Contraceptive counseling experiences among women attending HIV care and treatment centers: A national survey in Kenya

OBJECTIVES

To characterize contraceptive counseling experiences among women living with HIV (WLWH) receiving HIV care in Kenya.

STUDY DESIGN

Sexually active, WLWH aged 15 to 49 years were purposively sampled from 109 high-volume HIV Care and Treatment Centers in Kenya between June and September 2016. Cross-sectional surveys were administered to enroll women on a tablet using Open Data Kit. Poisson generalized linear regression models adjusted for facility-level clustering were used to examine cofactors for receiving family planning (FP) counseling with a provider.

RESULTS

Overall, 4805 WLWH were enrolled, 60% reported they received FP counseling during the last year, 72% of whom reported they were counseled about benefits of birth spacing and limiting. Most women who received FP counseling were married (64%) and discussed FP with their partner (78%). Use of FP in the last month (adjusted Prevalence Ratio [aPR] = 1.74, 95% confidence interval [CI]: 1.41-2.15, p < 0.001), desire for children in >2 years (aPR = 1.18, 95% CI: 1.09-1.28, p < 0.001), and concern about contraceptive side-effects (aPR = 1.13, 95% CI 1.02-1.25, p < 0.05) were significantly higher among WLWH who received FP counseling compared to those that did not.

CONCLUSIONS

Over one-third of WLWH did not receiving FP counseling with an HIV care provider during the last year, and counseling was more commonly reported among women who were using FP or desired children in >2 years.

IMPLICATIONS

There are missed opportunities for FP counseling in HIV care. FP integration in HIV care could improve FP access and birth spacing or limiting among WLWH.

“They Just Tell Me to Abstain:” Variable Access to and Uptake of Sexual and Reproductive Health Services Among Adolescents Living With HIV in Kenya

Background: To improve holistic care for adolescents living with HIV (ALHIV), including integration of sexual and reproductive health services (SRHS), the Kenya Ministry of Health implemented an adolescent package of care (APOC). To inform optimized SRH service delivery, we sought to understand the experiences with SRHS for ALHIV, their primary caregivers, and health care workers (HCWs) following APOC implementation.

Methods: We completed a mixed methods evaluation to characterize SRHS provided and personal experiences with access and uptake using surveys conducted with facility managers from 102 randomly selected large HIV treatment facilities throughout Kenya. Among a subset of 4 APOC-trained facilities in a high burden county, we conducted in-depth interviews (IDIs) with 40 ALHIV and 40 caregivers of ALHIV, and 4 focus group discussions (FGDs) with HCWs. Qualitative data was analyzed using thematic analysis. Facility survey data was analyzed using descriptive statistics.

Results: Of 102 surveyed facilities, only 56% reported training in APOC and 12% reported receiving additional adolescent-related SRHS training outside of APOC. Frequency of condom provision to ALHIV varied, with 65% of facilities providing condoms daily and 11% never providing condoms to ALHIV. Family planning (FP) was provided to ALHIV daily in 60% of facilities, whereas 14% of facilities reported not providing any FP services to ALHIV. Screening and treatment for STIs for adolescents were provided at all clinics, with 67% providing STI services daily. Three key themes emerged characterizing experiences with adolescent SRHS access and uptake: (1) HCWs were the preferred source for SRH information, (2) greater adolescent autonomy was a facilitator of SRH discussions with HCWs, and (3) ALHIV had variable access to and limited uptake of SRHS within APOC-trained health facilities. The primary SRHS reported available to ALHIV were abstinence and condom use education. There was variable access to FP, condoms, pregnancy and STI testing, and partner services. Adolescents reported limited utilization of SRHS beyond education.

Conclusions: Our results indicate a gap in SRHS offered within APOC trained facilities and highlight the importance of adolescent autonomy when providing SRHS and further HCW training to improve SRHS integration within HIV care for ALHIV.

Where Are the Newly Diagnosed HIV Positives in Kenya? Time to Consider Geo-Spatially Guided Targeting at a Finer Scale to Reach the "First 90"

