Chronic kidney disease is a serious condition in which the kidneys gradually lose their ability to filter waste and extra fluid from the blood.
This disease affects millions of people worldwide and is especially common in people with type 2 diabetes. When the kidneys do not function properly, harmful substances build up in the body, increasing the risk of heart disease, stroke, and kidney failure.
Because kidney damage often develops slowly and without clear symptoms, early detection and treatment are very important.
One of the earliest warning signs of kidney damage is albuminuria, a condition in which a protein called albumin leaks into the urine. Healthy kidneys normally keep this protein in the bloodstream, so its presence in urine suggests that the kidney’s filtering system is damaged.
Higher levels of albumin in urine are linked to faster progression of kidney disease and a greater risk of heart problems. Doctors therefore use this measure to monitor how well treatments are working.
A new international study has found that using two medications together may protect the kidneys more effectively than using either drug alone in patients with chronic kidney disease and type 2 diabetes. The research, known as the CONFIDENCE trial, was presented at a major medical conference and published in a leading medical journal.
The study tested two drugs that are already known to help people with kidney disease. One drug, finerenone, reduces inflammation and scarring in the kidneys by blocking certain hormone signals that can damage kidney tissue.
The other drug, empagliflozin, belongs to a group of medicines that lower blood sugar and also help protect the kidneys and heart. Doctors have been using these medications separately, but researchers wanted to see whether starting both at the same time would provide extra benefits.
More than 800 adults with chronic kidney disease and type 2 diabetes took part in the trial. All participants were already receiving standard treatment to control blood pressure and protect kidney function. They were divided into three groups.
One group received empagliflozin alone, another received finerenone alone, and the third group received both drugs together. The participants came from many countries, making the results relevant to a wide range of patients.
After six months, the group taking both medications showed the greatest improvement. Their urine protein levels dropped by about half compared with the start of the study.
This reduction was significantly larger than the improvements seen in the groups taking only one drug. A decrease in albuminuria is important because it is linked to slower kidney damage and better long-term health outcomes.
The combination treatment was also generally safe. Researchers monitored participants for possible side effects such as low blood pressure, kidney problems, or high potassium levels.
Serious complications were uncommon, and most patients tolerated the treatment well. This suggests that using both drugs together could be a practical option for many patients under medical supervision.
Experts believe these findings may change how doctors treat kidney disease in people with diabetes. Traditionally, treatments are added one at a time, but this study suggests that starting with a combination approach may provide stronger protection earlier.
Similar strategies are already used for conditions such as high blood pressure and heart failure, where using multiple medications together has improved outcomes.
In reviewing the study, the results provide strong evidence that targeting kidney disease through different biological pathways at the same time can produce greater benefits than single-drug therapy. The large number of participants and the careful design of the trial increase confidence in the findings.
However, longer follow-up is needed to determine whether the reduction in urine protein will translate into fewer cases of kidney failure or cardiovascular events over many years. Researchers will continue monitoring patients to answer these important questions.
Overall, the study offers hope for people living with chronic kidney disease and diabetes, conditions that often occur together and significantly raise the risk of serious health complications. Early and effective treatment could slow disease progression and improve quality of life.
Patients should always consult their doctors before making any changes to medication, but the findings suggest that combination therapy may become an important tool in protecting kidney health in the future.
