Prevalence and determinants of selected cardio-metabolic risk factors among people living with HIV/AIDS and receiving care in the South West Regional Hospitals of Cameroon: a cross-sectional study.

OBJECTIVE: Metabolic disorders and cardiovascular risk factors are not routinely assessed in the care of HIV patients in developing countries, known to have the highest disease burden. We described the prevalence and factors associated with major cardio-metabolic risk factors (obesity, diabetes and hypertension) in HIV/AIDS patients. RESULTS: The prevalence of diabetes, hypertension and obesity were 11.3% (95% CI 8.10-15.43), 24.8% (95% CI 20.1-30.0) and 14.5% (95% CI 11.1-19.3) respectively. Central obesity and high alcohol intake were the factors significantly associated with diabetes mellitus, while central obesity and overweight/obesity were significantly associated with having hypertension. Short duration of antiretroviral therapy was the significant predisposing factor for obesity. On multivariate analyses, the only association observed was between central obesity and diabetes (Adjusted OR 2.52, 95% CI 1.01-6.30, P = 0.048). Conclusively, DM, HTN and obesity are highly prevalent in HIV/AIDS patients in the SWR hospitals of Cameroon, with that of DM and obesity being higher than that seen in the general population while that of HTN equaling that of the general population. Awareness of these data among clinicians involved in the management of these patients should be emphasized.

Vitamin B12 deficiency neuropathy; a rare diagnosis in young adults: a case report.

BACKGROUND: Vitamin B12 deficiency is a metabolic disorder with many causes. It often presents with megaloblastic anaemia and neurological disorders which entail prompt treatment. The diagnosis of Vitamin B12 deficiency is challenging in resource limited-settings due to limited access to diagnostic tools and unfamiliarity with the disease, owing to its rarity especially in young people. CASE PRESENTATION: A 28 year old female Cameroonian presented with progressive burning painful sensations on the upper trunk, paraesthesia and numbness of the upper and lower limbs for a period of 5 years. Before presenting to us, she had consulted in numerous health institutions for which she had been treated for diverse pathologies with no relieve of symptoms. After clinical and laboratory evaluation, a diagnosis of vitamin B12 deficiency-associated neuropathy was made. She was placed on oral vitamin B12 supplements at 2 mg daily for 3 months. Follow up was marked by good clinical recovery after 1 month of therapy. CONCLUSION: Vitamin B12 deficiency neuropathy is a rare debilitating disease that affects mostly the elderly. However; young adults with neuropathic symptoms warrant a high index of suspicion. Peripheral blood smears and complete blood counts are sufficiently diagnostic in resource-limited settings.

Occurrence of Emery-Dreifuss muscular dystrophy in a rural setting of Cameroon: a case report and review of the literature.

BACKGROUND: Emery-Dreifuss muscular dystrophy is a rare genetic muscular disease, presenting mainly with contractures, weakness and cardiac conduction abnormalities. Its clinical and laboratory similarities to other muscular dystrophies, and rarity poses diagnostic challenges, requiring a high index of suspicion in resource limited settings. CASE PRESENTATION: An 8 year old sub-Saharan male presented with rigidity and deformity of both elbows and ankles, and weakness of the upper limbs and lower limbs for duration of 4 months. This progressed to inability to stand and walk. There was no mental impairment. Physical examination was remarkable for contractures of the elbows and ankles, and wasting of muscles of the limbs and trunk, with a scapulohumeroperoneal pattern, and tachycardia. After laboratory investigations, a diagnosis of Emery-Dreifuss muscular dystrophy was suspected. Physiotherapy was started, wheel chair was prescribed, and referral to a specialist center was done for appropriate management. CONCLUSIONS: Emery-Dreifuss muscular dystrophy is a rare disabling muscular disease which poses a diagnostic challenge. High index of suspicion is paramount for its early diagnoses to prevent orthopedic and cardiac complications. Prompt diagnosis and management is essential to improve on the prognosis of this disease.

Chlamydia trachomatis-induced Fitz-Hugh-Curtis syndrome: a case report.

