Abstract
The novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a pandemic threatening global public health. In the current paper, we describe our successful treatment of three COVID-19 pneumonia patients cases including severe cases and cases with mortality risk factors. One 32-year-old male COVID-19 patient was diagnosed with severe COVID-19 pneumonia and moderate ARDS. The second COVID-19 pneumonia patient had a history of diabetes and chronic bronchitis. The third case of COVID-19 pneumonia was an 82-year old female patient. All three cases had severe COVID pneumonia and therefore were aggressively managed with a multidisciplinary and personalized therapeutic approach that included nutritional support, antiviral pharmacotherapy, active control of comorbidities, prevention of complication development and psychological intervention. Our experience highlights the importance of the use of a multidisciplinary therapeutic approach that tailors to the specific condition of the patient in achieving a favorable clinical outcome.

The patient resided within one kilometer of Huanan Seafood Wholesale Market in Wuhan city, China, the epicenter of the COVID-19 outbreak. On January 27, 2020, the patient developed fatigue without an apparent cause and had 5-6 watery stools/day. He had no fever, nausea, vomiting, or abdominal pain. Cough with scant foamy sputum and difficulty in breathing during activity developed on February 1, 2020. The patient took over the counter (OTC) cold medicine for 2 days to no avail. On February 3, his breathing difficulty was worsened, chest x ray at a local hospital revealed lung infection and was referred to our hospital.</p><p id="p0025">Admission examination showed a temperature of 36 °C, a pulse of 85/min, a respiratory rate of 35/min, a blood pressure of 117/84 mmHg. Physical examination showed no abnormalities. Laboratory studies showed increased white blood cell (WBC) count (17.64 × 10<sup>9</sup>/L; normal references: 4–10 × 10<sup>9</sup>), neutrophil count (15.45 × 10<sup>9</sup>/L; normal references: 2.0–7.0 × 10<sup>9</sup>), and lymphocyte count (0.6 × 10<sup>9</sup>/L; normal references: 0.8–4.0 × 10<sup>9</sup>). Blood chemistries revealed elevations in C-reactive protein (CRP) (348.56 mg/L; normal references: 0.00–8.20 mg/L), and erythrocyte sedimentation rate (ESR,140 mm/h; normal references: 0–15 mm/h), fasting plasma glucose (FPG, 7.13 mmol/L; normal references: 3.9–6.10 mmol/L), alanine aminotransferase (ALT, 70 U/L; normal references: 5–40 U/L), aspartate aminotransferase (AST, 63 U/L; normal references: 8–40 U/L), blood urea nitrogen (BUN, 11.21 mmol/L; normal references: 2.9–8.2 mmol/L), and procalcitonin (PCT, 0.162 ng/mL; normal references: <0.046 ng/mL).
