RESUMO
Until now, no specific and effective treatment exists for coronavirus disease 2019 (COVID-19). Since honey and Nigella sativa (HNS) have established antiviral, antibacterial, antiinflammatory, antioxidant, and immunomodulatory properties, we tested their efficacy for this disease in a multicenter, placebo-controlled, and randomized clinical trial at four medical care facilities in Pakistan. RT-PCR confirmed COVID-19 adults showing moderate or severe disease were enrolled in the trial. Patients were randomly assigned in a 1:1 ratio to receive either honey (1 g kg-1 day-1 ) and Nigella sativa seeds (80 mg kg-1 day-1 ) or a placebo for up to 13 days along with standard care. The outcomes included symptoms' alleviation, viral clearance, and 30-day mortality in the intention-to-treat population. Three hundred and thirteen patients, 210 with moderate and 103 with severe disease, underwent randomization from April 30 to July 29, 2020. Among the moderate cases, 107 were assigned to HNS, whereas 103 were assigned to the placebo group. Among the severe cases, 50 were given HNS, and 53 were given the placebo. HNS resulted in ~50% reduction in time taken to alleviate symptoms as compared to placebo (moderate cases: 4 vs. 7 days, Hazard Ratio [HR]: 6.11; 95% Confidence Interval [CI]: 4.23-8.84, p < 0.0001 and for severe cases: 6 vs. 13 days, HR: 4.04; 95% CI: 2.46-6.64; p < 0.0001). HNS also cleared the virus earlier than placebo in both moderate cases (6 vs. 10 days, HR: 5.53; 95% CI: 3.76-8.14, p < 0.0001) and severe cases (8.5 vs. 12 days, HR: 4.32; 95% CI: 2.62-7.13, p < 0.0001). HNS further led to a better clinical score on day 6 with normal activity resumption in 63.6% vs. 10.9% among moderate cases (OR: 0.07; 95% CI: 0.03-0.13, p < 0.0001) and hospital discharge in 50% versus 2.8% in severe cases (OR: 0.03; 95% CI: 0.01-0.09, p < 0.0001). In severe cases, the mortality rate was less than 1/4th in the HNS group than in placebo (4% vs. 18.87%, OR: 0.18; 95% CI: 0.02-0.92, p = 0.029). No HNS-related adverse effects were observed. HNS, compared with placebo, significantly improved symptoms, expedited viral load clearance, and reduced mortality in COVID-19 patients. This trial was registered on April 15, 2020 with ClinicalTrials.gov Identifier: NCT04347382.

BACKGROUND: Irrational use of antibiotics intensifies resistance and jeopardizes advances made in modern medicine. We aimed to conduct a baseline gap analysis survey on antibiotic prescription practices across Pakistan. RESEARCH DESIGN AND METHODS: This multi-centered cross-sectional survey was conducted at six public sector tertiary care hospitals from February 2021 to March 2021. Data related to various variables including hospital infrastructure, policies and practices, monitoring and feedback, and epidemiological, clinical, and antibiotic prescription for surveyed patients was collected using World Health Organization (WHO) Point Prevalence Survey (PPS) methodology. RESULTS: In a survey of 837 inpatients, 78.5% were prescribed antibiotics. Most commonly prescribed antimicrobial was ceftriaxone (21.7%), followed by metronidazole (17.3%), cefoperazone-sulbactam (8.4%), amoxicillin-clavulanate (6.3%), and piperacillin/tazobactam (5.9%). Surgical prophylaxis (36.7%) and community-acquired infections (24.7%) were the main reasons for antibiotic prescriptions. Single antibiotics were given to 46.7% of patients, 39.9% received a combination of two antibiotics, and 12.5% were prescribed three or more antibiotics. Among six hospitals surveyed, two had drug and therapeutic committees, three had infection prevention and control committees, and one had an antibiotic formulary. CONCLUSION: Findings demonstrate high consumption of broad-spectrum antimicrobials and emphasize the importance of expanding antimicrobial stewardship programs among hospitals. Mentoring clinical teams could help rationalize antimicrobial use.
RESUMO
BACKGROUND: Peripheral Arterial Disease [PAD], a manifestation of systemic atherosclerosis, is highly prevalent both in community studies and in primary care practice. Estimation of ankle brachial index [ABI] by ultrasound Doppler is the standard screening method for the detection of atherosclerosis in PAD patients. A low ABI is associated with increased risk of stroke or transient ischemic attack, ischemic heart disease and lower extremity gangrene. Though prevalence is high, physician and patient awareness of the condition is low. Primary care physicians are not well versed with the use of Doppler. Initial cost of the equipment is another adverse factor in low income countries. Detection of ankle systolic pressure by palpatory method may offer a cheap, simple and useful alternative approach in office care settings for early detection of disease. This may lead to the use of risk reduction strategies to avoid significant future morbidity and mortality. METHODS: The sample size of 230 participants was identified. Patients were divided into control (100 cases), high risk asymptomatic (100 cases) and symptomatic groups (30 cases). Ankle systolic pressure was measured by digital palpation of foot arteries and by the gold standard Doppler technique in all patients in the three groups. PAD was defined by an ABI of < 0.9. RESULTS: In control group, mean +/- SD value of ABI was 1.0115 +/- 0.08167 by Doppler method versus 0.9923 +/- 0.08609 by palpatory method (p = 0.1), in high risk asymptomatic group, 0.9838 +/- 0.08878 versus 0.9608 +/- 0.10377 (p = 0.13) and in symptomatic group, 0.9302 +/- 0.14064 versus 0.9088 +/- 0.13274 (p = 0.12). Against the more precise Doppler method, palpatory method was equally good in detecting the PAD positive cases. CONCLUSION: Early diagnosis of PAD in primary care practice by manual palpation of foot arteries is a reliable method to identitfy the population at risk and may lead to aggressive preventive therapies.

