![]() ![]() ![]() The immunological analysis did not reveal any significant abnormalities.Ī renal ultrasound revealed grade II-III/IV pelvicalyceal dilatation of the left kidney and fluid collection in the left perirenal space (Figure 2). The urine sample resulted in: urine pH: 8 negative anion gap diuresis: 3200ml/24h calciuria: 137.7mg/24h hypocitraturia (citraturia <102mg/24h), and normal oxaluria. Upon arrival in the emergency room, she had: AHT: 103/71mm Hg, HR: 78 systoles, deep abdominal palpation produced pain in the left hypochondria and fossa, with positive left renal percussion.īlood analysis highlighted a pH of 7.18, bicarbonate at 12.4mmol/L with normal plasma anion gap, PCO 2 at 35mm Hg, K + at 3.3meqL, chlorine at 121 meq/l, creatinine at 0.62mg/dl, calcium at 8.3mg/dl, albumin at 3.3g/dl, and phosphorous at 3.6mg/dl. We reviewed the patient’s previous laboratory results and observed that she had hyperchloremic metabolic acidosis and hypokalaemia with persistently alkaline urine pH with several years’ evolution. She had a history of rhabdomyolysis secondary to severe hypokalaemia of an unknown cause, bilateral nephrocalcinosis, and nephrolithiasis (Figure 1). We treated a 28-year old pregnant woman (7 weeks gestation) that sought emergency treatment for intense weakness with vomiting and abdominal pain. Here we present the case report of a gestating mother (7 weeks) diagnosed with RTA. Early diagnosis can facilitate providing adequate treatment, which avoids potentially severe complications. Distal renal tubular acidosis (RTA) is a relatively uncommon tubulopathy that is characterised by hyperchloremic metabolic acidosis, hypokalaemia, elevated urine pH (>5.5), and a negative anion gap. ![]()
