Biopsy of Skin: shows features suggestive of Leucocytoclastic Vasculitis.

1.Sjogren’s Syndrome

2.Hypokalemic Periodic Paralysis

3.Renal Tubular Acidosis

4.Leucocytoclastic Vasculitis

Quadriparesis reversed immediately after correction of Hypokalemia which includes infusion of KCl.. 2 correction of Inj. KCl was given 1 day apart.


•Hypokalemia was caused due to Renal Tubular Acidosis which was treated with Sodium Bicarbonate and diuretics. Tab. SODIUM BICARBONATE (SODAMINT) 2-2-2

•LCV is treated with oral steroids along with Methotrexate which modulates the immune system and reduces the intensity of the disease.

•Sjögren’s Syndrome was treated symptomatically with eye drops, moisturizing lotion, saliva substitutes and immunomodulators like HCQS.

Sjögren’s syndrome is divided into primary and secondary forms. The clinical hallmarks of Sjögren’s syndrome are keratoconjunctivitis sicca (dry eyes), xerostomia (dry mouth), and parotid gland swelling. Extraglandular features of primary Sjögren’s syndrome include fatigue, Raynaud’s phenomenon, polyarthralgia/arthritis, interstitial lung disease, neuropathy, and purpura. (1) 

Hypokalaemia Periodic Paralysis (HypoKPP) is a disease that usually occurs at adolescence. Men are more often affected because of decreased penetrance in women.  Attacks are often provoked by meals high in carbohydrates or sodium and may accompany rest following prolonged exercise.

Weakness usually affects proximal limb muscles more than distal. Ocular and bulbar muscles are less likely to be affected. Respiratory muscles are usually spared, but when they are involved, the condition may prove fatal. Weakness may take as long as 24 h to resolve. Life-threatening cardiac arrhythmias related to hypokalaemia may occur during attacks. A low serum potassium level during an attack, excluding secondary causes, establishes the diagnosis. (2) 

Leucocytoclastic Vasculitis is a type of cutaneous vasculitis (Immune Complex mediated Vasculitis) which usually presents as a palpable purpura, but a variety of other skin lesions may be found including pustules, vesicles, urticaria, and small ulcerations. (1)

Most cases of idiopathic cutaneous leukocytoclastic vasculitis are mild and resolve with supportive measures such as leg elevation, rest, compression stockings, and antihistamines. In more chronic or resistant cases, a 4-6 week tapering dose of corticosteroids can be used.  Rarely, immunosuppressive steroid-sparing agents such as methotrexate, azathioprine, mycophenolate mofetil, dapsone, cyclophosphamide, and intravenous immunoglobulin may be needed.
