Treatment for COVID-19-a cohort study from Northern Italy.

Multicentre, retrospective cohort study with multivariable Cox proportional-hazards modelling and survival-time inverse-probability-weighting, evaluating the impact of different treatments on survival of proven COVID-19 patients admitted to two Hospitals in the province of Piacenza, Italy. Use of tocilizumab and of high doses of low molecular weight heparin, but not of antivirals (either alone or in combination), azithromycin, and any corticosteroid, was independently associated with lower mortality. Our results support further clinical evaluation of high doses of low molecular weight heparin and tocilizumab as COVID-19 therapeutics.

Case Report: B Lymphocyte Disorders Under COVID-19 Inflammatory Pressure.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infects humans through the angiotensin converting enzyme-2 (ACE-2) receptor expressed on many cells, including lymphocytes. In Covid-19 patients IL-6 is overexpressed, and hyperactivated plasmacytoid lymphocytes are detected in peripheral blood film. We hypothesize that, due to the unpredictable interaction between the new virus and the B cell lineage of infected patients, a cascade of out of control events can ensue, capable of determining unexpected pathologic disorders involving such lineage. Here we report two cases of autoimmune hemolytic anemia (AIHA) and two cases of B-cell hematological malignancies developed or reactivated during acute SARS-CoV-2 infection. The temporal relationship of the events may suggest a potential causal relationship between SARS-CoV-2 infection and the hematopoietic disorders. We suggest that special attention should be paid to COVID-19 patients with underlining B cell lineage disorders.

Adherence to ursodeoxycholic acid therapy in patients with cholestatic and autoimmune liver disease.

BACKGROUND: Ursodeoxycholic acid (UDCA) is used for treatment of cholestatic liver diseases and may improve long-term outcome. Although treatment with this hydrophilic bile acid is virtually without side effects, medication adherence might be suboptimal due to patient misconceptions, compromising clinical outcome. Our aim was to evaluate adherence to UDCA in relation to patient beliefs about medicine and to identify potential predictors of poor adherence. METHODS: Prospective open-label study recruiting patients in treatment with UDCA from April 2016 to March 2017. Adherence was assessed both by the Sensemedic dispenser and by patient-reported adherence, during 12 weeks. Good adherence was defined as ≥ 80% intake. Quality of life (by SF-36) and beliefs about medicine (by BMQ) were also assessed. RESULTS: A total of 75 patients were enrolled (32% primary biliary cholangitis, 31% autoimmune hepatitis, 29% primary sclerosing cholangitis and 8% other conditions). Average adherence according to the medication dispenser was 92 ± 16% (range: 17-100). Eighty-nine percent of the patients exhibited good adherence and 11% poor adherence. According to the BMQ, 42% of all patients were accepting, 50% ambivalent, 8% indifferent and 0% skeptical to UDCA treatment. Poor adherence was associated with young age (P = 0.029) and male gender (P = 0.021). CONCLUSIONS: Despite the excellent safety profile of UDCA, still a significant number of patients are poorly adherent. Young age and male sex are associated with poor adherence. Efforts should be made to identify patients with poor adherence and to improve their compliance to therapy.
