Renal glycosuria is a rare condition in which the simple sugar glucose is excreted in the urine despite normal or low blood glucose levels. With normal kidney (renal) function, glucose is excreted in the urine only when there are abnormally elevated levels of glucose in the blood. However, in those with renal glycosuria, glucose is abnormally elevated in the urine due to improper functioning of the renal tubules, which are primary components of nephrons, the filtering units of the kidneys. Signs and symptoms
In most affected individuals, the condition causes no apparent symptoms (asymptomatic) or serious effects. When renal glycosuria occurs as an isolated finding with otherwise normal kidney function, the condition is thought to be inherited as an autosomal recessive trait. Genetics
It is associated with SLC5A2, coding the sodium-glucose cotransporter 2. Diagnosis
A doctor normally can diagnose renal glycosuria when a routine urine test (Urinalysis) detects glucose in the urine, while a blood test indicates that the blood glucose level is normal. Treatment
The cause of glycosuria determines whether the condition is chronic or acute. However, the presence of glucose in urine is not necessarily a serious or life-threatening condition.Managing diabetes, hyperthyroidism and regular kidney function tests can help in reducing excretion of sugars in urine.Drugs like dapagliflozin and canagliflozin have recently been approved for lowering blood sugar levels in patients with type 2 diabetes mellitus.

Other truths being actively revealed include data suggesting that the pathogen itself (i.e., chlamydia) might play an equally important role, or perhaps even more important, than the host with disease susceptibility; asymptomatic chlamydial infections might be a common cause of reactive arthritis and the two variants of reactive arthritis might respond differently to treatment in spite of the congruent clinical presentation. However, much about this syndrome remains shrouded in mystery. Recent data has been suggesting that Chlamydia-induced reactive arthritis might be a common condition that clinicians are simply failing to recognise. Therefore, an emphasis is placed on disease awareness since viable treatment options are emerging. Treatment

Balanitis circinata is one out of multiple manifestations of the reactive arthritis.Right now, topical corticosteroid therapy is the most commonly used treatment, and topical calcineurin inhibitors have also been used successfully. Newer tests on patients showed that a less harmful off-label topical treatment with the immunomodulator pimecrolimus or the immunosuppressant tacrolimus can prevent all visible symptoms of this disease. Since reactive arthritis cannot be healed as such, affected people are forced to a continuous topical treatment – otherwise they will again note first symptoms after three to four days without it.However, strong debates and controversies continue regarding the exact indications of immunomodulators like pimecrolimus and their duration of use in the absence of active controlled trials. A study released in 2015 (tested were 7,457 children with a total of 26,792 person-years) did not find any evidence that pimecrolimus could cause cancer. == References ==
