(Journal of Pediatric Infectious Diseases, 2008) Bakeera-Kitakaa, Sabrina; McKellar, Mehri; Snider, Cynthia; Kekitiinwa, Adeodata; Piloya, Theresa; Ronald, Allan; Marjan, Javanbakht; Colebunders, Robert
Abstract. There is a paucity of knowledge about perinatally infected human immunodeficiency virus (HIV) positive children surviving into their adolescent years, especially from sub-Saharan Africa. Although studies have described the effects of the disease on the physical and sexual maturation of this population, their response to highly active antiretroviral therapy has not been systematically studied. At the pediatric infectious diseases clinic in Mulago hospital, Kampala, Uganda, we evaluated the effect of antiretroviral therapy (ART) on 118 treatment-naive, perinatally-infected HIV positive adolescents between the ages of 10–19 for 12 months. We monitored physical growth using The Centers for Disease Control and Prevention and recently published World Health Organization (WHO) reference growth standards for height and weight measurements as well as sexual maturation using Tanner staging. Laboratory tests including: complete blood count, absolute CD4 cell count and percentage, and HIV-1 RNA viral load, were performed at baseline and at 3-month intervals. Of 118 children, 64% were female; the median age was 13.6 years old. At baseline, 75% were classified as WHO clinical stages III and IV, with a median CD4 count of 124 cells/ul. Apart from four adolescents, all were on first-line antiretroviral therapy with 2 nucleoside reverse transcriptase inhibitors and 1 non-nucleoside reverse transcriptase inhibitors. After 6 months, the median CD4 count was 304 cells/μL, increasing to 370 cells/μL, by 12 months. Antiretroviral therapy was virologically suppressive (HIV-1 RNA viral load <400 copies/mL) in 79% of the adolescents at 6 months and in 89% at 12 months. Six (5%) patients died during the 12-month study. The median baseline height for age Z score was −2.41 which improved to a median of −1.96 by 12 months (P < 0.0001). The median baseline weight for age Z score was −2.61 and improved to −1.26 by 12 months (P < 0.0001). The median body mass index Z score increased from −1.39 to −0.47 by 12 months (P < 0.0001). At baseline, 63% of the adolescents were noted to have delayed pubertal maturation; this only reduced slightly to 60% after 12 months. Adolescents with predominantly perinatally-acquired HIV infection and significant disease burden showed appropriate virologic and immunological response to ART in addition to having clinically significant improvements in growth and some improvement in sexual maturation.
Disease diagnosis in primary care in Uganda
(BMC Family Practice, 2014) Kayitale Mbonye, Martin; Burnett, Sarah M.; Colebunders, Robert; Naikoba, Sarah; Van Geertruyden, Jean-Pierre; Weaver, Marcia R.; Ronald, Allan
The overall burden of disease (BOD) especially for infectious diseases is higher in Sub-Saharan Africa than other regions of the world. Existing data collected through the Health Management Information System (HMIS) may not be optimal to measure BOD. The Infectious Diseases Capacity Building Evaluation (IDCAP) cooperated with the Ugandan Ministry of Health to improve the quality of HMIS data. We describe diagnoses with associated clinical assessments and laboratory investigations of outpatients attending primary care in Uganda. Methods: IDCAP supported HMIS data collection at 36 health center IVs in Uganda for five months (November 2009 to March 2010) prior to implementation of the IDCAP interventions. Descriptive analyses were performed on a cross-sectional dataset of 209,734 outpatient visits during this period. Results: Over 500 illnesses were diagnosed. Infectious diseases accounted for 76.3% of these and over 30% of visits resulted in multiple diagnoses. Malaria (48.3%), cough/cold (19.4%), and intestinal worms (6.6%) were the most frequently diagnosed illnesses. Body weight was recorded for 36.8% of patients and less than 10% had other clinical assessments recorded. Malaria smears (64.2%) and HIV tests (12.2%) accounted for the majority of 84,638 laboratory tests ordered. Fewer than 30% of patients for whom a laboratory investigation was available to confirm the clinical impression had the specific test performed. Conclusions: We observed a broad range of diagnoses, a high percentage of multiple diagnoses including true co-morbidities, and underutilization of laboratory support. This emphasizes the complexity of illnesses to be addressed by primary healthcare workers. An improved HMIS collecting timely, quality data is needed. This would adequately describe the burden of disease and processes of care at primary care level, enable appropriate national guidelines, programs and policies and improve accountability for the quality of care.
