Diagnosis of a neonatal ophthalmic discharge, Ophthalmia neonatorum, in the molecular age: investigation for a correct therapy.

An early double case of acute Ophthalmia neonatorum in 3-day-old twins is reported. Culture of eye swabs showed a wide bacterial polymorphism, in which common bacteria, such as Klebsiella pneumoniae, Streptococcus pneumoniae, Corynebacterium ulcerans and other Enterobacteriaceae, coexisted with atypical Mycoplasmataceae and Chlamydiaceae from resident cervical-vaginal maternal microbiota. The neonates were in an apparently healthy state, but showed red eyes with abundant greenish-yellow secretion, mild chemosis and lid edema. The maternal cervical-vaginal ecosystem resulted differently positive to the same common cultivable, atypical bacteria culturally and molecularly determined. This suggested a direct maternal-foetal transmission or a further foetal contamination before birth. An extended culture analysis for common bacteria to atypical ones was decisive to describe the involvement of Mycoplasmas (M. hominis and U. urealyticum) within the scenario of the Ophthalmia neonatorum in a Caucasian couple. The introduction of a routine PCR molecular analysis for Chlamydiaceae and N. gonorrhoeae allowed to establish which of these were present at birth, and contributed to determine the correct laboratory diagnosis and to define an adequate therapeutic protocol obtaining a complete resolution after one year for culture and atypical bacteria controls. This study suggests to improve the quality of laboratory diagnosis as unavoidable support to a correct clinical diagnosis and therapy, in a standardized modality both for swabbing and scraping, to check the new-born microbial programming starting in uterus, overtaking the cultural age to the molecular age, and to revise the WHO guidelines of SAFE Strategy for trachoma eye disease, transforming it into SAFES Strategy where the S letter is the acronym of Sexual ecosystem and behavioural valuation/education.

Enigmatic question of early reactive arthritis disclosed after researches of mycoplasmas, Chlamydia trachomatis and enteropathogens following the holistic vision of human being.

An HLA-B27 genetic profile patient is fully investigated by molecular analyses after an anamnestic assessment of multi-site ecosystems, following the holistic vision of human being.VDRL and Widal-Wright (WWR) resulted positive, showing at Wright’s reaction a title of 1:40. Of all the enzymatic activities measured, only the ALP enzymatic pool activities showed a low increasing value of 297 U/L. Of all later acute phase proteins, Only C3 c protein value (127 mg/dL) and fibrinogen (376 mg/dL) were altered. Cultural and molecular oropharyngeal ecosystem investigation resulted significantly positive to Mycoplasmas(Mhand Uu) and Chlamydia trachomatis(Ct) together with a spread of saprophytic flora. From an accurate anamnesis, several and severe uro-genital clinical symptomatology emerged from birth until the beginning of rheumatologic symptomatologies that were confirmed by oldest Mh, Uu and Ctsilent chronic infections between these ecosystems. The molecular HPV research was negative, while the Thin prep pap-test was indicative of vaginosis and cellular reactive changes associated with inflammation. Parasitological research resulted positive for presence of 5-7 newly-formed G. lambliacysts for microscopic field, while digestibility test was positive for presence of several free fatty acid crystals. The remarkable presence of indigested meat fibre and several mucous dense filaments were observed. The pH value was 6.5, while blood faecal test was positive. The values observed were: ferritin 12 microg/L (10-120), total iron-binding capacity (TIBC) 310 &mgr;g/dL (300+-20), unsaturated iron-binding capacity (UIBC) 286 microg/dL (200-220) and iron seric level 24 microg/dL (60-130). Faecal research highlighted a very scarce presence of E. coli, resulting in 102 UFC/g of stool. Of all enteroinvasive pathogens, researched by molecular analyses, only Yersinia spp. was positive. After several specific cycles of antibiotic and antinflammatory therapies, the patient improved its general health condition considerably and showed almost complete regression of aching inguinal lymph node inflammation. In a picture of a worsening inflammatory process, produced by pathogens like Mycoplasmas, chronic silent or low grade inflammation atypical agents, in young HLA-B27 positive patient, VDRL test resulted positive. This value represents the first non-specific unique spy to reveal the precocious immunological signal in order to register the beginning of early innate immune system decay, keeping in mind that mycoplasmal and chlamydial infections are the triggering of cancer in patients genetically susceptible.

