RESUMEN
BACKGROUND: The landscape of Pseudomonas infective endocarditis (IE) is evolving with the widespread use of cardiac implantable devices and hospital-acquired infections. This systematic review aimed to evaluate the emerging risk factors and outcomes in Pseudomonas IE. METHODS: A literature search was performed in major electronic databases (PubMed, Scopus, and Google Scholar) with appropriate keywords and combinations till November 2023. We recorded data for risk factors, diagnostic and treatment modalities. This study is registered with PROSPERO, CRD42023442807. RESULTS: A total of 218 cases (131 articles) were included. Intravenous drug use (IDUs) and prosthetic valve endocarditis (PVE) were major risk factors for IE (37.6% and 22%). However, the prosthetic valve was the predominant risk factor in the last two decades (23.5%). Paravalvular complications (paravalvular leak, abscess, or pseudoaneurysm) were described in 40 cases (18%), and the vast majority belonged to the aortic valve (70%). The mean time from symptom onset to presentation was 14 days. The incidence of difficult-to-treat resistant (DTR) pseudomonas was 7.4%. Valve replacement was performed in 57.3% of cases. Combination antibiotics were used in most cases (77%), with the aminoglycosides-based combination being the most frequently used (66%). The overall mortality rate was 26.1%. The recurrence rate was 11.2%. Almost half of these patients were IDUs (47%), and most had aortic valve endocarditis (76%). CONCLUSIONS: This review highlights the changing epidemiology of Pseudomonas endocarditis with the emergence of prosthetic valve infections. Acute presentation and associated high mortality are characteristic of Pseudomonas IE and require aggressive diagnostic and therapeutic approach.
RESUMEN
Enteric fever is a major contributor to rising health care costs in developing countries. Associated disease-related complications and drug resistance further compound this problem. Hemophagocytic lymphohistiocytosis (HLH) is an uncommon complication of enteric fever with high morbidity and mortality. This systematic review aimed to evaluate the clinical characteristics and treatment outcomes in enteric fever-associated HLH syndrome. We searched major electronic databases (PubMed, Google Scholar, and Scopus) to identify the cases of enteric fever associated with HLH from inception until June 2023. Prespecified data regarding clinical presentation, outcomes, and HLH therapy were collected. A total of 53 cases of enteric fever with HLH were included in the final analysis. The mean age of patients was 20 years, and the proportions of female and pediatric patients were 52.8% and 45.3%, respectively. The mean duration of illness was 10.4 days. A total of 39.6% of patients had enteric fever-associated complications; coagulopathy and encephalopathy were the most common (23.1% and 13.5%). The overall mortality rate was 9.4% in HLH. A total of 51% of patients received HLH-specific therapy (corticosteroids in 41.5% and intravenous immunoglobulin in 20.8% of patients). On multivariate analysis, high ferritin levels (≥5,000 ng/mL) were significantly associated with mortality (hazard ratio, 3.01; 95% CI = 0.62-14.12, P = 0.041). Enteric fever with secondary HLH is associated with high mortality. This review reveals the potential role of ferritin in disease prognosis. In cases with significantly elevated ferritin levels, the role of immunosuppressants or combination antibiotics should be explored.

Introduction: Gram-positive bloodstream infections (BSIs) are an emerging health concern, especially in resource-limited settings. There is a paucity of data regarding the antimicrobial resistance (AMR) pattern of Gram-positive BSIs. The rise in multidrug-resistant infections further convoluted antibiotic selection. We aimed to assess the incidence, clinical and microbiological profile, antimicrobial resistance (AMR) and outcome in Gram-positive BSIs. Methods: This was a single-center prospective study conducted at a tertiary care hospital in Western India. All patients (age ≥18 years) with culture-proven Gram-positive BSIs were included. Data were collected on all patients' demography, risk factors, AMR and clinical outcome. Results: A total of 210 clinically significant isolates were grown from July 2020 to December 2021. The incidence of Gram-positive BSIs was 29% (n=61); 55.9% of cases were healthcare-associated, while 44.1% were community-acquired. Coagulase-negative staphylococci (CoNS) were the major isolates (36.1%), followed by Enterococcus spp. (27.9%), methicillin-susceptible Staphylococcus aureus (MSSA) (18%) and methicillin-resistant Staphylococcus aureus (MRSA) (14.7%). The proportion of vancomycin and teicoplanin-resistant CoNS isolates was 13.6% and 19%. Among Enterococcus isolates, the proportion of vancomycin-resistant enterococci (VRE) and linezolid-resistant enterococci (LRE) were 11.8% and 5.9%. The overall mortality in Gram-positive BSIs was 42.6%. Older age, MRSA infection, septic shock, and high NLR were significantly associated with mortality. On the Cox regression model, age ≥65 years (HR: 2.5; 95%CI: 1.1-5.8; p=0.024) and MRSA infection (HR: 3.6; 95%CI: 1.5-8.5; p=0.021) were found as independent predictors of 30-day mortality. Conclusions: This study found substantial mortality with Gram-positive BSIs, especially MRSA infections. Moreover, the emergence of VRE and LRE is also alarming. Active surveillance of AMR and evaluation of mortality predictors may help overcome the therapeutic challenges in managing BSIs.
