RESUMEN
PURPOSE: This study sought to delineate the clinical, laboratory, and imaging characteristics during multiple myeloma (MM) diagnosis, outline the treatment modalities administered, and ascertain the survival rates among patients with MM over a comprehensive 5-year span in Tanzania. METHODS: This retrospective cohort study investigated patients diagnosed with MM at the Cancer Care Clinic, Kilimanjaro Christian Medical Centre, between January 2017 and June 2022. Demographic data, clinical profiles, and survival outcomes were collected. The study employed the Kaplan-Meier method to determine overall survival (OS) and survival rates, supported by univariate analysis and a multivariate Cox regression model with significance of P < .05. RESULTS: In this study of 76 patients with MM, bone pain was the most common complaint (76.3%), and patients were age typically older than 50 years (82.5%). Laboratory tests showed frequent abnormalities, such as anemia (51.3%) and hypercalcemia (23.9%). Most patients were at stage III according to Durie Salmon Staging (82.7%), with imaging revealing various bone abnormalities. The median OS was 18.0 months, with 46.1% of patients passing away during the study period. Factors linked to shorter survival included anemia, renal failure, and bone involvement. Infection was the primary cause of death among these patients. The presenting complaint of bone pain significantly affected survival outcomes. CONCLUSION: This study provides a comprehensive understanding of MM within the Sub-Saharan African context, highlighting age-related disparities in diagnosis, predominant presenting symptoms like bone pain, factors contributing to delayed diagnoses, and the impact on survival rates. The findings underscore the critical need for early recognition, improved diagnostics, and tailored interventions to enhance outcomes for patients with MM in this region.

BACKGROUND: Africa has consistently had the highest prevalence (70.1%) of H. pylori, and this has led to significant cases of dyspepsia, gastric cancers, and upper gastrointestinal bleeding. However, most studies have used sero-prevalence, which might not give the current state of the infection. Among the tests, the stool antigen test is simple, quick, and effective. The study aimed to determine the feco-prevalence, endoscopic pattern, and associated factors of H. pylori infection among symptomatic adult patients in Northern Tanzania. MATERIALS AND METHODS: A hospital-based, cross-sectional study was conducted from October 2022 to April 2023 among adults attending the gastroenterology clinic at Kilimanjaro Chistian Medical Centre. A systematic random sampling was used to select the participants with indications of undergoing esophagogastroduodenoscopy. Questionnaires, stool and blood samples, and endoscopy were used to collect variable data. Numerical and categorical variables were summarized into narrations and tables. Logistic regression was used to assess the factors associated with H. pylori. RESULTS: The feco-prevalence of H. pylori was 43.4%. Chronic gastritis (51.1%) was the most common endoscopic pattern, whereas duodenal ulcers and gastric ulcers were significantly associated with H. pylori infection. Increasing in age (p <0.001) and blood group (p <0.001) were significantly associated with H. pylori infection in the adjusted analysis. CONCLUSION: The feco-prevalence of H. pylori is high in this setting. H. pylori stool antigen can be used as the initial workup for symptomatic patients before the initiation of proton pump inhibitors. Additionally, due to other causes of dyspepsia, it is advised that H. pylori stool antigen testing be part of the initial evaluation and esophagogastroduodenoscopy be considered in the absence of other alarm symptoms if symptoms persist despite an appropriate trial of medical therapy.

Methods: We systematically searched the PubMed, Web of Science, African Journals Online, Embase, Cochrane Library, and Google Scholar databases for studies conducted up to March 1, 2023, that estimated the prevalence of HBV in Tanzania based on HBV surface antigen measurements. The DerSimonian-Laird random effects model was used to estimate the overall prevalence of HBV with 95% confidence intervals (CIs). Potential sources of heterogeneity were also investigated. Results: Thirty-one studies with a total sample size of 37,988 were included in the meta-analysis. The overall average HBV prevalence estimate in Tanzania was 6.91% (95% CI = 5.18-8.86%). Subgroup analysis revealed the highest prevalence in the northern zone (9.32%, 95% CI; 2.24-20.36%), among the blood donors (18.72%, 95% CI: 17.43-20.05%) and among the community volunteers (8.76%, 95% CI: 4.55-14.15%). The lowest prevalence was observed in the lake zone at 4.66% (95% CI: 3.49-5.99) and in pregnant women at 4.72% (95% CI: 3.42-6.21). The overall between-study variability showed significant heterogeneity (I 2 = 97.41%, P < 0.001). Conclusions: Our results showed that Tanzania is a country with moderately high HBV endemicity, with large interregional differences and significantly high numbers of HBV infections within the community. This underscores the need for immediate development of targeted prevention strategies and further epidemiological studies to better understand the pattern of the disease.
