The age old view of seeing modern medicine as being scientifically up-to-date is rapidly fading away. More and more people are falling outside of medicine’s ability to care for them and seeking help elsewhere. Nowhere is this more evident than with systemic fungal candida. Medical doctors don’t acknowledge its existence, except in severely immunosuppressed patients as those with AIDS, some cancers, and patients taking drugs to suppress the immune system.
Science has published over 62,000 studies about candida since the introduction of antibiotics in the mid-1940s, with scientists weighing in on its effects in all types of individuals, including those with healthy immune systems. Obviously, there is a huge gap between science and medicine when it comes to candida.
While medical doctors continue to insist that candida only affects the immunosuppressed, scientists and researchers state otherwise, and extend the list of those affected to include: diabetics, premature infants, surgical patients (4)(5)(6); hospitalized patients, especially in Intensive Care Units, or having major injuries, burn victims (5); nutritional deficiencies, dentures, salivary abnormalities (7); as well as aging (7)(8)(9)(10); stress (2); Alcoholism, cirrhosis, tuberculosis, intravenous drug abuse, and granulocytopenia (6).
Researchers continuously broaden the scope of those being affected. Valdimarsson et al. state that there are no common immunological denominators (1). Senet states that the pathogenic behavior of Candida may appear following even a slight modification of the host (2). Berg et al. on behalf of Biocodex Pharmaceuticals states that Candida spreads in immunocompetent individuals (3).
Medical doctors state that candida only causes problems in immunosuppressed individuals, yet there are over 100 symptoms, conditions, and diseases that can be caused by or modulated by candida. The common factor in all of these is not immunosuppression, but inflammation. Candida causes an increase in Matrix Metalloproteases (MMPs) and a decrease in inhibitors of MMPs that can lead to Lupus, Scleroderma, Glaucoma, Cirrhosis, Fibrosis, Tumors, Dementia, Aortic Aneurysms, Arthritis, Psoriasis, Multiple Sclerosis, Rheumatism, Crohn’s, and autoimmune conditions and syndromes (11)(12)(13).
Given that fungal candida is associated with so many symptoms, conditions, and diseases, one would think that a medical doctor would be aware of well-documented, evidence-based, scientifically-backed research that demonstrates time and time again a common causative agent. Once this cause was known, it would serve the best interests of the patient to be aware of and avoid when possible, the use of any predisposing factors that would create such a cause. If for some reason this was unavoidable, then the doctor should provide the patient with this information and then instruct them on how to compensate and remedy any imbalances caused by it. This however, as far as candida is concerned, does not happen in medicine today. If it did, medical doctors would be acutely aware that antibiotics cause systemic fungal conditions whenever they are used, and that this can then then lead to other conditions and diseases. Upon giving antibiotics, they would recommend that the patient follow protocols that can help to correct and remedy the effects of antibiotics in the body.
The widespread use of antibiotics, which induce neutropenia, an abnormally low number of neutrophils (white blood cells), and immune system suppression is commonly attributed by science to be the most consistent cause of systemic Candida (14)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(7)(2)(26)(27)(28)(29)(3)(30)(32)(33). Corticosteroids suppress immune system function and can lead to fungal candida (34)(21)(3). Intestinal homeostasis is critical for human health (15)(4)(2)(27)(3)(31). This is just a sampling of what’s documented, but medicine acknowledges none of it in the practice of medicine.
The science of candida and how it affects the body goes far beyond what is written here. The ability of antibiotics to create systemic fungal candida is documented in thousands of studies dating back to the introduction of antibiotics in the 1940s. This gap between science and the practice of modern medicine is a major cause of sickness and illness today. In truth, it cannot be referred to as a gap, for it is a wide chasm that millions of people fall into while under modern medical care. As modern medicine continues its decline, patients will search for the truths that lead them back to a state of health and a life of vitality.

1. Immunological phenomena associated with chronic mucocutaneous candidiasis have recently been intensively studied by many workers (reviewed by Kirkpatrick, Rich & Bennett, 1971). The results have shown that there is no common immunological denominator in this disease. The most common finding, however, is defective cellular immunity, which may or may not be accompanied by failure of in vitro lymphocyte transformation.

