A rheumatic syndrome of possibly allergic origin, usually affecting children
and adolescents, and characterized by high fever, exanthema, arthralgia,
leukocytosis, and increased sedimentation rate. Also called Wissler-Fanconi

The Biochemical class in the current schema does not have a biomarker_term or measurement_term slot. However, MAXO does have relevant terms:

  • MAXO:0035093 - erythrocyte sedimentation rate measurement
  • MAXO:0000551 - C-reactive protein biomarker assessment

Options:

  1. Add these MAXO terms to the disease-level notes/context until the schema supports biomarker terms
  2. Propose a schema enhancement to add a measurement_term slot to the Biochemical class
  3. Keep as-is with the existing freetext name field

The existing entries are correctly capturing the presence/elevation status; adding formal term bindings would require schema modification.

Agreed - the evidence for dapsone clearly shows it was used as part of a 3-drug combination (naproxen + dapsone + prednisolone). Options:

  1. Restructure as combination therapy entry: Create a single treatment entry representing the combination regimen
  2. Add explicit notes: Note in description that dapsone was used as part of combination therapy with NSAIDs and corticosteroids
  3. Cross-reference: Add a notes field indicating "Used in combination with corticosteroids and NSAIDs"

The current schema may not have a formal "combination_therapy" slot. If this is a pattern seen across cancer entries, we could adopt that pattern here as well.

explanation: The abstract indicates corticosteroids were part of successful therapy.

I think this is fine but better to be explicit about combos

Agreed - the azathioprine entry should clearly indicate combination therapy with corticosteroids. The evidence states "imuran in combination with corticosteroids."

Suggested restructure:

- name: Azathioprine plus corticosteroids
  description: Immunosuppressive combination therapy using azathioprine with corticosteroids for disease control.
  treatment_term:
    preferred_term: immune suppressant agent therapy
    term:
      id: MAXO:0000297
      label: immune suppressant agent therapy
  notes: Combination regimen - azathioprine (imuran) with corticosteroids

Or if MAXO has a specific combination therapy term, that would be preferable.

# Subsepsis allergica
**Authors:** Hans Wissler
**Journal:** Ergebnisse der Inneren Medizin und Kinderheilkunde (1965)
**DOI:** [10.1007/978-3-642-94912-8_6](https://doi.org/10.1007/978-3-642-94912-8_6)

## Content
1943 habe ich anhand von 5 Fällen unter dem Titel “Über eine besondere Form
sepsisähnlicher Krankheiten“ das Krankheitsbild der “Subsepsis hyperergica“
beschrieben. Fanconi hat 1946 einen weiteren Fall mitgeteilt und den Namen in
„Subsepsis allergica“ umgeändert. Die Krankheit fand zunächst wenig Beachtung.
Einer ersten Arbeit von Keyzer in Holland 1946 folgten bis 1950 noch diejenige
von Künstler 1948 (jedoch unter dem Namen „Rheumatismus“) und von Fontan und
Verger 1948. Nach 1950 wurde das Krankheitsbild besser bekannt, so daß bis jetzt
43 Publikationen zur Verfügung stehen. Dazu kommen noch einige mir im Original
nicht zugängliche aus Osteuropa, die bei Biedrzicka zitiert sind. 1958 und 1959
habe ich das damals vorhandene eigene und fremde Material zusammengestellt (51,
52). Mit einer Ausnahme (N. Homma, Tokyo) stammen alle Publikationen von
Kontinentaleuropa, die meisten aus Deutschland, Frankreich und Italien. Im
angelsächsischen Sprachgebiet wird das Krankheitsbild bis jetzt nicht anerkannt.
Sicher ist nur ein Teil der beobachteten Fälle veröffentlicht worden, wie mir
zahlreiche Anfragen gezeigt haben. — Zunächst haben nur die Pädiater die
Krankheit gesehen, neuerdings sind aber auch Fälle bei Erwachsenen
bekanntgegeben worden (23, 25, 38).