RESUMEN
Introduction: Tracking of blood glucose levels by patients and care providers remains an integral component in the management of diabetes mellitus (DM). Evidence, primarily from high-income countries, has illustrated the effectiveness of self-monitoring of blood glucose (SMBG) in controlling DM. However, there is limited data on the feasibility and impact of SMBG among patients in the rural regions of sub-Saharan Africa. This study is aimed at assessing SMBG, its adherence, and associated factors on the effect of glycaemic control among insulin-treated patients with DM in northeastern Tanzania. Materials and Methods: This was a single-blinded, randomised clinical trial conducted from December 2022 to May 2023. The study included patients with DM who had already been on insulin treatment for at least 3 months. A total of 85 participants were recruited into the study and categorised into the intervention and control groups by a simple randomization method using numbered envelopes. The intervention group received glucose metres, test strips, logbooks, and extensive SMBG training. The control group received the usual care at the outpatient clinic. Each participant was followed for a period of 12 weeks, with glycated haemoglobin (HbA1c) and fasting blood glucose (FBG) being checked both at the beginning and at the end of the study follow-up. The primary and secondary outcomes were adherence to the SMBG schedule, barriers associated with the use of SMBG, and the ability to self-manage DM, logbook data recording, and change in HbA1c. The analysis included descriptive statistics, paired t-tests, and logistic regression. Results: Eighty participants were analysed: 39 in the intervention group and 41 in the control group. In the intervention group, 24 (61.5%) of patients displayed favourable adherence to SMBG, as evidenced by tests documented in the logbooks and glucometer readings. Education on SMBG was significantly associated with adherence. Structured SMBG improved glycaemic control with a HbA1c reduction of -1.01 (95% confidence interval (CI) -1.39, -0.63) in the intervention group within 3 months from baseline compared to controls of 0.18 (95% CI -0.07, 0.44) (p < 0.001). Conclusion: Structured SMBG positively impacted glycaemic control among insulin-treated patients with DM in the outpatient clinic. The results suggest that implementing a structured testing programme can lead to significant reductions in HbA1c and FBG levels. Trial Registration: Pan African Clinical Trials Registry identifier: PACTR202402642155729.

This study reports a case of female genital tuberculosis in a 46-year-old woman who presented to emergency department with abdominal pain and progressive abdominal distension. The patient was initially thought to have ovarian cancer based on clinical diagnosis and elevated cancer antigen-125 (CA-125) levels. Intra-operatively, no obvious ovarian tumor was encountered instead; disseminated creamy white patches on the uterus and left adnexa were seen. About 4500-mL straw-colored ascitic fluid and disseminated creamy white patches were also found on the bowels and omentum giving an impression of carcinomatosis. However, histopathology of the fallopian tube and ovary confirmed the diagnosis of female genital tuberculosis as the underlying cause. Female genital tuberculosis often mimics tumors in its clinical appearance and symptoms, leading to misdiagnosis and unnecessary treatment. The key to diagnosing female genital tuberculosis is being suspicious as it is challenging to diagnose through laboratory tests or radiology. The mainstay of treatment for female genital tuberculosis is a combination of four antituberculosis drugs. Consideration of female genital tuberculosis as a differential diagnosis in women presenting with symptoms mimicking reproductive tumors is highly recommended as highlighted in this case report.
