Medicine:Infections associated with diseases

From HandWiki

Infections associated with diseases are those infections that are associated with possible infectious etiologies that meet the requirements of Koch's postulates. Other methods of causation are described by the Bradford Hill criteria and evidence-based medicine. Koch's postulates have been modified by some epidemiologists, based on the sequence-based detection of distinctive pathogenic nucleic acid sequences in tissue samples. When using this method, absolute statements regarding causation are not always possible. Higher amounts of distinctive pathogenic nucleic acid sequences should be in those exhibiting disease, compared to controls. In addition, the DNA load should become lower with the resolution of the disease. The distinctive pathogenic nucleic acid sequences load should also increase upon recurrence.

Other conditions are met to establish cause or association including studies in disease transmission. This means that there should be a high disease occurrence in those carrying a pathogen, evidence of a serological response to the pathogen, and the success of vaccination prevention. Direct visualization of the pathogen, the identification of different strains, immunological responses in the host, how the infection is spread and, the combination of these should all be taken into account to determine the probability that an infectious agent is the cause of the disease. A conclusive determination of a causal role of an infectious agent for in a particular disease using Koch's postulates is desired yet this might not be possible.[1]

The leading cause of death worldwide is cardiovascular disease, but infectious diseases are the second leading cause of death worldwide and the leading cause of death in infants and children.[2]

Other causes

Other causes or associations of disease are: a compromised immune system, environmental toxins, radiation exposure, diet and other lifestyle choices, stress, and genetics. Diseases may also be multifactorial, requiring multiple factors to induce disease. For example: in a murine model, Crohn's disease can be precipitated by a norovirus, but only when both a specific gene variant is present and a certain toxin has damaged the gut.[3]

List of diseases associated with infectious bacteria and viruses

A list of the more common and well-known diseases associated with infectious pathogens is provided and is not intended to be a complete listing.

Asthma Mycoplasma pneumoniae[4] and Chlamydia pneumoniae infections are associated with the onset and symptoms of asthma.[5]

Chronic fatigue syndrome Chronic fatigue syndrome (also known as myalgic encephalomyelitis) is associated with enteroviruses (such as Coxsackie B virus),[31][32] human herpesvirus 6 variant A,[33] human herpesvirus 7,[34] and parvovirus B19.[35][36] The bacteria Coxiella burnetii[37] and Chlamydia pneumoniae[38] are known causes of chronic fatigue syndrome (antibiotics can cure these bacterial forms of chronic fatigue syndrome).
Common cold The common cold is also known as Acute rhinosinusitis (ARS) and is caused by a viral infection.[39] Efforts to develop vaccines are ongoing.[2]
Crohn's disease One study found ileocecal Crohn's disease is associated with viral species from the enterovirus genus (but note that all the study cohort with ileocecal Crohn's disease had disease-associated mutations in either their NOD2 or ATG16L1 genes).[40] Crohn's disease is associated with Mycobacterium avium subspecies paratuberculosis.[41] In a murine model, Crohn's disease is precipitated by the norovirus CR6 strain,[3][42] but only in combination with a variant of the Crohn's susceptibility gene ATG16L1, and chemical toxic damage to the gut. In other words, in this mouse model, Crohn's is precipitated only when these three causal factors (virus, gene, and toxin) act in combination.
Coronary heart disease Coronary heart disease is associated with herpes simplex virus 1 and the bacterium Chlamydia pneumoniae.[43]
Dementia Dementia is associated with herpes simplex virus type 1, herpes simplex virus type 2, cytomegalovirus, West Nile virus, bornavirus, and HIV. Dementia is also associated with the helminth Taenia solium (pork tapeworm), and with Borrelia species bacteria.[44]
Depression Depression is associated with cytomegalovirus[45] and West Nile virus,[46] and the protozoan parasite Toxoplasma gondii.[47] It is thought that depression may be precipitated by the effect of immune signals (such as pro-inflammatory cytokines) reaching the brain from infections located in the peripheries of the body.[48][49]

Major depressive disorder is associated with bornavirus,[50] as well as Bartonella[51] and Borrelia[44] species bacteria.

Obesity

Obesity is also associated with higher gut levels of certain Bacillota bacteria in relation to Bacteroidota bacteria. Overweight individuals tend have more Bacillota bacteria (such as Clostridium, Staphylococcus, Streptococcus, and Helicobacter pylori) in their gut, whereas normal weight individuals tend have more Bacteroidota bacteria.[78]

Schizophrenia Schizophrenia is associated with bornavirus,[50] the bacterium Chlamydia trachomatis,[85] as well as Borrelia species bacteria.[44] Schizophrenia is also linked to neonatal infection with Coxsackie B virus (an enterovirus), which one study found carries an increased risk of adult onset schizophrenia.[86] Prenatal exposure to influenza virus in the first trimester of pregnancy increases the risk of schizophrenia by 7-fold.[87]
Severe acute respiratory syndrome Severe acute respiratory syndrome is a viral disease. Efforts to develop a vaccine are ongoing.[2]
Stroke Stroke is associated with the bacteria Chlamydia pneumoniae,[88] Helicobacter pylori,[89] Mycobacterium tuberculosis,[90] and Mycoplasma pneumoniae,[91] as well as the virus varicella zoster virus[92] and Histoplasma species fungi.[93]

Aggravating or contributory microbes in Tourette's may include the bacteria Mycoplasma pneumoniae,[96] Chlamydia pneumoniae, Chlamydia trachomatis, and the protozoan parasite Toxoplasma gondii.[97]

Vasculitis Vasculitis is associated with HIV, parvovirus B19,[69] and hepatitis B virus. The hepatitis C virus is an established cause of vasculitis.

Epidemiology

Infectious pathogen-associated diseases include many of the most common and costly chronic illnesses. The treatment of chronic diseases accounts for 75% of all US healthcare costs (amounting to $1.7 trillion in 2009).[98]

History

One of first examples of systematic study of disease causation was Avicenna, in the tenth century. The history of infection and disease were observed in the 1800s and related to the one of the tick-borne diseases, Rocky Mountain spotted fever. The cause of viral encephalitis was discovered in Russia based upon epidemiological clustering of cases. The virus causing this illness was isolated in 1937. The rash typical of Lyme borreliosis was identified the early 1900s.[1] Historically, some chronic diseases were linked or associated with infectious pathogens.[99][100][101]