RESUMEN
BACKGROUND: CNS manifestations represent an emerging facet of NTM infection with significant mortality. Due to protean presentation and low index of suspicion, many cases are often treated erroneously as tubercular meningitis or fungal infections. OBJECTIVES: Literature on NTM CNS disease is scarce, with most available data on pulmonary disease. This systematic review aimed to evaluate the epidemiology, clinical presentation, diagnostic modalities, and predictors of outcome in CNS NTM infection. METHODS: The literature search was performed in major electronic databases (PubMed, Google Scholar, and Scopus) using keywords "CNS," "Central nervous system," "brain abscess," "meningitis," "spinal," "Nontuberculous mycobacteria," "NTM". All cases of CNS NTM infection reported between January 1980 and December 2022 were included. RESULTS: A total of 77 studies (112 cases) were included in the final analysis. The mean age of all patients was 38 years, with most patients male (62.5%). Mycobacterium avium complex (MAC) was the most common aetiology, followed by M. fortuitum and M. abscessus (34.8%, 21.4% and 15.2%, respectively). The disseminated disease was found in 33% of cases. HIV (33.9%) and neurosurgical hardware (22.3%) were the common risk factors. Intracranial abscess (36.6%) and leptomeningeal enhancement (28%) were the most prevalent findings in neuroimaging. The overall case fatality rate was 37.5%. On multivariate analysis, male gender (adjusted OR 2.4, 95% CI 1.2-7.9) and HIV (adjusted OR 3.7, 95% CI 1.8-6.1) were the independent predictors of mortality). M. fortuitum infection was significantly associated with increased survival (adjusted OR 0.18, 95% CI (0.08-0.45), p value 0.012). CONCLUSIONS: Current evidence shows the emerging role of rapid-grower NTM in CNS disease. Male gender and HIV positivity were associated with significant mortality, while M fortuitum carries favourable outcomes.
RESUMEN
INTRODUCTION: Carbapenem resistant gram-negative bacterial infections are a growing concern worldwide. However, India is already in the era of a shortage of effective antibiotics for the management of these infections. Moreover, Difficult-to-Treat Resistance (DTR) gram-negative infections, which are not much studied, further complicate the scenario. This study emphasized the incidence and outcomes of DTR infections. METHODOLOGY: This is a single-center prospective observational study. The study included hospitalised patients aged ≥18 years with gram-negative bacterial bloodstream infections (GNBSI). Blood cultures with the growth of contaminants and/or single positive culture taken from the femoral site were excluded. Incidences of DTR infections and outcomes in the form of 30-day mortality were analysed. RESULTS: Two hundred forty patients with GNBSI episodes were recorded. The Incidence of DTR GNBSI was 37.9% (91/240). Multivariate analysis found that Hospital-acquired infections, ICU admission and mechanical ventilation were independent risk factors for DTR GNBSI. The most common DTR GNB isolates were Klebsiella pneumoniae (31/49, 63.3%) and Acinetobacter baumannii (26/52, 50%). The adjusted relative risk of mortality was remarkably high in DTR GNBSI (aRR 3.9; 95% CI 1.9-7.9) as compared to CR+/DTR- GNBSI (aRR 0.3; 95% CI 0.1-1.0) and ESCR/CS GNBSI (aRR 1.1; 95% CI 0.5-2.4). CONCLUSION: DTR GNB infections are growing concern in India and this need to be evaluated in multicentric studies. Moreover, DTR GNBSI was associated with significantly higher mortality and there is need of further empowerment of antibiotic stewardship practices.

