COVID-19 Post-acute Sequelae Among Adults: 12 Month Mortality Risk

Background: There are concerns regarding post-acute sequelae of COVID-19, but it is unclear whether COVID-19 poses a significant downstream mortality risk. The objective was to determine the relationship between COVID-19 infection and 12-month mortality after recovery from the initial episode of COVID-19 in adult patients.Methods: An analysis of electronic health records (EHR) was performed for a cohort of 13,638 patients, including COVID-19 positive and a comparison group of COVID-19 negative patients, who were followed for 12 months post COVID-19 episode at one health system. Both COVID-19 positive patients and COVID-19 negative patients were PCR validated. COVID-19 positive patients were classified as severe if they were hospitalized within the first 30 days of the date of their initial positive test. The 12-month risk of mortality was assessed in unadjusted Cox regressions and those adjusted for age, sex, race and comorbidities. Separate subgroup analyses were conducted for (a) patients aged 65 and older and (b) those <65 years.Results: Of the 13,638 patients included in this cohort, 178 had severe COVID-19, 246 had mild/moderate COVID-19, and 13,214 were COVID-19 negative. In the cohort, 2,686 died in the 12-month period. The 12-month adjusted all-cause mortality risk was significantly higher for patients with severe COVID-19 compared to both COVID-19 negative patients (HR 2.50; 95% CI 2.02, 3.09) and mild COVID-19 patients (HR 1.87; 95% CI 1.28, 2.74). The vast majority of deaths (79.5%) were for causes other than respiratory or cardiovascular conditions. Among patients aged <65 years, the pattern was similar but the mortality risk for patients with severe COVID-19 was increased compared to both COVID-19 negative patients (HR 3.33; 95% CI 2.35, 4.73) and mild COVID-19 patients (HR 2.83; 95% CI 1.59, 5.04). Patients aged 65 and older with severe COVID-19 were also at increased 12-month mortality risk compared to COVID-19 negative patients (HR 2.17; 95% CI 1.66, 2.84) but not mild COVID-19 patients (HR 1.41; 95% CI 0.84, 2.34).Discussion: Patients with a COVID-19 hospitalization were at significantly increased risk for future mortality. In a time when nearly all COVID-19 hospitalizations are preventable this study points to an important and under-investigated sequela of COVID-19 and the corresponding need for prevention.

A Descriptive Analysis of Immune Thrombotic Thrombocytopenic Purpura (iTTP) Patients with Fatal Outcomes in the U.S. Thrombotic Microangiopathy (USTMA) TTP Registry

Background: Immune thrombotic thrombocytopenic purpura (iTTP) is a rare, life-threatening thrombotic microangiopathy (TMA) occurring due to an acquired deficiency in ADAMTS13. Mortality due to iTTP is estimated at 10% with current standard treatment that consists of plasma exchange (PLEX) and corticosteroids. The United States TMA (USTMA) registry incorporates 15 large US referral centers across the nation, and includes patients diagnosed with iTTP between 1985 and 2019. We sought to perform a descriptive analysis on the patients with fatal outcomes attributable to acute iTTP episodes in the registry. Methods: We utilized the USTMA registry (n=771) and analyzed twenty-two baseline patient demographics, presenting symptoms, and laboratory findings. The study cohort included participants with iTTP diagnosis based on the presence of thrombocytopenia (platelet count <100 /µL), microangiopathic hemolyic anemia (hemoglobin less than the lower limit of normal with schistocytes on the peripheral blood smear), and either ADAMTS13 activity <10% or ADAMTS13 activity <20% with an anti-ADAMTS13 inhibitor or antibody. For participants diagnosed before the ADAMTS13 assay was developed (2006), the iTTP diagnosis was based on the clinical course and absence of alternative causes. iTTP exacerbation was defined as clinical disease recurrence within 30 days of PLEX discontinuation, and clinical relapse was defined as disease recurrence after 30 days of last PLEX, as per the international working group definitions 1. Results: A total of 33 patients (4.28%) in the USTMA cohort died during acute iTTP episodes. The patient demographics and initial presenting lab values are summarized in Table 1. Time of death (Figure 1): 22 patients (66.7%) died during the initial iTTP episode, and within 30 days of presentation. 3 patients (9.0%) died during disease exacerbation of the initial episode. 8 patients (24.2%) died due to disease relapse. Median time to death at initial presentation/exacerbation (n=25) = 8 days [IQR: 4-19] Median time to death due to relapse = 1.6 years [IQR: 1.1-5.7] Patient demographics and presenting features (Table 1): Median age = 51 years [IQR: 27.8-60] Sex = 54.5% female, 45.5% male Presence of neurologic symptoms on presentation: 22 (66.7%) Presence of any symptoms on presentation: 32 (97%) Conclusion: Patients with fatal outcomes due to acute iTTP episodes presented with variable symptoms and baseline characteristics. While the vast majority of deaths occurred during the initial acute episode, death also occurred during exacerbation of the initial episode or subsequent disease relapse. Vigilant laboratory and clinical monitoring both after achieving initial remission and during long-term follow-up are necessary, to allow detection of disease exacerbation and relapse, and potentially prevent iTTP-related deaths. 1.

