The epidemiological profile of HCV infection is evolving in Europe, as well as in Italy. We have previously showed genotype distributions and their dynamics in 2,153 HCV RNA positive patients living in Calabria, Southern Italy, over 11 years. In this study, we extend and update this information by evaluating a hospital-based cohort of 945 HCV RNA positive patients attending five hospitals in the Calabria Region from January 2011 to August 2013. We assessed rates of HCV genotypes according to age and gender and the dynamics of HCV genotype distribution over the 3-year period studied. Data showed that genotype 1b is the most prevalent, followed by subtypes 2a/2c and genotype 3. Genotype 4 exhibited an increase between 2011 and 2013. Also, we found a significant decrease in the median age of subjects infected with HCV genotype 3 and 4 during the period studied. Since HCV genotypes are important in epidemiology, pathogenesis and response to antiviral therapy, a continuous epidemiological surveillance is needed.

The inflammatory pseudotumour of the lung is a rare and non-malignant neoplasm, which can be asymptomatic or characterized by variable clinical expressions. This report refers to a case occurring in a young woman and presenting as a persistent airway obstructive syndrome. With regard to histopathologic characterization, the present case can be classified as a fibrous histiocytic subtype.

A 44-year-old male developed interstitial lung disease (ILD) during treatment with rituximab (375 mg/m2 weekly intravenous × 4 weeks) for the management of immune thrombocytopenia (ITP). After 1 month of treatment he developed dyspnea, fever (38.9 °C), an increase of C-reactive protein (CRP) and white blood cells with hypoxemia, and decreased platelets. Chest X-ray and high-resolution computed tomography revealed diffuse bilateral lung infiltrates. He was diagnosed with severe ILD; rituximab was discontinued, and treatment with fluticasone combined with salmeterol, methylprednisolone, and omeprazole was started, with an improvement of symptoms over 15 days with normalization in CRP at 30 days. A Naranjo assessment score of 6 was obtained, indicating a probable relationship between the patient’s symptoms and the suspect drug. In conclusion, in ITP patients treated with rituximab, we suggest evaluating pulmonary endpoints through pharmaco-epidemiological observational studies.
