The following laboratory tests may be helpful in the evaluation of hidradenitis suppurativa HS: CBC count with differential and platelet counts Assessment of erythrocyte sedimentation rate C-reactive protein assay Urinalysis Serum multiphasic analysis with determination of the serum iron level and serum protein electrophoresis Patients with acute lesions may have an elevated erythrocyte sedimentation rate, elevated white blood cell count occasionallya low serum iron level, and serum protein abnormalities on electrophoresis.
References Imaging Studies Ultrasonography of the hair follicles and dermal thickness in hidradenitis suppurativa patients may reveal abnormalities in the deep part of the follicle.
In the genitofemoral region, perilesional clinically normal hair follicles have an abnormal shape and are significantly wider in the deep part of the dermis, compared with control samples. Mean axillary and genitofemoral skin is significantly thicker in patients with hidradenitis suppurativa than in healthy control subjects.
Thickened skin may play a role in the pathogenesis of hidradenitis suppurativa. References Other Tests Bacteriologic analysis should include bacteriologic sampling and cultivation. Almost every microorganism known to bacteriologists can be isolated from hidradenitis suppurativa lesions; these microorganisms include Buccal film thesis, gram-positive and gram-negative rods, and the full range of fecal bacteria.
Compared with the normal epidermis and type I epithelium, types II and III epithelia have Dsc2 and Dsg3 in all layers, whereas Dsc3 is restricted to the basal and parabasal layers. CK19 is commonly found in the basal cells of noncornifying stratified squamous epithelia, such as in the outer root sheath ORS of the hair follicle.
The strongly inflamed CKpositive parts of the sinus epithelium show no signs of terminal squamous differentiation ie, nuclei were present in the highest suprabasal layers, and keratohyalin granules were absent. Instead, the inflamed CK—positive parts resembled epidermal keratinocytes grown in organotypic culture, which can be induced to build a noncornifying epithelium and to express CK19 with the addition of retinoic acid to the culture medium.
In all specimens in one study, type I epithelium near the opening of the sinus showed strong similarities to the upper pilosebaceous duct from which the inflammation process seemed to emerge. In both normal pilosebaceous duct epithelium and cornifying type I sinus epithelium, CK5 and CK14 are restricted to the basal layer, CK10 and Dsc1 antibodies label the suprabasal cells, Dsg1 and Dsg3 are present in an epidermislike pattern, and CK2e is absent.
The relationship of the sinus epithelium to the hair follicles and the apocrine glands has long been debated. Thus, CKs 5 and 14 and Dsg2 always remain restricted to the basal cell layer of the sinus epithelium, whereas in the subinfundibular ORS, they are also expressed in the suprabasal layer.
The relationship of the sinus epithelium to hair follicles and apocrine glands is in agreement with the theory that hidradenitis suppurativa lesions are caused by follicular plugging and subsequent rupture of the follicular epithelia.
The exact role of inflammation in such patterns of differentiation has yet to be elucidated. Thus, in another study of the hidradenitis suppurativa cytokeratin expression reported by Kurokawa et al, the draining sinus tract epithelium of hidradenitis suppurativa lesions were divided into 3 components: CK17, which is normally present in the suprabasal layers of healthy skin, represents a useful marker for differentiation of epithelial cells.
It is a spacial keratin and has a function related to the maintenance of the 3-dimensional cytoskeleton structure of human adnexal glands. Thus, the absence of CK17 may reflect a fragile follicular structure, resulting in rupture of the follicle, which subsequently forms a subcutaneous abscess.The first studies describing the incorporation of bioactive molecules into solid polymers for achieving a sustained release profile were conducted in the 50's and 60's.

Hidradenitis suppurativa is a disorder of the terminal follicular epithelium in the apocrine gland–bearing skin. This condition is a chronic disabling disorder that relentlessly progresses, frequently causing keloids, contractures, and immobility.
