Decolonization of staphylococcus aureus and therapeutic test to assist the diagnosis in me/cfs, long covid, post-vaccine covid syndrome and other diseases with fatigue and/or chronic pain

Abstract:

Nasal Decolonization is performed with an antiseptic such as Povidone-iodine. For the Therapeutic Test an Antibiotic such as Flucloxacillin plus Probiotics or other supplements with an effect against S.aureus is indicated.

There is a Subgroup of patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Long COVID Syndrome or PACS who present a persistent bacterial infection that affects the upper respiratory tract, and especially at the level of the nostrils.

We estimate that this Subgroup of patients presenting this persistent infection as a causal or contributing factor would be around a third of all cases.

The most frequent causative agent of these persistent and/or recurrent infections is the Staphylococcus aureus bacterium. According to the studies carried out, this bacterium is present in the nasal passages of between 16 and 36% of the general population, who are asymptomatic carriers of Staphylococcus aureus, and are often unaware of it.

In health professionals who carry out care work, the percentage of carriers can exceed 50%. In a recent study carried out in health workers and medical students, 65% of nasal carriers of S. aureus were reported, and of these, 74% were multidrug-resistant (MDR) bacteria and 69% were biofilm-forming bacteria [1].

Chronic fatigue and immune dysfunction syndrome associated with Staphylococcus spp. bacteraemia responsive to thiacetarsamide sodium in eight birds of prey

Abstract:

Chronic fatigue and immune dysfunction syndrome (CFIDS) is a recognized human illness with zoonotic implications that is rarely described in animals. Eight birds of prey examined between 1992 and 1995 and sharing common symptoms (asthenia, inability to fly, poor appetite and emaciation) underwent laboratory tests revealing immunodeficiency, anaemia, high creatine kinase levels and low serum magnesium levels. Diagnosis of CFIDS was based upon these features.

The effectiveness of an arsenic-based medication, thiacetarsamide sodium, administered intravenously for 2-3 days at low dosages (0.1 ml/kg/day) has been demonstrated by checks carried out 10, 20 and 30 days after therapy. The symptoms and the immune and haematological dysfunctions disappeared within 2-4 weeks of treatment. In all patients, micrococcus-like organisms found adhering to the outer surface of many red blood cells, had disappeared at post-treatment controls. Two of five blood cultures were positive for Staphylococcus spp. (S. intermedius and S. xilosus). Consideration is given to the pharmacological activity of an arsenic-based drug in animal illnesses resembling CFIDS.

Chronic fatigue syndrome (CFS) associated with Staphylococcus spp. bacteremia, responsive to potassium arsenite 0.5% in a veterinary surgeon and his coworking wife, handling with CFS animal cases

Abstract:

Chronic fatigue syndrome (CFS) in human patients remain a controversial and perplexing condition with emerging zoonotic aspects. Recent advances in human medicine seem to indicate a bacterial etiology and the condition has already been described in horses, dogs, cats and birds of prey in association with micrococci-like organisms in the blood.

To evaluate the possibility of a chronic bacteremia, a veterinary surgeon (the author) and his coworking wife, both diagnosed with CFS and meeting the CDC working case definition, were submitted to rapid blood cultures and fresh blood smears investigations.

Blood cultures proved Staph-positive and micrococci-like organisms in the blood were repeatedly observed in the 3-year period preceding the arsenical therapy, during which several medicaments, including antibiotics, proved unsuccessful. Following treatment with a low dosage arsenical drug (potassium arsenite 0.5%, im., 1 ml/12 h, for 10 days) both patients experienced complete remission. At the post-treatment control made 1 month later, micrococci had disappeared from the blood, and the CD4/CD8 ratio was raising.

Chronic Fatigue Syndrome (CFS) in 15 dogs and cats with specific biochemical and microbiological anomalies

Abstract:

A great deal of controversy and speculation surrounds the etiology of Chronic Fatigue Syndrome (CFS) in human patients and the existence of a similar illness in animals. To evaluate the association with a presumptive staphylococcal infection and bacteremia, seven dogs and eight cats diagnosed with CFS (two meeting the CDC working case definition) were submitted to rapid blood cultures and fresh blood smears investigations.

Nine out of 15 blood cultures proved Staph-positive and four isolates were specified as S. xilosus (3) and S. intermedius (1). The presence of micrococci-like organisms in the blood was of common observation among these subjects, in association with fatigue/pain-related symptoms and biochemical abnormalities suggestive of a myopathy. Following treatment with a low dosage arsenical drug (thiacetarsamide sodium, Caparsolate, i.v., 0.1 ml/kg/day) all patients experienced complete remission. Micrococci disappeared from the blood at post-treatment controls made 10-30 days later. The outcomes were compared with those of five healthy controls and five ‘sick with other illness’ patients showing significant difference.