BACKGROUND: CNS actinomycosis is a rare chronic suppurative infection with non-specific clinical features. Diagnosis is difficult due to its similarity to malignancy, nocardiosis and other granulomatous diseases. This systematic review aimed to evaluate the epidemiology, clinical characteristics, diagnostic modalities and treatment outcomes in CNS actinomycosis. METHODS: The major electronic databases (PubMed, Google Scholar, and Scopus) were searched for the literature review by using distinct keywords: "CNS" or "intracranial" or "brain abscess" or "meningitis" OR "spinal" OR "epidural abscess" and "actinomycosis." All cases with CNS actinomycosis reported between January 1988 to March 2022 were included. RESULTS: A total of 118 cases of CNS disease were included in the final analysis. The mean age of patients was 44 years, and a significant proportion was male (57%). Actinomycosis israelii was the most prevalent species (41.5%), followed by Actinomyces meyeri (22.6%). Disseminated disease was found in 19.5% of cases. Most commonly involved extra-CNS organs are lung (10.2%) and abdomen (5.1%). Brain abscess (55%) followed by leptomeningeal enhancement (22%) were the most common neuroimaging findings. Culture positivity was found in nearly half of the cases (53.4%). The overall case-fatality rate was 11%. Neurological sequelae were present in 22% of the patients. On multivariate analysis, patients who underwent surgery with antimicrobials had better survival (adjusted OR 0.14, 95% CI 0.04-0.28, p value 0.039) compared to those treated with antimicrobials alone. CONCLUSION: CNS actinomycosis carries significant morbidity and mortality despite its indolent nature. Early aggressive surgery, along with prolonged antimicrobial treatment is vital to improve outcomes.

PURPOSE: Invasive cerebral aspergillosis (ICA) is a rare but fatal infection affecting neutropenic immunocompromised patients. Recently cases have been reported in non-neutropenic settings also. We hereby present a series of ICA cases in non-neutropenic patients diagnosed at our tertiary care centre in Western India between March to October 2021. METHODS: All patients with clinico-radiological suspicion of CNS infections were analysed. Data regarding Clinico-radiological features, diagnosis, treatment and outcome were collected. After ruling out bacterial, viral and mycobacterial causes, appropriate samples were sent for KOH (potassium hydroxide) wet mount, fungal culture, histopathology and serum/CSF galactomannan. RESULTS: A total of four patients were diagnosed with ICA with a mean age of 43.5 years. Three patients had significant comorbidities; Diabetes mellitus, chronic liver disease and COVID-19 pneumonia treated with dexamethasone, respectively. One patient had no known predisposing factor. Radiologically, one patient presented with a frontal brain abscess and two patients had multiple subcortical hyperintensities. Three patients were diagnosed based on CSF galactomannan (Platelia™ Aspergillus antigen, Bio-Rad, France) with OD >1 and one patient had high serum galactomannan (OD >2). CSF culture grew Aspergillus species in two patients. All patients were treated with Voriconazole. One patient recovered, and the remaining three succumbed due to delayed presentation and extensive cerebral involvement. CONCLUSION: Even in non-neutropenic patients, a high index of suspicion is warranted for cerebral aspergillosis. CSF galactomannan can be considered a reliable marker for diagnosing ICA in non-neutropenic settings. Early diagnosis allows timely antifungal therapy, which could be a key to improving the outcomes.

Fungal endocarditis is a rare and fatal condition, most frequently caused by species of the genera Candida and Aspergillus. Fever and changing heart murmur are the most common clinical manifestations. The diagnosis of fungal endocarditis is challenging, with prosthetic valve endocarditis being extremely difficult to diagnose. The optimal management of the condition still remains debatable. We present a case of prosthetic valve endocarditis caused by Candida parapsilosis, managed empirically with liposomal amphotericin B, which was later shifted to combination therapy with high-dose echinocandin and fluconazole, but had a fatal outcome because the patient could not undergo timely surgical intervention. Treating C. parapsilosis endocarditis cases is difficult because of their biofilm production on native and prosthetic heart valves. A combined approach consisting of a high index of clinical suspicion, early diagnosis using serological markers followed by culture or PCR and prompt initiation of appropriate antifungals may aid in improving outcomes.
