cin. Perhaps the Black skin is more sensitive to the pigmentary action of the drug. The effect did not seem to be dependent upon ultraviolet light since skin which was not exposed to the sun was also involved. Serum from the first two patients was assayed for &bgr;-M.S.H.7 and K-M.s.H." activity by radioimmunoassay. M.S.H.-induced hyperpigmentation is associated with values greater than 100 ng/1, but concentrations of &bgr;-M.S.H. (47 and 10 ng/l, respectively) and a-M.S.H. (36 and 64 ng/1, respectively) were normal in both patients, as were plasma-cortisol and serum-electro-

lytes.

SIR,-Longitudinal pigmented banding of the nails has been reported in patients receiving doxorubicin (’Adriamycin’).’ Cyclophosphamide and other chemotherapeutic agents produce a similar effect. 1-4 The pigment is presumed to be melanin, although the pathogenesis of the increased pigmentation has not been established. Melanin pigmentation of the nails occurs in hypoadrenalism,56 and it has been suggested that adriamycin may suppress hormone production by the adrenal gland, thereby causing excessive release of melanocytesumulating hormone (M.s.H.) by the pituitary gland.’ Assay of serum-M.s.H. activity in patients with adriamycin-induced hyperpigmentation may help to elucidate the cause of the pigmentary disturbance. We have cared for three Black women with histologically proven hepatocellular cancer all of whom developed hyperpigmentation of the skin and nails while

findings make it unlikely that increased secretion of by the pituitary is the cause of the pigmentary change and argue against the drug exerting a suppressive effect on adrenocortical hormone production. Normal M.S.H. levels also exclude the possibility that either hypoadrenalism secondary to adrenal destruction by metastases or ectopic production of M.S.H. by the liver cancer was responsible. Although it is conceivable that the tumours may have been secreting peptide fragments with M.S.H. activity which did not cross-react with either of the assays, the appearance of the hyperpigmentation after only the second injection of adriamycin and the fact that the pigment began to fade after stopping the drug do not support this possibility. Although the cause of adriamycin-induced hyperpigmentation has not been established, it seems to be independent of both M.S.H. activity and ultraviolet light. A direct effect of the drug on melanocytes seems likely. M.S.H.

SPECIFIC CELL-MEDIATED IMMUNE DEFECT IN CONGENITAL CYTOMEGALOVIRUS INFECTION

SIR,-Infants with congenital cytomegalovirus (c.ns.v.) infection manifest clinical and virological evidence of infection for many months or years despite their ability to develop humoral antibodies to C.M. v.1This suggests an underlying cellmediated defect in the host’s immune response to the virus. We have studied the in-vitro lymphocyte proliferative response to concentrated, purified c.M.v. antigen in two patients with con-

in two of them serum levels of p and ex determined. The increased pigmentation, which was shown histologically to be due to melanin, appeared after the second injection of adriamycin (60 mg/m2 body-surface area intravenously) and increased until after the fourth (and final) injection. Thereafter it began to fade. The first patient died 2 months after the fourth injection and the second 3 weeks after the fourth injection. The third patient is alive 5 weeks after the last injection. One patient had increased pigmentation of the hands, feet, and face besides the nails while in the other two the nails and palms were pigmented (see figure), indicating a more widespread effect than has previously been reported with adriamy-

receiving adriamycin; M.s.H. were

genital c.M.V. c.M.v. (strain AD169) was grown in human diploid fibroblast (foreskin) cells, harvested from the extracellular fluid, and concentrated and purified by sucrose gradient and caesium-chloride gradient ultracentrifugation. The infectivity of the final preparation was approximately 10’’1 median tissueculture-infecting doses/0.1 ml. Mononuclear leucocytes from healthy control adult donors and patients with congenital c.M.v. were isolated by ’Ficoll-Hypaque’ density centrifugation and incubated with c.M.v. for 7 days at a cell concentration of 105 mononuclear cells per well in plastic microtitre plates. Cultures were done in triplicate. Response was determined by incorporation of tritiated thymidine into new D.N.A. in dividing lymphocytes. Peak responses for control lymphocytes were obtained at dilutions of 1/5

This may reflect immune tolerance resulting from antigenic challenge early in gestation when self-recognition may not yet be established. We have started treating these patients with dialysable transfer factor prepared from c.M.v.-responsive lymphocytes in an attempt to reverse this antigen-specific cell-mediated immune defect. were
