Between September 1987 and September 1990, health workers in Himachal Pradesh State in India collected serum samples from 1305 patients at sexually transmitted disease (STD) clinics, 1274 blood donors, 271 hospital staff handling blood products, and 150 foreigners to screen high-risk populations for reactivity to HIV, hepatitis B virus (HBV), and syphilis. Most of the samples were from males (2373 males vs. 626 females and 1 eunuch). None of the cases from India tested HIV positive, while 3 foreign national cases did. 2 of the foreign nationals were Canadian and the other was Kenyan. 2 foreigners tested positive for both HBV and HIV. Overall, 5.53% tested positive for HBV and 9.07% for syphilis. 9.4% of the Indian individuals tested positive for syphilis, which was higher than an earlier study in Himachal Pradesh. Most people who tested positive for HBV and syphilis were 21-30 years old. 2.14% of the STD patients tested positive for syphilis and HBV, while only 0.37% of hospital personnel. 0.67% of foreigners, and none of the blood donors did. STD patients also had the highest percentage of syphilis-positive (19.69%) and HBV-positive results (8.73%). HBV-positive incidence was about 3 times greater in people who also tested positive for syphilis. Since reactivity to syphilis was associated with poverty, poor hygiene, polyandry, polygamy, and illiteracy, citizens living in Himachal Pradesh were at great risk of acquiring HIV from a foreigner. Therefore, the microbiologists who examined these samples recommended more intensive and continuous screening of high-risk populations in Himachal Pradesh.

Participants in the study were drivers and turnboys who passed through a transport depot in Kampala, Uganda, in November 1986. Each participant answered a questionnaire aimed at determining basic demographic data, countries visited within the previous 3 years, level of prostitute contact within those countries, and whether they had had a history of urethral discharge or genital ulceration. A total of 45 drivers and 23 turnboys with a mean age of 38 and 26 years, respectively, were interviewed and blood samples were taken. Serological controls were selected from people of the same age as the study group from individuals donating blood. Serum immunoglobulin (Ig) antibodies to HIV were determined by a competitive enzyme-linked immunosorbent assay and a competitive ELISA using recombinant HIV core and envelope proteins. All serological results were verified by immunoblot assays or were prepared by electrophoretic separation of U937 cell lysates infected with a Ugandan HIV-1 isolate. Antibodies to Treponema pallidum were detected by a hemagglutination test. They were of Ugandan (66.2%) or Kenyan (33.8% ) origin. All were sexually active, and all denied homosexuality and intravenous drug use. The overall HIV-1 seropositivity rate was 35.2%, compared with the control group of 9.2% (24 out of 68 versus 12 out of 130; p 0.01). Using the antigen detection systems, 7 of the seronegative sera proved to be antigen positive. In addition, 4 out of the 24 seropositive sera (16.6%) also proved to be antigen positive. 36.7% of the population admitted more than 50 lifetime sexual partners. Of the remainder, 83.7% had had more than 10 lifetime sexual partners. The level of urethral discharge and genital ulceration revealed a significant difference (p 0.01) between seropositive and seronegative individuals. The overall level (55.8%) of T. pallidum antibodies among drivers and turnboys was significantly higher than in the control group (p 0.01). The drivers had the highest level of T. pallidum antibodies (62.2%) compared with turnboys (43.8%), reflecting the older average age and, thus, the greater sexual experience.

The HIV-1 population in an infected individual often includes a diverse mix of variants distinguished mainly by differences in the extracellular envelope glycoprotein. Some variants may be favored for cell- and tissue-specific replication. In order to develop a HIV-1 vaccine which will be effective worldwide, researchers need to evaluate the virus populations which are transmitted to individuals living in high-incidence areas. The authors examined the diversity of the proviral envelope gene in infected cells in the genital secretions and peripheral blood of six recently seroconverted Kenyan female prostitutes in the attempt to determine the nature of the HIV-1 population transmitted to women during heterosexual contact. Heterogeneous virus populations were present in cervical secretions and/or peripheral blood shortly after seroconversion for five of the six women, and tissue-specific variants were identified in several cases. Study findings suggest that virus heterogeneity in the cohort was due to the transmission of multiple HIV-1 genotypes.