Effect of Integrated Capacity-Building Interventions on Malaria Case Management by Health Professionals in Uganda: A Mixed Design Study with Pre/Post and Cluster Randomized Trial Components
(PloS one, 2014) Kayitale Mbonye, Martin; Burnett, Sarah M.; Burua, Aldomoro; Colebunders, Robert; Crozier, Ian; Kinoti, Stephen N.; Ronald, Allan; Naikoba, Sarah; Rubashembusya, Timothy; Van geertruyden, Jean-Pierre; Willis, Kelly S.; Weaver, Marcia R.
The Integrated Infectious Diseases Capacity Building Evaluation (IDCAP) designed two interventions: Integrated Management of Infectious Disease (IMID) training program and On-Site Support (OSS). We evaluated their effects on 23 facility performance indicators, including malaria case management. Methodology: IMID, a three-week training with two follow-up booster courses, was for two mid- level practitioners, primarily clinical officers and registered nurses, from 36 primary care facilities. OSS was two days of training and continuous quality improvement activities for nine months at 18 facilities, to which all health workers were invited to participate. Facilities were randomized as clusters 1:1 to parallel OSS ‘‘arm A’’ or control ‘‘arm B’’. Outpatient data on four malaria case management indicators were collected for 14 months. Analysis compared changes before and during the interventions within arms (relative risk = RR). The effect of OSS was measured with the difference in changes across arms (ratio of RR = RRR). Findings: The proportion of patients with suspected malaria for whom a diagnostic test result for malaria was recorded decreased in arm B (adjusted RR (aRR) = 0.97; 99%CI: 0.82,1.14) during IMID, but increased 25% in arm A (aRR = 1.25; 99%CI:0.94, 1.65) during IMID and OSS relative to baseline; (aRRR = 1.28; 99%CI:0.93, 1.78). The estimated proportion of patients that received an appropriate antimalarial among those prescribed any antimalarial increased in arm B (aRR = 1.09; 99%CI: 0.87, 1.36) and arm A (aRR = 1.50; 99%CI: 1.04, 2.17); (aRRR = 1.38; 99%CI: 0.89, 2.13). The proportion of patients with a negative diagnostic test result for malaria prescribed an antimalarial decreased in arm B (aRR = 0.96; 99%CI: 0.84, 1.10) and arm A (aRR = 0.67; 99%CI: 0.46, 0.97); (aRRR = 0.70; 99%CI: 0.48, 1.00). The proportion of patients with a positive diagnostic test result for malaria prescribed an antibiotic did not change significantly in either arm.
Effectiveness of educational outreach in infectious diseases management: a cluster randomized trial in Uganda
(BMC Public Health, 2016) Kayitale Mbonye, Martin; Burnett, Sarah M.; Naikoba, Sarah; Ronald, Allan; Colebunders, Robert; Van Geertruyden, Jean-Pierre; Weaver, Marcia R.