RESUMEN
The emergence of Mucorales infections is an urgent global public health threat rapidly disseminating during the current COVID-19 pandemic. Invasive mucormycosis carries significant morbidity and mortality; this is further compounded by the lack of newer effective antifungals on the horizon. Liposomal Amphotericin (L-AMB) is currently considered the cornerstone of antifungals therapy against mucormycosis; However, two decades later (since the introduction of L-AMB), the outcome remains dismal. Furthermore, adverse events related to therapeutic doses of L-AMB are also a hindrance. There is an imperative need for an alternative therapeutic approach to reduce the high mortality. One such approach is to combine the amphotericin with other agents (e.g., caspofungin, posaconazole, isavuconazole, and iron chelators) that can work synergistically or help in reducing the therapeutic doses of L-AMB. This review aims to highlight the various treatment approaches by gathering the clinical evidence from the literature and considering all potential pharmacological combinations that can provide the direction for future studies.

Introduction: Hepatitis B virus (HBV) is known as a metabolovirus due to its impact on lipid and glucose metabolism in the liver. Previous literature showed a trend of hypolipidemia and reduced risk of metabolic syndrome in hepatitis B surface antigen-positive patients. However, data from the Indian population are lacking. We evaluate the relation of lipid profile with HBV infection and severity of liver disease. Materials and Methods: This was an observational cross-sectional study in which 50 patients with chronic hepatitis B and 43 anthropometrically matched seronegative controls were enrolled. Demographical, clinical, and laboratory data including lipid profile (high-density lipoprotein [HDL], low-density lipoprotein [LDL], triglycerides, and total cholesterol [TC]) were collected. Seropositive patients were categorized based on prognostic models (model for end-stage liver disease [MELD] and Child-Pugh score) for further analysis. Results: Our study revealed significant low levels of serum TC, HDL, and LDL cholesterol in hepatitis B patients compared to seronegative controls (133.06 vs. 162.39, 35.56 vs. 43.65, and 76.62 vs. 99.95 mg/dl respectively, P < 0.05). The patients with high MELD and Child-Pugh score were associated with hypolipidemia. Significant low levels of LDL and TC were observed in Child-Pugh class C in comparison to class A (94.8 vs. 149.2 and 50.6 vs. 87.9 mg/dl respectively, P < 0.05). Conclusions: A significant reduction in various lipid parameters was seen with chronic hepatitis B. Furthermore, prognostic score (high MELD and Child-Pugh score) were associated with hypolipidemia.
Résumé Introduction: Le virus de l'hépatite B (VHB) est connu comme un métabolovirus en raison de son impact sur le métabolisme des lipides et du glucose dans le foie. Précédent la littérature a montré une tendance à l'hypolipidémie et à une réduction du risque de syndrome métabolique chez les patients positifs à l'antigène de surface de l'hépatite B. Cependant, les données de la population indienne font défaut. Nous évaluons la relation entre le profil lipidique et l'infection par le VHB et la gravité de la maladie hépatique. Matériels et méthodes: Il s'agissait d'une étude transversale observationnelle dans laquelle 50 patients atteints d'hépatite B chronique et 43 des témoins séronégatifs appariés ont été recrutés. Données démographiques, cliniques et de laboratoire, y compris le profil lipidique (lipoprotéines de haute densité [HDL], lipoprotéines de basse densité [LDL], triglycérides et cholestérol total [TC]) ont été collectés. Les patients séropositifs ont été classés en fonction de modèles pronostiques (modèle pour l'hépatopathie terminale [MELD] et score de Child-Pugh) pour une analyse plus approfondie. Résultats: Notre étude a révélé des taux sériques bas significatifs de cholestérol TC, HDL et LDL chez les patients atteints d'hépatite B par rapport aux témoins séronégatifs (133,06 contre 162,39, 35,56 vs 43,65 et 76,62 vs 99,95 mg/dl respectivement, P < 0,05). Les patients avec un MELD et un score de Child-Pugh élevés étaient associés à hypolipidémie. Des niveaux significativement faibles de LDL et de TC ont été observés dans la classe C de Child-Pugh par rapport à la classe A (94,8 vs. 149,2 et 50,6 vs 87,9 mg/dl respectivement, P < 0,05). Conclusions: Une réduction significative de divers paramètres lipidiques a été observée avec l'hépatite chronique B. De plus, le score pronostique (MELD élevé et score de Child-Pugh) était associé à une hypolipidémie. Mots-clés: Cholestérol, maladie hépatique chronique, hépatite B, hypolipidémie, métabolisme lipidique.