RESUMEN
COVID-19 vaccination remains to be the most important intervention in the fight against the pandemic. The immunity among the vaccinated population and its durability can significantly vary due to various factors. This study investigated the humoral immune responses among individuals who received any of the COVID-19 vaccines approved for use in Tanzania. A total of 1048 randomly selected adults who received COVID-19 vaccines at different time points were enrolled and humoral immune responses (IR) were tested at baseline and three months later (960, 91.6%). The level of SARS-CoV-2 anti-spike/receptor binding domain (RBD) IgG, anti-nucleocapsid IgG, and IgM antibodies were determined using a commercially available chemiluminescent microparticle immunoassay. Descriptive data analysis was performed using STATA version 18 and R. At baseline, serum IgG against anti-spike/RBD was detected in 1010/1048 (96.4%) participants (95%CI: 94.9-97.5) and 98.3% (95%CI: 97.3-99) three months later. The IgG against the SARS-CoV-2 nucleocapsid proteins were detected in 40.8% and 45.3% of participants at baseline and follow-up, respectively. The proportion of seroconverters following vaccination and mean titers of anti-spike/RBD antibodies were significantly more among those who had past SARS-CoV-2 infection than in those with no evidence of past infection, (p < 0.001). Only 0.5% of those who had detectable anti-spike/RBD antibodies at baseline were negative after three months of follow-up and 1.5% had breakthrough infections. The majority of participants (99.5%) had detectable anti-spike/RBD antibodies beyond 6 months post-vaccination. The proportion of Tanzanians who mounted humoral IR following COVID-19 vaccination was very high. Seroconversions, as well as the mean titers and durability of humoral IR, were significantly enhanced by exposure to natural SARS-CoV-2 infection. In view of the limited availability of COVID-19 vaccines as well as challenges to completing subsequent doses, booster doses could only be suggested to high-risk groups.
RESUMEN
Summary: Myxedema coma is a severe complication of hypothyroidism, commonly affecting women over 60 years of age, causing slow, progressive multi-organ dysfunction, and mental deterioration. Due to improved diagnostics and treatment of hypothyroidism, myxedema coma has become uncommon. However, it is hardly reported in resource-limited settings. We present an elderly female with a history of total thyroidectomy due to multi-nodular goiter. She presented with features of heart failure, excessive weight gain, and cold sensation. Although the patient was on levothyroxine replacement therapy, her laboratory tests were suggestive of overt primary hypothyroidism. During the course of her hospitalization, she developed subcutaneous bleeding with frank hematuria. This led to an altered mental state and hypotension that were suggestive of myxedema coma. Stroke and pulmonary embolism were ruled out as potential differential diagnoses of her current state. She was treated with a high dose of oral levothyroxine followed by 150 µg of oral levothyroxine daily, which resulted in a favorable outcome despite being a fatal emergency. She was also treated with intravenous hydrocortisone and furosemide. Oral thyroid hormone replacement may be an effective option in those resource-limited settings where intravenous thyroid hormone replacement is not available. However, early diagnosis and treatment with an adequate dose of thyroid hormones are crucial to achieve a favorable outcome. Learning points: Myxedema coma is an uncommon complication of hypothyroidism with a fatal outcome. The diagnosis of myxedema coma is based on clinical suspicion, especially in patients with hypothyroidism and in the presence of precipitating factors. Although diagnostic and scoring criteria based on clinical, laboratory, and imaging features have been proposed, no consensus has been reached. This article shows an alternative treatment option for myxedema coma using oral levothyroxine, which led to a favorable outcome.
RESUMEN
BACKGROUND: Self medication is a common practice of using medicines without a medical supervision by the people themselves. Self medication is likely to happen when people feel unwell, it is worse in the population with poor helth seeking behavior. Therefore it is important to assess the prevalence and factors associated with self medication with antibiotics among University students in Moshi, Kilimanjaro Tanzania. METHODS: A cross sectional study was conducted from April-August 2019 at two Universities in Moshi, including one medical and one non medical. The study population were undergraduate students aged 18 and above, A self-filled questionnaire was used for data collection and data analyzed using the SPSS version 16 and association was tested using chi square. RESULTS: Out 374 students enrolled 187 from each University, 126 were female and 248 were male with age ranging from 19 to 35 years with mean age of 23.91 years. The prevalence of self medication with antibiotics was 57% and the most common used antibiotics was amoxicillin with prevalence of 32.08%. The common reported symptoms/diseases were headache (31.02%) followed by malaria and coughing with prevalence of 15.24% and 10.96% respectively. The commonest reasons of self medication reported to be emergency illness (38.77%) and delaying of hospital services (24.33%). The commonest effects reported among respondents which practiced self medication with antibiotics were worsening of the condition that they were suffering in (4.55%) and body rashes (2.67). There was no significant difference between self medication practices among medical and non medical students(p = 0.676). CONCLUSION: The prevalence of self medication with antibiotics was high among University students and there is no significant difference in both medical and non medical students. The most feared outcome on self medication with antibiotics is antibiotic drug resistance which leads to treatment failure along with high financial costs and increase mortality rate following microbial infections.

