RESUMO

Hypoparathyroidism is a rare metabolic disease. In addition to symptoms of hypocalcemia, chronic hypoparathyroidism can result in brain calcifications leading to Fahr syndrome. Hypoparathyroidism most commonly results as a postsurgical complication, with autoimmune disease the second most common etiology. Here we report a 48-year-old man with symptoms of chronic hypocalcemia who presented with status epilepticus following severe coronavirus disease 2019 (COVID-19) infection. In addition to severe hypocalcemia, he was found to have an inappropriately low serum parathyroid hormone level and basal ganglia calcifications visualized on head computed tomography scan. He was treated with intravenous calcium infusion prior to transition to orally administered calcium, calcitriol, and high-dose cholecalciferol (vitamin D3).

RESUMO

Background: Various indigenous medicinal systems including Ethiopians used Cyphostemma adenocaule for managing tumors, helminthiasis, snake envenomation, rabis virus, splenomegaly, and other immunological disorders. However, no scientific study was conducted to validate these traditional medicinal claims of the plant. Therefore, this study aimed to evaluate the in-vivo immunomodulatory activity of the crude root extract and its solvent fractions. Methods: Carbon clearance rate and humoral antibody titer were determined for 100, 200, and 400 mg/kg of crude extract and solvent fractions among Swiss albino mice. Carbon ink and sheep red blood cells were used as antigens for carbon clearance assay and humoral antibody titer respectively. Results: Among all groups, an increase in both carbon clearance rate and the humoral antibody titer was observed with an increase in the dose of both crude extract and solvent fractions. Compared to the solvent fractions of comparable doses, the crude extract showed better activity. The crude extract at a dose of 400 mg/kg revealed the highest and statistically significant augmentation of carbon clearance rate (0.1100 ± 0.0124) and humoral antibody titer (96.00 ± 14.31) compared to the vehicle control group. Conclusion: From our study, it is concluded that crude extract and n-butanol fraction showed promising immunostimulant activity by enhancing carbon clearance rate and humoral antibody titer.

RESUMO

INTRODUCTION: Cyphostemma adenocaule (Steud. ex A. Rich) Descoings ex wild & Drummond (Vitaceae) has been used in traditional medicine for the management of various immunological and hematological disorders in different areas of Ethiopia and the rest of the world. In Ethiopia, the plant is used for the management of enlarged spleen, rabies virus, helminthic infection, snake bite, and various types of tumors. OBJECTIVE: To evaluate the effect of hydroethanolic root extract and solvent fractions of Cyphostemma adenocaule on cell-mediated immunity (delayed-type hypersensitivity), organ index (spleen and liver), and blood cell count in Swiss albino mice. MATERIALS AND METHODS: Acute oral toxicity test was conducted using nulliparous and nonpregnant Swiss albino mice following OECD 425 limit test method. Delayed-type hypersensitivity model was used to evaluate the effect on cell-mediated immunity. The experimental animals were divided into twelve groups which were sensitized and challenged with sheep red blood cells on day 0 and day 7, respectively. Levamisole 50 mg/kg was used as stimulant control, whereas cyclophosphamide 30 mg/kg was used as suppressant control. Hydroethanolic root extract (100 mg/kg, 200 mg/kg, and 400 mg/kg), aqueous fraction (100 mg/kg, 200 mg/kg, and 400 mg/kg), and n-butanol fraction (100 mg/kg, 200 mg/kg, and 400 mg/kg) were administered for seven days. The paw volume was measured using a digital plethysmometer before challenge and 24 hours after challenge. Blood was collected, and organs (spleen and liver) were isolated from each challenged mouse to determine blood cell count and organ index, respectively. RESULTS: No mortality and noticeable behavioral changes were observed among all mice receiving hydroethanolic root extract and solvent fractions at a dose of 2000 mg/kg. Hydroethanolic root extract and solvent fractions of Cyphostemma adenocaule showed enhancement of delayed-type hypersensitivity, organ index, and blood cell count. Hydroethanolic root extract at a dose of 400 mg/kg showed the highest and statistically significant stimulation of delayed-type hypersensitivity (0.123 ± 0.010) and blood cell count compared to the vehicle. CONCLUSION: Hydroethanolic root extract and solvent fractions of Cyphostemma adenocaule showed a stimulatory effect on cell-mediated immunity and hematopoiesis.

