Antimicrobial sensitivity profile and bacterial isolates among suspected pyogenic meningitis patients attending at Hawassa University Hospital: Cross-sectional study.

BACKGROUND: Bacterial meningitis is a serious inflammation of the meninges. Antimicrobial therapy on early cerebrospinal fluid (CSF) examination has an important role in diagnosis. The disease is still challenging in developing countries because of poor (diagnostic set-up, socioeconomic conditions, management), and misuse of antimicrobial therapy results in emerging antimicrobial-resistant strains. Therefore, this hospital based cross sectional study was aimed to assess the antimicrobial sensitivity profile and bacterial isolates among patients suspected of pyogenic meningitis at Hawassa University Hospital from February 2017 to 2018. RESULTS: A total of 394 patients suspected as meningitis were included. Of these 210 (53.3%) were males and 184 (46.7%) were females. The carriage rate of bacterial pathogens was 27(6.9%). The common clinical presentations were fever 330 (83.8%), headache 205 (52.0%) and neck stiffness 179(45.4%) followed by altered mental status 125(31.7%). Neck stiffness P = 0.001 (AOR = 1.18, 95% CI 1.06-6.53), Hx of seizure P = 0.043, (AOR = 1.39, 95% CI 1.15-5.99), Nuchal rigidity P = 0.001* (AOR = 1.26, 95% CI 1.06-4.48) were significantly associated with culture positivity. The pathogens isolated in this study were N. meningitidis the most frequent isolate 12(44.4%) followed by S. pneumoniae 5 (18.5%), E. coli 4(14.8%), H. influenza 3(13.6%), S. aureus 2(11.1%) and K. pneumoniae 1(3.7%). S. pneumoniae was (100%) resistance to penicillin, (80%) amoxicillin, and (20%) Cefotaxime. S. aureus was (100%) resistant to penicillin, amoxicillin, and ciprofloxacin. N. meningitidis was (100%) resistant to penicillin, (66.7%) Ceftriaxone and (41.7%) chloramphenicol. In this study a single isolate was also resistant to a different antibiotic. CONCLUSION: The prevention of bacterial meningitis needs serious attention since the isolated bacteria showed single and multiple antimicrobial susceptibility patterns and the variable nature of isolated etiological agents makes it reasonable to provide continuous future updates on local resistance of common antibiotics and optimize the most frequent bacteria associated with meningitis in the hospital. Therefore; further, survey study with a better design of antimicrobial susceptibility at large scale to control the spread of antibiotic-resistant bacteria and the change in the causative organism of bacterial meningitis in the study area and at a national level is required.

Socio-demographic characteristics, clinical profile and prevalence of existing mental illness among suicide attempters attending emergency services at two hospitals in Hawassa city, South Ethiopia: a cross-sectional study.

BACKGROUND: Suicide is a major public health problem worldwide. It contributes for more than one million deaths each year. Since previous suicidal attempt was considered as the best predictor of future suicide, identifying factors behind suicidal attempt are helpful to design suicide prevention strategies. The aim of this study was to assess socio-demographic characteristics, clinical profile and prevalence of existing mental illness among patients presenting with suicidal attempt to emergency services of general hospitals in South Ethiopia. METHODS: We conducted a cross-sectional study on patients presenting with complications of suicidal attempt to emergency departments of two general hospitals in Hawassa city from November, 2014 to August, 2015. Data was collected using semi-structured questionnaire which contained socio-demographic and clinical variables. The Mini International Neuropsychiatric Interview version 5 (MINI PLUs) was used to assess the prevalence of existing mental illness among study participants. Data was entered and analyzed using IBM SPSS statistics 21 software package. RESULTS: A total of 96 individuals were assessed, of whom 56 (58.3%) were females. The mean age of study participants was 21.5 (8.0) years. The majority, 75 (78.1%), of the study participants were aged below 25 years. Ingesting pesticide poisons and corrosive agent were used by the majority to attempt suicide. Mental illness was found in only three (3.1%) of the study participants. Impulsivity (the time between decision to attempt suicide and the actual attempt of less than 5 min) was reported by 30 (31.2%) of the study participants, of whom 18 (60%) were males. Males were found three times more likely to attempt suicide impulsively than women (COR = 3.0, 95% CI 1.2-7.3). Quarreling with family members, facing financial crisis, and having unplanned and unwanted pregnancy were reported by the majority of study participants as immediate reasons to attempt suicide. CONCLUSIONS: The presence of stressful life events and impulsivity behind suicidal behavior of the younger generation implies that designing suicide prevention strategies for this group is crucial. Moreover, further research is needed to systematically examine the relationship between the presence of mental illness and suicidal attempt with a larger sample size and more robust methodology.

