[Autoimmune thrombopenic purpura and pregnancy. Absence of thrombopenia in the newborn infant despite the presence of circulating IgG auto-antibody in the mother].

Many pregnant women with AITP bear children with transient thrombocytopenia which is a potentially life threatening complication. Previous reports have demonstrated that monitoring of IgG circulating platelet antibodies may help with the management of these women. We report the case of a pregnant woman with AITP whose sera contained an IgG auto antiplatelet demonstrated by the fluorescein labelled antiglobulin techniques. Steroids had a beneficial effect with a return to a normal of the mother's platelet count but with no disappearance of the circulating antibody. Surprisingly the neonatal platelet count was normal and studies in the baby showed that the antibody had not crossed the placenta in detectable amounts. This case demonstrates our current inability to predict fetal thrombocytopenia and plan the mode of delivery.

Early response to chemotherapy as a prognostic factor in Hodgkin's disease.

In 164 patients with Hodgkin's disease staged between 1973 and 1979 the response to the 3 initial cycles of multiagent chemotherapy was evaluated as a prognosticator of survival. Treatment of localized disease (Stages I, II, III1) consisted of 3 cycles of chemotherapy followed by subtotal nodal irradiation, including the splenic area in non splenectomized patients. Treatment of extended disease (Stage III2 and IV) consisted of 6 cycles followed by low-dosage radiotherapy of initial bulky disease. Five-year actuarial survival was 88% in Stage I, 80% in II, 100% in III1, 45% in III2 and IV. Chemotherapy-induced complete remission after 3 cycles (CH leads to CR) was associated with a favorable prognosis. Five-year survival of Stage III2 and IV patients was better in those who reached CH leads to CR than in those who did not (75% versus 25%; P less than 0.01). This relationship between CH leads to CR and five-year survival was confirmed in patients with localized disease, as shown in Stage II patients (respectively 97% versus 63%; P less than 0.05). Therefore the response to initial chemotherapy provides a new prognostic factor that may serve to delineate a "high-risk" group of patients. The latter deserve aggressive therapy while those in the favorable group would benefit from a less aggressive combined regimen that would minimize long-term complications.

[Multiple myeloma with high tumoral mass. Treatment combining melphalan, cyclophosphamide, vincristine, CCNU and prednisone. 35 cases].

The results of a combination chemotherapy trial (melphalan, CCNU, vincristine, cyclophosphamide) involving 28 patients with stage III (n = 21) or stage II (n = 7) multiple myeloma suggest a high response rate, with a mean 71% malignant cell destruction in 78.5% of the patients. A longer survival in responsive stage III patients as compared with patients treated with alkylating agents seems likely, but this can only be established by a randomized trial. Despite haematological side-effects, this combination therapy may be used in high risk patients, especially those resistant to a single alkylating agent and in whom the frequency, intensity and duration of responses appears to be the same as in previously untreated patients. In contrast, only one of the 7 patients treated for relapse after previous response to a single alkylating agent responded to the combination chemotherapy.

Adult T-cell lymphoma leukemia in Western countries.

A new T-cell disorder has recently emerged: the so-called adult T-cell lymphoma leukemia (ATLL) initially described in Japan. Subsequently, ATLL cases were recognized in patients from the Caribbean. We summarize the clinical and hematological features of 19 published cases from Western countries, in addition to a new case we encountered. The leukemic cells display characteristic morphological features and a T3+T4+T8-T6- surface antigenic phenotype. Overall survival is of short duration, but remission could be obtained in our case despite a subsequent relapse in skin and CNS. Geographic clusters of ATLL cases have led to the discovery of the possible role of a new retrovirus, HTLV, in the genesis of this rare malignancy.

Liver complications in lymphomas treated with a combination of chemotherapy and radiotherapy: preliminary results.

