Antihistamines for Postacute Sequelae of SARS-CoV-2 Infection

Abstract:

Postacute sequelae of SARS-CoV2 (PASC) infection is an emerging global health crisis, variably affecting millions worldwide. PASC has no established treatment. We describe 2 cases of PASC in response to opportune administration of over-the-counter antihistamines, with significant improvement in symptoms and ability to perform activities of daily living. Future studies are warranted to understand the potential role of histamine in the pathogenesis of PASC and explore the clinical benefits of antihistamines in the treatment of PASC.

Clinical patterns of somatic symptoms in patients suffering from post-acute long COVID: a systematic review

Abstract:

Background: Long COVID-19 may affect patients after hospital discharge.

Aims: This study aims to describe the burden of the long-term persistence of clinical symptoms in COVID-19 patients.

Methods: We conducted a systematic review by using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guideline. The PubMed and Google Scholar databases were searched for studies that included information on the prevalence of somatic clinical symptoms lasting at least 4 weeks after the onset of a PCR- or serology-confirmed diagnosis of COVID-19. The prevalence of persisting clinical symptoms was assessed and risk factors were described when investigated. Psychological symptoms and cognitive disorders were not evaluated in this study.

Results: Thirty-seven articles met the inclusion criteria. Eighteen studies involved in-patients only with a duration of follow-up of either less than 12 weeks, 12 weeks to 6 months, or more. In these studies, fatigue (16-64%), dyspnea (15-61%), cough (2-59%), arthralgia (8-55%), and thoracic pain (5-62%) were the most frequent persisting symptoms. In nineteen studies conducted in a majority of out-patients, the persistence of these symptoms was lower and 3% to 74% of patients reported prolonged smell and taste disorders. The main risk factors for persisting symptoms were being female, older, having comorbidities and severity at the acute phase of the disease.

Conclusion: COVID-19 patients should have access to dedicated multidisciplinary healthcare allowing a holistic approach. Effective outpatient care for patients with long-COVID-19 requires coordination across multiple sub-specialties, which can be proposed in specialized post-COVID units.

Physical and mental health 3 months after SARS-CoV-2 infection (long COVID) among adolescents in England (CLoCk): a national matched cohort study

Abstract:

Background: We describe post-COVID symptomatology in a non-hospitalised, national sample of adolescents aged 11-17 years with PCR-confirmed SARS-CoV-2 infection compared with matched adolescents with negative PCR status.

Methods: In this national cohort study, adolescents aged 11-17 years from the Public Health England database who tested positive for SARS-CoV-2 between January and March, 2021, were matched by month of test, age, sex, and geographical region to adolescents who tested negative. 3 months after testing, a subsample of adolescents were contacted to complete a detailed questionnaire, which collected data on demographics and their physical and mental health at the time of PCR testing (retrospectively) and at the time of completing the questionnaire (prospectively). We compared symptoms between the test-postive and test-negative groups, and used latent class analysis to assess whether and how physical symptoms at baseline and at 3 months clustered among participants. This study is registered with the ISRCTN registry (ISRCTN 34804192).

Findings: 23 048 adolescents who tested positive and 27 798 adolescents who tested negative between Jan 1, 2021, and March 31, 2021, were contacted, and 6804 adolescents (3065 who tested positive and 3739 who tested negative) completed the questionnaire (response rate 13·4%). At PCR testing, 1084 (35·4%) who tested positive and 309 (8·3%) who tested negative were symptomatic and 936 (30·5%) from the test-positive group and 231 (6·2%) from the test-negative group had three or more symptoms. 3 months after testing, 2038 (66·5%) who tested positive and 1993 (53·3%) who tested negative had any symptoms, and 928 (30·3%) from the test-positive group and 603 (16·2%) from the test-negative group had three or more symptoms. At 3 months after testing, the most common symptoms among the test-positive group were tiredness (1196 [39·0%]), headache (710 [23·2%]), and shortness of breath (717 [23·4%]), and among the test-negative group were tiredness (911 [24·4%]), headache (530 [14·2%]), and other (unspecified; 590 [15·8%]). Latent class analysis identified two classes, characterised by few or multiple symptoms. The estimated probability of being in the multiple symptom class was 29·6% (95% CI 27·4-31·7) for the test-positive group and 19·3% (17·7-21·0) for the test-negative group (risk ratio 1·53; 95% CI 1·35-1·70). The multiple symptoms class was more frequent among those with positive PCR results than negative results, in girls than boys, in adolescents aged 15-17 years than those aged 11-14 years, and in those with lower pretest physical and mental health.

