An HIV-1 infected patient with Neurofibromatosis type 1: A case report

Background: Although HIV-1 infection predisposes an individual to well defined neoplasia, neurofibromas have not been reported as some of the typical ones. The association between HIV-1 infection and neurofibromatosis type 1, a genetic disorder, should be of interest because HIV infection could alter the natural biology of its cutaneous manifestations. However, reports on simultaneous occurrence of these conditions in an individual are rare.Method: The case records of a 30 year old HIV 1 positive female receiving care at the Jos University teaching hospital centre and a review of the relevant literature was utilised.Result: We present a 30 year old HIV positive woman with florid cutaneous lesions of familial neurofibromatosis type  1 who had adequate response to antiretroviral therapyConclusion: HIV infection and treatment did not seem toaffect the clinico- pathological features of the neurofibromatosis lesions.Key Words: Neurofibromatosis type 1, HIV Infection, cutaneous lesions, HAAR

Secondary hyperparathyroidism among Nigerians with chronic kidney disease

Backround: Secondary hyperparathyroidism (SHPT) is a manifestation of chronic kidney disease mineral bone disorder (CKD-MBD). SHPT is common in patients with chronic kidney disease (CKD) and is associated with significant morbidity and mortality.Methods: A cross- sectional descriptive study involving 230 patients with CKD. Results: The mean age of the study population was 44.17±15.24 years. The median intact parathyroid hormone and alkaline phosphatase levels were 96pg/ml (range 4-953pg/ml) and 88 iu/l (range 10-800 iu/l) respectively. The mean (with standard deviation) calcium, serum phosphate, calcium phosphate product and haemoglobin levels were 2.22±0.29mmol/l, 1.8±0.62mmol/l, 3.94±1.42mmol2/l2 and 9.90±1.87g/dl respectively. Majority of patients had advanced CKD with 70.3% of patients in stage G5. The prevalence rates of SHPT, hypocalcaemia, hyperphosphataemia, elevated alkaline phosphatase and elevated calcium phosphate product were 55.2%, 34.8%, 66.1%, 42.2% and 25.2% respectively. Univariate analysis revealed that SHPT was associated with hypocalcaemia, hyperphosphataemia, elevated alkaline phosphatase, proteinuria, anaemia, hypertension, left ventricular hypertrophy and stage of kidney disease; being worse with advancing kidney disease. Independently associated with SHPT were hypocalcaemia (OR=4.84), hyperphosphataemia (OR=3.06), and elevated alkaline phosphatase (OR=2.04).Conclusion: The prevalence of SHPT in CKD is high, occurs early and is independently associated with hypocalcaemia, hyperphosphataemia and elevated alkaline phosphatase. The prevalence of SHPT also increases with worsening renal function.Keywords: Secondary hyperparathyroidism, chronic kidney disease, intact parathyroid hormone, hypocalcaemia, hyperphosphataemia, elevated alkaline phosphatase

Predictors of adherence to antiretroviral therapy among human immunodeficiency virus patients in Jos University Teaching Hospital, Nigeria

Introduction: Sustained optimal adherence to antiretroviral therapy (ART) is required for long-term suppression of viral replication. However, adherence level in Jos, Nigeria has been reported to be below optimal adherence, thus this study investigates the predictors of adherence to antiretroviral therapy among Human Immunodeficiency Virus (HIV) patients there. Methods: A validated and pretested questionnaire was used in this cross-sectional study to collect data on sociodemographic characteristics, duration of being on ART, alcohol consumption, presence of symptoms, drug type and disclosure status from 224 randomly selected adult HIV patients. Chi-square and binary logistics regression were used for data analysis. Level of significance was set at 0.05. Results: Only 14.3% of the respondents had optimal adherence. Adherence to ART is significantly associated with gender (p = 0.043), duration of ART use (p = 0.041), alcohol (p = 0.029), drug type (p = 0.001), and disclosure status (p = 0.004). Binary logistics regression reveals that females are 2.4 times more likely to have optimal adherence than males, patients on ART for over 10 years are 2.5 times more likely to have optimal adherence than those less than 10 years, and patients with disclosed HIV status are 3.3 times more likely to have optimal adherence than those who had not. Conclusion: Generally, the patients had suboptimal adherence. Being female, having longer duration on ART and disclosure status are predictors for optimal adherence. Intervention with emphasis on males and new patients on ART is recommended to educate on optimal adherence and motivate patients to disclose their status

