OE Journal. 2013;1(2):158 BMC Musculoskelet Disord. 2008 Jan 11;9:4.140 participants, >18 years of age, with spondyloarthropathy (SpA) were randomized to receive either a probiotic drink or a placebo over a 12 week period. The probiotic drinks were not any superior in improving well-being or bowel symptoms. Internet-based randomized controlled trial was a suitable economical method with a potential applicability in examining the complementary and alternative medicine interventions at low cost.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?

O Índice de Fragilidade é uma ferramenta que auxilia na interpretação de achados significativos, fornecendo uma medida de força para um resultado. O Índice de Fragilidade representa o número de eventos consecutivos que precisam de ser adicionados a um resultado dicotómico para que o resultado deixe de ser significativo. Um número pequeno representa um resultado mais fraco e um número grande representa um resultado mais forte.
Porque é que este estudo era necessário agora?
Complementary and alternative medicines (CAMs) are used in chronic and acute health conditions for maintaining wellness. However, the use of CAMs is limited, since there have not been many clinical trials performed on CAMs. This study evaluated the effectiveness of probiotics in the symptom control of spondyloarthropathy.
Qual era a principal questão de investigação?
Is the probiotic use superior to placebo in terms of well-being, bowel symptoms, and arthritis severity (disease activity and function) after 12 weeks of treatment?
- 65% (96/147) completed the entire 3 month long trial.
- CAM Outcome: No clinically significant differences were observed in the global well-being, bowel symptoms, or severity of arthritis between the two groups.
- Adherence to medication was comparable in both the groups, placebo=3938/5796 (67.9%) and intervention group= 3748/5544 (67.6%).
- No difference in the adverse event rates between the groups were recorded
De que é que me devo lembrar mais?
Internet-based tools were useful and economical for conducting a successful randomized controlled trials in low risk interventions. The probiotic did not improve well-being, disease activity, or function compared to placebo.
Como é que isto afectará o tratamento dos meus doentes?
The internet-based RCT is a feasible method to examine the CAM intervention. it is also is a cost-effective approach for assessing low-risk interventions.
