Nails and COVID-19 - A comprehensive review of clinical findings and treatment

COVID-19 and Autoimmunity in Dermatology: A Moroccan Case Series and Literature Review

INTRODUCTION

Since the beginning of the pandemic, many skin manifestations associated with COVID-19 have been reported. New reports show that COVID-19 can lead to autoimmune diseases (AIDs) and autoinflammatory diseases, especially dermatological.

METHODS

A prospective study was conducted by the dermatology department of the Centre Hospitalier Universitaire Ibn Rochd (CHU Ibn Rochd) of Casablanca in Morocco since the beginning of the pandemic including 18 patients with COVID-19-related skin manifestations.

RESULTS

Eighteen cases were collected with confirmed SARS-CoV-2 infection. The mean COVID score was 0.7. A percentage (94.44%) of the cases had general symptoms. Skin involvement was variable, mainly maculopapular rash (44.44%), purpura (27.77%), urticaria, varicelliform rash, necrotic lesions of the face, and pityriasis rosea Gibert (PRG)-like lesions. Mucosal involvement was found in 50%. Viral reactivation was found in 5.55%. Telogen effluvium was found in 22.22%. Moreover, AID was triggered by COVID-19: lupus (11.11%), associated with antiphospholipid syndrome (APL Sd) (5.55%), psoriasis (11.11%), alopecia, and pemphigus. Severe toxidermia was potentiated by SARS-CoV-2 infection (22.22%): Stevens-Johnson syndrome (Sd), acute generalized exanthematous pustulosis (APEG), and drug reaction with eosinophilia and systemic symptoms (DRESS).

CONCLUSION

 The interest of this work is to report our experience during the COVID-19 pandemic to understand some pathophysiological mechanisms of its dermatological manifestations and to draw the attention of clinicians to the link of this infection with autoimmune and autoinflammatory diseases and toxidermia.

Onychomadesis in a COVID-19 patient

We report the case of a 67-year-old woman who developed onychomadesis on 9 of her fingers 2 months after recovering from COVID-19, with subsequent full nail regrowth after 4 months. The development of onychomadesis in COVID-19 is probably related to inhibition of nail proliferation due to fever, direct viral damage, or an inflammatory process associated with endothelial damage and obliterative microangiopathy in the nail matrix area. Clinicians should be aware of nail changes and actively seek them out in patients with COVID-19.

Defining the short-term and long-term skin manifestations of COVID-19: insights after more than three years of the pandemic

AIM

This review aimed to assess the impact of coronavirus disease 2019 (COVID-19) on skin health to establish a classification of the skin lesions that occur most frequently during the disease and whether a particular category of skin damage is more likely to occur both in the short term and in the long term.

METHODS

We conducted a literature search of the PubMed database. Ultimately, 109 articles were included in this review. The exact phrases∕syntax and connectors used for the database search∕query were as follows: "Coronavirus and skin", "COVID-19 and skin", "SARS-CoV-2 and skin", "Coronavirus cutaneous manifestations", "COVID-19 cutaneous manifestations", "SARS-CoV-2 cutaneous manifestations", "Coronavirus dermatology", "SARS-CoV-2 and dermatology", "COVID-19 and dermatology", "COVID-19 and skin eruption", "Coronavirus and skin rash", "COVID-19 and hair", "Coronavirus and hair", "Coronavirus and nails", "SARS-CoV-2 and hair", and "SARS-CoV-2 and nails". Only articles with abstracts referring strictly to cutaneous manifestations of COVID-19 were chosen. Articles without abstracts were not considered.

RESULTS

We established six of the most frequently reported clinical patterns associated with COVID-19 and their probability of occurring during COVID-19 disease evolution based on the current literature reports. We did not identify the particular types of skin lesions that are most prone to long-term persistence; most such cases are rare, and no conclusion can be drawn based on them.

CONCLUSIONS

Apart from classified COVID-19-related skin disorders, this pandemic has been a challenge for dermatologists and a wide range of cutaneous side effects related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) treatments have been reported. We are aware of other polymorphic clinical presentations, with novel data being reported periodically, but the pathophysiological mechanisms and evolution are largely unknown.

The effect of COVID-19 on development of hair and nail disorders: a Turkish multicenter, controlled study

BACKGROUND

A broad spectrum of skin diseases, including hair and nails, can be directly or indirectly triggered by COVID-19. It is aimed to examine the type and frequency of hair and nail disorders after COVID-19 infection.

METHODS

This is a multicenter study conducted on consecutive 2171 post-COVID-19 patients. Patients who developed hair and nail disorders and did not develop hair and nail disorders were recruited as subject and control groups. The type and frequency of hair and nail disorders were examined.

RESULTS

The rate of the previous admission in hospital due to COVID-19 was statistically significantly more common in patients who developed hair loss after getting infected with COVID-19 (P < 0.001). Telogen effluvium (85%) was the most common hair loss type followed by worsening of androgenetic alopecia (7%) after COVID-19 infection. The mean stress scores during and after getting infected with COVID-19 were 6.88 ± 2.77 and 3.64 ± 3.04, respectively, in the hair loss group and were 5.77 ± 3.18 and 2.81 ± 2.84, respectively, in the control group (P < 0.001, P < 0.001). The frequency of recurrent COVID-19 was statistically significantly higher in men with severe androgenetic alopecia (Grades 4-7 HNS) (P = 0.012; Odds ratio: 2.931 [1.222-7.027]). The most common nail disorders were leukonychia, onycholysis, Beau's lines, onychomadesis, and onychoschisis, respectively. The symptoms of COVID-19 were statistically significantly more common in patients having nail disorders after getting infected with COVID-19 when compared to the control group (P < 0.05).

CONCLUSION

The development of both nail and hair disorders after COVID-19 seems to be related to a history of severe COVID-19.

Identification, Mechanism, and Treatment of Skin Lesions in COVID-19: A Review

Coronavirus disease 2019 (COVID-19) is a multisystem disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), that primarily causes respiratory symptoms. However, an increasing number of cutaneous manifestations associated with this disease have been reported. The aim of this study is to analyze the scientific literature on cutaneous manifestations associated with SARS-CoV-2 by means of a narrative literature review until June 2021. The search was conducted in the following electronic databases: Medline (PubMed), SciELO, and Cochrane Library Plus. The most common cutaneous manifestations in patients with COVID-19 are vesicular eruptions, petechial/purpuric rashes, acral lesions, liveoid lesions, urticarial rash, and maculopapular-erythematous rash. These manifestations may be the first presenting symptoms of SARS-CoV-2 infection, as is the case with acral lesions, vesicular eruptions, and urticaria. In relation to severity, the presence of liveoid lesions may be associated with a more severe course of the disease. Treatment used for dermatological lesions includes therapy with anticoagulants, corticosteroids, and antihistamines. Knowledge of the dermatologic manifestations associated with SARS-CoV-2 contributes to the diagnosis of COVID-19 in patients with skin lesions associated with respiratory symptoms or in asymptomatic patients. In addition, understanding the dermatologic lesions associated with COVID-19 could be useful to establish a personalized care plan.

Nails and COVID-19 - A comprehensive review of clinical findings and treatment

The SARS‐CoV‐2 infection, responsible for COVID‐19, has raised the interest for infection‐associated muco‐cutaneous symptoms. While dermatologic symptoms in general gained an increasing awareness, affection of the nail organ has been mentioned only recently. We provide a narrative review on COVID‐19 manifestation on the nail organ and add symptoms induced by personal protective measures and SARS‐CoV‐2 vaccination. Available treatment options are discussed.
