Overt diabetes mellitus among newly diagnosed Ugandan tuberculosis patients: a cross sectional study.

BackgroundThere is a documented increase of diabetes mellitus in Sub Saharan Africa, a region where tuberculosis is highly endemic. Currently, diabetes mellitus is one of the recognised risk factors of tuberculosis. No study has reported the magnitude of diabetes mellitus among tuberculosis patients in Uganda, one of the countries with a high burden of tuberculosis.MethodsThis was a cross-sectional study conducted among 260 consenting adult patients with a confirmed diagnosis of tuberculosis admitted on the pulmonology wards of Mulago national referral and teaching hospital in Kampala, Uganda to determine the prevalence of diabetes mellitus and associated clinical factors. Laboratory findings as well as the socio-demographic and clinical data collected using a validated questionnaire was obtained. Point of care random blood sugar (RBS) testing was performed on all the patients prior to initiation of anti tuberculosis treatment. Diabetes mellitus was diagnosed if the RBS level was ≥ 200mg/dl in the presence of the classical symptoms of diabetes mellitus.ResultsThe prevalence of diabetes mellitus among the admitted patients with tuberculosis was 8.5%. Only 5 (1.9%) patients with TB had a known diagnosis of diabetes mellitus at enrolment. Majority of the study participants with TB-DM co-infection had type 2 diabetes mellitus (n=20, 90.9%).At bivariate analysis, raised mean ALT concentrations of ≥80 U/L were associated with DM (OR-6.1, 95% CI 1.4-26.36, p=0.032) and paradoxically, HIV co-infection was protective of DM (OR-0.32, 95% CI 0.13-0.79, P=0.016). The relationship between DM and HIV as well as that with ALT remained statistically significant at multivariate analysis (HIV: OR- 0.17 95%CI 0.06-0.51, p=0.002 and ALT: OR-11.42 95%CI 2.15-60.59, p=0.004).ConclusionThis study demonstrates that diabetes mellitus is common among hospitalized tuberculosis patients in Uganda. The significant clinical predictors associated with diabetes mellitus among tuberculosis patients were HIV co-infection and raised mean serum alanine transaminase concentrations.

The effect of blood storage age on treatment of lactic acidosis by transfusion in children with severe malarial anaemia: a pilot, randomized, controlled trial

BackgroundSevere malarial anaemia requiring blood transfusion is a life-threatening condition affecting millions of children in sub-Saharan Africa. Up to 40% of children with severe malarial anaemia have associated lactic acidosis. Lactic acidosis in these children is strongly associated with fatal outcomes and is corrected by blood transfusion. However, it is not known whether the storage age of blood for transfusion affects resolution of lactic acidosis. The objective of this pilot study was to evaluate the effect of blood storage age on resolution of lactic acidosis in children with severe malarial anaemia and demonstrate feasibility of conducting a large trial.MethodsChildren aged six to 59 months admitted to Acute Care Unit of Mulago Hospital (Kampala, Uganda) with severe malarial anaemia (haemoglobin ≤ 5 g/dL) and lactic acidosis (blood lactate ≥5 mmol/L), were randomly assigned to receive either blood of short storage age (one to 10 days) or long storage age (21–35 days) by gravity infusion. Seventy-four patients were enrolled and randomized to two equal-sized study arms. Physiological measurements, including blood lactate, oxygen saturation, haemoglobin, and vital signs, were taken at baseline, during and after transfusion. The primary outcome variable was the proportion of children whose lactic acidosis resolved by four hours after transfusion.ResultsThirty-four of 37 (92%) of the children in the short storage treatment arm compared to 30/37 (81%) in the long storage arm achieved a blood lactate <5 mmol/L by four hours post transfusion (p value = 0.308). The mean time to lactic acidosis resolution was 2.65 hours (95% CI; 2.25–3.05) in the short storage arm, compared to 3.35 hours (95% CI; 2.60–4.10) in the long storage arm (p value = 0.264).ConclusionPilot data suggest that among children with severe malarial anaemia and lactic acidosis transfused with packed red blood cells, the storage age of blood does not affect resolution of lactic acidosis. The results support a larger and well-powered study which is under way.Trial registrationclinicaltrials.gov NCT01580111

