A systematic review of dermatologic manifestations among adult patients with COVID-19 diagnosis

Cutaneous manifestations of COVID-19 patients in a Hospital in São Paulo, Brazil, and global literature review

BACKGROUND

Since the beginning of the COVID-19 pandemic, a myriad of cutaneous manifestations have been described in association with this viral infection. However, in Latin America, this kind of data is still scarce.

OBJECTIVE

In this sense, the goal of this study was to describe the dermatological findings observed during SARS-CoV-2 infection, in a Brazilian Hospital.

METHODS

This is a cross-sectional, retrospective and descriptive study of 50 cases of new-onset dermatologic symptoms in patients with COVID-19, treated at Hospital Sírio-Libanês, from February to June 2020.

RESULTS

The patients (n = 50) were classified into 6 groups, according to the elementary lesions and the statistical analysis was performed. The most common cutaneous lesions were maculopapular eruptions (44%), necrosis, purpura, and livedo (32%), urticarial lesions (12%), pseudochilblains (4%) and papular-vesicular eruption (4%). In 46% of the patients the cutaneous lesions occurred in association with other symptoms, such as pruritus (38%), pain and burning sensation (8%). Lower limbs were affected in 44% of the cases, followed by the trunk (38%), upper limbs (24%) and face (14%). Cutaneous lesions were mostly found after other COVID-19 systemic symptoms, with a mean period between the viral syndrome and cutaneous signs of 5 days (SD = 6.1 days).

STUDY LIMITATIONS

It is a small sample, in a single-center study, with patients exclusively from a private Hospital.

CONCLUSIONS

Patients in Brazil have the same proportion of lesions as revealed in other studies in Europa. The compiled data is essential for a better understanding of cutaneous manifestations deemed secondary to COVID.

Evaluation of the prevalence of new-onset musculoskeletal symptoms in patients hospitalized for severe SARS-CoV-2 infection during the first two COVID waves in France: A descriptive analysis of the clinical data warehouse of 39 hospitals in France

OBJECTIVE

To determine the prevalence of musculoskeletal (MSK) symptoms appearing after a SARS-CoV-2 infection.

METHODS

This was an observational cohort based on data available at the Assistance publique-Hôpitaux de Paris (AP-HP) Clinical Data Warehouse (which includes data of more than 11 million patients treated in the 39 hospitals from AP-HP). The data collected included both ICD-10 codes in discharge summaries, and recurring wording expressions search on medical electronic documents. To be included in the analysis, patients had to have a positive RT-PCR for SARS-CoV-2 and be admitted in any department of AP-HP. Patients with previous history of any MSK condition were excluded. MSK conditions were considered if occurring up to 90days after the positive RT-PCR. Demographics and disease characteristics including treatment were compared in both groups (MSK yes/no) by t-test or Chi² test, accordingly.

RESULTS

In total, 17,771 patients had a positive SARS-CoV-2 RT-PCR at APHP and were admitted in any department of AP-HP. Among them, 15,601 had no previous history of MSK condition and among them, 1370 (8.8%) presented with MSK symptoms after the viral infection. The most prevalent MSK symptoms were back pain (32.9%), followed by arthralgia (29.9%), radicular pain (20.2%) and arthritis (22.8%). Patients with MSK symptoms (MSK+) were older (67 y vs. 64 y, P<0.01), more frequently obese (29% vs. 25%, P=0.03), hypertensive (34% vs. 30%, P<0.01) and with diabetes (21% vs. 18%, P<0.01). Treatment for SARS-CoV-2 was slightly different in both groups, with higher corticosteroids (40.7% vs. 29.0%, P<0.01), antivirals (21.5% vs. 15.3%, P<0.01) and immunosuppressors (8.5% vs. 4.5%, P<0.01) prescription rates in the MSK+ group.

CONCLUSION

MSK symptoms occurred in almost 9% of patients admitted to the hospital after a SARS-CoV-2 infection, particularly in older and more comorbid patients. Further analysis evaluating whether these symptoms remain over time are needed.