Spectrum of cardiovascular diseases in six main referral hospitals of Ethiopia.

BACKGROUND: The spectrum of cardiovascular diseases varies between and within countries, depending on the stage of epidemiological transition and risk factor profiles. Understanding this spectrum requires regional and national data for each region or country. This study was designed to determine the spectrum of cardiovascular diseases in six university hospitals in Ethiopia. METHODS: This is a cross-sectional study of the spectrum of cardiovascular diseases in six main referral/teaching hospitals located in different parts of the country. Consecutive patients visiting the follow-up cardiac clinics of these hospitals from 1 January to 30 June 2015 were included in the study. Data were collected on a pretested questionnaire. RESULTS: A total of 6275 patients (58.5% females) were included in the study. Nearly 61% of the patients were from urban areas. The median age was 33 years (IQR 14-55 years). Valvular heart disease was the most common diagnosis, accounting for 40.5% of the cases. Of 2541 patents with valvular heart disease, 2184 (86%) were cases of chronic rheumatic heart disease. CONCLUSION: Our study shows that chronic rheumatic valvular heart disease is the most common cardiovascular diagnosis among patients seen at cardiology clinics of six referral/teaching hospitals in the country, followed by congenital heart diseases. Hypertensive and ischaemic heart diseases also accounted for a significant proportion of the cases. Therefore, strategies directed towards primary and secondary prevention of acute rheumatic fever as well as prevention of risk factors for hypertension and ischaemic heart disease may need to be strengthened.

Adjunctive dexamethasone therapy in unconfirmed bacterial meningitis in resource limited settings: is it a risk worth taking?

BACKGROUND: Bacterial meningitis is associated with significant morbidity and mortality despite advances in medical care. The main objective of this study was to assess the association of adjunctive dexamethasone treatment with discharge outcome of patients treated as bacterial meningitis in low income setting. METHODS: A retrospective study was conducted at four teaching hospitals across Ethiopia. Patients of age 14 years and older treated as cases of bacterial meningitis between January 1, 2011 and April 30, 2015 were included in this study. Information regarding sociodemographic data, clinical presentations, laboratory data, treatments given and status at hospital discharge were retrieved from patients' medical records using a structured questionnaire. Predefined outcome variables at discharge were analysed using descriptive statistics. Multivariable logistic regression was used to identify factors independently associated with poor outcome. RESULTS: A total of 425 patients treated with the presumptive clinical diagnosis of bacterial meningitis were included in this study (lumbar puncture done in 56 %; only 19 % had CSF findings compatible with bacterial meningitis, and only 3 % had proven etiology). The overall in hospital mortality rate was 20.2 %. Impaired consciousness, aspiration pneumonia, and cranial nerve palsy at admission were independently associated with increased mortality. Adjuvant dexamethasone, which was used in 50.4 % of patients, was associated with increased in-hospital mortality (AOR = 3.38; 95 % CI 1.87-6.12, p < 0.001) and low Glasgow outcome scale (GOS) at discharge (AOR = 4.46 (95 % CI 1.98-10.08). This association between dexamethasone and unfavorable outcome was found to be more pronounced in suspected but unproven cases and in those without CSF alterations compatible with bacterial meningitis. CONCLUSION: Most patients treated for suspected bacterial meningitis did not receive proper diagnostic workup. Adjuvant dexamethasone use in clinically suspected but unproven cases of bacterial meningitis was associated with an increased mortality and poor discharge GOS. These findings show that there are potential deleterious effects in unconfirmed cases in this setting. Physicians practising under such circumstances should thus abide with the current recommendation and defer the use of adjuvant corticosteroid in suspected cases of bacterial meningitis.

Prevalence of rheumatic heart disease among school children in Ethiopia: A multisite echocardiography-based screening.

