Epidemiology, clinical features and outcome of stroke in rural versus urban hospitals in Cameroon.

OBJECTIVES: Stroke is a major public health problem worldwide with disparities between urban and rural areas. The aim of this study was to compare the epidemiological, clinical features and outcomes of stroke between rural and urban hospitals in Cameroon. MATERIALS AND METHODS: We conducted a retrospective cohort study at the Douala General Hospital (urban) and Ad Lucem Hospital of Banka (rural) from January 1st, 2014, to December 31st, 2019. The medical records of all patients admitted for stroke, and meeting the inclusion criteria were reviewed. Diagnosis of stroke was based on brain imaging and/or the World Health Organization definition. Data were analyzed using SPSS version 20.0. RESULTS: Among the 15277 files reviewed, 752 were included with 623 cases (82.80%) in urban areas. The percentage of patients hospitalized for stroke were 9.06% and 2.85% in urban and rural hospitals respectively. The frequency of patients admitted for severe stroke (Glasgow coma scale ≤ 8) was higher in the rural hospital (p = 0.004). In-hospital mortality (p = 0.010), cumulative mortality at one-month (p = 0.018), poor functional recovery (p = 0.002), one-year stroke recurrence (p = 0.020) were significantly higher in rural setting. Undefined stroke was predictor of mortality in the rural hospital, while hemorrhagic stroke was predictor of mortality at one-month in the urban hospital. CONCLUSIONS: Stroke cases were significantly more severe with poor outcomes in the rural hospital. Efforts are needed to improve prevention, and access to stroke care for communities, especially in rural setting.

Diagnosis and treatment challenges of autism spectrum disorder at a reference hospital in Douala, Cameroon.

BACKGROUND: Autism spectrum disorder (ASD) is a neurodevelopmental disability associated with deficiency in social interaction, unusual development of social communication, and restricted or repetitive behaviors, interests and activities. This study aimed to describe management of pediatric ASD in Cameroon, a resource-constrained Central Africa country. METHODS: A retrospective study was conducted between December 2021 and May 2022 at the Pediatrics department of a reference hospital in the town of Douala. Data of interest of children with ASD were collected through eligible medical records and telephone discussions with their parents/guardians. RESULTS: Medical records of 145 children with ASD aged 2-15 years were included in the study, giving a hospital ASD prevalence of 3.7%. Time delay between parental concerns and hospital management was specified in 69 (47.58%) children, and among them 38 (55.07%) had a mean delay ± SD was less than five months. Children were mainly males (76%) and aged 4-5 years (37.93%), with mean age ± SD of 44.4 ± 22.2 months old. The main consultation reason was delayed language development (100%). Mean time delay between parental concerns and the first medical consultation was 18 months (range 1-60 month). Attention deficit hyperactivity disorder were found in 68.18% of children aged ≥ 6 years old. Neuropsychology (66.2%) was the most frequently used intervention. Some children were treated using traditional medicine. CONCLUSIONS: Management of pediatric ASD is strongly influenced by socioeconomic and cultural context. It is crucial to implement behavioral change campaigns in community, organize training sessions to medical staff on diagnosis and treatment of ASD, and provide specialized centers with skilled staff and equipped material.

Antifungal Combinations for Treatment of Cryptococcal Meningitis in Africa.