From May 1978 to May 1981, a total of 20 patients (18 patients with Non Hodgkin Lymphomas + 2 patients with Stage IV Hodgkin's disease) were treated with chemotherapy and whole or upper abdominal radiotherapy. All the patients were in complete remission at the time of irradiation. Shielding of the kidneys was effected at the start of treatment and the right lobe of the liver was shielded after a dose of 20 Gy was delivered. As of January 1982, 17 of the patients were alive and free of disease with a follow-up ranging from 6 to 32 months (mean follow-up of 18.5 months). Two patients were dead from their disease. Alterations in liver chemistry were observed in 5 patients, clinical jaundice or transient hepatomegaly along with changes in liver chemistry in 4 patients, classical veno-occlusive disease in 2 patients and 7 of the patients did not develop any complication. No death from complications were observed. The contribution of the following factors such as radiotherapy dose to the liver, drugs, nutritional status and associated medical conditions, towards the development of complications have been analyzed in detail.

[Hematologic anomalies in Lyell's syndrome. Study of 26 cases].

Case records of 26 patients with Lyell Syndrome were reviewed for studying haematologic abnormalities. Eosinophilia, neutropenia, thrombopenia were uncommon. Circulating immature granulocytic cells were frequently encountered during the second week of evolution, mostly when leucocytosis was present. Anemia was frequent, the lowest haemoglobin titer beeing reached by the 15th day. Reticulocytosis was initially low and reached a peak during the second week. At that time biological markers of inflammatory syndrome were getting worse. So the originating anemia seems primarily of medullary origin and independent of inflammatory syndrome. Lymphopenia was constant and sometimes marked, with no circulating lymphocytes in two cases. The lowest numbers of lymphocytes were observed during the first week. These haematological abnormalities may have some pathogenic significance.

A hypereosinophilic syndrome with retinal arteritis and tuberculosis.

A 35-year-old man was initially seen with a decrease in visual acuity, renal insufficiency, and elevation of the eosinophil count in the blood. The ocular syndrome was caused by extensive arterial occlusions of the retina. The subsequent apparition of cardiac, pulmonary, and neurologic signs fulfilled the criteria for the diagnosis of hypereosinophilic syndrome (HES). Most symptoms, including ocular, were temporarily but notably improved by hydroxyurea. The patient died after two years. An autopsy showed an endomyocardial fibrosis and disclosed destruction of the left kidney by an active tuberculosis. A pathogenic relationship between the infectious disease and the HES is envisaged.

Acute non myeloid leukaemia in adults. Prognostic factors in 92 patients.

An analysis of prognostic factors was performed on a series of 92 adult patients with acute non-myeloid leukaemia (ANML). Four factors were shown to be correlated with a poor short-term prognosis: (1) Neuropathy involving a single cranial nerve (numbness of the chin) as a presenting feature. (2) A low percentage blast cell infiltration of bone marrow (less than 55%). (3) Cytological L2 type or L3 type of cells according to FAB classification proposals. (4) Increased age. Two factors were shown to be correlated with a poor long-term prognosis: 1) A high level of circulating blast cells; 2) A high tumour burden, as in childhood ANML. These two long-term prognostic factors were interrelated. In addition, our results suggested that myelofibrosis could be a poor long-term prognosis factor as well.

[Comments about use of polychemotherapy MOPP associated with radiotherapy in the treatment of early stages of Hodgkin's disease. Preliminary report of 58 patients (author's transl)].

58 patients with early stages of Hodgkin's disease (I, II, III l) were treated by 3 courses of MOPP chemotherapy followed by extended field irradiation. After 31 to 72 months follow up 87,8 p. 100 of patients are alive in complete remission. The study of the group deserves two comments: 1. Adjuvant MOPP polychemotherapy may be useful, only when a complete response is obtained after 3 courses, when it is so a complete remission of long duration may be hoped in nearly 100 p. 100 of cases. 2 After complete remission induced by combined chemotherapy and radiotherapy, maintenance chemotherapy seems to be useless.
