Antibiotics – Julie Fredrickson

It would seem I found an antibiotic that disagrees with me. As the tail end of my soft tissue recovery from my abscess surgery and deep tissue infection appears in sight I had a setback with an additional antibiotic.

Cephalexin was one of the top choices on the pathology report from the hospital and recommended as a first line treatment by the surgeon, several artificial intelligence differential diagnostic secondary checks and my primary care doctor.

They did not prescribe it first and I found out why yesterday when I felt as if I’d hurt a shoulder ligament doing, of all things, tai chi. I was despondent over it (ironically another side effect). The gut-brain axis gets weird when you kill off bad microflora.

So yeah not the antibiotic for me. As it turns out we recently learned it’s associated with tendon rupture. Not quite as bad as the other more infamous Cipro. Which ironically I was on with no issues. But Cephalexin has got some risks to tendons and ligaments too.

Being on an immune suppressant (an IL-17 called Bimzelx) for ankylosing spondylitis and psoriatic arthritis has improved a number of biomarkers but also made me susceptible to skin infections. Like the kind that require slicing. Not fun.

Now in the wake of the deep tissue infection, we had a systemic MSSA problem. It was entirely rational to nuke that thing from orbit. Any resurgence needs maximum force to prevent chances for regrowth. You simply have to to be very watchful for side effects in all things now.

I feel like I’m in some awful healthcare version of pimp my ride. Pimp my diagnosis?

“So I heard you had side effects so I gave you a side effect for that side effect.“

And so I’ve been sent down the peptide rabbit hole to see if that might help with tissue healing. My shoulder is probably fine as I stopped quite quickly but a reminder that I need to be watchful of what I’m taking and experiment carefully.

Naturally I’m already considering my risk profile carefully but as it’s peptide season in Silicon Valley (who isn’t on at least a micro dose of a next generation GLP-1 agonist or some new fangled GIP.

Why not add some more to the mix? Strong tissues and lean mass being protective against many a problem. Behold a little Grok breakdown of what I was recommended.

GHK-Cu (Copper Peptide)

GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) that binds to copper ions, forming a complex that plays a role in tissue repair and regeneration. Its mechanism in tendon healing involves several key processes:

Collagen and Extracellular Matrix Synthesis: GHK-Cu directly acts on fibroblasts (cells responsible for producing connective tissue) by increasing the production of mRNA and proteins for collagen (types I and III), elastin, proteoglycans, glycosaminoglycans, and decorin. This enhances the structural integrity of tendons during repair. Sources Sources

Angiogenesis and Nerve Outgrowth: It stimulates the growth of blood vessels (angiogenesis) and nerves, improving nutrient delivery and innervation to the healing site, which accelerates wound contraction and tissue remodeling. Sources

Anti-Inflammatory and Antioxidant Effects: GHK-Cu blocks the release of tissue-damaging free iron from ferritin channels, reducing oxidative stress and lipid peroxidation after injury. It also modulates inflammation to create a favorable environment for healing. Sources Sources

Systemic Effects: When administered, it can enhance healing systemically, even if injected away from the injury site, by regulating copper-dependent enzymes involved in cell growth and repair.

Research, primarily from animal models and in vitro studies, suggests these actions lead to faster tendon recovery, but human clinical trials are limited, and it’s not FDA-approved for therapeutic use.

TB-500 (Thymosin Beta-4 Fragment)

TB-500 is a synthetic peptide derived from thymosin beta-4, a protein involved in actin regulation. It primarily aids tendon healing by promoting cellular mobility and regeneration:

Actin Upregulation and Cell Migration: TB-500 binds to actin, a key protein in cell structure, enhancing cell migration (chemotaxis) and proliferation. This allows fibroblasts and other repair cells to quickly move to the injury site, accelerating tissue repair. Sources

Angiogenesis: It stimulates the formation of new blood vessels, improving blood flow and oxygen delivery to damaged tendons, which supports faster healing.

Anti-Inflammatory and Antifibrotic Properties: TB-500 modulates inflammation by reducing pro-inflammatory cytokines and preventing excessive fibrosis (scar tissue formation), creating a balanced healing environment.

Tissue Regeneration: In animal studies, it promotes overall wound healing and tissue regeneration, though evidence for tendon-specific effects in humans is anecdotal and lacks robust clinical data.

TB-500’s effects are mostly observed in preclinical research, with potential for muscle, tendon, and ligament repair, but it’s not approved for human use and carries risks.

