ABSTRACT
Sarcoidosis is a heterogeneous inflammatory disease of unknown cause. The main symptom of the disease are noncaseating granulomas. Regardless of the unknown etiology, the trigger may be cross-reactions to an infectious antigen. As such, COVID-19 infection may also be considered. Although the virus mainly affects the lungs, we are increasingly confronted with its extrapulmonary manifestations. Several cases of sarcoidosis-like manifestations associated with COVID-19 have been described in the literature to date. A 52-year-old man was admitted to the Clinic of Rheumatology at MHAT "Sv. Marina "-Varna with joint pain syndrome, swelling of the wrists, the presence of rapidly growing, painless tumors on the extensor surfaces of the right wrist and forearm, as well as in the left knee. Complaints appeared two months after suffering from COVID-19 viral infection. The patient underwent a number of studies that proved the presence of a pathological process in soft tissues. Histopathological examinations proved the presence of a noncaseating granulomatous process. Despite the lack of complaints from the respiratory system, a CT scan of the chest was performed, which revealed hilar lymphadenopathy. In recent months we have witnessed the appearance of various pathological conditions that develop after suffering from COVID-19 viral infection. Only a few cases of sarcoid-like granulomas have been reported in the literature. Due to the short time from disease to granuloma, noncaseating granulomas are thought to be a sarcoid-like immune response to SARS-CoV-2.
ABSTRACT
Over the last year, the concept of coronavirus disease 2019 (COVID-19) has undergone a major shift. Our initial understanding of COVID-19 as a flu-like illness was rethought as a polysyndromic inflammatory disease involving not only the respiratory system but also the musculoskeletal system, the skin, the cardiovascular system, and the genitourinary system. Within this inflammatory condition, the tissue damage is immunemediated, resembling the exacerbations of a full-blown rheumatic disease. Our aim was to describe the frequency and type of rheumatic manifestations in a cohort of patients with COVID-19 hospitalized in the Rheumatology Department for COVID-19 at Sv. Marina University Hospital, Varna, Bulgaria. In the current single-center cohort study, a retrospective database analysis was performed among all COVID-19 patients hospitalized from 1 December 2020 to 22 January 2021. All 243 patients (aged 19-93 years) were treated for moderate or severe SARS-CoV-2 infection confirmed by laboratory tests, including a positive polymerase chain reaction (PCR) test and imaging. Inpatient treatment includes dexamethasone, anticoagulants, antibiotics and the antiviral drug remdesevir (at clinical judgment). A detailed medical history and clinical examination were performed by a rheumatologist and/or internal medicine specialist. Among all 243 patients with COVID-19, those with a history of myalgia and arthralgia were 26% (n = 63) and 21.3% (n = 52), respectively. We found 4 (1.6%) cases of emerging cutaneous vasculitis and 2 (0.8%) cases of severe Raynaud's phenomenon after the onset of SARS-CoV-2 infection. Two patients had severe muscle weakness, elevated creatine phosphokinase, and were diagnosed with inflammatory myopathy caused by COVID-19. Lupus-like syndrome was observed in 2 (0.8%) patients. Rheumatic manifestations are part of the heterogeneous spectrum of COVID-19 disease. Amidst the COVID-19 pandemic, any newly onset rheumatic manifestation requires the exclusion of SARS-CoV-2 infection. Therefore, the rheumatologist should be a part of a multidisciplinary approach to the treatment of COVID-19.
ABSTRACT
Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. COVID-19 is caused by a virus called severe acute respiratory syndrome coronavirus 2 or SARS-CoV-2. The impact of the pandemic has led to significant research on all aspects of the disease, including diagnostic biomarkers, related risk factors and strategies that could be used for its treatment and prevention. To this end, eosinopenia has been identified as one of many factors that could facilitate diagnosis and have prognostic value in cases of severe COVID-19. While eosinophil-associated conditions have been misdiagnosed as COVID-19 and others are among the reported complications, patients with pre-existing eosinophil-associated diseases (e.g. asthma, eosinophilic gastrointestinal diseases) do not appear to be at increased risk of severe disease. Interestingly, several recent studies have shown that a diagnosis of asthma may be associated with some degree of protection. We present a 42-year-old patient with eosinophilic granulomatosis with polyangiitis (Church-Strauss vasculitis) known for 4 years, who in March 2021 was diagnosed with COVID-19 infection. The disease was presented with manifestations of acute viral infection, with observed post-COVID transient migrating nodules of subcutaneous adipose tissue on the limbs, percentage of eosinophils over 50 and complete recovery.
