Coronavirus-2019 Disease with Pancytopenia with Leptospirosis and Herpes Simplex Virus Co-infection

ABSTRACT

Aim and background: COVID-19 pandemic has affected the whole world. Besides COVID, many infections may emerge during the course of the disease. Lymphopenia, use of immunosuppressants underlying comorbidities, and immune dysregulation secondary to SARS-CoV-2 could be the likely cause of the emergence such infections. We hereby describe a case of COVID-19 disease which presented with pancytopenia and was found to have Leptospirosis and Herpes Simplex Virus co-infection. Case summary: A 23-yearold postpartum female with no comorbidities and uneventful obstetric history was referred to our hospital 2 weeks after a full-term normal vaginal delivery. She developed generalized convulsive status epilepticus on the 10th day of her delivery, which was managed elsewhere with anti-epileptic drugs (AEDs). During her hospital stay, RTPCR for COVID-19 turned out to be positive but she remained asymptomatic throughout the course of her illness and seizures remained well-controlled on AEDs. On admission to our hospital, she was fully conscious, alert with no focal neurological deficits. Notable findings on evaluation were pancytopenia with megaloblastic features, bilateral pedal edema, and hepatosplenomegaly. NCCT brain was done which was suggestive of subarachnoid hemorrhage (SAH) along bilateral parietooccipital region for which conservative management was planned. 2D echocardiography was normal. Ultrasonography of abdomen revealed gross splenomegaly and mild hepatomegaly with mesenteric lymphadenopathy. NCCT thorax and abdomen were unremarkable apart from hepatosplenomegaly. In the panel sent for pancytopenia workup, IgM anti-HSV 1 antibodies turned out to be positive in blood. In addition, tropical workup was suggestive of Leptospirosis (IgM antibodies were positive). Workup for tuberculosis was negative. Bone marrow workup revealed features of trilineage hematopoiesis with micronormoblastic maturation consistent with iron deficiency anemia with no evidence of hemophagocytosis. Subsequently, IV acyclovir, IV doxycycline, and iron replacement were added. She improved clinically after these therapies and was subsequently discharged in a stable condition. MRI brain with MR angiography and venography done before discharge showed T1 sulcal hyperintensities along bilateral parietooccipital regions suggestive of SAH which was not progressing (as compared to NCCT brain scan done at admission). On day 60 of telephonic follow-up, patient was doing well and leading normal life without any persistence or emergence of symptoms.
