RESUMEN
Patients with human immunodeficiency virus (HIV) have been reported to experience a spectrum of homeostatic dysregulation and resulting manifestations in their vascular system. This may be due to either disruption in the coagulation-anticoagulation pathways or due to damage to vessels from either HIV or other opportunistic infections. However, gangrene in an HIV-infected patient is an uncommon phenomenon. We herein report a case of a 30-year-old female, who had been taking antiretrovirals irregularly for 10 years, developing bilateral limb gangrene during her hospitalization for cryptococcal meningitis. Unfortunately, her condition continued to deteriorate and her attendants took her from the hospital against medical advice, with her death soon after. We illustrate how several biopsychosocial factors came together here to result in poor outcomes. To note, peripheral arterial disease (PAD) in HIV can rapidly lead to critical limb ischemia, resulting in limb gangrene. Aggravating risk factors for the same include smoking, poor glycemic control, and/or low CD4 T-cell count (<200 cells/mm3). General practitioners should be aware that HIV patients are far more prone to PAD than the normal population. Early recognition of at-risk patients, both medically and psychosocially, by family physicians is thus critical.
RESUMEN
BACKGROUND: Hypoxemia-induced endothelial dysfunction leads to microalbuminuria. Microalbuminuria (MAB) has also been used as a parameter to assess the risk of cardiovascular events in an individual. The aim of this study was to observe the relationship of MAB in patients with chronic obstructive pulmonary disease (COPD) and to correlate MAB with different stages of COPD. MATERIALS AND METHODS: This cross sectional study included 140 patients with COPD selected according to GOLD guidelines based on COPD test assessment score and the number of exacerbations who had smoking pack years of more than 10 years. Urine albumin creatinine ratio (UACR) more than 30 mg/gm represents MAB. RESULTS: The UACR increases as the severity of groups of COPD increases with significant differences in UACR values among different COPD groups. Significant differences were seen among various groups of COPD when compared for different clinical parameters such as SPO2, PaO2, PaCO2, pH, and C-reactive protein (CRP). Pearson correlation analysis revealed that UACR was significantly inversely related with PaO2 (r = -0.514, P < 0.001), SPO2 (r = -0.397, P < 0.001) and FEV1 (r = -0.441, P < 0.001) and it was significantly positively correlated with PaCO2 (r = 0.675, P < 0.001). CONCLUSION: This study indicates that there is strong relationship of MAB in patients with COPD and the levels of MAB increase as the severity of COPD increases due to hypoxia and endothelial dysfunction. As MAB is a marker for cardiovascular risk, patients with COPD can be routinely evaluated for the urine test of MAB specially who are at increased risk for cardiovascular events.
RESUMEN
Scrub typhus (ST), hitherto absent from many parts of India, is now recently being recognized as a significant cause of morbidity and mortality throughout the country. Its diverse clinical presentations, low of the index of suspicion by the treating physician, and lack of diagnostic testing in many parts of the country result in delayed treatment, leading to a host of complications. We here report such a complication, where ST manifested with a large intracerebral hemorrhage, of which, to the best of our knowledge, only nine cases have been reported in the English language worldwide. Family physicians, who are the often first point of contact for treatment of febrile illness, as ST typically manifests, need to be aware of this entity to prevent such catastrophic consequences.
