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.

Effect of multiple intervention models on uptake of HIV testing services and sexual behaviour among residents of military cantonments in south-east Nigeria.

Background: HIV testing and counselling (HTC) has been a viable tool in controlling the spread of HIV/AIDS, and serves as the entry point in the HIV care and treatment cascade. In Africa, HIV-related morbidity and mortality are high with thousands still unaware of their HIV status. This study assessed the effect of on-site multiple HIV control interventions on the uptake of HTC services, knowledge and sexual behaviour among residents of two military cantonments [barracks] in south-east Nigeria. Methods: A quasi-experimental study was conducted among residents of cantonments in two states in Nigeria. A multistage sampling technique was used to select 350 respondents each at intervention and control sites. A pre-tested interviewer-administered questionnaire was used to collect information. On-site HTC services were established, with the training of HTC counsellors and peer educators. HIV awareness carnivals, with information, education and communication activities were conducted. Data were analysed with SPSS software and statistical tests carried out at 5% level of significance. Results: There was a statistically significant increase in the uptake of HTC services from 41.1% pre-intervention to 81.1% post-intervention (χ2 = 113.8, p < 0.001). Also, knowledge about HIV improved significantly from 35.4% to 98.8% (p < 0.001) in the intervention group, together with avoidance of risky sexual behaviour. Conclusion: The study demonstrated the effectiveness of multiple on-site intervention models in improving HIV knowledge, uptake of HTC services, and sexual behaviour among diverse cantonment residents. Establishing on-site HTC services and a constellation of awareness events will contribute significantly towards HIV prevention and control among high-risk populations.

Lassa fever - full recovery without ribavarin treatment: a case report.

BACKGROUND: Lassa fever is a rodent-borne zoonosis that clinically manifests as an acute hemorrhagic fever. It is treated using ribavarin. Surviving Lassa fever without receiving the antiviral drug ribavarin is rare. Only few cases have been documented to date. CASE PRESENTATION: We report a case of a 59-year old female with fever who was initially thought to have acute pyelonephritis and sepsis syndrome with background malaria. Further changes in her clinical state and laboratory tests led to a suspicion of Lassa fever. However at the time her laboratory confirmatory test for Lassa fever returned, her clinical state had improved and she made full recovery without receiving ribavarin. Her close contacts showed no evidence of Lassa virus infection. CONCLUSION: This report adds to the literature on the natural history of Lassa fever; and that individuals may survive Lassa fever with conservative management of symptoms of the disease and its complications.

High population frequencies of APOL1 risk variants are associated with increased prevalence of non-diabetic chronic kidney disease in the Igbo people from south-eastern Nigeria.

BACKGROUND: Continental Africa is facing an epidemic of chronic kidney disease (CKD). APOL1 risk variants have been shown to be strongly associated with an increased risk for non-diabetic kidney disease including HIV nephropathy, primary non-monogenic focal and segmental glomerulosclerosis, and hypertension-attributed nephropathy among African ancestry populations in the USA. The world's highest frequencies of APOL1 risk alleles have been reported in West African nations, overlapping regions with a high incidence of CKD and hypertension. One such region is south-eastern Nigeria, and therefore we sought to quantify the association of APOL1 risk alleles with CKD in this region. METHODS: APOL1 risk variants were genotyped in a case-control sample set consisting of non-diabetic, CKD patients (n = 44) and control individuals (n = 43) from Enugu and Abakaliki, Nigeria. RESULTS: We found a high frequency of two APOL1 risk alleles in the general population of Igbo people of south-eastern Nigeria (23.3%). The two APOL1 risk allele frequency in the CKD patient group was 66%. Logistic regression analysis under a recessive inheritance model showed a strong and significant association of APOL1 two-risk alleles with CKD, yielding an odds ratio of 6.4 (unadjusted p = 1.2E-4); following correction for age, gender, HIV and BMI, the odds ratio was 4.8 (adjusted p = 5.1E-03). CONCLUSION: APOL1 risk variants are common in the Igbo population of south-eastern Nigeria, and are also highly associated with non-diabetic CKD in this area. APOL1 may explain the increased prevalence of CKD in this region.

