Mucormycosis is a rare and invasive fungal disease with high mortality rate caused by members of the order Mucorales. Mucorales species are vasotrophic organisms that may cause angioinvasive disease in immunosuppressed hosts. Risk factors include diabetic ketoacidosis, chronic kidney disease, organ or bone marrow transplantation, neutropenia, burns, malignancies, and steroid therapy. There are six different clinical presentations of mucormycosis, which includes rhino-orbital cerebral, pulmonary, gastrointestinal, cutaneous, disseminated, and miscellaneous infection. Here, we report a case of a 57-year-old male with stage-IV sarcoidosis on long-term steroids presenting with upper gastrointestinal bleeding and obstructive uropathy who was diagnosed with systemic mucormycosis. Biopsy obtained by endoscopy revealed necrotic debris with acute leukocytic exudate and numerous variably sized, 90-degree angulated fungal hyphae favoring mucormycosis-causing species. Imaging studies showed hydronephrosis, and cystoscopy findings were consistent with fungal infection of the bladder. Isavuconazonium sulfate was used as systemic salvage therapy along with continuous bladder irrigation with amphotericin-B for localized bladder infection after a trial with first-line systemic treatment with intravenous liposomal amphotericin-B failed. A repeat endoscopy showed inflammatory changes with a pathology report in which mucormycosis was no longer appreciated. The patient was discharged home to complete 6 months of antifungal therapy with monthly follow-ups. The patient has been asymptomatic after 12-month completion of therapy.
A previously healthy 21-year-old man presented with back pain, bilateral extremity pain, and right lower extremity weakness, paresthesias, and swelling. Sonographic examination revealed diffuse deep vein thrombosis (DVT) in the femoral and popliteal venous system. CT imaging revealed hypoplasia of the hepatic inferior vena cava (IVC) segment with formation of multiple varices and collateral veins around the kidneys. Hematologic workup also discovered a factor V Leiden mutation, further predisposing the patient to DVT. The rare, often overlooked occurrence of attenuated IVC, especially in the setting of hypercoagulable state, can predispose patients to significant thrombosis.
Acute generalized exanthematous pustulosis (AGEP) is a rare disorder characterized by an acute episode and sudden onset of erythematous and edematous eruptions of hundreds of sterile pustules. It is a self-limiting condition accompanied by fever and has a rapid course. It is mostly caused by drugs especially antibiotics. It is diagnosed by skin biopsy, which shows intracorneal pustules and neutrophilic infiltration in dermis and epidermis. We report a case of a patient who developed this rare skin condition with the use of piperacillin/tazobactam (Zosyn). This is only second case of AGEP reported in literature with the use of Zosyn.
Immune reconstitution inflammatory syndrome (IRIS) is a condition associated with paradoxical worsening and/or new onset of an opportunistic infection in HIV patients following the initiation of anti-retroviral therapy or switching to more potent antiretroviral therapy (ART) regimen. Although IRIS associated with many opportunistic infections (OIs) has been well reported, syphilis has very rarely been mentioned in this regard. A 52-year-old male, diagnosed with AIDS six weeks ago, presented with the disseminated non-pruritic painless skin rash. He denied any fever, cough, shortness of breath, and joint pain or swelling. The patient had no similar symptoms, genital ulcers, or any medical illness in the past. CD4 cell count and viral load were 40 cells/mm and 280,000 copies/ml, respectively, while screening tests for OIs including rapid plasma reagin test, quantiferon, cryptococcal antigen, and toxoplasma tests were negative at the time of HIV diagnosis. After three days of initiation of anti-retroviral therapy, he developed the above-mentioned skin rash. Repeat rapid plasma regain (RPR) test at this time was also negative. Punch biopsy of the skin lesion demonstrated findings suggestive of secondary syphilitic lesions, which was confirmed by immunostain. The repeat RPR, CD4 cell count, and viral load showed a titer of 1:256, 257 cells/mm, and 5000 copies/ml, respectively. His skin rashes faded away, and RPR titer trended down on treatment with benzathine penicillin without discontinuation of ART. The presence of an IRIS response does not predict overall HIV or OI treatment responses, and discontinuation of ART is not generally recommended as the benefits of treating HIV infection outweighs the risk associated with IRIS.
Sapovirus causes acute gastroenteritis (AGE) which manifests as severe diarrhea and vomiting. It is most often seen in, but not limited to, children and toddlers but can occur in people of all ages. It is typically more prevalent in low to middle-income countries but has also been reported in progressive countries such as the United States. Due to the universal use of reverse transcriptase-polymerase chain reaction (RT-PCR) testing, the reported incidence of sapovirus has continued to grow as the culprit agent in both AGE outbreaks and isolated cases. Its symptoms resemble what is seen with rotavirus but with a milder clinical course. This discussion explores the dire implications of a relatively understated pathogen. Here, we present a rare case of a 20-year-old woman who presented with septic shock secondary to severe gastroenteritis as a result of sapovirus infection.
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.