Background: The UNAIDS 90-90-90 Fast-Track targets provide a framework for assessing coverage of HIV testing services (HTS) and awareness of HIV status - the "first 90." In Kenya, the bulk of HIV testing targets are aligned to the five highest HIV-burden counties. However, we do not know if most of the new HIV diagnoses are in these five highest-burden counties or elsewhere. Methods: We analyzed facility-level HTS data in Kenya from 1 October 2015 to 30 September 2016 to assess the spatial distribution of newly diagnosed HIV-positives. We used the Moran's Index (Moran's I) to assess global and local spatial auto-correlation of newly diagnosed HIV-positive tests and Kulldorff spatial scan statistics to detect hotspots of newly diagnosed HIV-positive tests. For aggregated data, we used Kruskal-Wallis equality-of-populations non-parametric rank test to compare absolute numbers across classes. Results: Out of 4,021 HTS sites, 3,969 (98.7%) had geocodes available. Most facilities (3,034, 76.4%), were not spatially autocorrelated for the number of newly diagnosed HIV-positives. For the rest, clustering occurred as follows; 438 (11.0%) were HH, 66 (1.7%) HL, 275 (6.9%) LH, and 156 (3.9%) LL. Of the HH sites, 301 (68.7%) were in high HIV-burden counties. Over half of 123 clusters with a significantly high number of newly diagnosed HIV-infected persons, 73(59.3%) were not in the five highest HIV-burden counties. Clusters with a high number of newly diagnosed persons had twice the number of positives per 1,000,000 tests than clusters with lower numbers (29,856 vs. 14,172). Conclusions: Although high HIV-burden counties contain clusters of sites with a high number of newly diagnosed HIV-infected persons, we detected many such clusters in low-burden counties as well. To expand HTS where most needed and reach the "first 90" targets, geospatial analyses and mapping make it easier to identify and describe localized epidemic patterns in a spatially dispersed epidemic like Kenya's, and consequently, reorient and prioritize HTS strategies.

Higher contraceptive uptake in HIV treatment centers offering integrated family planning services: A national survey in Kenya

OBJECTIVES

Integrating family planning (FP) into routine HIV care and treatment are recommended by WHO guidelines to improve FP access among HIV-infected individuals in sub-Saharan Africa. This study sought to assess factors that influence the delivery of integrated FP services and the impact of facility-level integration of FP on contraceptive uptake among women living with HIV (WLWH).

STUDY DESIGN

A national cross-sectional study was conducted among WLWH at HIV Care and Treatment centers with >1000 antiretroviral treatment (ART) clients per year. A mobile team visited 108 HIV Care and Treatment centers and administered surveys to key informants regarding facility attributes and WLWH regarding FP at these centers between June and September 2016. We classified facilities offering FP services within the same facility as 'integrated' facilities.

RESULTS

4805 WLWH were enrolled at 108 facilities throughout Kenya. The majority (73%) of facilities offered integrated FP services. They were more likely to be offered in public than private facilities (Prevalence Ratio [PR]: 1.86, 95% Confidence Interval [CI]: 1.11-3.11; p = 0.02] and were more common in the Nyanza region than the Nairobi region (77% vs 35% respectively, p = 0.06). Any contraceptive use (89% vs 80%), use of modern contraception (88% vs 80%), dual method use (40% vs 30%), long-acting reversible contraception (LARC) (28% vs 20%), and non-barrier short-term methods (34% vs 27%) were all significantly higher in facilities with integrated FP services (p < 0.001).

CONCLUSIONS

The majority of high volume facilities integrated FP services into HIV care. Integrating FP services may increase modern contraceptive use among WLWH.

IMPLICATIONS

Integration of FP services was associated with higher modern contraceptive use, lower unmet need for modern methods and higher use of long-acting, reversible contraception (LARC), and non-barrier short-term methods among women living with HIV. Despite high prevalence of integration of FP services, organizational challenges remain at integrated clinics.

Male partner antenatal clinic attendance is associated with increased uptake of maternal health services and infant BCG immunization: a national survey in Kenya

BACKGROUND

Male partner antenatal clinic (ANC) attendance may improve maternal uptake of maternal child health (MCH) services.

METHODS

We conducted a cross-sectional survey of mother-infant pairs attending week-6 or month-9 infant immunizations at 120 high-volume MCH clinics throughout Kenya. Clinics were selected using probability proportionate to size sampling. Women were interviewed using structured questionnaires and clinical data was verified using MCH booklets. Among married women, survey-weighted logistic regression models accounting for clinic-level clustering were used to compare outcomes by male ANC attendance and to identify its correlates.

RESULTS

Among 2521 women attending MCH clinics and had information on male partner ANC attendance, 2141 (90%) were married of whom 806 (35%) had male partners that attended ANC. Among married women, male partner ANC attendance was more frequent among women with higher education, women who requested their partners to attend ANC, had male partners with higher education, did not report partner violence, and had disclosed their HIV status (p < 0·001 for each). Additionally, male ANC attendance was associated with higher uptake of ANC visits [adjusted Odds Ratio (AOR) = 1·67, 95% confidence interval (CI) 1·36-2·05,], skilled delivery (AOR = 2·00, 95% CI 1·51-2·64), exclusive breastfeeding (AOR = 1·70, 95% CI 1·00-2·91), infant Bacille Calmette Guerin (BCG) immunization (AOR = 3·59, 95% CI 1·00-12·88), and among HIV-infected women, antiretroviral drugs (aOR = 6·16, 95% CI 1·26-30·41).

