[Evidence of infection by HIV-2 in Madrid (1991)].

The presence of antibodies against HIV-2 was analyzed in serum samples from high-risk individuals for retrovirus infection, who were seropositives for HIV-1. Out of a total of 842 samples, 344 presented positive absorbency and 16, threshold ranges, in an enzymatic immunoassay (EIA) designed to detect simultaneously antibodies against HIV-1 and HIV-2. The Western Blot (WB) analysis confirmed the presence of antibodies against HIV-1 in 324 samples with positive or threshold EIA, while it was indetermined in 15 samples. WB was negative in 11 samples. In the 15 samples with indetermined WB and in the 16 samples with threshold EIA, the presence of antibodies against HIV-2 was investigated with an specific WB and a test designed with synthetic peptides (Pepti-lav). Three samples met the isolated seropositivity criteria for HIV-2. Those samples were from 3 african immigrants living in Madrid, which, until now, were asymptomatic, although one of them presented biological signs of immunodeficiency. None of them referred high-risk infectious practices, such a homosexuality or drug-addiction, although all of them referred heterosexual contacts in their native countries. Samples from native subjects meeting serum positivity criteria for HIV-2 were not identified.

[Visceral leishmaniasis: a study of 15 cases].

We report 15 cases of visceral leishmaniasis in adults, diagnosed by visualization of the parasite in 14 of them and in one case, based on clinic, serology and good response to treatment. Thirteen patients developed an acute clinical state and two patients, a subacute-chronic state. All of them had fever, half of them, a constitutional syndrome and 12, visceromegaly. Fifteen had anemia, 13, leukopenia and 10, thrombopenia. Serology was positive in 75% of cases. All patients were treated with meglumine antimoniate. No adverse effects were observed and in 14 patients, the treatment was successful. There were no recurrences. A patient died due to septic shock by Pneumococcus with DCI.

AIDS and tuberculosis in Spain. A report of 140 cases.

From January 1984 to October 1990, 140 of 392 (35.7%) patients with the acquired immunodeficiency syndrome (AIDS) were found to have had tuberculosis. One hundred and sixteen were intravenous drug abusers and 16 were homosexual men. Fever, cough, weight loss and generalised lymphadenopathy were common features of their illness. Tuberculin skin tests were negative in 74% and 55% had intraabdominal lymphadenopathy. The chest radiographs showed hilar lymphadenopathy and lower lobe interstitial or alveolar infiltrates, but rarely cavitation. Forty-one of our patients had pulmonary tuberculosis, 38 had extra pulmonary and in 61 it was disseminated. In 80 cases tuberculosis was the presenting feature of AIDS. Tuberculosis usually responded well to chemotherapy.

In vitro chloroquine-resistant falciparum malaria in Malabo, Equatorial Guinea: case reports.

For many years the chloroquine-resistant problem in Africa was circumscribed to East Africa, but in the last two years it has been spreading progressively to the West. We report here the two first cases of chloroquine-resistant falciparum malaria imported into Spain from Equatorial Guinea. Both cases show a parasitological grade III resistance in a W.H.O. in vitro macrotest. The clinical recovery with the alternative treatment (Fansidar) was satisfactory.

Imported schistosomiasis in Europe: sentinel surveillance data from TropNetEurop.

BACKGROUND: Schistosomiasis is a major parasitic disease, increasingly imported into temperate climates by immigrants from and travelers to endemic areas. METHOD: To generate valid data on imported infectious diseases to Europe and to recognize trends over time, the European Network on Imported Infectious Diseases Surveillance (TropNetEurop) was founded in 1999. Three hundred and thirty-three reports of schistosomiasis were analyzed for epidemiologic and clinical features. RESULTS: Male patients accounted for 64% of all cases. The average age of all patients was 29.5 years. The majority of patients were of European origin (53%). Europeans traveled predominantly for tourism (52%). Main reasons for travel for people from endemic areas were immigration and refuge (51%) and visits to relatives and friends (28%). The majority of infections were acquired in Africa; 92 infections were clearly attributable to Schistosoma haematobium, 130 to Schistosoma mansoni, and 4 to Schistosoma intercalatum. Praziquantel was the only treatment used. No deaths were recorded. CONCLUSION: TropNetEurop sentinel provides valuable epidemiologic and clinical data on imported schistosomiasis to Europe.