BACKGROUND: Cryptococcal meningitis accounts for more than 100,000 human immunodeficiency virus (HIV)-related deaths per year. We tested two treatment strategies that could be more sustainable in Africa than the standard of 2 weeks of amphotericin B plus flucytosine and more effective than the widely used fluconazole monotherapy. METHODS: We randomly assigned HIV-infected adults with cryptococcal meningitis to receive an oral regimen (fluconazole [1200 mg per day] plus flucytosine [100 mg per kilogram of body weight per day] for 2 weeks), 1 week of amphotericin B (1 mg per kilogram per day), or 2 weeks of amphotericin B (1 mg per kilogram per day). Each patient assigned to receive amphotericin B was also randomly assigned to receive fluconazole or flucytosine as a partner drug. After induction treatment, all the patients received fluconazole consolidation therapy and were followed to 10 weeks. RESULTS: A total of 721 patients underwent randomization. Mortality in the oral-regimen, 1-week amphotericin B, and 2-week amphotericin B groups was 18.2% (41 of 225), 21.9% (49 of 224), and 21.4% (49 of 229), respectively, at 2 weeks and was 35.1% (79 of 225), 36.2% (81 of 224), and 39.7% (91 of 229), respectively, at 10 weeks. The upper limit of the one-sided 97.5% confidence interval for the difference in 2-week mortality was 4.2 percentage points for the oral-regimen group versus the 2-week amphotericin B groups and 8.1 percentage points for the 1-week amphotericin B groups versus the 2-week amphotericin B groups, both of which were below the predefined 10-percentage-point noninferiority margin. As a partner drug with amphotericin B, flucytosine was superior to fluconazole (71 deaths [31.1%] vs. 101 deaths [45.0%]; hazard ratio for death at 10 weeks, 0.62; 95% confidence interval [CI], 0.45 to 0.84; P=0.002). One week of amphotericin B plus flucytosine was associated with the lowest 10-week mortality (24.2%; 95% CI, 16.2 to 32.1). Side effects, such as severe anemia, were more frequent with 2 weeks than with 1 week of amphotericin B or with the oral regimen. CONCLUSIONS: One week of amphotericin B plus flucytosine and 2 weeks of fluconazole plus flucytosine were effective as induction therapy for cryptococcal meningitis in resource-limited settings.

Estimation and determinants of direct medical costs of ischaemic heart disease, stroke and hypertensive heart disease: evidence from two major hospitals in Cameroon.

BACKGROUND: Cardiovascular disease (CVD) is the largest contributor to the non-communicable diseases (NCD) burden in Cameroon, but data on its economic burden is lacking. METHODS: A prevalence-based cost-of-illness study was conducted from a healthcare provider perspective and enrolled patients with ischaemic heart disease (IHD), ischaemic stroke, haemorrhagic stroke and hypertensive heart disease (HHD) from two major hospitals between 2013 and 2017. Determinants of cost were explored using multivariate generalized linear models. RESULTS: Overall, data from 850 patients: IHD (n = 92, 10.8%), ischaemic stroke (n = 317, 37.3%), haemorrhagic stroke (n = 193, 22.7%) and HHD (n = 248, 29.2%) were analysed. The total cost for these CVDs was XAF 676,694,000 (~US$ 1,224,918). The average annual direct medical costs of care per patient were XAF 1,395,200 (US$ 2400) for IHD, XAF 932,700 (US$ 1600) for ischaemic stroke, XAF 815,400 (US$ 1400) for haemorrhagic stroke, and XAF 384,300 (US$ 700) for HHD. In the fully adjusted models, apart from history of CVD event (ß = - 0.429; 95% confidence interval - 0.705, - 0.153) that predicted lower costs in patients with IHD, having of diabetes mellitus predicted higher costs in patients with IHD (ß = 0.435; 0.098, 0.772), ischaemic stroke (ß = 0.188; 0.052, 0.324) and HHD (ß = 0.229; 0.080, 0.378). CONCLUSIONS: This study reveals substantial economic burden due to CVD in Cameroon. Diabetes mellitus was a consistent driver of elevated costs across the CVDs. There is urgent need to invest in cost-effective primary prevention strategies in order to reduce the incidence of CVD and consequent economic burden on a health system already laden with the impact of communicable diseases.

The Prognostic Value of Serum Uric Acid in the Acute Phase of Ischemic Stroke in Black Africans.

BACKGROUND: The association between hyperuricemia and stroke outcome still remains controversial worldwide. This study aims to determine the prevalence of hyperuricemia and its association with the outcome of patients with acute ischemic stroke in a tertiary care hospital. METHODS: This was a hospital-based prospective cohort study that included patients with ischemic stroke with baseline uric acid levels and 3-month post-stroke follow-up data. Associations between hyperuricemia and stroke outcomes were analyzed using multiple logistic regression, Kaplan-Meier, and Cox proportional hazards regression analysis. RESULTS: A total of 480 patients were reviewed with a mean age of 62.8 ± 13.3 years. The prevalence of hyperuricemia was 52.3% with mean uricemia of 71.1 ± 25.3 mg/dL. There was a significant association between hyperuricemia and mortality with unadjusted odds ratio (OR) = 4.120 [95% (confidence interval [CI]: 2.466-7.153); P = .001)], but on multivariate analysis, hyperuricemia was not an independent predictor of stroke mortality [OR = 1.270 (CI: .547-2.946); P = .578)]. An independent association between increasing uric acid levels and mortality was noted on Cox proportional hazards regression; adjusted hazard ratio (95% CI) of 3.395 (2.114-5.452), P value greater than .001. Stroke mortality significantly increased across higher uric acid quintiles in patients with acute stroke (P < .001). Hyperuricemia was an independent predictor of poor functional outcome within 3 months after stroke with adjusted OR (95% CI) of 2.820 (1.359-5.851); P = .005. CONCLUSIONS: Half of black African patients with ischemic stroke present with hyperuricemia, and hyperuricemia is a predictor of mortality and adverse functional outcomes. Further studies are therefore warranted to determine whether reducing hyperuricemia after stroke would be beneficial within our setting.

