VITAMIN K AND THE NEWBORN your timely editorial (April 8, p. 755) controvitamin K and the newborn is likely to continue. The basis for disagreement is really the criteria for diagnosis of vitamin-K deficiency. Some workers, such as van Doorm, Muller, and Henkerl require demonstration of abnormal prothrombin in order to differentiate vitamin-K deficiency from failure of synthesis of factors n, vu, rx, and x. A compound designated as P.I.V.K.A.-II (protein induced by vitamin-K absence analogous to factor n) or descarboxyprothrombin has been unequivocally demonstrated in human and bovine plasma after the administration of coumarin compounds.2-’ As I pointed out earlier6 there are clear differences between the effects of coumarin drugs and those of vitamin-K deficiency. In such circumstances it is not unlikely that there would also be differences in the effects of venom from Echis carinatus or of staphylocoagulase, and even in the results of crossed immunoelectrophoresis. Testing of cord blood and of samples obtained more than 72 h postnatally is not ideal for demonstration of vitamin-K deficiency. In either period most babies will not show a clear-cut deficiency. The possibility that other reasons may be responsible for failure to demonstrate abnormal prothrombin in newborns cannot be excluded. Regardless of the explanation, it seems premature to equate such abnormal prothrombin with vitamin-K deficiency. We have differentiated deficiency from failure of synthesis of clotting factors by the corrective effect of the vitamin on characteristic coagulation defects.’-9 These have included deficiences of factors 11, vn, ix, and x and non-specific tests such as the one-stage prothrombin, the plasma recalcification, and the partial thromboplastin time, as well as the thromboplastic activity of serum. In many of our studies we selected sub-

jects by screening one-stage prothrombin-times in groups of ten to twenty babies 6-24 h after birth. Only those with less than 40% activity were investigated further. As the table shows, microgram doses of vitamin K produced a marked improvement in 4 h. Controls which failed to receive vitamin K never showed any significant correction in that short period of time. These results have been obtained with striking consistency. Babies with true hasmorrhagic disease of the newborn’O," have very severe alterations of coagulation following the abovementioned pattern. In these cases the bleeding tendency and the results of hxmostatic tests are also rapidly improved by administration of the vitamin. Such spectacular effects, both

clinically and in laboratory tests, seem wholly convincing. By contrast, failure of synthesis is not modified by vitamin-K administration.

NON-CŒLIAC GLUTEN SENSITIVITY?

SIR,-Further to the letter on food allergy by Professor Dickerson and colleagues (April 8, p. 773) we would like to report the case of a 43-year-old woman who presented in January, 1974, with a 4-month history of loose motions, three times a day with no blood or mucus. The diarrhoea was accompanied initially by periumbilical colic, which recurred intermittently, and abdominal distension, but she had not lost weight and had retained her appetite. She had been taking tetracycline for 6 years for acne conglobata; she smoked 15 cigarettes a day but drank very little. She had no pets and had not been abroad. Examination was unremarkable apart from the acne. Investigations, which included examination of fxces for ova, cysts, parasites, and occult blood, X-rays (barium meal, small-bowel meal, barium enema), sigmoidoscopy, and jejunal biopsy, were all normal except for a hiatus hernia. She did not improve when tetracycline was withdrawn or when antidiarrhoeal agents or tranquillisers were tried. Her symptoms continued for 2 years. However, when a gluten-free diet was tried the diarrhoea stopped within 4 days and the patient felt very much better. Jejunal biopsy was repeated after 6-week gluten challenge (accompanied by recurrence of diarrhoea) but was normal in every way including normal intraepithelial lymphocytecounts. Resumption of the gluten-free diet was followed by a rapid disappearance of all her symptoms. We consider it very likely that this woman’s symptoms were due to gluten sensitivity. Her recovery is unlikely to be a placebo response because other treatments had failed; moreover,

growth of symptom-free persons with pseudohypoaldosteronism has not been described. As this syndrome is probably more common than previously thought, we suggest that plasma aldosterone and renin be measured in the evaluation of short stature, especially if there is a suggestive family history. Early salt treatment in proven symptom-free patients seems logical.

INHERITANCE OF PSEUDOHYPOALDOSTERONISM

SIR,-The exact mode of inheritance in pseudohypoaldosteronism needs clarifying since few pedigrees have been reported. Dr Limal and colleagues (Jan. 7, p. 51) proposed autosomal dominance with variable expression. We have seen a female infant with pseudohypoaldosteronism family studies, confirm Limal’s suggestion. The girl was born after an uncomplicated full-term pregnancy, birth-weight 2600 g. She was admitted at 3 months of age because of failure to thrive and severe dehydration. Electrolyte determinations revealed persistent hyperkalsemia. The plasma-aldosterone at 4.5 months was 600 ng/dl. The infant was discharged at this time weighing 4120 g. The results of plasma aldosterone, renin, and urine aldosterone at the age of 6 months are shown in the table. Her mother had been in hospital several times during infancy because of vomiting and failure to thrive and had received parenteral fluid. Since the age of 1 -years she had gradually recovered, without any specific treatment. We examined five more members of the family who

drawn in the morning after the patients had got up. Aldosterone was isolated from the methylene chloride extract of plasma and urine by immunological purification before radioimmunoassay.2 The normal ranges for plasma and urine aldosterone are 2-14 ng/dl and 2-14 ;j.g/24 h, respectively. The plasma-renin-activity (P.R.A.) was determined by angiotensin I radioimmunoassay kit (New England Nuclear). The normal base values range from 0.6 to 3-0

The affected family members, except for one brother, have short stature. Moreover, the propositus was just below the 3rd percentile at the age of 6 months and remained so until we began a high-salt diet at the age of 8.5months. The treatment resulted in a catch-up growth concomitant with the expected lowering of aldosterone and renin values. Catch-up growth in salt-losing syndromes after high-salt diet is well known.2-4 However, the influence of this treatment

genital adrenal hyperplasia (C.A.H.) is closely linked to the HLA B locus. This means that it might well be possible to use specific antibodies to eliminate the 50% of the paternal sperms2,3 which carry the marker HLA B antigen and then carry out artificial insemination with the remaining spermatozoa. Using this method the chances for the offspring of heterozygote (for C.A.H. and father for HLA B) parents, should be improved to almost 50% carrier-free and 50% heterozygotes. The same could be applied to HLA B27 fathers with ankylosing spondylitis. Universitätskinderklinik München, 8 München 2, West Germany

FINE-NEEDLE PERCUTANEOUS TRANSHEPATIC CHOLANGIOGRAPHY

SiR,—Our experience confirms

your support for fine-needle percutaneous transhepatic cholangiography in the investigation of jaundice (May 27, p. 1139). In ninety-six consecutive cholangiograms done in this way there has been only one failure to outline the ducts, and there have been no serious com-

The diagnostic accuracy is excellent, as judged by definition of the level and cause of obstruction. Failure to enter the bileducts does not completely exclude obstruction as the intrahepatic ducts may be of normal fine calibre in some cases of gallstone obstruction. This diagnostic technique is safe and sure, largely due to the use of the lateral approach, slim needle, and prophylactic antibiotics. Drainage of the ducts is a therapeutic measure which requires the insertion of a much larger calibre flexible catheter. It is attended by greater risks such as bile leakage, of a degree that caused the older methods of transhepatic cholangiography
