Persisting olfactory dysfunction in post-COVID-19 is associated with gustatory impairment: Results from chemosensitive testing eight months after the acute infection

Abstract:

Olfactory and gustatory disorders are prominent symptoms of acute COVID-19. Although both senses recover in many patients within weeks to months, persistency has been described in up to 60%. However up to now most reports on the course of chemosensitive disorders after COVID-19 are not based on psychophysical testing but only on subjective patients’ ratings. In this study we assessed both olfaction and gustation using psychophysical tests eight months after COVID-19. Validated psychophysical testing revealed hyposmia in 18% and hypogeusia in even 32% of 303 included patients. This shows that olfactory and especially gustatory disorders have to be seen as important chronic symptoms post-COVID-19. The high prevalence of gustatory dysfunction indicates that gustatory function does not recover or might even deteriorate in the months following the acute infection.

Representation of long COVID syndrome in the awareness of the population is revealed by Google Trends analysis

Abstract:

In some COVID-19 patients, symptoms persist for several weeks and sometimes, after the acute disease phase, these patients develop new symptoms, which then represents a transition into the so-called long COVID. The exact demarcation of the terms and generally applicable definitions are still discussed, but the phenomenon is most commonly referred to as long COVID.

In this study, Google Trends data have been used to track levels of public awareness for long COVID and some important symptoms during the course of the COVID-19 pandemic. The results of this analysis clearly demonstrate the public interest in the new topic of long COVID, as documented by a corresponding search volume. This is related to the disease COVID-19, which is being spread by the corona pandemic. Relevant symptoms for COVID-19 or long COVID, for example ageusia and anosmia, only started to receive more public attention during the pandemic. Therefore, Google Trends is a useful tool to demonstrate the population’s awareness of certain infodemiological topics like long COVID.

“Like before, but not exactly”: the Qualy-REACT qualitative inquiry into the lived experience of long COVID

Abstract:

Background: Post-acute sequelae of SARS-CoV-2 infection (PASC) affect millions of individuals worldwide. Rehabilitation interventions could support individuals during the recovery phase of COVID-19, but a comprehensive understanding of this new disease and its associated needs is crucial. This qualitative study investigated the experience of individuals who had been hospitalized for COVID-19, focusing on those needs and difficulties they perceived as most urgent.

Methods: This naturalistic qualitative study was part of a single-center mix-method cross-sectional study (REACT) conducted in Italy during the first peak of the SARS-CoV-2 pandemic. The qualitative data collection took place through a telephone interview conducted 3 months after hospital discharge. The experience of individuals discharged after hospitalization for COVID-19 was investigated through the main research question – “Tell me, how has it been going since you were discharged?”. Two secondary questions investigated symptoms, activities, and participation. Data were recorded and transcribed verbatim within 48 h. An empirical phenomenological approach was used by the researchers, who independently analyzed the data and, through consensus, developed an interpretative model to answer the research question. Translation occurred after data was analyzed.

Results: During the first peak of the COVID-19 pandemic, 784 individuals with COVID-19 were discharged from the hospitals of the Local Health Authority of the Province of Reggio Emilia (Italy); 446 were excluded due to the presence of acute or chronic conditions causing disability other than COVID-19 (n. 339), inability to participate in the study procedures (n. 56), insufficient medical documentation to allow for screening (n. 21), discharge to residential facilities (n. 25), and pregnancy (n. 5). Overall, 150 individuals consented to participate in the REACT study, and 56 individuals (60.7% male, average age 62.8 years ±11.8) were interviewed in June-July 2020, up to data saturation. Persistent symptoms, feelings of isolation, fear and stigma, emotional distress, a fatalistic attitude, and return to (adapted) life course were the key themes that characterized the participants’ experience after hospital discharge.

Conclusions: The experience as narrated by the participants in this study confirms the persistence of symptoms described in PASC and highlights the sense of isolation and psychological distress. These phenomena may trigger a vicious circle, but the participants also reported adaptation processes that allowed them to gradually return to their life course. Whether all individuals are able to rapidly activate these mechanisms and whether rehabilitation can help to break this vicious circle by improving residual symptoms remain to be seen.

Detection of Male Hypogonadism in Patients with Post COVID-19 Condition

Abstract:

The pathogenesis and prognosis of post COVID-19 condition have remained unclear. We set up an outpatient clinic specializing in long COVID in February 2021 and we have been investigating post COVID-19 condition. Based on the results of our earlier study showing that “general fatigue” mimicking myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is the most common symptom in long COVID patients, a retrospective analysis was performed for 39 male patients in whom serum free testosterone (FT) levels were measured out of 61 male patients who visited our clinic.

We analyzed the medical records of the patients’ backgrounds, symptoms and laboratory results. Among the 39 patients, 19 patients (48.7%) met the criteria for late-onset hypogonadism (LOH; FT < 8.5 pg/mL: LOH group) and 14 patients were under 50 years of age. A weak negative correlation was found between age and serum FT level (r = -0.301, p = 0.0624).

