At Klinik Teoh – Family Medicine Specialist Clinic, we strive to adopt innovative medical treatments to help patients with chronic illnesses achieve better health outcomes. One such therapy showing great promise is mesenchymal stem cell (MSC) therapy, particularly for patients suffering from microalbuminuria. This article explores how MSC therapy works, its benefits, and how it offers hope for patients with difficult-to-manage conditions, supported by a real-world case from our clinic.

What is Microalbuminuria and Why is It Important?
Microalbuminuria refers to the presence of small amounts of albumin in the urine, typically between 30 and 300 mg per day. Under normal conditions, the kidneys filter out waste products from the blood while retaining essential proteins like albumin. However, when the glomeruli—the kidney’s filtering units—are damaged, small amounts of albumin leak into the urine.
Though the amount of leaked protein may seem minimal, microalbuminuria is often a precursor to more severe kidney damage and serves as an early indicator of chronic kidney disease (CKD). This condition is common in patients with:
Diabetes
Hypertension
Autoimmune diseases (e.g., lupus, Goodpasture Syndrome)
Chronic kidney disease
If left untreated, microalbuminuria can progress to overt proteinuria, where larger amounts of protein leak into the urine. Over time, this can impair kidney function, increasing the risk of end-stage renal disease (ESRD). Additionally, microalbuminuria is associated with a higher risk of cardiovascular complications such as heart attacks and strokes, making it essential to manage the condition early.

Case Study: MSC Therapy for Goodpasture Syndrome and Microalbuminuria
One of our patients, a 45-year-old female diagnosed with Goodpasture Syndrome, presented with severe microalbuminuria. Goodpasture Syndrome is an autoimmune disorder that attacks the kidneys and lungs, leading to progressive renal damage. The patient’s urine microalbumin levels were alarmingly high:
9-6-24: 2487.4 mg/L
26-6-24: Received 100 million MSCs intravenously as part of her treatment plan.
26-7-24: 1129.8 mg/L
27-10-24: 954.9 mg/L
Following MSC therapy, her urine microalbumin levels steadily decreased, with more than a 60% reduction in just four months. This case demonstrates the potential of MSC therapy to halt the progression of renal damage and improve kidney function, even in complex autoimmune diseases.

How MSC Therapy Helps Reduce Microalbuminuria
MSC therapy works by delivering multipotent stem cells capable of repairing tissue, modulating immune responses, and reducing inflammation. Below are the key mechanisms through which MSC therapy helps manage microalbuminuria:
1. Anti-Inflammatory Effects:
Chronic inflammation plays a significant role in the progression of kidney damage. MSCs secrete anti-inflammatory cytokines and growth factors, which help reduce inflammation in the kidneys, protecting the glomeruli from further injury.
2. Tissue Repair and Regeneration:
MSCs promote the regeneration of damaged glomeruli, restoring the kidneys’ ability to filter waste effectively while retaining essential proteins such as albumin.
3. Immune System Modulation:
In autoimmune diseases like Goodpasture Syndrome, the immune system attacks healthy tissues, including the kidneys. MSCs regulate the immune response, preventing further immune-mediated damage and creating an environment conducive to healing.
4. Angiogenesis and Fibrosis Reduction:
MSCs stimulate angiogenesis—the formation of new blood vessels—which improves blood flow to the kidneys. At the same time, they help reduce fibrosis (scar tissue formation) in the kidney tissue, enhancing renal function over time.

The Importance of Early Treatment for Microalbuminuria
Treating microalbuminuria early is critical because it serves as a warning sign for both renal deterioration and cardiovascular risks. Addressing microalbuminuria with innovative therapies like MSCs can prevent progression to more severe kidney conditions such as overt proteinuria or end-stage renal disease (ESRD). Moreover, by reducing protein leakage, MSC therapy helps improve the overall health of the kidneys and reduces the burden of chronic diseases.
Patients with chronic kidney disease, diabetes, or autoimmune conditions often struggle with conventional treatments that may not be sufficient to reverse kidney damage. MSC therapy offers a promising alternative by promoting tissue repair and immune balance while reducing inflammation and fibrosis. The results from our patient’s case show that MSC therapy can bring significant improvements, even in complicated cases like Goodpasture Syndrome.

What Do Clinical Studies Say About MSC Therapy and Kidney Health?
Emerging clinical evidence supports the use of MSC therapy for kidney diseases, including microalbuminuria. Here are some key studies:
1. Luo, C., Zhang, F., Zhang, Q., & Xu, Y. (2021).
Mesenchymal Stem Cell Therapy in Kidney Disease: Mechanisms and Clinical Evidence. Journal of Cellular and Molecular Medicine, 25(4), 1947-1957.
This study highlights the immunomodulatory and regenerative properties of MSCs in managing chronic kidney disease, showing improvements in glomerular function and reduced inflammation.
2. Morigi, M., Imberti, B., Zoja, C., et al. (2008).
Mesenchymal Stem Cells Improve Glomerular Function in Acute Kidney Injury Through Paracrine Actions. Journal of the American Society of Nephrology, 19(11), 2033-2044.
This research demonstrates that MSCs enhance kidney function by secreting protective factors that promote healing and reduce inflammation.
3. Kunter, U., Rong, S., & Djuric, Z. (2006).
Transplanted Mesenchymal Stem Cells Prevent Progression of Glomerular Injury in Chronic Kidney Disease. Kidney International, 70(7), 1234-1240.
This study shows that MSCs prevent the progression of kidney disease by reducing fibrosis and restoring glomerular health, leading to improved renal function.
