Journal of Diabetes Investigation (JDI) Vol. 2, Issue 1: Monthly Review Summary
This issue of the Journal of Diabetes Investigation, Volume 2, Issue 1, highlights important advancements in understanding and managing diabetes and its complications. The reviewed articles offer insights into the complex nature of diabetic nerve damage and the potential for improved treatment strategies for type 2 diabetes.
A significant review article discusses recent progress in understanding and treating diabetic distal symmetrical polyneuropathy (DPN), a common form of nerve damage in people with diabetes. It reinforces the critical role of poor blood glucose control and other cardiovascular risk factors in its development. The article also sheds light on the mechanisms behind DPN, including nerve ischemia (reduced blood flow to nerves), and notes that painful forms of this neuropathy are often underdiagnosed and undertreated. It reviews current effective treatments such as alpha-lipoic acid and epalrestat, alongside other pain management approaches.
Another key study investigates the efficacy of pioglitazone in type 2 diabetes patients who are already on insulin but still have uncontrolled blood sugar. The findings suggest that adding pioglitazone to their regimen not only significantly improves blood glucose levels (measured by HbA1c) and reduces the need for insulin, but also shows promise in slowing down the progression of atherosclerosis, a hardening of the arteries that can lead to heart disease.
Overall, this issue underscores the importance of a comprehensive approach to diabetes care, focusing on tight blood sugar management, addressing nerve damage, and mitigating cardiovascular risks. For patients and their families, these studies offer valuable information for better diagnosis, more effective treatment options, and strategies to improve long-term health and quality of life.

Recent advances in the management of diabetic distal symmetrical polyneuropathy
Authors: Solomon Tesfaye
Research Objective: This comprehensive review aimed to summarize the latest developments in understanding, diagnosing, and managing diabetic distal symmetrical polyneuropathy (DPN) and its painful form, diabetic painful neuropathic pain (DPNP).
Main Findings:
- Poor blood glucose control and traditional cardiovascular risk factors are strongly linked to the development of DPN.
- New diagnostic criteria for DPN have been established by the International Expert Group on Diabetic Neuropathy.
- The underlying causes of DPN involve several metabolic problems, including hyperactivity of the polyol pathway, increased advanced glycation end-product formation, and oxidative stress. Strong evidence also points to nerve ischemia (reduced blood flow to nerves) as a key cause, with studies showing reduced nerve perfusion and oxygen levels in nerve tissue.
- Unfortunately, many promising compounds effective in animal models have not shown success in human trials. Currently, only the antioxidant alpha-lipoic acid and the aldose reductase inhibitor epalrestat are clinically proven and in use for human diabetic neuropathy.
- Diabetic painful neuropathic pain (DPNP) is estimated to affect 16% of the diabetic population, but it is frequently underdiagnosed and undertreated. Many patients never report their symptoms to a doctor or receive appropriate treatment.
- Pharmacological treatments for DPNP include tricyclic compounds, serotonin noradrenaline reuptake inhibitors (SNRIs), alpha-lipoic acid, anticonvulsants, opiates, membrane stabilizers, and topical capsaicin. Treatment plans should be tailored to individual patient needs and existing health conditions.
Clinical Significance: This review highlights the intricate nature of DPN/DPNP, emphasizing the critical role of both metabolic and vascular factors in its development. It underscores the urgent need for early and accurate diagnosis, as well as personalized treatment strategies, especially for painful neuropathy, which is often overlooked. The limited success of new drug development points to the ongoing challenges and the need for more effective therapies.
Key Points for Patients:
- Blood Sugar Control is Key: Keeping your blood sugar levels well-managed is crucial for preventing or slowing down nerve damage (neuropathy). Also, managing other health conditions like high blood pressure and cholesterol is important.
- Recognize Symptoms: Nerve damage can cause numbness, tingling, burning, or pain, especially in your feet and hands. If you experience any unusual sensations, it's vital to tell your doctor.
- Speak Up About Pain: Painful nerve damage is common but often goes unreported and untreated. Don't hesitate to discuss any pain you're experiencing with your healthcare team.
- Treatment Options Exist: There are medications and other strategies available to manage symptoms, particularly pain. Your doctor can help you find the best treatment plan, which may include specific drugs like alpha-lipoic acid.
Efficacy of pioglitazone on glycemic control and carotid intima‐media thickness in type 2 diabetes patients with inadequate insulin therapy
Authors: Eisuke Yasunari, Kageumi Takeno, Hideaki Funayama, Setsuko Tomioka, Motoyuki Tamaki, Yoshio Fujitani, Ryuzo Kawamori, Hirotaka Watada, Takahisa Hirose
Research Objective: This study aimed to investigate the effects of adding pioglitazone to existing insulin therapy on blood sugar control and the progression of atherosclerosis (hardening of the arteries) in patients with poorly controlled type 2 diabetes.
Methods: This was a prospective, randomized controlled trial involving 48 patients with type 2 diabetes whose blood sugar was not adequately controlled despite receiving insulin therapy. Participants were randomly divided into two groups: one group (n=22) received oral pioglitazone (titrated from 15-30 mg) in addition to their current medications, while the control group (n=26) continued their existing regimen without pioglitazone. Researchers monitored glycosylated hemoglobin (HbA1c), daily insulin doses, and carotid intima-media thickness (CIMT, a measure of artery wall thickness indicating atherosclerosis) using B-mode ultrasound.
Main Findings:
- The group receiving pioglitazone showed a significant decrease in HbA1c values by 1.13% on average, compared to a 0.55% decrease in the control group (P < 0.05), indicating better blood sugar control.
- The daily insulin dose decreased in the pioglitazone group by 0.04 units/kg/day, whereas it increased in the control group by 0.03 units/kg/day (P < 0.05). The number of insulin injections also decreased in the pioglitazone group.
- Carotid intima-media thickness, a marker for atherosclerosis, significantly decreased in the pioglitazone group at the end of the study compared to baseline, while no significant change was observed in the control group.
Clinical Significance: These findings suggest that for type 2 diabetes patients whose blood sugar remains poorly controlled despite insulin therapy, adding pioglitazone can significantly improve glycemic control. Furthermore, pioglitazone appears to have a beneficial effect on preventing the progression of atherosclerosis, which is a major risk factor for cardiovascular diseases like heart attack and stroke in people with diabetes. The potential to reduce insulin dosage and injection frequency could also improve patient convenience and adherence to treatment.
Key Points for Patients:
- Improved Blood Sugar Control: If you have type 2 diabetes and your blood sugar levels are not well-controlled even with insulin, your doctor might consider adding pioglitazone to your treatment plan. This study showed it can significantly lower your HbA1c (average blood sugar).
- Reduced Insulin Needs: Adding pioglitazone might allow your doctor to reduce your daily insulin dose or the number of injections you need, which can make managing your diabetes easier.
- Heart Health Benefits: Beyond blood sugar control, this medication may also help protect your arteries by slowing down the thickening and hardening of blood vessels (atherosclerosis), which can reduce your risk of heart attacks and strokes.
- Discuss with Your Doctor: Always talk to your healthcare provider about your treatment options. They can determine if pioglitazone is a suitable and safe addition to your diabetes management plan.