2. Clinical studies show that any modification of the host immune status can facilitate the proliferation of endogenous Candida which, according to the importance of the immune deficiency, can provoke diseases ranging from benign localized mucocutaneous candidosis to sometimes lethal systemic invasions. The pathogenic behavior of Candida cells is mainly due to a very high phenotypic biodiversity. Following even very slight environmental modifications, it may change its behavior through the appearance of new or amplified such as tube formation, adherence, protease secretion, etc. Together with the impairment of host defenses, these new invasive properties lead to the so-called opportunistic pathogenicity of Candida cells. From a host point of view, after the integrity of surface teguments, the mucosal protection is ensured by the Th1 “cellular” immune response which, through pro-inflammatory cytokine production, boosts the efficacy of the phagocytes (Polymorphonuclear cells and macrophages). Neutrophils are of particular importance as deep seated Candida proliferation is mostly associated with neutropenia. Whatever the pathogenic process, it is mostly due to modifications provoked by increasing medical awareness which makes patients more susceptible to illness. A better knowledge of the precise mechanisms involved and would lead to improved strategies for prevention.
Stress is an often forgotten cause of temporary immunodeficiency. Neuroendocrine regulation and chronobiological effects may notably modulate the immune system and provide the opportunity of fungal proliferation.
As Wilson (1962) put it: “C. albicans is a better clinician and can discover abnormalities in persons much earlier in the course of the development of such abnormalities than we can with our chemical tests”.
The pathogenic behaviour of Candida may appear following even a slight modification of the host.
Risk factors and physiopathology of Candidiasis
3. We previously reported that the primary defense mechanisms inhibiting translocation from the GI tract are an ecologically balanced GI microflora (preventing intestinal microbial overgrowth or colonization by exogenous microorganisms, or both), the host immune defense system, and the physical barrier of an intact intestinal mucosa. Oral antibiotics are especially effective in disrupting the GI ecologic equilibrium, leading to intestinal overgrowth by certain normal flora bacteria and their subsequent translocation from the GI tract.
All mice were given streptomycin and penicillin ad libitum for 4 days (0-4) in drinking water to reduce their indigenous GI microflora.
Prednisolone immunosuppression increased the mean numbers of C albicans translocating to the MLN (mesenteric lymph node) from 775 to 9336 C albicans/g MLN.
Also, placing fresh C albicans in the drinking water each day was as effective a method of colonizing mice with the organism as was daily intragastric inoculation of C albicans.
Viable C albicans translocated across the GI mucosal barrier to the MLN in immunocompetent, antibiotic-decontaminated mice colonized with C albicans, but the translocating C albicans did not spread systemically from the MLN to other organs. S. boulardii treatment reduced the incidence of MLN positive for C albicans in these immunocompetent mice but did not reduce the mean numbers of C albicans per gram of MLN. The ileal and cecal populations of C albicans were not decreased whether S. boulardii was given prior to or following C albicans challenge.
Disruption of the intestinal microecology by oral antibiotics to cause intestinal microbial overgrowth and increased microbial translocation is clinically relevant since antibiotic therapy also predisposes humans to intestinal microbial overgrowth and infection by various bacteria and yeasts, such as C albicans.
Oral antibiotic therapy in humans often leads to colonization and over-growth of the GI tract by C. albicans (Stone HH, Geheber CE, Kolb LD, Kitchens WR. Alimentary tract colonization by Candida albicans. J Surg Res 1973;14:273-6.)