CONCLUSION

Involving male partners in MCH activities amplifies benefits of MCH services by engaging partner support for maternal uptake of services.

Prevalence and correlates of non-disclosure of maternal HIV status to male partners: a national survey in Kenya

BACKGROUND

Prevention of mother-to-child HIV transmission (PMTCT) programs usually test pregnant women for HIV without involving their partners. Non-disclosure of maternal HIV status to male partners may deter utilization of PMTCT interventions since partners play a pivotal role in decision-making within the home including access to and utilization of health services.

METHODS

Mothers attending routine 6-week and 9-month infant immunizations were enrolled at 141 maternal and child health (MCH) clinics across Kenya from June-December 2013. The current analysis was restricted to mothers with known HIV status who had a current partner. Multivariate logistic regression models adjusted for marital status, relationship length and partner attendance at antenatal care (ANC) were used to determine correlates of HIV non-disclosure among HIV-uninfected and HIV-infected mothers, separately, and to evaluate the relationship of non-disclosure with uptake of PMTCT interventions. All analyses accounted for facility-level clustering, RESULTS: Overall, 2522 mothers (86% of total study population) met inclusion criteria, 420 (17%) were HIV-infected. Non-disclosure of HIV results to partners was higher among HIV-infected than HIV-uninfected women (13% versus 3% respectively, p < 0.001). HIV-uninfected mothers were more likely to not disclose their HIV status to male partners if they were unmarried (adjusted odds ratio [aOR] = 3.79, 95% CI: 1.56-9.19, p = 0.004), had low (≤KSH 5000) income (aOR = 1.85, 95% CI: 1.00-3.14, p = 0.050), experienced intimate partner violence (aOR = 3.65, 95% CI: 1.84-7.21, p < 0.001) and if their partner did not attend ANC (aOR = 4.12, 95% CI: 1.89-8.95, p < 0.001). Among HIV-infected women, non-disclosure to male partners was less likely if women had salaried employment (aOR = 0.42, 95%CI: 0.18-0.96, p = 0.039) and each increasing year of relationship length was associated with decreased likelihood of non-disclosure (aOR = 0.90, 95% CI: 0.82-0.98, p = 0.015 for each year increase). HIV-infected women who did not disclose their HIV status to partners were less likely to uptake CD4 testing (aOR = 0.32, 95% CI: 0.15-0.69, p = 0.004), to use antiretrovirals (ARVs) during labor (OR = 0.38, 95% CI 0.15-0.97, p = 0.042), or give their infants ARVs (OR = 0.08, 95% CI 0.02-0.31, p < 0.001).

CONCLUSION

HIV-infected women were less likely to disclose their status to partners than HIV-uninfected women. Non-disclosure was associated with lower use of PMTCT services. Facilitating maternal disclosure to male partners may enhance PMTCT uptake.

Spatial-temporal trend for mother-to-child transmission of HIV up to infancy and during pre-Option B+ in western Kenya, 2007-13

Introduction

Using spatial–temporal analyses to understand coverage and trends in elimination of mother-to-child transmission of HIV (e-MTCT) efforts may be helpful in ensuring timely services are delivered to the right place. We present spatial–temporal analysis of seven years of HIV early infant diagnosis (EID) data collected from 12 districts in western Kenya from January 2007 to November 2013, during pre-Option B+ use.

Methods

We included in the analysis infants up to one year old. We performed trend analysis using extended Cochran–Mantel–Haenszel stratified test and logistic regression models to examine trends and associations of infant HIV status at first diagnosis with: early diagnosis (<8 weeks after birth), age at specimen collection, infant ever having breastfed, use of single dose nevirapine, and maternal antiretroviral therapy status. We examined these covariates and fitted spatial and spatial–temporal semiparametric Poisson regression models to explain HIV-infection rates using R-integrated nested Laplace approximation package. We calculated new infections per 100,000 live births and used Quantum GIS to map fitted MTCT estimates for each district in Nyanza region.