Evaluation of In Vitro Activity of Essential Oils against Trypanosoma brucei brucei and Trypanosoma evansi

Essential oils (EOs) from Cymbopogon citratus (CC), Eucalyptus citriodora (EC), Eucalyptus camaldulensis (ED), and Citrus sinensis (CS) were obtained by hydrodistillation process. The EOs were evaluated in vitro for activity against Trypanosoma brucei brucei (Tbb) and Trypanosoma evansi (T. evansi). The EOs were found to possess antitrypanosomal activity in vitro in a dose-dependent pattern in a short period of time. The drop in number of parasite over time was achieved doses of 0.4 g/ml, 0.2 g/mL, and 0.1 g/mL for all the EOs. The concentration of 0.4 g/mL CC was more potent at 3 minutes and 2 minutes for Tbb and T. evansi, respectively. The GC-MS analysis of the EOs revealed presence of Cyclobutane (96.09%) in CS, 6-octenal (77.11%) in EC, Eucalyptol (75%) in ED, and Citral (38.32%) in CC among several other organic compounds. The results are discussed in relation to trypanosome chemotherapy

Frequency of Cryptococcal Meningitis in HIV-1 Infected Patients in North Central Nigeria

Background: Cryptococcal meningitis (CM) is the most common severe life threatening fungal infection in AIDS patients. It is an important cause of morbidity and mortality. There is paucity of data on the prevalence of CM in Nigeria. We aimed to determine the frequency of CM, the clinical presentation and immunological profile.Methods: A cross sectional study was carried out at the Jos University Teaching Hospital (JUTH), A total of 100 HIV-1 infected patients suspected of having meningitis or meningoencephalitis were subjected to cerebrospinal fluid (CSF) analysis (including Indian ink preparation and fungal culture by conventional methods) and CD4 count was determined using flow cytometry (count bit Y-R 1004 Partec Muster Germany).Results: The freguency of CM was 36% in our cohort. The commonest clinical presentation included headache (100.0%), neck stiffness (77.8%), fever (72.0%), vomiting (55.6%), personality changes (55.6%), photophobia (27.8%) and convulsions (27.8%). The mean duration of symptoms was 24 ±22 days with a median of 17 days. The mean CD4 count was 89±60 cells/mm3 with a median of 82 cells/mm3.Conclusion: The high prevalence of CM and the associated severe immunosuppression underscores the importance of early diagnosis of HIV infection which may reduce the incidence of CM. There is the urgent need for access to Amphotericin B and fluconazole in resource constrained settings in addition to a wide access to HAART.Key words: Cryptococcal meningitis, HIV, North central Nigeri

Toward an Understanding of Disengagement from HIV Treatment and Care in Sub-Saharan Africa: A Qualitative Study

Background: The rollout of antiretroviral therapy in sub-Saharan Africa has brought lifesaving treatment to millions of HIV-infected individuals. Treatment is lifelong, however, and to continue to benefit, patients must remain in care. Despite this, systematic investigations of retention have repeatedly documented high rates of loss to follow-up from HIV treatment programs. This paper introduces an explanation for missed clinic visits and subsequent disengagement among patients enrolled in HIV treatment and care programs in Africa. Methods and Findings: Eight-hundred-ninety patients enrolled in HIV treatment programs in Jos, Nigeria; Dar es Salaam, Tanzania; and Mbarara, Uganda who had extended absences from care were tracked for qualitative research interviews. Two-hundred-eighty-seven were located, and 91 took part in the study. Interview data were inductively analyzed to identify reasons for missed visits and to assemble them into a broader explanation of how missed visits may develop into disengagement. Findings reveal unintentional and intentional reasons for missing, along with reluctance to return to care following an absence. Disengagement is interpreted as a process through which missed visits and ensuing reluctance to return over time erode patients' subjective sense of connectedness to care. Conclusions: Missed visits are inevitable over a lifelong course of HIV care. Efforts to prevent missed clinic visits combined with moves to minimize barriers to re-entry into care are more likely than either approach alone to keep missed visits from turning into long-term disengagement

Determination of capsaicin content and Pungency Level of Five Different Peppers Grown in Nigeria.

