RESUMEN
Background: Bacteremia is an uncommon complication of group A streptococcal (GAS) infections. The data on GAS bacteremia is scarce from developing nations such as India. Patients and methods: We performed a retrospective analysis of patients diagnosed with GAS bacteremia in a tertiary care hospital in Kerala, India over a 10-year period (2012-2021) by review of the electronic medical records (EMRs). Results: A total of 58 cases of GAS bacteremia were identified in the study period. Skin/soft tissue infection was the most common source of bacteremia. A total of 34.4% of the patients required ICU admission and the in-hospital mortality was 22.4%. All the GAS isolates were sensitive to penicillin, ampicillin, and ceftriaxone. Erythromycin and clindamycin resistance was seen in 39.7% and 24.1% isolates, respectively. Conclusion: This study shows that despite advancement in medical sciences, GAS bacteremia remains as a disease with high morbidity and mortality. A higher rate of clindamycin resistance was observed compared to previous Indian studies. How to cite this article: Jayakumar JS, Niyas VKM, Arjun R.

RESUMEN
Immune thrombocytopenia is a well-known complication of both HIV and Hepatitis C virus infections. Management becomes challenging when a patient with HCV-HIV co-infection presents with severe thrombocytopenia. Adverse drug reactions and drug interactions has to be considered while choosing treatment options for such patients. We report such a case which illustrates the difficulty in managing severe thrombocytopenia in HCV-HIV co-infected patients where evidence based clinical decision making helped in choosing the right therapy for the patient.

Necrobiotic xanthogranuloma is a rare dermatological manifestation of underlying hematological malignancies, in particular, when associated with paraproteinemia. These patients who are clinically symptomatic with chronic papules, nodules or plaques which demonstrate a histopathological pattern suggestive of extensive and frequently confluent areas of necrobiosis with granulomatous infiltration, warrant evaluation for an underlying monoclonal gammopathy.

Background: Viridans Group Streptococci (VGS) are a group of distinct species that can cause bacteraemia and other invasive infections. They are also among the common organisms causing infective endocarditis. Data on the epidemiology and clinical profile of VGS is limited, especially from India. Methods: We conducted an electronic medical record-based retrospective analysis of patients with VGS bacteraemia admitted to our hospital between January 2012 to December 2021. Blood cultures were incubated by BacT/ALERT system and bacterial identification and susceptibility testing were done by using the VITEK 2 microbial identification system. Susceptibility test reporting was as per Clinical and Laboratory Standards Institute (CLSI) guidelines. The incidence, clinical profile, source of bacteraemia, co-morbidities and antimicrobial resistance among VGS bacteraemia were analyzed. Results: VGS were isolated in 219 patients, accounting for 3.2% of positive blood cultures during the period studied. The median age of the patients was 58 years and 69% were males. Diabetes mellitus was the most common co-morbidity (55%) followed by chronic kidney disease and chronic liver disease. Patients with haematological malignancy and neutropenia were few. Intra-abdominal infections were the most common source of infection and was noted in 26%. Infective endocarditis was diagnosed in only 10% of the cases. Streptococcus mitis was the most common species isolated followed by S. gallolyticus and S. sanguinis. 9.58% of the isolates could not be identified up to the species level. Overall penicillin susceptibility was 71% and ceftriaxone susceptibility was 92%, with individual species variation. In-hospital mortality was 19%. Conclusions: VGS are an important cause of bacteraemia and was associated with 19% mortality in our study. High rates of penicillin and ceftriaxone resistance are a reason of concern. Molecular diagnostics like matrix assisted laser desorption ionization-time of flight (MALDI-TOF) identification must be increasingly applied for species identification considering that a substantial number of isolates were not identified to species level.
RESUMEN
Background: Peripherally inserted central catheters (PICCs) are central venous catheters inserted peripherally but terminate in great vessels. PICCs are widely used for patients requiring long-term intravenous therapy in both in-patient and out-patient settings. Aim: This study was carried out to understand PICC-related complications, specifically infections and causal pathogens, in a tertiary care hospital in Kerala, South India. Methods: A retrospective analysis of PICC insertions and follow-up during a 9 years period to look at patient demographics and infections related to PICC was carried out. Results: The overall PICC-related complication rate is 28.1% (4.98 per 1000 PICC days). Commonest complication was thrombosis followed by infection, either PICC-associated bloodstream infection (PABSI) or local infection (LI). PABSI noted in this study was 1.34 per 1000 catheter days. The majority (85%) of PABSI were due to Gram-negative rods. The average duration of PICC days for occurrence of PABSI was 14 days and the majority occurred in in-patients. Conclusion: Thrombosis and infection were the commonest PICC-related complications. PABSI rate was comparable to that of previous studies.
RESUMEN
Strongyloides stercoralis is a nematode helminth endemic to tropical and subtropical regions. Strongyloidiasis can manifest with varied clinical symptoms, predominantly gastrointestinal. Duodenal obstruction is an uncommon manifestation. We report such a patient with underlying Human T-lymphotropic virus type 1 (HTLV-1) infection.

