Prevalence and types of coinfections in sleeping sickness patients in kenya (2000/2009).

The occurrence of coinfections in human African trypanosomiasis (HAT) patients was investigated using a retrospective data of hospital records at the National Sleeping Sickness Referral Hospital in Alupe, Kenya. A total of 31 patients, 19 males and 12 females, were diagnosed with HAT between the years 2000 and 2009. The observed co-infections included malaria (100%), helminthosis (64.5%), typhoid (22.5%), urinary tract infections (16.1%), HIV (12.9%), and tuberculosis (3.2%). The species of helminthes observed included Ancylostoma duodenale (38.7%), Ascaris lumbricoides (45.7%), Strongyloides …

Species identification of trichomonads and associated coinfections in dogs with diarrhea and suspected trichomonosis.

Trichomonads have been infrequently reported in the feces of dogs where their pathogenicity remains uncertain. It is currently unknown whether Tritrichomonas foetus or Pentatrichomonas hominis is identified more commonly in dogs with trichomonosis or how often these infections are accompanied by concurrent enteric infectious agents. The objective of this study was to determine the identity of trichomonads present in a series of 38 unsolicited canine diarrheic fecal samples submitted for T. foetus diagnostic polymerase chain reaction (PCR) testing between 2007 and 2010. We also examined each fe

Molecular evidence of vector-borne pathogens coinfecting dogs from Poland.

Ticks of the genus Ixodes are vectors for many pathogens, including Borrelia burgdorferi sensu lato, Anaplasma phagocytophilum and Rickettsia spp., and may also serve as vectors for Bartonella spp. However, the role of ticks in Bartonella transmission requires additional studies. The aim of this study was to investigate whether coinfection with two or more vector-borne pathogens can occur in the following three groups of dogs: I - dogs with suspected borreliosis (N = 92), II - dogs considered healthy (N = 100), and III - dogs with diagnosed babesiosis (N = 50). Polymerase chain reactions were …

Development of fatal acute liver failure in HIV-HBV coinfected patients.

Coinfection with hepatitis B virus (HBV) is not uncommon in human immunodeficiency virus (HIV)-infected individuals and patients with HIV-HBV coinfection are at high risk for progression of liver disease. Current guidelines regarding the treatment of HIV infection recommend that patients who are coinfected with HIV and HBV receive highly active antiretroviral therapy (HAART) with activity against hepatitis B. While HIV-HBV coinfected patients often experience liver enzyme elevations after starting antiretroviral therapy, acute liver failure (ALF) is rare and typically occurs with older antiret…

Formal reasoning on qualitative models of coinfection of HIV and Tuberculosis and HAART therapy.

BACKGROUND: Several diseases, many of which nowadays pandemic, consist of multifactorial pathologies. Paradigmatic examples come from the immune response to pathogens, in which cases the effects of different infections combine together, yielding complex mutual feedback, often a positive one that boosts infection progression in a scenario that can easily become lethal. HIV is one such infection, which weakens the immune system favouring the insurgence of opportunistic infections, amongst which Tuberculosis (TB). The treatment with antiretroviral therapies has shown effective in reducing mortali

We report a case of acute urinary retention with meningoradiculoneuritis resulting from coinfection with varicella-zoster virus (VZV), HIV, and hepatitis B virus (HBV). The case is discussed in the context of other neurological syndromes associated with VZV and HIV infections, and of other viral causes of acute retention of urine.

Otosyphilis in HIV-coinfected individuals: a case series from Toronto, Canada.

We sought to identify and review the clinical features and treatment outcomes of eight recent cases of otosyphilis in HIV-positive patients seen in Toronto. All patients reported tinnitus, and seven (87.5%) reported subjective hearing loss. Not taking auditory findings into consideration, four patients would be classified as having secondary syphilis, three patients as having early latent syphilis, and one patient as having latent syphilis of unknown duration. The median CD4 cell count was 370 x 10(6)/L. All patients were treated with intravenous aqueous penicillin G with regimens recommended

Pathogenesis of hepatitis C virus coinfection in the brains of patients infected with HIV.

Involvement of the nervous system by human immunodeficiency virus (HIV) continues to be a serious problem. Among individuals with HIV who ha … t the hypothesis that HCV traffics into the HIV-infected brain, where it might lead to a productive coinfection associated with cognitive impairment.

Liver transplantation in HIV-HCV coinfected patients: a case-control study.