Perinatal death audits in a peri-urban hospital in Kampala, Uganda

The perinatal mortality of 70 deaths per 1,000 total births in Uganda is unacceptably high. Perinatal death audits are important for improvement of perinatal care and reduction of perinatal morality. We integrated perinatal death audits in routine care, and describe its effect on perinatal mortality rate at Nsambya Hospital. This was a retrospective descriptive study conducted from March - November 2008. An interdisciplinary hospital team conducted weekly perinatal death reviews. Each case was summarized and discussed, identifying gaps and cause of death. Local solutions were implemented according to the gaps identified from the audit process. Of the 350 perinatal deaths which occurred, 120 perinatal deaths were audited. 34.2% were macerated still births, 31.7% fresh still births and 34.2% early neonatal deaths. Avoidable factors included: poor neonatal resuscitation skills, incorrect use of the partographs and delay in performing caesarean sections. Activities implemented included: three skills sessions of neonatal resuscitation, introduction of Continuous positive airway pressure (CPAP) for babies with respiratory distress, updates on use of partographs. Perinatal mortality rate was 47.9 deaths per 1000 total births in 2008 after introduction of the audits compared to 52.8 per 1,000 total births in 2007. Conducting routine perinatal audits is feasible and contributes to reduction of facility perinatal mortality rate.

Inter-Relationships of Cardinal Features and Outcomes of Symptomatic Pediatric Plasmodium falciparum Malaria in 1,933 Children in Kampala, Uganda

Malaria remains a challenging diagnosis with variable clinical presentation and a wide spectrum of disease severity. Using a structured case report form, we prospectively assessed 1,933 children at Mulago Hospital in Kampala, Uganda with acute Plasmodium falciparum malaria. Children with uncomplicated malaria significantly differed from those with severe disease for 17 features. Among 855 children with severe disease, the case-fatality rate increased as the number of severity features increased. Logistic regression identified five factors independently associated with death: cerebral malaria, hypoxia, severe thrombocytopenia, leukocytosis, and lactic acidosis. Cluster analysis identified two groups: one combining anemia, splenomegaly, and leukocytosis; and a second group centered on death, severe thrombocytopenia, and lactic acidosis, which included cerebral malaria, hypoxia, hypoglycemia, and hyper-parasitemia. Our report updates previous clinical descriptions of severe malaria, quantifies significant clinical and laboratory inter-relationships, and will assist clinicians treating malaria and those planning or assessing future research (NCT00707200) (www.clinicaltrials.gov).

Surgery and Anesthesia Capacity‐Building in Resource‐Poor Settings: Description of an Ongoing Academic Partnership in Uganda

Surgery and perioperative care have been neglected in the arena of global health despite evidence of cost-effectiveness and the growing, substantial burden of surgical conditions. Various approaches to address the surgical disease crisis have been reported. This article describes the strategy of Global Partners in Anesthesia and Surgery (GPAS), an academically based, capacity-building collaboration between North American and Ugandan teaching institutions. The collaboration's projects shift away from the trainee exchange, equipment donation, and clinical service delivery models. Instead, it focuses on three locally identified objectives to improve surgical and perioperative care capacity in Uganda: workforce expansion, research, collaboration. Recruitment programs from 2007 to 2011 helped increase the number of surgery and anesthesia trainees at Mulago Hospital (Kampala, Uganda) from 20 to 40 and 2 to 19, respectively. All sponsored trainees successfully graduated and remained in the region. Postgraduate academic positions were created and filled to promote workforce retention. A local research agenda was developed, more than 15 collaborative, peer-reviewed papers have been published, and the first competitive research grant for a principal investigator in the Department of Surgery at Mulago was obtained. A local projects coordinator position and an annual conference were created and jointly funded by partnering international efforts to promote collaboration. Sub-Saharan Africa has profound unmet needs in surgery and perioperative care. This academically based model helped increase recruitment of trainees, expanded local research, and strengthened stakeholder collaboration in Uganda. Further analysis is underway to determine the impact on surgical disease burden and other important outcome measures.

AETIOLOGY, PATTERN AND MANAGEMENT OF ORAL AND MAXILLOFACIAL INJURIES AT MULAGO NATIONAL REFERRAL HOSPITAL.