BACKGROUND: Fitz-Hugh-Curtis syndrome is defined as perihepatitis associated with pelvic inflammatory disease. Chlamydia trachomatis is one of its most common aetiologies. This syndrome usually presents with right upper quadrant abdominal pain mimicking other hepatobiliary and gastrointestinal pathologies, hence, posing a diagnostic dilemma in settings with limited diagnostic tools. CASE REPORT: A 32 year old African female presented with acute right upper quadrant abdominal pain and vaginal discharge, for which she had previously received treatment in another health center with no improvement. Clinical and laboratory findings were suggestive of Fitz-Hugh-Curtis syndrome. Five days after treatment with oral doxycycline, the patient showed marked clinical improvement. CONCLUSION: Fitz-Hugh-Curtis syndrome is a common cause of right upper quadrant pain which is often under diagnosed in poor communities. Hence, it should be included as a differential diagnosis in patients presenting with right upper quadrant pain, especially in females of reproductive age.

Have Non-physician Clinicians Come to Stay? Comment on "Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians".

A decade ago, sub-Saharan Africa accounted for 24% of the global disease burden but was served by only 4% of the global health workforce. The chronic shortage of medical doctors has led other health professionals especially nurses to perform the role of healthcare providers. These health workers have been variously named clinical officers, health officers, physician assistants, nurse practitioners, physician associates and non-physician clinicians (NPCs) defined as "health workers who have fewer clinical skills than physicians but more than nurses." Although born out of exigencies, NPCs, like previous initiatives, seem to have come to stay and many more medical doctors are being trained to care for the sick and to supervise other health team members. Physicians also have to assume new roles in the healthcare system with consequent changes in medical education.

Prevalence and correlates of depressive symptoms in adult patients with pulmonary tuberculosis in the Southwest Region of Cameroon.

BACKGROUND: Tuberculosis (TB) remains a global health challenge and depression is a significant contributor to the global burden of disease. Current evidence suggests that there is an association between depressive symptoms and TB, lower adherence to treatment, and increased morbidity and mortality. However, there is paucity of data regarding these associations in Cameroon. This study aimed to determine the prevalence and correlates of depression in adult patients with pulmonary TB (PTB) in the Southwest Region of Cameroon. METHODS: A hospital-based cross-sectional study involving 265 patients with PTB was conducted from 2(nd) January to 31(st) March 2015 in the Limbe Regional Hospital and the Kumba District Hospital. Depression was diagnosed using the standard nine-item Patient Health Questionnaire, and classified as none, mild or moderate. Logistic regressions were used to investigate correlates of depression in these patients. RESULTS: Of the 265 patients (mean age 36.9 ± 10 years) studied, 136 (51.3 %) were female. The prevalence of depression was 61.1 % (95 % CI: 55.1-66.8), with a significant proportion (36.6 %) having mild depression. Multivariable logistic regression analysis showed that being female (aOR = 3.0, 95 % CI (1.7-5.5), P < 0.001), having a family history of mental illness (aOR = 2.5, 95 % CI: 1.3-5.4, P > 0.05), being on retreatment for TB (aOR = 11.2, 95 % CI: 5.2-31.1, P < 0.001), having discontinued treatment (aOR = 8.2, 95 % CI: 1.1-23.3, P < 0.05) and having a HIV/TB co-infection (aOR = 2.5, 95 % CI: 1.2-6.5, P < 0.001) were factors associated with having a higher chance of being depressed. CONCLUSION: Our study suggests that there is a high prevalence of depression among PTB patients, with more than one in two patients affected. Multidisciplinary care for TB patients involving mental health practitioners is highly encouraged, especially for high-risk groups.

Hypertension, an Emerging Problem in Rural Cameroon: Prevalence, Risk Factors, and Control.

Background. Despite the increasing trends suggesting that hypertension is a growing public health problem in developing countries, studies on its prevalence, associated risk factors, and extent of blood pressure control have been inequitably done in urban and rural communities in these countries. We therefore aimed to determine the prevalence of hypertension and extent of blood pressure control in rural Cameroon. Methods. This was a community-based cross-sectional study conducted in rural Cameroon (the Moliwe Health Area). Participants aged 21 years and above were recruited by a probability proportional to size multistage sampling method, using systematic sampling for household selection and random sampling for participant selection. Blood pressure, weight, and height were measured by standard methods. Hypertension was defined as BP ≥ 140/90 mmHg. Results. The prevalence of hypertension among the 733 participants recruited was 31.1% (95% CI: 27.8-34.6) and 71% (95% CI: 58.7-81.7) of these hypertensive patients were newly diagnosed. Only 21.2% (95% CI: 12.1-33.3) of known hypertensives had a well controlled BP. Age, obesity, low educational status, and being married were associated with HTN after adjusting for confounders. Conclusions. The high prevalence of hypertension and inadequate BP control among known hypertensives in rural Cameroon warrants greater sensitization and regular screening to reduce hypertension-related morbidity and mortality.
