Lupus and Kidney Damage: What You Should Know About Lupkynis for Active Nephritis
Introduction
Systemic lupus erythematosus, often called lupus, is a chronic autoimmune disease in which the immune system attacks healthy tissues. One of the most important organs it can affect is the kidney. When lupus involves the kidneys, the condition is called lupus nephritis, and it can lead to inflammation, protein loss in urine, reduced kidney function, and, if untreated, long-term kidney damage.1
How Does Lupus Affect the Kidneys?
In lupus, abnormal immune activity can lead to the formation of immune complexes that deposit in the kidneys and trigger inflammation. This inflammation can damage the tiny filtering units in the kidneys called glomeruli. As a result, protein may leak into the urine (proteinuria), blood may appear in the urine (haematuria), and kidney function may decline. Swelling and high blood pressure may also occur.1,2
What is Lupus Nephritis?
Lupus nephritis is the term used when lupus causes inflammation in the kidneys.1 Lupus nephritis can vary in severity from one person to another. Some forms may require more intensive treatment.3
Because the severity of kidney involvement may not always be clear from symptoms or laboratory findings alone, a kidney biopsy may be recommended to assess the extent of kidney damage and disease activity. The results can help your doctor make treatment decisions and understand the likely course of the disease.4,5
Why Active Lupus Nephritis Needs Early Medical Attention?
Lupus nephritis may have few symptoms in its early stages but can progress to chronic kidney disease within a few months if left untreated. This is why early diagnosis and timely treatment are important.3
The main goal of treatment is to help protect your kidneys and keep lupus nephritis under control. Lowering protein in the urine early – especially within the first 6-12 months of treatment – has been linked to better long-term outcomes, including a lower risk of flares and kidney failure.6
What is Lupkynis?
Lupkynis (voclosporin) is an oral medicine used to treat lupus nephritis. It belongs to a group of medicines called calcineurin inhibitors and is used along with other medicines to help control the abnormal immune activity that causes inflammation in the kidneys.7,8
Lupkynis works by inhibiting an enzyme called calcineurin. This can help reduce the activity and multiplication of cells involved in the immune response. It also helps stabilize specialized cells in the kidneys called podocytes, which are important for maintaining the kidney's filtering function. As a result, it can help reduce protein loss in the urine.7,8
How Does Lupkynis Fit into Lupus Nephritis Treatment?
Lupkynis is used as part of a combination treatment for lupus nephritis, along with medicines such as mycophenolate mofetil (MMF) and corticosteroids. When Lupkynis is added to these medicines, it can increase the chances of achieving complete remission, which means better control of the signs of active kidney disease.3,5
Treatment with Lupkynis has also been associated with reductions in proteinuria, an important sign of kidney involvement in lupus nephritis. These reductions were maintained with continued treatment in long-term follow-up.3,5
Why is Lupkynis Used with Other Medicines?
Lupus nephritis can require treatment with more than one medicine to help control the disease. Lupkynis is used in combination with other medicines, such as MMF, as part of an overall treatment plan. Combining medicines that work in different ways may help provide more comprehensive treatment for lupus nephritis.3
What Monitoring Is Needed During Treatment with Lupkynis?
When you are taking Lupkynis, your doctor will regularly check your kidney function and blood pressure. Your kidney function will be checked before starting treatment and monitored regularly during treatment using a measure called estimated glomerular filtration rate (eGFR), which shows how well your kidneys are filtering your blood. Blood pressure is also checked before treatment and monitored closely during the first month.7,8
Your doctor may also monitor your blood potassium levels and other parameters, depending on your individual risk factors. This monitoring helps identify changes in kidney function, blood pressure, or other potential side effects early and allows your doctor to adjust your treatment if needed.7,8
What are the Possible Side Effects?
Like other medicines that affect the immune system, Lupkynis can cause side effects. Some of the commonly reported side effects include changes in kidney function, increased blood pressure, diarrhoea, headache, and fatigue.7
Because Lupkynis affects the immune system, it can also increase the risk of infections. Talk to your doctor if you develop symptoms such as fever, chills, or a persistent cough.7
Your doctor will monitor your health during treatment and can advise you about any side effects or symptoms that need attention.
What Should You Keep in Mind During Treatment with Lupkynis?
Along with managing lupus nephritis, it is important to maintain a healthy lifestyle and keep certain health factors under control. This may include avoiding smoking, maintaining a healthy weight, and staying physically active. Regular monitoring and management of blood pressure, blood glucose, and cholesterol levels are also important.3,7
When taking Lupkynis, take it on an empty stomach, either 1 hour before or 2 hours after a meal. Tell your doctor before receiving any vaccines, as live vaccines may not be recommended during treatment. Protect your skin from excessive exposure to sunlight and ultraviolet light by wearing protective clothing and using sunscreen. You should also avoid grapefruit and grapefruit juice while taking Lupkynis.7
How Does Rx4u Support Access Through the Named Patient Program?
A Named Patient Program (NPP) is a pathway that may allow eligible patients to access medicines that are not routinely available in their country.8
Services such as Rx4u support patients and physicians access medicines through NPP. This can include assistance with required documentation, eligibility review, and coordination of communication with the treating specialist. You can discuss with your treatment options and access pathways with your physician to learn more.
Conclusion: Protecting Kidney Health with Specialist-Led Care
Lupus nephritis requires specialist-led care, with early diagnosis, biopsy-guided assessment, and timely treatment to help preserve kidney function and reduce the risk of long-term damage. Lupkynis is an option for the treatment of active lupus nephritis when used with background immunosuppression and appropriate monitoring. Regular communication with your healthcare team can help ensure that your condition and treatment are monitored closely.6-8 Services such as Rx4u can support access to this medicine through the NPP.