The AIDS epidemic is a rapidly growing problem in Nairobi, where the seroprevalence in pregnant women increased from 4% in 1988 to over 10% in 1991. 22 HIV-1-seropositive pregnant women and 1 HIV-1-infected baby (K88) attending the Pumwani Maternity Hospital of Nairobi between 1990 and 1992 were studied as part of a cohort study of maternal risk factors in mother-to-child transmission. A 250-base pair (bp) fragment of the env gene encoding C2V3 was amplified mostly from DNA isolated from primary peripheral blood mononuclear cells and subsequently sequenced. The 23 newly determined HIV env sequences were aligned with 23 previously known sequences of HIV-1 isolates of diverse geographical origin and the sequence of the HIV-1-related chimpanzee isolate SIVcpz-gab, on the basis of primary structure. Distance calculation, tree construction, and bootstrap analysis were realized with the software package TREECON. In the tree, 8 major branches could be observed containing sequences representative of 8 different subtypes A, B, C, D, E, F, G, and H, besides the outlier group O. 19 of 23 Kenyan isolates clustered with D687, Z321, U455, and SF170, which were members of genetic subtype A. Phylogenetic analyses favored positioning of K976 as a divergent A subtype strain. For 4 strains (K29, K88, K98, and K112) the subtype A classification based on the gag gene was also observed on the basis of phylogenetic analysis of the C2V3 coding part of the env gene. The predicted amino acid sequence of the V3 region for these strains was also presented. The finding that among 23 HIV-1 isolates collected in Nairobi, 19 were classified in subtype A versus 3 in subtype D, together with a much larger variation between subtype A strains as compared to subtype D strains, suggests an earlier introduction of a subtype A strain, multiple introductions of subtype A strains, and/or faster diversification of subtype A strains as compared to subtype D strains.

This paper reports the findings of an evaluation of Western Kenyan blood transfusion practices used with a cohort of severely anemic women of child-bearing age. The potential of receiving HIV-infected blood puts these women at a definite health risk. Characteristics of severely anemic women included being older (P = 0.03, Wilcoxon rank sum test), lower likelihood of being pregnant when admitted to hospital (odds ratio [OR] = 0.53; 95% confidence interval [CI], 0.35-0.81), and greater likelihood of being HIV seropositive (OR = 2.92; 95% CI, 1.52-5.60) when compared to non-anemic women. Severely anemic women were also less likely to have malaria (OR = 0.58; 95% CI, 0.35-0.96). Women who had a transfusion ordered had a higher mortality rate than women who did not (25/240, 10.4% vs. 18/933, 1.9%)(OR = 5.91; 95% CI, 3.04-11.53). In this study, positive benefits were restricted to women who had a transfusion only for them. These were the severely anemic women. The attributed mortality caused by HIV infection and severe anemia was 75% and 31%, respectively. Detection of HIV infected blood is very critical. Prevention of anemia is considered more important than transfusing concerns. Preventing the need for transfusions would reduce the HIV transmission risk from potentially infectious blood during transfusion.

In Kenya, health professionals compared prospective data on 193 suspected malaria patients at the Eldoret District Hospital during February-March, 1992, with retrospective data on 120 suspected malaria cases at the same hospital during November-December, 1991, to examine the protocol on the management of suspected malaria cases. Between these 2 periods, physicians introduced a simple algorithm to follow in suspected malaria cases. The use of quinine as the 1st choice drug fell considerably between the 2 periods (54.2-19%). There was an increase in the use of chloroquine as the 1st choice drug for uncomplicated malaria (38.4-63.9%). The proportion of blood smear positive patients increased (27.5-51.3%), probably because the department technician was more careful conducting repeat blood smears than were technicians at the busy hospital laboratory. Blood smear negative patients were less likely to automatically receive any antimalarial treatment or quinine in 1992 than in 1991 (14.6% vs. 47.5% and 4.1% vs. 30.9%, respectively). The proportion of patients whose final diagnosis was an illness other than malaria was higher in 1992 than in 1991 (19.7% vs. 15.8%). No clear diagnosis other than flu-like illness was the case for 28 (14.5%) of the prospective patients. The tendency for clinicians to accept a diagnosis of malaria without enough evidence to confirm it can have the damaging effect of masking other serious diagnoses (e.g., dysentery [8 cases], meningitis [6 cases], and HIV infection [2 case]). These findings show that hospital physicians should develop simple protocols for inpatient management of suspected malaria cases, a properly quantified blood smear should be done of all suspected malaria cases to confirm or refute the diagnosis, and chloroquine should be the 1st line of treatment in the Kenyan highlands, until considerable parasite resistance is confirmed.

