Ten normal healthy male subjects between 20-30 years of age were initially examined at Delhi (200 m) and thereafter air-lifted to an altitude of 3,500 m. Excretion of sodium, potassium and chloride in urine and their plasma level were determined at sea level (SL) and daily at high altitude (HA) for 4 d. At HA, four subjects developed high-altitude pulmonary edema (HAPE), four remained normal, and two suffered from acute mountain sickness. The results on normals and HAPE are presented. There was increased excretion of potassium at HA in both groups resulting in reduction of plasma level. The sodium and chloride excretion was also increased in normals at HA irrespective of urine volume. In HAPE cases, the sodium and chloride excretion was related to urine output. With the retention of fluid, the excretion of these ions in urine was diminished without a parallel change in plasma levels.

Epidemic dropsy results from the consumption of edible oils adulterated with Argemone mexicana oil by unscrupulous traders. Twenty consecutive 'in-door' patients of dropsy were intensively studied during the recent Delhi epidemic. Samples of edible oil used by them, their urine and their serum samples tested positive for sanguinarine on thin layer chromatography. The illness starts as a gastro-enteric illness followed by oliguria and pedal oedema. The following are often observed: cutaneous erythema with blanching and tenderness on pressure; violacious pigmentation of the skin; shortness of breath with orthopnoea; right-sided heart failure with normal left ventricle (LV) functions; as well as severe anaemia and hypoalbuminaemia. Renal function tests showed: bland urinary sediments; decreased glomerular filtration rate (GFR); mild to moderate azotaemia; acute tubular necrosis; patchy pneumonitis; moderate hypoxia with respiratory alkalosis; and restrictive ventilatory defects on blood gas analysis; and spirometry suggestive of interstitial pulmonary oedema of non-cardiogenic origin. 99mTc colloid sulphur liver scans showed colloid shift. There was marked dilatation and proliferation of dermal capillaries in the absence of significant inflammation in the biopsy specimens. Toxic alkaloids of Argemone mexicana oil induce widespread capillary dilatation and permeability causing leakage of protein rich plasma into the interstitial tissues of various organs. A hypovolaemic state is thus induced producing renal hypoperfusion which may progress to acute tubular necrosis. Interstitial fluid in alveoli causes restrictive ventilatory dysfunction with hypertension and right-sided failure with well-preserved LV function. The hepatic venous congestion induces Kupffer's cell dysfunction, which results in colloid shift on a radionuclide liver scan.

Pulmonary functions were performed in thirteen patients with epidemic dropsy. The epidemic occurred in Delhi in 1998 during which 102 patients with epidemic dropsy reported to our medical unit. Other investigations included chest radiograph, ECG, liver and renal function tests. There was a restrictive ventilatory defect with diminution of diffusion capacity for carbon monoxide in these patients. Echocardiogram was done in seven of these patients and was normal. The cause of breathlessness and restrictive ventilatory defect is likely to be non-cardiogenic pulmonary oedema.
