Because of the size of the spa - only nine treatment rooms and two couples' suites - you'll likely never be cramped in the room but that's irrelevant, because just on the other side is the relaxation area where you'll want to spend the majority of your non-spa-treatment time.
HLA B27 was not determined in 7 patients with SpA and 25 non-SpA patients.
Regarding global assessment, one recent study investigated the inter-observer agreement for global evaluation of MRI of the SIJ in SpA versus non-SpA patients.
As shown in table 3, 113 patients were diagnosed with SpA (66 with nrSpA and 47 with definite AS) and 209 patients were diagnosed as non-SpA.
Data on fertility and teratogenicity have generally been drawn from non-SpA populations, although it is clear that foetal and maternal risks are small with TNF blockade treatment.
By adopting a whole genome profiling approach this study has identified gene signatures differentiating SpA from non-SpA samples and highlighting pathways that might play key pathophysiological roles in AS.
Thus, patients with PsA could probably be divided into SpA type and non-SpA type, although synovial histopathological data from peripheral joints indicate that any type of PsA resembles other SpA subtypes more than rheumatoid arthritis.
Further studies have also shown that bone marrow edema at entheses is common in non-SpA-related conditions of the shoulder and heel, and it is the size of the lesion together with its association with bone erosion that has the highest specificity for SpA [ 56].
