In Pakistan, HIV has converted from outbreak to concentrated epidemic and has also bridged into the low-risk population. The HIV epidemic in Pakistan mainly comprises subtype A. Here, we present the first case and genetic analysis of a circulating recombinant form 56_cpx in a Pakistani HIV-infected patient. Genetic analysis of the sequence indicated that Pakistani 56_cpx sequence had more drug resistance mutation than the other 56_cpx sequences available in the database.
Introduction Clostridium difficile ( C. difficile ) is one of the major causes of diarrhea transmitted by the fecal-oral route. C. difficile type BI/NAP1/027 is responsible for the most severe C. difficile infection (CDI). It is a major cause of antibiotic-associated diarrhea followed by Clostridium perfringens , Staphylococcus aureus, and Klebsiella oxytoca . Historically, clindamycin, cephalosporins, penicillins, and fluoroquinolones were related to CDI. We conducted this study to evaluate the antibiotics associated with CDI in recent times. Methods We conducted a retrospective, single-center study over a period of eight years. A total of 58 patients were enrolled in the study. Patients with diarrhea and positive C. difficile toxin in stool were evaluated for antibiotics given, age, presence of malignancy, previous hospital stay for more than three days in the last three months, and any comorbidities. Results Among patients who developed CDI, prior antibiotics for at least four days duration were given in 93% (54/58) of patients. The most common antibiotics associated with C. difficile infection were piperacillin/tazobactam in 77.60% (45/58), meropenem in 27.60% (16/58), vancomycin in 20.70% (12/58), ciprofloxacin in 17.20% (10/58), ceftriaxone in 16% (9/58), and levofloxacin in 14% (8/58) of patients, respectively. Seven percent (7%) of patients with CDI did not receive any prior antibiotics. Solid organ malignancy was present in 67.20% and hematological malignancy in 27.60% of CDI patients. Ninety-eight percent (98%, 57/58) of patients treated with proton pump inhibitors, 93% of patients with a previous hospital stay for more than three days, 24% of patients with neutropenia, 20.1% of patients aged more than 65 years, 14% of patients with diabetes mellitus, and 12% of patients with chronic kidney disease also developed C. difficile infection. Conclusion The antibiotics associated with C. difficile infection are piperacillin/tazobactam, meropenem, vancomycin, ciprofloxacin, ceftriaxone, and levofloxacin. Other risk factors for CDI are proton pump inhibitor use, prior hospital admission, solid organ malignancy, neutropenia, diabetes mellitus (DM), and chronic kidney disease (CKD).
BackgroundSkull base osteomyelitis (SBO) is an uncommon entity and carries a high mortality rate. It can be be odontogenic, sinogenic, or otogenic in origin, in addition to being a complication of skull surgery/trauma. Pseudomonas is one of the most commonly identified pathogen. The goal of the study is to describe the clinical spectrum, microbiologic characteristics, treatment, and its response among different patients with SBO. In addition, we compared the outcomes of bacterial and fungal osteomyelitis. MethodologyThis is a single-center retrospective analysis of patients with SBO who presented to Shaukat Khanum