Can latent synergism of intestinal pathogens be responsible for inflammaging process causing Reiter's syndrome in a young patient HLA-B27 infected by atypical pathogens? A holistic view and clinical biochemical reinterpretation.

A case of a genetically HLA-B27 patient fully investigated by molecular analyses, following a holistic vision and an anamnestic assessment of multi-site ecosystems is repeated. VDRL, Lupus anti-coagulant (LAC) and Widal-Wright (WWR), resulted positive. The antibodies (IgG/IgA anti-Ct) against chronic Chlamydia trachomatis inflammation were positive. In the context of all the enzymatic activities in reference range, the AMS and the ALP enzymatic activities showed an increasing trend and a time course augment depending respectively. Cultures, parasitological, digestibility tests and molecular analyses were then performed to investigate the different human ecosystems. Parasitological research and digestibility test were performed, resulting a latent chronic bowel inflammation, including certain enteroinvasive pathogens, such as, Salmonella, Shigella, Yersinia and Campylobacter (Enteric Pathogens Group, EPG) and Escherichia Coli pathogens (Escherichia Coli Pathogens Group, ECPG). The Salmonella typhi-DNA resulted positive, while 90% of the total microbic charge (TMC) was represented by C. freundi in culture analyses. Interpreting the VDRL positive test as early triggering of autoimmune disease, a few acute phase proteins as a pauci-symptomatic chronic phlogistic process, the amylase and alkaline phosphatase alterations as tissue markers of early intestinal inflammation, the Widal's reaction positivity together with the precocious clinical and faecal manifestations, this study suggests the prime triggering role of these atypical pathogens to cause a chronic low grade autoimmune response against the tissue/organ susceptible target, causing inflammaging phenomenon in young patient with chronic latent infection by Salmonella typhi, leading to Reiter's syndrome, in HLA-B27 positive patient.

Jugulodigastric lymph node inflammation derived from chronic atypical oropharyngeal phlogosis recurring annually after flu virus vaccination: a holistic vision of a clinical case solved after chlamydicidal antibiotic therapy.

In this report, we evaluated the case history of a patient with longstanding chronic pharyngitis who had periodic clinical manifestation for three years after a flu vaccine administration, and after various treatments tried to resolve the chronic pharyngitis with unsuccessful antibiotic and anti-inflammatory therapies. The patient occasionally presented a slight ocular inflammation, while dysuria occurred after sexual activity. The search for common pathogens by use of pharyngeal swabs resulted only in Corynebacterium ulcerans growth. After this first result, we focused our investigations on ocular and uro-genital infections of Chlamydiaceae (Ct and Cp) and Mycoplasmataceae (Mh and Uu) families. We examined the patient?s pharynx using molecular and culture techniques from three different sites. Although several infectious agents, including viruses and bacteria, causing chronic pharyngitis are reported in the literature, these ocular and uro-genital pathogens are seldomly routinely investigated in the same patient in ORL. Furthermore, while episodes of chronic pharyngitis is one of the most common clinical manifestation in ENT patients, these atypical pharyngitis represent ever-increasing infections which must always be considered and researched by suitable instruments such as PCR. Only from the collection of detailed medical history and careful observations of clinical manifestation, indicative of an oral chronic pathologic phenomenon of low intensity initiated several years previously, starting with sudden outbreak and relapse like a bout of flu, we suggest to study these atypical infecting agents frequently localized in the urogenital human area, awhich would allow to highlight and to recognize these clinical cases that manifest themselves as chronic inflammation of jugulodigastric lymph nodes, remaining still unrecognized and rarely associated to chlamydial infection, confused with the response to flu vaccination. After several specific cycles of antibiotic therapy, the patient's health improved considerably and showed almost complete regression of jugulodigastric lymph node inflammation.

