A Cross-sectional Survey of Patients with Suspected Diabetic Peripheral Neuropathic Pain in Japan.

ABSTRACT: Objective The burden of diabetic peripheral neuropathic pain (DPNP) is poorly understood. The present study reported on the current status of DPNP in Japan, to improve our understanding of this condition among healthcare providers and inform future clinical research on its prevalence, diagnosis, and management. Methods A cross-sectional, observational study (UMIN000037023) was conducted via a web-based survey. The primary endpoints were the frequency of patients with bilateral foot symptoms, consulting a doctor, understanding DPNP, and reporting problems in daily life, as well as the treatment awareness of patients. Patients Adults ?20 years old who were registered in the Rakuten Insight Disease Panel and receiving anti-diabetic therapy in Japan were included. Results Bilateral foot pain symptoms were reported by 1,768/7,754 (22.8%) respondents, most commonly intense numbness (13.0%). Of those with symptoms, 55.3% consulted a doctor; the most common reason for not seeking consultation was feeling that symptoms were insufficiently severe to bother their doctor (89.4%). Nearly 60% reported understanding the causes of their symptoms, with diabetes-associated neurologic deficits (58.8%) most commonly identified. About one-quarter reported daily life problems, including an inability to walk for long periods (58.3%) and feeling anxious (58.1%). Treatment awareness was reported by 18.2%; oral medications were commonly recognized (64.6%). Conclusion In Japan, 22.8% of patients with diabetes have bilateral foot pain symptoms; some experience problems in their daily life without understanding the causes of their symptoms. This supports the importance of actions to increase awareness and minimize DPNP-associated impairment of daily life in patients with diabetes.

Project description:PurposeDuloxetine and pregabalin are recommended as first-line treatments for diabetic peripheral neuropathic pain (DPNP). However, studies have not reported a direct comparison between duloxetine and pregabalin. We conducted a postmarketing, randomized, double-blind study to assess the noninferiority of duloxetine compared with pregabalin after 12 weeks of treatment in adult patients with DPNP in Japan (NCT02417935).Patients and methodsPatients (N = 303) with distal symmetrical DPNP were randomized to and were administered duloxetine (40-60 mg/day) or pregabalin (300-600 mg/day). The primary endpoint was the change from baseline in weekly mean of the 24-hour average pain score (numeric rating scale [NRS]). Noninferiority of duloxetine compared with pregabalin was assessed with the primary endpoint at week 12. Secondary measures, including night pain and worst pain, Brief Pain Inventory-Severity and Interference rating short form (BPI-SF), Clinical Global Impression of Improvement (CGI-I), Patient Global Impression of Improvement (PGI-I), and Neuropathic Pain Symptom Inventory (NPSI), health outcome measures (EuroQol 5-Dimension index and VAS), and safety were also assessed.ResultsFor the 24-hour NRS average pain score, the difference between the duloxetine and pregabalin groups was 0.072 (95% CI: - 0.295, 0.439), and the upper bound of the 95% CI (0.439) did not exceed the predefined noninferiority margin (0.51), at the end of the study period. For secondary outcome measures (night pain, worst pain, BPI-SF, CGI-I, PGI-I, NPSI) and health outcome measures, both the duloxetine and pregabalin treatment groups showed an improvement from baseline with no significant between-group difference. Duloxetine and pregabalin were well tolerated and the safety profiles were consistent with previously reported results.ConclusionThis study demonstrated the noninferior efficacy of duloxetine compared with pregabalin in the treatment of adult patients with DPNP. The safety analyses showed an acceptable tolerability based on safety profiles of duloxetine and pregabalin.

Project description:PurposeChronic pain and migraines often go untreated despite patient- and economic-related burdens (e.g., impaired quality of life and productivity). Understanding the reasons for non-treatment is important to enable interventions aimed at improving care-seeking behaviors. However, reports on disease-specific justifications for nontreatment in Japan are limited. We aimed to determine the barriers to healthcare access in untreated patients with chronic pain or migraines.Patients and methodsThis was a non-interventional, cross-sectional, internet questionnaire survey of patients with chronic pain or migraines. The primary endpoint was to identify the reasons for untreated chronic pain or migraines. Secondary endpoints included factors associated with healthcare access, including patient background, patient-reported outcomes, and awareness of generic or authorized generic drugs (AG).ResultsWe surveyed 1,089 patients with chronic pain [605 (55.6%) untreated] and 932 patients with migraines [695 (74.6%) untreated] in 2021. The main reasons for not seeking treatment for chronic pain was "my pain is tolerable" and for migraine, "I can manage my pain with over-the-counter drugs." Background factors significantly associated with untreated chronic pain were younger age, less time required to access the nearest medical institution, less pain, higher activities of daily living (ADL) scores, and lower awareness of generic drugs and AG. Among patients with migraine, notable characteristics included being female, having shorter travel times to the nearest medical facility, residing in municipalities with populations under 50,000, experiencing moderate to severe pain, having higher ADL scores, and displaying lower awareness of AG. The AG awareness rate was 2-fold higher in treated patients than in untreated patients.ConclusionEducating patients regarding the risks associated with pain and its underlying causes, availability of inexpensive treatment options, and location of appropriate treatment facilities may increase treatment rates.
