HIV Wasting Syndrome in a Nigerian Failing Antiretroviral Therapy: A Case Report and Review of the Literature

The HIV wasting syndrome represented the face of HIV/AIDS before the advent of highly active antiretroviral therapy (HAART). Although the incidence of wasting has declined since the introduction of HAART, weight loss remains common in patients receiving HAART, especially in the setting of a failing HAART regimen. As we are not aware of any previous reports from Nigeria, we report a case of the classical wasting syndrome in a Nigerian female who had both virological and immunological HAART failure due to poor adherence. The influence of a failing HAART regimen, socioeconomic status, and other clinical variables in the wasting syndrome are discussed

Disseminated infections due to Immune Reconstitution Inflammatory Syndrome after Highly Active Antiretroviral Therapy-Report of 3 cases from Nigeria

Immune Reconstitution Inflammatory Syndromes (IRIS) are exaggerated pathological inflammatory reactions occurring after initiation of highly active antiretroviral therapy (HAART) due to exuberant immune responses to occult or apparent opportunistic infections or cancers. In view of paucity of studies from Nigeria, we report 3 cases of IRIS presenting as disseminated infections in HIV-1 infected patients initiating HAART. The first case was a previously healthy female who developed disseminated tuberculosis after 4 weeks of regular HAART. Her HAART regimen was continued and she improved after commencement of anti-tuberculosis drugs, with evidence of progressive increase in CD4 cell count. The second case was a HAART-experienced female who stopped her drugs for 4months. Two months after recommencement of her previous HAART regimen, she developed features of disseminated herpes zoster infection, despite evidence of decrease in viral load by 95%. HAART was continued and she recovered completely after receiving valaciclovir tablets and antibiotics. The third patient was a female student who was commenced HAART on account of chronic cough and weight loss. Three months after regular HAART, she developed features of disseminated Kaposi's sarcoma involving the skin, oropharynx and lungs, despite evidence of 42% increase in CD4 cell count. Unfortunately, she rapidly deteriorated and died during the course of management. Clinicians should be alert to the possibility of IRIS in HIV-infected patients initiated or re-initiated on HAART. There is need for future prospective studies determining risk factors for IRIS in HIV-infected patients from Nigeria

Determinants of first‐ever stroke severity in West Africans: evidence from the SIREN study

Background: Baseline stroke severity is probably partly responsible for poor stroke outcomes in sub-Saharan Africa. However, there is a paucity of information on determinants of stroke severity among indigenous Africans. We sought to identify the factors associated with stroke severity among West Africans in the SIREN (Stroke Investigative Research and Educational Networks) study. Methods and Results: Stroke was diagnosed clinically and confirmed with brain neuroimaging. Severe stroke was defined as a Stroke Levity Scale score of ≤5. A multivariate logistic regression model was constructed to identify factors associated with stroke severity at 95% CI and a nominal cutoff of 5% type 1 error. A total of 3660 stroke cases were included. Overall, 50.7%% had severe stroke, including 47.6% of all ischemic strokes and 56.1% of intracerebral hemorrhage. Factors independently associated with severe stroke were meat consumption (adjusted odds ratio [aOR], 1.97 [95% CI, 1.43-2.73]), low vegetable consumption (aOR, 2.45 [95% CI, 1.93-3.12]), and lesion volume, with an aOR of 1.67 (95% CI, 1.03-2.72) for lesion volume of 10 to 30 cm3 and aOR of 3.88 (95% CI, 1.93-7.81) for lesion volume \u3e30 cm3. Severe ischemic stroke was independently associated with total anterior circulation infarction (aOR, 3.1 [95% CI, 1.5-6.9]), posterior circulation infarction (aOR, 2.2 [95% CI, 1.1-4.2]), and partial anterior circulation infarction (aOR, 2.0 [95% CI, 1.2-3.3]) compared with lacunar stroke. Increasing age (aOR, 2.6 [95% CI, 1.3-5.2]) and lesion volume \u3e30 cm3 (aOR, 6.2 [95% CI, 2.0-19.3]) were independently associated with severe intracerebral hemorrhage. Conclusions: Severe stroke is common among indigenous West Africans, where modifiable dietary factors are independently associated with it. These factors could be targeted to reduce the burden of severe stroke

Psychometric validity of the distress thermometer and problem check list in ART-na\uefve HIV infected patients in Northern Nigeria

Background: HIV diagnosis comes with a lot of worry and distress. Ability to objectively estimate this distress by non-psychiatrist will enhance early detection of psychological distress for intervention. Objectives: To investigate the validity of the Distress Thermometer (DT) and its problem checklist in achieving early detection of mental distress among ART-na\uefve HIV infected patient. Materials and Methods: A total of 90 ART-na\uefve HIV infected patients completed the DT and its problem check list, Hospital Anxiety Depression Scale (HADS), Oslo Social Support Scale and the 14-item Resilience Scale. Results: The DT was positively correlated with all the measures of distress and reversely correlated with all the positive wellness in this study. The correlations were only significant for the negative measures of psychological wellness. The internal consistency of the DT\u2019s problem list overall and sub-categories were within acceptable range (i.e. \u3b1 > 0.50). The Receiver Operating Characteristic (ROC) curves and Area Under the Curves (AUC) analysis were significant and found the DT and Problem List to respectively differentiate between cases of distress, anxiety and depression. The DT\u2019s cut-off was >5.0 with AUC range (0.754 \u2013 0.709); sensitivity range (81.0% \u2013 70.4%); specificity range (68.3% \u2013 65.2%) for distress, anxiety and depression as determined by HADS. And the Problem List cut-off was >6.0 with AUC range (0.854 \u2013 0.821); sensitivity range (90.5% - 85.7%); specificity range (68.3% - 65.2%) for distress, anxiety and depression as measured by HADS. Conclusion: The DT and Problem List were found to be valid measures of distress in ART-na\uefve HIV infected patients