Hypoalbuminemia linked to myocardial dysfunction in recent-onset nephrotic syndrome: a cross-sectional case control 3DSTE study

Background Although myocardial dysfunction in the context of longstanding steroid-resistant nephrotic syndrome (NS) has been the focus of many series, the detection of myocardial involvement in recent-onset NS has not taken sufficient attention. The primary outcome parameter of our study is the detection of myocardial dysfunction in the initial episode of NS (first 4 weeks after the onset), while the secondary outcome parameter is the determination of the best predictor of such dysfunction among systolic blood pressure, diastolic blood pressure, the duration of the initial episode of NS, and biochemical parameters such as serum albumin and cholesterol. Methods Forty NS patients during the initial episode of NS (first 4 weeks from the onset) were examined for anthropometric data as well as for serum albumin and cholesterol. Motion-mode echocardiography was used to determine Fractional shortening, while 3D echocardiography was applied to determine left ventricular (LV) ejection fraction (EF) and GLS (global longitudinal strain). Finally, we employed combined conventional and tissue doppler to determine LV E/e′ ratio (ratio of early transmitral inflow and average early diastolic basal septal and mitral annular velocities). Forty healthy, age- and sex-matched controls were enrolled to control advanced echocardiographic parameters. Results LV GLS was markedly reduced in cases compared to controls, denoting subtle systolic dysfunction, while, LV E/e′ ratio was significantly higher in cases denoting diastolic dysfunction in early NS. Hypoalbuminemia was found to be the best predictor of both LV GLS and LV E/e′ ratio. Conclusion Myocardial dysfunction should be considered in any NS patient even in recent-onset NS, the severity of hypoalbuminemia seems to be the best determinant of this dysfunction either by increasing endothelial dysfunction or through triggering inflammation. Further studies are needed on the mechanism by which hypoalbuminemia induces myocardial dysfunction in NS patients

Persistence of behavioral abnormalities following corticosteroid therapy in children with initial episode of idiopathic nephrotic syndrome: a prospective longitudinal observation

Introduction: Treatment of nephrotic syndrome with corticosteroid can cause several side- effects including behavioral abnormalities. The objectives of the study were to observe the proportion of non-relapsers having persistence of behavioral abnormalities after completion of treatment of initial episode and compare the abnormalities with relapsers, and to determine risk factors for persistence. Methods: Seventy-five children with a first episode of idiopathic nephrotic syndrome and 60 normal children were rated by parents for behavioral problems using the Child Behavior Checklist. The Parenting Stress Index was also evaluated. The children were rated before treatment and 12 and 36 weeks after. Results: Both relapsers and non-relapsers showed abnormalities in internalizing and externalizing domains at 12 weeks of steroid therapy. Non-relapsers had abnormal scores in the internalizing domain in 63.5 % and externalizing domain in 48.1% of cases at 36 weeks. Relapsers had abnormal scores in all the three behavior domains, but a significantly higher proportion of relapsers had abnormal scores regarding total behavior (65.2% vs 28.8%, p<0.01) and child domains (100% vs 57.7%, p<0.001) of Parenting Stress Index in comparison to non-relapsers at 36 weeks. Occurrence of relapse increased the risk (odds ratio 5.76, 95% CI 1.35-10.76, p< 0.001) for persistence of abnormal total behavior at 36 weeks follow-up. Conclusion: Persistence of abnormalities was observed not only in relapsers but also in non-relapsers. Relapse was found to be a significant risk factor for persistence of abnormal behaviors in these patients.

First-Episode Patients Report Cognitive Difficulties in Executive Functioning 1 Year After Initial Episode of Major Depressive Disorder

Objective: Major Depressive Disorder (MDD) is associated with cognitive impairment in general, and Executive Functioning (EF) in particular, even in remitted phase of the disorder, suggesting residual cognitive symptoms. The aim of the present study was to investigate self-reported EF 1 year after the first episode of MDD and to explore this in relation to depressive mood symptoms, remission and relapse.Method: The study included data from 24 patients and 23 healthy control subjects 1 year after the patients' initial first episode of MDD. All participants completed the Behavior Rating Inventory of Executive Functioning-Adult version (BRIEF-A), a standardized self-report measure of perceived EF in everyday life, measuring nine different EF. Total index scores for metacognitive functions, behavior/emotional regulation functions and a global EF score is also calculated.Results: The patient group in total, independent of symptom status, reported significantly lower EF in all indexes compared to the healthy controls 1 year after the initial episode. However, higher depressive mood symptom load correlated with self-reported difficulties in metacognitive functions and poor global EF scores. Regulatory control of behavior and emotional responses did not show such strong association with mood symptoms, but low self-report scores on this measure was associated with relapse during the first year after the initial episode.Conclusion: First-episode patients report significant lower executive functioning in everyday life compared to individually matched healthy controls, 1 year after onset, independent of symptom load. Residual cognitive symptoms seem to be evident and associated with risk of relapse and should be targeted in treatment and prevention of recurrence in MDD.