Cases with SARS-CoV-2 RT-PCR negative pneumonia are an understudied group with uncertainty remaining regarding their treatment approach. We aimed to compare the clinical and radiological characteristics of RT-PCR positive and clinically diagnosed RT-PCR negative COVID-19. This was a single-centre retrospective study conducted at a tertiary care hospital in Western India. All patients (age ≥18 years) with suspicion of COVID-19 with SARI (severe acute respiratory infections) who were subjected to RT-PCR testing (nasal/oropharyngeal swab) were included. Based on RTPCR results, patients were categorized and compared for demographic, clinical, and biochemical characteristics and outcomes. Out of 500 patients, 339 (67.8%) found RT-PCR positive. Except for the radiological findings, both groups differ in clinical presentation, disease severity (inflammatory markers), and outcome. RT-PCR-positive patients had raised ferritin, NLR (Neutrophil-Lymphocyte ratio), LDH, and high mortality compared to the swab-negative group. In-hospital mortality was also significantly high in RT-PCR positive group (HR=1.9, 95% CI=1.4-2.5, p=0.001). On multivariate analysis, NLR, ferritin, and d-dimer were the independent predictors of mortality in RT-PCR-positive (p=0.038, 0.054, and 0.023). At the same time, raised TLC (total leukocyte count) and procalcitonin were the risk factors for poor outcomes in RT-PCR-negative patients (p=0.041 and 0.038). We found significantly raised ferritin, NLR, and LDH levels and increased mortality in RT-PCR positive patients compared to RT-PCR negative. Incorporating clinical features, radiological, and biochemical parameters could be prudent while managing the RT-PCR-negative patients.
RESUMEN
BACKGROUND: The clinical spectrum of systemic nocardiosis encompasses pulmonary and disseminated disease. Central nervous system (CNS) involvement is an important feature of disseminated disease with significant mortality and high relapse rate, especially in those with suppressed cell-mediated immunity. This systematic review aimed to evaluate the epidemiology, clinical features, diagnosis, therapeutic interventions, and outcome in patients with CNS nocardiosis. METHODS: A literature search was performed in major databases (PubMed, Google Scholar, and Scopus) by using distinct keywords: "CNS disease," "Nocardia," "meningitis," "brain abscess," "disseminated disease," and "Cotrimoxazole." We included all patients ≥18 years with CNS nocardiosis reported between January 2000 and December 2020. RESULTS: A total of 129 papers were included in the final analysis. The mean age of patients was 55 ± 16 years, and the majority were male (70.8%). Nocardia farcinica was the commonest species (39.6%), followed by Nocardia nova (5.9%). Thirty-four percent of the patients were found to be immunocompetent. Corticosteroid use was the most common predisposing factor (55.8%). Among neuroimaging findings, brain abscess was most common (86.9%), followed by leptomeningeal enhancement (12.1%). The overall case-fatality rate in CNS disease was 22.8%. On multivariate analysis, patients who underwent surgery (OR 2.4, 95% CI 0.99-4.11, p value 0.046) had better survival than those treated with antimicrobial therapy alone. Immunodeficient state (OR 0.32, 95% CI 0.15-0.90, p value 0.019) was independently associated with poor outcome. CONCLUSION: CNS nocardiosis carries significant mortality, especially in immunodeficient patients. We advocate the use of surgery combined with antimicrobials to improve clinical outcome.

BACKGROUND: Amphotericin B is a pivotal drug for the management of invasive fungal infections. However, it has a significant toxicity profile with acute infusion reactions like fever, chills, vomiting, anaphylaxis, and nephrotoxicity in patients with long-term use. Pulmonary reactions mimicking acute pulmonary edema are unusual with amphotericin. CASE DESCRIPTION: We report a case of a 51-year-old male diagnosed with rhinomaxillary mucormycosis, who developed acute onset breathlessness, bilateral diffuse pulmonary infiltrates after amphotericin infusion. The patient recovered spontaneously within a few hours after the cessation of amphotericin, which was parallel with the normalization of Chest X-ray. Furthermore, the Naranjo adverse reaction probability score was 9, which established a definite causal relation between drug use and adverse event. CONCLUSION: Clinicians should be aware of acute lung injury in patients treated with amphotericin infusion. In cases with no alternative available, a slow infusion of amphotericin with close monitoring is required to prevent life-threatening pulmonary reactions.
