BACKGROUND The effect of coronavirus disease 2019 on the immune system is increasingly recognized. When severe, it causes immune dysregulation that may favor other infections, including Herpesviridae. Cytomegalovirus shares many innate immune pathways with severe acute respiratory syndrome coronavirus 2, which may potentiate each other. We describe a case of cytomegalovirus pneumonitis complicating the course of coronavirus disease 2019 in a patient with systemic lupus erythematosus/systemic sclerosis overlap and usual interstitial pneumonia, mimicking interstitial lung disease exacerbation. To the best of the authors' knowledge, this is the first case to be reported worldwide in the setting of connective tissue disease-associated interstitial lung disease. METHODS We describe the case of a 47-year-old white/Yemeni female who is known to have systemic lupus erythematosus/scleroderma overlap and usual interstitial pneumonia who was initially admitted with severe coronavirus disease 2019 pneumonia mandating intensive care. After initial improvement, it was later complicated with cytomegalovirus pneumonitis, mimicking interstitial lung disease exacerbation. The case was successfully treated with ganciclovir. CONCLUSIONS Intriguingly, severe acute respiratory syndrome coronavirus 2 and cytomegalovirus may potentiate each other, since they share some innate immune pathways. Subjects with severe coronavirus disease 2019 and underlying connective tissue diseases and those who are immunosuppressed carry higher risk compared with other cohorts, which may mandate active surveillance for cytomegalovirus coinfection or reactivation. Among various immunosuppressive therapies that has been tried for cytokine storm, use of anti-interleukin-6 inhibitors in the aforementioned population may carry more harm than previously thought, which may suggest that is reasonable to omit its use in treating this group with coronavirus disease 2019. This case underlines an underrecognized and underreported cause of morbidity and mortality during the course of severe coronavirus disease 2019 and will help to alert clinicians of its occurrence.

D000086382 COVID-19 A viral disorder generally characterized by high FEVER; COUGH; DYSPNEA; CHILLS; PERSISTENT TREMOR; MUSCLE PAIN; HEADACHE; SORE THROAT; a new loss of taste and/or smell (see AGEUSIA and ANOSMIA) and other symptoms of a VIRAL PNEUMONIA. In severe cases, a myriad of coagulopathy associated symptoms often correlating with COVID-19 severity is seen (e.g., BLOOD COAGULATION; THROMBOSIS; ACUTE RESPIRATORY DISTRESS SYNDROME; SEIZURES; HEART ATTACK; STROKE; multiple CEREBRAL INFARCTIONS; KIDNEY FAILURE; catastrophic ANTIPHOSPHOLIPID ANTIBODY SYNDROME and/or DISSEMINATED INTRAVASCULAR COAGULATION). In younger patients, rare inflammatory syndromes are sometimes associated with COVID-19 (e.g., atypical KAWASAKI SYNDROME; TOXIC SHOCK SYNDROME; pediatric multisystem inflammatory disease; and CYTOKINE STORM SYNDROME). A coronavirus, SARS-CoV-2, in the genus BETACORONAVIRUS is the causative agent. 2019 Novel Coronavirus Disease,2019 Novel Coronavirus Infection,2019-nCoV Disease,2019-nCoV Infection,COVID-19 Pandemic,COVID-19 Pandemics,COVID-19 Virus Disease,COVID-19 Virus Infection,Coronavirus Disease 2019,Coronavirus Disease-19,SARS Coronavirus 2 Infection,SARS-CoV-2 Infection,Severe Acute Respiratory Syndrome Coronavirus 2 Infection,COVID19,2019 nCoV Disease,2019 nCoV Infection,2019-nCoV Diseases,2019-nCoV Infections,COVID 19,COVID 19 Pandemic,COVID 19 Virus Disease,COVID 19 Virus Infection,COVID-19 Virus Diseases,COVID-19 Virus Infections,Coronavirus Disease 19,Disease 2019, Coronavirus,Disease, 2019-nCoV,Disease, COVID-19 Virus,Infection, 2019-nCoV,Infection, COVID-19 Virus,Infection, SARS-CoV-2,Pandemic, COVID-19,SARS CoV 2 Infection,SARS-CoV-2 Infections,Virus Disease, COVID-19,Virus Infection, COVID-19
