BackgroundThe introduction of anti-retroviral treatment (ART) has significantly reduced mortality and morbidity associated with HIV/AIDS. While treatment at early stages of the disease is related to a better prognosis, late presentation (LP) to care is harmful to the infected person, the society and is more costly. We aimed to describe late presentation to HIV care, its associated factors and consequences in patients followed up in a tertiary hospital in Cameroon.MethodsWe retrospectively assessed patients’ files between 1996 and 2014 at the Douala general hospital (DGH) HIV treatment centre. Late presentation (LP) to HIV care was defined as a CD4+ T cell count< 350 cells/mm3 or advanced clinical stages of the disease (WHO stages 3/4) at first presentation for care. We used logistic regression to study factors associated with late presentation and assessed occurrence of opportunistic infections and mortality at 3, 6 and 12 months after presentation to care.ResultsOf 1866 files studied, mean age was 40 (SD: 10) years, median CD4+ T cell count was 147 (IQR: 63–270) cells/mm3, 58.2% were at HIV clinical stages 3 and 4. The prevalence of late presentation to HIV care was 89.7% (95% CI: 88.2–91.0%) and remained above 80% from 1996 to 2014. Circumstances of diagnosis: prevention of mother to child transmission program/blood donation (OR = 0.16, 95% CI 0.10–0.29), having a positive partner (OR = 0.16, 95%CI = 0.10–0.26), and routine screening (OR = 0.13, 95%CI = 0.10–0.19) reduced the odds of presenting late compared to clinical suspicion. Students had lower odds of presenting late compared to people who had an employment (OR = 0.50, 95%CI = 0.26–0.98). Calendar time OR = 1.64, 95% CI = 1.08–2.48 for ≥2010 vs. < 2005) increased the odds of late presentation. Mortality and opportunistic infections prevalence remained significantly higher in late presenters at 3, 6 and 12 months than in early presenters.ConclusionLate presentation to HIV care is very high at the DGH and is related to poor outcome. More screening and sensitization campaigns should be carried out in the population to diagnose the disease at an earlier stage.

Background: Point-of-care haemoglobin meters are attractive solutions to improve timely diagnosis of anaemia in resource-limited settings. However, concerns regarding the accuracy of these meters may affect their adoption. The accuracy of two hand-held point-of-care haemoglobin meters was evaluated against reference full blood count analyser. Methods: This was a hospital-based cross-sectional study conducted at the Douala General hospital, Cameroon. Two handheld haemoglobin meters were assessed: Urit12® (URIT Medical Electronics Co.,Ltd. Guangxi, China) and MissionHb®(ACON Laboratories, Inc., San Diego, USA); against a reference standard CELL-DYN RUBY® (ABBOTT DIAGNOSTICS, Illinois, USA). The Pearson's correlation and Bland-Altman agreement were used to assess the technical accuracy of the meters. Clinical accuracy was evaluated using total error allowable and area under the Receiver Operating Curve. Finally, their agreement with the reference in diagnosing anaemia was assessed using the kappa statistic. Results: A total of 228 participants were included in the study. The mean haemoglobin values of both haemoglobin meters (MissionHb®: 11.6 ± 2.5 g/dl; Urit12®: 10.9 ± 2.7 g/dl) were significantly higher than the reference value (10.5 ± 2.5 g/dl), p < 0.001 for both meters. Both haemoglobin meters had good correlation with the reference analyser (r = 0.89 and r = 0.90 for Urit12® and MissionHb® respectively) and good agreement on the Bland-Altman plots. However, the MissionHb® meter did not meet the clinical accuracy requirements (p < 0.001). Even though both meters were excellent at identifying the presence of anemia (MissionHb®-AUC = 0.9161, Urit 12®-AUC = 0.9009), they, however, both had weak agreement with the reference analyser in diagnosing the severity of anaemia (K = 0.39 for MissionHb®, p < 0.001 and K = 0.54 for Urit12®, p < 0.001). Conclusion: Although both devices showed technical accuracy with a positive correlation with the reference analyser and were able to accurately diagnose the presence of anemia, both meters however, had sub-optimal agreement with the reference analyser in diagnosing the degree of severity of anaemia among our participants.