RESUMO

BACKGROUND: An umbilical granuloma is one of the common umbilical masses in young children which appears after the cords fall off, mainly due to an inflammatory reaction to subclinical infections. Though there are different recommendations of treatment modalities, which management modality is the best is not clear yet. OBJECTIVE: This systematic review aimed to assess the effectiveness of salt treatment in terms of complete resolution of the granuloma, any adverse effect, and any recurrence risk in those patients treated as inpatient or outpatient care. METHODOLOGY: The literature search was done using search engines including Google scholar, PubMed, and Medlin. Articles published since 1990 and written in the English language with a target population of young children (less than 24 months) were included. To retrieve the articles, umbilical granuloma, treatment of umbilical granuloma, salt treatment, and neonatal umbilical disorder were used as keywords. RESULTS: This systematic review indicated that the majority of the studies done on salt treatment for umbilical granuloma show excellent response (complete resolution of the granuloma/discharge) with no adverse effect and no recurrence in the subsequent follow-up of the patients in almost all cases of the treatment group. Salt inside the occluded hyperosmolar chamber causes shrinkage of granuloma by a desiccant effect. CONCLUSION: Cooking salt treatment for umbilical granuloma is effective, cheap, available, and easy to apply by non-health professionals. No side effects have been reported yet and a recurrence of the granuloma after treatment seems to be null.

RESUMO

Otostegia fruticosa is traditionally used to treat tonsillitis, stomach ache, asthma, arthritis, and febrile illness in different parts of Ethiopia and other countries. In this experiment 70% ethanolic crude extract and fractions of the leaf of Otostegia fruticosa (Forssk.) Schweinf. ex Penzig were evaluated for their in-vivo anti-inflammatory and analgesic activities and in-vitro hyaluronidase inhibition properties at different concentrations. Tail immersion, acetic acid induced writhing and carrageenan-induced paw edema model were used to assess the in-vivo analgesic and anti-inflammatory activities, respectively. Swiss albino mice of either sex were randomly divided into five groups of six mice per group and for evaluation of the fractions randomly divided into six groups of six mice per group. The test groups were treated with hydroalcoholic extract of Otostegia fruticosa (O. fruticosa) at doses of 100, 200, and 400 mg/kg. The positive control groups received either pethidine 5 mg/kg or aspirin at 100 mg/kg or 150 mg/kg. The negative control groups were orally given sunflower oil. All the fractions were administered at the dose of 400 mg/kg. In all models, the higher dose (400 mg/kg) of the crude extract and chloroform fraction showed a significant central and peripheral analgesic and anti-inflammatory activities with comparable effects to standards used. The hyaluronidase inhibition assay result showed that the test samples displayed concentration-dependent inhibitory activities. These findings indicate that 70% ethanol extract and organic solvent fractions of O. fruticosa leaves have potential analgesic, anti-inflammatory, and enzyme inhibitory activities.

RESUMO

Malaria is a major global public health problem caused by Plasmodium parasites. Drug resistance is becoming a great challenge. New drugs with novel mechanism of action are urgently required. In malarious countries, medicinal plants are commonly used for malaria treatment. Olea europaea is traditionally used against malaria in Ethiopia. The aim of this study was to isolate and evaluate antimalarial activity of chemical constituents extracted from Olea europaea against chloroquine-sensitive Plasmodium berghei-infected mice. Stem bark of Olea europaea was extracted with 80% methanol and fractionated with three solvents. The butanol fraction was subjected to isolation with preparative thin-layer chromatography (PTLC). Acute oral toxicity studies were conducted in mice as per the Organization for Economic Co-operation and Development (OECD) guideline 425. Antimalarial activities of the test substances were evaluated using Peter's 4-day suppressive test. The crude extract showed significant (p < 0.01) antiplasmodial activity at all doses with a chemosuppression value of 52.40% at a dose of 600 mg/kg. All fractions also suppressed parasitaemia significantly (p < 0.05), the highest suppression (45.42%) being with butanol fraction. In the phytochemical analysis, two compounds were isolated. Both compounds showed significant (p < 0.05) antimalarial activities. Compound C inhibited parasitaemia up to 38.19% at a dose of 200 mg/kg. The crude extract, butanol fraction, and isolated compounds also prolonged survival time of mice. No sign of toxicity and mortality was seen in the test substances at up to a single dose of 2 g/kg. Findings of the current study may confirm the traditional antimalarial claim of Olea europaea and its relative safety as well as the potentiality of compound C for further investigations.