Interpretation: Adolescents who tested positive for SARS-CoV-2 had similar symptoms to those who tested negative, but had a higher prevalence of single and, particularly, multiple symptoms at the time of PCR testing and 3 months later. Clinicians should consider multiple symptoms that affect functioning and recognise different clusters of symptoms. The multiple and varied symptoms show that a multicomponent intervention will be required, and that mental and physical health symptoms occur concurrently, reflecting their close relationship.

Long COVID symptoms in SARS-CoV-2-positive adolescents and matched controls (LongCOVIDKidsDK): a national, cross-sectional study

Abstract:

Background: Many adolescents have been affected by the COVID-19 pandemic either directly by being infected with the virus or indirectly by lockdowns and restrictions influencing normal living. We aimed to investigate health, including symptoms of long COVID, in adolescents (aged 15-18 years) who tested positive for SARS-CoV-2 compared with a control group.

Methods: LongCOVIDKidsDK was a national, cross-sectional study carried out in Denmark, which included SARS-CoV-2-positive adolescents and matched controls. All Danish adolescents aged 15-18 years with a positive SARS-CoV-2 test during the period Jan 1, 2020, to July 12, 2021, and a control group matched (1:4) by age and sex were sent a survey from July 20, 2021. Participants had until Sept 15, 2021, to respond. Symptoms associated with COVID-19, school attendance, and health-related quality of life were investigated using ancillary questions and validated questionnaires (Paediatric Quality of Life Inventory [PedsQL] and Children’s Somatic Symptoms Inventory-24 [CSSI-24]). Statistical analyses included descriptive statistics and logistic regression. This study is registered at ClinicalTrials.gov, NCT04786353.

Findings: 24 315 adolescents with a positive SARS-CoV-2 test (case group) and 97 257 matched controls were invited to participate. 3013 matched controls were excluded because of suspected SARS-CoV-2 infection. 6630 (27·3%) responded in the case group and 21 640 (22·3%) responded and were eligible to participate in the control group. Across both groups, median age was 17·6 years (IQR 16·4-18·5), 16 277 (57·6%) of 28 270 responders were female, and 11 993 (42·4%) were male. Participants in the case group had greater odds of having at least one long COVID symptom lasting at least 2 months compared with the control group (3159 [61·9%] vs 12 340 [57·0%], odds ratio 1·22 [95% CI 1·15-1·30]; p<0·0001). Participants in the case group reported significantly lower symptom scores (ie, less somatic distress) on the CSSI-24 than in the control group: mean 10·7 (SD 11·4, median 7·0 [IQR 2·0-15·0]) versus 11·9 (10·6, 9·0 [4·0-17·0]; p<0·0001). Participants in the case group had better quality of life scores on the PedsQL than in the control group: physical functioning mean score 88·7 (SD 13·9, median 93·8 [IQR 84·4-100·0]) versus 86·5 (14·3, 90·6 [81·3-96·9]; p<0·0001); emotional functioning 77·1 (20·3, 80·0 [65·0-95·0]) versus 71·7 (21·4, 75·0 [60·0-90·0]; p<0·0001); social functioning 93·1 (12·5, 100·0 [90·0-100·0]) versus 88·4 (16·2, 95·0 [80·0-100·0]; p<0·0001); and school functioning 66·9 (22·5, 65·0 [60·0-85·0]) versus 62·9 (22·1, 65·0 [50·0-80·0]; p<0·0001). More participants in the case group than in the control group reported 16 or more sick days (1205 [18·2%] vs 2518 [11·6%]; p<0·0001) and 16 or more days of school absence (695 [10·5%] vs 1777 [8·2%]; p<0·0001).

