RESUMO

This study aimed to compare viral suppression (VS) between children, adolescents, and adults in the frame of transition to dolutegravir (DTG)-based antiretroviral therapy (ART) in the Cameroonian context. A comparative cross-sectional study was conducted from January 2021 through May 2022 amongst ART-experienced patients received at the Chantal BIYA International Reference Centre in Yaounde-Cameroon, for viral load (VL) monitoring. VS was defined as VL < 1000 copies/mL and viral undetectability as VL < 50 copies/mL. Chi-square and multivariate binary logistic regression models were used to identify factors associated with VS. Data were analyzed using SPSS v.20.0 (SPSS Inc., Chicago, Illinois), with P < .05 considered significant. A total of 9034 patients (72.2% females) were enrolled. In all, there were 8585 (95.0%) adults, 227 (2.5%) adolescents, and 222 (2.5%) children; 1627 (18.0%) were on non-nucleoside reverse transcriptase-based, 290 (3.2%) on PI-based, and 7117 (78.8%) on DTG-based ART. Of those on DTG-based ART, only 82 (1.2%) were children, 138 (1.9%) adolescents, and 6897 (96.9%) adults. Median (interquartile range) duration on ART was 24 (12-72) months (24 months on Tenofovir + Lamivudine + Dolutegravir [TLD], 36 months on other first lines, and 84 months on protease inhibitors boosted with ritonavir-based regimens). Overall, VS was 89.8% (95% confidence interval: 89.2-90.5) and viral undetectability was 75.7% (95% confidence interval: 74.8-76.7). Based on ART regimen, VS on Non-nucleoside reverse transcriptase-based, protease inhibitors boosted with ritonavir-based, and DTG-based therapy was respectively 86.4%, 59.7%, and 91.8%, P < .0001. Based on ART duration, VS was respectively 51.7% (≤24 months) versus 48.3% (≥25 months), P < .0001. By gender, VS was 90.9% (5929) in females versus 87.0% (2183) in males, P < .0001; by age-range, VS moved from 64.8% (144) in children, 74.4% (169) adolescents, to 90.8% (7799) adults, P < .0001. Following multivariate analysis, VS was associated with adulthood, female gender, TLD regimens, and combination antiretroviral therapy duration > 24 months (P < .05). In Cameroon, ART response indicates encouraging rates of VS (about 9/10) and viral undetectability (about 3/4), driven essentially by access to TLD based regimens. However, ART response was very poor in children, underscoring the need for scaling-up pediatric DTG-based regimens.

RESUMO

Objective: To evaluate the risk of prematurity in Cameroonian children born after in vitro Fertilisation. Design: A retrospective cohort study. Setting: Conducted at the pediatric department of the Hospital Center for Research and Application in Endoscopic Surgery and Human Reproduction (HCRAESHR) in Yaoundé over eight months. Participants: Every newborn born after in vitro fertilisation (exposed group) and those born after spontaneous conception (non-exposed group) from a singleton pregnancy were included. Multiple pregnancies were excluded. One hundred newborns per group were recruited and matched according to the mode of delivery. Interventions: The main outcome measure was prematurity at birth. Data were collected from the medical records of the newborns and reported on individual questionnaires. The t Student test was used to assess the differences in gestational age between the two groups. The generalised linear model using binomial probability distribution was used for multivariate analysis to determine prematurity risk factors. All results with a p-value ≤ 0.05 were considered statistically significant. Results: Prematurity was significantly predominant in the exposed group (22% and 5%, respectively, p=0.002) compared to the non-exposed group. The risk of prematurity in the exposed group was 4.4 times higher than in the non-exposed group. After controlling for confounders (the maternal age, the sex of the baby, and maternal hypertension), this risk increased significantly from 4.4 to 7.67 (p=0.001). Conclusion: This study demonstrated the first evidence from our part of the world showing that in vitro fertilisation is an absolute risk of prematurity. Funding: None declared.

