Spinal Osteoarthritis as a Cause of Chronic Low Back Pain

Injectable Alflutop® (the bioactive concentrate from small sea fish (BCSSF)) belongs to the pharmacological group of symptomatic slow-acting drugs for osteoarthritis. This drug has been widely used in our country for 25 years. During this time, 37 of its clinical trials (n=3676) have been conducted in Russia and post-Soviet countries, mainly in patients with knee osteoarthritis (OA) and nonspecific back pain. These are mainly open-label trials, a major portion of which has been performed at the good methodological level, by using active control and up-to-date methods to assess treatment results. Two works are double-blind placebo-controlled trials (DBPCTs) conducted in compliance with the modern requirements of evidence-based medicine – this is an evaluation of the efficacy of BCSSF in knee OA and vertebrogenic lumbar ischialgia. All the trials have shown a good therapeutic potential of BCSSF: on the average, after the cycle use of the agent, there is a 40–60% decrease in pain intensity as compared to the baseline level. A two-year DBPCT of the efficacy of BCSSF in knee OA has also confirmed that the concentrate has a structure-modifying effect. At the same time, all the trials have demonstrated that BCSSF is well tolerated and very rarely causes adverse reactions that require discontinuation of treatment.

Non-steroidal anti-inflammatory drugs (NSAIDs) are the primary means of managing chronic osteoarthritis (OA) pain. The choice of NSAIDs is based on an analysis of the risk of adverse reactions (ARs). Objective: to evaluate the efficacy and safety of long-term use of NSAIDs for pain control in patients with OA in real clinical practice.Patients and methods. To assess the results of long-term use of NSAIDs in OA, a 12-month observational non-interventional study was conducted. It included 611 patients with knee, hip and generalized OA, and nonspecific back pain associated with OA of the facet joints. All patients were prescribed aceclofenac (Aertal®) 200 mg/day. The patients' condition was assessed 2 weeks, 3, 6, 9 and 12 months after the start of therapy. The following parameters were determined: the intensity of pain during movement and the general health assessment (GA) according to the visual analogue scale (VAS, 10 cm); pain intensity according to the Likert verbal rating scale (VRS) (0–4); the number of patients with a pain reduction of ≥50% from baseline; patients' assessment of the result of therapy according to Likert VRS (1–5). The development of ARs was recorded at each visit.Results and discussion. By month 12, 46.8% of patients had dropped out of observation. In patients who continued the study, the average severity of pain according to the VAS at baseline, after 2 weeks, 3, 6, 9 and 12 months was: 6.5±1.2; 4.8±1.4; 3.2±1.4; 2.6±1.4; 2.2±1.1; 1.4±1.1 cm, respectively (significant differences compared to the baseline for all points – p<0.05). The same differences were obtained in GA assessment.Within the indicated time frame, the number of patients with moderate / severe pain (on the Likert scale) decreased from 77.8 to 24.9; 2.9; 2.3; 0.9 and 0%, respectively. The number of patients with a pain reduction of ≥50% from baseline was 12.0; 65.1; 81.0; 88.5 and 84.0%, respectively. A good or excellent assessment of treatment results after 2 weeks was given by 63.3% of patients, and after 12 months – by 95.6%. ARs were observed in about 30% of patients, mainly mild or moderate dyspepsia (in 11.1–23.3%) and arterial hypertension (in 7.1–10.9%). No serious ARs were registered.Conclusion. Aceclofenac is an effective and relatively safe drug for the long-term management of chronic pain in OA.

Chronic back pain as a spinal osteoarthritis manifestation: rationale and practice of symptomatic slow acting drugs for osteoarthritis use

Chronic non-specific back pain (CNBP) is the most common pathology of the musculoskeletal system, affecting from 10 to 60% of the adult population in the world, causing severe suffering, disability and a significant deterioration in the quality of life. Osteoarthritis (OA) should be considered as one of the main reasons of the development of CNBP – inflammatory and degenerative changes in the facet and sacroiliac joints, as well as the spinal column itself (in particular, osteitis of the Modic 1 type). Spinal OA is accompanied by biomechanical disturbances, nociplastic (peripheral and central sensitization) and psycho-emotional changes that form a complete picture and various CNBP phenotypes.Recognizing the leading role of OA as the cause of CNBP, it is advisable to use the same therapeutic approaches in this syndrome as in OA of peripheral joints. In particular, it is necessary to consider the use of symptomatic slow acting drugs for osteoarthritis (SYSADOA) in CNBP as the main pathogenetic therapy.Alflutop is one of the most popular parenteral SYSADOA widely used in Russian practice. This drug has a good evidence base: this review presents data from 12 clinical trials of Alflutop in CNBP (n=1479), which confirmed its efficacy and safety.
