Epidemiologic Notes and Reports Adult T-Cell Leukemia/Lymphoma Associated With Human T-Lymphotropic Virus Type I (HTLV-I) Infection -- North CarolinaA case of adult T-cell leukemia/lymphoma (ATL) associated with human T-lymphotropic virus type I (HTLV-I) has been reported from North Carolina. The patient, a black adult male, developed jaundice in December 1986, after several weeks of anorexia, fatigue, and fever. When admitted to the hospital, he had an enlarged liver, a serum bilirubin level of 15.5 mg/dL, and an SGOT level of 279 IU/L, but serologic tests for hepatitis B markers and hepatitis A antibody were negative. Ultrasound examination revealed no evidence of intra- or extra-hepatic obstruction. He was thought to have alcoholic hepatitis. During the next week, he became pancytopenic, and bone marrow biopsy revealed hypocellularity of all cell lines but no malignant infiltrates. He was given transfusions of red blood cells and platelets and was discharged in February 1987, despite continued clinical and laboratory abnormalities. The diagnosis upon discharge was resolving hepatitis. In March 1987, the patient returned to the hospital because of abdominal pain, nausea, vomiting, and somnolence. Laboratory studies revealed a leukocytosis with abnormal lymphocytes, a calcium level of 20.5 mg/dL, and an amylase level of 1,209 IU/L. He was thought to have ATL with hypercalcemia and consequent acute pancreatitis. His condition deteriorated despite chemotherapy and treatment for hypercalcemia, and he died on March 22. Autopsy revealed leukemic infiltrates in the spleen, bone marrow, and kidneys. When peripheral blood mononuclear cells obtained before the patient's death were subjected to flow cytometric analysis, 95% of the cells were of the CD4+ (T-helper cell) phenotype. Antibodies against HTLV-I were detected in several serum samples by radioimmunoassay and by Western blot. HTLV-I was isolated from the man's peripheral blood lymphocytes. The patient had served in the U.S. Army in South Vietnam, Korea, and Germany and had gone to North Carolina after discharge. He was divorced at the time of his illness. He had used intravenous drugs and had shared needles with a woman with whom he had had sexual contact for 2 years before his illness. He had never had a blood transfusion. Serum specimens were obtained from 28 family members and sexual contacts of the patient. Five of these persons had antibodies against HTLV-I. They comprised the woman with whom the patient had had sexual contact and had shared needles, this woman's former husband, another former female sexual partner of the patient, the patient's sister, and the sister's daughter. None of these persons had lived outside the United States or had received blood transfusions, and none other than the woman with whom the index patient had shared needles were known to have used intravenous drugs. A serosurvey of 245 attendees at sexually transmitted disease and family planning clinics in the county in which the patient had resided revealed no persons seropositive for antibody against HTLV-I.

Editorial NoteEditorial Note: HTLV-I, the first human retrovirus to be discovered, was first isolated and reported in the United States in 1980 (1) and in Japan in 1981 (2). Infection with HTLV-I, like infection with other retroviruses, probably occurs for life and can be inferred when antibody against HTLV-I is detected in the serum. Studies of HTLV-I antibody indicate that the virus is endemic in southern Japan (3), in the Caribbean (4), and in Africa (5,6). HTLV-I infection in the United States appears to be rare. Although little serologic data exist, prevalence of infection is thought to be highest among blacks living in the Southeast (7). A prevalence rate of 30% has been found among black intravenous drug abusers in New Jersey, and a rate of 49% has been found in a similar group in New Orleans (8). It is possible that prevalence of infection is increasing in this risk group. ATL is usually a highly aggressive non-Hodgkin's lymphoma with no characteristic histologic appearance except for a diffuse pattern and a mature T-cell phenotype. Circulating lymphocytes with an irregular nuclear contour (leukemic cells) are frequently seen. Several lines of evidence suggest that HTLV-I causes ATL. This evidence includes the frequent isolation of HTLV-I from patients with this disease and the detection of HTLV-I proviral genome in ATL leukemic cells (9). ATL is frequently accompanied by visceral involvement, hypercalcemia, lytic bone lesions, and skin lesions (10). Most patients die within 1 year of diagnosis. ATL is relatively uncommon among those infected with HTLV-I. The overall incidence of ATL is estimated at about 1 per 1,500 adult HTLV-I carriers per year (11,12). Those cases that have been reported have occurred mostly among persons from the Caribbean or blacks from the Southeast (National Institutes of Health, unpublished data). The presence in this investigation of family members and sexual contacts who are seropositive for HTLV-I is consistent with current knowledge concerning transmission of HTLV-I infection. Transmission occurs from mother to child; by sexual contact; and through exposure to contaminated blood, either through blood transfusion or sharing of contaminated needles. The source of the patient's sister's infection is obscure. She and her brother may have acquired infection from their mother, who is deceased. Because of the rarity of ATL in the United States and the potential for learning more about the transmission of HTLV-I in the United States, physicians who see adults with diffuse non-Hodgkin's lymphoma with at least two features consistent with ATL (abnormal lymphocytes on peripheral blood smear, T-cell phenotype of malignant cells, visceral involvement, hypercalcemia, lytic bone lesions, and skin lesions) are encouraged to report these cases through their local and state health departments to the Retrovirus Diseases Branch, Division of Viral Diseases, Center for Infectious Diseases, CDC, telephone number (404) 639-3091.
