Balanced Crystalloid (Sterofundin) vs. Normal Saline for Diabetic Ketoacidosis: A Prospective Intervention Trial with Historical Controls.

BACKGROUND: Fluid therapy with normal saline (NS) in diabetic ketoacidosis (DKA) can cause hyperchloremic acidosis and delay DKA resolution. Balanced crystalloids may address this concern, though results with Ringer lactate and Plasma-Lyte have been mixed. AIM: This study aimed to compare the effectiveness of Sterofundin (SF) vs. NS in the management of DKA. METHODS: A prospective, intervention trial with historical controls was conducted at the Postgraduate Institute of Medical Education and Research, Chandigarh, India. Patients aged 13 years or older with DKA were enrolled. The primary outcome was the time taken to DKA resolution, with a predefined superiority margin of a one-fourth reduction in resolution time. Secondary outcomes included total intravenous fluid and short-acting regular insulin requirements, the need for 0.45% saline, hospital stay duration, and in-hospital mortality. RESULTS: A total of 150 patients (mean age 36.8 years, 56.7% males) were included, with 75 receiving SF (intervention group) and 75 receiving NS (historical control group). The SF group showed a significantly shorter mean time to DKA resolution (13.8 ± 6.0 hours) compared to the NS group (18.1 ± 5.5 hours; P < 0.001). SF patients required less total intravenous fluid (4500 mL vs. 6000 mL; P = 0.004), less insulin (98 units vs. 112 units; P = 0.017), and had a lower need for 0.45% saline (8% vs. 74.3%; P < 0.001). Patients receiving SF had shorter hospital stays (4 [IQR 3-5] days vs. 4 [IQR 4-6] days; P = 0.020). Mortality rates were similar between the groups (SF: 9.3%, NS: 8.1%; P = 0.791). CONCLUSION: SF may be a superior alternative to NS for fluid therapy in DKA.

Characteristics and Prognosis of Infectious Disease Emergencies in Patients with Chronic Kidney Disease in India.

Objectives: Chronic kidney disease (CKD) significantly increases the risk of infectious diseases (IDs), leading to heightened morbidity and mortality. However, there remains a lack of detailed, region-specific studies. This study investigates the clinical spectrum, etiologies, outcomes, and baseline predictors of mortality of ID emergencies in CKD patients in North India. Methods: This retrospective study was conducted at the Postgraduate Institute of Medical Education and Research, Chandigarh, from January 2021 to December 2022. It included patients aged ≥13 years with CKD and IDs admitted to the Acute Care and Emergency Medicine Unit. Results: We enrolled 248 patients (mean age 50 years, 58.1% males). About 60% had CKD stage 5, and 46% were on maintenance hemodialysis. Diabetic kidney disease was the predominant etiology (38.7%). The principal IDs were pneumonia (27.4%), urinary tract infection (UTI) (21.4%), sepsis of unknown primary focus (15.7%), tuberculosis (8.1%), and multisite infections (7.7%). Patients commonly have atypical clinical presentation, e.g., absence of fever and nonspecific symptoms such as shortness of breath and altered mental status. An emergence of multidrug-resistant organisms, e.g., Enterococcus faecium for UTI and Stenotrophomonas maltophilia for catheter-related bloodstream infections, was noted.In-hospital mortality rate was 33.5%, higher with multisite infections (58%) and pneumonia (47%). A low baseline Glasgow coma scale (GCS) was an independent predictor of mortality [odds ratio (OR) 0.786, 95% confidence interval (CI) 0.693-0.891, p-value <0.001]. Conclusion: Effective management and early intervention are needed to improve outcomes in CKD patients with ID emergencies, given the high mortality and atypical clinical presentations.

A case series of post-infectious chikungunya myeloradiculoneuropathy.

