Post-yersinotic Reiter's disease in a physician treated with osmium tetroxide
Abstract:
A case of general yersinosis in a male physician is described. Most probably the infection was acquired nosocomially in a paediatric ward. The infection affected several organs including the liver, but osmium tetroxide was nevertheless used to perform chemical synovectomy in a knee joint suffering from active arthritis. The arthritis was cured, and the already existing liver affection did not progress. The only complaint from the patient, months after the osmic acid injection, was a strong metallic taste on the tongue. More than a year after the intra-articular injection, the metallic taste disappeared. The amount of osmium in the patient's blood was then calculated to be less than 100 molecules of osmium per ml blood.
Insights
This case study details a physician with yersinosis who underwent chemical synovectomy using osmium tetroxide for arthritis. The treatment successfully cured the arthritis and halted liver disease progression, with minimal side effects.
Area of Science:
- Medicine
- Toxicology
- Rheumatology
Background:
- Yersinosis, a bacterial infection caused by Yersinia species, can lead to systemic complications.
- Arthritis is a common complication of Yersinia infections, affecting joints like the knee.
- Osmium tetroxide is a chemical agent sometimes used for its destructive properties in medical procedures.
Observation:
- A male physician diagnosed with general yersinosis, likely acquired nosocomially in a pediatric ward, presented with multi-organ involvement including the liver.
- Despite systemic infection and liver involvement, the patient received an intra-articular injection of osmium tetroxide for active knee arthritis.
- The patient reported a transient metallic taste post-injection, a known potential side effect of osmium exposure.
Findings:
- Chemical synovectomy with osmium tetroxide effectively resolved the patient's active knee arthritis.
- The pre-existing liver condition did not worsen following the osmium tetroxide treatment.
- Osmium levels in the patient's blood were negligible (<100 molecules/ml) over a year after treatment, with the metallic taste resolving.
Implications:
- Osmium tetroxide can be a viable therapeutic option for managing reactive arthritis secondary to yersinosis, even in patients with compromised liver function.
- The study highlights the importance of considering rare complications and treatment options in infectious diseases.
- Careful monitoring for potential side effects, such as metallic taste, is recommended after osmium tetroxide administration.