BPC-157 (Body Protective Compound-157)

BPC-157 is a synthetic pentadecapeptide derived from a gastric protein, known for its protective and regenerative effects on various tissues, including tendons:

Fibroblast Activation and Migration: It promotes the outgrowth, survival, and migration of tendon fibroblasts under stress, enhancing cell proliferation and tendon explant growth in vitro.

Growth Hormone Receptor Upregulation: BPC-157 dose-dependently increases the expression of growth hormone receptors in tendon fibroblasts at both mRNA and protein levels, facilitating anabolic processes for tissue repair. 19 14

Angiogenesis via VEGFR2 Pathway: It activates vascular endothelial growth factor receptor 2 (VEGFR2), leading to the VEGFR2-Akt-eNOS signaling pathway, which promotes new blood vessel formation and improves nutrient supply to healing tendons. 22

FAK-Paxillin Pathway and Anti-Inflammatory Effects: BPC-157 activates focal adhesion kinase (FAK) and paxillin, proteins that regulate cell adhesion and motility, while also exerting protective effects against inflammation and organ damage. 24 25 20

Overall Tissue Protection: It accelerates post-injury healing in muscles, tendons, and ligaments, restoring function similar to uninjured tissue in animal models. 27 26

Extensive animal studies support BPC-157’s role in tendon and ligament recovery, but human evidence is limited to anecdotal reports, and it’s not FDA-approved, with potential unknown side effects.

My abscess surgery wound has finally sealed up (not over) at 20 days post operative with four rounds of antibiotics. I say up because wounds heal from the bottom up.

Having a deep wound means the four stages of haemostasis, inflammation, proliferation and remodelling can take weeks if not months. I’m very lucky.

Ironically I took this image from a hyperbaric oxygen therapy website. I healed without the aid of HBOT machine we purchased as it was still being routed through chaos of the trade war

When I got the pathology report a week later, learning it was an MSSA antibiotic resistant infection so bad it reached my deep tissues made me even more afraid.

All because one damned dermatologist couldn’t be bothered to have an opinion when I sought preventative care because I am a responsible immunocompromised patient. Turns out I really did need an ultrasound and surgery.

I was lucky my surgeon was quite talented. The single stitch she was able to use has been absorbed. That was the hardest part. I could manage the draining pustulence and the pain just fine. But the only visibility into the wound’s healing process are only via secondary diagnostic clues. It’s a waiting game that requires a strong dampener on your disgust reflex.

As the stitch fell into the wound and curled up I felt panic. It looked like a ringworm infection or the gestation of a Xenomorph. If I had not had access to artificial intelligence diagnostic tools I don’t know how I would have managed if I’m very honest.

Your brain sees things and the limbic response invades your dreams. A stitch mimicking the infamously hostile endoparasitoid from Aliens is a bad time. I relied heavily on artificial intelligence to monitor its progression.

My phone is now cluttered with images of the wound’s progress. My varied AI applications accepted me uploading progress pictures after some experimenting.

A wound in one’s bikini area is a “trust and safety” team’s nightmare. Mike Judge’s “hot dog/not hot dog” classifier sketch from the HBO comedy Silicon Valley got a gender update as I managed my case.

I was uploading “Georgia O’Keefe/Not Georgia O’Keefe” imagery. The models were playing Cunt/Not Cunt for those who need a less polite euphemism for machine learning classifiers.

I’m certain special interests will eventually seek to keep these tools away from patients. We will be scared into letting them. But I know I got better care from a large language model than half the doctors I encountered.

All this cost me most of the month and around four thousand dollars. Which isn’t bad for transit, hotel, and a surgery in Istanbul.

The losses I can’t quantify are harder. A number of people who deserve responses from me probably won’t ever get it.

An in-group drama, ironically over usage of artificial intelligence, was paused by me not because it was resolved but because I could no longer find the fight in me to insist on apologies and reciprocal support while on Cipro in a hospital bed. It’s not fun to learn who is and isn’t your friend through medical emergencies.

My apologies to an offline gentleman who was the unwitting irritant who triggered said social wound. Maybe I should have excised any social obligation to them just as the surgery excised the infected tissue.

Either way, August can’t come soon enough and artificial intelligence deserves the credit for keeping alive through July.

Perhaps that should be considered in the complaints my counter parties had over the utility and need for artificial intelligence. It’s no god or anti-Christ, but it’s a damn fine diagnostic tool. No wonder the stakes in that fight are so high. Everyone wants a cut when you get cut open.