RESUMEN
The landscape of fungal endocarditis (FE) has constantly been evolving in the last few decades. Despite the advancement in diagnostic methods and the introduction of newer antifungals, mortality remains high in FE. This systematic review aimed to evaluate the epidemiology, clinical features, diagnostic and therapeutic interventions in patients with FE. We also aim to examine the aforementioned factors as a determinant of mortality in FE. A literature search was performed in PubMed, Google Scholar and Scopus, and all patients ≥18 years with proven fungal endocarditis were included. A total of 220 articles (250 patients) were included in the final analysis. Candida was the commonest aetiology (49.6%), followed by Aspergillus (30%) and Scedosporium species (3.2%). The proportion of prosthetic valve endocarditis (PVE) and intravenous drug users was 35.2% and 16%, respectively. The overall mortality rate was 40%. On multivariate analysis, Aspergillus endocarditis (HR 3.7, 95% CI 1.4-9.7; p = .009) and immunocompromised state (HR 2.8, 95% CI 1.24-6.3; p = .013) were independently associated with mortality. Patients treated with surgery along antifungals had better survival (HR 0.20, 95% CI 0.09-0.42; p < .001) compared to those treated with antifungals alone. Recurrence of FE was reported in 10.4% of patients. In conclusion, FE carries significant mortality, particularly in immunodeficient and Aspergillus endocarditis. We advocate the use of surgery combined with antifungals to improve clinical outcomes.

BACKGROUND: Bloodstream infections (BSIs) are an emerging cause of significant morbidity and mortality in severe Coronavirus disease 2019 (COVID-19). We aimed to assess the prevalence, clinical profile and outcome of BSIs in critically ill COVID-19 patients. METHODS: This was a single-centre retrospective study conducted at a tertiary care hospital in Western India. All patients (age > 18 years) with reverse-transcription polymerase chain reaction (RT-PCR) confirmed COVID-19 admitted in the intensive care unit (ICU) were included. Hospital electronic records were searched for demographic data, time of bloodstream infection since admission, clinical profile, antimicrobial resistance pattern and clinical outcome of all patients who developed BSIs. RESULTS: Out of 750 patients admitted in COVID ICU, 8.5% developed secondary BSIs. All severe COVID-19 patients who developed BSIs succumbed to illness. A significant proportion of BSIs were Gram-negative pathogens (53/64, 82.8%). Acinetobacter baumannii was the commonest isolate, followed by Klebsiella pneumoniae (32.8% and 21.9%, respectively). Multidrug-resistance organisms (MDRO) were found in 57.8% of the cases. The majority of MDRO belonged to K. pneumoniae and Enterococcus groups. The proportion of Gram-negative bacteria resistant to carbapenems was 47.2% (25/53). On multivariate analysis, raised total leukocyte counts, mechanical ventilation and presence of comorbidities were significantly associated with the incidence of BSIs. CONCLUSION: We found a significant prevalence of Acinetobacter baumannii in COVID-19 associated BSIs. The presence of comorbidities raised leukocyte counts and mechanical ventilation should alarm clinicians for possible BSIs. The timely initiation of empirical antibiotics and rapid de-escalation is vital to improve the outcome. At the same time, strict compliance of infection control practices should be accomplished to reduce the occurrence of MDRO.

INTRODUCTION: Association of hearing loss has been found with a couple of febrile illnesses. Dengue fever is an arboviral febrile illness that is transmitted by Aedes mosquito. A case of sensorineural hearing was documented in the literature recently in dengue haemorrhagic fever. We are aiming to find if hearing loss occurs in dengue patients. METHODS AND METHODOLOGY: We assessed the hearing of ten patients diagnosed with Dengue fever from August 2018 to October 2018, prospectively. Patients who had a prior history of hearing loss or chronic suppurative otitis media were excluded from the study. Brief history, clinical examination and audiological assessment were made for all patients. All patients were followed up for three months with repeat audiological evaluation. RESULTS: Two patients complained of hearing loss after the onset of fever. They had a bilateral mild sensorineural hearing loss on audiological evaluation. One other patient was found to have bilateral high-frequency hearing loss although there was no complaint of hearing impairment. On three months follow up, both patients had bilateral mild sensorineural hearing loss with no improvement. CONCLUSION: Hearing loss in dengue fever, even though being mild in nature is irreversible. The cause of hearing loss in dengue is yet to be found. For the definitive association of hearing loss in dengue fever further studies are required.