A giant lung bulla occupies at least a third of the lung space. We present a middle-aged man who lost consciousness during an air flight for 30 minutes, without any respiratory symptoms. An incidental finding on chest x-ray revealed a giant bulla and a chest computed tomography imaging confirmed the diagnosis and ruled out a tension pneumothorax. A giant lung bulla is an uncommon cause of loss of consciousness and may be suspected if it occurs during air travel.
RESUMEN
INTRODUCTION AND IMPORTANCE: Duodenal Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors of the digestive tract. The tumors are derived from interstitial cells of Cajal and usually they present as gastrointestinal bleeding or non-specific abdominal pain, but they can also be asymptomatic even when they have reached considerable size. CASE PRESENTATION: We report a case of a 40-year-old male presented to our emergency department after sustaining a stab wound on the abdomen. Abdominal imaging tests weren't done; instead an emergency laparotomy was undertaken upfront in an attempt to catch up with a "golden hour". Intra-operatively, an incidental solid mass measuring 4 × 5 cm was noted on the third/fourth portion of the interior duodenal flexure. Histopathologically, the lesion demonstrated spindled shaped cells which were immunopositive for positive CD117. The patient fared well postoperatively and during subsequent follow up visits. CLINICAL DISCUSSION: High-risk GISTs have malignant potential. In some cases, GIST is diagnosed as incidentally finding, mostly during surgical procedure, upper endoscopy or radiological studies related to GI tract. Surgical resection is recommended curative option and its extension depends on different factors. Tyrosine kinase inhibitors are of the utmost importance in high-risk and metastatic disease. CONCLUSION: Even considerably large duodenal GISTs can be asymptomatic, thus incidentally found during an abdomino-pelvic imaging tests. Histopathological evaluation of the operative specimen plays a key role in assessing the need of adjuvant therapy, with a significant impact on the patients' survival.
RESUMEN
BACKGROUND: Methadone therapy clinics have been recently introduced in Tanzania, aiming at reducing risk behaviors and infection rates of viral hepatitis and HIV among people who use drugs. The objective of this study was to estimate the prevalence, associated factors and knowledge level of these conditions among people who use drugs attending a methadone clinic in Tanzania. METHODS: We enrolled 253 People who using drugs receiving Methadone therapy. Clinical data was retrospectively collected from the medical records and face-to face interviews were conducted to determine the behavioral risk factors and respondents' knowledge on viral hepatitis and HIV. RESULTS: An overall seroprevalence of viral hepatitis (either hepatitis B surface antigen or anti-hepatitis C virus) was 6.3%, while that of hepatitis B virus mono infection was 3.5% and anti-hepatitis C antibodies was 3.5%. Seroprevalence of HIV was 12.6%. Viral hepatitis was strongly predicted by advanced age (> 35 years) (p = 0.02) and staying at Kirumba area (p = 0.004), and HIV infection was predicted by increased age (> 37 years) (p = 0.04) and female sex (p < 0.001). Regarding the knowledge of viral hepatitis, majority of the respondents were unaware of the transmission methods and availability of hepatitis B virus vaccines and only 17% were classified as well informed (provided ≥4 correct answers out of 7 questions). Good knowledge was highly predicted by higher education level of the individual (p = 0.001). CONCLUSIONS: Despite the efforts to curb viral hepatitis and HIV infections through Methadone clinics, infection rates among people who use drugs are still high and the general knowledge on preventive measures is inadequate.

