ABSTRACT
Introduction:
Human coronavirus NL63 (HCoV-NL63) is one of four common human respiratory coronaviruses. It causes lower respiratory tract infections in young children, elderly and immunosuppressed people, which could result in fatal outcomes. In this time of pandemic, we want to highlight the importance of other coronaviruses infection besides SARS-CoV-2, especially in a patient with underlying conditions like acute lymphoblastic leukemia, receiving immunosuppressive therapy that could result in humoral secondary immunodeficiencies. Case report We present the case of a 44-year-old Colombian man with acute lymphoblastic leukemia who developed HCoV-NL63 pulmonary infection after the first month of treatment with blinatumomab complicated with severe secondary hypogammaglobulinemia. HCoV-NL63 was detected by multiplex PCR, and HCoV-NL63 viral pneumonia was diagnosed. Hypogammaglobulinemia was studied by determining serum immunoglobulins levels and protein electrophoresis. The treatment consisted of supportive therapy and replacement with intravenous immunoglobulins. After therapy, the patient improved his oxygenation, and the infection was resolved in a few days.Conclusions:
This case highlights the relevance of other coronaviruses infections besides SARS-CoV-2 in patients receiving immunosuppressive therapy who develop secondary antibody deficiency, and the importance of replacement therapy with intravenous immunoglobulins at early stage of infection with HCoV-NL63.