Nosocomial outbreaks related to medication contamination are reported world-wide. A sudden increase in cases of Achromobacter spp. bacteremia led to an outbreak investigation in our setting. Line listing and environmental sampling led to identification of contaminated furosemide ampoules as the source. Molecular identification helped in species identification and in this outbreak more than one species was identified. Prompt withdrawal of the contaminated batch of ampoules curtailed the outbreak.
RESUMEN
Invasive pneumococcal disease (IPD) is a major burden causing significant mortality and morbidity. This study was conducted to ascertain the magnitude of the problem of drug resistance, the pneumococcal serotypes that are prevalent in our area, and whether current pneumococcal vaccines are able to cover the prevalent serotypes adequately. A retrospective study was done by reviewing the microbiology registry of our hospital. Details of patients whose blood, cerebrospinal fluid (CSF) or any other sterile fluid grew S. pneumoniae between the period January 1, 2016 and December 31, 2019 were collected. Identification and susceptibility testing were done by Vitek2 as per CLSI 2008 guidelines. Serotyping was attempted for 39 isolates. Fifty-five pneumococcal isolates in blood and CSF were identified over four years from 51 patients, of whom nine belonged to the paediatric age group. Among 55 isolates, 50 were isolated from blood, four had growth of pneumococci in both blood and CSF, and one had growth in CSF alone. Overall non-susceptibility to penicillin was noted in 11 isolates, and 10 isolates were non-susceptible to ceftriaxone. Common serotypes isolated were 9V, 19F, 23F and 6 B. The most common clinical presentation was pneumonia followed by sepsis and meningitis. Five of the 51 patients succumbed to the illness. Penicillin susceptibility among pneumococcal isolates in IPD was 80% and susceptibility to ceftriaxone was 82%. This observation reiterates the view that vancomycin must be added to the empiric therapy of suspected IPD. Most of the identified serotypes are covered by current pneumococcal vaccines, highlighting the pivotal role of pneumococcal vaccine in prevention of IPD.

CONTEXT: Nontuberculous mycobacteria (NTM) are ubiquitous mycobacteria present in environment and generally affect patients with either structural lung disease or immunosuppression and commonly involve lungs, lymph node, or skin. MATERIALS AND METHODS: Between July 2016 and February 2019, 18 cases of NTM were diagnosed and their relevant clinical, diagnostic, and treatment details were recorded after taking informed consent. RESULTS: We report 18 cases of NTM involving lungs (n = 11), skin and soft tissue (n = 3), joint (n = 2), genitourinary (n = 1), and central nervous system (n = 1). History of immunosuppression was present in two patients, whereas history of some form of intervention was seen in six patients. Mycobacterium fortuitum group (n = 5) was the most commonly isolated organism, followed by Mycobacterium avium complex (n = 4), Mycobacterium abscessus (n = 3), Mycobacterium kansasii (n = 2), and Mycobacterium chelonae (n = 1). In two patients, M. chelonae and M. abscessus were isolated in succession. Of these 18 patients, clinical response was present in 15 of the patients. Diagnosis and treatment of NTM in resource limited settings is extremely challenging. CONCLUSION: Most of the patients with NTM are misdiagnosed and are treated as tuberculosis in India, sometimes with a multidrug resistance regimen, which results in significant morbidity and mortality. We present these cases to shed some light on the epidemiology of NTM in this part of India.

With significant advancement in the tools and strategies available for diagnosis and management, there is an expected change in the epidemiological profile of patients living with HIV/AIDS (Human immunodeficiency syndrome/Acquired immunedeficiency syndrome). We retrospectively analyzed the changing epidemiological pattern of HIV infection over a period of 13 years in the anti-retroviral (ART) center of a tertiary care hospital in India. The study included a total of 9419 patients (8811 adults and 608 children) who were registered at our ART center between 2005 and 2017. Among adult patients, 68.9% patients were males and the mean age of presentation was 35.6±9.9 years. Heterosexual route was the most common route of transmission (95.5%). A total of 97.4% of pediatric patients acquired HIV infection via vertical transmission from their mothers. Most of the adult patients (77.1%) were educated only to primary level. Despite the economic growth in the country over the years, the monthly income of these patients has not significantly changed. The median CD4 count at the time of eligibility for starting ART was 244/µl of blood. An increasing trend in the baseline CD4 count was noticed from 2005 to 2017. Also, improved outcomes with less loss to follow up were noticed in the latter years. However, an increasing trend was also noted in the time gap between registration at the ART center and initiation of ART. Improvement in the baseline CD4 count and better treatment outcomes are indicators of a well-functioning national program. However, continued programmatic interventions are needed to further tackle the menace of HIV/AIDS in India.

BACKGROUND: Carbapenem-resistant Enterobacteriaceae has become a significant public health concern as hospital outbreaks are now being frequently reported and these organisms are becoming difficult to treat with the available antibiotics. CASE SUMMARY: An outbreak of VIM-producing Serratia marcescens occurred over a period of 11 wk (August, 1 to October, 18) in patients admitted to the adult polyvalent intensive care unit of the University of Campania "Luigi Vanvitelli" located in Naples. Four episodes occurred in three patients (two patients infected, and one patient colonized). All the strains revealed the production of VIM. CONCLUSION: After three decades of carbapenem antibiotics use, the emergence of carbapenem-resistance in Enterobacteriaceae has become a significant concern and a stricter control to preserve its clinical application is mandatory. This is, to our knowledge, the first outbreak of VIM-producing Serratia marcescens in Europe. Surveillance policies must be implemented to avoid future outbreaks.