Acute Stroke Patients with Newly Diagnosed Diabetes Mellitus Have Poorer Outcomes than Those with Previously Diagnosed Diabetes Mellitus.

BACKGROUND: Diabetes mellitus (DM) is associated with poor outcomes in acute stroke patients (ASPs). This study aims to determine the prevalence of NDDM in the ASPs and to compare the outcome in NDDM and previously diagnosed DM (PDDM) in Cameroon. METHODS AND MATERIALS: This was a hospital-based prospective cohort study that included ASPs with NDDM and PDDM. Outcome data were collected within 3 months of stroke onset. Chi-square and t tests were used for comparisons, whereas survival analysis was performed using Cox regression and Kaplan-Meier analysis. RESULTS: Of the 701 ASPs included, 24.8% had PDDM (n = 174) and 9.4% NDDM (n = 66). NDDM had a higher mortality rate on admission and 3 months after stroke (P < .05). PDDM were more likely to survive within 3 months after stroke onset (log-rank test P = .008). The risk of dying among NDDM was increased (adjusted hazard ratio = 1.809; 95% confidence interval: 1.1532.839; P = .010). NDDM were more likely to have higher mean National Institutes of Health Stroke Scale and modified Rankin score (P < .05) on admission. PDDM were more likely to develop urinary tract infections during hospitalization (P = .015). There was no significant difference between functional outcome on admission and 3 months after stroke (P > .05). CONCLUSION: NDDM are associated with increased mortality and are more likely to have poorer functional outcomes and more severe stroke than those with PDDM.

Gender-Related Differences and Short-Term Outcome of Stroke: Results from a Hospital-Based Registry in Sub-Saharan Africa.

BACKGROUND: Studies suggest that sex differences have an impact on patients with stroke, but existing data in Africa remain inconclusive about this inference. OBJECTIVES: To study sex differences in terms of the clinical profile and short-term outcome of stroke in the Douala General Hospital, Cameroon. METHODS: A hospital-based prospective cohort study was carried out in a tertiary care hospital over an 8-year period, which included all patients admitted for confirmed acute stroke. Information about the history of stroke with emphasis on clinical profile and outcome was collected. Descriptive statistics, t test, and chi square test were used for comparisons, while the Kaplan-Meier curve was used for survival rate analysis. RESULTS: Of the 818 patients included, 455 (55.6%) were male patients. When compared to males, female patients are more likely to experience a stroke at an older age (mean age 62.3 ± 14.1 vs. 58.4 ± 12.9 years, p < 0.001), to be unmarried, to remain unemployed, and to have higher rates of cardio-embolic stroke (p = 0.049), body mass index (p = 0.031), altered levels of consciousness at presentation (p = 0.005), higher mean HDL cholesterol levels (p = 0.001), and in-hospital complications (p = 0.011), especially urinary tract infections (p = 0.018). Males were more likely to have health insurance, to smoke, to consume alcohol (p < 0.001), and to have higher rates of dysarthria (p = 0.004), higher mean uric acid (p = 0.013), and creatinine (p < 0.001) concentrations. Ischemic and hemorrhagic strokes were more prevalent in men (p = 0.003). There are no sex differences in terms of stroke severity, length-of-hospital stay, case fatality, and functional outcome on admission. CONCLUSIONS: Sex differences exist in the clinical profile of stroke but not in the outcome. Knowledge of these differences could help influence stroke prevention, thereby improving stroke burden in Africa.

HIV-associated sensory neuropathy in HIV-1 infected patients at the Douala General Hospital in Cameroon: a cross-sectional study.

