RESUMEN
Pregnancy has long been associated with the first presentation of clinical leprosy or aggravation of the existing disease. In Germany leprosy has been diagnosed in 107 patients since 1980. A 27-year-old Singhalese female, gravida 2 at 14 weeks' gestation was admitted with well defined, elevated, erythematous lesions on her cheeks and nose. Clinical examination revealed central anaesthesia in the lesions. No further signs of leprosy in the skin, the mucosae and the peripheral nerves were found. Fite-Faraco staining of the skin biopsy showed sporadic acid-fast bacilli and confirmed an active subpolar tuberculoid leprosy (TTs). Outpatient treatment was immediately initiated with oral rifampin 600 mg monthly and dapsone 100 mg daily. During the 4-month treatment cycle the skin lesions vanished completely. Additional leprosy reactions did not occur and the medication was well tolerated. However, in the 32nd gestational week the patient was readmitted with premature labour and 3 weeks later Caesarean section was performed because of cardiotocographic pathology. Polymerase chain reaction (PCR) for M. leprae of placental tissue was negative. Antibodies against phenolic glycolipid 1 (PGL 1) of M. leprae (IgM-Elisa and Dot-Elisa) from cord blood, maternal and newborn blood were not found. On the fifth postpartal day the healthy mother and her baby were discharged. In conclusion, leprosy in pregnancy can be treated safely and successfully by combined drug therapy.

Three pregnant lepromatous armadillos along with the three sets of four fetuses and their placentae were studied histopathologically. Mycobacterium leprae were present in the decidual tissue, trophoblastic cells which line the chorionic villi, and in the cells that form the internal structure of the villi. Acid-fast organisms were also seen in the spleens of three fetuses. Congenital infection is clearly possible in leprosy in the armadillo and may also occur in humans.

Eighty-one placentae from women with leprosy and 17 placentae from healthy controls were subjected to a detailed macroscopic, light microscopic, ultrastructural, immunopathological, microbiological and biochemical study. The placental morphology and immunohistology were normal, and there was no morphological evidence of infection of the placenta due to M. leprae. No acid-fast bacilli or acid-fast bacillary granules were seen on light microscopy of any of the placentae from leprous women, although homogenates from two out of seven placentae from women with very active lepromatous leprosy contained acid-fast bacilli in very small numbers. The small placental size of women with leprosy, most marked in those with lepromatous leprosy, appears to be due to a decrease in placental cell size, rather than to a reduced number of cells in the placenta. It is postulated that the small placenta and reduced fetal birth weight observed in lepromatous leprosy are a consequence of depressed maternal immune reactivity.

Estrogen excretion was assayed in 64 women with leprosy and 15 healthy control women. The mean estrogen excretion was lower in women with leprosy than in controls and the incidence of subnormal estrogen values was higher in the leprosy patients than in the controls. There was an association between infant birth weight and frequency of subnormal estrogen excretion. These features were most marked in women with lepromatous leprosy and are further evidence of diminished fetoplacental function in women with leprosy.
