Focal infection: new age orancient history?THOMAS J. PALLASCH & MICHAEL J. WAHL

A focus of infection is a confined area that: (1) contains

pathogenic microorganisms, (2) can occur anywhere in

the body and (3) usually causes no clinical manifesta-

tions (1). A focal infection is a localized or generalized

infection caused by the dissemination of microorgan-

isms or toxic products from a focus of infection (1).

These concepts have led to the Focal Theory of

Infection (or Theory of Focal Infection) that postulates

a myriad of diseases caused by microorganisms

(bacteria, fungi, viruses) that arise endogenously from

a focus of infection. Some have expanded this to

include the environment via the concept of antigenic

(molecular) mimicry or even to the extent that all

diseases are caused by microbes (2, 3).Foci of infection have historically been postulated to

arise from the tonsils, adenoids, sinuses and oral cavity

with less common foci from the prostate, appendix, gall

bladder and kidney (4, 5). Oral foci have traditionally

been ascribed to pyorrhea alveolaris (periodontitis),

alveolar abscesses and cellulitis, pulpless teeth, apical

periodontitis, general oral sepsis and endodontically

treated teeth with viridans group streptococci (VGS)

being the principal metastatic microbial culprits (1, 4, 5).

Focal infections attributed to foci of infection have

included arthritis, neuritis, myalgias, nephritis, osteo-

myelitis, endocarditis, brain abscesses, prosthetic

joint infections, skin abscesses, pneumonia, asthma,

anemia, indigestion, gastritis, pancreatitis, colitis,

diabetes, emphysema, goiter, thyroiditis, Hodgkin’s

disease, fever of unknown origin, stupidity and

‘nervous diseases of all kinds’ (1, 6–8). Currently,

diseases postulated to be caused by microorganisms

include cancer (9), sarcoidosis, multiple sclerosis,

amyotrophic lateral sclerosis, autism, Guillain–Barre

syndrome, pediatric autoimmune neuropsychiatric

disorders associated with streptococcal infections

(PANDAS), Tourette’s syndrome, myasthenia

gravis, polycystic kidney disease, obesity, Alzheimer’s

disease, diabetes mellitus and, of particular interest to

dentistry, cardiovascular disease (4, 10). Many of these

are proposed to affect the host by antigenic mimicry:

microbial antigens similar to host antigens that induce

an immune response that damages host tissue (11).

The classic pathway of focal infection is by direct spread

via blood or lymphatic metastasis of the infecting

microorganism, its toxic products or tissue-damaging

immunologic reactions to the microorganism.

Several characteristics consistently appear through-

out the long history of focal infection: (1) theories of

disease espoused by authoritative (some might say

autocratic) individuals with little or no science to

support their theses (doctrine without data), (2)

consistent application of focal infection to diseases for

which medicine has no good concepts of etiology and/

or treatment, (3) consistent and pervasive extrapola-

tion beyond the data and (4) a common disregard for

the accepted methodology of science (i.e. controlled

studies). Often, the ‘disregard syndrome’ is apparent:

the unintentional failure to cite previous scientific

works, scorn for previous sound published data that is

not considered ‘cutting edge’, apparently intentional

disregard for already published data that does not

conform or even contradicts the position espoused by

the investigator or an unintentional lack of regard for

relevant literature due to ignorance of the field being

investigated (12). ‘Reverse Investigation’ is not un-

common: start with the conclusion and then gather

only the facts that support it. The tendency to

programmed conferences is common: only those who

are of the samemind are invited and commonly leads to

what Jane’s Defense Weekly terms ‘incestuous ampli-

fication’: a condition in warfare where one only listens

Research Reports: Biological

IntroductionThe association between dysbiosis of the oral microbiome and periodontitis is now well established (Mira et al. 2017). Although there are significant individual-to-individual varia-tions in the microbial composition of subgingival biofilms in health (Hall et al. 2017), the development of disease coincides with a characteristic population shift. Consistently, the change involves not only an increase in the overall microbial biomass but also the emergence of bacterial species that are only pres-ent in low abundance in health and a proportionate decrease in the abundance of others (Marsh 1994; Socransky et al. 1998; Diaz et al. 2016). Although culture-based studies originally indicated that the emergent bacterial populations in the disease-associated communities may represent only a relatively small number of different taxa (Socransky et al. 1998; Holt and Ebersole 2005), the application of more advanced technologies has demonstrated that a wider range of organisms should be considered (Griffen et al. 2012; Abusleme et al. 2013). This, in turn, has led to the concept of a community-wide perturbation in the composition of the microbiome associated with peri-odontal disease (Hajishengallis and Lamont 2012; Curtis 2014). However, it remains controversial to what extent the

observed shift in the microbial population structure in peri-odontitis is the primary cause of pathology or simply a conse-quence of the altered environmental conditions induced in an inflammatory disease.

