City-dwelling children from Kenya who were infected with human immunodeficiency virus type 1 (HIV-1) were tested for coinfection with cytomegalovirus (CMV), human T cell lymphotropic viruses 1 and 2, Kaposi sarcoma-associated herpesvirus (KSHV), or hepatitis B, C, and G viruses. All children were found to be coinfected with CMV, whereas 5% had hepatitis G virus coinfection and 15% had KSHV coin...

OBJECTIVES: We aimed to identify demographic and behavioural determinants associated with risk of repeat STI infection and coinfection with gonorrhea and chlamydia in the Regina Qu’Appelle Health Region, Saskatchewan. METHODS: We extracted data from a cross-sectional sample of laboratory-confirmed gonorrhea cases between 2003 and 2012 from the notifiable disease files of the Regina Qu’Appelle H...

BACKGROUND The aetiology and factors leading to the progression of laryngeal cancer are still unclear. Although human papillomavirus (HPV) has been suggested to play a role, reports concerning the effect of HPV infection on tumour development are controversial. Recently, transfusion transmitted virus (TTV) was suggested to play a role in certain infections as a causative or coinfecting agent. ...

This prospective multicenter study evaluated separately the significance of maternal injection drug use (IDU) and human immunodeficiency virus type 1 (HIV-1) coinfection in vertical transmission of hepatitis C virus (HCV). In all, 1372 consecutive, unselected HCV antibody-positive mothers and their infants were studied. Maternal HIV-1 coinfection (crude odds ratios [OR], 1.41; 95% confidence in...

Our earlier study demonstrated high prevalence of multiple human papillomavirus (HPV) infection in patients with invasive uterine cervical cancer, including squamous cell carcinoma (SCC). HPV 16 is the most predominant genotype related to SCC of the uterine cervix. The aim of this study was to reveal the biological significance of multiple HPV infection concerning the tumor progression of invas...

Dengue fever and scrub typhus are common causes of acute febrile illness of unclear origin in Asia. Though coinfections of many vector-borne diseases have been described, articles on dengue and scrub typhus coinfection are distinctly limited. In case of coinfection with dengue and scrub typhus, vigilant monitoring of vitals, platelets transfusion, and timely treatment with doxycycline are neces...

The incidence of necrotic enteritis (NE) due to Clostridium perfringens (CP) infection in commercial poultry has been increasing at an alarming rate. Although pre-exposure of chickens to coccidia infections is believed to be one of the major risk factors leading to NE, the underlying mechanisms of CP virulence remain undefined. The objectives of this study were to utilize an experimental model ...

BACKGROUND HBV/HCV coinfection is a common finding among hemodialysis patients. However, there is scarce information concerning the impact of HBV coinfection on the response to treatment of HCV-infected patients on hemodialysis. AIM We aimed to compare the rate of sustained virologic response (SVR) to treatment with interferon-alfa (IFN) between hemodialysis patients with HBV/HCV coinfection ...

HIV and hepatitis B virus (HBV) coinfection increases HIV and HBV replication, hepatitis flares, and risk of progression to chronic HBV infection, cirrhosis, and hepatocellular carcinoma. HIV and HBV coinfection decreases frequency of hepatitis Be antibody (anti-HBe) and hepatitis B surface antibody (anti-HBs) seroconversion, increases risk of antiretroviral therapy-related hepatotoxicity, and ...