RESUMO

OBJECTIVES: Early antiretroviral therapy (ART), isoniazid preventive therapy (IPT), and isoniazid-rifapentine (3HP) are effective strategies for preventing tuberculosis (TB) among people living with HIV (PLHIV). The study aimed to determine the effect of IPT on the TB incidence, follow-up CD4+ T cells, and all-cause mortality rate. Participants. Eligible patients on ART (n = 1, 863) were categorized into one-to-two ratios of exposed groups to IPT (n = 621) and nonexposed groups to IPT (n = 1, 242). Exposed groups entered the cohort at their first prescription of IPT, and unexposed groups entered into the study at the first prescription of ART and then followed until the occurrence of the outcome or date of administrative censoring (June 30, 2017). The outcome endpoints were TB incidence, follow-up CD4+ T cells, and all-cause mortality rate. RESULTS: The follow-up CD4+ T cells for the exposed and nonexposed groups were 405.74 and 366.95 cells/mm (World Health Organization (WHO), 2017), respectively, a statistically significant finding (t 1861 = -3.770, p < 0.0001; Cohen's d = 0.186). Nine percent of the exposed patients (620 incidence of TB per 100,000 person-years (PYs)) and 21.9% of the nonexposed patients (3160 incidence of TB per 100,000 PYs) developed TB. Mortality rate (per 100,000 PYs) was 440 for the exposed and 1490 for the unexposed patients. Statistically significant determinants of the all-cause mortality were unscheduled follow-up (AHR = 1.601; 95% CI: 1.154-2.222) and unable to work properly (AHR = 2.324; 95% CI: 1.643-3.288). CONCLUSION: This study demonstrates the effect of IPT in reducing incidence of TB and all-cause mortality rate and improving follow-up CD4+ T cells. Promoting IPT use can help to achieve the TB eradicating national agenda in Ethiopia.

RESUMO

BACKGROUND: The highest prevalence and emergence of microbial infections coupled with the threat of antimicrobial resistance constitute a global concern, which entails searching for novel antimicrobial agents. Medicinal plants are among the major sources of medicines for novel drug discovery. Aloe adigratana is one of the endemic Aloe species in Ethiopia where the leaf latex of the plant is traditionally used for the treatment of various pathogenic conditions such as wound, dandruff, malaria, and diabetes. In spite of such claims, there was no scientific study done so far. The aim of the current study was, therefore, to evaluate the antimicrobial effect of leaf latex of A. adigratana and its thin layer chromatography (TLC) fractions. METHODS: Thin layer chromatography (TLC) separation was employed for isolation of bioactive compounds. Agar well diffusion and microdilution assay method were used to evaluate the antimicrobial actions of the leaf latex and TLC fractions against six bacterial strains and four Candida species of reference and clinical isolate microbial strains. RESULTS: Three major fractions, AA01, AA02, and AA03, were identified by TLC. Among the tested microbial strains, the reference strain of Staphylococcus aureus ATCC 29213 (MIC = 0.06 mg/mL) and clinical Candida krusei 242/18 (MIC = 0.14 mg/mL) exhibited higher susceptibility towards AA02, while reference strains of Klebsiella pneumoniae ATCC 700603 (MIC = 0.19 mg/mL) revealed the highest susceptibility towards AA01. The leaf latex displayed the highest activity against Staphylococcus aureus ATCC 29213 and clinical Candida krusei 242/18 with a MIC value of 0.19 mg/mL. CONCLUSION: The leaf latex and TLC fractions were found to be active against the tested bacterial and Candida species. Therefore, this finding supports the traditional claim of Aloe adigratana and the need for characterization of the TLC fractions to provide as lead compounds for further comprehensive antibacterial and antifungal activities.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Capparis tomentosa Lam. root is one of the commonly used traditional medicines for the treatment of pain and inflammatory conditions by the Kunama ethnic group of Ethiopia. Yet, its ethnomedicinal claim has not been scientifically investigated. AIM OF THE STUDY: This study aims to evaluate the anti-inflammatory and anti-nociception activities of root extracts of Capparis tomentosa Lam. MATERIALS AND METHODS: The anti-inflammatory activity of the 70% ethanolic extracts and solvent fractions was determined using invitro hyaluronidase inhibition assay and in vivo carrageenan-induced paw edema in Swiss albino mice model. The anti-nociception effect was determined using the acetic acid-induced writhing model and tail immersion model in Swiss albino mice. RESULTS: The root extract of Capparis tomentosa has exhibited significant hyaluronidase inhibition activity which was comparable with the reference drug, indomethacin. Significant inhibition of carrageenan-induced paw edema was observed in all the test sample treated mice compared to the negative control with the highest activity observed from butanol fraction which was equivalent to the effect of acetylsalicylic acid. All the root extract and solvent fractions have possessed a significant and dose-dependent abdominal writhing inhibition with the highest effect observed in the aqueous fraction. Additionally, the crude extract was found better in increasing the reaction latency of the mice to the hot water stimulus than the solvent fractions which were significant after 60-120 min compared to the distilled water treated group. The root extract and solvent fractions were also found safe at a single oral dose of 2 mg/g in Swiss albino mice. CONCLUSION: The findings of the present study may partially support the folkloric use of Capparis tomentosa root for the treatment of pain and inflammation.