Integrated Infectious Diseases Capacity Building Evaluation (IDCAP) teams designed and implemented two health worker in-service training approaches: 1) an off-site classroom-based integrated management of infectious diseases (IMID) course with distance learning aspects, and 2) on-site support (OSS), an educational outreach intervention. We tested the effects of OSS on workload and 12 facility performance indicators for emergency triage assessment and treatment, HIV testing, and malaria and pneumonia case management among outpatients by two subgroups: 1) mid-level practitioners (MLP) who attended IMID training (IMID-MLP) and 2) health workers who did not (No-IMID). Methods: Thirty-six health facilities participated in the IDCAP trial, with 18 randomly assigned to Arm A and 18 to Arm B. Two MLP in both arms received IMID. All providers at Arm A facilities received nine monthly OSS visits from April to December 2010 while Arm B did not. From November 2009 to December 2010, 777,667 outpatient visits occurred. We analyzed 669,580 (86.1 %) outpatient visits, where provider cadre was reported. Treatment was provided by 64 IMID-MLP and 1,515 No-IMID providers. The effect of OSS was measured by the difference in pre/post changes across arms after controlling for covariates (adjusted ratio of relative risks = aRRR). Results: The effect of OSS on patients-per-provider-per-day (workload) among IMID-MLP (aRRR = 1.21; p = 0.48) and No-IMID (aRRR = 0.90; p = 0.44) was not statistically significant. Among IMID-MLP, OSS was effective for three indicators: malaria cases receiving an appropriate antimalarial (aRRR = 1.26, 99 % CI = 1.02-1.56), patients with negative malaria test result prescribed an antimalarial (aRRR = 0.49, 99 % CI = 0.26-0.92), and patients with acid-fast bacilli smear negative result receiving empiric treatment for acute respiratory infection (aRRR = 2.04, 99 % CI = 1.06-3.94). Among No-IMID, OSS was effective for two indicators: emergency and priority patients admitted, detained or referred (aRRR = 2.12, 99 % CI = 1.05-4.28) and emergency patients receiving at least one appropriate treatment (aRRR = 1.98, 99 % CI = 1.21-3.24). Conclusion: Effects of OSS on workload were not statistically significant. Significant OSS effects on facility performance across subgroups were heterogeneous. OSS supported MLP who diagnosed and treated patients to apply IMID knowledge. For other providers, OSS supported team work to manage emergency patients. This evidence on OSS effectiveness could inform interventions to improve health workers’ capacity to deliver better quality infectious diseases care.
HIV Counseling and Testing Practices at an Urban Hospital in Kampala, Uganda
(AIDS and Behavior, 2006) Wanyenze, Rhoda K.; Kamya, Moses R.; Liechty, Cheryl A.; Ronald, Allan; Guzman, David J.; Wabwire-Mangen, Fred; Mayanja-Kizza, Harriet; Bangsberg, David R.
While the majority of medical inpatients in Uganda are assumed to be HIV-positive, HIV testing is limited in inpatient settings. This study describes HIV testing practices and risk behavior among medical inpatients at an urban hospital in Uganda. We interviewed 395 adults on the day of discharge. Overall, 46% tested for HIV before or during admission. Of the 20% tested during hospitalization, 64% were HIV-positive. Among 47% who had sex in the previous year, only 14% used condoms consistently and only 20% knew the HIV status of their sexual partner, indicating that participants would benefit from risk-reduction counseling. Yet, only 26% of participants tested during hospitalization received post-test counseling. Half of the participants with HIV-related illnesses left the hospital without being offered the test, a missed opportunity for HIV prevention counseling and care. The findings indicate that hospitals are important venues for HIV counseling and testing.
Linkage to HIV Care and Survival Following Inpatient HIV Counseling and Testing
(AIDS and Behavior, 2011) Wanyenze, Rhoda K.; Hahn, Judith A.; Liechty, Cheryl A.; Ragland, Kathie; Ronald, Allan; Mayanja-Kizza, Harriet; Coates, Thomas; Kamya, Moses R.; Bangsberg, David R.
Linkage to HIV care and survival in sub-Saharan Africa is not well documented. In 2004 we conducted a randomized trial among medical inpatients in Mulago Hospital to assess the impact of HIV counseling and testing (HCT) on linkage to care and survival. Participants were randomized to inpatient HCT (intervention) or outpatient HCT 1 week post-discharge (control); inpatient HCT was not available at Mulago during the study. Among 590 eligible patients, 85% (500) agreed to participate; 98.8% (248) in the intervention arm received HCT compared to 68.7% (171) in the control arm. Within 6 months, 62.2% (92) of surviving HIV-infected participants received HIV care; 15.0% (20) received antiretroviral medications (ARVs). Overall mortality among HIV infected participants was 34.6% (72). HCT had significant impact on linkage to care among surviving participants. Referral for HCT was a missed opportunity for diagnosis. There is need for earlier diagnosis and linkage to HIV care among inpatients.