RESUMEN
Gastrointestinal involvement in systemic lupus erythematosus (SLE) usually occurs in the form of mesenteric vasculitis, protein-losing enteropathy, intestinal pseudo-obstruction, and pancreatitis. We describe a 23-year-old female, a known case of SLE presented with significant ascites and pleural effusion. Further evaluation showed elevated CA-125 levels without evidence of malignancy. The patient was treated with corticosteroids, hydroxychloroquine, and azathioprine resulting in the resolution of ascites in 2 weeks. The triad of ascites, pleural effusion, and increased CA-125 is known as pseudo-pseudo Meigs' syndrome, which is rarely reported in the literature. Clinicians should be aware of this entity while evaluating an SLE patient with low serum-ascites albumin gradient (SAAG) ascites.

Aspergillus is a ubiquitous ascomycete that can cause a variety of clinical presentations depending on immune status. Central nervous system aspergillosis is a fatal disease with non-specific clinical features. The aim of this systematic review was to evaluate the epidemiology, clinical features, diagnosis and therapeutic interventions in CNS aspergillosis patients. We also aimed to examine the possible predictors of mortality in neuroaspergillosis. Literature search was performed in Medline, PubMed, and Google scholar and all patients≥18 years with proven CNS aspergillosis were included. A total of 175 articles (235 patients) were included in the final analysis. Their mean age was 51 years and the majority were male (57.4%). Overall case-fatality was 45.1%. Aspergillus fumigatus was the most common species (70.8%) followed by A. flavus (18.6%). Corticosteroids (22.6%), malignancy (19.1%) and diabetes mellitus (14%) were the most common risk factors. Neuroimaging findings included cerebral abscess (70.2%), meningitis (14%), infarction (13.2%) and mycotic aneurysm (8.9%). Disseminated disease (29.2% vs 17.8%, p 0.03), CSF hypoglycorrhachia (48.1% vs 22.2%, P: 0.001) and heightened CSF galactomannan (3.62 vs 2.0ng/ml, p 0.05), were the factors associated with poor outcome in neuroaspergillosis. Persons infected with Aspergillus flavus (13.1% vs 3.1%, P: 0.01), and having been treated with Voriconazole (51.9% vs 29.2%, P: 0.004) were more likely to survive. Our review will provide insight into the different spectrums of CNS aspergillosis. Notwithstanding the promising role of Voriconazole, future work is required to ascertain the role of combination antifungal therapy.

Finding spurious thrombocytopenia is a common occurrence in clinical practice, whereas pseudothrombocytosis is a very uncommon event. Despite several technical advancements in automated haematology analysers, a careful peripheral smear examination remains standard examination in cases of discrepancy of platelet counts. We are presenting a case of betathalassaemia intermedia who had pseudothrombocytosis, which was falsely labelled as myeloproliferative neoplasm before the patient visited our haematology clinic.

Introduction: COVID-19 is a highly infectious disease and varies in the severity of presentation as well as survival outcome due to varied inflammatory responses. Hence, the present study is aimed to evaluate the role of inflammatory markers in predicting the outcome of COVID-19 in hospitalized patients. Methods: A total of 272 confirmed COVID-19 patients were included in the study. Clinical and demographic data were collected. Biochemical, hematological, and inflammatory markers were assessed in all patients. Disease severity and primary outcome as survival and or mortality were recorded. Results:Hematological indices and inflammatory markers were significantly higher among the non-survivors. Interleukin-6 (IL-6) can differentiate non-survivors from survivors with 100% sensitivity and 70.2% specificity, with a cut-off value of 79.6 in the receiver operator curve (ROC). As disease severity was increasing, IL-6 and C-reactive protein (CRP) were significantly increased among patients. Survival analysis showed that an elevated level of IL-6 was significantly associated with mortality and Cox regression analysis showed the hazard ratio (HR) of IL-6 was 0.996 (P<0.007). Conclusion:The results of the present study implicate that increased levels of IL-6 and CRP were significantly correlated with severity and mortality in COVID-19 patients. In addition, the dynamic measurement of neutrophil-to-lymphocyte (N/L) ratio, IL-6, and CRP in COVID-19 might be used as predictors of prognosis and outcome.
