Id reaction of the skin during a hyperergic phase of a tuberculosis infection.
A distinction is currently being made:
Papulonecrotic tuberculide.
Tuberculosis cutis lichenoides.
Erythema induratum. Depending on the disease.
Depending on the disease.
Important for the diagnosis position are that...
...organ tuberculosis.
... a clinical substrate is present.
... a distinctly positive tuberculin test was made.
... the symptoms subside after antitubercular therapy.
Therapy regimen:
The initial phase should last 8 weeks/2 months. During this time, the majority of bacteria are killed. In the following therapy phase (which lasts for months) the remaining bacteria are eliminated. The anti-tubercular therapy should be continued for at least 2 months after the skin is free of symptoms.
The therapy should last individually between 12-24, but at least 6 months!
Induction phase (2 months):
Rifampicin p.o. 10 mg/kg bw/ d
Isoniazid p.o. 5 mg/kg bw. (with Vit B 6)
Pyrazinamide p.o. 35 mg/ bw/ d possibly in combination with Allopurinol!
Ethambutol p.o. 15 mg/kg bw/ d
A clear improvement can be seen in the vast majority of cases after 1 ½ months.
- Consolidation phase:
Induction phase (2 months):
Rifampicin p.o. 10 mg/kg bw/ d
Isoniazid p.o. 5 mg/kg bw. (with Vit B 6)
Ethambutol p.o. 15 mg/kg bw/ d (may also be omitted if isoniazide resistance is excluded)
HIV Patient: Therapy must take place at ≥ for 7 months. Ethambutol should be replaced by streptomycin p.o. 15-20 mg/kg bw/ d (from > 60 J. max 750 mg) for additional therapy with NNRTI.Tuberculid in a child: transformation from papulonecrotic to lichen scrofulosorum.