Interpretation: Participants with SARS-CoV-2-positive tests had more long-lasting symptoms and sick leave, whereas participants in the control group had more short-lasting symptoms and worse quality of life. Knowledge of long COVID in adolescents is important to guide clinical recognition and management of this condition.

Neurocognitive Profiles in Patients With Persisting Cognitive Symptoms Associated With COVID-19

Abstract:

Objective: A subset of individuals with coronavirus disease 2019 (COVID-19) appears to develop persisting cognitive and medical symptoms. Research in the acute stages of illness, generally utilizing cognitive screening measures or case reports, suggests presence of deficits in attention and executive function. This observational study investigated cognitive functioning among individuals with persistent cognitive complaints about 5.5 months after COVID-19 infection.

Methods: Patients with polymerase chain reaction confirmed COVID-19 and persistent cognitive complaints underwent comprehensive in-person neuropsychological evaluations. Patients with prior neurological disorders were excluded. When diagnosed, 40% required hospitalization, 15% were in an intensive care unit, 10% needed mechanical ventilation, and 10% experienced delirium.

Results: This sample was predominately women (90%), White non-Hispanic (70%), with average education of 15 years. Mild cognitive deficits were seen on tests involving attention and processing speed or executive function. Seventy percent of patients were diagnosed with a mood disorder prior to COVID-19 infection. At the time of testing, 35%-40% endorsed moderate to severe mood symptoms and 85% noted significant fatigue as measured by the Fatigue Severity Scale.

Conclusions: The pattern of cognitive deficits, although mild, is consistent with prior research at the acute stage of the illness. These findings suggest that psychological factors and other persisting symptoms (e.g., sleep, fatigue) may play a significant role in subjective cognitive complaints in patients with persisting complaints post COVID-19 who did not require intensive treatment. These patients would likely benefit from resources to manage persisting or new mood symptoms and compensatory strategies for the cognitive inefficiencies they experience.

Lessons from Myalgic Encephalomyelitis/Chronic Fatigue Syndrome for Long COVID: Postexertional Symptom Exacerbation is an Abnormal Response to Exercise/Activity

Prolonged symptoms after infection with the novel coronavirus 2019 (SARS-COV-2) are an emerging challenge to individual patients, society, and clinicians. In a previous post on the JOSPT Blog, we identified several lessons from research and clinical practice in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) that are important lessons for long COVID. The purpose of this post is to discuss the phenomenon of postexertional symptom exacerbation (PESE) and its clinical identification to recognize the potential onset of long COVID.

Data from a large international web-based patient survey indicate substantial symptom overlap between postacute SARS-COV-2 infection (long COVID) and ME/CFS at 6 months following the onset of first symptoms. Three quarters of respondents noted disabling fatigue and over half noted cognitive dysfunction.4 A unique finding of this survey was that 75% of respondents noted PESE, which is a worsening of symptoms after activity/exercise.4 PESE is foundational to the diagnosis of ME/CFS and it is common with long COVID.4,5 This observation suggests we can further extend lessons from ME/CFS to develop our understanding of long COVID.

The Female-Predominant Persistent Immune Dysregulation of the Post-COVID Syndrome

Abstract:

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.

Inappropriate sinus tachycardia in long-COVID and other updates on recent autonomic research

As the COVID-19 pandemic continues to affect hundreds of millions of people worldwide, autonomic complications are being recognized with increasing frequency in both the acute and chronic form of the illness, the latter now designated as post-acute sequelae of SARS-CoV-2 (PASC), colloquially termed long-COVID. Tachycardia is a common symptom of PASC, and some patients may be diagnosed with postural tachycardia syndrome (POTS) or inappropriate sinus tachycardia (IST). While post-COVID POTS has garnered more attention from the scientific and popular press, IST may be equally or more common and has been reported in survivors of the prior SARS coronavirus pandemic [1]. The etiology of IST is unknown; however, the proposed mechanisms overlap with those of POTS, including increased sympathetic and/or reduced cardiovagal activity.