The liver in HIV in Africa
(International Medical Press, 2005) Feld, Jordan J; Ocama, Ponsiano; Ronald, Allan
As access to antiretroviral therapy improves across the African continent, liver disease is emerging as an important cause of morbidity and mortality among HIV-infected individuals. Although coinfection with hepatitis B virus (HBV) and hepatitis C virus (HCV), along with highly active antiretroviral therapy (HAART)induced hepatotoxicity appear to be the major causes of liver disease in this population, other diseases endemic to Africa with hepatic manifestations are influenced by HIV infection as well. In this review we present the available data on liver disease in HIV-infected populations in Africa and discuss relevant data from the rest of the world. In addition, we highlight important areas for further study
Measuring the Outcomes of a Comprehensive HIV Care Course
(JAIDS Journal of Acquired Immune Deficiency Syndromes, 2006) Weaver, Marcia R.; Nakitto, Cecilia; Schneider, Gisela; Kamya, Moses R.; Kambugu, Andrew; Lukwago, Robinah; Ronald, Allan; McAdam, Keith; Sande, Merle A.
To evaluate the effects of the Infectious Diseases Institute's 4-week course for African doctors on comprehensive management of HIV including antiretroviral therapy on four outcomes: (1) clinical skills, (2) clinical activities, (3) monitoring of HIV patients, and (4) training activities Clinical exam at beginning and end of course and at follow-up 3 to 4 months later, and a cross-section telephone survey. Forty-seven doctors attending the course (October 2004, November 2004, March 2005, and April 2005) agreed to participate. A 17-item Clinical Exam Checklist was used to assess clinical skills. A telephone survey was conducted 1 month after the course to collect data in four areas: clinical activities, monitoring of HIV patients, case studies on initiation of ART, and training activities. The course improved the clinical skills of doctors. Between the beginning and end of the course, their clinical skills improved significantly in 11 of 17 areas (n = 34). Between the end of the course and follow-up, their skills improved significantly in three areas (n = 14). The trainees were practicing HIV care and training. The telephone survey (n = 46) showed that 93% of trainees treated HIV patients, 35% provided training on HIV, and 47% monitored the weight of the last HIV patient treated (patient's weight was a clinical end point to measure health status). At follow-up, everyone provided training and trained an average of 20 people per month.
The spectrum of liver diseases in HIV infected individuals at an HIV treatment clinic in Kampala, Uganda
(African health sciences, 2008) Ocama, Ponsiano; Katwere, Michael; Piloya, Theresa; Feld, Jordan; Opio, Kenneth C.; Kambugu, Andrew; Katabira, Elly; Thomas, David; Colebunders, Robert; Ronald, Allan
Liver diseases are common in patients with HIV due to viral hepatitis B and C co-infections, opportunistic infections or malignancies, antiretroviral drugs and drugs for opportunistic infections. Objective: To describe the spectrum of liver diseases in HIV-infected patients attending an HIV clinic in Kampala, Uganda. Method: Consecutive patients presenting with jaundice, right upper quadrant pain with fever or malaise, ascites and/or tender hepatomegaly were recruited and underwent investigations to evaluate the cause of their liver disease. Results: Seventy-seven consecutive patients were recruited over an eleven month period. Of these, 23 (30%) had increased transaminases because of nevirapine (NVP) and/or isoniazid (INH) hepatotoxicity. Although 14 (61%) patients with drug-induced liver disease presented with jaundice, all recovered with drug discontinuation. Hepatitis B surface antigen was positive in 11 (15%) patients while anti-hepatitis C antibody was reactive in only 2 (3%). Probable granulomatous hepatitis due to tuberculosis was diagnosed in 7 (9%) patients and all responded to anti-TB therapy. Other diagnoses included alcoholic liver disease, AIDS cholangiopathy, hepatocellular carcinoma, schistosomiasis, haemangioma and hepatic adenoma. Twelve (16%) patients died during follow-up of which 7 (9%) died because of liver disease. Conclusion: Drug history, liver enzyme studies, ultrasound, and hepatitis B and C investigations identified the probable etiology in 60 (78%) of 77 patients with HIV infection presenting with symptoms and/or signs of liver disease.