Addressing antimicrobial resistance in Nigerian hospitals : exploring physicians prescribing behavior, knowledge, and perception of antimicrobial resistance and stewardship programs

Introduction: We assessed the knowledge of, attitude toward antimicrobial resistance (AMR) and practice of antimicrobial stewardship (AMS) among physicians in Nigeria to provide future guidance to the Nigerian National Action Plan for AMR. Methods: A descriptive cross-sectional questionnaire-based study explored the physicians’ self-reported practice of antibiotic prescribing, knowledge, attitude, and practice of AMR and components of ASPs. Results: The majority (217; 67.2%) of respondents prescribed antibiotics daily in their clinical practice AMR was recognized as a global and local problem by 308 (95.4%) and 262 (81.1%) respondents, respectively. Only 91 (28.2%) of respondents have ever heard of antibiotic stewardship. The median AMR knowledge score was 40 (19–45)out of 45while that for ASP was 46.0(32–57) out of 60. There was significant statistical difference between the ASP median scores among the medical specialties category (P value <0.0001) More respondents had good knowledge of AMR than ASPs (82.7% versus 36.5%; p < 0.0001). Conclusion: Respondents in this study were more knowledgeable about AMR than AMS and its core components

Interleukin-6 (\u3cem\u3eIL-6\u3c/em\u3e) rs1800796 and Cyclin Dependent Kinase Inhibitor (\u3cem\u3eCDKN2A/CDKN2B\u3c/em\u3e) rs2383207 Are Associated with Ischemic Stroke in Indigenous West African Men

Background—Inherited genetic variations offer a possible explanation for the observed peculiarities of stroke in sub – Saharan African populations. Interleukin–6 polymorphisms have been previously associated with ischemic stroke in some non-African populations. Aim—Herein we investigated, for the first time, the association of genetic polymorphisms of IL-6 and CDKN2A- CDKN2B and other genes with ischemic stroke among indigenous West African participants in the Stroke Investigative Research and Education Network (SIREN) Study. Methods—Twenty-three previously identified single nucleotide polymorphisms (SNPs) in 14 genes of relevance to the neurobiology of ischemic stroke were investigated. Logistic regression models adjusting for known cardiovascular disease risk factors were constructed to assess the associations of the 24 SNPs in rigorously phenotyped cases (N=429) of ischemic stroke (Men = 198; Women = 231) and stroke– free (N=483) controls (Men = 236; Women = 247). Results—Interleukin-6 (IL6) rs1800796 (C minor allele; frequency: West Africans = 8.6%) was significantly associated with ischemic stroke in men (OR = 2.006, 95% CI = [1.065, 3.777], p = 0.031) with hypertension in the model but not in women. In addition, rs2383207 in CDKN2A/CDKN2B (minor allele A with frequency: West Africans = 1.7%) was also associated with ischemic stroke in men (OR = 2.550, 95% CI = [1.027, 6.331], p = 0.044) with primary covariates in the model, but not in women. Polymorphisms in other genes did not show significant association with ischemic stroke. Conclusion—Polymorphisms rs1800796 in IL6 gene and rs2383207 in CDKN2A/CDKN2B gene have significant associations with ischemic stroke in indigenous West African men. CDKN2A/CDKN2B SNP rs2383207 is independently associated with ischemic stroke in indigenous West African men. Further research should focus on the contributions of inflammatory genes and other genetic polymorphisms, as well as the influence of sex on the neurobiology of stroke in people of African ancestry

Exploring Overlaps Between the Genomic and Environmental Determinants of LVH and Stroke: A Multicenter Study in West Africa

Background Whether left ventricular hypertrophy (LVH) is determined by similar genomic and environmental risk factors with stroke, or is simply an intermediate stroke marker, is unknown. Objectives We present a research plan and preliminary findings to explore the overlap in the genomic and environmental determinants of LVH and stroke among Africans participating in the SIREN (Stroke Investigative Research and Education Network) study. Methods SIREN is a transnational, multicenter study involving acute stroke patients and age-, ethnicity-, and sex-matched control subjects recruited from 9 sites in Ghana and Nigeria. Genomic and environmental risk factors and other relevant phenotypes for stroke and LVH are being collected and compared using standard techniques. Results This preliminary analysis included only 725 stroke patients (mean age 59.1 ± 13.2 years; 54.3% male). Fifty-five percent of the stroke subjects had LVH with greater proportion among women (51.6% vs. 48.4%; p \u3c 0.001). Those with LVH were younger (57.9 ± 12.8 vs. 60.6 ± 13.4; p = 0.006) and had higher mean systolic and diastolic blood pressure (167.1/99.5 mm Hg vs 151.7/90.6 mm Hg; p \u3c 0.001). Uncontrolled blood pressure at presentation was prevalent in subjects with LVH (76.2% vs. 57.7%; p \u3c 0.001). Significant independent predictors of LVH were age \u3c45 years (adjusted odds ratio [AOR]: 1.91; 95% confidence interval [CI]: 1.14 to 3.19), female sex (AOR: 2.01; 95% CI: 1.44 to 2.81), and diastolic blood pressure \u3e 90 mm Hg (AOR: 2.10; 95% CI: 1.39 to 3.19; p \u3c 0.001). Conclusions The prevalence of LVH was high among stroke patients especially the younger ones, suggesting a genetic component to LVH. Hypertension was a major modifiable risk factor for stroke as well as LVH. It is envisaged that the SIREN project will elucidate polygenic overlap (if present) between LVH and stroke among Africans, thereby defining the role of LVH as a putative intermediate cardiovascular phenotype and therapeutic target to inform interventions to reduce stroke risk in populations of African ancestry
