Prevalence and risk factors of cervical squamous intraepithelial lesions among HIV-infected women in Dar es Salaam, Tanzania.

ABSTRACT: To determine the prevalence and predictors of cervical squamous intraepithelial lesions (SIL) among HIV-infected women in Tanzania, a cross-sectional study was conducted among HIV-infected women at HIV care and treatment clinics. A Papanicolaou (Pap) smear was used as a screening tool for detection of cervical SIL. From December 2006 to August 2009, 1365 HIV-infected women received cervical screening. The median age was 35 (interquartile range [IQR]: 30-42) years, and the median CD4 + cell count was 164 (IQR: 80-257) cells/mm(3). The prevalence of cervical SIL was 8.7% (119/1365). In multivariate analysis, older age (≥50 versus 30-<40 years: prevalence ratio [PR], 2.36; 95% confidence interval [CI], 1.45-3.84, p for trend = 0.001), lower CD4 + cell counts (<100 versus ≥200 cells/mm(3): PR, 1.55; 95% CI, 1.01-2.36, p for trend = 0.03) and cervical inflammation (PR, 1.73; 95% CI, 1.16-2.60, p = 0.008) were associated with an increased risk of cervical SIL. Women with advanced WHO HIV disease stage (IV versus I/II: PR, 3.45; 95% CI, 1.35-8.85, p for trend = 0.01) had an increased risk for high-grade SIL. In resource-limited settings where it is not feasible to provide cervical cancer prevention services to all HIV-infected women, greater efforts should focus on scaling-up services among those who are older than 50 years, with lower CD4 cell counts and advanced HIV disease stage.

Project description:BackgroundMalaria is a major cause of paediatric morbidity and mortality. As no clinical features clearly differentiate malaria from other febrile illnesses, and malaria diagnosis is challenged by often lacking laboratory equipment and expertise, overdiagnosis and overtreatment is common.MethodsChildren admitted with fever at the general paediatric wards at Muhimbili National Hospital (MNH), Dar es Salaam, Tanzania from January to June 2009 were recruited consecutively and prospectively. Demographic and clinical features were registered. Routine thick blood smear microscopy at MNH was compared to results of subsequent thin blood smear microscopy, and rapid diagnostics tests (RDTs). Genus-specific PCR of Plasmodium mitochondrial DNA was performed on DNA extracted from whole blood and species-specific PCR was done on positive samples.ResultsAmong 304 included children, 62.6% had received anti-malarials during the last four weeks prior to admission and 65.1% during the hospital stay. Routine thick blood smears, research blood smears, PCR and RDT detected malaria in 13.2%, 6.6%, 25.0% and 13.5%, respectively. Positive routine microscopy was confirmed in only 43% (17/40), 45% (18/40) and 53% (21/40), by research microscopy, RDTs and PCR, respectively. Eighteen percent (56/304) had positive PCR but negative research microscopy. Reported low parasitaemia on routine microscopy was associated with negative research blood slide and PCR. RDT-positive cases were associated with signs of severe malaria. Palmar pallor, low haemoglobin and low platelet count were significantly associated with positive PCR, research microscopy and RDT.ConclusionsThe true morbidity attributable to malaria in the study population remains uncertain due to the discrepancies in results among the diagnostic methods. The current routine microscopy appears to result in overdiagnosis of malaria and, consequently, overuse of anti-malarials. Conversely, children with a false positive malaria diagnosis may die because they do not receive treatment for the true cause of their illness. RDTs appear to have the potential to improve routine diagnostics, but the clinical implication of the many RDT-negative, PCR-positive samples needs to be elucidated.

Project description:ObjectiveThis study assessed impaired fasting glucose and associated factors among perinatally HIV-infected adolescents and youths in Dar es salaam Tanzania.BackgroundImpaired fasting glucose is a marker of heightened risk for developing type 2 diabetes among perinatally HIV-infected individuals. Therefore, identifying individuals at this stage is crucial to enable early intervention. Therefore, we assessed impaired fasting glucose (IFG) and associated factors among perinatally HIV-infected population in Dar es salaam Tanzania.MethodsA cross-sectional study was conducted among 152 adolescents and youth attending HIV clinic at Muhimbili National Hospital and Infectious Disease Centre from July to August 2020. Fasting blood glucose (>8 hours) was measured using one-touch selects LifeScan, CA, USA. We also examined C-Reactive Protein and interleukin-6 inflammatory biomarkers in relation to impaired fasting glucose (IFG). Associations between categorical variables were explored using Chi-square, and poison regression with robust variance was used to calculate the prevalence ratios.ResultsOf the 152 participants, the majority were male (n=83[54.6%]), and the median age was 15(14-18) years. Overweight or obesity was prevalent in 16.4%, while more than one in ten (13.2%) had high blood pressure (≥149/90mmHg). All participants were on antiretroviral therapy (ART); 46% had used medication for over ten years, and about one in three had poor medication adherence. Among the recruited participants, 29% had impaired fasting glucose. The odds of IFG were two times higher in males compared to females (PR, 2.07, 95% CI 1.19 -3.59 p=0.001). Moreover, we found with every increase of Interleukin 6 biomarker there was a 1.01 probability increase of impaired fasting glucose (PR, 1.01, 95% CI 1.00 - 1.02 p=0.003).ConclusionAbout one in three perinatally HIV-infected youths had impaired fasting glucose in Dar es Salaam, Tanzania, with males bearing the biggest brunt. Moreover, with every increase of 1.101 of the probability of having IFG increased. This calls for urgent measures to interrupt the progression to diabetes disease and prevent the dual burden of disease for this uniquely challenged population.