To establish the aetiology, pattern and methods of management of oral and Maxillofacial injuries (OMFIs) seen at the Oral and Jaw injuries unit of Mulago National Referral Hospital (MNRH) Kampala, Uganda, over a ten year period. A descriptive retrospective study. Oral and jaw injury unit of Mulago National Referral Hospital, Kampala, Uganda. One thousand two hundred and three patient records met the inclusion. criteria. The age range was 1-90 years with a male: female ratio of 4.5:1. The age-group most affected was the 21-30-year-olds. Road traffic injuries (RTIs) were responsible for 61% (n = 735 of the injuries, interpersonal violence 27.6% (n = 332), accidental falls 12% (n = 142) and firearm injuries 2.2% (n = 27). Of the maxillofacial fractures (n = 1069) isolated mandibular fractures were 62%, isolated mid-facial fractures 24% whereas Pan-facial fractures accounted for 14%. The victims of OMFIs were mostly young men between 21 and 30 years of age. The main aetiological factors were road traffic injuries (RTIs) and interpersonal violence (IPV), while the lower third of the face was most often involved. Consistent with findings in other studies, RTI and IPV remain the two main causes of Maxillofacial injuries and public health measures targeting prevention should focus on these areas.

Evaluation of in-house PCR for diagnosis of smear-negative pulmonary tuberculosis in Kampala, Uganda

BackgroundNucleic acid amplification tests (NAATs) have offered hope for rapid diagnosis of tuberculosis (TB). However, their efficiency with smear-negative samples has not been widely studied in low income settings. Here, we evaluated in-house PCR assay for diagnosis of smear-negative TB using Lowenstein-Jensen (LJ) culture as the baseline test. Two hundred and five pulmonary TB (PTB) suspects with smear-negative sputum samples, admitted on a short stay emergency ward at Mulago Hospital in Kampala, Uganda, were enrolled. Two smear-negative sputum samples were obtained from each PTB suspect and processed simultaneously for identification of MTBC using in-house PCR and LJ culture.ResultsSeventy two PTB suspects (35%, 72/205) were LJ culture positive while 128 (62.4%, 128/205) were PCR-positive. The sensitivity and specificity of in-house PCR for diagnosis of smear-negative PTB were 75% (95% CI 62.6-85.0) and 35.9% (95% CI 27.2-45.3), respectively. The positive and negative predictive values were 39% (95% CI 30.4-48.2) and 72.4% (95% CI 59.1-83.3), respectively, while the positive and negative likelihood ratios were 1.17 (95% CI 0.96-1.42) and 0.70 (95% CI 0.43-1.14), respectively. One hundred and seventeen LJ culture-negative suspects (75 PCR-positive and 42 PCR-negative) were enrolled for follow-up at 2 months. Of the PCR-positive suspects, 45 (60%, 45/75) were still alive, of whom 29 (64.4%, 29/45) returned for the follow-up visit; 15 (20%, 15/75) suspects died while another 15 (20%, 15/75) were lost to follow-up. Of the 42 PCR-negative suspects, 22 (52.4%, 22/42) were still alive, of whom 16 (72.7%, 16/22) returned for follow-up; 11 (26.2%, 11/42) died while nine (21.4%, 9/42) were lost to follow-up. Overall, more PCR-positive suspects were diagnosed with PTB during follow-up visits but the difference was not statistically significant (27.6%, 8/29 vs. 25%, 4/16, p = 0.9239). Furthermore, mortality was higher for the PCR-negative suspects but the difference was also not statistically significant (26.2% vs. 20% p = 0.7094).ConclusionIn-house PCR correlates poorly with LJ culture for diagnosis of smear-negative PTB. Therefore, in-house PCR may not be adopted as an alternative to LJ culture.