4. Candida albicans is a component of the normal flora of the alimentary tract and also is found on the mucocutaneous membranes of the healthy host. However, when immune defenses are compromised or the normal microflora balance is disrupted, Candida transforms itself into an opportunistic pathogenic killer. Candida is the leading cause of invasive fungal disease in premature infants, diabetics, and surgical patients, and of oropharyngeal disease in AIDS patients. As the induction of cell-mediated immunity to Candida is of critical importance in host defense, we sought to determine whether human dendritic cells (DC) could phagocytose and degrade Candida and subsequently present Candida antigens to T cells. Immature DC obtained by culture of human monocytes in the presence of granulocyte-macrophage colony-stimulating factor and interleukin-4 phagocytosed unopsonized Candida in a time-dependent manner, and phagocytosis was not enhanced by opsonization of Candida by the mannose-fucose receptor. Upon ingestion, DC killed Candida as efficiently as human M, and fungicidal activity was not enhanced by the presence of fresh serum. Although phagocytosis of Candida by DC stimulated the production of superoxide anion, inhibitors of the respiratory burst (or NO production) did not inhibit killing of Candida, even when phagocytosis was blocked by preincubation of DC with cytochalasin D. Further, although apparently only modest phagolysosomal fusion occurred upon DC phagocytosis of Candida, killing of Candida under anaerobic conditions was almost equivalent to killing under aerobic conditions. Finally, DC stimulated Candida-specific lymphocyte proliferation in a concentration-dependent manner after phagocytosis of both viable and heat-killed Candida cells. These data suggest that, in vivo, such interactions between DC and C. albicans may facilitate the induction of cell-mediated immunity. in serum. Like macrophages (M), DC recognized
Despite appropriate therapy, mortality from systemic Candida infections in immunocompromised individuals is nearly 30%. In human immunodeficiency virus-infected individuals who have not yet developed advanced immunodeficiency, the prevalence of oropharyngeal Candida is from 7 to 48% of patients. As the immunodeficiency in AIDS patients progresses, the prevalence of oral candidiasis increases to 43 to 93%. Furthermore, the development of oral candidiasis in the early stages of human immunodeficiency virus infection is highly predictive of worsening immunodeficiency.

5. A new study has uncovered the genetic wiring diagram underlying the infectiousness of Candida albicans, a fungus that causes thrush in babies, vaginal infections in women, and life-threatening infections in chemotherapy and AIDS patients. The study, led by Dr. Gerald R. Fink, Director of the Whitehead Institute for Biomedical Research, reveals that one key to Candida’s infectiousness lies in its ability to switch from a rounded form to filamentous forms. Fungal infections in hospitalized patients have almost doubled throughout the 1980s, often with life-threatening results in individuals with weakened immune systems. Candida, in particular, poses a serious threat and is associated with high mortality rates in patients undergoing chemotherapy. Candida is also a major cause of infection in hospitalized patients, especially those in Intensive Care Units, patients after major injuries or surgery, patients with burns, and premature babies.
In this study, Dr. Fink and his colleagues used molecular biology techniques to identify the components of the filamentation circuit in yeast. With the recently completed yeast genome to guide them, the scientists began to knock out suspicious genes and, by a process of elimination, discovered the culprits that are responsible for filamentation. Once scientists identified the key yeast filamentation genes, they simply plucked out the analogous genes in Candida. “Candida albicans is three hundred million years apart evolutionarily from yeast-as far away in evolution as humans are from turtles-and yet, the basic logic circuit was conserved,” says Dr. Fink.

6. Although healthy subjects may host fungal diseases, various predisposing factors that depress the immune system have been implicated in most patients developing fungal infections or fungal arthritis, or both. Alcoholism, cirrhosis, diabetes, tuberculosis, cancer, prematurity, treatment with corticosteroids, cytotoxic drugs, prolonged use of intravenous antibiotics, intravenous drug abuse, granulocytopenia, and marrow hyperplasia are among the predisposing factors. Neonates are the first group of patients in whom haematogenously originated Candida arthritis can occur. The illness is a hospital acquired disease of sick children with underlying diseases such as the respiratory distress syndrome, and gastrointestinal defects. C albicans, which is responsible for more than 80% of the reported cases, and C tropicalis are the species responsible for this disease. Arthritis is usually present with accompanying metaphysial osteomyelitis. Bone infection might originate from the infected synovium or via the metaphysical vessels. Polyarthritis occurs in most patients and the knee is the joint most often affected.
Arthritis originated by haematogenous dissemination beyond the neonatal period is usually a complication of disseminated candidiasis in patients with serious underlying disorders or intravenous drug abusers. C albicans is again the causative organism in about 80% of cases, and C tropicalis is responsible for most of the remaining cases. Two distinct clinical presentations can be observed: (a) acute onset of constitutional and synovial symptoms (about two thirds ofpatients), with the aetiological diagnosis established within the first week, and (b) indolent presentation, with mild systemic and arthritic symptoms, and delay in the diagnosis for months or years.