BACKGROUND: Hypertension (HTN) can be present in up to two-thirds of patients living with diabetes mellitus (DM). It is a risk factor for the development of diabetes as well as complications like coronary artery disease (CAD), nephropathy, retinopathy, and neuropathy. Hypertension is treatable, and the degree to which it is controlled determines the risk of development of cardiovascular diseases and other complications in a given individual patient. Even though antihypertensive drugs are available and issued to hypertensive diabetic patients, the rate of control of HTN is often inadequate. The aim of this study was to assess the prevalence of suboptimal blood pressure (BP) control, its associated factors, and the choice of antihypertensive drugs among type 2 DM patients at Kilimanjaro Christian Medical Centre (KCMC). METHODS: A hospital-based cross-sectional study was conducted at the KCMC diabetes clinic from October 2018 to March 2019 among type 2 DM patients with HTN based on the inclusion criteria. Data were collected using structured questionnaires, and written informed consent was obtained. Suboptimal BP was defined as BP levels ≥ 140/90 mmHg according to the American Diabetes Association guideline published in 2018. Data analysis was done using the Statistical Package for the Social Sciences (SPSS) version 25. Chi-square analysis was done to identify the independent predictors of BP control, and a p value of <0.05 was considered to be statistically significant. RESULTS: The data of 161 participants was analysed; the mean age was 63.9 ± 20.2 years, with the majority being females (67.1%). Despite all participants being on different classes of antihypertensives, 57.8% had suboptimal BP control. Among the participants with good BP control, 52.7% were on angiotensin-converting enzyme inhibitors (ACE-I). Poor diabetes control was observed in 50.1% participants as indicated by elevated glycated haemoglobin. CONCLUSION: This study demonstrated that BP control in type 2 DM patients was suboptimal in more than half of the participants. The study showed that the use of ACE-I or angiotensin II receptor blockers (ARBs) in the majority of DM patients has a good impact in the control of blood pressure. The early initiation of ACE-I or ARBs among the diabetic patients will improve the optimal BP control.

BACKGROUND: Albumin is an important protein that transports hormones, fatty acids, and exogenous drugs; it also maintains plasma oncotic pressure. Albumin is considered a negative active phase protein because it decreases during injuries and sepsis. In spite of other factors predicting surgical outcomes, the effect of pre and postoperative serum albumin to surgical complications can be assessed by calculating the percentage decrease in albumin (delta albumin). This study aimed to explore perioperative serum albumin as a predictor of adverse outcomes in major abdominal surgeries. METHODS: All eligible adult participants from Kilimanjaro Christian Medical Centre Surgical Department were enrolled in a convenient manner. Data were collected using a study questionnaire. Full Blood Count (FBP), serum albumin levels preoperatively and on postoperative day 1 were measured in accordance with Laboratory Standard Operating Procedures (SOP). Data was entered and analyzed using STATA version 14. Association and extent of decrease in albumin levels as a predictor of surgical site infection (SSI), delayed wound healing and death within 30 days of surgery was determined using ordinal logistic regression models. In determining the diagnostic accuracy, a Non-parametric Receiver Operating Curve (ROC) model was used. We adjusted for ASA classification, which had a negative confounding effect on the predictive power of the percent drop in albumin to adverse outcomes. RESULTS: Sixty one participants were studied; the mean age was 51.6 (SD16.3), the majorities were males 40 (65.6%) and post-operative adverse outcomes were experienced by 28 (45.9%) participants. In preoperative serum albumin values, 40 (67.8%) had lower than 3.4 g/l while 51 (91%) had postoperative albumin values lower than 3.4 g/l. Only 15 (27.3%) had high delta albumin with the median percentage value of 14.77%. Delta albumin was an independent significant factor associated with adverse outcome (OR: 6.68; 95% CI: 1.59, 28.09); with a good predictive power and area under ROC curve (AUC) of 0.72 (95% CI 0.55 0.89). The best cutoff value was 11.61% with a sensitivity of 76.92% and specificity of 51.72%. CONCLUSION: Early perioperative decreases in serum albumin levels may be a good, simple and cost effective tool to predict adverse outcomes in major abdominal surgeries.

Mass deworming against soil-transmitted helminthiasis, including Ascaris lumbricoides (AL), is one of the largest public health interventions in low- and middle-income countries. The prevalence of A. lumbricoides in Tanzania is 6.8%. We present a 3-year-old male of a known Tanzanian nomadic tribe (Masaai tribe) with history of missed deworming, who was brought to the emergency department with a 3-day history of constipation, nonprojectile, bilious vomiting, generalized abdominal distension and pain.He was diagnosed with intestinal obstruction by the use of a plain abdominal X-ray, which revealed marked gaseous distension of the stomach and bowels without significant air-fluid levels. He was initially treated with intravenous ceftriaxone 50 mg/kg, metronidazole 15 mg/kg and acetaminophen 15 mg/kg. An explorative laparotomy was then performed. Intraoperative findings demonstrated a dense collection of A. lumbricoides worms in the gangrenous proximal jejunum and duodenum. Thorough abdominal lavage was carried out and abdomen was closed.