BackgroundSickle Cell Disease (SCD) is associated with chronic multisystem complications that significantly influence the quality of life (QOL) of patients early in their life. Although sub-Saharan Africa bears 75% of the global burden of SCD, there is a paucity of data on these complications and their effects on the QOL. We aimed to record these chronic complications, to estimate the QOL, and to identify the corresponding risk factors in patients with SCD receiving care in three hospitals in Cameroon.MethodsIn this cross-sectional study, a questionnaire was used to collect data from consecutive consenting patients. Information recorded included data on the yearly frequency of painful crisis, the types of SCD, and the occurrence of chronic complications. A 36-Item Short Form (SF-36) standard questionnaire that examines the level of physical and mental well-being, was administered to all eligible participants. Data were analyzed with STATA® software.ResultsOf 175 participants included, 93 (53.1%) were female and 111 (aged ≥14 years) were eligible for QOL assessment. The median (interquartile range, IQR) age at diagnosis was 4.0 (2.0-8.0) years and the median (IQR) number of yearly painful crisis was 3.0 (1.0–7.0). The most frequent chronic complications reported were: nocturnal enuresis, chronic leg ulcers, osteomyelitis and priapism (30.9%, 24.6%, 19.4%, and 18.3% respectively). The prevalence of stroke and avascular necrosis of the hip were 8.0% and 13.1% respectively. The median (IQR) physical and mental scores were 47.3 (43.9–58.5) and 41.0 (38.8–44.6) respectively. Age and chronic complications such as stroke and avascular necrosis were independently associated with poor QOL.ConclusionsIn this population of patients living with SCD, chronic complications are frequent and their QOL is consequently poor. Our results highlight the need for national guidelines for SCD control, which should include new-born screening programs and strategies to prevent chronic complications.Electronic supplementary materialThe online version of this article (doi:10.1186/s12878-017-0079-7) contains supplementary material, which is available to authorized users.

Background: With easy accessibility to combination Antiretroviral Therapy (cART), mortality amongst hospitalized HIV/AIDS patients needs to be described. Objective: We aimed at determining the trends, causes and factors associated with in-hospital mortality amongst HIV/AIDS patients in the Douala General Hospital. Methods: We retrospectively reviewed hospitalisation records of HIV/AIDS patients hospitalized in the medical wards of the DGH from 2007 to 2015. Four cause-of-death categories were defined: 1. Communicable conditions and AIDS-defining malignancies, 2. Chronic non-communicable conditions and non-AIDS defining malignancies’, 3. Other non-communicable conditions and 4. Unknown conditions. Logistic regression was used to determine factors associated mortality. Results: We analyzed 891 eligible files. The mean age was 43 (standard deviation (SD): 10) years and median length of hospital stay was 9 (interquatile range (IQR)4 - 15) days. The overall all-cause mortality was 23.5% (95% CI: 20.8% - 26.4%). The category - communicable conditions and AIDS defining malignancies represented 79.9%, of deaths and this remained constant for each year during the study period. Tuberculosis was the most common specific cause of death (23.9%). Patients who had two (OR=2.35, 95%CI: 1.35 - 4.06) and more than two (OR=4.23, 95%CI: 1.62 – 11.12) opportunistic infections, a haemoglobin level less than 10g/l (OR=2.38, 95%CI: 1.58 - 3.59) had increased odds of dying. Conclusion: In-hospital mortality is high amongst HIV/AIDS patients at the Douala general hospital. The category - communicable conditions and AIDS defining malignancies - is still the main underlying cause of death. We hope that our findings will help to develop interventions aimed at reducing in-hospital mortality.

A total of 126 patients were included in the study-65 girls and 61 boys. The mean age of the subjects was 8 ± 4 years (ranging from three to sixteen years). The most represented age group was that from 3-4 years of age. Most of the participants were from the Central Region (46%). All of the subjects were homozygous for hemoglobin SS. Subjects with yearly frequency of three vaso-occlusive crises represented 42.9% of the sample. 57.9% of the patients had been polytransfused within the past 3 years (>2 transfusions). Up to 45.2% of the patients had been hospitalized within the past year.
