COVID-19 with Extreme Thrombocytosis: A Case Report and Its Possible Mechanisms.

Background: Coronavirus Disease 2019 (COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has spread globally becoming a pandemic. The clinical manifestations of COVID-19 vary from asymptomatic to symptomatic disease. Hematologic manifestation which is commonly found in COVID-19 patients is thrombocytopenia whereas thrombocytosis is rarely reported. Case Presentation: We report a case of a 55-year-old woman with one week history of fever which spike along the day, dry cough, anosmia, nausea, epigastric pain and loss of appetite. She lived in local transmission area. The patient was diagnosed as mild suspected COVID-19 and confirmed with nasopharyngeal and oropharyngeal swab test (positive result). On admission, the number of platelet count was within normal limit but progressively increased exceeding 1000 x109/L accompanied by worsening of the clinical condition. Interestingly, to our knowledge, no such case has ever been reported. In this study, we will discuss the possible mechanisms of its changes. Conclusions: COVID-19 can present with extreme thrombocytosis. Thus, monitoring the platelet count during hospitalization can be helpful for anticipating worsening conditions and progression of COVID-19.

Delayed RT-PCR Time-To-Positivity in an adult with SARS-CoV-2 Infection.

Early diagnosis is among the crucial measures to control the spread of SARS-CoV-2 infection. To date, reverse transcription polymerase chain reaction (RT-PCR) is the gold standard for COVID-19 testing, but various factors can affect its performance leading to false negative results. Hereby we present a patient with a high clinical suspicion for COVID-19 and had multiple negative RT-PCR results over 5 days. A 22-year-old woman presented with fever, dry cough, nausea, myalgia, headache, and mild dyspnea. Eleven days before, she was in close contact with her father who had tested positive for COVID-19. RT-PCR on nasopharyngeal and oropharyngeal swabs were performed on day 8, 9, and 12 of illness which all came back negative even after she started having a worsening dyspnea and showing an increased lung opacity from radiographic findings on day 11 of illness. Interestingly, her rapid antibody test (VivaDiag™ COVID-19 IgM/IgG rapid test by VivaChek Biotech (HangZhou,China) was positive for anti-SARS-CoV-2 Ig M and Ig G. Due to the worsening condition, she was referred to a tertiary hospital where her RT PCR result was positive on day 13 of illness. After 28 days from her first symptom, she was discharged from the hospital with improved symptoms and chest X-ray. As conclusions, in patients with high suspicion of COVID-19, repeat swab tests are mandatory if previous tests were negative. The diagnosis and treatment plan of COVID-19 should not solely be based on RT-PCR, but also consider the patient's history, symptoms, laboratory result, and radiographic findings.

Association between clinical, laboratory findings and chest CT in COVID-19 in a secondary hospital in Jakarta, Indonesia.

INTRODUCTION: A new emerging infectious disease caused by SARS-CoV-2 has caused a global pandemic. Early diagnosis is essential to prevent and halt the spread of the disease, patient management and isolation. In this study, we aimed to reveal correlations between clinical and laboratory findings with chest CT. METHODS: This in an observational case series single center study in a secondary hospital in Jakarta, Indonesia. Patients were included if they had typical symptoms and positive RT-PCR for SARS-CoV-2. RESULTS: Forty-two patients with positive RT-PCR were included in this study. Typical CT findings were present in 33 (78.6%). We found a positive correlation between patients in whom the imaging was performed after the 4th day of symptoms and chest CT findings (r=0.365 p<0.05). In receiver operating characteristic analysis of this parameter, the area under curve (AUC) was 0.678, and the sensitivity and specificity were 0.96 and 0.44, respectively. CONCLUSIONS: Early diagnosis of COVID-19 is essential to promptly isolate and treat suspected patients. Utilization of chest CT to help diagnosis in this pandemic era needs to be considered by healthcare facilities especially if RT-PCR is limited.

Clinical, Radiological Features and Outcome of COVID-19 patients in a Secondary Hospital in Jakarta, Indonesia.

INTRODUCTION: The numbers of people infected with SARS-CoV-2 in Indonesia especially in Jakarta as the epicenter continue to rise. Limited published clinical data, scarcity and long turn over time of diagnostic testing put clinician in dilemma to make diagnosis. METHODOLOGY: This is an observational case series study from confirmed COVID-19 patient in our hospital from first case admission on 17 March 30 April, 2020. We collected patient's demography, symptoms, comorbidities, therapy, laboratory, chest x-ray and ECG consecutively. RESULTS: Between 17 March 2020 and 30 April 2020, there were 30 confirmed COVID-19 cases, 16 (53.3%) were male. Clinical symptoms were dyspnea in 22 (73.3%) and dry cough 16 (53.3%). Comorbidities were diabetes in 14 (46.6%), hypertension 10 (33.3%) and Coronary Artery Disease (CAD) in 10 (33.3%) patients respectively. Laboratory findings showed lymphopenia in 21 (70%) patients, increased inflammation marker in Erythrocyte Sedimentation Rate (ESR), C-Reactive Protein (CRP) and Lactate Dehydrogenase (LDH) 21 (70%), 23 (76.6%) and 12 (40%) patients respectively. Twenty-seven (90%) cases had abnormal Chest X-Ray (CXR) and mostly severe 18 (60%). Descriptive finding for images included consolidation 16 (53.3%) and Ground Glass Opacities (GGO) in 10 (33.3%) patients. CONCLUSIONS: Based on our findings, most cases of COVID-19 admitted in secondary referral hospital were already in moderate to severe stages. This is most likely due to late referral from primary care and unspecific clinical features resemblance of other infectious diseases. Inflammation marker and CXR are cost effective findings and can be used as marker to determine further referral.