Results

Median age was two months, interquartile range 1.5–5.8 months. Unadjusted pooled positive rate was 11.8% in the seven-years period and declined from 19.7% in 2007 to 7.0% in 2013, p < 0.01. Uptake of testing ≤8 weeks after birth was under 50% in 2007 and increased to 64.1% by 2013, p < 0.01. By 2013, the overall standardized MTCT rate was 447 infections per 100,000 live births. Based on Bayesian deviance information criterion comparisons, the spatial–temporal model with maternal and infant covariates was best in explaining geographical variation in MTCT.

Discussion

Improved EID uptake and reduced MTCT rates are indicators of progress towards e-MTCT. Cojoined analysis of time and covariates in a spatial context provides a robust approach for explaining differences in programmatic impact over time.

Conclusion

During this pre-Option B+ period, the prevention of mother to child transmission program in this region has not achieved e-MTCT target of ≤50 infections per 100,000 live births. Geographical disparities in program achievements may signify gaps in spatial distribution of e-MTCT efforts and could indicate areas needing further resources and interventions.

Antiretroviral treatment scale-up among persons living with HIV in Kenya: results from a nationally representative survey

BACKGROUND

In 2007, 29% of HIV-infected Kenyans in need of antiretroviral therapy (ART), based on an immunologic criterion of CD4 ≤350 cells per microliter, were receiving ART. Since then, substantial treatment scale-up has occurred in the country. We analyzed data from the second Kenya AIDS Indicator Survey (KAIS 2012) to assess progress of treatment scale-up in Kenya.

METHODS

KAIS 2012 was a nationally representative survey of persons aged 18 months to 64 years that collected information on HIV status, care, and treatment. ART eligibility was defined based on 2 standards: (1) 2011 Kenya eligibility criteria for ART initiation: CD4 ≤350 cells per microliter or co-infection with active tuberculosis and (2) 2013 World Health Organization (WHO) eligibility criteria for ART initiation: CD4 ≤500 cells per microliter, co-infection with active tuberculosis, currently pregnant or breastfeeding, and infected partners in serodiscordant relationships. Blood specimens were tested for HIV antibodies and HIV-positive specimens tested for CD4 cell counts.

RESULTS

Among 13,720 adults and adolescents aged 15-64 years, 11,626 provided a blood sample, and 648 were HIV infected. Overall, 58.8% [95% confidence interval (CI): 52.0 to 65.5) were eligible for treatment using the 2011 Kenya eligibility criteria and 77.4% (95% CI: 72.4 to 82.4) using the 2013 WHO eligibility criteria. Coverage of ART was 60.5% (95% CI: 50.8 to 70.2) using the 2011 Kenya eligibility criteria and 45.9% (95% CI: 37.7 to 54.2) using the 2013 WHO eligibility criteria.

CONCLUSIONS

ART coverage has increased from 29% in 2007 to 61% in 2012. If Kenya adopts the 2013 WHO guidelines for ART initiation, need for ART increases by an additional 19 percentage points and current coverage decreases by an additional 15 percentage points, representing an additional 214,000 persons who will need to be reached.

Prevalence of symptoms of asthma, rhinitis and eczema in 13- to 14-year-old children in Africa: the International Study of Asthma and Allergies in Childhood Phase III

Phase I of the International Study of Asthma and Allergies in Childhood has provided valuable information regarding international prevalence patterns and potential risk factors in the development of asthma, allergic rhinoconjunctivitis and eczema. However, in Phase I, only six African countries were involved (Algeria, Tunisia, Morocco, Kenya, South Africa and Ethiopia). Phase III, conducted 5-6 years later, enrolled 22 centres in 16 countries including the majority of the centres involved in Phase I and new centres in Morocco, Tunisia, Democratic Republic of Congo, Togo, Sudan, Cameroon, Gabon, Reunion Island and South Africa. There were considerable variations between the various centres of Africa in the prevalence of the main symptoms of the three conditions: wheeze (4.0-21.5%), allergic rhinoconjunctivitis (7.2-27.3%) and eczema (4.7-23.0%). There was a large variation both between countries and between centres in the same country. Several centres, including Cape Town (20.3%), Polokwane (18.0%), Reunion Island (21.5%), Brazzaville (19.9%), Nairobi (18.0%), Urban Ivory Coast (19.3%) and Conakry (18.6%) showed relatively high asthma symptom prevalences, similar to those in western Europe. There were also a number of centres showing high symptom prevalences for allergic rhinoconjunctivitis (Cape Town, Reunion Island, Brazzaville, Eldoret, Urban Ivory Coast, Conakry, Casablanca, Wilays of Algiers, Sousse and Eldoret) and eczema (Brazzaville, Eldoret, Addis Ababa, Urban Ivory Coast, Conakry, Marrakech and Casablanca).

