Clinical and laboratory evaluation of patients with SARS-CoV-2 pneumonia treated with high-titer convalescent plasma.

Here, we report on a phase IIa study to determine the intubation rate, survival, viral clearance, and development of endogenous Abs in patients with COVID-19 pneumonia treated with convalescent plasma (CCP) containing high levels of neutralizing anti-SARS-CoV-2 Abs. Radiographic and laboratory evaluation confirmed all 51 treated patients had COVID-19 pneumonia. Fresh or frozen CCP from donors with high titers of neutralizing Abs was administered. The nonmechanically ventilated patients (n = 36) had an intubation rate of 13.9% and a 30-day survival rate of 88.9%, and the overall survival rate for a comparative group based on network data was 72.5% (1625/2241). Patients had negative nasopharyngeal swab rates of 43.8% and 73.0% on days 10 and 30, respectively. Patients mechanically ventilated had a day-30 mortality rate of 46.7%; the mortality rate for a comparative group based on network data was 71.0% (369/520). All evaluable patients were found to have neutralizing Abs on day 3 (n = 47), and all but 1 patient had Abs on days 30 and 60. The only adverse event was a mild rash. In this study on patients with COVID-19 disease, we show therapeutic use of CCP was safe and conferred transfer of Abs, while preserving endogenous immune response.

Case Report: Non-infectious causes of palmoplantar rashes, what to consider.

Background: Palm and sole skin eruptions have a broad differential diagnosis. It is particularly important to recognize common causes as well as their association with certain chemotherapy regimens such as Capecitabine. Case report: A 79-year-old woman presented with a painful rash on her hands and feet for 1 week. She had metastatic colon cancer and was in her third week of treatment with capecitabine. Her diagnosis was a medication side-effect from chemotherapy. Capecitabine was stopped and she had some clinical improvement over the next two days. She was discharged with oncology follow up for resumption of Capecitabine at a lower dose with improvement in her rash 3 weeks later. Discussion: Skin rashes are a commonly encountered complaint in patients in the inpatient and outpatient setting. It is important to maintain a broad differential diagnosis in those with rashes of the palmoplantar surfaces of the hands and feet. Recognizing skin changes as a possible manifestation of underlying malignancy or a medication side-effect is key in appropriate diagnosis and treatment.

Case Report: Hepatopulmonary syndrome as the first clinical manifestation of cirrhosis in a patient with underlying chronic lung disease.

An 86 year old woman with multiple chronic lung diseases (including chronic obstructive pulmonary disease, bronchiectasis, and untreated mycobacterium avium-intracellulare) presented with two weeks of increased shortness of breath, notably worse when seated as compared to when lying down. After treatments focused on her known conditions did not resolve her dyspnea, the differential diagnosis was broadened and she was found to have evidence of cirrhosis on imaging. As a result of this new diagnosis, transthoracic echocardiography and arterial blood gas analysis were performed and together yielded the diagnosis of hepatopulmonary syndrome. We describe a rare presentation of hepatopulmonary syndrome manifesting as a patient's first clinical evidence of suspected cirrhosis, a diagnosis made difficult by this patient's numerous other lung diseases which muddied the picture.