OBJECTIVE: To evaluate the plasma interleukin-10 (IL-10) levels in patients suffering from dengue hemorrhagic fever between 4 to 7 days of onset of disease and 24 hours after the first sample, to find out the association of plasma IL-10 levels with the outcome. STUDY DESIGN: Analytical study. PLACE AND DURATION OF STUDY: All major hospitals of Lahore, Pakistan, from August to November 2012. METHODOLOGY: Participants included 50 registered patients of dengue hemorrhagic fever (DHF) aged between 15 - 50 years. Plasma IL-10 concentrations were measured on above stated day. Outcome was described as recovery and shock. Platelet count and hematocrit percentages were also recorded. Statistical analyses were done using SPSS version 19. Ap-value ≤0.05 was considered significant. RESULTS: Plasma IL-10 levels were found to be raised in DHF patients and were associated with fatal outcome (p=0.004). In recovered DHF patients, plasma IL-10 levels decreased after 24 hours (mean 26.54 ± 16.03 pg/ml) as compared to admission time (mean 74.39 ± 61.69 pg/ml) but in case of DHF patients suffering from shock, plasma IL-10 was found to be higher after 24 hours (mean 87.69 ± 7.77 pg/ml) as compared to levels at admission time (mean 42.56 ± 28.09 pg/ml). ROC curve analysis revealed a change (30 units pg/ml) of plasma IL-10 concentration, within 24 hours of admission, raised from the base line to be 105 times more critical for shock in DHF patients (100% sensitivity and 71.4% specificity, p < 0.001). CONCLUSION: Elevated plasma IL-10 is a potential predictor of disease severity and fatal outcome in DHF patients.

OBJECTIVE: To compare serum 25-hydroxy vitamin D level between preeclamptic and normotensive pregnancies. STUDY DESIGN: Cross-sectional analytical study. PLACE AND DURATION OF STUDY: Department of Physiology, Federal Postgraduate Medical Institute, Shaikh Zayed Hospital, Lahore, in collaboration with Sir Ganga Ram Hospital and Lady Willingdon Hospital, Lahore, from March 2012 to April 2012. METHODOLOGY: Thirty registered preeclamptic patients with systolic and diastolic blood pressure > 140/90 mm Hg on more than two occasions, 6 hours apart, and proteinuria at least 300 mg in 24-hour urine collection; and 30 normotensive uncomplicated pregnant women matched for age, gestational age, parity and BMI were included by convenient sampling technique. Vitamin D levels of less than 50 n mol/l (< 20 ng/ml) was the cutoff point. Spearman's rank correlation of vitamin D with systolic blood pressure and arterial pressure in both preeclamptic and normotensive pregnant women was presented in a tabulated form. RESULTS: Vitamin D deficiency was found in 95% of preeclamptic and normotensive pregnant women. The difference of vitamin D level between the two groups was not found significant. Although there was an inverse correlation between serum vitamin D and systolic blood pressure and arterial pressure in preeclamptic group, but this was not statistically significant. CONCLUSION: Vitamin D deficiency does not seem to be affected by the state of preeclamptic and normotensive pregnancy. The correlation of systolic blood pressure and arterial pressure and vitamin D needs to be explored further by increasing the sample size.

Introduction: This study compared the levels of salivary cortisol in patients suffering from severe depression and in healthy individuals. Methods: Sample size included 30 diagnosed cases of major depression based on outdoor clinical assessment (from April 2015 to December 2105) and was established by ICD-10 and DSM-IV criteria and 30 physically and mentally healthy subjects. In this study diagnosed cases of hyperaldosteronism, Cushing’s syndrome/ disease were omitted. A predesigned proforma was created on the basis of Becks Inventory. Saliva samples were collected and processed, and the measurement of cortisol levels was done by ELISA. Results: In a normal subject, the mean cortisol level was 1.46 ± 0.9 μg/dl (Mean ± SD) whereas in depressive patients it was raised (2.2 ± 1.6 μg/dl, p=0.031). Results also showed that high level of cortisol in saliva was found in individuals with a positive family history of depression (2.3 ± 1.8 μg/dl) as compared to healthy subjects (1.5 ± 1.0 μg/dl). Mean BMI was also found to be different between the 2 groups (p=0.012). Conclusion: We concluded that salivary cortisol may act as an early diagnostic tool and non-invasive biomarker for prompt diagnosis of potential cases of depression for effective management. Hence, early initiation of treatment can be helpful in improving the late clinical consequences in severely depressed patients and decreasing the morbidity.