Estimating and projecting HIV prevalence and AIDS deaths in Tanzania using antenatal surveillance data

Background

The Estimations and Projections Package (EPP 2005) for HIV/AIDS estimates and projects HIV prevalence, number of people living with HIV and new HIV infections and AIDS cases using antenatal clinic (ANC) surveillance data. The prevalence projection produced by EPP can be transferred to SPECTRUM, a demographic projectionmodel, to calculate the number of AIDS deaths. This paper presents estimates and projections of HIV prevalence, new cases of HIV infections and AIDS deaths in Tanzania between 2001 and 2010 using the EPP 2005 and SPECTRUM soft-wares on ANC data.

Methods

For this study we used; the 1985 – 2004 ANC data set, the 2005 UN population estimates for urban and rural adults, which is based on the 2002 population census, and results of the 2003 Tanzania HIV Indicator Survey. The ANC surveillance sites were categorized into urban and rural areas on the basis of the standard national definitions of urban and rural areas, which led to 40 urban and 35 rural clinic sites. The rural and urban epidemics were run independently by fitting the model to all data and on level fits.

Results

The national HIV prevalence increased from 0% in 1981 to a peak of 8.1% in 1995, and gradually decreased to 6.5% in 2004 which stabilized until 2010. The urban HIV epidemic increased from 0% in 1981 peaking at 12.6% in 1992 and leveled to between 10.9% and 11.8% from 2003 to 2010. The rural epidemic peaked in 1995 at 7.0% and gradually declined to 5.2% in 2004, and then stabilized at between 5.1% and 5.3% from 2005 to 2010. New infections are projected to rise steadily, resulting in 250,000 new cases in 2010. Deaths due to AIDS started in 1985 and rose steadily to reach 120,000 deaths in 2010, with more females dying than men.

Conclusion

The fact that the number of new infections is projected to increase steadily to reach 250,000 per year in 2010 calls for more concerted efforts to combat the spread of HIV infection particularly in the rural areas where the infrastructure needed for prevention programmes such as counseling and testing, condom accessibility and AIDS information is less developed.

Surveillance of HIV and syphilis infections among antenatal clinic attendees in Tanzania-2003/2004

BACKGROUND

This paper presents the prevalence of human immunodeficiency virus (HIV) and syphilis infections among women attending antenatal clinics (ANC) in Tanzania obtained during the 2003/2004 ANC surveillance.

METHODS

Ten geographical regions; six of them were involved in a previous survey, while the remaining four were freshly selected on the basis of having the largest population among the remaining 20 regions. For each region, six ANC were selected, two from each of three strata (urban, peri-urban and rural). Three of the sites did not participate, resulting into 57 surveyed clinics. 17,813 women who were attending the chosen clinics for the first time for any pregnancy between October 2003 and January 2004. Patient particulars were obtained by interview and blood specimens were drawn for HIV and syphilis testing. HIV testing was done anonymously and the results were unlinked.

RESULTS

Of the 17,813 women screened for HIV, 1,545 (8.7% (95% CI = 8.3-9.1)) tested positive with the highest prevalence in women aged 25-34 years (11%), being higher among single women (9.7%) than married women (8.6%) (p < 0.07), and increased with level of education from 5.2% among women with no education to 9.3% among those at least primary education (p < 0.001). Prevalence ranged from 4.8% (95% CI = 3.8%-9.8%) in Kagera to 15.3% (95% CI = 13.9%-16.8%) in Mbeya and was; 3.7%, 4.7%, 9.1%, 11.2% and 15.3% for rural, semi-urban, road side, urban and 15.3% border clinics, respectively (p < 0.001). Of the 17,323 women screened for syphilis, 1265 (7.3% (95%CI = 6.9-7.7)) were positive, with highest prevalence in the age group 35-49 yrs (10.4%) (p < 0.001), and being higher among women with no education than those with some education (9.8% versus 6.8%) (p < 0.0001), but marital status had no influence. Prevalence ranged from 2.1% (95% CI = 1.4%-3.0%) in Kigoma to 14.9% (95% CI = 13.3%-16.6%) in Kagera and was 16.0% (95% CI = 13.3-18.9), 10.5% (95% CI = 9.5-11.5) and 5.8% (95% CI = 5.4-6.3) for roadside, rural and urban clinics, respectively. Syphilis and HIV co-infection was seen in 130/17813 (0.7%).