Infection Control Knowledge, Attitudes, and Practices among Healthcare Workers at Mulago Hospital, Kampala, Uganda

Effective implementation of infection control programs and adherence to standard precautions are challenging in resource-limited settings. The objective of this study was to describe infection control knowledge, attitudes, and practices among healthcare workers (HCWs) in Uganda. We conducted a survey of hospital employees who had direct contact with patients or their immediate environment. We also performed an environmental assessment of resource availability and utilization within hospital wards. Surgical, medicine, and obstetrics wards at a national referral hospital in Kampala, Uganda. One hundred eighty-three randomly selected HCWs. Almost all HCWs knew to wash their hands, although nursing and support staff were less likely to perceive that HCWs' hands can be a vector of disease transmission. Hand washing was valued more as a means of self-protection than as a means to prevent patient-to-patient transmission, consistent with the prevailing belief that infection control was important for occupational safety. Sinks were not readily accessible, and soap at sinks was uncommon throughout the medicine and obstetrics wards but more commonly available in the surgery wards. Alcohol gel was rarely available. Changing infection control practices in developing countries will require a multifaceted approach that addresses resource availability, occupational safety, and local understanding and attitudes about infection control.

Oral Antimicrobial Rinse to Reduce Mycobacterial Culture Contamination among Tuberculosis Suspects in Uganda: A Prospective Study

RationaleContamination by bacterial or fungal organisms reduces the effectiveness of mycobacterial culture for diagnosis of pulmonary tuberculosis (TB). We evaluated the effect of an anti-microbial and an anti-fungal oral rinse prior to expectoration on culture-contamination rates.MethodsWe enrolled a consecutive random sample of adults with cough for ≥2 weeks and suspected TB admitted to Mulago Hospital (Kampala, Uganda) between October 2008 and June 2009. We randomly assigned patients to oral rinse (60 seconds with chlorhexidine followed by 60 seconds with nystatin) vs. no oral rinse prior to initial sputum collection. Uganda National Tuberculosis Reference Laboratory technicians blinded to the method of sputum collection (with or without oral rinse) processed all sputum specimens for smear microscopy (direct Ziehl-Neelsen) and mycobacterial culture (Lowenstein-Jensen media).ResultsOf 220 patients enrolled, 177 (80%) were HIV-seropositive (median CD4-count 37 cells/uL, IQR 13–171 cells/uL). Baseline characteristics were similar between patients in the oral-rinse (N = 110) and no oral-rinse (N = 110) groups. The proportion of contaminated cultures was significantly lower in the oral-rinse group compared to the no oral-rinse group (4% vs. 15%, risk difference −11%, 95% CI −18 to −3%, p = 0.005). Oral rinse significantly reduced the proportion of contaminated cultures among HIV-infected patients (3% vs. 18%, risk difference −14%, 95% CI −23 to −6%, p = 0.002) but not HIV-uninfected (6% vs. 4%, risk difference 2%, 95% CI −12 to +15%, p = 0.81) patients. However, the proportion of smear-positive specimens (25% vs. 35%, p = 0.10) and culture-positive specimens (48% vs. 56%, p = 0.24) were lower in the oral-rinse compared to the no oral-rinse group, although the differences were not statistically significant.ConclusionsOral rinse prior to sputum expectoration is a promising strategy to reduce mycobacterial culture contamination in areas with high HIV prevalence, if strategies can be devised to reduce the adverse impact of oral rinse on smear- and culture-positivity.

Reducing Data Entry Errors and Costs in a Clinical Laboratory in Uganda: Utilizing Six Sigma Quality Improvement Tools

The Makerere University-Johns Hopkins University Core Laboratory at the Infectious Disease Institute, Kampala, Uganda, provides clinical laboratory support to more than 70 research protocols, clinics, and hospitals in Kampala and surrounding rural areas. With increased numbers of clients and testing volume, the manual requisition data entry errors, at the preanalytic phase, have steadily increased, prompting laboratory management to …

Bronchoalveolar Lavage Enzyme-Linked Immunospot for Diagnosis of Smear-Negative Tuberculosis in HIV-Infected Patients

