“Patients often find it a debilitating and embarrassing disease with a high degree of morbidity; and at the same time treating physicians generally find it a difficult disease to treat. Patients therefore hide their disease and choose to suffer in silence rather than to seek help. Physicians similarly often adopt a reductionist approach rather than seeking insight in the face of the clinical challenge.”

Global Assessment Tools

From 1996 to 2007 there has been a slow development of HS-specific tools for objectively and subjectively assessing and measuring this disease over time. The expert recommendation is that HS needs to be classified into one of three stages and objective and subjective data on the evolution of HS needs to be recorded over time using standard Dermatology Quality of Life measurements (DLQI/Skindex), a visual analog scale for pain, and use of the Modified Sartorius Scale in order to accurately record loco-regional severity of the disease over time [6]. Increased global use of the Modified Sartorius Scale will aid in the validation of these standard assessment tools as a means to reproduce satisfactory data on treatments which aggravate or relieve HS. Additional objective evidence can be gained by the photography and ultrasound imaging of affected areas. [1-6].

Assessment tools for HS have developed in spite of, and perhaps even because of, a lack of standardized criteria for what exactly constitutes HS. Comparing the efficacy or lack of success of treatments for HS between studies is problematic if studies do not disclose a diagnostic methodology. There has been no global consensus on how to diagnose HS, and therefore no studies performed which validate criteria for the diagnosis of this mysterious disease. This lack of uniformity and consensus needs to be resolved by the collection of standard data via recommended assessment tools, and perhaps from this data, standard diagnostic criteria for HS could be developed. Until such time, it is essential that treating physicians and researchers include their diagnostic criteria in patient medical records, published case reports, presentations, clinical trials and studies.

Expert Medical Perspectives
QOL conclusion for physicians: The analysis of QoL measures confirms the strong impact of HS. A subgroup of patients seems to be more affected; namely, patients with an early onset of their disease, with a long disease duration, with continuous evolution and with a predominately pelvic location. Future trials should be targeted on this subgroup. The impact upon QoL is strongly correlated with pain. Therefore, criteria of treatment evaluation should include, in addition to the standardized physician’s report, the patient’s viewpoint obtained with at least a dermatological QoL questionnaire and the pain VAS.