CONCLUSION

The high HIV prevalence observed among the ANC clinic attendees in Tanzania call for expansion of current voluntary counselling and testing (VCT) services and access to antiretroviral drugs (ARV) in the clinics. There is also a need for modification of obstetric practices and infant feeding options in HIV infection in order to prevent mother to child transmission of HIV. To increase uptake to HIV testing the opt-out strategy in which all clients are offered HIV testing is recommended in order to meet the needs of as many pregnant women as possible.

Cost-effectiveness of polymerase chain reaction versus Ziehl-Neelsen smear microscopy for diagnosis of tuberculosis in Kenya

BACKGROUND

Laboratory services, particularly in large sub-Saharan cities, are overstretched, and it is becoming difficult both for patients and health staff to adhere to the diagnostic procedures for tuberculosis. Alternative techniques would be welcome. The polymerase chain reaction (PCR) has the potential to be cost-effective. We compared the cost-effectiveness of two diagnostic strategies, Ziehl-Neelsen (ZN) on three specimens followed by chest X-ray (CXR), and AMPLICOR MTB PCR on the first specimen only.

METHODS

Three sputum samples were collected from tuberculosis (TB) suspects attending the Rhodes Chest Clinic, Nairobi. All samples were subjected to ZN, PCR and Löwenstein-Jensen culture used as gold standard. CXR was used to diagnose smear-negative TB. Cost analysis included health service and patient costs.

RESULTS

Costs per correctly diagnosed case were US dollar 41 and dollar 67 for ZN and PCR, respectively. When treatment costs were included, including treatment of culture-negative cases, PCR was more cost-effective: dollar 382 vs. dollar 412.

CONCLUSION

PCR may be an alternative in settings with many patients. PCR is patient friendly, CXR is not necessary and, unlike ZN, its performance is hardly affected by the human immunodeficiency virus. PCR can handle large numbers of specimens, with results becoming available on the same day.

Quality of glycaemic control in ambulatory diabetics at the out-patient clinic of Kenyatta National Hospital, Nairobi

BACKGROUND

Treatment of diabetes mellitus is based on the evidence that lowering blood glucose as close to normal range as possible is a primary strategy for reducing or preventing complications or early mortality from diabetes. This suggests poorer glycaemic control would be associated with excess of diabetes-related morbidity and mortality. This presumption is suspected to reach high proportions in developing countries where endemic poverty abets poor glycaemic control. There is no study published on Kenyan patients with diabetes mellitus about their glycaemic control as an audit of diabetes care.

OBJECTIVE

To determine the glycaemic control of ambulatory diabetic patients.

DESIGN

Cross-sectional study on each clinic day of a randomly selected sample of both type 1 and 2 diabetic patients.

SETTING

Kenyatta National Hospital.

METHODS

Over a period of six months, January 1998 to June 1998. During routine diabetes care in the clinic, mid morning random blood sugar and glycated haemoglobin (HbA1c) were obtained.

RESULTS

A total of 305 diabetic patients were included, 52.8% were females and 47.2% were males. 58.3% were on Oral Hypoglycaemic Agent (OHA) only, 22.3% on insulin only; 9.2% on OHA and insulin and 4.6% on diet only. 39.5% had mean HbA1c < or = 8% while 60.5% had HbA1c > or = 8%. Patients on diet-only therapy had the best mean HbA1c = 7.04% while patients on OHA-only had the worst mean HbA1c = 9.06%. This difference was significant (p=0.01). The former group, likely, had better endogenous insulin production. The influence of age, gender and duration of diabetes on the level of glycaemic control observed did not attain statistically significant proportions.

CONCLUSION

The majority of ambulatory diabetic patients attending the out-patient diabetic clinic had poor glycaemic control. The group with the poorest level of glycaemic control were on OHA-only, while best control was observed amongst patients on diet-only, because of possible fair endogenous insulin production. Poor glycaemic control was presumed to be due to sub-optimal medication and deteriorating diabetes. There is need to empower patients with knowledge and resources to enhance their individual participation in diabetes self-care. Diabetes care providers and facilities also need capacity building to improve care of patients with diabetes.

Pneumocystis carinii pneumonia in HIV/AIDS patients at an urban district hospital in Kenya

BACKGROUND

Pneumocystis carinii pneumonia has generally been regarded to be an uncommon opportunistic infection in HIV infected individuals in sub-Saharan Africa. The reason for this has not been clear but postulates included a lack of suitable pathogenic types in the African environment, diagnostic difficulties and the more commonly held belief that African HIV infected individuals were dying early from common non-opportunistic pathogens before severe degrees of immunosuppression occured. Recently a trend has emerged at the Mbagathi district hospital whereby an increasing number of HIV infected patients are empirically treated for Pneumocystis carinii pneumonia (PCP) based on clinical and radiological features.