Coronavirus disease 2019 and pityriasis rosea: A review of the immunological connection

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is characterized by the activation of a cytokine storm derived from an excess release of cytokine (interleukin [IL]-6, interferon [IFN] I, C-X-C motif chemokine ligand [CXCL]10, tumor necrosis factor [TNF]-α, macrophage inflammatory protein [MIP]1) due to an uncontrolled immune activation. There has been a fivefold increase in the number of cases of pityriasis rosea during the SARS-CoV-2 pandemic. Using the keywords "pityriasis" and "COVID-19", we carried out a PubMed search, including all articles in the English language published until November 2021. We aimed to investigate the possible connection between SARS-CoV-2 and pityriasis rosea (PR). Pityriasis could be considered an immunological disease due to the involvement of cytokines and chemokines. Our analysis yielded 65 articles of which 53 were not considered; the others (n = 12) concerning the association between PR and COVID-19 were included in our study. We suggest two mechanisms underlying the involvement of the skin in viral infections: (i) viruses directly affecting the skin and/or inducing host immune response thus causing cutaneous manifestations; and (ii) viruses as a possible inducer of the reactivation of another virus. The first mechanism is probably related to a release of pro-inflammatory cytokine and infection-related biomarkers; in the second, several pathways could be involved in the reactivation of other latent viruses (human herpesviruses 6 and 7), such as a cytokine-cytokine receptor interaction, the Janus kinase-signal transducer and activator of transcription signaling pathway, and the IL-17 signaling pathway. We thus believe that a cytokine storm could be directly or indirectly responsible for a cutaneous manifestation. More investigations are needed to find specific pathways involved and thus confirm our speculations.

Long COVID from rheumatology perspective - a narrative review

Long-term sequel of acute COVID-19, commonly referred to as long COVID, has affected millions of patients worldwide. Long COVID patients display persistent or relapsing and remitting symptoms that include fatigue, breathlessness, cough, myalgia, arthralgia, sleep disturbance, cognitive impairment and skin rashes. Due to the shared clinical features, laboratory and imaging findings, long COVID could mimic rheumatic disease posing a diagnostic challenge. Our comprehensive literature review will help rheumatologist to be aware of long COVID manifestations and differentiating features from rheumatic diseases to ensure a timely and correct diagnosis is reached.

Association between alopecia areata and COVID-19: A Systematic Review

Background

COVID-19 may play a role in various immune-related dermatologic conditions. The relationship between COVID-19 and alopecia areata remains unclear.

Objective

To review the existing literature for clinical studies and reports investigating the association between new-onset alopecia areata or the exacerbation of preexisting alopecia areata following infection with SARS-CoV-2.

Methods

A systematic review of the literature was performed using PubMed, Embase, and MEDLINE databases from inception to October 2021. Included articles assessed alopecia areata following infection with SARS-CoV-2.

Results

Of 402 total articles, 9 were identified as meeting the inclusion criteria. Six articles described case reports of 7 patients with new-onset alopecia areata following confirmed infection with SARS-CoV-2, and 3 articles reported on alopecia areata recurrence or exacerbation following SARS-CoV-2 infection in patients with preexisting disease. Studies investigating the exacerbation or recurrence of alopecia areata following infection reported mixed findings.

Limitations

A majority of the included studies were case reports. The heterogeneity of articles precluded data synthesis.

Conclusion

Alopecia areata may be a dermatologic manifestation of COVID-19, with cases most often appearing 1 to 2 months following infection. Additional research is necessary to better elucidate the relationship and draw conclusions.

Extra-Pulmonary Complications in SARS-CoV-2 Infection: A Comprehensive Multi Organ-System Review

Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, is typically presented with acute symptoms affecting upper and lower respiratory systems. As the current pandemic progresses, COVID-19 patients are experiencing a series of nonspecific or atypical extra-pulmonary complications such as systemic inflammation, hypercoagulability state, and dysregulation of the renin-angiotensin-aldosterone system (RAAS). These manifestations often delay testing, diagnosis, and the urge to seek effective treatment. Although the pathophysiology of these complications is not clearly understood, the incidence of COVID-19 increases with age and the presence of pre-existing conditions. This review article outlines the pathophysiology and clinical impact of SARS-CoV-2 infection on extra-pulmonary systems. Understanding the broad spectrum of atypical extra-pulmonary manifestations of COVID-19 should increase disease surveillance, restrict transmission, and most importantly prevent multiple organ-system complications.