BackgroundPeripheral blood interferon-gamma release assays (IGRAs) have sub-optimal sensitivity and specificity for diagnosis of active pulmonary tuberculosis (TB). However, assessment of local immune responses has been reported to improve the accuracy of TB diagnosis.MethodsWe enrolled HIV-infected adults with cough ≥2 weeks’ duration admitted to Mulago Hospital in Kampala, Uganda and referred for bronchoscopy following two negative sputum acid-fast bacillus smears. We performed an ELISPOT-based IGRA (T-SPOT.TB®, Oxford Immunotec, Oxford, UK) using peripheral blood and bronchoalveolar lavage (BAL) fluid mononuclear cells, and determined the accuracy of IGRAs using mycobacterial culture results as a reference standard.Results94 HIV-infected patients with paired peripheral blood and BAL IGRA results were included. The study population was young (median age 34 years [IQR 28–40 years]) and had advanced HIV/AIDS (median CD4+ T-lymphocyte count 60 cells/µl [IQR 22–200 cells/µl]). The proportion of indeterminate IGRA results was higher in BAL fluid than in peripheral blood specimens (34% vs. 14%, difference 20%, 95% CI 7–33%, p = 0.002). BAL IGRA had moderate sensitivity (73%, 95% CI 50–89%) but poor specificity (48%, 95% CI 32–64%) for TB diagnosis. Sensitivity was similar (75%, 95% CI 57–89%) and specificity was higher (78%, 95% CI 63–88%) when IGRA was performed on peripheral blood.ConclusionsBAL IGRA performed poorly for the diagnosis of smear-negative TB in a high HIV/TB burden setting. Further studies are needed to examine reasons for the large proportion of indeterminate results and low specificity of BAL IGRA for active TB in high HIV/TB burden settings.

An Autopsy Study Describing Causes of Death and Comparing Clinico-Pathological Findings among Hospitalized Patients in Kampala, Uganda

BackgroundInformation on causes of death in HIV-infected patients in Sub-Saharan Africa is mainly derived from observational cohort and verbal autopsy studies. Autopsy is the gold standard to ascertain cause of death. We conducted an autopsy study to describe and compare the clinical and autopsy causes of death and contributory findings in hospitalized HIV-infected and HIV-uninfected patients in Uganda.MethodsBetween May and September 2009 a complete autopsy was performed on patients that died on a combined infectious diseases gastroenterology ward in Mulago Hospital in Kampala, Uganda. Autopsy cause of death and contributing findings were based on the macro- and microscopic post-mortem findings combined with clinical information. Clinical diagnoses were reported by the ward doctor and classified as confirmed, highly suspected, considered or not considered, based on information derived from the medical chart. Results are reported according to HIV serostatus.ResultsFifty-three complete autopsies were performed in 66% HIV-positive, 21% HIV-negative and 13% patients with an unknown HIV serological status. Infectious diseases caused death in 83% of HIV-positive patients, with disseminated TB as the main diagnosis causing 37% of deaths. The spectrum of illness and causes of death were substantially different between HIV-positive and HIV-negative patients. In HIV-positive patients 12% of postmortem diagnoses were clinically confirmed, 27% highly suspected, 16% considered and 45% not considered. In HIV-negative patients 17% of postmortem diagnoses were clinically highly suspected, 42% considered and 42% not considered.ConclusionAutopsy examination remains an important tool to ascertain causes of death particularly in settings with limited access to diagnostic testing during life. HIV-positive patients continue to die from treatable and clinically undiagnosed infectious diseases. Until rapid-point of care testing is available to confirm common infections, empiric treatment should be further investigated.

Evaluation of Capilia TB assay for rapid identification of Mycobacterium tuberculosis complex in BACTEC MGIT 960 and BACTEC 9120 blood cultures

BackgroundCapilia TB is a simple immunochromatographic assay based on the detection of MPB64 antigen specifically secreted by the Mycobacterium tuberculosis complex (MTC). Capilia TB was evaluated for rapid identification of MTC from BACTEC MGIT 960 and BACTEC 9120 systems in Kampala, Uganda. Since most studies have mainly dealt with respiratory samples, the performance of Capilia TB on blood culture samples was also evaluated.MethodsOne thousand samples from pulmonary and disseminated tuberculosis (TB) suspects admitted to the JCRC clinic and the TB wards at Old Mulago hospital in Kampala, Uganda, were cultured in automated BACTEC MGIT 960 and BACTEC 9120 blood culture systems. BACTEC-positive samples were screened for purity by sub-culturing on blood agar plates. Two hundred and fifty three (253) samples with Acid fast bacilli (AFB, 174 BACTEC MGIT 960 and 79 BACTEC 9120 blood cultures) were analyzed for presence of MTC using Capilia TB and in-house PCR assays.ResultsThe overall Sensitivity, Specificity, Positive and Negative Predictive values, and Kappa statistic for Capilia TB assay for identification of MTC were 98.4%, 97.6%, 97.7%, 98.4% and 0.96, respectively. Initially, the performance of in-house PCR on BACTEC 9120 blood cultures was poor (Sensitivity, Specificity, PPV, NPV and Kappa statistic of 100%, 29.3%,7%, 100% and 0.04, respectively) but improved upon sub-culturing on solid medium (Middlebrook 7H10) to 100%, 95.6%, 98.2%, 100% and 0.98, respectively. In contrast, the Sensitivity and Specificity of Capilia TB assay was 98.4% and 97.9%, respectively, both with BACTEC blood cultures and Middlebrook 7H10 cultured samples, revealing that Capilia was better than in-house PCR for identification of MTC in blood cultures. Additionally, Capilia TB was cheaper than in-house PCR for individual samples ($2.03 vs. $12.59, respectively), and was easier to perform with a shorter turnaround time (20 min vs. 480 min, respectively).ConclusionCapilia TB assay is faster and cheaper than in-house PCR for rapid identification of MTC from BACTEC MGIT 960 and BACTEC 9120 culture systems in real-time testing of AFB positive cultures.

