Anaplasmosis in Uganda. II. Prevalence of bovine anaplasmosis in Uganda.

The prevalence of bovine anaplasmosis was studied in 320 Zebu cattle randomly selected from three regions of Uganda: (Central, Southwestern and Northwestern) using dot-ELISA, Western immunoblotting, rapid card agglutination test (RCAT), capillary tube agglutination test (CAT), complement fixation test (CFT), and parasitological techniques. Dried blood on Whatman filter paper No. 1 was eluted in PBS 0.05% Tween 20 prior to testing at an initial dilution of 1:25. The prevalences of parasitaemia were 25% in the central region, 28% in the southwestern region, and 35% in the northwestern region, and the serological prevalence was lowest in the central region and highest in the northwest. Overall, prevalence rates obtained by dot-ELISA (61.9%) and Western immunoblotting (62.5%) were 1.5 times those obtained by RCAT (41%) and three times those obtained by CAT (22.5%). The overall prevalence rates obtained by dot-ELISA and Western immunoblotting compared favourably with the CFT data. The present data utilizing dried blood on filter papers indicate that there is a high prevalence of anaplasmosis in those regions of Uganda surveyed, and confirm our observations and those of others that collecting blood on filter papers is a suitable technique for large scale screening and for seroepidemiological studies.

Sleeping sickness in Uganda: a thin line between two fatal diseases.

OBJECTIVE: To determine, through the use of molecular diagnostic tools, whether the two species of parasite that cause human African trypanosomiasis have become sympatric. DESIGN: Blood sampling of all available patients between June 2001 and June 2005 in central Uganda and between July and September 2003 in northwest Uganda and analysis of subcounty sleeping sickness records in Uganda between 1985 and 2005. SETTING: Sleeping sickness treatment centres in central and northwest Uganda and in south Sudan. PARTICIPANTS: Patients presenting at the treatment centres and diagnosed as having sleeping sickness. MAIN OUTCOME MEASURE: Classification of parasites from patients from each disease focus as either Trypanosoma brucei rhodesiense (acute form) or T b gambiense (chronic form). RESULTS: Blood from 231 patients with sleeping sickness in central Uganda and from 91 patients with sleeping sickness in northwest Uganda and south Sudan were screened for T b rhodesiense (detection of SRA gene) and T b gambiense (detection of TgsGP gene). All samples from central Uganda were classified as T b rhodesiense, and all samples from northwest Uganda and south Sudan were identified as T b gambiense. CONCLUSIONS: The two focuses of human African trypanosomiasis remain discrete, but the area of Uganda affected by the acute form of human sleeping sickness has increased 2.5-fold since 1985, spreading to three new districts within the past five years through movement of infected livestock. Without preventive action targeted at the livestock reservoir of this zoonotic disease, it is likely that the two disease focuses will converge. This will have a major impact on diagnosis and treatment of this neglected disease. Real time monitoring is recommended, using molecular diagnostic tools (at a regional surveillance centre, for example) targeted at both livestock and human patients.

Infant feeding practices in western Tanzania and Uganda: implications for infant feeding recommendations for HIV-infected mothers.

Current infant feeding guidelines of UNICEF/UNAIDS/WHO for HIV-infected women recommend the avoidance of breastfeeding or to breastfeed exclusively. In the context of a prevention of HIV mother-to-child transmission programme we assessed the feeding practices in peripheral areas of Tanzania and Uganda. A total of 237 mothers in south-western Tanzania and 424 mothers in western Uganda attending urban and rural antenatal care services as well as village women were interviewed with regard to duration of breastfeeding, time of introduction of additional nutrients and type of solid and liquid nutrients. The average reported duration of breastfeeding was 24 months in Tanzania but 18 months in Uganda (P < 0.001). Solid nutrients were added on average at month 6 in both areas while liquids were given significantly earlier in Tanzania (month 4) than in Uganda (month 5; P < 0.001). A total of 19% and 48% of the study participants, respectively, stated to breastfeed their infants exclusively at the age of 4 months in Tanzania and Uganda. Age between 26 and 35 years, urban residence and ethnic group were the risk factors for earlier introduction of nutrients in Uganda. In Tanzania, solid maize porridge was the most frequent (94%) and often single nutrient given during breastfeeding, while in Uganda combinations of nutrients such as bananas, millet and beans were used. Milk was the most frequently added fluid in Uganda whereas in Tanzania various liquids such as liquid maize porridge, milk, juice or water were used. Feeding practices differed considerably in the two countries. According to the interviewees, exclusive breastfeeding was rarely practiced in Tanzania. Our findings underline the necessity to promote exclusive breastfeeding if infant feeding recommendations are to be realized and emphasize the need to assess the local situation in order to ensure that locally appropriate information and recommendations are given to the target groups.

Women for women's health: Uganda.

