No, there is no cure for Sjogren's syndrome.

As a treatment option indicated for dry eye due to this syndrome is Restasis - Cyclosporine eye drops to manage underlying inflammatory process.

It depends on our understanding for cure is it eradication of the disease  if so Im afraid we are far from achieving that goal

Since it is a progressive autoimmune disease there is, at present, no known cure. About a third of patients may also have other systemic complaints; and a small number of cases may develop malignant lymphoma.

It may occur alone or in association with other autoimmune rheumatic diseases. In most patients, the primary syndrome runs a slow and benign course. The initial manifestations can be mucosal or nonspecific dryness, and 8–10 years may elapse from the initial symptoms to full-blown disease.

Treatment of Sjögren’s syndrome is aimed at symptomatic relief and limiting the damaging local effects of keratoconjunctivitis sicca by substituting or simulating the missing secretions. To replace deficient tears, there are several ophthalmic preparations (artificial tears 0.5% methylcellulose). If corneal ulcerations are present, eye patching and boric acid ointments are recommended.

Certain drugs may decrease lacrimal and salivary secretion (diuretics, antihypertensive drugs, anticholinergics, and antidepressants). Avoid them.

For xerostomia the best replacement is water. Propionic acid gels may be used to treat vaginal dryness. To stimulate secretions, pilocarpine (5 mg thrice daily) orally appears to improve sicca manifestations and well tolerated.

Sir Sjogrens is an auto immune disorder. Which means that the body finds its own cells not friendly.

The treatment is aimed to decrease the disability rather than cure. Since the origin of the disease is genetic the chances of cure is remote but relief is tremoundrous.

What is the treatment for Sjögren's syndrome? Will dietarychanges improve Sjögren's syndrome symptoms and signs?

The treatment of patients with Sjögren's syndrome is directed toward the particular areas of the body that are involved andprevention of complications such as infection. There is no cure for Sjögren's syndrome.

Dryness of the eyes can be helped by artificial tears, using eye-lubricant ointments at night, and minimizing the use of hair dryers. When dryness becomes more significant, the ophthalmologist can plug the tear duct closed so that tears cover the eye longer. Cyclosporine eye drops (Restasis) are approved medicated eyedrops that can reduce the inflammation of the tear glands, thereby improving their function. Signs of eye infection (conjunctivitis), such as pus or excessive redness or pain, should be evaluated by the doctor. Dietary addition offlaxseed oil may also benefit eye dryness.Vitamin D supplementation may be beneficial, especially in those who have insufficient vitamin D blood levels.

The dry mouth can be helped by drinking plenty of fluids, humidifying air, and good dental care to avoid dental decay. The glands can be stimulated to produce saliva by sucking on sugarless lemon drops orglycerin swabs. Additional treatments for the symptom of dry mouth are prescription medications that are saliva stimulants, such as pilocarpine (Salagen) andcevimeline (Evoxac). These medications should be avoided by people with certain heart diseases, asthma, or glaucoma. Artificial saliva preparations can ease many of the problems associated with dry mouth. Many of these types of agents are available as over-the-counter products, includingtoothpaste, gum, and mouthwash (Biotene). Numoisyn Liquid and lozenges are also available for the treatment of dry mouth. Vitamin E oil has been used with some success. Infections of the mouth and teeth should be addressed as early as possible in order to avoid more severe complications. Diligent dental care is very important. Moist, warm compresses can be massaged onto the parotid glands to help relieve swelling and pain.

Saltwater (saline) nasal sprays can help dryness in the passages of the nose. Vaginal lubricant should be considered for sexual intercourse if  vaginal dryness if a problem.

Hydroxychloroquine (Plaquenil) has been helpful for some manifestations of Sjögren's syndrome, particularly fatigue, muscle, and joint pains. Serious complications of Sjögren's syndrome, such as vasculitis, can require immune-suppression medications, including cortisone (prednisone and others) and/or azathioprine (Imuran) or cyclophosphamide (Cytoxan).