Nasopharyngeal carriage rate of Streptococcus pneumoniae in Ugandan children with sickle cell disease

BackgroundNasopharyngeal carriage of Streptococcus pneumoniae is a determinant for invasive pneumococcal disease, which often complicates homozygous sickle cell disease. Here, we determined the nasopharyngeal carriage rate of S. pneumoniae in Ugandan children with homozygous sickle cell disease, who attended the outpatient Sickle Cell Clinic at Mulago National Referral hospital in Kampala, Uganda.ResultsS. pneumoniae occurred in 27 of the 81 children with homozygous sickle cell disease (giving a carriage rate of 33%, 27/81). Twenty three children were previously hospitalized of whom S. pneumoniae occurred in only two (9%, 2/23), while among the 58 who were not previously hospitalized it occurred in 25 (43%, 25/58, χ2 = 8.8, p = 0.003), meaning there is an association between high carriage rate and no hospitalization. Two children previously immunized with the pneumococcal conjugate vaccine did not carry the organism. Prior antimicrobial usage was reported in 53 children (65%, 53/81). There was high resistance of pneumococci to penicillin (100%, 27/27) and trimethoprime-sulfamethoxazole (97%, 26/27), but low resistance to other antimicrobials. Of the 70 children without sickle cell disease, S. pneumoniae occurred in 38 (54%, 38/70) of whom 43 were males and 27 females (53% males, 23/43, and 56% females, 15/27).ConclusionNasopharyngeal carriage of penicillin resistant pneumococci in Ugandan children with homozygous sickle cell disease is high. While nasopharyngeal carriage of S. pneumoniae is a determinant for invasive pneumococcal disease, pneumococcal bacteremia is reportedly low in Ugandan children with sickle cell disease. Studies on the contribution of high carriage rates to invasive pneumococcal disease in these children will be helpful. This is the first report on pneumococcal carriage rate in Ugandan children with sickle cell disease.

Characterizing Thyroid Disease and Identifying Barriers to Care and Treatment in Uganda

ABSTRACT Thyroid disease in Uganda continues to be endemic, despite national salt iodinization. This study describes the local characteristics of thyroid disease and identifies potential barriers to surgical access. A prospective database was established for all patients with suspected thyroid disease who presented to the Endocrine Surgery Clinic at Mulago National Referral Hospital in Kampala, Uganda in 2008. A cross-sectional study collected and analyzed for presentation, diagnostics and the surgical plan. A total of 89 patients were included, with an average age of 40 years, and 88% were women. The most common presentation was compressive symptoms (39%, n = 35), signs and symptoms of hyperthyroidism (30%, n = 27) and cosmetic concerns (16%, n = 14). Ultrasound, which is subsidized by the hospital, was performed in 85% of patients (n = 76). Thyroid function tests (TFTs), which are less subsidized, were done in 67% (n = 60). Of these, 27% (n = 16) were hyperthyroid and 7% (n = 4) were hypothyroid. Fine needle aspiration was done in 30% (n = 27) and were suspicious for malignancy in 27% of patients (n = 7). The most common diagnosis was multinodular goiter (n = 55) and tracheal compression or deviation and/or retrosternal extension was seen on imaging in 22 of 75 patients (29%). Thyroid disease in Uganda is more advanced, involves a different population than in Western countries and includes high rates of symptomatic multinodular goiter and cancer. Resource constraints limit the care of these clinically challenging conditions. Further evaluation of these potential barriers to surgical care needs to be conducted.