RESUMO

BACKGROUND: Procalcitonin is an inflammatory marker strongly associated with the presence of bacterial infection. It has been considered raised in severe malaria infection as opposed to uncomplicated malaria. There are suggestions that it may be raised only when there is concomitant unnoticeable bacterial infection during a malaria crisis. We aimed to assess the difference in plasma procalcitonin levels between children affected by severe and uncomplicated malaria. METHODS: We assessed plasma procalcitonin levels in 83 children diagnosed with malaria with no clinical and biological evidence of concomitant bacterial infection. Severity of malaria was established using WHO guidelines. Procalcitonin was determined using the ELISA method. Non-parametric Mann-Whitney U test was used to compare medians across the 2 groups. Statistical significance was set for all p values < 0.05. RESULTS: Of the 83 participants, 28 had uncomplicated malaria, and 55 had severe malaria. PCT levels were obtained in 24 and 40 subjects of each group, respectively, and were similar in both groups; [2.76 (2.52-2.93) vs 2.74 (2.52-2.98) ng/ml, p = 0.916]. The parasite density was lower in the uncomplicated malaria group than in the severe malaria group, but not statistically significant; [22,192 (9110-44 654) vs 31 684 (13 960-73 500) parasites/µl, p = 0.178]. There was no correlation between the parasite density in the general study population and PCT levels (r = 0.072, p = 0.572). CONCLUSION: In the absence of overt bacterial infection, procalcitonin levels are not different between children affected with uncomplicated malaria and those with severe malaria. Therefore, bacterial infection should be thoroughly checked for in children with raised serum procalcitonin diagnosed with severe malaria.

RESUMO

INTRODUCTION: non-adherence to antiretroviral therapy (ART) constitutes the main cause of therapeutic failure among HIV-infected adolescents, especially in the aged group 15 to 19 years. We aimed to determine factors associated with this non-adherence in this specific population. METHODS: we conducted a cross-sectional study at the Mother and Child Center in Yaounde from August to October 2018. Delayed clinic appointment was referred to as defaulters. Non-adherence was measured during the 3 days preceding inclusion by self-reported method following quantitative (missing dosage of ART), qualitative (ART taken with a delay of more than 2 hours) and combined measure. A threshold of non-adherence > 20% was considered high, with p<0.05 statistically significant. RESULTS: overall, 195 out of 251 (77.7%) eligible adolescents were included, of which 56.9% were girls (sex-ratio = 4/3). The mean age was 16.8 ± 1.5 years. The rate of defaulters was 21.0%. Following quantitative approach, 33.8% were non-adherent. Using combined approach, we had 41.0%. This non-adherence was associated with duration on ART > 5 years (adjusted Odds Ratio [aOR]: 2.33;95% Confidence Interval [CI]: 1.08-5.00; p:0.030), defaulters (aOR: 2.56;95% CI: 1.12-5.82; p:0.025) and HIV Viral Load (VL) ≥ 40 copies/ml (aOR: 0.42; 95% CI: 0.21-0.83; p:0.013). CONCLUSION: at this reference pediatric center, 4 out of 10 adolescents aged 15-19 years on ART are non-adherent, driven by missing dosage of drug intake. Strategies for enhanced adherence for late age adolescents are therefore warranted, by prioritizing interventions on defaulters and duration on ART > 5 years.

RESUMO

Dengue virus (DENV) causes a spectrum of diseases ranging from asymptomatic, mild febrile to a life-threatening illness: dengue hemorrhagic fever. The main clinical symptom of dengue is fever, similar to that of malaria. The prevalence of dengue virus infection, alone or in association with other endemic infectious diseases in children in Cameroon is unknown. The aim of this study was to determine the prevalence of dengue, malaria and HIV in children presenting with fever and associated risk factors. Dengue overall prevalence was 20.2%, Malaria cases were 52.7% and HIV cases represented 12.6%. The prevalence of dengue-HIV co-infection was 6.0% and that of Malaria-dengue co-infection was 19.5%. Triple infection prevalence was 4.3%. Dengue virus infection is present in children and HIV-Dengue or Dengue- Malaria co-infections are common. Dengue peak prevalence was between August and October. Sex and age were not associated with dengue and dengue co-infections. However, malaria as well as HIV were significantly associated with dengue (P = 0.001 and 0.028 respectively). The diagnosis of dengue and Malaria should be carried out routinely for better management of fever.