BACKGROUND: Peripheral neuropathy (PN) which is the most common neurological complication of HIV infection is under recognised and undertreated especially in resource limited settings. This ailment which has a negative impact on the quality of life of HIV/AIDS patients exists in different clinical patterns of which HIV-associated Sensory neuropathy (HIV-SN) is the most common affecting up to two thirds of patients with advanced disease in some settings. In Cameroon where HIV is a major public health problem, the burden of HIV-SN has not yet been well defined. METHODS: Using the Brief Peripheral Neuropathy Screening (BPNS) tool validated by the AIDS Clinical Trial Group (ACTG) we carried out a cross sectional study to determine the prevalence of HIV-SN and its associated factors among HIV-1 patients at the Douala General Hospital between 1st July and 31st October 2011. HIV-SN was defined as the presence of neuropathic symptoms and at least an abnormal perception of vibrations of a 128Hz tuning fork on the great toe or abnormal ankle reflexes or both and expressed as a percentage of the study population. RESULTS: Out of 295 patients studied, 21% had HIV-SN. In HIV-SN patients the median duration of HIV infection was 79.8 months (IQR 46 - 107.5) and their median CD4 count 153cells/µL (IQR 80 - 280). Patient recall and clinical chart review showed that, 83.9% had neuropathic symptoms prior to HAART initiation and 16.1% after HAART initiation. Low CD4 count, history of alcohol intake and history of anti-tuberculosis treatment were strongly associated with HIV-SN (AOR 2.5, 2.8 and 2.9 respectively). CONCLUSIONS: HIV-SN is common among patients with advanced HIV infection in Cameroon. This simple diagnostic tool (BPNS) should therefore be routinely used to detect those with HIV-SN or at risk so as to minimise the negative impact it has on their quality of life.

Fungal Burden and Raised Intracranial Pressure Are Independently Associated With Visual Loss in Human Immunodeficiency Virus-Associated Cryptococcal Meningitis.

Among 472 patients with human immunodeficiency virus-associated cryptococcal meningitis, 16% had severe visual loss at presentation, and 46% of these were 4-week survivors and remained severely impaired. Baseline cerebrospinal fluid opening pressure ≥40 cmH2O (adjusted odds ratio [aOR], 2.56; 95% confidence interval [CI], 1.36-4.83; P = .02) and fungal burden >6.0 log10 colonies/mL (aOR, 3.01; 95% CI, 1.58-5.7; P = .003) were independently associated with severe visual loss.

The prognostic value of serum uric acid in the acute phase of hemorrhagic stroke patients in black Africans.

INTRODUCTION: Very few studies have been conducted to evaluate the prevalence of hyperuricemia and its impact on the prognosis amongst acute hemorrhagic stroke (AHS) patients. The objectives was to determine the prevalence of hyperuricemia in AHS patients and examined the association between hyperuricemia and stroke outcomes in the Douala General Hospital (DGH). METHODS: This was a hospital based prospective cohort which included AHS patients with baseline SUA levels and 3 months post stroke follow-up data. SUA values were divided into quintiles. Associations between hyperuricemia and stroke outcomes were analyzed using multiple logistic regression and survival analysis (cox regression and Kaplan Meier). RESULTS: A total of 221 AHS patients were reviewed with a mean age of 55.8±11.8 years. The prevalence of hyperuricemia among AHS patients was 34.4% with mean SUA level of 376.8±131.9 µmol/l. On multivariate analysis, hyperuricemia was not independently associated with early death [(OR = 1.072 (CI: 0.370-3.056; p = 0.897)] and poor functional outcome [(OR=2.487 (CI: 0.771-8.699; p = 0.154)] after hemorrhagic stroke. No significant increase in stroke deaths was observed across higher SUA quintiles amongst hemorrhagic stroke patients (p = 0.326). No statistically significant correlation was observed between SUA level and NIHSS (r = 0.063, p = 0.353) and between SUA level and mRS (r = 0.030, p = 0.662) in hemorrhagic stroke. CONCLUSION: About one third of patients present with hyperuricemia in the acute phase of hemorrhagic stroke. Hyperuricemia can act as risk factor for stroke because of its relationship with CVRFs but hyperuricemia has no impact on the severity and short-term outcome amongst black African hemorrhagic stroke patients.

Leave no one behind: response to new evidence and guidelines for the management of cryptococcal meningitis in low-income and middle-income countries.

