Intervention model description: Thirty new patients with early stage mycosis fungoids will be allocated to proper treatment modality that differ according to the patient's clinical state following kasralainy phototherapy unit protocol
Primary purpose: DIAGNOSTIC

Brief summary: To compare tissue and serum level of NLRP1, NLRP3 inflammasomes and Interleukin (IL)-18 in mycosis fungoids patients and normal controls.

To compare tissue and serum level of NLRP1, NLRP3 inflammasomes and Interleukin (IL)-18 in mycosis fungoids patients before and after different treatment modalities.

Detailed description: Thirty patients with early stage mycosis fungoids and thirty normal healthy controls will be recruited. An informed written consent will be obtained from all patients and controls.

Data collection Demographic data Each patient will be subjected to detailed history taking as regards age, sex, residence, marital status, smoking, special habits of medical importance, duration of the disease, associated diseases, previous therapy and family history.

Evaluation of the clinical response The patients will be photographed and evaluated at baseline and at the end of treatment .

Clinical scoring of five mycosis fungoids skin lesions will be done using Composite assessment of index lesion severity (CAILS) (Oslen et al., 2011).

Clinical scoring of whole body affection will be done using Modified Severity Weighted Assessment tool (MSWAT) (Oslen et al., 2011).

Assessment of response of mycosis fungoids patients to our treatment modalities will be done using Objective response rate (ORR) (Oslen et al., 2011).

Treatment (therapeutic intervention):

Thirty new patients with early stage mycosis fungoids will be allocated to proper treatment modality that differ according to the patient's clinical state following kasralainy phototherapy unit protocol End of the study will be defined as achieving clinically near complete clearance of the lesion from which a tissue biopsy will be taken or a maximum of 48 sessions of treatment.

Biochemical assessment and pathological assessment (Diagnostic intervention) :

Two lesional skin 4 mm punch biopsies will be taken from same lesion in all thirty patients and once from all thirty normal healthy controls.

Three milliliter serum samples will be taken from all thirty patient before and after treatment and once from all thirty healthy controls.

one skin biopsy and serum samples before treatment will be subjected to biochemical assessment for measurement of NLRP1, NLRP3 inflammasomes and Interleukin (IL)-18 by ELISA (Enzyme linked immunosorbent assay) technique.

The other skin biopsy will be used for pathological assessment. The same process will be repeated after treatment for patients only to assess the percent change in all parameters and in lymphocytic infiltration .

Fate of tissue and serum samples Tissue samples used for biochemical assessment will be completely crushed to extract protein for ELISA, any residual biological tissue will be safely discarded in the incinerator.

Tissue samples used for pathological assessment will be put on paraffin blocks then on slides that will be kept in our department.

Serum samples will be collected in special containers to be sent to the official site in the hospital to get rid of them.

Intervention:

Diagnostic intervention : biochemical assessment for measurement of NLRP1, NLRP3 inflammasomes and Interleukin (IL)-18 by ELISA (Enzyme linked immunosorbent assay) technique in tissue and serum samples of all thirty patients and healthy controls.

Therapeutic intervention : Thirty new patients with early stage mycosis fungoids will be allocated to proper treatment modality that differ according to the patient's clinical state following kasralainy phototherapy unit protocol
