Nocturnal dipping of heart rate and blood pressure in people with HIV in Tanzania.

People with HIV (PWH) have a >2-fold greater risk for development of cardiovascular disease (CVD), which may be associated with abnormalities in 24-h ambulatory blood pressure measurement (ABPM) profile. We conducted a nested case-control study of ABPM in 137 PWH and HIV-uninfected controls with normal and high clinic blood pressure (BP) in Tanzania. Nocturnal non-dipping of heart rate (HR) was significantly more common among PWH than HIV-uninfected controls (p = .01). Nocturnal non-dipping of BP was significantly more common in PWH with normal clinic BP (p = .048). Clinical correlates of nocturnal non-dipping were similar in PWH and HIV-uninfected adults and included higher BMI, higher CD4+ cell count, and high C-reactive protein for HR and markers of renal disease for BP. In conclusion, nocturnal non-dipping of both BP and HR was more common in PWH but further research is needed to determine causes and consequences of this difference

A case of corrosive tracheoesophageal fistula: A complication of button battery ingestion

Key Clinical Message Button battery ingestion has been a common condition encountered by otorhinolaryngologists. Impaction in the esophagus can lead to serious and fatal complications such as tracheoesophageal fistula. Management involves a multidisciplinary team and varies from supportive therapy to surgical intervention. Abstract Ingestion of button batteries has been seen with increasing frequency over the past decade. In several small numbers of reported cases, their impaction in the esophagus has led to severe, sometimes fatal, complications. The management of these cases has varied from expectant, supportive therapy to early surgical intervention. We report a case of button battery ingestion that was diagnosed late and resulted in a complication of tracheoesophageal fistula with migration to the thorax which was managed by open surgery

Magnitude and correlates of virological failure among adult HIV patients receiving PI based second line ART regimens in north western Tanzania; a case control study

Abstract Background With a growing access to free ART, switching of ART to second line regimen has also become common following failure of first line ART regimens. Patients failing on first line ART regimens have been shown to stand a high risk of failing on subsequent second line ART regimens. The magnitude of those who are failing virologicaly on second line ART is not documented in our setting. This study was designed to assess the magnitude and correlates of second line ART treatment failure. Methods A retrospective analysis of patients on second line ART for at least 1 year was done at Bugando care and treatment center. Information on demographic, clinical and laboratory data were collected and analyzed using STATA 11. The proportion of patients with Virological failure was calculated and potential correlates of virological failure were determined by logistic regression model. Results In total 197 patients on second line ART were included in this study and 24 (12.18%) of them met criteria for virological failure. The odds of having virological failure on second line ART were independently associated with age of less than 30 years (AOR = 12.5, p = 0.001), being on first line for less than 3 years (AOR = 6.1, p = 0.002) and CD4 at switch to second line ART of less than 200cells/μl (AOR = 16.3, p < 0.001). Conclusion Virological failure among patients on second line ART is common. Predictors of virological failure in this study could assist in planning for strategies to improve the outcome of this subgroup of patients including close clinical follow up of patients at risk, a continued adherence intensification and a targeted resistance testing before switching to second line ART

Disseminated cryptococcosis in a HIV-negative patient: Case report of a newly diagnosed hypertensive adult presenting with hemiparesis

We report a case of disseminated cryptococcosis in a 42-year old immunocompetent female. Prior to admission at Bugando Medical Center, the patient was attended at three hospitals for hypertension and clinically diagnosed malaria. Following diagnosis of disseminated Cryptococcus at our center, she was successfully treated with fluconazole but remained with visual loss. Blood cultures should be considered in the management of any adult presenting with fever to enable early detection of the least expected differentials like in this case.