Abstract: The determination of capsaicin content in five different peppers grown in Nigeria without the need for a derivatization step is here presented. Extraction of capsaicin was done using methanol as solvent and capillary Gas Chromatography-Mass Spectrometry used for quantitation. "Nsukka" Yellow pepper (Capsicum chinense) had the highest concentration of capsaicin (9.177 ± 0.268mg/g) and pungency level (146,823.20 SHU), whereas, "Zaria tatashe" (Capsicum annuum) had the lowest concentration (1.189 ± 0.073mg/g) and pungency leve

Treatment Outcomes in a Decentralized Antiretroviral Therapy Program: A Comparison of Two Levels of Care in North Central Nigeria

Background. Decentralization of antiretroviral therapy (ART) services is a key strategy to achieving universal access to treatment for people living with HIV/AIDS. Our objective was to assess clinical and laboratory outcomes within a decentralized program in Nigeria. Methods. Using a tiered hub-and-spoke model to decentralize services, a tertiary hospital scaled down services to 13 secondary-level hospitals using national and program guidelines. We obtained sociodemographic, clinical, and immunovirologic data on previously antiretroviral drug naïve patients aged ≥15 years that received HAART for at least 6 months and compared treatment outcomes between the prime and satellite sites. Results. Out of 7,747 patients, 3729 (48.1%) were enrolled at the satellites while on HAART, prime site patients achieved better immune reconstitution based on CD4+ cell counts at 12 (P < 0.001) and 24 weeks (P < 0.001) with similar responses at 48 weeks (P = 0.11) and higher rates of viral suppression (<400 c/mL) at 12 (P < 0.001) and 48 weeks (P = 0.03), but similar responses at 24 weeks (P = 0.21). Mortality was 2.3% versus 5.0% (P < 0.001) at prime and satellite sites, while transfer rate was 8.7% versus 5.5% (P = 0.001) at prime and satellites. Conclusion. ART decentralization is feasible in resource-limited settings, but efforts have to be intensified to maintain good quality of care

Comparative incidence of adverse drug reaction during the first and subsequent year of antiretroviral therapy in a Nigerian HIV infected Cohort

Background: Despite close to two decades of antiretroviral therapy (ART) in Nigeria, data on late on-onset ART-associated adverse drug reactions (ADRs) are sparse. Objectives: To describe early and late-onset ADRs and compare their incidence in an outpatient HIV positive Cohort on ART. Method: We described the incidence of clinical ADRs identified and documented in an outpatient clinic cohort of HIV-positive patients treated between June 2004 and December 2015 at a tertiary health facility in Nigeria. Incidence rates of ADRs during the first and subsequent years of ART were compared. Results: of the 13,983 patients\u2019 data analyzed, 9317 were females (66%), and those in the age bracket of 25 to 45 years made up 78% of the studied population. During 52,411 person-years (py) of ART, 1485 incident ADRs were recorded; Incidence rate (IR) 28.3 (95% confidence interval [CI] 26.9:29.8) ADRs per 1000 person-years (py) of ART. The IR of ADRs was about two times higher in the first year of ART compared to subsequent years of treatment; crude incidence rate ratio (IRR) 1.77 (95% CI 1.59:1.97). Anemia, hypersensitivity reactions, and nervous system disorders had 7, 23, and 5 times higher incidence, respectively, in the first year of therapy, compared to subsequent years. Conclusion: The first year of ART is the period of highest risk of ADRs. Individual and programmatic treatment success in resource-limited settings requires strategies for early identification and management of ADR during the period of greatest risk of ADRs

Patient Experiences of Decentralized HIV Treatment and Care in Plateau State, North Central Nigeria: A Qualitative Study

Background. Decentralization of care and treatment for HIV infection in Africa makes services available in local health facilities. Decentralization has been associated with improved retention and comparable or superior treatment outcomes, but patient experiences are not well understood. Methods. We conducted a qualitative study of patient experiences in decentralized HIV care in Plateau State, north central Nigeria. Five decentralized care sites in the Plateau State Decentralization Initiative were purposefully selected. Ninety-three patients and 16 providers at these sites participated in individual interviews and focus groups. Data collection activities were audio-recorded and transcribed. Transcripts were inductively content analyzed to derive descriptive categories representing patient experiences of decentralized care. Results. Patient participants in this study experienced the transition to decentralized care as a series of &quot;trade-offs.&quot; Advantages cited included saving time and money on travel to clinic visits, avoiding dangers on the road, and the &quot;family-like atmosphere&quot; found in some decentralized clinics. Disadvantages were loss of access to ancillary services, reduced opportunities for interaction with providers, and increased risk of disclosure. Participants preferred decentralized services overall. Conclusion. Difficulty and cost of travel remain a fundamental barrier to accessing HIV care outside urban centers, suggesting increased availability of community-based services will be enthusiastically received