In 2018, WHO issued guidelines for the diagnosis, prevention, and management of HIV-related cryptococcal disease. Two strategies are recommended to reduce the high mortality associated with HIV-related cryptococcal meningitis in low-income and middle-income countries (LMICs): optimised combination therapies for confirmed meningitis cases and cryptococcal antigen screening programmes for ambulatory people living with HIV who access care. WHO's preferred therapy for the treatment of HIV-related cryptococcal meningitis in LMICs is 1 week of amphotericin B plus flucytosine, and the alternative therapy is 2 weeks of fluconazole plus flucytosine. In the ACTA trial, 1-week (short course) amphotericin B plus flucytosine resulted in a 10-week mortality of 24% (95% CI -16 to 32) and 2 weeks of fluconazole and flucytosine resulted in a 10-week mortality of 35% (95% CI -29 to 41). However, with widely used fluconazole monotherapy, mortality because of HIV-related cryptococcal meningitis is approximately 70% in many African LMIC settings. Therefore, the potential to transform the management of HIV-related cryptococcal meningitis in resource-limited settings is substantial. Sustainable access to essential medicines, including flucytosine and amphotericin B, in LMICs is paramount and the focus of this Personal View.

Multiple cerebral infarction revealing Takayasu's disease: a case report in a 32-year-old man from Cameroon, sub-Saharan Africa.

This case suggests that young patients with few vascular risk factors, and who present with acute stroke syndrome involving more than one vascular territory should be screened for an inflammatory or infectious cause.

Prevalence and risk factors of peripheral artery disease in black Africans with HIV infection: a cross-sectional hospital-based study.

BACKGROUND: The prevalence of peripheral artery disease (PAD) is not well known among HIV-infected patients in Africa. The aim of this study was to determine the prevalence and associated risk factors of PAD among HIV-infected patients at the Douala General Hospital (DGH). METHODS: This was a cross-sectional descriptive and analytic study between November 2015 and April 2016. We recruited patients aged ≥21 years, diagnosed with HIV infection, and who were receiving care at the DGH. We collected sociodemographic data and past medical history of patients. We measured their ankle-brachial index (ABI). We defined PAD as an ABI <0.9. We also measured their fasting blood glucose and lipid profile. RESULTS: We recruited 144 patients for this study. The mean age was 46±9 years, and 72.2% were females. Of which, 89% were on antiretroviral treatment (ARV). Their mean CD4+ T lymphocytes count was 451±306 cells/mm3. Their mean ABI was 1.12±0.17 and 1.07±0.11, respectively, on the left and right legs (P>0.05). The prevalence of PAD was 6.9% (95% CI: 3.4-12.4), and 60% of patients with PAD were symptomatic. After adjusting for age, sex and ARV, ARV treatment was protective (aOR: 0.18, [95% CI: 0.04-0.82], P=0.034), while WHO stages III or IV was associated with PAD (aOR: 11.1, [95% CI: 2.19-55.92], P=0.004). CONCLUSION: The prevalence of PAD was not as high as expected in this group of patients with high cardiovascular risk infected with HIV. Advanced HIV disease was associated with PAD, while ARV was protective.

Serum Uric Acid Is Associated with Poor Outcome in Black Africans in the Acute Phase of Stroke.

BACKGROUND: Prognostic significance of serum uric acid (SUA) in acute stroke still remains controversial. OBJECTIVES: To determine the prevalence of hyperuricemia and its association with outcome of stroke patients in the Douala General Hospital (DGH). METHODS: This was a hospital based prospective cohort study which included acute stroke patients with baseline SUA levels and 3-month poststroke follow-up data. Associations between high SUA levels and stroke outcomes were analyzed using multiple logistic regression and survival analysis (Cox regression and Kaplan-Meier). RESULTS: A total of 701 acute stroke patients were included and the prevalence of hyperuricemia was 46.6% with a mean SUA level of 68.625 ± 24 mg/l. Elevated SUA after stroke was associated with death (OR = 2.067; 95% CI: 1.449-2.950; p < 0.001) but did not predict this issue. However, an independent association between increasing SUA concentration and mortality was noted in a Cox proportional hazards regression model (adjusted HR = 1.740; 95% CI: 1.305-2.320; p < 0.001). Furthermore, hyperuricemia was an independent predictor of poor functional outcome within 3 months after stroke (OR = 2.482; 95% CI: 1.399-4.404; p = 0.002). CONCLUSION: The prevalence of hyperuricemia in black African stroke patients is quite high and still remains a predictor of poor outcome.

Cross-sectional assessment of three commonly used measures of adherence to combination antiviral therapy in a resource limited setting.

