Atypical Mpox in a Nigerian Tertiary Health Facility.

BACKGROUND: We describe diverse clinical characteristics and course of confirmed mpox cases managed in a Nigerian tertiary health facility. METHODS: Clinical and epidemiologic data were analyzed, highlighting the unusual presentations of polymerase chain reaction (PCR)-confirmed mpox cases observed during the 2022 outbreak. RESULTS: Out of 17 suspected cases, 13 (76.4%) were PCR confirmed for mpox. The mean ± SD age for the participants was 28.62 ± 10.29 years (range, 2-55), of which 9 (64.3%) were male. Of the 13 PCR-confirmed cases, 5 (38.5%) had varicella zoster virus coinfection, 2 (15.4%) had HIV coinfection, and 1 (7.7%) had diabetes mellitus comorbidity. All patients experienced rash, with 6 (46.2%) having significant genital lesions and 1 (7.7%) having a severe perianal lesion. A lack of prodromal symptoms was reported in 3 (23.1%), and a prolonged prodrome (>1 week) occurred in 5 (38.5%). Skin lesions were polymorphic in 6 (46.2%), and solitary skin lesions occurred in 3 (23.1%), which persisted for >120 days in 7.7%. CONCLUSIONS: Clinical recognition, diagnosis, and prevention remain a concern in resource-limited settings. Our findings highlight the need to further evaluate unusual skin lesions and to include mpox screening for genital skin lesions that are presumed to be sexually transmitted infections. Revision of clinical case definition and enhanced surveillance are key to early recognition and prevention of spread.

Distribution pattern and prevalence of haematological cancers among adults in Abakaliki, South-Eastern Nigeria.

BACKGROUND: Haematological cancers are clonal diseases of the blood and blood-forming organs, with the distribution pattern not known in our locality. This study aimed to describe the distribution pattern and prevalence of haematological cancers among adults in Abakaliki, Nigeria. MATERIALS AND METHODS: This was an 8-year retrospective study in which the hospital records/case notes of adult patients diagnosed and managed for haematological cancers from May 2012 to April 2020 were reviewed. Data obtained were analysed with the SPSS software, version 20. RESULTS: One hundred and thirty-five cases of haematological cancers were included in the study, with 72 (53.4%) males and 63 (46.6%) females and male-to-female ratio of 1.1:1. The age range was 18-82 years, with a mean age of 49 ± 17 years. Lymphoid malignancies predominate more than myeloid (101 [74.8%] vs. 34 [25.2%]). The leukaemias were more predominant than the lymphomas and myeloma accounting for 48.2%, 36.3% and 7.4%, respectively. Chronic leukaemias were more common than the acute leukaemias with chronic lymphocytic leukaemia (CLL) being the most common accounting for 24.4% of haematological cancers. In general, non-Hodgkin's lymphoma (NHL) was the most common haematologic cancer accounting for 35 (25.9%), followed by CLL 33 (24.4%), chronic myeloid leukaemia (CML) 17 (12.6%), Hodgkin's lymphoma (HL) 14 (10.4%) and multiple myeloma (MM) 10 (7.4%). Others include acute lymphoblastic leukaemia (ALL) 9 (6.7%) and acute myeloblastic leukaemia (AML) 6 (4.4%). Myelodysplastic syndrome (MDS) and polycythaemia vera (PV), each contributed 3% while myelofibrosis (MF) and essential thrombocythaemia (ET) contributed 1.5% and 0.7%, respectively. CONCLUSION: This study has shown that haematological cancers are not uncommon in our locality with NHL being the most common, followed by CLL, CML, HL, MM, ALL, AML, MDS, PV. MF and ET in that order. The burden of haematological cancers in Ebonyi State, Nigeria is therefore significant and should be prioritised in health-care policy formulation and management.

Adherence Clubs to Improve Hypertension Management in Nigeria: Clubmeds, a Feasibility Study.

Background: Hypertension control remains a significant challenge in reducing the cardiovascular disease burden worldwide. Community peer-support groups have been identified as a promising strategy to improve medication adherence and blood pressure (BP) control. Objectives: The study aimed to evaluate the feasibility and impact of adherence clubs to improve BP control in Southeast Nigeria. Methods: This was a mixed-methods research involving a formative (pre-implementation) research, pilot study and process evaluation. Hypertensive patients in two communities were recruited into peer-support adherence clubs under the leadership of role-model patients to motivate and facilitate medication adherence, BP monitoring, and monthly medication delivery for six months. The primary outcome was medication adherence measured using visual analogue scale (VAS), with BP level at six months as a key secondary outcome. Results: We recruited a total of 104 participants. The mean age was 56.8 (SD-10.7) years, 72 (69.2%) were women, mean BP was 146.7 (SD-20.1)/86.9 (SD-11.2) mmHg, and the mean percentage of medication adherence on the VAS was 41.4% (SD-11.9%). At six months, 67 patients were assessed; self-reported adherence on the VAS increased to 57.3% (SD-25.3%) (mean difference between baseline and follow-up of 15.5%, p < 0.0001), while the mean BP decreased to 132.3 (SD-22.0)/82.9 (SD-12.2) mmHg (mean difference of 13.0 mmHg in systolic BP, p < 0.0001 and of 3.6 mmHg in diastolic BP, p = 0.02). Five in-depth interviews and four focus groups discussions were conducted as part of the qualitative analyses of the study. The participants saw hypertension as a big issue, with many unaware of the diagnosis, and they accepted the CLUBMEDS differential service delivery (DSD) model concept in hypertension. Conclusions: The study demonstrates that the implementation of adherence clubs for hypertension control is feasible and led to a statistically significant and clinically meaningful improvement in self-reported medication adherence, resulting in BP reduction. Upscaling the intervention may be needed to confirm these findings.

Early onset of neurological features differentiates two outbreaks of Lassa fever in Ebonyi state, Nigeria during 2017-2018.

Lassa fever (LF) is an acute viral haemorrhagic illness with various non-specific clinical manifestations. Neurological symptoms are rare at the early stage of the disease, but may be seen in late stages, in severely ill patients.The aim of this study was to describe the epidemiological evolution, socio-demographic profiles, clinical characteristics, and outcomes of patients seen during two Lassa fever outbreaks in Ebonyi State, between December 2017 and December 2018. Routinely collected clinical data from all patients admitted to the Virology Centre of the hospital during the period were analysed retrospectively. Out of a total of 83 cases, 70(84.3%) were RT-PCR confirmed while 13 (15.7%) were probable cases. Sixty-nine (83.1%) patients were seen in outbreak 1 of whom 53.6% were urban residents, while 19%, 15%, and 10% were farmers, students and health workers respectively. There were 14 (16.8%) patients, seen in second outbreak with 92.9% rural residents. There were differences in clinical symptoms, signs and laboratory findings between the two outbreaks. The case fatality rates were 29.9% in outbreak 1 and 85.7% for outbreak 2. Neurological features and abnormal laboratory test results were associated with higher mortality rate, seen in outbreak 2. This study revealed significant differences between the two outbreaks. Of particular concern was the higher case fatality during the outbreak 2 which may be from a more virulent strain of the Lassa virus. This has important public health implications and further molecular studies are needed to better define its characteristics.