RESUMEN
INTRODUCTION: Heart failure (HF) is characterized by frequent episodes of decompensation, leading to a high hospitalization burden. More than 50% of index hospitalizations for HF patients return within 6 months of discharge. Once the patient is readmitted, the risk of further disease progression and the mortality rate are increased. A lot of patients are readmitted due to factors such as poor medication adherence, infections, or worsening comorbidities. The aim of our study was to identify the inpatient burden of HF readmission and to identify the factors associated with early readmission. METHODS: A hospital-based cross-sectional analytical study was conducted from November 2018 to April 2019 within the medical wards at Kilimanjaro Christian Medical Centre (KCMC), which is a teaching and referral hospital in north-eastern Tanzania. The study population included all patients with HF admitted within the medical ward. Data were collected using questionnaires and blood and radiological investigations, and analysis was done using Statistical Package for Social Science (SPSS) version 25. Chi-square test was used to compare proportions of categorical variables. Logistic regression was used to determine the likelihood for readmission, and p-value of <0.05 was considered to be statistically significant. RESULTS: A total of 353 patients were identified with HF, of whom 136 (38.5%) had a previous admission. Of the 136 patients analysed, the mean age was 62.8 years (SD 17.1), and 86 (63.2%) were females. Within 30 days after discharge, 34 (25.0%) of the patients were readmissions. Factors for early readmission were unemployment (OR = 2.38, 95% CI = 1.02-5.54, p = 0.043), poor medication adherence (OR = 3.87, 95% CI = 1.67-8.97, p = 0.002), absence of angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) (OR = 2.40, 95% CI = 1.09-5.31, p = 0.030), and pleural effusion (OR 3.25, 95% CI = 1.44-7.32, p = 0.004). CONCLUSION: Heart failure is a burden due to a large number of admissions and readmissions. Factors such as poor medication adherence and absence of adequate HF therapy, especially the absence of regimes containing ACEI or ARB, need to be targeted to reduce the number of readmissions. This will help reduce the risk of further decompensations, disease progression, and mortality rate.
RESUMEN
OBJECTIVE: Diabetic peripheral neuropathy (DPN) is a common microvascular complication of diabetes mellitus (DM) and may progress to diabetic foot, which frequently leads to amputation and/or disability and death. Data is scanty on the burden of diabetic peripheral neuropathy in Tanzania. The aim of this study was to assess the burden of peripheral neuropathy, its severity, and the associated factors. METHODS: The study was a cross-sectional hospital-based study and was carried out from October 2017 to March 2018 among adolescent and adult patients attending Kilimanjaro Christian Medical Center (KCMC) diabetes clinic. RESULTS: A total of 327 diabetic patients, females n=215 (65.7%) and males n=121 (34.3%), were included in the study. The mean age was 57.2 yrs. A total of 238 (72%) had type 2 and 89 (27.2%) had type1 DM. The prevalence of peripheral neuropathy was 72.2% of whom 55% were severe, 19% were moderate, and 26% were mild. The severity of neuropathy increased with the increase in age >40 years (p < 0.001) and increase in body mass index (p<0.001) and duration of diabetes; duration >7 years (p <0.006). The main associated factors were age >40 years, OR 2.8 (1.0-7.7), >60 years, OR 6.4 (2.3-18.2), obesity, OR 6.7 (0.9-27.7), and hypertension, OR 4.3 (2.2-8.2). CONCLUSION: More than half of the patients included in this study were found to have neuropathy, nearly half of whom presented with the severe form. The main risk factors were increasing age, increasing duration of diabetes, obesity, and hypertension. Diabetic peripheral neuropathy is underdiagnosed in northern Tanzania where screening for neuropathy is not routinely done.
RESUMEN
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.