Nowadays, global coverage of combination antiretroviral therapy (cART) has increased due to a continuous process to scale up access. This increase has potentially transformed HIV-infection from a fatal to a chronic disease: a transformation only possible if the prescribed medications are taken accordingly. We therefore evaluated optimal adherence to cART by three commonly used methods: visual analogue scale (VAS), four days recall (FDR) and clinic attendance (CA) for the last six months in 301 HIV-infected patients on cART for at least six months at the Douala General Hospital, Cameroon. Optimal adherence was defined to be greater than or equal to the 95th percentile estimate of each method. We found that 70.8% of our study population was female. The mean age was 40.8 years (SD 10.5) and 85% were on first line cART. Median CD4 count was 397 cells/ml (252-559). Optimal adherence by VAS, FDR and CA, was 68.1%, 83.4%, and 73.4%, respectively. VAS and FDR inter-correlated strongly (Pearson's Chi square coefficient, r = 0.58, p < 0.001). Higher CD4 count above 200 cells/ml was associated with optimal adherence by CA (Adjusted Odds Ratio [AOR]:2.6 (95% CI: 1.2-5.3, p < 0.001)). As high optimal adherence to cART is associated with good clinical outcome in HIV patients, simple methods such as the VAS for evaluating adherence, should be integrated to the HIV clinic of the Douala General Hospital.

Overweight and obesity in children aged 3-13 years in urban Cameroon: a cross-sectional study of prevalence and association with socio-economic status.

BACKGROUND: Childhood overweight/obesity is increasing rapidly in developing countries. There is a need to provide more evidence on its burden in sub-Saharan Africa, and to identify associated factors in order to set preventive measures. We aimed to determine the prevalence of overweight/obesity and assess its association with the socioeconomic status in nursery and primary school children in urban Cameroon. METHODS: In this cross-sectional study, we included by multi-staged cluster random sampling 1343 children from high (HSES, n = 673) and low (LSES, n = 670) socioeconomic status schools in Douala. Parent/child demographic data were collected, and children's anthropometric parameters were measured using validated methods. The World Health Organization body mass index-for-age reference curves were used. RESULTS: The prevalence of overweight/obesity was 12.5% (13.2% in girls, 11.8% in boys). The risk of overweight/obesity was 2.40 (95% CI 1.70, 3.40) higher in HSES children compared to LSES after adjusting for age and gender. However this association was attenuated to 1.18 (95% CI 0.59, 2.35) once adjustment had been made for a range of potential confounders. CONCLUSIONS: Overweight/obesity is relatively common in sub-Saharan African children and prevalence is associated with HSES. However, this association may be mediated by sweet drink consumption, passive means of travel to school and not doing sport at school. We suggest that these potentially modifiable behaviors may be effective targets for obesity prevention. Further studies should specifically focus on unhealthy behaviors that mediate overweight/obesity as well as other non communicable diseases in children.

Sero-prevalence and Correlates of Hepatitis B and C Co-infection Among HIV-infected Individuals in Two Regional Hospitals in Cameroon.

BACKGROUND: Liver disease related to Hepatitis B (HBV) and C (HCV) infection has become a major cause of morbidity and mortality in HIV/AIDS patients. Data on the prevalence of HBV and HCV in Cameroon remains inconclusive. OBJECTIVE: We aimed to determine the sero-prevalence and correlates of Hepatitis markers in HIV/AIDS patients in two Regional Hospitals. METHODS: A cross-sectional study carried out from December 2014 to March 2015. HIV/AIDS patients aged 21 were included and above, receiving care at HIV treatment centres. Data was collected using a structured questionnaire. Blood samples were collected to screen for Hepatitis with HBsAg and anti HCV antibody rapid immunochromatographic test kits. Correlates of hepatitis were investigated by logistic regression. STATA was used for data analysis. RESULTS: We included 833 HIV/AIDS patients,78.8% (657) were female. Mean age was 44(SD 11) years. Prevalence of Hepatitis in general (total of two viral markers tested) was 8.9% (74/833), with 6.1% for HBsAg and 2.8% for Anti-HCV antibodies. From multivariate analysis, the likelihood of having hepatitis was independently increased by a history of surgical interventions [OR: 1.82(1.06-3.14)], and of sexually transmitted infections [OR: 2.20(1.04-4.67)]. CONCLUSION: Almost one in ten participants with HIV/AIDS attending the BRH and LRH tested positive for either HBsAg or anti HCV antibodies. Screening for HBV and HCV should therefore be integrated to the existing guidelines in Cameroon as it can influence management. More studies are needed to evaluate the extent of liver disease and magnitude of HIV suppression in hepatitis and HIV coinfection in this setting.