BACKGROUND: Auscultation-based surveys in Ethiopia conducted in the late 1990's reported a rural prevalence of 4.6/1000 and an urban prevalence of 6.4/1000 of rheumatic heart disease (RHD). With echo-based screening, we aimed to estimate the national prevalence of RHD in school children by taking school-based samples from six regions across the country using the 2012 World Heart Federation echocardiographic criteria. PATIENTS AND METHODS: We conducted a cross-sectional echocardiographic screening of RHD in school children aged 6-18years from 28 randomly selected primary and secondary schools found in six different geographic regions of Ethiopia. We used the standardized WHF echocardiographic criteria. RESULTS: A total of 3238 children (48.5% females) were screened. The mean age was 13.2±3.2years. Of these, 44 patients (1.4%) met the WHF criteria for definite RHD, while 15 (0.5%) met the criteria for borderline disease, yielding a prevalence of 19 [13.9-23.4, 95% CI] cases per 1000 school children between the ages of 6-18years. The majority of those who tested positive were girls (26/44). The prevalence was lowest in children aged 6-9years and otherwise uniformly distributed across ages 10-18years. Definite RHD involved the mitral valve in 42 subjects, 39 of whom had mitral regurgitation and 3 with mitral stenosis. The aortic valve was affected in 6 children. The ratio of definite to borderline cases was 2.9. CONCLUSION: This study demonstrated a consistent pattern of high prevalence of asymptomatic RHD with definite disease predominating over borderline involvement across six regions of Ethiopia.

Challenges of bacterial meningitis case management in low income settings: an experience from Ethiopia.

OBJECTIVE: To investigate the current diagnostic and therapeutic strategies used in the care of patients with suspected bacterial meningitis at teaching hospitals in Ethiopia. METHODS: This was a hospital-based retrospective study conducted at four teaching hospitals in different regions of Ethiopia. Participants were patients aged 14 years and older treated for suspected bacterial meningitis. Presenting complaints, diagnostic strategies used and treatments given were obtained from clinical records. RESULT: A total of 425 patients were included in the study; 52.7% were men and 83.8% were younger than 50 years. Fever, headache, neck stiffness and impaired consciousness were the most common clinical presentations; 55.5% underwent lumbar puncture. Overall, only 96 (22.6%) patients had cerebrospinal fluid abnormalities compatible with bacterial meningitis. A causative bacterium was identified in only 14 cases. Ceftriaxone was used as the empiric treatment of choice, either alone or in combination with other antibiotics; 17.6% of patients were also given vancomycin. Adjunctive dexamethasone was given to 50.4%. CONCLUSION: Most patients treated as bacterial meningitis did not receive a proper diagnostic workup. The choice of antibiotic was not tailored to the specific clinical condition of the patient. Such an approach may result in poor treatment outcomes and lead to antibiotic resistance. Management of patients with suspected bacterial meningitis should be supported by analysis of cerebrospinal fluid, and treatment should be tailored to local evidence and current evidence-based recommendations.

Syphilis among people with HIV infection in southern Ethiopia: sero-prevalence and risk factors.

BACKGROUND: Syphilis facilitates both HIV (human immunodeficiency virus) transmission and acquisition, reflecting the complex interplay between the two infections. Scarce information exists regarding syphilis epidemiology in Ethiopian context. Thus, this study determined the sero-prevalence of syphilis and associated risk factors in people with HIV infection. METHODS: A cross-sectional study was conducted at Hawassa Referral Hospital, southern Ethiopia from January to May, 2014. A consecutive 993 HIV-infected participants were studied; but individuals under 15 years of age or treated for syphilis or those with a CD4+ T-cell count below 50 cells/µl were excluded. Structured questionnaires were used to collect data on socio-demography and potential risk factors for syphilis. Moreover, blood samples were collected from all participants and screened for syphilis using rapid plasma reagin (RPR) test, and those found sero-positive were confirmed using treponema pallidum haemagglutination assay (TPHA). RESULTS: The sero-prevalence of syphilis was found to be 7.3% (95% CI 5.7- 9%). The rate of infection was significantly higher among participants who were ART (antiretroviral therapy) naive (odds ratio (OR) = 2.2; 95% CI 1.22 - 4.1), men (OR = 2.2; 95% CI 1.22 - 3.87), older than 50 years of age (OR = 3.9; 95% CI 1.45 - 6.94), had only primary school level education (OR = 7.8; 95% CI 2.63 - 23.2) and had a history of blood transfusion (OR = 3.9; 95% CI 1.5 - 10.4). CONCLUSION: The high prevalence of syphilis among HIV-infected population warrants integrating syphilis screening with HIV care to limit the clinical consequences of untreated syphilis as well as its adverse impact on HIV transmission.