RESUMO

Complementary foods in Africa are often poor sources of bioavailable iron. We assessed the efficacy of iron-fortified wheat-based infant cereal (IC) to reduce the risk of iron deficiency anemia in children aged 18-59 months in Cameroon. A 6-month double-blind, cluster-randomized controlled trial was conducted in 2017 among anemic (hemoglobin 7-11 g/dl) but otherwise healthy children. In conjunction with usual diet, children received two 50 g servings/day of a standard, micronutrient-fortified IC (providing 3.75 mg iron/serving; n = 106) or the same IC without iron fortification (n = 99). Anthropometric measurements, blood sampling, and systematic deworming were performed in all children at baseline (pre-intervention), 3, and 6 months. Mean hemoglobin, ferritin adjusted for C-reactive protein (CRP), serum iron, transferrin saturation, prevalence of anemia, iron deficiency, and iron deficiency anemia as well as anthropometrics were compared between the groups at baseline, 3, and 6 months. Compared to the control group, children consuming the iron-fortified IC had significantly higher baseline-adjusted mean hemoglobin (10.0 ± 1.8 vs. 9.7 ± 1.4 g/dl, respectively; p = .023), ferritin adjusted for CRP (16.1 ± 8.3 vs. 9.5 ± 7.5 µg/L, p < .001), serum iron (14.5 ± 3.9 vs. 11.2 ± 4.4 µg/dl; p < .001), and transferrin saturation (19.0 ± 17.4 vs. 10.7 ± 12.5%; p Ë‚ .001) at 6 months. The prevalence of anemia, iron deficiency, and iron deficiency anemia at 6 months decreased by a larger extent in the iron-fortified group versus controls (all p < .01). In addition, at 6 months, children in the iron-fortified group demonstrated higher weight-for-age z-scores (p = .016) compared to the control group. Wheat-based IC fortified with 7.5 mg ferrous fumarate administered daily for 6 months improved iron and nutritional status and decreased the prevalence of iron deficiency anemia in children aged 18-59 months in Salapoumbé, Cameroon.

RESUMO

BACKGROUND: Intestinal parasitic infections are among the most common communicable diseases worldwide, particularly in developing countries. Human immunodeficiency virus (HIV) causes dysregulation of the immune system through the depletion of CD4+ T lymphocytes which gives rise to opportunistic infections. METHODOLOGY: A cross-sectional study was conducted from January to October 2018. Stool and blood samples were collected from participants aged 1 to 19. Stool samples were analyzed for intestinal parasites. Blood samples were analyzed for HIV and CD4 + T cell counts. RESULTS: Out of 214 children enrolled, 119 (55.6%) were HIV infected and 95 (44.4%) were HIV non-infected. All infected children were on antiretroviral treatment (ART). The prevalence of intestinal parasites was 20.2% in HIV infected and 15.8% in non-infected children. Among the 119 HIV infected children, 33 (27.7%) of them had a CD4+ T cell count less than 500 cells/mm3, and amongst them 5.9% had CD4+ T cell count less than 200 cells/mm3. Among HIV infected children, Cryptosporidium spp. was frequently detected, 7/119 (5.9%), followed by Giardia lamblia 5/119 (4.2%) then Blastocystis hominis 3/119 (2.5%) and Entamoeba coli 3/119 (2.5%). Participants on ART and prophylactic co-trimoxazole for >10 years had little or no parasite infestation. CONCLUSIONS: Although ART treatment in combination with prophylactic co-trimoxazole reduces the risk of parasitic infection, 20.2% of HIV infected children harbored intestinal parasites including Cryptosporidium spp. Stool analysis may be routinely carried out in order to treat detected cases of opportunistic parasites and such improve more on the life quality of HIV infected children.