Project description:BackgroundMore than three-fourths of cervical cancer cases occur in low- and middle-income countries, with sub-Saharan Africa (SSA) accounting for approximately 25% of global mortality. The significant rise in the prevalence of cervical cancer in SSA amplifies the burden on caregivers, contributing to elevated rates of mental illness, particularly among spouses who provide care. Men who assume the role of caregivers for their partners with cervical cancer encounter unique challenges and substantial adjustments across multiple facets of life, impacting both their own quality of life and that of their partners. Despite this, there is a notable lack of extensive research on the experiences of male partners in caregiving roles, particularly within SSA countries like Tanzania. Therefore, this study aimed to explore the experiences of male partners providing care for women with cervical cancer in Dar es Salaam, Tanzania.MethodsAn exploratory qualitative study was undertaken to explore the experiences of 13 male partners, selected purposively and guided by the principle of saturation. Data gathering employed in-depth interviews utilizing a semistructured interview guide, with subsequent analysis conducted via a thematic analysis approach.ResultsFive themes and 13 subthemes were generated, encompassing psychosocial distress, attitudes towards cervical cancer, unity in the provision of care, economic burden, and altered sexual relationships. Participants reported experiencing emotional distress, shifts in social responsibilities, financial challenges, and unfulfilled sexual needs. Moreover, they expressed the need for social, psychological, financial, and sexual and reproductive support.ConclusionThis study underscores the numerous challenges encountered by male partners caring for women with cervical cancer, encompassing emotional distress, financial strain, and shifts in social and sexual dynamics. The identified themes and subthemes highlight the intricate interplay of these difficulties and stress the necessity for holistic support systems addressing the social, psychological, financial, and sexual aspects of male partners' experiences. The findings emphasize the importance of designing and implementing comprehensive support programmes tailored to the diverse needs of male partners, ultimately enhancing their quality of life and overall well-being.Patient or public contributionBefore the study, the nursing manager assisted in selecting three male partners randomly. These partners were involved in the design of the participants' information sheet, the evaluation of the interview schedule and rooms, and the dissemination of information about the study's purpose to the target population. Their valuable input contributed to improving the participant information sheet, refining data collection procedures and addressing ethical considerations. However, these individuals were not considered study participants. Throughout the study, in-charge nurses in the hospital were informed about the study's goals and helped organize appointments with participants and manage the interview schedule.

Project description:BackgroundLong-term antiretroviral therapy has modified the clinical course of HIV infection to a chronic condition associated with increased risk of developing non-communicable diseases (NCDs). Information is scant, from sub-Saharan Africa, on the prevalence of NCDs and associated factors among individuals on ART.MethodologyWe consecutively enrolled individuals with HIV infection who were ART naïve and those on ART for ≥5 years (LTART) attending health facilities in Dar es Salaam. Participant's blood pressure, anthropometric measurements, and fasting blood glucose were recorded. Participants with impaired fasting blood glucose underwent an oral glucose tolerance test. A venous blood sample was sent to the lab for biochemical tests. Chi-square test was used to compare proportions, Poisson regression with robust standard errors was used to determine associations between variables.ResultsOverall, 612 individuals with HIV infection were enrolled, half of whom were ART naïve. Females comprised 71.9% and 68.0% of participants in the LTART and ART naïve study arms, respectively, p = 0.290. The mean age (±SD) was 44.9 ± 12.7 years and 37.5 ± 11.8 years among LTART and ART naïve participants, respectively, p<0.001. Hypertension was documented in 25.2% in those on LTART compared to 6.9% among ART naïve subjects, p<0.001. Impaired glucose tolerance was found in 22.9% and 4.6% among LTART compared to ART naïve subjects, p<0.001. Diabetes mellitus was detected in 17.0% of those on LTART compared to 3.9% ART naïve participants, p<0.001. Hypercholesterolemia was found in 30.4% of individuals on LTART compared to 16.7% of ART naïve subjects, p<0.001, and hypertriglyceridemia was found in 16.0% of participants on LTART compared to 9.5% of ART naïve, p = 0.015. LTART use, age ≥40 years, history of smoking, and body mass index were independently associated with NCDs.ConclusionHypertension, impaired glucose tolerance, diabetes mellitus, hypercholesterolemia, and hypertriglyceridemia were associated with long-term use of antiretroviral drugs.

Project description:BackgroundCervical cancer continues to be a major global public health concern affecting the lives of many women and resulting in financial burdens. In 2020, cervical cancer was the seventh most commonly diagnosed cancer among all cancers worldwide and Tanzania was ranked fourth among the countries with the highest incidence rates (59.1 new cases per 100,000 women) of cervical cancer. The lived experience and caring needs of patients and their families provide insights into the psychosocial aspects of healthcare among the affected population. However, there is inadequate information concerning the lived experiences of cervical cancer patients in Tanzania and Sub-Saharan Africa in general. This study aimed to explore the lived experiences and caring needs of cervical cancer patients at Ocean Road Cancer Institute (ORCI) in Dar es Salaam, Tanzania.MethodsA qualitative descriptive study was carried out among cervical cancer patients at ORCI in Dar es Salaam, Tanzania. Using a purposeful sampling technique, 12 cervical cancer patients were interviewed with the principles of saturation guiding sample size determination. A semi-structured face-to-face interview guide was employed to collect the information. A conventional content analysis approach was used to analyze data after translation with the aid of NVivo 12.0 computer software.ResultsFive themes emerged after data analysis: knowledge and attitude about cervical cancer, sufferings from a disease process, socio-economic disruptions, psychological problems, and sexual and reproductive concerns.ConclusionThe findings of this study provide insights into the life experiences and caring needs of cervical cancer patients and call for response from healthcare stakeholders to develop and implement comprehensive and culturally consonant approaches in providing care to the affected population. More qualitative studies are required to ascertain the lived experiences of advanced cervical cancer patients and those of long-term cervical cancer survivors.
