Mycobacterium avium Paratuberculosis (MAP) and Cytomegalovirus (CMV) Are Frequently Detected in the Saliva of Patients Recently Diagnosed with Crohn Disease (CD) Whereas Oral Propionibacterium Acnes (PA) or Methylacetate (MA) in Their Breath Is Rare  [PDF]

Journal of Biosciences and Medicines (JBM) , 2015, DOI: 10.4236/jbm.2015.312003
Abstract:

We investigated the presence of MAP, CMV, or Epstein-Barr virus (EBV) in the saliva of patients presenting with periodontal disease, gingivitis or oral aphthosis. We also measured methylacetate in their breath and looked for the presence of PA on their tongue. All patients were prospectively enrolled into a two-year cohort study. We compared the group presenting with CD versus the group without CD. 167 patients were enrolled. 24 patients presented with CD. CMV and MAP were found concomitantly in 67% of CD patients (17 patients) whereas only 1 patient (<0.1%; p < 0.001) has these infectious agents in the comparative group. PA was rare in CD (25% versus 70.6%; p < 0.001). MA was low, especially with an empty stomach (0.59 ppm +/? 1.45 versus 5.14 ppm +/? 8.97; p < 0.001). It was concluded that the association MAP + CMV was frequently found in oral lesions of CD at an early stage. Detection of PA, MAP and CMV, as well as breath test could be easily performed and may participate to the early diagnosis of CD.

Abstract:
Cytomegalovirus (CMV) is an important pathogen in immunocompromised individuals. Coupled with Human Immunodeficiency Virus (HIV), it causes end organ diseases leading to increased morbidity and mortality in the population. The prevalence of Cytomegalovirus infection is above 93% in HIV infected children in Kenya. Despite, a high Cytomegalovirus seroprevalence found in children, few studies have documented CMV in adults. This study was done to determine the seroprevalence of CMV infection and its associated risk factors among HIV patients attending Thika level 5 Hospital in Kiambu County, Kenya. The study also evaluated the effect CMV infection on the immunity of HIV infected patients. A cross-sectional study involving 163 HIV positive participants from different age groups was carried out. A questionnaire was used to assess the socio-demographic and specific risk factors associated with cytomegalovirus. Blood was collected and analyzed for CD4 counts, CMV IgG and IgM. The seroprevalence of CMV was found to be 89% (CMV IgG) while the incidence was 10.4% (CMV IgM). The study found that CMV infection leads to more suppression of the immunity among the HIV infected patients. In addition, education, economic status, having other sexual transmitted infections, sharing drinks, immune status and blood transfusion were associated with CMV infection (p < 0.05). The study recommends adoption of CMV screening services and education on CMV risk factors as CMV infection preventive strategies.

Abstract: objective: to determine the prevalence of congenital cytomegalovirus infection in newborn infants included in the neonatal screening program coordinated by the state health services in san luis potosí. material and methods: we evaluated the presence of cytomegalovirus in blood samples stored in filter paper. results: cytomegalovirus was detected in 10 (0.68%) of the 1 457 samples included in the study. there were no differences in the characteristics of infants with congenital infection compared to those without infection. conclusions: it is necessary to increase awareness of health professionals regarding the prevalence and impact of congenital cytomegalovirus infection.
The Natural Selection of Herpesviruses and Virus-Specific NK Cell Receptors
Joseph C. Sun,Lewis L. Lanier
Viruses , 2009, DOI: 10.3390/v1030362
Abstract: During the co-evolution of cytomegalovirus (CMV) and natural killer (NK) cells, each has evolved specific tactics in an attempt to prevail. CMV has evolved multiple immune evasion mechanisms to avoid detection by NK cells and other immune cells, leading to chronic infection. Meanwhile, the host has evolved virus-specific receptors to counter these evasion strategies. The natural selection of viral genes and host receptors allows us to observe a unique molecular example of "survival of the fittest", as virus and immune cells try to out-maneuver one another or for the virus to achieve détente for optimal dissemination in the population.
Síndrome de opsoclonus-mioclonus-ataxia (OMA) parainfeccioso secundario a infección por citomegalovirus
Zarco,Luis; Gil,Laura; Millán,Sonia Patricia; Pretelt,Felipe;
Acta Neurológica Colombiana , 2011,
Abstract: this paper reported a 66 years old patient, with eye movements alteration associated to myoclonus, cerebellar ataxia and dysarthria, secondary to a parainfectious process by cytomegalovirus. the physiopathology of the opsoclonus myoclonus ataxia syndrome, its etiologies and the available therapeutic options were checked, and turned out that it is not very common since only one previous published case associated to cytomegalovirus was found.

Abstract: we report a case of a male 49 years old, without clinical history, excepting rape in 1996, that was admitted to the emergency room of hgugm because of diarrhea 6 months duration, plus fever (39oc) in the last 2 months. he was diagnosed of infection by the human immunodeficiency virus (hiv), with serum antigenemia (70cells), and colonic biopsy positives for cytomegalovirus, and a normal colonoscopy. cytomegalovirus colitis is the major etiologic infectious agent in patients with aids-associated diarrhea, although it can be the diagnostic index for aids in a few cases.
Celulitis por citomegalovirus

Medicina (Buenos Aires) , 2002,
Abstract: cutaneous lesions in cmv infection are rare, often a late manifestation of systemic infection, and usually herald a fatal course. a 70 year-old woman received a kidney transplantation one month before consulting and immunosuppressive therapy that included cyclosporine a and methylprednisone. she complained of fever, local pain in her right leg, and an erythematous and swelling plaque. she was treated with intravenous antibiotics without improvement. a skin biopsy was performed and the tissue obtained was sent for bacterial and fungal cultures as well as for histological examination. cultures were negative. the biopsy showed cmv cytopathic changes. immunoperoxidase staining was positive for cmv and polymerase chain reaction (pcr) testing revealed cmv dna. she was treated with ganciclovir with resolution of the lesion. cmv cellulitis is a rare cutaneous manifestation which has not been previously reported.

Abstract: we retrospectively evaluated 73 immunocompetent adult patients assisted at our infectious diseases clinic between march 1999 and march 2004 who presented fever and asthenia, mild to moderate increase of transaminases and serological findings compatible with recent cytomegalovirus infection. we excluded patients with a history of transfusions, drug abuse, immunodeficiencies, preexistent hepatic impairment or serological findings compatible with acute hepatitis a, b and c (hav, hbv, hcv) and epstein barr virus (ebv). the laboratory diagnosis of recent cytomegalovirus infection was made by especific igm detection (elisa) or a significant increase of specific igg. the most frequent symptoms were fever (85%) and asthenia (83%), followed by cephalea (25%), splenomegaly (20%), adenomegalies (22%), pharyngitis (25%), myalgias (25%) and hepatomegaly (19%). all the patients showed moderate increase of transaminases and lymphomonocytosis (73/73). in average, alt was increased by 6 fold and ast by 3.5 fold. the clinical characteristics that differentiate cmv infection from epstein-barr infection are the lesser frequency of adenomegalies and pharyngitis in the former. the differential diagnosis of cmv infection with hepatic involvement from acute hepatitis a and b, is based on the absence of jaundice, the lower elevation of transaminases, the intense lymphomonocytosis and the presence of specific igm against cmv that are characteristic of cmv infection. in conclusion, in previously healthy young adults with fever, intense asthenia, lymphomonocytosis and moderate increase in transaminases levels, cytomegalovirus infection should be investigated.