Kawasaki disease recurrence in the COVID-19 era: a systematic review of the literature

Kawasaki disease (KD) is a vasculitis of unknown origin of small and medium caliber blood vessels, especially involving coronary arteries and is the leading cause of acquired heart disease in childhood in developed countries. Although rarely, it can recur: most recurrences occur within 2 years of the initial episode. No data are available on incidence of recurrent KD in Europe and multiple recurrences are rarely seen. We reviewed the medical literature on Kawasaki disease recurrence and reported a new case of Kawasaki disease recurrence in a child with SARS-CoV-2 infection. We believe that in our case SARS Cov2 acted as a trigger capable to determine, in a genetically susceptible individual, a second recurrence of the disease. In the Covid-19 era we affirm the importance for Kawasaki disease to be tested for SARS Cov2 infection.

Successful use of early, repeat fecal microbiota transplantation for initial treatment of severe, refractory Clostridioides difficile colitis

Disclaimer In an effort to expedite the publication of articles related to the COVID-19 pandemic, AJHP is posting these manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. Purpose There is a paucity of literature surrounding the use of early fecal microbiota transplantation (FMT) for patients presenting with an initial episode of severe, refractory Clostridioides difficile infection (CDI). Information on optimal antibiotic dosing and therapy duration surrounding FMT during an acute, initial episode of CDI is also limited. Described here is a case of successful treatment of CDI after 4 FMTs during an acute, initial episode of severe, refractory Clostridioides difficile colitis. Summary A 69-year-old community-dwelling, Caucasian male presented after 48 hours of vomiting and diarrhea. A stool sample tested positive via stool sample by both polymerase chain reaction and enzme-linked immunosorbent assays for Clostridioides difficile. The patient was treated with several days of oral and rectal vancomycin therapy in addition to intravenous metronidazole, but those treatments failed. His clinical and nutrition status deteriorated over the course of several days until salvage therapy was ordered, with administration of 1 inpatient nasogastric FMT and 1 inpatient colonoscopic FMT followed by outpatient colonoscopic FMTs on 2 consecutive days within 2 weeks of hospital discharge. Conclusion This case suggests a role for early, repeat FMT during an initial presentation of a severe Clostridioides difficile colitis episode refractory to pharmacologic antimicrobial therapy. It also adds to emerging literature regarding the timing of antibiotic cessation surrounding FMT.

#37: Clinical Characterization of the Cases Relating to the Outbreak of Clostridioides difficile, in a Third-level Hospital in Mexico City: Diagnosis, Treatment, and Relay

Background Clostridioides difficile is an important cause of healthcare-associated infections. The epidemiology of C. difficile infection (CDI) in children has changed over the past few decades. There is now a higher incidence in hospitalized children, and there has been an emergence of community-onset infection. Neonates and young infants have high rates of colonization but rarely have symptoms. The well-known risk factor for CDI in children age 2 years or older is antibiotic use. Inflammatory bowel disease and cancer are associated with increased incidence and severity of CDI. Vancomycin or fidaxomicin is recommended for an initial episode of CDI. In environments where access to Vancomycin or Fidaxomycin is limited, it is suggested to use metronidazole for an initial episode of nonsevere CDI only. Methods A series of cases were carried out, in a study period from March to May 2018, total cases 8; the age group, sex, basic diagnosis, clinical findings, diagnostic method, and outcome in hospitalized patients in the Pediatric division of the “CMN 20 de Noviembre, ISSSTE” were described, where there is a total of 377 Sensitive beds, and 53 beds in the pediatric area of which 30 are not sensitive. Results We analyzed 8 cases of diarrhea with identification of C. difficile, in a period of 3 months, where there was a total of 148 admissions to the division of Pediatrics (100%) and presented a prevalence of 0.05% of the total income. Of those 8 cases reported, 37.5% were women and 62.5% men; The age fluctuated between 6 months and 18 years. All children had associated comorbidities. The frequency and type of comorbidities were Cancer 87.5% (Leukemias and Solid Tumors) and Neurological 12.5% ​​(Arterial Malformation and Neurological Sequelae). The main symptom that occurred was mucous diarrhea in 100% of patients, abdominal pain in 25% and evacuation with blood in 12.5% ​​of cases. All had a history of prior treatment with 100% broad-spectrum antibiotics, in a period of less than one month. All were treated with metronidazole (100%) and all presented clinical improvement, without complications; Similarly, all were diagnosed by PCR for toxin B (100%). The attributable risk of presenting Clostridioides disease in patients with Leukemia is 0.11. Conclusions Patients with Leukemia were the most affected during the C. difficile outbreak, of which 11 out of 100 of these patients are at risk of presenting C. difficile disease. The most important thing in these cases is prevention. Therefore, specific prevention measures were implemented to reduce the possibility of future outbreaks, such as handwashing with chlorexidine, contact isolation, handwashing every time there is contact with the patient, use of gloves when performing procedures, insulation of bedding in plastic bags and training of health personnel.