Symptoms including general fatigue, anxiety, cough and hair loss were more frequent in the LOH group than in the non-LOH group (FT ≥ 8.5 pg/mL). Among various laboratory parameters, blood hemoglobin level was slightly, but significantly, lower in the LOH group. Serum level of FT was positively correlated with the levels of blood hemoglobin and serum total protein and albumin in the total population, whereas these interrelationships were blurred in the LOH group.

Collectively, the results indicate that the incidence of LOH is relatively high in male patients, even young male patients, with post COVID-19 and that serum FT measurement is useful for revealing occult LOH status in patients with long COVID.

Patient-Reported Symptoms and Sequelae 12 Months After COVID-19 in Hospitalized Adults: A Multicenter Long-Term Follow-Up Study

Abstract:

Objective: Our knowledge on the long-term consequences of COVID-19 is still scarce despite the clinical relevance of persisting syndrome. The aim of this study was to analyze patient-reported outcomes, including assessment by specific questionnaires of health impairment and symptoms.

Methods: This is a prospective, observational and multicenter cohort study coordinated by Fondazione IRCSS Ca’ Granda Ospedale Maggiore Policlinico di Milano and Istituto di Ricerche Farmacologiche Mario Negri IRCCS including eight hospitals located in North and Central Italy. A telephone interview to assess rehospitalization, access to health care resources, general health status subjective evaluation, and symptoms was performed at 12 months after the discharge in patients admitted to hospital because of COVID-19 from February 2020 to the end of May 2020.

Results: Among the 776 patients discharged alive, 44 (5.7%) died, 456 subjects (58.8%) completed the questionnaire and 276 (35.6%) were not reachable or refused to join the telephone interview. The mean age of the study population was 59.4 years (SD 14.1), 69.8% of individuals needed oxygen support during hospitalization and 10.4% were admitted to ICU. Overall, 91.7% of participants reported at least one symptom/sequela at 12 months. Exertional dyspnea (71.7%), fatigue (54.6%), and gastrointestinal symptoms (32.8%) were the most reported ones. Health issues after discharge including hospitalization or access to emergency room were described by 19.4% of subjects. Female and presence of comorbidities were independent predictors of health impairment and presence of ≥2 symptoms/sequelae after 12 months from hospitalization for COVID-19.

Conclusions: Patient-reported symptoms and sequelae, principally dyspnea and fatigue, are found in most individuals even 12 months from COVID-19 hospitalization. Long-term follow-up based on patient-centered outcome can contribute to plan tailored interventions.

Persistent Brain Fog After Mild COVID Infection Tied to CSF Markers

Abstract:

As cases of coronavirus disease 2019 (COVID-19) mount worldwide, attention is needed on potential long-term neurologic impacts for the majority of patients who experience mild to moderate illness managed as outpatients. To date, there has not been discussion of persistent neurocognitive deficits in patients with milder COVID-19. We present two cases of non-hospitalized patients recovering from COVID-19 with persistent neurocognitive symptoms. Commonly used cognitive screens were normal, while more detailed testing revealed working memory and executive functioning deficits.

An observational cohort study of individuals recovering from COVID-19 (14 or more days following symptom onset) identified that among the first 100 individuals enrolled, 14 were non-hospitalized patients reporting persistent cognitive issues. These 14 participants had a median age of 39 years (interquartile range: 35-56), and cognitive symptoms were present for at least a median of 98 days (interquartile range: 71-120 following acute COVID-19 symptoms); no participants with follow-up evaluation reported symptom resolution. We discuss potential mechanisms to be explored in future studies, including direct viral effects, indirect consequences of immune activation, and immune dysregulation causing auto-antibody production.

Post COVID fatigue: Can we really ignore it?

Abstract:

Long-COVID, also referred to as post-acute COVID-19, chronic COVID-19, post-COVID syndrome, or post-acute sequelae of SARS-CoV-2 infection (PASC), generally refers to symptoms that develop during or after acute COVID-19 illness, continue for ≥12 weeks, and are not explained by an alternative diagnosis. It is not yet known whether “long-COVID” represents a new syndrome unique to COVID-19 or overlaps with recovery from similar illnesses. It’s difficult for physicians to predict when symptoms will improve as it varies differently in different people. Patient’s recovery depends on various factors including age, associated comorbidities, severity of COVID-19 infection. Some symptoms, like fatigue, might continue even while others improve or go away. This review addresses the pathogenesis, presentation of post covid fatigue, its severity and its management.

Sulodexide: A Benefit for Cardiovascular Sequelae of Long COVID Patients?

