, or consultations due to pressure for higher PS scores. In addition, one-third agreed that PS surveys contribute to burnout and make it difficult to practice meaningful medicine. Overall, PS score reporting has a negative impact on pediatricians, especially those who are female, BIPOC (Black, Indigenous, and People of color), subspecialists, younger, and attended non-US medical schools. Further investigation into improved methods for providing feedback to pediatric physicians is warranted.

BACKGROUND: Shearer et al in 2014 articulated well-defined criteria for the diagnosis and classification of severe combined immunodeficiency (SCID) as part of the Primary Immune Deficiency Treatment Consortium's (PIDTC's) prospective and retrospective studies of SCID. OBJECTIVE: Because of the advent of newborn screening for SCID and expanded availability of genetic sequencing, revision of the PIDTC 2014 Criteria was needed. METHODS: We developed and tested updated PIDTC 2022 SCID Definitions by analyzing 379 patients proposed for prospective enrollment into Protocol 6901, focusing on the ability to distinguish patients with various SCID subtypes. RESULTS: According to PIDTC 2022 Definitions, 18 of 353 patients eligible per 2014 Criteria were considered not to have SCID, whereas 11 of 26 patients ineligible per 2014 Criteria were determined to have SCID. Of note, very low numbers of autologous T cells (<0.05 × 109/L) characterized typical SCID under the 2022 Definitions. Pathogenic variant(s) in SCID-associated genes was identified in 93% of patients, with 7 genes (IL2RG, RAG1, ADA, IL7R, DCLRE1C, JAK3, and RAG2) accounting for 89% of typical SCID. Three genotypes (RAG1, ADA, and RMRP) accounted for 57% of cases of leaky/atypical SCID; there were 13 other rare genotypes. Patients with leaky/atypical SCID were more likely to be diagnosed at more than age 1 year than those with typical SCID lacking maternal T cells: 20% versus 1% (P < .001). Although repeat testing proved important, an initial CD3 T-cell count of less than 0.05 × 109/L differentiated cases of typical SCID lacking maternal cells from leaky/atypical SCID: 97% versus 7% (P < .001). CONCLUSIONS: The PIDTC 2022 Definitions describe SCID and its subtypes more precisely than before, facilitating analyses of SCID characteristics and outcomes.

OBJECTIVE: To estimate the incidence of invasive pneumococcal disease (IPD) in the pre-13-valent pneumococcal conjugate vaccine (pre-PCV13; 7-valent pneumococcal conjugate vaccine era, 2002-2010) and post-PCV13 (2011-2018) time periods. PATIENTS AND METHODS: Using the Rochester Epidemiology Project, we conducted a population-based cohort study of all IPD cases in Olmsted County, Minnesota, from January 1, 2002, to December 31, 2018. RESULTS: Overall, 187 cases of IPD were identified. The incidence of IPD decreased significantly from 11.1 (95% CI, 9.1 to 13.2) to 5.6 (95% CI, 4.3 to 6.9) per 100,000 person-years when the pre- and post-PCV13 periods (2002-2010 vs 2011-2018) were compared (P<.001). Of the 187 patients with IPD, 112 (59.9%) had previously received at least 1 dose of pneumococcal vaccine. Among the IPD cases in the post-PCV13 period, there was an increase in non-PCV13 serotypes, mainly 11A (from 1.0% [1 of 105] to 6.2% [4 of 64]) and 33F (from 2.9% [3 of 105] to 15.6% [10 of 64]), while PCV13/non-7-valent pneumococcal conjugate vaccine serotypes declined from 38.1% (40 of 105) to 15.6% (10 of 64). At 30 days after an IPD diagnosis, the survival rate was 88.8% (95% CI, 84.4% to 93.4%). CONCLUSION: A marked decline in IPD incidence occurred during the post-PCV13 era. Because of the observed increase in non-PCV13 serotypes, coupled with multiple factors that impact the epidemiology of IPD, ongoing surveillance of patients with IPD, particularly due to non-PCV13 serotypes, is warranted.