A descriptive epidemiological study on stroke in Kampala, Uganda: a hospitalbased study

Background Basic stroke features are hardly known in sub-Saharan countries, and no data are available in Uganda. Objective To characterize patients presenting with clinical stroke to Mulago Hospital. Design Descriptive epidemiological study. Setting Mulago National referral Hospital in Kampala, Uganda. Participants Patients presenting with clinical stroke from 1st July to 30th November 2006. Patients with confirmed stroke had comprehensive assessments for stroke risk factors. Results Among 139 patients presenting with clinical stroke, 127 had a non-contrast head CT scan and 12 died prior to scan. Eighty five patients were confirmed to have stroke while 42 had non stroke lesions. Among patients with confirmed stroke, 77.6% had ischemic stroke while 22.4% had hemorrhagic stroke. The mean age for all stroke patients was 62.2 ± 16.2 yrs and 51.8% were men. The incidence of both ischemic and hemorrhagic stroke increased with age. Atherosclerotic stroke was the most common ischemic stroke etiology, observed in 43.5% patients with ischemic stroke, while intraparenchymal hemorrhage was the most common hemorrhagic stroke etiology, observed in 78.9% of patients with hemorrhagic stroke. Hypertension was the commonest risk factor with more than 50% of all stroke patients reporting a history of hypertension, and more than half found to have blood pressure greater than 140/90 mm Hg. Physical inactivity and hypercholesterolemia were encountered in more than 36% and 30% of patients with ischemic and haemorrhagic strokes respectively.

The Role of Speciation in Positive Lowenstein-Jensen Culture Isolates from a High Tuberculosis Burden Country

ObjectiveTo determine the need for routine speciation of positive Lowenstein-Jensen mycobacterial cultures in HIV-infected patients suspected of having pulmonary tuberculosis at Mulago Hospital in Kampala, Uganda.MethodsSputum and bronchoalveolar lavage Lowenstein-Jensen mycobacterial culture isolates from consecutive, HIV-infected patients admitted to Mulago Hospital with 2 weeks or more of cough were subjected to IS6110 PCR and rpoB genetic analysis to determine the presence of Mycobacterium tuberculosis complex (MTBC) and non-tuberculous mycobacteria (NTM).ResultsEighty (100%) mycobacterial cultures from 65 patients were confirmed to be members of MTBC. Subsequent analysis of the cultures from 54 patients by PCR and sequence analyses to identify co-infection with NTM confirmed the presence of MTBC as well as the presence of Micrococcus luteus (n = 4), Janibacter spp. (n = 1) and six cultures had organisms that could not be identified.ConclusionsPresumptive diagnosis of tuberculosis on the basis of a positive Lowenstein-Jensen culture is sufficient in HIV-infected Ugandans suspected of having tuberculosis. Routine molecular confirmation of positive Lowenstein-Jensen cultures is unnecessary in this low resource setting.

Predictors of treatment failure among pulmonary tuberculosis patients in Mulago hospital, Uganda

Early identification of Tuberculosis (TB) treatment failure using cost effective means is urgently needed in developing nations. The study set out to describe affordable predictors of TB treatment failure in an African setting. To determine the predictors of treatment failure among patients with sputum smear positive pulmonary TB at Mulago hospital. The study was carried out in the TB clinic of Mulago hospital Kampala, Uganda. This was an unmatched case control study where fifty patients with a diagnosis of TB treatment failure (cases) and 100 patients declared cured after completing anti TB treatment (controls) were recruited into the study. Cases were compared with controls to determine predictors of treatment failure. Significant predictors of treatment failure in this study included a positive sputum smear at 2 months of TB treatment (OR 20.63, 95%CI 5.42- 78.41) and poor adherence to anti TB treatment (OR 14.59, 95%CI 3.04-70.15). This study identified a treatment related and a simple laboratory predictor of TB treatment failure in Mulago hospital which may be used in resource limited settings for early recognition of those at risk and early intervention.