In their recent publication [2], “Inappropriate sinus tachycardia in post-COVID-19 syndrome” Aranyo and colleagues identified 200 consecutive patients with PASC. IST was defined according to consensus criteria as symptomatic sinus rhythm rate ≥ 100 bpm at rest with a mean 24-h heart rate above 90 beats/min in the absence of any acute physiological demand or conditions known to produce sinus tachycardia. All patients underwent a 10-min active stand test to help rule out disorders of orthostatic intolerance, such as POTS and orthostatic hypotension. In addition, patients underwent an echocardiogram, 24-h Holter monitoring, a 6-min walk test (6MWT), and measurements of blood markers of inflammation and myocardial damage, including ferritin and interleukin-6. Heart rate variability (HRV) analysis was performed from the 24-h Holter data, focusing on standard time-domain parameters such as the RR interval, standard deviation of the inter-beat interval (SDNN), and the percentage of adjacent NN intervals that differed from each other by more than 50 ms (PNN50), as well as standard frequency-domain parameters including very low-frequency (VLF; 0.003–0.04 Hz), low-frequency (LF; 0.04–0.15 Hz), and high-frequency (HF; 0.15–0.40 Hz) bands. The HF band and PNN50 are regarded as indicators of the parasympathetic influence on heart rate, whereas the LF and VLF bands have more complex physiology that integrates both the sympathetic and parasympathetic components. Comparison groups included age- and gender-matched PCR-confirmed COVID patients without IST (fully recovered group, N = 19) and age- and gender-matched controls who had no history of SARS-COV-2 disease, as confirmed by negative serology (uninfected group, N = 17).

The authors identified 40 patients with IST from the cohort of 200 patients with PASC yielding an estimated prevalence of 20%. Eighty-five percent of the subjects were women and 83% had a history of mild COVID defined as the presence of symptoms without evidence of viral pneumonia or hypoxia. Most patients reported cardiopulmonary symptoms at the onset of their infection, including palpitations (90%), dyspnea (83%), and chest pain (78%); 53% reported dizziness and 48% anosmia. Compared to fully recovered patients, patients with IST were more likely to report palpitations (90% vs. 5%; p < 0.001), dyspnea (82% vs. 16%; p < 0.001), chest pain (78% vs. 21%; p < 0.001), headache (73% vs. 37%; p = 0.007), dizziness (53% vs. 5%; p = 0.002), diarrhea (53% vs. 16%; p = 0.003), and dermatological alterations (35% vs. 5%; p = 0.009) during the acute phase of SARS-CoV-2 infection. Patients with IST were also more likely to report environmental allergies compared to the fully recovered and uninfected groups (25% vs. 0%; p = 0.01), hinting at a potential mast cell component.

The 6MWT showed that patients with PASC with IST had a significantly reduced exercise capacity, with a 60% reduction in their estimated normal distance. Frequency analysis of heart rate variability revealed that patients with IST had a reduction in VLF, LF, and HF domains compared to controls, with more severe impairment in the parasympathetic-influenced domains. There was no difference in blood inflammatory markers between groups.

Limitations of this work include the small sample sizes of the control groups, as well as the lack of systematic pulmonary evaluations, measurement of markers of physical deconditioning, and systematic autonomic testing. Nonetheless, this study provides the first glimpse of how common IST may be in PASC and adds to the growing body of literature on autonomic dysfunction as a potential mechanism in PASC-related disability. With the Omicron variant currently surging across the globe, PASC-related autonomic complications will, unfortunately, be with us for some time, and clinicians should be familiar with their manifestations and potential treatment options.