The primary health care model targets social, political, and economic environments as key determinants of health for populations, as well as for individuals. If nursing in Uganda is to make a difference in health care outcomes and in the health of all Ugandans, nurses must look broadly at situations and be educated to practice primary health care nursing. After 14 years of civil war, Uganda is finally experiencing a period of reconstruction and rehabilitation: the whole infrastructure is undergoing a face-lift. Ugandan nurses recognize that their educational preparation has stagnated for many years and that it was not only the political unrest in their country that put them behind professionally. They realize that, given the new directions set by the government, they must become prepared to implement primary health care. They are demanding a university education so they may take their place alongside other health care providers prepared at the university level. Some of the most convincing arguments for a university program for nurses came from doctors at the university who spoke about the need to raise the standards of nursing practice, the quality of teachers, and the morale of practitioners. One nurse said: "If we lose hope for a BScN program, I think all the nurses will quit and we won't have any new students going into the profession." This program is designed to improve the health and well-being of all Ugandans, especially the most vulnerable groups of women and children in rural areas, through strengthening and expanding health services by targeting the educational preparation of nurses. Health planners in Uganda envision the professional nurse as key to the implementation of the national health policy of primary health care. University-educated nurses should be able to assess problems, make clinically sound decisions, and act appropriately within the scope of nursing practice. They should be able to interact and consult collegially with other health care professionals. Placed in rural community sites, nurses should function independently as community leaders, health education facilitators, primary health care practitioners, and educators for nursing students. Such intervention in community health care by BScN nurses should improve health care utilization and decrease mortality and morbidity from preventable causes. BScN nurses should make an impact on health care policy, nursing education, and primary health care. The evaluation of this project needs to be as comprehensive as its development and implementation. It will focus on health outcomes, particularly for women and children in rural areas of Uganda. Measurement of the effects of the process of nursing education (the BScN curriculum) in terms of output (nurses educated and placed in rural practice, nursing education, or government policy posts), outcomes (change in health status of rural communities), and broader impacts (changes in the status of women and in government policy toward women, nurses, or health at the local, regional, and national levels) is planned. An element of sustainability is present, as an operations research structure will be left in place at the community level. Timing, as the saying goes, is everything, and this project has had good timing. Our belief in the efforts and the goals of the project also gave us the strength to get support from various funding agencies for "small" things. For example, we got support from churches in the United States for building schools in Uganda; we persisted with the women's income-generating project when other support was pulled; we got books for the library in Uganda and got clothes, books, and furnishings for the students who came to this country. The motivation for project personnel has been altruism. The services that the two consultants provided to their Ugandan colleagues have extended far beyond the scope of the project.

Influences of mother's work, childhood place of residence, and exposure to media on breast-feeding patterns: experience of Nigeria and Uganda.

This study uses data from the Nigerian Demographic and Health Survey collected in 1990 and the Ugandan Demographic and Health Survey collected in 1995 to examine the implications of mother's work, childhood place of residence, and exposure to the media for breast-feeding patterns (exclusivity and intensity) in Nigeria and Uganda. Nigeria and Uganda present an interesting contrast because Nigeria is more modernized and economically developed than Uganda, thus providing a good indication of the influence of modernization on breast-feeding patterns. Mother's work status is defined by considering whether mothers earned cash from work and took their children to work, hence emphasizing the compatibility of work with child care. Work least compatible with child care had a negative effect on breast-feeding intensity in Nigeria. The negative effect of mother's work on exclusive breast-feeding (that is, if the mothers used formula or milk instead) observed for some working mothers in Nigeria and Uganda was partly confounded by urban residence, exposure to media, and other socioeconomic factors. Mother's work did not have a negative effect on breast-feeding intensity in Uganda. The relationship between mother's work, urban residence, media exposure, and breast-feeding practice seems to be stronger in Nigeria than Uganda.

The prevalence of depression in two districts of Uganda.

BACKGROUND: Little information is available on the prevalence of depression in Uganda. Given the recent political history of Uganda, depression may be common. METHOD: The aim was to estimate the point prevalence of probable clinical depressive disorder among the general population in two contrasting districts of Uganda. Translated versions (in Madi and Lusoga) of the 13-item Beck Depression Inventory (BDI) were administered to a systematic sample of adult residents in the Adjumani and Bugiri districts of Uganda. RESULTS: The overall prevalence of probably clinically significant depression (BDI score of 20-39) was 17.4%. Significantly higher rates were found in women and in Adjumani District. CONCLUSION: Depression is common in Uganda and particularly in the more troubled and less socially cohesive district of Adjumani.

Occurrence of Shiga toxin-producing Escherichia coli in fecal samples from children with diarrhea and from healthy zebu cattle in Uganda.