BACKGROUND: Vaccine nonresponse during the coronavirus disease 2019 (COVID-19) pandemic has considerable individual and societal risks. OBJECTIVE: To investigate the clinical characteristics of patients with lack of seroconversion after vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). METHODS: Demographic and clinical data were collected from 805 patients who had validated antibody assays against the SARS-CoV-2 spike protein at least 14 days after completion of their COVID-19 vaccination. Clinical characteristics from patients with a negative (< 0.4 U/mL) antibody response were assessed and summarized. RESULTS: A total of 622 (77.3%) patients attained seroconversion as defined by a titer of greater than or equal to 0.4 U/mL, whereas 183 out of 805 (22.7%) patients exhibited no seroconversion after vaccination against SARS-CoV-2. Univariately, older age (P = .02) and male sex were associated with a lower likelihood of seroconversion (P = .003). Therapy with immunosuppressive drugs was noted in 93 (50.8%) of seronegative patients with most (n = 83/93, 89.2%) receiving ongoing immunosuppressive therapy at the time of vaccination. Among the 134 (73.2%) seronegative patients with immunodeficiency, 110 (82.1%) had primary immunodeficiency. Cancer (n = 128, 69.9%), B cell depletion therapy (n = 90/115, 78.3%), and immunosuppressant steroid use (n = 71/93 on immunosuppressants, 76.3%) were the other common characteristics among the vaccine nonresponders. More importantly, our study did not evaluate the actual efficacy of COVID-19 vaccination. CONCLUSION: Vaccine responses vary by age and sex, with men showing lower rates of seroconversion as compared with women. Primary immunodeficiency along with active malignancy and ongoing immunosuppression with steroids or B cell depletion therapy appeared to be the most common characteristics for those with a lack of vaccine seroconversion after COVID-19 vaccination.

PURPOSE: This is a functional characterization of a novel CYBA variant associated with normal DHR flow cytometry. Chronic granulomatous disease (CGD) is an inborn error of immunity characterized by recurrent bacterial and fungal infections and dysregulated inflammatory responses due to defective phagocytic cell function leading to the formation of granulomas. CGD patients have pathogenic variants in any of the five components of the phagocytic NADPH oxidase, which transfers electrons through the phagosomal membrane and produces superoxide upon bacterial uptake. Here, we report a pediatric female patient with a novel homozygous missense variant (c.293C > T, p.(Ser98Leu)) in CYBA, encoding the p22phox protein, associated with autosomal recessive CGD. METHODS AND RESULTS: The patient presented with severe recurrent pneumonia. Specific pathogens identified included Burkholderia and Serratia species suggesting neutrophil functional abnormalities; however, the dihydrorhodamine-1,2,3 (DHR) flow cytometric and cytochrome c reduction assays for neutrophil respiratory burst fell within the low side of the normal range. Western blot and flow cytometric analysis of individual NADPH oxidase components revealed reduced levels of p22phox and gp91phoxphox proteins. The pathological consequence of the p.Ser98Leu variant was further evaluated in heterologous expression systems, which confirmed reduced p22phox protein stability and oxidase activity. CONCLUSIONS: Although this patient did not exhibit all the classic features of CGD, such as granulomas and skin infections, she had recurrent pneumonias with oxidant-sensitive pathognomonic organisms, resulting in appropriate targeted CGD testing. This case emphasizes the need to contextually interpret laboratory data, especially using clinical findings to direct additional assessments including genetic analysis.

OBJECTIVE: To describe the clinical data from the first 108 patients seen in the Mayo Clinic post-COVID-19 care clinic (PCOCC). METHODS: After Institutional Review Board approval, we reviewed the charts of the first 108 patients seen between January 19, 2021, and April 29, 2021, in the PCOCC and abstracted from the electronic medical record into a standardized database to facilitate analysis. Patients were grouped into phenotypes by expert review. RESULTS: Most of the patients seen in our clinic were female (75%; 81/108), and the median age at presentation was 46 years (interquartile range, 37 to 55 years). All had post-acute sequelae of SARS-CoV-2 infection, with 6 clinical phenotypes being identified: fatigue predominant (n=69), dyspnea predominant (n=23), myalgia predominant (n=6), orthostasis predominant (n=6), chest pain predominant (n=3), and headache predominant (n=1). The fatigue-predominant phenotype was more common in women, and the dyspnea-predominant phenotype was more common in men. Interleukin 6 (IL-6) was elevated in 61% of patients (69% of women; P=.0046), which was more common than elevation in C-reactive protein and erythrocyte sedimentation rate, identified in 17% and 20% of cases, respectively. CONCLUSION: In our PCOCC, we observed several distinct clinical phenotypes. Fatigue predominance was the most common presentation and was associated with elevated IL-6 levels and female sex. Dyspnea predominance was more common in men and was not associated with elevated IL-6 levels. IL-6 levels were more likely than erythrocyte sedimentation rate and C-reactive protein to be elevated in patients with post-acute sequelae of SARS-CoV-2 infection.