Chikungunya fever is an arboviral illness caused by chikungunya virus (CHIKV) and transmitted by the bite of Aedes aegypti and Aedes albopictus. It is an RNA virus belonging to the genus Alphavirus and family Togaviridae. We present a case series of three patients with chikungunya illness developing para/post-infectious myeloradiculoneuropathy.These patients developed neurological symptoms in the form of bilateral lower limb weakness with sensory and bowel involvement after the recovery from the initial acute episode of chikungunya fever. Clinical examination findings suggested myeloradiculoneuropathy with normal Magnetic Resonance Imaging of the Spine, with the nerve conduction study showing sensorimotor axonal polyneuropathy. All the patients were treated with 1 g of methylprednisolone once a day for five days, and case 2 was given intravenous immunoglobulin also. In the follow-up, cases 1 and 2 showed complete recovery without recurrence, and case 3 did not show improvement at one month.

Case Report: A Case of Complicated Typhoid Fever with Rhabdomyolysis and Hemophagocytic Lymphohistiocytosis.

Typhoid fever can have diverse extra-intestinal complications including encephalitis, Guillain-Barré syndrome, endocarditis, myocarditis, osteomyelitis, renal abscess, and splenic abscesses. Secondary hemophagocytic lymphohistiocytosis with rhabdomyolysis is a rare complication of typhoid fever. Here, we present the case of an adolescent with typhoid fever complicated by rhabdomyolysis and hemophagocytic lymphohistiocytosis.

Occult paraquat poisoning causing pneumomediastinum and organizing pneumonia.

Pneumomediastinum is not an uncommon manifestation of lung toxicity in acute paraquat ingestion. The condition is almost invariably seen with other lung parenchymal abnormalities such as consolidations, ground-glass opacities and interlobular septal thickening. The diagnosis may be challenging in cases with no history of toxin exposure, presentation with a subacute illness and/or absence of typical local or systemic features of paraquat toxicity.

Cerebrospinal fluid adenosine deaminase for the diagnosis of tuberculous meningitis.

Background: A consensus on the diagnostic utility of cerebrospinal fluid adenosine deaminase (ADA) for tuberculous meningitis (TBM) is lacking. Methods: Patients aged ≥12 years admitted with CNS infections were enrolled prospectively. ADA was measured with spectrophotometry. Results: We enrolled 251 TBM and 131 other CNS infections. The optimal cutoff of ADA was calculated at 5.5 U/l against microbiological reference standard with area under curve 0.743, sensitivity 80.7%, specificity 60.3%, positive likelihood ratio 2.03 and negative likelihood ratio 3.12. The widely used cutoff value 10 U/l had specificity 82% and sensitivity 50%. The discriminating power was higher for TBM versus viral meningoencephalitis than bacterial or cryptococcal meningitis. Conclusion: Cerebrospinal fluid ADA has a low-to-modest diagnostic utility.

The diagnosis of tuberculosis (TB) of the brain is mainly made by testing cerebrospinal fluid, a clear liquid that flows in and around the brain and spinal cord. Adenosine deaminase (ADA) is a protein whose production and activity are increased in many diseases, such as TB. ADA testing in cerebrospinal fluid is widely used for the diagnosis of brain TB. However, the experts have split opinions regarding its confirmatory role. This study explores ADA measurement in cerebrospinal fluid for differentiating TB from other brain infections. The report says that this simple and inexpensive test can be helpful, but it cannot make or refute the diagnosis of brain TB and should only be considered along with other tests.

Severe copper sulphate poisoning: A case rescued with plasmapheresis.

Acute copper sulphate poisoning is associated with multi-organ failure and high mortality. Patients typically present with gastrointestinal symptoms, haemolysis, methaemoglobinaemia, acute liver injury, rhabdomyolysis and renal failure. Management is usually supportive, and the role of chelation therapy has not been established. Copper is not dialysable. Plasmapheresis has been shown to remove protein-bound copper, reducing plasma and intracellular concentrations. We present a case of severe copper sulphate poisoning, who did not improve with chelation therapy with D-penicillamine and supportive care, but with therapeutic plasma exchange (four cycles) showed rapid clinical recovery.