Infections, which can complicate Sjögren's syndrome, are addressed with appropriate antibiotics. Cancer of the lymph nodes (lymphoma), a rare complication of Sjögren's syndrome, is treated independently.

An interesting communication:

Thu, Jan 21, 2016 at 3:40 PM I received a mail from Dr Vandana.

I am copying her mail here for kind information of RG readers.

Dear Dr Sharma ,I read your question and I am happy  to share with you that

I was a sufferer of Sjogrens syndrome for a couple of years although 

diagnosis was confirmed in 2013 with modern techniques  as the symptoms

aggravated so much that it was difficult to live with them .As soon as

confirmation was there without wasting more time  I being an Ayurvedic practitioner 

and knowing that this traditional system of medicine would certainly evolve a solution

for a healthy, harmonious comfortable life as its holistic approach to a disease involving mind , body and spirit provides broader frame work to cure any ailment i cured mine and as i am leading a comfortable life .....no more artificial tears, no more lozenges every time, no more water bottle beside me  to quench the never quenched thirst  before, No medication to relieve myalgia  as I can walk six kms at a stretch ,

climb and come down stairs comfortably , no more skin infections, very less moisturiser for skin .....

I cured myself with my own specialisation 

I would like to provide free consultation to the patients who would send me their recent blood reports which confirmed the disease and their recent pics if possible. on my email vandana.pathak31 at gmail.com.

Infact i have recently presented my own case study with cure in an international conference on inner peace held

at Faridabad DAV college Haryana, India.

Dear Prof. Ravi K. Sharma,

If you have discovered (or invented) a cure (or more effective manner of relieving symptoms) for this disorder please bring it out in public domain after patenting the discovery if you want; but let the suffering be over for those few who suffer from this disorder. 

Since you are in CDRL it will be possible to get government and departmental help as well for patenting the product (or treatment) at the earliest.

Dear Dr Vandana

Very glad that you have been free from Dry eyes syndrome. or Sjogrens syndrome. It is a good science no doubt that Ayurveda has stood the test of time and will continue to do so.

understanding nature will definitely help us understand ourselves

coining the term from Fritjoph Capra, most of our ailment and diseases are from social pathology as our bodies are already given with self healing mechanism. Taking a networked systemic view of life thus will widen scope of applying concepts of Ayurveda and many other ancient traditions. I think any new application or idea that is proven to give positive outcome shall be shared as much as possible though our present socio-economic system do influence us take precautionary measures first to protect and ensure recognition of our innovation and ideas and monetary benefits. So, sad though

Sjogren's syndrome

Treatments and drugs

By Mayo Clinic Staff

Many people can manage the dry eye and dry mouth associated with Sjogren's syndrome by using over-the-counter eyedrops and sipping water more frequently. But some people may need prescription medications, or even surgery.

Medications

Depending on your symptoms, your doctor may suggest medications that:

Increase production of saliva. Drugs such as pilocarpine (Salagen) and cevimeline (Evoxac) can increase the production of saliva, and sometimes tears. Side effects may include sweating, abdominal pain, flushing and increased urination.

Address specific complications. If you develop arthritis symptoms, you may benefit from nonsteroidal anti-inflammatory drugs (NSAIDs) or other arthritis medications. Prescription eyedrops may be needed if over-the-counter drops aren't helpful. Yeast infections in the mouth should be treated with antifungal medications.

Treat systemwide symptoms. Hydroxychloroquine (Plaquenil), a drug designed to treat malaria, is often helpful in treating Sjogren's syndrome. Drugs that suppress the immune system, such as methotrexate, also may be prescribed.

Surgery

To relieve dry eyes, you may consider undergoing a minor surgical procedure to seal the tear ducts that drain tears from your eyes (punctal occlusion). Collagen or silicone plugs are inserted into the ducts for a temporary closure. Collagen plugs eventually dissolve, but silicone plugs stay in place until they fall out or are removed. Alternatively, your doctor may use a laser to permanently seal your tear ducts.