RESUMO

The genus Echinops belongs to the family of Asteraceae and comprises about 130 species. Many species belonging to the genus Echinops are traditionally used as medicinals mainly in Africa and Asia. The genus is reported to contain diverse secondary metabolites. The aim of this review is to critically evaluate the available research reports on the genus and systematically organize the findings. Information for this study was obtained using various search engines including PubMed and Google Scholar. This review revealed that the genus is used traditionally to treat pain, inflammation, respiratory diseases, diseases caused by different microorganisms, as an aphrodisiac, to fasten expulsion of placenta, and for removal of renal stones. More than 151 secondary metabolites have been reported from the genus in which thiophenic compounds held the biggest share. Various extracts, essential oils, and isolated compounds from members of this genus are shown to exhibit different biological effects mainly anti-microbial, anti-proliferative, and anti-inflammatory. However, there are a number of species in this genus that are claimed to have traditional medicinal uses but their biological effect not yet been evaluated.

RESUMO

OBJECTIVES: Urinary tract infections (UTIs) are one of the most common infections in humans. Studies have shown that antibiotics for UTIs are usually prescribed empirically before the results of urine culture are available. The aim of the study was to assess the antimicrobial resistance patterns of bacteria isolated from urine samples over 6 years in Ayder Comprehensive Specialized Hospital (ACSH), in Mekelle, Northern Ethiopia. METHODS: A retrospective study of culture results of UTI samples was conducted in ACSH from January 2012 to December 2017. Data were collected using a structured data sheet format and were analysed using SPSS v.20.0. RESULTS: Among 1080 urine samples tested during the 6-year period, 308 (28.5%) were positive for bacterial isolates. The majority of participants were female (57.8%). The three most commonly isolated bacteria were Escherichia coli (48.1%), Klebsiella pneumoniae (16.2%) and Pseudomonas aeruginosa (6.5%). Escherichia coli was found to be most susceptible to imipenem (100%) and most resistant to ampicillin (94.9%). Similarly, K. pneumoniae was sensitive to meropenem (100%) but resistant to penicillin (100%). Multidrug resistance to two or more antimicrobials was observed in 267 isolates (86.7%), with a non-significantly higher prevalence in females (χ2=9.65, P=0.29). The overall pooled bacterial resistance was 57.8%. CONCLUSION: This study revealed that most of the urine isolates showed high levels of antimicrobial resistance to commonly prescribed antibiotics although they remained susceptible to imipenem, nitrofurantoin and meropenem. The results call for continuous surveillance of antimicrobial resistance for better management of patients with UTIs.