OBJECTIVE

To determine the prevalence of PCP and clinical outcomes of HIV infected patients presenting at the Mbagathi District Hospital, Nairobi with the presumptive diagnosis of PCP.

SETTING

Mbagathi District Hospital, a 169-bed public hospital in Nairobi, Kenya.

METHODS

Patients presenting with a sub-acute onset of cough and dyspnoea were eligible for the study if they were found to have bilateral pulmonary shadows and had negative sputum smears for AFBS. Consenting patients who had no contraindication to fiberoptic bronchoscopy had a clinical evaluation which was followed with a fiberoptic bronchoscopy procedure where bronchoalveolar lavage fluid (BALF) was obtained. BALF was examined for cysts of P. carinii using toluidine blue stain and immunofluorescent antibody test (IFAT). BALF was also processed for fungi, bacteria and mycobacteria using routine procedures. Standard treatment with high dose cotrimoxazole was offered to all patients who were then followed up until discharge from hospital or death whichever came first.

RESULTS

Between June 1999 and August 2000 a total of 63 patients were referred for bronchoscopy. Of these four declined to undergo the fiberoptic bronchoscopy procedure, four died before the procedure could be done, one was judged too sick to undergo the procedure and three had been on cotrimoxazole for longer than five days. Thus 51 patients underwent bronchoscopy. Pneumocystis carinii stain was positive in 19 (37.2%) while death occured in 16 (31.4%) of the 51 patients. There were more deaths in those without PCP but this difference was not statistically significant (odds ratio 0.68 (95% CI 0.35-1.32; P=0.2).

CONCLUSION

PCP was found to be common in HIV infected patients presenting with clinical and radiological features of the disease. The mortality rate for patients with a presumptive diagnosis of PCP is high. This study suggests that cotrimoxazole preventive therapy may be a useful intervention in symptomatic HIV infected patients in Kenya for the prevention of PCP and may avert deaths from this disease.

Validity of random blood glucose as a predictor of the quality of glycaemic control by glycated haemoglobin in out-patient diabetic patients at Kenyatta National Hospital

BACKGROUND

Patients with diabetes mellitus in Kenya come to the hospital for follow-up visits very infrequently. For most of these patients their blood glucose monitoring is done only on the day of visit to the doctor.

OBJECTIVE

To determine how well the physician-based morning random blood level determines or reflects the quality of glycaemic control.

DESIGN

Cross-sectional study (morning, random blood glucose taken between 8.00 a.m. and 12.00 noon).

SETTING

Out-patient diabetic clinic of Kenyatta National Hospital.

SUBJECTS

Patients with diabetes mellitus either type 1 or type 2 attending the out-patient clinic.

MAIN OUTCOME MEASURES

Random blood glucose (morning) and glycated haemoglobin (HbA1c).

RESULTS

The morning random glucose level had a linear relationship with glycated haemoglobin levels taken simultaneously. A blood glucose level of 7 mmol/l had 92.7% sensitivity for good control (HbA1c < or = 7.8%) on a blood sample which was taken simultaneously and 59.8% specific for the same. When blood glucose cut-off level was raised to 10 mmol/l sensitivity fell to 66.3% for HbA1c < or = 7.8%, and 83.2% specificity for poor glycaemic control (HbA1c > 7.8%). There was marked fall in sensitivity of rising random blood glucose level in predicting good glycaemic control in our study, with concomitant rise in specificity of those high cut-off levels of blood glucose in predicting poor glycaemic control.

CONCLUSION

Morning random blood glucose in the ambulatory diabetic patients related well to simultaneously assayed HbA1c. Blood glucose within usual therapeutic targets of 4-8 mmol/l predicted good glycaemic control (HbA1c < or = 7.8%) with high sensitivity at the range of 86.3-98.4%. In resource-poor settings, the morning random blood glucose assay, which is done in patients who may attend the diabetic clinic in the morning hours, may be used to predict the quality of their diabetic control. However caution should be exercised in its widespread use because its overall applicability may be clinic-specific depending largely on the average metabolic control of the diabetic population using that clinic. Further studies need to be done to relate HbA1c to blood glucose levels obtained at different times of the day in this population to determine the best predictor of good glycaemic control.

Tuberculosis re-treatment outcomes within the public service in Nairobi, Kenya

OBJECTIVES

This study was undertaken to describe treatment outcomes in patients started on a re-treatment drug regimen, assess the quality of follow up procedures and the adequacy of the currently advocated re-treatment drug regimen in Nairobi, Kenya.

