Acute primary CMV infection complicated by pneumonitis and ITP in young immunocompetent woman in a regional Queensland Hospital.

We present the first published case of simultaneous pneumonitis and immune thrombocytopenic purpura secondary to primary cytomegalovirus (CMV) infection in an immunocompetent patient. Treatment with oral valganciclovir for 2 weeks successfully led to complete clinical recovery. CMV is traditionally associated with infection in immunocompromised patients and neonates; however, evidence of severe CMV infections in immunocompetent hosts is emerging. It is important to highlight the broad range of clinical presentations of CMV infections to prevent diagnostic delay and associated morbidity and expense.

Systemic Antimicrobial Therapy for Diabetic Foot Infections: An Overview of Systematic Reviews.

Diabetic foot infections (DFIs) are a common complication of diabetes; however, there is clinical uncertainty regarding the optimal antimicrobial selection. The aim of this review was to critically evaluate the recent systematic reviews on the efficacy and safety of systemic (parenteral or oral) antimicrobials for DFI. Medline, Embase, CENTRAL, and CINAHL databases and the PROSPERO register were searched from January 2015 to January 2023. Systematic reviews with or without meta-analyses on systemic antimicrobials for DFI, with outcomes of clinical infection resolution or complications, were included. Of the 413 records identified, 6 systematic reviews of 29 individual studies were included. Heterogeneity of individual studies precluded meta-analysis, except for ertapenem versus piperacillin-tazobactam (RR 1.07, 95% CI [0.96-1.19]) and fluoroquinolones versus piperacillin-tazobactam (RR 1.03, 95% CI [0.89-1.20]) in one review. The application of the AMSTAR-2 tool determined two reviews to be of high quality. There was no statistical difference in the clinical resolution of infections for 24 different antimicrobial regimens (penicillins, cephalosporins, carbapenems, fluoroquinolones, vancomycin, metronidazole, clindamycin, linezolid, daptomycin, and tigecycline). However, tigecycline did not meet non-inferiority against ertapenem ± vancomycin (absolute difference -5.5%, 95% CI [-11.0-0.1]) and was associated with a higher incidence of adverse drug events. There is minimal systematic review evidence to suggest one regimen is superior to another for DFI.

Disseminated cryptococcosis presenting initially as lower limb cellulitis in a renal transplant recipient - a case report.

BACKGROUND: Cellulitis is an unusual presentation of disseminated cryptococcosis, a serious infection seen predominantly in immunocompromised hosts. Disseminated cryptococcosis carries significant morbidity for transplant recipients, especially of the pulmonary and central nervous systems, and carries a high mortality risk. CASE PRESENTATION: We report a 59-year-old renal transplant recipient who presented with bilateral lower leg cellulitis without other symptoms or signs. Failure of conventional therapy for cellulitis prompted a skin biopsy confirming cryptococcal cellulitis. Additional evaluation to exclude disseminated disease revealed Cryptococcus neoformans in blood cultures and cerebrospinal fluid (CSF). Treatment included reduction in immunosuppression regimen and targeted treatment for cryptococcal disease with liposomal amphotericin B and flucytosine followed by fluconazole consolidation and maintenance therapy. Treatment with liposomal amphotericin B and flucytosine followed by fluconazole consolidation and maintenance therapy achieved a good clinical response. Our patient achieved significant reduction in leg cellulitis and recovered without serious complication. CONCLUSIONS: This case suggests that cutaneous cryptococcosis in immunosuppressed patients warrants a low threshold for investigation for disseminated disease even in the absence of other symptoms or signs.