RESUMO

Background: There are rich knowledge and practice in Ethiopian traditional medicine of using plants for the treatment of various ailments, including wounds. Though scholars have been working on documenting the ethnobotanical use of plants, the studies are still ongoing. Objectives: This study systematically reviewed medicinal plants traditionally employed for the treatment of wounds in Ethiopia. Methods: A systematic review of the literature was conducted using PubMed and Google Scholar; a search of grey literature was also carried out as part of the review. Search terms and phrases included 'traditional medicine', 'ethnomedicine', 'ethnobotany' and 'Ethiopia'. Data regarding the scientific name, family, local name, growth form of the plant, mode of administration, and availability of voucher specimen were extracted. Results: Based on the eligibility criteria, 29 studies were retrieved from PubMed, and 25 from Google Scholar and the grey literature. Around 200 medicinal plants which are used to treat wounds in Ethiopian traditional medicine were recorded. Leaves and roots were the most commonly used plant parts to treat wounds, while shrubs and herbs were reported to be the growth forms of most plants. The mode of administration was topical in almost all cases. Conclusions: Medicinal plants have been used extensively to treat wounds in Ethiopia. Nevertheless, the scientific exploration of plants' efficacy and safety is inadequate, and relevant activity studies ought to be conducted to provide scientific evidence to the traditional claims of these plants

RESUMO

BACKGROUND: Antimicrobial drug resistance is a global threat for treatment of infectious diseases and costs life and money and threatens health delivery system's effectiveness. The resistance of E. coli to frequently utilized antimicrobial drugs is becoming a major challenge in Ethiopia. However, there is no inclusive countrywide study. Therefore, this study intended to assess the prevalence of E. coli resistance and antimicrobial-specific resistance pattern among E. coli clinical isolates in Ethiopia. METHODS: Articles were retrieved from PubMed, Embase, and grey literature from 2007 to 2017. The main outcome measures were overall E. coli and drug-specific resistance patterns. A random-effects model was used to determine pooled prevalence with 95% confidence interval (CI), using DerSimonian and Laird method. In addition, subgroup analysis was conducted to improve the outcome. The study bias was assessed by Begg's funnel plot. This study was registered in PROSPERO as follows: PROSPERO 2017: CRD42017070106. RESULTS: Of 164 articles retrieved, 35 articles were included. A total of 19,235 study samples participated in the studies and 2,635 E. coli strains were isolated. Overall, E. coli antibacterial resistance was 45.38% (95% confidence interval (CI): 33.50 to 57.27). The resistance pattern ranges from 62.55% in Addis Ababa to 27.51% in Tigray region. The highest resistance of E. coli reported was to ampicillin (83.81%) and amoxicillin (75.79%), whereas only 13.55% of E. coli isolates showed resistance to nitrofurantoin. CONCLUSION: E. coli antimicrobial resistance remains high with disparities observed among regions. The bacterium was found to be highly resistant to aminopenicillins. The finding implies the need for effective prevention strategies for the E. coli drug resistance and calls for multifaceted approaches with full involvement of all stakeholders.

RESUMO

Malaria is one of the world's most severe endemic diseases and due to the emergence of resistance to the currently available medicines, the need for new targets and relevant antimalarial drugs remains acute. The crude extract, four solvent fractions and two isolated compounds from the roots of Echinops hoehnelii were tested for their antimalarial activity using the standard four-day suppressive method in Plasmodium berghei-infected mice. The 80% methanol extract exhibited suppression of 4.6%, 27.8%, 68.5% and 78.7% at dose of 50, 100, 200 and 400 mg/kg respectively. The dichloromethane fraction displayed chemosuppression of 24.9, 33.5 and 43.0% dose of 100, 200 and 400 mg/kg of body weight. Five acetylenicthiophenes were isolated from the dichloromethane fraction of which 5-(penta-1,3-diynyl)-2-(3,4-dihydroxybut-1-ynyl)-thiophene decreased the level of parasitaemia by 43.2% and 50.2% while 5-(penta-1,3-diynyl)-2-(3-chloro-4-acetoxy-but-1-yn)-thiophene suppressed by 18.8% and 32.7% at 50 and 100 mg/kg, respectively. The study confirmed the traditional claim of the plant to treat malaria and could be used as a new lead for the development of antimalarial drugs.