Dear Editor,

The elaborate and precise review of Harry N. Magnani didactically demonstrates the complex pathophysiological aspects of coronavirus disease 2019 (COVID-19) emphasizing the roles of vascular endothelial dysfunction and coagulation cascade as key features of disease progression.  Moreover, this article brings up that glycosaminoglycane (GAG) antithrombotics likely interfere with inflammatory and coagulation activity in an effective fashion.  Thereafter this postulate has become advocated as the application of sulodexide (Vessel Due F; ALFASIGMA, Italy) (SDX), an unexpensive and orally administrable GAG antithrombotic drug reduced the necessity for both hospital admission and oxygen supplementation in the early phase of SARS-Cov-2 infection under a randomized placebo-controlled out-patient trial.  Interestingly, these patients also showed lower serum levels of C-reactive protein (CRP) and D-dimer as markers of inflammation and prothrombotic state. Of note, instead of regularly recommended and prescribed 250 RLU twice-daily dose, the clinical trial applied the higher, 500 RLU twice-daily dosing regimen in which an antithrombotic effect was safely achieved in a clinical setting.

Sex-Related Differences in Long-COVID-19 Syndrome

Abstract:

Background: Sex differences have been demonstrated in the acute phase of COVID-19. Women (F) were found to be less prone to develop a severe disease than men (M), but few studies have assessed sex-differences in Long-COVID-19 syndrome.

Methods: The aim of this prospective/retrospective study was to characterize the long-term consequences of this infection based on sex. For this purpose, we enrolled 223 patients (89 F and 134 M) who were infected by SARS-CoV-2. In the acute phase of the illness, F reported the following symptoms more frequently than M: weakness, dysgeusia, anosmia, thoracic pain, palpitations, diarrhea, and myalgia-all without significant differences in breathlessness, cough, and sleep disturbance.

Results: After a mean follow-up time of 5 months after the acute phase, F were significantly more likely than M to report dyspnea, weakness, thoracic pain, palpitations, and sleep disturbance but not myalgia and cough. At the multivariate logistic regression, women were statistically significantly likely to experience persistent symptoms such as dyspnea, fatigue, chest pain, and palpitations. On the contrary, myalgia, cough, and sleep disturbance were not influenced by sex.

Conclusion: We demonstrated that F were more symptomatic than M not only in the acute phase but also at follow-up. Sex was found to be an important determinant of Long-COVID-19 syndrome because it is a significant predictor of persistent symptoms in F, such as dyspnea, fatigue, chest pain, and palpitations. Our results suggest the need for long-term follow-up of these patients from a sex perspective to implement early preventive and personalized therapeutic strategies.

Efficacy of Adaptogens in Patients with Long COVID-19: A Randomized, Quadruple-Blind, Placebo-Controlled Trial

Abstract:

Currently, no effective treatment of comorbid complications or COVID-19 long-haulers during convalescence is known. This randomized, quadruple-blind, placebo-controlled trial aimed to assess the efficacy of adaptogens on the recovery of patients with Long COVID symptoms. One hundred patients with confirmed positive SARS-CoV-2 test, discharged from COVID Hotel isolation, Intensive Care Unit (ICU), or Online Clinics, and who experienced at least three of nine Long COVID symptoms (fatigue, headache, respiratory insufficiency, cognitive performance, mood disorders, loss of smell, taste, and hair, sweatiness, cough, pain in joints, muscles, and chest) in the 30 days before randomization were included in the study of the efficacy of Chisan®/ADAPT-232 (a fixed combination of adaptogens Rhodiola, Eleutherococcus, and Schisandra) supplementation for two weeks.

Chisan® decreased the duration of fatigue and pain for one and two days, respectively, in 50% of patients. The number of patients with lack of fatigue and pain symptoms was significantly less in the Chisan® treatment group than in the placebo group on Days 9 (39% vs. 57%, pain relief, p = 0.0019) and 11 (28% vs. 43%, relief of fatigue, * p = 0.0157). Significant relief of severity of all Long COVID symptoms over the time of treatment and the follow-up period was observed in both groups of patients, notably decreasing the level of anxiety and depression from mild and moderate to normal, as well as increasing cognitive performance in patients in the d2 test for attention and increasing their physical activity and workout (daily walk time).

However, the significant difference between placebo and Chisan® treatment was observed only with a workout (daily walk time) and relieving respiratory insufficiency (cough). A clinical assessment of blood markers of the inflammatory response (C-reactive protein) and blood coagulation (D-dimer) did not reveal any significant difference over time between treatment groups except significantly lower IL-6 in the Chisan® treatment group. Furthermore, a significant difference between the placebo and Chisan® treatment was observed for creatinine: Chisan® significantly decreased blood creatinine compared to the placebo, suggesting prevention of renal failure progression in Long COVID. In this study, we, for the first time, demonstrate that adaptogens can increase physical performance in Long COVID and reduce the duration of fatigue and chronic pain. It also suggests that Chisan®/ADAPT-232 might be useful for preventing the progression of renal failure associated with increasing creatinine.
