ObjectiveTo determine and describe clinical symptoms, demographic characteristics and environmental exposures as determinants of pulmonary mycobacterial diseases among patients examined for tuberculosis in agropastoral communities in Northern Tanzania.MethodsThis was a cross sectional study. Sputum samples were collected from patients attending three hospitals in Tanzania, and were investigated for pulmonary tuberculosis by microscopy between November 2010 and June 2012. The patients were interviewed about background information, and potential exposure to mycobacteria.ResultsWe examined 1,711 presumptive tuberculosis cases where 936 (54.2%) were males and 775 (45.3%) females. Of all the study participants, 277 (16%) were found to have sputum samples positive for mycobacteria; 228 (13%) were smear positive, 123 (7%) were culture positive and 74 (4%) were positive by both smear microscopy and culture. Of the 123 mycobacterial culture positive, 15 (12.2%) had non-tuberculous mycobacteria. Males were more likely than females to be positive for mycobacteria. Factors associated with mycobacterial disease were loss of appetite, age groups below 41 years, and being a male. Among HIV negative patients, loss of appetite, age below 20 years and being a male were associated with being mycobacterial positive. Among HIV positive patients, males and those patients with a persistently coughing family member were more likely to harbor mycobacteria.ConclusionThe findings in this study show that both M. tuberculosis and non-tuberculous mycobacterial strains were prevalent in the study community. Some risk factors were identified. Although the reported predictors may improve screening for mycobacterial diseases, their use requires some precaution.

Objective: Taenia solium (T. solium) neurocysticercosis (NCC) affects the central nervous system and is associated with 30% of acquired epilepsy in some endemic areas. Epilepsy is a stigmatizing disease in many societies and people with epilepsy (PWE) and their families experience discrimination. This study aimed to explore the knowledge, perceptions, and experiences of epilepsy among PWE and their caregivers attending mental health clinics.Methods: In T. solium endemic areas of Tanzania, PWE and their caregivers attending mental health clinics were identified and their informed consent was sought prior to study participation. In-depth interviews were conducted in Swahili language and analyzed thematically. The coding was undertaken by two independent researchers using NVivo (Version 12, QSR International).Results: Thirty-eight participants were interviewed. Three themes were identified during the analysis, namely, knowledge about epilepsy; perception of epilepsy; and experience with epilepsy among PWE and their caregivers. Participants commonly defined epilepsy as a "falling disease," perceived to be caused by witchcraft, and were unaware of the association between T. solium and epilepsy.Stigmatization of epilepsy was reported as a problem. Reported treatment patterns after the initial onset of epilepsy varied widely; however, patients usually began treatment with traditional healing methods, and only later opted for biomedical treatment. Patients had generally poor adherence to antiseizure medication, which could be caused by inadequate knowledge or irregular supply.Significance: Level of knowledge about epilepsy was low, and NCC was not mentioned as a cause of epilepsy among participants. Epilepsy was generally perceived to be the result of witchcraft, evil spirits, or curses.

ObjectiveThe current study was conducted to assess experienced risk factors and perceptions of mycobacterial diseases in communities in northern Tanzania.MethodsWe conducted a cross-sectional study in Arusha and Manyara regions in Northern Tanzania. We enrolled tuberculosis (TB) patients attending Mount Meru Hospital, Enduleni Hospital and Haydom Lutheran Hospitals in Arusha municipality, Ngorongoro and Mbulu districts, respectively. Patient addresses were recorded during their first visit to the hospitals. Patients with confirmed diagnosis of TB by sputum smear microscopy and/or culture at central laboratory were followed up and interviewed using pre-tested questionnaires, and selected relatives and neighbors were also interviewed. The study was conducted between June 2011 and May 2013.ResultsThe study involved 164 respondents: 41(25%) were TB patients, 68(41.5%) were their relatives and 55(33.5%) their neighbors. Sixty four (39%) knew a risk factor for mycobacterial disease. Overall, 64(39%) perceived to be at risk of mycobacterial diseases. Exposure to potential risks of mycobacterial diseases were: keeping livestock, not boiling drinking water, large family, smoking and sharing dwelling with TB patients. Rural dwellers were more often livestock keepers (p<0.01), more often shared dwelling with livestock (p<0.01) than urban dwellers. More primary school leavers reported sharing dwelling with TB patients than participants with secondary and higher education (p = 0.01).ConclusionLivestock keeping, sharing dwelling with livestock, sharing household with a TB patient were perceived risk factors for mycobacterial diseases and the participants were exposed to some of these risk factors. Improving knowledge about the risk factors may protect them from these serious diseases.

In diabetes, persistent hyperglycemia results in increased production of free radicals especially oxygen free radicals, which can cause cell destruction and tissue injury resulting in cell dysfunction. With the premise that oxidative stress is a major cause of diabetic complications, we conducted a controlled laboratory based investigation on level of lipid peroxide levels in the serum of Type 1 and Type 2 diabetic patients attending Muhimbili National Hospital. From our clinical data it was observed that majority of the patients had higher waist to hip ration and body mass index, which suggests that the patients were either overweight or obese. The enrolled diabetic patients had higher lipid peroxide levels than controls and also Type 2 patients had higher lipid peroxide levels than Type 1 patients. Moreover, patients with known complications had higher lipid peroxide levels than patients without complications. The lipid peroxide levels in the diabetic patients were significantly different from that of the control subjects enrolled in the study. A majority of the diabetic patients had a poorly controlled blood sugar. Our finding hints that despite the fact that diabetic patients in our clinic are on follow up, they are at a risk of developing coronary heart diseases, neuropathy and other secondary diabetic complications.

Objective To determine the levels and patterns of resistance to first‐ and second‐line anti‐tuberculosis (TB) drugs among new and previously treated sputum smear positive pulmonary TB (PTB) patients. Methods We conducted a nationally representative cross‐sectional facility‐based survey in June 2017–July 2018 involving 45 clusters selected based on probability proportional to size. The survey aimed to determine the prevalence of anti‐TB drug resistance and associated risk factors among smear positive PTB patients in Tanzania. Sputum samples were examined using smear microscopy, Xpert MTB/RIF, culture and drug susceptibility testing (DST). Logistic regression was used to account for missing data and sampling design effects on the estimates and their standard errors. Results We enrolled 1557 TB patients, including 1408 (90.4%) newly diagnosed and 149 (9.6%) previously treated patients. The prevalence of multidrug‐resistant TB (MDR‐TB) was 0.85% [95% confidence interval (CI): 0.4–1.3] among new cases and 4.6% (95% CI: 1.1–8.2) among previously treated cases. The prevalence of Mycobacterium tuberculosis strains resistant to any of the four first‐line anti‐TB drugs (isoniazid, rifampicin, streptomycin and ethambutol) was 1.7% among new TB patients and 6.5% among those previously treated. Drug resistance to all first‐line drugs was similar (0.1%) in new and previously treated patients. None of the isolates displayed poly‐resistance or extensively drug‐resistant TB (XDR‐TB). The only risk factor for MDR‐TB was history of previous TB treatment (odds ratio = 5.7, 95% CI: 1.9–17.2). Conclusion The burden of MDR‐TB in the country was relatively low with no evidence of XDR‐TB. Given the overall small number of MDR‐TB cases in this survey, it will be beneficial focusing efforts on intensified case detection including universal DST.
