BackgroundCardiorenal anemia syndrome (CRAS) is an evolving global epidemic associated with increased morbimortality and cost of care. The management of patients with CRAS remains a challenging undertaking worldwide and the lack of evidence-based clinical guidelines adds to the challenge. We aimed to explore the prevalence and survival rates of heart failure patients with CRAS in Tanzania.MethodsWe screened 789 patients and consecutively recruited 463 who met the inclusion criteria. Each participant underwent an interview, physical examination, anthropometric measurements, anemia, renal functions and echocardiographic assessment. All participants were followed until death or for up-to 180 days, whichever came first. Bivariate comparison and subsequent Cox proportional-hazards regression model were used to compare the CRAS and non-CRAS groups with respect to the primary end point.ResultsThe mean age of participants was 46.4 ± 18.9 years, and 56.5% were women. Overall, 51.9% of participants had renal insufficiency, 72.8% were anemic and 44.4% had CRAS. During a mean follow-up of 103 ± 75 days, 57.8% of participants died. Patients with CRAS displayed a higher mortality rate (73.5%) compared to those free of CRAS (45.8%), (p < 0.001). During multivariate analysis in a cox regression model of 21 potential predictors of mortality; renal dysfunction (HR 1.9; 95% CI 1.0–3.5; p = 0.03), severe anemia (HR 1.8; 95% CI 1.0–3.1; p = 0.04), hyponatremia (HR 2.2; 95% CI 1.3–3.7; p = 0.004) and rehospitalization (HR 4.3; 95% CI 2.2–8.4; p < 0.001) proved to be the strongest factors.ConclusionCardiorenal anemia syndrome is considerably prevalent and is associated with an increase in mortality amongst patients with heart failure. In view of this, timely, aggressive and collaborative measures to improve renal functions and/or correct anemia are crucial in the management of CRAS patients. Furthermore, these findings call for guideline committees to revise and/or develop evidence-based recommendations for management of patients with CRAS.Electronic supplementary materialThe online version of this article (doi:10.1186/s12872-017-0497-2) contains supplementary material, which is available to authorized users.

BackgroundGlobally, erectile dysfunction burden (ED) is rising appreciably and it is projected to affect about 332 million men by the year 2025. This rise is attributable to the rising incidence of conditions associated with ED including obesity, diabetes, hypertension, coronary artery disease and depression. We conducted this community-based screening to elucidate on the prevalence of ED and its associated factors among men residing in an urban community in Tanzania.MethodsWe conducted a cross-sectional community-based study and interviewed 441 men aged at least 18 years. Diabetes and hypertension were defined as per the International Diabetes Federation (IDF) and the 7th Report of the Joint National Committee (JNC 7) respectively. The 5-item version of the International Index of Erectile Function (IIEF-5) Scale was used to assess for erectile dysfunction. Multivariate logistic regression analyses were performed to explore the factors associated with ED.ResultsThe mean age was 47.1 years, 57.6 % had excess body weight, 8.2 % had diabetes and 61.5 % had high blood pressure. Overall, 24 % (106/441) of men in this study had some form of ED. Participants with age ≥55, positive smoking history, obesity, diabetes and hypertension displayed highest rates of ED in their respective subgroups. However, age ≥40 and diabetes were ultimately the strongest factors for ED after multivariate logistic regression analyses, (OR 5.0, 95 % CI 2.2–11.2, p < 0.001 and OR 5.3, 95 % CI 2.2–12.7, p < 0.001 respectively).ConclusionErectile dysfunction affects about a quarter of adult men living in Kinondoni district. Old age, obesity, smoking, hypertension and diabetes have the potential to increase the odds of ED up-to 5 times. In view of this, men with diabetes and hypertension should be offered screening services and treatment of ED as an integral component in their management.

BackgroundTakayasu arteritis is a granulomatous panarteritis that predominantly affects the aorta and its major branches. The initial manifestations of this large-vessel vasculitis are usually nonspecific; however, as the disease progresses, typical symptoms of arterial occlusion, aneurysmal formation, and vascular pain become evident. Ischemic ocular complications of Takayasu arteritis which could lead to complete loss of vision are not uncommon and depend on the obliterated portion(s) of carotid(s), the intensity and rate of progression of ocular vascular insufficiency, and sufficiency of the collateral blood supply to the eye.Case presentationA 24-year-old woman of African descent with prior normal vision was referred to us with a 3-year history of gradual decline in visual acuity in both eyes and unintentional weight loss (17 kg) within the past 1 year. A physical examination revealed feeble brachial and radial arterial pulses on her left side. She had sinus tachycardia (136 beats/minute) and her blood pressure was 85/59 mmHg on her left and 134/82 mmHg on her right side. Bilateral microaneurysms, dot and blot hemorrhages, and multiple ischemic areas of retina together with neovascularization in her right eye were noted during a funduscopic examination. Computed tomography angiography of her thoracic and abdominal aorta revealed irregular narrowing with variable degrees of stenosis, tapering, and corrugated appearance.ConclusionsDespite its rarity, Takayasu arteritis significantly impairs a patient’s quality of life and has a life-threatening potential. Early initiation of appropriate therapy could delay disease progression and reduce the associated complications.

BackgroundGlobally, over 36 million people were infected with human immunodeficiency virus by the end of 2015. The Sub-Saharan African region home to less than one-fifth of the global population disproportionately harbors over two-thirds of the total infections and related deaths. Residents of Sub-Saharan Africa continue to face limited access to allopathic medicine and it is estimated that over 80% of primary health care needs in the region are met through traditional healing practices. It is known that some of these practices are performed in groups and the use of unsterilized instruments is common thus potentiating the transmission of human immunodeficiency virus.Case presentationA 29-year-old business woman of African origin residing in rural Tanzania presented at a screening event to confirm her human immunodeficiency virus status. Her past medical history was unremarkable and so were two past pregnancies. As per the antenatal clinic card for the second pregnancy, her human immunodeficiency virus serostatus was negative. She reported that she had been taken to a traditional healer to take an oath of remaining faithful during her husband’s absence. The oath involved cutting of the healer’s skin followed by hers using the same instrument. Approximately 4 months following this traditional ritual she developed a febrile illness accompanied by enlarged lymph nodes of her neck. She was investigated for malaria, typhoid fever, and urinary tract infection which were negative but she tested positive for human immunodeficiency virus. Owing to her disbelief regarding the human immunodeficiency virus status, she went to three other care and treatment clinics and the results remained similar. She denied any history of transfusion or extramarital affairs. She tested positive at the screening event and enzyme-linked immunosorbent assay for human immunodeficiency virus performed at our institution was reactive. Tenofovir, lamivudine, and efavirenz antiretroviral combination was initiated.ConclusionsPersistence of cultural norms involving exposure of bodily fluids and use of unsterilized instruments especially in the developing world remains a viable source of human immunodeficiency virus transmission especially in rural areas.
