Background/Aims: Spontaneous viral clearance of the chronic hepatitis C virus (HCV) in human immunodeficiency virus (HIV)-infected patients is a rare event. We aimed to identify the clinical, therapeutic, demographic, and laboratory features associated with spontaneous HCV clearance in 16 HIV-infected patients with chronic hepatitis C (CHC, the largest case series, to our knowledge). Methods: This case series study reports the findings from 16 HIV/HCV coinfected patients with CHC who experienced spontaneous clearance of HCV infection. Patients were monitored between 2000 and 2013 in the Infectious Diseases Outpatient Clinic at the Centro Hospitalar S. João, Porto, Portugal. Results: Apart from antiretroviral therapy (ART), all patients were also consuming other potential hepatotoxic drugs (e.g., alcohol, illicit drugs, methadone, and antituberculosis medication). In all but 1 of the 16 HIV-infected patients with CHC, viral remission was associated with a temporary suspension of the ART. All patients showed a sustained HCV viral clearance. Conclusion: A possible drug-induced liver injury and/or suspension of ART may, in some cases, contribute to increasing the chances of spontaneous HCV clearance in HIV-infected patients with CHC.

Background/aims: Hidradenitis suppurativa (HS), a chronic inflammatory skin disease of the hair follicle, can lead to scarring and disability. With an estimated European prevalence of 1%, few epidemiological studies of HS have been performed, and none focused on hospitalisations. We aimed to study the time trends of HS hospitalisations and to evaluate the demographic characteristics, hospital incidence rate, readmissions, length of stay, comorbidities and risk factors of hospitalised HS patients.Methods: We performed a retrospective observational study using a national administrative database in Portugal, with discharges between 2000 and 2014. All the inpatients aged 5 years or more with a diagnosis of HS were included. Variables analysed were age, sex, admission and discharge date, discharge outcome and diagnoses.Results: A total of 1,177 patients were hospitalised in this time period (48 were aged 18 years or younger) with a male-to-female ratio of 1:1.17. There was a hospital incidence rate of 0.83 patients with HS per 100,000 person-years (95% CI = 0.78-0.88). The age group with the highest incidence rate was 20-29 years among women and 40-49 years among men. We recorded an increasing trend in the number of new hospitalised patients and in the hospital incidence rate of HS. Tobacco was the most common comorbidity/risk factor. Eighty-three percent of our population underwent HS surgery.Conclusion: This hospital-based incidence study showed that admission for HS is increasing and that the majority of the HS inpatients were surgical cases. In the future, prospective studies will be important to assess risk factors for hospitalisations and complications. [ABSTRACT FROM AUTHOR]