Tuberculosis treatment default in a large tertiary care hospital in urban Nigeria: prevalence, trend, timing and predictors.

OBJECTIVES: Few studies have investigated tuberculosis treatment default in tertiary care settings. We aimed to determine the prevalence, trend, timing and predictors of defaulting from tuberculosis treatment in a Nigerian tertiary hospital. METHODS: Data entered from 2006 to 2010 in the Federal Medical Centre, Abakaliki, tuberculosis treatment register were sorted into six treatment outcomes. Five outcomes were combined into one variable called 'non-defaulters' and were compared with "defaulters". The statistical analysis was conducted using SPSS. RESULTS: Of 671 tuberculosis patients, 192 (28.6%) defaulted. Of these, 126 (66%) were ≥30 years old, and 115 (60%) had pulmonary tuberculosis. Furthermore, 106 (55%) were males, and 125 (65%) lived in a rural area. The annual proportion of defaulters dropped from 34.8% to 20.6%, but the decreasing trend was not statistically significant (P=0.132 for trend). Of the defaulters, 148 (77.1%) defaulted during their intensive phase of treatment. The median default time was 7 (IQR 5-8) weeks. The independent predictors of treatment default were older age (aOR 1.5), rural residence (aOR 2.3), and HIV seropositivity (aOR, 2.8). CONCLUSION: TB treatment default is high and must be reduced. This may be achieved through improved rural DOT, further patient education, and enhanced coordination of TB/HIV care.

Treatment outcome of HIV-associated tuberculosis in a resource-poor setting.

Nigeria is among the countries with the world's highest tuberculosis (TB) burden, and HIV/TB co-infection is an important cause of mortality. We evaluate the treatment outcome of HIV-infected TB patients in Abakaliki, Nigeria. A retrospective cohort study of all TB patients registered at a tertiary hospital between January 2006 and December 2010 was conducted. Of 671 TB patients, 189 (28.2%) were HIV co-infected. Of these, 147 (77.8%) had pulmonary TB and 42 (22.2%) had extra-pulmonary TB. The overall treatment success rate was 52.4% (n = 99) and the defaulted in treatment rate was 30.2% (n = 57). Twenty-one (11.1%) died, and one (0.5%) had treatment failure. Younger age group (<15 years; P = 0.0024) and smear-positive status (P = 0.0056) were independent predictors of successful treatment. TB/HIV co-infection is associated with high mortality and alarming default rates during treatment.

Consequences of HIV testing without consent.

The objective of this study is to explore the HIV-infected individuals' experience with HIV testing, counselling, disclosure of diagnosis and subsequent life events following diagnosis. The method used is a questionnaire survey of 340 consecutive HIV-positive victims, seen in two health institutions in southeast Nigeria within a one-year-period, November 2003 to October 2004. Three hundred and twenty respondents answered the questionnaire, 121 were men and 199 women, with 79% in the age range 20-39 years. Most respondents had known their HIV status for 3.2 (+/-1.1) years and the majority are in the lower social class. About 80% reported that their consent for HIV test was not asked for, resulting in feelings of fear, disbelief, shock and embarrassment on learning about their HIV status. Despite the initial reaction to the diagnosis, majority (81.9%) expressed satisfaction with the pattern of disclosure of diagnosis. There was some reluctance to inform spouse/partner of the diagnosis especially among asymptomatic, unmarried, childless or divorced victims. A serodiscordant couple resulted in mistrust and increased incidence of abandonment. Apart from spouse/partner the respondents are more likely to inform their siblings of the diagnosis than parents, children or friends. Despite being supportive, the respondents are more likely to suffer more neglect from siblings than their spouse (P<0.05) but the risk of being abandoned was more with the spouse than with siblings (P<0.05). Only 32.6% of the 129 respondents on antiretroviral therapy are regular with it mainly because of cost and non-availability of drugs. Default in treatment was more evident among the unmarried, those with low educational status and treatment with antiretroviral drugs for more than two years. Proper pre- and post-test counselling, promotion of behavioural change among the society about HIV/AIDS and provision of support and cost-effective care for HIV victims is advocated.