Liver transplantation (LT) for hepatitis C virus (HCV)-associated cirrhosis in human immunodeficiency virus (HIV)-infected patients was compared with non-HIV patients. Nine patients with HIV-HCV coinfection were compared with patients transplanted before and after each HIV patient (control group). Immunosuppression consisted in tacrolimus with steroids or mycophenolate mofetil. Acute cellular rejection and three-year actuarial patient survival were respectively 44% and 87.5% in HIV group and 22% and 93.7% in the control group (P=NS). Acute hepatitis C virus occurred earlier (2.3 vs. 4.3 months…

HIV and tuberculosis coinfection in the southern region of Ethiopia: a prospective epidemiological study.

HIV has played a key role in TB, modifying its incidence and clinical presentation. This study describes the prevalence of HIV among TB patients attending health facilities in the southern region of Ethiopia. The HIV prevalence was 18% for female and 21% for male TB patients. 15% and 30%, respectively, of the rural and urban patients with TB were HIV positive (p<0.05). 19% (51/261) smear-positive PTB, 26% (36/137) smear-negative PTB and 11% (10/94) of the extrapulmonary TB patients were HIV positive. The proportion of patients with extra-PTB varied from 11% to 38% across the centres and was hi

Outbreak of tuberculosis among homeless persons coinfected with human immunodeficiency virus.

We investigated a cluster of patients with tuberculosis (TB) in North Carolina and determined the extent of transmission of 1 strain of Mycobacterium tuberculosis. A retrospective cohort study was conducted. Homeless shelter attendance and medical records for 1999 and 2000 were reviewed. The period of exposure to M. tuberculosis was determined, and shelter residents were offered TB screening. DNA fingerprinting was performed on 72 M. tuberculosis isolates. In addition to the initial index cluster of 9 patients, another 16 patients were identified. Isolates of M. tuberculosis from all 25 patien

Herpes simplex and cytomegalovirus coinfected oral ulcers in HIV-positive patients.

Four HIV-positive patients with herpes simplex virus and cytomegalovirus coinfected oral ulcers are presented. All patients had persistent oral pain associated with nonhealing mucosal ulcers. Lesions occurred on the palate, retromolar pad, tongue, and lip, and the clinical appearance of the ulcers was nonspecific. Histologic and immunohistochemical stains showed herpes simples virus alterations in keratinocyte nuclei and cytomegalovirus alterations in mesenchymal/endothelial cell nuclei and cytoplasm. Lesions in one patient responded to ganciclovir therapy. One patient improved with acyclovir,

[Bacteremia due to Mycobacterium tuberculosis in patients coinfected with the human immunodeficiency virus].

BACKGROUND: Since the appearance of AIDS, bacteremia by Mycobacterium tuberculosis is an event described with ever greater frequency. The isolation of M. tuberculosis in blood cultures in patients coinfected by the human immunodeficiency virus and M. tuberculosis may vary the initial clinical diagnosis and confirm the picture as disseminated tuberculosis. METHODS: The clinical records of patients admitted to the General Penitentiary Hospital of Madrid with significant bacteremia during the study period (March 1, 1991-September 1992) were retrospectively and prospectively reviewed. Special att

Two coinfecting archaeal viruses provide insights into virus-virus interactions.

Virus-virus interactions can profoundly shape viral ecology and evolution, yet they remain poorly understood, particularly in haloarchaea. Upon characterization of a spindle-shaped virus, Tebenquiche spindle-shaped virus 1 (Tebi-SV1), isolated from Halorubrum strain TLS-6, we detected the presence of a second virus, Tebenquiche pleomorphic virus 1 (Tebi-PV1), that coinfects host cells. Gene sharing network analysis revealed several genomes related to Tebi-SV1 in public databases, most of which also co-occur with pleolipoviruses in their host genomes. Attempts to separate the two viruses were u

SARS-CoV-2 Coinfections and Severity in Hospitalized Children With Systematic Testing.

BACKGROUND: Co-circulation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with other respiratory viruses raised concerns that coinfections may increase pediatric coronavirus disease 2019 (COVID-19) severity, but evidence is limited by variable testing practices. We assessed the epidemiology and outcomes of SARS-CoV-2 respiratory viral coinfections in hospitalized children. METHODS: We analyzed national surveillance data from the Canadian Immunization Monitoring Program, ACTive (IMPACT) COVID-19 study. Children aged <17 years hospitalized with confirmed COVID-19 during Delta a…

Coinfection with malaria alters the fecundity and within-host persistence of an intestinal nematode.

Infections with soil transmitted helminths (STHs) are highly prevalent in humans living in the intertropical region. While, in most cases, STHs can establish chronic infections, the dynamics of the infection can be altered when other parasites exploit the same host. These changes can have consequences in terms of the health of the host, the epidemiology of the disease (e.g., the duration of the infection and the inter-host transmission success) and the fitness of the parasite. Here, we investigated if the coinfection with Plasmodium yoelii alters the dynamics (fecundity and with-host persisten…