[Incidence of strokes in HIV-positive patients treated with long term antiretroviral treatment]. / Incidence des accidents vasculaires cérébraux chez les patients VIH positifs sous traitement antirétroviral au long court.

INTRODUCTION: With the introduction of triple therapy regimen in 1996, the morbidity and mortality associated with HIV infection decreased significantly. Concomitantly with this clinical success, several metabolic changes including diabetes, arterial hypertension, dyslipidemia and lipodystrophy were observed, being associated with the risk of stroke. This study aims to determine the incidence of strokes in HIV-positive patients treated with long term antiretroviral treatment. METHODS: This was a retrospective cohort study of HIV-positive adult patients receiving long term antiretroviral treatment for at least 12 months. It was conducted at the Approved Treatment Centres of Douala General Hospital (HGD); data collection spanned a 10-year period from May 2001 to April 2010. Patients were treated according to Cameroon national treatment guidelines. The Kaplan-Meyer method was used to determine the time of stroke onset. The Khi-2 test was used to investigate the association between two qualitative variables. The statistical significance level was set at 0.05. RESULTS: 407 patients were included in the study, 62.4% were female, the average age was 40.1 ± 9.9 years. The incidence of strokes was 1.7% over 72 months follow up with no significant difference between women and men (P = 0.76). The incidence rate was calculated to be 0.3 per 100 person years. 85.7% of cases had an ischemic stroke. The mean time from stroke onset was 33.4 months. Factors associated with stroke occurrence were: patients who underwent treatment at WHO Clinical Stage III and IV and with CD4 count> 100/mm3at the start of antiretroviral therapy. CONCLUSION: The incidence of stroke in HIV-positive patients treated with long term antiretroviral therapy is similar to that previously reported but these strokes occur at an early age and justify increased clinical monitoring. A prospective study involving a control population is needed.

Antiretroviral therapy in public and private routine health care clinics in Cameroon: lessons from the Douala antiretroviral (DARVIR) initiative.

A review of the hospital charts for 788 patients treated in 19 public and private clinics in Cameroon showed that clinical follow-up visits, biologic follow-up visits, and drug supply were irregular and that many patients interrupted treatment. Virological and immunologic effectiveness of therapy was as expected in patients for whom results were available.

Comparison of the clinical profile of Parkinson's disease between Spanish and Cameroonian cohorts.

BACKGROUND: There are limited data in terms of the clinical profile of Parkinson's disease in sub-Saharan African patients. OBJECTIVE: To compare the clinical profile and access to standard antiparkinsonian therapies of a Cameroonian cohort of patients with an age, sex, and disease duration-matched Spanish cohort (Longitudinal Study of Parkinson's disease, ELEP). METHODS: Observational, cross-sectional design. Demographic data were collected and the following ELEP assessments were applied: Scales for Outcomes in Parkinson's disease (SCOPA) Motor, Autonomic, Cognition, Sleep and Psychosocial; Hoehn and Yahr staging; modified Parkinson Psychosis Rating Scale; Cumulative Illness Rating Scale-Geriatrics; Hospital Anxiety and Depression Scale; pain and fatigue visual analog scales; Zarit, and EuroQoL. RESULTS: 74 patients with idiopathic Parkinson's disease were included (37 from each country) with a mean age of 64.4±10.5 years old, 70.3% males, and mean disease duration of 5.6±5.9 years. Compared to the Spanish cohort, Cameroonians were intermittently treated, less frequently received dopaminergic agonists (p<0.001), had a trend for taking lower doses of levodopa (p=0.06), and were more frequently on anticholinergics (p<0.0005). Cameroonians were more severely impaired in terms of motor (Hoehn Yahr stage, p=0.03; SCOPA-Motor, p<0.001), cognitive status (p<0.001), anxiety and depression (p<0.001), psychosis (p=0.008), somnolence, fatigue and pain (p<0.001, respectively), caregiver burden (p<0.0001), and quality of life (p=0.002). Instead, autonomic, comorbidity, and nocturnal sleep problems were similarly found. CONCLUSIONS: Limited and intermittent access to dopaminergic drugs has a negative impact on motor symptoms, nonmotor symptoms and quality of life in patients with Parkinson's disease and their caregivers.