7. With the increasing number of immune compromised patients, fungi have emerged as major causes of human disease. Risk factors for systemic candidiasis include presence of intravascular catheters, receipt of broad-spectrum antibiotics, injury to the gastrointestinal mucosa and neutropenia. Within a species, the fungal morphotype (e.g. yeast, pseudohyphae and hyphae of Candida albicans) may be an important determinant of the host response. Whereas yeasts and spores are often effectively phagocytosed, the larger size of hyphae precludes effective ingestion.
Differentiation of CD4+ T cells along a T-helper (Th) cell type 1 (Th1) or type 2 (Th2) pathway and development of specific Th responses, is an essential determinant of the host’s susceptibility or resistance to invasive fungal infections. Development of Th1 responses is influenced by the concerted action of cytokines, such as interferon (INF)-c, interleukin (IL)-6, tumour necrosis factor (TNF)-a, and IL-12, in the relative absence of Th2 cytokines, such as IL-4 and IL-10 (Romani, 2002).
Oropharyngeal candidiasis (OPC) is among the most common mycotic infections of immunocompromised patients. Development of infection depends upon both systemic and local determinants. Risk factors for oral candidiasis include extremes in age, diabetes mellitus, particularly when glycemic control is poor, nutritional deficiencies, use of broad spectrum antibiotics and immunosuppression (especially of cell-mediated immunity) (Klein et al., 1984; Guggenheimer et al., 2000). Local factors that promote infection include dentures, salivary abnormalities, treatment with inhaled steroids, and destruction of mucosal barriers with radiotherapy for head and neck cancers or cytotoxic chemotherapy. Human immunodeficiency virus (HIV) is one of the most important predisposing conditions worldwide. AIDS patients have a particularly high incidence of mucosal candidiasis, which is often recurrent and, when it involves the esophagus, can be disabling (Sangeorzan et al., 1994). Local defence mechanisms against mucosal infection include salivary proteins, such as lactoferrin, beta-defensins, histatins, lysozyme, transferrin, lactoperoxidase, mucins, and secretory immunoglobulin A. These impair adhesion and growth of Candida in the oropharyngeal cavity. Development of OPC has been associated with a salivary Th2-type cytokine profile (Leigh et al., 1998).
Cell-mediated immunity plays the dominant role in prevention of candidiasis at the gastrointestinal surfaces. In AIDS, development of oropharyngeal and oesophageal candidiasis correlates with declining CD4+ lymphocyte counts. OPC is also associated with T cell immunosuppression from corticosteroid therapy, organ transplantation, cancer chemotherapy and chronic mucocutaneous candidiasis (CMC). Candida species have emerged as an important cause of bloodstream and deep tissue infections. Risk factors for Candidaemia include breakdown of mucosal barriers due to cytotoxic chemotherapy and surgical procedures, neutropenia, changes in the gut flora due to antibiotics, and invasive interventions that breach the skin, such as intravenous lines and drains (Wey et al., 1989). Common sites of dissemination include the bloodstream, kidney, liver, spleen, and endovascular structures. Quantitative and qualitative abnormalities of neutrophils and monocytes are associated with systemic candidiasis. Patients with lymphoma, leukaemia, chronic granulomatous disease, and recipients of intensive cancer chemotherapy with resultant neutropenia are at increased risk for disseminated infection. Similar to the situation with Aspergillus hyphae, the large size of Candida hyphae and pseudohyphae may preclude phagocytosis. Achieving a balance between Th1 and Th2 cytokines may be important for optimal antifungal protection while minimizing immune-mediated damage. In vivo models indicate that T regulatory cells attenuate Th1 antifungal responses, induce tolerance to the fungus and participate in the development of long lasting protective immunity after yeast priming (Montagnoli et al., 2002; Romani, 2004).
Dendritic cells play an important role in linking innate with adaptive immunity. Dendritic cells that ingest the yeast form induce differentiation of CD4+ T cells toward a Th1 pathway. In contrast, hyphae induce Th2 responses (d’Ostiani et al., 2000). Neutrophils, macrophages and natural killer (NK) cells also modulate adaptive responses to the fungus. Neutrophils differentially induce Th1 and Th2 responses depending on whether the exposure is to yeast or hyphae.
The syndrome of chronic disseminated candidiasis (CDC, also known as hepatosplenic candidiasis) predominantly affects patients with haematological malignancies upon recovery from neutropenia. CDC is characterized by increased serum levels of IL-10 and local production of Th2-inducing cytokines by hepatocytes and by infected mononuclear cells (Roilides et al., 1998b; Letterio et al., 2001). Thus, although neutropenia is a major predisposing factor, the propensity for persistence of the fungus in infected tissues may be a consequence of cell-mediated immune dysregulation with suppression of Th1 and overexpression of Th2 responses.

