Distal renal tubular acidosis in Sjögren's syndrome.

Interstitial nephritis and immune complex-mediated glomerulonephritis are the two common renal manifestations of primary Sjögren's syndrome (SS). Here, we discuss three cases of primary SS where presenting manifestation was distal renal tubular acidosis. The possibility of an underlying autoimmune disorder should be considered in a patient presenting with distal tubular acidosis or recurrent hypokalemic periodic paralysis as treatment of primary disease improves the outcome of illness.

Transient Distal Renal Tubular Acidosis in Organophosphate Poisoning.

Renal complications due to organophosphate poisoning are very rare. We are presenting a unique case of transient distal renal tubular acidosis due to organophosphate poisoning, which to the best of our knowledge is the first of its kind. An elderly female after deliberate self-harm with ingestion of chlorpyrifos had multiple ventricular arrhythmias due to hypokalemia secondary to distal renal tubular acidosis which improved completely after treatment.

Idiopathic granulomatous mastitis with erythema nodosum and polyarthritis.

A 25 year-old woman presented with a painful mass in the left breast, polyarthritis and erythema nodosum. Fine needle aspiration cytology led to a diagnosis of granulomatous mastitis. Oral prednisolone rapidly improved the arthritis and the erythema nodosum.
