Megaloblastic Anaemia Due to Phenytoin Sodium

Megaloblastic anaemia due to sulphasalazine responding to drug withdrawal alone.

A 60 year old man with ulcerative colitis since 1975 and treated with sulphasalazine, presented with severe megaloblastic anaemia caused by folate deficiency. The drug was stopped, and the anaemia recovered promptly. There was no relapse one year later.

Megaloblastic anaemia due to trimethoprim-sulphamethoxazole therapy in uraemia.

Aminoaciduria and megaloblastic anaemia.

Urinary amino-acid chromatograms from 23 patients with megaloblastic anaemia have been studied before and after therapy. The most consistent abnormality was an increased taurine or increased taurine/glycine ratio. This was not related directly to deficiency of vitamin B(12) or folic acid or to the degree of anaemia.

Megaloblastic Anaemia in Haemochromatosis.

IN 1877 Muller described a marked bronzed discoloration of the skin in some patients considered to have pernicious anaemia. This observation, confirmed later by Immerman (1879) is likely to be the first record of an association between a macrocytic type of anemia and haemochromatosis. Since that time French (1909), Roth (1915), Bork (1928), Cain (1940), Hotz (1944) and Harvier and Mallarme (193...

Potassium changes in megaloblastic anaemia.

1. Serial measurements of serum potasssium and total-body potassium were made on eighteen patients with megaloblastic anaemia before the start of therapy and during the period of recovery. 2. In those patients who presented with an initial packed cell volume of less than 25%, a mean decrease in serum potassium of 0.4 mmol/1 occurred on average with 2.5 days of the start of therapy. This was f...
