Rubella IgM epidemiology in the pre-rubella vaccination era in Uganda.

BACKGROUND: Control of Rubella and Congenital Rubella Syndrome using vaccination has shown great success in the America's. Uganda is due to introduce the Rubella vaccine however the magnitude of transmission is not well documented. Therefore this study was done to determine IgM sero-prevalance for Rubella in order to help monitor vaccine effectiveness post introduction of the vaccine in routine vaccination programme. METHODS: A retrospective review of suspected measles cases data for the reporting period January 2007 to December 2016 in Uganda was Done. rubella IgM testing was done on 15,296 of the cases and the data was analyzed using STATA version 13. RESULTS: In total 15,296 cases were tested and 4255 (27.8%) tested positive and among females aged 15-49 years 88 out of 322 (27%) tested positive. The age distribution range was 0-80 years, rubella IgM positivity was reported in all the 15 regions of Uganda and throughout the ten year period in every month. Age group 5-15 years had OR 2.5 p-value < 0.001 of being rubella IgM positive compared to age < 5 years and testing measles IgM negative OR 6.3 p-value < 0.001. CONCLUSION: Rubella is endemic in Uganda and although rubella IgM positivity is highest in the age 5-15 years even the younger, older and women of reprodutive age are affected. This means the risk of Congenital Rubella Syndrome is high hence the need to introduce the rubella vaccine for infants and pregnant mothers and continued surveillance to enhance its control.

Prevalence, Morphological Classification, And Factors Associated With Anemia Among Pregnant Women Accessing Antenatal Clinic At Itojo Hospital, South Western Uganda.

PURPOSE: The study aimed to determine the prevalence, morphological classification, and risk factors of anemia among pregnant mothers attending antenatal clinic at Itojo hospital, Ntungamo district, southwestern Uganda. PATIENTS AND METHODS: After obtaining an informed consent, 5mL of blood was collected from the vein of each participant for complete blood count (CBC) and peripheral film report. The CBC was performed using HumaCount 80 hematology analyzer (HUMAN Gesellschaft für Biochemica und Diagnostica mbH Max-Planck-Ring 21 65,205 Wiesbaden Germany). Peripheral blood smears were made and stained using Wright's Romanowsky stain and examined under ×1000 magnification for morphological classification of anemia. Structured questionnaires were administered to each participant to collect information on patients' demography and risk factors of anaemia in pregnancy. The data generated were prepared in EXCEL and later transferred to SPSS version 20 for analysis. Univariate logistic regression and multivariate logistic regression were used to evaluate the association of socio-demographic characteristics of the participants with anemia. A 95% confidence level was used and statistical significance was reached at p<0.05. RESULTS: One hundred and sixty-three participants (n=163) were recruited for the study with the median age of 25 years and range of (17 to 40 years). The overall prevalence of anemia was 12 (7.4%), the morphological classification was 1 (8.3%) normocytic normochromic anemia, 6 (50%) microcytic hypochromic anemia, and 5 (41.7%) macrocytic anemia. Spouse occupation (p=0.03), household income (p=0.04), use of insecticide-treated mosquito nets (p=0.001), history of urinary tract infection (p=0.002), use of haematinics (p≤0.001), and history of postpartum hemorrhage (p=0.03) were significantly associated with anemia in pregnancy. CONCLUSION: Despite the reported high prevalence of anemia in pregnancy in other areas within the country, anemia prevalence was low in this study. Routine screening for anemia at all antenatal care clinics countrywide is recommended.

Antimicrobial resistance in pathogenic aerobic bacteria causing surgical site infections in Mbarara regional referral hospital, Southwestern Uganda.

Surgical site infections (SSI) remain a common postoperative complication despite use of prophylactic antibiotics and other preventive measures, mainly due to increasing antimicrobial resistance. Here, we present antimicrobial resistance rate of bacteria isolated in clinical cases of SSI. A hospital based descriptive cross sectional study was conducted on 83 consented postoperative patients with clinical SSI. Data on patients was obtained using structured data collection form. Two swabs were collected aseptically from each patient. Bacteriological culture examination and identification was done following standard microbiological techniques. Antibiotic susceptibility test was done by Kirby-Bauer disc diffusion method. Gram negative bacteria (GNB) were predominant (65.59%) with the dominant being Klebsiella species (29.03%). Overall 86% of aerobic bacteria isolated were multidrug resistant (MDR) where 65.63% and 96.72% of Gram positive and Gram negative isolates were MDR respectively. All the isolates with exception of Enterococci species were resistant to ampicillin. GNB showed high resistance to ceftriaxone, sulfamethoxazole/trimethoprim and gentamicin. All the isolated Klebsiella spp were MDR. S. aureus were all resistant to oxacillin. The isolation rate was higher in emergency, males and dirty wounds in relation to nature of surgery, gender and class of surgical wound respectively. These findings necessitate judicious antibiotic use and calls for surveillance of SSIs periodically as well as strict adherence to good sanitation practice to reduce spread of drug-resistant pathogens.