DESIGN

A retrospective study.

SETTING

Mbagathi District Hospital (MDH), Nairobi, a public hospital that serves as the Tuberculosis (Tb) referral centre for Nairobi.

MATERIALS AND METHODS

The Tb register at the MDH was used to identify patients who were on the re-treatment regimen for Tb. Case records for these patients were then retrieved. From these sources, information on age, sex, HIV status, previous and current tuberculosis disease and drug regimens, adherence to treatment and treatment outcomes, was obtained. Descriptive statistics was used to analyse the data.

RESULTS

Of the total of 4702 patients registered at the MDH between 1996 and 1997, 593 (12.6%) were patients with either recurrent Tb, returning to treatment after default or had failed initial treatment. Of the 593 patients, case records were unavailable for 168 and 17 were children below the age of ten in whom the diagnosis of Tb was uncertain making a total of 185 patients who were excluded from the study. Of the remaining 408 patients, 77 (18.9%) were cured, 61 (15.0%) completed treatment without confirmation of cure, two (0.5%) defaulted, six (1.5%) died and 262 (64.2%) had no outcome information. There were no treatment failures. Treatment success defined as cure or treatment completion was achieved in 94.5% of the 146 patients in whom outcome data were available. HIV positive patients had a statistically significant poorer success rate (34/40, 85%) when compared with HIV negative patients (104/106, 94%), p=0.004. Mycobacterium tuberculosis culture and drug susceptibility testing, was not done.

CONCLUSION

The high number of patients with no treatment outcome information at the MDH is worrying, as these patients may harbour drug resistant bacilli and reflects an inadequate follow up service for Tb re-treatment in Nairobi. However, where treatment outcomes could be assessed, the currently advocated re-treatment regimen achieved a high success rate. These observations point to an urgent need to improve Tb documentation and follow up procedures within the public service in Nairobi in order to forestall the emergence and spread of drug resistant Tb.

Tuberculosis and the HIV epidemic: increasing annual risk of tuberculous infection in Kenya, 1986-1996

OBJECTIVES

The purpose of this study was to assess the impact of the increased incidence of tuberculosis (TB) due to HIV infection on the risk of TB infection in schoolchildren.

METHODS

Tuberculin surveys were carried out in randomly selected primary schools in 12 districts in Kenya during 1986 through 1990 and 1994 through 1996. Districts were grouped according to the year in which TB notification rates started to increase. HIV prevalence in TB patients and changes in TB infection prevalence were compared between districts.

RESULTS

Tuberculous infection prevalence rates increased strongly in districts where TB notification rates had increased before 1994 (odds ratio = 3.1, 95% confidence interval = 2.3, 4.1) but did not increase in districts where notification rates had increased more recently or not at all. HIV prevalence rates in TB patients were 50% in districts with an early increase in notification rates and 28% in the other study districts.

CONCLUSIONS

Countries with an increasing prevalence of HIV infection will need additional resources for TB control, not only for current patients but also for the patients in additional cases arising from the increased risk of TB infection.

Home environment and asthma in Kenyan schoolchildren: a case-control study

BACKGROUND

There is increasing evidence that environmental factors contribute to the development of asthma, so the relationship was studied between home environment factors and asthma among school children of varying socioeconomic backgrounds living in a developing country.

METHODS

A case-control study was performed in participants of a prevalence survey which included 77 schoolchildren with asthma (defined by a history of wheeze, doctor diagnosis, or a decline in FEV1 of > or = 10% at five or 10 minutes after exercise) and 77 age and gender matched controls. Subjects were selected from 402 school children aged 9-11 years attending five primary schools in the city of Nairobi who participated in a prevalence survey of asthma. Visits were made to the homes of cases and controls and visual inspection of the home environment was made using a checklist. A questionnaire regarding supplemental salt intake, parental occupation, cooking fuels, and health of all children in the family was administered by an interviewer.

RESULTS

In multivariate analysis the following factors were associated with asthma: damage caused by dampness in the child's sleeping area (adjusted odds ratio (OR) 4.9; 95% confidence interval (CI) 2.0 to 11.7), air pollution in the home (OR 2.5; 95% CI 2.0 to 6.4), presence of rugs or carpets in child's bedroom (OR 3.6; 95% CI 1.5 to 8.5). Children with asthma reported a supplemental mean daily salt intake of 817 mg compared with 483 mg in controls.

CONCLUSIONS

Home environmental factors appear to be strongly associated with asthma in schoolchildren in a developing nation. These findings suggest a number of hypotheses for further studies.