RESUMO

INTRODUCTION: HIV infection is characterized by changes in the composition and functions of gut microbiota. We carried out a study aiming at comparing the compositional changes of the digestive flora of HIV infected infants versus that of non infected infants in Cameroon. METHODS: A case-control study was carried out during which stool sample was collected from each participant after obtaining the proxy consent. Stools were cultured using aerobic, strict anaerobic, 10% CO2 and micro-aerophilic conditions and specific culture media and bacteria were identified biochemically. Fisher's exact test was used for data analyses. RESULTS: From the 80 infants enrolled for the study, 33 (41.3%) were HIV positive. A statistically significant difference was observed between the number of infected versus non infected infants harboring the following bacteria: Clostridium spp. (P=0.009); Enterococcus spp. (p<0.001); Klebsiella (p<0.001); Shigella (<0.001); Staphylococcus aureus (p=0.006) and Streptococcus spp. (P=0.015). Among infected infants, WHO-stage 3 and 4 infants harbored more opportunistic bacteria than stage 1 and stage 2 and Bacteriodes spp. population was depleted as the disease progresses, although not significantly. There was an imbalance in bacteria flora in HIV infected infants harboring qualitatively more bacteria including more opportunistic and pathogenic bacteria than in HIV non-infected infants. CONCLUSION: HIV infected infants presented a qualitatively different flora from HIV non infected infants. They habored more pathogenic bacteria Than non infected infants. Systematic stool culture could benefit for follow-up of HIV infected infants to reduce the risk of gastrointestinal disorders and thus the risk of high morbidity or high mortability.

RESUMO

BACKGROUND: Patient education is essential in management of type 1 diabetes (T1D). OBJECTIVE: To evaluate the short-term impact of patient education through WhatsApp on the knowledge of the disease and glycemic control of adolescents and young adults living with T1D in a resource-limited setting. METHODS: A double arm non-randomized clinical trial was carried out in two clinics for diabetes in Cameroon, over a period of 2 months. The intervention consisted in providing four sessions of patient education through WhatsApp to an intervention group compared to a control group with their classic follow-up. We evaluate their knowledge on diabetes, acute events, and glycemic control, before and after intervention. RESULTS: We recruited 54 patients of which 25 subjects and 29 controls. Median age was 19 (17-20) and 19 (17-21) years for the intervention and control group, respectively. There was a significant improvement of knowledge on diabetes in the intervention group from 13/20 to 16/20 (P < 0.01) after 2 months, compared to a slight decrease in control group (from 11.6/20 to 11.3/20 (P = 0.33). The mean proportion of acute complications decreased from 28% to 16% (P = 0.46) in the intervention group, and increased from 7% to 34%, P = 0.01 in the control group. There was no improvement in glycosylated hemoglobin level in both groups. CONCLUSION: Patient education through social network helped to improve knowledge on T1D and to reduce acute complications without an improvement of glycemic control after 2 months.

RESUMO

INTRODUCTION: Growth of children affected by Sickle Cell Disease (SCD) is not well described in sub-Saharan Africa despite the high prevalence of the disease. Few data are available in this context and on the issue using the World Health Organization growth norms. We therefore conduct the present study with the aim of describing the growth of affected children aged less than 5 years. We also assessed correlation of anthropometric parameters with disease severity criteria. METHODS: A cross-sectional study was conducted during a period of 8 months, at the Mother and Child Center of Yaoundé. The sample included 77 children with SCD aged 2 to 5 years old in steady state. Anthropometric measurements and socio-demographic data were collected and analyzed. All statistical tests were two-tailed with p<0.05 considered significant. RESULTS: Median age of study population was 3.67 years. Low weight, height and weight for height Z-scores (<-2SD) were observed in 4%, 4%, and 5% of children, respectively. Projection of these parameters were stackable on WHO curves. Regression analysis indicated an association of low height-for-age and of low Body Mass Index (BMI)-for-age with age. CONCLUSION: This study demonstrates unexpectedly lower mean Z-score for weight, height and weight for height than reported while using WHO norms.