Fecal samples collected from 237 diarrheic infants in Kampala, Uganda and from 159 healthy cattle from a ranch in the Central Region of Uganda were investigated for the presence of Escherichia coli O157 and other types of Shiga toxin-producing E. coli (STEC). E. coli O157 were not detected in 150 stool samples from children which were cultivated on sorbitol MacConkey agar. A search for all types of STEC performed on 87 additional human stool samples with an enzyme-immunoassay for Shiga toxins (Premier EHEC) was also negative. Forty-two stool samples from infants were additionally investigated for enteropathogenic E. coli (EPEC) by DNA-hybridization with an eae-specific gene probe. Compared to STEC, EPEC were frequent and found in six (14.3%) of these 42 randomly selected stool specimens. We were further interested in the role of cattle as a reservoir for STEC in Uganda. STEC were isolated from 45 of 159 cattle from a herd in the Central Region of Uganda. STEC strains from cattle belonged to 16 different O- and nine different H-types and nine O:H types were identical to those found in bovine STEC from other continents. Only one bovine STEC strain was positive for the eae-gene, and O-groups associated with enterohemorrhagic E. coli (EHEC) types (O26, O103, O111, O145 and O157) were not found. Our report demonstrates that STEC are not frequent in urban children in Uganda, but domestic cattle were identified as an important natural reservoir for these organisms in this country.

Prevalence of aggressive periodontitis in school attendees in Uganda.

AIM: The prevalence and severity of early onset periodontitis (EOP) among students attending secondary schools in two regions of Uganda was studied. MATERIAL AND METHODS: 690 students (393 males and 297 females) aged 12-25 years (mean 17 years), representing a range of tribal groups, were recruited from six schools in the peri-urban Central and rural Western regions of Uganda. The study subjects were clinically examined in field conditions by a single calibrated examiner to measure gingival recession and probing depth at six sites per tooth, with subsequent calculation of clinical periodontal attachment level for each site. Subjects exhibiting >or= 4 mm of clinical periodontal attachment loss at approximal surfaces of one or more teeth were classified with EOP. A structured written questionnaire obtained demographic characteristics of the study subjects. RESULTS: 199 (28.8%) study subjects showed clinical features of EOP, of which 16 (2.3%) subjects exhibited generalized EOP, 29 (4.2%) localized EOP, and 154 (22.3%) incidental EOP. The percentage of EOP-affected males was significantly higher than females (33.8% vs. 22.2%, P < 0.001). EOP prevalence tended to increase with increasing age, but no association was found between EOP prevalence and socioeconomic status or residency in urban vs. rural areas of Uganda. Molars and mandibular incisors generally demonstrated the highest occurrence of >or= 4 mm attachment loss. Clinical periodontal attachment loss of >or= 5 mm was mainly seen at first molars and incisors, suggesting that these two tooth types are first affected with attachment loss. Approximal tooth surfaces showed greater probing depth and attachment loss than buccal and lingual surfaces. Gingival recession was most prevalent at mandibular anterior teeth, whereas gingival margin coronal to CEJ was most frequently observed at second molars and maxillary incisors. CONCLUSION: A relatively high prevalence of EOP (28.8%) was found in young Ugandan school attendees, with 6.5% of these showing severe disease. EOP in Uganda was significantly more prevalent in males than females, and most frequently characterized by approximal involvement of molars and mandibular incisors. Etiologic and predisposing factors associated with the high occurrence of EOP in Uganda, as well as therapeutic and preventive measures of the disease in this population, remain to be delineated.

Melarsoprol refractory T. b. gambiense from Omugo, north-western Uganda.

Culture adapted T. b. gambiense isolated from Northwest Uganda were exposed to 0.001-0.14 microg/ml melarsoprol or 1.56-100 microg/ml DL-alpha-difluoromethylornithine (DFMO). Minimum inhibitory concentrations (MICs) of each drug were scored for each isolate after a period of 10 days drug exposure. The results indicate that T. b. gambiense isolates from Northwest Uganda had elevated MIC values for melarsoprol ranging from 0.009 to 0.072 microg/ml as compared with T. b. gambiense isolates from Cote d'Ivoire with MIC values ranging from 0.001 to 0.018 microg/ml or with T. b. rhodesiense from Southeast Uganda with MIC values from 0.001 to 0.009 microg/ml. All MIC values obtained fell below expected peak melarsoprol concentrations in serum of treated patients. However, it may not be possible to maintain constant drug concentrations in serum of patients as was the case in our in vitro experiments. Importantly, the MIC of 0.072 microg/ml exhibited by one of the isolates from Northwest Uganda was above levels attainable in CSF indicating that this isolate would probably not be eliminated from CSF of treated patients. PCR amplification of the gene encoding the P2-like adenosine transporter followed by restriction digestion with Sfa NI enzyme revealed presence of fragments previously observed in a trypanosome clone with laboratory-induced arsenic resistance. From our findings it appears that reduced drug susceptibility may be one factor for the frequent relapses of sleeping sickness after melarsoprol treatment occurring in Northwest Uganda.