Prevalence and Risk Factors of Helicobacter pylori Infection among Children Aged 1 to 15 Years at Holy Innocents Children's Hospital, Mbarara, South Western Uganda.

BACKGROUND: Helicobacter pylori infection affects more than half of the world's population. The infection is generally acquired during childhood but can remain asymptomatic, with long-term clinical sequelae including gastritis, peptic ulcer disease, and stomach cancer. METHODS: The study was approved by Institutional Review Committee of Mbarara University of Science and Technology. After obtaining informed consent from parents/legal guardians, illegible children who presented with gastrointestinal complaints at Holy Innocents Children's Hospital were recruited; structured questionnaires were administered to the parents/guardians to collect information on sociodemographic data and risk factors of H. pylori infection. Four (4) millilitres of blood was collected from each child and tested for H. pylori blood Antibody test and stool specimens were used for H. pylori antigen test. RESULTS: The prevalence of H. pylori infection among the study participants was 24.3%. The infection rate increased with increase in age of the participants, from 16.2% among 1to 5 years old to 27.2% among 6 to 10 years. Infections were higher among school going children (68/74, p=0.003, OR 3.9; CI: 1.5 to 10.6) and children from crowded households (59/74, p<0.001, OR 2.6, and CI 1.3 to 5.0), unsafe source of drinking water at schools (46/74, p=0.003), and lack of sanitary facility at homes (57/74, p=0.001, and OR 1.6 CI 0.7 to 3.6). CONCLUSION: The prevalence of H. pylori infection among children aged 1 to 15 years at Holy Innocents Children's Hospital was high and increases with age. School attendance, lack of sanitary facility, lack of safe drinking water, and overcrowding were the risk factors associated with H. pylori infection.

Water, Sanitation, and Hygiene Service Availability at Rural Health Care Facilities in Southwestern Uganda.

There is a paucity of information on the state of water, sanitation, and hygiene (WASH) at health care facilities in Uganda. A survey on WASH service availability was conducted at 50 health care facilities across 4 districts of rural southwestern Uganda between September and November 2015. The main water points at the majority (94%) of the health care facilities were improved sources, while improved toilets were available at 96% of the health care facilities visited. Hospitals had the poorest toilet to patient ratio (1 : 63). Only 38% of the health care facilities had hand washing facilities at the toilets. The lack of hand washing facilities was most prominent at the level IV health centre toilets (71%). Hand washing facilities were available at other points within most (76%) of the health care facilities. However, both water and soap were present at only 24% of these health care facilities. The poor toilet to patient/caregiver ratios particularly in the high volume health care facilities calls for the provision of cheaper options for improved sanitation in these settings. Priority should also be given to the sustainable provision of hygiene amenities such as soap for hand washing particularly the high patient volume health care facilities, in this case the level IV health centres and hospitals.

ABO and Rhesus (D) blood group distribution among blood donors in rural south western Uganda: a retrospective study.

BACKGROUND: In Uganda, geographical distribution of blood groups and Rhesus (D) factor varies across the country. The aim of this study was to examine the distribution of these groups among voluntary blood donors in rural southwestern Uganda. RESULTS: Twenty-three thousand five hundred four (23,504) blood donors were included in the study. The donors had a mean age of 21 years (SD ± 5.7) and were mainly male (73%). The distribution of ABO blood group was; blood group O (50.3%); blood group A (24.6%); blood group B (20.7%) and blood group AB (4.5%). The proportions of Rhesus (D) positive and Rhesus (D) negative were 98 and 2% respectively. The proportion of non-adult donors (<18 years) was significantly higher among the female than the male donors (p value <0.001). A significantly higher proportion of males than females were Rhesus (D) negative (p-value <0.001). No significant relationship was found between age and blood group distribution. CONCLUSION: The sequence of ABO distribution among the rural population in southwestern Uganda is; O > A > B > AB, with males as the predominant donors. The frequency of Rhesus (D) negative is very low in rural southwestern Ugandan and is mainly among males. The blood bank services in southwestern Uganda need to develop innovative strategies targeting female donors who are more likely to boost blood stocks in the region.