RESUMO

With limited and low-genetic barrier drugs used for the prevention of mother-to-child transmission (PMTCT) of HIV in sub-Saharan Africa, vertically transmitted HIV-1 drug-resistance (HIVDR) is concerning and might prompt optimal pediatric strategies.The aim of this study was to ascertain HIVDR and viral-tropism in majority and minority populations among Cameroonian vertically infected children.A comparative analysis among 18 HIV-infected children (7 from PMTCT-exposed mothers and 11 from mothers without PMTCT-exposure) was performed. HIVDR and HIV-1 co-receptor usage was evaluated by analyzing sequences obtained by both Sanger sequencing and ultra-deep 454-pyrosequencing (UDPS), set at 1% threshold.Overall, median (interquartile range) age, viremia, and CD4 count were 6 (4-10) years, 5.5 (4.9-6.0) log10 copies/mL, and 526 (282-645) cells/mm, respectively. All children had wild-type viruses through both Sanger sequencing and UDPS, except for 1 PMTCT-exposed infant harboring minority K103N (8.31%), born to a mother exposed to AZT+3TC+NVP. X4-tropic viruses were found in 5 of 15 (33.3%) children (including 2 cases detected only by UDPS). Rate of X4-tropic viruses was 0% (0/6) below 5 years (also as minority species), and became relatively high above 5 years (55.6% [5/9], P = .040. X4-tropic viruses were higher with CD4 ≤15% (4/9 [44.4%]) versus CD4 >15% (1/6 [16.7%], P = .580); similarly for CD4 ≤200 (3/4 [75%]) versus CD4 >200 (2/11 [18.2%] cells/mm, P = .077.NGS has the ability of excluding NRTI- and NNRTI-mutations as minority species in all but 1 children, thus supporting the safe use of these drug-classes in those without such mutations, henceforth sparing ritonavir-boosted protease inhibitors or integrase inhibitors for the few remaining cases. In children under five years, X4-tropic variants would be rare, suggesting vertical-transmission with CCR5-tropic viruses and possible maraviroc usage at younger ages.

RESUMO

BACKGROUND: Although sickle cell disease (SCD) children are highly susceptible to bacterial infections (BIs), there is a dreadful lack of data related to the burden and spectrum of BIs in sub-Saharan Africa (SSA), the highest affected region with SCD. This study aimed to determine the burden and spectrum of BIs among SCD children hospitalized in a pediatric reference hospital in Cameroon, a SSA country. METHODS: We conducted a retrospective analysis of records of children hospitalized from November 2012 to August 2015 in the SCD unit of the Mother and Child Centre of the Chantal Biya Foundation, Cameroon. We enrolled all known SCD children aged 15 years or less, hospitalized for a suspicion of BI and who presented a positive culture of a body specimen. RESULTS: A total of 987 SCD children were hospitalized during the study period. Cultures were positive for 96 patients (9.7%) among whom 60.4% males. Ages ranged from 6 to 192 months with a median of 53 (Interquartile range (IQR) 21-101) months. For children no more covered by the Expanded Programme on Immunization, only 13 (18.8%) had received the Pneumo 23® and Meningo A&C® antigens, and 12 (17.4%), the Typhim vi® and the Haemophilus influenzae type b antigens; 58 children (84.1%) had received no vaccine. The specimen yielding positive cultures were: blood (70.7%), urine (13.1%), pus (9.1%), synovial fluid (4.1%), cerebrospinal fluid (2.0%), and bone fragment (1.0%). The different types of infection included: urinary tract infections (13.5%), myositis (8.3%), arthritis (6.3%), osteomyelitis (4.2%), and meningitis (2.1%); the site of infection was unidentified in 65.6% of cases. The main bacteria included: Salmonella sp. (28.1%), Staphylococcus sp. (18.8%), Klebsiella pneumoniae (17.7%), Escherichia coli (10.4%), Enterobacter sp. (5.2%), Acinetobacter sp. (4.2%), Streptococcus sp. (4.2%) and Serratia sp. (4.2%). CONCLUSION: This retrospective analysis revealed 9.7% cases of BIs, mainly caused by Salmonella sp. (28.1%), Staphylococcus sp. (18.8%), Klebsiella pneumoniae (17.7%), and Escherichia coli (10.4%).

