Correlates of hypertension among persons living with HIV at Livingstone Central Hospital: A cross sectional study

Background: Persons living with HIV (PLWH) are more likely to develop hypertension and cardiovascular disease than the HIV-negative population. The new hypertension guidelines by the American Heart Association (AHA) and the American College of Cardiology (ACC) lowered the definition of hypertension from systolic and diastolic blood pressure (BP) of ≥ 140/90mmHg to ≥ 130/80, respectively. This study was aimed at determining the prevalence and factors associated with hypertension in PLWH in Livingstone using the new hypertension diagnostic criteria. Methods: This was a cross-sectional study. We recruited 226 antiretroviral treated PLWH attending routine visits. Socio-demographic, health and clinical data including BP readings were collected. Interviewer-structured questionnaires adapted from the World Health Organization Stepwise approach to Surveillance ( WHO STEPs) and the international physical activity questionnaire (IPAQ) were used to collect data. Statistical evaluations were employed to elucidate relationships between hypertension and all response variables. Results: The prevalence of hypertension using the old and new guidelines was 16% and 42%, respectively. Factors significantly associated with increased and reduced odds of developing hypertension after adjustments in multivariate logistic regression were age, body mass index (BMI), employment status, fasting blood sugar (FBS) and table salt consumption, respectively (p<0.05 for all). Using the new AHA/ACC criteria for hypertension shifted the prevalence from 16% (old criteria) to 42%.Conclusion: The prevalence of hypertension in PLH in Livingstone was 42% and the major risk factors associated with hypertension in PLWH were increasing age, BMI and FBS. We recommend the inclusion of FBS in routine measurements in PLWH. The AHA/ ACC new guidelines should be reenforced in low-cost settings to increase the treatment of hypertension among PLWH.

A peculiarly characterised case of isoniazid-induced pellagra- 2 Ds and a C: a case report.

Niacin or tryptophan deficiency causes pellagra. Isoniazid interferes with the absorption of niacin and individuals on Isoniazid (INH) are at risk of pellagra. Isoniazid preventive therapy (IPT) is the administration of isoniazid to immunosuppressed individuals to prevent active tuberculosis (TB). IPT, in sub-Saharan Africa, the region worst hit by HIV and with a high TB prevalence, is recommended. A 40-year-old, HIV+ Zambian woman on Antiretroviral therapy for five years and IPT for three months presented with a four-day history of constipation, generalised body weakness and irrelevant talk. She complained of a generalised rash, sloughing off, and darkening of the skin on the face, neck, forearms, and dorsum of both feet. A physical examination revealed features of pellagra, and rapid response to oral niacin reaffirmed the diagnosis of pellagra. Unlike typical cases of pellagra presenting with the classic 3 Ds of Diarrhoea, Dementia and Dermatitis, our patient presented with constipation instead of diarrhoea. A consideration of Pellagra in HIV+ patients on IPT whose diet is mostly maize-based will be beneficial, even if the classic 3 Ds of diarrhoea, dementia, and dermatitis are not wholly present. A timely diagnosis and prompt treatment of pellagra can be lifesaving.

Cervical cancer and precancerous cervical lesions detected using visual inspection with acetic acid at Livingstone Teaching Hospital.

INTRODUCTION: cervical cancer (CaCx) is the second most common malignancy in women world-wide. Precancer screening aided by visual inspection with acetic acid (VIA) is an early diagnosis method used to detect the lesions that are high indicators of cancer in women. cervical cancer is more prevalent in the developing world affecting mainly women in the reproductive age group and is the commonest cancer among Zambian women. Therefore, the study aimed to determine the prevalence and factors associated with a positive VIA at Livingstone Teaching Hospital (LTH). METHODS: this was a cross-sectional study conducted at LTH among 329 women from Livingstone district aged 18 and above, who were coming for routine cervical cancer screening using VIA between 2019 and 2020. Demographic and clinical data were collected from the CaCx clinic. A positive VIA (precancerous cervical lesions) and cervical cancer were the primary and secondary outcome variables. A positive VIA was defined by presence of a dense ulcerative acetowhite area in the transformation zone of the cervix. Cervical cancer diagnosis was defined by presence of cancerous cells on histological examination by a qualified pathologist. Data were analyzed using Statistical package for social sciences (SPSS) version 22.0. Chi-square test, Mann-Whitney and logistic regression were the statistical methods used. RESULTS: the participants had a median (interquartile range) age of 37 (29, 44) years. Prevalence of CaCx and positive VIA were 6% (95% confidence interval (CI) 4, 9) and 19% (95% CI: 15, 24) respectively. At multivariable analysis, the factors associated with a positive VIA were alcohol consumption [odds ratio (OR) 0.30 (95% CI: 0.12, 0.74)] and HIV infection [OR 0.37 (95% CI: 0.19, 0.70)]. CONCLUSION: the study showed that precancerous cervical lesions are common among our study participants and it was influenced by alcohol consumption and HIV status. There is therefore need to enhance the screening programs using VIA in order to identify cancerous lesions at an early stage for early intervention in resource limited settings.

Nicolau syndrome following intramuscular benzathine penicillin injection: a case report.

Nicolau syndrome (NS) is a rare injection site reaction, following intramuscular injection of drugs characterized by severe pain, skin discoloration and varying level of tissue necrosis. The case outcomes vary from severe pain, atrophic ulcers to sepsis and limb amputation. We describe a case of the five-year-old girl with diagnosis of NS after intramuscular benzathine penicillin injection. The case was complicated with above the knee amputation of lower limb. This case report intends to remind clinicians that such rare cases should always be thought of in all patients receiving whatsoever drug via intramuscular injections.
