Antibiotic Spinal Therapy: Can We Just Cut It Out?

There has been much controversy since the inception of antibiotic spinal therapy; some warranted, much based on questionable motives unrelated to the concerns regarding documented evidence and patient suffering as well as consequences to society in terms of lost productivity.

Well noted is the recent change of the name to Cutibacterium from Propionibacterium acnes. Now pronounced as cut-ee-bacterium, presumably derived from the cutaneous nature involved with the skin condition acnes, it’s note as an opportunistic pathogen does not make it cute, however, many surgeons would like to cut it out, especially when it comes to back pain and/or leg pain (sciatica).

A 2019 study in the European Spine Journal highlights some problems in the understanding of clinically relevant Modic I changes and back/leg pain, as well as virtue/alarm signaling.[1]

In this article, the authors performing surgery, state, “Cutibacterium acnes (Propionibacterium acnes) has been found in painful degenerated discs, why it has been suggested treating patients with LDH/LBP with antibiotics.” Is this a question? Is the “why” supposed to be “where”? In either case, they are clearly questioning using antibiotics for LDH/Low Back Pain.

The authors continue, “As multidrug-resistant bacteria are a worldwide concern, new indications for using antibiotics should be based on solid scientific evidence.” I agree, however, this is not new and it is based on well established scientific evidence dating over a decade, however; the authors/surgeons seem to ignore much of the specific scientific evidence, choosing to generalize based on the least scientifically sound evidence and focus on scare tactics. Cut it out!

No reasonably treating doctor is suggesting treating disc herniation and or low back pain using antibiotic spinal therapy. This is common sense and would seemingly eliminate the “where” explained above. This is simply absurd! They ignore the specific indications established for a trial of antibiotics using the protocol indicated only in a specific subset of patients exhibiting Modic Type I changes; a self-limiting, non-contagious condition.

The authors indicate Modic changes and not specifically Modic Type I, as there are very different subjective and objective findings that are well established. Similarly, I cannot imaging where surgery is indicated for every instance of low back pain and/or sciatica, however, I can easily make a statement that we should just cut it out where we find it. Works for me – if I’m a surgeon.

How about some reasonable alternatives and some specific indications, presuming there are specific indications for surgical treatment to minimize failed back surgery, possible complications, and side effects. The more specific we get, the less we are concerned about multidrug-resistant bacteria and the worldwide concern; as if the protocol established for successful implementation of antibiotics for functionally disabling Modic I changes would be the main culprit. This is a concern if we are treating all instances of “Modic changes” and any related disc herniation and/or low back pain, however, to suggest this is irresponsible and self serving regardless of the discipline.

Since the ground breaking work of Dr. Albert[2] over a decade ago, many in the medical community have suggested this will lead to treating all back pain with antibiotics. However, surgeons have addressed this with surgery[3] and others address it with alternative, more expensive biologics[4] with significantly more ominous side effects. All in the name of preventing antibiotic abuse and the worldwide concern about multidrug-resistant bacteria? Really?

Even with scientific proof that antibiotics can successfully manage Modic tye I changes in select patients[5], the hysteria just increases. However, the specific history and objective findings for clinically relevant Modic I changes related to subclinical bacterial infection have been outlined and do not represent anyone with Modic changes and back pain. Are antibiotics used before, during, or after surgery? Maybe we should cut that out?

modic back painBiopsies seeking to prove P. acne in sampled discs range from 0 to 55%. Obtaining sterile biopsies from the vertebra and disc and analysis is technically and methodologically challenging. This has led to different conclusions being drawn from the literature. With such contradictory data based on current methods, these conclusions should not be the basis for determining treatment.