In previous studies, using a mouse model of periodontal dis-ease, we demonstrated that the introduction of Porphyromonas gingivalis into the oral microbiome of specific pathogen-free (SPF) mice led to significant alterations in both the quantity

Horizontal and Vertical Transfer of Oral Microbial Dysbiosis and Periodontal Disease

M.A. Payne1, A. Hashim2, A. Alsam1, S. Joseph3, J. Aduse-Opoku3, W. Wade3,4, and M.A. Curtis3

AbstractOne of the hallmark features of destructive periodontal disease, well documented over the last 50 y, is a change to the quantitative and qualitative composition of the associated microbiology. These alterations are now generally viewed as transformational shifts of the microbial populations associated with health leading to the emergence of bacterial species, which are only present in low abundance in health and a proportionate decrease in the abundance of others. The role of this dysbiosis of the health associated microbiota in the development of disease remains controversial: is this altered microbiology the driving agent of disease or merely a consequence of the altered environmental conditions that invariably accompany destructive disease? In this work, we aimed to address this controversy through controlled transmission experiments in the mouse in which a dysbiotic oral microbiome was transferred either horizontally or vertically into healthy recipient mice. The results of these murine studies demonstrate conclusively that natural transfer of the dysbiotic oral microbiome from a periodontally diseased individual into a healthy individual will lead to establishment of the dysbiotic community in the recipient and concomitant transmission of the disease phenotype. The inherent resilience of the dysbiotic microbial community structure in diseased animals was further demonstrated by analysis of the effects of antibiotic therapy on periodontally diseased mice. Although antibiotic treatment led to a reversal of dysbiosis of the oral microbiome, in terms of both microbial load and community structure, dysbiosis of the microbiome was reestablished following cessation of therapy. Collectively, these data suggest that an oral dysbiotic microbial community structure is stable to transfer and can act in a similar manner to a conventional transmissible infectious disease agent with concomitant effects on pathology. These findings have implications to our understanding of the role of microbial dysbiosis in the development and progression of human periodontal disease.

Kriterien: • Risiko für Herderkrankung

• Risikofaktoren für die zahnärztliche Therapie zu diesem bzw. zu

einem späteren Zeitpunkt

• Management von potentiell auftretenden Komplikationen

• Zeitfenster / Dringlichkeit

Herdsanierung – Gruppen - KriterienNiedriges Risiko

§ Meist ausreichend Zeit zur adäquaten zahnärztlichen Therapie

§ Zahnärztliche Maßnahmen können auch nach der geplanten OP unter Befolgung spezieller Richtlinien durchgeführt werden (Gerinnungskontrolle, AB-Abdeckung)

Mittleres Risiko

§ Möglichst konservatives und zahnerhaltendes Vorgehen bei strengerer Indikationsstellung

§ u.U. bereits bestehende Risikosituation à adaptiertes Vorgehen (Gerinnungseinstellung, AB-Abdeckung 24h prä- und 7 Tage postoperativ, primär plast. Wundverschluss )

§ Die Sanierung sollte mind. 2 Wochen vor der geplanten OP/Therapie abgeschlossen sein

Hohes Risiko

§ Radikales Vorgehen mit strenger Indikationsstellung

§ Häufig wenig Zeit

§ u.U. bereits bestehende Risikosituationà adaptiertes Vorgehen (Gerinnungseinstellung, AB-Abdeckung 24h prä- und 7 Tage postoperativ, primär plast. Wundverschluss )

Häufige Probleme bei der Herdsanierung

■ Häufig multimorbide Patienten

■ Enges Zeitfenster

■ evtl. großer Sanierungsbedarf

■ u.U. nach Zahnextraktionen begrenzte Möglichkeiten zur prothetischen Rehabilitation nach erfolgter

Therapie der Grunderkrankung (antiresorptive Therapie, Strahlentherapie)

■ Prognose quoad vitam? – Abwägung von Nutzen-Risiko in Hinsicht auf die Lebensqualität des

Patienten

■ wenig wissenschaftliche Evidenz