Background: As the vaccination campaign in response to the coronavirus disease 2019 (COVID-19) pandemic continues, concerns with regard to adverse reactions to the vaccine remain. Although immediate hypersensitivity reactions have received much attention, delayed systemic urticarial reactions after vaccination can occur. Objective: To describe the clinical presentation, vaccine excipient skin testing results, and outcomes of subsequent COVID-19 vaccination in patients who experienced delayed systemic urticarial reactions after messenger RNA (mRNA) COVID-19 vaccination. Methods: This was a retrospective case series of 12 patients referred to the Mayo Clinics in Rochester, Minnesota, and Jacksonville, Florida, between January 19, 2021, and April 30, 2021, for evaluation of delayed systemic urticarial reactions after mRNA COVID-19 vaccination. Demographics, medical and allergic history, reaction details, vaccine excipient skin testing results (when performed), and the outcome after subsequent vaccination were collected for each patient. Results: The mean age of the patients was 52 years, all were white, and 9 (75%) were women. Half of the patients had a history of drug allergy, and one had a history of chronic spontaneous urticaria. Seven patients reacted to the Pfizer-BioNTech vaccine and five reacted to the Moderna vaccine. Seven patients developed symptoms between 8 and 24 hours after vaccination. Nine patients required antihistamines for treatment. The median time to symptom resolution was 4 days. Nine patients underwent allergist-directed COVID-19 vaccine excipient skin testing, all of which were negative. Ten patients chose to receive their next mRNA COVID-19 vaccine dose, and four patients experienced recurrent delayed urticaria. Conclusion: Delayed systemic urticarial reactions after mRNA COVID-19 vaccination were not life-threatening, could be treated with antihistamines, and were not predicted with vaccine excipient skin testing. They were not a contraindication to subsequent vaccination, although patients should be counseled with regard to the possibility of recurrence.

Background: There is growing concern about the rising incidence and prevalence of food allergy globally. We previously reported the incidence of food allergy in Olmsted County, Minnesota, between 2002 and 2011. We sought to update the incidence and temporal trends of food allergies in our region through 2018. Methods: By using the Rochester Epidemiology Project, all Olmsted County residents, with an incident diagnosis of food allergy between January 2, 2012, and December 31, 2018, were identified and their medical records were reviewed. These cases were combined with the previously collected incidence cases from January 2, 2002, and December 31, 2011, to understand longitudinal trends in food allergy incidence rates. Results: Over the 17-year study period, 1076 patients (58.0% male patients, 72.1% white) were diagnosed with an incident food allergy. The median (interquartile range) age at first diagnosis was 2.0 years (1.1-8.4 years). The overall annual incidence rate for all ages was 3.9 (95% confidence interval [CI], 3.6-4.1) per 10,000 person-years and was significantly higher in male than in female patients (4.4 [95% CI, 4.0-4.7] and 3.3 [95% CI, 3.0-3.6], respectively; p < 0.001). The most common food allergen was egg in infancy (57.7%), peanuts in ages 1-4 years (58.3%), tree nuts in ages 5-18 years (57.4%), and seafood in adults (≥19 years) (45.3%). Conclusion: The incidence of food allergy in Olmsted County steadily increased from 2002 to 2008, then remained relatively stable between the years 2008 and 2013, and again presented a rising trend over the next 5 years until 2018. This warrants further investigations into the effects of changes in guidelines for early introductions of allergenic foods and other factors that affect causality.

BACKGROUND: The mechanism of coronavirus disease 2019 (COVID-19) vaccine hypersensitivity reactions is unknown. COVID-19 vaccine excipient skin testing has been used in evaluation of these reactions, but its utility in predicting subsequent COVID-19 vaccine tolerance is also unknown. OBJECTIVE: To evaluate the utility of COVID-19 vaccine and vaccine excipient skin testing in both patients with an allergic reaction to their first messenger RNA COVID-19 vaccine dose and patients with a history of polyethylene glycol allergy who have not yet received a COVID-19 vaccine dose. METHODS: In this multicenter, retrospective review, COVID-19 vaccine and vaccine excipient skin testing was performed in patients referred to 1 of 3 large tertiary academic institutions. Patient medical records were reviewed after skin testing to determine subsequent COVID-19 vaccine tolerance. RESULTS: A total of 129 patients underwent skin testing, in whom 12 patients (9.3%) had positive results. There were 101 patients who received a COVID-19 vaccine after the skin testing, which was tolerated in 90 patients (89.1%) with no allergic symptoms, including 5 of 6 patients with positive skin testing results who received a COVID-19 vaccine after the skin testing. The remaining 11 patients experienced minor allergic symptoms after COVID-19 vaccination, none of whom required treatment beyond antihistamines. CONCLUSION: The low positivity rate of COVID-19 vaccine excipient skin testing and high rate of subsequent COVID-19 vaccine tolerance suggest a low utility of this method in evaluation of COVID-19 vaccine hypersensitivity reactions. Focus should shift to the use of existing vaccine allergy practice parameters, with consideration of graded dosing when necessary. On the basis of these results, strict avoidance of subsequent COVID-19 vaccination should be discouraged.
