INFANTILE METHÆMOGLOBINÆMIA FROM DRINKING-WATER CYANOSIS is usually produced by reduced haemoglobin in the subpapillary venous plexuses of the skin,l but when it occurs without cardiac or pulmonary disease the presence of methæmoglobin or sulphaemoglobin in the blood must be considered. Since 1945 reports have been appearing in the North American p2ediatric and public-health journals of a cyanotic syndrome in infants due to methaemoglobinsemia. This condition is caused by the ingestion of water derived from rural wells and containing more than 10-20 parts per million of nitrate ions, a concentration which Comly 2 looks upon as the maximum for waters which can safely be used for infant feeding. The nitrate ion is transformed by intes- tinal bacteria into nitrite and this is absorbed and converts some of the circulating haemoglobin into met- haemoglobin. The nitrates which find their wayinto the well water are formed by the action of soil bacteria on nitrogen compounds present in fertile humus. The wells are usually rather shallow and inefficiently lined. Waters containing large amounts of nitrate are reported by Weart 3 from various areas of the United States, Canada, England, and Belgium, and Weart has found no correla- tion between the nitrate content of well waters and their contamination with coliform bacteria. That nitrates can be responsible for methaemoglobin- semia has been known since the introduction of bismuth subnitrate in radiology. Death has been reported 4 after the administration of bismuth subnitrate for the treat- ment of diarrhoea in a young infant. The nitrates share their property of the intracorpuscular production of methæmoglobin with coal-tar derivatives, such as are used in the manufacture of aniline dyes and explosives, and with various drugs such as acetanilide, antipyrin, phenacetin, potassium chlorate, and sulphonamides. Extracorpuscular methæmoglobinæmia is found in phenylhydrazine poisoning and in severe infections (01. welchii). Some of these drugs may cause sulphaemo- globin2emia if an excess of sulphide is present in the gastro-intestinal tract. In " enterogenous cyanosis " the abnormal pigment is found in the red blood-cells even if no drug has been taken.5 It is suggested that this condi- tion is due to excessive nitrate production in the gastro- intestinal tract. There are a few cases on record of idiopathic familial methæmoglobinæmia with cyanosis, possibly due to a congenital metabolic error 6; these cases respond to large doses of ascorbic acid by mouth. Nitrate methæmoglobinæmia is much more common in infants than in adults. Of the various possible reasons for this, the relatively large intake of water in infancy is probably the most important ; others are the presence of smaller amounts of oxidisable haemoglobin in the infant’s blood ; the more ready absorption of nitrites in the infant’s gut and possibly a larger formation of nitrites due to differences in bacterial flora ; and poor elimination by the immature infantile kidney. Ascorbic acid in the blood may counteract the action of nitrites on haemoglobin, and depletion of ascorbic acid may 1. Lancet, 1947, ii, 431. 2. Comly, H. H. J. Amer. med. Ass., 1945, 129, 112. 3.
