Dermatological manifestations associated with COVID-19 and COVID-19 vaccination: results from the Lebanese COVID registry.

BACKGROUND: A number of cutaneous manifestations and adverse cutaneous reactions have been associated with COVID-19 infection and vaccine. OBJECTIVES: A Lebanese national registry was established to characterize the dermatologic manifestations and adverse cutaneous reactions associated with COVID-19 infection and vaccination in a sample of the Lebanese population. METHODS: An observational cross-sectional study was conducted via a web-based clinical form distributed to physicians wishing to report their cases from May 2021 till May 2022. RESULTS: In total, 142 patients were entered in the registry, of which 133 were adults and nine were pediatric patients. The main dermatological manifestations reported with COVID-19 infection in the adult group were urticaria (32.9%), telogen effluvium (21.4%), morbilliform (10%), and papulosquamous (8.6%) eruptions. Urticaria was the most common adverse cutaneous reaction to the vaccine (33%). Interestingly, herpes zoster was triggered in 12 patients post vaccination in our series with this finding more frequently seen in patients above the age of 41 (P = 0.013). In the pediatric group, the most reported dermatological findings associated with COVID-19 infection were malar erythema (25%) and telogen effluvium (25%). One 16-year-old patient developed lichen planus after one dose of a COVID-19 vaccine. No deaths were reported in both age groups. CONCLUSION: This Lebanese registry adds more robust evidence that clinical manifestations of the COVID-19 virus and vaccine are diverse. More studies are necessary to establish the pathophysiology of these dermatological findings in the context of COVID-19 infection and vaccination.

Perception of the Lebanese Adults about Vaccination: A Survey.

INTRODUCTION: With the continuous spread and emergence of transmissible diseases, focusing on preventive measures is essential to decrease their incidence and spread. In addition to behavioral measures, vaccination is an optimal way to protect the population and eradicate infectious diseases. The majority are aware of children's vaccinations, while many might not know that adult vaccinations are also essential. OBJECTIVES: This study aims to understand the perception of Lebanese adults towards vaccination and their knowledge and awareness of its importance. This is a national cross-sectional study, conducted between January 2020 and January 2021. RESULTS: the data were collected from 1023 subjects, the majority being Lebanese, previously healthy, and with a graduate or post-graduate level of education. Out of these participants, 44.9% were advised to take vaccines, half of them by healthcare workers. The most common vaccine received during adult life is the Flu vaccine. Overall, 25.6% of the participants were unaware that they needed vaccines and 27.9% thought it is not indicated. Participants' knowledge about vaccination is variable. In total, 39.4% agree or are uncertain whether vaccines contain harmful chemicals and 48.4% believe that vaccines will trigger diseases. The level of education and occupation significantly enhances knowledge about vaccination. Some participants 27.3% are concerned about the vaccine's side effects. The group of young participants, graduates, and nonsmokers think that the vaccine is a necessity and had a positive attitude towards vaccination. CONCLUSIONS: Many Lebanese lack knowledge about adult vaccination protection and its benefits in the community. It is essential that the country's health ministry department collaborate with the healthcare system to launch awareness campaigns about adult vaccination in the country to overcome the barriers and ensure better coverage.

Timing for Step-Down Therapy of Candidemia in Non-Neutropenic Patients: An International Multi-Center Study.

BACKGROUND: Candida bloodstream infection (BSI) remains one of the leading causes of BSI in critically ill and immunosuppressed cancer patients. In light of the changing epidemiology and rising resistant species, duration of treatment and appropriate timing of stepdown therapy from intravenous (IV) to oral antifungal agents are crucial for utmost disease control and overall survival. METHOD: We performed a multicenter retrospective study, with 119 non-neutropenic patients enrolled from four different medical institutions in Brazil, Lebanon, Spain and the United States, to assess the duration of IV therapy and appropriate time to step-down to oral therapy in adult patients, 14 years of age and older, with documented candidemia. The analysis was done using the statistical program R and SAS v9.4. Descriptive statistics are presented as frequencies and tables and the Fisher exact test was used to test the association between the categorical variables: organism, cancer, country, antifungal drug and duration of therapy, and time of step-down. RESULTS: Candida albicans contributed to 45% of bloodstream infection versus 55% of infection caused by Candida non-albicans. The three most common Candida non-albicans are: Candida glabrata 24%, Candida parapsilosis 13% and Candida tropicalis 8%. Most (57%) of the patients were admitted to ICU, whereas 52% had underlying malignancy. Multivariate analysis showed that a stay at ICU or an underlying cancer requiring chemotherapy were independently associated with failure and death (p <0.001). The average total duration of therapy was 14 days in all patients and 16 days in those who responded and survived. Forty-five patients were stepped down to either fluconazole and/or voriconazole in association with clinical and microbiologic resolution of the candidemia. The average (and median) day of step-down was 5 days. Patients who had a stepdown had more favorable outcomes (78% survival) as compared to those with no stepdown (56% survival) (P = 0.022). However, the 20 patients who received 1-4 days of first IV treatment before a stepdown to oral azoles had a comparable outcome (20% mortality) to the 25 patients who received >5 days of treatment (24% mortality - p = 0.75). CONCLUSION: Our data support the IDSA guidelines in that the total duration of treatment for candidemia should be at least 14 days after a negative blood culture. However, in non-neutropenic cancer patients with candidemia, a step-down to oral azole therapy can safely take place early (within 4 days of initiating IV therapy) as long as the patient had clinical and microbiologic resolution of the bloodstream infections.

Fluconazole-induced acute generalized exanthematous pustulosis.

Acute generalized exanthematous pustulosis (AGEP) is a rare severe cutaneous adverse reaction usually caused by drugs. The annual incidence is one to five cases per million. It is characterized by an acute febrile episode, accompanied by numerous small primarily non-follicular, sterile pustules arising within large areas of edematous erythema. There have been several case reports to date of AGEP following exposure to antifungals. Terbinafine is most commonly implicated in AGEP. We report a case of 7-year-old boy who developed AGEP shortly after commencing oral fluconazole for Tinea capitis. To our knowledge, this is the fourth reported case of AGEP due to fluconazole.