The FISH (fluorescence in situ hybridization) method provides the basis for more solid conclusions than previous investigations using PCR techniques and culturing methods[6]. This can detect a protective biofilm inside the disc caused by some strains of the Propionibacterium acne.[7] This biofilm induces an inflammatory reaction with resulting tissue
damage.[8]

Biofilm is a slimy, thin, layer which binds the bacteria together. It also functions as a chemical communication system and provides protection against the outside environment like attacks from the immune system. So, attention clinically must be focused on a more fundamental discussion of relevant functional effects that Modic changes has on the patient instead of broad statements based on questionable methodological issues.

The scientific evidence indicating the effectiveness of antibiotic spinal therapy for Modic change and back pain is compelling, however; despite general lack of answers calling for replication, it is clearly not an isolated isolated phenomenon.[9] Antibiotics should be considered as a treatment option a special subgroup of patients with persistent back pain and confirmed Modic I changes, considering it can be a chronic disabling condition that can occur in the most productive time of life.[10] Rightly have Manniche and O’Neill noted the evidence for antibiotic spinal therapy and future indications based on scientific literature and clinical experience.[11]

Antibiotic Spinal Therapy: Diagnosing & Treating Chronic, Treatment Resistant Back Pain Where Low-Virulent Bacterial Infection Is Suspect

  • Patient presents with well localized and persistent back pain
  • Exacerbation with exercise therapy
  • Awakens during the night with pain
  • Reports stiffness for more than 30 minutes in the morning
  • Disc herniation or breach within the previous 2 – 3 years, with subsequent improvement of any sciatica, but back pain remains or increases
  • Conservative treatments explored without improvement
  • Average pain intensity greater than 4/10 with functional disability
  • MRI: Modic change Type I or I/II mixed within the relevant painful location

Antibiotic Spinal Therapy: Considerations

  • This is not a standardized treatment protocol in the medical community, yet
  • Treatment should be followed closely by the responsible doctor.
  • Patient education is crucial for best results and compliance
  • Treatment offered after careful consideration of the individual Modic change case
  • Patient’s pain is persistent with significant functional affect
  • Relevant conservative therapies explored without sufficient effect: Consider antibiotics (general practitioner or rheumatologist
  • Minimum single dose application: Amoxicillin/Clavulanic acid 500 mg × 3/day for 100 days.
  • Note common side effects and/or complications: fatigue, diarrhea, fungal infections, allergic reaction, liver-enzymes, etc.
  • Effects of antibiotics likely to manifest after 2 – 4 months. Slow improvements for following 12 months are often noted.

Questions For Future Management Of Modic Changes

  • Can we develop reliable methods of differential diagnostics of low-virulent infectious changes in comparison to strictly mechano-immunological?
  • Can we determine prevalence for an infectious pathway as a clinically important condition?
  • Are infectious pathway Modic changes preventable?
  • Can we identify patients for whom anti-microbial treatment is more efficacious as opposed to anti-inflammatory treatment?Which management protocol(s) are associated with the least complications and are most effective and for the patient as well as environment?

Regarding a 2019 article[12] where it was stated “We aimed to replicate the findings in the former randomised trial, it should be noted the study deviated from the former trial. The authors present criticisms of the trial by other authors, but fail to acknowledge responses by the previous study author directly addressing the criticisms.

This clearly sets the tone and bias of the study.

The aimed replication included 750mg of amoxicillin for 90 days, including both Modic I and II participants; whereas the original trial was amoxicillin–clavulanate (500 mg/125 mg) tablets three times a day, at 8 h intervals, for 100 days, including a double dose group that proved better efficacy.

The authors of this study indicate, “…we chose to include patients with type 2 Modic changes because differentiating between type 1 and type 2 Modic changes is of uncertain relevance…”, a rather suspicious statement given the well established differences, also not included in the original study.

The authors additionally state, “About 40-50% of patients with non-specific low back pain have Modic changes, and antibiotic treatment in subgroups of this large patient population could increase antibiotic resistance.” Another example of generalizing and alarmist statements, as nobody is suggesting treating All Modic changes and back pain with antibiotics! Did they?

Perhaps the almost thirty listed authors of the new study do not understand or want to broaden the term “replication” for intended effects.