To evaluate the knowledge, attitudes and sexual behaviour with respect to HIV and AIDS among Kenyan secondary school students, a questionnaire was issued to 3,018 students of mean age 16.3 years in 11 Kenyan schools. Questions of knowledge were answered correctly by an average of 77.1% of students. Areas where students' knowledge was less complete included the inability of mosquitoes to transmit the virus, the protective effect of condoms, the lack of protection from medications, the fatal and incurable nature of AIDS, and the fact that those infected with HIV may appear healthy. No prior sexual experience was reported by 71.3% of females and 25.2% of males. Multiple sexual partners were reported by 41.2% of males and 7.3% of females. Sixty per cent of students denied ever using condoms during sex and only 6.8% of those with multiple partners used them all the time. A prior sexually-transmitted disease was reported by 5.6% of students. Although a high level of knowledge regarding HIV and AIDS is evident among Kenyan students there is a sizable number who admit to extensive sexual experience, but who are not using condoms, thereby putting themselves at risk.

Over a period of 6 to 24 months a long term follow up of the in vitro antifungal susceptibility of 306 Candida albicans strains from 49 HIV-infected patients was performed. Using a microdilution test, the strains were tested against the azoles ketoconazole, itraconazole and fluconazole. The susceptibility range for fluconazole was between 1 and 128 mg/l, for itraconazole between 0.015 and 32 mg/l and for ketoconazole between 0.007 and 16 mg/l. 11.7% of the strains showed elevated IC30-values against ketoconazole, 9.1% against itraconazole and 10.1% against fluconazole. Sterol biosynthesis was examined by thin layer chromatography in 18 less sensitive strains and nine sensitive strains in the presence of ketoconazole. The proportion of ergosterol in the presence of ketoconazole at a concentration of 0.003 mg/l varied between 7.6% and 21.1% in sensitive strains and between 11.1% and 86.6% in less sensitive strains. In resistant control strains the proportion of ergosterol was 73% and 94.2%, respectively. Without ketoconazole the ergosterol proportion was > 85% in all strains. There was a significant correlation between the IC30-values and the inhibition of ergosterol biosynthesis (p = 0.05).

In East Africa, Streptococcus pneumoniae is a common and serious, but potentially preventable, human immunodeficiency virus type 1 (HIV-1)-associated pathogen. For 54 HIV-1-infected women, baseline levels of capsule-specific antibody to 2 of 4 pneumococcal serotypes were lower than levels in 15 seronegative women (P < .05). After immunization, specific antibody to all 4 serotypes increased in HIV-1-infected and -uninfected women (P < .05). Convalescent levels for 2 of 4 serotypes were greater in seronegative women, but the levels were not different between HIV-1-infected women with (n = 21) or without (n = 33) prior invasive pneumococcal disease. The baseline functional activity to kill S. pneumoniae type 14 was lower in HIV-1-infected than -uninfected women but also rose significantly in all groups after immunization. It is concluded that HIV-1 infection in Kenyan women is associated with decreased levels of natural antibody to selected pneumococcal capsular serotypes, but the vaccine is immunogenic in these patients who are at high risk of invasive pneumococcal disease.

President Daniel arap Moi and the ruling party of Kenya, KANU (Kenyan African National Union), have bowed to election year pressure from anti-abortion groups and Catholic bishops, including Bishop Alfred Rotich who led a anti-sex education demonstration in Nairobi, and shelved a sessional paper on family life education that was to be discussed by parliament this month. If the paper had been adopted, sex education could have been introduced in the schools and integrated with primary health care. The document would have been the basis for making students aware of the dangers of adolescent pregnancy, abortion, drug abuse, HIV/AIDS, and sexually transmitted diseases (STDs). 12% of the girls who leave school are pregnant or have married early; 10,000 girls become pregnant per year according to Ministry of Education estimates. The local AIDS council believes that the pandemic is on the rise among Kenyan youth; it is estimated that 1-3 million persons will become infected by the year 2000 and that Kenya will have more than a million AIDS orphans. Real intervention would be to create awareness and provide family planning services, according to the council. Bishop John Njue, Chairman of the Kenya Episcopal Conference, states that the Catholic Church will fight any introduction of sex education in the schools.