RESUMO

BACKGROUND: Although sub-Saharan Africa (SSA) is particularly affected by sickle cell disease (SCD), there is dearth of research on this topic in the region, specifically targeting the magnitude of SCD-related complications. We therefore conducted this study to determine the burden of acute chest syndrome (ACS) and describe its clinical and therapeutic aspects among SCD children in Cameroon, a SSA country. METHODS: This was a retrospective study carried-out from September 2013 to June 2014 at the SCD unit of the Mother and Child Centre of the Chantal Biya Foundation, a pediatric reference centre in Yaoundé, Cameroon. We enrolled all SCD children with confirmed diagnosis of ACS, and recorded their clinical presentation at admission along with their evolution during hospitalization. RESULTS: Twenty one cases of ACS were identified during the study period, from 338 hospitalizations of children with SCD. Ages ranged from 11 months to 16 years with a mean (standard deviation) of 5.5 (3.4) years, and a male/female sex ratio of 3.2/1. We noticed relatively low levels of HbF, from 6.4 to 21.9% with a mean of 14.6% (6.0%). The three main symptoms at admission were fever (90.5%), cough (81%) and chest pains (28.6%). Two patients (9.5%) developed ACS 2 days after admission. The mean values of leukocytes, neutrophils, serum CRP, serum LDH and hemoglobin were respectively 32479.4 (17862.3)/mm(3), 23476 (11543.7)/mm(3), 228.2 (132.6) mg/l, 3452.3 (2916.3) IU/l and 6.5 (1.2) g/dl. The main localizations of radiological alveolar consolidations were the lower lobes (90.5%). Treatment associated broad-spectrum antibiotics (100%), hydration (100%), analgesics (43.2%), whole blood transfusion (66.7%), and oxygen supplementation (33.3%). Blood transfusion significantly improved hemoglobin level (p = 0.039). The duration of hospitalization, the mean of which was 6.8 (3.1) days, was influenced by none of the tested variables (all p values > 0.05). CONCLUSION: ACS is frequent among SCD children in our milieu. Its etiologies seem to be multifactorial. Patients' parents should be educated to recognize early signs and symptoms of the disease, and consult rapidly. Additionally, clinicians must be trained to diagnose ACS, and manage it promptly and efficiently to avoid its related catastrophic consequences.

RESUMO

Congenital hypothyroidism is a main congenital endocrine disorder, affecting 1 in 4000 births. It is not well described in sub-Saharan countries, and to draw attention to that issue, we decided to describe affected pediatric patients. We retrospectively analyzed the records of eight patients over a period of 6 years. We analyzed clinical sings of hypothyroidism and psychomotor development; hormonal assays and thyroid ultrasound were performed. We included four boys and four girls aged from 3 to 84 months at diagnosis with a median thyroid-stimulating hormone (TSH) level of 156.5 mUI/L. All except one present with a moderate psychomotor delay. Other clinical signs were classical for hypothyroidism. Thyroid ultrasound performed showed a goiter in half of patients, a normal gland in three of them and a hypoplasic gland in the last one, consonant with dyshormonogenesis. We therefore concluded that dyshormonogenesis seems to be more frequent in our context, and this raised the issue of neonatal screening of hypothyroidism in Africa.

RESUMO

BACKGROUND: We investigated HIV testing practices at baseline among pregnant women and their partners within a multicountry randomized trial aiming to evaluate the effect of enhanced prenatal posttest HIV counseling on men's involvement. METHODS: In Yaoundé, Cameroon, 484 pregnant women with stable partners were recruited on their first antenatal care visit. We analyzed the coverage of previous HIV testing among women and their partners and looked for the factors associated with previous HIV testing, using multivariable logistic regression. RESULTS: Among 476 pregnant women who completed the baseline questionnaire, 408 (85.7%) reported having been tested for HIV already once in their life, 48.3% of them during a previous pregnancy. Women previously tested for HIV were more likely to be in a stable relationship for >5 years than those never tested (P < 0.001). In multivariable analysis, tested women were more likely to be aged between 25 and 30 years compared with women <20 years [odds ratio (OR) 5.5, 95% confidence interval (CI): 1.4 to 22.1], to be able to say whether they felt at risk for HIV infection (OR 2.1, CI: 1.1 to 3.9), and to have ever discussed about HIV with their partner (OR 2.7, CI: 1.1 to 6.4). Most women (85.1%) reported that their partner had already been tested for HIV. Reasons for partner HIV testing were related to self-motivation (30.0%) and clinical symptoms (12.7%). CONCLUSIONS: Strategies aiming at improving knowledge and couple communication about HIV risks need to be considered to address the remaining barriers to HIV testing and contribute to a couple approach to HIV prevention.
