Ivermectin is an antiparasitic drug being investigated for repurposing to SARS-CoV-2. In-vitro, ivermectin showed limited antiviral activity and a COVID-19 animal model demonstrated pathological benefits but no effect on viral RNA. This meta-analysis investigated ivermectin in 18 randomized clinical trials (2282 patients) identified through systematic searches of PUBMED, EMBASE, MedRxiv and trial registries. Ivermectin was associated with reduced inflammatory markers (C-Reactive Protein, d-dimer and ferritin) and faster viral clearance by PCR. Viral clearance was treatment dose- and duration-dependent. In six randomized trials of moderate or severe infection, there was a 75% reduction in mortality (Relative Risk=0.25 [95%CI 0.12-0.52]; p=0.0002); 14/650 (2.1%) deaths on ivermectin; 57/597 (9.5%) deaths in controls) with favorable clinical recovery and reduced hospitalization. Many studies included were not peer reviewed and meta-analyses are prone to confounding issues. Ivermectin should be validated in larger, appropriately controlled randomized trials before the results are sufficient for review by regulatory authorities.
Introduction:The current guidelines for the diagnosis of pulmonary tuberculosis (PTB) are based primarily on the demonstration of acid-fast bacilli (AFB) on sputum microscopy and chest radiograph. Knowing various radiological manifestations and their association with sputum microscopy findings can allow for early diagnosis and early initiation of treatment.Aims:This study was performed to compare the chest radiograph features seen in sputum-positive and sputum-negative tuberculosis patients, respectively.Materials and Methods:It was a prospective observational study, which included 147 consecutive patients newly diagnosed and treated as PTB between Jan 2018 and July 2018. Chest X-ray was reviewed by 2 independent radiologists and the findings were compared between sputum-positive and sputum-negative PTB cases. The obtained data were analyzed by statistics using SPSS version 15 for Windows (SPSS Inc., Chicago, IL) and χ2 test and Student t test were used for statistical analysis. P values < 0.05 were considered statistically significant.Results:Out of a total of 147 patients, 38 (25 males and 13 females, mean age 35.23 ± 18.40) were sputum positive and 109 (77 males and 32 females, mean age 36.07 ± 18.15) were sputum negative. The frequency of patchy consolidation (78.94% vs 49.54%) and cavitation (36.84% vs 15.59%) was significantly higher in sputum-positive PTB (P < 0.05). Radiological lesions like nodular shadow (10.09% vs 2.63%), cystic lesion (13.76% vs 5.26%), fibrosis (12.84% vs 7.89%), miliary shadows (2.75% vs 2.63%), and pleural effusion (1.83% vs 0%) were seen more commonly with sputum-negative PTB but the difference was not statistically significant for any of these features. Sputum-positive PTB tends to occur more commonly on the left side (47.36%) compared with sputum-negative PTB (27.52%) (P < 0.05). 34.21% and 35.77% of the chest X-ray lesions were bilateral in sputum-positive and sputum-negative PTB, respectively.Conclusion:Patchy infiltration and cavitation on chest X-ray are seen more frequently in sputum-positive cases of PTB compared with sputum-negative cases.
Melioidosis, a disease with protean clinical manifestations, is prevalent in many parts of India, with established endemic hotspots on the southern coast of the country. However, it is still underdiagnosed in many resource-poor regions of the country. We report what is, to the best of our knowledge, the first case of melioidosis diagnosed and treated in Bihar, an economically underdeveloped state in East India. The patient, a 52-year-old diabetic male, presented to the outpatient department with a fever of insidious onset along with pain and restriction of movement in the right shoulder joint and right knee joint, and swelling and tenderness of bilateral ankle joints. Radiological features were suggestive of multiple joint and organ abscesses. A diagnosis of disseminated septicaemic melioidosis was confirmed microbiologically. The patient improved clinically following aggressive treatment with meropenem and cotrimoxazole. The case highlights the need for increased clinical suspicion of melioidosis and adequate diagnostic facilities, as well as the need for early institution of appropriate empirical antibiotics in suspected cases of melioidosis in this region of the world.
Strongyloidiasis is a common disease worldwide, has a complex life cycle and infect humans percutaneously. We report case of 46-year-old woman, presented with complaints of abdominal pain, and distension. She was on PPI (Proton Pump Inhibitors) for recurrent gastritis. She also gives history of steroid intake for joint pain. USG abdomen showed moderate ascites. Upper GI endoscopy showed diffuse erythematous gastric mucosa with subtle mosaic pattern and edematous duodenal mucosa showing patchy erythema. Histopathological examination of gastric biopsy showed infestation by Strongyloides stercoralis, the gastric mucosal glands contained various parts of parasite. The patient recovered completely after course of antihelmintic drug.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