BACKGROUND: Kaposi's sarcoma (KS) is a multifocal angioproliferative tumor involving blood and lymphatic vessels, caused by Human Herpes Virus-8 (HHV-8). KS is an important AIDS-defining tumor with high prevalence in Sub-Saharan Africa, including Tanzania which has high HIV and HHV-8 sero-prevalence. It is critically important to monitor the prevalence of AIDS-defining tumors, such as KS, in the age of HIV/AIDS. We studied the prevalence of KS and associated risk factors among HIV-positive patients at Kilimanjaro Christian Medical Centre (KCMC), a referral hospital in northern Tanzania, over the period from January 2012 to December 2015. METHODS: This was a retrospective hospital-based cross-sectional study to determine the prevalence of KS among HIV/AIDS patients between 2012 and 2015. The study included 1100 HIV patients' data which were collected at the Infectious Disease Clinic (IDC) from patients' files. Stata version 13 (StataCorp LP, Texas 77,845 USA) was used for all statistical analyses. The prevalence of KS was calculated across levels of a number of categorical variables. Logistic regression was performed to determine relative risk of KS for all characteristics. We included all variables with p-values ≤10% in the multivariate analysis, including ART use, as this is considered to have an influence on KS. In the multivariate analysis, statistical significance was established based on a two-tailed p-value ≤5%. All patients' notes were kept confidential as per the Helsinki declaration. RESULTS: Our results revealed a 4.6% prevalence of KS at KCMC hospital, between January 2012 and December 2015, 51(4.6%) patients were diagnosed with KS out of 1100 HIV-positive patients. The study further revealed that KS in HIV patients was most associated with low CD4 cell count (less than or equal to 200 cells/µl). Moreover, women were more likely than men to diagnosed with KS, with higher odds significantly associated with KS (OR 0.42, p < 0.009). Increased age, above 35 years, among the HIV seropositive patients was significantly associated with KS (OR 25.67, p < 0.007). HIV patients who were none smokers were more likely to suffer from KS compared to HIV smokers (OR 0.41, p < 0.010). CONCLUSION: KS remains a common malignant vascular tumor commonly associated with HIV/AIDS in Tanzania. Our study highlights the need for continued efforts to combat HIV, as well as associated diseases such as KS. Continued availability of ART (Anti-Retroviral Therapy) to HIV/AIDS patients, and test reagents for CD4 cell count and viral load determination are important measures to alleviate the suffering of these patients. Furthermore, studies to gather more evidence on ART resistance are highly needed to guide treatment choices.

Antibiotic dispensing without a prescription poses a threat to public health as it leads to excessive antibiotic consumption. Inappropriate antibiotic availability to the community has been documented to be amongst drivers of antimicrobial resistance emergence. Community pharmacies are a source of antibiotics in low and middle-income countries (LMICs). We aimed at assessing antibiotic dispensing practices by community pharmacy retailers in Moshi urban, Kilimanjaro, Tanzania and recommend interventions to improve practice. Using a Simulated Client (SC) Method, an observational cross-sectional survey of antibiotic dispensing practices was conducted from 10th June to 10th July 2017. Data analysis was done using Stata 13 (StataCorp, College Station, TX, USA). A total of 82 pharmacies were visited. Part I pharmacies were 26 (31.71%) and 56 (68.29%) were part II. Overall 92.3% (95% CI 77.8-97.6) of retailers dispensed antibiotics without prescriptions. The antibiotics most commonly dispensed without a prescription were ampiclox for cough (3 encounters) and azithromycin for painful urination (3 encounters). An oral third generation cephalosporin (cefixime) was dispensed once for painful urination without prescription by a part I pharmacy retailer. Out of 21, 15(71.43%) prescriptions with incomplete doses were accepted and had antibiotics dispensed. Out of 68, 4(5.9%) retailers gave instructions for medicine use voluntarily. None of the retailers voluntarily explained drug side-effects. In Moshi pharmacies, a high proportion of antibiotics are sold and dispensed without prescriptions. Instructions for medicine use are rarely given and none of the retailers explain side effects. These findings support the need for a legislative enforcement of prescription-only antibiotic dispensing rules and regulations. Initiation of clinician and community antibiotic stewardship and educational programs on proper antibiotic use to both pharmacists and public by the regulatory bodies are highly needed.

Bee sting has been identified as among causative agents of nephrotoxic acute tubular necrosis which may lead to acute kidney injury. Bee envenomation has medicinal properties but when a higher dose is inoculated may cause severe anaphylaxis with very poor prognosis. We report a 12-year-old boy with acute kidney injury following multiple bee stings who recovered well after hemodialysis.