Ocular clinical pictures disclosed by PCR molecular diagnosis of Chlamydia trachomatis infection performed following the appropriate sampling modality in ocular ecosystem.

Four clinical cases regarding the correct diagnosis of early ocular Chlamydia trachomatis (Ct) inflammation, performed by two different modalities on the ocular ecosystem, are discussed. The present study was carried out in parallel using a cotton flock ocular swab and the scraping of upper lid conjunctiva. The ocular samplings were carried out by a first ocular swab from inner canthus and fornix, while the second by a conjunctival scraping from upper the conjunctiva of four patients. In the first case, by ocular swab, all samples resulted negative to Ct-DNA research by PCR, while the cultural analyses showed a growth of saprophytic and opportunist germs in all patients. No growth micetes resulted. On the contrary, in the second case, by conjunctival scraping, three of four samples were positive to Ct-DNA research. No fungal growth was observed, while only the 3rd patient, negative to Ct-DNA research, showed microbial growth. Our study, carried out with two different modalities of sampling on different areas of the same ecosystem, showed different results, demonstrating the importance of sampling accuracy for chlamydial research by molecular analysis in PCR, during the slight phase of inflammation. These initial data indicate that laboratory diagnosis by PCR for precocious Ct infection, not revealed clinically, could represent the first step for a correct diagnostic procedure, eliminating one of the critical points, allowing an accurate, effective and precocious antibiotic therapy. We hypothesize that only by following these correct procedures of sampling during the early phase of chlamydial inflammation, in the future, will it be possible to reduce a pejorative evolution of this worsening disease in people genetically susceptible, building a more efficacious Public Health program of prevention against chronic conjunctivitis and to favour a major prevention of trachoma in endemic areas.

Molecular approach by PCR is the best method to detect the presence of Chlamydia trachomatis and to define the true agent of ocular bacterial inflammation.

Chlamydia trachomatis (Ct) is an atypical agent for acute, subclinical and chronic conjunctivitis in developed countries, as stated by the International League against Trachoma. In order to evaluate the presence of Ct, from a total of 3,520 patients visiting the consulting room of the Eye Clinic of the University of Chieti, Italy from 2006-2008, we enrolled 171 patients affected by occasional mild, moderate or severe conjunctivitis in a three-arm prospective open study, using traditional analysis such as Immune Fluorescent Assay and Enzyme–Linked Fluorescent Assay (IFA and ELFA) and molecular analysis with Polymerase Chain Reaction (PCR) procedure for Ct DNA research (Ct DNA). At the same time, microbiological culture was carried out for common germs and mycetes. These patients were analyzed at different subsequent times. In the first arm (Group A) of 82 patients with IFA and ELFA only 10 people (12.2%) resulted positive to Ct infection with both methods. The presence of Ct was never alone, but always overlapped with contaminants, like corynebacteria, staphylococci, streptococci and colonbacteria, randomly distributed, while no growth of mycetes was observed. Of these positive patients, only one 47-year-old female, suffering from a moderate form of ocular chlamydial infection, showed serological conversion against this infection; furthermore, this female had also been suffering from reactive arthritis for sometime. In the second arm (Group B) of 89 patients, we carried out PCR for Ct detection: 82 (94.25%) were found positive to Ct – DNA research, with common germ growth randomly associated, without sex or age prevalence, as in group A; no mycetes were found. The third arm (Group C) included 37 negative patients from Group A with severe or moderate chronic conjunctivitis, randomly recruited between relapsing cases, with the addition of the single previously positive seroconversion case, for a total of 38 patients, who were re-evaluated by PCR Ct-DNA analysis. All these patients, negative to IFA and ELFA, were positive to Ct-DNA analysis. These data indicate a higher rate of Ct infection in patients with severe or moderate chronic conjunctivitis, resistant to usual therapies even after eradication of common germs, thus showing the advantage of introducing this molecular technique of analysis in mild to severe chronic or recurrent conjunctivitis.
