Correspondence: semen parameters in men who recovered from covid-19 - a systematic review and meta-analysis.

A recent systematic review with meta-analysis performed by Tiwari et al. (Middle East Fertil Soc J 26:44, 2021) suggested that coronavirus disease 2019 (COVID-19) affects both semen parameters and sexual hormones. However, we have observed a few inconsistencies in their systematic review methods and their synthesis of results (meta-analysis), which would have impacted their results.

Analysis of the sustained virological response in patients with chronic hepatitis C and liver steatosis.

Context: Chronic hepatitis C as well as non-alcoholic fatty liver disease are recognized as the main cause of liver disease in Western countries. It is common to see the concomitance of the diseases and the influence of steatosis in the sustained virological response of patients with hepatitis C virus.

Objective: Assess the sustained virological response in chronic hepatitis C patients according to the presence of liver steatosis.

[Evaluation of the cellular immunity in patients coinfected by the hepatitis C virus and the human immunodeficiency virus].

Background: The immune activation provoked by the hepatitis C virus can be deleterious in patients with human immunodeficiency virus, favouring the destruction of CD4 cells. By the other side, the immune restoration observed after the onset of antiretroviral therapy can be partially obscured in patients with the hepatitis C virus.

Aim: The objective of the present study was to evaluate the impact of coinfection by hepatitis C virus and the human immunodeficiency virus in the cellular immunity.

[Steatosis and non-alcoholic steatohepatitis in patients with chronic hepatitis due to hepatitis C virus infection].

Background: [corrected] Hepatic steatosis is a common finding in patients with hepatitis C, mainly virus C genotype 3. Steatosis in these cases might be associated with antiviral treatment response and with prognosis of chronic hepatitis.

Aims: To determine the presence of steatosis and non-alcoholic steatohepatitis in chronic hepatitis C and its correlation with genotype and hepatic fibrosis.

[Ambulatorial prevalence of hepatitis B and C markers in patients with human immunodeficiency virus infection in a general hospital].

Background: Hepatitis B and C viruses and human immunodeficiency virus share the same route of transmission, and the prevalence of HBV and HCV infection in patients infected with HIV is greater than it is in the general population.

Aim: To determine the prevalence of hepatitis B and C markers in a population of patients with HIV as well as the risk factors involved.

Patients And Methods: From 5,870 registration forms of patients with HIV of an Infectology Unit, 587 were randomly selected.