Long COVID Patient Fact Sheet

‘Long COVID’ is the term that is often used to describe these persistent symptoms. You are considered to have ‘Long COVID’ when you are still having symptoms at least 4 weeks after the initial infection. Long COVID may also be referred to by other names such as post-COVID conditions, PASC (post-acute sequelae of COVID-19) or long-haul COVID.

Who Could Develop Long COVID?

Researchers around the world are trying to understand why some people develop Long COVID. People of all ages have been diagnosed with long COVID, including people with no underlying health conditions. Young and otherwise healthy people, and even those with mild infections, can be affected. More research is needed on the wide range of symptoms and why some people have more severe symptoms than others.

Mid and long-term neurological and neuropsychiatric manifestations of post-COVID-19 syndrome: A meta-analysis

Abstract

Importance: Neurological and neuropsychiatric symptoms that persist or develop three months after the onset of COVID-19 pose a significant threat to the global healthcare system. These symptoms are yet to be synthesized and quantified via meta-analysis.

Objective: To determine the prevalence of neurological and neuropsychiatric symptoms reported 12 weeks (3 months) or more after acute COVID-19 onset in adults.

Data sources: A systematic search of PubMed, EMBASE, Web of Science, Google Scholar and Scopus was conducted for studies published between January 1st, 2020 and August 1st, 2021. The systematic review was guided by Preferred Reporting Items for Systematic Review and Meta-Analyses.

Study selection: Studies were included if the length of follow-up satisfied the National Institute for Healthcare Excellence (NICE) definition of post-COVID-19 syndrome (symptoms that develop or persist ≥3 months after the onset of COVID-19). Additional criteria included the reporting of neurological or neuropsychiatric symptoms in individuals with COVID-19.

Data extraction and synthesis: Two authors independently extracted data on patient characteristics, hospital and/or ICU admission, acute-phase COVID-19 symptoms, length of follow-up, and neurological and neuropsychiatric symptoms.

Main outcome(s) and measure(s): The primary outcome was the prevalence of neurological and neuropsychiatric symptoms reported ≥3 months post onset of COVID-19. We also compared post-COVID-19 syndrome in hospitalised vs. non-hospitalised patients, with vs. without ICU admission during the acute phase of infection, and with mid-term (3 to 6 months) and long-term (>6 months) follow-up.

Results: Of 1458 articles, 19 studies, encompassing a total of 11,324 patients, were analysed. Overall prevalence for neurological post-COVID-19 symptoms were: fatigue (37%, 95% CI: 24%-50%), brain fog (32%, 9%-55%), memory issues (27%, 18%-36%), attention disorder (22%, 10%-34%), myalgia (18%, 4%-32%), anosmia (12%, 7%-17%), dysgeusia (11%, 4%-17%) and headache (10%, 1%-21%). Neuropsychiatric conditions included sleep disturbances (31%, 18%-43%), anxiety (23%, 13%-33%) and depression (12%, 7%-21%). Neuropsychiatric symptoms substantially increased in prevalence between mid- and long-term follow-up. Compared to non-hospitalised patients, patients hospitalised for acute COVID-19 had reduced frequency of anosmia, anxiety, depression, dysgeusia, fatigue, headache, myalgia, and sleep disturbance at three (or more) months post-infection. Conversely, hospital admission was associated with higher frequency of memory issues (OR: 1.9, 95% CI: 1.4-2.3). Cohorts with >20% of patients admitted to the ICU during acute COVID-19 experienced higher prevalence of fatigue, anxiety, depression, and sleep disturbances than cohorts with <20% of ICU admission.

Conclusions and relevance: Fatigue, cognitive dysfunction (brain fog, memory issues, attention disorder) and sleep disturbances appear to be key features of post-COVID-19 syndrome. Psychiatric manifestations (sleep disturbances, anxiety, and depression) are common and increase significantly in prevalence over time. Randomised controlled trials are necessary to develop intervention strategy to reduce disease burden.