8. The study indicates that host age is a determining factor in yeast carriage. From the neonatal period, humans go through several dentition periods, and the emergence and substitution of teeth and changes in living habits greatly change the environment of the oral cavity, and therefore influence colonization by oral commensal organisms, certainly.
including Candida spp. Russell and Lay showed that the frequency of oral yeast carriage at birth was low, doubled by the time that infants were discharged from the hospital at about seven-day old, and increased sharply after one month old. Kleinegger et al. demonstrated that the frequency of oral yeast carriage was 44% of the examined individuals in a group aged from 0.5 to 1.5, 24% in a 5-7-year-old group, 40% in a 15- to 18-year-old group.
In a review by Odd in 1988, the highest reported frequencies were 71% of school children in the United Kingdom, and 56% of children in Israel. Different sampling and identification methods for Candida spp. would also certainly influence the results. Because of the uneven distribution of C. albicans throughout the oral cavity, swab samples can yield false-negative culture more often than oral rinse samples or imprint culture. The number of false-negative cultures was reduced by the swabbing of two sitesrather than one. In conclusion, our observations indicate that there is an increased risk of dental caries with C. albicans carriage rates in preschool and school children.

9. The prevalence of opportunistic fungal infections has increased dramatically among the aged population in recent years. Thiswork investigated the effect of ageing on murine defenses against Candida albicans. Aged C57BL/6 mice that were experimentallyinfected intravenously had a significantly impaired survivaland a higher tissue fungal burden compared with young mice.In vitro production of tumour necrosis factor (TNF)- by macrophagesfrom aged mice in response to yeast cells and hyphae of C. albicanswas significantly lower than production by macrophages fromyoung mice. In vitro production of cytokines, such as TNF- andgamma interferon (IFN-), by antigen-stimulated splenocytes frommice intravenously infected with C. albicans cells was alsodiminished in old mice. This decrease in production of T helper1 cytokines in old mice correlated with a diminished frequencyof IFN–producing CD4+ T lymphocytes, although the ability todevelop an acquired resistance upon vaccination (primary sublethalinfection) of mice with the low-virulence PCA2 strain was notaffected in aged mice. The diversity of antigens recognizedby C. albicans-specific antibodies in sera from infected agedmice was clearly diminished when compared with that from infected young mice. Taken together, these data show that aged mice developan altered innate and adaptive immune response to C. albicans and are more susceptible to systemic primary candidiasis.

10. Previous work by our group showed that aged C57BL/6 mice develop an altered innate and adaptive immune response to Candida albicans and are more susceptible to systemic primary candidiasis. In this work, we used young (2-3 months old) and aged (18-20 months old) C57BL/6 mice to study in vitro the influence of aging on (1) the fungicidal activity of neutrophils and macrophages, (2) the production of cytokines by resident peritoneal macrophages in response to C. albicans, and (3) cell surface Toll-like receptor (TLR) 2 expression on resident peritoneal macrophages. Our results indicate that murine phagocytes have a fungicidal activity well preserved with aging. In vitro production of proinflammatory cytokines (IL-6, IL-1beta, and tumor necrosis factor-alpha and chemokines (MIP-2) by purified (CD11b(+)) peritoneal macrophages in response to yeasts and hyphae of C. albicans was significantly lower in aged mice as compared with young mice. However, the production of IL-10 by macrophages, in response to C. albicans, was similar in both young and aged animals. Moreover, baseline TLR2 surface expression level was lower on aged macrophages than on control macrophages. Taken together, these data indicate that the increased susceptibility to C. albicans disseminated infections in aged mice is correlated with defects in TLR2 expression and in cytokine production, but not with an impaired fungicidal activity.

11. A variety of morphological changes in the basement membrane (BM) are known to occur in inflammatory diseases. Modifications of the BM can be associated with significant changes in protein content. Candida albicans (C. albicans) is normally a commensal organism and is a member of the natural flora of a large number of healthy individuals. However, under certain conditions, C. albicans can invade host tissues, causing inflammation and tissue damage. The aim of this study was to investigate the effect of C. albicans on the expression and production of structural (laminin-5 and type IV collagen) and inflammatory
