Post-COVID-19 Symptoms in Adults with Asthma—Systematic Review

Abstract:

Background: Research on the longer-term sequelae of COVID-19 in patients with asthma is limited. Objective: To assess the frequency and severity of long-term symptoms of COVID-19 in the population of asthma patients.
Methods: A systematic review of the published literature was conducted in accordance with the recommendations of the PRISMA statement. EMBASE, MEDLINE/PubMed, Web of Science, CINAHL, and Scopus Scholar were searched for terms related to asthma and post or long COVID-19, and for systematic reviews related to specific questions within our review, up to June 2022.
Results: Data from 9 references publications included in the review were extracted. A total of 1466 adult asthmatic patients with COVID-19 infection were described in all the publications mentioned above. Of the long-term symptoms reported after COVID-19, patients indicated: lower respiratory symptoms, fatigue, cognitive symptoms, psychological problems, and other such as skin rashes, gastrointestinal disorders, tachycardia, palpitations, ocular disorders, ageusia/hypogeusia, anosmia/hyposmia, and poor sleep quality. These symptoms in similar intensity were observed in the comparison groups without a diagnosis of asthma.
Conclusions: The published data neither confirm nor deny that long-term COVID-19 symptoms in patients with asthma diagnosis are different in strength and frequency from patients without asthma diagnosis. To indicate associations between asthma and COVID-19 infection and severity, as well as the frequency of long-term symptoms of COVID-19, more longitudinal research is needed in chronic asthma patients with different phenotypes, intensity of treatment, and degree of asthma control.

Pre-existing allergic diseases as risk factors for long-term Long-COVID symptoms: a systematic review of prospective cohort studies

Abstract:

Background: The role of allergy as risk factor for Long-COVID (LC) is unclear. We aimed to systematically review and appraise the epidemiological evidence on allergic diseases as risk factors for LC (PROSPERO: CRD42023391245).
Methods: We examined literature for prospective cohort studies with a follow-up duration of 12 months for LC symptoms, published within the timeframe from January 2020 and January 2023 that recruited individuals with confirmed SARS-CoV-2 infection and information on pre-existing allergic diseases. Risk of bias and certainty of evidence were assessed (GRADE). Random effects meta-analyses were used to pool unadjusted ORs within homogeneous data subsets.
Results: We identified 13 studies (participants range = 39 – 1,950), all of which were associated with high risk of bias. Four of these studies did not provide data to calculate ORs. Significant associations were observed between increased LC incidences and pre-existing asthma measured in hospital-based populations ( n = 6) and pre-existing rhinitis ( n = 3) ( OR = 1.94; 95% CI [1.08, 3.50]; OR = 1.96; 95% CI [1.61, 2.39]), respectively. However, the level of certainty regarding these exposure outcome associations was very low.
Conclusion: Findings show that allergies may increase the risk of LC, although the reliability of this evidence is tenuous.

An investigation of symptoms predating CFS onset

Abstract:

The Fukuda et al. (1994) criteria for chronic fatigue syndrome (CFS) specifies that a symptom can only be included within a diagnosis if it is experienced concurrently or following the onset of fatigue. In order to investigate this issue, participants provided information on persisting symptoms (lasting greater than six months) and whether those symptoms occurred prior to, concurrently, or following the onset of their fatigue.

More symptoms were experienced after the fatigue onset than prior to the fatigue onset; however, a considerable number of participants reported experiencing persisting symptoms prior to the onset of CFS. Particularly, rates of hay fever and asthma were higher prior to the illness. Investigating symptoms prior to the onset of the illness might provide investigators with ways to better understand the etiology of this illness.

Chronic fatigue syndrome in psychiatric patients: lifetime and premorbid personal history of physical health

Abstract:

OBJECTIVE: This preliminary report compares a group of chronic fatigue syndrome (CFS) patients and controls on several variables of potential significance in the etiology of CFS.

METHOD: The lifetime prevalence of reported physical disorders was compared among 46 CFS psychiatric patients, 92 relatively physically healthy psychiatric patients (C-I), and 46 psychiatric patients selected without regard to physical health (C-II). All patients were matched on age, sex, and psychiatric diagnosis and were drawn from the same psychiatric practice. The same groups were compared on a 7-point scale of lifetime physical health by three raters independently evaluating physical health narratives of the CFS patients up to the time of onset of CFS and that of the controls up to the corresponding age.

RESULTS: The CFS patients had a significantly higher reported lifetime prevalence of irritable bowel syndrome (IBS), infectious mononucleosis-like syndromes (IM), infectious mononucleosis-like syndromes two or more times (IM x 2), and herpes (other than genital or perioral herpes) than one or both control groups. The CFS group also had a higher incidence of allergic rhinitis or asthma, IBS, IM, and IM x 2 than the combined controls. On the independent ratings, the CFS patients had significantly more impaired physical health up to the time of onset of the CFS than C-I at a comparable age.

CONCLUSIONS: The findings suggest that a general health factor may be involved in the pathogenesis of some cases of CFS.
